Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] The present application claims the benefit of U.S.
Provisional Application Ser. No. 60/906,672 filed Mar. 12, 2008 and
entitled Disk Launching Apparatus and Methods, the disclosure of
which is incorporated herein by reference in its entirety.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present inventions relate to projectile launchers and,
more particularly, to projectile launchers that permit the
resetting and re-launching of a rotating projectile after an
initial launch.
[0004] 2. Description of the Related Art
[0005] Flying toys tend to be popular with many children and
adults. These toys may use a launcher to confer motion or other
energy to permit a projectile to be launched into flight. After
launch, the projectile may be reset and re-launched from the
launcher. Typically, the resetting of a projectile involves the
orienting and engaging of various mechanical components by the
user. This can be difficult for certain users and may detract from
the playability of the toy. Therefore, a need exists for apparatus
and methods that provide for a simple mechanism for resetting a
projectile for re-launch from a launcher.
[0006] Packaging of products frequently plays an important role in
the marketing of products in the retail environment. For certain
classes of products, the packaging and presentation of the product
and its operation can substantially affect the sales volume of that
product.
[0007] A wide range of products are sold in retail outlets which
are designed to launch projectiles. These products range from tools
to sporting goods and toys. Prior packaging systems for products
have permitted the limited demonstration of products while in the
packaging. These packaging systems have typically allowed potential
purchasers to visualize lights and motion, feel vibrations, and/or
hear the sounds produced by the packaged product. These types of
packaging systems have seen substantial commercial success.
[0008] Prior systems have however typically required that the
components of the product remain secured or connected to one
another by or within the packaging. The prior packaging systems
have typically not permitted potential purchaser to actuate and
view the launching of a projectile from the packaged product and to
observe the motion of the projectile free of the launching device.
A number of problems including defining internal spaces for the
flight or movement of the projectile after it is launched and
released from a launching apparatus, the resetting of the
projectile in the launcher to facilitate the demonstration of
action to a subsequent potential purchaser, assuring the launched
projectile will not exit the packaging, among others, are faced by
the manufactures and/or packagers of such products. Accordingly,
needs exist for apparatus and methods for packaging products
designed to launch projectiles which can permit their demonstration
to potential retail purchasers.
[0009] A class of projectiles that has proven marketable in the toy
market is the flying propellers and flying discs. These are
typically launched from hand held or free standing launchers.
Frequently, the launcher cooperates with the flying disc or flying
propeller such that the flying disc or flying propeller must be
secured by hand to the mechanism of the launcher. This can reduce
the fun factor and prohibit the ability for the manufacturer to
utilize in packaging demonstration. Therefore, a need exists for
apparatus and methods for efficiently resetting a flying disc or
flying propeller that permits the automatic resetting of the flying
disc or flying propeller upon its receipt in the launcher.
[0010] Toys for launching the flying propellers and flying discs
have typically required the user to manually position the disc on
the launching mechanism to launch the disc. Many prior systems
required the precise positioning and/or orienting of the flying
propellers and flying discs to engage the launcher. The time and
effort required to position the flying propellers and flying discs
can detract from the enjoyment of the user. Therefore, a need
exists for a launching mechanism that permits the quick and easy
engagement of the flying propellers and flying discs with the
launcher.
[0011] Some toys for launching flying propellers and flying discs
are designed to both launch the flying propellers and flying discs
and to catch them as they come back down. These devices typically
include a catch mechanism. After landing, many prior launch systems
still require the precise positioning and/or orienting of the
flying propellers and flying discs to engage the launcher. This
results in added time and effort to position the flying propellers
and flying discs which can detract from the enjoyment of the user.
Therefore, a need exists for an "auto loading" system that
consistently operably positions a flying propellers and flying
discs in a launcher.

DETAILED DESCRIPTION OF THE INVENTIONS
[0044] The present inventions provide apparatus 10 and associated
methods for launching and receiving rotating projectiles 14. The
figures generally illustrate embodiments of apparatus 10 including
at least a launcher 12 and rotating projectile 14 including aspects
of the present inventions. In certain aspects, the present
inventions provide configurations for a launcher 12 and a rotating
projectile 14 that cooperate to permit the launch of the rotating
projectile 14 by the launcher 12. In other aspects, the present
inventions may provide configurations for launcher 12 and rotating
projectile 14 that tend to juxtapose the cooperating structures of
the launcher 12 and rotating projectile. In other aspects, the
rotating projectile 14 and the launcher 12 may engage one another
solely by the force of gravity. The particular exemplary
embodiments of the apparatus 10 illustrated in the figures have
been chosen for ease of explanation and understanding of various
aspects of the present inventions. These illustrated embodiments
are not meant to limit the scope of coverage but instead to assist
in understanding the context of the language used in this
specification and the appended claims. Accordingly, variations of
apparatus 10 which are different from the illustrated embodiments
may be encompassed by the appended claims.
