Positioning device for an adjusting means, in particular a shoe

The invention relates to a positioning device (1) for releasably securing at least one position of a relative, approximately linearly, to one with a structure (45), z. As a shoe fixed to the actuating means, adjustable actuating means (3) which supports at least one adjustable coupling means (9) by the action of a spring arrangement (39) in a position of the adjusting means (2, 3) to each other fixing position into a coupling mount (20) of the structure (45) actuating means (2) connected in engagement. The coupling agent (9) is mounted in the adjustable means (3) in perpendicular to a direction of adjustment of the adjusting means (3) direction of linearly displaceable and in a position between the adjusting means (2, 3) fixing position with a coupling extension (21) with the coupling receptacle (20) of the structure (45) actuating means (2) connected and disposed in an adjustable adjusting means (3) positioning seat (42) in engagement.
