Description

Technical Field

[0001] The invention relates to the technical field of soles, and in particular to a sole support component, a sole and a shoe. Background Art

[0002] Shoes are what the feet wear during walking, running and competitive sports, and include an upper and a sole fixed to the upper. When wearing shoes, the foot is located between the upper and the sole, and the sole is located below the upper and the foot and above the ground. It is the carrier for the foot to act on the ground, and also the bridge for the ground to react on the foot. In order to pursue the comfort of the foot, the sole is usually provided with a shock-absorbing component, such as an air cushion, that is, a capsule containing pressurized gas. Since the pressurized gas is enclosed in the capsule, the capsule has an expansion characteristic due to the gas pressure. It can be appropriately compressed to absorb energy to achieve a shock-absorbing effect. It can also withstand a certain external pressure due to the existence of the internal gas pressure, achieving the effect of support and energy return. However, when the air cushion is subjected to greater pressure, or is punctured, aged or due to other reasons, it is easy to cause the capsule to rupture, the gas in the capsule to leak, and the air cushion loses its shock-absorbing and support functions for the sole.

[0023] The nineteenth technical solution relates to a sole, which is provided with an inner cavity, and includes the sole support component described in any one of the first to nineteenth technical solutions, wherein the sole support component is adapted in the inner cavity, and the inner cavity is provided with an upper surface and a lower surface, the outer surface of the top wall of the bladder is connected to the upper surface of the inner cavity of the sole, and the outer surface of the bottom wall of the bladder is connected to the lower surface of the inner cavity of the sole.

[0026] The twenty-second technical solution relates to a shoe, which comprises a sole as described in any one of the nineteenth to twenty-first technical solutions and an upper connected to the sole, wherein the sole and the upper enclose a space suitable for the foot to wear.

[0027] Compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0028] The applicant has learned through continuous observation, experimentation and research that the sole, as an important medium for the foot during exercise, will be provided with a component with a shock-absorbing effect, such as an air cushion, that is, a capsule containing pressurized gas. After the air cushion is provided on the sole, due to the expandable characteristics of the capsule and the presence of pressurized gas in it, the air cushion has a supporting and shock-absorbing effect. However, the applicant found that the initial air pressure in the capsule is relatively large. When the sole is subjected to a large external pressure, the capsule may rupture due to excessive local pressure; when the initial air pressure in the capsule is relatively small, the support function and energy return performance of the air cushion are very poor, and it is not suitable for exercise. In addition, the capsule is prone to aging or puncture, resulting in the complete loss of the shock-absorbing and support functions of the air cushion. Therefore, after the applicant has observed the above defects of the air cushion for a long time, he creatively proposed the idea of ​​adding a support member to the capsule. On the one hand, it can make full use of the compressibility of the fluid in the capsule to exert its shock-absorbing function, and on the other hand, it can avoid its easy rupture and poor energy return performance, forming a sole support component with excellent shock-absorbing, support and energy return performance.

[0029] The applicant also found that the sole needs to have the performance of support and energy return, and the force needs to be dispersed in multiple directions to obtain reaction forces in multiple directions, which is beneficial to support; the dispersed force is aggregated into a force in a specific direction, which is beneficial to obtain energy return and movement. Then the process of dispersing and then aggregating the force is the key to achieving the stable support function and good movement performance of the support. Therefore, designing the corresponding structure to achieve the above force transmission process is the core of solving the technical problem of the support having a stable support function and good movement performance.

[0030] In the first technical solution, the support member in the capsule is equivalent to providing a bracket for the capsule, which improves the pressure bearing capacity of the sole support assembly. Even if the capsule is subjected to a large local pressure transmitted by the foot, the capsule is not easily damaged; the pressurized fluid in the capsule and the support member jointly support the top and bottom walls of the capsule, sharing the pressure, thereby extending the service life of the sole support assembly. Even if the capsule is ruptured and the pressurized fluid in the capsule leaks, the sole support assembly still has the supporting and shock absorbing functions of the support member.

[0031] In the structural setting of the support member, since the projection of each first support part and the projection of each second support part do not overlap on the projection plane perpendicular to the up and down direction, the projection of at least three adjacent second support parts are evenly distributed around the projection of part of the first support part, and the first support part is connected to each adjacent second support part through the first support arm, and the projection of at least three adjacent first support parts are evenly distributed around the projection of part of the second support part, and the second support part is connected to each adjacent first support part through the first support arm. Therefore, after the part of the second support part receives the force transmitted from the top wall of the capsule, it is transmitted to at least three adjacent first support parts through at least three first support arms, so that the force is dispersed, and at least three first support arms support the second support part, which plays a role of stabilizing support for the second support part, thereby providing stable support for the foot. The projection of at least three adjacent second support parts is evenly distributed around the projection of part of the first support part, and the first support part is connected to each adjacent first support part through the first support arm, so that the force aggregation is realized, and a better ground reaction force can be obtained to improve the sports performance of the sole.

