The invention relates to a supporting frame with a lifting column (59) comprising telescopically arranged profiles with an upper and lower end, said upper end having a housing (60) secured thereto, and a base unit (61,62,63) with a compartment at least for partial reception of the lifting column housing (60) and a locking element (75), which when placed in a locked position exerts a squeezing force between the base unit (61,62) and the housing (60) of the lifting column (59). Thus, the housing (60) of the lifting column (59) is positioned and fixed in the base unit (61,62,63). The supporting frame further comprises means for retaining the locking element (78) in the locked position.

An adjustable table leg includes a leg outer pipe, a leg middle pipe, a lead screw outer pipe, a lead screw inner pipe, an outer lead screw, an inner lead screw, an outer lead screw nut, an inner lead screw nut, a motor casing, and a drive motor. Thereby, the upward and downward transmission is more stable, the stress of the inner lead screw nut and the outer lead screw nut is more uniform, the fatigue degree is reduced, and the service life is increased. In particular, its structural design is ingenious, the overall layout is reasonable, and the installation is simple.

A desk within a work surface or table such that the desk can be raised and lowered to any desired position in relation to the work surface using an actuator that controls the use of telescoping legs or rods. During the process of returning the desk back to its original flush, or in horizontal seamless alignment with, the rest of the work surface, a knee action safety device co-acts, or in combination, with a gas spring is used for controlling the lowering of the desk and creating a virtually weightless of desk during final descent; thus, eliminating the possibility of a person's limb or hand being crushed or severely injured, even if these are providing obstruction.

An ergonomically designed space saving, collapsible multi-function travel-friendly modular workstation for supporting a broad range of electronic systems, reading materials and the like for users while standing, sitting or on-the-go, and fits in anywhere, anytime is presented. The workstation comprises a support unit, telescopic rod and tripod and is designed to provide needed cooling and ventilation for electronic systems, support healthy postures, and complete comfort and versatility of a multi-function workstation with all the important things needed when working at a desk, thereby improving a user's comfort when using the workstation. Further, the workstation is designed for easy transportation, storage and set up, as well as provide a versatile workspace for a user in many different environments, for everyday use such as note taking, writing, reading, presentations, performing arts and rehearsing while playing a musical instrument, music or conductor stand, etc.

A mobile workstation with adjustable height of the present disclosure may comprise a top assembly, an adjustment assembly, and a bottom assembly. Adjustment assembly may comprise telescopically engaged segments. One or more pulleys or pulley assemblies may be disposed within one or more of the segments to allow for withdrawing and retracting segments from one another at the same rate. Actuation of the raising or lowering of the overall height of the mobile workstation may be realized through either a manual actuation or an electronic element such as a linear actuator.

A telescopic leg and method of assembly for the telescopic leg, which is generally configured to raise and lower a work surface while supporting it. The telescopic leg includes at least two segments, one of which includes a visible cap through which one of the segments is inserted to trim an opening that matches the profile of the segment doing the trimming and can create an interference fit.

A telescopic post includes a tube set, a power unit, a rotation unit, a threaded tube unit and a threaded rod unit. The tube set includes internal tube inserted in an intermediate tube inserted in an external tube. The power unit is supported on the internal tube. The rotation unit is inserted in the internal tube. The rotation unit is connected to the power unit so that the power unit drives the rotation unit. The threaded tube unit is connected to the rotation unit so that the rotation unit rotates the threaded tube unit. The threaded tube unit is connected to the internal tube so that the threaded tube unit translates the internal tube. The threaded rod unit is connected to the threaded tube unit and the intermediate tube so that the threaded tube unit rotates the threaded rod unit and the threaded rod unit translates the intermediate tube.

The invention relates to a telescopic column (2) and a method for collapsing and extending the telescopic column (2) for a height adjustable furniture. The telescopic column (2) comprising an outer column (210), an intermediate column (220), an inner column (230) and a fixating member (400) configured to fixate the height position of the intermediate column (220) at a predetermined height position relative the outer column (210) when said telescopic column (2) is in an upper stroke range. Wherein the inner column (230) is adapted to be driven by a driving unit and comprises a first engaging portion for interacting with the fixating member (400) such that the fixating member (400) is disengaged and enables the inner column (230) to move in tandem with the intermediate column (220) relative the outer column (210), when the telescopic column (2) is in a lower stroke range and wherein the fixating member (400) is resiliently loaded.

A height-adjustable piece of furniture includes a lower part, an upper part, an actuating device, first and second reference sections and a deformation sensor. Distance between the lower and upper parts can be adjusted by the actuating device. The deformation sensor is arranged to detect change between the first and second reference sections and is connected to the actuating device such that a signal of the deformation sensor can be transmitted to the actuating device. The actuating device is configured to stop the change in distance between the lower and upper parts if the signal transmitted by the deformation sensor corresponds to a change in distance that exceeds predefined threshold values. A cable protector is also provided for a cable to be mounted, and is coupled to the first and second reference sections such that tensile force acting on the cable causes change between the first and second reference sections.
