Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a megaphone used for cheering at baseball games, etc.

<Prior Art> Conventionally, megaphones have been used in place of loudspeakers to make voices reach far away. Therefore, the basic shape is a hollow truncated cone. However, recently, there have been many cases where the small diameter side has been enlarged to make it easier to hold in the mouth. Furthermore, so-called foldable megaphones that are extendable and retractable by connecting multiple short tubes have also been provided (Utility Model Publication No. 29-9015).
(No. 58-69899).

<Problems that the invention aims to solve> However, most of the conventional megaphones are designed to be used only as loudspeakers themselves, and even if the time, place, purpose, etc. change, there is no incidental effect on the megaphone. It was not possible to changeably attach special features, patterns, or other decorations. However, recently, for example, megaphones with the name and color of each baseball team that they support are preferred, and it has also become necessary for users to use megaphones with a different image each time they support a different team. There is. In other words, when to use the megaphone;
It has become increasingly necessary to use a megaphone by changing its color, pattern, and other incidental functions and decorations depending on the environment and situation of the place where it is used.

Therefore, the present invention solves the drawbacks of the above-mentioned conventional technology,
The purpose is to provide a megaphone that can be used by freely changing its color, pattern, and various other incidental functions and decorations depending on the situation.

<Means for Solving the Problems> In order to achieve the above object, the megaphone of the present invention has a megaphone main body and a large-diameter half of the outer circumferential surface of the main body in a double state and is detachable. To,
It consists of one or more jacket tubes that are fitted together, and the jacket tube has a notched groove portion for engagement at the small diameter end thereof, and a convex portion for engagement is provided on the outer surface of the megaphone body at a position corresponding to the notched groove portion. It is characterized by having the following.

<Function> According to the features of the present invention described above, when the jacket tube is inserted into the megaphone body and when it is removed,
You can change the color and pattern of the megaphone. Also, by using a jacket tube with patterns or marks cut out, it is possible to construct a megaphone with a completely different feel than when using only the megaphone itself. Furthermore, by adding an unusual function such as attaching a bell that makes a sound to the jacket tube and fitting this into the megaphone body, various additional and modifying functions can be attached and detached to the megaphone. Furthermore, by using a plurality of jacket tubes, the megaphone can be freely modified with desired modifications by replacing the jacket tubes depending on the time, place, and purpose.

In addition, when the jacket tube is fitted, the large-diameter half of the megaphone becomes double, making this part strong and durable depending on the usage situation. By separating the two, they become a pair of percussion instruments, and can be transformed into tools suitable for cheering, etc. other than loudspeakers.

To attach and remove the jacket tube, insert the jacket tube from the small diameter side (mouth receiving side) of the megaphone body, and once they are fitted, insert the notched groove on the small diameter end of the jacket tube into the convex part on the outside of the megaphone body. By engaging it, you can securely install it.
It does not come off either forward or backward, and it also reliably prevents the jacket tube from shifting or rotating in the circumferential direction. Therefore, even if you swing a megaphone around, it will not come off.

<Example> Fig. 1 is a partially sectional front view of a megaphone that is an embodiment of the present invention, Fig. 2 is a sectional view taken along the line A-A in Fig. 1, and Fig. 3 is a diagram showing a jacket tube with a stopper attached. It is a partially sectional front view.

In the figure, a megaphone body 1 and a jacket tube 2 are shown.
The expansion ratios of the tubes are made the same so that the jacket tube is closely fitted to the large-diameter side half of the outer peripheral surface of the megaphone body 1. Here, the term "half part" means about half, and the jacket tube may have a size that is appropriately longer or shorter than about half of the main body 1.

