Description

[Detailed description of the invention] This invention relates to a traveling car toy that runs by the telescopic opening and closing operation of a pantograph-type telescopic opening/closing arm that extends long in front of the toy body. The object of the present invention is to provide a highly interesting traveling car toy in which the toy body intermittently moves forward by the action of casters while opening and closing.

The structure of a toy running vehicle according to an embodiment of this invention will be described below in detail with reference to the drawings. In the figure, 1 is a toy shaped like a frog, and non-driven running wheels 2 are pivoted on both sides of its body. ing. 3 and 4 are shafts 3 attached to the front part of the toy body 1 so as to rotate around a vertical axis.
A pair of left and right meshing gears attached at a and 4a are rotated in the direction of the arrow in FIG. 1 by a drive device 5 mounted on the toy body 1. The drive device 5 is a battery 6
It consists of a small motor 7 operated by a motor, a pinion 8 attached to the motor shaft, and an interlocking gear 9 that transmits the rotation of the pinion to one gear shaft 4a. Reference numeral 10 denotes a pantograph-type telescopic opening/closing arm that extends long in front of the toy body 1, and includes two link members 12 on the base side having equal lengths and having nine pin holes 11 bored therein at equal intervals. , 13 and 8
It is composed of a total of four link members, two link members 15 and 16 on the distal end side having equal lengths and having pin holes 14 drilled at equal intervals. The two link members 12 and 13 on the base side are crossed in an X shape at an arbitrary pin hole position, for example, the second pin hole position from the end, and are connected by inserting an opening/closing fulcrum pin 17,
Further, the base end portions are pivotally mounted onto the gears 3 and 4 by inserting eccentric crank pins 18 and 19 therein. on the other hand,
One end of the two link members 15 and 16 on the distal side is connected to the distal end of the link members 12 and 13 on the proximal side by inserting the connecting pins 20 and 21 into the pin holes, but the other end of one link member 15 ( The tip pin hole) is press-fitted into the large-diameter boss portion 22a of the caster mount 22 and fixed, and the other end (tip pin hole) of the other link member 16 is fixed to the small-diameter boss portion 22a of the caster mount 22.
It is attached as shown in Fig. 2 by loosely inserting it into b. The caster mounting base 22 has a directional projection 22c that projects forward.
on the outer periphery of the lower end, and the caster 2 is placed under this protrusion.
A stopper 26 is provided for restricting the rotation range of 5. The above caster 25 is the telescopic opening/closing arm 1
The wheel 25a is mounted by a rotating shaft 23 passing through the center of the caster mount 22 and a shaft stop 24 so that the direction of the floor-contacting wheel 25a can be changed within an appropriate angular range with respect to the opening/closing axis of the caster mount 22. In addition, the rotation range of this caster 25 is the same as that of the caster fork base 2.
Both end surfaces of a notch 27 formed on the outer periphery of 8 are defined by colliding with the stopper 26.

When the meshing gears 3 and 4 are driven to rotate by the operation of the drive device 5, the telescopic opening/closing arm 10 performs the telescopic opening/closing operation by the crank movement caused by the rotation of the gears. In this case, the caster 25 rotates so that the floor contact wheel 25a faces straight with respect to the opening/closing axis when the opening/closing arm 10 extends, and the floor contact wheel 25a rotates when the opening/closing arm 10 contracts in the direction of arrow A in FIG. 25a rotates so as to be inclined with respect to the opening/closing axis as shown in FIG. Therefore, when the opening/closing arm 10 is extended, the toy object 1 does not run, but when the opening/closing arm is retracted, the toy object 1 moves forward in the direction of arrow B in FIG. By repeating this process, the toy object 1 will move forward intermittently.

Since the toy vehicle of this invention has the above-mentioned structure, it is interesting that the pantograph type telescoping arm extends and closes in front of the toy body, and the toy body moves forward intermittently due to the action of the caster. This has the effect of increasing the interest of this type of toy.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) A toy body with non-driven running wheels, which is pivoted at the front of the toy body and driven to rotate about a vertical axis by a drive device mounted on the toy body. It consists of a pair of left and right meshing gears, and a pantograph-type telescopic opening/closing arm that extends long in front of the toy.The two link members on the base side are crossed in an X shape and connected by an opening/closing fulcrum pin. A telescopic opening/closing arm whose end portion is pivotally connected to the meshing gear with a crank pin, and a rotatable caster attached to the tip of the telescopic opening/closing arm so that the direction of the ground wheel can be changed with respect to the opening/closing axis. A running car toy comprising: (2) The above-mentioned pantograph type telescopic opening/closing arm consists of four link members with a plurality of pin holes drilled at equal intervals, and the two link members on the base side having the same length are inserted into the predetermined pin holes. At the same time, the tip of this base side link member and the ends of the two tip side link members having the same length are connected by inserting the connecting pin into the pin hole.
