DETAILED DESCRIPTION

The present invention relates to a toy vehicle that includes a toy vehicle body and a pair of wheel supports located on opposite sides of the toy vehicle body. In one embodiment, each of the wheel supports includes a pair of wheels rotatably mounted to the wheel support. The toy vehicle has a drive system that includes a pair of motors, each of which is operable to move one of the wheel supports and the wheels coupled to the wheel support. Each wheel support is movable between a retracted position in which the wheel support extends along a side of the toy vehicle body, and an extended position in which the wheel support extends downwardly from the toy vehicle body with a front end of the wheel support being spaced apart from the toy vehicle body.

FIG. 1 is a schematic diagram of an embodiment of a toy vehicle system according to the present invention. In this embodiment, the toy vehicle system 5 includes a remote control 10 and a toy vehicle 20. The remote control 10 includes several inputs 12 and a power source 14, such as batteries. The inputs 12 can include one or more directional inputs, such as directional sticks or directional pads that can be used to move the toy vehicle 20 forward or backward and/or steer the toy vehicle 20.

An exemplary embodiment of the toy vehicle 20 is shown in FIG. 1. The toy vehicle 20 includes an electronic system 22 that includes a power source 24 and a controller 26. In one embodiment, the power source 24 is a rechargeable battery. It is to be understood that each of remote control 10 and the electronic system 22 includes wireless communication components (not shown) that facilitate communications between the remote control 10 and the electronic system 22.

The toy vehicle 20 includes a drive system or drive assembly 25, which is shown in the schematic diagram of FIG. 1. In one embodiment, the drive system 25 includes two motors 30 and 60, each of which can be independently operated. A user can actuate motor 30 and motor 60 simultaneously to drive the toy vehicle 20 forward or backward on a support surface. Also, a user can actuate either motor 30 or motor 60 to turn the toy vehicle 20 toward the left or toward the right, as desired. Motor 30 has an output 32 coupled thereto, which in this embodiment, is a gear mounted on the output shaft of the motor 30. Similarly, motor 60 has an output 62 coupled thereto, which is a gear coupled to the output shaft of the motor 60.

The drive system 25 includes one or more gears 34 that are positioned downstream of motor 30. In one embodiment, a single gear 34 is in engagement with the teeth of output 32 of motor 30. In another embodiment, one gear 34 is in engagement with the teeth of output 32 of motor 30, and at least one additional gear is engaged with the teeth of gear 34. Similarly, the drive system 25 includes one or more gears 64 that are positioned downstream of motor 60. In different embodiments, either a single gear 64 or multiple gears 64 are provided.

Referring back to gear 34, toy vehicle 20 includes a rear axle 40 to which a rear wheel 42 is coupled. In this embodiment, the rear wheel 42 is fixedly coupled to the rear axle 40 such that when the rear axle 40 rotates, the rear wheel 42 rotates as well. The rear axle 40 includes teeth that can engage the teeth of gear 34. In one embodiment, the teeth of rear axle 40 can be formed integrally with the axle. In another embodiment, a separate gear or ring can be coupled to the rear axle 40, and that separate gear or ring can include teeth formed thereon. Thus, when gear 34 is driven, gear 34 drives rear axle 40 and causes rear wheel 42 to rotate as well.

Similarly, toy vehicle 20 includes another rear axle 70 to which another rear wheel 72 is coupled. Rear wheel 72 is fixedly coupled to the rear axle 70 such that when the rear axle 70 rotates, the rear wheel 72 rotates as well. The rear axle 70 includes teeth that can engage the teeth of gear 64. In one embodiment, the teeth of rear axle 70 can be formed integrally with the axle. In another embodiment, a separate gear or ring can be coupled to the rear axle 70, and that separate gear or ring can include teeth formed thereon. Thus, when gear 64 is driven, gear 64 drives rear axle 70 and rear wheel 72 to rotate as well. Notably, each of the gears 34 and 64 is driven independently from each other because of their coupling to motors 30 and 60, respectively. It is to be understood that motors 30 and 60 can be operated simultaneously or at different times from each other. In addition, motors 30 and 60 can be operated in the same direction or in opposite directions from each other. As a result, gears 34 and 64, rear axles 40 and 70, and rear wheels 42 and 72 can be rotated respectively relative to each other in a variety of manners.

