Turning fastener for a shoe

Abstract

A turning fastener for a shoe has a pulling means with two end portions, which act on a take-up reel, which is provided with an annular groove for receiving the pulling means, a rotatable mounting of the take-up reel with a bearing journal, which engages in a bearing, a holder, which can be fastened to the shoe, for the rotatable mounting, and an engageable and disengageable directional locking mechanism, which in the engaged position blocks the take-up reel in one direction of rotation for closing the shoe and in the disengaged position releases it in this direction of rotation. The take-up reel is formed as a rotary grip, wherein two through-openings, extending from the annular groove to the end face of the take-up reel that is facing away from the holder, are provided for leading one or the other end portion of the pulling means through. The take-up reel is guided in an axially displaceable manner with the bearing journal and the bearing, and the directional locking mechanism is engaged in the position of the take-up reel in which it is pushed towards the holder and is disengaged in the position in which it is pushed away from the holder.
