A furniture-type furnishing article, in which at least one outer wall is formed by a frame and at least one wall part held therein, the latter being held along its edge at the inner periphery of the frame at the periphery of the frame struts which are in particular tubular, the edge of the wall part having a recess and the wall part embracing along its edge a partial area of the frame struts essentially in a form-locking manner, characterized in that the wall part (22; 80; 104) is composed of at least two plate members (24, 26; 32, 34; 40, 42, 44, 48, 50, 52; 54, 56; 62, 64, 66; 76, 78; 76, 86, 78; 108, 110), which are disposed adjacent each other and are formed differently, and in that the edge regions, facing one another, of the plate members, rigidly connected to one another, form between themselves a recess (e.g. 58).

Description

The invention relates to a piece of furniture in which at least one outer wall is formed by a frame and at least one wall part held therein, the latter being held along its edge on the inner circumference of the frame on the circumference of the tubular frame spars in particular, and the edge of the wall part has a recess and the wall part encompasses a partial region of the frame bars essentially in a form-fitting manner along its edge.

From US-A-2 806 755 a cabinet of the type mentioned above is already known, which has a frame composed of tubular pieces, which forms several frames, in each of which a wall part in the form of a solid plate is inserted. So that the plates are held in the frame, they are provided on the circumference with a groove-like recess which is circular in cross-section and into which the tubular frame spars engage.

If devices are to be housed in the known cabinet in a silenced manner, it is necessary to apply sound-absorbing or sound-absorbing layers to the inside of the plates. If it is intended to insert or mount intermediate shelves, holes must be drilled from the inside into the plates for the fastening screws of support strips or the like, or grooves must be milled for inserting support strips. The outside of the board, on the other hand, must be veneered or coated with plastic to give the furniture a good appearance. There are also many other cases in which the inside of the plates have to be processed differently than the outside of the plates.

By means of the present invention, this known furniture-like piece of furniture is to be improved in such a way that the two sides (outside and inside) of a wall part of such a piece of furniture can perform different technical functions without reworking and without great effort, so that it can e.g. it is possible to attach support elements for intermediate floors or guide elements for drawers in the interior of the furniture, or to design the interior of the furniture to be sound-absorbing, without the appearance of the piece of furniture being adversely affected thereby. Starting from a piece of furniture of the type mentioned at the outset, this object can be achieved according to the invention in that the wall part is composed of at least two plate bodies which are arranged next to one another and have different designs and that the mutually facing edge regions of the fixedly connected plate bodies form the recess between them. The invention not only achieves the stated object, but also makes it possible to produce parts of furnishings in a modular system, so that e.g. Large numbers of panel bodies with a specific decor that will later form the outside of the wall parts can be produced, even if the inside of the different wall parts have different functions; a wall part can also be retrofitted to another function at any time e.g. convert its inside.

From DE-A-1 928 840 it is known per se for roofs, ceilings, walls and similar elements from the building industry to form frames from pipes and to hold them in this wall part, which are composed of two identically shaped plate bodies and thereby in the frame are held in such a way that the plate bodies are bevelled on their circumference in such a way that two plate bodies together form a concave cross-section on the circumference of the wall part you have formed, into which the frame bars engage in a form-fitting manner. However, due to the different technical subject area and the fact that the prior art provides wall parts made of identically designed plate bodies, these known structural elements were unable to suggest the invention.

So that there is no noteworthy groove, notch or the like between the wall part and the frame spars holding it, at least on the outside of the furnishing, it is advisable to bevel or graduate at least one of the plate bodies to form the recess in its edge area facing the other plate body.

If the wall parts are heavily loaded and only held on the frame bars as a result of bevels of the plate bodies, there could be a risk of the edge regions of the plate bodies weakened by the beveling breaking away. An extraordinarily resilient connection between the frame bars and the wall part is obtained, however, if at least part of the frame bars has a longitudinal web on the circumference for engagement in a recess formed by the two plate bodies.

