Device capable of assisting old people in going up stairs and going down stairs

Abstract

The invention provides a device capable of assisting old people in going up stairs and going down stairs. The device comprises a stairway, a sliding rail type armrest, an X-Z driving mechanism and a seat mechanism, wherein the inner side surface of the stairway is provided with the sliding rail type armrest; the X-Z driving mechanism is arranged in the stairway to realize movement in an X direction and in a Z direction; the seat mechanism comprises a seat body, an idler wheel, a connecting seat, a lantern ring, a sleeve and a supporting mechanism; the seat body is cooperated in the sliding rail type armrest through the idler wheel and is connected with the X-Z driving mechanism; and the supporting mechanism is arranged on the bottom of the seat body. The X-Z driving mechanism drives the seat body to realize the movement in the X direction and in the Z direction, so that the lifting and the lateral movement of the seat body can be realized, the seat body lifts along the sliding rail type armrest according to the decomposition of the movement, the supporting mechanism on the bottom of the seat body supports the seat body, so that shearing force applied to the seat body since a user sits on the seat body can be avoided, and therefore, the device can be guaranteed to normally operate.

Description

technical field [0001] The invention relates to the technical field of assisting equipment for going up and down stairs, in particular to a device for assisting the elderly in going up and down stairs. Background technique [0002] Publication No. CN206457145U provides a trolley auxiliary device for going upstairs. This device achieves efficient trolley lifting operations through a relatively simple and stable structure. Compared with the prior art, it reduces the footprint of the entire device without affecting In the normal use of the original escalator, pedestrians can pass in both directions when there is no trolley lifting, which increases convenience, but the trolley moves in the guide rail and is lifted by chain transmission, so the rotation of the trolley cannot be realized, so the lifting range Only one floor, and when the trolley is loaded with heavy goods, the weight of the goods will be applied to the trolley to form a shear force, so it is prone to bending defor...
