Patent ID: 7661606

Claim:
An automated spraygun to spray/atomize a product, said spraygun comprising: a spraygun body that includes several first feed conduits for feeding the product to be sprayed and a pressurized gas, and a rest face into which said first feed conduits issue in the form of first orifices; a foundation including a seating face against which said rest face is forced, and several second feed conduits that are complementary to said first feed conduits and terminate, on one hand, into connection elements to product and pressurized gas feeds and, on the other hand, into second orifices in said seating face, said first and second orifices being configured in a manner that each of the first orifices coincides with a respective one of the second orifices when said rest face of the spraygun body is forced against said seating face of the foundation; seals to be inserted between said seating face and said rest face and peripherally located at each junction between the respective first and second orifices; and assembly and locking means for allowing quick assembly and locking of said spraygun body to said foundation; wherein said assembly and locking means comprise: positioning means for positioning said spraygun body on said seating face and adapted to project perpendicularly from one of said rest and seating faces and to translate orthogonally into the other of said rest and seating faces in a manner to position said rest face relative to said foundation face in their plane; a locking stub projecting perpendicularly from one of said rest and seating faces and orthogonally translating into the other of said rest and seating faces; and quick locking means for applying an axial pull on said locking stub to keep said rest and seating faces forced against each other; wherein said locking means for said locking stub are rotatably mounted about an axis which is substantially perpendicular to said stub and are adapted to convert their rotation about the axis to an axial pull motion of said locking stub; and said locking means include a barrel having an axial cavity that runs parallel to its axis, a radial cavity intersecting with the axial cavity and exhibiting a width larger than that of a head of said locking stub, and a slot which is transverse to said barrel, which communicates with said axial and radial cavities, and which exhibits a width larger than that of a rod of said locking stub but less than that of the head of said locking stub.
