One-way clutching methods between a ligature and a frame and their applications

A device for creating a one-way clutching action between a ligature and a frame;

• said frame comprising of one or more sets of three holes;
• said three holes in each said sets being named hole1, hole 2 and hole 3;
• inner edge to inner edge distance between said holes 1 and 2 being approximately equal to the diameter or the width of said ligature;
• said holes 1 and 2 having diameters approximately equal to the diameter or the width of said ligature;
• in a preferred practice said holes 1, 2 and 3 form a triangle;
• one end of said ligature enters and exits said holes 1 and 2 sequentially forming a ligature loop called loop 1;
• said ligature end then enters and exits said hole 3 before passing underneath said loop 1;
• a relative motion between said frame and said ligature being possible in one direction when tensile force is applied to said ligature ends;
• to create a gap between said frame and said ligature, said frame comprises of an opening separating said holes 1 and 2 from said hole 3;
• alternatively said hole 3 can be set at a higher elevation than said holes 1 and 2 to create a gap;
• said gap providing a space for user's fingers to hold said ligature to release and to adjust;
• said frame comprising of symmetric curvature on its boundaries;—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.

A securing means for pulling opposite sides of a wearable toward each other;

• said securing means comprising of a ligature and a frame;
• said wearable having a longitudinal opening with rows of holes alongside said longitudinal opening;
• said frame having 5 holes;
• a centrally positioned hole and holes 1, 2, 3, and 4;
• inner edge to inner edge distance between said hole 1 and hole 2 being approximately equal to the diameter or the width of said ligature;
• inner edge to inner edge distance between said holes 3 and 4 being approximately equal to the diameter or the width of said ligature;
• in a preferred practice, said holes 1 and 2 being mirror images of said holes 3 and 4 with respect to said centrally positioned hole;
• one end of said ligature after criss-crossing through all but the last hole of said wearable on its respective side enters and exits said holes 1 and 2 sequentially forming a loop named loop 1;
• said ligature end then enters and exits said last hole of said wearable on its respective side before entering and exiting said centrally positioned hole of said frame;
• said ligature end then passes underneath said loop 1;
• ligature segment immediately out from under said loop 1 being named pull segment;
• said ligature end then forms a complete loop around said loop 1 by passing underneath loop 1 for the second time;
• the other end of said ligature interacts with said holes 3 and 4 in similar fashion;
• said complete loops formed by said ligature ends are fastened together by fastening means;
• pulling said pull segments tightens said wearable by forcing the sides of said longitudinal opening closer together;
• said wearable can be loosened by pulling said fastening means upward.

A securing means for pulling opposite sides of a wearable toward each other;

• said securing means comprising of a ligature and a frame;
• said wearable having a longitudinal opening;
• said wearable comprising of rows of holes alongside its longitudinal opening;
• said frame having 5 holes;
• a centrally positioned hole and holes 1, 2, 3, and 4;
• inner edge to inner edge distance between said holes 1 and 2 being approximately equal to the diameter or the width of said ligature;
• inner edge to inner edge distance between said holes 3 and 4 being approximately equal to the diameter or the width of said ligature;
• said holes 1 and 2 being a mirror images of said hole 3 and 4 with respect to said centrally positioned hole;
• one end of said ligature enters and exits said holes 1 and 2 sequentially forming a loop named loop 1;
• each of said ligature ends then enter and exit a hole on one side of said longitudinal opening of said wearable;
• said ligature ends then enter and exit corresponding holes alongside the opposite side of said longitudinal opening of said wearable;
• one end of said ligature then enters and exits said hole 3;
• the other end of said ligature then enters and exits said hole 4;
• both said ligature ends then enter said centrally positioned hole before passing underneath said loop 1;
• said ligature ends then form a complete loop around said loop 1 by passing underneath said loop 1 again;
• fastening means secure said complete loop around said loop 1;
• tightening is done by pulling ligature segments from underneath said loop 1;
• loosening is done by sliding said frame sidewise.

A securing means for pulling opposite sides of a wearable toward each other;

• said securing means comprising of a wearable and ligature;
• said wearable having a longitudinal opening;
• said wearable comprising of a row of holes along both sides of said longitudinal opening;
• each of said rows of holes comprising of at least one set of 3 holes;
• said 3 holes of each set being named hole 1, hole 2 and hole 3;
• said 3 holes of each set, in a preferred practice, forming a triangle;
• inner edge to inner edge distance between said holes 1 and 2 of each set being equal to the diameter or the width of said ligature;
• one end of said ligature enters and exits holes 1 and 2 of a said set of 3 holes forming a loop named loop 1;
• said ligature end then enters and exits hole 3 of the same said set before passing underneath said loop 1;
• said ligature end then forms a complete loop around said loop 1 by passing underneath said loop 1 again;
• fastening means secure said complete loop around said loop 1;
• the other end of said ligature interacts the same way with the corresponding set of 3 holes on the opposite side of said longitudinal opening.

A ligature ladder comprising of two parallel ligatures;

• said parallel ligatures being intermediated by sets of bodies;
• one end of said parallel ligatures being fastened at an elevation;
• the other end of said parallel ligatures being fastened to the ground level or left hanging free;
• each of said bodies, in a preferred practice, comprising of 4 holes;
• two holes being positioned close to one end of said body and the two other holes being positioned close to the opposite end of said body;
• one of ligature ends enters and exits a hole close to one end of said body;
• said ligature end then forms a ½ turn loop around said body before entering and exiting from said second hole located at the same end of said body;
• the other ligature interacts with the other end of said body in the same fashion;
• other bodies interact with said parallel ligatures in the same fashion;
• said bodies having free relative motion along said parallel ligatures;
• locking of said bodies to said parallel ligatures is done by turning said ½ turn loop from one side to the other side over the corresponding end of said bodies;
• said loop turning locks said bodies to said ligatures in one direction.

An ascending/descending device comprised of a pair of ligatures and pair of rigid bodies;

• said ligatures serve as a pathway;
• said rigid bodies travel over the length of said ligatures;
• each of said rigid bodies having a sets centrally located paired holes;
• one end of said ligatures being fastened to an elevation;
• the other end of one of said ligature enters and exits one of said centrally located holes of one of said rigid bodies;
• said ligature end then forms a ½ turn loop around said rigid body before entering and exiting the second centrally located hole of said rigid body;
• the other said ligature and other said rigid body interact with each other in the similar fashion;
• when ascending the said ½ turn loops of said ligatures are turned from one side to the other;
• said loop turning causes a one-way locking between said ligatures and said rigid bodies enabling ascender to pull and push said rigid bodies along said ligatures;
• when descending, said ½ turn loops are turned back to their original position.
