FIELD OF THE INVENTION
[0002] This invention relates to the field of sport projectiles,
and more particularly, to a non-standard or practice sport
projectile that includes a though-hole whose linear axis is
generally centered within the non-standard sport projectile, such
that when properly struck the projectile rotates around the center
cross section of the through-hole allowing airflow through the
opening during part of its rotation and blocking airflow during
part of its rotation (i.e., in a tumbling action instead of a
spiral action).
BACKGROUND
[0003] In many sports it is desirable to repeatedly practice a
physical motion. In various sports, an object strikes a projectile.
For example, it may be desirable to practice striking a golf ball
type projectile, baseball type projectile, or a football type
projectile.
[0004] In the sport of golf, practicing the physical motion of
swinging a golf club and striking a golf ball typically allows one
to become a successful golfer. In particular, the ability to
consistently repeat a golf swing, so as to obtain a consistent
flight of a golf ball, is important to becoming a successful
golfer.
[0005] In the sport of golf, there are many ways to in which
practice the art of striking a golf ball. A method most similar to
actually playing golf on a golf course is to hit or drive standard
or regulation golf balls at a driving range. However,
practice-driving ranges are often inconveniently located, and they
are expensive. Alternative to the use of a driving range, one can
use standard golf balls to practice in the backyard of a home, in a
vacant lot, or in an open field. However, practicing a full golf
swing in this type of a geographic area leaves much to be desired.
Often a backyard is not large enough to enable a golfer to use long
distance golf clubs, and vacant lots or fields are often not
readily available. Further, unless a golf swing is somewhat
consistent, retrieving standard golf balls can be a tedious and
time-consuming activity. Another alternative is to hit standard
golf balls into a net. However, this option prevents observation of
the ball's flight through the air. While a golfer can practice his
or her swing using this option, it is difficult to judge whether a
swing actually produces a desired flight of a standard golf ball.
Another alternative is to hit a non-standard, lightweight golf
ball, such as a foam or hollow plastic golf balls. However these
non-standard golf balls are so light that the "club's feel", as the
golf club impacts this type of non-standard golf ball, is
insignificant when compared to striking a standard golf ball. In
addition, the flight of such a lightweight, non-standard golf ball
is not a realistic experience. Furthermore, wind currents that may
have little influence on a standard golf ball can greatly influence
the flight of these non-standard, lightweight practice golf balls.
Yet another option is to practice hitting a standard golf ball into
a net using expensive tracking devices. These devices can monitor
the ball's speed, trajectory and spin, and then report a
theoretical flight path for the standard golf ball. None of the
above options are satisfactory, leaving most serious practice to
the driving range.
[0006] Thus, it is desirable to provide a practice or non-standard
sport projectile to be used when practicing a golf swing, when
practicing a football kick, and/or when practicing a baseball
swing. The non-standard sport projectile should mimic the "impact
feel" of a standard sport projectile. It should also mimic the
flight path of a standard sport projectile. Finally, the
non-standard sport projectile should be capable of use within a
relatively small geographic area.

flexural modulus; hitting the non-standard sport projectile with
the object; and causing rotation of the non-standard sport
projectile, and the axle providing an indication about alignment of
the object upon hitting the non-standard sport projectile.
[0009] In yet another embodiment, there is provided a non-standard
practice sport projectile for use within a relatively small
geographic area, the non-standard projectile for practicing a
striking motion associated with a sport, the non-standard sport
projectile comprising a generally rigid body comprising a material
with a high flexural modulus, the generally rigid body having an

DETAILED DESCRIPTION
[0059] As shown in FIGS. 1A and 1B, the present invention provides
a non-standard sport projectile, to be used like a golf ball, a
baseball, a football, etc., in the form of a three-dimensional,
rigid polymer, ball-shaped or spherical-shaped body 10 having an
annular void, through hole or opening 11 that extends entirely
through the center of body 10. In the embodiment shown in FIGS. 1A
and 1B, through-hole 11 has a circular cross section, and the
linear central axis of the through-hole 11 passes through the
geometric center of body 10.
[0060] Non-standard sport projectile 10 may have an external
spherical shape, or one of a number of external tubular shapes.
Generally, non-standard sport projectile 10 works better with
radiused sidewalls. While the majority of the description that
follows relates to non-standard or practice golf balls, one of
ordinary skill in the art will recognize that alternative
non-standard sport projectiles constructed and arranged in
accordance with the invention are possible. For example,
non-standard sports projectiles may include non-standard baseballs,
non-standard footballs, non-standard hockey pucks, non-standard
soccer balls, non-standard tennis balls, etc. Non-standard sports
projectiles may include ball or sports projectile that, when
struck, may have in-flight top spin or back spin as a desired
result.
[0061] FIGS. 2A-2C show other shapes of non-standard or practice
sport projectiles, in accordance with the invention, that have
different external shapes. FIG. 2A provides a top view of six
different size non-standard golf balls 12, each of which has a flat
top surface 13, a flat bottom surface 14 that is generally parallel
to top surface 13, a circular-cylinder side surface 15 and a
circular-cylinder through-hole 16 that extends through non-standard
golf ball 12 from its top surface 13 to its bottom surface 14. The
linear central axis of non-standard golf ball 12 extends
perpendicular to top surface 13 and bottom surface 14, the
geometric center of non-standard golf ball 12 lies on this center
axis, and the linear axis of through hole 16 is coincident with
this center axis.
[0062] FIG. 2B provides a top view of five different size
non-standard golf balls 15 having a somewhat flattened top surface
17, a somewhat flattened bottom surface 18 that is generally
parallel to top surface 17, a slightly convex-curved side surface
19, and a circular-cylinder through hole 20. The linear central
axis of non-standard golf ball 15 extends perpendicular to top
surface 17 and bottom surface 18, the geometric center of
non-standard golf ball 15 lies on this center axis, and the linear
axis of through hole 20 is coincident with this center axis.
