Snap-together shelf

909837 / $ 001

The invention relates to a plug-together shelf, consisting of at least four shelf posts made of angle rails, each have in one of the two legs spaced one above the other holes, inserted into the plug-in organs that carry rectangular or square shelves.

A variety of interlocking shelves are known. Usually such shelves are made up of four posts, which consist of angle rails, with holes arranged one above the other being drilled into one leg of the angle rails, through which, for example, screws are inserted on which the shelves rest »The disadvantage of such constructions is that the shelf ladders have to be screwed awkwardly with the shelves. Furthermore, the Shelf ladders must be connected to one another.

The invention is based on the object of creating a plug-together shelf of the type mentioned at the outset, which Can be plugged together without screws, whereby the entire shelf with the insertion of the shelves is completely fixed and should be torsion-resistant without the shelves being able to loosen. Furthermore it should be superfluous that the shelf posts are additionally held in pairs, one below the other, the stability of the shelf should be by itself the shelves are installed.

909837/0011

The solution to this problem is that according to the invention the holes within one leg of the angle rails are elongated holes that are inclined at an angle from top to bottom run towards the common outer edge of the angle rails and that the shelves each have a rear and a front Have bevel, in their lateral ends in the area that the leg of the angle rails having the row of slots overlap, bores are arranged through which and at the same time through the elongated holes the plug-in organs are inserted are used to clamp the shelves.

The pluggable shelf according to the present invention has the salient advantages over known shelves of the prior art that with the installation of the shelves and the insertion of the plug-in organs through the holes in the folds and through the elongated holes within the shelf posts, a stiffening between the shelf posts and the shelves takes place . Due to the obliquely running elongated holes, the shelves are pressed a little downwards and inwards within the angle rail towards the other leg of the same. The higher the load on the shelf, the greater this tension, so that the stackable shelf according to the invention becomes even more stable under load in a highly advantageous manner. The length of the elongated holes and the inclination of the same are coordinated in such a way that the stop of the edge of the shelf on the other

909837/0018

ren legs of the angle rail occurs approximately when the plug-in element is approximately in the lower third up to lower quarter of the elongated hole.

In a highly advantageous and preferred embodiment the elongated holes are formed like a keyhole with an upper round hole and an obliquely inclined slotted hole, wherein the plug-in members are clamping bolts which have heads at both ends, one of which has a smaller diameter possesses than the clear diameter of the round hole and the holes within the folds of the shelves. Through this is achieved in an advantageous manner that the entire Assembly of the snap-together shelf according to the invention completely without any screw and without any nut. That's why you don't even need a wrench for assembly and a screwdriver is needed. The only parts that need to be put together are the same ^ formed Shelf posts for right and left, back and front, identically designed shelves and identically designed clamping bolts. Therefore, the assembly of the shelf according to the invention is simplified in the simplest possible way, there can be no mix-ups of the individual parts come more from one another. Since the clamping bolts have heads that have a different Have diameter, with the smaller head at the same time through the hole within the fold and through the Round hole of the keyhole can be inserted, the

909837/0018

2608855

The shelf is simply held by the clamping bolt when the load is applied and due to the incline of the elongated hole against the other Leg of the ¥ angle splint pressed on. The two heads of the clamping bolts have a diameter that is larger, however, than the clear Veite of the slot hole, so that after inserting the smaller head of the clamping bolt through the Hole within the fold and through the round hole of the clamping bolt in an advantageous manner within the keyhole is held captive and secured against falling out.

In a further embodiment according to the invention, the shelves Along the rear longitudinal edge to have an upstand which is folded over and which merges into the fold. Through this a stop for example for files or books is achieved in an advantageous manner, so that the same do not can be pushed out over the shelf.

Furthermore, the shelves can be along the front longitudinal edge have a bulge that merges into the front fold. This prevents, for example, round or roller-shaped objects can roll down from the shelf to the front.

In a further, advantageous embodiment, the individual Shelf with lateral folds, whereby the longitudinal folds in the shelf level over the lateral folds.

⁰ I.

protrude or run flush with them. In the projection Seen on the shelf level, the longitudinal bevels protrude beyond the lateral folds or run at least flush with them, which is extremely advantageous a defined stop of defined length is achieved. The stop is therefore usually formed by the lateral, narrow front edge of the longitudinal folds.

