A cart includes a first side board and a second side board. Each of the first and second side boards has first holes and second holes respectively defined in the upper and lower portions thereof. A first rod unit and a second rod unit are respectively connected to the first holes and the second holes of the first and second side boards. At least two shelves are movably mounted on the first and second rod units between the first and second side boards. A first wheel unit and a second wheel unit are respectively connected to the second holes at the front side and the rear side of the body so as to assemble the cart. The diameter of the second wheel unit is larger than that of the first wheel unit. The cart is light and suitable to move on an uneven surface.

Collapsible reusable carrying cases are provided in sizes varying from small food containers to large push cart bins on casters. The cases are assembled or disassembled from a joined flat space-saving configuration to a functioning case and vice-versa. All parts that make up a carrying case do not separate from the carrying case and no parts can be removed. The cases are formed from rigid plastic panels, and are assembled or disassembled without tools. The sides of the cases are erected progressively by hand by interlocking elements at the corners. The panels also disassemble progressively by being manually pulled apart. When folded into a flat storage or shipping configuration, the panels stay together, resisting unfolding by virtue of snaps which are either molded into the panels or bonded to them. The carrying cases are resistant to water, dirt, bacteria, molds, allergens, and inclement weather.

A stand assembly and method of converting a stand assembly from a moveable configuration to a stationary configuration is provided. The stand assembly includes a plurality of wheel assemblies slidably engaged with a plurality of respective trivets, each wheel assembly being moveable between a stowed configuration and a deployed configuration, thereby moving each trivet between a deployed configuration and a stowed configuration, respectively. When in their respective deployed configurations, a distal end of each trivet is engaged with the floor, thereby causing the stand assembly to be in the stationary configuration. When in their respective stowed configurations, the distal end of each trivet is positioned between two wheels of the wheel assembly such that the wheel assembly prevents the trivet from engaging with objects on the floor, thereby minimizing adjustments required to obtain desired ground clearance.

A portable surgical robot includes a surgical device and a cart. The surgical device is coupled to the cart. The cart includes a chassis, a mount coupled to the chassis, a carriage pivotally coupled to the mount, and a set of wheels. The carriage includes a first bracket positioned at a first lateral end of the carriage and a second bracket positioned at a second lateral end of the carriage. A first wheel of the set of wheels is coupled to the first bracket and a second wheel of the set of wheels is coupled to the second bracket. The carriage is configured to pivot relative to the mount to prevent at least one of (i) rocking of the portable surgical robot, (ii) fluttering of the first wheel, (iii) fluttering of the second wheel, and (iv) tipping of the portable surgical robot.

A portable surgical robot includes a surgical device and a cart. The surgical device is coupled to the cart. The cart includes a chassis, a frame member, a pair of wheels, and a steering mechanism. The chassis defines a longitudinal axis that extends a length of the cart. The frame member is coupled to the chassis of the cart. The pair of wheels are pivotably coupled to the frame member. The steering mechanism is coupled to the pair of wheels. The steering mechanism is configured to facilitate selectively pivoting the pair of wheels to steer the cart in a plurality of steering modes. The plurality of steering modes include at least one of a fore-and-aft steering mode, a turn-on-axis steering mode, and a lateral steering mode.

A support arrangement having an activation mechanism to control the movement of wheels is provided. The support arrangement includes a platform, a chassis attached to the platform, a pair of wheel assemblies movably coupled to the chassis, and the activation mechanism. The pair of wheel assemblies are operable between a first state and a second state. The activation mechanism includes a track having a first stable position and a second stable position spaced along a length of the track, and a pin configured to travel along the track. Wheels are in the first state when the pin is in the first stable position and are in the second state when the pin is in the second stable position.

Disclosed are a door supporting apparatus and method of using same. While a heavy door is loaded to the door supporting apparatus, the door supporting apparatus may be rotatable between horizontal and vertical orientations to enable safe handling of the heavy door for serving and/or repairs.

A cart includes a first side board and a second side board. Each of the first and second side boards has first holes and second holes respectively defined in the upper and lower portions thereof A first rod unit and a second rod unit are respectively connected to the first holes and the second holes of the first and second side boards. At least two shelves are movably mounted on the first and second rod units between the first and second side boards. A first wheel unit and a second wheel unit are respectively connected to the second holes at the front side and the rear side of the body so as to assemble the cart. The diameter of the second wheel unit is larger than that of the first wheel unit. The cart is light and suitable to move on an uneven surface.

A wheel assembly for an infant support apparatus includes a wheel mount, a wheel pivotally connected with the wheel mount about a pivot axis, and a brake member assembled with the wheel for movement between a braking state and a release state, the brake member when in the release state being rotatable with the wheel relative to the wheel mount, and the brake member when in the braking state engaging with the wheel mount to block rotation of the wheel relative to the wheel mount.

A cart provided with a brake assembly capable of synchronously braking two casters having a cart frame. Two front casters and two rear casters are symmetrically arranged at the bottom of the cart frame. A brake mechanism is arranged on the two rear casters and having a connecting tube, a pedal mounted on the connecting tube and two brake assemblies mounted at ends of the connecting tube respectively. Two ends of the connecting tube are connected to the two brake assemblies respectively. The pedal drives the connecting tube to rotate, and limit portions of the brake assemblies abut against limit pieces on the rear casters to bake the rear casters. The two rear casters can be braked synchronously, thus improving the braking efficiency of the cart in the moving process.
