There is provided a golf club of the iron type wherein the hosel is formed intermediate the heel and toe portions of the club with the front face of the club head having a substantially uniform height from the toe portion to the heel portion. This arrangement provides a greater latitude of error when the ball is struck off center.
There is provided a golf club of the iron type wherein the hosel is formed intermediate the heel and toe portions of the club with the front face of the club head having a substantially uniform height from the toe portion to the heel portion. This arrangement provides a greater latitude of error when the ball is struck off center.
Description
The present invention relates to golf clubs and more particularly, relates to golf clubs of the iron-type.
Over the years, there have been many different approaches ta~en to the design and construction of iron type golf clubs has been taken. Generally the golf club heads have, however, remained substantially uniform wherein there is a front face, a back face, a sole, a toe portion, a heel portion and a hosel portion. Conventionally, the hosel is formed at the heel of the club. The front face of the club head (and the rear face) are normally designed such that the face has a greater height near the toe portion than near the heel portion.
When hitting a golf shot, a great deal of skill is required and missed shots are frequent, particularly among those of relatively lesser skill. Thus, if the ball is not struck squarely on the "sweet spot" of the club, a misdirected shot will occur. In other words, when the ball is hit either near the heel or toe portions of the club, a poor shot normally results.
It is an object of the present invention to provide a golf club head of the iron-type which provides a larger margin of error compared to a conventional golf club when the ball is hit near the toe or heel areas of the club face.
According to one aspect of the present invention, there is provided an improved golf club of the iron type which comprises a shaft and a club head, the club head having a toe portion, a heel portion, a hosel, a front face extending between the toe and heel portions with the height of the front face being substantially uniform between the toe ; 1 8 ~
and heel portions, and with the shaft being secured to the hosel.
In a further aspect of the invention, there is provided a golf club of the iron type which comprises a shaft and a club head, the club head having a toe and heel portion, a hosel adapted to receive the shaft, the hosel being formed intermediate the toe and heel portion of the club head.
In greater detail, according to one aspect of the present invention, the club head is designed such that the hosel, which receives the shaft, is located intermediate the toe and heel portions. In so doing, shots hit near the heel portion no longer will suffer interference from the hosel of the club head. In conventional golf clubs, the hosel is located and indeed forms a portion of the heel portion and as will be discussed in greater detail herein below, a ball hit near this portion can result in an inaccurate shot.
According to this aspect of the present invention, the hosel is located substantially mid-way between the toe and heel portions although it will be understood that a certain degree of variation may be accommodated. The hosel is preferably situated such that the shaft joins the hosel rearwardly of the face of the club head. The distance between the face and the shaft may vary depending upon the particular club. Thus, in the case of the lower irons, the shaft may not need to be spaced as large a distance as is the case with the higher irons since the point of contact with the ball (near the top of the face) is different.
In a further aspect of the present invention, the face of the club head is designed such that the height

According to one aspect of the present invention, there is provided an improved golf club of the iron type which comprises a shaft and a club head, the club head having a toe portion, a heel portion, a hosel, a front face extending between the toe and heel portions with the height of the front face being substantially uniform between the toe ; 1 8 ~

In a further aspect of the invention, there is provided a golf club of the iron type which comprises a shaft and a club head, the club head having a toe and heel portion, a hosel adapted to receive the shaft, the hosel being formed intermediate the toe and heel portion of the club head.
In greater detail, according to one aspect of the present invention, the club head is designed such that the hosel, which receives the shaft, is located intermediate the toe and heel portions. In so doing, shots hit near the heel portion no longer will suffer interference from the hosel of the club head. In conventional golf clubs, the hosel is located and indeed forms a portion of the heel portion and as will be discussed in greater detail herein below, a ball hit near this portion can result in an inaccurate shot.
According to this aspect of the present invention, the hosel is located substantially mid-way between the toe and heel portions although it will be understood that a certain degree of variation may be accommodated. The hosel is preferably situated such that the shaft joins the hosel rearwardly of the face of the club head. The distance between the face and the shaft may vary depending upon the particular club. Thus, in the case of the lower irons, the shaft may not need to be spaced as large a distance as is the case with the higher irons since the point of contact with the ball (near the top of the face) is different.
In a further aspect of the present invention, the face of the club head is designed such that the height
2 0 ~ 3 thereof is substantially uniform extending from the heel to the toe portion of the club. This provides a larger hitting surface and also permits a greater margin of error particularly when the ball is hit what was the traditional heel portion of the club. Thus, since the height of the face near the heel extends higher than in a conventional club, a shot wherein the ball is contacted near the upper portion of the face proximate the heel will result in a more accurate shot. This is particularly the case with the higher irons such as a nine iron or wedge wherein the club head tends to get under the ball to a greater extent than with the lower irons.
The attachment of the shaft to the club head at a point intermediate of the toe and heel portions could also permit the engineering of a larger "sweet spot" than may otherwise be the case. It has long been proposed in the past to weight club heads in various manners so as to provide larger sweet spots. However, given certain methods of manufacture, the provision of this type of weighting was somewhat limited due to the inherent requirements with the hosel at the heel portion of the club head. With the club head of the instant invention, the center rotation of the club head is rotated adjacent the shaft which is at the center of the face rather than at one side thereof. Thus, a shot which is hit somewhat off center of the club will cause a lesser rotation of the club head than would otherwise be the case.
The club head of the present invention can be manufactured by conventional processes known in the art such 2 ~ 8 3 as investment casting. Any suitable material can be selected including material such as stainless steel and the like.
Similarly, conventional manufacture would include the provision of grooves along the face of the club head.
Having thus generally described the invention, reference will be made to the accompanying drawings illustrating an embodiment thereof, in which:

