Side-mounted automatic power release attachment for manual connectors

Claim 2

A side-mounted release adapter for a conventional, manually operable, quick-release connector having interconnectible male and female fittings, and a rotatable shaft mounted in said female fitting and extending transverse to a prong on said male fitting for releasably locking said fittings together, said female fittings having a side opening through which an end of said rotatable shaft is accessible; said adapter comprising: a housing; means for detachably mounting said housing to the side of the female fitting adjacent said side opening so that the adapter can be readily removed fom the fitting; said housing having a cylinder; a piston slidably mounted in the cylinder in a direction normal to said rotatable shaft; fluid power source means in said cylinder for driving the piston; rotatable driving means mounted in said housing for interconnecting said rotatable shaft with said piston; said driving means being readily separable in an axial direction when the housing is detached; said adapter having means for securing the rotatable shaft in a released position preventing reuse of the connector; whereby activation of the power source will cause the piston through said rotatable means to rotate the shaft and release said fittings.

Claim 3

The power adapter of claim 1 wherein said fluid source is self-contained, and said securing means prevents the connector to be reusable until the spent adapter is replaced with a new power source.

Claim 4

The power adapter of claim 2 wherein the end of an extension of the rotatable shaft and said rotatable driving means have interconnecting complementary lug and recess surfaces to enable an expended power adapter to be readily replaced from a position laterally the connector.

Claim 5

The power adapter of claim 3 wherein said lug is mounted on the end of the extension of said rotatable shaft, and said recess is formed on the rotatable means.

Claim 6

The power adapter of claim 1 wherein said rotatable means is a disk-shaped member having an offset cam surface formed in an end face thereof engageable by the piston.

Claim 7

The power adapter of claim 5 wherein said cam surface leads to a socket, and said piston has an extending rod capable of being seated in said socket.

Claim 8

The power adapter of claim 1 wherein said housing has an opening co-extensive with said side opening in the female fitting when attached thereto, and extending transverse to the cylinder; said rotatable means being a disk-shaped anvil member rotatably mounted in said housing opening; said disk having an off-set cam surface; said piston having a rod extension aligned with the cam surface for rotating the disk; said disk having a socket adjacent said cam surface to receive the piston extension for securing the parts together in a locked condition after the disk has been rotated; the rotatable shaft end and disk having interconnectible lug and recess surfaces.

Claim 9

A quick-release connector comprising: a male connector half fitting having at least one longitudinally extending prong having a recess at its free end; a female connector half fitting having at least one longitudinal opening to receive said prong; a shaft rotatably mounted transversely in said female fitting and engageable with the recess in said prong for releasably locking together said connector fittings; said female fitting having a side opening through which an end of said rotatable shaft is accessible; manual lever means for actuating the rotatable shaft to disengage said prong to permit the fittings to be separated; said connector having a housing on one side of the female fitting provided with a transverse opening adjacent to and aligned with said side opening in the female fitting; said housing having a cylinder; a piston slidably mounted in the cylinder in a direction normal to said side opening; a fluid power source for driving the piston; a driving member rotatably mounted in said housing adjacent to said side opening and connected to the end of said rotatable shaft; said driving member being aligned with the piston and engageable thereby for rotation; whereby activation of the power source will cause the piston through said driving member to rotate the shaft and unlock said fittings; said driving member having means for securing the rotatable shaft and the connector in the unlocked position.

Claim 10

A quick-release connector comprising: a male connector half fitting having at least one longitudinally extending prong having a recess at its free end; a female connector half fitting having at least one longitudinal opening to receive said prong; a shaft rotatably mounted transversely in said female fitting and engageable with the recess in said prong for releasably locking together said connector fittings; said female fitting having a side opening through which an end of said rotatable shaft is accessible; manual lever means for actuating the rotatable shaft to disengage said prong to permit the fittings to be separated; said connector having a housing on one side of the female fitting provided with a transverse opening adjacent to and aligned with said side opening in the female fitting; said housing having a cylinder; a piston slidably mounted in the cylinder in a direction normal to said side opening; a fluid power source for driving the piston; a driving member rotatably mounted in said housing adjacent to said side opening and connected to the end of said rotatable shaft; said driving member being aligned with the piston and engageable thereby for rotation; whereby activation of the power source will cause the piston through said driving member to rotate the shaft and unlock said fittings; said driving member having means for securing the rotatable shaft and the connector in the unlocked position.
