A hydraulic leveling base comprises a bracket which can be used in a combination and connection manner or independently and a leveling foot mounted below the bracket. Above the bracket is a supporting surface for bearing. A hydraulic medium is provided inside the leveling foot and can flow inside the leveling foot and/or between the leveling feet to achieve the leveling. In the present disclosure, the leveling foot is provided below the bracket of the hydraulic leveling base, the hydraulic medium flows inside the leveling foot and/or between the leveling feet, and so the amount of compression of the leveling foot under bigger pressure is large, the leveling foot under smaller pressure can extends by the action of the liquid pressure, and then automatic height leveling can be achieved.

The bottom of a washing machine is provided with feet that compromise a fixed part and a movable part, and a hollow chamber is formed between the fixed part and the movable part. The hollow chamber is provided with a hydraulic medium. The feet are connected by high-pressure oil pipes, to communicate hollow chambers of the feet. Under the action of pressure, the hydraulic medium can be circulated between hollow chambers of connected feet to realize the expansion and contraction of the movable part, to execute automatic leveling. Under different pressures, the foot is made to automatically adjust adaptively due to the fluidity of the hydraulic medium. The hydraulic medium can flow between the feet, so the adjusting range is larger and can achieve better results.

In legged furniture having four or more legs and a load-receiving stage supported directly or indirectly by these legs, this legged furniture includes three main legs defining a triangular shape in a plurality of the legs and, assuming that the legged furniture is placed by using only the main legs, enabling a stable stationary attitude of the load-receiving stage, and a leg adjuster forming an extension portion of a sub leg other than the main legs and capable of expansion/contraction in a vertical direction and providing an expansion/contraction leg in cooperation with the sub leg and autonomously allows expansion or contraction of the expansion/contraction leg on the basis of a length of the main leg in accordance with the stationary attitude of the load-receiving stage.

A cabinet assembly includes a base and walls secured to the base to define an interior. The cabinet assembly further includes a pivot pin coupled to the base and a locking device coupled to the base. The locking device is movable relative to the base between an engaged position and a released position. The cabinet assembly additionally includes a support foot. The support foot is fixed to the base in a first orientation when the locking device is in the engaged position. The support foot is movable about the pivot pin to a second orientation spaced from the locking device when the locking device is in the released position.

A platform leveling apparatus with a platform attached to a frame, two and only two linear actuators, and one and only one heim joint. The upper ends of the linear actuators are rotatably attached to the front frame member, and the heim joint is connected to the rear frame member. The lower end of the heim joint is connected to an upper end of a heim joint support, and the lower end of the heim joint support is connected to a rear base support by front and/or rear heim joint braces. The rear base support is oriented parallel to the rear frame member when the heim joint is at a centered position, and the rear base support is positioned below a front edge of the rear frame member. The lower ends of the linear actuators are rotatably connected to a first fixed surface.
