Priority for this application is claimed from U.S. Provisional Application No. 61/667,788 entitled “Golf Training Apparatus” filed on Jul. 3, 2012 
    
    
     BACKGROUND 
     The present invention is directed to a golf swing training apparatus for teaching a preferred path upon which to swing a golf club and, simultaneously, strengthening the muscles used to move the club along such swing path. 
     Golfing requires a multitude of skills and strength in addition to applying knowledge of proper form for correctly swinging the golf club. Many types of devices have been developed for improving the swing of a golfer. 
     Each golfer has an individualized size and style that must be taken into consideration for effective learning or teaching the sport. The height, body shape and swing of each golfer are ail unique characteristics that must be addressed when using a training device. 
     Conventional training devices do not provide guidance with respect to a proper swing path while increasing the strength of the muscles used in performing the required swing. Furthermore, there is a lack of adjustability in conventional devices and, therefore, such devices fail to suit the needs of many potential users having incompatible physical characteristics. This lack of adjustability diminishes the versatility of these prior art training devices. Consequently, additional devices are needed to train users having different size requirements. 
     The swing training apparatus of the present invention provides means for a user to learn how to correctly swing a golf club while strengthening the muscles required to perform such action. Additionally, the apparatus is highly versatile, being adjustable to fit golfers of varying physical attributes and abilities. 
     SUMMARY 
     The golf swing training apparatus and method of using the present invention includes a swinging device having an inner guide loop that pivots within an outer base loop. The inner guide loop is moved by a user swinging a simulated golf club. A tensioning device is provided to create resistance to movement of the inner guide loop. The resistance can be adjusted to different tensions, each tension requiring a different magnitude of force to move the inner guide loop. The greater the resistance, the more participation is required by targeted muscles of the user. For users having lower skill levels, the selected resistance can be relatively low. As a trainee progresses, the resistance can be increased incrementally to develop the musculature used for swinging a club, as well as the muscle memory of swinging the club and proper form of the user. 
     In addition, the apparatus is adjustable to fit the particular body height and shape of a golfer and adjustable to the proper swing plane angle for that golfer. Consequently, one can train correctly for his or her particular body type and for his or her particular swing.

     DETAILED DESCRIPTION 
     As shown in  FIGS. 1 ,  2 , and  5  of the drawings, a preferred embodiment of the golf training apparatus ( 1 ) of the present invention includes a swinging device ( 30 ), a stand ( 10 ) for supporting the swinging device ( 30 ) and a means for adjusting the swing plane of the swinging device. The means for adjusting the swing plane is an angle adjuster ( 70 ). 
     The swinging device ( 30 ) includes an inner guide loop ( 31 ), an outer base loop ( 32 ), means for moveably supporting the inner guide loop on the outer base loop, means for maintaining variable resistance on the inner guide loop and means for moving the inner guide loop on the outer base loop. 
     The inner guide loop ( 31 ) is a swing track having an inside surface ( 81 ), an outside surface ( 82 ), a guide rail ( 83 ) and a tool guide ( 84 ). The outer base loop ( 32 ) provides support for the inner guide loop ( 31 ). 
     Means for moveably supporting the inner guide loop on the outer base loop is a loop holder ( 33 ). The loop holder ( 33 ) comprises a plurality of roller supports ( 42 ) disposed around the perimeter of the outer base loop ( 32 ). Each of the roller supports ( 42 ) comprises first ( 45 ) and second ( 46 ) rollers and a supporting bracket ( 44 ) as shown in  FIG. 3 . 
     The means for maintaining variable resistance on the inner guide loop is a tensioning device ( 35 ) and a tension adjuster ( 55 ). 
     Referring to  FIGS. 1 and 7 , the means for moving the inner guide loop on the outer base loop is a tool ( 88 ), preferably a simulated club ( 34 ) having a shaft ( 37 ) with a grip ( 36 ) on a proximal end and universal joint ( 38 ) on the opposite, distal end attached to the inner guide loop ( 31 ). The shaft ( 37 ) comprises inner ( 39 ) and outer ( 40 ) telescoping rods that slide relative to each other, thereby enabling the length of the shaft ( 37 ) to vary. 
