Athletic shoe sole
Technical field
The present invention relates to sport footwear, be specifically related to athletic shoe sole.
Background technology
The bumper and absorbing shock performance of sport footwear is one of main performance index of weighing sport footwear, and the bumper and absorbing shock performance that improves sport footwear is the emphasis research and development content of each sport footwear enterprise.
At present, most sport footwears all is to adopt the stock of high resilience foam as the sole bumper and absorbing shock, though high resilience foam is a kind of very effective vibration-absorptive material, in absorbing vibration, many startup energy also can be absorbed and lose.In most of sports, the sportsman needs the take-off of fast and flexible ground or advances, therefore, when utilizing the high resiliency macromolecular material as the bumper and absorbing shock material, also need carry out structural design according to sports characteristics and sport biomechanics characteristics, when making it have good bumper and absorbing shock performance, also possesses stronger quick startability.
Summary of the invention
Technical problem to be solved by this invention is to solve sport footwear improving buffering and damping effect simultaneously, starts relatively poor problem fast.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention provides a kind of athletic shoe sole, be provided with damping device in the heel of described athletic shoe sole, described damping device comprises, the arc lower plate be connected, the connector of arc lower plate, on described, the material of arc lower plate is TPU, the material of described connector is the PU resin, last arc is presented convex, the arc lower plate is convex down, on, before the arc lower plate, back two ends link respectively and are one, the heel of described sole is provided with and connects a heel left side, the through hole of right flank, the profile of this through hole and described sole damping device is suitable, and damping device is inlaid in the described through hole.
In above-mentioned athletic shoe sole, the profile of described connector is cylindrical shape.
In above-mentioned athletic shoe sole, the profile of described connector is oval bar shape, and long axis direction is consistent with the front and rear direction of athletic shoe sole.
In above-mentioned athletic shoe sole, the profile of described connector is oval bar shape, and long axis direction is consistent with the left and right direction of athletic shoe sole.
In above-mentioned athletic shoe sole, it is up-small and down-big round table-like that the profile of described connector is.
In above-mentioned athletic shoe sole, the middle part of described connector has necking part, and the dual-side of this necking part is the arc of indent on longitudinal profile.
In above-mentioned athletic shoe sole, the bottom surface of described arc lower plate is provided with sheet TPU shock-absorbing elastomer.
The present invention, in the heel of athletic shoe sole, be provided with damping device, this damping device has been used for reference " worker " ellbeam structure of widespread usage on the architecture, form multistage bradyseism system by upper and lower arc and connector, make athletic shoe sole have good bradyseism, have higher quick startability simultaneously again.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is made detailed explanation.
As shown in Figure 1 and Figure 2, athletic shoe sole provided by the invention, its heel 100 is provided with the through hole that connects the heel left and right side, is embedded with damping device 110 in this through hole.The structure of damping device 110 as shown in Figure 3, comprise upper and lower arc 1,2 and the connector 3 that is connected upper and lower arc, the material of described upper and lower arc 1,2 is TPU (TPUE rubber), the material of described connector 3 is PU (Polyurethane, polyurethanes is called for short polyurethane), train wheel bridge 1 is presented convex, lower plate 2 is convex down, and it is one (front and rear direction of alleged forward and backward and sole is consistent among the present invention) that the forward and backward two ends 11,21 of upper and lower arc 1,2 link respectively.In order to realize damping effect better, the bottom surface of arc lower plate 2 is provided with the sheet shock-absorbing elastomer 4 that the TPU material is made.The through hole of perforation heel left and right side and the profile of damping device 110 are suitable.
In such scheme, connector 3 can have various embodiments, respectively referring to Fig. 4-Fig. 9.
As shown in Figure 4, the profile of connector 3 is cylindrical shape.
As shown in Figure 5, the profile of connector 3 is oval column.
As shown in Figure 6, the profile of connector 3 is up-small and down-big round table-like.
As shown in Figure 7, the profile of connector 3 is cylindrical shape, and cylindrical middle part has necking part 31, and the dual-side 32 of this necking part 31 is the arc of indent on longitudinal profile.
As shown in Figure 8, the profile of connector 3 is oval bar shape, and long axis direction is consistent with the front and rear direction of athletic shoe sole, this version is because the length of connector 3 on front and rear direction is bigger, therefore, bradyseism effect to whole heel is better, is applicable to long-distance travel.In order to improve damping effect better, the middle part of oval cylinder has necking part, and the dual-side of this necking part is the arc of indent on longitudinal profile.
In addition, the long axis direction of oval cylinder 3 also can be consistent with the left and right direction of athletic shoe sole, this version, because the length of connector 3 on left and right direction is bigger, therefore, when can provide stronger cushion effect, can provide stronger quick startup ability, be applicable to strenuous exercise the rear portion of heel.
As shown in Figure 9, it is up-small and down-big round table-like that the profile of connector 3 is, preferably, the middle part of round platform has necking part, the dual-side of this necking part is the arc of indent on longitudinal profile, and in the present embodiment, the height of connector 3 is 1-1.5cm, the diameter of round platform upper surface is 4cm, and the diameter of lower surface is 4.5cm.This version combines the advantage of two kinds of schemes among the embodiment 5, and bradyseism power is soft, and the ability that starts fast is moderate, and motion such as be specially adapted to jog.
Damping device among the present invention carries out the bradyseism structural design according to the aufbauprinciple of I-beam, and I-beam refers to that cross-sectional form is the beam of I type, and the wing plate above it is called the top flange, and following wing plate is called the lower flange, and the plate that connects two edges of a wing is called web.Becoming that flange width does not wait up and down do not wait wing I type beam, and the I ellbeam has girder steel, reinforced beam and prestressed steel reinforced concrete beam.Wing I type beam is not waited greater than the lower flange in both general top flanges, back.I-beam is widely used on the architecture, as overpass etc., has mechanical stability.Its nucleus is big, and the effective range that deformed bar is arranged is big, and the section material utilization is comparatively effective, and it is little to conduct oneself with dignity, and can resist bigger twisting action, is usually used in the large span highway bridge.Web has certain thickness, makes member have enough shear capacities, and is convenient to concrete building.The present invention is connected to form upper and lower arc in two ends up and down with the last lower flange of I-beam, last arc top has the cup-shaped support, be used for and the spring heel coupling, the stability of control heel, the forward and backward two ends of upper and lower arc link the one-level bradyseism system that is formed as one respectively; Clipping material between the upper and lower arc is the high resilience polyurethane resin shock suction body of polyurethane resin, form level 2 buffering shock-absorbing system, arc lower plate bottom is provided with sheet TPU shock-absorbing elastomer, forms three grades of bradyseism systems, has improved the bradyseism effect of sport footwear greatly.
The present invention is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or close technical scheme with the present invention, all falls within protection scope of the present invention.
