Description

  The present invention relates to a ball catcher for baseball and softball.

Conventionally, ball catching tools (grabs) for baseball and softball are generally hard at the time of purchase and insufficient in flexibility. Therefore, if it is used as it is, the ball cannot be tightly wrapped, and mistakes are likely to occur in the catching operation.
In order to increase the flexibility of the ball catcher immediately after purchase, measures such as striking and stretching the leather, which is a component of the ball catcher, with a wooden mallet, or softening the leather by soaking the ball catcher in hot water, are taken. May be. However, such a measure shortens the life of the leather and reduces the durability of the ball catcher.
For this reason, a ball catcher aimed at obtaining sufficient flexibility from the beginning of purchase has been proposed (see, for example, Patent Documents 1 and 2).

On the other hand, the catching tool has a demand for securing a sufficient catching area in order to increase the certainty of catching. In general, the ball catching tool is closed by closing the thumb bag and the little finger bag close to each other and making the catching surface fold in three folds (vertically closed), with the index finger bag and middle finger bag on the bank. It is known as “shallow closing (horizontal closing)” in which the catching surface portion is folded in two so as to be close to each other. A deep catch can secure a wider catching area than a shallow close.
For this reason, in order to secure a sufficient catching area, it is only necessary to make it easy to close the catching tool deeply. Therefore, it is necessary to carry out a so-called break-in operation for attaching a crease of a trifold fold. Therefore, it is difficult to secure a sufficient catching area from the beginning.
The ball catching tools described in Patent Documents 1 and 2 focus only on improving the flexibility, and do not consider securing a sufficient ball catching area.

Hereinafter, a ball catcher according to an embodiment of the present invention will be described with reference to the accompanying drawings as appropriate. In this embodiment, a case where the ball catching device is a baseball glove will be described as an example.
FIG. 1 is a diagram showing a ball catching tool (baseball glove) according to an embodiment of the present invention. FIG. 1A is an overall configuration diagram as viewed from the front (when viewed from a direction facing the catching surface portion of the catching tool body), and FIG. 1B is a fastening of a back pad 31 that supports the back of the hand. It is the figure which represented the flat back part vicinity by the front view in the state which solved. In addition, since the bending promotion part 4 shown to Fig.1 (a) is covered with the catching surface part 1, it is not actually visible but only shows the position.
As shown in FIG. 1, a ball catching device 100 according to the present embodiment, like a conventional ball catching device, is disposed on the back side of the hand with respect to the ball catching portion 1 in contact with the ball and the ball catching portion 1. The ball catching tool main body 10 which comprises the flat back part 2 which contacts and the back part 3 arrange | positioned rather than the flat back part 2 at the back of the hand is provided. And the catcher 100 which concerns on this embodiment comprises the bending promotion part 4 in which the flat back part 2 promotes the bending | flexion to the catching-sphere part 1 side of the catcher main body 10, and this bending promotion part 4 is comprised. It has one feature in that it is arranged under specific arrangement conditions.

FIG. 2 is a diagram schematically showing a configuration example of the front and back views of the flat back before assembling the ball catcher main body of the present embodiment. FIG. 2A is a diagram illustrating the first ball catching region, the first region, and the second region in the flat back portion, and FIG. 2B is a diagram illustrating the bending promoting portion provided in the flat back portion. is there.
As shown in FIG. 2, the flat back part 2 excludes each finger part (thumb part 21, index finger part 22, middle finger part 23, ring finger part 24, little finger part 25) that comes into contact with the palm of the finger and each finger part. The palm part 26 is comprised. The palm portion 26 includes a first catching area C1, a first area A1, and a second area A2.

