Description

[Detailed Description of the Invention] The present invention relates to a mystery set traveling car toy whose mystery wheel device can be freely raised or lowered.

When the mystery wheels are being driven and the vehicle is running, children may ignore the driving of the mystery wheels and try to force the vehicle to proceed in the desired direction, or they may press the vehicle from above to prevent the mystery wheels from driving. The mystery wheel device has the disadvantage of being easily destroyed due to excessive handling.

Taking this into consideration, this proposal is designed so that the mystery device can be raised or lowered with a simple device and operation. Once raised and separated from the floor, children, etc. can freely move the vehicle body in the desired direction. This was done to prevent the mystery wheel device from being destroyed even if the car body is forcibly pressed from above.

To explain the present invention with the drawings, 1 is a mystery wheel device unit in which wheels 3 are installed at both ends of an axle that is driven in relation to the lower end of a rotating vertical shaft 2; An expansion coil spring 7 is wound around the intermediate vertical shaft 2 and can press the mystery wheel device downward at all times, and 7 is an actuating member that is pivotally supported 8 on the machine frame at a proper place, and a vertical shaft is attached to the tip of the arm piece 9 at one end. 2 is provided with an L-shaped retaining piece 11 that engages and disengages from the jaw of a locking part 10 provided at the upper end of 2, 12 is a connecting rod whose front end is connected to the other end of the operating member 7, and 13 is a bottom piece that connects to the vehicle body plate. It is an L-shaped operating rod with a pivot 14 on the top, and the rear end of the connecting rod 12 and the retraction spring 15 are connected to the upper end, and the lower end of a leg rod 17 having a push button 16 at the upper end is supported on the upper surface of the rear end of the bottom piece. 18 is the car body plate, 1
9 is the rear wheel, 20 is the front wheel, and front and rear wheel axles 21.22
are loosely supported by bearings 23 on the upper surface of the vehicle body plate.

The present invention is constructed as described above, and in particular, the mystery wheel device part 1 can be raised and lowered together with the rotating vertical shaft 2 as described above, and as shown in FIG. leaves the floor, the prime mover is activated, and the rotary vertical shaft 2 is rotated, and the vehicle body runs under the drive of the mystery wheel device section.This point is similar to a conventional mystery wheeled vehicle.Mystery wheel device If you want to raise it above the floor while the part is descending as shown in Fig. 2, manually press up the coil spring 4 from the bottom side of the mystery wheel device part 1 while compressing the coil spring 4, and the rotating vertical shaft 2 will also move at the same time. Since the locking part 10 at one end of -4 is automatically locked to the L-shaped engaging piece 11 located on the rising path, the mystery wheel device is supported in the raised position, that is, the state shown in FIG. 3. Instead, the front wheels 20 are in contact with the floor, and the vehicle body is supported by the front and rear wheels, so it can move freely regardless of the mystery wheels, and even if the vehicle body is pressed from above. Since there is no load on the mystery wheel, there is no risk of it being destroyed.If you want to lower the mystery wheel device that has been lifted off the floor and onto the floor again, pull back the push button 16. When the L-shaped operating rod 13 is rotated rearward as shown in FIG. 4 by pushing down against the action of the spring 15, the operating member 7 associated with the operating rod 13 is rotated around the pivot support 8 using the linking rod 12. The mystery wheel device part 1 is rotated as shown in FIG. At this time, the vertical shaft 2 and the coil spring 4 lower each other to the state shown in FIG. That's what I do.

As mentioned above, in this case, the mystery wheel device part 1 can be easily pushed up and supported in a fixed position away from the floor, so that children and the like will not destroy the mystery wheel device part by forceful handling. In addition, since the vehicle can be moved freely using only the front and rear wheels instead of the mystery wheels, the vehicle can be used for a long time, and it is easy to switch to running using the mystery wheels, so children etc. This has the effect of allowing you to switch at your will and enjoy the driving operation as you wish.