[0045] Apparatus 10 are generally configured to launch a rotating
projectile 14 from a launch surface 42 of the launcher 12. At least
a portion of the rotating projectile 14 is configured to generate
lift when rotated about a central axis 100. After an initial
launch, the rotating projectile 14 may be placed, landed or
otherwise positioned on the launch surface 42 of the launcher 12.
The launcher 12 is configured to receive the rotating projectile 14
on the launch surface 42 and cooperate with the rotating projectile
14 to juxtapose and engage a spindle 22 and a spindle receptacle 24
for subsequent launching. In certain aspects, the launcher 12 may
be configured to launch a rotating projectile 14 within a flight
chamber 40 defined at least in part by packaging 20 encasing at
least a portion of the launcher 12.
[0046] As shown throughout the Figures, the launcher 12 is
generally configured to impart a rotational motion to the rotating
projectile 14 about a central axis 100. The launcher 12 is further
configured to receive a launched rotating projectile 14 on a launch
surface 42 and to reset the rotating projectile 14 on a spindle 22
for subsequent launching. The launcher 12 may have a variety of
configurations but is typically be configured as handheld or free
standing. When the launcher 12 is configured to be handheld, the
launcher housing 32 may define a handle 72. The launcher 12
includes a launcher housing 32 to secured various components and
define various structures of the launcher 12. The launcher housing
32 may be a single component or may include a multiple
subcomponents secured to one another.
[0047] The launcher housing 32 may secure or mount one or more of
shafts, gears, wheels, motors, valves, tubes, pumps, actuators,
batteries, reservoirs, electronics, actuators among other
components for charging, powering, driving, launching and/or
releasing the rotating projectile 14. Among the other components,
the launcher housing 32 typically secures a motor 36 or other
components configured to confer a rotational motion to a rotating
projectile 14. The launcher housing 32 also secures the motor 36 or
other mechanism connected to the spindle 22 or spindle receptacle
24 to impart rotational movement relative to the launcher housing
32 on the rotating projectile 14. Depending upon the particular
configuration, a spindle 22 or a spindle receptacle 24 may be
operably connected to the motor 36 to confer rotation upon a
rotating projectile 14. In another configuration, the rotational
movement may be otherwise generated such as, for example, with a
pull string attached to and wound around an internal spool
rotatably secured within the launcher housing 32.
[0048] The launch surface 42 is generally sized to receive the
width or diameter of the rotating projectile 14. The launch surface
42 may be a continuous flat surface, may be formed as a
discontinuous flat surface or may be a plurality of components
which cooperate to form a planar surface. The launcher housing 32
also defines a peripheral wall 52. The peripheral wall 52 extends
around at least a portion of the launch surface 42. The peripheral
wall may be perpendicular to the launch surface 42 or may form an
obtuse angle 102 with the launch surface 42. Typically, the angle
102 is between 90 degrees and 120 degrees. The peripheral wall 52
is configured to position the rotating projectile 14 on the launch
surface 42 of the launcher housing 32. Typically, the spindle 22 or
a spindle receptacle 24 is positioned to rotate about an axis 100
and may be positioned at the center of the launch surface 42. In
certain aspects, the center of the launch surface 42 may be defined
as the geometric center of the launch surface 42. In other aspects,
the center may be defined as a position equidistant from at least
three points about the peripheral wall 52. The relative proportions
and positioning of the rotating projectile 14, spindle 22, launch
surface 42, and peripheral wall 52 are configured to juxtapose the
spindle receptacle 24 and the spindle 22 when the rotating
projectile 14 is received on the launch surface 42. The spindle 22
is configured to be rotatably and/or slidably received within the
spindle receptacle 24 and to engage one or more of the retention
members 82 within the receptacle 24. A guide 62 may also be secure
to or integral with the launcher housing 32. The launch surface 42
may cooperate with a guide 62 to assist in the recapture of a
rotating projectile 14 and/or to direct a rotating projectile 14 to
the launch surface 42. The guide 62 may be formed as a flange, a
lip, webbing, netting, an enlarged opening, otherwise as will be
recognized by those skilled in the art upon review of the present
disclosure or may be formed from a combination of such
elements.
