Abstract

The foldable footrest of a wheelchair for the physically disabled is suitable for individual adjustment of the position of the patient's lower limbs. The footrest stroke is continuous throughout the entire range, i.e. from 0 to 90°. Adjustment is possible only by releasing the tip. The footrest as a whole can be rotated or completely removed from the wheelchair. The foldable footrest consists of a beam (4), which is slidably mounted in a housing (2). The footrest is hinged at the front end of the beam (4). The upper part of the footrest (5) is provided with a strut (7) passing through a clamp (8) located in the lower part of the beam (4).

Description

BACKGROUND OF THE INVENTION The invention relates to a foldable footrest of a wheelchair suitable for individually adjusting the position of the patient's lower extremities when the wheelchair is used.

Hitherto, foldable footplates are known in a wheelchair, wherein the upper part of the footboard is provided with a toothed segment into which the snap-fit engages. The push-in hooks into the toothed segment are generally spring-loaded.

The disadvantage of this condition is that the position of the footrest is limited by the number of teeth per segment. The withdrawal and retraction of the stand is demanding on the physical fitness of the patient and the whole construction is quite complicated and therefore also investment demanding.

These disadvantages are overcome by the solution according to the invention, wherein the folding footrest of the handicapped wheelchair consists of a beam which is slidably mounted in the housing. The position of the beam is secured by a tongue inserted in the groove of the housing.

The housing is fixed in the holder. The front end of the beam arm is provided with a pin on which the upper part of the footrest is hinged. The upper part of the footrest is provided with a strut, anchored in the tuft, detachably mounted in the groove of the lower part of the beam.

The T-shaped beam consists of a tubular web whose upper end is provided with a rigidly attached arm. The other end of the beam is provided with a grate. Haménko has the shape of a box cover, whose bottom wall is broken off. In the hollow of the arm, the tongue is firmly attached to the web. The sleeve in the form of a cylinder jacket is provided with a flange which is provided with at least two recesses, forming an acute angle 10 to 45 °.

An advantage of the arrangement according to the invention is that the stroke of the upper part of the footboard, and thus of the entire footboard, is completely smooth. Lifting the footrest to any position is possible only by releasing the clamp. Rotation of the footboard as well as removal of the entire footboard is made possible by loosening the screw in the holder. The footstool is structurally and therefore investment-friendly.

An exemplary embodiment of the invention is shown in the accompanying drawings, in which Fig. 1 shows a schematically depicted folding footboard of a wheelchair for a disabled in the home position; Fig. 2 the same footboard raised to a general position; Fig. 3 schematically showing a beam in front and section; FIG. 5 shows a cross-section of the housing and FIG. 6 shows a top view of the same housing.

The folding footrest of the wheelchair consists of a beam 4 in which the upper footrest section 4 is attached by means of a pin 4. The beam 6 passes through the housing 2 *. The housing 23 is mounted in a holder 2 which is attached to the sidewall 6. To the upper part of the footrest 5. a strut 2 extending through the tampon 6 is detachably connected in a groove 13 formed in the lower part of the beam 6.

The upper end of the tubular web is provided with a box-shaped arm 10, the bottom wall of which is broken off. In the hollow of the arm 10, the tongue 11 is fixedly connected to the web.

The sleeve 2 ^{in the} shape of the cylinder housing is provided with a recess 62 in the flange. The rod-like strut 2 is bent at a right angle at one end. The bent end of the strut 2 extends through the upper part of the footrest 5. while the other, straight end passes through the opening in the tuft.

The clip 8 is removably attached to the beam 8, namely to its lower end, i.e. in the groove 11. The foldable footboard of the wheelchair is used by loosening the screw in the holder 2 to fold up the footboard.

Clamp 2 is released to lower the footrest. · The upper part of the footrest X is set to the required position and the 8s® clamp is locked again. To remove the footrest completely, loosen the screw in the bracket χ. The clamp 2 is released further and the strut 2 is removed from the beam 6. Then, the stem as a whole is pulled out of the housing 6.
