NON-SLIP SOLE STRUCTURE
Abstract
A non-slip sole structure of anti-slip shoes used for stream
trekking and fishing is made of a material with a large coefficient
of friction such as unwoven fabric and having regular or irregular
hollow grooves formed at predetermined positions of the sole to
match with corresponding bumps, formed at the bottom of a shoe
body. When the sole is combined with the bottom of the shoe body,
the bumps at the bottom of the shoe body bottom are passed through
the hollow grooves of the sole respectively and slightly protruded
and exposed to achieve a more secured embedded positioning effect
and provide an appropriate bending and extending deformation margin
to the sole to avoid a stripping problem effectively. The bumps at
the bottom of the shoe body are slightly protruded from the sole
surface to improve an anti-slip grip effect and avoid wearing out
the sole too quickly.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a non-slip sole structure,
and more particularly to the non-slip sole structure for shoes
applied for stream trekking, rock fishing or fish catching to
overcome the conventional structure having the drawbacks of easy
stripping, poor anti-slip effect and high wear out rate, and the
non-slip sole structure of the invention can improve the connection
between a sole and a shoe body and provide a better anti-slip
effect.
[0003] 2. Description of the Related Art
[0004] When conducting activities such as stream trekking, rock
fishing or fish catching, people have safety concerns and may slip
easily due to unstable equilibrium or mosses and algae formed on
rocks under a stream or wave blocks at a seashore, and thus it is
necessary to wear stream trekking shoes, barreled boots, rain
boots, jumpsuit specified shoes or the like. In general, a special
design of a non-slip sole structure of a sole is used to improve
the friction when stepping on the rocks or wave blocks, so as to
reduce the chance of slipping or falling accidentally.
[0005] In the design of special ,shoes of this sort, a sole is
usually made of a material having a large coefficient of friction
such as an unwoven fabric, and the sole is combined with a shoe
body by adhering a glue, and a non-smooth surface of the material
such as the unwoven fabric can provide a larger friction, so that
when a user steps or walks on the slippery rocks or wave blocks,
the shoes can provide an appropriate anti-slip effect.
[0006] However, the structural design of the aforementioned
conventional shoes still have the following drawbacks
[0007] 1. The sole is made of unwoven fabrics and thus has a
loosened structure and a poor durability, so that the sole may be
worn out easily, although it can achieve the expected anti-slip
effect.
[0008] 2. The sole is in a flat shape, and comes with a rough
surface to achieve a larger friction and resistance for an
appropriate anti-slip effect, but the anti-slip function varies
with the environment, particularly if the rocks or wave blocks are
large in size, the grip of the sole will be insufficient, and the
anti-slip effect will be affected seriously.
[0009] 3. The sole and the shoe body are combined by a glue, so
that the gluing position is at a planar contact interface between
the sole and the shoe body only, but the sole is made of a
relatively hard material. As a result, the glued sole cannot bear
bending, and may he stripped easily after being worn for some
time.
[0010] In other words, the conventional non-slip sole structure
still have drawbacks that require feasible solutions and further
improvements.
SUMMARY OF THE INVENTION
[0011] In view of the existing problems and drawbacks of the
conventional non-slip sole structure, the inventor of the present
invention based on years of experience in the related industry to
conduct extensive researches and experiment, and finally developed
a non-slip sole structure of the present invention to overcome the
problems and drawbacks of the prior art.
[0012] Therefore, it is a primary objective of the invention to
provide a non-slip sole structure that can achieve a more secured
combination effect between a sole and a shoe body and avoid a
stripping problem to extend the life of non-slip shoes.
[0013] Another objective of the present invention is to provide a
non-slip sole structure that can improve the overall grip to
enhance the stability of stepping and walking and provide a better
wear, in addition to the more secured combination between the sole
and the shoe body.
[0014] To achieve the foregoing objectives, the present invention
provides a non-slip sole structure comprising a plurality of
regular or irregular hollow grooves formed at predetermined
positions of a sole respectively, and matched with a plurality of
corresponding bumps formed at the bottom of a shoe body
respectively, such that when the sole is combined with the bottom
of the shoe body, the bumps at the bottom of the shoe body are
passed through the hollow grooves of the sole respectively and
slight protruded and exposed to the outside, so as to achieve a
more secured embedded positioning effect and provides an
appropriate bending and extending deformation margin to the sole to
improve the stripping problem. Since the bumps at the bottom of the
shoe body are slightly protruded from a surface of the sole, the
anti-slip grip can be improved, and a quick worn-out of the sole
can be avoided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0027] To make it easier for our examiner to understand the
assembly, the technical characteristics and effects of the present
invention, we use preferred embodiments with related drawings for
the detailed description of the present invention as follows.
[0028] With reference to FIGS. I and 2 for perspective views, FIG.
3 for an exploded view, and FIGS. 4 and 5 for a schematic planar
view and a cross-sectional view of a non-slip sole structure in
accordance with a preferred embodiment of the present invention
respectively, the non-slip sole structure comprises a sole 10 made
of a material with a large coefficient of friction such as an
unwoven fabric, and manufactured according to the shape of the
bottom of a shoe body 20, a plurality of regular or irregular
hollow grooves 11 formed at predetermined positions of the sole 10
respectively, and a plurality of bumps 21 formed at the bottom of
the shoe body 20 and corresponding to the hollow grooves 11
respectively, and each of the bumps 21 has a height slightly
greater than the thickness of the sole 10, such that when the sole
10 and the shoe body 20 are combined and adhered with each other by
a glue, the bumps 21 at the bottom of the shoe body 20 are passed
through the hollow grooves 11 of the sole 10 respectively to
achieve an embedded positioning effect, and a distal surface of
each bump 21 is slightly protruded and exposed to the outside.
