CHILDREN'S RIDE-ON VEHICLES AND PLAY SYSTEMS INCORPORATING WHEEL AND TRACK ASSEMBLIES

FIELD

The present disclosure relates to wheel and track assemblies for play systems incorporating children's ride-on vehicles, and to play systems that include such wheel and track assemblies.

BACKGROUND

Play systems come in many shapes and forms and include multiple components designed to be used together, for example a children's ride-on vehicle and a coordinating vehicle track. Children's ride-on vehicles are reduced-scale vehicles that are designed for use by children. For example, children's ride-on vehicles include a seat adapted to accommodate one or more children and steering and drive assemblies that are adapted to be operated by a child sitting on the seat. One type of drive assembly that is often used in children's ride-on vehicles includes a battery-powered motor assembly. When the motor assembly is energized, such as responsive to inputs from the child sitting on the seat, the powered, or driven, rotation of at least one of the children's ride-on vehicle's wheels results.

Play systems may include a track configured to define a path for a children's ride-on vehicle to ride along. Such a track may be utilized to define and/or limit the path of travel of a children's ride-on vehicle. For example, a play system may be utilized when the child driver of the ride-on vehicle is younger or otherwise less experienced operating the children's ride-on vehicle in an unrestricted manner and/or within an unrestricted area.

SUMMARY

Play systems of the present disclosure comprise a children's ride-on vehicle and a companion track that defines a path of travel for the children's ride-on vehicle. The children's ride-on vehicle and the track may be configured to cooperate with each other to inhibit, restrict, and/or prevent undesired separation of the children's ride-on vehicle from the track as the children's ride-on vehicle is operated on the track. The children's ride-on vehicle and the track each have one or more guide surfaces that are complementary to the companion apparatus and which are configured to guide the children's ride-on vehicle along a path of travel defined by the track. The children's ride-on vehicle may be powered, steerable, and configured to operate on and off the track. When the children's ride-on vehicle is guided and/or steered along the path of travel, the complementary guide surfaces do not substantially impede progress of the children's ride-on vehicle along the path of travel. When the children's ride-on vehicle is guided and/or steered away from the path of travel, the complementary guide surfaces contact and/or frictionally engage to direct the children's ride-on vehicle along the path of travel and/or to slow progress of the children's ride-on vehicle.

DESCRIPTION

FIGS. 1-10 illustrate play systems 10 and elements thereof according to the present disclosure. Elements that serve a similar, or at least substantially similar, purpose are labeled with numbers consistent among the figures. Like numbers in each of FIGS. 1-10, and the corresponding elements, may not be discussed in detail herein with reference to each of FIGS. 1-10. Similarly, all elements may not be labeled in each of FIGS. 1-10, but reference numerals associated therewith may be used for consistency. Elements, components, and/or features that are discussed with reference to one or more of FIGS. 1-10 may be included in and/or used with any of FIGS. 1-10 without departing from the scope of the present disclosure. In general, elements that are likely to be included are illustrated in solid lines, while elements that may be optional or alternatives are illustrated in dashed lines. However, elements that are shown in solid lines are not necessarily essential, and an element shown in solid lines may be omitted without departing from the scope of the present disclosure.

As schematically illustrated in FIG. 1, play systems 10 according to the present disclosure comprise a children's ride-on vehicle 20 and a track 60. The children's ride-on vehicle and the track of the play system are companion apparatuses that are configured to operate together for enhanced play value. However, the children's ride-on vehicle may be configured for on-track and off-track use and thus may be used independent of track 60. When used together to form a play system 10, the children's ride-on vehicle and the track cooperate with each other to inhibit, restrict and/or prevent separation of the children's ride-on vehicle from the track while the children's ride-on vehicle is operated by a child.

Children's ride-on vehicles 20 according to the present disclosure are reduced-scale vehicles configured for a child to ride and/or operate (e.g., drive). Children's ride-on vehicles generally are configured to mimic full-sized vehicles and comprise a reduced-scale vehicle body 22 sized for a child, a seat 24 sized for a child, and a plurality of wheels 40 operatively coupled to the vehicle body. When a child is sitting on seat 24 and conveying steering and/or other user inputs to the steering assembly and/or drive assembly of the children's ride-on vehicle, the child optionally may be referred to as a child operator. Children's ride-on vehicles are configured to travel by rolling on the plurality of wheels. The plurality of wheels is configured to support the weight of the children's ride-on vehicle, including the weight of a child seated upon the seat of the children's ride-on vehicle. Each wheel may support at least part of the children's ride-on vehicle.