  Here, as shown to Fig.2 (a), let the end point by the side of the thumb part 21 of the index finger part 22 of the flat back part 2 be the 1st vertex P1. A root point between the middle finger portion 23 of the flat back portion 2 and the ring finger portion 24 of the flat back portion is defined as a second vertex P2. A midpoint of a line segment connecting the first vertex P1 and the second vertex P2 of the flat back portion 2 is defined as a third vertex P3. An end point on the thumb portion 21 side of the hand insertion edge 27 of the flat back portion 2 is defined as a fourth vertex P4. The end point on the little finger part 25 side of the hand insertion edge 27 of the flat back part 2 is defined as a fifth vertex P5. An end point on the base index finger portion 22 side of the thumb portion 21 of the flat back portion 2 is defined as a sixth vertex P6. An end point outside the base of the little finger part 25 of the flat back part 2 is defined as a seventh vertex P7. The midpoint of the line segment connecting the fifth vertex P5 and the seventh vertex P7 of the flat back portion 2 is defined as an eighth vertex P8.

The “end point on the thumb part 21 side of the index finger part 22 of the flat back part 2” that defines the first vertex P1 is the distance between the index finger part 22 of the flat back part 2 and the middle finger part 23 of the flat back part 2. It means an intersection when a straight line connecting the base point and the second vertex P2 intersects the edge of the flat back part 2 on the index finger part 22 side.
Further, the hand insertion edge 27 is an edge of a part that partitions the hand insertion port 11 (see FIG. 1) when the ball catching tool body 10 is assembled.
Further, the “end point outside the root of the little finger part 25 of the flat back part 2” defining the seventh vertex P7 is the end point on the little finger part 25 side of the ring finger part 24 of the flat back part 2 and the second vertex P2. Means a point of intersection when the straight line crossing the edge of the flat back 2 on the little finger 25 side.
The “end point on the index finger part 22 side of the base of the thumb part 21 of the flat back part 2” that defines the sixth vertex P6 is the root of the web 6 on the thumb part 21 side when the ball catching tool body 10 is assembled. It corresponds to the point that hits the corner.
Further, the eighth vertex P8 is the midpoint of the line segment connecting the fifth vertex P5 and the seventh vertex P7 of the flat back portion 2, but when this midpoint is not located on the edge of the flat back portion 2, The eighth vertex P8 means a point on the edge of the flat back portion 2 that is the shortest distance from this midpoint.

As shown in FIG. 2A, the first catching region C1 includes a line segment connecting the third vertex P3 and the fourth vertex P4, and a flat back portion 2 between the fourth vertex P4 and the fifth vertex P5. This is a substantially triangular area partitioned by the edge (that is, the hand insertion edge 27) and a line segment connecting the fifth vertex P5 and the third vertex P3. Area of the first catching area C1, for example, when it for a typical adult baseball glove on the ^market, a 55cm ² ~85cm 2.
The first area A1 includes a line segment connecting the second vertex P2 and the third vertex P3, a line segment connecting the third vertex P3 and the fifth vertex P5, and a plane between the fifth vertex P5 and the eighth vertex P8. This is a substantially quadrangular area defined by the edge 28 of the back portion 2 and a line segment connecting the eighth vertex P8 and the second vertex P2. Area of the first area A1, for example, when it for a typical adult baseball glove on the ^market, a 35cm ² ~55cm 2.
The second area A2 includes a line segment connecting the third vertex P3 and the first vertex P1, the edge 29 of the flat back portion between the first vertex P1 and the sixth vertex P6, and the sixth vertex P6 and the fourth vertex. It is a substantially quadrangular region partitioned by a line segment connecting P4 and a line segment connecting the fourth vertex P4 and the third vertex P3. Area of the second area A2, for example, when it for a typical adult baseball glove on the ^market, a 50cm ² ~68cm 2.

As shown in FIG. 2B, the bending promoting portion 4 includes a first bending promoting portion 41 that is entirely located in the first region A1, and a second bending promoting portion that is entirely located in the second region A2. 42 and is not substantially formed in the first catching region C1. Here, the fact that the bending promoting portion 4 is “not substantially formed” in the first catching region C1 includes not only the case where the bending promoting portion 4 does not enter at all in the first catching region C1. This means that even a slight entry due to manufacturing variation is allowed. Specifically, even if the bending promoting portion 4 slightly enters the first catching region C1, if the area of the portion is less than 5% of the area of the first catching region C1, the bending promoting portion 4 Can be regarded as not being formed in the first catching region C1. If the area of the portion of the bending promoting portion 4 that has entered the first catching region C1 is about this level, the first catching region C1 is not greatly bent and the catching region is not easily crushed.
Further, “the whole is located in the first region A1” of the first bending promotion portion 41 basically means that the whole (the entire area) of the first bending promotion portion 41 is located in the first region A1. However, it is allowed until it slightly protrudes from the first region A1 due to manufacturing variation or the like. More specifically, if the area of the portion that protrudes from the first region A1 of the first bending promotion portion 41 is less than 5% of the area of the first bending promotion portion 41, the entire first bending promotion portion 41 is the first. It can be considered that it is located in the region A1. The same applies to the meaning of “the whole is located in the second region A2” of the second bending promoting portion 42.

