Abstract

A folding hand tool set having a one-piece, completely integral, plastic handle and a plurality of hand tools rotatably mounted thereto. The one-piece, completely integral, plastic handle is preferably constructed from a fiber reinforced thermoplastic. Spacers may be provided for rotationally isolating the hand tools. The folding hand tool set is capable of transmitting more then 110.0 Newton meters of torque without compromising the integrity of the one-piece, completely integral plastic handle. A one-piece, completely integral, plastic handle for receiving hand tools is also disclosed. The handle can withstand at least 30 Newton meters of torsional force without compromising the integrity of the handle.

Claims

1. A folding hand tool set, comprising:

a handle including first and second elongated side walls arranged in a generally parallel configuration and joined by a center rib, a first mounting end, and an outer gripping surface, the center rib being positioned to form a first recess having a longitudinal axis for receiving hand tools;

at least one slot located proximate the first mounting end;

a plurality of hand tools rotatably mounted to the first mounting end by a fastener, the hand tools being rotatable from a first position at least partially within the first recess to a second extended position; and

at least one discrete spacer located between at least two hand tools, the spacer having a center hole and a distal portion, the fastener extending through the center hole and the distal portion engaged with the slot.

2. The apparatus of claim 1 wherein the distal portion inhibits rotation of the spacer relative to the handle.

3. The apparatus of claim 1 wherein the spacer comprises an irregular shape.

4. The apparatus of claim 1 wherein the spacer comprises one of a metal or a polymeric material.

5. The apparatus of claim 1 wherein the at least one slot comprises a plurality of discrete slots arranged generally perpendicular to an axis defined by the fastener.

6. The apparatus of claim 1 wherein at least one spacer is located between each of the hand tools.

7. The apparatus of claim 1 wherein the spacer is releasably engaged with the slot.

8. The apparatus of claim 1 wherein the slots are located in the handle.

9. The apparatus of claim 1 wherein the center rib further includes center reinforcing means proximate the center portions of the first and second side walls.

10. The apparatus of claim 9 wherein the reinforcing means comprises a "s-shaped" curve proximate the center portions, the longitudinal axis of the handle intersecting the "s-shaped" curve in at least two locations.

11. The apparatus of claim 1 wherein the hand tools comprise a plurality of hex-shaped wrenches.

12. The apparatus of claim 1 wherein the handle is constructed from a thermoplastic material selected from a group consisting of acrylonitrile-butadiene-styrene, acetal, acrylic, polyamide nylon 6-6, nylon, polycarbonate, polyester, polyether etherketone, polyetheride, polyether sulfone, polyphenylene sulfide, polyphenylene oxide, polystyrene, polysulfone, and styrene acrylonitrile.

13. The apparatus of claim 1 wherein the second extended position of at least one of the hand tools is approximately 270 degrees from the first position.

14. A folding hand tool set, comprising:

a handle including first and second elongated side walls arranged in a generally parallel configuration and joined by a center rib, a first mounting end, and an outer gripping surface, the center rib being positioned to form a first recess having a longitudinal axis for receiving hand tools;

at least one slot formed in a portion of the handle proximate the first mounting end;

a plurality of hand tools rotatably mounted to the first mounting end by a fastener, the hand tools being rotatable from a first position at least partially within the first recess to a second extended position; and

at least one discrete spacer located between at least two hand tools and engaged with the fastener, the spacer having a distal portion engaged with the slot.

15. A folding hand tool set, comprising:

a handle including first and second elongated side walls arranged in a generally parallel configuration and joined by a center rib, a first mounting end, and an outer gripping surface, the center rib being positioned to form a first recess having a longitudinal axis for receiving hand tools;

at least one slot located proximate the first mounting end;

a plurality of hand tools rotatably mounted to the first mounting end by a fastener, the hand tools being rotatable from a first position at least partially within the first recess to a second extended position; and

at least one discrete spacer means located between at least two hand tools and engaged with the fastener for rotationally isolating adjacent hand tools, the spacer having distal means for engaging with the slot.
