[Prior art and its problems]

By expanding and contracting the bellows part called the bellows body, the body sucks in or sends out wind, and by interposing a whistle in this wind intake and discharge part, you can enjoy the sound generation. Accordion toys have been known for some time.

However, the above-mentioned accordion toys were only used to provide auditory entertainment through the sound of the whistle, and no further effects could be expected.

[Purpose of invention]

The present invention is an attempt to address these problems in view of the above circumstances, and it goes without saying that by using the accordion toy and its original usage, it is possible to obtain auditory enjoyment from the generation of sound. , the floating body housed inside the rotating mechanism installed adjacent to the sound generating mechanism moves at the same time as the sound is generated, so that visual enjoyment can also be obtained, and the expansion and contraction of the bellows body The purpose is to provide an accordion toy that can exhibit multiple usage effects through a single operation.

[Key points of the idea]

In the present invention, handles are attached to both ends of a bellows body that is freely expandable and contractible, and a whistle that is blown by the movement of air is attached to a mouth provided at one end of the bellows body that allows air to flow in and out. At the same time, a rotating mechanism for a floating body having a space in which a floating body made of a lightweight sphere or the like can move is attached adjacent to the attachment part of the flute, and both sides forming the rotating mechanism for the floating body are formed. The key point of the design is that each wall has several slanted air circulation holes.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

The accordion toy of the present invention has a bellows body with one end closed and the other end open.
, a handle 2 attached to one closed end of the bellows body 1, and several floating bodies 4 made of lightweight spheres or the like inside, attached so as to face the open mouth side of the bellows body 1. The basic structure is a combination of a rotating mechanism 5 that freely accommodates a rotating mechanism 5, a whistle 72 that blows due to the air flow caused by the expansion and contraction of the bellows body 1, and a handle 3 that is attached to the outside of the rotating mechanism 5. There is.

The bellows body 1 is made of a cylindrical body made of a synthetic resin thin film, etc., and has bellows-like folds 11...11 having a serrated cross section on the peripheral edge thereof, so that it can be freely expanded and contracted. Locking protrusions 12 and 13 for fitting and locking the handles 2 and 3 are formed protruding from both ends of the cylindrical body.

Of the two locking protrusions 12 and 13, the locking protrusion 12 formed at one end to which the handle 2 is attached is closed to prevent air circulation, and the locking protrusion 12 formed at the other end is closed. The protrusion 13 is formed with an inlet/outlet port 14 through which air flows in and out.

15 is an annular groove for locking formed on the peripheral edge of the locking protrusions 12 and 13, and locking holes 22, 32 formed in the center of the bases 21, 31 forming a part of the handle 2 or 3. After fitting the locking protrusions 12 and 13 into the bellows body, the locking rings 23 and 33 are engaged inside the locking holes 22 and 32 to secure the bellows body and the base. There is.

The handle 2 is composed of a base 21 that is attached to the closed end of the bellows body 1 and fixed thereto, and a handle 24 that is rotatably attached to the outside of the base 21.

The base 21 described above is composed of a dish-shaped base 21a to which the end of the bellows body 1 is directly attached and fixed, and a crown body 21b attached to the upper surface of the dish-shaped base 21a. 2 is a screw 25 on this crown body 21b.
It is rotatably attached via the

Further, the other handle 3 includes a base 31 for attaching to the end of the bellows body 1 and fixing it;
It is composed of a rotation mechanism 5 having an annular space in which several floating bodies 4...4 made of lightweight spheres etc. can be rotated by wind pressure, and a handle 34 attached to the outside of the rotation mechanism 5. are doing.

Note that the movable bodies 4...4 are not limited to spheres as illustrated, but may be of any shape or material as long as they can be movable within the annular space by wind pressure. No problem.

As illustrated in detail in FIGS. 2 and 3, the rotation mechanism 5 having an annular space has a cylinder 51 in the center.
A substrate 52 with a protruding structure attached to the substrate 52,
It is constructed by combining a dish-shaped plate 54 having a through hole 53 in the center thereof into which the tip of the cylinder 51 can fit.

In the case of the above-described structure, it is necessary to connect the distal end of the column 51 and the dish-shaped plate 54 so that they can maintain close contact to prevent air from leaking from the combination.

Note that the tip of the cylinder 51 described above does not necessarily have to be assembled by fitting into the through hole 53 formed in the plate-shaped plate 54 as shown in the illustration; When combined so as to face each other, the central part of the space surrounded by these is partitioned by the cylinder 51, thereby forming an annular space (doughnut-shaped space) around the outer periphery of the cylinder 51. It is sufficient that the structure is such that several floating bodies 4...4 can rotate and move within this annular space according to the air flow (wind pressure).
(For example, a combination of a base plate 52 with a cylinder 51 protruding thereon and a dish-shaped plate 54 with no through holes etc. is used, and the upper end of the cylinder 51 is in close contact with the inner surface of the dish-shaped plate 54. The substrate 52 and the dish-like plate 54 have a width defined by the outer circumferential edge of the cylinder 51 and the outer circumferential edge of the substrate 52 along the center line in the width direction thereof. along the middle part)
Air circulation holes 6...6 are spaced at regular intervals, respectively.
Alternatively, the air circulation holes 6...6, 6'...6', in which a large number of holes 6'...6' are bored, are arranged around the circumference of the plate, as shown in the enlarged cross-sectional view drawn out by the arrows in Fig. 3. The holes are formed so as to have an inclination along the direction, thereby imparting directionality to the flow of air blown out.

