Abstract

A multipurpose folding tool (30, 280) including a pair of folding scissors (32), in which scissors blades (80, 82) are movable about pivot shafts (78), between a stowed position and a deployed position in the handles (34, 36). A rocker (94, 96) is moved by a spring (106) in the tool handle and in turn urges a scissors blade toward an open position. In one embodiment four springs (104, 106) hold the handles together with the folded scissors stowed within the handles. When the scissors and other tools are folded into their stowed positions in the handle of the multipurpose tool of the invention the tool has a smooth outside configuration allowing the tool to be carried in a pocket without causing undue wear. A handle (34 or 36) may be constructed as a sheet metal channel or a handle (282, 284, 382, 384) in two pieces at least one of which includes a perpendicular flange taking the place of a channel bottom portion so that each blade or tool bit may be accompanied by a separate spring (318, 418, 420).

Claims

1. A folding tool including a handle, comprising:

(a) a first elongate handle side having a pair of opposite ends;

(b) a second elongate handle side having a pair of opposite ends;

(c) an elongate spring located between said first and second handle sides, said spring including an anchored end and an opposite outer end;

(d) a tool blade having a base defining a pivot hole, said base being located between said first and second handle sides; and

(e) a pair of fasteners interconnecting said handle sides and holding them parallel with each other, a first one of said fasteners fastening said anchored end of said spring between said handle sides and the other of said fasteners extending through said pivot hole in said tool blade, and at least said first handle side including a flange extending longitudinally along a portion thereof and directed toward said second handle side, said flange supporting a portion of said elongate spring at a location between said anchored end and said outer end, and said outer end of said spring engaging said base of said blade.

2. The folding tool of claim 1 wherein said first handle side and said flange are an integral piece of sheet metal.

3. The folding tool of claim 1 wherein said second handle side includes a second flange extending longitudinally along a portion thereof and directed toward said first handle side, said folding tool also including a second tool blade having a base and also including a second elongate spring, said second flange supporting a portion of said second spring and said second spring having an outer end engaging said base of said second tool blade.

4. The folding tool of claim 3 wherein said handle has a pair of opposite ends and said flanges are similarly located with respect to each of said handle sides and said handle sides are located with respect to each other so that said flanges are both adjacent the same one of said opposite ends of said handle.

5. The folding tool of claim 3 wherein said handle has a pair of opposite ends and said flanges are similarly located with respect to each of said handle sides and said handle sides are located with respect to each other so that said flanges are respectively adjacent the opposite ones of said ends of said handle.

6. The folding tool of claim 3 wherein said handle has a pair of opposite ends and said flanges are symmetrically oppositely located on said first and second handle sides and said handle sides are located with respect to each other so that said flanges are both adjacent the same one of said opposite ends of said handle.

7. The folding tool of claim 3 wherein said handle has a pair of opposite ends and said flanges are symmetrically oppositely located on said first and second handle sides and said handle sides are located with respect to each other so that said flanges are respectively adjacent the opposite ones of said ends of said handle.

8. The folding tool of claim 1 wherein said base of said tool blade includes a pair of flat surfaces and said outer end of said spring presses against a respective one of said pair of flat surfaces when said tool blade is in a closed position and against the other of said flat surfaces when said tool blade is in an extended position.

9. The folding tool of claim 1 including a pair of said handles each including a respective one of a pair of tool blades, said pair of tool blades being interconnected with each other by a pivot joint, and said first and second handle sides of each of said handles being spaced apart from each other and defining a respective cavity therebetween wide enough for a respective portion of each of said interconnected pair of tool blades to be received in the cavity of each of said handles.

10. The folding tool of claim 9 wherein said second handle side of a first one of said pair of handles also includes a second flange extending longitudinally along a portion thereof and directed toward said first handle side of said one of said pair of handles, said folding tool also including a separate tool blade having a base, and also including a second elongate spring, said separate tool blade and said second elongate spring both being located in said first one of said pair of handles, with said second flange supporting a portion of said second spring and said second spring having an outer end engaging said base of said separate tool blade.

11. The folding tool of claim 10 wherein said base of said separate tool blade is located at the one of said ends of said first one of said pair of handles opposite said base of the respective of one of said pair of interconnected tool blades included in said first one of said pair of handles.

12. The folding tool of claim 9 wherein said pair of tool blades interconnected with each other by a pivot joint are respective jaws of a pair of pliers.

13. The folding tool of claim 1 wherein a portion of said spring adjacent said anchored end thereof has a shape that conforms to the shape of respective adjacent portions of said first and second handle sides thereof.

14. The folding tool of claim 1 wherein said flange has an inner surface and an outer surface and said outer end portion of said spring has a back surface aligned with said outer surface of said flange and has a shoulder defining a surface extending along said inner surface of said flange.
