DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an array used for strength training, and more particularly to a stick array suitable for conditioning an inner muscle (small muscle group) damaged by exercise or overuse in a sport of swinging an arm.

[0002]

2. Description of the Related Art Although the weight of an array cannot be adjusted stepwise like a dumbbell, various types of arrays having a weight corresponding to the content of strength training are used. These arrays train the trainee's muscular strength by the force acting when gripping the handle and raising or lowering it or swinging the handle in the axial direction. By continuing such training, the arm, shoulder, chest, etc. The outer muscles (large muscles) can be strengthened.

[0003]

However, although the conventional array can simply train the outer muscle to exert a strong force, the conventional array, particularly the shoulder and chest required for the sport of swinging the arms, is required. It was not suitable for training inner muscles, which are small muscles. Sports that swing the arms include baseball pitching, volleyball attack, handball throwing, tennis serve, golf swing, swimming strokes, etc. This kind of sport is a tool at the tip or hand of the hand. It can be said that the presence or absence of the swing speed determines the ability of the competition. Therefore, in order to increase the speed of the tip of the body, it is desired to effectively train inner muscles such as shoulders and chests. Also, when the pitcher repeatedly performs a violent pitching motion as in baseball, it is essential not only to prevent the above-mentioned inner muscle injury, but also to recover quickly after abusing it. However, a tool mainly intended to train the outer muscle like a conventional array is hardly useful for such prevention and recovery, and it has been desired to develop an array capable of conditioning the inner muscle in a good state.

[0004] Therefore, the invention of claim 1 of the present invention enhances the exercise ability of the sport of swinging the arm by effectively performing the training for accelerating the hand, which is the tip of the body, and at the same time, improves the shoulder and the shoulder. It is an object of the present invention to provide a stick array capable of favorably conditioning an inner muscle such as a breast. Another object of the present invention is to provide a stick array capable of more accurately knowing whether or not the swing of the arm is properly performed. Another object of the present invention is to provide a stick array that can be used in an appropriate gripping state according to the size of a user's hand.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, the front end has a center of gravity, and the rear end faces the palm side or is lightly abutted. An array body formed in a size that allows the upper and lower surfaces of the substantially central portion to be gripped by a finger in a state where the finger is held, and the array body is provided on the distal end side, and the array body is gripped with the palm facing the body side, and It is characterized by comprising a resonating part that swings down while twisting and emits a different sound from the wind noise when the palm faces outward to the body below. Further, the invention according to claim 2 of the present invention has the configuration of the invention according to claim 1,
The array body is elongated and curved in an arc shape, and the resonance portion is provided with an internally hollow bulge on the inner curved surface, and the bulge has an elongated small hole. According to a third aspect of the present invention, in the configuration of the first or second aspect, a plurality of finger stoppers to which a fingertip is hooked are arranged along the length of the array body. It is characterized by being formed.

[0006]

7 is a cross-sectional view taken along the line VII-VII of FIG. 4, and FIG. 8 is a cross-sectional view taken along the line VIII-VIII of FIG.

The stick array 1 is an array capable of judging whether or not a swing exercise for lowering an arm from above to below is appropriate.
The array main body 2 is provided with a resonance section 4, a plurality of finger holes 8, 9 and the like. The array main body 2 has an elongated spatula shape as shown in FIG. The array main body 2 is formed of a metal material, and is covered with a synthetic resin material having elasticity using a thick metal plate as an aggregate.
They may be formed integrally. As shown in FIGS. 2 and 3, the array main body 2 has a substantially central portion 2 having a circular tip portion 2a.
c is made narrower and gradually widened toward the rear end 2b. In addition, as shown in the side view of FIG. 4 and the cross-sectional views of FIGS. 5 to 8, the array body 2 gradually increases its thickness toward the rear end 2 b with the tip 2 a being the minimum thickness. I have. The rear end portion 2b is rounded so as to be along the palm, so that it is easy to hold the array main body 2 in contact with the palm.

