Abstract
An antiprying member is secured onto a metal frame adjacent a protective flap member secured onto a security door that is hingedly mounted onto the metal frame. The antiprying member extends along the free end of the flap member and has a thickness at least the same as that of the flap member and is spaced from the flap member no greater than the thickness of the flap member to prevent a prying member from bending the flap member away from the metal frame or to pry open the security door. A pin having an annular notch is secured to the flap member and extends through a hole in the door frame to prevent the door frame from being pried or twisted away from the door.
Claims9
A security door for a building, comprising:
- a metal frame for mounting onto the building and extending along the sides and upper end of a doorway;
- a security door hingedly mounted onto the metal frame and movable between closed and open positions;
- a protective flap member secured onto the security door overlying the latch and lock members thereof and engaging a section of the metal frame when the door is in a closed position to protect the latch and lock members;
- and
- an antiprying member secured onto the section of said metal frame and extending along the free end of said flap member, said antiprying member having a thickness at least the same as that of said flap member and being spaced from the flap member no greater than the thickness of said flap member.
A security door for a building, comprising:
- a metal frame for mounting onto the building and extending along the sides and upper end of a doorway;
- a security door hingedly mounted onto the metal frame and movable between closed and open positions;
- a protective flap member secured onto the security door overlying the latch and lock members thereof and engaging a section of the metal frame when the door is in a closed position to protect the latch and lock members;
- and
- a pin member having notch means secured onto said protective flap member and disposed in a hole in said metal frame when the flap member engages the metal frame so that upon a prying member being disposed between the metal frame and the door and prying forces being applied thereto, the surface of the hole is forced into the notch means thereby preventing the metal frame being pried or twisted away from the door.
For use in a doorway closure of the type that includes a frame, a door hinged to the frame to swing outwardly for opening thereof, and latch and lock mechanisms on the frame and door for securing the door in a closed position in the frame, the latch and lock mechanisms having plungers for position in openings in the door frame, a protective flap member secured onto the door overlying the latch and lock mechanisms and engaging a section of the frame when the door is in the closed position to protect the latch and lock mechanisms;
- an antiprying member secured onto the section of the frame adjacent an edge of the protective flap member, said antiprying member extending along at least the entire length of the protective flap member and having a thickness at last the same as that of the protective flap member and being spaced from the edge of the protective flap member no greater than the thickness of the protective flap member.
