CYLINDER LOCK WITH INTERNAL SLIDER AND KEY THEREFORE

摘要

A lock and key combination includes a cylinder rotatably disposed within a shell and a sidebar within the cylinder and movable between a locked position preventing rotation of the cylinder and an unlocked position allowing rotation of the cylinder. A slider is mounted within the cylinder for movement between a first position blocking movement of sidebar from the locked position and a second position not blocking movement of said sidebar. A key has a blade configured to be inserted into a keyway of the cylinder and includes a slider-actuating element mounted within the blade for movement with respect to the blade. As the blade is inserted into the keyway, a cam element within the keyway moves the slider-actuating element to a position engaging the slider so that further movement of the key moves the slider from the first position to the second position.

1. A lock and key combination comprising:
a cylinder rotatably mounted within a shell and having a keyway formed therein; a sidebar mounted within said cylinder and configured for movement with respect to said cylinder between a locked position engaging said shell to prevent rotation of said cylinder with respect to said shell and an unlocked position disengaged from said shell so as to allow rotation of said cylinder with respect to said shell; a slider mounted within said cylinder and configured for movement within said cylinder between a first position blocking movement of said sidebar from the locked position to the unlocked position and a second position not blocking movement of said sidebar from the locked position to the unlocked position; a key having a blade configured to be inserted into said keyway, said blade including a first side and a second side, wherein said slider is mounted within said cylinder adjacent to a side of the keyway corresponding to the first side of the blade of a key inserted into the keyway; a slider-actuating element mounted within said blade for movement with respect to said blade between a first position projecting from the first side of said blade and a second position projecting from the second side of said blade; and a cam element within the keyway and configured to engage the slider-actuating element as said blade is inserted into the keyway and move the slider-actuating element to the first position whereby the slider-actuating element projects from the first side of said blade and engages said slider to move said slider from the first position blocking movement of said sidebar from the locked position to the unlocked position to the second position not blocking movement of said sidebar from the locked position to the unlocked position.