Throughout this disclosure, general reference to top, bottom, front, back, left, right, forward, backward, inboard, and outboard are references to those directions with respect to the children's ride-on vehicle 20 in its normal, operational position (generally with the wheels 40 on the track, floor, ground, etc., and with the seat 24 above the bottom of the wheels). Left and right also refer to the left and right of a child operator while seated upon and operating the vehicle (facing forward). Inboard and outboard may additionally or alternatively be referred to as inner and outer, and/or as inwardly-facing and outwardly-facing, respectively. With respect to the track 60, the directions refer to a companion children's ride-on vehicle that is configured to operate on the track and to an operational position where the track is generally supporting the children's ride-on vehicle (e.g., the track generally is below the wheels).

As seen, for example, with reference to the general example of FIG. 1 and the more specific examples of FIGS. 2-4, each wheel 40 of the children's ride-on vehicle 20 includes a rim 46, two sidewalls 44 (e.g., an inboard sidewall and an outboard sidewall), and a hub 48. The rim is generally cylindrically shaped, with a generally circular profile, and is configured to support part of the weight of the children's ride-on vehicle, including the weight of a child seated upon the seat of the children's ride-on vehicle.

Each wheel 40 is configured to roll on the rim 46 (on a rolling surface 56) about a rolling axis 54 generally disposed through the geometric center of the rim and generally perpendicular to the generally circular profile of the rim. The rim is configured to roll along the track 60 and may be configured to roll along a surface off the track Likewise, the rolling surface may be adapted for on-track and off-track operation. For example, the rolling surface 56 may include a tread surface, a traction band, a tire, etc. At least when used independent of track 60, rolling surface 56 additionally or alternatively may be referred to as a ground-contacting surface 56.

The hub 48 of the wheel 40 is disposed toward the center of the wheel, encompassing the rolling axis 54. The two sidewalls 44 each span a side of the wheel between the rim 46 and the hub 48, such as which is better seen in the examples of FIGS. 2-4. The sidewalls may be continuous and/or solid surfaces, but it also is within the scope of the present disclosure that the sidewalls may include one or more gaps, voids, channels, recesses, spokes, etc. In FIGS. 2-4, (and subsequently discussed FIGS. 7-10) only one or two wheels 40 of a children's ride-on vehicle 20 are shown, in an effort to simplify the figures and focus on the wheel-track features being discussed. However, the inclusion of reference numbers 10 and 20 in FIGS. 2-4 (and FIGS. 7-10) schematically represents that FIGS. 2-4 (and FIGS. 7-10) should be understood to include the remainder of a children's ride-on vehicle 20, and thus a play system 10 with the vehicle and track 60.

Children's ride-on vehicles 20 according to the present disclosure are steerable and include one or more wheels 40 which are steerable wheels 82. Steerable wheels are configured to change the direction of travel of the wheel, and thus vehicle 20, by pivoting about an axis oblique (generally perpendicular) to the rolling axis 54 of the wheel (e.g., pivoting about a generally vertical axis when the vehicle is in an operational position). At least one of the steerable wheels 82 of children's ride-on vehicles 20 according to the present disclosure is a guide wheel 42, as discussed further herein. All steerable wheels 82 may be guide wheels, and all guide wheels 42 may be steerable wheels, although this is not required to all embodiments. Children's ride-on vehicles may comprise a steering assembly 30 coupled to one or more steerable wheels. The steering assembly is configured to translate steering inputs from a child operator of the children's ride-on vehicle into directional changes of the one or more steerable wheels (e.g., by changing the direction of travel). Thus, the steering inputs are able to redirect the children's ride-on vehicle and provide steering control to the child operator.

Tracks 60 according to the present disclosure are, and/or define, pathways configured for use by a children's ride-on vehicle 20. In particular, tracks 60 are reduced-scale, appropriately sized for a children's ride-on vehicle 20, and may be designed to mimic full-sized pathways such as automobile highways and/or railroads. As indicated in FIG. 1, tracks 60 define a path of travel 70 and comprise at least one rail 62, and optionally two rails 62, which is/are generally configured to guide the children's ride-on vehicle along the path of travel. The track 60 may comprise a track support surface 68 configured to support the children's ride-on vehicle, including a child seated upon the children's ride-on vehicle. In other words, the track support surface is configured to support the weight of a child seated upon the children's ride-on vehicle. The rail 62 generally protrudes above the track support surface when the track is in an operational position. The track support surface 68, and the track 60 generally, is/are configured to permit the children's ride-on vehicle 20 to roll along the track support surface. The rail(s) 62 and the track support surface 68 generally are adjacent, rigidly coupled, and together define the path of travel. Additionally or alternatively, the rail and/or the track support surface may be affixed to a rigid support (such as staked, pinned, or otherwise secured to a ground surface). At least where the rail is affixed to a rigid support, the track may not utilize and/or include a track support surface to define a stable path of travel. Where a track support surface is not included, the children's ride-on vehicle may roll on the surface (e.g., the floor, ground) adjacent to the rail. Additional illustrative, non-exclusive examples of tracks are disclosed in U.S. Provisional Patent Application No. 61/905,665 and U.S. patent application Ser. No. 14/272,740, each entitled “Track Assemblies and Track Assembly Kits for Children's Ride-On Vehicles,” the disclosures of which are hereby incorporated by reference.

