- the golf club 20 includes a head 22, a shaft 24, with a shaft axis 26 running therethrough, a grip 30, disposed on the shaft
- the hosel 32 includes a hosel top 34 and a hosel bottom 40.
- the hosel top 34 includes a socket 36 which is positioned to house the shaft 24 by conventional means.
- the hosel bottom 40 is connected to head 22.
- FIG. 2 depicts an embodiment of the golf club 20 that is an iron-type club.
- the head 22 includes a face 42 which includes a striking surface 44.
- the striking surface 44 is to be positioned perpendicular to a target line 46 when the club is at the address position prior to the swing.
- the striking surface 44 is preferably returned to a position approximately perpendicular to the target line 46 at impact, thereby causing a relatively straight ball flight.
- the striking surface 44 includes horizontal grooves 50 that impart backspin on the golf ball at impact.
- the head 22 further includes a toe 52 and a heel 54.
- the toe 52 is positioned at the end of the head 22 distal from the shaft 24 and
- the heel 54 is positioned proximal to the shaft 54 and connected to the hosel bottom 40.
- the striking surface 44 of the head 22 includes a leading edge 56 that is positioned at the
- the head 22 also includes a top 60 which includes a top edge 62 that defines the boundary between the top 60 and the face 42.
- the head 22 further includes a back 64 (not shown in FIG. 2) that is positioned opposite the face 42 and a sole 66 that is positioned opposite the top 60. The sole 66 rests on the ground when the club 20 is at address.
- the golf club 20 is shown in a position at address, prior to swinging of the club.
- the golf club 20 is superimposed on x-, y- and z-axes, reflecting three dimensions. Ideally, the club is returned to precisely the same position upon impact.
- the shaft 24 defines a projection 70 which is a plane running through the shaft that is perpendicular to the ground.
- the target line 46 T-T' runs from the striking surface 44 of the golf club 20 to the target.
- a face line 74 F-F' represents the line defined by the leading edge 56 of the face 42. Ideally, the face line 74 is perpendicular to the target line 46 at
- a face angle 76 is defined as the angle between the face line 74 and the target line 46.
- a face angle 76 that is greater than ninety degrees represents an "open" face 42.
- a face angle 76 of ninety degrees is desired at impact.
- a lie angle 80 is defined by the shaft 24 and the ground at the position where the projection 70 intersects the ground. The lie angle 80 is preferably in the range between 58
- the lie angle 80 is smaller than for a conventional inset hosel driver.
- FIG. 5 a side view of the hosel 32 of the present invention is shown.
- the hosel top 34 is positioned so that the socket 36 is inset by an inset distance 821-I' toward a center of gravity 23 of the head 22.
- the inset distance 821-I' is only the outside radius of the hosel top 34; that is, the edge of the shaft 24 is aligned with the heel of the club 20.
- the inset distance 821-F is greater than the radius of the shaft 24.
- the inset distance 821-I' is either progressive or constant, in the case of a progressive inset varying according to the loft of the club 20.
- the inset distance 82 I-F may be greatest in a driver, and may be progressively reduced as the loft of the club increases, so that each club, ranging from the one iron to the nine iron or wedge has a decreasing inset distance 821-F.
- the inset distance may be the same as for a conventional club in the shorter irons, beginning with the 7 or 8 iron.
- the progressive inset accounts for the fact that the tendency to slice is greater for the longer irons, the fairway woods and the driver, than it is for the short irons.
- the progressive inset permits the correction of the slice in the longer irons, driver and fairway woods, while it does not overcompensate for the tendency to slice the shorter irons.
- the progressive inset may be custom-designed to
- the inset may be kept constant for all clubs in a set.
- the hosel top 34 is positioned so that when the club 20 is at
- the hosel bottom 40 is hidden from the golfer by the hosel top 34; that is, a central axis 35 of the hosel top 34 is on the same plane as the center of the hosel bottom
- the plane is the equivalent to the projection 70 of the shaft 24, which is, in turn, perpendicular to the target line 46.
- the player will not compensate for the inset distance 82. Presence of an inset distance 82 reduces a moment arm 83 M-M' between the shaft axis 26 and the center of gravity 23 of the head, thus causing the head 22 to rotate more quickly in response to a given amount of force during the downswing.
