Description

[0001] This application is a divisional application of the patent application with application number 2020800443198, application date April 21, 2020, and invention name “Powered Wheel Riding Device”. Technical Field

[0002] The present disclosure relates to the field of powered wheeled ride-on toys. Background Art

[0003] Wheeled riding toys, such as wheeled riding horses, are well known. In such toys, a child sits on a horse's saddle. The horse has wheels on all four legs, and the horse has a rigid internal frame for supporting the rider. The rider can then ride the horse and use her feet to push the horse around. While this may be fun for some people, users can easily become bored with toys that take this approach.

[0004] Two-wheeled self-balancing scooters, also often referred to as hoverboards, are also well known. A typical hoverboard includes a right portion and a left portion, each having a wheel and a foot pad. A user typically stands on the foot pads, and an electronic device such as a sensor detects the user's foot movement. A hoverboard controller directs control of the motors that drive the wheels based on such user input. Although popular, hoverboards have limited versatility. Summary of the invention

[0044] First refer to Figure 1A typical self-balancing scooter 30, commonly referred to as a hoverboard, includes a right portion 32 having a right wheel 34 and a right foot pad 36 and a left portion 42 having a left wheel 44 and a left foot pad 46. The user typically stands on the foot pads 36, 46. Electronic components, such as sensors, detect the user's foot movement. A scooter controller, including a microprocessor, receives a signal indicating such foot movement and directs control of the motors that drive the wheels based on such user input. For example, a user stands on the scooter 30, and if the user leans forward, the scooter is directed to move forward, and when the user leans backward, the scooter moves backward. In the illustrated embodiment, the relative right portion 32 and left portion 42 of the scooter 30 twist relative to each other based on the user's input to the right foot pad 36 and the left foot pad 46. For example, if the right portion 32 rotates forward and the left portion 42 rotates backward at the same time, the right wheel 34 will move forward and the left wheel 44 will move backward, so that the scooter 30 will turn and / or twist to the left (counterclockwise).

[0045] Refer to the following Figure 2 and Figure 3 In one embodiment, the two-wheeled self-balancing scooter 30 can be used in conjunction with a wheeled ride-on toy 50. As shown, the wheeled ride-on toy 50 is constructed to be horse-themed. Figure 7 ) supports a saddle 54 on which a user can sit. Wheels 62 are provided on each of the front legs 56 and the rear legs 58. Each wheel 62 rotates about an axle 64 supported by a wheel mount 66. Preferably, each wheel mount 66 is rotatable relative to the associated leg so that each wheel 62 can freely rotate about a generally vertical axis. In a preferred embodiment, the wheel mount 66 and the wheel 62 are casters. In the illustrated embodiment, the scooter 30 is arranged immediately behind the front legs 56 of the ride-on toy 50 so that the user's feet rest on the right foot pad 36 and the left foot pad 46, which is similar to the position where the user's feet would be arranged in the stirrup position on a real horse - that is, below and slightly forward of the saddle 54.

[0046] When the user controls the scooter 30 through foot input, the ride-on toy 50 follows the movement of the scooter 30. For example, Figure 3 As shown, the ride-on toy 50 moves forward and backward, turns right and left, and even rotates depending on the input provided to the scooter 30 by the user.

[0047] exist Figure 2 and Figure 3In the illustrated embodiment, the ride-on toy 50 is independent of the scooter 30, and there is no direct physical or electrical connection between them except through the rider. In other embodiments, the front legs 56 of the ride-on toy 50 can be connected to the scooter 30 to provide a physical connection that helps the scooter 30 guide and control the movement of the ride-on toy 50. Such a connection can take many forms. For example, in some embodiments, a strap can extend from the front legs to the scooter and extend around the scooter so that the left and right parts of the scooter can move without restriction. In other embodiments, one or more front legs can be attached to the housing and / or chassis of the scooter so that the ride-on toy is physically and rigidly attached to the scooter, thereby enhancing the direct connection between the movement of the scooter and the ride-on toy.

[0048] Next, refer to Figures 4 to 11 , another embodiment is shown in which an insert 70 is disposed between the left portion 32 and the right portion 42 of the scooter 30 and is configured to rotate about the wheel axle 72 of the scooter 30, but is constrained to not rotate about any other axis. Preferably, the insert 70 does not rotate with either scooter portion 32, 42 (within the operating range). A post 80 extends upward from the insert 70 to support the ride-on toy 50. With the post 80 rigidly attached to the insert 70 and the ride-on toy 50, the front legs 56 of the ride-on toy 50 are preferably located in front of the scooter 30 and raised above the ground, and the front legs do not have wheels. The rear legs 58 are still supported by wheels 34, 44 that can rotate about a vertical axis - or the axis of the rear legs 58 - to allow the ride-on toy 50 to continue to follow the movement of the scooter 30, including turning and rotating. Preferably, the rear wheel 62 does not play a role in steering or determining the direction of the ride-on toy 50.

