Abstract: An apparatus allows a golfer to improve his or her swing. A striking pin is mounted on a club head using a rigid bracket. The golfer swings so as to strike a golf ball with an end surface of the striking pin. Progressively smaller striking pin end surface areas may be used. After practicing using the striking pin, a golfer removes the striking pin and continues with normal play.

Abstract: A golf club which comprises a shaft and an improved club head, the club head having a toe portion, a heel portion, a sole, a front face defined by a bottom edge adjacent the sole, a heel side edge and a toe side edge adjacent the heel and toe portions respectively, and a top edge, the front face having a recessed portion extending substantially between the heel side edge and the toe side edge. The recessed portion may have various configurations from concave to the combination of different planar surfaces.

Abstract: A golf putter having a removable ball striking insert received in a recess formed in the front surface of a putter body. Ball striking inserts having various weight, texture and hardness characteristics may be interchanged with the putter body in order to provide different putting characteristics to the golf club.

Abstract: A golf putter including a head having a face, a shaft and a grip. The face comprises a centered first face, a second face formed on one side of the first face and inclined inwardly, and a third face formed on the other side of the first face and inclined inwardly. A plurality of friction protrusions are formed on the surface of the first face for improving the contact resistance. A plurality of spin protrusions are formed in the shape of steps on the surface of the second and third faces, respectively, so that a golf ball collided therewith rotates inwardly. Therefore, under any topographical condition, that is, a relatively flat green or an inclined green, the golfer can putt the ball directly into the hole without having to consider the curvature of the golf ball to the right or left side, thereby improving the accuracy of the putting operation.

Abstract: The putter head of the invention defines a ball striking face which is composed of a plurality spaced heads having ball engaging faces and a hosel with a plurality of fingers, each finger of which is integrally attached to a respective head section.

Abstract: A golf putter includes a putter head that is equipped with three ball-striking surfaces, such that the putter can be used by a right-handed golfer or a left-handed golfer, employing either a conventional putting stance perpendicular to the ball roll path or a non-conventional putting stance facing the ball target. The club head is connected to the shaft at a center location coinciding with the head center of gravity. Also, the upper surface of the putter has a central cavity and two opposing rails that cause the putter weight to be concentrated at the perimeter of the head, thus tending to minimize the effect of mishits on ball travel accuracy on all three ball striking positions. The shaft to head connection is aligned with the ball roll in all ball striking positions.

Abstract: A golf club of the type for putting and driving a golf ball. The golf club has a reflective surface which is positionable to direct toward a golfer's eye an alignment image including an image of the ball and the target into which the ball is directed so as to aid the golfer in positioning the head of the golf club relative to the ball. The reflective surface is removable from the head so as to be stowed when not in use. The golf club also includes a leveling device in the head of the club to indicate to the golfer when the head is aligned horizontally. The golf club further includes a first striking surface with a tilted striking surface portion for imparting spin to the golf ball, and a second striking surface opposite the first for directing the ball in an upward trajectory. The tilted striking surface may include a flat central portion and an adjacent flat end portion, both of which contact the golf ball.

Abstract: A playground golf course with an artificial turf, the greens of which are formed by disposing a thin resilient urethane foam layer below the artificial turf so as to reduce golf ball bounce and hence roll on the artificial turf. Greens are formed by disposing a polyethylene buffer below the thin layer and disposing a green boundary edge member composed of an artificial turf belt member around the artificial turf. Greens are also formed by tensioning predetermined portions in the vicinity of the periphery of the artificial turf with springs. The playground golf course is formed by disposing a plurality of greens formed in such a manner in an existing athletic facility. The playground golf course is composed of the greens, a golf club with two club heads formed at both ends of a shaft, a golf ball with reduced flight characteristics, and a golf tee that allows players to easily hit golf balls.

Abstract: A golf putter includes a handle having a lower end to which a head is fixed. The head has a left side face and a right side face. The left and right side faces are symmetrical to each other and may both be used to putt a golf ball. The head further has a front face which may also be used to putt the golf ball as the player stands facing the target hole and spaces his or her legs on both sides of the ball. The putter is then swung under the crotch and between the legs of the player as a pendulum to putt the ball with the front face thereof which is substantially normal to the horizontal as it gets into contact with the ball. The handle of the putter is shortened as compared to the conventional putter to facilitate the swinging operation.

