Description
MECHANICAL OVERRIDE OF AN ELECTRONIC LOCK
The present invention relates to electromechanical locks and blocking mechanisms therefore. More particularly, it relates to manual overrides of the blocking mechanism.
Background of the Invention
Federal Specification FF-L-2890B governs lock extensions and categorizes them as follows: pedestrian door preassembled locks (PDPL), pedestrian door lock assembly panic (PDLAP), and auxiliary deadbolts (ADB) for use with changeable combination locks and strikes. For each of these categories of extension, the specification defines types with key access control and types with keyless access control. Additionally, these extensions should be right and left hand interchangeable.
This invention was pursued to meet both the keyed and electronic access capabilities required per FF-26890B and be suitable for either right or left hand mounting. A single, reversible device with both access capabilities helps to optimize system design by minimizing components and packaging. The present invention can also be used in other high security lock applications where redundant access capabilities are desired.
Summary of the Invention
An electromechanical lock according to the present invention includes a lock extension and a blocking module having an interior region. A pivot bolt is mounted in the interior region for rotation about a rotation axis between a nominal position and an unsecured position. First and second blockers are also disposed in the interior for movement between their respective nominal positions and an unblocking position. The lock further includes an override disposed in the interior region for movement between a nominal position and an override position. The lock is in a secured condition when the first and second blockers and the override are in their respective nominal positions and an unsecured condition when the second blocker is in its unblocking position.

Detailed Description of the Drawings
As illustrated in Figure 1, a blocking module 10 is disposed adjacent a lock extension 12. The blocking module 10 includes a pivot bolt 14 that extends into the housing of the lock extension 12 to maintain the lock in a secured condition. The blocking module 10 and lock extension 12 would typically form an electromechanical safe lock and be housed in a metal (typically zinc alloy), rectangular case and enclosed by a stainless steel plate cover screwed to the case (not shown).
As illustrated in Figures 2-5, the blocking module 10 can include a housing 16 and cover 18 defining an interior region. The pivot bolt 14, a sliding blocker 24 and spin blocker 26 driven by motor 28 are mounted in the interior region. In addition, a manual override 32, including a drive gear 34, an idler gear 36, and drive pin gear 38, is positioned to drive a plunger 40. The drive gear includes a key-receiving slot 42 disposed along its rotational axis.
The pivot bolt 14 includes an integral spindle 22 that nests inside holes in the case and cover and is constrained to rotation about the spindle axis. The sliding blocker 24 is disposed in a channel 25 in the floor of the housing 16 and is constrained to move linearly in the channel 25. In preferred embodiments, the pivot bolt 14 is biased to a lock secured condition by a torsion spring 44. The sliding blocker 24 is biased by a compression spring 46 to block the pivot bolt 14 from pivoting to a lock unsecured condition. The spin blocker 26 is biased by a torsion spring 48 to prevent the sliding blocker 24 from releasing the pivot bolt 14.
The spin blocker 26 has a circular wedge 52 extending from its center as well as a lever 54 that extends in an opposing direction. The spin blocker's central, cylindrical body is pressed onto an electric motor shaft and the assembly is then placed in a recess in the housing 16 with the wedge 52 positioned toward the sliding blocker 24. The torsion spring 48 is applied to the spin blocker 26 to resist counter clockwise rotation as viewed from the output shaft side of the motor 28.
The spin blocker 26 lever extends away from the pivot bolt 14 and makes contact with a plunger 40. The plunger 40 has feet 56 that slide within grooves 58 in the housing 16. The plunger 40 includes a slot 60 in which the drive pin 62 of the drive pin gear 38 is inserted. The pin 62 is offset from the rotational axis of the drive pin gear 38 and travels an orbital path about this axis when the drive pin gear 38 rotates. This orbital motion of the pin 62 interacting with the slot 60 induces translation of the plunger 40 within the housing 16.
