Particular features of the vehicle (e.g., scooter) are described with reference to FIGS. 1-14. The scooter of FIGS. 1-7 can be substantially similar or identical to the scooter of FIGS. 8-13, or can be of another suitable arrangement. As mentioned above, the figures and description are illustrative only and are not intended to be limiting.

FIGS. 1-7 illustrate multiple views of a personal mobility vehicle in the form of a scooter. The illustrated scooter has a movable portion. The movable portion moves in response to rolling movement of the scooter along a surface. In some configurations, the movable portion comprises a portion of a character that is formed by the scooter body. In the illustrated arrangement, the movable portion is a portion of a head of the character, such as an upper portion of the head including the upper portion of a mouth of the character. In some configurations, the movable portion could be a lower portion of the head including the lower portion of the mouth. In various arrangements, the movable portion can provide the appearance of the character moving, such as the appearance of the character opening and closing its mouth. A pivot axis for the movable portion can pass through locations at or near rearward ends of the mouth of the character.

As shown in FIGS. 1-7, the scooter 100 comprises a body 102 that is supported for rolling movement on a surface by one or more wheels. In the illustrated arrangement, the scooter 100 comprises front and rear wheels 104, 106. In particular, the scooter 100 includes a pair of laterally-spaced front wheels 104 and a single, centrally-located rear wheel 106. However, in other arrangements, single front and rear wheels or a single front and a pair of rear wheels could be provided, among other possible arrangements. The front wheels 104 can be steerable wheels that provide for steering of the scooter 100. The wheels 104 can be supported by an axle that is rotatable about a steering axis. In some configurations, the scooter 100 can comprise a leaning-type steering arrangement, such as any of the types disclosed in U.S. Pat. No. 8,186,693 entitled TRANSPORTATION DEVICE WITH PIVOTING AXLE, the entirety of which is incorporated by reference herein.

The illustrated body 102 comprises a deck 108 extending between the wheels 104, 106 that provides a support surface for a user of the scooter 100 to place his or her feet. The body 102 also comprises a portion that is sculpted into the shape of a character. As described above, the portion can comprise a head of a character, such as a shark head in the illustrated arrangement. The character head 110 can be positioned at or near the front of the scooter 100, such as generally at or forward of the front wheels 104. Additional portions of the scooter 100 can form other portions of the character, such as the deck 108, for example. In the illustrated arrangement, a rear fender 112 of the rear wheel 106 can be in the form of a shark fin, for example. As used herein, the term “character” can include people, animals, imaginary beings, personified objects, cartoon characters, monsters, robots and other creatures. The scooter 100 can also include a body portion sculpted to resemble other objects, which can include a movable portion.

The scooter 100 can also comprise a steering mechanism, such as a handlebar assembly 120. The handlebar assembly 120 can include a pair of handgrip portions comprising handgrips 122. The handlebar assembly 120 can comprise a generally vertical support bar 124 that extends upwardly from a forward portion of the scooter body 102 and a horizontal bar 126 at or near an upper end of the vertical support bar 124. The handgrip portions comprising the handgrips 122 can be defined by or carried by the horizontal bar 126. In other arrangements, the steering mechanism can be omitted and the scooter 100 can be in the form of a skateboard, for example.

The character head 110 can comprise a mouth 130. As used herein, the term “mouth” has its plain and ordinary meaning, such as an opening or entrance to a structure that is hollow, concave, or almost completely enclosed. Unless otherwise stated, the term “mouth” is not limited to anatomical mouth structures and can include different types of structures. For example, the term “mouth” can include eyes or other openings or features.

As illustrated, the head 110 can include an upper portion 132 and a lower portion 134. In some embodiments, the upper portion 132 is above the mouth 130 and the lower portion 134 is below the mouth 130. The mouth 130 can define a separation between the upper portion 132 and the lower portion 134. An upper portion of the mouth 130 (e.g., including upper teeth) can form a portion or otherwise be carried by the upper portion 132. A lower portion of the mouth 130 (e.g., including lower teeth) can form a portion or otherwise be carried by the lower portion 134. In some configurations, the movable portion comprises the upper portion 132. In some configurations, the movable portion comprises the upper portion 132 and not the lower portion 134. In some configurations, the movable portion comprises the lower portion 134. In some configurations, the movable portion comprises the lower portion 134 and not the upper portion 132. In some configurations, the movable portion comprises both the upper portion 132 and the lower portion 134. Movement of the movable portion(s) can provide the appearance of the character head 110 opening or closing its mouth. In some configurations, the movable portion(s) can provide the appearance of other types of movement of a character or other object, such as other portions of the character head or face (e.g., eyes, tongue), character limbs (e.g., arms, legs) or other portions/objects.

