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: An apparatus for adjusting the height of a base cabinet having a table top thereon includes a bottom plate supporting a lifting assembly, the lifting assembly including a spindle unit with a spindle and a spindle nut mounted on the bottom plate, an upper end of the spindle unit providing a carrying surface, and a single electric motor for driving the spindle unit.

Abstract: A linear actuator especially for adjustable furniture comprises a spindle (16) with a spindle nut (16a) for bringing about the adjustment of the article of furniture. At the end of the spindle (16) there is a bearing (17) for mounting of this in the actuator. The spindle/spindle nut (16,16a) is driven by an electric motor (27) through a transmission (28). For preventing accidents and/or damage during the adjustment of the article of furniture the actuator is equipped with a squeeze protection based on a piezo element (22). This piezo element (22) is arranged in connection with the bearing (17) for registering the forces or deflections of the forces affecting the spindle (16). In that the piezo element (22) has a through-going hole for the spindle the mounting of the piezo element (22) is simplified and further it has turned out that a particularly good signal/noise ratio is obtained.

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 linear actuator (8) in which a squeeze protection device is arranged, where the device is located in connection with the rear fixture (17) on the motor (10). The squeeze protection device is based on a piezo element (23), which as a module (22) is built into the actuator (8), so that it is passed through by the forces, exerted by the actuator (8). The piezo element (23) is equipped with cables (30), which are connected to a printed circuit board (31) in the actuator (8), where the connections for the actuator (8) are collected, so that the signal from the squeeze protection in an easy manner may be communicated to a control device (6), which can stop the motor (10) or briefly reverse the direction of the movement and thus release a trapped object.

Abstract: Gear, preferably for actuators of the type, where an electric motor (1) through the gear drives an activation element, such as a pivotal arm or a longitudinally movable element, and where the gear has at least two gearing stages. The first stage is constituted by a worm drive with a worm—(11; 13a, 13b) and the subsequent gearing stage is constituted by a crown and bevel wheel (23; 16a, 16b). The crown wheel faces towards the worm drive and has a power take-off (24, 27) in extension of or in all essentials in extension of the worm (11) or parallel thereto. The bevel wheel (16a, 16b) is with its axis of rotation arranged perpendicular in relation to the axis of rotation of the worm (11), and the worm wheel (13a, 13b) is in drive connection with the bevel wheel (16a, 16b) through a gear train (14a, 15a; 14b; 15b). Thus a relatively compact transmission with a high gearing is achieved, and by having worm wheels, toothed gearing and bevel and crown wheels of plastic the transmission is in addition silent.

Abstract: Height-adjustable work table, preferably kitchen table, comprising at least one cabinet (1) on top of which a table top is located. The cabinet(s) (1) is located on a number of electrically driven height-adjustable platforms (2). In that the platforms (2) are mutually retained by at least one connection rail (14) 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 (4) is placed. This toe kick (4) is telescopic in height such that the toe kick (4) regardless of the adjusted height of the kitchen table shuts off access under the cabinet. The connection rail (14) may constitute an element of the telescopic toe kick (4).

Abstract: In lifting columns (1) for tables and similar articles of furniture and consisting of pipe profiles (2a, 2b) with intermediate slides (8), it is a problem that the profiles (2a, 2b) have relatively great dimensional tolerances. This means that the gap between two successive sections may vary relatively much, which causes a great play in the column. This is solved in that at least one of these sections (2a) at one of the slides (8) is formed with a local deformation of the wall inwards toward the slide to press the slide inwards against the following section (2b). The dimensional tolerances may be neutralized by suitable arrangement and selection of deformations as well as the force with which the deformation is made.

Abstract: An actuator for beds, slatted beds or chairs of the type accommodating, in a cabinet, two drive units based on a spindle and a spindle nut configured as an adjustment element, cooperating with an arm of a rotary shaft for a backrest section and a legrest section, respectively, in the bed, the mattress support or the chair. The two spindles are rotational interconnected and are driven by a common reversible electric motor. By having just one motor and one transmissions, as well as no switching mechanism between the two spindles, a simple and inexpensive structure is provided.
