Abstract

A spray gun manufacturing method, a spray gun, a spray gun body and a cover. The method includes forming a spray gun body. In forming the spray gun body, a bearing part is formed on a side of the spray gun body, with a surface of the bearing part being lower than another surface of the side of the spray gun body, and a partial edge of the bearing part corresponding to a partial edge of the spray gun body.

First claim

What is claimed is:

1. A method of manufacturing a spray gun, comprising:
forming a spray gun body with a complete handgrip including opposed leading and trailing edge surfaces and opposed side surfaces, the complete handgrip having first external dimensions such that the complete handgrip has a first grip size for gripping by a user of the spray gun;
cutting one of the side surfaces to remove a portion of the side surface and a portion of the leading edge surface to form an incomplete handgrip having a recessed bearing surface, with an upper surface of the recessed bearing surface being lower than the side surface before cutting; and
covering the bearing surface with a cover that is shaped and dimensioned to cover the removed portion of the side surface and leading edge surface to thereby form a modified complete handgrip having second external dimensions such that the modified complete handgrip has a second grip size for gripping by a user of the spray gun;
wherein the second external dimensions are substantially the same as the first external dimensions and the second grip size is substantially the same as the first grip size.

2. The method of claim 1 , wherein the cover includes a window opening through which a display can be viewed.

3. The method of manufacturing a spray gun according to claim 2 , wherein the display is associated with a digital pressure measurement device attached to the cover.

4. The method of manufacturing a spray gun according to claim 1 , wherein the cover and the incomplete handgrip form a shadow gap therebetween.

5. The method of manufacturing a spray gun according to claim 4 , wherein the shadow gap is formed by a step part close to an edge of the cover.

6. The method of manufacturing a spray gun according to claim 1 , wherein the cover has at least one slot that is shaped and dimensioned to receive a portion of a pressure measurement device.

7. The method of manufacturing a spray gun according to claim 6 , wherein the cover has a window opening arranged adjacent to the slot.

8. The method of manufacturing a spray gun according to claim 7 , wherein the window is covered by a transparent protective plate.

9. The method of manufacturing a spray gun according to claim 1 , wherein the cover and the recessed bearing surface together form at least one mutually engaging positioning projection and corresponding hole for receiving the positioning projection.

10. The method of manufacturing a spray gun according to claim 1 , wherein one of the cover and the recessed bearing surface includes at least one positioning or retaining projection, and the other of the cover and the recessed bearing surface includes at least one corresponding hole for receiving the positioning or retaining projection.

11. The method of manufacturing a spray gun according to claim 1 , further comprising:
inserting a pressure measurement device into the incomplete handgrip and positioning the pressure measurement device onto the recessed bearing surface.

12. The method of manufacturing a spray gun according to claim 11 , wherein the pressure measurement device is electronic and includes visible indicia indicating working pressure of the spray gun, the indicia visible through an opening in the attached cover.

13. The method of manufacturing a spray gun according to claim 12 , where the cover includes a transparent window.
