The presently disclosed subject matter is generally directed to a golf training and alignment aid, and more particularly to an improved device that allows a golfer to properly align their body and/or golf club when striking a golf ball.
The game of golf continues to grow in popularity worldwide. While millions of people play golf, the game is recognized as being inherently difficult. Accordingly, golfers are constantly looking for ways to improve their game. As a result, many golf training aids have been developed. For example, alignment rods are commonly used by golfers in an effort to improve golf ball alignment with a target (e.g., green or hole). Particularly, alignment rods are typically positioned on a support surface to indicate a target line and/or offer visual cues for other aspects of a golf swing. As a result, the golfer's stance is properly aligned with the target. However, prior art alignment rods suffer from several drawbacks. For example, alignment rods are commonly carried upright in the user's golf bag. However, prior art alignment rods independently move around the golf bag and frequently contact adjacent golf clubs and/or other items, making noise and potentially causing damage. In addition, due to movement around the golf bag, locating the alignment rods when needed requires extra time. Sleeves have been developed to prevent excessive movement of alignment rods. However, insertion and removal of the alignment rods into and from the sleeves is cumbersome and time consuming. Accordingly, it would be beneficial to provide alignment rods that overcome the shortcomings of the prior art.
In some embodiments, the presently disclosed subject matter is directed to a golf alignment device. The golf alignment device comprises an elongated base defined by opposing first and second ends separated by a length therebetween. The golf alignment device further includes a cap comprising an interior, an open end operably connected to the interior, a closed end, and a magnet positioned within the interior. The cap is positioned on the first end of the base, such that the first end is housed within the cap interior.
In some embodiments, the second end of the base is tapered or pointed.
In some embodiments, the golf alignment device further comprises a second cap positioned on the second end of the base, such that the second end is housed within an interior of the second cap.
In some embodiments, the golf alignment device has a length of about 30-60 inches, a diameter of about 0.1-1 inches, or both.
In some embodiments, the base is constructed from fiberglass, polymeric material, wood, metal, graphite, stone, or combinations thereof.

Particularly, the method comprises positioning a first alignment device adjacent to a second alignment device, such that magnetic forces couple the magnets of the first and second alignment devices together. The first and second alignment devices can be uncoupled by separating the first and second alignment rods such that magnetic forces no longer couple the magnets of the first and second alignment devices together. The first and second alignment devices each comprise an elongated base defined by opposing first and second ends separated by a length therebetween and a cap. The cap comprises an interior, an open end operably connected to the interior, a closed end, and a magnet positioned within the interior. The cap is positioned on a first end of the base, such that the first end is housed within the cap interior.

The presently disclosed subject matter is generally directed to one or more golf alignment rods that can be used as a multipurpose golf training aid, such as to teach proper golf club alignment and/or swing technique. Particularly, as shown in
Base 10 can have any desired cross-sectional shape. The term “cross-sectional shape” refers to a section cut perpendicularly to the longitudinal axis. As shown in
Base 10 can be configured with any desired length suitable for the intended instructional purpose. The term “length” as used herein refers to the longest dimension in the longitudinal direction (e.g., from first end 11 to second end 12 as shown by “L” in
The base can have any desired diameter. The term “diameter” refers to the distance of a straight-line segment passing through the center of an object, segment, or face, as shown by “D” in
Base 10 can be constructed from any desired rigid or semi-rigid material. The term “rigid material” refers to any material that does not readily bend under pressure. The term “semi-rigid material” refers to a material that can bend under the application of pressure without breaking. Suitable rigid and/or semi-rigid materials can include (but are not limited to) fiberglass, polymeric material, wood, metal (aluminum, carbon fiber, etc.), graphite, stone, or combinations thereof.
In some embodiments, the materials used to construct base 10 can be lightweight to ensure easy handling and maneuvering of the device. Thus, the base (and/or corresponding device) can have a weight of less than about 0.25-5 pounds (e.g., less than about 5, 4.5, 4, 3.5, 3, 2.5, 2, 1.5, 1, 0.5, or 0.25 pounds.
