Description

[Detailed Description of the Invention] The present invention relates to an expression pedal cover for an electronic organ.

Conventionally, this type of cover has been manufactured using, for example, an injection molding method to fix the lower front plate to the edges of both side walls a, a and rear wall b that cover the opening of the lower front plate of the electronic organ, as shown in the first figure. and ear piece cc for fixing the bottom plate,
d is integrally formed, but when installing this cover on the electronic organ or removing it for repairs, etc., three bolts must be screwed into the lower front plate and the bottom plate, and the cover must be removed. When attaching the cover, it must be placed at appropriate positions on the lower front plate and the bottom plate, which has the drawback of increasing man-hours and increasing costs.

The purpose of the present invention is to eliminate the drawbacks of such conventional covers, and a flexible flange plate 3 is integrally formed on the lower edge of the rear wall 2 of the cover body 1, which is shaped like a half-cut box. It is also characterized in that the flange plate 3 has a raised rib 4 for a hinge formed in a curved manner. To make the cover body 1 in the shape of a half-cut box, a plastic film or a plastic plate is placed in a mold, heated to an appropriate temperature and evacuated, and formed into a box shape as shown in the second figure. Cut along cutting line 5 to divide into two parts.

The flange plate 3 of the cover body 1 is as shown in FIG.
It is a fixed part fixed to the bottom plate 6 of the electronic organ,
A hole is made on the outer side of the raised strip 4 and it is attached with a screw.

In addition, if velvet type fasteners 7 are attached to the bottom surface at two locations as shown in FIG. 5, the cover body 1 can be fixed with the fasteners provided at the corresponding locations on the bottom plate 6. To fix the front part of the cover main body 1 to the lower front plate 8 of the electronic organ, use the cover fixing member 9 shown in FIG.
1 and 12 are engaged with the cover main body 1 and treated with adhesive if necessary, and the fixing piece 13 is fixed to the lower front plate 8 through the hole 14 with a screw 15. Note that the cover fixing member 9 can be molded integrally with the cover body 1.

In FIG. 6, 16 is an expression pedal, and a lead wire 17 of an electric component such as a variable resistor operated by this pedal 16 is connected to the cover body 1.
It can be accommodated inside the hinge ridge 4 through the hole and pulled out from the end through the hole in the back plate of the electronic organ.

Thus, when repairing the expression pedal, for example, remove the screw 15 and tighten the cover body 1 by 90 mm.
By tilting it backwards, the pedal part can be exposed without removing the screws that fixed the outer part of the raised strip 4.

As described above, according to the present invention, the flexible flange plate 3 is integrally formed on the lower edge of the rear wall 2 of the cover body 1, and the raised rib 4 for the hinge is formed in a curved manner on the flange plate 3. , the number of man-hours required for attaching and removing the cover to and from the electronic organ is reduced, which has the effect of lowering costs.
