  • Patent number: 5936500
    Abstract: An electrically operated actuator mechanism for remote locking and unlocking of a door. The moveable bolt is coupled to a solenoid armature for movement in a guide which is registered against the door in the closed position. The solenoid coil bobbin is stationary and the pole frame including a magnet, bolt guide and bolt are slidable thereon for locating the bolt guide against the door at installation. A spring biases the bolt into engagement with the door. Upon coil energization in one direction, the magnetic flux of the coil and magnet are sufficient to move the armature and retract the bolt unlocking the door. Upon de-energization of the solenoid coil the magnet holds the armature and bolt in the unlocked position. Upon subsequent re-energization of the coil in the opposite direction, the magnet flux is neutralized and the spring returns the armature and bolt to the locked position. The actuator is particularly suitable for automotive fuel filler access door locking/unlocking applications.

  • Patent number: 5664811
    Abstract: A release mechanism for use with fuel filler door latch systems that provides superior control of door movement during the entire service life of the motor vehicle. The biasing mechanism of the present invention includes a kick-out spring that acts directly against the striker bar. As such, the kick-out spring is not exposed to over-stressing and does not cause undue wear of the automobile body. The kick-out spring is a leaf spring having a first end that is secured to the housing, an intermediate section routed between posts extending outwardly from the housing, and a cantilevered second end that is oriented to be engaged and resiliently deflected by the striker bar when the fuel filler door is moved toward its closed position. In the closed position, the striker bar forcibly biases the second end of the kick-out spring to a deflected position.

  • Patent number: 4987968
    Abstract: A transmission shift interlock device which prevents a motor vehicle operator from shifting the automatic transmission shift lever out of the park or neutral position unless some action such as the brake pedal being depressed is taken. The device provides interlock capability by locking the transmission shift cable. An in-line solenoid is provided within the shifter cable having a movable armature which, when energized, forces locking balls or other engagement features into interlocking engagement with the cable core or rod member attached thereto. An alternate embodiment provides an adjustment link for accommodating vehicle tolerance variations and further provides means for having interlock capabilities at more than one shifter position.

  • Patent number: 4979384
    Abstract: An improved deck lid lock with remote release for motor vehicles. The deck lid lock employs a solenoid operated rotatable armature which acts directly on a leg of a rotatable latch plate which engages a lock bar. On energization of the solenoid, the armature is attracted to the solenoid causing it to disengage the latch plate so that the deck lid may be opened. When the deck lid is closed, the lock bar is engaged by the latch plate which is returned to its normal latched position in engagement with the armature. The deck lid lock further includes a rotatable key cam which acts on the armature to enable release of the deck lid through conventional external key actuation.

  • Patent number: 4971370
    Abstract: An improved deck lid lock with remote release for motor vehicles. The deck lid lock employs a solenoid operated axially movable armature which is directly coupled to a rotatable lever. The lever is normally biased to a latched position. The lever is lockingly engageable with a rotatable pawl which is normally biased to a latched position. The pawl engages a pair of rotatable, asymmetrically oriented striker cams which are normally biased to an unlatched position. The striker cams define a cavity for engaging a striker. Upon energization of the solenoid, the armature is attracted to the solenoid causing it to rotate the lever so as to disengage the pawl. The normal biasing of the striker cams overcome the biasing of the pawl to rotate the striker cams to the unlatched position thereby opening the deck lid. When the deck lid is closed, contact with the striker over-rotates the striker cams permitting the pawl to rotate to a latched position thereby lockingly engaging the lever.

  • Patent number: 4454491
    Abstract: A circuit breaker or switch utilizes the Curie point temperature characteristics of an amorphous ferromagnetic metal in cooperation with a magnet to make or interrupt an electrical circuit upon the amorphous material being heated to its Curie point temperature. The circuit breaker has a planar base member with a raised projection which supports a stationary contact member so that the movable contact member overhangs the stationary contact member. The movable contact member is provided with a number of layers of amorphous ferromagnetic material, disposed adjacent the stationary contact, bringing the movable contact member into electrical contact with the stationary contact member. Upon reaching its Curie point temperature, the amorphous ferromagnetic material will become paramagnetic or nonmagnetic material, so that the inherent resiliency of the movable contact material causes the electrical circuit to be made or broken.
