본 고안은 디지탈 피아노(Digital Piano)의 햄머암 브라켓(Hammer Arm Bracket) 체결구조에 관한 것으로, 더욱 상세하게는 햄머암 브라켓과 건반프레임을 손쉽게 체결할 수 있고, 그 체결상태 또한 견고하게 유지할 수 있도록 한 것이다.The present invention relates to the structure of fastening the hammer arm bracket of the digital piano, and more particularly, the hammer arm bracket and the keyboard frame can be easily fastened, and the fastening state can also be maintained firmly. It is.
일반적으로, 디지탈 피아노의 건(鍵)터치감을 어코스틱 피아노(Acoustic Piano; 일반피아노)의 건터치감과 동일하게 하기 위한 노력으로서, 최근 어코스틱 피아노의 액션구조(Action Mechanism)중 햄머암 기능을 디지탈 피아노의 건반장치에 적용하려는 여러시도가 있어 왔으며 이에 따라 상기 햄머암을 장착하기 위한 별도의 햄머암 브라켓을 건반프레임에 체결하는 것이 필요하였다.In general, in an effort to make the touch feel of a digital piano the same as the touch touch of an acoustic piano, the hammer arm function of the recent action mechanism of an acoustic piano is digital. There have been several attempts to apply the keyboard device of the piano, and accordingly, it was necessary to fasten a separate hammer arm bracket to the keyboard frame for mounting the hammer arm.
그러나, 종래에는 이와 같은 햄머암 브라켓과 건반프레임을 체결함에 있어서, 별도의 스크류를 이용하여 서로 결합하여야 함에 따라 작업이 번거롭고, 체결후 장시간 경과한 뒤에는 스크류의 조임상태가 이완되어 그 체결상태가 견고하지 못하게 됨에 따라 건터치감에 커다란 영향을 미치게 된다는 문제가 있었다.However, conventionally, in fastening such a hammer arm bracket and a keyboard frame, the work is cumbersome because they must be coupled to each other by using a separate screw, and after a long time after tightening, the tightening state of the screw is relaxed and the fastening state is firm. There was a problem that will not be able to have a big impact on the sense of touch.
본 고안은 이와 같은 문제점을 해결하기 위한 것으로, 디지탈 피아노의 햄머암 브라켓상에 결합돌기를 일체로 돌설하고 건반프레임 상에는 상기 결합돌기를 삽입 고정하는 체결공을 형성하여, 상호 끼워맞춤에 의하여 체결이 이루어지도록 하므로써 건반프레임과 햄머암 브라켓을 손쉽고, 견고하게 체결할 수 있도록 한 새로운 형태의 디지탈 피아노의 햄머암 브라켓 체결구조를 제공하고자 하는데 목적이 있다.The present invention is to solve such a problem, by integrally protruding the engaging projection on the hammer arm bracket of the digital piano and forming a fastening hole for inserting and fixing the engaging projection on the keyboard frame, the fastening by the mutual fit The purpose of the present invention is to provide a hammer arm bracket fastening structure of a digital piano of a new type that enables the keyboard frame and hammer arm bracket to be easily and firmly fastened.
이하, 첨부된 도면에 의하여 본 고안을 보다 더 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
본 고안은 제 1 도에 도시된 바와 같이, 햄머암 지지편(10)이 나란히 세워 설치된 통상의 햄머암 브라켓(12)의 뒤쪽평면 양쪽에 그 단면이 "T"자형을 이루는 결합돌기(14)를 돌설하고, 상기 각 결합돌기(14)의 중심선 뒤쪽에는 탄성의 걸림편(16)을 형성하는 한편, 건반프레임(18)의 앞쪽저면에는 상기 결합돌기(14)를 돌설하고, 상기 각 결합돌기(14)의 중심선 뒤쪽에는 탄성의 걸림편(16)을 형성하는 한편, 건반프레임(18)의 앞쪽저면에는 상기 결합돌기(14)와 대응하는 지점에 체결공(20)을 형성하고, 상기 체결공(20)과 일직선상의 모서리부에는 걸림편 착탈공(22)을 형성하여 된 특징을 갖는다.The present invention, as shown in Figure 1, the engaging arm 14, the cross-section of the "T" shape on both sides of the rear surface of the conventional hammer arm bracket 12 installed side by side with the hammer arm support piece (10) And a resilient engaging piece 16 is formed at the rear of the center line of each of the engaging projections 14, while protruding the engaging projections 14 to the front bottom of the keyboard frame 18, and each engaging projection. An elastic locking piece 16 is formed behind the center line of the center 14, while a fastening hole 20 is formed at a point corresponding to the engaging protrusion 14 on the front bottom of the key frame 18, and the fastening is performed. The corner portion of the ball 20 and the straight line has a feature that is formed by the engaging piece detachable hole (22).
