Abstract

A connecting device for connecting two or more components to one another, includes an inlet section and an outlet section. The inlet section and the outlet section respectively include one or more connectors for each of the two or more components, with one or more passages extending between the inlet section and the outlet section, with the connecting device being of single piece design and being plastic.

First claim

What is claimed is:

1. A spray mixer comprising:
a cartridge filled with a one-component or multi-component material having one or more outlets;
a mixer attached to the outlets of the cartridge;
a spray nozzle connected either directly to the outlet of the cartridge or to the outlet of the mixer; and
a connecting device for connecting the spray nozzle and a component to one another, the connecting device connected to the spray nozzle for the supply of a gas, the connecting device comprising an inlet section with a first connector for the component, an outlet section with a second connector for the spray nozzle, with one or more passages extending between the inlet section and the outlet section, with the connecting device being of single piece design and being plastic, and the second connector being a movable quick release mechanism integrally formed at the outlet section, the movable quick release mechanism including a flexible arm having a proximal end connected to the outlet section and a distal end free of the outlet section, and a locking protrusion disposed on the distal end of the flexible arm.

2. The spray mixer in accordance with claim 1 , wherein the connecting device is an elbow and the component is a hose and the connecting device is configured to connect the hose to the spray.

3. The spray mixer in accordance with claim 1 , wherein the first connector of the connecting device is a hose connector arranged at an end of the connecting device and the movable quick release mechanism is a nozzle connector at the other end of the connecting device with a passage extending from the hose connector to the nozzle connector.

4. The spray mixer according to claim 3 , wherein the hose connector is a hose barb.

5. The spray mixer according to claim 3 , wherein the flexible arm of the nozzle connector is one of a wing of one, two or more wings configured to actuate the locking protrusion of the nozzle connector.

6. The spray mixer according to claim 5 , wherein the one, two or more wings are each coupled to the locking protrusion and movement of a respective wing induces a radial movement of the locking protrusion to actuate a retaining or releasing function of the nozzle connector.

7. The spray mixer according to claim 5 , wherein the one, two or more wings are spring loaded with respect to a body of the connecting device.

8. The spray mixer according to claim 3 , wherein the hose connector comprises one, two or more projections projecting radially toward the passage.

9. The spray mixer according claim 3 , further comprising a seal arranged at the nozzle connector.

10. The spray mixer according to claim 3 , wherein the hose connector is arranged at an angle selected in the range of 30° to 60° with respect to the nozzle connector.

11. The spray mixer according to claim 1 , wherein the connecting device is a 3D printed elbow.

12. The spray mixer according to claim 1 , wherein the connecting device is configured to conduct pressurized gas.

13. The spray mixer according to claim 1 , wherein the connecting device is an elbow configured to be coupled to the spray nozzle for the supply of gas in order to spray fluid components exiting a cartridge either directly or multi-component materials mixed by way of a mixing element.

14. The spray mixer according to claim 1 , wherein the movable quick release mechanism is a single outlet connector, and one passage extends between the inlet section and the outlet section.

15. The spray mixer according to claim 1 , wherein movable quick release mechanism is a single outlet connector, and two or more passages extend between the inlet section and the outlet section.

16. The spray mixer according to claim 1 , wherein the first connector is one of two or more inlet connectors, the movable quick release mechanism is a single outlet connector, and two or more passages extends between the inlet section and the outlet section.