Referring to the drawings in greater detail and by reference characters thereto, a conventional golf club 10 of the iron type is illustrated in Figures 2 and 4.
The conventional golf club head 10 includes a front face 12 and a rear face 14 with a bottom sole 16. Club 10 has a toe portion 18 and a heel portion 20 which merges with a hosel 22 to which the shaft of the club is attached. The front face 12 includes a plurality of grooves 24 as is conventional in the art.
As may be seen from Figure 2, adjacent the toe portion 18, the club head has a height "Y" while adjacent the heel portion 20 the club head has a height "y" wherein Y > y.
This is a substantially conventional arrangement utilized for most known golf club irons. Also, as shown in Figure 2, the club head has a width L which is the total overall width from toe 18 to heel portion 20; the effective hitting width is that indicated by reference character X.
Referring to Figures 1 and 3, a golf club head 30 according to the present invention is illustrated. Golf club head 30 includes a front face 32 and a rear face 34 and has a sole portion 36 extending along the bottom. Club head 30 also includes what is designated a toe portion 38 and a heel portion 40 with a hosel 42. Grooves 44 are provided on front face 32.
As may be seen from the drawings, hosel 42 is located intermediate toe and heel portions 38 and 40 respectively and the heights "Y" of both toe portion 38 and heel portion 40 are identical. All of the grooves 44 are of substantially uniform length and extend over the effective 2 ~ 8 3 hitting area of front face 32 with the distance "X" being equal to the distance "X" of the prior art clubs. Similarly, the overall width of the entire club face is substantially equivalent to that of a conventional golf club as shown in Figure 2.
Reference will now be made to the Figures 3 and 4 which illustrate the differences between the prior art and present club heads on a golf ball near the heel portion of the club head. Thus, as shown in Figures 4 and 6, when a golf ball 50 (shown in dotted lines) is struck close to the heel portion 20 of club head 10, not only does the ball 50 contact front face 12 at the point of impact designated by reference P, it can also contact the hosel portion at point 52. As shown by arrow 54, this will cause the ball 50 to move in a line off center to the intended direction. This can happen both if the ball is hit on the lower portion of the front face 12. When the ball 50 is hit at the upper portion (such as can occur with a wedge) the height "y" of the club head is not sufficient to provide full control over the ball.
As shown in Figure 3, since the front face 32 of club head 30 has a constant height "Y'~, and since the hosel portion 42 is located between the toe portion 38 and heel portion 40 and rearwardly of the front face 32, the point of impact P results in a ball making clean contact with the front face 32 and a better shot results.
Figure 3a illustrates a further club of the iron type but a "lower" iron such as 3 iron. As shown therein, the same results occur. As may be seen from Figures 3 and 2 ~ 8 '~
3a, the distance "G" between the hosel and club face 32 is slightly greater with the higher iron.
Figures 7 and 8 compare the impact of conventional head 10 and conventional 30 of the present invention when the ball is hit adjacent the toe portion. As shown in Figure 7, when the ball contacts club head 10 at point P, there is effective distance R from hosel or shaft portion causing the club head to open or rotate from the desired plane by an angle A. This results in the ball going off the intended court as indicated by arrows 58.
As shown in Figure 8, the same point of impact P on club head 30 of the present invention results in a distance _ from the point at which the club head will rotate and consequently, the angle the club head opens is reduced to _.
This results in the ball taking a direction indicated by arrows 60 which is half the error of that which would occur in the case of conventional club head 10 as shown in Figure 7.
It will be understood that the above described embodiment is for purposes of illustration only and that changes and modifications may be made thereto without departing from the spirit and scope of the invention.
The attachment of the shaft to the club head at a point intermediate of the toe and heel portions could also permit the engineering of a larger "sweet spot" than may otherwise be the case. It has long been proposed in the past to weight club heads in various manners so as to provide larger sweet spots. However, given certain methods of manufacture, the provision of this type of weighting was somewhat limited due to the inherent requirements with the hosel at the heel portion of the club head. With the club head of the instant invention, the center rotation of the club head is rotated adjacent the shaft which is at the center of the face rather than at one side thereof. Thus, a shot which is hit somewhat off center of the club will cause a lesser rotation of the club head than would otherwise be the case.
The club head of the present invention can be manufactured by conventional processes known in the art such 2 ~ 8 3 as investment casting. Any suitable material can be selected including material such as stainless steel and the like.
Similarly, conventional manufacture would include the provision of grooves along the face of the club head.
Having thus generally described the invention, reference will be made to the accompanying drawings illustrating an embodiment thereof, in which:

