Description

The invention relates to a plastic display pallet for storing objects to be transported and. to present. Such a pallet comprises a floor having a lower face and an upper face placed at a distance from the latter. The upper face and the lower face are connected by an edge consisting of four lateral faces; two of these four lateral faces are opposite to one another and run parallel to each other. The neighboring side faces then touch in corner areas. The display pallet further comprises support elements, for example feet or pads, which are designed to protrude from the underside of the floor, and at least one housing for presentation, intended for the fixing a display.

The display pallets are used on the one hand for the transport of objects, that is to say goods. A wide range of applications, as well as possible integration into a deposit system, require as homogeneous a structure as possible for pallets of this type, as regards the dimensions of the floor on which the goods are stored. In the state of the art, for example, europallets having a floor base area of 800 x 1200 mm are known up to display pallets having a base area of 400 x 600 mm. For installation in sales areas, it is advantageous to use pallets with a base area as small as possible, and in addition it is possible to manufacture plastic display pallets in many different colors, which can be adapted display cases, which generally seem more attractive than, for example, wooden europallets.

With regard to the so-called pallet-displays, these are pallets that are also mounted in sales areas, to present directly to the customer goods that are arranged on them, without them beforehand be stored by staff on shelves, for example to put these goods particularly forward. The display pallets serve both for the transport and presentation of goods. The pallets are then surrounded by what are called "displays", which must act on the customer in a more attractive way than the simple presentation on a pallet. With regard to these "displays", these are generally assemblies of cardboard or printed cardboard, which are fixed in the corresponding housing for fixing the "displays", which can be reported or configured on the floor or on the side faces. In addition, the "displays" can be used during transport also to fix the goods housed on the pallet.

Such a plastic display pallet is described for example in DE 10 2011 003 999 A1, the pallet exposed to it has the dimension of a quarter of europallet, that is to say a base area of 400 x 600 mm.

In order to achieve as much flexibility as possible, mainly during the presentation, but preferably also during the transport of the goods, it is occasionally necessary to position several smaller pallets next to each other, for example to present more goods. large dimensions. In this case, it must be ensured that two pallets arranged next to one another can be assembled together to prevent a shift of one of the two pallets with respect to the other. . To this end, the document US 5,310,063 describes a pallet system in which, on the upper face of the floor on which the goods are stored, openings or recesses in the form of a slit are made on the edges, and the result is an assembly in that a U-shaped connecting element is, by each of its branches, plugged into a respective opening of a pallet. The pallets are then protected against lateral offsets in the plane of the floor. The assembly must then be carried out before the goods are stored on the pallet or on the set of pallets.

Also described in DE 10 2012 004 539 A1 is the description of different possibilities for assembling several pallets. One of the systems that is exposed to it uses clamping brackets, which are inserted in corresponding insertion housings arranged on the upper face of the pallets; to achieve the assembly, it is necessary, here too, access from above to the surface of the floor. Other assembly mechanisms use magnetic elements and are attached to the underside of the pallets. Mechanisms of this type are, because of their complexity, more likely to fail than purely mechanical assemblies, and may furthermore, in case of improper handling, be damaged, for example with a forklift truck.

The known possibilities in the state of the art for assembling two pallets have in common the fact that such an assembly can only be performed when the pallets are not loaded, because it is necessary to be able to access the surface of the floor from above. or the assembly is complex with elements and electromagnetic circuits, which goes against frequent use, for example in a deposit system.

The present invention therefore aims to improve a display pallet of the type described above, by providing means as simple as possible to assemble two or more pallets, which make it possible to achieve an assembly of pallets, even when they are already loaded, to increase the flexibility of the use of display pallets of this type.

