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.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a ball, and more particularly to a ball with an improved bladder carcass that securely engages with multiple cover panels. [0003] 2. Description of Related Art [0004] A conventional basketball generally comprises a spherical bladder carcass, a reinforcing lining layer enclosed in the bladder carcass and a spherical cover made of leather or synthetic leather such as polyurethane (PU) or polyvinyl chloride (PVC) and enclosing the bladder carcass. However, the basketball provides a strong resilient force when used so that a person playing the basketball feels painful when passing or shooting the basketball. [0005] Another conventional basketball has been developed to improve the softness. The improved basketball has a bladder carcass made of foamed or sponged rubber and a spherical cover attached to the bladder carcass. The rubber bladder carcass provides fine softness, yet has a loose ...

AI Technical Summary

Benefits of technology

[0011] The primary objective of the present invention is to provide a ball with an improved bladder carcass that securely engages with multiple cover panels to prolong life span of the ball.

[0012] In one aspect of the present invention, the bladder carcass of the ball includes multiple protruded ribs and multiple cushions. Each rib has a first and second step respectively formed on two opposed side faces of the rib so as to define between two adjacent ribs a panel recess. The cushion is attached respectively to the first step in the panel recess. The cover panel is adhered respectively the second step in the panel recesses. The cushion has a width substantially the same as that of the first step of the panel recess and the cover panel has a width substantially the same as that of the second step of the panel recess so that the cover panel and the cushion respectively engage independently with a sidewall of the corresponding rib. Thus engagement between the bladder carcass, cushion and the cover panels is enhanced.

Problems solved by technology

However, the basketball provides a strong resilient force when used so that a person playing the basketball feels painful when passing or shooting the basketball.

However, the thickened cover has a high cost.

However, the basketball surface structure still can not provide complete engagement between the cover panel (40) and the bottom face defining the panel recess (32) because the side face of each cover panel (40) engages with the sidewalls surrounding the panel recess (32).
