A movable standing base for parasols, display boards, flagpoles and the like comprises a weight part having, firmly attached at the bottom side thereof, at least three, preferably four steering rollers, and it further comprises attachment elements for a parasol, for a display board, for a flagpole or for any other objects to be set up, and a plurality of preferably four lowerable blocking feet. In order to improve ease of handling without loss of stability, the blocking feet are connected to each other in the edge region of the weight part by two bridge girders arranged opposite to each other and a middle yoke and are anchored to the weight part in a substantially parallelogram shaped lowerable manner by two pivot levers. A tensioning lever is disposed resting on the middle yoke, and a pressure element leads to a blocking pedal at the upper side of the standing base.

A mobile surgical robotic cart assembly used for minimally invasive surgery includes a vertical column supporting a robotic arm thereon and a base portion having at least three casters adapted to allow the surgical robotic assembly to move. The surgical robotic cart assembly further includes an immobilization assembly coupled to the base portion, the immobilization assembly being configured to move between an unlocked position and a locked position. The surgical robotic cart assembly is mobile when the immobilization assembly is in the unlocked position and immobile when the when the immobilization assembly is in the locked position.

A shopping cart foot wheel capable of warning the abrasion status of the braking block comprising an escalator wheel assembly; the escalator wheel assembly comprises an escalator wheel core and escalator wheel discs; the escalator wheel discs are located on the two sides of the escalator wheel core, and are coaxially arranged with the escalator wheel core; the escalator wheel assembly further comprises an escalator wheel support, wherein the escalator wheel support is provided with an escalator wheel axle; locking nuts are simultaneously arranged at the two ends of the escalator wheel axle; the escalator wheel core is connected with the escalator wheel axle in a sleeved mode.

Included is a stabilizer wheel assembly that may assist in stabilizing a medical device during a medical procedure. A medical device may comprise a body; and a plurality of stabilizer wheel assemblies coupled to the body, wherein the stabilizer wheel assemblies each comprise a motor assembly and a stabilization leg, wherein the motor assembly is configured to drive the stabilization leg onto a contact surface to stabilize the body.

A patient care bed including a caster locking mechanism having a foot movable between retracted and extended positions, a lock bar movable from an unlocked to a locked position, a release bar movable from an initial to a release position, and a lock and release assembly. The lock and release assembly includes a guide plate defining a slot, a rocker coupled to the lock bar and including a protrusion slidable within the slot, and a release member coupled to the release bar and including a protrusion slidable within the slot. Moving the lock bar to the locked position slides the protrusion of the rocker through the slot to extend the foot. Moving the release bar to the release position urges the protrusion of the release member through the and into contact with the protrusion of the rocker to urge the protrusion of the rocker back, thereby retracting the foot.

An adjustable caster assembly includes a body having a top surface and a base, and an opening within the base. A wheel is connected to the body, where the wheel is configured to extend beyond the base of the body to engage a supporting surface. A foot is positioned within the opening in the base and configured to move between an expanded position and a contracted position. The foot may be actuated by an actuation shaft that engages a gear. The actuation shaft may be movable between an engaged position and a disengaged position.

A mobile surgical robotic cart assembly used for minimally invasive surgery includes a vertical column supporting a robotic arm thereon and a base portion having at least three casters adapted to allow the surgical robotic assembly to move. The surgical robotic cart assembly further includes an immobilization assembly coupled to the base portion, the immobilization assembly being configured to move between an unlocked position and a locked position. The surgical robotic cart assembly is mobile when the immobilization assembly is in the unlocked position and immobile when the when the immobilization assembly is in the locked position.

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.

Included is a stabilizer wheel assembly that may assist in stabilizing a medical device during a medical procedure. A medical device may comprise a body; and a plurality of stabilizer wheel assemblies coupled to the body, wherein the stabilizer wheel assemblies each comprise a motor assembly and a stabilization leg, wherein the motor assembly is configured to drive the stabilization leg onto a contact surface to stabilize the body.

A tipping prevention unit that prevents tipping of an image forming apparatus includes shafts holding a wheel of the image forming apparatus, a shaft that abuts the image forming apparatus at a position higher than the shafts, and a shaft that contacts a floor surface on which the image forming apparatus is placed at a position further protruding to the outside of the image forming apparatus than the wheel of the image forming apparatus.
