Description

FIELD

[0001] The present patent document relates to improved chassis for toy vehicles and methods of making the same. In particular, the present patent document relates to chassis for toy vehicles that allow articulation of the axles and accordingly the wheels of the toy vehicle.BACKGROUND

[0002] Toy vehicles have long been popular collectibles, both as play objects for children and as display pieces for hobbyists. Many of these vehicles are designed to replicate the appearance of real automobiles, trucks, construction equipment, or other specialty vehicles, and often include details such as painted bodies, decorative chassis, or functional wheels to enhance realism.

[0003] Conventional toy vehicles typically employ rigid chassis structures in which the axles are mounted in fixed relation to the body of the vehicle. While such constructions allow the vehicles to roll, they generally lack the ability to simulate more realistic vehicular dynamics, or pose the vehicles in more complex poses. In particular, there is a large community of car enthusiasts that like customizing their cars such that they can change the height of the body of the car with respect to the ground. These cars are sometimes referred to as low-riders and can have fixed suspension or suspensions that use hydraulics such that the ride height may be customized at any time. The wheels and axles of conventional toy vehicles remain fixed, which can reduce realism and limit the range of play value.

[0004] Some designs have attempted to improve functionality by incorporating suspension features or flexible components. However, these approaches are often complex, costly to manufacture at scale, or unsuitable for small collectible formats. As a result, most collectible toy vehicles continue to rely on simple fixed-axle designs that fail to capture the dynamic articulation of real-world vehicles and custom vehicles with custom suspensions.

[0005] Accordingly, there remains a need for toy vehicle chassis structures that permit articulation of the axles and / or wheels relative to the body of the vehicle. Such improvements would enhance realism, increase play value, and provide a distinguishing feature for collectible toy vehicles, without unduly increasing complexity or cost of manufacture.SUMMARY OF THE EMBODIMENTS

[0006] Objects of the present patent document are to provide a various different chassis for a toy vehicle that allow for novel and unique play patterns. In some embodiments, a chassis for a toy vehicle is provided, comprising a body having a series of circular holes extending horizontally through a front portion of the body and vertically aligned such that each hole partially overlaps an adjacent hole, defining a continuous vertical column with scalloped sides. Similarly, a second plurality of circular holes extends horizontally through a rear portion of the body, arranged vertically so that each hole partially overlaps the next, forming a second continuous vertical column with scalloped sides. The holes are sized to allow the axle to rotate and be retained within each hole but forced between holes to allow different axle configurations.

[0007] According to one aspect of the invention, each circular hole in the first plurality of circular holes and the second plurality of circular holes may be sized to retain an axle. In another embodiment, each circular hole in the first plurality of circular holes overlaps such that opposing peaks of the scalloped sides form first gaps that are smaller than a radius of a circular hole in the first plurality of circular holes. In certain embodiments, the first gaps are sized slightly smaller than an axle diameter such that the axle only passes through when forced. In some configurations, the first gaps include flat sides to provide improved axle retention and stability.

[0008] According to another aspect, each circular hole in the second plurality of circular holes overlaps such that opposing peaks of the scalloped sides form second gaps that are smaller than a radius of a circular hole in the second plurality of circular holes. The second gaps may also be sized slightly smaller than an axle diameter such that the axle only passes through when forced. In some embodiments, the second gaps include flat sides similar to those of the first gaps to enhance secure axle positioning.

[0009] In yet another embodiment, the body of the chassis further comprises a front, back, and middle horizontal support structure, each spanning the width of the chassis body. In some embodiments, one or more through holes extend vertically through the body, allowing the chassis to be coupled to a vehicle body using one or more fasteners.

[0010] According to still another aspect, the first plurality of circular holes passes horizontally through a left front sidewall of the body and a right front sidewall of the body. In such embodiments, the left and right front sidewalls are thicker than the surrounding wall portions where the first plurality of circular holes passes horizontally through. Similarly, in other embodiments, the second plurality of circular holes passes horizontally through a left back sidewall of the body and a right back sidewall of the body. The left and right back sidewalls may also be thicker than the surrounding wall portions where the second plurality of circular holes passes horizontally through, providing additional strength and support to the rear portion of the chassis.