[0063] FIG. 2C provides a top view of four different size
non-standard golf balls 21 having a somewhat flattened top surface
22, a somewhat flattened bottom surface 23 that is generally
parallel to top surface 22, a spherically-curved side surfaces 24,
and a circular-cylinder through-hole 25. The linear central axis of
non-standard golf ball 21 extends perpendicular to top surface 22
and bottom surface 23, the geometric center of non-standard golf
ball 21 lies on this center axis, and the linear axis of through
hole 25 is coincident with this center axis.
[0064] Side surfaces having other shapes will satisfy the spirit
and scope of the invention, for example elliptical shapes,
hour-glass shapes, etc. Further, while the above embodiments are
shown having circular-cylinder through-holes, other shapes for
through-holes are possible. These may include, but are not limited
to, through-holes shaped square, rectangular, elliptical,
triangular, etc.
[0065] Also, while three dimensional polymeric bodies such as shown
in FIG. 1 and FIGS. 2A-2C closely match the look-and-feel of a
standard golf ball, materials other than polymers can be
substituted to make non-standard sports projectiles in accordance
with the invention. For example, in the manufacture of non-standard
sport projectiles spring steel can be used to make non-standard
golf ball type projectiles, synthetic leather can be used to make
non-standard football type projectiles, etc.
[0066] The body of a non-standard sport projectile, in accordance
with the invention, is formed of a material that is strong enough
to absorb the propelling force that is applied thereto when the
non-standard sports projectile is stuck, such that the non-standard
sports projectile does not break or shatter as a result of this
striking force. Thus, for example, a stronger material may be
needed when making a non-standard golf ball type projectile, in
accordance with the invention, than would be needed when making a
non-standard football type projectile, in accordance with the
invention, due to the fact that the impact of a golf swing usually
generates a greater propelling force than does a football kick.
[0067] Further, in order to obtain a proper rotation or tumble of
the non-standard sport projectile after the projectile is hit, it
is desirable, but it is not required, that the non-standard sports
projectile be made of an elastic material that elastically deforms
at the point of impact, which material thereafter substantially
restores to its original shape after the non-standard sport
projectile leaves the surface of a striking body, be it a golf club
or the foot of a kicker.
[0068] As described above, non-standard sport projectiles may
include an annular (or ring shape) void or through hole that
penetrates completely through the non-standard sport projectile.
This annular void creates a surface-opening at two opposite
surfaces of the non-standard sport projectile, for example an
opening at both the "top" and an opening at the "bottom" of the
non-standard sport projectile. While shown above as generally equal
size opening in the top and bottom of the non-standard sport
projectile, the openings can have different sizes.
[0069] As shown in FIGS. 8A-8C, this annular void or through hole
26 may be circular or non-circular in cross sectional shape, having
straight walls that run the length of through hole 26 as is shown
in FIG. 8A, having walls that taper inward to provide a narrow
opening at the center or middle of through hole 26 as is shown in
FIG. 8C, or having walls that taper outward to provide a wider area
or flare at the center or middle of through hole 26 as is shown in
FIG. 8B. In each case, the central axis 27 of through hole 26
extends through the geometric center 28 of the non-standard sport
projectile. As one of skill in the art would recognize on reading
the disclosure, the through hole is not necessarily aligned with
the center axis, but it is believed the simulation to a standard
projectile is closer with the through hole aligned with the
center.
[0070] The most non-aerodynamic flight of a non-standard golf ball
30 that is constructed and arranged, in accordance with the
invention, is shown in FIG. 3E wherein the direction of the
non-standard golf-ball's spin is shown by arrow 31 and wherein the
axis 33 of the non-standard golf ball's through hole is aligned
with the direction of flight shown by arrow 32. In this attitude of
non-standard golf-ball 30, air flows through the non-standard golf
ball's through hole. The most aerodynamic flight of non-standard
golf ball 30 is shown in FIG. 3F in which the axis 33 of the
non-standard golf ball's through hole extends in a direction that
is generally perpendicular to the direction of flight 32. In this
attitude of non-standard golf ball 30, little or no air flows
through the non-standard golf ball's through-hole.
[0071] As will be appreciated, due to the continuous spinning of
non-standard golf ball 30, the two conditions that are shown in
FIGS. 3E and 3F alternate repeatedly as non-standard golf ball 30
flies through the air.
[0072] A narrowing of the non-standard sport projectile's
through-hole 28 as shown in FIG. 8C, or a flaring of through-hole
26 as shown in FIG. 8B, either restricts or enhances airflow
through through-hole 26 as the non-standard sport projectile flies
through the air after being hit. This controls the non-aerodynamic
flight of the non-standard sport projectile for desired
results.
[0073] Further, any of the through-holes 26 shown in FIGS. 8A-8C
can be partially blocked. For example, this may be accomplished by
placing an air filter within a through-hole 26, by placing an
air-flow regulator within a through hole 26, by placing debris of
some sort within a through-hole 26, or by providing a whistle
within a through-hole 26. Generally, through-hole 26 modified in
this manner will continue to function properly.
[0074] Moreover, instead of providing only one through-hole, a
non-standard sport projectile may include several such
through-holes whose axes are arranged in parallel. In addition,
these several through-holes may have different cross sectional
shapes, and/or these several through-holes may have axes are that
placed at an angle to each other, depending upon the flight
characteristic that is desired of a particular non-standard sport
projectile.
[0075] FIG. 5A is a side cross section view of a non-standard golf
ball 40 of type shown in FIG. 2A in which non-standard golf ball 40
includes six center-located and parallel through holes 41. FIG. 5B
is a top view of non-standard golf ball 40 in which six through
holes 41 are symmetrically arranged around the central axis 42 of
non-standard golf ball 40. As shown in these figures, central axis
42 of non-standard golf ball 40 passes through the geometric center
43 of non-standard golf ball 40.