     The inner guide loop ( 31 ) is substantially circular in its overall shape and is sized to fit within the outer base loop ( 32 ). Consequently, the inner guide loop ( 31 ) has a diameter that is less than a general diameter or width of the outer base loop ( 32 ). In a preferred embodiment, the outer base loop ( 32 ) is substantially octagonally shaped. However, the shape of the outer base loop could vary, if desired. For instance, the outer base loop could be substantially circular, square, or any other shape that would adequately support the inner guide loop. 
     The tension adjuster ( 55 ) of the tensioning device ( 35 ) shown in  FIGS. 1-3  is an elongated element having a first end which comprises a handle ( 56 ), a second end which comprises an engaging portion ( 57 ), and a midsection disposed between the first and second ends. The midsection has a threaded portion ( 58 ) that is threadedly engaged with and supported on the angle bracket ( 54 ). Preferably, the tension shoe ( 53 ) is a wheel and is adapted to frictionally engage the first roller ( 45 ) of the roller support ( 42 ). The tension shoe ( 53 ) can be adjusted to provide various selected magnitudes of resistance in order to selectively modulate movement between the inner guide ( 31 ) and outer base ( 32 ) loops when a user is swinging the simulated club ( 34 ) on the apparatus ( 1 ). 
     Each of the supporting brackets ( 44 ) on the roller supports ( 42 ) has a stabilizing arm ( 47 ). The stabilizing and ( 47 ) of each support bracket ( 44 ) is generally L-shaped and fits over and partially surrounds the guide rail ( 83 ). The guide rail ( 83 ) slides within the stabilizing arms ( 47 ) as the inner guide loop ( 31 ) moves relative to the outer base loop ( 32 ). 
     The tool guide ( 84 ) on the inner guide loop ( 31 ) is preferably made of ultra-high molecular weight polyethylene which allows an actual golf club to be drawn along the front edge of the inner guide loop during a practice swing without damaging the golf club. It is noted that other suitable materials could be used, if desired. 
     The shaft ( 37 ) of the simulated club ( 34 ) is preferably made from steel. However, other suitable materials, such as graphite or fiberglass, could be used instead. 
     The stand ( 10 ) supports the swinging device ( 30 ) of the golf training apparatus ( 1 ). The stand ( 10 ) includes a base ( 11 ), a pair of upright supports ( 12 ), and means for adjusting the height of the swinging device. The base ( 11 ) includes a frame ( 14 ) adapted for resting on a supporting surface and a platform ( 15 ) mounted atop the frame ( 14 ). On the stand ( 10 ), the platform ( 15 ) provides an area on which a user can stand during training. The overall length of each upright support ( 12 ) can be adjusted in order to vary the height of the swinging device ( 30 ). By changing the height of the upright supports ( 12 ), the golf swinging device ( 1 ) can be adjusted to accommodate differently sized users. 
     The means for adjusting the height of the swinging device, as shown in  FIG. 9 , is a height adjustment device ( 13 ) that is infinitely adjustable. Each of the upright supports ( 12 ) of the stand ( 10 ) comprises a pair of adjustable telescoping members ( 16 ). The height adjustment device ( 13 ) includes a pair of locks ( 17 ). A lock ( 17 ) is disposed on each of the upright supports ( 12 ) and releasably holds the telescoping members ( 16 ) of the respective upright support ( 12 ) in a selected adjustable position. The lock ( 17 ) includes a set screw ( 18 ) and a threaded sleeve ( 19 ). The set screw ( 18 ) is disposed within the threaded sleeve ( 19 ) and is threadedly engaged therewith. The set screw ( 18 ) can be rotated in one direction in order to engage with the cooperating telescoping member ( 16 ). When engaged, the set screw ( 18 ) locks the adjustable telescoping members ( 16 ) of the respective upright support ( 12 ) in the selected position for a desired height of the swinging device ( 30 ). Conversely, the set screw ( 18 ) can be rotated in an opposite direction to release the lock ( 17 ), allowing the respective telescoping members to slide relative to each other. 
