Abstract
A quick connect-disconnect brake hub lock system is disclosed. The locking mechanism is attached to camber tubes of varying degrees of 0° to 12° with wheels that move in and out from the centerline of the wheelchair. Such system of locking must be quick disconnected and reconnected to adapt to the various camber tubes that have varying degrees of angles. Not only do the camber tubes adjust the caster and camber of the wheels, but are adjusted for wheelbase width The brake hub locking mechanism must move with these elements and have the capacity to lock the wheels at whatever position the wheels are in. The sliding mechanism in the handle is completely enclosed to prohibit dirt, which wears such elements quickly. The rotary cam mechanism sliding against the rectangular slider provides the means of pulling the cables straight thus eliminating breaking and thereby locking or unlocking the wheels of the wheelchair.
