CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims priority under 35 U.S.C. §119 to Korean Patent Application Nos. 10-2014-0007114 filed on Jan. 21, 2014 and 10-2014-0135695 filed on Oct. 8, 2014, the disclosure of which is hereby incorporated by reference in its entirety. 
       BACKGROUND 
       [0002]    1. Field 
         [0003]    The present invention relates to a golf putter among various types of golf clubs for use in playing a golf and, more particularly, to a golf putter for enhancing the rolling straightness of a golf ball directed toward a hole and increasing the accuracy of putting by minimizing the errors and the mistakes in putting and by modifying the hitting surface shape of the putter head. In a typical way of putting until now, a golfer examines the green state and the distance before putting and determines the estimated trace of a golf ball. However, in real putting, the golfer stands looking at the golf ball and turns his face sideway unlike the observation posture that the golfer examined, and bows to the golf ball direction with his waist bent and his eyes turned sideway toward a hole. Then, he putts a golf ball finally depending only on his training experiences and his sense of views while still with the fears and uneasiness from the putting views changed from the observation views and the high possibility in errors raised from the differences between his observation and real putting in views and postures. Therefore, the present invention is directed to provide a golf putter by the configuration of which a golfer can practice swing and set up his posture for putting as the same way as he looked up the target hole at front and watched the estimated trace of the golf ball, and then still stands up beside the golf ball and putts the golf ball just like bowling while keep looking at the golf ball. 
         [0004]    2. Description of Related Art 
         [0005]    Generally, a swing putter  100  of a golf club includes a grip  101 , a shaft  102 , and a head  103  as shown in  FIG. 1 . While a golfer plays a golf and when uses a putter, he is positioned to stand up perpendicularly to the line that the putter moves and the hit ball proceeds which is a putting line, and bend down his waist, lower his or her both arms down, holds the grip  101  of the swing putter  100  and swings the putter left and right and putts the golf ball with the head  103 . 
         [0006]    As shown in  FIG. 2 , a golfer executes In-In swing with respect to the center line (L 1 ) of his spine. This is because the circular motion with respect to the spine central line (L 1 ) as axis is natural to follow by the law of nature. Depending on how much are the angle (θ 1 ) that the golfer bows, the angle of his arms (θ 2 ) to the spine central line (L 1 ) and the angle of his views (θ 3 ) that his eyes looks at the golf ball, the traces of golf ball movement, that is, each trace that the golf ball proceeds and travels brings different result. 
         [0007]    A golfer generally swings for putting at standard position with respect to the spine central line (L 1 ) while focusing and maintaining the angles (θ 1 , θ 2  and θ 3 ) as shown in  FIG. 2 . Then, the path for the golf ball  200  to proceed should be the way (T 1 ) as shown in  FIG. 3 . However, the moving direction of the golf ball  200  in real putting result may be turned to a second direction (T 2 ) as shown in  FIG. 3  due to the golfer&#39;s body structural feature and his In-In swing as normal. Or, in the case of correcting and adjusting his swing excessively, the moving direction of the golf ball  200  in real swing and putting may be a third direction (T 3 ) as shown in  FIG. 3  as the Out-Out swing or Neutral-Out swing. 
         [0008]    Generally, golfers practice the swing putting times out of number with putting a straight-shaped iron bar with a predetermined width on stroke area in order to prevent the golf ball  200  from proceeding toward the second (T 2 ) or the third direction (T 3 ), and to make the golf ball  200  proceed straightly along the first direction (T 1 ), and to increase the repeatability. Another stance of the golfer to swing the putter is shown in  FIGS. 4 and 5 , in which he stands and bows and bends his waist and his arms at right angle (90°) with respect to his spine central line (L 1 ) and he always swings and putts in the same angles and the same length while maintaining the angles of his waist and his arms ninety degrees (θ 4 =θ 5 =90°) and keeping the views angle of the golfer (θ 6 ) acute angle. Thus, it was intended to decrease the errors which may depend on mentally and physically different condition. In some case, a long putter (belly putter) may be used as shown in  FIGS. 6 and 7  in such way that the top portion of a grip  101  of a putter  100  is fixed to the belly or chest (B 1 ) of a golfer. 
