It is a perspective view which shows the fixing tool of the wheelchair traction apparatus of the 1st Example. It is a perspective view which shows the wheelchair traction apparatus of 2nd Example which concerns on this invention. It is a side view of the wheelchair traction device of the second embodiment.

  The wheelchair towing device in the embodiment of the present invention is for a person on the side of assisting to pull the wheelchair from the front of the wheelchair.

  Hereinafter, Example 1 will be specifically described with reference to the drawings. FIG. 1 is a perspective view showing a wheelchair towing apparatus according to a first embodiment of the present invention. FIG. 2 is a side view of the wheelchair towing device of the first embodiment. FIG. 3 is a perspective view showing a fixture of the wheelchair traction device of the first embodiment.

  The wheelchair coupling device 1 in FIGS. 1 to 3 includes a fixture 10 and a traction bar 20. As shown in FIG. 3, the fixture 10 includes a receiving part 12, a holding part 14, a pressing part 18, a bolt 17, and a bolt handle 16. The fixture 10 penetrates and penetrates through a cylindrical receiving portion 12 into which a tow bar 20 described later is inserted, a grip-like hold portion 14 provided on the side of the receiving portion 12, and the hold portion 14. A bolt 17 and a pressing portion 18 provided at the tip of the bolt 17 and in contact with the vertical frame 82 of the wheelchair 8 are provided. A bolt handle 16 for manually rotating the bolt 17 is provided at the bolt head of the bolt 17.

  The position where the fixture 10 is mounted on the wheelchair 8 is immediately above the caster column 88 that supports the axis of the caster 87 of the vertical frame 82. That is, the vertical frame 82 is at a relatively low position. When the fixture 10 is attached to the vertical frame 82, first, the holding unit 14 is covered along the outer periphery of the vertical frame 82. Then, when the bolt handle 16 is turned, the bolt 17 pushes the pressing portion 18 toward the inner surface of the holding portion 14, and the vertical frame 82 is formed between the inner surface of the holding portion 14 facing the pressing portion 18 and the pressing portion 18. By pressing, the fixture 10 is clamped to the vertical frame 82. Note that the positional relationship between the holding portion 14 and the receiving portion 12 of the fixture 10 is such that when the fixture 10 is mounted on the vertical frame 82, the receiving portion lower end 12 a of the receiving portion 12 of the fixing device 10 is the column of the caster column 88. It is preferable to be in a position where it can contact the upper end 88a.

  The tow bar 20 is a cylindrical bar having a length of about 350 mm to about 850 mm, and has a thickness of about 20 mm and a pole portion 22 having a thickness that can be inserted into the receiving portion 12 of the fixture 10. Near the upper end portion of the pole portion 22, there is a grip 24 that can be gripped by a person on the side of assistance. Note that a locking hole is formed in the side surface of the receiving portion 12 of the fixture 10, and the surface near the lower end of the pole portion 22 of the tow bar 20 can be locked in the locking hole of the receiving portion 12. A lock pin 26 urged so as to protrude upward on the outer periphery is provided. The pole portion 22 is inserted into the receiving portion 12, and the lock pin 26 is locked in the locking hole so that the pole portion 22 is connected so as not to come out of the receiving portion 12. Further, the tow bar 20 includes a band 28 that is a binding member for binding the tow bar 20 to the vertical bar 82 of the wheelchair 8. For example, the band 28 can be easily fixed if it is a bell bed fastener and can be bonded and fixed by winding it around itself.

  Then, in a state where the tow bar 20 is fixed to the wheelchair 8 via the fixing tool 10, the person who assists stands diagonally forward on the tow bar 20 side of the wheelchair 8 and holds the grip 24 while holding the grip 24. Try to draw 20. As a result, the assisting person can pull the wheelchair 8.

  As described above, according to the wheelchair towing device 1 of the first embodiment, the tow bar 20 stands from the vertical frame 82 above the caster column 88 of the wheelchair 8 and protrudes upward from the armrest 90 of the wheelchair 8. The person on the assisting side stands in front of the wheelchair 8 and pulls the wheelchair 8 while gripping the grip 24 provided on the wheelchair 8, so that the person on the wheelchair 8 can see the person on the assisting side, A person who is in the wheelchair 8 can obtain a sense of security that has never existed before.

  Moreover, when it is necessary to convey the two wheelchairs 8 alone, the tow bar 20 can be attached to the rear wheelchair 8 and used. Specifically, the person who assists stands between the wheelchairs 8 arranged at the front and rear, has the handle grip 86 of the front wheelchair 8 with one hand, and the tow bar 20 of the rear wheelchair 8 with the other hand. By grasping and pulling the grip 24, the two wheelchairs 8 can be transported. In this case, the back muscle of the person on the side of assistance is extended, and the burden of assistance is reduced.

  Furthermore, since the tow bar 20 can be detachably connected to the fixture 10, the tow bar 20 may be attached and detached as necessary. When the tow bar 20 is not used, it may be removed from the wheelchair 8. If it does not get in the way and it is desired to use the tow bar 20, it can be easily mounted.

  Further, since the tow bar 20 has the band 28 that is a binding member that binds the tow bar 20 to the vertical bar 82, the tow bar 20 is more securely attached to the wheelchair 8 by securing the band 28 to the vertical bar 82. Can be fixed.

  Note that the height of the upper end portion of the tow bar 20 (the gripping height of the grip 24) is 700 to 1200 mm above the ground with the tow bar 20 fixed to the wheelchair 8. For example, the selection may be made as appropriate. The optimum height is, for example, about 1050 mm above the ground and about 900 mm.

  Although the wheelchair towing device 1 according to the first embodiment is not configured to add another object to the tow bar 20, the second embodiment shows a form in which the person in the drip can use the wheelchair 8. Hereinafter, Example 2 will be specifically described with reference to the drawings. FIG. 4 is a perspective view showing a wheelchair traction device according to a second embodiment of the present invention. FIG. 5 is a side view of the wheelchair towing device of the second embodiment.

  The wheelchair coupling device 2 in FIGS. 4 and 5 includes a fixture 10 and a traction bar 30. The fixture 10 is the same as that of the first embodiment.

  The tow bar 30 has the same length as that of the tow bar 20 of the first embodiment and includes a grip 34 at the upper end of the pole portion 32. A stand hole 34a is formed at the upper end of the pole portion 32, that is, the upper end of the grip 34. It is installed. The stand hole 34 is a hole into which an infusion stand bar 62 having a hanging hook 64 for suspending the infusion bag on the upper side is inserted. And the lock bolt 34b for determining and fixing the height of the drip stand bar 62 inserted in the stand hole 34a is screwed onto the side surface of the pole portion 32.

  Then, in a state where the tow bar 30 is fixed to the wheelchair 8 via the fixture 10, the drip stand 60 is inserted into the tow bar 30, and the person on the side of assistance assists the front side of the wheelchair 8 toward the tow bar 30 side. Stand and pull the tow bar 30 while gripping the grip 24. As a result, the assisting person can pull the wheelchair 8. As described above, according to the wheelchair towing device 2 of the first embodiment, the wheelchair 8 can be towed even in a drip state.

  Note that the fixing tool 10 can be fixed to the lower rear part of the wheelchair 8, and the drip stand 60 can be raised behind the wheelchair 8.

  As described above, according to the present invention, the person on the assisting side stands and pulls in front of the wheelchair, so the person on the assisting side can be seen from the person on the wheelchair and is on the wheelchair. It is possible to provide a wheelchair towing device that allows a person to obtain a sense of security that has not existed before.