[0049] Specific reference Figure 7 In a preferred embodiment, the ride-on toy 50 includes a frame structure 60 including a plurality of upper frame members 74 and lower frame members 76 interconnected by struts 78. A support plate 82 includes a mounting structure 87 configured to receive the posts 80. The frame 60 is configured to maintain the appearance of a theme (i.e., horse, dragon, unicorn, elephant, camel, cart, spaceship, etc.), support a user on the saddle 54 of the themed ride-on toy 50, and safely and effectively transfer the motion of the scooter 30 to the ride-on toy 50 and the rear legs 58 so that the ride-on toy 50 moves in unison with the scooter 30.

[0050] Special reference Figures 8 to 11, in one embodiment, components of a typical scooter may be modified to support mounting posts 80. As shown, a scooter chassis 84 includes a left chassis portion 86 and a right chassis portion 85 that are rotatably connected to each other via axle 72. In the illustrated embodiment, the axle is elongated relative to a conventional scooter and extends through an axle receiver 88 formed in the insert 70, which is disposed on the axle 72. Washers 89 are disposed on the axle 72, on either side of the insert 70. Post receivers 90 are disposed on the top of the insert 70 and are shaped and configured to receive the mounting posts 80.

[0051] In a typical scooter, a pin on the right portion 85 of the chassis fits into a slot in the left portion 86 to limit the rotation of the chassis parts relative to each other over an operational range. In the illustrated embodiment, a pin 92 extends from the right portion 85 of the chassis 84, and a slot 94 is formed in the insert 70. Preferably, the insert slot 94 is about half the length of a typical slot in the left portion 86 of the chassis, while the slot 96 in the left portion 86 remains at a normal length. In the illustrated embodiment, the insert 70 has two pins 98 that are configured to fit into the left portion slot 96. The pins 98 are configured to be able to move about half the length of a typical slot. Therefore, in this configuration, with the insert 70 in place, the total operational rotation between the left portion 86 and the right portion 85 will be approximately the same as that of a normal scooter without an insert. It should be understood that other specific structures may also be used to achieve this effect.

[0052] When the ride-on toy 50 is mounted to the scooter 30 via the posts 80, the ride-on toy 50 moves with the scooter 30. The mounting posts 80 transmit the motion of the scooter 30 to the frame 60, which is preferably rigid enough to transmit such motion through the rear legs 58 to the wheel mounts 66, which position the wheels 62 to roll as directed by the motion transmitted by the scooter 30 due to the wheel mounts' caster-like ability to freely rotate about the axis of the legs (and / or the vertical axis). In this way, a user sitting on the ride-on toy 50 can control the motion of the ride-on toy 50 by manipulating the foot pads 36, 46 with the user's feet on the scooter 30.

[0053] Continue to refer to Figures 8 to 11, the scooter 30 preferably includes various electronic components, including, for example, a controller 100 that includes a processor with memory. A battery 102 provides power. Wires 104 communicate from the controller 100 to such electronics, including through the axle 72, which is preferably hollow. For example, a left foot pad sensor 106 and a right foot pad sensor 108 sense user inputs and transmit them to the controller 100. Preferably, an axle hole 110 is formed through the axle 72 and is aligned with the post receptacle 90 of the insert 70. Wires extend from the controller 100 through the axle hole 110 into the post receptacle 90 and the post 80, terminating at an electronic connector 112 formed on the post 80. Of course, in other embodiments, such wires may terminate at a different type of connector, such as a free hanging connector.

[0054] See also Figure 7 , the mounting structure 87 of the ride-on toy 50 preferably also has an electronic connector 114 that is complementary to the post connector 112. Thus, when the post 80 is received in the mounting structure 87, the electronic connectors 112, 114 engage. Wires extend from the mounting structure electronic connector 114 to a ride-on toy controller 120, which preferably includes a microprocessor with memory. In this way, the toy controller 120 is electrically attached to the scooter controller 100. In a preferred embodiment, the toy controller 120 receives power and control data from the scooter controller 100. In this way, the toy controller 120 receives the motion data of the scooter 30 and therefore knows how the ride-on toy 50 moves (i.e., forward, backward, fast, slow, turn, twist, etc.).

