Safe and secure door plate

Abstract

A door plate provides better safety and security. The plate cannot be kicked in or provide access to a door to be picked. The door plate, in conjunction with a doorjamb, makes one strong unit. The door plate wraps the vulnerable area of the doorjamb with its steel property thus becomes more impervious to splitting the edge of the doorjamb or any part of the protected area of the wrapping. A unique connection in the door plate provides further structural strength and avoids safety hazards when opening and entering a door.

DETAILED DESCRIPTION

(14) FIG. 1 shows a jamb and safety plate assembly 100. The assembly comprises an ordinary doorjamb 2 including a step 2a. FIG. 1 shows the assembly 100 without any exterior brick molding or the interior trim casing. FIGS. 1 and 2 show a safety plate 1 fixed to the doorjamb 2 and two strike plates 3, 4 of a lock unit and deadbolt unit not shown. Adjacent to the step 2a, a weather strip 5 runs along the boarder of the doorjamb and a portion of a weather strip 5a is affixed to over the safety plate 1 as shown in FIGS. 2 and 3.

(15) FIGS. 4-6 show the details of the safety plate 1. The safety plate 1 is comprised of a first web 1a and a second web 1c with a reinforcement hem 1h shown in FIG. 6. The first web 1a and the second web 1c are offset and parallel to each other. The reinforcement hem 1h is comprised of a first lip 1f extending perpendicular to the first flange 1a and bending to a second lip 1g that perpendicularly intersects the second web 1c. As shown in FIG. 5, the second web 1c includes at least one opening 1k. In the example of FIG. 5, the second web 1c includes two openings 1k where two strike plates 3, 4 fit and can be fixed to the doorjamb 2. The second web 1c includes at least one fastening hole 1j. Although, it is envisioned that at least one fastening hole 1j be on the second web 1c, more than one fastening hole can be located anywhere in the safety plate 1 to fasten the safety plate 1 to the doorjamb 2.

(16) As shown in FIGS. 4 and 6, the first web 1a and the second web 1c respectively includes at least one wrapping flange comprising a first wrapping flange 1d and a second wrapping flange 1e. The first wrapping flange 1d extends opposite to the first lip 1f and the second wrapping flange 1e extends opposite to the second lip 1g. Both wrapping flanges 1d, 1 e extend parallel and in the same direction to each other.

(17) FIGS. 7-9 show a second embodiment of the safety plate 10. Some features are the same as the first embodiment of the safety plate 1 shown in FIGS. 4-6. The safety plate 10 includes a first web 10a and a second web 1c. The first web 10a and the second web 1c are offset and parallel to each other. A reinforcement web comprised of a first lip 10f extending at an angle to the first flange 10a and connecting to a second lip 10g that perpendicularly intersects the second web 1c. As shown in FIG. 8, the second web 1c includes at least one opening 1k. In the example of FIG. 8, the second web 1c includes two openings 1k where two strike plates 3, 4 can fit and be fixed to the doorjamb 2. The second web 1c includes at least one fastening hole 1j. The first lip 10f is welded to the first web and the second lip 10g.

(18) As shown in FIGS. 7 and 9, the first web 10a and the second web 1c respectively includes at least one wrapping flange comprising a first wrapping flange 1d and a second wrapping flange 1e. The first wrapping flange 1d and the second wrapping flange 1e extend opposite to the second lip 10g. Both wrapping flanges 1d, 1e extend parallel and in the same direction to each other.

(19) FIGS. 10-13 shows a third embodiment of the safety door plate 20. This door plate is 20 is composed two pieces joined together forming a hem there between. Similar features as those door plates 1, 10 before are present in this door plate 20. The first web 10a and the second web 1c respectively includes at least one wrapping flange comprising a first wrapping flange 1d and a second wrapping flange 1e. The first wrapping flange 1d and the second wrapping flange 1e extend parallel and in the same direction to each other. As seen in FIG. 13, the second web 1c includes a first lip 1f extending perpendicular from second web 1c and extending in an opposite direction to the second wrapping flange 1e. A second lip 22 extends perpendicular from the first lip 1f and oriented in an opposite direction to the second web 1c. The second lip 22 includes a folded wall 24 via a bent 23. The folded wall 24 extends 180 degrees to the second lip and parallel to the second lip 22 forming a gap there between. The first web 10a also includes a folded wall 34 that is folded 180 degrees via a bent 32 resulting a gap between the folded wall 34 and the first web 10a. The folded wall 24 is therefore received between the folded wall 34 and the first web 10a while the folded wall 34 is received between the folded wall 24 and the second lip 22 creating a locking hem of four walls parallel to each other.

(20) It is envisioned that the second lip 22, the first web 10a, and the folded walls 24, 34 are compressed to each other in a similar fashion sheet metal is processed by bending and pressing to form metal hems. To further strengthen the connection between the two pieces of the door plate 20, the second lip 22, the first web 10a, and the folded walls 24, 34 are spot welded at different locations 50 from opposite sides. This prevents a thief from prying out the folded walls 24, 34 and further strengthens the connection there between.

(21) The following is a set of instructions to install the plate: Install the plate on the doorjamb leaving spaces open where an existing latch plates are located. Briefly hold the safety plate in place over the doorjamb and mark the top, bottom and center of the unit on the doorjamb. Cut the weather stripping that would be covered by the new plate. Remove the weather stripping that was cut and set aside. Gently pry the exterior and interior trim away from the doorjamb. Now slide the new plate into position and attach with four screws. Glue the weather strip back in place or use the self-sticking strip that came with the new plate. Adjust the moldings as needed.

(22) It should be understood that the strengthening hem 1h or the interlocking connection found in the safest door plate 20 strengthens the safety plate overall and prevents thieves from credit carding any door lock. Similar in concept, the first lip 10f and the second lip 10g together strengthen the safety plate and deter thieves from credit carding any door lock. Although it is envisioned to make the safety plate 1, 10, 20 from steel, the safety plate could as well be made from any known weldable material. While the fastening hole 1j is circular, they can be countersunk or counterbore to accommodate a respective fastener.
