A telescopic tube assembly includes an outer tube and an inner tube which is telescopically inserted in the outer tube. A first stabilizing unit and a second stabilizing unit respectively located in a gap between the inner and outer tubes to make the inner tube stably moved relative to the outer tube. The first stabilizing unit includes two plates. The outer surface of each of the two plates 31 is in contact with the inner surface of the outer tube, and the inner surface of each of the two plates is in contact with the outer surface of the inner tube. The inner tube is easily assembled to the outer tube by the first and second stabilizing units.

A portable, convertible, and modular lap desk for use with various types of electronic devices. In some cases, the lap desk may be configured with extendible legs to provide a plurality of adjustable height positions. For instance, the legs may include a closed position, a partially extended position, and a fully extended position for use in different situations. The lap desk may also include on board power supplies, various compartments for storing the electronic devices and on boarding cabling and cable routing to more efficiently organize and couple multiple devices.

A glide bearing for guiding axial movement between inner and outer telescoping columns may include first and second spaced apart contact surfaces, and a resilient wall extending therebetween and having an outer convex surface defining an apex. A span between the apex and a plane defined between the first and second contact surfaces is greater than a width of a space between the outer surface of the inner column and the inner surface of the outer column. The glide bearing is configured to be disposed within the space with the first and second contact surfaces contacting the outer surface of the inner column, with the apex contacting the inner surface of the outer column and with the resilient wall deflecting inwardly toward the plane to accommodate the space in response to a force of the inner surface of the outer column acting against the apex.

The invention is about a synchronous lifting mechanism, with a first inner fixed tube and a second inner fixed tube and that the synchronous lifting mechanism has a synchronizing mechanism, the synchronizing mechanism include a first support of which one end is in clearance fit with the inside of the first inner fixed tube and a second support of which one end is in clearance fit with the inside of the second inner fixed tube.

A height adjustable table can include a plurality of legs, a lower portion, a worksurface, a height adjustable surface, and a linkage. The worksurface can be supported by the plurality of legs and can include a fixed surface and a height adjustable surface. The fixed surface can be secured to at least one of the lower portion and the plurality of legs, and the fixed surface can define a recessed portion. The height adjustable surface can be movable between a raised position and a lowered position so that the height-adjustable surface retracts into the recessed portion when in the lowered position so that the height adjustable surface is coplanar with the fixed surface. The linkage can be configured to move the height adjustable surface between the lowered position and the raised position so that the height adjustable surface remains parallel to the fixed surface.

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.

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.

A table includes a table top with at least one collapsible leg which includes a top tube, a middle tube and a bottom tube. A connector is connected to the underside of the table top and the top end of the outer tube. An inner threaded rod is connected to a motor which is connected to the connector. An outer threaded rod is movably mounted to outside of the inner threaded rod. A top nut is fixed to the middle tube and threadedly connected to the inner threaded rod. A bottom nut is connected to the bottom tube and threadedly connected to the outer threaded rod. When the motor drives the inner threaded rod, the outer threaded rod is moved relative to the inner threaded rod so that the middle tube moves relative to the top tube, and the bottom tube moves relative to the middle tube.

A desk includes a tabletop and at least one base member supporting the tabletop. A footrest is disposed on the at least one base member beneath the tabletop. The footrest is movable between a stowed position toward a back of the desk and a deployed position toward a front of the desk. At least one mechanism is disposed on the at least one base member and operatively coupled to the footrest. The at least one mechanism moving the footrest between the stowed and deployed positions. A floor mat is disposed with the footrest. The floor mat is movable with the footrest between a stowed mat position and a deployed mat position.