Referring to FIG. 1, the drive system 25 includes a set of gears 36, one of which is engaged with the teeth associated with rear axle 40. As rear axle 40 rotates, the gear 36 in engagement with rear axle 40 also rotates. The set of gears 36 includes several gears that are arranged laterally in series, with each gear in the set of gears 36 being engaged with at least one other gear in the set. The drive system 25 also includes a front axle 44 to which a front wheel 46 is coupled. The front axle 44 is spaced apart from the rear axle 40. The set of gears 36 are located between the rear axle 40 and the front axle 44. As the rear axle 40 rotates, the rear axle 40 is engaged the first gear in the set of gears 36, thereby causing that gear to rotate. Each gear in the set of gears 36 rotates and the last gear in the set is engaged with the front axle 44, thereby causing it to rotate. As front axle 44 rotates, it causes the front wheel 46 to rotate. When motor 30 operates, it causes rear axle 40 and front axle 44 to rotate, and as a result, rear wheel 42 and front wheel 46 to rotate.

The drive system 25 also includes another front axle 74, which is similar to front axle 44. The drive system includes another set of gears 66, one of which is engaged with the teeth associated with rear axle 70. As rear axle 70 rotates, the engaged gear in the set of gears 66 also rotates. The set of gears 66 includes several gears that are arranged laterally in series, with each gear in the set of gears 66 being engaged with at least one other gear in the set. The front axle 74 includes a front wheel 76 coupled thereto. The front axle 74 is spaced apart from the rear axle 70. The set of gears 66 are located between the rear axle 70 and the front axle 74. As the rear axle 70 rotates, the rear axle 70 is engaged with and causes the first gear in the set, which is engaged with the rear axle 70, to rotate. Each gear in the set of gears 66 rotates and the last gear in the set is engaged with the front axle 74, thereby causing it to rotate. As front axle 74 rotates, it causes the front wheel 76 to rotate. When motor 60 operates, it causes rear axle 70 and front axle 74 to rotate, and as a result, rear wheel 72 and front wheel 76 to rotate.

Turning to FIG. 2, a schematic view of additional components of the toy vehicle 20 is illustrated. Toy vehicle 20 includes a pair of wheel support arms 50 and 80 that are pivotally mounted to the body of the toy vehicle 20. As discussed above with respect to FIG. 1, toy vehicle 20 has an electronic system 22 that is connected to motors 30 and 60, which in turn are connected to output 32 and gear 34 and to output 62 and gear 64, respectively. In one embodiment, gear 34 has a first set of teeth formed thereon that engage with rear axle 40, as described above. Gear 34 also has a second set of teeth formed thereon that engage with teeth associated with wheel support arm 50. As gear 34 rotates, not only does rear axle 40 rotate, but wheel support arm 50 also rotates. The extent to which wheel support arm 50 rotates can be limited. The wheel support arm 50 includes a projection 52 extending therefrom that is used with a limiter.

Similarly, gear 64 has a first set of teeth formed thereon that engage with rear axle 70. Gear 64 also has a second set of teeth formed thereon that engage with teeth associated with wheel support arm 80. As gear 64 rotates, not only does rear axle 70 rotate, but wheel support arm 80 also rotates. The extent to which wheel support arm 80 rotates can be limited. The wheel support arm 80 includes a projection 82 extending therefrom that is used with a limiter.

In an alternative embodiment, shown in FIG. 2 in dashed lines, gears 34 and 64 are engaged with rear axles 40 and 70, respectively, causing them to rotate when gears 34 and 64 rotate. Each of the rear axles 40 and 70 is engaged with one of the wheel support arms 50 and 80, respectively, and as a result, rotation of the rear axle causes rotation of the corresponding wheel support arm. The direct engagement may be achieved by way of the engagement of teeth on each component, an intermediate gear between a rear axle and a wheel support arm, and/or a clutch located between the rear axle and the wheel support arm. In one embodiment, a clutch allows the rear axle to continuously rotate while allowing motion of the wheel support arm to be limited.

Referring to FIG. 2, the toy vehicle 20 includes a vehicle body 90 that has a pair of slots 92 and 94 formed therein. Each of the slots 92 and 94 is arcuate and is sized to receive one of the projections 52 and 82. In particular, projection 52 travels in slot 92 and projection 82 travels in slot 94. The drive system 25 is configured so that while the range of rotation of each of wheel support arms 50 and 80 is limited by the range of travel of projections 52 and 82 in slots 92 and 94, the corresponding rear axles 40 and 70 can continue to be driven.

