JP7104113B2 - Golf shoes with outsole with crossing track including traction member - Google Patents

Description

The present invention relates to shoes in general, and more specifically to golf shoes having good flexibility, stability, and traction. The midsole is preferably made of two foam materials with different properties. The outsole contains multiple traction members and has a geometric structure that provides high traction and ground contact.

Today, both professional and amateur golfers use specially designed golf shoes. Typically, a golf shoe includes an upper and outsole portion, along with a midsole that connects the upper to the outsole. The upper is a traditional shape for inserting the user's foot and covers and protects the foot of the shoe. The upper is designed to fit the contours of the foot comfortably. The midsole is relatively lightweight and provides cushioning for the shoe. The outsole is designed to provide golfer with stability and traction. The bottom of the outsole may include spikes or cleats designed to engage the ground through contact with the ground and penetration of the ground. These factors help golfers improve stability and traction as they play around the course on foot.

Often, the terms "spike" and "cleat" are used interchangeably in the golf industry. Some golfers prefer the term "spike" because cleats are often associated with other sports such as baseball, soccer, and soccer. Other golfers prefer to use the term "cleat" because spikes are more commonly associated with non-turf sports such as trucking and cycling. In the following description, the term "spike" will be used for convenience. Golf shoe spikes can be made of metal or plastic material. However, one problem with metal spikes is that they usually have elongated, pointed edges that extend downwards, which can pierce the surface of the putting green and puncture it, causing other damage. These metal spikes can also damage other grounds on the golf course, such as clubhouse carpets and flooring. Today, most golf courses require golfers to use non-metal spikes. Plastic spikes usually have a rounded base with a central stud on one side. On the other side of the rounded base is a radial arm with traction protrusions for contact with the ground. As further described below, threads are provided around the spike studs for insertion into the threaded receptacles on the shoe outsole. These plastic spikes can be easily fixed and later removed from the lock receptacle on the outsole, which tends to reduce damage to the green and clubhouse floor surfaces.

If the spikes are on golf shoes, they are preferably removably secured to the receptacle (socket) of the outsole. The receptacle can be placed in a molded pod attached to the outsole. Molded pods help provide the shoe with additional stability and balance. The spikes can be easily inserted and removed from the receptacle. Usually, the spike can be fixed by inserting it into the receptacle and twisting it slightly clockwise. The spike can be removed from the receptacle by twisting it slightly counterclockwise.

In recent years, "spikeless" or "cleatless" shoes have become more common. The outsole of these shoes contains rubber or plastic traction, but no spikes or cleats. These traction members project from the bottom surface of the outsole and come into contact with the ground.

When golfers swing the club to transfer weight, their feet absorb tremendous force. For example, when a right-handed golfer first puts his foot before starting the club swing motion (that is, when addressing the ball), the weight is evenly distributed between the front and back feet. To. When the golfer begins the backswing, the weight mainly shifts to the rear foot. At the beginning of the downswing, there is considerable pressure on the hind legs. Therefore, the rear foot can be called the driving foot, and the front foot can be called the stable foot. As the golfer continues to swing and drive the ball, its weight moves from the driving foot to the forward (stable) foot. During the swing motion, there is a pivot movement of the rear foot and the front foot, but the movement of this pivot needs to be controlled. When making a shot, it is important that the foot does not move or slip substantially. Foot traction is important in a golf shot cycle. It is important that the shoe provides excellent stability. Golfers need a stable platform so that they can maintain balance while swinging. Golf shoe manufacturers have considered various ways to improve the stability of golf shoes. For example, manufacturers are considering placing traction members and spikes at various locations throughout the outsole.

Golf shoe manufacturers have developed shoes with different spikes to provide golfers with traction and stability. For example, US Pat. No. 6,161,315 (Dalton) discloses an outsole with a forefoot section, a shank section and a heel section. On the outer surface, stability ridges are placed along the perimeter of the forefoot and heel. According to the '315 patent, this outer ridge provides torsional traction and stability without adversely affecting the golfer's swing. The ridge can include one or more spikes.

US Pat. No. 8,082,686 (Campbell et al.) Discloses cleats shoes that provide cushioning support and lateral stability. Shoes include the bottom and top. The lower part can include the primary midsole, cushioning element, and outsole. Good the cleats were tied to the outsole. At least one cushion may be placed between the primary midsole and the outsole.

US Pat. No. 8,677,657 (Bacon et al.) Discloses golf shoes having an outsole with a plurality of pod portions molded on the bottom surface thereof. Each pod section contains a receptacle to hold removable cleats (spike). Preferably, there are eight separate pod sections. The pod section has a flared perimeter that extends beyond the normal contours of the outsole. According to the '657 patent, these pods, with spikes and an outer surface, are flared from the normal contours of the outsole to improve stability and support during a golf swing.

US Pat. No. 9,609,915 (Rushbook et al.) Discloses an outsole with spikes and flexzones that allow relative movement between regions on the bottom of the outsole separated by flexzones. According to the '915 patent, such relative movements, along with spikes, help provide golfers with traction and stability.

However, one drawback of some traditional golf shoes is that while these shoes may help provide golfers with good stability and traction, they can compromise the flexibility of the shoe. .. Some traditional golf shoes are relatively stiff. It provides a rigid platform, but does not provide the flexibility that golfers need. As further explained below, when a golfer swings a club and transfers his or her weight to the foot, the foot exerts a great deal of force. When a golfer makes a swing, the shoe needs to provide the golfer with a stable platform, but the foot must also be able to bend to some extent. Bending of the shoes is also important when the golfer is walking on the course, crouching down to align the putts, and during other golf movements.

