US 7,063,361 B1 · Locking window

Abstract

A locking window having a window frame and a window latch for use with the window is disclosed. The window latch, which is adapted to be attached to the window using a distinct fastener, is selectively movable between a first open position and a second locked position to secure the window sash in the closed position. The window latch includes an actuator arm, a locking arm, a non-compressible pivot and a housing. A pivot location is situated at the union of the actuator arm and the locking arm. The pivot location permits the actuator arm and the locking arm to be selectively movable between a first closed position and a second open position. The housing may include a securing feature for maintaining the housing substantially set relative to the window while at the same time permitting the actuator arm and the locking arm to be selectively movable between a first closed position and a second open position.