         [0009]    As shown in  FIGS. 8 and 9 , a golfer examines in many directions in order to find out the exact track path reached from a golf ball  200  to a hole in advance before putting. In this step, the golfer may hunker down beside a golf ball, or bend his body, or even lay his face down on the green in order to precisely examine and estimate the track path of the golf ball to the target point (A 1 ). These positions are all proceeding with both two eyes facing at front toward the direction to be examined and seeing the direction of the target hole horizontally. 
         [0010]    Meanwhile, when the golfer determines the putting line, and he sets up his body line (L 2 ) for putting, and he finally checks the estimated track path of the golf ball to the target point (A 1 ) finally, it is now that he already bows and his body is bent down (θ 1 ≠θ 2 ≠θ 3 ≠90° in  FIG. 2 ) and he looks at the target point (A 1 ) with turning his face sideway which is shown in  FIGS. 10 and 11 . With his body bent forward with his eyes views downward at the golf ball and his spine central line angled between them, he has to turn his face sideway as much as 90° so that he results in seeing the target point (A 1 ) in completely different views from initially he examined and estimated the track path of the golf ball. In the instant moment like this, the golfer may be dismayed momentarily as result that he could not find out the target point (A 1 ) or the estimated track path exactly, or he may be confused to make him lose his confidence, which thus results in wrong putting swing. Therefore, the mistakes in swinging and putting bring the problems that the golf ball  200  may be proceeded in the direction (T 2  or T 3 ) as shown in  FIG. 3 . 
         [0011]    As shown in  FIG. 12 , when a golfer swings and putts a golf ball, he hits the golf ball without rolling the ball. Thus, the golf ball  200  slips with no rotation in the first region S 1  by the skid phenomenon, and then, rolls in the second region S 2 . Sometimes, the golf ball may be proceeded to a wrong direction even in the first region S 1 . Or, the direction and the distance of the golf ball  200  in the second region S 2  may be determined depending on the state of the green condition at the interface of the first and second regions S 1  and S 2 . Therefore, the distance to be rolled and the direction of the golf ball proceeding are not as good as examined and estimated previously, and sometimes unexpected results happen. This may be the problems in the swing by hitting, but there existed problems in the features of the hitting face of the head of the conventional swing putter  100 . 
         [0012]    As shown in  FIG. 18 , the putting surface  103   a  of the head  103  is made to have an angle (θ 12 ) mostly open upward. At putting, the golf ball  200  may bounce from the green grass  300  toward up due to the hitting angle (θ 11 ) of the golf ball. The rolling factor (r 1 ) of the ball according to the swing trace path may be reduced by the hitting angle (θ 11 ) and may be changed to reverse-rolling factor (r 2 ) so as to occur skid phenomenon and bring undesirable results. In order to overcome this problem and correct this fault, a golfer often executed swing by forcibly raising the head  103  upward, but the results just bring the swing errors such as putting to the direction of T 2  or T 3  in  FIG. 3   
         [0013]    Further, a normal swing must be executed along the direction (t 1 ) by the conventional swing putter  100  as shown in  FIG. 13 , but swing and strike out of sweet spot (t 2 , t 3 ) often occurs. Specifically, many problems and bad results in putting are brought in the putting direction or putting distance because of the errors or mistakes of, such as the angle (θ 7 ) from the strike by In-Out swing shown in  FIG. 14 , or the angle (θ 8 ) from the strike by Out-In swing shown in  FIG. 15 , and rather than the hitting direction of the face  103   a  of the head  103  to the golf ball  200  is maintained perpendicular to each other as normal as shown in  FIG. 13 , the hitting angle (θ 9 ) of the head  103  is closed swing as shown in  FIG. 16 , or the hitting angle (θ 10 ) of the head  103  is open swing as shown in  FIG. 17 , and so on. 
