<p>PROBLEM TO BE SOLVED: To provide a string fastener by which, in fastening a string, the string is made hard to be untied by holding a string-like object and fastening it instead of tying the string and by which fastening and releasing of the string can be done by a simple operation.SOLUTION: A hole for putting a string through is drilled in two left and right places in a body, with a handle installed in the center of the body. The handle is mounted with a cam, and a holding plate for holding the string is installed on both sides of the cam. The holding plate holds the string which is put through between the holding plate and a holding part inside the body. The string put through the hole goes through the holding plate and the holding part inside the body. By turning the handle, the cam fastened on the handle is interlocked. The rotation of the cam makes the holding plate move with the stroke of the cam, thereby holding the string together with the holding part inside the body and fastening it.</p> |
