The present disclosure relates to the field of office furniture, and more particularly to an electric lift table control system and method that realize a resistance back-off. The system comprises a controller, a table (1) and a lifting column (2) for driving the table to move vertically, the lifting column (2) is connected with the controller signal, and further comprises at least one arranged under the table (1) a safety grating (3) for detecting obstacles, each set of safety gratings comprising a transmitting end assembly and a receiving end assembly, and a gap is provided between the safety grating (3) and the lower surface of the table (1), and said The safety light barrier (3) is connected to the controller signal. This will control the lifting column to stop working before encountering obstacles.

A support arrangement (1) for an object (2), comprising primary frame (10), at least three pivoting members (21, 22, 25) and first, second, third and fourth feet (31, 32, 33, 34) fixed to the three pivoting members. The primary frame includes longitudinally spaced first and second stem portions (11, 12) fixed to a longitudinal member (13). The first and fourth feet are laterally spaced and positioned towards a first end of the primary frame and the second and third feet being laterally spaced and positioned towards a second end of the primary frame, the second and third feet being longitudinally spaced from the first and fourth feet. At least one interaction arrangement (50) provides interaction between the three pivoting members such that the four feet can move to accommodate or engage an uneven surface while maintaining control of the object in a position parallel to the average ground plane.

A height adjustment mechanism for an adjustable height table includes an outer sleeve, an inner sleeve, a plug, and a locking mechanism. The outer sleeve is disposed outside the inner sleeve, and the outer sleeve and the inner sleeve are slidable relative to each other. The plug is disposed outside the inner sleeve, and is slidably connected to the inner sleeve. The plug is disposed at an upper end of the outer sleeve, and an outer wall of the plug includes a pressing portion. The locking mechanism operates to push the pressing portion tightly against an outer wall of the inner sleeve to increase the friction between the plug and the inner sleeve, so that the plug and the inner sleeve are relatively fixed.

A folding table, including a table top, a table leg and a first hanged lock for locking the table leg and the table top after the table leg and the table top rotate relative to each other, wherein one end of the first hanged lock is connected with the table top, and the other end of the first hanged lock is connected with the table leg; and the table leg or the table top rotates relative to each other in an unlocked state, the first hinged lock locks the table leg and the table top after an included angle formed between the table leg and the table top is one of 0-90°.

An assembly includes an elongated channel member, a clip and a leg. The clip includes a hook proximate the first end of the clip, a fastener proximate the second end of the clip, and a pivot protrusion disposed between the first and second ends of the clip. The clip is attached to the first end of the elongated channel member. The leg is oriented at a first angle to the elongated channel member and adjacent the first end of the elongated channel member. The leg includes an opening. The hook of the clip is configured for insertion into the opening of the leg. Using the fastener to move the second end of the clip toward a surface of the elongated channel member causes the hook of the clip to rotate about the pivot protrusion, thereby engaging a surface of the leg. A method is described for assembling a structure.

A pressure-adjustable gas spring includes a first gas spring and a gas source for adjusting a pressure. One end of the gas source is connected with the first gas spring and another end is connected with an adjustment device for adjusting the volume of the gas source. The adjustment device includes a cavity for accommodating the gas source and a piston. One end of the piston opposite the gas source is connected with a driving subassembly. The driving subassembly includes a screw. One end of the screw is connected with the piston and another end extends out of the cavity. A nut is arranged on the end of the screw extending out of the cavity. A connection tube is arranged outside the nut in a sleeving manner. One end of the connection tube is connected with the cavity and a rotating block is mounted at an opening of another end.

In various implementations, furniture, such as a table (e.g., a desk) and/or free-standing board, may include an organizational frame to which other members (e.g., table top, white board, smart board, etc.) may be coupled. The frame may include legs and at least one organizational member disposed between two or more of the legs. The organizational member may include a plurality of openings. The opening(s) in the organizational member may be able to couple with one or more organization tools.
