JPS5924073Y2 - A device for releasing performance sound on a vertical piano - Google Patents

Description

[Detailed Description of the Invention] This invention relates to an opening device for a vertical piano, which allows performance sounds that tend to be trapped inside the instrument body to be emitted directly to the outside.

When a grand piano is played, the roof plate is wide open upwards so that the sound of the performance can be transmitted to the outside, but even if the roof of a vertical piano can be opened and closed, it is generally used as a stand for decorations, sheet music, etc. It is used as a piano, and it is troublesome to open the roof each time a piano is played, and since it is normally played in a closed state, compared to a grand piano, the player (especially harmonic sounds that are easily absorbed) is trapped inside the piano. There are certain drawbacks.

Therefore, this invention attempts to solve the above-mentioned drawbacks by making a part of the flat roof openable and closable.

To explain the embodiment with reference to the drawings, A in Fig. 1 is the main body of the piano.
A flat roof 1 is erected on top so that the hooks are crossed, and this flat roof 1 is divided into two in the longitudinal direction, with the front part 1a
is rotatably hinged to the rear part 1b.

In addition, at the center of the surface of the upper front plate 3, there are 1
A pair of bearings 4 are mounted vertically, and cushioning material 5 such as felt is pasted on both lower sides.

Reference numeral 6 denotes a music stand of a required size in the form of a slanted side, with an appropriate cushioning material on the bottom surface, and bearings 7 mounted horizontally on both upper sides of the back surface. Front plate 3
An inverted pin 8 is inserted into the upper bearing 4 in a crossed manner, and the music stand 6 is attached to the front surface of the front plate 3 so that it can be tilted and moved up and down slightly with respect to the piano body A.

FIG. 2 shows the piano when it is not in use, with the front portion 1a of the flat roof 1 closed and the music stand 6 held in an upright position with its lower end resting on top of the front portion 1a.

Therefore, when performing, the music stand 6 is lifted upward, the front part 1a of the flat roof 1 is rotated upward, and its upper end is placed against the cushioning material 5 on the upper front plate 3, and the music stand 6 is rotated upward. When the front matter is placed on the wood 9, the music stand 6 will be tilted at an appropriate angle as a music rest, as shown in Figure 3, and the interior of the piano body A will have a flat roof. It communicates with the outside through an opening in the front portion 1a of the device.

Therefore, if the player plays in this state, the sound will be transmitted directly to the outside without being trapped inside the piano body.

Then, at the end of the performance, the music stand 6 is lifted again, the front part 1a of the flat roof 1 is closed, the music stand 6 is lowered, and the lower end is rotated rearward to return to the initial state shown in FIG. 2.

As mentioned above, in this invention, the flat roof is divided into a front part and a rear part in the longitudinal direction, the front part is attached to the rear part so as to be freely rotatable, and the music stand is attached to the front of the upper front plate so that it can be moved up and down and tilted freely. Therefore, when playing, the front part of the lower roof can be easily opened, allowing the inside of the piano body to communicate with the outside, and the playing sound being transmitted directly to the outside without being trapped inside, providing the same performance effect as a grand piano. Can be done.

[Brief explanation of the drawing]

The drawings show an embodiment of this invention, and FIG. 1 is a perspective view of the music stand separated from the piano body. FIG. 2 is a partial side view showing a state in which the lower roof is closed with the side panels removed. FIG. 3 is a partial side view showing a state in which the front part of the lower roof is opened with the side panels removed. FIG. 4 is a perspective view of a portion of the piano body in the same state. In the figure, A is the main body of the piano, 1 is the lower roof, 1a is the front part,
1b is the rear part, 2 is the armrest, 3 is the upper front plate, 4.7 is the bearing, 5 is the cushioning material, 6 is the music stand, and 8 is the pin.
