The specific embodiment
With reference to Fig. 1, show a kind of sport footwear or playshoes 100, the footwear outer bottom 200 that it comprises traditional upper shoe part 102 and is fixed to upper shoe part 102.Footwear outer bottom 200 is by being fixed to upper shoe part 102 such as the conventional method of using the footwear binding agent.
As shown in Figure 3, footwear outer bottom 200 comprises upper sole 202, is arranged at the sole layer 204 under the upper sole 202, and is arranged at the resilient midsole 206 between upper sole 202 and the sole layer 204.Preferably, upper sole 202, sole layer 204 and midsole 206 are made by the elastic caoutchouc compound.More preferably, midsole 206 is one-body molded with upper sole 202 and sole layer 204.
Upper sole 202 has loe zone 208 at the end place near upper sole 202, and has heel area 210 at the other end place near upper sole 202.During use, when pin is put into footwear 100, between upper shoe part 102 and footwear outer bottom 200, toe will be resident near loe zone 208, and heel is resident near heel area 210 simultaneously.
Preferably, upper sole 202 is one-body molded near loe zone 208 places and sole layer 204, but only is connected to sole layer 204 by midsole 206 and flexible U-shaped hinge 226 at heel area 210 places, and wherein, resilient U-shaped hinge 226 is outstanding backward from footwear outer bottom 200.Clearly, when footwear outer bottom 200 was subjected to loading, this set allowed upper sole 202 to move both vertically with respect to sole layer 204 in heel area 210, thereby the cushioning effect of vertical direction is provided for pin.
Preferably, sole layer 204 comprises several substantially parallel elasticity ribs 212, is used to increase the frictional force of footwear 100.Each rib 212 all extends away from upper sole 202 downwards, crosses the width of sole layer 204.
As shown in the figure, each unsteady hinge 214 U-shaped spring 220 of all comprising upper leaf spring 216, lower leaf spring 218 and being used for leaf spring 216,218 is coupled together.Upper leaf spring 216 has a root 216a and the head 216b relative with root 216a.Each upper leaf spring 216 is one-body molded at its root 216a and upper sole 202.Similarly, lower leaf spring 218 has a root 218a and the head 218b relative with root 218a.Each bottom leaf spring 218 is one-body molded at its root 218a and sole layer 204.
As shown in the figure, all lobed profile of each leaf spring 216,218, wherein, each leaf spring 216,218 is near root 216a, and the radius of curvature of 218a is greater than near head 216b, the radius of curvature of 218b.Yet the profile of each upper leaf spring 216 is opposite with the profile of each lower leaf spring 218.
Leaf spring 216,218 extends laterally across footwear outer bottom 200, preferably passes the whole width of footwear outer bottom 200.Preferably, the thickness of each leaf spring 216,218 is at root 216a, and 218a and head 216b are constant substantially between the 218b, and also constant substantially when passing the whole width of footwear outer bottom 200.
In addition, preferably, midsole 206 comprises insertion passage 222, and it makes and float hinge 214 and insert the width that passage 222 does not interruptedly extend through footwear outer bottom 200 continuously between every pair of adjacent unsteady hinge 214.Alternatively, one or more insertion passages 222 can be filled with elastic foam material, to give the elasticity of footwear outer bottom 200 expections.
Each U-shaped spring 220 all has a pair of whole leg 220a that connects, 220b.A leg 220a of each U-shaped spring 220 is arranged on another leg 220b top of identical U-shaped spring 220.Furthermore, each leg 220a, the cross section of 220b are basic planes, and horizontal expansion runs through footwear outer bottom 200.As shown in the figure, each U-shaped spring 220 includes a passage 224 that is made of upper leg 220a and lower leg 220b, its horizontal expansion runs through the width of footwear outer bottom 200, and is not in load following time with upper leg 220a and lower leg 220b separately at footwear outer bottom 200.
The top leaf spring 216 of each unsteady hinge 214 is all integrally formed at head 216b place with the upper leg 220a of the U-shaped spring 220 that is associated.Similarly, the bottom leaf spring 218 of each unsteady hinge 214 is all integrally formed at head 218b place with the lower leg 220b of the U-shaped spring 220 that is associated.
