Abstract

The utility model relates to an integral air bubble middle sole, belonging to a sole. When a heel and a vola corresponding to the middle sole are molded, air cells are formed at the positions of the heel and the vola, and the two air cells are communicated by an air passage. Simultaneously, the air volumes of the two air cells lie in the unsaturated state, and the air bubble middle sole is formed. The air bubble middle sole can be matched with the action of the trample of the foot. The inner air can circulate in the two air cells according to the change of the relationship between the heel and the vola, which provides the elastic wearing tactility.

Description

Integral air bubble middle sole

The utility model is the end in a kind of integral type bubble, belongs to sole.

Along with the footwear art progress, and in response to consumer demand, sport footwear is except appearance design, more pay attention to the function design of dress, and for providing sport footwear to have preferable elasticity and soft sense of touch, make to obtain comfortableness and security protection between doing in running, beating, being and generally making in the middle end of sport footwear is that the material that adopts elasticity preferable (as EVA etc.) is raw material, more has to install air cushion, gas bag or other elastomers additional in inside.

Be set forth in inside, the middle end in the past and installed elastomer preparings such as air cushion additional, generally only focus on the elasticity lifting at heel position and do single setting, though upward provide the heel position splendid elasticity in dress, but between trample action because of jump, running or walking, be not all to be the kenel that heel lands earlier, it is arranged at elastomer the design at heel position, when sole lands in advance (especially jump action), elasticity deficiency because of the sole position, Chang Yi causes the athletic injury at sole position, and still difficulty is called well designed.

Moreover the elastomer that preset inside, the middle end is an additional attachments, except that the increase that causes material cost, more has definite shape because of elastomer and is coated in the cladding material, and the elasticity that it provided just is restricted, and fails to provide best elastic effect.

In order to overcome the problem of above-mentioned existence, the purpose of this utility model is: a kind of setting of exempting the additional flexibility body is provided, and the end in the integral type bubble of wearing sense of touch more full of elasticity.

In order to realize above-mentioned purpose, the utility model is taked following technical scheme: the utility model is the end in a kind of integral type bubble, by forming at the middle end of hollow.Inner corresponding heel in the end and sole position are preset with former and later two air chambers in tying up to, and between 2 air chambers, connect with an air flue, and the gas of unsaturation state is housed in the 2 air chambers, can gas be circulated between 2 air chambers, and then formation is given the comfortable sense of touch of wearing with respect to the elastic reaction of foot.Gas is air or nitrogen.

The utility model compared with the prior art, its advantage: exempted the setting of additional flexibility body and annex, and changed, sense of touch comfortable and easy to wear more full of elasticity is provided to be air chamber in the lump in advance in inside, the middle end when the moulding.

The utility model can also obtain further instruction from the following drawings and embodiment:

Fig. 1 is the utility model stereoscopic schematic diagram.

Fig. 2 is the utility model structure cross-sectional schematic.

Fig. 3 is the structural relation schematic diagram of the utility model heelstrike the time.

Fig. 4 is the structural relation schematic diagram of the utility model when sole lands.

The drawing explanation:

The end among the 10-, 11, the 12-air chamber, 13-air flue, 14-pin.

Below by accompanying drawing embodiment of the present utility model is described in detail:

The utility model is the end in a kind of integral type bubble, particularly a kind of annex such as elastomer that do not add, and obtain the end in the better flexible bubble of wearing sense of touch.

See also illustrated in figures 1 and 2, the middle end 10 is to make with expanded material, be to be that inside, the middle ends 10 respectively is provided with an air chamber 11,12 corresponding to human foot's heel and sole position in its design, between two air chambers 11,12 and with an air flue 13, connect, and the air in this two air chamber 11,12 is to be in the unsaturation state, uses when wherein an air chamber is squeezed, and its inner air can enter in another air chamber through air flue 13, treat pressure release in after, gas refluxes in former air chamber through air flue 13 again; According to this, change, must produce elastic reaction, the comfortable sense of touch of wearing is provided with respect to foot's trample action by the circulation of air in two air chambers 11,12.

The inferior structural relation schematic diagram that sees also Fig. 3 and Fig. 4, when jumping, between the trample action of running or walking, along with the heel of pin 14 is different with sole kiss the earth state, its corresponding air chamber 11,12 is to present compression thereupon or inflate different kenels, when heel lands earlier, the air chamber 11 that is positioned at the heel corresponding position promptly is squeezed, its inner air is to flow into through air flue 13 in another air chamber 12 at sole position (as shown in Figure 3), and after sole lands, the air chamber 12 of corresponding sole is squeezed, be that gas is refluxed in the air chamber 11 at heel position (as shown in Figure 4) through air flue 13, by this, two air chambers 11 of the present utility model, the unsaturation state of 12 design and inner air, the end 10, can be trampled one of motion with foot and pressed one to put and produce and fill in the order, venting, suitable elasticity is provided, can forms preferable elastic tactility when pin 14 is worn, solve the problem that elastomer is derived that installs additional.

In sum, the utility model is by structural design, when the moulding of the middle end, form the integral type air chamber in its inside in the lump, make and cooperate the motion generation of trampling of foot to fill, exit, and then the comfortable flexibility sense of touch is provided, than now knowing modes such as installing air cushion or elastomer additional, also be better than now knowing mode on its elastic effect, not less than being an excellence, really be to be the innovative design of a uniqueness.

Claims

1, the end in a kind of integral type bubble, the middle end by hollow is formed, and it is characterized in that: inner corresponding heel in the end and sole position in tying up to are provided with former and later two air chambers (11), (12), and between 2 air chambers, connect with an air flue (13), and in the 2 air chambers (11), (12) gas is housed.

2, the end in the integral type bubble according to claim 1, it is characterized in that: gas is air or nitrogen.