[0076] FIG. 6A is a side cross section view of a non-standard golf
ball 44 of type shown in FIG. 2B wherein non-standard golf ball 44
includes six center-located and parallel through holes 45, in
accordance with the invention. FIG. 6B is a top view of
non-standard golf ball 44, wherein it is shown that the six through
holes 45 are symmetrically arranged around the central axis 46
non-standard golf ball 44. As shown in these figures, central axis
46 of non-standard golf ball 44 passes through the geometric center
47 of non-standard golf ball 44.
[0077] FIG. 7A is a side cross section view of a non-standard golf
ball 48 of type shown in FIG. 2C wherein non-standard golf ball 48
includes six center-located and parallel through holes 49. FIG. 7B
is a top view of non-standard golf ball 48, wherein it is shown
that the six through holes 49 are symmetrically arranged around the
central axis 50 of non-standard golf ball 48. As shown in these
figures, central axis 50 of non-standard golf ball 48 passes
through the geometric center 51 of non-standard golf ball 48.
[0078] The above-described through-hole or through-holes allow air
to flow through the non-standard sport projectile after the sport
projectile is hit, after it begins its flight, and as it spins.
This spinning movement generally creates a lifting force as the
sport projectile moves through the air. The amount of air that
flows through the sport projectile's through-hole or through-holes,
along with the non-standard sport projectile's speed of spin,
influences the flight behavior of the non-standard sport
projectile.
[0079] FIGS. 3A-3F are sequential view that show the striking and
the subsequent flight of a non-standard golf ball 30 that is
constructed and arranged consistent with the invention.
[0080] FIG. 3A shows a non-standard golf ball 30 of the present
invention as the non-standard golf ball 30 (in this case a
non-standard golf ball as shown in FIG. 2B) sits with the axis 33
of its through hole 25 pointing vertically upward as the head of
the golf club is about to strike non-standard golf ball 30. Where
the club strikes the non-standard golf ball 30 may be referred to
as a strike surface. In this position, non-standard golf ball 30 is
in its least-aerodynamic position.
[0081] FIG. 3B shows the compression of non-standard golf ball 30
as the head of the club strikes non-standard golf ball 30 on the
strike surface.
[0082] FIG. 3C shows non-standard golf ball 30 as it begins its
flight and as non-standard golf ball 30 begins to spin in a
counterclockwise direction as shown by arrow 31.
[0083] FIG. 3D shows the continued spinning 31 of non-standard golf
ball 30.
[0084] FIG. 3E shows the least-aerodynamic position of the spinning
non-standard golf ball 26 during its flight as shown by arrow 32,
wherein the axis 33 of through hole 25 is generally aligned with
flight direction 32.
[0085] FIG. 3F shows the most-aerodynamic position of the spinning
non-standard golf ball 30 during its flight 32 wherein the axis 33
of through hole 25 extends generally perpendicular to flight
direction 32.
[0086] As shown in FIGS. 3A-3F, when non-standard sport projectile
30 is struck, non-standard sport projectile rotates rapidly in a
reverse or counterclockwise direction 31 around a central axis of
rotation that includes the geometric center of non-standard sport
projectile 30, this being demonstrated by spin arrow 31. Rotation
31 creates a periodic high airflow through the through hole 25 that
is located generally at the center of non-standard sport projectile
30, as the projectile's through hole 25 moves into an out of
alignment position with the projectile's direction of flight
32.
[0087] However, because through hole 25 is moving away from club
head 31 at a high rate of speed, rotation 31 of non-standard sport
projectile 30 also creates a braking effect, as the outer surface
of non-standard sport projectile 30 and the sides of through hole
25 create a resistance-to-flight force, thereby reducing the
distance that non-standard sport projectile 30 will travel as a
result of club head 31 striking non-standard sport projectile
30.
[0088] More simply stated, as a spinning non-standard sport
projectile constructed and arranged in accordance with the
invention flies away from a point of impact with the club's head,
movement of the non-standard sport projectile is slowed during the
less-aerodynamic portion of the sport projectile's rotation shown
in FIG. 3E. Because a non-standard sport projectile, in accordance
with the invention, experiences generally equal parts airflow
through its through hole (see FIG. 3E) and airflow restriction
through its through hole (see FIG. 3F), the non-standard sport
projectile generates a turbine-like whirring sound when it flies
through the air, as airflow through through-hole 25 repeatedly
stops and starts at a relatively high rate of speed or
frequency.
[0089] As mentioned above, the body of a non-standard sport
projectile, in accordance with the invention, is sufficiently
strong to prevent breakage of the non-standard sport projectile
upon impact, and the body of the non-standard sport projectile has
sufficient elasticity to provide hoop strength and rebound after
striking. Thus, for a non-standard golf ball in accordance with the
invention, the body is typically formed of a high strength polymer
material, non-limiting examples of which are high density
polyethylene, polyester elastomers, urethane, acetyls, and
thermoplastic elastomers. Further, the inner core of non-standard
sport projectiles, in accordance with the invention, can be formed
of thin gauge tubular spring steel or high modulus polymer, with
the non-standard sport projectile having a soft polymer outer
coating.
[0090] FIG. 9A is a cross section view of a non-standard golf ball
55 of the type shown in FIG. 2A wherein non-standard golf ball 55
includes a circular-cylinder insert 56 that is made of spring steel
or of a high flexural modulus polymer, the axis 57 of insert 56
being coincident with the axis of the non-standard golf ball's
through hole 58.
[0091] FIG. 9B is a cross section view of a non-standard golf ball
59 of the type shown in FIG. 2B wherein non-standard golf ball 59
includes a circular-cylinder insert 60 that is made of spring steel
or of a high flexural modulus polymer, the axis 61 of insert being
coincident with the axis of the non-standard golf ball's through
hole 62.
[0092] FIG. 9C is a cross section view of a non-standard golf ball
63 of the type shown in FIG. 2C wherein non-standard golf ball 63
includes a circular-cylinder insert 64 that is made of spring steel
or of a high flexural modulus polymer, the axis of this insert
being coincident with the axis 65 of the non-standard golf ball's
through hole 66.
