Definitions

  • the present invention relates generally to locks, and more specifically, to high security locks adapted for use in safes and other security structures or areas.
  • the structure typically includes a lock mechanism, and the structure is generally designed to be accessible only by a select few individuals who are entrusted with a predetermined combination code that facilitates the unlocking of the mechanism.
  • Unauthorized persons will use simple lock picking tools as well as sophisticated equipment that can apply high mechanical forces or an electric or magnetic field to the lock mechanism in order to manipulate the components within the lock mechanism.
  • US 6341513 discloses a two-in-one combination safe lock which includes a lock device and an electronic lock device in a box that is set on the side of a safe door with a lock device in a box that is set on the side of a safe door with a lock latch on the upper side.
  • a numeric dial and a circular pushbutton plate are disposed at the front side of the safe door and the wheel is connected to the mechanical lock device and the electronic lock device in the box by a shaft. By rotating the numeric dial or inputting the access code through the circular pushbutton plate, the mechanical lock device and the electronic lock device are moved to pull back the lock latch and open the safe door.
  • a locking mechanism in one embodiment, includes a lock bolt that moves between an extended position and a retracted position.
  • the lock bolt is coupled to a bolt retraction gear which is movable between an engagement position and a disengagement position. In the engagement position, the bolt retraction gear is engaged with a manually-driven gear.
  • the locking mechanism also includes a user input device for receiving user input information and a controller for verifying user input information with stored authentication information. Upon detecting valid user input information, the controller triggers an actuator assembly having a guide element, which is operatively movable between a capturing position and a non-capturing position. In the capturing position, the guide element inhibits the movement of the bolt retraction gear. In the non-capturing position, the guide element releases the movement of the bolt retraction gear. The guide element inhibits the movement of the bolt retraction gear toward the engagement position until the controller verifies that the user input information matches the stored authorization information.
  • FIG. 2 illustrates an exploded view of the user input device 15 and its contents.
  • the dial 24 includes a protruding portion 30 which may be manually gripped by a user, and a plate portion 32 that includes the numerical combination numbers 34 on the backside thereof (see FIG. 3 ).
  • a brass insert 36 is rigidly secured to the dial 24 using screw fasteners 38.
  • the brass insert 36 can provide weight for the dial 24 and serve a bearing member for rotation against a portion 40 of the dial housing 16.
  • the dial housing 16 includes windows 42, 44 for allowing the numbers on the back side of the dial plate portion 40 to be viewed via a reflection in the mirror 28.
  • An LED indicator light 46 is provided and may be used in various manners to provide indication of combination input.
  • FIG. 3 illustrates a rear perspective view of the lock 10 and illustrates a lock bolt 54 extending from the lock casing 14.
  • the shaft 52 extends through a back side 56 of the lock casing 14 and is secured with a nut 58 in such a manner as to allow rotation of the shaft 52 when the dial 24 is rotated.
  • the back side of the dial plate portion 32 includes combination numbers, which, when reflected in the mirror 28 ( FIG. 2 ) will be viewable by the user.
  • the actuator 70 Upon entry of the correct combination code as recognized by the encoder and controller circuitry, the actuator 70 will be activated such that its output element 76 rotates.
  • the output element 76 includes a pin 76a that will rotate through a slot 86 in the pivot block 72 ( FIG. 5 ) and also move through a slot 68c in the bolt retraction gear 68. Normally this pin 76a would prevent rotation of the bolt retraction gear 68, as shown in FIG 8A , for example.
  • the bolt retraction gear 68 is slightly spring-loaded, with, for example, a torsion spring of low spring force, such that the bolt retraction gear 68 is biased in the clockwise direction to the position shown in FIG. 8B upon activation of the actuator 70.
  • the dial 24 may be manually rotated such that the drive gear element 80 is rotated through engagement of the first drive gear portion 80a with the spindle gear 78.
  • the spindle gear 78 is coupled to the shaft 52 by a key 88.