As shown in FIG. 2 (b), the first bending promoting portion 41 is formed from the position on the edge 28 of the flat back portion 2 between the fifth vertex P5 and the eighth vertex P8 in the first region A1. 2 is a shape extending toward the inner side. The second bending promoting portion 42 has a shape extending from the position on the edge 29 of the flat back 2 between the first vertex P1 and the sixth vertex P2 in the second region A2 toward the inside of the flat back 2. It is.
Further, the first bend promoting portion 41 and the second bend promoting portion 42 each have a shape in which the width gradually decreases toward the inside of the flat back portion 2. Note that the “width” in the “shape in which the width gradually decreases” means a dimension in a direction orthogonal to the direction in which the first bend promoting portion 41 and the second bend promoting portion 42 extend in a front view.
More specifically, each of the first bending promotion portion 41 and the second bending promotion portion 42 has a V-shape when viewed from the front.

FIG. 3 is a diagram schematically showing variations in the front-view shape of the first bending promotion portion 41 and the second bending promotion portion 42.
As the shape that gradually decreases in width toward the inner side of the flat back portion 2, as shown in FIGS. 3 (a) to 3 (c), an elliptical arc shape and a trapezoidal shape as well as the V shape shown in FIG. 2 (b). It may be stepped. The first bend promoting portion 41 and the second bend promoting portion 42 may have, for example, a rectangular shape as shown in FIG. Furthermore, as shown in FIG. 3E, the first bend promoting portion 41 and the second bend promoting portion 42 have the above-described overall shape of the assembly of a plurality of small through holes 43 penetrating the flat back portion 2. Such various shapes may be used. Note that the overall shape of the aggregate of the through holes 12 is a shape formed by the envelope E of the through hole 12 located outside the aggregate of the through holes 12.
The first bend promoting portion 41 and the second bend promoting portion 42 may have the same shape or different shapes.

Although it is considered that the larger the first bending promoting portion 41 is, the higher the flexibility of the ball catching device 100 (flat back portion 2) is, but if too large, the durability of the ball catching device 100 (flat back portion 2) is lowered. It becomes easy to invite. Therefore, the area of the first bending promoting portion 41 is preferably set to 40% or less of the area of the first region A1. On the other hand, if the first bending promoting portion 41 is too small, sufficient flexibility cannot be obtained. Therefore, the area of the first bending promoting portion 41 is preferably set to 10% or more of the area of the first region A1. That is, the area of the first bending promotion portion 41 is preferably set to an area of 10% to 40% of the area of the first region A1.
For the same reason, the area of the second bending promoting portion 42 is preferably set to an area of 5% to 30% of the area of the second region A2.

  The bending promoting part 4 is formed of any one of a cut, a notch and a groove. In the present embodiment, the bending promoting portion 4 is formed of a notch and an elastic member 5 (see FIG. 1) that is more easily expanded and contracted than the flat back portion 2 attached in the notch. As a material of the elastic member 5, for example, synthetic fiber or natural fiber fabric, synthetic fiber or natural fiber knitted fabric, rubber, or the like can be used. As synthetic fibers, nylon, polyester, polyurethane and the like can be used, and as natural fibers, cotton, hemp, silk, rayon and the like can be used.

  As described above, the bending promoting portion 4 of the present embodiment includes the first bending promoting portion 41 located in the first region A1 and the second bending promoting portion 42 located in the second region A2. And is not substantially formed in the first catching region C1. In other words, the first bending promotion portion 41 and the second bending promotion portion 42 may have dimensions that extend to a position in contact with the first catching region C1. It is possible to secure a sufficient catching area by the first catching area C1 while enhancing the bendability of the catching tool 100 (flat back part 2) by the first bend promoting part 41 and the second bend promoting part 42. Is possible.

