Corner bolt locking system
A corner bolt locking system for a safe or vault is disclosed for use with cam and link locking mechanisms and a generally rectangular door panel frame, having a corner hole through its corner. A reinforcement channel is disposed at the corner and aligned with the corner hole. A corner bolt link arm is pivotably attached to a rotatable pin cam plate, and a corner bolt is pivotably attached to the corner bolt link arm and positioned through the reinforcement channel and the corner hole.
1. A locking system for a door, comprising:
a generally rectangular door panel frame defining a corner hole through at least one corner of the door panel frame;
a reinforcement channel disposed at the at least one corner and aligned with the corner hole;
a corner bolt link arm pivotably attached to a rotatable pin cam plate;
a corner bolt pivotably attached to the corner bolt link arm and positioned through the reinforcement channel and the corner hole; and
a pin bar having locking pins positioned proximate the door panel frame and pivotably attached to a pin bar link arm, the pin bar link arm being pivotably attached to the pin cam plate, the pin cam plate comprising a link arm attachment point to which both the corner bolt link arm and the pin bar link arm are pivotably attached.
2. The locking system of claim 1 , wherein the reinforcement channel comprises at least one surface defining a reinforcement hole that is aligned with the corner hole.
3. The locking system of claim 1 , wherein the reinforcement channel comprises two generally parallel and spaced apart surfaces, each of the surfaces defining a reinforcement hole that is aligned with the corner hole.
4. The locking system of claim 3 , wherein the reinforcement channel comprises a U-shaped channel having tapered edges to fit into the at least one corner of the door frame.
5. The locking system of claim 1 , wherein, when the pin cam plate is rotated, the corner bolt is movable between a locked position wherein an outer end of the corner bolt extends past an outer edge of the at least one corner of the door frame and an un-locked position wherein the outer end of the corner bolt is unextended.
6. The locking system of claim 5 , wherein the outer end of the corner bolt is chamfered such that the outer end of the corner bolt is shaped similarly to the outer edge of the at least one corner of the door frame.
7. The locking system of claim 1 , wherein the corner bolt comprises a threaded interior end attached to one side of an L-shaped bracket, the other side of the L-shaped bracket being pivotally attached to the corner bolt link arm.
8. The locking system of claim 4 , wherein the space between the two generally parallel and spaced apart surfaces is approximately ½ inch to 5 inches.
9. The locking system of claim 4 , wherein the reinforcement channel is welded to the door panel frame and to the door panel.
10. The locking system of claim 1 , wherein the corner bolt comprises a threaded interior end attached to a first perpendicular surface of an L-shaped angle plate, said L-shaped angle plate having a second perpendicular surface which is facing and substantially near the surface of the door, thereby assisting in preventing pry attacks.
11. A door for a safe or vault, comprising:
a generally rectangular door panel frame defining a corner hole through at least one corner of the door panel frame;
a U-shaped reinforcement channel disposed at the at least one corner of the door panel frame, the channel comprising two generally parallel and spaced apart surfaces, each of the surfaces defining a reinforcement hole that is aligned with the corner hole of the door panel frame, the channel having tapered edges to fit into the at least one corner;
a corner bolt link arm pivotably attached to a rotatable pin cam plate; and
a corner bolt pivotably attached to the corner bolt link arm and positioned through the reinforcement channel and the corner hole.
12. The door of claim 11 , wherein, when the pin cam plate is rotated, the corner bolt is movable between a locked position wherein an outer end of the corner bolt extends past an outer edge of the at least one corner of the door frame and an un-locked position wherein the outer end of the corner bolt is unextended.
13. The door of claim 12 , wherein the outer end of the corner bolt is chamfered such that the outer end of the corner bolt is shaped similarly to the outer edge of the at least one corner of the door frame.
14. The door of claim 11 , further comprising:
a pin bar having locking pins, positioned proximate the door panel frame and pivotably attached to a pin bar link arm, the pin bar link arm being pivotably attached to the pin cam plate.
15. The door of claim 14 , wherein the pin cam plate comprises a link arm attachment point to which both the corner bolt link arm and the pin bar link arms are pivotably attached.
16. The door of claim 11 , wherein the corner bolt comprises a threaded interior end attached to one side of an L-shaped bracket, the other side of the L-shaped bracket being pivotally attached to the corner bolt link arm.
17. The door of claim 11 , wherein the corner bolt comprises a threaded interior end attached to a first perpendicular surface of an L-shaped angle plate, said L-shaped angle plate having a second perpendicular surface which is facing and substantially near the surface of the door, thereby assisting in preventing pry attacks.
18. A locking system for a door, comprising:
a generally rectangular door panel frame defining a corner hole through at least one corner of the door panel frame;
a reinforcement channel disposed at the at least one corner, the reinforcement channel having tapered edges to fit into the at least one corner and comprising two generally parallel and spaced apart surfaces, each of the surfaces defining a reinforcement hole that is aligned with the corner hole;
a corner bolt link arm pivotably attached to a rotatable pin cam plate; and
a corner bolt pivotably attached to the corner bolt link arm and positioned through the reinforcement channel and the corner hole.
19. The locking system of claim 18 , further comprising:
a pin bar having locking pins, positioned proximate the door panel frame and pivotably attached to a pin bar link arm, the pin bar link arm being pivotably attached to the pin cam plate.
20. The locking system of claim 19 , wherein the pin cam plate comprises a link arm attachment point to which both the corner bolt link arm and the pin bar link arms are pivotably attached.
21. The locking system of claim 18 , wherein the corner bolt comprises a threaded interior end attached to one side of an L-shaped bracket, the other side of the L-shaped bracket being pivotally attached to the corner bolt link arm.
22. The locking system of claim 18 , wherein the corner bolt comprises a threaded interior end attached to a first perpendicular surface of an L-shaped angle plate, said L-shaped angle plate having a second perpendicular surface which is facing and substantially near the surface of the door, thereby assisting in preventing pry attacks.