Children's ride-on vehicles 20 and tracks 60 according to the present disclosure each include a guide surface that are complementary to the other. The children's ride-on vehicle 20 includes one or more wheel guide surfaces 52 that are on one or more wheels 40, which optionally may be steerable wheels 82, as discussed herein. The track 60 includes one or more track guide surfaces 66 that are on one or more rails 62. Play systems 10 are configured such that the wheel guide surface and the track guide surface may be selectively engaged (e.g., by steering the children's ride-on vehicle). When engaged, the wheel guide surface and the track guide surface form a frictional engagement that slows the progress of the children's ride-on vehicle along the path of travel 70 and/or guides (e.g., redirects) the children's ride-on vehicle toward/along the path of travel. For example, when the wheel guide surface is held forcibly in contact with the track guide surface (e.g., the children's ride-on vehicle is steered away from, or contrary to, the path of travel), the frictional engagement generally adds resistance to the progress of the children's ride-on vehicle and slows the children's ride-on vehicle. As another example, when the wheel guide surface bumps, or incidentally contacts, the track guide surface, the frictional engagement and/or complementary shape generally aligns the wheel, including the wheel guide surface, with the rail, including the track guide surface.

When the wheel guide surface 52 and the track guide surface 66 come into contact, the complementary shapes generally result in frictional contact, and/or engagement, and tend to align, direct, and/or redirect the wheel 40 along the path of travel 70, generally substantially parallel to the track guide surface. The wheel guide surface and the track guide surface may be configured to resist engagement, tending to maintain a separation between the two surfaces except when a force is applied to the wheel (and/or the rail) to cause contact between the surfaces. For example, contact between the wheel guide surface and the track guide surface may not be a stable equilibrium position. When the wheel guide surface and the track guide surface come into contact, the complementary shapes may urge, direct, and/or redirect the wheel away from the track guide surface. Hence, the configuration of the wheel guide surface and the track guide surface may enable the children's ride-on vehicle to progress along the path of travel without significant frictional engagement of the guide surfaces if the children's ride-on vehicle is steered, actively or passively, along, or consistent with, the path of travel. If the children's ride-on vehicle is steered, actively or passively, away from the path of travel, and consequently into the track guide surface, the contact and/or engagement will (re)direct the children's ride-on vehicle along the path of travel instead of the direction of steering.

FIG. 2 depicts an exploded, cross-sectional view highlighting the interface between a children's ride-on vehicle 20 and a track 60, including the wheel guide surface 52 and the track guide surface 66. The illustrated wheel 40 of FIG. 2 provides an example of a wheel that is both a steerable wheel 82 and a guide wheel 42. A guide wheel is configured to guide the children's ride-on vehicle along the path of travel 70 defined by the track (in FIG. 2, the path of travel would be generally perpendicular to the page). At least one sidewall 44 of the guide wheel is a guide sidewall 50 that includes the wheel guide surface 52. The guide sidewall, and hence the wheel guide surface 52, may be on the inboard or the outboard side of the guide wheel. In FIG. 2, the guide wheel is shown including a single guide sidewall 44, but it is within the scope of the disclosure that a guide wheel 42 may include more than one guide sidewall (such as a pair of guide sidewalls that optionally may have opposed and/or mirror-image configurations). The wheel guide surface may span a portion of the guide sidewall and may be a contiguous or broken surface. For example, the wheel guide surface may be an annular segment of the guide sidewall. As another example, one guide sidewall may include several wheel guide surfaces, potentially arranged in a regular pattern such as in spaced-apart, annular and/or radial segments. The guide sidewall, and hence the guide wheel, may include exactly one wheel guide surface.

As shown in FIG. 2, the guide sidewall 50 of the guide wheel 42 generally forms a bulge that protrudes from the generally cylindrical form of the rim 46. The bulge of the guide sidewall additionally or alternatively may be referred to as a flared region, a projecting region, an inclined region, and/or a guide-engaging region. Where the guide sidewall is on the inboard side of the guide wheel, the bulge generally extends toward the inboard (central) portion of the children's ride-on vehicle 20. Where the guide sidewall is on the outboard side of the guide wheel, the bulge generally extends toward the outboard direction (away from the center of the children's ride-on vehicle).

