The roll bar / antenna 228 is properly connected to the circuit board 232 and transmits and receives a signal between a remote controller (described below) and the circuit board 232 to control the operation of the toy car 10.

The linear drive assembly 300 includes a drive motor 310. With particular reference to FIGS. 2 and 5, the drive motor 310 is mounted at opposite ends of the first motor mounting plate 312 and the second mounting plate 314 (see also FIG. 6). The drive motor 310 is suitably a bidirectional driveable electric motor of the type generally used in toy cars. The motor 310 engages the shaft 256 via a drive gear train 320 (FIG. 2). The drive gear train 320 includes a pinion 322 fixed to an outer shaft (not shown) of the drive motor 310. The pinion 322 interlocks with the combination damping gear 324 together with the integrally formed spur gear 326, and the spur gear 326 interlocks with the drive gear 328 fixedly attached to the shaft 256. . Therefore, the motor 310 may drive the front wheel assembly 250 in either the front or rear direction through the drive gear train 320. Other drive train arrangements may be used in the form of belts or other forms of power transmission. This arrangement disclosed herein is not meant to be limiting.

A spring-loaded overturn mechanism, denoted "400" in FIG. 6, is mounted to the toy vehicle 10. The rollover mechanism 400 is operatively coupled to both the front chassis 100 and the rear chassis 200. In operation, the overturn mechanism 400 flips or rotates the front chassis 100 360 degrees with respect to the rear chassis 200 on the longitudinal axis 434 of the toy car 10.

In the preferred embodiment shown in FIGS. 1-10, the rollover mechanism 400 includes three sub-assemblies: triggering mechanism 410 (FIG. 7), rotational drive mechanism 430 (FIG. 8), and Spring protection mechanism 460 (FIGS. 9 and 10).

With particular reference to FIGS. 6 and 8, the rotation drive mechanism 430 includes a main drive shaft 432 with a longitudinal axis 434. The spindle 432 is supported at the rear end by a spindle rear bushing 436 which is connected to the second bottom housing plate 220 via a spindle rear support member 222 (FIG. 2). The juice spring 440 surrounds a portion of the main shaft 432. The juice spring 440 is preferably a torsion spring wound several times the spring wire. The juice spring 440 is preferably preloaded (ie, wound two or three times) to provide a minimum torque or starting torque to the spindle 432. When the overturn mechanism 400 is actuated by winding the juice spring 440 in advance, the juice spring 440 is loosened in a sufficient linear manner (ie, providing sufficient linear force to the spindle 432). Sufficient linear force from the juice spring 440 provides a relatively constant flipping motion when the overturn mechanism 400 is active.

Preferably, the spindle bushing 438 is sleeved around the spindle 432 between the juice spring 440 and the spindle 432. The spindle bushing 438 prevents the juice spring 440 from rubbing on the spindle 432 and prevents the spindle 432 or juice spring 440 from being excessively worn. The spindle bushing 438 also prevents the juice spring 440 from being tied to the spindle 432 when the juice spring 440 is loaded.

A spring holder 442 is mounted on the main shaft 432 and one end of the juice spring 440 is fixed to the spring holder 442. Opposite ends of the juice spring 440 are properly supported by the spring support member 226 to maintain torsion on the juice spring 440.

The spring holder 442 is adjacent to a winding gear 448 fixedly attached to the spindle 432. The winding gear 448 is integrally formed with the winding gear spring 446. A portion of the winding gear base 444 is adjacent to the shaft disk 450 and a torsion damper spring wound about the main shaft 432 disposed between the winding gear base 444 and the shaft disk 450. 446 is provided.

As can be seen through FIG. 4, the shaft disk 450 is provided with a protruding element for forming the shaft disk stop 456 on the rear surface of the shaft disk 450. As will be described later, this protruding axle disc stop 456 interacts with the stopper member 424 and the over-wind protection arm 468 (FIG. 3), which are part of the respective function of the triggering mechanism 410 and the spring protection mechanism. Crazy

A chassis alignment disk 452 is suitably mounted on the spindle 432 between the front chassis 100 and the rear chassis 200. The chassis alignment disk 452 maintains axial alignment of the front and rear chassis portions 100, 200. Maintaining the axial alignment of the front and rear chassis portions 100, 200 is such that when the front chassis 100 rotates about the longitudinal axis 434 of the toy car 10 and the main shaft 432, the front chassis Prevents 100 from contacting the rear chassis 200.

