DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to FIG. 1, an isometric view of a preferred embodiment of the putting training device 2 with the putter 4 resting on the guide member 6 is shown. More specifically, the putting training device 2 comprises a base 8 that has a first end 10 and a second end 12. A first shoulder 14 is included, and wherein the first shoulder 14 contains a horizontal leg 16 that extends to a vertical leg 18, and wherein the leg 16 is attached to the first end 10 via conventional means such as nuts and bolts, or gluing. The second shoulder 20 has a horizontal leg 22 that extends to a vertical leg 24, and wherein the second shoulder 20 is also attached to the base 8 in a similar manner.
The guide member 6 will be pivotly attached to the shoulders 14, 20 at the pivot point 26 and 28, which in one embodiment is simply a screw with wing nut. The guide member 6 consists of a first leg 30 that extends to a slotted top portion 32, which in turn extends to the second leg 34. First leg 30 may be attached to top portion 32 via a hinge 35a and top portion 32 may be attached to second leg 34 via a hinge 35b; with the hinged attachment, the training device 2 can be disassembled and folded up for transporting the entire training device 2. The first leg 30 is pivotly attached to the leg 18, and the second leg 34 is pivotly attached to the leg 24. The slotted top portion 32 contains an elongated slot opening 36 that defines an area that the putter shaft may travel, and wherein the slot 36 contains enlarged openings 38, 40. The slotted top portion 32 contains the edge guide 42 which defines a shaft line C; as seen in FIG. 1, the shaft S of the putter 4 rests on the edge guide 42 at the point 44. The edge guide 42 is parallel with the edge 46 of the base 8, and the edge 46 defines base line B. The centerline of the slot opening 36 defines the practice line 47. FIG. 1 also depicts the anchor tee 70b. 
Referring now to FIG. 2, the putting training device 2 seen in FIG. 1 is shown and wherein the shaft S of the putter 4 is captured within the restricted area of the slot 36. In this way, the shaft of the putter 4 will be held within the predefined area that is defined by the slot 36. It should be noted that like numbers refer to like components in the various figures. In one preferred embodiment, it is possible to have a variable sized slot opening so that the width of the slot opening can be increased or decreased according to the desire of the user, as will be more fully explained later in the application.
FIG. 3 is a top view of a second embodiment of the putting training device 2, seen in FIG. 1, with a laser means 50. The edge guide 42 of the guide member 6 defines the shaft line (denoted by the line C) that is parallel with the base 8 (denoted by the line B) defined by the edge 46. The laser means 50 generates a laser beam 52 (also referred to as the target line). Lasers are commercially available from Radio Shack Inc. under the name Laser Pointer. In accordance with the teachings of the present invention, the laser means 50 will be lined up with a golf ball hole 54. The user will place a reflector 56 on the far side of the hole; please note that the reflector can also be a golf ball. As seen in FIG. 3, the reflector 56 is a plate structure, in one preferred embodiment.
The embodiment of FIG. 3 further shows the laser housing 57a (that can temporarily contain and hold the laser means 50) and the fork device 57b. The laser housing 57a is configured to receive the laser means 50. The fork device 57b is a prong type of device shaped similar to a gun-sight. The reflector 56 is centered downstream of the golf ball hole and set. As shown in FIG. 3, the laser housing 57a is situated in line with the edge 46 and the base line B. Therefore, when the laser means generates a laser beam, the laser beam will be parallel to the edge 46 and base line B. Moreover, the laser beam will be aimed through the fork device 57b to hit the reflector 56 at point 57c. The laser means 50 can be moved from housing 57a to the position in front of the edge 46, as shown in FIG. 3. In one preferred embodiment, the distance from edge 46 to the position of the laser means 50 shown in FIG. 3 is approximately 4′′ (denoted by the numeral 57d). The distance from point 57c to the center of the reflector 56 is also 4′′ (the center of the reflector 56 is shown as point 57e).
Once the laser means 50 is placed in the position shown in FIG. 3, the laser beam 52 will be reflected onto the surface of the reflector 56 at point 57e. Hence, the laser beam 52 will be parallel with the edge 46 as well as the edge guide 42. Put another way, the target line 52, shaft line C, practice line 47, and base line B are all parallel.
FIG. 4 is a top view of the putting training device 2 and laser means 50 seen in FIG. 3 along with the putter 4. Hence, the user will address the golf ball 58, as shown by the footprints 60. The putter face 62 of the putter is perpendicular to the laser beam 52, base line B, as well as shaft line C. Also, the shaft S of the putter 4 will be in contact with the edge guide 42 at point 44. The user would then stroke the ball while keeping the shaft S along the edge guide 42.
