Pressure-fed accessories adapter for an airless spray gun

An apparatus comprising:

• a spray gun;
• a spray tip assembly;
• and
• a spray gun adapter configured to be installed in a bore of the spray tip assembly of the spray gun in place of a spray tip, the spray tip assembly also having a connector which releasably attaches the spray tip assembly to the spray gun, the spray gun adapter establishing fluid communication between an outlet of a fluid pump of the spray gun and a paint roller connected to a tube, wherein the spray gun adapter, when installed in the bore of the spray tip assembly and connected to an end of the tube, provides a flow path that directs fluid from the spray gun through the adapter and through the tube to the paint roller for paint application, wherein the spray gun adapter includes an adapter body having an adapter inlet, an adapter outlet, and a bore that extends within the adapter body from the adapter inlet to the adapter outlet, and wherein the spray gun adapter is configured to be installed in the bore of the spray tip assembly by removing the spray tip from the bore of the spray tip assembly and installing the spray gun adapter into the bore of the spray tip assembly without removing the spray tip assembly from the spray gun.

An apparatus comprising:

• a spray gun;
• a spray tip assembly attached to the spray gun and having a bore for receiving and holding a spray tip;
• and
• a spray gun adapter configured to be installed in the bore of the spray tip assembly of the spray gun in place of the spray tip, the spray gun adapter establishing fluid communication between a fluid pump of the spray gun and a tube connected to an applicator accessory, wherein the spray gun adapter is configured to engage the spray tip assembly so that, when a cylindrical portion of the spray gun adapter is installed in the bore of the spray tip assembly and a coupler is connected between the spray gun adapter and the tube, a flow path is established that directs fluid from the spray gun through the spray gun adapter, to the tube connected to the applicator accessory for paint application, so that fluid communication is established between the spray gun and the applicator accessory, wherein the spray gun adapter includes an adapter body having an adapter inlet, an adapter outlet, and an adapter bore that extends within the adapter body from the adapter inlet to the adapter outlet, and wherein the spray gun adapter is configured to be installed in the bore of the spray tip assembly by removing the spray tip from the bore of the spray tip assembly and installing the spray gun adapter into the bore of the spray tip assembly without removing the spray tip assembly from the spray gun.

An apparatus for supplying paint under pressure to a paint applicator, the apparatus comprising:

• a spray gun comprising:
• a housing;
• a fluid pump having an outlet disposed within the housing;
• and
• a spray tip assembly fluidly connected to the outlet of the fluid pump at a rear end of the spray tip assembly and having a bore in a side of the spray tip assembly configured for receiving and holding a spray tip so that an inlet of the spray tip is aligned with and in fluid communication with the outlet of the fluid pump, and a front end of the spray tip assembly, wherein when the spray tip is aligned with and in fluid communication with the outlet of the fluid pump and the fluid pump is activated, paint is atomized and flows out the front end of the spray tip assembly;
• and
• a spray gun adapter configured to be installed in the bore of the spray tip assembly in place of the spray tip, the spray gun adapter comprising:
• an adapter body having a first portion configured to fit in the bore of the spray tip assembly and a second portion configured to extend out of the bore of the spray tip assembly;
• an adapter inlet configured to be aligned with and in fluid communication with the outlet of the fluid pump when the first portion of the adapter body is located in the bore;
• an adapter outlet in fluid communication with the adapter inlet, so that when the first portion of the adapter body is located in the bore and the fluid pump is activated, fluid flow is established from the fluid pump of the spray gun through the adapter inlet, through the adapter outlet, and thereby through the adapter body and the spray gun adapter, and to an applicator accessory connected to the adapter outlet;
• and
• an adapter bore within the adapter body that connects the adapter inlet and the adapter outlet;
• wherein the spray gun adapter is configured to be installed in the bore of the spray tip assembly by removing the spray tip from the bore of the spray tip assembly and installing the spray gun adapter into the bore of the spray tip assembly without removing the spray tip assembly from the spray gun.

A method for dispensing paint from an application accessory using a spray gun, the method comprising:

• removing by hand a spray tip from a bore in a side of a spray tip assembly without disconnecting the spray tip assembly from the spray gun, the spray tip assembly connected to an outlet of a fluid pump within the spray gun;
• installing a spray gun adapter in the bore of spray tip assembly by hand so that the spray gun adapter is in fluid communication with the outlet of the fluid pump;
• connecting tubing between an applicator accessory and the spray gun adapter;
• and
• dispensing fluid from the spray gun, through the spray gun adapter and the tube to the applicator accessory to dispense paint from the applicator accessory:
• wherein the spray gun adapter includes an adapter body having an adapter inlet, an adapter outlet, and a bore that extends within the adapter body from the adapter inlet to the adapter outlet;
• and
• wherein the spray gun adapter is configured to be installed in the bore of the spray tip assembly by removing the spray tip from the bore of the spray tip assembly and installing the spray gun adapter into the bore of the spray tip assembly without removing the spray tip assembly from the spray gun.
