Abstract: A dimpled configuration for a golf ball wherein the dimples are arranged in a modified icosahedral lattice comprising a first set of five adjacent triangles on either side of the equator of the ball, with the vertices of each of the triangles being located at each pole of the ball and the sides opposite the polar vertices being spaced a distance from the equator of the ball. A second set of five triangles smaller than the first set of triangles equally spaced between the first set of triangles and the equator of the ball, each of the second set of triangles having a vertex common with adjacent ones of the first set of triangles, with the leg opposite the common vertex being parallel to but spaced from the equator.

Abstract: A tennis racket having a graphite fiber containing frame with an opening at the head end constituting a bow and with a handle pallet at the handle end. The handle pallet is formed of a soft, dense, indexable urethane. The bow is formed with a common cross-sectional configuration enlarged in the direction of the axis of the opening and located around the majority of the opening. The racket also includes a grommet strip formed of a soft, durable, wear resistant polyurethane-polycarbonate blend secured to the radially exterior edge of the bow around the majority of the opening.
Abstract: A foldable playyard for safe occupation by a child comprising in combination an essentially rectangular upper support formed of four pair of rods each centrally coupled by a hinge; an essentially rectangular lower support formed of four of rods each centrally coupled by a hinge; four vertical rails interconnecting the corners of the upper and lower supports to retain the upper and lower supports in a box-like configuration with the rods of the upper and lower supports pivotally coupled to the vertical rails to allow for pivoting the rods of the upper support and lower support between horizontal orientations when the playyard is in an unfolded condition for operation and use and vertical orientations when the playyard is in a folded condition for storage; a unitive fabric assembly comprising four vertically disposed panels each coupled between a pair of rods of the upper support and lower support and adjacent vertical tubes, the fabric assembly also including a lower horizontal panel stitched to the vertically
Abstract: An improved golf club comprising a shaft with a head at the tip end and a grip at the butt end, the grip adapted to be held by the hands of the player and formed of an elastomeric material having a plurality of curved grooves, the grooves being in a first set oriented generally axially at the butt end of the grip and therebeyond in a second set generally axially on the bottom surface and generally circumferentially on the top surface and further including a third set of grooves oriented generally circumferentially at the tip end of the grip.
Abstract: A high chair tray latch mechanism comprising a housing secured to the underside of a high chair tray with movable latches on the opposed side of said housing for engaging apertures in the arms of the chair. A bell crank is rotatably mounted centrally within the housing between the movable latches. First and second rigid rods are pivotally attached at one end to opposite arms of the bell crank and the first and second arms are pivotally attached at their other ends to their respective latches. The crank includes a spring which rotatably biases the crank in a direction to engage the latches with the holes in the arms of the chair. A cable is connected between the crank an a lever located on the underside of the forward part of the tray. Manual squeezing of the lever relative to the tray foreshortens the cable so as to rotate the crank.
Abstract: An improved high chair comprising a seat with a back component and a bottom component for receiving a child thereon; a plurality of tubes for strengthening the seat and extending on opposite sides of the seat for forming arm rests; a plurality of legs for supporting the seat at a proper height; a tray removably positioned on the arm rests in front of the seat above the bottom component; and a seat belt assembly comprising a pair of generally horizontally extending waist straps each coupled at its remote end to a portion of a high chair seat with a buckle part at its front end, a crotch strap permanently secured to a front central extent of the seat portion and having a free front end, and a main buckle permanently attached to the free end of the crotch strap with the main buckle also having a pair of attachment mechanisms for removably receiving the buckle parts of the ends of the waist straps.
Abstract: This invention is concerned with a reinforced panel device which is useful in the display and furniture arts. The reinforced panel device consist of a base and a header. By placement of the header on the base the various panel sections which make up the base are locked into a plumar relationship with each other. the base section of the reinforced panel device comprises a plurality of panel sections which are pivotly connected to each other. The header may comprise a single panel section or a plurality of panel sections which are pivotly connected to each other. The header may be permanently or detachably attached to the base. In accordance with the preferred embodiment the header is attached to the base via a connector plug having a camming end and a hook end.
Abstract: An improved restraining system for a child comprising in combination an infant carrier having a foot end and a head end and side edges therebetween, the carrier having finger receiving slots in its lower face; and a base having a foot end and a head end and side edges therebetween, and extending upwardly from its upper surface fingers pivotably adapted to releasably receive the slots and an inverted J-shaped hook at its foot end.
Abstract: An improved play yard having a lower horizontal support formed of rails, an upper horizontal support formed of rails and vertical support rails pivotably coupled therebetween, a central hub pivotably coupling the radially interior ends of the rails of the lower horizontal support and hinges coupling the rails of the upper horizontal support at intermediate locations. The hinges are adapted to be rotated about their axes between a locked position wherein the play yard is secure for operation and use and an unlocked position wherein the upper rails may be pivoted and the entire play yard collapsed upon the raising of the hub. Also disclosed is the hinge per se.
