CONNECTION OF MODULES
This application claims the priority of the filing date of the German Patent Application No. 102010062312.1, filed on 1 December 2010.
The invention relates to a compound of modules, in particular and preferably in the furniture industry, and a method for the technical production thereof.
There are wood joints in the form of ridge strips and Schwalbenschwanzverbindun¬gen. These are glued and thus represent a permanent, fixed connection. The connection can no longer be solved.
AT 3711 U1 discloses that in a box at the opening side of the box adjacent first side wall carries a ridge strip and the first side wall gegenüber¬liegende second side wall has a first Gratnut whose cross section at least partially similar to the cross section of the outer ridge rail and formed in such a way. A ridge strip identical to said outer ridge bar can be inserted into the first ridge. Thus, a shelf can be built, which can be expanded as desired, which is adjustable without accessories and can be stored in the flat objects such as magazines or the like without additional accessories without risk of falling over or kinking.
US 6,357,960 discloses a non-protruding expandable clamping device.
Fig. 9 of US 6,357,960 shows two to be connected by means of the clamping device body whose length corresponds to the length of the clamping device.
US 2006/0165484 discloses a connection system for building materials. Fig. 1C of US 2006/0165484 shows an elongated connecting element for passing through a whole groove of a part to be connected.
DE 35 42 830 discloses a connecting element for connecting independent parts, which is integrally formed and has a convex cross-section with undercut flanks. It can be seen from FIG. 6 of DE 35 42 830 that a plurality of connecting elements are to be connected to each other by way of an extension, wherein each of these connecting elements may comprise a longitudinal slot and a longitudinal bore.
It is an object of the present invention to provide a system for connecting modules with high flexibility.
This object is achieved by the objects with the features according to the independent claims.
According to an embodiment of the present invention, there is provided a connecting member for connecting a first module to a second module, the connecting member having a central portion in which a gap is formed, a first engaging portion having a lower section extending from the central portion along a first direction for insertion into a first recess (in particular with undercut) of the first module and into a second recess (in particular with undercut) of the second module, a second engagement section extending from the central section along a second direction and having an undercut for insertion into the first recess of the first module and the second recess of the second module, wherein the second direction of the first direction is opposite, extending into the gap Spreizelementaufnahme for receiving a spreader and the spreader has, which for Ein¬f in the Spreizelementaufnahme is set up such that with the insertion of the first engagement portion in the first module and in the second module and the second Ein¬ handle portion in the first module and in the second module spreads, so that the first Mo¬dul and the second Module are releasably connected to each other by means of the connecting element.
According to another embodiment of the present invention, an arrangement for connecting a first module to a second module is provided, the arrangement comprising the first module having a first recess (in particular with undercut), the second module, the a second recess (in particular with undercut), and a connecting element having the features described above for connecting the first module with the second module.
According to yet another embodiment of the present invention, there is provided a method of making a connector for connecting a first module to a second module, the method comprising a blank (e.g., a wooden body) for forming a central portion of the blank is machined from under a first direction extending first engagement portion with undercut and for forming a from the central portion along a second direction extending second Eingriffs¬abschnitt with undercut, wherein the second direction of the first direction opposite, a gap is formed in the central portion, and subsequently a Spreizelementaufnahme extending into the gap for receiving a Spreizele¬ments is formed such that upon insertion of the expansion element in the Spreizelementaufnahme the first engagement portion and the second engagement portion each verse preizen.
According to yet another embodiment of the present invention, a method for connecting a first module to a second module by means of a connecting element is provided, wherein the first module has a first recess (in particular with a rear section) and the second module has a second recess (in particular with undercut), said connecting member having a central portion in which a gap is formed, a first engaging portion extending from the central portion along a first direction with an undercut, a second engaging portion extending from the central portion along a second direction Undercut, wherein the second direction of the first direction is opposite, a spreading into the gap hineinre¬ckende Spreizelementaufnahme and the expansion element, wherein in the method of the first engagement portion in the first recess and in the second recess a is guided, the second engagement portion is inserted into the first recess and into the second recess and the spreader is inserted into the Spreizelementaufnahme such that with the introduction of the first engagement portion in the first module and in the second module and the second engagement portion in the first module and in the second module, whereby the first module and the second module are detachably connected together by means of the connecting element.
According to a further embodiment of the present invention, a Ver¬ binding element is used with the features described above for connecting a first Möbel¬stücks as a first module with a second piece of furniture as a second module.
In the context of this application, an undercut of an engagement section is understood to mean, in particular, a physical projection of the engagement section, which faces away from a connecting surface of the two modules to be connected. Towards the sides of the two modules to be joined, this undercut should be concave (i.e., arched at least in sections) to exert a connection force on the modules. The term concave should be understood broadly so that in particular a non-differentiable shape (shaped, for example, as an angle or polygon with a re-entrant corner or inwardly projecting corners) can be understood. The undercut may, due to its shape, be insertable (for example insertable) into one or both correspondingly shaped recesses of the associated modules such that, after insertion of the fastener element along an insertion direction, withdrawal in an angled (in particular perpendicular) attachment direction due to at least partial form closure between the undercut engagement sections and the undercut recesses is difficult or impossible. In other words, the undercut engaging portion and the undercut recess form a positive connection on the outside or profile side, but still permit displacement in one before spreading
Insertion. Due to the spreading, this degree of freedom is reversibly made more difficult or even blocked due to an acting frictional force. As a result of the undercut, a constriction of the engagement sections to the connection plane is clearly apparent. The undercut does not have to act exactly in a form-fitting manner towards all interfaces; a mold closure along a part of the connection surface is sufficient.
In the context of this application is under a "detachable connection " a connection that, when properly deactivated, enables non-destructive disassembly of the previously connected components.
The operation of the connecting element according to an embodiment of the invention is based on the fact that its two engaging portions are first inserted into two corresponding recesses of modules to be connected, with a certain play, so that a user can accomplish this insertion comfortably and with little power. Subsequently, a user only has to insert the expansion element into the expansion element receptacle, whereby the gap widens in the central section and thereby wedges the engagement sections in the corresponding recesses of the respective module. Thus, the fastening action of the two modules by means of the connection element again occurs in a releasable manner. This means that after forming this solid connection, a release of the connection is again possible, by the skilled person understanding without significant damage of connecting element or modules, the spreader is simply led out of the Spreizelementaufnahme again. With regard to the strength of the strength, it should be said that the spreading is accompanied by a certain fastening frictional force and pressure force. By adjusting the degree of spreading, therefore, the strength of the user side is adjustable, in one to three dimensions.
