Ball with an improved bladder carcass securely engaging with multiple cover panels

Abstract

A ball includes multiple cover panels respectively multiple ribs protruded on a bladder carcass so as to define a panel recess between two adjacent ribs. Each rib has a first step and a second step respectively formed on a side face of the rib such that a first receiving space to receive therein the cushion and a second receiving space in communication with the first receiving space to receive therein the cover panel are defined between the two adjacent ribs. Engagement of the cushion and the cover panel to the bladder carcass is enhanced.

1 . A ball comprising: 
 multiple cover panels;    multiple cushions; and    multiple ribs protruded on a bladder carcass so as to define a panel recess between two adjacent ribs, each panel recess having a shape the same as that of a corresponding one of the cover panels, each rib having a first step and a second step respectively formed on each side face of the rib such that a first receiving space to receive therein the cushion and a second receiving space in communication with the first receiving space to receive therein the cover panel are defined between the two adjacent ribs and the cushion is able to engage with a bottom face defining the panel recess as well as a sidewall defining the first receiving space and the cover panel is able to engage with a bottom face and a sidewall of the second receiving space so that engagement of the cushion and the cover panel to the bladder carcass is enhanced.    
     
     
         2 . The ball as claimed in  claim 1 , wherein the sidewall of the first receiving space and the sidewall of the second receiving space are inclined relative to the bottom defining the panel recess so as to secure engagement of the cushion and of the cover panel to the bladder carcass.  
     
     
         3 . The ball as claimed in  claim 1 , wherein the cushion has a width substantially the same as that of the first receiving space and the cover panel has a width substantially the same as that of the second receiving space.  
     
     
         4 . The ball as claimed in  claim 2 , wherein the cushion has a width substantially the same as that of the first receiving space and the cover panel has a width substantially the same as that of the second receiving space.
