Abstract: A self-aligning, low or no self-torque club that is both statically- and dynamically-balanced is provided which is less prone to deleterious effects during its approach to and while striking the ball Static balance is achieved by ensuing the shaft axis intersects the line between the geometric center of the club face and the center of gravity of the club head. The club is self-aligning because the center of gravity naturally follows the shaft and since the shaft and center of gravity are in-line with the face center, the possibility of striking the ball with the club face square increases. By providing a symmetrical and, preferably elliptical face, forces due to air resistance act equally on both sides of the face with respect to the shaft further aligning the club face with the swing path. To further alignment, the club head may also be provided with a series of convergent channels in the direction of air flow over the club.

Abstract: The present invention provides a wood-type club constituted such that the toe-down effect and the covering effects of the head can be more reliably suppressed. Attitude-correcting portions (30, 31) extending from the impact face (11) side to the back (14) side of the head are provided in at the least the toe (T) side and the heel (H) side of the head relative to a center line passing longitudinally through the head center of gravity in either the side parts (15, 16) or the sole (13) of the head (10), and are formed such that a portion of the highspeed airflow impacting the head at downswing is captured by at the least two attitude-correcting portions, either maintaining the head in a proper attitude, or correcting the head to a proper attitude.

Abstract: A golf club head 10 includes a crown portion 11, a face portion 12, a side portion 13 a back face portion 14, and a neck portion 15. The crown portion 11 has a protruded portion in which a maximum point P of a curved contour of a central cross section (X—X line) of the crown portion is positioned rearwardly of the center I of the golf club head, and a cut-away portion obtained by obliquely cutting off the rear peripheral portion thereof. A volume V2 of a back-face-portion-side portion of the golf club head, which is positioned rearwardly of the head center I, is greater than a volume V2 of a face-portion-side portion of the golf club head, which is positioned in front of the head center I.

Abstract: A low drag golf club head that provides greater club head speed, increased driving distance, and increased directional accuracy. An air inlet slot located on the front striking face of the golf club head channels air through an internal venturi shaped passage to an air outlet slot located in the wake region at the rear of the golf club head. Drag losses are minimized within the venturi shaped air passage and the air passage is additionally configured to provide a directionally oriented outlet air jet that operates to square the front striking face of the golf club head at and through impact, thereby reducing slices and hooks.

Abstract: A golf club shaft connects a grip of a golf club to a head of the golf club and has a longitudinal axis that extends from the grip of the golf club to the head of the golf club. At least a portion of the shaft has an aerodynamic cross-sectional shape defining an aerodynamic portion of the shaft. The aerodynamic portion of the shaft is oriented along at least a portion of the longitudinal axis of the shaft. The aerodynamic portion of the shaft is oriented relative to the grip and the head such that, compared to a gulf club shaft having a circular cross-sectional shape, the aerodynamic portion of the shaft is able to improve the stability of the shaft as the golf club is swung through the air in a particular with the head oriented to squarely strike a golf ball. The aerodynamic portion of the shaft may be integrally formed as part of the golf club shaft. Alternatively, the aerodynamic portion of the shaft may be by as a separate aerodynamic fin that may be attached to a conventional golf club shaft.

Abstract: A golf club with decreased air resistance in swinging to improve a head speed. A number of depressions 26 are formed on a back 4, a crown 6 and the side surfaces of a heel 7 and toe 8 of a head 1 of a wood club for example. Each depression 26 has a first side narrower than a second side thereof so that it is egg-shaped. The section of each depression 26 is formed smooth such that a slope at the first side is more gentle than that at the second side. Each depression 26 is desirably so oriented that its comparatively gentle slope is positioned at the face 3 side. Owing to these gentle slopes, the generation of a dead air region is suppressed at the inflow side of each depression 26, thus further decreasing an air resistance in swinging.

Abstract: A golf clubhead has been multi-angularly streamlined so that it presents reduced aerodynamic drag when swung throughout the entire 120 degrees prior to impact with a golf ball. During this portion of the swing, golfers typically rotate their golf club about the axis of its shaft by up to 135 degrees. During the 120 degrees of swing prior to ball impact, the club is typically accelerated from about 50 MPH to 100 MPH or more. The streamline shape is developed for higher efficiency for air flow encountered at the high speed portion of the swing arc at the expense of reduced streamline efficiency during the slower portion of the swing. The shapes herein conform to U.S.G.A. rules. Allowance is also made in the streamline shape for the non-radial sweep of the shaft during the earlier portion of the swing. In the preferred embodiment, a high strength faceplate is fitted to a low density aerodynamic fairing thereby creating a clubhead combination with a center-of-mass close to the plane of impact.

Abstract: The present invention consists of an improved wood head or driver design for a golf club in which the wood head or driver is preferably molded from a clear acrylic material or polymeric material or a high tech metal alloy wherein a plurality of elongated elliptical and/or V-shaped grooves or indentations extend normal to the club head striking surface and are embedded in the crown, toe and sole of the club head. These grooves initiate from just behind the striking face or leading edge, and extend rearwardly toward the back of the club wood head. The grooves create a corresponding plurality of vortices during the golf swing which redirect air flow rearwardly away from the back of the club head, reducing drag and the wind resistance of the moving club head, which in turn increases thrust and the overall distance a golf ball is capable of travelling during a given shot.

Abstract: A golf club having a hollow body clubhead with a metal mesh clubface and a metal mesh top-of-clubhead design. The design conforms to the shapes of a wood and iron and allows the club to be larger in size and weight than traditional golf club designs. The weight is controlled by modifying the amount of material forming the clubhead. The clubface hitting area for both the wood and iron is increased. The hollow-body allows air to flow through the clubhead, thus reduces air resistance and stabilizes the clubface during the club swing. The speed of the clubhead at impact increases, produces straighter flight of golf ball, and increase the distance the golf ball travels once hit. The design of the clubhead facilitates using a balance of different metals, by example, stainless steel, or other metal alloy. The design facilitates the force of the air to be directed against the inside bottom of the sole to provide better contact with a golf ball and reduce topped shots.
