Rim type door lock with interchangeable bolt assemblies and adjustable backset plate assemblies

A lock assembly interchangeable for selectively assembling or producing an electronic Fail-Safe or Fail-Secure and or mechanically operated slam latch lock for mounting on the rim of a narrow stile or large stile door comprising:

• a) a housing having four sides, one side having a bolt opening and a closed top side having solenoid mounting holes, multiple door installation mounting holes, and a knob hole, and said housing defining an open area for receipt of a flat plate cover for Fail-Safe lock assemblies or adjustable settings backset plate assemblies for Fail-Secure and Mechanical lock assemblies;
• b) a solenoid having mounting holes disposed within said housing including an anvil fixably mounted within said solenoid assembly having mounting holes, an electrical lever switch, an electrical coil with a tubular central core hole having an anvil side and a plunge in side, said anvil having a central throughbore running along an axis of said solenoid and said anvil being fixably mounted at the anvil side within said solenoid coil core hole and with a first plunger also having a central throughbore running along the axis of said solenoid and said first plunger being movably mounted within said solenoid core hole, the said anvil side facing the said bolt opening side of said housing, the said mounting holes of the said solenoid matched up with some of said mounting holes of said housing;
• c) said first plunger having an outer plunger spring and a first crosspiece being fixably attached to an outer end of the said first plunger, said first plunger being movably mounted within said solenoid between locked and open position for Fail-Safe use;
• d) a first bolt assembly within said lock movable between locked and open position and having a first bolt, said assembly comprising a shaft extending from said bolt being removably and movably mounted within said lock with said bolt extending forward through said bolt opening of said housing, the extending shaft passing through said bolt opening of said housing, the extending shaft passing through said central throughbores of said plunger and said anvil, said extending shaft having a free end that contains a groove extending through the outer end of said first plunger to receive a mountable means to hold and control the movement of said first bolt, said first bolt being substantially ramp shaped to aid said bolt assembly to retract to slam latch lock when said lock is operated on a door and encounters a strike on a door frame while said solenoid is energized holding said lock in the locked position electronically with said anvil and said plunger in magnetic contact and said first crosspiece pressing on said electrical lever switch of said solenoid to reduce current flow to permit said solenoid to remain cool, said shaft having a wide portion and a narrow portion, said narrow portion having a second spring disposed thereon, said second spring on said shaft urging said bolt assembly outwardly to the locked position while said spring on said first plunger urges said first plunger inward to the open position so that said bolt assembly and said plunger may move in opposite directions along said axis from front to back of said solenoid Fail-Safe latch lock;
• e) said mountable means is for removably mounting said first bolt assembly from within said plunger and anvil at said free end of said shaft so that said bolt assembly can be pulled out and replaced or rotated to fit inswing and outswing applications on a door rim;
• f) a second bolt assembly for a Fail-Secure lock assembly being interchangeable with said first bolt assembly and having a second bolt, a clamp plate, a second plunger having a spring for urging said second bolt assembly to a locked position disposed thereon and space between said second bolt and said clamp plate for a removably mounted second crosspiece, said second bolt being substantially ramp shaped to cause the lock to latch lock when a door is swing slammed closed, means securing said second bolt and said clamp plate to said second plunger and being removably mounted with said second plunger within said solenoid and lock, after said solenoid being set into the said housing with only the said affixed anvil within said solenoid coil core hole, said mounting holes of said solenoid being set together with some of said mounting holes in said housing used for reversing said solenoid so that the lock can be changed from a Fail-Safe lock to a Fail-Secure lock, said solenoid being mounted in said housing with said plunge in side of said solenoid facing said bolt opening side of said housing for Fail-Secure use, said housing being provided with a knob and lever utilized with said knob hole in said housing;
• and
• g) said second bolt assembly being removably mounted within said solenoid and lock so that said second bolt assembly can be rotated to fit inswing and outswing applications on a door rim, said second bolt assembly entering the said lock housing through the said bolt opening of said housing lead by a front end of said second plunger, said second plunger entering said core hole of said solenoid from said plunge in side and said second plunger slidable within said core hole of said solenoid and said second bolt of said second bolt assembly being slidable within the bolt opening of said housing.
