Definitions
- Tracks for toy vehicles may be specific to the design of the toy vehicle, often being manufactured to include slots as guides. Freely steering toy vehicles on many conventional tracks may not be possible. This is particularly problematic for toy vehicles having more advanced features such as steerable wheels, finger- engageable steering mechanisms, hnked turning wheels, and/or wheels with negative camber for improved cornering, as opposed to toy vehicles that are merely pushed by a user and lack steering mechanisms. Thus, the variety of track types is limited and may not be appropriate for toy vehicles with such advanced features that support vehicle steering. Specific track designs may provide various benefits in some design aspects but lack in others. For example, a track composed of one type of material may provide rigid support but fail to allow toy vehicles to gain optimal traction on the surface.
- Rigid materials such as plastics used in constructing tracks may be injurious during play as well as difficult to walk over or maneuver around when engaging in play, particularly for children. This may be distracting and impede time spent on interaction and creative play, also detracting from a potential for adult-child interaction.
- toy tracks may be unwieldy to assemble or move, and may come apart easily, thus impeding play.
- Track constructions may also offer only minimal variety for play driving. For example, conventional tracks may be generally operable only along a single plane of a floor or table surface.
- a toy vehicle track system may include a plurality of track sections.
- Each track section may be formed within a section of a regular polygonal grid unit and may have at least two terminal ends at edges of the regular polygonal grid unit.

- FIG. 1 illustrates one example implementation of the toy vehicle track system 12.
- a plurahty of track sections 14 are connected to form a continuous track on which toy vehicles 40 may be guided.
- a toy vehicle 40 shown on the track system 12 may be guided along the track by a user via hand power, finger driving, or similar modes of propulsion, as well as downhill coasting along inclined portions of the track in which the vehicle may be released by the user.
- Several types of track sections 14 are shown in FIG. 1 and detailed in FIGS. 2-4 and FIGS. 5A-5C.
- Each track section 14 may have at least two terminal ends 24, although it will be appreciated that in other configurations a track section 14 may have only a single terminal end 24.
- Types of track sections 14 may include at least a straight track section 28 as shown in FIG. 2, a curved track section 30 as shown in FIG. 3, a Y-shaped track section 32 as shown in FIG. 4, transitioning track sections 36 as shown in FIGS. 11A, 11B and 12, and a U- shaped track section 39 as shown in FIGS. 11B. It will be appreciated that other configurations of track sections 14 may be possible, including X-shaped track sections 62, r-shaped track sections 64, track sections that feature jumps or ramps, and other geometries with one or more terminal ends 24.
- FIG. 5A An example implementation of an X-shaped track section 62 is shown in FIG. 5A; an example of an r-shaped track section 64 is shown in FIG. 5B.
- FIG. 5C depicts two r-shaped track sections 64 connected to a Y-shaped track section 32 at a portion of a track in a connected state.
- FIG. 6 illustrates a geometric configuration of the track sections 14 according to one example implementation.
- the construction of the track sections 14 is executed to secure precise and tight connection between the track sections 14 and to increase the number of connection permutations possible with a finite number of track sections 14.
- Each track section 14 may be formed within a section of a regular polygonal grid unit 20 belonging to a regular polygonal grid 34, the track section 14 having at least two terminal ends 24 at edges 22 of the regular polygonal grid unit 20.
- the polygonal grid units 20 and the polygonal grid 34 are mathematical objects, and as such, represent idealized geometries. Thus, they are virtual rather than physical in nature.
- a U-shaped track section 39 may include the sections of a plurality of the regular polygonal grid units 20.
- the U-shaped track section 39 may be formed by continuously joining three curved track sections 30, which may take the form of the U-shaped track section 39 as shown in FIG. 11B.
- One potential advantage of this configuration is a regular pattern of connection between track sections 14 that, being geometrically precise, aids in holding the track sections 14 together in the completed track. This feature is particularly important given the stress to which the track may be exposed during repeated assembly/disassembly and play. Additionally, this configuration featuring sections of regular polygonal grid units 20 belonging to a regular polygonal grid 34 may assist younger children in being successful at constructing multi-section track assemblies due to the regular patterning of connections between track sections 14.
