A golf club head is provided having a body and a face insert, with a slot in a perimeter region of the body of the club head adjacent the face insert. The slot increases the flex of the hitting surface on impact with a golf ball, thereby increasing the speed with which the ball rebounds off the hitting face and increases the overall distance the ball is hit. The slot preferably moves the sweet spot of the hitting face a distance X from the face center of the hitting face. The slot may be filled with an elastomeric material.

A golf club is fabricated with at least one vertical stability plate and / or at least one horizontal stability plate at a club head. The golf club is provided with a stability plate and an asymmetrical wing, or a combination of the same, which are installed at an upper side or left and right sides of the head of the golf club such as a driver, wood or iron, for example.An aerodynamic force generated in a downward direction by the loft of the club face is compensated by asymmetric wings applying an aerodynamic lifting force to an upper direction of the club head during a swing of the club. Even when a golfer has a swing speed or posture problem when swinging a club, the head of the club is guided to rotate along a desired proper orbit. A golf ball can be hit by a sweet spot of the head face of the club due to the stability and compensating force for achieving a straight drive, and enhanced flying distance.

A golf club head having an undercut is disclosed. The club head includes a body defining a striking face, a top line, a sole, a back, a heel, and a toe. The back contains a cavity that extends in a direction substantially perpendicular to the face. A recesses is provided within the cavity, with the recess extending away from the cavity and toward the sole. The recess causes more of the club head mass to be oriented towards the perimeter of the club head. This enlarges the club sweet spot and increases the moment of inertia, producing a more forgiving club. The recess may have a varying depth and / or a varying draft angle. A rear wall of the recess may be provided with a cutout to further reposition mass toward the club head perimeter. An insert, such as a vibration dampening member, may be provided within the recess. The insert may contain secondary inserts, such as weight members, therein in strategic locations. The insert may completely fill the recess, or may fill only a portion thereof.

A golf club head is provided having a substantially increased sweet spot. A preferred embodiment includes a striking plate, the striking plate having a striking surface, a rear surface opposed to the striking surface and defining a thickness therebetween, and a periphery. The periphery has a first edge, a second edge, a third edge, and a fourth edge. A balance point is disposed in a central region of the striking surface, a first thickness profile extending between the balance point and the first edge, a second thickness profile extending between the balance point and the second edge, a third thickness profile extending between the balance point and the third edge, and a fourth thickness profile extending between the balance point and the fourth edge. Each of the first, second, third, and fourth thickness profiles includes a first region encompassing the periphery of the striking plate, a second region disposed between the first region and the balance point, and a third region disposed between the second region and the balance point. Each of the third and fourth thickness profiles has a maximum second region thickness at least 1.5 times greater than a minimum first region thickness. Each of the first and second thickness profiles has a second region thickness that is less than the maximum second region thickness of the third and fourth thickness profiles and greater than or equal to the minimum first region thickness. Each of the first, second, third, and fourth thickness profiles has a third region thickness that is less than the maximum second region thickness of the third and fourth thickness profiles and greater than the minimum first region thickness.

A weight interchangeable golf putter is provided having a T shaped head. The head has a main body constituting the main weight and a striking face. From the trailing edge of the top surface a center tail extends rearward to form the T shape of putter plane. At the sides of the tail there are formed end fins with their free ends opened rearward to better guide the putter head through the air during the stroking address. The top of the back weight extends to near midway of the length of the tail and merges with the bottom of the tail. The back weight has a bottom surface in flush with the corresponding bottom of the main body and terminates with an end wall tapered gradually toward the main body to avoid hitting the ground when strokes are made. Three cylindrical bores are formed facing the same backward direction in the common 90-degree angle from the rear wall to receive different metal screws. When the screws are in their initial positions the putter with its face balanced neutralizes the leftward pulling or rightward pushing in the putting of the right-handed golfer who tends to show more pulling problems. Balance adjusting at the day's practice rounds or putting will be rightfully done with ease and no special tool thanks to the protruding screw design which provides an extra visual aid as well as a structural indicator of the invisible sweet spot to improve the actual approach of the ball into the hole cup.

An autostereoscopic multi-user display comprising a sweet-spot unit which is directionally controlled by a tracking and image control device (160), wherein an illumination matrix (120) is provided with separately activatable illuminating elements (11 . . . 56), in addition to an imaging device used to alternatingly image active illuminating elements, for making expanded sweet spots (SR1 / SR2) visible to various eye positions (EL1 / ER1, EL2 / ER2) of viewers observing alternating images or a stereoscopic image sequence on a transmissive image matrix (140) with the aid of directed beams (B1R . . . B5L). According to the invention, the imaging device comprises an imaging matrix (110) provided with a plurality of lens elements (111 115) whose focal length is small in order to image the active illuminating elements in an enlarged manner onto the sweet spots (SR1 / SR2), and a field lens (171), which follows the imaging matrix (110), in order to keep the distances of the activated illuminating elements between adjacent beams (B1, B2,B4, B5) as constant as possible and in order to assist selection of the directions (D1 . . .

Convenience and speed in switching applications on the touch screen terminals can be increased by the use of the method and device.

A golf club head having portions of varying density is disclosed and claimed. The club head includes a body with a recess in the back between the heel and toe and extending toward the sole. An insert that is configured to matingly correspond to the recess is positioned within the recess. The insert has a lower specific gravity than the club head body, biasing the club head mass toward the club head perimeter. The insert can form a muscle of the club head. The club head is forged, and the recess is formed by machining. After the insert is positioned within the recess, the club head-insert combination is subjected to additional forging and finishing steps. The present invention increases the club head moment of inertia and / or enlarges the club head sweet spot while retaining the golfer's ability to work the golf ball and shape the golf shot. The present invention can be used with forged, blade, and muscle back clubs, which have not heretofore been enhanced in these manners.

A golf putter head has a generally triangular shape where a ball-striking leading wall has a first breadth greater than a second breadth of a trailing wall. The leading wall and trailing wall are interconnected at their respective opposite ends by sidewalls that converge toward one another and define a cavity having a trapezoidal shape. The center of gravity of the golf putter head is closer to the trailing wall than the leading wall so that a moment of inertia is generated that reduces the effects of missing a sweet spot on the leading wall during a putt. In a second embodiment, the trailing wall is weighted to move the center of gravity still closer to the trailing wall. In a third embodiment, a web interconnects the leading and trailing walls along a longitudinal axis of the golf putter head, dividing the cavity into two equal-sized cavities.

A mallet-style golf ball putter with a hollow pipe component that has generally the same diameter as a golf ball, is positioned about the sweet spot in the vertical and lateral dimensions on the putter striking face, and extends longitudinally towards the rear of the putter to assist the golfer to align the striking face of the putter with the golf ball when in an address position and with the intended line of putt during takeback and follow-through. Peripheral weighting further enhances the moment of inertia of the golf putter head. The pipe component so designed permits a visual alignment of the striking face with the golf ball in the lateral and vertical dimensions and for a smooth perpendicular stroke along an axis of the pipe.
