DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0021] Embodiments of the present invention provide an improved
flying disc toy 10 with an elastic cord 16 attached at its center,
as shown in FIG. 13. The elastic cord 16, preferably about 3 to 5
ft long, extends from an upper side of the flying disc, with a
handle or a wrist band 21 provided at the other end to allow the
user to control the flying disc toy with the cord.
[0022] The flying disc toy may be used in a variety of ways.
Tossing the disc in an outward motion will cause the disc to spin
in a circular motion. The user can use the cord to control the
flying direction or other motion of the disc. When the disc is
tossed outwardly, the elastic cord will stretch and then contracts,
causing the disc to return to the user. The user can also toss the
disc gently to create a spin in it, and then hold the spinning disc
by the cord and make it move in a variety of ways, such as swinging
left and right like a pendulum, or moving up and down like a yo-yo,
or circling overhead, or combinations of such motions, etc. The
spinning action of the disc helps to maintain the direction of the
rotational axis as it spins or flies.
[0023] A bouncing ball may be additionally provided on the
underside at the center of the flying disc toy to allow the disc to
be bounced like a ball or spun like a top on the ground. The user
can use the cord to control the disc toy as it is bounced or spun
on the ground.
[0024] Various embodiments of the present invention are described
below with reference to the drawings. In the descriptions below,
dimensions (sizes) are given for some of the embodiments, but it
should be understood that other suitable sizes may be used and the
invention is not limited to the particular sizes.
[0025] FIG. 1a is a top view of a flying disc toy according to an
embodiment of the present invention. FIG. 1b is a side
cross-sectional view of the flying disc toy along the direction
B-B' of FIG. 1a. The flying disc toy 10 has a circular shape in the
top view. In a preferred embodiment, the disc is approximately 12
to 13 inches in diameter. A circular interior portion 11 (also
referred to as the disc body for convenience) of the disc 10,
preferably about 10 to 11 inches in diameter, has a generally flat
shape. In the illustrated embodiment (see FIG. 1b), the
cross-section of the interior portion 11 has a gently raised
profile that is higher in the center, with the center portion 11a
(having a diameter of about 2.5 inches) raised more steeply. A rim
portion 13 of the disc 10, preferably about 1 inch wide, is curved
upwards and then downwards to form a rim having a height of about
0.8 to 0.9 inches.
[0026] It should be noted that the cross-sectional shape
illustrated in FIG. 1b is merely exemplary; other shapes may be
used. For example, the interior portion 11 may be planar rather
than having a raised profile; the rim portion 13 may curve
downwards from the disc body without first curving upwards;
etc.
[0027] In the disc body 11, a set of large cutouts (openings) 14
are formed as shown in FIG. 1a. Note that the cutouts are not shown
in the cross-sectional view FIG. 1b (in other words, FIG. 1b is
drawn as if there were no cutouts). The number of cutouts may be
three, five, etc. The cutouts 14 are arranged symmetrically around
the rotation axis of the disc 10, and may have any suitable shape.
Additional (smaller) cutouts may be formed and should also be
arranged symmetrically around the rotation axis.
[0028] FIG. 2 and FIG. 3 are top views of two flying disc toys 10a
and 10b according to alternative embodiments of the present
invention. The discs 10a and 10b are similar to the disc 10 shown
in FIGS. 1a and 1b, except that the cutouts 14a and 14b on the
discs 10a, 10b have different shapes than those shown in FIG. 1a.
The shapes of the cutouts 14, 14a, 14b shown in FIGS. 1a, 2 and 3
are merely exemplary and any suitable shapes can be used.
Preferably, the cutouts 14 (14a, or 14b) collectively occupy a half
or more of the area of the interior portion 11 of the disc 10 (10a,
or 10b). Providing cutouts on the disc toy changes the aerodynamics
of the disc as it is tossed and flies in the air. The cutouts may
also give the disc a desired appearance as it spins.
[0029] Referring back to FIGS. 1a and 1b, the disc body 11 may be
made of any suitable materials, preferably a rigid plastic
material. Preferably, the disc body 11 has a smooth surface.
Optionally, some parts 11c of the disc body may have a textured or
rough surface, which may enhance the aerodynamics and/or the
appearance of the disc.