  • the bolt retraction gear 68 When the bolt retraction gear 68 is engaged with the drive gear portion 80b as shown in FIG. 8B , the bolt retraction gear 68 will rotate about its pivot axis 68a, and a pin 68b secured to the bolt retraction gear 68 will rise out of a position seated in a recess 64a of the bolt guide member 64 and the end 90a of a curved slot or pin guide 90 of the bolt guide member 64 ( FIG. 5 ).
  • the pin 68b also extends through a slot 54a in the bolt 54, and as the bolt retraction gear 68 rotates, the pin 68b rides upwardly in the slot 54a as viewed in FIGS. 8B and 8C and simultaneously moves the bolt 54 into the lock casing 14 and through the bolt guide member 64. Rotating the dial 24, shaft 52, and gears 78, 80, 68 in the opposite direction will extend the bolt 54 back to its fully-extended position and the bolt retraction gear 68 will be returned to the initial position shown in FIG. 8A by the pin 76a.
  • the output element 76 is spring-loaded by use of a spring 92 such that when the actuator 70 is deactivated, the spring 92 will return the pin 76a to the initial position shown in FIG. 9A , and the spring force of the output element 76 is sufficiently strong to force the bolt retraction gear 68 to the initial position shown in FIG. 8A .
  • the actuator 70 is a servo motor 70 in the illustrated embodiment.
  • the use of the servo motor 70 such as a micro-servo as opposed, for example, to a stepper motor, has advantages.
  • the servo motor 70 includes a relatively complex gear train that involves several revolutions in order to rotate the output element 76 through just a partial rotation as discussed above.
  • the servo motor 70 would be difficult to activate in some surreptitious manner.
  • the pin 68b used on the bolt retraction gear 68 rests in a recess in its home position with the lock bolt 54 extended as shown in FIG.
  • the circuit breaker device 96 is illustrated as a coil in FIG. 10 , the coil being wrapped around the spindle sleeve 60.
  • the circuit breaker device 96 may also comprise a plurality of wires.
  • FIGS. 11-14C another embodiment of a lock 110 is illustrated.
  • the lock 110 includes many of the same elements as the first embodiment of the lock 10, such as the circuit board 62, bolt retraction gear 68, and actuator 70.
  • reference numerals remain the same for similar elements in the various embodiments described.
  • This embodiment of the lock 110 follows the same bolt retraction sequence illustrated in FIGS. 6-9C and described above, and the lock 110 includes a different lock bolt 112 and a retracting bolt shield 114.
  • the lock bolt 112 includes a slot 112a adapted to receive the pin 68b of the bolt retraction gear 68.
  • the bolt extension 112c can be added to the lock bolt 112 if necessary for the door 12 selected.
  • the lock bolt 112 can be configured for use with any type of door.
  • the mounting bolts 94 of the lock casing 14 are accessible from the back side 56 of the lock casing 14. An unauthorized person having access to this rear side 56 could remove the mounting screws 94 and replace the lock casing 14 with a lock body of a different mechanism, thereby compromising the lock 110.
  • the lock 110 of the current embodiment includes the retracting bolt shield 114.
  • the lock 110 includes a modified bolt guide member 118.
  • the bolt guide member 118 continues to include a recess 118a and a curved slot 120 for engaging the pin 68b of the bolt retraction gear 68.
  • the bolt guide member 118 also has a pair of longitudinally-directed apertures 118b formed on opposing sides of the bolt guide member 118. These longitudinally-directed apertures 118b are in communication with laterally-directed slots 118c, the slots 188c extending from an edge of the bolt guide member 118 to longitudinal receptacles 122 holding the mounting bolts 94.
  • the retracting bolt shield 114 includes a blocking member 124 with a non-circular aperture 124a, a first member 126 with a non-circular aperture 126a, and a non-circular drive rod 128 operatively coupling the blocking member 124 to the first member 126 at the non-circular apertures 124a, 126a.
