A finger sack constituted of a material that has rubber elasticity is fitted and fixed to a surface (front surface) of the tip part of the finger parts.

Description

athletic gloves

TECHNICAL FIELD The present invention relates to an athletic glove, which is worn by a player on the hand of the player who pitches or throws a ball.

In baseball games including hardball baseball, softball baseball, and softball, pitchers, catchers, and fielders generally use their bare hands to pitch and throw, but this prevents injuries to the fingertips that players suffer from pitching and throwing. There is an urgent need to do this, and it is a requirement of the times to prevent injuries from being hit by pitches or batted balls with bare hands, to protect the health of players, and to manage the sanitary aspects of baseball games.
However, according to the current rules of hardball baseball, pitchers are prohibited from wearing gloves due to the prohibition in Item 6.02 (c)(7) of the Official Baseball Rules, and catchers and fielders are also prohibited from wearing gloves according to the Official Baseball Rules. According to Rule 3.01, players are prohibited from intentionally soiling the ball, so there is no custom in baseball for players to wear gloves on the throwing hand; Gloves that are intended to be worn on the hand for pitching or throwing are not on sale, and therefore, players rarely wear gloves on the hand that is used for pitching or throwing, even in practice.

However, since both amateur and professional players repeatedly throw and throw balls that spin the ball violently with their fingertips, the friction with the ball causes blood blisters to form on the fingertips and pads of the fingers. At present, there are cases where people suffer from injuries such as the skin torn, the skin on the fingers peeling off, the nails cracking, and the nails digging into the fingers (that is, the nails digging into the side edge of the nail plate).
For example, if a pitcher has a torn bloody blister on his fingertip, the blood and body fluids oozing from the injured area will adhere to the surface of the ball, and when the batter hits the ball, the blood and body fluids on the pitch will be released into the bat. If the ball becomes a foul fly, the ball may be picked up by a spectator, or a player may catch the ball with a mitt or glove during play, and the ball may stick to the hand of the pitcher or thrower. Since the ball is picked up and thrown, there is a possibility that blood or body fluids on the ball may get onto the mitt, glove, throwing pitcher, or the pitcher's hand, which has raised hygiene issues.

Furthermore, in the case of a pitcher, when a batted ball comes toward the pitcher, the pitcher stands on one leg immediately after completing the pitching motion, so he is unstable and cannot catch the batted ball with his glove in time, and the pitcher is unable to catch the batted ball in time. There are cases where the hand on the pitcher's side is directly hit by the ball, and there are also cases where the hand on the pitcher's side reflexively tries to catch the ball or knock it off. Due to the close proximity of the ball, the ball can reach speeds of more than 160 km/h, and the player's bare hands made him vulnerable to injuries such as bruises, lacerations, and fractures to his hands and fingers.

Furthermore, if you are a catcher, if a foul chip or a one-bound pitch hits your hand without a mitt, or if you touch the ball with your hand during a cross play on home plate, the runner's If you come into contact with the spikes of your shoes, or if you are a fielder, if you are hit by an irregularly bouncing ball on your hand that is not wearing a mitt or glove, your bare hands may cause lacerations, bruises, or fractures to your hands or fingers. , problems such as peeling off nails and cracking of nails, which can easily lead to injury, could not be avoided.

For example, Patent Document 1 discloses a main body part provided so as to cover at least a part of the palm, a fourth finger part connected to the main body part and provided so as to be able to accommodate a fourth finger, and a fourth finger part provided to accommodate the fourth finger. a fifth finger connected to the main body and provided so as to be able to accommodate the fifth finger; The side surface area located on the finger side includes a first non-slip area having a higher coefficient of friction than the main body, and the first anti-slip area covers at least one of the fourth finger part and the fifth finger part. A throwing glove is described, which is provided in the side area of either one of the fingers in an area that comes into contact with a portion located between the fingertip of the fourth or fifth finger and the second joint. Patent Document 2 discloses that the surface of a raised fabric is coated with a continuous tortoise-shell pattern using silicone rubber, and the back side of the raised fabric is provided with numerous pieces of silicone rubber protruding to be applied to the palm side. A sports glove is described that has a non-slip feature in which the back side of the hand is made of elastic and stretchable fabric and is sewn together with the wrist part in a series.

For example, Patent Document 1 describes a glove for throwing that can prevent the glove from slipping off during throwing. However, these gloves have the disadvantage that they are not sufficient to prevent injuries such as blood blisters on the fingertips and finger pads, tearing of the skin of the blisters, and peeling of the skin of the fingers, and that they do not allow accurate control of the ball. There are some serious inconveniences. This is because, for example, even if the fingers are made of a knitted fabric and a knitting method is used in which polyurethane threads appear on the inner surface of the knitted fabric of the fingers, in hardball baseball, for example, the initial speed exceeds 140 km/h, etc. This is because when pitching or throwing a ball close to that of the ball, the polyurethane thread alone does not have enough frictional force, and the fabric shifts against the abdomen of the finger on the inside of the finger. The reason why it is difficult to accurately control the ball is due to the phenomenon in which the fabric shifts and moves against the abdomen of the finger on the inside of the finger.
Regarding the gloves shown in Patent Document 2, a continuous tortoiseshell pattern is coated with silicone rubber to prevent slipping down to the fingertips, and if it is a bowling ball, sufficient contact area with the ball, including the palm of the hand, is ensured. However, considering the case of hardball baseball, for example, the ball is thrown by applying spin to the ball with the fingertips at the moment of release, so the area of contact between the silicone rubber at the fingertips and the ball is small. For example, when pitching or throwing a ball with full force, such as an initial velocity exceeding 140 km/h, the fingertips and the ball slip, making it inconvenient to control the ball accurately. are used on the palm side and the pads of the fingers, but brushed fabrics such as non-woven fabrics, synthetic leather, and fibers have poor elasticity, making it difficult for the fingers to come into close contact with the back side of the raised fabrics. Even with anti-slip gloves, your fingers may move and slip inside the glove to avoid injuries such as blood blisters forming on the fingertips or pads of the fingers, the skin of the blisters breaking, or the skin of the fingers peeling off. has the disadvantage of not being sufficient. Furthermore, since the palm side and the pad side of the fingers are made of raised fabric, heat tends to accumulate, which is disadvantageous in that the wearer may feel uncomfortable depending on the temperature of the environment in which it is used.

Accordingly, the present invention provides an example of an athletic glove that, when worn by a pitcher, catcher, or fielder in a baseball game including hardball baseball, softball baseball, or softball, on the hand of the person pitching or throwing the ball. Protects the fingertips of the fingers from injury (i.e. blood blisters, torn blood blisters, skin peeling of the fingers, cracked nails, nails digging into the fingers, etc.) and provides precise control similar to bare hands. To provide a glove which prevents the fabric covering the fingers from shifting against the fingers, prevents the fingertips from slipping against the ball, and ensures breathability when pitching or throwing a ball.

The present invention relates to an athletic glove, and in particular, a glove worn by pitchers, catchers, and fielders on the hands of pitchers and throwers in baseball games including hardball baseball, softball baseball, and softball is taken as an example, and will be explained below. I will do it.

Embodiments of the present invention will be specifically described with reference to the drawings. However, these embodiments are merely examples of the present invention, and should not be construed to limit the technical scope of the present invention. included in the technical scope of

The following embodiments describe right-handed gloves. However, the present invention can also be applied to left-handed gloves, and the effects are the same regardless of whether the gloves are used on the left or the right, so the description of the embodiments regarding the left-handed gloves will be omitted. Note that the left-handed glove has a shape that is a mirror inversion of the right-handed glove.

As embodiments of the gloves of the present invention, six types of gloves having different structures of the finger cots at the tips of the fingers are shown as gloves 1 to 6. The structures of the six types of finger cots are as follows: Glove 1 is shown in a sectional view taken along line AA' in FIG. 3, Glove 2 is shown in a sectional view taken along line BB' in FIG. Glove 4 is shown in the cross-sectional view taken along line C′, glove 5 is shown in cross-sectional view taken along line DD′ in FIG. 11, glove 5 is shown in cross-sectional view taken along line E-E′ in FIG. Each is shown as a schematic structural diagram in the cross-sectional view along the line. Gloves 1 to 6 differ in the shape of the knitted fabric of the finger part other than the finger cot part, and the knitted fabric of the finger part of Glove 1, Glove 2, Glove 4, and Glove 5 is a knitted fabric 50 having fingertips. However, the knitted fabric 90 is used for the finger parts of gloves 3 and 6, and the knitted fabric 90 does not have fingertips, but is located near the first joint of the finger or between the first and second joint. It refers to knitted fabric without fingers.

The palm side of glove 1 is shown in FIG. 1, and the back side of the hand is shown in FIG. , Gloves 1 to 6 are made of the same material and structure for the finger parts excluding the finger cots, the central part of the palm and back of the hand, and the arm parts. 6, FIG. 8, FIG. 10, FIG. 12, and FIG. 14 only show views of the palm side, and all views of the back of the hand are omitted. 6, FIG. 8, FIG. 10, FIG. 12, and FIG. 14 are given the same reference numerals as in FIG. 1, except for the finger cots and the knitted fabrics of the finger portions. Further, regarding the case where a large number of protrusions are arranged on the finger portions excluding the finger cots and the central portion, only the glove 1 is shown in FIG. 4 for the palm side and in FIG. 5 for the back side of the hand. When a large number of protrusions are arranged on the palm side and the back side of the hand, the materials and structure of the parts of gloves 2 to 6 except for the finger cots are the same as those of glove 1, so they will be omitted.
Note that the term "emboss" is often used in commercially available gloves, for example, but the term "protrusion" is used here.

The glove 1 will be described with reference to FIGS. 1 to 5, including a finger cot, a finger portion excluding the finger cot, a central palm portion, a back of the hand, and an arm portion. Gloves 2 to 6 all have finger cots that are different from glove 1, so the finger cots will be explained. However, the explanation of the finger portions, palm portion, back of the hand, and arm portion of gloves 2 to 6 excluding the finger cot portions will be omitted. This is because the six types of gloves (Gloves 1 to 6) have different materials and structures for the fingers excluding the finger cots, the central part of the palm and back of the hand, and the arms, except for the shape of the fabric of the fingers. This is because the same thing applies, and once glove 1 is explained, it can be considered that the explanation has been completed.

The finger fabric 50 used in gloves 1, 2, 4, and 5 and the finger fabric 90 used in gloves 3 and 6 differ only in the presence or absence of fingertip fabric. Since the material and structure are the same, the explanation of the material and structure of the fabric 50 will be applied to the fabric 90 as is, and the explanation of the material and structure of the fabric 90 will be omitted.

(About the breathability and bursting strength of the glove fabric)
FIG. 1 is a view of the palm side of the glove 1, and FIG. 2 is a view of the back side of the glove 1. The finger fabric 50 may be made of knitted fabric or elastic/stretchable fabric at least for the abdominal area, but is preferably made of knitted fabric or elastic/stretchable fabric up to the ventral side, including the dorsal side of the finger. More preferably, the entire fabric of the finger portion is made of knitted fabric or elastically stretchable fabric.
As shown in Figure 19, the ventral side of a finger refers to the side below the half of the cross section of the finger (i.e., the palm side), and the dorsal side of the finger refers to the side above the half (that is, the back of the hand). The approximate areas of the back, abdomen, and finger side are also shown in Figure 19.
Since at least the abdominal part of the finger fabric 50 is made of knitted fabric or elastic/stretchable fabric, the fabric expands and contracts in accordance with the movement of the finger, making it easier for the fabric 50 to come into close contact with the abdominal area of the finger. .
A member 100 having rubber elasticity is partially arranged on the ventral back surface of the fabric 50 of the finger portion in FIG. 1, or a large number of protrusions 101 having rubber elasticity are arranged. It has a non-slip feature to prevent fingers and the fabric 50 from slipping. In FIGS. 5 and 19, the member 100 has a band shape and is arranged with a gap, and an example of the arrangement of the protrusions 101 is shown in FIG. 20.
When the member 100 is placed on the ventral side as shown in FIG. 19, or when the protrusion 101 is placed on the ventral side as shown in FIG. 20, the fabric 50 is in close contact with the abdomen of the finger. The member 100 or protrusion 101 whose main purpose is to prevent slipping comes into close contact with the abdomen of the finger, and can prevent the fabric 50 from slipping off the finger when pitching or throwing a ball. Since the dough 50 does not shift and move from the fingers, the finger cots fixed to the dough 50 do not shift and move from the fingertips, so it is possible to maintain accurate control of the ball as with bare hands.

If at least the abdomen fabric of the finger fabric 50 in FIG. 1 is not made of knitted fabric or elastic/stretchable fabric, the disadvantages will be explained below. Taking hardball baseball as an example, according to Official Baseball Rules 3.01, the ball used in hardball has a circumference of 9 inches to 9 and a quarter inches (22.9cm to 23.5cm), that is, a diameter of is about 7.3cm to 7.5cm, but if you observe a player grasping a hardball baseball ball with his bare hand, for example with his index finger, the distance from the third joint of the index finger to the point where it contacts the ball at the tip of the finger. In contrast to L1, which is measured as the outer circumference of the ball, length L2, which is measured from the third joint of the index finger to the point where the fingertip was in contact with the ball when the index finger is stretched straight, is longer than L1, and is a hard baseball club. When measuring the L2/L1 value of five university students (height 170cm to 185cm), the results showed that (L2/L1) was approximately 1.1 for all five students. The result was that the fingers were about 10% longer when they were stretched straight, but this is because the first and second joints on the abdomen of the fingers do not come into contact with the ball.

Next, the glove 1 is made of a fabric other than knitted fabric or elastic/stretchable fabric for the entire finger fabric 50 (the fabric is artificial leather, and a band-shaped silicone rubber is placed on the back side of the ventral side as a non-slip member 100). Five university students from the above-mentioned hardball baseball club were prepared and had them wear the gloves, and while they were wearing the gloves up to their fingertips, they were asked to grasp a hardball ball, and the condition of the index finger of the glove was observed. As a result, since the fabric does not have elasticity, the fabric located near the first and second joints on the ventral side does not stick tightly to the fingers and floats, causing wrinkles, twists, and kinks on the ventral side. It was observed that there were. Furthermore, depending on the strength with which you grip the ball, a force is exerted that pushes the finger sack part of the fingertip outward from the fingertip, causing the finger and the finger sack part to shift several millimeters, creating a gap at the inner tip of the fingertip. was reported. When pitching or throwing a ball from this state, pitching or throwing is when the fingers extend straight and spin the ball from the fingertips. Since the fingers try to return to their original positions inside the sack and shift, it is inconvenient to perform accurate control similar to bare hands. If a finger slips inside the toe cot, there will be friction between the abdomen of the finger and the inside of the toe cot when pitching, and, for example, the sole of the foot will get chafed partially in ill-fitting shoes. Since this is the same phenomenon as in the first joint, it is thought that it may cause injuries such as the formation of blood blisters on the fingertips or the abdomen of the fingers beyond the first joint, the skin of the blood blisters breaking, and the skin of the fingers peeling off, which is inconvenient. It is.

Furthermore, it has been confirmed that when the ball is gripped, the phenomenon in which the fingers move even a few millimeters within the finger cot causes discomfort to the glove wearer. When gripping a ball, if the wearer's fingers move even a few millimeters inside the finger cot, the wearer recognizes this as a sign that the player will be unable to accurately control the ball. This is inconvenient because it reminds the wearer of a wild pitch, and may cause mental stress to the wearer.
Note that the size of a person's fingers does not necessarily depend on height, and the length and shape of the fingers vary from person to person, so although it is assumed that the above L2/L1 value is not 1.1, is never less than 1, so the disadvantages described above should be interpreted as having universal elements.

