This non-provisional application is based on, and claims priority to, Japanese Patent Application No. 2022-159725 filed on Oct. 3, 2022 with the Japan Patent Office, the entire contents of which are hereby incorporated by reference.
The present invention relates to a sports glove.
Conventionally, in a sports glove used in a competition for gripping a spherical body, a rod-shaped body, or the like, in order to improve a fit feeling of a wearer with respect to a hand and to improve a gripping state, a measure such as arranging a material having excellent stretchability has been made. Japanese Patent Laying-Open No. 2002-65928 discloses a sports glove having a band disposed on at least one of a little finger portion, a ring finger portion, and a middle finger portion. In Japanese Patent Laying-Open No. 2002-65928, by providing such a band, when a target object is gripped, at least one of a little finger, a ring finger, and a middle finger is tightened by the band, so that the target object can be gripped firmly with the little finger, the ring finger, and the middle finger rather than the thumb and the index finger.
However, in the above-described sports glove, there is room for improvement in the gripping state of the target object.
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a sports glove capable of realizing a good gripping state when the wearer grips a target object.
A sports glove according to the present disclosure includes an index finger portion, a middle finger portion, a ring finger portion, and a little finger portion, a back portion, and a first resistance portion. The index finger portion, the middle finger portion, the ring finger portion, and the little finger portion are capable of respectively receiving the index finger, the middle finger, the ring finger, and the little finger of a hand of a wearer. The back portion is connected to the index finger portion, the middle finger portion, the ring finger portion, and the little finger portion. The back portion covers a back of the wearer's hand. The first resistance portion has flexibility. The first resistance portion is disposed on at least one selected from the group consisting of the back portion, the ring finger portion, and the little finger portion such that when the wearer bends the index finger, the middle finger, the ring finger, and the little finger respectively received by the index finger portion, the middle finger portion, the ring finger portion, and the little finger portion, a magnitude of bending resistance applied to the little finger or the ring finger is greater than a magnitude of bending resistance applied to the middle finger or the index finger.
According to the above, it is possible to obtain a sports glove capable of realizing a good gripping state when the wearer grips the target object.
The foregoing and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.
Hereinafter, embodiments of the present invention will be described. Note that, unless otherwise specified, the same or corresponding parts in the following drawings are denoted by the same reference numerals, and the description thereof will not be repeated.

As shown in
Bending resistance R corresponds to a bending moment M generated in resistance portion 7 when the wearer bends index finger 101B4, middle finger 101B3, ring finger 101B2, and little finger 101B1 respectively received by index finger portion 40, middle finger portion 30, ring finger portion 20, and little finger portion 10. As illustrated in
First resistance portion 70a is disposed on surface S of back portion 60a, ring finger portion 20, and little finger portion 10. Second resistance portion 70b is disposed on surface S of back portion 60a, middle finger portion 30, and index finger portion 40. First resistance portion 70a includes a little finger resistance portion 71 and a ring finger resistance portion 72. Second resistance portion 70b includes a middle finger resistance portion 73 and an index finger resistance portion 74. Little finger resistance portion 71 is arranged on surface S of back portion 60a and little finger portion 10. Ring finger resistance portion 72 is disposed on surface S of back portion 60a and ring finger portion 20. Middle finger resistance portion 73 is disposed on surface S of back portion 60a and middle finger portion 30. Index finger resistance portion 74 is disposed on surface S of back portion 60a and index finger portion 40. Little finger resistance portion 71 and ring finger resistance portion 72 may be integrally connected at back portion 60a, or may be disposed separately from each other. Middle finger resistance portion 73 and index finger resistance portion 74 may be integrally connected by back portion 60a, or may be disposed separately from each other. By providing such resistance portion 7, it is also possible to suppress generation of slack and wrinkles in palm portion 60b.
Here, a feature of sports glove 1 according to the present embodiment is that, resistance portion 7 is configured such that a load applied to little finger 101B1 and ring finger 101B2 in the hand wearing glove 1 becomes larger than the load applied to index finger 101B4 and middle finger 101B3 in the hand wearing glove 1 when the wearer grips the target object with the hand wearing glove 1.
In general, when the target object is gripped, the target object tends to be gripped so as to be tightened with index finger 101B4 having a large force (hereinafter referred to as finger force) generated by the finger. However, the inventors have found that it is effective to consciously grip the target object with a finger having a small finger force in order to realize a good gripping state with excellent operability with respect to the target object. The finger force of middle finger 101B3, ring finger 101B2, and little finger 101B1 is smaller than the finger force of index finger 101B4. On the other hand, when the load is applied to middle finger 101B3, ring finger 101B2, and little finger 101B1, it is possible to turn attention to these fingers, and as a result, it is possible to reliably grip the target object with these fingers. Therefore, resistance portion 7 is provided such that bending resistance R to be applied to at least one of middle finger 101B3, ring finger 101B2, and little finger 101B1 is greater than bending resistance R to be applied to index finger 101B4 when the target object is gripped with the hand with glove 1 fitted, whereby a good gripping state with respect to the target object can be realized.