Further, in the array main body 2, as shown in FIG. 5, a circular through hole 2f penetrating from the upper surface 2d side to the lower surface 2e side is formed at the distal end portion 2a, and a weight (weight) is provided around the circular through hole 2f. 3 are buried, and the resonance part 4 is provided in the through hole 2f. The weight 3 is an annular metal weight 3 substantially equal to the inner diameter of the through hole 2f, and is buried in advance in the inner peripheral portion of the through hole 2f. With the provision of the weight 3, the center of gravity of the array main body 2 is located at the distal end portion 2a side, and when performing training in which the array main body 2 is gripped and swung down, the tip end side of the arm can be accelerated. It is. The resonance section 4 includes a lower lid member 5 and an upper lid member 6, and has a configuration in which the two members 5, 6 are combined and fitted into the through hole 2f to be integrated. The lower lid member 5 has a disc-shaped bottom plate 5a.
And a cylindrical peripheral wall 5b, the bottom plate 5a of which is equal to the diameter of the recess provided in the lower opening of the through hole 2f,
The diameter of the peripheral wall 5b is smaller than the inner diameter of the through hole 2f. The upper lid member 6 is formed by integrally forming a circular bulged portion 6a having a raised upper surface side 6c and a cylindrical peripheral wall 6b, and the bulged portion 6a is provided in an upper opening of the through hole 2f. The diameter of the peripheral wall 6b is smaller than the inner diameter of the through hole 2f, and is larger than the outer diameter of the peripheral wall 5b of the lower lid member 5. Also,
An elongated small hole 6d is formed at the top of the upper surface side 6c to generate a resonance sound. The small hole 6d penetrates the resonance section 4 so that the length direction of the small hole 6d overlaps the extending direction of the array body 2. Attach to hole 2f.

At the time of this attachment, the through holes 2f
An adhesive is applied to the inner peripheral surface of each of the above, the recesses of the upper and lower openings, and the like. Then, the peripheral wall 6b of the upper lid member 6 is inserted from the upper opening, and the peripheral edge of the bulging portion 6a is fitted into the recess. Thereafter, the peripheral wall 5b of the lower lid member 5 is inserted through the lower opening,
Along the inner surface of the peripheral wall 6b of the upper lid member 6, the peripheral edge of the bottom plate 5a is fitted into the recess. Thereby, the upper lid member 6
And the lower lid member 5 are integrated in the through hole 2f,
b and 6b form the hollow portion 7 and the array body 2
The resonance portion 4 is formed by projecting the bulging portion 6a from the inner curved surface of the tip portion 2a of the rim. In this manner, at the distal end portion 2a of the array main body 2 which is entirely curved in an arc shape, the elongated small hole 6 is formed in the bulging portion 6a which is hollow inside and projects from the upper surface 2d side.
When d is provided, when the stick array 1 is swung down while being twisted from above to below as described later, a different resonance sound different from a normal wind noise can be generated. The first and second finger-stop holes 8 and 9 form an elliptical recess 2g substantially at the center 2c of the upper surface 2d of the array main body 2 and penetrate so as to be arranged in the longitudinal direction of the recess 2g. It has two holes. The finger stopper holes 8 and 9 are formed such that the inner peripheral edges of the openings on the upper surface 2d and the lower surface 2e are tapered so that the tips of the thumb and the middle finger can be easily locked or fitted. As a result, as shown in FIG. 9, the rear end 2b of the array main body 2 faces the palm 10a of the right hand 10 or lightly abuts thereon, and the thumb 10b is brought into contact with the upper surface 2d of the array main body 2, the index finger and the middle finger (not shown). ) And the ring finger 10c etc.
e. At this time, the tip of the middle finger is hooked or fitted into the first finger hole 8 from the lower surface 2e side, and the tip of the thumb 10b is applied to the upper surface 2d to grip the array body 2 as shown by the solid line 10b in the figure. However, as shown by a virtual line 10b in FIG.
The tip of the thumb 10b is connected to the first finger stop hole 8 on the upper surface 2d side.
Alternatively, the array main body 2 may be gripped or fitted to the main body. Thus, the substantially central portion 2 of the array body 2 is
When the finger c is gripped, the finger stopper hole 8 prevents the thumb or the middle finger from slipping, so that the stick array 1 does not drop even when the arm is lowered from above to below. Further, since two finger holes 8 and 9 are formed along the length direction of the array main body 2, it can be used in an appropriate gripping state according to the size of the user's hand.

[0010] The stick array 1 has an overall weight of 80 to almost equal the weight of a baseball.
It is manufactured within the range of g to 140 g. When the total length of the array body 2 is about 170 mm, the inner diameter of the hollow part 7 of the resonance part 4 is about 30 mm, the length W1 of the small hole 6d is about 10 mm, and the width W2 is within 5 mm (FIG. 2
reference). Stick array 1 configured as above
Improves the swing speed of the tip of the hand or the hand held equipment in sports where the arm swings, such as baseball pitcher, volleyball attack, handball throwing, tennis serve, golf swing, swimming stroke Suitable for exercise. It is also useful for preventing wear of the arms and shoulders or for properly conditioning the inner muscle after overuse.

