Description

Footwear and method for making thereof

The present invention relates generally to the boots class, and relates more specifically to walking and other movable boots construction of footwear of going up use.The present invention has special effectiveness to high-heeled shoes, though also considered other application, can specifically describe the present invention in conjunction with high-heeled shoes.

The evaluation of the high-heeled shoes that technology previous and use at present is made is extremely uncomfortable, and investigation points out that traditional high-heeled shoes user of 20% had because of wearing this shoes and can feel the experience of pin pain at once, and most user can feel that within four hours pin bitterly.The slippage forward and cause wearer's toe to be extruded in footwear of this uncomfortable pin mainly due to the wearer at the front end of shoes.

With reference to figure 1, be presented at the bony structure of a pin in the traditional high-heeled shoes among the figure with chain-dotted line.The structure of pin comprises calcaneum 10 (being also referred to as shank), arch area and phalanges or phalanx 13, and calcaneum 10 comprises astragalus and calcaneum, and arch area comprises ancient festival in spring and autumn held on water banks to drink and cleanse away the evil influences shape bone 11 and metatarsal 12.Entreat the spherical bone 16 of sole reinforcing section 15 to the substrate junction of pin metatarsal and phalanx 13 among in the arch area extend through footwear of pin, calcaneum 10 is supported by heel seat 19.The spherical bone of pin is below the metatarsal front end and form metatarsal, and phalanx is supported by shoes toe areas 9.

Show that in Fig. 1 these footwear have about 2 inches height of following.Shown shoes are according to No. 7, Unite States Standard women's shoes.Footwear are placed on the

basal plane

18, and 19 have with high through measurement and to be " a " from basal plane 18 to heel seat.Heel seat 19 is about 12-15 degree with respect to the acclivitous angle of basal plane.This angle " X " can be referring to Fig. 1 and Fig. 3.Central authorities' sole reinforcing section 15 is with forward and downward with respect to the angle inclination of about 30 degree of basal plane in footwear from shoe.This angle " Y " can be referring to Fig. 1 and Fig. 3.Big female toe of toe portion should be parallel with basal plane in footwear, but may because of toe portion have one with respect to basal plane 18 upwards and forward the angle of 2-3 degree cause it upwards and turn forward.This angle " Z " can be referring to Fig. 1 and Fig. 3.

Will be appreciated that one of be presented among Fig. 1 only traditional high-heeled shoes and make wearer's pin place a clinoplain substantially, therefore pin is forced to be forwarded to the toe casket when standing or walk.So cause constriction and toe extruding, often make this part pin produce a kind of sensation of burn, reach tired and uncomfortable at spherical bone or pin leading section branch.

Traditionally, shoes promptly slide with two kinds of basic technologies and go up one of them making of footwear (board lasting) on footwear (slip lasting) and the plate.Footwear are typically to be stitched together then sticking or to be sewn on central sole and/or the outsole with a upper of a shoe in the slip.Footwear are to stick or be sewn on a plane or the pre-template with upper of a shoe on the plate, then stick on sole and/or the outsole again.For footwear being collapsed and suitably supporting wearer's body weight, a reinforcement is commonly referred to as the sole stage casing, typically makes with metal, leather, fiberboard or plastics, is clinged and/or be sewn to central sole and/or insole plate and outsole.Some footwear structure also uses the shoe-pad lining of a mold pressing, and/or insole pad in footwear as the beam of pin.Though originally beam has comfortable sensation by pin in footwear, in fact beam destroys the biological engineering character of footwear, and to pin in footwear stability or all do not have to act on the tram feet of anatomy.

The present invention's main purpose provides a kind of footwear structure comfortable and easy to wear, also makes wearer's pin be in the correct Support Position of anatomy in footwear simultaneously.

Another object of the present invention is provides a kind of manufacturing method of shoes, and its footwear structure that provides is comfortable and easy to wear, also makes wearer's pin be in Support Position correct on the anatomy in footwear.

Another object of the present invention is provides a kind of device that changes heel with respect to the angle of inclination of basal plane, this device when the women wears high heels, be applicable to various height heels during with high the change and keep heel with basal plane near parallel relation.

Another object of the present invention is provides a kind of footwear structure, and it can support the Y of pin, but can make inclined shaft to flexibility is arranged.It will can be applicable in the design of golf shoes for example, and it can have flexibility when waving action, but can prevent the longitudinal arched district depression of pin when walking.In this application, zone below the longitudinal arched district between among the pin being diminished or remove fully makes the arch area of liftable pin when waving action, and the middle body of footwear will be kept rigid structure and avoid major axis destroyed.

