Abstract

(57) [Summary] [Problem] To allow a seated passenger to stretch his knees to take a relaxed posture or a kneeling posture, and to reduce the turning radius of the body frame to enable rotation in a narrow place. The purpose is to provide wheelchairs. A base end of a leg pipe (9) is pivotally connected to a front end (8a) of a vehicle body frame, and the leg pipe (9) is rotatably mounted.
A wheelchair provided with a stopper 11 for adjusting the inclination of the leg pipe between the front end 8a of the vehicle body frame.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a wheelchair in which the inclination angle of a leg pipe can be adjusted independently of a body frame.

[0002]

[Prior art]

 As shown in FIG. 3, the conventional wheelchair includes front pipes 1, 1, seat pipes 2, 2, base pipes 3, 3, and axle support pipes 5 for large wheels 4, 4 erected on the base pipes 3, 3. , 5, and back pipes 6, 6, etc., constitute a body frame 8.

A leg pipe 9 is provided integrally with an extension of the seat pipes 2 and 2.

[0004]

[Problems to be solved by the invention]

 However, with the above-described configuration, the leg pipe 8 cannot be tilted independently with respect to the body frame 7, so that the knee cannot be extended or the knee cannot be folded.

When a wheelchair is rotated in a narrow place, it is necessary to reduce the radius of rotation as much as possible. In the conventional structure, it is necessary to reduce the inclination angle of the leg pipe 8 with respect to the body frame 7. Therefore, there was a limit to reducing the turning radius of the vehicle.

[0006] Therefore, an object of the present invention is to provide a wheelchair that can take a posture in which a knee is extended or folded, and can further reduce a turning radius of a vehicle body.

[0007]

Means for Solving the Problems In view of the above-mentioned circumstances, the present invention has a base end of a leg pipe pivotally connected to a front end of a body frame, and a space between the leg pipe and a front end of the body frame. Proposes a wheelchair with a stopper for adjusting the inclination of the leg pipe.

[0008]

[Embodiment of the invention]

 That is, according to this invention, the base end of the leg pipe is pivotally connected to the front end of the body frame, and a stopper for adjusting the inclination of the leg pipe is provided between the leg pipe and the front end of the body frame. As a result, the angle of inclination of the leg pipe with respect to the front end of the body frame can be adjusted.

Since the angle of inclination of the leg pipe with respect to the front end of the vehicle body frame can be adjusted, it is possible to sit in a relaxed posture with the knees extended, or to sit in a wheelchair with the knees folded.

Further, according to the present invention, the inclination angle of the leg pipe with respect to the vehicle body frame can be reduced, so that the turning radius of the vehicle body can be reduced, and the wheelchair can be rotated in a narrow place. To

[0011]

【Example】

 Hereinafter, the present invention will be described in detail based on the illustrated embodiment. 1, 1 is a front pipe, 2, 2 is a seat pipe, 3, 3 is a base pipe, 4, 4 are large wheels, and 5, 5 are large wheels. Axle support pipes for wheels 4 and 4, 6 and 6 are back pipes, and 7 and 7 are casters. Body frame 8 is front pipe 1, seat pipe 2, base pipe 3, axle support pipe 5, back pipe 6. And 8a is its front end.

Reference numeral 9 denotes a leg pipe provided independently of the vehicle body frame 8, and a base end of the leg pipe 9 is pivotally connected to a pivoting part 10 provided at a front end 8 a of the vehicle body frame 8. I do.

In this embodiment, the pivot portion 10 is provided at the tip of the seat pipe 2.

Reference numeral 11 denotes a stopper for adjusting the inclination of the leg pipe 9 provided between the leg pipe 9 and the front end 8a of the vehicle body frame. In this embodiment, the stopper 11 is a pin provided on the front end 8a side of the vehicle body frame. The pin 12 is provided on the side of the leg pipe 9 and has a locking member 13 for the pin 12. The locking member 13 has a locking groove 14 for locking the pin 12 in a stepwise manner.

The present invention is configured as described above. The leg pipe 9 is made independent of the body frame 8, and the base end thereof is pivotally connected to the front end 8 a of the body frame so as to be rotatable. Since the stopper 11 for adjusting the inclination of the leg pipe 9 is provided between the body pipe and the front end 8a of the body frame, the leg pipe 9 can be inclined at a predetermined angle with respect to the body frame. It is possible to take a position where the knee is extended or folded.

Further, in the present invention, since the inclination angle of the leg pipe 9 can be reduced with respect to the front end portion 8a of the vehicle body frame, the turning radius of the vehicle body is made smaller than that of the wheelchair having the conventional structure in FIG. And thus enable rotation of the wheelchair in tight spaces.

[0017]

[Effect of the invention]

 In short, according to the present invention, the leg pipe can be independently inclined with respect to the body frame, so that the occupant can take a posture of extending the knee or folding the knee. In addition, since the turning radius of the vehicle body can be reduced, the wheelchair can be rotated in a narrow place.
