A compact and easy to assemble grill cart to support a collapsible grill cart that includes a base portion, to which side frames can be coupled, and that permits the grill cart to be stored in a compact, folded configuration. The side frames of the cart can be expanded or unfolded to provide a stable structure that can support a cooking unit, such as a grill, grill insert, or firebox. Such a collapsible grill cart can also include doors that provide enclosed storage space within the expanded cart and wheels to facilitate transportation.

Compressible carts and methods for using the same are provided. The compressible carts include a rigid frame having a front wall, a rear wall, a right sidewall, a left sidewall, a bottom wall, a rotatable base panel, a rigid cover panel, a handle, and a plurality of wheel assemblies. The compressible carts may also include on each sidewall one or more fastening mechanisms, such as slideable members cooperatively engaging tracks or fastening connectors, and are movable between an open position to allow the sidewall to fold inwardly, to a closed position to selectively lock the panels of the sidewall. The plurality of wheel assemblies may include a plurality of rotatable swivel wheels mounted underneath the bottom wall, or a plurality of wheels rotatably coupled to a plurality of spokes, where each spoke is coupled to a revolving spindle.

Multi-level delivery systems and various apparatus associated therewith are presented. Multi-level delivery systems include a number of integrated, modular and interchangeable compactible elements that may work either alone or in conjunction with other such elements to allow for the deployment of a delivery system having a smaller overall spatial footprint when compared to comparable conventional delivery systems. Apparatus combining to form a delivery system may include one or more of: a compactible container cart, a compactible cart hauler or trailer and a propulsion means. These elements or apparatus may be deployed in any combination, either together as an integrated system or with compatible conventional apparatus. In combination, delivery systems maximize space efficiency, and allow for adaption to any environment and scale.

A foldable wagon has a frame that is collapsible in a manner such that the wagon basically has the same vertical height when in the collapsed and expanded configurations. The frame has folding bar assemblies on its sides. As the wagon is altered from the expanded to the collapsed configurations, the lower leg outer end of each of the pair of folding bar assemblies slides downward relative to the corresponding upper leg outer on the respective vertically oriented pole. The pairs of folding bar assemblies increase in height and decrease in length. As wagon is altered from the collapsed to the expanded configuration, the lower leg outer end of each of the pair of folding bar assembly slides upward relative to the corresponding upper leg outer end s on the respective vertically oriented pole, and the pairs of folding bar assemblies decrease in height and increase in length.

A double-decker collapsible cart includes a front frame, a rear frame, a first folding mechanism, a second folding mechanism, and front and rear wheels. The second folding mechanism includes a front-upper base frame and a rear-upper base frame articulated with each other, a front-lower base frame and a rear-lower base frame articulated with each other, and a support linkage rod. The front-upper base frame and the front-lower base frame are hinged to the front frame, and the rear-upper base frame and the rear-lower base frame are hinged to the rear frame. One end of the support linkage rod is connected to a joint of the front-upper base frame and the rear-upper base frame, and the other end is connected to a joint of the front-lower base frame and the rear-lower base frame. A bottom cover is disposed on the front-upper base frame and/or the rear-upper base frame.

The invention discloses a novel sheet folding trailer, comprising pocket component, front-frame component, rear-frame component, bottom-frame component, wheel component, handle component, wherein vertical skeleton unit of the invention comprises front-frame component and rear-frame component, the pocket component is arranged between front-frame component and rear-frame component, the bottom-frame component comprises front bottom-frame component, rear bottom-frame component, bottom-frame U-shaped hinge, drive tube component, the wheel component comprises universal wheel fork a, universal wheel fork b, directional wheel fork a, directional wheel fork b, torque tube a, torque tube b, the handle component is arranged at one side of front-frame component, the handle component and the front-frame component are connected through linkage component. Through structural optimization, the invention has a small folding height, a large capacity after opening, and has a simple side structure by adopting only two parts, which effectively reduces the product cost, moreover, the folding height thereof will not change.

To provide a moving device that can be used as a mobility device to transport objects and can be improved in portability. The moving device that is movable with rotation of wheels includes a body unit inflated by injection of fluid and deflated by discharge of the fluid, a support body provided on a predetermined surface of the body unit, and the wheels provided in the support body, wherein the interior of a predetermined portion of the body unit that receives a load from an object contacting the body unit is formed with a drop-stitch structure, and the drop-stitch structure after injection of the fluid has tensile forces in directions approximately perpendicular to the direction of the load applied to the predetermined portion by the object.

A mobile sheltered workstation includes a housing. The workstation includes a main support member having a lower end coupled to the housing and extending upwardly therefrom, the main support member being length adjustable and telescopically movable between a retracted configuration and an extended configuration. A canopy framework includes a lower end selectively coupled to an upper end of the main support member and movable between a stowed configuration adjacent the housing and a deployed configuration displaced from the housing. A canopy is selectively coupled to the canopy framework and configured to cover a geometric area thereof.

A foldable wagon assembly is disclosed herein including multiple features. In one aspect, a push handle is provided that includes pivoting connections located inward from a longitudinally outermost edge of a frame of the wagon. In another aspect, an upper end of the frame includes at least one slot for securely attaching a soft goods enclosure to the wagon. A pull handle is also provided that can be securely attached in a generally upright position via a retention clip formed on the frame of the wagon.

The invention is a wheeled folding tray cart and method. The wheeled folding tray cart comprises a collapsible wheeled framework pivotally supporting a set of split shelves, each split shelf comprises a pair of half shelves. The wheeled folding tray cart moves between an open operating position wherein the set of split shelves are held in spaced-apart, stacked, horizontal orientation within the collapsible wheeled framework and a closed storage position wherein the collapsible wheeled framework is collapsed in manner to move each half shelf pair into an accordion-like, inverted “V”-shaped or accordion like configuration. An extension coiled spring attached to the collapsible wheeled framework assists in the movement of the wheeled folding tray cart between open operating position and the closed storage position. A sheath encloses at least a portion of the spring to provide resistance to the spring's movement to limit potential operator exposure to pinch injuries.
