Attached to quick-install benches or seat holders, especially for auditoriums. - Faste på snabbmonterbara sittbånkar eller sittstod, i synnerhet av tribuner.

The invention relates to a bracket for quick-to-install benches or seat holders, in particular for auditoriums, in which case the benches or seat holders can be placed on the horizontal bases of the bench holders and fastened by means of a plug connection and in which the overlapping parts the arms and the bench-sS or the seat holders have, at their ends, bench openings (gap, gap) adapted to the dimensions of the flat part, preferably in each case a gap, and a connecting part extending across the gap.

In auditoriums or other equipment with benches or fasteners for seats, such as cubic seats, long parts are usually supported at the ends. In order to prevent them from rising from the lower frames, in particular from the stands of the stands, so that other users fall to the ground when they are used by the user, they must be fitted with suitable supports and joints which, however, must be able to be installed and put in place quickly. on the other hand, it must be possible to dismantle very quickly. Until now, such connections have generally been made with screws and nuts (DE-GM 1 973 139, Fig. 8 and pages 6/7; US-PS 2,611,422, Fig. 13).

In an embodiment according to DE-OS 35 19 718, the benches are punctured separately from the holders and are secured to the sides by displacement with pins. An embodiment according to GB-PS 898 121 has an upwardly rising connecting plate, in the hole of which the hook part attached to the next bench can be hung. This requires each bench to be raised in a fastener without a hook and the hook portion to be inserted at the other end into the hole in the connecting plate of the next bench. This requires a great deal of installation effort, usually for two people.

The hook part is also embarrassing in the seat.

The Office for Patent of the Federal Republic of Germany submitted the technological background to the application only in the following documents, which are already mentioned in part.

DE 85 33 418 U1, DE 82 32 782 U1, DE 78 1 0 046 U1, DE 70 03 435 U1, DE 1 9 82 570 U1 and DE 1 9 29 665 show a wide variety of seating furniture with horizontal slats attached to the base with a variety of connecting and screwing methods, which, however, have nothing to do with the particular structure according to the invention.

DE 19 73 138 There is an error in the designation of U1, since the text deals with a height-adjustable trolley for tiled floor installers and similar professions, the construction of which has nothing in common with the invention.

U.S. Pat. No. 2,611,422 discloses a spectator apparatus in which truss girders with the same pitch have vertical, upwardly open tubes into which flange parts are inserted, the sleeves of which are secured at the sides by tightening screws passed through them and on the benches of which benches are screwed. The use of screws requires considerable installation effort and cannot be compared to the fastening system according to the invention.

DE 35 19 718 A1 and GB 898 121 = DE-OS 14 09 400 have already been discussed above.

At the time of filing the Priority Application for the invention, non-public DE application 3909964 (= FI 901514) discloses holding loops extending upwards towards the seat holders in order to secure the benches. At the ends of the seats, there is a flat iron with holes connecting their parts, which is fitted on top of the pins. The ends of the two adjacent seat benches are side-by-side. There is a loop between them. In each case of the loop opening 3 91657, a wedge is pushed in which the flat irons of the benches to be joined are firmly attached to the rise. Installation can only take place from below.

It is an object of the invention to provide a quick-to-install and disassemble-like, simple connection between bench holders and bench or seat holders.

This object is solved in this way, and the fastener according to the invention is characterized in that the flat parts are formed as holes, which are arranged from above through the bench openings (slit, valley) and pushed in each case through an opening in the bench base. a wedge which extends through the wedge hole of the hole plate acting as a securing opening and in which case the hole plates are provided with supports at the edges provided with the connecting parts of the bench openings.

By using only one perforated plate, which is fitted in a deliberate manner and the hole of which is inserted into the wedge, a connection can be quickly and securely installed which is difficult for the average user, let alone a child, to loosen due to the wedge. people are not in danger. The connection is strong in the installed position and can be easily removed for disassembly. There are several performance options depending on where the hole plate is to be attached and / or supported.

