Wheelchair brake
A wheelchair brake includes a pressing lever having a free end which pivots about a first axis to make braking contact with a wheelchair wheel. The pressing lever is normally urged into a neutral position away from the wheel by an elastic, spring-like member, such as a rubber band or O-ring. A first...

| description | A wheelchair brake includes a pressing lever having a free end which pivots about a first axis to make braking contact with a wheelchair wheel. The pressing lever is normally urged into a neutral position away from the wheel by an elastic, spring-like member, such as a rubber band or O-ring. A first brake lever for operating the brake by a companion is connected via a Bowden wire to the free end of the pressing lever, so that depression of the first brake lever causes the pressing lever to pivot into braking contact with the wheel. A manually releasable safety catch automatically engages the first braking lever when the lever is depressed, thereby locking the lever in its braking position. A second brake lever is also provided for use by the wheelchair user. The second lever pivots about a second axis causing a pressure part to bear against the same pressing lever causing a braking contact with the wheel. Further pivoting of the second lever also causes the mechanism to lock in a braking position. |