- a width W of the straight track section 30 may be in a range of 5 inches to 6 inches and a length L of the straight track section 30 may be in a range of 11 inches to 12 inches.
- the width W may be 5.75 inches and the length L may be 11.6 inches.
- Dimensions of the regular polygonal grid unit 20 are also indicated in FIG. 6. In the example implementation shown in FIG.
- a hexagon that is the regular polygonal grid unit 20 belonging to the regular polygonal grid 34 having a hexagonal pattern may have a length along one side S in a range of 6 inches to 7 inches, a length between two opposite sides SS in a range of 11 inches to 12 inches, and a length between two opposite corners CC in a range of 13 inches to 14 inches.
- the length along one side S may be 6.75 inches
- the length between two opposite sides SS may be 11.6 inches
- a length between two opposite corners CC may be 13.5 inches. It will be appreciated that other dimensions are also possible as these values are merely exemplary.
- each track section 14 may include interlocking structures 26 (e.g., projections 66 and recesses 68) that interlock with the interlocking structures 26 of at least a second track section 18. This is shown, for example, in FIG. 6 between the curved track section 30, which is a first track section 16 in this example, and the straight track section 28, which is the second track section 18 in this example.
- interlocking structures 26 e.g., projections 66 and recesses 68
- Each track section 14 may be at least partially or entirely composed of foam.
- One potential advantage of such a configuration is that the track sections 14 may be deformable and unlikely to produce injury to a user should impact between the user and the track sections 14 occur, whether during track construction, play, or inadvertently when a user moves around or over the track.
- the foam is ethylene -vinyl acetate (EVA) foam.
- EVA ethylene -vinyl acetate
- the use of this particular material has at least several potential advantages.
- the texture of EVA foam is such that the track may be sturdy and endure under repeated stress and wear, while also being deformable and less likely to cause injury compared to rigid toy car track materials including hard plastics.
- the track sections 14 may be placed on various surfaces such as wood, carpet, etc., as EVA foam exhibits a high adhesion to many types of flooring. EVA foam texture and surfaces may also be advantageous in that friction forces between the toy vehicle 40 and the track may be optimal for propulsion of the toy vehicle 40 along the track. A“stickiness” inherent in EVA foam may work in favor of adhering the track sections 14 to each other at the connection areas of the interlocking structures 26. Track sections 14 may therefore be less likely to separate during play. Additionally, EVA foam is inexpensive to manufacture, decorate, and die cut into desired shapes.
- the regular polygonal grid unit 20 may belong to a regular polygonal grid 34 having a pattern of hexagonal, rectilinear, or triangular, to name a few example implementations as shown in FIGS. 7A-7C. It will be appreciated that other regular polygonal grids 34 may be implemented, such as those with multiple types of regular polygons and vertices or tiling patterns, as advantageous for track design or inventive play. Freeform designs may also be employed, or combinations of regular and freeform constructions.
- FIG. 8 is a perspective of a straight track section 28.
- the perspective shows a side of the track section 14 with a thickness T.
- the EVA foam may have a thickness T in a range of 3/8 inches to 1/2 inches.
- the EVA foam may be textured on at least one surface of the track section 14.
- the straight track section 28 as shown in FIG. 8 is one example implementation of a track section 14 where texturing simulates the presence of rock protrusions in the track section 14. Texturing of the track sections 14 may have at least one potential advantage of increasing types of play with a toy vehicle 40 on the track system 12.
- Track sections 14 may additionally include banked track sections 58 having banked curves 60 as shown in FIG. 13. Banked curves 60 and texturing may be employed to create different simulated road conditions during play with a toy vehicle 40 along the track system 12.
- the track sections 14 may be designed to simulate an asphalt or concrete surface of a street environment or a race-track environment.
- track sections 14 may include markings, texturing, and/or signage typical of city streets or other public roadways.
- track sections 14 may include such banked curves 60 and/or markings indicative of professional race-track environments.
- the track sections 14 may be designed to simulate a dirt or mud track, including a variety of protrusions, indentations, texturing, and the like.
- Track sections 14 with different types of texturing and design may be connected to each other; for example, a dirt- track section 72 may be connected to a race-track section 74 that may be connected to an off-road type track section 76 having simulated rock protrusions as shown in FIG. 15.