Any known method can be used to construct base 10. For example, welding, thermoforming, casting, and the like can be used. Such methods are well known in the art. In some embodiments, base 10 can be constructed to be hollow. Alternatively, the base can be solid to add weight to the device.
As set forth above, at least one end of base 10 includes cap 15, as illustrated in
In some embodiments, closed end 30 can be rounded, as illustrated in
The cap can include any desired cross-sectional shape. In some embodiments, the cap has the same or about the same cross-sectional shape as base 10. However, the presently disclosed subject matter is not limited and cap 15 can have a different cross-sectional shape relative to the base.
The cap can be configured with any desired dimensions, such as with a length of about 0.5-5 inches. Thus, the cap can have a length (L) of at least about (or no more than about) 0.2-1.5 inches (e.g., at least/no more than about 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2, 1.3, 1.4, or 1.5 inches).
Similarly, the magnet cap can have an inner diameter (D) of about 0.1-1.5 inches (e.g., at least about or no more than about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2, 1.3, 1.4, or 1.5 inches). However, the presently disclosed cap can be configured with a diameter and/or length outside the ranges set forth above. It should be appreciated that the inner diameter of the cap (e.g., the diameter of cap interior 25) is configured to be larger than the outer diameter of the base to allow first end 11 to be housed within cap opening 20 and/or interior 25. In some embodiments, the diameter of opening 20 is about 0.5-10 percent larger than the outer diameter of the base (e.g., at least/no more than about 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5 or 10 percent). However, the presently disclosed subject matter also includes embodiments larger or smaller than the stated range.
Cap 15 can be constructed from any desired material. Thus, suitable materials can be selected from (but are not limited to) rubber, silicone, vinyl, fabric, polymeric material, leather, knit fibers, or combinations thereof.
In some embodiments, cap 15 is permanently attached to first end 11 of base 10. Any known method can be used to attach the cap, such as (but not limited to) adhesive, ultrasonic seal, welding, and/or heat seal. Alternatively, the cap can be releasably attached to the base using any known mechanism, such as (but not limited to) pressure fit attachment, snap fit attachment, interference fit, screw threads, and/or the use of mechanical closures (e.g., pins, screws, and the like).
Cap interior 25 includes magnet 35, as shown in
Magnet 35 can be constructed from any material that can be magnetized. For example, the magnet can include (but is not limited to) iron, cobalt, nickel, copper, platinum, aluminum, and/or alloys thereof.
Magnet 35 can have any desired magnetization grade, such as (but not limited to) about N38-N52 (e.g., a pull force of about 4 pounds to about 11 pounds). The term “pull force” refers an action or stress resulting from applied forces that cause or tend to cause two objects to move relative to each other in a direction perpendicular to their plane of contact. In some embodiments, the “pull force” is the amount of force needed to pull on a magnet to move it away from a steel surface (e.g., a 2 inch thick, ground, flat steel plate). Thus, the magnet can have a pull force of about 4, 5, 6, 7, 8, 9, 10, or 11 pounds. However, magnets with greater or less pull force are also within the scope of the presently disclosed subject matter. Magnetization grades measure the strength of a particular magnet. In general, a higher number indicates a stronger magnet. The number represents the strongest point on the magnet's demagnetization curve (also called “BH curve”).
The magnet can be configured in any desired size and shape, so long as it can fit within cap interior 25. Thus, the magnet can be cylindrical, rounded, rectangular, etc., with a diameter less than the diameter of cap opening 20.
The magnet can be housed within cap interior 25 using any known method, such as (but not limited to) the use of adhesive, epoxy, welding, molding, an internal housing, and the like. In some embodiments, more than one magnet can be accommodated within the interior of cap 15. Magnet 35 is arranged within cap 15 such that each magnet is magnetically attracted to a corresponding magnet positioned in a second alignment rod. The magnets of adjacent alignment rods are automatically attracted to each other, which assists in the neat and orderly storage of without any additional covers and sleeves.
After the magnet is positioned within cap interior 25, the cap can be assembled on first end 11 of base 10, as shown in
In some embodiments, a second cap 16 comprising magnet 35 can additionally be positioned on the second end of the base, as shown in
The base and/or cap can be constructed in any desired color, such as one or more of white, black, yellow, green, red, purple, blue, grey, silver, orange, etc. Similarly, the base and cap can include one or more patterns, such as (but not limited to) stripes, stars, dots, shapes, waves, and the like. The base and cap can further include words as desired by the user.
