Abstract: This invention primarily discusses the recent improvements to U.S. Pat. No. 6,473,944. The focus is on quick tightening/loosening of the lock that is formed between the ligature and the frame, managing the extra ligature length, decorating the system, improving performance and, extending the design to a wearable having structures similar to pants. In some applications a short ligature that passes underneath ligature loops and in others a donut-shaped object is used to solve tightening/loosening problems. Tucking the extra ligature length under an elastic strap or inside a slot formed within the frame manages the ligature. To enhance the performance of the system methods that reduce the friction between the ligature and the frame are discussed. Specifically, the use of back-to-back eyelet system, curved pathways between holes and, frictionless rollers are detailed. The invention discusses the used of a raised crisscross(s) as an additional method to enhance the performance.

Abstract: This invention discusses methods for forming an adjustable look between a ligature and a frame. Three methods of 2-Hole, 3-Hole and, Loop Turning along with their applications are discussed. Means for easy unlocking of the system are provided. Some of the many applications of the methods include usage in packaging and moving, in belt buckles, in bolts (including the scat belts), in tents pegs, in tents, in cargo covers, in convertible tops, in wearable items; including shoes clothing items, hair bows, helmets, gloves, etc., in luggage racks (including car top luggage racks).

Abstract: There is disclosed a pedal powered structure in which a frame carrying a seat and an axle with a pivotally mounted pedal on each side thereof is modified to include a pedal axle extension beyond the pedal at its inner and outer ends to provide inner and outer extensions, said pedal axle rotating on a bearing mounted within a crank assembly. Ligatures, one for each pedal axle extension, are connected at one end to one of the pedal axle extensions, at the other end to an element mounted behind and below the seat. The parallel ligatures spaced apart by approximately the width of the pedal, and straps are secured between each pair of parallel ligatures intermediate its length to rest upon the thigh of the rider above the knee when the rider is using the pedal powered structure.

Abstract: A bicycle is provided with an automatically variable gear ratio drive by employing a frame having a bifurcated truss rotatably supporting an axle for the rear wheel, this axle being fixed to the rear wheel for rotation therewith. A pedal assembly is positioned intermediate the wheels with a one-way clutch on the pedal assembly and a pulley is mounted on the rear wheel axle, this pulley being constituted by two laterally separated segments which are laterally moveable on the axle. A belt or chain interconnects the pedal assembly with the pulley, and an idler maintains tension on the belt or chain. The inner sides of the pulley segments are sloped and the outer side portions of the belt or chain are shaped to mate with these sloping sides so that tension on the belt or chain will cause it to move inwardly on the pulley to increase the gear ratio.
