  • Patent number: 6045168
    Abstract: A vehicle door latch mechanism (10) having an improved double lock assembly (34). The present double lock assembly (34) is disposed between the latch handle assembly (30) and the latching assembly (26). In the un-double locked configuration, the double lock (34) allows motion transfer from the latch handle assembly (30) to the latching assembly (26) by extending the secondary intermittent member (36). In the double locked configuration, the double lock (34) retracts the secondary intermittent member (36) to prevent motion transfer between the latch handle assembly (30) and the latching assembly (26), preventing any unlatching of the door (12) even if the lock assembly (32) is in the unlocked configuration.

  • Patent number: 6042161
    Abstract: A flexible coupling is provided for a lock actuator and a latch assembly. The coupling is particularly useful for sliding glass doors and enables the actuator to be mounted to the door in an axially offset relationship with respect to the connecting member of the latch assembly. The coupling includes a male member that includes an outwardly protruding knuckle that is pivotally and frictionally received in the socket of a female member. The male member is connected to either the lock actuator or the latch assembly while the female connector is connected to the other of the lock actuator or the latch assembly. Rotation of the lock actuator results in rotation of both the male and female member thereby resulting in rotation of the connecting member of the latch assembly even though the actuator is disposed offset from the connecting member.

  • Patent number: 6032989
    Abstract: A locking ring includes two semi-annular ring portions with a U-shaped cross section. The locking ring serves to retain an electric meter in its meter socket in a manner which is well known. Both ends of each ring portion terminate in housings, each housing having an axial lock receiving aperture therethrough. When the ring halves are brought together to form a complete circle, the clockwise-most and counter-clockwise-most housings slide over each other until their lock receiving apertures are in axial alignment. A barrel lock can then be inserted into each of the two sets of aligned apertures, to secure the locking ring against opening. When a barrel lock is removed from either set of apertures, the ring can be opened at that location and removed from the meter.
