Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a mobile vehicle for people with disabilities that is mainly used indoors. This relates to a mobile vehicle for people with disabilities that can be operated by riding on the vehicle.

Prior Art Conventionally, it has been impossible to get into a wheelchair directly from the bed, and the reason for this is that the structure of the wheelchair means that the wheelchair cannot be entered unless it is facing backwards, making it impossible for disabled people with lame legs to get into the wheelchair without an attendant. Ta.

Traditionally, disabled people have been able to board the vehicle without getting up from the bed and onto the floor, which is a problem that the invention attempts to solve freely.In mobile vehicles, such as wheelchairs, which require disabled people to ride backwards, their legs cannot be used. A person with a disability who cannot stand could not ride the vehicle without an attendant. Therefore, the present invention aims to develop a mobile vehicle that can be easily boarded and exited by using the force of the arm.
A single-type front shaft 5 for steering that can be maneuvered as appropriate and a single-type rear wheel 1o for propulsion that can be operated in forward and backward directions and in forward and reverse directions are provided, and the vehicle moves from the rear shaft side to the front wheel side. 1) η A straddle-type seat 20 that is long in the front and back and narrow in the left and right is provided at the upper position in the rear direction, and the height from the running surface of this seat 20 from the middle part in the front and back direction to the front end of the aircraft is extremely low. Handrails 19a and 19b extend in the front and back direction at a position higher than the seat 20, with a step 32 for extending the seat 20 at a desired position, and providing a desired space on both the left and right sides of the seat 20 through which the left and right knees can freely pass.
The mobile vehicle for the disabled is provided with vertical gaps a and a formed between a seat 20 at the left and right intermediate portions and handrails 19a and 19b on both sides of the seat 20 on the rear side of the body 1 in plan view.

Functions and Effects of the Invention According to this invention, in order to get on the moving vehicle from the bed,
A person with a disability lowers both feet from the bed to the floor, leaves the chair resting open to the left and right, and backs up the vehicle, placing the rear end of the vehicle's seat at the edge of the bed between his left and right thighs. Join. At this time, the height of the seat is set to be approximately the same height as the bed height, or slightly lower.

In this state, the feet of the person with a disability remain on the floor due to the gap between the left and right sides of the moving vehicle, and the left and right hands can be easily transferred to the handrails on that side, allowing the handrails to hold the body and remain bent at the waist. People with disabilities can move forward using their own blades and ride along the handrail. At this time, since the bed and seat are continuous, you don't have to come to the car all at once; you can move slowly depending on your physical strength and gradually move, moving your feet forward and placing them on the steps. In this state, the front axle is appropriately steered to drive the rear wheels to move forward or backward to the appropriate location. In addition, to return to the bed, the user can easily return to the bed by backing up, bringing the rear end of the seat into contact with the bed, and performing the reverse movement.

Furthermore, this mobile vehicle is extremely effective when using the toilet, such as when defecating, and the user can easily move to the toilet side with the same operation as when returning to bed in a Western-style toilet, and can also transfer directly to the mobile vehicle.

As described above, this invention has the effect that, by the above-mentioned implantation, it is possible to get up from the bed, move forward by climbing on the handrail without turning backwards, and easily transfer to a mobile vehicle or return to the bed with one's own blade while bending at the waist. be effective.