This object is achieved with a display pallet of the type described above, in that the pallet comprises at least one connecting element, essentially designed in the form of a plate, comprising two large parallel outer faces, for the assembly with a additional display pallet with the same structure. At least one corner area of at least one side surface is provided with a housing, which is designed as a slider for partial insertion of the assembly element (s) along an insertion direction. The insertion direction is then parallel to a longitudinal direction of the side face against which the housing is formed. The connecting element is preferably plastic, but may also be of other materials, which have the required hardness and flexural rigidity, which almost perfectly prevent an offset from each other by two. Assembled pallets, without breakage of the connecting element. For example, it is also possible to use wooden or steel fasteners. Plastic however has the advantage of more economical manufacturing in large numbers.

The housing is arranged so that the substantially plate-shaped connecting member can be inserted into the housing from the outside, from the side, the insertion direction being parallel to the longitudinal direction of the side face. that is, the insertion takes place parallel to the plane of the lateral face. The longitudinal direction of the lateral face is then the direction parallel to the edge between the lateral face and the upper or lower face of the floor, the transverse direction being that which connects the upper face and the lower face, and being perpendicular to the direction longitudinal.

Preferably, in the inserted state, the large faces of the connecting element are then parallel to the lateral face, this embodiment being particularly simple to handle and allowing a particularly stable connection with respect to a offset perpendicular to the direction of insertion. The assembly between the inserted connecting element and the floor is, in the directions perpendicular to the direction of insertion, that is to say in the direction of the normal to the plane of the floor and the normal to the plane of the considered side face, preferably a shape matching assembly, to facilitate reversible removal and placement of the joining member. Along the direction of insertion, it is possible to separate without difficulty, by pulling on it, two pallets which are assembled in the manner described by an assembly element. To prevent this, and to achieve a more stable assembly, which prevents inadvertent separation or misalignment of two pallets with respect to each other, the assembly between the inserted assembly member and the floor has therefore place, along the direction of insertion, preferably by a dynamic link. This can be achieved for example by the fact that the plate-shaped element has a thickness - between the two large outer faces - which corresponds to an oversizing compared to an opening of the housing in which the plate-shaped element must to be inserted. In this way, a tightening effect is created, the strong friction by adhesion prevents the assembly element from inadvertently discarding, or inadvertently two pallets are separated from each other. The connecting element is made essentially in the form of a plate, the plate form relating to the ratios between the dimensions of the surfaces which delimit the element, a plate generally has two large surfaces or two large faces and - under the parallelepipedic shape, here preferred - four narrow faces. If the plate-shaped fastener has an oval or circular shape, then there is only a narrow face.

The housing can be arranged in different ways. In a preferred embodiment, less susceptible to wear, the housing comprises an inner wall, recessed inwardly relative to the surface of the side face. In one embodiment of the housing, for example in the form of a pocket, the slide - the object of which is to prevent the connecting element from slipping or falling towards the outside of the pallet - is made in the form of a wall outer housing. In the case of a pocket-shaped housing, the fact that the latter can only with difficulty be rid of soils which can easily penetrate in such a pocket, in particular because of the proximity with the ground, and to be deposited there represents a disadvantage. This can have the consequence that the assembly element can no longer be inserted into the housing without difficulty, or as far as necessary, so that two assembled pallets can not be properly wedged against each other. In an advantageous embodiment, the outer wall is thus not designed in a continuous manner from top to bottom along the transverse direction of the lateral face, the slide of which has on the contrary an elevation or a bulge in the form of rib, protruding upwardly from a lower edge of the side face, and a raised or bulge-shaped rib projecting downward from an upper edge of the side face - most often identical to the edge between the lateral face and the upper face of the floor. It is then sufficient for the rib-like elevation to take off only slightly, for example from a distance in the range of a few millimeters to about 2 cm, depending on the size of the pallet, the upper edge or the lower edge. In general, for example a height of about 1 cm should provide sufficient strength on the one hand for the stability of the slide, and on the other hand also against shear forces, which in case of shifting by inadvertence of the two pallets, can be generated perpendicular to the direction of insertion. The plate-shaped fastener should not be designed as a solid plastic plate, but may also have a grid-like internal structure, for example to save material. Even the floor is most often designed with a grid structure. The assembly element can be configured in different ways, depending on how two pallets are to be assembled to each other, and how the housings are arranged against the side faces. Thus, two rectangular pallets can be coupled to each other either by their shorter faces or by their larger faces. From a pallet of dimensions 400 x 300 mm, in the case of a coupling by the shorter faces, it is possible to manufacture for example a pallet 800 x 300 mm, in the case of a coupling along the faces larger a pallet of dimensions 400 x 600 mm, which corresponds to a quarter of the size of a europallet. The eighths pallet, dimensions 400 x 300 mm, have the advantage that it is possible, in the same space that requires a quarter pallet, to present, each particularly forward, several different goods. It is then possible to provide on each of the four lateral faces of the corresponding housing for the assembly element, that is to say generally eight housings, so that it is necessary to use only one type of connector. However, in order not to have a negative effect on the stability of the pallet, it is alternatively sufficient to design the housing only on two opposite lateral faces of the pallet, and to make available for this purpose different types of connectors.

