Description

  The present invention relates to a racquet grip cross-sectional dimension adjusting member for adjusting a lateral dimension and a vertical dimension of a grip section in a racket having a frame surrounding a ball striking face and a grip for gripping attached to the frame, and It relates to the racket used.

  As shown in Patent Document 1, a tennis racket includes a frame surrounding a ball striking surface, a long bar-shaped grip for gripping, and a grip formed by winding a grip tape on an outer peripheral surface of a grip body having a substantially octagonal cross section. have. The grips can be roughly divided into Continental grips, Eastern grips and Western grips. Continental grip is a way of gripping a racket in the same way as a kitchen knife. The Eastern grip is a gripping method in which the user holds the racket with the left hand and the right hand against the racket striking surface and moves the right hand to the grip as it is. On the other hand, Western grip is a method of gripping a racket on the ground and holding the grip straight from above, and is generally regarded as a method of gripping a racket for soft tennis. In hard tennis, there are hitting methods such as forehand stroke, backhand stroke, volley, and smash, and it is necessary to change the grip gripping method according to each hitting method. It is necessary to do better. For this reason, as a shape of a grip section, it is desirable that it is a shape that can instantly recognize that it is an appropriate gripping method.

  In the case of hard tennis, it is basically assumed that the hitting surface of the racket is substantially perpendicular to the ground when hitting, and this is said to stabilize the hitting ball height. In the case of an Eastern grip, it is said that the palm is parallel to the ball striking surface, so that the grip is easy to stabilize and it is close to the feeling of hitting the ball with the palm. Therefore, in the case of hard tennis, the Eastern grip, whose grip position is easy to stabilize, is suitable for beginners and amateur players with little practice. When using an Eastern grip, the cross-sectional dimension of the grip is the dimension between a pair of right-angled surfaces perpendicular to the racket's ball striking surface (lateral dimension). It is considered that 1.15 times or more is desirable with respect to the dimension (vertical dimension) between them.

  On the other hand, in the case of hard tennis, it is known that by changing the grip of the racket from the Eastern grip to the Western grip, it is easy to apply force when hitting the ball and to easily rotate the ball. Therefore, for veteran players with a lot of practice, the power of hitting balls can be increased, so the use of semi-Western grips, which are intermediate between Eastern grips and Western grips, is increasing. For veteran players who have a lot of practice, the ball striking surface can be kept perpendicular to the ground by years of practice, even if the grip is changed. In the case of using a semi-western grip, it is preferred that the ratio of the horizontal dimension and the vertical dimension of the grip be smaller than that of the Eastern grip so that the grip can be easily changed. Many professional top players use semi-Western grips or Western grips with rackets that have a small ratio between the horizontal and vertical dimensions of the grip, making them popular with rackets used by such top players. Gathered. For this reason, in a tennis racket sold in recent years, the ratio between the horizontal dimension and the vertical dimension of the grip is as small as about 1.13 to 1.14.

  However, if the ratio between the horizontal dimension and the vertical dimension of the grip is small in this way, for amateur players with little practice, whether or not they are gripping in a gripping method suitable for the hitting method. Since it is difficult to recognize, there is a case where the striking surface is slightly displaced while changing the grip. As a result, since the ball striking surface is not stable, the flying height of the ball cannot be stabilized, and it is easy to lead to the mistake that the ball does not exceed the net or the base line is exceeded. On the other hand, it is easier for some of the veteran players who use semi-Western grips or Western grips to change the ratio of the horizontal dimension to the vertical dimension from 1.13 to 1.14. However, since a racket having a grip cross-sectional dimension suitable for preference is not sold, it is necessary to use a racket that is slightly deviated from the desired shape. In this way, although the optimal grip cross-sectional shape is different due to differences in the level of tennis technology, the purpose of use such as singles and doubles, the difference in play style, etc., commercially available rackets have a grip cross-sectional shape. Therefore, it has been difficult to accurately meet the various requirements of many players.

JP 2012-115392 A

  The present invention is intended to solve the above problems, and can accurately meet the demands of many players with different years of experience, play styles, etc., against a commercially available racket with a uniform grip cross-sectional dimension. An object is to provide a grip cross-sectional dimension adjusting member and a racket for a racket.

