Description

Title: Modular system for cabinets and / or shelves

Confession

The present invention relates to a modular furniture system from which cabinets and / or shelves can be put together.

Modular systems for the production of cabinets and / or shelves are widely known. For example, cellars, garages or storage rooms are inexpensive, flexible and easy to build cabinets or shelves in demand. Often, the possibility of individual adaptation to premises plays a special role in order to be able to optimally utilize the available stand space.

It is an object of the invention to provide a modular furniture system that can be made particularly inexpensive, consists of as little as possible different items and is easy to assemble and can be easily changed if necessary.

The object is achieved in that the finished sidewalls, floors and upper end parts are made in one piece and partial surfaces of the side walls are bent several times outwards, the assembled cabinets and / or shelves have smooth surfaces inside.

All essential individual parts of the furniture system according to the invention, such as side walls, floors, shelves and ceilings, are preferably made of sheet metal, in particular sheet steel. By bending existing partial surfaces, for example. The side walls, a high stability is achieved, so that even heavy loads in the cabinet or

Shelf can be stored.

The side walls, but also the floor and the upper end part can be manufactured in only three steps, namely the - cutting of the metal sheet, - bending of the partial surfaces, - creating connection possibilities (for example holes or rectangular recesses).

The assembly of the individual parts to a cabinet or a shelf by means of fewer screw and / or connectors.

The fact that the side walls according to the invention are folded outward, results in a smooth inner surface in the cabinet or on the shelf. If necessary, for example, pull-out rails or other fittings can be hung directly into the recesses provided or screwed by means of existing holes with these. This simplifies the structure and it is predominantly shear forces and almost no bending moments introduced into the side wall. As a result, the side wall is very high load, even if the wall thickness is low.

In a preferred embodiment it is provided that the partial surfaces of the side walls are folded three times at right angles, so that along the outside of the side walls in each case a channel forms with a substantially quadrangular profile. The channel thus created gives the side wall a high stability.

The profile of the channel is also well suited to be there e.g. Use plastic feet. These feet can compensate for unevenness of the ground.

The construction of the side wall according to the invention makes it possible to usefully use the space on the outside of the side walls which forms through the channels, e.g. as a channel for an electrical supply line, a network line and / or a compressed air line.

It is also envisaged that shelves can be arranged between the side walls inside the cabinet or shelf. As a result, the interior of the cabinet or the shelf can be used optimally, in particular small parts can be stored clearly. The side walls have facilities (in particular round or rectangular openings), which allow the shelves, pull-out rails and other internals to be variably arranged in height.

The shelves, upper panels and shelves are each arranged between two side walls during assembly. Therefore, it is envisaged that the floors, finishes and shelves are largely identical. The shelves and end parts are identical. In one embodiment, the standing bottoms and upper end portions have, for example, a top surface, wherein a rectangular metal sheet is preferably bent at right angles to the narrow sides, so that two attachment surfaces form on both sides at right angles to the top surface. The floorings and end parts are thus bent substantially U-shaped. The top surface is on its longitudinal side and the mounting surfaces are each folded again rectangular at their narrow sides, so that forms a right angle to the mounting surfaces and the top surface virtually a frame. The frame sections which meet at right angles can be mitred or overlap one another. Along the miter or in the overlapping areas, the frames may be joined together (eg by riveting, screwing, gluing or welding). This increases the stability.

The frames may be particularly in the field of

Mounting surfaces have holes so that they can be bolted to other components.

The shelves are constructed very similar. The main difference is that the mounting surfaces are shorter and the frame 42 is omitted and the frame 42 'extends over the entire length of the shelf.

Only those made in the same above three steps. This reduces the Thus, the shelves can be made in the same three above-mentioned steps. This reduces the number of different components needed to assemble the cabinet or shelf. The manufacturing cost of the modular system can be reduced.

In particular, it is provided that the side walls, floors, upper end parts and shelves at defined positions have holes, so that the components can be screwed together. In addition, rectangular recesses or raised tabs may be provided to connect the components by a plug connection.

Thus, for example, the channels of the side walls at regular intervals or in a regular pattern distributed holes and / or have rectangular recesses. The floorings, upper end parts and shelves may have holes and / or raised tabs, which can cooperate with the holes and / or rectangular recesses of the channels.

When assembling the cabinet then either two holes in a screw or the rectangular recesses interact with the raised tabs in a connector.

Due to the relatively small close spacing of the bores and / or rectangular recesses (approximately 50 mm) in the channels, in particular the shelves can be arranged in almost any desired height in the interior of the cabinet. In particular, the connector is a very simple and time-saving connection option.

Other applications arise when, in particular, the bores, e.g. are arranged in the region of the channels.

Thereby it is e.g. possible to screw together two cabinets without visible and annoying screw heads. Basically, these types of connections enable a simple and time-saving assembly (and dismantling) of cabinets or shelves.

