Description

An easily bendable flexible non-slip sole and its footwear products

technical field

The utility model relates to the field of footwear products, in particular to an easily bendable flexible anti-skid sole and footwear products.

Background technique

Footwear, especially sports shoes, in order to be comfortable to wear, run and jump freely and ensure foot safety, the soles are required to have flexible bendability, which can provide good bending performance in all directions of the soles, and Easy to rebound, not deformed. Good bending performance can not only make walking or exercising more freely and improve sports performance, but also reduce the reaction force caused by the bending of the sole and protect the safety of the feet. In the actual use of the sole, the sole will flex continuously. During the repeated flexing process, the repeated tensile stress on the sole surface will cause cracks and crack growth in the sole, and finally cause the sole to break. Frequent flexing of the sole is one of the main causes of product damage.

In order to improve the bending flexibility of the existing soles, various grooves are arranged on the soles by designing molds, inlays and other methods. This method is not only cumbersome, the cost of mold opening is high, and it is also difficult to demould for complex shading. It is difficult, and defective products are prone to occur. At the same time, the groove obtained by the mold has a certain width, and it is easy to get stuck in foreign objects when wearing.

Utility model content

In order to solve the above technical problems, the utility model intends to provide a flexible anti-skid sole that is easy to bend, while providing a sole structure with high flexibility in all directions and each part, and at the same time ensuring that it will not be broken and cracked. The anti-skid performance is further improved, and a sole structure with excellent comprehensive performance is obtained.

An easily bendable and flexible anti-skid sole includes a sole body, and the bottom surface of the sole body is provided with a transverse cutting groove and a longitudinal cutting groove.

The transverse direction refers to the width direction of the foot or shoe, and the longitudinal direction refers to the length direction of the foot or shoe.

The above-mentioned transverse and longitudinal cutting grooves are directly cut with a knife on the bottom surface of the molded shoe sole, and the formed cutting openings are closed when not in use and open when subjected to bending force in use.

The transverse cutting groove includes a first transverse cutting groove and a second transverse cutting groove, the first transverse cutting groove is provided in the forefoot area of the sole, and the second transverse cutting groove is provided in the midfoot area and heel of the sole area.

The longitudinal cutting groove includes a first longitudinal cutting groove and a second longitudinal cutting groove, the first longitudinal cutting groove is arranged to extend from the forefoot area to the heel area, and the second longitudinal cutting groove is arranged near the inner side of the sole body , The sole area where the sole part is wider than the heel part and extends only in the forefoot area.

The transverse cutting grooves extend laterally, intersect with the longitudinal cutting grooves, and terminate at the two outermost longitudinal cutting grooves, thereby forming a closed quadrilateral dividing block on the bottom surface of the sole body. The longitudinal cut grooves extend from the forefoot area to the heel area, but not to the toe and heel edges.

Further, the transverse cutting grooves are arranged in an approximately parallel manner, and the cutting direction thereof is parallel to the bending axial direction of the foot when walking, the longitudinal cutting grooves are arranged in an approximately parallel manner, and the bottom surface of the sole body is at least provided with One first transverse cutting groove, at least one second transverse cutting groove, at least one first longitudinal cutting groove and at least one second longitudinal cutting groove. Preferably, the bottom surface of the sole body is provided with three first transverse cutting grooves, three second transverse cutting grooves, three first longitudinal cutting grooves, and one second longitudinal cutting groove.

Further, the bottom surface of the sole body also includes a plurality of discontinuous small block-shaped raised sole elements. Preferably, the shape of the raised sole element is an irregular polygon, and the plurality of discontinuous small block-shaped raised sole elements are irregular polygons of different shapes.

The side of the sole is provided with a vertical shallow groove inclined from the rear to the front. Preferably, the shallow grooves are provided in the midfoot area and the heel area of the sole body.

Through the above technical solutions, the beneficial effects of the present utility model are:

1. The cutting-type sole groove is adopted. Compared with traditional mold forming and inlay methods, the process is simple and the cost is reduced; at the same time, it is more flexible and easy to bend, and the shading is usually closed, and it is not easy to get stuck in foreign objects. Reduced sole wear. According to the use characteristics of each part of the sole, different numbers and arrangements of cutting grooves are set to maximize the multi-directional flexibility of each part of the sole.

2. When the sole is in use, most of the bending occurs in the lateral direction, so the lateral cutting groove is prone to damage to both sides due to repeated bending, and may even be partially broken, which affects the performance of the sole and the appearance of the shoe. . The transverse cutting groove of the utility model extends laterally, intersects with the longitudinal cutting groove, and ends at the two outermost longitudinal cutting grooves, thereby forming a closed quadrilateral dividing block on the bottom surface of the sole main body. This arrangement makes the transverse cutting groove limited by the longitudinal cutting groove, cuts off the tearing path of the transverse cutting groove to both sides, and avoids tearing and breaking. Longitudinal cuts do not extend to the edge of the toe and heel to avoid continuous cracking of the cut ends.

3. The sole is provided with a plurality of discontinuous small block-shaped raised sole elements, preferably irregular polygons. These discontinuous small blocks provide the sole with greater friction, and when stepping on, these small blocks are squeezed. Together, the air in the narrow gap in the middle is squeezed out, which produces a certain grip on the ground. On the road with water, it can also play the role of draining the water between the gaps, so it has the function of gripping and anti-slip. In the same way, the intersection of the horizontal and vertical cutting grooves forms a quadrilateral dividing block, which can also play the same role.

4. A vertical shallow groove is arranged on the side of the sole and inclined from the back to the front, that is, in the same direction as the bending direction of the sole, which improves the lateral bending performance.
