Abstract
A wrench extension includes a body having an end with a coupling section for releasably coupling with an open end of a handle of a wrench that has an adjustable head pivotably connected to the other end of the handle. The wrench extension further includes a retaining member mounted to the end of the body for securely clamping the open end of the wrench on the end of the body. The retaining member is movable relative to the body to allow coupling of the wrench extension with wrenches with variously sized open ends.
Claims20
A wrench extension comprising:
- a body comprising a first end and a second end, with the first end comprising a stop, with the first end further comprising a coupling section adapted to releasably couple with an open end of a handle of a wrench having an adjustable head pivotably connected to another end of the wrench, with the coupling section comprising a smaller diametrical section and a larger diametrical section, with the smaller diametrical section having a first side and a second side, with the larger diametrical section having a first arcuate section and a second arcuate section, with the first and second arcuate sections extending from and directly interconnecting the first and second sides, with the first and second arcuate sections being arcuate having an end diameter, with the first and second sides being spaced less than the end diameter, with the first arcuate section being diametrically opposed to and spaced from the second arcuate section, with the larger diametrical section comprising an outer threading extended from the second end of the body to the stop on the first and second arcuate sections;
- and
- a retaining member comprising an inner threading for threadedly engaging with the outer threading of the larger diametrical section, with the inner threading defining a retainer diameter, with the end diameter equal to the retainer diameter, with the retaining member being moveable relative to the body toward and away from the stop allowing the open end of the wrench to be clamped between the retaining member and the stop so that the body drives the handle of the wrench.
A combination comprising:
- a wrench comprising a handle, an open end on a first end of the handle, and an adjustable head on a second end of the handle, the adjustable head being retainable in a desired angular position relative to the handle;
- and
- a wrench extension comprising:
- a body comprising a first end and a second end, with the first end of the body comprising a stop, with the first end further comprising a coupling section releasably coupling with the open end of the wrench, with the coupling section comprising a smaller diametrical section and a larger diametrical section, with the smaller diametrical section having a first side and a second side, with the larger diametrical section having a first arcuate section and a second arcuate section, with the first and second arcuate sections extending from and directly interconnecting the first and second sides, with the first and second arcuate sections being arcuate having an end diameter, with the first and second sides being spaced less than the end diameter, with the first arcuate section being diametrically opposed to and spaced from the second arcuate section, with the larger diametrical section comprising an outer threading extended from the second end of the body to the stop on the first and second arcuate sections;
- and
- a retaining member mounted to the first end of the body, with the retaining member comprising an inner threading for threadedly engaging with the outer threading of the larger diametrical section, with the inner threading defining a retainer diameter, with the retaining member being moveable relative to the body for securely and releasably clamping the open end of the wrench on the first end of the body, with the end diameter equal to the retainer diameter of the retaining member, with the retaining member being moveable relative to the body toward and away from the stop allowing the open end of the wrench to be clamped between the retaining member and the stop, with the wrench extension driving the handle and the adjustable head of the wrench.