In order to achieve the above object, the constitutional feature of the present invention is that the grip tape is wound around the outer periphery of the frame surrounding the ball striking face and the long rectangular bar-shaped grip body attached to the frame. A grip cross-sectional dimension adjusting member used for a racket having a grip formed thereon, and a pair of right-angled surfaces facing each other at right angles to the striking surface of the racket of the grip body or facing each other parallel to the striking surface to a length of at least one bending deformable elongated thin plate to fit the length of the pair of the grip body to be pasted superimposed on the entire length in the length direction of the parallel surface side, a pair pasted It is possible to adjust the cross-sectional dimension of the grip only in the direction parallel to the hitting surface on the right-angle surface side or only in the direction perpendicular to the hitting surface on the pair of parallel surfaces . The racket includes hard tennis, soft tennis, badminton and the like. In addition, the right-angle plane and parallel plane of the grip body are usually flat surfaces, but include surfaces with slight irregularities. The overlapping of the grip cross-sectional dimension adjusting member and the attachment to the right-angled surface or parallel surface are preferably performed with an adhesive, but an adhesive can also be used.

  In the present invention configured as described above, a grip cross-sectional dimension adjusting member is attached to a pair of opposing right-angled surfaces that are perpendicular to the hitting surface of the racket of the grip body, so that the direction parallel to the hitting surface can be obtained. The dimension (lateral dimension) of the grip section can be adjusted to be longer. For example, in a hard tennis racket, the lateral dimension is usually longer than the dimension (longitudinal dimension) of the grip section perpendicular to the ball striking surface, but the lateral dimension can be further increased. Therefore, for beginners of hard tennis adopting Eastern grips, the dimension of the surface parallel to the hitting surface of the grip becomes longer, and the palm hits this parallel surface, so that it is gripping with an appropriate grip It is easy to recognize and close to the feeling of hitting the ball with your palm. As a result, according to the present invention, even an amateur player with a small practice amount can easily make the hitting surface of the racket substantially perpendicular to the ground when hitting, thereby stabilizing the hitting ball height. .

  On the other hand, the grip section dimension adjusting member is attached to a pair of opposing parallel planes parallel to the hitting face, thereby adjusting the grip section dimension (vertical dimension) in the direction perpendicular to the hitting face to be longer. In the case of a tennis racket, the vertical dimension can be made longer than the horizontal dimension as opposed to the normal dimension. As a result, it becomes easier for experienced tennis players to grip with Western grips. Also, in rackets such as soft tennis as well as hard tennis, by attaching a grip cross-sectional dimension adjustment member with an appropriate thickness to the right-angle or parallel surface of the grip body, many different years of experience, play styles, etc. It is possible to accurately meet various requirements regarding the grip cross-sectional shape of the player.

  In this invention, it is preferable that the grip cross-sectional dimension adjustment member is bent according to the cross-sectional shape of the bonding surface of a grip main body. The cross-sectional shape of the grip body is usually an octagon with four rectangular corners cut out, but by adjusting the grip cross-sectional dimension adjustment member in advance, even a slightly stiff material can be applied to the grip body. Bonding can be performed easily.

  In the present invention, the grip cross-sectional dimension adjusting member is preferably bent in a curved shape that approximates the cross-sectional shape of the bonding surface of the grip body. As a result, even if the grip cross-sectional dimension adjusting member is a slightly stiff material, it can be easily bonded to the grip body, and it is bent in a curved shape, resulting in a slight difference in the size of the bonding surface. Is also possible.

  In the present invention, the grip cross-sectional dimension adjusting member is preferably made of a material that can be easily cut with a knife. As a result, when there is a slight misalignment when attaching the grip cross-sectional dimension adjusting member or the grip cross-sectional dimension adjusting member protrudes due to a deviation from the grip body, excess protruding parts can be easily removed with a knife. can do.

Another feature of the present invention is a racket having a frame surrounding a ball striking surface and a grip formed by winding a grip tape around an outer peripheral surface of a long rectangular bar-shaped grip body attached to the frame. The length of the grip body is matched with the total length of the grip body to the full length of the pair of right-angle surfaces perpendicular to the ball striking surface of the grip body or the pair of parallel surfaces opposite to each other. A grip cross-sectional dimension adjusting member, which is a long thin plate that can be bent and deformed, is affixed in a superimposed manner , and is parallel to a pair of right-angled ball striking surfaces. That is, the cross-sectional dimension of the grip can be adjusted only in the direction or in the direction perpendicular to the hitting surface on the pair of parallel surfaces . In another feature, the grip cross-sectional dimension adjusting member, which is one or more thin plates, is affixed to the right-angle or parallel plane of the grip body in advance, so that the racket owner matches the purpose of use, play style, etc. By increasing or decreasing the number of dimension adjusting members, it is possible to easily adjust to the desired grip cross-sectional shape.

