Abstract

L'invention concerne un dispositif de serrage de corde. Le dispositif de serrage de corde est caractérisé en ce qu'il comprend : un boîtier comprenant une surface supérieure ouverte; une bobine qui est agencée rotative à l'intérieur du boîtier, qui présente une forme annulaire plane, et qui est conçue pour serrer une corde lorsqu'elle est tournée dans un premier sens et pour relâcher la corde lorsqu'elle est tournée dans un second sens; une poignée tournante agencée sur le boîtier de sorte à recouvrir la surface supérieure ouverte du boîtier et qui est accouplée rotative au boîtier; un bouton de commutation de rotation présentant la forme d'un cylindre ou d'une broche, le bouton de commutation de rotation pénétrant verticalement dans la partie centrale de la surface supérieure de la poignée tournante de sorte à pouvoir s'élever et s'abaisser, la partie d'extrémité supérieure du bouton de commutation de rotation étant reliée à la poignée tournante de sorte à pouvoir tourner conjointement avec la poignée tournante, et la partie d'extrémité inférieure du bouton de commutation de rotation étant accouplée à la bobine de sorte que, lorsqu'elle est tournée dans le premier sens conjointement avec la poignée tournante, la bobine puisse tourner; un ressort élastique agencé sous le bouton de commutation de rotation de sorte à mettre sous pression le bouton de commutation de rotation vers la poignée tournante, le ressort élastique étant conçu de sorte que, lorsque le bouton de commutation de rotation reçoit une pression et s'abaisse, le ressort élastique se contracte et, lorsque le bouton de commutation de rotation est libéré de la pression, le ressort élastique revienne en place; et un moyen de séparation agencé au sien du boîtier de sorte à être positionné sous le bouton de commutation de rotation et conçu de sorte que, lorsque le bouton de commutation de rotation s'abaisse puis s'élève du fait d'une opération de pression de bouton qui fait pression sur le bouton de commutation de rotation, le moyen de séparation soit relié au bouton de commutation de rotation et sépare le bouton de commutation de rotation et la bobine l'un de l'autre, et le moyen de séparation soit espacé du bouton de commutation de rotation par une opération de début de rotation qui commence une rotation du bouton de commutation de rotation et permet au bouton de commutation de rotation de reprendre son état d'accouplement à la bobine.
