Description

Sport footwear with the shoe sole component that comprises at least one composite layer

The present invention relates to a kind of footwear, relate in particular to a kind of according to main claim sport footwear as described in the preamble.

It is fairly obvious that the feature of sport footwear changes recently.Particularly in recent years, tried hard to a kind of like this sport footwear of design, its can with the people in walking, run, jump or other motion process directly towards ground or the portion of energy of static surface effect be transmitted back on the wearer's foot.Therefore, attempt to realize that a large amount of deisgn product of this purpose is known, they comprise the elasticity insert that is configured in shoe sole component (being preferably in heel) inside usually.Though these known design products are realized satisfied result, there are various shortcomings in they.These shortcomings comprise: the overweight obvious problem that causes of footwear is that wearer (for example sportsman) is tired prematurely in the process of wearing, significant structural complexity causes the bad installation of shoe sole component and/or is positioned at the bad installation of its insert, thereby can not fully energy be transmitted back on wearer's the pin; The shape of the shoe-pad of shoe sole component or the location that is in contact with it does not meet the requirement of department of anatomy reason, thereby the wearer is felt bad.Therefore, may increase new problem, rubber soles absorbs moisture in the process of wearing, and particularly is stained with the earth on some wet grounds, and causing the obvious consequence for the wearer is that footwear further increase the weight of.

An object of the present invention is to provide a kind of footwear, particularly sport footwear, it is in light weight, delivers on the pin energy is counter when being raised after ground contacts at wearer's pin, and in fact do not absorb or seldom absorb moisture, and the pin that supports the wearer well.

Another object of the present invention provides a kind of footwear of the above-mentioned type, wears to make the wearer too tired, and can not be woven with any damage to bone and muscle groups.

Utilization is according to the footwear described in the dependent claims, particularly sport footwear, for person skilled in the art, clearly can realize these or other purpose.

According to the accompanying drawing that provides as infinite example, make and can more clearly understand the present invention, wherein:

Fig. 1 is the exploded view according to footwear of the present invention;

Fig. 2 is the bottom view of footwear shown in Figure 1;

Fig. 3 is the rearview of footwear shown in Figure 1;

Fig. 4 is the exploded view of the footwear of first kind of remodeling of the present invention;

Fig. 5 is the exploded view of the footwear of second kind of remodeling of the present invention.

With reference to Fig. 1,2 and 3, footwear 1 particularly sport footwear comprise vamp 2, shoe-pad 3 and shoe sole component 4.Shoe sole component 4 comprises: by composite braided material (promptly as in common fabric, comprise radial fiber T knit with weft fiber O be in the same place) first 5 or the sole portion of system; These fibers can be to be the fiber that the known materials (aromatic polyamides that floods with thermosetting resin) of Kevlar is made with the carbon fiber (or carbon resin) of thermosetting resin dipping and/or with trade mark.If carbon fiber is combined with aramid fibre, obtain a kind of carbon fiber that radially is, broadwise is the fabric of aromatic polyamides or (Kevlar fiber).Described radial fiber T (or weft fiber O) is parallel each other, all the angle (yet radial fiber and weft fiber quadrature) that becomes to be scheduled to the longitudinal axis X of footwear.With first's 5 relevant being associated with: the second portion 6 that position and wearer's the corresponding woven composite in arch vola is made, the third part made from the corresponding woven composite of position and wearer's metatarsal region 7 (as illustrated embodiment on figure, it covers the front end 8 of sole 1 and all parts between the part 6).Second portion 6 and third part 7 define second sole element that is made of composite 55.First comprises the flange 5A and the 5B of side.

More particularly, in the example shown in Fig. 1,2 and 3, sole element 5 and 55 links together, and the configuration that crosses one another of their fiber (carbon or aromatic polyamides or like fibrous) of first 5 and second portion 6 is so that corresponding sole element has sizable torsional rigidity.In other words, the radial fiber T in a part (for example part 5) disposes according to different space angles with the radial fiber T ' and the weft fiber O ' of second portion 6 with weft fiber O.For example, fiber T presses 45 ° of location with respect to the longitudinal axis X of sole element, and fiber T ' presses 90 ° of location to described axis X.Particularly the part 5 in the arch plantar region overlaps on the part 6, forms antitorque very firm assembly.Arch vola part also has the rigidity of bending resistance.

