falling walls

Old Bed Frames.

Many years ago, (notice how many of my posts say that?) I was given something like 95 old bed frames from the defunct college here in town. I cut and welded them together making many things here, then years later some of the welds began popping apart because the metal they were made of was not quite your normal steel but maybe a steel/wrought iron mix?
Most of the welds have remained intact but one weld breaking at a certain place at the wrong time could cause some real problems...
Some of them were almost impossible to drill holes through too.

I knew I had these drawings somewhere, but here's a couple of views of how our the framework for our walls are made:

Neither drawing shows the safety cables, but I hope you can get the idea. By breaking each segment into 15 degrees, the end result puts the top portion directly above their heads and the scare factor is increased much more than if the wall just tips out at the top.

my best scare used a door hinged at the bottom screwed to the floor, When people walked in the chainsaw man kicks the door down as he comes into the room. We designed it so it was partitioned so no one was hit by the door. This was a great scare but killer on the actor (me) as the door was manually pulled up on a rope and pully system thousands of times a weekend. We later used it again in our new location but alas it only lasted our first hour as it was a thru put killer sending crazed people back into the haunt and backing up groups

How About

How about a Pneumatic piston activated by motion sensor or pressure pad,and then a switch when wall falls to activate something like a garage door type of mechanism with a stop switch to switch off the motor when the wall has been returned ? ( Like that of a Garage Door Switch )

the garage door and p[iston idea makes perfect sense. Thanks for all the insight. Have been busy with other things latley, but will be getting back to it soon.
