It should be noted that, if the direction of the shearing force F ' of foot is counter clockwise direction (also not shown in Fig. 5 a), the part that described waveform tie S302 is connected to described loop tunnel S301 upper surface is not easy to follow described shearing force F ' generation deformation, because the less oblique or lateral shear of making by foot lateral foot inner side of foot moves, simultaneously, if described waveform tie S302 is towards all easily deformation of two kinds of directions, can reduce the restorative of this waveform tie S302, so, adopt in the present embodiment the easy deformation of direction of the more general oblique or lateral shear motion towards foot outside, the direction that oblique or lateral shear towards foot inner side moves is not easy the structural design of deformation.
Thereby described waveform tie S302 can be difficult to deformation in the direction contrary with shearing force, for the stage of stretching of pedaling in shear action provides support structure, can not affect follow-up leg extension.
Compared with prior art, a kind of sport footwear with the shearing damping device of annular flabellum shape hollow out layout described in the utility model, has reached following effect:
1) the utility model can provide the shearing shock-absorbing function of horizontal direction and the gravity bumper and absorbing shock function on vertical direction for human body when doing high-intensity transverse rotation shear action; in comfort cushioning effect on maintaining vertical direction, also play in the horizontal direction good frictional force cushioning effect; greatly reduce the phase mutual friction between foot and footwear binding face, and then protected sporter's the foot injury-free.
2) buffer stage that the utility model can be done in lateral shear action at human body provides larger structural deformation, for the shearing force damping producing in shear action, rotation when the shearing damping device of annular is also conducive to the motion of human body lateral shear simultaneously, thereby lifter motion performance.
3) shock-damping structure of the present utility model can also be difficult to deformation in the direction contrary with shearing force, for the stage of stretching of pedaling in shear action provides support structure, can not affect follow-up leg extension; Shock-damping structure of the present utility model can be used on sport footwear effectively simultaneously.
The foregoing is only embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in claim scope of the present utility model.
