A manually operable hand braking device for such as but not necessarily confined to, a wheel (23) of a wheel chair. The device including a mounting member fixed adjacent the wheel periphery (23a), and a body part (5) mounted for partial rotation about an axis (7) of the mounting member (1) (2) extending transversely of the wheel (23); movement of the body part (5) being effected by a hand grip (26) and lever part (24), extending from the body part (5). The body part (5) being provided with two projecting spaced brake lock parts (21,22) disposed adjacent the wheel periphery (23a) or tire thereon, and arranged so that either of the brake lock parts (21 or 22) are engageable with the wheel periphery (23a) or tire on rotational movement of the body part (5), in one direction or the other, there being an intermediate position permitting freedom of rotation of the wheel (23). The arrangement and positioning of the brake lock parts (21,22) providing that engagement of one with the wheel periphery (23a) will prevent wheel movement in one direction and engagement of the other with the wheel periphery will prevent wheel movement in the other direction. There being locking arrangement (29 l) to lock at least one of the brake lock (21,22) in engagement with the wheel periphery (23a). The device also has applications for braking or restricting movement of such as the wheel(s) of other apparatus and such as ropes or belts.

A manually operable braking device for a wheeled conveyance comprising a mounting member arranged for fixedly mounting in close proximity to the periphery of a main support wheel of the conveyance, said mounting member having at least a part thereof in the form of an at least partly cylindrical bearing which is located as a slidable rotatable fit within a complementary substantially cylindrical recess of a main body part to support said body part for partial rotation about and relative to an axis of the fixed mounting member which is arranged for disposition transverse to the normal direction of movement of said wheel periphery, hand grip means mounted on said body part for effecting said partial rotation of the body part relative to the mounting member between at least first and second positions, and locking means associated with said hand grip means and mounting member for releasably locking said body part in either of said at least first and second positions; and said body part having at least one external brake lock part projecting therefrom and arranged to engage the wheel periphery to prevent movement thereof when said body part is moved to said first position, and said brake lock part being movable clear of said wheel periphery for freedom of movement with the body part in said second position.
