  • Patent number: 4978304
    Abstract: A training aid for shoelace tying includes an expandable generally cylindrical sleeve having a center passage adapted to be received upon a variety of shoes and alternatively to be placed upon a human hand. A plurality of eyelets are supported upon the sleeve and arranged generally in an equally spaced array of two rows. A flexible shoelace is secured to the sleeve through the eyelets such that the end portions of the shoelace emerge from the sleeve interior and extend outwardly therefrom. In an alternate embodiment, the sleeve is formed largely of a nonelastic material and includes an elastic panel which provides expansion of the sleeve to accommodate different attachments.

  • Patent number: 4842522
    Abstract: 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.
