发明名称 Reusable tying device
摘要 The invention disclosed relates to an improvement for tying devices which can be secured to laces particularly on shoes for holding the shoelace knot in place. The device disclosed employs a mechanism for securing a portion of the device to the shoe and enabling the device to be reused for securing a knot in place each and every time the laces are tied. In the embodiment disclosed, the invention also incorporates elastic or semi-rigid means for engaging the shoelace knot from opposed sides to impede the knot from becoming untied while simultaneously exposing the knot for view and maintaining the normal appearance of the bow.
