DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a shoe fastener which can be actuated via a rotary element with a pulley pivotally mounted in a bearing element coaxially with respect to a central axis of the rotary element for winding at least one cable-like tension element, a reducing gear between the rotary element and the pulley in the form of an eccentric drive in which an external unwinding gear is pivotally mounted in a housing of the shoe closure and which is securable in each of several angular positions.
Such a shoe fastener, with an eccentric gear mechanism, is described in my German patent DE 42 40 916 C1. The outer unwinding toothed wheel is pivoted there in the housing and can be fixed in position by one or more grooves on the circumference.
2. Description of Related Art
Other shoe fasteners are also known, for example from EP 255 869 A2, in which the rope pulley is pivoted in a housing on a stationary steering pivot pin and is driven like a Geneva movement or a planetary gear. The top side of the housing cover is provided with an annular gear which, together with a catch that can be actuated by the turning component, forms a catch device that catches in the closing direction. The turning component has a driving peg that engages in an arc-shaped recess in a washer. The recess extends over a small angle sector so that the turning component is freely movable, relative to the washer, by a small angle of rotation of, for example, 30.degree..
The catch is elastically prestressed on the washer so that a projecting tooth engages in the annular gear and another projecting tooth located on the opposite side engages in another arc-shaped steering recess of the turning component. The steering recess is cut free on one end so that, when the turning component turns in the closing direction, the engaging projecting tooth remains freely movable. When the mining component turns in the closing direction, and after the driving peg strikes within an allocated recess, the washer is also moved. Thus the catch is moved by the annular gear and in doing so catches, by slanted sides, from one tooth to the next.
When the turning component turns in the opening direction, it turns, relative to the washer, according to the clearance angle defined by the recess. In doing so, a ramp-like, rising control surface present on the other end of the steering recess presses the catch, by the allocated projecting tooth, and the catch thus is moved out of the radius of action of the annular gear. Thus the possibility of locking is eliminated and the turning knob can be turned in the opening direction and the rope pulley can be turned, by the gear mechanism, in the unwinding direction. A quick opening of the shoe fastener is thus not possible, despite the relatively expensive construction of the shoe fastener.
Further, shoe fasteners with a turning component are known that have a planetary gear. With these fasteners, a quick disengagement is possible in that, by pressure on the center of the turning knob in the direction of the central axis, the gear mechanism is decoupled from the rope wheel, so that the rope wheel can be freely turned.
SUMMARY OF THE INVENTION
In contrast, with this invention the object to be achieved is to configure a shoe fastener of the above-mentioned type so that a quick disengagement of the shoe fastener and the opening of the shoe with a single actuation component can be performed almost simultaneously.
This object is achieved by the following features: rim; unwinding gear disk and is deflectable transversely with respect to the central axis; that a catch component of the catch element, which points towards the outer catch rim, elastically latches into a groove of the outer catch rim; from the outside for disengaging the catch component from the catch rim; direction when the shoe is opened; and opening direction via the tension element.
In contrast to known quick releases by pressure on a central part of the rotary element, in the quick release design according to the inven