[0055] Please refer to the specific Figure 7Preferably, the ride-on toy 50 includes multiple effects, such as visual, auditory, and haptic effects, which are connected to, powered by, and controlled by a toy controller 120, preferably using power from the battery 102 of the attached scooter. For example, a first lighting effect 124 may be a cluster of LED lights located at the horse's eyes 126, while a second lighting effect 128 may include a light strip located along the horse's mane 130 (or unicorn's horn, a car's dashboard, etc.), and a third lighting effect 132 may include a light strip extending along the horse's tail 134. A first speaker 136 may be located near the horse's mouth 138 to simulate neighing, snoring, etc., and a second speaker 140 is located within the body below the user. Haptic effects, such as a vibration motor 142, may be attached to the horse's saddle 54 and / or the frame 60 adjacent the saddle, and a second haptic effect 144 may include a motor configured to shake the horse's tail 134. Another haptic effect may include a smoke generator 146 placed near the horse's nostrils 148. Still another haptic effect may include a motor 150 placed at a hinge joint. Still another haptic effect may include a motor 150 placed at a hinge joint 152 in the horse's neck and configured to rotate the horse's head 154 up and down.

[0056] In some embodiments, the toy controller 120 will actuate one or more effects based on the data received from the scooter controller 100. For example, when the scooter data indicates that the toy 50 is moving forward, the controller will turn on the horse's eye lights 124, trigger the lights 128 on the "moving" mane 130, and actuate the body speakers 140 to make the horse's hooves make hoof sounds. And when the scooter data indicates that the scooter is moving at full speed, the toy controller 120 will increase the speed of the hoof sounds emitted by the body speakers 140, increase the speed of the moving lights 128, and periodically actuate the smoke generator 146 to blow smoke from the nostrils 148. If the user then changes the input to a sudden stop, the toy controller 120 will actuate the saddle vibrator motor 142 to vibrate the saddle 54, actuate the head speaker 136 to emit a loud neighing sound, flash the bristle light 128, actuate the body speaker 140 to emit horse hoof sounds corresponding to a rapidly decelerating horse, actuate the head motor 150 to rotate the head 154 backward, and actuate the smoke generator 146 to emit a rapid succession of smoke from the nostrils 148. In a preferred embodiment, the toy controller 120 is also configured to actuate auditory, visual, and other effects corresponding to the motion, including taking into account direction and acceleration, such as actuating the mouth speaker 136 to emit a neighing sound, and actuating the saddle motor 142 to vibrate the saddle 54. It should be understood that other effects and various configurations of effects may also be employed. Moreover, in embodiments having other themes (such as unicorns, elephants, Pegasus, cars, spaceships, etc.), different effects consistent with the theme and associated with various motion conditions may be employed.

[0057] Continue to refer to Figure 7 In a preferred embodiment, the toy controller 120 includes a wireless communication structure, such as an antenna and a transceiver, configured to wirelessly communicate with a remote computing device 160, such as a remote control, a smart phone, a tablet, or a laptop computer. The remote computing device can communicate with the toy controller 120 via such wireless communication. In some embodiments, the remote device 160 can access the memory of the controller 120 and modify the programming of the toy controller 120.

[0058] The toy controller can also preferably transmit instructions to the scooter controller 100 via a wired connection to change how the scooter 30 responds to user input. For example, in one embodiment, a user of a smartphone may have an app that enables the user to select between a beginner mode, an intermediate mode, and an advanced mode. When the smartphone sends a signal to operate in the beginner mode, the toy controller 120 can be configured to operate in a manner more suitable for very young children. For example, the vibration of the saddle 54 can be minimized, and the sounds can be more weird than real in order to attract very young children. These sounds can even include songs, and the theme toys can talk, laugh, etc. instead of simulating animal movements. In addition, in the beginner mode, the toy controller 120 will instruct the scooter controller 100 to change its response to user input. For example, the reaction speed of the scooter to the user's foot movement can be weakened and deliberately slowed, and the operating speed can be halved, reduced by two-thirds, etc., to enable safe use by very young children. In addition, certain movements (such as reversing or rotating) can be canceled and / or slowed to one-quarter speed.

