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.
  • the rapid collisions of gear teeth in a gear train caused by high acceleration can frequently damage the gear train and lead to improper operations of the lock mechanism.
  • the collisions of the gear teeth may also provide audible information that an unauthorized person can detect and use to determine the programmed combination that actuates the unlocking of the mechanism.
  • a locking mechanism 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 mechanism also includes a user input device for receiving user input information and a controller for verifying user input information with stored authentication information.
  • the controller 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.
  • the guide element engages the bolt retraction gear while moving from the non-capturing position to the capturing position for directing the bolt retraction gear to the disengagement position.
  • the actuator assembly further includes a cam movable between a first position and a second position, an actuator, and a clutch mechanism. The actuator engages the cam via the clutch mechanism. The cam is positioned adjacent to the guide element in the first position and engaged with the guide element in the second position. As such, the cam engages the guide element for moving the guide element between the capturing and non-capturing positions.
  • a locking mechanism 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 lock dial for receiving user input information, and a sensor configured to sense the rotation of the lock dial.
  • a display is configured to visualize the user input information, and a controller is configured for verifying user input information with stored authentication information. The controller is operatively connected to the sensor and the display for converting the rotation of the lock dial into the user input information visualized on the display via an algorithm. Upon verifying that the user input information matches the stored authorization information, the bolt retraction gear moves from the disengagement position to the engagement position with the manually-driven gear.
  • the user input information visualized on the display is generally random from the rotational position of the lock dial. Furthermore, the algorithm converts the rate of rotation of the lock dial into the user input information selected by a user.
  • a further embodiment of a locking mechanism includes a lock casing having interior components of a lock therein.
  • the lock casing is at least partially formed of a substantially translucent material.
  • the interior components of the lock are visible from exterior of the casing for showing evidence of lock tampering.
  • the lock casing further includes a first portion, which is opaque, and a second portion, which is substantially translucent. The first and second portions of the lock casing are permanently sealed together such that separating the first and second portions will damage at least a portion of the lock casing.
  • a method of operating a lock includes capturing the bolt retraction gear with the guide element in the capturing position to inhibit the movement of the bolt retraction gear toward engagement with the manually- driven gear.
  • the method also includes recording user input information from the user input device, and verifying that the user input information matches authorization information stored in the controller.
  • the method includes rotating the cam of the actuator assembly to engage the guide element and move the guide element to the non-capturing position.
  • the method includes disengaging the guide element from the bolt retraction gear to permit engagement of the bolt retraction gear with the manually-driven gear after the user input information has been verified.
  • the method also includes driving the lock bolt to the retracted position by manually driving the gear with the bolt retraction gear.
  • the method includes operating the actuator for a predetermined period of time in order to rotate the clutch mechanism for the predetermined period of time and engaging the clutch mechanism with the cam.
  • the method also includes seizing the movement of the cam while the actuator continues to operatively rotate the clutch

