Description

[Detailed Description of the Invention] The present invention relates to a whistle that can sequentially sound a plurality of whistles by slamming a toy body equipped with a plurality of whistles with different musical scales on the floor or desk.

2. Description of the Related Art Various toys have been known in which a toy body is equipped with a bellows and a whistle, and the bellows is compressed and deformed to produce a whistle. However, the sound in that case is single and lacks interest.

On the other hand, it uses a motor to blow air while playing a certain melody, but this is a big gimmick and is not suitable for children's toys.

Therefore, the present invention aims to provide a toy for children that can play different scales, or even a certain melody, simply by holding the handle and hitting the toy body continuously on the floor or desk. purpose.

The details will be explained below based on the drawings.

1 to 5 show a first embodiment of the toy according to this invention, which is constructed almost entirely of plastic material and is lightweight. Reference numeral 1 denotes a hollow toy main body whose overall shape resembles that of a bear cub.The interior of the main body 1 is divided by a partition wall 2 into a head cavity 1a and a body cavity 1b. 3 is an air supply means, which is the main body 1
It consists of a telescopic bellows 5 airtightly attached to the bottom wall 4 of the main body 1, and a handle 7 for striking the bellows fixed to the circumferential wall 6 of the main body 1, and the inside of the bellows 5 becomes a compressed air chamber 8. ing.

Reference numeral 10 denotes a hollow rotary drum disposed in the hollow body chamber 1b. As shown in FIG. 2, the rotary drum 10 is a pair of inverted L-shaped hollow drums extending from the bottom wall 4 of the main body.
The rotating drum 10 is rotatably supported by an air supply support 11 consisting of an inverted tube. The support 11 connects the air chamber 8 in the bellows with an air passage 12 formed in the rotating drum 10. Reference numeral 13 denotes a fixed drum which airtightly covers almost the entire outer circumferential surface of the rotating drum 10, and a slit-shaped through hole 14 is formed in the upper end of the fixed drum 13 over almost the entire length in the axial direction.
Four flutes 15, each with a different pitch, are fixed vertically to the front and rear of the upper end surface of the fixed drum 13, and the mouths 15a of the flutes 15 are connected in airtight communication with the slit-like through holes 14.

As shown in FIG. 3, the flute 15 is a vertical flute formed in the shape of a rectangular tube, and its tip end outlet 15b penetrates the partition wall 2 and faces the head cavity 1a. 1
Reference numeral 6 indicates an intake/exhaust port provided through the head cavity 1a, and this intake/exhaust port 16 is designed to resemble a bear cub's mouth.

A large number of ventilation holes 17 are transparently provided on the outer peripheral surface of the rotating drum 10 at predetermined phase intervals, corresponding to the blowing holes 15a of the whistle 15.

Reference numeral 18 denotes a drum rotation mechanism interposed in the front and rear central portions of the rotating drum 10;
is the ratchet gear 2 fixed to the rotating drum 10.
0, and an operating rod 21 that is fixed and erected on the inner bottom surface of the bellows 5, penetrates the bottom wall 4 of the main body, meshes with each tooth 20a of the ratchet gear 20, and rotates the ratchet gear 20.
and a stopper 22 made of a leaf spring, which is disposed opposite to the operating rod 21 and stops the ratchet gear 20 at a position where the nozzle 15a and the ventilation hole 17 communicate with each other. An engagement piece 24 is attached to the tip of the operating rod 21 and is constantly urged toward the gear by a torsion spring 23.

Reference numerals 25 and 25 denote telescopic arms attached to the left and right sides of the torso of the main body 1. Both telescopic arms 25 are shaped like the hands of a bear cub, and a pair of connecting pipes 26, 2 are connected to the air chamber 8 in the bellows.
6 and are connected to each other. Also, main body 1
The partition wall 2 and the bottom wall 4 are respectively provided with through holes 27 and 28 each having an intake valve.

Next, the operation of the above configuration will be explained. First, pattern 7
When you tap the bottom of bellows 5 with the
The air chamber 8 was compressed, and the compressed air in this chamber was sent to the blowing port 15a of the whistle 15 via the air supply branch 11, the air passage 12, one ventilation hole 17, and the through hole 14, and the whistle 15 was sounded. Afterwards, it is discharged to the outside from the intake/exhaust port 16. A part of the compressed air in the air chamber 8 at this time causes each telescopic arm 25 to extend through each connecting pipe 26.

When the whistle 15 finishes sounding, the bellows 5 returns to its original shape with its own elastic restoring force. At this time, the operating rod 21 of the drum rotation mechanism 18 rotates the ratchet gear 20 as shown in FIG. That is,
When the engaging piece 24, which is urged toward the gear side by the torsion spring 23, is lowered, the ratchet gear 20 is in the P position.
The ratchet gear 20 is rotated until the ratchet gear 20 is engaged with one tooth 20a of the gear and lowered to the r position where the engagement is released. When the rotary drum 10 is thereby rotated, the in-phase vent holes 17 communicate with the blowing ports 15a of the whistles 15 of other scales via the through holes 14. In this state, the stopper 22 engages with the other tooth 20a to position and stop the ratchet gear 20.

Then, when the bottom of the bellows 5 is struck again to compress the bellows 5, a whistle 15 of a different scale is sounded. When the operating rod 21 is raised, the engagement piece 24 comes into contact with one tooth 20a of the ratchet gear 20, which is stopped by the stopper 22, as shown by the imaginary line at the g position.

In this way, when the bottom of the bellows 5 is hit continuously, the four whistles 15 sequentially emit tones of different scales, and a certain melody is played while the rotary drum 10 rotates once.

If you observe this from the outside, it looks like the bear cub is humming a song and moving its hands to keep up the rhythm.

Note that the structure and rotation mechanism of the rotating drum 10, the overall shape of the main body 1, etc. are not limited to those of the above embodiments, and various other structures can be considered.

According to the toy according to the present invention as described above,
Bellows 5 provided at the bottom of main body 1 with handle 7 in hand
When the bellows 5 is continuously struck on a floor or desk, the bellows 5 expands and contracts to rotate the drum 10 intermittently by a certain amount, and a plurality of whistles 15 with different musical scales can be sounded in sequence.

Therefore, it is possible to play a monotonous melody. In this case, it is only necessary to compress and deform the bellows 5 by hitting the main body 1, and no power such as a motor is used to blow air to each whistle 15, and a special motor or other power is required to switch and ring multiple whistles 15 in sequence. It has become unnecessary.
As a result, there is an advantage that an interesting toy that makes sounds for young children can be provided at a low cost.