In the fabric 50 of FIG. 1, at least the abdominal fabric may be made of knitted fabric or elastic/stretchable fabric, but it is preferable that the fabric 50 is made of knitted fabric or elastic/stretchable fabric up to the abdominal side. If the ventral side is made of knitted fabric or elastic stretchable fabric, and the back side of the finger is not knitted fabric or elastic stretchable fabric, the fabric on the back side of the finger is made of, for example, woven fabric, nonwoven fabric, natural leather, synthetic leather, artificial leather, etc. It is possible that When the fabric 50 is composed of a plurality of fabrics, it is necessary to join them together, and possible joining methods include sewing, welding, adhesion, etc. In addition, when the fabric 50 is composed only of knitted fabric or elastic/stretchable fabric, the elastic pressure of the fabric 50 is uniformly applied to the entire finger, making it easier to obtain a good fit, and reducing production costs since there is no need for sewing, welding, or gluing. There are benefits. On the other hand, for example, if the fabric on the back of the finger is made of woven fabric, non-woven fabric, natural leather, synthetic leather, artificial leather, etc., it has a protective function that reduces the degree of injury when the back of the finger is hit by a batted ball, a pitched ball, or a thrown ball. It has the advantage of being strengthened.

The fabric 10 shown in FIG. 1 on the palm side of the glove 1 and the fabric 20 shown in FIG. 2 on the back side of the glove 1 are preferably made of knitted fabric or elastic stretch fabric. Since the fabric 10 and the fabric 20 are knitted fabrics or elastic and stretchable fabrics, the fabric 10 and the fabric 20 have elasticity, and the fabric on the palm side and the back side of the hand expands and contracts according to the movement of the hand and fingers. , less stress on hands and fingers. In addition, the fabric 10, fabric 20, and finger fabric 50 may be continuous fabrics, but if the fabric 10, fabric 20, and fabric 50 are separate fabrics, they need to be joined, but the joining method Possible methods include sewing, welding, and gluing. Because the fabric 10, fabric 20, and fabric 50 are continuous fabrics or fabrics that are joined, even if centrifugal force is applied to the finger portion during pitching or throwing, the fabric 50 will remain the same as the fabric 10, the fabric 50. 20, it is possible to further prevent the fabric 50 from slipping and moving with respect to the fingers.

The air permeability of the fabric 10 shown in FIG. 1 on the palm side of the glove 1, the fabric 20 shown in FIG. It is preferable that it is more than meter/square centimeter/S. When the air permeability of the fabric described above is 20 cubic centimeters/square centimeter/S or more, the glove 1 is provided with breathability, and heat buildup in the palm, back of the hand, and fingers can be prevented.

The air permeability of the fabric 10 shown in FIG. 1 on the palm side of the glove 1, the fabric 20 shown in FIG. /S or more, more preferably 40 cubic centimeters/square centimeter/S, more preferably 50 cubic centimeters/square centimeter/S, still more preferably 60 cubic centimeters/square centimeter/S or more. It is even more preferable that it is, and it is especially preferable that it is 70 cubic centimeters/square centimeter/S or more.
By setting the lower limit of the air permeability of the fabric described above to the above range, the glove 1 can easily dissipate heat from the hands, making it easier for the wearer to pursue comfort. Further, the upper limit value of the air permeability of the fabric described above can be, for example, 200 cubic centimeters/square centimeter/S or less, 150 cubic centimeters/square centimeter/S or less, or 100 cubic centimeters/square centimeter/S or less. .
In addition, when using gloves in conditions where the temperature is low, such as during the winter season, when the player feels cold, fabrics with relatively low breathability, such as 20 cubic centimeters/square centimeters/S, should be used. It is thought that the fabric is preferred.
In addition, the air permeability of the fabric 10 shown in FIG. 1 on the palm side of the glove 1, the fabric 20 shown in FIG. It doesn't have to be a certain degree, it can be different for each fabric.

JIS L1096 8.18 The bursting strength of the fabric 10 of FIG. 1 on the palm side of the glove 1, the fabric 20 of FIG. , 250 KPa or more is preferable. If it is 750KPa or less, the size of the stitches of the fabric will be appropriate, making it easier to ensure the required breathability and elasticity, and if it is 250KPa or more, it will be possible to ensure the strength and durability of the fabric. can.

It is preferable to have a member 35 having elasticity. Further, FIG. 3 shows a glove 1 in which a large number of protrusions 11 having rubber elasticity are arranged instead of the member 30 having rubber elasticity. In the case where members 30 to 35 having rubber elasticity are arranged on the fabric 10 of the palm part as shown in FIG. In both cases where the members 31 to 35 having the rubber elasticity are arranged, it is preferable that the coverage area ratio of the entire palm of the hand by the members having rubber elasticity is 75% or less. Possible methods for fixing the members 30 to 35 and the protrusion 11 to the fabric 10 of the palm include welding, adhesion, and sewing.
By arranging members 30 to 35 having rubber elasticity on the fabric 10 of the palm part of the glove 1 as shown in FIG. 1, or by arranging a large number of protrusions 11 having rubber elasticity as shown in FIG. By arranging the members 31 to 35 having rubber elasticity, when the palm receives a batted ball, a pitched ball, a thrown ball, etc., the degree of impact received by the palm is reduced, and injuries that may be sustained to the palm can be eliminated or injuries can be reduced. In addition, since the coverage area ratio of the entire rubber elastic member in the palm part is 75% or less, the fabric 10 in the palm part can ensure breathability.

When the glove 1 has members 30 to 35 having rubber elasticity in the fabric 10 of the palm part as shown in FIG. It is preferable to prepare a plurality of members 30 to 35 and arrange them with gaps between them. By arranging the plurality of members 30 to 35 with gaps in the fabric 10 on the palm of the hand, it becomes easier to adjust the coverage area ratio of the fabric 10 by the members 30 to 35, and the fabric 10 also adapts to the movement of the wearer's palm. It becomes easier to expand and contract in response to

The ratio is preferably 30% or more, more preferably 35% or more, even more preferably 40% or more, even more preferably 45% or more, and even more preferably 50% or more. Particularly preferred.
By setting the lower limit of the coverage area ratio within the above range, the wearer of Glove 1 can reduce the degree of impact that the palm receives when the palm receives a batted ball, a pitched ball, a thrown ball, etc. The injury can be eliminated or the severity of the injury reduced. If the coverage area ratio is less than 30%, only a small amount of the members 30 to 35 and the protrusions 11 can be arranged, and if you try to grip the ball using the palm of your hand, the ball will tend to slip, which may cause problems when hitting or pitching the ball. , when the palm of the hand receives a thrown ball, etc., the degree of mitigation of the impact received by the palm is reduced, and there is a disadvantage that it is not possible to eliminate or reduce the degree of injury that may be sustained to the palm.

The thickness of the rubber elastic members 30 to 35 disposed on the fabric 10 of the palm of the glove 1 in FIG. 1 is preferably 300 μm or more and 3000 μm (3 mm) or less. By setting the thickness of the members 30 to 35 to 300 μm or more, when the wearer of the glove 1 receives a batted ball, a pitched ball, or a thrown ball with the palm of the hand, the degree of impact that the palm receives is reduced, and injuries that may be sustained to the palm are reduced. By reducing the thickness to 3000 μm (3 mm) or less, the weight of the glove 1 can be reduced, and at the same time, the wearer of the glove 1 can reduce the feeling when gripping the ball. The feeling of gripping a ball with bare hands can be brought closer to the feeling of gripping a ball with bare hands.

The thickness of the members 30 to 35 having rubber elasticity of the fabric 10 of the palm part of the glove 1 in FIG. 1 may be 300 μm or more, preferably 600 μm or more, and more preferably 1000 μm (1 mm) or more, More preferably, the thickness is 1500 μm (1.5 mm) or more. By setting the lower limit of the thickness of the rubber-elastic members 30 to 35 of the fabric 10 in the palm part to the above range, the palm of the glove 1 can be hit by a ball, pitched, thrown, etc. with the palm of the hand. It can soften the impact and eliminate or reduce the degree of injury that may be sustained to the palm of the hand.
Further, the thickness of the members 30 to 35 having rubber elasticity of the fabric 10 of the palm portion may be 3000 μm (3 mm) or less, preferably 2500 μm (2.5 mm) or less, and more preferably 2000 μm (2 mm) or less. By setting the upper limit of the thickness of the rubber elastic members 30 to 35 of the fabric 10 of the palm within the above range, the weight of the glove 1 can be reduced, and at the same time, the wearer of the glove 1 can easily grasp the ball. The feeling when gripping a ball with bare hands can be brought closer to the feeling when gripping a ball with bare hands.
Note that by making the thickness of the member 35 thicker than the others, the hamate and pisiform bones, which are susceptible to injury, can be further protected.

The protrusions 11 disposed on the fabric 10 of the palm of the glove 1 in FIG. Squares or squares with rounded corners measuring 1 mm or more and 3 mm or less, polygons or polygons with rounded corners or circles, ellipses, and curves and straight lines that have an area equivalent to a square with a side of 1 mm or more and 3 mm or less. The height is preferably about 0.5 mm to 3 mm, and the protrusions are preferably arranged regularly at intervals of about 1 mm to 2 mm, and the protrusions of approximately the same shape and size are preferably arranged. . By having the shape and height of the protrusions 11 as described above, and by making the protrusions 11 regularly arranged at intervals of about 1 mm to 2 mm and having approximately the same shape and dimensions, the palm of the hand is breathable. In addition, since pressure can be applied evenly to the contact surface with the ball, the ball can be easily gripped.Furthermore, when the wearer of glove 1 receives a batted ball, pitched ball, or thrown ball directly to the palm of the hand, , it is possible to reduce the degree of impact that the palm receives, and eliminate or reduce the degree of injury that the palm may sustain.

The materials configuring the members 30 to 35 arranged on the fabric 10 of the palm of the glove 1 in FIGS. 1 and 3 and the protrusion 11 include, for example, natural rubber, synthetic natural rubber, silicone rubber, nitrile rubber, urethane rubber, Examples include EPDM, polyurethane resin, vinyl chloride resin, etc., and by selecting the above-mentioned materials, it is possible to avoid damaging the surface of the ball used.
Among these, it is preferable that the materials composing the members 30 to 35 of the fabric 10 of the palm and the protrusion 11 contain silicone rubber. Silicone rubber has almost no reaction to body tissues, is odorless, and is physiologically inert, so it is suitable for use in products that come in direct contact with the human body (such as baby bottle nipples, mouthpieces, medical instruments, and medical materials). The members 30 to 35 and the protrusion 11 may contain silicone rubber because it gives the wearer of the glove 1 a sense of security because it is widely used, and the material maintains elasticity even at low temperatures. This is a favorable reason. By containing silicone rubber, the materials composing the members 30 to 35 of the palm fabric 10 and the protrusions 11 maintain their elasticity even in low temperature environments, so they can be used regardless of the season. In addition to avoiding scratches on the surface of the ball being used, the glove 1 also enhances the anti-slip effect, making it easier for the wearer to grip the ball, and allowing the fabric 10 to move in response to the movements of the wearer's palm. To make it difficult to prevent free expansion and contraction.

When there are multiple members 30 of the fabric 10 on the palm of the glove 1 in FIG. Possible shapes include a combination of curved lines and straight lines. Further, the shape of the member 30 may include a portion having one or more holes, and the shape of the hole may be a polygon such as a square, a shape with rounded corners of a polygon, a circle, an ellipse, or a curved shape. A shape that is a combination of a straight line and a straight line can be considered, and is preferable because it provides an anti-slip effect when the ball is gripped. It is also preferable to provide protrusions, grooves, wrinkles, roughness, etc. on the surface of the member 30 having rubber elasticity to provide a non-slip effect. Furthermore, there may be a cut in the member 30 that extends vertically from the surface to the palm of the hand. By providing the cuts, the movement of the fabric 10 can be made smoother.

When there are multiple members 30 of the fabric 10 on the palm of the glove 1 in FIG. It is preferable to provide exposed lines 36, 37, and 38 having a width of approximately 2 mm to 3 mm so that the fabric is exposed along the exposed portions, avoiding being covered by the member 30.
By providing exposed lines 36, 37, and 38 along the parts corresponding to the thenar skin line, proximal palm skin line, and distal palm skin line of the palm, the fabric 10 of the palm can be easily adjusted according to the movement of the palm. can be made easier to bend. Since the exposed lines 36, 37, and 38 are curved lines, when a plurality of members 30 are provided, it is not necessary that all the members 30 have the same shape and the same size. By not having the same shape and size, the exposed lines 36, 37, and 38 can be easily exposed.

The members 31 to 34 arranged to cover the finger balls of the second to fifth fingers of the fabric 10 on the palm of the glove 1 in FIG. It is preferable to use a rounded shape, a polygon having an area equivalent to a rectangle with sides of about 12 mm to 18 mm, a shape with rounded corners of a polygon, a circle, an ellipse, and a shape that combines a curved line and a straight line.
When considering how pitchers, catchers, and fielders grip the ball before pitching or throwing, they grasp the ball with the pads or finger sides of their second to fifth fingers, and hold the ball on the tips of their fingers. A common method is to press down on the ball to stabilize it and place your thumb on it to prevent it from falling. Therefore, by providing the members 31 to 34 with the areas described above, the anti-slip effect is enhanced and the wearer of the glove 1 can easily grip the ball.
Furthermore, it is preferable to provide protrusions, grooves, wrinkles, texture, etc. on the surfaces of the members 31 to 34 to enhance the anti-slip effect, and furthermore, provide vertical cuts from the surfaces to the palms of the members 31 to 34 to prevent movement of the fabric 10. There may be some parts that are made smoother. By providing the cuts, the movement of the fabric 10 can be made smoother.

The member 35 arranged to cover the hamate hook and pisiform bone of the fabric 10 on the palm of the glove 1 in FIG. It is preferable that the shape is circular, oval, or a combination of curved and straight lines. Among the carpal bones, the hamate and pisiform bones of the palm are more susceptible to injuries such as fractures, and by protecting them with the member 35 having the area described above, they can be protected from the impact of being hit by a batted ball, a pitched ball, a thrown ball, etc. This can eliminate or reduce the degree of injury that the hook and pisiform bones may sustain.
Further, it is preferable to provide protrusions, grooves, wrinkles, roughness, etc. on the surface of the member 35 to enhance the anti-slip effect.Furthermore, it is preferable to provide the member 35 with a vertical cut from the surface to the palm of the hand to make the movement of the fabric 10 smoother. There may be a place where it is assumed. By providing the cuts, the movement of the fabric 10 can be made smoother.

In addition, since the hook of the palm and the pisiform bone are the parts of the carpal bones where fractures are most frequently reported, the material constituting the member 35 disposed on the fabric 10 is made of a material having rubber elasticity, For example, the protection function may be further strengthened by attaching a layer of non-woven fabric, natural leather, artificial leather, synthetic leather, etc.