  In other features, the grip cross-sectional dimension adjusting member is preferably bent in accordance with the cross-sectional shape of the bonding surface of the grip body, or bent in a curved shape that approximates the cross-sectional shape of the bonding surface of the grip body. It is preferable that Furthermore, it is preferable that the material of the grip cross-sectional dimension adjusting member is a material that can be easily cut with a knife.

FIG. 1 is a partially broken front view of a hard tennis racket according to a first embodiment, FIG. 2 is a front view and a plan view of a part of the racket, and FIGS. 3 and 4 are front views and parts of the grip body. It is shown by a sectional view. A hard tennis racket 10 (hereinafter referred to as a racket 10) includes an oval frame 11 and a grip 16.

  The frame 11 is made of an epoxy resin composite material, and is provided with an oval head portion 12 and a shaft portion 13 connected to one end side in the long axis direction and extending in the long axis direction. The shaft portion 13 has a triangular so-called open throat shape in which two rod-like portions extending from both sides sandwiching the major axis of the head portion 12 are integrated on the grip 16 side. However, the shaft portion is not limited to an open throat, but may be a straight rod. The frame 11 is formed by resin integral molding. A string (not shown) is stuck to the head portion 12 in the vertical direction and the horizontal direction, thereby forming a flat hitting surface 14.

  The grip 16 includes a straight rod-shaped grip body 17 made of urethane resin having an octagonal cross section, an end cap 22 attached to the rear end side opposite to the head portion 12 of the grip body 17, a grip body 17 and For example, a grip tape 23 in which an adhesive material is attached to one surface of a polyurethane resin formed in a band shape having a width of 25 mm, for example, is wound around the outer periphery of the end cap 22. The grip body 17 has a pair of opposed parallel surfaces 18 parallel to the ball striking surface 14 and a pair of right-angled surfaces 19 facing each other at right angles to the ball striking surface 14. A boundary portion of the right-angled surface 19 is an inclined surface 21 that is notched with an inclination of approximately 40 ° to 45 ° with respect to the parallel surface 18. For example, the dimension between the right-angled surfaces 19 (lateral dimension) Lh is approximately 33.5 mm, the dimension between the parallel surfaces 18 (vertical dimension) Lv is 29.5 mm, and the ratio Lh / Lv between the two is 1.135. It has become. Commercially available tennis rackets with a ratio of Lh / Lv = 1.13 to 1.14 are mainly used. The grip body 17 is provided with an attachment hole (not shown) that is recessed in the axial direction on the inner end side, and the shaft portion 13 is fitted to the attachment hole on the end portion side and fixed to the shaft portion 13 integrally. . In the first embodiment, a thin plate-like grip cross-sectional dimension adjusting member 25 (hereinafter referred to as a dimension adjusting member) is attached to a pair of right-angled surfaces 19 so as to overlap three thin plates 25a.

  The dimension adjusting member 25 is formed by bending a rectangular long plate having a length corresponding to the entire length of the grip body 17 on both sides in the width direction, and as shown in FIG. It is processed into a trapezoid shape composed of a central portion 26 bent according to the shape of the inclined surface 21 and inclined portions 27 on both sides thereof. Further, both end sides in the longitudinal direction of the dimension adjusting member 25 are inclined portions 28 cut out at an angle of about 60 °. The dimension adjusting member 25 is a rubber elastic body, an elastic body elastomer, a flexible resin material, a resin composite material obtained by mixing wood scraps or fiber scraps with resin, an adhesive tape, etc. It is formed of a material that can be easily cut. In the first embodiment, the dimension adjustment member 25 has a configuration in which three thin plates 25a having a thickness of less than 1 mm are bonded with an adhesive to adjust the dimension, but the lateral dimension between the right-angled surfaces 19 is adjusted. For this purpose, the number of thin plates 25a to be attached is adjusted. As shown in FIG. 4, in the state where the dimension adjusting member 25 is attached to both the right-angled surfaces 19 of the grip body 17, the lateral dimension Lh ′ between the right-angled surfaces is extended to approximately 39 mm, and the ratio Lh ′. / Lv is as large as 1.28. The ratio Lh ′ / Lv is appropriately adjusted to be a value of 1.15 or more according to the player's preference.

