Description

Folding seat in elevator car

Technical Field

The invention belongs to the technical field of elevators, and particularly relates to a folding seat in an elevator car.

Background

The elevator is used for taking passengers or carrying goods in the multi-storey building, so that people can go upstairs and downstairs and daily carry articles are greatly facilitated. Because the elevator inner structure is a standing cavity for passengers to stand, the elevator is required to carry a chair when taking the elevator for some patients and old people inconvenient to walk, and thus the elevator is inconvenient for the patients and the old people to move. In some places, a chair is temporarily arranged in an elevator, and the chair is moved into the elevator when the elevator is needed, and is moved out when the chair is not needed. The chair is inconvenient, if the chair is always in the elevator, the use of the elevator by other people is easy to be influenced, and the chair is easy to move in the elevator car which runs, so that the safety is low.

Disclosure of Invention

The invention aims to provide a folding seat in an elevator car, which can not move randomly in the elevator, has high safety and solves the problem that a special crowd is not suitable for riding the elevator in a standing position.

The object of the invention is achieved in the following way: the utility model provides a folding seat in elevator car, includes seat, back side support and preceding landing leg, the back side support includes the back landing leg of two vertical settings, and the upside of back landing leg transversely fixes an entablature, and preceding landing leg articulates the front side that sets up at the seat, and the rear side of seat articulates with the back landing leg, is provided with two connecting rods parallel with the seat in addition, the both ends of connecting rod are articulated with preceding landing leg and back landing leg respectively, and seat, preceding landing leg, back landing leg and connecting rod constitute parallel four-bar mechanism, and the upper portion medial surface of two back landing legs is fixed and is provided with U-shaped track, and the orbital rail mouth of two U-shapes is opposite to be set up, and two U-shaped track direction supports the back that can slide from top to bottom, and the rear end face left and right sides of back is equipped with the upper limit piece and lower limit piece of evagination, the entablature is located between upper limit piece and the lower limit piece, and the left and right sides of entablature respectively sets up an elasticity separation blade, and the downside end of elasticity separation blade is fixed with the separation blade with the thickness of slightly perpendicularly and directional preceding separation blade, separation blade.

A plurality of bonding disks are fixed on the rear supporting leg through bolts, and the back side support is fixed on the side wall of the elevator car through the bonding disks, so that the elevator is prevented from shaking in the running process.

The chair surface comprises a rectangular frame, a plurality of supporting bars are arranged on the inner side of the rectangular frame, a seat board is embedded above the supporting bars in the rectangular frame, and leather or sponge is preferably wrapped on the seat board. The front side end of the rectangular frame is hinged with a front supporting leg, and the rear side end of the rectangular frame is hinged on the inner side of the rear supporting leg. A distance matched with the thickness of the backrest is reserved between the front side back of the rectangular frame and the front supporting leg. When folded, the backrest falls down and is blocked on the back of the front side of the chair surface. After folding, the rectangular frame and the front leg are located between the two rear legs.

A front cross beam is arranged between the two front supporting legs, a rear cross beam is fixedly arranged between the two rear supporting legs, and the front cross beam and the rear cross beam play a supporting and reinforcing role.

The upper end of the backrest is fixed with an upper lifting handle, and the lower side end of the front cross beam is fixed with an outer pulling handle.

The lower end of the front supporting leg is provided with a rubber sleeve or a sucker, and the front supporting leg plays a role in supporting and damping in the downward moving process.

When the backrest is used, the backrest is pulled upwards through the lifting handle, the bottom of the backrest breaks away from the blocking effect on the seat surface, the outer pulling handle can be pulled to unfold the seat surface, at the moment, the blocking tongue moves forwards under the action of the elastic blocking piece, and the blocking tongue is blocked on the bottom edge of the backrest, so that the backrest is in a high-position state. When the chair is folded, the handle is pulled outwards by hand to enable the chair to swing backwards and upwards, the upper end face of the front side of the chair surface pushes the blocking tongue backwards to move backwards, the blocking tongue is pushed to enable the blocking tongue to be separated from the support of the backrest, the backrest falls down and is blocked at the front part of the chair surface, the front part of the chair surface is limited by the elastic blocking piece, and at the moment, the lower end face of the upper limiting block abuts against the upper cross beam to prevent the chair surface from being unfolded.

The beneficial effects of the invention are as follows:

the back side bracket is fixed on the side wall of the elevator cabin through the plurality of bonding plates, and the seat surface can be folded and can be stored in the back side bracket after being folded, so that the elevator can not be influenced by other people, and the backrest falls down and is blocked at the front part of the seat surface to prevent the seat surface from being unfolded. The seat and the back side support can not move in the elevator car when the elevator runs, so that the elevator is safer. When the backrest is in the unfolding state, the blocking tongue moves forwards under the action of the elastic blocking piece and is blocked on the bottom edge of the backrest, so that the backrest is in a high-position state, and a rider can conveniently depend on the backrest. The lower end of the front landing leg is provided with a rubber sleeve, which plays a role in supporting and damping when in use. The folding type elevator is convenient to open and close, good in stability, small in occupied space after folding, free of moving in the elevator, high in safety and capable of solving the problem that a special crowd cannot sit in the elevator in a standing position.