       SUMMARY 
       [0014]    Embodiments of the present invention provide a golf putter for use in putting a golf ball enabling a golfer to swing and putt a golf ball by the new posture with the new configuration of the putter while solving and improving the problems of the golf playing by conventional typical putters and changing the structure of the conventional typical putters. 
         [0015]    Embodiments of the present invention provide a golf putter enabling a golfer to swing and putt a golfer ball while standing at the same location where he or she examined the green state and the distance to a target hole and estimated the travel trace of the golf ball and imagined his or her putting line, and enabling the golfer to strike the golf ball while he or she can still look at the front and watch the golf ball moving similar to the bowling posture. 
         [0016]    Embodiments of the present invention provide a golf putter enabling a golfer to stand on the side of a golf ball, and swing and putt the golf ball while keep looking at the front and watching the putted golf ball, which is named as a look &amp; watching side swing putter (SSP), in short, referred to as SSP. The SSP of the present invention reduces putting errors raised from the putting postures and differences in views by use in conventional typical putters, and decreases the strokes to wrong directions. 
         [0017]    Embodiments of the present invention provide a look &amp; watching side swing putter (SSP) for improving the straight-lined movement of the golf ball during putting by decreasing skidding and increasing rolling of the putted golf ball with the putting surface of the putter head being reversely cambered. 
         [0018]    Embodiments of the present invention provide a look &amp; watching side swing putter (SSP) for putting a golf ball to roll naturally and smoothly by providing a shaft fixing point attached and fixed to the putter behind the putting surface of a putter head, and for increasing the surface friction of the putter against the golf ball toward its rotation direction at the moment of putting, thus to produce top spin of the golf ball by forming a groove aligned in parallel on the putting surface of the putter head. 
         [0019]    Embodiments of the present invention provide a look &amp; watching side swing putter (SSP), which is configured such that the lower edge on the putting surface of the putter head is made round and the above groove of the putting surface of the head is extended to this round-shaped edge in order to reduce putting errors which may occur by hit and impact of the golf ball on the lower corner portion of the head putting surface so that the putted golf ball moves toward wrong direction which is unpredicted and unwanted direction. 
         [0020]    Embodiments of the present invention provide a look &amp; watching side swing putter (SSP) for minimizing the errors results from the golf ball strike out of a sweet spot and preventing open or closed club face swing by forming the head such that its center of mass is distributed to both side ends. 
         [0021]    Embodiments of the present invention provide a look &amp; watching side swing putter (SSP) for considering the individual variation to the maximum in putting and reducing the errors due to these differences among individuals in order to improve the golf ball movement to straight-lined direction and allow consistent putting in results or posture by forming adjust weights on both side ends of the back portion of the head. 
         [0022]    Embodiments of the present invention provide a look &amp; watching side swing putter (SSP) in which a first indicator line and a second indicator line are respectively formed on the top surface of the putter head and the lower portion of the shaft, for two lines being connected to each other, and thus for a golfer to enable check the directional accuracy in his swinging and putting while seeing these two indicator lines moving by his own eyes in training or playing games in order to achieve good reproducibility in the direction. 
         [0023]    In accordance with an aspect of the present invention, the look &amp; watching side swing putter may include a second grip a golfer taking a grip on by one hand with his or her palm facing a first target direction; a second shaft located up and down the second grip and having a diameter as small as inserted into the fingers of a golfer without irritating; a first shaft extended up and down from the second shaft; a head provided at the bottom end of the first shaft; and a first grip provided at the top end of the first shaft. 
