Abstract

A buffer double air cushion adaptable to a shoe vamp includes an outer air cushion and an inner air cushion. The outer air cushion and the inner air cushion are inflated to a different inner pressure. An upper surface of both the outer and inner air cushion are curved down to two sides with non-specific curvature. So the buffer double air cushion bhas a good 3D curvature to closely fit a foot wearing it, and excellent buffer and shock-absorbing function by means of air or gas pressure.

Description

Buffer double air cushion

Background of the present invention

In order when wearing, to produce function comfortable and damping, traditional shoes sticking patch of common flexible foam rubber or sponge internal layer be added on leather outer field below.In fact, the foam rubber internal layer thickness that is limited to elasticity and layer causes the buffering of traditional shoes sticking patch and cushioning ability not really desirable in actual use.

A kind of inflatable pneumatic mattress that is used for the shoes sticking patch is disclosed by the same applicant of the present invention, but only to be a kind of 2D structure can not produce desirable shock-absorbing function for it.

General introduction of the present invention

Consider the shortcoming of traditional shoes sticking patch air cushion, the invention provides a kind of buffer double air cushion that is applicable to the shoes sticking patch.

The present invention is characterized in that an outside air cushion and is configured in the inside air cushion in the outside air cushion, they each have different internal pressures to form a soft outer layer, in order to produce comfortable sensation and close closely with hem facing when wearing.

The specific descriptions of most preferred embodiment

Buffer double air cushion of the present invention is applicable to the shoes sticking patch, thereby the function that it had is to fit tightly pin, and buffering and shock-absorbing function are different with the pad that is used for sole.Its thickness is quite thin, and upper surface has a radian similar to pin.In addition, by area that hollow periphery surrounded surface area, allow at least one face or two faces to have the 3D of a protuberance arc less than air cushion.Fig. 1-5 has shown first most preferred embodiment of buffer double air cushion, and it comprises an outer air cushion 1 and at least one the interior air cushion 2 that is disposed in the outer air cushion 1.

In outer air cushion 1 upper surface and/or the low slightly surface many shrinkage pools 11 or groove 12 are arranged, but shrinkage pool or groove 12 can be omitted (shown in Figure 12-16).In addition, outer air cushion 1 has at least one to be used for the side opening that interior air cushion 2 is inserted into, and it is configured in wherein back by involution at interior air cushion 2.

Be configured in interior air cushion 2 in the outer air cushion 1 and have one than the higher internal pressure of the pressure in the outer air cushion 1 and many shrinkage pool 21 or grooves 22 that on a surface or two surfaces, forms at least.The degree of depth of shrinkage pool 21 and groove 22 is less than the degree of depth of the shrinkage pool 11 and the groove 12 of outer air cushion 1.The width of shrinkage pool 21 or groove 22 equates with the shrinkage pool 11 of outer air cushion 1 or the overall diameter or the width of groove 12 at least.

In addition, in the air cushion time, interior air cushion 2 has one deck to invest the adhesive or the adhesive of upper surface outside interior air cushion 2 is configured in, and to adhere to the contact site of outer air cushion 1 inner surface, the open side of outer subsequently air cushion 1 is heat-sealed closes.So this double thickness air filled mattress has a thickness but two different internal pressures is arranged.

Fig. 6-9 shows second most preferred embodiment of buffer double air cushion of the present invention, its China and foreign countries' air cushion 1 and interior air cushion 2 combine, the shrinkage pool 11 of outer air cushion 1 or groove 12 are contained in the shrinkage pool 21 or groove 22 of interior air cushion 2, after interior air cushion 2 is used the pressure inflatable higher than outer air cushion 1, the hole 12 of air cushion 1 and

air cushion

2 and 21 or groove 12 and 22 combine closely each other.

The internal pressure of outer air cushion 1 is fixed in the influence of the hollow channel 10 on this air cushion 1.Outer air cushion 1 is inflated by path 10 after its periphery is by involution.Interior air cushion 2 also has a hollow channel 20 in order in inner filling gas to one predetermined pressure.In the real process, the interior air cushion inflated in advance 2 inserts in the outer air cushion 1, and outer then air cushion 1 is inflated by involution.

Fill in air cushion 1 and the interior air cushion 2 outside as shown in figure 11 with the another kind of method of different internal pressure gases.The hollow channel 10 of outer air cushion 1 and the hollow channel 20 of interior air cushion 2 are made into coaxial.At first, fill with identical pressure in air cushion 1 and the interior air cushion 2 outside, then, the path 10 of outer air cushion 1 is by involution.In this case, the internal pressure of outer air cushion 1 and interior air cushion 2 is identical, allows interior air cushion 2 and outer air cushion 1 intercommunication because passage 20 is still opened.Then, outer air cushion 1 is compressed the gas that forces in it and flows in the not compressed interior air cushion 2 through passage 20, produces than higher pressure in the outer air cushion 1 in the air cushion 2 in causing.Subsequently, passage 20 and path 10 involution have been finished whole process together.

The buffer double air cushion of completion has soft outer air cushion 1, and it has the internal pressure lower than interior air cushion 2, and it is harder that interior air cushion 2 has the outer air cushion 1 of higher built-in pressure ratio.At first when outer air cushion 1 during 20 pounds of interior pressures by involution, the internal pressure of interior air cushion 2 also is 20 pounds of same force value, because two

air cushions

1 and 2 communicate with each other.If so outer air cushion 1 is compressed, the inner surface of oppressing it contacts with the upper surface of interior air cushion 2, and in the air cushion 2, so the pressure of outer air cushion 1 becomes 10 pounds, and the pressure of interior air cushion 2 became 30 pounds in 10 pounds of pressure of outer air cushion 1 can enter.Then the latter's passage 20 by involution to keep different pressure in the

air cushion

1 and 2.

But when buffer double air cushion was compressed, interior air cushion 2 only held 20 pounds pressure, because outer air cushion 1 has 10 pounds of pressure, 30 pounds of original pressure of interior air cushion have been deducted 10 pounds.Therefore, the load of total does not increase, but in order to cushion the effect with damping, the skin of double thickness air filled mattress is soft and comfortable, and for different buffering effect internal layers harder slightly than skin.

Thereby buffer double air cushion has different internal pressures but the unique texture of single height, and this structure is also found in traditional air cushion.In addition, inside and

outside air cushion

1 and 2 inside all can be filled with air, and the gas of the big particle of hypotonicity is such as SF6, C2F6 etc., fluid, semifluid or liquid.

Most preferred embodiment of the present invention above describing, can be familiar with and be understood so, can make different modification, and subsidiary claim attempts to cover all modification, and it all will fall in the spirit and scope of the present invention.