Therefore, there is a need for golf shoes that can provide a high level of stability and traction, as well as high flexibility. When weight is transferred during a golf shot, the shoe must hold and support the inside and outside of the golfer's foot. The shoe provides stability and traction so it is non-slip, which allows the golfer to maintain balance when swinging the club. At the same time, shoes also need to be very flexible. A golfer in shoes needs to be able to play the course while walking and comfortably participate in other golf activities. The present invention provides the golfer with high stability, traction and flexibility, and provides a new golf shoe structure with other advantageous properties and characteristics.

Detailed description of the invention

In the figure, similar reference numbers are used to indicate similar elements. Refer to the figure below. Specifically, referring to FIG. 1, an embodiment of the golf shoe (10) of the present invention is shown. The shoe (10) includes a midsole (14) that connects the upper (12) to the outsole (16), in addition to the upper portion (12) and the outsole portion (16). The midsole (14) is coupled to the upper (12) and outsole (16) as described in detail below. The appearance shown in the figure is that of the left and right shoes, and it is understood that the left and right shoes and the components of each shoe are mirror images of each other. Also, it should be understood that shoes can be manufactured in various sizes, and therefore the size of the components of the shoe can be adjusted according to the size of the shoe.

The upper (12) has a traditional shape and is made from standard upper materials such as natural leather, synthetic leather, non-woven material, natural fiber, and synthetic fiber. For example, breathable mesh and synthetic fabrics made from nylon, polyester, polyolefin, polyurethane, rubber, and combinations thereof can be used. The materials used in the construction of the upper are selected based on desirable properties such as breathability, durability, flexibility and comfort. In one example, the upper (12) is made of a soft, breathable leather material that is waterproof. The upper material is sewn or joined to form the upper structure using conventional manufacturing methods. With reference to FIG. 1, the upper (12) generally includes an instep region (17) with an opening (20) for inserting the foot. The upper (12) preferably includes a softly molded effervescent heel collar (18) to enhance comfort and compatibility. An optional gil strip (31) is wrapped around the heel collar. The upper contains a toe skin (19) to cover the anterior part of the foot. The instep region includes a tongue member (22) and a power harness (21), which power harness (21) covers the upper quarter section (23) and is connected to the instep (29) in the heel region. The power harness (21) helps with medical control and support of the foot. Typically, shoelaces (24) are used to tighten the shoe around the contour of the foot. However, other tightening systems can also be used, such as a metal cable (race) tightening assembly that includes a dial, spool, housing, and a locking mechanism to lock the cable in place. Such race tightening assemblies are available from Boa Technology, Inc. of Denver, Colorado. The above-mentioned upper (12) shown in FIG. 1 is only an example of an upper design that can be used for the shoe structure of the present invention, and other upper designs can also be used without departing from the spirit and scope of the present invention. I want you to understand.

The midsole (14) is relatively lightweight and provides cushioning to the shoe. The midsole (14) can be made from a midsole material such as, for example, an ethylene vinyl acetate copolymer (EVA) or a polyurethane foam composition. In one preferred embodiment, the midsole (14) is constructed using two different foam materials, as described below.

With reference to FIGS. 2-6, the midsole (14) generally includes two regions: (a) upper (inner) region (28) and (b) lower (external) region (30). In one preferred embodiment, the upper region (28) is made of a relatively soft and flexible material. For example, the upper region (28) can be made from a relatively soft first EVA foaming composition having a hardness in the range of about 40 to about 75 Shore C. In one specific example, the relatively soft first EVA effervescent composition has a Shore C hardness in the range of about 50 to about 70. In one preferred embodiment, the relatively soft first EVA effervescent composition has a hardness in the range of about 55 to about 60 Shore C. On the other hand, the lower region (30) is preferably made from a relatively hard material such as a second EVA foaming composition. In one embodiment, EVA and styrene block copolymer rubber (such as "SI", "SIS", "SB", "SBS", "SIBS", "SEBS", "SEPS", etc. "S". Can be used to form a relatively hard second EVA foam composition using a blend of styrene, "I" for isobutylene, "E" for ethylene, "P" for propylene, and "B" for butadiene). can. The hardness of the lower region (30) is preferably higher than the hardness of the upper region (28). For example, the lower region (30) may be made from a relatively hard second EVA foaming composition having a hardness in the range of about 45 to about 80 Shore C. In one specific example, the relatively hard second EVA effervescent composition has a Shore C hardness in the range of about 50 to about 75. In one preferred embodiment, the relatively hard second EVA foam composition has a hardness in the range of about 65 to about 70 Shore C. For example, the hardness of the effervescent lower region (30) can be at least 5% greater than the hardness of the effervescent upper region (28). In some examples, the hardness of the effervescent lower region (30) may be at least 10% or 15% greater, and in other examples it may be at least 20% or 25% greater. The densities of the first effervescent composition and the second effervescent composition are also preferably different. For example, the density of the relatively hard second EVA foaming composition used to form the lower region (30) is preferably the relatively soft second used to form the upper region (28). It is higher than the density of the EVA effervescent composition of 1.

As discussed earlier, EVA foaming compositions are preferably used to form the midsole. Various foaming additives and catalysts are used in the production of EVA foams. For example, EVA foaming compositions usually include polyethylene. The EVA foaming composition has various properties that are particularly suitable for the construction of midsole, which provides excellent cushioning and shock absorption; high water and moisture resistance; and long-term durability. include.

