Multiple hand tool
US 3892149 A
Abstract
A hand tool for different sized tools such as Allen head drivers which allows for a selection of the required size on a single tool handle. The cylindrical handle is provided with a central axial socket member mounted in a central axial opening. The socket member has a hexagonal axial opening at the bottom end. A pivot ring is mounted over the bottom edge of the socket member and a plurality of pivot members are mounted on the ring. Each pivot member supports a sleeve holder in which a hexagonal base of a hand tool is positioned. Each tool base is slidable in its sleeve against the action of a coil spring in the sleeve. The cylindrical handle is provided with longitudinal grooves extending from the bottom end in alignment with the pivot members so that the tools nest in their respective grooves in the handle. When a tool size is selected, it is pivoted from its groove downwardly until the base reaches the socket opening. The tool is pulled against the action of the spring to withdraw the tool into the sleeve holder. This allows the sleeve holder to swing directly over the opening in axial alignment therewith. The tool can now be released and pushed into the opening and the hand tool is ready for use. To remove the tool, it is pulled from the socket opening against the action of the spring until it is clear of the socket member. It can now be pivoted upwardly and back into the handle groove.

United States Patent 1191 Rydberg MULTIPLE HAND TOOL [76] Inventor: Allan Rydberg, 76 Chapman Ave.,

Warwick, RI. 02886 [22] Filed: Jan. 6, 1975 [21] Appl. No.: 538,509

Primary Examiner-James L. Jones, Jr. Attorney, Agent, or Firm-Max Schwartz [57] ABSTRACT A hand tool for different sized tools such as Allen head drivers which allows for a selection of the required size on a single tool handle. The cylindrical handle is provided with a central axial socket member [451 July 1,1975

mounted in a central axial opening. The socket member has a hexagonal axial opening at the bottom end. A pivot ring is mounted over the bottom edge of the socket member and a plurality of pivot members are mounted on the ring. Each pivot member supports a sleeve holder in which a hexagonal base of a hand tool is positioned. Each tool base is slidable in its sleeve against the action of a coil spring in the sleeve. The cylindrical handle is provided with longitudinal grooves extending from the bottom end in alignment with the pivot members so that the tools nest in their respective grooves in the handle. When a tool size is selected, it is pivoted from its groove downwardly until the base reaches the socket opening. The tool is pulled against the action of the spring to withdraw the tool into the sleeve holder. This allows the sleeve holder to swing directly over the opening in axial alignment therewith. The tool can now be released and pushed into the opening and the hand tool is ready for use. To remove the tool, it is pulled from the socket opening against the action of the spring until it is clear of the socket member. It can now be pivoted upwardly and back into the handle groove.

10 Claims, 3 Drawing Figures is s MULTIPLE HAND TOOL BACKGROUND OF THE INVENTION Many factory assemblies require a plurality of screws in different sizes. Consequently, at each assembly, the worker must have a set of tools for the different sizes. Furthermore, the tools must be precise for different sized Allen or Phillips screws. Because of crowded conditions, speeded assembly operations, and human error, tools are often mislaid, borrowed, lost, etc. This makes for delays and inefficiency in the assembly operations.

SUMMARY OF THE INVENTION The present invention is designed to provide a single hand tool having a plurality of different sized driving tools mounted thereon for easy selection and rapid positioning for use. A cylindrical handle is provided with a central axial socket member having an axial hexagonal opening. A pivot ring is mounted over the bottom edge of the socket member and a plurality of pivot members are mounted on the ring. Each pivot member supports a sleeve holder in which the hexagonal base of an Allen head driving tool is positioned. Each tool base is slidable in its sleeve against the action of a coil spring. Normally, each tool is pivoted up against the handle and rests in a groove in the handle. When a tool size is selected, it is pivotally swung down so that its base approaches the socket opening. The tool is now pulled against the action of the spring into its sleeve holder. This allows the holder to swing over the opening in axial alignment therewith. The tool is now released and pushed into the hexagonal opening. The assembly is now ready for use. To remove the tool the action is reversed. The tool is pulled from the opening until it is clear of the socket, allowing it to be pivoted back toward the handle and into its groove.

