Description

A plurality of sport footwears that user's the pressure that pin produced had the insert of different elastic responses are housed

The present invention relates to a sport footwear that meets the preamble of main claim.

Sport footwear, comprise a sole spare especially for sport footwear as this type games such as race, basketball, tennis, vollyball, footrace, sole spare be furnished with vamp and can be divided into substantially two divide part very clearly, promptly contact and generally with the bottom of rubber or materials similar manufacturing or step on the end, ground and be placed on the top or the interior end above the bottom with ground.Make with sponge bullet colloid or its mixture such as vinyl acetate second fat or polyurethane usually at the interior end.

All require at least a portion of the sport footwear of the above-mentioned type can produce the user when it moves on its face impulsive force to return to the user for many years, lift and make this motion easier on pin so that help.

Remove outside the above-mentioned characteristic, the specific (special) requirements of this footwear at first is the position of pin when contact with ground of optimizing the user, is out of shape with the bone structure of the lower limb that prevent the user.To this, must add moving this requirement of natural order of the moving and outer transhipment of the interior transhipment of being convenient to the user.

Known the sport footwear that has all kinds to seek to satisfy above-mentioned requirements.Know that with the U.S. 5092060 and the U.S. 5369896 such type games footwear are arranged, it comprises a vamp, and a lower support part and that is used for above-mentioned vamp is located at the sole spare of this bottom.In sole spare, in the part corresponding of its position at least, an insert is set with user's heel, it comprises the airtight shell of the element that contains a plurality of elastically deformables, these elements are spaced-apart in uniform mode in fact.These elements have identical height basically and are barrel-shaped.The insert of aforementioned type has been adopted in the improvement of this structure, and it also is positioned at the corresponding part of metatarsal region sole spare and the pin user.The element of these elastically deformables connects together with the arm that is positioned at horizontal plane substantially and links to each other with the maximum cross section district of said elements.

Other shoes that the name of having known with the applicant forms the theme of different patents comprise the sole spare of a above-mentioned type, and it is provided with at least one insert with the element that inserts the elastically deformable in the airtight shell.These elements have different height so that shell in the face of above user's the pin spill being arranged, so that the pin to the user provides best stability when motion.

In these structures and in other structure of having known in present technique, the deformable element of various inserts (or those are located at sole spare) has uniform mechanical property.In other words, these elements are provided essentially identical elastic response by user's pin in the power that it is acted on during along ground motion to it.

Other layout of having known comprises a sole spare, and wherein the insert that is provided comprises and contains the air or the shell of the fluid of one or more kinds usually.This structure can make the response energy of various piece of insert according to they suffered power and variant when the user moves, and can make it the impulsive force that the user produces is on the ground obtained different shock absorbing characteristicses.But this structure is very expensive, and usually can not obtain the otherness response to the best of suffered power.

An object of the present invention is to provide a kind of sport footwear, it has compared improvement with known sport footwear.

A special purpose of the present invention provides a kind of sport footwear of the above-mentioned type, it has improved antisitic defect performance, it make the user particularly the sportsman security (sportsman is helped arduouser training) of raising is arranged in use, prevent the danger of possible contingency.In particular cases athletic, this can enable to obtain achievement preferably.

Another object of the present invention is for providing the sport footwear of the above-mentioned type, and the pin that it makes user balance again after it stops on the ground is so that improve its stability and reduce the energy that is consumed when controlled motion; So just obtain the efficient that improves.

Another purpose is for providing the sport footwear of aforementioned type, and its minimizing normally concentrates on the overload in pressure highest region territory in user's lower limb, thereby has strengthened the minimizing pressure thereon thus that head-on supports also of domain of dependence; The damage that is caused by overload is for example reduced by fracture or the muscle damage that this active force produces.

Another purpose is for providing the sport footwear of aforementioned type, it in light weight, reasonable price and pleasing outward appearance is arranged.

According to the described shoes of appended claims, can reach these and other objects very clearly all to the expert of present technique.

With reference to the accompanying drawings, the present invention will be clearer, and these figure provide as unrestricted example, wherein:

Fig. 1 is the schematic plan view according to the shoes of the present invention's formation;

Fig. 2 is the side view of the sole spare of Fig. 1;

Fig. 3 is the view similar to Fig. 1, shows an improvement of the present invention;

Fig. 4 is the perspective view of an embodiment of a part of the present invention.

With reference to above-mentioned accompanying drawing, sport footwear comprises vamp 1 and comprises the bottom (other parts such as wedge or shoe-pad, not shown) of sole spare 3.The latter comprises and is used for the bottom or the sole 4 that contact with ground that it is usually with rubber or similar material manufacturing.

What match on top at the end is an interior end 6 with stepping on therewith, and it is by playing colloid or playing the mixture of colloid such as vinyl acetate second fat or polyurethane are made.In the interior end 6, have at least a seat 8 that contains at least one insert of forming by airtight shell (containing fluid) 10 as the air (or have in as figure several be separated from each other), in shell, be provided with a plurality of usefulness and be positioned at the arm on same plane or the element 14 of the elastically deformable that bridge 13 connects together at least continuously.Among the embodiment shown in the figure, these inserts have occupied the whole seat 8 to the metatarsal region M of sole spare with the K district of the sole spare at user's heel place, have also occupied the corresponding sole area of pin vault (or vault district P) with the user.Another kind of scheme is if at K, M and P district several seats are set respectively, the insert of several correspondences to be set in these then.

But, even a district 8 only is set, but had better be in above-mentioned K, M and P district (as shown in the figure) place a plurality of inserts 10, they are represented with

reference number

10A, 10B, 10C, 10D, 10E in Fig. 1 and 3.

