Abstract

Use: moving people with disabilities in various conditions. SUMMARY OF THE INVENTION: the device consists of a backrest 1, a seat 2, legs 3 with wheels 4, levers 7 with a support 8. The levers 7 are installed in the bushings 13, which, in turn, are pivotally connected to the bushings 11. The sleeve 11 is mounted on the axes 10; and the lever is equipped with a spring 9. 1 s.

Description

Fig, 1

The invention relates to medical equipment, in particular to devices for moving disabled people.

The purpose of the invention is to increase maneuverability. IDENTITY OF A STROLLER.

In FIG. 1 shows a general view of the cross; in FIG. 2 - the same in isometry; FIG. 3 is a section AA in FIG. 2.

The wheel consists of a chair in the form of a backrest 1, a seat 2 on legs 3 with wheels 4, a footrest 5 and two movement mechanisms in the form of a lever 7 with a pivotally connected support element 8, and an elastic element in the form of a spring 9.

An axle 10 is passed under the seat 2 of the chair, on which there are sleeves 11 mounted on both sides, which is connected through the hinge 12 to the lever 7. For this purpose, the guide sleeve is freely mounted on the lever at the seat level, which is made, for example, in the form of a plate 13 with bent ends, on which holes 14 are made, through which lever 7 is freely passed. Between the support element-outsole 8 and plastic 13, an elastic element 9 is mounted, for example, in the form of a compression spring. In this case, the hearth 7 has freedom of movement along the sides of the chair seat in a plane parallel to the side surface (rotating about axis 10), and 4 in a plane perpendicular to it passing through hinge 12 (see Fig. 3).

A colic is used as follows.

To bring the wheel in motion, the disabled person manipulates his hands, acting on the levers 7 forward, backward, sideways to himself or away from

themselves and choose any direction without the need for a U-turn. In this case, the compression spring 9 on the lever 7 facilitates the return of the levers to their original position, which ensures easy movement and maneuverability.

In order to overcome obstacles, for example, a threshold or stepping up stairs, the disabled person rests on levers set

vertically, about the floor. Due to the loose fit of the lever 7 through the holes 15 and due to the action of the compression spring 9, the disabled person is lifted along with the tightened seat on the lever 7, stepping over.

The design is colossal, assembled from light tubular elements, which makes it simple to manufacture. Thanks to maneuverability it can be used without

difficulties at home for both children and adults.

Claims (2)

Formula of the invention 1. Wheelchair for the disabled Containing a chair with legs, wheels pivotally mounted on the latter, two movement mechanisms, each of which is made in the form of a lever with a support element, which is based on the fact that to increase maneuverability, each lever of the movement mechanism is mounted to swing along and across and move in height relative to the chair and is equipped with an elastic element. 2. A wheel according to claim 1, characterized in that the support element is pivotally connected to the lever.
