Diver operated retractable pad eye |
摘要 |
A retractable pad-eye device for use in association with a plate-like wall having an opening includes a closure member for the opening and a pad-eye member, each connected by a jack-screw to a pivot-block that is rotatable mounted relative to the wall. By operation of the jack-screws with a wrench and rotation of the pivot-block, the closure member and the pad-eye member can be alternatively shifted between retracted or storage positions and operative positions in the opening.
