SECURITY LATCH FOR A SWING BAR DOOR GUARD
The security latch for a swing bar door guard includes a post, a cross member connected to one end of the post, and a plate connected to a second, opposing end of the post. The plate can be installed adjacent to or formed with the rigid arm component of a swing bar door guard assembly to prevent the release of the swing bar from its retaining rod when the door is slightly ajar. The post and narrower dimension of the cross member can pass between the two swing bar arms. When the post and cross member are turned ninety degrees the cross member extends across the swing bar arms to prevent any substantial movement thereof. The post is frictionally mounted in the plate to hold its orientation when set. The plate and post are provided with stops to limit post and cross member rotation to no more than ninety degrees.
