Rensch, Lerchesbergring 2kt 6 Frankfurt am Main,

The present invention relates to a building kit for the manufacture of furniture, consisting of building components which determine the appearance of the furniture, along the side edges of which a base profile is provided, comprising a tie part, a strip beveled at its longitudinal edges and a web connecting the tie part and the strip and thus forming two grooves on which the web acts as an integral groove base, and a connecting piece for connecting adjacent building parts by gripping the base profile grooves.

Such furniture can be chairs, tables, office desks, cabinets, office cabinets, shelves, exhibition boards and many others. In the past, furniture has been assembled from rods, plates, brackets, and other elements joined together by screwing, gluing, tapping, and crimping, using hinges, ligaments, and many other aids. Especially for heavy furniture used in offices, workshops and clothing shelters, the plate-like elements are made in such a way that the frame or frame is assembled from the profile strips, usually by welding, and the open areas are closed with any sheet material, sheet metal, hardboard or hardboard. In this case, little value is placed on the aesthetic effect. Naturally, the aim is usually to pre-form furniture items for disassembly and assembly so that they can be stored and transported economically. In this case, the aesthetic effects must also be avoided, the ends of the screws are visible to the outside, longitudinal slots are formed in the rods to fasten the support members to them with hooks, on the support members of which the plate elements are located. In addition, economic considerations must also give way to the quality of the furniture to be dismantled due to the rest of the system.

The object of the present invention is to provide all kinds of pleasant-looking furniture and individual parts from which the furniture is assembled, always using the same basic elements which ultimately provide a pleasant appearance, with economic production and simple and convenient installation and disassembly being paramount.

Thus, the invention is mainly characterized in that all the side edge surfaces of the plate are provided with a base profile and possibly provided in a manner known per se along all their surfaces with rails with a base profile and along the base profile binding part and the strip are chamfered to each common plane intersecting the base profile symmetry.

Preferably, to connect adjacent plates or rails and plates, pairs of connectors are provided which force-lock the pairs of grooves of the basic profiles to be connected, which have common bases. Each connector has a pair of parallel grooves for gripping the base profile strips of the two components to be connected and that a pair of connectors with a screw or similar in the central bore holds both components together.

Angle pieces that can be inserted into adjacent grooves in the basic profiles of the interconnected plates can be used as the connecting piece for the angle-related plates.

According to a preferred embodiment, the construction set consists exclusively of a plate and corner joints connected in three planes, which can be inserted into corner grooves between the opposing connecting parts and strips of the basic profiles.

According to the invention, brackets are arranged as connectors between the rails and the plates, which engage loosely from below in the downwardly open grooves of the basic profiles of the plates arranged horizontally. The brackets have a substantially L- or T-shaped cross-section and edges rising up along at least one edge of the T-shaped cross-section, which from below engage in a groove formed in the base profile of the plate by its binding part, strip and web.

Preferably, a vertical notch is provided in the web end of the L- or T-shaped brackets, by means of which the web is placed on the web of the basic profile of the vertical rail.

A preferred embodiment according to the invention comprises a skirting board with a U-profile and flanges with aligned vertical notches into which the webs of the basic profiles of the support rail can be inserted.

Some application examples of the invention are shown in the drawings in which:

From the cross-section of the extruded base profile 1 it can be seen that it is formed by a wide binding part 2, a narrower strip 3 and a web 4 connecting the binding part 2 and the strip 3. The binding part 2, strip 3 and web 4 form two channels 5 opening in opposite directions and having bottoms 6. Planar chamfers are cut at the edges 8 of the binding part 2 and the strip 3 of the base profile, which are at an angle to the central plane of the base profile.

This basic profile 1 is also shown in the other basic profiles according to Figures 2, 3.

Protruding perpendicularly from the edges 8 of the base profile binding part 2 according to Figure 2 are flanges 16 with second flanges 60639 17 at an inward angle, which act as anchoring flanges and which will be explained in more detail.

