Abstract: A dimpled configuration for a golf ball wherein, in the first embodiment, the dimples are arranged in a geometrical lattice configuration so as to form a perfect icosahedral pattern which inlcudes twenty indentical triangles with a predetermined number of dimples lying along the lines forming the lattice. These dimples are a first diameter, while the dimples within the lattices are of a second diameter greater than the first diameter. In the second embodiment, the five adjacent triangles having common polar vertices are retained on either side of the equatorial line of the ball. Five smaller triangles on either side of the equator include vertices common with each adjacent set of the five triangles, with the legs opposite such vertices being substantially parallel with but terminating short of the equatorial line of the ball. The legs parallel with the equator extend about the ball so as to form five trapezoids which have common sides with the alternate with the five small triangles.

Abstract: Golf balls exhibiting an improved coefficient of restitution are obtained by the inclusion of dialkyl tin difatty acids in the core formulation.

Abstract: A softball having a core and a cover wherein the ball has a circumference of approximately 12 inches, a weight of 175 to 178 grams, a coefficient of restitution of approximately 0.478 and a compression from about 0.010 to 0.014 inches, wherein said core has a density from about 15.5 to 16.5 pounds per cubic foot, and a hardness from about 72 to 78 on the shore A scale, said core being formed from a cellular polymeric material. The core is surrounded by a cover having a specific gravity of about 1.2, a thickness from about 0.035 inches to 0.060 inches and a hardness from about 78 to 90 on the Shore A scale. The cover is formed from a vinyl resin, a phthalate compound, stabilizers and a titanium dioxide dispersion.

Abstract: Golf balls exhibiting superior durability and improved coefficient of restitution is provided by the inclusion of a dispersing agent in the core formulation.

Abstract: An improved child safety seat coupleable to the seat of a car through a three-point safety belt with restraining means to hold a chil therein. The safety seat has a U-shaped tube with an upper horizontal leg and spaced downwardly extending vertical legs. The tube is secured to the rear face of the back of the safety seat in spaced relationship therewith whereby the a three-point safety belt may be located with its horizontal lap belt in contact with the vertical legs beneath the midpoint of the safety seat and with its transverse shoulder belt in contact with the horizontal leg above the midpoint of the safety seat. This relationship of components will securely hold the child safety seat with respect to the car seat in which it is utilized.

Abstract: A molded solid softball of a unitary substantially spherical body having simulated stitching including protrusions and indentations on the outer surface integral with the body of the ball and further having simulated holes adjacent the outer edges of the stitching. The stitch holes extend into the body a distance sufficient to simulate the depth of the stitching holes or a standard stitched leather-covered ball. The depth of the stitch holes is between 0.040 and 0.070 inches.

Abstract: A method of constructing a mold for making game balls which comprises inserting pins of a predetermined length in the stitch holes of a stitched leather ball, depositing metallic mold material on the surface of the ball so as to cover the pins, dividing the metal/master assembly into mating halves, each half being symmetrical with respect to the stitching on the ball, and removing the master including the pins from the ball.

Abstract: An infant swing having a base, upwardly extending legs, and a coil spring-wound motor mounted on said legs, with the axis of said coil spring motor extending at a predetermined angle from the vertical above said base. A carriage is mounted to the motor such that it is driven by and oscillates about the axis of the spring. A swing support rod has one leg removably mounted to said carriage parallel to the axis of the spring, with the other leg extending substantially vertically downward and terminating in a substantially horizontal radle for supporting an infant seat beneath the carriage, whereby the oscillatory motion of the carriage causes the seat to swing in a substantially horizontal arcuate path. The infant seat is removably mounted to said cradle.

Abstract: A hanger assembly for supporting a spring from a crib having a plurality of closed loop brackets mounted on each corner post of the crib and a Z-shaped hanger mounted at each corner of the spring frame. One end of the hanger extends outwardly from the spring frame so as to mate with the associated bracket. The outer end has a depending lip which extends below the bracket when the spring is hung in place. Accordingly, the spring must be lifted vertically and moved horizontally in order to remove the hanger from the bracket.

Abstract: A midsize tennis racket is disclosed which utilizes two arcuate bridges, inverted with respect to the arc of the head of the racket, and includes grommets at opposite ends of the head in order to shorten the length of the center main string so as to provide more uniform power response in the central hitting area. A selected number of the center main strings are crisscrossed between the arcuate bridges and their support locations on the frame. The construction provides the playability of a small headed racket while maintaining the stability of a large headed racket. Further embodiments are disclosed which effectively shorten the length of the main strings by effectively creating two arcuate bridges. In one embodiment, the arcuate bridges are formed by elongated projections which have boreholes at their distal ends. In a further embodiment, inelastic loops are used to form the arcuate bridges.

Abstract: A method for packaging a playing ball so as to provide a partially exposed surface of the ball which comprises the steps of imprinting selected indicia on a heat shrinkable plastic film loop, placing the loop about the ball in frictional contact with a portion of the surface of the ball, applying heat to the loop and the ball to shrink said loop so as to wrap a circumferential section of the ball, and removing the heat and permitting the loop to cool about the ball in its shrunken state. If the ball is partially deflated, the loop is placed about the ball and the ball is inflated until frictional contact between the ball and loop occurs with subsequent heat application.

Abstract: A dampening mechanism for sports implements such as tennis rackets comprising an elongated vibratable member formed of an elastomeric, energy absorbing material. The vibrational member is integral with a grommet strip which mates with the underside of the yoke of the racket and the string holes therethrough. The unit is held firmly to the frame, with the vibrational member fixed within the throat of the frame below the yoke, by the strings when the racket is strung.

Abstract: Disclosed is a unified set of golf clubs, from wood clubs through wedge clubs, in which loft and lie angles, face progression, and club lengths are coordinated and correlated. The center of gravity of each club is lower, further back and more centered on the club face than is usual. In addition, each golf club of the set features a sole width of at least 1.25 inches. The center of gravity of each club head is located no more than 0.7 inch above the sole and at least 0.5 inch from the centerline of the club shaft.The club heads of this invention may be fabricated as a hollow metal shell. Alternatively, the club heads may be formed of a low density, high strength material such as reaction injection molded polyurethane. In such an embodiment weighted inserts are molded into and encapsulated within the polyurethane.

Abstract: A child's car seat is disclosed which consists of two basic parts, the first comprising a base, frame, and back, and the second consisting of a seat removably secured to the base adjacent the back whereby, when the seat is secured to the base, a child's car seat is provided for infants and small toddlers and, when the seat is removed from the base, a booster seat is provided for larger children. The seat includes a split shield secured to the seat portion so as to be used in both the car seat and booster seat configuration. A harness, including a crotch strap, is provided for use when the car seat configuration is used.
