Definitions

  • the present invention relates to a shoe sole, more particular to a waterproof and breathable shoe sole and a pair of shoes with the same.
  • Sweat glands of the foot sole which are mainly located between the toes, and at the anterior and central area of the foot sole, form an important sweating part of the human body. What is more, the sweat secreted by human's foot skin usually gathers on the foot sole. As the shoe sole absorbs the sweat for a long time and the sweat gathered on the shoe sole cannot be timely evaporated, it is unavoidable that stink rises, bacterium grows and people suffer from foot disease. Stink is particularly easy to happen to teenagers who often wear sport shoes. The existing shoes, taking sport shoes for example, achieve the function of sweat evaporation by improving the breathability of shoe uppers.
  • each film buckle corresponds to a retaining groove, repeating gluing is required in order to fix the film buckle, and the operation of waterproof fixing is complicated; 2.
  • the production has low degree of automation.
  • I as the inventor, filed another utility model patent application No. 203234113U on Apr. 8, 2013. It discloses a waterproof and breathable shoe sole internally installed with a breathable film buckle, comprising a plurality of grooves distributed on the upper surface of the shoe sole. The grooves are respectively formed at the bottom with at least one through hole passing through the shoe sole to the bottom surface.
  • a film buckle is mounted inside the groove, and the film buckle structure comprises a ring corresponding to the groove and at least one piece of waterproof and breathable film stretched over the ring.
  • upper end of the film buckle is provided with a waterproof chamfer as an extension of outer edge of the upper end of the film buckle.
  • a waterproof chamfer as an extension of outer edge of the upper end of the film buckle.
  • the waterproof and breathable film buckle since it needs the shoe sole to serve as a platform, a platform or a surface in a certain shape, e.g. circle, should be provided at the position where the keel lies instead of the keel. In this way, the waterproofing effect may be realized, but meanwhile the weight of the shoe sole may be increased. In addition, the highly targeted mold design may bring difficulties for the design. 2.
  • the shoe undersole and the waterproof and breathable film are directly pressed, glued and integrated together, therefore, holes on the shoe undersole and hole locations of the film buckle shall be distributed in one-to-one correspondence, or else the mismatching of which may otherwise lead to rupture of the waterproof and breathable film.
  • the present invention aims to provide a waterproof and breathable shoe sole. With the design of a waterproof and breathable film assembly, it incorporates the waterproof and breathable film into the shoe sole with minimum changes for the existing enclosed-style shoe sole, and reaches a waterproof and breathable effect. Meanwhile, the present invention also provides shoes with the waterproof and breathable shoe soles.
  • the present invention provides a technical solution as follows:
  • a waterproof and breathable shoe sole comprising a shoe undersole and a waterproof and breathable film assembly. At least one through hole is formed on the upper surface of the shoe undersole, passing through the shoe sole to reach the bottom surface of the shoe sole.
  • the waterproof and breathable film assembly comprises a waterproof and breathable film and an upper waterproof bearing plate and a lower waterproof bearing plate attached to the upper side and the lower side of the waterproof and breathable film.
  • the waterproof and breathable film assembly is mounted on the upper surface of the shoe undersole, and the lower waterproof bearing plate is positioned above the at least one through hole.
  • An upper breathable groove and a lower breathable groove are respectively formed at the corresponding positions on the upper waterproof bearing plate and the lower waterproof bearing plate, and the lower breathable groove corresponds to at least one through hole.
  • a groove is formed on the upper surface of the shoe undersole, the at least one through hole is positioned on the bottom surface of the groove, the waterproof and breathable film assembly is installed inside the groove, and the lower waterproof bearing plate is positioned at the bottom of the groove.
  • a layer of buffer fabric or a net structure for sand prevention is arranged between the lower waterproof bearing plate and bottom of the groove.
  • a waterproof strengthening layer is arranged in the gap between the upper waterproof bearing plate and upper surface of the shoe undersole.
  • the present invention also provides a pair of shoes comprising shoe uppers and shoe soles, wherein the shoe uppers and shoe soles are fixed with each other, the shoe soles are the waterproof and breathable shoe soles.
  • Making process is as follows: Firstly, forming a shoe undersole with breathable through holes;
  • the waterproof and breathable film assembly comprises a waterproof and breathable film, and waterproof bearing plates which have a certain thickness and are respectively fixed and attached to the upper side and the lower side of the waterproof and breathable film.
  • Both the upper and lower waterproof bearing plates comprises corresponding breathable grooves with same or corresponding shapes.
  • the outer edge of the grooves on the lower waterproof bearing plate could be slightly larger or smaller than the outer edge of the grooves on the upper waterproof bearing plate. That is, outer edges of the upper and lower waterproof bearing plates may be designed to be different.
  • improved waterproofing may be provided along the outer edges. Either the upper waterproof bearing plate or the lower waterproof bearing plate itself may strengthen the waterproofing.
  • Such shoe sole has a good waterproofing effect, it is easy to manufacture and has stable property. Moreover, it is also applicable for plastic shaping of different shoes made from various materials like rubber, PU, EVA, TPR, TPU, etc.
  • Post shaping shoe sole is not limited to half foot sole.
  • the supporting surface of the shoe sole is not limited to any certain shapes.
  • shapes of the breathable grooves of the upper and lower bearing plates are not limited to regular shapes like circle, square, rectangle, ring, etc, but may also be irregular shapes which facilitate breathing in most cases.
  • the present invention has the following advantages:
  • the present invention makes an improvement over the existing waterproof and breathable film buckle.
  • the shoe sole itself is not used as a supporting surface for waterproofing.
  • the waterproof and breathable film buckle is replaced by a waterproof and breathable film bearing assembly, which comprises a waterproof and breathable film sandwiched between an upper waterproof bearing plate and a lower waterproof bearing plate.
  • the waterproof and breathable film bearing assembly forms an entire waterproof and breathable unit, and the waterproof bearing plates are designed to support human's weight in order to protect the waterproof and breathable film from being crushed by human's weight and from leakage.
  • minimum changes are made to the structure and appearance of previous shoe sole, improving waterproofing, reducing production difficulty, and enlarging breathing area.
  • the design for waterproofing and breathing tends to be more simple, convenient, reasonable and efficient.
  • Most shoe soles made from different materials could be easily incorporated with the waterproof and breathable film and the functions of waterproofing and breathing could be achieved.
  • the upper and lower bearing plates are easy to produce, and it may be applied to shoe soles of all kinds, with different materials, appearances, or even functions. Moreover, factories or production lines specialized in producing the waterproof and breathable film and the waterproof bearing plate may be set up, such that the production efficiency could be effectively increased.
