A lifting table stand includes a pair of telescopic columns, a carrier, an actuation module and a passive mechanism. Each telescopic column includes multiple tubes adapted to sheathe with each other and move telescopically relative to each other. The carrier includes a beam straddling the telescopic columns and a pair of support members perpendicularly connected to two ends of the beam. The actuation module includes a receiving member detachably installed to the beam and a driver connected to the receiving member. The passive mechanism includes a transmission shaft and a pair of gear sets installed in the tubes. The transmission shaft passes the driver and is connected to each gear set. Since the receiving member is detachably installed to beam, the actuation module may be changed to different types to control the elevation of the lifting table stand.

A desk frame elevation structure includes an inner tube telescopically received in an outer tube and a roller unit between the inner and outer tubes. The outer tube is fixed to a base and includes a bottom plate and a first top plate. A desk board unit is fixed to the inner tube. A telescopic rod is received in the inner tube and has top and bottom ends coupled to the outer and inner tubes, respectively. The inner tube extends through an upper buffer pad disposed below the first top plate. The upper buffer pad has an upper face abutting the first top plate and a lower face for abutting an abutting edge of the inner tube. A lower buffer pad is disposed above the bottom plate and includes a lower face abutting the bottom plate and an upper face for abutting a bottom end of the inner tube.

A work station including a base includes a work surface pivotally mounted to the base so as to be configured to pivot between a first position and a second position. The work surface is configured to cover a protected member when in a first position and the work surface is configured to uncover the protected member when moved into a second position. The base is configured to support the work surface on a floor surface. A height of the work surface can be adjusted to accommodate the ergonomic needs of different users.

A pneumatic lifting table frame includes a transverse beam, at least one column, a pressure sensor that detects a load of the lifting table frame, a controller configured to receive a signal from the pressure sensor, and an adjustable gas spring assembly configured to drive the column to be lifted or lowered. The adjustable gas spring assembly includes an adjustable gas spring body, a gas reservoir, a piston rod assembly, and a drive unit. The adjustable gas spring body is connected to the gas reservoir via a gas pipe. The controller is configured to control the drive unit, the adjustable gas spring body (401) is disposed in one of the column, and the drive unit drives the piston rod assembly to carry out a piston motion in the gas reservoir.

An elevation structure for a desk frame includes an inner tube telescopically received in an outer tube fixed to a base. The outer tube includes a bottom plate and a first top plate. A desk board unit is fixed to the inner tube. A telescopic rod is received in the inner tube and has top and bottom ends coupled to the outer and inner tubes, respectively. The inner tube extends through an upper buffer pad disposed below the first top plate. The upper buffer pad has an upper face abutting the first top plate and a lower face for abutting an abutting edge of the inner tube in the highest position. A lower buffer pad is disposed above the bottom plate and includes a lower face abutting the bottom plate and an upper face for abutting a bottom end of the inner tube in the lowest position.

A telescopic column (100) for height-adjustable table (120), said telescopic column extending along a longitudinal axis from a first end (102) to a second end (103) of said telescopic column (100), comprising: an outer elongated tube (10) fixedly arranged at said second end (103) of said telescopic column (100), an inner elongated tube (20) having a top end (22) and bottom end (23), wherein said top end (22) defines said first end (102) of the telescopic column (100), and wherein the inner elongated tube (20) is sized and adapted to move into and out of said outer tube (10), drivable by a driving unit (150) along said longitudinal axis between a maximum height (112) and a minimum height (111), and an intermediate element (30) having a lower portion (31) being sized and adapted to engage the outer tube (10) from the inside thereof, a middle portion (32) being sized and adapted to be fitted into the inner tube (20) and engage the inner tube (20) from the inside FIG. 1a thereof, and an upper portion (33) being sized and adapted to be remain within the inner tube (20), so as to provide for stability, wherein said intermediate element (30) is passively moved by means of the inner tube (20) when said telescopic column (100) is moved between said maximum height (112) and said minimum height (111), a motor (150), substantially arranged external to the telescopic column (100), for providing rotary motion to a worm screw (156) extending into the telescopic column (100), and driving a worm wheel (66), a hollow bearing sleeve (60) drivably arranged to the worm wheel (66) from the inside thereof, and coupled to a leadscrew (50) so that the leadscrew (50) rotates about the longitudinal axis with the bearing sleeve (60) driven by the motor (150).

A lifting table stand includes a pair of telescopic columns, a carrier, an actuation module and a passive mechanism. Each telescopic column includes multiple tubes adapted to sheathe with each other and move telescopically relative to each other. The carrier includes a beam straddling the telescopic columns and a pair of support members perpendicularly connected to two ends of the beam. The actuation module includes a receiving member detachably installed to the beam and a driver connected to the receiving member. The passive mechanism includes a transmission shaft and a pair of gear sets installed in the tubes. The transmission shaft passes the driver and is connected to each gear set. Since the receiving member is detachably installed to beam, the actuation module may be changed to different types to control the elevation of the lifting table stand.

A telescopic module includes a first tube, a second tube, a holder, and a plurality of rollers. The first tube has a passageway. The second tube is received in the passageway of the first tube for reciprocation. The holder is mounted on the first tube. The rollers are pivoted on the holder to rest against the second tube or the first tube, or both to touch an inner side of the first tube and an outer side of the second tube to be turned when the second tube is moving.

Provided is a telescopic pole assembly, and a locking and damping assembly therefore.

A multi-functional table is provided. The multi-functional table includes at least one plate, at least one support part connected to the at least one plate and adjusting a height of each of the at least one plate, a communication part receiving user information from a user terminal, and a controller part controlling operations of the at least one support part in response to the user information which is received from the communication part.
