Abstract

Various implementations of the invention are directed toward a sanitizing door handle and/or components of such sanitizing door handle. Some implementations of the invention are directed toward a manual sanitizing door handle while some implementations of the invention are directed toward an auto-sanitizing door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto an exterior surface of the sanitizing door handle in connection with an operation of the door handle to sanitize the door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto a user'"'"'s hand(s) in connection with an operation of the door handle to sanitize the user'"'"'s hand(s).

Claims

1. A door handle comprising:

a door handle grip comprising a grip wall, wherein the grip wall forms an interior grip chamber, wherein the grip wall also forms a plurality of grip holes that communicate the interior grip chamber of the grip wall with an exterior surface of the grip wall;

a fluid container;

a tubing having a first end and second end, wherein the first end of the tubing is configured to receive a fluid from the fluid container and to communicate the fluid to the second end of the tubing, wherein the door handle grip is configured to receive the fluid from the second end of the tubing;

a pump configured to force the fluid out of the fluid container into the first end of the tubing, through the tubing to the second end of the tubing, into the interior grip chamber of the door handle grip, through the plurality of grip holes and onto an exterior of the grip wall.

2. The door handle of claim 1, further comprising a fluid chamber housing configured to house the fluid container.

3. The door handle of claim 2, wherein the fluid chamber housing is configured separate from and external to the door handle grip.

4. The door handle of claim 3, wherein the fluid chamber housing is configured to be mounted on a same side of a door as the door handle grip.

5. The door handle of claim 3, wherein the fluid chamber housing is configured to be mounted on an opposite side of a door as the door handle grip.

6. The door handle of claim 3, wherein the fluid chamber housing is configured to be mounted on a wall near the door handle grip.

7. The door handle of claim 1, wherein the tubing comprises a braided cover.

8. The door handle of claim 1, further comprising a door latch actuator operatively coupled to the door handle.

9. The door handle of claim 8, further comprising a door latch linkage operatively coupling the door latch actuator to the door handle.

10. The door handle of claim 1, wherein the fluid container comprises a sterilizing, disinfecting, antiseptic, antimicrobial, sanitizing or cleaning fluid.

11. The door handle of claim 1, wherein the fluid container comprises an alcohol-based sanitizing fluid.

12. The door handle of claim 1, wherein the fluid container comprises a non-alcohol-based sanitizing fluid.

13. The door handle of claim 4, wherein the fluid comprises a gel-like carrier ingredient.

14. The door handle of claim 1, wherein the fluid container is refillable.

15. The door handle of claim 1, wherein the fluid container is replaceable.

16. The door handle of claim 1, further comprising a distribution manifold coupled to the second end of the tubing, wherein the distribution manifold communicates fluid from an interior of distribution manifold to an exterior of distribution manifold via a plurality of distribution holes.

17. The door handle of claim 1, further comprising a check valve disposed along the tubing between the fluid container and the second end of the tubing, the check valve configured to permit flow of the fluid through the tubing from the fluid container to the second end of the tubing and to inhibit flow of the fluid through the tubing back to the fluid container.

18. The door handle of claim 1, wherein the pump is a mechanically actuated pump.

19. The door handle of claim 1, wherein the pump is a electrically actuated pump.

20. The door handle grip, wherein the pump is actuated when a user operates the door handle.
