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
18
received therein. The rings
18
are made of flexible material so as to absorb shocks of the racket.
While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing: from the scope and spirit of the present invention.
