A dolly comprising a chassis, a castor having a fork and a wheel rotatably mounted to the fork, and a fastener for fixing the fork of the castor to the chassis of the dolly. The fastener comprises a head which is shaped to the peripheral shape of the wheel of the castor.

A caster with horizontal braking includes a connecting base, a wheel rotatably connected to the connecting base, and a brake assembly including a movable plate slidably connected to the connecting base and a rotary plate. The movable plate is provided with a brake pad at an end and a first abutting plate with a limiting portion thereon, and is rotatably connected to the connecting base. A second abutting plate fitted with the first abutting plate is arranged on the rotary plate. When the rotary plate is rotated to cause the second abutting plate to push the first abutting plate to move backward, the brake pad moves backward to abut against the wheel, one end of the second abutting plate is abutted against the limiting portion, the force applied by the wheel to the brake pad opposites the force applied by the second abutting plate to the limiting portion.

A movable stand base, of the present invention, comprises: a base case; a wheel housing inserted from the lower part of the base case; a wheel module accommodated in the wheel housing; a rotation plate rotatably coupled to the base case; and a brake ring, which is positioned inside the wheel housing, rotates during rotation of the rotation plate and moves in the vertical direction, makes contact with a wheel of the wheel module during lowering of the brake ring so as to restrict rotation of the wheel, uses the wheel so as to facilitate movement, and can restrict rotation of the wheel so that stability can be increased during mounting.

Caster assemblies are disclosed herein. An example caster assembly includes a caster frame assembly including a caster frame, a caster mounting plate, and a brake arm; a pin having a first end and a second end opposite the first end, the second end to engage the brake arm; and a lever arm having a third end and a fourth end opposite the third end, the lever arm to pivot relative to the caster frame assembly between a first position and a second position, movement of the lever arm to the first position to cause the fourth end of the lever arm to actuate the pin in a first direction to move the brake arm to the engaged position to restrict rotation of the wheel.

A patient transport apparatus comprises a support structure and at least one caster assembly coupled to the structure to facilitate movement of the structure along a floor. Each caster assembly comprises a wheel, an actuator moveable between three actuator positions, a steer lock assembly moveable by the actuator between a steer and non-steer locked state, and a brake assembly movable by the actuator between a braked and unbraked state. The brake assembly includes a plunger, a retainer coupled to the plunger, a brake pad for sliding movement along the retainer, and a brake biasing element disposed between the plunger and the brake pad to urge the brake pad away from the plunger such that movement of the actuator to place the brake assembly in the braked state simultaneously brings the brake pad into engagement with the wheel and slides the brake pad along the retainer to compress the biasing element.

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.

A swivel castor arrangement for a piece of furniture comprises: a holder; a swivel castor including a wheel mounted rotatably about a first axis on a frame mounted rotatably about a second axis on the holder; and a U-shaped bracket having a web connecting two legs attached rotatably about a third axis. The bracket is pivotable about the third axis between first and second positions and is movable into the second position when the first and third axes are substantially parallel. The wheel is arranged in the second position between the bracket legs such that free rotation of the frame about the second axis is restricted, and the wheel in the first position is not arranged between the bracket legs such that free rotation of the frame about the second axis is possible. The bracket is pivotable by less than 90 to switch between the first and second positions.

A patient transport apparatus comprises a support structure and at least one caster assembly coupled to the structure to facilitate movement of the structure along a floor. Each caster assembly comprises a wheel, an actuator moveable between three actuator positions, a steer lock assembly moveable by the actuator between a steer and non-steer locked state, and a brake assembly movable by the actuator between a braked and unbraked state. The brake assembly includes a plunger, a retainer coupled to the plunger, a brake pad for sliding movement along the retainer, and a brake biasing element disposed between the plunger and the brake pad to urge the brake pad away from the plunger such that movement of the actuator to place the brake assembly in the braked state simultaneously brings the brake pad into engagement with the wheel and slides the brake pad along the retainer to compress the biasing element.

A caster with horizontal braking includes a connecting base, a wheel rotatably connected to the connecting base, and a brake assembly including a movable plate slidably connected to the connecting base and a rotary plate. The movable plate is provided with a brake pad at an end and a first abutting plate with a limiting portion thereon, and is rotatably connected to the connecting base. A second abutting plate fitted with the first abutting plate is arranged on the rotary plate. When the rotary plate is rotated to cause the second abutting plate to push the first abutting plate to move backward, the brake pad moves backward to abut against the wheel, one end of the second abutting plate is abutted against the limiting portion, the force applied by the wheel to the brake pad opposites the force applied by the second abutting plate to the limiting portion.