The composition fiber of part 7 (radial fiber T 〃 and weft fiber O 〃) is respectively according to single direction configuration, this orientation is such, all that promptly appear at this part radially with weft fiber along the configuration parallel to each other respectively of predetermined direction in space, or for axis X all respectively according to predetermined angle (they are each other still by 90 ° of configurations).The fiber T 〃 of part 7 and the orientation of O 〃 are parallel to the respective fiber T and the O of sole element 5, occur the part of the element 5 cooperate with part 7 at least.The single-orientated fiber of part 7 and corresponding sole element 5 (make radial fiber T and T 〃 and weft fiber O and O 〃 parallel to each other) provides pliability for sole metatarsal part (in the direction of arrow F), even combine with part 5 when part 7, so that this part can be born center on and the vertical curve (this axis W is located between the end 8 and part 6 of footwear) of the axis X that the longitudinal axis X of footwear is perpendicular.

Because the radial fiber of this part 5 (or claiming sole element 5) and the specific single-orientated configuration mode of weft fiber, it always has the limited pliability of self.

According to footwear of the present invention, the bottom of shoe sole component is divided into 3 zones of (see figure 2), i.e. metatarsal region 7A (corresponding to part 7), arch plantar region 6A (corresponding to part 6) and heel region 10.Preferably metatarsal region 7A and heel region 10 usefulness rubber layers 11 and 12 cover, and this rubber layer 11 and 12 for example utilizes bonding agent or similar fixed form to be fixed on part 5 and 7.

Best, corresponding to heel region 10, part 5 comprises the part 13 on recessed bottom to footwear (promptly towards ground).Recessed portion 13 plays spring element, and its configuration makes and will be delivered to the anti-wearer of delivering to of a part of energy on the ground in the process of wearer's motion.Realize that this point does not need any additional elastomer (for example in the present technique field known those) is embedded in the footwear 1, this elastic system is used as the anti-element of delivering on the wearer's foot of energy.

In the process of wearing, shoe sole component according to the present invention has enough rigidity, very good support wearer's pin in the process of wearer's motion.Yet, because metatarsal region 7A has enough pliabilities, shoe sole component has suitable " yieldability ", its degree can not produce adverse influence to the bone and the musculature of wearer's pin, thereby prevent micro-fracture, this micro-fracture may be very harmful, if particularly the wearer is an athletic word.In addition, has pliability by the end 8 regional 7A that 6 parts of extending 7 cover to the zone from footwear, make it can be used as such element, in order to returning towards the amount of the maximum possible of ground energy delivered by the wearer in wearer's motion process, so that produce sizable thrust (this is very favourable to for example sports events such as track and field and basketball aspect).This effect is on being attached to part 13 time, makes in the process of wearer's motion on the anti-wearer of delivering to of sizable energy.

According to first kind of modification of the present invention as shown in FIG. 1, by part 6 to extend an elongator 17 with its coplane form.This elongator 17 (or tongue) preferably is made of the composite of braiding, the radial fiber that comprises is orientated in the mode identical with the counterpart of part 5 and parallel with them (promptly single-orientated) with weft fiber, and this elongator 17 pierces in the corresponding groove seat 18 in rubber layer 12.This embodiment can increase the stability of footwear 1, therefore, correctly supports wearer's pin on the ground.

The another kind of modification of expression among Fig. 4 is wherein utilized and identical is represented and the corresponding part of introductory section with reference to label.In embodiment as shown in the figure as an example, part 5 (only utilizing its warp fiber T schematically to represent) is not connected on any part that other is made of woven composite, but opposite with counterpart 5 among Fig. 1, it comprises: the individual layer metatarsal part 5E that single-orientated fiber (by above-mentioned connotation) constitutes and with the corresponding part 5F that comprises at least two overlapping layers of arch foot.Every layer comprises warp-wise and the weft fiber that the mode by common of controlling oneself weaves.Yet this two-layer warp-wise (or broadwise) fiber becomes different angles for axis X, thereby limits the integral part 5F that is made of the fiber that intersects.Corresponding with the part 10 of wearer's heel or sole assembly, part 5 or sole element 5 comprise by one deck braided fiber as the composite of 5E, and comprise the annular lip 40 (is flexible as part 5E) of extending along the neighboring in described zone.In this manner, zone 10 can also hold an elasticity insert 41, gives the wearer so that can it be delivered to the portion of energy loopback on ground in wearer's motion process.This insert is known type (for example introducing in US5369896 or US509206), thereby no longer further introduces.Specifically, insert 41 can be contained in the groove seat 42 that is located in the part 5 (by flange 40 gauges), and/or in heel area 10 and the rubber layer 12 that part 5 is associated in the groove seat 43.If need, insert 41A can also be embedded among the groove seat 42A set in the metatarsal region of part 5 (or sole element 5), and/or be located among the groove seat 43A in the layer 12.Insert 41A has the feature identical or equivalent with insert 41.