Next, a method of using the dimension adjusting member 25 for the grip 16A of the commercially available racket 10 will be described with reference to FIGS.
First, the grip body 17 of the grip 16A (FIG. 6A) and the grip tape 23 wound around the end cap 22 are removed to expose the grip body 17 (FIG. 6B). Next, the dimension adjusting member 25 is arranged on the pair of right angle surfaces 19 side of the entire length of the grip body 17 (FIG. 6C), and the central portions of the three thin plates 25a of the dimension adjusting member 25 are overlapped to form the right angle surface 19. Is attached with an adhesive, and the both sides of the thin plate 25a are overlapped and attached to the inclined surface 21 of the grip body 17 (FIG. 7A). Thereafter, the grip tape 23 is wound again around the grip body 17 and the end cap 22 to complete the attachment of the dimension adjusting member 25 (FIG. 7B).

  Further, the user grasps the grip 16 to confirm the grip feeling. If the dimension is insufficient, the user repeats the above procedure to increase or decrease the number of the thin plates 25a of the dimension adjusting member 25, thereby the grip 16 It is possible to adjust the horizontal dimension of the sensor to the optimum dimension for itself. In the first embodiment, three thin plates 25a are pasted to adjust the dimensions, but the number of thin plates 25a may be two, one, or four or more.

  In the first embodiment, as shown in FIG. 4, the dimension adjusting member 25 is attached to the pair of right-angled surfaces 19 opposite to each other at right angles to the striking surface 14 of the racket 10 of the grip body 17 with an adhesive. The lateral dimension Lh of the grip body 17 in the direction parallel to the ball striking face 14 can be adjusted to a desired length Lh ′. For this reason, particularly when an amateur player of a hard tennis with a small practice amount hits a stroke with an Eastern grip, the palm hits the parallel surface 18 whose dimension parallel to the striking surface 14 of the grip 16 is increased. Makes it easier to recognize if the is properly held. Furthermore, since the player feels like hitting the ball with the palm of the hand, the player can hit the ball more reliably. In addition, when gripping with a continental grip necessary for volley, service, and smashing, an appropriate grip can be obtained by gripping the thumb so that the thumb is parallel to the parallel surface 18 with increased dimensions. As described above, according to the first embodiment, even a beginner or an amateur player with a small amount of practice can easily perform an appropriate grip when hitting, and can perform a stroke or shot with few mistakes.

  In the first embodiment, the dimension adjusting member 25 is bent into a trapezoidal shape in accordance with the cross-sectional shape of the bonding surface of the grip body 17, so that even a slightly stiff material can be bonded to the grip body 17. It becomes possible to carry out easily. Since both ends of the dimension adjustment member 25 in the trapezoidal width direction are aligned vertically, unnecessary irregularities are generated on both sides in the width direction when the dimension adjustment member 25 is attached to the inclined surface 21 side. Is suppressed. Further, since the dimension adjusting member 25 is made of a material that can be easily cut with a knife, the position of the dimension adjusting member 25 due to a slight positional deviation when the dimension adjusting member 25 is attached or a dimension deviation from the grip body 17 is obtained. When there is an overhang or the like, the excess protruding portion can be easily removed with a knife.

Next, a modification of the first embodiment will be described.
As shown in FIG. 8, the dimension adjustment member 25 </ b> A of the modification is bent in a trapezoidal shape in the width direction similarly to the dimension adjustment member 25 of the first embodiment, but has a central portion 26 and inclined portions 27 on both sides thereof. A curved portion 29 is bent in an arc shape between the two. Thus, by bending the dimension adjusting member 25A in a curved shape, the dimension adjusting member 25A can be easily bonded to the grip body 17 even if the material is somewhat stiff, and is bent in a curved shape. Therefore, it is possible to flexibly cope with a slight difference in the size of the bonding surface, that is, the grip size. Moreover, both the case where the dimension adjustment member 25 of the same dimension is stuck on the right angle surface 19 side of the grip body 17 and the case where it is stuck on the parallel surface 18 side as described later are possible.

  Further, as a second modification of the dimension adjusting member 25 of the first embodiment, as shown in FIG. 9, the center portion 26 on the upper side of the stacked thin plates 25a having the same shape is flat only with the central portion and without the inclined portion. The thin plate 25b can be overlapped to form the dimension adjusting member 25B. Thereby, a dimension change surface can be raised and it can change to favorite cross-sectional shape. Similarly, the dimension adjustment member 25A can be superimposed only on the center side.

