Description

Shoes with rebound energy

The invention relates to a sole rebound structure capable of generating rebound force, in particular to a shoe with rebound energy.

Referring to FIG. 1, a shoe 1 with a stabilizing element disclosed in US Publication No. 20010001907 patent case mainly includes a sole 11 and a stabilizing element 12. The sole 11 includes a forefoot area 111 and a heel area 112. The stabilizing element 12 is made of elastic material, and includes a forefoot portion 121 filled in the front palm area 111 of the sole 11, and a heel portion 122 filled in the heel area 112 of the sole 11 and capable of releasing energy after deformation .

When the foot is running or walking, the heel will be applied to the forefoot 121 of the stabilizing element 12 with the forefoot of the foot during the process of being off the ground, so that the heel 122 of the stabilizing element 12 will bend toward the heel. It deforms and generates rebound energy to advance the heel. In this way, the energy loss of the feet during running or walking is reduced, and the effect of labor saving is achieved.

However, since the heel portion 122 of the stabilizing element 12 extends to the heel area 112 of the sole 11, in the case of a longer length and a larger structural surface area, the heel portion 122 Often it is not easy to flex, or the deformation range is not large enough, so that the energy during rebound is insufficient, and the effect of labor saving is greatly reduced.

Another type of shoe with elastics, as disclosed in the US Patent No. 5,572,805, discloses that a shoe sole is filled with two or more elastics of different densities. In this way, when the feet are running or walking, the elastics provide a cushioning effect.

However, the aforementioned elastics can only provide a cushioning effect, and cannot push the heel. What is important is that these elastics are separated from the forefoot by a very large distance. Therefore, the center of pressure when the foot is running or walking It just falls within the distance and cannot effectively press on the elastics, so that the position of the elastics relative to the heel cannot be used to push the heel.

Therefore, the purpose of the present invention is to provide a shoe with rebound energy that can generate more rebound energy and effectively improve labor saving efficiency.

Therefore, the shoe with rebound energy of the present invention includes a sole and a sole rebound structure.

The sole includes a forefoot area and a heel area spaced apart, and an arch area connected between the forefoot area and the heel area.

The sole rebound structure is used to generate rebound and push up the energy of the sole, and includes two flexible sheets connected to the sole and arranged side by side. A length direction of the sole extends from the forefoot area toward the arch area and does not exceed the junction between the arch area and the heel area. Each flexible sheet includes a medial edge, and the inner sides of the flexible sheets Fate together defines a gap.

The effect of the present invention is that the repulsive structure of the sole of the foot is divided into two through the gap, so that when the sole of the foot moves and bears a pressure, it is easier to flexibly deform, and generates more rebound energy to push the sole of the foot, reducing the The energy loss when the sole of the foot is exerted effectively improves the efficiency of labor saving, making the sole of the foot move more effortlessly.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are represented by the same numbers.

Referring to FIGS. 2, 3 and 4, a first embodiment of the shoe with rebound energy of the present invention is in contact with a sole 2. The sole 2 includes a forefoot 21 and a back The heel 22 and an arch 23 between the forefoot 21 and the heel 22 of the foot. The shoe includes a sole 3 and a sole rebound structure 4.

It is worth noting that the following description of the direction is based on the direction of the forefoot 21 as the front and the direction of the heel 22 as the rear. The right-hand direction in FIG. 2 is the right side and the left-hand direction is the left side.

The sole 3 is suitable for bearing a pressure from the sole 2 and includes a forefoot area 31 suitable for contacting the forefoot 21 of the foot, and a heel spaced apart from the forefoot area 31 and suitable for contacting the heel 22 Zone 32, connected between the forefoot zone 31 and the heel zone 32 and suitable for a foot arch zone 33 opposite to the arch of the foot 23, suitable for a top surface 34 facing the sole of the foot 2, opposite to the top surface 34 A bottom surface 35 and a peripheral surface 36 connecting the top surface 34 and the bottom surface 35.

The sole rebound structure 4 includes two flexible sheets 41 defining a gap 40.

In this embodiment, the flexible sheets 41 are aligned with each other in a left and right arrangement along a length direction X of the sole 3, and each flexible sheet 41 is fitted on the top surface 34 of the sole 2, and Partly exposed on the top surface 34, and has a medial edge 411 extending from the forefoot region 31 toward the arch region 33 and extending to the junction of the arch region 33 and the heel region 32, opposite to the medial side Rim 411 and an outer edge 412 spaced apart from the inner edge 411, a front edge 413 connected to a front end of the inner edge 411 and a front end of the outer edge 412, a rear end connected to the inner edge 411 and the outer edge A rear edge 414 of a rear end of 412 is connected between the front edge 413, the inner edge 411 and the outer edge 412 and is opposite to A pressure receiving portion 415 of the forefoot region 31 and a flexible portion 416 connected between the rear edge 414, the pressure receiving portion 415, the inner edge 411 and the outer edge 412. The outer edge 412 has a number of grooves 417. The grooves 417 can be linear, arc, zigzag, or the like.

It should be noted that the flexible sheets 41 are not limited to being partially exposed on the top surface 34. In other variations of this embodiment, they can also be partially exposed on the bottom surface 35, or partially exposed on the peripheral surface 36, Or it is completely filled inside the sole 3.

