The following includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art nor material to the presently described or claimed inventions, nor that any publication or document that is specifically or implicitly referenced is prior art.
The present invention relates generally to the field of key covers and more specifically relates to a key guard system.
A key is a device that is used to operate a lock (such as to lock or unlock it). A typical key is a small piece of metal consisting of two parts: the blade, which slides into the keyway of the lock and distinguishes between different keys, and the bow, which is left protruding so that torque can be applied by the user. A key is usually intended to operate one specific lock or a small number of locks that are keyed alike, so each lock requires a unique key. The key serves as a security token for access to the locked area; only persons having the correct key can open the lock and gain access. Often times, keys are replicated, and copies may be used to open corresponding locks; sometimes this is undesirable due to security reasons. A suitable solution is desired.
U.S. Pat. No. 2,587,037 to Casper Glubiak relates to a self-ejecting key. The described self-ejecting key includes locking devices and keys used in connection therewith. An object of the invention is to provide a novel and improved locking device and key, in which the key is automatically separated from the locking device whenever the key is turned to a predetermined position in the locking device.
In view of the foregoing disadvantages inherent in the known key cover art, the present disclosure provides a novel key guard system. The general purpose of the present disclosure, which will be described subsequently in greater detail, is to provide a key guard sheath to prevent the unwanted replication of keys.
A key cover is disclosed herein including a base and a retractable sheath. The retractable sheath may include at least one retracting point, a power source, a wireless connector, and a locking mechanism. Further a reader may be provided having a powerer. The wireless connector may be disposed within the key cover and in communication with the reader which may be proximal to a keyhole. The reader and the wireless connector may further be in communication with an application hosted on a mobile device. The locking-mechanism may be configured to selectively lock the retractable sheath and selectively unlock upon receival of a signal from at least one of the reader and the application hosted on the mobile device. Preferably, the base and the retractable sheath are configured to secure the key within the retractable sheath and prevent tampering with and otherwise unwanted removal of the key from the retractable sheath.
For purposes of summarizing the invention, certain aspects, advantages, and novel features of the invention have been described herein. It is to be understood that not necessarily all such advantages may be achieved in accordance with any one particular embodiment of the invention. Thus, the invention may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other advantages as may be taught or suggested herein. The features of the invention which are believed to be novel are particularly pointed out and distinctly claimed in the concluding portion of the specification. These and other features, aspects, and advantages of the present invention will become better understood with reference to the following drawings and detailed description.
The figures which accompany the written portion of this specification illustrate embodiments and methods of use for the present disclosure, a key guard system, constructed and operative according to the teachings of the present disclosure.
The various embodiments of the present invention will hereinafter be described in conjunction with the appended drawings, wherein like designations denote like elements.
As discussed above, embodiments of the present disclosure relate to a key cover and more particularly to a key guard system as used to improve the security of lending keys and preventing unwanted replication of the keys.
Generally, the present device is a guard or sheath covering a key which prevents the key from being copied so it can be used without authorization. The device includes a locking mechanism which effectively prevents the device from being removed from the key. The locking mechanism may include a spin-lock, fingerprint lock, a lock and key on a base of the device, or other suitable locking mechanisms. The key guard system may include a spring-loaded cover or a folding telescopic cover.
The sheath may be a retractable sheath to allow access to the key. The retractable sheath be may be locked in place until in very close proximity to a reader which may be a separate piece that works with the retractable sheath and allows it to be retracted. The reader may be moved to any locking mechanism, so the retractable sheath can be used with multiple keys. Once the key is placed in the base of the retractable sheath, retracting points located in the retractable sheath may be placed over teeth of the key and locked into the base to hold the key in place. This may prevent access to the key while out of the range of the reader and provide security from copying and misuse of the key.
Preferably, the retractable sheath and the reader may include BLUETOOTH® technology (or other suitable equivalent) to allow for connection between the retractable sheath and the reader. The reader may be positioned on an interior of a door. The retractable sheath may then be able to open when in close proximity to the reader via an electronic handshake (being recognized). In another embodiment, an RFID chip may be included in the retractable sheath itself and the reader may read the RFID chip; the reader may be located on the interior of the door. The retractable sheath and the reader may be able to connect to a smartphone device and controlled via the smartphone device. In one embodiment, the retractable sheath may include a small rechargeable battery capable of many hours of use. Further, the reader may be powered by AA or AAA batteries. The reader may be configured to track when the retractable sheath is activated and is able to be turned on and off through the smartphone device. This allows for full control of a time window someone can use the device.
Referring now more specifically to the drawings by numerals of reference, there is shown in
Further, the reader 120 may include a powerer 122. The powered may be at least one battery. The at least one battery may be disposable or rechargeable. Preferably, the at least one battery may be an AA or AAA battery. In one embodiment, the reader 120 may be configured proximal to a keyhole. Preferably, the reader 120 may be located on an inside portion of a door 10 such that an outsider is unable to tamper with or view the reader 120.