Clearly after inserting - preferably with little play - the Verbin¬dungselements (without spreader) in the two opposite recesses of the modules only by inserting the expansion element, the areas on both sides of the gap by widening of the gap moved away from each other, with opposite undercut end portions of the two engagement elements a Pressure on adjacent surfaces berei¬che exercise the modules. As a result, the modules are held together positively and positively. The resulting holding force is effected by the undercut engaging portions and by each toothed portion being intermeshingly received in both recesses of the modules. This also works due to friction, when the front view of the connecting element is a rectangle, ie without teeth. The gearing makes the system better. Depending on the direction of the mechanism of action may be different.
In a manufacturing method for forming the connecting element is particularly advantageous that in a blank, for example, a solid body (in particular made of wood), by appropriate processing, first in opposite areas a respective engagement portion is formed with undercut. In the manufacturing method, only after forming the engaging portions of the gap and only then the Spreizelementaufnahmes partially formed in the gap. This represents a material-saving procedure, in which during the formation of the individual components in the blank, the already formed components are protected against a negative influence during subsequent processing steps.
In particular, for easy connection of modular pieces of furniture, the connecting element can also be used by private persons.
Further embodiments of the connecting element will be described below. These also apply to the arrangement, the method and the use.
According to an embodiment, the spreader receptacle may be formed only along a part of the length of the central portion. Corresponding to this, the expansion element can likewise be formed as a compact component, since it can be designed in one dimension (in particular with a length) which corresponds to the expansion element receptacle and is thus smaller than the length of the central section. As a result, a resource-saving, lightweight and cost-saving design is achieved, since the assembly can be faster, because a user needs to introduce the spreader only over a short distance in the Spreizelementaufnahme.
According to one embodiment, the connecting element may have a front-side end face and a rear-side end face, wherein the gap extends from the rear-side end face in the central portion and wherein the Spreiz¬elementaufnahme starting from the front end face hinein¬erstreckt in the central portion. The two end faces are to be understood as meaning those planar surfaces of the connecting element which are parallel to one another and whose normal vector is aligned parallel to the insertion direction. In any case, one of the end faces is not in contact with the respective modules in the mounted state. According to the described embodiment, the gap extends from another end of the connecting element than the Spreiz¬elementaufnahme. Thus, the gap and the Spreizelementaufnahme extend from the opposite end of the connecting element in each case towards a center of the connecting element. This simplifies the assembly. Furthermore, in this embodiment, the gap can no longer be seen in the mounted state. The screw can thus also be screwed into the connecting element (connector) from the other side of the gap. As a result, it is possible for the observer not to see the gap from the outside, but only the screw hole. Further, this feature provides better functionality since the connector can again be more easily removed and released from the recess in two furniture modules. Such an embodiment works particularly well with a connector of plastic or similar material.
According to an alternative embodiment, the connecting element may have a front-side end face and a rear-side end face, wherein the gap extends from the front end face in the central portion and wobeisich the Spreizelementaufnahme starting from the front end face hineinerstreckt in the Zentral¬abschnitt. According to this embodiment, the gap and the Sprei¬zelementaufnahme extend from the same end face of the connecting element. Such a Aus¬führungsform is particularly advantageous when using the material wood for Verbindungsele¬ment, since the then acting forces are particularly well compatible with the properties of wood.
The gap may be perpendicular to the contacted surfaces of the joined modules when assembled.
According to one embodiment, each of the exactly two engagement sections in each case both recesses of the two modules to be connected is introduced. Expressed differently, each of the recesses of the two modules is subdivided into a first recessed area, which is engaged by a part of the first engagement section, and subdivided into a second recessed area, which is engaged by a part of the second engagement section. This causes subsequent wedging a particularly strong, but still removable fastening.
Spreizelementaufnahme and gap may be formed as separate components or may be formed as a common contiguous recess. The Spreizele¬mentaufnahme serves functionally receiving the spreader, whereas the gap serves the lateral expansion of the connecting element when the spreader is received in the Sprei¬zelementaufnahme.
The expansion element can be sunk completely in the Spreizelement¬aufnahme in one embodiment, so that the survival of sharp components can be avoided.
The gap and the Spreizelementaufnahme may be integrally or mehrkomponentigausgebildet. The gap and the Spreizelementaufnahme can be provided as a common recess or as a separate recesses.
According to one embodiment, the gap may be formed over the entire thickness, but only over part of the length of the central portion, the thickness and the length dimensions of the connecting element being perpendicular to the first and second directions. By along the length, that is, the extension direction of the expansion element, the body of the connecting element is provided only over a partial distance with the gap, in another section still sufficient mechanical robustness erhal¬ten, which ensures an integrity of the body even with braces.
On the other hand, forming the gap throughout the thickness (that is, along the extent perpendicular to the extending direction of the expanding member) allows a homogeneous fastening force to be generated by the spreading or wedging of the engaging portions in the recesses of the modules. The wedging therefore captures the entire thickness of the body. But there are also two separate engagement sections possible, which are held together inappropriate form behind, so that a spread is possible. The basic body (i.e., connecting element exclusive expanding element) of the connecting element can thus optionally be formed by one-material or multi-material as well as one-piece or multi-component.
According to one embodiment, the first engagement portion and the second engagement portion may be formed symmetrically, in particular surface-symmetrical to the gap. The gap then clearly serves as a mirror plane. The area-symmetrical arrangement or. Formation of the two engagement portions to each other (for example, realized by a double dovetail) is reflected in a surface symmetric force distribution, which leads to a uniform fastening force, if the recesses are also symmetrical accordingly. With a mirror symmetry at the gap and with respect to the first direction, the connecting element can be arranged arbitrarily with respect to the modules, i. that incorrect operation is largely excluded. With mirror symmetry at only the gap or only with respect to the first direction, it can be defined how the modules are attached to each other.
According to an embodiment, in a top surface of the connecting member, which is pierced by the Spreizelementaufnahme in a puncture point, the first engagement portion and the second engagement portion may be formed point-symmetrical to the puncture point. Even such a point symmetry leads to a symmetrical introduction of force between the connecting element and modules, whereby the fastening force is increased.