- the user may engage with the track system 12 by exercising a choice in the connection of track sections 14 to each other, thus possibly increasing a potential for play.
- the interlocking structures 26 may connect at least a first track section 16 with at least a second track section 18 to form a dovetail joint 38.
- This type of connection is depicted in FIG. 9.
- a projection 66 of the dovetail joint 38 may extend from a distal end of a right-end short edge of each track section and a recess 68 of the dovetail joint 38 may extend from a distal end of a left-end short edge of each track section 14.
- the interlocking structures 26 may interface interchangeably when oriented with the top side 50 up.
- track sections 14 may be secured to each other sufficiently to endure stress during play and hold together while the track is being used, yet still be easily assembled and disassembled.
- lane indicators 52 may be included on the top surface of the top side 50 of each track section 14 to indicate at least two lanes 54, 56 on each track section 14 as shown in FIGS. 2-4.
- the projections 66 of the dovetail joints 38 may extend once per indicated lane of the at least two lanes 54, 56 of each track section 14.
- dovetail joints are illustrated, other types of interlocking joints may be used, such as a dowel joint, finger joint, tongue and groove joint, dado joint, mortise and tenon joint, or bridle joint.
- FIGS. 10A- 10C illustrate several possible track layouts using a 20 -piece track section kit. As may be seen, forming the various track layouts presents a user with a variety of choices, expanding a potential for interaction and play with the track system 12.
- a track system 12 may not be limited to 20 pieces, as shown in FIGS. 14 and 15.
- the track system 12 may be constructed to include transitioning track sections 36 curved in a direction perpendicular to a flat upper surface of a flat track section.
- the transitioning track sections 36 may be configured to connect at least a first track section 16 at an angle «relative to at least the second track section 18, where the angle «may be 90 degrees.
- This may be advantageous when the track system 12 includes at least one track section 14 that is a wall-mounted track section.
- a first wall-mounted track section 42 may be connected to at least one floor track section 46, the first wall-mounted track section 42 and the floor track section 46 connected via at least one transitioning track section 36.
- a first wall-mounted track section 42 may be connected to at least a second wall-mounted track section 44, the first wall-mounted track section 42 and the second wall-mounted track section 44 connected via at least one transitioning track section 36.
- the transitioning track sections 36 may be designed for routing the track from floor-based track sections to wall-mounted track sections or a wall-mounted track surface 33, as shown in FIGS. 11A- 11B.
- the transitioning track section 36 may connect at least a floor- based track section at an angle a relative to either a wall-mounted track section (depicted in FIG. 11B as a U-shape track section 39) or a wall-mounted track surface 33 (e.g., depicted in FIG. 11A).
- transitioning track section 36 may include a rear cutout section that accommodates baseboard trim as may be found in a typical home environment (e.g., as depicted in FIGS. 11A and 12 for the right-hand track section 36).
- Wall-mounted track surface 33 may be mounted to a wall and a user may operate a toy vehicle 40 on the wall- mounted track surface 33.
- Wall-mounted track surface 33 may take the form of a contiguous sheet of material upon which a track graphic is printed or otherwise visually depicted.
- TYVEK may be used as the material for the wall-mounted track surface 33 due to its properties as being lightweight, non -stretching, and durable.
- the SOFT STRUCTURE or“soft hand” form of TYVEK may provide the advantage of not wrinkling when folded, rolled, or compressed for storage, thereby ensuring smooth track surfaces for vehicle play.
- transitioning track section 36 may include a first end (e.g., the floor side) having interlocking structures 26 that interface with interlocking structures 26 of a floor-based track section (e.g., first track section 16), and a second end (e.g., the wall side) that forms a ramp that interfaces with the wall-mounted track surface 33 to provide a smooth transition between the floor-based track section and the wall-mounted track surface 33.
- FIG. 11B depicts the use of wall-mounted track sections in which any of the previously described track sections may be wall- mounted to enable vehicle play on both vertical and horizontal surfaces.
- a U-shaped track section 39 and transitioning track sections 36 may include interlocking structures 26 at each end to form a track assembly that spans floor and wall surfaces.
