Connection device for simultaneously connecting a series of circuits

Claim 1

In a connection device for simultaneously connecting multiple fluid circuits, the connection device having first and second interfitting support pieces carrying mating male and female elements operative to connect said fluid circuits, and the support pieces being maintained in mating position by lock means passing through bore in the pieces, the lock means comprising: a cylindrical twist lock extending through the bore in the first support piece, the twist lock having a head at one end and having pin means extending transversely across the twist lock near the other end and maintaining the twist lock in the bore with its other end extending toward the second support piece, the first support piece having recesses positioned to receive said pin means, and spring means around the twist lock between its head and the first support piece and yieldably urging the pin means into engagement with the recesses when the twist lock is in a predetermined angular orientation; and a bushing fixed in the bore through the second support piece, the bushing having an opening to pass the twist lock therethrough and the opening having notches located laterally thereof and extending parallel to the opening to pass the pin means through the bushing when the twist lock enters the opening with said predetermined angular orientation, and the bushing having ramps extending from the notches away from the first support piece when mated and terminating in recesses positioned to receive and retain the pin means when the twist lock is inserted through the opening and rotated so that the pin means ride up the ramps into their recesses to compress the spring means.