[0049] When the spindle 22 is configured to extend from the
launcher 12, the spindle 22 typically extends upward from the
launch surface 42 to receive the spindle receptacle 24 of the
rotating projectile 14. A longitudinal axis of the spindle 22, may
be substantially perpendicular to the plane defined by the launch
surface 42. Typically, the spindle 22 will rotate about its
longitudinal axis which may correspond with the axis of rotation
100 of the rotating projectile 14 when the spindle 22 is engaged
with a spindle receptacle 24 of the rotating projectile 14.
[0050] Similarly when the spindle receptacle 24 is integrated into
the launcher 12, at least a portion of the spindle receptacle 24
extends below the launch surface 42 to receive the spindle 22. In
certain aspects, an upper lip of the spindle receptacle may be
substantially coplanar with the launch surface 42. In other
aspects, the upper lip of the spindle receptacle may be below the
launch surface 42. The longitudinal axis of the spindle receptacle
24 may be substantially perpendicular to the plane defined by the
launch surface 42. Typically, the spindle receptacle 24 will rotate
about its longitudinal axis which may correspond with the axis of
rotation 100 of the rotating projectile 14.
[0051] The peripheral wall 52 is generally configured to juxtapose
the spindle 22 and the spindle receptacle 24 when a rotating
projectile 14 is received or positioned on the launch surface 42.
The peripheral wall 52 positions the spindle 22 so that it tends to
engage with the spindle receptacle 24 under the force of gravity.
When the spindle receptacle 24 is a component of the rotating
projectile 14, the peripheral wall 52 positions the spindle
receptacle 24 over the spindle 22 which extends upward from the
launch surface 42 of the launcher 12. Once positioned over the
spindle 22, the spindle receptacle 24 typically configured to
receive the spindle 22 under the force of gravity. When the spindle
22 is a component of the rotating projectile 14, the peripheral
wall 52 positions the spindle 22 over the spindle receptacle 24
which may at least in part extend below the launch surface 42 of
the launcher 12. Once positioned over the spindle receptacle 24,
the spindle 22 is typically configured to be received within the
spindle receptacle 24 under the force of gravity.
[0052] With the spindle 22 received within the spindle receptacle
24, the rotating projectile 14 may be releasably interlocked with
the launcher 12. The launcher 12 is generally configured to rotate
the rotating projectile 14 and to release the rotating projectile
14 into flight once the rotating projectile 14 reaches a sufficient
and/or desired rate of rotation. An inner surface 30 of a packaging
20 secured over at least a portion of the launcher 12 may define a
flight chamber 40 extending over the launch surface 42 into which
the rotating rotating projectile 14 is launched.
[0053] As shown throughout the Figures, rotating projectiles 14 are
generally configured to generate sufficient lift when rotated to
fly for a limited period of time. Typically, the rotating
projectiles 14 will be unpowered. The rotating projectiles 14
typically include at least one lift generating surface 44. The lift
generating surface 44 is configured to produce lift when it is
rotated about an axis of rotation 100. The rotating projectile 14
typically includes a hub 26 which may extend through the axis of
rotation 100. The lift generating surface 44 may generate lift for
the rotating projectile 14 and, in certain aspects, the rotating
projectile 14 may solely be a disk, blade or propeller. The
rotating projectile 14 is typically configured launched or released
from the launcher 12 into independent flight after the launcher 12
has conferred a sufficient rate of rotation for the lift generating
surface 44. In certain aspects, rotating projectiles 14 may be
configured to one or more of fly, hover and/or glide after launch
or release. In other aspects, the rotating projectile 14 may be in
a configuration that tends toward free fall as the rotation slows
after the initial climb. The rotating projectile 14 may be
configured to free fall at a limited rate by including features
that may tend to increase drag as the projectile's 14 rate of
rotation slows or the rotating projectile 14 stops rotating.
[0054] The lift generating surfaces 44 of the rotating projectile
14 may be in the form of one or more blades, rotors or propeller or
related structure radiating out from the hub 26 but may be
otherwise configured as will be recognized by those skilled in the
art upon review of the present disclosure. A ring 54 may be secured
to the distal ends of the lift generating surfaces 44. The ring 54
may extend peripherally about the hub 26 or may be secured to or
positioned about the distal ends of the list generating surfaces
44. The ring 54 may be configured to be atraumatic when the
projectile is rotating and/or may be configured to assist in the
resetting of the rotating projectile 14 on the launcher 12. The hub
26 is typically positioned at the axis of rotation 100 of the
projectile 24.
[0055] In one aspect, the rotating projectiles 14 include at least
a spindle receptacle 24 and one or more lift generating surface 44.
