Abstract
A golf club head includes a main body having a topline and an opposing sole. The main body includes a striking face extending between the topline and sole, and a rear face in opposed relation to the striking face. A sole body is proximate the rear face and extends at least partially along the sole. A peripheral flange extends at least partially about the rear face and is of a flange height, HF, relative to the rear face. A truss protrudes from the rear face and includes a at least a first truss arm which is of a first truss arm height, HT1, relative to the rear face, wherein the difference between HF and HT1 is less than about 0.25 mm.
Claims9
A golf club head comprising:
- a main body having a topline portion, a sole portion opposite the topline portion, a heel portion, and a toe portion opposite the heel portion, the main body including:
- a striking face extending between the topline portion and sole portion;
- a sole body including the sole portion, the sole body defining a sole incline having a sole incline surface opposite the striking face;
- a rear face in opposed relation to the striking face and distinct from the sole incline surface;
- a peripheral flange extending at least partially along the rear face, the peripheral flange comprising an outer flange surface having a flange height, HF, relative to the rear face;
- a truss protruding from the rear face and including a first truss arm comprising an outer first truss arm surface and a first truss arm height, HT1, relative to the rear face, and a second truss arm comprising an outer second truss arm surface and a second truss arm height, HT2, relative to the rear face, the first truss arm and the second truss arm segregating the rear face into a first region proximate the heel portion and distal the toe portion, a second region proximate the toe portion and distal the heel portion, and a third region between the first region and the second region, the third region including a step portion;
- a truss spine extending between the heel portion and the toe portion along the sole incline, the truss spine including an outer truss spine surface;
- a cavity within the third region and recessed relative to the rear face, the cavity at least partially delimited by the truss spine and the step portion;
- a first channel extending along the truss spine and recessed relative to the outer truss spine surface and the sole incline surface;
- wherein:
- HF, HT1, and HT2 have a differential height of greater than 0 and less than about 0.25 mm.
