EXTENSIBLE STRUCTURE OF A SHOE BODY
BACKGROUND OF THE INVENTION
(a) Field of the Invention
The present invention relates to an extensible structure of a shoe
body, and more particularly to an extensible structure wherein a toe cap
and a seat are disposed with an adjusting device to adjust a size of the
shoe body, so as to achieve a wearing effect that all kinds of foot shapes
and shoe styles can be fitted.
(b) Description of the Prior Art
Skiing is a sport which is enriched with interests and challenges. A
player will ride on a cable car or walk to a top peak of a mountain, and
rush down from a piece of silver peak after viewing beauty of white worid
of mountain covered by the white snow, stretching out elegant and
well-executed arcs on the snow land, stirring snow flakes from the
ground under impact of high speed, and drawing behind him or her with
fantastic white rainbows under reflection of sunlight, thereby
accomplishing a perfect ending to this successful challenge.
In addition to having excellent skill, these players who pursue
extreme excitements rely more on such extraordinary ski equipment as a
I

pair of snow shoes suitable for wearing and being able to be assembled
with ski blades or a snowboard, which is exactly the best tool aliowing
the players to fly in the snow and to challenge the extremes. As in the
Taiwan Utility Model Patent Publication No. 307123, "Structure of a Snow
Shoe," and the Taiwan Utility Model Patent Cert'rf'ication No. 130245,
"Orientation Adjusting Device of a Snow Shoe Fixer on a Snowboard," a
shoe cover which shapes like a shoe, or a fastening belt, is sheathed on
a seat which is assembled on a ski blade or a snowboard, thereby
facilitating a player to put his or her shoes into the shoe covers and seats,
and to control the ski blades or the snowboard. As each player is
provided with different foot shape and size, styles of shoes they wear are
different either. However, this conventional design is not provided with
an adjustable design according to different foot shapes and shoe styles.
Therefore, in application, sheathing among different snow shoes
repeatedly to search for the right size, like choosing the shoes, can be
only taken, which is very troublesome. If no right size can be found, a
wonderful ski experience can be only abandoned, or the snow shoes
which do not fit with the feet are worn grudgingly, which will easily cause
sport injuries or accidents. Moreover, the shoe bodies of conventional
snow shoes or skate shoes are made according to sizes, and the shoe
2
CA 02591367 2007-06-04
body of each size should be plated for manufacturing, which is a burden
to the manufacturing cost.
Accordingly, If there is a klnd of adjustable shoe body design which
can be adjusted to fit different foot shapes and shoe styles, and can
even reduce the related cost for manufacturing the shoe body, then the
advancement and development of industry can be promoted, and users
will be supplied with a better effect of utilization.
SUMMARY OF TNE INVENTION
The primary object of present invention is to provide an extensible
structure of a shoe body, which can improve the shortcoming of a
conventional shoe body that is not provided with an effect of adjusting
the size, and can reduce the related cost for manufacturing.
Accordingly, the body of present invention includes a seat and a toe
cap, wherein the toe cap can be assembled with the seat, and a quick
disassembly member is installed at the assembly place. The seat is
formed with a chute, and an edge of the chute is formed with an open
slot, two faces of* which are in an open shape, with one face being
connected with the chute, and a wall of the other face being opened with
a concave hole. In addifion, the seat is provided with a plurality of
screw holes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention refers to an extensible structure of a shoe
body. Referring to FIG. I and FIG. 2, a body I inctudes a seat 10 and a
toe cap 20, and the toe cap 20 can be assembled with the seat 10, with a
quick disassembly member 30 being located at the assembly place.
The seat 10 is formed with a chute 11 on a vamp, and an edge of
the chute 11 is fornted with an open slot 12, two faces of which are in an
open shape, with one face being connected with the chute 11, and a wa1l
of the other face being opened with a concave hole 121. In addition,
three screw holes 13 are lacated at proper peripheral positions of the
chute 11.
The toe cap 20 is provided with adjusting holes 21 corresponding to
the screw holes 13 of the seat 10, and a bottom of the toe cap 20 is
formed with a sliding block 22 on which is disposed with a teeth row 221,
with the sliding block 22 being sheathed into the chute 11 of the seat 10.
The quick disassembly member 30 is made by a soft and elasf;c
6
CA 02591367 2007-06-04
materiai, with an end of which being formed with four teeth 31, and the
other end of which is formed with a poking part 32, enabling the quick
disassembly member 30 to manifest a folk shape. In addition, an
interior of the quick disassembly member 30 is provided with a position
limiter 33 which abuts a bead member 332 by utilizing an elastic member
331, and the bead member 332 is exposed out of the quick disassembly
member 30.
