Abstract
A ratchet-type buckle () is disclosed for use with a ladder strap (), wherein the buckle includes a toothed, barrel-shaped strap engagement member () that is rotatably mounted between oppositely disposed sidewalls () that are pivotally coupled to a base (). The engagement member is positioned to drivably engage and hold the strap. A holding pawl () allows forward rotation and hinders backward rotation of the engagement member. A driving pawl () is incorporated into a lever assembly (), which is pivotally coupled to the sidewalls, the driving pawl positioned to engage and rotate the engagement member teeth when the lever assembly is pivoted in a forward direction. The pivotal coupling of the sidewalls to the base permit the engagement member to be lifted away from the base, to release the strap. The sidewalls are preferably biased towards the base.