On the opposite side of the strip 3, the bonding part of the basic profile 1a supports two connection strips 9, which together form a channel 10. The edges of the connection strips 9 are at an angle t to the connection strips themselves and support outwardly extending corner sections 12. These connection strips can also be considered as anchoring strips. explained in more detail below.

Also, Fig. 4 shows an extruded basic profile in the form of a rectangular tube 7 used as a rod. The four side walls of the tube 7 are again formed by basic profiles 1 which are connected to each other at the edges 8 of their connecting parts 2. Figure 4a shows a triangular tube formed by similar basic profiles.

According to Fig. 5, a frame or frame of plate elements is made of the base profiles 1 by cutting the adjacent ends of the base elements 1 into chamfers 18, after which a connecting plate 14 shown in Figs. 9 and 9a is connected to the channels 10 at the chamfers 13. Both surfaces of the plate 14 are grooved with saw blade teeth. The plate 14 is inserted into the base profile 1 so that the channels 10 at the chamfers 18 become completely filled with the plate 14, as can be seen in Figure 6. The co-operation takes place in the direction of the arrows in Figure 5.

A frame made of basic profiles according to Fig. 2 is shown as an application example in Figs. 7 and 8. Also in this case, the ends of the basic profile 1 are cut into chamfers.18. Now the branches of the connecting corner piece 19a are pushed into the space between the flanges 16, 17 and the binding part 2 on the beveled ends and the basic profile t1 is pushed into one of the positions shown in Fig. 7 as the frame angle according to Fig. 8. This connecting piece is also provided with sawtooth-shaped teeth on the outer surfaces of its branches.

According to Fig. 9, the connecting plate 14 has a saw blade tooth with teeth 20 extending perpendicularly and transversely to the section line A-B running along the edge of the chamfers 18 of the frame.

Figure 9a shows a larger section along the line A-B. The teeth are marked with reference number 20 and their tips with reference number 21.

Fig. 11 shows a table formed by four rods 7, four brackets 28 and one table top 23, the edges of which are lined with basic profiles 1. When assembling the table, the brackets shown in Figs. 12, 13 and 14 can be used. 24 and a vertical rim 25 and a horizontal flange 26. A gap 27 is machined from below in the vicinity of the ends of the web 24. By means of this gap 27 the supports 28 are suspended in the web 4 of the basic profile 1 of the tubular rod St of Fig. 4.

On top of these supports 28 a table top 23 is arranged, the edges of which are provided with basic profiles 1. When the table top is lowered onto a four-bar St and four supports 28, it rests on its lower surface on the upper surface of the horizontal flanges 26 of the supports 28 and is held in place by the vertical profile 1 on channel 5.

The supports 22 according to Fig. 12 are also made in a similar manner. They also have a web 24 with slots 27, a horizontal flange 26 and a vertical rim 25.

Fig. 14 shows a table base with its support 28 and rods St. The web 4 of the basic profile 1, the upper surface of the strip 3 of which is visible from above, is shown in dotted lines. The second broken lines show the gap 27 to which the web 4 of the rod St adheres.

Fig. 15 shows a wall shelf provided with supports according to Fig. 18. In addition to the supports, the shelf comprises wall rails 30, spacers 31 and plate elements 32. The wall rails 30 are fixed at a distance from each other to the wall (not shown) determined by the length of the plate elements 32 in a manner known per se. All other parts are plugged into the wall rails and to each other. According to Fig. 16, the wall rail has a rear surface 35, two side surfaces 36 and a front surface 37, whereby a dovetail groove 38i is formed in front of the rear surface. The wall rails can be made of plastic or metal by extrusion.

According to Fig. 17, the spacer body 31 is an extruded profile body with a cross-section in the shape of a box profile. A dovetail portion 40 is formed on the rear side 39, which is connected to the dovetail groove 38 of the wall rail 30. The box profile of the spacer 31 is formed by a rear wall 39, two side walls 41 and a front wall 42. The back wall 39 and 60639 have grooves 43 along the center of the inner side 42.