Next, Example 2 will be described with reference to FIG.
In the second embodiment, instead of the first embodiment, a grip cross-sectional dimension adjusting member 31 in which three thin plates 31 a are bonded to the side of a pair of opposing parallel surfaces 18 parallel to the hitting surface 14 of the grip body 17 is overlaid. It is something that is pasted. The dimension adjusting member 31 is formed by bending a rectangular long plate having a length corresponding to the entire length of the grip body 17 on both sides in the width direction, and as shown in FIG. It is processed into a trapezoid shape composed of a central portion 32 bent according to the shape of the inclined surface 21 and inclined portions 33 on both sides thereof. The dimension adjusting member 31 adjusts the longitudinal dimension Lv of the grip body 17 in the direction perpendicular to the ball striking face 14 so as to be longer than the dimension Lv ′.

  The racket of the second embodiment can be reverse to the conventional racket (Lh> Lv) in which the longitudinal dimension Lv ′ of the grip body 17 is longer than the lateral dimension Lh. In this case, in the conventional racket, the striking surface and the long dimension surface of the grip are parallel to each other, whereas in the racket of Example 2, the striking surface and the long dimension surface of the grip are at right angles. The advantages of such a racket are as follows. When a conventional racket is gripped with a Western grip, the thumb and forefinger will be widened, and a triangular prism-shaped gap will be created at the corner of both fingers and the portion of the grip body 17 where the surface 24 shown in FIG. become. For this reason, it is considered that the forehand stroke, which is considered to occupy an important part in the game, causes instability.

  On the other hand, when a racket having a longitudinal dimension Lv ′ longer than the lateral dimension Lh obtained in Example 2 is gripped with a Western grip, the corner and grip tape shown in FIG. It is considered that the triangular prism-shaped gap formed between the surface of the central portion 32 covered with the surface becomes smaller and the stability of the forehand stroke is increased. As described above, in Example 2, the relationship between the striking surface and the long dimension surface of the grip is rotated by 90 ° with the conventional racket by attaching the dimension adjusting member 31 to the parallel surface 18 while adjusting the thickness. There is also an advantage that the racket can be made according to preference. Such a racket is considered suitable for veteran players who prefer Western grip. In the second embodiment, in the case of a player with a normal hand size, it is preferable to change the cross-sectional shape by selecting a racket having a grip body size smaller than usual, that is, a size Lv, Lh smaller than usual. This makes it easy to obtain a grip cross-sectional shape that is easy to grip. In the second embodiment, it is of course possible to adjust the vertical dimension Lv ′ to be shorter than the horizontal dimension Lh as necessary.

  As described above, in the first and second embodiments, the dimension adjusting members 25, 25A, 25B, and 31 are connected to the right angle surface 19 and the parallel surface 18 of the grip body 17 with respect to a commercially available racket having a uniform grip cross-sectional dimension. By attaching them together, the horizontal and vertical dimensions of the grip section can be easily adjusted, so that it is possible to accurately meet the demands of many players with different years of experience and play styles.

  In the first and second embodiments, the racket for hard tennis is described. However, the present invention is not limited to this, and in the rackets such as soft tennis and badminton, the grips of many players whose use purposes and play styles are different. A similar effect can be obtained in that various demands on size can be accurately met. Moreover, in the said Example 1, 2, although the user of a racket demonstrated the aspect which adjusts a dimension, affixing a dimension adjustment member on a grip main body, the state which affixed the predetermined number of dimension adjustment members to the grip main body previously A product form in which the racket is sold is also conceivable. About such a racket, the user of a racket can perform the dimension adjustment according to a self request | requirement by peeling a dimension adjustment member or overlapping and bonding. In this case, the presence and content of the adjustment member are clarified by displaying the name and the number of adjustment members on a tape stopper or the like that stops the grip tape 23 wound around the grip body 17 on the end side.

  In the first and second embodiments, the dimension adjustment member is bent in a trapezoidal shape or a curved shape in order to facilitate the attachment to the grip body. Or an uneven surface. In the first and second embodiments, the grip body has a straight shape as a whole. Alternatively, the grip body may have a shape that is gradually narrowed near the shaft portion. Furthermore, the shape, dimensions, material, and the like of the tennis grip are not limited to those in the first and second embodiments. In addition, each said Example is an example and can be implemented in various changes in the range which does not deviate from the meaning of this invention.
