JPS5918463Y2 - Music stand device for keyboard instruments - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a music stand device for a keyboard instrument.

Conventionally, in this type of device, the lower end of the music stand is rotatably attached to the upper surface of the roof board of a keyboard instrument, and when the music stand is erected, a support member rotatably attached to the music stand is erected, and the lower end of the music stand is There is a known type that retains the upright position by locking it with a stopper.

According to such conventional music stand devices, when standing up, the lower end of the supporting member must be locked to the stopper after the music stand is erected, which is time-consuming and requires a lot of effort, and the stopper is located at the top of the keyboard instrument shed. Since it needs to be mounted independently on the top surface of the board, there are drawbacks such as an additional number of parts and man-hours.

Furthermore, since the depth of a keyboard instrument cannot be reduced below the sum of the distance between the music frame and the bottom of the music stand, the height of the music stand, and the length of the keyboard, it is possible to reduce the depth of the keyboard instrument by technological advances in the internal parts of the keyboard instrument. Despite higher density and smaller size, it has been difficult to reduce the external dimensions, especially the depth dimension.

Therefore, the present invention has developed a music stand device that eliminates these drawbacks, eliminates the need for a separately installed stopper, and makes the depth of the keyboard instrument approximately equal to the sum of the height of the music stand and the length of the keyboard. The lower end 2 of the support member 1 is pivotally connected to the upper surface 3 of the roof board of a keyboard instrument, and a music stand 4 is rotatably attached to the upper end, and the music stand 4 is attached to the lower end edge 5 of the supporting member 1. It is characterized in that it can be held in an upright state by the support member 1 and the support member 1.

Next, one embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in Fig. 1 and Fig. 2, the upper surface 3 of the roof board of the keyboard instrument
The lower ends 2, 2 of the two supporting members 1, 1 are connected to the locking members 6, respectively.
, 6, and are rotatably mounted around a fulcrum A.

Furthermore, a music stand 4 is attached to the upper end of each support member 1, 1 so as to be rotatable about a fulcrum B by locking members 7, 7, respectively, and the lower edge 5 and two support members of a predetermined length are attached to each other. 1,1
This keeps the music stand in an upright position.

At this time, the music stand 4 tends to fall backward due to the moment in the C direction caused by the gravity of the music stand 4, but since the support members 1, 1 are attached to the inside front of the music stand 4, the support member 4 is centered around the fulcrum B. Rotation in the F direction about the fulcrum A is prevented by the lower edge 5 of the music stand 4.

Further, as shown in FIG. 3, notches are formed in some of the locking members 6, 6 to prevent the music stand 4 from falling toward the front side of the keyboard instrument.

On the other hand, when laying down the music stand 4, rotate the music stand 4 in the direction of the arrow around the fulcrum A so that the lower edge 5 of the rear side 4-a of the music stand 4 is aligned with the upper surface 3 of the roof board of the keyboard instrument. , and tilt the music stand forward to a position where the front lower edge 9 can rotate in the direction of the arrow C around the fulcrum B, and then rotate the music stand in the direction of the arrow around the fulcrum B until it reaches the position shown by the dotted line. Lay down in position.

Note that a stay or the like may be used as the support member 1, and the mounting structure thereof may be provided by providing a groove in the music stand 4, and is not limited to the above embodiment as long as the above object is achieved. do not have.

Further, a cushioning material for preventing scratches may be provided at a portion where the lower edge 5 of the rear side 4-a of the music stand 4 contacts the upper surface 3 of the roof board of the keyboard instrument when the music stand 4 is erected.

If you want to stand up from a collapsed state, it is best to perform the reverse operation as described above.

In this way, according to the present invention, the lower end 2 of the support member 1 is pivotally connected to the upper surface 3 of the roof board of the keyboard instrument, and the music stand 4 is rotatably attached to the upper end thereof, and the music stand 4 is attached to the lower end edge 5 of the supporting member 1. Since it can be held in an upright state by the support member 1 and the support member 1, there is no need for a stopper like in the conventional example, and
You can operate the music stand with one hand and with just one touch.

Furthermore, the depth dimension of the keyboard instrument excluding the length of the keyboard can be set to approximately the height of the music stand, so the depth dimension of the keyboard instrument is reduced compared to the conventional example, and the structural materials of the keyboard instrument can be saved. ,
It is possible to provide a keyboard instrument at a low cost, and furthermore, even in consideration of recent housing conditions, there are effects such as the ability to effectively utilize a narrow space.