During the adhesive operation, the glue is applied to a contact
surface between the sole 10 and the bottom of the shoe body 20, and
also to a contact interface between the bumps 21 and the hollow
grooves 11, or the sole 10 is formed first and then placed in a
mold for performing an injection molding operation of the shoe body
20 to substitute the gluing method, but it is not the target of the
present invention, so that will not be described here. The material
for forming the shoe body 20 is circulated to the hollow grooves 11
of the sole 10 to form the bumps 21, so as to constitute the
non-slip sole structure in accordance with a preferred embodiment
of the present invention.
[0029] With the aforementioned structural design, the hollow
grooves 11 of the sole 10 together with the bumps 21 of the shoe
body 20 can achieve a multi-directional combination and a
position-limit effect, and the design of the hollow grooves 11 can
provide a better bending and extending deformation margin of the
sole 10 for a bendable function to avoid a possible stripping
problem effectively and extend the wearing life of the non-slip
sole structure. In the other hand, the bumps 21 formed at the
bottom of the shoe body 20 are slightly protruded from a surface of
the sole 10, so that the grip and anti-slip effect can be enhanced
to improve the anti-slip performance. When a user steps or walks on
different terrains, the concern of being slipped accidentally can
be avoided, and a large direct contact area with frictions between
the sole 10 and different terrains is achieved, and a too-quick
worn out of the sole 10 is avoided, so as to enhance the value of
the overall practical application.
[0030] With reference to FIGS. 6 and 7 for schematic views, FIG. 8
for an exploded view, and FIGS. 9 and 10 for a schematic planar
view and a cross-sectional view of a non-slip sole structure in
accordance with another preferred embodiment of the present
invention, the non-slip sole structure comprises a sole 10 made of
a material such as an unwoven fabric, a plurality of regular or
irregular hollow grooves 11 formed on the sole 10, a predetermined
number of nails 12 formed at the top surface of the sole 10,
wherein an end of each nail 12 is slightly protruded from the sole
10, and a plurality of corresponding bumps 21 formed at the bottom
of the shoe body 20 bump 21, such that the sole 10 and the shoe
body 20 can be combined and adhered by a glue, or the sole 10 is
placed into a mold for integrally combining the shoe body 20 with
the sole 10 when the shoe body 20 is processed by an injecting
molding process, so as to constitute the non-slip sole structure of
this preferred embodiment of the present invention. The hollow
grooves 11 of the sole 10 together with the bumps 21 of the shoe
body 20 not only provide a more secured embedded positioning
effect, but also provide an appropriate bending and extending
deformation margin to the sole 10 to overcome the stripping
problem. In addition, the design having the bumps 21 formed at the
bottom of the shoe body 20 and slightly protruded from a surface of
the sole 10 and the nails 12 distributed on the sole 10 can improve
the overall anti-slip grip and avoid a quick worn-out of the sole
10, so as to provide a high value of its practical application and
extend the life of the sole 10.
[0031] With reference to FIGS. 11 and 12 for a non-slip sole
structure of the present invention, the non-slip sole structure can
be applied to stream trekking shoes, plastic shoes, or outdoor
boots made of a general diving cloth, or even applied to a shoe
body of a jumpsuit for a general fish catching operation with an
anti-slip function, in addition to the aforementioned non-slip
shoes such as the rain boots. The design having the hollow grooves
11 formed at the sole 10 together with bumps 21 formed at the
bottom of the shoe body 20 can improve the connection between the
sole 10 and the shoe body 20 and provide a better grip to overcome
the problems and drawbacks of the conventional non-slip sole
structure.
[0032] In summation, the non-slip sole structure of the present
invention has the following advantages:
[0033] 1. Since the sole and the shoe body are adhered with each
other by a glue, and the hollow grooves are formed on the sole and
the corresponding bumps are formed at the bottom of the shoe body
bottom, an embedded positioning effect is achieved to provide a
more secured connection and prevent the stripping problem.
[0034] 2. The sole includes the regular or irregular hollow grooves
to achieve a secured connection with the shoe body, and also
provides a better bending and extending deformation margin to
achieve a better durability for bending, so as to improve the
comfort of using the non-slip sole structure.
[0035] 3. Since each of the bumps formed at the bottom of the shoe
body has a height slightly greater than the thickness of the sole,
the end surface of the bumps is slightly protruded from the sole
surface, and the sole is in a full contact with the ground when the
user steps or walks on the ground, so as to avoid a quick worn-out
of the sole and improve the durability and lifespan of the
sole.
[0036] 4. Since the bumps formed at the bottom of the shoe body are
slightly protruded from the sole and disposed separately from one
another at the bottom of the shoe body, therefore the bumps are not
in a full contact with the ground when a user steps or walks on the
ground. In addition, the material of the sole structure is made of
a durable material with an excellent grip effect to improve the
grip and anti-slip effect significantly, and prevent the user from
falling or slipping accidentally, so as to provide a safe and
practical application.
[0037] In summation of the description above, the non-slip sole
structure of the present invention can be applied to specific shoes
for stream trekking, rock fishing or fish catching operation, and
the sole made of a material such as an unwoven fabric is used for
achieving the non-slip function. The hollow grooves formed on the
sole hollow together with the bumps formed at the bottom of the
shoe body can provide a more secured connection and provide a
better bending and extending deformation margin to improve the grip
and durability of the sole structure and overcome the easy
stripping problem of the conventional sole structure, so as to
extend the lifespan of the sole and the safety of using the
non-slip sole structure. Obviously, the invention herein enhances
the performance than the conventional structure and further
complies with the patent application requirements and is duly filed
for patent application.
[0038] While the invention has been described by means of specific
embodiments, numerous modifications and variations could be made
thereto by those skilled in the art without departing from the
scope and spirit of the invention set forth in the claims.
