The present invention discloses a bassinet that can fold and unfold simply with a press of a button.

A wheel support assembly for a bottom drawer is disclosed. When the bottom drawer is open, the wheel support assembly may provide support in a deployed position. When the bottom drawer is closed, the wheel support assembly may be retracted in a cavity to be invisible to consumers.

The disclosure relates to a support stand structure with a quick-release wheel mechanism, which includes a stand, a detachable wheeled seat, and multiple fasteners. The stand includes a base. The base has multiple slots and a rear wall. The detachable wheeled seat includes a board and multiple wheels. The board has a front plate disposed above the base and a rear plate projecting over the rear wall. The front plate has multiple tabs extended downwardly and inserted in each slot. Each tab has a through hole. The wheels are mounted on a bottom of the rear plate. The fasteners are installed on a bottom of the base. Each fastener includes a movable pin. Each movable pin is attachable to and detachable from each through hole. Therefore, the support stand has the advantages of stability and saving space with detachable wheels.

An article of furniture has retractable and extendable wheels secured beneath each leg. The mechanism for retraction and extension is accomplished by an activation means in mechanical communication with each wheel.

Provided are a truckle structure and a cabinet. The truckle structure comprises: a truckle and a support, wherein the truckle includes a mounting base and a wheel rotatably mounted on the mounting base; the support is composed of a mounting portion located at a lower middle position as well as two connecting portions respectively located on two sides of the mounting portion; the two connecting portions are formed in a manner that the left side and the right side of the mounting portion are upwards bent towards the middle, the support is rotatably connected to the mounting base through the two connecting portions, and the mounting base is located between the two connecting portions; and a mounting hole is formed in the mounting portion, center of the mounting hole and center of gravity of the truckle are on a same straight line, and center of gravity of the support deviates from the straight line. The truckle structure can be directly mounted on the ground and is firmer and more durable.

To avoid or reduce the necessity of loading a cargo container on a container carrying vehicle, for example, a cargo container 100 includes: engaging portions 101b disposed at four corners of each of upper and lower surfaces of a shell 101 and each engageable with a spreader of a container crane; and a wheel 113 capable of supporting the cargo container 100 such that the cargo container 100 is allowed to run. The wheel 113 is switchable between a runnable state where at least a lowermost portion is located below a bottom surface 101c of the cargo container 100 and supports the cargo container 100 such that the cargo container 100 is allowed to run, and a loaded state where the wheel 113 moves inward from the bottom surface 101c and the bottom surface 101c is allowed to make contact with a mount surface of the cargo container 100.

An example article of furniture includes a number of furniture legs having mechanically coupled thereto a respective furniture caster having a rolling component. The furniture casters are movable between (i) an extended position in which their rolling components at least partially extend below bottom surfaces of the furniture legs and (ii) a retracted position in which their rolling components are positioned entirely above the bottom surfaces of the furniture legs. Push-pull cables are mechanically coupled to the furniture casters, and at least one actuator is mechanically coupled to the push-pull cables. When actuated, the actuator applies a pushing force to the push-pull cables, thereby causing the furniture casters to transition from the retracted position to the extended position. When the actuator is not actuated, the pushing force is removed from the push-pull cables, thereby causing the furniture casters to transition from the extended position to the retracted position.

A movable umbrella base comprises a housing (1), a wheel frame (2) disposed under the bottom of the housing (1), at least three wheels (3) connected at intervals to the wheel frame (2) and located partially under the wheel frame (2), a plurality of air bags (4) located inside a space defined by the wheel frame (2) and the housing (1), and a plurality of elastic members (6) limit displacement of the wheel frame (2) and the wheels (3) from the housing (1); when the air bags (4) are inflated, the housing (1) is lifted up relative to the wheel frame (2) and the wheels (3) from the ground; when the air bags (4) are deflated, the housing (1) is lowered relative to the wheel frame (2) and the wheels (3) and contacts the ground. The umbrella base can be moved by the air bags (4), the whole operation process is easier, and it saves more time and effort.
