DETAILED DESCRIPTION
[0060] In this Specification, claims, and accompanying drawings, reference is made to the particular features of the invention. It is to be understood that the disclosure of the invention includes all possible combinations of such particular features. For example, where a particular feature is disclosed in the context of a particular aspect or embodiment of the invention, or a particular claim, that feature can also be used, to the extent possible, in combination with and/or in the context of other particular aspects and embodiments of the invention, and the invention generally.
[0061] FIG. 2 illustrates one embodiment of the present invention. Rocking target 20 comprises hollow top piece 26, which is attached to first end 27 of curved stem 23, and base 30. Base 30 has a top surface 31 which is attached to second end 29 of curved stem 28. Hollow top piece 26 can be used to hold liquid such as water, beer, or wine, and it can also be used to hold paper or cards. Hollow top piece 26 is desirable to the present invention because it can be used for drinking games, wherein it can hold alcoholic drinks. Hollow top piece 26 can also hold paper or cards, which is desirable for use in card games or other games requiring use of paper, including games like truth or dare.
[0062] FIG. 3 shows a cut-away view of the present invention. Hollow top piece 26 of rocking target 20 is filled with wine 32, as one example. This is desirable to the invention for use at parties or as a drinking game. Though the figure shows hollow top piece 26 filled with wine, the reader will appreciate that hollow top piece 26 could be filled with any liquid, including other alcoholic drinks, water, and juice. The ability of rocking target 20 to hold a liquid is advantageous in that the user may enjoy the mere novelty of the ability of rocking target 20 to sway back and forth and return to a first stable state (upright position) when hit with a light force.
[0063] FIG. 4 is a bottom view of base 30, illustrating flat section 38, which is the surface 68 that rocking target 20 will lay flat on (not shown) when in its first stable state. Flat section 38 is necessary such that rocking target 20 may rest on surface 68 (not shown) when in its upright position. When rocking target 20 is hit with a force, it will teeter back and forth, much like the motion of a swinging pendulum, in a second stable state. So long as rocking target's 20 center of gravity remains within the positive stability margin, it will return from the second stable state to a first stable state, with rocking target 20 sitting upright, lying flat on flat section 38. Flat section 38 curves upward, creating curved section 36. Curved section 36 is attached to ledge 40, which creates ledge perimeter 41 along the edges of base 30. While this figure depicts ledge 40 and ledge perimeter 41, the reader will appreciate that the present invention does not require the presence of ledge 40 or ledge perimeter 41 in all embodiments.
[0064] FIG. 5 shows a side elevation view of base 30. Top portion 42 and bottom portion 44 will ofien be made as a single unified piecesuch as by injection molding. Flat section 38 is the portion of the base that customarily rests on a flat surface. Curved section 36 surrounds flat section 38. Ledge 40 surrounds curved section 36. Ledge perimeter 41 is the outermost edge of the ledge. In this example, curved stem 28 extends upward from top surface 31. Again, the reader will appreciate that ledge 40 and ledge perimeter 41 are optional.
[0065] FIG. 6 shows the rocking motion of rocking target 20 when hit with any outside force. Rocking target 20 will swing back and forth like a pendulum in a second stable state, until rocking target 20 eventually either returns to a first stable state or topples over into a third stable state. The version shown actually has three stable states and a plurality of metastable transition states. These various states create interesting motions and add to the excitement of the target games.
[0066] FIGS. 7A-7F illustrate these various states. The reader will appreciate that, while ledge perimeter 41 is shown in these figures as a reference point to gravity vector 74, ledge perimeter 41 is not required in the present invention and rocking target 20 will still have three stable states regardless of the presence of ledge 40 and ledge perimeter 41. FIG. 7A shows rocking target 20 in its first stable state. Flat section 38 of base 30 is resting on a surface 68 (such as a table top). Center of gravity 70 of the rocking target as a whole lies directly above flat section 38. The result is a stable state. In the context of this application this will be referred to as the first stable state.
