Definitions

  • the floor-side equipment can be minimized and the user of the wheelchair can fix the wheelchair alone or the caretaker can fix the wheelchair with a light burden, it is possible to improve the environment for the usage of the wheelchair.
  • the winding device includes the pulling device for pulling the linear member in the winding-up direction. Therefore, by operating the pulling device to pull the linear member in the winding-up direction, the tension generated in the linear member can be further increased. As a result, it is possible to firmly fix the wheelchair.
  • the springs 222 have functions of applying rotating forces in one direction to the rotors 221.
  • spiral springs are used as the springs 222 and two springs 222 are provided to respectively act on the first rotor 221 a and the second rotor 221b.
  • the canceling mechanism 225 has a function of canceling a locked state by the lock mechanism 224 and a structure of the canceling mechanism 225 is not restricted as far as it can perform the function. However, as the canceling mechanism 225, the mechanism having a structure that can maintain the cancelled state is preferable. In other words, if the lock mechanism 224 is actuated to lock the linear member when a hand for operating an operation portion of the canceling mechanism is released from the operation portion, both hands are always necessary for operation, i.e., one hand for operating the operation portion of the canceling mechanism and the other for holding the linear member 21.
  • the canceling mechanism 225 employed in the embodiment includes a bolt 225a disposed in such a position as to face the eccentric cam 224b, a bolt retaining portion 225b having a screw hole in which the bolt 225a is coupled, and an operation portion 225c provided to protrude from a head portion of the bolt 225a and can maintain the cancelled state by coupling between an external thread formed on the bolt 225a and an internal thread formed in the screw hole as shown in FIGS. 2 and 4 .
  • the operation levers 223a forming the pulling devices 223 are swung.
  • the first rotors 221a rotate in one direction to wind up the front belts 21 a, 21b and therefore the tension generated in each of the front belts 21 a, 21 b and rear belts 21 c, 21d is further increased to firmly fix the wheelchair 1.
  • the winding devices 22 are disposed at the lower portions of the armrests 1a and 1b and the operation levers 223a are under hands of the user of the wheelchair, the user of the wheelchair can operate the operation levers 223a by himself/herself.
  • FIG. 5 is a drawing showing a state in which a wheelchair 1 according to the embodiment 2 is fixed onto a floor.
  • the wheelchair 1 according to the present embodiment also includes the wheelchair fixing apparatus 2 having the linear members 21 and the winding devices 22 similarly to the wheelchair 1 according to the embodiment 1.