         [0024]    The look &amp; watching side swing putter of the present invention may be configured for a golfer to enable execute putting such that the golfer takes a grip on the second grip by his or her main hand with the palm of the main hand faced toward the direction of the first target and the golfer takes a grip on the first grip by the other hand for swinging back and forth without wavering just like the grip of the conventional typical putter or claw grip, and the golfer enable to stand beside a golf ball and swing the putter back and forth and hit the golf ball by the head of the putter and enable to keep watching the putted ball moving. 
         [0025]    The second shaft may be configured to have a diameter in the range of φ5 mm to φ7 mm to be inserted between the index finger and long finger of the golfer&#39;s hand or between the long finger and the ring finger when the golfer takes a grip on the second grip having a sphere shape. 
         [0026]    The head of the putter may be configured such that the putting surface of the head has reverse camber of a predetermined angle. 
         [0027]    The predetermined angle of the reverse camber may be made a reverse-incline angle in the range of 1° to 3° to the vertical line to produce top spin in order to improve the straight-lined direction movement of the golf ball being hit. 
         [0028]    The head of the putter may be configured such that the fixing point of the first shaft to the head is located on the back of the putting surface of the head in order to increase an upward vector quantity of the head by pendulum movement, and grooves aligned in parallel are formed on the reverse camber of the putting surface of the head in order to reduce the slip of the golf ball, and in order to produce top spin by increasing the surface friction to the rotation direction of the golf ball. 
         [0029]    The bottom edge portion of the putting surface of the head may be made to have round shape in order to prevent the putting error raised by the blow impact of the golf ball being hit to the head, and edge grooves are formed on the round-shaped edge portion of the putting surface of the head by extended from the grooves formed as above. 
         [0030]    The head may be made such that its center of mass is bidispersive along the both ends back of the putting surface in order to reduce the errors from the hitting results out of sweet spot and reduce the occurrence of the head distorted at swing. 
         [0031]    The head may be configured such that an adjust weight is formed on both back sides of the head in order to adjust the error factors in the right and the left direction raised from individual variation of putting and improve the straight-lined directional movement. 
         [0032]    The adjust weight may include weight coupling parts formed on both back sides of the head; and adjust weight members having different weights respectively and being able to be selectively coupled to the weight coupling parts. 
         [0033]    A first indicator line may be formed on the top surface of the head along its center line in order to help a golfer visually enable see his or her swinging back and forth accurately along the straight line, and a second indicator line may be formed on the lower portion of the first shaft to be extended from and connected with the first indicator line to secure good visual views. 
         [0034]    The head may be configured such that a plurality of blades with low stepped are formed on the bottom surface of the head along the putting direction in order to reduce the friction with green grass occurred when the head contacts and drags at putting and assist the straight-lined movement of the golf ball after being hit. 
         [0035]    The second grip may be made to include: a first stopper formed on the outside surface of one side of the second shaft; a plurality of second stoppers formed on the outside surface of the other side of the second shaft; a first hemisphere grip having a first hole, the first stopper being fitted into, and a plurality of nut insertion coupling holes; a second hemisphere grip having a plurality of second holes, the second stoppers being fitted into, and a plurality of second coupling holes, the second hemisphere grip faced with the first hemisphere grip; and bolts/screws for fixing the first hemisphere grip and the second hemisphere grip to the outer circumference surface of the second shaft to form a spherical shape and coupling the first and second hemisphere grips together. 
         [0036]    As described above, the look &amp; watching side swing putter (SSP) of the present invention most of all, allows a golfer to stand looking at a target hole in the front way and enable to putt a golf ball while maintaining the first posture as set for putting, and makes him or her keep watching the putted ball moving along the putting line. Therefore, the SSP of the present invention makes the swinging movement for putting a genuine pendulum movement to further reduce the errors and mistakes which often occurred in the past pendulum movement by the swinging and the putting in unnatural and unstable posture with the conventional typical putter to produce rotation of the golf ball. Further, the SSP of the present invention assures a golfer to execute better putting in more confidence and assurances because the structure of the SSP and the posture for putting reduce golfer&#39;s views differences between pre-examining and execution of putting, and resultingly, the differences between his estimated putting line that the golf ball would travel and the real putting result that the putted ball moves come to incredibly narrow, and the errors and the mistakes due to the differences and the disturbance in the past can be further decreased. 
