Embodiment five
Below in conjunction with Fig. 5 a and 5b, the embody rule of the sport footwear of described shearing damping device S30 is described in detail:
When foot carries out oblique shear campaign, the shearing force F produced between sole bottom surface and sole surface is (counterclockwise) as shown in Figure 5 a, meanwhile, the reaction force F ' (i.e. frictional force F ') of this shearing force F is produced between sole bottom surface and sole surface, the part that waveform tie S302 in described shearing damping device S30 is connected to loop tunnel S301 upper surface easily follows described shearing force F generation stress and deformation (being counterclockwise stress and deformation in fig 5 a), described shearing force F is cushioned, thus dissolve or weaken shearing force F described in this shearing force F(and weaken, its reaction force F ' also weakens thereupon), protective effect is produced to foot.Meanwhile, described reaction force F ' show as in actual applications described shearing damping device human body do lateral shear motion after be in pedal stretch the stage time, resiliency supported is provided, follow-up leg extension can not be affected.After shear action terminates (after namely shearing force F disappears); the deformation that described waveform tie S302 is connected to the part of described loop tunnel S301 upper surface returns to original state as shown in Figure 5 a; thus shearing shock-absorbing function can be provided for human body when the lateral shear action doing high strength; play good cushioning effect; significantly reduce the phase mutual friction between foot with footwear binding face, and then the foot protecting sporter is injury-free.In whole stress and deformation process, the part that described waveform tie S302 is connected to described loop tunnel S301 lower surface is mainly played a supporting role, and follows the first half generation deformation of this waveform tie S302.
It should be noted that, if the direction of the shearing force F ' of foot is counterclockwise (in Fig. 5 a and not shown), 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 ' and deformation occurs, because the less oblique or lateral shear motion made inside by foot lateral foot of foot, simultaneously, if described waveform tie S302 is all easily deformation towards two kinds of directions, then can reduce the restorative of this waveform tie S302, so, adopt the more general easy deformation in direction towards the oblique or lateral shear motion outside foot in the present embodiment, direction towards the oblique or lateral shear motion inside foot is not easy the structural design of deformation.
Thus 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, follow-up leg extension can not be affected.
Compared with prior art, a kind of sport footwear with the shearing damping device of annular flabellum shape hollow out layout described in the application, reaches following effect:
1) the application can provide the gravity bumper and absorbing shock function on the shearing shock-absorbing function of horizontal direction and vertical direction when doing the transverse rotation shear action of high strength for human body; also good frictional force cushioning effect is played in the horizontal direction while maintaining the comfort cushioning effect on vertical direction; significantly reduce the phase mutual friction between foot with footwear binding face, and then the foot protecting sporter is injury-free.
2) the application can provide larger structural deformation at the human body buffer stage done in lateral shear action, for the shearing force damping produced in shear action, the shearing damping device of annular is also conducive to rotation when human body lateral shear moves simultaneously, thus lifter motion performance.
3) shock-damping structure of the application 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; The shock-damping structure of the application can be used on sport footwear effectively simultaneously.
