Abstract

A masking system and method for painting a vehicle with parts made of dissimilar materials is provided. The masking system includes a masking gasket temporarily mounted between a mounting surface of a first part and a mounting surface of a second part. The masking gasket further includes a plurality of links, thermal expansion joints linking together the plurality of links, and mounting locations for securing the masking gasket to the first and second parts of the vehicle.

First claim

What is claimed is:

1. A masking system for painting a vehicle with a vehicle roof panel made of a first material and an outer side panel made of a second material, comprising:
a masking gasket temporarily mounted between a first mounting surface of the vehicle roof panel and a second mounting surface of the outer side panel, further comprising:
a plurality of links, each of the plurality of links having a male end and a female end;
thermal expansion joints linking together the plurality of links formed by the male end of each of the plurality of links attached to the female end of an adjacent one of the plurality of links, the plurality of links forming a closed chain; and
mounting locations for securing the masking gasket to the vehicle roof panel and the outer side panel of the vehicle.

2. The masking system of claim 1 wherein the first material comprises aluminum and the second material comprises steel.

3. The masking system of claim 1 wherein the thermal expansion joints are configured to accommodate the expansion rates of the first and second materials and the masking gasket when the vehicle is heated during a painting process.

4. The masking system of claim 1 wherein the links are shaped so that a first side is contoured to match the first mounting surface of the vehicle roof panel and that a second side is contoured to match the second mounting surface of the outer side panel.

5. The masking system of claim 4 wherein at least one of the plurality of links further comprise at least one rib along at least one of the first or second sides to absorb a tolerance in the vehicle roof panel or the outer side panel.

6. The masking system of claim 1 wherein the mounting locations of the masking gasket correspond to studs and holes in the vehicle roof panel and the outer side panel to securely attach the masking gasket between the vehicle roof panel and the outer side panel of the vehicle.

7. The masking system of claim 1 wherein the masking gasket is injection molded plastic.

8. A method of painting a vehicle having a first part made of a first material and a second part made of a second material during production, comprising the steps of:
mounting a masking gasket between a first mounting surface of the first part and a second mounting surface of the second part, the masking gasket having a plurality of links, each of the plurality of links having a male end and a female end, thermal expansion joints linking together the plurality of links formed by the male end of each of the plurality of links attached to the female end of an adjacent one of the plurality of links, the plurality of links forming a closed chain, and mounting locations for securing the masking gasket to the first and second parts of the vehicle;
aligning the second part to the masking gasket and the first part by aligning the mounting locations with a plurality of studs and holes in the first and second parts;
securably mounting the second part, the masking gasket and the first part together;
painting the vehicle with paint;
heating the vehicle in an oven to cure the paint;
unmounting the second part from the vehicle;
removing the masking gasket; and
securably mounting the second part to the first part.

9. A masking system for painting a vehicle with a first part made of a first material and a second part made of a second material, comprising:
a masking gasket temporarily mounted between a first mounting surface of the first part and a second mounting surface of the second part, further comprising:
a plurality of links, each of the plurality of links having a male end and a female end, each of the plurality of links being shaped so that a first side is contoured to match the first mounting surface of the first part and that a second side is contoured to match the second mounting surface of the second part, and at least one of the plurality of links further comprises at least one rib along at least one of the first or second sides to absorb a tolerance in the first or second part;
thermal expansion joints linking together the plurality of links formed by the male end of each of the plurality of links attached to the female end of an adjacent one of the plurality of links, the plurality of links forming a closed chain; and
mounting locations for securing the masking gasket to the first and second parts of the vehicle.

10. The masking system of claim 9 wherein the mounting locations of the masking gasket correspond to studs and holes in the first and second parts to securely attach the masking gasket between the first and second parts of the vehicle.

11. The masking system of claim 9 wherein the masking gasket is injection molded plastic.

12. The masking system of claim 9 wherein the first part comprises a vehicle roof panel and the second part comprises an outer side panel adjacent the vehicle roof panel.

13. The masking system of claim 9 wherein the first material comprises aluminum and the second material comprises steel.

14. The masking system of claim 9 wherein the thermal expansion joints are configured to accommodate the expansion rates of the first and second materials and the masking gasket when the vehicle is heated during a painting process.
