Detailed description of the invention
Sport shoes 1 partly illustrates in Fig. 1 is to 5.These footwear 1 are particularly suited for playing tennis.
As shown in Figures 2 and 3, footwear 1 include the outer bottom 3 suitable in earth surface, are arranged to the inner bottom (illustrating in figs. 6 and 7) being arranged in below athletic foot P and the end 5 being vertically inserted between outer bottom 3 and inner bottom.Footwear 1 also include not shown vamp, flap and fastening component.
Footwear 1 define the longitudinal axis X-X extended between the leading section 10 of footwear 1 and rearward end 12 on the whole '.In the remainder of description, adjective " front " and " afterwards " reference axis X-X ' and leading section 10 and rearward end 12 and used.
Similarly, footwear 1 define the transverse direction Y-Y ' being perpendicular to axis X-X ', and transverse direction Y-Y ' extends between the inner side I and outside E of foot P, the inner side I of foot P is arranged in the left side in the right side of Fig. 1 and Fig. 4, and the outside E of foot P is arranged in the right side in the left side of Fig. 1 and Fig. 4.The inner side of foot P is directed towards the vertical central axial line of human body.In the remainder of description, adjective " interior " and " outward " are used with reference to transverse direction Y-Y '.
Foot P includes five toes, and these five toes include the big toe 21 being positioned at the inner side of foot P, and be respectively labeled as from the inner side of foot towards outside 22,23,24 and 25 the second toe, the 3rd toe, the 4th toe and the 5th toe.
As it is shown in figure 1, outer bottom 3 longitudinally axis X-X ' is divided into three transverse areas.
The first area 3A being referred to as forefoot area extends between the region of leading section 10 and the base portion of the toe corresponding to athletic foot P of footwear 1.Therefore, forefoot area 3A is on the whole corresponding to the region being used for being at least partially situated at below athletic toe of outer bottom 3.
Distance between leading section 10 and rearward end 12 is defined as the total length of outer bottom 3.
The distance that forefoot area 3A extended from leading section 10 is between 10% and 30% of the total length of outer bottom 3A.
It is referred to as the second area 3B in intermediate lateral region to be arranged to region between the leading section P1 in the base portion at toe of foot P and the bow portion of foot at least in part and extend below, the bow portion of foot and the arch area of foot P, is also referred to as " arch of foot ".This region is the part of maximum meats of foot P, when in motion and when being especially at tennis, pressure will be greatly born in this region.When player support its move before the ball is hit time, most of body weight is by this part being supported on foot P.
Zone line 3B extended distance between 15% and 25% of the total length of outer bottom 3 from forefoot area 3A.
The 3rd region 3C, the 3rd region 3C that outer bottom 3 includes being referred to as rear region is configured to be positioned at the lower section in the leading section P1 in the bow portion from foot of the foot P region extended back.Rear region 3C is provided in arch of foot and extends below.
Rear region 3C extended distance between 20% and 40% of the total length of outer bottom 3 from zone line 3B.
Alternatively, outer bottom 3 also includes the 4th transverse area 3T that is arranged to be positioned at below heel.Region 3T extands rearward to rearward end 12 from rear region 3C.This region 3T from the rear region 3C distance extended between 20% and 40% of the total length of outer bottom 3.
Region 3A is separated with region 3B by the first horizontal curve 30, and region 3B is separated with region 3C by the second horizontal curve 32.Horizontal curve 30 is configured to be found in the lower section of the base portion of toe on the whole.Horizontal curve 32 is configured to be found in the lower section of the leading section P1 in the bow portion of foot P on the whole.Curve 30 and 32 constitutes the band of outer bottom 3, the pliability of this band pliability more than region 3A, 3B and 3C.Pliability refers to the deformability of material under the effect of bending force.In other words, the deformability of the outer bottom 3 in curve 30 and 32 is more than the deformability of the outer bottom 3 in region 3A, 3B and 3C.Therefore, curve 30 and 32 enables region 3A, 3B and 3C relative to each other hinged (articulate).
Therefore, when especially playing tennis when carrying out moving, when the meat region that the major part of body wt is placed between the leading section P1 in the base portion of toe and the bow portion of foot to extend, especially during wait attitude before netman is in by the impact of opponent, outer bottom 3 is particularly suited for being supported.Intermediate lateral region 3B bears pressure especially in such an embodiment.
When player rushes forward, forefoot area 3A makes to support on the ground player, and therefore bigger thrust is delivered on ground by his toe.Pliability accordingly, with respect to intermediate lateral region 3B, forefoot area 3A makes it possible to transmit energy to better ground, and thus adds the proal efficiency of player.
As illustrated in fig. 1 and 2, outer bottom 3 transversely axis Y-Y ' is also divided into three longitudinal regions.
The the first longitudinal region 3D being referred to as inner region extends from the inward flange 34 of outer bottom 3, and is configured to be at least partially situated at the lower section of big toe 21.Inner region 3D extends in forefoot area 3A, in zone line 3B and in rear region 3C.
Distance between inward flange 34 and outward flange 36 is defined as the overall width of outer bottom 3.