Turning to FIG. 3, a schematic diagram representing the movement of the wheel support arms 50 and 80 is illustrated. Wheel support arm 50 is pivotally coupled to vehicle body 90 and includes front wheel 46 coupled thereto. In one embodiment, the wheel support arm 50 has a first end and a second end opposite to the first end. The wheel support arm 50 is coupled to the vehicle body 90 proximate to the first end, and the front wheel 46 is coupled to the wheel support arm 50 proximate to the second end.

The wheel support arm 50 can be placed in a lowered or extended position 54 by motor 30. In this extended position 54, the wheel support arm 50 is proximate to a support surface or object, thereby resulting in the front wheel 46 engaging the support surface or object. The motor 30 can be actuated to move the wheel support arm 50 to its base or retracted position 56, which is illustrated in dashed lines in FIG. 3. When wheel support arm 50 is in its retracted position 56, front wheel 46 is proximate to the toy vehicle body 90. The range of motion of wheel support arm 50 between its extended position 54 and its retracted position 56 is limited by the length of the slot 92 formed in the vehicle body 90 of toy vehicle 20.

Turning to wheel support arm 80, wheel support arm 80 is pivotally coupled to vehicle body 90 and includes front wheel 76 coupled thereto. Similar to wheel support arm 50, wheel support arm 80 has its own first end and its own second end opposite to the first end. The wheel support arm 80 is coupled to the vehicle body 90 proximate to its first end, and the front wheel 76 is coupled to the wheel support arm 80 proximate to its second end.

The wheel support arm 80 can be placed in a lowered or extended position 84 by motor 60. In this extended position 84, the wheel support arm 80 is proximate to a support surface or object, thereby resulting in the front wheel 76 engaging the support surface or object. The motor 60 can be actuated to move the wheel support arm 80 to its retracted position 86. When wheel support arm 80 is in its retracted position 86, front wheel 76 is proximate to the toy vehicle body 90. The range of motion of wheel support arm 80 between its extended position 84 and its retracted position 86 is limited by the length of the slot 94 formed in the vehicle body 90 of toy vehicle 20.

In view of the motors 30 and 60 being independently operable, wheel support arms 50 and 80 can be moved independently between their extended positions 54 and 84 and their retracted positions 56 and 86, respectively.

Turning to FIG. 4, a perspective view of an embodiment of a toy vehicle assembly or system according to the present invention is illustrated. In this embodiment, the toy vehicle system includes a toy vehicle 100 and a remote control 500. The remote control 500 can be paired with an electronic system of the toy vehicle 100 so that user inputs to the remote control 500 are sent to the toy vehicle 100 to cause certain movements to occur. In this embodiment, the remote control 500 includes a housing or body 502 and several inputs, such as a directional stick 504 used to drive the toy vehicle forward or backward, a directional stick 506 used for steering, an action button 508 used to cause the toy vehicle 100 to perform a stomping-like action (as explained in more detail below), and a pair of buttons 510 and 512 used for steering.

Toy vehicle 100 includes a body 110 with a front end 120 and an opposite rear end 122. The body 110 also includes opposite side portions 124 and 126. The various features and components of the toy vehicle 100 are described in detail relative to the following figures.

Referring to FIG. 5, a perspective view of toy vehicle 100 is illustrated. Toy vehicle 100 has a body 110 that includes an upper portion 112 and a lower portion 114, with the upper portion 112 coupled to the lower portion 114 via connectors (not shown). Toy vehicle 100 also has a longitudinal axis 128 that extends from the front end 120 to the rear end 122. In FIG. 5, the toy vehicle 100 is illustrated in its lowered configuration 116. Toy vehicle 100 includes a wheel support or wheel support arm 300 to which two wheels are coupled. In this lowered configuration 116, the wheel support arm 300 is positioned proximate to the toy vehicle body 110.

