Benefits of technology

[0007]The present invention concerns a golf ball with dimples comprising markings that are raised geometric elements. The raised markings interact with and become components of dimples themselves rather than being additions or replacements for dimples. Innovatively, the markings increase the perimeter of dimples thereby providing a means to control and improve aerodynamic performance.

Problems solved by technology

However, such conventional ink-based indicia are not sufficiently durable (impact resistant) to withstand multiple impacts with a golf club.

Embodiment Construction

[0015]Referring to FIG. 1, a golf ball 10 includes a spherical outer surface that has at least two types of dimples 15 and 20 formed thereon. The first type of dimple 15 is a conventional spherical dimple. The second of type of dimple 20 is a combination of a conventional dimple and markings 30, which are raised geometric elements having substantially the same elevation as the undimpled land area 40. The markings 30 interact with and become integral components of dimples 20 rather than being additions or replacements for dimples. Innovatively, the markings 30 increase the “total individual perimeter value” of one or more dimples 20, and the “aggregate global dimple perimeter value” of a golf ball 10, as explained below. Such increased perimeter quantities provide a means to control and improve aerodynamic performance.

[0016]As used herein, the quantity “aggregate global dimple perimeter value” (“AGDPV”) represents the sum of perimeters for all dimples 15, 20 in a given golf ball 10. ...

Abstract

The present invention comprises a golf ball with dimples. Some of the dimples have markings that are raised geometric elements having substantially the same elevation as the undimpled land area. Innovatively, the markings interact with and become components of dimples themselves rather than being additions or replacements for dimples. Innovatively, the markings increase the total perimeter value of one or more dimples, and the aggregate dimple perimeter value of a golf ball. Such increased perimeter quantities provide a means to control and improve aerodynamic performance.

Description

FIELD OF THE INVENTION[0001]The present invention generally relates to golf balls. Particularly, the invention is directed to improved golf balls having a plurality of dimples forming indicia.BACKGROUND OF THE INVENTION[0002]Golf balls are routinely marked with various surface indicia, such as the manufacturer's logo and trademark, and the play number, which allows golfers using the same type of golf ball to distinguish one player's ball from that of another. Additional symbols that may also be applied to golf balls include custom figures for promotional purposes as well as specific marks reflecting manufacturing information. There are different approaches commonly used, mostly water-based or solvent-based ink printing systems, for adding indicia to the dimpled outer surface of a golf ball. However, such conventional ink-based indicia are not sufficiently durable (impact resistant) to withstand multiple impacts with a golf club.[0003]During the first half of the 20th century it was ...
