Abstract: A golf training system whereby a user can accurately determine a plurality of swing defect types that he or she may have committed while playing the sport of golf. Moreover, the user will be able to determine many of the more common swing defect types with each stroke. An indicia creating mechanism is mounted within the swing path of the clubface of a golf club. During the swing, the indicia creating mechanism will deposit an ink mark or indicia on the clubface of the golf club. This mark will be characteristic of the type, if any, of swing defect committed. Following the swing, the user will be able to observe the indicia pattern created on the clubface and then having been made aware of any specific swing defect which may have been committed, make corrections can be made on the next swing attempt.

Abstract: A convex, hemispherically shaped striking member is removably attached to the blade of a putter. Practice putting strokes are executed. The trajectory of the golf ball indicates whether the golf ball was struck squarely. Repeated practice, resulting in putting strokes in which the ball moves in a straight line in the intended direction, builds muscle memory for executing a desired putting stroke and improved concentration and focus on the golf ball.

Abstract: The purpose of this invention is to provide a golf putter with which players are capable of making accurate putts.

Abstract: A U-shaped alignment attachment is mounted on a putter and includes laterally inwardly spaced apart parallel leg extensions which have rearward ends spaced sufficiently from the golf ball when being addressed that they will engage the golf ball when the club is moved rearwardly on the backstroke if the club is off the intended line and engage the forward ends of the leg extensions on the forward stroke giving immediate feedback to the golfer as a result of the golf ball going off in an exaggerated mishit direction. Appropriate jaws are provided for mounting the attachment on different types of golf clubs.

Abstract: A golf putting practice apparatus for improving one's stroke and accuracy in putting a golf ball with a putter, comprising: two cord positioning and holding members, each member having an inner face portion, and adapted to hold portions of the length of cord in spaced parallel linear alignment between the members; and, a length of cord extending between the two inner face portions of the cord holding and positioning members. The golf ball may be initially positioned and subsequently putted between the parallel portions of the cord; thereby enabling one to better judge the linearity of the stroke of the putter and the accuracy of the putt by reference to the portions of the cord held in parallel and spaced alignment on each side of the ball. A method of using the above apparatus is disclosed which includes the step of applying two strips of colored tape to top portions of the putter in a position which vertically corresponds to the position of the cord therebelow.

Abstract: At least one, and preferably a pair, of golf ball markers with magnets incorporated therein are employed in combination with a golf putter as a putting training aid. The golf ball markers may be placed a short distance apart on the ball-impact impact face of the putter for a golfer to practice putting. If the golfer correctly brings the putter face into contact with the ball, the ball will be impacted by the center of the face directly between the two magnetized ball markers. If the golfer's putting stroke is not correct, one or the other of the ball markers will strike the ball, thereby creating a tactile sensation transmitted through the putter shaft that informs the golfer of the error in execution of the putting stroke. Magnetic golf ball markers may also be used in combination with a putter in other ways to develop a putting stroke that is consistently correct. The golfer places two of the golf ball markers with magnets incorporated therein on a golf putting practice surface.

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 putter head includes a main body with a front face upon which is carried a resilient ball-striking pad. The pad comprises a fibrous material having a resiliency so that impact forces when the head strikes a ball are elastically absorbed while imparting an optimum kinetic feel to the user. The fibrous material also produces an optimum reaction force against the ball for propelling it outwardly from the putter head. Certain embodiments provide for recessing the pad in the face of the head for providing a backing layer between the pad and recess, and for releasably attaching the pad to the face.

Abstract: A golf club head with striking surface density control having a club head having a mounting face defining a surface or recess for interchangeably receiving and accepting a selected one of a plurality of pads or inserts, each of which is composed of material having a different density. The mounting face detachably anchors or holds the selected pad or insert in place by screws, clips, adhesive or the like. Guides are provided on the club head for aligning the pad or insert with the mounting face. In one form, the pad or insert may be insertably received within the recess and anchored by fastening or alternately, adhesive may be employed to releasably secure the pad to a flat club surface.

Abstract: A training device for developing a golfers swing based on a principle of driving a spike fixed to the sweet spot of a striking surface of a golf club, into the flat target surface of a slab of material selected to permit penetration and fixation of the spike in the target surface. The slab is preferably styrofoam and is supported by a stake inserted through the slab and into the ground. In an alternative arrangement, the slab is temporarily supported in its erect position by inserting its lower end in a slot in a pad.

Abstract: A ball-impact-error sensor/amplifier is bonded to the ball hitting point of a golf club face and includes an adhesive backed base in the form of a soft plastic disc, 1/2 inch diameter.times.3/16 inch thick, with a center hole that holds a flat-ended, rigid probe 1/8 inch diameter.times.1/4 inch long, seated upright on the club face so that for the forward swinging club to strike the ball solidly, the club face, probe and ball must compress together squarely at impact, failing which, the probe and wall of the probe base will spring-hinge aside under impact, thereby strongly amplifying impact errors into jarring and blatant mis-hits that must be curbed for ball striking mastery.

Abstract: A golf practice aid which uses a pressure-sensitive double-sided tape for removably attaching the aid to the club face of prior art club without noticeably changing the characteristics of the club. The practice aid preferably includes a metal base, which at its center has a circular ball striking platform which is raised from the base by means of a beveled edge and, at each end thereof, a raised, linear, triangular, alignment rail. When properly stroked with the club, the ball hits on the circular striking platform thereby causing the golf ball to go in a straight line in the direction of the target. When the golf ball is improperly stroked it strikes on the beveled edge surface and is turned away from the target.

Abstract: A new golf swing training device for providing a visual frame of reference for correctly completing the swing of a golf club having the training device installed thereon.
