    toy building
    BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a toy building element in the form of a box-shaped hollow body defined by an upper surface and associated transverse sidewalls, which has a protruding primary coupling means with predetermined contours and location patterns, and wherein the box-shaped cavity body has secondary coupling members. , which is adapted to cooperate with primary coupling means on a neighboring element in a number of frictional regions.
    For example, a building element of this kind is known from US 3,005,282.
    This well-known building element from a world-renowned manufacturer was later developed and patented with great success. It is contemplated that the primary coupling means provide a frictional coupling to the side walls of the element and inner coupling tubes, the frictional coupling being based on the elastic resilience of the walls. Any elastic deformation results in cold deformation, which in the long run will cause the coupling force to become looser and looser with time. This is sought to be avoided by the prior art by using high quality plastic types. In the prior art, sufficient wall thickness is also required to obtain sufficient coupling power, and finally, high demands are made on the accuracy of the casting tools to achieve a well-defined coupling force.
    Taken together, this prior art, which is based on frictional force, involves high production costs and a limited frictional force, ie, limited coupling force.
    The object of the invention is to provide a toy building element which exhibits greater coupling force than the known elements, and in which the coupling force also remains unchanged for the life of the element. One object is also to ensure a compatibility with the known elements. A further purpose is to be able to reduce the requirements for plastic quality and tolerances.
    in
    DK 2016 00454 A1
    This object is achieved by the fact that the primary coupling means comprise primary locking means and that in the box-shaped hollow body there are secondary locking means, whereby the primary locking means are arranged for snap-locking interaction with the secondary locking means on a neighboring element in some locking regions located outside said areas of friction, and wherein the secondary locking means are resiliently resilient in directions parallel to the upper side of the building element.
    The snap lock according to the invention supplements or replaces the frictional force, and therefore reduces the requirements for plastic types, wall thickness and the accuracy of the tools, thereby making the element cheaper to manufacture. Because of the wide spread of the known elements, it will be a significant advantage that the element according to the invention is compatible with the known elements, and this is achieved by the locking regions being located outside the friction areas.
    The invention thus results in a combinatorial effect, namely that the elements can be made cheaper, exhibit greater coupling power and be interconnected with the known elements. In addition, there are a number of other benefits that will be discussed below.
    In a preferred embodiment, the secondary locking means are generally elastically relieved in the snap-lock position. Thus, materials are not loaded in the locking position, thereby eliminating the risk of cold flow, so that the least possible requirements for the plastic type are made.
    In a preferred embodiment, the secondary locking means are located on the inner side of the side walls of the hollow body. Preferably there are also coupling tubes in the hollow body, where the coupling tubes according to the invention are provided with secondary locking means.
    The elements of the invention may be injection molded, but also suitable
    3D manufacturing. Plastic types that are most suitable can be used
    DK 2016 00454 A1 for 3D production without the risk of a bad building experience due to cold flow. 3D fabrication is a rapid development technology and the element of the invention is also suitable for fast 3D fabrication as, as stated above, less demands are made on both wall thicknesses and accuracy.
    Environmental concerns are gaining more and more attention. In the context of toy building elements, it may be substances in the plastic that are harmful to the children, or it may be the disposal of the elements, or a raw material / oil problem in connection with the manufacture as well as the production price. According to the invention, great freedom is obtained in the choice of plastic types, so that environmental considerations can also be prioritized.
    In a preferred embodiment, at least some of the primary coupling means are defined by an octagon. By providing the primary locking means on the octagonal plate outside the inscribed circle of the octagon, it is achieved that the locking means do not prevent the friction clutch and that friction clutches do not prevent the snap lock function. It is emphasized that the invention is not limited to the octagonal plate. Other forms may also occur when the snap locks do not overlap the frictional regions.
    Because the octagon shaped plate is coherent with the building element via ribs which extend across the upper side and located next to a respective friction point, the least possible material consumption is obtained and partly that it is simple to manufacture a casting tool.
    In one embodiment, when the ribs align with the inscribed circle of the octagon, frictional force may be provided between the ribs and the elastic sidewalls or coupling tubes of the element.
    The secondary locking means can be made resiliently resilient in a number of ways, but in a preferred embodiment, the secondary locking means comprise projections which are connected to a wall which is
    DK 2016 00454 A1 resiliently resilient in directions substantially parallel to the upper side of the element.
