Patent number: 6298699Abstract: An electronic combination lock having a dial-shape handle with a keypad incorporated therein is disclosed. Rotation of the handle extends or retracts a bolt that closes or opens the lock. The keypad includes indicia that give the user visual cues as to the orientation of the handle, thereby informing the user of the extended or retracted condition of the bolt. A battery pack is used to energize circuitry that recognizes a code entered through the keypad. The circuitry provides a control signal that activates a solenoid to extend or retract a bolt blocking device, which in turn prevents or enables movement of the bolt. A visual indicator warns of a low voltage or power condition in the battery pack. Electrical contacts are provided in the face plate of the handle to connect the circuitry to an external power source in case the battery pack fails.Type: GrantFiled: July 7, 2000Date of Patent: October 9, 2001Assignee: U-Code, Inc.Inventors: Klaus W.

Patent number: 6297725Abstract: A keyless locking mechanism is activated by a remote unit which transmits coded signals to an electromechanical door lock device. The electromechanical device components are configured for secure mounting within the void or hollow portions of existing door locking apparatus. A sensor in the outer doorknob receives and forwards the coded signals to a processor which compares them with a predetermined stored signal. If an acceptable comparison is made, the processor generates control signals for the device, which acts solely along the locking axis to enable or disable the door locking assembly. The coded signals include two separate signals which are transmitted in segments interleaved with one another. The first signal includes an entrance code, while the second signal provides information concerning the frequency over which the next segments will be transmitted. The processor uses the second signal information to tune the receiver.Type: GrantFiled: June 21, 1999Date of Patent: October 2, 2001Assignee: Schlage Lock CompanyInventors: Andrew Tischendorf, Kenneth Schultz, Gary Lehman, Demos Andreou, Ari Glezer

Patent number: 6212923Abstract: A dead bolt lock automatically blocks the extended bolt to prevent externally-applied force from thrusting the bolt back into the lock case, and in the event of physical attack the lock responds by prolonging or perpetuating the dead bolt blocking condition. A push-pull lock has a bolt whose motion in both directions is stopped in response to detection of a rise in motor current above a certain level: a cushioning arrangement allows the current-limiting feature to be implemented without risk of damage to the motor, gear teeth or other drive components. A re-locker arrangement includes an angled flange that is part of a motor-supporting bracket; when forcibly pressed, the flange breaks plastic pins to release a spring-biased re-locker wire to block the bolt from being withdrawn, and when the wire is in the dead bolting position an extension of the re-locker wire engages a ridge in the lock's case to prevent the re-locker from being manipulated back to its original position.Type: GrantFiled: July 27, 1998Date of Patent: April 10, 2001Assignee: Sargent & Greenleaf, Inc.Inventor: Michael R.

Patent number: 6181025Abstract: An integrated, flexible interrogator-coil circuit provides security for the type of lock opened by a key that transmits a coded signal to an interrogator circuit associated with the lock. When the key is inserted into the lock, a coil in the key is brought into proximity with an energized coil associated with the lock. The resulting current induced in the key's coil causes the key to transmit the coded signal. If the coded signal is recognized by the lock's interrogator circuit, the key opens the lock. The lock coil is an etched metallic spiral on a loop portion of the circuit board and the interrogator circuit components are mounted on a base portion of the circuit board on which is etched a metallic circuit pattern. The integrated interrogator-coil circuit is faster and more economical to manufacture. Because the circuit is on a flexible circuit board, it can be made a part of the lock assembly itself, thus facilitating use of this type of security system.Type: GrantFiled: May 21, 1999Date of Patent: January 30, 2001Assignee: Lear CorporationInventors: John E. McConnell, Eric Krupp

Patent number: 6178791Abstract: The technique for electronically resetting a magnetically sealed solenoid to an unattracted, unactuated position is described for use with solenoids which have either a residual magnetic or a permanent magnet holding force necessary to retain the armature of the solenoid in its actuated position until such time as the armature is either physically displaced by a mechanical force or an electronic signal is applied to the solenoid. This displacement creates a reverse polarity magnetic field, effectively overcoming the magnetic field acting to hold the armature in its actuated position, permitting a small mechanical force to reset the armature. In order to prevent a lock or similar device from being conditioned for opening and possibly left in that condition for a significant period of time while unattended, jeopardizing the security of the container and its contents, the actuation of the armature in the reset or release phase may occur a relatively short time following its actuation.Type: GrantFiled: December 28, 1999Date of Patent: January 30, 2001Assignee: Mas-Hamilton Group, Inc.Inventors: James D. Hill, William Fain Irving, James Thomas Loiselle, Joseph W. Luciano, Kenneth H. Mimlitch, John E. Passafiume
