Claim Text:
1. A solenoid operated coupling for connecting a solenoid body to a lockable head of a lockable rod comprising: a solenoid body comprising a solenoid coil, a front and a rear, a locking chamber extending from the front of the solenoid body and disposed within the solenoid body for receiving in locking engagement the lockable head of the lockable rod, a solenoid operated plunger slidably mounted in the locking chamber, at least one locking member mounted in the solenoid and adapted for movement into and out of the locking chamber in response to movement of the plunger, the solenoid operated plunger allowing movement of the locking member into the locking chamber when the plunger is in a first unlocked position, the solenoid operated plunger restricting the lockable head from moving past the locking member when the lockable head is in the locking chamber when the plunger is in a second locked position, a recess in the solenoid operated plunger for receiving the locking member when the plunger is in the first unlocked position, a permanent magnet mounted at the rear of the solenoid body, a spring mounted between the permanent magnet and the plunger for providing a force against the plunger for pushing the plunger toward the front of the solenoid body, the locking member engaging the lockable head to retain the lockable head in the locking chamber when the plunger is in the second locked position, the locking member being pushed out of the locking chamber by the movement of the lockable head to release the lockable head from the locking chamber when the plunger is moved to the first unlocked position, the permanent magnet holding the plunger in locked engagement when the plunger is in the second locked position and releasing the plunger when the solenoid coil is energized.