[0093] For a non-standard football, in accordance with the
invention, the football's body is typically formed of a soft
leather or leather-like material. For a non-standard baseball, in
accordance with the invention, the baseball's body is typically
formed of a material having characteristics that lie somewhere
between the characteristic of a material that is used to make a
non-standard golf ball and the characteristics of a material that
is use to make a non-standard football.
[0094] The size of a non-standard sport projectile, in accordance
with the invention, can be similar to the size of a corresponding
standard sport projectile, but this size relationship is not
required. That is, non-standard sport projectiles, of the
invention, are usually of a size that is similar to a standard golf
ball, a standard football, a standard soccer ball, a standard
baseball, etc. However, larger or smaller non-standard sport
projectile sizes can be provided, in accordance with the
invention.
[0095] In particular, and when considering different types of golf
club swings, larger size non-standard golf balls that
satisfactorily mate with conventional golf club heads may be
appropriate for use by beginning golfers, whereas smaller size
non-standard golf balls that are more difficult to strike properly
may be appropriate for use by expert golfers.
[0096] During use, as is shown in FIG. 4A, a non-standard golf ball
sport projectile 40, in accordance with the invention, may be
placed on the ground, or as shown in FIG. 4B the non-standard golf
ball 40 may be on a golf tee 41, so that the central axis 35 of the
non-standard golf ball's annular through hole extends generally
upward or vertical. This places the two through-hole openings on
the top and on the bottom of non-standard golf ball 40. In other
words, its through hole sits upright. Note that in some instances
an especially flared golf tee 41 may be desirable due to presence
of the through-hole that may make it inconvenient to use a
conventional small-top tee 41 because of the tendency of the
non-standard ball to fall to the ground. An alternative hitting
surface will be explained below with respect to FIG. 10. With
reference to FIG. 4B, which shows a non-standard golf ball 40
sitting on a tee, in the case of a football-type non-standard sport
projectile, the football's linear through hole is located generally
coincident with the football's long axis. In an example, the
football is placed on a kicking tee with its long axis and the axis
of the through-hole facing generally vertical. In the case of a
baseball-type non-standard sport projectile, the baseball's linear
through-hole extends through the geometric center of the baseball.
In an example, the baseball is placed on a hitting tee with the
axis of its through-hole facing generally vertical. In the case of
a soccer ball-type non-standard sport projectile, the soccer ball's
linear through hole extends through the geometric center of the
soccer ball. In an example, and the soccer ball is placed on the
ground with the axis of its through hole facing generally
vertical.
[0097] As shown in FIGS. 3A-D, a golf club head having a positive
loft produces a reverse or counterclockwise spin of non-standard
golf ball 40 when the head of the golf club strikes non-standard
golf ball 40, and when non-standard golf ball 40 subsequently
leaves club head 31. This spin is created by the positive loft of
the head, by friction that exists at impact with non-standard golf
ball 40, and by deformation of non-standard golf ball 40 as is
shown in FIG. 3B. Further, upon initial impact by head 31,
non-standard golf ball 40 is in its least aerodynamic orientation.
The vertical position of the axis 35 of the though-hole at club
head impact provides the "feel" of a standard golf ball due to the
non-aerodynamic resistance that is provided by nonstandard golf
ball 40, which in turn adds a component of force to the club's head
31.
[0098] When a non-standard sport projectile, is in this through
hole axis upright position, the leading surface of the sport
projectile, whether an aerodynamic surface or a flattened surface,
facilitates a spin of the non-standard sport projectile. The rate
of spin of the non-standard sport projectile is reduced as the
non-standard sport projectile becomes less aerodynamic as its
through-hole begins to take-in air.
[0099] As rotation of the non-standard sport projectile continues,
air no longer flows through the through-hole, and air now hits the
outside surface of the non-standard sport projectile, thus creating
a braking or slowing force to the non-standard projectile's flight
or horizontal motion.
[0100] Airflow into the non-standard projectile's through-hole
first acts as a brake, and when air no longer flows through the
though-hole, air flowing over the non-standard sport projectile
acts as an aerodynamic lift or boost. Thus, airflow through the
through-hole creates a slowing/braking force for the non-standard
sport projectile. Therefore, the non-standard sport projectile is
alternately aerodynamic and then non-aerodynamic during its
rotation and its flight. Thus, a whirring sound, somewhat like a
turbine reversing, may be caused when the non-standard sport
projectile is struck by an object such as golf club and then flies
through the air.
[0101] As a result, flight of the non-standard sport projectile is
shortened, but the non-standard sport projectile mimics the feel
and flight path of a standard sport projectile. That is, using a
non-standard sport projectile, in accordance with the invention,
such a non-standard golf ball, is satisfying to the golfer. The
flight provided by non-standard sport projectiles are suitable for
practicing the art of golf ball hitting, or the art of striking any
standard sport projectile use requires a large geographic area,
such as, for example, kicking a football to practice field goals,
or hitting a baseball. A non-standard sport projectile may be
struck without requiring the use of a net or the like within
neighborhoods and parks. Further, similar to a standard golf ball,
a non-standard golf ball will slice when the club's head is open at
impact, and it will draw when the club's head is closed at impact.
However, because a non-standard sport projectile provides a reduce
flight distance, retrieval time is reduced and retrieval is less
tedious. One of ordinary skill in the art will recognize that the
non-standard golf ball can be designed to increase or decrease the
ability to fade or draw. In particular, if one or more ribs or
ridges, similar to a gear shaped cross-section, are place in the
through-hole or on the external surface, the non-standard golf ball
can be designed to fade or draw. Further, altering the shape of the
non-standard ball, such that the shape is more oval instead of
cylindrical, may also alter the fade or draw of the non-standard
ball.
