However, the invention of Patent Document 1 has a problem that the method of attaching the device is complicated and the price of the device is expensive, so that a person who can use the device is limited.

In addition, since there is still a gap between the keyboard lid and the keyboard instrument body that occurs when opening and using the keyboard lid of a keyboard instrument such as a grand piano, the music score and writing instrument placed on the music stand are subject to slight vibration, There has been a problem that it is difficult to prevent falling into this gap.

The invention according to claim 1 comprises a main body portion made of a belt-like fabric, and at both ends of the main body portion, a keyboard lid locking portion for attaching to a tip corner portion of the keyboard lid, and the main body portion It is a cover for a keyboard cover of a grand piano in which an attachment string for fixing to the piano body is formed at both ends of the piano.

The invention of claim 2 comprises a bag-like part at the front edge of the main body part, a rubber string is attached to the inside of the bag-like part, and a bag-like part is constituted at the rear edge of the main body part, It is a cover for a keyboard cover of a grand piano in which a magnet is attached inside the bag-like portion.

According to the first aspect of the present invention, since the upper surface of the gap between the keyboard lid and the piano body, which is generated when the keyboard lid of the grand piano is opened, is covered over the entire surface, a musical score, a writing instrument, etc. are covered in the gap. It is prevented from falling.
Furthermore, since the keyboard cover is coupled and fixed to the piano body, it is possible to prevent damage to the grand piano and injury of fingers and the like due to sudden closing of the keyboard cover.

According to the invention of claim 2, since the rubber string is attached to the front edge of the main body, it can be attached while securely fitting to the surface of the keyboard cover, and a plurality of magnets are attached to the rear edge of the main body. Since the is attached, the main body can be easily and securely fixed to the piano body.

A first embodiment of the present invention will be described with reference to FIGS.
The cover 1 for the keyboard cover of the present embodiment constitutes a bag-like portion 5 by folding and sewing a main body portion 2 made of a substantially rectangular fabric and a front edge portion 21 of the main body portion 2 to the back side by about 1 cm. The rubber cord 6 is accommodated inside the bag-like portion 5, and both ends of the rubber cord 6 are fixed to the end portions of the main body portion 2 so that the rubber cord 6 penetrates the entire bag-like portion 5.
There is no limitation on the material and size of the main body 2, but a thin fabric with elasticity is preferable.
It can also be made solid by putting an interlining on the back.

The back edge 22 of the main body 2 is folded and stitched to the back side by about 2 cm to form a bag-like portion 3, and five magnets 4 are fixed inside the bag-like portion 3. The number of magnets is not limited to five and can be arbitrarily determined.

Furthermore, the short side part of the both ends of the main-body part 2 is extended about 4 cm from the edge part of the said bag-shaped part 5, respectively, and the extension part 2a is comprised at both ends. The extension portions 2 a and 2 a are folded to the back side, and the front edges 2 b and 2 b are sewn to the end of the bag-like portion 5.
As a result, a keyboard cover locking portion 2c having a part of a bag shape is formed on the back surface of the seam between the edge portion 2b in front of the extension portion 2a and the end portion of the bag-like portion 5.

Furthermore, one end of the attachment cord 7 is sewn on the rear side of the extension 2a at both ends of the main body 2. The attachment string 7 is for fixing the keyboard lid cover 1 attached to the keyboard lid 8 to the piano body 9.

The operation of the present embodiment configured as described above will be described.
When using the keyboard lid cover 1, first, the entire upper surface of the opened keyboard lid 8 is covered with the front portion of the main body 2 through which the rubber string 6 is passed.
At this time, as shown in FIG. 3, the keyboard lid locking portion 2c formed between the front edge portion 2b of the extension portion 2a at both ends of the main body portion 2 and the both end portions of the bag-like portion 5 is connected to the keyboard lid. 8 so as to be fitted into the tip corners 8a and 8a at both ends (see FIG. 5).

Thereafter, the attachment string 7 attached to the extension 2 a of the main body 2 is tied to the column 11 of the reverberation plate of the piano main body 9 and the magnet 4 is fixed to the surface of the internal metal plate 12.

Thus, the keyboard lid cover 1 is fixed to the entire upper surface of the keyboard lid 8 by the rubber string 6, the magnet 4 and the attachment string 7 and is securely attached to the piano body 9, so that the keyboard lid 8 is opened. There is no fear that the cover 1 for the keyboard lid will come off. Play the piano in this state.

Next, the effect of this embodiment will be described.
When playing or teaching the piano, a musical score or writing instrument is placed on the music stand 13.
In this case, in this embodiment, as shown in FIG. 5, the upper surface of the gap 14 between the piano body 9 and the keyboard lid 8 is entirely covered by the keyboard lid cover 1, so that vibrations and imperfections caused by playing are not caused. It is prevented that the musical score or writing instrument falls into the gap 14 due to caution, falls along the surface of the keyboard lid 8, and falls into the interior 9a of the piano.

Further, since the keyboard lid 8 is fixed to the piano body 9 by the keyboard lid cover 1, there is no risk of the keyboard lid 8 suddenly falling forward and closing, resulting in damage to the piano body 9 and keyboard lid. There is no risk of being injured with a finger between the fingers 8.
Further, the keyboard cover cover 1 is characterized in that it can be easily attached to and detached from the piano body 9 and is convenient for storage and form.
