Description of the Preferred Embodiment
With reference now to the drawings, and in particular, to FIG. 1-6 thereof, the preferred embodiment of the new and improved laser putter embodying the principles and concepts of the present invention and generally designated by the reference number 10 will be described.
Specifically, it will be noted in the various Figures that the device relates to a new and improved laser putter for practicing aid for golfers which projects a visual sight line to aid in lining up a putt. In its broadest context, the device consists of a golf putter, a laser, two flat mirrors, and a convex mirror.
The device 10 contains a golf putter 12 having a putting head 14, a shaft portion 16, and a hollow handle portion 18. The hollow handle portion 18 has a padded outer layer 20 secured thereto. The hollow handle portion 18 has a removable end portion 22. The hollow handle portion 18 has an upper chamber 24 and a lower chamber 26 therewithin. The upper chamber 24 is accessible from the removable end portion 22. The upper chamber 24 and the lower chamber 26 are separated by a retaining wall 28. The retaining wall 28 has a through hole 30. The hollow handle portion 18 has an aperture 32 formed therein extending outwardly of the lower chamber 26. The lower chamber 26 has a triangular wedge 34 secured therein below the retaining wall 28. The triangular wedge 34 has a front surface 36 radially disposed from the aperture 32. The front surface 36 of the triangular wedge 34 is at forty-five degree angle from the hollow handle portion 18. The hollow handle portion 18 has a conical shaped support ledge 38 extending diagonally downward from the padded outer layer 20 thereof. The conical shaped support ledge 38 has a back surface 40 radially disposed from the aperture 32. The back surface 40 is at a forty-five degree angle from the hollow handle portion 18.
A laser 44 is secured within the upper chamber 24 of the hollow handle portion 18. The laser 44 generates a beam 46 outwardly of the through hole 30 of the retaining wall 28 of the hollow handle portion 18. The laser 44 has an activation mechanism extending outwardly within the padded outer layer 20 of the hollow handle portion 18 to be activated or de-activated by a user. The activation mechanism comprises an on/off push button switch 47 protected by a shield 48 within the padded outer layer 20 of the hollow handle portion 18. The on/off push button switch 46 having sensor wires 50 extending inwardly of the hollow handle portion to couple with activation switches 52 that serve to activate or de-activate the beam 46 of the laser 44. When activated, the laser 44 sends a beam 46 down through the through hole 30 of the retaining wall 28 and into the lower chamber 26. The laser 44 can be removed from the upper chamber 24 of the hollow handle portion 18 through the removable end portion 22 thereof.
The device 10 contains two flat mirrors. A first mirror 56 is secured to the front surface 36 of the triangular wedge 34 of the hollow handle portion 18. A second mirror 58 is secured to the back surface 40 of the support ledge 38 of the hollow handle portion 18. When the laser 44 is activated, the beam 46 is directed into the through hole 30 of the retaining wall 28 and into the lower chamber 24 where the first mirror 56 directs the beam 46 outwardly of the aperture 32 of the hollow handle portion. The beam. 46 then contacts the second mirror 58 which directs the beam 46 downwardly.
The device 10 contains a convex mirror 62 secured to the padded outer layer 20 of the hollow handle portion 18 downwardly of the conical shaped support ledge 38 thereof. When the laser 44 is activated, the convex mirror 62 receives the beam 46 after it contacts the second mirror 58 and directs the beam 46 downwardly. The convex mirror 62, in turn, projects the beam 46 out to a location forwardly of the ball being putted, along a line perpendicular to the putting head 14 of the golf putter 12. This provides a golfer with a line of sight to effectively practice putting.(See FIGS. 2-3)
The present invention is a putting practice aid for golfers which projects a visual sight line to aid in lining up a putt.
This device 10 employs a small low power laser 44 of the type used for a pointing device in presentations. It either attaches to the putter shaft with hook and loop straps, or could be incorporated into the design of the club and enclosed inside the handle 18. The beam 46 is pointed downward along the shaft 16, and is directed forwardly of the putting head 14 through a single mirror or series of mirrors. A single convex mirror 62 is used for the externally mounted device, while the one incorporated into the handle 18 requires a total of three mirrors, two flat ones 56,58 and the third a convex one 62. These are oriented and affixed to the putter 12 at exact locations to bring the laser 44 beam 46 to a location forwardly of the center of the putting head 14. The final mirror is convex in shape, and projects the beam 46, to a location along a line 66 perpendicular to the putting head 14 and onto the ground.
The laser's 44 beam 46 is directed either onto the single convex mirror 62, or onto the series of mirrors 56,58 and finally onto the convex mirror 62. The surface of this last mirror 62 causes the beam 46 to be formed into a line that shines down onto the ground at a location along a line 66 perpendicular to the face on the putting head 14.
Ideal for practicing putting, this golf putter 12 gives a very accurate indication of the club alignment with relation to the cup. The weight is negligible and does not affect the balance or performance of the putter 12.
As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modification and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modification and equivalents may be resorted to, falling within the scope of the invention.