[0059] In the intermediate mode, the sounds and reactions may be more realistic, but the speed and reaction time may still be limited. The advanced mode may anticipate full speed and the most advanced and realistic effects. In another embodiment, the app may have a quiet mode, including a mechanism for reducing the volume of or muting the auditory effects, and may include options to turn certain effects on or off. In some embodiments, the toy controller may communicate a status or alarm to a remote device. For example, when the smoke generator device needs to be refilled with smoke fluid, the toy controller may send a signal to the remote device. In further embodiments, the ride-on toy 50 may include additional sensors, such as proximity sensors, which communicate the proximity of external objects to the toy controller 120. In such an embodiment, when the toy controller 120 realizes that an object is very close to the toy 50, the toy controller will communicate instructions to the scooter controller 100 to limit certain operations. For example, the toy controller 120 may instruct the scooter controller 100 not to cause a rotation - regardless of the user input - to avoid hitting the sensed object. Such an embodiment may include an "internal" mode that activates the feature, and an "external" mode when the proximity sensor feature cannot be used.

[0060] In further embodiments, a user profile may be created with preferred settings for a particular user. For example, the first member of the series will always operate in beginner mode, while the second member of the series operates in advanced mode, but preferably with all rearward motions set to half speed and the vibration motor turned off. Selecting a profile for a particular user will cause the user to adopt the operating preferences of the selected profile. In some embodiments, the user profile may be saved in the memory of the toy controller 120. In other embodiments, the user profile may be saved in an online app and accessed via the remote device 160 when actuating control of the ride-on toy 50.

[0061] In further embodiments, the remote computing device 160 may operate as a remote controller. Thus, the toy controller 120 will receive input instructions from the remote device 160 and direct the scooter controller 100 how to control the scooter 30, regardless of any user foot input. Conversely, the remote control 160 will instruct the toy controller 120 how to move, and the toy controller 120 will transmit such movement instructions to the scooter controller 100, which will control the wheel motors 52 to apply such control instructions.

[0062] Refer to the following Fig.12, another embodiment of the insert 70 is shown. In this embodiment, the insert 70 is integrally formed and includes left and right hollow axle portions 164 (rather than separately formed axles). Control wires 166 pass through the hollow axle portions and the post receiving portion 90 to connect the toy controller 120 with the scooter controller 100. In the illustrated embodiment, a free-hanging connector 168 is provided to connect to the wires extending from the toy controller 120. In another embodiment, the toy controller 120 and the scooter controller 100 can be configured to share data back and forth wirelessly. In such an embodiment, preferably, the ride-on toy 50 also includes its own battery.

[0063] In a preferred embodiment, mounting post 80 is releasably attached in insert post receptacle 90 and / or ride-on toy mounting structure 87. The electronic connector may be configured to engage in a toy mounting structure, such as Figure 7 As shown, or if desired, engaged within the insert post receiving portion. In some embodiments, the user is able to obtain a second themed ride-on toy structure (sans scooter) by being able to detach the original ride-on toy 50 from the scooter 30 and engage the second ride-on toy to the scooter, including electrically connecting the second ride-on toy. Thus, the scooter can interchangeably provide motion and power to multiple different ride-on toys, each with its own customized set of themed effects.

[0064] In other embodiments, structures such as shock absorbers can be incorporated into the mounting posts and / or rear legs to provide a smooth ride. Additionally, the mounting posts and / or legs can have telescoping structures driven by motors to impart up / down motion to the ride-on toy. This up / down motion can be configured to vary in frequency with speed and can be configured to vary in amplitude based on personalized settings and patterns and / or in conjunction with detected motion.

[0065] exist Figures 8 to 11 In the illustrated embodiment, the mounting post has a circular cross-section. It should be understood that in other embodiments, the mounting post can have other cross-sectional shapes, such as square, hexagonal, etc. Such shapes can facilitate the transfer of rotational motion from the scooter to the ride-on toy. In other embodiments, other structures such as keying structures can engage the mounting structure and / or the post receiving portion to prevent the mounting post from rotating relative to such mounting structure. In other embodiments, the insert can be configured to be rigidly attached to the front legs of the ride-on toy frame, rather than using a mounting post extending between the scooter and the ride-on toy body.

[0066] Refer to the following Figure 13 to Figure 16, shows another embodiment in which the mounting post 80 is rigidly and permanently attached to the frame 60, and in particular to the support plate 82. In the illustrated embodiment, the mounting post 80 has a non-circular cross-section. More specifically, the cross-section of the mounting post is generally oval or elliptical and increases in both the major and minor axes from its bottom end (where the mounting post engages the insert 70) to its top end (where the mounting post is attached to the support plate 82). The post interface 170 is defined at the bottom end and is configured to be received in the complementary formed post receiving portion 90 of the insert 70. In this way, when the mounting post 80 is installed in the post receiving portion 90 of the insert 70, due to the elliptical shape of the mounting post, the mounting post 80 effectively and efficiently transmits the rotation of the scooter 30 to the ride-on toy 50 with very little play.