     Means for adjusting the swing plane of the swinging device ( 30 ) is an angle adjuster ( 70 ), as shown in  FIGS. 5 and 6 . The angle adjuster ( 70 ) adjustably supports the swinging device ( 30 ) at various selected angles on the stand ( 10 ) and comprises a pair of angular pivot joints ( 72 ) and an angle gauge ( 71 ). The angle gauge ( 71 ) includes a series of lock apertures ( 74 ) and a lock pin ( 73 ). The angle gauge ( 71 ) indicates the particular angle at which the swinging device ( 30 ) is set. The angular pivot joints ( 72 ) connect the outer base loop ( 32 ) to respective upright supports ( 12 ) of the stand ( 10 ). The angular pivot joints ( 72 ) pivotally support the swinging device ( 30 ) on the stand ( 30 ). The angular adjuster ( 70 ) can be locked into the selected position by engaging the lock pin ( 73 ) with the particular lock aperture ( 74 ) associated with the selected angle. By setting the swinging device ( 30 ) at various selected angles, each of which represents a unique swing plane, the golf training apparatus ( 1 ) can be adapted for use by different individuals. 
     Referring to  FIG. 7 , the telescoping rods ( 39 ,  40 ) comprised by the shaft ( 37 ) of the simulated club ( 34 ) slide relative to each other to change the effective length of the simulated club&#39;s shaft ( 37 ). During use, the golfer holds the grip ( 36 ) of the club ( 34 ) and begins the swing by bringing the club ( 34 ) back into a back swing and then starts the forward swing by bringing the club ( 34 ) down and forward. Throughout the swing, the effective length of the club&#39;s shaft ( 37 ) typically changes since the inner ( 39 ) and cuter ( 40 ) telescoping rods are free to slide relative to each other. 
     The simulated club ( 34 ) is removably attached to the inside surface ( 81 ) of the inner guide loop ( 31 ) by the universal joint ( 38 ) which includes a ball ( 41 ) and socket ( 48 ). The universal joint ( 38 ) allows rotational movement of the simulated club ( 34 ) with respect to the inner guide loop ( 31 ) so that the user can freely swing the simulated club ( 34 ) backwards and forwards during use. The ball ( 41 ) pivots within the socket ( 48 ) of the universal joint ( 38 ). The ball ( 41 ) can be selectively snapped out of the socket ( 48 ) when it is desirable to remove the simulated golf club ( 34 ) from the inner guide loop ( 31 ). Conversely, the simulated club ( 34 ) can be reattached to the inner guide loop ( 31 ) by snapping the ball ( 41 ) back into the socket ( 48 ). 
     The tool guide ( 84 ) shown in  FIG. 4  is disposed along a front edge of the inner guide loop ( 31 ) and functions to protect an actual golf club from damage when the club is swung around the inner guide loop ( 31 ). In such an alternate use, the simulated club ( 34 ) is preferably removed from the inner guide loop ( 31 ) as previously mentioned and an actual golf club can be drawn along the front edge of the inner guide loop ( 31 ). During such use, the tool guide ( 84 ) on the inner guide loop ( 31 ) can directly engage the shaft of the golf club. The shaft can smoothly slide along the tool guide ( 84 ) without marring the club&#39;s shaft. 
     The outer base loop ( 32 ) of the swinging device ( 30 ) supports the inner guide loop ( 31 ). The plurality of roller supports ( 42 ) holds the inner guide loop ( 31 ) onto the outer base loop ( 32 ) and allows the inner guide loop ( 31 ) to pivot or roll on the first ( 45 ) and second ( 46 ) rollers shown in  FIGS. 1-4  and  8 . The first ( 45 ) and second ( 46 ) rollers also stabilize the inner guide loop ( 31 ). The stabilizing arm ( 47 ) of the supporting bracket ( 44 ) partially surrounds the guide rail ( 83 ) of the inner guide loop ( 31 ) and assists in supporting the inner guide loop ( 31 ) in position on the outer base loop ( 32 ). 