In addition, in the embodiment, the air circulation holes 6...6 formed in the substrate 52 and the air circulation holes 6'...6' formed in the plate-like plate 54 are formed so that their inclination directions face the same direction. However, the direction of inclination is not limited to this, for example, the direction of inclination is
When the inclination direction of the air circulation holes 6...6 formed in 2 is set as a rightward inclination, the air circulation holes 6'...
It is also possible to set the direction of inclination of 6' to the left, contrary to the above.

Reference numeral 7 designates a mounting plate for the flute 72, which is formed into a shallow dish shape by forming a low flange portion 73 on the periphery, and the flute 72 is attached to a through-hole portion 71 bored in the center of the plate. That's what I do.

Reference numeral 74 denotes a shallow cylindrical recess formed on the back surface of the through hole 71 so as to close it, and a through hole 74' for guiding the air that has passed through the whistle 72 is formed in the peripheral wall thereof. There is.

The whistle attachment plate 7 formed into a shallow dish shape is formed to have a shape larger than a circle surrounded by a line connecting the air circulation holes 6'...6' formed in the dish plate 5. By attaching the flange 73 in close contact with the back surface of the dish plate 54, the air guided from the circulation holes 6'...6' can pass through the air passage formed in the center. After being concentrated in the hole 71, it can flow out through a through hole 74' formed in the peripheral wall of a shallow recess 74 that is closed off.

8 is a protective cap for the whistle 72, which prevents the whistle 72 attached to the air passage hole 71 from coming off the mounting plate 7, and has a notch formed in the circumferential body of the protective cap 8 for air circulation. The guide portion 81 serves to guide the flow of air passing through the whistle 72.

The flute 72 is constructed with the same mechanism as the sounding part of a harmonica, and includes a reed plate 72a that emits sound by air flowing in from the front side, a reed plate 72b that emits sound by air flowing in from the back side,
72b are attached respectively.

Reference numeral 35 denotes an air circulation hole formed at the peripheral edge of the handle 3.

[Operation of the idea]

The present invention configured as described above operates as follows.

The present invention can be used in the same way as the accordion, which is a conventionally known musical instrument.In other words, the two functions described later can be achieved simultaneously by a child holding the handles 2 and 3 with both hands and simply operating the bellows body 1 to expand and contract. can be done.

* Usage as an accordion (generating sound) When a child holds handles 2 and 3 with both hands and operates the accordion body 1 to unfold it,
Air sucked in from the air circulation hole 35 formed at the peripheral edge of the handle 3 passes through the air flow guide part 81 of the protective crown 8 and reaches the whistle 72, and then reaches the attachment part of the reed plate 72a attached to the whistle 72. By passing through the reed plate 72a, the reed plate 72a is vibrated and the whistle is blown. (The air that has passed through the reed plate 72a is guided in the direction of the rotating mechanism 5 that follows it, and performs the action described later.) Furthermore, when the bellows body 1 is operated to contract, the rotating mechanism 5 The air sent in from the side (the side of the board 52) passes through the attachment portions of the reed plates 72b, 72b attached to the whistle 72, thereby vibrating the reed plates 72b, 72b, causing the whistle to sound.

Therefore, when the operation of expanding and contracting the bellows body 1 is to operate in the direction of expanding the body (operation in the direction of extension)
by the vibration of the reed plate 72a, and in the case of operation in the contraction direction (operation in the contraction direction) by the vibration of the reed plates 72b, 72b, and in both cases by the blowing of the whistle 72. Sound can be generated (played).

* Operation of the rotating mechanism The rotating mechanism 5 operates both when the bellows body 1 is extended and when it is contracted.
An example in which the image is expanded will be explained.

First, when the handles 2 and 3 are gripped with both hands and the bellows body 1 is operated to unfold, the air sucked in from the air circulation hole 35 formed at the periphery of the handle 3 is formed in the protective crown 8. The air reaches the whistle 72 through the air circulation guide part 81 and passes through the attachment part of the reed plate 72a attached to the whistle 72, thereby vibrating the reed plate 72a and making the whistle 72 blow.

The flow of air that blows the whistle 72 is carried out through an air circulation hole 71 made in the center of the mounting plate 7 of the whistle 72, and a hole 74 made in the peripheral wall of a shallow recess 74 formed on the back side of the hole 71. Air circulation holes 6' formed in the plate-shaped plate 54 constituting the rotation mechanism 5
...reaches 6'.