According to one exemplary embodiment, the part of the first engagement section embedded in one of the modules and the part of the second engagement section embedded in this module may together be a dovetail, dovetail in which a part of the edges or all edges are or are rounded off, or be formed as a cuboid with one or more projections. However, the undercut recess should be concave in the broadest sense. A dovetail-shaped shaping of the engagement sections leads to a marked wedge effect. Even with the rounding of the dovetails, illustrative of forming a bone profile, a reliable attachment effect is achievable with good handleability. At the same time a safe handling of the engaging portions is possible, that they can be realized without sharp edges. This is advantageous, for example, in embodiments as a toy for children. By providing the engagement sections as cuboids with one- or multi-sided projections, it is possible to form approximately a type of hammer configuration (compare, for example, FIG. 7), in particular a double hammer, which may include an undercut for exerting the positive fastening force.
According to one embodiment, the expansion element may be cylindrical and / or have an external thread for screwing into the Spreizelementaufnahme and / or be wedge-shaped and / or formed as a thread-free bolt. For example, in a substantially cylindrical configuration, the spreader may be a nail. With simultaneous provision of an external thread, the expansion element can be designed as a screw. However, it is possible to provide the spreader element as a wedge or the like so that the wedge can then be driven into an expanded portion of the gap forming the spreader receptacle to activate the releasable connection. For example, with a tool (for example a pair of pliers) or by hand, the wedge can then be removed again. Such a wedge shape can also be used in an exemplary embodiment in which a non-detachable connection is to be created. Also, a thread-free bolt can be driven into the Spreizelementaufnahme, for example be hammered in order to then accomplish the spreading.
According to one embodiment, an end face of the spreader element may have an An¬greifprofil (for example, at least one correspondingly shaped groove or at least a correspondingly shaped protrusion) for engaging a tool for inserting the spreader into the Spreizelementaufnahme and for removing the spreader from the Spreizelementaufnahme. Advantageously, for example, a hexagonal profile, a slot or a cross-section can be formed in the end face of the expansion element, which can be arranged perpendicular to a main extension direction of the expansion element in the Spreizelementaufnahme. By re-using the tool, for example by turning a screwdriver now in the opposite direction, then the reversible Entfer¬nen of the expansion element from the Spreizelementaufnahme and then the Verbindungs¬elements from the arrangement can be done.
According to an embodiment, the first engagement portion and the second engagement portion may have an outer profile formed to be uniform along the entire extension parallel to an extending direction of the expansion element receiver. In other words, by the constant profile in a direction of insertion for insertion into an elongate groove, insertion of the respective engagement section into an appropriate recess of the respective module can also take place over a relatively long distance.
The connecting element need not be completely inserted into the recesses, it can be completed exactly with the module edges or be introduced into at least one of the modules. Common to these variants is that there is an area which holds the modules in a form-locking manner during distortion. The location of this area is predetermined by the gap. However, the fit need not necessarily be made across the entire area of the gap. This area should be within both modules. The profile of this area specifies the maximum dimensions of the profile for the remaining recessed area.
According to one embodiment, the Spreizelementaufnahme may be cylindrical, in particular cylindrical with an internal thread. Such a cylindrical hole can be formed by correspondingly drilling a blank, which then in the machined state together with an associated expansion element forms the connecting element. It is optionally possible, after drilling such a cylindrical hole, to screw a self-tapping screw into the expansion element receptacle in order to cut the internal thread.
According to one embodiment, the gap may be formed as a recess plane. According to this configuration, the gap is formed as a planar planar gap, in the thickness direction of which the gap has a substantially smaller extent than in two orthogonal directions of extension. For example, the thickness of the gap may be at most 1/5, in particular at most 1/10, of such an expansion in the two orthogonal directions of extension.
The Spreizelementaufnahme may be formed slightly smaller than the spreader, so that by inserting the spreader in the Spreizelementaufnahme a Sprei¬zung can take place.
According to an embodiment, the gap along the first direction and the second direction may have a smaller extent than the Spreizelementaufnahme. In contrast, the gap in a direction orthogonal to the first and the second direction third direction, which lies in a surface plane of the connecting element, which is pierced by the Spreizelement¬aufnahme, a greater extent than the Spreizelementaufnahme haben.Ein part of the gap can thus with the Spreizelementaufnahme coincide, so that a driving of the expansion element in the Spreizelementaufnahme leads directly to a symmetrical in the first and in the second direction expansion of the gap, whereby a double-sided uniform force can be made by the connecting device in the modules.
According to one embodiment, the gap can be widened on its end face, in particular be widened in a cylindrical manner. The end face of the gap can be understood to mean an end face of the gap in the interior of the body at which an extension of the gap ends in the body. By widening the thin parallelepiped-shaped gap on its front side, for example in the form of a cylindrical bore, unwanted fuzziness at this point during insertion and subsequent removal of the expansion element into the expansion element receptacle can be reliably avoided. As a result, the connecting element can also be used many times, without fear of deterioration of the connecting element due to the reversible insertion and subsequent removal.
According to one embodiment, the connecting element may comprise or consist of wood, in particular solid wood (ie solid wood). Wood products are referred to as solid wood, the cross sections of which have been worked out from a tree trunk and possibly further machined (drilling, milling, planing, etc.). Other usable forms of wood are wood-based materials which are produced by comminuting wood and then joining the structural elements together. Examples include plywood, wood chipboard (chipboard) or wood fiber (hardboard). It has been found that wood is a particularly suitable material for the fastener that can be easily machined to form the individual components of the fastener. At the same time, wood is sufficiently stable and yet can provide a degree of flexibility in order to be able to use the connecting element several times. Solid wood is particularly well suited because of its properties as a material for the body of the connecting element. However, other materials for the body of the fastener are also possible, for example metal, composites, glass fiber, rubber, steel or plastics. Other materials are possible.
Further, further embodiments of the arrangement will be described. These also apply to the fastener, the methods and the use.
According to one embodiment, in the insertion direction of the connecting element in the first recess and the second recess, the connecting element has a smaller length than the first module and / or the second module. The direction of extension of the respective module or connecting element along which the binding element is inserted into the recesses of the modules when the arrangement is used as intended can be understood as meaning the direction of insertion. In the described embodiment, the connecting element can be made shorter than the modules which are to be fastened together by means of the connecting element. Unlike conventional can be worked with very small volume and compact fasteners as well as with large Modu¬len. This is based on the recognition that due to the exceptionally strong holding force of the connecting elements, it is already sufficient for two modules to be connected together by means of the connecting element along a relatively short distance and for the invention to be dispensable along the entire extent of the modules. This results in a compact, lightweight and easy-to-handle connection assembly.