[0011] In yet another embodiment, another chassis for a toy vehicle is disclosed. The chassis includes a body having front, back, top, and bottom portions, and a central structural member extending horizontally across the body. A pivot axis is located within the central structural member. A first articulating arm is pivotally connected to the body at the pivot axis and extends forward to a distal end configured to receive a first axle. A second articulating arm is connected to the body at a second proximal end by a ball-and-socket joint and extends rearward to a distal end configured to receive a second axle. This arrangement allows for controlled articulation of the arms to enhance the movement and suspension characteristics of the toy vehicle.

[0012] According to one embodiment of the invention, the chassis may further comprise a third articulating arm having a third proximal end pivotally coupled to the body at the pivot axis and extending toward the front of the body to a third distal end configured to receive a third axle.

[0013] In another embodiment, the ball and socket joint is positioned forward of the central structural member to provide enhanced articulation and structural balance within the chassis. In yet another embodiment, the second articulating arm has the shape of an isosceles triangle with a tip at the second proximal end and a base at the second distal end. In certain embodiments, the base of the isosceles triangle is configured to receive the second axle parallel to the base, thereby facilitating stable axle alignment and improved vehicle performance.

[0014] According to another aspect of the invention, the body further comprises a front bumper and a rear bumper, providing added protection and structural reinforcement to the toy vehicle chassis.

[0015] In some embodiments, where the chassis includes a third articulating arm, the first articulating arm and the third articulating arm are coupled to the pivot axis on either side of the ball and socket joint. Each of the first and third articulating arms may include a first elbow that bends inward toward a centerline of the body and a second elbow that bends back toward the front of the body, thereby enhancing range of motion and suspension responsiveness.

[0016] In yet another embodiment, the chassis further comprises a light coupled to the top of the body and in electrical communication with a switch located on the bottom of the body. This configuration enables selective illumination during operation of the toy vehicle, providing both aesthetic and functional benefits.

[0017] In yet another embodiment, a chassis for a toy vehicle configured to be a fidget toy is disclosed. The chassis includes a body having front, back, top, and bottom portions, and a pivot axis positioned within the body. A first articulating arm is pivotally connected to the body at the pivot axis and extends forward to a distal end configured to receive a first axle. A spring is coupled between the body and the first articulating arm to bias the distal end of the arm away from the body, providing resilient movement. A second articulating arm is connected to the body at a proximal end by a ball-and-socket joint and extends rearward to a distal end configured to receive a second axle. This configuration creates a spring loaded front portion of the chassis that can transform the toy vehicle into a fidget toy.

[0018] According to one embodiment of the invention, the first proximal end of the first articulating arm forks into two portions that each couple to the pivot axis. This configuration provides additional stability and balanced articulation about the pivot axis.

[0019] In another embodiment, the second articulating arm has the shape of an isosceles triangle with a tip at the second proximal end and a base at the second distal end. In certain embodiments, the base of the isosceles triangle is configured to receive the second axle parallel to the base, allowing for improved alignment and uniform support of the axle.

[0020] According to another aspect of the invention, the chassis further comprises a rear axle extension coupled to the second distal end of the second articulating arm at a rear axle extension first proximal end. The rear axle extension includes at least one location aft of the second distal end configured to receive the second axle. In some embodiments, the rear axle extension has a rear axle extension first distal end that extends past the back and above the body and terminates in a platform, which may serve as a mounting or attachment surface. In yet another embodiment, the rear axle extension comprises multiple locations aft of the second distal end configured to receive the second axle, providing flexibility in positioning the axle to alter the wheelbase or adjust the vehicle’s stance.

[0021] In some embodiments, a first spring end is coupled to the bottom of the body toward the front, and a second spring end opposite the first spring end is coupled to a topside of the first distal end, wherein the spring extends along a centerline of the body. This configuration provides balanced spring tension and enhances the suspension response of the chassis.

[0022] In yet another embodiment, the chassis further comprises a light coupled to the top of the body and in electrical communication with a switch located on the bottom of the body, enabling selective illumination during operation of the toy vehicle.BRIEF DESCRIPTION OF THE DRAWINGS

[0042] FIG. 1 illustrates an isometric view of a chassis 10 for a toy vehicle. The chassis 10 comprises a body 11 and one or more axle-receiving holes 12 configured to support and retain the axles of the toy vehicle. The holes 12 pass horizontally through the body 11 such that they can support an axle in a typical orientation. Each hole 12 is part of a vertically aligned series of generally circular apertures arranged in a column 20 on the side wall 14 of the chassis 10. The apertures extend through the side wall 14 and are sized to permit selective placement of an axle therethrough.

