Enlarged drawing shown in Fig. 7 A and Fig. 7 B has illustrated that flexible heel inserted block 28 is the flexibilities how vertical direction is provided for footwear 10.In the situation of Fig. 7 A, suppose that footwear are shelved on the floor, do not exert pressure.In this case, cushion thin section width and be its maximum.At this moment, the width RD of the thin section of the buffering of front side
H1Preferably and the width RD of the thin section of buffering of rear side
H2Equate, but this is not essential.Similarly, cushion thin section and also can be identical size along inboard with the width in the outside.
In a preferred embodiment, under state non-loaded or not pressurized, along the front side, the zone such as rear side, inboard and outside, the width that cushions thin section is uniform substantially.In one example, under state non-loaded or not pressurized, cushion thin section width and be about 5.0mm.In another example, under the state of pressurized, do not cushion thin section width and can be between the 3.0mm to 7.0mm.In an example again, under the state of pressurized not, cushion thin section width and can be at least 1.5mm.In another example, under the state of pressurized not, cushion thin section width and can be and be not more than 10.0mm.
In another embodiment, cushion thin section and need not Perfect Ring around heel.For example, front side portion can be concordant with heel or be connected, and other three sides have the thin section of buffering.When wearer's body weight evenly distributes along footwear, can provide like this buffering and increase stability to the heel bump.This is shown in Fig. 7 C, and heel spare 14 comprises the front side portion 50 that does not cushion thin section.Front side portion 50 can be the part of flexible heel inserted block 28 or heel post 26, or the part of these two elements.Fig. 7 D shows the change example that comprises a plurality of front side portions 52, and it also possesses above-mentioned advantage.
Certain width can change according to impact-attenuating amount and/or required style.Compare with the thin section of narrower buffering width, cushion thin section wider width and will allow flexibility on the larger vertical direction.In one case, cushioning thin section width can change according to the type/style of high-heeled shoes.For example, and according to aesthstic designing, still keeping the flexibility of threshold level and the footwear of impact-attenuating to compare when heel clash into simultaneously, the footwear as the sale of the most comfortable high-heeled shoes can have the thin section of wider buffering.
In case after applying force to heel spare 14, as footwear worn and will occur during user walks, heel will contact with ground.Under this power effect, flexible heel inserted block 28 is with bending or Partial shrinkage.The width that cushions thin section provides flexibility.When applying power, cushion thin section width owing to flexible heel inserted block 16 crooked reducing.Therefore, at least part of ground reaction force is absorbed, and provides to a certain degree buffering to the wearer.This can find out from the example of Fig. 7 B, the width (RD of the thin section of the buffering of front side
H3) cushion the thin width (RD of section less than the front side shown in Fig. 7 A
H1).Similarly, the rear side among Fig. 7 B cushions the thin width (RD of section
H4) cushion the thin width (RD of section less than the rear side shown in Fig. 7 A
H2).Should be understood that when masterpiece is used in heel spare, the thin section of the buffering in inboard and outside width also will be less when not applying power.
In one example, when not applying power, the rear side among Fig. 7 A cushions the thin width (RD of section
H2) maximum is about 5mm, and when applying power, the width (RD of the thin section of the buffering shown in Fig. 7 B
H4) can reduce about 1mm-2mm(or 20-40%) to 4mm-5mm(or 80-100%) between.The test proof is about 1mm in 50 ft lbf lower compression amounts, is about 3mm 150 pounds of pressure lower compression amounts, and substantially is fully compressed under 200 pounds of pressure.
Cushioning thin section decrement will change according to wearer's body weight and the AD HOC of gait thereof, flexible heel inserted block 28 used materials.For example, for the given embodiment of the invention, the weight that is applied to footwear is larger, and the compression zone that causes can be larger, and the compression zone that less weight causes can be less.Similarly, make 28 pairs of ground of flexible heel inserted block produce the gait of heavier or very fast bump, can cause compression in a big way, and make 28 pairs of ground of flexible heel inserted block produce gait gentle or that clash into more slowly, can lead compression more among a small circle.The hardness on walking ground itself also can affect the compression of the thin section of buffering width.