In a first embodiment, the assembly element is therefore designed as a connector of a first type, for assembly to an additional display pallet against the lateral face against which the housing is made, parallel to the direction of the housing. 'insertion. Here, there are thus two pallets assembled to one another by the side faces which are parallel to the direction of insertion.

In a preferred embodiment of this configuration, the connector of a first type is formed of two substantially plate-shaped partial elements, each of the large outer faces being formed against each of the one of the partial elements, and the elements parts being assembled together at one of their narrow faces. In addition, each of the partial elements may, at least in an upper and / or lower lateral zone with respect to the direction of insertion, each of which is made against the narrow faces which delimit the rear narrow faces at which the partial elements are assembled to each other, be designed to have a thickness that is oversized relative to the distance between the inner wall and the outer wall, or the rib-shaped elevation. In this way, a clamping connection can be made with dynamic connection between the connector of the first type and the pallets.

In another preferred embodiment of this configuration, each of the partial elements is, in a front lateral zone, which is made against a narrow face, which is opposite to the narrow face against which the partial elements are assembled, designed so as to shrink in at least one of the two directions perpendicular to the direction of insertion, preferably in both directions. This facilitates the insertion of the assembly element into the housing.

In another preferred embodiment of this configuration, wherein the slider comprises rib-like elevations, the area between the sub-elements in each of the upper and lower side regions is designed as a groove offset on one side. In this way, one forms on the one hand a stop, which for example prevents the connector of the first type is inserted too far into the housing. On the other hand, the grooves may also be dimensioned such that the clamping connection between the connecting element and the pallet is reinforced, in that the distance between the two grooves relative to the other, that is to say in the transverse direction of the lateral face, is chosen a little larger than the distance from one another to the ribs of the rib-shaped elevations.

In a second alternative embodiment, the connecting element is designed as a connector of a second type for assembly to an additional display pallet against a side face perpendicular to that against which the housing is formed, and perpendicular to the direction of insertion.

In a preferred embodiment of this configuration, the connector of the second type has, at least in an upper side area and a lower side area with respect to the direction of insertion, which are designed against opposite narrow faces, one to the other, a thickness that is oversized relative to the distance between the inner wall and the outer wall or rib-shaped elevation. The essentially plate-like joining element can also, in its entirety, have a corresponding thickness. In this way, it is possible to make a clamping connection with dynamic connection between the connector of the second type and the pallet, this prevents an involuntary escape by sliding of the connector of the second type, and there is an increase in the stability an assembly of two display pallets.

In another preferred embodiment of this configuration, the assembly of the second type is, in a front side area and a rear side area with respect to the direction of insertion, which are designed against opposite narrow faces, one to the other, designed as narrowing perpendicularly to the direction of insertion in at least one, and preferably in both directions, however. This facilitates insertion into the housing.

