Embodiment Construction

[0102] Figure 1 to Figure 4 A front view of an actuator according to an embodiment of the invention is shown. The actuator 1 comprises a housing 2 consisting of an upper housing shell 3 and a lower housing shell 4 . The housing shell may be made of plastic or metal by suitable casting or molding techniques. The housing 2 is also provided with a number of attachment points 5 for connecting the housing 1 to other equipment. The attachment point is preferably provided with a threaded recess.

[0103] The actuating rod 6a formed by a plurality of links (as will be described in detail below) can be fully retracted into the housing 2, as figure 1 shown in , and through a series of intermediate positions - one such as figure 2 Shown - extends from housing to image 3 Fully extended position shown in . An electrical cable is connected to the housing to power the electric drive motor, which will be described in more detail below. In this embodiment, the housing 2 is a flat cub...

Abstract

An actuator comprises a plurality of chain links that can be wound up to transform a chain of the links into a stable elongated rod protruding from the actuator and can be unwound to transform the elongated rod into a chain that is received in a chain magazine. The actuator is particularly compact and flat and can be placed in the relatively narrow spaces.

Description

technical field [0001] The present invention relates to an actuator, in particular to an actuator having a very low build height in terms of actuation correction. Furthermore, the application concerns a chain for such an actuator, in particular a chain capable of changing from a chain to a rod and vice versa. Background technique [0002] WO99 / 53221 discloses a method and apparatus for transferring compressive and / or tensile loads. The device comprises a chain with a plurality of links rolled up to interlock and form a shaft, and vice versa. [0003] It is known to provide a shaft member which is made resistant to compressive and / or tensile loads and to the helical coil through winding guides connected to one of the two objects and to the drive. High stiffness and stability under bending and torsional loads caused by winding interlocking links under axial displacement in winding. In addition, there is provided a coupling member for a helically wound connection with the ot...