[0043] As may be appreciated, a first plurality of circular holes 12 passing horizontally through a front portion of the body 11 are present to support a front axle. A second plurality of circular holes 12 passing horizontally through a back portion of the body 11 are present to support a rear axle.

[0044] In the embodiment shown, four vertically stacked apertures are provided. Each hole in the plurality of holes partially overlaps with the next adjacent hole to form a continuous through column with scalloped sides. The continuous through column of holes allows the axle to be mounted in four distinct vertical positions relative to the chassis body. By selecting one of these apertures, the ride height, wheel clearance, or articulation characteristics of the vehicle can be varied.

[0045] The relative location of the centers of the apertures are spaced apart less that a full diameter of one hole such that the circumferences of adjacent holes overlap. In preferred embodiments, the centers of the holes are spaced apart between 80% and 99% of the diameter of the hole. In more preferred embodiments, the centers of the holes are spaced apart between 80% and 90% of the diameter of the hole. This overlapping arrangement creates a continuous vertical column of potential axle positions, while still defining discrete seating positions where the axle can be stably retained. The overlapping holes create continuous vertical through columns with scalloped sides. The holes overlap such that opposing peeks of the scalloped sides form gaps 16 that are smaller than a radius of one of the circular holes.

[0046] The holes are sized to retain an axle. The gaps 16 between adjacent apertures is dimensioned so that the axle cannot freely or inadvertently pass between positions during normal play. However, the gap is sufficiently small that the axle may be manually urged or pushed by the user from one aperture to another when it is desired to reposition the axle. This arrangement provides a balance between secure retention and user-adjustability.

[0047] In other embodiments, a different number of apertures may be employed. For instance, two or three apertures may provide limited adjustment, while five or more apertures may allow for finer increments of axle positioning. The size, spacing, and degree of overlap of the apertures can also be varied according to the desired level of customization, scale of the toy vehicle, or manufacturing considerations.

[0048] The apertures 12 are preferably dimensioned to closely receive the axle shaft while still permitting free rotational movement of the wheels mounted thereon. In certain embodiments, the apertures 12 may also cooperate with other chassis features—such as recesses, slots, or flexible supports—to permit pivoting or rocking articulation of the axle within the chassis. This articulation enhances realism by more closely replicating the suspension dynamics of full-sized vehicles.

[0049] As may be seen in FIG. 4, the sidewalls 18 of the gaps 16 may be flat. In other embodiments, other shapes for the sidewalls of the gaps may be used.

[0050] The vertically aligned series of generally circular apertures arranged in a column 20 are configured to pass entirely through the chassis structure 10. In some embodiments, the apertures are formed directly through the body of the chassis, such that the axle may be inserted and supported within the chassis body itself. In other embodiments, the apertures are provided in sidewalls positioned adjacent to each wheel, with corresponding columns of apertures on opposite sides of the chassis. In this arrangement, the axle extends across the vehicle and is supported at its ends by apertures in the opposing sidewalls.

[0051] In embodiments where the apertures are provided in sidewalls, the apertures pass through a front right, front left, rear right and rear left sidewall. In preferred embodiments, the sidewalls may be bossed or thicker in the location the apertures pass through. The bossed out sidewall provides additional support for the axles.

[0052] The chassis further includes one or more fastener-receiving holes 22 that extend from the bottom surface of the chassis through to the top surface. Each hole 22 is sized and shaped to receive a fastener, such as a screw, pin, or other removeable fastener thereby enabling the chassis to be removably connected to the body of the toy vehicle.

[0053] In use, a fastener inserted through the hole 22 passes completely through the chassis and engages a corresponding feature of the vehicle body, such as a threaded boss, snap-fit receptacle, or mating aperture. This arrangement permits the chassis to be securely attached during play, while still allowing disassembly for maintenance, reconfiguration, or replacement of parts.

[0054] In certain embodiments, a plurality of fastener holes 22 may be distributed along the chassis to provide stable attachment at multiple points, while in other embodiments a single central fastener hole may be sufficient. The number, placement, and sizing of the holes may be varied according to the scale of the toy vehicle and the type of fastener used. In the embodiments shown, two fastener holes 22 are used, one near each end of the vehicle.

