Abstract: An actuator system comprising a housing (2, 19) having at least one socket (6) for the insertion of an electrical plug (7). The housing (2, 19) is provided with an arrangement which is capable of retaining an electrical plug, preferably of the Jack, DIN or Minifit type, inserted into said socket, said arrangement comprising a union nut (8) which may be retained in a position above the opening of the socket (6), and which at the same time surrounds the plug (7), said union nut (8) being rotatable between an inoperative position in which the plug (7) may freely be inserted and removed, and another position which is a locked position, in which the plug (7) cannot be inserted and, if it is already inserted, cannot be removed.

Abstract: Actuator system comprising at least one actuator, a control unit, a power supply and an operations panel, where the actuator in a transmission between an activation element (4) and a reversible electric motor is inserted a quick release unit (13) for release of the activation element (4) from the electric motor and the part of the transmission between the motor and the quick release. The actuator comprises at least one electrical switch (30), activated with the quick release. The signal from the electrical switch(es) (30) may be used for various purposes, such as triggering a power supply from sleep mode, activating one or more actuators, or activating an external function such as an alarm etc.

Abstract: Actuator comprising of a quick release unit and a means for determining the position of an activation element. With the quick release unit it is possible to release the activation element from the actuator's electric motor and the transmission or, at least part of it, to make a rapid adjustment to the activation element without the motor and transmission. The means typically used for determining the position of the activation element comprises of a potentiometer, an optical or magnetic encoder indirectly driven by the motor. By connecting the instrument for position determination (33) to the spindle (2) or the part of the transmission between the quick release and the spindle (2), the position of the activation element remains known regardless of whether it is released or connected, or has been released.

Abstract: A linear actuator comprising a spindle (5) with a spindle nut (6), where the spindle (5) is driven by an electric motor (2) via a transmission (3,4), comprising a planetary gear (4). The construction is constructed in such a way that the spindle (5) is lead through the transmission (3,4) and is embedded by means of a ball bearing (20) in connection with a rear mounting (10), causing the axial forces to be lead through the transmission (3,4) via the spindle (5) and the ball bearing (20) to the rear mounting (10). This means that the construction is simpler and less voluminous and that the axial forces, moreover, are not transferred to the transmission.

Abstract: A linear actuator comprising a cabinet (1), an electric motor (2), a transmission (4), a gear housing (11), a spindle nut (6), a spindle (5), the actuator being furnished with an opening (20) in the gear housing (11), where a gear wheel power take-off (21) is accessible and may be equipped with optional equipment. The gear wheel power take-off (21) is constructed as a tooth gearing on a planetary wheel holder (16) in a planetary wheel and transfers a movement to the optional equipment, which is proportional to the movement of the spindle nut during its travel on the spindle.

Abstract: Linear actuator (1) comprising an electric motor connected to a spindle via a transmission, on said spindle is mounted a spindle nut secured to an activation element (2), said activation element (2) being equipped with a front attachment (3). The actuator (1) is further furnished with a rear attachment (4), which is axially displaceable between defined stops. The rear attachment (4) activates a switch (7) in at least one of the displaceable positions of the rear attachment (4).

Abstract: A lifting column comprising a number of telescopic members and a drive unit for extension of the members located internally herein. The column is intended for hospital and care beds of the art comprising a column at each end in its longitudinal centre plane and connected to the lower frame (1) and the upper frame (2) respectively so that the height of the upper frame can be adjusted by activating the drive unit of the lifting columns. This drive unit is a scissor mechanism constructed as a separate unit with two identical interconnected scissors (6, 7) located between a bottom and top element (8, 9) and by the longitudinal edges of these plates. A linear actuator (18) is, with its one end, secured to one of the bottom and top element and the other end secured to an interconnection element (16) between the two scissors. The scissor mechanism hereby becomes particularly rigid and the telescopic members can thus be constructed as a simple enclosure without stability.

Abstract: The present invention concerns a lifting device which is configured to be coupled mechanically to a given telephone apparatus, said telephone apparatus having a handset and a fixed part, and whereby the lifting of the handset activates a switch in the telephone apparatus. The lifting device comprises a movable element which is configured to be in connection with the handset and lift the handset by means of a drive unit which brings about a movement of the movable element. The lifting device also comprises a bracket which is configured to be placed on the telephone apparatus in between this and the handset, under which the movable element is housed in a movable manner in the bracket.