The wheel guide surface 52 of a guide wheel 42 according to the present disclosure is generally an integral portion of the bulge. The maximum width of the guide wheel at the wheel guide surface 52 is generally wider than the width of the rim and/or the rolling surface 56 of the rim, and the bulge and/or wheel guide surface may have any suitable shape, or form, to provide the cooperative, selective engagement with a companion track, as discussed herein. For example, the bulge, and optionally the wheel guide surface, may be convex, or include a convex portion. As another example, the wheel guide surface may have a tapered and/or a substantially frustoconical form, and the guide sidewall 50 may have a tapered and/or a substantially frustoconical form owing to the projecting wheel guide surface. Where the wheel guide surface and/or the guide sidewall has, or includes, a frustoconical form, the symmetry axis of the frusto-cone is substantially the same as the rolling axis 54 of the guide wheel. The wheel guide surface generally is at an incline (relative to vertical) when the guide wheel is in an operable position. The wheel guide surface is generally oblique, not essentially perpendicular, to the rolling surface of the rim and/or the rolling axis 54 of the guide wheel. The interior angle 58 between the wheel guide surface and the rolling surface is generally an obtuse angle. In profile (as depicted in FIG. 2), the wheel guide surface, and/or a portion thereof, may be curved and/or straight. Where the wheel guide surface is generally annular, the profile may have an upper portion and a lower portion (as also depicted in FIG. 2), corresponding to opposite sides of the annulus (i.e., the profile of the annulus on opposite sides of the rolling axis). The wheel guide surface may be symmetric about the rolling axis of the guide wheel and may present a constant profile as the guide wheel rolls. Additionally or alternatively, the wheel guide surface may be asymmetric or include asymmetric portions.

As discussed, a play system 10 according to the present disclosure includes a track guide surface 66 that is complementary to a wheel guide surface 52. Examples of these complementary surfaces are generally indicated in the schematic view of FIG. 1, and in the more detailed examples of FIGS. 2-4. Generally, the two complementary surfaces face each other and have substantially the same profile. Where the wheel guide surface is asymmetric, the track guide surface may be complementary to one or more orientations of the wheel guide surface and/or the average profile of the wheel guide surface. Generally, the two complementary surfaces are configured to frictionally engage with an extended contact, e.g., a line contact, rather than a single point contact common for rigid convex objects. The extended contact may be a contiguous contact or may be a series of contact points and/or contact regions. The extended contact generally extends radially along the guide wheel, i.e., extending toward the rim 46 and toward the hub 48 along the wheel guide surface.

As illustrated in the examples of FIGS. 2-4, the rail 62 of the track 60 generally has a sloped, or inclined, side which includes the track guide surface 66, i.e., the top of the rail is generally the narrowest portion of the rail. Hence, the track guide surface 66 may be sloped, or inclined, when the track is in an operational position. For example, from the base of the rail toward the top of the rail, an outboard track guide surface (facing outboard, on the outboard side of the rail) may be inclined inboard (i.e., toward an inboard portion of the rail), and an inboard track guide surface (facing inboard, on the inboard side of the rail) may be inclined outboard (i.e., toward an outboard portion of the rail). The track guide surface may be, or may include a portion that is convex, concave, and/or flat. In profile generally perpendicular to the path of travel (as depicted in FIG. 2), the track guide surface, and/or a portion thereof, may be curved and/or straight, e.g., including a curved segment and/or a straight segment. The profile of the track guide surface generally has the same sloped, or inclined, features as the corresponding surface, e.g., generally inclined toward a narrower top of the rail.

As indicated in at least FIGS. 1-4, track 60 may include a track support surface 68. Where the track includes a track support surface 68, the track guide surface is generally adjacent and/or associated with one or more track support surfaces. When the track is in an operational position, the track guide surface is generally above, i.e., more elevated than, the (adjacent and/or associated) track support surface, and hence, the track support surface is generally below, i.e., less elevated than the (adjacent and/or associated) track guide surface.

Relative to the guide wheel 42, the track guide surface 66 is generally oblique, not essentially perpendicular to, the rolling surface 56 of the rim 46 of the wheel. Relative to the track support surface 68, the track guide surface is generally oblique, not essentially perpendicular, to the track support surface. The exterior angle 72 between the track guide surface and the (adjacent and/or associated) track support surface is generally an obtuse angle, such as is illustrated in FIG. 2. The exterior angle 72 may be substantially the same as the interior angle 58 between the wheel guide surface and the rolling surface of the guide wheel.

The rail 62 of a track 60 according to the present disclosure may include one or more track guide surfaces 66 on one or more sides of the rail. For example, a rail may include a track guide surface on the inboard and/or the outboard side of the rail. The rail may include exactly one track guide surface and/or may include one or more track guide surfaces on only one side of the rail. The track guide surface may be a contiguous or broken surface. The rail may include several track guide surfaces arranged in a regular pattern such as segments spaced apart along the rail, along the path of travel.