         [0037]    Furthermore, a golfer can practice putting and train his swinging with sufficiently securing visual competitive so that he can check his swinging better in direction or not and the reproducibility in direction can be highly increased. The skidding of the putted golf ball is decreased and its rolling is increased. In addition, the side swing putter of the present invention provides the advantages of correcting swing errors raised from golfer&#39;s habitual and stubborn swing posture and inducing the strike of the putter to the golf ball at the moment of putting at perpendicular to each other (right angle: 90°). 
         [0038]    Particularly, the possibility of mistakenly strike on the lower edge in the past by use of conventional typical putter can be incredibly reduced or eliminated so that the momentary contact time at the hit moment of the golf ball with the head hitting surface of the SSP of the present invention can be extended, and even with minor slight swing mistake occurs, top spin can be produced and straight-lined directional movement can be improved. Furthermore, the resistance which the friction with the green grass may bring due to mistake at swing can be reduced and thus, the golfer can swing along the right direction and the hit golf ball can be proceeded along the straight line.

         [0078]    Referring to  FIGS. 19 to 25 , it will be explained in detail about the side swing putter (SSP) for golf ball putting while a golfer facing front and keep looking forward and putts a golf ball on the side of the ball according to an embodiment of the present invention, and hereinafter, the side swing putter (SSP) of the present invention may be noted as Look &amp; Watching SSP. The SSP of the present invention is configured to add a second shaft  40  and a second grip  50  to a first grip  10 , a first shaft  20 , and a head  30 , which are the components of a typical putter. 
         [0079]    The second grip  50  is placed in the middle of the second shaft  40 , and is configured for a golfer to be able to hold by his (or her) either one hand such that his palm of the hand is directed to face a first target direction. The first target direction means the direction which the hit ball is proceeding toward. 
         [0080]    The first shaft  20  has the diameter equal to or close to that of the conventional golf putter. The first shaft  20  is located between the head  30  and the first grip  10 , and specifically placed before and after the second shaft  40 . 
         [0081]    A second indicator line  21  is formed on the lower portion of the first shaft  20  as shown in  FIGS. 20 to 22 . The second indicator line  21  helps the golfer to see his swing accuracy visually when he swings a golf ball back and forth for putting on the side of a ball. 
         [0082]    The head  30  is located at one end of the first shaft  20 . On the putting surface of the head  30  is formed a reverse camber  31  having a predetermined angle (θ 14 ) as illustrated in  FIG. 23 . The predetermined angle (θ 14 ) of the reverse camber  31  is an inclined angle in the range of 1° to 3° with respect to a vertical line to produce top spin on the ball in order to enhance a straight-lined direction movement of the golf ball  200  being putted. 
         [0083]    The predetermined angle of the reverse camber  31  may be very small, which is formed such that the upper portion of the putting surface of the head  30  is thick and the lower portion of the putting surface of the head  30  is thin. 
         [0084]    As shown in  FIGS. 23 to 25 , a fixing point P 1  is formed on the head  30  behind the putting surface of the head  30 , and the first shaft  20  is fixedly positioned to the head  30  through the fixing point P 1 , which maintains a predetermined angle (θ 13 ) with the head  30 . As shown in  FIGS. 22 and 23 , a groove  32  shaped like multi steps in parallel are formed on the reverse camber  31  in order to produce top spin on the golf ball  200  by increasing its surface friction against the rotation direction of the golf ball  200  when a golfer swings and putts the golf ball  200  on the side of the ball. 
