Conversion adapter for a fluid supply assembly
View Patent ↗A conversion adapter for connecting a fluid supply assembly to a fluid applicator. The conversion adapter provides a connection between the fluid supply assembly and the fluid applicator. The conversion adapter has a first end and a second end, and a bore between the first end and the second end. The first end has a complementary connecting surface mating with the connecting surface on the fluid supply assembly. The second end has a complementary connector in the bore, and a top and bottom. The complementary connector is selected from complementary grooves or complementary projections, and mates with the connector on the adapter of the fluid applicator.
1. A combination of a fluid supply assembly and a fluid applicator, comprising:
the fluid applicator comprising a spray gun having an adapter with a connector on an outer surface, the connector being at least one groove formed in the outer surface;
the fluid supply assembly comprising a cup and a lid covering an opening in the cup, the fluid supply assembly having a connecting surface; and
a conversion adapter having a first end and a second end, and a bore between the first end and the second end, the bore having a surface, the first end having a complementary connecting surface mating with the connecting surface on the fluid supply assembly, the second end having a complementary connector in the bore, the second end having a top and bottom, the complementary connector being at least one complementary projection, the complementary connector mating with the connector on the adapter of the fluid applicator, wherein the complementary projection engages the groove to secure the conversion adapter to the adapter of the fluid applicator.
2. The combination of claim 1 wherein the groove extends from a bottom of a second end of the adapter of the fluid applicator toward the top.
3. The combination of claim 1 wherein the groove forms a helix.
4. The combination of claim 1 wherein the groove is formed at a first angle from a plane of a bottom of a second end of the adapter of the fluid applicator.
5. The combination of claim 1 wherein the groove has a second portion near a top of a second end of the adapter of the fluid applicator, the second portion extending at a second angle from a plane of the groove.
6. The combination of claim 5 wherein the second portion of the groove extends parallel to a plane of a bottom of a second end of the adapter of the fluid applicator.
7. The combination of claim 1 wherein the complementary projection is positioned below the top of the second end of the conversion adapter.
8. The combination of claim 1 wherein a portion of the bottom of the conversion adapter is smaller than a bottom of the adapter of the fluid applicator to provide an interference fit with the conversion adapter.
9. The combination of claim 1 wherein the first end or the second end is generally cylindrical.
