TECHNICAL FIELD
The subject disclosure relates to toys. More particularly, the present disclosure relates to a spinning self-propelled aquatic toy having an eccentric motor and fins for aqueous propulsion.
BACKGROUND
Various non-aqueous eccentric toys exist in the marketplace. Particularly, generally round or spherical shaped moving ball toys will move around in a random or eccentric motion on a solid surface. These toys are not designed to be submerged into water. Consequently, these toys are limited to dry conditions and are placed on the floor or other flat surfaces.

DETAILED DESCRIPTION
The subject disclosure is described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. It may be evident, however, that the present disclosure may be practiced without these specific details.
FIGS. 1 and 2 illustrate the self-propelled spinning device 10 submerged and in use in an aqueous environment. As shown, the self-propelled spinning device 10 propels in a forward direction by various fin-shaped projections 42 as it rotates. The self-propelled spinning device 10 depicts a fish like animal but can be made to resemble other animals such as but not limited to an octopus, whale, duck, and other creatures contemplated to exist.
As shown in FIGS. 3 and 4, the self-propelled spinning device 10 is comprised of a curved hollow housing 11. The hollow housing 11 has an equator 12 with a first or an upper hemisphere 30 having projections 42 formed adjacent to an area opposite the equator 12, and a second or a lower hemisphere 20 connected to the first hemisphere 30 at the equator 12.
The combination of the internal drive system 70 (discussed later), and the projections 42 operate together to drive the self-propelled spinning device 10 in a forward swimming direction, as shown in FIGS. 1-2. This forward propelled direction is opposite the location of the location of the projections 42. When the hollow housing 11 is spun in a rotating motion, the projections 42 exert a driving force on the surrounding aqueous solution thereby driving the hollow housing 11 in an opposite, forward moving direction.
As shown, the self-propelled spinning device 10 is preferably spherical in shape. However, it is to be understood that the self-propelled spinning device 10 can also be made into other shapes such as, and not limited to, oblong, elliptical, oval, and hourglass shape or other shape capable of traversing through an aqueous fluid or the like.
FIG. 5 illustrates a cross sectional view of the self-propelled spinning device 10. As shown, the drive system 70 is disposed inside the hollow housing 11 and rotatably mounted about a rotational axis (A) along an axle pin 74. Referring also to FIGS. 7 and 8, the rotational axis A runs from a concentric center 13a of the first hemisphere 30 (shown in FIG. 7) to a concentric center 13b of the second hemisphere 20 (shown in FIG. 8).
FIG. 6 shows an exploded view of the self-propelled spinning device 10 further comprising a first hemisphere 30 and second hemisphere 20 separated by a ring 60 at an equator. FIG. 6 also depicts a drive system 70, and a spherical cap 40 having projections 42. A plurality of fasteners 14 secures the first hemisphere 30 to the second hemisphere 20 at the equator 12. As shown in FIG. 6, each fastener 14 may be countersunk through a tunneled cavity 16 located on, for example, an outer surface 32 of the first hemisphere 30. The fasteners 14 may be disposed parallel to and at a distal radius from the rotational axis A. Both the ring 60 (discussed below) and a threaded slot 18 located in the lower hemisphere 20 may be adapted to receive the fastener 14. However, it is to be understood that the second hemisphere 20 and the first hemisphere 30 may be joined by any type of suitable fastener mechanism, and at any distal position from the rotational axis A known by one of ordinary skill in the art.
Referring back to FIG. 5, the ring 60 is adapted to fit securely between the first hemisphere 30 and second hemisphere 20 thereby acting as a protective seal against water or any other substance from seeping through the hollow housing 11 when in a closed position. Thus, a perimeter of the ring 60 will generally be dependent on and sized to mate with the perimeter of an outer bottom edge or rim 63 located on the first hemisphere 30 and the perimeter of the inner top edge or rim 64 located on the second hemisphere 20 respectively. For example, as shown in FIG. 6, since the first hemisphere 30 and second hemisphere 20 appear spherical having a circular rim 63, 64, the ring 60 is also circular in shape.
