A telescopic chassis and a rollator

Abstract

The invention discloses a walker, which belongs to the field of rehabilitation walking equipment. In between, the chain is fixedly connected with the movable chassis, the driving part drives the lifting mechanism to rotate relative to the frame to change the attitude of the rollator, the lifting mechanism drives the chain through the driving wheel, and the chain drives the movable chassis to move relative to the fixed chassis, so that the length of the telescopic chassis can be assisted. The driving posture changes are adjusted synchronously. When the person sits down, the telescopic chassis becomes longer to ensure that the user's center of gravity falls within the telescopic chassis to prevent backward leaning; when the person stands up, the telescopic chassis shortens to ensure maximum flexibility when the car body is in motion . The present application also relates to the above-mentioned telescopic chassis.

Description

technical field [0001] The invention relates to the field of rehabilitation walking aids, in particular to a telescopic chassis and a walker including the telescopic chassis. Background technique [0002] With the continuous development of science and technology and the increase in the number of people with lower extremity disabilities, the performance and types of walking aids are constantly improving and increasing. runner. Compared with the sitting walker, the standing walker can effectively prevent the user from being prone to pressure ulcers and muscle atrophy while sitting in a wheelchair for a long time, and also has a certain rehabilitation effect. [0003] The standing rollator assists the user to switch between sitting and standing through the lifting mechanism and the seat mechanism. However, since the user's center of gravity is different when using the rollator in the sitting position and using the rollator in the standing position, in order to prevent the cent...

AI Technical Summary

Problems solved by technology

[0003] The standing rollator uses the lifting mechanism and the seat mechanism to assist the user to switch between sitting and standing. However, since the center of gravity of the user is different when using the rollator in a sitting position and when using the rollator standing up, in order to prevent the center of gravity from moving backward when using the rollator in a sitting position The walking aids on the market will add a large amount of counterweight to the head of the body, generally 80kg-100kg, to balance the rearward movement of the center of gravity after a person sits down, which will lead to excessive weight of the vehicle. Large, inconvenient to use and transport, and a waste of energy

There are also some walkers, in order to ensure stability, the chassis is made longer, which increases the turning radius of the car body, which seriously affects the flexibility of steering and other actions at home or in some small spaces.
