Abstract
A self-inflatable air cushion (1a) which includes a support chamber (1) mounted in a sole (6) of a shoe and holding a liquid, a collapsible plenum chamber (10) surrounded by the support chamber (1) and partially protruding over the top of the sole (6) and having a top air hole (31), passage means (22, 33) connected between the support chamber (1) and the plenum chamber (10), and one-way valve (101) mounted in the passage means (22, 33) to let flow move in one direction from the plenum chamber (10) to the support chamber (1) upon compression of the plenum chamber (10).
Description
The present invention relates to be used for the interior self-inflatable air cushion of footwear, the self-inflatable air cushion that relates in particular to comprises an inflatable chamber that can flatten, a supporting cavity and a check valve that is connected between inflatable chamber and the supporting cavity, thereby when the pin compressing inflatable chamber, can make the air in the inflatable chamber that has flattened enter supporting cavity.
The inflatable air cushion that generally is used for shoes generally includes a crushable three-dimensional body and an air valve, and described body limits some gas circuits that are connected between each air chamber, and air valve links to each other with gas circuit, and this valve is arranged on the outside of sole.When putting into inflatable air cushion, air pump is connected on the air valve, and air pump is pressed onto in each air chamber.If the hypertonia in the inflatable air cushion, then this pressure can not be adjusted.
According to an aspect of the present invention, self-inflatable air cushion comprises a supporting cavity, one by supporting cavity round crushable inflatable chamber, one is connected between supporting cavity and the inflatable chamber so that make the gas circuit that they communicate, and the air that can make that is installed on the gas circuit enters check valve the supporting cavity from the inflatable chamber that flattens.When pin compressing inflatable chamber, force the air in the inflatable chamber of flattening to come out, behind check valve, enter supporting cavity.When unclamping the inflatable chamber of flattening, extraneous air sucks inflatable chamber through pore.According to a further aspect in the invention, provide a safety valve or a conditioning chamber that the air pressure in the supporting cavity is adjusted to desired level.According to another aspect of the invention, a pressure accumulation chamber is provided, one end in this pressure accumulation chamber links to each other with inflatable chamber by a check valve, this just can make the air in the inflatable chamber flow into the pressure accumulation chamber, the other end in this pressure accumulation chamber is linked to each other with supporting cavity by a check valve, just can make the air in the pressure accumulation chamber flow into supporting cavity.When inflatable chamber was pressurizeed, air flowed into the pressure accumulation chamber from inflatable chamber.Yet, because supporting cavity obtains external pressure simultaneously, so avoided the pressed gas in the pressure accumulation chamber to enter supporting cavity.During external pressure in discharging supporting cavity, the pressure air in the pressure accumulation chamber is flowed in the supporting cavity.

Referring now to Fig. 1,, shown self-inflatable air cushion 1a comprises a supporting cavity 1, a cavity 21 that surrounds by air cavity 1, the inflatable chamber with a hole 31 10 that is contained in the cavity 21, a gas column 22, one end of this gas column, the rear end that is to say this gas column is communicated with supporting cavity 1, a connecting pipe 33 that is connected between inflatable chamber 10 and the gas column 22, the air in the inflatable chamber 10 that can make that is installed on the gas column enters check valve 101 in the supporting cavity 1 through gas column 22, and an end that is contained in gas column 22, promptly be contained in the safety valve 103 of its front end.
Shown in Fig. 2 is another kind of form of the present invention.According to this modification, inflatable air cushion 1 comprises a supporting cavity 1, the gas column 22 that the one side links to each other with supporting cavity 1, in a side inflatable chamber 10 that separates with gas column 22 is arranged facing to supporting cavity 1, and one be connected an end (being the rear end) of gas column 22 and the connecting pipe 34 between the inflatable chamber 10, the air in the inflatable chamber 10 of can making that is installed in the gas column enters check valve 101 in the supporting cavity 1, and an end that is contained in gas column 22, promptly is contained in the safety valve 103 of its front end.
Referring now to Fig. 3,, the inflatable air cushion 1A that is contained in the heel place of sole 6 has an inflatable chamber 10 that protrudes in the apical pore 61 of sole 6.When user's pin stepped down on the inflatable chamber 10, inflatable chamber 10 was crushed, and forced the forced air in the inflatable chamber 10 to enter supporting cavity 1 by connecting pipe 33 and gas column 33.When user's pin when the inflatable chamber 10 that flattens is mentioned, because pressure in the inflatable chamber 10 and the pressure reduction between the atmospheric pressure directly suck in the inflatable chamber 10 extraneous air.When user's pin stepped down on the inflatable chamber 10 of inflatable air cushion 1A continuously, the pressure in the supporting cavity 1 can be elevated to saturation state.When the pressure in the supporting cavity 1 was very high, supporting cavity 1 helped inflatable chamber 10 to overcome external pressure.In addition, the user can be adjusted to the pressure in the supporting cavity 1 level that needs by safety valve 103.
Referring now to Fig. 4,, extraneous air enters inflatable chamber 10 from pore 31.When user's pin was exerted pressure to inflatable chamber 10, pore 31 was blocked by user's pin, utilizes the pressure of user's pin, forced inflatable chamber 10 interior cavity flows to cross gas circuit 3b and entered pressure regulating cavity 301, entered pressure accumulation chamber 6 by described check valve 101 then.When supporting cavity 1 or inflatable chamber 10 obtain by user's pin applied pressure, pressure accumulation chamber 6 should be in and make its place without undergoing pressure, so, at first force forced air to flow out inflatable chamber 10, enter pressure accumulation chamber 6, make air enter supporting cavity 1 by gas circuit 3a then through check valve 102.
Referring now to Fig. 4 B,, 4C and 4D, inflatable chamber 10 can rotate backward about 180 °, and this is contained in inflatable chamber among the top recess 10a of supporting cavity 1, and the pore 31 that makes inflatable chamber simultaneously up.
Referring now to Fig. 5 and 5A,, a pressure adjusting lever 301 is contained in the pressure regulating cavity 301.Pressure adjusting lever 301 is hollow stem, and this bar comprises: one in the hole 52 of longitudinal center, some recesses 54, and some radial direction through hole 52 that is communicated with longitudinal center hole 52.Recess of installing 54 and through hole 52 are corresponding to each distribution cavity 51, check valve 101 and gas circuit 3a.Regulate pressure in pressure accumulation chamber 6 and the supporting cavity 1 by rotation pressure adjusting rod 301.When through hole 52 was moved away gas circuit 3a, compressed air can not enter supporting cavity 1 from inflatable chamber 10.When gas circuit 3a, through hole 52 and distribution cavity 51 that when being interconnected by longitudinal center hole 53, compressed air flows into pressure accumulation chamber 6 according to the volume of distribution cavity 51.Suppose that the volume in the inflatable chamber 10 equals A, volume in the distribution cavity 51 equals B, then when inflatable chamber 10 flattens, its internal volume is C, so P1V1*P2V2=n, making the later pressure of inflatable chamber 10 pressurizeds is Pb=PaA/B+C, and therefore when the volume in the distribution cavity 51 was big more, the air pressure in the pressure accumulation chamber 6 was just more little.
When through hole 52 and inflatable chamber 10 were communicated with gas circuit 3c, air entered other regions of air circulation by gas circuit 3c after inflatable chamber 10 extrudes.So this inflatable air cushion ring can improve the ventilation effect of shoes.
Should be understood that only as describing, this does not limit scope described in the invention to accompanying drawing.
