       TECHNICAL FIELD 
       [0002]    The present invention relates to a golf swing analysis apparatus which can easily analyze a trajectory of a golf swing, be used when an athlete, an enthusiast, a teacher or the like of golf practices or teaches the golf swing, and be used when a designer, a manufacturer or the like of a golf club designs or manufactures the golf club. 
       BACKGROUND ART 
       [0003]    Conventionally, in a case where an athlete or an enthusiast practices a golf swing, or in a case where a teacher teaches the golf swing, the way of swing has been learned by viewing a golf swing performed by a model using a tutorial, a video or the like of golf. 
         [0004]    Further, conventionally, in a case where a designer or a manufacturer of the golf club designs or manufactures the golf club, performance of a club has been checked through actual test hitting by an athlete and test hitting by a swing apparatus set with the club. 
         [0005]    However, it takes time to master a golf swing when learning the way of swing by viewing the model&#39;s golf swing through the tutorial, video or the like of golf. Thus, recently, a swing assist apparatus which enables an athlete and an enthusiast to master a golf swing by oneself while actually taking a swing, and a teacher to teach a golf swing (see Patent Literatures 1 and 2).

         [0078]    The base plate  52  is made of a thin metal plate or a synthetic resin plate, and mounting holes  52   a,    52   a  . . . are bored in four corner parts thereof so that the analysis apparatus  51  may be fixed at a predetermined part.

         [0083]    Further, when the cylinder shaft  63   b  is rotated, the arm part  57  can be rotated by an appropriate angle with respect to the body part  56 . 
         [0084]    In this manner, the rotating movement of the arm and the club using the body as the center axis of the swing can be realized. 
         [0085]    Here, the arm part  57  can be regarded as the first virtual axis. 
         [0086]    The arm part  57  includes an upper arm part  64  and a forearm part  65 , and the upper arm part  64  is rotatable about an axis thereof.

         [0095]    The golf swing analysis apparatus  51  is configured as described above. It is possible to form a usable state by fixing the leg part  55  of the pseudo human body  53  to the base plate  52 , setting the body part  56  at a predetermined angle with respect to the leg part  55 , setting the arm part  57  at a predetermined angle with respect to the body part  56 , and fixing the shaft part  68  of the pseudo club  54  to the arm part  57 . 
         [0096]    Here, if each length of the leg part, the body part and the arm part of the athlete or the enthusiast, as the subject, and the length of the club are measured, the pseudo human body  53  can be made to correspond to the subject by sliding cylinder shaft  53   b  to be fixed at the appropriate position and adjusting the length of the body part  56 . 
         [0097]    Further, when the telescopic rod  70  is extended or retracted to be set to an appropriate length, the angle between the arm part  57  and the pseudo club  54  can be adjusted. 
         [0098]    The golf swing analysis apparatus  51  can also realize each state at every time point in the trajectory of the golf swing by rotating the arm part  57  by a predetermined angle having the body part  56  as the axial center. 
         [0099]    Further, similarly to the golf swing analysis apparatus  1 , it is possible to analyze the trajectory of the golf swing by setting the state at the time of address, the state at the time of backswing, the state at the time of topswing, the state at the time of downswing, the state at the time of impact, the state at the time of follow-through, the state at the time of finish, and the like, and photographing each state at every time point.

Accordingly, it is possible to analyze the trajectory of the golf swing which further approximates to an actual human body. 
         [0101]    As described above, in the golf swing analysis apparatuses  1 ,  31  and  51  of the present invention, the left arm part and the right arm part are regarded as the first virtual axis which is integrated with one another. Accordingly, it is possible to perform analysis by simplifying each state during the golf swing. 
         [0102]    In other words, it is possible to simplify complexity that a length of right and left upper limbs serving as a reference changes between a rear side and a front side of a target line at a boundary of the address or the impact by regarding a line from a swing center to a grip end of the club as the first virtual axis. 
         [0103]    Further, the arm part as the first virtual axis is provided to be rotatable around the body part, and the golf club is provided to be rotatable in the hand part. Accordingly, it is possible to analyze the golf swing as a combination of the rotating movement of the first virtual axis and the cocking movement of the wrist. 
         [0104]    According to the golf swing analysis apparatus of the present invention, it is possible to simplify and easily understand that the movement of an upper body is formed with four basic movements of two rotations and two hinges combining the two rotations including the twisting movement of a trunk part and the rotation (rotating movement) of the first virtual axis, and the two hinge movements including a hinge movement corresponding to a so-called “movement of striking a head in Japanese fencing (kendo)” of a curved part formed between the trunk part and the first virtual axis in the swing center part, and a hinge movement corresponding to the cocking of the grip part. 
         [0105]    At the time of no-cocking, the hinge movements decrease by one so that it is simplified to two rotations and one hinge. In any case, it is possible to easily understand that the movement of the upper limb during the golf swing is the combination of the three to four basic movements. 
         [0106]    Further, according to the golf swing analysis apparatus of the present invention, it is assumed and understood that a mechanism is present in which the second virtual axis is rotated (performs rotation) (also referred to as a “rotating movement in a V-shape) in a state (so-called a shape of the letter “Ku” in Japanese hiragana (a V-shape)) where a constant angle is formed between the virtual axis in the grip part and a club shaft, which is considered as one of important movements that accelerates the movement of the club head. 
         [0107]    Further, it is assumed that such a mechanism is also present in other ball games in which a ball is flown far away, for example, baseball, tennis or the like. 
         [0108]    In addition, since each angle of the leg part, the body part, and the arm part can be appropriately set, it is possible to realize a forward inclined posture corresponding to the subject to be analyzed and to perform the analysis of the golf swing close to the reality.
