Abstract

A toy projectile that has two parts, a cup shaped inner core having a top wall, an annular wall extending from the top wall to a bead adjacent to a bottom end, and an outer covering being somewhat donut shaped with a central opening, a top end, a bottom end, a lower recess, a curved exterior surface and a chamfer adjacent to the bottom end. The inner core is received in the central opening of the outer covering such that the top wall of the inner core is continuous with the top end of the outer covering. The bottom of the projectile may be open or covered. The projectile includes geometric aspect ratios that provide the projectile with excellent flight characteristics. The ratios are: projectile outer diameter to projectile height between 4:1 to 5.2:1; projectile outer diameter to core outer diameter between 1.20:1 to 1.45 to 1; projectile height to core bead height between 2.3:1 to 3.25:1; outer covering volume to inner core volume between 2.4:1 to 5.8:1; profile radius to projectile height between 0.5:1 to 0.8:1; and chamfer height to chamfer width between 2:1 to 6.1.

Dependent claims

A toy projectile comprising:

a circular outer covering formed of a first soft foam material, the outer covering including a central opening defined by an annular wall, an annular recess in the annular wall, a top end, a flat bottom end, a curved radial exterior surface, and a chamfer, the annular recess extending from the bottom end in the central opening of the outer covering and the chamfer being located on the exterior surface adjacent to the bottom end;
and
a circular inner core formed of a second strong resin material, the inner core having an annular sidewall, an integral closed top wall at a top end, an open flat bottom end, and the annular sidewall extending from said bottom end to said closed top wall at the top end with an enlarged bead extending from the bottom end, said second strong resin material being robust compared to said first soft foam material;
wherein the inner core is positioned in the central opening of the outer covering and the annular wall of the outer covering and the annular sidewall of the inner core adjoin one another with the enlarged bead positioned in the annular recess.

A toy projectile comprising:

a generally toroidal shaped outer covering formed of a soft foam material with a central opening surrounded by first and second annular walls having first and second diameters, respectively, a curved exterior surface, a top end, a flat bottom end, the diameter of the first annular wall being larger than the diameter of the second annular wall and the first annular wall extending perpendicular from the bottom end and parallel to the second annular wall;
and
a circular inner core formed of a strong resin material, the inner core having an integral closed top end at a top end wall, a flat bottom end, an annular sidewall extending perpendicular from the bottom end, and the annular sidewall extending from said bottom end to said closed top end with an enlarged bead extending from the bottom end, said second strong resin material being robust compared to said first soft foam material;
wherein the inner core is positioned in the central opening of the outer covering, the top end wall closes the central opening, the inner core annular side wall adjoins the outer covering second annular wall, and the inner core enlarged bead extends between the first annular wall of the outer covering and the annular side wall of the inner core.