- transitioning track section 36 may include a first end (e.g., the floor side) having interlocking structures 26 that interface with interlocking structures 26 of a floor- based track section, and a second end (e.g., the wall side) having interlocking structures 26 that interface with interlocking structures 26 of a wall-mounted track section (e.g., U-shaped track section 39).
- a semi-permanent adhesive may be used to secure wall-mounted track surface 33 or wall-mounted track sections to a wall.
- BLUESTIK reusable adhesive putty may be used to secure track sections to a wall.
- other suitable adhesives may be used including semi-permanent and permanent adhesives.
- wall transitioning track section 37 may be provided that connects wall-mounted track sections or wall- mounted track surfaces 33 between two walls.
- Wall transitioning track section 37 may include interlocking structures 26 at each end, at one end in combination with a ramp being formed at the other end of the section, or may be omitted with ramps instead being formed at each end of the track section, depending on whether wall- mounted track sections or wall-mounted track surfaces 33 are used.
- a potential advantage of the floor-to-wall and wall-to-wall configurations is that play with the toy vehicles 40 may be expanded, where a user may be able to route the track in other spatial extensions and move the toy vehicle 40 along a floor or wall continuously. This is in contrast to conventional tracks that are generally designed to be used only in one plane and thus lack the potential advantage of having many spatial configurations.
- track sections are disclosed herein, it will be understood that a variety of different accessory items (e.g., buildings, ramps/jumps, tunnels, stunt items such as loops or rings, or other simulated structures) may be included or used in conjunction with the disclosed track sections 14.
- a track section 14 may have an inclined surface portion inclined in a direction perpendicular to a flat upper surface of a flat track section at an angle of inclination b ranging from 10 degrees to 40 degrees to form a ramp 70, as shown in FIG. 12.
- a ramp 70 with this configuration having an angle of inclination b in the specified range may be appropriate for a ramp track section serving as an upward jump or a downhill coasting incline for toy vehicle 40.
- track sections 14 may be banked or curved in such a way as to increase frictional forces on a toy vehicle 40 that may be released from a user’s power while in motion, thus aiding in keeping the toy vehicle 40 from leaving the surface of the track sections 14.
- These accessory items may incorporate the same or similar interlocking structures 26 to interlock with the disclosed track sections, or may exclude the interlocking structures to be used alongside the track sections 14 without interlocking. Additionally, some track sections 14 may take the form of on-ramps or off-ramps that include interlocking structures 26 on a track interfacing side of that section to enable users to drive a toy vehicle from a floor or wall surface onto a track assembly or from the track assembly onto the floor or wall surface. Additionally, it will be understood that the various track sections 14 and/or accessory items disclosed herein may be packaged as one or more sets for purchase by consumers. These sets may include additional items that promote vehicle play, such as a stop watch, for example.
- the various implementations of track system 12 may have a number of potential advantages. Choosing an appropriate shape for the regular polygonal grid unit 20 may increase the potential for track layout configurations employed by a user.
- the thickness T of the track sections 14, shape of the interlocking structures 26, texture and“stickiness” of the EVA foam, and precision of the track geometry may help prevent the track sections 14 from becoming unintentionally disconnected during play, provide deformable and cushioning track material favorable to play, maintain sturdiness under stress during use, and be durable over many active play sessions, particularly with regard to the interlocking structures (e.g., projections 66 and recesses 68) that may be otherwise prone to tearing.
- the interlocking structures e.g., projections 66 and recesses 68
- a thickness of track sections made from EVA foam may be approximately 3/8 inch to approximately 1/2 inch as measured from the vehicle surface of the track to the underside of the track.
- the EVA foam may be of the same or greater density as typical children’s play mats and/or of the same or lesser density as typical industrial floor tiles.

