Description

  The present invention relates to a wrist or finger holding device used for golf or medical use, and in particular, in a golf swing (a series of operations from an address to a finish), an unnecessary movement of a wrist which is an obstacle to a swing is suppressed. And a wrist holding device.

  Conventionally, the angle of the wrist during a golf swing has been known to be very important. This is because, in golf, the grip is a connecting portion between the player and the club, and the angle of the wrist of the grip and the direction of the back of the hand are directly related to the direction of the club face. In golf, vertical movement of the wrist is permitted, but unnecessary lateral movement is prohibited. When the wrist moves in the lateral direction, the shaft falls down in the lateral direction, and the direction of the face of the club changes. At this time, there is no problem if the lateral movement of the wrist is within a certain range, but if it exceeds the certain range (that is, if the angle of the wrist is out of the certain range), it leads to left and right missed shots. Would. Here, the vertical direction is a direction substantially parallel to the palm, and the horizontal direction is a direction substantially perpendicular to the palm.

  The ideal golf swing has been discussed regardless of the east and west of the world. For example, in a golf game, it is desirable to accurately swing a golf club and hit a ball, and perform this accurate swing. It is important to note that starting with the correct grip, ending with the correct address, backswing (takeback), top, and the correct impact, follow-through (finish), What is ultimately important is the formation of an accurate impact that determines the direction of the ball and the distance it travels, not only by gripping the golf club accurately, but also from the address to the top. Performing a backswing is particularly important in that it creates the exact impact of a precise swing, and When performing a backswing from the address of the above, so as to maintain the above-mentioned good inclination state of the back of the hand, that is, during the backswing, the upper part from the back of the hand or the wrist to the elbow keeps the inclination of the angle. A method for achieving a state is generally regarded as a method for performing an ideal backswing ”(Patent Document 1).

  Based on this conventional technique, various wrist fixing devices for keeping the back of the hand at a predetermined angle during the backswing have been proposed or marketed. The golf backswing correction aid of Patent Document 1 described above does not disclose because it has different components from the invention of the present application, but it also includes, for example, a glove support band 1 having a shape capable of supporting gloves and a back of the hand. And a back support band 3 arranged so that the surface on the side close to the wrist is opposite to the back surface of the hand support band 1, and the hand support band 1. And the back of the hand 3 are fixedly connected to the back of the hand and the back of the hand, respectively, and the fixing bands 2 and 4 are connected to each other, and the back of the hand 1 and the back of the hand 3 are connected to each other. A center pin 5, each end of which is rotatably coupled to the wrist support band 1 and the back support band 3, respectively, so as to be rotatable in the direction of the index finger; The rotation operation In order to rotate and fix the back support band 3 to the front side or the back side of the back support band 1, the middle portion is screwed to the back support band 3, and one end side is connected to the back support band 1. There is a wrist fixing band for golf including a bending angle adjusting pin 6 which is slidably connected (Patent Document 2). Note that the “angle of the back of the hand” expressed in the above-described prior art is synonymous with the “angle of the wrist” of the present application.

In addition, the following four types of fixtures are found as conventional commercial products.
(A) A type in which the back of the wrist is fixed at a fixed angle with a hard plastic plate.
(B) The upper part of the wrist is fixed at a fixed angle with a hard plastic plate, two soft thin plastic plates are extended from the center of the back of the hand to the fingertips, and are addressed to the fingers. A type that strengthens the muscles of the fingers when gripping. The hard plastic plate and the soft thin plastic plate are inserted in the glove.
(C) In the above (A) and (B), the wrist on the side leading the golf club (for example, the left wrist in the case of right-handed) is fixed, whereas the wrist on the opposite side (for example, the right wrist) is fixed. The right side of the right wrist) is fixed at a certain angle with hard plastic.
(D) The hands (that is, the left and right wrists and forearms) are connected by a connecting device such as handcuffs having a fan-shaped goniometer at the center, and swinging while maintaining the angle of both hands (forearms) made in advance. Type to do.

Japanese Patent No. 2855241 JP-A-9-117540

  Patent Literature 1 is a technical idea that the angle of the wrist formed at the time of address is completely fixed during the swing operation, and the golf wrist fixing band of Patent Literature 2 and the four types of commercially available products are patented. This is based on the technical idea of Document 1. In contrast, modern golf theory discusses the following techniques.