    In addition to the advantages already mentioned in the invention, another problem is solved by the prior art, namely that there is a close connection between the forces that must be used to assemble the elements and to separate the elements again. In many applications, it is desired that greater forces are needed to separate the elements than to assemble them. This is achieved according to the invention in that the locking projections have engagement surfaces with respective engagement angles with respect to the wall supporting the locking projection, where the angles define respectively the on and off force.
    As mentioned, the element according to the invention is compatible with known building elements based on frictional force. Therefore, the invention also includes variants having one or more rows of primary coupling means and corresponding internal coupling tubes or coupling walls. In the case of coupling walls, the compatibility is supported by the coupling wall according to the invention having both an area for frictional coupling and one or more locking projections to the side of the friction area. In the case of coupling tubes, the compatibility of a preferred embodiment is supported by the fact that the coupling tubes of the invention are octagonally shaped in cross-section and that the secondary locking means are outside the inscribed circle of the octagon while the frictional regions are flush with said circle.
    In one embodiment of the invention, there is a housing space on the upper side of the primary coupling means, the contour of which corresponds to a secondary coupling tube in a downsized neighboring element such that the coupling tube is accommodated in the cavity in the coupled position of the elements. This feature is a further compatibility measure which ensures that a primary coupling means according to the invention can be coupled to a coupling tube in a neighboring element which is cut down, as is known, for example, from elements with the trademarks DUPLO® and LEGO®, respectively.
    DK 2016 00454 A1
    Thus, it will be appreciated that the element according to the invention is to a large extent comparable with elements having said product names.
    The invention is an ideal adaptation to the technique of the future, namely 3D production. This is due to the already mentioned low demands on accuracy, plastic quality and material (consumption. And since the element according to the invention is comparable to the known elements, the children can still use the known elements together with the elements according to the invention, and feel as long as the frictional force of the known elements are sufficient to provide a good building and play experience.
    From US 2014244018, it is known that children will be able to face even greater creative challenges by being able to design their own building elements using 3D technology. This opens up countless new designs for assembly with well-known building systems. But in practice, these new opportunities can cause problems for the children. This can happen, for example, if elements are designed where a good play experience assumes that the coupling force holding the elements together is greater than can be achieved with the known building elements. In the present invention, the coupling force can be adapted to the loads to which the structure is subjected.
    For example, advanced static structures and structures incorporating mechanical transmission, where a high torque places high demands on the elements not being separated during play.
    This can be avoided according to the invention in that the inclined surface of the locking projection, which fixes the elements among themselves, forms a large angle with the sidewall of the element and gives a substantially greater cohesion force than can be obtained by ordinary function coupling.
    The invention is also well suited on a larger scale, for example to build playhouses, where the elements can be wall-mounted and where locking members
    DK 2016 00454 A1 ensures that the playhouse does not fall apart.
    It should be mentioned, for good measure, that snap-lock function in itself is not new in relation to toy building elements. For example, from US 2015004871 a separate assembly bush is known, which is designed to be able to link a 3D manufactured element with other elements. However, the 3D fabricated element cannot be directly coupled to the other building elements, as is possible in the invention.
    The invention will be further explained in the following description with reference to the drawings, in which:
    Fig. 1 shows an embodiment of two elements according to the invention, in which some of the upper element is cut away to show the secondary locking means according to the invention,
    Fig. 2 shows an enlarged section of the same as Fig. 1,
    Fig. 3 shows an enlarged section, but now in the interconnected position of the elements,
    FIG. 4 shows the coupling of a known element with an embodiment of an element according to the invention,
    Fig. 5 shows another embodiment of the invention,
    FIG. 6 shows a partial section through a third embodiment of the invention,
    Fig. 7 shows a partial section through a fourth embodiment of the invention, while
    FIG. 8 shows a vertical section through Fig. 7 along the line VIIf-VliI
    DK 2016 00454 A1
    In FIG. 1 shows an embodiment of two elements i and 2 according to the invention. The elements are shown in a mutual position so that they can be interconnected by sliding them together (vertically in Fig. 1). Parts of the element 2 have been removed so that the locking means according to the invention can be seen and will now be described. Later, it will be explained how the element according to the invention can be coupled to a known element via friction coupling.
    Elements 1 and 2 each have two rows of coupling pins, the outermost of which has reference numerals 3,4,5 and 6. The elements, for example 2, are a hollow body defined by an upper side 8, two side walls 9 and 10 and two end walls, where one end wall 11 can be seen on element 1. in the hollow body there are a plurality of coupling tubes, the element 2 having a single coupling tube 7.