[0067] FIG. 7B shows the same rocking target after it has been struck and tipped to one side. FIG. 7B shows the farthest tipping motion obtained. The contact between the tipping target and surface 68 is made at contact point 72. Gravity vector 74 passes vertically downward from center of gravity 79. The reader will observe how gravity vector 74 passes to the left of contact point 72. This means that the target will tip back to the left and eventually reach the first stable state again.
[0068] FIG. 7C shows the target after an even larger upsetting force has been applied. Gravity vector 72 now lies to the right of contact point 72, meaning that the target will now continue to tip further toward the right. However, the reader will note that gravity vector 74 lies to the left of ledge perimeter 41. The target will tip further to the right, but the tipping will be arrested (unless the dynamic rate of tipping is very high) when ledge perimeter 41 makes contact with surface 68. The result is that the target will again become stablebut this time in a leaning state (shown in FIG. 7F). This leaning state will be referred to as the second stable state. The second stable state provides interesting dynamics because the target will roll around on ledge perimeter 41. The rolling will continue for some time before the target comes to a complete stop.
[0069] FIG. 7D shows the tipping target after an even greater disturbing force has been applied. In this case the target has tipped sufficiently for the point of contact to become ledge perimeter 41. Gravity vector 74 now lies to the right of ledge perimeter 41. The target will thereore continue to tipall the way onto its side.
[0070] The fully tipped state is shown in FIG. 7E. This fully tipped configuration is referred to as the third stable state. Here, device 20 was hit too hard by an upsetting force, causing the device to completely topple over. Base 30 is no longer lying on flat section 38. Rather, the entire device 20 sits horizontally sideways on a surface 68.
[0071] FIG. 7F shows device 20 tipping to the eventual third stable state (not shown). Base 30 is no longer sitting upright on flat section 38 on a surface 68. Device 20 has rocked passed curved section 36 to the left onto ledge perimeter 41. From here, device 20 will topple completely over into the third stable state (not shown).
[0072] FIG. 8 shows the present invention with an optional shot glass holder top piece 46. Rocking target 20 still comprises a base 30 and a curved stem 28 but shot glass holder top piece 46 has replaced hollow top piece 26. Shot glass holder top piece 46 comprises a hollow cavity in the shape of a shot glass, such that a user may place a prior art shot glass 50 into the cavity. Shot glass holder top piece 46 is made so that a user may easily place and retrieve a prior art shot glass 50 from the shot glass-shaped hollow cavity. As shown, shot glass holder top piece 46 is made to fit a conventional rounded shot glass, but the reader will appreciate that optional shot glass holder top piece 46 may be shaped to fit any size or shape prior art shot glass 50.
[0073] FIG. 9 shows how a user would use rocking target 20 with shot glass holder top piece 46. The user may optionally place a prior art shot glass lid 52 on top of prior art shot glass 50 to prevent spillage in the event rocking target 20 topples over into its second or third stable states. The user would then place prior art shot glass 50 into shot glass holder top piece 46.
[0074] FIG. 10 illustrates another embodiment of the present invention. This embodiment is desirable for users that prefer to use rocking target 20 as a target practice game. This is because rocking target 20 comprises a target top piece attached to a straight stem 56. As shown, straight stem 56 is attached to the top surface 31 of a weight-holding base 58, but the reader will appreciate that rocking target 20 may alternatively comprise base 30. Target top piece 54 may be spherical (shown), or any other shape designed to be hit with a force, such as a conventional ovular target for practice, and may be solid or hollow on the inside. In a game using rocking target 20, the users will preferably aim to hit target top piece 54. When target top piece 54 is hit, rocking target 20 will move from the first stable state and begin to swing back and forth in a second stable state. If target top piece 54 is hit too hard with a force, the entire rocking target 20 will topple completely over to a third stable state.
