Description

The present invention relates to a shelf of a foldable sheet material such as cardboard, corrugated cardboard or the like according to the preamble of the main claim.

Cardboard shelves, for example, are used as stalls in shops and offer the advantage of a low weight due to the material used and high stability. Such shelves are already known from the prior art.

The publication DE 20 2008 017 213 U1 discloses z. B. a generic shelf with two carriers made of cardboard, in the shelves have tabs that are inserted into slots in the carriers and thus hold together the shelf. To increase the available area of the shelves, such shelves are attached to each side of the shelf. Such a structure has the disadvantage that a plurality of shelves mounted separately in the carrier and in each case more tabs must be inserted into the respective slots, which can be time consuming the composition of such a shelf.

The present invention is therefore based on the object to develop a shelf that avoids the disadvantages mentioned, which should therefore be easy to assemble and disassemble, the assembled shelf should convey the most transparent and less massive impression.

This object is achieved by a shelf with the features of the main claim.

The proposed shelf consists of a bendable sheet material such as cardboard, preferably corrugated cardboard, and comprises two carriers and at least one shelf held by the carriers. Each of the carriers has in each case a rear wall and two opposite the rear wall angled side walls. The shelf is pushed horizontally through both rear walls and is located on a lower edge of an opening in each of the two rear walls. A not filled from the shelf part of said openings is closed by a connected via a crease line with the respective rear wall flap. This flap can be opened to push the shelf through the opening. When the shelf is inserted, one edge of the flap lies flush on top of it.

Such a shelf can be set up very easily in an advantageous manner, since it is assembled by simply pushing the shelf through the openings in the two carriers. For this it is not necessary to insert tabs in slots, which greatly simplifies the structure. In addition, the shelf is aesthetically pleasing, since the openings required for assembly are closed again by the flaps. Due to the flush resting of the flaps on the shelf also the shelf is pressed so on the lower edge of the respective opening that he practically can not move, so that the structure is very stable. Finally, the shelf can be made very transparent, because the at least one shelf is held by the rear walls of the carrier, so that the side walls can be made very slim. By using cardboard or similar bendable material, the weight of the shelf is low, and because of its low weight and easy assembly and disassembly, the shelf is easy to transport.

Advantageous developments are described in the subclaims.

The side walls are preferably connected in each case via a bending line with the rear wall. Typically, they each comprise two superimposed layers, which are connected to each other via other creases. Preferably, a further layer is applied to the rear wall of the carrier as a reinforcing layer, which increases the stability of the rear wall.

In an advantageous embodiment it can be provided that the rear wall of at least one of the carriers has at least one web pointing into the opening at the lower edge of the opening. The shelf has in this case at least one the web receiving recess. By projecting into the recess of the shelf web shelf is then stationarily positioned relative to the carrier and is held in a defined position.

Alternatively or additionally, the flap may have at least one tongue at a lower edge, which protrudes into a recess in the shelf. As a result, the flap is held in a defined position, which additionally contributes to the fixation of the shelf because of the pressure applied to the shelf by the flap.

Provided both at the bottom of the opening of the opening in the opening facing web as well as at the bottom Edge of the flap attached tongue are provided, the web and the tongue can be arranged opposite to each other, wherein the recess into which the tongue protrudes, then with the web receiving recess is identical. As a result, only one recess for receiving both elements is needed, which increases the stability of the reason why not so many places broken open shelf.

Preferably, a total height of the opening exceeds a maximum height of the shelf. The total height of the opening typically corresponds to the sum of a thickness of a base of the shelf, optionally including a reinforcing ply thereon, and a height of the non-shelf-filled portion of the opening. As a result, additional space is created in the opening when the flap is opened, which facilitates the passage of the shelf through. In addition, it may be provided that the opening has a width which corresponds to a width of the shelf and typically extends over the entire width of the rear wall. As a result, the shelf is also flush with the side, which increases the stability of the shelf and looks aesthetically pleasing.

An embodiment may provide a fixing device for temporarily holding the flap in an unfolded state on the rear wall. The flap can thereby be kept open in the construction of the shelf, so that it does not obscure the opening during insertion of the shelf, and is prevented even when no hand is free to keep the flap open. This facilitates the insertion, especially if the shelf of a single person to be kept alone.

