Abstract
A retractable strap load tie-down device includes a housing containing a tubular spool with a flat helical spring in its interior and a flexible tie-down strap wrapped on its exterior. The housing also includes a frame journaling a tensioning shaft for rotation where the tensioning shaft includes a slot through which the strap passes. Keyed to the end portions of the shaft are ratchet wheels and associate with the ratchet wheels are pawls that engage and disengage from the teeth of the ratchet wheels by action of a handle mounted, squeezable release bar that selectively displaces slide rods leading to the pawls. The handle will selectively rotate the tensioning shaft depending on the engagement of the pawls with the ratchet wheels. Swinging of the handle through an arc will tension the strap when the free end of the strap is anchored.
