摘要： A game racquet for tennis, racquetball, squash and the like, includes a handle having a free end and a racquet head defined by an open loop frame and having no weight heads. A throat connects the racquet head to the handle at an end of the handle opposite the free end thereof, with the open loop frame of the racquet head having a first half remote from the handle and a second half in closer proximity to the handle. A mid-section of the game racquet extends from, and includes, the second half of the open loop frame and the throat, to a point approximately 20 centimeters from the free end of the handle, with the weight of the mid-section of the game racquet being 25%, or less, of the total weight of the game racquet, when in an unstrung condition. In an alternative embodiment, the game racquet includes defining a portion of a closed loop frame of the racquet head. In this embodiment, the mid-section of the game racquet extends from, and includes, the second half of the closed loop frame and the throat, to a point approximately 21 centimeters from the free end of the handle, with the weight of the mid-section of the game racquet being 25%, or less, of the total weight of the game racquet, when in an unstrung condition.

摘要： A method for manufacturing an object having a potential {x} which is generated in response to a field {f} applied thereto is provided. The method includes the step of designing a geometric model of the object. A computerized mathematical model of the object is generated by discretizing the geometric model of the object into a plurality of finite elements and defining nodes at boundaries of the elements, wherein values of the field {f} and potential {x} are specified at the nodes. A material property matrix �k! is then calculated based on the relationship {q}=�k! {x}. Material property coefficients are then extracted from the material property matrix �k! for each finite element in the computerized mathematical model and the extracted material property coefficients are compared to material property coefficients for known materials to match the extracted material property coefficients to the material property coefficients for known materials. Manufacturing parameters corresponding to the matched material property coefficients are then determined. The object is then manufactured in accordance with the determined manufacturing parameters.

摘要： A game racket frame of metal material comprises a head frame, a handle, and a throat located between the handle and the head frame. The handle has a shaft portion which has one end that is coupled with the throat and another end extending axially and outwardly to form a hand grip. The hand grip is provided with an area adjacent to the shaft portion and having therein at least a slit of a width measured in a direction perpendicular to the longitudinal axis of the area. The width of the slit is at least corresponding to 3% of the circumferential length of any cross section of the area. The slit serves to interrupt and attenuate the shock wave that is generated by the head frame upon hitting a ball and is subsequently transmitted to the handle.

摘要： A method of making a game racket frame comprises the use of a tubular body of aluminum alloy consistent with a shape of a racket frame. An annular recess is provided respectively at the mid-point of the left-hand half of the head frame and at the mid-point of the right-hand half of the head frame. The annular recess is coated with adhesive resin. The tubular body is placed in a molding tool comprising a mold cavity having an annular ring which is located at a position corresponding to the annular recess of the tubular body and which has a shape corresponding to that of the annular recess of the tubular body and a size slightly larger than that of the annular recess of the tubular body. The molten plastic material is injected into the mold cavity under pressure and heat. Upon completion of the curing of the plastic material, the racket frame is removed from the molding tool. The racket frame so made is provided with weight-balancing pieces fastened securely to the head frame of the racket.

摘要： A frame structure adapted for use as a tennis racket. The frame structure includes a frame body made from either wood, metal or plastic having a tubular structure with inside and outside surfaces. A composite material jacket having an outer layer adjacent and bonded to the frame outside surface and an inner layer adjacent and bonded to the frame body inside surface is provided. The composite material jacket is made from composite materials such as resin impregnated boron, graphite, polyamide aromatic and glass fibers. In addition, plastic throat pieces commonly used to connect and support racket necks and handles are replaced by composite material cross-member supports which are integrally molded to the composite material jacket. The composite material jacket provides structural reinforcement as well as desirable shock and vibration dampening characteristics. In addition, the tubular frame is provided with elongated slots through which racket strings are attached for mounting. The composite material jacket when molded into place on the frame structure fills these slots with cured composite material thus providing a ribbed integral connection between the outer and inner jacket layers. Holes provided through these ribbed sections have cross-sectional areas smaller than the elongated slots thereby preventing undesirable contact of the racket strings passing therethrough with the metal frame structure.