Embodiment among Fig. 4 has increased the stability of footwear 1, therefore correctly supports wearer's pin on the ground.At this on the one hand, sole element 5 has antitorque rigidity in the regional 6A of shoe sole component, is flexible at regional 7A around axis W.

In the modification in Fig. 5, profit is denoted by like references and the corresponding part of part of by the agency of, part 5 (among Fig. 1 similar) only comprises the regional 6A and the 7A of shoe sole component, does not comprise the former composite layer (being carbon containing, aromatic polyamides or other fiber) that appears in the zone 10.In the modification as example, shoe sole component also comprises the bottom rubber element 50 that spreads all over whole shoe sole component 4.This embodiment as example reduces the manufacturing cost of footwear 1.

At another only among the embodiment as example, (therefore shoe sole component 4 can also only comprise the direct part 6 and 7 that is associated with shoe-pad 3, do not comprise the part 5 shown in Fig. 1 and Fig. 5), part 6 comprises two-layer fabrics, and warp-wise of one deck and broadwise and axis X form warp-wise and the broadwise that the space gradient is different from another layer.

Above by the agency of various modification of the present invention.All comprise shoe sole component 4, it is made up of following part at least: comprise two laps being made up of the flexible fiber of composite (carbon, aromatic polyamides, the combination of carbon one aromatic polyamides or other material) at least, the footwear longitudinal axis is by the warp-wise and the weft fiber of the first of first gradient relatively, and described relatively axis is by the warp-wise and the weft fiber of the second portion of different gradients, and therefore the described fiber of first and second parts intersects; And by the part 7 of braiding synthetic material or the metatarsal region 7A (i.e. sole area between regional 6A and sole end 8) that 5E limits, its warp-wise and weft fiber all have the same tilt degree with respect to the footwear longitudinal axis, and therefore described fiber is single-orientated.To this its reason is in order to obtain a kind of like this shoe sole component, and itself and the corresponding part in arch vola are rigidity, are flexible forward, keep required torsional rigidity simultaneously.Because described each several part also can connect sole element 5, this element 5 is made of the woven composite with warp fiber and weft fiber, these fibers have different gradients with the counterpart of the part 6 that is located at part 6A inside, arch vola, but have identical gradient with the fiber of this part that appears at metatarsal region 7A inside.

According to another embodiment of the present invention, part 5,6 and 7 or 6 and 7 or only 5 (as shown in FIG. 4) are not to be made of the composite that comprises fibre composition, and part 5,6 and 7 or 6 and 7 or only 5 is to be made of the composite according to known technology hot pressing.Particularly, in this embodiment, obtain inflexibility by heat pressing operation with torsional rigidity district (for example 6A), this operation comprise with carbon, aromatic polyamides or like powder pressurization utilize associated resin carry out in conjunction with the time wherein at least one step, this specified pressure is different from the pressure that powder is subjected to when being used to form regional 7A, and regional 7A is flexible around above-mentioned axis W.Reason to this is in order to obtain the required pliability of this regional 7A layer.

In addition,, have different thickness, obtain the different sole element or the different performance (flexibility or rigidity) partly that constitute by the composite that weaves by making these elements according to the different mechanical performance requirement of sole element.So just guarantee pliability that the metatarsal region 7A of shoe sole component is required and the rigidity of arch district 6A.

If part or layer 5,6 and 7 obtain according to mode shown in the accompanying drawing, can constitute footwear according to following step, be about to vamp and take off from shoe tree, the shape of this shoe tree is fit to the mean parameter of wearer's foot or aims at footwear design that sportsman (or general wearer) makes.Known bulk material (EVA is ethyl-vinyl acetate as is well known) or polyurethane or low-density rubber layer are configured in the sole portion of this shoe tree, to form shoe-pad 3, after this, will combine with this one deck by the previous one or more sole element that are shaped of composite.In these sole element each all is by utilizing for example epoxy resin impregnated woven composite of resin to form by injection molding in the former of the sole shape with described footwear.In this manner, obtain the preliminary working goods of sole, cut according to the size of described pin then.

Best, after constituting described preliminary working goods, on one of them (promptly being fixed on the rubber layer of shoe sole component) at least of two opposite surfaces, stick the fabric of the identical resin dipping of using with infused composite.According to the character of fabric, make this fabric have tangible surface roughness.

