Disclosed is a self-locking apparatus for a linear actuator, which relates to the field of linear actuation equipment. The self-locking apparatus includes a one-way bearing and a friction collar, wherein the one-way bearing includes an inner race and an outer race, the inner race being sleeved to the rotary screw of the linear actuator, the friction collar being connected to the outer race; wherein the self-locking apparatus further includes a friction member fitted with the friction collar, such that when the rotary screw rotates forwardly, the outer race does not rotate; and when the rotary screw rotates reversely, the outer race, the inner race, and the friction collar rotate synchronously, such that friction is produced by contacting between the friction collar and the friction member. Further disclosed is a linear actuator applying the self-locking apparatus.

Slider element for lifting columns, preferably for height-adjustable tables, said lifting columns comprise at least two profiles 10,11 arranged telescopically relative to each other, where the slider element 1 has a first slider 2 and a second slider 3 between which there is a designated breaking line 4. The slider element is mounted with the second slider 3 on the outer side of the inner profile 10, and is subsequently guided into the hollow of the outer profile 11, by which the first slider 2 affixes itself to the inner side of the outer profile and when the two profiles are retracted further, the designated breaking line 4 between the first and the second slider 2,3 will break, by which they appear as two separate sliders mounted on a profile each. Thus, a simplified mounting of the sliders is achieved. In addition, it can be constructed such that the sliders are completely concealed within the lifting column.

A lifting table that includes a worksurface, a left table leg assembly, a right table leg assembly, a left table feet assembly, and a right table feet assembly, and a beam assembly. The right table leg assembly. The left table leg assembly and the right table leg assembly vertically support the worksurface. The left table feet assembly is connected with the left table leg assembly. The right table feet assembly is connected with the right table leg assembly. The beam assembly is horizontally connected with the left table leg assembly and the right table leg assembly. The beam assembly includes a plurality of beam components such as a spool assembly and a drive spring. The spool assembly includes an aluminium bracket, a spool, a brake gear, and a gear shaper assembly. The drive spring is connected to the spool through a spool drive rope to power the lifting table. The spool is wound with an active wire rope and an auxiliary wire rope, coiled in opposite directions.

An adjustable lifting column for adjusting a piece of furniture comprises a drive assembly, a threaded spindle assembly comprising at least two concentrically arranged threaded spindles, of which an outer threaded spindle concentrically surrounds at least one further threaded spindle, a telescopic tube assembly comprising three concentrically arranged telescopic tubes, and a driver mechanism having an internal thread. The threaded spindle assembly is located within the telescopic tube assembly. Two adjacent threaded spindles of the threaded assembly have a common threaded connection. One of the at least two threaded spindles in the threaded spindle assembly is connected to the drive assembly for driving this one threaded spindle. The outer threaded spindle also has an external thread in which the internal thread of the driver mechanism engages. The driver mechanism is connected to a middle telescopic tube of the three telescopic tubes.

An electric table stand for simple assembly and adjustment includes a beam structure (10), support bars (20), and upright structures (30). Each of the support bars (20) includes a base (21) and a plurality of arms (211, 212, 213) extended from the base (21), wherein an accommodating space (A) is defined by the base (21) and the arms (211, 212, 213). One arm (213) of each of the support bars (20) supports one end of the beam structure (10), and the beam structure (10) is operatively moved in or out of the accommodating space (A). The upright structures (30) are connected to the support bars (20). Accordingly, it is easy to adjust and position each support bar (20) and each upright structure (30) on the beam structure (10).

A frame for sit-stand-tables comprising a longitudinal member (3), two height-adjustable legs (6, 7) with at least two telescopic profiles, namely an outer and an inner profile, and with a driving mechanism, driven by a motor unit (39), comprising an electric motor (46) and a gear. According to the invention the motor unit (39) is arranged in the longitudinal member (3) and connected to the driving mechanism in the height-adjustable legs (6, 7). Thus, a frame with a simplified construction is achieved. The construction of the legs (6, 7) can be simplified and at the same time the dimensions can be reduced, as it is not necessary to take the building-in of a motor into the legs into consideration. As both legs (6, 7) are driven by a joint motor unit (39), the electric control can also be simplified as it will not have to drive the two legs synchronously.
