Abstract

An outsole has a layer of cloth, an adhesive layer mounted on a first side of the layer of cloth and multiple rubber lugs mounted a second side of the layer of cloth. Hence, the outsole can lighten the burden on a user's feet.

Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to an outsole, and more particularly to an outsole that is light in weight.
  • 2. Description of the Related Art
  • With reference to FIG. 4, an outsole (40) of a conventional shoe is made of rubber and has a rough upper surface (41). Multiple rubber lugs (not numbered) are evenly formed on a bottom of the outsole (40) and in alignment with each other. The outsole (40) is then received in a mould and an inner sole (50) is directly formed on the outsole (40) with an EVA foaming method.
  • In a shoe, the outsole (40) contacts the ground, the inner sole (50) is mounted on the outsole (40), and an insert (not shown) is mounted on the inner sole and contacts a user's sole.
  • However, disadvantages of the conventional sole are described as follows:
  • 1. The manufacturing procedure of a conventional sole is complicated. An outsole must first be put into a mould and an inner sole is then formed directly on the outsole.
  • 2. The outsole is completely made of rubber, which is heavy and contributes to the weight of a shoe.
  • Therefore, the invention provides an outsole to mitigate or obviate the aforementioned problems.
    • SUMMARY OF THE INVENTION
  • The main objective of the present invention is to provide an outsole that is easy to produce and is light in weight.
  • 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
  • FIG. 1 is a perspective view of an outsole in accordance with the present invention;
  • FIGS. 2A is an exploded perspective view of the outsole in FIG. 1;
  • FIG. 2B is an enlarged side view of the cloth in FIG. 2A;
  • FIG. 3 is a block flow diagram of the manufacturing steps for the outsole in accordance with the present invention; and
  • FIG. 4 is a flow diagram of manufactunng steps of a conventional outsole.
    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • With reference to FIGS. 1, 2A and 2B, an outsole has a layer of cloth (10), an adhesive layer (20) and multiple rubber lugs (30).
  • The adhesive layer (20) is mounted on an upper end of the layer of cloth (10) and the multiple rubber lugs (30) are evenly mounted on a lower end of the layer of cloth (10) and in alignment with each other such that the outsole is flexible with a user's feet and to absorb shock.
  • With reference to FIG. 3, the manufacturing steps of the outsole are described as follows:
  • a. The layer of cloth (10) is prepared for immersion in PVL-PU liquid.
  • b. The layer of cloth (10) is dried for about 10 minutes after it is completely immersed in PVL-PU liquid for about 5 minutes.
  • c. The layer of cloth (10) is immersed in SA-78S glue for about 5 minutes. Then, the layer of cloth (10) is taken out of the glue for drying for about 20 minutes until completely dried.
  • d. The rubber lugs (30) are formed in a mould and in alignment with each other.
  • e. The layer of cloth (10) is received in the mould and the rubber lugs (30) are covered with the layer of cloth (10). The mould is closed and received in a vulcanization machine for 5.5-6.5 minutes with the temperature of 150°-165°C. so that the layer of cloth (10) is securely mounted on the rubber lugs (30).
  • f. The layer of cloth (10) with the rubber lugs (30) is taken out of the mould and cut and configured to correspond with a user's feet thereby completing the manufacturing process of the outsole.
  • Advantages of the present invention are described as follows:
  • 1. The layer of cloth (10) is light in weight so that the present invention can lighten the burden on a user's feet.
  • 2. The layer of cloth (10) has a rough surface so that an inner sole can be directly mounted on the surface to simplify the manufacturing process.
  • It is to be understood, however, that 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 the details, 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.
