Abstract
A new wrench for holding a nut in the head end when threading and unthreading the nut from a threaded object such as a threaded bolt. The inventive device includes a handle with a head end coupled to the handle. The head end has a first and second faces, and inner and outer side surfaces. The inner side surface of the head end defines an opening through the head end between the first and second faces of the head end. The head end also has a supporting flange extending radially inwards around the inner side surface of the head end. The head end has a break therethrough extending between the inner and outer side surfaces of the head end. The break also extends through an adjacent portion of the supporting flange.
Claims1
A wrench, comprising:
- a handle shaft;
- pair of head ends coupled to opposing ends of said handle;
- each of said head ends comprising:
- said head end having a first and second faces, and inner and outer side surfaces;
- said outer side surface being generally cylindrical in shape;
- said inner side surface of said head end defining an opening through said head end between said first and second faces of said head end, said opening being adapted for receiving a nut therein;
- said inner side surface being generally polygonal and having a plurality of wall portions;
- said head end having a break therethrough extending between said inner and outer side surfaces of said head end, said break extending through at least one of said wall portions of said inner side surface;
- said break of said head end forming a pair of spaced apart and opposing side walls facing each other, said side walls being spaced apart to permit slipping of said head end around a threaded bolt, wherein said side walls are spaced apart less than the width of one of said wall portions, said side walls lying in generally parallel planes;
- said head end having a supporting flange extending radially inwards around said inner side surface of said head end, said support flange being adapted for supporting the nut in said opening formed by said side surface of said head end such that said supporting flange abuts a face of the nut;
- said supporting flange having an inner edge, said inner edge of said supporting flange being generally circular and having a diameter, said inner edge of said supporting flange defining an aperture for extending the threaded bolt through;
- said break extending through an adjacent portion of said supporting flange;
- said break forming a pair of spaced apart and opposing end edges on said supporting flange, said end edges of said support flange facing each other, said end edges being spaced apart generally the same distance said side walls of said break of said head end are spaced apart, one of said end edges being coplanar with one of said side walls, another of said end edges being coplanar with another of said side walls;
- said supporting flange having first and second faces, said first face of said supporting flange lying in a plane generally coplanar with a plane said first face of said head end lies in, said second face of said supporting flange being positioned between said first and second faces of said head end;
- said head end having a thickness defined between said first and second faces of said head end;
- said supporting flange having a thickness defined between said first and second faces of said supporting flange;
- wherein said thickness of said head end is greater than said thickness of said supporting flange;
- and
- wherein said handle is angled away from a first plane of said first face of one of said head such that handle passes through a plane of the second face.