Since the air circulation holes 6...6 formed in the dish-shaped plate 54 are formed with an inclination toward the circumferential direction, the air passing through them has an annular space along the inclination direction. It is rapidly fed into the rotating mechanism 5, and as a result, several floating bodies 4 accommodated inside the rotating mechanism 5...
4 rotates and moves in an annular space formed around the cylinder 51 while following the flow of air.

The air generated by rotating the movable bodies 4...4 in the annular space flows from the air circulation holes 6...6 formed in the base plate 52 located on the opposite side of the dish-shaped plate 54 to the outside (bellows (direction of cylinder 1).

The air sent out from the circulation holes 6...6 of the base plate 52 flows into the bellows body 1 through the air inlet/outlet 14 formed at the end of the bellows body 1 whose end is fixed to the base 31.
It is sent inside and stored.

If necessary, the feeding of air into the bellows body 1 can be continued until the limit length that the bellows body 1 can extend.

The above is the operation accompanying the extension operation of the bellows body 1.

* Generation of sound and operation of the rotating mechanism when the bellows body 1 is contracted When the bellows body 1 is extended to its limit length,
Alternatively, if it is contracted in accordance with the operating principle of an accordion during the extension, the floating bodies 4...4 housed inside the rotation mechanism 5 can be rotated again by the operation opposite to the above. You will be able to do this. That is, when the bellows body 1 starts to contract, the air stored in the bellows body 1 is sent out from the air inlet/outlet 14 formed at the end of the bellows body 1
Air is guided to the air circulation holes 6...6 from the back side of the substrate 54 located in front of the base 31 to which the air is fixed.

The air circulation holes 6...6 formed in the substrate 52 are formed to be inclined in the circumferential direction like those in the dish plate 54, so the air passing through them follows the inclination direction and flows inside the rotating mechanism 5. As a result, the several floating bodies 4...4 housed inside the rotating mechanism 5 rotate round and round around the cylinder 51 while following the air flow. and move around. (In the embodiment, since the air circulation holes 6...6 are inclined to the left, the movable bodies 4...4 are rotated to the left, but if this inclination direction is set to the opposite direction) (Naturally, the movement of the floating bodies 4...4 is in the opposite direction) The flow of air that caused the floating bodies 4...4 to rotate freely is caused by the air flow formed in the plate-like plate 54 located on the side facing the substrate 52. It is guided to the communication holes 6'...6' and sent out from the communication holes 6'...6'.

The flow of air sent out from the circulation holes 6'...6' is guided to the air circulation hole 71 formed in the center of the mounting plate 7 of the whistle 72, and causes the reed plates 72b, 72b of the whistle 72 to vibrate. After blowing this, the handle 3 is removed from the air circulation guide part 81 of the protective crown 8.
The operation ends when the air is diffused to the outside through the air circulation part 35 formed at the peripheral edge of the air, and these operations are repeated thereafter.

[Effect of idea]

The effects of the present invention configured as described above are as follows.

(1) By operating the handles 2 and 3, the bellows body 1 can be expanded and contracted, and by utilizing the airflow caused by the expansion and contraction of the bellows body 1, an accordion effect can be obtained in which the whistle 72 is blown. It can bring out auditory enjoyment.

(2) A rotating mechanism 5 having an annular space is interposed between the bellows body 1 and the handle 3, and several floating bodies 4...4 are housed inside the rotating mechanism 5.
When an infant performs an accordion operation, the floating bodies 4...4 accommodated in the annular space rotate in a predetermined direction in accordance with the accompanying wind movement.

As a result, the two operations of blowing the whistle 72 and moving the movable bodies 4...4 can be automatically performed by a single operation of expanding and contracting the bellows body 1. We were able to demonstrate an extremely excellent effect that provided both entertainment and auditory enjoyment.

(3) Substrate 52 and plate-like plate 54 that constitute the rotation mechanism 5
Since the air circulation holes 6...6 and 6'...6' are formed at an angle, the flute 72 can be used both when contracting the bellows body 1 and conversely when expanding the bellows body 1. The blowing sound and the rotational movement of the floating bodies 4...4 can be performed.

(4) When the air circulation holes 6...6 formed in the base plate 52 and the air circulation holes 6'...6' formed in the dish plate 54 are inclined in the same direction, the bellows body 1 Regardless of the expansion/contraction direction, the floating bodies 4...4 move in the same direction, but if any of the air circulation holes described above are tilted in the opposite direction, they will move due to the extension of the bellows body. The direction of movement of the floating bodies 4...4 and the direction of movement of the floating bodies 4...4 which move due to the contraction of the bellows body 1 can be made to move in completely opposite directions, providing visual enjoyment by changing the direction of movement. can be doubled.

(5) When children try to extend or contract something like the bellows body 1, it is often seen that children twist their left and right hands to extend or contract the bellows body 1. Since the handle 2 attached to one end of the handle is configured to be rotatable, the above-mentioned expansion and contraction operations can be easily performed.
