Abstract

(57) [Summary] [Purpose] To provide a wheelchair with a float that allows a physically handicapped person to run on the water surface by himself. [Structure] By fixing the connection fittings 9, 10, 13 of the float 7 to the frame pipe 1 of the wheelchair, the two floats 7 are detachably fixed to the lower positions on both sides of the wheelchair. Further, if the water scraping blades 14 are attached to the drive wheels 4 of the wheelchair and the hand rim 5 is operated and rotated, the water surface can be driven by itself.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wheelchair with a float that allows a person with a physical disability to travel on the water surface by himself.

[0002]

[Prior art]

 In addition to the conventional boats and foot-operated boats that have been known for a long time, devices for traveling on relatively quiet water such as ponds and lakes, as well as the actual Kaisho 61-59500 publication As shown, a structure in which a float is attached to a motorcycle and the propulsion means is driven by the rotation of the rear wheels of the motorcycle engine has been proposed. However, all of these conventional water-based traveling devices are aimed at healthy people, and it is impossible or dangerous for a person with a physical disability who normally needs a wheelchair to enjoy on their own. There was a problem.

[0003]

[Problems to be solved by the device]

 The present invention has been made to solve the above-mentioned conventional problems and provide a wheelchair with a float so that a person with a physical disability can enjoy traveling on the water by himself / herself without requiring assistance from another person. Is.

[0004]

[Means for Solving the Problems]

 The float-equipped wheelchair of the present invention made to solve the above-mentioned problems is provided with two floats provided with connecting fittings at the lower positions on both sides of the wheelchair by attaching the connecting fittings to the frame pipe of the wheelchair. The feature is that it is detachably fixed and that the driving wheels of the wheelchair are equipped with water scraping blades.

[0005]

[Action]

 The float-equipped wheelchair of the present invention is assembled by attaching the water-drapping blades to the drive wheels on both sides of a normal wheelchair and then attaching the float connecting fittings to the frame pipe of the wheelchair. If you devise a metal fitting, you can assemble it by yourself while you are on the car chair. Then, if the drive wheel is rotated by manually turning the outer rim of the drive wheel, the water scraping blade scratches the water to allow the water surface to travel gently on its own. Therefore, it is possible to enjoy running on the water surface without the need for special assistance.

【Example】

 Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. 1 is a front view of a wheelchair with a float according to an embodiment of the present invention, FIG. 2 is a side view with a part omitted, FIG. 3 is a plan view, and FIG. 4 is a rear view. In these figures, 1 is a frame pipe of a wheelchair, 2 is its seating surface, 3 is a foot rest, 4 is drive wheels on both sides of the frame pipe 1, 5 is a hand rim for rotating the drive wheel 4 by hand, and 6 is It is a front wheel.

Reference numeral 7 denotes a hollow plastic float that is detachably attached to the lower positions of both sides of the wheelchair of the wheelchair. A pipe 8 is fixed to the upper surface of each float 7 as shown in FIG. 3, and a part thereof hangs down along the inner side surface of each float 7 as shown in FIG. Further, a plug-in type connecting fitting 9 is provided at the tip of this hanging portion, so that it can be inserted and fixed in the rear portion of the frame pipe 1.

Further, as shown in FIGS. 1 and 3, a bag-type connecting fitting 10 is also provided at the front end portion of the pipe 8 on the upper surface of the float 7, so that it can be easily fixed to the front portion of the frame pipe 1. Is ready. Further, an arm 11 extending obliquely upward is provided at the center of the pipe 8 on the upper surface of the float 7, and it can be easily fixed to a handle 12 extending upward from the frame pipe 1 by a buckle-type connecting fitting 13. . The structure of these connecting fittings 10 and 13 is shown in an enlarged scale in FIG. As described above, the float 7 is fixed to the frame pipe 1 at the three locations of the connection fitting 9, the connection fitting 10, and the connection fitting 13, but these are plug-in type and buckle type, so the limb People with disabilities can assemble by themselves while still in a wheelchair. The frame pipe 1 of the wheelchair is constructed such that the three pipes 8, 11 and 17 extending from the pipes 8, 8 on the upper surface of the float 7 form an integral and substantially triangular shape. Next, a connecting rod 15 for supporting the buoyancy received from the float 7 is installed on the frame pipes 1 on both sides of the wheelchair. In the assembled state, the lower surface of the float 7 is located slightly higher than the ground so that it does not interfere with traveling.

As shown in FIG. 3, the inner portion of the float 7 is recessed so as not to interfere with the drive wheels 4. Then, as shown in FIGS. 2 and 3, the drive wheel 4 is provided with a water scraping blade 14. These water scraping blades 14 are attached to the inner periphery of the hand rim 5 so as not to hinder the operation of the hand rim 5, and when the hand rim 5 is operated by hand, it is possible to run by scratching the water like an outer paddle boat. ing. For this reason, it is possible for a person with a physical disability to run on the water surface by operating the hand rim 5 while riding on a wheelchair. Further, the traveling direction can be changed by appropriately changing the rotation speeds and the rotation directions of the left and right drive wheels 4, as in the case of traveling on the ground. Further, since the arms 16, 11, 17 and the pipe 8 on the upper surface of the float 7 are integrally provided, the rigidity of the float 7, the pipe 8 and the arms 16, 11, 17 can be improved, and further the float 7 Since the pipe 8 on the upper surface is provided long in the front and back, the float 7 can be carried when disassembled.

[0010]

[Effect of device]

 The float-equipped wheelchair of the present invention configured as described above is configured such that two floats can be detachably fixed to the lower positions on both sides of the wheelchair by using the connection fittings. It has the advantage that you can assemble it on your own while riding on a wheelchair. In addition, because the driving wheels of the wheelchair are equipped with water scraping blades, it is possible to drive on the water surface by operating the hand rim and rotating the driving wheels as in the case of traveling on the ground. For this reason, there is an appropriate slope at the water's edge and a hardness that prevents the drive wheels from slipping in, and if there is a quiet water surface, people with disabilities can run on the water surface themselves without the need for assistance. You can enjoy. Therefore, the present invention has a great practical value as a solution to the conventional problems.