- the hosel top 34 is positioned so that it is elevated relative to the hosel bottom 40.
- the tendency of the hosel 32 to impact grass, dirt, or other obstacles during the swing is reduced, allowing a smoother, more consistent impact, particularly in high rough or similar situations, than is the case with conventional golf clubs, on which the hosel typically touches the ground.
- the elevation of the hosel top 34 also decreases the tendency of the golfer to position the club in a "toe-down" position,
- FIG. 6 a top view of the hosel 32 of the present invention is provided. Again, the hosel top 34 is positioned so that the socket 36 is inset by an inset
- the vantage point of a golfer in the address position is provided, so that the hosel bottom 40 is not visible, being obscured by the shaft 24 and the hosel top 34.
- the club 20 has the appearance of a conventional golf club from this vantage point, despite the presence of an inset distance 82 I-F.
- the tendency of the golfer to overcompensate for a visible inset distance is eliminated.
- the distraction caused by a visible inset hosel is eliminated, permitting the golfer to concentrate on keeping the face 42 perpendicular to the target line T-T' 46.
- FIGs. 5 and 6 depict an iron embodiment of the present invention; however, a hidden inset hosel may be similarly provided for a fairway wood or driver embodiment of the invention.
- the hosel top 34 may also be positioned so that the leading edge of the hosel top 34 is offset by an offset distance 86 O-O' relative to the leading edge
- the offset distance 86 O-O' delays the point in time at which the golfer strikes the ball during the downswing, permitting the club to rotate further toward a square position at impact. A more square position at impact results in a reduced likelihood of a slice.
- the offset distance 86 O-O' is created by conventional means; however, the hosel top 34 is positioned so that the hosel bottom 40 is still hidden, notwithstanding the offset distance 86 0-0'.
- FIG. 7 depicts an iron embodiment of the
- offset distance 86 O-O' may be similarly provided for a fairway
- the head 22 of FIG. 7 is an iron-type head 90.
- the head 90 includes the toe 52, the heel 54, the top 60, the top edge 62, the back 64, and the sole 66.
- the iron-type head 90 is oversized relative to a conventional iron; in particular, the distance from the toe to the heel is preferably greater than 2.75 inches, and the height from sole to top is preferably greater than 1.75 inches.
- the iron-type head 90 is constructed with weight 92 on the back 64 of the head 90. In an embodiment of the golf club 20, the weight 92 is positioned about a perimeter 94 of the back 64.
- the perimeter weight 92 reduces the tendency of the head 90 to twist upon impact in cases in which the impact is off-center relative to the head 90.
- the weight 92 positioned on the perimeter 94 reduces the negative consequences of an off-center hit.
- the perimeter weight 92 also promotes a solid feeling at impact, promoting a smooth, confident swing.
- the weight 92 on the perimeter 94 of the back 64 is shaped in a widow's peak 96.
- the widow's peak 96 is positioned behind the center of the striking surface 44 (shown in FIG.
- the widow's peak 96 places additional weight behind the point of impact of the striking surface 44, tending to increase the distance of the shot when the ball is struck at or near the center of the striking surface 44.
- the widow's peak 96 compensates for some of the loss of power that can occur when much of the weight 92 is distributed away from the center of gravity 23 on the perimeter 94 of the head 22.
- the weight 92 on the perimeter 94 includes heel weight 100 and toe weight 102; that is, most of the weight 92 is distributed
- the top edge 62 of the face 42 is thick, relative to a typical top edge.
- the top edge 62 is of a thickness of at least .270 inches.
- the top edge 62 may be thinner, as in a conventional club. The thick top edge 62 increases the apparent size of the club, making it appear even more oversized than it is, instilling a high degree of confidence in the golfer
- the sole 66 includes a number of scallops 106.
- the scalloping of the sole 66 reduces the tendency of the club 20 to slow upon striking grass, sand, dirt or similar matter upon the downswing, by reducing the amount of material of the club that encounters such obstacles.
- the sole 66 includes a beveled leading edge 56. The beveling of the leading edge 56 increases the ability of the head 90 to cut through grass or other obstacles.
- the head 90 is oversized relative to a conventional golf club 20.
- the head may be constructed of conventional light, hard materials, such as stainless
- the shaft 24 may be any hard, relatively rigid material, such as steel or graphite, as used in conventional golf clubs.
