Abstract

The tower consists of at least two successive shelves and at least one spacer support connecting these shelves, the spacer support being coupled at both ends to the respective shelf. In this case, the coupling is constructed in such a way that decoupling in the horizontal direction, i.e. transversely to the direction of the height of the tower, is possible. <IMAGE>

Description

The invention relates to a storey tower for displaying goods with a plurality of storeys and with at least one vertical spacer between two successive storeys, one end of the support being releasably coupled to the associated storey in that one of the parts: storey - an exterior support Arc or angle element with a horizontally extending line of curvature and vertically extending surface line is attached and on the other of these parts an inner arc or angle element with a horizontally extending line of curvature and vertically extending surface line is arranged, the inner arc or angle element with its outer surface on the inner surface of the outer curved or angular element is fixed in the direction of the line of curvature and in the direction of the surface line by a form-locking connection which can be engaged and disengaged.

Such a floor tower is known from DE-PS 21 53 602. In this known embodiment, an inner, rectangular angle element is attached to both ends of the spacer. The associated outer, also rectangular, angular element is located on the respective storey floor and is formed by part of an edge flange of the respective storey floor projecting upwards and downwards. Stop faces of the outer angle element are formed in that the inner contact surface of the outer angle element is set back with respect to the other inner peripheral surface of the edge flange. On the side of the inner angle element remote from the outer angle element, there is a third angle element which, together with the outer angle element, forms a shaft on the respective floor of the storey. In this shaft, the inner angular element in verti calender direction. Wedge cams are attached to the ends of the inner angle element that are spaced apart in the circumferential direction and, after the inner angle element has been completely inserted into the shaft, snap into corresponding cam receptacles on the inside of the outer angle element. To release the coupling between the inner angle element and the outer angle element, it is necessary to lift the ends of the inner angle element from the inner surface of the outer angle element to such an extent that the wedge-shaped engagement cams emerge from the recesses. Then the spacer with the inner angle element can be pushed out of the shaft in the vertical direction.

The known embodiment described so far has generally proven itself. It has now been recognized, however, that coupling together and in particular uncoupling is relatively cumbersome in this known embodiment. It is particularly troublesome when two or more spacing supports are present between two successive floors. In such an embodiment, which is also of particular interest in the context of the present invention, the difficulty in the case of the prior art described above is that when a spacer is disengaged between two successive floors and there is still one or more additional spacers between these two floors , the connections between the remaining spacers and the floors, if they allow bending at all, are subjected to bending. If such a bend is not possible, then at least one end of all the spacer supports would have to be detached from the associated storey floor at the same time, which even a skillful person can easily achieve, in particular if, for example, four spacer supports are present.

A similar problem exists in another embodiment known from DE-OS 30 06 377, in which inner arch elements are formed at the ends of trough-shaped spacing supports which interact with outer arch elements formed by a peripheral flange of the floor in the same manner as above for the case of DE-PS 21 53 603 described.

The invention has for its object to design a floor tower of the type mentioned in such a way that the coupling and uncoupling of the spacer ends with the floors is facilitated.

To achieve this object, it is proposed according to the invention that the arc or angle element associated with the spacer is exposed on its side remote from the arc or angle element of the floor level in such a way that it can be fixed or moved solely by horizontal movement relative to the arc or angle element of the floor level. is solvable. It has been shown that one can completely dispense with insertion shafts on the floor and that a stable coupling of the spacer ends can be achieved with the floors.

The inner arch or angle element is preferably attached to the spacer and the outer arch or angle element to the floor, because then the outer arch or angle element of the floor can be formed by a surrounding flange that is often necessary for reasons of stability and for security reasons.

In principle, however, it is also possible for the outer arch or angle element to be attached to the spacer and the inner arch or angle element to be attached to the floor of the storey.

According to a first embodiment, the outer and the inner curved or angular element can each have approximately a rectangular cross-section. This is an embodiment that will be chosen in particular if you want to connect square or rectangular shelves with two or four spacing supports.

