    DETAILED DESCRIPTION

    [0034] The following presents a detailed description of various embodiments of the present subject matter with reference to the accompanying drawings.

    [0035] The embodiments of the present subject matter are described in detail with reference to the accompanying drawings. However, the present subject matter is not limited to these embodiments which are only provided to explain more dearly the present subject matter to a person skilled in the art of the present disclosure. In the accompanying drawings, like reference numerals are used to indicate like components.

    [0036] The specification may refer to an, one, different or some embodiment(s) in several locations. This does not necessarily imply that each such reference is to the same embodiment(s), or that the feature only applies to a single embodiment. Single features of different embodiments may also be combined to provide other embodiments.

    [0037] As used herein, the singular forms a, an, and the are intended to include the plural forms as well, unless expressly stated otherwise. It will be further understood that the terms includes, comprises, including, and/or comprising when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. It will be understood that when an element is referred to as being attached or connected, or coupled or mounted to another element, it can be directly attached or connected or coupled to the other element or intervening elements may be present. As used herein, the term and/or includes any and all combinations and arrangements of one or more of the associated listed items.

    [0038] The figures depict a simplified structure only showing some elements and functional entities, all being logical units whose implementation may differ from what is shown.

    [0039] FIG. 1 is an illustration of a golf club with a tubular golf shaft 100. The regular tubular golf shaft has various sections to it. The golf club comprises of a golf shaft, a grip section, a section of the shaft that goes into the grip, the longitudinal hollow tubular shaft the tip end which has the section going into the neck of the club head & the club head which strikes the golf ball.

    [0040] FIG. 2 is an image of this invention of a golf club 200 with a tubular golf shaft, with grooves 202 in a continuous winding pitch forming a spiral thread on the outer surface of the shaft.

    [0041] FIG. 3 shows an exploded view of the shaft showing the grooves 302, the section of the shaft 308 going into the grip 318, the section 306 at the tip end going into the neck of the club head 316.

    [0042] FIG. 4A shows the tubular shaft with the grooves 402 winding along the circumference of the shaft. The angle of the grooves may be adjusted along the longitudinal shaft to achieve better aerodynamics. The grooves 402 are formed on the outside surface of tire golf shaft and running around the circumference of the tubular shaft.

    [0043] FIG. 4B is a zoomed view of the grooves 402 & the height or depth 404 of the grooves. The height of the grooves 404 may vary along the circumference of the shaft. In order to reach the best aerodynamic results, the height of the grooves may be varied along the circumference of the grooves 404.

    [0044] FIG. 4C is a sectional view of the tubular golf shaft showing the hollow area 410 inside the tubular golf shaft. The inside of the shaft may be hollow 410 and the grooves 402 of FIG. 4B are formed on the outside surface of the golf shaft & not touching the inner hollow area 410 of the shaft or the inner walls of the hollow area 410.

    [0045] FIG. 5 is an embodiment of the shaft with grooves 502 formed on the shaft are winding in a variable pitch and variable distance between each groove. Grooves of 502 shows grooves formed as independent, unconnected grooves at variable distance from each other. The grooves placement may be tuned to make the air flow more efficient around the circumference of the golf shaft. As golf shafts are made with variable stiffness, the grooves placement may be tuned accordingly to match with the stiffness of the golf shaft as it moves around the air during a golf swing.

    [0046] FIG. 6 shows an exploded view one of the embodiment of the shaft showing the grooves 602, the section of the shaft 606 going into the grip 616, the section 606 at the tip end going into the neck of the club head 616. According to said embodiment the grooves may not connect from end to end. The grooves may cover a limited area of the circumference of the shaft thereby being non-circular in shape.

    [0047] FIG. 7A shows the tubular shaft with the grooves 702 winding around a limited area of the circumference of the shaft. The angle of the grooves may be adjusted along the longitudinal shaft to achieve bettor aerodynamics. The grooves 702 are formed on the outside surface of the golf shaft and running around the circumference of the tubular shaft.

    [0048] FIG. 7B is a roomed view of the grooves 702 & the height or depth 704 of the grooves. The height of the grooves 704 may vary along a limited area of the circumference of the shaft to order to reach the best aerodynamic results, the height of the grooves may be varied along the circumference of the grooves 704.

    [0049] FIG. 7C is a sectional view of the tubular golf shaft showing the hollow area 710 inside the tubular golf shaft. The inside of the shaft may be hollow 710 and the grooves 702 of FIG. 4B are formed on the outside surface of the golf shaft & not touching the inner hollow area 710 of the shaft or the inner walls of the hollow area 710.
