Embodiment

[0031] combine Figure 1 to Figure 5 , this embodiment provides a flat stair device, including a plurality of pedal bodies 2 that can be fitted on the external steps 1, a cam mechanism 3 that drives each pedal body 2 to move up and down, and the cam mechanism 3 to rotate The driving mechanism 4; the rotation of the pedal body 2 through the cam mechanism 3 corresponds to the relative reciprocating lifting movement, and the two adjacent pedal bodies 2 can move to the same level. At this time, at least one of the pedal bodies 2 and its The corresponding steps 1 are arranged in close contact with each other. It should be noted that the operation of the driving mechanism 4 is controlled by a switch (not shown in the figure). The switch can be arranged on the side close to the user, manually opened by the user, or an induction switch is provided at the pedal body 2, and the switch controls the driving mechanism. The structure of 4 is the prior art, and will not be repeated here.

Abstract

The invention provides a flat-step stair device and relates to the technical field of stair devices. The flat-step stair device comprises multiple pedal bodies which can be attached to each external stair adaptively, a cam mechanism by which each pedal body is driven to do lifting movement and a driving mechanism which rotates the cam mechanism. Among adjacent pedal bodies, via rotation of the cammechanism, the pedal bodies are driven to do relative reciprocating lifting movement correspondingly so that every two adjacent pedal bodies can move to the same horizontal height; and besides, one or more pedal bodies are configured in a manner that the pedal bodies are attached to the corresponding stairs. According to the flat-step stair device, no new installing space is needed to be opened up, and the device can run after being installed on original stairs; moreover, the device is simple in structure, low in the installing cost and convenient to maintain; and besides, the need for simultaneous use by multiple people can be met, and thus the problems that it is difficult to go to a high floor without an elevator and it is inconvenient for the old to go upstairs and downstairs are solved.

Description

technical field [0001] The present invention relates to the technical field of staircase devices, in particular to a flat-step staircase device. Background technique [0002] With the development of the times, elevators, a device that is convenient for going up and down stairs, can be seen everywhere. It has to be said that the existence of elevators facilitates people's lives. The existence of elevators is particularly important when people go up and down high buildings and move things. However, some old high-rise buildings do not have space to refit elevators, and some users are affected by elevator safety accidents and worry about potential safety hazards due to insufficient elevator maintenance. Some families cannot afford the cost of installing elevators, so that they maintain the use of stairs to go up and down. Buildings abound. [0003] It is acceptable for most people to go up two or three floors of stairs, but there are not a few people who go up high floors, espe...
