ABSTRACT OF DISCLOSURE 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 tyre thereon, and arranged so that either of said brake lock parts (21 or 22) are engageable with the wheel periphery (23a) or tyre 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 means (29) to lock at least one of said brake lock means (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.
