Description

(1.) DESCRIPTION

[0001] The panel construction system described in claims 1 to 20 is a surface structure. It is self-supporting, meaning it does not require a structurally supporting framework in which the panel elements merely serve as infill. The static loads existing within the system are transferred directly from surface to surface via the assembly elements, utilizing the stability of the panel elements. (1.2) STATE OF THE ART

[0002] The invention characterized in claims 1 to 20 is a snap-fit ​​connection. One snap-fit ​​principle, found in many variations, is the cantilever or cantilever snap-fit ​​connection. These also exist as flexible, U-shaped, or L-shaped snap-fit ​​connections, in which the hook-shaped cantilever of one component snaps under the undercut of a second component, thus connecting them. Alternatively, the cantilever is designed like a two-thirds open round clamp and can be snapped onto a round profile. They are almost always injection-molded plastic parts and are used, for example, in consumer electronics, product housings, lids, packaging, and clamp-like closures. All these snap-fit ​​connections have low load-bearing capacities. Ring-shaped snap-fit ​​connections, for example,Snap-fit ​​connections, used in containers, bottle caps, and even in the automotive industry for ball joints, are more durable but difficult to disassemble. Most snap-fit ​​connections are characterized by the fact that they can only be installed in one direction.

[0003] Most of the known panel building systems are fixed by their mounting points in the angular position of the panel elements relative to each other, so that their variability is tightly determined, or they require differently positioned mounting elements for each panel element added in the same edge axis. (1.3) PROBLEM

[0004] The invention described in claims 1 to 20) is based on the problem of developing a panel construction system that comes close to the ideal that several panel elements can be variably connected in a common axis, along their edges, at any angle to each other, as easily as possible and just as easily detachable. (1.4) SOLUTION

[0005] This problem is largely solved by the invention characterized in claims 1) to 20). (1.5) BENEFITS ACHIEVED

[0006] An advantage of the invention is its good load capacity, since the ring shape of the disc edge (2), which is homogeneously connected to the flange disc (1) and sleeve (5) and is designed as an undercut, withstands high tensile loads and the sleeve (5) of the double flange sleeve ( Fig. 1) high, opposing pressure loads.

[0007] The edge clamp is also very durable ( Fig. 2), since their undercut edges (8) with a large material thickness engage under the undercut edges of the flange disc edges (2) when the double flange sleeve ( Fig. 1) is pressed in.

[0008] A very significant advantage of the invention compared to known snap connections is that the mounting direction of the plate elements ( Fig. 5) into a mounting point ( Fig. 3) is possible not only towards the connecting axis, but also perpendicular to it, because the edge-open V-shape of the edge clamp edge ( Fig. 2) compared to the plate shape of the double flange sleeve ( Fig. 1) a lateral indentation of a plate element ( Fig. 5) permitted. For example, when constructing a cube shape with this panel system, it is also possible to use the last panel element ( Fig. 5) to assemble by simply placing it perpendicular to the plate elements already joined together ( Fig. 5) is pressed in until it finally snaps into the correct position.

[0009] A significant advantage of the invention compared to known panel construction systems is that several panel elements can be positioned at free angles to each other ( Fig. 5) at the mounting points ( Fig. 3) can be connected to each other along a common edge axis, thus allowing for great design freedom, even up to the construction of polyhedra and domes.

[0010] Furthermore, the simple and quick assembly and disassembly of this panel construction system is a great advantage, without having to carry out additional work or need tools.

[0011] One advantage is that the edge clamps ( Fig. 2) must only be installed once all the other panel elements ( Fig. 5) the relevant work has been carried out, so that there are no obstacles to this work, e.g. raised areas.

[0012] Another advantage of the invention is that various panel materials, such as MDF, plywood, joinery, or particleboard, as well as plastic and even cardboard panels, can be used. The system components include the edge clamp ( Fig. 2) and double flange sleeve ( Fig. 1) only need to be adapted in their dimensions, and the introduction of the required edge profiles and point surface penetrations ( Fig. 5) for mounting the edge clamps ( Fig. 2) must be possible.

[0013] It is also particularly advantageous that different surface modules can be combined, such as squares, rectangles, equilateral or right-angled triangles, pentagons, hexagons, etc., so that even polyhedral bodies are among the design possibilities of the invention.

[0014] An advantage is that the system components of the invention are simple and inexpensive to manufacture and to obtain materials for; for example, the edge clamp ( Fig. 2) and the double flange sleeve ( Fig. 1) uncomplicated injection-molded parts and also the materials of the plate elements ( Fig. 5) can be very inexpensive compared to other prefabricated building systems.

[0015] A particular advantage of the invention is its hinge function, which allows it to be used for a wide variety of applications. (1.6) POSSIBLE COMMERCIAL APPLICATIONS

[0016] The invention can be used and deployed, for example, as a trade fair construction system, as a partition wall system for advertising and information, as a space-defining polyhedral system, and even as a construction toy for children and daycare centers. Numerous applications are also conceivable as a hinge, for example, when pivoting surfaces need to be easy to assemble and disassemble. (1.7) FURTHER EDITING OF THE INVENTION

[0017] The inventive principle can also be designed for higher loads; for example, a variant would be possible in which both connecting components are made of metal, with the flange discs (1) having internal threads and the sleeve (5) having external threads in the edge clamp ( Fig. 1) are twisted apart and thus connect to each other in a form-fitting manner.

[0018] One variant of the invention is to modify the edge profile of the edge clamp ( Fig. 2), which connects to the double flange sleeve ( Fig. 1) allows milling or laser cutting directly into the edge of the panel (10), which, however, significantly increases the quality requirements for the panel material.

[0019] An obvious variant of the invention is to use the double flange sleeves ( Fig. 1) to connect them together using rods or tubes in order to close the system-related gaps between the panel edges (10) and thus improve the appearance of the panel building system. This would open up the possibility of laying electrical cables, e.g. for lighting the system, etc., in a protected and concealed manner.

[0020] To close the gap between the plate edges (10), a thin lip or strip can also be inserted around the plate edges (10) and through their center, extending to the central axis of the double flange sleeve ( Fig. 1) is sufficient, the edge brackets ( Fig. 2) sparing.

[0021] Including the system variants and configurations described here, the principle of the invention as defined in claims 1) to 20) and illustrated in the drawings remains. The claim nevertheless expressly extends to all variants and configurations of the invention described here and any further possible variants and configurations.