[0055] The chassis may further include a plurality of structural members 32, 34, and 36 that extend horizontally across substantially the full width of the chassis body. In the embodiment shown, three such members 32, 34, and 36 are provided.

[0056] Each of these structural members spans laterally between opposing sides of the chassis, thereby functioning as cross-braces that increase the overall strength and rigidity of the chassis assembly. By extending across the full width, the members resist torsional twisting and bending loads that may occur during play, while also providing stable anchoring points for other chassis features.

[0057] In the illustrated embodiment, member 32 is positioned toward the forward portion of the chassis, member 34 is located centrally, and member 36 is located toward the rear. This arrangement distributes support along the length of the chassis and contributes to the durability of the component under repeated use.

[0058] In alternative embodiments, the number, placement, or configuration of the structural members may be varied. For example, two cross-members may be sufficient in smaller-scale vehicles, while additional members may be incorporated in larger-scale or more complex vehicles. The structural members may also include integrally formed features such as mounting apertures, reinforcement ribs, or connection points for additional components.

[0059] FIG. 15 illustrates a top-down view of another embodiment of a chassis 100 for a toy vehicle. The embodiment shown in FIG. 15 differs from the embodiments in FIGS. 1-14 because the toy vehicle includes a chassis 100 that supports a front wheel assembly configured for independent articulation. The front wheels are mounted on articulating arms 102, each of which is pivotally connected to the chassis 100.

[0060] The body has a front 101, back 103, top 105 and bottom 107.

[0061] Each articulating arm 102 is supported to pivot about a pivot axis 106. In the embodiment shown, the pivot axis 106 is coupled to the chassis 100 via an internal axle 108 that spans laterally across the central portion of the chassis 100. In the embodiments shown, the internal axis runs through the central structural member 34. Both articulating arms 102 are mounted to this internal axle 108, thereby permitting rotation of each arm relative to the chassis structure.

[0062] At the distal end of each articulating arm 102, a fastener-receiving hole is provided for mounting of an independent wheel axle 104. Each wheel axle 104 extends outwardly from the articulating arm and supports a corresponding wheel. This arrangement permits each wheel to be carried on its own axle, rather than requiring a common axle spanning the full width of the chassis.

[0063] As mounted, each articulating arm 102 can pivot about the pivot axis 106 to allow the wheel and its corresponding axle 104 to rotate downward away from the chassis 100. The independent pivoting action allows the left and right front wheels to move separately, providing greater articulation and more realistic suspension-like movement. Although the embodiments shown in FIG. 15 illustrates this independent articulating wheel design for the front wheels, in other embodiments this design may be used for the front, wheels rear wheels or independently for any particular wheel.

[0064] In the embodiment shown, the pivot axis 106 is realized as a transverse axle 108 extending across the chassis 100, with each articulating arm 102 rotatably mounted thereto. In alternative embodiments, each articulating arm may be pivotally connected by separate pins or molded hinge features, rather than sharing a single transverse axle.

[0065] This configuration enhances the realism and play value of the toy vehicle by permitting independent movement and positioning of the front wheels, simulating the suspension and articulation found in full-sized vehicles or simulating custom vehicles that include hydraulic suspensions.

[0066] In another embodiment, not shown, the two articulating arms 102 are each provided with a hole that is aligned laterally across the chassis, such that a single common axle may extend through both arms to support both front wheels. In this configuration, the wheels share a common axle spanning between the arms, while the arms themselves continue to pivot about the pivot axis 106.

[0067] This arrangement prevents the independent articulation of the wheels but simplifies construction by eliminating the need for separate axles for each wheel. The shared axle may be removably mounted or integrally retained within the arms, depending on manufacturing requirements.

[0068] In the embodiment shown in FIG. 15, each articulating arm 102 is an elongated member that extends laterally outward from the pivot axis 106 toward the corresponding wheel location. In the embodiments shown, the arms 102 have a step inward towards the center of the vehicle but in other embodiments, the arms may be straight. The arms 102 are bar-like in form, providing a rigid structure between the pivot point and the wheel axle.

[0069] At the proximal end, each arm 102 has a mounting region configured to receive the pivot axis 106, allowing the arm to couple to the pivot axis 106 and rotate relative to the chassis 100. This region may be formed as a cylindrical bore or socket through which the pivot axis 106 passes. In preferred embodiments, the arm 102 is coupled to the pivot axis 106 with sufficient friction to allow the arm to remain in whatever position it is articulated into under the weight of the chassis and mounted body of the vehicle. In other embodiments, the arms 102 may have specific positions they lock into. This may be accomplished with dimples and corresponding bumps or by using other known positional stability techniques.