[0067] In the illustrated embodiment, the head 154 of the ride-on toy 50 includes a head post 174 that is configured to be received by a head receptacle 176 supported by the frame 60. The head post 174 can be fixed in place in the head receptacle 176 via fasteners 178. In addition, in the illustrated embodiment, the non-load-bearing front legs 56 are each supported by a rotatable connector 180 that includes a spring-loaded catch 182. In practice, the legs 56 can each be rotated about a vertical axis from a storage position (as opposed to the illustrated position) to the illustrated extended position. When the front legs 56 are in the desired extended position, the spring-loaded catch 182 will actuate, thereby retaining the front legs 56 in the extended position. Preferably, the spring-loaded catch 182 will also be therein to releasably retain the front legs 56 in the storage position. In this way, the ride-on toy 50 of the present invention can be partially disassembled and compressed for storage and transportation.

[0068] Fig.13 and Fig.14 The frame 60 of the ride-on toy 50 is shown without the overlay of the themed features. It should be understood that this basic frame 60 can accommodate a variety of variations of thematic overlays, including horse themes, and can also accommodate various visual, auditory, and tactile effects appropriate to the selected theme. For example, instead of securing the head to the head receptacle 176, a toy laser gun is secured to the head post 174, and the frame 60 is covered with themed equipment consistent with a spaceship. Visual, auditory, and tactile effects particularly closely related to space flight / space combat competitions can be included, including rocket engine noises, laser shooting sounds and light effects, and even tactile vibrations caused by the spaceship being hit by other lasers and / or simulated meteor strikes and radio transmissions from teammates.

[0069] Please refer to the following for details Fig.15 and Fig.16A , 16B, the illustrated embodiment includes a bearing support interface between the insert 70, the wheel axle 72 and the right and left chassis portions 85, 86. Specifically, each of the right and left chassis portions 85, 86 includes a mounting block 190 having an insert sidewall 192 and a wheel sidewall 194, and an axle passage 196 extending through the mounting block. The wheel axle 72 extends through the axle passage 196 and the axle receiving portion 88 of the insert 70. A plurality of bearing assemblies 200 are provided, each bearing assembly including a bearing cup 202, a bearing sleeve 204 and a bearing race 206, one bearing assembly being provided at each of the insert sidewall 192 and the wheel sidewall 194 to rotatably support the wheel axle 72 relative to the mounting block 190. The bearing assemblies 200 on the insert sidewall 192 are also received in a bearing seat 208 formed in the insert 70 and are configured to provide a limited clearance space between adjacent insert sidewalls 192 of the insert 70 and the mounting block 190. Spacers 209 may be provided on the axle and between the bearing assemblies 200 .

[0070] The bearing support interface is preferably constructed with very little or no play. To this end, one end of the axle 72 includes a retaining ring 210, a washer 212, and a race stop 214, and at the opposite end of the axle 72, a threaded bearing race 216 replaces the race 206, and a locking nut 218 secures the entire interface together. Because the bearing supported interface has very little or no play, rotation about an axis transverse to the axle 72 (such as rotation of the scooter 30) is more easily and predictably transmitted to the mounting post 80 and the ride-on toy 50.

[0071] In another embodiment, rather than using a retaining ring, washer and race stop, a raised flange may be provided on the first end of the axle for retaining the bearing assembly.

[0072] The embodiments discussed herein generally provide a ride-on toy 50 that is attached to a scooter 30 via an insert 70. In other embodiments, different structures may be used to attach the ride-on toy 50 to the scooter 30. For example, referring to Fig.17 and Fig.18 , an embodiment of the ride-on toy 50 may include a clamp 220 defining a collar 222 that is configured to be openable and closable by a wrench 224. In use, the collar 222 may be opened and pulled around the center portion of a typical scooter 30, and the wrench 224 may then be actuated to close the collar 222 and tighten the collar 222 to a certain degree around the center of the scooter 30. The scooter 30 is then attached to the ride-on toy 50, and the ride-on toy 50 will move with the scooter 30 in a manner similar to the above-described embodiments.

[0073] The above embodiment adopts the scooter in which the left and right parts rotate relative to each other. It should be understood that the principles discussed here can be applied to other configurations of the two-wheeled self-balancing scooter, such as the configuration in which the left and right parts do not rotate relative to each other.