(About the back of the glove)
It is preferable that the fabric 20 of the back of the hand of the glove 1 in FIG. It is preferable to have rubber elastic members 71 to 75 that cover the metacarpal head to the fifth finger metacarpal head, and it is preferable to have a rubber elastic member 76 that covers the base of the first metacarpal bone. Further, FIG. 4 shows a diagram in which a large number of protrusions 21 having rubber elasticity are arranged instead of the member 70 having rubber elasticity. In the case where members 70 to 76 having rubber elasticity are arranged on the fabric 20 of the back of the hand, as shown in FIG. In both cases where the members 71 to 76 having the rubber elasticity are arranged, it is preferable that the coverage area ratio of the entire rubber elastic member on the back of the hand is 75% or less. Possible methods for fixing the members 70 to 76 and the protrusion 21 to the fabric 20 include welding, adhesion, and sewing.

By arranging the elastic members 71 to 76, when the back of the hand receives a batted ball, a pitched ball, a thrown ball, etc., the degree of impact received by the back of the hand is alleviated, and injuries that may be sustained to the back of the hand can be eliminated or the degree of injury can be reduced. can be reduced. Further, since the coverage area ratio of the entire rubber elastic member on the back of the hand is 75% or less, the breathability of the fabric 20 on the back of the hand can be ensured.

When the glove 1 has members 70 to 76 having rubber elasticity in the fabric 20 of the back of the hand as shown in FIG. It is preferable to prepare a plurality of members and arrange the members 70 to 76 with gaps between them. By arranging the plurality of members 70 with gaps between them on the fabric 20 on the back of the hand, it becomes easier to adjust the coverage area ratio of the members 70 on the fabric 20. Further, by providing gaps between the plurality of members 70, the fabric 20 of the glove 1 can easily expand and contract, and the feeling of tightness after wearing the glove 1 can be prevented.

The area ratio covered by the members 70 to 76 having rubber elasticity of the fabric 20 of the back of the hand of the glove 1 in FIG. 2, and the area covered by the numerous protrusions 21 having rubber elasticity and the members 71 to 76 having rubber elasticity in FIG. 4. The ratio may be 75% or less, preferably 70% or less, more preferably 65% or less, and even more preferably 60% or less. By setting the upper limit of the coverage area ratio within the above range, the fabric 20 on the back of the hand can easily ensure breathability, making the glove 1 comfortable.

The coverage area ratio is preferably 30% or more, more preferably 35% or more, even more preferably 40% or more, even more preferably 45% or more, and even more preferably 50% or more. This is particularly preferred. By setting the lower limit of the coverage area ratio within the above range, when the wearer of Glove 1 receives a ball hit, pitched, thrown, etc. with the back of the hand, the degree of impact that the back of the hand receives is reduced, and the back of the hand may be affected. The injury can be eliminated or the severity of the injury reduced. If the coverage area ratio is less than 30%, only a small amount of the members 70 to 76 and the protrusions 21 can be arranged, and the degree to which the back of the hand is cushioned from impact when the back of the hand receives a batted ball, a pitched ball, a thrown ball, etc., becomes small. There is the disadvantage that it is not possible to eliminate or reduce the degree of injury that may be caused to the back of the hand.

The thickness of the members 70 to 76 of the fabric 20 on the back of the hand of the glove 1 in FIG. 2 is preferably 300 μm or more and 3000 μm (3 mm) or less. By setting the thickness of the members 70 to 76 of the fabric 20 on the back of the hand to 300 μm or more, when the wearer of the glove 1 receives a ball hit, pitched, thrown, etc. with the back of the hand, the degree of impact that the back of the hand receives is reduced, and the back of the hand is Possible injuries can be eliminated or the degree of injury can be reduced, and by setting the thickness to 3000 μm (3 mm) or less, the weight of the glove 1 can be reduced.

By setting the lower limit of the thickness of the members 70 to 76 of the fabric 10 in the palm part as described above, the degree of impact received by the back of the hand when the wearer of the glove 1 receives a batted ball, a pitched ball, a thrown ball, etc. with the back of the hand can be reduced. , can eliminate or reduce the severity of injuries that may be sustained to the back of the hand.
Further, the thickness of the members 70 to 76 of the fabric 20 for the back of the hand may be 3000 μm (3 mm) or less, preferably 2500 μm (2.5 mm) or less, and more preferably 2000 μm (2 mm) or less. By setting the upper limit of the thickness of the members 70 to 76 of the fabric 10 in the palm part as described above, the weight of the glove 1 can be reduced.

When the protrusions 21 are arranged on the fabric 20 on the back of the hand of the glove 1 as shown in FIG. 4, the shape of the protrusions is preferably a cone such as a square pyramid or a cone, and the shape and dimensions of the base of the cone are as follows: A square with a side of 1 mm or more and 5 mm or less, or a polygon with an area equivalent to a rectangle with a side of 1 mm or more and 5 mm or less, a polygon with a rounded corner, a circle, an ellipse, and a curve. It is preferable that the shape is a combination of a straight line and a straight line, the height is preferably about 0.5 mm to 5 mm, and the protrusions are preferably arranged at intervals of about 1 mm to 5 mm. By setting the shape and height of the protrusions 21 as described above, and by arranging them at intervals of about 1 mm to 5 mm, the back of the hand can ensure ventilation, and the wearer of the glove 1 can easily hit or pitch a ball. When the back of the hand is directly hit by a thrown ball, the degree of impact received by the back of the hand can be reduced, thereby eliminating or reducing the degree of injury that may occur to the back of the hand. Furthermore, unlike the protrusions 11 on the palm side, the protrusions 21 do not have the purpose of grasping the ball to be used, so the protrusions 21 do not all have to be the same size, nor do they need to be arranged regularly. For example, in areas that cover the first to fifth finger metacarpals that are prone to fractures, the first to third finger metacarpals can be covered by placing larger protrusions 21 than the others or by increasing the density of the protrusions 21. The degree of protection of the finger metacarpals to the fifth finger metacarpals may be increased.

The materials composing the members 70 to 76 of the fabric 20 on the back of the hand of the glove 1 and the protrusion 21 in FIGS. 2 and 4 are, for example, natural rubber, synthetic natural rubber, silicone rubber, nitrile rubber, urethane rubber, EPDM, polyurethane rubber, etc. Possible materials include resin and vinyl chloride resin. By selecting these materials, it is possible to avoid scratching the surface of the balls used in case of contact.
Among these, it is preferable that the materials composing the members 70 to 76 of the fabric 20 on the back of the hand and the protrusion 21 contain silicone rubber. Silicone rubber has almost no reaction to body tissues, is odorless, and is physiologically inert, so it is suitable for use in products that come in direct contact with the human body (such as baby bottle nipples, mouthpieces, medical instruments, and medical materials). The members 70 to 76 and the protrusion 21 may contain silicone rubber because it gives the wearer of the glove 1 a sense of security because it is widely used, and the material maintains elasticity even at low temperatures. This is a favorable reason. By containing silicone rubber, the materials composing the members 70 to 76 of the fabric 20 on the back of the hand and the protrusions 21 maintain their elasticity even in low temperature environments, so they can be used regardless of the season. In addition, the glove 1 can avoid damaging the surface of the ball when it comes into contact with the glove 1, and at the same time, the glove 1 can prevent the back of the hand from feeling stiff after being worn.

When there are multiple members 70 of the fabric 20 on the back of the hand of the glove 1 in FIG. Also possible are shapes that combine curves and straight lines. Among them, the part covering the first to fifth finger metacarpals is, for example, a square with a side of about 8 mm to 10 mm, or a square with rounded corners, and a side of about 8 mm to 10 mm, as shown in Figure 2. Possible shapes include a polygon with an area equivalent to a quadrilateral, a polygon with rounded corners, a circle, an ellipse, and a combination of curved and straight lines. It is preferable to arrange a plurality of them. By arranging the member 70 having the shape described above on each metacarpal bone at the above-mentioned intervals, the metacarpal bones, which are susceptible to injury, can be protected from hitting, pitching, throwing, etc., and the back of the hand. It is also possible to ensure the breathability and stretchability of the fabric 20 of the section.
Furthermore, as shown in FIG. 2, the member 70 that covers the carpal bones has a triangular shape with rounded corners of a triangle or a triangle with a side of about 6 mm to 8 mm, or a polygon with an area equivalent to a triangle with a side of about 6 mm to 8 mm. It is preferable to arrange a plurality of rubber or resin members in the shape of a polygon with rounded corners, a circle, an ellipse, a combination of curved lines and straight lines, etc., at intervals of about 1 mm to 2 mm or more.

The members 71 to 75 arranged to cover the first to fifth finger metacarpal heads of the fabric 20 on the back of the hand of the glove 1 in FIG. It is preferable to use a rectangular or polygonal shape with rounded corners, a circle, an ellipse, or a combination of a curved line and a straight line. The metacarpal heads on the back of the hand are susceptible to injuries such as fractures, and by protecting them with a member with the area described above, the degree of impact when hit by a batted ball, pitched ball, or thrown ball is reduced, and each metacarpal head is It can eliminate or reduce the severity of injuries that may be sustained.

The member 76 arranged to cover the base of the first finger metacarpal bone of the fabric 20 on the back of the hand of the glove 1 in FIG. It is preferable to use a shape that is an elliptical shape or a combination of a curved line and a straight line. The base of the metacarpal bone of the first finger on the back of the hand is susceptible to injuries such as fractures, and by protecting the base of the metacarpal bone of the first finger with the member 76 having the above-mentioned area, it can be protected against damage when hit by a batted ball, pitched ball, or thrown ball. The degree of impact can be softened, eliminating or reducing the degree of injury that may be sustained at the base of the first digit metacarpal.

Note that the first to fifth finger metacarpal heads and the base of the first metacarpal bone on the back of the hand are areas where fractures are frequently reported, so the materials constituting the members 71 to 76 arranged on the fabric 20 are The protective function may be strengthened by attaching a layer of nonwoven fabric, natural leather, artificial leather, synthetic leather, etc. on the member having rubber elasticity.

(About the structure of the fingertips of gloves 1 to 3)
The fabric 50 of the finger part of glove 1 in FIG. 1 and the fabric 50 of the finger part of glove 2 in FIG. It has finger cots 41a to 45a made of a rubber elastic member that cover the claw. FIG. 5 shows a cross section of the second finger of the glove 1 taken along line AA' in FIG. 1 as a schematic structural cross-sectional view. Note that similar cross-sectional views of the first finger, third finger, fourth finger, and fifth finger are omitted because they have the same structure as FIG. 5. Further, FIG. 7 shows a cross section of the second finger of the glove 2 taken along line BB' in FIG. 6 as a schematic structural cross-sectional view. Note that similar cross-sectional views of the first finger, third finger, fourth finger, and fifth finger are omitted because they have the same structure as FIG. 7. Possible methods for fixing the finger cots 41a to 45a to the fabric 50 include welding, adhesion, and sewing.

The fabric 50 of the finger portion of the glove 2 in FIG. 6 is a member having rubber elasticity on the back surface from the fingertip to any one of the third joints (for the first finger, between the fingertips and the second joint). It has finger cot-like backings 41b to 45b. Possible methods for fixing the finger cot-like backings 41b to 45b to the back surface of the fabric 50 include welding, adhesion, and sewing. Since the fabric 50 of the glove 2 in FIG. 6 has finger cot-like backings 41b to 45b on the back of the fingertips, the glove 2 can provide stronger protection for the fingertips than the glove 1.

FIG. 8 shows the glove 3. The finger fabric 90 of the glove 3 has a fingerless shape in which the fingertips of the fabric are cut off from the fingertip to the third joint of each finger (for the first finger, between the fingertip and the second joint). It is. The finger cots 81 to 85 are finger cots having rubber elasticity between the fingertip and the third joint (for the first finger, between the fingertip and the second joint), and the finger cots 81 to 85 are Gloves 3 are made by covering the fabric 90 so that they overlap by about 5 mm to 10 mm from the tip, and fixing the overlapped portion to the fabric 90 by welding, gluing, sewing, or the like. As for how to stack the finger cots on the fabric, it is preferable that the finger cots 81 to 85 wrap the knitted fabric 90 from above. FIG. 9 shows a cross section of the second finger of the glove 3 taken along line CC' in FIG. 8 as a schematic structural cross-sectional view. Note that similar cross-sectional views of the first finger, third finger, fourth finger, and fifth finger are omitted because they have the same structure as FIG. 9. The glove 3 can protect the fingertips from injury by having finger cots 81 to 85 at the fingertips, and since the fabric 90 has a fingerless shape, the finger cots only have the finger cots 81 to 85. The finger cot part can be made thinner than the gloves 1 and 2, and the feeling of pitching or throwing a ball with bare hands can be more closely approximated.

(About the structure of the fingertips of gloves 4 to 6)
Glove 1 in FIG. 1, glove 2 in FIG. 6, and glove 3 in FIG. 8 have no choice but to be discarded if the surface of the finger cot of even one of the five fingers wears out due to repeated pitching and throwing. Therefore, so that only the worn skin of the finger cot can be removed and replaced, the finger cot base is fixed to the fingertip, and the replaceable finger cot is fitted into the finger cot base. Gloves 4 in FIG. 10, gloves 5 in FIG. 12, and 5 in FIG. This is glove 6.
Gloves 4 to 6 can protect the fingertips from injury with the finger cots, and the glove body can be used repeatedly by replacing the worn finger cots, so they are less wasteful than gloves 1 to 3. In addition, the economic burden on the wearer can be reduced.

Glove 4 in FIG. 10 and glove 5 in FIG. 12 have finger cot base parts 41c to 45c on the finger fabric 50, and replaceable finger cots 41d to 45d having rubber elasticity are used by fitting them into the finger cot base parts. do. The finger cot base portions 41c to 45c and the finger cots 41d to 45d have a length from the fingertip to the third joint (for the first finger, from the fingertip to the second joint). FIG. 11 shows a cross section of the second finger of the glove 4 along line DD' as a schematic structural cross-sectional view. Note that similar cross-sectional views of the first finger, third finger, fourth finger, and fifth finger are omitted because they have the same structure as FIG. 11. Further, FIG. 13 shows a cross section of the second finger of the glove 5 taken along line EE' as a schematic structural cross-sectional view. Note that similar cross-sectional views of the first finger, third finger, fourth finger, and fifth finger are omitted because they have the same structure as FIG. 13. Possible methods for fixing the finger cot base portions 41c to 45c to the fabric 50 include welding, adhesion, and sewing.

The fabric 50 of the finger part of the glove 5 shown in FIG. 12 is a member having rubber elasticity on the back surface from the fingertip to the third joint (for the first finger, between the fingertip and the second joint). It has finger cot-like backings 41b to 45b. Possible methods for fixing the finger cot-like backings 41b to 45b to the back surface of the fabric 50 include welding, adhesion, and sewing. Since the fabric 50 of the glove 5 in FIG. 12 has finger cot-like backings 41b to 45b on the back of the fingertips, the glove 5 can provide stronger protection for the fingertips than the glove 4.

FIG. 14 shows the glove 6. The finger fabric 90 of the glove 6 has a fingerless shape in which the fingertips of the fabric are cut off between the fingertip and the third joint of each finger (for the first finger, between the fingertip and the second joint). It is. The finger cots 81a to 85a are finger cot base parts that have rubber elasticity from the fingertip to the third joint (for the first finger, from the fingertip to the second joint). For example, cover the fabric 90 so that it overlaps by about 5 mm to 10 mm from the tip, and fix the overlapped part to the fabric 90 by welding, gluing, sewing, etc., and attach the replaceable finger cots 41d to 45d to the finger cot base. Gloves 6 are used by being fitted into the body. Regarding the method of overlapping the finger cots on the fabric, it is preferable to overlap the finger cots 81a to 85a so as to wrap the knitted fabric 90 from above. FIG. 15 shows a cross section of the second finger of the glove 6 taken along line FF' in FIG. 14 as a schematic structural cross-sectional view. Note that similar cross-sectional views of the first finger, third finger, fourth finger, and fifth finger are omitted because they have the same structure as FIG. 15.

