0 in a spiral motion upwards. At this time, the guide cylinder 23 and the guide rod 14 are coupled together to prevent the transfer table 20 from tilting and keep it horizontal. In addition, 28
is a spring that is threadedly engaged with the guide rod 14 at the upper part of the guide tube 23, and is compressed when the transfer table 20 reaches a position where it connects with the upper track 32, and functions to spring the guide tube 23 downward. Further, reference numeral 21a denotes a stopper projecting from the front of the loading surface of the transfer table main body 21, and is formed so as to be elastically resilient by a leaf spring 21b.

The upper track 32 is formed on the top surface of a truncated cone-shaped stand 33, and the upper track 32 of this stand 33
A locking hook 34 is provided protrudingly on the entry side of the holder. The locking hook 34 is constantly urged upward by a tension spring 35, and engages with the lower edge of the transfer table main body 21 when the transfer table main body 21 reaches a position where it connects with the upper track 32. The transfer table 20 is locked.
Furthermore, the locking hook 34 is connected to a bridge 36 that is continuous with the upper track 32 and a link mechanism 37 provided inside the platform 33.
There is a traveling body 40 on the bridge 36.
When the bridge 36 runs and lowers the bridge 36, the link mechanism 37 disengages from the lower edge of the transfer table main body 21 and releases the transfer table 20. Note that the above-mentioned bridge 3 is used as a release member for releasing the lock of the transfer table 20.
In addition to 6, various other types can be used, such as a claw protruding from the bottom surface of the upper raceway 32 or an abutment bar protruding from the side of the upper raceway 32.

The traveling body 40 is a self-propelled vehicle having the shape of a car, and is equipped with a drive source such as a battery, a dry battery, or a mainspring inside, and runs with rear wheels 41 as driving wheels. A small gear 42 is protruded from the outside of the driving rear wheel 41, and is configured to mesh with the gear 26 and transmit rotation when the traveling body 40 is transferred to the transfer table main body 21. Note that the shape of the traveling body 40 can be modeled after a vehicle other than a car, an animal, or the like.

Next, the operation of this embodiment will be explained.

When the moving body 40 is transferred from the lower track 31 to the transfer platform main body 21 in a state where the transfer table 20 is connected to the lower track 31, the moving body 40 is stopped from advancing by the stopper 21a. At this time,
A small gear 42 protruding from the rear drive wheel 41 of the traveling body 40 meshes with a gear 26 protruding from the rear of the other side of the transfer table main body 21, and rotates the gear 26 while causing the rear wheel 41 to slip. . This rotation of gear 26 is transmitted to drive gear 27 via intermediate gear 26a and shaft 27a. As a result, the drive gear 27 rolls on the rack 13 of the spiral groove 12, and the guide rod 14
It gradually rises while rotating in the direction of the upper orbit around the center of rotation. When the drive gear 27 rolls on the rack 13 to the top of the opening 12, the transfer table 20 is approximately
Rotated 180 degrees, and lower orbit 31 and upper orbit 3
It rises by 2 steps and reaches the position where it connects with the upper track 32.

When the transfer table 20 reaches the connecting position with the upper track 32, a locking hook 3 is attached to the front lower edge of the transfer table main body 21.
4 engages and locks the transfer platform 20 in that position. On the other hand, the spring 28 screwed onto the guide rod 13 at the upper part of the guide tube 23 is compressed between the guide tube 23 and the upper support of the guide rod 14, and acts to spring the guide tube 23 downward. When the transfer table 20 is connected and locked with the upper track 32 in this state, the rotation of the drive gear 27 is blocked, so that the transfer table main body 2
The gear 26 of No. 1 also stops rotating, and this gear 26 functions as a rack. Therefore, the traveling body 40 has a small gear 42 protruding from the driving rear wheel 41,
A strong forward force is applied by the meshing with the gear 26 and the rack 25, and it rides on the stopper 21a and moves to the upper track 32 while being pushed downward.

Bridge 3 where the traveling body 40 jumps up from the upper track 32
6, the bridge 36 is pushed down by the weight of the vehicle 40 to form a bridge running path.
At the same time, the link mechanism 37 operates due to the lowering of the bridge 36, pushes down the locking hook 34 against the tension spring 35, releases the engagement with the transfer table main body 21, and moves the upper track 32 of the transfer table 20 to the connected position. Release the lock.
Transfer platform 20 released from locking by locking hook 34
is the spring 28 compressed at the top of the guide tube 23.
The gear 27 rolls on the rack 13 along the spiral groove 12 due to the elastic force and weight of the lower track 31.
It descends to the position where it connects with and returns to the initial state. When the transfer table 20 returns to its initial state and the traveling body 40 runs away from the bridge traveling path, the bridge 36 jumps up again.
The locking hook 34 is also returned to its upwardly biased state by the tension spring 35.

As described above, according to the present invention, it is possible to smoothly rotate and transfer the traveling body between the lower track and the upper track, which are separated by a predetermined step, and it is possible to change the means of movement of the traveling body, and to make it possible for the traveling body to move smoothly. To make playing with toys even more fun. Furthermore, since the traveling body travels on the upper track and the transfer table is automatically returned to its initial state by operating the release member, it is possible to perform not only the transport operation of the traveling body but also the return operation of the transfer table. This can be enjoyed as a series of related operations, and the traveling body can be reliably transferred from the transfer table to the upper track. Furthermore, since the rotating and rising movement of the transfer table is performed using the driving force of the traveling body without providing a driving source such as a battery, it gives a mysterious feeling to young children and attracts more interest. can.
