Security device and security system

Abstract

A security device and system includes a substantially flat body with an opening formed therein. The opening has a predetermined length and a predetermined height such that an elongated end of a key passes through the opening and a head end of the key does not pass through the opening. A user gripping the security device may then use the elongated end of the key extending outward therefrom as a weapon or tool for self-defense.

         13 . The security device of  claim 12 , wherein the connector is made of a flexible material such that the substantially flat body is movable relative to the key ring to allow the elongated end of the key on the key ring to pass through the opening in the substantially flat body. 
     
     
         14 . A security system comprising:
 a key including,
 an elongated end; and 
 a head end opposite the elongated end; and 
   a security device including a body, the body including,
 a front surface; and 
 a rear surface positioned opposite to the front surface, wherein 
 an opening is formed in the body between the front surface and the rear surface, the opening having a predetermined length and a predetermined height such that the elongated end of the key is passable through the opening and a substantial portion of the elongated end extends out from the front surface of the body, and the head end of the key is not passable through the opening. 
   
     
     
         15 . The security system of  claim 14 , wherein substantially the entire elongated end of the key extends out from the front surface of the body. 
     
     
         16 . The security system of  claim 15 , wherein the front surface and the rear surface of the body are curved for ease in gripping. 
     
     
         17 . The security system of  claim 15 , further comprising
 a key ring configured to carry the key; and   a connector secured to the body and configured to connect the body to the key ring.   
     
     
         18 . The security system of  claim 17 , wherein the connector is made of a flexible material such that the body is movable relative to the key ring to allow the elongated end of the key on the key ring to pass through the opening in the body. 
     
     
         19 . A security system comprising:
 a key including,
 an elongated end; and 
 a head end opposite the elongated end; and 
   a security device having a substantially flat body, the substantially flat body including an opening with a predetermined length and a predetermined height such that the elongated end of the key is passable through the opening and the head end of the key is not passable through the opening.   
     
     
         20 . The security system of  claim 19 , wherein the substantially flat body further comprises:
 a front surface; and   a rear surface positioned opposite the front surface, wherein a substantial portion of the elongated end of the key extends out from the front surface after passing through the opening.   
     
     
         21 . The security system of  claim 20 , wherein substantially the entire elongated end of the key extends out from the front surface of the body. 
     
     
         22 . The security system of  claim 20 , wherein the front surface and the rear surface of the substantially flat body are curved for ease in gripping. 
     
     
         23 . The system device of  claim 20 , further comprising:
 a key ring configured to carry the key; and   a connector secured to the substantially flat body and configured to connect the substantially flat body to the key ring.   
     
     
         24 . The security system of  claim 23 , wherein the connector is made of a flexible material such that the substantially flat body is movable relative to the key ring to allow the elongated end of the key on the key ring to pass through the opening in the substantially flat body. 
     
     
         25 . A method of self defense comprising steps of:
 providing a key with an elongated end and a head end opposite the elongated end;   providing a security device including a body with an opening formed therein;   passing the elongated end of the key through the opening in the substantially flat body such that a substantial portion of the elongated end extends out from the body;   preventing the head end of the key from passing through the opening; and   gripping the substantially flat body such that the substantial portion of the elongated end of the key extends outward.   
     
     
         26 . The method of self defense of  claim 18 , wherein the step of providing the security device further comprises forming the opening in the body with a predetermined length and a predetermined height such that the substantial portion of the elongated end of the key passes through the opening and the head end of the key does not pass through the opening.