     The tensioning device ( 35 ) provides a variable resistance between the inner guide loop ( 31 ) and the outer base loop ( 32 ). The resistance to the movement of the inner guide loop ( 31 ) on the outer base loop ( 32 ) can be selectively adjusted to varying degrees ranging from negligible resistance to strong resistance. The tension adjuster ( 55 ) of the tensioning device ( 35 ) functions to increase or decrease the resistance that is applied through the tension shoe ( 53 ) to the first roller ( 45 ) of the adjacent roller support ( 42 ). The angle bracket ( 54 ) threadedly engages and supports the elongated tension adjuster ( 55 ). The tension shoe ( 53 ) is disposed on the pivot arm ( 52 ) and is adapted to engage the first roller ( 45 ) of the adjacent roller support ( 42 ). By rotating the handle ( 56 ), the tension adjuster ( 55 ) can be moved toward and away from said roller ( 45 ) to vary the pressure exerted by the tension shoe ( 53 ) on the first roller ( 45 ) of the adjacent roller support ( 42 ). The pressure applied to the first roller ( 45 ) by the tension shoe ( 53 ) creates resistance to movement of the inner guide loop ( 31 ). The resistance applied to the inner guide loop ( 31 ) by the tensioning device ( 35 ) can be increased or decreased to modulate the ease with which the inner guide loop ( 31 ) and an attached simulated club ( 34 ) can be moved. 
     The greater the resistance that is applied to the first roller ( 45 ) via the tensioning device ( 35 ), the more force is required by the user to swing the simulated club ( 34 ) and move the inner guide loop ( 31 ) within the outer base loop ( 32 ). This resistance during the swing enhances the user&#39;s muscle strength and memory. Conversely, the less the resistance applied to the first roller ( 45 ), the less force is required by a user to swing the stimulated club ( 34 ) and move the inner guide loop ( 31 ). 
     The inner guide loop ( 31 ) is disposed within the cuter base loop ( 32 ) and held in place on the outer base loop ( 32 ) by the roller supports ( 42 ). The roller supports ( 42 ) are spaced around a perimeter of the outer base loop ( 32 ) as shown in  FIG. 1 . On the inner guide loop ( 31 ), the guide rail ( 83 ) is disposed on the outside surface ( 82 ) of the inner guide loop ( 31 ) adjacent to a rear edge thereof, while the tool guide ( 84 ) is disposed along a front edge of the inner guide loop ( 31 ). On each roller support ( 42 ), the first ( 45 ) and second ( 46 ) rollers are disposed generally perpendicular to each other, such that the first roller ( 45 ) engages one side of the guide rail ( 83 ) and the second roller ( 46 ) engages another side of the guide rail ( 83 ) that is generally perpendicular to the guide rail&#39;s one side. Each of the supporting brackets ( 44 ) is attached to the cuter base loop ( 32 ) and supports a respective first ( 45 ) and second ( 46 ) roller thereon. Each supporting bracket ( 44 ) includes a stabilizing arm ( 47 ) that fits over a portion of the guide rail ( 83 ). Each of the stabilizing arms ( 47 ) allows the guide rail ( 83 ) to slide through as the inner guide loop ( 31 ) rotates with respect to the cuter base loop ( 32 ). 
     Each of the upright supports ( 12 ) of the stand ( 10 ) is mounted at a lower end onto the base ( 11 ). The upper ends of the upright supports ( 12 ) are mounted to opposite sides of the swinging device ( 30 ). The platform ( 15 ) is disposed on the frame ( 14 ) of the base ( 11 ). 
     The means for adjusting the swing plane is disposed on the upright supports ( 12 ) of the stand ( 10 ). One of the pivot joints ( 72 ) of the angle adjuster ( 70 ) attaches the upper end of a respective upright support ( 12 ) to one side of the outer base loop ( 32 ). The other of the pivot joints ( 72 ) attaches the upper end of the other upright support ( 12 ) to an opposite side of the outer base loop ( 32 ). The angle gauge ( 71 ) is positioned on one of the upright supports ( 12 ). The angle gauge ( 71 ) includes a plurality of slot-shaped lock apertures ( 74 ) that are adapted to receive the lock pin ( 73 ) therein. 
     To adjust the swing plane, the angle for the desired swing plane is selected on the angle gauge ( 71 ). The swinging device ( 30 ) is then positioned to coincide with the selected angle and the lock pin ( 73 ) is inserted into the associated lock aperture ( 74 ) to thereby secure the selected angle for the swing plane of the swinging device ( 30 ). 
     On the simulated club ( 34 ), the universal joint ( 38 ) pivotally joins the shaft ( 37 ) of the simulated club ( 34 ) to the inside surface ( 81 ) of the inner guide loop ( 31 ). The universal joint ( 38 ) is comprised of a ball ( 41 ) and socket ( 48 ). The ball ( 41 ) is pivotally held within the cooperating socket ( 48 ) by a snap fit. When desired, the ball ( 41 ) of the universal joint ( 38 ) can be removed from the socket ( 48 ) to detach the simulated club ( 34 ) from the inner guide loop ( 31 ). 
