Abstract

The aim of the invention is to provide a system for a kit used to build retail shelving or similar, with which the number of suspension parts, brackets, cross members or similar to be held can be drastically reduced for use with different support systems. This is achieved by two sheet metal parts (42, 45, 52, 55, 62, 65) designed as punched parts or similar and having a central slot (43, 46, 53, 56, 63, 66) in at least one sheet metal part (42, 45, 52, 55, 62, 65) that runs from one end face, said slot permitting an interlocking engagement of the two sheet metal parts (42, 45, 52, 55, 62, 65) to form an engagement cross fitting in the hollow body (2) to be fixed, at least one edge surface (44, 47, 54, 57, 64, 67) of each sheet metal part (42, 45, 52, 55, 62, 65) tapering in the insertion direction.

Description

'Bausatzuniversalverbindunσ "

The invention relates to a kit for connecting a trained at least partially as a hollow body cross member or support arm with a provided with engaging slots horizontal or vertical support, in particular for the formation of shelves or the like.

Shopfitting systems, store shelves and similar arrangements, for example for the presentation and sale of goods, often use different components. These may e.g. be attached to a fixed support structure to accommodate the goods to be presented. As an example, carrying devices for shelves are called, but also support arms to which hangers can be hung, in a straight or kinked variant, and a variety of other support systems, depending on the type of goods. It is also possible to attach further elements to the corresponding support systems, for example sales promotion instruments, billboards and much more.

It is customary for a particular support structure to match the corresponding cross members or brackets or other parts to be attached specifically to the support structure used. Since the connection to the support system is usually designed to be detachable in order to facilitate conversions, the most varied connection systems are used. These may be suspension systems, spring / groove designs, and virtually the entire known range of detachable connections.

Thus, for each carrier system, a precisely matched system of carrying parts or suspension parts is produced, under still in different sizes, material properties, surface coatings, etc.

Thus, for a plurality of support systems, the number of supporting and suspension parts to be kept multiplied, since these, as stated, must be tailored to the support system used to ensure the reliable and secure connection with each other.

The object of the invention is to provide a system with which the number of hooking parts to be present, supporting arms, cross members and the like. can be drastically reduced for use with different support systems and still provide a full range of corresponding elements for each of the support systems available, so that the manufacturing and storage costs can be significantly reduced together with the corresponding expense.

The invention achieves this by means of two metal sheets designed as stamped parts or the like with a centric slot from one end face in at least one metal sheet for matingly intermeshing both metal sheets to form an engagement cross in the hollow body to be fixed, at least one edge surface of each metal sheet tapering in the insertion direction History has.

As a result, a universally usable connection is created, with which each support element can be provided with a connection piece which is designed to match the carrier system used. The hollow body can assume the desired design variant at its free end, for example as a carrier for shelves, hangers for hangers and all other desired designs. The second element consists of the matching horizontal or vertical support engagement piece, which has exactly the right for secure attachment in the engagement slots of the carrier design. The engagement part is followed by one of the two metal blades with a centric slot, into which the second blade is inserted, so that a cross-shaped configuration results. In this case, the edge surface of each metal blade is designed such that it has a tapering in the insertion direction in the hollow body course.

After the mating of the two metal sheets they are inserted into the hollow body portion of the cross member or support arm and compressed. This can alternatively be done by a blow with a hammer or by machine. By compressing, in particular the sliding of the hollow body on the tapered edge surfaces, a frictional connection of the two metal sheets together and the metal sheets is achieved in the interior of the suitably designed hollow body, so that a firm connection of adjoining the hollow body cross member or support arm with the arises on the metal sheets adjoining Einhängeteil.

The resulting total part can thereafter simply be hooked into the support structure as before, the internal design of the system usually being hidden from the user.

As a result, the desired properties to achieve the object are fully achieved. In particular, the cross members or support arms or other elements adjoining the hollow body can be manufactured and stored independently of the connecting pieces fitting the support system. The same applies to the suspension systems send hangers. Only when needed, possibly only on order, then the corresponding links are connected to the corresponding support elements. Should one of the elements change, for example use a new support system or new designs of cross members or support frames are desired, they can be easily manufactured and all previously used parts remain usable and are available for all support system variants.

Further embodiments of the invention will become apparent from the dependent claims.

It is provided that a metal sheet integrally has the Einsteckschenkel for the horizontal or vertical support. As a result, the production costs can be further reduced because the entire insert then consists only of two elements that can be completely manufactured as stampings. Depending on the configuration, this can be either the vertical or the horizontally lying metal sheet.