With reference to FIG. 7, the upper and lower regions (28, 30) of the midsole (14) are shown in exploded views. In one manufacturing process, the midsole (14) is molded as a separate part and then stitched, glued, or other suitable means using standard techniques known in the art. Can be joined to the top surface (33) of the outsole (16). For example, the midsole (14) can be hot pressed and adhered to the top surface (33) of the outsole (16). The midsole (14) can be molded using a "two-shot" molding method.

With reference to the outsole (16), this portion is primarily designed to provide shoe support and traction. The bottom surface (27) of the outsole (16) includes a plurality of traction members commonly shown by (25) of FIG. The traction member (25) serves to provide traction between the shoe and the various surfaces of the golf course. The traction member (25) can be made of any suitable material such as rubber, plastic, and combinations thereof. Thermoplastics such as nylon, polyester, polyolefin and polyurethane can be used. In one preferred embodiment, the traction member is made of a relatively hard thermoplastic polyurethane composition. Different polyamide compositions, including polyamide copolymers and aramids, can also be used to form traction members. For example, Pebax ™ elastomer (available from Arkema), which is a block copolymer of a hard polyamide block and a soft polyether block, can be used. Suitable rubber materials include polybutadiene, polyisoprene, ethylene propylene rubber (“EPR”), ethylene propylene diene (“EPDM”) rubber, styrene butadiene rubber, styrene block copolymer rubber (eg SI”, “SIS”. , "SB", "SBS", "SIBS", "SEBS", "SEPS", etc. Here, "S" is styrene, "I" is isobutylene, "E" is ethylene, and "P" is propylene. , "B" is butadiene), polyalkenamers, butyl rubber, nitrile rubber, and blends of two or more thereof. The structures and shapes of the different traction members (25) and outsole (16) of the present invention are described in more detail below.

In general, the anatomy of the foot can be divided into three bone regions. The posterior foot region usually includes the ankle (talus) and heel (calcaneus) bones. The central foot region includes the rectangular bones, cuneiform bones, and scaphoid bones that form the longitudinal arch of the foot. The anterior foot region includes the metatarsal bones and toes. As shown in FIG. 1, the outsole (16) has an upper surface (not shown) and a lower surface (27). The midsole (14) is joined to the upper surface of the outsole (16). The upper (12) is attached to the midsole (14).

With reference to FIG. 2, the outsole (16) generally has an anterior foot area (40) for supporting the anterior foot area; a central foot area (42) for supporting the central foot including the arch area. ); Includes the posterior region (44) to support the posterior foot including the heel area. Generally, the anterior foot region (40) includes the toes and the portion of the outsole that corresponds to the joint that connects the metatarsal bones to the phalanges. The midfoot region (42) generally includes a portion of the outsole that corresponds to the arch area of the foot. The posterior foot region (44) generally includes a portion of the outsole that corresponds to the posterior portion of the foot, including the calcaneus.

The outsole (16) also includes the outer (lateral side) (46) and the inner (medial side) (48). The lateral (46) and medial (48) extend through each foot region (40, 42, and 44) and correspond to the opposite side of the outsole. The lateral or lateral edge (46) of the outsole is the side corresponding to the lateral region of the wearer's foot. The lateral edge (46) is generally the farthest side of the wearer's foot from the wearer's other feet (ie, it is the side closer to the fifth toe [small toes]). The medial or medial edge (48) of the outsole is the side corresponding to the medial area of the wearer's foot. The medial edge (48) is generally the side of the wearer's foot that is closest to the wearer's other foot (ie, the side closer to the hallux [thumb]). More specifically, the outside and inside extend from the front end (52) to the rear end (54) of the outsole, around or around the outsole (16). The front end (52) is the part of the outsole corresponding to the toe area and the rear end (54) is the part corresponding to the heel area. The areas, sides (sides, sides), and areas of the outsole described above are not intended to distinguish the exact area of the outsole. Rather, these areas, sides, and areas are intended to represent the general area of the outsole. The upper (12) and midsole (14) also have such areas, sides and areas. Each area, side, and area may also include anterior and posterior parts.

[Forefoot area]
Returning to FIG. 1, the traction member (25) protrudes from the bottom surface (27) of the outsole (16) in the forefoot (40) region and is in contact with the ground. The traction member (25) helps to provide the golfer with good stability and traction when the golfer is walking and playing on the course as described above. The protruding traction member (25) extends along the length of the outsole (16) and is found in the forefoot, midfoot, and hindfoot regions (40, 42, and 44).

The outsole (16) can include a wide variety of traction members (25) to maximize traction and grip on various golf course surfaces and add to that surface for the amount of traction provided. There is little damage. The traction member (25) includes, but is not limited to, for example, annular, rectangular, triangular, square, spherical, elliptical, star, diamond, pyramid, arrow, conical, blade, and rod shapes. , Can have many different shapes. In addition, the height and area of various traction members (25) can be adjusted as needed. In one preferred embodiment, the golf shoe of the present invention has five different traction members (25) extending along the length of the outsole (16), which traction members are described in more detail below. do.

