2 1. Field of the Invention
3 The present invention relates to a method for making a component of a
4' boot body for a skating shoe, and more particularly to a method for making
a
component of a boot body for a skating shoe to reinforce the hardness and
impact
6 strength of the boot body and to lighten the weight of the boot body.
7 2. Description of Related Art
8 At present, a conventional method of making a boot body of a skating
9 shoe, such as a roller skate, an ice skate or the like, uses leather,
polyvinyl
chloride (PVC), hard polyurethane elastomer (PU) or textile cloth to
11 substantially form the boot body with stitches. To reinforce the hardness
of the
12 boot body, reinforcements, such as chemical sheets, cabretas or leathers
are
13 attached to a lining that is put inside the boot body. Then, a tongue is
joined to the
14 boot body with stitches and a sole is adhered to the boot body. Further,
wheels or
a blade is mounted on the sole to form a skating shoe.
16 Another conventional method of making a boot body uses injection
17 molding to form the boot body. Likewise, reinforcements, such as chemical
18 sheets, cabretas or leathers are attached to a lining that is put inside
the boot body
19 to reinforce the hardness of the boot body. Then, wheels or a blade is
mounted on
the boot body to form a skating shoe.
21 The skating shoe is used in speed skating, figure skating or hockey
22 games so the skating shoe must have a light weight, a high hardness and a
high
23 impact strength to protect a foot of a user from injury and to help the
user to have
24 an excellent performance. However, the reinforcements attached to the
lining do

2
1 not join with the boot body, so the reinforcements directly press the foot
to make
2 the user uncomfortable. Further, the reinforcements increase the weight of
the
3 skating shoe and influence the performarnce of the user.
4 'SiTM1VfARY OF THE INVENTION
The primaty objective of the present invention is to provide a method for
6 making a component of a boot body of a skating shoe to overcome the
7 aforementioned problems.
8 The method for making a component of a boot body of a skating shoe
9 comprises a cutting step, a mold-making step, a coating step and a shaping
step.
The cutting step cuts a flexible sheet to form a base sheet with at least
11 one predetermined coating area. The mold-making step forms a coating mold
12 with at teast one coating slot corresponding to the at least one
predetermined
13 coating area of the base sheet.
14 The coating step applies epoxy resin to the base sheet to form a layer of
epoxy resin coating on the base sheet, aligns the at least one coating slot of
the
16 coating mold with the at (east one predetermined coating area of the base
sheet
,A7 after the layer of epoxy resin coating is solidified and then applies at
least one
18 layer of the epoxy resin to the at least one predetermined coating area
through the
19 at least one coating slot to form at least one reinforcement.
When the epoxy resin is solidified, the at least one reinforcement
21 provides an improved hardness and impact strength to the boot body to keep
a
22 user's foot from injury. Further, the at least one reinforcement is formed
23 integrally on the base sheet to avoid directly pressing the foot and makes
the user
24 comfortably.

opposite side edges and a rear edge. The side sections are mounted
respectively
11 on the opposite side edges of the sole section. The heel section is mounted
on the
12 rear edge of the sole section and joins with the side sections,
13 With reference to Fig. l, a method for making a component of a boot
14 body in accordance with the present invention comprises a cutting step (A),
a
mold-making step (B), a coating step (C) and a shaping step (D).
16 With further reference to Figs. 2, 3 and 6-10, the cutting step (A) is
17 cutting a flexible sheet to form a base slieet (10) with at least one
predetermined
18 coating area. The flexible sheets may be made of hard polyurethane
elastomer
19 (PU) or fiber-textile pre-preg. The base sheet (10) may be a one-piece side
sheet
(1 a, 1 b) corresponding to one of the side sections of the boot body, may be
a
21 one-piece heel sheet (2) corresponding to the heel section of the boot body
or
22 may be a side-plus-heel sheet (11) having multiple optional ventilating
holes (12)
23 and two side sections and a heel section formed in an integral piece. The
side
24 sections of the side-plus-iteel sheet (11) correspond respectively to the
side
CA 02553634 2006-07-24
1 sections of the boot body. The heel section of the side-plus=heel sheet (11)
2 corresponds to the heel sections of the boot body.
3 The mold-making step (B) is forxning a coating mold (40) with at least
4 one coating slot (41) and an optional sole mold (50) with a sole recess

sheet (2)
12 and the sole recess (51) to form the layer of epoxy resin coating (23) and
a sole
13 sheet (30) integrally joined with the layer of epoxy resin coating (23) on
the heel
14 sheet (2).
With further reference to Fig. 5, in a forth embodiment of the coating
16 step (C), fiber textiles (22) or reinforced material such as injection-
molded piece,
17 metal piece and the like can be added to the at least one reinforcement
(20)
18 during applying the epoxy resin to the at least one predetermined coating
area of
19 the base sheet (10) through the at least one coating slot (41) in the