[0074] Refer to the following Fig.19A , 19B , an embodiment of a self-balancing scooter 30 is shown in which the body 226 of the scooter is integral. Thus, although sensors in the right foot pad 36 and the left foot pad 46 detect user input to communicate with the scooter controller, the body 226 is not divided into right and left portions that rotate relative to each other. In the illustrated embodiment, the attachment member 230 includes a top 232 and a bottom 234 configured to surround a portion of the body 226 of the scooter 30. The top 232 and the bottom 234 are preferably secured to each other, sandwiching the body 226 between the top 232 and the bottom 234. The top 232 includes an interface 236 that includes a male interface member 238 that is configured to be received by a female receiving portion (not shown) in an embodiment of the mounting post 80 of the ride-on toy 50. Thus, the ride-on toy 50 can be selectively attached to and work with a variety of types of scooters 30.

[0075] Fig. 20 Another embodiment is shown in which the connecting member 230 is configured to bolt directly to the scooter body 226 and includes a post receiving portion 90 configured to receive the mounting post 80 of the ride-on toy 50. As an alternative to bolting, the illustrated attachment member 230 includes a protrusion 240 configured to fit under the right foot pad 36 and the left foot pad 46 so that the foot pads hold the attachment member 230 in place on the scooter body 226.

[0076] Next, refer to Fig.21 Another embodiment of the attachment member 230 having a protrusion 240 includes an interface 236 having a sliding receiving portion 242. The mounting post 80 of the ride-on toy 50 includes a flange 244 around the bottom end of the mounting post, which is configured to be received in the sliding receiving portion 242 to securely fix the ride-on toy 50 to the scooter 30.

[0077] It should be understood that other embodiments may employ other structures to secure the ride-on toy to the scooter, whether through the insert 70 or through the attachment member 230. Also, for example, the interface 236 for connecting the mounting post 80 may take a variety of specific structural shapes, whether used with the attachment member 230 shown, or in embodiments using the insert 70.

[0078] Refer to the following Fig. 22 and Fig.23, another embodiment of the ride-on toy 50 includes a frame 60 attached to the scooter 30 via a mounting post 80. The illustrated frame 60 is supported by a single wheel mount 66 and a wheel 62, and the wheel mount 66 is configured to freely rotate about a vertical axis. The illustrated wheel 62 is relatively large, such as having a diameter that is as large as or larger than the diameter of the wheels 34, 44 of the scooter 30. In a preferred embodiment, the wheel 62 includes an inflatable tire that is configured to support the weight of a larger child, teenage boy, etc. A saddle 54 is supported by the frame 60, and in the illustrated embodiment, the saddle 54 is similar to a typical bicycle seat.

[0079] The handlebars 250 are supported by a neck 252 that is attached to the mounting post 80 and the frame 60. The handlebars 250 do not serve a steering function and preferably only provide a gripping location for the rider who is seated on the saddle 54 while riding. In a preferred embodiment, the neck 252 provides a rigid connection to both the mounting post 80 and the frame 60, so that the frame 60, the neck 252, and the mounting post 80 generally function effectively as a unitary frame member. In this manner, and as discussed in the above embodiments, the ride-on toy 50 moves with the scooter 30, although it is different in shape from the above ride-on toy embodiments.

[0080] Continue to refer to Fig. 22 and Fig.23 , the illustrated embodiment does not include the theme element. Such an embodiment is preferred for older children, teenagers, and adults who enjoy the motion of the ride-on toy 50 and do not need the theme element. Moreover, it should be understood that accessories can be added. For example, Fig.23 As shown, a mounting member 254 can be provided on the handle 250. The mounting member 254 can have many configurations. In the illustrated embodiment, the mounting member 254 is configured to hold a toy gun, such as a water gun or Dart guns. Groups of riders can use their ride-on toys in play combat, such as airplane dogfights.

[0081] In other embodiments, the handle 250 can be configured to rotate about the axis of the neck 252 to accommodate the comfort of the user or to provide a range of motion, such as for aiming a game gun 256 secured in the mount 254. In preferred embodiments, the range of rotation of the handle 250 is limited, such as to a total rotation of 90° or 60° (i.e., 45° or 30° in each rotational direction).

[0082] In other embodiments, the frame 60 may also rotate about the axis of the neck 252. However, excessive rotation of the frame 60 about the neck 252 may destabilize the ride-on toy 50. Therefore, in other embodiments, such rotation is limited to a range such as a total rotation of 90° or 60° (i.e., 45° or 30° in each rotation direction).