In a particularly advantageous manner, the fixing device may comprise a latch, which is introduced into mutually corresponding apertures on the flap and the rear wall. The bolt can this consist of the material from which the shelf is made. By inserting the bolt into the apertures of the flap and the rear wall which lie one above the other in an unfolded state of the flap, the flap is held in the unfolded state by latching forces acting between the latch and the flap or between the latch and the rear wall.

The shelf may have a base and one at an edge of the base attaching and opposite the base angled aperture. The panel may be formed by at least one winding profile, which comprises at least two mutually folded layers of the sheet material. Abutting and each formed by one of the winding profiles sections of the panel can be interconnected by a introduced in at least one of these winding profiles connecting plate. The bezel offers the advantage that objects stored on the shelf are secured against falling off the shelf. Due to the winding profile, such a panel is easy to manufacture, has a high stability and can also be easily disassembled again. The connecting strap between the individual sections of the winding profile allows a very simple yet mechanically stable connection thereof. It can be connected via a bending edge with the winding profile of one of the sections connected by them. Preferably, the footprint of four sections of the aperture framed, which are accordingly connected by a total of four connecting tabs. In the same way as the shelf described can also be designed a shelf, ie also the shelf foot can have a base and an opposite the base angled aperture of the type described.

In addition, it can be provided that the winding profile is held together by a resting on the base surface of the shelf reinforcement layer. The winding profile is thus prevented from unfolding, without the tongue profile even more tongues or splices must be provided, which simplifies the structure. In addition, the reinforcing layer increases the mechanical stability of the base of the shelf, so that even heavier objects can be stored on it.

Furthermore, the flap can be recessed laterally so that it leaves the panel space and rests top and side of the panel. Even if the opening is higher than the aperture, the flap thus completely covers the not filled from the shelf with the panel part of the opening and fixed by additional support surfaces between the flap and the shelf this fixed with respect to the rear wall. Also, the flap thereby holds the winding profiles together, which form the parts of the panel projecting through the opening, and prevents them from automatically unfolding.

In one embodiment, the shelf may have a shelf foot on which both carriers stand. The shelf foot simplifies the positioning of the two carriers to each other and thus stabilizes the entire Shelf.

Furthermore, it can be provided that at least one of the side walls of the carrier is connected by a connecting element with the shelf foot, wherein the connecting element is wrapped in a winding profile. The winding profile can form a shelf of the closing foot of the shelf foot. The connecting element is preferably designed T-shaped and may have a tab which is guided through a slot on a bending line of the winding profile and is pushed with one end into a further slot located in the side wall. The connecting element connects the shelf foot in a simple manner with the respective carrier mechanically stable, so that the carrier relative to the shelf foot is held in a defined position and can not accidentally slip.

For attachment to a pallet, the shelf foot may have at least one fixing loop for kinking out of the base of the shelf foot and for laying around a board of the pallet. The shelf foot can then be connected by the fixing loop mechanically stable with a pallet. A transport of the assembled shelf can then be done in a practical manner by moving the pallet, wherein the fixing loop prevents falling from the pallet or slipping on the pallet.

It can be provided that the side walls of at least one of the carrier are braced against each other by at least one connecting piece, which has a tab at two opposite ends in each case. The tabs can each be arranged in a same height with the lower edge of the opening Slit be inserted in a position in one of the side walls, so that the shelf rests on the connector. The connector holds the rear wall and side walls of the carrier in a defined position to each other and thus secures them against unfolding. Due to the additional support surfaces for the shelf this is also stored more stable.

The shelf or each of the shelves may have at least one slot in which a partition is inserted in the vertical direction to form separate compartments on the shelf or the shelves. At the edge of the partition while one or more recesses may be predetermined, with which the partition can be hung at the end of the slot in the respective shelf. As a result, the dividing wall, which typically extends through a plurality of shelves, can be kept at a predetermined height.

In one embodiment, it may be provided that the shelf has male members for insertion into corresponding slots of the carrier, wherein the male members are designed as tabs, which are each connected via a first crease line to the shelf, and a second crease line for angling each one into a Having the slots to be inserted tab end. As a result, the shelf is additionally connected to the carrier and secured against this against accidental slipping.

