DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(18) As best seen in FIG. 1, an exemplary embodiment of a throwing or catching toy 10 includes a first body 12 defined as having a longitudinal axis 14. A length 16 of the first body along the longitudinal axis 14 between a front end 18 of the first body to a back end 20 of the first body 12 is longer than an equatorial diameter 22 of the first body 12. A generally cylindrically-shaped annular second body 24 is disposed about the first body 12 aligned along the longitudinal axis 14. The second body 24 has a much larger outer diameter 26 as compared to the equatorial diameter 22 of the first body 12. For example, the equatorial diameter 22 can be about 5 or 4 inches or less whereas the outer diameter 24 may be at least 7, 8 or 9 inches or more. Then, a connection structure 28 (best seen in FIG. 2) is disposed and connected between the first body 12 and the second body 24 where the connection structure 28 secures the first body 12 in a fixed position relative to the second body 24.

(19) As best seen in FIGS. 1 and 7 the first body 12 may define a first center of gravity 30 along the longitudinal axis 14, and the second body 24 may define a second center of gravity 32 along the longitudinal axis 14. As in FIG. 1, the first center of gravity 30 may be located at the same place along the longitudinal axis 14 as the second center of gravity 30. Alternatively shown in FIG. 5-7, the first center of gravity 30 may be located behind the second center of gravity 32 along the longitudinal axis 14. Not shown but opposite of FIG. 7, the first center of gravity 30 may be located ahead of the second center of gravity 32 along the longitudinal axis 14. Shifting the center of gravities may be a critical aspect for getting the overall balance and overall center of gravity correct for the toy to fly in a straight and reliable direction. Furthermore, the toy 10 can include a method or structure that allows the user to adjust the center of gravities such that the flight characteristics of the toy 10 can be adjusted per each individual user.

(20) It may help the performance of the toy if the overall weight is kept very low, which is well below the weight of a leather football of similar size. Therefore, to achieve such low weights, an overall density of the first body 12 or the second body 24 may be less than 6, 5, 4, 3 or 2 pounds per cubic foot. For example, expanded polypropylene (EPP) is commonly made in densities of 1.3 lbs per cubic foot (lcf) or 1.8/1.9 lcf. Expanded polystyrene (EPS) is also an option and comes in similar densities to the EPP. Either the first or second body could be made as an EPS foam or an EPP foam. Other foams may be used as long as they have a very low density comparable to the EPS and EPP foams.

(21) The first body 12 may take many shapes such as missiles, rockets and other fantasy designs (See FIGS. 11 and 12) but is generally is shaped as a prolate spheroid, an elongated spheroid or as an American football as shown in FIGS. 1-9. To help the user distinguish between the front end 18 of the football body 12 and the back end 20, laces 34 can be integrated to help show the user where to grasp the football body 12. Laces 34 can also be integrated into the fantasy designs shown in FIGS. 11 and 12 again helping the user in utilizing the toy 10.

(22) The generally cylindrically-shaped annular second body 24 may be shaped as a ring airfoil 24 that is rotationally symmetric about the longitudinal axis 14 to facilitate spinning of the ring airfoil 24 and first body 12 when the toy 10 is thrown by a person. The ring airfoil 24 defines a circumferential leading edge 36 opposite a circumferential trailing edge 38, where the front end 28 of the first body 12 extends forward beyond the circumferential leading edge 36 of the ring airfoil 24, and where the back end 20 of the first body 12 extends backward beyond the circumferential trailing edge 38 of the ring airfoil 24. The width 48 of the ring airfoil 24 is less than the length 16 of the first body 12. For example, the width 48 may be about 2-5 inches, or even more than 5 inches, but still less than the length 16 of the first body 12.

(23) FIGS. 10A-10E are enlarged cross-sections taken from FIG. 1 where the cross-section is aligned with the longitudinal axis to best show the shape of the ring airfoil 24. As shown in FIG. 10A, a cross-section through the ring airfoil 24 may be a symmetrical shaped airfoil cross-section. Alternatively as shown in FIG. 10B the ring airfoil 24 may have a non-symmetrical shaped airfoil cross-section. FIG. 10B actually shows the outside surface 50 as being generally flat whereas the inside surface has a more pronounced curvature. This is a typical shape of a wing but upside-down. As can be understood by those skilled in the art, a wide variety of different cross-sections or wing profiles may be used for the ring airfoil 24.

(24) Alternatively shown in FIG. 10C, the ring airfoil 24 may be comprised of a thin thickness of polymer, wherein the ring airfoil has a generally convex upper surface 40 opposite a generally concave lower surface 42, where the upper and lower surfaces define the thin thickness of the ring airfoil 24. FIG. 10D shows a flat ring airfoil 24. FIG. 10E is more of a traditional shaped wing which can be made from foam, polymer or a combination thereof. It is possible to have an inner core of foam that has either one or both sides bonded to a thin sheet of polymer. Due to the toy 10 being a football, it will crash into various objects and must be design to absorb some shock loads without breaking. Alternatively, a foam airfoil ring may have a very thin adhesive sticker applied, where the adhesive sticker helps to add strength and stiffness. The sticker could be a durable and weather resistant polymer that can easily absorb stress loads in tension to increase the durability of the ring airfoil.

(25) Reducing drag of the toy 10 as it flies through the air will aid in producing longer throws. As shown in FIG. 9, to reduce drag the first body 12 may have a cylindrically shaped aperture 44 aligned through the longitudinal axis 14.

(26) The connection structure 28 may be a plurality of struts 28 symmetrically disposed about longitudinal axis 14 attaching the first and second bodies. As shown in the drawings herein, each strut 28 is rotated 90 degrees about the longitudinal axis 14 relative to the next adjacent strut 28. This means a total of four struts are used. However, it is understood that two, three, five, six or any other number of struts could be used where they are equally spaced out. For example, the spacing may be 180 degrees, 120 degrees, 60 degrees, 45 degrees and so on.

(27) The plurality of struts 28 may be rod-shaped as shown in FIGS. 5-6, 8-9 or alternatively may be substantially flat sections as shown in FIGS. 2-4, which can then also be twisted as shown in FIG. 4 as they extend radially outward to help cut through the air better when thrown spirally. If the flat sections are twisted, this means that the toy is then limited to being either right-handed or left-handed configured. This is because as the product spins, the flat struts will cut thrown the air effectively when spinning one direction, but not the other direction.

(28) Also shown in FIG. 8 is that the plurality of rods 28 are angled forward to backwards. This is done to also reduce drag as angled struts produce less drag when they cut through the air as compared to perpendicularly positioned struts.

(29) FIG. 11 shows the first body 12 as a futuristic design of a football. FIG. 12 takes the concept even further by styling the first body 12 as a missile. Then a football shaped rear portion 46 is curved and mimics a traditional football body, as this helps the user to understand where to grip and throw the toy 10.

(30) Overall, a person can throw and catch the first body 12 similar to how a traditional American football is thrown and caught by throwing and spinning both the first and second bodies as one assembly. The overall toy 10 makes for an interesting and exciting new play pattern that adds a new dimension of fun to the game of catch.

(31) To help the flight trajectory of the toy 10, the overall weight must be kept low and below one pound, which is about to 453 grams. In other embodiments, the overall weight of the toy 10 can be below 350 grams, 300 grams, 250 grams, 200 grams or even below 150 grams. A lighter overall toy 10 would stay aloft in the air longer as less force by gravity is pulling it downwards.

(32) Although several embodiments have been described in detail for purposes of illustration, various modifications may be made to each without departing from the scope and spirit of the invention. Accordingly, the invention is not to be limited, except as by the appended claims.