  In a golf swing, a simple movement of the body is required, but a delicate movement is actually required due to a human body structure. Here, reference is made to finger, wrist, and forearm movements, and not to other body movements.

  First, in the movement of gripping with a finger, the first joint (MP joint), the second joint (PIP joint), and the third joint (DIP joint) bend in the palm side (lateral direction as viewed from the thumb or little finger direction). . For this reason, in the above-mentioned commercial product (B), the plastic plate addressed to the fingertip becomes an obstacle, and stable grip is impossible. Also, the movement of the wrist changes subtly in the above-mentioned address, backswing (takeback), top, impact, and follow-through (finish). In practice, the angle of the wrist changes depending on the strength of the grip strength to grip. For example, in the state of hanging down with no hand, the dorsiflexion is slight (the angle of the wrist is about 15 degrees), and in the state of gripping the club lightly, the dorsiflexion is moderate (20 degrees). At the top position, the three fingers (middle finger) and the four fingers (ring finger) are strongly gripped, and the wrist angle is substantially straight at about 10 degrees. In addition, at the time of impact, the third finger, the fourth finger, and the fifth finger (the little finger) are gripped more strongly, so that they are in a slightly bent position, and take a slight dorsiflexion from the end of the follow-through to the finish.

  In addition, the forearm also has pronation and supination movements. Raise your hand to the front and extend your finger to call the middle position. When the player grips with the address, the player is in a slightly pronation position. From this state, the user pushes up the left shoulder in the direction of the thumb (thumb), and takes a slightly pronation position from the middle position. This is the top.

  From the top to just before the impact (that is, downswing), the player holds the middle position and makes an impact at a stretch from the end of the downswing (that is, release). Immediately after release, bend the left elbow and raise it in the thumb direction (fold the elbow in). In this way, finish is performed using body rotation from follow. At the finish, the wrist again assumes a slight dorsiflexion.

  As described above, in the natural body movement during a golf swing, the angle of the wrist is not fixed and changes slightly, so "unnecessary movement that is harmful to the golf swing is limited, but the natural body movement is limited. "No," is the theory of modern golf.

  However, in the technique of Patent Document 2, the grip is not stable because the flat band is attached to the back of the hand and the fixed band is wound around the palm, and the forearm is also easily rotated and very unstable. It is. In addition, there is a problem that a sense of incongruity is generated at the time of mounting because of having pins and screws. Further, among the above four types of commercially available products, the types (A) and (C) use a hard plastic from the back of the hand to the wrist, so that there is an uncomfortable feeling when wearing and when using. In the case of the type (B), since a plate-shaped object is addressed from the wrist to the fingertip, it is impossible to grip firmly when gripping due to the human body structure. The (D) type has a problem that it is very difficult to swing because both hands are connected by a handcuff-like connecting tool.

  The present invention has been made in view of the above-mentioned problems of the prior art, and uses a flexible elastic coil bone and a thin plastic sheet having some elasticity without using a hard member. It is intended to provide a wrist holder that can restrict unnecessary movement of a wrist in a golf swing and can swing naturally with a natural movement in a golf swing.

  For this reason, the wrist holding device according to the present invention has a band-shaped hook-and-loop fastener, a wristband portion detachably attached to the wrist, and a band-shaped hook-and-loop fastener, and includes a first joint and a second joint of the middle finger. A wrist holder comprising a finger band portion detachably mounted between the wrist band portion and a connecting band portion connecting the wrist band portion and the finger band portion, wherein the wrist band portion, the finger band portion, The connection band portion is integrally formed of an elastic material, and a coil bone and a plastic thin plate are inserted by being superimposed along the longitudinal direction of the connection band portion, and the wrist holder When attached to the wrist, the coil bone is inserted so that the upper end is located below the second joint of the middle finger, and the lower end is located below the center of the ulnar head of the wrist. Polymerized with the coil bone The main feature of the plastic thin plate is that its upper end is located below the first joint of the middle finger and its lower end is inserted above the center of the ulna head. . Note that the coil bone is a spring having a shape in which a coil spring is crushed flat, and is sometimes referred to as a spiral bone.