The in FIG. 1 shown shelf has a height of about 1.5 m. The shelves 2 have a length of about 1.1 m and a width of about 70 cm. The carrier 1, the shelves 2 and the shelf foot 4 are formed from various blanks of corrugated cardboard, which are folded over along various bending lines. For bend lines, around which the respective blank is bent particularly far, scoring lines can also be provided instead of the fold lines be.

FIG. 2 represents a further embodiment of a shelf according to the invention in one FIG. 1 corresponding side view. Recurring features are here and in the following figures each again provided with the same reference numerals. From the embodiment FIG. 1 the shelf is different FIG. 2 merely in that the side walls 3 have a shape which tapers towards a point.

In FIG. 3 is in a corresponding representation of the shelf FIG. 2 similar shelf shown. In the embodiment shown here partitions 7 are additionally inserted through all shelves 2 in the vertical direction, forming the separate compartments on the shelves 2. The partitions 7 have different shapes. Some are rectangular, others are bevelled at the top. Like the other components of the shelf, the partitions 7 are made of corrugated cardboard.

FIG. 4 shows the example of the shelf FIG. 2 how the shelf is constructed by pushing the shelves 2 through the carrier 1. The rear walls 8 of the carrier 1 each have three openings 9, of which two in each case two rear walls 8 are arranged at the same height and have the identical dimensions. The shelves 2 are inserted horizontally into the openings 9 and pushed through both rear walls 8. The bottom shelf 2 is in the in FIG. 4 shown half-built state of the shelf already pushed through both rear walls 8 and is located on a lower edge in each case an opening 9 in each of the two rear walls 8 on. The middle and the top shelf 2 are each only pushed through one of the openings 9. Each of the openings 9 of the rear walls 8 has a flap 10, which is connected via a bend line 21 with the respective rear wall 8. When the shelf is finished, a not filled by the respective shelf 2 part of the openings 9 is closed by the flap 10. For pushing the shelves 2 through the openings 9, the flaps 10 are hinged. After pushing through the shelves 2, so if these each rest on a lower edge of two of the openings 9, the flaps 10 can be closed again, in such a way that a lower edge of each of the flaps 10 rests flush on the shelves 2.

In FIG. 5 is a perspective view of the same shelf in the in FIG. 4 shown state shown. Here is easy to see how the shelves 2 are pushed horizontally through the openings 9. Evident are also the rear walls 8 of the two carriers 1 and the standing at right angles to the respective rear wall 8 side walls 3. In plan view, the carrier 1 and the angled side walls 3 thus form a U-shaped profile. Each of the side walls 3 is formed in two layers, so there are two layers of cardboard on each other and thus form the side wall 3. The individual layers are connected by creases, each of the side walls 3 is connected via a fold line with the rear wall 8. Three of the flaps 10 for closing the openings 9 are opened here for pushing the shelves 2, three more shown in a closed state. At a lower edge of each of the openings 9 two pointing in the respective opening 9 webs 11 are mounted, wherein the shelves. 2 the respective webs 11 receiving recesses 12 have. Two of these webs 11 are in FIG. 5 to recognize, while the rest of the shelves 2 are covered. Each of the flaps 10 has at a lower edge two tongues 13, which protrude into the same recesses 12 in the shelf 2. The tongues 13 and the webs 11 are arranged opposite each other and abut halfway up in the recesses 12 to each other. The shelves 2 are held by the webs 11 in their position while the tongues 13 hold the flaps 10 in the closed state, so that the flaps 10 press on the respective shelf 2 and in turn prevent this from dislodging.

Each of the shelves 2 has a base area 14 and an aperture 15 which adjoins an edge of the base area 14 and is angled relative to the base area 14 by 90 °. In the base 14 in each case a total of four of the recesses 12 are provided which have identical dimensions and each receive one of the webs 11 and one of the tongues 13. The panel 15 has four sections which frame the base 14 around. Each of these sections is formed by a winding profile, which comprises two or three mutually folded layers of the shelf 2 forming corrugated board. The flaps 10 are laterally recessed so that they leave the panel 15 of the shelves 2 space and rest not only on the respective base 14, but also above and on the side of the panel 15.

The panel 15 of the shelf is formed in a similar manner as the peripheral panels 15 of the shelves 2. The side walls 3 of the carrier 1 are disposed within the aperture 15 of the shelf foot 4, wherein the Aperture 15 of the shelf foot 4 prevents the side walls 3 from unfolding.