     The inner guide loop ( 31 ) is sized to fit within the outer base loop ( 32 ) as shown in  FIG. 1 . The inner guide loop ( 31 ) is held in position by the plurality of roller supports ( 42 ). The roller supports ( 42 ) are supported on the outer base loop ( 32 ). Consequently, the inner guide loop ( 31 ) is held within the cuter base loop ( 32 ). The tensioning device ( 35 ) is attached to the outer base loop ( 32 ) adjacent to one of the roller supports ( 42 ) as shown in  FIG. 3 . The tensioning device ( 35 ) applies pressure to the first roller ( 45 ) that acts as a brake to hinder movement of the inner guide loop ( 31 ). The resistance applied to the first roller ( 45 ) through the tensioning device ( 35 ) is imparted to a golfer as he or she swings the simulated club ( 34 ). 
     Four roller supports ( 42 ) are spaced generally equidistantly apart around a perimeter of the outer base loop ( 32 ) and a fifth roller support ( 42 ) is disposed to engage the lowermost point of the inner guide loop ( 31 ) supported thereby. The rollers ( 45 , 46 ) of each roller support ( 42 ) are disposed generally perpendicular to one another with the first roller ( 45 ) having an axis of rotation that is generally at a right angle to the axis of rotation of the second roller ( 46 ). Consequently, each of the first ( 45 ) and second ( 46 ) rollers engage adjacent sides of the guide rail ( 83 ). 
     At the beginning of the swing, the shaft ( 37 ) of the simulated club ( 34 ) is extending generally downward with the universal joint ( 38 ) being at an approximate lowermost point on the inner guide loop ( 31 ). As the simulated club ( 34 ) is drawn back, the distal end of the simulated club ( 34 ) moves in an upward circular motion. Since the distal end of the simulated club ( 34 ) is attached by the universal joint ( 38 ) to the inside surface ( 81 ) of the inner guide loop ( 31 ), the inner guide loop ( 31 ) moves on the roller supports ( 42 ) in a circular motion along with the simulated club&#39;s movement. The inner guide loop ( 31 ) moves in direct response to the movement of the distal end of the simulated club ( 34 ). 
     The simulated club ( 34 ) can rotate 360 degrees and the user can swing the club ( 34 ) in both backward and forward motions. The simulated club ( 34 ), when actuated by a user, typically precipitates the movement of the inner guide loop ( 31 ) which also can rotate a full 360 degrees on the outer base loop ( 32 ). 
     To use the golf training apparatus ( 1 ) of the present invention the apparatus is adjusted to the individual user by adjusting the height of the swing device with the height adjustment device ( 13 ), adjusting the swing plane of the apparatus with the angle adjuster ( 70 ) and setting the desired resistance with the tensioning device ( 35 ). 
     The user stands on the platform and grasps the simulated club ( 34 ) with a stance similar to that conventionally recognized for addressing the golf ball with a particular club. With hands on the grip ( 36 ) of the simulated club ( 34 ), the user takes a backswing whereby he or she brings the club back. Once the simulated club ( 34 ) is positioned at the top of the back swing, the user swings the simulated club ( 34 ) down, forward and through the golf swing. In order to build muscle tone and develop muscle memory for the correct swing, this swinging action can be repeated. The resistance on the inner guide loop can be changed as desired. In a preferred use, the resistance is increased incrementally as the resultant strength of the user increases. 
     To increase the resistance on the inner guide loop ( 31 ), the tension adjuster ( 55 ) of the tensioning device ( 35 ) is actuated. By turning the handle ( 56 ) on the first end thereof, the tension adjuster ( 55 ) rotates and the threaded portion ( 58 ) moves through the angle bracket ( 54 ) threadedly supporting the midsection of the tension adjuster ( 55 ). As a result, the engaging portion ( 57 ) of the tension adjuster moves forward thereby pushing the pivot arm ( 52 ) of the tensioning device ( 35 ) toward the first roller ( 45 ) increasing pressure of the tension shoe ( 53 ) against the first roller ( 45 ). The greater the pressure exerted against the first roller ( 45 ) by the tension shoe ( 53 ), the greater the resistance provided by the tensioning device ( 35 ) becomes, and the greater the force required to move the inner guide loop ( 31 ) becomes. Conversely, the less pressure that is exerted against the first roller ( 45 ) by the tension shoe ( 53 ), the less is the resistance provided by the tensioning device ( 35 ) on the inner guide loop ( 31 ) and the less is the force required to move the inner guide loop ( 31 ). 
