OUTSOLE WITH AN EMBEDDED FABRIC LAYER
Abstract
An outsole with an embedded fabric layer has a fabric layer and
an outsole. The fabric layer has a top surface and a bottom
surface. The outsole has a bottom surface and multiple non-slip
protrusions. The bottom surface of the outsole is attached to the
top surface of the fabric layer. The non-slip protrusions are
formed integrally on the bottom surface of the outsole, extend
through the fabric layer and protrude out from the bottom surface
of the fabric layer. With the non-slip protrusions, the outsole can
provide excellent anti-slip effect and aesthetically pleasing
decoration. Additionally, import tariffs on the outsole may be
lowered because the shoe is a composite material.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of Invention
[0002] The present invention relates to an outsole, and more
particularly to an outsole with an embedded fabric layer.
[0003] 2. Description of the Related Art
[0004] A conventional outsole is formed using plastics and rubbers.
However, the conventional outsole may be slippery for lack of
non-slip structures on the bottom surface of the conventional
outsole.
[0005] Additionally, because the conventional outsole is made of
plastic materials, some countries may charge larger tariffs on the
conventional outsole than other outsoles comprising different
materials including a cloth cover.
[0006] To overcome the shortcomings, the present invention provides
an outsole with an embedded fabric layer to mitigate or obviate the
aforementioned problems.
SUMMARY OF THE INVENTION
[0007] The primary objective of the present invention is to provide
an outsole with an embedded fabric layer that can form multiple
non-slip protrusions on the fabric layer.
[0008] The outsole with an embedded fabric layer in accordance with
the present invention comprises a fabric layer and an outsole. The
fabric layer has a top surface and a bottom surface. The outsole
has a bottom surface and multiple non-slip protrusions. The bottom
surface of the outsole is attached to the top surface of the fabric
layer. The non-slip protrusions are formed integrally on the bottom
surface of the outsole, extend through the fabric layer and
protrude out from the bottom surface of the fabric layer. With the
non-slip protrusions, the outsole can provide excellent anti-slip
effect and aesthetically pleasing decoration. Additionally, import
tariffs on the outsole may be lowered because the shoe is a
composite material.
[0009] Other objectives, advantages and novel features of the
invention will become more apparent from the following detailed
description when taken in conjunction with the accompanying
drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0010] FIG. 1 is a perspective view of a first embodiment of an
outsole with an embedded fabric layer in accordance with the
present invention;
[0011] FIG. 2 is an enlarged cross-sectional side view of the sole
in FIG. 1;
[0012] FIG. 3 is a perspective view of a second embodiment of an
outsole with an embedded fabric layer in accordance with the
present invention; and
[0013] FIG. 4 is a side view of the sole in FIG. 3.
DETAILED DESCRIPTION OF THE INVENTION
[0014] With reference to FIGS. 1, 2, 3 and 4, an outsole with an
embedded fabric layer in accordance with the present invention
comprises a fabric layer (20, 20A) and an outsole (10, 10A).
[0015] The fabric layer (20, 20A) is porous, allows melted plastic
materials to pass through and has a top surface, a bottom surface,
multiple ribbed protrusions and multiple ribbed recesses. The
ribbed protrusions are formed parallelly on the bottom surface of
the fabric layer (20) and may be straight lines or wavy lines. The
ribbed recesses are defined in the top surface of the fabric layer
(20) and correspond respectively to the ribbed protrusions.
[0016] The outsole (10, 10A) is plastic and has a bottom surface,
an optional heel (11), multiple ribbed protrusions and multiple
non-slip protrusions (12, 12A).
[0017] The bottom surface of the outsole (10, 10A) is attached to
the top surface of the fabric layer (20, 20A).
[0018] The heel (11) is formed on and protrudes from the bottom
surface of the outsole (10).
[0019] The ribbed protrusions are formed on the bottom surface of
the outsole (10), correspond respectively and are mounted in the
ribbed recesses of the fabric layer (20). The ribbed protrusions
may form a pattern of a trademark or a design and are not
limited.
[0020] The non-slip protrusions (12, 12A) are formed integrally on
and protrude from the bottom surface of the outsole (10, 10A),
extend through the fabric layer (20, 20A) and protrude out from the
bottom surface of the fabric layer (20, 20A). Each non-slip (12,
12A) protrusion may be a wary line or a straight line. The non-slip
protrusions (12) protrude further than the ribbed protrusions of
the fabric layer (20). The non-slip protrusions (12, 12A) may form
a pattern of a trademark or a design and are not limited.
[0021] When the outsole (10, 10A) is manufactured, the fabric layer
(20, 20A) is disposed and secured in a mold. Then a molten plastic
is added to the mold to form the outsole (10, 10A) and is pressed
through the fabric layer (20, 20A) to form the non-slip protrusions
(12, 12A). Therefore, the fabric layer (20, 20A) is embedded in the
outsole (12, 12A) and the non-slip protrusions (20, 20A) are formed
on the bottom surface of the fabric layer (20, 20A).
[0022] With the non-slip protrusions (12, 12A), the outsole can
provide excellent anti-slip effect as well as aesthetically
pleasing and unique decoration. Additionally, a tariff on the
outsole with the embedded fabric layer (20, 20A) may be lowered
because the outsole is a composite material.
[0023] Even though numerous characteristics and advantages of the
present invention have been set forth in the foregoing description,
together with details of the structure and function of the
invention, the disclosure is illustrative only. Changes may be made
in detail, especially in matters of shape, size and arrangement of
parts within the principles of the invention to the full extent
indicated by the broad general meaning of the terms in which the
appended claims are expressed.
