Description

  The present invention relates to a direction-changing traveling toy provided with a direction-changing device that automatically changes the traveling direction in the reverse direction when it collides with an obstacle on a course.

  Conventionally, as disclosed in Patent Document 1, the direction change traveling toy is rotatably supported by a knuckle arm that is supported by a vehicle body so as to be pivotable to the left and right, and the knuckle arms of the left and right steering wheels are tie rods. In other words, the tie rod is operated by a rotating cam and the direction of the steered wheels is changed by swinging left and right.

  In Patent Document 2, it is arranged on the left and right sides of the vehicle body, is pivotally supported in a stationary state without changing the direction of the driving wheel, rotates the driving wheel in the same direction, and moves forward and rotates the driving wheel in the opposite direction. Then, a direction change traveling toy that changes direction is proposed.

  In Patent Document 3, when the table surface is set as the traveling surface, the front wheel is removed at the edge, and the third driving wheel that is pivotally supported in a direction orthogonal to the front wheel is in contact with the traveling surface to change direction and travel again. Returning to the surface, and when a collision with an obstacle ahead, the third driving wheel that was above the front wheel moves below the front wheel to contact the traveling surface and changes direction, suggesting a direction-changing traveling toy Has been.

  Although not searched in recent patent documents, a switching gear of a transmission mechanism in which a traveling toy body is provided with an operating rod having a tip projecting forward and backward in the traveling direction, and is disposed on the traveling toy body and rotates a driving wheel. The direction-changing traveling toy that links the middle of the operating rod to the other, moves the operating rod in the opposite direction by the collision of the traveling toy, rotates the switching gear, changes the rotation direction of the transmission mechanism, and changes the traveling direction. Are known.
