YES!!! A Scooby Doo padlock from Sonic (a fast food restaurant here in the United States). Picked up two of them today... One for my son's lock collection and one for my collection.
This is a mid-sized lock.
And the back of the lock/ reverse side of the key.
The writing on the back side of the lock says "Sonic" "Scooby-Doo" "Mystery of the ghost tot". Then it gives trademark information, but surprisingly, no patent infor. Maybe Squelchtone can dig up the patent info for us.
Please excuse the pictures not facing the correct direction. Doing this on my phone at work while it is slow.
The lock opens smoothly and easily with the key - sure sign of a quality made work of art. And Art can be proud of himself for this work.
With the shackle open, you can see the locking dog.
Figured out a way to pick this lock! It takes a little practice. (What doesn't?). Put a pick into the keyway like this...
Now tip the handle of your pick to the left, using the face of the lock body for light leverage. This moves the tip of your pick to the right, bringing it into contact with the bottom of the lever. Push it just a little further aaannnnd... OPEN!
The securing screws are on the back. While they should require a triangular tool, a flat tool of the correct width will remove and reinstall the screws with no difficulty.
With the rear half of the lock body removed, you can see both of the internal parts.
Here you have the lever/locking dog and how it interfaces with the shackle while in the locked position. More on that in a bit.
Here are the same parts in the unlocked position.
The spring wraps around the lever, but showing the location in this picture with the lever removed for clarity.
Here the spring is installed on the lever facing the same way as when installed in the lock body.
And this view, from the reverse side, shows how the spring is installed into the lever prior the lever's installation.
This is that same spring.
The lever and spring correctly orientated.
All the parts installed except for the rear cover. The key is installed, and can be seen inside the keyway. Note the precision fit of the shackle to the lever/locking dog. That part touching the tip of the shackle toe pulls the locking dog into place as the shackle is fully seated.
Here the key bitting is acting on the lever, both moving the locking dog out if the way and pushing the shackle up. Simply marvelous engineering!
Open!
Thank you for joining me on this journey through one of the seven wonders of the lock world!
