A foldable and height-adjustable table may include a main frame, a foldable frame, and a wheel assembly. The main frame has two side frames which are separated with a distance and parallel with each other. Each of the side frames has a vertical front sleeve and a vertical rear sleeve, and each of top bars horizontally located at a top end of the side frame. A table top has a pivotal side edge pivotally coupled with one of the top bars and an opposed detachable side edge detachably coupled with another top bar. The table top is configured to be coupled on tops of the top bars for use or pivotally turned over to couple at an outer edge of the side frame for store, and the main frame is configured to be folded between the folded position and unfolded position.

A table leg includes a fixed outer tube, a movable inner tube vertically movable in the fixed outer tube and having two pairs of parallel walls, and a plurality of rotating members rotatably mounted to one pair of the parallel walls of the movable inner tube and partially protruding out from an outer surface of the movable inner tube and stopped against an inner surface of the fixed outer tube, such that the rotating members are rotatable when the movable inner tube is moved relative to the fixed outer tube.

The present application relates to a telescopic column (1) comprising a lower part (10) having a first end constituting a first end (4) of the telescopic column, an upper part (20) telescopically moveable relative to the lower part and having a first end constituting a second end (5) of the telescopic column opposite said first end of the telescopic column, a drive mechanism (2) configured to provide telescopic movement between the lower part and the upper part, an cable (30) extending inside the telescopic column, and a cable guiding means (50) coupled to a tensioning device (52) arranged at the second end of the telescopic column. The tensioning device is configured to control the position of the cable guiding means in the telescopic column based on the telescopic extension of the column, and the cable extends through the column via the cable guiding means. The present application further relates to an adjustable furniture (100) comprising at least one telescopic column.

An adjustable table leg includes a leg outer pipe, a leg middle pipe, a lead screw outer pipe, a lead screw inner pipe, an outer lead screw, an inner lead screw, an outer lead screw nut, an inner lead screw nut, a motor casing, and a drive motor. Thereby, the upward and downward transmission is more stable, the stress of the inner lead screw nut and the outer lead screw nut is more uniform, the fatigue degree is reduced, and the service life is increased. In particular, its structural design is ingenious, the overall layout is reasonable, and the installation is simple.

A desk within a work surface or table such that the desk can be raised and lowered to any desired position in relation to the work surface using an actuator that controls the use of telescoping legs or rods. During the process of returning the desk back to its original flush, or in horizontal seamless alignment with, the rest of the work surface, a knee action safety device co-acts, or in combination, with a gas spring is used for controlling the lowering of the desk and creating a virtually weightless of desk during final descent; thus, eliminating the possibility of a person's limb or hand being crushed or severely injured, even if these are providing obstruction.

A height-adjustable multifunctional table includes a base, at least two independent and height-adjustable table legs, a retaining frame, a tabletop, a power adapter, a controller, and a hand controller. Through the wireless connection between the hand controller and the controller, the controller is used to control a driving mechanism, and the driving mechanism drives a movable inner tube to move up and down so as to adjust the height of a tabletop. The user only needs to control the hand controller to adjust the height of the tabletop. The height adjustment is easy and more convenient and saves time and labour.

Described herein are apparatuses (such as desks) with adjustable top panels. In some embodiments, an apparatus includes a frame, having a movable component that is configured to move upwards and downwards. The apparatus also includes: a first top panel attached to the movable component and configured to move upwards and downwards with the movable component, and a second top panel attached to the frame and aligned parallel to the first panel, so that the first panel is adjustable to be flush with the second panel or adjustable to a level above the second panel. The apparatus can also include a barrier panel attached to the frame or the first panel, arranged perpendicular to the first and second panels and oriented downward from the first panel at a side of the first panel closest to the second panel.
