Applicator pad for use with an apparatus for applying a fluid to the tires of a vehicle
A vehicle tire dressing apparatus according to the present invention comprises left and right dressing applicators situated alongside a vehicle conveying track, the dressing applicators being moveable individually into contacting engagement with tires on left and right sides of a vehicle in the track. Each applicator has an applicator pad mounted to a mount bar and the mount bar is hinged to a frame which allows articulation of the applicator pad into and out of contact with the tires. The applicator pad is configured with a plurality of orifices, each of which orifices receives fluid sprayed from a complimentary spray nozzle. Each orifice has an elongated capillary which assists dispersing fluid into the pad. The spray nozzles emit fluid into the pads for a predetermined amount of time, the spraying being initiated by movement of the vehicle into proximity with the tire dressing assembly.
1. An applicator pad for use with an apparatus having a spray nozzle for applying a fluid to vehicle tires, the applicator pad comprising:
a pad body having a first portion which is porous for retaining a fluid;
a contact surface on said first portion for engaging the sidewall of a tire of a vehicle;
the pad body also having a second portion connected to said first portion, said second portion for mounting the pad body on the apparatus;
said second portion defining an orifice for receiving a portion of the spray nozzle when the applicator pad is used with the apparatus; and
said orifice being in communication with said porous first portion of the pad body and said contact surface such that fluid received in said orifice is absorbed and retained by said first portion and can be applied to the sidewall of a tire by engaging the contact surface with the sidewall of the tire.
2. The applicator pad as defined in claim 1 , wherein said second portion of the pad body is mountable and demountable on the apparatus.
3. The applicator pad as defined in claim 1 , wherein the contact surface is concave.
4. The applicator pad as defined in claim 1 , wherein the contact surface is convex.
5. The applicator pad as defined in claim 1 , wherein said first portion of the pad body is foam.
6. The applicator pad as defined in claim 5 , wherein the foam is reticulated.
7. The applicator pad as defined in claim 1 , wherein said first portion of the pad body is hydrophobic.
8. The applicator pad as defined in claim 1 , wherein said first portion of the pad body is hydrophylic.
9. The applicator pad as defined in claim 1 , wherein said orifice includes a blind bore ending short of said first portion.
10. The applicator pad as defined in claim 1 , wherein said orifice includes a blind bore extending into said first portion and ending short of said contact surface.
11. The applicator pad as defined in claim 1 , wherein said orifice further defines a capillary extending into said first portion of said pad body.
12. The applicator pad as defined in claim 1 wherein said pad body is elongated such that the contact surface is engageable with the entire sidewall of a rotating tire mounted on a vehicle, when the pad body is stationary and the vehicle is moving.
13. An elongated applicator pad for use with an apparatus having a plurality of spray nozzles for applying a fluid to vehicle tires, the applicator pad comprising:
an elongated pad body having a first portion which is porous for retaining a fluid;
a contact surface on said first portion for engaging the sidewall of a tire of a vehicle;
the pad body also having a second portion connected to said first portion, said second portion for mounting the pad body on the apparatus;
said second portion defining a plurality of orifices spaced apart along the length of said pad body, each of the orifices for receiving a portion of one of the spray nozzles; and
each said orifice defining a blind bore in communication with said porous first portion and said contact surface such that fluid received in said orifices from the spray nozzles is absorbed and retained by said first portion and can be applied to the sidewall of a tire by engaging the contact surface with the sidewall of the tire.
14. The applicator pad as defined in claim 13 , wherein said second portion is mountable and demountable on the apparatus.
15. The applicator pad as defined in claim 13 , wherein the contact surface is convex.
16. The applicator pad as defined in claim, 13 , wherein said second portion defines a plurality of apertures for mounting the pad body to the apparatus.
17. The applicator pad as defined in claim 13 , wherein said first portion of said pad body is foam.
18. The applicator pad as defined in claim 17 , wherein the foam is reticulated.
19. The applicator pad as defined in claim 13 , wherein said first portion of the pad body is hydrophobic.
20. The applicator pad as defined in claim 13 , wherein said first portion of the pad body is hydrophylic.
21. The applicator pad as defined in claim 13 wherein each said blind bore extends through said second portion and into said first portion ending short of said contact surface.
22. The applicator pad as defined in claim 13 wherein said pad body further defines lateral capillaries connecting the orifices together, the lateral capillaries for facilitating dispersion of the fluid throughout the first portion of said pad body.