DESCRIPTION OF THE DRAWING In the drawings:

FIG. 1 is a side elevation, partially broken away, of a driver embodying my present invention;

FIG. 2 is a perspective view of the driver showing the positioning of the tools; and

FIG. 3 is a perspective view, partially broken away, of one of the tool assemblies.

DESCRIPTION OF THE INVENTION The present invention provides for a set of graduated sizes of Allen head driving tools to be irremovably mounted in a single handle, provision being made for ectively positioning any of the tools in operative poeferring more in detail to the drawings, the device prises a cylindrical handle which can be of plastic, or any other suitable material. The han- 10 is provided with a central axial opening 12 extending upwardly into the handle from the bottom end. A steel socket member 14 is tightly mounted in the opening 12 with its lower end extending from the opening, FIG. 1.

The socket member I4 is provided with a central, axial, hexagonal opening 16 extending upwardly from the bottom end. The bottom end of the socket member 14 is also provided with a slot 18 extending through the wall at each corner of the hexagonal opening 16 (6 slots). A steel pivot ring 20 is fitted over the bottom end of the socket member 14 and brazed or otherwise locked in place. A pivot member 22 is pivotally mounted on the ring 20 at each slot 18, the slots permitting free pivotal movement of the pivot members 22.

An integral supporting rod or arm 24 extends from each pivot member 22 and is attached to the side, adjacent one end, of a hollow, cylindrical, sleeve holder 26. As can be seen in FIG. 3, the bottom end of each sleeve holder 26 has a restricted opening forming a shoulder 28. The device is provided with a plurality (6 shown) of Allen head driving tools 30 in graduated sizes, each tool having the required hexagonal cross section. Each tool 30 is provided with an enlarged hexagonal base portion 32. All of the base portions 32 are the same size and adapted to fit tightly into the hexagonal opening 16 in the socket member 14. Each tool 30 is provided with an intermediate annular portion 34 between the tool end 30 and the base end 32.

Each base end 32 extends into the sleeve member 26, and a coil spring 36, FIG. 3, surrounds the portion 34 with the upper end of the spring abutting the hexagonal base portion 32 and the lower end abutting the sleeve shoulder 28. A circle clip 38 extends in a groove 40 below the assembly to hold the parts together.

The outer surface of the handle 10 is provided with a plurality (6 shown) of grooves 42. As can be seen in FIG. 2, when the tools 30 are pivoted up against the handle 10, each tool will nest in its groove 42. A small, transverse groove 44 extends around the handle I0 to accommodate the clip 38.

Now viewing FIGS. 1 and 2, the handle I0 holds six Allen head driving tools in graduated sizes, each tool being tethered to the handle so that it cannot be removed or lost. The user selects the desired size and swings it away from the handle as shown in FIG. 2. The tool 30 is now pulled against the action of the spring 36 so that the hexagonal base 32 is withdrawn into the sleeve member 26. This allows the pivotal movement to continue into the position shown in FIG. I, with the sleeve member 26 and tool 30 in axial alignment with the hexagonal opening 16. The tool 30 is now released and pushed into the opening 16 into the position shown in FIG. 1. The tool is now ready for use.

To remove the tool the action is reversed. The tool 30 is pulled against the action of the spring 36 until the hexagonal end 32 leaves the opening 16 and is clear of the bottom end of the socket member 14. The sleeve member 26 and the tool therein can now be pivoted upwardly until the tool 30 nests in its groove 42.

The basic construction can also be used for other tools. For example, hand twist drills of different sizes can be used instead of the Allen head driver. Even a standard screw driver or a Phillips head screw driver can be used in this manner.

The device thus provides a simple and efficient means of mounting a set of six tools in graduated sizes on a single handle. The tools are nested out of the way, but can be readily swung into use as desired. The selection and positioning of the required size is a simple and easy operation.

Other advantages of the present invention will be readily apparent to a person skilled in the art.