The distance that inner region 3D extended from inward flange 34 is between 20% and 40% of the overall width of outer bottom 3.
The the second longitudinal region 3E being referred to as central authorities' longitudinal region is configured to be at least partially situated at the lower section of the second toe 22 and the 3rd toe 23.Region 3E partly extends in forefoot area 3A and zone line 3B, and is partly extended to rear region 3C.
Middle section 3E from the inner region 3D distance extended between 20% and 40% of the overall width of outer bottom 3.
The 3rd region 3F being referred to as exterior domain extends from the outward flange 36 of outer bottom 3, and is configured to be at least partially situated at the lower section of the 4th toe 24 and the 5th toe 25.Region 3F extends in part in forefoot area 3A and zone line 3B, and is partly extended to rear region 3C.
The distance that exterior domain 3F extended from outward flange 36 is between 20% and 40% of the overall width of outer bottom 3.
Longitudinal region 3D is separated with longitudinal region 3E by Vertical Curve 38, Vertical Curve 38 is configured to be approximately between big toe 21 and the second toe 22 and passes, and longitudinal region 3E is separated with longitudinal region 3F by Vertical Curve 40, Vertical Curve 40 is configured to be approximately between the 3rd toe 23 and the 4th toe 24 and passes.The pliability of curve 38 and 40 pliability more than longitudinal region 3D, 3E and 3F.With with the same way for transverse area, this pliability makes the longitudinal region can be relative to each other hinged, and can better transfer force to ground when moving.
When playing tennis, lateral movement is to need speed and explosive force and extremely dominant aspect.For this, the transmission of the power between foot and the ground of netman is able to ensure that the efficiency and speed that direction changes, and the change in direction causes the speed in different directions to slow down, and stops and restarting.When player's slow-down after running, exterior domain 3F bears pressure, and this respect is also important.
As it is shown in figure 1, due to the different form of foot, region 3A, 3B, 3C, 3D, 3T, 3E and 3F location may not strictly correspond to the position of different piece of foot.Some toes are likely to especially span two longitudinal regions, and Vertical Curve 38 and 40 possibility will not strictly through big toe 21 and the second toe 22 and between the 3rd toe 23 and the 4th toe 24.
The middle end 5, includes the liner being stacked on forefoot area 3A and intermediate lateral region 3B.These liners include the inner liner 50 that entirety is stacked on inner region 3D.Inner liner 50 is allowed for better dynamic pressure distribution and for the better dynamic return storing energy during the pressure to the inner side of foot, such as the, when spring after fulminant startup or service the is landed return of stored energy, includes the sizable power for shifted laterally transmitted by big toe 21 to the inner side pressure applied of foot.
The middle end 5, also includes the center liner 52 that entirety is stacked on central authorities longitudinal region 3E.This liner bears pressure in the period of the weight transition phase of health or the period on grappling ground before the ball is hit, and is needs in support stable during this period.
The middle end 5, also includes the 3rd outer liner 54 that entirety is stacked on exterior domain 3F.During giving the 4th toe 24 and the 5th toe 25 thrust such as, during the deceleration after lateral stroke or when mobile or during the change of direction, the pressure being applied to the outside of foot can be carried out being distributed and start to restart by pad 54.
Center liner 52 is formed by expanding material, and center liner 50 and 54 is bonded in this expanding material, and expanding material extends to the rear portion at the middle end 5.Liner 50 and 54 is the liner being attached in the chamber of center liner 52.
Alternately, center liner 52 can be have same kind of attachment liner with liner 50 and 52, and forms the element of the remainder independent of the middle end 5.Center liner 52 can also be made up of stiffener, for instance the band of plastics, carbon or other material, and this stiffener is located between liner 50 and 54 in the outer housing of extension.
In order to allow the more dynamic (dynamical) motion of player, inner liner 50 and outer liner 54 are made up of the material with high-energy resettability, and the energy resettability of this material has exceeded the energy resettability of the material making center liner 52.More specifically, the material of liner 50 and 54 has elasticity, being namely rapidly returned to the ability close to its original shape after deformation, this ability of the material of liner 50 and 54 has exceeded this ability of the material of liner 52.Therefore, during using big toe 21 to support or use the lateral movement that the 4th toe 24 and the 5th toe 25 support, or when such as utilizing the 4th toe and the 5th toe to carry out stopping suddenly, foot can be buffered, subsequent to improve the execution speed of direction change and therefore improve the performance of all footworks of player, energy can be returned.Liner 50,52 and 54 makes it possible to improve the effectiveness of the power transmission between player and ground during lateral movement with the overlapping of the longitudinal component divided by region 3D, 3E and 3F of outer bottom 3.
Exemplarily, inner liner 50 and outer liner 54 can be made up of vibration-absorptive material and elastomeric material, for instance synthetic foam or rubber.Center liner 52 can be made up of rigidity or semirigid synthetic foam.
Alternatively, the middle end 5, also includes the rear liner 56 being stacked on the 3T of region, and it is visible to provide the damping on heel that rear liner 56 is provided under heel.In this example, rear liner 56 is comprised in center liner 52.
