Abstract: An adapter for coupling a lever to continuously unidirectionally drive a strap fastener is disclosed. The adapter includes a U-shaped frame with two free ends and a junction. The two free ends are separately provided with two shaft holes. Two sliding slots are separately formed near the shaft holes. A lever hole is formed at the junction. A ratchet shaft has an outer section with a radial hole and an inner section inserted in the shaft holes. A bolt is inserted into the radial hole. A ratchet is mounted around the ratchet shaft. A pawl is slidably disposed between the two sliding slots for engaging with the ratchet. A spring stopper is fixed between two sides of the frame. A spring is compressively arranged between the pawl and spring stopper. A holed plate is fixed between the spring stopper and the junction.

Abstract: A tie-down device includes a frame, a strap, a reeling unit, a driving unit and a gear box. The frame includes two walls extending from a base. The reeling unit includes a reel rotationally supported on the walls for reeling the strap. The driving unit is supported on the first wall. The gearbox connects the driving unit to the reeling unit.

Abstract: Apparatus and method for stringing aerial cables through tower structures using aircraft without requirement that a person be present on the tower while the aircraft is performing the stringing operation are described. An elongated needle-like threading member to which a sock line is attached and having spaced-apart projections emanating therefrom at different directions around the threading member, is directed by the aircraft pilot through a block having a pulley suspended by an insulator or other tower structure, the projections in cooperation with the block preventing the threading member from being pulled rearwardly under tension from the sock line. A device adapted for grabbing and releasing the threading member and attached to an aircraft haul line, permits the threading member to be hauled forward through the block once the aircraft flies to the other side of the tower and reattaches the grabbing device to the threading member.

Abstract: A tensioning apparatus includes a first shaft and a strap wound on the first shaft such that the strap has first and second portions extending in opposite directions, and the first portion of the strap is collected on the first shaft by operably moving the rotating shaft. The tensioning apparatus further includes a reeling device for collecting the second portion of the strap. Furthermore, the reeling device includes a ratcheting mechanism that facilitates collection of the strap.

Abstract: A securing mechanism for securing cargo that may include a body, a ratchet, a lever and a release mechanism. The body may be capable of receiving a strap therethrough, wherein the strap may includes opposing ends. The ratchet may include a pair of opposing arms connected to the body and a spool rotatably connected to the arms. The spool may include a slot to receive the strap into a z-fold configuration. The lever may be rotatably attached to the arms and reciprocated between an open position and a closed position, wherein the lever may include at least one pawl to engage the ratchet wheels and may rotate the spool when the lever is reciprocated. The release mechanism may be capable of selectively disengaging the pawl from the ratchet wheel. The securing mechanism may be selectively positionable along the strap when the strap is bi-directionally gathered onto the spool.

Abstract: The ratchet buckle for tightening a strap under a ratchet action provides a lock to positively prevent the ratchet buckle from inadvertently releasing the strap. The lock requires a removable handle to be installed on the ratchet buckle before the lock can be released. The removable handle extends the ratchet buckle crank arm for increased leverage in exercising the ratchet buckle and when removed reduces the overall size of the ratchet buckle and eliminates a crank arm portion that would otherwise extend beyond the ratchet buckle base.

Abstract: A ratchet tie-down includes a frame, a lever including two cams pivotally connected to the frame, a reeling device rotatably mounted on the frame and lever, and a ratcheting device including two ratchet wheels mounted on the reeling device. The ratchet tie-down further includes a reinforcement assembly including two reinforcement members mounted on the reeling device. Each ratchet wheel includes two lateral sides disposed between one cam and one reinforcement member. Each reinforcement member defines an annular surface in contact with one lateral side of one ratchet wheel, and with the reinforcement member imposing an urging force in a direction perpendicular to a rotation direction of the ratchet wheel.

Abstract: A tightener for a binding strap is disclosed. A base is penetrated with a rotating axle with a ratchet installed on its one end. A tooth limits the ratchet to move in a single direction. A driving element is mounted on the rotating axle. A ratchet tooth engages with the ratchet for the driving element to drive the ratchet. The driving element has a cam part and a blocking part.

Abstract: A cable tightening device includes a fixed unit including a base, a rotation member rotatably mounted on a first end of the base, a movable unit including a movable member rotatably mounted on the rotation member and movable relative to the base, and a holding member secured on a second end of the base. Thus, the base of the fixed unit is integrally combined with the holding member without having to provide a bolt and a nut, thereby decreasing the costs of fabrication. In addition, the holding member is integrally combined with the base of the fixed unit by punching so that the holding member will not detach from the base of the fixed unit, thereby facilitating operation of the cable tightening device.

Abstract: A cable tightening device includes a fixed unit, a rotation member rotatably mounted on the fixed unit, a movable unit including a movable member to drive the rotation member and a release member to lock or unlock the movable member, and a locking unit to lock the release member onto the movable member releasably. Thus, the release member is locked onto the movable member by the locking unit and cannot be pulled upwardly to detach the push plates of the movable unit from the ratchet wheels of the fixed unit so that the ratchet wheels are locked to lock the rotation member to prevent the cable from being loosened so as to protect the cargo wound by the cable, thereby achieving the anti-theft purpose.

Abstract: A tensioning device for a fastening strap comprises a base and a lever; a spindle pivotally connecting the lever to the base and adapted to permit the strap to be wound therearound, the spindle having a first spindle component and a second spindle component which together define therebetween a gap adapted for passage of a portion of the strap; and at least one ratchet wheel disposed around the spindle for rotating in concert with the spindle and driven by the lever to rotate the spindle, wherein the gap has a variable width that can be narrowed to cause the first and second spindle components to clamp the strap.

Abstract: A cable tightening device includes a fixed unit, a rotation member rotatably mounted on the fixed unit, a movable unit mounted on the rotation member and movable relative to the fixed unit to drive the rotation member to rotate relative to the fixed unit in a oneway direction, and a locking unit mounted between the fixed unit and the movable unit to releasably lock the movable unit onto the fixed unit. Thus, the movable unit is locked onto the fixed unit by the locking unit to lock the cable tightening device and the cable so as to protect the cargo wound by the cable, thereby achieving an anti-theft purpose.

Abstract: A strapping apparatus includes a frame. A first strap is connected to the frame. An axle is installed on the frame. A second strap is connected to the axle. A spool is positioned around the axle. The spool defines a slit through which the second strap is directed. Two ratchets are connected to the spool and rotationally installed on the axle. A coil spring includes a first end connected to the axle and a second end connected to the frame in order to rotate the spool. A first detent is movable on the frame between an operative position in engagement with the ratchets and an idle position away from the ratchets. A handle is pivotally installed on the axle. A second detent is movable on the handle between an operative position in engagement with the ratchets in order to rotate the spool and an idle position away from the ratchets.
