Shoe closure mechanism with a rotating element and eccentric driving element

Shoe closure mechanism comprising a housing part, a rotating element that closes a top side of the housing part, a cable pulley coupled with the rotating element by an eccentric driving element, the cable pulley being located in a housing part having a bottom wall and an axially projecting peripheral edge, an eccentric drive peg coupled with the rotating element and centrally engaged in an eccentric driving disk that has outer gearing, and is rotatably mounted to move parallel to the cable pulley, the cable pulley having drive pegs on it that engage in circle openings of the eccentric driving disk, coupling the cable pulley with the eccentric driving disk, and with a pivoted rolling disk having an inner gearing lying parallel to the cable pulley and on which the outer gearing of the eccentric driving disk can roll, and with at least one recess on the periphery of the rolling disk in which a fixing element can engage and secure the rolling disk against rotation, wherein the rolling disk lies on the bottom wall of the housing part;

• wherein the rolling disk is a flat, narrow ring, an inner face of which forms the inner gearing and an outer face of which forms a rotatable guide path with an inner wall of the peripheral edge of the housing part;
• wherein the eccentric driving disk lies on said bottom wall inside an open space of the rolling disk in the same plane therewith;
• wherein the cable pulley lies on the rolling disk and the eccentric driving disk;
• wherein the cable pulley is pivoted centrally on a section of an axle unit;
• wherein the eccentric driving disk has a central hole by which it is rotatably mounted on an eccentric driving peg that projects axially from the axle unit;
• wherein a bearing peg is centrally located with respect to an axis of rotation, projecting from the eccentric driving peg into a bearing hole of the housing part;
• wherein a driving projection projects from the axle unit, on a side opposite said eccentric driving peg and bearing peg, into a hole of the rotating element;
• wherein the driving projection is rigidly coupled with the, rotating element;
• wherein at least one opening that aligns with recesses of the rolling disk is provided in the housing part;
• and wherein a fixing pin of a spring clip is engagable with the recesses of the rolling disk via at least one opening of the housing, the fixing pin being provided with pulling means for enabling it to be pulled outwardly relative to said recesses.