The anterior, central, and posterior foot areas (40, 42, and 44) of the golf shoe (10) are important to provide stability and comfort to the foot, in addition to traction. .. For example, on many golf courses, golfers can choose to drive an electric cart or walk the course. Some golfers prefer to walk the entire course. Even golfers who prefer to drive a cart walk a considerable distance during a round of play. Depending on the length of the course, the speed of play, and other factors, golfers may walk several miles in a round. Therefore, golf shoes need to be comfortable to wear and allow golfers to walk naturally and freely. That is, shoes need to support the foot, but they also need flexibility. Golfers need to be able to perform golf-specific actions such as dealing with the ball, swinging, walking comfortably on the course, and crouching to line up putts. There are two important directions of foot movement that must be considered. That is, (1) dorsiflexion and (2) sole flexion. In general, dorsiflexion is the action of lifting the foot (60) upward toward the shin. That is, the foot (60) is bent dorsally or upward. The muscles and tendons in the front of the foot and leg that pass through the ankle joint are used to move the foot in the dorsiflexion direction. Generally, the foot (60) moves upward in the range of about 10 degrees to about 30 degrees. On the other hand, sole flexion is an action of moving the foot (60) downward toward the ground. The muscles and tendons behind and inside the foot and legs that pass through the ankle joints are used to move the foot in the direction of plantar flexion. Generally, the foot (60) moves upward in the range of about 20 degrees to about 50 degrees.

With reference to FIGS. 8A-8C, a normal walk cycle is schematically shown. Typically, when a person begins to walk naturally, the outer part of the heel first hits the ground and the foot (60) is slightly supinated. FIG. 8A shows one version (right foot) of the golf shoe (10) of the present invention in which the heel portion of the outsole (16) first hits the ground when the golfer begins walking. When a person transfers weight to the medial portion of the foot (60), the arch flattens and the foot is pushed downwards. The foot (60) also begins to roll slightly inward and reaches the inward position. In some cases, the foot (60) may roll excessively inward, which is a type of gait called excessive pronation. In another example, the foot (60) does not rotate sufficiently inward, which is called lack of pronational movement. FIG. 8B shows the posterior and anterior portions of the outsole (16) in contact with the ground. Normal foot pressure is applied downwards and the foot 60) begins to move to the normal pronational position, which helps absorb the impact. After the foot (60) reaches this neutral position (FIG. 8B), the person continues walking with the thumb of the foot detached (FIG. 8C). At this point, the foot (60) also rotates slightly outward. In FIG. 8C, the anterior portion of the outsole (16) is shown to be in contact with the ground as a person pushes his foot away and begins the next step. The golf shoe (10) of the present invention has good stability, yet also provides good forefoot flexibility so that the golfer can easily and comfortably perform his or her natural walking behavior.

[Central foot area]
The midsole (14) of the shoe (10) of the present invention has many advantages and advantages, such as providing cushioning and support. When walking or playing golf, the forces acting on the foot (60) and the various parts of the shoe (10) are diverse. For example, downward and upward forces can act on the midsole (14) during a golf swing. The midsole (14) of the present invention can provide consistent comfort and support when such forces are applied.

Like the forefoot region (40), the central foot region (42) also includes a traction member (25) that projects from the bottom surface (27) of the outsole (16) to contact the ground. The midfoot region (42) includes a traction member (25) that provides high surface area contact with the ground and helps prevent the outsole from slipping or slipping. In one preferred embodiment, the golf shoe (10) of the present invention has five extending along the forefoot, midfoot, and hindfoot regions (40, 42, and 44) of the outsole (16). It has different traction members (25), and these traction members will be described in more detail below. The midfoot region (42) also contains a footbridge or shank that helps provide high stability and support. This is also explained in detail below.

As shown in FIG. 9, the golf shoe (10) of the present invention has good torsional stability. That is, the midsole (14) and outsole (16) help provide the shoe (10) with high mechanical strength and structural integrity, and the midfoot region (42) along the longitudinal axis A. Does not allow excessive twisting or rotation of. .. The shoe (10) helps provide the golfer with a stable platform, which is especially important when the golfer swings and hits the ball.

During golf, golfers often need to place their feet on non-horizontal surfaces such as rocks, rods, and other debris-studded surfaces. This rugged terrain creates a strong force on the foot and can create an unstable platform for golfers. This instability is a particularly difficult problem when the golfer needs to deal with the ball and make a shot. In addition, these continuous stresses can cause pain in the ligaments, tendons, and muscles of the foot, resulting in sprains and tears. The golf shoe (10) of the present invention helps to address these problems by improving the stability and support of the foot. The shoe (10) helps provide a stable platform for the golfer to tackle and swing the ball. The shoe (10) provides this stable platform by resisting bending in the flexion direction of the sole. At the same time, the shoe (10) has good flexibility of the front foot and can be bent in the dorsal flexion direction. Therefore, the shoes of the present invention provide a stable platform without sacrificing flexibility. Therefore, a golfer can perform his swing on all types of golf course terrain, including surfaces with rough and non-flat surfaces, as described in more detail below. At the same time, the shoes are highly flexible in the forefoot, providing full support for the golfer to walk comfortably in a natural way.

