发明名称 Training shoelace
摘要 A shoelace is described for use by young children or the handicapped, which facilitates tying of a bow. The shoelace has opposite end portions which are just stiff enough to substantially retain the shape to which they are bent while permitting children to easily bend them during the tying of a bow. This enables a child or handicapped person to bend the end portion to the shape required for one step of tying, and to "freeze" the shoelace in that position while he manipulates the other end portion or decides what is the next step to be done.
