ABSTRACT:
An incline climbing brake for wheelchairs in which each of the large wheels on a wheelchair is provided with a selective ratchet assembly which enables the wheels to rotate in only one direction thereby enabling a wheelchair occupant to safely maneuver a wheelchair in order to roll it up an incline in either a forward or rearward direction. The ratchet assembly includes a ratchet gear non-rotatably secured to the wheelchair at the center of rotation of the wheel by a bracket attached to a frame member of the wheelchair and connected to the axle bolt in a manner to prevent the axle bolt from rotating in relation to the wheelchair frame member. Manually operated direction controlling pawls are engageable with the stationary ratchet wheel. Expandable arms mount the ratchet assembly from the rim of the large wheel of a wheelchair with the ratchet assembly enabling rotation of the wheel in one direction only with the pawls enabling reversal of the one-way direction of rotation of the large wheelchair wheel.