DETAILED DESCRIPTION
[0019] A toy vehicle track system 12 comprising a plurality of track sections 14 is provided. FIG. 1 illustrates one example implementation of the toy vehicle track system 12. In this implementation, a plurahty of track sections 14 are connected to form a continuous track on which toy vehicles 40 may be guided. A toy vehicle 40 shown on the track system 12 may be guided along the track by a user via hand power, finger driving, or similar modes of propulsion, as well as downhill coasting along inclined portions of the track in which the vehicle may be released by the user. Several types of track sections 14 are shown in FIG. 1 and detailed in FIGS. 2-4 and FIGS. 5A-5C. Each track section 14 may have at least two terminal ends 24, although it will be appreciated that in other configurations a track section 14 may have only a single terminal end 24. Types of track sections 14 may include at least a straight track section 28 as shown in FIG. 2, a curved track section 30 as shown in FIG. 3, a Y-shaped track section 32 as shown in FIG. 4, transitioning track sections 36 as shown in FIGS. 11A, 11B and 12, and a U- shaped track section 39 as shown in FIGS. 11B. It will be appreciated that other
configurations of track sections 14 may be possible, including X-shaped track sections 62, r-shaped track sections 64, track sections that feature jumps or ramps, and other geometries with one or more terminal ends 24. An example implementation of an X-shaped track section 62 is shown in FIG. 5A; an example of an r-shaped track section 64 is shown in FIG. 5B. FIG. 5C depicts two r-shaped track sections 64 connected to a Y-shaped track section 32 at a portion of a track in a connected state.
[0020] FIG. 6 illustrates a geometric configuration of the track sections 14 according to one example implementation. In this implementation, the construction of the track sections 14 is executed to secure precise and tight connection between the track sections 14 and to increase the number of connection permutations possible with a finite number of track sections 14. These qualities are included among the potential advantages of the example implementation. Each track section 14 may be formed within a section of a regular polygonal grid unit 20 belonging to a regular polygonal grid 34, the track section 14 having at least two terminal ends 24 at edges 22 of the regular polygonal grid unit 20. It will be appreciated that the polygonal grid units 20 and the polygonal grid 34 are mathematical objects, and as such, represent idealized geometries. Thus, they are virtual rather than physical in nature. A U-shaped track section 39 may include the sections of a plurality of the regular polygonal grid units 20. For example, the U-shaped track section 39 may be formed by continuously joining three curved track sections 30, which may take the form of the U-shaped track section 39 as shown in FIG. 11B.
[0021] One potential advantage of this configuration, in addition to those described above, is a regular pattern of connection between track sections 14 that, being geometrically precise, aids in holding the track sections 14 together in the completed track. This feature is particularly important given the stress to which the track may be exposed during repeated assembly/disassembly and play. Additionally, this configuration featuring sections of regular polygonal grid units 20 belonging to a regular polygonal grid 34 may assist younger children in being successful at constructing multi-section track assemblies due to the regular patterning of connections between track sections 14.
[0022] As shown in FIG. 6, a width W of the straight track section 30 may be in a range of 5 inches to 6 inches and a length L of the straight track section 30 may be in a range of 11 inches to 12 inches. In one example, the width W may be 5.75 inches and the length L may be 11.6 inches. Dimensions of the regular polygonal grid unit 20 are also indicated in FIG. 6. In the example implementation shown in FIG. 6, a hexagon that is the regular polygonal grid unit 20 belonging to the regular polygonal grid 34 having a hexagonal pattern may have a length along one side S in a range of 6 inches to 7 inches, a length between two opposite sides SS in a range of 11 inches to 12 inches, and a length between two opposite corners CC in a range of 13 inches to 14 inches. In another example, the length along one side S may be 6.75 inches, the length between two opposite sides SS may be 11.6 inches, and a length between two opposite corners CC may be 13.5 inches. It will be appreciated that other dimensions are also possible as these values are merely exemplary.
[0023] The terminal ends 24 of each track section 14 may include interlocking structures 26 (e.g., projections 66 and recesses 68) that interlock with the interlocking structures 26 of at least a second track section 18. This is shown, for example, in FIG. 6 between the curved track section 30, which is a first track section 16 in this example, and the straight track section 28, which is the second track section 18 in this example.
[0024] Each track section 14 may be at least partially or entirely composed of foam. One potential advantage of such a configuration is that the track sections 14 may be deformable and unlikely to produce injury to a user should impact between the user and the track sections 14 occur, whether during track construction, play, or inadvertently when a user moves around or over the track. In a preferred configuration, the foam is ethylene -vinyl acetate (EVA) foam. The use of this particular material has at least several potential advantages. The texture of EVA foam is such that the track may be sturdy and endure under repeated stress and wear, while also being deformable and less likely to cause injury compared to rigid toy car track materials including hard plastics. The track sections 14 may be placed on various surfaces such as wood, carpet, etc., as EVA foam exhibits a high adhesion to many types of flooring. EVA foam texture and surfaces may also be advantageous in that friction forces between the toy vehicle 40 and the track may be optimal for propulsion of the toy vehicle 40 along the track. A“stickiness” inherent in EVA foam may work in favor of adhering the track sections 14 to each other at the connection areas of the interlocking structures 26. Track sections 14 may therefore be less likely to separate during
play. Additionally, EVA foam is inexpensive to manufacture, decorate, and die cut into desired shapes.
