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  
         [0001]    The present invention relates to a toy football, and more particularly to a propeller enhanced toy football.  
         BACKGROUND OF INVENTION  
         [0002]    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.  
           [0003]    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  
         [0004]    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.  
           [0005]    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.  
           [0006]    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  
       [0017]    [0017]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.  
         [0018]    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 .  
         [0019]    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 .  
         [0020]    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 .  
         [0021]    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 preselected 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.  
         [0022]    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.
