Abstract

A lock assembly and locking systems adapted for use with hinged bidirectional hardened plastic doors is provided. The lock assembly comprises a moveable bolt arranged within a housing and a having a first perimeter; a strikeplate spaced apart from the housing and having a hole with a second perimeter; and an actuator adapted to move the bolt form an unlocked position where the bolt is within the housing to a locked position where a portion of the bolt extends into the hole, wherein the second perimeter is 2-10 times greater than the first perimeter such that the hinged double-acting impact-traffic door has an amount of play when the bolt is in the locked position.

Claims

1. A lock assembly, comprising:

a moveable bolt arranged within a housing and a having a first cross-sectional length;

a strikeplate spaced apart from the housing and having a hole with a second length; and

an actuator adapted to move the bolt from an unlocked position where the bolt is within the housing to a locked position where a portion of the bolt extends into the hole,

wherein the second length is 3-10 times greater than the first length such that the difference between the second length and the first length provides for an amount of play between the bolt and the strikeplate when the bolt is in the locked position.

2. The lock assembly of claim 1, wherein the first cross sectional length is a major length about 0.1-2 inches.

3. The lock assembly of claim 2, wherein the bolt has a diameter of about 0.5-1 inch.

4. The lock assembly of claim 1, wherein the bolt is arranged substantially within the housing.

5. The lock assembly of claim 1, wherein the hole has a diameter second length is a major length about 0.5-5 inches.

6. The lock assembly of claim 1, wherein the hole has a diameter of about 1-3 inches.

7. The lock assembly of claim 6, wherein the bolt has a diameter of about 0.5 inch and the strikeplate has a diameter of about 2 inches.

8. The lock assembly of claim 1, amount of play is generally horizontal to a floor.

9. The lock assembly of claim 1, wherein a plurality of strikeplates are stacked to increase the depth of the hole.

10. The lock assembly of claim 1, wherein when the bolt is in the locked position the amount of play that a door has is at least 1 inch when pushed or pulled.

11. A lock assembly adapted for use with a hinged double-acting impact-traffic door, comprising:

a moveable bolt arranged within a housing and a having a first radial length and a second radial length;

a strikeplate spaced apart from the housing and having a hole with a first radial length and a second radial length, the first or second radial length of the hole being 2-10 times greater than the first or second radial length of the bolt; and

an actuator adapted to move the bolt from an unlocked position where the bolt is within the housing to a locked position where a portion of the bolt extends into the hole, wherein when the bolt is in the locked position the hinged double-acting impact-traffic door can be pushed or pulled at least 0.5 inch without the bolt exterior contacting the hole interior.

12. The lock assembly of claim 11, wherein when the bolt is in the locked position the door can be push or pulled up to 6 inches without being bent.

13. The lock assembly of claim 12, wherein when the bolt is in the locked position the door can be pushed or pulled up to 4 inches without being bent.

14. A locking system adapted to lock and unlock a hinged double-acting impact-traffic door, comprising:

a lock assembly comprising a lock portion with a moveable bolt having a first perimeter and a strikeplate portion with a hole having a second perimeter, the second perimeter being greater than the first perimeter;

a controller adapted to direct the locking and unlocking of the hinged double-acting impact-traffic door;

a bolt position sensor adapted to provide an electronic signal to the controller indicative of the position of the bolt; and

an actuator electronically interconnected to the controller adapted to move the bolt as directed by the controller, wherein when the door is locked, the bolt is advanced into the hole and the door can be moved at least 1 inch without being bent.

15. The lock assembly of claim 14, wherein the second perimeter is 2-10 times greater than the first perimeter such that the hinged double-acting impact-traffic door has an amount of play when the bolt is in the locked position.

16. The lock assembly of claim 14, wherein the second perimeter is a diameter of about 2 inches and the first perimeter is a diameter of about 0.5 inch.

17. The lock assembly of claim 14, wherein the actuator is a solenoid.

18. The lock assembly of claim 14, wherein the controller is located within a control console near the door.

19. The lock assembly of claim 14, wherein the controller is electronically interconnected to a plurality of components selected from the group consisting of:

exit button, motion detector, remote control receiver, power supply, and ID card reader.

20. The lock assembly of claim 19, wherein the door serves as a partition between an interior and exterior of a building, and an exit button, motion detector or remote control receiver is located within the interior of the building near the door.