이와 같은 본 고안에서 햄머암 브라켓(12)상에 형성되는 걸림편(16)좌우를 절개하여 탄성을 갖도록 하고, 걸림편(16)의 후단부에는 걸림돌기(16a)를 돌설한 구조로 이루어진다.In the present invention, the locking piece 16 formed on the hammer arm bracket 12 is cut out to have elasticity, and the rear end of the locking piece 16 has a structure in which the locking protrusion 16a protrudes.
한편, 건반프레임(18)상의 체결공(20)은 제 1 도에 도시된 바와 같이, 결합돌기(14) 전체가 삽입되는 넓은 부분과, 결합돌기(14) 전체가 삽입된 상태에서 결합돌기(14)의 받침부분을 밀어끼울 수 있는 좁은 부분으로 된 병목형상으로 형성하고, 걸림편 착탈공(22)은 건반프레임(18)의 앞쪽저면의 모서리를 중심으로 수직면과 수평면에 걸쳐 적당한 크기로 형성한 구조로 이루어진다.Meanwhile, as shown in FIG. 1, the fastening hole 20 on the keyboard frame 18 has a wide portion into which the entire coupling protrusion 14 is inserted, and the coupling protrusion 14 in the state in which the entire coupling protrusion 14 is inserted. 14) is formed in a bottleneck shape of a narrow portion that can be pushed in the support portion, the engaging piece detachable hole 22 is formed in a suitable size across the vertical plane and horizontal plane around the edge of the front bottom of the keyboard frame (18). It consists of one structure.
이와 같은 본 고안에서 햄머암 브라켓(12)과 건반프레임(18)의 체결은 다음과 같이 이루어진다.In this invention, the fastening of the hammer arm bracket 12 and the keyboard frame 18 is made as follows.
제 2 도에 도시된 바와 같이, 햄머암 브라켓(12)상의 결합돌기(14)를 건반프레임(18) 저면에 형성된 체결공(20)의 넓은 부분에 끼운다음 건반프레임(18)의 앞쪽으로 밀면, 결합돌기(14)의 받침부분이 체결공(20)의 좁은 부분에 끼워짐과 동시에 햄머암 브라켓(12)상의 걸림편(16)이 건반프레임(18) 저면 모서리부분의 걸림편 착탈공(22)에 스냅방식으로 끼워지게 되어 상호 체결이 완료된다.As shown in FIG. 2, when the engaging projection 14 on the hammer arm bracket 12 is inserted into the wide part of the fastening hole 20 formed on the bottom of the key frame 18, the front side of the key frame 18 is pushed. At the same time, the supporting portion of the coupling protrusion 14 is fitted to the narrow portion of the fastening hole 20, and at the same time, the locking piece 16 on the hammer arm bracket 12 is attached to the locking piece at the bottom edge of the bottom of the keyboard frame 18 ( 22) is snap-fitted to each other is completed.
이같은 상태로부터 체결상태를 해체하고자 하는 경우에는 걸림편 착탈공(22)에 끼워진 걸림편(16)의 걸림돌기(16a)를 손이나 기타 도구로 아래쪽으로 누른 다음, 체결시와는 반대로 결합돌기(14)를 체결공(20)의 넓은 부분으로 잡아당긴 후 아래쪽으로 이탈시키면 된다.In such a case, when the fastening state is to be disassembled, the locking projection 16a of the locking piece 16 inserted into the locking piece removal hole 22 is pushed downward with a hand or other tool, and then the locking projection ( 14) and pulled out to the lower portion of the fastening hole 20 after pulling.
이와 같은 본 고안을 적용하면 체결시 스크류 및 드라이버 같은 스크류를 다루기 위한 별도의 공구가 필요없기 때문에 체결 및 해체작업이 용이하고, 일단 체결된 상태에서는 장시간 경과시에도 시종 견고성이 유지되므로 건터치감에 영향을 미치지 않아 제품에 대한 신뢰도를 제고시킬 수 있다는 효과가 있다.When the present invention is applied, fastening and dismantling work is easy because there is no need for a separate tool for handling screws such as screws and drivers at the time of fastening. There is an effect that can increase the reliability of the product without affecting.
