The invention provides a golf club that comprises a club head connected to a club shaft. Within the club head is formed a hollow chamber to pivotally receive an indicator. The indicator can be outwardly turned to assist the practicer in targeting a golf hole. The club shaft and a rear side of the club head are respectively provided with inclination indicator devices to assist the practicer in evaluating the ground inclination.
A golf club, comprising a club head at one side of which is connected a club shaft, wherein the club head inwardly includes a hollow chamber that opens on a rear side of the club head, the hollow chamber being capable of receiving an indicator that is vertically pivotally mounted to the club head, thereby the indicator is allowed to pivotally turn outward to assist a user in targeting a golf hole, or pivotally turn inward to be received within the hollow chamber.
A golf club, comprising club head at one side of which is connected a club shaft enabling a user to handle the golf club, wherein the club shaft and a rear side of the club head are respectively provided with an inclination indicator device.

The invention relates to a golf club and, more particularly, a golf club that is configured in such a manner to be capable of assisting the practicer in targeting and ground inclination evaluating operations.
When playing golf, the practicer traditionally uses a golf club to push a golf ball into a golf hole. However, depending on whether the ground is substantially planar or presents protruded bosses, the intensity and direction of the force applied to hit the golf ball substantially varies. On a horizontal ground, the practicer usually targets the golf hole along a direct line to push the golf ball in the golf hole. However, when the ground presents a slight inclination, the intensity and direction of the hitting force should be determined depending on the position of the golf ball with respect to the inclination, as known by the basic golf amateur. However, an accurate evaluation of the ground inclination only by the practicer's sight perception may be particularly difficult, the angle of view of the practicer's eyes with respect to the golf hole being different from the actual distance between the club head and the golf hole. Hence visual misjudgment often let the practicer think that the golf hole is close to the golf ball, but after the golf ball is actually hit, it does not reach the golf hole.
It is therefore a principal object of the invention to provide a golf club that can assist the practicer in adequately target the golf hole and apply the adequate force to hit the golf ball.
The drawings included herein provide a further understanding of the invention. A brief introduction of the drawings is as follows:
FIG. 1 is a perspective view illustrating a golf club according to a first embodiment of the invention;
FIG. 2 is a perspective view illustrating the assembly of a golf club according to the first embodiment of the invention;
Wherever possible in the following description, like reference numerals will refer to like elements and parts unless otherwise illustrated.
FIG. 1 is a perspective view schematically showing a golf club according to an embodiment of the invention. The golf club of the invention comprises a golf club head 10 that has a hole 11 at an upper surface to attach a golf club shaft 20. On a rear side of the club head 10 is defined a hollow chamber 12 that sidewise opens on one transverse side of the club head 10. A hole 13 is further vertically formed through the club head 10 to enable the insertion of a bolt 14. Through the hole 13, the bolt 14 further passes through a hole 151 of a mounting portion of an indicator 15, a pad 16, and a resilient element such as spring 17 capable of axially extending, to then engage a recessed port 131 below the hole 13. On a sidewall of the rear side of the club head 10 is further fixed a cover 18. An outer peripheral portion of the indicator 15 extends out of the hollow chamber 12 so that a user using his/her hand can pivotally turn the indicator 15 out of the club head 10 around the axis of the bolt 14. On the indicator 15 is marked an arrow 152 that indicates the front of the club head 10.
The mount of the pad 16 between the indicator 15 and the spring 17 enables to prevent the spring 17 from backward rotating the indicator 15 a certain angle to an incorrect position once it is manually released, after the indicator 15 is outwardly extended at 90 degrees. The outer contour of the pad 16 matches the hole 13 through the club head 10, and the indicator 15 is placed in superposition on the pad 16 without being attached thereto. To allow the indicator 15 to be manually turned outward to a precise position of 90 degrees, the mounting portion of the indicator 15 is provided with an abutment portion 153. The abutment portion 153 protrudes in a direction that forms an angle of 90 degrees with the axis of the indicator 15. Therefore, once the indicator 15 is completely outwardly turned 90 degrees, a side periphery of the abutment portion 153 abuts against an inner side of the hollow chamber 12, corresponding to an proper orientation of the arrow 152 properly indicating the front of the club head 10. As a result, the user is aided to target the golf hole with respect to the club head 10.
