Abstract
A control docking station system for controlling locking engagement between a first female member and a male member that together form a locking mechanism. The first female member is connected to a safety device. The male member can be locked to and released from the first female member. The system includes a controller configured to sense an unsafe interlock signal. A second female member is operably connected to the controller's housing. Each female member includes a receiver base and a pair of pivoting locking tabs that is engageable with a key-like projection on the male member. The male member may be unlocked from the first female member when the controller senses an interruption to the unsafe interlock signal or if the unsafe interlock signal is overridden. The male member may be docked in the second female member during safe circumstances and/or the safety device is unused.
