Locks_Come_In_All_Shapes_And_Sizes

Locks Come In All Shapes And Sizes Locks come in all shapes and sizes, with many creative design variations. You can get a clear idea of the lock by examining one simple, representative lock. Most locks are based on fairly similar concepts. Think about the normal dead-bolt lock you might find on a front door. In this sort of lock, a movable bolt or latch is embedded in the door so it can be extended out the side. This bolt is lined up with a notch in the frame. When you turn the lock, the bolt extends into the notch in the frame, so the door can't move. When you retract the bolt, the door moves freely. The lock's only job is to make it simple for someone with a key to move the bolt but difficult for someone without a key to move it. This is put to work in a cylinder lock. The most common lock design is the cylinder lock. In the cylinder lock, the key turns a cylinder or plug which turns an attached cam. When the plug is turned one way, the cam pulls in on the bolt and the door can open.
