In this Macrophone M, the user's breath, saliva and the like blow on the head 3, so it is easy to
become unsanitary, such as various bacteria proliferate. Therefore, in the related art, in order to
keep the head 3 clean, the microphone cap having the antibacterial action is attached to the head
3.
[0003]
Conventionally, as this type of microphone cap, for example, one disclosed in Patent Document 1
(Japanese Patent Application Laid-Open No. 8-205274) is known. As shown in FIG. 7, the
microphone cap 100 has a cup-shaped one covering portion 100 a covering one side of the head
3, a cup-shaped other covering portion 100 b covering the other side of the head 3, and one
covering portion 100 a And the hinge part 101 which connects the coating ¦ coated part 100b so
that opening and closing is possible is provided. On the other hand, the covering portion 100a
and the other covering portion 100b are each configured to include a frame 102 made of resin
and a cup-shaped antibacterial paper 103 to be attached to the frame 102.
[0004]
When the microphone cap 100 is used, the antimicrobial paper 103 is attached to the frame 102
of the first covering portion 100a and the second covering portion 100b in advance. Then, for
example, after using the microphone M, after wiping the microphone M with a cloth or the like,
the one coated portion 100a and the other coated portion 100b are opened through the hinge
portion 101, and the one coated portion 100a and the other coated portion 100b are headed The
first cover 100a and the second cover 100b are closed again via the hinge part 101, and the
head 3 is held. As a result, during storage, even if there are bacteria that are to be propagated in
the gaps of the windshield net 2 of the head 3 or the like, the propagation thereof is suppressed,
and the head 3 can be kept clean.

However, in this conventional microphone cap 100, since the antibacterial paper 103 must be
stuck to the frame 102 one by one when used, there is a problem that the operation becomes
complicated.
In addition, since the antimicrobial paper 103 is disposable, there is also a problem that waste is
increased. The present invention has been made in view of such problems, and it is an object of
the present invention to provide a versatile microphone cap that maintains the antibacterial
action for a long time and is easy to wear.
[0007]
In order to achieve such an object, the microphone cap of the present invention is a microphone
having a head formed in a substantially spherical shape with a windproof net at one end of a rodlike grip portion, the microphone formed removably on the head of the microphone. Cap,

other side of the head; and a hinge portion connecting the one covering portion and the other
covering portion so as to be able to open and close. A microphone cap which is attached to the
head when the one covering portion and the other covering portion are closed and which covers
the head and which can be removed from the head when the one covering portion, the other
covering portion, and the hinge portion It is set as the structure integrally formed.
[0008]
Thus, when using this microphone cap, for example, after using the microphone, after wiping the
microphone with a cloth or the like, one cover and the other cover are opened through the hinge,
and this one cover and the other cover are used. The parts are placed so as to sandwich the head,
and again the one covering part and the other covering part are closed via the hinge to hold the
head.
In this case, since the microphone cap can be attached only by opening and closing the one
covering portion and the other covering portion, the operability is extremely good and the
workability can be improved.
[0009]
During storage of the microphone with the microphone cap attached to the head, even if bacteria
attached to the windshield net of the head try to propagate in the gap of the windshield net, etc.,

In this case, if necessary, the one covering portion and the other covering portion are provided
with a holding portion for holding the base adjacent to the head of the holding portion at the
time of closing the one covering portion and the other covering portion. The cover is provided on
the inner side of at least one holding portion of the covering portion, and is constituted by a
recess in which the finger can be hooked from the edge of the holding portion. Since the hooking
portion is formed as a recess, it can be integrally formed and the structure can be simplified. In
addition, since it is provided inside the clasping part, it is easy to hook the finger, and it becomes
easy to transmit the force in the opening direction. Also in this point, the operability is improved
and the workability can be improved.
[0014]
Furthermore, the inner cover of the first and second cover portions can be adapted to correspond
to a microphone provided with a ring-shaped ridge that protrudes outward with the axis at the
approximate center of the head, if necessary. It is set as the structure which formed the
accommodation groove which can accommodate a convex line. Although different depending on
the microphone, there is a system in which a windshield net constituting the head is divided
vertically in the axial direction of the microphone, and the divided single members are connected
by a connecting portion. The connecting portion is provided with a ring-shaped ridge that
protrudes outward, and the receiving groove can receive the ridge. As a result, the situation in
which one coating portion and the other coating portion are not stuck on the ridges and closed
does not occur, and the head can be covered reliably. In addition, as compared with forming the
entire inside of the one covering portion and the other covering portion large in order to cover
the ridges, it is only necessary to form the accommodation groove, so it is possible to form the
whole as a whole accordingly. it can.
[0015]
According to the present invention, since it is possible to attach or detach the head by simply
opening and closing the one covering portion and the other covering portion, the operability is

