Abstract

A combination allen/socket wrench is disclosed of the variety having a spinoff design. This wrench has a handle, a pair of outwardly extending parallel support arms each have a respective end is integral with the handle. A bar is mounted between the arms and transverse axis. A plurality of members are rotatably mounted on the bar which extend therefrom radially of the transverse axis of the bar. Each of these members has the end portion thereof formed having a polygonal external configuration of a varying size to one another and each of these members also has a polygonal socket bore formed therein of a varying size to one another whereby a comination allen/socket wrench is provided. A resiliently-biased detent clamp means provides for selectively retaining each of the members against rotational movement. In this fashion during use of the desired wrench portion, the handle may be pivoted on an axis relative to said desired wrench portion.

Claims

1. A wrench comprising:

a handle having a gripping portion and a forward portion;

a pair of outwardly extending parallel support arms, each of said arms having a respective end being integral with the forward portion of the handle;

a bar mounted between the arms on a transverse axis;

at least one member having a first portion rotatably mounted on the bar, and further having a second portion formed integrally with the first portion and extending therefrom radially of the transverse axis of the bar, the second portion including a wrench portion;

each wrench portion having an external polygonal configuration, whereby an allen wrench is provided, and each wrench portion further having a bore of a polygonal shape, whereby a socket wrench is provided; and

means for retaining the member against rotation.

2. A wrench comprising:

a handle having a gripping portion and a forward portion;

a pair of outwardly extending parallel support arms, each of said support arms having a respective end being integral with the forward portion of the handle, said support arms defining a recessed portion therebetween;

a bar mounted between the arms on a transverse axis;

a plurality of members each having a sleeve portion rotatably mounted on the bar, each sleeve portion having a first and a second wrench extension diametrically positioned relative to one another about the sleeve portion, each of said extensions having a first portion mounted on the sleeve for rotational movement therewith and each of said extensions further having a second portion formed integrally with the first portion and extending therefrom radially of the transverse axis of the bar, each of said second portions including a wrench portion;

each of the wrench portions having an external polygonal configuration of a varying size relative to one another, whereby a plurality of allen wrenches are provided, and each wrench portion further having a bore of a polygonal shape, each bore being of a varying size relative to one another, whereby a socket wrench is provided, and means for selectively retaining each of the members against rotational movement on the bar.

3. The wrench of claim 2, wherein each member is mounted on the bar for independent rotational movement.

4. The wrench of claim 2, wherein the means for selectively retaining each of the members against rotational movement is a resiliently-biased detent clip means positioned in the recess between the support arms.

5. The wrench of claim 2, wherein each of the wrench portions is a polygonal shape allen wrench and further wherein each wrench portion is of a varying size relative to each other.

6. The wrench of claim 2, wherein each wrench portion has a bore formed therein, whereby a socket wrench is formed.

7. The wrench of claim 6, wherein each of the bores formed in the wrench portions is of a polygonal shape and further wherein each bore is of a varying size relative to each other.

8. The wrench of claim 2, wherein during use of the desired wrench portion the handle may be pivoted on an axis relative to said desired wrench portion.

9. A wrench comprising:

a handle having a gripping portion and a forward portion;

a pair of outwardly extending parallel support arms, each of said arms having a respective end being integral with the forward portion of the handle, said support arms defining a recessed portion therebetween;

a bar mounted between the arms on a transverse axis;

a plurality of members, each having a sleeve portion mounted on the bar for rotational movement independent of one another, each member further having a first wrench extension and a second wrench extension, said extensions being diametrically positioned relative to one another about the sleeve portion, each of said extensions having a first portion mounted on a respective sleeve for rotational movement therewith, and each of said extensions further having a second portion formed integrally with the first portion and extending therefrom radially of the transverse axis of the bar, each of said second portions including a wrench portion;

each of said wrench portions having an external polygonal configuration of a varying size relative to one another and each of said wrench portions further having a polygonal shape bore formed therein of a varying size relative to one another whereby a combination allen and socket wrench is formed;

a resiliently-biased detent clip means, positioned in the recess between the support arms for selectively retaining each of the members against rotational movement on the bar; and

wherein during use of he desired wrench portion, the handle may be pivoted on an axis relative to said desired wrench portion.
