Easily Disassembled Furniture

The invention is directed to easily disassembled furniture, for example, a shelf of, in particular, corrugated board or a similar foldable material, with essentially upright sidewalls, as well as a furniture corpus comprising a rear wall and with transverse mounting parts, such as insertable bottoms, which can be supported at the sidewalls, can be inserted preferably in sidewalls slots and have angular, added edge pieces.

In such furniture of the previously used type, which forms a shelf with drawers, the whole of the shelf corpus is formed by a single corrugated board blank, which in each case has two main sidewall areas, which can be folded down or in. Slots, into which the angular, added edge pieces of insertable bottoms can be inserted are provided at the surfaces, which form the inner sidewalls in the assembled state. A lid-shaped cap part, which regionally overlaps sidewalls or the front edges of the front and back sides, can be placed from above on the shelf corpus. Admittedly, aside from the insertable bottoms that are to be provided, said cap part provides the furniture a certain stability. On the whole, however, this stability leaves much to be desired. On the whole, this furniture is unstable and not in a position to be exposed to higher loads.

It is an object of the present invention to provide easily disassembled furniture particularly from corrugated board or similar foldable material of the initially named type, for which the furniture parts to be provided can be fixed to one another securely with improved overall stability.

By means of the holding safeguard, which is to be fixed to the transverse mounting part, the rear wall is braced with the transverse mounting part as well as, by way of the attachments of the transverse mounting part on the sidewall, with the latter. By these means, sidewalls, rear wall and transverse mounting parts can be fixed to one another in a stable manner with extremely little expenditure for construction and assembly and without requiring additional, supplementary attachment devices, which can be loosened only with increased handling expense during assembly and disassembly. In addition, owing to the fact that the parts are securely fixed, the load-carrying capacity is increased significantly and the tilting stability of the furniture is improved substantially, so that this furniture, when constructed as a shelf, for example, can be subjected to a load largely to the same degree as conventional furniture, which is produced from wood.

For a further explanation of the invention, reference is made to the following description as well as to the drawing. The following is shown in diagrammatic representation in the drawing.

FIGS. 8 and 9 show the blanks for constructing the lid part of the example of the operation of FIGS. 1 to 3.

The furniture, generally labeled 1 in the drawing, is constructed in the example of the operation shown as a shelf, which can easily be disassembled and has a corpus of sidewalls 2 and 3, of a real wall 4, as well as of a lid 5. The sidewalls 2 and 3, as well as the lid 5 are constructed in three layers. On the other hand, the rear wall 4 consists of only one layer of corrugated board. The rear wall 4 has angular added edge pieces 6, which can be inserted from the rear into open recesses 7 of the sidewalls 2 and 3. This is also illustrated in greater detail in FIGS. 4 and 5, which show the corrugated board blanks of the rear wall 4 and of the sidewalls 2 and 3. The blank in FIG. 4 has fold lines 2x and 2y about which the blank is folded to form the three-layer side walls 2 shown in FIG. 2. The inner layer 2a or 3a of the sidewalls 2 and 3, which is facing the interior of the corpus in the assembled state, in each case has two added edge pieces 8 (FIGS. 1, 2 and 4), which extends upwards and are to be inserted in the corresponding recesses 9 of the lid 5.

As is illustrated in particular also in FIGS. 8 and 9 of the drawing, the lid 5 consists of a blank 5a, which is to be folded in accordance with the broken lines. In the assembled state, the folding-type blank 5a forms a covering for the lid to limit an inner 3-layer corrugated board 5b, as shown in FIG. 9. The inner board blank can, however, also be constructed in two layers and be enveloped by cardboard, which, in turn, is provided with a printed sheet.

In example 3 of the operation shown, the inner layer 2a or 3a of the sidewalls 2 or 3, which faces the interior of the corpus in the assembled state, has in each case sidewall slots 10 (FIGS. 2 and 4), which are disposed one above the other and adjoining which there are window-shaped accommodating spaces 11 (FIGS. 1, 2 and 4) in the middle layer 2b and 3b in the assembled state. Into these accommodating spaces 11, essentially congruently constructed added edge pieces 12 (FIGS. 2 and 6) of transverse mounting pieces 13 forming insertable bottoms are to be inserted in such a manner, that they are bounded and, with that, held securely on both sides by corrugated board layers and also towards the top by the inner corrugated board layers 2b or 3b.

As shown by FIGS. 6 and 7, a transverse mounting part 13 is also formed by a foldable covering 13a as well as an inner layer 13b, on which there are the added edge pieces 12. Corresponding to the number of transverse mounting parts 13 that are to be provided in the example of the operation, three rear wall slots 14 (FIG. 5), which are disposed one above the other and into which the edge expansions 15 that are provided on the transverse mounting parts 13 are to be inserted, are provided in the rear wall 4. In cross section, the rear wall 4 has a triangular shape that is open towards the rear, so that a rear indentation is formed. The, in the assembled state, rear regions, which adjoin the edge expansions 15 of a transverse mounting part 13, expand at an angle towards the outside and therefore, in the assembled state, follow the course of the triangular cross section of the rear wall 4, so that, outside of the edge expansions 15 that are inserted through the rear wall slots 14, the rear wall 4 ends flush. In the assembled state, the edge expansions 15 have insertion openings 16 in coaxial arrangement. Into these insertion openings 16, a holding safeguard 17, which is constructed, for example, as a wooden rod and which in the assembled state acts upon the rear wall with a gripping power, can be inserted. Taking into consideration the elasticity of the corrugated board chosen in the example of the operation, the parts are designed so that, when assembling the rear wall or the transverse mounting parts, the added edge pieces 12, which are inserted in the sidewalls slots 10, are movable in a particular manner in such a way that the holding safeguard 17 can be mounted and, when mounted, exerts the desired holding force on the rear wall. With that, a holding force, which acts upon the rear wall 4 and the sidewall parts 2 and 3, is also exerted over the added edge pieces 12 in the sidewall slots 10 on the side wall parts 2 and 3. With that and despite of the furthermore existing possibility of once again disassembling the furniture parts with only a few manipulations and without expending much force, the individual parts are connected together securely with the advantage that the furniture is stable and shows no tendency to topple over and can also withstand higher loads. Aside from a rod-shaped holding safeguard, it is of course also possible to provide other holding safeguards, which can be fixed to the transverse mounting parts and act upon the rear wall in an analogous manner with an appropriate holding force. Such other holding safeguards, for example in the form of toe dog components, etc., act upon the rear wall in an analogous manner with an appropriate holding force. By means of the added edge pieces 8, recesses 9, etc., which have been provided, individual furniture elements of the aforementioned type can be strung together almost at will, optionally with the help of suitable connecting elements, stacked and fixed to one another, so that furniture of different height and length, shape and design can be assembled in a technically simple manner.