Abstract: A golf putter has an elongated shaft, a neck, and a club head. The neck extends between the shaft and the club head. The club head has a striking face and a rear wall opposite the striking face, a top surface and a sole surface opposite the top surface. The top surface of the club head is oversized and in shape of a parallelogram. The breadth of the club head being at least 3.0 inches, preferably between 3.0 and 4.5 inches. The longitudinal axis of the shaft and the striking face of the club head is coplanar. In a preferred embodiment the shaft longitudinal axis is sub-perpendicular to the longitudinal axis of the striking face of the club head. In one embodiment the sole surface of the club head is sloped. In a preferred embodiment the sole surface has two cavities separated by a strut extending from the striking face of the club head to the rear wall.

Abstract: A matched pair of golf clubs, designed for putting and chipping usage, which have identical heads with identical shafts and grips except that one head has a striking face with the loft of a putter and the other head has a striking face with the loft of a chipper, the said clubs being otherwise identical in weight, length, balance and feel. Preferably each head has a striking face with the loft of a putter and a reverse striking face with the loft of a chipper, with one club being a right handed putter and a left handed chipper and the other club being right handed chipper and a left handed putter. Chipping and putting with these clubs, using the clubs in sequence and in the manner of a putter, tends to improve the golfer's confidence and the chances of finishing a hole with fewer strokes than might otherwise be the case.

Abstract: A golf club has a triangular prismatic head. The top and bottom faces of the club head are parallel and of isosceles triangular shape. The shaft is aligned with the center of mass of the club head. The improved balance and visual cues given by the triangular prismatic shape improve the club positioning and stroke.

Abstract: A golf club head includes a body having a central plane, and a front planar face for striking a golf ball. The front planar face is at a negative angle in the range of 4.degree. to 8.degree. to the central plane so that a bottom edge of the front planar face is closer to the central plane than is a top edge of the front planar face. The center of gravity of the head is substantially aligned with the point on the front planar face which is the point of impact of a golf ball. The golf club head further includes attachment means for attaching a shaft to a top portion of the body parallel to the central plane.

Abstract: A two-faced golf club for right-handed or left-handed golfers having a vertical shaft and putter blade with a top surface, a bottom surface, a putting face, a chipping face, and a front surface. The top surface and the putting face meet at an angle of about ninety degrees and the top surface and the chipping face meet at an angle of at least one hundred and thirty degrees relative to the vertical shaft. The vertical shaft meets the blade at a center point on the top surface of the putter blade allowing versatility for both right-handed and left-handed golfers. The bottom surfaces of the golf club are preferably rounded to prevent "stubbing" with the ground during play.

Abstract: A golf ball flight angle demonstration device includes a rigid body including integral first and second simulated golf club heads with bottom sole surfaces extending between heel and toe ends. A first club face is located on the first simulated golf club head on a plane set at a first loft angle. A second club face is provided on the second simulated golf club head on a plane set at a second loft angle that is greater than the first loft angle. The club faces are oriented in relation to one another such that the planes of the first and second faces intersect along a reference line substantially parallel to a line tangent either of the sole surfaces at a reference face centerline extending through either club face.

Abstract: An adjustable head golf club has a selection ring (16) positioned with shank end ratchet teeth (19) in ratchet relationship to shank ratchet teeth (20) and with head end ratchet teeth (17) in ratchet relationship to head ratchet teeth (18). A fastener rod (4,10) is extended intermediate a club attachment base (11) on the back side (29) of the club head (1) and a shank attachment base (12) on a shank (2). A fastener head (44, 45, 46) of the fastener rod can be buttressed either against an inward side of the club attachment base or against an outward side of a shank attachment base, depending on design preferences. A plurality of shank end ratchet teeth and shank ratchet teeth is different from a plurality of head end ratchet teeth and head ratchet teeth.
