Patent attributes
First and second buckle members can be secured in a buckled configuration and can be separated in an unbuckled configuration by moving the buckle member(s) along an extraction direction. In the buckled configuration a row of one or more teeth of the first buckle member and a row of one or more teeth of the second buckle member can cooperate in responding to a tension force pulling the first buckle member away from the second buckle member along the extraction direction by opposing movement of the first buckle member away from the second buckle member along the extraction direction, and using the tension force to guide the first buckle member and the second buckle member laterally toward a centered position. A buckle can include this centering feature, a spring ejection mechanism, an obstruction to inhibit engagement with less than a predetermined number of teeth rows, and/or other features.
