An actuator system includes a motor having a system of rotating shafts, a conversion arrangement including one of the rotating shafts and converting rotational motion to elongation, and a brake arrangement having one of the rotating shafts as a brake shaft, an electromagnet, at least one brake chamber formed between the brake shaft and an associated brake wall, and a magnetoactive brake member for each brake chamber. Each brake chamber includes a free-wheeling region for receiving the respective brake member. Each brake chamber includes a braking region with a decreasing radial distance between wall and rotation axis. Each brake member is arranged movably in the respective brake chamber in such a way that frictional contact can be formed with the brake shaft and brake wall. In an activated state, the electromagnet is configured to bring each brake member into the associated free-wheeling region.

The multi-height table and chair set is a kit. The multi-height table and chair set comprises a table structure and one or more chair structures. The table structure is a furniture item known as a table. Each of the one or more chair structures is a furniture item known as a chair. The chair is defined elsewhere in this disclosure. The multi-height table and chair set is configured for use with a personal data device. The personal data device remotely controls the elevation of the tabletop of the table structure. The personal data device remotely controls the elevation of the bench of each of the one or more chair structures. The table structure is formed from a master structure. Each of one or more chair structures is formed from the master structure.

A dynamic standing desk having a work surface configured to move with planar motion parallel with the ground and with a range of movement that adjusts as a function of the size of a user of the desk. The desk may include a base, a tabletop that includes the work surface, a frame that movably couples the tabletop to the base, and at least one actuator configured to provide the planar motion. The desk may be used to reduce lower musculoskeletal discomfort of a user of the desk by oscillating the work surface of the desk with a range of movement based on a length of a limb of the user.

A glide bearing for guiding axial movement between inner and outer telescoping columns may include first and second spaced apart contact surfaces, and a resilient wall extending therebetween and having an outer convex surface defining an apex. A span between the apex and a plane defined between the first and second contact surfaces is greater than a width of a space between the outer surface of the inner column and the inner surface of the outer column. The glide bearing is configured to be disposed within the space with the first and second contact surfaces contacting the outer surface of the inner column, with the apex contacting the inner surface of the outer column and with the resilient wall deflecting inwardly toward the plane to accommodate the space in response to a force of the inner surface of the outer column acting against the apex.

The present application relates to a telescopic column (1) comprising a lower part (10) having a first end constituting a first end (4) of the telescopic column, an upper part (20) telescopically moveable relative to the lower part and having a first end constituting a second end (5) of the telescopic column opposite said first end of the telescopic column, a drive mechanism (2) configured to provide telescopic movement between the lower part and the upper part, an cable (30) extending inside the telescopic column, and a cable guiding means (50) coupled to a tensioning device (52) arranged at the second end of the telescopic column. The tensioning device is configured to control the position of the cable guiding means in the telescopic column based on the telescopic extension of the column, and the cable extends through the column via the cable guiding means. The present application further relates to an adjustable furniture (100) comprising at least one telescopic column.

A furniture system includes an elongated chase having a body extending from a first end to a second end. The body has an upper surface and a lower surface. A first leg is coupled to the lower surface of the body and a second leg is coupled to the lower surface of the body and spaced apart from the first leg. Power cables are positioned within a cavity of the body, the power cables configured to connect to a building's power supply. A modular power unit is coupled to the lower surface of the body. The modular power unit includes a power outlet electrically coupled to the power cables.

An electrically adjustable piece of furniture comprises a first and at least one second actuator for adjusting a component of the piece of furniture and a controller for controlling the first and at least one second actuator. The actuators each have a first element and a second element which are displaceable relative to each other, and a sensor attached to the first element and adapted to measure a distance between the first and second elements. The distance measurement is based on a time-of-flight measurement of a wave. The controller is arranged to determine an absolute position of each actuator from the respectively measured distance.

A power-driven table stand with combining mechanotronics includes: a horizontal bar structure (10); a pair of supporters (20), connected at two sides of the horizontal bar structure (10); a pair of vertical post structures (30), connected to each of the supporters (20) and having a motor (31); and an electrical device (40), having a controller (41) and a guide wiring (45), wherein the controller (40) is disposed on the horizontal bar structure (10), the guide wiring (45) is stored and hidden in the horizontal bar structure (10) and each of the supporters (20), and electrically connected to the controller (41) and the motor (31). Accordingly, power wires and signal wires can be effectively and properly stored and hidden.

The invention is about a synchronous lifting mechanism, with a first inner fixed tube and a second inner fixed tube and that the synchronous lifting mechanism has a synchronizing mechanism, the synchronizing mechanism include a first support of which one end is in clearance fit with the inside of the first inner fixed tube and a second support of which one end is in clearance fit with the inside of the second inner fixed tube.