The jacket tube 2 is provided with a cut groove 4 at its small diameter end. The megaphone body 1 also has an engagement protrusion 3 at a position on the outer surface of the megaphone body 1 corresponding to the groove 4, that is, at a position on the outer surface of the megaphone body 1 where the small diameter end of the jacket tube 2 is located.
has been established. Megaphone body 1 in jacket tube 2
To install it, insert the large diameter side of the jacket tube 2 from the small diameter side of the megaphone body 1, and when the small diameter end of the jacket tube 2 passes over the protrusion 3 of the megaphone body 1 due to elasticity, Turn the jacket tube 2 appropriately to engage the cut groove 4 with the protrusion 3. As a result, the jacket tube 2 is fixed in complete contact with the large-diameter side half of the outer peripheral surface of the megaphone body 1. In this state, the megaphone will not come off even if you shake it. Of course, removal can be easily performed by reversing the above procedure.

The jacket tube 2 can be freely decorated with colors, patterns, letters, marks, etc. that are different from those of the megaphone body 1. Further, characters and symbols may be added in the form of cutouts.

Further, by preparing a plurality of jacket tubes 2 for one megaphone main body 1, the jacket tubes 2 can be freely selected and used depending on the time and place, use, and purpose.

In addition, as shown in Fig. 3, the jacket tube 2
A stopper 5 may be provided inside the large-diameter end portion. Since the inner diameter of the stopper 5 is smaller than the diameter of the large diameter end of the jacket tube 2, the elasticity of the material of the megaphone is used to fit and fix it. Removal can also be done using elasticity.

Further, a hole may be provided in the convex portion 3 of the megaphone body 1 so that a string can be passed through and hung.

Also, make a knob-shaped pocket in the jacket tube 2 and put a bell inside to use it as a tambourine.
It can be used as a cheering flag by attaching several rings and attaching small flags.

The diameters and expansion ratios of the megaphone body 1 and jacket tube 2 are not particularly limited. Therefore, for example, it can be made into a cheering bat-shaped megaphone that imitates a baseball bat.

Since megaphones are often swung around violently in the public, it is important that they are firmly attached so that the attachments do not come off and cause a nuisance to the public.
In this respect, when the megaphone of the present invention is swung, the centrifugal force acts in a safe direction, so there is no fear that the jacket tube 2 will come off.

Recently, megaphones have become indispensable for cheering at baseball games, along with musical instruments such as flutes and drums, but loud instruments such as drums are likely to be regulated as they cause discomfort to spectators. There is a need for an instrument that can replace the drum. The megaphone of this invention can be modified into a musical instrument with a mellow bell sound, which will be welcomed by the audience. In addition, by using the megaphone of this invention, you can become even more enthusiastic about your support and enjoy a sense of realism. From this point of view, it is a product of extremely popular value.

<Effects> The present invention has the above configuration, and according to the megaphone according to claim 1, the megaphone body and the large-diameter half of the side circumferential outer surface of the body are closely attached in a double state and can be attached and detached. It consists of one or more jacket tubes that can be freely fitted together, and the jacket tube has a notch groove for engagement at the small diameter end thereof, and a notch groove for engagement is provided on the megaphone body at a position on the outer surface corresponding to the notch groove. First, by fitting the jacket tube into the megaphone body, the jacket tube has a different color, pattern, character, mark, other decoration, or additional function than the megaphone body. By removing it, you can create a megaphone with a completely different feel. Second, by having multiple jacket tubes, you can replace the jacket tubes depending on the time, place, and purpose.
You can freely add desired modifications to the megaphone and use it. Third, when the jacket tubes are fitted together, the large-diameter half of the megaphone forms a double structure that is in close contact with each other, so it can be made sturdy depending on the usage situation, and when the two are separated, As a pair of percussion instruments, they can be transformed into tools other than loudspeakers suitable for cheering, etc.

Furthermore, in the present invention, the small-diameter end of the jacket tube is provided with a notched groove for engagement, and the megaphone body is provided with a convex part for engagement at a position on the outer surface corresponding to the notched groove, so that the two are fitted together. By engaging the cut groove and the convex part, it is possible to securely attach the two in close contact with each other, so that even if the megaphone is to be swung around, it will not come out either forward or backward. Furthermore, it is possible to reliably prevent the jacket cylinder from shifting or rotating in the circumferential direction.