On the other hand, a difference between an average value of the finger forces of middle finger 101B3 and an average value of the finger forces of index finger 101B4 is less than 1 kgf. In particular, considering the standard deviation, it can be seen that a value obtained by adding the standard deviation to the average value of the finger forces of middle finger 101B3 is larger than a value obtained by subtracting the standard deviation from the average value of the finger forces of index finger 101B4. In other words, it is considered that there are a certain number of cases where the finger force of middle finger 101B3 is larger than the finger force of index finger 101B4. However, a value obtained by subtracting the standard deviation from the average value of the finger forces of middle finger 101B3 is larger than a value obtained by adding the standard deviation to the average value of the finger forces of ring finger 101B2. In addition, a value obtained by subtracting the standard deviation from the average value of the finger forces of ring finger 101B2 is larger than a value obtained by adding the standard deviation to the average value of the finger forces of little finger 101B1. From this, in order to realize a good gripping state of the target object, it is considered more preferable to consciously grip the target object with ring finger 101B2 and little finger 101B1 by turning their attention to these fingers. Therefore, in order to realize a good gripping state of the target object, it is preferable to dispose resistance portion 7 such that the load applied to ring finger 101B2 and little finger 101B1 is larger than the load applied to index finger 101B4 and middle finger 101B3.
With reference to
In this way, the number of joint portions in first joint portion 4 straddled by first resistance portion 70a is larger than the number of joint portions in second joint portion straddled by second resistance portion 70b. As illustrated in
In sports glove 1, resistance portion 7 may be disposed such that when the wearer bends index finger 101B4, middle finger 101B3, ring finger 101B2, and little finger 101B1 respectively received by index finger portion 40, middle finger portion 30, ring finger portion 20, and little finger portion 10, the magnitude of bending resistance R applied to little finger 101B1 or ring finger 101B2 is greater than the magnitude of bending resistance R applied to middle finger 101B3 or index finger 101B4. Therefore, glove 1 may not include second resistance portion 70b. In this way, even if the wearer bends the index finger 101B4 and middle finger 101B3 respectively received by index finger portion 40 and middle finger portion 30, the load is not applied to middle finger 101B3 or index finger 101B4 because there is no bending resistance R applied from the resistance portion to middle finger 101B3 or index finger 101B4. As a result, the magnitude of bending resistance R applied to little finger 101B1 or ring finger 101B2 becomes greater than the magnitude of bending resistance R applied to middle finger 101B3 or index finger 101B4.
From the graph illustrated in
In sports glove 1, resistance portion 7 may be disposed such that the magnitude of bending resistance R applied to little finger 101B1 is greater than the magnitude of bending resistance R applied to ring finger 101B2 when the wearer bends the finger. Therefore, glove 1 may not include ring finger resistance portion 72. In this way, in a case where the wearer bends the finger, since there is no bending resistance R applied from ring finger resistance portion 72 to ring finger 101B2, no load is applied to ring finger 101B2. As a result, the magnitude of bending resistance R applied to little finger 101B1 is greater than the magnitude of bending resistance R applied to ring finger 101B2.
From the graph shown in
In sports glove 1, resistance portion 7 may be disposed such that the magnitude of bending resistance R applied to middle finger 101B3 is greater than the magnitude of bending resistance R applied to index finger 101B4 when the wearer bends the finger. Therefore, glove 1 may not include index finger resistance portion 74. In this way, in a case where the wearer bends the finger, since there is no bending resistance R applied from index finger resistance portion 74 to index finger 101B4, no load is applied to index finger 101B4. As a result, the magnitude of bending resistance R applied to middle finger 101B3 is greater than the magnitude of bending resistance R applied to index finger 101B4.
In particular, it is considered that it is most preferable to arrange resistance portion 7 such that the load applied to little finger 101B1, ring finger 101B2, middle finger 101B3, and index finger 101B4 decreases in this order when the wearer bends the finger. Therefore, the number of little finger resistance portions 71, ring finger resistance portions 72, middle finger resistance portions 73, and index finger resistance portions 74 each straddle the joint portion may be reduced in this order.