The wireless connector 117 of the retractable sheath 114 may in communication with the reader 120. In a preferred embodiment, the reader 120 may use short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz (BLUETOOTH® technology) to communicate with the wireless connector 117 of the retractable sheath 114. The retractable sheath 114 is in communication with the reader 120 and may be configured to retract when in close proximity to the reader 120 so that when the wireless connector 117 of the retractable sheath 114 receives a wireless signal from the reader 120, the wireless connector 117 actuate the retractable sheath 114 to retract, thereby exposing the key and allowing use of the key 5. To prevent unauthorized use of the key 5, the retractable sheath 114 does not retract when out of range from the reader 120. To perform the retraction, the retractable sheath 114 may be spring-loaded for automatic retraction and extension of the retractable sheath 114. In another embodiment, the retractable sheath 114 may comprise a telescopic retractable sheath 114. The telescopic retractable sheath 114 may be spring-loaded or may be manually retracted. Those with ordinary skill in the art will now appreciate that upon reading this specification and by their understanding the art of wireless communication such as BLUETOOTH® as described herein, methods of facilitating such communication to achieve electro/mechanical results/manipulations will be understood by those knowledgeable in such art.
Further, the reader 120 and the wireless connector 117 may be in communication with an application hosted on a mobile device 130. As above, the reader 120, the wireless connector 117 and the mobile device 130 may wirelessly communicate via BLUETOOTH® technology. In one embodiment, the reader 120 may be configured to remotely control the key cover 110 the said mobile device 130. For example, a user may be able to connect to the reader 120 via the mobile device 130 and control actuation of the retractable sheath 114. The user may be able to set timers via the application on the mobile device 130 to allow for a specified period in which the retractable sheath 114 remains retracted, the reader 120 BLUETOOTH® remains active, etc.
The at least one retracting point 115 may comprise two retracting points 115. The two retracting points 115 may be elastic, or spring mechanisms which hold the retractable sheath 114 under spring pressure when the retractable sheath 114 is in an extended position such that when the locking mechanism 118 is locked, or when the wireless connector 117 loses the signal, the retractable sheath 114 is held in the extended position and is highly resistant to manual movement. Thus, a user is unable to manually retract the retractable sheath 114 themselves. In one embodiment, the locking mechanism 118 may override the spring pressure of the two retracting points 115 when actuated. In one embodiment, the locking mechanism 118 may include a latch that is depressed when actuated, such that the two retracting points 115 are able to relax and retract the retractable sheath 114. In another embodiment, the locking mechanism 118 may include a motor powered by the power source 116. The motor may be actuated upon receival of the signal via the wireless connector 117 which may then actuate retraction of the retractable sheath 114. Further, in another embodiment, the locking mechanism 118 may include high pressure elastics configured to hold the retractable sheath 114 in a closed position under spring pressure.
The retractable sheath 114 is placed over a body of the key 5 and conceals bitting cuts 15 of the key 5 to prevent use of the key 5 when the retractable sheath 114 is in the extended position. The retractable sheath 114 may be locked onto the base 112 via two adjustable buttons. In this example, the base 112 may include locking apertures, and the retractable sheath 114 may include locking points configured to mate with the locking apertures, such that the retractable sheath 114 is able to lock to the base 114 when the locking points are mated with the locking apertures.
Once the retractable sheath 114 is retracted, the retractable sheath 114 retracts towards the base 112, exposing the bitting cuts 15 of the key 5 via a first-end 145 of the retractable sheath 114. In addition, in one embodiment, the base 112 may further include a clip 146. The clip 146 may be used for fastening to the key guard system 100 to a surface, a key ring, or a user.
Preferably, the key cover 110 may be made from a weatherproof material such that the key cover 110 is able to be left outside of a building and act as a conventional lockbox. For example, the weatherproof material may be plastic, metal, etc. The retractable cord 212 may allow the key cover 110 to be attached to the outside of the building. The retractable lock is located on the side of the base, as shown. It is very small as it only holds a retractable cord that stretches about 6 inches (or slightly more or slightly less). This feature allows the key cover 110 to be a fully functioning lockbox as well as providing additional security.
As above, the wireless connector 117 may be disposed within the key cover 110 and in communication with an application hosted on the mobile device 130. The wireless connector 117 may use short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz (BLUETOOTH® technology) configured to communicate with BLUETOOTH® on the mobile device 130. Similar to the key guard system 100 as above, the locking mechanism 118 may be configured to unlock upon receival of a signal from the application hosted on the mobile device 130. For example, in one embodiment, the user may be prompted to enter a code on the mobile device 130. This may then be transmitted via BLUETOOTH® to allow for unlocking of the locking mechanism 118.
The embodiments of the invention described herein are exemplary and numerous modifications, variations and rearrangements can be readily envisioned to achieve substantially equivalent results, all of which are intended to be embraced within the spirit and scope of the invention. Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientist, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application.
The present application is a Continuation-in-Part and is related to and claims priority to pending U.S. Non-Provisional patent application Ser. No. 15/663,634 filed Jul. 27, 2017, which is incorporated by reference herein in their entirety.
