Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a running toy with a sounding body that emits a pseudo-sound such as an engine sound while running.

[Conventional technology]

2. Description of the Related Art In order to add various tastes to traveling toys, there are known ones that sound a siren or flash lights. This type of additional functionality is generally
Applied to battery-powered traveling toys. For this reason,
This method cannot be applied to traveling toys having other drive sources, such as a spring type or a flywheel type, and has limited versatility.

Further, the sounding function of a siren or the like requires relatively expensive parts, which increases the cost of the product. Further, as an example of a running toy whose pronunciation function is performed using a voice synthesis circuit or the like, there is one disclosed in Public Utility Model Publication No. 168395/1983. This traveling toy has the disadvantage of increased cost as described above, and also has the problem of unnatural sounds produced electrically.

[Problem that the invention attempts to solve]

Therefore, the present invention provides a traveling toy with a sounding body that can be adapted to any type of drive source and that can produce sounds extremely similar to the engine sound of a traveling object at a low cost.

[Means for solving problems]

The operating plate is pivotally supported on the frame of the traveling toy, allowing it to swing freely.
A striking member is formed on this actuating plate. The actuating plate is designed to reciprocate up and down in response to the rotational power of the driving device of the traveling toy. Furthermore, a hollow sounding body is swingably mounted on the frame. A diaphragm is provided on the lower surface of the hollow sounding body, and this diaphragm faces the striking member.

[Effect]

There are various methods of converting the rotational power of the drive device into reciprocating motion of the actuation plate, but in any case, the rotational power from a motor, spring, flywheel, etc. is mechanically transmitted to the actuation plate. The actuating plate and its striking member perform vertical reciprocating motion as the driving wheel rotates while the vehicle is running. Due to this reciprocating movement, the striking member hits the diaphragm of the hollow sounding body. The hollow sounding body is swingably placed on the frame, and is moved upward when hit by the striking member. When the striking member returns to its original position, the hollow sounding body moves from above to below by its own weight and returns to its original position. At this time, the lower surface of the hollow sounding body and the frame collide to generate a sound. In this way, sound is generated twice: when the striking member and the hollow sounding body collide, and when the hollow sounding body collides with the frame, which is the mounting surface. Therefore, since a different sound is generated, it is possible to make the sound extremely similar to, for example, the engine sound of a traveling vehicle.

In this way, since the configuration converts the rotational driving force of the traveling toy into vertical and reciprocating motion of the striking member of the actuating plate, it can be applied to any type of drive device. In addition, since a diaphragm is attached to the hollow sounding body, the tone produced changes depending on the size and material of the hollow sounding body, and the size and material of the diaphragm. For example,
It can generate a sound similar to the sound of an engine while driving. In addition, since the hollow sounding body is configured to be swingably mounted on the frame, it does not suppress vibrations when the hollow sounding body produces sounds, and has good effects in terms of sound quality and volume. It's on. Furthermore, since it is mounted so as to be swingable, it is possible to generate sound by the collision between the mounting surface and the hollow sounding body, and it is possible to generate two different types of sounds.

〔Example〕

A preferred embodiment of the traveling toy with a sounding body of the present invention will be described below with reference to FIGS. 1 to 3.

FIG. 1 shows an example in which the traveling toy with a sounding body of the present invention is applied to a four-wheeled vehicle, and is a perspective view with the body removed. In the figure, chassis 1
A front wheel 2 and a rear wheel 3 are rotatably supported on a chassis 1. The rear wheel 3 serves as a driving wheel and is connected to a drive device via its axle 4. The drive device is configured inside and outside the frame 5 provided on the chassis 1 of the traveling toy, and in this embodiment has a spring-type drive source.

This drive device will be explained with reference to an exploded perspective view (FIG. 2) showing the inside of the frame 5 in detail. A spiral spring 6 is disposed approximately at the center of the frame 5.
One end of the spiral spring 6 is fixed to the frame body, and the other end is fixed to the winding shaft 7. The winding shaft 7 is rotatably supported by the frame 5, and a ratchet pawl 8 is fixed thereto. A first gear 9 having a ratchet gear on its inner peripheral surface is provided at the periphery around which the ratchet pawl 8 rotates. The first gear 9 is the winding shaft 7
It is loosely fitted into the shaft and rotates in one direction only in the direction of the arrow in the figure. The first gear 9 is a second gear pivotally supported by the frame 5.
The second gear 10 meshes with the third gear 11. This third gear 1
A first drive gear 12 is fixed to the first shaft outside the frame 5. The first drive gear 12 is the second drive gear 1 fixed to the axle 4 of the drive wheel 2.
It meshes with 3. Therefore, these spring springs 6, the winding shaft 7, the ratchet pawls 8, the first to third
gears 9, 10, 11, first to second drive gears 1
Reference numerals 2 and 13 constitute a drive device for the traveling toy, which rotates each gear in the direction of the arrow shown in the figure.
Note that the gear indicated by the reference numeral 26 meshes with the first gear 9 to apply an appropriate rotational load to the first gear 9.

