Abstract
A soft toy football having guiding fins projecting from its back end is enhanced by a motor driven propeller.
Description




FIELD OF THE INVENTION




The present invention relates to a toy football, and more particularly to a propeller enhanced toy football.




BACKGROUND OF INVENTION




Toy soft foam elastomer footballs are known, and because they are soft and usually of a smaller size than regulation footballs, they are recommended for indoor play or play with or among small children.




Toy footballs or the like with rearwardly projecting fins are also known, e.g. see U.S. Design Pat. Nos. D346,001; D361,811; and D442,655; and U.S. Pat. Nos. 5,284,341; 5,269,514 and 3,225,488. The fins tend to help regulate the flight path of the football to assume a more even and regular flight path after it has been thrown.




SUMMARY OF INVENTION




However, no toy footballs are known which have both fins and a motor driven propeller, the latter of which provides improved stability and aerodynamic properties.




It is therefore an object of the present invention to provide a toy football of the above general type, which provides improved stabilization and/or overcomes deficiencies in the prior art.




The present invention comprises a soft football made of foam plastic or foam rubber or the like, preferably with a skin, having a tubular recess in which resides a battery pack and motor. Attached thereto, and extending from the back end of the football, are a plurality of axially and radially projecting aligned fins and a propeller which is driven by the aforementioned motor. The fins and motor driven propeller cooperate to provide improved stabilization for the football during flight.

DETAILED DESCRIPTION OF EMBODIMENTS





FIG. 1

is a perspective view of a propeller enhanced football


10


according to a first embodiment of the present invention; and comprises a football shaped, soft front body portion


12


formed of foamed rubber or foamed plastic, preferably with a smooth outer skin, and a rear module


14


comprising a housing


16


which normally fits and is retained within the front body portion


12


, and which has a plurality of fins


18


extending rearwardly therefrom, as well as a propeller


20


at or adjacent the rear end thereof.




As shown in

FIG. 8

, the housing desirably is provided in two halves


16


A and


16


B, for easy access to the interior thereof which houses a small electric motor


22


wired to one or more batteries


24


through a timer


26


. Extending from the motor


22


is a shaft


28


. Either such shaft


28


itself or an extension


30


therefrom extends through a soft core


32


to which the fins


18


are connected or are made a part thereof. The shaft


28


,


30


then extends back out through the end of the core


32


and its distal end is connected to the propeller


20


.




The body portion


12


and the rear module


14


are desirably locked together such as by a bayonet connection including a slot


34


as shown in FIG.


9


. Thus, the rear module


14


, after insertion of the battery or batteries into the housing


16


, is easily assembled with the front body portion


12


by merely sticking the housing


16


into the elongated cavity


36


within the front body portion


12


and twisting to engage the bayonet locking mechanism including the bayonet slot


34


. Where such a bayonet type locking mechanism is used, it will be understood that the housing


16


will carry a projection on its outer surface which will slide within the bayonet slot


34


.




The exterior parts of the propeller enhanced football


10


of the present invention are preferably made of soft materials, most preferably soft foam rubber or soft foam plastic, these parts including the exterior and bulk of the front body portion


12


, the fins


18


and the core


32


. The blades of the propeller are desirably thin, soft and flexible, e.g. made of flexible plastic, so as to not cause any injury to the players which may include small children. One portion of the propeller-enhanced football


10


of the present invention which is made of a harder material is the housing


16


and its contents, and also the collar portion


38


.




Mounted on the collar portion is a switch button which closes the circuit between the battery


24


and the motor


22


. The timer can be set to open the circuit after any pre-selected time, preferably between five and ten seconds, although it will be understood that any reasonably short time can be pre-selected for the timer, e.g. seven seconds, ten seconds, fifteen seconds, etc.




In use, the person throwing the propeller-enhanced football will press the starter button causing the propeller to spin, and will then throw the football


10


. The propeller will give the football


10


some enhanced thrust, increasing the distance the ball can be thrown and improving its stability in flight. After a predetermined time, e.g. seven seconds, the timer will break the circuit so as to turn the motor off.




The foregoing description of the specific embodiments will so fully reveal the general nature of the invention that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without undue experimentation and without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. The means, materials, and steps for carrying out various disclosed functions may take a variety of alternative forms without departing from the invention.




Thus the expressions “means to . . . ” and “means for . . . ”, or any method step language, as may be found in the specification above and/or in the claims below, followed by a functional statement, are intended to define and cover whatever structural, physical, chemical or electrical element or structure, or whatever method step, which may now or in the future exist which carries out the recited function, whether or not precisely equivalent to the embodiment or embodiments disclosed in the specification above, i.e., other means or steps for carrying out the same functions can be used; and it is intended that such expressions be given their broadest interpretation.
