ABSTRACT:
A security system for cargo loading doors, comprising: a substantially narrow profile housing adapted to being connected to an inside of a cargo loading door; an actuator having a key receptacle, for moving a latch structure between a locked position and an unlocked position; the latch structure and the actuator being coupled by a linkage mechanism and plunger assembly, the latch structure is adapted to be at least partially received in a header of at least one of a cargo carrying enclosure, such as an ISO container, domestic container, semi-trailer and the like, when the latch structure is in the locked position and withdrawn from the header when the latch structure is in the unlocked position; and the linkage mechanism includes a distal section and a proximal section connected by a middle pivot pin, the distal section is coupled to the latch structure with an upper pivot pin and the proximal section is coupled with the plunger assembly, the proximal section is also pivotably connected to the housing with a stationary pivot pin, the linkage mechanism defines a simulated rigid link defined by the proximal section and distal section being substantially aligned when the latch structure is in the locked position.
