Abstract
In this rotary closure according to the invention for a sports shoe a traction cable arrangement for drawing together the shoe closure flaps can be wound onto and unwound from a rotatable cable pulley. The traction cable arrangement consists of one single traction cable, and coaxially with the cable pulley a stop element is provided and rotatably mounted in such a way that the cable pulley can carry out a maximum of up to approximately two revolutions in one direction of rotation. In this way a particularly compact rotary closure is produced with reliable security against over-rotation of the cable pulley.
Claims15
A rotary closure for a sports shoe having closure flaps that may be drawn together to close a foot-accommodating opening and secure the shoe to a person's foot, said closure comprising a housing mounted on the shoe at one side of said opening;
- a cable pulley rotatably mounted in the housing;
- a cable having one end thereof attached to said pulley and its other end attached to said shoe on the opposite side of said opening;
- means for rotating said pulley in opposite directions to wind or unwind the cable on or from the pulley;
- stop means mounted in said housing for rotation relative to said housing and said pulley;
- entrainment stop means carried by said pulley for rotation therewith and occupying a position to engage and entrain said stop means in response to rotation of said pulley relative to said stop means and effect rotation of said stop means conjointly with said pulley in response to further rotation of said pulley following engagement of said stop means by said entrainment stop means;
- and limit means in the path of rotation of said stop means for limiting rotation thereof by said entrainment stop means.
A rotary closure for a sports shoe having closure flaps that may be drawn together to secure the shoe to a person's foot, said closure comprising a housing mounted on the shoe;
- a cable pulley mounted in said housing for rotation about an axis;
- a cable having one end thereto attached to the cable pulley and its other end fixed to the shoe;
- a journal pin having a central axis coincident with the axis of the pulley;
- a stop mounted beneath the cable pulley for pivotal movement about the central axis;
- end surfaces on the housing operable to limit pivotal movement of the stop about the central axis;
- an entrainment stop on the cable pulley engageable with the stop and operable to limit movement of the cable pulley about the central axis to about two revolutions;
- a planetary gear set connected between the central journal pin and the cable pulley;
- a rotary knob attached to the central journal pin for actuating the planetary gear set to drive the cable pulley in a direction to wind the cable on said cable pulley;
- and a ratchet mechanism operable to prevent the cable pulley from rotating in a direction to unwind the cable from said cable pulley when the ratchet mechanism is activated and which can be deactivated to allow the cable pulley to rotate and unwind the cable.
