Abstract

A concealed and built-up type multipurpose hand tool structure which includes a hollow and T-shaped handle for storing a variety of sockets, having middle through-holes to receive therein a variety of hexagonal wrenches or driver heads or other cylindrical tool parts.

Claims

1. A multi-purpose hand tool structure comprising:

(a) a hollow handle portion for storing a plurality of sockets therein;

(b) a plurality of sockets for storage within the hollow handle portion;

(c) a socket connector

(d) each socket including a first hole at one end thereof for engagement with said socket connector, a second hole at another end thereof for engaging a fastener head, and a middle through hole extending between the first and second holes, each middle through hole having an inner diameter sized to receive a cylindrical tool part therein;

(e) a cylindrical tool part disposable within the middle through hole of each socket, wherein the sockets and their corresponding tool parts may collectively be stored within the hollow handle portion; and

(f) engaging means for detachably selectively securing said socket connector or one of said tool parts to the tool structure.

2. The tool structure of claim 1 wherein each socket and tool part are dimensioned so that only a single tool part is receivable in each socket.

3. The tool structure of claim 1 wherein the middle through hole of each socket has an inner diameter that is slightly larger than the largest outer diameter of any of the tool parts, so that any tool part may be received in the middle through hole of any socket.

4. The tool structure of claim 1 wherein the middle through hole of each socket is of a substantially round configuration, the first and second holes being each of a hexagonal configuration, and the middle through hole communicating with the first and second holes.

5. The tool structure of claim 1 wherein the handle portion is of a substantially T-shaped configuration and including a hollow horizontal leg for storing the sockets and tool parts and a vertical leg including a lower end, said engaging means located at said lower end.

6. The tool structure of claim 5 wherein the lower end includes an outer passageway and an inner passageway, the outer passageway having an inner diameter that is larger than the inner diameter of the inner passageway, and the detachable engaging means includes a steel ball extending through the wall of the lower end into the outer passageway and a C-ring surrounding the lower end for maintaining the ball in position.
