Abstract
The invention relates to a door handle (10) with an automatic cleaning function. The door handle comprises a handle (12) and a housing (14), the handle being mounted to the housing by a mounting mechanism (16,18) and being movable relative to the housing between a rest position and an activated position. The handle is resiliently biased to the rest position. The housing (14) contains a primary reservoir (34) for a cleaning agent and the door handle has a secondary reservoir (44) for the cleaning agent, the secondary reservoir being located adjacent to the handle (12). A part of the mounting mechanism is connected to a pump mechanism (36) for driving the cleaning agent from the primary reservoir (34) to the secondary reservoir (44). The handle (12) has a longitudinal axis (A-A) and is rotatable about the longitudinal axis relative to the mounting mechanism (16,18). The mounting mechanism has a rotation mechanism (62,64,66,72,74) which controls the rotation of the handle (12), the rotation mechanism substantially preventing rotation of the handle as the handle moves from its rest position to its activated position and driving the handle to rotate as the handle moves from its activated position to its rest position.
Claims (30)
1. A door handle with an automated cleaning function comprising a handle and a housing, the handle being mounted to the housing by a mounting mechanism and being movable relative to the housing between a rest position and an activated position, the handle being resiliently biased to the rest position, the housing containing a primary reservoir for a cleaning agent, the door handle having a secondary reservoir for the cleaning agent, the secondary reservoir being located adjacent to the handle, a part of the mounting mechanism being connected to a pump mechanism for driving the cleaning agent from the primary reservoir to the secondary reservoir, the handle having a longitudinal axis and being rotatable about the longitudinal axis relative to the mounting mechanism, the mounting mechanism having a rotation mechanism which controls the rotation of the handle, the rotation mechanism substantially preventing rotation of the handle as the handle moves from its rest position to its activated position and driving the handle to rotate as the handle moves from its activated position to its rest position.
2. A door handle according to claim 1 in which the pump mechanism generates a positive pressure to drive the cleaning agent from the primary reservoir to the secondary reservoir.
3. A door handle according to claim 1 or claim 2 in which the cleaning agent in the secondary reservoir contacts the handle.
4. The door handle according to any one of claims 1-3 in which the secondary reservoir is carried by the mounting mechanism.
5. The door handle according to any one of claims 1-4 in which the secondary reservoir moves with the handle between its rest and activated positions.
6. The door handle according to any one of claims 1-5 in which the secondary reservoir comprises a trough which accommodates a part of the handle.
7. The door handle according to any one of claims 1-6 in which the secondary reservoir contains an absorbent pad which engages the handle .
8. The door handle according to any one of claims 1-7 in which the secondary reservoir spans substantially the full length of the handle.
9. The door handle according to any one of claims 1-8 in which the handle is substantially circular in cross section, and in which the secondary reservoir spans approximately one third of the cross-sectional circumference of the handle.
10. The door handle according to any one of claims 1-9 in which the secondary reservoir has a wiper at its downstream side.
11. The door handle according to any one of claims 1-10 in which the handle rotates through less than one complete rotation during movement of the handle from the activated position to the rest position .
12. The door handle according to any one of claims 1-11 in which the handle rotates through approximately 240° during movement of the handle from the activated position to the rest position.
13. The door handle according to any one of claims 1-12 in which the handle has a first end and a second end, and in which the mounting mechanism supports the handle at its first end and at its second end.
14. The door handle according to any one of claims 1-13 in which the handle is pivotable relative to the housing between the rest position and the activated position.
15. The door handle according to claim 14 in which the handle has a pivot axis which is substantially parallel with the longitudinal axis of the handle.
16. The door handle according to any one of claims 1-15 in which the primary reservoir is a replaceable pump action dispenser
17. The door handle according to any one of claims 1-16 in which the pump mechanism operates to drive the cleaning agent from the primary reservoir to the secondary reservoir as the handle is moving from the rest position to the activated position .
18. The door handle according to any one of claims 1-15 in which there is at least one fluid conduit for the cleaning agent connecting the primary reservoir to the secondary reservoir.
19. The door handle according to any one of claims 1-18 in which there are multiple fluid conduits for delivering the cleaning agent to the secondary reservoir, the multiple conduits being connected at spaced locations along the secondary reservoir.
20. The door handle according to claim 18 or claim 19 in which there is a manifold between the primary reservoir and the secondary reservoir.
21. The door handle according to claim 20 in which the fluid conduit(s) between the primary reservoir and the manifold is(are) substantially rigid .
22. The door handle according to claim 20 or claim 21 in which the fluid conduit(s) between the manifold and the secondary reservoir is(are) flexible.
23. The door handle according to any one of claims 20-22 in which a push rod is connected to the manifold, the push rod being driven to reciprocate as the handle moves from its rest position to its activated position and back to its rest position.
24. The door handle according to claim 23 in which the mounting mechanism includes a drive gear, a driven gear, a drive arm and the push rod, in which the drive gear rotates as the handle moves between its rest position and its activated position, and in which the driven gear meshes with the drive gear, the drive arm is connected to the driven gear and the push rod is connected to the drive arm.
25. The door handle according to any one of claims 1-24 in which the rotation mechanism includes a pinion connected to a drive shaft, the drive shaft engaging the handle.
26. The door handle according to claim 25 in which the pinion meshes with a fixed gear segment, movement of the handle between its rest and activated positions rotating the pinion and the drive shaft.
27. The door handle according to claim 25 or claim 26 in which the rotation mechanism also includes a rotation shaft, the rotation shaft engaging the handle .
28. The door handle according to claim 27 in which the drive shaft and the rotation shaft are both substantially coaxial with the longitudinal axis of the handle.
29. The door handle according to claim 27 or claim 28 in which opposing ends of the handle are supported by the drive shaft and the rotation shaft respectively.
30. The door handle according to any one of claims 27-29 in which a first one way rotation element is mounted to the drive shaft and a second one-way rotation element is mounted to the rotation shaft, in which the first one-way rotation element allows rotation of the drive shaft relative to the handle as the handle moves from its rest position to its activated position and substantially prevents rotation of the drive shaft relative to the handle as the handle moves from its activated position to its rest position, and in which the second one-way rotation element substantially prevents rotation of the handle as the handle moves from its rest position to its activated position and allows rotation of the handle as the handle moves from its activated position to its rest position.