[0070] The intermediate portion of each arm is narrow and elongated, projecting outwardly from the chassis body. This portion provides clearance beneath the chassis while maintaining sufficient strength to support the wheel.

[0071] At the distal end, each arm 102 is widened and includes a through-hole sized to receive either an independent axle 104 (in the embodiment shown) or a portion of a common axle shared with the opposite arm (in alternative embodiments). The distal hole is positioned to align the wheel axle parallel to the pivot axis, ensuring proper rotation of the wheel.

[0072] In the embodiment illustrated, the overall shape of each articulating arm 102 resembles a lever arm with a cylindrical mounting feature at the proximal end, a narrow extending bar portion, and a rounded distal end with an axle hole.

[0073] In alternative embodiments, the arms may incorporate reinforcement ribs, flanges, or tapering profiles to increase rigidity while minimizing material use. The arms may also be contoured or offset to provide additional clearance for wheels, chassis features, or body components.

[0074] In the embodiment shown in FIG. 15, the chassis 100 further supports a rear axle 112 and corresponding wheels, which are mounted to the distal end of an articulating arm 114. The articulating arm 114 is coupled to the chassis by way of a ball joint 110 received within a complementary socket formed in the chassis structure.

[0075] The ball joint 110 and socket interface enables the articulating arm 114, and thus the rear axle 112 and wheels carried at its distal end, to move through a full range of multi-directional motion relative to the chassis. In particular, the ball joint allows the rear axle 112 to: 1) Rotate downward and upward away from and toward the chassis 100, simulating suspension travel; 2) Rotate laterally or pivot side-to-side relative to the chassis, allowing the axle and wheels to articulate over uneven terrain or during cornering play; 3) Twist or yaw relative to the chassis, thereby providing realistic independent rotational articulation of the rear wheels with respect to the body of the toy vehicle.

[0076] This configuration provides a highly flexible and durable mounting for the rear wheels, allowing the posing of the vehicle in numerous configurations. The use of a ball joint 110 also allows independent articulation of the rear axle relative to the front axle assembly, enabling greater play value and variety of wheel positions during use.

[0077] In some embodiments, the ball joint 110 may be integrally molded with the articulating arm, while the socket is formed in the chassis 100. In other embodiments, the ball and socket may be reversed, or the joint may incorporate retention features such as clips, flanges, or detents to prevent unintentional separation while still permitting free articulation.

[0078] In preferred embodiments, the ball joint 110 has sufficient friction with the socket to allow the rear axle to maintain its position under the weight of the chassis and vehicle body once positioned.

[0079] The ball joint 110 is positioned on the chassis 100 just forward of the pivot axis 106 about which the front articulating arms 102 rotate. In the illustrated embodiment, the ball joint 110 is located generally along the longitudinal centerline of the chassis, between the two articulating arms 102.

[0080] This placement situates the ball joint in a central region of the chassis where it can provide stable support for the rear articulating arm and its mounted axle 112, while maintaining clearance for the independent operation of the front articulating arms 102. The forward positioning relative to the rear axle also allows the ball joint to act as a pivoting anchor point, enabling the rear wheels to articulate downward away from the chassis as well as to rotate relative to the chassis.

[0081] In alternative embodiments, the ball joint may be positioned at other locations along the chassis, but in the configuration shown, its placement just forward of the front axle pivot axis 106 and centrally between the articulating arms 102 provides a compact and efficient arrangement for supporting both front and rear wheel articulation within the same chassis structure.

[0082] In the illustrated embodiment, the rear articulating arm 114 extends rearwardly from the ball joint 110 and terminates at the rear axle 112, which supports the two rear wheels. The rear articulating arm 114 projects longitudinally from the ball joint toward the rear of the chassis 100. In the embodiment shown, the rear articulating arm 102 is generally triangular in shape and more particularly, shaped like an isosceles triangle with the ball joint 110 located at the tip of the triangle and the axis passing through the base of the triangle. In other embodiments, other shapes may be used.

[0083] The proximal end of the arm includes a spherical ball portion (ball joint 110) that is received in a complementary socket of the chassis, thereby permitting multi-directional articulation. The arm is generally flat allowing it to tuck into the bottom of the chassis to provide adequate clearance beneath the chassis body while maintaining strength and rigidity. At the distal end, the arm includes a transverse mounting region into which the rear axle 112 is fitted, allowing the wheels to rotate freely.

