Abstract: A safety hook includes a hook body, a pivotable safety retainer biased to a locking position, and a pivotable latch member biased to abut against a distal end of a hook portion of the hook body to thereby close a hook mouth defined by the hook body. The safety retainer includes a stop portion and an abutment face unit. When the safety retainer is disposed in the locking position, the stop portion abuts against the latch member, and the abutment face unit is adjacent to and spaced apart from a stop block of the hook body. In the locking position, if an external force is applied to pivot the latch member away from the distal end of the hook portion, the abutment face unit will come into contact with the stop block to prevent further pivoting movement of the latch member.

Abstract: A safety hook for mounting on the extremity of a spreader bar of a patient lift is secured to a base member that is connected to or integral with the spreader bar. A load-bearing hook member is pivotally suspended from the base member to allow the hook member to move in the plane of the hook member between an open position and a closed position in which the free end of the hook member engages the base member at an engagement point. The hook member is shaped such that it is urged to the closed position when a downward load is applied to it, and that it is urged to the open position when an upward load is applied to it. Under normal circumstances the safety hook closes automatically because of the weight of the load.
