FIG. 1 illustrates a kart having certain features, aspects and advantages of the present invention. The kart includes a body 10, which includes a first or rear portion 20 and a second or front portion 30. Preferably the front portion 30 is rotatably coupled to the rear portion 20. The rear portion 20 includes a seat portion 22 configured to allow a rider to be seated thereon. The rear portion 20 also supports at least one rear wheel 24. In a preferred embodiment, the rear portion 20 supports two rear wheels 24 and in other embodiments the rear portion 20 can support more than two rear wheels. The rear wheels 24 are coupled to the bottom of the rear portion 20. In some embodiments, the rear wheels 24 are swivel or caster wheels configured to rotate relative to the rear portion 20 about a swivel axis. Preferably, the rear wheels 24 are located below and toward a rearward end of or behind the seat portion 22. In some embodiments, the rear portion 20 curves upward or extends upward at the rear end of the rear portion behind the seat portion 22. Preferably, the rear portion 20 also includes an outer shell or cover portion 26. In some embodiments, the outer shell or cover portion 26 is located in front of and adjacent to the seat portion 22 and can resemble a head of an animal, insect or character, for example.
As illustrated, the outer cover portion 26 preferably includes one or more openings or window portions 28. In some embodiments, the one or more openings or window portions 28 are configured to allow a person to see through the outer cover 26. In one embodiment, the window portions 28 comprise a translucent or transparent material. In another embodiment, the window portions 28 comprise cut-out portions in the outer cover portion 26. Preferably, the window portions 28 are circular and are located near the front of the outer shell or cover 26. The outer shell 26 can also include visual features on the surface of outer shell 26 or extending therefrom. For example, the outer shell 26 can include protruding features such as protrusions resembling antennae 27 or features painted or printed on the surface such as features resembling a mouth 29 or ears. In some embodiments, the outer shell 26 is configured with visual features that resemble an animal, insect or cartoon character.
As illustrated, the front portion 30 includes a coupling portion 38 that is configured to be coupled to the rear portion 20. The front portion 30 also supports at least one front wheel 34. In a preferred embodiment, the front portion 30 supports two front wheels 34 and in other preferred embodiments, the front portion 30 supports only one front wheel or more than two front wheels 34. Preferably, the front portion 30 also supports a handlebar assembly 32 configured to allow a user to move and/or steer the kart. The handlebar assembly 32 preferably extends from the front of the kart backwards toward the rear portion 20 so that a user can access the handlebar assembly 32 with his or her hands. The handlebar assembly 32 also preferably includes grips 36 accessible to the hands of a user. Preferably, the front portion 30 in configured to extend away from the rear portion 40 in the forward direction and the handlebar assembly 32 is supported by the front portion 30 at a location forward from the rear portion 20 so that a user riding the kart can rest his feet on a portion of the handlebar assembly 32 in front of the rear portion 20. In some embodiments, the handlebar assembly 32 includes a substantially straight portion or portions 45 located near the front of the kart and configured to support a user's foot as the user rides the kart. Preferably, the handlebar assembly 32 also includes two end portions 42 that extend backward toward the rear portion 20 of the kart. Preferably, the end portions 42 also curve or extend upward and include the grips 36 that are accessible to a user riding the kart.
In some preferred embodiments, the front portion 30 is rotatably coupled to the rear portion 20 and rotates relative to the rear portion 20 about an axis. Preferably the axis is generally or substantially vertical and/or normal to the riding surface. Preferably, the front wheels 34 are positioned behind the axis and under the rear portion 20. Preferably, the entire front portion 30, including the handlebar assembly 32 and the front wheels 34, rotate about the axis relative to the rear portion 20. Each of the front wheels 34 can also rotate about its own wheel axis. Because the rotational axis and/or contact patch of the front wheels 34 is spaced behind the steering axis, oscillating movement or repeated back-and-forth rotation of the front portion 30 also creates a motive force for the kart. In some embodiments, the front wheels 34 can be swivel or caster wheels that are configured to rotate about a swivel axis relative to the front portion.
