| Abstract: |
In this rotary fastener which can be used particularly on ski boots two traction wire tensioning elements can be altered in their effective length in opposing directions by a rotary movement in one or the other direction in order to tighten or loosen shoe closure flaps. For the accurate adjustment of the rotary fastener and accurate adaptation of the shoe to a foot a ratchet arrangement is provided in the region between the rotary knob and the wire reel for the traction wire tensioning elements and contains an intermediate element which supports a pawl and is rotatable with the rotary knob whilst maintaining a free play as well as a gear ring inserted in a housing cover and is thereby of simple and compact construction.

What is claimed is:
1. In a rotary fastener for a sports shoe such as a ski boot having an upper:
- (a) a housing having a base fixed on said upper;
- (b) a wire reel rotatably mounted in said housing;
- (c) wire tensioning elements extending outwardly of said housing for engagement with closure flaps of the shoe which are to be drawn together;
- (d) drive means rotatably mounted in said housing for driving said wire reel;
- (e) a rotor on said housing rotatable relative thereto and connected to said drive means for rotation thereof to alter the effective length of said wire tensioning elements for selectively tightening or loosening the shoe closure flaps;
- (f) ratchet means between said rotor and said housing including a toothed ring and a pawl, said pawl being engageable with said toothed ring during tightening rotation of said rotor to provide a plurality of locking positions during such rotation and being disengageable during loosening rotation of said rotor as said pawl is pivoted into a release position, the improvement comprising:
- (g) means fixing said toothed ring against rotation and with its teeth facing upward away from said housing base;
- (h) an intermediate ring carrying said pawl for pivotal movement toward and away from said toothed ring and for bodily movement about the axis of rotation of said rotor at a level above said toothed ring and below said rotor;
- (i) spring means for biasing one end of said pawl toward engagement with said toothed ring;
- (j) means for interconnecting said rotor to said intermediate ring for conjoint rotation thereof; and
- (k) means connecting said intermediate ring to said drive means for driving rotation of said wire reel.
