Abstract
A golf club head and laser pointer arrangement, which includes a golf club head, the golf club head having a recessed chamber and an elongated slot on a face thereof in communication with the recessed chamber, and a laser pointer mounted in the recessed chamber, the laser pointer having a laser firing hole, a lens mounted in the laser firing hole, and a laser diode and driver circuit controlled to emit a laser beam through the lens and the elongated slot on the face of the golf club head for pointing the ball toward the target hole in a golf course.
Description




BACKGROUND OF THE INVENTION




The present invention relates to a golf club head, and more particularly to a golf club head and laser pointer arrangement, in which a laser pointer is mounted in a recessed chamber in a golf club head, and controlled to emit a laser beam for pointing the ball toward the target hole.




The game of golf has become more and more popularly accepted. However, it is not easy to a beginner to drive or put the ball into the hole. A beginner may need a coach to teach driving the ball with the club.




SUMMARY OF THE INVENTION




The present invention has been accomplished under the circumstances in view. According to the present invention, a golf club is equipped with a laser pointer, so that the user can aim the ball at the hole accurately by means of the guide of the laser beam from the laser pointer. According to one aspect of the present invention, the golf club head has a recessed chamber and an elongated slot on the face thereof, and a laser pointer is mounted in the recessed chamber and controlled to emit a laser beam through the elongated slot. According to another aspect of the present invention, the laser pointer can be rotated in the recessed chamber, and positioned in one of a series of angular positions within a limited range.











BRIEF DESCRIPTION OF THE DRAWINGS





FIG. 1

is an exploded view of the preferred embodiment of the present invention.





FIG. 2

is a sectional view of the present invention, showing the laser pointer installed in the recessed chamber in the head of the golf club.





FIG. 3

is a top plain view of FIG.


2


.





FIG. 4

is a schematic drawing showing an application example of the present invention.











DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring to

FIGS. 1 and 2

, the head


1


of a golf club is shown having a circular recessed chamber


11


on a topside wall thereof, and an elongated slot


13


on the face


12


thereof in communication with the recessed chamber


11


. A circular laser pointer


2


is mounted in the recessed chamber


11


. The laser pointer


2


comprises a laser diode and driver circuit (not shown), an on/off switch


21


disposed at the topside thereof, a lens


22


mounted in a laser-firing hole thereof. The laser diode of the laser diode and driver circuit is aimed at the lens


22


.




Referring to

FIG. 4

when the on/off switch


21


is switched on, the laser diode is driven to emit a laser beam


20


through the lens


22


and the elongated slot


13


to point the ball toward the hole.




Referring to

FIGS. 1 and 2

again, an inside annular groove


111


is provided around the peripheral wall of the recessed chamber


11


. The laser pointer


2


comprises an outside annular flange


23


raised around the periphery. After insertion of the laser pointer


2


in the recessed chamber


11


, the outside annular flange


23


is forced into engagement with the inside annular groove


111


inside the recessed chamber


11


, enabling the laser pointer


2


to be rotated in the recessed chamber


11


stably. Alternatively, the laser pointer


2


may be pivotally fastened to the bottom sidewall of the recessed chamber


11


by a rivet.




Referring to

FIGS. 1 and 2

again, a blind hole


24


is formed on the periphery of the laser pointer


2


to hold a compression spring


241


and a steel ball


242


on the compression spring


241


. The compression spring


241


imparts an outward pressure to the steel ball


242


, causing a part of the steel ball


242


to project out of the periphery of the laser pointer


2


. A series of recessed holes


112


are equiangularly arranged around the peripheral wall of the recessed chamber


11


at same elevation corresponding to the steel ball


242


at the laser pointer


2


. After installation of the laser pointer


2


in the recessed chamber


11


, the steel ball


242


is engaged into one recessed hole


112


to hold the laser pointer


2


in position.




Referring to

FIGS. 1 and 3

again, graduations


113


are made on the top side wall of the head


1


around the recessed chamber


11


corresponding to the recessed holes


112


, and an index


25


is marked on the top side wall of the laser pointer


2


corresponding to the graduations


113


. Further, embossed portions


26


are provided at the topside wall of the laser pointer


2


for the positioning of the finger for enabling the laser pointer


2


to be positively rotated in the recessed chamber


11


.




It is to be understood that the drawings are designed for purposes of illustration only, and are not intended for use as a definition of the limits and scope of the invention disclosed. For example, the laser pointer


2


can be fixedly mounted in the recessed chamber


11


in the head


1


. In this case, the aforesaid embossed surface portions


26


, graduations


113


, recessed holes


112


, blind hole


24


, compression spring


241


, and steel ball


242


are eliminated.