Because gloves 1 to 6 have finger cots, the wearer of gloves 1 to 6 can prevent blood blisters from forming on the fingertips and pads of the fingers, the skin of the blood blisters torn, and the skin of the fingers caused by pitching or throwing. Injuries such as peeling of skin, cracking of nails, and nails digging into fingers (nails digging into the side edge of the nail plate) can be avoided. Since the above-mentioned injury can be avoided, the unsanitary situation in which blood or body fluids that seep out from the affected part of the fingertip when an injury occurs can be avoided, which is conventionally caused by adhering to the surface of the ball. In addition, if you are a catcher, you may suffer from cracked or peeled nails if you receive a one-bound pitch, a foul from a batted ball, or a foul chip on your fingertip, and if you are a fielder, you may suffer from an irregular bounce from a batted ball to your fingertip. This can prevent nail cracking and finger lacerations.

Compared to gloves 1 to 3, gloves 4 to 6 allow the glove body to be reused by replacing the replaceable finger cots, and reduce waste because the glove body is not discarded. can reduce the economic burden of Gloves 1 to 3 have a structure that does not have a replaceable finger cot, so they have the advantage of being able to be used immediately without the hassle of fitting the replaceable finger cot into the finger cot base.
In addition, when a wearer uses a type of glove that does not have a replaceable finger cot, the wearer can choose from Gloves 1 to 3, which have different finger cot structures, to determine the thickness of the finger cot, the feel of the fingertips, etc. Similarly, when the wearer uses a type of glove with an exchangeable finger stall, the wearer can choose from gloves 4 to 6 with different finger stall structures. You can choose the one you like based on its thickness, feel on your fingertips, etc.

If the finger cots on gloves 1 to 6 could make the ball less slippery when pitching or throwing, pitchers would use rosin (a white powder whose main ingredients are magnesium carbonate and pine resin) to prevent slipping. can be made unnecessary. For example, in professional baseball, pitchers from both teams share rosin from rosin bags placed near the mound, which has led to concerns about hygiene. Can be done. Additionally, in professional baseball, if the pitcher is at a distance from the mound, it is permitted to lick the fingers of the pitching hand (supposedly to prevent saliva from slipping); Not only does saliva adhere to the ball, but when a pitcher who has licked his fingers touches the rosin bag, it is thought that saliva will adhere to the rosin bag, which has been pointed out as a sanitary problem, and this problem should also be resolved. Can be done.

For the finger cots of gloves 1 to 6, the four points of material, hardness, anti-slip surface structure, and wall thickness are selected to achieve the purpose of protecting the fingers from injury and preventing the ball from slipping. Since this can be prevented, it will be explained below.

(About the materials that make up the finger cot)
Finger cots 41a to 45a of glove 1 in FIG. 1 and glove 2 in FIG. 6, lining finger cots 41b to 45b of glove 2 in FIG. 6 and glove 5 in FIG. 12, and finger cots 81 to 85 of glove 3 in FIG. , finger cot base portions 41c to 45c of glove 4 in FIG. 10 and glove 5 in FIG. 12, finger cot base portions 81a to 85a of glove 6 in FIG. 14, glove 4 in FIG. 10, glove 5 in FIG. The replaceable finger cots 41d to 45d of glove 6 are all types of finger cots of gloves 1 to 6, but for all types of finger cots of gloves 1 to 6, the material constituting the finger cots is made of rubber elastic material. For example, natural rubber, synthetic natural rubber, silicone rubber, nitrile rubber, urethane rubber, EPDM, polyurethane resin, vinyl chloride resin, etc. are considered, and materials that are a mixture of the above-mentioned materials are also considered. It will be done. By selecting the above-mentioned materials or a mixture of the above-mentioned materials, it is possible to avoid damaging the surface of the ball used and the fingers. According to Item 6.02(c)(5) of the Official Baseball Rules, for example, pitchers are prohibited from damaging the ball in any way, so it is necessary to comply with that rule. can. Furthermore, by using the rubber-elastic material described above, it is possible to prevent the ball from slipping when pitching or throwing a ball used in competitions, and maintain precise control similar to that with bare hands. be able to.
Among these, all types of finger cots of gloves 1 to 6 preferably contain silicone rubber or urethane rubber. Silicone rubber has almost no reaction to body tissue, is odorless, and is physiologically inert, so it is suitable for use in products that come into direct contact with the human body (such as baby bottle nipples, mouthpieces, medical instruments, and medical materials). The reasons why urethane rubber is preferred is that it gives the wearer a sense of security because it is widely used, feels good against the skin, and maintains elasticity even at low temperatures. The reason why it is preferable is that it has excellent properties.

(About the hardness of the finger cot)
In the finger cots of gloves 1 to 6, the outermost finger cot has a hardness of A30° or more and A70° or less as measured by JIS K6253 durometer type A (share A). is preferred. The finger cots arranged at the outermost side of the finger cot portions are the finger cots 41a to 45a in gloves 1 and 2, the finger cots 81 to 85 in glove 3, and the replaceable finger cots 41d to 41d in gloves 4 to 6. Points to 45d.
In the finger cot parts of gloves 1 to 6, the hardness of the finger cot located at the outermost part of the finger cot part is a hardness of A30° or more and A70° or less, as measured by JIS K6253 durometer type A (share A). This allows the surface of the finger cot to easily follow and adhere to the surface of the ball, thereby preventing the ball from slipping during pitching or throwing.

In the finger cots of gloves 1 to 6, if the hardness of the outermost finger cot is greater than A70° as measured by JIS K6253 durometer type A (share A). If there is a non-slip part such as a protrusion on the surface of the finger cot, when the ball is gripped, the elastic deformation of the protrusion will be limited and will not follow the surface of the ball, resulting in a limited contact area. In addition, even if the surface of the finger cot is flat and has no anti-slip parts such as protrusions, the flat surface of the finger cot will not follow the unevenness of the surface of the ball, and the contact area will be limited, making it difficult to maintain sufficient contact area. Static friction force cannot be obtained, causing the inconvenience that the ball becomes slippery when pitching or throwing.
In addition, in the finger stalls of gloves 1 to 6, if the hardness of the outermost finger stall is smaller than A30°, when pitching or throwing a ball, the part of the fingertip that applies spin will be Because of the large deformation, it is inconvenient for accurate control similar to bare hands, and there is also the disadvantage that the finger cot itself, which is in direct contact with the ball, may partially tear and be easily damaged.
Further, for example, when the finger cots of gloves 1 to 6 contain silicone rubber, and the hardness is set to a value smaller than A30° as a value measured by JIS K6253 durometer type A (share A), for example, A20°, In order to lower the hardness of silicone rubber, compared to silicone rubber with a hardness of A30° to A70°, the material contains more silicone oil, so this may cause a bleed phenomenon where it stands out on the surface of the finger cot. According to 3.01 of the Official Baseball Rules, players are prohibited from intentionally soiling the ball, so if silicone oil gets on the ball, it would be a violation of the rules. Furthermore, when pitching or throwing a ball with a finger cot that is oozed with silicone oil, the ball slips, making it difficult to control the ball as accurately as with a bare hand.

(About the anti-slip part on the surface of the fingertips)
It is preferable that the gloves 1 to 6 include a non-slip portion on the surface of the finger cot located at the outermost side of the finger cot. It is preferable that the protrusions 91, wrinkles, or grains are integrally molded with the finger cot. The term "integral molding" refers to the fact that the material is made of the same, continuous material that is cut out using a mold, rather than being fixed using adhesives or the like. If the protrusion 91 is not integrally molded with the finger cot, but is attached by gluing or welding, for example, if the adhesive or welding part of the protrusion 91 is defective, for example, the part where the protrusion 91 is bonded or welded is defective, the pitching, This is because there is a possibility that the ball will peel off and fall off when the ball is thrown, and the ball will not function as a slipper.

The finger cot located at the outermost side of the finger cot portions of the gloves 1 to 6 is made of a rubber elastic member, and has a large number of protrusions 91, wrinkles, roughness, etc., so that when pitching or throwing a ball, It can prevent the ball and fingertips from slipping. This prevents the ball and fingertips from slipping, allowing you to control the ball as accurately as with your bare hands.
An embodiment in which the finger cots have protrusions 91 will be described using only the finger cots 41a to 45a of the glove 1. The finger cots 41a to 45a of the glove 2 are the same as the finger cots 41a to 45a of the glove 1, and the same protrusion 91 is also applied to the finger cots 81 to 85 and the finger cots 41d to 45d of the gloves 3 to 6. be done. Therefore, the explanation of the protrusions of the finger cots 81 to 85 and the finger cots 41d to 45d of the gloves 3 to 6 will be omitted.
1 to 18 of gloves 1 to 6 are diagrams in which the finger cots are provided with protrusions, and diagrams in which the finger cots are provided with wrinkles or roughness are omitted.

When the finger cots 41a to 45a of the glove 1 have protrusions 91 to prevent slipping, the shape of the protrusions is preferably a pyramidal shape such as a square pyramid or a cone, and the density of the protrusions is, for example, 80 per square centimeter. Preferably, the number is 150 or less, the height of the pyramid is about 100 μm to 500 μm, and the pyramids are regularly arranged at a substantially uniform height. If the anti-slip is not a protruding structure but has many wrinkles or grains, the depth of the cuts in the wrinkles or grains is preferably about 100 μm to 500 μm.

(About the thickness of the finger cot and the ventilation holes)
Finger cots 41a to 45a of glove 1 in FIG. 1 and glove 2 in FIG. 6, lining finger cots 41b to 45b of glove 2 in FIG. 6 and glove 5 in FIG. 12, glove 4 in FIG. 10 and glove 5 in FIG. 12 The thickness of the finger cot base parts 41c to 45c and the replaceable finger cots 41d to 45d of the glove 4 in FIG. 10, the glove 5 in FIG. 12, and the glove 6 in FIG. It is preferable that each of the wall thicknesses excluding the thickness is 100 μm or more and 1000 μm (1 mm) or less.
By making the thickness of the finger cot described above 100 μm or more, excluding the thickness of anti-slip parts such as protrusions, wrinkles, and roughness, it is possible to prevent the impact of spinning and pushing the ball with the fingertips when pitching or throwing a ball. The finger cot can withstand repeated use and maintain mechanical strength. In addition, by setting the thickness of the finger cots described above to 1000 μm (1 mm) or less, excluding the thickness of the anti-slip parts such as protrusions, wrinkles, and roughness, gloves 1, gloves 2, gloves 4, When the wearer of the glove 5 pitches or throws a ball, he or she can pitch or throw the ball with a feeling similar to that of a bare hand.

Finger cots 41a to 45a of glove 1 in FIG. 1 and glove 2 in FIG. 6, lining finger cots 41b to 45b of glove 2 in FIG. 6 and glove 5 in FIG. 12, glove 4 in FIG. 10 and glove 5 in FIG. 12 The thickness of the finger cot base parts 41c to 45c and the replaceable finger cots 41d to 45d of the glove 4 in FIG. 10, the glove 5 in FIG. 12, and the glove 6 in FIG. It is sufficient that the wall thickness excluding the thickness is 100 μm or more, but preferably 200 μm or more, and more preferably 300 μm or more. By setting the lower limit value as described above, the finger cot can repeatedly withstand the impact of spinning and pushing the ball with the fingertip during pitching or throwing, and the finger cot described above can maintain mechanical strength.
In addition, the finger cot described above may have a wall thickness of 1000 μm (1 mm) or less, excluding the thickness of the anti-slip parts such as protrusions, wrinkles, and roughness, but preferably 800 μm or less, and 700 μm or less. The thickness is more preferably 600 μm or less. By setting the upper limit as described above, the wearer of the glove using the finger cot described above can pitch or throw a ball with a feeling more similar to that of a bare hand when pitching or throwing a ball.

The finger cots 81 to 85 of the glove 3 in FIG. 8 and the finger cot base parts 81a to 85a of the glove 6 in FIG. It is preferable that the thickness is greater than or equal to 2000 μm (2 mm) or less.
By setting the thickness of the finger cot described above to be 200 μm or more, excluding the thickness of anti-slip parts such as protrusions, wrinkles, and roughness, it can withstand the impact of spinning and pushing the ball with the fingertips when pitching or throwing a ball. The finger cot can withstand repeated use and maintain mechanical strength. Further, by setting the thickness to 2000 μm (2 mm) or less, the wearer of the gloves 3 and 6 can pitch or throw a ball with a feeling similar to that of a bare hand when pitching or throwing a ball.
Note that for all types of finger cots in gloves 1 to 6, the wall thickness excluding the thickness of anti-slip parts such as protrusions, wrinkles, and roughness does not need to be uniform in all parts; for example, from the fingertip to the By making the abdomen or ventral side up to one joint thicker than the rest, the fingertips can be better protected from injury.

It is preferable that the finger cots of the fingers of gloves 1 to 6 have 1 to 3 through holes with a diameter of 2 mm or less evenly spaced per square centimeter, but the abdomen from the tip of the finger to the first joint preferably has Preferably, no through holes are formed. Note that the above-mentioned through hole means a through hole that simultaneously penetrates the fabric 50 and the finger cot to expose the skin of the finger.
By providing a through hole in the finger cot, ventilation can be ensured and heat generated at the fingertips can be released. The reason why it is preferable not to make a through hole in the abdomen from the tip of the fingertip to the first joint is because the abdomen of the fingertip is where the force that pushes the ball is concentrated during pitching or throwing, so the mechanical strength of the finger cot is This is to maintain the
Further, it is preferable that the finger cots of the gloves 1 to 6 have one through hole such as a needle hole for air venting, for example, with a diameter of 0.1 mm or less, at the center of the tip of the fingernail. By having holes for air venting, when wearing gloves 1 to 6, the air from the fingertips can escape and the fingers can be easily brought into close contact with the tips of the finger cots. For example, the holes have a diameter of 0.1 mm or less. This prevents the mechanical strength of the fingertip from decreasing.

(About the test for hardball practice balls)
It is preferable that the outermost finger cot of the finger cots of the gloves 1 to 6 has a large number of protrusions 91, anti-slip parts such as wrinkles and roughness. A prototype glove 1 was manufactured, and a pitching test was conducted using a hardball practice ball in order to evaluate the anti-slip effect of the hardness of the finger cot made of a material having rubber elasticity. The finger cots 41a to 45a of the prototype glove 1 are made of silicone rubber and have a length between the first joint and the second joint, and the hardness of the silicone rubber of the finger cots 41a to 45a is determined by JIS K6253 durometer type A ( We prepared four types of values measured by shear A): (a) A30°, (b) A50°, (c) A70°, and (d) A90°. The thickness of the finger cots 41a to 45a excluding the thickness of the protrusion 91 is 400 μm, and the finger cots 41a to 45a are fixed to the knitted fabric 50 using adhesive, and A non-slip member 100 made of silicone rubber was arranged on the back surface of the ventral side to prevent the fingers and the fabric 50 from slipping. The protrusions 91 had a conical shape, the base diameter of the cone was about 800 μm, the height was about 300 μm, and the density of the protrusions 91 was 140±5 pieces per square centimeter. The fabric 10 and fabric 20 in the center of the prototype glove body are the same knitted fabric as the fabric 50, and the fabric 10, fabric 20, and fabric 50 are continuous, and the prototype glove body has arms, and the arms have hook-and-loop fasteners. The glove itself can be fixed to the wrist. In addition, a number of silicone rubber protrusions are placed on the ventral side of the fingers and the palm side of the central part of the hand, which are in contact with the ball, to make it easier to grip the ball.