According to an embodiment, the first engagement portion and the second engagement portion may only partially fill the first recess and the second recess, respectively. In particular, in this embodiment, the recess can be formed along an entire side surface of the module.
A connecting element can then be introduced, for example, only in an initial region of the recess. Or two connecting elements can be introduced into an initial area or into an end area of the recess, so that an intermediate area between the starting area and the end area can remain free of material. In terms of manufacturing technology, it is particularly cost-effective to form the recess (for example ridges) over the entire side surface, so that two corresponding recesses form a passage hole (instead of a blind hole). The connecting elements then extend only over part of the length of the respective cutout into this cutout.
According to an alternative embodiment, the first engagement portion and the second engagement portion may completely fill the first recess and the second recess. According to this embodiment, the dimension of a recess (wherein two korres¬pondierende recesses together form a blind hole) may be adapted to the dimension of the Verbin¬ element. In other words, a length of the recess and a length of the respective connecting element in the insertion direction may be the same (or may be the same except for differences due to a technical condition). Then, in the assembled state, the connecting element terminates flush with a cover surface of the modules mounted on one another, and cavities in the interior of the modules mounted on one another are avoided.
According to one embodiment, the length of the connecting element may be at most approximately 1/2, preferably at most approximately 1/3, particularly preferably at most approximately 1/4 of the length of the first module and / or the second module. For example, the length of the connecting element can be between 1% and 25% of the length of the modules in the insertion direction of the connecting element. It has been found that even these short connecting sections are sufficient to reliably connect even large-volume modules to each other. According to other embodiments, however, the length of the connecting elements can be greater than 1/4, for example between 10% and 80%, in particular between 20% and 50%.
At the same time, according to one embodiment, the length of the Verbindungsele¬ments at least 1%, in particular at least 5%, the length of the first module and / or the second module amount. Thus, a reliable holding action between the first and second module can be effected and unwanted separation of the modules can be prevented.
According to one embodiment, the first module and / or the second module may each be formed as a hollow cuboid having at least one side wall, wherein in the side wall, the respective recess or recesses is or are. The recesses may be in the direction of the interior of the hollow cuboid may be formed on the side of the side wall of the cuboid facing outward in the opposite direction. Such cuboids, in which the recesses are formed on the outer side of the side wall of the cuboid, can be arbitrarily engaged with each other to make it possible to construct any pieces of furniture, such as cupboards, beds or dressers.
According to an embodiment, the first module may be formed as a first side wall and the second module as a second side wall, wherein in the side walls, the respective recess may be formed corresponding to each other such that for Aus¬ forming a corner joint by inserting the connecting element into the Ausnehmendie first side wall with the second side wall at an angle, in particular at right angles, connected. Therefore, the connecting element according to the invention can be used not only for forming bonds between mutually parallel side walls in adjacent modules, but also for forming corner joints between flat plates, for example, orthogonal to each other.
According to one embodiment, the recesses of the first module and the second module may be arranged symmetrically and / or in the same dimension (in particular at equal edge distances to respective module ends), whereby different modules can be flexibly connected by a user. With such an arrangement, it is possible to have very different modules connected to one another, since, when the corresponding modules are put together, the corresponding recesses each form a common recess, which corresponds to the geometry of the connecting element.
According to one embodiment, the first module and / or the second module may each have exactly one recess with undercut, in each of which the / the connecting element (s) can engage.
According to one embodiment, the first module and / or the second module may have at least one further recess with an undercut, in particular running parallel to the first recess. In particular, the two modules may each include four recesses on each of the side walls, thus allowing flexible connection of the modules. The plurality of recesses per module may be formed so that the directions of insertion of connecting members into the respective recesses are parallel to each other. However, the plurality of recesses per module can also be designed in such a way that the directions of insertion of connecting elements into corresponding recesses form a right angle to one another; it is also possible for the directions of insertion of connecting elements per module to form an arbitrary angle.
In one embodiment, using the releasable connector, a user may build and remodel furniture from a set of different blocks / cubes (e.g., desk, bed, shelves). Thereby, a piece of furniture, a system or a combination arrangement of modules can be provided, in which the modules with substantially rectangular cross-section, for example modules designed as hollow cuboid or as rectangular in cross-section plate-shaped modules, at at least two opposite side surfaces of the module ridge recesses in regular distance , The modules can be juxtaposed and / or superimposed and be connectable by means of the Ver¬ binding elements. The ridge recesses may preferably be arranged on the edge of a side surface. They may face each other in pairs (i.e., at the front and rear sides) so that at least one burr recess may be located at least at each of the four side surfaces of the module in a cuboidal module. Open gate recesses may be covered with a filler or aperture.
In the state inserted into the modules, the gap of the connecting element extends into the recesses of both modules.
According to one embodiment, the first (in particular undercut) recess may be formed as a first ridge strip in a surface region of the first module and / or the second (in particular undercut) recess may be formed as a second ridge strip in a surface region of the second module. A ridge strip can be understood as a (in particular undercut) groove which can be machined into a planar surface of a module. In other words, a ridge strip does not necessarily have to be realized by placing a separate component extending beyond a surface plane of the module, such as an attachment strip (although this is possible in one embodiment), rather the ridge strip may be integral with and thus integral with the module wall be formed. This also makes it possible to arrange directly adjacent to one another, for example with direct contact with each other, of the two modules, which can then integrate the entire extent of the connecting element in the two ridge strips of the two modules which are directly adjacent to one another. This ensures a space-saving and reliable connection of the two modules. The front side of the Ausspa¬ ments should lie on the edge of the module, so that one can introduce the connecting element.
According to one embodiment, the first module and / or the second module may each be in the form of a hollow cuboid (or cuboidal hollow body) with at least one side wall (which may have a flat outer surface). In the side wall, the respective recess may be formed. Thus, an interior of the two modules may have a storage space, for example shelves and / or drawers. On the side wall or the side walls of such a hollow cuboid, any number of intersected recesses, for example in the form of ridge strips, can or can then be attached. These can be arranged, for example, symmetrically and / or in the same dimension, in order to maximize the flexibility of connecting different modules by a user.
