LOCKING MECHANISM WITH MULTIPLE STAGE LOCKING VERIFICATION
First Claim
1. A locking mechanism comprising:
- a receiver base having a plurality of locking mechanisms configured to securely engage an device, at least one of the plurality of locking mechanisms including an indicator configured to indicate that a respective locking mechanism is secured with the device;
a linking member coupled to the receiver base, the linking member configured to link the locking mechanism with an anchor point; and
a signal wire coupled to the receiver base and configured to communicate a signal corresponding to the indicator.

Abstract
A system and method for a locking mechanism that includes an ability to indicate proper engagement via a signal cable coupled through a harness. The locking mechanism may include electronic components including three magnetic actuators and corresponding electronic switches that signal change of state. Locking tabs and a leading edge of the insert respectively include the three magnetic actuators. The electronic switches, which may be magnetically activated reed switches, signal status change to an external controller and, optionally, an external computer. Further, status signals and power signals may be routed through a steel cable or woven nylon harness that coupled the locking mechanism to a local anchor point. Change of status notification may be important on critical safety worksites where lack of mechanical and electronic connection can be life threatening.

18. A method for providing safety to a worker, the method comprising:
-
in a human lift device, insert a personal safety harness device into locking mechanism having a linking member attached to an anchor point of the human lift device, sensing whether or not a plurality of indicator switches indicate that the insert is properly engaged with the locking mechanism through the linking member; and disengaging a local controller any one indicator switch in the locking mechanism indicates that the insert device is improperly engaged with the locking mechanism. - View Dependent Claims (19, 20)