As illustrated in FIG. 3, play systems 10 may include a children's ride-on vehicle 20 with at least two wheel guide surfaces 52 that are complementary to at least two track guide surfaces 66 of a track 60. FIG. 3 depicts an example where two guide wheels 42 interact with one or two rails 62. Each complementary pair of guide surfaces (i.e., a wheel guide surface and a track guide surface) independently may be configured to selectively, frictionally engage when the children's ride-on vehicle is steered away from, or contrary to, the path of travel.

Generally, when play systems 10 include more than one pair of complementary guide surfaces, the different pairs of guide surfaces may be configured to guide the children's ride-on vehicle in different directions and/or at different times. For example, one pair of guide surfaces may be configured to engage when the children's ride-on vehicle is steered to the left of the path of travel while another pair of guide surfaces may be configured to engage when the children's ride-on vehicle is steered to the right of the path of travel. As further examples, a pair of guide wheels (e.g., a first and a second guide wheel) each may have a wheel guide surface on the inboard side of the wheel, and a pair of complementary track guide surfaces may be on the outboard side of one or more rails. Similarly, a play system may include a pair of guide wheels that each has a wheel guide surface on the outboard side of the wheel and a pair of complementary track guide surfaces on the inboard side of one or more rails.

Where the play system 10 includes a pair of guide wheels 42, the guide wheels are generally spaced apart, such as in the illustrative example of FIG. 3. The guide wheels may be disposed on opposite sides of the children's ride-on vehicle 20, for example, on the left side (disposed toward the left side) and on the right side (disposed toward the right side). Additionally or alternatively, when a pair of guide wheels 42 are utilized, the guide wheels may be aligned with a common rolling axis 54, or have rolling axes that are approximately co-linear. Further, guide wheels may be arranged fore and aft of each other, and/or inboard and outboard of each other.

Where the play system 10 includes a pair of rails 62, the rails are generally spaced apart in a substantially parallel relationship. The rails may be disposed on opposite sides of the track 60, for example, on opposite sides of the path of travel 70 (e.g., to the left and to the right of the center of the path of travel). FIG. 3 provides an illustrative example of a play system 10 with a pair of spaced-apart rails 62. In FIG. 3, the path of travel, as defined by the rails, may be described as being into or out of the page. Where the rails are disposed on opposite sides of the track, the spacing between the rails may be referred to as the gauge of the rails and/or track. Additionally or alternatively, rails may be aligned (generally in a substantially parallel relationship) on one side of the track. Track 60 may be configured to dispose the rails at a substantially constant spacing (a substantially constant gauge) or may be configured to vary the spacing of the rails along the path of travel. For example, the track may define curved and straight portions of the path of travel, and the rail spacing may be different in the straight and curved portions (e.g., narrower in the straight portion or vice versa). As used herein, a substantially parallel relationship of rails includes substantially parallel straight rails, substantially parallel curved rails, a defined distance between rails, a substantially constant spacing and/or gauge, and rails in which the spacing and/or gauge varies smoothly along the length of the rails.

As disclosed in more detail herein, where the play system 10 includes a pair of guide wheels 42 and a pair of rails 62, the spacing between the guide wheels 42, measured perpendicular to the path of travel 70, may be wider, narrower, and/or the same as the spacing between the rails at a particular point along the path of travel. Additionally or alternatively, the spacing between the wheel guide surface of each of the pair of guide wheels, measured perpendicular to the path of travel, may be wider, narrower, and/or the same as the spacing between the track guide surface of each of the pair of rails. The spacing of the guide wheels is configured to allow the children's ride-on vehicle to progress along the path of travel without substantial frictional engagement of the guide surfaces.

A play system 10 may include a children's ride-on vehicle 20 with a guide wheel 42 including two wheel guide surfaces 52 facing opposite directions and a track 60 with two rails 62 each including a track guide surface 66 facing opposite each other. Similarly, a play system 10 may include a track with a rail including two track guide surfaces facing opposite directions and a children's ride-on vehicle with two guide wheels each including a wheel guide surface facing opposite each other.

FIG. 4 depicts one such example where one guide wheel 42 has a wheel guide surface 52 on each of the sidewalls 44 (hence both are guide sidewalls 50). The guide wheel is configured to roll between the two rails 62 of the track 60, with each rail including a track guide surface that faces one of the wheel guide surfaces. The guide wheel is configured to roll between the rails (without substantial frictional engagement of any of the guide surfaces) unless, or until, the guide wheel is steered away from the path of travel (generally perpendicular to the plane of FIG. 4).

Children's ride-on vehicles 20 may include a single guide wheel 42 such as the guide wheel 42 illustrated in FIG. 4. The guide wheel may be substantially centered under the midline of the children's ride-on vehicle. Additionally or alternatively, the guide wheel may be on the left side or the right side of the children's ride-on vehicle with other wheels 40 to the right or left, respectively, of the guide wheel.

FIG. 5 depicts an overview of illustrative, non-exclusive examples of play systems 10, children's ride-on vehicles 20, and tracks 60 according to the present disclosure.