Furthermore, the microphone cap C includes a finger hooking portion 30 for separating the one
covering portion Ca and the other covering portion Cb in the opening direction. The hooking
portion 30 is provided inside the holding portion 12 of at least one of the one covering portion
Ca and the other covering portion Cb (in the embodiment, the holding portion 12 of the one
covering portion Ca), and the holding portion 12 The recess 31 can be hooked with a finger from
the edge of the. The recess 31 is provided along the central longitudinal direction of the holding
portion 12. In particular, since the hooking portion 30 is formed by the recess 31, it can be
integrally formed on the holding portion 12, and the structure can be simplified. The recess 31
increases the gap between the wall surface of the recess 31 and the surface of the grip portion 1
of the microphone M, and enables insertion of a finger.
[0025]
Furthermore, the sizes of the one covering portion Ca and the other covering portion Cb, the size
of the through hole 14 and the size of the accommodation groove 15 can correspond to the
general-purpose vocal microphone M having the ridge 5 on the head 3 So, it is set with a margin.
Further, as compared with forming the entire inside of one covering portion Ca and the other
covering portion Cb larger to cover the ridges 5, it is only necessary to form the accommodation
groove 15, so the whole is formed compactly It is done.
[0026]
Therefore, when this microphone cap C is used, it becomes as follows. After using the
microphone M, after wiping the microphone M with a cloth or the like, as shown in FIG. 3 to FIG.
5, one covering portion Ca and the other covering portion Cb are opened via the hinge portion
10, and this one covering portion Ca and On the other hand, the covering portion Cb is disposed
so as to sandwich the head 3 and, as shown in FIGS. 1, 2 and 6, again, the covering portion Ca
and the other covering portion Cb are closed via the hinge portion 10 The engaging portion 21 is
engaged with the engaged portion 22 and locked, and the head 3 is held. In this case, since the
engaging projection 23 of the engaging portion 21 is engaged with the engaging hole 25 of the
engaged portion 22 by utilizing the flexible property of resin, operability is improved.
[0027]

Further, the head 3 of the microphone M has a ring-shaped convex 5 that protrudes outward,
and the convex 5 is accommodated in the accommodation groove 15. Therefore, the situation in
which the first covering portion Ca and the second covering portion Cb are not caught on the
ridges 5 and not closed is prevented, and the head 3 can be covered with certainty.
[0028]
Then, the microphone M is stored until it is used next time. During storage, even if bacteria
attached to the windshield net 2 of the head 3 try to propagate in the gap of the windshield net 2
etc., since the cap C is integrally formed of an antibacterial resin, its propagation is suppressed,
so The head 3 can be kept clean. In this case, since the engaging portion 21 and the engaged
portion 22 of the lock portion 20 are integrally formed of an antibacterial resin, the antibacterial
effect can be further enhanced.
[0029]
On the other hand, when using the microphone M for karaoke etc., the microphone cap C is
removed from the microphone M. At this time, the engagement between the engaging portion 21
of the locking portion 20 and the engaged portion 22 is released, and the first covering portion
Ca and the other covering portion Cb are opened via the hinge portion 10 and removed from the
head 3. In this case, since the engaging projections 23 of the engaging portion 21 are merely
removed from the engaging holes 25 of the engaged portion 22 utilizing the flexibility of the
resin, the operability is improved. Also, in this case, when releasing the engagement of the lock
portion 20 of the first covering portion Ca and the second covering portion Cb or opening the
first covering portion Ca and the second covering portion Cb, the finger is held in the recess 31
of the hook portion 30. It is possible to hold it and pull it, so that the operability is improved and
the workability can be improved. In particular, since the hooking portion 30 is formed into the
recess 31, the gap between the wall surface of the recess 31 and the surface of the grip portion 1
of the microphone M becomes large, which facilitates insertion of the finger and It is easy to pull
in, and it is easy to transmit the force in the opening direction. Also in this point, the operability
is improved, and the workability can be improved.
[0030]
As described above, since the microphone cap C can be attached to or removed from the head 3
01-05-2019
10
simply by opening and closing the first covering portion Ca and the second covering portion Cb,
the operability is extremely improved and the workability is improved. In particular, since one
coating Ca, the other coating Cb, the hinge 10, and the lock 20 are integrally formed of an
antibacterial resin, they can be repeatedly used over a long period of time, as in the prior art.
Since it is not necessary to perform troublesome work of exchanging the antimicrobial paper one
by one, the workability can be improved also in this respect. Furthermore, since it is not
necessary to use antimicrobial paper, it is possible to prevent disposable waste.
[0031]
In the above embodiment, the position of the hinge portion 10 and the position of the lock
portion 20 are not limited to those described above, and the hinge portion 10 is not the top of
the one covering portion Ca and the other covering portion Cb but the side portions. The lock
portion 20 may be provided on the side of the one covering portion Ca opposite to the hinge
portion 10 and the other side of the covering portion Cb. Further, in the lock portion 20, the
structures of the engaging portion 21 and the engaged portion 22 are not limited to the above.
