An assembly which can be mounted to a wheelchair to provide easy removal of the drive wheels of a wheelchair comprises a connector block mounted on a wheelchair frame, which connector has a first orifice extending therethrough for receiving an axle of a drive wheel of a wheelchair and a second orifice extending therethrough and at least partially intersecting the first orifice. A drive wheel axle having an annular groove at one end extends into the first orifice of the connector block such that the annular groove aligns with the second orifice. A rod rotatable about its longitudinal axis extends through the second orifice of the connector block with at least a portion of the rod having a generally circular cross section and a slot therealong. The slot aligns with the first orifice of the connector block. A first arm is fastened to and extends radially from the rod and moves with rotation of the rod. A second arm is pivotaly linked to the first arm. A leg is pivotally linked to the second arm and slidably mounted to the frame. The leg cooperates with the rod, first arm and second arm to move between a surface-engaging position and surface-disengaging position upon rotation of the rod such that the rod intersects the annular groove of the axle when the leg is in the surface-disengaging position and the slot on the rod aligns with the first orifice and faces the annular groove of the axle when the leg is in the surface-engaging position.

An assembly capable of mounting to a wheelchair in duplicate to provide removal of the drive wheels of the wheelchair, the assembly comprising: (a) a connector block mounted on a wheelchair frame, the connector block having a first orifice extending therethrough for receiving an axle of a drive wheel of the wheelchair and a second orifice extending therethrough and at least partially intersecting the first orifice; (b) an axle for a drive wheel having an annular groove at one end and extending into the first orifice of the connector block such that the annular groove aligns with the second orifice; (c) a rod rotatable about its longitudinal axis and extending through the second orifice of the connector block with at least a portion of the rod having a generally circular cross section and a slot therealong, which slot aligns with the first orifice of the connector block; (d) a first arm fastened to and extending radially from the rod and which moves with rotation of the rod; (e) a second arm pivotally linked to the first arm; (f) a leg pivotally linked to the second arm and slidably mounted to the frame which cooperates with the rod, first arm and second arm to move between a surface-engaging position and surface-disengaging position upon rotation of the rod, such that the rod intersects the annular groove of the axle when the leg is in the surface-disengaging position and the slot on the rod aligns with the first orifice and faces the annular groove of the axle when the leg is in the surface-engaging position.