The axis 432 extends properly forward from the rear chassis 200 and is received within the pivot block 454. The pivot block 454 contacts both the first upper housing plate 110 and the first bottom housing plate 120 of the front chassis 100 to allow the front chassis 100 to engage the main shaft 432. . Suitably, the pivot block 454 can rotate between about 0 degrees and 15 degrees (± 7.5 degrees) inside the front chassis 100 so that the toy car 10 is not on a flat surface. Compensates for any misalignment between the front and rear chassis portions 100, 200.

3 and 7, the triggering mechanism 410 includes a shaft pinion 412 fixed to the rear drive shaft 256. The shaft pinion 412 cooperates with the actuator gear 414. The actuator gear 414 has an actuator gear pin 416 on its inner surface that abuts an actuator trigger 418 mounted adjacent to the actuator gear 414. The actuator trigger 418 cooperates with a spring-loaded sliding plate 420. The sliding plate 420 is biased to the forward position 420a by the spring 428 (shown in solid lines in FIGS. 1 and 5 and in dashed lines in FIG. 7). An arm extending from the sliding plate 420 is pivoted in cooperation with the first swing door member 422. Preferably, in the untriggered position 422a, the first swing door member 422 cooperates with the stopper member 424. More preferably, in the untriggered position, the stopper member 424 is in its position 424a and in conjunction with the shaft discontinuity 456 on the shaft disk 450 (FIG. 4), the tension of the juice spring 440. Hold the axial disk 450 (including other components of the rotational drive assembly 430) in its position with respect to. The stopper member spring 426 is connected with the stopper member 424. The operation of the triggering mechanism is described below.

3, 9 and 10, the spring protection mechanism 460 includes a crown gear 462 that cooperates with the winding gear 448 (FIGS. 2, 6 and 8). The crown gear 462 includes a cam surface 464 on the underside of the crown gear 462. An overwind protective arm 468 is mounted closest to the crown gear 462 and the axial disk 450. As described below, the over-wind protection arm 468 is biased to engage the axial disk stop 456 by the cam surface 464 on the crown gear 462, and the juice spring 440 is fully wound. In this case, the main spring 440 is no longer wound.

The spring protection mechanism 460 (FIGS. 9 and 10) further includes elements for preventing the load previously hung on the juice spring 440 (i.e., under-wind protection). In a preferred embodiment, the cam groove 466 located below the crown gear 462 extends from the second swinging door member 470 and through the second swinging door through a pin 472 moving inside the cam groove 466. In conjunction with the member 470. As described below, the second swinging door member 470 is biased to interlock with the stopper member 424, alternately biasing the stopper member 424 at position 424a, Rotation prevents the drive from interlocking with the axial disk stop 456, thereby preventing the axial disk 450 from loosening (more loosening).

In operation, the user holds the rear chassis 200 in his hands while the front chassis 100 is twisted or rotated clockwise (backward facing forward) relative to the longitudinal axis 434 of the main shaft 432. Grip and manually wind the rotational drive mechanism 430. Winding the rotation drive mechanism 430 puts a load on the juice spring 440. In a suitable embodiment, the rotation drive mechanism 430 is designed to allow the user to rotate the rotation drive mechanism 430 completely three times (1,080 degrees). Those skilled in the art will appreciate that the rotation drive mechanism 430 may be optionally designed to allow a user to wind or load the rotation drive mechanism 430 more than three times or less than a full revolution. The rotation drive mechanism 430 includes a tactile organ that “clicks” when rolled up so that the user can record the number of times the rotation has been completed.

