I woke up with this idea this morning and thought I?d throw some fresh meat into the lion den and see if I can?t start a really big cat fight. I hope I do.
The idea is to use a 12v Solenoid Operated Dead Bolt lock. It would be installed in mid-fuse decks. The bolt will point up and ultimately penetrate into the base of the door. The bolt operates when 12v is applied to the solenoid.
With a very tiny bit of wiring logic, the 12v can be routed through a micro-switch. That switch is used to detect when the interior (or exterior) handle has rotated X degrees (from fully open) toward the closed position. I?ll use 20 degrees for example.
- Get in and pull the doors down.
- Rotate the door handle to close the main door pins.
- From 0 degrees to 20 degrees the bolt is retracted.
- At 20 degrees the bolt engages to secure the bottom of the door (before the main pins have even started through the Nylon or Aluminum blocks).
- The bolt stays engaged until the handle is rotated back and the switch opens at 20 degrees. By having the bolt engage before the pins enter the door frame, it protects against those who are concerned with bumping the handle accidently.
A couple of fail-safe modes and emergency points.
- Should you need rescued from someone on the ground, it can be operated with the regular exterior door latch. They just twist the door latch and the micro-switch disengages the b
- Should you have a 12v power failure, the bolt will retract when the power is lost.
- Should you have an accident that rips the wire from the solenoid, the bolt will retract.
I can?t think of a failure mode that would cause a problem assuming you use a bolt that extends with 12v and retracts with 0v ? not the opposite.
One of my concerns were damaging the door by extending the bolt without having the door in the correct position. Meaning the bolt would miss it?s hole and it would push up and damage the bottom of the door.
After a little research, I found this lock has a safety circuit in it. The force of the bolt deployment is really low and if the bolt can?t extend into a recess, the 12v is removed. Saving the switch and any damage that could occur. Keep in mind it?s designed to deploy into a female recess and then the bolt is designed to operate in shear. The bolt isn?t designed to punch holes in wooden door frames ? or our RV-10 doors.
Okay, now that I?ve shaken this fresh chicken in front of ALL the lions, have at it. I?ve got a Houston RV builders group lunch to go to?.
