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.
