A window guard installation in combination with a building and a building window, comprising:
- a window guard framework adapted to be positioned against an exterior of said building adjacent said window so as to extend over said window, to be held in place at least in part by a cam-latch system, said cam-latch system including:
- an elongated cam-latch element extending through a wall of said building to have an end protruding through said exterior thereof adjacent said window, said cam-latch element secured against axial movement but able to be manually rotated;
- said protruding end of said cam-latch element inserted into an opening in an elongated hollow shielding member extending transversely to said cam-latch element and forming a part of said window guard framework when said window guard framework is position over said window;
- a camming engagement portion and a latching portion on said protruding end of said cam-latch element;
- a latching member slidable within said hollow member, a spring urging said latching member towards said cam-latch element protruding end, said latching member having a portion aligned with said camming engagement portion so as to be able to be moved by said spring into latching engagement with said latching portion when said cam-latch element is rotated to a position whereat said camming engagement portion is facing said latching member portion, said latching member latched to said cam-latch element protruding end by engagement with said latching portion when said window guard framework is pushed onto said cam-latch element protruding end in being positioned over said window, said latching member latched to said cam-latch element with said latching portion thereof in engagement with said camming engagement latching portion, and said latching member pushed to be slid back against the force of said spring by said camming engagement portion upon rotation of said cam-latch element forcing said latching member portion out of engagement with said cam-latch element latching portion to release said window guard framework;
- a fixed latching post mounted to said building exterior at a location spaced transversely from said elongated cam-latch element, and having an end protruding into another opening in said hollow member when said window guard framework is positioned over said window, said latching post having a latching engagement portion on one side facing away from said cam-latch element and aligned with another portion of said latching member, said latching member extending transversely from said cam-latch element over to said fixed latching element to be positioned to receive said another portion thereof to be latched thereto when said first mentioned portion thereof is in engagement with said latching engagement portion on said cam-latching element protruding end, and both latching member portions simultaneously forced out of engagement with said cam-latching element latching engagement portion and said latching engagement portion on said latching post against the force of said spring by said camming engagement portion when said cam-latch element is rotated.