Turning to FIGS. 6 and 7, a front view and a rear view of toy vehicle 100, respectively, are illustrated. The upper portion 112 and the lower portion 114 of the toy vehicle body 110 are visible in each of those figures. Toy vehicle 100 has a wheel support or wheel support arm 200 on one side of the toy vehicle body 110, and another wheel support or wheel support arm 300 on the other side of the toy vehicle body 110. In FIG. 6, the front ends 202 and 302 of the wheel supports 200 and 300, respectively, are located near the front end 120 of the toy vehicle 100. In FIG. 7, the rear ends 204 and 304 of the wheels supports 200 and 300, respectively, are located near the rear end 122 of the toy vehicle 100.

In both FIGS. 6 and 7, wheel support 200 is illustrated in a base or retracted position 206, and wheel support 300 is illustrated in its own base or retracted position 306. Each of the wheel supports 200 and 300 is pivotally mounted or coupled to the toy vehicle body 110. Each of the wheel supports 200 and 300 is movable and can be moved to different positions relative to the toy vehicle body 110, one of which is its retracted position 206 or 306.

When wheel support 200 is in its base or retracted position 206, wheel support 200 is proximate to and extends along the toy vehicle body 110. In particular, the wheel support 200 extends alongside portion 124 of the body 110. As described in greater detail below, wheel support 200 includes a pair of wheels coupled thereto. When wheel support 200 is in its retracted position 206, the wheels coupled to the wheel support 200 are adjacent to the toy vehicle body 110. Similarly, when wheel support 300 is in its base or retracted position 306, wheel support 300 is proximate to and extends along the toy vehicle body 110. In particular, the wheel support 300 extends alongside portion 126 of the body 110. Wheel support 300 also includes a pair of wheels coupled thereto. When wheel support 300 is in its retracted position 306, the wheels coupled to the wheel support 300 are adjacent to the toy vehicle body 110. Each of the wheel supports 200 and 300 extends parallel to each other when the wheel supports 200 and 300 are in their respective retracted positions 206 and 306.

Turning to FIGS. 8 and 9, the toy vehicle 100 is illustrated in another configuration. In this configuration 118, the toy vehicle body 110 and the wheel supports 200 and 300 are spaced apart from each other at the front ends of the wheel supports 200 and 300. As a result, the toy vehicle body 110 appears to be raised and angled upward relative to a support surface on which the wheels are located. In this configuration 118, each of the wheel supports 200 and 300 has been moved to its lowered or extended position 208 and 308, respectively, by the drive system in the toy vehicle 100. In this embodiment, each of the wheel supports 200 and 300 is pivotable about an axis that is near or proximate to the rear end of the wheel support. As shown in FIG. 9, when wheel supports 200 and 300 are in their extended positions 208 and 308, the rear ends of the wheel supports 200 and 300 are still coupled to the toy vehicle body 110, and the front ends of the wheel supports 200 and 300 are moved away from the toy vehicle body 110, and in particular, the lower portion 114 of the toy vehicle body 110. In their extended positions 208 and 308, the wheel supports 200 and 300 extend downwardly from the toy vehicle body 110, and each of the wheel supports 200 and 300 extends in a direction parallel to each other.

Wheel support 200 is movable by the drive system of the toy vehicle 100 between its base or retracted position 206 and its extended position 208 relative to the toy vehicle body 110. Similarly, wheel support 300 is movable by the drive system of the toy vehicle 100 between its base or retracted position 306 and its extended position 308 relative to the toy vehicle body 110. The drive system includes two motors that operate independently of each other. The motors can be operated simultaneously, or at different times than each other. One motor is connected to wheel support 200 via one or more gears. Similarly, the other motor is connected to wheel support 300 via one or more other gears.

Referring to FIGS. 10 and 11, the toy vehicle 110 is illustrated in yet another configuration. In this configuration, one of the wheel supports 200 and 300 is in its base or retracted position, and the other of the wheel supports 200 and 300 is in its extended position. In this particular example, wheel support 200 is in its extended position 208 in which it extends away from the toy vehicle body 110, and wheel support 300 is in its retracted position 306 in which it extends along the side of the toy vehicle body 110. When one of the wheel supports is in its retracted position and the other of the wheel supports is in its extended position, the wheel supports extend in directions not parallel to each other.

Each of the wheel supports 200 and 300 includes a pair of wheels rotatably coupled thereto. The wheels are discussed in more detail relative to FIG. 12. Referring to FIGS. 6-11, which show the wheel supports 200 and 300 in different positions relative to the toy vehicle body 110, the corresponding positions of the wheels coupled to the wheel supports 200 and 300 are shown. When a wheel support is in its base or retracted position, both of the wheels coupled to the wheel support are proximate to the toy vehicle body 110. When a wheel support is in its extended position, its rear wheel remains proximate to the toy vehicle body 110 due to its proximity to the pivot point of the wheel support, and its front wheel is in a lowered position or spaced apart from the toy vehicle body 110.