In a suitable embodiment, when the toy car 10 moves in the opposite direction, the triggering mechanism 410 is activated and the shaft disk 450 from interlocking with the stopper member 424 described above with reference to the triggering mechanism 410. ) And the axial disc stop 456 are released, and the rotation drive mechanism 430 has a front chassis portion 100 of the toy car 10 with a rear chassis portion 200 with respect to the longitudinal axis 434 of the main shaft 432. To flip or rotate about 360 degrees. The toy car 10 is landed with wheels 150 and 250 and can move or reverse direction.

If you want to keep the toy car 10 moving in the opposite direction, the triggering mechanism 410 and the rotation drive mechanism 430 keep the front chassis portion 100 turned over until the load is released to the rotation drive mechanism 430. (I.e., as will be described later, the rotation drive mechanism 430 is released until the load on the juice spring 440 reaches the initial load state and prevents the spring protection mechanism 460 from further loosening). Once the rotational drive mechanism 430 is released, the toy car 10 may drive backward (or otherwise) in a steady state (ie, without flipping).

More specifically, the spring-loaded overturn mechanism 400 is such that when the toy car 10 drives backwards and the rear wheel assembly 250, the front drive shaft 256 and the shaft pinion 412 rotate, the triggering mechanism ( 410). Rotation of the shaft pinion 412 rotates the actuator gear 414. As the actuator gear 414 rotates, the actuator gear pin 416 on the actuator gear 414 interlocks with the spring loaded sliding plate 420 and with the actuator trigger 418 that pushes backwards, and the sliding The plate 420 moves from the first position 420a (dotted line in FIG. 7) to the second position 420b (solid line in FIG. 7). The sliding plate 420 is pivotally engaged with the first swing door member 422 from the first position 422a (dotted line display) to the second position 422b (solid line mark). As the first swing door member 422 pivots backward, the stopper member 424 is released in linkage with the first swing door member 422. The stopper member 424 is pivoted from the first position 424a (dotted line) to the second position 424b (solid line), and with the axial disk stop 456 (shown in FIG. 4) on the axial disk 450. Unlocked in conjunction with When the axial disk stop 456 and the axial disk 450 are released in conjunction with the stopper member 424, the torque provided by the juice spring 440 on the main shaft 432 is the axial disk 450, the main shaft 432, and the front. Pivot block 454 and front chassis 100 are flipped or rotated about longitudinal axis 434 of main shaft 432. The stopper member spring 426 biases the stopper member 424 back to position 424a, and the stopper member 424 rotates the axial disk stop as the shaft disk 450 rotates through one complete rotation. 456 again stops rotation of the rotational drive mechanism after one complete cycle (360 degrees). The damper spring 446 provides a damping force or cushion to reduce the forces on the various components of the rotation drive mechanism 430 from the torque generated by the rotation of the front chassis 100, ie to prevent damage to the components. to provide.

The spring protection mechanism 460 operates to prevent both the juice spring 440 from winding too much or too little. Manually winding the front chassis 100 relative to the rear chassis 200 when the user rotates the front chassis 100 with respect to the rear chassis 200 causes the spindle 432 to operate under the pivot block 454. Make it rotate Repeated rotation of the main shaft 432 causes the winding gear 448 to rotate in conjunction with the crown gear 462. In a suitable embodiment, the gear ratio of the winding gear 448 to the crown gear 462 is controlled by three complete manual rotations of the front chassis 100 with respect to the rear chassis 200 to fully wind the juice spring 440. The crown gear 462 is such that the crown gear cam surface 464 rotates to the point at which it interlocks with the over-wind protection arm 468, wherein the over-wind protection arm 468 is the rear of the shaft disk 450. Toward the second position 468b from the first position 468a. If the user wants to wind the toy car 10 further, the over-wind protection arm 468 cooperates with the axle disk stop 456 so that it no longer winds. Therefore, the juice spring 440 is not excessively wound. When the overturn mechanism 400 is in operation, the crown gear cam surface 464 rotates without interlocking with the over-wind protection arm 468, allowing the user to rewind the rotation drive mechanism 430.