[0084] In another embodiment, the rear articulating arm may be configured in a forked or Y-shape rather than a triangle. In this design, the arm extends rearward from the ball joint 110 and then splits into two branches that diverge laterally. Each branch terminates in a wheel-mounting feature that directly supports one end of the axle 112 or even supports each wheel independently.

[0085] In some embodiments, the forward articulating arms 102 or the rear articulating arm 114 are configured to releasably hold their respective axle. Rather than being secured through a fully enclosed circular hole that permanently captures the axle, the distal end of the arm may terminate in a C-shaped or U-shaped receptacle. In this configuration, the axle can be pushed laterally into place or pulled outward without requiring disassembly of the entire chassis. The resilience of the arm material or added retention features may be used to hold the axle securely in normal use while still permitting intentional removal.

[0086] In other embodiments, the wheel itself may be releasably connected to the axle, for example through a press-fit, snap-fit, or keyed connection. This allows the user to remove one or more wheels from the axle first, after which the axle can be withdrawn from the arm receptacle.

[0087] By providing a selective retention mechanism for the axles and wheels, the toy vehicle is capable of further customization, enabling users to attach different wheel styles, sizes, or colors to the chassis. This enhances both play value and collectability, as users can interchange components to create personalized or themed vehicles.

[0088] In some embodiments, the chassis 100 includes one or more interface locations designed to selectively receive and secure one of the forward or rear articulating arms (102 or 114) in a fixed position relative to the chassis. These interface locations may take the form of recesses, detents, slots, or protrusions integrally formed in the chassis body.

[0089] When the articulating arm is moved into alignment with one of these interface locations, the distal or intermediate portion of the arm may be engaged and retained in place. Retention may be achieved by frictional fit, snap-fit engagement, or cooperation with a separate fastener. This arrangement allows the articulating arm, and any axle or wheel carried thereon, to be secured in a particular location.

[0090] In the fixed position, the articulating arm no longer pivots or rotates relative to the chassis, thereby providing a more rigid wheel support configuration. This feature can be useful, for example, when the toy vehicle is to be displayed as a collectible rather than actively played with, or when a more stable rolling condition is desired.

[0091] In alternative embodiments, multiple interface locations may be provided at different positions along the chassis, enabling the articulating arm to be secured at various fixed orientations. This allows the user to selectively configure the vehicle with the wheels lowered, raised, or angled, depending on the desired appearance or play condition.Lighting Systems

[0092] As may be seen in FIG. 15, in some embodiments, the chassis 100 is provided with an electrical switch 122 located on the bottom side of the chassis. The switch 122 is in electrical communication with one or more light sources 120 as shown in FIG. 16, such as light-emitting diodes (LEDs).

[0093] The light sources 120 are preferably positioned on the top side of the chassis, beneath the body of the toy vehicle when assembled. In this arrangement, the light sources are concealed from direct view, while still capable of projecting illumination. When activated by the switch 122, the light sources 120 direct light outward and downward to illuminate the underside of the chassis and the body shell of the vehicle.

[0094] This configuration produces a distinctive illumination effect commonly known as “ground effects” lighting, in which the toy vehicle appears to glow from beneath. Such effects enhance the realism and play value of the toy vehicle by replicating lighting modifications found in full-sized custom or performance vehicles.

[0095] In alternative embodiments, multiple light sources 120 may be distributed along the chassis to create more uniform illumination or to generate different lighting patterns. The switch 122 may be mechanical, electronic, or pressure-sensitive. The lighting system 120 is powered by a battery 124 integrated into the lighting system or chassis. In preferred embodiments, a wire 126 connects the lighting system 120 on the top side of the chassis to switch 122 on the bottom side of the chassis.

[0096] In an alternative embodiment, the lighting system of the chassis 100 further includes one or more light sources 120 positioned near the front portion of the chassis. These light sources are arranged such that, when the body of the toy vehicle is assembled to the chassis, the light shines through openings in the vehicle body that are shaped and positioned to simulate headlights.

[0097] The front light sources 120 may be implemented using LED elements and are preferably aligned with the simulated headlight features of the vehicle body, thereby enhancing realism by giving the appearance of functioning headlights.

