A galley cart restraint mechanism is provided. The galley cart restraint mechanism including a base portion, a post portion coupled to the base portion, and a foot portion coupled to the post portion. At least the foot portion is configured to engage with a floor track to prevent movement of the galley cart in at least a first direction.

An MRI compatible stretcher has a plurality of non-magnetically susceptible and electrically conductive metal members in physically overlapping sections, each having electrically non-conductive spacers separating the overlapping sections to prevent electrical conductivity there between. The insulators break electrical conductivity and thereby prevent the formation of large and continuous metal current loops, while the overlap ensures continuous metal strength and integrity. In particular embodiments, flanges terminate longitudinally extensive metal members, and the electrically non-conductive spacers separate the flanges from adjacent metal members. Fasteners secure the flanges, spacers and adjacent metal members together.

Improvements in a caster wheel tilt bar is disclosed. The caster wheel tilt bar is installable and removeable on a caster and is secured over one side of the caster frame and utilizes the tapered portion of the wheel frame. When the cart frame is rotated the tilt bar comes in contact with the ground. Further rotation lifts the wheel above the ground. The tilt bar can be configured in an arc or can be configured with defined angular steps. The angular steps are generally calculated to create a balance point where the cart can hold with limited rocking. The caster wheel tilt bar can also be painted or powder coated to match the color of the pre-existing caster wheel. Because the rod and shoe can be different components, the shoe or rod can be adjusted to accommodate different casters and/or wheel diameters.

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 actuation assembly includes a torque input element, a torque output element, and a transfer linkage assembly comprising a connector assembly which connects the input element to the output element. The connector assembly includes a first connector having a proximate end and a connector portion. The proximate end of the first connector is the end closer to either the input element or the output element, and the connector portion is further from that same element. The connector assembly also includes a second connector having a proximate end closer to the other of the input element and the output element. The connnector portion is further from that same element. The connector portions are selectively joinable to either permit or resist relative longitudinal translation of the first and second connectors. One example application for the actuation assembly is as an actuation assembly for a braking system on a hospital bed.

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.

The present disclosure provides a gantry for an X-ray system. The gantry may include a base section, a lifting section, and a swing section. The base section may be configured to move. A first end of the lifting section may be connected to the base section. A first end of the swing section may be rotatably connected to a second end of the lifting section. A radiation assembly may be disposed on a second end of the swing section.

An ultrasound diagnostic apparatus includes: a plurality of drive casters; a plurality of lock mechanisms that are respectively provided in the plurality of drive casters, each of the plurality of lock mechanisms locking movement of a corresponding drive caster; and an indicator that presents whether the lock mechanism is in a locked state in which the movement of the drive caster is locked or in a released state in which the movement of the drive caster is allowed.