In order to save wood, plastic or other expensive materials or to achieve special properties such as high sound absorption of the wall parts, it may be advisable to form the panel body from at least two cover panels, between which a filling, e.g. made of foam plastic, is inserted becomes. The filling can also form a core that is resistant to machining with tools or heat, which creates safety furniture. If high sound absorption is important, it is advisable to use at least one of the Perforate cover plates and use a sound absorbing filling.

The two plate bodies can e.g. by screws, nails or the like introduced from the inside of the wall part in question. For certain applications, however, it is advisable to connect the plate bodies to one another by means of a solidifying compound introduced between them, so that a full-surface connection is created. Safety furniture can also be created in a simple manner if a filler made of heat-resistant and impact-resistant material is used. If the filling compound is used to connect the two plate bodies, it is particularly advisable to attach anchoring elements to the inside of the plate bodies, which are then embedded in the filling compound.

In a particularly preferred embodiment of the item of furniture according to the invention, at least some of the frame bars have openings or a longitudinal slot on their peripheral part enclosed by the wall part and they are poured out with the filling compound. This enables two things to be achieved: on the one hand, the filling compound can serve to firmly connect the frame spars that form a frame, and if a filling compound that is resistant to machining by tools and / or heat is used, this can also be avoided Interior of a piece of furniture, for example can be penetrated by drilling through the frame spars, or that the insulation of the interior in the area of the frame spars is not provided in a fire-proof cabinet or the like.

The invention is to be explained in more detail below with the aid of some preferred embodiments shown in the drawing.

• Fig. 10 is a perspective view of a corner portion of a cabinet housing designed according to the invention.

Fig. 1 shows a wall element of a piece of furniture, which has a e.g. has closed frame, which is made by a center tube. This frame is, for example, rectangular and forms quarter-circle arcs in its corner area. At 22, a plate is designated as a whole, which is fixed in the frame. For this purpose, it has a plate body 24 that completely fills the frame and which partially engages around the inner peripheral part of the frame 20 in a form-fitting manner. To hold the plate body 24, strip-like plate bodies 26 are used, which enclose the frame 20 to form the plate body 24 symmetrically and are screwed onto the inside of the plate body by means of fastening screws 28. In this way, a mutual firm connection between the frame and the plate is achieved without the need for fastening means for this purpose. Instead of circumferential strip-like plate bodies 26, such can also be provided only in regions on the plate body 24. The thickness of the two plate bodies 24, 26 is preferably chosen such that the thickness of the plate essentially corresponds to the diameter of the hollow cylindrical tube 30 forming the frame, so that there are no projections relative to the frame. However, the construction can also be made according to FIG. 1 a. In this case, the plate bodies 24, 26 partially overlap the frame bars with an edge piece. Depending on the type of furnishing the converting element is to form part of, the pipe 30 can also be used for the installation of electrical and / or sanitary lines.

If, for example, the wall element forms part of a desk, telephone lines and electrical connection cables for office machines can be laid in the pipe.

In the exemplary embodiment according to FIG. 2, the plate 22 held in the frame 20 is formed, for example, by two uniform plate bodies 32 and 34, which are still covered on their outer surfaces with a covering layer 36 and 38, respectively. With this construction, it is clear from the structure of the plate 22 that the invention achieves a functionally configurable wall element, for example in that the outer plate body 32 can be designed differently and can therefore be assigned different functions and have different properties than the inner plate body 34. This becomes based on the embodiment of FIG. 3 more understandable. There is, for example, a sandwich-shaped plate 22 composed of two differently shaped plate bodies, the upper plate body having, for example, a core 40 and two cover plates 42, 44 attached to it, which can be laminated on, for example, and of which the cover plate 42 is still equipped with openings 46, while the other plate body, for example Core 48 formed from cardboard, which is also covered on both sides by cover plates 50, 52.

In contrast to the constructions described above, these two plate bodies are preferably through with one another over the entire surfaces of the cover plates 44, 50 Adhesive connected, whereby · the mounting of the plates in the frame 20 is achieved. Instead of gluing, the connection can also be accomplished by means of fastening elements such as screws, clips, rivets, etc.

The construction described forms, for example, a wall element with the ability to have particularly good sound absorption. Instead of the core 40, 48, the plate bodies can also be hollow and perforated on at least one outside, for example for the purpose of ventilation or for supplying a fluid. If such plate bodies are used for the construction of safes, for example water pipes can be installed in the plate body in order to cool the contents of the safe in the event of a fire.