[0102] Referring specifically to non-standard sport projectiles of
the golf ball type, for simplicity, the weight of a non-standard
golf ball is usually only a fraction of the weight of a standard
golf ball. The weight of a non-standard golf ball is a function of
the physical size of the non-standard golf ball and of the type of
material used in its construction. In general, the heavier the
non-standard sport projectile, the greater the inertia of the
non-standard sport projectile that must be overcome on impact.
However, the configuration of the non-standard sport projectile's
through-hole, and the proportion of the through-hole relative to
the overall height and diameter of the non-standard sport
projectile are also important when enhancing or restricting flight
of the non-standard sport projectile. Because a non-standard golf
ball is intended for use in practicing various golf swings, such a
non-standard golf ball is effective through a wide range of
projectile weights.
[0103] A USGA conforming standard golf ball weighs 1.6 ounces. A
non-standard golf ball of the present invention can also have a
weight of 1.6 ounces. However, the weight of a non-standard golf
ball of the invention is usually less due to the presence of the
above-described through hole. Thus, a non-standard golf ball, in
accordance with the invention, is usually significantly lighter
than a standard golf ball.
[0104] Because the golf club's "feel" at impact is important when
learning to hit a golf ball properly, a weight of at least 0.3
ounces adequately simulates the feel of a standard golf ball,
however lower weights are possible within the spirit and scope of
the invention. Moreover, generally, the flight distance of a
standard sport projectile is dependent not only on the striking
force, but it is also dependent upon a spring-back of the materials
or materials that make up the standard sport projectile, as well as
the weight of the standard sport projectile, with lower weight
standard sport projectiles generally traveling a shorter distance.
Non-standard sport projectiles, in accordance with the invention,
are non-aerodynamic for about one-half of the non-standard sport
projectile's travel or flight time, and as a result the
non-standard sport projectile travels a fraction of the distance
that a standard sport projectile, such as a golf ball, travels.
However, because a rotating non-standard sport projectile acts as
an air foil for about one-half of its flight time, the non-standard
sport projectile has an aerodynamic lift, and it replicates the
trajectory of a standard sport projectile such as a golf ball,
although the non-standard sport projectile's trajectory is
significantly shortened by the braking action that occurs during
the non-aerodynamic portion of the non-standard projectile's
rotation. Therefore, non-standard sport projectiles may be struck
in backyards, neighborhoods and parks without requiring a net. Once
again referring to a non-standard golf ball, it has been found that
a proportion or ratio of the solid outer surface of the
non-standard golf ball to the open through hole surface can be as
high as about 12 to 1 or a low as about 4 to 1. However this is a
non-limiting function of design choice.
[0105] A surface ratio that is more than 4 to 1 does not function
as well because such a larger ratio creates a smaller size
through-hole that provides less airflow. The ratio of the area of
the through-hole to the height or length of the through-hole can
vary. However, it has been found that when a non-standard golf ball
of the invention is in its upright or striking position, with the
central axis of the through-hole extending generally vertical, a
through-hole area that is about the equal to the height of the
through-hole works satisfactorily. However, this through-hole
diameter to through-hole height ratio can be much lower, for
example, up to 12 times or more. As will be appreciated, the flight
and distance of a non-standard golf ball is a function of the loft
that is provided by the golf club head and the speed at which the
golf club head strikes the non-standard golf ball.
[0106] The polymeric material from which the non-standard golf ball
is made, if it is high in flexural modulus, will rebound off of the
golf club's face much like a standard golf ball. This polymeric
material should have sufficient strength to provide hoop strength
and spring back. This spring back effect is important because the
resulting rebound action is required as the non-standard sport golf
ball leaves the club's head.
[0107] As mentioned above, a novel and unobvious hitting surface
can be constructed for the non-standard golf ball type projectile.
FIGS. 10A, 10B and 10C show an alternative hitting surface 100.
Hitting surface 100 can be made of many types of material, like
plastic, natural grass, Astroturf, or the like, but it has been
found that plastics (similar to the polymers used to make the golf
type projectile) work well. Generally, as shown in FIG. 10B,
hitting surface 100 has an incline. Placing non-standard golf ball
102 on hitting surface 100 progressively up the hitting surface
simulates a higher and higher "teeing" of the non-standard golf
ball. Because the non-standard golf ball has somewhat flattened top
and bottom surfaces (as explained above), the non-standard ball 102
will not roll down the inclined hitting surface. This hitting
surface has been found useful because it is difficult to obtain
golf tees having especially flared tee surfaces to support the
non-standard golf ball. Also, using the hitting surface allows use
of the non-standard golf balls in the backyard without causing
undue divots in the yard.
[0108] Depending upon of the non-standard sport projectile's ratio
of through hole diameter to through hole length, as well as on how
well the non-standard sport projectile is struck, the non-standard
sport projection may spin until it lands, or until it stalls and
then floats to the ground.
[0109] Referring to FIGS. 11 and 18, a non-standard golf ball 1100
generally rotates around a singular axis 1102 when struck.
Cavitation of a side wall 1104 into through-hole 1106 creates
rebound or ball speed and rotation off of the club head 1108 of a
club 1110. Unlike, standard golf balls, that may be struck in any
orientation due to relative symmetry in all directions,
non-standard golf balls with a through-hole require a specific
orientation when struck so as to facilitate rotation around an
axis. Non-standard golf balls generally do not function properly if
hit in a random orientation. Non-standard golf ball 1100 must be
oriented in an upright position each time prior to striking in
order to orient axis 1102, around which it rotates, in parallel
with a face 1112 of golf club 1100. Further, functionality of
flight in this orientation also requires that ball 1100 have some
collapsibility as well as some rebound to be effective. Ball 1100
upright orientation, when struck below an equator 1114 of a center
line must collapse into the through-hole 1106 so as to create
spring back to create a high rate of reverse spin and forward
velocity off of club face 1112.
[0110] Referring now to FIGS. 11 and 12, gall 1110, with single
through-hole 1106 (or with multiple parallel through-holes 41 (FIG.