The inner edges 411 of the flexible sheets 41 jointly define the gap 40. The gap 40 is equidistant and is between 0 mm and 50 mm. The gap 40 extends along a line of force L formed by the center of the pressure. In this embodiment, the trajectory line of force L is an arc, so the gap 40 extends along the arc.

It should be noted that the trajectory line of force L is not limited to an arc. In other variations of this embodiment, it can also meet functional requirements such as running or walking, and as shown in FIG. 6, it is a straight line.

In addition, the surface area of the one flexible sheet 41 is not greater than the surface area of the other flexible sheet 41. In this embodiment, the surface area of the one flexible sheet 41 is approximately the same as the surface area of the other flexible sheet 41. .

It should be noted that the surface area of the flexible sheets 41 is not limited to those shown in Figures 2 and 6, but is approximately the same. In other variations of this embodiment, it can also be as shown in Figure 7. The surface area of 41 is smaller than the surface area of the flexible sheet 41 on the right, or as shown in FIG. 8, the surface area of the flexible sheet 41 on the right is smaller than that of the flexible sheet 41 on the left. area.

Refer to Figures 2, 4 and 5, whereby when the sole of the foot 2 is running or walking, when the heel 22 is stepped on, the forefoot 21 of the foot is applied to the flexible sheet 41 The pressure-receiving part 415 is flexed and deformed by the flexible sheets 41. At this time, the part with the largest flexural deformation will be in the pressure-receiving part 415, and then, in the process of leaving the ground, due to the pressure of stepping Disappear, the flexible sheets 41 will rebound due to the elastic restoring force after deformation and push up the energy of the sole 2 of the foot. Taking the compressed portion 415 with the largest deformation amplitude as an example, the rebound generated by the compressed portion 415 The energy can just further advance the forefoot 21 that is leaving the ground, so that the forefoot 21 can move upward with less effort. In this way, the energy loss of the feet during running or walking is reduced, and the effect of labor saving is achieved.

Since the sole rebound structure 4 is divided into two to form two flexible sheets 41 separated by the gap 40, the pressure required to bend each flexible sheet 41 is reduced, and the pressure can be lowered. The flexible portion 416 of each flexible piece 41 is more easily deformed and generates more rebound energy.

Referring to FIG. 2, furthermore, since the flexible sheets 41 are separated by the gap 40, and the gap extends along the line of force L formed by the center of the pressure, when the flexible sheets 41 When the rebound energy is generated, due to the separation of the aforementioned gap 40, the point of application of part of the rebound energy is regulated at the positions of the inner edges 411, whereby the rebound energy will be distributed along the trajectory force line L Under the circumstances, the rebound energy can be accurately applied to the center of the pressure, which further enhances the flexible sheets 41 The propulsion effect.

Referring to FIG. 9, it is a second preferred embodiment of the present invention, which is substantially the same as the first embodiment, and also includes the sole 3 and the sole rebound structure 4. The difference is that the flexible sheet 41 on the right side also includes a perforation 42 extending from the top surface to the bottom surface. The perforation 42 is used to reduce the structural strength of one of the flexible sheets 41, so that when the pressure required for the deformation of the flexible portions 416 is smaller, it is easier to flex and deform in the direction of the heel 22.

It should be noted that the number of the perforations 42 is not limited to one, and can also be two as shown in FIG. 10, or three as shown in FIG. 11, which can also reduce the structural strength of one of the flexible sheets 41 , When the pressure required to deform the flexure portions 416 is smaller, it is easier to flex and deform in the direction of the heel 22. Since those with ordinary knowledge in the field can deduce the details of the expansion based on the above description, no further description is given.

In addition, the flexible sheets 41 are not limited to those shown in Figs. 2 to 11, but are arranged in a left and right arrangement. In other variations of the foregoing embodiment, the flexible sheets 41 can also be arranged along the lines shown in Figs. The longitudinal direction X is arranged above and below each other in parallel. Thereby, the flexible sheets 41 can also be released from the ground, because the pressure of stepping disappears, relative to the front edge of the heel 22 or the forefoot 21, the rebound energy is generated to advance the heel 22 and the forefoot. Palm 21. In this way, the energy loss of the feet during running or walking is reduced, and the effect of labor saving is achieved.

Based on the above description, the advantages of the foregoing embodiments can be summarized as follows:

1. The present invention divides the sole rebound structure 4 into two through the gap 40, and can make each flexible piece 41 with a smaller pressure when the pressure required to bend each flexible piece 41 becomes smaller. 41 is easier to flexibly deform, and generates more rebound energy to advance the sole 2, which reduces the energy loss when the sole 2 is exerted, effectively improves the efficiency of labor saving, and makes the sole 2 move more labor-saving.

2. Furthermore, since the gap 40 extends along the trajectory force line L, when the flexible sheets 41 generate rebound energy, the point of action of part of the rebound energy will be regulated at the inner edges 411 The position enables the rebound energy to accurately act on the center of the pressure, and further enhances the propulsion effect of the flexible sheets 41.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to Within the scope of the patent for the present invention.
