1. The Field of the Invention
The present invention relates to a solid foam football that has a series of tubular holes that are located along the longitudinal axis of the football, so that when the football is submerged in water and subsequently thrown will allow the water to leave the ball in a spiraling fashion.
2. Description of Related Art
Many different type of footballs have been developed that can be used by sports enthusiasts of all ages and skills. There is a soft foam football under the trademark NERF. The NERF football is soft and easy to throw and catch.
These types of football are made of polyurethane, producing a soft ball. Different variations of the NERF football have been developed. U.S. Pat. No. 5,676,611 describes a foam football that forms an outer shell that surrounds a hollow inner chamber, this helping to create a spiraling motion when thrown. Foam footballs with rearwardly extending fins have also been made which promote a tight spiraling motion have been described in U.S. Pat. No. 4,772,020. U.S. Pat. No. 5,997,422 describes waterproof game balls comprising elastically stretchable panels allow for these balls to be used in and around water.
Producing a football that can be used in the pool or at the lake, river, ocean and will produce a spiral spray when thrown is desirable. The foam type of football is softer and easier to grip than a regular football. It would be desirable to produce a football that is fun to use around the water and produces a special effect spiral spray when submerged and thrown.
The present invention is an ellipsoid or prolate spheroidally shaped foam ball that is constructed with symmetrically placed tubular holes along the surface of the ball. When the ball is submerged in water the tubular holes will fill with water. These tubular holes will form the paths of least resistance. As the ball is thrown in a forward direction with a spiraling motion the water in the holes and also absorbed by the ball will because of centrifugal force leave the ball producing a spiraling spray. This ball is unique in that can be thrown either wet, producing the spray or can be thrown dry like and of the different foam footballs available.
A football as seen in
The invention is preferably made of polyurethane and has a density that is less than water to allow the toy to float in water. The invention may be thrown without first being submerged in water like any football type toy or after submerging the toy in water which will allow the water 18 to be expelled from the tubular holes 12 and spray water 18 in a spiral fashion 20 while the invention is in the air.
From the foregoing description, it can be seen that the present invention comprises an improved foam game ball—football 10. It will be appreciated by those skilled in the art that obvious changes can be made to the embodiment in the foregoing description without departing from the broad inventive concept thereof. The invention may be embodied in other specific forms without departing from the spirit or essential properties. An example of this would be to make the invention in the form of a baseball or volleyball. Another example would be to vary the number of tubular openings 12 or change the size of the tubular openings 12. It is therefore understood that this invention is not limited to a particular embodiment or shape disclosed.
The claims are intended to cover all obvious modifications thereof which are within the scope and the spirit of the invention defined in the claims above.