Curve 30,32,38 and 40 is formed by the groove 42 extending side by side on the outer surface S3 of outer bottom 3.Rib 44 extends between each groove 42.At groove 42 place, the thickness of outer bottom 3 reduces therefrom, which increases pliability.
In unshowned alternative scheme, curve can be formed by single groove 42.
Preferably, groove 42 is considered relative to outer surface S3 and has the degree of depth, and this degree of depth is between 0.5mm and 5mm, and is applied on average thickness sole 3 between 3mm and 5mm.Therefore, groove has the degree of depth of the 10% to 100% of the average thickness being rendered as sole 3.
A unshowned alternative scheme according to the present invention, groove 42 can pass the whole width of outer bottom 3 so that the middle end 5 is visible in the upward view of footwear 1.
Preferably, curve 30,32,38 and 40 has the width between 1mm to 10mm.
As it is shown in figure 1, curve 30,32,38 and 40 has the rectilinear form of bending.Generally, curve 30,32,38 and 40 has at least part of rectilinear form.In the alternative scheme shown in Fig. 5, curve 30,32,38 and 40 also can have the shape of bending at least partly.
Horizontal curve 30 and 32 has concave shape, its concave side towards rear with the natural curve of the leading section P1 in the bow portion of the natural curve and foot of following the base portion of toe.
Vertical Curve 38 and 40 has concave shape, its concave side towards the inner side of foot to follow the inward flange of foot and outer peripheral natural curve.
Curve 30,32,38 and 40 is to intersect and form nine sub regions.
Curve 30 and 32 extends to the outward flange 36 of outer bottom 3 and terminated extending before inward flange 34.In unshowned alternative scheme, curve 30 and 32 can make inward flange 34 extend.
Curve 38 and 40 extends near leading section 10 between the middle body 46 of outer bottom 3, and the middle body 46 of outer bottom 3 is provided as being raised relative to ground.In the example in the figures, curve 38 extends to leading section 10, and curve 40 terminated extending before leading section 10.In unshowned alternative scheme, curve 40 may extend into end 10.
The position of longitudinal region 3A, 3B and 3C and transverse area 3D, 3E and 3F, and the position of curve 30,32,38 and 40 can be different, this specific region depending on preferably giving outer bottom 3 but not the importance in other regions.
Such as, footwork rapidly and has fulminant netman and more outwards will support towards front pressurized zone 3A and 3B, or with region 3D and 3F laterally to outer support.In this case, this player will apply pressure to all of region of outer bottom 3, therefore, compares the footwear of player for having less explosive footwork, and region 3A, 3B, 3D and 3F will have bigger area.
This have more smooth, speed is slower and the player of the Second Type of more ground footwork will support or period of batting forward advance more pressure to less degree 3A on the 3B of region, and in the change of direction and retardance, region 3E and 3D will be pressed by the player of this Second Type more.Therefore, region 3E and 3D will have bigger surface area on the footwear with more smooth and more landing operation and less fulminant footwork be designed to player.
Fig. 6 and 7 have illustrated an alternative embodiment of the present invention.It is also referred to as socks lining and is advantageously able to the inner bottom 7 from footwear remove and contacts with foot.Inner bottom 7 includes the bottom surface 71 contacted with the middle end 5.
In the way of identical with outer bottom 3, described bottom surface 71 is divided into the multiple transverse areas and longitudinal region that are separated by curve, these transverse areas and longitudinal region and aligns with region and the curve of outer bottom 3.Bottom surface 71 includes the forefoot area 71A being stacked on forefoot area 3A, the intermediate lateral region 71B being stacked on the 3B of intermediate lateral region and the rear region 71C being stacked on rear region 3C.In the way of identical with curve 30 and 32, region 71A, 71B and 71C are separated from one another by horizontal curve 711 and 713, and this horizontal curve 711 and 713 is stacked on horizontal curve 30 and 32 and has the pliability that the pliability than region 71A, 71B and 71C is bigger.
Bottom surface 71 includes the inner region 71D being stacked on inner region 3D, the longitudinally central region 71E being stacked on central authorities longitudinal region 3E and the exterior domain 71F being stacked on exterior domain 3F.In the way of identical with curve 38 and 40, region 71D, 71E and 71F are separated from one another by horizontal curve 715 and 717, and horizontal curve 715 and 717 is stacked on horizontal curve 38 and 40 and has the pliability that the pliability than region 71D, 71E and 71F is bigger.
The structure of this inner bottom 7 overlapped with the structure of outer bottom 3 can improve the pliability of footwear 1 entirety, and makes to support ground effectively by the different piece of foot.
Alternately, bottom surface 71 is formed by the ground floor of inner bottom 7, and inner bottom 7 includes the second layer 73, i.e. upper strata, and this second layer is stacked on bottom 71 and contacts with foot.According to unshowned preferred aspect, top layer 73 can include the liner being made up of the material of different-energy transport capability, this liner utilize the liner 50 with the middle end 5,52 and 54 identical geometry and identical principle as one man position with region 71A to 71F.