In the test, pitching was performed by five university students (170 cm to 185 cm tall) from a hardball baseball club. He threw 10 fastballs from the mound to the catcher in the catcher's box (distance 18.44 meters) with almost all his might. As a result, all 5 people answered that there was no slippage between the fingers and the ball in (A) to (C) above, and there was no problem with control, and in (D) above, all 5 people said that there was a feeling of slippage and it was difficult to control. The two observers who responded and observed the test also observed that in (a) to (c) above, the ball was well controlled, and in (d) above, the ball was not well controlled, such as the ball passing high. It was observed that there was some variation.

The test results show an example in which the finger cot and the protrusion 91 are made of silicone rubber, but the protrusion 91 has rubber elasticity, hardness within an appropriate range, and the shape and dimensions of the protrusion We have demonstrated that if the protrusions bite into the leather surface of a hard-ball practice ball, and the ball and finger cots do not slip, we will now consider the mechanism by which the protrusions bite into the leather surface of a hard-ball practice ball. . Figures 21 and 22 are enlarged photographs of an unused hardball practice ball that was arbitrarily selected and an arbitrary part thereof photographed. Hardball balls are manufactured through processing processes such as tanning cowhide, and the skin has small holes and grooves that are irregular because it is made of natural leather, as shown in Figure 21. 22 shows. When the protrusion 91 having rubber elasticity is pressed against this hole or groove, the protrusion deforms elastically and follows the complicated shape of the hole or groove on the surface of the ball, increasing the contact area and It is thought that there are places where the tip of the protrusion 91 digs into the hole or groove, which creates an effect similar to that of a wedge being caught, and that these collectively create a static friction force that prevents the ball and the fingertip from slipping. .
The protrusions 91 follow the shape of the hole or groove of the ball, deform elastically, increase the contact area, etc., and the necessary static friction force is generated with the hardness of (a) to (c) above. It is assumed that in (d) above, the protrusion was hard and could not follow the shape of the holes and grooves on the surface of the ball, and the elastic deformation was insufficient, the contact area was limited, and the static friction force was insufficient. be done.
The difference between a hardball practice ball and a hardball match ball used in games is that the cowhide surface of the ball is different, and the parts of the leather used are different. The match balls are made from cow back skin, which has fewer scratches on the skin, and the practice balls are made from cow belly skin, but it is thought that there is not a big difference between practice balls and match balls in terms of the unevenness of the epidermis. It is thought that the test results for hard-ball practice balls also apply to hard-ball match balls.

(About testing on softball baseball balls)
Regarding soft-ball baseball balls, the effect of protrusions due to differences in the hardness of the finger cots was evaluated by conducting pitching tests with the finger cots listed in (a) to (e) above using the same prototype glove 1 used for hard-ball practice balls. did. There are two types of softball balls: J (for elementary school students) and M (for junior high school students and the general public), but since they are made of the same rubber and have the same pattern on the surface, the M official ball is used. only was used in the test.

For the softball baseball team, five university students (170cm to 185cm tall) from the softball club pitched 10 fastballs from the mound to the catcher in the catcher's box (distance 18.44m) using almost all of their strength. Before the test, calcium carbonate particles adhering to the ball surface were washed away with water and thoroughly dried. As for the results (a) to (d) above, all five players answered that the ball was slippery and the control varied, and two observers also observed variations in control. Therefore, when the surfaces of the silicone rubber finger cots 41a to 45a without protrusions 91 are flat, the values measured by JIS K6253 durometer type A (share A) are (F) A30°, (G) A50°, ( Prototype gloves 1 with four types of finger cots, h) A70° and (k) A90°, were prepared and a pitching test was conducted. As a result, all five respondents answered that there was no slippage between the fingers and the ball in (k) to (k) above, and there was no problem with control, and in (ke) above, all five answered that there was a feeling of slippage and control was inconsistent. The two observers who responded and observed the test also observed that in (f) to (h) above, the ball was well controlled, and in (g) above, the ball was not well controlled, such as the ball passing high. It was observed that there was some variation.

Analyzing the test results of softball baseball balls, it was found that the unevenness on the rubber surface of softball baseball balls was finely textured, and the protrusion 91 used in the test was able to bite into the surface of the ball regardless of the hardness of the silicone rubber. The reason for the slippage is presumed to be that the contact area was limited. If the protrusions are eliminated and the surfaces of the finger cots 41a to 45a are made flat, in cases (f) to (h) above, the surfaces of the finger cots 41a to 45a will be in better contact with the surface of the softball baseball, and the surface of the finger cots 41a to 45a will be in better contact with the ball. It is presumed that the contact area of the ball was increased and the necessary static friction force was generated. It is presumed that the contact area was limited and the static friction force was insufficient.

Next, the softball baseball was evaluated by conducting a test using a silicone rubber finger cot with wrinkles and grains. The same prototype glove 1 as used for hardball practice balls is prepared, but the finger cots 41a to 45a have wrinkles and texture, and the thickness of the finger cots 41a to 45a is the same as the thickness of the wrinkled and textured parts. The thickness excluding the thickness was 400 μm. The hardness of the silicone rubber of the finger cots is A30° as measured by JIS K6253 durometer type A (share A), and the depth of the wrinkles is 200 μm as the non-slip part of the finger cots 41a to 45a. Two types were prepared: one with a large number of wrinkles on the epidermis of approximately ~500 μm, and one with a large number of grains with a cutting depth of approximately 100 μm to 200 μm. In the test, the five university students from the aforementioned softball baseball club were asked to throw 10 fastballs from the mound to the catcher in the catcher's box (distance: 18.44 meters) with almost all of their strength. As a result, in both (sa) and (c) above, all five people answered that the ball did not slip and there were no problems with control, and two observers also observed that the ball was being controlled. Observed. It is speculated that if the finger cot, which is a member with rubber elasticity, had an appropriate hardness, the wrinkles and roughness would come into close contact with the rubber skin of the ball, increasing the contact area with the ball and generating the necessary static friction force. be done.

If the competition is softball baseball, the test results show that for both types of softball, J (for elementary school students) and M (for junior high school students and the general public), gloves 1 to 6 should be placed on the outermost part of the finger cot. It is preferable that the surface (front) of the finger cot to be placed has wrinkles or roughness instead of a protruding anti-slip part, or it is preferable that the surface (front) of the finger cot has no anti-slip part and The noodles may be flat and smooth.

(Test for softball)
For softball balls, the effect of protrusions depending on the hardness of the finger cots was evaluated by conducting pitching tests with the finger cots described in (a) to (d) above using the same prototype glove 1 used for hardball practice balls. . There are three types of softballs: No. 1 (for lower grades of elementary school students), No. 2 (for all grades of elementary school students), and No. 3 (for general use). There are also leather ones (cowskin is used) used by university students and business groups. Japan is the only country that uses rubber softballs as official balls, and leather ones are used in international tournaments and overseas. The surfaces of the three types of rubber balls have protrusions with different roughness, so four types were used in the test: official rubber balls No. 1 to No. 3 and official leather balls No. 3. .
For softball, prototype gloves 1 with the finger cots described in (a) to (e) above were given to five university students (160cm to 175cm tall) in the softball club from the mound to the catcher's box (distance: 13.11cm for girls). He threw almost all of his strength to the catcher (14.02 meters tall for men) and pitched 10 pitches, including only fastballs. As a result, for all four types of tests used in the test, all five people answered that the ball did not slip in (a) to (c) above, and there were no problems with control, and two observers also said that the ball did not slide. I observed how it was controlled. However, in (d) above, all five respondents said that the ball tends to slip and there are variations in control, such as the ball passing low, and two observers also observed variations in control.

Analyzing the test results for softballs, for three types of balls with rubber skins (No. 1 to No. 3 balls), if the protrusion 91, which is a member with rubber elasticity, has an appropriate hardness, the surface of the ball will improve. When the protrusions of the rubber and the protrusions 91 of the finger cot come into contact, the protrusions 91 enter the valleys of the protrusions of the ball, and both the protrusions of the ball and the protrusions 91 elastically deform and come into close contact with each other. It is presumed that this increases the area and generates the necessary static friction force.As for the No. 3 leather official ball, the skin is made of cowhide, so the same mechanism as the hard practice ball is used to create a rubber-elastic member. It is presumed that if the protrusion 91 had an appropriate hardness, the contact area would increase and the necessary static friction force would be generated.

(About the durability test of the anti-slip part of the finger cot)
Next, the durability of the finger cot protrusion 91 is tested and evaluated using the same prototype glove 1 used for the hardball practice ball. Using a hardball practice ball and the finger cots described in (a) to (c) above, three university students A, B, and C from the hardball baseball team were asked to play (a) for A and (i) for B. ), C had the player use the finger sack glove 1 from (c) and pitch 100 straight balls from the mound to the catcher in the catcher's box (distance 18.44 meters). As a result, after pitching 100 pitches, the protrusions on the abdomen at the fingertips of the second and third fingers were particularly worn, and the height of the protrusions 91 was worn down, or the tips of the protrusions 91 were torn off. It was observed that protrusions were lowered from the original height of about 300 μm to about 50 to 150 μm. The degree of abrasion was the highest in (a), the least in (c), and somewhere in between in (b).

The cause of the wear is presumed to be due to friction with the complex shape of the leather surface of the hardball, as shown in Figures 21 and 22. It is presumed that the cause was that there was a seam made of thread, and the tip of the protrusion got caught in the seam, causing shear stress. However, all three university students from the hardball baseball club who conducted the pitching test answered that even after throwing 100 pitches, the ball did not slip between their fingertips. If you look at the surface of the protrusion, which has been worn away or had its tip ripped off by pitching, you will find that it is moderately rough, and the contact area is maintained by the rough part coming into close contact with the holes and grooves on the surface of the ball. The reason for this is thought to be that the necessary static friction force was maintained.

Let us further consider the case where a protrusion is provided on the finger cot. In order to create a static friction force that prevents fingers and the ball from slipping without damaging the surface of the ball, the protrusions of the finger cot, which has rubber elasticity, need to wear out and wear down. It is thought that this reduction creates a static friction force that prevents fingers and the ball from slipping.If we consider how durable the finger cot protrusions are, it is likely that It cannot be determined uniformly because it depends on the material and hardness of the sack, but for example, the finger sacks for the second and third fingers, which apply strong spin to the ball, are made of silicone rubber, and the hardness is JIS. K6253 In the case of A30° to A70° as measured by durometer type A (share A), the protrusion is thought to deteriorate after approximately 100 to 200 pitches, and should be replaced every 100 to 200 pitches. It seems recommended to do so. In the case of gloves 1 to 3, when the finger cot protrusions wear out, the gloves must be discarded, but in the case of gloves 4 to 6, the replaceable finger cots 41d to 45d are worn out. The glove itself can be reused by replacing only the finger cot with a new finger cot.

(About the combination of finger cot hardness for gloves 1 to 6)
The purpose of the finger cots on the fingertips of gloves 1 to 6 is to protect the fingertips and finger pads from injuries such as blood blisters and cracked nails, and to prevent the ball and fingertips from slipping when pitching or throwing a ball. That's true.
In the case of Gloves 2 and Gloves 4 to 6, the finger cot is made up of multiple finger cots, so the outermost part of the finger cot is designed to protect the finger tip from injury and prevent the ball and finger tip from slipping. It is preferable that the hardness of the fingerstalls that are not placed on the outermost side is made harder than the hardness of the fingerstalls that are arranged. Regarding the hardness of the finger cot that has a non-slip part such as the protrusion 91 of the finger cot that comes into contact with the ball, if you choose a hardness that bites into the ball well, it will create the necessary static friction force to prevent the ball and fingertip from slipping. The fingertips can be further protected from injury by making the finger cots that are not disposed on the outermost side have a harder hardness than the finger cots that are disposed on the outermost side.
For example, in the case of glove 2, it is preferable that the hardness of finger cots 41b to 45b is harder than that of finger cots 41a to 45a, and in the case of glove 4, the hardness of finger cots 41b to 45b is preferably harder than that of finger cots 41d to 45d. It is preferable that the hardness of the base parts 41c to 45c is hard, and in the glove 5, the hardness of the finger cot base parts 41c to 45c and the finger cots 41b to 45b is preferably made harder than the hardness of the finger cots 41d to 45d. In the glove 6, it is preferable that the finger cot base portions 81a to 85a have a harder hardness than the finger cots 41d to 45d.
Specifically, in the case of Glove 2 and Gloves 4 to 6, the hardness of the finger cots placed on the outermost side is set to A30°, A50°, etc., and the hardness of the finger cots placed on the outermost side is, for example, A30°, A50°, etc. , for example, A70°. Note that hardness values such as A30° are values measured by JIS K6253 durometer type A (share A).

In the case of Gloves 1 and 3, the finger cots are composed of a single finger cot, so the dip molding method is adopted as the production method for the finger cots 41a to 45a of Glove 1 and the finger cots 81 to 85 of Glove 3. However, when forming by dipping twice, it is preferable that the hardness of the back side, which is the side that comes into contact with fingers, is harder than the hardness of the front side, which is the side that comes into contact with the ball. If you choose a finger cot that has a non-slip part such as a protrusion 91 on the surface that comes into contact with the ball and has a hardness that bites into the ball well, it will reduce the necessary static friction to prevent the ball and fingertips from slipping. By making the back side harder than the front side, the fingertips can be further protected from injury.
For example, for the finger cots 41a to 45a of the glove 1 and the finger cots 81 to 85 of the glove 3, the surface side has a hardness of A30°, A50°, etc., and the protrusions 91, wrinkles, etc. If you make half of the wall thickness excluding the thickness of the anti-slip part such as grain, and then make the remaining wall thickness for the back side with a hardness of A70°, for example, the surface that will be in contact with the ball to be used (Omotemen) has a non-slip part such as the protrusion 91 that bites into the ball well and generates the necessary static friction force to prevent the ball and fingertips from slipping, and the hardness of the back side is the same as the surface (Omotemen). (noodles) are harder, so they can better protect your fingertips from injury. The hardness value is a value measured by JIS K6253 durometer type A (share A).
Regarding the production method of the finger cots 41a to 45a of the glove 1 and the finger cots 81 to 85 of the glove 3, the method of producing the finger cots 41a to 45a of the glove 3 is made by a method that does not involve double dipping and molding using the dip molding method. A method of increasing the hardness of the back side may be used. For example, the front side and the back side are produced and prepared separately using dip molding or a 3D printer, and the hardness of the prepared front side and back side is the same as that of the front side. For example, the back side is made harder than the front side, and the front side and back side are joined by adhesive or welding.

If the production method for the finger cot placed at the outermost part of the finger cot is, for example, by dipping and molding multiple times by dip molding, the surface (front) of the finger cot placed at the outermost part of the finger cot will be It is preferable that the thick part on the noodle side and the next thick part be molded in different colors. By using different colors for the thick part on the front side and the next thick part, the anti-slip parts such as the protrusions 91 will wear out, and the surface (front side) will be further damaged. If the thick part on the side is worn out, the color of the next thick part will be observed with the naked eye.For example, if the finger cots 41d to 45d are replaceable, it is a good idea to replace them with new finger cots. It can be done. The finger cots disposed at the outermost side of the finger cot portions are the finger cots 41a to 45a in gloves 1 and 2, the finger cots 81 to 85 in glove 3, and the replaceable finger cots 41d in gloves 4 to 6. - Points to 45d.

