Description

[Detailed explanation of the invention] (Industrial application field) This invention can be easily installed on a grand piano,
This invention relates to an auxiliary music stand device for a grand piano that is removable and whose inclination angle can be adjusted.

(Prior Art) Conventionally, the music stand of a grand piano is provided on the top surface of the piano body, and is located at a higher position than that of an upright piano. That is, it is set on the premise that it will be used by normal adults. For this reason, when short infants, children, etc. try to play, the musical score is located above their eyes, and they must always play with their heads upwards, forcing them into a cramped playing position.

It is also inconvenient for people with poor eyesight.

Furthermore, when performing at night, etc., the roof panels are closed to prevent noise from surrounding the area.
There was the inconvenience of not being able to use the music stand.

Therefore, as a means to solve this problem, an auxiliary music stand as shown in FIG. 5 has been proposed.

That is, a connecting rod B is rotatably supported on a heavy support frame A on the upper surface of the piano top plate F, and this connecting rod B is
A music board D is rotatably provided at the tip of the piano via a connecting part C connected by a pin structure, and a step-like projection E is configured to engage with the front end of the piano top board F at the bottom of the back surface of the music board D. ing.

(Problems to be solved by the invention) In the structure shown in FIG. 5, the support frame A is simply placed on the piano body, and the music board D is engaged with the front end of the piano top board F. The stability was poor, and the music board D could easily come off if you caught your finger on it when turning the music, and if you placed something heavy like an etude collection on it, the weight would cause it to fall forward. .

Moreover, this structure has the biggest drawback that it cannot be used with the top plate F of the piano open, since it is intended to be used with the top plate F of the piano closed.

This invention aims to improve the above-mentioned drawbacks.

(Means for Solving the Problems) This invention consists of a support member 2 having a downward elongated groove 3 at the rear end, a support member 2 rotatably supporting a receiving metal fitting 6 at the front end, and a plurality of support members 2 on the back surface. It consists of an auxiliary music stand 7 to which a pair of latch fittings 9 having a locking groove 8 are attached,
The support member 2 is supported by inserting the groove 3 into the front stile 10 of the piano body, and the locking groove 8 of the latch fitting 9 is inserted into the receiving metal fitting 6 to removably lock the auxiliary music stand 7 and tilt it. The angle is adjustable.

(Function) Since the groove of the support member is inserted and locked into the front stile of the piano body, it is stable and easy to attach and detach, and the angle of the auxiliary music stand can be adjusted.

(Example) An embodiment of this invention will be described below.

FIG. 1 is a sectional view showing a state in which the auxiliary music stand device according to this invention is attached, and the support member 2 is made of metal or synthetic resin, and is formed at the rear end to be slightly wider than the front stile 10 of the piano body 1. A downwardly extending groove 3 that is long in the left and right direction is provided, and the inner hanging piece 3a of this groove 3 is formed longer than the other piece 3b.

Further, as shown in FIG. 2, bent portions 4 bent upward are provided on both sides of the front end of the support member 2. As shown in FIG. A receiving metal fitting 6 rotatably supported by a screw 5 is spanned over this bent portion 4 .

On the other hand, as shown in FIG. 3, a pair of latch fittings 9 are attached to the back surface of the auxiliary music stand 7, each having a plurality of grooves 8 arranged vertically at a predetermined interval into which the receiving metal fittings 6 are fitted. This groove 8 is formed to be equal to or slightly deeper than the width of the receiving metal fitting 6, and is formed to be somewhat wider than the thickness of the receiving metal fitting 6.

When using the auxiliary music stand 7 constructed as described above, first open the front roof 11 and open the groove 3 of the support member 2.
is inserted onto the front stile 10 and locked. Although the locked support member 2 tries to rotate forward due to its own weight, the hanging piece 3a of the groove 3 comes into contact with the front surface of the front stile 10 and stably supports the support member 2.

As shown in FIG. 4, the auxiliary music stand 7 is attached by inserting the groove 8 of the latch 9 on the back side into the receiving metal 6 which is pivotally supported on the support member 2 at a desired height.

Also, when the front roof 11 of the piano body 1 is closed,
The upper end rod 12 of this front roof 11 is connected to the groove 3 of the support member 2.
Since the support member 2 is pressed against the upper surface of the front stile 10, the support member 2 is held more stably and reliably.

The inclination angle of the auxiliary music stand 7 can be adjusted by tilting the auxiliary music stand 7 to a desired angle and then adjusting the screw 5 that pivotally supports the receiving metal fitting 6.

Note that the auxiliary music stand 7 must be installed in advance.
The support member 2 may be inserted and locked onto the front stile 10 after the latch fitting 9 is attached to the receiving metal fitting 6 of the support member 2.

(Effects) As described above, according to the present invention, the auxiliary music stand can be held stably and reliably by simply inserting and locking the groove of the support member into the upper surface of the front stile of the piano body. Furthermore, since the auxiliary music stand can adjust its inclination angle in its installed state, it has the advantage of being variable depending on the user's line of sight. Furthermore, if the auxiliary music stand is not needed, it can be easily attached and removed, and the music stand on the piano itself can be erected even with the support member in place, so if an adult uses the piano after it has been used by an infant, etc. It also has the advantage of making it easier to play the piano by removing only the auxiliary music stand.