According to another embodiment, the inner arc or angle element and the outer arc or angle element are each designed approximately with a partial circular cross section, in particular with a semicircular cross section. Such an embodiment is particularly appropriate if you want to connect two successive floors with two channel-shaped spacers, as known from DE-OS 30 06 377 per se.

The cross-section of the spacer supports can be adapted to the respective curved or angular element, that is to say they can also be designed to be curved or angular in cross-section. If you value optimal visibility and optimum coupling stability at the same time, it is recommended that the spacer supports have extensions pointing in the horizontal direction at the ends, which form parts of the respective curved or angular element. In this way, one achieves a large stability-enhancing support length of the arch or angle elements on the respective storey floor on the one hand and a good view of the goods on display in each case due to the relatively small cross-section of the sections of the spacing supports running between the storey floors. In the case of trough-shaped spacer supports, of which only a maximum of two are used to connect two successive storey floors anyway, the spacer supports can be designed with a cross-sectional shape that is almost identical to the entire height without restricting the view of the goods on display which corresponds to arc or angle elements.

The curved or angled elements attached to the storey floors can, under certain circumstances, be formed from a series of sub-elements which follow one another at intervals and which have an arc-shaped or angled envelope. The same applies to the arch or angle elements on the spacer supports. In view of the highest stability, it is of course desirable to design the arc or angle elements continuously.

The shelves and the spacers are preferably made of plastic, in particular injection molded or cast, transparent plastic being particularly desirable in view of good visibility.

For optimum stability, it is desirable if counter-abutment surfaces pointing away from the apex of its line of curvature are attached to the inner arch or angle element, which abut against abutment surfaces of the outer arch or angle element pointing to the apex of the respective line of curvature. In this embodiment, the spacer brackets are secured against tilting by means of the maximum distance from each other. In addition, a particularly simple production is also ensured with regard to the production by injection molding technology - and here again in particular with regard to the demolding problem.

The latching, which ensures that the counter abutment surfaces and the abutment surfaces remain in mutual contact, can thereby be ensured in the simplest way that the legs of the arc or angle element associated with the spacer support can be pivoted relative to one another about the respective apex line against elastic resistance.

Additionally or exclusively, the anti-tampering of the stop surfaces and counter stop surfaces can also be there by ensuring that the counter abutment surfaces and / or the abutment surfaces are undercut and, if necessary, provided with a bevel.

The latching of stop surfaces and counter-stop surfaces can also be additionally secured in that a slot is provided in the apex region of the arch or angle element associated with the spacer support. Thanks to such a slot, it is possible to elastically load the legs of the curved or angular elements either in tension or compression, thereby ensuring that the stop surfaces and counter-stop surfaces are properly seated in the fully assembled state, but also assembly and disassembly facilitate. At the same time, this measure reduces the requirements for manufacturing accuracy without questioning the abutment of counter-abutment surfaces and abutment surfaces in the fully assembled state. For reasons of simplification of manufacture and optimum stability, it is advantageous if the counter abutment surfaces of the inner arch or angle element associated with the spacer support are formed by end surfaces of the legs of this arch or angular element and the associated abutment surfaces of the outer arch or angle element of the floor of the storey of stop strips. In this embodiment, the pairs of forces responsible for the stability of the spacing supports on the floor of the floor lie at a maximum distance from one another and from the apex of the curved or angular elements. In order to be able to attach stop surfaces and counter-stop surfaces, if necessary, also at a smaller distance from the apex, it is possible that the counter-stop surfaces and the stop surfaces are each formed by a pairing of a cam and a recess in the mutual contact surfaces of the outer and the inner curved or angular element. You also have the freedom that either the pairing in the end region of a leg of the arch or angular element of the spacer is is arranged or that the pairing is arranged near the apex of the arc or angle element of the spacer. The vertical securing against displacement of the spacer supports relative to the floors can be ensured in that the curved or angular elements are secured in the direction of the surface line by interlocking cams and recesses on the mutual contact surfaces of the curved or angular elements. Under certain circumstances, the cams and recesses used for vertical securing can be used in a double function, on the one hand forming stop and counter-abutting surfaces and, on the other hand, serving for vertical securing against displacement. The recesses and cams are of course designed so that they do not hinder the only horizontal coupling and uncoupling of the adjacent arch or angle elements. The securing of the stop surfaces and counter-stop surfaces to one another can also be ensured by surfaces on the cams and recesses which are parallel to the line of curvature and are undercut.

