It is set in the state. Further, the transfer table 20 has a gear box 25 integrally formed on one side of the main body 21, and further has a cylindrical portion 26 formed on one side thereof. A gear train 24 is built into the gearbox 25 for transmitting the rotational force from the input gear 24a of the transfer table main body 21 to a small gear 27 rotatably protruding from the center of the front part of the cylindrical part 26. (The illustration of the intermediate gear is omitted in FIG. 3. The cylindrical part 26 is rotatably supported on its outer periphery by the bearing part 15b of the movable arm 15, and has the above-mentioned bearing part in the front part. A stopper 26a that abuts against a part of the cylindrical portion 15b and limits the rotation of the cylindrical portion 26 to approximately 180 degrees is provided protrudingly, and a ring-shaped gear 28 is further carved on the outer peripheral end of the front portion. The transfer table 20 is rotatably supported by the movable arm 15 through a cylindrical portion 26 by approximately 180 degrees.
The small gear 27 of the transfer table 20 is always engaged with the semicircular gear 13 of the cylindrical body 12, and the ring gear 28 is engaged with the quarter circular gear 14 when the transfer table 20 is rotated by a predetermined angle by the movable arm 15.

is being driven. A gear 32 is concentrically protruded from the outer side of the rear wheel 31, and a gear 32 is provided on the outer side of the rear wheel 31.
When transferred to the seat, the rack 23 and the input gear 24a mesh with each other. Further, on the bottom surface of the running body 30, there are two leaf spring-shaped input terminals 33 that contact the output terminal 29 of the running body main body 21 and charge the battery.
There are several. Note that the shape of the traveling body 30 can also be modeled after a vehicle other than an automobile, an animal, or the like.

41 and 42 are the approach orbit and the advance orbit,
The ends of the track and the transfer platform body 21, which are separated from each other
One approach track 41 allows the traveling body 30 to enter the transfer table main body 21, and the other advance track 42 allows the traveling body 30 to advance from the transfer table main body 21. It's tight. In addition,
The approach track and the exit track in the present invention not only mean short intermediate tracks as in the embodiments, but also include the approach side and exit side tracks of the divided main track.

Next, the operation of this embodiment will be explained.

In a state where the transfer table main body 21 is connected to one of the approach tracks 41, the traveling body 30 is connected to the approach track 41.
When it is transferred to the transfer table main body 21, the traveling body 3
0 is prevented from advancing by the stopper 21a.
At this time, the gear 32 protruding from the rear drive wheel 31 of the traveling body 30 meshes with the input gear 24a protruding from the inner rear part of the transfer table main body 21, and rotates the input gear 24a while causing the rear wheel to slip. . This rotational movement of the input gear 24a is controlled by the gearbox 25.
The signal is transmitted to a small gear 27 protruding from the center of the cylindrical portion 26 via a gear train 24 inside. Since the small gear 27 meshes with the semicircular gear 13 of the cylinder body 12, its rotational motion causes it to roll on the semicircular gear 13,
As a result, the transfer table 20 is horizontally rotated clockwise about the movable arm 15 while resisting the tension spring 16. That is, the transfer table 20 gradually rotates horizontally and moves clockwise by the driving force of the traveling body 30.

When the pinion 27 rolls on the semicircular gear 13 at an angle of approximately 90 degrees and the transfer table 20 becomes approximately vertical (state A in FIGS. 1 and 2), the transfer table 20 becomes vertical. A ring-shaped gear 28 at the front of the cylindrical part is a quarter-circle-shaped gear 1 provided on the upper right peripheral surface of the rear part of the cylindrical body 12.
meshes with 4. In the state where the ring gear 28 and the quarter circular gear 14 are in mesh, the small gear 27
When rolling on the semicircular gear 13, the cylindrical portion 26,
That is, the transfer table 20 is the bearing part 1 of the movable arm 15.
5b, the traveling body 30 rotates vertically in the clockwise direction when viewed from the ring gear 28 side, and performs a half turn to perform a direction changing motion of the traveling body 30. As a result, the transfer platform 20 moves toward the other advancement track 42 while performing a direction change motion of the traveling body 30 by twisting from horizontal rotation to vertical rotation (B in FIGS. 1 and 2). situation).
When the small gear 27 rolls over approximately 180 degrees on the semicircular gear 13, the ring-shaped gear 28 of the cylindrical portion 26
is also rotated approximately 180 degrees by the quarter-circular gear 14, and the transfer table 20 connects with the other advance track 42 with the direction of the traveling body 30 changed by 180 degrees (the first
(C state in Figure 2 and Figure 2).

When the transfer table 20 is positioned to connect with the other advancing track 42, the rotation of the small gear 27 that meshes with the semicircular gear 13 is prevented, so the rotation of the gear train 24 is also prevented, and the transfer table main body 21 is prevented from rotating. input gear 24
a will function as part of the rack 23. Therefore, the traveling body 30 is given a strong forward force by the meshing of the gear 32 protruding from the rear drive wheel 31 with the input gear 24a and the rack 23, and advances over the stopper 21a to the advance track 42.

From one approach track 41 side to the other advance track 42
Due to the rotational movement of the transfer table 20 to the side, the traveling body 30 takes a sideways posture and a forward tilted posture on the transfer table main body 21, but is held by the traveling guide walls 22 and stoppers 21a on both sides and does not fall. There's nothing to do. Also, during this time, the input terminal 33 of the traveling body 30 is
It continues to be in contact with the output terminal 29 of the transfer table main body 21 and charges the battery built into the traveling body 30. In this way, if the battery of the traveling body drive source is charged while the traveling body 30 is being transferred, there is no need to stop the traveling body for charging.

When the traveling body 30 runs away from the transfer table main body 21,
Since the force that tries to rotate the small gear 27 is released, the movable arm 15 is pulled by the tension spring 16, and the transfer table 20 is moved horizontally and vertically by about 180 degrees counterclockwise, contrary to the above. Rotate. As a result, the transfer platform 20 is in the initial state, that is, the approach trajectory 4
It is returned to the position where it connects with 1. Note that the start of this return operation can be controlled by using a locking hook or the like on the traveling body 3.
It is also possible to perform the process after 0 has surely moved to the advance track 42.

As described above, according to the present invention, the traveling object that has been transferred from the approach track side is moved by twisting and rotating movement that combines the vertical and horizontal rotations of the transfer table at the appropriate dividing point of the track that has been combined into the desired shape. Since the moving body can be moved to the advancing track side divided into different directions by changing direction, the moving movement of the moving body changes, making play with the moving toy more enjoyable for children and the like. Furthermore, since the traveling body is transported by two-dimensional movement through horizontal and vertical twisting rotations, the installation space can be narrowed and unnecessary enlargement of the toy can be prevented.

Furthermore, since the transporting operation of the traveling body is performed using the traveling driving force of the traveling body without providing a battery or the like, it gives a mysterious feeling to young children and the like, and can further attract interest.
