Abstract

A frame member for the handle of a folding knife or multipurpose tool includes an integral flange with an integral leaf spring. Frames are shown in the form of a channel with an integral external flange extending outwardly from the top of a channel wall in a direction away from the channel. Pivot pins extending through the channel and out the channel wall carry pivoting tool blades. An integral leaf spring on the external flange bears against the base of a blade pivotably connected to the frame outside of the channel. Other tool blades are carried inside the channel and pivot about the pivot pin.

Claims

1. A handle for a folding tool comprising:

(a). a first piece of integral material defining only one integral channel, said channel including first and second opposed side walls and a channel floor defining an internal pocket, said channel further including a first external flange, integral with said first piece of integral material, extending outwardly from said first side wall in a first direction away from said channel, said first external flange including a first leaf spring also integral with said first piece of material; and

(b). a first side scale, separate from and not an integral part of said first piece of integral material, said first side scale secured to said channel adjacent to said first external flange such that said first side wall, said first external flange and said first side scale define a first external pocket.

2. The handle of claim 1 wherein said first piece of integral material is sheet metal.

3. The handle of claim 1 wherein said first side scale is consists of a second piece of integral material.

4. The handle of claim 1 including:

(a). a second external flange, integral with said first piece of integral material, extending outwardly from said second side wall in a second direction away from said channel, said second external flange including a first leaf spring that is an integral part of said first piece of integral material; and

(b). a second side scale, separate from and not an integral part of said first piece of integral material, secured to said frame member adjacent to said second external flange such that said second side wall, said second external flange, and said second side scale define a second external pocket.

5. The handle of claim 4 wherein said internal pocket faces in a third direction and said first and second external pockets face in a fourth direction substantially opposite to said third direction.

6. The handle of claim 4 wherein said first leaf spring of said second external flange is defined by only one cut in said first piece of integral material.

7. The handle of claim 6 wherein said cut is straight and parallel to said second external flange.

8. The handle of claim 1 wherein said first leaf spring is defined by only one cut in said first piece of integral material.

9. The handle of claim 8 wherein said cut is located substantially in said first sidewall.

10. The handle of claim 9 wherein said cut is straight.

11. The handle of claim 9 wherein said cut is parallel to said first external flange.

12. The handle of claim 1 including an independent spring, separate from and not an integral part of said first piece of integral material, arranged in said internal pocket.

13. The handle of claim 12 further including a first tool bit positioned in said internal pocket, said independent spring positioned in said pocket so as to bear upon said first tool bit.

14. The handle of claim 13 wherein said first tool bit is a scissors blade.

15. The handle of claim 13 wherein said first tool bit is a pliers jaw.
