Abstract

A device for fastening laces. The device includes a multiplicity of channels. Each channel has an upper part rotatably mounted on lower part and a resilient gate which is installed diagonally. The front ends of the gates are sharp and free to move. They can squeeze laces which pass through the gates'"'"' gaps with their opposite channel walls. The gap widths are controlled by a locking mechanism, which the user can activate by rotating the upper part relative to the lower part. When the gaps are narrowed, the gates squeeze the laces and act as lace ratchets i.e. allowing the laces to move only forwards. The ratchet operation enables the user to fasten the laces and they remain fastened as long as the locking mechanism is in locked position. When the locking mechanism is switched into opened position the gaps are widened and the laces are released.
