Abstract: An innovative and advantageous ratcheting system having a housing, a corresponding ratcheting member, and a primary ratcheting member. Wherein the members provide dependent interlocking behavior between the corresponding ratcheting member and the primary ratcheting member whereby the dependent interlocking behavior takes place on the adjoining surfaces orthogonal to the axis in which the ratcheting mechanism is rotatably mounted. Such interlocking behavior is dependent upon the direction of relative torque between the corresponding ratcheting member and the primary ratcheting member thereby allowing relative rotary motion in the first predetermined direction while preventing relative rotary motion in the second predetermined rotary direction. Further, the interlocking behavior between the corresponding ratcheting member and primary ratcheting member can be disabled whereby relative rotary motion between the ratcheting members can be achieved in the second predetermined rotary direction.

Abstract: A cable winding device comprises a case, a reel disc, a cable, and a cable locking structure. The case comprises a first case element and a second case element. The reel disc is disposed between the first case element and the second case element, wherein the reel disc has a leaf spring. The cable is wound on the reel disc.

Abstract: A retractable tow strap apparatus includes a housing containing a spool operably connected to a crank on the exterior of the housing. A tow strap is wound around the spool, the ends of the strap extending through a pair of apertures on opposite sides of the housing. Unwinding the strap from the spool through the apertures rotates the spool in a first direction. The strap is retrieved onto the spool by rotating the spool in a second direction using the crank. Springs within the housing apply a braking force on the portion of the strap that is on the spool, whereby slack in the strap and resultant tangling may be minimized as the strap is wound and unwound from the spool. The strap is formed of a unitary webbing element that extends through the spool, thereby minimizing the application of tension forces directly to the spool during a towing operation.

Abstract: A retractable cable device having protecting function mainly comprises a housing, a spiral spring, a spool disk, an arresting system, and a communication cable. The spool disk pivoted on a shaft within the housing is wound by the communication cable. The spiral spring provides the spool disk with a reeling force to reel in the communication cable. The rotation of the spool disk flexibly controlled by the arresting system decides the protruding length of the communication cable. A swaying member installed on the spool disk is utilized to replace the conventional immovable clip for fixing the communication cable. Whereby, when the entire communication cable is drawn out, the communication cable at a second end of the swaying member presents a larger bent angle. Therefore, the communication cable is subjected to bending with less sharp degree, thence protecting the communication cable, especially for the core, by preventing it from damage.
