Device for activating a lace-up traction device for a shoe

A device for activating a lace-up traction device for a shoe, comprising a housing arranged in the rear region of the substructure of the shoe, with a slider comprising a rearward projecting activation projection being accommodated in said housing so as to be slidable in longitudinal direction of the shoe;

• said device further comprising a tension lever encompassing the housing, said tension lever being held at its front end so that he can hinge up or down and said lever being able to be pushed down by the heel of the foot when the shoe is put on;
• with said tension lever in its pushed down state being lockable with the slider which has been brought to a rearward snap-in position, and unlockable by moving the slider forward;
• and with the underside of said tension lever comprising a guide for the top end region of a rocker whose bottom end region acts together with lace-up traction elements and is guided in a longitudinal guide, which rocker being pre-tensioned in the direction of hinging forward and upward by means of a spring arrangement, whereby the guide of the tension lever, said guide being associated with the upper end region of the rocker which is a single-part lever, comprises two branches arranged at an angle in relation to each other;
• whereby the slider comprises a stopping face, and the rocker comprises an engagement element which when the tension lever is pushed down engages said stopping face, which results in the slider being slidable to the rear, into the rear snap-in position associated with the snap-in device of the tension lever;
• and whereby the slider comprises a link-type guide means, which guide means is open towards the front, while the rocker comprises an engagement element which, by moving forward the slider, can be made to engage with said guide means when the tension lever is pushed down;
• with said action resulting in the engagement element of the rocker, which engagement element engages the angled guide of the tension lever, to be able to be moved to a position which is suitable for moving into the front branch of the angled guide of the tension lever.
