Description

[Detailed description of the invention] (Field of industrial application) The present invention is a four-wheel drive traveling toy configured to transmit the driving force of a drive unit for driving one of the front and rear wheels to the other wheel. Regarding.

(Prior Art) In general, four-wheel-drive traveling toys configured with a power source such as a spring are superior to two-wheel-drive toys in terms of power, hill-climbing power, etc., and can provide more interesting driving. However, because the mechanism is complicated, it is prone to failure and is expensive.

(Problems to be Solved by the Invention) The present invention has been made in view of the above-mentioned points of view, and is particularly capable of easily and reliably driving four wheels with a simple structure, and The aim is to propose a four-wheel drive toy with excellent running speed, power, hill climbing ability, etc.

(Technical means for solving the problem) As a technical means for solving the above problem, the four-wheel drive traveling toy according to the present invention includes:
The vehicle is characterized by being configured to be able to run by transmitting the driving force of a drive unit equipped with a drive mechanism to the wheels, and having the following requirements.

(a) The support shaft of the intermediate gear of the drive unit that transmits the driving force to either the front or rear wheels is provided so as to protrude outside of this drive unit.

(b) A crown gear is fixed to the support shaft of the intermediate gear, and a pinion that meshes with the crown gear is provided on the toy body.

(c) A crown gear that meshes with the pinion is fixed to the inside of the other wheel.

(Operations and Effects of the Invention) As configured above, according to the four-wheel drive traveling toy according to the present invention, the driving force of the drive unit that drives either the front or rear wheels is transmitted from the crown fixed to the support shaft of the intermediate gear. Since the crown gear meshes with the pinion from the gear via the pinion and is fixed inside the other wheel, the driving force of the drive unit is also transmitted to the other wheel. With this, the driving force is transmitted to the four wheels, so the running speed, power, and hill climbing ability are significantly increased, making it possible to obtain a running toy with an excellent sense of force and expanding the range of play. can.

(Example) Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

In the figure, symbol A indicates a four-wheel drive traveling toy according to the present invention. This four-wheel drive traveling toy A has a toy body 1 formed in the shape of a passenger car. and,
A drive unit a is attached to the inside of the toy main body 1, and the toy body 1 is configured to be able to travel by transmitting the driving force of the drive unit a to four wheels.

The drive mechanism of the drive unit a has the same structure as a conventional two-wheel drive drive mechanism, and includes a spur gear 3 fixed approximately at the center of the support shaft 2, and a mainspring 4 and pinion arranged in parallel on the left and right sides of the spur gear 3. 5 forms the main gear part S. Further, the spur gear 3 of the main gear portion S is meshed with a pinion 8 arranged in parallel with a spur gear 7 fixed approximately at the center of a support shaft 6 whose one end 6a protrudes from the side surface of the drive unit a. At the same time, the spur gear 7 is connected to the spur gear 1 fixed to the support shaft 9.
0 and is meshed with a pinion 11 arranged in parallel.
Further, the spur gear 10 is meshed with a pinion 22 fixed to the axle 21 of the rear wheels 20, 20 and a pinion 13 fixed to the support shaft 12, respectively, and this pinion 13 is meshed with a pinion fixed to the support shaft 2. It is meshed with 5. As a result, the driving force of the mainspring 4 is transmitted to the wheels 21, and the rear wheels 21
0,20 rotates.

Next, the support shaft 6 of the intermediate gear of the drive unit a
A crown gear 16 is fixed to one end 6a. Further, reference numeral 25 indicates a bearing portion formed near the front side of one side of the drive unit a, and this bearing portion 2
A support shaft 26 is rotatably attached to the support shaft 5, and pinions 27 and 28 are fixed to both ends thereof. One pinion 27 is attached to a crown gear 30 fixed to the inside of one of the front wheels 18, 18 which is fixed to the axle 17 of the front wheels, and the other pinion 28 is attached to a crown gear 30 that protrudes from the side surface of the drive unit a. Crown gear 16 fixed to spindle 6
are interlocked with each other.

Since the four-wheel drive traveling toy A is constructed as described above, first wind up the mainspring 4 of the drive unit a attached to the inside of the toy main body 1, and then release it. is transmitted to the rear wheels 20, 20 via the drive mechanism, and as the rear wheels 20, 20 rotate, the crown gear 16 fixed to one end 6a of the support shaft 6 constituting the drive mechanism also rotates. A pinion 28 meshed with this crown gear 16 and this pinion 28
A crown gear 30 fixed to the inner side of one of the front wheels 18, 18, which is meshed with a pinion 27 fixed coaxially with a support shaft 26 fixed to the shaft 26, rotates in the same manner, and the front wheels 18, 18 also rotate.

As mentioned above, the four-wheel drive traveling toy A drives the four wheels by connecting a simple transmission mechanism to the conventionally known drive unit a provided inside the traveling toy main body 1, so the manufacturing process is simple. is easier and cheaper. Further, the driving force of the drive mechanism of the drive unit a is transmitted to the axle 17 of the front wheels 18, 18 and the axle 21 of the rear wheels 20, 20.
Since 8, 20, and 20 are rotated at the same time, the driving force is greatly increased and the toy has excellent ability to overcome obstacles and climb hills, resulting in a running toy with much superior performance compared to conventional ones. . Furthermore, the range of play is expanded because it is possible to perform unusual driving.

In the above embodiment, the drive source of the drive unit a uses the mainspring 4, but it is not necessarily limited to this, and for example, a motor,
It may also be a friction or the like.