According to Fig. 18, the support 33 is T-shaped in cross section. T has a back portion 26 and a web 24 in which a slot 27 separates the guide body 47. The free edges of the flange 26 have vertical edges 25 with edges formed in the edges 50. The support 24 is made by extrusion and a slot 27 is sawn or milled therein.

Fig. 19 shows a part of the wall rail 30, a spacer 31 and a support before they are fitted. After matching, a shelf rack according to Fig. 20 is obtained. The bracket 33 is retained between two spacers 31 slidably connected to the dovetail portion 40 in the dovetail groove 38 of the wall rail 30. A.

As shown in Fig. 21, there is enough space to insert the plate element 32 over each vertical rim 25 or the other rim 25 whose lower channel 5 between the edge profile (not shown) of the plate element edge and the strip 3 'engages the rim 25 and will rest from the thickening 50. against. The rear surface 35 and the front surface 37 of the wall rail 30 and the rear wall 39 and the front wall 42 of the spacer 31 have the same width. Since the distance A between the edges of the support 33 is wide enough to freely receive the base profile strip 3 of the plate element 32, the plate element can expand from the front edge of the support to the wall. The plate element 32 has a frame formed by basic profiles, which, as will be explained in more detail below, is foamed with a foam material and which is coated at least on its upper surface with a film 34 of metal, plastic, fabric or the like.

As can be seen from Fig. 21, the same * as shown in perspective in Fig. 20 is shown in partial section in Fig. 21 to clarify how the plate element 32 is fitted on the support 31. In this case, it is noted that the lower and upper spacers

1 I

9 60639 13 31 rests on the flange 26 of the T-profile of the bracket 33. However, it does not appear that the guide piece 44, 47 separated from the groove 24 by the slot 27 is inserted into the box-like profile of the lower spacer.

The basic profile 1. of the frame surrounding each plate element is shown in section. The channel 5 between the bonding part 2 of the base profile 1 and the strip 3 adheres to the edge 25 of the flange 26 of the support 33. In this case, the distance S between the base profile strip 3 and the side wall 41 of the spacer 31 is maintained. In addition, the distance A between the thickeners 50 is kept sufficiently large.

The connection between the wall rail 30 and the spacers 31 via dovetail guides 38, 40 and the connection between the spacer 31 and the support 33 with the guide 47 in the groove 43 gives a completely rigid frame to the shelf to which the plate elements 32 can be connected in the simplest possible way.

Figure 22 shows an exhibition shelf. It comprises two rods or bars St formed by the tube 7 according to Fig. 4, which support horizontal plate elements 32 and vertical plate elements 32 by means of supports 22 or 28. The rods St are provided with baseboards 53 which provide a stable standing support for the exhibition stand. The baseboards 53 (Fig. 23) are U-shaped in cross section and have flanges 54 and a back portion 55 to which adjusting screws 56 are threaded to adjust the stability of the display stand.

Fig. 24 shows the possibility of displaying a display stand or other shelf on both sides of the plate element P with a glass plate or some other plate 57. In addition, clamps 65 and 66 are used, which will be explained in more detail below. A strip 61 of plastic or other suitable material is fitted in the groove 76 of the clamp 66 and in the groove 77 of the clamp 65, which is pressed against the non-slip strips 64 in the channels 5 of the base profile 1 around the plate element P. Fig. 25 shows another embodiment of the clamp 65a, 66a, in which the strips 61 have been replaced by a cam 67.