In addition, it is possible to reinforce very high shelf posts by means of cross-wise reinforcement struts in addition to bracing.

The struts can be guided either inside the angle rails or outside the same. Are the stiffening struts guided within the angle rails, in the legs that do not have the rows of elongated holes, Slots arranged vertically near the inner longitudinal edge of the angle rails, through which the stiffening struts with their ends are inserted, which have a hole in the free end protruding through the leg that a locking pin is inserted.

In a preferred manner, the stiffening struts are applied to the angle rails from the outside and are connected to them have the legs of the angle rails having the rows of elongated holes near the inner edge of the same perpendicular

909837/0018

Slits through which the right-angled ends of the cross-wise stiffening struts are inserted are, wherein the inserted through the slot, free end of the stiffening struts has a hole through which a locking pin is plugged. The locking pin can be designed to be slightly chonical, so that it is clamped in the hole is.

The invention provides a pluggable one in a highly advantageous manner Shelf available, which increases in stability and torsional stiffness when the shelf is loaded, since the shelves are increasingly braced in the shelf posts or the shelf ladders as the load increases.

For multiple shelves, the middle shelf posts or shelf ladders can be replaced by double shelf posts, whereby these have two parallel rows of elongated holes or keyhole-like holes, wherein the elongated holes or the slotted holes of the keyholes are inclined downwards towards each other. Then in more advantageous Way, double the number of shelves can be held at the same time by such a double shelf post, in order to bridge larger lengths of the shelves. Another advantage is given by the fact that a continuous, long shelf surface can be produced 'can be formed due to the abutting, individual shelves.

Figure 11 is a plan view from above of a shelf post with Shelf and a stiffening strut, velche is bent at its end and through a slot is inserted within one leg of the ¥ angle rail and provided with a locking pin.

According to FIG. 1, an exemplary embodiment of the plug-in shelf according to the invention consists of four shelf posts 1, 2, 3 and k, which are angle rails bent at right angles with legs * »3» M or h5, k6 . Between the shelf posts 1, 2, 3 and k , shelves 5 are arranged, which can be arranged at any height. The rear shelf posts 2, h are additionally stiffened by means of cross struts 6, 7 which are held together at a crossing point 8 by a rivet or by a screw.

The shelf posts 1, 2, 3 »^ have in one of the legs Uj or h5 one above the other at the same intervals, keyhole-shaped elongated holes 9» 10, which consist of a round

909837/0018

Hole 15 and an inclined slotted hole ^ 6 exist. The slotted holes - and thus the keyhole-like elongated hole - are so inclined downward towards the outer edge 11 or 12 of the ¥ inkelschiene 1 or, 2 that the centers of the round hole 15 and the lower end of the slot hole 16 in the vertical plan view a small distance a according to Figure 1 have.

In order to understand the clamp mounting of the shelves 5, FIG. 5 will now be discussed. The shelf 5 consists of the shelf level or shelf surface, which has a fold 13 along the rear longitudinal edge and a fold 22 along the front longitudinal edge. Within these bent portions are located in the side ends thereof overlap to the long row of holes having legs of the mounting brackets in the range holes 17. In order to mount the shelves 5 in the shelf conductors 1, 2 or 3, h is now through the holes 17 of the bevels 13 or 22 from the inside clamping bolts 1 * 1 (Figure 3 and * t) inserted through, these being simultaneously inserted through the round holes 15 of the keyhole-like elongated holes 9 »1o.

The clamping bolts 1 * 1 consist according to the figures 3 »* ♦ from one Bolt piece 2o, which has a head 18, 19 at each of its two ends. The two heads have different ones Diameter, where the diameter of the smaller head is 18

909837/0018

2608855

is slightly smaller than the clear diameter of the holes I7 and the round hole 15. Furthermore, the smaller one has a head 18 a circumferential bevel 21 for easier introduction of the Through the holes I7 and the round holes 15

