System and apparatus for sanitizing a door opening device or other point of contact

Abstract

An apparatus for sanitizing a point-of-contact surface may include a housing configured to be affixed about at least a portion of said point of contact. The housing may have an interior in or through which the point of contact may be accessed and an anterior opening for access to the interior. The apparatus may further include one or more sources of a sanitizing agent configured to direct the sanitizing agent toward a location where at least a portion of the point-of-contact surface may be disposed. One or more of an anterior dome, an inner surface, and a posterior surface may also be configured to reflect the sanitizing agent toward the location where at least a portion of the point-of-contact surface may be disposed.

What is claimed is: 
     
         1 . An apparatus for sanitizing a point-of-contact surface, comprising:
 a housing configured to be affixed about at least a portion of said point-of-contact surface, having an interior in or through which said point-of-contact surface may be accessed and an anterior opening for access to said interior; and   one or more sources of a sanitizing agent configured to direct said sanitizing agent toward a location where at least a portion of said point-of-contact surface may be disposed.   
     
     
         2 . The apparatus of  claim 1 , said housing further comprising an inner surface configured to reflect said sanitizing agent toward a location where at least a portion of said point-of-contact surface may be disposed. 
     
     
         3 . The apparatus of  claim 2 , wherein said inner surface is substantially cylindrical. 
     
     
         4 . The apparatus of  claim 1 , further comprising a protective screen configured to separate at least one of said sources of a sanitizing agent from a central portion of said interior in or through which said point-of-contact surface may be accessed. 
     
     
         5 . The apparatus of  claim 4 , wherein said protective screen is substantially cylindrical. 
     
     
         6 . The apparatus of  claim 1 , further comprising:
 a posterior opening through which at least a portion of said point-of-contact surface may extend into said interior; and   a posterior surface configured to reflect said sanitizing agent toward a location where at least a portion of said point-of-contact surface may be disposed.   
     
     
         7 . The apparatus of  claim 1 , further comprising an anterior dome configured to reflect said sanitizing agent toward a location where at least a portion of said point-of-contact surface may be disposed. 
     
     
         8 . The apparatus of  claim 1 , further comprising one or more attachment structures for affixing said housing about at least a portion of said point-of-contact surface. 
     
     
         9 . The apparatus of  claim 1 , wherein at least one of said one or more sources of a sanitizing agent is a source of germicidal ultraviolet (UV) light. 
     
     
         10 . A system for sanitizing a point-of-contact surface, comprising:
 an apparatus configured to be affixed about at least a portion of said point-of-contact surface, comprising one or more sources of a sanitizing agent and having at least a first operating state in which said apparatus directs a first amount of said sanitizing agent toward said surface and a second operating state in which said apparatus directs a second amount of said sanitizing agent toward said surface; and   a switch configured to change the operating state of said apparatus.   
     
     
         11 . The system of  claim 10 , wherein said switch comprises a motion sensor. 
     
     
         12 . The system of  claim 10 , wherein said switch comprises a manual switch. 
     
     
         13 . The system of  claim 10 , wherein said switch comprises a remote activation system comprising:
 a remote control; and   a receiver coupled with said apparatus and responsive to said remote control.   
     
     
         14 . The system of  claim 10 , wherein said switch comprises a timer. 
     
     
         15 . The system of  claim 10 , wherein at least one of said one or more sources of a sanitizing agent is a source of germicidal ultraviolet (UV) light. 
     
     
         16 . A system for sanitizing a point-of-contact surface, comprising:
 an apparatus comprising:
 a housing configured to be affixed about at least a portion of said point-of-contact surface, having an interior in or through which said point-of-contact surface may be accessed and an anterior opening for access to said interior; and 
 one or more sources of a sanitizing agent; 
   wherein said apparatus has at least a first operating state in which said apparatus directs a first amount of said sanitizing agent toward a location where at least a portion of said point-of-contact surface may be disposed and a second operating state in which said apparatus directs a second amount of said sanitizing agent toward said location; and   a switch configured to change the operating state of said apparatus.   
     
     
         17 . The system of  claim 16 , wherein said switch comprises a motion sensor. 
     
     
         18 . The system of  claim 17 , wherein said switch further comprises a timer. 
     
     
         19 . The system of  claim 18 , wherein at least one of said one or more sources of a sanitizing agent is a source of germicidal ultraviolet (UV) light. 
     
     
         20 . The system of  claim 19 , wherein said apparatus further comprises a protective screen configured to divide said interior into a first compartment in which at least one of said one or more sources of a sanitizing agent is disposed, and a second compartment in or through which said opening device may be accessed.
