[Problems to be solved by the invention]
However, the above configuration is not a problem as long as the traveling toy has a short overall length, but, for example, in the case of a traveling toy such as a train or a bus having a rectangular bottom surface, when turning a curve, Although the portion where the guide shaft is located does not come off the traveling rail, the portion away from the guide shaft is separated from the traveling rail, so that there is a problem that traveling becomes unnatural especially with a traveling toy such as a train.
[0005]
In addition, when the width of the wheel is reduced for miniaturization, there is a problem that the wheel gets stuck on the traveling rail during traveling.
[0006]
An object of the present invention is to provide a traveling toy which solves the above-mentioned problems and which can travel naturally even when the traveling toy is long, and which can realize the miniaturization of the toy body.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, a traveling toy according to the present invention is a traveling toy that travels on an endless traveling rail configured by abutting a plurality of panels having guide grooves so that the guide grooves are continuous. And the following requirements.
(A) A rear wheel driven by a motor or a mainspring as a power source and a freely rotating front wheel are provided. (B) The center of the bottom of the toy body is centered on a rotating shaft provided on the center line. A guide wheel rotatably supported by a rotatable holder and a guide pin provided on the center line are arranged back and forth (c) The guide wheel and the guide pin can be engaged with the traveling rail. (D) The guide wheel and the guide pin are formed to have a width smaller than that of the traveling rail.
It is preferable that the guide wheels contact the groove bottoms of the traveling rail when placed on the traveling surfaces on both sides of the traveling rail, and the front wheels are slightly lifted off the traveling surface.
[0009]
[Embodiment of the invention]
In FIG. 1, reference numeral 1 denotes a traveling toy. The traveling toy 1 travels on an endless traveling rail 3 formed by abutting a plurality of panels 2 having guide grooves so that the guide grooves are continuous.
[0010]
The traveling toy 1 has a form imitating a train, and includes a pair of rear wheels 4 provided at a rear portion and a pair of front wheels 5 provided at a front portion and rotating freely as shown in FIG. . A drive mechanism (not shown) using a motor as a power source is provided in the toy body 1a, and this drive mechanism is connected to the rear wheel 4. A switch 6 is provided in a circuit connecting the motor and the battery. A conventional drive mechanism may be used. The traveling toy may be driven by a mainspring.
[0011]
Next, as shown in FIG. 3, a guide wheel 7 and a guide pin 8 are arranged on the center line P at the bottom of the toy body 1a.
[0012]
The guide wheel 7 is arranged inside a circular concave portion 9 provided at a position in front of the bottom of the traveling toy 1. A holder 10 is rotatably mounted inside the circular recess. The rotation axis of the holder 10 is provided on the center line P. The lower part of the rotating shaft is forked, and a guide wheel 7 is rotatably mounted inside the forked part. For this reason, the guide wheel 7 can be oriented in any direction of the front, rear, left and right of the traveling toy, and can be rotated following the traveling toy 1 in any direction.
[0013]
The guide pins 8 are arranged between the rear wheels 4.
[0014]
The guide wheel 7 and the guide pin 8 are formed so as to be able to engage with the travel rail 3 and have a smaller width than the travel rail 3.
[0015]
In addition, both the guide wheel 7 and the guide pin 8 are provided so as to protrude below the lower ends of the rear wheel 4 and the freely rotating front wheel 5. When the guide wheel 7 is placed on the running surface formed by the surfaces of the plurality of panels, the guide wheel 7 comes into contact with the groove bottom of the running rail 3, and at that time, the front wheel 5 is slightly lifted off the running surface. preferable. The guide pin 8 is formed to a length that does not contact the groove bottom of the running rail 3 when placed on the running surface formed by the surface of the panel 2.
[0016]
In the above configuration, when the switch 6 is turned on after the guide wheel 7 and the guide pin 8 of the traveling toy 1 are engaged with the inside of the traveling rail 3, the motor operates and the rear wheel 4 becomes a driving wheel and rotates. Therefore, the traveling toy 1 travels. The traveling toy 1 travels on three wheels, a pair of rear wheels 4 and a guide wheel 7. Since the guide wheel 7 is oriented in any of the front, rear, left, and right directions, the guide wheel 7 also rotates along the curve in a portion where the traveling rail 3 is curved as shown in FIG. At this time, if the front wheel 5 is in contact with the running surface, the vehicle is laterally displaced when making a curve, so that the resistance to running is increased. However, the running is smooth because the vehicle is floating from the running surface.
[0017]
In addition, when the traveling toy 1 travels on a sharp curve at a high speed, the traveling toy 1 is shaken to the outside of the beave due to centrifugal force. Since the front wheel 5 lands on the running surface, the running toy 1 does not tilt any more, and can run stably as a whole.
[0018]
When the front wheel 5 travels on a curve, the rear wheel 4 follows the travel rail 3 and moves closer to the inside of the curve, so that the rear wheel 4 travels in an unnatural state in which the rear wheel 4 comes off the travel rail 3. Further, at a portion where the curve is tighter, one of the rear wheels 4 may fall into the traveling rail 3. However, since the guide pins 8 are provided between the rear wheels 4 and the guide pins 8 are engaged with the traveling rails 3, the left and right rear wheels 4 are always held on both sides of the traveling rails 3. Therefore, the traveling of the rear part of the traveling toy 1 is natural, and the rear wheel 4 does not fall into the traveling rail 3. Therefore, the width of the rear wheel can be reduced (not to mention the front wheel), so that downsizing can be realized.
[0019]
Further, since the guide wheel 7 and the guide pin 8 are formed to have a width smaller than that of the travel rail 3, the contact friction between the guide wheel 7 or the guide pin 8 and the travel rail 3 is also small. Therefore, there is no obstacle to running.
[0020]
In the above-described example, the guide wheels 7 are provided between the front wheels 5 and the guide pins 8 are provided between the rear wheels 4. On the contrary, the guide pins 8 are provided between the front wheels 5 and the rear wheels are provided. 4 may be provided with a guide wheel 7.
[0021]
[Effect of the invention]
According to the first aspect of the present invention, since the guide wheel 7 is oriented in any of the front, rear, left, and right directions, the guide wheel also rotates along the curve at a portion where the traveling rail is curved. When the front wheel runs on a curve, the rear wheel follows it and moves closer to the inside of the curve than the running rail, so it will run in an unnatural state where the rear wheel deviates from the running rail, and in places where the curve is tighter One of the rear wheels may fall into the running rail. However, since the guide pins are provided between the rear wheels and the guide pins are engaged with the traveling rail, the left and right rear wheels 4 are always held on both sides of the traveling rail. Therefore, the traveling of the rear part of the traveling toy is natural, and the rear wheels do not fall into the traveling rail, so that traveling can be performed smoothly even without the traveling toy. Therefore, the width of the rear wheel can be reduced (not to mention the front wheel), and downsizing can be realized.
[0022]
Further, since the guide wheels and the guide pins are formed to have a width smaller than that of the travel rail 3, the contact friction between the guide wheels or the guide pins and the travel rail 3 is also small. Therefore, there is no obstacle to running.
[0023]
According to the invention of claim 2, the guide wheel also rotates along the curve at a portion where the traveling rail is curved. At this time, when the front wheel is in contact with the running surface, the vehicle is laterally displaced when making a curve, thereby increasing resistance to running. However, the running is smooth because the vehicle is floating from the running surface.
