Definitions

  • Common conventional shoe vamps have an inner layer of elastic foam rubber or sponge is added under an outer layer of leather, in order to produce comfortable and shock-absorbing function in wearing.
  • the inner layer of foam rubber has limits in its elasticity and the thickness of the layer so that the capacity of buf ⁇ fer and shock-absorbing for the conventional shoe vamps is not so ideal to meet practical use
  • this invention has been devised to offer a buffer double air cushion adaptable to a shoe vamp.
  • the main feature of the invention is an outer air cushion and an inner air cushion disposed in the outer air cushion, respectively having different inner pressure for forming a soft outer layer so as to give comfortable feeling and close fitting on a foot in wearing.

  • a buffer double air cushion in the present invention is to be adapted to a shoe vamp, so functions it should have are close fitting on a foot, and buffer and shock-absorbing function, not the same as that adapted to a shoe heel. Its thickness is rather thin, its upper surface has to be of a very similar curvature to a foot. In addition, the area surrounded by the peripheral hol- low edge is smaller than the surface area of the air cushion, permitting at least one surface or two surfaces have a swelled-up 3D arch shape.
  • Figs. 1 - 5 show a first preferred embodiment of a buffer double air cushion, which includes an outer air cushion 1, and at least one inner air cushion 2 disposed in the outer air cushion 1.
  • the outer air cushion 1 has a plurality of recess ⁇ ed holes 11 or recessed grooves 12 in an upper surface and/or a lower surface, but the recessed holes or the recessed grooves 12 may be omitted (as shown in Figs. 12 - 16). Further, the outer air cushion 1 has at least one side open for the inner air cushion 2 to be inserted and sealed up after the inner air cushion 2 is disposed therein.
  • the inner air cushion 2 to be disposed in the outer air cushion 1 has an inner pressure higher than that in the outer air cushion 1, and a plurality of recessed holes 21 or recessed grooves 22 formed in at least one surface or two surfaces.
  • the depth of the re- Completed holes 21 and the recessed grooves 22 is shorter than those 11 and 12 of the outer air cushion 1.
  • the width of the recessed holes 21 or the recessed grooves 22 is at least the same as the outer diameter or width of the holes 11 or the grooves 12 of the outer air cu- shion 1.
  • the inner air cushion 2 has a layer of glue or adhesive attached on an upper surface to adhere a contacting portion of an inner surface of the outer air cushion 1 when the inner air cushion 2 is disposed in the outer air cushion, with the open side of the outer air cushion 1 sealed up with heating. Then this doule air cushion has a single thickness but with two different inner pressures.
  • Figs. 6 - 9 show a second preferred embodiment of a buffer double air cushion in the present invention, wherein an outer air cushion 1 and an inner air cushion 2 are combined together, with recessed holes 11 or recessed grooves 12 of the outer air cushion 1 fitting in recessed holes 21 or recessed grooves 22 of the inner air cushion 2, and with those holes 12 and 21 or grooves 12 and 22 of both the air cushions 1 and 2 firmly engag ⁇ ing one another after the inner air cushion 2 is inflated with higher pressure than that of the outer air cushion 1.
  • the inner pressure of the outer air cushion 1 is effected by a hollow passageway 10 attached on the same cushion 1. Then the outer air cushion 1 is inflated through the passageway 10 after its peripheral edge is sealed up.
  • the inner air cushion 2 also has a hollow passageway 20 for filling a gas in its interior to a preset pressure.
  • the inner air cushion 2 inflated in advance is inserted in the outer air cushion 1, and then the outer air cushion 1 is sealed and inflated.
  • Another method of inflating different inner pressure in the outer and the inner air cushion 1 and 2 is shown in Fig. 11.
  • the hollow passageway 10 of the outer air cushion 1 and that 20 of the inner air cushion 2 are made coaxial. At first, the same pressure is in- flated in both the outer and the inner air cushion 1 and 2, and then the passageway 10 of the outer air cushion 1 is sealed up.
  • the inner pressure of both the outer and the inner air cushion 1 and 2 are the same because of the passageway 20 still open to permit the inner air cushion 2 communicate with the outer air cushion 1.
  • the outer air cushion 1 is compressed to force gas therein to flow into the inner air cushion 2 not compressed through the passageway 20, resulting in a higher pressure in the inner air cushion 2 than that in the outer air cushion 1.
  • the passageway 20 is sealed up with the passageway 10, finishing the process.
  • the finished buffer double air cushion has the outer air cushion 1 being soft owing to lower inner pre- sure than the inner air cushion 2, which is harder than the outer air cushion 1 owing to high inner pressure.
  • the inner pressure of the inner air cushion 2 is also of the same pressure, 20 lbs, as both the two air cushions 1 and 2 communicate with each other.
  • 10 lbs pressure of the outer air cushion 1 may be moved into the inner air cushion 2, with the pressure of the outer air cushion 1 becoming 10 lbs, and with the pressure of the inner air cushion 2 becoming 30 lbs.
  • the passageway 20 of the latter is sealed to keep the different pressure for the both 1 and 2.
  • the inner air cushion 2 when the buffer double air cushion is compressed, the inner air cushion 2 only receives 20 lbs pressure because the outer air cushion 1 have 10 lbs, with the original 30 lbs pressure of the inner one subtracted 10 lbs. Therefore, the whole structural load is not increased, but as to buffer and shock-absorbing effect, the outer layer of the double air cushion is soft and comfortable and the inner layer is a little harder than the outer layer with different buffer effect.
  • the buffer double air cushion has a special structure of different inner pressures, but with a single height, which has not yet been found in conventional air cushions.
  • the interior of both the inner and the outer air cushion 1 and 2 may be filled with air, a low-percolating large particle gas such as SF6, C2F6, etc., a fluid, a semi-fluid or a liquid.

Abstract

Cette invention se rapporte à un coussin d'air double, protecteur, qu'il est possible d'adapter à une empeigne de chaussure et qui comporte un coussin d'air externe (1) et un coussin d'air interne (2). Ces coussins d'air externe (1) et interne (2) sont gonflés à une pression interne différente. Ils sont pourvus chacun d'une surface supérieure incurvée vers le bas, des deux côtés, et dotée d'une courbure non spécifique. Ainsi, le coussin d'air double de protection possède une bonne courbure 3D qui peut s'adapter parfaitement au pied dans la chaussure, et il offre de ce fait une excellente caractéristique de protection et d'amortissement des chocs résultant de la pression d'air ou de gaz.
