Abstract: A buckle assembly includes a main frame which is generally U-shaped and has a pair of parallel opposing side plates and a bottom formed by a plurality of cross-bars. Pivotally mounted on the main frame is a strap-tightening handle which is utilized to tighten a strap and to retain it in the tightened position. This handle includes a tightening cross-bar around which the strap is looped, and the two opposite ends of such strap then run under one of the cross-bars of the main frame. A limit stop member is provided in at least one of the side arms of the frame to limit the downward travel of the handle in its strap-tightening position. This assembly is further adapted to be locked in position in conjunction with a security locking device such as a padlock.

Abstract: An anchor fitting has flat surface pads with shoulders extending therefrom and a post portion extending along an axis substantially normal to the flat surfaces of the pads. A latching plunger is slidably mounted on the post portion for motion along the longitudinal axis thereof. The fitting is removably retained in a selected position along a slotted track having a plurality of notched portions separated by narrow neck portions formed by flanges with the shoulders of the pads in the track slots underneath the flanges and the latching plunger member seated in one of the notched portions of the track. A cam bar member is supported on the anchor fitting in an apertured portion thereof by means of an adjustment screw. This bar member is drawn against the walls of the apertured portion of the anchor fitting such that it drives against the surface of the track drawing the shoulders of the pads tightly against the walls of the track to provide a tight rattle-proof joinder between the fitting and the track.
