Abstract

A chair for halls and stadiums is proposed, comprising a backrest, a folding seat, at least one support post and an arm on which the seat is mounted. The bracket and backrest are attached directly to the support stack, which simplifies the design of the chair. In the chair, the backrest and seat have frames in the form of metal frames, which give the design of the chair increased rigidity and strength. The soft elements of the seat and back are stitched, and the seams give them additional strength and wear resistance. The back surface of the back is protected by a metal sheet, which protects its integrity and appearance from sloppy spectators

Description

The utility model relates to the field of furniture industry, and more precisely, to chairs for sports and concert halls and stadiums.

Known chairs with folding seats (USSR author's certificate No. 264641 "Armchair", USSR author's certificate No. 1777805 "Section of seats with folding seats", RF patent No. 2189163 "Wall chair with folding seat"). Armchairs contain folding seats, backs and support racks. The closest seat is the “Tilting Seat with a Medium Height Back” by RAITA (Prospect “System of stands for ice arenas.” RAITA Sport Joint-Stock Company, Ratamestartinstvo FIN-86300, Oulainen, Finland), which was adopted as a prototype.

The bearing parts of the seat and back are made of sheet metal material. The support post has a U-shaped shape, the backrest is attached to the support post using a separate part - the connecting corner of the backrest - and fasteners. The fastening of the seat to the support column is also carried out using a separate part of the connecting corner of the seat.

The chair for halls and stadiums 1 is shown in FIG. 1 with the seat down (front view), in FIG. 2 with the seat up (front view), in FIG. 3 with the seat up (rear view). The chair contains a hinged seat 2, a backrest 3, a hinge device 4 and a support post 5. A support 6 is attached to the support post 5, which is used to fasten the hinged seat 2 using the hinge device 4, which allows you to raise and lower the hinged seat 2.

The support post 5 has holes 26 for attaching the chair to the vertical part of the comb of the stands of the hall or stadium. If the chair is installed in a room with a flat floor, then the support column contains a thrust for attaching the chair to the floor (not shown in the figures).

An adjacent armchair in a row of armchairs (the adjacent armchair is not shown in the figures) can be attached to the support post 5 in a similar manner. The extreme chair in a row has two support posts 5. Preferably, the support post 5 was made of a closed metal pipe of rectangular cross section, which increases its strength.

On the bracket 6, the axis 7 of the hinge device 4 is strengthened (Fig. 4). For adjacent seats there is one bracket 6, and the axis 7 can be made in the form of an axis 17 with two protrusions located on both sides of the bracket (figures 1 and 4).

The hinge device 4 is intended for fastening the folding seat 2 to the bracket 6 with the possibility of its rotation around the mentioned axis 7.

The hinged seat 2 contains a metal frame 10 of the seat, on which is mounted a soft supporting element 11 of the seat. In the metal frame 10 of the seat 2, a part of the hinge device 15 is installed with an opening for the axis 7, which can be made either in the form of a sleeve 24 (Fig. 5), or in the form of a tube 25 fixed to the bottom of the seat 2 (Fig. 6).

The folding seat 2 also contains a counterweight 12 (Figs. 1, 5 and 6), which is located on the adjacent to the back part 14 of the metal frame 10 of the seat 2, abuts against the end of the lower part 18 of the side element of the metal frame 8 of the backrest 3, when the viewer is sitting on the seat 2, allows the seat 2 under the influence of gravity of the counterweight 12 to take a vertical position when the viewer rises from the chair.

The backrest 3 is made in the form of a metal frame 8 with a soft supporting element 9 fixed on it (Figs. 1, 2, and 3). The lower part of the side element of the metal frame 8 of the backrest 3 is attached to the support post 5 and is an emphasis for the folding seat 2 when it is lowered (figure 3).

The soft supporting elements of the backrest and the folding seat (9 and 11) contain upholstery fabric, a lining, foam rubber or other similar soft material and plywood, and the soft supporting element is attached to the metal frame by screws screwed through the metal frame into a special nut fastened in plywood. Lining and upholstery materials are stitched together with vertical seams (figure 2).

The metal frames of the backrest and folding seat (8 and 10) are preferably made of rectangular pipes (there may be a round section).

The lower part 18 of the lateral element of the metal frame 8 of the backrest 3 is located at an angle of 11-15 degrees with respect to the upper part 19 of the lateral element of the metal frame 8 of the backrest 3 (FIGS. 2 and 3). This provides greater convenience for the location of the viewer in the chair.

The rear part 20 of the soft supporting element 9 of the backrest 3 is covered with a protective metal sheet (figure 3). The lower part 21 of the soft support element 11 of the seat 2 is covered with a metal sheet.

The upper part 22 of the metal frame 8 of the backrest 3 has a curved shape, which gives the chair a more aesthetic appearance. The lower part 23 of the soft support element 11 of the seat 2 can be covered with plywood covered with fabric.

Chair 1 operates as follows. When there are no spectators in the hall or in the stadium, the folding seats of the seats 2 are lowered (“tilted”) under the action of the counterweights 12 and are in a vertical position. When the viewer sits on the seat 2, it rises to a horizontal position and abuts against the emphasis 13 of the metal frame 8 of the backrest 3.

The metal frames (8 and 10) of the backrest 3 and the seat 2 make it possible to simplify the design of the chair 1, since with the help of the metal frames the backrest 3 is attached directly to the support post 5, and the folding seat 2 is attached directly to the bracket 6 without additional connecting parts. Metal frames 8 and 10 also increase the strength of the chair. The increase in strength is also ensured by the implementation of the support rack 5 of a closed metal pipe of rectangular cross section. Soft seat and back support elements (11 and 9), stitched with vertical seams 16, provide longer service life of the seat and back. The metal sheets protecting the lower part of the soft support element of the seat 21 and the back of the soft support element of the backrest 20 provide greater safety for the chair in case of careless or inappropriate behavior of the audience in the stadium. The practical applicability of the proposed utility model is confirmed by the fact that the manufacture of the proposed chair uses standard and widely known elements, parts, materials and technological processes.
