ABSTRACT:
A releasable fastening device for use in joining straps, laces, filaments and the like is disclosed. The fastening device may be used to join the laces or closure components of a shoe, for example, or in any of various devices in which filaments, straps and the like are advantageously bound in a quick release mechanism. The invention includes a pair of thin planar, elongated strips, each of which has a plurality of ribs positioned transversely along the length thereof. Each of the ribs has a planar side face positioned at an angle of about 45 to 75 degrees relative to the plane of the upper surface of the planar strip to which it is attached. The planar strips may be provided as part of the respective straps, laces or the like to be fastened. Alternatively, the ribs may be affixed to a separate strip and the strip then secured to a planar surface of the strap or lace. For optimal ease of engagement of the ribs of one strip with those of a second strip, the rear top surfaces of the ribs should be rounded or slightly relieved.