In use, the magnet housed at cap end 30 allows at least two alignment rods to be coupled together due to magnetic attraction. As shown in
When the user desires to use one or more alignment rods 5, he simply removes them from the golf bag as a pair (resulting from the magnetic attraction of magnets 35). The golfer applies light pressure to separate the alignment rods, placing them into proper position on the ground. The golfer can then use them as desired to improve his alignment to the ball. For example, the golfer can place the alignment rods on the ground parallel to each other. A first alignment rod 5a can be positioned along the target line T next to the golf ball, while a second alignment rod 5b is positioned along the golfer's toe line. The golfer can then get into his stance with proper alignment (such that golf club 50 is in the correct position to hit ball 55 towards a target). It should be appreciated that a golfer can use one or more alignment rods for any of a wide variety of training exercises. For example, in some embodiments, a rod can be vertically tucked into the elbow of the golfer with one end on the ground. In this way, proper body rotation can be controlled.
After the golfer has used the pair of alignment rods, he simply picks the rods up, and advances the caps towards each other until the magnetic attraction is great enough to couple the rods together. The golfer can then place the rods in a golf bag or to the side until needed again.
In some embodiments, the magnetic attraction of magnet 35 is great enough to allow the golfer to use a first alignment rod to pick up a second alignment rod from the ground. For example, the user can grasp first alignment rod 5a and position it such that cap end 15 nears the cap end of second alignment rod 5b lying on a support surface 40 (e.g., a putting green), as shown by Arrow A in
In some embodiments, more than two alignment rods can be used at a time. Alternatively, a single alignment rod can be used for a desired exercise. In such cases, the user can apply slight pressure to separate one alignment rod 5 from a pair. Once separated, the user can position the alignment rod as desired. After use, the golfer can re-pair the alignment rods by joining the cap ends such that the magnets attract and keep the pair attached.
The presently disclosed subject matter can also include one or more optional accessories that can be removably coupled with an alignment rod. Specifically, accessory 70 can include magnet 75 that is attracted to alignment rod magnet 35. Magnet 75 can be attached to the accessory using any known method, such as (but not limited to) the use of sewing, adhesive, welding, and the like. Magnet 75 can include any material that is attracted to alignment rod magnet 35. Thus, magnet 75 can be constructed from iron, cobalt, nickel, copper, platinum, aluminum, and/or alloys thereof. The magnet can be positioned at any desired location on the accessory (e.g., front, rear, side, top, bottom, interior, and/or exterior).
Suitable accessories can include (but are not limited to) one or more golf gloves 71, golf club headcover 72, putter cover 73, and range finder 74, as shown in
In use, a golfer can temporarily attach accessory 70 to an alignment stick via magnetic connection between magnets 75, 35. For example, a golfer can remove an accessory (e.g., golf club headcover 72) and temporarily attach it to the magnet of one or more alignment sticks 5 through magnetic attraction. The accessory is then conveniently accessible when needed (e.g., when the golfer desires to reapply the headcover to a golf club). At any time, the golfer can apply pressure to remove the accessory from the alignment rod, breaking the magnetic attraction between magnets 75, 35. The accessory can then be placed in the storage position (e.g., on a golf club, etc.).
Often the accessory is simply tossed to the ground or in the back of a golf cart, increasing the likelihood that the accessory is misplaced or damaged. The disclosed alignment rod can therefore prevent and or decrease the likelihood of damage to a wide variety of accessories 70.
The disclosed invention affords many improvements over the prior art. Specifically, the disclosed alignment rods allow optimized access of the alignment rods in a golf bag.
Advantageously, the disclosed alignment rods can be utilized in all capacities and functions of traditional golf alignment rods.
The disclosed alignment rods can be stored upright in a golf bag and automatically secured together through magnetic attraction of the rod caps.
The disclosed alignment rods are simple and effective training aids that can be used by a golfer in drills to practice virtually every aspect of the game of golf.
