    CONNECTION DEVICE
    The invention relates to an attachment of planks to a substructure, in particular patio cover, using a connecting part which rests on a protruding from the longitudinal side surface of planks below partial surface and is connected by a fixing part to the ground, wherein the connecting part under elastic Preload is applied to the planks, wherein the spring constant of the connecting part against forces at the contact surface with the screed is a smaller than that of the screed at this contact surface, and wherein the elastic deformation region of the connecting part is greater than the range of those dimensional changes on the cross-sectional area of the Bohle, which are caused as a result of occurring in normal use temperature and humidity fluctuations. The most important application for this is the formation of floor coverings outdoors, for example terrace coverings.
    Planks in this sense are rods, profiles or elongated boards, which typically consist of wood or wood-plastic mixtures. To form a cover they are mounted parallel to each other, with a small lateral distance from each other, on a substructure, usually in the form of a transverse battens.
    A common method to attach the boards to the substructure is to screw them by a screw or a nail from the Qberseite the planks ago, or nailed. The advantage of this method is that it is easy to use and that except screws or nails no fasteners are required. Disadvantages are the disturbing visibility of the heads of the fastening parts, that the planks lie directly against the substructure, whereby creeping moisture can last long and thus have a destructive effect, as well as the lack of possibility, the moisture-related and thus quite natural swelling and shrinkage behavior of the wood or wooden planks.
    According to DE 298 23 195 Ul and EP 1 106 842 Bl planks are used, which are provided at their Längsseltenflächen with a groove. The planks are held by attachment point, which are fixed in the gap between two planks by screws to the substructure and lay with lateral projections on the lower groove flanks of the adjacent planks. Disadvantages of this simple attachment method are in turn the risk of destruction by creeping moisture, since the planks rest directly on the substructure, and the lack of ability to compensate for dimensional changes of the planks as a result of swelling or shrinkage. Due to these dimensional changes, it may happen that the planks bulge inadmissibly upward when swelling, or the attachment site can not withstand the enormous pressure. When shrinking on the other hand planks can become so loose that they rattle inadmissible and can be displaced in the longitudinal direction.
    According to DE 102 30 797 AI a fastening part is used, which has the shape of a low, upside down T. It extends in the gap between two adjacent planks and below them. With the lower surface of the fastening part is attached to the battens, from the central bridge tips stuck in the side surfaces of the boards and thus fix them. A disadvantage of this attachment is that for their production a special tool is required to push the tips into the planks and that they are provided with such boards in the side with a groove can not be applied. The attachment can also not or only with great difficulty be applied if the planks of very brittle woods or other materials with similar strength properties, since then the tips of the fastening part can not be easily pressed into the side flanks of the planks. By the construction also no dimensional changes of the planks can be compensated.
    According to the documents US 4,296,580 and US 4,844,651 extend flat
    Areas of connecting parts between the planks and the substructure. The attached to a longitudinal side of a screed connecting parts are also connected to the substructure, typically by a screw. Due to the split construction, the mounting of the fasteners is a little easier. The disadvantage here is the risk of creeping moisture, and the impossibility to compensate for dimensional changes of the planks.
    The inventor has set itself the task to provide a connection between planks and substructure, in which no parts of the compound protrude from the gap between two planks, wherein the planks are kept at a small defined distance from the substructure, the planks be defined and kept free of play even if they change their mass by swelling or shrinkage slightly in the course of their use and the insertion or removal of planks is facilitated.
    As additionally desirable, it is stated that replacement of damaged planks should be as simple and quick as possible, and that the planks can be turned if so desired that the previous, protected bottom, to the, the weather more exposed top is , Of course, the connection should be inexpensive to manufacture both from the material and from the work.
    The object of the invention is achieved in particular by the combination of features of the independent claim.
