Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a keyboard harmonica singing holder for holding a singing mouth of a wind tube connected to a musical instrument body of a keyboard harmonica.

[Conventional technology]

Japanese Utility Model Laid-Open No. 64-6695 proposes a mouthpiece holder that can be held hygienically without directly placing the mouthpiece of a wind pipe used for a keyboard harmonica on a desk or the like.

That is, this mouthpiece holder is provided with a fitting groove facing the outer surface of the connection port for playing the blow tube downward, and a base portion is formed on the side of the fitting groove, and the base portion is formed above the base portion. It has a structure in which a concave portion for fitting the song mouth is provided.

[Problems to be solved by the device]

However, according to the above-mentioned conventional example, it cannot be applied to the wind pipes having different diameters, and there is a problem in that it is versatile. In addition, the base part is provided with the intention of stably mounting the main body of this holder on the table, but the installation position (height) of the connection port for playing the wind pipe to the instrument body is not always constant. Since it is not limited, there is also a drawback in that the holder itself can be mounted at an inclination, especially when the mounting position is set higher than usual.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, in the present invention, in a keyboard harmonica song holder that holds the mouthpiece of a wind instrument connected to the musical instrument body of the keyboard harmonica, a pair of left and right clamping pieces are opened and closed with respect to each other with a common rotation axis. In addition to possible combination, it has spring means for urging the sandwiching piece in the closing direction, and each opposing one end of the sandwiching piece serves as a sandwiching portion for sandwiching a predetermined portion of the brass tube, and between the other ends on the opposite side. It has a structure that holds the song.

[Action]

According to this structure, it can be applied to various kinds of wind pipes regardless of the diameter of the wind pipe and the mounting position of the connection port for playing the table. Further, since the mouthpiece holder only needs to be sandwiched, it can be easily attached not only to the wind pipe but also to a pipe leg of a performance stand, for example.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1 and FIG. 2, the keyboard harmonica mouthpiece holder 10 includes a pair of left and right holding pieces 11 and 11 which are combined so as to be openable and closable with a common rotary shaft 12. In this embodiment, since each sandwiching piece 11 has the same structure,
Hereinafter, one of them will be described.

The sandwiching piece 11 is made of a rectangular synthetic resin plate, and has a bearing surface 13 for the rotating shaft 12 at approximately the center on the inner surface side facing each other.
Is equipped with. In this case, the bearing surface 13 has an arc angle of 90 degrees. On both sides of the bearing surface 13, the rotary shaft 12
Protrusions 14, 14 protruding in the axial direction of are formed.

With the bearing surface 13 as a boundary, the one end side of the sandwiching piece 11 is a wind pipe 31.
It is a holding portion 15 for the, and the other end portion on the opposite side is a holding portion 16 of the song mouth 32. According to this example, the sandwiching portion 15 is formed with a gutter-shaped curved surface 15a. In addition, the holding portion 16 is formed with ribs 16a, 16a for frictionally holding the root portion 31b of the blow tube on the side of the mouth 32.

As shown in FIG. 3, the rotary shaft 12 has a male member 17 and a female member 18 which are fitted and combined with each other. The male member 17 and the female member 18 are provided with cylindrical portions 17a and 18a which are combined to form one cylindrical surface. In this case, the male member 17 and the female member 18 are transparently formed in the female member 18. Hole 19
A connecting shaft 20 that fits inside is provided. Also, the member
Flanges 21, 21 are formed on the outer edges of the female member 18 and the female member 18, and annular grooves 21a, 21a that engage with the protrusions 14, 14 are provided on the inner surfaces of the flanges 21, 21 that face each other. Has been.

When assembling, for example, the male member 17 and the female member 18 are formed by
The bearings 13 and 13 of the sandwiching pieces 12 and 12 are arranged on both sides of the rotary shaft 12 so that they are loosely fitted to each other at intervals of 14 and 14 or more. Then, the connecting shaft 20 of the male member 17 is completely fitted into the through hole 19 of the female member 18. As a result, each protrusion 14, 14 is
The holding pieces 11 and 11 are engaged with the a and 21a, and are rotatably held with respect to the rotating shaft 12. As described above, the bite holder 10 holds the holding pieces 11 and 11 at the same time when the male member 17 and the female member 18 of the rotary shaft 12 are fitted together, and therefore the assembling workability is good. Further, since the sandwiching pieces 11 and 11 have the same shape, only one mold is required to inject them, which is advantageous in terms of cost. After that, attach a spring 22 of approximately U shape to each holding piece 11,1.
It is hung between 1 and urged so that the clamping parts 15 and 15 are closed. In this embodiment, each sandwiching piece 11, 11 is provided with windows 23, 23 along the length direction thereof, and
A guide groove 24 for accommodating the leg portion 22a of the spring 22 is continuously provided in the. Therefore, the legs 22a, 22a of the spring 22 are connected to the windows 23, 23
From the holding pieces 11 and 11 to the outside of the holding pieces 11 and 11 and placing the leg portions 22a and 22a in the guide grooves 24 and 24, the spring 22 is attached so as to straddle the holding pieces 11 and 11 (see FIG. 4). reference).

Referring again to FIG. 1, in order to attach the singing holder 10 to the table connection port 31a of the wind pipe 31 attached to the musical instrument body 30 of the keyboard harmonica, the holding pieces 11 and 11 are attached to the spring 22.
Open against, and the connection part 31a for the table play at the clamping parts 15,15
Just put it in. When the singing mouth 32 is not used, the singing mouth 32 itself or the root portion 31b of the wind instrument tube on the side of the singing mouth 32 may be placed so as to be sandwiched between the sandwiching pieces 11, 11. The sandwiching portion 16 can have various shapes,
For example, a sponge-like cushion material or the like may be provided at the same portion. Further, the holding surface of the holding portion 15 may be flat. Furthermore, since the mouthpiece holder 10 need only be pinched, it can be easily attached to, for example, a pipe leg of a performance stand.

[Effect of device]

As described above, according to the present invention, a versatile song port that can be applied not only to a wind pipe having a different diameter or a mounting position of a connection port for playing a table but also to a pipe leg of a performance stand, etc. Holder is provided.
