A locking apparatus for securing a door or window to a receiving structure, comprising:
- said locking apparatus attachable to a door or window, and said locking apparatus comprising:
- a locking pin having a distal end, said locking pin attached to a slide car via a locking pin attachment, and wherein said slide car is slidably engaged with a base plate, said base plate for attaching said locking apparatus to said door or window, wherein said slidable car is translatable along said sliding engagement;
- wherein, when said locking apparatus is attached to a door or window, said base plate is held in a fixed position relative to said door or window;
- and
- wherein, when said door or window is a closed state, said locking apparatus is able to receive a pin locking tab;
- and
- wherein said locking pin is able to be motivated towards said pin locking tab such that said locking pin is received by a pin receiving opening, resulting in a locked state;
- and
- wherein said locking pin is able to be motivated away from said pin locking tab such that no portion of said locking pin is received by said pin receiving opening, resulting in an unlocked state;
- wherein said sliding car and said base plate are subject to an expanding force between them tending to motivate said sliding car along said slidable engagement, said expanding force tending to translate said locking pin distal end towards said pin receiving opening;
- wherein said locking pin attachment to said slide car is via a controllable actuator, and wherein said locking pin is attached to an extendable portion of said controllable actuator that is able to be extended or retracted upon command, such that said controllable actuator is operable to motivate said locking pin into said pin receiving opening upon command by extending said extendable portion, placing said locking apparatus into said locked state;
- and wherein said controllable actuator is operable to motivate said locking pin out of said pin receiving opening upon command by retracting said extendable portion, placing said locking apparatus into said unlocked state;
- further comprising a rotatable knob attached to a rotatable shaft, and wherein said rotatable shaft is attached to an override mechanism such that, when said locking apparatus is in said locked state, a rotation of said rotatable knob in a first direction of rotation is operable to motivate said slide car along its slidable engagement with said base plate against said expanding force such that said locking pin is motivated out of said pin receiving opening, placing said locking apparatus in an override state;
- and wherein when said locking apparatus is in an override state, rotation of said rotatable knob in a second direction of rotation that is opposite said first direction of rotation allows said expanding force to motivate said locking pin into said pin receiving opening, placing said locking apparatus in said locked state.