Children's ride-on vehicles 20 may be shaped to generally resemble any type of vehicle, including reduced-scale, or child-sized, vehicles that are shaped to resemble corresponding full-sized, or adult-sized, vehicles, such as cars, trucks, construction vehicles, emergency vehicles, off-road vehicles, motorcycles, space vehicles, aircraft, watercraft and the like, as well as vehicles that are shaped to resemble fantasy vehicles that do not have a corresponding adult-sized counterpart. Although children's ride-on vehicle 20 is depicted in the figures in the form of a four-wheeled train locomotive, the components and/or features of a children's ride-on vehicle may be configured for use on and/or with any type of children's ride-on vehicle.

While children's ride-on vehicles 20 are generally depicted including four wheels, including two steerable wheels 82, any suitable number of wheels may be included as part of a children's ride-on vehicle according to the present disclosure, including two, three, four, or more than four wheels.

Vehicle body 22, wheel(s) 40, track 60, and/or rail(s) 62 typically are formed (at least substantially, if not completely) from molded plastic and may be integrally formed or formed from a plurality of parts that are secured together by screws, bolts, clips, or other suitable fasteners. The components may additionally or alternatively be formed at least partially from other suitable material(s), such as metal, wood, or composite materials. The components may include an underlying frame, or chassis. In such an embodiment, the components may be formed of metal and/or molded plastic, with the frame formed of metal and/or plastic.

Illustrative, non-exclusive examples of children's ride-on vehicles 20 that may include one or more guide wheels 42 and which optionally may be used with a track 60 to form a play system 10 are disclosed in U.S. Pat. Nos. 5,644,114, 6,105,982, 6,509,719, 6,554,087, 6,755,265, 6,771,034, 7,216,878, 7,413,041, 7,568,753, 7,905,305, 7,939,008, and 8,164,429, the disclosures of which are hereby incorporated by reference.

FIG. 5 also depicts an example of a suitable layout, or assembled configuration, for a track 60, which defines a path of travel 70 for the children's ride-on vehicle when the vehicle is used with the track. As depicted, the path of travel is approximately circular, and the path of travel is a corresponding (approximately) circular path that extends around the track. Tracks 60 are elongated and generally may be configured to form a circuit (e.g., a continuous loop or an open circuit). In FIG. 5, track 60 is depicted as including a plurality of interconnected curved track sections 61. It is within the scope of the present disclosure that track 60 may have a different number of track sections (optionally, only a single continuous section), and/or that the track sections may have different shapes, sizes, and/or orientations. For example, some tracks 60 may include straight portions (configured to guide a children's ride-on vehicle straight), curved portions (configured to guide a children's ride-on vehicle around a curve), cross-over portions, branches, and/or switches. For example, the track may define an oval path of travel, a figure-8 path of travel, and/or a branching network of travel paths. Tracks 60 may include cross ties, or cross members, 64 configured to span between the rails 62 and couple the rails together. The cross ties are configured to maintain the local spacing between the rails (i.e., the rails are generally rigidly coupled). Tracks 60 may include, and/or may be composed of, a plurality of track sections 61 that are configured to be assembled and disassembled. The track sections may include one or more rails and/or one or more cross ties. When a track includes a plurality of track sections, one track section may be straight (including a straight portion) and another track section may be curved (including a curved portion).

FIG. 6 is a schematic representation of optional steering assembly 30 and optional drive assembly 150 of children's ride-on vehicles 20. Steering assemblies 30 and drive assemblies 150 may be configured to cooperatively control the children's ride-on vehicle. Children's ride-on vehicles 20 may be (but are not required to be) powered, for example, battery powered. Children's ride-on vehicles 20 may be electrically powered with motors, or they may be child-powered (i.e., manually powered), such as with pedals or simply by the child pushing against the ground with his/her feet.

Steering assemblies 30 are configured to translate steering inputs of a child operator, such as a child sitting on a seat of the children's ride-on vehicle, into directional changes of the children's ride-on vehicle 20. Steering assemblies 30 may include a steering mechanism 32, such as handlebar(s), steering wheel(s), and/or steering lever(s). Steering mechanism 32 may be coupled, via a steering linkage 34, to at least one of the steerable wheels 82 in a manner to control the direction of the steerable wheel(s). Steering inputs by a child operator delivered to the steering mechanism are transferred, via the steering linkage, to the steerable wheel(s) to change the direction of travel of the steerable wheel(s) and thus the children's ride-on vehicle. The steering mechanism may be any suitable hand-operated mechanism to accept manual steering inputs from the child operator. The steering linkage may be any suitable linkage to transfer the steering inputs into directional changes of the steerable wheel(s). The steering linkage may translate rotary and/or linear inputs into rotary and/or linear outputs applied to the steerable wheel(s). The steering linkage may include rods, axles, shafts, collars, levers, gears, etc. Generally, all steerable wheels are coupled to, and controlled by, a steering assembly. One steering assembly may be configured to couple to, and to control, more than one, and potentially all, of the steerable wheels, including the guide wheels 42.

