Description

[0001] The invention relates to a frame construction, in particular for trade fair construction, with at least one first basic profile, at both ends of which a side profile is arranged, which side profiles are connected to each other via corresponding first and second connecting parts.

[0002] Frame structures are used, for example, in trade fair construction, primarily to create partitions in the form of walls. Besides frame structures where panel-like wall segments are enclosed within the frame, frame structures are also used to stretch flexible, flat elements, especially textiles, to form a wall. These textiles can be printed or unprinted. The latter has the advantage over rigid wall segments that they are not only easy to transport, but also, and more importantly, easy to assemble and replace once the frame structure is erected.

[0003] Such a frame construction comprises several profile elements that are connected at angles to form a wall segment. Corner connectors are typically used to join two such profile elements; these are attached to or within the profile elements using screws. Corresponding longitudinal connectors are used to join two profiles lengthwise; these are also screwed to the profiles being joined. The assembly of such a frame construction therefore requires numerous screw connections, resulting in considerable effort.

[0004] The invention aims to remedy this problem. The invention is based on the objective of providing a frame construction that enables easier assembly. According to the invention, this objective is achieved by a frame construction with the features of the characterizing part of claim 1.

[0005] The invention provides a frame construction that enables simplified assembly. By comprising a first magnetic snap-fit ​​connection element with a spring-loaded locking element in the first connecting part and a second magnetic snap-fit ​​connection element in the second connecting part, wherein the second magnetic snap-fit ​​connection element includes a locking piece with a detent projection by which it can be mechanically locked to the first magnetic snap-fit ​​connection element, tool-free assembly of the frame construction is achieved. The locking piece of the second snap-fit ​​connection element is magnetically moved into the spring-loaded locking element, thereby creating an "automatic" positive-locking connection.

[0006] Alternatively or additionally, at least one base profile and / or one side profile may also have at least one first magnetic locking connection element and / or one second magnetic locking connection element for mechanical locking with a first or second magnetic locking connection element arranged on a further frame construction or another component.

[0007] The terms "profile" and "base profile," "side profile," "top profile," and "web profile" are to be interpreted broadly in this context. They encompass any elongated components of a frame structure, regardless of material or cross-sectional shape. In exhibition stand construction, aluminum profiles are particularly common, such as strut profiles, grooved profiles, and hollow chamber profiles. Such profiles, especially those manufactured using extrusion, are also referred to as machine tool profiles.

[0008] First and second magnetic locking connecting elements of the above type for achieving a locking magnetic closure are described, for example, in WO 2009 / 092368 A1.

[0009] In a further development of the invention, the locking piece of the second magnetic locking connection element, which has a detent projection, engages with the first magnetic locking connection element in a closed position with a detent projection of the spring locking element of the first magnetic locking connection element, with which it is connected.

[0010] In an embodiment of the invention, a web profile is arranged between the two side profiles and / or between a side profile and a base profile, which is connected to the two side profiles and / or to a side profile and the base profile via interlocking first and second magnetic locking connection elements.

[0011] In a further embodiment of the invention, a groove is arranged on at least one cover side of a base profile, on the base of the groove or on one of its side flanks at least one first and / or one second magnetic locking connection element is arranged. This makes it possible to achieve a groove connection that is easy to fix.

[0012] In a further development of the invention, the groove is formed by two guide rails arranged parallel to each other, which form an insertion, wherein at least one guide rail has at least one first magnetic locking element and / or a second magnetic locking element on its side opposite the other guide rail. Preferably, an insertion part is provided which has at least one first magnetic locking element and / or a second magnetic locking element, and which, when inserted between the two guide rails, can be locked in place with one of the at least one second magnetic locking element and / or first magnetic locking element.

[0013] In an embodiment of the invention, at least one side part and / or a base profile is formed from two side part sections, wherein one of the two side part sections is provided with a first magnetic locking connection element and the other side part section with a second magnetic locking connection element, the two side part sections being detachably connected via the first and second magnetic locking connection elements. This enables a simple connection of two side part sections to one another.

[0014] The invention further relates to a frame arrangement comprising at least two frame constructions of the aforementioned type, wherein the at least two frame constructions are detachably connected to one another via first and second magnetic snap-fit ​​connection elements. This enables a simple connection of several frame constructions to one another.

[0015] The invention further relates to a frame arrangement comprising at least one frame construction of the aforementioned type and at least one attachment, wherein at least one frame construction and at least one attachment are detachably connected to one another via first and second magnetic snap-fit ​​connection elements. The component can, for example, be a wardrobe item, a lamp, or a fastening hook.

[0017] The frame construction chosen as an exemplary embodiment according to Fig. 1 is formed from a base profile 1, at each of whose two ends a side profile 2 is arranged orthogonally to the base profile 1. At their ends opposite the first base profile 1, the two side profiles 2 are connected to each other by a cover profile 3 arranged between them.

