<P>PROBLEM TO BE SOLVED: To solve the problem that, when an on-wheelchair person operates a wheelchair by him/herself, he/she directly grips self-propelling hand rims with hands, puts force on the rims, and rotates the self-propelling hand rims to transmit power to connected assistance wheels, thereby to perform an operation for advance, retraction, and stop, etc., but a physically-disabled person or an aged person having a walking problem with reduced strength, etc., extremely exhausts him/herself and is not fixed in a sitting posture when manually operating the wheelchair within a large range or in a place with steps. <P>SOLUTION: When the on-wheelchair person operates the wheelchair by him/herself, in place of a conventional manual operation, the self-propelling hand rims are rotated by the leverage with the use of drive levers arranged on both sides of the wheelchair to transmit the power to the connected assistance wheels, thereby to perform the operation for advance, retraction, and stop, etc. Consequently, a power introduction device solves the conventional problem of the physically disabled on-wheelchair person. <P>COPYRIGHT: (C)2013,JPO&INPIT |
