Description

[Technical Field]

[0001] The present disclosure relates generally to footwear soles, and more particularly to soles that provide all-directional traction. The present invention relates to an outsole for footwear that includes a pattern that can impart different stiffness characteristics. [Background technology]

[0002] Many conventional shoes or other footwear generally have an upper and a shoe attached to the bottom of the upper. A conventional shoe receives the user's foot before fastening the shoe to the foot. The interior space, i.e., the void or cavity formed by the interior surfaces of the upper and sole The sole is attached to the underside or boundary of the upper and is in contact with the ground. As a result, the sole provides stability and cushioning when the shoe is normally worn. In some examples, the sole may comprise an outsole, a midsole, The outsole can include multiple components such as a shoe insert, a shoe boot insert, and an insole. The midsole provides traction to the ground-engaging surface of the outsole. It can be attached to the upper surface to provide cushioning or additional stability to the sole. For example, the sole may be configured to provide increased stability at one or more desired locations along the sole. Certain foam materials may cause irritation, or the user may be running, walking, or engaging in other physical activities. foam materials that can sometimes reduce the stress or impact energy applied to the foot or leg It may include.

[0003] With respect to athletic shoes, such as soccer cleats, the sole assembly provides durability, wear, and Formed from one or more materials to provide resistance, abrasion resistance, or traction In some cases, the outsole of the athletic shoe may include , may have properties that affect the bending stiffness of the footwear.

[0004] In recent years, the influence of the bending stiffness of the sole on the athletic ability of the wearer has been investigated, and several Studies have shown that shoes with relatively stiff soles reduce metabolic costs during running and / or It has been shown that the material can provide spring-like properties that aid in running propulsion. In some conventional constructions, athletic shoes have a sole that is designed to increase the overall bending stiffness of the sole. However, the saw blade may contain a hardening component that can be embedded within the saw blade. Including additional components within the shoe assembly increases manufacturing complexity and Further research is needed to determine whether specific Restricting foot flexion in this area can negatively impact a user's performance. It has been suggested that there is.

[0005] The anatomy of the foot includes various bones, joints, and movements that are sensitive to the structure and performance of the foot. For example, this sensitivity can be described as proprioception, also known as the "sixth sense," which This includes the perception or awareness of one's own body position and movement. provides flexibility and stiffness as needed, and supports the natural movement of the foot inside the footwear. Designing footwear that improves human proprioception by accommodating bending and flexion That can be advantageous.

[0006] Athletic shoes have also long been known to include means for improving ground contact. It is well known that certain tread configurations can be designed to provide performance advantages. For example, the soles of shoes for court sports such as basketball are designed to provide a quick start, Various tread designs for increased traction to allow for tops and turns Baseball, football, soccer, etc., played on grass or turf. In sports such as , blades, or cleats) to provide the desired traction and It becomes easier to change direction.

[0007] Ground-engaging members for athletic shoes are designed to engage with the surface on which the cleat or shoe is intended to be used. For example, athletic shoes may be designed for hard ground, soft ground, and Constructed for use on artificial turf, street surfaces, or indoor courts (e.g., futsal courts) Hard ground cleats, primarily used on natural grass and outdoor fields, may be used. non-removable cleats or straps designed to provide traction and stability Soft ground cleats are typically used on wet or muddy ground. It has long studs for improved traction and is suitable for a variety of terrains. Metal-tipped studs and / or removable studs for customization to your requirements Street cleats and turf shoes typically include rubber cleats. It has a rubber outsole with protrusions on the outside of the outsole for improved traction. It may contain small rubber studs that protrude from the

[0008] Ground engaging members (e.g., cleats or studs) are often cone-shaped, blade-shaped, , angled, or combinations or variations thereof, each shape providing specific performance benefits. For example, conical studs are known to provide a cylindrical outer surface. Provides omnidirectional traction for ease of movement in all directions Blade-shaped or angle-shaped cleats typically have a specific The ground engaging portion is more suitable for assisting traction and acceleration along the road. The spatial distribution of materials can affect the performance of the outsole. The material configuration can be modified to improve traction in a particular direction, for example, or to improve overall comfort. The data may be optimized for various purposes, such as improving response time.

[0009] In view of the above, athletic shoes often have an aerodynamic design with zones having different bending characteristics. It is desirable to have an outsole. In addition, a tread pattern for improved traction and comfort is also included. There is also a demand for athletic shoes that offer unique designs.

[0035] Before describing the outsole according to the present disclosure in detail, reference is made to the anatomy of a human foot 10 shown in FIG. The foot 10 includes a calcaneus 90, tarsals 92, metatarsals 94, and phalanges 96. 4 to the toes or phalanges 96 at the metatarsal-phalangeal joints 98a-98d (or collectively 98) Connect.

[0036] During a running activity, as the foot 10 pushes off the ground, the tarsal bones 92 and The metatarsals 94 naturally lock together and act as lever arms to propel the leg forward. However, the slight movement between the tarsal bones 92 and metatarsal bones 94 creates some energy. Energy dissipates, thereby creating inefficient thrust.

[0037] The metatarsal-phalangeal joints also play an important role in running, jumping, and cutting activities. For example, during various athletic activities, the peak plantar pressure occurs at the first metatarsal-phalangeal joint 9 It occurs under the big toe joint 8a (also known as the "hallux joint"), and joints 98a-98e collectively flex the toes and The first metatarsal can provide the user with balance and propulsion while walking. The phalangeal joint 98a often serves as a fulcrum around which rotational and pivotal movements of the foot 10 occur. It works like this.