         [0085]    The edge on the lower portion of the putting surface of the head  30  is made round in order to reduce putting errors which may occur by hit and impact on the edge of the head as illustrated in  FIG. 23 . An edge groove  32   a  is formed on the round-shaped edge of the putting surface of the head  30  with extended from the groove  32 . 
         [0086]    As shown in  FIG. 24 , weight distribution units  33  are formed on the back of the head  30  opposite to the putting surface of the head  30  having the groove  32  formed as multi steps in order to distribute its center of mass to both side ends of the head  30  and reduce the putting errors out of sweet spot. Also, the weight distribution as above helps for head swing perpendicularly (90°). 
         [0087]    Further, an adjust weight  34  is formed on both side ends of the back portion of the head  30  in order to help correcting swing mistakes and to reduce the errors in swinging the putter to wrong direction incorrigibly and habitually. 
         [0088]    The adjust weight  34  comprises a weight coupling part  34   a  formed on the back portion of the head  30 , and adjust weight members  34  and  34   b  having different weight, for example, 12 g and 24 g, or screw of plastic dummy and selectively coupled with the weight coupling part  34   a.    
         [0089]    A first indicator line  35  is formed on the top surface of the head  30  as illustrated in  FIG. 24  in order to visually guide a golfer the accuracy of the swing direction in training of swinging or in putting a golf ball in golf play games on the green. On the bottom surface of the head  30  are formed a plurality of blades  36  aligned in parallel with low height illustrated in  FIG. 25  in order to reduce the friction of the head  30  with the top of the green grass in case that the head  30  of the putter comes to much contact with the grass on the green by swing mistakes, and in order to improve the direction of the ball travel as desired way of putting. 
         [0090]    The second shaft  40  is located between the portions of the first shaft  20  below the first grip  10  and above the head  30  respectively, and formed to have a smaller diameter than that of the first shaft  20 . The diameter of the second shaft  40  is in the range of φ5 mm to φ7 mm so that the second shaft  40  is inserted and held between forefinger and long finger or between long finger and fourth finger when the golfer holds and grips the second grip  50  having ball-shaped. 
         [0091]    The side swing putter (SSP) of the present invention is shaped for a golfer to enable swing and putt a golf ball in more ease and with more comfortable position while he stands and keeps looking at the front toward the direction to a hit golf ball should proceed. Also, the second grip  50  is configured to have a ball shape as described above, which is easy for a golfer to enable hold the shaft of the putter and grip the second grip  50  more firmly with the palm of his one hand facing toward the direction of a target to which a putted ball should proceed and settle into, and enable keep watching and checking how the putted ball proceeds after swinging and putting. 
         [0092]    The second grip  50  comprises a first stopper  51  formed on one side surface of the second shaft  40 , and a plurality of second stoppers  52  formed on opposite the other side of the second shaft  40 , a first hemisphere grip  53  having a first hole  53   a  which the first stopper  51  is fitted into, and a plurality of first nut insertion coupling holes  53   b , a second hemisphere grip  54  positioning in opposite to the first hemisphere grip  53  and having a plurality of holes  54   a  which the second stoppers  52  are inserted into respectively and a plurality of coupling holes  54   b , and fixing bolts  55  for coupling and fixing the two hemisphere grips  53  and  54  together when closely contact the first hemisphere grip  53  and the second hemisphere grip  54  together to the outer circumference surface of the second shaft  40  until to form a sphere shape and then, fix themselves to the second shaft  40  and be coupled to each other. 
         [0093]    That is, the first hole  53   a  of the first hemisphere grip  53  is inserted into the first stopper  51  formed on one outer surface of the second shaft  40 . The second holes  54   a  of the second hemisphere grip  54  are respectively inserted into the plurality of second stoppers  52  formed on the other opposite surface of the second shaft  40 . The first hemisphere grip  53  and the second hemisphere grip  54  are placed to face each other having the second shaft  40  between them. 
