Abstract
A brake system for use with a wheeled device, such as a wheeled person transportation device, such as a wheelchair. The brake system comprises a handle comprising a first portion and a second portion, wherein the first portion is moveably coupled to the second portion; a carrier comprising an internal cavity; a brake actuator for actuating a brake, the brake actuator being arranged within the internal cavity; brake actuator biasing means for applying a biasing force to the brake actuator for biasing the brake actuator to a brake-engaged position; and force-transfer means coupled to the first portion and to the brake actuator such that movement of the first portion towards the second portion causes the brake actuator to move along the internal cavity of the carrier against the biasing force to a brake-disengaged position.
Claims22
A brake system for use with a wheeled device, the brake system comprising:
- a handle comprising a first portion and a second portion, wherein the first portion is moveably coupled to the second portion;
- a carrier comprising an internal cavity;
- a brake actuator for actuating a brake, the brake actuator being arranged within the internal cavity;
- brake actuator biasing means for applying a biasing force to the brake actuator for biasing the brake actuator to a brake-engaged position;
- and
- force-transfer means coupled to the first portion and to the brake actuator such that movement of the first portion towards the second portion causes the brake actuator to move along the internal cavity of the carrier against the biasing force to a brake-disengaged position;
- wherein the first portion of the handle is rotatably coupled to the second portion, wherein the brake system comprises a rotation limiter for limiting the extent to which the first portion of the handle is rotatable away from the second portion, the rotation limiter being configured to be rotatable independently of the first portion of the handle and the rotation limiter comprising a stop configured to abut against a portion of the handle for limiting the extent of rotation of the first portion, the rotation limiter comprising locking means for rotationally locking the rotation limiter to the first portion of the handle.
A brake system for use with a wheeled device, the brake system comprising:
- a handle comprising a first portion and a second portion, wherein the first portion is moveably coupled to the second portion;
- the first portion comprising brake cable receiving means for receiving a first end of a brake cable for pulling on the first end of the brake cable;
- a brake actuator for actuating a brake;
- brake actuator biasing means configured to apply a biasing force to the brake actuator for biasing the brake actuator to a brake-engaged position;
- the brake actuator comprising brake cable receiving means for receiving a second end of the brake cable for pulling on the second end of the brake cable;
- the brake actuator being configured such that, when a first end of a brake cable is received in the brake cable receiving means of the first portion and a second end of the brake cable is received in the brake cable receiving means of the brake actuator, movement of the first portion towards the second portion causes the brake actuator to move against the biasing force to a brake-disengaged position;
- and
- wherein the brake system comprises a rotation limiter for limiting the extent to which the first portion of the handle is rotatable away from the second portion, the rotation limiter being configured to be rotatable independently of the first portion of the handle and the rotation limiter comprising a stop configured to abut against a portion of the handle for limiting the extent of rotation of the first portion, the rotation limiter comprising locking means for rotationally locking the rotation limiter to the first portion of the handle.