Drawing 4 is a figure showing other examples of the flat back part of this embodiment, and is a figure showing typically the flat back part before assembling the catching tool main part by a front view.
As shown in FIG. 4, the palm portion 26 of the flat back portion 2 includes a second catching region C2. The second catching region C2 is between the line segment connecting the second vertex P2 and the first vertex P1, the line segment connecting the first vertex P1 and the fourth vertex P4, and the fourth vertex P4 and the fifth vertex P5. This is a substantially rectangular area defined by the edge of the flat back portion 2 (that is, the hand insertion edge 27) and a line segment connecting the fifth vertex P5 and the second vertex P2. Area of the second catching area C2, for example, when it for a typical adult baseball glove on the ^market, is 120cm ² ~145cm 2.

In the example shown in FIG. 4, the first bend promoting portion 41 of the bend promoting portion 4 includes a line segment connecting the second vertex P2 and the fifth vertex P5 in the first region A1 (see FIG. 2), Located in a substantially triangular area A1 ′ defined by the edge 28 of the flat back portion 2 between the fifth vertex P5 and the eighth vertex P8 and the line segment connecting the eighth vertex P8 and the second vertex P2. ing. Further, the second bending promoting portion 42 of the bending promoting portion 4 includes the edge 29 of the flat back portion 2 between the first vertex P1 and the sixth vertex P6, the sixth vertex P6, and the second portion of the second region A2. It is located within a substantially triangular area A2 ′ defined by a line segment connecting the four vertices P4 and a line segment connecting the fourth vertex P4 and the first vertex P1. And the bending promotion part 4 is not substantially formed in the 2nd catching area | region C2. In the example shown in FIG. 4, the fact that the bending promoting portion 4 is “not substantially formed” in the second catching region C2 means that in the second catching region C2, as in the example shown in FIG. This means that not only the case where the bending promoting portion 4 does not enter at all but also the case where the bending promoting portion 4 slightly enters due to manufacturing variation or the like is permitted. Specifically, even if the bending promoting portion 4 slightly enters the second catching region C2, if the area of the portion is less than 5% of the total area of the second catching region C2, the bend promoting portion 4 can be regarded as not being formed in the second catching region C2.
In the flat back part 2 shown in FIG. 4, since the 2nd catching area C2 is wider than the 1st catching area C1, it is possible to ensure a more sufficient catching area from the beginning. Therefore, in the case of the ball catching device 100 having the flat back portion 2 shown in FIG. 4, it is more suitable as a baseball glove for a player who wants to secure a wider ball catching area or a softball glove with a large ball.

Hereinafter, the result of evaluating the bend promoting effect by the bend promoting portion 4 by numerical analysis will be described. In numerical analysis, an eigenvalue analysis is performed by a finite element method using an analysis model that simulates a flat back portion that does not have the bending propulsion unit 4, and the strain when the ball catcher (flat back portion) is closed in a predetermined direction. The site where the size of the area was increased was examined. As setting conditions for the analysis model, the elastic modulus and thickness of the flat back were 50 MPa and 1.5 mm, respectively.
FIG. 5 is a diagram showing the results of the above numerical analysis. In FIG. 5, the color intensity is proportional to the magnitude of the strain. That is, the dark part corresponds to the part where the strain increases when the catcher is closed. Further, in FIG. 5, the edge is displayed with a broken line at a portion where the edge cannot be identified because it is white. From the results shown in FIG. 5, strain is found near the edge of the hand insertion edge 27 on the little finger 25 side and near the edge between the base of the index finger 22 and the base of the thumb 21. It was found that there was a large site.
FIG. 6 is a diagram showing a portion where the strain is relatively large in FIG. 5 superimposed on FIG. Specifically, FIG. 6 is a diagram in which boundaries B1 and B2 of parts where the magnitude of the strain is 40% or more of the maximum strain are drawn on FIG. As can be seen from FIG. 6, the portion having a large strain is located approximately in the first region A1 and the second region A2. The first bending promotion portion 41 is located in the region surrounded by the boundary B1 in the first region A1, and the second bending promotion portion 42 is located in the region surrounded by the boundary B2 in the second region A2. It is formed as follows.
Thus, it is considered that the bendability of the ball catching tool can be improved by forming the first bend promoting portion 41 and the second bend promoting portion 42 corresponding to the portion where the strain increases.

