본 고안은 피아노 연주시 사용하는 페달 안내공을 개폐하는 장치에 관한 것이다.The present invention relates to a device for opening and closing the pedal guide hole used when playing the piano.

종래의 피아노는 페달안내공이 개방되어 있어서 피아노 연주를 하지 않고 주위에 사람이 없을때 페달안내공을 통해 생쥐와 같은 작은 동물이 피아노 내부에 들어가서 부품을 손상시키기 때무에 학교나 교회강단에 설치된 피아노의 경우 피아노 연주가 끝나면 관리인이 페달안내공을 하나하나 막아주고 연주시는 다시 열어 놓아야 하는 등의 방법을 취하고 있으나 상당히 불편하고 일손도 많이드는 결점이 있었다.Conventional pianos have a pedal guide that is open, and when there is no person around, the pedal guides a small animal such as a mouse to enter the piano and damage parts. When the piano is finished, the manager takes a pedal guide and stops one by one, and when you play, such as taking a way to open, but it was quite uncomfortable and laborious drawback.

본 고안은 위와같은 종래의 불편을 시정하기 위하여 피아노 페달안내공 외측면에 밀착하여 승강되게 개폐판을 장치하므로서, 피아노 연주를 위해 페달의 발판을 밟으면 개폐판이 하강되고 페달 발판에서 압력을 해제하면 개폐판이 일정위치로 상승하여 페달안내공을 즉시 폐쇄할 수 있게 만들어 생쥐와 같은 작동 동물이 피아노 내부에 들어가지 못하게 구성한 것인데 이를 보다 상세히 도면에 의거 설명하면 다음과 같다.The present invention is to close and close the piano pedal guide ball in order to correct the conventional inconvenience as described above, so that the opening and closing plate is raised and lowered, when you step on the pedal foot for the piano playing, the opening and closing plate is lowered and the pressure is released from the pedal foot opening and closing The plate rises to a certain position so that the pedal guide ball can be immediately closed, so that a working animal such as a mouse is not configured to enter the piano, which will be described in detail with reference to the accompanying drawings.

피아노 본체(1)의 페달(2) 설치부에 형성되는 페달안내공(3)의 양측 외면에 수직안내홈(6)(6a)이 형성된 개폐막 장치구(4)(4a)를 취부편(5)과 보울트(5a)를 통해 고정시키고 양측 개폐판 장치구(4)(4a)의 수직안내공(6)(6a)에 안내되면서 페달안내공(3) 외측면에 밀착되어 승강되도록 개폐판(7)을 횡성시켜 개폐판의 상단이 페달(2) 저면에 접촉되게 하고 개폐판(7)과 개폐판 장치구의 고정돌기(8)(8a) 사이에 코일스프링(9)(9a)을 장진하여서된 구조이다.The opening and closing membrane device holes 4 and 4a in which the vertical guide grooves 6 and 6a are formed on both outer surfaces of the pedal guide hole 3 formed on the pedal 2 mounting portion of the piano main body 1 are mounted pieces ( 5) and through the bolt (5a) and guided to the vertical guide hole (6) (6a) of the opening and closing plate device (4) (4a) on both sides of the opening and closing plate to be in close contact with the outer surface of the pedal guide hole (3) (7) sideways so that the upper end of the open / close board is in contact with the bottom of the pedal (2), and the coil springs (9) and (9a) are held between the open / close board (7) and the fixing protrusions (8) (8a) of the open / close board mechanism. It is a structure.

이와같이된 본 고안은 페달안내공(3) 전면에 개폐판(17)이 밀착되게 횡설되어 피아노 본체에 형성된 페달안내공 입구를 막으면서 상단은 페달(2)의 저면에 밀착되므로 연주를 하지 않을때는 개폐판이 상승하여 페달안내공 입구를 막아주게 되고 연주시 페달을 밟으면 페달과 같이 개폐판(7)이 하강되므로 페달작동이 가능하여 연주에 장애가 없게 되며 연주가 끝나서 페달에 압력이 해제되면 코일스프링(9)의 탄력으로 개폐판(7)이 상승하여 페달안내공(3) 입구를 막아 틈을 폐쇄하도록 되기 때문에 생쥐와 같은 작은 동물이 페달안내공(3)으로 들어갈 수 없도록 되고 개폐판 고정구(4)(4a)의 수직안내공(6)(6a)으로 인해 개폐판(7)이 페달 안내공(3)의 표면에 밀착되어서 승강되도록 개폐판을 설치할 수 있어 정밀하며 어느 피아노든지 간편한 작업으로 개폐판을 시설할 수 있으므로 실용화가 용이한 장점이 있는 것이다.The present invention as described above is closed so that the opening and closing plate 17 is in close contact with the front of the pedal guide hole (3) to block the entrance of the pedal guide hole formed on the piano body, the top is in close contact with the bottom of the pedal (2) when not playing The opening and closing plate rises to block the entrance of the pedal guide hole, and if you press the pedal while playing, the opening and closing plate (7) is lowered like the pedal, so the pedal can be operated so that there is no obstacle to the performance and the coil spring is released when the pressure is released. Opening plate (7) is raised by the elasticity of the pedal guide hole (3) to close the opening to close the gap, so that small animals such as mice can not enter the pedal guide hole (3) and the opening and closing plate fixture (4) Due to the vertical guide holes 6 and 6a of (4a), the opening and closing plate 7 can be installed on the pedal guide hole 3 so as to be raised and lowered so that the opening and closing plate can be installed precisely and easily. It may be that this facility will be a practical, easy advantage.
