Abstract

The Lace Ratchet System (LRS) is a parallel configuration of two Lace Ratchet Devices (LRD) which facilitate two laces fastening. The LRD has two states: “active” and “inactive”. In the active state the device works as unidirectional 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 releasing a latch. Each LRD has a turning gate rotatably installed diagonally in a channel with a sharp metallic front end. A resilient plate serves as preloaded spring that keeps the LRD in active position when the spring is not released. The LRD's smooth front end side and smooth channels' floors minimize lace wear. The LRS can be coupled with a clamp which clamps the laces' front ends to prevent dangling. The entire LRS except the blades is made of plastic.
