A caster assembly for a wheelchair comprises a stem having a frame clamp at a first end and a fork clamp at a second end, the frame clamp configured to form a frame joint with at least one rotational degree of freedom with a frame portion of the wheelchair, a tightening of the frame clamp securing the stem to the frame portion, the frame joint having a frame rotational axis. A fork unit has a fork portion and a caster rotatably supported by the fork portion, the fork unit having swivel mechanism, and a joint portion forming a rotational joint with the fork clamp of the stem, a tightening of the fork clamp blocking rotation of the rotational joint, the rotational joint having a fork rotational axis. A vector of the fork rotational axis is normal to a fork rotational plane in which the fork rotates relative to the stem, and further wherein the frame rotational axis is not parallel to the fork rotational plane.

An anti-rolling wheel includes: a ring-shaped main wheel; an inner frame positioned inside the main wheel, wherein the inner frame comprising at least two auxiliary wheels that come into contact with an inner surface of the main wheel and rotate when the main wheel is driven; and a sliding block provided to be movable under the guide of the inner frame.

A patient support apparatus for traversing objects supported on ground surfaces. The patient support apparatus comprises a patient support deck, and a base to support the patient support deck from the ground surface. At pair of caster wheel assemblies spaced from each other are coupled to the base for pivoting movement about respective pivot axes cooperating to define a reference plane. A frame guard coupled to the base defines first and second ramp surfaces each disposed at an angle relative to the reference plane. The first ramp surface is arranged to engage objects before they contact one or more of the caster wheels when the patient support apparatus moves in a first direction. The second ramp surface is arranged to engage objects before they contact one or more of the caster wheels when the patient support apparatus moves in an opposite, second direction.

The present disclosure relates to a caster wheel assembly (1), comprising: a caster housing (3) provided with an axial channel, a spindle shaft (7) configured to be received by the channel of the caster housing (3), which spindle shaft (7) is inclined relative to the vertical plane when mounted in the caster housing (3) and the caster wheel assembly (1) is in use resting on a horizontal support, the caster housing (3) and the spindle shaft (7) being configured to rotate freely relative to each other, a caster wheel fork (9) having a wheel axle (11) configured to be arranged offset relative to a central axis of the spindle shaft (7), to provide a trail functionality, and a height adjustment mechanism (6) configured to adjust an axial position of the spindle shaft (7) relative to the caster housing (3) based on a rotational position of the spindle shaft (7) in relation to the caster housing (3).

An electric walking assisting vehicle configured such that in accordance with operating amounts acting on an operation part, driving of driving motors is controlled and includes an inclination detector which detects inclination of a vehicle body in a forward-backward direction, and on flat land where inclination is less than a threshold, with an operation origin of the operation part as a center, the driving motors are controlled to generate torque in a forward direction by operation of pushing the operation part forward and to generate torque in a backward direction by operation of pulling the operation part backward, on an uphill road on which the inclination is the threshold value or more, the operation origin is shifted to an pulling operation side, and on a downhill road on which the inclination is the threshold value or more, the operation origin is shifted to a pushing operation side.

A system comprising a movable device including front wheels and rear wheels configured to swivel and roll, a braking system configured to lock the front wheels and the rear wheels to keep the front wheels and the rear wheels from rolling, a directionally locking system configured to keep the rear wheels from swiveling, first and second rear pedals configured to control the front and rear wheels to be in one of a locked state, a directionally locked state, or a released state, and first and second front pedals configured to control the front and rear wheels to be in one of a locked state or a released state.

Cable protector devices, assemblies, and systems. The cable protection system may include a moveable system with wheels for moving the moveable system across a floor and a cable pusher attached to each of the wheels. Each cable pusher may include a frame with a pair of deflector legs configured to be positioned in front of and behind each wheel in close proximity to the floor. The cable pusher may be magnetically secured to the wheel, and the deflector legs may magnetically connect to the frame. As the wheels spin or rotate, the frame and deflector legs remain stationary, thereby pushing obstacles out of the way.

A caster for equipment, furniture and medical equipment, the caster including a support arm that includes a base portion and a top portion and receives an attachment bolt wherein the base portion supports a wheel axle that supports at least one wheel; a direction fixing device; and a movable blocking element configured to lock the direction fixing device, wherein the moveable blocking element is in direct or indirect friction contact with the wheel so that a friction force that is caused by the friction contact causes a locking of the direction fixing device and a direction fixing of the caster in a first direction when the caster moves in the first direction.

Methods and systems are provided for controlling movement of a mobile medical device drive platform. In one example, a mobile platform includes a chassis configured to house one or more medical devices, an omnidirectional wheel system including an omnidirectional wheel coupled to the chassis, a battery housed in the chassis, the battery configured to supply power to drive the omnidirectional wheel system and/or supply power to operate the one or more medical devices, and a battery charging system housed in the chassis, where the battery charging system is configured to facilitate wired and/or wireless charging of the battery.

A caster for equipment, furniture and medical equipment, the caster including a support arm that includes a base portion and a top portion and receives an attachment bolt wherein the base portion supports a wheel axle that supports at least one wheel; a direction fixing device; and a movable blocking element configured to lock the direction fixing device, wherein the moveable blocking element is in direct or indirect friction contact with the wheel so that a friction force that is caused by the friction contact causes a locking of the direction fixing device and a direction fixing of the caster in a first direction when the caster moves in the first direction.
