A patient transport apparatus includes a base, a patient support deck, a plurality of wheels, a plurality of brakes, and an electro-mechanical braking system. The electro-mechanical braking system includes a linkage, a manual actuator, and an electrical braking assembly. The linkage is operatively coupled to the brakes to place the brakes in a braked state, a released state, or other state. The manual actuator moves the linkage manually to place the brakes in one of the states. The electrical braking assembly includes an actuator assembly that moves the linkage with electrical power to place the brakes in one of the states.

The present disclosure relates to caster wheels having a skirt, specifically a skirt which fits over one side of the wheel only, and thus does not interfere with the actuation of a caster wheel locking mechanism.

A caster yoke for use in the manufacture of a set of wheeled caster assemblies wherein each caster assembly of the set of caster assemblies is capable of having unique functional capabilities relative to each other caster assembly of the set arising from different combinations of caster components (selected from a set of pre-determined of caster components) being mountable on each respective caster yoke of the set of wheeled caster assemblies. To this end, the caster yoke is provided with all of the mounting features necessary to selectively mount all of the respective caster components of the pre-determined set on the caster yoke, such that the same form of caster yoke may be used without modification as a mounting frame to create a set of caster assemblies having different functionalities, significantly reducing design, production and inventory costs for the set of caster assemblies.

A pressured braking wheel includes a wheel seat, an axle sleeve, a first wheel rim and a second wheel rim. The wheel seat has an accommodation space and a braking tenon. The axle sleeve is arranged in the accommodation space and sleeves a wheel axle. Inner sides of the first wheel rim and the second wheel rim are respectively annularly provided with first tenon grooves and second tenon grooves. The first wheel rim and the second wheel rim pivotally connect with the axle sleeve through the wheel axle. The first tenon groove and the second tenon groove are arranged under the braking tenon. When the wheel seat is pressed down, the wheel seat inserts the braking tenon into the first tenon groove and the second tenon groove, so as to prevent the first wheel rim and the second wheel rim from rotating with respect to the wheel seat.

A brake mechanism for mobile currency vaults includes a braking gear coupled to a vault wheel to govern rotational movement of the wheel. An interference tab is biased to an interference fit between the gear's teeth to stop rotation of the wheel. Disengaging the gear is controlled near the handles of the vault, which also provide steering control, so that users must actively disengage the interference tab to allow the wheel to rotate. The brake mechanism also has a brake release for locking in a disengaged or engaged position. The brake release spans the mobile currency vault from a front wheel to a rear handle. The brake release also has a control, preferably at a rear end of the vault, requiring activation by a key and an indicator pusher.

A multi-pedal-controlled caster and a method for using the caster are provided. The multi-pedal-controlled caster includes a main body support, a connecting rod, an orientation mechanism, a braking mechanism, a reset mechanism, a first inner tooth member, a second inner tooth member, a pair of wheel members and three elastic members, where the main body support is relatively rotatable and is combined with the connecting rod, and the first inner tooth member and the second inner tooth member are fixedly mounted on the connecting rod. A multifunctional pedal is treaded to push a first warping plate to make the first warping plate clamped into a first recess portion of the first inner tooth member, so that the caster can run in an orientated manner; and the multifunctional pedal is treaded again to push an auxiliary braking member.

A cart stabilization system and rolling cart elements for robotic surgery and other medical instrumentation are disclosed. The cart stabilization system includes a base and lifting caster systems coupled to a bottom portion of the base. Each lifting caster system includes a rolling element, a swivel foot assembly moveably coupled to the rolling element; and a hydraulic mounting base coupled to a portion of the swivel foot assembly. Methods of assembling a lifting caster system and for using a cart stabilization system are also disclosed.

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.

The invention relates to a roller (1), preferably comprising two wheels (2) and a locking device, an activating part (10) acting on the locking device for releasing or locking, and the activating part (10) being movable by a drive, a movement of a transmission part (7) that is generated by the drive being transmitted via spring force to the activating part (10) for moving same, and a spring (8) being supported on the transmission part. In order to provide a roller that allows an advantageous constructional design, it is proposed that a support region is formed for the spring (8) and/or the spring (9) and/or the compression spring (44) on the activating part (10), through which region the transmission part (7) can pass.

A swivel castor, having a housing which can be pivoted into a rolling direction via pivot means and two wheels rotatably mounted on the housing on a horizontal wheel axle, wherein the pivot means are arranged in front of the wheel axle, contrary to the rolling direction, and having a braking device designed to be adjustable between a braking position, in which the braking device exerts a braking force on at least one wheel, and a free-rolling position, in which the braking device releases the wheels. A brake pedal generating the braking force is pivotably mounted on the housing via a pedal axle, which extends parallel to the wheel axle and arranged between the wheels, and, in the braking position, at least one brake shoe arranged on the brake pedal exerts a braking force parallel to the wheel axle directly on one side of at least one wheel.