  According to the wrist holding device according to the present invention, during a series of swinging operations from an address to an impact to a finish in golf, while restricting unnecessary movements of the wrist leading to a missed shot (in other words, in a missed shot, While maintaining the angle of the wrist in a range where it cannot be connected), there is an excellent effect that it is possible to swing with a natural movement without strain on the body.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings, but it is needless to say that the present invention is not limited to the embodiments. FIG. 1 is an explanatory view showing a state in which the wrist holder according to the present invention is mounted on a wrist, and is a view as seen from the back of the hand. FIG. 2 is a plan view of the wrist holder of FIG. FIG. 3 is an explanatory view showing a state in which the wrist holder according to the present invention is mounted, and is a view as seen from the thumb side of the hand.

  As shown in FIGS. 1 to 3, the wrist holder 1 according to the present invention includes a wristband portion 3 detachably attached to a left wrist W, and a first joint M and a second joint P of a left middle finger F3. A main body 2 integrally formed with a finger band portion 4 detachably mounted therebetween, a connecting band portion 5 connecting the wrist band portion 3 and the finger band portion 4, and sewn to the wrist band portion 3. A belt-shaped hook-and-loop fastener 3a and a band-shaped hook-and-loop fastener 4a sewn to the finger band portion 4. Further, along the longitudinal direction of the connecting band portion 5, the coil bone 6 and the plastic thin plate 7 overlap. And then interpolated. Further, on the upper surface of the wristband portion 3, a surface fastener 3b to which the other end of the surface fastener 3a can be connected is sewn. On the upper surface of the finger band 4, a surface fastener 4b to which the other end of the surface fastener 4a can be connected is attached. Hereinafter, in the present embodiment, the left wrist W is described as a wrist W, and the left middle finger F3 is described as a middle finger F3. In addition, the stitches that have been joined at each part are not shown.

  The main body 2 is formed of a nylon jersey having elasticity and some elasticity, and its peripheral edge is bordered by a reinforcing material. This nylon jersey is a material that is also used for wet suits and the like, and has a very good feeling of being worn on the skin. In golf, there is no discomfort during addressing or swinging. The main body 2 can be replaced with another material having elasticity and some elasticity, for example, a polyester jersey.

  The wristband portion 3 is formed to have a predetermined length and a predetermined width for suppressing unnecessary movement of the wrist W. In this embodiment, as shown in FIG. 2, the ulnar head U is formed bilaterally symmetrically, and as shown in FIG. As shown in FIG. 2, one end of an elastic band-shaped hook-and-loop fastener 3a is sewn on the upper left side of the wrist band portion 3. The hook-and-loop fastener 3a has a mating portion on the entire back surface. Further, a hook-and-loop fastener 3b is sewn in a range from the center of the upper surface of the wristband portion 3 to the right side so that the joint portion faces the front side. With such a configuration, after the wristband portion 3 is put on the wrist, the hook-and-loop fastener 3a is wound around the wrist according to the thickness of the wrist while pulling the hook-and-loop fastener 3a with an appropriate force, and then the hook-and-loop fastener 3a is put in place. By connecting to the hook-and-loop fastener 3b, the wristband portion 3 is securely wound around the wrist, and the angle of the wrist is maintained.

  The finger band portion 4 is formed to have a length that can be wound around the middle finger F3, and has a width from the first joint M to the second joint P of the middle finger F3. Similarly to the wrist band 3, one end of an elastic band-shaped hook-and-loop fastener 4a is sewn on the upper left side of the finger band 4. The hook-and-loop fastener 4a has a mating portion on the entire back surface. A hook-and-loop fastener 4b is sewn at the center of the upper surface of the finger band portion 4 so that the mating portion faces the front side. With this configuration, after the finger band portion 4 is wound around the middle finger F3, the hook-and-loop fastener 4a is wound around the middle finger F3 according to the thickness of the middle finger F3 while pulling the hook-and-loop fastener 4a with an appropriate force. The finger band part 4 is firmly wound around the middle finger F3 by combining the right place with the hook-and-loop fastener 4b. Since the hook-and-loop fastener 4a has elasticity, the degree of tightening at the time of winding can be freely adjusted.

