Abstract
A coupling device for linear drives for linking a drive part performing a linear movement in an axial direction with a guide part guided for longitudinal movement on a longitudinal guide parallel to the direction of movement. A force input part connected with the drive part and a force output put part connected with the guide part are provided, the force input part and the force output part being coupled together kinetically by means of an intermediately placed link member. As a link member and a elongated or longitudinal spring member is provided which is able to be bent in at least one transverse direction in a resiliently elastic manner and is non-yielding in its longitudinal direction, said spring member being aligned at least substantially in the axial direction. It is secured at a first connection point to the force input part and at a second connection point spaced from the first connection is connected with the force output part, in each case non-movably in the axial direction.
