Definitions

  • the present invention relates to a seif-inflatable air cushion for use in shoes, and more particularly to such a self- inflatable air cushion which comprises a collapsible plenum chamber, a support chamber, and an one-way valve connected between the plenum chamber and the support chamber for permitting air be driven from the collapsible plenum into the support chamber by compressing the plenum chamber with the foot.
  • a regular air cushion for shoes is generally comprised of a collapsible three-dimensional body defining a plurality of air cells and a plurality of passages connected between the air cells, and an air valve connected to the passages and disposed outside the sole of the shoe.
  • an air pump is attached to the air valve and operated to pump air into the air cells. If the inside pressure of the air cushion is excessively high, it cannot be regulated.
  • the self-inflatable air cushion comprises a support chamber, a collapsible plenum chamber surrounded by the support chamber and having an air hole, an air passage communicating between the support chamber and the collapsible plenum chamber, an one-way valve mounted in the air passage which permits air to pass from the plenum chamber to the support chamber.
  • a relief valve or pressure regulating chamber is provided to reguiate the inside pressure of the support chamber to the desired level.
  • a pressure accumulation chamber is provided having one end connected to the plenum chamber through an one-way valve, which permits air to flow from the pienum chamber to the pressure accumulation chamber, and an opposite end connected to the support chamber through an one-way valve, which permits air to flow from the pressure accumulation chamber to the support chamber.
  • Fig. 1 is an elevational view of a self-inflatable air cushion according to one embodiment of the present invention
  • Fig. 2 is an elevational view of a self-inflatable air cushion according to an alternate form of the present invention
  • Fig. 3 is an applied ⁇ ⁇ ew of the present invention, showing the self-ififlatable air cushion mourned in an insoie of a shoe and operated.
  • Fig 4 is a plain view showing another alternate form of the present invention.
  • Fig. 4 is a sectional view taken along line 10A- 10A of Figure 4;
  • Fig. 4B shows the turning direction of the plenum chamber of the embodiment shown m Figure 4;
  • Fig. 4C shows the plenum chamber of the embodiment of Figure 4 arranged in the top recess of the corresponding support chamber;
  • Fig. 4D is a sectional view taken along line 10D- 10D of
  • Fig. 5 is a sectional view of still another alternate form of the present invention, showing the installation of the pressure regulating rod in the pressure regulating chamber;
  • Fig. 5A is a sectional view taken along line 1 1A-11 .
  • a seif-inflatable air cushion la comprising a support chamber 1 , an open space 21 surrounded by the air chamber 1, a pienum chamber 10 disposed in the open space 21 and having an air hole 31.
  • an air cylinder 22 having its one end, namely, the rear end disposed in communication with the support chamber 1.
  • a connecting tube 33 connected between the plenum chamber 10 and the air cylinder 22, an one-way valve 101 mounted in the air cyl inder 22 which permits air to pass from the plenum chamber 10 through the air cylinder 22 to the inside of the support chamber 1 , and a relief valve 103 mounted in one end, namely, the front end of the air cylinder 22.
  • Figure 2 shows an alternate form of the present invention.
  • the air cushion 1 comprises a support chamber 1, an air cylinder 22 connected to the support chamber 1 at one side, a plenum chamber 10 spaced from the air cylinder 22 at one side opposite to the support chamber 1, and a connecting tube 34 connected between one end, namely, the rear end of the air cylinder 22 and the polonium chamber 10, an oneway valve 101 mounted in the air cylinder 22 for permitting air to be delivered from the plenum chamber 10 to the support chamber 1 , and a relief valve 103 mounted in one end. namely, the front end of the air cylinder 22.
  • the air cushion 1A is mounted inside an insole 6 of a shoe with the plenum chamber 10 projecting out of a top hole 61 of the insoie 6 at the heel area.
  • the plenum chamber 10 When the user's foot is stepped on the plenum chamber 10, the plenum chamber 10 is collapsed, and the inside pressure of the plenum chamber 10 is forced through the connecting tube 33 and the air cylinder 22 into the support chamber 1.
  • outside air is immediately drawn into the pienum chamber 10 due to an air pressure difference between the inside pressure of the plenum chamber 10 and the atmospheric pressure.
  • the support chamber 1 will be inflated to the saturated status.
  • the support chamber 1 supports the plenum chamber 10 against outside pressure. Further, through the relief valve 103, the user can adjust the pressure of the support chamber 1 to the desired level.
  • outside air passes from the air hole
  • the air hole 31 is stopped by the user's foot and the inside air of the plenum chamber 10 is forced by the pressure of the user's foot to flow through an air passage 3b to a pressure regulating chamber 301 and then through the aforesaid one-way valve 101 to a pressure accumulation chamber 6.
  • the pressure accumulation chamber 6 is arranged at a place in which the pressure accumulation chamber 6 bears no pressure when the support chamber 1 or the pienum chamber 10 receives a pressure from the user's foot, therefore, compressed air is allowed to be forced out of the plenum chamber 10 into the pressure accumulation chamber 6 and then through an one-way valve 102 into the support chamber 1 via an air passage 3a.
  • the plenum chamber 10 can be turned backwards through about 1 80° and arranged in a top recess 10a of the support chamber 1 with its air hole 31 facing upwards.
  • a pressure regulating rod Referring to Figures 5 and 5A.
  • the pressure regulating rod 301 is a hollow rod having a longitudinal center hole 52, a plurality of recessed holes 54, and a plurality of radial through holes 52 in communication with the longitudinal center hole 52.
  • the recessed holes 54 and the through holes 52 are arranged corresponding to distribution chambers 51, the oneway valve 101. and an air passage 3a.
  • the air cushion 1 A can also improve the ventilation of the shoe.
