Full Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a golf club head, and more particularly to a golf club head with shock absorbing material embedded inside the golf club head to absorb shock from the striking of a golf ball. 
     2. Description of Related Art 
     When a golfer is striking a golf ball, the counter force from the golf ball is applied directly to the golf club, which in turn is transmitted to the golfer. Therefore, after years of golfing on the golf courses, the accumulated stress on the golfer is enormous. The most common ailment from golfing due to the counter force is the wrist injury. This is because the golfer&#39;s wrist receives most the counter force so that after a period of time enjoying this past time, most golfers need to seek professional help to treat the discomfort. 
     In order to avoid the discomfort, especially when striking the golf ball, most golf club manufacturers nowadays install shock absorbing material inside the golf club head to reduce the shock to the golfer. Because the shock absorbing material can not withstand the heat during a welding process while manufacturing the golf club head, the shock absorbing material normally has a size slightly larger than the space inside the golf club head such that the manufacturer has to stuff the shock absorbing material inside the space in the golf club head. Thereafter, the manufacturer uses a cap and positioning elements such as screws, bolts or the like to secure the position of the shock absorbing material. However, this process will inevitably increase the cost in making the required mold and the shock absorbing material, after being pressed into the space inside the golf club head, is not able to effectively absorb the shock. Thus the conventional structure and method of stuffing the shock absorbing material inside the golf club head are not complete solutions to the existing problems. 
     To overcome the shortcomings, the present invention tends to provide an improved golf club head to mitigate the aforementioned problems. 
     SUMMARY OF THE INVENTION 
     The primary objective of the present invention is to provide an improved golf club head with shock absorbing material embedded inside the golf club head to effectively absorb shock from striking the golf ball. 
     Another objective of the present invention is to provide a baffle inside the golf club head to be spaced apart from the striking face so as to define therebetween a receiving space to receive therein a shock absorbing material. 
     To further strengthen the baffle, the baffle has ribs formed on a side face opposed to the striking face. 
     Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference to  FIGS. 1 and 2 , the golf club head in accordance with the present invention includes a hollow body ( 10 ), a striking face ( 20 ) and a top cover ( 30 ). 
     The hollow body ( 10 ) has a neck ( 11 ) extending from one end of the hollow body ( 11 ) to receive therein a golf club (not shown), a threaded hole ( 12 ) is defined through the neck ( 11 ) to communicate with the interior of the hollow body ( 10 ) and a through hole ( 13 ) defined through an outer face of the hollow body ( 10 ) to communicate with the interior of the hollow body ( 10 ). An opening ( 101 ) is defined to mate with the top cover ( 30 ) and a side hole ( 15 ) is defined to mate with the striking face ( 20 ). 
     A baffle ( 14 ) is formed inside the hollow body ( 10 ) to be close to a peripheral edge of the side hole ( 15 ). The baffle ( 14 ) is substantially a plate with a rear surface enclosed in the body ( 10 ) and a front surface facing the side hole ( 15 ).The rear surface has a cruciform rib structure protruded therefrom, and an intersection portion of the cruciform rib is configured as a diamond shape. At least one air escape hole and preferably three escape holes are defined through the baffle ( 14 ) at a portion distant from the through hole ( 13 ). A recess ( 143 ) extends along a lower periphery of the front surface. 
     With reference to  FIGS. 3 and 4 , it is noted that after the top cover ( 30 ) and the striking face ( 20 ) are respectively mounted to cover the opening ( 101 ) and the side hole ( 15 ), a receiving space ( 16 ) is defined between the striking face ( 20 ) and the baffle ( 14 ). Further, the provision of the recess ( 143 ) is able to prevent the baffle ( 14 ) from being otherwise damaged from the heat from the welding of the striking face ( 20 ) to the hollow body ( 10 ). 
     Thereafter, due to the communication among the threaded hole ( 12 ), the through hole ( 13 ) and the interior of the hollow body ( 10 ), the manufacturer is able to add in a shock absorbing material ( 40 ) via the through hole ( 13 ) with the threaded hole ( 12 ) being blocked by any appropriate device. After the receiving space ( 16 ) is filled with shock absorbing material ( 40 ), the shock absorbing material ( 40 ) is hardened inside the receiving space ( 16 ) by a known process and thus the through hole ( 13 ) is blocked. Because the shock absorbing material ( 40 ) is hardened in the receiving space ( 16 ), the shock absorbing material ( 40 ) is able to securely adhere to side walls defining the receiving space ( 16 ). This is because the shock absorbing material ( 40 ) normally has adhesion ability such that while the shock absorbing material ( 40 ) is hardening, the adhesion ability of the shock absorbing material ( 40 ) is able to securely connect the shock absorbing material ( 40 ) to the side walls of the receiving space ( 16 ). 
     In order to have the best weight ratio of the golf club head, the baffle ( 14 ) has a thickness between 0.2˜0.3 mm and the rib ( 141 ) has a thickness of 1 mm. 
     It is to be noted that when the receiving space ( 16 ) is gradually filled with the shock absorbing material ( 40 ), air inside the receiving space ( 16 ) will escape from the air escape holes ( 142 ) to the interior of the hollow body ( 10 ). Then the air will escape from a slit ( 102 ) defined through a periphery of the hollow body ( 10 ) to the surrounding atmosphere. 
     In summary, because the shock absorbing material ( 40 ) is able to securely adhere to the side walls defining the receiving space ( 16 ), when the striking face ( 20 ) is used to strike the golf ball, the shock wave from the striking motion will be effectively absorbed by the shock absorbing material ( 40 ) and thus the golfer&#39;s wrist is protected. 
     It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