[0075] FIG. 11 is a cut-away illustration of weight-holding base 58. Weight-holding base 58 has a cup 59, which has a hollow inside. The reader will appreciate that cup 59 of weight-holding base 58 can take any shape. Top portion 42 is shown below cup 59. In this embodiment, top portion 42 is hollow inside. Cup 59 is filled with sand 60 in the figure, but any other weight-bearing substance, such as a liquid, could also be used. Top portion 42 is attached to bottom portion 44, which comprises curved section 36 and a flat section 38. Device 20 (not shown) will rock on curved section 36 if hit with a force (second stable state). Flat section 38 makes contact with the surface 68 (not shown) that device 20 lies flat on in its upright position (first stable state). The reader will appreciate that top portion 42 bottom portion 44 can be any shape, so long as the base has a ledge and a curved section. Rocking target 20 will teeter back and forth in a second stable state when hit with a force. However, once rocking target 20 is hit too hard, it will enter into the negative stability margin (not shown) and, like other embodiments of the invention, will topple completely over into a third stable state.
[0076] FIG. 12 shows a perspective view of a third embodiment of the present invention. Rocking target 20 comprises an elongated boxed target piece 64 that is attached to a boxed base 66. Boxed target piece 64 has a length and takes the shape of an elongated cube or rectangular prism, with a height greater in length than its width. In this embodiment, rocking target 20 may be hit at any point along boxed top piece 64, and such force will cause rocking target 20 to teeter back and forth in a second stable state along boxed base 66. Though this embodiment is shown with the presence of boxed base 66, the reader will appreciate that boxed base 66 is not required in this embodiment.
[0077] FIG. 13 shows a detailed view of boxed base 66 of FIG. 12. Boxed base 66 is like alternative bases described in other embodiments of the invention in that it comprises curved section 36 and a flat section 38 on bottom surface 35 of boxed base 66. Rocking target 20 comprises four ledges 40, which are at the end of boxed top piece 64 that is attached to boxed base 66. Rocking target 20 lies upright on flat section 38. When hit with a force, rocking target 20 enters a second stable state and rocks back and forth along curved section 36. So long as rocking target 20 does not enter into the negative stability margin, rocking target 20 will not topple over from a second stable state into a third stable state. Rather, rocking target 20 will return from a second stable state to a first stable state. Again, the reader will appreciate that boxed base 66 is not required in this embodiment and is merely shown as an option.
[0078] The force used to hit rocking target 20 may be anything that would cause rocking target 20 to move from its first stable state, including for example a hand or foot, a ball, a bat, a projectile, or a golf club. Rocking target 20 may be made of any durable material, including wood, plastic, or the like. Preferably, hollow top piece 26 and shot glass holder top piece 46 will be made out of a liquid-resistant material. The top piece, stein, and base in any of the embodiments may be attached with any adhesive material, including glue, wood glue, or may be manufactured as one piece. Alternatively, the top piece, stem, and base in any embodiment may be magnetically attached to each other, such that when a user hits rocking target 20 with a force, the force overcomes the magnetic attraction and causes rocking target 20 to come apart. Any embodiments of the present invention may also have a meter placed inside of it, such that the force or angle can be recorded when a user hits rocking target 20.
[0079] The previously described embodiments of the present invention have many advantages. The invention allows user to play drinking or target games, wherein the object of the game may be either to cause rocking target 20 to topple over into a third stable state or cause rocking target 20 to swing back and forth in a second stable state without toppling completely over. The present invention may be used to hold liquid, such as when users want to play a drinking game or can include a target top piece for users that want to use rocking target 20 for target practice. Finally, rocking target 20 has different options for base pieces, wherein the base may incorporate a curved section and a ledge or a weight-holding base 58.
[0080] The particular embodiments described are preferred due to their advantages over the prior art but are not required in all versions of the invention. Importantly, the invention does not require that all the advantageous features described herein be incorporated into every embodiment of the invention.
[0081] The preceding description contains significant detail regarding the novel aspects of the present invention. It should not be construed, however, as limiting the scope of the invention but rather as providing illustrations of the preferred embodiments of the invention. As an example, rocking target 20 may contain a top piece that is any shape, including a target shape, a piece with a hollow cavity, or the shape of a rectangular prism.
