is a balancing weight, 3 is a wire, 4 is a pulley, 5 is a wire stopper, 6 is a bar handle, 7 is a packing, 8 is a flag hinge, and 9 is a flag hinge attachment material. FIG. 1B is a schematic side view showing the panel in a closed state. FIG. 1C is a schematic front view showing the panel in a closed state. Figure 2A is a schematic top view of the panel body, where 1 is the frame, 2 is the wire through hole, and 3 is the panel side wing of the flag hinge. Figure 2 (b) is a schematic vertical cross-sectional view of the panel body, with 1 being a frame, 2 being a bottom plate, 3 being a sound insulating material, 4 being an air layer (filled with sound absorbing material to prevent resonance), and 5 being an air layer and sound absorbing material for selecting sound quality. Material, 6 is Patsuking. Figure 3A is a schematic side view showing the state in which the panel is closed when installed on an upright piano. 1 is the main body, 2
3 is a through bolt, 3 is a bearing, 4 is an endless rope, 5 is a pulley with a threaded hole that rotates with the endless rope, 6 is a caster, 7 is an inclined plate, and 8 is a packing. Figure 3B is a schematic diagram of the back of the panel body, where 1 is a pulley, 2 is a through bolt, and 3
is a guide pipe for endless rope, 4 is a pipe attachment saddle, and 5 is an endless rope.
FIG. 4 is a schematic vertical cross-sectional view of the panel main body, which is horizontal for a grand piano, but becomes vertical. 1 is a frame, 2 is a back plate, 3 is a sound insulating material, 4 is an air layer (filled with sound absorbing material to prevent resonance), 5 is an air layer and sound absorbing material for selecting sound quality, and 6 is packing.

Claims

[Scope of utility model registration request]

A method for producing a soundproof panel for a piano, which is characterized by being able to freely select the sound insulation effect and sound quality (sound absorption effect), and being able to be opened/closed and attached/detached with a single touch.