When secured, as illustrated in Figure 3, the pivot bolt 14 is extended, the sliding blocker 24 contacts the pivot bolt 14, and the spin blocker wedge 52 is in the path of the sliding blocker 24 to prevent it from sliding. Force on the pivot bolt 14 closes any gaps between the pivot bolt 14, sliding blocker 24, spin blocker 26 and pushes the spin blocker wedge 52 against the floor of the housing 16, thus resisting further movement of the pivot bolt 14.
To allow the pivot bolt 14 to retract into the blocking module 10, the spin blocker 26 must be rotated such that the spin blocker wedge 52 is moved out of the path of the sliding blocker 24 as illustrated in Figures 4-7. This movement can be achieved by two methods. In keyless access control, an electrical current is supplied to the motor 28, causing the spin blocker 26 to rotate and clear the path for the sliding blocker 24. Rotation of the spin blocker 26 is limited to -90° by lock structure. When motor current is stopped and the pivot bolt 14 returns to its extended position, the sliding blocker 24 and spin blocker 26 are returned to secured position by springs 46 and 48, respectively.
Figures 6A-6D illustrate the movement of the pivot bolt 14 and slide blocker 24 during retraction of pivot bolt 14 that results in the unsecured condition illustrated in Figure 5. Initially, an electrical current has been applied to the motor 28 to rotate the spin blocker 26
counterclockwise to the position best seen in Figure 6B. In Figure 6 A, an external force F is applied to the pivot bolt 14, urging it to rotate in a clockwise direction. As it rotates, it pushes the slide blocker 24 in the direction of arrow 64. The slide blocker 24 moves to the left, as seen in Figure 6B, into the space previously occupied by the spin blocker 26. In Figure 6C, the pivot bolt 14 is fully retracted and held by an external force and the sliding blocker 24 is prevented from returning to its nominal position. In Figure 6D, the sliding blocker 24 is preventing the spin blocker 26 from returning to its nominal position.
For keyed access control, illustrated in Figures 7A-7C, the user inserts a key into a lock cylinder (not shown) in the door and turns the key -90° in either direction. A flat spindle extending from the back of the lock cylinder is disposed in the drive gear slot 42, thereby
transferring the rotation of the user's key to rotation of the drive gear 34. The drive gear 34 transfers the rotary motion of the key, via the idler gear 36, to the drive pin gear 38. As noted above, the pin 62 on the drive pin gear 38 is disposed in the slot 60 formed in the plunger 40. As the drive pin 62 bears on the plunger slot 60, the plunger 40 translates toward the spin blocker 26, thereby pushing the lever 54 and lifting the spin blocker 26 out of the path of the sliding blocker 24. Thereafter, rotation of the pivot bolt 14 forces the slide blocker 24 into the space previously occupied by the spin blocker 26.
To secure the lock, the user must rotate the key back to home position were the key can be removed. All lock internal components will spring back to their respective nominal positions under the biasing forces of the torsion springs 44 and 48 and the compression spring 46. The plunger returns to its nominal position by the pin 62 acting on the slot 60 as the drive pin gear 38 rotates in response to the rotation of the key.
For either type of access control employed, movement of the pivot bolt is due to external forces applied by other components in the lock extension. Similarly, these same components must move back to their original position to allow the pivot bolt to rotate back to secured position. A micro switch within the lock assembly senses pivot bolt position and can provide this signal to the lock extension controls.
Advantageously, the present invention gives the lock two methods of access control and allows the end user to employ either or both in a given installation. In addition, the lock can be reversed to accommodate right or left handed door configurations. Key rotation in either direction results in the same necessary motion required for access. Further, packaging of lock internal components is efficient yet compatible with the industry standard high security lock foot print ("magic module") and smaller foot prints.
The above-described embodiment is not to be considered as limiting the breadth of the present invention. Modifications and other alternative constructions will be apparent that are within the spirit and scope of the invention as defined in the appended claims. For example, one variation might include the use of cams and levers in lieu of the gear train described above for the mechanical override.
