Liftable and foldable seat

Abstract

The invention discloses a liftable and foldable seat. The seat is characterized in that a lifting electric cylinder is vertically and fixedly arranged in the middle of a suspending device, the liftingelectric cylinder is used for driving a lifting device to vertically move along the suspending device, the lower portion of the lifting device is vertically and slidably connected with a guiding supporting device, the guiding supporting device is used for being matched with a ground rail arranged at the bottom to limit swinging of the suspending device and the lifting device in the horizontal direction, a cable distributing frame is arranged at the top of the suspending device, and the cable distributing frame is used for fixing cables and distributing the cables according to electricity utilization positions. According to the seat, the gravity centers of the suspending device and the lifting device are located in the middle of the rail, so that the situation that the passing smoothness in the rail is affected after the suspending device and the lifting device are stressed is avoided; the lifting device can slide up and down under the action of the lifting electric cylinder to lift arotary seat body; and the guiding supporting device is used for being matched with the ground rail arranged in a staircase, so that on one hand, the rotary seat body is supported, and on the other hand, bending moment generated by the rotary seat body is overcome, and the rotary seat body can smoothly and safely run.

Problems solved by technology

[0002] With the advent of an aging society, the problem of travel difficulties for the elderly living in multi-storey buildings without elevators is becoming more and more serious. The emergence of "suspended" elderly people directly affects the implementation of the home care model. In order to solve this problem, the current In some cities, there are some successful cases of installing car elevators outside the existing buildings. However, the installation cost of general brand installations is about 500,000 yuan when installing elevators outside the building. The cost is relatively high, and it takes up space after installation. Large, affecting the ventilation and lighting of low-rise residents, which is likely to cause disputes among neighbors. At the same time, the car elevator is a special equipment that needs approval from various departments before installation, and the building structure of the building where the car elevator needs to be installed must comply with the relevant planning and quality. Therefore, there are not many successful cases and it is difficult to popularize. For this reason, two villa stair elevators and relay elevators that can be installed in the stairwell have appeared on the market, but these two elevators occupy the effective space of the corridor. It affects the fire protection function of the stairs, and it is inconvenient to install. Therefore, according to the needs of ordinary residential residents and villas and the convenience of the elderly to travel, a design is designed that will neither damage the existing building structure nor affect the fire protection and traffic functions of the corridor. Transportation device is an urgent technical problem to be solved in this field

[0003] The Chinese invention patent application with the application number CN201710628090.2 discloses a stairway elevator. In this application, the applicant uses a three-dimensional chain to cooperate with a track and a motor as a driving device, and hangs a boom connected to the three-dimensional chain on the track. Seats, in order to realize the renovation and installation of elevators in the corridors of existing buildings, but after experiments, it was found that the structure of this kind of boom seat is relatively complicated, and the operating state is unstable. Therefore, the applicant has carried out continuous research on the seat, And proposed a liftable folding seat with simpler structure, more perfect function and more stable operation