It is advantageous that at least one of the metal sheets has outward-pointing latching projections for application in notches of the respective support arm. As a result, on the one hand a torsional security of the support arm is achieved in comparison to the support structure. On the other hand, if necessary, a stop of the support arm can be achieved on the metal sheet, so that a too deep hammering is prevented.

It can be advantageous that the slit on one metal sheet covers about one third of the engagement area in the hollow body, while the slit in the other metal sheet covers about two thirds of the insertion area. Such a division of the slits in proportion to each other has proved to be particularly advantageous in terms of stability and function of the invention.

In an embodiment, it may be provided that a metal blade has an outwardly widening broadening at the end of the insertion region as an abutment shoulder for the end face of the support arm. This also makes it possible to implement or supplement an alternative or additional stop function, which offers special advantages for the functions of the overall system and the stability under certain circumstances.

Metal sheets in this third embodiment.

An inventive kit is shown in Fig. 1 in more detail. A support arm 1 has at its end a hollow body 2 with notches 3.

Insertable into the hollow body are three connecting pieces for horizontal or vertical support 4, 5 and 6. They have as common component at one end two formed as stamped parts metal sheets, which are inserted into one another and can be hammered into the hollow body. At its opposite end, they have a suitable fitting to the horizontal or vertical carrier male member.

In the variant of the kit according to the invention shown in more detail in FIGS. 2 a to 2 d, the insertion part 40 lying horizontally in the position of use is used, which has a latching nose 41 for fixing in the carrier in the inserted state. This is followed in one piece by a metal blade 42, which has a central slot 43 at its free end. The lateral edge surfaces 44 taper slightly towards the free end of the metal blade.

The corresponding second metal blade 45 also has a central slot 46, the depth of which is approximately twice as deep as the corresponding slot 43 of the first metal sheet. The lying in the insertion direction edge surfaces 47 also taper slightly in the insertion direction. In addition, on both sides of the insertion direction facing away from the end 2 locking projections 48 are provided for engagement in the corresponding grooves 3 on the support arm 1.

To assemble the system, the two metal sheets 42 and 45 are first inserted into the slot 43 and 46, respectively, so that the combination part 4 shown in FIG. 2b is formed. This is then inserted in a further step in the hollow body 2 and either machined or, for example, by a blow with a rubber hammer into the stop position in the hollow body taken, as shown in Fig. 2c. The locking lugs 48 have been centered by the slightly tapered shape of the engagement grooves 3 in this, so that a defined and twist-proof alignment of the hollow body 1 with respect to the connection part 4 is formed.

Due to the tapered shape of the edge surfaces 44 and 45, on the one hand, the impacting is made possible and, on the other hand, the fixation of the two elements is achieved with one another. At the same time thereby the two metal sheets 42 and 45 are fixed together by the externally applied pressing force, so that a stable overall composite of the systems is formed.

A further embodiment of the invention is shown in FIGS. 3a to 3d. The support arm 1 is similar to the un formed the previous embodiment. However, here the insertion part 50 is designed for the support structure for engagement in a specially designed vertical support and has a correspondingly fitting form-fitting design. tion with latch 51 for fixing the element in the position of use. This is again followed in one piece by the first metal sheet 52, which is formed by nesting the slits 53 in the matching slot 56 of a second metal sheet 55. Both metal sheets 52, 55 in turn have tapered edge surfaces 54 and 57, respectively. Locking projections 59 serve to prevent rotation of the hollow body 2. In addition, latching lugs 58 are provided in this embodiment, which form a stop for the hollow body 2.

The assembly otherwise proceeds analogously to the embodiment described above.

In the embodiment shown in FIGS. 4a to 4d, two interlocking metal blades 62 and 65 are again provided for receiving in the hollow body 2 of a support arm, which in turn have mating slots 63 and 66 and whose edge surfaces 64 and 67 taper in the insertion direction. Again, abutment shoulders 68 and locking projections 69 are provided.

For hanging in a vertical support corresponding hanger lugs 61 and more suitable for vertical support elements are provided in the side facing away from the support arm 1 side. To stabilize the overall arrangement, a lower support tongue 70 is additionally provided, which additionally stabilizes the connection of the plug-in part 60 to the support arm 1.

Of course, the foregoing invention is not limited to the above embodiments, but may be modified in many ways without departing from the spirit. In particular, the designs of the support arms as well as the connection elements provided for fixing in the horizontal or vertical or other support systems are freely modifiable as long as the universal connection remains within the scope of the claims. The same applies to the related materials, dimensions and the like.
