First Claim
Patent Images
1. An end-fitting buckle, comprising:
- a frame having a bottom;
a cover pivotally attached to the frame at a location on the frame spaced from the bottom so as to form a gap therebetween, the cover having a tail spaced from the pivotal attachment to the frame, the cover being rotatable between an opened position and a closed position, the tail being spaced from the bottom more in the opened position than the closed position;
teeth mounted on a side of the cover, the teeth mounted so that they face the bottom when the cover is in the closed position; and
a sliding bar connected for sliding movement relative to the frame, the sliding bar being mounted between the bottom and the cover when the cover is in the closed position;
wherein the teeth and the sliding bar are arranged so that a webbing is capable of being routed into the gap, around the sliding bar, and back through the gap, with the teeth engaging a portion of the webbing when the cover is in the closed position.

Abstract
An end-fitting buckle having a cam cover that allows webbing to be inserted when the cam cover is in an up position. After inserted, a free end of the webbing is pulled to tighten the webbing while the cover is in an intermediate position. The cover may then be closed to lock both the free end and load end. When the cover is locked, movement of the load end is prevented by teeth in the cam cover. The teeth lock the free end into place, holding the set position of the webbing. The cover design also promotes use of varied thicknesses of webbing, because the cam action of the cover utilizes friction between the two ends of the webbing instead of a pinching action.
