Abstract

A folding tool comprises a chassis in the form of a generally U-shaped metal band having a base portion and a pair of substantially parallel spaced-apart leg portions, an axle joined to the leg portions adjacent their free ends and transversely spanning the space between them, and a multiplicity of different elongated tools pivotally received on the axle and individually pivotable selectively about the axle between a storage position in which they are received between the leg portions of the chassis and a deployed position in which they extend away from the chassis. A handle having a top wall, a pair of side walls and one end wall receives the chassis and is joined to it, the handle having a bottom opening between the leg portions of the chassis and an end opening between the free ends of the leg portions through which the tools are movable between their storage and deployed positions. The external surfaces of the top and side walls of the handle are contoured to facilitate gripping.

Claims

1. A folding tool comprising a chassis in the form of a generally U-shaped metal band having a base portion at one end and a pair of elongated substantially parallel spaced-apart leg portions extending from the base portion and having free ends remote from the base portions, an axle joined to the leg portions adjacent their free ends and transversely spanning the space between them, a multiplicity of different elongated tools pivotally received on the axle and individually pivotable selectively about the axle between a storage position in which they are received between the leg portions of the chassis and a deployed position in which they extend away from the chassis, and a handle having a top wall, a pair of side walls and one end wall receiving the chassis and joined to it, the chassis being received in the handle with the leg portions engaging the side walls and the base portion engaging the end wall, and the handle having a bottom opening between the leg portions of the chassis and an end opening between the free ends of the leg portions through which the tools are movable between their storage and deployed positions, the external surfaces of the top and side walls of the handle being contoured to facilitate gripping.

2. A folding tool according to claim 1 wherein the external surfaces of the top and side walls of the handle have spaced apart concavities and bulbous portions on either side of the concavities.

3. A folding tool according to claim 2 wherein the concavities are smoothly curved grooves that extend generally transversely and continuously along the top and side walls of the handle.

4. A folding tool according to claim 3 wherein the bases of the grooves define generally a plane that is orthogonal to the top wall, whereby they are adapted for grasping by the fingers and thumb of a user.

5. A folding tool according to claim 1 and particularly adapted for use with bicycles and further comprising a spoke wrench fitting joined to the handle adjacent its end wall and having a wrench-opening defined by jaws for gripping a spoke nut that faces the bottom opening of the handle.

6. A folding tool according to claim 5 wherein the tools in their storage position are set back within the handle to enable the spoke to intrude into the bottom opening and to be straddled by the side walls when the spoke wrench is fitted to the spoke.

7. A folding tool according to claim 1 wherein the axle is a portion of a shank of a bolt that passes through a hole in one side wall of the handle and holes in the chassis and receives a nut that is recessed and keyed into the internal surface of the other side wall of the chassis, whereby the bolt and nut fasten the handle to the chassis.

8. A folding tool according to claim 7 wherein the internal surfaces of the side and end walls of the handle match and engage external surfaces of the chassis and the bottom opening of the handle is bounded by an inturned flange that engages and captures the edge of the chassis.

9. A folding tool according to claim 5 wherein the base portion of the chassis and the end wall of the handle have notches that are aligned with the opening between the jaws of the spoke wrench and receive portions of the spoke and spoke nut when the spoke wrench is fitted to the spoke nut.