Next, the result of evaluating the influence on the bendability when the position and shape of the bend promoting portion 4 are changed will be described.
The analysis model used in this evaluation is an analysis model shown in FIG. 5 that does not include the bending promotion part 4 as a basic analysis model, and the bending promotion part 4 having a different position and shape is formed in the basic analysis model. In addition, the bending promotion part 4 of each analysis model is formed in a pseudo manner by locally setting a portion having a small elastic modulus at a predetermined portion of the basic analysis model. The areas of the first bend promoting portion 41 and the second bend promoting portion 42 were set to be the same for all analysis models.
The influence of the bend promoting part 4 on the bendability was evaluated based on the rigidity ratio of each analysis model with respect to the basic analysis model for a predetermined closing direction of the ball catcher (flat back part).
The stiffness ratio is expressed by the following equation (1) when the stiffness of the analysis model to be evaluated is K _new , the natural frequency is f _new , the stiffness of the basic analysis model is K _ref , and the natural frequency is f _ref. It is an index to be expressed.
Rigidity ratio = (K _new / K _ref ) ^1/2 = (f _new / f _ref ) (1)
The smaller the value of the rigidity ratio, the higher the flexibility.

7 and 8 are schematic diagrams for explaining each analysis model used in the above numerical analysis. Specifically, FIG. 7 and FIG. 8 show the bending promoting part 4 set in the analysis model corresponding to the front view of the flat back part in order to make the position and shape of the bending promoting part 4 easy to understand. FIG.
FIG. 7A shows a conventional flat back portion (basic analysis model) that does not include the bending promoting portion 4. FIG.7 (b) shows the flat back part which comprises only the 2nd bending promotion part 42 of this embodiment shown in FIG.2 (b). Although FIG. 7C includes the second bending promotion portion 42 ′ having the same shape as that of the present embodiment, the second bending promotion portion 42 ′ is located within the second region A2 and the second bending promotion portion 42 ′ is formed. The flat back part of the reference example remove | deviated from the conditions that part 42 'is not substantially formed in the 1st catching area | region C1 is shown. FIG. 7D includes the second bend promoting portion 42 ′ having the same shape as that of the present embodiment, but deviates from the condition that the entire second bend promoting portion 42 ′ is located in the second region A2. The flat back part of a reference example is shown. FIG.7 (e) shows the flat back part which comprises only the 2nd bending promotion part 42 of a shape different from this embodiment. FIG. 7 (f) shows a reference example that is provided with the second bend promoting portion 42 ′ but is out of the condition that the second bend promoting portion 42 ′ is not substantially formed in the first catching region C1. The flat back is shown.
FIG. 8A shows a conventional flat back portion (basic analysis model) that does not include the bending promoting portion 4. FIG.8 (b) shows the flat back part which comprises only the 1st bending promotion part 41 of this embodiment shown in FIG.2 (b). FIG. 8C includes the first bending promoting portion 41 ′ having the same shape as that of the present embodiment, but the entire first bending promoting portion 41 ′ is located in the first region A1 and the first bending promoting portion is included. The flat back part of the reference example remove | deviated from conditions that part 41 'is not substantially formed in the 1st catching area | region C1 is shown. FIG. 8D includes the first bend promoting portion 41 ′ having the same shape as that of the present embodiment, but deviates from the condition that the entire first bend promoting portion 42 ′ is located in the first region A1. The flat back part of a reference example is shown. FIG. 8E shows a flat back portion including only the first bending promoting portion 41 having a shape different from that of the present embodiment.
In the above numerical analysis, the rigidity ratio was also evaluated for an analysis model that simulates the flat back portion 2 including both the first bend promoting portion 41 and the second bend promoting portion 42 of the present embodiment.

