Abstract

A shoe, in particular a sports shoe, with a shoe upper and a rotary fastener for lacing the shoe on the foot of the wearer by at least one tensioning element, wherein the rotary fastener is arranged on the instep of the shoe and wherein the rotary fastener has a rotatably arranged tensioning roller. In order to improve the fit of the shoe to the foot of the wearer when such central fastener is used, a first tensioning element is arranged, which runs on the lateral side of the shoe upper, and a second tensioning element is arranged, which runs on the medial side of the shoe upper, wherein both tensioning element are fixed by the two ends thereof to the tensioning roller and each form a closed curve on the lateral side or on the medial side of the shoe upper.

First claim

The invention claimed is:

1. A shoe, with a shoe upper, a sole, and a rotary fastener for lacing the shoe on the foot of the wearer by means of at least one tensioning element, wherein the rotary fastener is arranged on an instep of the shoe and wherein the rotary fastener has a rotatably arranged tensioning roller, wherein a first tensioning element is arranged, which runs on a lateral side of the shoe upper, wherein a second tensioning element is arranged, which runs on a medial side of the shoe upper, and wherein each tensioning element has two ends fixed to the tensioning roller and forms a closed curve on the lateral side or on the medial side of the shoe upper, wherein the each tensioning element runs from the tensioning roller to a first deflection element, which deflects the tensioning element in a bottom region of the shoe upper as well as at a location which is arranged in a region between 30% and 42% of the longitudinal extension, measured from a tip of the shoe.

2. The shoe according to claim 1 , wherein the two closed curves of the two tensioning elements on the lateral side and on the medial side of the shoe upper are designed substantially symmetrically to a centre plane of the shoe, wherein the centre plane runs vertically and in longitudinal direction of the shoe.

3. The shoe according to claim 1 , wherein the tensioning roller can be rotated by means of an external electric motor drive.

4. The shoe according to claim 1 , wherein an axis of rotation of the tensioning roller is perpendicular to a surface of the shoe in the region of the instep.

5. The shoe according to claim 1 , wherein each tensioning element runs from the first deflection element to a second deflection element, which deflects the tensioning element in the bottom region of the shoe upper as well as at a location which is arranged in a region between 50% and 60% of the longitudinal extension, measured from the tip of the shoe.

6. The shoe according to claim 5 , wherein each tensioning element runs from the second deflection element to a third deflection element, wherein the third deflection element is arranged in the upper region of the shoe upper adjacent to the rotary fastener.

7. The shoe according to claim 6 , wherein each tensioning element runs from the third deflection element to a fourth deflection element, which deflects the tensioning element in the bottom region of the shoe upper as well as at a location which is arranged in a region between 55% and 70% of the longitudinal extension, measured from the tip of the shoe.

8. The shoe according to claim 7 , wherein each tensioning element runs from the fourth deflection element to a fifth deflection element, which deflects the tensioning element in the region between 33% and 66% of a total height of the shoe as well as at a location which is arranged in a region between 75% and 90% of the longitudinal extension, measured from the tip of the shoe, wherein the tensioning element runs from the fifth deflection element to the tensioning roller.

9. The shoe according to claim 1 , wherein at least one of the deflection elements is designed as a loop which is fixed at the shoe upper and/or at the sole of the shoe.

10. The shoe according to claim 9 , wherein the loop consists of a band which is stitched on the shoe upper and/or on the sole of the shoe.

11. The shoe according to claim 8 , wherein the fifth deflection element encompasses a heel region of the shoe.

12. The shoe according to claim 11 , wherein the fifth deflection element has a V-shaped design with two legs in a side view of the shoe, wherein in the side view of the shoe one of the two legs of the V-shaped structure terminates in the upper heel region and the other leg of the two legs of the V-shaped structure terminates in the bottom heel region.

13. The shoe according to claim 1 , wherein the tensioning elements are tensioning wires.

14. The shoe according to claim 1 , wherein the tensioning elements comprise polyamide or consist of this material.