[0032] In the second technical solution, the projection of the connection point on the same first support arm connected to the first support part does not overlap with the projection of the connection point on the second support part, that is, the first support arm is arranged to be inclined in the up and down directions, so that the up and down force received by the second support part can be converted into a force inclined in the up and down directions, thereby decomposing the force inclined in the up and down directions into horizontal forces and up and down forces, achieving force dispersion and force offset, and enhancing the supporting function of the support member.

[0033] In the third technical solution, a line connecting the projection of a connection point on the same first support arm connected to the first support portion and a line connecting the projection of a connection point on the same first support arm connected to the second support portion extends from the connection point of the first support portion toward a direction away from the first support portion, that is, the first support arm extends obliquely outward from the first support portion to the second support portion, which is beneficial to the spatial arrangement of the first support portion, the second support portion and the first support arm compared to extending obliquely inward to the second support portion, and more first support portions, second support portions and first support arms are arranged in the same space, thereby further improving the supporting function of the support member.

[0034] In the fourth technical solution, a structure of four first support arms is adopted. After the second support part is subjected to force, the force is transmitted to the four adjacent first support parts through the four first support arms, so as to achieve better force dispersion. In addition, the four first support arms support the second support part, which plays a role of stabilizing the second support part, thereby providing stable support for the foot. The projection of at least four adjacent second support parts is evenly distributed around the projection of part of the first support part. The second support part is connected to each adjacent first support part through the first support arm, which achieves better force aggregation, so as to obtain better ground reaction force and improve energy return performance.

[0035] In the fifth technical solution, since the four first support arms connected to the same first support portion are arranged orthogonally relative to each other, the first support portion and the second support portion are symmetrical in the force direction, so that the force is dispersed more evenly, the supporting force is more balanced, and a more stable supporting effect is achieved.

[0036] In the sixth technical solution, on the projection plane perpendicular to the up-down direction, the projection of part of the first support part is evenly distributed around the projection of six adjacent second support parts, and the first support part is respectively connected to each adjacent second support part through the first support arm, and the projection of part of the second support part is evenly distributed around the projection of three adjacent first support parts, and the second support part is connected to each projection of the adjacent first support part through the first support arm. Therefore, compared with the support member of the first technical solution, the first support part occupies a larger space, has better integrity, and has a better supporting effect on the second support part. Relatively speaking, the second support part is more fragmented, which is more conducive to the dispersion of force and has better stability.

[0037] In the seventh technical solution, the third support part is located above the fourth support part and below the second support part; on the projection plane perpendicular to the up-down direction, the projection of each third support part does not overlap with the projection of each fourth support part, and the projection of four adjacent second support parts is evenly distributed around the projection of part of the third support part, and the third support part is connected to the second support part adjacent to each projection through the second support arm, and the projection of four adjacent second support parts is evenly distributed around the projection of part of the fourth support part, and the fourth support part is connected to the second support part adjacent to each projection through the third support arm, and the projection of two third support parts and two fourth support parts are evenly distributed around the projection of part of the second support part, and the second support part is connected to the third support part adjacent to each projection through the second support arm, and is connected to the fourth support part adjacent to each projection through the third support arm. In this structural setting, the second support part, the third support part, and the fourth support part are staggered in the up-down direction, and an additional layer of support platform is added, so that the space is fully utilized to set the support structure, the structural density in the unit space is improved, and the force dispersion effect and the overall support effect are further improved. While stabilizing the support, more support structures also bring more elastic deformation, and the shock absorbing effect of the support member is also enhanced.

[0038] In the eighth technical solution, since the third support portion is connected to the fourth support portion adjacent to each projection through the fourth support arm, further support arms are provided to better achieve force dispersion transmission and elastic deformation, thereby enhancing the supporting and shock-absorbing effects of the support member.

[0039] In the ninth technical solution, the two second support arms connected to the same second support part are arranged facing each other, and the two third support arms are arranged facing each other, and the second support arm and the third support arm of the second support part are arranged orthogonally, so that the second support part is symmetrical in the force direction, achieving more uniform force dispersion and more balanced supporting force, and the support member can achieve a more stable supporting effect.