    To solve the problem is - as in known constructions also - to use such profiled planks, that the mutually facing surfaces of two adjacent planks have a groove extending in the longitudinal direction of the plank. A connecting part extends in the gap between two adjacent planks, protrudes on both sides with a lateral extension in the groove of the planks located there, and is located with this extension to the lower groove flank. By one or more screws or similar fasteners, the connecting part is vertically penetrated approximately in the center plane between two planks and connected to the substructure. As an improvement over the known prior art, it is proposed to form the abutting on the planks lateral extensions of the connecting part so welch, far and temporally lasting elastically deformable and pretension during assembly accordingly, that they the size changes that the planks due to temperature or undergo moisture changes, can participate, and always rest under compressive stress on the planks. There are several ways to produce this elasticity by constructive measures. Important basic principles and advantageous further developments can be understood by the drawings and the more detailed description that follows: FIG. 1: shows the fastening according to the invention during installation in a vertical sectional view, the sectional plane lying normally on the longitudinal direction of the planks. The arrow shown in the left part of the picture symbolizes the direction of movement of the screed during the assembly step shown.
    Fig. 2: shows the connecting part of Fig. 1 from above.
    Fig. 3 shows a fastening according to the invention with the connecting part of Fig. 1 during disassembly of a centrally located screed (for example, to replace a single faulty screed) in a vertical sectional view, with the cutting plane normal to the longitudinal direction of the screeds.
    Fig. 4: shows a second embodiment of a Verbindungsstei les invention, wherein the viewing direction is parallel to the longitudinal direction of the planks.
    The located between two facing surfaces of two adjacent planks 1 connecting part 3 projects on both sides with a lateral extension 3.1 in a groove on the adjacent side surfaces of the screed 1 and is located with this lateral extension on the lower edge of this groove. The downwardly projecting partial surface 1.1, which forms this lower flank of the groove on the screed 1, is inclined. As can be clearly seen in the left part of FIG. 1, the extension 3.1 of the connecting part 3.1 brought into contact with this partial surface 3.1 is formed in a relaxed state in such a way that its lower surface is slightly less inclined, the partial surface 1.1, and the upper one End of the lower surface of the extension 3.1 is located in the height range between the lower and upper end of the part 1.1 of the screed. If, during assembly, the screed 1 is pushed towards the connecting part in the direction parallel to the plane of the substructure 2, therefore, the extension 3.1 of the connecting part 3 is bent upwards on the downwardly projecting surface 1.1 of the screed and then lies under elastic prestressing on this surface at. The connecting part is typically made of a strong but permanently elastic plastic.
    The described bending up of the two extensions 3.1 when pushing the planks can be substantially facilitated if the lying between the two extensions of the connecting portion 3, ie that on the plane parallel to the plank direction symmetry plane is weakened so that it is about an axis , which is parallel to the planks, can be easily bent. This can be done, for example, by the well-visible in Figure 2 row of holes, which extend from holes 3.5 in said plane of symmetry vertically through the connecting part happen. Compared to the relaxed state, the area at these holes when pushing the planks is deformed by the high pressures of the extensions. The upper part of the cross-sectional area of the holes 3.5 is compressed transversely to the board direction, the lower part may be stretched. As a result, an enlargement of the length range is achieved compared to an unattenuated connecting part, in which the connecting part 3 can deform elastically to compensate for width variations of the planks.
    The connecting part 3 is fixed by screws or nails, further referred to as fastening elements 4, to the substructure 2. The fasteners 4 penetrate the connecting part 3 in its vertical direction parallel to the plank longitudinal direction vertical plane of symmetry through holes 3.5 vertically. The region of the connecting part 3, to which the widened compared to its other longitudinal area head 4.1 of the fastening element 4 comes to rest, is claimed by the previously described bending deformation of the two extensions 3.1 when pushing the planks 1 to pressure. When the ideal, downwardly conically narrowing head 4.1 of the fastening element 4 is sunk during assembly in the holes 3.5 on the connecting part, there material is displaced against the action of the bending deformation described above. It is thus possible to design the connecting part and fastening part such that, when the fastening part is not fully tightened, the planks 1 can be pushed into the final position on the connecting part 3 without great effort, but that when the fastening part 4 is brought into its final position, the connecting part 3 exerts on the planks an advantageously larger and lasting holding force. A well-functioning dimensioning of the connection part can be easily found by a multiple iterative process of approximation, trial and correction. By varying the geometry of the fastening part can thus increase the range of application of the connecting part.
    Of course, other methods than attaching a row of holes are conceivable to make the connection part in its plane parallel symmetry plane well bendable. For example, you can provide the connecting part in this area with a parallel plank groove, and provide only one or two holes for the required implementation of a fastening part.