The distribution of the stop surfaces, counter-stop surfaces, cams and recesses is selected with a view to the required stability of the connection between the floor and the spacers. Optimal stability is obtained if stop and counter stop surfaces are provided in the area of the ends of the arch or angle elements of the spacer supports and if interlocking cams and recesses are provided both near the apex and in the area of the ends of the arch or angle elements of the spacer supports.

Basically, the invention also encompasses any type of connection between the floor and spacing supports, in which the inner and outer curved or angular elements are secured to one another by push-button-like connections.

In order to provide a floor tower, which ensures optimum visibility and optimal access to the goods in each case, it is proposed that, in the case of a rectangular or square version of the storey floors, spacer supports are provided only in two adjacent corners. Such a floor is preferably - but not necessarily - designed as proposed in claim 1 and the following claims 2 to 21.

If spacer supports are arranged in only two adjacent corners of the storey floors, high stability of the floor tower can be achieved in particular if the spacer supports and the associated curved or angular elements are designed with different leg lengths, legs of the same length of the two spacer supports each being in alignment or are parallel to one another, and in particular again when the long legs of the spacer supports lie along the short rectangle side of the tiered floors and the short legs of the spacer supports lie along a long rectangular side of the tiered floors. In this way, a mutual connection is obtained even in the vicinity of the corners of the floors free of spacers. This applies in particular if the long legs of the spacer supports extend over at least 50% of the length of the short rectangular side of the floors.

For reasons of material savings and aesthetics, it is advisable, in the case of the spacer supports limited to two adjacent corners, which then necessarily become relatively bulky, to carry out these spacer supports with openings which, according to the principles of filigree cultivation, hardly lead to a reduction in stability. The area of the long legs of the spacer supports is particularly suitable for the arrangement of openings. These openings can be in the height direction of the Ab stand supports are elongated and can extend essentially over the entire height of the spacers between the upper and lower associated arch or angle elements. The loss of buckling stiffness which occurs through the openings can be more than compensated for by the fact that the spacer supports have stiffening ribs, in particular along their edges and / or along the edges of the openings.

An optimal distribution of the abutment surfaces and counter abutment surfaces of both the recesses and cams is obtained with an arrangement with only two spacer supports in adjacent corners of rectangular floors by the fact that the inner arch or angle elements of the spacer supports each have a counter abutment surface at the ends of the two legs of different lengths Have engagement with a stop bar on the associated outer arch or angle element of the floor and that pairings of interlocking cams and recesses on the one hand in the region of the free end of the long leg of the arch or angle element of the spacer and on the other hand in the region of the short leg of the apex Arc or angle element of the spacer are provided.

The limitation of the spacer supports to two adjacent corners of the storey floors allows the storey floors to have an upwardly and downwardly projecting edge flange along three adjacent rectangular sides and in the region of a fourth rectangle side, which is distant from the spacer supports, to have an essentially only protruding downward edge flange. In this way, the application and removal of goods is facilitated without a significant loss of stability and at the same time the view of the goods is improved. Of course, the shelves can be ribbed on the underside of the floor for additional stability. In order to avoid a risk of injury at the ends of the edge flange, it is recommended that the part of the edge flange protruding upwards ends in the area of the fourth side of the rectangle with rounded corners in the floor of the storey.

In Fig. 1 you can see a floor tower, which is composed of a plurality of floors 10 and four spacers 12 between successive floors 10.

2 shows the lower end of a spacer support 12 in the ready-to-engage position with respect to a floor 10. At the lower end of the spacer 12 an inner angle element 14 is attached, which faces an outer angle element 16 on the floor 10. The inner angle element 14 is formed by the shaft 12a of the spacer support 12 and by horizontal extensions 12b and 12c. The outer angle element 16 is part of a surrounding flange 18 which runs along the edge of the floor 10 and protrudes up and down.

