Manual self-help stair climber

Abstract

The invention discloses a manual self-help stair climber which is a special device used for helping some of the old or people who cannot move with the lower limbs conveniently in depending on their own abilities to climb stairs. The manual self-help stair climber is formed by compositing a flat-ground walking aid and stair climbing mechanisms, wherein the flat-ground walking aid is made of light metal pipes, and the stair climbing mechanisms are installed in the rear struts of the flat-ground walking aid. The stair climbing mechanisms are formed by combining two ratchet box components, two control lever components, two lifting pipes and two sliding rod components. The mechanics principles of levers and movable pulleys are adopted, ratchet mechanisms are arranged, and the up-down reciprocating motion of the arms is transformed to the effects for lifting the human body, so that the stair climbing effects of rising step by step are achieved. The manual self-help stair climber is simple in structure, easy to manufacture and convenient and reliable to operate, especially does not need extra power and integrates multiple functions.

Description

technical field [0001] The invention relates to a family health care appliance made of metal pipes, which is a device specially used to help some elderly people or people with handicapped lower limbs to climb stairs relying on their own ability-a manual self-help stair climber. Background technique [0002] The growth rate of the elderly population in our country is in the fastest period in history. Providing convenient walking equipment for the elderly has become one of the problems that we urgently need to solve. At present, there are walking aids for various elderly people in the domestic and foreign markets. , wheelchairs, trolleys, stair climbing devices, etc., but the walking aids can only be used on flat ground, and the stair climbing devices are mostly imitated foreign electric products. They are not only complex in structure and large in size, And the cost is expensive. For example, the track-type mechanical stair climbing device is to install rails on the stair bui...

Problems solved by technology

[0002] The growth rate of the elderly population in our country is in the fastest period in history. Providing convenient walking equipment for the elderly has become one of the problems that we urgently need to solve. At present, there are walking aids for various elderly people in the domestic and foreign markets. , wheelchairs, trolleys, stair climbing devices, etc., but the walking aids can only be used on flat ground, and the stair climbing devices are mostly imitated foreign electric products. They are not only complex in structure and large in size, And the cost is expensive. For example, the track-type mechanical stair climbing device is to install rails on the stair building, so that devices such as wheelchairs can move up and down the stairs along the rails. Like a small tank vehicle, it is more heavy and complicated. In addition, their common disadvantage is that they must use power or internal combustion engines as power, and the manipulation must be trained

[0003] Old age starts with old feet. Generally, the legs of the elderly aged 70-85 begin to decline first. Their lower limbs and knees are weak. They can walk on flat ground, but it is difficult to lift their legs to climb high. However, the arm strength of these elderly people is not bad. They account for the majority of the elderly. At present, many of them live in small high-rise buildings without elevators. They can walk down the stairs independently, but it seems powerless to go back upstairs. Therefore, with innovative ideas , for them to design and develop a kind of device that is easy to operate, does not need energy, and can easily go upstairs by relying on its own arm strength is a top priority, and it is also the goal that the inventors are diligently pursuing.