  FIG. 9 is a diagram showing the results of the numerical analysis. Fig.9 (a) shows the rigidity ratio computed about each flat back part shown in FIG. (A) to (f) shown on the horizontal axis of FIG. 9A correspond to the flat back portions of FIGS. 7A to 7F, respectively. Moreover, FIG.9 (b) shows the rigidity ratio computed about each flat back part shown in FIG. (A) to (e) shown on the horizontal axis of FIG. 9 (b) correspond to the flat back portions of (a) to (e) of FIG. 8, respectively. Further, No. 1 in FIG. 1 shows the rigidity ratio calculated about the flat back part shown to Fig.7 (a) and Fig.8 (a). In FIG. 2 shows the rigidity ratio calculated about the flat back part 2 which comprises both the 1st bending promotion part 41 and the 2nd bending promotion part 42 of this embodiment. In FIG. 3 shows the rigidity ratio calculated about the flat back part shown in FIG.8 (b). In FIG. 4 shows the rigidity ratio calculated about the flat back part shown in FIG.7 (b).

As shown in FIG. 9 (a), if the flat back portion 2 ((b) and (e) of FIG. 9 (a)) having the second bending promoting portion 42 included in the scope of the present invention is used, It was found that the rigidity ratio was smaller than when using the flat back part of No. 1 or the flat back part of the reference example. That is, it has been found that providing the second bending promoting portion 42 increases the flexibility. In particular, the rigidity ratio shown in (b) of FIG. 9 (a) of the flat back part 2 is smaller than the rigidity ratio shown in (e) of FIG. It shows that a shape whose width gradually decreases as it goes to, in other words, a shape whose width becomes wider toward the edge 29 side of the flat back portion between the first vertex P1 and the sixth vertex P6 is effective. . This is considered to be because the area where the second bend promoting portion 42 overlaps with a portion having a large strain shown in FIG. 5 becomes larger by forming the second bend promoting portion 42 in such a shape.
Further, as shown in FIG. 9 (b), if the flat back portion 2 ((b) and (e) of FIG. 9 (b)) having the first bending promoting portion 41 included in the scope of the present invention is used. 9B, it was found that the rigidity ratio is smaller than in the case of using the conventional flat back portion or the flat back portion of the reference example except for the flat back portion of FIG. 9B. That is, it has been found that providing the first bending promoting portion 41 increases the flexibility. In particular, the rigidity ratio shown in (b) of FIG. 6B among the flat back part 2 is smaller than the rigidity ratio shown in (e) of FIG. It shows that a shape whose width gradually decreases as it goes to, that is, a shape whose width becomes wider toward the edge 28 side of the flat back portion 2 between the fifth vertex P5 and the eighth vertex P8 is effective. Yes. Similarly to the second bending promotion portion 42, by forming the first bending promotion portion 41 in such a shape, an area where the first bending promotion portion 41 overlaps with a portion having a large strain shown in FIG. 5 becomes larger. This is probably because of this. From the viewpoint of flexibility, it is also effective to use the flat back portion of the reference example of FIG. 9B (c), but this flat back portion is as shown in FIG. 8C. In addition, since the entire first bending promoting portion 42 ′ is formed in the first ball catching region C 1, the first ball catching region C 1 is crushed and is easily bent. That is, although flexibility is improved, a sufficient catching area cannot be secured.
Furthermore, as shown in FIG. 9C, both the flat back part 2 having only the first bend promoting part 41 and the flat back part 2 having only the second bend promoting part 42 are used. It has been found that the use of the flat back portion 2 having the above is preferable in that the rigidity ratio is further reduced (flexibility is increased).

In addition, although the description about the detail of an evaluation result is omitted, even when using the flat back part 2 as shown in FIG. 3, compared with the case where the conventional flat back part and the flat back part of a reference example are used. It was confirmed that the stiffness ratio was small (flexibility increased).
Further, as the setting conditions of the analysis model, even when the elastic modulus and thickness of the flat back are changed within the range used for a general adult grab, the portion where the strain becomes large does not change so much, and the first region A1. And it has confirmed that it was settled in the range of 2nd field A2.

