Abstract

An athletic shoe, having a shoe upper and a rotary closure for lacing the shoe on the foot of the wearer by at least one tensioning element. The rotary closure is arranged on the instep of the shoe. The rotary closure has a rotatably arranged tension roller and is driven by an electric motor via a transmission. The transmission includes a first spur gear of the first spur gear stage that meshes with a drive pinion of the electric motor, a pinion, connected to the first spur gear in a rotationally fixed manner, that meshes with a second spur gear of a second spur gear stage, wherein the second spur gear is connected to a worm of a worm gear, and the worm meshes with a worm wheel.

Claims

1. A shoe, having a shoe upper, tensioning elements including a first tensioning element and a second tensioning element, and a rotary closure for lacing the shoe on the foot of the wearer by the tensioning elements, wherein the rotary closure has a rotatably arranged tension roller, wherein the rotary closure is driven by an electric motor, and wherein the transfer of the rotational motion of the electric motor to the tension roller occurs via a transmission, wherein the transmission comprises:

a first spur gear stage, wherein a spur gear of the first spur gear stage meshes with a drive pinion of the electric motor and wherein a pinion is connected to the spur gear of the first spur gear stage in a rotationally fixed manner,

a second spur gear stage with a spur gear, wherein the spur gear of the second spur gear stage meshes with the pinion of the first spur gear stage,

a worm gear with a worm connected to the spur gear of the second spur gear stage in a rotationally fixed manner, wherein the worm meshes with a worm wheel, wherein the tension roller is connected to the worm wheel in a rotationally fixed manner, wherein the rotary closure is arranged at an instep region of the shoe,

wherein the first tensioning element runs on the lateral side of the shoe upper and wherein the second tensioning element runs on the medial side of the shoe upper, wherein each of the tensioning elements has two ends fixed at the tension roller, wherein the first tensioning element forms a closed curve at the lateral side of the shoe upper and wherein the second tensioning element forms a closed curve at the medial side of the shoe upper, and

wherein each of the tensioning elements runs from the tension roller to a first 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 the region between 30% and 42% of a longitudinal extension, measured from the tip of the shoe.

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

3. The shoe according to claim 1, wherein the axis of rotation of the electric motor is arranged horizontally and transversal to the longitudinal extension of the shoe.

4. The shoe according to claim 1, wherein the first spur gear stage has a low geared ratio between 1:

4 and 1;

6.

5. The shoe according to claim 1, wherein the second spur gear stage has a low geared ratio between 1:

3 and 1;

5.

6. The shoe according to claim 1, wherein the electric motor is connected with a battery, wherein a limiting element is arranged between battery and electric motor by which the supply current for the electric motor can be limited to a maximum value.

7. The shoe according to claim 6, wherein the battery being rechargeable can be supplied with a charge current via an induction coil.

8. The shoe according to claim 1, wherein both curves of both tensioning elements at the lateral side and at the medial side of the shoe upper are designed substantially symmetrically to a center plane of the shoe, wherein the center plane is arranged vertical and along the longitudinal extension of the shoe.

9. The shoe according to claim 1, wherein the each of the tensioning elements 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 the region between 50% and 60% of the longitudinal extension, measured from the tip of the shoe.

10. The shoe according to claim 9, wherein the each of the tensioning elements 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 closure.

11. The shoe according to claim 10, wherein the each of the tensioning elements 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 the region between 55% and 70% of the longitudinal extension, measured from the tip of the shoe.

12. The shoe according to claim 11, wherein the each of the tensioning elements runs from the fourth deflection element to a fifth deflection element, which deflects the tensioning element in a region between 33% and 66% of the total height of the shoe as well as at a location which is arranged in the region between 75% and 90% of the longitudinal extension, measured from the tip of the shoe, wherein the each of the tensioning elements runs from the fifth deflection element to the tension roller.

13. A shoe according to claim 1, wherein the shoe is an athletic shoe.