Reference numeral 14 indicates an actuating plate. This actuating plate 14 is
It is rotatably supported by the frame 5. Specifically, it is loosely fitted to the shaft 15 of the second gear 10 via the through hole 16 thereof. A protruding striking member 17 is provided at one end of the actuating plate 14 . Furthermore, a long hole 18 is formed in the center. A mechanism in which the actuating plate 14 is swingably supported by the frame 5 and reciprocates up and down in response to the rotational driving force of the drive device described above will be described with reference to FIG.

In FIG. 3, reference numeral 14 denotes an actuating plate, which is pivotally supported by the shaft 15 of the second gear 10, as described above, so as to be swingable. Therefore, the first gear 9 is moved downward with this shaft 15 as a fulcrum.
It is supported by the rim 19 of the rim 19 through the elongated hole 18.
On the other hand, a protrusion 20 is formed on the opposite side of the striking member 17, and this protrusion 20 engages with a tooth groove 21 of the third gear 11. Therefore, when the third gear 11 rotates in the direction of the arrow in the figure, its tooth groove 21 rotates the protrusion 20 around the shaft 15 in the direction of the arrow. Therefore, the striking member 17 moves upward as shown by the arrow. When the tooth groove 21 and the projection 20 are disengaged, the actuating plate 14 returns to the lower position supported by the rim 19. By repeating such an operation, the actuating plate 14 and therefore its striking member 17
It can be seen that the rotational driving force of the drive device (the rotational driving force of the third gear 11) causes vertical reciprocating motion. Note that, instead of the third gear 11, it is also possible to use a cam or the like to cause the actuating plate 14 to reciprocate up and down. Further, instead of the rim 19 and the elongated hole 18, a support rod or a stand or the like may be provided below the support plate 14 to restrict the downward movement of the actuation plate 14.

Furthermore, as shown in FIGS. 2 and 3, a hollow sounding body 21 is swingably mounted on the frame 5. That is, the shaft 22 fixed to the frame 5 is fitted into the through hole 23 thereof. This hollow sounding body 21 is made of, for example, a plastic material, and has a relatively thin membrane diaphragm 24 stretched over its lower surface (see FIG. 3). This diaphragm 24 faces the above-described hitting member 17 via an opening 25 formed in the frame 5. Therefore, the vibration plate 24 is intermittently struck by the vertical and reciprocating movement of the striking member 17. Note that the hollow sounding body 21 is placed on the upper surface of the frame body 5, and is configured not to move downward therefrom. This configuration may also be such that, for example, the hollow sounding body 21 is provided within the frame 5 and a separate support rod or stand is provided below the hollow sounding body 21. In short, when the actuating plate 14 is moved downward,
It is sufficient that a certain distance exists between the striking member 17 and the diaphragm 24. With this configuration, two types of sound can be obtained: one when the striking member hits the hollow sounding body, and the other when the hollow sounding body hits the frame or the like which is the mounting surface.

In the embodiment having the above configuration,
When the winding spring 6 is wound up and the running toy is run, the tooth grooves of the third gear 11 push down the protrusion 20. That is, the actuating plate 14 is rotated clockwise around the shaft 16. Therefore, the striking member 17 strikes the diaphragm 24, causing the hollow sounding body 21 to generate sound and pushing it upward. As the third gear 11 further rotates, its tooth groove 21 and protrusion 20
When disengaged, the actuating plate 14 falls downward to the position of the rim 19. Therefore, although the hollow sounding body 21 also moves downward, it is placed on the frame 5, so that a gap is maintained between the diaphragm 24 and the striking member 17. After this, the same operation is repeated to produce continuous sound.

[Effects of the Invention] As described above, the actuating plate is swingably supported by the frame, and the hollow sounding body is swingably mounted on the frame. The operating plate is configured to reciprocate up and down in response to the rotational driving force of the driving device for the traveling toy. Further, the striking member of the actuating plate strikes a diaphragm provided on the lower surface of the hollow sounding body. Therefore, the present invention can be applied to all types of traveling toys regardless of the type of drive source of the drive device.

Further, the actuating plate and the hollow sounding body are mechanical parts, and their structure is simple, which has the effect of reducing the increase in product cost.

Furthermore, the hollow sounding body is hollow inside and has a structure in which a diaphragm is partially stretched. Therefore, by changing their shape and material, it is possible to select various tones, pitches, volumes, etc.
Furthermore, since the hollow sounding body itself is not fixed to the frame, vibrations of the generated sound are not suppressed, resulting in good sound quality and volume. Furthermore, after the striking member strikes the hollow sounding body, the hollow sounding body moves upward, but then falls downward under its own weight. For this reason, the hollow sounding body produces sound even when it hits the frame which is the mounting surface. Therefore, two types of sounds with different sound quality are generated, which has the effect of being extremely similar to the engine sound of a traveling vehicle.