(About the anti-slip part on the back of the fingertips)
The finger fabric 50 of the glove 2 in FIG. 6 and the glove 5 in FIG. It is preferable that the contact surfaces have a large number of protrusions 92 or anti-slip portions such as grooves, wrinkles, and rough texture. The finger cots 41b to 45b have a large number of protrusions 92 or grooves, wrinkles, grains, etc. to create a gap for sweat generated from the ventral side of the fingers to escape, and when pitching or throwing a ball, the fingers and finger cots are formed. 41b to 45b can be directly prevented from slipping, and since the fingers and finger cots 41b to 45b do not slip, blood blisters can form on the fingertips and finger pads, the skin of the bloody blisters can tear, the skin of the fingers can peel off, and the fingernails can be prevented from slipping. It is possible to further enhance the effect of preventing injuries such as cracking of the nail or nail digging into the finger (nail digging into the side edge of the nail plate).

It is preferable that the finger cots 81 to 85 of the glove 3 in FIG. 8 and the finger cots 81a to 85a of the glove 6 in FIG. 14 have a large number of protrusions 92, grooves, wrinkles, roughness, etc. on the surfaces that come into contact with the fingers. The finger cots 81 to 85 and the finger cots 81a to 85a have a large number of protrusions 92, grooves, wrinkles, grains, etc. on the surfaces that come into contact with the fingers, thereby creating gaps that allow sweat generated from the finger pads to escape. When pitching or throwing a ball, the fingers and finger cots 81 to 85 and the fingers and finger cots 81a to 85a can be directly prevented from slipping, and the fingers and finger cots 81 to 85 and the fingers and finger cots 81a to 85a do not slip. The effect of preventing injuries such as blood blisters forming on the fingertips and finger pads, tearing of the skin of the blood blisters, peeling of the skin of the fingers, cracking of the nails, and nails digging into the fingers (nails digging into the side edges of the nail plate). can be further increased.

When the finger cots 41b to 45b of the gloves 2 and 5, the finger cots 81 to 85 of the glove 3, and the finger cots 81a to 85a of the glove 6 have a large number of protrusions 92 on the surfaces that contact the fingers, the protrusions 92 are For example, it is preferable that the protrusions 92 have a conical shape, the base diameter of the cone is about 800 μm, the height is about 300 μm, and the density of the protrusions 92 is 140 pieces per square centimeter. When having many wrinkles, the depth of the wrinkles is preferably about 200 μm to 500 μm, and when having grain, the depth of the cut of the grain is preferably about 100 μm to 200 μm. It is said that the depth of finger prints is about 100 to 200 μm, and the dimensions related to the protrusions 92, wrinkles, and grit described above create gaps for sweat to escape, and at the same time bite well into the fingers to prevent slipping. You can expect good results.

(About the size of the finger cot)
The shape of a person's fingertip (i.e., the area from the first joint of the finger to the tip of the finger) has characteristics depending on the person, but the finger cots used in gloves 1 to 6 are based on the shape of the wearer's fingertip (i.e., It is preferable that the finger cot be appropriately matched to the length, thickness, rounded shape, etc.).
If the finger cots do not match the shape of the fingertips of the wearer of gloves 1 to 6 and the wearer's fingertips are smaller, or if the shape does not match and there is a partial gap, the finger cots may not match the shape of the fingertips of the wearer of gloves 1 to 6. The sack and the abdomen of the fingertip do not come into close contact, and the fabric 50 in direct contact with the finger or the finger sack rubs against the abdomen of the finger, making it easy to cause injuries such as blood blisters and making it difficult to control the ball. In addition, if the fingertip is larger than the finger cot, the finger cot will stretch when worn, but the elastic stress of the rubber will be applied to the finger tip by the amount of the finger cot stretching, causing numbness or discomfort in the finger tip such as obstructing blood flow. This is inconvenient because it makes it easier to feel pleasure.
In order not to injure the fingertips or cause numbness or discomfort, the finger cots of gloves 1 to 6 should be approximately the same size as the fingertips, or should fit comfortably and have an appropriate amount of tension. In other words, it is preferable that the fingertip be the same size as the finger cot or only slightly larger, and the elastic stress exerted by the finger cot on the finger tip can be measured by using an air pack sensor type I, etc. It is preferable to suppress the obtained value to about 0.04 to 0.10 N/cm2 or less.

(About the front side of the finger cot base and the back side of the replaceable finger cot)
The surfaces of the finger cot bases 41c to 45c of the gloves 4 in FIG. 10 and the gloves 5 in FIG. 12 (front surface), and the surfaces of the finger cot bases 81a to 85a of the glove 6 in FIG. It is preferable that the back surfaces of the replaceable finger cots 41d to 45d have a smooth and flat surface without protrusions, irregularities, grooves, wrinkles, roughness, etc.
The surfaces of the finger cot bases 41c to 45c of the gloves 4 in FIG. 10 and the gloves 5 in FIG. 12 (front surface), and the surfaces of the finger cot bases 81a to 85a of the glove 6 in FIG. By making the back surfaces of the replaceable finger cots 41d to 45d smooth and flat, the degree of adhesion when the replaceable finger cots 41d to 45d are attached to the finger cot base increases, and they can be replaced when pitching or throwing a ball. It is possible to prevent the finger cots 41d to 45d from shifting from the base of the finger cots. Although the surface of a rubber-elastic member may appear smooth and flat, it actually has microscopic unevenness, and when these microscopically uneven surfaces come together, the unevenness follows each other and they stick together. It is thought that because of this, the true contact area becomes extremely large, the coefficient of static friction increases, and the static frictional force increases.

If the finger cot base parts 41c to 45c of the gloves 4 and 5, the finger cot base parts 81a to 85a of the glove 6, and the replaceable finger cots 41d to 45d are products using molds, the finger cot base parts The surface condition of the front surface (front surface) and the back surface of the replaceable finger cot depends on the surface treatment of the mold for that part, and the surface treatment may be mirror finishing (for example, polishing with #3000 to #5000) or It is ideal to use extremely fine grain (for example, polishing with #1000 to #2000), but polishing the mold is not practical because it increases the cost of the mold (in other words, the production cost of the finger cot increases). For example, it is preferable that the surface treatment is polishing with a fineness (#800) or less, such as #400 to #600.

(About the test regarding the close contact between the finger cot base and the replaceable finger cot)
The finger cot base parts 41c to 45c and the replaceable finger cots 41d to 45d of the glove 4 shown in FIG. 10 were prototyped using (T) a mold manually polished with #400, and (H) dip molding method. We prepared two types of prototype gloves, one made by the above-mentioned baseball team, and conducted a pitching test by having five university students from the above-mentioned hardball baseball club wear the prototype gloves 4, to see if the replaceable finger cots would not shift from the finger cot base. was evaluated. In the dip molding method (H) above, the surfaces that do not come into contact with the male mold are the surfaces of the base portions 41c to 45c and the back surfaces of the replaceable finger cots 41d to 45d.
The replaceable finger cots 41d to 45d and the finger cot base parts 41c to 45c of the prototype glove 4 are made of silicone rubber, have a length from the fingertip to the first joint, and have a hardness of JIS K6253 durometer type A (Share The thickness of the replaceable finger cots 41d to 45d and the finger cot base parts 81a to 85a, excluding the thickness of the protrusion 91, is 400 μm. The finger cot base parts 41c to 45c are fixed to the fabric 50, which is a knitted fabric, using an adhesive, and a silicone rubber anti-slip member 100 is placed on the back side of the ventral side of the fingers of the fabric 50 to prevent the fingers and the fabric 50 from slipping. I made it. The protrusions 91 of the replaceable finger cots 41d to 45d are conical, with a base diameter of about 800 μm and a height of about 300 μm, and the density of the protrusions 91 is 140 ± 5 pieces per square centimeter. did. The fabric 10 and fabric 20 in the center of the glove body are the same knitted fabric as the fabric 50, and the fabric 10, fabric 20, and fabric 50 are continuous, and the glove body has an arm portion, and the arm portion is provided with a hook-and-loop fastener. This allows the glove body to be fixed to the wrist. In addition, a number of silicone rubber protrusions are placed on the ventral side of the fingers and the palm side of the central part of the hand, which are in contact with the ball, to make it easier to grip the ball.

A pitching test using prototype gloves 4 was conducted on five university students from the above-mentioned hardball baseball club. He threw 10 fastballs from the mound to the catcher in the catcher's box (distance 18.44 meters) with almost all his might. As a result, in both (T) and (H), no phenomenon in which the replaceable finger cots 41d to 45d were peeled off or shifted from the finger cot base portions 41c to 45c was observed in all spheres. The results show that, for example, in a finger cot manufactured using a hand-polished mold with #400 or a finger cot manufactured by dip molding, the replaceable finger cot and finger cot base are the first part from the fingertip. If the length is up to one joint, and the replaceable finger cot and finger cot base are in close contact, it will be evaluated as having the necessary static friction force, and it will be considered practical.

In addition, when the wearer of glove 1 considers safety measures to prevent the base part of the finger cot and the replaceable finger cot from being misaligned, for example, the length of the base part of the finger cot and the replaceable finger cot should be It is preferable to install the replaceable finger cot from the base of the finger cot to around the second joint. Also, before fitting the replaceable finger cot into the base of the finger cot, apply an anti-slip spray (mainly a rosin-containing spray that batters use on the grip of the bat), etc. It is preferable to lightly spray the base of the finger cot before fitting it.
By making the base part of the finger cot and the length of the replaceable finger cot from the fingertip to the vicinity of the second joint, the contact area is relatively increased, so that when the replaceable finger cot is pitching or throwing a ball, The phenomenon of misalignment can be further prevented. In addition, by using anti-slip spray, the base of the finger cot and the replaceable finger cot will be in close contact with each other, thereby increasing the effectiveness of preventing slippage.
In particular, regarding the second and third fingers, pitchers who throw forkballs, which are curveballs, often pinch the ball between the finger sides of their second and third fingers. It is preferable that the length of the finger cot that is replaceable with the base part of the finger cot extends from the fingertip to the vicinity of the second joint.

Even if the finger cots are manufactured using a mold finished with #400 or higher, when installing the replaceable finger cots, for example, fine sand may be present in a ballpark under dusty conditions. If it adheres, it will create a film that will inhibit the adhesion between the base of the finger cot and the replaceable finger cot, potentially weakening the degree of adhesion. If you don't have time to wash away the build-up with water or wipe it off, you can prevent it from slipping by spraying it lightly with anti-slip spray before fitting it back in.
However, the hydrocarbon solvents contained in the above-mentioned anti-slip sprays may deteriorate the materials used for the finger cots, and the compatibility of the hydrocarbon solvents contained with the materials used for the finger cots and gloves is limited. Caution must be taken. For example, if the hydrocarbon solvent contained in the anti-slip spray is acetone, if the material of the finger cot is natural rubber or silicone, it will not deteriorate easily, but if it is made of urethane rubber or nitrile rubber, it will deteriorate easily. , it is necessary to consider the material used for the finger cot.

When providing through holes for ventilation in the finger cots of gloves 4 to 6, when the replaceable finger cot is inserted into the base of the finger cot, the through hole of the replaceable finger cot will be inserted into the base of the finger cot. It is assumed that the hole may not be located at the same position as the through hole. In order to prevent this, the through hole of the replaceable finger cot may have a diameter of about 1 mm, but it is preferable that the through hole of the base of the finger cot has a diameter of about 2 mm to 3 mm. In addition, in order to prevent the position of the through hole from shifting laterally when inserting the replaceable finger cot into the base of the finger cot, gloves 4 to 6 are attached with a black marker line, for example, from the center of the tip of the nail at the base of the finger cot toward the back of the hand. You can print it out and use it as a marker. A black marker line is also printed on the back side of the replaceable finger cot (the surface that contacts the finger cot base), and by fitting it to match the marker line on the finger cot base, it is possible to prevent lateral shifting.

(Regarding the member that covers the back of the fingers of the glove)
The fabric 50 of the finger portion of the glove 1 in FIG. 1 has a member 100 or a protrusion 101 as an anti-slip member on the ventral side of the surface that contacts the fingers (ie, the back surface of the fabric). The main purpose of arranging the member 100 or the protrusion 101 on the back surface of the fabric 50 is to prevent the fabric 50 from shifting relative to the fingers. The member 100 is shown in FIG. 5 (AA' sectional view of the second finger in FIG. 1) and FIG. 19 (GG' sectional view of the second finger in FIG. 2). FIG. 3 is a schematic structural cross-sectional view in a case where the member 100 covers not only the ventral side but also the ventral side. The protrusion 101 is shown in FIG. 20 (HH' sectional view of the second finger in FIG. 4), and FIG. 20 is a schematic structural sectional view when the protrusion 101 covers not only the abdomen but also the ventral side. . Possible methods for fixing the member 100 and the protrusion 101 to the back surface of the finger material 50 include welding, adhesion, and sewing.

Because the fabric 50 of the finger portion of the glove 1 has the member 100 or the protrusion 101, even when pitching or throwing a ball with close to full force, such as an initial velocity exceeding 140 km/h, the fabric 50 of the finger portion of the glove 1 may 50 can be prevented from slipping and moving from the finger. Since the dough 50 does not shift from the fingers, the finger cot provided at the tip of the dough 50 does not shift from the fingertips, so when pitching or throwing a ball, it is possible to maintain the same precise control as when pitching with bare hands. can. In addition, when the wearer of the glove 1 receives a ball hit, pitched, thrown, etc. on the ventral side of the finger, the degree of impact is alleviated to eliminate or reduce the degree of injury that may be caused to the finger. Can be done.
Further, in the gloves 1 and 4, the member 100 or the protrusion 101 can be arranged up to the tip of the fingertip, and in the glove 1 and the glove 4, the member 100 or the protrusion 101 can be arranged up to the tip of the fingertip. By doing so, it is possible to enhance the anti-slip effect of preventing the fingertips from slipping off the fabric 50, and at the same time, it is possible to strengthen the protection of the abdomen of the fingers. However, if the wearer of Glove 1 wants to make pitching or throwing as close as possible to the sensation of throwing a ball with bare hands, the player should focus on the feeling of gripping the ball with the abdomen from the first joint of the finger to the tip of the finger. It is necessary to reduce the thickness of gloves. In that case, in the gloves 1 and 4, it is not necessary to arrange the member 100 or the protrusion 101 up to the tip of the fingertip.

First, a case where the material 50 of the finger portion of the glove 1 in FIG. 1 has the member 100 will be described. It is preferable that the shape of the member 100 is, for example, a band shape as shown in FIGS. 5 and 19, arranged in parallel with a gap, and covering a part of the ventral side.
The member 100 of the finger fabric 50 is preferably in the form of a band with a width of about 3 mm to 8 mm, and is preferably arranged in parallel with a gap of about 2 mm to 3 mm, for example. Since the member 100 has the dimensions described above, it is possible to prevent the dough 50 from slipping off the finger when pitching or throwing a ball, and the member 100 can be arranged with the gap as described above. Accordingly, the fabric 50 of the finger portion can ensure breathability, and the finger can be bent and straightened easily.