According to one embodiment, the first module and / or the second module may have at least one further recess with an undercut, in particular running parallel to the first recess. Thus, a plurality of recesses may be provided in a single module, wherein the recesses may be arranged logically (in particular with respect to spacing from each other and to edges of the module) so that a flexible connection with any other modules is possible. From a set of at least three module types, a user can then pick out any combination of at least two modules and connect them together in a user-definable manner using one or more connectors. In particular, in juxtaposition of several modules side by side also a multiple attachment to two or more mutually parallel recesses of the two modules possible in order to further strengthen the Befε¬tigungswirkung.
According to one embodiment, in the first module and / or the second module, at least one further recess may be formed in the same side wall in which the other recess is also formed. Alternatively or additionally, in the first module and / or the second module, at least one further recess may be formed in a different side wall than that in which the other recess is formed. Thus, according to one embodiment, a sidewall may be provided with a plurality of recesses. According to another embodiment, different side walls can be provided, each of which can have at least one, but preferably several, of the recesses.
According to one exemplary embodiment, the first module and / or the second module may comprise or consist of wood, in particular layer-glued wood. Under layer-glued wood, a laminate of several wood layers can be understood, which are connected to one another by means of wood glue. Laminated wood is inexpensive and yet is excellently suited as a material for the modules, especially if they are to be connected to a solid wood fastener. Although wood is not the only material that can be used for the modules, wood has proven to be an especially suitable material. Wood has sufficient flexibility to absorb the stresses during wedging, so that damage does not occur even in the wood modules when a connecting element is inserted several times in the corresponding recesses and subsequently removed therefrom. At the same time, however, wood has sufficient strength.
According to one embodiment, a shrinkage of the material of the first module and / or the second module may be chosen to be greater than or equal to a shrinkage of the material of the connecting element. The shrinkage is a parameter for the hygroscopic properties of wood and wood-based materials, which describes the dimensional change of a workpiece depending on the water content. In particular, the shrinkage is the change in the release of the moisture contained (shrinkage). When the indicated ratio of shrinkage is present, a reliable releasable connection is provided which will be permanently maintained even in the event of leakage of residual moisture remaining in the wood.
According to one embodiment, the arrangement may comprise at least one filler element adapted to fill a portion of the respective recess which is free of a respective engagement portion such that the portion filled with the filler element terminates flush with a surrounding surface of the respective module. Such a filling element may be optionally provided to portions of the recesses of the
Module walls to fill and thus avoid sharp edges. Thus, even if the engagement sections only partially fill the recesses of the modules, thanks to one or more filling elements, the corresponding module also fits flush with the environment even after attachment, whereby the filling elements can be conveniently inserted (in particular inserted) into the modules themselves after the attachment has already been realized.
A fastening force of the filling elements in the recesses may, for example, be frictionally engaged (for example, purely).
Further embodiments of the manufacturing method are described below. These also apply to the connection element, the arrangement, the connection method and the use.
According to an embodiment, a blank (for example a cuboid) for forming the first and the second engagement portion may be machined by milling. Milling, in particular of wood blocks or wooden strips as a blank, is a simple but reliable method with high precision in order to form the engagement sections.
According to one embodiment, the formation of the gap (with rounded Stirn¬fläche) drilling a hole perpendicular to the first and the second direction and senk¬recht to an extension direction of the Spreizelementaufnahme, and a (in particular nach¬folgendes) sawing a Recess plane between the hole and a surface plane of the connecting element, wherein the recess plane extends perpendicular to the first and the second direction. The sawing can take place starting from the surface plane towards the hole. Thus, the gap formation can be made first by drilling to set the end face of the gap. This not only defines the end region of the gap, but at this point also ensures protection against fraying or for forming a turning edge around which the rotation takes place for forming the wedging. If then, for example, with a jigsaw, the cleavage plane is formed, so this is also possible with gerin¬gem effort and with high precision.
According to one embodiment, to form the spreader receptacle, a longitudinal hole perpendicular to the first and second directions may be drilled through at least part of the gap from a surface plane of the connector. According to this embodiment, particularly with the milling of the engagement portions and the drilling and sawing of the fastener Gap can be connected, only after the formation of the gap, the Spreizelementaufnahme, for example, formed in a cylindrical manner by screwing a screw.
A further embodiment of the connection method will be described below. This also applies to the connection element, the arrangement, the manufacturing method and the use.
According to one embodiment, in the method, the expansion element can be led out of the expansion element receptacle in such a way that the spreading out of the first engagement section in the modules is canceled out and the spreading of the second engagement section in the modules is canceled out , wherewith the first module is released from the second module. Thus, by merely removing (for example, unscrewing in the opposite direction to the previous screwing in) of the expansion element from the Spreizelementaufnahme the connection destructive and the connection element from the recesses in the modules force-free or force-arm removed. With the lead out occurs despreading, so that the connection is dissolved.
Furthermore, a method for connecting a first module to a second module by means of a connecting element is described, wherein the first module has a first recess and the second module has a second recess, wherein the Verbindungsele¬ment a central portion in which a gap is formed in that an undercut first engaging portion extending from the central portion along a first direction, an undercut second engaging portion extending from the central portion along a second direction, the second direction being opposite the first direction, extending into the gap Spreizelementaufnahme and the Spreiz¬element, wherein in the insertion direction of the connecting element in the first recess and the second recess, the connecting element has a smaller length than the first module and the second module. The method has the following steps; Inserting the first engagement portion into the first recess and into the second recess; Inserting the second engagement portion into the first recess and into the second recess; and inserting the expansion element into the expansion element receptacle in such a way that with insertion the first engagement section in the first module and in the second module and the second engagement section in the first module and in the second module are braced, with which the first module and the second module is releasably connected to each other by means of the connecting element.
Further, the described method may further optionally include extracting the spreader element from the spreader receptacle so that the dislodgement removes the spread of the first engagement portion in the modules and releases the dislocation of the second engagement portion in the modules, thus disabling the first module of FIG the second module is solved.
Further, a connector of an assembly for connecting a first furniture as a first module to a second furniture as a second module may be used.

The same or similar components in different figures are given the same reference numerals.
Hereinafter, referring to FIG. 1, a connector 100 according to an exemplary embodiment of the invention will be described.
