Abstract: Linear actuator comprising a housing (1) with an electric motor (6), which through a transmission (12) drives a spindle (10) with a spindle nut (13). To the spindle nut (13) is secured a tubular adjustment element (3), which is guided in a guide tube (2). A bushing (15) is secured at the rear end of the guide tube (2) by means of which the guide tube (2) is secured to the chassis (7) of the actuator. Expediently, the securing is done with stampings (16) from the outer side of the mounting bushing (15) and into the guide tube (2). These stampings (16) are appropriately done opposite channels, such as screw channels (17) in the guide tube (2), such that the stampings (16) are received in the channels and moreover do not in a disrupting manner protrude into the guide tube (2) and prevent the movement of the spindle nut (13) and the adjustment element (3), respectively.

Abstract: Linear actuator comprising an electric motor (6), which through a transmission (12) drives a spindle unit comprising at least one spindle (10) with a spindle nut (13). A tubular adjustment element (3) in connection with the spindle unit is displaced either outwards or inwards depending on the direction of rotation of the spindle unit. A brake in the shape of a coil spring (21) is arranged in connection with a cylindrical element (15) for retaining the tubular adjustment element (3) in a given position when the power for the electric motor (6) is cut off. The cylindrical element (15) is designed as a separate cylindrical element arranged on the spindle (10) or a shaft in the transmission (12). The separate cylindrical element (15) is preferably arranged on a rear end of the spindle (10) between the rear mounting (4) and the bearing (11) for the spindle (10).

Abstract: Electric actuator system preferably for furniture, especially beds such as hospital, care or domestic beds comprising at least one actuator (6, 7; 21) for bringing about the adjustment of the article of furniture, a mains-based power supply (26, 31) and typically also a rechargeable battery pack, a controller (25;32), at least one operating unit (14, 29) and an orientation light (16). The actuator system is equipped with at least one socket (15) for a plug, and the orientation light (16) is designed as a separate unit with a plug (17) for cooperation with the socket (15) or one of the sockets in the actuator system. Hereby, a simplification of the structure of the actuator system and great flexibility with regard to equipping the actuator system with an orientation light (16) is achieved. Further, it becomes simple to replace the orientation light (16) in case it breaks or a different light intensity or color is desired.

Abstract: An electrical actuator system for adjustable furniture, in particular height-adjustable tables (1), comprising at least one linear actuator (4), at least one operating unit (22) and a control box (12). By arranging therein at least one connector for cables into mutually opposing wall sections of the control-box cabinet for connection of linear actuators with cables, great simplification of the connection of the linear actuators to the control box is achieved, as when an uncoupling has been omitted, when the actuators have been wrongly connected during assembly, or if an actuator falls apart.

Abstract: A telescopic lifting column (1) preferably for furniture, such as height adjustable tables and beds, and comprising at least two mutually telescopic members (2, 3, 4) and an electric drive unit (5, 10; 41, 42) for adjusting the telescopic members. The lifting column comprises a telescopic cable guiding device (22; 45, 58, 80, 103) for guiding at least one electric cable (29), where the telescopic cable guiding device extends between or in all essentials between the lower and upper end of the lifting column and is connected thereto so that the telescopic cable guiding device collaborates in the telescopic adjustment of the lifting column. Thus the cables may be guided in a protected manner.

Abstract: Height-adjustable work table, preferably kitchen table comprising at least one cabinet on top of which a table top is located. The cabinet(s) is located on a number of electrically driven height-adjustable platforms. In that the platforms are mutually retained by at least one connection rail these appear as stable both during the assembly of the work table and of the assembled table. Between a surface, typically a floor on which the platform is located, and an underside of the cabinet a toe kick is placed. This toe kick is telescopic in height such that the toe kick regardless of the adjusted height of the kitchen table shuts off access under the cabinet. The connection rail may constitute an element of the telescopic toe kick.

Abstract: A combination of an articulated apparatus having an electromechanical actuator, a power supply and a control unit with a unique electronic address, and a cordless controller, the cordless controller becoming exclusively electrically paired to the articulated apparatus when common signals therefrom to the control box include the unique electronic address, thus enabling control of the articulated apparatus when located near the other apparatus having other electronic addresses.

Abstract: Bed, comprising a lower frame (1) and an upper frame (2) with a supporting surface for a mattress, and where the upper frame (2) is connected to the lower frame (1) so that the upper frame can be raised and lowered in proportion to the lower frame by means of one or more adjusting means (5, 6) driven by an electric motor. In order to prevent squeezing between the upper and lower frame when the upper frame is lowered, the bed is provided with anti squeezing means. These comprise a light source and a receiver positioned in a corner of the lower frame. The light source sends a light beam which follows the lower frame all the way around and runs just above the top side of the lower frame. When the light beam is interrupted the control unit reacts by cutting off the current for the motors.

Abstract: A lifting column, preferably for height-adjustable tables comprises a guide with three mutually telescopic members (1,2,3) and a motor driven spindle unit for bringing about the movement. The second member (2) of the guide is with a lower end secured to a lower end of the second spindle (6). The second spindle nut (8) co-operating with the second spindle (6) is with a bearing (18) with a rigid connection (28) fixed to a shaft stub (16) secured to an upper end of a drive tube (9). The shaft stub (16) is via a second bearing (20) secured to a mounting plate (23), by means of which the spindle unit is secured in the lifting column. Thus, the vertical load on the lifting column is led through the spindle unit around the guide (1,2,3). This enables a better and more optimum dimensioning of the guide (1,2,3) and the spindle unit, just as it is advantageous in terms of assembly and not least it enables a better implementing of a squeeze protection in the lifting columns.

Abstract: A communication system for exchanging data between an actuator system and an external device, e.g. an operation where the communication system in the form of a gateway and a codex interprets the information in the bidirectional data stream and communicates the information on both sides. The communication system is furthermore provided with an RFID circuit integrated in a handset. The RFIC circuit can communicate information about the gateway's unique identification, also known as an MAC-address. This achieves easy connection of an external device to the actuator system without having to enter data manually.
