ASSOCIATION OF STEEL FURNITURE

The invention relates to the connection of a steel furniture structure in a furniture structure in which the ends of beams formed by edging a steel plate can be connected and detached to other ends of beams formed by edging a steel plate substantially perpendicularly and without separate locking parts.

According to the known method, the steel shelf structures are assembled from parts which are, for example, vertical ends, i.e. ladder parts, and horizontal shelf levels. In the manufacture of ladder parts 10, for example, welding, riveting or screws are used in the joints. Screws or some kind of hook construction are usually used to assemble the shelf. It is generally desired that the shelf also be modifiable and expandable as needed, so that the assembly of the shelf should be as simple as possible without fixed joints such as welded joints.

Especially when it is desired that the shelf be easily disassembled and assembled for short-term events, such as exhibitions, etc., the joints 20 must first be easy to open. Disassembly and assembly work must also take place quickly and preferably even without tools. In this case, it is advantageous if the shelf can be quickly dismantled into suitably small and easily transportable parts, whereby space savings can be as much as 90%.

25 In this way, e.g. freight costs save considerably.

The object of the present invention is to provide a new method of joining steel structures for the above purpose, which enables the rapid assembly and disassembly of parts without tools.

The invention is characterized in that - grooves perpendicular to the beam are formed on both sides of the first beam formed by edging the steel plate, that in the joint the second beam is pushed into place in the direction of the grooves of the first beam so that the C-profile trough of the second beam surrounds the end of the first beam and the edge flanges of the second beam lock into the grooves of the first beam.

By means of the invention, steel structures made of sheet metal can be quickly connected to each other without tools. Disassembly is just as simple.

Other features of the invention are set out in the following claims.

The invention will now be described by way of example with reference to the accompanying drawings, in which

Figure 1 shows a vertical support of a steel shelf implemented by a joining method according to the invention.

Fig. 2 shows the lower part of the vertical support of the steel shelf of Fig. 1 disassembled.

Figure 3 shows a section taken along the line III-III in Figure 1.

Figure 4 shows 25 sections taken along the line IV-IV in Figure 1.

Fig. 5 corresponds to Fig. 4 and shows another embodiment of the horizontal bar.

Fig. 6 also corresponds to Fig. 4 and shows a third embodiment of the horizontal bar.

Figure 1 shows a vertical support 10 for a steel shelf implemented by a joining method according to the invention. The vertical support is formed by two vertical columns 11 and 12 and two horizontal beams 13 and 14. Both the vertical columns and the horizontal beams 3 86573 are similar in this embodiment.

Fig. 2 shows the lower part of the vertical support 10 of the steel shelf of Fig. 1 disassembled, whereby the connection method of the parts is also clear from the figure. In Figure 2, both the horizontal beam 14 and the vertical columns 5 and 12 are formed of a bevelled steel plate.

Grooves 15 and 16 are formed at both ends of the horizontal beam, to which the edge flanges 17 and 18 of the vertical columns 11 and 12 fit. The vertical columns 11 and 12 are connected to the horizontal beam 14 so that they are pressed into place in Fig. 2 from the top 10 downwards. The edge flanges 17 and 18 of the vertical column 11 then advance in the guides formed by the grooves 15 and 16 until the lower end 19 of the vertical column 11 meets the bottom plane 20 of the horizontal bar. In the joint, the vertical column rests against this plane.

Such a structure also has the advantage that the lower surface of the vertical support 10 resting against the floor 15 is level 20. Thus, the lower surface of the shelf is flat, so that no separate floor-facing washers need to be added under the shelf, as in known structures.

Fig. 3 is a section taken along the line III-III 20 in Fig. 1, showing the end of the horizontal beam 14 and the vertical column 11 in section from above. It can be seen from the figure that the vertical column 11 as if surrounds the end of the horizontal beam 14. The edge flanges 17 and 18 of the vertical column 11 are arranged in grooves 15 and 16 formed in the horizontal beam, which are directed slightly 25 obliquely towards the free end of the beam. The edge flanges 17 and 18, together with the obliquely oriented grooves 15 and 16, form a locking that holds the structure in place. To the left of the vertical column 11 there is shown the bottom plane 20 of the horizontal beam 14, in which a narrow projection is formed, against which the vertical column 11 is pressed in the connection situation.

Fig. 4 is a section taken along the line IV-IV in Fig. 1, showing the lower end of the vertical column 12 and the horizontal beam 14 in partial section. It can be seen from the figure that the horizontal beam 14 is edged from a steel plate to form a beam - 4 86573 racket with ten edges 22 with two opposite troughs. Vertical grooves 15 and 16 are formed on both sides of the beam, into which the edge flanges 17 and 18 of the vertical column 12 are fitted. In Fig. 4, the upper surface 21 of the beam between the grooves 15 and 16 5 and other parts marked with a shear line form an intact part of the beam 14, i.e. the load-bearing structure.

Fig. 5 corresponds to Fig. 4 in other respects, but shows another embodiment of the horizontal bar 14. Such a method of edging the horizontal beam 10 10 has sought to reduce the number of work steps required. The horizontal bar of the figure has nine edges 22.

Correspondingly, in Fig. 6, the number of edges 22 of the horizontal beam 14 is further reduced. The number of edges 22 has been reduced to five by using oblique surfaces 23 in the structure different from the main plane of the beam 14.

The upper plane 21 and the lower plane 20 of the beam are still parallel to the horizontal plane.

It will be apparent to those skilled in the art that various embodiments of the invention, as well as the shape and appearance of the structures, may vary within the scope of the claims set forth below.