Next, a case where the pitcher exercises using the stick array will be described. In baseball, the pitching action of the pitcher has a profound effect on the momentum of the ball and is closely related to the injury of the shoulder joint. This shoulder joint is divided into five joints,
Complex movements are made possible by linked play of muscles. In particular, the scapula-humeral joint between the humerus and the scapula has an unstable shape called a ball-and-socket. Therefore, balanced movement between the inner muscle and the outer muscle that supports this is important. The inner muscle has a centripetal effect in the deep part of the shoulder muscles and is responsible for stabilization, whereas the outer muscle is at the top and produces a large force due to the centrifugal action It is. The outer and inner muscles allow for various shoulder movements while maintaining an exquisite balance between efferent and centripetal. Therefore, there is no problem when the two are in balance, but there are many factors that break this balance in pitches that overuse the shoulder. In particular, the influence on the shoulder of the inner muscle is so great that the case where a problem occurs in the inner muscle is referred to as a state where the balance has been lost. Therefore, in order to prevent shoulder injury or to recover shoulder injury caused by overuse early, instead of strengthening inner muscles,
It is necessary to make adjustments (coordination) so that cooperation with the outer muscles can be performed smoothly.

[0012] For this coordination, it is important to keep the four muscles of the inner muscle, called the rotator cuff, consisting of the infraspinatus muscle, the supraspinalis muscle, the small circular muscle and the subscapularis muscle, in a healthy state. The subspinous muscle is the muscle on the front side (closer to the surface of the back) of the scapula, and the small circular muscle is located below this muscle. The subscapularis muscle is the muscle on the back side of the scapula, and the supraspinalis is located above the subscapularis and the subspinous muscle. The rotator rotates (rotor), and the cuff wraps around like a cuff, wraps the humeral head from four directions, and controls the inward and outward rotation while attracting the humeral head from the scapula side. . Thus, at the time of pitching of the pitcher, the scapulohumeral joint contributes to the stabilizing action of the arm, and at the same time, enables a pitching operation in which the movement of the arm is free to generate a large force. Therefore, if a method of efficiently accelerating the end portion of the body without exhausting the shoulder is adopted, the risk of breaking the shoulder is reduced even if the number of pitches is increased, and a natural movement for the body is achieved.

[0013] In this regard, in recent years, fork balls have attracted attention as a pitching method for accelerating the distal end portion, and pitchers throwing the fork balls have increased. However, this method of accelerating the distal end portion is an operation of pitching while taking damage to the shoulder for each ball, so that there is an aspect that the shoulder is easily hurt early although there are individual differences. Therefore, there is a demand for a method of moving the body and a pitching operation in which the shoulder is not hurt and the shoulder is hardly worn even by such an end portion acceleration method. It is also indispensable to keep the wear away with sufficient conditioning. As an exercise that meets these demands, it is said that it is effective to jog lightly and to shake the upper limb while twisting at this time. Jogging is a recovery method that is generally performed when an arm or shoulder is overused, but a better effect can be obtained by adding a motion of swinging the upper limb to this. When swinging this upper limb, according to the results of experiments conducted by the present inventors, swinging when lowering mercury in a thermometer is most natural,
It was confirmed that the inner muscle could be easily coordinated.

That is, when lowering the temperature of the thermometer, usually, the rear end of the thermometer is gripped with a finger in a state where the palm faces the body side, and is swung down while twisting from above, and the palm is directed outward with respect to the body below. I am trying to be. This is a movement that is performed daily without any special teaching, and can be said to be a natural movement that is natural for the body. Therefore, the present inventors have focused on the fact that this operation is useful for sports involving swings for accelerating a distal part of the body, for example, exercise of a pitcher or the like, and develop the aforementioned stick array 1 suitable for this. Reached. The stick array 1 emits a unique resonance sound when the same swing is performed by the spatula-shaped array body 2 and the resonance unit 4 when lowering the mercury of the thermometer. For example, when the stick array 1 is swung down while twisting from above, the array main body 2 is moved in the direction of arrow A in FIG.
Moves, the flow of air near the tip 2a becomes as shown by the arrow, and enters the hollow portion 7 through the elongated small hole 6d. At this time, since a flow of air occurs when a whistle is blown, a different resonance sound different from a mere normal wind noise is generated.

