Electric door bump thingie

Working on a custom maglock project. I need something like a 12v solenoid to
"bump" a hidden door opened after the maglock releases. There's no visible
means of opening the door from outside the room. Just has to bump the door
opened enough so you can grab the door to open it.

Or..any other ideas?

Sure. The door unlock solenoid from a car would probably do the trick.
And it's 12 Volts too.

You could use the normally open/normally closed contacts on a relay to
handle both the maglock "unlock" and the door push solenoid functions
(same side of the relay).

"Thingie" is between "doo-hickey" and "thing-a-ma-jig" on the
complex-o-meter.

Another thought. Is the door closed mechanically (door closer)?
Sometimes you can adjust these to keep the door slightly open. This
would of course require the customer/end-user to push the door closed to
engage the mag lock on the "outside" of the door and a handle on the
inside to pull it closed. When the lock released, the door would "pop"
open enough to grab it (that's actually the simpler way to handle it).

Hinge the door with pins top and bottom 6 inches from one side. Push that
end in and the other end will pop out.

Why not just install a pull handle on the outside?

That's what I was thinking...a trunk release solenoid.
Yep..on the relay...I got it all figured out except to find a suitable
solenoid ... or another way to do it if anyone had a better idea

thanks
!

It's already hinged with 6 invisible hinges - i think they're called mortise
hinges.

It's a hidden door to a safe room, the part that you would see if you were a
burglar is just a huge mirror...no handles no hinges.

How about a #12 wood screw and a pair of vice grips?

Just a small coil spring between the door and the jamb - will hold it
slightly open normally, but once the maglock is engaged and the door
pulled shut, it'll stay shut.

Maybe not the fanciest solution, but by far the simplest, I think.

Ohhhhhhhh now it is making some sense. At first I thought you were working
on a handicap issue. It is much easier now.

Simple solution #1 Pick up some coil springs at the local hardware store.
Either drill holes to match diameter and epoxy or press fit into holes. The
holes would be in the jamb portion of the frame and would compress when the
door is shut and the mag is energized. When the mag is de-energized the
springs would then just push the door open. You could install the spring in
the door itself at the top on the strike side. Mount and small angle
bracket for it to push against. Simple?? Yes!!!!

Not as Simple solution #2 Go to a local auto parts dealer and pick up a
gas charged support rod. Like what is on lift gates or hoods. Here you
will have to find one that has the right dimensions to fit your door. When
fitted properly and the door is closed with the mag energized all is well.
When the mag is de-energized the gas piston will gently push the door open.

Please send all royalties to: Me

Good luck,

Les

that you would see if you were a burglar
is just a huge mirror...no handles no hinges.

Hmm. How about an auxiliary, permanent magnet (instead of an armature) and
a DC operated magnetic lock. When the main lock is released simultaneously
send power to the aux unit, pushing the door open. One advantage to such an
arrangement is it would require no moving parts other than a relay. This
would not be a substitute for the door lock -- just a separate unit to push
the unlocked door open far enough to grab it.

One other solution would be to mount a power operated door opener -- the
same as are used in stores to open the door. That eliminates needing to
remember to manually close the door each time.

Good ideas, but the door is very very heavy and I think your suggestions may
be a bit finicky.

Thanks.

We've been thinking on this and it may work and then again it may be
finicky. We'd have to find a spring loaded side mounted plunger which I
remember seeing somewhere...sometime, but can't seem to find one now (of
course).

So far it's;
springloaded plunger
solenoid actuated pusher dealybob.

I'd even though of dumping the maglock idea and going with a handicapped
door actuator...anyone know anything about these?

btw...this system will fail-secure


| Spring-loaded plunger? Mount on head jamb, push door shut, compressing
| spring, when mag-lock releases door opens an inch or two. Fail-safe to
| boot.

Something in there should suit your fancy.

Springs on the hinge side between the hinges to push the door to an open
position.

Still simple.
