A household appliance includes a housing, height-adjustable levelling feet arranged on an underside of the housing, and height-adjusting devices for adjusting a height of the leveling feet, respectively. Each height-adjusting device includes an adjustment housing fixed to the housing, a threaded shaft passing vertically through the adjustment housing in an interlocking manner and including a foot plate, a worm wheel as an output gear at an outer circumference thereof which is mounted rotatably in the adjustment housing and threadably engaged with the threaded shaft, and a worm connected to an adjusting rod and forming a drive gear for driving the worm wheel. The threaded shaft can have along a length thereof a flattened section which rests against the adjustment housing at one point at least, or two flattened sections arranged on opposite sides of the threaded shaft, or two axially extending grooves arranged on opposite sides of the threaded shaft.

A telescopic foot for furniture and/or furnishing items includes a hollow body housing a supporting foot designed for telescopically sliding therein using an internal control or kinematic mechanism, which is actuated by a control transmission bevel gear positioned between a first actuation opening of the bevel gear and a second telescopically sliding opening of the supporting foot, both defined in the body of the foot, one laterally and the other one axially and in orthogonal positions to each other, so as to each receive an element of the bevel gear. Sliding elements enable the sliding of the supporting foot with respect to the body of the foot, and engagement and retention elements engage the supporting foot and the hollow body of the foot.

An attachment for furniture feet adjustable in height with respect to a piece of furniture includes a body having a seat adapted to firmly receive an upper end of a foot adjustable in height, four pass-through openings for the passage of a maneuvering tool of an adjustment mechanism of at least one additional foot adjustable in height, the openings being arranged at 90° with respect to each other and lying along two symmetry axes, orthogonal to each other, of the body.

A system for automated equipment cabinet leveling may include a foot leveling device for each foot of an equipment cabinet, each foot leveling device comprising a drive gear and a worm gear; a motor for each foot leveling device, each motor driving the worm gear of one of the foot leveling devices; a controller controlling the operation of each motor; and a sensor positioned on a portion of the equipment cabinet to be leveled that detects an orientation of the equipment cabinet and provides orientation data to the controller. The foot leveling device may interface with a foot shaft of the cabinet foot by a drive shaft driven by the drive gear, and the controller may drive at least one of motors to level the surface of the equipment cabinet based on the orientation data by extending or retracting at least one of the cabinet feet.

A foot system for parts of furniture and furnishing items with front adjustment levelling, wherein a foot (11) is positioned between a base or bottom (12) of a piece of furniture and a floor (P) in a space reduced in height (H), said foot (11) containing in its interior a height adjustment mechanism actuated from a hole or actuating point (13) by means of a manoeuvring tool (14), the hole or actuating point (13) being positioned, in the system, at a lower free end of the foot (11) resting on the floor (P).

A compact front adjustment system for leveling feet for furniture (M) with a bottom (12) and shoulders (11), comprising: at least two front feet, a right foot (13d) and a left foot (13s) and at least two rear feet, a right foot (14d) and a left foot (14s), wherein each of said rear feet (14d,14s) comprises an adjustment mechanism in height, which is accessible from outside the foot through respective holes (21d,21s) and which can be maneuvered by means of a maneuvering tool (18). According to the invention, a respective supporting and guiding unit (17d,17s; 22; 25) for said maneuvering tool (18) is provided in combination with said rear feet (14d,14s), said unit being assembled on said bottom (12) of the furniture (M) in an intermediate position between said front feet (13d,13s) according to an axis X which is aligned with said holes (21d,21s) for access to the adjustment mechanism in height of the respective rear foot (14d,14s).

A foot system for parts of furniture and furnishing items with front adjustment levelling, wherein a foot (11) is positioned between a base or bottom (12) of a piece of furniture and a floor (P) in a space reduced in height (H), said foot (11) containing in its interior a height adjustment mechanism actuated from a hole or actuating point (13) by means of a manoeuvring tool (14), the hole or actuating point (13) being positioned, in the system, at a lower free end of the foot (11) resting on the floor (P).

The telescoping adjustable leg comprises a tubular housing, a tubular toe, a cylindrical toe, a base and an externally threaded rod. The adjustable leg 10 is expandable from a fully retracted position to a fully extended position by rotation of the housing and cylindrical toe relative to the tubular toe.

A compact front regulation system for leveling feet of furniture pieces having a bottom and shoulders includes, in combination, at least one front foot and at least one rear foot, the at least one rear foot having a regulation mechanism in height which is accessible from the outside and which can be maneuvered using a regulation tool. The at least one front foot has a pass-through hole for the regulation tool of the rear foot, the pass-through hole acting as a support and a guide for the regulation tool.

The adjustable equipment leg comprises a housing assembly for mounting within a piece of equipment and a toe assembly mounted on the housing assembly for vertical adjustment for raising and lowering the piece of equipment. The piece of equipment is constructed with a floor and the housing assembly is disposed on the floor within the piece of equipment thereby being hidden from view.
