Abstract:
A device for creating a one-way clutching action between a ligature and a frame; said frame comprising of one or more sets of paired holes; in each said sets one hole of said paired holes being named hole1 and the other hole 2; said holes 1 and 2 having diameters approximately equal to the diameter or the width of said ligature; inner edge to inner edge distance between said holes 1 and 2 being approximately equal to the diameter or the width of said ligature; one end of said ligature enters and exits said holes 1 and 2 sequentially forming a ligature loop named loop 1; said ligature end then forms a second loop around an edge of said frame before passing underneath said loop 1; a relative motion between said frame and said ligature being possible only in one direction when tension is applied to said ligature ends; said frame having stepped structure along its boundaries creating a gap between said ligature and said frame; said gap providing space for user's fingers to hold and pull said ligature from underneath said loop 1 for quick release or adjustment;â€”alternative way to facilitate loosening of the lock formed between said frame and said ligature is to form a complete loop around said loop 1 by passing said ligature end underneath said loop 1 a second time; fastening means secure said complete loop around said loop 1; pulling said complete loop upward unlocks the system.