[0083] exist Fig. 22 and Fig.23 In the illustrated embodiment, the ride-on toy 50 is attached to the scooter 30 via the clamp 22. It should be understood that in other embodiments, several other types of attachment mechanisms may be employed as discussed in other embodiments. Fig.24 , shows another embodiment in which the frame 60 is permanently attached to the scooter 30. In this embodiment, the mounting posts 80 and the insert 70 are a unitary member.

[0084] An old and simple themed toy is the "pony stick," which basically consists of a broomstick with a themed feature (such as a horse's head) on one end. A child can pretend to ride a horse, holding the stick between his legs while leaping forward, preferably while wearing a cowboy hat.

[0085] Reference Fig.25 , an embodiment of a subject toy structure 260 is shown that can be removably attached to a self-balancing scooter 30. The illustrated subject structure 260 includes a pony stick 262 having a horse's head 154. In the illustrated embodiment, the clamp 220 is configured to fit around the scooter 30 at the joint between the right portion 32 and the left portion 42 and clamped thereon.

[0086] The post 264 extends upwardly from the clamp 220. In the illustrated embodiment, the post 264 includes a main post member 266 and a secondary post member 268. The secondary post member 268 is slidably partially received within the main post member 266 in a telescoping configuration to adjust the length of the post 264. The telescoping clamp 270 secures the position of the secondary post 268 relative to the main post 266 to maintain the post 264 at a selected length. Preferably, the post 264 is connected to the clamp 220 by a ball joint 272 to allow the post 264 to have a wide range of movement and adjustment about the clamp 220 (and the associated powered scooter 30).

[0087] Continue to refer to Fig.25, in the illustrated embodiment, the pony stick 262 is attached to the top of the upright 264 via a top clamp 274. In the illustrated embodiment, the pony stick 262 can be slid longitudinally within the top clamp 274 to a desired position and selectively retained in that position by the top clamp 274. The top clamp 274 is preferably attached to the top end of the upright 264 at an articulated connector 276 that is configured such that the top clamp / pony stick can rotate in a vertical plane (i.e., in a plane parallel to and / or including the upright) about the articulated connector 276. The connection can also be configured such that the top clamp / pony stick can rotate in a horizontal plane, i.e., in a plane perpendicular to the upright.

[0088] Fig.25 The structure shown enables the theme toy structure 260 to be attached to any scooter, such as by the shown clamps of any connection structure discussed in other embodiments. Preferably, adjustments can be made to customize the structure 260 to the size of the rider. During use, the user usually rides on the scooter 30 in a standing orientation. However, the pony stick 262 is supported in an ideal position so that the user can play like riding a horse, and the user can even rotate the pony's head up and down to simulate a prancing horse. In addition, the pony stick 262 will adjust the forward and side tilt of the user's body to control the self-balancing scooter 30. In addition, although the scooter 30 supports the weight of the theme toy structure 260, it is still the user who keeps the theme toy structure in place when riding.

[0089] In at least some embodiments, the theme toy structure 260 can be physically and electrically attached to the scooter 30, and the theme toy structure 260 can include electric elements that can be powered by the scooter's battery. Of course, in other embodiments, the structure 260 can have its own battery to power these elements and can only be physically attached to the scooter 30. In one embodiment, the theme structure 260 can include a button that can be actuated by the user to trigger a sound effect. As discussed in other embodiments, other effects can be triggered by conditions such as speed, direction, etc. Such effects can include auditory, visual and / or tactile effects.

[0090] It should be understood that the principles discussed herein can be used with other specific structures and other subject structures. For example, in another embodiment, the subject structure can simulate the shape of an airplane, spaceship, car, etc., rather than the shape of a pony stick. The specific structure of the uprights can be slightly different, but the principle remains that the subject structure can be attached to and supported by a powered self-balancing scooter, while being held and used by the rider when standing and riding the scooter 30.

[0091] It should also be understood that additional embodiments may include additional features. For example, some embodiments may include a toy gun structure - such as Dart guns, water guns, laser tag and / or other types of game guns. Additional embodiments may include mounts so that participants can add their own game gun structures to the theme structure. A group of riders can then, for example, participate in an "air combat" simulation or game.