The spindle receptacle 24 may be formed in a hub 26 of the rotating
projectile 14. The spindle receptacle 24 is generally configured to
cooperate with the spindle 22 of the launcher 12 to permit the
spindle 22 to confer rotational motion upon the rotating projectile
14 or aspects thereof. The spindle receptacle 24 is generally
configured to be released from the spindle 22 due to one or more of
lift generated by the rotating projectile 14, deceleration of the
spindle 22, or otherwise as will be recognized by those skilled in
the art upon review of the present disclosure. The hub 26 may
define the spindle receptacle 24. The spindle receptacle 24 may be
configured as a passage through or cavity within the hub 26. The
spindle receptacle 24 is sized to receive at least a portion of the
spindle 22. The spindle receptacle 24 may include at least one
retention member 56. The retention member 56 is configured to
engage the spindle 22 as the rotating projectile 14 is accelerated
and/or rotated and to release the spindle 22 so that the rotating
projectile 22 may enter into free flight. The retention members 56
may be configured as one or more bars, protuberances, threads
and/or other configurations as will be recognized by those skilled
in the art upon review of the present disclosure. An inner surface
74 of the hub 26 defining the spindle receptacle 24 may be angled
or curved to direct the spindle 22 toward and/or onto the one or
more retention members 56.
[0056] In another aspect, the rotating projectiles 14 include at
least a spindle 22 and one or more lift generating surface 44. The
spindle 22 may extend downward from the hub 26. The spindle 22 is
generally configured to cooperate with the spindle receptacle 24 of
the launcher 12 to permit the spindle receptacle 24 to confer
rotational motion upon the rotating projectile 14 or aspects
thereof. The spindle 22 is generally configured to be released from
the spindle receptacle 24 due to one or more of lift generated by
the rotating projectile 14, deceleration of the spindle receptacle
24, or otherwise as will be recognized by those skilled in the art
upon review of the present disclosure. The spindle 22 is typically
positioned at the axis of rotation 100 of the rotating projectile
14 and may be secured to a hub 26. The spindle 22 is typically a
projection from lower surface of the rotating projectile 14. The
spindle 22 is configured to cooperate with the spindle receptacle
24 to permit the engaging and release of the rotating projectile
14. Typically, one or more aspects of the spindle 22 are configured
to be received within the spindle receptacle 24. The spindle 22 may
include one or more arms, grooves, projections, cavities or other
structures to engage the at least one retention member 56 of the
spindle receptacle 24. The spindle 22 is configured to engage the
retention member 56 as the rotating projectile 14 is accelerated
and/or rotated and to release the rotating projectile 14 into free
flight.
[0057] The launcher 12 cooperates with the rotating projectile 14
to impart rotational motion on the rotating projectile 14 to launch
the rotating projectile 14 into free flight. In certain aspects,
the rotating projectile 14 is released into free flight due to one
or more of a braking action applied to the spindle 22 or spindle
receptacle 24 and/or the lift generated by the rotating rotating
projectile 14. The braking action may be due to the friction within
the motor 36, a separate brake 46 in communication with spindle 22
or spindle receptacle 24, or may be inherent in the configuration
of the motor 36.
[0058] The packaging 20 is generally configured to be removably
secured over at least a portion of the launcher 12. The launcher 12
is typically removably secured within the packaging 20. In certain
aspects, the removal of the launcher 12 from the packaging 20 may
require the disassembly, disfigurement or destruction of the
packaging 20 to un-package the launcher 12. In other aspects, the
removal of the launcher 12 from the packaging 20 may be done
without destroying the functionality of the packaging 20 and permit
the reuse of the packaging 20. The packaging 20 is generally
configured to permit a potential purchaser to operate at least some
of the controls of the launcher 12 to permit the launch of a
rotating projectile 14 to be repeatably demonstrated. At least a
portion of the packaging 20 is translucent or otherwise configured
to permit the observation of the rotating projectile 14 within the
flight chamber 40. In one aspect, at least a portion of flight
chamber 40 is transparent to permit the observation of the rotating
projectile 14 within the flight chamber 40. The packaging 20 may at
least in part be formed from a clear polymeric material. However,
the packaging 20 may also be formed from various cellulose based
materials, metals, or other materials or combinations of materials
that will be recognized by those skilled in the art upon review of
the present disclosure. The materials and overall configuration of
the packaging 20 are generally dictated by the packaging, shipping
and display requirements for the particular launcher 12 that is
being packaged. Frequently, the packaging 20 will be molded from
one or more sheets of translucent plastic and may contain various
internal or external cardboard inserts. These inserts may be used
for ornamental, structural and/or other purposes such as providing
a surface for printing information.
