Pressure-fed accessories adapter for an airless spray gun

An apparatus comprising:

• a handheld airless spray gun;
• and
• a spray gun adapter configured to be installed in an unthreaded spray tip bore of a spray tip assembly of the handheld airless spray gun in place of a spray tip for establishing fluid communication between an outlet of a fluid pump of the handheld airless spray gun and a paint roller connected to a tube, the spray gun adapter comprising:
• an adapter body having a cylindrical lower portion having a sidewall with an unthreaded exterior surface configured to fit in the unthreaded spray tip bore of the spray tip assembly and an upper portion configured to extend out of the spray tip bore;
• an adapter bore that extends axially from the upper portion downward into the cylindrical lower portion of the adapter body;
• and
• an adapter inlet that extends radially inward from the sidewall of the cylindrical lower portion of the adapter body and intersects the adapter bore, the adapter inlet configured to be in fluid communication with the outlet of the fluid pump when the cylindrical lower portion of adapter body is located in the spray tip bore;
• an adapter outlet in fluid communication with the adapter inlet via the adapter bore, the adapter outlet located at the upper portion of the adapter;
• and
• a cavity located within the upper portion and extending between the adapter outlet and an upper end of the adapter bore and fluidly connecting the adapter outlet to the adapter bore, wherein the adapter outlet, the cavity, and the adapter bore are axially aligned, and wherein the adapter outlet and the cavity are of larger diameter than the adapter bore and are configured to receive a coupler for connecting the adapter to the tube;
• wherein the adapter, when installed in the unthreaded bore of the spray tip assembly and connected to an end of the tube, provides a flow path that directs fluid from the handheld airless spray gun through the adapter and through the tube to the paint roller for paint application.

An apparatus comprising:

• a handheld airless spray gun;
• and
• a spray gun adapter configured to be installed in an unthreaded bore of a spray tip assembly of the handheld airless spray gun in place of a spray tip, for establishing fluid communication between a fluid pump of the handheld airless spray gun and a tube connected to an applicator accessory, the spray gun adapter comprising:
• an adapter body upper portion that includes a head containing a cavity, an adapter outlet at an upper end of the cavity, and an outward extending handle;
• an adapter body cylindrical lower portion having a sidewall with an unthreaded exterior surface configured to be installed in the unthreaded bore of the spray tip assembly;
• an adapter bore that extends axially into the cylindrical lower portion of the adapter body;
• and
• an adapter inlet that extends radially inward from the sidewall of the cylindrical lower portion and intersects the adapter bore;
• a coupler having a first end insertable into the cavity through the adapter outlet and a second end configured to make a connection to the tube connected to the applicator accessory;
• and
• wherein the adapter outlet is in fluid communication with an upper end of the adapter bore, wherein the adapter outlet, the cavity, and the adapter bore, and the adapter inlet form a flow path between the handheld airless spray gun and the coupler;
• and
• wherein the adapter is configured to engage the spray tip assembly so that, when the cylindrical lower portion is installed in the unthreaded bore of the spray tip assembly and the coupler is connected to the tube, a flow path is established that directs fluid from the handheld airless spray gun through the adapter to the tube connected to the applicator accessory for paint application, so that fluid communication is established between the handheld airless spray gun and the applicator accessory.
