The utility model has the effects of not only being safer and more labor-saving to the passenger, not occupying the stair space, not influencing the normal up-and-down traffic of other people. When the power assisting device is not started, people can normally step on the lifting unit to go up and down stairs.

Description

Pneumatic stair booster unit

Technical Field

Stair booster unit, the utility model discloses install on the building stair that does not have the elevator for it is laborsaving to help people to walk up and down stairs.

Background

At present, the well-known stair power assisting device is characterized in that a rail unit is fixed on one side of a stair, and an electric lifting unit capable of moving up and down is arranged, so that people can go up and down the stair, and the effect of convenience and labor saving is achieved. Also known as corridor elevators. The prior corridor elevator provides labor saving and convenience for people to go up and down stairs, but has the problem that the track unit and the mobile unit of the corridor elevator occupy the limited space of the stairs. And the influence is caused to people who do not use the corridor elevator.

Disclosure of Invention

Technical problem to be solved

In order to solve the problem that the occupied corridor space influences other people, the utility model provides a new power assisting device for going upstairs and downstairs.

(II) technical scheme

This pneumatic stair booster unit, characterized by: including a plurality of pneumatic lift unit (2), pneumatic lift unit (2) have pneumatic lift unit upper plate (5) and pneumatic lift unit hypoplastron (9), have gasbag (7) that provide the power of raising between the two boards, a plurality of pneumatic lift unit settle in proper order on stair (1) lean on the step face at different levels of handrail one side, through compressed air pipe and control circuit pencil (3), advance exhaust solenoid valve (4) and connect in order, pneumatic lift unit (2) can go up and down in proper order, and the motion of stair about the personnel only need horizontal migration just can be accomplished.

The technical scheme of the utility model is (see each figure of description attached drawing), on the step face at different levels of the stair that ordinary stair leaned on handrail one side (hold the handrail at any time and ensure safety), settle pneumatic lift unit (2) respectively, the length of every unit slightly is less than the length that the stair step advances deeply, the width roughly is equivalent to the size that both feet stood immediately, the stroke that risees is equivalent to the height of step. Each lifting unit is orderly connected by a compressed air supply pipe, a control circuit wire harness (3) and an air inlet and outlet electromagnetic valve (4). When the passenger takes the train, a person stands on the pneumatic lifting unit upper plate (5) of the lower step, the lifting unit (2) rises, and the train stops when the lifting unit rises to the height equal to that of the lifting unit upper plate (5) of the higher step. The person can move horizontally to the upper plate (5) of the lifting unit which is higher than the steps. Repeating the above actions until the stair section is finished. Therefore, the passenger only needs to do horizontal movement with less force, and the movement of climbing stairs with larger force is completed. The descending mode is reverse in sequence and the principle is the same.

The utility model has the effects of not only being safer and more labor-saving to the passenger, not occupying the stair space, not influencing the normal up-and-down traffic of other people. When the power assisting device is not started, people can normally step on the lifting unit to go up and down stairs.

Detailed Description

The invention is further described with reference to the following drawings and examples (the examples described herein are only illustrative of the numerous embodiments of the invention)

The installation arrangement of this embodiment is as described above.

The compressed air supply pipe and the control circuit harness and the air inlet and outlet solenoid valves used in this embodiment are all made of known materials and controlled by known techniques, and are not described in detail.

The advancement of the technology is mainly realized by the pneumatic lifting units (2) arranged on each stair step, the length of each unit is slightly smaller than the depth of the stair steps, and the width of each unit is approximately equal to the size of standing with two feet. The stroke of the start lift corresponds to the height of the step.

When a passenger stands on the upper plate (5) of the pneumatic lifting unit stably, the air inlet and outlet electromagnetic valves (4) are opened (a known control method), the folding telescopic air bags (7) are used for air inlet to push the upper plate (5) and a human body to ascend, and in the ascending process, the four flexible height limiting cables (6) are in a loose and bent state and do not work. When the upper plate (5) rises to the same height as the upper plate (5) of the one-step higher lifting unit, the flexible height-limiting cable (6) of the pneumatic unit is tensioned, and the lifting stops. The person can move horizontally to the upper plate (5) of the lifting unit of the higher step. Repeating the above actions until the stair section is finished. The descending mode is in reverse order. When the air bag (7) is empty, the middle lower surface of the upper plate (5) is pressed on the lower supporting block (8) in the air bag, and the lower surfaces of the four frames of the upper plate (5) are pressed on the lower plate (9), so that the air bag (7) is not rolled when a person steps on the upper plate (5) of the pneumatic unit.

Claims (1)

1. The utility model provides a pneumatic stair booster unit which characterized by: including a plurality of pneumatic lift unit (2), pneumatic lift unit (2) have pneumatic lift unit upper plate (5) and pneumatic lift unit hypoplastron (9), have gasbag (7) that provide the power of raising between two boards, a plurality of pneumatic lift unit settle in proper order on stair (1) lean on the step face at different levels of handrail one side, through compressed air pipe and control circuit pencil (3), advance exhaust solenoid valve (4) and connect in order, and pneumatic lift unit can go up and down in proper order, and the motion of stair about the personnel only need horizontal migration just can be accomplished.