With reference to FIGS. 10A-10E, the high stability and traction of the golf shoe (10) of the present invention is shown in more detail in the schematic. In FIG. 10A, it is shown that a golfer wears the golf shoe (10) of the present invention on a terrain having a flat surface, such as a golf course fairway. Generally, the fairway is an area of very short mowed grass on a golf course that runs between the tee box and the putting green. The shoes of the present invention provide golfers with high stability and support on fairways and other substantially horizontal surfaces. Next, in FIGS. 10B and 10C, it is shown that a golfer wears a conventional golf shoe (65) on a terrain having a non-flat surface such as a rough golf course. Rough is generally a high grass and thick area of a golf course. Uncut high grass is outside the fairway boundaries. Rough often contains wild plants that grow naturally. These conventional shoes (65) tend not to provide high stability and support on roughs with their substantially uneven surface. Rather, as shown in more detail in FIG. 10C, these conventional shoes (65) tend to bend in a concave shape. This concave bending flexion is problematic as it creates vertical hindfoot movement during loading and unloading of the golf swing. Next, referring to FIGS. 10D and 10E, the golfer is shown wearing the golf shoe (10) of the present invention on the same non-horizontal rough as shown in FIGS. 10A and 10B. However, in this example, the golf shoe (10) of the present invention provides high stability and support on this substantially non-horizontal surface. As detailed in FIG. 10E, there is no concave bending of the shoe (10) when the golfer is standing on this uneven and rugged terrain. This is in contrast to the concave flexion that tends to occur in conventional shoes (65) as shown in FIG. 10C. Contrary to such conventional shoes (65), the golf shoes (10) of the present invention provide the golfer with a rigid and stable platform. Golf shoes (10) provide firm support for the foot. The unique construction of these shoes (10) allows the golfer to swing with minimal or no movement of the hind foot during loading and unloading of the swing.

[Hind foot area]
Like the forefoot and midfoot areas (40), (42), the hindfoot area (44) also projects from the bottom surface (27) of the outsole (16) and comes into contact with the ground. (25) is included. The hindfoot "region (44) is relatively large. This relatively wide width further helps to provide good stability to the shoe (10), especially in the heel area. The hindfoot region (44) includes a traction member (25) that provides high surface area contact with the ground and helps prevent the outsole from slipping or slipping. Maximum contact by the traction member (25) is maintained in the posterior foot region (44) and the anterior foot (40) and central foot (42) regions, as described above. The various traction members (25) provide golf-specific traction. That is, these traction members control the lateral traction of the anterior, central, and posterior feet, causing the foot to shift or slip as the golfer walks or plays the course. prevent.

[Towing member]
With reference to FIG. 11, one preferred embodiment of a set of traction members (25) on the outsole (16) is shown in more detail. A first set of traction members is attached to track A, which tracks from the periphery (50) of the medial (48) of the forefoot (40) through the central foot (42) region. It extends to the periphery (50) of the lateral (46) of the hindfoot region (44). A second set of traction members is attached to track B, which tracks posterior from the periphery (50) of the outer (46) of the anterior foot (40) through the central foot (42) region. It extends to the periphery (50) of the medial (48) of the foot region (44).

The first set of traction members disposed on the track A can project outward from a plurality of first traction member bases fixed to the track A. A second set of traction members disposed on the track B can project outward from a plurality of first traction member bases fixed to the track B. The traction member can have various shapes and dimensions, for example, the traction member (70, 72, 74, 76, and 78) can be used as described in more detail below. The traction members and their support base (79) are preferably made of a relatively hard material such as a thermoplastic polyurethane or polyamide composition. Each traction member support base (79) can be secured to tracks A and B by stitching, glue, or any other suitable fixing means. The traction members and their respective bases have various shapes such as, for example, ring, rectangle, triangle, square, sphere, ellipse, star, rhombus, pyramid, arrow, cone, blade, and rod. Can have. The towing member of the truck A and the towing member of the truck B may have the same shape or different shapes. In one preferred embodiment, at least a portion of the traction member of truck A and at least a portion of the traction member of truck B have a conical shape. Tracks A and B are preferably formed from the materials used to make the midsole, such as the EVA or polyurethane foaming compositions described above.

Thus, tracks A and B intersect each other in the central region of the foot (42). When tracks A and B intersect each other to form an X-shaped pattern, geometry similar to an infinite (∞) mathematical symbol is provided to the outsole (16). Tracks A and B generally have a thickness of about 2 to about 6 mm. The thickness of the track varies along the contour of the outsole (16) and may vary from the anterior foot to the central foot, the posterior foot region (40, 42, and 44).

Tracks A and B form an X-shaped pattern in the central foot region (42). This X-shaped structure and infinite (∞) shape help increase the bending rigidity of the shank (foot bridge) (66) of the shoe outsole (16). This precise geometry also helps to provide the shoe (10) with excellent torsional stability. This infinite (∞) shape and X-shaped structure (66) of the central foot region provide the shoe (10) with high mechanical strength and structural integrity and do not twist or rotate the shoe excessively. To do so. The X-shaped foot bridge (66) forms a bridge between the anterior and posterior feet (40, 44) and serves to support the central foot (42). Also, in a preferred embodiment, the central foot stability traction components (83, 85) are arranged on the outer (46) and inner (48) peripheral sides of the central foot region (42), respectively, and the foot. It is placed adjacent to the bridge (66). Central foot stability traction components (83, 85) are not located on tracks A and B. Rather, these stability traction components (83, 85) are located on the outsole between trucks A and B. The traction member (87) of the third set projects outward from the first traction component (83), and the traction member (89) of the fourth set projects outward from the second traction component (85). .. These stability traction components (83, 85) and their respective protruding traction members (87, 89) further serve to provide torsional stability. These stability traction components (83, 85) and traction members (87, 89) help impart rigidity to the shoe without sacrificing the flexibility of the shoe's forefoot.

