CROSS-REFERENCE TO RELATED APPLICATIONS 
   This patent application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/938,889 filed on May 18, 2007 and entitled “Training Device for Golf,” the disclosure of which is incorporated by reference as if fully rewritten herein. 

   BACKGROUND OF THE INVENTION 
   The described invention relates in general to a training device for use with the game of golf, and more specifically to a golf club head for use with a putter, wherein the golf club head includes at least two independently adjustable guide rods that extend through the body of the putter parallel to the central longitudinal axis of the club head. 
   Training clubs and other training devices for use in teaching the fundamentals of the game of golf are as common as the game itself. While many of these devices are somewhat useful for their intended purpose, few golf training devices are designed for use by people with significant physical disabilities. Because golf is a highly visual game, people who suffer from blindness or other vision problems are often left without any means by which to learn, train for, and enjoy the game of golf. Therefore, there is an ongoing need for training devices for use in the game of golf that are designed for individuals suffering from blindness or other significant vision problems. 
   SUMMARY OF THE INVENTION 
   The following provides a summary of certain exemplary embodiments of the present invention. This summary is not an extensive overview and is not intended to identify key or critical aspects or elements of the present invention or to delineate its scope. 
   In accordance with one aspect of the present invention, a club head for use with a putter for the game of golf is provided. This golf club head includes: a body having a center longitudinal axis passing lengthwise therethrough; a first guide rod mounted within and passing through the body parallel to the center longitudinal axis and on one side thereof, wherein the first guide rod is selectively positionable lengthwise within the body; and a second guide rod mounted within and passing through the body parallel to the center longitudinal axis and on the opposite side thereof, wherein the second guide rod is selectively positionable lengthwise within the body. 
   In accordance with another aspect of the present invention, a putter head with integrated, sliding guide rods is provided. This putter head includes: a body having a center longitudinal axis passing lengthwise therethrough, wherein the body is adapted to receive a golf club shaft and a detachable club face; a first guide rod mounted within the body parallel to the center longitudinal axis and on one side thereof, wherein the first guide rod is selectively positionable lengthwise within the body; a second guide rod mounted within the body parallel to the center longitudinal axis and on the opposite side thereof, wherein the second guide rod is selectively positionable lengthwise within the body; and mechanical means for securing each guide rod within the body at a desired position.

   DETAILED DESCRIPTION OF THE INVENTION 
   Exemplary embodiments of the present invention are now described with reference to the Figures. Reference numerals are used throughout the detailed description to refer to the various elements and structures. In other instances, well-known structures and devices are shown in block diagram form for purposes of simplifying the description. Although the following detailed description contains many specifics for the purposes of illustration, a person of ordinary skill in the art will appreciate that many variations and alterations to the following details are within the scope of the invention. Accordingly, the following embodiments of the invention are set forth without any loss of generality to, and without imposing limitations upon, the claimed invention. 
   The present invention relates to a training device for use in the game of golf. As previously indicated, a first general embodiment of this invention provides a club head for use with a putter; a second general embodiment of this invention provides a putter head that includes integrated guide rods; and a third general embodiment of this invention provides a training device for use with the game of golf. With reference now to the Figures, one or more specific embodiments of this invention shall be described in greater detail. 
   As shown in  FIGS. 1-5 , an exemplary embodiment of the present invention includes a putter head  10  that further includes a body  12  having at least two guide rods  70  and  72  mounted therein. In the exemplary embodiment shown in the Figures, body  12  is roughly triangular in shape; however, other shapes and geometric configurations are possible. Body  12  includes mounting aperture  14 , which is adapted to receive the bottom portion of club shaft  80 . Recess  16  is formed in the front surface of putter head  10  and is adapted to receive face plate  60 , which may be removed and replaced with an alternate face plate, if desired. A bore  18  and a bore  20  are formed in body  12  and receive mounting bolts  50  and  52  respectively, both of which are used to attach face plate  60  to body  12 . As best shown in  FIG. 3 , outer bores  22  and  24  are formed in body  12  to receive guide rods  70  and  72  respectively at one position within body  12 , and inner bores  26  and  28  are formed in body  12  to receive guide rods  70  and  72  respectively at another position within body  12  which is closer to the central longitudinal axis thereof. Mounting apertures  30  and  32  correspond to the placement of outer bores  22  and  24  respectively and receive first tightening screw  54  and second tightening screw  56  respectively when guide rods  70  and  72  are mounted within outer bores  22  and  24 . Mounting apertures  34  and  36  correspond to the placement of inner bores  26  and  28  respectively and receive first tightening screw  54  and second tightening screw  56  respectively when guide rods  70  and  72  are mounted within inner bores  26  and  28 . Outer channels  38  and  40  correspond to the placement of outer bores  22  and  24  respectively and receive guide rods  70  and  72  respectively when the guide rods are mounted within outer bores  22  and  24 . Inner channels  42  and  44  correspond to the placement of inner bores  26  and  28  respectively and receive guide rods  70  and  72  respectively when the guide rods are mounted within inner bores  26  and  28 . 