[0025] It will be appreciated that although a hexagonal grid as shown in FIG. 6 is a preferred implementation for constructing the track sections 14 from a regular polygonal grid 34, the regular polygonal grid unit 20 may belong to a regular polygonal grid 34 having a pattern of hexagonal, rectilinear, or triangular, to name a few example implementations as shown in FIGS. 7A-7C. It will be appreciated that other regular polygonal grids 34 may be implemented, such as those with multiple types of regular polygons and vertices or tiling patterns, as advantageous for track design or inventive play. Freeform designs may also be employed, or combinations of regular and freeform constructions.
[0026] FIG. 8 is a perspective of a straight track section 28. The perspective shows a side of the track section 14 with a thickness T. In a preferred implementation where the track section 14 is EVA foam, the EVA foam may have a thickness T in a range of 3/8 inches to 1/2 inches. Also, the EVA foam may be textured on at least one surface of the track section 14. The straight track section 28 as shown in FIG. 8 is one example implementation of a track section 14 where texturing simulates the presence of rock protrusions in the track section 14. Texturing of the track sections 14 may have at least one potential advantage of increasing types of play with a toy vehicle 40 on the track system 12.
[0027] Track sections 14 may additionally include banked track sections 58 having banked curves 60 as shown in FIG. 13. Banked curves 60 and texturing may be employed to create different simulated road conditions during play with a toy vehicle 40 along the track system 12. In one example implementation, the
track sections 14 may be designed to simulate an asphalt or concrete surface of a street environment or a race-track environment. In the case of simulated street environments, track sections 14 may include markings, texturing, and/or signage typical of city streets or other public roadways. In the case of simulated race tracks, track sections 14 may include such banked curves 60 and/or markings indicative of professional race-track environments. As another example, the track sections 14 may be designed to simulate a dirt or mud track, including a variety of protrusions, indentations, texturing, and the like. Track sections 14 with different types of texturing and design may be connected to each other; for example, a dirt- track section 72 may be connected to a race-track section 74 that may be connected to an off-road type track section 76 having simulated rock protrusions as shown in FIG. 15. The user may engage with the track system 12 by exercising a choice in the connection of track sections 14 to each other, thus possibly increasing a potential for play.
[0028] The interlocking structures 26 may connect at least a first track section 16 with at least a second track section 18 to form a dovetail joint 38. This type of connection is depicted in FIG. 9. For the straight track sections 28 and curved track sections 30 as viewed from above a top side 50, such as those in FIGS. 2 and 3, respectively, a projection 66 of the dovetail joint 38 may extend from a distal end of a right-end short edge of each track section and a recess 68 of the dovetail joint 38 may extend from a distal end of a left-end short edge of each track section 14. In this configuration the interlocking structures 26 may interface interchangeably when oriented with the top side 50 up. One potential advantage of this configuration is that the track sections 14 may be secured to each other
sufficiently to endure stress during play and hold together while the track is being used, yet still be easily assembled and disassembled. Furthermore, lane indicators 52 may be included on the top surface of the top side 50 of each track section 14 to indicate at least two lanes 54, 56 on each track section 14 as shown in FIGS. 2-4. In this configuration, the projections 66 of the dovetail joints 38 may extend once per indicated lane of the at least two lanes 54, 56 of each track section 14. Although dovetail joints are illustrated, other types of interlocking joints may be used, such as a dowel joint, finger joint, tongue and groove joint, dado joint, mortise and tenon joint, or bridle joint.
