BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the field of home security. More particularly, the present invention relates to a door securement apparatus. Even more particularly, the present invention relates to a door securement apparatus with a removable alarm that can be utilized during travel.
2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98.
Home invasions and break-ins are a common concern amongst the people of the United States. It is very important for people to maintain a good sense of security in one's home, and also during travel. Travelers often find themselves in lodging wherein they are in a room protected only by a simple lock. In many cases, the simple locks are supplemented by chains or other relatively ineffective door securement devices. Supplemental devices which enhance the security, or sense thereof, include portable locks, alarm devices which do not interfere with the operation of the door, and door brace systems.
Various patent have issued in the past relating to portable locks and alarms. For example, U.S. Pat. No. 4,300,796, issued on Nov. 17, 1981 to Lane, describes an adjustable door and window security prop. In the device of the Lane patent, adjustable large and small diameter tubular members are telescopic engaged with each other. A U-shaped member is attached to one of these legs so as to engage the door handle. A stop is provided at the bottom of the member for frictional engagement with the floor. A lock structure is provided so as to cause the fixed engagement between the tubular members.
Some patents, such as U.S. Pat. No. 4,358,758, issued on Nov. 9, 1982 to Morton, describe combination door locks and alarms. Generally speaking, these types of devices are braces which engage with both the door handle and the floor.
Various patents have issued in the past relating to portable alarms which can be utilized in different settings. For example, U.S. Pat. No. 8,643,486, issued on Feb. 4, 2014 to Hess, describes a portable alarm device which can be used in a hotel. The alarm device issues an audible siren and is cellular-capable. The portable alarm device may be attached to surfaces using a variety of means including magnetic attachments.
U.S. Patent Publication No. 2008/0297367 published on Dec. 4, 2008 to Chen, describes a multi-purpose portable alarm which can be used as a vibration-activated door alarm.
U.S. Pat. No. 5,712,623, issued on Jan. 27, 1998 to Kumai et al., discloses an alarm device. The alarm device is hung on a doorknob and is configured to emit an alarm upon detecting human body contact or movement of the doorknob. The alarm device has a data processor and an electrical display for displaying data processed by the data processor and information related to the operation of the alarm. A hanging member is rotatably mounted to the alarm device so as to suspend the alarm device from the doorknob.
U.S. Pat. No. 5,309,145, issued on May 3, 1994 to Branch et al., describes a travel convenience and security device. In the security device, a clock, a lamp, an alarm, a motion detector, as well as a smoke alarm are combined in a single device. If motion occurs under circumstances suggesting that an intruder is present or smoke is detected, then an alarm signal and the degree of illumination alert the user to a potential security concern.
Various other patents issued in the past relating to door security and alarms, including U.S. Pat. Nos. 5,392,026, 4,483,558, 4,563,027, and 4,607,253. These patents generally fall into the door brace category.
Various apparatuses have been developed in the past related to enhancing the strength, and thus the security, of a conventional door. For example, various arrangements utilizing bars, chains, and the like have been utilized in the past to enhance security and the strength of a door. These solutions can sometimes be effective, however are often bulky and cumbersome to use. Further, some of the door security enhancements, such as a simple chain door fastener provide a false sense of security.
Referring to FIGS. 1 and 1A, there is shown a door securement device in the prior art. The device shown in FIGS. 1 and 1A is considered by the applicant to strongly enhance the strength of a door, preventing it from being kicked in and coming off its hinges.
FIGS. 1 and 1A show the prior art door securement apparatus 10. The apparatus 10 includes a plate member 12 (shown more clearly in FIG. 1A) and a bracket member 14. The plate member 12 is mounted in the door jamb 16. The plate member 12 has a protrusion 26 extending outwardly therefrom. The plate member 12 also contains a plurality of screw holes 24 formed therethrough. Screws are utilized to secure the plate member 12 in the door jamb of a door adjacent the door hinges. When the door is closed, the protrusion 26 extends outwardly from the door jamb to the interior of the room.
The bracket member 14 has a slot 18 formed therein. The slot 18 is suitable for positioning over and receiving the protrusion 26 of the plate member 12. FIG. 1 shows how the protrusion 26 is adjacent the door jamb 16. The slot 18 of the bracket member 14 is shown as being moved downwardly towards the protrusion 26. When the protrusion 26 is received in a slot 16 of the bracket member 14, the bracket member 14 is secured against the door 28 on one end thereof and the doorframe or wall 30 on an opposite end.
The bracket member 14 has a first wing 20 and second wing 22 extending outwardly therefrom. The first wing 20 is shown as bearing against the door 28, while the second wing 22 is shown as bearing against the doorframe or wall 30 on the other side of the door jamb 16.
FIG. 1A shows how the protrusion 26 of the plate member 12 is formed such that a groove of the protrusion is received within the slot 18, while the end of the protrusion 26 holds the bracket member 14 in place.
This apparatus proves successful in preventing intrusions, and was believed to have been sold under the trademark “Cops Lock” or “Eagle Lock”. It is the applicant's belief that the product is no longer available on the market. Additionally, it is believed that there was a patent or patent application related to this apparatus or a similar apparatus. However, Applicant has been unable to identify or find such a patent or patent application after a diligent search.
The device shown in FIGS. 1 and 1A, while very effective in enhancing the strength of the door, does not provide an alarm function. Further, the wings of the bracket member 14 of the prior art door securement apparatus 10 can damage the door or wall surface.
It is an object of the present invention to provide a door security system which enhances the physical strength of the door and doorframe.
It is another object of the present invention to provide a door security system which both enhances the physical strength of the door and provides for an alarm function.
It is yet another object of the present invention to provide a door security system which does not damage the door or wall surface adjacent thereof in the event that a break-in is attempted.
It is another object of the present invention to provide a door security system which provides for increased strength over the apparatuses of the prior art.
It is another object of the present invention to provide a door security system which has a removable alarm for use during travel.
It is another object of the present invention to provide a door security system which is easy to use.
These and other objects and advantages of the present invention will become apparent from a reading of the attached specification and appended claims.

DETAILED DESCRIPTION OF THE INVENTION
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
