Abstract

A handle is provided for use with an Allen wrench by means of which leverage and grip on the wrench is improved and protection is provided in the event that the wrench should break during use. The handle is comprised of an elongated shank portion having an axial passage therein to receive the long end of the wrench. A head is provided at the end of the shank portion and formed with a recess perpendicular to and open to the shank passage to receive the short end of the wrench. Releasable retaining means are provided to hold the end of the wrench within the handle during operation thereof.

Claims

1. A handle for use with an L-shaped tool, comprising

(a) a tubular shank portion formed with an axial passage of a length and width sufficient to accommodate the long leg of said tool,

(b) a head disposed at one end of said shank portion and formed with a socket therein open to said passage, to one end of said head and to one side directly opposite said passage, and,

(c) retaining means extending across said one side of said head to restrain that portion of said tool located in said socket,

(d) said retaining means including a resilient member engageable with said head and extensible into said socket,

(e) said resilient member being an elongated leaf spring secured at one end to said head adjacent said socket and normally extending into said socket to engage that portion of said tool located therein, said spring being movable in and out of said socket and to the sides thereof to permit insertion and removal of tools to and from said handle.

2. A handle according to claim 1 wherein said spring is formed with a generally flat portion extending from said one end to the mid portion thereof and formed with a generally U-shaped bend at the free end thereof, said U-shaped bend extendable into said socket to permit manual engagement thereof to move said spring in and out of said socket.

3. A handle according to claim 1 wherein said head is formed with a concave face in the end thereof opposite said one end.

4. A handle according to claim 1 wherein said head is generally cylindrical with the axis thereof perpendicular to the length of said handle, both ends of said head extending to opposite sides of said handle, and the end opposite said one end being knurled about the cylindrical outer surface thereof.

5. A handle for use with an L-shaped tool, comprising

(a) a tubular shank portion formed with an axial passage of a length and width sufficient to accommodate the long leg of said tool,

(b) a head disposed at one end of said shank portion and formed with a socket therein open to said passage, to one end of said head and to one side directly opposite said passage, and,

(c) retaining means extending across said one side of said head to restrain that portion of said tool located in said socket,

(d) said head being generally cylindrical with the axis thereof perpendicular to the length of said handle, both ends of said head extending to opposite sides of said handle, and the end opposite said one end being knurled about the cylindrical outer surface thereof.

6. A handle for use with an L-shaped tool, comprising

(a) a tubular shank portion formed with an axial passage of a length and width sufficient to accommodate the long leg of said tool,

(b) a head disposed at one end of said shank portion and formed with a socket therein open to said passage, to one end of said head and to one side directly opposite said passage, and,

(c) retaining means extending across said one side of said head to restrain that portion of said tool located in said socket,

(d) said retaining means including a pair of retainers moveably and resiliently mounted to said head at the mouth of said socket, said retainers adapted to be spread apart under applied pressure to open said socket and to close against one another when released to close said socket.

7. A handle according to claim 6 wherein said retainer means includes a generally C-shaped spring extending about said head and connected to a retainer at the end of each leg thereof.

8. A handle for use with an L-shaped tool, comprising

(a) a tubular shank portion having opposed ends and formed with an axial passage opening through at least one end thereof and being of a length and width sufficient to removably receive and support one leg of the tool,

(b) a head at said one end of said shank portion, said head having a side opposite said one end of said shank portion, and an end, a socket in said head generally perpendicular to the axial passage to accommodate the second leg of the tool, said socket having laterally spaced sidewalls and a bottom wall, said bottom wall extending from the end of the head generally perpendicular to the axial passage opening, said socket defining a continuous opening through the opposite side of said head and the end of the head, from a point generally aligned with the axial passage to said socket bottom wall, said socket, through said bottom wall, opening to the axial passage,

(c) tool retaining means extending across said opposite side of said head to restrain the second leg of said tool located in said socket, and,

(d) said retaining means including a spring-loaded keeper pivotally mounted to said head about an axis offset from said passage for movement between a position closing at least a portion of said continuous opening, and a position allowing free access through said continuous opening.

9. A handle according to claim 8 wherein said passage extends the full length of said handle and is open at both ends thereof.