  • the drive rod 128 is positioned within one of the longitudinally-directed apertures 118b of the bolt guide member 118 while the blocking member 124 is at least partially disposed in one of the lateral slots 118c, as most clearly shown in FIG. 13 .
  • the drive rod 128 and associated apertures 124a, 126a are hexagonal in the illustrated embodiment, but one skilled in the art will appreciate that any alternative non-circular shape may be chosen for these elements.
  • the first member 126 has a first end 126b configured to engage the lock bolt 112 and more specifically, one of the recesses 112b in the lock bolt.
  • the recesses 112b force the first members 126 to rotate to the position shown in FIG. 14C .
  • the drive rods 128 have transferred the motion of the first members 126 to the blocking members 124 to reveal the mounting bolts 94.
  • the spindle gear 78 drives the bolt retraction gear 68 and lock bolt 112 back to an extended or locked position, the first members 126 again engage the lock bolt recesses 112b and rotate back to the position in FIG. 14A .
  • the retracting bolt shield 114 prevents an unauthorized person attempting to tamper with the lock 110 by removing the mounting bolts 94.
  • the bolt retraction gear 216 remains engaged with the second drive gear portion 214b when the lock bolt 54 is fully extended as shown in FIG. 15A .
  • a two-tooth relief 218 is provided on the spindle gear 212 and a corresponding two-tooth relief 220 is provided on the first drive gear portion 214a.
  • the relief 220 in the first drive gear portion 214a is oriented as shown in FIG. 15A to prevent engagement of the spindle gear 212 and the drive gear 214 while the spindle gear 212 is rotated during combination entry. Thus, no audible information from gear collisions is provided to an unauthorized person rotating the dial 24.
  • FIGS. 16A-17C An additional embodiment of the lock 310 is illustrated in FIGS. 16A-17C .
  • the lock 310 is similar to the lock 210 of the previous embodiment and includes a spindle gear 312, a drive gear 314 having a first drive gear portion 314a adapted to engage the spindle gear 312 and a second drive gear portion 314b, and a bolt retraction gear 316 adapted to engage the second drive gear portion 314b.
  • the spindle gear 312 and first drive gear portion 314a are also provided with corresponding two-tooth reliefs 318, 320 in the same manner as explained above with respect to lock 210.
  • the actuator 70 and associated output element 76 have been removed.
  • the gear advance lever 578 extends to and engages a notch portion 584 of the bolt retraction gear 520. As such, when the bolt retraction gear 520 is in the disengagement position, the bolt retraction gear 520 forces against the gear advance lever 578 and winds the kicker torsion spring 574 tighter as shown in FIG. 22A . In contrast, FIG. 22B shows that as the guide element 536 moves toward the non-capturing position, the gear advance lever 578 directs the bolt retraction gear 520 into the engagement position with the drive gear element 80. Finally, the stop lever 580 engages the rear casing half 512b for halting the rotation of the drum body 572 at a position for re-engaging the bolt retraction gear 520 while moving from the engagement position to the disengagement position.
  • FIGS. 24A-24C show the bolt retraction gear 520 moving respectively from the disengaged position to the engaged position as described above.
  • the pivot arm 558 clears the cam arm 554 to rotate the clutch torsion spring 552 and, in turn, rotate the projection 542 of the cam 540 into the guide element 536.
  • the bolt retraction member 520 also includes a beveled edge 588 that cooperates with a curved end portion 590 of the transverse portion 564. While the curved end portion 590 moves from the capturing position to the non-capturing position, the transverse portion 564 effectively releases the biased movement of the bolt retraction gear 520 as the beveled edge 588 falls off of the curved end portion 590.
  • the curved end portion 590 moves to the beveled edge 588. Once reaching the beveled edge 588, the curved end portion 590 engages the beveled edge 588 to direct the bolt retraction gear 520 to the disengagement position.
  • the guide element 536 will overcome the biasing force of the biasing device 524 on the bolt retraction gear 520 to return the bolt retraction gear to the initial position shown in FIG. 22A .
