1. Field of the Invention
The present invention relates in general to golf swing aids, and more particularly to golf training glasses. These are particularly designed to improve a golfer's putting stroke and golfer's swing.
2. Background Art
Devices to help golfers improve their swing and ball connection have been in the planning and development stages for years but with only limited success. In particular many of these devices have taken the form of spectacles or glasses to be worn by a golfer.
These glasses or spectacles are generally designed to minimize head movement during the swinging of a golf club, provide a shot line, or a combinatino of both. However existing designs have only achieved limited success in terms of functionality and use due to the fact the inter-pupillary distance or PD height (ie the distance between the centre of the pupils), which is different for each end-user, was not taken into consideration and accommodated for.
For instance, each of Fabanich, U.S. Pat. No. 991,849, Palumbo. U.S. Pat. No. 3,264,002 and McMurdo, U.S. Pat. No. 2,009,700 are directed to eye glasses for use as training devices having one or more horizontal lines extending across at least a portion of the lenses for defining a visual path from the ball to the hole. Fabanich further includes a small gap in one of the horizontal lines in which to locate the ball, and a sight guide which may be adjusted between positions closer to and farther from a golfer's eye.
In contrast Palumbo includes an extension bar which attaches to the frame of a pair of glasses for visual alignment of the ball with a target.
Other prior art golf training glasses include Engesser, U.S. Pat. No. 3,487,549, Underhill, II, U.S. Pat. No. 3,871,104, Krupicka, U.S. Pat. No. 4,251,107 and Griffith, U.S. Pat. No. 5,489,953, disclose eyeglasses having one or more horizontal lines extending across at least a portion of the one of the lenses, and one or more vertical elements positioned proximate the horizontal lines in at least one lens. The combination of the vertical and horizontal elements allows alignment of a target, such as a ball, in the cross hairs. Further, the vertical portion may function to help a golfer align a golf club such as a putter, while the horizontal line may provide a guide for the ball path.
Another prior art golf swing training glasses is Anthony Basil McMahon U.S. Pat. No. 6,558,266. His golf training glasses use a frame, a pair of lenses associated with the frame, and a sight guide associated with each lens. The sight guide includes an upper guide bar and a lower guide bar. The upper and lower guide bars extend from the right side of the lens, to the left side of the lens, the upper guide bar is separated at least partially from the lower guide bar to form a shot pathway between the upper mad lower guide bars. The upper and lower guide bars partially merge into one on the right and left sides of the lenses to form a shot pathway to focus a shot line for the golfer. Additionally the sight guide further includes a ball placement locator for positioning the shot pathway, and a foot placement guide to help align a golfer's stance with the ball, the shot pathway and the club path. However the sight guides and/or guide bars are permanent features and are not adjustable up and down vertically to take account of different PD heights for each golfer's which is critically important.
As stated above these and other prior art devices have only worked in a limited manner, due to the fact the PD height of each user was not taken into consideration or accommodated for. It is therefore desirable to provide an improved pair of truly functional golf training glasses to help shave strokes of a golfer's game. In particular, while prior devices have provided cross hairs for location of a ball and a horizontal line to assist in locating a ball path, none off these prior art references have provided a method by which a golfer can adjust the PD line for both the right and left eye separately and independent of each other. On the other hand, our design and device allows the sight guides to adjust up and down independently to account for different PD heights of each end-user.
Framing the in the pupil of each eye according to PD heights of each eye of different end-users (golfers) will align both eyes properly and thereby form a truer shot pathway. This function is critical (and the essential distinction of our invention from all other previously granted patents and known golf swing aid devices which makes it unique and novel) because each user has a different PD height and by being able to adjust the sight guides up and down vertically this helps to frame the pathway for each golfer as the PD is different for each user.
The present invention is directed to golf training glasses that help assist a golfer's swing; mainly in the putting stroke. The golf glasses will have two frames (an inner and outer), but there will be no need for lenses. The inner frame with its features will act as a base or support frame for the outer frame which with its features will act as an eye gauge.
The eye gauge will have two separate sight guides, one for the left eye focus and one for the right eye focus, running horizontally across the view plane from left to right and right to left respectively towards the nose area. Each sight guide will be designed as hollowed rectangles or cylinders and thus will have an upper ridge and a lower ridge separated by a hollowed area of at least three millimeters to form a middle sight line or channel or pathway between the upper and lower ridges.