[0059] The inner surface 30 of the packaging 20 at least in part
defines a flight chamber 40. The flight chamber 40 may be
configured to generally retain the rotating projectile 14 after the
launch of the rotating projectile 14 from the launcher 12. The
flight chamber 40 may generally extend upward and away from the
launcher 12 to define a space for the flight of the rotating
projectile 14 independent of the launcher 12. The flight chamber 40
may be defined as the area between flight chamber 40 and a surface
of at least a portion of the launcher 12 and have dimensions
sufficient to receive a launched rotating projectile 14. In certain
aspects, the inner surface 30 of the packaging 20 may be configured
to at least in part guide the rotating projectile 14 back to the
launch surface 42 of the launcher 12.
[0060] As particularly illustrated for exemplary purposes in FIGS.
1A to 2B embodiments of apparatus 10 in accordance with aspects of
the present inventions can include a launcher 12 and a rotating
projectile 14. FIGS. 1A and 1B illustrate a launcher housing 32
defining a handle 72 configured to be gripped by a user. FIGS. 2A
and 2B illustrate a launch housing 32 that is configured to be free
standing. As illustrated in FIGS. 2A and 2B, the apparatus 10 may
also include a packaging 20. An actuator 34 may be provided on the
launcher housing 32. The actuator 34 may operably connected to the
spindle 22 or spindle receptacle 24 to initiate rotation of the
spindle 22 or spindle receptacle 24. In certain illustrated
aspects, the actuator 34 may be mechanically or electrically
connected to the motor 36. When packaging 20 is secured to the
launcher 12, the actuator 34 is typically positioned outside of the
packaging 20 or is otherwise accessible through the packaging 20 to
permit access by a potential purchaser. As illustrated in FIG. 1B,
the actuator 34 is mechanically connected to an electrical switch
which controls a motor 36. The motor 36 may powered by a spring, by
a user, by a battery 38 or otherwise. The motor 36 typically
rotates a drive shaft which is secured to the spindle 22 or the
spindle receptacle 24. The spindle 22 or the spindle receptacle 24
is generally configured to confer rotational motion to the rotating
projectile 14. As particularly illustrated, the drive shaft
includes a spindle 22 that is configured to confer a rotational
force upon the rotating projectile 14 and to release the spinning
rotating projectile 14 into free flight. After flight within the
flight chamber 40, the flying disc may be reset within the launch
surface 42 utilizing at least in part gravitational forces.
[0061] Both of the illustrated embodiments include a spindle 22
rotatably secured within the launch housing 32. The spindles 22 are
shown secured at substantially the geometric center of the launch
surface 42. A motor 36 including a drive shaft secured to the
spindle may be positioned coaxially with the spindles 22 and along
an axis 100 extending through the launcher 12. In certain aspects,
a brake 46 may be in communication with the drive shaft, motor 36
and/or spindle 22 to facilitate the deceleration of the spindle 22.
The perimeter of the launch surface 42 is bounded by a peripheral
wall 52 that extends upward from the launch surface 42. As
illustrated in FIGS. 1A and 1B, the peripheral wall 52 is angled
away from a central axis 100 as it extends upward away from the
launch surface 42. As illustrated in FIGS. 2A and 2B, the
peripheral wall 52 is shown as substantially parallel or parallel
to the central axis 100 as it extends upward away from the launch
surface 42. The peripheral wall 52 may have a uniform height or the
height may vary as the peripheral wall extends around the spindle
22. A guide 62 may extend upward from an upper portion of the
peripheral wall 52. As illustrated in FIGS. 1A and 1B, the guide 62
may be in the form of a net with an upper opening having a greater
size than the size of the peripheral wall 52. As illustrated in
FIGS. 2A and 2B, a plurality of guides 62 may be provided
circumferentially about the peripheral wall 52 and generally
configured to guide a rotating projectile 14 toward the launch
surface 42.
[0062] As shown in FIGS. 2A and 2B, the packaging 20 is secured
over at least a launch surface 42 and peripheral wall 52 of the
launcher 12. The inner surface 30 of the packaging 20 in
combination with the launch surface 42 may defines the flight
chamber 40. Aspects of the inner surface 30 may be shaped to
conform to at least part of the upper portion of the launcher 12 to
secure the packaging 20 to the launcher 12. An upper surface of the
flight chamber 40 is shown as substantially flat. In one aspect,
the substantially flat surface may permit a rotating rotating
projectile 14 to hover above the launcher 12 and may for a period
of time to be observed by a potential purchaser. As illustrated,
the guide 62 may be configured to direct the rotating projectile 14
toward the launch surface 42 of the launcher 12.
[0063] As illustrated in the Figures the rotating projectile 14 is
shown in the form of a propeller or flying disc configured to fly
when rotated at a sufficient speed. The illustrated rotating
projectiles 14 of FIGS. 1A, 2A, 3A, 4 to 4C, 7, 8 and 9 include a
spindle receptacle 24 defined by an inner surface 74 of a hub 26.
