Description

Article carrying walking aid capable of descending on stair railing

Technical Field

The invention relates to the field of intelligent auxiliary devices suitable for aging, in particular to a carrying walking aid which moves along the upper and lower sides of a stair railing.

Background

With the continuous aggravation of global aging, the quality of life and health of the elderly are the focus of social attention. In daily life of the elderly, going up and down stairs is an unavoidable link. For the old people living in the multi-storey residential building in the old community, although the elevators are additionally arranged in part of the corridor, almost all the old people adopt a half-storey entrance mode, namely, the elevator stop storeys and the stair corner rest platforms are additionally arranged on the same horizontal plane, after the elevator arrives at the rest platform of the corresponding storey, the old people also need to walk upwards or downwards to walk half-storey walking stairs, and then the old people enter the entrance door.

As the physical functions of the elderly are reduced, the elderly can easily lose balance when carrying articles (such as buyers, returns home, etc.) up and down stairs, and the risk of falling and injury is increased. Some auxiliary devices for going upstairs and downstairs exist in the market, but the auxiliary devices are often used as simple elevator aid, and the product cost, the articles carried by the old and the physical demands of the old on going upstairs and downstairs are not fully considered.

The existing walking aid is usually independent of the stair railing, is independently provided with a track, and takes the form of a seat or a pedal, so that people can directly sit on the walking aid to transport the old to climb up and down stairs. However, on the one hand, such products are extremely expensive, requiring two to three tens of thousands of prices for running on a flight of stairs, which greatly limits their popularization. Secondly, since the elderly need to hold the handrails to keep balance, they still have difficulty in carrying articles and even buying vegetables and pulling a cart at the same time when going upstairs and downstairs. On the other hand, the old community is still occupied alone mostly by self-care old people, and moderate climbing can ensure the basic activity of the old people every day, strengthen the heart lung function and the leg strength, and is beneficial to physical and mental health. Therefore, the use of existing walk-assisting devices to directly transport the elderly up and down stairs is not the best option.
