Abstract

The Lace Ratchet Device (LRD) facilitates lace fastening and release. The LRD has two states: “active” and “inactive”. In the active position the device works as a lace ratchet allowing the lace to be pulled forwards but restricting any lace motion backwards. After fastening the lace remains fastened until the LRD is switched into inactive state by manually pressing a lever. Each LRD has a turning gate rotatably installed diagonally in a channel with front end which is covered with sheet metal with sharp edge. A preloaded spring keeps the LRD in active position when the lever is not pressed. The LRD doesn't employ serrated surfaces, which cause accelerated lace wear. Instead, the LRD's smooth front edge side and channel surfaces minimize lace wear. Parallel configurations of LRD pairs are suitable for fastening footwear and can be coupled with a clasp which clasps the laces' front ends to prevent dangling.