With reference to FIG. 1, in the illustrated arrangement, the upper portion 132 of the character head 110 above the mouth 130 moves relative to the lower portion 134 below the mouth 130. The upper portion 132 pivots about a pivot axis 136 that extend through locations or points at or near rearward ends of the mouth 130. Alternatively, the upper portion 132 could move in a reciprocating fashion, any other suitable type of movement or combinations thereof.

As shown in FIGS. 8-11, the movement of the movable portion can be driven by the rolling movement of one or more of the wheels 104, 106. In the illustrated arrangement, the movement is driven by the non-steering or rear wheel 106, such that the overall structure is simplified. A motion transfer mechanism 140 transfers motion of the wheel (e.g., rear wheel 106) to the movable portion (e.g., upper portion 132 of the character head 110). The motion transfer mechanism 140 can comprise a gear, such as a worm gear 142, on the rear wheel 106, which drives a drive shaft 144 via a gear, such as a spur gear 146, which is engaged with the worm gear 142. Although not specifically illustrated, the drive shaft 144 can be supported by the body 102 of the scooter 100, including the deck 108, for example. The drive shaft 144 can be divided into two portions 144a, 144b, which can be rotatably coupled by a transmission 148. The transmission 148 can comprise two or more gears that transfer rotational motion between the drive shaft portions 144a, 144b. The transmission 148 can transfer motion at the same rotational speed/velocity or can provide a ratio that is other than a 1:1 ratio to change the rotational speed/velocity between the drive shaft portions 144a, 144b. In the illustrated arrangement, the transmission 148 is arranged to provide the driven or forward drive shaft portion 144a with a slower rotational velocity than the drive or rearward drive shaft portion 144b.

A motion conversion mechanism 150 can convert rotational movement of the drive shaft 144 into suitable motion for the specific movable portion, such as linear, translating or reciprocating movement, for example. In the illustrated arrangement, the motion conversion mechanism 150 comprises a cam 152 driven by the drive shaft 144 and a cam follower or push rod 154 driven by the cam 152. The push rod 154 is directly or indirectly connected to the movable portion to impart movement on the movable portion. The push rod 154 can be supported for reciprocating motion. In other arrangements, the push rod 154 could be supported for pivotal or rotational movement. The push rod 154 or the movable portion could comprise a biasing arrangement incorporating a biasing mechanism (e.g., spring) that biases the push rod 154 or movable portion toward a relaxed position. The cam 152 or other motion conversion mechanism 150 can move the push rod 154 or movable portion against the biasing force of the biasing mechanism. The movable portion can be constrained for movement with the push rod 154. In other configurations, the movable portion can be free to move in at least one direction relative to the push rod 154. For example, the push rod 154 could be configured to push the movable portion in an upward direction, but does not pull the movable portion in a downward direction. The movable portion can move downwardly with the push rod 154 under the influence of gravity or a biasing mechanism. Other suitable motion conversion mechanisms could also be used. The arrangement could comprise a clutch or other override mechanism that avoids or reduces damage to the motion transfer mechanism 140 or motion conversion mechanism 150 in the event that movement of the movable portion is constrained (e.g., by an external force) while a driving force is applied to the movable portion.

FIG. 11 illustrates another arrangement of the scooter 100 in which the drive shaft 144 is driven by the rear wheel 106 via a bevel gear arrangement 160. The transmission 148 is located at or near a front end portion of the scooter 100. A cam 152 is driven by an output of the transmission 148 and drives a push rod 154, which in turn moves the movable portion or upper portion 132 of the character head 110. In other respects, the scooter 100 of FIG. 11 can be the same as or substantially similar to the scooter 100 of FIGS. 1-10.

FIG. 12 illustrates another embodiment of a scooter 100. In some embodiments, including the illustrated embodiment, additional features may be added to the character head, such as fins, wings, etc.

FIG. 13 illustrates movement of the movable portion of the scooter 100 through a series of side views of the scooter 100 moving along a surface. Discrete positions of the movable portion are illustrated. However, the movement of the movable portion can be continuous between the illustrated positions, including relatively smooth movement between such positions. As illustrated in FIG. 13, the movable portion can move between first and second directions, such as in a first direction and then in an opposite direction (e.g., toward a closed position then toward an open position). In some configurations, the movable portion may move in a first (e.g., clockwise) direction and then in a second (e.g., counter-clockwise) direction, or vice versa. In some embodiments, the movable portion alternates (e.g., toggles) between moving in the first direction and the second direction. As discussed above with respect to FIGS. 1-7, the movable portion may be the upper portion, the lower portion, or both the upper and lower portions. In some embodiments, during movement in the first direction and/or second direction, the movable portion pivots at least about: 20°, 40°, 60°, 80°, 90°, 100°, values between the aforementioned values, or other values. In some implementations, the movable portion moves (e.g., pivots) a sufficient amount to substantially close the mouth 130 (e.g., to bring upper and lower lips of the mouth near or into abutment with each other). In some variants, the movable portion does not move (e.g., pivot) a sufficient amount to substantially close the mouth 130.

