[0049] FIG. 11 shows a perspective view of a further design example of a sales table according to the invention.

[0050] FIG. 1 shows a perspective view of a design example of a socket pipe connection according to the invention 10.

[0051] The socket pipe connection 10 comprises at least one first pipe 12 and at least one second pipe 14.

[0052] In addition, the socket pipe connection 10 comprises at least one elastic blocking element 16.

[0053] The first pipe 12 and the second pipe 14 are each square pipes of galvanized steel. In principle, the square pipes can be made of steel, stainless steel, aluminum or similar.

[0054] The inner diameter of the first pipe 12 is larger than the outer diameter of the second pipe 14.

[0055] The inner diameter of the first pipe 12 and the outer diameter of the second pipe 14 are selected here to form a fit (see also FIG. 2).

[0056] As can be seen in FIGS. 1 and 2, the second pipe 14 is inserted into the first pipe 12 through a recess 18.

[0057] The recess 18 is arranged in an outer surface 20 of the first pipe 12, namely the outer surface 20 facing the second pipe 14, and extends there over the entire width of the outer surface 20.

[0058] The height of the recess 18 essentially corresponds to the height of the second pipe 14 and is dimensioned in such a way that the pipe end of the second pipe 14 to be inserted into the first pipe 12 can be pushed completely into the recess 18.

[0059] The recess 18 also extends to the outer surfaces 22, 24 adjacent to the outer surface 20.

[0060] FIG. 3 shows the side view of the first pipe 12 in which the silhouette of the recess 18 is visible in the outer surface 24, i.e., an outer surface of the first pipe 12 into which the second pipe 14 is not inserted. The recess 18 is formed in the outer surface 24 in the same way as in the outer surface 22, and is essentially L-shaped. In this area, the outer surface 24 has a first area 26 which extends deeper into the outer surface 24 and which is intended for receiving the blocking element 16 (see also FIG. 1 and FIG. 2).

[0061] The second area 28 is the area in which the second pipe 14 is in the inserted or fully assembled state.

[0062] Adjacent to the first region 26 of the recess 18, a rectangular clip opening 30 is provided in the outer surface 24. A clip opening 30 of this type is also provided at a corresponding location in the outer surface 22.

[0063] The second pipe 14, as shown in FIG. 4, has a slot 32. The slot 32 is C-shaped.

[0064] The slot 32 extends over the entire width of an outer surface 33a of the second pipe 14 and over a part of each of the outer surfaces 33b adjoining this outer surface 33a, namely over half the width of the adjacent outer surfaces 33b.

[0065] FIG. 5 shows that, in the installed state, the slot 32 is pushed onto the edge of the recess 18 in the outer surface 20, specifically in the second area 28 of the recess 18.

[0066] In the assembled state, the elastic blocking element 16 is detachably inserted into the recess 18, specifically in the area 26 of the recess 18.

[0067] The elastic blocking element 16 is designed here as a plastic clip, see also FIG. 6 and FIG. 7.

[0068] The elasticity of the blocking element 16 results from the shaping of the blocking element 16.

[0069] In the design element shown, the elastic blocking element 16 is an extruded plastic profile.

[0070] In principle, however, it is also conceivable that the blocking element 16 is designed as a plastic injection-molded part.

[0071] The blocking element 16 has two substantially C-shaped spring sections 34. This shaping provides a stable and at the same time elastic structure due to the shaping.

[0072] The two spring sections 34 are each mounted on a side wall 36 of the blocking element 16. The two side walls 36 are in turn connected to the back 38 of the blocking element 16.

[0073] In the assembled state of the socket pipe connection 10, the two side walls 36 and the back 38 of the blocking element 16 fill the first region 26 of the recess 18, see in particular FIGS. 1, 2 and 5.

[0074] As shown in FIG. 6 and FIG. 7, each blocking element 16 has a shoulder abutment 40 for abutment against a part of the edge of the recess 18.

[0075] Each shoulder abutment 40 is delimited by a rounded limiting strip 42 which is also provided for abutment against a part of the edge of the recess 18. The limiting strip 42 delimits the shoulder abutment 40 in such a way that the width of the shoulder abutment 40 substantially corresponds to the thickness of the pipe sheeting of the first pipe 12.

[0076] The free ends of the spring portions 34 form rectangular clip-on sections 44 for insertion into the rectangular clip openings 30. Also, here, a rounded limiting strip 46 is provided, which delimits the clip attachment shoulder abutment 48 of the clip-on section 44.

[0077] The limiting strip 46 delimits the clip-on attachment shoulder abutment 48 in such a way that the width of the clip-on attachment shoulder abutment 48 essentially corresponds to the thickness of the pipe sheeting of the first pipe 12.

[0078] In the mounted state, the second pipe fills the second area 28 and the remaining free area 26 of the recess 18 is completely covered and filled by the blocking element 16. The area 26 is outwardly filled and covered by the side walls 36 and the back 38 of the blocking element 16.

[0079] FIG. 8 shows a perspective view of an upper frame 52 and a lower frame 54 of a design example of a sales table 50, according to the invention, which has several socket pipe connections 10 as described above.

[0080] The lower frame 54 has two main struts 56, which in turn are interconnected by transverse struts 58.

[0081] The connection of a transverse strut 58 to a main strut 56 is formed by a socket pipe connection 10 as described above. The main strut 56 forms the first pipe of the socket pipe connection 10 and the transverse strut 58 the second pipe of the socket pipe connection 10. The reverse arrangement is also possible in principle.

