Abstract: Linear actuator (8) comprising a quick release (27) for disengagement of an adjustment element (23) from an electric motor (19) and the part of a transmission (20) extending from the electric motor (19) to the quick release (27), such that the spindle (21) of the linear actuator is rotated under the load on the adjustment element (23). Further, the linear actuator comprises brake means (28) connected to the spindle (21) for controlling the speed of the adjustment element (23), when the quick release (27) is activated. A coupling (34;52,53,54) connected the brake means (28) is configured to set the brake means (28) in an active state, when the coupling (34; 52,53,54) is engaged, or in an inactive state, when the coupling (34;52,53,54) is slipping or disengaged.

Abstract: Control unit (7), especially for a patient lift (1) comprising a base (10) and a power supply (8), said power supply (8) is releasably mounted on the base (10), and comprising locking means for retaining the power supply (8) on the base (10). The locking means comprises a set of slots and protrusions (17,18;20,22) on the base (10) and the power supply (8) and where the protrusions and slots engage each other, when the base (10) and the power supply (8) is displaced sideways in relation to each other. A tab (27) is arranged on an arm (24) of the locking handle (23). The tab (27) goes into the gap (28) between the base (10) and the power supply (8), when the locking handle (23) is locked. Thus, the protrusions (17,20) and slots (18,22) are in engagement with each other and at the same time functioning as a locking mechanism.

Abstract: The present invention relates to a linear actuator comprising a console (2), an outer tube connected to the console, an electric motor, a transmission, and a spindle in connection with the transmission. The linear actuator comprises a spindle nut on the spindle and an inner tube connected to the spindle nut. The spindle nut and the inner tube are guided inside the outer tube. For mounting the linear actuator, a rear end is equipped with a rear mounting (5) and a front end of the inner tube is equipped with a front mounting. In such a linear actuator the rear mounting should be mounted to the housing in a simple manner. To this end, the console (2) comprises a first fixing geometry (18) having a number of first fingers (19) distributed in the circumferential direction around the axis and the rear mounting (5) comprises a second fixing geometry (20) as negative form of the first fixing geometry, wherein the first fixing geometry and the second fixing geometry form an overlapping region.
