ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a ball, and more particularly to a base ball or a soft ball having a molded and raised seam and having a leather covering attached to the outer peripheral portion thereof.
2. Description of the Prior Art
Typical base balls comprise a pair of 8-shaped cover pieces secured together on a core of the ball with stitches, and having a raised seam formed or provided between the 8-shaped cover pieces. U.S. Pat. No. 5,772,544 to Yang, and U.S. Pat. No. 6,190,273 B1 to Maxey et al., discloses two of the typical base balls. However, water or the like may permeate into the core of the base ball through the stitches provided between the cover pieces. In addition, the cover pieces should be secured together manually with the stitches and may not be produced in mass production.
U.S. Pat. No. 4,729,566 to Molitor discloses the other typical ball including a molded cover formed or provided on the outer peripheral portion of a molded core. However, the molded cover is made of plastic or rubber or synthetic material, that has a completely different grasping or gripping feeling for the pitchers, as compared with the real base balls that have leather cover layer provided thereon.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional balls.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a ball including a molded and raised seam and including a leather covering attached to the outer peripheral portion thereof.
In accordance with one aspect of the invention, there is provided a ball comprising a core including an outer peripheral portion, and two 8-shaped cover pieces secured onto the outer peripheral portion of the core, and made of leather material. The cover pieces are preferably secured onto the core with adhesive materials.
A water-proof outer layer is further provided on the outer peripheral portion of the core for protecting the core and for preventing the core from being wetted, the 8-shaped cover pieces are secured onto the outer layer.
The outer layer includes an 8-shaped seam extended outward therefrom for forming two 8-shaped recesses therein and for receiving the 8-shaped cover pieces.
The seam includes a plurality of bulges extended radially outward therefrom for simulating the raised seam or stitches of the typical balls.
