Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting structure for an expression pedal of an electronic musical instrument such as an electronic organ.

Conventional expression devices for electronic musical instruments are
As shown in FIGS. 1, 2, and 3, an opening c is provided in the lower front plate b of the musical instrument body a, and a bottom plate d is fixed to the lower edge of the opening c on the back surface of the lower front plate b, This bottom plate d
Expression pedal e was screwed to the top, and cover f was screwed from the back side.

However, with this one, it is difficult to locate the expression pedal e, and the workability is poor because it has to be fixed in a narrow place.Furthermore, since the cover f is attached from the back side, the expression pedal e
It is difficult to position the cover f against the Furthermore, the opening c of the lower front plate b has a wood end that protrudes, so it has to be painted, and as shown in Figure 4, a window frame g must be attached and the wood end must be treated.

The purpose of the present invention is to eliminate the drawbacks of the conventional example, and a window frame flange 1 is attached to the edge of the opening.
A pair of L-shaped protrusions 8, 8 and a fitting hole 11 are provided inside the lower side plate 2, and the left and right side plates 12,1
The expression pedal 3 is comprised of a box 4 having a mounting claw 13 on the outside thereof, and an expression pedal 3 pivoted to a base 9 having a protrusion 10 and a locking claw 19. The base 9 is fitted between the protrusions 8, 8, and the protrusion 10 and locking claw 19 of the base 9 are inserted into the fitting hole 11 of the lower side plate 2 and the L-shaped protrusion 8.
Lock the expression pedals 3 and 3.
The lower front plate 6 of the instrument body 5 is fixed to the case 4.
The window frame flange 1 and the mounting claw 13 are used to fix the window frame flange 1 to the edge of the opening 7.

In FIG. 5, the box 4 is provided with window frame flanges 1 on the left and right sides of the opening edge and at the bottom, and has a lower side plate 2 provided with an L for fixing the expression pedal 3.
Formed protrusions 8, 8 are provided on the left and right, and a hole 11 for fitting a protrusion 10 provided on the lower surface of the base 9 of the expression pedal 3 is provided in front of the protrusion 8, and is attached to the upper and lower sides of the left and right side plates 12, 12. Attach the cord 1 of the expression pedal 3 to the bottom plate 14.
5 and an outlet 17 for the connector 16 were provided, respectively. Furthermore, as shown in Fig. 5, the fixing flange 1
8 is even better in terms of strength. A locking pawl 19 is provided on the base 9 of the expression pedal 3 on the upper side opposite to the projection 10.

Thus, first, the expression pedal 3 is inserted into the lower side plate 2 of the case 4, and the claw 19 of the base 9 is engaged with the L-shaped protrusion 8, as shown in FIGS. is engaged with the fitting hole 11 of the case 4 to fix the expression pedal 3 to the lower side plate 2 of the case 4. At this time, the cord 15 and connector 16 are pulled out from the outlet 17. Then the seventh
As shown, the opening 7 of the lower front plate 6 of the instrument body 5
Then, insert the case 4 until the window frame flange 1 is in contact with the lower front plate 6 surface and the mounting claw 13 is locked to the back side of the lower front plate 6, and if necessary, tighten the flange 18 with the screws 2.
0 to fix it to the bottom plate 21.

In this way, according to the present invention, the case 4, which has the window frame flange 1 on the edge of the opening and has the expression pedal 3 fixed at a predetermined position on the lower side plate 2 in the above-described configuration, is attached to the main body of the musical instrument. 5 lower front plate 6
Since the case 4 is fitted into the opening 7 of the instrument body 5 and fixed to the edge of the opening 7 by the window frame flange 1 and the mounting claw 13, the expression pedal can be connected by simply fitting the case 4 into the instrument body 5 from the front. 3 to the instrument body 5, the end treatment of the opening 7, and the cover installation can be done all at once, and there is no need to position the expression pedal 3 and the cover, resulting in good workability. .