On the inner surface 16a of the outer angle element 16, engagement cams 20 are attached, which are intended for engagement in engagement recesses 22 on the outer surface 14b of the angle element 14. Stop strips 24 are attached to the outer angle element 16 and form stop surfaces 24a. The inner angle element 14 has end surfaces or counter abutment surfaces 26 which are intended to abut against the abutment surfaces 24a.

In Fig. 3, the inner angle member 14 is inserted into the outer angle member 16 so that the outer surface 14b of the inner angle member 14 abuts the inner surface 16a of the outer angle member 16 and the engagement cams 20 of the outer angle member 16 into the engagement recesses 22 of the inner one Engage angle element 14. Due to the engagement of the engagement cams 20 in the engagement recesses 22, the spacer 12 is secured in the height direction relative to the floor 10. 3 is only possible by uncoupling the one or the other of the extensions 12b, 12c in the direction of arrow B, as shown in FIG. 3, so that the end face 26 emerges from the juxtaposition to the abutment surface 24a and then the inner angle element 14 can then be turned out of the outer angle element 16 in the direction of arrow D and can be completely uncoupled. The installation of the inner angle element 14 into the outer angle element 16 takes place in such a way that the inner angle element 14 is placed with the end surface 26 located at the bottom right against the stop surface 24a and the extension 12b is then pressed against the stop bar 24 via the stop bar 24 pushes away until the end surface 26 engages behind the stop surface 24a.

For even better stability, engagement formations similar to the engagement cams 20 and the engagement recesses 22 can also be provided in the apex region S between the outer angle element 16 and the inner angle element 14. However, if the angle element 14 is fitted exactly into the angle element 16, so that both end surfaces 26 abut exactly against the stop surfaces 24a and the surfaces 14b and 16a also abut each other at the same time, the elements shown in FIGS. 2 and 3 are sufficient for stability the clutch.

It should also be noted that the engagement cams 20 and 20a in FIG. 2 are therefore offset from one another in the direction of the curved line C in order to simplify the production by casting. The slot 21 in the floor 10 serves the same purpose.

The bending of the leg 12b in the direction of arrow B in FIG. 3, which is necessary for the removal, can be brought about in particular by approximating the right angle of the shaft cross section 12a in the direction of an acute angle, as indicated by the bending arrows P in FIG. 2. It is therefore not even necessary to detach the connection by engaging a blade between the inner angle element 14 and the outer angle element 16. This measure will only be used if the shafts 12a of the spacer supports 12 are particularly strong.

4, two successive floors 110 are connected to each other by two spacers 112. The spacer supports 112 have the cross section of semicircular channels and are raised in apse-shaped bulges in the middle of two opposite sides of the floor shelves 110 taken. The connection of a spacer 112 to a floor 110 is shown in FIG. 5. One end of the spacer 112 here forms an inner arch element 114, while the edge flange 118 forms an outer arch element 116 in the area of the apse-shaped extension. On the inner surface 116a of the outer arch element 116, engagement cams 120 are formed for height-securing engagement in engagement recesses 122 on the outer surface 114b of the inner arch element 114. The outer arch element 116 has at its ends stop strips 124 with stop surfaces 124a, opposite which end surfaces 126 of the inner arch element 114 stand.

To uncouple the inner arch element 114 from the outer arch element 116, the inner arch element is compressed in the direction of the arrows SS so that at least one of the end surfaces 126 can pass the stop surface 124a, whereupon the inner arch element 114 is completely rotated from the outer arch element by a rotational movement 116 can be uncoupled.

FIGS. 6 and 7 again show the circumferential displacement of the engagement cams 122 and 122a and the slots 121, which have been chosen with the simplest possible shapes with regard to the casting production.

8 to 10, the spacer support 112 is shown, namely with the engagement recesses 122 and the end faces 126. The end faces 126 are set back slightly in relation to the longitudinal edges 127.

