An electrical brake mechanism for a caster can reliably brake a caster. A switch is mounted on a target to which a caster is attached and outputting an instruction signal to a brake device, a detector is provided on a rotating shaft of the cam and arranged in correspondence with each of positions of a plurality of cam surfaces, a sensor is provided for detecting abutment between each of the cam surfaces and an operation shaft by the detector, a motor is provided for rotating by an input of the switch and for stopping if the sensor detects the position of the predetermined cam surface, and a gear train is provided for transmitting rotation of the motor to the rotating shaft of the cam.

A device for mounting an aircraft tail wheel includes a support plate having, on the one hand, an articulation shaft with an arm and, on the other hand, an articulation shaft with a fork receiving the freely rotating tail wheel, while the articulation shaft of the plate is positioned near a rotation shaft of the tail wheel.

A lockable swivelable caster provides for an interaction between a centering element and a locking element to pivotally urge the locking element into a locking notch of the centering element such that the locking element is captured by the locking notch to prevent swiveling of the caster wheel.

An apparatus is for locking a caster wheel in a steering position about a steering axis. The apparatus comprises a base member; a lever arm; and an engagement member. The lever arm is movable with respect to the base member into and between an engaged position in which the engagement member locks the caster wheel in the steering position and a disengaged position in which the caster is steerable out of the steering position.

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.

The invention relates to a caster for movable objects, and more particularly a bed caster, and at least comprises: a running wheel; a fork receiving said running wheel; a guide tube which is designed to be swivelable relative to the fork via at least one bearing; locking means provided on the fork side; and a braking system which can be brought into operative connection with the running wheel and is designed to block rotation of the wheels, characterised in that the braking system includes a brake shoe, a brake spindle, a guide pin and a cup-shaped guide element, wherein the brake spindle has groove-shaped guides, the cup-shaped guide element is provided with projections, and the projections can be brought into operative connection with the guides of the brake spindle in order to form the anti-rotation means.

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.

An arrangement for limiting rotation, the arrangement including a base structure; a drive member rotatable relative to the base structure and having a drive feature; a stopping member having at least one driven feature, wherein the stopping member is arranged to be intermittently driven relative to the base structure between a plurality of discrete positions by a continuous rotation of the drive member and by cooperation between the drive feature and at least one driven feature, wherein the stopping member in a first end discrete position is arranged to limit rotation of the drive member in a first end position of a rotation range of the drive member; and a holding mechanism arranged to hold the stopping member in each discrete position, the holding mechanism being at least partly provided in the base structure.

A mobile cart such as a jogging stroller includes a frame and a swivel caster coupled to the frame. The swivel caster is arranged to swivel relative to the frame about a swivel axis.

A line striper comprises a sprayer secured to a frame, and a guided wheel assembly rotatably mounted to the frame. The guided wheel assembly includes an adjustment disk with screw notches along its outer diameter, an alignment plate coaxially surrounding and abutting the adjustment disk, alignment screws threaded through the alignment plate to engage screw notches on the adjustment disk, and an antirotation lock. The screws set a rotational alignment of the alignment plate relative to the adjustment disk, and the adjustment disk is coupled via a spindle axle to a guide wheel. The antirotation lock engages a locking feature on the alignment plate, thereby fixing the orientation of the guide wheel relative to the wheeled frame at an angle determined by the rotational alignment.
