Abstract: A set of quick release hubs for wheelchairs for physically handicapped persons with hemiplegic disability, characterized by two identical inserts (D1 & D2) located inwards from the hubs (M1 & M2) having quick release, being securely fastened into supports (10) provided on the wheelchair frame for the wheel location, each insert (D1 & D2) being coupled to each other on the inwards sides by an adjustable linkage system (1) and fitted on the other sides against the hub (M1 & M2) of the wheels (R1 & R2) of the wheelchair, one (D1) of the inserts including a drive collar and hand rim (18) for the handicapped person, thereby forming a drive system while the other insert (D2) being a driven system; the other rotation being provided directly on the outer hand rim (23) connected to the wheel (R1) thus placing the controls of the wheelchair motion on one side.

Abstract: In the hub body (1) of a wheelchair wheel hub, a quick release system is operated axially by a pushing member (6) to enable its positioning on a supporting structure. The wheel hub features, on the opposite end of its mounting side, a deep cavity allowing the positioning (placement) of a shaped ring in a set position (12-16), the latter providing the positioning and/or the guiding of a pushing member susceptible to cooperate with the locking/un-locking mechanism of the hub quick release axle, and in that a complementary mobile cap (14-18) is movable in reference to a fixed surface (12-16) with regard to control the intervention or not on the locking/un-locking mechanism of the hub.