5B) extending from top to bottom in striking position), will rise
in the air and will rotate with reverse spin around horizontal axis
1102 when struck in below equator 1114. This upright striking
position limits how rotation can occur. The asymmetrical shape
requires ball 1100 to be struck with through-hole 1106 disposed
substantially vertically, and also dictates that equator 1114 and
axis 1102 of rotation is substantially parallel to, club face 1112.
As such, the strike zone is limited to just the 360 degrees around
equator 1114 of cylindrical through-hole 1106. Unlike a regular
golf ball, ball 110 has only one equator 1114. With a regular golf
ball, an equator simply relies on positioning with respect to the
ground. A sphere without a through-hole has limitless equators
around which to rotate it does not have to be repositioned with
through-hole 1106 oriented substantially upward in order to
function properly.
[0111] Ball 1100 with single through-hole 1106 (or with multiple
parallel through-holes extending from top to bottom) will allow
side wall 1114 to collapse into hole 1106. Ball 1110 may be made of
a sufficiently resilient material so as to spring back from this
collapsed position into roughly its original shape. It is this
springing back that creates forward velocity and a high rate of
reverse spin off of club face 1112.
[0112] When in flight ball 1100 spins around axis 1102, and it
oscillates between leading travel with through-hole 1106 and side
wall 1104. Hole orientation during forward travel is a wing type
orientation and facilitates aerodynamic lift and flight. Side wall
orientation is a non-aerodynamic orientation. The high rate of
reverse spin is generally created by the cavitation of the bottom
half of ball 1100 along with the loft of golf club 1110. Spin rates
may vary, but reach 10,000 revolutions per minute.
[0113] When in flight, unless ball 1110 is gently hit creating
little spin, through-hole 1106 is undetectable to the eye. As ball
1110 spins and oscillates between the hole (i.e., air foil) and
side of the ball (i.e., air brake) a distinct noise may be made as
the flight "turns on" and "turns off" in rapid succession. The
sound is the air flow being restricted as ball 1100 rotates into
the air braking orientation. Because of this trade off between
phases of flight, ball 1100 slows to a shortened distance. Like a
regular golf ball, distance and shape of ball flight for ball 1100
are effected by forward velocity, spin rate and orientation of axis
1102. Regular golf balls, when in flight, spin around one axis.
Before ball strike, the choice of axis is unlimited. Ball 1100
spins around one axis 1102 when in flight, and before being hit the
choice of axis 1102 is limited to this particular one and must be
placed in that position before striking. It is the orientation of
this axis 1102 at impact that determines if a regular golf ball or
ball 1100 hooks, slices, draws or fades. Hook generally means a
severe right to left ball flight for a right handed golfer. Slice
generally means a severe left to right ball flight. Draw generally
means a moderate right to left ball flight. Fade generally means a
moderate left to right ball flight. These ball flights are a
function of the position of the golf club at impact. An open club
face tilts the axis, slightly open means slightly tilted, severely
open means severely tilted. A square club face at impact means an
axis that is horizontal to the ground and, as a result, causes a
straight ball flight. Ball 1100 shares these attributes with a
regular golf ball if through-hole 1106 has been positioned
perpendicular to the ground so that as it spins axis 1102 will be
parallel to the ground. Further, an axle 1116 of projectile 1100,
whether a real axle piece 1116 or whether a hypothetical axle, will
always spin parallel to the circumference of the exit and entrance
of through-hole 1106.
[0114] The singularity of axis 1102 facilitates the functionality
of axle 1116 on ball 1100. Axle 1116 may perform a several
different functions. If axle 1116 is put through parallel sidewalls
1104 and perpendicular through through-hole 1106, ball flight
characteristics may be observed more readily. When hitting ball
1100 with axle 1116 in place it is important to line axis 1102
parallel with face 1112 of golf club 1110. By doing so, one can
determine whether face 1112 of club 1110 is open closed or square
at impact. As ball 1100 is struck while axle 1116 is in this
perpendicular position, a user may observe the flight of ball 1100
and the orientation of axle 1116 as it leaves club 1110. Axle 1116
typically helps move ball 1110 more aggressively toward a slice,
hook, draw or fade bias as it flies. Axle 1116 may be viewed
tilting in one direction or the other as it flies. For a right
handed golfer, axle 1116 tilt from left to right in relationship to
the horizon when club head 1108 is open on impact. For the right
handed golfer, axle 1116 will tilt from right to left in relation
to the horizon when club head 1108 is open on impact. If a golfer
has club head 1108 square at impact, axle 1116 flies true and
parallel with the horizon.
[0115] Axle 1116 may be configured in multiple shapes and
configurations. Referring to FIGS. 14 and 14A, a simple
configuration is a straight piece of material 1400 running
perpendicular to side wall 1104 at the mid point of ball 1100, when
placed on the ground. The heavier axle 1116 or 1400, the further
ball 1100 will generally travel. This can be useful in not only
observing flight of ball 1100, but in creating games requiring
achievement of specific distances. Looking at FIGS. 16, 16A, 16B
and 16C, a more complex configuration may include a figure eight of
axle 1600 is created by looping a pliable material around the
outside of ball 1100 at the center point, with two entry or exit
points 1605 of axle 1600 on either side of ball 1100.
[0116] Balancing, or putting an actual axle 1116 in projectile 1100
is all that is required nearly balance the spin. Generally, nothing
more is required to implement these axle designs. When axle 1116 is
made from a bright, translucent or fluorescent material, the
characteristics of the flight ball 1100 are enhanced when struck at
dusk or in the dark. Looking at FIGS. 15 and 15A, there is shown a
ring 1500 having an indicator point 1505. With alignment of
indicator point 1505 with a golf club prior to striking, indicator
may be viewed by a golfer after bal 1100 is struck. Ring 1500 may
share properties of an axle, and may be constructed from bright,
translucent or fluorescent material.