Next, a case where the pitcher exercises using the stick array will be described. FIG.
1 is an exercise in a standing posture of the pitcher,
FIG. 12 shows an exercise while jogging. First, as shown in FIG.
0 thumb 10b, middle finger, or the like. Then, the wrist joint is in a palm flexion state (the position of the wrist when the fox is represented in the shadow picture), the array body 2 extends from the tip of the right hand 10 so as to bend, and resonates with the instep 10d of the thumb 10b of the right hand 10. Part 4
Is aimed at. Then, to generate a resonance sound from the stick array 1, the right arm 11 is lifted upward as shown in FIGS. 11 (a) and 12 (a). Now the palm 10
The stick array 1 is gripped in a state where “a” faces the body 12. From this position, the stick array 1 is swung down while twisting the wrist (the wrist bends to the little finger side) as shown in FIGS. 11B and 12B. Then, as shown by arrows in FIGS. 11C and 12C, the pronation of the right arm 11 and the internal rotation of the upper limb are performed, and the palm 10a is directed outward with respect to the body 12 below. At this time, a flow of air is generated around the resonance section 4 as shown in FIG. 10 to generate a unique resonance sound. As a result, the trainee can judge that the proper swing has been performed.

In a series of swinging-down operations that generate such a resonance sound, the stick array 1 can be continuously held without putting force on the hand, so that the influence on the outer muscles such as the shoulders and chest exerting a strong force is exerted. Can be avoided, and intensive exercise of the inner muscles will be performed. That is, when the pitcher performs the rotation motion as described above, the upper and lower limbs of the right arm 11 are rotated inward and outward while the upper limb is close to the droop position. Then, the rotator cuff of the shoulder joint contracts by the recoil after the infraspinatus muscles and small circular muscles, which are the external rotator muscles, are stretched during internal rotation, and the opposite phenomenon occurs during external rotation, which is the lower scapula. Muscle extension and reaction contraction occur. As a result, exercises of the infraspinatus muscle and the infrascapularis muscle are performed alternately. In this exercise, when the arm is swung at a reciprocating rhythm of one reciprocation per second, 60 times per minute, 3600 times per hour, and 7200 times per second, the inner and outer rotation repetitive motions are repeated. This exercise has a significant conditioning effect on the rotator / cuff. As the screw is screwed, the rotation axis of the humeral head becomes more stable. When the humeral head gains stability over the glenoid fossa, the problems that result from the loss of stability, such as the "snagging" and "rubbing" of the shoulder, called impingement syndrome Such a phenomenon can be avoided.

Further, the exercise using the stick array 1 is excellent because the element of the rotator stretch shortening cycle (RSSC) which is close to the actual pitching operation during the exercise as described above is incorporated. Is a point. By repeating such a repetitive exercise,
It is considered that the work of taking in the original movement of the shoulder joint into the central system by a movement method similar to the pitching movement is performed. Further, according to the exercise method similar to the pitching operation, the tip 2a of the stick array 1 continues to accelerate from the point where the arm is swung to the point where the arm is swung. Therefore,
In the actual pitching motion after this exercise, the ball will leave without permission at the moment when the speed of the fingertip is accelerated to the maximum,
It becomes possible to release the ball in a constant space every time. Then, the released ball flies in a substantially constant direction. In addition to the baseball pitching action described above,
In sports activities that are likely to hurt the shoulder joint due to overuse, it can be said that the presence or absence of the swing speed of the tip of the hand or the equipment held in the hand determines the ability of the game. It is good to exercise.

[0018]

As described above, according to the first aspect of the present invention, the rear end portion faces the palm, the array body is gripped with the palm facing the body, and twisted from above. If you swing down, the different parts are different from the normal wind noise when the palm turns outward from the body below, so it is necessary to train inner muscles such as shoulders and chest In this case, training that accelerates the tip of the body, which is the tip of the body, can be effectively performed, and the exercise ability of the sport of swinging the arms can be increased, and the inner muscle after overuse can be favorably conditioned. In the invention according to claim 2 of the present invention, the array main body is elongated and curved in an arc shape, and the resonance portion is provided with an inner hollow bulging portion on an inner curved surface, and the bulging portion has an elongated bulging portion. Since the small holes are formed, it is possible to more accurately know whether the swing of the arm is properly performed. In the invention according to claim 3 of the present invention, a plurality of finger stoppers to which fingertips are hooked are formed along the length direction of the array main body, so that the finger stoppers can be appropriately adjusted according to the size of the user's hand. There is an effect that it can be used in a proper holding state.