The construction according to Figure 4 illustrates a variant of the mounting of a plate 22 in the frame 20, namely that the two form e.g. massive plate body 54, 56 has a circumferential groove 58 which is V-shaped in cross section.

The exemplary embodiment according to FIG. 5 is, for example, a wall element of a security housing, for example the armored door of a locker. In this embodiment, the plate 22 is equipped with a core 60 made of highly heat-resistant and impact-resistant material, which e.g. is drill-resistant on one inner side with a cover plate 62 and on its other outer side through two cover plates 64, 66. The cover plates are held on the core by means of fastening elements 68 which are cast into the core. In this embodiment, the wall thickness of the tube 30 of the frame 20 is also reinforced accordingly. It is clear that the arrangement of the cover plates can also be reversed.

Figure 6 shows a similar embodiment of a wall element, which is suitable for armored cabinets, for example. The difference from the construction described above is that in this case the tube 30 has openings 69 on its peripheral part enclosed by the plate 22, and that the core 60 also extends into the openings of the tube.

In the wall element according to FIG. 7, the frame is designated 70, and is produced by a hollow profile which is, for example, semicircular in cross section and has a flat base 72 on the inner periphery of the frame, on which a web 74 extending in the longitudinal direction of the profile is formed. The two plate bodies of the plate 80, designated 76 and 78, hold the web between them, which likewise results in the mutual connection of the frame and the plates.

The embodiment according to Fig. 8 differs from the above in that the longitudinal web 74 is the web of e.g. Forms T-shaped metal profile 82, which is inserted into a guide groove 84 formed in the base 72. In both constructions, the plate body 78 is stepped accordingly to accommodate the longitudinal web 74. The spars of the frame 70 can be made of suitable plastic or rubber, so that the frame can also be deformed to a certain extent, thereby reducing the risk of accidents in the event of an impact. As illustrated in FIG. 8, partition walls on the outside can also be covered, for example, with a cover film 86, which can represent, for example, an imitation leather.

FIG. 9 illustrates a solid frame spar 88 which is convexly curved in the region of its one longitudinal edge at 90, seen in cross section.

It has two longitudinal sides 92, 94 lying at right angles to one another, into each of which a receiving groove 96, 98 is incorporated, which each serve to receive a T-shaped fastening profile 100, the webs 102 of which for holding plates 104 which are assigned to one another vertically on the frame , 106 serve, which in turn, for example are formed from two plate bodies 108, 110. The frame spar 88 can be extruded from plastic, for example.

Finally, FIG. 10 illustrates the corner part of a furniture housing which is formed by a plurality of frames or frame parts 112, 114 welded to one another.

It can be seen here that the frame 112 is formed by a one-piece tube 116 bent at right angles, which is shaped in the form of a quarter-circle arc in the corner region of the frame. On this quarter-circle arc a spar 118 of the frame part 114 is welded perpendicular to the plane of the frame 112 such that the corner part shown is completely rounded and the edge defined by the spar 118, as well as the two other edges defined by the tube 116, are rounded . Plates 120, 122, 124 are inserted in the individual interconnected frames in the manner described above.

In a cabinet housing produced in this way, all housing edges can be rounded off in a technically simple manner in the sense of a softline design, the plates being able to be designed in such a way that they pass practically seamlessly into the scope of the frame spars. The outside of the plates can be designed according to individual wishes, for example by laminating appropriate foils or covering with leather-like cover material, while on the inside they can have a completely different, functional design. For example, the inner plate body of the plates can be equipped with rows of holes in order to be able to hang up rails or similar internals. It is clear that the inventor Dung allows multiple constructive modifications without the construction forms found out of the scope of the invention.

As already indicated above, the invention also makes an important contribution to construction technology. For example, wall and ceiling elements can be produced which, e.g. due to an at least partially hollow design of the plate body, allow indirect, draft-free room ventilation. The frame spars can consist of a wide variety of materials, and in the case of hollow spars, the interior thereof can be used, for example, for installation purposes.
