Abstract:
An assembly for connecting a liquid supply to an inlet port on a gravity fed liquid spraying device, said assembly comprising:a first adapter having first and second end portions and a through opening extending through said end portions, said first end portion of said first adapter including means for communicating with the liquid supply; a second adapter having first and second end portions, and a through opening extending through said end portions of said second adapter, said first end portion of said second adapter including means for engaging the inlet port of the gravity feed spray gun; the second end portions of the adapters having connector parts adapted for releasable liquid tight engagement with the through openings in the adapters in communication; said connector parts on said first adapter including a projecting portion having an outer surface and axially spaced proximal and distal ends, and projecting resiliently flexible hook members on opposite sides of the projecting portion, said hook members having distal ends and opposed radially inwardly projecting lips on said distal ends; and said connector parts on said second adapter including an inner surface in the second end portion of the second adapter defining a bore opening through the end of the second adapter and adapted to receive the projecting portion of the of the first adapter in an engaged position with the outer surface of the projecting portion in liquid tight engagement with the inner surface, and a collar around the second end portion of the second adapter, said collar having major recesses along opposite sides adapted to pass the distal ends of the projecting hook members of the first adapter when the projecting portion is pressed axially into the bore with the first and second adapters in a first relative position at which the hook members are aligned with the major recesses in the collar, said collar having retaining surfaces facing the first end of the second adapter extending along corresponding sides of said major recesses, and said first and second adapters being rotatable relative to each other to a second relative position when said adapters are in said first relative position to cause the lips on hook members to be engaged with said retaining surfaces on the collar, said collar including cam lobes projecting radially outwardly on corresponding sides of the major recesses, and minor recesses in the collar on the sides of the cams opposite the major recesses, said retaining surfaces extending along said second recesses, and rotation of said first and second adapters to said second relative position causing the resiliently flexible projecting hook members to be deflected radially outwardly by, and to move around said cam lobes until the projecting hook members are positioned in said minor recesses in the collar at which position said Inwardly projecting lips on the distal ends of the projecting book members are engaged with said retaining surfaces of the collar.