When both of the wheel supports 200 and 300 are in their base or retracted positions 206 and 306, respectively, their front and rear wheels are engaged with a support surface or object on which the toy vehicle 100 is located (see FIGS. 6-7). When both of the wheel supports 200 and 300 are in their extended positions 208 and 308, respectively, their front and rear wheels are also engaged with a support surface or object on which the toy vehicle 100 is located (see FIGS. 8-9). However, the toy vehicle body 110 is angled upwardly relative to the support surface because the front end 120 of the toy vehicle body 110 is spaced apart from the front ends of the wheel supports 200 and 300.

When only one of the wheel supports 200 and 300 is in its retracted position and the other wheel support is in its extended position (see FIGS. 10-11), the wheels of the extended position wheel support are engaged with a support surface and only the rear wheel of the retracted position wheel support is engaged with the support surface. The front wheel of the retracted position wheel support (which is wheel support 300 in FIGS. 10-11) is spaced apart from the support surface.

The drive system can cause the wheel supports 200 and 300 to move relative to the toy vehicle body 110. In one mode of operation, a first motor of the drive system can be actuated to move wheel support 200 between its retracted position 206 and its extended position 208, and a second motor of the drive system can be actuated to move wheel support 300 between its retracted position 306 and its extended position 308. The motors can be actuated to have the wheel supports 200 and 300 in the same positions at the same time, or in different positions from each other. One exemplary mode of operation is to move the wheel supports 200 and 300 back and forth between their retracted positions and their extended positions in an alternating manner, thereby creating a stomping-like appearance of the toy vehicle along a support surface.

Turning to FIG. 12, various components of the toy vehicle 100 are illustrated with the upper portion 112 of the toy vehicle body 110 having been removed to simplify the discussion. The lower portion 114 of the toy vehicle body 110 is shown with wheel supports 200 and 300 on opposite sides thereof. As best seen in FIGS. 12, wheel support 200 has a longitudinal axis 205 along which it extends, and wheel support 300 has a longitudinal axis 305 along which it extends.

When a wheel support is in its retracted position relative to the toy vehicle body 110, the longitudinal axis of that wheel support extends along a direction parallel or substantially parallel to the direction in which the longitudinal axis 128 of the toy vehicle body 110 extends. When a wheel support is in its extended position relative to the toy vehicle body 110, the longitudinal axis of that wheel support extends along a direction that is not parallel to the direction in which the longitudinal axis 128 of the toy vehicle body 110 extends. When both of the wheel supports 200 and 300 are in their retracted positions at the same time, or in their extended positions at the same time, their longitudinal axes extend directions that are parallel to each other.

Referring to FIG. 12, wheel support 200 includes wheels 260 and 270 rotatably mounted thereto. Front wheel 260 includes a body with a tread member 262 with projections 264 mounted to the body. Similarly, rear wheel 270 includes a body with a tread member 272 with projections 274 mounted to the body. Wheel support 300 includes similar wheels rotatably mounted thereto. In particular, front wheel 360 includes a body with a tread member 362 with projections 364, and rear wheel 370 includes a body with a tread member 372 with projections 374 mounted to the body.

The toy vehicle 100 also has an electronic system that includes a printed circuit board (PCB) 152 with a controller mounted thereto, a power source 154 (such as a rechargeable battery), and wiring 156 connecting the power source 154 and the two motors.

Referring to FIG. 13, the lower portion 114 of the toy vehicle body 110 has been removed. The housing 160 that contains the drive system components, including the two motors, is shown removed from the lower portion 114 of the toy vehicle body 110 and pivoted rearwardly. On opposite sides of the housing 160 are sleeves 162 and 164 that contain axles that are driven by the motors and that impart motion to the corresponding wheels and wheel supports. The axles in the sleeves 162 and 164 define the pivot points 214 and 314 for wheel supports 200 and 300, which are close to the rear ends 204 and 304 thereof. Front wheels 260 and 360 are rotatably mounted proximate to front ends 202 and 302 of wheel supports 200 and 300, respectively, and rear wheels 270 and 370 are rotatably mounted proximate to rear ends 204 and 304 of wheel supports 200 and 300, respectively. The pivot points 214 and 314 are proximate to the rear wheels 270 and 370, respectively, and the rear wheels 270 and 370 also rotate about the pivot points 214 and 314.