  • FIG. 1 illustrates one embodiment of a high security lock 10 coupled, for example, to a structure door 12, and including a lock casing 14 and a user input device 15.
  • the user input device 15 of this embodiment of the lock 10 is a mechanical lock dial 24 disposed within a dial housing 16.
  • a dust cover 18 may be coupled to the dial housing 1 6 in a removable manner using suitable snap-fit connectors 20, for example, and includes an aperture 22 through which the lock dial 24 extends.
  • the dial 24 may be rotated to input a numerical combination and, as will be explained below, the numbers of the combination are viewable through a window 26 in the dial housing 16 via a reflection in a mirror 28.
  • 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 1 6 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.
  • FIG. 4 illustrates a longitudinal cross-sectional view
  • the spindle shaft 52 is shown extending completely through the dial housing 1 6 and the lock casing 14.
  • One or more spindle sleeves 60 receive the spindle shaft 52 along its length. Such sleeves 60 will help prevent undesired entry into the lock casing 14 and access of the various bolt retraction hardware if the shaft 52 were to be removed.
  • the lock casing 14 is shown in exploded form to illustrate the circuit board 62 and various lock bolt retraction hardware, including a bolt guide member 64, the bolt 54, a bolt retraction gear 68, an actuator 70, a pivot block 72, and a cover 74 for fastening to the pivot block 72 and covering a rotating output element 76 of the actuator 70.
  • the lock casing 14 includes a front casing half 14a and a rear casing half 14b.
  • the circuit board 62 is placed on a front inner side of the front casing half 14a. Therefore, if a drill is used to drill into the lock casing 14 from outside of the door 1 2, the drill bit will first contact the circuit board 62 and likely disable the lock 10, thereby making entry more difficult.
  • a spindle gear 78 is coupled for rotation with the spindle shaft 52 and the connected dial 24 (FIG. 4).
  • the spindle gear 78 meshes with a first gear portion 80a of a drive gear element 80.
  • An opposite or second gear portion 80b of the drive gear element 80 extends through an aperture 82 in the rear casing half 14b, such that it may mesh with the bolt retraction gear 68 upon input of a correct combination code as shown in FIGS. 6 and 7.
  • An encoder 84 is used to detect input of combination codes via rotation of the shaft 52 and is used in conjunction with suitable controller circuitry on the circuit board 62.
  • 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 use of a dial plate portion 32 and mirror 28 allows for placement of the battery 48 in the dial housing 16 in a space efficient manner.
  • the lock casing portions 14a, 14b are mechanically fixed together, such that if they are pried apart, the mechanical elements (not shown) fixing the lock casing 14 together will break. It will be appreciated that the bolts 94 extending through the lock casing 14 do not fasten the lock casing portions 14a, 14b together, but merely serve to secure the lock casing 14 to, for example, a door 12.
  • Another manner of surreptitious entry into locks may involve using a hammer from the outside to force the spindle shaft 52 through the lock 10.
  • 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 lock 10 further includes a circuit breaker device 96.
  • the circuit breaker device 96 of the illustrated embodiment consists of a continuous conductive wire having a first end 96a and a second end 96b, each end 96a, 96b electrically connected to the circuit board 62.
  • the circuit breaker device 96 is connected integrally into the primary controller circuits for the lock 10 such that if the circuit breaker device 96 is broken, the lock 10 will become inoperable.
  • the circuit breaker device 96 is disposed adjacent to the spindle sleeve 60 that carries the spindle shaft 52 as the shaft 52 enters the lock casing 14.
  • 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.
  • the lock 1 10 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.
  • this embodiment of the lock 1 1 0 follows the same bolt retraction sequence illustrated in FIGS. 6-9C and described above, and the lock 1 10 includes a different lock bolt 1 12 and a retracting bolt shield 1 14.
  • the lock bolt 1 12 includes a slot 1 12a adapted to receive the pin 68b of the bolt retraction gear 68.
  • the lock bolt 1 12 further includes a pair of opposing recesses 1 12b used in the retracting bolt shield 1 14 as described in detail below, and also a bolt extension 1 12c.
  • the bolt extension 1 12c is coupled to the lock bolt 1 1 2 with threaded fasteners 1 16 that are disposed flush with the bolt extension 1 1 2c outer surface when the bolt extension 1 12c is placed on the lock bolt 1 1 2.
  • the bolt extension 1 1 2c has a thickness of about one-tenth (0.100) to three-sixteenths (0.1875) of an inch.
  • the bolt extension 1 12c can be added to the lock bolt 1 12 if necessary for the door 12 selected.
  • the lock bolt 1 12 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 1 10.
  • the lock 1 10 of the current embodiment includes the retracting bolt shield 1 14.
  • the lock 1 10 includes a modified bolt guide member 1 18.
  • the bolt guide member 1 18 continues to include a recess 1 18a and a curved slot 120 for engaging the pin 68b of the bolt retraction gear 68.
  • the bolt guide member 1 18 also has a pair of longitudinally-directed apertures 1 18b formed on opposing sides of the bolt guide member 1 1 8.

  • the circuit board 62 waits until the dial 24 is rotated such that the relief 318 in the spindle gear 312 faces the first drive gear portion 314a as shown in FIGS. 16B and 17B. Then the circuit board 62 sends a signal to the actuator 326, causing the shaft 324 and the drive gear 314 to rotate into engagement with both the spindle gear 312 and the bolt retraction gear 316 simultaneously as shown in FIGS. 16B and 1 7B.

Additionally, the front and rear casing halves 512a, 512b are also permanently sealed together with adhesive during manufacturing of the lock 510. As such, any attempt to separate the front and rear casing halves 512a, 512b will damage at least a portion of the lock casing 51 2 and indicate unauthorized entry into the lock 510.
  • the circuit board 514 is placed on a front inner side of the front casing half 51 2a. Therefore, if a drill is used to drill into the lock casing 51 2, the drill bit will first contact the circuit board 514 and likely disable the lock 510, thereby making entry more difficult.

  • the rotary sensor 530 is electrically connected to suitable controller circuitry on the circuit board 514.
  • the rotary sensor 530 is positioned adjacent to the encoder 528, which is a magnet. Because the rotary sensor 530 is close enough to the encoder 528 to sense the magnetic field of the magnet, the rotary sensor 530 detects the rotation of the drive gear element 80. In this respect, the position of the drive gear element 80 may directly or indirectly correlate to the position of the lock dial 24.
  • circuit board 514 operates an algorithm based on the rotation of the drive gear element 80 for converting the rotation of the lock dial 24 to user input information.

  • the actuator assembly 522 includes a guide element 536.
  • the guide element 536 is operatively movable between a capturing position and a non-capturing position. In the capturing position, the guide element 536 inhibits the movement of the bolt retraction gear 520, but, in the non-capturing position, the guide element 536 releases the movement of the bolt retraction gear 520.

Normally the guide element 536 would prevent rotation of the bolt retraction gear 520, as shown in FIG. 22A, for example. However, when the projection 542 of the cam 540 rotates and moves the guide element 536 toward the rear casing half 512b and slightly downward, as viewed in FIGS. 23A-23B, this allows the bolt retraction gear 520 to move or rotate clockwise as viewed in FIGS. 22A-22C, such that it may engage with the second portion 80b of the drive gear element 80.
  • the actuator assembly 522 also includes a clutch mechanism 544 for rotatably and resiliently coupling the cam 540 operatively to the actuator 538, as seen in FIG. 20 and FIG. 21 .

More particularly, the actuator 538 rotates the hub 546 and pivot stop 550 for more time than necessary to move the guide element 536 to seizure against the guide stop 568. Thus, the pivot stop 550 continues to rotate the clutch torsion spring 552 against the stationary cam 540, causing the clutch torsion spring 552 to wind tighter therebetween.
