Description:

BACKGROUND OF THE INVENTION

[0001] The present invention relates to remote control toys and, more specifically, to a remote control toy car and bubble blower arrangement.

[0002] Various motor-driven toy cars and remote-controlled toy cars are commercially available. There are also known toy cars equipped with bubble blower means. These toy cars include a first type provided with a bubble-blowing ring, and a second type equipped with a bubble-blowing ring and a vane wheel. However, these toy cars with bubble blower means are not motor-driven.

SUMMARY OF THE INVENTION

[0003] It is the main object of the present invention to provide a remote control toy car, which automatically opens and closes the hood of the toy car, and blow bubbles when the hood is opened. The present invention comprises a chassis equipped with front wheels and rear wheels and covered with a car body and a pivoted hood, a reciprocating bar adapted to open/close the hood, a bubble-blowing ring, which is moved with the hood and dipped in the solution in a solution container when the hood is closed, a cam wheel controlled to reciprocate the reciprocating bar, a van wheel adapted to blow air through the bubble-blowing ring when the hood is opened, a gear box adapted to rotate the can wheel and the rear wheels, and a motor controlled by a remote controller to rotate the vane wheel and the gear box.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0011] Referring to FIGS. from 1 through 7, the invention is generally comprised of a vane wheel 2, a motor 4, a gear box 13, a cam wheel 10, a reciprocating bar 19, a bubble-blowing ring 24, a chassis 30, a car body 32, a hood 33, two front wheels 29, and two rear wheels 31.

[0012] The vane wheel 2 is mounted in a wind box formed of two symmetrical shells 1 and 6, and coupled to the motor 4. The shells 1 and 6 are fastened together by screws 9. When fastened together the shells 1 and 6 form an air nozzle 27 at its front side. The motor 4 is mounted in the rear side of the chassis 30, having a first output shaft 3 coupled to the vane wheel 2 and a second output shaft 5 fixedly mounted with a pinion 8. The gear box 13 is comprised of two symmetrical shells 14, and coupled between the pinion 8 and a rear wheel axle 15. One of the shells 14 has a plurality of mounting holes 16, which receives respective mounting rods 7 of one shell 6 of the aforesaid wind box. The rear wheel axle 15 is transversely mounted in the rear side of the chassis 30 to support the two rear wheels 31. A transmission shaft 12 is coupled to the gear box 13 at the top. The cam wheel 10 is connected to the transmission shaft 12, having an annular sliding groove 17 extended around the border area thereof at one side. The reciprocating bar 19 is inserted into an oblique track 17 at one side of the gear box 13, having a protruded rod 21 disposed at one side of the rear end thereof and inserted into the annular sliding groove 17 of the cam wheel 10. When starting the motor 4, the gear box 13 is driven to rotate the rear wheel axle 31 and the cam wheel 10, to further rotate the rear wheels 31 and reciprocate the reciprocating bar 19 in the tack 17. A stop block 16 is provided at one side of the oblique track 17 to stop the reciprocating bar 19 from falling out of the oblique track 17. The car body 32 is covered on the chassis 30. The front side of the car body 32 curved downwardly forwards. A solution container 25 is mounted in the front side of the car body 32. The solution container 25 holds a solution 26 for blowing bubbles. The hood 33 is pivoted to the car body 32 by a pivot 35, and covered on the front side of the car body 32. A pivot 34 pivots the bubble-blowing ring 24 to the inside of the hood 33. The car body 32 has a through hole 22 for the passing of the reciprocating bar 19. The hood 33 has a stop block 23 disposed in contact with the front end 20 of the reciprocating bar 19. When starting the motor 4 to rotate the rear wheels 31 and to simultaneously reciprocate the reciprocating bar 19, the hood 33 is moved with the reciprocating bar 19 between the open position and the close position. When moving the hood 33 to the close position, the bubble-blowing ring 24 is lowered with the hood 33 and dipped into the solution 26 in the solution container 25. When moving the hood 33 to the open position, the bubble-blowing ring 24 is lifted from the solution container 25 and aimed at an air hole 28 on the car body 32 to which the air nozzle 27 is connected, and at the same time the vane wheel 2 is rotated by the motor 4 to blow air through the air nozzle 27 toward the bubble-blowing ring 24, and therefore bubbles are produced. Further, a remote control circuit board 37 is installed in the chassis 30. The remote control circuit board 37 comprises a receiving antenna 36 adapted to receive control signal from the transmitting antenna 42 of a controller 41. The front wheels 29 are mounted on the front side of the chassis 30. The controller 41 controls the steering direction of the front wheels 29. The controller 41 comprises a forward-backward control button 44, and a left-right control button 43 for controlling the remote control toy car to move forwards or backwards, or to change its steering direction. Further, a battery box 39 is installed in the chassis 30 to hold a battery 40. An on/off switch 38 is installed in the rear side of the chassis 30 and connected between the battery box 39 and the remote control circuit board 37 for power on/off control.

[0013] While only one embodiment of the present invention has been shown and described, it will be understood that various modifications and changes could be made thereunto without departing from the spirit and scope of the invention disclosed.
