Fall prevention stairs

Abstract

To provide a man-powered stair-climbing device and a fall prevention device that allow safe movement up stairs.SOLUTION: A safety device installed on existing stairs can prevent falls while reducing the effort required for ascending and descending stairs using foot and hand power in a fixed position, without stepping on the stair board.SELECTED DRAWING: Figure 3

Description

[Technical Field]

[0001] The present invention provides a stair climbing safety device as a measure to prevent the frequent occurrence of injuries and deaths caused by falls on conventional normal step stairs. [Background technology]

[0002] Even in typical Japanese houses, the construction requires moving up and down stairs like a ladder, requiring the use of one foot to push on each step, which makes the structure unstable.This problem was solved by using labor-saving foot pressure and manual steps in fixed positions. [Prior art documents]

[0003] Summary of the Invention [Problem to be solved by the invention]

[0004] This had the following drawbacks: When moving up and down stairs on staircases, people always use one foot, and even if they miss a step, there are still many serious accidents that result in them falling headfirst. Handrails are not sufficient to prevent falls from the upper floors. There are electric devices for moving up and down stairs, but the installation costs are high and it is difficult to spread them to all applicable houses.

[0005] We have developed a safety device that can prevent falls by simply stepping on existing stairs without stepping on the staircase boards and by manually stepping on the stairs in a fixed position.

[0006] It helps prevent falls and tripping accidents on stairs and provides peace of mind to people with weak legs at a reasonable cost. [Brief explanation of the drawings]

[0008] The following describes the embodiments of the invention. The fall prevention staircase of the present invention can be installed on existing stairs, and ascending and descending the stairs can be done with little effort, either by stepping on the stairs or manually, in a fixed position within the staircase ascending device.