- the head 90 may be manufactured by conventional manufacturing processes, such as investment casting or forging.
- the striking surface 44 of the face 42 has a pattern 43 that is circular.
- the pattern 43 assists the golfer in aligning the face 42 to a position where the center of gravity 23 of the head 22 is behind the ball, promoting a solid hit.
- FIG. 10 depicts a wood embodiment of the present invention, the pattern 43 may be provided in an iron embodiment as well.
- FIG. 11 depicts a driver, although embodiments such as fairway woods can be easily ascertained by one of ordinary skill in the art.
- a wood type head 116 is provided which is attached to the hosel 32.
- the head 116 is oversized.
- the head 116 is of a volume of two hundred seventy or more cubic centimeters.
- the oversized dimensions provide a large sweet spot and a large hitting surface to create a solid feeling shot and increased shot distance.
- the hosel top 34 is positioned so that the hosel bottom 40 is hidden to the golfer at address, as in the iron embodiment of the invention.
- the inset distance 82 I-F is similar to that in the iron embodiment of FIG. 5, and it offers it similar advantages in maneuverability.
- the wood embodiment includes a marking 120 that is
- the marking 120 resembles a bird's eye; that is, the marking 120 includes a point 122 that is above the center of the striking surface 44 substantially in a line between the center of the striking
- the marking also includes a semi-circular line 123 extending in a semi-circle about the central point.
- the marking 120 enables the golfer to position the striking surface 44 in a position that is centered relative to the ball at address, increasing the likelihood that the face will strike the ball in a position close to the center of the striking surface 44.
- the head 116 is constructed of a hard material such as Titanium; however, only the top 60, back 64, and sole 66 of the head 116 are painted, leaving the face 42 unpainted. In addition a small portion 61 of the top 60 is left unpainted in a positioned proximal to the top edge 62 of the face 42.
- the painting defines a paint line 130.
- the painting of the head 116 in this manner creates a simulated face plate 126, similar to titanium face plates that are added to conventional golf clubs for additional power.
- the painting creates a psychological impression on the golfer of increased power, without the added weight or expense of a
- the paint line 130 is positioned so that it is open relative to the target line 46 T-T' prime when the face line 74 F-F' is perpendicular to the target line 46. Because the
- paint line 130 appears to be parallel to the face line 74, the golfer is encouraged to position the paint line 130 perpendicular to the target line 46 at address.
- the face line 74 F-F' prime forms an angle of slightly less than ninety degrees to the target line.
- the face line 74 F-F' forms an angle of eighty-eight degrees with the target line 46.
- the closed face 42 at address compensates for the tendency of the high-handicap or amateur golfer to bring the club face 42 to an open position at impact; thus, the paint line 130
- the combination of the open-faced paint line 130 and the increased maneuverability due to the inset 82 means that the golfer is likely to bring the club to a position that is square at impact, substantially reducing the chance of a slice.
- a driver with a very low degree of loft is provided, in which the paint line 130 is parallel to the leading edge 56 of the face 42, or in which the paint line 130 is closed relative to the target line T-T' 46.
- the hosel top 34 is positioned so that it is elevated relative to the hosel bottom 40.
- the tendency of the hosel 32 to impact grass, dirt, or other obstacles during the swing is reduced, allowing a smoother, more consistent impact, particularly in high rough or similar
- the elevation of the hosel top 34 also decreases the tendency of the golfer to position the club in a "toe-down" position, thereby causing a corresponding decrease in
- the center of gravity 23 of the head 22 may be offset
- the head 116 may be manufactured by conventional manufacturing processes, such as investment casting or forging.
- the head 116 may be constructed of any light, hard material, such as 6-4 Titanium.
- the face 42 may be constructed of a different material that the rest of the head 116.
- the head 116 and shaft 24 may be attached to the hosel 32 by conventional means.
- the sole 66 of the head 116 of the wood embodiment of the golf club 20 is constructed so that the center portion 67 of the sole 66 projects a greater distance from the top edge 62 than do a toe portion 69 and a heel portion 71 of the sole 66. As a result, the amount of the head 116 that strikes grass, dirt, or other obstacles during the swing is reduced, allowing a fuller, more consistent impact with the ball.