The logo (81) may be placed in the center of the X-shaped foot bridge (66). One preferred material for forming the visible logo (81) is thermoplastic polyurethane. The logo (81) may be covered and protected by a clear polyurethane film. The reinforced shank (footbridge) (66) helps to provide rigidity and structural support to the outsole. The outsole (16), in turn, improves stability and balance when the golfer walks or plays on the course due to its high mechanical strength properties.

As mentioned above, the traction member on the outsole (16) may have many different shapes, such as, but not limited to, annular, rectangular, triangular, square, spherical, etc. Includes oval, star, diamond, pyramid, arrow, cone, blade-like shapes, and rod shapes. In addition, the height and area of the traction member vary. In the examples of the outsole shown in FIG. 2, these traction members include a type 1 traction member (70) having a conical structure that can be referred to as a "medium dimensional cone". The type 2 traction member (72) also has a conical structure and can be referred to as a "small dimensional conical". The type 3 traction member (74) has a herringbone structure and can be referred to as a "herringbone". The type 4 traction member (76) is conical and can be referred to as a "pivot cone". The type 5 traction member (78) also has a conical structure and can be referred to as a "locking cone". The traction members (70, 72, 74, 76, and 78) and their support bases (79) are preferably made of a relatively hard material such as thermoplastic polyurethane. Also, as shown in FIG. 11, the golf shoe includes a thermoplastic polyurethane bridge (80) that connects the traction member base (79). The outsole (16) can also include a stable ridge (82) in the central region. These stable bumps (82) are not located on tracks A and B. Rather, they are placed between tracks A and B. The shoe outsole (16) of the present invention has more traction members (25), in contrast to many conventional golf shoes, and this large amount of traction members has high traction and good traction. Helps to provide ground contact. Further, as discussed above, the outsole (16) has a larger heel area than many conventional golf shoes, and this function provides high stability.

In addition, as previously discussed and shown in FIGS. 3-7, the lower region (30) of the midsole (14) is preferably a relatively hard material such as a second foamable EVA composition with a high durometer. Made of. This lower region (30) of the midsole (14) forms the sidewalls of the midsole (14), and these stiff and strong sidewalls are inside the golfer's foot when transferring weight when making a golf shot. Helps hold and support the swell and the outer swell. This material build-up in the lower region (30) also helps support the central foot region (42) where the X-shaped footbridge (66) structure is located.

The resulting shoe (10) has the optimum combination of structural stiffness and flexibility. A golfer wearing shoes can walk comfortably and play the course. Golfers do not have to spend undue time and energy adjusting their shoes, which can occur with some traditional shoes. Trivial work on this shoe can lead to golfer fatigue and adversely affect competitive performance on the golf course. Rather, the golf shoes (10) of the present invention can be worn freely and naturally. The shoe (10) is highly flexible in the forefoot, yet does not sacrifice stability, traction, and other important properties as described above. The unique shape and construction of the outsole (16), including the upper (12), midsole (14), and traction member (25), provides the golfer with shoes with many beneficial properties.

The shoe structure described above generally includes a) upper (12); b) outsole with five different traction members (16); c) midsole connecting the upper (12) and outsole (16). 14) The midsole has an i) upper region formed from the first material and ii) a lower region formed from the second material, the material hardness of the second material. It should be noted that this shoe structure is merely an example of the shoe structure of the present invention, as it is designed to be greater than the material hardness of the first material.

As mentioned above, the unique midsole (14) structure made from two different materials, such as two foamable EVA materials, helps to provide the golfer with high stability and balance on various surfaces. However, it is recognized that other midsole and shoe structures can be used without departing from the spirit and scope of the invention.

For example, in another embodiment of the midsole structure, a fiber reinforced composite plate is placed on the midsole. More specifically, as shown in the exploded view of FIG. 12, in this example, the midsole is a fiber arranged between the upper and lower regions (28, 30) of the midsole (14). Includes reinforced composite plate (32). This example of a shoe (10) comprising a fiber reinforced composite plate (32) has a relatively higher structural rigidity than the shoe example described above. However, all examples of the shoe (10) of the present invention provided high stability and traction. The shoes of the present invention can hold and support the medial and lateral sides of a golfer's foot as they transfer weight during a golf shot. The shoes provide the golfer with a stable platform and help maintain balance when making shots on the course. The shoe provides golfers with high structural support, but does not sacrifice flexibility, traction, and other golf performance characteristics. Therefore, the golfer can walk and play the course and comfortably perform other golf activities.

Different embodiments of the golf shoe of the present invention provide both a high level of stability and traction, as well as a high level of forefoot flexibility. The shoe provides stability and traction, so there is no slippage and the golfer can maintain balance when swinging the club. At the same time, the flexibility of the shoes allows golfers to walk and play the course and perform other golf activities comfortably . Returning to FIGS. 9 and 10A-10E, the high stability and traction of the golf shoe (10) of the present invention is shown.

For example, with reference to FIGS. 13-19C, another embodiment of the midsole structure of the golf shoe of the present invention is shown. This version of the midsole (14) differs from the midsole structure discussed above by further including a fiber reinforced composite plate (32) located between the upper (28) and lower (30) regions. This midsole laminated structure, including the fiber reinforced composite plate (32), is described in more detail below. The golf shoe (10) including the fiber-reinforced composite plate (32) in this embodiment has a relatively higher structural rigidity than the above-mentioned shoe not including the composite plate (32). This composite shoe (10) provides the golfer with a stable platform and helps to maintain balance when making shots on the course. The shoe (10) provides the golfer with high structural support, yet without sacrificing flexibility, traction, and other golf performance characteristics.