The spring protection mechanism 460 further acts to prevent the first loaded load of the juice spring 440 from releasing (ie, loosening protection), which is done when assembling the toy car 10. Crown gear cam groove 466 (see FIGS. 3 and 9) engages pin 472 on second swinging door member 470. When the front chassis 100 rotates with respect to the rear chassis 200, the crown gear 462 rotates under the action of the winding gear 448 on the main shaft 432. In a suitable embodiment, the front chassis 100 rotates three cycles from the fully wound state, with the second swinging door 470 from the first position 470a to the second position 470b (see FIG. 9). The crown gear 462 rotates to the point of movement (via the movement of the pin 472 in the crown gear cam groove 466). In this second position 470b, the second swinging door 470 prevents the stopper member 424 from interlocking with the axial disk stop 456 (ie, out of position 424a). Thus, the shaft disk 450 is no longer rotated and the rotation drive mechanism 430 is no longer loosened. When the rotation drive mechanism 430 is wound, the crown gear 462 rotates and the second swinging door 470 stops as the pin 472 follows the crown gear cam groove 466. Out of linkage with (424).

The vehicle 10 may be made of plastic or other suitable material such as metal or composite material. Through this specification, those skilled in the art will understand that various changes are possible, such as making components of the toy vehicle 10 smaller or larger than the components shown by way of example. The car 10 may be reversed while moving on the ground or while floating in the air (eg, jumping up and jumping).

The toy car 10 is suitably controlled via a radio (radio) signal from a remote controller. However, other types of controllers may be used, including wireless controllers and other wireless controllers (eg, infrared, ultrasonic and / or voice-aware controllers, etc.).

A suitable embodiment of the remote controller 500 for use in the present invention is shown in FIGS. 11 and 12. The remote controller 500 includes a multi-part housing having a left hand and a right hand 510, 520. Upper and lower housings 516 and 528 and bottom housings 512 and 524 are formed in the left and right hand parts 510 and 520, respectively. The left button 514 is appropriately disposed on the left hand portion 510, and the right locking switch 526 is disposed on the right hand portion 520. An antenna 530 is included to receive (or transmit) a signal from the remote controller 500 (and / or to the remote controller).

As shown in FIG. 11, the left hand and right hand parts 510 and 520 are pivoted properly relative to each other. The switch 540 is properly disposed inside the remote controller 500. The switch 540 responds appropriately to the pivot state of the left hand portion and the right hand portions 510 and 520. The remote controller 500 processes inputs from the switch 540, the left button 514, the right lock switch 526, and the like, and includes a circuit unit 550 for transmitting and receiving signals with the toy vehicle 10. Suitably, each of the switches 540, left button 514, and right lock switch 526 is operated or a combination thereof to control the operation of the toy car 10 and the rollover mechanism 400.

In a suitable embodiment, the remote controller 500 is designed to actuate the drive motor 310 of the toy car 10 by pressing the left button 514 to move the toy car forward. The right lock switch 526 is pressed to operate the motor in the steering assembly 170 to steer the toy car 10. When the switch 540 is operated by pivoting the left hand part and the right hand part 510 and 520 with respect to each other, the driving motor 310 is driven in the reverse direction to operate the overturn mechanism 400.

It will be appreciated that the remote controller 500 can be formed from a variety of materials and can be modified to include additional switches and / or buttons. It will also be appreciated that various other types of controllers, including standard, non-pivoting controllers, and the like, can be used to control the operation of the toy car of the present invention and the operation of the rollover mechanism.

Those skilled in the art will understand that although the roll over mechanism 400 operates in the present specification, when the toy car 10 reverses, other modes of operation may be used. For example, the rollover mechanism works when the vehicle is moving forward, or by operating a disconnect switch on the remote control, or when the toy car 10 ignores the actuator by the sensors and circuitry on the toy car 10. can do.

Although the present invention has been described in the present invention as a four-wheel embodiment, the present invention is also applicable to a three-wheeled vehicle, or a vehicle having four or more wheels.

It will be apparent to those skilled in the art that modifications may be made to the embodiments described above without departing from the broad inventive concept. Accordingly, the present invention is not limited to the specific embodiments described and may vary within the spirit and scope of the invention.
