Description

[Detailed description of the invention] This invention can be easily assembled and connected to a support or back mechanism by omitting shelf supports and end bases, and also allows for easy assembly and connection of keyboard reeds and
The present invention relates to a metal member for the exterior of a piano, on which a keyboard, an action, etc. can be placed, a main plate, an arm, etc., which can be assembled and connected with high accuracy and easily.

For example, in the conventional assembly of the exterior of an upright piano, for example, as shown in FIG. Then, as shown in Figure 2, the parent plates 7, 7 (normally the arms 8, 8 are attached to the parent plates 7, 7 in advance).
After assembling and connecting to this back mechanism 1, the shelf board 9, shelf supports 10, 10, and end bases 11, 11 are assembled and combined, and then the keyboard reed, keyboard, and action part (not shown) are assembled. That's what I was doing. Therefore, each string 6 stretched on the frame 5 disposed on the support 2
Since various assembly and connection errors are concentrated between the action part placed on the shelf board 9 and the action part placed on the shelf board 9, a considerable amount of adjustment is required to obtain the correct hitting point of the string 6 in the action. It required a lot of man-hours and skill.

This invention was made in view of the above-mentioned drawbacks, and consists of an upper horizontal piece that serves as a shelf bracket on which the keyboard reed, keyboard, and action components are placed, one end of which is connected to a support or back mechanism; A front vertical piece that hangs down from the other end of the horizontal piece and serves as a shelf support post, and a front vertical piece that extends rearward from the other end of the front vertical piece in substantially parallel to the upper horizontal piece, the other end of which is a support or back mechanism. By using a piano exterior metal member consisting of a lower horizontal piece that is joined to the lower part and serves as the end base, the shelf supports and end base can be omitted, and it can be easily assembled and connected to the support or back mechanism. To provide a metal member for the exterior of a piano, in which a keyboard reed, a keyboard, an action, etc. can be placed, a main board, an arm, etc. can be assembled and connected with high accuracy and easily.

Hereinafter, one embodiment of the piano exterior metal member according to this invention will be described in detail with reference to the drawings.

FIG. 3 is a perspective view showing an embodiment of the piano exterior metal member according to this invention, in which the metal member 12
is one end (mounting part) 12a strut 2 or back mechanism 1
An upper horizontal piece 12b is provided to connect the keyboard reed, the keyboard, and the action components, and a front vertical piece 12c that hangs down from the other end of this upper horizontal piece 12b and serves as a shelf support pillar. A lower horizontal piece that extends rearward from the other end substantially parallel to the upper horizontal piece 12b, and is provided so that the other end 12e is assembled and connected to the lower part of the support column 2 or the back mechanism 1, and serves as an end base. 12d.

FIG. 4 is a perspective view showing another embodiment of the piano exterior metal member 12 according to this invention, showing an upper horizontal piece 12b, a front vertical piece 12c, and a lower horizontal piece 12.
d and a rear vertical piece 12f that becomes the attachment part to the support column 2 or back mechanism 1 (the upper end of this rear vertical piece 12f is joined to one end 12a of the upper horizontal piece 12b, and the lower end is joined to the lower horizontal piece 12d). It consists of

FIG. 5 is a perspective view showing an example in which the piano exterior metal member 12 of this invention shown in FIG. A shelf board 9 is arranged on the exterior metal members 12. After that, by arranging the keyboard reed, keyboard, and action with the upper surface of this shelf board 9 as a reference, and by assembling and connecting the outer case members such as the main board and arm, the normal hitting of the action and the strings can be easily and accurately performed. It is possible to obtain a connection with a point, and it is also possible to easily assemble and connect the main plate and the arm. The method of attaching the piano exterior metal member 12 and the back mechanism 1 or support column 2 is shown in FIG. 6A.
As shown in FIG. 1, a notch 13 is provided in the side surface of the back mechanism 1, that is, the support 2, the beating part, and the soundboard, and one end (attachment part) 12a of the piano exterior metal member 12 is connected to this notch 13, As shown in FIG. 6B, this is done by a structure in which one end (attachment part) 12a of the piano exterior metal member 12 is connected to the front surface of the back mechanism 1, that is, the soundboard 4 and the beater.
In this case, one end (attachment part) 12a of the piano exterior metal member 12 and the upper horizontal piece 12b are reinforced with 12 g.
It is convenient to provide. Although not shown, as another example, the metal member 12 is directly attached to the back mechanism 1 without notching the side surface of the back mechanism 1, and instead, the main plate is attached to the side surface of the back mechanism 1. 7 and arm 8 may be provided with notches.

In addition, the upper horizontal piece 12b, the front vertical piece 12c,
Although the lower horizontal piece 12d is illustrated as being in the form of a flat plate, it goes without saying that a part or all of it may be formed into a square pipe, a round pipe, an angle, a channel, etc.

As described above, the piano exterior metal member of this invention has a simple structure, can omit shelf supports and end bases, and can also be used for shelves, keyboard reeds, keys, actions, main boards, etc. The assembly and connection of the arms can be easily performed with high accuracy and is effective.