Materials constituting the member 100 of the fabric 50 in FIGS. 5 and 19 include, for example, natural rubber, synthetic natural rubber, silicone rubber, nitrile rubber, urethane rubber, EPDM, polyurethane resin, vinyl chloride resin, etc. as described above. By selecting this material, you can avoid scratching your fingers. Among these, it is preferable that the member 100 contains silicone rubber. Silicone rubber has almost no reaction to body tissues, is odorless, and is physiologically inert, so it is suitable for use in products that come in direct contact with the human body (such as baby bottle nipples, mouthpieces, medical instruments, and medical materials). The reason why it is preferable for the member 100 to include silicone rubber is that it is a material that gives a sense of security to the wearer of the glove 1 because it is widely used, has a good texture, and maintains elasticity even at low temperatures. . Since the member 100 contains silicone rubber, the member 100 has elasticity, which increases the anti-slip effect, and maintains elasticity even in low temperature environments, so it is comfortable for fingers regardless of the season. It is possible to avoid scratches, and it is difficult to prevent the fabric 50 from freely expanding and contracting in accordance with the movement of the wearer's fingers, making it easier to grasp the ball. Further, it is preferable to provide protrusions, grooves, wrinkles, roughness, etc. on the surface of the member 100 that comes into contact with fingers, as this further enhances the anti-slip effect.

The thickness of the member 100 of the fabric 50 in FIGS. 5 and 19 is preferably 100 μm or more and 800 μm or less, excluding portions such as protrusions, grooves, wrinkles, and grains. By setting the thickness of the member 100 to 800 μm or less, the wearer of the glove 1 can maintain a feeling similar to that of a bare hand, and can easily grip the ball, and by setting the thickness of the member 100 to 100 μm or more, the member 100 can It ensures mechanical strength, and also reduces the degree of impact when the finger pad is hit by a ball, pitched, thrown, etc., and eliminates or reduces the degree of injury that may occur to the finger. .

The thickness of the member 100 of the fabric 50 in FIGS. 5 and 19 may be 800 μm or less, more preferably 600 μm or less, and even more preferably 400 μm or less. By setting the upper limit of the thickness of the member 100 of the finger material 50 to the above value, the wearer of the glove 1 can maintain a feeling similar to that of a bare hand, making it easier to grip the ball. Further, the thickness of the member 100 of the fabric 50 in FIGS. 5 and 19 may be 100 μm or more, but is more preferably 150 μm or more, and even more preferably 200 μm or more. By setting the lower limit of the thickness of the member 100 of the finger fabric 50 as above, the member 100 ensures mechanical strength and also reduces the degree of impact when the finger pad receives a batted ball, a pitched ball, a thrown ball, etc. Softening can eliminate or reduce the degree of injury that the finger may sustain.

Next, a case where the fabric 50 of the finger portion of the glove 1 in FIG. 1 has a protrusion 101 will be described. The protrusions 101 disposed on the fabric 50 in FIGS. 5 and 19 preferably have a conical shape such as a square pyramid or a cone, and the shape and dimensions of the base of the cone are 1 mm or more and 2 mm on one side. The following rectangles or shapes with rounded corners of rectangles, polygons or shapes with rounded corners of polygons, circles, ovals, and combinations of curves and straight lines with sides of 1 mm or more and 2 mm or less and an area equivalent to a rectangle. The shape is preferable, and the height is preferably about 0.5 mm to 2 mm, and the protrusions are preferably arranged regularly at intervals of about 1 mm to 1.5 mm, and the protrusions of approximately the same shape and size are preferably arranged. By setting the shape and height of the protrusions 101 as described above, and by making the protrusions 101 regularly arranged at intervals of about 1 mm to 1.5 mm and having approximately the same shape and dimensions, the fabric 50 is breathable. Since the pressure can be applied evenly to the entire contact surface with the fingers, the anti-slip effect can be achieved evenly over the entire arrangement of the protrusions 101, and the wearer of the glove 1 can Since the pressure is applied evenly to the entire contact surface of the fingers, a comfortable fit can be obtained.

The materials constituting the protrusions 101 of the fabric 50 in FIGS. 5 and 19 include, for example, natural rubber, synthetic natural rubber, silicone rubber, nitrile rubber, urethane rubber, EPDM, polyurethane resin, vinyl chloride resin, etc. By choosing the materials described, it is possible to avoid scratching the fingers. Among these, it is preferable that the protrusion 101 contains silicone rubber. Silicone rubber has almost no reaction to body tissues, is odorless, and is physiologically inert, so it is suitable for use in products that come in direct contact with the human body (such as baby bottle nipples, mouthpieces, medical instruments, and medical materials). The reason why it is preferable for the protrusion 101 to include silicone rubber is because it is a material that gives a sense of security to the wearer of the glove 1 because it is widely used, has a good texture, and maintains elasticity even at low temperatures. be. Since the protrusion 101 contains silicone rubber, the protrusion 101 has elasticity, which increases the anti-slip effect, and maintains elasticity even in low temperature environments, so it can be used regardless of the season. It is possible to avoid damaging the fingers, and it is difficult to prevent the cloth 50 from freely expanding and contracting according to the movement of the wearer's fingers, making it easier to grasp the ball.

(Regarding testing of the material that covers the back of the fingers of gloves)
The fabric 50 of the finger part of the glove 1 in FIG. However, the effect of the member 100 or the protrusion 101, including other methods, will be tested and comparatively evaluated.
On the surface of the fabric 50 of the finger portion of the glove 1 that contacts the fingers (that is, the back side of the fabric), on the ventral side of the part that does not overlap with the finger cots 41a to 45a, a member 100 is placed in the form of a band with a width of 4 mm and a thickness. 400 μm silicone rubber is arranged in parallel at 3 mm intervals. (d) A silicone rubber cone is selected as the protrusion 101, and the diameter of the base of the cone is 1.6 mm, the height is 0.6 mm, and the height is 0.8 mm. The fabric 50, which is a knitted fabric that is arranged regularly at intervals, is prototyped as a knitted fabric of spandex, which is a polyurethane fiber that is said to have a relatively excellent coefficient of friction, and the non-slip member is not arranged. A certain fabric 50 was prototyped using NanoFront (manufactured by Teijin Ltd.), which is made of ultra-fine polyester nanofiber that is said to have a non-slip effect on fingers, and four types were prototyped: one without any anti-slip material. and evaluated.
The finger cots 41a to 45a of the prototype glove 1 are made of silicone rubber, and the hardness of the silicone rubber of the finger cots 41a to 45a is measured by JIS K6253 durometer type A (share A) to prevent the balls and finger cots from slipping. A30° was prepared as the value. The wall thickness of the finger cots 41a to 45a excluding the thickness of the protrusion 91 is 400 μm, the finger cots 41a to 45a are fixed to the knitted fabric 50 using adhesive, and the protrusion 91 is made of a conical shape. The shape of the cone was approximately 800 μm in base diameter and approximately 300 μm in height, and the density of finger pad protrusions 91 was 140 ± 5 per square centimeter. Fabric 10 and fabric 20 in the central part of the glove body are knitted fabrics, fabric 10, fabric 20 and fabric 50 are continuous, and (N) and (N) are made continuous by sewing. The glove body has an arm section, and the arm section is equipped with a hook-and-loop fastener, allowing the glove body to be fixed to the wrist. In addition, a number of silicone rubber protrusions are placed on the ventral side of the fingers and the palm side of the central part of the hand, which are in contact with the ball, to make it easier to grip the ball.

The test was conducted by five university students (170 to 185 cm tall) from a hardball baseball club, using hardball practice balls to pitch. He threw 10 fastballs from the mound to the catcher in the catcher's box (distance 18.44 meters) with almost all his might. As a result, all five respondents answered that (N) and (D) above, due to the effect of the anti-slip member, the fabric 50 does not shift relative to the fingers, allowing controlled pitching. (N) and (N) suggest that when you grip the ball, your fingers and the inside of the fabric 50 slip, and you cannot feel the anti-slip effect, making it difficult to control, and it is difficult to throw with all your might. All five respondents answered that they felt stressed before the pitching test, and that if the abdomen of the finger past the first joint and the fabric 50 slipped, it would be difficult to release the ball violently from the fingertip. Considering the risk of blood blisters, the pitching test was completed with one pitch for all five players. In the one-pitch pitching test, all five players were unable to throw with all their might or control accurately.

The test results show that in order to have accurate control like with bare hands, it is necessary for the fabric 50 to not slip or shift against the fingers, and that the anti-slip member 100 or the protrusion 101 is effective. For example, if a fabric that is said to have an anti-slip effect on fingers is used for the fabric 50, the fingers and the fabric will shift because no anti-slip members or protrusions are provided, which is actually inconvenient. It is evaluated that there is.

(Regarding the member that covers the ventral side of the fingers of the glove)
The fabric 50 of the finger part of the glove 1 in FIG. 1 has a member 60 covering the abdomen or ventral side on the surface of the fabric (front) that does not overlap with the finger cots 41a to 45a, or a member 60 as shown in FIG. It is preferable to have a protrusion 11. The purpose of the member 60 or the protrusion 11 is to provide an anti-slip effect when the ball is gripped, and to reduce the degree of impact when the ball is hit, pitched, thrown, etc. to the fingers, thereby reducing the possibility of the fingers being hit. The goal is to eliminate certain injuries or reduce the severity of injuries. The member 60 is shown in FIG. 5 (AA' sectional view of the second finger in FIG. 1) and FIG. 19 (GG' sectional view of the second finger in FIG. 2), but in FIG. FIG. 3 is a schematic structural cross-sectional view when the member 100 covers the front side. The protrusion 11 is shown in FIG. 20 (HH' sectional view of the second finger in FIG. 4), and FIG. 20 is a schematic structural sectional view when the protrusion 11 covers not only the abdomen but also the ventral side. . Possible methods for fixing the member 60 and the protrusion 11 to the finger fabric 50 include welding, adhesion, and sewing.

Since the protrusion 11 has already been explained, the case where the fabric 50 of the finger portion of the glove 1 in FIG. 1 has the member 60 will be explained. It is preferable that the shape of the member 60 is, for example, a band shape as shown in FIGS. 5 and 19, arranged in parallel with a gap, and covering the abdomen or ventral side.
The member 60 of the finger fabric 50 is preferably in the form of a band with a width of about 3 mm to 8 mm, and is preferably arranged in parallel with a gap of about 2 mm to 3 mm, for example, and the member on the back side It is preferable to have the same shape and the same position as 100. Since the member 100 has the dimensions described above, it is possible to prevent the dough 50 from slipping off the finger when pitching or throwing a ball, and the member 100 is arranged with the gap as described above, and the same By having the same shape and position, the fabric 50 of the finger portion can ensure breathability, and the finger can be easily bent and straightened.

The material constituting the member 60 of the fabric 50 includes, for example, natural rubber, synthetic natural rubber, silicone rubber, nitrile rubber, urethane rubber, EPDM, polyurethane resin, vinyl chloride resin, etc., and the materials described above may be selected. This allows you to avoid damaging the ball you are using. Among these, it is preferable that the member 60 contains silicone rubber. Silicone rubber has almost no reaction to body tissues, is odorless, and is physiologically inert, so it is suitable for use in products that come in direct contact with the human body (such as baby bottle nipples, mouthpieces, medical instruments, and medical materials). The reason why it is preferable for the member 60 to include silicone rubber is because it is a material that gives a sense of security to the wearer of the glove 1 and maintains elasticity even at low temperatures because it is widely used. Since the member 60 contains silicone rubber, the member 60 has elasticity, which increases the anti-slip effect, and maintains elasticity even in low temperature environments, so it can be used as a ball regardless of the season. It is possible to avoid scratches, and it is difficult to prevent the fabric 50 from freely expanding and contracting in accordance with the movement of the wearer's fingers, making it easier to grasp the ball. Further, it is preferable to provide protrusions, grooves, wrinkles, roughness, etc. on the surface of the member 60 to further enhance the anti-slip effect.

The thickness of the member 60 of the fabric 50 is preferably 100 μm or more and 800 μm or less, excluding portions such as protrusions, grooves, wrinkles, and grains. By setting the thickness of the member 60 to 800 μm or less, the wearer of the glove 1 can maintain a feeling similar to that of a bare hand, and can easily grip the ball.
In addition, by making the thickness of the member 60 100 μm or more, the member 60 ensures mechanical strength, and also reduces the degree of impact when the finger pad is hit by a batted ball, pitched ball, thrown ball, etc., and prevents the finger from getting hit. It can eliminate certain injuries or reduce the severity of injuries.

The thickness of the member 60 of the fabric 50 may be 800 μm or less, more preferably 600 μm or less, and even more preferably 400 μm or less. By setting the upper limit of the thickness of the member 100 of the finger material 50 to the above value, the wearer of the glove 1 can maintain a feeling similar to that of a bare hand, making it easier to grip the ball. The thickness of the member 100 of the fabric 50 may be 100 μm or more, more preferably 150 μm or more, and even more preferably 200 μm or more. By setting the lower limit of the thickness of the member 60 of the finger fabric 50 as above, the member 60 ensures mechanical strength and also reduces the degree of impact when the abdomen of the finger receives a batted ball, a pitched ball, a thrown ball, etc. This can eliminate or reduce the severity of injuries that the fingers may sustain.

The member 60 of the fabric 50 of the finger portion of the glove 1 in FIG. 1 covers the finger side as shown in FIG. 17, or the protrusion 11 covers the finger side as shown in FIG. Let's consider the case where it is arranged as follows. If the wearer of Glove 1 is a pitcher and, for example, throws a fastball or slider, the method of gripping the ball with the fingers before pitching is to support the ball with the finger side of the third finger of the fourth finger. Since the grip is considered to be common, for pitchers it is recommended that the member 60 on the third finger side of the fourth finger be shaped as shown in FIG. 17 and have as large an area as possible. Preferably, or as shown in FIG. 18, it is preferable that the protrusion 11 covers the finger side. Furthermore, for example, when a pitcher throws a forkball, he or she is likely to hold the ball between his or her second and third fingers. ) It is preferable that the member 60 has a shape as shown in FIG. 17 and has as large an area as possible, or it is preferable that the protrusion 11 covers the finger side as shown in FIG. 18. Furthermore, when a pitcher throws a changeup, he often grips the ball with the fourth finger side of his fifth finger. It is preferable that the member 60 has a shape as shown in FIG. 17 and has as large an area as possible, or it is preferable that the protrusion 11 covers the finger side as shown in FIG. 18. The wearer of the glove 1 can stably grip the ball by making the area of the member 60 on the finger side that contacts the ball as large as possible, or by having the protrusion 11 cover the finger side. He can maintain precise control when pitching or throwing a ball, similar to that with his bare hands. In addition, the way a pitcher grips the ball when throwing a curve ball is often unique to that pitcher, and depending on how the pitcher grips the ball, the side of the fingers that contact the ball may also be gripped. It is preferable that the member 60 has a shape as shown in FIG. 17 and has as large an area as possible, or that the protrusion 11 covers the finger side as shown in FIG. 18.

Furthermore, when the member 60 covers the finger side, as shown in FIG. 19, the member 100 inside the finger part is also arranged with the same shape and the same area at the same location as the member 60. It is preferable that the protrusion 11 is placed up to the finger side, and as shown in FIG. is preferred. This is because, at the moment of releasing the ball, it is necessary to prevent the member 60 in contact with the ball or the fabric 50 on which the protrusion 11 is placed from shifting relative to the fingers. This is because precise control can be maintained.
On the other hand, if the pitcher's grip on the ball is characterized by a finger side that does not come into contact with the ball, it is not necessary to place the member 60 or the protrusion 11 on that finger side. This is preferable because the fabric 50 can ensure better breathability.

