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 fastening screw and a height-adjustable table using the same are provided. A threadless transition portion is provided between a threaded section and a head portion of the fastening screw to increase the contact area between the screw and a workpiece, and to cooperate with a shaft portion to fasten the workpiece. The transition portion is provided with a tapered wall surface, and the transition portion expands from the threaded section to the head portion of the screw. The screw offers a tension expanding outward in a circumferential direction of a mounting portion. An area of a joint between the transition portion and the head portion does not exceed a circumferential area of threads. In a direction of a central axis of the screw, the projection of the transition portion overlaps that of the shaft portion, which prevents the transition portion from falling off the workpiece or damaging the workpiece.

Disclosed is an electric height adjustable folding table, including: a table stand, the table stand including a crossbeam, two ends of the crossbeam being respectively mounted with an electric height adjustable upright; wherein a positioning elongated slot is provided on the crossbeam, and the electric height adjustable upright includes a positioning axle via which the electric height adjustable upright performs rotative and sliding movements in the positioning elongated slot; and when the electric height adjustable upright is at a first position, the positioning axle is at a proximal end of the positioning elongated slot and maintains a spread-out angle with respect to the crossbeam; and when the electric height adjustable upright is at a second position, the positioning axle slides to a distal end of the positioning elongated slot, and meanwhile the positioning axle rotates in the positioning elongated slot towards the center of the crossbeam, thereby implementing folded reception.

A lifting device with a cable management is provided. The lifting device includes: an outer pipe, an actuation mechanism, a linkage member, a cable, and a cable management component. The actuation mechanism is accommodated in the outer pipe and has a motor and a screw rod. The linkage member is accommodated in the outer pipe and mutually screw-fitted with the screw rod to operate, and moves relative to the outer pipe. The cable has a spiral coiled cable unit. A shaft core line in parallel with the screw rod is defined by the spiral coiled cable unit. The cable management component is disposed in the outer pipe and in parallel to the shaft core line. The spiral coiled cable unit is reeled on the cable management component. Accordingly, the cable may be stably positioned and the cable may be prevented from rubbing or being tangled with the screw rod.

An electromotive actuator to adjust a height includes an electric motor with a motor shaft, a helical gear assembly operatively connected to the motor shaft, a sleeve-shaped friction brake to act on the motor shaft, and a housing surrounding the electric motor or the helical gear assembly and including a seat of the friction brake. The friction brake includes an opening extending in a radial direction relative to a longitudinal axis of the motor shaft such that the friction brake is attachable to the motor shaft perpendicular to the longitudinal axis.

A cordless height-adjustable instrument table is disclosed. The table includes a plurality of vertical support legs that are equally spaced at each side of a centralized height-adjustment column that is fixedly attached to the bottom portion of the table. The centralized height-adjustment column is fixedly placed above a four-wheel base that is coupled to a motor housing including a charging port, a rechargeable lithium battery pack, and electronic components being provided therein. The table further includes easy touch buttons for raising and lowering the table and a plurality of table extensions that increase the length and width. In practice, the user can actuate the easy touch buttons until a desired height of the table is obtained. A readily available 12-hour rechargeable lithium battery from retailers or manufactures is integrated for prolonged use of the table.

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.

The invention relates to an operating device for a table, having a table panel with an adjustable height and/or inclination and having an internal collision detection device for detecting a collision between the table panel and an object or a person, comprising: a control unit and a hand-held switch that is connected to the control unit and has a display element, on which an element can be displayed for menu navigation, and one or more command buttons, by means of which the height and/or inclination of the table can be adjusted using the menu navigation, wherein at least one of the command buttons is assigned multiple times, and parameters of the table can be adjusted using the command buttons with multiple assignments, said parameters comprising a sensitivity level of the collision detection device.

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.

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods for controlling movement of a desk or table. The apparatuses, systems, and methods may include a housing arranged with the desk or table and a lever configured to initiate raising or lowering of the desk in response to a force applied by a user.
