A work vehicle includes a vehicle frame, a rotating connection unit provided in the vehicle frame, and a caster assembly connected to the rotating connection unit. The rotating connection unit includes a housing sleeve, a swivel post, a first bearing and a second bearing supporting the swivel post to be rotatable within the housing sleeve, and a rotation stopper disposed between the swivel post and the housing sleeve to stop rotation of the swivel post. The caster assembly includes a caster wheel, and a caster bracket connected to the swivel post to rotatably support the caster wheel.

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.

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 roller assembly comprises a housing having an outer surface attached thereto, and a braking arrangement positioned at least partially within the housing. The braking arrangement is configured to increase resistance to rotation of the housing proportionally to a load applied against the outer surface.

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.

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 shopping cart wheel includes a braking apparatus, and electronics that control the braking apparatus in response to wireless signals. The wireless signals include low frequency electromagnetic signals within a low frequency band and high frequency signals within a high frequency band. The braking apparatus includes a moveable interposer and an interposer controller where the moveable interposer is moved between braking and non-breaking positions at least partially with magnetic force.

An automatic speed reducing wheel includes a wheel unit and a speed reducing unit. The wheel unit includes a wheel seat, a wheel axle passing through the wheel seat, and a roller rotating about the wheel axle. A plurality of blockers is disposed on one side of the wheel frame in adjacent to an edge thereof in a radiation shape arrangement. The blockers rotate along with the roller. The speed reducing unit includes a fixing seat and a sliding member. The fixing seat is on one side of the roller and includes a sliding bore. The sliding member is slidably disposed in the sliding bore and includes an elastic portion having a blocking portion. When the roller moves downhill, the blocking portion of the sliding member protrudes out of an outer side of the sliding bore to interrupt a rotation route of the blockers, achieving a speed reducing effect.

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.
