A patient transport apparatus comprises a support structure. The support structure comprises a base, a frame, and a patient support surface to support a patient. The patient transport apparatus also includes a first and a second caster assembly respectively coupled to the support structure to facilitate movement of the support structure along a floor surface, with the first caster assembly comprising a first brake assembly and the second caster assembly comprising a second brake assembly. The patient transport apparatus also includes an actuator assembly operatively coupling the first and second brake assemblies, with the actuator assembly comprising a first and second actuator respectively operatively coupled to the first and second brake assemblies. The actuator assembly further comprises a cable assembly interconnecting the first and second actuator that places the operatively coupled first and second brake assemblies in the braked state or the unbraked state.

The invention relates to a castor with at least one wheel (16, 18), a housing (10) carrying the at least one wheel (16, 18), and a runner pin (14) which is arranged so as to be movable to a limited extent in a substantially vertically oriented housing opening (12) and which serves to connect the castor to an object, wherein the housing (10) accommodates a brake device which frees the at least one wheel (16, 18) in a state in which the castor is loaded by a weight via the runner pin (14) and which acts with a braking effect on the at least one wheel (16, 18) in a state when not loaded by a weight.

An operating shaft rises and falls by abutting against a cam surface of a cam rotatably built into the upper part of a stem. A swivel-preventing plate part is fixed to the lower end of the operating shaft. An engagement member is fixed to a support yoke and regulates the swiveling by engaging with the swivel-preventing plate part. A brake shoe part is fixed to the lower part of the swivel-preventing plate part and brakes by abutting against a treat surface of a wheel when the operating shaft falls. A link cam causes a link cam to pivot and causes a brake plate to rise and fall by connected to the brake shoe part. A protruding part for braking, by displacement of the brake plate, is capable of engaging with and disengaging from an annular engagement receiving part formed in the inner periphery of the wheel.

A chair lock system for inhibiting a chair from rolling when the chair is occupied includes a chair. A plurality of wheels is rotatably coupled to the chair and each of the wheels may roll along a support surface. Each of the wheels is positioned on the base. A locking unit is coupled to the chair and the locking unit inhibits the wheels from rolling along the support surface when the chair is sat upon.

According to a first aspect of the present disclosure, there is provided a wheeled transport device featuring at least one castor which has a wheel and a brake system which has a contact member with one opening which is defined by an edge. The contact member is configured to be manipulated between an applied state, where the edge is in contact with the wheel, and a released state where the edge is not in contact with the wheel.

A walking aid device includes a support body inclusive of a plurality of support elements extending toward the ground. Each support element is coupled to a caster and a brake unit. Each brake unit has a clutching surface. The clutching surface controllably clutches a wheel of the caster or the ground to thereby generate friction for stopping the walking aid device.

Art operating shall rises and fails by abutting against a cam surface of a cam rotatably built into the upper part of a stem. A swivel-preventing plate part is fixed to the lower end of the operating shaft. An engagement member is fixed to a support yoke and regulates the swiveling by engaging with the swivel-preventing plate part. A brake shoe part is fixed to the lower part of the swivel-preventing plate pail and brakes by abutting against a treat surface of a wheel when the operating shaft falls. A link cam causes a link cam to pivot and causes a brake plate to rise and fall by connected to the brake shoe part. A protruding part for braking, by displacement of the brake plate, is capable of engaging with and disengaging from an annular engagement receiving part formed in the inner periphery of the wheel.

A chair lock system for inhibiting a chair from rolling when the chair is occupied includes a chair. A plurality of wheels is rotatably coupled to the chair and each of the wheels may roll along a support surface. Each of the wheels is positioned on the base. A locking unit is coupled to the chair and the locking unit inhibits the wheels from rolling along the support surface when the chair is sat upon.

A castor for movable objects, in particular a bed castor, at least includes a running wheel, a fork receiving the same one, a guiding tube which is swiveling with respect to the fork via at least one bearing, a lock provided on the side of the fork as well as a brake system which is rotation-proof and can be operatively connected to the running wheel. The brake system includes an essentially cylindrical fixing element which is profiled on one side and can be operatively connected to a polygonal safety element on the side of the fork for forming the rotation lock.

A walking aid device includes a support body inclusive of a plurality of support elements extending toward the ground. Each support element is coupled to a caster and a brake unit. Each brake unit has a clutching surface. The clutching surface controllably clutches a wheel of the caster or the ground to thereby generate friction for stopping the walking aid device.
