Hereinafter, one embodiment of the present invention will be described based on the drawings.

Figure 1 is an overall perspective view of a track joint for a traveling toy;
Figure 2 is a sectional view of the main body when the traveling body is transferred to the turntable, Figure 3 is a sectional view of the main body when the traveling body falls from the turntable to the traveling body cradle, and Figure 4 is a sectional view of the main body when the traveling body is transferred to the turntable.
The figure shows a top perspective view of the turntable.

In the drawings, reference numeral 10 denotes a main body of the continuous body, which is disposed between an upper track 31 and a lower track 32 that are separated by a predetermined step. The main body 10 includes a slope 11 that slopes from the top to the bottom, and a slope 1.
1, and a reversing table 12 having a predetermined width and having a gentle slope in the opposite direction to the inclined table, and a traveling body holder 13 having a substantially U-shaped cross section and continuing below the reversing table 12. It is integrally and continuously formed. Above the inclined table 11, an upper track 3 is provided.
An entrance track 14 connected to 1 is provided horizontally,
Further, a turntable 20 adjacent to this entrance track 14 is provided in a recess 16 on the ramp 11.
Further, the traveling object cradle 13 is connected to the lower track 32, and a cushioning material 15 made of rubber or the like is adhered to the upper surface of the cradle 13.

The turntable 20 has an entrance track 14 on the entrance side.
It has a circular shape with a protruding connecting track 21,
A traveling guide wall 22 is provided on one side of the upper surface, a rack 23 is provided in the front on the other side, a gear 24 is provided partially protruding backward, and a stopper 20 is provided in the center of the front part.
A is provided. In addition, at the center of the lower surface of the turntable 20, there is a tilting base 1 with respect to the turntable plane.
The bearing part 25 is inclined at an angle that is a supplementary angle to the inclination angle of 1, that is, the sum of the inclination angle of the inclination table 11 and this angle is a right angle. An upright shaft 26 is pivotally mounted. Therefore, when the turntable 20 is connected to the entrance track 14, the angle of inclination of the ramp 11 and the angle of inclination of the bearing portion 25 cancel each other out, and the turntable 20 is in a horizontal state. On the other hand, when the turntable 20 rotates approximately 180 degrees as described later,
The turntable 20 is tilted at an angle twice the tilt angle of the tilt table 11.

A drive gear 27 is pivotally attached to the lower part of the turntable and communicates with the gear 24 via an intermediate gear 24a.The drive gear 27 meshes with a semicircular ring gear 17 formed on the upper surface of the recess 16 of the tilt table 11, and controls the rotation of the gear 24. The turntable 20 is rotated by 180 degrees by rolling on the ring gear 17. Reference numeral 28 denotes a tension spring stretched between the lower surface of the turntable 20 and the upper surface of the inclined table 11, which biases the turntable 20 so that it is always connected to the entrance track 14. Reference numeral 29 denotes a support rod provided at one peripheral end of the turntable 20, which is urged outward by a spring (not shown) and slides into contact with the peripheral side surface of the recess 16 of the inclined table 11. This support rod 29 is the turntable 20
In addition to helping maintain the posture of the
It comes into contact with a stopper 18 provided 180 degrees oppositely, and prevents the turntable 20 from rotating more than 180 degrees.

Reference numeral 40 denotes a running body in the shape of a car, which is self-propelled and 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 24 and transmit rotation when the traveling body 40 is transferred to the turntable 20. Further, reference numeral 43 denotes a wheel provided approximately at the center of the upper part of the traveling body 40 to allow the traveling body 40 to roll over smoothly. Note that the shape of the traveling body 40 can also 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 turntable 20 is connected to the entrance track 14 via the connecting track 21 and is in a horizontal state, when the traveling body 40 is transferred to the turntable 20 from the upper track 31, the traveling body 40 is moved to the stopper 20a. Therefore, progress is blocked. At this time, the small gear 42 protruding from the rear drive wheel 41 of the traveling body 40 meshes with the gear 24 partially protruding from the rear of the turntable 20, and rotates the gear 24 while causing the rear wheel 41 to slip. . This gear 24
The rotation is caused by the drive gear 27 via the intermediate gear 24a.
transmitted to. As a result, the drive gear 27 rolls on the semicircular ring gear 17 of the inclined table 11, and rotates the turntable 20 counterclockwise about the bearing 25 while resisting the tensile force of the tension spring 28. The turntable 20 has a bearing section 25
As mentioned above, since it is tilted at an angle that is a supplementary angle to the inclination angle of the tilt table 11, it will be tilted as it rotates counterclockwise, and when it has rotated approximately 180 degrees, it will not match the tilt direction of the tilt table 11. The table is tilted in the same direction at an angle twice the tilt angle of the tilt table 11. Therefore, the traveling body 40 on the turntable 20 rolls down from the turntable 20 toward the bottom of the inclined table 11 with its traveling direction changed by 180 degrees.
It rolls over on the inclined table 11 and reaches the reversing table 12, is further reversed by the reversing table 12, and falls in a normal posture onto the running body cradle 13, which has a substantially U-shaped cross section and continues below. The rolling motion at this time is particularly performed by the wheels 43, and the traveling body 40 falls smoothly and reliably onto the traveling body cradle 13. Further, the impact when the traveling body 40 falls onto the traveling body cradle 13 is alleviated by the action of the cushioning material 15.

The traveling body 40 that has fallen onto the traveling body cradle 13 in a normal posture starts traveling again and advances to the lower track 32. On the other hand, the turntable 20
0 rolls down and when the gear 24 and small gear 42 are disengaged, rotational force is no longer transmitted to the drive gear 27, so the counterclockwise rotation stops.
This time, on the contrary, the support rod 29 is rotated approximately 180 degrees clockwise by the tensile force of the tension spring 28 until it comes into contact with the stopper 18, and returns to the initial state.

Note that the rotation angle of the turntable 20 is determined by the intersection angle of the upper track 31 and the lower track 32, and in the case of the above embodiment, the upper track 31 and the lower track 32 intersect at an angle of 180 degrees. Therefore, the rotation angle of the turntable 20 is approximately 180 degrees. Therefore, the rotation angle of the turntable 20 is not limited to 180 degrees.

Furthermore, in the illustrated example, the turntable 20 is rotated by using the driving force of the running body 40 without providing a separate drive device such as a motor, so that the structure can be simplified, and it is possible to etc. can give a mysterious feeling and attract more interest.

As described above, according to the present invention, a turntable that rotates diagonally downward in half along a slope is disposed between an upper track and a lower track that are separated by a predetermined step. At the same time as the body changes direction, the traveling body rolls over on the inclined platform until it reaches the traveling body cradle and travels again on the lower track. Therefore, the traveling means of the traveling body can be made unexpected, and play with the traveling toy can be made more interesting and enjoyable.