In some embodiments, during movement of the scooter on the wheels, the movable portion moves substantially independent of any action by the user or rider and/or the movable portion moves substantially automatically. For example, in some embodiments, motion of the movable portion, such as opening and closing the mouth as shown in FIG. 13, does not require additional input or actions by the user when the scooter is moving. This may be beneficial at least because the user can concentrate on riding without needing to concurrently operate an actuator (e.g., a hand lever or other mechanical control) to operate the movable portion. In some embodiments, the rate at which the movable portion moves depends (e.g., linearly or non-linearly) upon the rate of speed of the scooter. For example, the speed (e.g., rotational speed) of the movable portion can increase as the speed (e.g., speed along the ground) of the scooter increases, and/or the speed of the movable portion can decrease as the speed of the scooter decreases. In some implementations, the scooter is configured (e.g., through gearing) to multiply or reduce the speed of one or more of the wheels, such that the movable portion moves more rapidly or more slowly than the wheels.

CONCLUSION

It should be emphasized that many variations and modifications may be made to the herein-described embodiments, the elements of which are to be understood as being among other acceptable examples. All such modifications and variations are intended to be included herein within the scope of this disclosure and protected by the following claims. Moreover, any of the steps described herein can be performed simultaneously or in an order different from the steps as ordered herein. Moreover, as should be apparent, the features and attributes of the specific embodiments disclosed herein may be combined in different ways to form additional embodiments, all of which fall within the scope of the present disclosure.

Conditional language used herein, such as, among others, “can,” “could,” “might,” “may,” “e.g.,” and the like, unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments include, while other embodiments do not include, certain features, elements and/or states. Thus, such conditional language is not generally intended to imply that features, elements and/or states are in any way required for one or more embodiments or that one or more embodiments necessarily include logic for deciding, with or without author input or prompting, whether these features, elements and/or states are included or are to be performed in any particular embodiment.

Moreover, the following terminology may have been used herein. The singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to an item includes reference to one or more items. The term “ones” refers to one, two, or more, and generally applies to the selection of some or all of a quantity. The term “plurality” refers to two or more of an item. The term “about” or “approximately” means that quantities, dimensions, sizes, formulations, parameters, shapes and other characteristics need not be exact, but may be approximated and/or larger or smaller, as desired, reflecting acceptable tolerances, conversion factors, rounding off, measurement error and the like and other factors known to those of skill in the art. The terms “approximately,” “about,” and “substantially” mean that the recited characteristic, parameter, or value need not be achieved exactly, but that deviations or variations, including for example, tolerances, measurement error, measurement accuracy limitations and other factors known to those of skill in the art, may occur in amounts that do not preclude the effect the characteristic was intended to provide. The term “generally” as used herein represents a value, amount, or characteristic that predominantly includes, or tends toward, a particular value, amount, or characteristic. As an example, in certain embodiments, as the context may dictate, the term “generally parallel” can refer to something that departs from exactly parallel by less than or equal to 20 degrees and/or the term “generally perpendicular” can refer to something that departs from exactly perpendicular by less than or equal to 20 degrees.

Numerical data may be expressed or presented herein in a range format. It is to be understood that such a range format is used merely for convenience and brevity and thus should be interpreted flexibly to include not only the numerical values explicitly recited as the limits of the range, but also interpreted to include all of the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. As an illustration, a numerical range of “about 1 to 5” should be interpreted to include not only the explicitly recited values of about 1 to about 5, but should also be interpreted to also include individual values and sub-ranges within the indicated range. Thus, included in this numerical range are individual values such as 2, 3 and 4 and sub-ranges such as “about 1 to about 3,” “about 2 to about 4” and “about 3 to about 5,” “1 to 3,” “2 to 4,” “3 to 5,” etc. This same principle applies to ranges reciting only one numerical value (e.g., “greater than about 1”) and should apply regardless of the breadth of the range or the characteristics being described.

A plurality of items may be presented in a common list for convenience. However, these lists should be construed as though each member of the list is individually identified as a separate and unique member. Thus, no individual member of such list should be construed as a de facto equivalent of any other member of the same list solely based on their presentation in a common group without indications to the contrary.

Furthermore, where the terms “and” and “or” are used in conjunction with a list of items, they are to be interpreted broadly, in that any one or more of the listed items may be used alone or in combination with other listed items. The term “alternatively” refers to the selection of one of two or more alternatives, and is not intended to limit the selection to only those listed alternatives or to only one of the listed alternatives at a time, unless the context clearly indicates otherwise.

Some embodiments have been described in connection with the accompanying drawings. The figures are drawn to scale, but such scale should not be limiting, since dimensions and proportions other than what are shown are contemplated and are within the scope of the disclosed invention. Distances, angles, etc. are merely illustrative and do not necessarily bear an exact relationship to actual dimensions and layout of the devices illustrated. Components can be added, removed, and/or rearranged.
