Abstract: Disclosed is a putter assembly. When fully assembled, the putter allows an individual using said putter (the “player”) to strike a golf ball with either one of the three available striking surfaces. Said choice of striking surfaces allows the player to utilize the front load putting method, and in alternative, the left or the right handed side putting method. The putter assembly comprises of three primary components: 1) U-shaped striking plate, incorporating the left, right and the front striking plate, wherein each of said striking plates further comprises of an impact area; 2) the frame, comprising of the back connecting member, with a disc for stacking weight plates, and the front connecting member, with a hosel for attaching thereto a shaft; 3) and the shaft, allowing the player to manipulate the movement of the putter. The assembly also incorporates putter alignment features, designed to help the player improve his/her shot accuracy.
Abstract: Multi-layered golf balls having a core, intermediate layer, and cover are provided. The ball includes a non-foamed inner core (center) made of a thermoplastic or thermoset composition such as polybutadiene rubber. An intermediate layer comprising a foamed composition, such as polyurethane foam, is disposed about the inner core. The foamed intermediate layer may have a specific gravity gradient within the layer, wherein the outer surface specific gravity is greater than the midpoint specific gravity. Ball constructions having two intermediate layers, wherein at least one layer is a foamed layer can be made. A cover having at least one layer is disposed about the intermediate layer.

Abstract: The invention provides a golf ball having a core and a cover of one layer or a plurality of layers, wherein the core is formed of a material molded under heat from a rubber composition containing (A) a base rubber, (B) an organic peroxide, and (C) water and/or a metal monocarboxylate, and has a hysteresis loss of 50% or less when compressed at a load cell speed of 500 mm/min and under a constant load of 5,000 N.
Abstract: Disclosed herein are some embodiments of a golf club head with a tapered sole weight. One embodiment comprises a golf club head comprising a sole weight; and a body comprising a sole comprising an exterior sole surface, wherein a sole weight port is formed in the sole. The sole weight port can have a port top comprising an interior port top surface and an exterior port top surface, wherein the interior port top surface has a taper of plus or minus approximately 1-89 degrees with respect to the exterior port top surface. The sole weight port can comprise a weight-receiving cavity that engages the sole weight. Other embodiments for related club heads and methods are also disclosed.
Abstract: A golf club head with a hollow therein includes a head main body and a crown member. The head main body includes a face portion having a hitting face, a crown portion provided with an opening and a peripheral region forming around the opening, wherein the opening is covered with the crown member. The peripheral region of the opening includes a mounting portion for mounting the crown member with an interior surface and an exterior surface thereof. The mounting portion, at least, includes a face-side mounting portion, a toe-side mounting portion and a heel-side mounting portion. The crown member includes a face-side peripheral portion fixed to the interior surface of the face-side mounting portion, a toe-side peripheral portion fixed to the exterior surface of the toe-side mounting portion and a heel-side peripheral portion fixed to the exterior surface of the heel-side mounting portion.
Abstract: A golf club head has a body defining a ball striking face. The body further has a first leg extending away from the ball striking face and a second leg extending away from the ball striking face wherein a void is defined between the first leg and the second leg. The body further defines a cover that extends over the void. The golf club head may further have support structures and adjustable weight members.
Abstract: A putter having a body with a striking surface, an upper surface that is visible to a player when in the address position and a sole plate that is coupled to a bottom surface of the body. The upper surface includes at least one aperture and the sole plate includes a sightline projection that extends into the aperture to form a sightline on the putter that is visible to the player.
Abstract: Provided are a golf club head and a golf club with a plate member that is resistant to peeling and has a glossy appearance. A golf club head includes a face portion including a ball striking surface, and a plate member connected to a back surface located on the back side of the face portion. The plate member includes a resin and a metal material. The metal material is arranged on at least any one of a toe side and a heel side of the face portion and is arranged so as not to planarly overlap a striking point of the face portion.
Abstract: Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion with a toe portion, a heel portion, a rear portion, a front portion with a strike face, a sole portion, and a top portion with a plurality of ports. The body portion may define a periphery of the golf club head. The golf club head may also include a plurality of weight portions with each weight portion disposed in one port of the plurality of ports. Other examples and embodiments may be described and claimed.
Abstract: A golf ball comprising a core comprising an inner core center and an outer core layer disposed over the inner core center. The inner core center has a deflection of greater than 0.210 inch under a load of 100 kilograms, and the entire the core has a deflection ranging from 0.130 inch to 0.105 inch under a load of 100 kilograms. A mantle layer is disposed over the core and a cover is disposed over the mantle.
Abstract: A golf club 2 includes a head 4, a shaft 6, and a grip 8. The club 2 has a forward club flex of greater than or equal to 140 mm. The forward club flex is measured for a golf club in the completed state. The grip 8 has a weight Wg of less than or equal to 30 g. With the golf club 2, a force acting on the player's body during a swing can be reduced. The golf club 2 can stabilize swing.
Abstract: A golf club head comprising a slidable weight for adjusting the location of the club head center of gravity is disclosed herein. The club head has a channel disposed in its sole and a slidable weight assembly comprising a weight body and a rotatable cam portion. The channel includes a single, L-shaped rail extending upwards from a channel floor, and the slidable weight assembly is reversibly fixed to the rail when the rotatable cam portion is rotated such that a curved protrusion is disposed underneath a ledge of the L-shaped rail. The channel preferably has an S-shaped or closed loop configuration such that the club head's center of gravity can be adjusted along X (front to back) and Y (heel to toe) horizontal axes.
Abstract: Multi-piece golf balls containing a dual-layered core are provided. The ball further includes single or multi-layered covers. The core structure includes a small, heavy inner core (center) having a relatively high specific gravity, and a surrounding outer core layer. The core layers may have different hardness gradients. The center of the core comprises a metal material such as copper, steel, brass, tungsten, titanium, aluminum, and combinations and alloys thereof preferably dispersed in a thermoplastic polymeric matrix. The outer core layer is preferably formed from a thermoset composition such as polybutadiene. These multi-layered core constructions with metal-containing centers have selective specific gravity relationships between the different layers. This helps provide the ball with good flight distance and spin control. The resulting balls have good resiliency and other playing performance properties.
