【００１０】
【実施例】
以下、この発明の走行玩具の落下防止方向転換装置を図面に示す実施例により説明すると、この実施例の走行玩具の落下防止方向転換装置１において、従来と同様に、玩具車体２の前部２ａにおいて、方向転換半径３の外側と内側に遊転前車輪４、４を配備し、同後部２ｂにおいて、方向転換半径３の外側と内側に駆動後車輪５、駆動後車輪６を配備し、前記遊転前車輪４、４と駆動後車輪５、駆動後車輪６の中間であって、かつ遊転前車輪４、４よりに、方向転換輪７を配備している。そして、駆動後車輪５の前方に中間駆動後車輪８を、駆動後車輪６の前方に中間遊転後車輪９をそれぞれ同一軸線上に配備してなるものである。中間駆動後車輪８は、駆動後車輪５と中継伝動輪１０を介在して駆動している。図示しないが、中継伝動輪１０の代りに歯車、ベルト等の伝動機構によってもよいものである。

図面において、１１はモーター、１２はモーター軸、１３はモーター軸１２の一端１２ａに固着したウオームギヤ、モーター軸１２の他端１２ｂは、方向転換輪７の周面に連接して回転を伝動している。１４はウオームギヤ１３と噛合するギヤで後車軸１５に固着され、両端に駆動後車輪５、駆動後車輪６を固着している。駆動後車輪６を遊転後車輪としたときは、固着しない。１６は電池ボックスで、内方に電池１７を収容している。
【００１２】
この実施例の走行玩具の落下防止方向転換装置１は、前述のように構成され、従来の駆動後車輪５の前方に中間駆動後車輪８を配備しているから、方向転換輪遊転前車輪４、４７との距離が短くなり、その方向転換半径を小さくして小回りをなし、かつ、中間駆動後車輪８が走行玩具の重心に近接するから、遊転前車輪４、４の両方又は一方が走路面より落下すると、中間駆動後車輪８に走行玩具の重力を受け、安定して方向変換を行うものであり、従来の方向転換輪７と長く離れた駆動後車輪５で行う方向変換駆動力に比較して強力な方向変換駆動力が作用して走行玩具を走路面に確実に戻し、走路面の側縁から落ちなくするものである。なお、方向転換半径３の内側に配備する駆動後車輪６は、遊転後車輪とすることができる。
【００１３】
【発明の効果】
この発明の走行玩具の落下防止方向転換装置は、以上のようになるから、方向転換輪と中間駆動後車輪との距離が短くなり、その方向転換半径が小さくなり、中間駆動後車輪は走行玩具の重心に近接するから、遊転前車輪４、４の両方又は一方が走路面より落下すると、その走行玩具の重心に近い重力を受け、安定して小回りをなして車体前端の前車輪落下地点から車体を走路面に確実に戻し、走路面の側縁から落ちなくするものである。
【００１４】
よって、この発明の走行玩具の落下防止方向転換装置は、ゼンマイ原動機によるミニ走行玩具から電動走行玩具まで広く活用できるものである。

[0009]
DETAILED DESCRIPTION OF THE INVENTION
At the front part of the toy car body, wheels before rotation are arranged outside and inside the direction change radius, and after driving wheels are arranged outside the direction change radius and wheels after rotation are arranged inside the direction change radius. In the fall prevention direction changing device for a traveling toy, in which a direction changing wheel is arranged in a right-angled transverse direction between the pre-swing wheel and the post-drive wheel and near the pre-swing wheel, The wheel after the intermediate drive is arranged on the same axis in front of the wheel after the intermediate drive and the wheel after the intermediate drive in front of the wheel after the drive inside the direction changing radius, and the wheel after the intermediate drive is relayed with the wheel after the drive. A traveling toy fall prevention direction changing device that is driven through a transmission wheel.
[0010]
【Example】
Hereinafter, a traveling toy fall prevention direction changing device of the present invention will be described with reference to an embodiment shown in the drawings. In the traveling toy fall prevention direction changing device 1 according to this embodiment, a front portion 2a of a toy vehicle body 2 is conventionally provided. In the rear portion 2b, the driven wheels 5 and the driven wheels 6 are disposed on the outer and inner sides of the direction changing radius 3, respectively. A direction change wheel 7 is provided between the pre-rotation wheels 4 and 4 and the post-drive wheels 5 and the post-drive wheels 6 and more than the pre-rotation wheels 4 and 4. Further, the intermediate post-drive wheel 8 is disposed in front of the post-drive wheel 5 and the intermediate idle wheel 9 is disposed in front of the post-drive wheel 6 on the same axis. The intermediate drive post-wheel 8 is driven via the post-drive wheel 5 and the relay transmission wheel 10. Although not shown, a transmission mechanism such as a gear or a belt may be used instead of the relay transmission wheel 10.
[0011]
In the drawing, 11 is a motor, 12 is a motor shaft, 13 is a worm gear fixed to one end 12a of the motor shaft 12, and the other end 12b of the motor shaft 12 is connected to the peripheral surface of the direction change wheel 7 to transmit rotation. Yes. A gear 14 meshes with the worm gear 13 and is fixed to the rear axle 15, and the driven wheel 5 and the driven wheel 6 are fixed to both ends. When the wheel 6 after driving is used as a wheel after idle, it does not adhere. Reference numeral 16 denotes a battery box, which houses a battery 17 inside.
[0012]
The traveling toy fall prevention direction changing device 1 of this embodiment is configured as described above, and the intermediate post-drive wheel 8 is arranged in front of the conventional post-drive wheel 5, so that the wheel before turning around the direction change wheel. Since the distance to 4, 47 is shortened, the turning radius is reduced to make a small turn, and the wheel 8 after intermediate driving is close to the center of gravity of the traveling toy, both or one of the pre-rotation wheels 4, 4 When the vehicle falls from the road surface, it receives the gravity of the traveling toy on the wheel 8 after the intermediate drive and stably changes the direction, and the direction change drive is performed on the post-drive wheel 5 that is far away from the conventional direction change wheel 7. Compared to the force, a strong direction change driving force acts to reliably return the traveling toy to the running road surface and prevent it from falling off the side edge of the running road surface. In addition, the post-drive wheel 6 provided inside the turning radius 3 can be a post-rotation wheel.
[0013]
【The invention's effect】
The traveling toy fall prevention direction changing device of the present invention is as described above. Therefore, the distance between the direction changing wheel and the wheel after intermediate driving becomes shorter, the direction changing radius becomes smaller, and the wheel after intermediate driving becomes the driving toy. When both or one of the pre-rolling wheels 4, 4 falls from the running road surface, it receives gravity close to the running toy's center of gravity and makes a small turn in a stable manner. The vehicle body is surely returned to the running road surface, so that it does not fall from the side edge of the running road surface.
[0014]
Thus, the traveling toy fall prevention direction changing device of the present invention can be widely used from a mini-running toy powered by a mainspring motor to an electric running toy.