  The connecting band portion 5 is formed by integrally connecting the finger band portion 4 and the wrist band portion 2. One end of the connecting band portion 5 is narrowed from the finger band portion 5 toward the wrist band portion 3, and then the connecting band portion 5 is widened. Is formed. Along the longitudinal direction of this connecting band portion 5 (vertical direction in FIG. 1), a coil bone 6 and a plastic thin plate 7 are superposed and inserted. As shown in FIG. 1, when the wrist holder 1 is attached to the wrist W, the upper end of the coil bone 6 is located below the second joint P of the middle finger F3, and the lower end is located below the center of the ulnar head U. It is interpolated to be located on the side. The plastic thin plate 7 superposed on the coil bone 6 is inserted so that the upper end is located below the first joint M of the middle finger F3 and the lower end is located above the center of the ulnar head U. In the present embodiment, the coil bone 6 is inserted so that the upper end is located about 2 cm below the second joint P of the middle finger F3, and the lower end is located about 2 cm below the center of the ulnar head U. The plastic thin plate 7 superposed on the coil bone 6 has an upper end located approximately 1.5 cm below the first joint M of the middle finger F3, and a lower end located approximately 1.5 cm above the center of the ulnar head U. It is interpolated to be located. The width of each of the coil bone 6 and the thin plate 7 is about 1 cm. After the coil bone 6 and the thin piece 7 are superimposed and inserted into the main body 2, the front and back surfaces of the main body 2 at the periphery of the coil bone 6 having a length longer than the thin plate 7 are applied with a reinforcing patch 8. Through the interposition, the coil bone 6 and the thin piece 7 are fixedly inserted at a predetermined position. Since the thin plate 7 is made of thermoplastic plastic, it can be formed at a predetermined fixed angle by heating.

  As described above, when the wrist holder 1 according to the present invention is mounted on the wrist W, from the lower side of the second joint P of the middle finger F3 to the lower side of the ulnar head U of the joint of the wrist W via the first joint M. When the grip of the golf club is gripped, the middle finger F3 is slightly biased toward the back of the wrist by the coil bone 6, but is vertically and horizontally movable. To hold the club during a series of operations of addressing, takeback, and impact. In addition, a plastic thin plate 7 having flexibility and some elasticity is inserted in a range from the lower side of the first joint M of the middle finger F3 to the lower side of the ulnar head U, and is mounted on the wrist W. By winding and fixing the elastic band-shaped hook-and-loop fastener 3a from above the wristband part 3, the angle of the joint of the wrist W can be stably held within a certain range, and the wrist is unnecessary. Movement can be restricted. In addition, since the main body 2 is made of a material such as nylon jersey having elasticity and elasticity, it has a very good fit at the time of mounting and has no obstacle during swing. Further, since the middle finger F3 is slightly biased toward the back of the wrist W by the coil bone 6, when the grip of the club is gripped, the middle finger F3 is bent toward the palm side opposite to the biasing direction, so that the middle finger F3 is bent. It also has the effect of strengthening muscle strength. As described above, the wrist holder according to the present invention has a very excellent effect as compared with the related art.

  Further, as shown in FIG. 3, a normal address can be created by keeping the wrist angle (medium dorsiflexion) of the left hand at 20 ° to 25 ° at the address, so that the wrist W can be unnecessarily laterally moved. By not using it, the club surface is squared from the address to the impact through the top, and an accurate impact zone is obtained, and a long impact is obtained. Also, by using the coil bone 6 and the plastic thin plate 7 with a predetermined length and width, a natural and natural return of the wrist can be obtained from the impact to the finish. By using this product, you can hit the ball with a body turn without operating the club with your own power. Further, since the club can be grasped with an accurate grip, the club face can be adjusted more squarely with respect to the ball.

  In the above embodiment, the left wrist is described as an example. However, the wrist holder according to the present invention can be easily modified to the right wrist. Since the right wrist must be bent to the back side to the upper side to some extent, the width of the wristband portion 2 shown in the above embodiment may be narrowed so that the right wrist can be bent to a predetermined angle. .

  In addition, the wrist holder according to the present invention can be used not only as a wrist holder as described above, but also as a finger holder if the hook-and-loop fastener attached to the finger band is securely wound around the finger. Can be used. Such finger holders and wrist holders can be used not only for sports such as golf, but also for medical purposes, for example, when holding fingers and wrists for treatment and rehabilitation. In addition, since a finger or a wrist can be held, it goes without saying that it can be used as a correction tool.

FIG. 3 is an explanatory view showing a state in which the wrist holder according to the present invention is mounted. It is a top view of the wrist holder of FIG. FIG. 3 is an explanatory view showing a state in which the wrist holder according to the present invention is mounted.