[0117] An alternative embodiment to simple axle 1400 through the
middle of projectile 1100, is figure eight axle 1600 (see FIGS. 16
and 16A). A shape like an infinity sign is created as ball 1100
with axle 1600 as it flies away from the golfer. Like single axle
1400, flight characteristics are evident as the infinity shape
tilts one way or the other. Figure eight shape 1600 creates a
central balance point 1605 as well as alignment points 1610 outside
of projectile 1100. This helps to create additional perimeter
weighting, which helps to facilitate the high spin rate.
[0118] Looking now at FIG. 20, there is shown a non-standard golf
ball 2000 having cushioned ends 2002. An interface 2004 between an
outside portion 2006 of ball 2000 and through-hole 2008 may create
a sharp end. In some instances, people may be present adjacent a
target or may otherwise contact non-standard golf ball 2000. As
such, cushioned ends 2002 may decrease the risk of injuring to
people. A liner 2010 may be disposed on non-standard golf ball
2000. Liner 2010 may wrap around both of the ends to form cushioned
ends 2002. Liner 2010 may be configured as a removable component or
may be configured as a non-removable applied component.
[0119] When teeing ball 1100, a tee 2100 may be used. Tee 2100
keeps ball 1100 in an upright position. A regular golf ball may be
placed with the bottom of the ball on top of a tee 2100. As such,
the placement of the bottom of the ball is of course random. Ball
1100 has hole 1106 in the bottom of ball 1100. The size of this
hole 1106 is sufficiently big to allow a conventional wooden golf
tee to go through such hole 1106. Therefore, a special tee which
supports ball 1100 at the bottom without going through this hole is
required. This can be accomplished by using a tee that will bridge
the gap of through-hole 1106, or by using a sponge type material to
elevate the ball while allowing the ball with through-hole 1106 to
be struck before striking tee.
[0120] When ball is teed up, it is usually teed up to accommodate
the larger drivers which require ball 1100 to be elevated in order
to hit it below the center line. When teeing ball 1100, it may be
teed in a straight up configuration or, for maximum distance, it
may be tilted with through-hole 1106 also tilted slightly forward
on tee 2100. The loft of a driver 2105 is relatively small (within
10 degrees of perpendicular to the ground) and because hitting less
of ball 1100 at impact creates more compression, a smaller
percentage of ball 1100 creates more deformation or cavitation into
through-hole and, therefore, more springback. Higher ball velocity
off of the club head is generally achieved in this tilt forward
position. An asymmetrical shape, like ball 1100, may have
through-hole 1106 tilted forward on impact. A round ball or other
symmetrical shapes without a singular through-hole can not induce
such a forward tilt orientation. This forward tilting motion is
unique to a ball in that it has a single through-hole, or multiple
parallel through-holes, which create a place for the side wall to
cavitate. This single point loading on ball 1100 creates higher
unit loading and, therefore, greater cavitation around the lower
circumference of ball 1100. This, in turn, creates higher initial
ball speed and rotation. When practicing with a driver away from a
driving range or practice facility, it is optimal to have a ball
with limited travel. However, such a ball should travel farther
with a driver than with the other golf clubs that a golfer is
practicing with. The driver is the most difficult golf clubs to
learn how to hit well. The reduced loft of the face of the golf
club creates less reverse spin and more tendency to tilt the axis
away from the optimal horizontal position. Further, by tilting
projectile 1100 forward on this angled tee shape 2100, only the
bottom is impacted by the face of driver 2105 creating a higher
unit load and more cavitation, more rebound and more distance.
[0121] An additional feature of the cylindrical shape of ball 2100
is that as it lands on the ground it the limited potential for
forward roll. The forward roll of device 1100 with figure eight
axel 1600 on the ground is limited by the squarish corners created
by the through-hole. This non-round shape when spinning in reverse
creates a great deal of stopping friction. In fact, with an
extremely lofted golf club to create additional spin, it is not
uncommon for ball 1100 to move in reverse for a short distance,
move forward for a short distance or stop when it hits the ground
or other object. To this end, targets may be created that contain
projectile 1100. Unlike golf, where the round ball rolls and
bounces excessively, projectile 1100 will stay in the general area
where it lands.
[0122] Referring to FIG. 22, there is shown an inclined plane
targeting system 2200 with multiple scoring holes 2205, 2210, 2215,
2220, 2225 and 2230, which may be incorporated in practice or play.
In an embodiment, inclined plane targeting system may include an
inflatable flexible material having targets or scoring holes 2205,
2210, 2215, 2220, 2225 and 2230. Inflatable targeting system 2200
may be set up in very close proximity to one or more golfers for
practice and play. By adding inclined targeting, roll and travel of
ball 1100 is closely regulated. This provides an opportunity to
have practice ranges indoors or in small outdoor areas.
[0123] The limited flight of this projectile 1100, along with the
limited forward roll, allows many types of targeting systems. For
example, targeting systems may be firm and fixed in the ground or
transportable and inflatable. As such, constrained golf-like
experiences may now be created in very small areas at low cost.
[0124] Referring to FIGS. 23-25, projectile 1100 may be designed to
float using polymers that are high rebound but light-weight.
Floating projectile 1100 allows for the design of water return
systems 2300 built into targeting systems. Being in close proximity
to the target, say 40 yards, an angular design may be provided
where projectiles 1100 roll off of the surface if a hole (not
shown) is missed. This creates a self cleaning, self pick-up target
system for continuous use with no need for other costly pick up
systems or intermittent breaks in activity to pick up projectiles
1100.
[0125] Point scoring systems may be implemented to simulate play of
a typical golf hole. For example, scoring systems like the one
described below are engaging, entertaining, challenging and allow
for practice with a purpose.
[0126] Inflatable target 2200 may be used for stroke play with a
positive points as follows. In an embodiment, yellow projectiles in
addition to the more standard white projectiles may be required.