The illustrated rotating projectiles 14 of FIGS. 3B, 10A and 10B
include a spindle 22 extending downward from a hub 26. In both
generally illustrated configurations, three lift generating
surfaces 44 in the form of blades radiate outward from the hub 26.
The lift generating surfaces 44 are generally configured to
generate lift when the rotating projectile 14 is rotated. A first
end 43 of the lift generating surfaces 44 is secured to the hub 26.
The second end 45 as illustrated generally radiates outward from
the hub 26. As particularly illustrated in the figures, a ring 54
may be secured to the second end of the lift generating surfaces
44.
[0064] One or more retention members 56 are secured within the
spindle receptacle 24 to cooperate with the spindle 22. In the
illustrated embodiments of FIGS. 1A, 2A, 3A, 4 to 4C, 7, 8 and 9,
the retention members 56 are configured to communicate motion from
the spindle 22 to the rotating projectile 14. As illustrated, the
spindle 22 is generally configured to receive the retention member
56. The spindle 22 is connected to the drive shaft to transfer
rotational motion from the motor 36. More particularly, the motor
36 rotates the drive shaft which rotates the spindle 22 which
causes rotation of the rotating projectile 14 by engaging the
spindle 22 with the retention member 56 of the rotating projectile
14.
[0065] In the illustrated embodiments of FIGS. 3B, 10, 10A and 10B,
the spindle 22 is configured to communicate motion from the
retention members 56 of the spindle receptacle 24 to the rotating
projectile 14. As illustrated, the spindle 22 is secured to the hub
26 of the rotating projectile and is generally configured to engage
a retention member 56 of the spindle receptacle 24. The spindle
receptacle 24 is connected to the drive shaft to transfer
rotational motion from the motor 36. More particularly, the motor
36 rotates the drive shaft which rotates the spindle receptacle 24
which causes rotation of the rotating projectile 14 by engaging the
retention member 56 with the spindle 22 of the rotating projectile
14.
[0066] For exemplary purposes, the spindle 22 is illustrated in
FIGS. 1A to 3B, 5A to 6B, 10A and 10B with a first projecting arm
68 and a second projecting arm 70 that insert into cavity or
passage of the spindle receptacle 24 to receive the retention
member 56. In certain aspects, the rotating projectile 14 may be
held in position on the spindle 22 or the spindle receptacle 24 at
least in part by gravitational forces. In other aspects, rotating
projectile 14 may be held in position on the spindle 22 or the
spindle receptacle 24 with various mechanical elements and/or
forces such as those conferred by the rotation of the rotating
projectile 14 by the spindle 22 or the spindle receptacle 24.
[0067] As particularly illustrated in FIG. 3A, the guide 62 is
configured to direct a descending rotating projectile 14 toward the
launch surface 42 and spindle 22. The rotating projectile 14 is
configured to be received on or over the launch surface 42
surrounded at least in part by the peripheral wall 52. The width or
diameter (L1+L2+L1) of the rotating projectile 14 is less than the
width or diameter (L4) defined by the peripheral wall 52 so that
the rotating projectile 14 may be rotated when the spindle 22 is
received within the cavity or passage of the spindle receptacle 24.
The spindle 22, the launch surface 42, the peripheral wall 52, and
the rotating projectile 14 are relatively configured such that when
a peripheral aspect of rotating projectile 14 is positioned against
at least a portion of the launch surface 42 and the peripheral wall
52 the relative sizing and spacing tends to juxtapose the spindle
receptacle 24 over at least an upper surface 92 of the spindle 22
such that the spindle 22 will tend to be received within the
spindle receptacle 24 under the force of gravity. Accordingly, the
diameter or width (L2) of at least a portion of the spindle
receptacle 24 is wider than the outside diameter (L5) of at least
the portion of the spindle 22 to permit at least that portion of
the spindle 22 to be received within the spindle receptacle 24. In
one aspect, when a peripheral edge of a rotating projectile 14,
such as a second end 45 of a lift generating surfaces 44 or a ring
54, contacts the launch surface 42 and peripheral wall 52, the far
wall 94 of the spindle receptacle 24 which is positioned a length
(L1+L2) from the peripheral edge extends beyond an upper surface 92
of the spindle 22. In another aspect, when a peripheral edge of a
rotating projectile 14 such as a second end 45 of a lift generating
surfaces 44 or a ring 54 contacts the launch surface 42 and
peripheral wall 52, the far wall 94 of the spindle receptacle 24
which is positioned a length (L1+L2) from the peripheral edge
extends over an upper portion 92 of the spindle 22. In yet another
aspect, when a peripheral edge of a rotating projectile 14 such as
a second end 45 of a lift generating surfaces 44 or a ring 54
contacts the launch surface 42 and peripheral wall 52, the far wall
94 of the spindle receptacle 24 which is positioned a length
(L1+L2) from the peripheral edge extends at least to an aspect of
the upper portion 92 of the spindle 22. As used herein, the far
wall 94 is generally the portion of the inner hub wall 74 which is
furthest from the point where the peripheral edge of the rotating
projectile 14 contacts the peripheral wall 52. Utilizing
gravitational forces, such sizing can permit the automatic
resetting of the rotating projectile 14 on the spindle 22.