For example, during normal golf play, a golfer makes shots at a wide variety of clubs. When a golfer swings the club to shift weight when making a shot, the foot absorbs tremendous force. Often, when right-handed golfers are addressing the ball, their right and left feet are in a neutral position. When the golfer makes a backswing, the right foot pushes down on the anterior foot and the medial area of the heel, and when the right knee remains pushed, the right foot creates torque on the ground to resist the rotation of the outer foot. Following the shot, the golfer's left shoe rolls from the inside of the left foot (medial, or inside) to the outside of the left foot (lateral, or outside). Meanwhile, their right shoe bends to the forefoot at the same time and spins internally as the heel rises.

This example of a shoe (10) comprising a fiber reinforced composite plate (32) helps to provide high stability and traction. The shoe (10) can hold and support the medial and lateral sides of the golfer's foot as it shifts weight during a golf shot. Therefore, the golfer can maintain balance while following the full swing motion of the club. More specifically, the fiber reinforced composite plate (32) helps to provide greater flexural rigidity in the shank (foot bridge) (66). The composite fiber plate (32) helps to provide the shoe (10) with high mechanical strength and structural integrity and does not allow excessive twisting or rotation of the shoe. Therefore, the shoe (10) has good torsional stability. At the same time, the shoe (10) has good forefoot flexibility, which allows the golfer to walk and play the course and perform other golf activities comfortably. This version of golf shoes has several elements that help give it a high level of stability and traction, as well as a high degree of flexibility.

First, as shown in FIG. 13, in this shoe example, the outsole also has an X-shaped structure as described above, which has high flexural rigidity on the shank (foot bridge) of the shoe outsole. Helps to provide. The shape and construction of the shank (footbridge) helps to provide rigidity and structural support to the outsole. That is, as shown in FIG. 18, the traction member is attached to the track A extending from the inner periphery of the forefoot to the outer periphery of the hindfoot region through the midfoot region. The opposing traction member is attached to a track B that extends from the outer periphery of the forefoot through the midfoot region to the medial periphery of the hindfoot region. Therefore, track A and track B intersect each other in the central region of the foot. Tracks A and B form an X-shaped pattern on the central foot. This X-shaped structure and shape helps to increase the rigidity of the shoe outsole shank (foot bridge). The X-shaped pattern helps to form a bridge between the anterior and posterior foot regions, support the midfoot region, and provide greater flexural rigidity. Further, in the example of the outsole shown in FIG. 18, as described above, there are type 1, type 2, type 3, type 4, and type 5 traction members.

Second, as shown in FIGS. 14-17, the shoe midsole of this example is also made using two different materials as discussed earlier. For example, EVA foams that are relatively soft and flexible and EVA foams that are relatively hard and rigid. It supports the midfoot region, where an X-shaped structure is arranged. The lower region (30) of the midsole forms the sidewalls of the midsole, and these stiff and strong sidewalls serve to hold and support the inside and outside of the golfer's shoe, as described above.

Third, as discussed again with reference to the exploded view of FIG. 13, this version of the midsole is a fiber placed between the upper and lower regions (28, 30) of the midsole (14). Includes reinforced composite plate (32). The arrangement of the fiber reinforced composite plate (32) with respect to the upper and lower regions (28, 30) of the midsole will be described in detail below.

The fiber reinforced composite board (32) contains a bonding matrix (resin) and reinforcing fibers. The bonded polymer may be a thermosetting material such as epoxy or rubber. Thermoplastic resins such as polyester, polyolefin, nylon and polyurethane can also be used. Preferably, carbon fibers such as graphite are used as reinforcing fibers. In addition to or in place of carbon fibers, other fibers such as aramid (eg, Kevlar ™), aluminum, or glass fiber can be used. Fiber reinforced composite boards can be manufactured using standard techniques for impregnating reinforced fibers with a resin material such as epoxy. This resin is used as a matrix for binding reinforcing fibers. These impregnated materials can be stacked to form a laminated structure such as a plate that is cured at a high temperature to solidify the composite material. The obtained fiber-reinforced composite plate is lightweight and has excellent mechanical properties such as high rigidity, high tensile strength, and low weight-to-strength ratio. As mentioned above, the midsole (14) has a sandwich-like or laminated structure, and the fiber reinforced composite plate (32) has a relatively soft foamable upper region (28) and a relatively hard foamed lower region (30). ) Is placed between.

In FIGS. 19A-19C, the composite plate (32) is shown arranged so as to extend from the front end (52) to the rear end (54) of the midsole (14). The foot (60) is shown placed on the shoe (10). In one version, as shown in FIG. 19A, the composite plate (32) is located relatively close to the forefoot (62) (eg, in the range of about 2 to about 6 mm, preferably about 4 mm). Has one end (front) located at a distance). On the other hand, the composite plate (32) has a second end (rear portion) on the opposite side located at a position relatively far from the rear foot portion (64) (for example, a distance in the range of about 12 to about 16 mm). Have. That is, the composite plate (32) is located relatively far from the ground at the front of the shoe (10) and relatively close to the ground at the rear of the shoe. This arrangement of composite boards (32) in the shoe structure helps the shoe (10) provide the golfer with a stable platform. This arrangement of composite plates (32) in the laminated construction of the midsole (14) helps support the foot and gives the golfer an improved balance.