Referring now to FIG. 5, a top view of the putting training device 2 seen in FIG. 4 with the putter 4 within the slot 36 will now be described. With this embodiment, the shaft S of the putter is kept within the area defined by the slot 36. As noted earlier, it is within the teachings of the present invention that the slot 36 may be of variable size so that the width of the slot opening can be varied to train the user in keeping the shaft of the putter within the predefined parallel area, as will be more fully explained later in the application.
In one preferred embodiment, the user should practice the putting stroke without hitting either side of the slot 36. If the user continually hits the sides of the slot 36, the user should go back to the original setup along the edge guide 42 to reinforce the proper parallel stroke. When the user is keeping the putter shaft in the training guide slot 36, the user can then reduce the training guide slot 36 width by adjusting the slot 36 incrementally as the user masters the proper parallel stroke.
FIG. 6 is a side view of the putting training device seen in FIG. 1 pivoted in different angles. According to the teachings of the present invention, the user can pivot the guide member 6 to an angle that suits his or her individual putting style. This is done by loosening the wing nuts and bolts, adjusting to the proper angle, and tightening the nuts and bolts back. The guide member 6 is shown pivoted at different angles. At the position denoted by the numeral 64, the guide member 6 is at 15 degrees relative to horizontal; at the position denoted by the numeral 66, the guide member 6 is at a 90 degree angle relative to horizontal; and, at the position denoted by the numeral 68, the guide member 6 is at a 165 degree angle relative to horizontal. The arrow 69 represents the angular movement. Note that the anchor tees 70a, 70b anchor base 8 to the ground.
In FIG. 7, a perspective view of the putting training device 2 with a golfer having the putter shaft S disposed on the edge 42 of guide member 6 is illustrated. Note the tilt of the guide member 6 relative to the horizontal ground. Note that with some putters, the shaft S has steps of gradually increasing shaft diameters. Therefore, these steps could contact with the edge guide 42, and perhaps impede and/or interfere with the stroke. Hence, it is within the teachings of this invention to have a shaft sleeve concentrically disposed about the shaft area where the shaft comes into contact with the edge guide 42. FIG. 8 depicts the perspective view of the putting training device 2 with a golfer having the putter shaft S disposed within the slotted guide 36.
In operation, and referring generally to FIG. 3, the user would begin with a straight putt of approximately 9 feet. The user places the reflector 56 directly behind the target hole 54. The laser means 50 is placed within housing 57a, and the laser means 50 is turned on, and the beam is directed through the fork 57b. The entire putting training device 2 is adjusted so that the laser beam hits point 57c. The user will anchor the device 2. The user will then remove the laser means 50 and place the laser means 50 a distance from the base line B of 4 inches. At this point, the laser beam 52 is adjusted so that the laser beam strikes the center of the reflector 56 behind the target hole 54. The golfer can check to make sure that base edge 46, edge guide 42 and the laser beam 52 are all parallel. In other words, the base line B, shaft line C, practice line 47 and target line 52 should all be parallel.
The user can anchor the base with tees (denoted by the numerals 70a, 70b seen in FIG. 6) through apertures in the base 8 making sure that the laser beam stays in line. The target line 52, base line B, and the edge guide line C are parallel. Referring now to FIG. 4, the user places the putting ball 58 on the target line 52 so that the laser beam is in the center of the putting ball 58. The user would set up to the ball 58 in the user's normal putting stance. Remember that putting is individual and that there are many different setups. The user adjusts the parallel guide member 6 to the user's shaft angle. The user should again check to see if the base line B and shaft line C are still parallel.
The user should then tighten the wing nuts 28 to set the parallel guide member 6 to the user's exact shaft angle. The user will then readdress the ball 58 with the putter shaft slightly touching the edge 42. The putter face 62 should be square to the target beam 52. The user strokes the putt making sure the putter shaft S stays on the parallel guide member 6 and, in particular, on the edge 42, on both the back stroke and the forward stroke. Please note that in the most preferred embodiment, in the back stroke, the putter face 62 would open with the shaft staying on the shaft guide 42. As the golfer goes forward with the forward stroke, and at the point of the putter face 62 making contact with the golf ball 58, the putter is now square again with the golf ball 58 and the target line 52. As the forward stroke continues, the putter face 62 continues to close. Due to the contact of the shaft S to the edge 42 and the proximity of the user hands on the putter grip, the user feels the shaft S on the edge 42. It is much easier to concentrate strictly on the point where the putter shaft S touches the parallel guide member 6, and in this way, the user can feel this point on the edge 42 and concentrate on only a small area that needs to stay parallel to the target line.
