    •  DETAILED DESCRIPTION OF THE INVENTION
  • With reference to FIGS. 1-3 of the drawings, the shoe sole of the present invention preferably includes an air chamber 5 formed of a resilient or elastic material, such as rubber, resilient polymer or other elastic materials, and a sole member 6 securely coupled with the air chamber 5.
  • The air chamber 5 preferably resembles a heel shape of a shoe to fit in the heel portion of the shoe sole, as shown in FIGS. 1 and 2. The air chamber 5 includes an air port 3 preferably at a front side of the heel-shaped air chamber 5, to which an air passageway or conduit 2 is coupled, extending in a lateral direction. An air valve 1 is coupled at the terminal end of the air conduit 2, in which a tip portion of the air valve 1 preferably extends externally from the side surface of the shoe sole to allow the wearer of the shoe to adjust or control the air valve.
  • According to one preferred embodiment of the present invention, the air chamber 5 includes one or more through-holes 4 formed through the upper and lower surfaces of the air chamber 5, and one or more grooved channels 5-1 formed around the outer surfaces of the air chamber 5, preferably including the upper, lower and side surfaces thereof. The through-holes 4 and the grooved channels 5-1 are preferably overlaid as shown in FIGS. 1 and 2. Due to this grooved structures 5-1, combined with through-holes 4, the strength and air cushioning property of the air chamber 5 can be greatly enhanced.
  • According to one preferred embodiment of the present invention, the air chamber 5 is tightly and unitarily coupled with the sole member 6. As shown in FIGS. 2 and 3, the air chamber 5 is covered by and unitarily enclosed within the sole member 6 formed of suitable sole material such as polymer resins, except some external surfaces thereof. According to one preferred embodiment, the air chamber 5 formed according to the above described disclosure is located within a mold (not shown) of suitable configuration for forming the sole member 6, and a polymer or rubber material, for example, such as urethane resin, is filled within the mold and plasticized to form a sole shape. In this manner, the air chamber 5 is unitarily and securely covered by the sole member 6. As a result, the air chamber 5 is enclosed within the sole member 6 except the protruded side areas and rear area as shown in FIG. 5. The air valve 1, preferably along with the air conduit 2, is also exposed to the out side. However, it is noted that the grooved channel areas 5-1 and the through-holes 4 are covered by and filled with the sole member 6.
  • The air chamber 5 is formed of a resilient resin, rubber, or any other suitable elastic material with a sufficient strength and durability under a repeating and extended load condition. In one preferred embodiment, the air chamber 5 is formed of a polymer of a vinyl compound. The sole member 6 is formed of a resin, rubber, or any other suitable sole material. In order to allow the air chamber 5 to deform elastically, the enclosing sole member 6 should preferably be formed of a relatively resilient material, rather than a hard material.
  • Referring to FIGS. 4 and 5, the sole of the present invention may further comprise an outer sole member 13 attached at a bottom surface of the sole member 6. In one preferred embodiment, the outer sole member 13 has a property and quality for reducing slippage of the shoe sole relative to the ground. In another embodiment, the outer sole member 13 is formed of a material relatively harder than the sole member 6 to reinforce the sole or to provide an enhanced strength and durability to the shoe sole, and is also capable of reducing slippage as well.
  • The shoe sole member 6 may preferably include a plurality of cavities or grooves 6-1 disposed between the sole member and the outer sole 13. These cavities 6-1 can enhance the cushioning effects and provide comfortable feelings to the wearer of the shoe 12. The element 11 not described above depicts an upper 11 of the shoe 12.
  • As described above, the shoe 12 comprises a shoe sole which includes a partially exposed, elastic air chamber 5 and an exposed air valve 1. The air valve 1 is preferably an on-off control pneumatic valve for selectively controlling the valve between the on and off positions by the user. With the air valve 1, the wearer can adjust the air pressure of the air chamber 5 to a level of its choice. In order to increase the air pressure in the air chamber 5, the valve 1 is opened by the user and a compressed air is provided through the valve 1 into the air chamber. After reaching a desired level of the air pressure, the user can switch and leave the air valve 1 in a closed position, and the air of desired pressure is kept within the air chamber 5 and provides the cushioning effect to the shoe. Likewise, the wearer can freely adjust the air pressure level of the air chamber of the shoe sole, utilizing the externally exposed valve 1 and connecting to a source of compressed air. The manner of providing a compressed air is well known in the art. For example, it can be in the same manner to pressurize a pneumatic tire of an automobile by connecting a compressed air source, or can be in the same manner as pressurizing a tire of a bike through a manual pumping operation with a pneumatic pump.
  • As described above, the shoe sole of the present invention have a user-controllable air valve exposed externally, and thus, the wearer of the shoe can adjust a cushioning degree of the shoe by adjusting or controlling the externally-exposed air valve according to the user's desire or selection or in consideration of the user's weight. In addition, by having the shoe sole enclosing a substantially the entire outer surface of the air chamber, but leaving some of the outer surface thereof exposed externally, the appearance of the shoe may provide more artistic appeals to the wearers.
  • While preferred embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that many changes and modifications may be made without departing from the invention in its broader aspects. The appended claims are intended to cover, therefore, all such changes and modifications as fall within the true spirit and scope of the invention.