    Here, the important for the fixation of the planks, horizontally extending projections 13.1 of the connecting part 13 are formed as part of a extending in the longitudinal direction pylon hollow profile. Vertical is the fastening part and thus also this hollow profile with through holes 13.5 provided for fasteners. By attaching the fasteners (screws or nails), the hollow profile is pressed flat, ie lower and wider. Compared to a construction of the connecting part 3 according to FIGS. 1 to 3, the one-time, simpler dimensioning process is confronted with a higher production outlay with each piece produced, since the connecting part 13 can not be manufactured so easily as an injection-molded part. The contact surfaces of the connecting part 3 with the planks 1 according to FIG. 1 to 3 are executed toothed. That is, the connection part rests against the planks only with the tips of the teeth 3.3. Between the individual tooth tips run groove-like depressions on the surface of the screed does not come to rest. These groove-like depressions also form channels in the installed state, through which moisture can flow away and moisture can dry off. Especially when the profile shape of the teeth 3.3 is tapered from the base to the top, for example, triangular or trapezoidal, thus additional, desired elastic deformability in the contact surface between the connecting part and planks is achieved. Ideally, the profile direction of the individual teeth 3.3, or lying between them channels normal to the longitudinal direction of the planks. 1
    It is advantageous to form the connecting part of two material components, wherein a material component is substantially stiffer than the second component and this softer component is attached to the contact areas to the planks. This ensures that the planks fit better, and it is in turn increased the range in which dimensional variations of the planks can be compensated. The increased parts costs of the connecting part are to be counted against the benefit in individual cases.
    Another measure to avoid damage due to moisture is to provide the connecting part 3, 13 with a foot section 3.2, 13.2, which protrudes under the underside of the screed 1, and on which the screed 1 rests. This prevents the screed and substructure from touching each other directly.
    By using an elastically deformable material for the connecting part 3, 13, despite the presence of a foot region, which protrudes below the plank underside, individual planks, which are mounted according to the invention amid other planks, solve individually from this composite. That if you want to remove a single plank in the middle of a surface, you do not need to loosen all planks from one edge of the surface until you get to the one plank. To release a single screed in the middle of a composite surface consisting of planks, substructure, connecting part and fastening parts, the fastening parts are solved at the connecting parts on one side of the screed. Then the two adjacent to the dissolved connecting parts planks are raised with slight rotation about the undone connection parts on the other longitudinal side of the planks until they are released (Figure 3). The dissolved connection parts are thereby lifted with, and her foot area 3.2 is bent relative to its central part down. This bending can be substantially facilitated if a groove-like recess 3.4 running parallel to the plank direction is provided on the foot region, at which the cross-sectional height of the foot region is locally reduced.
    The insertion of a screed in the middle of a composite takes place in reverse motion sequence. Of course, all under mechanical stress solids are elastically deformed and within a certain range also further elastically deformable; as well as previously known connecting parts. The connecting parts according to the present invention differ from previously known connecting parts in that, at the contact points with the planks, the elastic deformations due to the contact forces with the planks are greater than the elastic deformations on the planks due to these forces. In other words, it means that the spring constant of the connection parts against forces on the contact surface with the planks is smaller than that of the planks. The spring constant in this sense is the quantity with which a length measurement change must be multiplied in order to calculate the force which causes this length dimension change by elastic deformation. Furthermore, it is important for the connecting parts according to the invention that the range of elastic deformability is so great that the dimensional changes of the planks and the substructure as a result of temperature and humidity changes can be compensated for. That the elastic shape changeability of the connecting parts according to the invention in the relevant masses is typically of the order of magnitude in the millimeter range.
    In addition to the shapes shown, there are certainly a variety of other possible shapes and material combinations for connecting parts, so that they have the required softness, size of the elastic deformation range and strength. The forms shown are merely illustrative and advantageous embodiments of the underlying idea.
    With the direction designation "bottom" is meant in this description and in the claims that direction in which the connection part 3, 13 of the substructure 2 is located. Of course, the invention is not only applicable to applications in which the substructure in terms of sea level below the connecting part - ie in soils - but also, for example, in applications for wall or ceiling paneling.