Figure 2 is a front elevational view of a golf club head according to the prior art;

Referring to the drawings in greater detail and by reference characters thereto, a conventional golf club 10 of the iron type is illustrated in Figures 2 and 4.
The conventional golf club head 10 includes a front face 12 and a rear face 14 with a bottom sole 16. Club 10 has a toe portion 18 and a heel portion 20 which merges with a hosel 22 to which the shaft of the club is attached. The front face 12 includes a plurality of grooves 24 as is conventional in the art.
As may be seen from Figure 2, adjacent the toe portion 18, the club head has a height "Y" while adjacent the heel portion 20 the club head has a height "y" wherein Y > y.
This is a substantially conventional arrangement utilized for most known golf club irons. Also, as shown in Figure 2, the club head has a width L which is the total overall width from toe 18 to heel portion 20; the effective hitting width is that indicated by reference character X.
Referring to Figures 1 and 3, a golf club head 30 according to the present invention is illustrated. Golf club head 30 includes a front face 32 and a rear face 34 and has a sole portion 36 extending along the bottom. Club head 30 also includes what is designated a toe portion 38 and a heel portion 40 with a hosel 42. Grooves 44 are provided on front face 32.
As may be seen from the drawings, hosel 42 is located intermediate toe and heel portions 38 and 40 respectively and the heights "Y" of both toe portion 38 and heel portion 40 are identical. All of the grooves 44 are of substantially uniform length and extend over the effective 2 ~ 8 3 hitting area of front face 32 with the distance "X" being equal to the distance "X" of the prior art clubs. Similarly, the overall width of the entire club face is substantially equivalent to that of a conventional golf club as shown in Figure 2.
Reference will now be made to the Figures 3 and 4 which illustrate the differences between the prior art and present club heads on a golf ball near the heel portion of the club head. Thus, as shown in Figures 4 and 6, when a golf ball 50 (shown in dotted lines) is struck close to the heel portion 20 of club head 10, not only does the ball 50 contact front face 12 at the point of impact designated by reference P, it can also contact the hosel portion at point 52. As shown by arrow 54, this will cause the ball 50 to move in a line off center to the intended direction. This can happen both if the ball is hit on the lower portion of the front face 12. When the ball 50 is hit at the upper portion (such as can occur with a wedge) the height "y" of the club head is not sufficient to provide full control over the ball.
As shown in Figure 3, since the front face 32 of club head 30 has a constant height "Y'~, and since the hosel portion 42 is located between the toe portion 38 and heel portion 40 and rearwardly of the front face 32, the point of impact P results in a ball making clean contact with the front face 32 and a better shot results.
Figure 3a illustrates a further club of the iron type but a "lower" iron such as 3 iron. As shown therein, the same results occur. As may be seen from Figures 3 and 2 ~ 8 '~
3a, the distance "G" between the hosel and club face 32 is slightly greater with the higher iron.
Figures 7 and 8 compare the impact of conventional head 10 and conventional 30 of the present invention when the ball is hit adjacent the toe portion. As shown in Figure 7, when the ball contacts club head 10 at point P, there is effective distance R from hosel or shaft portion causing the club head to open or rotate from the desired plane by an angle A. This results in the ball going off the intended court as indicated by arrows 58.
As shown in Figure 8, the same point of impact P on club head 30 of the present invention results in a distance _ from the point at which the club head will rotate and consequently, the angle the club head opens is reduced to _.
This results in the ball taking a direction indicated by arrows 60 which is half the error of that which would occur in the case of conventional club head 10 as shown in Figure 7.
It will be understood that the above described embodiment is for purposes of illustration only and that changes and modifications may be made thereto without departing from the spirit and scope of the invention.
