Publication number: 20010045548Abstract: A ratchet and cam buckle tensioning assembly or strap tensioner, interposed between a lashing strap tensioned by the ratchet buckle and a lead strap tensioned by the cam buckle. The invention enables an operator to quickly and conveniently pre-tension the lashing and lead straps by removing an un-tensioned length of the lead strap without having to operate the ratchet buckle. The tensioning assembly includes a ratchet buckle for tensioning the lashing strap in stepped increments and a cam buckle for slidingly adjusting the lead strap. The cam buckle housing and the ratchet buckle frame member are a unitary member, forming an single, integrated tensioning assembly. Alternately, the cam buckle is permanently attached adjacent to the ratchet buckle. The cam buckle includes a housing adapted to slidably receive the lead strap. The housing has a pressure plate with a first restraining surface, such as a friction surface, over which the lead strap slides.Type: ApplicationFiled: July 6, 2001Publication date: November 29, 2001Inventor: Richard Landy

Patent number: 6095450Abstract: A winding device includes a hand crank, a securing substrate plate, and two unidirectional gears pivotally coupled between the hand crank and the substrate plate by a pivot member. A pivot member is inserted, in one operation, through axial holes of pivot mounting portions of the hand crank and the securing substrate plate, and through a semicircular through holes of the unidirectional gears to pivotally couple the hand crank with the securing substrate plate and unidirectional gears. The pivot member includes two semi-circular pivot portions that are disposed parallel and opposite to each other. Each pivot portion is formed by curling and bending a plate into a semi-circular structure. The pivot portion includes a curved face and two curled portions disposed on an inner side of the curved face. The curled portions have end portions curling in opposite directions and abutting the inner side of the curved face at different points so as to increase the bending strength of the curved face.Type: GrantFiled: February 8, 1999Date of Patent: August 1, 2000Assignee: Pei Chi Enterprise Co., Ltd.Inventor: Sen-Jong Jang

Patent number: 5368281Abstract: A ratchet-type tensioning mechanism for a rope or cord has a rotatable sheave with faces having radially extending serrations. A releasable ratchet mechanism permits rotation of the sheave in one direction but not the other. A plurality of serrations circumscribes the sheave, which is closely fitted within a curved surface within a housing within which the sheave is rotatably mounted. The curved surface forces the rope into the sheave and maintains it in non-slippiong contact therewith. An opening in the side of the housing can be provided to permit hand rotation of the sheave. The device optionally may include a ratcheting lever arm which engages the wheel and affords leveraged tensioning the rope.Type: GrantFiled: January 4, 1993Date of Patent: November 29, 1994Inventor: Helmut K. Skyba

Patent number: 5271606Abstract: A tensioning apparatus for a lashing strap (8) includes a frame (1) having side walls (5, 5'). One end of the lashing strap (8) is fixed to the frame. A spindle (11) is rotatably secured to the frame (1), bridging the space between the side walls (5, 5') and bearing a tensioning lever (17) for winding the lashing strap (8) up from its free end. Ratchet devices that are employed at either end of the spindle (11) permit the operator to select whether a push or a pull on the tensioning lever (17) is to turn the spindle (11). Each ratchet device includes a ratchet wheel (14; 14') fixed to the spindle (11), a ratchet securing mechanism (70) disposed at the frame (1), and a tensioning ratchet mechanism (80) disposed at the tensioning lever (17).Type: GrantFiled: February 19, 1991Date of Patent: December 21, 1993Assignee: Spanset Inter AGInventor: Hans-Werner Kamper

Patent number: 5186586Abstract: A remote release mechanism is disclosed which permits restraints such as flat straps placed around a load and placed in tension by a winch to be released by an operator positioned on the same side of the transportation structure as the winch. Thus, the present invention permits the hook end of a load restraint to be released from the winch side of the transportation structure, thereby eliminating the need to perform separate operations on either side of the restraint mechanism. In a preferred embodiment, the present invention provides apparatus comprising a hook bar connected to a rotatable drum which is held from rotation in one direction by a ratchet and pawl. Upon release by the application of force to a remote release rod, the hook bar is released and permitted to rotate, thereby causing the hook which connects the restraint to the hook bar to fall away, releasing the restraint. Methods of remotely releasing a load restraint are also disclosed.Type: GrantFiled: June 11, 1992Date of Patent: February 16, 1993Assignee: Union Camp CorporationInventor: Everett H. Stephenson, Jr.

Patent number: 4584741Abstract: A clasping device which has a main assembly including a body, and a lever connected by means of links. A first hook is connected with the body, while a second hook is connected with the lever by means of a strap. The strap can be tightened and loosened by rotating the lever between the release and tightening positions. The body has a claw member for temporarily holding the tightened strap. Therefore, by utilizing the claw member, the lever can be repeatedly operated in order to increasingly tighten the strap.Type: GrantFiled: July 18, 1985Date of Patent: April 29, 1986Assignee: Ryusyo Industrial Co., Ltd.Inventors: Akira Kawahara, Akihiko Chiba

Patent number: 4542883Abstract: A tensioner for straps, especially for systems for keeping loads in position, has an anchoring means for the fixed end of the strap and a strap drum worked by a ratchet, the drum then acting as a winch for tensioning the strap. The drum has a locking pawl that may be moved clear of it. The tensioning ratchet has tooth means on the side of the strap drum so that a driving pawl fixed on the ratchet lever and loaded towards the strap drum by a spring, may be put into driving connection with the tooth means. The ratchet lever further has means limiting the torque that may be transmitted to the tooth means on operation of the ratchet lever by having the driving pawl spring-pre-loaded tangentially in relation to the strap drum.Type: GrantFiled: October 3, 1983Date of Patent: September 24, 1985Inventor: Edith Rutzki