Briefly, for realizing aforementioned and other purposes, an aspect of of the present present invention provides a kind of footwear construction that the rigid shape apparatus for correcting is arranged, the rigid shape apparatus for correcting comprises a device that anatomic shape is arranged with cup and section, it extends to nearest metatarsal forward terminal from distal tip, this device is rigidly fixed to the upper surface of shoe tree/insole as structural detail, this rigid mount comprises the cup of following of a dark conformal, and extend to position after the metatarsal front end area from heel, make and/or machined is made with mould, make pin in footwear, take correct position on the anatomy with the bottom surface that is fit to pin.As described, the present invention's device is similar to the apparatus for correcting of pin traditionally.Yet unlike the apparatus for correcting of pin traditionally, the present invention's device comprises the structural detail of an integral body in footwear, and it more can stablize wearer's pin in footwear, and can not need a sole stage casing that separates, and therefore dual function is arranged.

Preferred embodiment according to the present invention is applied on the high-heeled shoes, this rigid mount comprises the heel seat (with respect to the plane, imagination sole stage casing of shoes) at a little downward inclination angle, and arch support device, it extends and has a primary importance support wearer's nut bone front end forward from heel seat, also comprise a shoe tree (insole) plate in the footwear, its primary importance from arch support is extended forward and downward, and a toe supporting zone extends upward forward with an angle from shoe tree (insole) plate, therefore, wearer's first metatarsal bone by the phalanx support with prevent pin with respect to shoes to front slide, therefore, can prevent finger toe portion extruding in footwear, feasible wearer's body weight with respect to the standard high-heeled shoes will be increased about 16% or more by the weight that heel seat bears.

With reference to Fig. 2, it is for the present invention's preferred embodiment.As the situation of the footwear of Fig. 1, the footwear that show among Fig. 2 have about two inches with high.Yet unlike the conventional footwear of Fig. 1 demonstration, the footwear in Fig. 2, heel seat 20 are (arrow C L direction) rotation along clockwise direction, with respect to basal plane 18 and sole " H " at angle, according to routine formula down:

H=5 °+(α * 1.25 °) α=surpass height of following of 1 " back is with 1/2 " be section wherein.

It is the pin arch area below that end margin extends to the wearer forward before the heel seat 20 that one arch support 22 has part at least.The profile of arch support 22 has a high point 23, and it forms a barrier and prevents the calcaneum of wearer in footwear to front slide, and arch support 22 is bent downwards to sole 24 from height point 23 and combined toe zone 26 in footwear.

Sole 24 is to tilt with an angle " M ", according to following formula with respect to basal planes tilted:

M=18 °+(α * 3.5 °) α=surpass height of following of 1 " back is with 1/2 " be section wherein.

For preventing that putting 23 at height too highly causes the discomfort to the wearer, keeping above-mentioned " M " is critical with respect to the relation with height to the present invention with " H ".Therefore, with increasing the relation that changes M/H, will cause the wearer to impose on the change of the body weight size of heel seat with high α.

The toe zone is to be inclined upwardly forward with an angle " T " in the footwear, with respect to the about 2-3 of basal plane ° ± 1 °.

Downward-sloping heel seat of the present invention, the profile of the arch support 22 of the extension of a heel seat of formation, being inclined upwardly of toe zone combines in the inclination in sole stage casing and the footwear, makes the body weight of the higher percentage of wearer be carried or support by heel seat than the high-heeled shoes of a tradition.High-heeled shoes constructed in accordance respectively and traditional high-heeled shoes of an equal height are relatively, in footwear, carry out pressure measxurement under the spherical bone of wearer's heel seat and pin, show that high-heeled shoes constructed in accordance provide the body weight that increases about 16-18% to be carried on wearer's heel, and therefore the weight of wearer's spherical bone carrying of pin when walking descend, the footwear of the present invention's design, the body weight of wearer's major part is born by heel seat, rather than be transferred to the spherical bone of pin in sole and the footwear, thereby can avoid the toe extruding and guarantee comfortable.

According to Fig. 3, dotted line shows the high-heeled shoes according to the present invention's making, heel seat angle H, and the inclination angle M of first metatarsal bone, and at the inclination angle T of the big pin thumb in toe zone with respect to basal plane 18.α representative is with high, and solid line represent the high-heeled shoes (for example Fig. 1 is shown) of prior art one of corresponding group angle and inclination in Fig. 3, to the present invention similar comparison of following high data is arranged.The footwear of prior art, its heel seat inclination is for upwards square at the angle of about 8 degree X after footwear, and first metatarsal bone is downward and the Y at an angle that turns forward, about 27 degree, big toe is for making progress and the Z at an angle that turns forward about 1  degree.These angles are with respect to basal plane 18, and the footwear of similar relatively size.