In a preferred embodiment the sight guides will have a middle opening or hallowed area of at least three millimeters wide. A middle sight line or channel or pathway will be formed between the upper and lower ridges. When looked through this opening or hallowed area will act as an eye sight line or channel or pathway for the golfer to focus on the ball, club and hole. This will allow the putter to follow back in a straight line and then forward in a straight line.
The sight guides will separately have the ability to be adjusted up and down vertically by various mechanisms including but not limited to a threaded post and tracking wheel. Each guide will be able to be move and be adjusted independently from the other on its own track. The reason each track moves on its own is because both eyes are different heights and each pupil has its own PD line (inter-pupillary distance). By moving each guide independently you can create a depth perception that is catered to each eye individually.
The sight guides can be adjusted and move freely vertically by various mechanisms including a threaded screw posts and tracking wheel system. Rotation of the tracking wheel will allow each sight guide to move up and down in slow increments to help you line each eye up so that they are looking through the middle of the slot. This helps in creating binocular vision, so that each eye works together to create one sister line to take the putter back in a smooth stroke and on a straight plane.
If the golfer so desires the outer frame or sight gauge will have the ability to flip up and out of the out of the golfer's field of vision when the device is not being used or detached completely by means of a male/female hinged clip on the brow of the inner and outer support frame.
While this invention is susceptible of the embodiment in many forms, they are shown in the drawings and will be described in detail in several specific embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention, and is not intended to limit the invention to the embodiments illustrated.
For example the sight guides 22 & 23 can be adjusted up and down to account for different PD heights of end-users by means of a mechanism system which includes, but is not limited to, a threaded guide post or screw 14 & 15 and a tracking wheel 12 & 13. This system could be changed by having 12 & 13 placed on top of 14 & 15 respectively and thereby having the ability to adjust 22 & 23 up and down from the top of the outer frame. Another mechanism system could include a slider track with an indexed notched locking or ratchet system and various other systems to adjust the sight guides up and down.
There is shown in
On the base frame 3, we have 27 & 28 which are the support arms, left and right side respectively, to hold the device onto the wearers head. Arms 27 & 28 connect to 3 at a hinge, such that the arms can fold inwardly for storage of glasses as is standard.
We also have 4 attached to 3 by 5. Moreover, we also have 22 which is the right-side sight guide for the right eye. This is attached to 4 by 14 which is the threaded guide post or screw that lets 22 move up and down 14 by turning 12 which is the tracking wheel that moves 22 to the frame in the pupil of the right eye.
Also we have 23 which is the left-side sight guide for the left eye. This is attached to 4 by 15 which is the screw or threaded guide post that lets 23 move up an down 15 by turning 13 which is the tracking wheel that moves 23 to frame in the pupil of the left eye.
Also we have 7 which is the bridge support that helps hold the inner base frame 3 onto the nose of the wearer.
The present invention dramatically improves all prior golf swing aid devices by providing a sighting aid for the golfer. This device, in particular the sight guides 22 & 23 when properly adjusted to account for different PD heights of end-users (golfers), can be used to align both eyes along an optical sight line or viewing channel which allows the putter/club, ball and hole to be framed in together enabling the golfer to take the putter/club back in a straight line and forward in the same true line to make a good fluid stroke and connection on the golf ball and send it to the hole on the green.
Sight guide 22 is the sight guide for the right eye which has the open slot channel to frame in the putter/club, ball and hole. The sight guide 22 moves up and down along 14 which is the screw or threaded guide post that allows 22 to be adjusted by being turned by 12 which is the tracking wheel that makes 22 move up and down along 14. This allows 22 to be adjusted to get the correct height to frame in the pupil for the right eye.
Sight guide 23 is the sight guide for the left eye which has the open slot channel to frame in the putter/club, ball and hole. 23 moves up and down along 15 which is the screw or threaded guide post that allows 23 to be adjusted by being turned by 13 which is the tracking wheel that makes 23 move up and down along 15. This allows 23 to be adjusted to get the right height to frame in the pupil for the left eye.
