Definitions

  • This invention relates to a security lock assembly which is especially suitable for doors.
  • a lock assembly comprising a movable lock bolt, a striker unit adapted for mounting in a door jamb, which unit defines a cavity to receive said lock bolt, latch means mounted for movement to an operative position protruding into said cavity in which the latch means is engageable with the bolt when therein to prevent its withdrawal from the cavity, means to drive the latch means to said operative position, and a switch mounted on the striker unit and responsive to receipt of the bolt in the cavity to activate the drive means.
  • a lock assembly of the type above in which the assembly is characterized in that the switch is a magnetically operable switch mounted behind a bounding wall of the bolt cavity, and the lock bolt has a magnetized element therein for operating the switch.
  • the magnetically operable switch mounted behind the bounding wall of the bolt cavity may, for example, comprise a reed switch, and may be advantageously encased in a solid medium behind the bounding wall.
  • the reed would typically then be movable in a small elongate hollow in the medium.
  • the bolt is provided therein with a magnetized element, and preferably the element is encased in a spherical or cylindrical core within the bolt.
  • the core may be rotatably disposed within the bolt to thwart cutting through of the bolt and/or removal of the magnetized element.
  • Said structure may comprise a metal striker plate with a rectangular bolt cavity to receive the lock bolt of a deadbolt mechanism.
  • the movable latch means engageable with the bolt may be a pin, rod or the like, e.g. a cylindrical rod, adapted to engage in a hole in the bolt and preferably arranged so that it tends to fall from the bolt cavity under gravity unless held in its operative position.
  • a suitable helical spring may be provided to augment the gravity bias on the rod.
  • the drive means preferably includes a solenoid which is energizable, preferably in response to receipt of the bolt lock in the cavity, to drive the latch means, directly or indirectly, into locking engagement with the bolt and to retain it in such locking engagement.
  • the illustrated security lock assembly fitted to a door leaf 6 and door jamb 8, includes a deadbolt latch mechanism 12, having a rectangular bolt 14, in leaf 6, and a striker assembly 16 defining a striker plate 18 and bolt cavity 20, manufactured as a single unit adapted for mounting in the jamb 8. Screw holes 16a are provided for this purpose.
  • Deadbolt latch mechanism 12 is of a conventional construction apart from the bolt 14 and, except for this aspect which will be detailed hereinafter, will not be further described.
  • Striker plate 18 is of L-section steel.
  • Bolt cavity 20 is defined by a box protrusion 22 cast integrally with the striker plate.
  • the narrower flange 19 of plate 18 carries the usual bolt lead ramp 24 adjacent cavity 20.
  • the bolt locking apparatus which constitutes a preferred embodiment of the invention, is mounted behind the striker plate 18.
  • the principal components of the apparatus include latch means comprising a slidable bolt locking pin 26, a drive solenoid 28 for the pin, a pair of reed switches 30, 50 encased in a solid resin medium 32 at the rear of bolt cavity 20, and a switching relay 34 operated by reed switch 30 for setting the state of the solenoid and thereby the position of pin 26.
  • Reed switch 30, relay 34 and solenoid 28 together constitute means responsive to receipt of the bolt in the cavity to drive pin 26 to an operative position in the cavity in engagement with the bolt 14 to prevent withdrawal of the bolt from the cavity.
  • electrical wiring connections are not fully detailed in the drawings, although the leads for reed switches 30, 50 are depicted at 43.
  • reed switches 30, 50 comprise respective reeds 31, 51 in elongate hollows 33, 53 extending between contact sets 35, 55 cast in medium 32.
  • Medium 32 is fixed behind a back plate 36 for cavity 20 provided by a bracket 38 ( Figure 3).
  • Bracket 38 is adjustably mounted by small bolts 39 to a plate 40 projecting integrally from striker plate 18 adjacent cavity 20.
  • Media 32 is adhered to bracket 38 and is further retained by return lugs 42 at the top and bottom of plate 36.
  • Reeds 31, 51 are of a magnetically sensitive metal and are operated, to open the contacts 35, 55, by a magnetized slug 44 ( Figures 1 and 6) in bolt 14.
  • Slug 44 is encased in a spherical core 46, which is in turn freely rotatable with all degrees of freedom, in a complementary cavity in the bolt so that any cutting implement applied to the bolt will in due course strike the sphere and indefinitely rotate it rather than cut it through.
  • the core 46 thus thwarts both cutting of the bolt and removal of the magnetized slug.
  • Pin 26 is one of a pair 26, 27 fixedly coupled by a horizontal plate 48.
  • the pins are firmly but freely slidable through respective apertures in a rearwardly projecting flange 61a behind striker plate 18.
  • Pin 26 projects through a matching aperture 25 in box 22 and is slidable upwardly to an operative position in which it firmly engages in a complementary hole 56 in the underside of bolt 14.
  • a helical compression spring 62 about pin 26 between box 22 and plate 48 augments the gravity bias.
  • the space above cavity 20 is occupied by a small circuit board 66 with multi-point connector 68 and the aforementioned relay 34.
  • the contact set 35 of reed switch 30 is connected for operating relay 34.
  • the contact set 55 of reed switch 50 is coupled via connector 68 to a remote central monitoring control, not shown, at which the state of the reed switch would be indicated in any suitable manner, such as by a light.
  • a third reed switch 70 is mounted to plate 40 under bracket 38 but is mechanically rather than magnetically operated.
  • the external reed 72 of this switch is engaged by plate 48 as it nears the top of its upward travel and reed switch 70 may thus be employed to indicate at the remote control that pin 26 is in an operative, bolt engaging position.
  • the security provisions do not prevent opening the door in an emergency.
  • the power may be simultaneously withdrawn from the solenoids of all doorways to permit the withdrawal of the respective bolts from their striker cavities.
