[Technical field to which the invention belongs]

 The present invention relates to a runway switching device for driving a self-propelled traveling toy, and more particularly to a runway switching device having a function of changing a traveling destination on a three-way intersection.

[0002]

[Prior art]

 Conventionally, a traveling path for a self-propelled traveling toy has only been traveling on a predetermined traveling path, and has only been able to perform simple traveling. In particular, the layout of the course was limited because it was not possible to pass through a T-shaped three-way junction. Therefore, as shown in FIG. 5, three guide levers 31 and 3233 are rotatably arranged on a runway near the center of the three-way 30 and two guide levers (for example, 31 and 32) are attached with arrows. A lane switching device that forms a lane by rotating as described above has been proposed.

[Embodiment of the invention]

 FIGS. 1 and 2 show a track switching device according to the present invention. The switching device is composed of a three-forked road 1 where three roads join and a slide member 2. The three-way junction 1 is formed in a substantially triangular shape, and runways 3, 4, and 5 are formed at portions corresponding to the vertices, respectively, so that traveling toys do not jump out at portions corresponding to the three sides. Guide walls 6, 7, and 8 are formed, and other runways 10, 11, and 12 are formed to be connected to the respective runways 3, 4, and 5.

In the three-forked road 1, a guide wall 6 formed at a portion corresponding to a side formed by the first runway 3 and the second runway 4 is formed linearly, and the first runway 3 and the third runway 3 are formed. The guide walls 7 and 8 formed on the side corresponding to the side formed by the first runway 5 and the side formed by the second runway 4 and the third runway 5 are curved inwardly in an arc shape. It is formed. At the end of the three-way 1, a connecting mechanism 9 for connecting to another runway is formed. The coupling mechanism 9 includes a locking protrusion 9a and a locking receiving portion 9b, and engages with a locking receiving portion provided at an end of a running path to which the locking protrusion 9a connects. By engaging a locking projection provided at the end of the runway with the portion 9b, the fork is connected to another runway.

A slide member 2 is slidably disposed inside the three-way junction 1. The sliding member 2 is a box-shaped member having a substantially triangular shape and formed with side walls 16, 17, and 18 having substantially the same height as the guide wall, and two adjacent side walls 16, 17 are formed in an arc shape inward. The other side wall 18 is formed in a straight line so as to be parallel to the guide wall 6. The side walls 16 and 17 are formed in a concentric shape having a diameter larger than the guide walls 7 and 8 of the above-mentioned three-forked road 1, and as shown in FIG. The width of the runway formed by the guide wall 7 and the side wall 16 is almost the same as the width of the runways 3 and 5, and furthermore, forms a runway curved in an arc shape. Furthermore, it is formed so that it can pass through another runway 12 smoothly.

When the slide member 2 is moved so as to close the first runway 3, as shown in FIG. 3B, the guide wall 8 and the side wall 17 are separated by the width of the runways 4 and 5. When a curved runway having substantially the same width is formed and the slide member 2 is moved so as to close the third runway 5, as shown in FIG. 3 (c), the guide wall 6 and the side wall 18 A straight path having almost the same width as the width of the running paths 3 and 4 is formed.

A T-shaped guide slot 20 is formed on the road surface of the three-way junction 1. The width of the guide slot 20 is formed to be slightly larger than the diameter of the engagement shaft 21 projecting downward from the lower surface of the slide member 1, so that the engagement shaft 21 can move inside the guide slot 20 smoothly, and When the engagement shaft 21 is moved to the end of the guide slot 20, the slide member 2 automatically closes one runway, and a runway connecting the other two runways is formed.

The engagement shaft 21 is a shaft having a knob 23 formed at the upper end thereof, is inserted into a through hole penetrating from the upper surface to the lower surface of the slide member 2, and furthermore, passes through the guide slot 20 and the three-forked road 1. A screw 25 with a washer is screwed into the protruding tip 21 a so that the slide member 2 does not separate from the three-way junction 1.

Further, a locking portion for locking the engagement shaft 21 is formed near the end of the guide slot 20. The locking portion is composed of a pair of locking protrusions 22, 22, and the distance between the tips of the locking protrusions 22, 22 is formed to be slightly smaller than the diameter of the engagement shaft 21. When the engaging shaft 21 is moved to the terminal end of the slot 20, the engaging shaft 21 is locked by the locking projections 22 and 22 and its position does not change unless an external force is applied, and the traveling toy runs. It is possible to prevent a trouble such that the position of the slide member is displaced and the traveling toy cannot pass through the three-way junction.

As shown in FIG. 4, a shaft 26 a is provided rotatably with respect to the slide member 2, and a bulging portion 26 b is formed at a lower end protruding downward from the guide slot 20. An outer screw 26c is formed at the tip that protrudes upward through the slide member 2, and a knob 27 formed with an inner screw is screwed into the outer screw 26c, and the knob 27 is screwed into the shaft 26a. As shown in FIG. 4B, the slide member 2 may be pressed against the road surface of the three-way junction 1 so that the slide member 2 does not move unless a conscious operation to loosen the knob is performed.
