Abstract
A solenoid operated locking mechanism uses a permanent magnet to secure a lockable rod to the solenoid locking mechanism. A solenoid operated plunger determines the location and movement of locking members that extend into a locking chamber, thus controlling the movement of the lockable rod past the locking members. Inserting the lockable rod into the locking mechanism forces the plunger against a spring toward a permanent magnet that holds the plunger in the locked position until an electrical pulse energizes the solenoid which reduces or cancels the permanent magnet's magnetic field and allows the lockable rod to be withdrawn from the locking chamber. The locking mechanism only requires energy to be applied to the solenoid to release the locking rod from the solenoid. The locking mechanism only requires energy to be applied to the solenoid to release the locking rod from the solenoid.