[0068] As particularly illustrated in FIG. 3B, the guide 62 is
configured to direct a descending rotating projectile 14 toward the
launch surface 42 and spindle receptacle 24. The rotating
projectile 14 is configured to be received on or over the launch
surface 42 surrounded at least in part by the peripheral wall 52.
The width or diameter (L1+L5+L1) of the rotating projectile 14 is
less than the width or diameter (L4) defined by the peripheral wall
52 so that the rotating projectile 14 may be rotated when the
spindle 22 is received within the cavity or passage of the spindle
receptacle 24. The spindle receptacle 24, the launch surface 42,
the peripheral wall 52, and the rotating projectile 14 are
relatively configured such that when a peripheral aspect of
rotating projectile 14 is positioned against at least a portion of
the launch surface 42 and the peripheral wall 52 the relative
sizing and spacing tends to juxtapose at least a lower surface 102
of the spindle 22 over the spindle receptacle 24 such that the
spindle 22 will tend to be received within the spindle receptacle
24 under the force of gravity. Accordingly, the diameter or width
(L2) of at least a portion of the spindle receptacle 24 is wider
than the outside diameter (L5) of at least the portion of the
spindle 22 to permit at least that portion of the spindle 22 to be
received within the spindle receptacle 24. In one aspect, when a
peripheral edge of a rotating projectile 14, such as a second end
45 of a lift generating surfaces 44 or a ring 54, contacts the
launch surface 42 and peripheral wall 52, the far wall 94 (shown in
phantom) of the spindle receptacle 24 which is positioned a length
(L2+L3) from the peripheral wall 52 extends beyond an lower surface
102 of the spindle 22. In another aspect, when a peripheral edge of
a rotating projectile 14 such as a second end 45 of a lift
generating surfaces 44 or a ring 54 contacts the launch surface 42
and peripheral wall 52, the far wall 94 (shown in phantom) of the
spindle receptacle 24 which is positioned a length (L2+L3) from the
peripheral wall 52 extends under a lower portion 102 of the spindle
22. In yet another aspect, when a peripheral edge of a rotating
projectile 14 such as a second end 45 of a lift generating surfaces
44 or a ring 54 contacts the launch surface 42 and peripheral wall
52, the far wall 94 (shown in phantom) of the spindle receptacle 24
which is positioned a length (L2+L3) from the peripheral wall 52
extends at least up to an aspect of the lower portion 102 of the
spindle 22. As used herein, the far wall 94 generally the portion
of the wall 74 defining the cavity or passage of the spindle
receptacle 24 which is furthest from the point where the peripheral
edge of the rotating projectile 14 contacts the peripheral wall 52.
Utilizing gravitational forces, such sizing can permit the
automatic resetting of the rotating projectile 14 on the spindle
22.
[0069] Various configurations for hubs 24 are illustrated in FIGS.
4A to 4C. The illustrated hubs 24 generally include a passage 64
defined by an inner hub wall 74 and a retention member 56 extending
across at least a portion of the passage 64. In one aspect, the
inner hub walls 74 may be substantially parallel to the axis 100.
In other aspects, the inner hub walls 74 may be angled inward or
curved as they extend toward the center of the thickness of the
rotating projectile 14 as illustrated in FIGS. 4B and 4C. The
inwardly angled or curved inner hub walls 74 can increase the width
L2 at least a portion of the passage or cavity of the spindle
receptacle 24. The inwardly angled or curved inner hub walls 74 may
increase the probability of the spindle receptacle 24 being
positioned over an upper portion 92 of the spindle 22 to reset the
rotating projectile 14 on the spindle 22 after it is received on
the launch surface 42. In addition, FIG. 4B illustrates an
embodiment having two retention members 56 extending across only a
portion of the passage or cavity of the spindle receptacle 24.