The simple and clear explanation of mechanics to pin may promote to understand helpful to the function of footwear of the present invention.Pin can two modes of separating machinery work, so that body support.The main effect of pin as a beam with bending strain mode body support.(power that arch flattens) is that this supported mechanical has effectiveness when relatively hanging down on the arch when external force acts on.This occurs in the body wt center and drops in the paces afterwards of ankle joint.When the body wt center by before the ankle joint, as occur in one normally forward in the paces, the power of appearance begins to cause arch to flatten.Consider this point, pin begins to change over the frame support of spreading out substantially from the supported mechanical state then can be supported via compression strain.Because it is extremely strong that the pin bone has been considered to aspect compressive strength, compression strain is big more, and the arch support degree is good more.For making pin can in supported mechanical, reach this change, the toe support that metatarsal must be bent, this buttressing effect prevents that metatarsal from can become compression from bending and support to advancing slip and feasible.

Heel seat combines with effect, shape and the inclination of arch support advantage of the present invention is provided in the design of footwear of the present invention.By preventing metatarsal to front slide for particular platform surface of pin creation begins a buttressing effect in more effective mode, the result is squeezed to most advanced and sophisticated problem with regard to the toe of eliminating thereafter in footwear.

As increasing angle of bend, the back of the body song of toe in footwear reaches in one of two ways.The shoes front end can upwards be improved causes a kind of " gods and spirits " (genie) formula footwear.Though this will have effect, can not become popular especially form.A more effective mechanism allows metatarsal itself to increase near the angle of sole.This has the effect of the bending that increases toe and need not make a kind of " gods and spirits " formula footwear.Metatarsal can reach by the change of shoes rear structure with respect to the angle increase of basal plane, particularly changes the angle of heel seat 20, and extending under wearer's nut bone by arch support of before having discussed reaches.Because the joint of pin is at each diverse location, calcaneum (heel bone) will be by the gradient compensation of metatarsal near the spherical bone of pin with the angle of basal plane.This angular relationship is inversely proportional to, the parallel more basal plane of calcaneum (as long as the suitable height of following is arranged), and metatarsal is more near a upright height, and therefore the decline angle by providing the heel seat of the low gradient is arranged with the increase metatarsal can meet the requirements of supporting role.

In the present invention, it is relevant with sole and irrespectively downward-sloping with height that heel seat is held, and wearer's nut bone is supported by the arch area of extending forward from heel seat.In the footwear design of prior art, following of footwear is high more, and the heel seat angle is more near the sole angle.This dependency relation causes the platform of a pin towards floor tilt in prior art shoes design skill.The angle of this increase make successively pin to advancing slip and in footwear toe portion be extruded.Its heel seat of the footwear of the present invention's manufacturing is downward-sloping with respect to the sole stage casing, and do not consider how follow height, and provide an arch area under wearer's boat-shaped bone, support this boat-shaped bone, thereby cause a plane to make wearer's body weight of bigger percentage be carried by heel seat.Metatarsal angle (with respect to the sole of shoes) increases with following height with being directly proportional, and for example, with Gao Yuegao, the metatarsal angle is big more with respect to the floor.Surpassing in 2 inches the footwear with high, its advantage is not to increase metatarsal to tilt, but owing to keep heel seat to be aligned to the more approaching basal plane that is parallel to, causes the result of its biomethanics change in metatarsal tilts.

When inclination angle such as above-mentioned, toe zone, emphasize this effect, so that increase the angular flexibility of toe.Because this special design, loading on distribution between pin and the footwear is effectively, thereby the wearer is when standing, because of most of body weight of wearer is born by heel seat, rather than transferred to by the inclined-plane of the shoes of prior art on the spherical bone of pin, and generation problem as previously mentioned.Therefore, adopt design of the present invention, can prevent the toe extruding and guarantee comfortable.

Though above-mentioned explanation is corresponding to No. 7, Unite States Standard women's shoes, it has 2 inches with high, and the present invention is the Unite States Standard women's shoes that special design is suitable for all common scopes, and the scope that is specially adapted to No. 5 to No. 10; The women's shoes that is fit to has various differences to follow high and is particularly suitable for following from 1 to 3 inch of high scope.Different shoes size is arranged and with high, metatarsal tilts difference, if 1 inch with high within about 18-22 degree scope, and 3 inches with high within about 33-36 degree scope.Fig. 2 and Fig. 4-7 and following table 1 are pointed out high-heeled shoes constructed in accordance, and 1  inch (Fig. 5), 2 inches (Fig. 2), 2  inches (Fig. 6), and 3 inches (Fig. 7) are arranged with high 1 inch (Fig. 4).