[0092] Refer to the following Fig.26 and Fig. 27 , another embodiment of an electric themed ride-on toy 280 is provided. In the illustrated embodiment, the ride-on toy 280 is configured to be related to a horse theme and includes a head 154, a mane 130, a tail 134, etc. The illustrated ride-on toy 280 may share similar components with some embodiments of the ride-on toy 50 discussed herein. For example, the theme elements of the ride-on toy 280 are supported by a frame 60 having an upper member 74 and a lower member 76 and a pair of rear legs 58, which are attached to a wheel mount 66, which is configured to freely rotate about the axis of the rear legs 58, which axis is preferably generally vertical. The wheel mount 66 supports a horizontal axle 64, and the wheel 62 rotates about the horizontal axle 64. The wheel mount / wheel may be a caster.

[0093] In the illustrated embodiment, a pair of front legs 56 are connected to motors 52 mounted in the hubs of the right and left wheels 34, 44. As such, the motors 52 are substantially invisible. Each motor is configured to drive a respective wheel 34, 44 forward or rearward. Preferably, each motor 52 is rigidly attached to a respective leg 56 so that the motor rotates differently than the rear wheels 62. More specifically, the motor / wheel combination does not rotate about a vertical axis in a manner that would be considered steering of the wheel.

[0094] Continue to refer to Fig.26 and Fig. 27 The frame 60 preferably supports a controller 100 and a battery 102 that are connected to the motor 52 to control the motor. Based on the user's input, the controller 100 directs the right wheel 34 and the left wheel 44 to move forward and backward to control the movement of the ride-on toy 280 in a manner similar to the control strategy used by the self-balancing scooter 30 described above. In fact, from a movement perspective, this embodiment of the ride-on toy 280 moves in a manner similar to how the embodiment of the ride-on toy 50 described above would move if the scooter 30 was attached at the front legs 56.

[0095] Stirrup supports 282 hang down from frame 60 on each side of ride-on toy 280, roughly aligned with saddle 54. Stirrups 284 hang from stirrup supports 282, and each stirrup 284 preferably includes stirrup plates 286, which are configured to receive the user's feet and rest on them. Sensors 288 associated with stirrup plates 286 measure the user's foot inputs and transmit these inputs to controller 100. In this way, the user's foot input can be used to control ride-on toy 280, including forward, backward, steering and rotational motion. This control is dominated by wheels 34, 44 at front legs 56, and rear wheels 62 only support ride-on toy 280 without providing steering control. It should be understood that various sensor configurations can be used to obtain the user's foot input. For example, in one embodiment, stirrup plate sensor 288 measures the rotation angle of stirrup plate 286 relative to the associated stirrup 284 as user input. In further embodiments, in addition to or in lieu of such a rotation sensor, a pressure sensor 290 can measure the difference in user foot pressure between the front and rear portions of the stirrup plate 286, and the controller 100 can determine a control strategy based on such a measurement.

[0096] It should be understood that the illustrated subject power ride-on toy 280 may employ a number of visual, auditory, and tactile effects, including the example effects discussed in other embodiments, and that the controller 100 may include wireless communication structures that enable monitoring, programming, and even control via a remote computing device 160.

[0097] In further embodiments, the controller 100 may take into account further inputs when controlling the motor 52. For example, in the illustrated embodiment, the head 154 is hingedly attached to the head post 174 at the articulated joint 152, and the rope 292 is accessible to the rider and is connected to the nose of the head 154. A user pulling the rope 292 upwards may thus rotate the head 154 upwards - clockwise around the articulated joint 152 in the illustrated view, and a user pulling the rope 292 downwards may rotate the head 154 downwards - counterclockwise around the articulated joint 152 in the illustrated view. The joint sensor 294 is capable of measuring such rotations and sending data about such rotations to the controller 100. For example, a user pulling the rope to rotate the head 154 downwards sends a signal for forward movement, while pulling backwards on the rope 292 to rotate the head 154 upwards sends a signal for slowing / stopping, and even backward movement. In this configuration, the rope 292 only provides forward / backward guidance, without steering. Instead, steering input is taken from stirrup 286 .

[0098] In some embodiments, forward / backward input may be taken from both the rope 292 and the stirrup 286, with the rope 292 input overriding the stirrup 286 input, but only with respect to the forward / backward input. In other embodiments, the stirrup input is the default input for all controls, except that if a sharp pull back on the rope 292 is detected, an emergency stop control is triggered and the ride-on toy 280 will immediately stop all motion. Of course, it should be understood that additional control routines and sensor inputs may be employed. For example, in some embodiments, the sensor may be configured to detect directional (i.e., right and left) pulls on the rope 292 so that steering control can also be based on the rope input.

[0099] The above embodiments disclose structures with substantial specificity. This provides a good background for disclosing and discussing the subject matter of the present invention. However, it should be understood that other embodiments may adopt different specific structural shapes and interactions.
