SHEET 2 OF 2 WEDGE TYPE GOLF CLUB BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to a wedgetype golf club and more particularly a sole incorporated into the undersurface of a golf club head to facilitate Iofting of the golf ball with the sole including a slotlike opening extending from the leading edge of the club head to provide for passage of sand thereby effectively reducing the quantity of sand that engages the club face to enable direct contact of the golf ball with the club face for more accurate control of the golf ball when it is pitched" onto the green from a sand trap. The sole also provides for more effective lofting of the golf ball from the fairway to the green since the sole comes into contact with the turf of the fairway and will reduce the quantity of turn engaging the face of the club.

2. Description of the Prior Art Most golfers employ a wedge-type club for use in driving a golf ball out of a sand trap or from the fairway onto the green. The angle of inclination of the club face is such that the ball will be lofted in a relatively high trajectory with sufficient accuracy and spin to position the ball as close as possible to the hole. In using conventional wedge-type clubs, considerable grass, turf and the like will be engaged with the face of the club and between the face of the club and the golf ball which reduces control of the golf ball when the golf ball is on the fairway adjacent to the putting green. When in a sand trap, a substantial quantity of sand engages the club face and is disposed between the golf ball and club face so that substantial accuracy is lost when the ball is blasted out" of the sand trap. Thus, while conventional wedge type clubs perform satisfactorily under some conditions and when used by skilled golfers, there is a substantial need for improvement in wedge-type golf clubs to enable more consistent accuracy and control of the golf ball when it is pitched onto the putting green from either a sand trap or adjacent area of the fairway.

SUMMARY OF THE INVENTION An object of the present invention is to provide a wedge-type golf club having a conventional angle of inclination on the club face and also a conventional club face to enable the club to meet regulations of the various golf regulating agencies which have set up requirements for the various types of clubs permitted in sanctioned golf matches or tournaments together with an added sole underlying the undersurface of the golf club head to provide a supporting surface for the golf club head when it engages a sand or fairway surface. The sole is spaced from the undersurface of the golf club head and attached thereto only at the ends thereby providing a slot-like opening to enable sand or other supporting material for the golf ball to pass through the slot-like opening as the golf club head approaches and engages the golf ball thereby reducing the quantity of sand or other supporting material for the golf ball which comes into engagement with the face of the golf club head thereby increasing the control and accuracy of the flight path of the golf ball thus enabling the golf ball to be more accurately driven to a desired area of the putting green adjacent the hole.

Another object of the invention is to provide a wedge-type golf club head of unitary construction in which a curved and relatively wide sole is mounted below the undersurface of the golf club head at the heel and toe portion thereof and in spaced relation to the undersurface with the spaced relationship providing a slot-like passage beginning immediately rearwardly of the leading edge of the club head and extending towards the trailing edge thereof with the leading edges of the sole and the mounting structures therefor being rounded and tapered in a manner to reduce obstruction to passage of sand and the like through the slot-like passage.

Still another object of the invention is to provide a wedge-type golf club head having a slot-like passage incorporated into a sole thereon which is effective in controlling the flight of a golf ball when driven from a sand trap or fairway area adjacent the putting green with the club head being relatively simple in construction and effective in use by golfers having different degrees of skill.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front elevational view of the golf club head of the present invention.

FIG. 2 is a vertical sectional view of the golf club head as taken along section line 2-2 of FIG. 1.

FIG. 3 is a rear elevational view of the golf club head.

FIG. 4 is an end view of the golf club head.

FIG. 5 is a bottom plan view of the golf club head.

FIG. 6 is a top plan view of the golf club head.

FIG. 7 is a sectional view similar to FIG. 2 but illustrating the club head moving through sand.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now specifically to the drawings, the golf club head of the present invention is generally designated by the numeral 10 and includes the usual upwardly extending shank 12 in a well known angular position to which is attached the elongated golf club shaft 14 having the usual handgrip at the upper end thereof. The golfclub 10 is of the wedge-type and includes a relatively thin body 16 extending from a lower leading edge 18 to an upper trailing edge 20. The upper face or club face 22 is substantially flat and provided with longitudinal grooves 24 thereon for effective contact with a golf ball 25 in a well known manner. The angle of inclination of the face 22 is conventional for a sand wedge or pitching wedge with the shank 12 being connected integrally at one end thereof by a connecting area 26 with the leading edge 18 being substantially straight but slightly rounded and the trailing edge 20 being curved in a more exaggerated manner with the outer end portion of the club head being wider than the inner end portion and the outer end edge of the club head being rounded as at 28. As stated previously, the shape and configuration of the club head face 22 is conventional as is the angle of inclination thereof and positioning and angulation of the shank 12 so that the club head will meet all requirements of the regulatory agencies regarding golf.

As illustrated in FIG. 2, the undersurface of the golf club head body 16 generally parallels the face 22 thereof with the area adjacent to but spaced rearwardly from the leading edge being slightly thickened as at 30. Positioned in underlying spaced relation to the undersurface of the club head body 16 is a sole 32 which, as illustrated in FIG. 5, generally underlies the central portion of the club head and has a plan shape somewhat similar to the plan shape of the club head although it is shorter than and narrower than the club head. The sole 32 includes a leading edge 34 generally parallel to, spaced rearwardly from and spaced downwardly from the leading edge 18 although when the club head is swung, the leading edge 34 of the sole 32 is generally in horizontal alignment with the leading edge 18 at the position of the club head when it strikes the ball. The sole 32 also includes a trailing edge 36 which is spaced forwardly from and spaced further below the trailing edge 20 as illustrated in FIG. 2. The trailing edge 36 is rounded or curved generally in the same curvature as the trailing edge 20 and the two end edges of the sole 32 are rounded and are supported in depending relation to the undersurface of the club head body 16 by supporting

webs

38 and 40 which are disposed adjacent to the end edges of the sole but spaced slightly inwardly from the end edges thereof. The upper and lower surfaces of the sole 32 are generally parallel with the upper surface being substantially flat and the lower surface being curved with the leading edge 34 being thinner than the trailing edge 36 so that the lower surface of the sole will engage the sand surface or turf surface for supporting the golf club head from such surface.

The

webs

38 and 40 combined with the upper surface of the sole 32 and the undersurface of the club head body define a slot-like opening or passageway 42 which commences just rearwardly of the leading edge 18 and extends to the trailing edge 36 of the sole 32 which provides for unrestricted passage of sand, turf or the like which supports the golf ball so that a lesser amount of such material will engage the club face (seeFlG. 7). Thus, the golf club head will loft a ball out of the sand with the sole serving to support the golf club head and to reduce the sand engaging the face of the club which would normally prevent proper contact of the ball to the face of the club. Therefore, with this club, the average sand shot will become a relatively easy pitch shot rather than a sand blast which frequently is inaccurate and results in an undesirable positioning of the golf ball after the shot. The slot-like opening or passageway allows the sand to pass through the sole and under the face of the club with a minimum of sand on the club face. Also, when the club is used on the fairway, the sole contacts the turf and provides a support for the club head rather than permitting the club head to cut into the turf which materially interferes with the accuracy of the shot. Thus, a golfer even of average skill will be able to more accurately drive the golf ball from a sand trap or the fairway onto the putting green thereby enabling him to reduce the shots necessary to complete a round of golf so that he will receive more benefit and enjoyment therefrom.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
