Abstract
The object of the invention is to improve a central closing device for shoes with a rotationally supported cord disc for at least one cord-type tensioning member for closing the shoe in such a way that the number of rotations of the cord disci is limited without any increasing the space required. This object is achieved by the fact that both the cord disc (3) and a stationary member (1 or 41) each have mutually-cooperating tooth profiles (41a, 42a or 41b, 42b) having the same tooth pitch but of different diameters. Located in the intermediate space (49) created due to the different diameters of the tooth profiles (41a, 42a or 41b, 42b) is an idling pinion (43) of the same pitch, which meshes with the two tooth profiles (41a, 42a or 41b, 42b). At least one stop (46, 46') is provided to limit the travel of the idling pinion (43).
Claims16
Central closure for shoes with a rotatably mounted sheave for at least one ropelike tightening element for closing the shoe, in which the sheave is coupled to a gear by an actuating element and can be driven via the latter and the number of revolutions of the sheave can be limited by a stop, characterized in that both the sheave and an immovable part each comprise a toothing with the same tooth pitch that are effectively connected to one another, are arranged coaxially to one another, but have different diameters, in that a gap is created between the toothing of the sheave and the toothing of the immovable part by the different diameters thereof, a gearwheel that meshes with the two toothings is arranged in a freewheeling manner with the same tooth pitch is located in said gap, and in that at least one stop is located in said gap within a path of travel of the freewheeling gearwheel for limiting the travel thereof.
