Forced-entry-resistant sash lock
A forced-entry resistant sash lock includes a housing, a shaft pivotally mounted to the housing, a cam mounted on the shaft using an elongated opening permitting selective rotational and translational movements, and a separation member secured to the shaft. In the unlocked position, upon shaft rotation in a first direction a cam surface on the separation member engages a follower surface on the cam causing co-rotation of the cam into a non-forced entry-resistant locked position, and upon continued rotation the cam surface moves relative to the follower surface causing cam translation into a forced-entry-resistant locked position through movement of the shaft within the elongated opening, until an engagement surface of the separation member engages a contact surface of the cam, preventing forced reverse cam translation. The cam translation causes a cam stop surface to engage a housing stop surface preventing forced cam counter-rotation. |
