JPS5939741Y2 - Music stand locking device for keyboard instruments - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to an improvement of a music stand locking device.

In the conventional music stand locking device, when the music stand is stood up and the music sheet on it is played while playing, the music stand has a specific angle with respect to the clay roof of the keyboard instrument.

Therefore, due to the difference in the sitting height and posture of the performer, the angle of the line of sight of the performer and the score differs for each performer. Fatigue caused by difficulty in viewing the musical score due to an inappropriate angle of the stand becomes impossible to ignore.

Therefore, the purpose of this invention is to eliminate the above drawbacks,
Furthermore, it is provided for the purpose of preventing sideways shaking and unnecessary rotation of the music stand and also allowing the music stand to stand up with one touch. A supporting member 4 that rotatably supports the stand 3; and a guide member 8 that is arranged on the upper surface 5 of the clay roof of the keyboard instrument on both sides of the music stand 3 and has a lateral groove 6 and a plurality of lateral grooves 7 communicating with the lateral groove. The support member 4 is pivotally attached to the upper surface 5 of the clay roof of the keyboard instrument, and the protrusions 2, 2 are slidable within the grooves 6.7.

In the figure, reference numeral 4 denotes a support member made by deforming a round bar into a rectangular shape, the lower end 16 of which is pivoted to the upper surface 5 of the clay roof of the keyboard instrument by a first mounting member 9, and the upper end 10 of which is connected to a second mounting member. 11 is attached to the back surface of the music stand 3 and rotatably supports the music stand 3.

Reference numeral 8 denotes a guide member made of synthetic resin or the like, and as shown in FIG. A horizontal groove 6 having the shape of a shape is provided, and three inclined vertical grooves 7 are provided in the lower horizontal groove portion 12 in communication with the horizontal groove portion 12.

Thus, in order to raise the music stand 3 as shown in FIG. 1, first hold the upper part 13 of the music stand 3 in the laid down state shown by the two-dot chain line and move it in the direction of arrow A.

The movement in the direction of arrow A is caused by the end 15 of the horizontal groove portion 14 of the higher step.
The projection 2 of the music stand 3 located at is slid in the direction of arrow B.

When the music stand 3 is further moved in the direction of arrow A, the protrusion 2 enters the horizontal groove portion 12 of the lower step, and the three vertical grooves 7, 7.
7, the music stand 3 is inserted into a predetermined groove that can hold the music stand 3 at an angle that matches the sitting height and posture of the performer.

As a result, the music stand 3 can be raised to a position where the player can easily see it with a single touch.

Further, the movement of the protrusion 2 of the music stand 3 is limited within the horizontal grooves 6 and the vertical grooves 7.

Incidentally, in order to lower the music stand 3, the operation described above may be reversed.

As described above, according to the present invention, the upper surface 5 of the clay roof of the keyboard instrument
A support member for rotatably supporting the music stand 3 is pivotally attached to the music stand 3, and a guide member 8 having a horizontal groove 6 and a vertical groove 7 is provided adjacent to both sides of the music stand 3 on the side surface on the music stand 3 side. Since the protrusion 2 of No. 3 is slidably formed in both grooves 6 and 7, the standing angle of the music stand can be adjusted depending on the sitting height and posture of the performer, making it possible to perform while looking at the music for a long time. , the performer feels less physical fatigue, especially eye fatigue.

Furthermore, the music stand can be raised with a single touch, and it is possible to prevent the music stand from swaying sideways and the keyboard instrument from moving excessively in the front-rear direction.