[0030] The outermost part 15 of the disc 10 (a part of the rim
portion 13) may be made of a material that is softer than the
material of the disc body, such as molded foam, soft plastic or
rubber, forming a soft ring. The soft ring 15 enhances safety as
the disc is tossed. In addition, an outer ring made of rubber will
enable the disc to roll on the ground more smoothly.
[0031] In the embodiment illustrated in FIG. 1b, the soft ring 15
is secured to the rest of the disc by providing a circular groove
in the soft ring which, fits over a flange formed of the hard
plastic material. FIGS. 4-6 are cross-sectional views of
alternative embodiments of the present invention, showing
alternative structures by which the soft ring is joined to the body
of the disc. In the structure shown in FIG. 4, the same hard
plastic material that forms the disc body 11 is extended upwards at
the rim to form a sidewall 13c, and the soft ring 15c wraps around
both inside and outside of the sidewall 13c. In the structure shown
in FIG. 5, the same hard plastic material that forms the disc body
11 is curved upwardly and then downwardly to form a rim 13d, and a
thin layer of soft material is formed over the downward curving
portion of the rim to form the soft ring 15d. Preferably, the soft
ring 15d is a rubber material co-molded with the rim 13d. In the
structure shown in FIG. 6, the same hard plastic material that
forms the disc body 11 is curved upwardly and then downwardly to
form a rim 13e, where the downward curving part of the rim has a
series of holes. A ring 15e made of a soft material is provided
with a series of inward protrusions that fit into the holes along
the rim 13e to secure the ring 15e to the disc. Of course, other
structures may be employed to secure the soft ring to the rest of
the disc.
[0032] As mentioned earlier, a cord is attached at the center of
the flying disc toy to allow a user to control the disc toy. The
cord may be an elastic cord or non-elastic cord and may have any
suitable thickness (diameters) and length. The cord may be made of
any suitable materials, such as yarn, rubber, cotton, polyester,
nylon, polypropylene, etc. If an elastic cord is used, it may be a
straight cord or a curly coiled elastic twist cord.
[0033] FIGS. 7, 8 and 9 illustrates alternative structures for
attaching a cord 16 to the body of the disc. As shown in FIGS. 7-9
(see also FIGS. 1a and 1b), a hole 12 is provided on the disc body
11 at its geometric center. In one embodiment, the hole is
approximately 0.12 inches in diameter, but other sizes may also be
used, depending on the thickness of the cord. The cord 16 passes
through the hole 12, and a knot 16a is tied in the cord on the
underside of the disc 10. As mentioned earlier, the other end of
the cord 16 is provided with a handle, a wristband, or other
attachments (not shown in FIGS. 7-9) for easy handling by the
user.
[0034] In the embodiments of FIGS. 7 and 8, a bearing 17a or 17b
with a through hole is located between the knot 16a and the center
hole 12 of the disc, where the cord 16 passes through the through
hole of the bearing. The bearing may have a ball shape (FIG. 7), a
bell shape (FIG. 8), or other shapes as long as it has a smooth and
rounded top portion for contacting the disc 10. As the disc spins,
the bearing 17a/17b can rotate freely with respect to the disc.
[0035] The bearing 17a/17b preferably has a recessed portion or has
a hollow interior as shown in FIGS. 7 and 8, so that the knot 16a
is disposed within the recess or hollow interior of the bearing
17a/17b. The knot may be secured to the bearing by an adhesive
material. Having the knot contained inside the bearing gives the
disc more stability as it is tossed, and keeps the cord from
getting twisted and tangled as the disc spins.
[0036] In the embodiment of FIGS. 7 and 8, the disc body has a
small downward protrusion 12a around the center hole 12, such that
only the bottom portion of the protrusion contacts the bearing
17a/17b. This feature reduces the contact area between the bearing
and the disc body to minimize friction.
