Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to the exterior structure of an electronic musical instrument, and particularly to the attachment structure of a mouthpiece to a shelf board in the exterior of a keyboard electronic musical instrument such as an electronic organ.

[Summary of the idea]

This idea involves fitting both ends of a channel-shaped opening rod made of a metal plate into the opening rod holders fixed to the opposing inner surfaces of the lower front ends of a pair of armrests, and attaching the ends to the front side of the shelf board. In the exterior structure of an electronic musical instrument with a mouth bar attached, a notch is formed at the bottom of each mouth bar holder into which the front end of the shelf board is loosely inserted, and the lower side of the mouth bar is placed along the notch and the front end surface of the shelf board. By bending the rod and extending it so that it overlaps the top surface of the shelf board, and screwing the extension part to the shelf board from the top surface, the end edge of the opening bar is not exposed to the outside, increasing safety. The opening rod can be easily and reliably attached with a small number of parts, and the appearance is not spoiled.

PRIOR ART

The exterior of a keyboard electronic musical instrument such as an electronic organ generally has a pair of side plates 1 on both the left and right sides and armrests 2 on the top, as shown in the side view in FIG. , a mouth bar 5, a top plate 6, a keyboard lid (not shown), etc. are provided, and a keyboard device 7 is mounted on the upper part of the shelf board 4 so as to be rotatable in the direction of the arrow.

In addition, the opening bar 5, which is attached to the front side of the shelf board 4 and exposed to the outside, is often formed in a channel shape from a metal plate with a wood grain pattern on the outer surface.

In that case, conventionally, as shown in FIG.
The lower side of the opening rod 5, which is formed into a substantially U-shaped cross section along the opening rod holder 8 fixed to the lower front end of the shelf with wood screws 9, is extended so as to overlap the lower surface of the shelf board 4. The extended portion 5a was attached to the shelf board 4 by screwing it from below with wood screws 10.

[Problem that the invention aims to solve]

However, in the exterior structure of such a conventional electronic musical instrument, the edge (cut edge) 5b of the mouthpiece 5 and the head of the wood screw 10 are exposed to the underside of the shelf board 4, that is, to the outside, so that the player There was a problem that there was a risk of injuring children's feet or catching clothes on them.

The purpose of this invention is to solve these conventional problems and improve the safety of electronic musical instruments, as well as to allow the mouthpiece to be installed easily and reliably with a small number of parts, without spoiling its appearance.

[Means for solving problems]

Therefore, in this invention, a shelf board is arranged between a pair of left and right arms to form a space for placing a keyboard, and a mouth bar holder is fixed to the opposing inner surface of the lower front end of each arm. , both ends of a mouth bar formed by a metal plate so as to be uniform in the width direction of the keyboard and having a substantially U-shape in cross section along the mouth bar holder are respectively fitted onto the mouth bar holder; In the exterior structure of an electronic musical instrument in which the mouth bar is attached to the front side of the shelf board, a notch is formed at the bottom of each of the mouth bar holders into which the front end of the shelf board is loosely inserted, and the lower side of the mouth bar is attached to the bottom of the shelf board. It is bent along the notch and the front end surface of the shelf board and extends so as to overlap the top surface of the shelf board, and the extended part is screwed to the shelf board from the top surface.

[Effect]

Since the edge of the mouthpiece and the head of the wood screw are not exposed to the outside, they do not touch the performer's feet or clothes.

In addition, since the bent part of the lower side of the opening rod is sandwiched between the notch of the opening rod holder and the front end of the shelf board that fits there, all you have to do is screw the extension part to the shelf board from the top at several points. Therefore, the mouth bar can be reliably attached to the arm and the shelf board, and since the screwed portion thereof is hidden by the keyboard placed on the upper part of the shelf board, the appearance is not spoiled.

〔Example〕

An embodiment of this invention will be described below with reference to FIGS. 1 and 2.

Figure 2 is a plan view showing the exterior shelf with the keyboard device removed, with the middle part omitted;
This is a sectional view taken along the line A-A in the figure, and the same parts as in FIGS. 3 and 4 are designated by the same reference numerals.

In this embodiment, the shelf board 4 is attached to the left and right arms 2 via splints 11. In addition, a pair of mouth bar holders 1 are provided inside the lower front end of each arm bar 2, 2.
8 and 18 are fixed with wood screws 9. As shown in FIG. 1, the opening rod holder 18 is formed with a notch 18a into which the front end of the shelf board 3 is loosely inserted.

The opening rod 15 is made of a metal plate, similar to the opening rod 5 of the conventional example described above, and is uniform in the width direction of the keyboard and has a substantially U-shaped cross section as shown in FIG. The lower side 15a is bent along the notch 18a of the opening rod and the front end surface of the shelf board 4 to form an extension part 15b extending so as to overlap the upper surface 4a of the shelf board 4.

Both end portions of this opening rod 15 are fitted onto and supported by opening rod holders 18, 18 fixed to the left and right arms 2, 2, respectively (see Fig. 2), and the extending portion 15b is attached to the upper surface 4a of the shelf board. They are stacked on top of each other with soft tape 12 interposed therebetween and fixed to the shelf board 4 from the top side (inside) using wood screws 10.

In this way, the edge 15c of the opening rod 15 and the head of the wood screw 10 are not exposed to the outside of the shelf board 4, so it is safe.

In addition, since the bent portion of the lower side 15a of the opening bar 15 for forming the extended portion 15b is sandwiched between the notch 18a of the opening bar holder 18 and the front end of the shelf board 4 fitted therein, The opening rod 15 can be reliably attached to the arm 2 and the shelf board 4 by simply screwing the installation part 15a at several places from the top surface to the shelf board 4 with wood screws 10.

Moreover, by rotating the keyboard device 7 upward as shown by the arrow in FIG.
Since the extension part 15a of 5 is exposed, screwing can be easily done from above, and by returning the keyboard device 7 to a horizontal position after installation, the screwing part is hidden by the keyboard. Because it is stored away, it does not spoil its appearance.

[Effect of idea]

As explained above, the exterior structure of the electronic musical instrument according to this invention prevents the edges of the mouthpiece and the heads of the wood screws that attach the mouthpiece to the shelf from being exposed on the underside of the shelf, so they do not expose the performer's feet or clothing. There is no risk of getting caught, increasing safety.

In addition, since the bent part of the lower side of the opening rod is sandwiched between the notch of the opening rod holder and the front end of the shelf board that fits there, all you have to do is screw the extension part to the shelf board from the top at several points. This makes it possible to securely attach the opening rod to the arm and shelf.

Further, since the screw-fastening portion is hidden by the keyboard placed on the upper part of the shelf board, the appearance is not spoiled.
