ABSTRACT:
A window or door guard made of one piece of protective material which conceals hinging and locking components from view and shields them from forcible attack. The guard may be unlocked with a key from the outside, or without a key only from the inside thereof, after which the guard may be easily opened to allow for an emergency escape. The guard may also be removed from its mounting and subsequently remounted, both without a key or tool. No springs, flexible cables, or parts inaccessible to inspection, cleaning, lubrication, or replacement are utilized.
