A collapsible dolly assembly includes a pair of frames that are each selectively urged between a deployed position and a collapsed position. A pair of rear wheels is rotatably coupled to the frame to roll along a support surface. A pair of front wheels is rotatably coupled to the frame to roll along the support surface. A dolly is hingedly coupled to the frame to support an object thereby facilitating the object to be transported along the support surface. A pair of skid units is movably coupled to an associated one of the frames. Each of the skid units is selectively positioned in a deployed position. In this way each of the skid units frictionally engages a staircase thereby facilitating the object to be urged upwardly and downwardly along the staircase. A braking unit is movably coupled to the frame to selectively engage the staircase when the skid unit is positioned in the deployed position. Thus, the braking unit retains the object at a selected point along the staircase.

A wheeled cart includes a collapsible basket assembly configured to transport a variety of objects placed within. A brake lever arm is pivotably attached to the basket assembly and pivotable about a brake lever arm axis. A brake lever arm distal end is engaged by a user's foot to move between a released position and a braked position. The brake lever arm includes a brake feature. An inside face of a wheel includes a plurality of stops radially disposed about its axis. In the braked position the brake feature is configured to be positioned between at least two of the plurality of stops of the respective rear wheel thereby preventing rotation of the wheel. In the released position the brake feature is configured to be positioned outside the plurality of stops thereby allowing rotation of the wheel.

The present device provides a modular utility cart having configurable storage features which provide secure transportation for both large and small items. The basic cart construction includes a bottom platform having casters connected to the underside thereof, a top platform positioned above the bottom platform by four corner posts. The top and bottom platforms, as well as the corner posts, include various structural features which provide the modularity to the utility cart. The supports include notches and pockets that allow for removable bins to be positioned along the supports, as well as supports for shelving of various sizes. The top platform has an integrated tool rail configured to support and suspend items such as hand tools, ladder racks, bins, and additionally includes an adjustable height handle.

A mobility apparatus having: a base having casters; a handle assembly pivotally attached to the base; a locking mechanism operable to place the handle assembly into a plurality of positions corresponding to an operating mode of the apparatus, and maintain the handle assembly in one of the plurality of positions; an actuating mechanism coupled to the locking mechanism to actuate the locking mechanism; and wherein the locking mechanism comprises: a hub fixedly secured to the base; a hub ring rotatably secured within the hub and comprising attachment means for the handle assembly; a gas spring mechanism coupled to the hub ring to provide a mechanical advantage to assist an operator in lifting a patient; a breaking mechanism for the casters, wherein the breaking mechanism is operable to lock and unlock the casters simultaneously.

A cart has a folded configuration and a deployed configuration. The cart includes two side frames arranged opposite to each other; and a plurality of support members connected between the two side frames. Each side frame includes a vertical synchronization rod with a front foot assembly and a rear foot assembly arranged on two sides of the vertical synchronization rod. The front foot assembly includes a front foot rod with an upper front oscillating rod and a lower front oscillating rod hinged between the vertical synchronization rod and the front foot rod. A bottom of the front foot rod is hinged to a front wheel. The rear foot assembly includes a rear foot rod with an upper rear oscillating rod and a lower rear oscillating rod hinged between the vertical synchronization rod and the rear foot rod. A bottom of the rear foot rod is hinged to a rear wheel.

The present disclosure provides a brake mechanism of a cart, a brake mechanism, a pedal structure, a drive member of a wheel structure, and a cart, wherein the drive member is arranged in the brake mechanism to be movable, wherein the drive member has a guiding side face, and the guiding side face is provided with a guiding slot including a stop slot; wherein the brake mechanism is also provided with a braking member, a stop end of the braking member is arranged to move in the guiding slot; wherein the drive member is provided with an anti-damage device, and the anti-damage device is arranged such that when a user tends to move the drive member in an incorrect direction, the anti-damage device is able to elastically obstruct or prevent the stop end from moving away from the stop slot in the first direction.
