Abstract: There is described a winch lock assembly which serves to cinch a sack and its contents closed, thereby locking said contents inside said sack, and at the same time, containing the cinch cord within the winch lock assembly. The winch lock includes a crank assembly, to hand-wind the cinch cord on a shaft inside said winch lock body. When said cinch cord is adequately wound up in order to close the cinch sack, additional force may be applied to said cord with the thumb and index finger of the hand, without said cord unwinding between said torque strokes, due to the clutch-breaking effect of the wound-up cord inside said winch lock body. The crank handle is pivotally mounted on a crank assembly, so as to be folded into crank assembly, thereby locking the crank assembly to said winch lock body.This is accomplished by a locking surface on the crank handle that moves into slots cut into the winch lock body when said handle is folded into the crank assembly.

Abstract: A tensioning member for achieving and maintaining a desired tension in a flexible strap, web or belt is provided. The tensioning member includes an elongate tensioning member having a pair of cam-like cross-members around which the strap is threaded. The elongate member is rotatable through substantially 180.degree. of arc from a release position to a tensioned position. In the tensioned position, the path of the strap through the tensioning member is longer than when the tensioning member is in the release position. This causes the tension in the strap to increase as the tensioning member is rotated from a release position to the tensioned position. One end of the tensioning member is extended to provide a mechanical advantage for rotating the member to the tensioned position. A keeper or retainer encircling the strap and movable therealong engages the extended end of the tensioning member to secure the tensioning member in the tensioned position.

The tab allows the strap to move in a first direction and prevents movement of the strap in a second direction. A lever arm is pivotally mounted about the housing about the first axis and a second axis which is spaced from the first axis. When the lever arm is pivoted about the second axis, saw teeth engage the rack of teeth on the strap to incrementally ratchet the strap through the housing in the first direction.

Abstract: An apparatus for tightening elastic and non-elastic bands designed for fitting to the frames of pieces of furniture includes a tensioner consisting of a roll arranged for rotation about its own axis. The roll has a pressure member mounted in spaced relationship with the roll so as to permit insertion of bands therebetween. The supplied band is folded backwardly over the top of the pressure member to be fastened to the frame of the piece of furniture. During a first rotation of the roll, the pressure member applies, by friction, a slight tractive force on the band, while permitting it to run with respect to the roll. A subsequent rotation of the roll brings the backwardly folded portion of the band to bear on that portion of the band supplied from the reel, which lies on the least one portion of the surface of the roll, whereby running of the band is then prevented by friction such that a further rotation of the roll causes tightening of the band.

Abstract: A tensioning apparatus for the step-wise tensioning and non-stepped releasing of a lashing strap includes a frame (1; 100), a pivot lever (2) having two pivot arms (16, 16'), and a ratchet mechanism that includes ratchet wheels (3, 3') and locking pawls (5, 5'; 105, 105'). By using a plurality of locking pawls (5, 5'; 105, 105'), the tensioning apparatus is able to absorb a greater lashing force or to tension the lashing strap in locking steps which differ from the tooth pitch t. To release the lashing strap, cams (40) on the pivot arms (16, 16') of the pivot lever (2) move the locking pawls and thus the ratchet mechanism to a disengaged position. The structural height of the tensioning apparatus and the number of components required for it may be reduced by using curved locking pawls (5, 5'; 105, 105'), a curved driving pawl (20), and a leg spring (41) which serves as the sole spring element for biasing the locking pawls.

Abstract: A tensioning assembly for the stepwise tightening and releasing of a tensioning strap includes a frame (1), a tensioning lever (2), and a wind-up spindle (4) supporting ratchet wheels (3, 3'). A driving pawl (19) which is movably mounted on the tensioning lever (2) serves to rotate the wind-up spindle (4) when the strap is being tightened. Reverse rotation of the wind-up spindle (4) is prevented by a pair of locking pawls (5, 5') which are movably mounted on the frame (1). The lower or bearing end of the tensioning lever (2) has an unlatching cam (37) which permits the locking pawls (5, 5') to be alternatingly moved out of engagement with the teeth of the ratchet wheels (3, 3'), thus promoting safety by relieving the strap tension in stages. An isolating cam (40) at the bearing end of the tensioning lever (2) permits both locking pawls (5, 5') to be disengaged after the strap tension has been reduced.
