<p>PROBLEM TO BE SOLVED: To solve a problem that though there is disclosed a technology which opens and closes a footrest of a wheelchair by a remote operation, or facilitates the landing of the footrest and the getting-on/off of a patient by using a link mechanism, hydraulic pressure or the like, the technology is not widely diffused since the landing of the footrest is unclean for the patient, and it is indispensable for the patient to be assisted in the ascending and descending of both legs because the patient must bend his/her body when ascending and descending both the legs, also the link mechanism is complicated in structure and operation, and high in expense, and thus the distress of the patient and a caregiver is not improved.SOLUTION: Two front wheels of a wheelchair are reduced in speed by using a pair of male and female screws, or combining the screws to a pair of gears and timing pulleys, and the two front wheels are made ascendable and descendable by being rotated forward or backward by an electric motor or manually. The whole wheelchair is inclined forward and a footrest is landed when the front wheels ascend, and the wheelchair can be recovered to a normal posture before the forward inclination when the front wheels descend. Opening/closing of the footrest and ascending/descending of both legs become unnecessary while a patient leaves his/her both legs placed on the footrest, and getting-on/off the patient becomes safe and speedy.</p> |
