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. 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 caster has a yoke portion and wheel forks pivotally connected to the yoke portion at a pivot connection. The pivot connection defines a pivot axis. A wheel is rotatably connected to the wheel fork at a wheel axis. A brake lever is operatively connected to the pivot connection to pivot about the pivot axis. The brake lever moves a brake pad between an engaged position and a disengaged position as the brake lever is pivoted about the pivot axis. In the engaged position, brake pad is pressed against the wheel with a cam operatively connected to the brake lever, and wherein the disengaged position, the cam cooperates with the brake pad in a manner such that the brake pad releases from the wheel.

An exercise machine has a mobile base and an upright support extending upwards from the mobile base. An upper support assembly extends forward from an upper portion of the upright support and an exercise device is suspended from the upper support assembly at a location spaced forward from the upright support. The exercise machine may include a compact and safe counterbalancing gas spring mechanism that tends to move the exercise device away from the exerciser, and that requires a force to be applied to move an exercise device down towards the exerciser. The exercise machine may include an exercise device that is rotatable along a vertical axis, and may be coupled to an adjustable monitor for a wide range of uses. The exercise machine may be used by a exerciser lying supine, sitting in a chair or wheelchair, or standing in front of or adjacent the exercise machine.

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 caster device for a pipe leg includes a caster unit, a mounting unit, and a braking unit. The caster unit includes a wheel seat subunit, a caster subunit that is rotatably connected to a bottom end of the wheel seat subunit, and a protection subunit that is located between the wheel seat subunit and the caster subunit. The mounting unit is mounted to the wheel seat subunit and is adapted to be mounted to the pipe leg. The braking unit extends through the protection subunit and the wheel seat subunit into the mounting unit, and is movable in an up-down direction between a braking position, in which the braking unit projects out of the protection subunit and is in contact with the caster subunit so that the caster subunit is refrained from rotating, and an initial position, in which the braking unit is spaced apart from the caster subunit.

A radiographic imaging apparatus in which a radiation source support unit supports a radiation source is adapted to be capable of being quickly carried to a use position in a small radius. A radiographic imaging apparatus includes a leg unit that includes three or more wheel units and is capable of traveling on an apparatus-placement surface by using wheels, a body unit that is held on the leg unit, an arm unit as a radiation source support unit that is connected to the body unit, a radiation source that is mounted on the arm unit, a battery that is received in the body unit and drives the radiation source, and a circuit that is received in the body unit and relates to the drive of the radiation source. The wheel unit is formed of a revolving caster.

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.

A caster assembly having a top cap configured to engage with a structure, a caster leg configured to pivotally engage with the top cap, such that the caster leg selectively pivots about a pivot axis, and a pair of sinusoidal wheels configured to be rotationally engaged with the caster leg, the sinusoidal wheels being configured to rotate about a wheel rotational axis and swivel with the caster leg as a required when the structure is moved. An angled member of the caster leg may be configured to engage with the sinusoidal wheels such that the wheel rotational axis is not intersected by the pivot axis. An offset angle formed between the angled member and a vertical member of the caster leg, when used in conjunction with the disclosed sinusoidal wheels, is configured to ease structure movement by minimizing resistances exerted on the sinusoidal wheels during rolling and caster leg pivoting.