According to the present invention, the 14 pairs of plus-pressures of element (promptly to by user's effect extruding force thereon when its motion, race, the jump etc.) that are positioned at the elastically deformable of different sole area (K, M and P) show different responses.

Particularly, insert 10A and 10C in sole area K and M have high compressibility, and this K and M district require to provide maximum damping to the impulsive force that the pin by the user is produced on the ground.In contrast,

insert

10B and 10D are littler than above-mentioned compressibility, and insert 10E has the rigidity bigger than other insert.Its purpose is to reach the purpose of being stipulated for the footwear that form according to accompanying drawing by the present invention.

More more specifically, insert 10A is circular or is oval substantially.Its purpose is damping as much as possible or consumes the impulsive force that is produced on the ground by the heel that uses.This be because, this part of pin is rigidity substantially, itself can not the damping pin suffered impact when kiss the earth, especially when race, jumping etc.

Insert 10C flexible greater than other insert 10A Crumple element 14 and such shape is arranged, with the below of the metatarsal end of the activation person's of being used pin.

Otherwise insert 10B and 10D have, and as mentioned above, than the bigger Crumple element 14 of the rigidity of

insert

10A and 10C, and the element 14 of insert 10E has the rigidity rigidity also bigger than other insert.Should be pointed out that insert 10E can have different shapes according to the purposes that shoes are proposed.Under the situation of running shoes, it is especially at the side of the insert 10A (Fig. 3) of the medial side of heel, so as to control physiological in transhipment moving.This insert is led over the insert 10C of the metatarsal region M that is positioned at sole spare 3 towards the forward foot in a step, head-on provides supporting with the metatarsal to pin, with guarantee pin laterally before the stability of vault under load.Another kind of scheme is that insert 10E can be the circle (for example making the shape of a hoof) of part at least, thereby surrounds insert 10A.

Difference to the pressure of the element 14 of various inserts responds available different modes by changing its composition material, its shape and cross section or being reached by the long-pending selection of inner bottom surface that they occupy.

For example, can obtain bigger insert rigidity by the density that increases them.If they are to belong to poly-amion acetic acid second fat structure, then especially can be like this.Another kind of scheme is under the situation of solid polymer, can be formed for the element 14 of the insert of big rigidity with the polymer with bigger elastic modelling quantity.According to another kind of possibility, in order to obtain the bigger distortion of insert, its element can be made the little size of Crumple element 14 that the insert of moderate finite deformation is arranged than other requirement.

As for Crumple element 14, generally can form, so that its weight can alleviate with sponge bullet colloid (for example poly-amion acetic acid second fat).Otherwise, by adopting the bullet colloid of different-stiffness, then except the different inserts that have different compressible levels as mentioned above, can also for example obtain different compressible zones among 10A, B, C, D, the E at one and identical insert, progressively work so that sole spare responds the pressure of its zones of different.For example, this progressively property can be in insert 10B from obtaining during to metatarsal region M through heel area K.This is possible, particularly when insert (for example 10B or 10C) comprises along deformable element 14 that parallel not interconnected discharging is put.

Element 14 can make have circle, the rotary body of ellipse, polygon or other basal plane (for example star of Fig. 4), bucket etc., and weldering (for example by hot weld) is on the shell 11 that contains them.They arrange can resembling on the figure, make its longitudinal axis H perpendicular to sole spare 3 (or ground or they put plane), or are arranged in the relative shell, (not shown) in other two spatial axis that contain axis H.

This makes it and can arrange that the pressure to various sole area obtains different responses according to the space of the longitudinal axis of these elements.

If these elements are polygon (for example hexagon) or star (see figure 4), then they can be to providing remarkable response along any one pressure that obtains in two mutually perpendicular axis, and one in two axis is aforesaid longitudinal axis H.

Element 14 can be made solid (as among Fig. 1 to 3) or hollow (in Fig. 4).Under latter event, they also can contain fluid (as air, liquid or gas) inside, and they are in atmospheric pressure or are not under the atmospheric pressure.If fluid is the gas beyond the air, then it must be nontoxic and non-staining for example nitrogen, carbon dioxide, sulfur hexafluoride, argon etc.As for liquid, they must be inertia, nontoxic and preferably water-soluble, for example ethylene glycol, polyethylene glycol, the oil crossing fluorinated liquid (oil), polyester or oil product such as kerosene or use in vehicle motor.Also can use higher boiling alcohol.If adopt this liquid or gas, then element 14 obviously must not made by the material of the effect of these liquid with having low gas permeability, for example poly-amion acetic acid second fat of plasticity or polyester urethane thermoplastic resin.

At last, said elements 14 can be with different production technology manufacturings, for example injection moulding, extrude, blowing mould or vacuum forming.Said elements can be used as a string element of continuous placement and makes.This a string or row can be divided into after the element a plurality of for example as shown in the figure be placed on string among insert 10B and the 10C, they are parallel to each other substantially abreast.Another kind of scheme is, this string can be placed (as in insert 10A) by helical or along a circle or camber line or chine (as respectively in the

insert

10D and 10E of Fig. 3).But, other layout can belong to same inventive concept.For example, can reach its purpose in order to make the present invention, sole spare contains

element

10A and 10C, and this element can provide different responses at the pressure that its motion (as previously mentioned) produces to the pin by the user, and is just enough.In the drawings, have therein in other zone of sole spare of

insert

10C, 10D and 10E, insert can replace with traditional interior bottom material (vinyl acetate second fat etc.), add and resemble the element such usefulness rigidity of vault, arch and plate, that gently have highly elastic material such as composite to do, this composite comprises carbon fiber, glass fibre, aramid fiber (Kevlar) or polyester, or their combination etc.

In addition, one the Crumple element 14 of at least one insert 10A, B, C, D and E can be arranged in single plane or on several stacked levels.

These arrange the scope that also all is considered to belong to presents.