In another preferred embodiment of this configuration, stops to prevent complete insertion into the housing are made on the connector of the second type, preferably on the large side, which in the inserted state is directed outwards. . With respect to the length along the direction of insertion, these stops are preferably made in the middle, so that the connector of the second type engages in each of the housings of the two pallets assembled to one another with the same depth, which is particularly advantageous when the depth of the housing is greater than the longitudinal extension of the connector of the second type.

In another preferred embodiment of this configuration, in which the slide comprises rib-shaped elevations, support elevations intended to abut against an edge of the rib, are designed on the large face which is directed outward in the inserted state. Here too, it is possible to choose the distance between the elevations on the rear face of the connecting element in the transverse direction of the lateral face so that it is a little larger than the reciprocal distance of the edges of the elevations. in the form of a rib, to further strengthen the clamping assembly, or simply to achieve a clamping connection, in the case where the thickness of the plate-shaped element has not been, in the lateral zones , chosen so that one can already in this way achieve a clamping assembly.

In a particularly preferred embodiment of the invention, the essentially plate-like connecting member consists of two plate-shaped partial members which are connected on one of their narrow faces by a hinge. with plastic hinge. The hinge plastic hinge is then preferably made with a predetermined distance from an edge between the narrow face and the large face, so that the two partial elements can, in the deployed state, support the against each other in outcropping by their narrow faces. The distance then corresponds to half the distance between the two plate-shaped partial elements in the embodiment of the connecting element as a connector of the first type, the joint can play the role of the stop in the case of the connector of the second type. In this way, it is possible to realize with an assembly element, both the connector of the first type and the connector of the second type. The connecting element is preferably made of one-piece plastic, the plastic hinge is designed as a solid-body joint by a very fine plastic material at this point. To prevent inadvertent tilting, locking elements can be integrated, which fix the assembly element either in the form of the first connector or in the form of the second connector.

In another particularly preferred embodiment, the connecting element is made in a modular manner, from a first substantially plate-shaped basic module and a substantially shaped second basic module. of the plate, the two basic modules being able to be assembled to one another by plug-in assemblies, in the longitudinal direction, that is to say by at least one of their narrow faces, as in the transverse direction, that is to say by at least one of their large faces. In the case of a plug-in connection, it is possible to make the connector of the first type, as the connector of the second type, by meeting by plugging second base modules. For this purpose, for example, cards are made on one of the modules, and on the other corresponding sockets, that is to say that one can consider a mixed implementation of plugs and sockets. This system can be supplemented by detents, which prevent two modules from inadvertently separating from each other. The plug-in connection can also be provided with a slide.

In a particularly preferred embodiment of this variant, for assembling the first base module to the second base module in a longitudinal direction, a first dovetail slide is made against a narrow face of the first base module, and a first rail, adapted to the first dovetail slide, is made against the narrow face of the second base module. In addition, or alternatively, to assemble the first base module to the second base module in a transverse direction, a second dovetail slide is made against a large face of the first base module, and a second rail adapted to the second dovetail slide is made against a large face of the second basic module. Compared to a plug-in connection itself, this has the advantage that the base modules can not be separated so easily from one another, so that the assembly is more stable. As each of the two basic modules comes into engagement with another pallet, there is in this way strengthening of the assembly between the pallets. This embodiment also equivalently includes a first base module, against which one of the rails, or both rails, or a second base module is formed, against which is made / are made one of dovetailed slides, or both.

In a particular embodiment of this variant, a connector of the third type, for assembling four display pallets, is made from two first basic modules and two second basic modules, two different basic modules being assembled each time. to each other in the longitudinal direction and in the transverse direction. This gives a high flexibility for the assembly possibilities of different pallets. Depending on the needs, it is possible to manufacture sets of several pallets. The size of the pallets is then basically arbitrary, and preferably their size is 400 × 300 mm, and, compared to the pallets display known in the state of the art, having dimensions corresponding to a quarter of a europallet, it this is "mini-pallet display".

