Abstract

Abstract A hand tool such as a socket wrench has a handle with integral means at one end to selectively mount any of a plurality of interchangeable tool elements in the form of socket wrench sockets. Longitudinally extending pockets about the periphery of the handle store extra sockets, and each socket is releasably retained in a pocket and may be removed therefrom by digital manipulation.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 268 words
In a hand tool which has a generally cylindrical handle provided with a bore, and mounting means to selectively mount any of a plurality of interchangeable tool elements, said mounting means including a shank non-rotatably mounted in said bore in the handle, and means at the end of the shank remote from the handle to operatively receive one of said tool elements at a time, the improvement comprising: the interchangeable tool elements are socket wrench socket elements each of which is cylindrical with a first end portion having an axially extending square drive hole and a second end portion having an axially extending hexagonal socket, said socket elements being of various diameters, all of said drive holes being identical with one another, and all of said hexagonal sockets being of different sizes each of which is adapted to slidably and non-rotatably engage a hexagonal fastener of a predetermined size; the means to operatively receive said tool elements is a socket wrench ratchet drive with a square mounting stub which projects laterally from the shank and slidably engages in a square drive hole of a socket element; and the handle has a plurality of longitudinally extending pockets about its periphery for storing all said socket elements, said plurality of pockets being arranged in sets of two pockets which are end-to-end, there is a partition separating the two pockets of each set, and the pockets are of various diameters each of which snugly receives and stores a particular one of the socket elements, each socket element being individually removable by digital manipulation from the pocket in which it is stored.
Claim 2
Dependent Claim 268 words
In a hand tool which has a generally cylindrical handle provided with a bore, and mounting means to selectively mount any of a plurality of interchangeable tool elements, said mounting means including a shank non-rotatably mounted in said bore in the handle, and means at the end of the shank remote from the handle to operatively receive one of said tool elements at a time, the improvement comprising: the interchangeable tool elements are socket wrench socket elements each of which is cylindrical with a first end portion having an axially extending square drive hole and a second end portion having an axially extending hexagonal socket, said socket elements being of various diameters, all of said drive holes being identical with one another, and all of said hexagonal sockets being of different sizes each of which is adapted to slidably and non-rotatably engage a hexagonal fastener of a predetermined size; the means to operatively receive said tool elements is a socket wrench ratchet drive with a square mounting stub which projects laterally from the shank and slidably engages in a square drive hole of a socket element; and the handle has a plurality of longitudinally extending pockets about its periphery for storing all said socket elements, said plurality of pockets being arranged in sets of two pockets which are end-to-end, there is a partition separating the two pockets of each set, and the pockets are of various diameters each of which snugly receives and stores a particular one of the socket elements, each socket element being individually removable by digital manipulation from the pocket in which it is stored.
Claim 3
Dependent Claim 32 words
The improvement of claim 1 in which the height and thickness of each partition facilitates digital manipulation of the socket elements stored in the two pockets which are separated by said partition.
Claim 4
Dependent Claim 62 words
The improvement of claim 1 or claim 2 which includes a single pocket in the handle that is substantially as long as the two pockets in a set, and an extension element that has a square hole at one end and a square mounting stub at the other end, and said extension element is snugly received and stored in said single pocket.
Claim 5
Dependent Claim 68 words
The improvement of claim 1 or claim 2 in which the bore is cylindrical and extends entirely through the handle, the shank of the mounting means is slidable received in and extends substantially entirely through said bore, interengaging parts of the handle and the shank prevent relative rotation between them, and movable means mounted on the handle engages the shank to releasably fix the shank in the bore.
Claim 6
Dependent Claim 40 words
The improvement of claim 4 in which the movable means on the handle comprises a spring, there is a peripheral groove in the shank, and the spring is normally engaged in the groove and is released therefrom by digital manipulation.