[0070] Various configurations for spindles 22 are illustrated in
FIGS. 5A to 6B. The illustrated spindles 22 generally include a
first projecting arm 68 and a second projecting arm 70. The first
projecting arm 68 and the second projecting arm 70 are generally
configured to secure a retention member in at least a portion of
the space 65 defined between the first projecting arm 68 and the
second projecting arm 70 as the spindle 22 rotates the rotating
projectile 14 about the axis 100. In one aspect, a first notch 67
and a second notch 69 are defined by the first projecting arm 68
and the second projecting arm 70 to retain the retention member 56
of the rotating projectile 14 as the rotating projectile 14 is
accelerated and/or due to aerodynamic resistance to rotation of the
rotating projectile 14. A first launching surface 73 and a second
launching surface 75 may be provided on the first projecting arm 68
and the second projecting arm 70, respectively. The retention
member 56 of the rotating projectile 14 may contact one or more of
the first launching surface 73 and the second launching surface 75
as the spindle 22 decelerates to facilitate launch such as when the
brake 46 is engaged for example. The first launching surface 73 and
the second launching surface 75 may be configured to direct a
projectile upward along axis 100 as the projectile's 14 rotational
velocity exceeds that of the spindle's 22.
[0071] FIGS. 7 to 7B illustrate an additional configuration for
spindle 22 and spindle receptacle 24. As illustrated, a first
projecting arm 68, a second projecting arm 70 and a third
projecting arm 71 are provided on the spindle 22. The first
projecting arm 68, the second projecting arm 70 and the third
projecting arm 71 extend laterally from the spindle 22. As
illustrated, the upper aspect 92 of the spindle 22 is distinct from
the first projecting arm 68, the second projecting arm 70 and the
third projecting arm 71. The first projecting arm 68, the second
projecting arm 70 and the third projecting arm 71 are configured to
be received within a cavity 64 defined by the inner hub wall 74.
The retention members 56 are integrally formed peripherally about
the inner hub wall 74 to cooperate with the first projecting arm
68, the second projecting arm 70 and the third projecting arm 71 to
allow the spindle 22 to confer a rotational motion upon the
rotating projectile 14 and to release the rotating projectile 14
into free flight.
[0072] FIGS. 8 to 8B illustrate an additional configuration for
spindle 22 and spindle receptacle 24. As illustrated, a first
projecting arm 68, a second projecting arm 70 and a third
projecting arm 71 are provided on the spindle 22. The first
projecting arm 68, the second projecting arm 70 and the third
projecting arm 71 extend upward from the spindle 22 and define
upper aspects 92 of the spindle 22. The first projecting arm 68,
the second projecting arm 70 and the third projecting arm 71 are
configured to be received within the spindle receptacle 24 defined
by the inner hub wall 74. The retention members 56 are integrally
formed peripherally about the inner hub wall 74 to cooperate with
the first projecting arm 68, the second projecting arm 70 and the
third projecting arm 71 to allow the spindle 22 to confer a
rotational motion upon the rotating projectile 14 and to release
the rotating projectile 14 into free flight.
[0073] FIGS. 9 to 9A illustrate an additional configuration for
spindle 22 and spindle receptacle 24. As illustrated, the spindle
22 defines a helical screw 95 of decreasing radius as it extends
toward the upper portion 92. The helical screw 95 of the
illustrated spindle 22 configured to be received by one or more
retention members 56 in the form of threads defined by the inner
hub wall 74 which forms the spindle receptacle 24. The retention
members 56 are integrally formed peripherally about the inner hub
wall 74 to cooperate with the helical screw 95 of the spindle 22 to
allow the spindle 22 to confer a rotational motion upon the
rotating projectile 14 and to release the rotating projectile 14
into free flight.
[0074] FIGS. 10 to 10B illustrate an exemplary configuration for
spindle 22 secured to a hub 26 of a rotating projectile 14 and a
spindle receptacle 24 of a launcher 12 configured to receive it. As
illustrated, a first projecting arm 68 and a second projecting arm
70 are provided on the spindle 22. The first projecting arm 68 and
the second projecting arm 70 extend downward from the hub 26 and
define lower aspects 102 of the spindle 22. The first projecting
arm 68 and the second projecting arm 70 are configured to be
received within a spindle receptacle 24. The retention members 56
are integrally formed peripherally about the inner hub wall 74 to
cooperate with the first projecting arm 68 and the second
projecting arm 70 to allow the spindle receptacle 24 to confer a
rotational motion upon the rotating projectile 14 and to release
the rotating projectile 14 into free flight.
[0075] The foregoing discussion discloses and describes merely
exemplary embodiments of the present invention. Upon review of the
specification, one skilled in the art will readily recognize from
such discussion, and from the accompanying drawings and claims,
that various changes, modifications and variations can be made
therein without departing from the spirit and scope of the
invention as defined in the following claims.