According to Fig. 26, two plate elements, of which only two basic elements 1 according to Fig. 2 are shown, are connected to each other. In addition to these, two connecting clamps 69 are used, which, after clamping, are located on their backs 71 at the level of the surface of the plate elements. the body pieces are U-shaped in cross-section, with two flanges 70, a back portion 71 and two vertical lugs 72 and 73 projecting internally from the back portion of the U-profile relative to the flanges 70. The lugs 72 and 73 have toothing 22a, 23a which project in the same direction, through these teeth, the core clamps are pinched in contact with other parts. The distance between the flanges 70 of the lugs 72 and 73 is different and dimensioned so that the flat back of the lug 73 after tightening is pressed tightly against the surface of the base profile 1 of the two profile members 1 to be clamped by the elastic force of the connecting clamps 69. The flanges 70 extend into the channels 5 of the base profiles, in which the anti-slip strips 64 are arranged. Fig. 27 shows how in this way the rod St is connected to the two vertical plate elements P Ckts. also 26). The rod is formed by the tube 7 according to Fig. 4, in which the basic profile 1, with its binding parts 2, the strips 3, the web 4 and the channel 5 is repeated four times. The clamping takes place in the same way as just described above in connection with Fig. 26 with respect to the two plate elements.

According to Fig. 28, the shelf has a vertical plate element P, from which only the basic profile can be seen. In addition, two supports 28 are shown, by means of which two connecting pins 65, 66 are fastened as in Fig. 25. Instead of the basic profile p of Fig. 24, the basic profile of the plate element P is used according to Fig. 28 and the guide strip 47 of Figs.

An alternative to clamping according to Figures 26, 27 and 28 is shown in Figures 26a and 26b. Reference numeral 94 denotes two clamps of a pair of pins through which a screw (not shown) is fitted in the bores 96 passing through it.

Each clamp 94 has two parallel slots 95 into which the strips 3 of the basic profile 1 of the two plate elements to be joined are inserted on both sides. A screw (not shown) fitted in the bore 96 provides a fixed connection of the plates P via the clamps 94.

With similar pairs of pins 94, the rods St and the plates shown in Fig. 27 can also be fastened to each other.

11 60639

Figures 29 and 30 show a hinge 87 comprising a hinge pin 88 and a cross-section of the hinge half 89 with its bases 90 and a bore for the hinge pin. With the surface of the bases 90, the hinge halves 89 are arbitrarily fastened to rest against the back of the strips 3 of the edge profiles of the plates P.

According to Fig. 31, a shelf unit is assembled from the four plate elements P and the two connecting corner pieces 19 according to Fig. 10.

According to Figure 10, the outer surfaces of the branches of the connecting corner piece 19 have a saw blade toothing 20, the tips 21 of which run transversely to the main axis of the branches.

The finished shelf unit is shown in Fig. 32. Fig. 33 shows a shelf assembled from the shelf units of Fig. 32. Also, several such private shelf units can be stacked on top of each other. Using the plate elements P and the connecting corner pieces 19, in addition to the shelf shown in Fig. 33, a cabinet, desk or some other piece of furniture and space dividers with compartments or cabinets can also be assembled into a rigid whole, which can be continuously in the same shape.

Fig. 34 shows the junction of four plate elements P1, P2, P3, P4, which plate elements contact each other with the basic profiles of their edging. A rigid connection is achieved by connecting the connecting corner pieces 19 to the channels 5 of the basic profiles. The basic profile used here has already been explained in connection with Fig. 2. A pair of pin strips 9 protrude from the bonding part 2 of the basic profile. The area of the plate element P is foamed with poly-styrene. The flotation adheres to the groove 10 between the coating strips 9 and in particular to the corner 12 of their edges. A film 34 is arranged as a coating on each surface of the flotation 15.

The design of one corner of a similar piece of furniture is shown in Fig. 35. The two plate elements are placed at right angles to each other, whereby the edges of the binding parts 2 and the strips 3 of the basic profiles 1 at the edge of the basic profiles are opposite. The fixed connection between the two plate elements P is achieved by striking the connecting corner pieces 9 at the open ends of the rectangularly facing channels 5 between the connecting parts 2 and the strips 3. For safety reasons, the holding nail 95 can also be punched through the connecting corner piece 19 and the binding part 2 in the channel 5 of the strip 3 of the basic profile 1.