After the smaller head 18 of the round bolt 1 * ί has been inserted through the hole 17 and through the congruent round hole 15 of the keyhole-like hole 9 or 1o, the bolt piece 2o slides, which has a slightly smaller diameter than the free one , smaller diameter of the slotted hole, lengthways into the slotted hole 16. Due to the obliquely outward inclination of the slot hole towards the outer edge 11 or 12, the clamping bolt Ik therefore leads downwards and slightly outwards by the distance a according to the Tigur 1, whereby the shelf 5 is also lowered slightly downwards, but at the same time the shelf moves outwards to rest on the other leg kk or U6 , namely just by the distance a in Figure 1. The clamping bolt has regularly reached its end position in the last third to the last quarter of the length of the slot hole 16, so that when the shelf 5 is loaded, the clamping bolt 1Ί can move further downwards and outwards at the same time. As a result, the tension between the shelf ladder 1, 2 and the shelf 5 grows at the same time, because the shelf 5 is also moved downwards when loaded, inward on the other leg of the angle rail.

909837/0011

2608855

According to FIG. 6, the shelf has an upstand 3 ** »which is folded over along its rear longitudinal axis and which merges into the fold 13 downwards. This upstand 3 ^ in front of the fold 13 is used to create an end limit of the shelf 5 »so that objects placed on the same cannot be pushed out over the shelf. Furthermore, it can be seen from Figure 6 that the shelf 5 also has bevels 26 on the side. The longitudinal folds 13 »22 of the shelf 5 protrude in a plan view the lateral folds on the shelf level, which can be seen in particular from FIG. 7; at least they run The end edges of the longitudinal folds are flush with the lateral folds. This ensures that preferably only the the front edges of the longitudinal folds form the stops within the shelf posts, so that due to precisely specified Length of the shelf a precisely defined stop of the same can be achieved within the angle rail.

Figures 7-8 and 10 show enlarged sections, according to the circles A, B and C in Figures 5 and 6. According to Figure 7 it can be clearly seen that the front edge or the front end k2 of the rear longitudinal fold 13 is the lateral fold 26 of the shelf 5 protrudes so that when the shelf is inserted into the shelf ladder, only this edge U2 of the rear longitudinal fold 13 strikes against the leg kk or k6 (FIG. 1).

909837/0018

It can be seen from FIG. 8 that the front longitudinal fold 22 of the shelf 5 has a bulge 23 along the upper longitudinal edge of the shelf which merges into the fold 22. The fold 22 has in its lower region a part 2k which is bent back at right angles and which in turn merges into an end part which is bent up at right angles. The rear longitudinal fold 13 is designed in a similar manner, which merges into a part 35 bent back at right angles, which has an end part 36 bent upwards at right angles. Furthermore, it can be seen from FIG. 1 o that, before the start of the longitudinal fold 13, the shelf 5 has an upstand 3 ^ along its rear longitudinal edge, which is folded over and merges into the longitudinal fold 13. Furthermore, the lateral folds 26 have horizontally arranged longitudinal slots 371 with which, for example, by means of further plug-in elements laterally abutting shelves can be connected in several shelves lined up next to one another. "

FIG. 9 shows a partial section of a double shelf post 28 which is used when a long shelf is created shall be. This double shelf post 28 has two parallel rows of one above the other Keyhole-like holes 29 and 3o. Further the double shelf post 28 has longitudinal slots 31 »32.

According to Figure 1, all shelf posts such, vertically

have extending slots 27, 33, which for pushing through the ends of the stiffening struts 6, 7 are used.

There are two options here; either the slots 27 are located in the leg k6, which does not have the keyhole-like holes according to the shelf posts 2, 3 and k _t , in which case the stiffening struts 6, 7 run inside within one leg k $ of the angle rail, as shown in FIG 1 is also shown. In this case, the stiffening struts 6, 7 have at their ends, which again protrude through the slots 27, bores through each of which a locking pin is inserted.

The preferred embodiment, however, is the one in which, according to FIG. 11, the stiffening strut 38 is placed from the outside on the leg h3 , which has the keyhole-like holes according to the shelf post 1 in FIG. 1 and FIG. 11. In this case, the stiffening strut 38 is at right angles bent end 39 »which is inserted through the slot 33 within the leg k3. The free end 39, which is inserted through the slot 33, has a hole ko through which a locking pin * I1 is inserted, which can be of a slightly nononic design. As a result, the locking pin * »1 can simply be jammed in the hole ^ o. After inserting the locking pin kl into the hole ^ o of the stiffening strut 38, it is protected against being pulled out or falling out.
