Description

Skeleton structure of the walker

The utility model relates to a skeleton structure of a rolling aid, which belongs to equipment for transporting patients or facilitating patients in the field of health care and entertainment.

Generally, the elderly or those who need rehabilitation due to accident injuries need to be supported to walk due to inconvenient movement. Usually, walking aids or walking chairs are used as walking aids. The early walking aids were only a rectangular frame. When walking, the legs cannot be supported and need to sit down to rest, because there is no structure for sitting down and resting, so it is inconvenient to use.

And because the traditional walking frame must be picked up and put down when walking, so that you can walk slowly step by step, but some old and weak people cannot lift the whole walking frame when walking, so they cannot use the walking frame to assist them. Walking, and because the traditional walking frame has four foot posts below it, if the four foot posts are not leaning against the ground at the same time, if you press against the walking frame and walk at this time, accidents of falling will easily occur.

In order to improve the shortcomings of the traditional fixed walking frame, rollers are installed on the four corner posts under the walking frame. When walking, it is not necessary to pick up the walking frame, and it is only necessary to push the walking frame with rollers to move forward. , and a seat is installed on the walker frame to become a rollator, but the general rollator is an integral type, and it is very inconvenient to carry it on the car if you want to go out; in addition, this ribbed walker cannot be disassembled, so its The volume is large, it is not convenient for packaging and handling, and it is not ideal for use.

The purpose of the utility model is to provide a skeleton structure of a rollator that can be disassembled and packaged, reduced in volume, easy to carry and carry, and capable of constituting a wheelchair.

The scheme of the present utility model is that two S-shaped front wheel rods are provided with springs opposite to each other, a front roller is installed at the pipe end below it, and a handle bar is provided above it, and a handle bar is provided at the end of the handle bar. A belt seat is installed, and between two opposite belt seats, the two ends of a strap are respectively pivoted on the belt socket to form a chair back, and a seat is placed in front of and above the two opposite S-shaped front wheel rods respectively. The cross bar is connected, and a pedal that can be turned over is installed on the front cross bar; the two へ-shaped rear wheel bars are arranged oppositely; and the lower pipe end of the へ-shaped rear wheel bar is equipped with a rear roller, and The two-shaped rear wheel frame is combined with a ∏-shaped chair frame, and the buckle rods on both sides of the chair frame are combined with the horizontal bar above the two-shaped rear wheel rod, and the two ends of the chair frame are pivoted. At the rear of the S-shaped front wheel bar, the front end of the chair frame leans against the cross bar above the S-shaped front wheel bar; in addition, a sheet seat cushion is installed on the chair frame.

The utility model has the advantages that the package can be disassembled, the volume is reduced, the utility model is convenient to carry and carry, and can form a wheelchair.