Preferably, leaf spring 216,218 has essentially identical length and curvature, and U-shaped spring 220 basic spacings be arranged between upper sole 202 and the sole layer 204.Further preferably, the hinge 214 that floats is positioned such that U-shaped spring 220 is towards loe zone 208 location; And the root 216a of leaf spring 216,218,218a is towards heel area 210 location.
From the above, the characteristic of leaf spring 216,218 rubber-likes, and both have opposite protruding profile.Therefore, (for example, top bar owing to wear the people of footwear 100) when the normal load on the footwear outer bottom 200 increases, the leaf spring 216,218 of pressurized will be by stretching the vertical compression of resisting footwear outer bottom 200 gradually.
Because leaf spring 216,218 has variable radius of curvature (from the above), when the load that is subjected to vertical direction (for example, owing to wear the people's of footwear 100 body weight) time, the head 216a of leaf spring 216,218,218a will be than root 216b, the shape when 218b is easier to depart from it and is not subjected to load.Because the normal load on the footwear outer bottom 200 increases, the head 216a of leaf spring 216,218,218a will be adjacent to each other (as Fig. 2 and shown in Figure 4), thereby stop leaf spring 216,218 at head 216a, the continuation at 218a place distortion.Yet the root 216b of leaf spring 216,218,218b be the shape when beginning to depart from it and be not subjected to load subsequently.As a result, 216,218 pairs of foots of leaf spring provide vertical buffering progressively.
Preferably, each U-shaped spring 220 all has elasticity, and U-shaped spring 220 is stronger than the elasticity of leaf spring 216,218.Therefore, when applying normal load at first, U-shaped spring 220 will at first be resisted the compression of footwear outer bottom 200, follow by leaf spring 216,218 distortion.As a result, because this setting subsequently, can further provide progressively cushioning effect to foot.
Equally preferably, float hinge 214 near the height at heel area 210 places height, so that the heel place is provided the cushioning effect of enhancing greater than loe zone 208.Yet footwear outer bottom 200 can have alternative cross-sectional shape, to strengthen the distribution of load.For example, can be bigger at footwear outer bottom 200 near zones corresponding than height such as the unsteady hinge 214 at pin nurse toe and heel place with foot peak load point, to strengthen support to these positions of pin.
This paper has expected to the various distortion of previous embodiment.For example, midsole 206 is typically made standard size, and promptly all the thickness and the size of leaf spring 216,218 are basic identical.As a result, by increasing or reduce the thickness of whole leaf springs 216,218 and/or the vertical buffering that size just can obtain desired amount.Yet, alternatively, can increase or reduce the thickness and/or the size of individual leaf springs 216,218, so that provide selectable vertical buffering in certain location along footwear outer bottom 200.And, can regulate vertical buffering capacity by the material of suitably selecting to make leaf spring 216,218.
Equally, also can select the quantity of the unsteady hinge 214 on the midsole 206 (density) of unit length, so that the bufferings of different amounts are provided for foot.This variable density can be by increasing or reduce the size of inserting passage 222 and/or realizing by length or the angle that increases or reduce leaf spring 216,218.And it is consistent that the density (as defined above) of the hinge 214 that floats needs not be, but can be along the length variations of footwear 200.For example, near the density of the unsteady hinge 214 in the zone the footwear 200 corresponding with pin nurse toe and heel can be bigger, and near the density of the unsteady hinge 214 in the zone the footwear corresponding with arch 200 can be less.
In addition, from the above, typically, the thickness of each leaf spring 216,218 is at root 216a, and 218a and head 216b are substantially invariable between the 218b, and the whole width that runs through footwear outer bottom 200 all is substantially invariable.Yet alternatively, the thickness of each leaf spring 216,218 can be at root 216a, and 218a and head 216b change between the 218b, so that different progressive vertical buffering profiles to be provided.
Above description explain clear the preferred embodiments of the present invention, attached claim so far defines patent right of the present invention scope required for protection.Though this paper does not offer some clarification on, those those of ordinary skill can carry out some to described embodiment to be revised, and does not depart from this as scope of invention that appended claims limited.
