KR200300053Y1 - New type structure of Boehm system clarinet to transpose 10bis key and 11 key - Google Patents

Abstract

The present invention relates to a 10 bis keyboard and 11 keys of a clarinet.

(The clarinet has a variety of models and is equipped with the same or similar shapes as the 10bis and 11 keys, except for those made specifically differently.

Also, the 10 bis and 11 keys are called differently.

In this regard, only the names (10 bis and 11 keys) which are considered representative for convenience are described as representatives.)

The 10bis keyboard and the 11 keyboard installed in the conventional clarinet can express very small volume and can produce very delicate sound, but it is very difficult to use because the keyboard is located in a very uncomfortable place.

Therefore, the inventor devised and moved a new device to play these two keys more easily.

These keys are conventionally played with the second resin on the right, and the first resin on the right holds the musical instrument.

The tricky thing to play is that since the keys are located a little farther up from the right first resin, you have to stretch the right second resin and press the keys while holding the instrument with the right first resin. It takes time for the resins to be reduced in place and to have a stable posture.

These points are a significant limitation when playing.

The newly designed keys are moved to the upper left (the left side of the player when the player is holding the instrument), which is completely independent of the resin holding the instrument, and is played by tilting the side of the second resin on the left side slightly.

This is the case that the left second resin presses 10 keys and simultaneously presses 10bis or 11 keys. In this case, it has a great advantage that the sound produced by pressing two resins can be digested with one resin.

Description

New type structure of Boehm system clarinet to transpose 10bis key and 11 key}

The present invention relates to an apparatus of a keyboard in the structure of a clarinet clarinet.

It is related to two of the conventional clarinet keys (10 bis, 11), which are two side by side of the four keys protruding from the central left flank when the instrument is viewed from the front. (See Figure 1)

These keys are played by pressing the right second resin when playing.

These two keys are capable of expressing very small volumes and producing very delicate notes, but they are very difficult to use because the keys are located in an uncomfortable position when playing.

To press any of these two keys, rotate the right first resin holding the instrument, and at the same time, align the palms and the resin in a well aligned position (a stable preliminary posture that is not pressed but always ready to press). (2, 3, 4, 5 resin) is moved to the upper direction where the key is located while the second resin is extended to press the key.

At this point, your entire right hand will be in an unstable position, after which it will take some time to realign to play another note.

Furthermore, moving the right first resin holding the instrument may cause the instrument itself to shake, and if the mouthpiece part that has been finely adjusted is moved, the tone may be changed.

For these reasons, both of these keys can be burdensome to use, and the reason for the difficulty in playing is that the two keys are arranged in an inefficient space.

Therefore, the inventor devised and moved a new device to play these two keys with the left resin rather easily.

Detailed description of the newly designed 10 bis and 11 keys

17key-6brings Group B clarinet, the most widely used type of clarinet clarinet, is applied as a standard and will be described with drawings.

To achieve the above objectives, the 11 keys and 10bis keys were moved to the 10 keys by combining the physical functions of the instrument.

Specifically, first, the direction of the axis to configure the keyboard was set on the center line above the 10-key pad support of the instrument (see Fig. 3).

The reason for this is that, when the keys are pressed, it is judged that it is a point where the whole of the keyboard unit around the axis can be easily rotated.

The closer the key (between the center point of the axis shown in Figure 2 and the 11- or 10-bis key) is to the parallel line with the axis as the starting point, the more difficult it is to rotate the key and not to rotate when in contact.

The second reason for setting the axis to the center is that it is about the shape of the whole.

In FIG. 2, the 11 keys 101 and 10 bis keys 102 have an oval shape, and there is no difference from the shape of the keyboards (10bis, 11) that were used previously.

The 11 keys (101) and 10 bis keys (102) are located as shown in Figure 3, and the 11 keys (101) are slightly above the 10 bis keys (102), whose purpose is the left second resin shoulder. This is to facilitate pressing.

This is because the farther you are from the position of the 10 bis key 102, the more the left hand should be tilted.

The 11-key board 103 is attached to the 11-key pad support 105 and the 10-bis keyboard board 104 and the 10-bis keyboard pad support 106, respectively, and are integrally formed.

The keyboard bands from the axis to the keyboard are both curved as shown in the drawing, and then bent in parallel to the 10 bis and 11 keys.

This is just a form of intermediary that transmits power by pressing a key, so as long as there is no abnormality in motion (when any two keys are pressed, they will not touch the other keys, and when they are pressed, the rotation will be smooth). It is not limited even if it transforms to some extent.

