Description

The utility model relates to the field of construction, namely to collapsible constructions of seats for stalls and stands, which, when assembled, can be used for theater, sports shows and parades in open areas.

A known design of seats for the public, which contains two or more platforms with receiving parts for supports at the rear edge and supports supporting the protrusions included in the cutouts of the receiving parts and secured by the movement of the supports in a vertical position (abstract to US 6922947 BB, E04H 3/12, 08/02/2005, published in the Bulletin "Inventions of the World", issue 60, No. 15, 2006, p.14). The seats are collapsible, because only the back folds.

The disadvantage of the design of the seats is the material consumption of the structure, associated with a large number of racks, small parts in the form of protrusions, spikes, a complicated construction of the mounting device of the seats.

The closest solution to the claimed utility model is a collapsible seat for public buildings, which can be used as a chair for the auditorium, a bench for relaxing in the waiting room of the station, a sofa in the reception office (RU 2205582 C2, A47C 1/124, E04H 3/12, 06/10/2003). The seat consists of a one-piece metal frame in the form of a front part of the back, curved in length, and the actual seat, the back of the back, welded to its front part, and two metal bases welded to the side of the frame for the elbows. The frame (frame) is mounted on a metal support of four racks, which are attached from below to two bases - "skis", on the side - by means of two braces to the center of the frame. The seat can be made single, double, triple or multi-seat. Sections can be installed in a row and one after another and interconnected by means of fasteners (connecting devices) in the form of locks.

The known design due to the support of complex design is metal-intensive, heavy, difficult to assemble and has limited use, mainly for the assembly of public buildings.

The technical task of the proposed utility model is to create a simple collapsible seat design for the stalls and stands.

The technical result of the claimed utility model is to simplify the design, reliability and safety of its use for multiple assemblies and disassemblies at venues for spectacular events, and accelerate the transformation.

The technical result is achieved by the fact that the collapsible design of the seats for the stalls and stands includes technologically interconnected supports, a frame with seats for them and a connecting device mounted on them, while the supports are made in the form of vertical struts with braces, horizontal platforms are attached at the top of the racks with pins for the holes of the frame made of horizontal elements, rectangular plates with slots are fixed in the bottom of the racks for fastening these parts of the structure between of a connecting device, which is a horizontal profile pipe with two indented wedges attached indented from its edges downward at an angle of 90 °, which are inserted into the slots of the plates, and the numerical value of the indentation in mm corresponds to the formula “a = bd ”, where“ a ”is the indent,“ b ”is the distance from the outer surface of the pillar of the support to the end of the slot and“ d ”is the width of the wedge at the point of contact with the plate, with b> d.

The essence of the utility model is illustrated by the drawings in figures 1-4.

Figure 1 shows a General view of the prefabricated structure in assembled form in three projections: a - top view; b - front view; in - side view. Separately, a node is selected that shows the connection scheme (fasteners) of horizontal ties with vertical struts.

In all of FIG. structural elements are designated identically: 1 rack. horizontal platform 2 with pins 3 and plate 4 with slots, 5 braces, 6 frame of horizontal elements with openings 7, 8 profile pipe and 9 element in the form of a wedge.

Figure 2-4 shows the individual parts of the structure inoperative (disassembled).

Figure 2 shows a view of the support in two projections: a - front view; b - side view and a separate plate with slots - top view.

Figure 3 shows the frame in two projections: a - top view; b - side view.

Figure 4 shows two projections of the connecting device: a is a top view, b is a front view.

The collapsible design of the seats for the stalls and stands (one block) includes: two supports, a frame with seats for seats, a connecting device. The support consists of a vertical rack 1 with a horizontal platform 2 attached to it from above with pins 3 (for installing the frame), a plate 4 with symmetrical slots (for installing a connecting device), braces 5 for transferring the load and giving stability. The frame consists of horizontal elements 6 with holes 7 for fixing it due to the pins 3 on the support and transferring the load from the seats. The connecting device consists of a horizontal element in the form of a profile pipe 8 with attached, indented from its edges, downward at an angle of 90 ° to the longitudinal axis of two symmetrical elements made in the shape of a wedge, while the numerical value of the indentation, in mm, corresponds to the formula “a = bd ”, where“ a ”is the indent,“ b ”is the distance from the outer surface of the pillar of the support to the end of the slot and“ d ”is the width of the wedge at the point of contact with the plate, with b> d

All parts of the structure are made of metal.

The utility model works as follows. Frames with seats are laid out in a row in the amount corresponding to the width of the module.

The module, as a rule, is an assembly of 1 to 8 frames with seats.

Supports are installed sequentially from one edge with frames mounted on them. Then, to impart rigidity to the structure, connecting devices are installed.

As a result of simple actions, in a short assembly time, a rigid seat module is obtained.

Seats on the frame are fixed by known methods, the number of seats on the frame can vary from 1 to 5. Seats can be plastic chairs or a bench, in the latter case, plywood is pre-mounted on the frame.

To disassemble the structural elements, they go the opposite way: they remove the connecting devices, frames, after which the disassembled structural elements are stored until the next use during entertainment events.

Parterre halls of various sizes and configurations can be dialed from the modules. The stall can be installed directly at the venue at the "zero" level, at different levels, or on inclined platforms (with an angle of inclination of 2-3 °).

The claimed combination of features of the utility model allows to achieve the rigidity of the connection after assembly, with their high reliability and safety, to drastically reduce the time of assembly and disassembly of seats when picking stalls and stands.

The claimed utility model is mainly intended for widespread use in modern conditions for picking stalls and stands for theatrical performances, sports, anniversary celebrations, etc. in places that do not provide regular visits to viewers.
