This mission can simply be an engineering STEM lesson. Find out about levers and mechanisms – extra particulars under!

My oldest son designed the mechanism for the primary locking field, after which I constructed the field in order that it might look good. We make a great staff. He is an important engineer and comes up with mechanisms that I couldn’t create, however he does not do “cute” or making issues look inventive. I can deal with that half!

The way to construct a LEGO® Protected with a Key:

I’d advocate beginning with a 16 x 16 plate. It is a good dimension for constructing a drawer that is not large, however can maintain loads of cash or different objects.

Determine what dimension you need the drawer to be. Cowl an space that dimension with tiles in order that the drawer will be capable of slide simply. The tiles proven make a 12 x 12 sq..

You will want a wall of bricks in entrance of the drawer and in again of the drawer. Depart one facet fully open. On the opposite facet, you may have to construct a channel for the important thing.

(We’ll speak about that pin protruding in a minute.)

This is how the important thing works. I eliminated just a few extra bricks as a way to see every thing clearly. The thought is that the important thing slides into the channel. If you flip the important thing, the enamel match by openings within the wall and push the drawer open.

To make use of the important thing, you may slide it into the channel. Slide all of it the best way in till it hits the again of the protected.

Construct a 12 x 12 drawers. I used two 6 x 12 plates and hooked up them with a 4 x 8 plate. The drawer is 4 bricks excessive. Then there’s a row of tiles across the prime.

Then flip the important thing to the left. The enamel on the important thing ought to push the drawer out.

The drawer doesn’t come out far by itself. This picture reveals how far the drawer will come out. Then you need to use your fingers to drag it out the remainder of the best way.

You need to use a pin to maintain the drawer from sliding out when you do not need it to. Slide a pin right into a Technic brick and construct it into your protected. Then add a Technic brick on the drawer.

Ensure that the peak of the pin strains up with the peak of the outlet on the drawer!

When you get the mechanism working, place the drawer within the protected. Then construct up the perimeters in order that their peak comes precisely to the highest of the drawer.

If you’d like a coin slot, add a 1 x 4 tile to the highest of the body. Then add one other row of bricks.

End up the machine by inserting a 16 x 16 plate on prime.

Then construct some decoy keys, ha ha. The one within the center is the one which works.

This is a second strategy to construct a LEGO® protected.

It is a cool design as a result of it exhibit the usage of a lever. If you push the important thing ahead into the protected, it pushes on the underside finish of a lever, which pushes the highest finish of the lever (and the drawer) ahead.

We discovered this design on YouTube and constructed it based on the directions. I am going to embody the video under as a way to construct your personal! It is such a intelligent design.

Push the important thing into the slot on the underside of the protected.

And the drawer pops open!
