ABSTRACT:
The safety hook disclosed herein includes a hook body that is comprised of a general cylindrical shank and a curved bill that defines a hook throat and terminates in a bill tip. An L-shaped latch member is arranged to close the hook opening and to be latched into closed position due to its engagement with the hook body and with the bill tip. Opening of the hook to receive the load requires linear and rotational movement of the latch member. Such movement is easily accomplished intentionally, but virtually impossible to accomplish inadvertently. Further, the latching mechanism may include apparatus for retaining the latch member in an open position when desired and also may include spring return means for returning the latch member to the closed position automatically.
