This invention relates for creating a one-way clutching action between a frame body member (1) and a ligature (6). Three methods defined by two (2) and three (3) hole arrangements and loop (9) turning method. In either of the methods, properly spaced, strategically located holes (2 and 4) of proper size are provided within the body of the frame (1). These methods have variety of usage and can be applied to many different applications. Examples by a single body knot (17) for positive locking, and infinite adjustment, and comes apart with ease. Or by other products where a one-way clutching provides definite advantages. The invention extends the methods to the ligature ladders and other ligature ascending devices also. The structure in either case comprises of parallel ligatures (109, 110) and stepping element (111) the steps (111) connected to the ligatures (109, 110) by one-way clutching. The steps (111) connected to the ligatures (109, 110) by a loop (116) turning method. |
