Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a toy two-wheeled vehicle that runs while maintaining its balance based on the principle of a built-in fly oil top, so-called a gyro.

(Prior Art) Conventionally, a vehicle body is formed by combining a main body made of lightweight material, a front wheel support portion, and a cowl/hood, and a drive source that also serves as a balancer is placed at a low center of gravity inside the vehicle body, and A motorcycle toy consisting of a plurality of protrusions for promoting rising was developed in 1982.
This is publicly known from Publication No. 143493 and the like.

(Problem to be Solved by the Invention) However, in this structure, the line connecting the ground contact part of the front wheel, the tip of the protrusion for promoting lifting, the main body, the wheel support part, and the outer surface of the cowl/hood is the front side. When viewed from above, it has a vertically elongated egg shape, so when the toy rolls over while running, it is difficult to do so by making one full rotation in the horizontal direction and standing up. Not only is this not possible, but the lifting promotion protrusion is rod-shaped and protrudes laterally, so if the vehicle falls sideways on the flooring, such as a short-pile carpet, its tip will sink into it. There have been problems in that the rollers may pierce or pierce, making it impossible to fully demonstrate the function of promoting the vehicle's standing up.

(Means for Solving the Problems) The present invention has a battery box installed on the lower surface of the body between the driven front wheels and the driving rear wheels in a state slightly lifted from the floor surface, and A guide frame is installed on the outside of both the left and right sides of the body, and a windshield member is attached to the top surface of the body.As seen from the front, the guide frame is attached to the ground contact part of the driven front wheel, the battery box, and the guide frame on both sides of the upper half of the body. To provide a balanced running two-wheeled vehicle toy, characterized in that each of the outer surfaces of a frame and a windshield member continuously exhibits a perfect circular shape when viewed from the front, and is not provided with any other mechanism, member, etc. that protrudes to the outside. This is an attempt to solve these problems.

(Embodiment) A hollow body 1 is made of hard plastic, and a pair of left and right support walls 2, 2' are provided rearwardly at a rearward portion of the body 1, and a rear support wall 2, 2' is provided between the left and right support walls 2, 2'. A side axle 3 is rotatably passed over the rear axle 3, and a drive rear wheel 4 with a tire 4' and a drive gear 5 are fixed non-rotatably to the rear axle 3.
A horizontal rod 6 is provided in the front part of the horizontal rod 6 facing left and right, and a pair of T-shaped plates 7, 7' are arranged above and below the middle part of this horizontal rod 6, and the vertical of the T-shaped plates 7, 7' is arranged. The ends of the front forks are rotatably supported at the same location about a vertical axis, and the upper ends of a pair of left and right front forks 9, 9' are fixed to both ends of the horizontal parts of these T-shaped plates 7, 7'.
A driven front wheel 11 with a tire 11' is connected via a front axle 10 between the lower ends of both front forks 9 and 9'.
A battery box 12 is mounted on the lower side of the middle part of the body 1 so that the left and right weights are balanced and the lower surface is slightly lifted from the floor. A power on/off switch 16 is provided on the top surface of the lever 13 to connect and disconnect the movable contacts 14, 14' and the fixed contacts 15, 15' by swinging the lever 13.
The motor mounting plate 17 is fixed in the body 1 by a support 18 so that the motor mounting plate 17 is located on a plane parallel to the vertical plane including the front-rear line. A motor 20 is fixed to the center of the mounting plate 17 with its rotating shaft 21 facing left and right, with its left half protruding to the left side of the mounting plate 17, and its right half protruding to the right side. A peripheral wall portion 23 of the rotating member 22 surrounds half of the motor 20 and the rotating shaft 21
Further, a donut-shaped fly life oil 24 is fixed to the outer periphery of the peripheral wall portion 23 at a position where the fly life oil 24 rotates on the above-mentioned vertical plane, and the rotating shaft 2
The rotating member 22 is lined up at one end of the 1, a spur gear 26 is fixed to it, and the spur gear 26 and the drive gear 5 are connected by a large number of transmission gears 27, 28, 29, 30, and 31 to achieve balance. A running two-wheeled vehicle toy main body A is constructed, and furthermore, the rear end of the body 1 bears an auxiliary idler wheel 33 that lands when the toy main body A stands up and runs with only the driving rear wheel 4 landing, and also supports the lower surface of the battery box 12. is the bottom-shaped part 34 that lands when the toy main body A is tilted to the left or right, and there are parts near the front end and near the rear end of both left and right sides of the upper half of the body 1 when the toy main body A falls sideways. A pair of left and right guide frames 35, 35',
36, 36' are attached, and a streamlined windshield member 37 is fixed to the front half of the upper surface of the body 1, and the same surface is fixed to the horseback-shaped portion 3 on which the toy body A will land when it is turned over.
8, and when viewed from the front as a whole, the ground contact part of the driven front wheel 11 and the battery box 1
2. Guide frames 3 on both sides of the upper half of body 1
5, 35', 36, 36' and the outer surfaces of the windshield member 37 have a continuous perfect circular shape when viewed from the front, and there are no other mechanisms, members, etc. that protrude to the outside.

In addition, in the figure, 40 is the lid of the battery box 12;
Reference numeral 1 indicates a hinge portion of the lid portion 40, 42 a locking device of the lid portion 40, and 43 the protrusion height of the front forks 9, 9'.

That is, in the above description, when the toy two-wheeled vehicle is run, first operate the power on/off switch 16 to turn the motor 20 into a rotating state, and then the rotating shaft 21, rotating member 22, and fly oil of the motor 20 are turned on. 24, spur gear 26, transmission gears 27 to 3
1. Rotate the drive gear 5, drive wheels 4, and rear axle 3, then place the entire unit in an upright position on the running floor in the rotated state, release your hands, and let it run in equilibrium. However, even if the main body of the toy two-wheeled vehicle were to fall sideways due to an external force during the balanced running and then rotate once, the aforementioned horse back shaped portion 38, one side guide frame 35, 36 or 35', 36 ' and one side of the bottom shaped part 34 guide the whole to make one rotation in the lateral direction, and the weight of the battery box 12 containing the batteries returns the whole to an equilibrium running state to enable normal movement, In other words, even if the toy two-wheeled vehicle falls sideways and rotates once due to an obstacle on the road, it immediately rightes itself and continues traveling.

(Operations and Effects of the Invention) The present invention is equipped with a battery box slightly lifted from the floor surface at a location between the driven front wheel and the driving rear wheel on the lower surface of the body. A guide frame is installed on the outside of both the left and right sides of the half part, and a windshield member is attached to the top surface of the body, and when viewed from the front, the ground contact part of the driven front wheel, the battery box, and the upper half of the body are installed. The guide frames on both sides and the outer surfaces of the windshield members have a continuous perfect circular shape when viewed from the front.
It is characterized by the fact that it does not have any other mechanisms or members that protrude to the outside, so even if it falls sideways due to an external force during balanced running, it immediately rotates 360 degrees and returns to its previous state, continuing to maintain balanced running. Compared to the above-mentioned known motorcycle toy, which has a vertically elongated egg-shaped front surface and cannot necessarily rotate horizontally smoothly, the same operation can be performed easily and reliably. In addition, the guide frames provided on both sides of the body extend from the same plane and are formed along the vertical direction, so that even if the toy body falls sideways while running on a carpet, the toy remains in a rod shape. Unlike the rising protrusion on the toy main body, there is no risk that this protrusion will sink into or pierce the carpet surface, thereby reliably guiding the rotational standing up.
The present invention has the effect of being able to sufficiently solve the above-mentioned problems.
