[0031] FIG. 3 shows a perspective view of the key guard system 100 of FIG. 1, according to an embodiment of the present disclosure. In a preferred embodiment, the base 112 and the retractable sheath 114 may be configured to secure the key within the retractable sheath 114 and prevent tampering with and otherwise unwanted removal of said key from said retractable sheath 114. As shown, the retractable sheath 114 may further include at least one retracting point 115 and a locking mechanism 118 configured to selectively lock the retractable sheath 114. In this embodiment the locking mechanism 118 may be configured to unlock upon receival of a signal from either the reader 120 (FIG. 2C) or the mobile device 130 (FIG. 2C) at the wireless connector 117.

[0032] 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.

[0033] FIG. 4 shows a perspective view of the key guard system 100 of FIG. 1, according to an embodiment of the present disclosure. The retractable sheath 114 may include a width 143 suitable for receiving the key 5. Further, the base 112 may be connected to a second-end 144 of the retractable sheath 114. In this embodiment, a head of the key is inserted into, and concealed by the base 112. In this embodiment, the base 112 may include an elongated holding piece, such as a screw or pin, to hold the key 5 in place. In this example, the screw or pin may receive an aperture located on the head of the key 5.

[0034] 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.

[0035] 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.

[0036] FIGS. 5A-5B show a perspective views of the key guard system 100 of FIG. 1, according to a different embodiment of the present disclosure. Another embodiment of the key guard system 200 is also disclosed herein.

In one embodiment, the retractable sheath 114 may include the power source 116, the wireless connector 117 disposed within the key cover 110 and communicably coupled to the power source 116, the at least one retracting point 115 (FIG. 3) and the locking mechanism 118. In one embodiment, the locking mechanism 118 may be configured to lock the retractable sheath 114 and unlock, causing the retractable sheath 114 to retract, as above. However, as shown, in this alternative embodiment, the locking mechanism 118 may include a retractable cord 212 that is selectively latched onto the retractable sheath 114 and locking key 5 within the retractable sheath 114. Upon receival of the signal, the locking mechanism 118 may be electro-mechanically energized to unlatch the retractable cord 212 from the retractable sheath 114, thus unlocking the retractable sheath 114 and allowing use of the key 5 (FIG. 4). As shown, the retractable cord 212 may be selectively locked into an aperture located on the base 112.

[0037] 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.

[0038] 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.

[0039] 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.
