ABSTRACT:
A window locking mechanism includes a flanged bracket in which the flange is attached to the window so that the remainder of the bracket protrudes over the window frame. The locking bracket is in a shape to support a disc shaped locking member, loosely supported on a center pin and adapted to wedge between an angled side of the support bracket in the window frame at all times except when the disc is lifted to prevent wedging.