As illustrated, the front portion 30 also includes an inner member or inner surface portion 39. Preferably, the inner surface portion 39 moves relative to the outer shell or cover 26 of the rear portion 20 as the front portion 30 rotates relative to the rear portion 20. The inner surface 39 is at least partially nested within or covered by the outer cover portion 26 and the inner surface 39 preferably has the same, similar or compatible shape as part of the outer cover portion 26. In some embodiments, the inner surface 39 is curved or spherically shaped (e.g., hemi-spherical) and the outer cover portion 26 is also curved or spherically shaped (e.g., hemi-spherical) so that the two surfaces can be positioned adjacent to one another and move relative to one another. In a preferred embodiment, the inner surface 39 and the outer cover portion 26 have the same curvature and the inner surface 39 is configured to slide along the inside of the outer cover portion 26. Preferably, the inner surface 39 is coupled to the coupling portion 38 and extends upward from the coupling portion 38 and front portion 30.
Preferably, a portion of the inner surface 39 is visible through the window portion or opening 28 on the outer cover portion 26. In some embodiments, the window portion 28 comprises a translucent or transparent material that makes the underlying inner surface portion 39 visible. In other preferred embodiments, the window portion 28 is a void or opening in the outer cover portion 26 through which portions of the inner surface 39 are visible. Preferably, the inner surface 39 includes one or more visual features 40 that are visible through the window portion 28. As the inner surface 39 moves relative to the outer cover portion 26, the visual feature 40 moves relative to the window portion 28 which can provide a desired visual effect. For example, in a preferred embodiment, the inner surface 39 includes two visual features 40 that resemble eyes or the iris and pupil portions of an eye. The outer cover portion 26 includes two window portions 28, and one of the visual features 40 is visible through each of the window portions 28. The visual features 40 that resemble eyes can move side to side relative to the window portions 28 as the inner surface 39 moves relative to the outer cover portion 26. This results in a visual effect resembling eyes moving side to side as the handlebar assembly 32 rotates from side to side. This embodiment also results in the desired effect that the eyes or visual features 40 follow the direction of the handlebar assembly 32 and front portion 30 as a user steers the kart. Preferably, the visual features 40 move to point in the direction that the kart is moving or being steered. In alternative arrangements, a portion of or component connected to and movable with the inner surface portion 39 can extend to the outside of the cover 26, such as through openings (e.g., window portions 28) or from underneath of the cover 26, such that the exposed portion or component is visible and creates a desired visual effect upon steering or other movement of the kart. In other arrangements, the visual feature can be color(s) or symbols (e.g., words) that can move relative to another portion of the kart (e.g., the cover 26) and can be exposed or hidden as a result of steering or other movement of the kart, for example. Thus, for example, the exposed color could move or could change as a result of steering or other movement of the kart. Or, an exposed word(s) or other symbols could changes as a result of steering, such as the words “left” or “right” depending on the steering direction, which could be visible to a user of the kart, if desired.
As illustrated in FIG. 4, in some embodiments the visual features 40 are substantially centered within the window portions 28 when the front portion 30 and handlebar assembly 32 are in a position pointing straight forward relative to the rear portion 20. Preferably the visual features 40 resemble eye portions and are centered within the window portions 28 when the front portion 30 is in a centered position relative to the rear portion 20 and not rotated to one side or the other.
As illustrated in FIG. 5, in some embodiments the visual features 40 move to the right side of the window portions 28 when the handlebar assembly 32 is rotated to the right relative to the rear portion and the inner surface 39 rotates to the right. Preferably, this provides the visual effect of the visual features 40, which resemble eyes, moving to the right as the handlebar assembly 32 is steered to the right.
As illustrated in FIG. 6, in some embodiments the visual features 40 move to the left side of the window portions 28 when the handlebar assembly 32 is rotated to the left relative to the rear portion and the inner surface 39 rotates to the left. Preferably, this provides the visual effect of the visual features 40, which resemble eyes, moving to the left as the handlebar assembly 32 is steered to the left. In other embodiments, the visual features 40 can move in an opposite direction relative to the direction of movement of the handlebar assembly 32 or front portion 30. In some embodiments, the movement of the visual features 40 relative to the window portions 28 can include a vertical component.
Although the embodiments of the invention presented herein have been disclosed in the context of certain preferred embodiments and examples, it will be understood by those skilled in the art that the invention extends beyond the specifically disclosed embodiments to other alternative embodiments and/or uses of the invention and obvious modifications and equivalents thereof. Thus, it is intended that the scope of the invention herein disclosed should not be limited by the particular embodiments described above, but should be determined only by a fair reading of the claims that follow.
