A control circuit applied to a lifting platform controls a motor to adjust the height of a platform. The control circuit includes an AC/DC conversion circuit, a DC/DC conversion circuit, a detection unit, and a control unit. The detection unit detects an output end of the AC/DC conversion circuit and provides a detection signal. The control unit provides a PWM signal according to the detection signal to control the DC/DC conversion circuit so that the DC/DC conversion circuit converts a DC voltage to an output voltage. When the control unit realizes that the DC voltage or a DC power provided by the AC/DC conversion circuit is less than a power supply threshold according to the detection signal, the control unit decreases a duty cycle of the PWM signal to maintain the DC voltage or the DC power to be greater than or equal to the power supply threshold.

Electrical operating unit comprising a first and a second part, where the two parts can be mutually adjusted. The Operating unit (1) comprises a first part constructed as a housing (2), which contains the electric equipment with at least one electric switch and a second part constructed as a mounting unit (3) for the first part. The two parts are interconnected about a shaft (17), or pivot, so they can rotate mutually. When the operating unit is mounted the housing (2) will assume a first position, an initial position. By pressing the housing (2) it rotates about the shaft (17) and is brought into a second position, an activation position, where the switch(es) is/are activated in that they are pressed against the second part (3). With this embodiment of the operating unit the piece of furniture can be adjusted in either direction by pressing the housing (2). The housing (2), besides from functioning as a switch, can also be equipped with other switches and displays.

The present application relates to a height-adjustable table including a table plate. a table leg is fixedly connected to a side surface of the table plate, two brackets are arranged oppositely on the side surface of the table plate, and a retaining plate is fixedly connected to opposite inner sides of the two brackets, respectively. A control box is provided, a retaining clip is fixedly connected to the control box, and the retaining clip is detachably connected to the retaining plate.

Four types of telescoping modules are disclosed wherein the first type has a pair of opposed female ends, the second type has a pair of opposed female ends, and the third type has a female end and an opposed male end. The fourth type has two opposed male ends between which a positionable threaded rod and retaining components stably extend the length between the male ends of the telescoping module. Alternatively, the fourth type of telescoping module may have a female end and a male end. Each of the male ends of the second, third, and fourth types of telescoping modular components comprises a cylindrical body with one or more linear set(s) of two or more spaced-apart prongs on the circumferential surface of the cylindrical body. Each of the female ends has a cylindrical receptacle with one or more linear channels and/or prong-retaining slots for receiving therein the cylindrical body.

A lightweight electric desk stand includes a beam structure (10), a telescopic column (20) and a flank (30). The beam structure (10) includes a lower frame (11) and an upper frame (12). The lower frame (11) includes a bottom plate (111) and two risers (118) facing one another. The upper frame (12) includes a top plate (121) and two side plates (125) facing one another. The upper frame (12) is mounted on the lower frame (11). The side plate (125) and the riser (118) are connected to one another. The bottom plate (111) and the top plate (121) are spaced and facing one another. The telescopic column (20) is connected to two ends of the beam structure (10) and includes a motor (21). The flank (30) is disposed on an edge of the telescopic column (20) and covers an end of the beam structure (10).

The present invention relates to an improved height-adjustable table (1) which can assist and motivate the user to use the height-adjustable table in a manner which increases health, calorie burn and well-being. The table features a communication interface for connection of a user specific device providing the control with a set of user values for that specific guest user of the height-adjustable table in order to ease the configuration of the table to fit each individual user.

Disclosed is a multi-communication height adjustable desk system including a lifting column for adjusting lifting of a desk top, a drive motor for driving lifting of the lifting column, a controller for sending drive instruction to the drive motor and a manual controller for sending control instruction to the controller. It further includes an intelligent terminal stored with set height of the height adjustable desk. Manual controller includes a first communication module for communicating with the intelligent terminal. Manual controller receives authentication instruction sent by the intelligent terminal through the first communication module. After authentication instruction is verified, first communication module receives set height data of the height adjustable desk sent by intelligent terminal and sends control instruction to controller according to set height data of the height adjustable desk. Controller sends the drive instruction to drive motor according to control instruction for adjusting height of the lifting column.

A height-adjustable office furniture comprising a table top, at least one height adjustable leg unit and a drive unit to drive adjustment of the height of the leg, a drive control system configured to control and power the drive unit and an anti-collision system connected to the drive control system and configured to detect when movement of the table top along the vertical direction Z is blocked. A resilient element is provided in the connection between the drive unit and the table top, the resilient element defining a suspension travel extending along a vertical direction Z to reduce vibrations.

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.

An electrically adjustable table system includes a table, at least one electric drive for adjusting the table, a voltage supply, a control and a bus system. The at least one drive, the voltage supply and the control are connected to the bus system. The bus system comprises multiple multiwire cable sections, which are electrically connected to one another via insulation displacement connectors.