In another embodiment, it is possible to use a chalk line to create a target line by simply popping a chalk line in place of the laser beam. It should also be noted that the laser can be a removable attachment to the base 8, as will be described later, or, alternatively, can be set off independently of the base as a stand-alone laser means, as seen in FIGS. 3, 4 and 5.
In a second embodiment, which is the most preferred embodiment of this application, FIG. 9 illustrates a partially exploded view of a second preferred embodiment of the putting training device 2 with attached laser means. As noted earlier, like numbers appearing in the various figures refer to like components. This preferred embodiment includes the base 8 with the first end 10 and second end 12. The first shoulder 14 is included, and wherein the first shoulder 14 contains the horizontal leg 16 that extends to the vertical leg 18, and wherein the leg 16 is attached to the first end 10. The second shoulder 20 has the horizontal leg 22 that extends to the vertical leg 24, and wherein the second shoulder 20 is also attached to the base 8.
As noted earlier, the guide member 6 is pivotly attached to the shoulders 14 and 20 at pivot points 26 and 28. The guide member 6 consist of the first leg 30 that extends to the slotted top portion 32 via hinge 35a, which in turn extends to the second leg 34 via hinge 35b. The first leg 30 is pivotly attached to the leg 18, and second leg 34 is pivotly attached to the leg 24. The slotted top portion 32 contains an elongated slot opening 36 that defines an area that the putter shaft may travel, and wherein the slot 36 contains enlarged openings 38 and 40. The slotted top portion 32 contains the edge guide 42 which defines the shaft line previously mentioned. The edge guide 42 is parallel with the edge 46 of the base 8.
FIG. 9 further depicts the laser alignment means, seen generally at 72, for aligning a laser beam. In the preferred embodiment of FIG. 9, the laser alignment means 72 will be attached to the training device 2 and, in particular, to the base 8. The laser alignment means 72 includes a “C” plate 74, and wherein the “C” plate 74 has a first leg 76 that extends to a second intermediate leg 78 which in turn extends to the third leg 80. The first leg 76 has an aperture 82 that will align with the aperture 84 so that the attachment means, such as a locking pin or bolt, can be disposed there through to attach the laser alignment means 72 to the base 8. It should be noted that legs 76 and 80 can be designed to fit into female receivers on the base 8 for attachment purposes. Returning to FIG. 9, the third leg 80 has aperture 86 that will align with the aperture 88, and wherein attachment means (such as a locking pin or bolt) can be placed in order to further attach the laser attachment means 72 to the base 8.
The laser alignment means 72 further contains a telescoping arm 90, and wherein the arm 90 has attached a laser housing 92. The telescoping arm 90 is slidably attached to the C plate 74. The laser housing 92 will hold the actual laser beam generator. As noted earlier, lasers are commercially available. FIG. 9 also illustrates a second, further extended position, namely the position seen at 94. The extendable arm positions allow for easy storage since the arm can be contracted, as well as customizing the distance needed for the individual golfer to position the golf ball in front of the training device 2.
FIG. 9 also depicts a second laser housing 96, and wherein the second laser housing 96 is attached to the telescoping arm 98, and wherein the telescoping arm 98 is slidably attached to the “C” plate 74. Additionally, FIG. 9 depicts a second position of the laser housing 96, namely the position seen as numeral 100. The second laser housing 96 is included for the situations where the golfer is a left handed player. It should be noted that the entire laser alignment means 72 can be placed onto the opposite end, such as the end 102 of base 8. Hence, in the case that a left-handed golfer wishes to use the training device 2, the golfer would simply attach the laser alignment means 72 on the opposite end 102.
Also depicted in FIG. 9 is the variable opening slot 36 wherein there is included a slidable sleeve 110. The plate can be adjusted to increase the width of the opening 36 or decrease the width of the opening 36 in an effort to train the golfer to utilize the technique of keeping the putter shaft parallel with the base line B, shaft line C, practice line 47, and the target line 52 (seen in FIGS. 3 and 4). Returning to FIG. 9, the width can be set by adjusting screws set out in the openings 112, 114.
FIG. 10 is an assembled, isometric view of the second preferred embodiment seen in FIG. 9. Note that this embodiment includes the laser alignment means 72. Therefore, the embodiment seen in FIG. 10 is for use by a right handed player. In the event that a left-handed golfer wishes to use the training device 2, the golfer simply detaches the laser alignment means 72 from the end shown in FIG. 10 and reattaches on the opposite end 102. FIG. 11 is a cross-sectional view of the variable opening slot 36 taken from line I-I of FIG. 10. FIG. 11 depicts the sleeve 110 being held in place via attachment means 116, which is a wing nut and bolt in the preferred embodiment.