The ring 60 further comprises a plurality of slotted projections 62 connecting the ring 60 between the first hemisphere 30 and second hemisphere 20 as shown in FIG. 6. The slotted projection 62 further prevents any water or liquid to penetrate through the hollow housing 11 when the fastener 14 is inserted through the tunneled cavity 16 and into the threaded slot 18 of the second hemisphere 20. The ring 60 is preferably made of silicone or rubber like material such that a waterproof seal is maintained for the self-propelled spinning device 10.
FIG. 6 also illustrates a spherical cap 40 having projections 42 extend radially outwards in a generally circumferential path. The spherical cap 40 is centrally disposed above an upper portion 33 of the first hemisphere 30. The upper portion 33 is slightly recessed such that when the spherical cap 40 is attached, it is integrated flush with the first hemisphere 30. The spherical cap 40 is preferably circular but can take on other shapes adapted to fit the shape of the self-propelled spinning device 10. The spherical cap 40 is preferably made of silicone, rubber, or a TBD-like material that is flexible, resilient, and water resistant.
FIGS. 7-9 illustrate the top view, bottom view, and partial exploded view of the first hemisphere 30 separated from the second hemisphere 20. As shown in FIG. 7, the outer surface 32 of the first hemisphere 30 includes the spherical cap 40.
An integrated power button 34, located at the center 13a of the spherical cap 40, is used to turn on or off the self-propelled spinning device 10. When the power button 34 is depressed, a switch cap 38, located on an inner face 36 opposite the power button 34, makes contact with a switch 76 attached to the drive system 70 housed inside the hollow sphere 11 as shown in FIGS. 8-9. The power button 34 is integrated with the spherical cap 40 and is preferably made from, but is not limited to, the same material. The power button 34 may be activated to rotate the drive system 70 at various speeds.
Referring back to FIG. 7, the projections 42 surrounds the power button 34 located on the spherical cap 40. The projections 42 or fins have a slight curvature such that the projections are generally U-shaped or C-shaped. Thus, when the self-propelled spinning device 10 is in water, the projections 42 simultaneously guide the water to move behind the self-propelled spinning device 10 and push the self-propelled spinning device to move in a forward direction, as shown in FIGS. 1-2. The projections 42 are integrated with the spherical cap 40 and are preferably made from, but are not limited to, the same material.
FIG. 10 illustrates a partial exploded view of the second hemisphere 20 in the open position. The drive system 70 is connected via the axle pin 74 to the second hemisphere 20 as shown in the exploded rendering in FIG. 10. An axle pin 74 extending from the bottom of the drive system 70 is permanently disposed inside a projecting support member 24 having a receiving hole 26. The support member 24 is tree shaped or triangular and provides ample support for the drive system 70 when the drive system 70 spins on the axle pin 74 at axis A.
FIGS. 11-12 illustrate the top view and perspective view of the second hemisphere 20 and the drive system 70 disposed therein an open position, and FIG. 13 depicts a partial view of the internal drive system 70. The drive system 70 further comprises a DC motor 80, a power source 90, a weight 100 and a gear assembly 82.
The weight 100 is placed in an offset position from the axle pin 74 and functions as dead weight. As a result, the force of gravity pulls the weight 100 downwards causing the hollow housing 11 to spin about a rotational axis A counter to the spinning direction of the drive system 70. This motion causes the self-propelled spinning device 10 to move in an eccentric motion.
The gear assembly 82 is composed of a first driven worm gear 84 and is attached to the motor 80. Power from the first driven worm gear 84 is translated to the second driven gear 86, which in turn drives a third gear 88, which is attached to the axle pin 74. The third gear 88 drives a motor housing 81 around the axle pin 74 in an eccentric rotational motion.
FIG. 14 illustrates a partially exploded perspective view of the second hemisphere 20. As shown in FIG. 14, the power source 90 depicts a battery 91. In an open position, a battery cover 92, located on top of a battery housing 96, pivots about a fixed screw 93 when the battery cover 92 detaches from the battery housing 96. As shown in FIG. 14, the battery 91 may be replaced by unscrewing a removable screw 94 extending out from the battery cover 92 that is connected to the battery housing 96. It is to be understood that the power source 90 may take various forms according to this subject disclosure. For example, power source 90 may be embodied in the form of a rechargeable battery having an exterior outlet with a protective cover on the surface of the hollow housing 11.
