  • Patent number: 6739633
    Abstract: A fuel filler door actuator including a motor, a gear train coupled to the motor and to a latch arm, and a locking cam coupled to the gear train. The locking cam resists movement of the latch arm from an unlocked condition to a locked condition. A manual override cable is disclosed for manually moving the latch arm from the locked condition to an unlocked condition. A push—push mechanism is disclosed for allowing facile opening of a fuel filler door, and a quick connect/disconnect feature is disclosed for allowing facile assembly of the actuator to a fuel filler door housing.

  • Patent number: 4445684
    Abstract: A leg stretching machine comprises a seat fixed to one end of a shaft having a winch connected to slideably mounted spreader arms for splitting one's legs apart to stretch and develop leg muscles. The spreader arms are pivotally connected to a cylinder mounted on the shaft at the end opposite to the seat. The ends of the spreader arms not pivotally connected have pads. The padded ends of the spreader arms rest against the insides of the lower legs of the exerciser sitting in seat. The winch is used to pull the cylinder towards the seat. This causes the spreader arms to exert force against the insides of the exerciser's legs thereby spreading them. A ratchet device on the winch allows holding control at any leg split position. A hand grip is also mounted on the shaft between the seat and the spreader arm cylinder. This allows the exerciser to pull the upper body closer to the floor thereby simulating various martial arts positions.
