ABSTRACT:
A releasable fastener for securing together two straps, includes a link adapted for attachment to one such strap and shaped as a generally plate-like strike having a pair of spaced-apart locking lugs on opposite edges defining locking notches. A guide channel is provided in one surface of the strike intermediate the lugs for guiding the link into engagement with a buckle adapted to be secured to the other such strap. The buckle is formed by a body having spaced-apart upper and lower plates defining a slot for receiving the strike. A pair of spaced-apart lock-pins extend through the upper plate and said slot into the lower plate, with the portion of said lock-pins exposed between the said plates being notched to define lands for engaging into the locking notches on the strike. The lock-pins are rotated to position the lands in the notches by a slide mounted on the upper plate. The slide includes a flanged slide post slidably positioned in an elongated slot defined in the upper plate with the flange engaging the under-surface of the upper plate to hold the slide thereon. A spring on the post biases the slide to its forwardmost position. Bifurcated levers secured to the upper ends of the lock-pins, with the forked ends thereof engaging said post, serve to rotate the lock-pins in response to sliding movements of the slide. A latch is pivotally mounted on the buckle body for rotating movement in response to a force thereon acting in a direction opposite to the force required to move the slide to the strike unlocking position. Until the latch is thus rotated, interfering surfaces on the slide and latch prevent inadvertent movement of the slide.