[0040] In the tenth technical solution, the projections of the second supporting portion, the third supporting portion, and the fourth supporting portion are arranged at equal intervals, which is beneficial to the spatial arrangement of the supporting members and the balanced force of each supporting portion.

[0041] In the eleventh technical solution, the fourth support arm is arranged to be inclined in the up and down directions, so that the up and down force received by the fourth support part can be converted into a force inclined in the up and down directions, thereby partially decomposing the force inclined in the up and down directions into a horizontal force, thereby achieving force dispersion and force offset, and enhancing the supporting function of the support member.

[0042] In the twelfth technical scheme, a line connecting the projection of a connection point of the same fourth support arm connected to the third support portion and the projection of a connection point connected to the fourth support portion extends from the connection point of the third support portion toward away from the third support portion, that is, the fourth support arm extends obliquely outward from the third support portion to the fourth support portion, which is beneficial to the spatial arrangement of the third support portion, the fourth support portion and the fourth support arm, compared to extending obliquely inward to the fourth support portion, and enhances the supporting function of the support member.

[0043] In the thirteenth technical solution, the third support arm and the fourth support arm are arranged at intervals on the fourth support portion, which is beneficial to spatial arrangement and force balance, and improves the stability of the support member.

[0044] In the fourteenth technical solution, the projections of four second support arms and four third support arms connected to the same third support part are arranged at intervals around the projection of the third support part, which is beneficial to the balanced force of the third support part and the spatial arrangement of the second support arms and the third support arms.

[0045] In the fifteenth technical solution, the second support arm is connected to the upper end surface of the third support portion, and the fourth support arm is connected to the lower end surface of the third support portion, thereby enhancing the force bearing capacity and force balance of the third support portion.

[0046] In the sixteenth technical solution, the shape of the second support arm is conducive to forming an avoidance space while being inclined in the up-down direction. Because the second support arm connects the second support part at the top and the fourth support part at the bottom, only the middle section is inclined, which facilitates the demoulding manufacturing of the support member of the present application in a mold-matching form.

[0047] In the seventeenth technical solution, the first support part is fixedly connected to the inner surface of the bottom wall of the capsule, and the second support part is fixedly connected to the inner surface of the top wall of the capsule. On the one hand, the fixed connection between the support member and the top and bottom walls of the capsule is conducive to restraining the capsule, limiting its expansion and deformation, increasing the ability of the capsule to withstand the pressure of the fluid inside it, and not easy to rupture; on the other hand, there are parts of the top and bottom walls of the capsule that are not fixedly connected to the support member, that is, the gap part between each second support part and the gap part between each first support part. This part is not pulled by the support member 1 and expands under the pressure in the capsule. This part slightly protrudes from the fixed connection part. When the foot applies force to the capsule, these parts will be the first to be deformed by force, thereby providing a better shock-absorbing effect for the foot. Further, after the above-mentioned expanded part is compressed, the pressurized fluid in the capsule and the support member work together to provide support, shock absorption and energy return for the sole. The fixed connection method is adopted, which is easy to process and solidify, and the connection is more stable.

[0048] In the eighteenth technical solution, the technical effect is the same as that of the seventeenth technical solution.

[0049] In the nineteenth technical solution, the sole provided with the above-mentioned sole support assembly has the functions and effects as described above, and the sole support assembly is connected in abutting manner with the inner cavity of the sole, which is convenient for installation.

[0050] In the twentieth technical solution, the sole support assembly is fixedly connected to the inner cavity of the sole, which can better position and restrain the bladder, avoid wear on the outer wall of the bladder, and extend the service life of the sole support assembly.

[0051] In the twenty-first technical scheme, a groove is formed in the middle part of the outer surface of the top wall of the bladder body, which is conducive to achieving a fixed connection between the top wall of the bladder body and the inner cavity of the sole by applying adhesive. The connection is firm and there is no glue overflow. A U-shaped groove is formed on the side of the bladder body and passes through the upper and lower directions. A convex part adapted to the U-shaped groove is provided in the inner cavity of the sole, which is convenient for positioning and installing the sole support component.

[0052] In the twenty-second technical solution, the shoe using the sole containing the sole support assembly as described above has the functions and effects of good support, mobility and comfort. BRIEF DESCRIPTION OF THE DRAWINGS

Fig.13The structural schematic diagram of the support member 1 of the present embodiment is shown, that is, the projection schematic diagram of the support member 1 of the present embodiment on the projection plane perpendicular to the up and down direction.

