  • Patent number: 8096570
    Abstract: A cable actuator comprises a housing, a handle, and a locking pin. The handle is pivotally connected to the housing and is moveable between a released position and a locked position. The handle has a slot that terminates in a locking detent. The locking pin has a first end configured to pass through the slot and a second end configured to engage the locking detent. The locking pin is biased toward engagement with the locking detent such that when the lever is pivoted to the locked position, the locking detent aligns with the locking pin permitting the second end to engage the locking detent.