(Regarding the member that covers the dorsal side of the finger part of the glove that is not the finger cot)
The fabric 50 on the dorsal side of the fingers of the glove 1 in FIG. Roughly, the area from the first joint to the second joint for the first finger, and from the first joint to the third joint for the second to fifth fingers), and the back of the second joint for the second to fifth fingers. It is preferable to have members 62 to 65 having rubber elasticity to cover, a member 61 having rubber elasticity to cover the back side of the finger, or a large number of protrusions 51. Note that the fabric 50 on the dorsal side of the fingers is not made of the same knitted fabric or elastic stretch fabric as the fabric on the palm side, but is made of, for example, woven fabric, nonwoven fabric, natural leather, synthetic leather, artificial leather, etc. If the fabric itself is considered to have a protective function that reduces the degree of injury when the back of the finger is hit by a batted ball, a pitched ball, or a thrown ball, members 61 to 65 or a number of protrusions are provided on the back of the finger. There is no need to have 51.

When the finger material 50 of the glove 1 in FIG. 2 has a member 61 on the dorsal side of the finger, the shape is, for example, a rectangle with a width of about 3 mm to 8 mm or rounded corners as shown in FIGS. 2 and 16. They are preferably rectangular in shape, and are preferably arranged in parallel with a gap of about 2 mm to 3 mm, for example. The shapes of the members 62 to 65 that cover the back surfaces of the second joints of the second to fifth fingers are, for example, a polygon with an area of about 1 to 3 square centimeters, a shape with rounded corners of a polygon, a circle, or an ellipse. , it is preferable to have a shape that is a combination of a curved line and a straight line.
By covering the dorsal side of the fingers with the members 61 to 65 of the fabric 50 of the finger portion, the wearer of the glove 1 can reduce the degree of impact when the back side of the finger is hit by a batted ball, a pitched ball, a thrown ball, etc. , it is possible to eliminate or reduce the degree of injury that may be caused to the fingers, and by being arranged in parallel with a gap, the fabric 50 can ensure breathability.
Note that FIG. 4 shows a case where the fabric 50 of the finger portion of the glove 1 in FIG. 2 does not have a member 61 having rubber elasticity but has a protrusion 51. When the protrusions 51 are arranged on the fabric 50 of the finger part of the glove 1 on the dorsal side of the fingers, the protrusions 51 are intended to prevent injuries, so they should have the same shape and the same shape as the protrusions 21 disposed on the fabric 20 on the back of the hand. Although any material may be used, it is preferable that the size of the protrusion 51 is smaller than that of the protrusion 21 because the shape of a finger has a larger curvature than the back of the hand.

When the protrusions 51 are arranged on the finger dorsal side of the fabric 50 of the finger portion of the glove 1 in FIG. Dimensions include a square with sides of 1 mm or more and 3 mm or less, or a shape with rounded corners of a square, a polygon with an area equivalent to a square with a side of 1 mm or more and 3 mm or less, a shape with rounded corners of a polygon, a circle, or an ellipse. The shape is preferably a combination of a curved line and a straight line, the height is preferably about 0.5 mm to 3 mm, and the protrusions are preferably arranged at intervals of about 1 mm to 3 mm. By setting the shape and height of the protrusions 51 as described above, and by arranging them at intervals of about 1 mm to 3 mm, ventilation of the fingers can be ensured, and the wearer of the glove 1 can easily hit or pitch a ball. When a pitched ball is directly received on the finger dorsum, the degree of impact received by the finger dorsum can be reduced, thereby eliminating or reducing the degree of injury that may be caused to the finger dorsum.

When the members 61 are arranged on the fabric 50 of the finger portion of the glove 1 as shown in FIG. 2, it is preferable that they are arranged in parallel with an interval of about 2 mm to 3 mm, for example. By arranging the members 61 in parallel with an interval of, for example, about 2 mm to 3 mm, it is possible to provide breathability to the fingers and prevent heat buildup, and at the same time, the finger fabric 50 can maintain elasticity and It can make bending and straightening easier.

The materials composing the members 61 to 65 of the glove 1 in FIG. 2 and the finger protrusions 51 in FIG. 4 are, for example, natural rubber, synthetic natural rubber, silicone rubber, nitrile rubber, urethane rubber, EPDM, polyurethane resin, Examples include vinyl resin, but by selecting the materials described above, it is possible to avoid damaging the ball used. Among these, it is preferable that the members 61 to 65 and the protrusion 51 contain silicone rubber. Silicone rubber has almost no reaction to body tissues, is odorless, and is physiologically inert, so it is suitable for use in products that come in direct contact with the human body (such as baby bottle nipples, mouthpieces, medical instruments, and medical materials). The reasons why it is preferable for the members 61 to 65 and the protrusion 51 to include silicone rubber are because the material is widely used, gives a sense of security to the wearer of the glove 1, and maintains elasticity even at low temperatures. be. Since the members 61 to 65 and the protrusion 51 contain silicone rubber, they maintain their elasticity even in low temperature environments, making it possible to avoid damaging the ball and make it easy to wear regardless of the season. Since it is difficult to prevent the dough 50 from freely expanding and contracting according to the movement of the user's fingers, it becomes easier to grasp the ball.

When the members 61 to 65 are arranged on the fabric 50 of the finger portion of the glove 1 in FIG. 2, the thickness of the members 61 to 65 is preferably 300 μm or more and 3000 μm (3 mm) or less. By setting the thickness of the members 61 to 65 of the finger fabric 50 to 300 μm or more, the degree of impact received by the fingers when the wearer of the glove 1 receives a batted ball, a pitched ball, a thrown ball, etc. on the back of the fingers is reduced, Injuries that may be caused to the fingers can be eliminated or the degree of injury can be reduced, and by setting the thickness to 3000 μm (3 mm) or less, the weight of the glove 1 can be reduced.

The thickness of the members 61 to 65 of the fabric 50 of the finger portion of the glove 1 in FIG. 2 may be 300 μm or more, preferably 600 μm or more, more preferably 1000 μm (1 mm) or more, and 1500 μm (1 mm) or more. 5 mm) or more is more preferable. By setting the lower limit of the thickness of the members 61 to 65 of the finger fabric 50 as above, it is possible to reduce the degree of impact that the fingers receive when the wearer of the glove 1 receives a batted ball, a pitched ball, a thrown ball, etc. on the back of the finger. This can eliminate or reduce the degree of injury that the finger may sustain. The thickness of the members 61 to 65 of the finger material 50 may be 3000 μm (3 mm) or less, preferably 2500 μm (2.5 mm) or less, and more preferably 2000 μm (2 mm) or less. By setting the upper limit of the thickness of the members 61 to 65 of the finger fabric 50 to the above value, the glove 1 can be made lighter.

(About the arm of the glove)
As shown in FIG. 1 on the palm side and FIG. 2 on the back of the hand, the glove 1 preferably has an arm 120 connected to the center of the glove body, and the arm 120 preferably includes a fastener 121. . The length of the arm portion 120 (length from the wrist to the elbow) may be about 3 cm to 5 cm, and by fixing the arm portion 120 to the wrist with the fastener 121, the wearer of the glove 1 can pitch or pitch. When throwing a ball, centrifugal force applied to the glove can prevent the central part of the glove body from shifting in the throwing direction. Since the central portion of the glove body can be prevented from shifting in the throwing direction, it is possible to prevent the finger portions of the glove body from shifting in the throwing direction.
Originally, the fingers have anti-slip members 100 or protrusions 101 on the back side of the fabric 50, so the fingers do not shift. However, for example, if your fingers accidentally come into strong contact with a glove, uniform, cap, belt, etc. during a game and are rubbed strongly, that is, when a force other than the centrifugal force of pitching or throwing is applied, the fabric 50 may We cannot deny the possibility that it will deviate. The fastener 121 of the arm portion 120 has a fail-safe role that further prevents the fingers of the glove body from slipping. Among these, it is preferable to use a hook-and-loop fastener for the fastener 121. Possible methods for fixing the male and female sides of the hook-and-loop fastener to the arm portion 120 include sewing, welding, and gluing.

By employing a hook-and-loop fastener for the fastener 121, the wearer of the glove 1 can quickly and easily fine-tune the degree of tightening of the wrist. Further, the hook-and-loop fastener is preferably placed so as to cover the ulnar suprastyloid process and the radial styloid process of the wrist. The ulnar supramidual process and radial styloid process of the wrist are prone to bruises and fractures when hit, thrown, or pitched, and the hook-and-loop fastener is placed to cover the ulnar supramidual process and radial styloid process of the wrist. By doing so, the wrist of the wearer of the glove 1 can be protected from injury due to the thickness of the hook-and-loop fastener.
Further, the fastener 121 may be configured such that the male and female sides of a hook-and-loop fastener are attached to a belt having an elastic material portion with a buckle, so that the tightness can be finely adjusted. It is preferable that the belt covers the ulnar suprastyloid process and the radial styloid process of the wrist, and the thickness of the belt can protect the wrist of the wearer of the glove 1 from injury.

The arm portion 120 is preferably made of the same knitted fabric or elastic stretch fabric as the fabric 10 of FIG. 1 on the palm side of the glove 1 or the fabric 20 of FIG. 2 on the back side of the hand. Since the arm portion 120 is made of a knitted fabric or an elastically stretchable fabric, the wearer of the glove 1 can secure the wrist with the fastener 121 without damaging the wrist.

The fastener 121 may be a button, a zipper, a zipper, a hook, a string, etc. other than a hook-and-loop fastener.
Further, it is conceivable that a fastener including a hook-and-loop fastener is employed not on the arm 120 but on, for example, the outside of the palm, the palm of the hand, or the back of the hand. In this case, the arm portion 120 is omitted. If the arm portion 120 is omitted, it is not possible to protect the ulnar styloid process and the radial styloid process arm portion of the wrist, but the glove 1 can be made lighter and lower in cost. You can get the advantage of being able to

(About the materials that make up the fabric of glove 1)
Materials constituting the fabric 10 shown in FIG. 1 on the palm side of the glove 1, the fabric 20 shown in FIG. However, it is preferable that the materials constituting the palm fabric 10, the back fabric 20, and the finger fabric 50 contain 50% or more of nylon. By containing 50% or more of nylon in the materials constituting the palm fabric 10, the back of the hand fabric 20, and the finger fabric 50, the glove 1 can be made lightweight and can be given flexibility and durability. .

The fabric 10 on the palm side and the fabric 20 on the back side of the glove 1 may be knitted fabric, woven fabric, non-woven fabric, or a combination of these fabrics, but preferably knitted fabric, including the fabric 50 on the finger portions. Preferably, the knitted fabric has a bare jersey texture. Since the knitted fabrics of the palm area fabric 10, the back area fabric 20, and the finger area fabric 50 are bare jersey textures, the palm area fabric 10, the back area fabric 20, and the finger area fabric 50 have elasticity. Obtainable. In addition, when the fabric 10 for the flat part and the fabric 20 for the back of the hand are a combination of knitted fabric, woven fabric, non-woven fabric, etc., sewing, welding, adhesion, etc. can be considered as a method for joining them.

The fabric 10 shown in FIG. 1 on the palm side of the glove 1, the fabric 20 shown in FIG. Preferably, it contains 70% or more of polyurethane, more preferably 80% or more, still more preferably 5% or more of polyurethane, and even more preferably 10% or more. By setting the blending ratio of nylon and polyurethane for the palm fabric 10, the back fabric 20, and the finger fabric 50 of the glove 1 as described above, the good thermal conductivity of the materials can be applied to the glove 1. This allows the wearer of the glove 1 to feel a cool sensation on his or her hands.

The average fineness of the fibers constituting the fabric 10 for the palm, the fabric 20 for the back of the hand, and the fabric 50 for the fingers of the glove 1 is preferably 80 denier or less, more preferably 70 denier or less. , more preferably 65 denier or less, even more preferably 60 denier or less. By setting the average fineness of the fabric 10 of FIG. 1 on the palm side of the glove 1, the fabric 20 of FIG. The fabric can more easily follow the movements of the wearer's hands and fingers.
Further, the average fineness of the fibers constituting the fabric 10 for the palm, the fabric 20 for the back of the hand, and the fabric 50 for the fingers of the glove 1 is preferably 30 denier or more, and preferably 40 denier or more. More preferably, it is 50 deniers or more, even more preferably. By setting the average fineness of the fabric 10 shown in FIG. 1 on the palm side of the glove 1, the fabric 20 shown in FIG. Can be done.
In addition, if fibers with a fineness of 30 to 40 denier are used, it is thought that it will be easier to ensure breathability, and it can be used for gloves for games and practices in the summer when the temperature rises. The use of this fiber makes it difficult for heat to escape due to its lower breathability, and is thought to play a role in protecting against the cold, making it ideal for use in gloves for games and practices during the cold winter months, or on chilly days in the spring and fall. It is thought that it can be done.
Furthermore, the fabric 10 of FIG. 1 on the palm side of the glove 1, the fabric 20 of FIG. Fibers with different finenesses may be used, such as giving priority to durability, using fibers of 60 to 80 denier, and using fabric 50 of 30 to 40 denier, for example, to pursue smoothness of finger movement. .

(About the elongation rate of the fabric of the finger part of glove 1)
The lateral elongation rate of the finger fabric 50 when the glove 1 is worn may vary depending on the finger area, but is preferably about 1% or more and 30% or less. The lateral elongation rate is calculated by comparing the outer circumference of each part of the wearer's finger of the glove 1 with the inner circumference of the fabric 50 in an unloaded state, and calculates how much the inner circumference of the fabric 50 stretches at that part of the finger. It is defined here as something that calculates whether The reason why the elongation rate in the lateral direction is preferably about 1% or more and 30% or less is because the members 60 to 65 and the member 100 do not stretch as much as the fabric 50, so when the glove 1 is worn, the fabric 50 is partially stretched. This is because there is a possibility that the fabric 50 has a portion that stretches significantly, which may cause problems such as deterioration of the fabric 50 or peeling of the member from that portion.
Further, when the glove 1 is worn, if the pressure applied to the finger by the fabric 50 of the finger portion is large, the entire finger may become numb or uncomfortable due to obstruction of blood flow, which is inconvenient. In order to prevent numbness or discomfort in the fingertips, it is preferable to suppress the pressure that the fingers receive from the fabric 50 when wearing the glove 1 to about 0.04 to 0.10 N/cm2.

When the glove 1 is worn, the vertical elongation rate of the finger fabric 50 is preferably a value that is close to that of all five fingers, and is approximately 1% or more and 10% or less when the wearer's fingers are stretched. preferable. The elongation rate in the longitudinal direction is defined here as a calculation of how much the fabric 50 stretches in the length direction from an unloaded state with respect to the length direction of the fingers of the wearer of the glove 1. The reason why the elongation rate in the longitudinal direction is preferably between 1% and 10% is that the smaller the return stress applied to the knitted fabric 50 in the length direction, the easier it is to bend and straighten the fingers. This is because the feeling of stiffness in the body can be suppressed.

(About the gusset part of the gloves)
For example, as shown in FIG. 23 on the back of the hand, the glove 1 preferably has gusset fabrics 110 and 111 along the outside of the palm between the palm fabric 10 and the back fabric 20 and in the first interdigital space. Furthermore, it is preferable to have the gusset material 112 in the spaces between the second to fourth fingers, which are the parts corresponding to the webs.