The lower end surfaces of several fourth support portions 6 together form a surface suitable for connecting with the inner surface of the capsule bottom wall 13 to abut against and support the capsule bottom wall 13 .The support member 1 further includes a first support arm 4 and a fourth support arm 9, wherein the first support arm 4 includes a second support arm 7 and a third support arm 8, each second support portion 3 is connected to each third support portion 5 adjacent to its projection through the second support arm 7, and is connected to each fourth support portion 6 adjacent to its projection through the third support arm 8, each second support portion 3 is connected to each third support portion 5 adjacent to its projection through a second support arm 7, and each fourth support portion 6 adjacent to its projection is also connected through a third support arm 8.

Each third support portion 5 is connected to each second support portion 3 adjacent to its projection through the second support arm 7, and is connected to each fourth support portion 6 adjacent to its projection through the fourth support arm 9. Each third support portion 5 is connected to each second support portion 3 adjacent to its projection through a second support arm 7, and is connected to each fourth support portion 6 adjacent to its projection through a fourth support arm 9. In this way, four second support arms 7 and four fourth support arms 9 are connected to the non-edge third support portion, and the projections of the four second support arms 7 and the four fourth support arms 9 connected to the same third support portion 5 are evenly spaced around the projection of the third support portion 5, and the second support arm 7 is connected to the upper end surface of the third support portion, and the fourth support arm 9 is connected to the lower end surface of the third support portion. The projections of the connection points of the same fourth support arm 9 with the third support portion 5 and the fourth support portion 6 on the projection plane perpendicular to the up-down direction do not overlap, and the connecting line of the projections of the two connection points extends from the third support portion 5 to the fourth support portion 6 in the direction away from the third support portion 5, that is, the second support arm 7 is arranged obliquely to the up-down direction. Each fourth support portion 6 is connected to each second support portion 3 adjacent to the projection through the third support arm 8, and is connected to each third support portion 5 adjacent to the projection through the fourth support arm 9. Each fourth support portion 6 is connected to each second support portion 3 adjacent to its projection through a third support arm 8, and is connected to each third support portion 5 adjacent to its projection through a fourth support arm 9. Each fourth support portion 6 is connected to each second support portion 3 adjacent to its projection through a third support arm 8, and is connected to each third support portion 5 adjacent to its projection through a fourth support arm 9.In this way, four third support arms 8 and four fourth support arms 9 are connected to the non-edge fourth support portion, and the projections of the four third support arms 8 and the projections of the four fourth support arms 9 connected to the same fourth support portion 6 are arranged at intervals around the projection of the fourth support portion 6.

[0094] The sole support assembly 10 of the present application first forms the capsule 11 and the support member 1 separately, and then places the support member 1 in the capsule 11, the upper end surface of the second support portion 3 is connected to the inner surface of the capsule top wall 12, and the lower end surface of the fourth support portion 6 is connected to the inner surface of the capsule bottom wall 13. In this embodiment, the connection method is a fixed connection, and the upper end surface of the second support portion 3 is fixedly connected to the inner surface of the capsule top wall 12 by bonding, and the lower end surface of the fourth support portion 6 is fixedly connected to the inner surface of the capsule bottom wall 13. In other embodiments, the connection method can be a non-fixed connection, and it is only necessary to meet the requirements that the support member 1 is properly limited in the capsule 11 and does not flip, and the gap between the upper end surface of the second support portion 3 and the inner surface of the capsule top wall 12 is not too large, so that the support member 1 can play the role of supporting the capsule 11 and then supporting the sole. The fixed connection method can also be bonding, hot melting, welding, etc. After the support member 1 is arranged in the bladder 11, nitrogen is filled into the bladder 11, and the bladder 11 is sealed after the bladder 11 reaches the set pressure. The bladder 11 can also be sealed by bonding, hot melting, welding, etc. Since the upper end surface of the second support portion 3 is fixedly connected to the inner surface of the bladder top wall 12, and the lower end surface of the fourth support portion 6 is fixedly connected to the inner surface of the bladder bottom wall 13, the support member 1 is fixedly connected to the bladder top wall 12 and the bottom wall 13. When the bladder 11 expands under the action of air pressure, the support member 1 plays a role in limiting the expansion of the bladder 11 in the up and down directions, which is equivalent to the support member 1 pulling the top wall 12 and the bottom wall 13 of the bladder 11. On the one hand, the pressure bearing capacity of the bladder 11 is improved, and a higher air pressure can be filled in the bladder 11, which improves the support and energy return performance of the inflatable bladder 11 for the sole. On the other hand, the strength of the bladder 11 is strengthened, and the service life of the inflatable bladder 11 is extended.

