One end of the pole 6 is provided at the tip of the pole 4 b and is supported by a support portion 7 that supports the pole 6. Further, the end 6b on the other end side of the pole 6 is supported by a placement portion 8 on which the pole 6 is placed. The placement unit 8 also has a function of placing the umbrella 50 when the umbrella 50 is not used.
A clip 9 that supports the umbrella 50 is provided at a substantially central portion of the pole 6.

The blowout portion in FIG. 1 shows the peripheral portion of the clip 9 in an enlarged manner.
The clip 9 includes a support portion 9a that supports the clip 9 with respect to the pole 6 and a holding portion 9b that sandwiches the hand 50a of the umbrella 50 when the pole 6 passes through the inside of the clip. The clamping part 9b can be opened left and right.

  The clip 9 is provided with a spring (not shown). The holding part 9b that opposes the force of the spring is opened to the left and right, and the hand 50a of the umbrella 50 is inserted into the holding part 9b so that the hand 50a of the umbrella 50 is supported by the clip. Is done.

  Further, a hook 11 that supports the end of the pole 6 when the pole 6 is not used is provided in the vicinity of the foot support 10b (in the present embodiment, the upper portion of the foot support 10b).

  Further, an insertion portion 12 is provided in the vicinity of the foot support 10a (in the present embodiment, the upper portion of the foot support 10a). The insertion portion 12 is inserted with the stone bump 50b of the umbrella 50 when the umbrella is not used.

Although not shown in FIG. 1, the hook 11 may be provided in the vicinity of the caster yoke 13b. Moreover, the insertion part 12 may be provided in the vicinity of the caster yoke 13a.
FIG. 2 is a diagram illustrating the wheelchair when the umbrella is not used.

When not using the umbrella 50, the user removes the hand 50 a of the umbrella 50 from the clip 9. Then, the pole 6 is removed from the mounting portion 8 and the tip of the pole 6 is hooked on the hook 11. The method of moving the pole 6 will be described in detail later.
On the other hand, the user places the hand 50 a of the removed umbrella 50 on the placement unit 8. Then, the umbrella butt 50 b is inserted into the insertion portion 12.
The blow-out portion in FIG. 2 shows an enlarged mounting portion that supports the pole.

  The mounting portion 8 is provided with a recess 8 a for mounting the pole 6. The shape of the end 8a1 of the recess 8a is formed corresponding to the shape of the circumference of the pole 6. That is, when the end 6b of the pole 6 is placed in the recess 8a, the pole 6 is supported by the recess 8a and does not wobble.

In addition, the placement portion 8 is provided with a recess 8b for placing the hand 50a of the umbrella 50 thereon. The recess 8b shares a part with the recess 8a. The shape of the recessed part 8b is formed corresponding to the shape of the hand 50a of the umbrella, and is a fan shape in FIG.
Next, the mechanism of the support portion 7 that supports the pole 6 will be described.

FIG. 3 is a diagram illustrating a mechanism of a support portion that supports a pole.
As shown in FIG. 3A, the end 6a of the pole 6 has a spherical shape, and has a diameter slightly larger than the central portion. The shape of the support portion 7 is such that the end portion 6a can be accommodated therein, and an opening 7a is provided in the left side portion, the near side portion, and the lower side portion in FIG. The size of the opening portion 7 a is smaller than the diameter of the end portion 6 a so that the end portion 6 a does not come off the support portion 7. Further, the end portion 6 a can be rotated inside the support portion 7.

In a state where the pole 6 is placed on the placement portion 8, the pole 6 is parallel to the Z-axis (the state shown in FIG. 3A). The user who has removed the pole 6 from the placing portion 8 rotates the pole 6 by 90 ° in the X-axis direction (front of the paper) with the support portion 7 as a fulcrum. Thereby, the pole 6 becomes parallel to the X-axis direction.
Thereafter, the end 6b of the pole 6 is hooked on the hook 11 by rotating the pole 6 in the Y-axis direction (downward in the drawing) with the support portion 7 as a fulcrum (state of FIG. 3B).

  In the present embodiment, an example of the mechanism of the support portion 7 has been introduced. However, the mechanism is not limited to the illustrated one as long as the end portion 6b of the pole 6 can be moved between the placing portion 8 and the hook 11. .

  Next, an operation when the user inserts the umbrella 50 using a wheelchair will be described. In the following description, a case where the umbrella 50 is a so-called jump umbrella will be described, but it goes without saying that a hand-open umbrella can also be used.

In the state shown in FIG. 2, the user first removes the end portion 6 b hung on the hook 11 from the hook 11 and rotates the pole 6 forward 90 ° with the support portion 7 as a fulcrum.
FIG. 4 is a diagram for explaining a moving pole.
Thereafter, the user rotates the pole 6 by 90 ° in the right direction when viewed from the user with the support portion 7 as a fulcrum, thereby bringing the end portion 6b of the pole 6 near the mounting portion 8.

Next, the user lifts the hand 50 a of the umbrella 50 placed on the placement unit 8, whereby the stone thrust 50 b of the umbrella 50 is taken out from the insertion unit 12. Then, the user places the end 6 b of the pole 6 on the placement unit 8.
Next, the user attaches the hand 50 a of the removed umbrella 50 to the clip 9.
Thereafter, the user opens the umbrella 50 by pressing a push button (not shown) of the umbrella 50.

As described above, according to the wheelchair 1, the user can easily put the umbrella 50. In addition, since the pole 6 is arranged at a position somewhat away from the user, it is difficult for the knee to hit the pole 6. For this reason, when the user operates the wheelchair 1 by himself / herself, the pole 6 does not easily get in the way.
A mechanism for accommodating the umbrella 50 was also provided. Thereby, even when the umbrella 50 is not used, there is no problem with the location of the umbrella.
In addition, the placement portion 8 also serves as a part of the accommodation mechanism of the umbrella 50. Thereby, the number of parts can be reduced.
