FIELD OF THE INVENTION

The present invention in general relates to an impact resistant ball and a process of forming the same; and in particular to an impact resistant ball having an inflatable bladder contained within a shell, a gripper and a skin contacting an outer surface of the shell.

BACKGROUND OF THE INVENTION

Games involving the setting up, striking, and knocking down of individual game pins set up on a playing surface or a game board often require an object such as a ball to effectuate the striking and knocking down of individual game pins. Typically, with this type of game, a player throws or otherwise sets in motion an object such as ball towards the individual game pins. Depending on the rules of the specific game being played, the general goal is usually to strike or knock down the individual game pins with an object such as a ball. A single game can be made up of several rounds. For example, a single game may include 10 rounds, where each player gets 2 or more throws per round. A player's progress can then be scored in a variety of ways. For example, a player could be rewarded a predetermined amount of points for the number of pins knocked down per throw or in a competitive timed fashion.

Individual game pins are often set up on a game board. The game board can be constructed from a variety of materials illustratively including wood, plastic, concrete or metal. Such materials are not very forgiving on an object such as a ball upon impact of the ball with the game board. A natural incident to games requiring the throwing of a ball towards individual game pins is the inevitable repeated impact of the ball with the game board and the individual game pins as well as other objects surrounding the playing area. Such repeated impact causes nicks and other damage the ball. Sometimes, in the case of a ball with an inflatable bladder, the damage sustained from a single impact could be complete penetration of the ball's outer surface as well as the inflatable bladder contained within the ball. The risk of impact related damage presents challenges which become exacerbated when playing a game made of up several rounds, where a ball may be thrown between 50 and 100 times per game.

One challenge in particular is the cost of replacing damaged balls. A challenge that becomes more amplified when playing a game made up of several rounds, and even more amplified when the game uses a ball that must be purchased for a non-nominal cost such as an American football. If the game is intended to be played in a private setting such as a backyard or the beach, a one-time purchase of the game board and pins, along with the purchase of one game ball may be all that is required to begin playing the game. However, if the damage sustained the ball incident to playing the game is so severe that the ball must be frequently replaced, the replacement cost may be prohibitive. For example, in a game such as FOWLING™ which currently uses American footballs, the average life expectancy of one American football is less than one week. An American football has an inflatable bladder surrounded by a skin which is laced together to form the football. This construct lacks additional support and impact-resistance under the skin and as a result, an American football has a finite elasticity leaving it susceptible to nicks and other damage including penetration of the skin and puncture of the bladder after repeated impacts with other objects including a game board. If the game is intended to be played in a public setting such as a for-profit facility, then the owner of the facility usually provides the game board, game pins and balls. In this scenario, if the damage sustained the ball incident to playing the game is so severe that the ball must be frequently replaced, the replacement cost may be so prohibitive that it cuts into the profits of running such a facility or even worse, drives up the operating costs to a point where the business is no longer profitable at all.

Another challenge stemming from the need to replace a ball subject to repeated impact and frequently damaged, is repeated game stoppage in order to obtain a new ball. Such repeated game stoppage could negatively impact the pace, and ultimately the overall enjoyment of the game. This inefficiency becomes even more acute in the context of league play or multiple games being playing back-to-back which increases the frequency with which game balls are damaged and replaced.

A further challenge stemming from using a game ball such as an American football is the size of the gripper made up of the laces used to sew the ball together. A regulation sized American football can be hard for a large segment of the population to grip and properly throw owing to the relatively small size of the gripper compared with the overall size of the ball. Women, children, young adults and even some adult males have trouble securely gripping the gripper which leads to difficulty in properly throwing the American football in a manner that achieves a spiral rotation of the ball. As such, a game that requires the throwing of an American football marginalizes a large segment of the population who otherwise might enjoy playing the game if the ball was more amenable to a greater range of hand sizes. This negatively affects the appeal, marketability and ultimate success of such a game.

Current balls used in the industry to address the pitfalls stemming from using a ball frequently damaged after repeated impacts with other objects such as a game board and game pins are not satisfactory in that they do not provide a ball with increased impact resistance under the skin nor do they provide a ball with an increased length gripper able to accommodate a greater range of hand sizes.

Thus, for games that require the throwing of a ball towards game pins set up on a game board with the goal of striking and knocking down the game pins with the ball, there exists a need for an impact resistant ball with an increased resistance to damage sustained from repeated impacts with objects such as the game board and game pins. There further exists a need for an impact resistant ball with an increased length gripper able to be properly gripped and thrown in a spiral rotation by a larger segment of the population including those with smaller hand sizes such as women, children, the elderly and young adults. There also exists a need for a process of forming an impact resistant ball with an increased length gripper

SUMMARY OF THE INVENTION
