Toggle Lock

Doing some research, with help from some of you guys, I keep seeing mention of the toggle locking system or toggle-joint locking system. As a novice, would someone be kind enough to explain what this is or where I would find information on this, maybe a diagram, pictures, etc.? Thanks.

The "knee action" parts are the toggle.

Print it out, enlarge it, cut it out, put it onto a cardboard backing and put a pin where the link is, then move it manually as you discuss it, or make several of them and hand them out.

or take out a real one and take it to class.

The most distinctive feature of these pistols is undoubtedly the toggle-lock mechanism, which holds the breech closed by locking in a manner not unlike the human knee, which can sustain a heavy weight when straight, but once bent is quite

easy to continue to bend. The toggle joint in its straight position resists the rearward force of the detonating cartridge, then "buckles" after enough time has passed.

When a round is fired the entire breech, barrel and toggle move straight rearward (on rails) until the toggle begins to ride up on a pair of cams that "breaks" the toggle (makes it bend at the joint). Once the toggle joint is no longer straight, it bends freely, allowing the bolt to come rearward, and the striker to be cocked. The spent

cartridge is extracted by a combination extractor/loaded chamber indicator on the top of the toggle, is ejected as the toggle nears the end of its rearward travel, and a

new round is stripped from the magazine and chambered as the toggle is driven back to the straight position by a spring.

Some of the classic Luger references can be pretty pricey, escpecially those that are out of print! regards, John Toggle Lock Thread - Click here http://boards.rennlist.com/upload/Toggle-lock.jpg