[0098] The headlight light sources may be electrically connected to operate in conjunction with the ground effects lighting system, such that a single switch 122 controls all lights simultaneously. In other embodiments, the headlights and the ground effects lighting may be wired to separate switches, allowing independent operation. For example, the ground effects lights may be activated for stylistic display, while the headlights may be switched on to simulate normal vehicle driving conditions.

[0099] This arrangement further increases the play value and realism of the toy vehicle by replicating multiple types of lighting modifications commonly found in full-sized vehicles, including both underbody glow and forward-facing headlights.

[0100] In some embodiments, the chassis 100 further includes one or more rear-facing light sources 120 positioned near the back end of the chassis. These light sources are oriented such that, when the body of the toy vehicle is assembled, the lights shine through openings or transparent regions in the rear portion of the body that are shaped and positioned to simulate tail lights.

[0101] The rear-facing lights may be configured to operate as a pair, with one light on each lateral side of the chassis, to replicate the appearance of conventional automobile tail lights. The lights may be powered from the same power supply as other lighting elements on the chassis and may be controlled by either a shared switch 122 or a dedicated switch that allows independent operation.

[0102] In certain embodiments, the rear-facing lights may be configured to flash or pulse, either in response to switch activation or as part of a programmed lighting sequence. Such flashing or pulsing may simulate brake light operation or may be used purely for decorative effect, further enhancing the play and display value of the toy vehicle.

[0103] By incorporating rear-facing lights in addition to underbody “ground effects” lighting and forward-facing headlight simulation, the toy vehicle may provide a comprehensive lighting system that closely resembles the appearance and functionality of lighting systems in full-sized vehicles, while also enabling enhanced stylistic effects.

[0104] In preferred embodiments, the lights in the lighting system may be a fixed color. However, in some embodiments, the lighting system of the chassis 100 is configured to provide variable light colors, allowing the user to select or adjust the color of one or more light sources 120. The light sources may be implemented using multi-color LEDs (e.g., RGB LEDs) or through the use of interchangeable colored lenses or filters.

[0105] The lighting system may include a color-selection mechanism, such as a switch, dial, or electronic controller, that enables the user to choose from a range of available colors. In other embodiments, the lighting system may cycle through colors automatically, either in a programmed sequence or in response to user input. In other embodiments, a plurality of filters or lens may be provided that allow the user to customize colors by placing the filters in the appropriate location on the lighting system or chassis.

[0106] In some embodiments, the chassis 100 is formed from a colored material that is at least partially light-transmissive, such that light emitted from one or more light sources 120 passes through the chassis material. In this configuration, the color of the chassis material itself influences or even determines the perceived color of the ground-effects lighting.

[0107] For example, a chassis molded from a blue-tinted material will cause the ground-effects illumination to appear blue, while a chassis formed from a red-tinted material will cause the illumination to appear red. Users may therefore change the color of the ground-effects lighting simply by selecting and assembling a toy vehicle with a chassis of a different color.

[0108] This approach eliminates the need for variable-color light sources or filters while still allowing customization of the lighting effect. It also enhances the collectability of the toy vehicles, as different chassis colors can be offered as variations, each producing a distinct ground-effects illumination.

[0109] Preferably, the system may be arranged such that different types of lights replicate the colors commonly associated with full-sized vehicles. For example, tail lights are typically red or shades of red, providing a realistic appearance when illuminated through rear-facing openings in the body. Headlights are typically white or yellow or shades thereof, simulating the forward-facing headlights of an automobile. Ground effects lighting may be provided in any of a variety of colors, including blue, green, purple, or other stylistic hues, to enhance the decorative and play value of the vehicle.

[0110] By incorporating user-selectable or variable-color lighting, the toy vehicle can be customized to simulate real-world lighting functions or to create personalized display effects, further enhancing its appeal both as a play object and as a collectible item.Spring-Biased Articulating Arms

[0111] FIG. 18 illustrates a bottom up view of a chassis with a spring biased articulating arm holding the front axle. In the embodiment shown in FIG. 18, the forward articulating arms that support the front axle may be combined into a single forward articulating arm 202, as shown. The forward articulating arm 202 is pivotally mounted to the chassis 200 at axis 206 and is biased away from the chassis by a spring 204.

