Patent ID: 8430385

Claim:
A wedge drive comprising a slider element receiving component, a movable slider element and a driver element, wherein a dovetail shaped guide is provided between the slider element and the slider element receiving component, wherein the slider element comprises an upper portion and a lower portion connected at a narrowing neck portion to form a dovetail shaped configuration, the slider element including sliding surfaces comprising a first sliding surface associated with the lower portion at a first angle inclined downwardly relative to an axis perpendicular to a plane along the narrowing neck portion and a second sliding surface associated with the upper portion at a second angle inclined upwardly relative to the axis, by way of which forces are transmitted from the slider element receiving component to the slider element in a working stroke during which the slider element is moved outwardly between the driver element and the slider element receiving component, and the slider element receiving component has a corresponding counterpart portion including sliding surfaces facing the sliding surfaces associated with the slider element, wherein the dovetail shaped configuration and the counterpart portion together form the dovetail shaped guide, and the dovetail shaped configuration of the slider element extends between outwardly protruding portions of the corresponding counterpart portion of the slider element receiving component, wherein said protruding portions comprise the sliding surfaces which face the sliding surfaces associated with the slider element, by way of which forces are transmitted from the slider element receiving component to the slider element in the working stroke.
