Description

The invention relates to medical equipment, in particular to means for the movement of patients and disabled people with impaired support functions for the movement of the lower extremities in indoor conditions and on paved areas, as well as stairs.

Known folding chair on wheels, containing side frames with wheels made to rotate relative to each other in the planes of the frames, struts connected to each other crosswise by means of an axis and lower ends of the hinged frames, seat and telescopic rods, consisting of a stationary and a movable part pivotally connected by means of sleeves to the upper ends with a cross and the lower ends rigidly to the frame; the stationary part of the telescopic rod is made in the cross section of a T-shape with a jumper, the movable part of the telescopic rod is made in the form of a square tube on one side, covering the jumper of the stationary part, and a separator is placed between the movable and stationary parts, the shape of which follows the shape the movable part, and the holes for placing the balls are spaced at the corners,

A wheelchair for the disabled is known, comprising a frame with two front and one rear wheels supporting a chair made of seats and backs hinged together.

A disadvantage of the known bells is the limitation of technological possibilities as a result of the insufficient maneuverability of bells.

The purpose of the invention is to expand technological capabilities and increase maneuverability.

This goal is achieved in that the frame is made of two L-shaped longitudinal elements rigidly connected by means of suspensions to the axis of the front wheels, the upper ends of the longitudinal elements of the frame are interconnected by stitches, which in turn are connected to a sleeve mounted movably with the possibility of fixing in the required position on a rack fixed to the rear of the frame, while the seat is fixed to the frame by means of cables and is spring-loaded with respect to braces connecting the axles of the front and rear wheels.

Figure 1 shows the proposed device; figure 2 is a view of figure 1.

The wheelchair for disabled people contains a frame 1 with two front 2 and one 3 rear wheels mounted on axle 4, seat c.

in the form of pivotally interconnected seats 5 and back 6, the frame 1 being made of two curved pipes 7 in the shape of a reclining position and rigidly connected to the suspensions 8, fastened to the axle 4 located on the front wheels 2, the upper ends of the pipes 9 are interconnected by stitches 10 interacting with a clutch 11 mounted on a rack 12, and the seat 5 is suspended on cables 13 passing from the bottom of the frame 1 through the suspension 3, frame 1, while the chair through the hole 14 of the tube 15 interacts with springs 16 mounted on a stretch 17.

When moving independently

patient with loss of mobility function,

. led in the chair for the rim 16, connected to

front wheels 2, rotates it with his hands,

0 the wheel moves in the direction it needs, to turn the wheel around, the patient rotates one of the rims and the wheel rotates in the desired direction.

With the help of an outsider

5 stitches 10 carts with the patient are moved up and down the stairs, if necessary, the patient should be in a prone position, reclining back 6 chairs are folded back, moving the clutch 11 on the rack 12

0 down, will take a reclining position, up in the upside, and having fixed the clutch in the middle, the patient will take a reclining position, the clutch will lower and rise up with the adapter 17.

5 bearings 18 mounted on an axis 19.

Wheelchair for the disabled can be made in dimensions; length from 1250 to 1370 mm, width up to 650 mm, height up to 1000 mm, with two front wheels 2 Ф600 mm, s

0 with one rear wheel 3 Ф-from 200 to 300 mm, one chair with a soft seat 5 and a back 6, two curved pipes 7 of any metal material, two suspensions 8 located on the front wheels, one cable 13 made of metal wire Ф 2.5 mm and raw belts of approximately 6-8 m.

The proposed wheelchair for people with disabilities allows you to expand technological capabilities by increasing the wheel maneuverability as a result of:

interconnection of the frame with all structural elements, since the frame is made of two bent pipes in shape

5 reclining, which allows for the production of wheels with minimal structural elements;

moving the wheel in any direction, as well as turning in place by fastening the frame with suspensions located on an axle located on the front wheels;

a formed rectangle between, which allows the chair to be placed, since the ends of the pipes are connected by stitches;

changing the position of the back of the chair from crawling to the lying position due to the interaction of the upper ends of the pipes with the sleeve mounted on the rack, it is necessary to adjust the back of the chair;

semi-rigid fastening of the chair, as the chair is suspended on cables passing

ram

I

from the lower part of the frame, through the suspension and lateral parts of the chair, to the upper suit of the frame, which ensures reliable fastening of the chair with the possibility of an angle between the seat and the back;

depreciation of the chair due to the interaction of the chair through the holes of the tube with springs mounted on braces, which

allows the seat to be amortized relative to the vertical axis, in the absence of rocking of the seat along the axis on which the front wheels are located.

Claims (1)

The claims Wheelchair for the disabled, comprising a frame with two front and one rear wheels supporting a chair made of pivotally interconnected seats and a backrest, characterized in that with the aim of expanding technological capabilities and increasing maneuverability, paiv the ski is made of two-shaped longitudinal elements rigidly connected by means of suspensions to the axis of the front wheels, the upper ends of the longitudinal frame elements are connected by stitches, which in turn is connected to a coupling mounted movably with the possibility of fixing the required position on a rack fixed to the rear of the frame, while the seat is fixed to the frame by means of cables and is spring loaded with respect to braces connecting the axles of the front and rear wheels.