The wheel supports 200 and 300 include inner surfaces 210 and 310, respectively, Inner surface 210 has an inwardly directed projection 212 extending therefrom. Similarly, inner surface 310 has an inwardly directed projection 312 extending therefrom.

Turning to FIGS. 14-16, close-up views of different portions of toy vehicle 100 are illustrated. The upper portion 114 includes a ridged portion 130 that defines an arcuate slot 132 that has an upper end 134 and a lower end 136 (see FIG. 17). The projection 312 on wheel support 300 is inserted into slot 132 and can travel therealong. The length of the slot 132 limits the range of pivoting motion of wheel support 300 relative to toy vehicle body 110. The slot 132 operates as a limiter on the movement of wheel support 300.

In FIGS. 15 and 16, a plate 138 includes slot 132 formed therein. There are plates 138 on opposite sides of the toy vehicle 110 that are engaged by the wheel supports 200 and 300. In FIG. 15, the projection 212 on wheel support 200 is engaged with slot 132 and is shown at the upper end of the slot 132, which corresponds to the retracted position 206 of wheel support 200. In FIG. 16, the projection 212 is engaged with slot 132 and is shown at the lower end of the slot 132, which corresponds to the extended position 208 of wheel support 200.

Referring to FIG. 17, a side view of some components of toy vehicle 100 is illustrated. The plate 138 that has slot 132 formed therein is removably mounted to the toy vehicle lower portion 114. The lower portion 114 has a pair of notches or recesses 144 formed in opposite sides. Each notch 144 is sized to receive a plate 138 therein. The lower portion 114 includes side rails 146A and 146B with grooves that slidably receive tabs 142A and 142C formed on opposite sides of plate 138. The tabs 142A and 142C, as well as tab 142B, extend outwardly from an outer edge 140 of the plate 138. Also shown in FIG. 17 are channels 148 that receive the sleeves 162 and 164 of the drive system 150, which are discussed above.

Referring to FIGS. 18 and 19, an embodiment of a wheel for the toy vehicle 100 is illustrated. As shown in FIG. 18, rear wheel 270 includes a slot 278 in which a projecting portion 276 of tread member 272 is inserted to mount the tread member 272 to the body of the wheel 270. As shown in FIG. 19, the wheel 270 includes an inner surface 280 that has a central recess and a sleeve 282. Sleeve 282 defines an inner receptacle 284 that has several inner side surfaces 286. In this embodiment, the quantity of inner side surfaces 286 is six, but in different embodiments, the quantity of inner side surfaces may vary provided that the quantity matches the shape of the axle inserted in the sleeve 282.

Referring to FIG. 20-22, an embodiment of an axle for the toy vehicle according to the present invention is illustrated. The front end 202 of wheel support 200 has an axle 220 extending outwardly from its outer surface. The axle 220 includes a center portion or member 222 with a surrounding body portion 224 that has several outer sides or side surfaces 226. In this embodiment, the quantity of outer sides is six, which matches the quantity of inner sides surfaces of the sleeve on the wheel to be mounted to the axle 220.

The front axle of each wheel support 200 and wheel support 300 is driven by a set of gears that are engaged with that front axle and engaged with the corresponding rear axle of the particular wheel support 200 and 300. Thus, as the rear axle of a wheel support is rotated or driven, it engages one gear from a set of gears that extend along the inner cavity of the wheel support, and the rotation of the gears in the set is imparted to the corresponding front axle, causing it to rotate. It is to be understood that each of the front axle and rear axle for each of the wheel supports 200 and 300 are similarly structured, and that the sleeves formed on the inner surfaces of the wheels to be coupled to the wheel supports 200 and 300 are also similarly structured.

Turning to FIGS. 21-22, the front axle 220 includes several outer side surfaces at one end and a cylindrical distal portion 238 at its opposite end. Located therebetween is an engagement portion 228 that is formed of resilient portions 230A and 230B that are connected to the body of the axle 220 via oppositely located connectors 232 (only one of which is shown), thereby defining gaps 234A and 234B. On the outer surface of the resilient portions 230A and 230B are ridges or teeth 236A and 236B, respectively.

