Abstract

A security guard for mounting to a frame of a window opening in a building includes an elongated channel bar having a plurality of mounting pins secured to one end thereof and a key actuated lock visible and operable only from the interior of the building mounted within the confined flanged area of the bar at the opposite end thereof, the mounting pins and the retractable dead bolt of the lock cooperative with adjacent window frame structure to securely but releasably retain the channel bar in position next to the window on the interior side thereof. The spaced pins prohibit the bar from being rotated and an additional lock cover member mounted to the bar substantially coextensive of the lock protects the lock from external tampering. Suitable grill work or the like may be mounted to and supported by the channel bar.