The connecting element 100 is designed to connect a first module (not shown in FIG. 1) to a second module (not shown in FIG. 2) and is made from a substantially cuboid or substantially strip-shaped wooden blank as the basic body. In a central portion 102 of the base body, a thin gap 104 is gebil¬det.
Starting from the central portion 102, along a first direction 106, a first engagement portion 108 in the form of a first dovetail profile having a backcut 110 extends. The first dovetail profile is designed for insertion into correspondingly formed sections of a recess of the two associated modules (see FIG. 3).
Along a second direction 112, which is opposite to the first direction 106 (that is to say turned counter to the first direction by an angle of 180 ° or approximately 180 °), a second engagement section 114 extends, on which Slit 104 symmetrically mirrored arranged dovetail profile also with undercut 116. The second dovetail profile is designed for insertion into correspondingly formed other portions of the recesses of the two associated modules (see Fig. 3).
In the gap 104 extends a Spreizelementaufnahme 118 in the form of a cylindrical bore with thread for receiving a screw body with Außen¬gewinde as expansion element 120. When the expansion element 120 is not inserted in the Spreizelementaufnahme 118, there is the machined Solid wood blank in a voltage-free state and can be moved in the respective recesses of the modules to be connected with a certain play, for example, be inserted into a ridge strip. However, when the spreader 120 is inserted into the spreader receptacle 118, the two engagement portions 108, 114 are pushed outwardly from the central portion 102, and the gap 104 widens. Thus, with the insertion of the expansion member 120, the first engagement portion 108 in the respective recess portions of the first module and the second module and the second engagement portion 114 in the other corresponding recess portions of the first module and the second module expand. By this spreading, the keyed engagement portions 108 and 114, respectively, are jammed or keyed in the recesses, which effects attachment between the modules by means of the connector 100. Only by unscrewing the expansion element 120 from the Spreizelement¬aufnahme 118, the wedging reversible reversible, so that after removing the expansion element 120 from the Spreizelementaufnahme 118, the non-wedged Verbindungsele¬ment 110 with little effort from the two recesses in the adjacent Mo¬dule can be pulled out. The modules are then separated again.
As can be seen from FIG. 1, the gap 104 is formed over the entire thickness D, but not along a portion of the length L of the central portion 102. The thickness D and the length L are dimensions of the connecting element 100 perpendicular to the first direction 106 and to the second direction 112, respectively. As a result, an end portion of the connecting element 100 that is free of the gap 104 (that is, the region shown in FIG behind reference symbol 128) contribute to the stabilization.
The shape of a cross section of engagement portion 108 is obtained by mirroring the engagement portion 114 on an axis formed by the gap 104 in the cross-sectional plane. In other words, the engagement portions 108, 114 are mirror-symmetrical to each other with respect to gap 104. A piercing point of the expansion element receptacle 118 through a surface plane 122 of the connecting element 100 (front side in FIG. 1) forms a mirror point with respect to which the first engagement section 108 is point-symmetrical to the second engagement section 114 as a double-dovetail profile in the surface plane 122. In the surface plane 122, that is to say the end face of the connecting element 100, the expansion element receptacle 118 lies in a geometric center of gravity.
In the longitudinal direction (see reference character L) perpendicular to the surface plane 122 remains the profile of the engagement portions 108, 114 along the entire extension of Verbin¬dungselements 100 continuously and consistently dovetailed. Thereby, the connecting element 100 can be inserted into a correspondingly shaped groove of a module over a larger dimension.
As shown in Fig. 1, a hexagonal profile 126 for engaging by a corresponding hex tool (not shown) is formed as a groove on the end face of the expanding element 120. The hexagonal tool is used for screwing the spreader element 120 designed as a screw into the expansion element receptacle 118 or for unscrewing the expansion element 120 from the expansion element receptacle 118.
At its end face 128, the gap 104 is widened in a cylindrical shape. In other words, fraying or fraying in such an end portion of the gap 104 can be avoided by stabilizing this end portion by a cylindrical hole.
2 shows a multiplicity of different modules, including a first module 200 and a second module 202, all of which can be permanently but detachably connected to one another with connecting elements 100 in any user-definable combination. Side walls 208 of the first module 200 are provided with recesses 204, and Seiten¬ walls 208 of the second module 202 are provided with recesses 206. Furthermore, walls 212 are provided with recesses 210. If sidewalls 208 of two modules 200, 202 are applied to each other with contact with each other, their recesses 204, 206 together form double dovetail recesses or, more generally, double profile recesses, which are designed as connecting elements according to a double profile.
2 shows a plurality of furniture modules, which can all be modularly combined with one another and can be fixedly connected to one another by means of connecting elements 100 according to FIG. 1. At the same time, solvability of the furniture modules can be achieved by eliminating the wedging effect. For example, the connector 100 may be as shown in FIGS. 1 for connecting the side walls 208 of the two modules 200, 202 are used.
FIG. 2a shows an enlarged view of the two modules 200, 202.
3 shows a connection arrangement 300 according to an exemplary embodiment, in which two modules 200, 202 are shown as layer-glued wooden walls, which are connected flush to one another by means of a connecting element 100. First, the connecting element 100 is introduced by hand into the recesses of the modules 200, 202 and then wedged by means of the expansion element 120 with the modules 200, 202.
FIG. 3 shows a joining surface of the two modules 200, 202 with reference numeral 302, end faces of the modules 200, 202 with reference numeral 304 and side faces of the modules 200, 202 with reference numeral 306.
Fig. 4 shows another embodiment of a connection arrangement of two modules 200, 202 and another connecting element 100, which is not doppelschwalben¬ tail shaped, but as a cuboid with two prismatic (here a prism mitdreieckiger base) protrusions is formed. As a result, an undercut profile is introduced in each recess of the modules 200, 202 on only one side. A Spreizelementaufnahme 118 in this embodiment has a rectangular cross section, which can be filled for Bei¬spiel with a bolt with a rectangular cross-section.
Based on the Spreizelementaufnahme 118, the engagement portions 108, 114 have a point-symmetrical configuration.
As an alternative to a dovetail double profile as connecting arrangement, FIG. 5 shows an arrangement with rounded edges, which can be referred to as bone-shaped.
6, a wedge 120 is used instead of a screw as a spreading element, which is pressed into an expansion element receptacle formed as a widened region of the gap 104 in order to accomplish the widening or wedging.
