Description

[Detailed description of the invention] This invention relates to a sounding device for vehicles, and especially when a child is riding on the vehicle and the vehicle is traveling at a relatively low speed while kicking the ground with its feet, the device emits sound intermittently over a short period of time. The present invention relates to a pronunciation device in which the pronunciation situation has an onomatopoeic effect of an engine.

BACKGROUND ART Conventionally, there are two types of vehicles of this type: electric ones and self-propelled ones that run by pedaling with the feet or kicking the ground. Electric powered vehicles are faster and mechanically easier to produce the onomatopoeia of the engine, but self-propelled vehicles cannot travel at high speeds, making it difficult to shorten the interval between sounds. Therefore, it was difficult to create an onomatopoeic sound similar to the sound of an engine because the gaps between the sounds were long. In particular, the conventional sound generating device of this type has a relatively simple configuration, in which a hammer plate made of a metal spring plate is hit with claws that are shifted in phase in the circumferential direction of the axle. Even if the number was increased, there was a drawback that the intermittent generation of sound could not be efficiently performed when the vehicle was traveling at low speeds.

The present invention improves the above-mentioned drawbacks, as in a child-driven vehicle, the sound can be emitted intermittently at very short intervals even when traveling at a leisurely speed, and therefore the engine It is possible to emit an onomatopoeic sound that is very similar to a sound, and it can also be emitted in the same way when moving forward or backward (which was not possible with conventional devices). It is characterized by

This invention will be explained below with reference to illustrated embodiments.

FIGS. 1 to 3 show examples of children's vehicles equipped with the sound generation device according to this invention. In this children's vehicle, an infant sits astride the vehicle body 1 and seats 2.

A thin spring part 18 of one arm of the clutch lever 16 is formed, and a pawl 18a protruding from the center of the spring part 18 is engaged with a positioning recess (not shown) (preferably provided at the bottom of the vehicle body) and fixed. As a result, a restoring force can be applied to the clutch lever 16. In addition, the rod 2 is inserted into the connecting hole 20 at the tip of the other arm portion 19 of the clutch lever 16.
3 ends are connected.

The sound producing wheel 11 and the clutch disk 13 which face each other on the axle 9 have clutch pawls 11 on their opposing surfaces that protrude in the axial direction on the same rotation radius.
a... and 13b. Each clutch pawl 11
When a and 13b engage, the rotation of the clutch disk 13 is transmitted to the sound producing wheel 11, causing it to rotate, and when the engagement is released, the rotation of the sound producing plate 11 is stopped, forming a clutch mechanism. . This clutch mechanism is operable by a manual lever 10.

Next, vertical engaging arms 21, 2 that individually engage with the teeth 12 on the outer peripheral surface of the sounding wheels 11, 11, 11.
Sound output levers 22, 22, 22 having 1, 21
is installed at a position directly above the sound producing wheels 11, 11, 11 so as to be swingable about a shaft 24. The sound producing lever 22 has upwardly directed prongs 22a, 22a at both ends of the horizontal lever, and its central portion is swingably supported by a shaft 24, and is located directly below the shaft 24, which is the center of swing. A vertical engaging arm 21 is adapted to engage with teeth of the sound producing wheel 11. The sound lever 22 is configured to maintain a stable weight balance with the engagement arm 21 in a vertical position.

Directly above the sound lever 22, 22, 22,
A sounding board 25 is installed which can be hit with mallets 22a, 22a.

FIG. 5 shows the structure of the sound generating device 4 in relation to the case 26. As shown in FIG. Axle 9 of rear wheels 8, 8
is a machine room 27 opened upward in the case 26.
has been penetrated through both side walls. One side of the sound wheel 11, which is rotatable with respect to the axle 9, is restrained by contacting the side wall of the machine room 27, and the other side is restrained in the axial direction by a pin (not shown) protruding from the bottom of the same machine room 27. Movement is restricted. A clutch lever 16 that moves a clutch disk 13 mounted on the axle 9 in the axial direction swings around a shaft screw 17 that is screwed into and fixed to a case 26. The arm portion 19 of the clutch lever 16 projects to the side of the case 26, and a rod 23 is connected to the arm portion 19.

The sound levers 22 are swingably attached to a shaft 24 fixed to a support frame 28. The support frame 28 is fixed to the case 26 by screws 29, 29 screwed into pilot holes 30, 30 of the case 26. In this way, the engaging arm 21 of each sound lever 22... is connected to the tooth 12 of the sound producing wheel 11 directly below.
It is in a state where it engages with.

A circular flange 31 that surrounds the opening of the machine room 27 stands upright on the upper surface of the case 26 .
A sounding board 25 such as a rubber sheet or a plastic sheet is laid flat on the flange 31, and the sounding board 25 is fixed by a presser ring 32 fitted into the flange 31. By doing so, the hammers 22a of the sound producing levers 22 are brought into a state where they strike the sounding board 25.

The case 26 is fixed to the vehicle body 1 with screws 33.

The method of using the sound generating device having the above configuration is that when a child sitting on the seat 2 astride a children's vehicle moves forward or backward by kicking the ground with both feet, the manual lever 10, which swings around the shaft 10a, is turned on. Operate in position. As a result, the clutch disk 13 is moved toward the sound producing wheel 11 via the clutch lever 16, and the clutch pawls 13a and 11a are brought into engagement. Therefore, along with the rear wheels 8, 8, the axle 9
When the clutch disk 13 rotates, the rotation is caused by the clutch disc 13
The sound is transmitted to the sound producing wheel 11 through the sound generating wheel 11 and rotates it. Therefore, the sound lever 22 is swung through the engaging arm 21 that engages with the tooth 12 of the sound wheel 11, and the swing causes the horn 22a to hit the sound plate 25. It produces a hitting sound.

There is no directionality in the engagement between the engaging arms 21 and the teeth 12, and therefore the same sound is generated when the child's vehicle moves forward or backward, producing an onomatopoeic effect, such as the sound of an engine, on the progress of the child's vehicle. play. Moreover, it is possible to generate onomatopoeia of various tones by changing the number of sound wheels 11 and sound levers 22 and the shape or pitch design of the teeth 12 on sound wheel 11.

When the manual lever 10 is operated to the off position, the clutch mechanism is disengaged and no sound is produced by any movement of the child's vehicle.

The sound generating device according to this invention is configured and used as described above, and this invention has the following effects.

In other words, in vehicles such as children's vehicles,
Even when running under its own power at relatively low speeds, it can generate sounds intermittently at short intervals, imitating an engine, and it can also generate the same sounds whether it is moving forward or backward, and the tones can be varied. It has flexibility in design and is excellent as a sound imitation device for children's vehicles, for example. Moreover, all the parts can be molded from synthetic resin, for example, and the construction does not use any steel springs, and the structure is simple, so it can be manufactured at low cost. Moreover, it has the advantage of having an excellent service life and fewer failures.