  As described above, according to the ball catching tool 100 according to the present embodiment, it is possible to secure a sufficient ball catching area from the beginning and obtain sufficient flexibility.

FIG. 10 is a diagram for explaining the effect of using the expansion / contraction member 5 for the bending promoting portion 4 provided in the flat back portion 2. FIG. 10A shows the closing operation of the ball catching tool when the flat back portion 2 ′ not including the bending promoting portion 4 (expandable member 5) of the present embodiment is used, and FIG. The closing operation of the ball catching tool when the flat back portion 2 including the bending promoting portion 4 (expandable member 5) is used will be described.
As shown in FIG. 10 (a), in the case of the conventional flat back part 2 ′, when closing the ball catching tool, the length of the flat back part 2 arranged outside the catching surface part 1 (back of the hand) is set. Since the flat back portion 2 and the catching surface portion 1 are bent toward the catching surface portion 1 as a reference, wrinkles are likely to occur in the catching surface portion 1 arranged on the inner side.
On the other hand, as shown in FIG. 10 (b), in the case of the flat back portion 2 of the present embodiment, when the ball catching tool is closed, the expansion / contraction member 5 of the bending promoting portion 4 extends so that the flat back portion 2 Since the length is increased, the advantage that the catching surface portion 1 is less likely to be wrinkled is obtained.
That is, as in the present embodiment, if the bending promoting portion 4 including the elastic member 5 is used, sufficient flexibility can be obtained from the beginning, and at the same time, the effect that the catching surface portion 1 is hardly wrinkled can be obtained. Is also possible.

As shown in FIG. 11, the ball catching tool 100 according to this embodiment includes a ball catching tool body 10 and a web 6 connected to the ball catching tool body 10. In the rear view, the catching tool main body 10 and the web 6 have a substantially L-shaped gap, and are connected by a string-like member 7 disposed in the substantially L-shaped gap. Specifically, the width of the gap along the substantially L-shaped vertical side and the width of the gap along the substantially L-shaped horizontal side have substantially the same dimensions. A string-like member 7 is stretched over the side at substantially the same pitch.
As described above, in the ball catching device 100 according to the present embodiment, the ball catching device main body 10 and the web 6 have a substantially L-shaped gap, and the string is arranged in the substantially L-shaped gap. Since it is connected by the member 7, it is possible to further enhance the flexibility from the beginning as compared with a ball catching device including a conventional ball catching device main body and a web that are not configured as described above. That is, only the string-like member 7 that is easily bent is disposed in the substantially L-shaped gap, and when the catching tool body 10 is closed, the catching tool body 10 and the web 6 do not easily interfere with each other. It is possible to improve flexibility.
In order to further improve the flexibility, it is preferable to expand the window 8 (opening located above the back pad 31) shown in FIG. Specifically, as shown by a broken line in FIG. 11, the window portion so that the distance between the edge (helical leather) of the window portion 8 and the portion along the substantially L-shaped lateral side of the protector body 10 is shortened. It is considered that the flexibility can be further enhanced by expanding 8.

In the present embodiment, the description has been made on the condition that the bending promoting portion 4 is not substantially formed in the first catching region C1, but the present invention is not necessarily limited to this, and FIG. It may be configured as shown.
That is, as shown in FIG. 12, the bending promoting part 4 is located on the inner side of the flat back part 2 from the position on the edge 28 of the flat back part 2 between the fifth vertex P5 and the eighth vertex P8 in the first region A1.

At least one of the second bend-promoting portions 42 having a shape extending toward the top, and the width of each of the first bend-promoting portions 41 and the second bend-promoting portions 42 increases toward the inside of the flat back portion 2. Even if the bending promoting portion 4 is formed in the first catching region C1 as long as the shape gradually narrows, it is possible to improve the flexibility from the beginning compared to the conventional case, A relatively wide catching area can be secured.

In the present embodiment, the example in which the first bend promoting portion 41 and the second bend promoting portion 42 are formed as the bend promoting portion 4 is described. However, the first bend promoting portion 41 and the second bend promoting portion are described. Only one of the portions 42 may be formed, or a plurality of first bending promotion portions 41 and / or a plurality of second bending promotion portions may be formed.
