A ratchet buckle assembly which tightens a strap for binding a load. The assembly has its body 1 and handle 2 improved in mechanical strength, and prevents the load from being released from the strap by accident when the assembly is in its locked condition. A ratchet drive lever 4 is easily handled,
A ratchet buckle assembly which tightens a strap for binding a load. The assembly has its body 1 and handle 2 improved in mechanical strength, and prevents the load from being released from the strap by accident when the assembly is in its locked condition. A ratchet drive lever 4 is easily handled, and stabilized in its slidable operation. The assembly comprises: the body 1 constructed of arms 1a, 1b and a plate interposed therebetween; a winding shaft 7 constructed of plates 7a, 7b and supported between the arms 1a, 1b; a handle 2 constructed of arms 2a, 2b, a plate interposed therebetween and grips 10, 11; ratchet wheels 5a, 5b mounted on the shaft 7, wheel 5a being interposed between the arms 1a and 2a, the other wheel 5b being interposed between the arms 1b and 2b; a ratchet 3 for preventing the wheels 5a, 5b from rotating; and the lever 4 for rotatably driving the wheels 5a, 5b so that the strap is wound on the shaft 7.

A ratchet buckle assembly for tightening a strap, comprising: a main body (1) constructed of a pair of parallel-extending body arms (1a, 1b) and a plate interposed therebetween; a winding shaft (7) constructed of a pair of plates (7a, 7b), said winding shaft (7) being supported between said body arm
A ratchet buckle assembly for tightening a strap, comprising: a main body (1) constructed of a pair of parallel-extending body arms (1a, 1b) and a plate interposed therebetween; a winding shaft (7) constructed of a pair of plates (7a, 7b), said winding shaft (7) being supported between said body arms (1a, 1b); a handle (2) constructed of a pair of parallel-extending handle arms (2a, 2b), and having a plate interposed therebetween and a pair or plastic grips (10, 11), each of said handle arms (2a, 2b) being provided with a pair of projections (2c, 2d); a pair of ratchet wheels (5a, 5b) one wheel (5a) of which is interposed between said body arm (1a) and said handle arm (2a) and mounted on said winding shaft (7), the other wheel (5b) of which is interposed between said body arm (1b) and said handle arm (2b) and mounted on said winding shaft (7); a ratchet (3) for preventing said ratchet wheels (5a, 5b) from rotating said ratchet having a locking hole (3c) formed in each of opposite ends (3a, 3b) of the ratchet (3); and a ratchet drive lever (4) for rotatably driving said ratchet wheels (5a, 5b) so that a strap can be wound on said winding shaft (7); wherein said main body (1), said handle (2) and said winding shaft (7) are rotatable independently of each other; said ratchet wheels (5a, 5b) are fixedly mounted on said winding shaft (7) so as to be rotatable together with said winding shaft (7); said ratchet (3) is slidably mounted in a pair of slots formed in said body arms (1a, 1b); said ratchet drive lever (4) is slidably mounted in a pair of slots formed in said handle arms (2a, 2b); said ratchet drive lever (4) is engaged with said ratchet wheels (5a, 5b) to rotatably drive said winding shaft (7) as said winding shaft (7) rotates; and said ratchet (3) is engaged with said ratchet wheels (5a, 5b) to prevent said winding shaft (7) from being reversely rotated.
