Claims

[Scope of utility model registration request]

On the underframe, the left and right side plates are connected by a horizontal bar, and the footrest plate, on which the auxiliary pedal is pivoted on the upper protrusion, crosses in an X shape when viewed from the side, and the intersection is pivoted with a pin. A bracket is provided on the bottom surface of the footrest plate by bending a banded iron plate into a circular shape, and a hollow space is provided that passes through the bottom of the bracket and the footrest plate so as to be vertically movable. A collar is fixed to the rod, and the hollow rod is brought into elastic contact with the lower surface of the stationary plate by a coil spring elastically mounted between the bottom of the bracket and the collar, and the lower surface of the auxiliary pedal is brought into contact with the upper end surface of the hollow rod. A U-shaped fitting part that is fitted from the side to a piano pedal is formed at the lower end of the insertion rod that is inserted into the axial center hole of the hollow rod from below, and the insertion rod is inserted into the lower end of the hollow rod. It is fixed with a long bolt screwed in from the rear, the lower front end of the X leg is pivotally connected to the underframe on the inside thereof, the upper front end of the X leg is pivotally attached to the lower surface of the stationary plate, and the rear end of the X leg is pivotally connected to the lower surface of the fixed plate. The lower end is fixed to a lower connecting rod whose both ends are supported inside the underframe so that it can move back and forth, and the rear upper end of the X leg supports the rear part of the footrest and is movable back and forth with respect to the footrest. An operating insert pin is pivotally attached to the end face of the upper connecting rod, extends forward from the rear edge of the footrest plate at the lower part of the footrest plate, and is screwed into a nut fixed to the upper connecting rod, and is rotatable in the inserter rod direction. An auxiliary pedal device for piano performance, characterized in that the auxiliary pedal device is immovably installed in the piano.
