ABSTRACT:
FIELD OF THE INVENTION
This invention relates to hand tools. Specifically this invention relates to a hand tool particularly wherein a high number of hand tool functions are provided in one hand tool.
BACKGROUND OF THE INVENTION
The hand tool art traditionally provided tool sets, such as screwdriver sets and socket wrench sets. These sets were comprised of multiple hand tools to accomplish different tool bit drive functions as well as to accomplish differently sized similar tool bit drive functions.
Prior art commercial screwdriver sets would, by way of example, include from eight (8) to twenty-two (22) screwdrivers or separately housed tool bit drives, as shown in attached
FIGS. 1 and 2
, respectively. Socket wrench sets and tool bit drive sets required specialized mounting and storage for the large pluralities of socket drives and tool bit drives.
The art desired multiple tool bit drive combination tools to reduce the mounting and storage requirements. Rocca, U.S. Pat. No. 4,448,097 granted May 15, 1994, disclosed a complex multiple piece housing construction which provided a total of six (6) tool bit drive functions and two (2) nut drive means functions. Kozak, U.S. Pat. No. 5,450,775 granted Sep. 19, 1995, disclosed a multiple tool bit drive function of complex housing design. These early attempts achieved some limited multiple functionality in a hand tool, and required complex construction. The hand tool art however ultimately desired a single hand tool which contained essentially an entire or complete screwdriver set or tool bit drive hand tool set. The prior art fell far short of that need.
SUMMARY OF THE INVENTION
This invention in one broad aspect is a single hand tool which operably contains a complete screwdriver or multiple tool bit drive hand tool set. In another aspect, this invention is one hand tool which integrally contains upwards of 26 different tool bit drives in combination with multiple hex nut drives, which tool bit drives and hex nut drives are readily interchangeably used in the one hand tool.
The hand tool of the present invention provides an ergonomic handle design to house a maximized number of tool bit drives and hex nut drives. The handle in combination with a removable multiple tool bit drive shank provides a full complement of tool bit drives.
In another aspect, the present invention provides, in further combination with the aforesaid, a clear plastic ergonomic handle which permits ready viewing of and access to the tool bit drives within the handle. The tool bits may be color coded as to both size and function for viewing through the clear plastic handle for ready identification and access.
The hand tool of the present invention provides essentially a complete tool set to the user. The hand tool is of practical and safe design and construction, and readily manufactured by means known to those skilled in the art.