Furthermore, it is provided that shelves can be arranged between two adjacent cabinets whose length is adjustable by two telescopically movable parts of the shelves. It can be arranged between the two cabinets, several parallel shelves. By the telescopically movable parts of the shelf can be achieved, that on the one hand, the distance between the two cabinets can be used as a shelf wall. On the other hand, the cabinets must not be placed at a fixed distance from each other. The telescoping parts of the shelf can be adjusted in length so that they fit between the two cabinets. This improves the space utilization.

So that a good stability for the shelf can be ensured, the two telescopically movable parts of the shelf are preferably folded similar to the longitudinal side, as the side walls. In the parts of the shelf, however, the resulting channel is used as a rail for telescoping the two parts of the shelf. Of course, the dimensions of a first part of the shelf must of course be chosen slightly smaller than the dimensions of the second part of the shelf. Then the two parts are pushed into each other.

Preferably, the two telescopically movable parts of the shelf are screwed in any length. The second part of the shelf can be used e.g. have on its top surface and its side surface each offset from each other holes. The first part of the shelf may have mutually offset slots on its top surface and its side surface. Through the slots, it is possible, after the length of the shelf has been set to screw the two parts together and thereby stabilize.

The two parts of the shelf can be bolted together using the holes and the slots, in particular by the staggered slots and holes, the entire shelf length can be adjusted after the telescoping of the two parts of the shelf in any length. Thus, the two parts of the shelf can be assembled and stabilized in a predetermined by the distance of the two cabinets position.

For fixing the two parts of the shelf, simple angle plates serving on the side walls, e.g. be attached by a connector and on which the

Parts of the shelf, for example, be fixed by a screw.

In a particular embodiment of the side wall can be provided that spaced apart from the outside of the side wall, another sheet metal can be arranged with holes arranged like a matrix. The sheet may e.g. serve as a perforated wall, wherein in the holes fasteners for storing tools can be used.

In addition, it is provided that the metal sheet is coated prior to the production of sheet metal parts according to the invention. This type of coating is referred to as "coil coating" or "coil coating" and is described under the search term "coil coating" in the Internet encyclopedia "Wikipedia". The plastic can have any desired color. Thus, a designated outside to a designated inside of the cabinet may have a different color. The shelves can also differ from the color of the upper end part or the stand.

In addition, this coating has the advantage that the metal sheet can be easily folded without, for example, cracks in the applied (paint) layer form, which would require a costly reworking of the cabinet or shelf parts produced. The band coating reduces the manufacturing costs and leads by the coloring to an appealing design of the assembled cabinets or shelves.

FIG. 1 shows a cabinet 10 made from a modular system according to the invention, viewed from the front. The cabinet 10 comprises two side walls 12, between which an upper end part 14 is arranged as the upper end and a floor 16 is arranged as the lower end. Between the upper end part 14 and the floor 16 is a shelf 18 is arranged. Of course, several shelves 18 may be provided between the final part 14 and the floor 16. The final part 14 and the floor 16 are identical.

The side walls 12, the lid part 14, the bottom floor 16 and the shelf 18 are preferably made of sheet metal, in particular made of a steel sheet, wherein the sheet is preferably coated with color. In this case, all parts can have the same color; but it is also possible that at least the shelves 18 differ in color from the other parts.

Figures 2 and 3 show the side wall 12 according to the invention in detail. In this case, Figure 2a shows an outside view of

Side wall 12, while Figure 2b shows an interior view 22 and Figure 2c shows the side wall 12 as a section along the line A - A of Figure 2b show.

At the front edge of the side wall 12 a plurality of recesses 33 are present. In these recesses 33, for example, cage nuts (not shown) can be attached to which the hinges are screwed for cabinet doors. Of course, the function of the recesses 33 is not limited thereto.

As can be seen in particular from FIG. 2c, the side wall 12 consists of a metal sheet that has been bent outwards several times. The side wall 12 is made in one piece. At the front and the rear edge of the side wall 12, the metal sheet is preferably folded at right angles three times, so that forms on the outer side 20, a channel 24 having a substantially rectangular profile.

The two channels 24 stiffen the side wall 12. In addition, there are no sharp edges more. The free end 26 of the metal sheet does not completely close the channel 24, leaving a small gap between the free end 26 and the actual side surface 28 of the side wall 12. As a result, the production is further simplified.

At the top and at the bottom of the side wall 12, a tab 30 is folded outwards. The width of the tab 30 is substantially identical to the width of the channel 24.

Due to the inventive shape of the side walls 12, the inner side 22 of the side wall 12 is a smooth surface without interference edges.

The channels 24 of the side walls 12 have openings in the longitudinal direction (from top to bottom) in the vicinity of the front and rear edge. As can be seen from FIG. 3, a circular opening 32 and a rectangular recess 34 are preferably provided alternately along the channels 24. The openings 32, 34 serve to secure the lid part 14, the floor 16 and the shelves 18 on the side walls.

The cabinet 10 shown in FIG. 1 in a view from the front may comprise a rear wall (not shown). The rear wall can be screwed to the side walls 12, the cover part 14 and the floor 16.

If necessary, a door made of sheet metal can be arranged at the front of the cabinet 10 (not shown), so that the cabinet 10 can be closed.