In another preferred embodiment, a pocket-shaped storage housing for receiving (the assembly member or, when it is made up of several individual parts, at least one of its individual parts, one of the side faces of the display pallet For example, a storage compartment for two basic modules can be made in each pallet, the assembly elements can be stored there when they are not used, so that we can guarantee that the assembly element, and the pallet will always define a composite structure.It can also in this way prevent the loss of the assembly element, which is considerably smaller than the pallet when the pallets are separated from each other Finally, this also allows flexible use on site at the customer.

It will be understood that the features mentioned above, and those which will be further explained below, may be used not only according to the combinations indicated, but also according to other combinations, or in an autonomous manner, without however depart from the scope of the present invention. The invention is explained in more detail hereinafter by way of example with the aid of the accompanying drawings, which also disclose important features for the invention. On the drawings:

Figure 1 shows a plastic display pallet for storing objects to be transported and presented. This display pallet comprises a floor having a lower face - here not shown -, an upper face 1 at a distance from the latter, and an edge, which connects the upper face 1 and the lower face, consisting of four lateral faces 2.1, 2.2, 2.3 and 2.4 which two by two are opposed and extend parallel to one another, and the neighboring side faces touching at the corner areas 3. The display pallet presented here has a rectangular shape, the Short side faces are called 2.1 and 2.3, the long side faces 2.2 and 2.4. The side faces may, for example when viewed from above, have a length of 300 mm and 400 mm, 400 mm and 600 mm, or any other dimensions. Of course we can also consider a square realization of the floor.

The display pallet also has support elements in the form of feet 4, which are configured to protrude from the underside of the floor. The feet 4 are here at least partially hollow inside, so that several display pallets of the same type can be nested when they are arranged stacked on each other in the empty state. Instead of the legs 4, the support elements may, when necessary, be made in the form of pads, or include, in the case of larger pallets, just as well combinations of feet and pads . A display pallet also has at least one housing for receiving a "display", ie for example a printed carton, which surrounds the goods arranged on the pallet. The present display pallet is suitable for housing several types of "displays", which are assembled to the pallet using different housing, it has several different types of housing 5.1-5.6, the slot-shaped housing 5.3 and the housing 5.6 in the form of a dovetail slide, which can also be combined to give a single housing.

The display pallet further comprises at least one assembly element essentially having a plate-like structure of a plastic material, comprising two large parallel outer faces for assembly to another display pallet of the same construction. Joining elements of this type are shown for example in Figure 3, Figure 5, Figure 7 and Figure 8, and are described in more detail below.

In the display pallet, in at least one corner region 3 of at least one side face 2.1, 2.2, 2.3 or 2.4, a housing 6 is formed, which is designed as a slide for partial insertion of at least one element. assembly along an insertion direction. In this case, two housings 6 are made on each of the two shorter longitudinal faces 2.1 and 2.3. Indeed, it is just as possible, with such good results, to make the housing 6 on the longer narrow faces 2.2 and 2.4, or to achieve corresponding housing 6 on the four side faces.

Figures 2a and 2b show side views of the display pallet shown in Figure 1. Figure 2a shows the narrower side face 2.1 or 2.3, Figure 2b the longer side face 2.2 or 2.4. In FIG. 2a, the direction of insertion also indicates the insertion direction by the double arrow E, it is parallel to a longitudinal direction of the lateral face 2.1, 2.3, generally parallel to the lateral face against which the housing 6 is made. In the inserted state, the large faces of the connecting element are parallel to the lateral face. Preferably, the connection between the inserted connecting member and the floor is furthermore made with shape matching in the directions perpendicular to the direction of insertion, and with a dynamic connection along the direction of insertion. In Figures 2a and 2b, the lower face 7 of the floor has also been specified. The thickness of the lateral faces 2.1-2.4, that is to say their extension transversely to the direction of insertion, corresponds here, in the corner zone 3, to the distance between the upper face 1 and the lower face 7 .

