Description

BACKGROUND OF THE INVENTION The present invention relates to a module shelf unit folded from a sheet of paper material having dual layer sidewalls, backside and load-carrying shelves, wherein the sidewalls have shelf support cutouts and the backsheet and sidewalls are folded from a single sheet.

It is known that in practice shelves made of wood, pressed plate, metal, plastic are widespread.

There are many unique and serial versions of wooden shelves. Their common feature is that high quality raw materials are difficult to obtain, and they require expensive technology to process and finish, which is why shelves are very expensive.

A shelf made of fibreboard is more economical because the fibreboard is made from wood waste, but its very heavy weight is a disadvantage in terms of transport and construction.

A critical part of metal shelves is surface protection, corrosion protection.

Many people have already tried to use paper as a raw material to create various objects. German Patent No. 3,734,767 discloses an installation made of corrugated paper. Hungarian Patent Application 1043/93 describes a piece of furniture (table, cabinet, chair and armchair) made of corrugated board. The furniture can be manufactured in series and has a wide range of products, but in this case too, it is necessary to install a wooden structure to achieve sufficient strength.

Other furniture made of paper is described in US 5,678,706, US 5,681,641, GB 2,281,586 or EP 0,166,848.

US 4,519,319 and DE 295 17 795, respectively, describe a foldable shop rack having two-layer sidewalls, backside and load-carrying shelves, wherein the sidewalls have shelf support cutouts, the backside and the sidewall being folded from a single member. The solutions presented cannot be used as furniture because they have the capacity to carry books, files, etc. not enough to hold, and shelves can easily slip out of the side walls.

The main object of the present invention is to overcome the above disadvantages and to expand the use of paper, to create industrially manufactured objects, and to reduce the adverse environmental effects by increasing the potential for reuse.

I have solved the problem by using a module shelf folded from a sheet of paper material, which has two-layer side walls, back panel and load-bearing shelves, where the inner panel of the side panels has shelf recesses, the back panel and . In accordance with the invention, straight slots at the ends of the shelf support cutouts are polygonal, the upper edge of which corresponds to the upper straight line defining the polygons, and the longitudinal edges of the shelves are inclined Dual Layer.

The ribs on the shelves and the portions of the shelf support recesses are triangular and / or rectangular, and the spacers of the side walls are rectangular.

The sidewalls are provided with bottom and / or top closure stiffening sheets, and the closure stiffening sheets are provided with closure stiffening tabs along their mating edges.

The shelf members are preferably made of laminated or corrugated paper.

The present invention can be used to create low-cost shelves that can be assembled from base components, self-supporting, self-sealing, collapsible and refoldable, all of which require low shipping and storage costs in a prefabricated sheet form.

In a preferred embodiment, the shelf member can be formed using corrugated paper, pre-fabricated with a papermaking technology such as cropping, beating, punching. There are several types of corrugated paper in terms of thickness and construction. In the plates, the waves are always mounted parallel to the wave direction as a parallel, horizontal load-bearing element, so that they can be subjected to much greater stress. And when used as a vertical load-bearing element, they can be subjected to maximum stress when the wave direction is vertical.

The invention will now be described with reference to the accompanying drawings. In the drawing it is

Fig. 4 is a partially sectional view of a shelf module, illustrated in

Figure 5 is a detail of another embodiment and a

Figure 6 is a sectional view of a detail of a further embodiment.

The module shelf elements shown in Figure 1 have different widths and heights, but each module consists of 1 and 2 side panels, 3 back panels and 4 shelves. The shelves 4 are supported by openings 5 in the side walls 1 and 2.

Figure 2 shows that both the side walls 1 and 2 and the backsheet 3 are formed of a single plate 6. The plate 6 can be folded along the dashed lines to form the side walls 1 and 2 and the spacers 1a, 1b, 2a, 2b and the locking plates 7, 8 shown in Figure 2.

The plate 6 shown in Fig. 2, as a cut pattern, comprises closure bracing tabs 9 disposed between the backsheet 3 and the closure bracing plates 7, 8. Further closure stiffening tabs 10 are provided on the closure stiffening panels 7 and 8 and are received by slots 11 when the side walls 1 and 2 are folded and closed with the closure stiffening panels 7 and 8, respectively.

Figure 3 shows that the shelves are folded from a rectangular plate to a load-bearing plate 13 and, when folded, have ribs 14 at their edges which increase the load-bearing capacity. The ribs 14 are formed by folding the plate 12 along the dashed lines so that the tubular ribs 14,

EN 219 510 Β in the middle part, the double plate 15 shown in Figure 4 is formed.

Figure 4 shows a portion of an assembled shelf member. In the embodiment shown, the shelves 4 fit into openings 5 in a straight wall 16 and two rectangular cutouts 17 in the side wall 1. It should be noted, however, that not only are the recesses 17 rectangular, but also any other shape.

Figure 5 shows, for example, triangular cutouts 17. In this embodiment, the spacer lb is not perpendicular to the side wall 1, unlike the embodiment shown in FIG.

Fig. 6 shows an embodiment where the ribs 14 of the load-bearing member 13 are in contact with one another at point 18. Shelves of this kind should be used if you want to store books, filing cabinets or similar materials in an oblique position. In this embodiment, the side wall 1 is provided with only one spacer 1a at the rear panel 3, while at the other end there is an edge 19 corresponding to a triangular cross-section.

The basic advantage of the present invention is that the furniture thus produced can be simply folded from a sheeting pattern, is aesthetically pleasing and at the same time has sufficient load capacity to be used as furniture of the same standard as traditional furniture. They are easy to assemble and disassemble, and therefore easy to store and transport.
