FOOTBALL CATAPULT
Abstract
A catapult for propelling a toy football includes a pair of
parallel upright panels forming a forwardly facing ramp for
supporting the ball, and a lever arm pivotally mounted between the
panels. The lever arm includes a kicking leg integrally supporting
a kicking foot in position to be in contact with the ball when it
is on the ramp and an impact arm integral with and extending
outwardly from the leg adjacent the point of pivotal mounting and
rearwardly from the ramp in position to impart a kicking action to
the ball when the arm receives a manual impact. The kicking foot,
when in a rest position, will be positioned above the football
supporting ramp. When a football is positioned on the ramp the
lever arm will be caused to be pivoted. The kicking foot will thus
remain in engagement with the football until which time the
football is forced off the ramp by the action of the kicking
foot.

Description
BACKGROUND OF THE INVENTION
This invention has relation to miniature football games and more
particularly to such games where a football is propelled into the
air by the use of some mechanical entity.
Football catapults formerly of commerce included those of the
spring loaded type in which the amount of power imparted to the
ball was predetermined by the loading of a spring. In many of these
devices, the positioning of the ball with respect to the catapult
is predetermined and hence the accuracy and distance which the ball
is propelled is a function of the mechanical biasing device and
predetermined positioning and not fully subject to the skill and
judgment of the player. In some of these devices, it is not even
possible to position the catapult with respect to the area where it
is desired to project the ball, so very little element of skill
enters into the use of such devices.
Furthermore, these devices, being powered by mechanical entities
and/or using biasing means such as springs and the like, are
subject to wear and breakdown after extensive use. Almost
invariably such devices are made of metal parts and as such as
subject to damage due to neglect and abuse.
SUMMARY OF THE INVENTION
In a football catapult, made according to the present invention, a
forwardly facing ramp is defined by the upper parallel edges of two
parallel supporting panels. These ramp-defining edges terminate in
an imaginary curved surface normal to the panels and roughly
approximating the profile of the toy football to be propelled over
a central half of the length of the ball. The ramp extends from the
horizontal toward the vertical and will support a football from a
position with its major axis in a horizontal plane to a position
with its major axis within approximately fifteen degrees of the
vertical.
A lever arm is pivotally supported between the two panels and
includes a kicking leg integrally supporting a kicking foot at and
end thereof opposite said point of pivotal support. An impact arm
extends integrally outwardly from the kicking leg at an end thereof
adjacent the pivotal support, and extends rearwardly away from the
ramp. The construction is such that the lever arm pivots freely and
hangs with the kicking foot extending well up through the imaginary
curved surface defining the upper edges of the ramp when the ball
is not on the ramp. When the ball is on the ramp, the foot contacts
the ball at a middle portion of the ramp. This forcing of the
kicking foot backward by the weight of the ball as it is placed on
the ramp brings the impact arm to a position slightly below the
horizontal. Then when a fist or edge of a hand is brought down
sharply on the impact arm, it will impart a kicking action to the
ball and will propel it from the ramp.
With some exercise of skill and judgment in placing the ball on the
ramp, the ball can be made to leave the ramp at an angle anywhere
from slightly forward from the vertical to about 25.degree. above
the horizontal. By positioning the major axis of the ball parallel
to or in angular relationship to the plane of movement of the foot,
simulations of end-over-end place kicks or drop kicks and of spiral
or wobble punts can be obtained.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is a perspective view showing the catapult of the invention
at rest and without a football thereon;
FIG. 2 is a side elevational view of the catapult of FIG. 1 with
the nearest panel and a portion of the base removed;
FIG. 3 is a side elevational view at a reduced scale of the
catapult, but with a football positioned thereon to be catapulted
at a relatively low angle therefrom; and
FIG. 4 is a side elevational view as in FIG. 3, but with a football
positioned so as to be kicked end-over-end at a relatively high
angle.
DESCRIPTION OF THE PREFERRED EMBODIMENT
In the drawings, a football catapult 10 includes a pair of spaced
apart parallel panels 11 and 12 mounted on a base 13 to which a
base block 14 has been added to give additional stability to the
base and to the panels. This base block also has the function of
absorbing any energy from the hand which imparts the impact to the
impact arm as will be explained later.
A lever arm 15 is pivotally mounted on an axle 16 to freely swing
from position between the two panels 11 and 12. This lever arm
includes a kicking leg 17 and an integral kicking foot 18 extending
outwardly therefrom at an end thereof opposite the axle 16. An
impact arm 19 also extends integrally outwardly from the kicking
leg 17 to form a part of the lever arm 15, and an upward portion of
that impact arm is constituted as an impact block 20.
As best seen in FIGS. 1 and 2, when there is no toy football
positioned on the top edges of the panels, the lever arm will lie
under the force of gravity in position with the kicking foot 18
extending outwardly between the panels. When a football 24 is
placed on the top edges of the panels, as seen in FIGS. 3 and 4,
the weight of the football will be such that it will cause the
kicking foot 18 to be depressed to bring the impact arm 19 and its
impact block up to a position approaching the horizontal.
The top edges of the panels 11 and 12 define a football positioning
ramp, indicated generally at 25. These edges terminate and this
ramp is defined by an imaginary curved surface normal to the panels
and roughly approximating the profile of the toy football over a
central half of the length of the ball. This is best seen in FIG.
4. In that figure, note that the ramp extends from horizontal, as
at 26, to a line approaching the vertical, as at 27, and notice
that this ramp surface thus defined does approximate the shape of
the football along that portion thereof.
For clarity of explanation, the center of gravity of the football
has been designated 28. As will be understood from a consideration
of FIG. 3, with the football positioned as shown, and when the
impact arm and block 19 are struck soundly with the side of the
hand of the player, the kicking foot 18 will impart a component of
force to the football, the resultant of which will be at least
slightly above the center of gravity of the ball, and so the
resultant flight of the ball through the air will be at a low
angle, as indicated in dotted lines.
Similarly, with the football positioned as seen in FIG. 4, the
kicking foot 18 will impart a component of force which will be
below the center of gravity 28 and the motion of the ball will be
end-over-end, simulating a drop kick or place kick, but the
trajectory of the ball will be at a sharp upward angle, as
indicated in dotted lines and the arrows in that figure.
In playing a football game in accordance with the present
invention, toy goal posts can be set up across the yard or across
the living room as desired, and the "kicker" can position the
football on the catapult as he chooses and can strike the impact
block at 20 with his fist or hand to send the football in the
direction toward the goal posts. The force of the impact on the
impact arm, together with the positioning of the football on the
ramp, will determine the accuracy with which the player is able to
approach or "kick" the ball through the goal posts.
As a refinement, it has been discovered that when the ball is
positioned on the horizontal portion of the ramp, with its major
axis in nonparallel relationship to the plane of the panels and to
the axle 16 of the lever arm, either a spiral kick or a wobbly kick
simulating a punt can be obtained.
In one form of the invention, the entire catapult, except the axle,
is made of wood and in another form of the invention, the base 13
and the panels 11 and 12 are made of fiberboard with the remainder,
except the axle, being made of wood. It is to be understood that
the entire device could be made out of plastic or even metal. It is
preferable, however, to provide something no harder than wood as
the impact block to take the striking force of the hand. Further, a
covering or cushioning can be placed over the base block 14 at a
position immediately below the impact block to protect the hand
should the force employed be so great as to crash down painfully on
this base block.
While reference has been made herein to a toy football, nothing
limits the catapult of the invention from being used on larger
footballs.