[0029] The potential advantages of the configurations described may include a great variety of play options with the toy vehicle track system 12. By taking advantage of the choice of regular polygonal gird 34, not only may secure and precise connections be possible, but the diversity of track layouts when the track sections 14 are in a connected state may be very large. Thus, forming the track in a connected state with available track sections 14 may become one feature of potential play with the track system 12. FIGS. 10A- 10C illustrate several possible track layouts using a 20 -piece track section kit. As may be seen, forming the various track layouts presents a user with a variety of choices, expanding a potential for interaction and play with the track system 12. Building the track into a connected state may become part of the interactive experience with track system 12 in addition to use of the track system 12 with toy vehicles 40. Also, interaction between multiple users may be encouraged by the possibility for many track layouts, involving cooperation and decision making not only for a track layout design but planning for advantageous use with the toy vehicles 40. It will
be appreciated that a track system 12 may not be limited to 20 pieces, as shown in FIGS. 14 and 15.
[0030] Turning to FIGS. 11A and 11B, in addition to the configurations described above, the track system 12 may be constructed to include transitioning track sections 36 curved in a direction perpendicular to a flat upper surface of a flat track section. The transitioning track sections 36 may be configured to connect at least a first track section 16 at an angle «relative to at least the second track section 18, where the angle «may be 90 degrees. This may be advantageous when the track system 12 includes at least one track section 14 that is a wall-mounted track section. In one implementation, a first wall-mounted track section 42 may be connected to at least one floor track section 46, the first wall-mounted track section 42 and the floor track section 46 connected via at least one transitioning track section 36. Similarly, a first wall-mounted track section 42 may be connected to at least a second wall-mounted track section 44, the first wall-mounted track section 42 and the second wall-mounted track section 44 connected via at least one transitioning track section 36. In such implementations, the transitioning track sections 36 may be designed for routing the track from floor-based track sections to wall-mounted track sections or a wall-mounted track surface 33, as shown in FIGS. 11A- 11B. The transitioning track section 36 may connect at least a floor- based track section at an angle a relative to either a wall-mounted track section (depicted in FIG. 11B as a U-shape track section 39) or a wall-mounted track surface 33 (e.g., depicted in FIG. 11A). In at least some implementations, transitioning track section 36 may include a rear cutout section that
accommodates baseboard trim as may be found in a typical home environment (e.g., as depicted in FIGS. 11A and 12 for the right-hand track section 36).
[0031] As a first example depicted in FIG. 11A, a wall-mounted track surface
33 may be mounted to a wall and a user may operate a toy vehicle 40 on the wall- mounted track surface 33. Wall-mounted track surface 33 may take the form of a contiguous sheet of material upon which a track graphic is printed or otherwise visually depicted. In at least some implementations, TYVEK may be used as the material for the wall-mounted track surface 33 due to its properties as being lightweight, non -stretching, and durable. For example, the SOFT STRUCTURE or“soft hand” form of TYVEK may provide the advantage of not wrinkling when folded, rolled, or compressed for storage, thereby ensuring smooth track surfaces for vehicle play. Where wall-mounted track surface 33 is used, transitioning track section 36 may include a first end (e.g., the floor side) having interlocking structures 26 that interface with interlocking structures 26 of a floor-based track section (e.g., first track section 16), and a second end (e.g., the wall side) that forms a ramp that interfaces with the wall-mounted track surface 33 to provide a smooth transition between the floor-based track section and the wall-mounted track surface 33.
[0032] As an additional example, FIG. 11B depicts the use of wall-mounted track sections in which any of the previously described track sections may be wall- mounted to enable vehicle play on both vertical and horizontal surfaces. For example, a U-shaped track section 39 and transitioning track sections 36 may include interlocking structures 26 at each end to form a track assembly that spans floor and wall surfaces. Where wall-mounted track sections are used,
transitioning track section 36 may include a first end (e.g., the floor side) having interlocking structures 26 that interface with interlocking structures 26 of a floor- based track section, and a second end (e.g., the wall side) having interlocking structures 26 that interface with interlocking structures 26 of a wall-mounted track section (e.g., U-shaped track section 39).
[0033] In at least some implementations, a semi-permanent adhesive may be used to secure wall-mounted track surface 33 or wall-mounted track sections to a wall. As an example, BLUESTIK reusable adhesive putty may be used to secure track sections to a wall. However, it will be understood that other suitable adhesives may be used including semi-permanent and permanent adhesives.
