    Abstract: A wheel mount assembly for mounting a drive wheel to a frame of a wheelchair is provided. The assembly includes a camber body attachable to an axle of one of the drive wheels and operable to pivotably couple about the frame through a range of camber angles; a spacer operable to set a desired camber angle, the spacer contacting the camber body at the desired camber angle; and a clamp operable to secure the camber body and the spacer to the frame at the camber angle. Optionally, a transverse member, extending between the drive wheels, may engage a portion of the frame such that the clamp is prevented from pivoting through the camber angles of each respective camber body. Again, optionally, the wheel mount assembly may be clamped to the frame at a multitude of positions, thus providing a means to adjust the center of gravity of the wheelchair.

  • Patent number: 6682152
    Abstract: A wheelchair wheel locking system reduces the likelihood that a wheel will inadvertently disengage from the wheelchair. An axle is attached to the wheel and has a protrusion for engaging annular grooves within a wall forming an inner passage through an axle receptor attached to the wheelchair. The axle is inserted in an axial direction into the inner passage and has a first locked position in which the axle is fully engaged with the axle receptor, and a second locked position in which the axle is partially engaged with the axle receptor. If a quick release lock is inadvertently released by, for example, pressing a release button, the protrusion retracts and disengages from a first annular groove within the wall of the axle receptor, the axle may start to move axially relative to the axle receptor to a position in which the wheel will disengage from the wheelchair.
