Abstract

A device for cleaning feet, socks, or shoes comprises a housing, a target surface, and at least one ultraviolet light source. The target surface is supported by the housing and is adapted to be walked upon by an individual. The at least one ultraviolet light source is supported by the housing and adapted to direct ultraviolet light waves onto the target surface such that the ultraviolet light waves interact with the feet of the individual walking upon the target surface. The light waves kill or deactivate harmful germs or transmissible diseases disposed on the target surface, or carried by the feet or the socks of the individual, thereby preventing the harmful germs from spreading and causing harm to other individuals or animals.

Claims

1. A device, comprising:

a housing;

a target surface of discrete dimensions supported by the housing and adapted to be walked upon by an individual; and

at least one ultraviolet light source supported by the housing and adapted to direct ultraviolet light waves onto the target surface such that the ultraviolet light waves interact with the feet of the individual walking upon the target surface, wherein the ultraviolet light waves kill or deactivate harmful germs or transmissible diseases disposed on the target surface, or carried by the feet or the socks of the individual, thereby preventing the harmful germs from spreading and causing harm to other individuals or animals.

2. The device of claim 1, further comprising a means for moving air through the target surface and adjacent the at least one ultraviolet light source to kill or deactivate air born germs or transmissible diseases released in the area of the target surface.

3. The device of claim 2, further comprising a germicidal filter disposed adjacent to the target surface such that at least some of the air circulated by the air circulation means travels through the germicidal filter.

4. The device of claim 2, wherein the target surface comprises a porous surface and the means for circulating air through the target surface comprises a fan for drawing air downward through the target surface.

5. The device of claim 1, further comprising a means for emitting a germicidal chemical in the area of the target surface to kill or deactivate harmful germs or transmissible diseases.

6. The device of claim 5, wherein the germicidal chemical comprises an antibiotic chemical.

7. The device of claim 1, wherein the ultraviolet light waves comprise at least one of UV-C light waves, UV-B light waves, and UV-A light waves.

8. The device of claim 1, wherein the housing comprises a pair of channels disposed on opposite sides of the target surface, the at least one ultraviolet light source and a light reflector disposed within at least one of the channels.

9. The device of claim 8, wherein the channels include elongated openings adjacent the target surface for directing the ultraviolet light waves toward the target surface.

10. The device of claim 1, wherein the target surface comprises a removable grate to enable the removal of trapped debris from beneath the target surface.

11. A device, comprising:

a housing defining a base plate, and first and second channels extending along opposite sides of the base plate;

a target surface of discrete dimensions supported by the base plate of the housing and adapted to be walked upon by an individual;

a first ultraviolet light source and a light reflector supported by the housing within the first channel; and

a second ultraviolet light source and a light reflector supported by the housing within the second channel,

the first and second channels of the housing shaped and configured with the light reflector to reflect ultraviolet light waves generated by the first and second ultraviolet light sources onto the target surface such that the ultraviolet light waves interact with the feet of the individual walking upon the target surface to kill or deactivate harmful germs or transmissible diseases disposed on the target surface, or carried by the feet or socks of the individual, thereby preventing the harmful germs or transmissible diseases from spreading and causing harm to other individuals or animals.

12. The device of claim 11, wherein the first and second channels of the housing define first and second elongated openings extending the length of the target surface.

13. The device of claim 11, further comprising a means for moving air through the target surface and into the first and second channels adjacent to the first and second ultraviolet light sources to kill or deactivate air born germs or transmissible diseases released in the area of the target surface.

14. The device of claim 13, further comprising a germicidal filter disposed adjacent to the target surface such that at least some of the air circulated by the air circulation means travels through the germicidal filter.

15. The device of claim 13, wherein the target surface comprises a porous surface and the means for circulating air through the target surface comprises a fan for drawing air downward through the target surface.

16. The device of claim 11, further comprising a means for emitting a germicidal chemical in the area of the target surface to kill or deactivate harmful germs.

17. The device of claim 16, wherein the germicidal chemical comprises an antibiotic chemical.

18. The device of claim 11, wherein the ultraviolet light waves comprise at least one of UV-C light waves, UV-B light waves, and UV-A light waves.

19. The device of claim 11, wherein the target surface comprises a removable grate supported by the base plate of the housing to enable the removal of trapped debris from beneath the target surface.

20. A method of killing or deactivating harmful germs or transmissible diseases disposed on a target surface of a cleaning device, or carried by the feet or socks of an individual walking on the target surface, the method comprising:

generating ultraviolet light waves with one or more ultraviolet light sources disposed within channels disposed on opposing sides of the target surface of the cleaning device; and

at least one of the following;

deflecting the ultraviolet light waves out of the channels and toward the target surface such that the ultraviolet light waves interact with at least one of the target surface, the individuals feet walking across the target surface, and the socks worn by the individual walking across the target surface to kill or deactivate harmful germs or transmissible diseases disposed on the target surface or carried by the feet or socks of the individual;

circulating air through the target surface and toward the one or more ultraviolet light sources disposed within the channels to kill or deactivate air born germs or transmissible diseases released in the area of the target surface;

emitting a germicidal chemical in the area of the target surface to kill or deactivate harmful germs or transmissible diseases.
