  • Patent number: 6457752
    Abstract: A locking window. The window includes a window frame including a window sash which is selectively movable between a first closed position and a second open position. A window latch is adapted to be attached to the window and 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 a sweep latch, which is preferably offset, and a non-compressible pivot fastener for attaching the window latch to the window. The offset arrangement provides sufficient space for substantially unequal length actuator and locking arms to provide a mechanical advantage when the window latch is operated. The pivot fastener includes a support bushing and a fastener extending through the support bushing for attaching the offset sweep latch to the window.
