Definitions
- This invention concerns a sneaker combinable with a replaceable male cushion fitting releasably in a female cushion formed integral with a sole.
- the male cushion has a plurality of projecting hollow cell bodies to fit and be inflated in chambers of the female cushion so that the inflated cell bodies may engage firmly with the chambers or corners of the female cushion of the sole.
- This invention has been created to offer a sneaker combinable with a replaceable male cushion to releasably fit in a female cushion formed integral with a sole of the sneaker.
- a feature of the invention is that the male cushion is independently made, and has a plurality of projecting hollow cell bodies and is able to be inflated after the male cushion is inserted in the female cushion of the sole, so the male cushion may be secured in the female cushion thereby giving the sneaker a good shock-absorbing function, and being replaceable in case of breakage.

- a combinable sneaker with a first preferred embodiment of a replaceable male cushion in the present invention includes a sole 1, a female cushion 2 formed integral in the sole 1, and a male cushion 3 fitting releasably in the female cushion 2.
- a first preferred embodiment of the female cushion 2 formed integral in the sole 1 shown in Figs. 1 - 4, has one or more elongate lengthwise hollow chambers 20 and one or more short transverse hollow chambers 21 in a heel portion which cross chamber 22, forming one or more corners 210.
- Each chamber 21 has a cross-section of any geometrical shape.
- Figs 7, 8 and 9 show a first preferred embodiment of a male cushion 3, which has almost the same size as the female cushion 2, releasably fitting in the female cushion 2 and having the same number of projecting hollow cell bodies 30 as the short transverse hollow chambers 21 of the female cushion 2.
- the male cushion 3 When the male cushion 3 is in a deflated condition, it can be fitted into the female cushion 2, with the projecting cell bodies 30 fitting in the short transverse chambers 21 of the female cushion 2 and abutting at the corners 210.
- the projecting portions of the cell bodies 30 can be expanded a little to engage the corners 210 in an unreleasable condition so that the male cushion 3 may be firmly secured in the female cushion 2.
- a hollow tube 32 with an air valve 31 is attached to the male cushion 3 for inflating it. Should the male cushion 3 become broken and deflated, it can be replaced with a new one.
- Figs. 10 and 11 show a second preferred embodiment of a female cushion 2 of a sole of a combinable sneaker, provided with one or more transverse hollow chambers 21, and at least one transverse hollow chamber 23 is of an unequal inner diameter from the rest of the chambers 21 and it has a larger cross-section in the middle portion of the sneaker the cross-section towards the sides of the sneaker.
- the chamber 23 of unequal inner diameter engages a projecting cell body of unequal outer diameter of a male cushion 3.
- Figs. 12 and 13 show the second male cushion 3 combined with the second female cushion 2 of the sole 1.
- the second preferred embodiment of the male cushion 3 is shown in Figs.
- a third preferred embodiment of a female cushion 2 is shown in Figs. 17, 18 and 19, formed separate and independent from the sole 1 and releasably combinable with the sole 1.
- the third female cushion 2 has a plurality of hollow three dimensional chambers 21 equidistantly arranged on the two lengthwise opposite sides to accommodate the same number of projecting cell bodies 30 of a third male cushion 3 to fit therein.
- the third female cushion 2 may be provided with recessed grooves or depressions 22 on an upper surface or a lower surface only, or on both of them, functioning as supporting ribs or posts after the male cushion 3 is fitted and inflated in the female cushion 2, prevented from disfiguring.
- the hollow three dimension chambers 21 of the third female cushion 2 have at least one chamber having a different dimension from the rest of the chambers, and one or more corners 210 are formed by a lengthwise chamber and one or more transverse chambers for the male cushion 3 to engage with.
- the male cushion can be filled with a gas, a fluid, semi-fluid, a liquid or a low percolating large particle gas such as SF2, C2F6, etc.
- the male cushion can be replaced with a new one any time.
- the projecting cell bodies of the male cushion having three-dimensional memory are easily inserted in the chambers of the female cushion in a deflated condition, and can easily be locked and secured after being inflated in the female cushion.
- the male cushion has a structure for easy assembly and replacement.
- the sneaker has a long service life because of the ability to replace the male cushion.
- the sneaker has high industrial worth and profitability.