    In FIG. 2 shows an enlarged section of FIG. 1. On the inside of the wall 10 there are two ribs 12 and 13 respectively, each provided with a locking projection 14 and 15. The pipe 7 is octagonal in cross section and has on its four faces other locking protrusions, of which the projections 16 and 17 are shown. in FIG. 2. The cube pin 3 comprises an octagonal top plate 18, and below the top plate the cob pin has a cross-shaped cross section where the walls 19, 20 and 21 are visible.
    The octagonal top plate 18 has eight equal side surfaces 18 ah, of which the side surface 18e aligns with the surface of the tube 7 which carries the locking projections 16 and 17, while the side surface 18h aligns with the side edges of the ribs 12 and 13 supporting the projections 14 and 15, respectively. .
    In FIG. 3 shows an enlarged section of the parts of FIG. 2 when the elements are assembled. The walls of the tube 7 'and the side walls 9,10 of the element are resiliently resilient so that the elements can be compressed to the one shown in FIG. 3 where the locking projections 14 and 17 cooperate with the lower edge of the top plate 18 with snap locking effect. Similarly will
    DK 2016 00454 A1 others, including the projections 15 and 16 (Fig. 2), snap locks under other places of the top plate, and corresponding to the other coupling pins and coupling walls.
    In one embodiment of the invention, the resilient walls and tubes are completely relieved of the snap-lock position, which ensures that the material can be cold flowed in the locking position. In another embodiment, the snap lock can be supplemented with a friction clutch, the side faces 18e and 18h being pressed against the tube 7 and rib 23, respectively, and correspondingly to the other cooperating surfaces.
    In FIG. 4 shows a known element 24 for coupling with an embodiment 25 of the element according to the invention. The known element 24 has circular coupling pins, for example 26 and 27, where the coupling pins are out-core (see later).
    It will be appreciated that the circular coupling pin 26 may frictionally interact with the coupling tube 7a in an area around the one shown in FIG. 2 for the purpose of friction coupling, the side wall of the element is advantageously provided with an additional rib 23 (Fig. 2) which is located between the ribs 12 and 13. The same applies to other cooperating friction areas, so that an element according to the invention can be coupled together. with a known element via friclion cubing. The friction coupling assumes that the elastic walls are slightly deformed in the coupled position.
    It will therefore be appreciated that the element according to the invention can cool slightly if it is coupled to the known element for a long time. This will be particularly pronounced if a cheaper plastic is used. However, this does not prevent the snap-lock clutch of the invention from still being able to provide a safe connection, even though the plastic is deformed quite a bit, because the snap-lock principle of the invention is very tolerant of the targets critical in frictional coupling of the known elements . For friction coupling between known elements it is therefore necessary to use expensive plastic material, and much of it must be used because the walls must be
    DK 2016 00454 A1 thicker. And finally, there are great demands on the tolerances on the manufacturing tools. Since elements of the prior art are produced in large quantities, it will be appreciated that the invention results in enormous savings while increasing the coupling power. According to the invention, the coupling force can even be increased by separating the elements relative to when they are assembled (see the later explanation of Fig. 8).
    The cut-out knob 26 or 27 of the known element 24 has the special advantage that the knob can receive a round coupling pipe from a scaled-down building element, as is known, for example, from the interconnection of two different types of building elements known under the trademarks or DUPLO®, respectively. and LEGO®.
    In FIG. 5, an embodiment of the element 28 according to the invention is shown, in which the coupling pins are cut out, such as the coupling pins 26 and 27 are in fig. 4. The figure also shows how, for example, the ribs 29 and 30 snap in under the top plate 31, while the rib 32, which has no locking protrusion, can frictionally engage the top plate 31, or similarly to the round coupling knob, eg 26 in FIG. 4. The same applies to all other interacting coupling parts. From FIG. 5, it is also possible to sense how much plastic can be saved in the manufacture of the elements according to the invention, which makes it correspondingly cheaper and faster to manufacture them.
    Initially, it has already been explained how many other advantages are obtained by the invention when combined with 3D manufacturing. It will not be repeated here, but in the following, with reference to FIG. 6, 7 and 8 some further perspectives of the invention are explained.
    FIG. 6 shows a section through an embodiment of the element 33 according to the invention, parallel to the upper side. The element is of the type having a single row of coupling pins, and the figure shows the octagonal shaped
    DK 2016 00454 A1 coupling pin 34 on an underlying building element which is connected to element 33. The inscribed circle 35 of the octogon is also shown.
