Problems solved by technology

However, if this known auxiliary pedal system is firmly connected to the pedal 5A / 5B / 5C, its complicated assembly and disassembly work will consume his or her patience for screwing
[0011] Another problem is that this prior art auxiliary pedal system detracts from the appearance of an acoustic piano, and users may prefer an electronic keyboard with a funky look

no. 3 example

[0052] Figure 7 Another pedal system 48 used in the grand piano 3 of the present invention is shown. A keyboard 3a, a mechanical structure 3b, hammers 3c, dampers 3f and strings 3d are housed in the piano case 3e. When the cover plate constituting a part of the case 3e is lifted, the keyboard 3a is exposed to the player. The mechanical structure 3b, the hammer 3c and the strings 3d are well known to those skilled in the art, so no further description will be given below.

[0053] The pedal system 48 has a pedal base 12 , a pedal box 49 , three pedals 15 , a link mechanism 50 and a flexible wire 51 . The pedal base 12 and the three pedals 15 are similar to those of the grand piano of the first embodiment, so the description will focus on the other components.

[0054] The pedal box 49 has a shape of a rectangular parallelepiped, and upper / lower panels, front / rear panels and side panels defining an inner space. Three pedals 15 are rotatably supported in the defined interior...

[0064] see Figure 9 , the pedal system 61 is used in another embodiment of the grand piano of the present invention. The pedal system 61 has a pedal base 12a, a pedal box 49a, three pedals 15, flexible wires 51 and a link mechanism 62. The three pedals 15 and the flexible wire 51 are similar to those of the third embodiment, so they will not be described in detail below.

[0065] The pedal base 12 is also fixed to the lower surface of the key base not shown, and is formed with a guide groove 63 . The groove 63 extends laterally and opens on the side of the pedal base 12a. Guide slots 64 also extend laterally and are formed in the side panels of the pedal box 49a. Two pairs of linkages 53A / 53B and a central screw 66 together with screws 54 / 55 make up the linkage. Links 53A respectively cross over cooperating links 53B and connect them with a central screw 66 . The central screw 66 adjusts the connecting rod 53A / 53B to a certain included angle. However, when the central s...

Abstract

A large piano has a pedal system (10), which consists of a pedal base (12) connected to the lower surface of the piano case (11), a pedal column (13) suspended from the pedal base (12), and a pedal column ( 13) A pedal box (14) connected, the pedal (15A / 15B / 15C) supported in a rotatable manner by the pedal box (14) and the pedal (15A / 15B / 15C) and the damping mechanism / keyboard (3f / 3a) is composed of pedal rods (16) connected to each other. When placed in the piano case (3e), the pedal box (14) can move along the pedal column (13). Between the pedal box (14) and the pedal column Between (13) configure coupler (23 / 25) to keep pedal on the suitable position to the player. Thereby the player can adjust the pedal to a suitable position before playing with the keyboard.

Description

technical field [0001] The invention relates to a keyboard musical instrument, in particular to a keyboard musical instrument such as an acoustic piano and a combined keyboard instrument made on the basis of the acoustic piano. Background technique [0002] Figure 1 shows a typical example of an acoustic piano. This acoustic piano is called a grand piano. The prior art grand piano includes a piano case 1 , legs 2 and a pedal system 3 . Although a keyboard, mechanism, hammers, dampers and strings are mounted within the hood, these components are not visible in this figure. Legs 2 protrude downward from the piano body 1 and support the piano body, and thus the constituent members, on the floor. [0003] The pedal system 3 works in conjunction with the dampers and the keyboard. When the player actuates the pedal system 3, the pedal system 3 separates one or several dampers from the strings and causes the keyboard, and thus also the hammer pins, to sl...
