The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further explained the present invention for better explaining.
The invention provides a kind of sole with good shock-absorbing function, and the footwear that adopt this shock-absorbing sole, comfortable and easy to wear, durable in use, be easy to make.A kind of shock-absorbing sole as shown in Fig. 1 a to Fig. 1 e and Fig. 2 a, comprises sole body 1, also comprises flexible tab 2, and described flexible tab 2 has a faying face 21.Described sole body 1 has the recess 3 that Open Side Down, hold a described flexible tab 2, and described recess 3 has an inner bottom surface 31; The faying face 21 of described flexible tab 2 by coordinating or be connected with the inner bottom surface 31 of described recess 3, such as bonding or the modes such as chimeric or engaging, with described sole body 1 combination, as shown in Fig. 2 a, can certainly be integrative-structure; Described faying face 21 can be the plane, can be also rough with the recess tabling of described sole body, the height of described flexible tab 2 is greater than the degree of depth of described recess 3, and namely to exceed described recess 3 outstanding downwards for described flexible tab 2, as shown in Fig. 1 a, Fig. 1 b, Fig. 1 c.Described flexible tab 2 is for having the hollow structure 23 of at least one perforate 22, as shown in Fig. 4 b.Described flexible tab 2 is for having the hollow structure 23 of at least one perforate 22.Described flexible tab 2 can with decorative pattern, as shown in Fig. 1 a, Fig. 2 b, Fig. 2 d, can certainly be not have dapple smooth structure, as shown in Fig. 1 a, 1b, 2e at the position that contacts with ground.
Described flexible tab 2 can be a plurality of flexible tab.A plurality of flexible tab can be that the triangle with rule, hexagon or other polygon as Fig. 1 a, 1b, 4a arranged arranging of sole body 1, make foot stressed more even; Can be also the longitudinal arrangement along sole body 1 lower surface as shown in Fig. 1 d, Fig. 1 e, such as one-tenth one is listed as or two row, or row, two be listed as the forms arrangement of making up.In a word, described flexible tab 2 can be regular, balanced in the arrangement of sole body 1 lower surface, in order to better disperse pressure.
In first embodiment of the present invention, described flexible tab 2 flexible tab adjacent with at least one is communicated with its described hollow structure 23 separately by described perforate 22 separately; As shown in Fig. 1 d, 1e, the perforate 22 that mutually pass through separately between flexible tab 2 this moment is communicated with, and the upside of flexible tab 2 and sole body 1 can stuffiness, and at this moment, described sole body 1 forms hermetically-sealed constructions with the hollow structure 23 of described flexible tab 2.At this moment, when sole was stressed, the gas by a plurality of flexible tab 2 inner sealings of interconnecting provided cushion effect, makes sole have good shock-absorbing function.An expansion of the present embodiment is: place damping air cushion 7 between the flexible tab 2 of a plurality of connections and sole body 1, described damping air cushion 7 inner sealings have gas (therefore also can be called air bag), when damping air cushion 7 is stressed because its internal gas can not leak, so can on average disperse suffered power by gas, thereby it is stressed to have alleviated foot, has excellent damping effect, and larger cushion effect and bounce is provided, make the user feel comfortable and easy to wear, be quick in action; Fig. 1 f is exactly the schematic diagram of the damping air cushion 7 that adapts of the shape of the flexible tab 2 of its shape and Fig. 1 e, between the flexible tab that is placed on Fig. 1 e 2 and its sole body 1 that this damping air cushion 7 just can be suitable; Described damping air cushion 7 can make the one body deformability with flexible tab 2 bondings, also can be non-caked, only rely on the cooperation cooperative transformation of both shapes.Certainly in the situation that a plurality of flexible tab 2 interconnect, also can between sole body 1 and described flexible tab 2, air-vent 4 be set sole body 1 is communicated with in order to ventilate with flexible tab 2.Described a plurality of flexible tab 2 can be structure as a whole; Can be also by bonding or engaging or chimeric connected mode, a plurality of independent flexible tab 2 to be connected.Described recess 3 can be a plurality of recesses.Described recess 3 can be communicated with by the recess 3 adjacent with at least one.That is, in the situation that a plurality of flexible tab 3 is interconnected, a plurality of recesses can be communicated with or not be communicated with, and whether a plurality of recesses are communicated with the sidewall whether link position that depends on a plurality of flexible tab needs to pass described recess.
In second embodiment of the present invention, described sole body 1 can be provided with the air-vent 4 that runs through described recess inner bottom surface 31 and sole body 1 upside, as shown in Fig. 2 a, described recess inner bottom surface 31 (can certainly be on the medial surface of recess) has at least one described air-vent 4; The described perforate of flexible tab 2 is communicated with described air-vent, and the perforate 22 of described flexible tab 2 is at its faying face 21 places.the inner bottom surface 31 of the faying face 21 (can be the plane) of described flexible tab 2 and described recess in conjunction with after, air in the hollow structure 23 of described flexible tab is communicated with the air on sole body 1 top, as shown in Fig. 4 b, contact with ground at sole like this, in compression process, because flexible tab 2 is compressed, thereby the air-vent 4 with the gas in hollow structure 23 by sole body 1 is pressed onto sole body 1 top, when the sole built on stilts, flexible tab 2 restores to the original state, in sole body 1 top air intake flexible tab 2, thereby reached the effect of ventilation.This specific embodiment makes flexible tab 2 be communicated with sole body 1 upside by its perforate 22 and air-vent 4, not only provides cushion effect to sole, and makes sole have simultaneously ventilative function.
Preferably, the minimum dimension of described flexible tab 2 horizontal directions is much larger than the diameter of described air-vent, as shown in Fig. 2 a.Described here namely the former is more than 3 times of the latter much larger than referring to the former at least greater than the latter more than 2 times, if such as the diameter of air-vent 4 is 5mm, flexible tab 2 minimum diameter in the horizontal direction is at least 15mm; If the diameter of air-vent 4 is 8mm, flexible tab 2 minimum diameter in the horizontal direction is at least 24mm, stressed in flexible tab 2 like this and when producing deformation, gas in flexible tab 2 can all not leak into the upside of sole body 1 by air-vent 4 quickly, but flow out slowly, compress or rebound with regard to there being enough air pressure that flexible tab 2 is slowed down like this, thereby play better the effect of damping, simultaneously gas is flowed, reach the function that damping is breathed freely again.
In each above-mentioned embodiment, the shape of described flexible tab 2 can be the shape that spheroid cuts remainder after a spherical crown, the higher primary school of the described spherical crown that is cut is in the length of spheroid half axis, the faying face 21 of described flexible tab 2 can be the plane, described plane is tangent plane, as shown in Fig. 2 e.Described perforate this moment is preferably on described faying face 21.Described flexible tab 2 can be also other shape, such as the horizontal cross-section is the rectangular cylinder that rectangle or fillet rectangle or at least one straight flange change camber line into, can also be that the horizontal cross-section is that triangle or fillet triangle or at least one straight flange change leg-of-mutton cylinder of camber line etc. into.
Above-mentioned spheroid can be positive spheroid (as shown in Figure 1a) or spheroid (as shown in Fig. 1 e) or fasten with separately the end combination spheroid (as shown in Fig. 2 e) that forms by two ball-crown bodies with identical end, and described plane 21 is perpendicular to the axis of described spheroid.For spheroid, described plane 21 can be perpendicular to major axis or the minor axis of spheroid, and described plane 21 can be as shown in Fig. 1 d, Fig. 1 e perpendicular to the situation of the minor axis of spheroid.
