Definitions

  • the present invention relates to wheelchairs and more particularly to apparatus to aid a user of the chair in propelling it.
  • a wheelchair propelling aid for wheelchairs having a number of wheels to be driven by a user of the chair, said aid including a movable hand grip having a grippable hand position so as to be gripped by the user of the chair, said grip to be adapted to be mounted on the chair so as to be movably engaged about the axis of the wheels and wheel engaging means fixed to said handle grip and selectively actuable from said end by the user so that the wheel can be gripped and driven by the user by pushing said end.
  • FIG. 1 there is schematically depicted a wheel 10 of a wheelchair, which wheel 10 is mounted on a central shaft 11 from which radially extend a plurality of spokes 12 which are fixed to an outer rim 13 which supports a tyre 14. Positioned adjacent the periphery of the tyre 14 is an aid 15 adapted to be manipulated by an occupant of the wheelchair in propelling the wheelchair.
  • the aid 15 includes a lever 16 adapted to be gripped by the occupant of the wheelchair and moved in a clockwise or anti-clockwise direction about the shaft 11.
  • a tyre gripping member 17 which is adapted to frictionally engage the tyre 14 so that upon the lever 16 being moved about the shaft 11, the wheel 10 is caused to rotate.
  • a linkage 18 which is pivotally coupled to the central shaft 11 and extends radially therefrom to a position radially outwardly of the tyre 14.
  • the outer extremity of the linkage 18 has a flange 19 through which the lever 16 may slidably pass.
  • Fixed to the lever 16 is a further flange 20.
  • Extending between the flanges 19 and 20 is a spring 21 which biases the lever 16 to a radially outer position.
  • the occupant of the wheelchair grips the lever 16 and applies a radially inward force to it to cause the member 17 to frictionally engage the tyre 14. Thereafter the lever 16 is pushed forward taking with it the wheel 10 thus propelling the wheelchair. Upon the lever 16 progressing to the forward limits of the users reach, the radial force is relieved thereby permitting the lever 16 to move to a radially outer position whereby the member 17 is no longer in contact with the tyre 14. Thereafter the aid 15 is returned to its initial position whereby it is again ready for frictional engagement with the tyre 14.
  • FIG. 6 there is schematically illustrated an aid 30 adapted to engage the tyre 14 so that a user of the aid 30 may cause rotation of the tyre 14 by frictional engagement therewith via the member 17 and lever 16.
  • the lever 16 is biased to a radially outer position by the spring 21.
  • the linkage 18 is provided with a generally U-shaped upper part 31 which substantially encompasses the radially outer peripheral surfaces of the tyre 14 so as to be retained in a position generally co-extensive with the tyre 14. This enables the linkage 18 to be provided with solely a passage 32 through which the shaft 11 passes.
  • a lever arrangement 40 having a first handle 41 fixed to the lever 18 and a second handle 42 pivotally coupled by means of a pin 43 to the first handle, which handles 41 and 42 are arranged to be gripped by a user of the wheelchair.
  • the member 17 is caused to move toward the tyre 14.
  • Extending between the member 17 and handle 42 is a shaft 44 which receives a pin 45 at its upper end, which pin 45 is received within a slot 46 formed in the handle 42.
  • a leverage mechanism 50 which includes a first handle 51 fixed to the lever 18. There is further included a second handle 52 pivotally coupled to the first handle 51 by means of a pin 53. Extending between the second handle 52 and member 17 is a shaft 54 which upon a user of the wheelchair grasping the handles 51 and 52 may cause the member 17 to frictionally engage the tyre 14.
  • the arrangement 50 includes two friction pads 51 which are brought into frictional engagement with the rim 13 so as to cause rotation of the wheel 10.
  • the friction pads 51 are attached to linkages 52 and 53 which are pivotally coupled to the lever 18 by means of pins 54.
  • the linkage 52 is provided with a slot 55 and the linkage 53 with a pin 56 which is slidably received within the slot 55.
  • Extending from adjacent the junction of the linkages 52 and 53 is a shaft 57 which may be caused to move upwardly by a lever mechanism to cause inward pivoting of the linkages 52 and 53 so that the pads 51,frictionally engage the rim 13.
  • FIGS 10 and 11 there is depicted a tyre gripping assembly 50 to be used in conjunction with a lever 51 to grip the tyre 52 of a wheelchair.
  • the assembly 50 includes a handle 53 to be gripped by a user of the wheelchair.
  • the handle 50 is provided with two slots 54 and 55 through which pins 56 and 58 may slide.
  • the pins 56 and 58 are fixed to the lever 51 by means of a bracket.
  • an adjustable tyre engaging member 57 which is threadably received within the passage formed in the handle 53. Accordingly, member 57 has an extremity which is adjustable relative to the surface of the tyre.
  • the assembly 60 is operated in a similar manner to the previously described devices in that a user of the wheelchair may operate the trigger 62 to frictionally engage the tyre 67 and thereby cause rotation of the tyre 67 to propel the wheelchair.
  • the other end of the cable 73 extends to a caliper assembly 75 including two pivoting brackets 76 which would be pivotally supported on the lever 72 so as to be movable between a position of non-engagement with the wheel and tyre 77 (as depicted in Figure 14) to a position frictionally engaging the wheel and tyre 77 (as depicted in Figure 15).
  • the two brackets 76 define in combination a cavity within which is located a movable part 79 fixed to the extremity of cable 73.
  • the member 79 upon being moved by the cable 73 causes pivoting of the brackets 76 from the position depicted in Figure 14 to the position depicted in Figure 15 whereby the tyre is frictionally engaged allowing a user of the wheelchair to cause rotation of the tyre.
