Description

Walking assist device for disabled elderly

technical field

The invention belongs to the technical field of walking aids, and in particular relates to a walking assisting device for disabled elderly people.

Background technique

When people enter old age, hearing loss, vision loss, visual field become smaller, sense of smell is not effective, sensitivity is slow, action is slow, gait is staggering, bone salt content in bones increases, bone fragility increases, osteoporosis, bone density decreases, Prone to fractures, cervical spondylosis, arthritis, frozen shoulder, lumbar spondylosis, muscle atrophy, cervical and lumbar joints are prone to hyperosteogeny, compression of nerves, causing pain and inflexibility of joint activities, skeletal muscles gradually weaken due to reduced activity Atrophy, reduced elasticity. All of the above diseases can cause pain in the legs and arms of the elderly, and bring a lot of inconvenience to the life of the elderly, especially the inconvenience of walking, the inability to exert force on the arms, and the inability to take care of themselves, which makes the life of the elderly very embarrassing.

China's national family planning policy and market economic situation affect people's lives. As the only child generation, the post-70s and post-80s are becoming young and middle-aged, not only shouldering social responsibilities, but also family responsibilities. China is aging In society, a young couple may have to support four or more elderly people. Young people have to work to earn money and take care of the elderly. The elderly are not cared for and can only take care of themselves.

Chinese invention patent (notification number: CN107157714B) discloses an auxiliary walking device, which includes a left frame, a right frame and an intermediate connecting rod. The finger lifts the wrench upwards to drive the fixed point of the synchronous belt to move upwards. The synchronous belt drives the synchronous wheel to rotate, synchronously The wheel drives the roller to roll along the ground through the one-way bearing, and the invention moves in the forward direction; release the wrench to drive the fixed point of the synchronous belt to move downward, the synchronous belt drives the synchronous wheel to rotate, and the synchronous wheel drives the outer ring of the one-way bearing to rotate , does not drive the rollers. The invention does not need to be lifted up and sent forward, and can be moved forward only by the force of clenched fingers with a small force, safe and reliable in use, and not easy to slip.

The above-mentioned patent can only move forward due to its own structure. When the user needs to move backward, such as when the user needs to go to the toilet, he can only directly pull the device, which is inconvenient to use.
