Description

What have a removable convex air cushion can be in conjunction with sport footwear

Technical field

The present invention relates to a kind of sport footwear that can combine with a removable convex air cushion, this convex air cushion can pack into dividually with sole spill air cushion in aggregates in.This convex air cushion has a plurality of outstanding empty single chamber bodies and packs in the cavity of spill air cushion and inflation therein, and Chong Qi single chamber body will contact securely with the cavity or the bight of the spill air cushion of sole like this.

Background technology

The conventional sport footwear that has air cushion generally is provided with the air cushion of a given shape at footwear root place.Some sport footwears form an air cushion to play shockproof effect in footwear.This air cushion can not be too thick, so the gas that adds in the air cushion is also less relatively, actual damping effect is little.The air cushion that is arranged in the heel can have bigger space, so just has relatively large damping size.But air cushion often breaks, and owing to breaking of air cushion has to footwear are thrown away, does not also more renew the structure of air cushion in the footwear up to now, thereby causes waste.

Summary of the invention

The objective of the invention is to provide a kind of sport footwear that can combine with a removable convex air cushion, this convex air cushion can pack into dividually with sole all-in-one-piece spill air cushion in.

A feature of the present invention is that the convex air cushion is to make separately, and have a plurality of outstanding empty single chamber bodies, after in the spill air cushion of convex air cushion insertion sole, can inflate, the convex air cushion will be fixed in the spill air cushion like this, thereby make sport footwear have good shock-absorbing function, when breaking, can also change.

The specific embodiment

What as shown in Figure 1, have replaceable convex air cushion first preferred embodiment of the present invention can comprise that a sole 1, is integrally formed in a spill air cushion 2 and the convex air cushion 3 that can be contained in dividually in the spill air cushion 2 in the sole 1 in conjunction with sport footwear.

Be integrally formed in first preferred embodiment of the spill air cushion 2 in the sole 1 shown in Fig. 1-4, the transverse passageway 21 that has vertical cavity 20 and one or more weak points of one or more prolongations at the heel position, this cavity 21 forms one or more bights 210 across cavity 22.Each cavity 21 has the section of a random geometry.

Fig. 7,8 and 9 illustrates first preferred embodiment of convex air cushion 3, have and spill air cushion 2 size much at one, in the spill air cushion 2 of can packing into dividually, and have with the hyphen of spill air cushion 2 to the identical outstanding empty single chamber body 30 of cavity 21 quantity.When convex air cushion 3 was in deflated state, it can be packed in the spill air cushion 2, and outstanding single chamber body 30 is packed the hyphen of spill air cushion 2 in cavity 21, and the 210 places butt joint in the bight.In convex air cushion 3 insertion spill air cushions 2 and after the inflation, the ledge of single chamber body 30 will omit microdilatancy, engage with bight 210 under inseparable situation, and convex air cushion 3 can be securely fixed in the spill air cushion 2.In addition, a blank pipe 32 that has air valve 31 is connected on the convex air cushion 3, is used for inflation.If convex air cushion 3 breaks and dwindles, available new replacement.

Figure 10 and 11 illustrates can be in conjunction with second preferred embodiment of the spill air cushion 2 of athletic shoe sole, be provided with one or more transverse passageway 21, at least one transverse passageway 23 has and other cavity 21 unequal internal diameters, and has bigger section at the middle part of footwear, and this section is towards the sidepiece of footwear.Like this, the cavity 23 with unequal internal diameter engages with the outstanding single chamber body with unequal external diameter of convex air cushion 3.Figure 12 and 13 illustrates the second convex air cushion 3 that combines with the second spill air cushion of sole 1.Second preferred embodiment of convex air cushion 3 is shown among Figure 14,15 and 16, has outstanding empty single chamber body 30, the external diameter of wherein one or more outstanding single chamber bodies 30 is different with other single chamber body, after the second convex air cushion 3 inserts in the second spill air cushion 2, be securely fixed in the inside like this thereby can make it omit microdilatancy therein to its inflation.

Figure 17,18 and 19 shows the 3rd embodiment of spill air cushion 2, separates with sole 1 and shaping independently, and can combine dividually with sole 1.The 3rd spill air cushion 2 has the three-dimensional lumen 21 of a plurality of skies, and cavity 21 is equidistant to be arranged on two vertical opposite sides, with the outstanding single chamber body 30 of the 3rd convex air cushion 3 that holds equal number so that pack into wherein.In addition, the 3rd spill air cushion 2 can be only at upper surface or lower surface or groove or depression 22 are set on two surfaces, after convex air cushion 3 is installed and inflated, play the effect of supporting rib or bar in spill air cushion 2, to prevent distortion.The size of at least one is different from other cavity in the three-dimensional lumen 21 of the sky of the 3rd spill air cushion 2, forms one or more bights 210 by a vertical cavity and one or more transverse passageway, to engage with convex air cushion 3.

The convex air cushion can charge into gas, fluid, semifluid, liquid or hyposmosis bulky grain gas such as SF2, C2F6 etc.

The sports footwear that has replaceable convex air cushion among the present invention has following advantage:

1. the convex air cushion can be at any time with new replacement.

2. the outstanding single chamber body that has the convex air cushion of three-dimensional memory space is easy to insert in the cavity of spill air cushion in deflated state, is filled with air to be easy to locking and fixing in the spill air cushion, and the structure of convex air cushion is easy to install and change.

3. after the convex air cushion breaks, can be directly with new replacing, sport footwear can continue to use, and it is functional can not to reduce.

4. owing to the convertibility of convex air cushion, sport footwear has a long service life.

5. this sport footwear has high industrial value and can be profitable.

Above the preferred embodiments of the present invention are described, but should be familiar with and be understood that, wherein can carry out various modifications, appended claims will be carried out lid and be fallen into all interior this modifications of spirit and scope of the invention.