         [0094]    Then, a plurality of bolts  55  (or screws) are used to couple the two hemisphere grips  53  and  54  by inserting through the second coupling holes  54   b  of the second hemisphere grip  54  and the first nut insertion coupling holes  53   b  of the first hemisphere grip  53  having nuts inserted there inside. Thus, the ball-shaped second hemisphere grip  50  is fixed to the second shaft  40  and the coupling is completed. 
         [0095]    Now, it will be described with reference to  FIGS. 26 to 28  that the side swing putter (SSP) constructed as above according to an embodiment of the present invention allows a golfer to enable look at the target hole at front and while keeping the stance of looking at front, to enable putt the golf ball  200  to move in the same direction as he strikes the golf ball after he imagined the travel line of the golf ball previously (estimated trace of the golf ball). Also, the golfer can look at the front way and keep watching every trace of the golf ball moving toward the target hole at the same time of putting the golf ball  200  without turning his face sideway. 
         [0096]    As illustrated in  FIGS. 26 to 28 , a golfer grips the first grip  10  of the side swing putter (SSP) with one hand and grips the second grip  50  located below and having a ball shape with the other hand. Then, he looks at the putting line of the golf ball over the green at front, and swings the putter back and forth and putts the golf ball  200 . Then, after the golf ball  200  is struck, a golfer can keep watching the golf ball  200  moving toward and the travelling trace of the golf ball as well as the moment that the golf ball  200  is putted and hit. Particularly, the side swing putter (SSP) of the present invention employing use of the first and the second grips  10  and  50  can be preferred for the case of very close distance of or less than 1 m or by the golfers who like typical traditional way of putting, in such a way that a golfer takes stance watching at front and also may strike a golf ball at the direction perpendicular to the first target direction by traditional grip, or cross-handed grip, or claw grip, etc. Therefore, both right-handed and left-handed golfers can use the side swing putter (SSP) of the present invention with the characteristics as above of the right and left symmetric feature. 
         [0097]    When a golfer grips the first and the second grips  10  and  50 , the parting line of the second grip  50  is made to be formed behind the central line of the sphere-shaped grip so that its front hemisphere part is protruded more than the second shaft  40  and the grip by the golfer&#39;s hand fingers can be more tighten with more force. Then, the central line of the second grip  50  comes to become the line identical reaching from the shoulder joint of the golfer and-the central line of the second grip  50 —to the putting face of the sweet spot head  30  at the posture that the golfer sets his preparation for putting. Then, while the second grip  50  makes balance with the central line of the first shaft  20 , the golfer can induce a top spin on the golf ball  200  through the head  30 , during putting the golf ball  200 . 
         [0098]      FIG. 23  is an enlarged side view schematically showing the head of the side swing putter (SSP) according to one embodiment of the present invention. A golfer swings the side swing putter (SSP) back and forth in which the side swing putter (SSP) has a reverse camber  31  on the putting surface of the head  30  and a predetermined angle θ 14  as illustrated in  FIG. 23 . Then, when the golf ball  200  is putted, on the golf ball  200  is induced a top spin with an angle θ 15  to enhance the straight-lined directional movement as illustrated in arrows r 1  and r 2  of  FIG. 29 . At the same time, top spin can be produced by the existence of the groove  32  formed on the reverse camber  31  by increasing the surface frictional force toward the rotation direction of the golf ball  200  as illustrated in  FIG. 23 . 
         [0099]    As illustrated in  FIGS. 22 and 23 , the edge portion of the head  30  on the lower side of the putting surface is made to be round, and an edge groove  32   a  is formed on the round-shaped edge portion with extended from the groove  32 . Then, the putting error induced from the edge strike similarly to the topping of an iron shot can be reduced by using the side swing putter (SSP) according to an embodiment of the present invention. 
         [0100]    Here, the rounding on the edge portion of the lower side of the head  30  shall be preferably made radius of golf&#39;s swing back and forth, that is, the length from the shoulder of a golfer to the edge portion of the putting surface of the head  30 . Further, several more kinds of rounding shape may be made depending on the standard body models of golfers. 
