Patent number: 6295849Abstract: An electronic combination lock is disclosed which allows access to a closed or secure location wherein the lock includes a locking mechanism for operating between a locked condition and an unlocked condition. A rotatable cam wheel has a circumferential surface portion defining a slot such that rotation of the cam wheel moves the slot. A movable lever is coupled to the locking mechanism for changing the condition of the locking mechanism from the locked condition to the unlocked condition and is pivotably movable into and out of engagement with the cam wheel. The movable lever engages the cam wheel such that rotation of the cam wheel changes the condition of the locking mechanism. A cantilever and detent on the lever releasably maintain the lever in a position disengaged from the cam wheel.Type: GrantFiled: July 13, 1998Date of Patent: October 2, 2001Assignee: Masco CorporationInventors: Klaus W. Gartner, Larry I. Cutter, Peter J. Phillips

Patent number: 6116066Abstract: 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: March 29, 1996Date of Patent: September 12, 2000Inventors: Klaus W. Gartner, Dieter Butterweck, Peter J. Phillips

Patent number: 5845523Abstract: 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. In one embodiment, a gear rotated by the shaft displaces the rack end of radially-extending bolts that extend or retract. The keypad includes indicia that inform the user of the extended or retracted condition of the bolt. A battery pack is used to energize circuitry, and 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 31, 1996Date of Patent: December 8, 1998Assignee: U-Code, Inc.Inventors: Dieter Butterweck, Peter J.

Patent number: 5594430Abstract: A programmable time lock includes a microprocessor, which senses the angular position of a key shaft via a sensor/encoder. The microprocessor includes ROM and RAM memory circuits, a timer, and a clock, and it can activate a stepper motor to control the position of a detent pin. The microprocessor is also connected to a display, which has fields for hours, minutes and seconds, as well as for the days of the week, for a cursor for each day, and for a low-power indicator. System time, as well as opening times for the lock may be set and changed simply by turning the key according to predefined routines. A method for operating the lock includes sets of steps for each of several routines: setting real time, setting opening times for each selected day of the week, and specialty routines including adding an intermediate opening time, cancelling the opening time for selected days, adjusting the system time, for example to change to or from daylight savings time, and verifying the version of the time lock in use.Type: GrantFiled: August 23, 1994Date of Patent: January 14, 1997Assignees: La Gard, Ciposa Microtechniques SAInventors: Larry Cutter, Klaus W.

Patent number: 5142890Abstract: An electronic lock for a safe door is provided with a digital keypad entry device, a mechanical bolt works and associated handle for retracting the door bolts, and a spring biased rotary bolt which engages and precludes operation of the bolt works, such that upon entry of the predetermined code into the entry device, an electric signal causes a solenoid to energize and retract its armature from a blocking position relative the rotary bolt, further enabling the rotary bolt to rotate against its bias in response to mechanical manipulation of the handle by the user to retract the door bolts. Unauthorized operation of the safe handle causes the rotary bolt to be locked into a fixed position, preventing entry into the safe.Type: GrantFiled: July 31, 1990Date of Patent: September 1, 1992Assignee: La Gard, Inc.Inventors: Alan K. Uyeda, Klaus W. Gartner, John Herrmann, Peter J. Phillips

Patent number: 5136870Abstract: An electronic door lock is provided with a single control knob used for entering a predetermined combination through manipulation of the knob in a first arc of rotation, the code being entered by pushing the dial inwardly to bring a push pad into contact with individual ones of an arcuate array of electrical switches provided on a printed circuit board within the lock dead housing, the release of the door locking bolt being accomplished after entry of the predetermined code by further manipulation of the control knob through remaining portions of knob rotation which are unavailable until after entry of the predetermined code. A digitally operated code input pad assembly is also provided to enter such code and a second code to open a second lock mechanism associated with the door spring bolt giving two levels of security for the human passage door.Type: GrantFiled: February 12, 1990Date of Patent: August 11, 1992Assignee: Alan K.

Patent number: 5110009Abstract: A coin roll dispensing mechanism for use in dispensing coin rolls from a safe, the mechanism includes a coin roll dispenser for selectively distributing individual coin rolls, electrically operated solenoids to prevent operation of the dispenser and a first electrically operated combination entry device to disengage the solenoids. The safe door has a door handle, a plurality of bolts, a bolt works to manipulate the bolts, and electronic lock to restrict manipulation of the bolt works and a second electrically operated combination entry device to disengage the electronic lock. Upon entry of a first code sequence, the user can select a coin roll to be dispensed. To unlock the safe, a second code sequence is entered, which disables the electronic lock, allowing manual manipulation of the door handle.Type: GrantFiled: October 23, 1991Date of Patent: May 5, 1992Assignee: Alan K.

Patent number: 5054350Abstract: Apparatus for making a duplicate key when an original key is unavailable wherein the notches in the blade of the key correspond to predetermined coded depth and spacing information. An index card having indexes thereon corresponding to predetermined coded depth and spacing information is inserted into a housing and a key having a blank blade is inserted into a key holder where it is held in a series of predetermined positions relative to a key nipping tool and corresponding to the coded depth and spacing information on the index card. Key blank positioning is indicated by a pair of pointers having arcuate movement corresponding to the coded indicia on the index card.Type: GrantFiled: September 25, 1989Date of Patent: October 8, 1991Assignee: H.P.C., Inc.Inventors: Klaus W.
