摘要

Device for tensioning springs comprises a round shaft (1) on which a pressure spring (2) is held via a rod (7). The pressure spring is guided via a sliding bearing (4, 5) between the shaft and an outer-lying guide path (3) arranged next to the shaft so that the distance between the guide path and the shaft becomes shorter as the shaft rotates. Preferred Features: The sliding bearings are preferably roller bearings. The guide path preferably has the form of a parabola and is made of an elastic material, preferably spring steel.