As shown in FIG. 7, a nail is driven into a spreading element receptacle 118 as a spreading element 120. Here, the engagement elements 108, 114 in cross-section substantially U-shape. The gap 104 may also taper.
Fig. 8 shows a perspective view of a connector 100 according to an exemplary embodiment with double dovetail profile.
Fig. 9 shows a connector assembly 100 which is similar to Fig. 8 but has rounded edges in the dovetail profile.
Fig. 10 shows an arrangement similar to that in Fig. 6, but now the two Ein¬ grip elements 108, 114 are again formed as a dovetail profile, in contrast to the substantially double-U arrangement of Fig. 6.
Fig. 11 shows a similar configuration as in Fig. 10, but again with abgerun¬deten edges.
12a shows a connection arrangement 1200 with a connection element 100 according to an exemplary embodiment of the invention, in which the connection element 100 is not positively locking over the entire area. Instead, a triangular recess 1202 remains on both sides in the top view of FIG. 12a.
Figures 12b, 12c and 12d show connection assemblies 1210, 1220 and 1230, respectively, according to example embodiments of the invention employing non-planar module variants.
Referring to Fig. 12b, a cylindrical module 200 of round cross-section is connected to a cuboid module 202 with a one-sided round recess.
Referring to Fig. 12c, two side-by-side arcuate modules 200, 202 are connected to each other.
Referring to Fig. 12d, two stacked arcuate modules 200, 202 are connected to each other.
The connection system according to the invention establishes a reliable connection between modules of all kinds and can be released again without damaging the module or connecting element. This allows for both reuse of the connectors as well as quick and easy recombination of module parts. Modules, preferably in furniture construction, can thus be interconnected. As an option, this connection can be released at any time and used elsewhere. This results in numerous variations in the arrangement of the individual modules, resulting in a variety of furniture, in particular table, seating, lying, storage and / or bar or shelf furniture and numerous other furniture variants.
In order to provide a releasable connection of two modules by means of a connecting element, the following measures can be taken in particular according to exemplary embodiments.
In the module, at the at least one connection point in each case a ridge be excluded (for example, milled). The ridge strips of two modules to be connected can be arranged logically.
In the connecting element, the connection may preferably be designed as a double bifolium, which is split in the middle. In this gap is, for example, a grub screw with hexagon socket.
As regards the connection, the ridge recesses of the modules to be connected may be designed such that the connecting element fits in with a small clearance. The grub screw is turned by means of an Allen key into the gap of the connecting element. The wedging apart of the connector fixes the modules together. By unscrewing the threaded pin with hexagon socket by means of the Allen key, the connection can be released and then re-used as desired.
In a manufacturing method according to exemplary embodiments, a dovetail (or other shape - approximately round, for example, like bone cross-section) is preferably in the bar with rectangular, square, etc. cross-section with a router first beid¬seitig above and below milled. Then it is cut to the desired degree, the milled strip is now cut in the desired lengths. Now a vertical hole is drilled with a pillar boring machine to prevent later fraying of the center slot then cut to that hole with a circular saw. Then, a hole of 5 mm diameter is drilled along this slot in the center of the connecting cross section with a long hole drilling machine, and then a 6 mm screw is screwed therein, which cuts a thread in the hole. It is alternatively possible to connect to a CNC machine.
The shape of a module may be a wall, a plate, a cube, a cuboid, a rhombus, a bow, a wave, etc. Each module can be solid or hollow. At or near the junction, the modules to be connected should be positively connected.
As the material for the module, for example, wood cubes made of laminated birch plywood can be used. Laminated wood is particularly well suited due to the lower warpage compared to wood with continuous lamella. Other possible materials are rubber, metal, plastic, plastic, glass fiber, rubber, steel, concrete and other materials, in principle, all materials are suitable, in particular all conventional Bauma¬terialien. Other materials are possible.
The connecting element may have various shapes. As an alternative to a double dovetail, rounded shapes such as a bone cross section and other conclusive shapes are also possible. Suitable materials for the fastener are all materials that are elastic enough that a spread is possible. Preferred materials are suitable for milling. Solid wood is preferred if the connection is to be releasable again. In the case of wood, it is preferred that, for releasable connections, the shrinkage dimension of the connecting element is less than or equal to the shrinkage dimension of the module material. For non-releasable connections, the shrinkage of the fastener should be greater than or equal to the shrinkage of the module material.
With regard to suitable dimensions, the connecting element length should be adapted to the module size, weight, etc. For example, the compound is preferably a 10cm (variation measure = VM VM 8cm-15cm) long double dovetail, which is split centrally in the longitudinal direction to a length of 6.3cm (VM 4cm -12cm). In this gap is a 2cm-8 cm long threaded pin with hexagon socket.
Application examples of embodiments of the invention are a kit for children (of correspondingly smaller dimension). In general, all types of furniture or wall connections can be made. For large dimensions, there are applications in facade construction, precast buildings and bridge construction.
For furniture construction, for example, the following combination of the modules (designed as cubes, for example) is possible. The modules are placed on the ridge recess at the ridge recess, interlocked, set or laid. Then the connection is inserted into the aligned ridge recesses and the modules are connected together. If you want to use the modules differently, the connections are solved as described above. The modules are brought into the desired position and fixed together with the same procedure as described above.
In module systems, in one example, the cubes of front and back are outgoing with 8.5 cm - 15.5 cm long horizontal parallel ridge recesses, in the form of simple dovetails each at a constant distance of 7 cm (multiplier: 5, 6, 7 , 8, 9, 10 ...). Of course, many other shapes are possible.
Gratausnehmung: Length: (VM 8.5cm - 15.5cm), width: top VM (1cm- 8cm) bottom VM 1.4cm - 9cm, height 0.8cm (0.2cm - 5cm) angle of 15 degrees (VM 12Grad-20Grad) [00139] During the connection, ridge strips (horizontal ridge recesses in the longitudinal direction with a total length of 10.1 cm - total length of variation of up to 600 cm) are milled into the modules in the form of simple dovetails. The modules are put together and connected by means of the joint, preferably double dovetails in the length of 10 cm (variation measure), width of 2.5 cm (variation dimension of 20 mm to 40 mm), angle of 15 ° (variation measure of 12 ° to 20 °). It is possible to connect both horizontally and vertically.
