Description

Auxiliary keys for movable wind instruments

The invention relates to an auxiliary key of a wind-operated wind instrument, in particular to an auxiliary key which can be installed or removed under the pipe body of a wind instrument.

At present, low-cost plastic straight flutes on the market are generally used in educational fields. However, the fingers of the palms of oriental adults or school-age children are small, which causes the sound hole of some models of the flute to be too far away. The sound hole is difficult to press and cannot be pressed. Smooth performance or easy to cause tendon injury. Generally, wind instruments use auxiliary button mechanism to solve this problem, but the auxiliary parts of traditional wind instruments are directly drilled, locked or welded to the body of the wind instrument, except for the original instrument. The modification process will damage the body of the tube, and it is difficult for users to modify the existing musical instruments by themselves. Therefore, it is impossible to easily improve the problem of too far away from the hole.

Therefore, the present invention uses a pressing member with an auxiliary key mechanism, so that the user can easily add or remove auxiliary keys on the original wind instrument, and solve the problem of playing the sound hole too far without breaking the tube body. .

The foregoing and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the drawings.

As shown in FIG. 1, the first preferred embodiment of the auxiliary key of the movable wind instrument of the present invention includes a pressing member 2, which is composed of a hoop 21, a screw pressing end 211, and a limiting member 22; a button 1. The button 1 includes a button shaft 11, a gas-tight end 14, and a pressing point 15. The button shaft has a button limit end 12 for allowing the preload element 4 provided on the pressing member 2 to latch; the button 1 is provided on the rotating shaft support 23 of the pressing member 2 via the rotating shaft 3 axis.

As shown in FIG. 2, the pressing member 2 of the auxiliary key of the movable wind instrument of the present invention can be tightly arranged on the musical instrument tube body 5 by the hoop 21 and the screw pressing end 211, and the airtight end 14 on the key 1 is located at the sound hole of the instrument Above 51, the sound hole 51 of the instrument is interlocked when the player presses the pressing end 15 to rotate the key 1.

As shown in FIG. 3, when the player does not press 15, the button 1 is opened upward by the torque of the preload element 4 until the button limit end 12 comes into contact with the limit member 22, and then the sound hole 51 of the instrument is opened. The force element 4 may be a pogo pin, a spring, a magnet group, or the like.

As shown in FIG. 4, when the player presses 15, the key 1 rotates so that the airtight end 14 interlocks and presses the key sound hole 51. At this time, the instrument sound hole 51 is closed.

As shown in FIG. 5, the second preferred embodiment of the auxiliary key of the movable wind instrument of the present invention. The difference between this embodiment and the first embodiment is that only a single hoop 21 and a single shaft support 23 are needed to achieve the first A preferred embodiment has the same mechanical function.

However, the above are only the preferred embodiments of the present invention, which should not be used to limit the scope of the implementation of the present invention, that is, simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the description of the invention, All of them are still covered by the patent of the present invention.
