Abstract (en)
[origin: WO2017059876A1] The invention relates to a shoe (1), in particular an athletic shoe, having a shoe top (2) and a rotary closure (3) for lacing the shoe (1) on the foot of the wearer by means of at least one tensioning element (4, 5), wherein the rotary closure (3) is arranged on the instep (6) of the shoe (1), wherein the rotary closure (3) has a rotatably arranged tension roller (7), wherein the rotary closure (3) is driven by means of an electric motor (8), and wherein the transfer of the rotational motion of the electric motor (8) to the tension roller (7) occurs via a transmission (9). In order to achieve a compact design which provides sufficiently high torques for the lacing, according to the invention, the transmission (9) has: a first spur gear stage (10), wherein a spur gear (11) of the first spur gear stage (10) intermeshes together with a drive pinion (12) of the electric motor (8) and wherein a pinion (13), connected to the spur gear (11) of the first spur gear stage (10) in a rotationally fixed manner, intermeshes with a spur gear (14) of a second spur gear stage (15), a second spur gear stage (15), wherein the spur gear (14) of the second spur gear stage (15) is connected to a worm (16) of a worm gear (16, 17) in a rotationally fixed manner, a worm gear (16, 17), wherein the worm (16) intermeshes together with a worm gear (17), wherein the tension roller (7) is connected to the worm gear (17) in a rotationally fixed manner.