A first set of circular ridges 128 aligned and extending outward therefrom and a second epicenter A second set of circular ridges 13 are concentrically aligned with and extend outward from 134. 2. The first epicenter 130 is located in the toe region 118 and the second epicenter 134 is located in the heel region 122. However, in other embodiments, the first and second airfoils The pin centers 130, 134 may be located in different areas.

[0045] The first epicenter 130 is proximal to the medial surface 124. and distal to the lateral surface 126. The first epicenter 130 is spaced inward from the inner surface 124 of the first epicenter 130. This corresponds generally to the location of the first metatarsal-phalangeal joint 98a (shown in FIG. 1).

[0046] FIG. 8 is a schematic diagram showing a simplified version of the surface pattern 114. 8 is provided to more clearly show the surface pattern 114 of the filter 102. The first set of circular ridges 128, or portions thereof, may be located in the forefoot region 118, the midfoot region 120, and heel region 122, respectively. The ridges belonging to set 128 may extend into any area of ​​outsole 102 . Generally, the ridges in the first set of circular ridges 128 provide omnidirectional traction on the outsole 102. tion and around the first epicenter 130 (or the first metatarsal shown in FIG. 1 - about the interphalangeal joints 98a. Additionally, any of the circular ridges 116 may help grip the surface of the ball. or stain release properties.

[0047] A second set of circular ridges 132, or portions thereof, are located in the midfoot region 120 and heel region 122. However, in some embodiments, the second circular ridge is located at each of the The set 132 may extend further into the toe region 118. The raised portions of the pads 132 can provide omnidirectional traction to the outsole 102, of the footwear 100 around the second epicenter 134 (or around the calcaneus 90 as shown in FIG. 1). Rotational or swiveling movements can be facilitated.

[0048] Each ridge in the first and second sets of circular ridges 128, 132 has a diameter (or radial The diameter of any one ridge is the width of the first or second epicenter. 130, 134. Therefore, the first epicenter The first set of circular ridges 128, which are located relatively close to the first set of circular ridges 130, are located outward. The second epitaxial layer has a smaller diameter (or radial width) than the first epitaxial layer. The ridges of the second set of circular ridges 132 located relatively close to the center 134 are It has a smaller diameter (or radial width) than the outwardly disposed ridges. The laterally disposed ridges surround the inwardly disposed ridges. Referring to FIG. The first set of circular ridges 128 includes an inner ridge 128a and an outer ridge 128b. The inner ridge 128a is disposed inwardly relative to the outer ridge 128b. The diameter of the outer ridge 128a is smaller than the diameter of the inner ridge 128b. Enclose 28a.

[0049] Continuing to look at FIG. 8, the ridges of the first set of circular ridges 128 are spaced a predetermined distance apart. As shown here, the first set of circular ridges 128 The spacing between adjacent ridges is generally equidistant. The outer ridges of the first set of circular ridges 128 in the oval ridges 8 are located near the first epicenter 130. The first epicenter 130 is spaced approximately 1.33 times farther away than the adjacent ridges. The larger spacing of the first set of circular ridges 128 provides more flexibility. This may be desirable in areas of the footwear 100 that include the phalanges 96 (shown in FIG. 1). This allows them to move and flex more freely.

[0050] The ridges in the second set of circular ridges 132 may also be spaced apart a predetermined distance. a second set of circular ridges 132 proximal to a second epicenter 134 of region 122; a second set of circular ridges 13 distal to a second epicenter 134 in the metatarsal region 120; The ridges are spaced about 1.67 times farther apart than the ridges in the heel region 122. The stiffness of the outsole 102 in the midfoot region 120 is Additionally or alternatively, the ridges of the first set of circular ridges 128 The spacing between the first and second set of circular ridges 132 in the midfoot region 120 is approximately the same. It's okay to have one.

[0051] As shown in FIGS. 6A and 6B, each of the plurality of circular protrusions 116 is formed on the upper surface 11 0, a pair of opposing side walls 138, a distal edge 140, and the base 136. Extending perpendicularly from any point along the ridge 116 to its farthest point along the distal edge 140 In some embodiments, the height 142 is defined as the linear distance between the The opposing side walls 138 may have a width in the range of about 0.1 mm to about 7.0 mm. The circular ridges 116 extend from the base 136 so that each ridge has a substantially triangular cross section. It tapers inwardly towards the distal edge 140. The distal edge 140 also tapers inwardly towards the distal edge 140 as shown. However, in other embodiments, the ridges may have other cross-sectional shapes and The slits may be formed to have different sizes.

[0052] In some cases, the circular ridges within the plurality of circular ridges 116 have different heights 142. The change in height 142 along the circular ridge 116 may include at least one high portion 144 (shown in FIG. 6B) and at least one lower portion 146 (shown in FIG. 6A) ) can define a distal edge 140 that varies in an undulating manner between . In this case, the tall portion 144 may have a height 142 in the range of about 5 mm to about 7 mm. In some embodiments, the lower portion 146 has a height 142 ranging from about 0 mm to about 3 mm. It is possible.

[0053] The circular ridges 116 projecting to different heights 142 provide different stiffness to the outsole 102. For example, a circular ridge having a height 142 of 7 mm or thereabouts can be provided. 116 increases the stiffness of the outsole 102, but the height 142 is 0 mm or near The circular ridges 116 reduce the stiffness of the outsole 102. Additionally, the wavy distal edge In an embodiment having a circular ridge 116 with 140, the stiffness of the outsole 102 is In different areas of the outsole 102, circular ridges 116 (hereinafter 142) (described below) to be relatively large or small.
