ABSTRACT:
A check rail lock securable to the top rail of one window sash of a double hung window, including a housing, a cam pivotable about a first axis within the housing between an open position and a locking position, a pin extending from the bottom of the cam, and a guard member disposed substantially beneath the cam and pivotable about a second axis within the housing, the guard member having a slot receiving the pin for moving between a guarding position and a retracted position responsive to pivoting of the cam between the locking position and the open position. The cam in the locking position includes a portion extending from the housing and adapted to cooperate with a keeper secured to the other window sash to lock the one window sash in a closed position relative to the other window sash. The guard member extends from the housing to substantially overlap with the cam extending portion in the guarding position and the guard member is substantially entirely retracted into the housing in the retracted position. The guard member slot is oriented whereby a force biasing the guard member from the guarding position toward the retracted position biases the pin generally toward the first axis or overcenter to bias the cam toward the locking position.
