[0025] For implementing the grand piano of the present invention, its outline and attached figure 1 The grand piano shown in . Thus, the grand piano has a piano case 20, which is similar to the piano case 1 in the prior art grand piano, and is also composed of side plates, keyways 21, upper beams 22, keyboard baffles 23, and cover plates 24. and other components assembled. The keyboard 25 is mounted on the keyway 21 at the rear of the keyboard bezel 23 and is partially inserted into the interior space of the piano case 20 through the groove between the side panel arm portions below the upper beam 22 . Although not shown in the drawings, action mechanisms, hammers, dampers and strings are accommodated in the inner space of the piano case 20, and the keyboard 25 is coupled with the action mechanisms so that the piano can be driven selectively. The mallet rotates freely. The strings collide with the respective hammers at their free-rotating ends. Accordingly, the grand piano ...

[0032] Refer to attached Figure 5 , shows a cover plate 31 that is present in another grand piano embodying the present invention. A grand piano embodying this second embodiment is similar in construction to that of the first embodiment, and accordingly, other parts are identified by reference numerals identifying corresponding parts in a grand piano embodying the first embodiment, where Not detailed.

[0033] The cover plate 31 has a relatively thick raised portion 31a, a relatively thin covering portion 31b, and a beak-shaped portion 31c. The shaft 31d is embedded in the relatively thick raised portion 31a, and protrudes laterally from the raised portion 31a. The shaft 31d is rotatably supported on a suitable bracket embedded in the arm portion of the side panel. The relatively thin covering portion 31b is fused into the relatively thick raised portion 31a. The relatively thin covering portion 31b has a substantially constant thickness, and a beak-shaped portion 31c pro...

Abstract

A grand piano, having a keyboard (25) placed on a keyway (21), and after practicing on the keyboard (25), the keyboard (25) is covered by a cover plate (24), wherein, the cover plate ( 24) is shaped in such a way that grooves (24e) can provide clearance for fingers placed on the black keys (12c) so that even if the pianist places his or her finger on the raised portion (12d) When her fingers are straightened before moving to other keys, the nails will never hit the inner surface of the cover plate (24).

Description

technical field [0001] The present invention relates to a keyboard musical instrument. In particular, the present invention relates to an acoustic piano or a musical instrument based on a piano having a keyboard covered by a fall board. Background technique [0002] Grand and upright pianos are the main forms of acoustic piano. Both grand pianos and upright pianos have traditional profiles, and users do not want to change the traditional profiles too much. figure 1 A typical grand piano is shown. The piano case 1 provides the grand piano with a unique profile. Three support legs 2 protrude downward from the piano case 1 so that the piano case 1 is positioned above the floor. The piano case 3 is suspended below the piano case 1 by means of the piano case support column 4, and the pedal 5 protrudes forward from the piano case 3. [0003] A side plate 6, an upper beam 7, a keyway 8, a flat plate 9, a top plate 10, and a cover plate 11 are assembled ...
