A shopping cart includes a frame having a chassis portion and a handle portion extending upward from the chassis portion, a pair of front casters and a pair of rear casters mounted on the frame, and a basket connected to the frame and supported by the frame, the basket defining a chamber for holding articles, where the frame further includes a support structure connected to the chassis and the basket and supporting a portion of the basket. The shopping cart may include a number of wear resistance features that decrease the wear on the cart and extend the life of the shopping cart.

A tote cart, having: a base; a plurality of wheels positioned underneath the base; a pair of upwardly extending supports mounted to the base; and a plurality of cantilevered shelves, wherein each cantilevered shelf is configured to be mounted onto the pair of upwardly extending supports. The cantilevered shelves are removable and re-positionable to different heights on the upwardly extending supports and have a perimeter member spanning around the front and sides of the shelf, and a moveable shelf that can be moved from a first position parallel to the perimeter member to second position at a dropped down angle to the perimeter member.

A galley cart assembly that includes a cart and a wheel assembly attached to the cart. The wheel assembly includes a plurality of wheels and a drive assembly configured to drive one or more of the plurality of wheels to propel the cart. The wheel assembly also includes a primary brake assembly to lock one or more of the plurality of wheels to prevent movement of the cart. Furthermore, the galley cart assembly includes a controller coupled to the cart and including a processor and a memory. The controller includes a turbulence monitoring system configured to detect a turbulence event. The controller is in communication with the wheel assembly, and is configured to automatically operate the primary brake assembly to lock the cart in position when the turbulence monitoring system detects the turbulence event. In certain configurations, an aircraft includes the galley cart assembly.

A tray assembly is provided. The assembly comprises a tray, at least one width reinforcement component affixed to the tray, and at least one length reinforcement component affixed to the at least one reinforcement component.

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.

A cart configured to carry vehicle doors and vehicle roofs includes a bottom frame, a top frame, three front vertical rods, three rear vertical rods, a middle frame, three moving rods, two inner chassis, two side chassis, a rear chassis, and a plurality of universal wheels. The bottom frame includes a front bottom rod, a rear bottom rod, a left bottom rod, and a right bottom rod. The front bottom rod, the rear bottom rod, the left bottom rod, and the right bottom rod are connected end to end. Each two adjacent bottom rods of the bottom frame are detachably installed and connected through a first corner brace and first T-shaped screws. The top frame is arranged directly above the bottom frame. A shape and a size of the top frame are same as a shape and a size of the bottom frame.

A bag for storing tennis balls has an hermetic enclosure formed of flexible material, an opening larger than a tennis ball into the enclosure, the opening having a hermetic sealing zipper by which the opening may be opened and closed, and a flexible tubing from outside the enclosure through the flexible material, the flexible tubing having an open end adapted to engage an air pump, and a one-way valve adapted to admit air into the enclosure and to prevent air from exiting the enclosure through the tubing. Tennis balls placed into the bag are placed under pressure higher than the pressure inside a tennis ball by closing the opening by closing the hermetic sealing zipper, engaging an air pump to the open end of the flexible tubing, and operating the air pump until a predetermined pressure is established in the bag.

An object to provide a brake device for a caster that has a simple structure, provides reliable braking, has no risk of damaging the circumferential surface of a roller, and has high durability. The brake device for a caster includes: a plurality of projecting parts formed concentrically at regular intervals on opposite side-surfaces of a roller in a direction in parallel with the axis, and levers set across the roller at both side-panels of a fork so as to be opposed to the projecting parts, and a claw formed at a tip of each of the levers so as to be opposed to the projecting parts, wherein the levers are operated so that the claw is engaged with a concave part formed between the projecting parts, thereby locking rotation of the roller.

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, a propulsion means, and/or a maneuverability 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.
