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.
Claims3
A window locking mechanism comprising in combination:
- bracket means having a flanged portion attachable to a window and having a supporting portion protruding over a window frame, when said flanged portion is attached to a window, said supporting portion having one angled side, and a supporting pin attached thereto;
- at least one disc shaped locking member rotably supported in said supporting portion on said supporting pin of said bracket means and being linearly shiftable therein, whereby said locking disc member will wedge between said angled member of said supporting portion of said bracket means and a window frame when said flanged portion is attached to a window having an opening force applied thereagainst;
- said locking member having a large center opening, larger than said supporting pin to thereby allow said disc to rotate on said supporting pin and to be lifted linearly thereon;
- and said bracket means supporting portion having an arcuate portion formed therein with said locking member protruding thereinto so that an operator's finger can lift the locking member for disengaging the window locking mechanism.
