Abstract:
Device for storing spring energy generated by relative displacement of a stationary retaining element and a mobile runner, which comprises:at least two springs arranged between the retaining element and the runner, wherein a first end portion of each spring is attached to the retaining element, the two springs being biasable in temporal succession, upon relative displacement into a first direction, and being able to release spring energy in temporal succession, upon relative displacement into a second direction opposite to said first direction,a second end portion which is opposite to the first end portion of the spring loaded at a first point in time is immobilized in relation to the retaining element by a first displacement transversal to the direction of the relative displacement in such a way that, during a further relative displacement of said runner in the first direction, no further force is exerted between said runner and said retaining element by said spring loaded at said first point in time, andwherein the immobilized second end portion of the spring loaded at said first point in time, upon relative displacement into the second direction, is connectable to the runner and said spring is enabled to output spring energy during a further relative displacement into said second direction.
