16 COLLAPSIBLE ANCHOR HAVING RELEASABLE FLUKES ABSTRACT OF THE DISCLOSURE A simple, easily affordable and portable, yet rugged and reliable, collapsible anchor is disclosed for use with small water craft, particularly those susceptible to damage by sharp edges or protuberances of a conventional non- collapsible anchor stowed aboard. When snagged, the anchor is self-tripped by a force exerted in a direction upstream from where the craft was anchored. The force trips a release mechanism which allows a pair of flukes to rotate in an "A"-shaped spring yoke in which they are held, and unsnag the anchor. The flukes are nonrotatably disposed on a fluke shaft which is journalled in the lower terminal portions of the yoke's two spring arms. The upper terminal portions (apex) of the yoke are held together by a fulcrum pivot (shoulder bolt) means. The release mechanism comprises, a spreader bar having a clevis in its upper terminal portion and a release pin in its lower terminal portion, the release pin being biased against the spring arms; and, a line lever having a through-bore in its lower terminal portion and a cam end, the anchor line being attached to the other end. The line lever is pivotable about the fulcrum pivot member, and held in the clevis so that the spreader bar is rotatably disposed on the same fulcrum pivot.