   Guide rods  70  and  72  are typically manufactured from carbon fiber or another suitably strong and relatively lightweight material or combinations of materials. These rods are typically rounded at each terminal portion thereof. In the exemplary embodiment, guide rods  70  and  72  are about 6.0 inches (15.24 cm) in length, although other lengths (e.g., 4-10 inches) are possible based on user preference or other training factors. Guide rods  70  and  72  are inserted into body  12  through bores  22  and  24  or  26  and  28 , and positioned according to user preference or trainer preference by simply sliding the rods within channels  38  and  40  or  42  and  44 . Screws  54  and  56  (see  FIG. 3 ) are then manually tightened into body  12  to secure guide rods  70  and  72  in the desired position and prevent unwanted movement when the putter is in use. To move guide rods  70  and  72 , screws  54  and  56  are simply loosened and then re-tightened when the desired position for guide rods  70  and  72  is achieved. As shown in  FIG. 5 , guide rods  70  and  72  may be moved and positioned completely independent of one another. Guide rods  70  and  72  may also be removed from body  12  when the user or trainer desires to use putter head  10  without the guide rods. 
   As shown in the Figures, guide rods  70  and  72  are mounted within putter head  10  on either side thereof and may be moved forward or backward, independently of one another, based on the relative positions desired by the user of the training device and/or their coach or trainer. These guide rods provide a guiding or aiming means to the user of the club such than when the club swings forward or backward, the guide rods essentially track or follow the contours of the surface on which the user is putting. The guide rods basically prevent the user of the club from incorrectly tilting or turning the club face or the entire club head in the wrong direction. Substantially maintaining the golf club head in a single directional plane typically results in a golf shot that is much more likely to hit the intended target, i.e., the cup. In the exemplary embodiment shown in the Figures, the guide rods are generally cylindrical and are weighted to enhance the pendulum swinging effect. In other embodiments, the guide rods may include different configurations and different weights. For example, in another embodiment (not shown in the Figures), the forward ends of the guide rods are directed outward to form a Y-shaped channel. Numerous other variations are possible and are contemplated by the present invention. 
   In addition to the guide rods described herein, the golf club head of the present invention includes several features that are intended to create and reinforce a correct swinging/putting motion in the user of the device based on feel rather than vision. For example, as shown in the Figures, a significant portion of the weight of the club head is distributed lengthwise along the center longitudinal axis thereof such that the club head naturally swings in a relatively straight backward to forward manner. The overall length of the club head may be increased and more weight added thereto to further enhance this aspect of the club&#39;s performance. Also, in the exemplary embodiments discussed herein, the aperture that is adapted to receive a hozzle and shaft is “centrally” placed on the club head and is generally aligned with the extended back portion of the club head, as shown in the Figures. This configuration further encourages the development of a correct swinging motion. In other embodiments, the club shaft may include one or more vibration damping means for further enhancing accuracy. 
   A primary objective of the golf training device of the present invention is to create a certain “muscle memory” in the user that will allow the user to swing and/or putt in a far more consistent and accurate manner, even when the guide rods are not being used. Over the course of many swinging or putting repetitions, the unique features of the present invention will presumably create the desired muscle memory and the correct swinging motion will likely become instinctual to the golfer who has trained with this club. The user and/or coach may also utilize a golf ball  90  having a painted stripe thereon (see  FIG. 5 ) for further encouraging and reinforcing a correct swing or putting motion. Because the club head of the present invention is intended for use with or without guide rods  70  and  72 , guide lines  74  and  76  (see  FIGS. 1 ,  2  and  5 ) may be included on the upward facing surface thereof to provide further means by which to correctly properly align the putter head with a golf ball. As will be appreciated by one of ordinary skill in the art, the golf club described herein and all components thereof can be manufactured, fabricated, or otherwise created using known techniques and methods. The exterior of the putter head  10  may be anodized to provide specific colors or color combinations based on user preference or aesthetic considerations. 
   While the present invention has been illustrated by the description of exemplary embodiments thereof, and while the embodiments have been described in certain detail, it is not the intention of the Applicant to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will readily appear to those skilled in the art. Therefore, the invention in its broader aspects is not limited to any of the specific details, representative devices and methods, and/or illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the spirit or scope of the applicant&#39;s general inventive concept.