Upon assembling, the quick assembly member 30 is first emplaced
into the open slot 12 of the seat 10, enabling the poking part 32 of the
quick disassembly member 30 to be exposed on an opening of the open
slot 12, and the teeth 31 of the quick disassembly member 30 to be
protruded into the location where the chute 11 and the open slot 12 are
connected, and to keep at a same horizontal line with the edge of the
chute 11. Next, the sliding block 22 of the toe cap 20 is pushed in for
sheathing, along the chute 11 of the seat 10 corresponding to the sliding
block 22. The sliding block 22 is then gnawed with the chute 11 to
firmly assemble the toe cap 20 with the seat 10 into one integral body,
and the adjusting holes 21 of the toe cap 20 are attached with the screw
holes 13 of the seat 10 for connection. Finally, the teeth 31 of the quick
disassembly member 30 are pushed inward into the chute 11 of the seat
7
CA 02591367 2007-06-04
10, enabling the teeth 31 to be gnawed with the teeth row 221 of the
sliding block 22 of the toe cap 20, and the bead member 332 of the
position limiter 33 of the quick disassembly member 30 to be latched into
the concave hole 121 of the seat 10 by being abutted by the elastic
member 331, thereby accomplishing the assembly. Moreover, as
space of the open slot 12 is larger than volume of the quick disassembly
member 30, the quick disassembly member 30 can move forward and
backward in the open siot 12. As an outline of the quick disassembly
member 30 is abutted with a wall surface of the open slot 12, the quick
disassembly member 30 will be limited and positioned in the open slot 12
without faiiing out of the seat 10, or without aiiowing the parts other than
the teeth 31 to be protruded into the chute 11.
Referring to FIGS. 3 to 5, when accomplishing the assembly, the
teeth 31 of the quick disassembly member 30 are gnawed with the teeth
row 221 of the sliding block 22 of the toe cap 20, enabling the toe cap 20
to be locked with the seat 10 without being able to be extended or shrunk,
thereby allowing the toe cap 20 and the seat 10 to manifest an effect of
firm assembiy.
When the size of the body 1 is to be adjusted, the poking part 32 on
the quick disassembly member 30 is poked first to enable the position
8
CA 02591367 2007-06-04
limiter 33 to escape from the concave hole 121 of the seat 10, and to
enable the quick disassembly member 30 to move freely in the open slot
12. At this time, the quick disassembly member 30 is pulled back
slightly, a{lowing the teeth 31 to escape from the teeth row 221 for
releasing from the gnawing and locking state. As the teeth 31 of the
quick disassembly member 30 and the teeth row 221 of the sliding block
22 of the toe cap 20 can be assembled in multiple stages, when the toe
cap 20 slides in the chute 11 of the seat 10 by using the sliding block 22,
Its position relative to the seat 10 can be extended or shrunk for
adjusting the body I into an adequate size, and then the quick
disassembly member 30 Is pushed forward slightly, allowing the teeth 31
to be gnawed at a different position of the teeth row 221, and the position
limiter 33 to be latched again into the concave hole 121, thereby locking
and fixing the toe cap 20 with the seat 10 once more.
Referring to FIG. 6, screwing members can transfixed into the
adjusting holes 21 and the screw holes 13 to lock the body I at all kinds
of shoes, such as a ski blade, snowboard, skate blade, or roller skate.
As the adjusting holes 21 are in a long chute shape, when the position of
the toe cap 20 relative to the seat 10 is extended or shrunk, the screwing
members can slide on the adjusting holes 21; therefore, the size of the
9
CA 02591367 2007-06-04
body 1 can be adjusted directiy on the ski biade, snowboard, ice skate,
or roller skate, so as to achieve a faster and more convenient adjusting
effect.
Accordingly, by the gnawing structure of the sliding block 22 and the
chute 11, the assembly degree of the body 1 can be strengthened, and
the relative position af the toe cap 20 with respect to the seat 10 can be
extended or shrunk. In addition, through the multi-stage gnawing of the
teeth 31 of the quick disassembly member 30 with the teeth row 221 of
the toe cap 20, the toe cap 20 and the seat 10 can be locked together,
which further achieves a purpose of adjusting the size of the body I to
facifitate wearing for different foot shapes or shoe styles. Furthermore,
as there is no need to plate for manufacturing according to different sizes
like the prior art, related manufacturing cost can be even reduced.
It is of course to be understood that the embodiments described
herein is merely illustrative of the principies of the invention and that a
wide variety of modifications thereto may be effected by persons skilled
in the art without departing from the spirit and scope of the invention as
set forth in the following ciaims.
