摘要

Walkers for people with disabilities with a device for overcoming obstacles, such as stairs, consists of two U-shaped supports 1 passing through bushings 3 connected by a cross member 4. When folded, the walkers represent a flat bag. In the working position, the U-shaped supports 1 are arranged in parallel and fixed by a linear mechanism 4. For movement along the stairs, the U-shaped supports 1 are made of a L-shaped rack 7 and a straight rack 8, connected by an axis of rotation 9. The middle part of the rack 7 and 8 are connected by a sliding linear element 10 with a latch 11. The element 10 is seated at the edges on the axles 12, rigidly mounted on the uprights 7 and 8. In the lower part, the U-shaped supports 1 are made with extendable legs 13 with clamps 14. The legs 13 end with anti-slip supports 15 or two I or four wheels. In the upper part of the U-shaped supports 1, a length-adjustable belt 17 is fixed, forming a half-loop and having a movable support 18 in the lower part. One end of the belt 17 is fixed at the top of one support 1, and the other is tucked into the winch 19, fixed at the top of the other support 1 . In addition, the walkers can be equipped with retractable tubular axillary supports adjustable in height and inclination 22. The movement of the walkers on a flat surface is carried out by successive movement of the U-shaped supports to the beat 1. The use of walkers when moving along The shop is made in the following order: 1. when climbing the stairs, the angle between the L-shaped stand 7 and the straight stand 8, fixed by the element 4, is set in height, the front legs 13 are pushed in and the rear legs 13 are pulled out and fixed with latches 14, while the walkers are stably installed on the steps; 2. the belt 17 lowers to the middle or to the bottom of the step and is used either as a support for the leg, or for lifting with the help of a winch 19 people to the level of the next step, while the person freely moves to it; 3. walkers are rearranged to the next steps and the process is repeated, when moving down the stairs, the walkers are manipulated in the reverse order. Walkers with a winch can be used to lift a person to a small height, for example, the height of the bed, bathtub, threshold of the car, and so on. 4 s.p. f-ly, 1 ill.