[0018] The first base profile 1 is designed as an aluminum profile and, in the exemplary embodiment, has a rectangular base. The first base profile 1 is provided with a first groove 11 along each of its opposite longitudinal side faces. On its side facing the opposite cover profile 3, the base profile has further second grooves 13 arranged parallel to each other. The second grooves 13, like the first grooves 11, have a C-shaped cross-section.

[0019] The base profile 1 is connected to the side profiles 2 via a miter joint and a magnetic snap connection 4. The cover profile 3 has a fifth groove 31 along each of its opposite longitudinal side faces and further parallel sixth grooves 33 on its side facing the opposite base profile 1. The cover profile 3 is also connected to the side profiles 2 via a miter joint and a magnetic snap connection 4.

[0020] For this purpose, first magnetic locking connecting elements 41 are arranged on one of the beveled connecting surfaces 12 of the first base profile 1, and second magnetic locking connecting elements 42 are arranged on the other, opposite connecting surface 12. Similarly, first magnetic locking connecting elements 41 are arranged on one of the beveled connecting surfaces 32 of the cover profile 3, and second magnetic locking connecting elements 42 are arranged on the other, opposite connecting surface 12.

[0021] The side profiles 2 are each provided with a third groove 21 along their opposite longitudinal side surfaces and each has first magnetic locking connecting elements 41 on one of their chamfered connecting surfaces 22 and second magnetic locking connecting elements 42 on the other, opposite connecting surface 22. On their sides facing the other side profile 2, the side profiles 2 are also provided with further fourth grooves 23, each having the same C-shaped cross-section as the first and sixth grooves 13, 33 of the base profile 1 and the cover profile 3, with which they are aligned.

[0022] The side profiles 2 are connected via their first and second magnetic locking connecting elements 41, 42 to the second and first connecting elements 42, 41 of the base profile 1 and the cover profile 3. In each case, the locking piece 421 of a second magnetic locking connecting element 42 engages with its locking projection 422 into the first magnetic locking connecting element 41, which has a spring-loaded locking element, thus locking into place. The first magnetic locking connecting element 41 is shown schematically in Fig. 14 a) and the second magnetic locking element 42 is shown schematically in Fig. 14 b) shown.

[0023] In the exemplary embodiment, the base profile 1 is further provided along its outwardly facing central longitudinal axis with two spaced-apart second magnetic locking connecting elements 42, which are inserted into locking receptacles 14 of the base profile 1 via locking inserts 423. These second magnetic locking connecting elements 42 serve for attachment to a further frame structure provided with first magnetic locking connecting elements 41.

[0024] In the exemplary embodiment according to Fig. 6. The frame construction largely corresponds to the frame profile according to Fig. The assembly is formed by a base profile 1, which is mitered to two side profiles 2. Instead of a cover profile, a web profile 5 is arranged centrally between the side profiles. In this embodiment, the base profile 1 and the web profile 5 are connected to the side profiles 2 by corner connectors 6. The corner connectors 6 are inserted into one of the first and fourth grooves 13, 23 of the base profile 1 and the side profiles 2, as well as into a seventh groove 51 provided in the web profile 5, and are fixed in place by means of screws. The seventh groove 51 also has a C-shaped cross-section.

[0025] The basic profile 1 is also provided on its outwardly directed surface along its central longitudinal axis with two spaced-apart second magnetic locking connecting elements 42, by means of which it can be attached, for example, to a frame construction according to the first embodiment.

[0026] Furthermore, the web profile 5 is provided on its side surfaces with a first magnetic locking connection element 41 for fastening objects having corresponding second magnetic locking connection elements.

[0027] In the exemplary embodiment according to Fig. 11. The frame construction largely corresponds to the frame profile according to Fig. 6. Instead of the second magnetic locking connecting elements used there, first magnetic locking connecting elements 41 are inserted here into corresponding locking receptacles 14 of the base profile 1. The frame construction thus formed is therefore compatible with the frame construction according to Fig. 6. The base profiles can be fastened together by placing them against each other, wherein the locking pieces 421 of the second magnetic locking connection elements 42 automatically engage with the spring locking elements 411 of the first magnetic locking connection elements 41 and establish a positive connection with them. Fig. Figure 14 shows a possible embodiment of the magnetic locking elements 41, 42 for a magnetic locking connection 4. The first magnetic locking element 41 according to Fig. 14 a) comprises a mounting plate 412 in which a spring locking element 411 is inserted. A sliding groove 413 is provided in the mounting plate 412, via which the locking piece 421 of a second magnetic locking connection element 42 is magnetically drawn into the spring locking element 411. The second magnetic locking connection element 42 is arranged according to Fig. 14 b) formed by a locking piece 421 having a locking projection 422, which is connected in the manner of a screw head to a threaded pin 424, over which the second magnetic locking connecting element 42 can be screwed into a component QUOTES INCLUDED IN THE DESCRIPTION
