HOCKEY STICK STRUCTURE

Abrégé français

Structure de bâton de hockey comprenant un élément de frappe doté d'une section plane de frappe et d'un col s'étendant de l'une des extrémités de la section de frappe selon un angle et une longueur prédéterminés, ainsi que d'un manche d'une longueur prédéterminée. L'une des extrémités du manche est fixée de façon coaxiale au col. Une partie prédéterminée du manche présente une section transversale en forme d'octogone. La forme d'octogone comporte quatre paires de côtés opposés. L'une des paires de côtés opposés parmi les quatre paires de côtés opposés est une paire dont les côtés opposés servent à l'application d'une force, et ces côtés sont parallèles à l'un des côtés de la section de frappe. La distance entre les côtés opposés servant à l'application d'une force est plus courte que la distance entre les côtés opposés de chacune des trois autres paires.

HOCKEY STICK STRUCTURE
BACKGROUND OF THE INVENTION
The present invention is related to a sport implement, and more
particularly to an improved hockey stick structure.
A conventional hockey stick is composed of a hollow or solid
rectangular stick body and a striking board fitted with one end of the
stick body. In order to enhance the strength of the stick body, the stick
body is made of improved material or the winding angle of the fiber of
the complex material of the stick body is changed. Altematively,
reinforcing members are combined with the stick body to enhance the
strength of the stick body.
However, due to the iimitation of the shape of the stick body, all
the above measures can hardly apparentiy achieve reinforcing effect. To
speak more speciflcally, the conventional rectangular hockey sdck has
two long sides and two short sides. The long sides serve as the force
application sides. Therefore, the thickness of the striking board of the
conventional hockey stick can be hardly increased so that the strength
of the hockey stick can be hardly enhanced. In addition, the rectangular
shape of the conventional hockey stick is not adapted to the
configuration of the hands of a player. Therefore, it is uncomfortable for
a player to hold the hockey stick with the hands. Also, it is hard for the
player to control the striking direction with such hockey stick.
SUMMARY OF THE INVENTION

CA 02506213 2008-05-28
It is therefore desirable to provide an improved hockey stick
structure with greatly enhanced strength. A player can more comfortably
hold the hockey stick with both hands to more precisely control the
striking direction.
According to one aspect of the invention there is provided a hockey
stick structure that includes a striking member having a board-like
striking section and a neck section extending from one end of the
striking section by a predetermined angle and length and a stick body
having a predetermined length. One end of the stick body is coaxially
connected with the neck section. A predetermined portion of the stick
body has a cross-section with a shape of an octagon. The octagon has
four pairs of opposite sides. One pair of opposite sides of the four pairs
of opposite sides are force application opposite sides parallel to a face
of the striking section. The length between the force application
opposite sides is shorter than the length between any other three pairs
of opposite sides.
According to another aspect of the invention there is provided a
hockey stick structure comprising
a striking member having a board-like striking section and a neck
section extending from one end of the striking section by a
predetermined angle and length; and
a stick body having a predetermined length, one end of the stick
body being coaxially connected with the neck section, said hockey stick
structure being characterized in that a predetermined portion of the stick
body has a cross-section with a shape of an octagon, the octagon

having four pairs of opposite sides, one pair of opposite sides of the four
pairs of opposite sides being force application opposite sides parallel to
a face of the striking section, a length between the force application
opposite sides being shorter than the length between any other three
pairs of opposite sides;
wherein the length between any other three pairs of opposite sides
is larger than the length between the force application opposite sides by
a range of 10%-30%.
The present invention can be best understood through the following
description and accompanying drawings wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Please refer to Figs. I to 3. According to a first embodiment, the
hockey stick structure 10 of the present invention is composed of a
striking member 20 and a stick body 30.
The striking member 20 has a board-like striking section 21 and a
column-like neck section 22 integrally connected with the striking
section 21. The neck section 22 extends from a tapered end of the
striking section 21 by a predetermined angle and length. A rear end of
the neck section 22 has an octagonal cross-section.
The stick body 30 Is a hollow octagonal tubular body with a
predetermined length. The octagonal rear end of the neck section 22 is
coaxially fixedly fitted in an octagonal opening of one end of the stick
body 30. It should be noted that the shape of the stick body 30 is not
limited to the hollow tubular body. In other words, any other
complementary measure for serially connecting the stick body with the
3

CA 02506213 2005-05-03
neck section is also included in the scope of the present invention.
The octagon of each of the stick body 30 and the neck section 22
has four pairs of opposite sides. One pair of opposite sides of the four
pairs of opposite sides are force application opposite sides parallel to
the face of the striking section 21. The length between the force
application opposite sides is B, while the lengths between the other
three pairs of opposite sides are respectively A, C and D. The length B
is shorter than the lengths A, C and D. That Is, the lengths A, C and D
are longer than the length B by a range of 10%-30%. To speak more
specifically, the length A between one pair of opposite sides is longest
among the lengths.
According to the above arrangement, the hockey stick structure 10
of the present invention has the following advantages:
1. The octagonal ends of the neck section 22 and the stick body
30 are connected with each other to enhance the connectfon
strength. In the instant of striking the platelet with the hockey
stick, the reaction force Is evenly distributed over every points
of the octagon. In contrast, in the conventional technique, the
stress is concentrated on the corners of the rectangle and the
stick body tends to break. Therefore, the using life of the
hockey stick is prolonged.
2. According to the octagonal shape of the stick body 30, without
Increasing the total weight of the hockey stick, the thickness,

that is, the length B between the force application opposite
sides of the hockey stick can be larger than the thickness, that
is, the length of the short side of the conventional hockey stick.
Therefore, the hardness and strength of the hockey stick can
be enhanced and the striking torque can be increased.
Accordingly, a player can more reliably play the game with the
hockey stick of the present invention.
3. The octagonal shape of the hockey stick of the present
invention is adapted to the configuration of the hand for holding
the hockey stick. Therefore, when a player holds the hockey
stick, the player can have a better and more comfortable
holding feeling. Moreover, the hands of the players can fully
snugly attach to the stick body so as to more precisely operate
the hockey stick and control the striking direction without
deflection.
Figs. 4 and 5 show a second embodiment of the hockey stick 10'
of the present invention, which is similar to the first embodiment. The
difference between the first and second embodiments is that the length
C' between one pair of opposite sides is longest among the lengths and
the lengths A', C' and D' between the pairs of opposite sides are all
longer than the length B' between the force application opposite sides.
The above embodiments are only used to illustrate the present
invention, not intended to limit the scope thereof. Many modifications of
the above embodiments can be made without departing from the spirit

CA 02506213 2005-05-03
of the present invention.
