The other end of the rotating lever 31 is connected to the loading platform 29.
One end of the rotary lever 31 facing downward and toward the loading platform 29 faces a position where it can engage with a stopper 34 protruding from the truck 28. Therefore, if the overall center of gravity of the loading platform 29 is set to the rear side of the pin 29a in FIG. is also rotated toward the front in FIG. 4 about the pin 29a. Then, when this pressing force is released, the loading platform 29 returns to its original state. A lumber model 35 is loaded in this loading platform 29. Reference numeral 36 denotes a return spring for the rotating lever 31, and the inner end of the rotating lever 31 is always pressed against the stopper 34 by the force of this spring.

On the other hand, the vehicle designated by reference numeral 4 is a motorized vehicle that runs while pulling the freight car 5 mentioned above. Inside the power vehicle 4,
As shown in FIG. 5, a motor 37 is attached, and a pinion gear 38 is attached to the tip of its output shaft.
is fixed. Two crown gears 39 and 40 are arranged to sandwich this pinion gear 38. 2 crown gears 39, 40
As shown in FIG. 6, the pinion gear 38 is fixed to a support shaft 41 arranged perpendicular to the axis of the pinion gear 38, and the support shaft 41 is provided so as to be movable in the axial direction. Of the two crown gears, one of the crown gears 40 has a relatively long pinion gear 42 protruding from the outer surface integrally therewith.

This positioning lever 53 is biased in the projecting direction by a spring 55 loaded between it and the device fixing part.
By bringing the shaft 51 into contact with the inclined surface 54, the switching state of the switching lever 47 can be maintained.

Next, the operation of this embodiment configured as above will be explained.

First, when the power car 4 pulling the freight car 5 approaches the station building 1 from the lower side of the elevated track 3 that has branched off, a protrusion at the tip of the rotating lever 31 provided on the lower side of the loading platform 29 of the freight car 5 appears. 33 is guided to the lower side of the high part 25b of the guide surface 25 of the station building 2, as shown by the chain line in FIG. 3B. As a result, the tip of the rotary lever 31 is pressed downward as it reaches the lower center of the guide surface 25, and the loading platform 29 is rotated counterclockwise in FIG. 4 about the pin 29a. Therefore, the left side of the loading platform 29 in the direction of movement is rotated so as to be lower, and the lumber model 35 in the loading platform 29 is moved to the lid 19 of the station building 1.
The products are rolled onto the slope 21 and loaded. Even if there are a plurality of freight cars 5, the lumber models 35 loaded on each freight car are similarly loaded on the slope 21. The timber model that has rolled down on the slope 21 faces into the lower opening of the frame 22 and is transferred into the semi-cylindrical rotary cylinder 17 with its open side facing upward.
These operations are performed without the power vehicle 4 stopping. When the power vehicle 41 passes the station building 1 and approaches the end of the branch track 2, the shaft 51 at the lower end of the switching lever 47 comes into contact with a sloped piece 52 for direction change protruding from the track, and the protruding piece of the switching lever 47 4
Stoppers 45, 4 of the support shaft 41 by 9, 50
6 is pressed, the support shaft 41 is moved in the axial direction, and the engagement between one of the crown gears 39, 40 and the pinion gear 38 is changed. As a result, the rotational direction of the support shaft 41 is reversed, and the power vehicle 4 begins to move backward. During this backward movement, when the rotary lever 31 provided on the loading platform 29 of the freight car 5 approaches the guide surface 25, the tip of the rotary lever 31 moves toward the guide surface, as shown by the solid line in FIG. 3B. rides on the upper side of the guide surface 25 from the lower part 25a of 25,
Therefore, the tip of the rotation lever 31 is pushed upward, and the loading platform 29 of the freight car 5 is not rotated toward the station building 1 side. As we continued to retreat, we moved to station building 1.
approach the lower side of the Then, the inclined piece 9b at the tip of the operating lever 9, which is protruding from the outer wall 8 of the station building 1, comes into contact with the rotary lever 31. but,
At this time, the rotating lever 31 is pushed counterclockwise in FIG. 4 and comes into contact with the stopper 34, so the rotating lever 31 cannot be rotated, and as shown by the chain line in FIG. escape through the underside of the
At this time, the loading platform 29 is tilted slightly, but this is not a problem since there is no cargo. In this state, the power vehicle 4 runs on the track to its terminal end while pushing the empty freight car 5.

Although not shown, an inclined piece 52 for changing the direction is provided near the end of the track with the direction of the inclined surface changed, and when the shaft 51 of the switching lever 47 comes into contact with the inclined surface. , the switching lever 47 is rotated in the opposite direction to that described above, and the power vehicle 4 begins to move forward on the track.

When approaching the station building 1, the rotating lever 3 of the freight car 5
1 comes into contact with the inclined piece 9b of the operating lever 9. Then, the rotating lever 31 is rotated clockwise in FIG. 4 and tries to get over the inclined piece 9b, and at the same time pushes the operating lever 9 until it comes into contact with the right end of the opening 8a as shown in FIG.

During this time, since the motor vehicle 4 is running, the operating lever 9 is forcibly rotated counterclockwise in FIG. 7. This rotation is transmitted to the rotating lever 13 via the boss 10 and the shaft 11, and the rotating lever 13 is rotated counterclockwise in FIG. 2 about the shaft 11. As a result, the link lever 14 is moved by the spring 1.
8, the rotating cylinder 17 is rotated counterclockwise in FIG. It falls onto the loading platform 29 of the freight car 5 that is passing through. After one freight car has passed, the operating lever 9 is activated by the tension of the spring 18.
When the link lever 12 returns, the rotary cylinder 17 returns to its original state, and the next lumber model 35 is transferred into the rotary cylinder 15, waiting for the next operation.

Thereafter, similar operations are repeated to load and unload the timber models between the freight cars and the station building.

As is clear from the above explanation, according to the present invention, one station building is installed between the low track and the elevated track, cargo can be loaded and unloaded on the elevated track side, and cargo can be loaded and unloaded on the low track side. Because it is designed to allow loading operations to be carried out, and the motive power vehicles are configured to move forward and backward, only one station building is required, resulting in a three-dimensional station building, and the movement of the motive power vehicles changes, moving forward, backward, and during cargo handling operations. It is possible to provide an excellent and interesting orbital toy with large movements that are rich in movement.