A drive member 240 is slidably mounted onto the axle 220 via a central opening 254 that receives the distal portion 238 of axle 220. The drive member 240 includes a body portion 242 that has an inner surface 244 defining teeth 246 therealong. The drive member 240 also includes a body portion 248 with a smaller outer diameter than body portion 242. Body portion 248 has an outer surface 250 that have teeth 252 as well.

In the toy vehicle 110, teeth 252 on outer surface 250 are engaged with the teeth of one of the gears that are located between the front axle and the rear axle in wheel support 200. As the rear axle is rotated, each of the gears in the set of gears between the front axle and the rear axle rotates, and the drive member 240 is rotated. Rotation imparted to the drive member 240 rotates the axle 220 because of the engagement of ridges 236A and 236B with teeth 246. It is to be understood that the discussion above as to the operation of the front axle 220 of wheel support 200 applies in a similar manner to the operation of the front axle of wheel support 300 as well.

In the illustrated embodiment, the drive assembly of the toy vehicle functions similar to a tank drive system. The toy vehicle drive assembly is configured such that varying the power applied to each of the rear wheels results in the toy vehicle performing a turning motion. By applying more power to one rear wheel versus the other rear wheel results in the toy vehicle turning in the direction of the lower power rear wheel.

The programming run by the CPU sets power percentages to achieve this tank drive style of turning of the toy vehicle. In one exemplary operation, applying 100% power to the left rear wheel in the forward direction while applying 18% power to the right rear wheel in the forward direction causes the toy vehicle to the right while driving forward without lifting either of the wheel supports or the front wheels. In other embodiments, the CPU can be programmed to control the motors using different power percentage levels. The percentages are tied to the gripping characteristics of the wheels and tire grips coupled to the wheels.

During operation of the toy vehicle, as the differential in the power applied to the rear wheels increases, the rate of turning of the toy vehicle also increases. In one embodiment, the rate of turning can be set to be proportional to the power differential applied to the rear wheels.

Another operation of the toy vehicle involves at least one of the motors operating in a reverse direction. In one exemplary implementation, when the left rear wheel is driven forward at 100% power and the right rear wheel is driven rearward at 100% power, the toy vehicle will make the most extreme turn possible, which is a 360° spin in place. In other implementations, the toy vehicle can make various turns based on applying power to the left rear wheel and to the right rear wheel in opposite directions.

The front ends 202 and 302 of the wheel supports 200 and 300 are independently forced downwards when the corresponding rear wheel coupled to the respective wheel support is driven in the reverse direction. The range of travel of the wheel support is limited by the travel of the projection on the wheel support in the corresponding slot of a limiter on the toy vehicle. When one of the wheel supports is driven downward, the other wheel support is raised or lifted in the air. This movement pushes up the toy vehicle body 110 until its travel is stopped. In one mode of operation, alternate wheel supports and front wheels will raise if the toy vehicle 100 is turning to the left or to the right at or above a set percentage rate.

The two motors of the toy vehicle 100 can alternate which is driven in reverse while the other motor is driven forward. When the reverse/forward alternating driving is done in short timing intervals, a stomping-like action of the toy vehicle 100 due to the movements of the wheels supports 200 and 300 is performed. In one mode of operation, the toy vehicle 100 can appear to walk in place when the front wheels and the wheel supports 200 and 300 are alternately lifted off a support surface. This alternating movement of the wheel supports 200 and 300 is performed when controller button 508 is pressed by a user.

In another mode of operation, the toy vehicle 100 can be driven into a vertical position. When the toy vehicle 100 is reversed at its maximum speed, the user can push the power stick 504 to full forward power. The result is that the toy vehicle 100 will rotate and the front wheels will be up in the air in a vertical orientation. In this mode, the toy vehicle 100 can spin 360° by running the two motors in opposing directions.

As discussed above, in one embodiment, the toy vehicle 100 has four driven wheels, which helps with the toy vehicle's driving ability on rough surfaces and climbing onto objects and obstacles. It is to be understood that the various modes of operation and actions described above are not limited to the four wheel drive functionality. All of the foregoing operating modes and actions can be achieved by a different embodiment of a toy vehicle in which only the rear wheels of the toy vehicle are driven.
