CA 2291053

A golf ball having a smaller and lighter core (10) and metal particles, or other heavy weight filler materials, in the cover (14, 16). Preferably, the particles are included in a relatively thick inner cover layer (or mantle) (14) of a solid, three-piece multi-layered ball. In another preferred version, one or more patterns (32, 42, 52, 62, 72, 82, 92, 104, 116, 118, 122) of weighting material are incorporated in the ball, and most preferably along the outer periphery of the ball so that the pattern (32, 42, 52, 62, 72, 82, 92, 104, 116, 118, 122) is visible along the ball's exterior. The reduced size and weight of the core (10) produces a ball which meets, or is less than, the 1.62 ounce maximum weight limitation specified by the United States Golf Association. The ball has an increased moment of inertia and/or greater radius of gyration and thus generates lower spin. The ball exhibits enhanced distance without substantially affecting its feel and durability characteristics.

La présente invention concerne une balle de golf dont le noyau est léger et de petites dimensions (10), et dont l'enveloppe (14, 16) est chargée de particules métalliques ou d'un autre matériau de lest. Les particules sont incluses de préférence dans une couche de couverture intérieure, ou "manteau", (14) qui est relativement épaisse pour ce type de balle à plusieurs couches en trois parties. Selon une autre réalisation préférée, le matériau de lest incorporé dans la balle forme un ou plusieurs motifs (32, 42, 52, 72, 82, 92, 104, 116, 118, 122), de préférence sur la périphérie extérieure de la balle, de façon que les motifs (32, 42, 52, 72, 82, 92, 104, 116, 118, 122) soient apparents à l'extérieur de la balle. Les dimensions réduites et la légèreté du noyau de la balle (10) donnent une balle conforme à, ou en dessous de, la limite maximale de masse édictée par la "United States Golf Association". Le moment d'inertie de cette balle est ainsi augmenté, le rayon de giration plus grand, ce qui donne un effet de balle moins important. Cette balle présente ainsi des caractéristiques de distance accrues, sans pour autant affecter le toucher de balle ni la résistance à l'usure.