[0082] One or more rollers 59 (refer FIG. 10) or supporting feet may be attached to the transverse struts 58.

[0083] The upper frame 52 has four vertical struts 60 relative to the erected state.

[0084] Each vertical strut 60 is connected to a main strut 56 of the lower frame 54 by means of a socket pipe connection 10 as described above.

[0085] The vertical strut 60 is the first pipe of the socket pipe connection 10 and the main strut 56 of the lower frame 54 is the second pipe of the socket pipe connection 10.

[0086] The four vertical struts 60 of the upper frame 52 can extend beyond the socket pipe connection 10 in the erected state in the direction of the floor or the installation surface but do not touch the latter. Rather, the entire sales table 50 can only be placed on the rollers 59 or supporting feet which are fastened to the lower frame 54.

[0087] The upper frame 52 supports a sales basket 62. The sales basket 62 has several walls 64, which are formed by wire bar grates (see FIG. 10 and FIG. 11).

[0088] FIG. 9 shows a detailed view of the upper frame 52 and the lower frame 54 of a design example of a sales table 50 according to FIG. 8.

[0089] FIG. 10 shows a perspective view of a design example of a sales table 50 with rollers 59, according to the invention.

[0090] FIG. 11 shows a perspective view of a further design example of a sales table 50 according to the invention in which the sales table 50 stands on the vertical struts 60.

[0091] The assembly and the function of the socket pipe connection 10 can be described as follows:

[0092] The second pipe 14 is inserted into the first pipe 12 for the assembly of the socket pipe connection 10 and is pressed with the slot 32 onto the edge of the recess 18 in the outer surface 20, which faces the second pipe 14 in the installed state, into area 28.

[0093] The C-shape of the slot 32 allows a stable fixation of the first pipe 12 relative to the second pipe 14. In addition, this shaping allows sufficient overlapping of the portion of the edge of the recess 18 on which the second tube 14 with the slot 32 is placed.

[0094] This makes it possible to place the second pipe 14 stably and uniformly on the part of the edge of the recess 18, on which the second pipe 14 with the slot 32 is inserted, so that this connection can also be used as a load-bearing connection. As shown, for example, in FIG. 10 and FIG. 11, it is provided for the socket pipe connection 10 between the upper frame 52 and the lower frame 54, that is, the connections of the four vertical struts 60 of the upper frame 52 with the main struts 56 of the lower frame 54, that the second pipe, i.e. the main strut 56 carries the first pipe, i.e. the vertical strut 60, and the force introduction of the weight force of the first pipe and the load additionally absorbed by the first pipe is received in the region of the slot by the second pipe and introduced into the second pipe.

[0095] The total weight of the sales table 50 and the goods placed thereon is then transmitted to the socket pipe connection 10 between the vertical struts 60 and the main struts 56 of the lower frame 54 via the four vertical struts 60. The socket pipe connection 10 is arranged in each case in such a way that the blocking element 16 is located below the main strut 56 in the erected state so that the force transmission takes place only from the vertical strut 60 (first pipe) onto the main strut 56 (second pipe) in the area of the slot 32 of the main strut 56 and the blocking element 16 is not loaded. The blocking element 16 thus serves only as a securing means for the socket pipe connection 10, but is not a supporting element of this socket pipe connection 10.

[0096] If the lower frame 54 does not have rollers 59 or supporting feet, the entire weight of the sales table 50 and the goods placed thereon is carried by the four vertical struts 60 of the upper frame 52.

[0097] Due to the fit between the inner diameter of the first pipe 12 and the outer diameter of the second pipe 14, the relative movements of the second pipe 14 are restricted by the first pipe 12, and the stability of the socket pipe connection 10 is improved.

[0098] After the second pipe 14 has been inserted into the first pipe 12, it is fixed in the recess 18 by the elastic blocking element 16.

[0099] The elastic blocking element 16 also serves to dampen and prevent rattling noises.

[0100] The elastic blocking element 16 is detachably pressed into the recess 18 and detachably clipped into the clip-on openings 30 with the clip portions 44. In addition to a simple assembly, this also makes simple disassembly possible, namely by simply loosening and removing the elastic blocking element 16 from the recess 18. As a result, the second pipe 14 can then be moved again in the recess 18 so that it can be pulled out of the recess 18 and thus out of the first pipe 12.

[0101] A simple locking of the blocking element 16 is made possible by the clip-in of the clip section 44 of the blocking element 16 into the clip opening 30. Moreover, during disassembly the blocking element 16 can be simply pushed out of the clip openings 30 and thereby released.

[0102] The blocking element 16 is uniquely positioned in the recess 18, by the fact that when the locking element 16 is inserted into the recess 18 of the shoulder abutment 40, the shoulder abutment 40 strikes a part of the edge of the recess 18 and, due to the shape, can no longer be pushed or inserted further into the recess.

[0103] The advantage of the fact that the blocking element 16 substantially covers and fills the recess 18 in the assembled state is that the second pipe 14 is blocked and fixed by the blocking element 16 in the recess 18 in assembled state, i.e. when inserted into the first pipe 12. A relative movement of the first pipe 12 and the second pipe 14 relative to one another is effectively prevented. This serves not least to reduce the noise, but also for the stability of the socket pipe connection 10.