Par for the hole is determined by the player with honors. The
number of balls played determines par for the hole. A par four
means everyone plays four balls. From a single location, the
players may each play all balls at one time. Shooting from multiple
locations, shots may be alternated. As many people as desired may
play at any one time. Order may determined by highest score, which
in this game is the better score. Highest score goes first. Points
are accrued as follows. Red hole 2205, which is furthest away and
the smallest hole, is 5 points. Orange hole 2210, second furthest
and the next smallest hole, is 3 points. Yellow hole 2215, third
furthest and the next smallest, is 1 point. Green hole 2200, fourth
furthest and the next smallest, is 0 points. White holes 2225 and
2230 are "bunkers" near high value holes 2205 and 2210. White holes
2225 and 2230 may be slightly smaller and slightly off line. White
holes 2225 and 2230 are each -2 points.
[0127] Any ball played off of the surface of inflatable 2200 is -1
point.
[0128] Each round is played with one yellow ball 1100. Yellow ball
1100 scores at a rate of twice the points, both positive and
negative points. Yellow ball 1100 may be used at any time. It is
most commonly used on the final shot, for instance as the fourth
ball on a par four.
[0129] An example of one hole of a two player game might go as
follows. Player #1 wins the coin toss and goes first. Player # 1
takes five balls 1100, four balls 1100 and a yellow ball 1100, and
announces that it is a par five. First ball is white and does not
stay on the inflatables surface. Player #1 has a score of minus
one. With two hitting surfaces, Player #2 goes next and puts his
first white ball into orange hole 2210. Player #2 has three points.
Player #1 goes next and hits a white ball into green hole 2220.
This hole 2220 is zero points. Player #1 still has a score of minus
one. Player #2 then hits a white ball into green hole 2220. Player
#2 stays at three points. Player #1 hits his third white ball into
red hole 2205. Player #1 now has a score of four points. Player #2
hits a third shot into orange hole 2210. Player #2 now has six
points. Player #1 hits a fourth white ball into yellow hole 2215
for a total of five points. Player #2 hits a fourth white ball into
yellow hole 2215 for a total score of seven points. On the final
shot, with yellow ball for a double rate of scoring, Player #1 hits
into orange hole 2210. This is worth three points multiplied by two
or six additional points. Player #1 has a final total for the hole
of eleven points. Player #2 goes next with a yellow ball and also
hits into orange hole 2210. Player #2 has a total of twelve
points.
[0130] After the first hole, Player #2 leads by one stroke and
starts the next hole by calling it out as a par three. Player #2
pulls our two white and one yellow ball, and takes the first shot
on the next hole. This scoring continues for 18 holes. The player
with the most points wins.
[0131] Match play with positive points is the objective similar to
the game above. Scoring is similar to stroke play above for each
hole. Instead of an accumulated score at the end of 18 holes, holes
are individually won and this number is tracked. This is usually a
two person competition but it can work with a larger number of
people.
[0132] Another derivative of the proposed configuration is keeping
the score like baseball. Baseball is played by keeping track of
where balls 1100 land on inflatable 2200. Red hole 2205 is home
run. Orange hole 2210 is a triple. Yellow hole 2215 is a double.
Green hole 2200 is a single. White hole 2225 or 2230 is a double.
Each of inflatable 2200 is an out. Each ball 1100 on inflatable
2200, but not in any hole, is a strike.
[0133] At three outs, a player is done for the inning. Each three
strikes is an out. Like regular baseball, keep track of runs, outs
and innings. The player with the most runs wins.
[0134] These games have great appeal because of the golf-like feel
without having to leave the shot area. With an automatic water
return system, this becomes a continuous event. In addition, very
little maintenance is required for either indoor or outdoor
settings.
[0135] Inflatables 2200 and 2300 may be configured for a small
number of players or for a large number of players. This is
generally a function of the side of inflatable 2200 and 2300 and
capacity of one or more blower 2310. Blower(s) 2310 associated with
targets 2200 and water return system 2305 are activated for use not
being used targets 2200 are deflated and water return system 2305
are each turned off. This water return system could be contained as
part of the inflatable or a separate shallow irrigation like system
dug into the ground for a more permanent installation. These larger
systems could replace conventional golf driving ranges as land
becomes more and more costly. Even now, golf courses near
residential areas are under pressure to do away with the driving
range for housing opportunities.
[0136] Various features, utilities and advantages of non-standard
sport projectiles, in accordance with the invention, will be
apparent from the following description of preferred embodiments,
as illustrated in the accompanying drawing.
[0137] When actually playing golf on a golf course, a golfer use a
standard golf ball or sphere, because the roll of the standard golf
ball after the ball lands, and the roll of the standard golf ball
when putting, which are as much a part of the game of golf as is
the driving of the standard golf ball and the subsequent flight of
the ball. However, practicing a golf club swing, to thereby strike
a golf ball, and then observing the subsequent flight of the ball,
can be accomplished when using a non-standard golf ball having an
external spherical shape or non-spherical shape as is provided by
the present invention. This invention provides a new, unusual and
unobvious non-standard practice sport projectile that simulates the
"feel" and the flight of a standard sports projectile, of which a
standard golf ball is a non-limiting example. This invention
provides a non-standard sport projectile that is constructed and
arranged to "feedback" a "striking feel" to an individual that is
generally consistent to the striking of a standard sport
projectile, such as a golf club for golfing, a foot for football,
or a bat for baseball.
[0138] Non-standard sport projectiles, in accordance with this
invention, include at least one linear through hole. As this
non-standard sport projectile passes through the air, after being
hit by, for example, a golf club, the non-standard sport projectile
spins. When the above-mentioned through hole is generally aligned
with the projectile's direction of flight, air passes through the
through hole, and the aerodynamic characteristics of the
non-standard sport projectile are lessened. As a result, the
non-standard sport projectile experiences rapidly repeating
intervals of relatively high aerodynamic flight and relatively low
aerodynamic flight as the non-standard sport projectile spins.
Thus, non-standard sport projectiles, in accordance with the
invention, provide a satisfactory "feel" on impact, they mimic the
flight of a standard sport projectile, but the length of flight of
the non-standard sport projectile is considerably shorter than the
length of flight of a standard sport projectile.