         [0101]      FIGS. 24 and 25  are enlarged views of the head of the side swing putter (SSP) of the present invention. As illustrated in  FIG. 24 , weight distribution units  33  are formed on the head  30  to distribute its center of mass to both sides of the head  30 . In addition, an adjust weight  34  is provided to help adjust the weight of the head  30  which is different at both sides of the head  30  in order to reduce the errors in swinging the putter from incorrigible habits depending on individuals. Adjust weight members  34   b  being different in weight from each other can be coupled into weight coupling parts  34   a  positioned at both rear sides of the head  30 , the structure of which helps the golfer enable position the head  30  and swing perpendicular to the proceeding direction of the golf ball after putting. Thus, the putting errors occurred depending on the shoulder of the golfer being open or closed can be reduced and the errors of the putting results out of sweet spot can be minimized. That is, the errors of putting and swinging raised habitually and incorrigibly can be adjusted to the minute by the adjust weight elements as above. 
         [0102]    Each of the adjust weight members  34   b  is different in weight from each other, and it may have a weight of, for example, 12 g, 24 g, and so on, and may be made as a screw of several types metal materials, according to one embodiment of the present invention. Any one weight of the adjust weight member  34   b  can be selected by several swinging practices. The determined metal material screw for the adjust weight member  34   b  with a determined weight can be selectively fit into the weight coupling part  34   a  on either of the left or right side on the rear surface of the head  30 , so as to adjust the weight of the head  30 . In the event that it is not necessary to adjust the weight of the head  30 , a dummy screw being light in weight, its inside being empty, as the adjust weight member  34   b  may be fit into the weight coupling part  34   a.    
         [0103]    As illustrated  FIGS. 20 and 22 , a first indicator line  35  is formed on the front surface of the head  30  in the side swing putter (SSP) of the present invention as same as a second indicator line  21  is formed on the front portion of the first shaft  20  being connected to each other. These two straight lines on the top surface of the head  30  and the surface of the first shaft  20  assist a golfer to execute the putting more effectively during training or putting on the grass, so that he can swing the side swing putter (SSP) of the present invention back and forth while he keeps checking by his eyes weather his swinging is done along the right straight direction or not. 
         [0104]    When a golfer strikes the golf ball  200  by swinging the side swing putter (SSP) back and forth, the blades  36  formed on the bottom of the head  30  helps to reduce the drag or the friction of the bottom surface of the head  30  with the top surface of the grass on the green and assists for the golfer to swing and putt to improve the straight-line movement in the event that the head  30  of the putter is dragged or make friction with the grass. 
         [0105]    As described above, the look &amp; watching side swing putter (SSP) according to the present invention was described with embodiments in detail referring to accompanied drawings. The embodiments are illustrative, but do not limit the concepts and spirits of the present invention. 
         [0106]    In view of the foregoing, an embodiment of the side swing putter according to the present invention provides a putter which assists a golfer to enable watch and check his (or her) swinging and putting more easily and more correctly during practices or golf matches and results in him enable to execute better putting. The possibility of the hitted golf ball being skidded is further decreased and being rolled more correctly along the straight-lined direction toward the target is more increased. Also, it is induced for the golfer to correct his swinging posture which was fallen in habitual mistakes and putting errors so that the possibility that the head strikes the golf ball more accurately is further increased. Further, the side swing putter of the present invention brings up the effects of the golf ball forward directed in straight line enhanced with top spin even occurs in slight swing errors while eliminating the possibility of mistaken shot from wrong strikes on the bottom edges and extending the momentary contact time of the golf ball with the head putting surface. Also, the side swing putter of the present invention helps the straight line movement of the golf ball being putted while reducing the friction with green grass often occurred by putting mistakes and inducing the golfer to enable swing along more accurate direction.
