  • Patent number: 8209821
    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.

  • Patent number: 8157245
    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.

  • Patent number: 7618021
    Abstract: A winch used for tightening a strap to retain an article, which may be cargo, on the deck of a vehicle has a ratcheting mechanism which tightens the strap around a cylindrical shaft. A ratchet cap installed on the winch has two sections. One of these sections is fixedly attached to the winch drive shaft This first section has a plurality of spaced recesses running around a surface plate thereof. Spring urged pins with rounded end surfaces are mounted in receptacles formed in the second cap section. The rounded ends of the spring urged pins are urged against the surfaces of the recesses. The pins are prevented from moving out of the recesses in one direction by a right angled end portion of the recess in this one direction and are free to move out of a recess over a slanted recess end portion into an adjoining recess in the opposite direction. At least one aperture is formed in the cap into which a lever for driving the winch is fitted.

  • Patent number: 7584940
    Abstract: A tree stand lock apparatus comprises a ratchet buckle part and a wire rope part. The ratchet buckle part comprises a spool with a transaxial bore, a ratcheting lever handle, a locking means and a base affixed to a hook. The wire rope part comprises a wire rope, one end of which is affixed to a hook. The lock may be employed by wrapping the wire rope around a portion of a tree stand, hooking the hook of the rope to the hook of the ratchet buckle and threading the wire rope through the transaxial bore. The ratchet buckle is operated to render the wire rope taut and the buckle is locked in the closed position.

  • Patent number: 6682053
    Abstract: A protective pad made of soft materials is joined to a metallic finger-operated element of a winch for a lashing rope. The finger-operated element has a flat main body, and two spaced-apart plate portions, which stick outwards substantially perpendicular to the main body to be pushed for allowing the winch to be moved to a locked position. A portion of the protective pad covers the plate portions. Thus, a user doesn't have to contact the metallic finger-operated element directly in using the winch, eliminating the risk of the fingers getting hurt by sharp edges of the metallic element. Being made of soft materials, the protective pad is to provide the user with more comfortable touch than the relatively hard plate portions of the metallic element in operating the winch.

  • Patent number: 6162677
    Abstract: In a semiconductor device fabricating method for fabricating a semiconductor device having a high-density region in which transistors are arranged with a relatively high density, and a low-density region in which transistors are arranged in with a relatively low density, a silicon nitride film of a thickness great enough for the silicon nitride film to serve as a stopper is deposited over the entire surface of the silicon wafer, so that regions between the transfer gates in the high-density region may not be blocked up after removing side walls formed in the entire transistor region. A part of the silicon nitride film in the low-density region, namely, a peripheral circuit region, is removed.
