ABSTRACT:
An improved security apparatus including a security grill having an extending left section and right section. The left section includes a left vertical support member, a plurality of tubular lateral support members extending rightwardly therefrom, and a plurality of vertical bars attached to and supported by the lateral support members. The right section comprises a right vertical support member, a plurality of tubular lateral support members extending leftwardly therefrom, and a plurality of vertical bars attached to and supported by the lateral support members. A plurality of intermediate extension members are each inserted into a corresponding pair of the left and right tubular lateral support members and are slidable therein to allow extension of said left security grill section with respect to the right section. The security apparatus includes a left angle bracket for securing one side of the security grill to a door or window frame, and a right angle bracket for securing another side of the security grill to an opposing side of said door or window frame. This way, the security apparatus may be attached exteriorly to a door or window frame to prevent forcible entry. In addition, the right grill section may be attached to the right angle bracket by a plurality of hinges to allow outward pivoting and to provide authorized access to the dwelling. Moreover, a number of hitch and mounting bracket combinations may be welded to the left angle bracket, and the left grill section may include a corresponding number of padlock enclosures welded to the face thereof, such that when the security grill is closed, the hitches protrude into padlock enclosures to allow locking with a conventional padlock. The padlock enclosure obscures access to the padlocks, thereby maximizing security.