In a preferred embodiment of the invention, the perforated plate consists of a flat part with a rectangular wedge hole, which is welded or molded at an angle of 90 ° to the flat part acting as a support for the perforated plate.

In another preferred embodiment of the invention, the benches consist of two boards or other seat parts attached to the joints 4 91657 spaced apart, for example of reinforced plastic or light metal profile, which are baked connected to the joints so that the gap between the slots corresponds to the gap. and the bases have openings for the passage of the perforated plates.

In one preferred embodiment, in the middle of the support surfaces of the benches of the benches are the abutments of the perforated plates, on which the connecting parts of the benches or the like rest in the longitudinal direction, supporting the benches and leaving a gap on the perforated plates.

A preferred embodiment of the invention is described in the following description with the aid of other drawings, advantages and angles of view of the invention.

The fastener 130 of the quick-install benches 131 has, for example, benches 131 consisting of two separate boards 132.1 and 132.2, which are connected to each other by means of flat iron-shaped connecting parts 133 at the ends by screws 134. Instead of benches, seat holders can be used.

The bench holder 135 has a circular tube recess 136 in the foreground. At its lower end 136.1 there is a U-shaped, downwardly open fastener 137 which is inserted into the base support 111 and secured to rise by a screw 138 or bolt below it, or by other means. The holder 135 has a rectangular tube protrusion 141 at the rear, the lower end 142 of which is inserted between the sides 111.1 and 111.2 of the base support 111. At the bottom, it rests upwards in the web of the open, U-shaped base support 111. The pedestal bracket 111 is attached to the nose of the side pipe 140.4, not shown in the viewfinder. The holder 135 is attached to the side at the rear by an inlet tube 145 attached to the rear wall 146 of the rear tube end 141. The tube is at such a height that its inlet end 145.1 fits exactly in 1 and 4.

The base 155 of the bench formed by the flat iron connects the ends 136 and 141 of the pipe from above. The flat iron is welded to the seams 156. In the middle of its support surface there are 6 91657 abutments 157 formed or welded on top of the tubes at both ends, which, when placed on the common base 155, create longitudinal support for the benches and a gap 150 in the perforated plate 150. In the center of the base 155 is a recess 160 into which the perforated plate 150 of the cross-shaped fastening element 149 can be inserted. The fastening element 149 is such that its perforated plate support 163 can be inserted from above into the gap 162 between the boards 132.1 and 132.2 of the benches 131. Both ends of the support 163 have securing arms 164 projecting downwards adjacent to the base 155, as shown in particular in Figure 3. A perforated plate 150 is welded downward in the center of the support 163, and the support 163 is inserted into the mounting iron 165 of the flat iron forming the perforated plate 150, and the parts are welded together by seams 167 so as to form a cross-shaped fastening element 149.

A vertical wedge hole 166 is recessed thereon so that it is below the base 155 when the fastening element 149 is inserted. The wedge 152 can then be inserted and soldered in place, as shown in Figures 1, 3 and 7. It abuts the lower edge 166.1 of the hole 166 and the lower edge 155.1 of the base 155 and keeps the fastening element 149 firmly down. At the same time, it presses the connecting parts 133.1 and 133.2 firmly on the bench base 155. The stops 157 at the same time ensure them from longitudinal displacements. Such a small gap 168 is created between the ends of the benches. Its size corresponds to the strength of the perforated plates 150.

If the same bench supports or the like are also to be used at the ends of the long rows of benches, short solid pieces consisting of short pieces of board or the like and a connecting part 133 connecting them, which are secured by a fastening element 149 and a wedge 152, can also be inserted.

The manufacture of the cross-shaped fastening element 149 is very easy. The bench holders 135 are notably free of protruding parts that could interfere with packaging, transport, or construction. Nevertheless, a simple plug-and-wedge connection is created, which is easy to install and secure the wedge in place by grooving and easy to remove by removing it again. However, guests cannot just open it so that • there is little risk of the benches or their holders moving.
