TITLE: Improved Sole Structure
(a) Technical Field of the Invention
The present invention relates to an improved sole structure and, more particularly, to a sole structure that employs a main body made of fresh rubber material to combine an intermediate layer made of recycled materials together th a decorative strip formed individually so as to lower the weight of the sole structure as well as afford an aesthetical appearance, adequate cushioning capacity, and comfort in wailcing.
(b) Description of the Prior Art
Under the demands of environmental protection, for reducing the cost of a product, recycled materials are usually utilized in its manufacturing process.
Conventionally, in manufacturing a sole, recycled materials are often added to fresh rubber material at a proportion to achieve the purpose of cost reduction and environmental protection. However, to prevent the physical properties of the sole product from be significantly effected, there isa. proportion limit of adding the recycled materials into the fresh rubber material. If the proportion of the recycled materials is exceeded the limit, defective products may increase. Thus, it is important to conduct a test for the mixtures of fresh rubber and recycled materials before a manufacturing begins.
Also, the recycled materials being added to the fresh rubber matenal may result in irregular patterns and/or colors. It is more difficult to control the appearance of the product made of recycled materials, and thus a further treatment, such as additional coloring or sapping, should be taken to allow the sole product to have a consistent appearance. Furthermore, to manufacture a strip or welt made of recycled material to have aesthetical patterns is not easy.
It is required for skilled persons to stitch a strip made of recycled materials to a sole.
In brief, it is infeasible for a conventional sole structure to contain wear resistance, cushioning capacity for providing comfort in walking, as well as an aesthetical appearance at the same time. Thus, there is a need to develop an improved sole structure to contain those characteristics.
To eliminate the drawbacks of conventional sole structures, after constant efforts on the research and development of shoe products, the applicant has contrived an improved sole structure, in which a main body made of flesh rubber material is employed to cooperate with an intermediate layer made of recycled materials together with a decorative strip being individually fomied so as to afford the sole structure an aesthetic appearance and cushioning capacity to bring comfort in walldng.
SUMMARY OF THE INVENTION
The primaty object of the present invention is to provide an improved sole structure that can be manufactured with lower weight in a convenient way, and can afford an aesthetical appearance, adequate cushioning capacity, and S more comfort in walking.
According to one aspect of the present invention, the improved sole structure comprises a. main body, an intermediate layei; and a decorative strip; in which the main body, being made of rubber material having good physical pmperties, has a bottom surface provided with antklip ribs and a top surface defIning a recess having specific depths respectively for a heel portion and a sole portion thereof; the intermediate layer, being made of nixture of recycled materials, is shaped to confonn to the recess of the main body, the intermediate layer being disposed in the recess of the main body to be heated and pressed so as to nil the recess of the main bod)ç so that the sole structure has a flat top surface, a wear resistance and anti-slip characteristics, and can provide comfort in walking.
According to another aspect of the present invention, the improved sole stmcture further comprises a plurality of protrusions formed on a top surface of the recess defined on the main body.
According to still another aspect of the present invention, the intermediate layer is formed into a meshed structure according to a force applied by foot while in walking.
Other objects, advantages, and novel features of the present invention will S become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
To allow the features and applicability of the present invention to be easily understood, an embodiment with reference to the accompanying drawings will be detailed in the following paragraphs.
As shown in FIGS. 1-4, an improved sole structure of the present invention comprises a main body 10 or outsole, an intermediate layer 12, and a decorative strip 14 for enveloping a periphery of the main body 10, in which the aforementioned components may he preformed or pre-molded before a bonding process begins. The main body 10 is principally made of fresh rubber material having good physical properties, with suitable and necessary additives or fillers for ease of molding. The main body 10 has a bottom surface formed with a pattern of ribs for pmviding anti-slip fijnction and a top surface defining a recess 11, the depth of which varies along the main body in which each portion, such as heel portion or sole portion, may have a specific depth.
An intermediate layer 12, being made of mixtures of recycled materials, is shaped conforming to the recess 11 of the main body 10, so that it can be tightly disposed in the recess 11 of the main body 10. Within thc recess 11 is provided a plurality of protrusions 13 or ribs or a rough surface for ease of bonding the intermediate layer 12 to the main body 10 by heat press in a molding process. Alternatively, the intermediate layer 12 can be provided with pmtrusions 13 or ribs or a rough surface at a bottom surface thereof to achieve the above purpose. The intermediate layer 12 can be formed into a meshed structure according to a forte applied by foot while in walking. Such meshed structure can lower the weight of a so]e and provide comfort while in walking.
A decorative strip 14, being made of fresh rubber material, is formed into an integral closed element conforming to the periphery of the main body 10.
The decorative strip 14 can he formed with various colors and/or patterns according to aesthetical considerations. Furthermore, the decorative strip 14 can be formed into a curved structure having a decorative pattern thereon.
The primaiy feature of the present invention is that the main body 10 is formed of fresh rubber material having good physical properties, the intermediate layer 12 is formed of mixtures of recycled materials, which can be bonded to the main body 10 by heat press to form an integral structure, which in turn cooperates with the closed decorative strip 14, Although the sole structure is constructed of different components, in a practical manufacturing process, the main body 10 and the intermediate layer 12 can be heat-pressed on the same mold tools to form an integral structure, The decorative strip 14 can be bonded to the integral structure by heat or glue along the periphery of the main body or outsole without stitching threads and then be trimmed along
S
the periphery thereof to obtain a neat appearance. Thus, the manufacturing process of soles can be greatly simplified. In addition, a sole can have an aesthetic appearance, a flat top surface, a wear resistance, and antislip characteristics according to the present invention, whercby the sole can provide much more comfort in walking.
Furthennore, the intermediate layer 1.2 is formed into a meshed structure, which allows the sole structure to have cushioning capacity so as to provide much more comfort for a user. in addition, the meshed structure can lower the weight of a sole and thus its manufficturing cost can be reduced.
Still furthermore, the decorative strip 14 can be individually designed with various colors and/or patterns to provide an aesthetical appearancc. For example, the decorative strip 14 can be designed with bumps or marks 141 being equally spaced, which looks like a stitching thread.
in light of the foregoing, the improved sole structure of the present invention employs a main body 10 of fresh rubber material to cooperate with an intermediate layer 12, made of recycled materials, and a decorative strip 14 to allow the entire sole structure to be manufactured in a convenient way. The present invention not only provides more comfort in walking but also has a more aesthetic appearance. It is believed that the present invention is a creation with novelty and usefulness.
Alihough the present invention has been described with a certain degree of particu'arity, it is understood that the present disclosure is made by way of example only and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention. hereinafler claimed. 1 0
