RELATED APPLICATIONS

[00011 This application claims the benefit of priority to Chinese Patent Application No. 201320404365.1, filed on July 9, 2013, which is hereby incorporated by reference in its entirety.

HELD OF THE INVENTION

100021 The invention relates in general to a buffering structure, and more particularly to an insole anti-shock pressure reducing and buffering structure, which has a buffer that can be risen or depressed with different heights in response to different magnitudes of reaction forces, and can rapidly distribute and absorb difibrent pressures borne by front and rear portions of foot during walking, running and jumping, as well as generate air flows at an internal bottom of a shoe body.

BACKGROUND OF THE INVENTION

[00031 Most people wear shoes to protect their feet from hurt, a ground reaction force is produced during walking, running, or jumping due to the weight of the person, and the reaction force borne by the foot may be amplified from one to several times when transferred to the knee. However the conventional shoe is only provided with a pad at an internal bottom thereof for the purpose of comfortable and softer. Due to the sole of the shoe is incompressible which may not be adjusted upward or downward varying with the different forces endured during people is walking, running and jumping with wearing this shoe. Further,

I

the ground reaction force can not be distributed and absorbed, thus there is not buffering and protection at all, and the reaction force will be directly transferred from the foot to the knee and hurt the knee seriously. Although an air-cushioned shoe has been developed recently, however, at best, the structure of the air-cushioned shoe is a chamber full filled with air. A pair of shoes would lose the air protection fluiction as long as the chamber is pierced by small stones or other foreign matter. In addition, the sole of this air-cushioned shoe is incompressible when bearing a force exerted by foot due to the height of the air cushion is fixed, can not generate different adjustments in response to different reaction forces borne by foot, and can not distribute and absorb different pressures borne by the sole, which causes the feet and the knees easily to be hurt by shocking.

Furthermore, no air flows are generated in the insole of the conventional shoe, which causes that the heat produced by feet can not convect with the outer air, so it is easy to produce stuffiness and odor, thereby reducing the practicability of the shoe. The drawbacks above are breakthroughs that people in this art and consumers are eager to make. In view of this point, the inventor provides an insole anti-shock pressure reducing and buffering structure, which can be risen or depressed with different heights in response to different magnitudes of the reaction forces, and can rapidly distribute and absorb different pressures borne by front and rear portions of foot during walking, running and jumping, as well as generate air flows at an internal bottom of a shoe body such that the effects of shock absorbing, pressure releasing, and buffering of the shoe are greatly enhanced in addition to the improved wearing comfort and air flows of the shoe body.

However the conventional shoe is only provided with a pad at an internal bottom thereof for the purpose of comfortable and softer. Due to the sole of the shoe is incompressible which may not be adjusted upward or downward varying with the different forces endured during people is walking, running and jumping with wearing this shoe. Further, the ground reaction force can not be distributed and absorbed, thus there is not buffering and protection at all, and the reaction force will be directly transferred from the foot to the knee and hurt the knee seriously. Although an air-cushioned shoe has been developed recently, however, at best, the structure of the air-cushioned shoe is a chamber full filled with air. A pair of shoes would lose the air protection function as long as the chamber is pierced by small stones or other foreign matter. In addition, the sole of this air-cushioned shoe is incompressible when bearing a force exerted by foot due to the height of the air cushion is fixed, can not generate different adjustments in response to different reaction forces borne by foot, and can not distribute and absorb different pressures borne by the sole, which causes the feet and the knees easily to be hurt by shocking. Furthermore, no air flows are generated in the insole of the conventional shoe, which causes that the heat produced by feet can not convect with the outer air, so it is easy to produce stuffiness and odor, thereby reducing the practicability of the shoe.

10044] The shoe body 1 is provided with a concave portion 11! on an internal bottom ii thereof [0045] The buffer 2 is disposed in the concave portion iii defined in the internal bottom ii of the shoe body' 1, the buffer 2 includes an upper layer plate 21, a lower iaye.r plate 22, multiple interrai springs 23, and multiple external springs 24. Wherein, the upper layer plate 21 has an upper connecting block 210 disposed under a middle part of the upper layer plate 21 and multiple upper sleeve blocks 211 separately disposed under a front part and a rear part of the upper layer plate 21, fixed space 2110 is formed at the center of each upper sleeve block 211.