In both embodiments, the height of the curved or angular elements in the generatrix line direction H is of course responsible for the stability and also the extension of the Angle or arc elements in the direction of curvature C. The more precisely the arc or angle elements are worked, the smaller the dimensions in the generatrix line direction H and in the direction of curvature C.

11, a floor 210 has an edge flange 218 which forms an inner angle element 216. An outer angle member 214 is formed on a spacer 212. The spacer 212 stands on a standing ledge 230, which is formed in the level of the floor 210 on the outside of the edge flange 218. The angle element 214 is provided with a slot 232 in the apex region S. Cams 236 are attached to the outer angle element 214, specifically two cams 236 in the region of the ends of the outer angle element 214 and a further cam 236 near the apex. Corresponding recesses 238 are provided in the inner angle element 216, into which the cams 236 engage. The stop surfaces 236a engage behind the counter-stop surfaces 238a, which are both undercut. Instruction bevels 236b are also attached to the cams 236, which facilitate the push-button-like pressing of the cams 236 into the recesses 238. When the cams 236 are pressed into the recesses 238, the slot 232 is temporarily elastically spread until the undercut stop surfaces 236a come to rest against the possibly undercut counter-stop surfaces 238a. By means of the cams 236 and the recesses 238, the angle element 214 is secured against vertical lifting off the base strip 230. The interaction of the three cams 236 and the three recesses 238 also ensures that the spacing supports 212 are prevented from tilting relative to the floor 210. The inherent elasticity of the angle element 214 around the apex line S additionally ensures that the cams 236 cannot detach from the recesses 238. To solve it, it is rather necessary that the arch element 214 is bent in the direction of Arrows PP and that at the same time the undercut stop surfaces 236a are forced out of the undercut stop surfaces 238a, the slot 232 being able to spring open again.

13 shows a recess 238, a cam 236, the undercut stop surface 236a, the undercut counterstop surface 238a and the guide bevels 236b and 238b on an enlarged scale.

In Fig. 14, a floor tower consists of rectangular floors 310 and two spacers 312 in two adjacent corners of the floors 310. The spacers 312 each have two legs of different leg lengths, namely the legs 312a and 312b. Inner angle elements 314 are attached to the ends of the spacer supports 312 and are attached to the inside of outer angle elements 316 of the edge flange 318. The legs 312b lying in the area of the short rectangle sides are longer than the legs 312a lying in the area of the long rectangle side. In this way, the spacer brackets 312a reach in the horizontal direction relatively close to the front corners 340 of the storey floors 310 which do not have any spacer brackets in FIG. 14. The edge flange 318 only extends downward on the front rectangular side 342, downward and upward on the other rectangular sides of the shelves 310. The edge flange 318 runs out in the area of the front side of the rectangle 342 via bevelled corners 344 and 346 into the floor 310. In the legs 312b, the spacer supports are designed with vertically elongated openings 348. The spacer supports 312 are stiffened by ribs 350. At the ends of the spacer supports, as can be seen from FIG. 15, inner angle elements 314 are attached, which have rounded end surfaces or counter-stop surfaces 326 for undercut engagement with stop surfaces 324a of stop strips 324.

Cams 320 are attached to the outer angle element 316, which engage in recesses 322 of the inner angle element 314 and thus take over the height and tilt protection. It should be noted that a pair of cams and recesses 320, 322 is attached near the free end of the long leg and a further pair of cams and recesses 320, 322 near the apex S. The inner angle element 314 again has a slot 332 near the apex. In order to reinforce the recess which opens into the slot 332, it is provided with a cover 323.

The assembly and disassembly is carried out in the manner described with reference to FIGS. 2 and 3, with an additional securing of the engagement between the counter abutment surfaces 326 and the abutment surfaces 324a being ensured by their undercut shape and by the elasticity emanating from the slot 332, which is necessary for this ensures that the counter-abutment surfaces 326 - once they are snapped behind the abutment surfaces 324a - remain in pretension against the abutment surfaces 324a.

The term “line of curvature” was also used in FIG. 2 for the kink line that can be seen there. The line of curvature should therefore include both the line of curvature in the actual sense (FIG. 5, item 116) and the crease line (FIG. 2, item 16).
