is opened, air flows into the room from the air inflow hole 47 provided in the cylinder 33, and the piston 36
By pressing the button, the pipe is ejected forcefully from the whistle 46, making it possible to make a sound and blow the sound. In this case, the volume within the resonance chamber 37 changes depending on whether the piston 40 is in the ascending or descending position, and a high pitched sound is emitted when the piston 40 is descending, and a low pitched sound is produced when the piston 40 is ascending. .

The whistle mouth 46 is provided with a member for opening and closing it. Next, this mechanism will be explained.

That is, as shown in the lower part of FIG.
The opening/closing member 50 of No. 6 has a structure in which a horizontal plate 51 for opening and closing the whistle 46 is connected to the lower end of a vertical plate 52, and the spring 44 is attached to the upper part of the vertical plate 52.
A protrusion 53 is provided to lock the lower end of. A horizontal plate 54 protrudes laterally from the middle part of the vertical plate 52,
An upward protrusion 55 that can be engaged with a second cam 58, which will be described later, is provided at its tip.

On the other hand, a pinion 25 provided coaxially with the large gear 23 meshes with a large gear 57 pivotally attached to the main shaft 14.

On one side of the large gear 57, the opening/closing member 5
A second cam 58 that is engaged with the upward protrusion 55 from below is in close contact with the second cam 58, and when the large gear 57 rotates, the opening/closing member 50 is moved by the plurality of uneven surfaces 59 provided on the outer peripheral surface of the second cam 58. By moving it up and down, the whistle 46 shown in FIG. 3 opens and closes.

Therefore, while the piston 36 continuously slides and sends air to the whistle 46, the horizontal plate 51 of the opening/closing member 50 moves along the shape of the uneven surface 59 of the second cam 58 to send air to the whistle 46. When opening and closing the uneven surface 5
9, an intermittent sound is emitted, and on the other hand, the piston 40 moves up and down in accordance with the shape of the first cam 20, and the volume of the resonance chamber 37 changes, so the pitch of the intermittent sound also changes. be.

Next, parent bird 3 and baby bird 4 as animal doll bodies,
The operating mechanism 60 that moves 4 will be explained.

A small gear 61 meshes with the large gear 57 below. A large gear 62 is provided coaxially with the small gear 61 and is mounted on a common shaft 63. A gear 64 meshes with the large gear 62. The gear 64 and an eccentric disk 65 are mounted on a shaft 66. The eccentric disk 65 is a moving frame 67
When the eccentric disk 65 rotates, both side walls 68a, 68a of the hole 68
The movable frame 67 is moved left and right by engaging with the movable frame 67. Further, an engaging piece 70 having a long groove 69 is projected from the moving frame 67, and an eccentric pin 72 protruding from the lower end of the shaft tube 71 is engaged with this engaging piece 70. Axial tube 7
1 is fitted with a base shaft 3e of the parent bird 3, which is a swinging body, so that when the moving frame 67 moves horizontally, the parent bird 3 rotates left and right.

On the other hand, a semicircular plate 8 is provided on the side surface of the second cam 58.
A semicircular hole 81 formed in a partially toothed gear 82 corresponding to a third cam is fitted into this semicircular plate 80 so as to rotate together.
The teeth 83 of the intermittent gear 82 intermittently form a plurality of teeth 83 corresponding to the protrusions 59 of the second cam 58 . It was established.

Note that the cutouts are made on the inside of the plurality of teeth 83 to give elasticity to each tooth 83, so that when meshing with the opposing gear begins, the peaks of the teeth collide. In such a case, the purpose is to allow them to escape from each other smoothly and achieve smooth engagement.

The gear with missing teeth 82 is a pair of large and small gears 84 and 85.
It meshes with the small gear 84 inside. Further, one large gear 85 meshes with a large gear 86. A plurality of protrusions 87... (four each in the figure) are provided on one side of each of the large gears 85, 86, and engage with one end of a rotating member 88, which will be described later, to intermittently push it. It is something to raise.

The rotating member 88 is comprised of a pair of members arranged symmetrically on the left and right sides. That is, the shafts 89 at both ends
It is composed of a cylindrical body 90 that projects from the cylindrical body 90 and a push-up plate 91 that protrudes rearward from the inner surface of the cylindrical body 90. A hole 92 is provided on the upper surface of the cylindrical body 90 into which the base shaft 4a of the baby bird 4 is fitted, and stoppers 93, 93 for regulating the rotation of the cylindrical body 90 are protruded from the outer surface. Rotation in the front-back direction is restricted by a protruding piece (not shown) fixed to the inner surface of.

A spring member 94 having both ends fixed is in contact with the upper surface of the push-up plate 91 that is integrated with the cylindrical body 90.
1 is biased downward. This pressing plate 91, 91
The push-up protrusions 87 of the large gears 85 and 86 are engaged with the lower surface of the tip. Therefore, large gear 8
5 and 86, the plurality of push-up protrusions 87 sequentially push up the lower surfaces of the rear ends of the push-up plates 91 and 91 intermittently against the spring force. Moreover, the push-up plates 91, 91, once pushed up, are returned to a downward movement due to spring elasticity. Therefore, when the cylindrical bodies 90, 90 rotate in the front-back direction, the baby birds 4, 4, which are animal doll bodies, swing back and forth accordingly.

As mentioned above, the parent bird 3 is constantly rotated in the left and right direction by the drive mechanism 10, while the baby birds 4, 4
is intermittently oscillated by the operating mechanism 60, and at the same time, the sound generating mechanism 32 emits a sound.

As explained above, according to the blowing toy of the present invention, a flute is provided in the resonance chamber with variable volume provided in the cylinder, and the piston emits sounds of high and low pitches intermittently, and multiple Each of the animal doll bodies is made to perform different actions, so for example, if you engage it with the frame of a crib in which an infant is sleeping and move it, the baby bird next to the parent bird will cry while shaking its small body.
This state is so cute that infants can play with it on their own with satisfaction.