In addition, according to the difference of shock point, the power that is applied to flexible heel inserted block 28 bottoms 30 may and distribute unevenly.Fig. 8 has illustrated as the wearer and has worn in the shoes example action in when walking that the rear sides 30a of flexible heel inserted block 28 begins tentatively to contact with ground.In one example, the radius R that has of rear sides 30a
PBe about 10mm.In other examples, radius R
PCan be between 5mm and the 15mm or be at least 3mm.Become in the example radius R at some
PCan select according to aesthstic.In one case, maximum radius R
PCan be the scope of 5mm to 40mm.
Radius R
PAdvantage can find when heel clashes into that the conventional high heel that has the straight flange geometric shape with the heel rear sides is compared radius R
PCan allow milder heel bump.Radius R
PRotation action is provided, and has increased the contact area on bottom 30 with the ground of flexible heel inserted block 28, helped the dispersion of contact and make these power upwards not transmit and enter in wearer's body by heel.Since the increase of ground contact, radius R
PAlso increase stability and adhered to frictional force.In one case, the inboard of rear sides 30a and Outboard Sections also can be fillet, have radius R
P, but be not essential.
As also shown in Figure 8, the region of the front side 30b of flexible heel inserted block 28 bottoms 30 also can be fillet, has radius R
aIn one example, radius R
aBe about 3mm.In other examples, radius R
aCan or be not more than 7mm between 1mm to 5mm.As above-mentioned, the region of the front side need not to have any radius R
aAlthough in side view Fig. 8, do not illustrate, among rear lateral areas 30a, region of the front side 30b and the mesozone 30c any or all can comprise tread contour, be used for to strengthen and the contacting of ground.
As noted above, as can be seen from Figure 8, rear lateral areas 30a contacted with ground before the 30b of region of the front side usually.Therefore initial assault and advocate to be applied to rear lateral areas 30a.Therefore, in one case, rear side cushions the thin width RD of section
H4The comparable front side of compression cushion the thin width RD of section
H3Compression larger.
Fig. 9 A and Fig. 9 B have illustrated when the people walks, and cushion the exemplary compression of thin section width.For example, shown in Fig. 9 A, rear lateral areas 30a(is referring to Fig. 8) first kiss the earth, thus cause the thin section of the buffering width in this zone to compress.Then, shown in Fig. 9 B, when the half sole part of article of footwear contacted with ground, region of the front side 30b(was referring to Fig. 8) also contact with ground, cause equally the front side to cushion the compression of thin section.Because gait, body weight and other factors, the compression around the heel spare 14 can be uniformly or can be inhomogeneous.
According to a further aspect of the invention, cushioning the thin RD of section can be set to as much as possible near ground.Compare with conventional high-heeled shoe, the thin RD of section of buffering that arranges by this way, minimum on the impact of the aesthstic aspect of footwear.In addition, when walking, the initial application of force is introduced from the heel end usually.This power dwindles moment arm length in the decay of contact point place.The application of force will increase moment arm to the mechanism that is higher than heel, and amplify the power that is applied to the heel element.The leverage that increases will be introduced more high-torque at heel, cause the heel of underfooting to become unstable.The increase of moment arm will act on being connected of heel spare and sole, and be that heel spare need be fixed on the reason of sole tightly, and require heel spare for unusual rigidity, make such as wooden or plastics.
In one example, cushion the thin RD of section
H1(Fig. 7 A) can be arranged on apart from the bottom surface of region of the front side 30b kiss the earth and be about 4mm to 6mm.In other examples, cushion the thin RD of section
H1Can be arranged on apart from the bottom surface of region of the front side 30b kiss the earth at least 2mm or be no more than 10mm.By contrast, cushion the thin RD of section
H2Can be arranged on apart from the about 10mm to 20mm in bottom surface of rear lateral areas 30a kiss the earth.In other examples, cushion the thin RD of section
H2Can be arranged on apart from the bottom surface of region of the front side 30b kiss the earth at least 7mm or be no more than 30mm.Shown in Fig. 7 A, with respect to the surface of kiss the earth, cushion thin section the position can from region of the front side 30b backward lateral areas 30a raise gradually.
Figure 10 A to Figure 10 E has illustrated the suspend different views of exemplary embodiment of heel of according to the present invention each side.Figure 11 A to Figure 11 E has illustrated the suspend different views of Alternative exemplary embodiment of heel of according to the present invention each side.Dotted line among Figure 10 A to Figure 10 E and Figure 11 A to Figure 11 E has been indicated the top of the heel that suspends, and it can attach on the sole.
