Description
BACKGROUND OF THE INVENTION
[0001] This invention relates to a particular kind of indoor cloth
wrap sole structure.
[0002] Indoor sole usually take the form of a thin-sole, and more
often than not, they are made of rubber or plastic materials.
However, since the sole is very thin, rubber or plastic is prone to
aging, stiffening, change of color and becoming slippery when wet.
Therefore, these types of soles have many drawbacks for users.
[0003] On Nov. 15, 2000, a Chinese patent application was published
number 00216007.2 titled "A Kind of Cloth Sole". This reference
discloses an indoor shoe having a cloth sole. The reference
discloses that a layer of fabric is added to the rubber or plastic
layer of the shoe bottom to overcome the problems associated with
rubber/plastic-cloth double layer compound shoe sole. This design
does improve the strength of thin shoe soles, as well as increase
in the anti-slippery properties of the sole. However, this
disclosed design has several drawbacks which include: (1) serious
glue exposure; (2) the layers of the compound sole are not clearly
defined; (3) because of the serious glue exposure, the performance
of the anti-slippery properties was minimal (3) the fabric effect
of close wrap sole is not as strong as necessary; and (4) there is
a lack of suitable sewing structure, etc.
[0004] Thus in order to improve the practical application of the
indoor sole disclosed in the `007 reference`, it is necessary that
modifications be made to the above design.
SUMMARY OF THE INVENTION
[0005] The present invention provides an improved type of indoor
cloth wrap sole that has improved ant-slippery properties and a
higher structural strength.
[0006] The present invention provides an improved indoor cloth wrap
sole by providing a bottom layer of cloth and an upper layer of
rubber or plastic. The upper layer and the bottom layer are
heat-pressed together to form a compound structure. The bottom
layer includes thick and compact fabrics, with a slight embossing
structure. The surrounding structure is turned up in whole to form
a boat rim shape.
BRIEF DESCRIPTION OF THE DRAWINGS
[0007] FIG. 1 is a bottom view of the indoor cloth wrap sole
according to the present invention;
[0008] FIG. 2 is a top view of the indoor cloth wrap sole according
to the present invention;
[0009] FIG. 3 is a A-A section view of the present invention;
and
[0010] FIG. 4 is a A-A section and includes a sewing track along
the boat rim.
DETAILED DESCRIPTION OF THE INVENTION
[0011] The present invention relates a novel sole shoe sole. More
specifically, the present invention relates to a novel new sole
shoe, which includes a cloth wrap sole.
[0012] FIG. 1 illustrates the bottom view of an exemplary
embodiment of an indoor cloth wrap sole, which comprises a bottom
layer 1 which in the exemplary embodiment is composed of a cloth
substance. Furthermore, an upper layer 2 is located above the
bottom layer, and in an exemplary embodiment is composed of plastic
or other like materials. The upper layer 2 comprises thick and
compact fabrics, whereas, the bottom layer 1 is comprised of TPR
plastics. In the exemplary embodiment the fabrics comprise of
knitting fabrics but other type of fabrics known to one skilled in
the art may be used. The bottom layer 1 and the upper layer 2 are
heat-pressed together by way of jet molding, which binds the TPR
plastics and the fabrics to form a compound structure.
[0013] In an exemplary embodiment as shown in FIGS. 3 and 4 the
indoor shoe includes embossing structures. Furthermore, the
surrounding rim is turned up in or bent to form an outer boat-rim
configurations along the outer portions of the compound structure.
The embossing structure is composed of bar-shaped protrusions,
which are lined on the bottom in a V-shaped formation. In order to
facilitate the connection of the shoe sole to the upper layer, the
boat rim 4 may bear sewing tracks as shown in FIG. 4.
[0014] In the above design, the slight embossing structure is
composed of lines of protrusions and cave-ins of geometric figures.
The geometric figures may be round, oval, rectangular, square,
in-bars, rhombic or triangular. Other possible designs include, but
are not limited to, crescent, curve-shaped, cross-shaped, wave
shaped, line-shaped or V-shaped, or they may take any other
irregular shapes.
[0015] The lining or layout of the geometric figures may include
the following designs:
[0016] 1. Embossing structure is formed of protrusions of the same
geometric figure.
[0017] a. all protrusions are lined up on the bottom with
regularity.
[0018] b. all protrusions are scattered around the parts of the
sole and heel on the bottom
[0019] 2. Embossing structure is formed of protrusions of a group
of different geometric figures.
[0020] a. protrusions of a group of different geometric figures are
lined up on the bottom with regularity.
[0021] b. Protrusions of a group of different geometric figures are
scattered around the parts of the sole and heel on the bottom.
[0022] 3. Embossing structure is formed by cave-ins of the same
geometric figure.
[0023] a. all the cave-ins are lined on the bottom with
regularity.
[0024] b. All the cave-ins are scattered around the parts of the
sole and heel on the bottom.
[0025] 4. Embossing structure is formed of cave-ins of a group of
different geometric figures.
[0026] a. cave-ins of a group of different geometric figures are
lined on the bottom with regularity.
[0027] b. Cave-ins of a group of different geometric figures are
scattered around the parts of the sole and heel on the bottom.
[0028] In one exemplary embodiment according to the present
invention, there is no sewing track along the boat rim 4 in the
above disclosed design.
[0029] Due to the merits of the new design, there are many
advantages compared to the existing design. First, because the sole
according to the present invention adopts a layer of thick and
compact fabrics, and the rubber or plastic upper layer is
heat-pressed to the bottom layer to form a compound structure, the
whole bottom does have problems with the glue being exposed.
Furthermore, the sole has a clear layer structure with fast
cohesion. The bottom takes on a good fabric effect, and is not
easily color-faded, and attains it cloth-bottom appearance. Because
the shoe bottom uses a layer of thick and compact fabrics, the
bottom layer has excellent flexibility. While heat-pressing, the
two layers are bound seamlessly with each other in fast cohesion.
Another advantage is that due to the fact that the bottom layer
does not include glue, the bottom layer does not loose its
anti-slippery characteristics, but improves its anti-slippery
characteristics and wearability of the shoe bottom. Yet another
advantage of the present invention is that due to the boat rim
portion of the shoe, i.e. completely wrapped structure, it greatly
reinforces the strength of the sewed positions, thus overcoming the
defect of the bottom portion which breaks when the thin shoe
bottoms are being sewed up.
