20090056392 | DOOR LOCK ASSEMBLY - A lock assembly for use with a latch movable from an extended position to a retracted position, and the lock assembly includes an interior assembly and an exterior assembly. The interior assembly includes an interior handle manually movable to retract the latch and a locking member manually operable such that the locking member is movable from an unlocked position to a locked position. The exterior assembly includes an exterior handle manually operable to retract the latch when the locking member is in the unlocked position and inoperable to retract the latch when the locking member is in the locked position. The exterior assembly further includes a biasing member that biases the locking member toward the unlocked position. When the locking member is in the locked position, movement of the interior handle to retract the latch causes the biasing member to move the locking member to the unlocked position. | 03-05-2009 |
20090071300 | Digital Beam Torque Wrench - A torque wrench includes a main beam having a distal end and a proximal end, a drive element disposed at the distal end of the main beam, a stationary beam having a distal end fixedly secured to the main beam at a first location on the main beam, and having a proximal end, and a displacement sensor assembly disposed at a second location associated with the main beam and with the stationary beam to detect an amount of displacement of the main beam relative to the stationary beam. The displacement sensor assembly includes an actuating element to produce a radiation signal and rigidly secured to one of the main beam or the stationary beam and an actuable element responsive to the radiation signal and rigidly secured to the other one of the main beam or the stationary beam. | 03-19-2009 |
20090260491 | MULTI-PINION GEAR DIGITAL BEAM TORQUE WRENCH - A digital torque wrench includes a position sensor assembly which measures the movement of a load beam with respect to an indicator beam to determine the torque being applied to a working element by the torque wrench. The position sensor assembly includes a first position sensor portion having multiple rotatable pinion gears coupled to a potentiometer, and includes a second position sensor portion having a rack gear that engages one of the pinion gears of the first position sensor portion. The first and second position sensor portions are attached to different ones of the load beam and the indicator beam so that at least one of the pinion gears rotates along the rack gear in response to force (torque) being applied through the load beam to the working element. Rotation of the pinion gears causes rotation of a potentiometer element, which produces a signal indicative of the relative displacement of the load beam with respect to the indicator beam. This displacement is then converted to a torque measurement and is displayed to a user via a display. The use of multiple pinion gears enables a high degree of resolution with respect to the torque measurements, while reducing the width profile of the torque wrench. | 10-22-2009 |
20110132158 | Digital Beam Torque Wrench with an Electronic Sensor - A torque wrench includes a main beam having a distal end and a proximal end, a drive element disposed at the distal end of the main beam, a stationary beam having a distal end fixedly secured to the main beam at a first location on the main beam, and having a proximal end, and a displacement sensor assembly disposed at a second location associated with the main beam and with the stationary beam to detect an amount of displacement of the main beam relative to the stationary beam. The displacement sensor assembly includes an actuating element secured to one of the main beam or the stationary beam and a sensor rigidly secured to the other one of the main beam or the stationary beam and responsive to the actuating element. An electronic component is configured to generate a torque measurement based on the generated electrical signal, and store at least one of the generated electrical signal and the torque measurement for a several positions of the main beam relative to the stationary beam. | 06-09-2011 |
