Description

technical field

[0001] The invention relates to the field of living aids, in particular to a mechanical device for helping the elderly go up and down stairs. Background technique

[0002] According to statistics, in daily life, millions of people fall down the stairs every year, and there are many old houses in third- and fourth-tier cities, and elevator rooms are not common, so most people still live on the stairs. house. Older people are more likely to be involved in accidents than younger people and cause more harm. How to prevent the elderly from going upstairs and downstairs without accidents, so that the elderly can travel or go home safely has become an urgent problem that needs to be solved at present. The inventors collected data and analyzed the survey results, and found that the main reasons for the elderly to fall are: first, tripping, second, slipping, third, shaking and falling, followed by dizziness, stepping on stairs, and so on. The root cause is that the...

Examples

Embodiment Construction

[0024] combine Figure 1-7 As shown, a mechanical device for helping the elderly to go up and down stairs includes a strip-shaped track plate 1 for being installed on the inner surface of the stair parapet 0 and a rail plate 1 that can move along the length direction of the track plate 1. The walking assist mechanism 2. The track plate 1 is generally directly installed on the stair parapet 0 through expansion bolts. Of course, on the premise of satisfying the tightness, it is actually feasible to fix the track plate 1 by bonding, welding or the like.

[0025] like figure 1 As shown in the figure, the track plate 1 is provided with a zigzag strip-shaped guide hole 3 extending along the length direction of the track plate 1. The guide hole 3 is generally continuous, and each sawtooth segment is relatively independent. And the starting end of each sawtooth segment, as shown in the figure, that is, the lower end of each sawtooth segment, has a corner, and the corner is used for ...