[0112] The biasing force applied by spring 204 determines the default position of the forward articulating arm 202 and thus, the default location of the front wheels relative to the chassis 200. The amount of bias can be adjusted through the length of the spring 204 in combination with the spring constant, thereby controlling how firmly or loosely the front wheels are urged away from the chassis 200.

[0113] In the embodiment shown, the spring 204 spans from the top side of the distal end of the front articulating arm 202 to the underside of the chassis 200 just behind the forward mounting hold 210.

[0114] This arrangement allows the front of the vehicle to be pressed downward against the bias of the spring 204 during play. When released, the spring causes the forward articulating arm 202 to spring or pop back to its default position. This action not only provides a visually dynamic effect but also enhances the tactile play value, effectively turning the toy vehicle into a form of fidget toy.

[0115] In alternative embodiments, the forward articulating arms are not combined into a single arm; instead, each articulating arm is independently biased relative to the chassis by its own spring. This configuration allows each wheel to move separately while still benefiting from spring-biased articulation.

[0116] In yet other embodiments, the rear articulating arm may be biased relative to the chassis with a spring, rather than the forward articulating arm. This provides similar visual and tactile effects but with articulation located at the rear of the vehicle. In yet other embodiments, both the forward and back articulating arms may be spring biased from the chassis.

[0117] In some embodiments, the rear axle and wheels may be removed and a rear axle extension 220 can be added in the place of the rear axle. The rear axle extension 220 is an additional part that has an axle replacement 212 that can be coupled to the chassis where the rear axle would normally go. The rear axle replacement further comprises a structure that allows the rear axle and accompanying wheels to be relocated to a new location on the rear axle extension 220.

[0118] As may be seen in FIG. 18, the rear axle extension 220 includes a forked shape arm that holds a rear axle substitute 212 that is designed to fit where the rear axle would attach to the chassis 200, in this case at the distal end of the rear articulating arm. The rear axle extension 220 comprises one or more places 214 to couple the rear axle that is farther aft of the original rear axle location. Accordingly, the rear axle extension can relocate the location of the rear axle in one or more directions.

[0119] As shown in FIG. 19, the chassis 200 may be fitted with a rear axle extension 220 in place of the original rear axle. The rear axle extension 220 includes a rear axle substitute 212, which is sized and configured to couple directly into the chassis 200 in the location normally occupied by the original rear axle. The substitute 212 thus serves as an anchoring interface, allowing the rear axle extension 220 to be removably attached to the chassis without requiring modification of the original chassis structure.

[0120] As shown in FIG. 18, the rear axle extension 220 further includes one or more mounting locations 214 configured to receive and secure the original rear axle. By seating the original rear axle into these mounting locations 214, the rear axle is effectively repositioned to a new, rearward location relative to the chassis 200, thereby "extending" the rear axle beyond its original position. This arrangement not only alters the geometry of the vehicle but also provides a novel appearance and play characteristic, similar to the extended frames and stylized modifications often found in custom vehicles.

[0121] In general, the rear axle extension may be any shape. In the embodiment shown in FIG. 19, the profile of the rear axle extension 220 includes a vertical member that protrudes upward into the bottom of the chassis 200 at the point of connection. This vertical member cooperates with the chassis to securely hold the extension in place while also providing a downward spacing between the body of the chassis 200 and the remainder of the rear axle extension 220. To this end, the rear axle extension 220 can not only extend the axle and wheels rearward, but can also provide additional vertical space between the rear axle and the body of the vehicle.

[0122] From the vertical member, the extension transitions into a rearwardly projecting member that supports the relocated axle mounting points. The geometry of the extension may be contoured to maintain wheel alignment and structural strength while minimizing added bulk.

[0123] The rear axle extension 220 further comprises a tail extension 217 that projects rearward beyond the relocated axle. At its distal end, the tail extension 217 terminates in a platform 216. This platform provides a convenient lever arm and surface for interaction by the user.

[0124] When the toy vehicle is used as a fidget toy, the user may press downward on the platform 216. This action transmits force through the tail extension 217 to the rear axle extension 220, causing the front end of the vehicle to bounce upward and downward. This feature is particularly useful in embodiments where the vehicle includes a spring-biased front suspension (as described previously), since pressing on the rear platform 216 accentuates the spring action at the front wheels.

[0125] The combination of the tail extension 217 and platform 216 thus enhances both the functional play value and tactile interactivity of the toy vehicle, allowing it to be manipulated in a manner that is engaging and entertaining for the user.