     To decrease the resistance on rotation of the inner guide loop ( 31 ), the tension adjuster ( 55 ) is turned in an opposite direction. When the handle ( 56 ) is turned in the opposite direction, the tension adjuster ( 55 ) moves within the angle bracket ( 54 ) away from the pivot arm ( 52 ). As the tension adjuster ( 55 ) moves away from the pivot arm ( 52 ), the engaging portion ( 57 ) of the second end of the tension adjuster ( 55 ) decreases pressure on the pivot arm ( 52 ) so that the tension shoe ( 53 ) releases pressure and resistance on the first roller ( 45 ). Therefore, in order to release the pressure exerted on the first roller ( 45 ) and to reduce the resistance of the tensioning device ( 35 ), the tension shoe ( 53 ) is moved in a direction away from the first roller ( 45 ). 
     As the user moves through his or her swing with the simulated club ( 34 ), the shaft ( 37 ) of the simulated club ( 34 ) automatically changes length. The change in length of the shaft ( 37 ) is due to the telescoping rods ( 39 , 40 ) comprising the shaft ( 37 ). The rods ( 39 , 40 ) are able to slide relative to each other as the club ( 34 ) swings around the arc determined by the inner guide loop ( 31 ). 
     The golf training apparatus of the present invention promotes correct golf swing characteristics while discouraging incorrect ones. For instance, the apparatus encourages a user to perform a correct take-away, turn and downswing while keeping the club on the proper plane throughout the swing, and inhibits lagging the club upon take-away, bringing the club inside on the upswing and casting the club during the downswing. Consequently, the user is able to feel the proper form for swinging the club, as well as developing the strength for swinging the club. 
     The golf training apparatus of the present invention provides variable resistance training for a user to improve his or her golf swing by increasing muscle tone specific to the user&#39;s swing. The resistance training also develops the particular muscle memory for each individual&#39;s golf swing. The apparatus enables the user to practice his or her golf swing within the correct swing plane which reinforces the correct form. This is advantageous in developing the muscle memory for that correct swing form. The golf training apparatus can be adjusted for each individual user by the means for adjusting the height of the swinging device and the means for adjusting the swing plane of the swinging device. 
     Furthermore, the tensioning device is adjustable so that the resistance can be increased or decreased in accordance with the user&#39;s training needs. The resistance offered by the golf training apparatus of the present invention provides a myriad of advantages for training, including that of encouraging the user to turn his or her hips to start the downswing, activating the abdominal muscles of the user while keeping the lower body stable throughout the swing and assisting the user to maintain the proper angle between his or her arms and the club shaft during the swing. 
     In an alternate use, the simulated club ( 34 ) can be removed from the inner guide loop ( 31 ) of the apparatus ( 1 ) by snapping the ball ( 41 ) out of the socket ( 48 ) of the universal joint ( 38 ) on the club&#39;s shaft ( 37 ). With the simulated club ( 34 ) detached from the inner guide loop ( 31 ), the user can practice with his or her own golf club by standing on the platform ( 15 ) of the apparatus and resting the shaft of his or her own golf club against the tool guide ( 84 ) on the inner guide loop ( 31 ). The user then swings, sliding the club&#39;s shaft around the inner guide loop ( 31 ) while keeping it the shaft against the tool guide ( 84 ) throughout the entire swing. It is desirable that the swing mimic the form of the swing motion used during resistance training with the simulated club ( 34 ) attached to the apparatus ( 1 ). 
     It is noted that the golf training apparatus of the present invention may be modified to train and strengthen swings used in other sports, such as baseball, Softball, tennis, and the like. In such cases, the simulated club would be replaced with a simulated bat, racket, etc. and the swinging device and angle adjuster would be adapted to simulate the swings utilized in the particular sport for which improvement is desired. 
     Although the present invention has been described in considerable detail with reference to a certain illustrative embodiment, other embodiments are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the preferred version contained herein.