In the embodiment shown in Figures 2a and 2b, the housing 6 comprises an inner wall 8, recessed relative to the surface of the side face -the side face 2.1 respectively 2.3. The slide can then be made either as an outer wall of the housing 6, the housing 6 then has a pocket shape or, as seen here, it includes an elevation 9.1 or 9.2 in the form of a rib, which exceeds the high from the lower edge of the side face and down from the upper edge of the side face. This embodiment facilitates in particular the introduction of the connecting element and allows easier access to the housing 6, especially when it comes to cleaning the latter. On the side face 2.2 and in a corresponding manner on the side face 2.4, there is also provided a pocket-shaped storage housing 10 for accommodating the connecting element. If the joining element is made up of several individual parts, the housing can also be configured to receive one or more of the individual parts, the individual parts can also be housed in different housings. If we use a single assembly element, it is also sufficient to make a single housing.

When, in the example shown in FIGS. 2a, 2b, housings 6 are only arranged against shorter narrow faces 2.1 and 2.3, it is necessary to use a plurality of connecting elements, depending on whether to couple two display pallets one to the other by the long lateral faces 2.2 and 2.4, or by the shorter lateral faces 2.1 and 2.3. If housings 6 are on all four side faces 2.1-2.4, one type of connection element is sufficient.

FIG. 3 shows now an assembly element configured as a connector of the first type 11, the connector of the first type 11 is designed for assembly to an additional display pallet on the lateral face against which the housing 6 is made, that is, parallel to the insertion direction E. The first type connector 11, shown in FIG. 3, thus serves to assemble the display pallet shown in FIG. shorter narrow faces 2.1 or 2.3. In FIG. 4a, the pallet shown in FIG. 1 is represented, a connector of the first type 11 being here introduced into a housing 6. FIG. 4b shows two display pallets of the same type, which are assembled by a connector of the first type 11, and Figure 4c shows a display pallet in which the connector of the first type 11 is disposed in the storage housing 10.

The connector of the first type shown in FIG. 3 is formed of two essentially plate-shaped partial members 12.1, 12.2. A plate, or such a plate-shaped element, generally has two large faces and four narrow faces, here one respectively has one of the large faces of the connecting element which is made on respectively one of the partial elements. 12.1, 12.2. The large face 13.1 of the partial element 12.1 thus corresponds to one of the large faces of the assembly element, and correspondingly the partial element 12.2 has a large face, which is not shown here . The two partial elements 12.1 and 12.2 are joined to one another by one of their narrow faces. Each of the two partial elements 12.1 and 12.2 furthermore has, at least in an upper lateral zone with respect to the direction of insertion, and in a lower lateral zone which is configured against the narrow faces which are adjacent to the narrow face against which the partial elements 12.1 and 12.2 are assembled to one another, a thickness which, with respect to the distance between the inner wall 8 and the outer wall or the rib-shaped elevation 9 of the housing 6 on the display pallet, presents an oversizing, so that a connection with dynamic connection, particularly good, is created by a clamping effect, when the assembly element is inserted in the housing 6. In Figure 3, the upper lateral zone and the lower side area are not particularly specified, and here the total partial element 12.1 or 12.2 has a corresponding thickness, which from a point of view of The manufacturing technique is easier to achieve because of the use of flat surfaces.

