BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates to hockey and more particularly, to a shock-absorbing hockey stick.
2. Description of the Related Art Conventionally, wooden material is commonly used to make hockey sticks.
Nowadays, fiber-reinforced compound material, e.g. carbon fiber-reinfbrced compound material, is used to make hockey sticks instead of wooden material for the advantages of lightweight and high strength. A hockey stick made of fiber-reinforced compound material generally comprises a hollow stick body and a blade extended from one end of the hollow stick body The blade is separately made and then detachably fastened to the hollow stick body. When hitting the ball with the hockey stick, ;>hock waves are produced and transmitted from the blade through the hollow stick body to the player's hands, interfering with the performance and accuracy of the hitting.
SUMMARY OF THE INVENTION
It is the primary objective of the present invention to provide a hockey stick, which absorbs shock waves produced upon hitting of the blade against the ball, preventing injury to the player's hands or interference of shock waves with the player's performance.

DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. l, a shock-absorbing hockey stick 10 in accordance v~rith a first preferred embodiment of the present invention is shown comprised of a stick body 11 and a shock absorber 20.
The stick body 11 is made of carbon fiber-reinforced compound material or the like, comprising a shaft 12 and a blade 13 at one end of the shaft 12. The shaft 12 is an elongated hollow member comprised of a hollow elongated shaft element 14 and a hollow grip 15 connected tc> one end, namely, the top end of the elongated shaft element 14 remote from the blade 13. The blade 13 is separately made and then fastened to the other end, namely, the bottom end of the elongated shaft element 14. It is to be understood that this structure of sick body is of the known art;
there is also known a conventional design having the shaft made in a unitary piece. During fabrication, the grip 15, the elongated shaft element 14 and the blade 13 are conrnected to one another to form the stick body 11, and then the stick body 11 is processed with a surface treatment, such as polishing and coating.
As shown in FIG. 2, the shock absorber 20 is a block member and mounted inside the shaft 12. The shock absorber 20 can be made of foamed material, soft wood, or any of a variety of elastic materials, preferably rubber. The cross section of the shock absorber 20 is slightly greater than the inner diameter of the shaft 12.
The periphery of the shock absorber 20 is corrugated. Further, the shock absorber 2~0 has two through holes 21, which are extended through the top and bottom sides thereof and are substantially parallel to the elongated axial direction of the shaft 12 when the shock absorber 20 is mounted in the shaft 12.
During assembly of the shock=absorbing hockey stick 10, the shock absorber is press-fitted into one end. of the shaft element 14, keeping about one half of the 20 shock absorber 20 engaged into the shaft element 14 as shown in FIG. 3, and then the other half of the shock absorber 20 outside the shaft element 14 is press-fitted into one end of the grip 15.
When using the shock-absorbing hockey stick 10 to hit the ball, shock v~~aves will be transmitted from the blade 13 through the shaft element 14 toward the,grip 15, and at the same time the shock absorber ZO will absorb shock waves, preventing interference of shock waves with the performance of ball-hitting.
Further, the corrugated periphery of the shock absorber 20 greatly increases friction resistance between the shock absorber ZO and the shaft 12, preventing displacement of the shock absorber 20 relative to the shaft 12. In addition, the shock absorber 20 has two through holes 21 which makes the shock absorber more compressible to be inserted into the shaft 12 easily.
FIG. 4 shows a shock-absorbing hockey stick 30 constructed according to a second preferred embodiment of the present invention. This embodiment is substantially similar to the aforesaid first preferred embodiment with the exception of an additional second shock absorber. According to this embodiment., the shock-absorbing hockey stick 30 comprises a second shock absorber 33 mouni;ed in between the shaft element 31 and the blade 32.
Further, the shock absorber can be made having any of a variety of configurations. In FIG. 5, the shock absorber 40 has a radially extended cross section.
I S In FIG. 6, the shock absorber 50 has the configuration of a block integrally formed of parallel posts 51, and a plurality of through holes 52 axially extended through two opposite sides. In FIG. 7, the shock absorber 60 is a rectangular block member fitting the rectangular inner diameter of the shaft.
FIG. 8 shows still another alternate form of the shock-absorbing hockey stick.
According to this embodiment, the shock absorber 71 of the shock-absorbing hockey stick 70 is made of foam resin or foam rubber directly formed in the shaft of the shock-absorbing hockey stick 70.
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention.
Accordingly, the invention is not to be limited except as by the appended claims.