It is a technical matter to be decided by the design of the person in charge.

The 11-key pad support 105 and the 10-bis key pad support 106 are the same in size and shape as before, as there is no change in the position or size of the existing holes (the holes corresponding to the sound of 10 bis, 11).

Naturally, the 11-key pad 107 and the 10 bis key pad 108 also use existing ones.

The 11-key operation stop pin 109 and the 10 bis operation stop pin 110 are for the purpose of stopping, and there is no difference from the usual practice.

The length (height) of these two pins will open the 11-key pad support (105) or 10-bis keyboard pad support (106) when the 11 keys (101) or 10 bis keys (102) are pressed during performance. When opened to the opened height of the keyboard pad support and the 10 bis keyboard pad support, the 11 key motion stop pin 109 and the 10 bis motion stop pin 110 are stopped at the point where the end is not rotated by touching the face of the instrument. Height.

Additional explanations will be omitted in this regard, and it is obvious to the person skilled in the art.

The 11-key operation stop pin cushion 111 and the 10-bis key operation stop pin cushion 112 are attached to the ends of the 11-key operation stop pin 109 and the 10 bis key operation stop pin 110, respectively.

These stop pins and cushions may be somewhat wider.

In addition, since the purpose is to stop, it can be installed anywhere in the lower part of the keyboard between the 11 keys (101) and 10 bis keys (102) from the shaft. This is a technical matter for the designer to decide on.

The 11 key spring hanger (113) and the 10 bis key spring hanger (114) are no different from the spring hangers used in the past.

The 11 key shaft support 201, the intermediate key support 202 of the 11 and 10 bis keys, and the 10 bis key shaft support 203 of the figure 2 are each screwed on the bottom of the instrument. After drilling, fix each support by rotating it.

The intermediate shaft support (202) of the 11 and 10 bis keys is located in the center of the 11 key shaft support (201) and the 10 bis key shaft support (203). Since the force of the spring is always applied to the body of the 10 bis keyboard stage 104, the bodies in the shaft interfere with each other physically. This is to prevent the interference phenomenon.

The position of the 10 bis key shaft support 203 is on the front centerline of the instrument as mentioned above and is installed directly above the pad rest of the 10 keys (see Figure 1).

Since it is installed here, the keyboard pad between the 10 bis keyboard pad 106 and the shaft is slightly curved when viewed from the front (see Fig. 3), and the instrument is tilted from the side (see Fig. 2) to follow the circle of the instrument. It has the same circular protrusions at some interval.

11 The keyboard pad between the keyboard pad 105 and the axis is in the form of a straight line when viewed from the front of the instrument (see Figure 3), while the instrument is tilted and viewed from the side (see Figure 2) at equal intervals along the circle of the instrument. It takes the form of a circular protrusion.

The 11-key shaft support (201), the 11-key and 10-bis key intermediate shaft support (202), etc., have a hole through which the axle screw can pass, and the 10-bis key support (203) is a nut I have a home.

In addition, there are 11 key spring fitting holes 204 and 10 bis key spring fitting holes 205 in the middle portion of the 11 key shaft support 203 and the middle portion of the 10 bis key shaft support 201, respectively. It can be inserted into the hole.

The 11 key springs 206 and 10 bis key springs 207 are straight springs that fit into the 11 key spring fitting holes 204 and 10 bis key spring fitting holes 205, respectively.

The axial screw 301 is a axial screw.

Through the above description, the technical idea of the present invention has been embodied, but the technical idea of the present invention is not limited thereto. In other words, it is possible for a person skilled in the art to variously modify the technical idea of the present invention within the technical scope of the claims.

Therefore, all modifications included in the claims will be included in the technical scope of the present invention.

As described above, the present invention plays the side of the left resin on the left side of the conventional method in which the right hand took time to play a different note after pressing a key (10 bis, or 11 keys) while playing. Compared with the conventional method, it is faster to switch to the preliminary motion after pressing the key, and also the stability of the sound can be ensured regardless of the movement of the hand supporting the instrument. By placing the keys of the keyboard near the 10 keys which have a great deal of connection with each other, the performance is enhanced.

More importantly, it is the key that plays the key that is the connection point between the Charlumo and the Clarion, among the three clarinet ranges (the low range is divided into the Challimo range and the mid range is divided into the Clarity range and the Altissimo range). This is a key that produces notes that correspond to the middle ranges used in music.

Thus, playing more smoothly than traditional keyboards, composers can write new ranges of music (using the 10 bis or 11 keys) and also expect players to play partial but more expressive music. do.
