Abstract
A ratchet buckle for tightening and tensioning straps includes a bifurcated frame member having a pair of oppositely positioned parallel arms, between which a reel member and ratchet wheels are rotatably mounted. A strap to be tensioned is reeved through the reel member. A bifurcated lever member having a pair of oppositely positioned parallel arms is rotatably mounted on the reel and has a ratchet drive plate which engages the teeth of the ratchet wheels such that when the lever is actuated, the reel is rotatably driven. A latching plate is mounted on the frame which engages the ratchet wheels to latch these wheels at times when they are not being rotated by virtue of driving action of the lever. This latching plate is secured in position and prevented from unseating from engagement with the teeth of the ratchet wheels by virtue of the engagement of an undercut portion of the latching plate with retaining and camming elements formed on the lever. Further, notches are formed in the arms of the frame into which a cross member, which runs between the arms of the lever, fits and is seated, such that a portion of the load on the frame is transferred into the lever when the buckle is in the closed position.
