Abstract
The invention relates to a linear actor arrangement, comprising a linear actor with two ends whose distance is variable depending on an energizing of the linear actor, wherein each end is attached to a respective first or second coupling element which engage a coupling surface, wherein the coupling surface and the coupling elements exhibit mating surface structures in such a manner that the coupling elements are prevented from moving in a direction while being allowed to move in an opposite direction.
Claims14
A linear actor arrangement, comprising:
- a coupling surface;
- and
- a linear actor comprising a first end and a second end,
- wherein a distance between the first end and the second end of the linear actor is variable depending on an energizing of the linear actor,
- wherein the first end and the second end of the linear actor are respectively attached directly to first and second coupling elements that engage the coupling surface in a manner such that the first and second coupling elements are spaced apart from each other during expansion and contraction of the linear actor according to the energizing of the linear actor,
- wherein the coupling surface and the first and second coupling elements comprise complementary mating surface structures that prevent the first and second coupling elements from moving in a first direction while allowing the first and second coupling elements to move in a second direction, the second direction opposite to the first direction,
- wherein each complementary mating surface structure is a micro saw tooth structure comprising a plurality of teeth, and
- wherein the linear actor has an adjustment range that is greater than a distance between two consecutive teeth of the plurality of teeth of the saw tooth structure.