The door can e.g. be attached via hinges arranged on a side wall. These hinges are fastened to the side wall 12 by means of the openings 32 or recesses 34.

FIG. 4 shows the side wall 12 in a perspective view of the outside 20 in a particular embodiment. On the outer side 20 of the side wall 12, spaced from the side surface 28, another sheet 36 is provided with a matrix-like opening. The sheet 36 is attached to the tab 30, e.g. with at least one screw connection. The sheet 36 may e.g. serve as a perforated wall, wherein in the holes fasteners for storing tools can be used. Of course, the sheet 36 may be attached to the outside wall without the apertures shown to form a visually attractive finish. Of course, it is also possible instead of a sheet 36 to attach a plate made of wood or plastic.

With the aid of Figures 5 and 6, the structure of the upper end part 14 and the floor 16 and their connection to the side walls 12 are explained in more detail by way of example. In the following description it is assumed that the lid 14 and the floor 16 are identical.

The components 14 and 16 are made of a rectangular sheet metal blank. The components 14, 16 have a cover surface 38, wherein the metal sheet is preferably bent at right angles to the narrow sides, so that form two panels 40 at right angles to the top surface 38 on both sides. To stiffen the panels 40 they are similar to the side walls 12 folded several times. The components 14, 16, 18 are thus bent substantially U-shaped.

In the figure 5a a variant is shown in which the top surface 38 is bent at its narrow sides in each case rectangular, so that mounting surfaces 42 arise. The visible in Figure 5a mounting surface 42 is partially cut free, so that the rear panel 40 is visible.

At the attachment surfaces 42 tabs 46 are formed, which serve to the floor 16, or mount the upper end part 14 in the recesses 34 of the side walls.

The rear of the two panels 40 may have holes or openings (not visible in Figure 5a), for example, to screw a rear wall.

In one embodiment of the components 14 and 16, both mounting surfaces 42 each have two holes, which together with the holes 32 in the channels 24 serve to screw the closure member 14 and the floor 16 with the side walls 12 can.

In an alternative embodiment of the components 14, 16, 18 according to FIG. 5 b, the attachment surfaces 42 have been created by folding the panels 40. In this variant, one of the mounting surfaces 42 protruding tab 46 is formed in each mounting surface 42. The tabs 46 can be inserted into the rectangular recesses 34 of the channels 24 according to the sequence shown in Figures 6a to 6c and hooked by depressing (see arrow 45 in Figure 6) of the components 14, 16, 18, so that also one Cabinet 10 according to FIG. 1 arises. Alternatively, a screw with holes 32 in the mounting surfaces 42 is possible (see Figure 5c).

The components 14, 16, 18 thus consist of a single metal sheet, which is completely manufactured by a purpose-specific blank only by targeted right-angled folding and targeted drilling or punching.

Figure 7 shows two adjacent and spaced-apart cabinets 10. Between the two cabinets 10, a shelf 47 is arranged in two levels. The shelf 47 comprises two telescopically displaceable parts 48, 48 ', wherein the first part 48' of the shelf 47 can be pushed into the second part 48 of the shelf 47. By the telescopically movable parts 48, 48 'of the shelf 47 can be achieved, that on the one hand, the distance between the two cabinets 10 can be used as a shelf wall. On the other hand, the cabinets 10 need not be placed at a fixed distance, namely in a length of prefabricated shelves, to each other. The shelf 47 can be fitted by the telescopically displaceable parts 48, 48 'in the desired length accordingly.

Figure 8 shows the two parts 48, 48 'of the shelf 47 in detail. The parts 48, 48 'are bent substantially in the same way as the side walls 12 at right angles to the longitudinal sides. The resulting channel is used here as a rail for telescoping the two parts 48, 48 'of the shelf 47. Of course, the dimensions of the first part 48 'of the shelf 47 must be slightly smaller than the dimensions of the second part 48.

For fixing the shelf 47 on the side walls 12 of the cabinets 10, an angle plate 50 is provided in each case, with which the two parts of the shelf 47 are screwed (see holes 52 in Figure 8). The angle plate 50 can be suspended in recesses 34 in the side wall 12, as has been explained in detail in Figure 6.

The portion 48 of the shelf 47 has on its top surface 54 and its side surface 56 each staggered holes 58. The portion 48 'of the shelf 47 has on its top surface 54' and its side surface 56 'each offset slots 60 on each other. The two parts 48, 48 'of the shelf 47 can be screwed together by means of the holes 58 and the slots 60, wherein by the telescoping of the two parts 48, 48' any length can be adjusted. Subsequently, the parts 48, 48 'by means of screws which are inserted into the slots 60, bolted. Thus, the two parts 48, 48 'of the shelf 47 can be stably assembled in a predetermined by the distance of the two cabinets 10 position.

Each part of the shelf 47 thus consists of a single metal sheet, which is completely manufactured by a specific intended blank only by right-angled folding and targeted drilling or punching.

A non-telescoping shelf consists of a part 48 in the desired position, which has a (mounting) bore 58 at both ends.
