Claims
- 1. Door security hardware for an exterior entry door mounted in a door opening having door jambs secured to a wall structure, said hardware comprising: a plate having a length greater than the thickness of a door and adapted to be mounted on a door jamb such that a first part of said plate extends beyond the outside surface of the door and a second part of said plate extends inwardly therefrom adjacent the edge of a door mounted in the door opening, said second part of said plate being formed with an aperture through which a door mounted article of hardware can project, and said first part of said plate being formed by folding a flat portion of said plate into an inner segment and an outer parallel segment spaced from said inner segment, said segments being connected to each other at a point remote from the outside surface of a door but separated spaced apart at the point adjacent the outside surface of a door, said first part of said plate being provided with aligned buck pin apertures in said two segments forming said first part of said plate; a buck pin insertable through said aligned buck pin apertures and into the wall structure, said buck pin being provided with a head portion that abuts said outer segment of said first part of said plate and a grooved portion spaced from said head portion and adapted to align with the space between said two segments of said first part of said plate when said buck pin is inserted through said buck pin apertures with the head portion thereof abutting said outer segment of said first part of said plate; and a retaining member formed with an open ended slot adapted to be placed in the space between said segments of said first part of said plate with said slot engaging said groove in said buck pin to prevent removal of said buck pin.
- 2. Door security hardware according to claim 1 wherein said plate is provided with screwholes whereby said plate may be secured to a door jamb by screws.
- 3. Door security hardware according to claim 2 wherein said screwholes are provided in said second part of said plate whereby screws securing said plate to a door jamb will be covered by a closed door.
- 4. Door security hardware according to claim 2 wherein said screwholes are provided in the inner segment of said first part of said plate and clearance holes are provided in the outer segment of said first part of said plate in alignment with said screwholes, and wherein said retaining member blocks access to screws securing said plate to a door jamb.
- 5. Door security hardware according to claim 1 wherein said outer segment of said first part of said plate is provided with screwholes, and said security plate is provided with threaded screwholes whereby said retaining member may be fastened in place to avoid its inadvertent removal.
- 6. Door security hardware according to claim 1 wherein said first and said second parts of said plate are separate and wherein said second part of said plate is provided with an extension portion that extends into the space between the two segments of said first part of said plate, said extension portion being provided with an elongated slot that aligns with the buck pin apertures provided in said first part of said plate so that said first part of said plate may be adjustably located relative to said second part of said plate.
- 7. Door security hardware according to claim 6 wherein said second part of said plate is provided with screwholes for securing said first and second parts of said plate to a door jamb, and wherein the inner and outer segments of said first part of said plate are provided with elongated slots aligned with said screwholes.
FIELD OF THE INVENTION
This invention is a continuation-in-part of application Ser. No. 024,301 filed Mar. 10, 1987, now U.S. Pat. No. 4,771,506.
This invention relates to hardware for doors, and more particularly to hardware for exterior entry doors that improves the security offered by such doors by minimizing the likelihood of the door hinges or strike being ripped from the door frame when a force is applied against the outside surface of the door.
My earlier patents, U.S. Pat. Nos. 4,547,009 and 4,656,691, disclose door hardware such as strikes and hinges that are securely anchored in the wall structure surrounding the door frame and thus resist being ripped from the door frame when a force is applied to the outside surface of the door, either at the lock or hinge edge of the door. The hardware is mounted on the door frame and it includes a segment that extends beyond the outside surface of the door and an integral buck pin that projects inwardly from the segment through the door frame and into the underlying wall structure. Thus, if the hardware is a strike, it will be anchored by the buck pin a substantial distance from the inside edge of the door frame where the ordinary strike is secured and susceptible to being ripped from the frame by a force applied to the door, and through the lock bolt to the strike. In a similar way, the jamb leaf of a hinge includes a segment that extends beyond the outside surface of the door and includes a buck pin that projects into the underlying wall structure. Thus, there is less likelihood than with an ordinary hinge, of the jamb leaf being ripped from the door frame by a force applied against the door at its hinge side.
It is an object of the invention to provide improved door hardware that enhances the security offered by an entry door.
It is another object of the invention to provide security hardware that is simple and inexpensive to manufacture.
It is still another object of the invention to provide adjustable door hardware that can be accommodated to door frames of varying depth.
In carrying out the invention, a strike or security device includes a door frame mounted element that is formed from a flat piece of steel that is bent into a J-shape with a pair of aligned buck pin apertures provided in the overlapping spaced apart portion of the element. A separate buck pin having a head portion and an annular groove formed therein is inserted through the apertures and into the wall structure beyond the door frame so that the annular groove is positioned in the space between the overlapping portion of the J-shaped element. A retaining plate slipped into the space between the overlapping portion of the J-shaped element engages the annular groove in the buck pin and prevents its removal. The J-shaped element is further provided with an aperture through which the bolt of a door mounted lock or a door mounted plate may extend. The J-shaped element may comprise two parts, a U-shaped channel member and a flat plate that adjustably overlaps the channel member so that the length of the element may be varied.
Features and advantages of the invention may be gained from the foregoing and from the description of a preferred embodiment of the invention which follows.
