Door security system

Abstract

A security system for use with the door with a door jamb has a plate member mountable in the door jamb adjacent hinges of the door. The plate member has a protrusion extending outwardly therefrom. A bracket member has a slot therein for receipt of the protrusion of plate member. The bracket member has first and second wings extending outwardly therefrom so as to bear against the door and surface adjacent the door when the bracket member is received by the plate member. The bracket member has an alarm receiver on a front side thereof. A vibration-activated alarm is removably received by the alarm receiver. The vibration activated alarm can be utilized during travel and is attachable to any door, even without the plate member and bracket member.

DETAILED DESCRIPTION OF THE INVENTION

(9) Referring to FIG. 2, there is shown a top view of the bracket member 42 of the door security system 40 of the preferred embodiment of the present invention. The bracket member 42 includes a middle portion, or planar surface, 44. A first wing 46 extends angularly outwardly from the middle portion 44, while a second wing 48 extends angularly outwardly from the middle portion 44 at an end opposite thereof. The first wing 46 and second wing 48 preferably have ends 50. The ends 50 of the first and second wings 46 and 48 are preferably coplanar with the middle portion 44 of the bracket member 42.

(10) Preferably, the bracket member 42 is constructed of aircraft aluminum. In a preferred embodiment of the present invention, the ends 50 of the wings 46 and 48 are either constructed of a non-metallic material or have a non-metallic coating thereon. The coating is preferably a soft material such that when the ends 50 of the wings 46 and 48 are bearing against the door surface or wall surface adjacent the door, damage does not occur to the door or wall surface.

(11) FIGS. 2 and 3 also show how the bracket member 42 of the door security system 40 has a plate member receiving slot 52. As shown in FIG. 3, the plate member receiving slot 52 extends approximately halfway through the middle portion 44 of the bracket member 42.

(12) FIGS. 2 and 3 also show the alarm receiver 56. In a preferred embodiment of the present invention, the alarm receiver 56 comprises a pair of arms 54 which extend outwardly from the middle portion 44 of the bracket member 42. Preferably, the alarm receiver 56 includes a pair of opposing slots 57. The pair of opposing slots 57 are suitable for receiving a portable alarm, which is described hereinbelow. Preferably, the slots 57 are integrally formed with the arms 54 and with the remainder of the bracket member 42 so as to efficiently transfer vibration forces from the door through the bracket member and to the vibration alarm so as to the trigger the vibration alarm in the event of an attempted break-in.

(13) Referring to FIGS. 4 and 5, there is shown the plate member 58 of the door security system 40 of the present invention. The plate member 58 includes a protrusion 60. A plurality of screw holes 62 are formed through the plate member 58. Referring to FIG. 5, it can be seen how the protrusion 60 includes a groove 60a and a lobe 60b. The groove 60a traverses the slot 52 of the bracket member 42, while the lobe 60b is sized so as to prevent the bracket member 42 from coming off the plate member 58 when the protrusion 60 is received in the slot 52 of the bracket member 42.

(14) FIG. 5 illustrates how the plurality of screw holes 62 of the plate member 58 are extruded so as to extend outwardly from the surface of the plate member 58. When secured in the door jamb with screws, the extruded screw holes 62 cut into the surface of the doorjamb, thus enhancing the effectiveness of the door security system 40, and thus the strength of the door. The bracket member and the plate member of the door security system 40 are intended to be used in a permanent manner, and probably would not be suitable for use during travel, given the need to secure the plate member with a plurality screws.

(15) Referring to FIG. 6, there is shown the vibration alarm 64 of the door security system 40 of the present invention. The vibration alarm 64 is a vibration-activated alarm, is preferably sized similar to a small cellular telephone. The vibration alarm 64 includes a screen and speaker area 66, with a control panel 68. As shown in FIG. 6, the vibration alarm 64 is received by the alarm receiver 56 of the bracket member 42. FIG. 6 shows the alarm receiver 56 in the form of a pair of opposing slots 57. The vibration alarm 64 can optionally be attached or mounted to the bracket member 42 in a number of ways. Preferably however, the vibration alarm 64 is attached in such a manner that the vibration from an attempted break-in is transferred from the bracket member 42 to the vibration alarm 64. Alternately, the vibration alarm 64 can be permanently attached to the bracket member 42.

(16) Preferably, the vibration alarm 64 is removable so as to be used during travel. Referring to FIG. 7, there is shown a rear perspective view of the vibration alarm 64 of the preferred embodiment of the present invention. In FIG. 7, it can be seen how an adhesive 69 is positioned on the back side of the vibration alarm 64. The adhesive 69 is positioned centrally on the back of the vibration alarm 64 so as to not interfere with the alarm receiver 56 of the bracket member 42. The adhesive 69 is utilized to attach the vibration alarm 64 to a door or other surface remote from the plate member 58. For example, the vibration alarm 64 can be utilized in a hotel. If the door is contacted, then the vibration alarm 64 emits an audible sound so as to deter a possible thief or assailant. The adhesive 69 can also be any number of attachment means, including magnets and the like.

(17) FIG. 7 also shows how the vibration alarm 64 has a thickness T. The thickness T is suitable for receipt within the pair of opposing slots 57 of the alarm receiver 56. Preferably, the thicknesses are such that the vibration alarm 64 us secured by interference fit. However, horizontal bottom portions could be provided in the pair of opposing slots 57 such that the vibration alarm 64 sits thereon. The interference fit is preferred in that it provides for better transfer of vibration during an attempted break-in.

(18) The vibration alarm 64 preferably uses a cellular or wireless service that may not need to be monitored on a constant basis. As such, users of the door security system of the present invention can avoid paying monthly fees to security companies.

(19) Referring to FIG. 8, there is shown a holder 70 for the bracket member 42. The holder 70 can be secured to an area adjacent the door upon which the security system 40 is being used. Preferably, the holder 70 includes a pair of screw holes 72 such that the holder 70 can be securely mounted to the wall. Similar to the plate member, the holder 70 has a protrusion 74 extending outwardly therefrom. The protrusion 74 is suitable for receiving the slot 52 of the bracket member 42. A lip 76 is provided on the protrusion 74 so as to prevent the bracket member 42 from coming off of the holder 70. The holder 70 enhances the ease and convenience of use of the door security system 40 of the present invention. The protrusion 74 of the holder 70 is sized such that it prevents the wings of the bracket member from contacting the wall surface when the bracket member 42 is being stored on the holder 70.

(20) The door security system of the present invention is very versatile in that it allows for a very secure entry at one's home or place of business, and also allows for a simple, portable alarm system. Further, the door security system of the present invention allows for easy removal of the vibration alarm such that the vibration alarm can be used during travel or when outside of the home for other reasons.

(21) The foregoing disclosure and description of the invention is illustrative and explanatory thereof. Various changes in the details of the illustrated construction can be made within the scope of the appended claims without departing from the true spirit of the invention. The present invention should only be limited by the following claims and their legal equivalents.
