FIG. 1 a is a top view of a flying disc toy according to an embodiment of the present invention.FIG. 1 b is a side cross-sectional view of the flying disc toy along the direction B-B′ ofFIG. 1 a. Theflying 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 thedisc 10, preferably about 10 to 11 inches in diameter, has a generally flat shape. In the illustrated embodiment (seeFIG. 1 b), the cross-section of theinterior portion 11 has a gently raised profile that is higher in the center, with thecenter portion 11 a (having a diameter of about 2.5 inches) raised more steeply. Arim portion 13 of thedisc 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. - It should be noted that the cross-sectional shape illustrated in
FIG. 1 b is merely exemplary; other shapes may be used. For example, theinterior portion 11 may be planar rather than having a raised profile; therim portion 13 may curve downwards from the disc body without first curving upwards; etc. - In the
disc body 11, a set of large cutouts (openings) 14 are formed as shown inFIG. 1 a. Note that the cutouts are not shown in the cross-sectional viewFIG. 1 b (in other words,FIG. 1 b is drawn as if there were no cutouts). The number of cutouts may be three, five, etc. Thecutouts 14 are arranged symmetrically around the rotation axis of thedisc 10, and may have any suitable shape. Additional (smaller) cutouts may be formed and should also be arranged symmetrically around the rotation axis. -
FIG. 2 andFIG. 3 are top views of twoflying disc toys discs disc 10 shown inFIGS. 1 a and 1 b, except that thecutouts discs FIG. 1 a. The shapes of thecutouts FIGS. 1 a, 2 and 3 are merely exemplary and any suitable shapes can be used. Preferably, the cutouts 14 (14 a, or 14 b) collectively occupy a half or more of the area of theinterior portion 11 of the disc 10 (10 a, or 10 b). 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. - Referring back to
FIGS. 1 a and 1 b, thedisc body 11 may be made of any suitable materials, preferably a rigid plastic material. Preferably, thedisc body 11 has a smooth surface. Optionally, someparts 11 c of the disc body may have a textured or rough surface, which may enhance the aerodynamics and/or the appearance of the disc. - 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. Thesoft 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. - In the embodiment illustrated in
FIG. 1 b, thesoft 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 inFIG. 4 , the same hard plastic material that forms thedisc body 11 is extended upwards at the rim to form asidewall 13 c, and thesoft ring 15 c wraps around both inside and outside of thesidewall 13 c. In the structure shown inFIG. 5 , the same hard plastic material that forms thedisc body 11 is curved upwardly and then downwardly to form arim 13 d, and a thin layer of soft material is formed over the downward curving portion of the rim to form thesoft ring 15 d. Preferably, thesoft ring 15 d is a rubber material co-molded with therim 13 d. In the structure shown inFIG. 6 , the same hard plastic material that forms thedisc body 11 is curved upwardly and then downwardly to form arim 13 e, where the downward curving part of the rim has a series of holes. Aring 15 e made of a soft material is provided with a series of inward protrusions that fit into the holes along therim 13 e to secure thering 15 e to the disc. Of course, other structures may be employed to secure the soft ring to the rest of the disc. - 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.

FIGS. 7 , 8 and 9 illustrates alternative structures for attaching acord 16 to the body of the disc. As shown inFIGS. 7-9 (see alsoFIGS. 1 a and 1 b), ahole 12 is provided on thedisc 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. Thecord 16 passes through thehole 12, and aknot 16 a is tied in the cord on the underside of thedisc 10. As mentioned earlier, the other end of thecord 16 is provided with a handle, a wristband, or other attachments (not shown inFIGS. 7-9 ) for easy handling by the user. - In the embodiments of
FIGS. 7 and 8 , a bearing 17 a or 17 b with a through hole is located between theknot 16 a and thecenter hole 12 of the disc, where thecord 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 thedisc 10. As the disc spins, the bearing 17 a/17 b can rotate freely with respect to the disc. - The bearing 17 a/17 b preferably has a recessed portion or has a hollow interior as shown in
FIGS. 7 and 8 , so that theknot 16 a is disposed within the recess or hollow interior of the bearing 17 a/17 b. 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. - In the embodiment of
FIGS. 7 and 8 , the disc body has a smalldownward protrusion 12 a around thecenter hole 12, such that only the bottom portion of the protrusion contacts the bearing 17 a/17 b. This feature reduces the contact area between the bearing and the disc body to minimize friction. - In some embodiments, the
center portion 11 a of the disc has a raised profile, which provides a space under the disc for the bearing 17 a/17 b. Acover 18 may be provided to enclose the bearing, as shown inFIG. 8 . In this embodiment, thecover 18 is located on the underside of thedisc 10 below the raisedcenter portion 11 a, and has a flat bottom that is located approximately in the same plane as thelower-most part 11 b of the disc body. Thecover 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 thecover 18 and the body of the disc to allow any liquid or dust that entered the enclosed space to be removed. Thecover 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 thecover 18, the bearing might move too far away from the disc body. - In the embodiment of
FIG. 9 , a bearing is not provided, and theknot 16 a directly contacts the disc body. Acover 18 is provided on the underside of the disc in the center area to keep theknot 16 a enclosed in a space formed by thecover 18 and the body of the disc. - 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 thecenter hole 12, especially when the cord is not under tension. Therefore, the meaning of the term “attached” should be understood broadly in this context. -
FIG. 10 illustrates another embodiment of the flyingdisc toy 10 having a bouncingball 19 attached to the underside of the disc toy at the center. Theball 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 inFIG. 10 , theball 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 bouncingball 19 also functions as a cover to cover the bearing and the knot of the cord (not shown inFIG. 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. - In an alternative embodiment shown in
FIG. 11 , a spherical shaped bouncing ball 19 a is located on the underside of thedisc 10 and attached to thebearing 17 c. In this embodiment, the bouncing ball 19 a is not attached to thebody 11 of the disc. - The bouncing
ball 19/19 a allows the user to bounce thedisc toy 10 on the ground. The bouncingball 19 ofFIG. 10 also allows the user to spin the disc like a top on the ground. - In some embodiments, as shown in
FIG. 12 , a series ofair holes 20 are provided along therim portion 13 of thedisc 10. In the illustrated embodiment, therim 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 therim 13. When thedisc 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. - As pointed out earlier, the
cutouts 14 on thedisc 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. - 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. - As described above, the
soft ring 15, thecover 18 and the boundingball 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. Thecover 18 or the boundingball 19, or other structures, may function as a center weight; thesoft ring 15 may add weight to the rim portion of the disc. These features, combined with other features such as thecutouts 14 andair 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. - 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.
