Abstract
A sport racket includes a head with a shank extending therefrom and a connection section extends from the shank. A shock absorbing sleeve is mounted to the connection section and a handle is mounted to the sleeve.
Description




FIELD OF THE INVENTION




The present invention relates to a handle for a sport racket wherein a soft sleeve is connected between the joint of the handle and the shank so as to absorb shocks.




BACKGROUND OF THE INVENTION




A conventional sport racket generally includes a head with a shank extending from the head and a handle connected to the shank. The head has main strings and cross strings to form a sweet spot which is a preferred area for impacting a ball. An impact shock will be transferred to the user's hand which holds the handle. In order to reduce the affection of the impact, grip strips are used to wrap onto the handle and the grip strips are made of soft material so as to more or less reduce the impact to the hand. However, the diameter of the handle of the racket has its minimum size so as to provide proper structural strength, it is not allowed for the thickness of the grip strips to be a desired or expected thickness. Accordingly, the shock absorbing feature for the conventional sport rackets is not satisfied.




The present invention intends to provide a handle structure for a sport racket and includes a shock absorbing sleeve connected between the shank and the handle to effectively absorb the shocks.




SUMMARY OF THE INVENTION




In accordance with one aspect of the present invention, there is provided a sport racket and comprising a head with a shank extending therefrom and a connection section extends from the shank. A shock absorbing sleeve is mounted to the connection section and a handle is mounted to the sleeve.




The primary object of the present invention is to provide a shock absorbing handle structure for a sport racket by using a flexible sleeve connected between the joint between the handle and the shank of the racket.











These and further objects, features and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawings. which show, for purposes of illustration only, several embodiments in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to

FIGS. 1

to


4


, the sport racket of the present invention comprises a head


10


having a frame


11


and main strings


12


and cross strings


120


are connected within the frame


11


. A shank


13


extends from the frame


11


and a connection section


132


extends from the shank


13


. A first hole


131


is defined radially through the connection section


132


and a handle


21


is connected to the connection section


132


.




A shock absorbing member such as a sleeve


14


made of rubber, thermoplastic rubber (TPR) or PVE is mounted to the connection section


132


, wherein a second hole


141


is defined radially through the sleeve


14


. A first end of a handle


21


mounted to the sleeve


14


and a third hole


211


is defined radially through the first end of the handle


21


so that a pin


15


radially extends through the third hole


211


in the handle


21


, the second hole


141


in the sleeve


14


and the first hole


131


in the connection section


132


to connect the three items. A flexible coating


151


is mounted to the pin


15


so that the sleeve


14


and the flexible coating


151


absorb shocks transferred from the head


10


when impacting a ball. A second end of the handle


21


is an open end and a butt cap


22


is engaged with the second end of the handle


21


. An aperture


221


is defined through the butt cap


22


and a mediate member


23


is engaged with the aperture


221


by a hook-like flange extending from the mediate member


23


.




Referring to

FIGS. 5 and 6

, another embodiment of the handle comprises a flange


213


extending radially inward from an inner periphery of the handle


21


and a hole


212


is defined in the flange


213


. A tubular member


16


is connected in the connection section


132


by ribs


160


, the tubular member


16


contacting the flange


213


when the handle


21


is mounted to the connection section


132


with the sleeve


14


located therebetween. A bolt


214


with a washer


215


made of flexible material mounted to the bolt


214


extends through the hole


212


in the flange


213


and is threadedly engaged with a threaded hole


161


in the tubular member


16


. The washer


215


is located between a head of the bolt


214


and the flange


213


. As shown in

FIG. 7

, a tool


30


may insert into the handle


21


to operate the bolt


214


via the aperture


221


in the butt cap


22


. It is convenient to replace the handle


21


by a longer handle


210


as shown in

FIG. 8

by unscrewing the bolt


214


.





FIGS. 9 and 10

show that a plurality of grooves


17


are defined in an outer periphery of the connection section


132


and each of the grooves


17


has a ring