[0095] After the sole support assembly 10 is formed, it is installed in the inner cavity of the sole, the capsule top wall 12 is connected to the upper surface of the inner cavity of the sole, and the capsule bottom wall 13 is connected to the lower surface of the inner cavity of the sole. This embodiment adopts a bonding method to fix the connection. Among them, a groove is formed in the middle of the outer surface of the capsule top wall 12, which is conducive to bonding with the inner cavity of the sole by applying adhesive, and the connection is more firm and does not produce glue overflow. A U-shaped groove is formed on the side of the capsule 11 that runs through the upper and lower directions, which is conducive to the limited cooperation with the convex part adapted to the U-shaped groove set in the inner cavity of the sole, and is convenient for positioning and installation. After the sole support assembly 10 is assembled in the inner cavity of the sole, when the foot applies force to the sole during wearing, the upper surface of the inner cavity of the sole transmits the force to the capsule 11. Since the upper end surface of the second support portion 3 in this embodiment is fixedly connected to the inner surface of the capsule top wall 12, and there is still a gap between each second support portion 3, that is, there is a part of the capsule top wall 12 that is not fixedly connected to the support member 1. This part is not pulled by the support member 1 and expands under the action of the air pressure in the capsule 11. This part slightly protrudes upward from the part fixedly connected to the second support portion 3. Similarly, the part of the capsule bottom wall 13 that is not fixedly connected to the fourth support portion 6 slightly protrudes downward from the part fixedly connected to the fourth support portion. In the process of force, the above two parts are first compressed and deformed, which plays a role in cushioning the sole. When the compression deformation reaches a certain amount, the part of the capsule 11 fixedly connected to the second support portion 3 begins to be stressed. From this time on, the enclosed gas in the capsule 11 and the support member 1 jointly bear the force transmitted from the sole. Therefore, compared with the technical solution in which the support member 1 is not provided in the bladder 11, on the first aspect, the pressure bearing capacity of the bladder 11 is improved, and the service life of the inflatable bladder 11 is increased; on the second aspect, even when the bladder 11 is broken and the air pressure cannot play a role, the sole support assembly 10 of the present application can still provide support, shock absorption and energy return performance for the sole. On the third aspect, compared with the air cushion, due to the good gas fluidity, its support stability is poor, and under the action of the support member 1, the sole support assembly 10 of the present application has better support and energy return performance. Specifically, in the process of the support member 1 being subjected to force, after the second support part 3 is subjected to force, the second support part 3 transmits the force to the third support part 5 through the second support arm 7, and transmits the force to the fourth support part 6 through the third support arm 8. Since the second support arm 7 and the third support arm 8 connected to the same second support part 3 are arranged orthogonally relative to the second support part 3, on the one hand, the second support arm 7 and the third support arm 8 stably support the second support part 3 to provide stable support for the foot and avoid twisting; on the other hand, the force on the upper end surface of the second support part 3 will be evenly dispersed, and since the second support arm 7 and the third support arm 8 are inclined rigid connecting rods, the vertical force exerted on the second support part 3 will be partially converted into horizontal force, effectively weakening the transmission of vertical force.Similarly, after the third support part 5 is subjected to force, the force is transmitted to the fourth support part 6 through the fourth support arm 9. The fourth support arm 9 is also an inclined rigid connecting rod, which further converts the force into horizontal and vertical forces acting on the fourth support part 6. The second support arm 7 and the fourth support arm 9 connected to the same third support part 5 are evenly spaced, and the horizontal force acting on the same third support part 5 can be partially offset. The third support arm 8 and the fourth support arm 9 connected to the same fourth support part 6 are also evenly spaced, and the horizontal force is further partially offset, further reducing the horizontal force, so that the force transmitted by the fourth support part 6 to the bottom wall 13 of the capsule is reduced, and the force of the ground reacting on the sole is reduced, effectively reducing the force of the ground reacting on the foot, and improving the comfort of the foot. In addition, the same third support portion 5 not at the edge is connected to a plurality of second support arms 7 and fourth support arms 9 that are spaced apart, and the same fourth support portion 6 not at the edge is connected to a plurality of third support arms 8 and fourth support arms 9 that are spaced apart and evenly distributed, which can provide stable support for the third support portion 5 and the fourth support portion 6, thereby providing stable support for the sac 11 and even the sole.

Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