To be placed on according to the still preliminary working goods on shoe tree that this sample loading mode obtains then in the case of a formation vacuum.This case is placed a hyperbaric environment far above atmospheric pressure (for example 8 to 15 crust) together with the dress thing.By these operations, originally (utilize vacuum) and make composite layer to present the shape of pin sole, (utilize pressure) then by will appear between the described fiber or on excess resin by extruding in this one deck, it is highly closely knit that this fibrage is become.This is operating as the back composite layer and for example provides pliability around the axis vertical with the longitudinal axis of sole.

Then the sole element that will be shaped in this manner (by taking out in the case) (5-7 crust) under high relatively temperature (above 100-120 ℃) and the environment at relatively high pressure is carried out drying, continues the long relatively time (between 8 to 14 hours).Described baking temperature, pressure of living in are to select according to the thickness of employed composite and sole element together with the described time.

After this handled, the burr of removing on the sole element separated the fabric related with it with being gone up by its surface.Because this fabric has certain roughness, on described surface, keep very little gravure, the glue of other parts (rubber element or vamp) that makes it possible to utilize this to be used for sole element is fixed to footwear is fixing preferably.Then sole element is fixed on these elements by gluing.

Be surprised to find, the double-sided adhesive band that is used for fixing described footwear element can make the adhesives between each contact element distribute more equably, thereby has improved switching performance.

The sole element that obtains in this manner meets the dissection principle, thereby meets wearer's pin shape.

At last, when on other element that sole element (or sole element 5 and 55) is fixed to footwear, can be positioned in the sole element being used for being delivered to the anti-elasticity insert of delivering on the pin of ground energy by the wearer at people's motion process.

Because this ad hoc approach is used for composite part 5 (or 6 and 7) is fixed to shoe-pad 3, make this material according to the sole of wearer's foot (specific or average) shaping.Part 5 (or sole element 5) (if or this part do not appear as the layer 6 and 7) thereby the comfort (comprising the one or more additional shoe-pad that is located between shoe-pad 3 and the wearer's foot) that meets the shape of dissecting principle and improved footwear is arranged, safer for the wearer, its degree can prevent since the special long-term use of specific sports or footwear to cause that foot muscles is subjected to possible slightly injured.

In light weight according to footwear of the present invention 1, can not make wearer's fatigue.In addition, counter the delivering on the wearer's foot of energy on ground will be delivered to by best mode in the motion process by the wearer.Even without in addition elastic component (being suitable for this purpose) being embedded in the shoe sole component 4 and also can realizing this point.

In addition, can specific sports project for example football or the element commonly used of dash or each composite layer that the nail post bonds to footwear 1 simply will be used for, if do not carry out bonding operation (for example utilizing epoxy resin to realize), then can cause described element or nail post to come off at any time.Therefore, no longer need to be used for the mold pressing that described element or nail post combine with the shoe sole component that has rubber or similar material system is operated.

In addition, compare with known configuration mode, the rubber layer (one layer or more) that combines with each part of composite (braided fiber or hot-pressed material) can reduce significantly, thereby can reduce the absorption (also having earth) (this moisture can not absorbed by composite layer) of moisture when the wearer is movable on the ground.Thereby the weight that is reduced in footwear in the process of wearing significantly increases.

By the agency of various embodiment of the present invention.Yet can provide the sport footwear or the sneakers (for example a kind of layer 5,6 and 7 wherein is local hot pressing, and part is the composite based on fiber) of other form.In detail, shoe sole component can have difform composite insert for the footwear 1 that are used for the different motion project.For example, part 7 can only partly comprise the regional 7A of shoe sole component.In first embodiment, the shaping of this part has intermediate groove and extends as far as the end 8 of footwear near the side flanges at the edge of shoe sole component.In a second embodiment, these flanges only extend to outside the axis W of regional 7A on a small quantity.Therefore that is be that the physical training project of being engaged in according to him is selected these different embodiment wish that according to the sportsman speed that reaches.

Equally, part 6 can be straight (for example being used for sports and competitions and marathon footwear), it can be arc (for example be used for training) or can comprise some side direction reinforcements, their flange 5A and 5B on the part 5, the degree of overlapping extension is changeable (anti-twisting property of footwear is improved).

At last, in zone 10, part 5 (maybe may also have elongator 17) can be dove-tail, the effect of changeing in preventing with realization, and vibration damping and the stability of improving footwear.

These remodeling of being considered (or theirs is comprehensive) all fall within the scope of the present invention.
