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.

Methods and apparatus to analyze desk heights are disclosed. A disclosed example apparatus includes a distance sensor to measure a distance from a computing device on a table surface to a floor surface, an orientation sensor to measure an orientation of the distance sensor relative to a direction of gravity, at least one memory, instructions, and processor circuitry to execute the instructions to calculate at least one of a first height of the table surface from the floor surface or a second height of at least a portion of the computing device to the floor surface based on the orientation and the distance.

The present invention relates to a linear actuator with an improved electric motor. In particular, the invention focuses on improved technical solutions for braking or locking of a rotating electric motor by using an electro-mechanical locking mechanism. The mechanism uses a solenoid having a nonrotating locking element, which is displaceable by solenoid action and arranged to engage with a rotating locking element. In particular, solutions have been found in which a surprisingly small solenoid with a much-reduced requirement on stroke length may be deployed to effectively unidirectionally or bidirectionally lock against rotation of the motor.

A tabletop assembly, a lifting frame assembly and a height adjustable table are disclosed. The assembling operation of the height adjustable table is simplified by using a supporting part rotatably connected to a table board support and a first terminal block and a second terminal block which are arranged in pairs. During transportation, the height adjustable table may be disassembled into a tabletop assembly and a lifting frame assembly to be packaged and transported, respectively, thus reducing the size of the package. Meanwhile, the lifting frame assembly may be folded, the second terminal block on the lifting frame assembly in a folded state forms an approximate fan-shaped region with the table board support, so that the second terminal block may be protected during transportation. After receiving the goods, the consumer may assemble the tabletop assembly and the lifting frame assembly through a simple process.

The present disclosure discloses an electric lifting media wall, comprising a base, a lifting component including at least one group of lifting columns with lower ends connected to the base and a drive mechanism driving the lifting columns to ascend or descend, a support frame for connection with a display mounting rack that is connected to the lifting columns and ascends or descends along with the lifting columns synchronously, and a wall shroud that shrouds outside the lifting component and the support frame. The electric lifting media wall is adjustable in height, high in bearing capability, multifunctional, convenient in assembly and disassembly, easy for later maintenance, and small in package size.

A furniture assembly includes a top portion and a support frame including a mid-section and a base. The mid-section is configured to be connected between the top portion and the base. The support frame includes at least one cross-member that is configured to be rotated about a swivel joint between a collapsed configuration and an expanded configuration. A foot includes a tip end that is connected to a foot end by a threaded rod, and the tip end is configured to be threaded onto a leg of the mid-section. In addition, the base is configured to be disposed between the mid-section and the foot end of the foot.

Aspects of dynamic workstation apparatus, methods, and systems are disclosed. One aspect disclosed herein is an apparatus comprising a frame; an equipment support that is operable with the frame to position a piece of exercise equipment at a plurality of different equipment support heights relative to the frame; a work surface that is attachable to the frame and selectively positionable at a plurality of different work surface heights relative to the frame, the plurality of different work surface heights including at least a standing height and a seated height; and an actuator that is attachable to and operable with the frame to move the work surface within a range of movement including the plurality of different work surface heights while maintaining an orientation of the work surface relative to the frame.

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.