    The reference numerals 10a, 12a, 13a, 14a, 15a and 23a in FIG. 6 can be compared with the corresponding reference numbers (without index) in FIG. 2, and it will be appreciated that there are correspondingly interacting parts on the inside of the side surface 36 and the end surface 37, respectively. Known building elements with a single series of coupling pins usually have only coupling pins in the hollow body, but in a preferred embodiment of the invention there are transverse walls. , e.g., 38 and 39, which are resiliently resilient and provided with locking projections 40 and 41 adapted to snap-lock against the underside of, e.g., the top plate 18 of FIG. 2, preferably such that the transverse wall 38 is resiliently tensioned in the interconnected position.
    The inscribed circle of the octogon corresponds to a coupling pin on a known element adapted for friction coupling. It can therefore be understood that friction coupling can be provided on the wall 38 midway between the locking projections 40 and 41, as well as on the ribs 23a and correspondingly on the walls 36 and 37. This means that as long as the locking means are located outside the circular 35 inscribed circle 35 , the locking means according to the invention and the friction couplings according to the prior art will not collide with each other, thereby ensuring the compatibility between the elements according to the invention and the known elements.
    In FIG. 7, a section is shown through an element with several rows of coupling pins, typically two rows. The reference figures in FIG. 7 with index b can be compared with the reference numbers with index a in fig. 6 or without index in fig. 2.
    The difference from FIG. 6 is first and foremost that the element now has secondary coupling tubes 7b arranged to cooperate with a coupling pin on a neighboring element. In the forertine embodiment of the invention, the coupling tubes 7, 7b are in cross-section octagonal, and the locking projections
    DK 2016 00454 A1
    16b and 17b are positioned outside the inscribed circle 45 for the outer contour of the octogenic coupling tube 7b. This causes the element to
    FIG. 7 may provide frictional coupling to a known element of cross-sectional circular coupling tubes In the region 22b of Fig. 7. the contact line of FIG. 2).
    In FIG. 7, similar to FIG. 6 shows an underlying octagonal coupling pin for coupling with the element shown in section in FIG. 7, cf. the section of FIG. 8, At 19b, 20b and 21b, dashed lines show ribs corresponding to ribs 19, 20 and 21 of FIG. 2. It will be appreciated that the end edges of the ribs may co-frictional with the ribs 23, 23a, and 23b and correspondingly or / and with a known coupling pin in a circular section.
    Thus, the element according to the invention can be combined with other elements of the same or of a known type, where the extent of frictional force can be controlled. In the event that friction is not desired, the latter cooperating ribs may only have a fixing function in directions parallel to that of the element. the upper side.
    The FIG. 7 illustrates how an element according to the invention can be coupled to a known element via friction coupling, or to another element according to the invention via a snap coupling, or via a combination of these coupling principles. As explained in connection with Fig. 6, this is achieved by the snap-locking means of the invention cooperating outside the areas where frictional coupling can be provided.
    Fig. 8 shows a vertical section VIU-VIII through fig. 7. The one locking projection on the wall 37b is shown at 42, and it has two inclined faces 43 and 44.1, respectively, of the coupled position shown, the locking face 43 interacts with the lower edge of the top plate 18b, which corresponds to 18 in FIG. that the surface 43 is more steep than the surface 44 (relative to the wall 37b), which means that it is easier to interconnect the elements than it is to separate them.
    DK 2016 00454 A1
    In Fig. 8, it is noted that there is a very small distance between the top plate
    18b and the side wall 37b. This is to emphasize that the coupling shown is based solely on snap lock coupling. In the event that this is combined with frictional coupling, the top plate 18b would extend all the way to the side wall 37b which would be elastically biased against the top plate.
    It has been emphasized above that the invention is also forward-looking in 3D manufacturing, but it is important to note that the increased holding power is equally relevant in connection with known injection molded elements which must be assembled into a model that is critical in some places. regarding the danger of the model breaking. This can also be expressed so that the increased holding power of the element according to the invention opens up new possibilities for the children's / designer's imagination while allowing the children to use their old, ie known friction coupling elements elsewhere in the model which are not critical with respect to the coupling force.
    Also, the reduced consumption and low demands on the quality of plastic material reduce the manufacturing cost, even for injection molded elements according to the invention. And finally, it should be added that the injection molding tools for the element of the invention are very inexpensive to manufacture. Partly because of the lesser requirements for tolerances and partly because the octagonal plate can be manufactured without special extracts due to the ribs (19, 20 and 21) and the core can be pulled out over the locking projections, because the walls can become elastic as the outer mold is retracted before the inner mold. The element of the invention is simple to manufacture.