In the second version, as shown in FIG. 19B, the composite plate (32) is shown to extend from the front end (52) to the rear end (54) of the midsole, which is essentially shown. It is located on the upper surface of the midsole structure (14). The first and second ends of the composite plate (32) are located near the forefoot (62) and hindfoot (64) regions of the midsole (14), respectively. That is, in this shoe structure, the composite plate (32) is located relatively far from the ground in both the front foot (62) and rear foot (64) regions.

In the third version, as shown in FIG. 19C, the composite plate (32) is arranged and shown to extend from the front end (52) to the rear end (54) of the midsole and has a midsole laminate structure. It is essentially centered between the top and bottom surfaces of (14). The composite plate (32) is arranged approximately equidistant between the front foot region (62) and the ground, and approximately equidistant between the rear foot region (64) and the ground. The composite board (32) has one end (front) located at a mid distance of the forefoot (62). On the other hand, in the composite material plate (32), the second end portion (rear portion) opposite to the rear foot portion (64) is located at a medium distance. That is, in this shoe structure, the composite board (32) is arranged at a substantially central position of the midsole (14) laminated structure.

In the fourth version, as shown in FIG. 19D, the composite plate (32) is shown to extend from the front end (52) to the rear end (54) of the midsole, which is essentially shown. It is located on the lower surface of the midsole structure (14). The composite plate (32) is located far away from both the front foot (62) and the rear foot (64) of the midsole (14). That is, in the structure of this shoe, the composite plate (32) is located relatively close to the ground in both the front foot (62) and rear foot (64) regions.

The moment of inertia in the region of the fiber reinforced composite plate (32) should also be considered. In general, the moment of inertia of a region is a geometric feature that reflects how the points of the region are distributed with respect to any axis. The moment of inertia of the region is calculated relative to a reference axis such as X or Y, which is usually the central or neutral axis. These are R. C. Hibbeler, Statics, 14th ed. (Pearson Prentice Hall, Hoboken NJ. 2016) pp. 528-531 and Editorials of Mechanical Design in Optical Engineering, (optics. Arizona.edu) pp. See 32-36.

In the case of a standard shape such as a rectangle as shown in FIG. The moment of inertia of the region can be calculated by the following formula.
I _x = BH ^3/12
Here, B is the base of the object (horizontal), and H is the height of the object (vertical).

In this example of a rectangular cross section, bending occurs around the X-axis, which is the axis of gravity.

As shown in FIG. 21, for more complex shapes with multiple cross-sectional areas, such as the "I-beam", the parallel axis theorem can be used to find the moment of inertia. can. In these examples, the object is divided into multiple simple cross-section areas. The parallel axis theorem states that the moment of inertia of a region around an axis is equal to the moment of inertia around the parallel axis passing through the center of that region plus the square of the area and the vertical distance between the axes. Shown. Using this theorem, the individual moments of inertia of each of the three rectangular regions of the I-beam (Figure II) are calculated for one common bending axis and summed up to the moment of inertia of area of the I-beam. Can be determined in total. The parallel axis theorem shows that as the distance of the region from the bending axis increases, so does the contribution to the magnitude of the moment of inertia of the region.

In the present invention, by moving the fiber-reinforced composite plate closer to or further from the natural bending axis of the foot, the moment of inertia of area of the plate can be substantially changed according to the parallel axis theorem. In other words, the inventors have found that the bending resistance of the plate can be directionally controlled by how the plate is arranged with respect to the flexion bending shaft and the extension bending shaft of the foot.

When the fiber reinforced composite plate is placed near the flexion bending axis of the foot, the moment of inertia of area is reduced and the plate is bent more easily. Bending resistance is reduced. On the other hand, when the plate is arranged away from the flexion / bending axis of the foot, the moment of inertia of area increases and the plate can greatly resist dorsiflexion.

As shown returning to FIG. 19A, in this embodiment, the inventors have positioned the composite plate at a relatively distant distance from the foot in the posterior foot region and to the foot in the anterior foot region. It was arranged so that it could be positioned at a relatively short distance.

In this way, the composite plate of FIG. 19A is arranged so as to have high bending resistance in the heel region. Also, by arranging the board in the midsole so that the board is located relatively away from the heel, the area of the midsole can also provide more comfort and cushioning to the foot. In contrast, the composite plate in FIG. 19A is placed on the midsole so that it is very close to the foot in the anterior foot region. In this way, the plate has less bending resistance in the forefoot region. This allows a person to easily push the thumb of the foot away. This helps people walk more naturally and comfortably. The shoe feels less stiff in the anterior foot region. The front part of the outsole makes good contact with the ground when a person jumps on his foot. Furthermore, by arranging the board on the midsole so as to be positioned relatively close to the front foot, bending resistance of golf-specific actions such as when crouching with the toes when aligning the putt is reduced. The shoe is more easily flexible in this anterior foot region when the foot weight (load) acts on the board, compared to when the foot weight acts in the heel region. How is it? The inventors have discovered that the flexion bias of a shoe can be designed by placing the plates in different positions and changing the vertical distance between the plate and the foot exactly.

All of the various embodiments of the golf shoe (10) of the present invention provide both a high level of stability and traction, as well as a high level of flexibility. The shoe provides stability and traction, so there is no slippage and the golfer can maintain balance when swinging the club. At the same time, the flexibility of the shoes allows golfers to walk and play the course and perform other golf activities comfortably. Returning to FIGS. 10A-10E , the high stability and traction of the golf shoe of the present invention on various surfaces is shown.
