Abstract

A spray gun with a gun body having a handle region and having a head which is equipped with a cartridge which has an angled, tubular region as an inlet for a material-conducting channel which runs through the cartridge and ends in an outlet region which is arranged at the front end of the head of the spray gun, wherein the inlet region of the cartridge is connected or is connectable to a storage container for the material to be sprayed, and wherein the cartridge preferably guides at least one material-conducting component of the spray gun. The cartridge is held fixedly, but releasably, on the head of the spray gun by means of a screw collar ring, wherein the screw collar ring is preferably supported on the cartridge and/or on or in the head of the spray gun by at least one mechanism.

First claim

The invention claimed is:

1. A spray gun system for delivery of a flowable material under pressure, the system comprising a spray gun and a cartridge removably attached to the spray gun so that a gas supplied to the spray gun provides gas pressure to a flowable material supplied to the cartridge resulting in delivery of the flowable material under pressure,
wherein the spray gun comprises a gun body having a handle portion, a head for receiving the cartridge, and a slot for receiving the cartridge to removably attach the cartridge to the spray gun,
wherein the cartridge comprises: a body with a material-conducting conduit running therethrough with an angled-off tubular inlet area as an inlet connectable to a container storing the flowable material, the material-conducting conduit terminating in an outlet; a collar ring fixed to the body having an outer thread for threadably receiving an air nozzle ring for securing an air nozzle to the cartridge; a bracket arranged on the tubular inlet area for supporting the cartridge when the cartridge is attached to the spray gun; and a catch hook mounted on the body of the cartridge by a film hinge, the film hinge allowing deflection of the catch hook to selectively engage and disengage with the slot on the spray gun body to removably attach the cartridge to the spray gun
an air nozzle and an air nozzle ring for securing the air nozzle to the cartridge, wherein the air nozzle ring has a threaded inner surface for threadably engaging the collar ring and wherein air nozzle ring deflects the catch hook toward the slot when the air nozzle ring is screwed on the collar ring.

2. The spray gun system according to claim 1 , wherein the catch hook has a barb engaging the slot.

3. The spray gun system according to claim 1 , further comprising an air nozzle and an air nozzle ring for securing the air nozzle to the cartridge, wherein the air nozzle ring has a threaded inner surface for threadably engaging the collar ring.

4. The spray gun system according to claim 3 , wherein the air nozzle ring reaches at least approximately up to the tubular inlet area of the cartridge when the air nozzle ring is completely screwed on the collar ring.

5. The Spray gun system according to claim 3 , wherein screwing the air nozzle ring on the collar ring creates an additional attachment of the cartridge to the spray gun.

6. The spray gun system according to claim 1 , wherein the head has two areas connected in an articulated manner to one another that can be folded apart from one another.

7. The spray gun system according to claim 1 , wherein the collar ring can be detachably connected to the spray gun via a slip-on process.

8. The spray gun system according to claim 1 , wherein the collar ring is non-detachably connected to the spray gun.

9. The spray gun system according to claim 1 , wherein the collar ring is non-detachably connected to at least one air-conducting or material-conducting part of the spray gun.

10. The spray gun system according to claim 9 , wherein the collar ring is integrally produced to the at least one air-conducting or material-conducting part of the spray gun.

11. The spray gun system according to claim 1 , further comprising an air distributor.

12. The spray gun system according to claim 1 , wherein the air distributor has several areas arranged one alongside another or one atop another, wherein at least one of the areas has at least one air hole.

13. The spray gun system according to claim 11 , further comprising an air nozzle, wherein the air distributor and the air nozzle are a one piece assembly.

14. The spray gun system of claim 1 , wherein the gun body of the spray gun includes a suspension hook and wherein an outer surface of the bracket of the body of the cartridge rests against the suspension hook when the cartridge is attached to the spray gun.

15. The spray gun system of claim 14 , wherein the tubular inlet area has a projection for engaging the container storing the flowable material.

16. The spray gun system of claim 15 , wherein the bracket has a height and the tubular inlet area has a length and wherein the height of the bracket is about half the length of the tubular inlet area.