Each of the partial elements 12.1 and 12.2 is further configured by tapering in at least one of two directions perpendicular to the insertion direction, here in both directions, in a front lateral zone 14, which is configured against a face narrow, which is opposed to the narrow face against which the partial elements 12.1, 12.2 are assembled to one another. The insertion is thus facilitated. On the face of the connector of the first type at which are assembled the two partial elements 12.1 and 12.2, there are also bulges 15, which run along the edge of the narrow face against which are assembled the two partial elements. 12.1 and 12.2. These bulges 15 allow better handling when the connector of the first type must again be removed from the housing 6, or also the storage housing 10, so that it is possible for example to grasp with a corresponding tool or with the fingers, to remove the assembly element from the housing 6. Basically, it is sufficient that the two partial elements 12.1 and 12.2 are each assembled against a respective narrow face, which then form the common rear face 16 of the collector of the first type 11, the connector the first type 11 then has the shape of a U. If the housing 6 is however not configured in the form of a pocket, but the slide has rib-shaped elevations, the zone between the partial elements 12.1 and 12.2, in the upper lateral zone and in the lower lateral zone, is each time configured as a groove 17, recessed on one side. Their dimensions can then be defined in such a way that, when they are inserted, a clamping effect is also created between the ridge-shaped elevation ridges 9.1 and 92.2, as well as the central surfaces of the groove 17 between the two elements. partial 12.1 and 12.2.

FIGS. 5a and 5b show an assembly element configured as a connector of the second type 18, which element is configured for assembly to an additional display pallet against a lateral face perpendicular to that against which the housing 6 is made, and perpendicular to the insertion direction. In the example shown in Figure 1, it is thus an assembly along one of the longer narrow faces of the display pallet. A second type connector 18, inserted in the housing 6, is shown in Figure 6a. Figure 6b shows two pallets assembled by a connector of the second type.

Here again, the connector of the second type 18 has at least in an upper lateral zone and a lower lateral zone with respect to the direction of insertion, zones which are configured against narrow faces opposed to one another, a thickness which has an oversized relative to the distance between the inner wall 8 of the housing 6 and its outer wall or its raised 9.1, 9.2 rib-shaped. The thickness of the second connector, that is to say the distance between the two large faces, can also be chosen so as to continuously have a corresponding oversize, which from the point of view of the manufacturing technique is easier to handle, because it is then necessary to manufacture only flat surfaces. In Figure 5a, the connector of the second type 18 is presented in an oblique view from above. Figure 5b shows a view of the upper narrow face and the lower narrow face.

The connector of the second type 18 is, moreover, in a front lateral zone with respect to the direction of insertion and in a rear lateral zone, 19.1 and 19.2, which are configured against narrow faces opposed to one another, configured narrowing in both directions, perpendicular to the direction of insertion. The insertion direction E is shown in Figure 5b for clarity. The narrowing facilitates insertion, it is a help to insertion.

Basically, it is sufficient to use as a connector of the second type 18 a plate-shaped element, which has a large inner surface 20.1 and a large outer surface 20.2, particularly when the housing 6 is configured as a pocket. Preferably, stops 21, intended to prevent complete insertion into the housing 6, are however configured on the connector of the second type 18, preferably on its large surface 20.2 which in the inserted state is directed outwards. With respect to the length along the direction of insertion, they are preferably arranged centrally.

In a display pallet in which the slide comprises rib-shaped elevations 9, as seen in FIG. 1, preferably support elevations 22, to provide support against an edge of the rib-shaped elevation 9 , are made on the large outer surface 20.2, that is to say on the large surface which, in the inserted state, is directed outwards. The position of these support elevations 22 can then be chosen so as to further improve the clamping effect, that is to say the connection with dynamic connection along the direction of insertion. The distance eiitre the outwardly directed surfaces of the support elevations 22 is in this case a little larger than the reciprocal distance between the edges of the rib-shaped elevations 9 of a housing 6.

To prevent that, according to the face at which two display pallets must be joined, it is necessary to use different assembly elements, there are different possibilities. For example, pallets may be used in which housing 6 is provided on both the longer narrow faces 2.2 and 2.4 than on the shorter narrow faces 2.1 and 2.3. An example of such a palette is shown in Figure 7.