When the children's ride-on vehicle 20 is operated on the track 60, the steering assembly 30 optionally remains operational and may passively cooperate with the wheel guide surface(s) 52 and the track guide surface(s) 66 to guide the children's ride-on vehicle along the path of travel 70. Further, the child operator may use the steering assembly to guide children's ride-on vehicle 20 along the path of travel. If the child operator attempts to steer the children's ride-on vehicle contrary to the path of travel, the guide surfaces engage and cooperate to slow and/or guide the children's ride-on vehicle, as discussed further herein.

Illustrative, non-exclusive examples of steering assemblies 30 for children's ride-on vehicles 20 that may include one or more guide wheels 42 and which optionally may be used with a track 60 to form a play system 10 are disclosed in U.S. Pat. Nos. 6,105,982, 6,554,087, and 7,216,878, the disclosures of which are hereby incorporated by reference.

Drive assemblies 150 may include a battery assembly 152, a motor assembly 154 electrically coupled to the battery assembly, a driven wheel assembly 156 operatively coupled to the motor assembly, and one or more user input devices 158. One type of drive assembly 150 that often is used in children's ride-on vehicles includes a battery-powered motor assembly 154 that is adapted to drive the rotation of one or more of the vehicle's wheels 40, i.e., a driven wheel 84. As used herein, the term “driven wheel” refers to a wheel that is rotated directly in response to a rotational input from the drive assembly. A driven wheel also may be a steerable wheel 82 and/or a guide wheel 42. The driven wheel may be configured to be driven by the drive assembly at any suitable speed(s) and/or direction(s).

Battery assembly 152 may be and/or include one or more batteries 160 that are adapted to provide power to the motor assembly 154. The one or more batteries in the battery assembly may have any suitable construction, and in some embodiments may be rechargeable batteries.

Motor assembly 154 may be and/or include one or more battery-powered motors 162 that are adapted to drive the rotation of at least one wheel of the driven wheel assembly 156, which may include one or more driven wheels 84, depending on the configuration of the children's ride-on vehicle 20.

User input device(s) 158 are adapted to convey inputs from a child seated on the children's ride-on vehicle 20 to the drive assembly 150. That is, the input device(s) are configured to convey a user's inputs, such as via a wiring harness, to control the actuation of motor assembly 154, such as by causing the actuation (or energizing) of the motor assembly, selecting between a range of electronic configurations, selecting the direction of rotation of the motor assembly's output, selecting the relative degree to which the motor assembly is actuated, etc. An example of a suitable user input device 158 includes (but is not limited to) a drive actuator 166, through which a user input directing battery assembly 152 to energize the motor assembly is received. Examples of suitable drive actuators include an on/off switch, a foot pedal, a throttle lever, and a rotational handgrip on a steering mechanism 32 such as a handlebar. Other illustrative, non-exclusive examples of user input devices include a speed switch 168, which enables a user to select the relative rate of rotation of the motor assembly's output, and a direction switch 170, which enables a user to select the relative direction or rotation of the motor assembly and thereby selectively configure the children's ride-on vehicle to drive in a forward or reverse direction. When present, user input devices 158 may be located in any suitable location on the children's ride-on vehicle, e.g., the vehicle body 22 and/or the steering mechanism 32, for actuation by a child seated on the seat of the children's ride-on vehicle, such as while having at least one hand on the steering mechanism.

FIGS. 7-8 depict an illustrative, non-exclusive example of play system 10 in which guide wheels 42 are generally oriented along the path of travel 70 and with no significant contact, or engagement, between complementary pairs of guide surfaces (the proximate wheel guide surfaces 52 and track guide surfaces 66). The spacing of the guide wheels (and the wheel guide surfaces) relative to the spacing of the rails 62 (and the track guide surfaces) is configured to allow the children's ride-on vehicle 20 to progress along the path of travel with little or no contact between the wheel guide surface(s) and the track guide surface(s), and thus with little or no interference from the guide surfaces. As best seen in FIG. 8, when the guide wheels are directed substantially along the path of travel, the complementary wheel guide surface and track guide surface (and corresponding guide wheel and rail) are spaced apart. As discussed herein, if one of the wheel guide surfaces is steered (such as by a child sitting on the seat of the children's ride-on vehicle), or incidentally bumps, into the complementary track guide surface, the play system 10 is generally configured to return the guide wheels and rails to a spaced apart arrangement.

