Patent number: 8006526Abstract: A steering shaft lock actuator including at least one motor having an output shaft; a drive train coupled to the output shaft, a locking pawl coupled to the drive train; and a housing for at least partially enclosing the motor, the drive train, the locking pawl and the locking pin. The drive train may be configured to linearly urge the locking pawl and a locking pin between a locked position wherein the locking pawl and the locking pin extend at least partially out of the housing and unlocked position wherein the locking pawl and the locking pin are retracted toward the housing relative to the locked position. The locking pawl may be positioned to prevent rotational movement of the steering shaft when in the locked position. The locking pin may be positioned to lock the actuator to a steering shaft interface when in the locked position.Type: GrantFiled: April 27, 2007Date of Patent: August 30, 2011Assignee: Stoneridge Control Devices, Inc.Inventors: William H. Fort, Knight Ko

Patent number: 7464627Abstract: An actuator and door latch system incorporating the same. The actuator moves a door latch between locked and unlocked positions with rapidity using a gear train directly coupled to an actuator motor or energy stored in an energy storage element such as a spring.Type: GrantFiled: October 27, 2006Date of Patent: December 16, 2008Assignee: Stoneridge Control Devices, Inc.Inventors: Knight Ko, Brian Ganter, Thomas P Schregardus, Eric Beishline, William H. Fort

Patent number: 7213482Abstract: An electro-mechanical actuator is provided that minimizes back drive effort by de-coupling the internal drive train of the actuator from the actuator output using a clutch. The clutch facilitates transfer of power to an output gear stage when the actuator motor is energized, but disengages the output gear stage when the actuator motor is de-energized. When the actuator output is manually operated, the clutch disengages the output gear stage, thereby reducing the number of gears that must be back driven by the manual actuation.Type: GrantFiled: March 7, 2003Date of Patent: May 8, 2007Assignee: Stoneridge Control Devices, Inc.Inventors: Henry Minasian, William H. Fort

Patent number: 7134672Abstract: A failsafe actuator is provided for returning an actuator driven element to a failsafe position in case of a failure condition. The actuator includes a drive assembly for driving a plunger from a first plunger position to a second plunger position. The actuator additionally includes a stored energy element for driving the plunger from the second plunger position to the first plunger position on the occurrence of the failure condition, wherein the actuator driven element is responsive to the plunger such that the actuator drive element is driven to the failsafe position when the plunger is driven to the first position.Type: GrantFiled: July 23, 2003Date of Patent: November 14, 2006Assignee: Stoneridge Control Devices, Inc.Inventors: Eric Beishline, William H. Fort, Henry Minasian, Brian Ganter, Yuly Yanishevsky, Michael Johnson

Patent number: 6994357Abstract: A failsafe actuator for returning an actuator driven element to a failsafe position in case of a failure condition is provided. The failsafe actuator may include mechanical or electrical means to provide a failsafe function. Such a failsafe actuator may be used in a stabilizer bar system of a vehicle to ensure that at least one stabilizer bar is returned to a failsafe or engaged condition should a failure condition occur when the stabilizer bar is disengaged. Various failure conditions can include loss of electrical power to the actuator or some internal actuator failures.Type: GrantFiled: February 3, 2004Date of Patent: February 7, 2006Assignee: Stonebridge Control Devices, Inc.Inventors: Joe Heller, William H. Fort

Patent number: 5788008Abstract: A system for selecting either 2-wheel or 4-wheel drive in a vehicle which includes an actuator mounted on the differential housing of the vehicle drive system for engaging and disengaging the externally splined ends of opposing shafts in response to a signal switched from a power source in the vehicle cab. The actuator converts the rotary output of a DC motor to linear output of a carrier-mounted lead screw and drive nut which is transferred to a plunger which moves an internally splined ring between the opposing splined shaft ends.Type: GrantFiled: July 12, 1996Date of Patent: August 4, 1998Assignee: Joseph Pollak CorporationInventors: William H.
