Description
TITLE: METHOD OF MAN~FACTURÆNG AN ICE HOCKEY STICK
This invention relates to a method of manu~acturing an ice hockey stick and in particular one designed to use composite fiber material to fabricate an ice hockey stick.
Ice hockey i9 a game played by two teams of ~ix players each. The players are equpped with skates and wooden sticks. The object of each team is to score point by propelling a disk ~puck) of vulcanized rubber into the opponent's goal while preventing the opponents from driving the puck into the goal the team is defending at the opposite end of the playing area.
However, all kinds of stick are made of wood and generally composed of two portions, i.e. a shaft 1 and a blade 2 as shown in FIG. 18. The shaft 1 is made of a number of wooden board 11 with longitudinal grains stuck together while the blade 2 made of a number of wooden board 21 with iatitudinal grains stuck together. Then the former is engaged with latter by means of resin, However, such stick is made by hand and easy to be broken.
- 20 Therefore, it is an object of the present invention .: . .
.- ' . ~ . ~ ' ''" ' to provide a method of manufacturing an ice hockey stick which may obviate and mitigate the above-mentioned drawbacks.
It is the primary object of the pre~ent invention to provide a method of manufacturing an ice hockey stick which may produce an ice hockey with high strength.
It is another object of the present invention to provide a method of manufacturing an ice hockey stick which is fit for mass production.
It is still another object of the present invention to provide a method of manufacturing an ice hockey stick which is liyht in weight.
It is still another object of the present invention to provide a method of manufacturing an ice hockey stick which is simple in construction.
It is a ~urther object of the present invention to provide a method of manufacturing an ice hockey stick which is economic to produce.
Other objects and merits and a fuller understanding of the present invention will be obtained by those having ordinary skill in the ar-t when the following detailed description of the preferred embodiment lS read in con~unction with the accompanying drawings.

; FIG. 17 shows another preferred embodimen-t of the ; present invention; and FIG. 18 shows the construction of a prior ark ice hockey stick.
With reference to the drawing~ and in particular to FIG. 1 thereof, the ice hockey stick according to the present invention mainly comprises a shaft 1 and a blade 2 which may be formed integrally or separately.
FIG. 12 shows the flow chart for manufacturing an :
ice hockey stick according to the present invention. As illustrated, the glass fiber, carbon fiber or the mixture thereof is fir~t weaved into a fibre cloth and a fiber sleeve and immersed in resin. This technique is well known in the art and has no need to be described here in detail. Then, the fiber cloth is wrapped or otherwise formed into an elongated tubular member 10 as shown in FIG. 2. Further, a set of cores 31, 32 and 3.3 are immersed in resin and then enclosed by a fiber sleeve 47.
The fiber sleeve 47 has a length equal to that of the elongated tubular member 1~. Thereafter, four fiber boards 41, 42, 43, and 44 made of several layers of fiber cloth are disposed on the cores 31, 32 and 33 in orderO
As may be seen in FIG. 4 r the first fiber plate 41 is ~: 15 provided at an intermediate position of the right side with a notch 411 while the second fiber plate 44 formed at the intermediate position of the lower side with a notch 441 so that the notch 411 of the first fiber plate 41 and the notch 441 of the second fiber plate 44 wlll adapt to the neck portion 331 of the core 33 without being wrinkled. Then, the cores 31, 32 and 33 are withdrawn in order from the left with reference to FIG. 3.
As illustrated in FIG. 8, a nylon -tube 5 with a length longer than the fiber sleeve 47 iB passed into the fiber sleeve 47 from the left and then sealed at its left end. Then, the left end of the fiber sleeve A7 is encIosed by a fiber panel 45 ~see FIG. 9) and the elongated tubular member 10 is engaged with the upper end 21 of the blade 20 formed by the cores 31, 32 and 33 (~ee FIG. 10) and then enclosed by another elongated fiber sleeve 47 to form a stick embryo.
Then, the stick embryo is disposed into a ~ould and applied with pressure and heat thereby hardening the stick : embryo and therefore providing an integral tubular ice hockey stick.
~: In addition, the shaft 1 and the blade 2 may be formed separately and then Joined together in the ways as shown in FIGS. l3 and l4.
Further, in order to increase the rigidity of the blade 2, a metal plate 46:is disposed at eaah side of the `
- :
blade 2 after the blade 2 is ~nclosed with the fiber boards 41, 42, 43 and 44 (see FIG. 15). The simpler way to strengthen the blade is further enclosing a piece of fiber cloth 48 or the like on -the surface of the fiber sleeve 47.
As shown in FIG. 17, a plurality of grooves 23 are formed on the side surface of the blade 2 so as to increase the stability of the stick when in hitting or receiving a puck.
Although the present invention has been described with a certain degree of particularity, it is understood that the present disclosure is made by way of example only and that numerous changes in the detail of construction and the combination and arrangement o~ parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