FIGS. 9-10 depict an illustrative, non-exclusive example of play systems 10 in which guide wheels 42 are oriented contrary to the path of travel 70 and with contact, and/or frictional engagement, between one or both complementary pairs of guide surfaces (the touching wheel guide surfaces 52 and track guide surfaces 66, as best seen in FIG. 10). In this configuration, whether by purposeful steering (such as by a child sitting on the seat of the children's ride-on vehicle) or incidental action (such as traversing a curved section of the track 60), the contact between the complementary guide surfaces redirects the guide wheel(s) back along the path of travel, and/or slows the children's ride-on vehicle 20 due to the additional friction of the contact. Though the children's ride-on vehicle may be powered, the contact between the complementary guide surfaces is configured to direct the children's ride-on vehicle along the path of travel rather than permitting the children's ride-on vehicle to follow the steered direction and potentially separate from the track.

As used herein, the terms “adapted” and “configured” mean that the element, component, or other subject matter is designed and/or intended to perform a given function. Thus, the use of the terms “adapted” and “configured” should not be construed to mean that a given element, component, or other subject matter is simply “capable of” performing a given function but that the element, component, and/or other subject matter is specifically selected, created, implemented, utilized, programmed, and/or designed for the purpose of performing the function. It also is within the scope of the present disclosure that elements, components, and/or other recited subject matter that is recited as being adapted to perform a particular function may additionally or alternatively be described as being configured to perform that function, and vice versa. Similarly, subject matter that is recited as being configured to perform a particular function may additionally or alternatively be described as being operative to perform that function.

As used herein, the term “and/or” placed between a first entity and a second entity means one of (1) the first entity, (2) the second entity, and (3) the first entity and the second entity. Multiple entities listed with “and/or” should be construed in the same manner, i.e., “one or more” of the entities so conjoined. Other entities may optionally be present other than the entities specifically identified by the “and/or” clause, whether related or unrelated to those entities specifically identified. Thus, as a non-limiting example, a reference to “A and/or B,” when used in conjunction with open-ended language such as “comprising” may refer, in one embodiment, to A only (optionally including entities other than B); in another embodiment, to B only (optionally including entities other than A); in yet another embodiment, to both A and B (optionally including other entities). These entities may refer to elements, actions, structures, steps, operations, values, and the like.

As used herein, the phrase “at least one,” in reference to a list of one or more entities should be understood to mean at least one entity selected from any one or more of the entity in the list of entities, but not necessarily including at least one of each and every entity specifically listed within the list of entities and not excluding any combinations of entities in the list of entities. This definition also allows that entities may optionally be present other than the entities specifically identified within the list of entities to which the phrase “at least one” refers, whether related or unrelated to those entities specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) may refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including entities other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including entities other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other entities). In other words, the phrases “at least one,” “one or more,” and “and/or” are open-ended expressions that are both conjunctive and disjunctive in operation. For example, each of the expressions “at least one of A, B and C,” “at least one of A, B, or C,” “one or more of A, B, and C,” “one or more of A, B, or C” and “A, B, and/or C” may mean A alone, B alone, C alone, A and B together, A and C together, B and C together, A, B and C together, and optionally any of the above in combination with at least one other entity.

The various disclosed elements of apparatuses and steps of methods disclosed herein are not required to all apparatuses and methods according to the present disclosure, and the present disclosure includes all novel and non-obvious combinations and subcombinations of the various elements and steps disclosed herein. Moreover, one or more of the various elements and steps disclosed herein may define independent inventive subject matter that is separate and apart from the whole of a disclosed apparatus or method. Accordingly, such inventive subject matter is not required to be associated with the specific apparatuses and methods that are expressly disclosed herein, and such inventive subject matter may find utility in apparatuses and/or methods that are not expressly disclosed herein.

In the event that any patents or patent applications are incorporated by reference herein and (1) define a term in a manner and/or (2) are otherwise inconsistent with either the non-incorporated portion of the present disclosure or with any of the other incorporated references, the non-incorporated portion of the present disclosure shall control, and the term or incorporated disclosure therein shall only control with respect to the reference in which the term is defined and/or the incorporated disclosure was originally present.

As used herein, the phrase, “for example,” the phrase, “as an example,” and/or simply the term “example,” when used with reference to one or more components, features, details, structures, embodiments, and/or methods according to the present disclosure, are intended to convey that the described component, feature, detail, structure, embodiment, and/or method is an illustrative, non-exclusive example of components, features, details, structures, embodiments, and/or methods according to the present disclosure. Thus, the described component, feature, detail, structure, embodiment, and/or method is not intended to be limiting, required, or exclusive/exhaustive; and other components, features, details, structures, embodiments, and/or methods, including structurally and/or functionally similar and/or equivalent components, features, details, structures, embodiments, and/or methods, are also within the scope of the present disclosure.

INDUSTRIAL APPLICABILITY

The systems and methods disclosed herein are applicable to the toy vehicle and children's products industries.