Or again, one can also build assembly elements that can be converted from a connector of the first type to a connector of the second type, the conversion can be performed on the element itself, without additional auxiliary elements. A first assembly member of this type, configured as a combined connector 23, is shown in Figures 8a-c. The combined connector 23 consists of two plate-shaped partial elements 24 which are connected on one of their narrow faces by a plastic hinge hinge 25. With this combined connector 23, a connector of the first type, such as shown in Figure 8a, can without difficulty, that is to say without additional auxiliary means, be converted into a connector of the second type, as shown in Figure 8c. Figure 8b shows the transition. In this way, it is possible to produce the same assembly element for assembling two display pallets, both on the narrow face that is longer than on the shorter narrow face, even though housings 6 are only configured against one of them. both types of narrow faces. The plastic hinge hinge 25 is disposed each time at a distance from the edge of the narrow faces, so that when converting to the connector of the second type, the stop 21 can be realized, and in the case of the connector of the first type, the distance between the two partial elements 24 corresponds to the distance necessary for insertion into two housings 6 of two pallets arranged one against the other. Of course, the hinge plastic hinge can also be configured against another of the four narrow faces, in which case however a conversion of a connector of the first type into a connector of the second type is not possible.

Another possibility for producing an assembly element that can be used both as a connector of the first type and as a connector of the second type consists in composing the assembly element in a modular manner from a first basic module 2 6.1 and a second basic module 2 6.2, the latter two being essentially configured in the form of a plate. Such basic modules are shown in Figures 9a-c. An assembly of the first type and an assembly of the second type can be manufactured by plug-in assemblies from these two base modules 26.1 and 26.2, a plug is for example made against one of the basic modules 26.1, a socket against the base module 26.2, these being made against at least one of the respective narrow faces, to manufacture an assembly of the second type, and / or against one of the large surfaces, to be able to manufacture an assembly of the first type.

In a particularly preferred embodiment, as shown in FIGS. 9a and 9b, a first dovetail slide 27.1 is made against a narrow face of the first base module 26.1, and a first rail 27.2, adapted to the first dovetail slide 27.1, is made against a narrow face of the second base module 2 6.2, for the purpose of assembling the first base module 26.1 with the second base module 2 in a longitudinal direction. In this way, it is possible to already manufacture a connector of the second type from two basic modules 26.1 and 26.2. Alternatively, or preferably in addition, to assemble the first base module 26.1 to the second base module 26.2 in a transverse direction, to form the assembly of the first type, it is realized on a large face of the first base module 2 6.1 a second slide 28.1 dovetail and against a large face of the second base module 26.2 a second rail 28.2, adapted to the second slide dovetail. In the representation of FIGS. 9a, 9b, the second dovetail slide 28.1 is made in an equivalent manner against the second base module 26.2, and correspondingly the second rail 28.2 against the first base module 26.1. . In this way, it is possible to manufacture the connector of the first type when the two basic modules are united in the second dovetail slide 28.1.

With four basic modules of this type, each time two basic modules 26.1 and 26.2, it is also possible to implement a connector of the third type 29, shown in FIG. 9c. Two different basic modules are here each time assembled to each other in the longitudinal direction and in the transverse direction. With such a connector of the third type, four display pallets can be assembled simultaneously. Or again, it is also possible to make means on the rear faces 16 of two connectors of the first type 11, as shown in FIG. 3, which make it possible to couple two connectors of this type of the first type 11 to form a connector of the first type 11. third type 29. The basic modules would be, in this case, two connectors of the first type 11, which on their rear faces 16 are distinguished by the configuration of the elements for the plug-in connection - for example a dovetail slide .

The display pallet described above, with the corresponding connecting element, allows for flexible mounting of several display pallets on site to obtain larger units, even when these pallets must already be loaded. By storing or preserving the assembly elements in a housing provided for this purpose on the pallet, it is possible to simultaneously reduce the risk of assembly elements being lost when they are not used because the pallet and the assembly element need not be kept at different points.