[0037] In some embodiments, the center portion 11a of the disc has
a raised profile, which provides a space under the disc for the
bearing 17a/17b. A cover 18 may be provided to enclose the bearing,
as shown in FIG. 8. In this embodiment, the cover 18 is located on
the underside of the disc 10 below the raised center portion 11a,
and has a flat bottom that is located approximately in the same
plane as the lower-most part 11b of the disc body. The cover 18 may
be snapped or glued or screwed to the body of the disc. A small
drain hole may be provided on the cover or between the cover 18 and
the body of the disc to allow any liquid or dust that entered the
enclosed space to be removed. The cover 18 serves several
functions. First, it protects the bearing by keeping dirt and
moisture away so that they do not affect the performance of the
disc toy. Second, it conceals the bearing to give the disc toy a
clean finished look. Third, it helps to keep the bearing in place
during flight when the cord is not tensioned. For example, a user
may toss the disc toy by completely letting go of the cord. In such
a case, the cord is not tensioned, and the bearing may move freely
with respect to the disc. Without the cover 18, the bearing might
move too far away from the disc body.
[0038] In the embodiment of FIG. 9, a bearing is not provided, and
the knot 16a directly contacts the disc body. A cover 18 is
provided on the underside of the disc in the center area to keep
the knot 16a enclosed in a space formed by the cover 18 and the
body of the disc.
[0039] It should be noted that in the above description, although
the cord 16 is said to be "attached" to the disc body, it is not
fixedly attached to the disc body; in fact the end of the cord can
move freely in the center hole 12, especially when the cord is not
under tension. Therefore, the meaning of the term "attached" should
be understood broadly in this context.
[0040] FIG. 10 illustrates another embodiment of the flying disc
toy 10 having a bouncing ball 19 attached to the underside of the
disc toy at the center. The ball 19 may be solid or hollow, and may
be made of any suitable materials that allow it to bounce, such as
plastic, rubber, foam, etc. It may have any suitable shape and
size. In the embodiment shown in FIG. 10, the ball 19 is a slightly
elongated half-sphere attached to the underside of the disc body,
with the round portion of the half sphere facing downwards for
bouncing. The bouncing ball 19 also functions as a cover to cover
the bearing and the knot of the cord (not shown in FIG. 10).
Alternatively, both a cover and a ball may be provided, with the
ball fitting over the cover. As another alternative, the ball may
have an internal partition located close to the disc body to serve
the function of keeping the bearing in place as discussed
earlier.
[0041] In an alternative embodiment shown in FIG. 11, a spherical
shaped bouncing ball 19a is located on the underside of the disc 10
and attached to the bearing 17c. In this embodiment, the bouncing
ball 19a is not attached to the body 11 of the disc.
[0042] The bouncing ball 19/19a allows the user to bounce the disc
toy 10 on the ground. The bouncing ball 19 of FIG. 10 also allows
the user to spin the disc like a top on the ground.
[0043] In some embodiments, as shown in FIG. 12, a series of air
holes 20 are provided along the rim portion 13 of the disc 10. In
the illustrated embodiment, the rim portion 13 has an upside-down U
shape in the cross-sectional view, and the air holes 20 are
preferably located near the top of the rim 13. When the disc 10
spins in one direction as indicated by the arrow labeled S, air can
flow upwards through the air holes 20 and laterally in an opposite
direction relative to the spin direction, as indicated by the
arrows labeled A. The airflow may help to stabilize the disc when
it is flying.
[0044] As pointed out earlier, the cutouts 14 on the disc body 11
provide desirable aerodynamic effects for the disc as it is tossed
and flies in the air. This effect is especially significant when
the disc toy is used with a bouncing ball and spins on the ground
as a top, and helps the disc toy to spin in a more balanced
manner.
[0045] In preferred embodiments of the present invention, the disc
body 11 is raised in the center in the cross-sectional view. This
may enhance the balance and stability of the disc as it is tossed
in the air. This cross-sectional shape also allows the elastic cord
to move more freely as the disc is spinning, and gives the user
more control of the disc.
[0046] As described above, the soft ring 15, the cover 18 and the
bounding ball 19 have their respective functions. In addition,
these features may contribute to achieving a desired weight
distribution to help stabilize and balance the disc toy as it
flies. The cover 18 or the bounding ball 19, or other structures,
may function as a center weight; the soft ring 15 may add weight to
the rim portion of the disc. These features, combined with other
features such as the cutouts 14 and air holes 20, can accomplish an
overall disc design that has good aerodynamic properties. Not all
of these features are required in the flying disc toy.
[0047] It will be apparent to those skilled in the art that various
modification and variations can be made in the flying disc toy of
the present invention without departing from the spirit or scope of
the invention. Thus, it is intended that the present invention
cover modifications and variations that come within the scope of
the appended claims and their equivalents.