Further, the upper layer plate 21 of the invention has a plurality of perforations 212 formed therein, Preferably, the upper sleeve block 211 of the tipper layer plate 21 of the invention is in a shape of a cylinder or an arc, hut not limited to these shapes, it also can be a shape functionally equivalent to the cylinder or the arc, all of the shapes are nc1uded within the spirit and scope of the invention. I lie lower layer plate 22 disposed below the upper layer plate 21 has a lower connecting block 220 disposed on a middle part of the lower layer plate 22 corresponding to the upper connecting block 210 of the upper layer plate 21 and multiple lower sleeve blocks 221 separately di sposed on a fi'ont part and a rear part of the lower layer plate 22 corresponding to the upper sleeve blocks 71 1 of the upper layer plate 21, fixed space 2210 is formed at the center of each lower sleeve block 221.

Further, the lower layer plate 22 of the invention has a plurality of perforations 222 formed therein, preferably, the lower sleeve block 221 of the invention is in a shape of a cylinder or an arc, but not limited to these shapes, it also can be a shape functionally equivalent to the cylinder or the arc, all of the shapes are included within the spiril and scope of die invention. The multiple iniernal springs 23 are separately disposed in the fixed spaces 2110, 2210 of the upper sleeve block 211 of die upper layer plate 21 and the corresponding lower sleeve block 221 of the lower layer plate 22; and the niultipie external springs 24 are separately disposed outside th.e upper sleeve block.. 211 of th.e upper layer plate 21 and th.e corresponding lower sleeve block 221 of the lower layer plate 22. The diameter of the internal springs 23 is sin. .aliei than that of the external springs 24, while the wire diameter of the internal springs 23 is smaller than that of the extenia.l springs

S

24 and the number of turns of the internal springs 23 is more than that of the external springs 24, so that the invention can generate different effects depending on different forces. Further, a pad3 with perforations 31 is disposed on the buffer 2 of the invention (as shown in Fig. 4).

[00461 Referring to Figs. 5-7, Fig. 5 shows a first embodiment of the invention interacting with foot, Fig. 6 shows a second embodiment of the invention interacting with the foot, Fig. 7 shows a third embodiment of the invention interacting with the foot. The assembly of the invention is easy, and just need to place the buffer 2 in the concave portion 111 defmed in the internal bottom 11 of the shoe body 1, due to the concave portion Ill is deposed on the internal bottom 11 of the shoe body land the buffer 2 is deposed in the concave portion 111 so that the buffer 2 can not be seen from the outside of the shoe body 1, thereby the appearance thereof would not be affected. When used, the user just need to directly put foot on the buffer 2 of the upper layer plate 21 (as shown in Figs. 1-3, and Fig. 5) or on the pad 3 deposed on the buffer 2 (as shown in Fig. 4). A front part of the upper layer plate 21 is compressed downward when a pressure is borne by the front portion of the foot 4 (as shown in Fig. 6), wherein the multiple internal springs 23 with smaller wire diameter, more number of turns and smaller diameter firstly react to be compressed for a smaller reaction force, as the multiple internal springs 23 has been compressed 1:0 a limit, the multiple external springs 24 with larger wire diameter, less number of turns and larger diameter then also be compressed for a larger reaction force, thereby a strong buffering is produced by compressed external springs 24 together with the compressed internal springs 23.

Thus, the buffer 2 can adjust at any time for different reaction forces at different stages. When the rear part of the foot 4 bears a force, the rear part of the upper layer plate 21 is also compressed downward (as shown in Fig. 7), and the function of the structure is the same as Fig. 6. Furthermore, since the upper layer plate 21 and the lower layer plate 22 are provided with perforations 212, 222, as the buffer 2 of the invention is subject to forces to bring about ascending and descending compression, air flows are generated at the shoe body 1 (as shown in Figs.5, 6, and7).

[0047] Based on the structure, the huller 2 disposed on the internal bottom II of the shoe body I can be risen or depressed with different heights in response to different magnitudes of the reaction forces, and can rapidly distribute and absorb differeni pressures borne by front and rear portions of foot 4 during walking, running and jumping, as well as generate air flows at the nternai bottom ii of the shoe body I such that the effects of shock absorbing, pressure rdeasing, and buffering are greatly enhanced in addition to the improved wearing comfort and air flows of the shoe body 1 1n sum, the invention has broken through the structure of the prior art, and achieved the prospective advantages in addftion that it is not so easy for the ordinary skilled in the art to think of.

[0048] While the invention ha.s been described in connection with what are presently considered to he the most practical and preferred embodiments, it is to he understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