Note that, a magnitude relationship of the number of joint portions straddled by each of resistance portions 7 may match a magnitude relationship of bending resistance R in each of resistance portions 7. Therefore, first resistance portion 70a may be disposed so as to straddle over at least one joint selected from the group consisting of first metacarpophalangeal joint portion 11a, first proximal interphalangeal joint portion 11b, first distal interphalangeal joint portion 11c, second metacarpophalangeal joint portion 21a, second proximal interphalangeal joint portion 21b, and second distal interphalangeal joint portion 21c. Second resistance portion 70b may be disposed on at least one joint portion selected from the group consisting of third metacarpophalangeal joint portion 31a, third proximal interphalangeal joint portion 31b, third distal interphalangeal joint portion 31c, fourth metacarpophalangeal joint portion 41a, fourth proximal interphalangeal joint portion 41b, and fourth distal interphalangeal joint portion 41c.
Rigidity EI of first resistance portion 70a may be larger than rigidity EI of second resistance portion 70b. Bending moment M generated in resistance portion 7 when the wearer bends the finger corresponds to a value obtained by multiplying the curvature by rigidity EI. For example, when rigidity EI of first resistance portion 70a is larger than rigidity EI of second resistance portion 70b, the magnitude of bending resistance R applied to little finger 101B1 or ring finger 101B2 is greater than the magnitude of bending resistance R applied to middle finger 101B3 or index finger 101B4 when the wearer bends the finger.
In addition, rigidity EI is a value obtained by multiplying second moment of area I in a cross section determined from a cross-sectional shape in an arbitrary cross section by the Young's modulus E that is a physical property value of a material. When bending resistance R in resistance portion 7 is adjusted, not only the number of joint portions straddled by resistance portion 7 but also a shape and material of resistance portion 7 may be changed.
As illustrated in
The cross-sectional shape of first resistance portion 70a illustrated in
The material of resistance portion 7 in the present embodiment is, for example, silicon resin. Since resistance portion 7 only needs to have flexibility, the material of resistance portion 7 may be, for example, natural leather, synthetic leather, artificial leather, knit material, urethane, silicon rubber, rubber, or the like. The materials of first resistance portion 70a and second resistance portion 70b may be the same material or different materials. Bending moment M generated in resistance portion 7 when the wearer bends the finger also depends on the Young's modulus E of the material of resistance portion 7. Therefore, in a case where the material of first resistance portion 70a and the material of second resistance portion 70b are different from each other, for example, the material of first resistance portion 70a may be natural leather, and the material of second resistance portion 70b may be the knit material. The Young's modulus E of the natural leather is larger than the Young's modulus E of the knit material. In this way, rigidity EI of first resistance portion 70a is larger than rigidity EI of second resistance portion 70b.
Since rigidity EI of first resistance portion 70a only needs to be larger than rigidity EI of second resistance portion 70b, the respective materials of little finger resistance portion 71, ring finger resistance portion 72, middle finger resistance portion 73, and index finger resistance portion 74 may be appropriately changed so that rigidity EI of first resistance portion 70a is larger than rigidity EI of second resistance portion 70b. Note that, the Young's modulus E can be measured by performing a tensile test of a target material.

First resistance portion 70a has flexibility. First resistance portion 70a is disposed on at least one selected from the group consisting of back portion 60a, ring finger portion 20, and little finger portion 10 such that when the wearer bends index finger 101B4, middle finger 101B3, ring finger 101B2, and little finger 101B1 respectively received by index finger portion 40, middle finger portion 30, ring finger portion 20, and little finger portion 10, the magnitude of bending resistance R applied to little finger 101B1 or ring finger 101B2 is greater than the magnitude of bending resistance R applied to middle finger 101B3 or index finger 101B4.
In this way, when the wearer bends the finger, the magnitude of bending resistance R applied to little finger 101B1 or ring finger 101B2 is greater than the magnitude of bending resistance R applied to middle finger 101B3 or index finger 101B4. As a result, the wearer can consciously grip the target object with little finger 101B1 and ring finger 101B2 with a weak finger force, so that a good gripping state can be realized with respect to the target object. For example, in a case where the target object to be gripped is a baseball bat 200, since the gripping state of bat 200 is good and the operability is improved, the wearer can improve the swing speed of bat 200. In addition, by providing resistance portion 7, it is also possible to suppress generation of slack and wrinkles in palm portion 60b.

In this way, when the wearer bends the finger, the magnitude of bending resistance R applied to little finger 101B1 is greater than the magnitude of bending resistance R applied to ring finger 101B2.
In sports glove 1, first resistance portion 70a further includes ring finger resistance portion 72. Ring finger resistance portion 72 is disposed on at least one of back portion 60a and ring finger portion 20.
