Abstract
A lift ring device arranged to normally remain in a flush condition, and involving a generally U-shaped lift loop pivotally mounted upon a base plate, such as a base plate mounted on the hatch lid of a boat. The lift loop is equipped with a pair of arm portions of substantially equal length, with each arm portion terminating in a pintle bent out of the plane of the lift loop. The base plate has a central recess defined over a substantial portion of its circumference by angled sidewalls, and in such recess the lift loop normally resides. A pair of symmetrically placed pintle-receiving holes are located in the sidewalls, which holes are elongate in a direction essentially perpendicular to the plane of the central recess. The interaction of the pintles of the lift loop with their respective holes is such as to prohibit the lift loop from residing in a perpendicular direction with respect to the base plate, thus assuring that the lift ring device will not represent a trip hazard.
