Abstract: 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.

Abstract: A telescopic module, which may be incorporated in a desk or a chair to elevate or lower a work surface, 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. The rollers may reduce the friction between the first and the second tubes when the second tube is moving.

Abstract: A height adjustable desk includes a work surface, a first telescoping leg, a second telescoping leg, a driving device, and a switch device. The first telescoping leg and the second telescoping leg are connected to the work surface, and are driven by the driving device to lift or low the work surface to any desired height. The switch device is mounted on the first telescoping leg to be activated when the work surface is moved to a predetermined position. The switch device will turn the motor off to stop the work surface when the switch device is activated.

Abstract: A pressure adjusting device of a quick fixture includes a main member, a fixed member fixed to the main member, a movable member movably connected to the main member, and an elastic member received in the main member and having opposite end connected to the fixed member and the movable member to urge the movable member. With the pressure adjusting device the quick fixture can fix various workpieces with different thicknesses.

Abstract: A workstation includes a partition unit to form a workspace, in which a desk board, two lifting mechanisms are provided. Each of the lifting mechanisms has a linkage set and a movable member connected to the linkage set. The linkage sets are moved by one or more motor, and the movable member is connected to the desk board. The motor moves the linkage sets so as to lift and lower the desk board.

Abstract: A telescopic module includes a first tube having a passageway therein; a second tube received in the passageway of the first tube for reciprocation; a hub connected to the second tube; a roller pivoted on the hub to touch the inner side of the first tube; and an adjusting member. The hub is provided with an expanding hole and flexible portions. The roller is pivoted on the flexible portion, and the adjusting member is inserted into the expanding hole and abuts against the flexible portions to move the roller outwardly.

Abstract: A workstation includes a partition unit to form a workspace, in which a desk board, two lifting apparatuses and a driving device are provided. Each of the lifting apparatuses has a first tubular member connected to a bottom of the desk board, a second tubular member fixed to the partition unit, and a lifting device to move the first tubular member relative to the second tubular member. The driving device is connected to the lifting devices to drive the lifting devices to move the first tubular members so as to lift and lower the desk board.

Abstract: A workstation includes a partition unit to form a workspace, in which a desk board, two pneumatic devices and a synchronizing device are provided. Each of the pneumatic devices has a fixed section and a movable section while the fixed section is fixed to the partition unit and the movable section is connected to desk board to lift and lower the desk board. The synchronizing device is connected to the pneumatic devices to synchronize movements of the pneumatic devices.

Abstract: A desk includes a base and a work surface assembly mounted on the base. The work surface assembly has a board and a leg having opposite ends connected to the board and the base. The leg has an inclined section and a straight section, and the board has a first end and a second end opposite to the first end. A distance between the first end of the board and the straight section of the leg is greater than that of between the second end of the board and the straight section of the leg. The boards of the work surface assemblies are arranged in a row or two rows of a matrix. Therefore, the work surface assemblies are combinative to be mounted on the base to have various layouts of the boards.
