Tip plate for a billiards cueTip plate for a billiards cue description/claimsThe Patent Description & Claims data below is from USPTO Patent Application 20090270192, Tip plate for a billiards cue. Brief Patent Description - Full Patent Description - Patent Application Claims
This application claims the benefit of U.S. Application No. 60/668,679, filed Apr. 6, 2005, the entire teachings of which are incorporated herein by reference. Cue sticks utilize a variety of materials in their construction. In particular, the tip of a cue stick, which is used to strike a ball during a billiards game, is typically made of a different type of material (e.g., leather or linen phenolic) than the actual shaft construction of the cue stick (e.g., wood). Therefore, the prior art has developed various methods for attaching the tip to the remainder of a cue stick In the prior art, the tip of cue stick is often attached to a shaft using a plug made of wood or plastic. Specifically, the shaft of the cue stick, at the distal end to which the tip is attached, has a cavity into which the plug is inserted. The tip is attached to the shaft by contact, through adhesive, with the tip end of the shaft and contact of the plug with the sides of the cavity. Repeated ball strikes by the tip over the life of the cue stick tend to weaken the bonding of the tip, resulting in eventual detachment of the tip from the remainder of the cue stick. This problem is especially prominent when the tip is directly bonded to a composite shaft surface because of the incompressibility of the composite material relative to the tip material. If a plug is not used, in the case where the tip is attached to the distal end of the shaft, the unequal loading of force on the tip causes especially high wear. Even linen phenolic tips exhibit substantial compressibility under the force necessary to strike a cue ball during a break shot. In addition, the plug tends to increase the weight of the cue stick near the tip end, accentuating a phenomenon known as cue ball deflection. When a player imparts english to a cue ball by striking the cue ball away from its center of mass, stick. As discussed in U.S. Pat. No. 6,162,128, the entire contents of which are hereby incorporated herein by reference, increased weight at the tip end of a shaft accentuates the deflection of a struck cue ball during off-center ball strikes. A need exists to provide a more robust way of attaching a tip to the remainder of a cue stick, while decreasing the weight of the tip end of the stick. Embodiments of the present invention are directed to addressing these needs. In an embodiment of the invention, a cue stick comprises a shaft having a cavity at a distal end; a high stiffness, lightweight tip plate attached to the distal end of the shaft; and a tip attached to the tip plate for striking a ball. The tip plate may be comprised of a lightweight material having a high stiffness, such as carbon fibers in a composite matrix or binder, Kevlar®, beryllium, titanium, boron, or magnesium. The tip plate may weigh less than about 0.4 grams and exhibit substantially no deflection under a force of less than about 1100 pounds. The shaft may comprise a composite material where the shaft directly attaches to the tip plate, or the shaft may be comprised of wood. The tip may be comprised of phenolic. The tip plate may be shaped as a disk or with an extending lip. Other embodiments of the invention are drawn to sections of cue sticks utilizing a tip plate and a method of striking a ball utilizing a cue stick having a tip plate to decrease ball deflection. The foregoing and other objects, features and advantages of the invention will be apparent from the following more particular description of preferred embodiments of the invention, as illustrated in the accompanying drawings in which like reference characters refer to the same parts throughout the different views. The drawings are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention. Continue reading about Tip plate for a billiards cue...