With regard to the arrangement of the gratings, the gratings are located at the front and back of the modules. In this case, an arrangement grid is selected which allows the highest possible variation of the arrangements of the modules. In general, the module dimensions according to an exemplary embodiment are always a multiple of one another and the connections are always provided at the same intervals in order to ensure a maximum of possible variations of the arrangement.
In order to provide as many connection variants of the modules, the gate recesses are arranged according to an embodiment according to a systematic grid. Similarly, the cubic dimensions follow the principle of multiplication. The width and height of the cubes are always, according to one embodiment, a multiple of 7cm (VM200cm x 200cm or another multiplier 3, 5, 7 etc.).
The open flashings are, according to one embodiment, closed with fillers (for example made of MDF sheet medium density fiberboard, ie medium density fiberboard). These are according to one embodiment, simple Schwalben¬schwänze in a length of 10.5 cm (VM 8.5 cm -15.5 cm). At the top there is a notch (width 8mm -15mm, depth 1mm -5mm, made in round cutout), which allows the manual extraction and insertion of the filler in the ridge recesses.
It is according to one embodiment, a detachable connection of elements. In these elements (for example cubes) ridge recesses are milled in the form of dovetails. In the horizontal ridge recesses of two elements, the double dovetail joint is introduced and clamped and fixed by means of a screw (diameter 6 mm variational dimension), which is introduced into the cut-out gap this bar.
If you want to use the cubes differently, the connections are pulled out by gently turning out the screw and pulling on the screw back from the Kubbenfräsungen. The cubes are brought into the desired position and fixed together with the same procedure as described above.
13 shows two orthogonally adjoining wall surfaces 212, 208 of two modules, which are connected to one another in a connecting region 1300 at mutually perpendicularly oriented end sections of the modules by means of a connecting element 100. Thus, by using the connecting element 100, a detachable connection can also be made Corner are realized.
The configuration of FIG. 14 differs from the configuration shown in FIG. 13 in that, in a connection region 1400, the side walls 208, 212 to be interconnected do not have a right-angled cross-section, but rather a triangular one (more precisely triangular-shaped ) Have end portions that result in juxtaposition of the two side surfaces 208, 212 with touching contact at the triangular end portions to form a generally rectangular body.
Fig. 15 shows a cuboidal module with a hollow interior. In the module according to FIG. 15, a recess 206 is formed in an upper side wall 212, into which a connecting element according to the invention can be introduced, if a corresponding module is attached to the module shown in FIG. 15 such that its two recesses 206 together form a receiving space form, which corresponds to the geometry of the Verbindungsele¬ments.
Fig. 16 shows a similar arrangement as Fig. 15 with the difference that in the upper side wall 212 not only a recess, but two mutually parallel aligned recesses 206 are formed. FIG. 16 further shows that a recess length or length I of the recess 206 in the insertion direction 1600 of the connecting element not shown in FIG. 16 is smaller than a total length L of the side wall 212 of the module shown in FIG. 16 in the insertion direction 1600 , This shows that for establishing a detachable connection between the module shown in FIG. 16 and a similar other module for example, the formation of a connection over the relatively small length I, which is shorter than the length L, is sufficient. In the embodiment shown, I = 1/4 L.
FIG. 17 shows an alternative embodiment to FIG. 16, in which a module embodied as a hollow body has, on an upper side wall 212, a recess 206 which extends over the total length D of the upper side wall 212. A connecting element which is not shown in FIG. 17 may, according to this embodiment, have a connecting element length d shortened in relation to the total length or module wall length D. The connecting element can thus be introduced into the recess 206 only up to the length d in the insertion direction 1600, in particular so that an end face of the connecting element terminates flush with a surface of the side wall 212. It has been found that short connecting sections of length I or d are already sufficient to form a reliable connection between two adjacent side walls 212 and one connecting element.
Further, as shown in Figs. 16 and 17, the required sizes and weights of connecting members are small, so that the arrangement can be made compact and lightweight as a whole. The embodiment of Fig. 16 has the particular advantage that the abutment of the connecting element on the bottom end surface of the recess 206 provides haptic confirmation to a user that the connecting element is inserted to a correct depth. The exemplary embodiment shown in FIG. 17 has the particular advantage of particularly low costs, since a continuous groove, such as the recess 206 shown in the overall length L, can be produced particularly inexpensively.
FIG. 18 shows an alternative to FIG. 1 connecting element 100, which differs from the latter in that the gap 104 gebil¬det only one side of the Spreizelementaufnahme 118. In other words, the lower half of the connector 100 shown in FIG. 18 is free of holes, and only the upper half has the gap 104. This leads to a cost-effective production.
19 shows a further alternative embodiment of a connecting element 100, in which the gap 104 is not aligned vertically to a lower surface of the connecting element 100, as in FIG. 1, but inclined at an angle thereto. For example, the gap 104 shown in FIG. 19 with continuous lines, which extends diagonally through the connecting element 100, is possible. Alternatively or in addition, however, the inFig. 19, dashed configuration of a gap 104 may be implemented.
Fig. 20 shows a connector 2000 according to another exemplary embodiment of the invention in a plan view. Fig. 21 shows the connector 2000 during assembly in a three-dimensional view.
According to the illustrated embodiment, the connecting member 2000 includes a base body having a flat front end face 2002 and a flat rear end face 2004, which are opposed to each other in parallel and perpendicular to an extension in Einführrich¬tung the Spreizelementaufnahme 118. As shown in FIG. 20, the gap 104 extends into the central portion 102 from the rear or rear end surface 2004. In contrast, the Spreizelementaufnahme 118, as shown in FIG. 21, starting from the front end face 2002 into the center section 102. The terms of the front end face 2002, 2004 refer to the orientation of the connection member 2000 in the two-module mounted state of the connection member 2000. In other words, the front end face 2002 is seen to be externally mounted, whereas the rear end face 2004 is in the in-state Inside of the modules is sunk.
For assembly, the connecting element 2000 is inserted into the adjoining recesses of the modules, and then the screw 120 is screwed into a preferably koni¬sches hole 118. On the opposite side widened by the insertion of the screw 120 in the Spreizelementaufnahme 118 gap 104, thus causing the wedging.
In addition, it should be noted that "having " does not exclude other elements or steps and "a " or "a " no multiplicity excludes. Furthermore, it should be pointed out that features or steps which have been described with reference to one of the above exemplary embodiments can also be used in combination with other features or steps of other embodiments described above. Reference signs in the claims are not intended to be limiting.
