Game ball with grip zones
First Claim
Patent Images
1. A game ball, comprising:
- an inflatable bladder; and
a cover layer surrounding the bladder, the cover layer being formed from a plurality of cover panels;
wherein at least one of the cover panels includes at least one grip zone formed from stitches created by a thread interwoven into the cover panel, the grip zone having a static coefficient of friction greater than a static coefficient of friction of an outer surface of the cover panel, when measured according to ASTM D1894 using the pebbled side of a Pattern 62 glass as the test surface;
wherein the at least one grip zone includes a first grip zone and a second grip zone, the first grip zone and the second grip zone both being located on the same longitudinal side of the at least one cover panel, and the first grip zone and the second grip zone forming a first set of grip zones;
wherein (a) the first grip zone has an annular shape, and the second grip zone has a different annular shape;
or (b) the first grip zone has a trapezoidal shape, and the second grip zone has a different trapezoidal shape.

Abstract
The present disclosure relates to a game ball having one or more grip zones that have greater frictional interaction compared to the outer surface of the game ball. The grip zones are made by stitching of a coated thread upon at least one cover panel to create the grip zone. The grip zone formed from the coated thread enhances the handling characteristics and playability of the resulting game ball.

5. A game ball, comprising:
-
an inflatable bladder; a cover layer surrounding the bladder, the cover layer being formed from a plurality of cover panels; and a lacing; wherein the plurality of cover panels includes at least one top panel that contacts the lacing and includes at least one bottom panel that does not contact the lacing; and wherein the cover layer includes a first grip zone, a second grip zone, a third grip zone, and a fourth grip zone on the cover layer, the first grip zone and the third grip zone being of identical shape and the second grip zone and the fourth grip zone being of identical shape to each other but a different shape from the first grip zone and the third grip zone, each grip zone having a static coefficient of friction greater than a static coefficient of friction of the cover layer, when measured according to ASTM D1894 using the pebbled side of a Pattern 62 glass as the test surface. - View Dependent Claims (6, 7, 8, 9, 10, 11)
