Abstract
Abstract A socket wrench extension for effecting a quick release and simultaneous removal of a socket. The extension has a shaft with an attachment located at one end of the shaft adapted to connect to the socket wrench drive and a stud located at the other end for connecting to the socket. A sleeve is rotatably and slideably mounted on the shaft for moving a detent between a released and a locked position. The sleeve also simultaneously releases and urges the socket off the extension.

An extension for use with the drive member of a socket wrench system for positively holding a socket in place, comprising: a shaft of predetermined length; means on one end of the shaft for receiving a socket; means on the other end of the shaft for operatively attaching the extension to the drive member; means for securing the socket onto the receiving means, said means being operable between a first position for positively locking the socket to the extension member and a second position for releasing the socket from the extension member; and control means located on the shaft for operating said securing means between said locking and releasing positions, said control means includes means for urging the socket from the receiving end while simultaneously moving the securing means to its releasing position.
Claim 3
Dependent Claim
22 words
The invention of claim 1 wherein said control means is adapted to be operable by a single human hand gripping the shaft.
Claim 4
Dependent Claim
34 words
The invention of claim 1 or 2 wherein the control means is rotatably mounted on the shaft to allow for independent rotation of the shaft and the control means with respect to one another.
Claim 5
Dependent Claim
60 words
The invention of claims 1 or 2 wherein said securing means comprises: a detent located in the receiving means, said detent protruding out of said receiving means when the securing means is in the locking position so as to engage the socket and said detent residing substantially within the receiving means when the securing means is in its released position.
Claim 6
Dependent Claim
73 words
The invention of claim 4 further comprising: a slide pin mounted within the shaft and extending into the receiving means, said slide pin being movable between an advanced and retracted position, said detent resting upon the slide pin so that the advanced position of the slide pin corresponds to the released position of the securing means and the retracted position of the slide pin corresponds to the locked position of the securing means.
Claim 7
Dependent Claim
64 words
The invention of claim 5 wherein said urging means further comprises: a sleeve both slideably and rotatably mounted on the shaft, said sleeve sliding between a forward and a rearward position and engaging the slide pin such that the movement of the sleeve between its forward and rearward positions causes the corresponding movement of the slide pin between its advanced and retracted positions respectively.
Claim 8
Dependent Claim
24 words
The invention of claim 6 wherein the slide pin is biased to its retracted position and the sleeve is biased to its rearward position.