[0034] As further shown in FIGS. 11A and 12, wall transitioning track section 37 may be provided that connects wall-mounted track sections or wall- mounted track surfaces 33 between two walls. Wall transitioning track section 37 may include interlocking structures 26 at each end, at one end in combination with a ramp being formed at the other end of the section, or may be omitted with ramps instead being formed at each end of the track section, depending on whether wall- mounted track sections or wall-mounted track surfaces 33 are used.
[0035] A potential advantage of the floor-to-wall and wall-to-wall configurations is that play with the toy vehicles 40 may be expanded, where a user may be able to route the track in other spatial extensions and move the toy vehicle 40 along a floor or wall continuously. This is in contrast to conventional tracks that are generally designed to be used only in one plane and thus lack the potential advantage of having many spatial configurations.
[0036] While a variety of track sections are disclosed herein, it will be understood that a variety of different accessory items (e.g., buildings, ramps/jumps, tunnels, stunt items such as loops or rings, or other simulated structures) may be included or used in conjunction with the disclosed track sections 14. For example, a track section 14 may have an inclined surface portion inclined in a direction perpendicular to a flat upper surface of a flat track section at an angle of inclination b ranging from 10 degrees to 40 degrees to form a ramp 70, as shown in FIG. 12. A ramp 70 with this configuration having an angle of inclination b in the specified range may be appropriate for a ramp track section serving as an upward jump or a downhill coasting incline for toy vehicle 40. Thus, track sections 14 may be banked or curved in such a way as to increase frictional forces on a toy vehicle 40 that may be released from a user’s power while in motion, thus aiding in keeping the toy vehicle 40 from leaving the surface of the track sections 14.
[0037] These accessory items may incorporate the same or similar interlocking structures 26 to interlock with the disclosed track sections, or may exclude the interlocking structures to be used alongside the track sections 14 without interlocking. Additionally, some track sections 14 may take the form of on-ramps or off-ramps that include interlocking structures 26 on a track interfacing side of that section to enable users to drive a toy vehicle from a floor or wall surface onto a track assembly or from the track assembly onto the floor or wall surface. Additionally, it will be understood that the various track sections 14 and/or accessory items disclosed herein may be packaged as one or more sets for
purchase by consumers. These sets may include additional items that promote vehicle play, such as a stop watch, for example.
[0038] As discussed above, the various implementations of track system 12 may have a number of potential advantages. Choosing an appropriate shape for the regular polygonal grid unit 20 may increase the potential for track layout configurations employed by a user. The thickness T of the track sections 14, shape of the interlocking structures 26, texture and“stickiness” of the EVA foam, and precision of the track geometry may help prevent the track sections 14 from becoming unintentionally disconnected during play, provide deformable and cushioning track material favorable to play, maintain sturdiness under stress during use, and be durable over many active play sessions, particularly with regard to the interlocking structures (e.g., projections 66 and recesses 68) that may be otherwise prone to tearing. As an example, a thickness of track sections made from EVA foam may be approximately 3/8 inch to approximately 1/2 inch as measured from the vehicle surface of the track to the underside of the track. In at least some implementations, the EVA foam may be of the same or greater density as typical children’s play mats and/or of the same or lesser density as typical industrial floor tiles. Forming the track in a connected state and using the track with toy vehicles 40 may encourage a variety of problem solving and play for a user as well as interaction between multiple users in planning, design, and play. As the described configuration is also potentially advantageous for adult-child interactive time, it may be less likely to be distracting for or injurious to children or adults given its deformabihty and ease of construction, thus enhancing the quality of interaction time.
[0039] It is to be understood that the various embodiments and implementations described herein are exemplary in nature, and that these examples are not to be considered in a limiting sense, because numerous variations are possible. The subject matter of the present disclosure includes all novel and nonobvious combinations and sub -combinations of the various embodiments and implementations, and other features, configurations, functions, acts, and/or properties disclosed herein, as well as any and all equivalents thereof. It should be understood that the disclosed embodiments and implementations are illustrative and not restrictive. Variations to the disclosed embodiments and implementations that fall within the metes and bounds of the claims, now or later presented, or the equivalence of such metes and bounds are embraced by the claims.
