완충장치가 구비된 도어록{Door lock having device for absorbing shock}Door lock having device for absorbing shock

본 발명은 도어록 핸들에 완충장치를 구비하여 도어 개폐시 도어록 핸들과 부딪치는 벽면이나 벽지를 보호하고 도어록이 그 충격으로 파손되는 것을 방지할 수 있게 한 것이다.The present invention is provided with a shock absorber on the door lock handle to protect the wall or wallpaper hit the door lock handle when opening and closing the door and to prevent the door lock from being damaged by the impact.

종래의 도어록은 외부로 돌출된 도어록에 완충장치가 없으므로 도어를 개폐할 때 도어에 부착된 도어록 핸들이 벽면에 부딪쳐서 벽면이 손상되거나 벽면에 부딪치는 충격으로 도어록이 손상되어 고장을 유발하고 심하면 못쓰게 되는 문제점이 있었고, 이를 방지하기 위해 별도의 보호장구를 부착하고 있으나 비용이 많이 들고 외관도 깔끔하지 못한 문제점이 있었다.Conventional door locks do not have a shock absorber in the door lock that protrudes to the outside, and when the door is opened or closed, the door lock handle attached to the door hits the wall and the wall is damaged or the door lock is damaged due to the impact hitting the wall, causing the failure and severely failing. There was a problem, and to prevent this, a separate protective gear is attached, but there is a problem that the cost is not neat and clean.

본 발명은 상기와 같은 문제점을 해소하기 위하여 도어록 핸들에 완충장치를 구비하여 도어를 열때 도어록의 이동범위에 있는 벽면이 도어록 핸들과의 충돌에서 보호될 수 있게 하고 도어록의 손상도 방지할 수 있게 한 것이다.The present invention is provided with a shock absorber on the door lock handle to solve the above problems, so that the wall surface in the moving range of the door lock when the door is opened can be protected from collision with the door lock handle and also prevent damage to the door lock will be.

본 발명은 도어록의 핸들부분에 완충장치를 하여 도어를 개방할 때 도어록이 충돌하여 손상되는 것을 방지하고 도어록과 충돌하는 벽면도 보호할 수 있게 한 것이다.The present invention prevents the door lock from colliding when the door is opened with a shock absorber on the handle portion of the door lock, and also protects the wall surface colliding with the door lock.

본 발명은 도어록을 도구에 부착하여 개폐하게 되면 도면 표면에서 일정높이로 돌출되는 도어핸들(2)의 결합공(20)끝에 완충돌기(6)가 장치되어 완충자(5)와 연결되어 있고 완충자(5)의 내측은 스프링(4)에 탄발되게 되므로 도어를 열 때 도어핸들이 벽에 부딪친다해도 완충돌기(6)가 먼저 벽면에 닿아 1차 완충되면서 완충자의 완충작용에 의하여 벽지나 도어록에 가해지는 충격을 완화시키게 되므로 벽지나 도어록이 충격으로 손상되는 것을 예방할 수 있고, 이로인해 도어외면에 별도의 보호장구를 부착하지 않아도 되기 때문에 외관이 깔끔한 도어록을 구비할 수 있고 사용하기도 좋은 이점을 얻는 것이다.In the present invention, when the door lock is attached to the tool to open and close, the shock absorbing projection 6 is installed at the end of the coupling hole 20 of the door handle 2 protruding to a certain height from the drawing surface, which is connected to the shock absorber 5, Since the inside of the ruler 5 is elastic to the spring 4, even if the door handle hits the wall when the door is opened, the shock absorbing protrusion 6 first touches the wall and is first cushioned, so that the shock absorbing effect of the wallpaper or the door lock Since the impact to the side can be alleviated, the wall or door lock can be prevented from being damaged by the impact. This eliminates the need to attach a separate protective device to the outside of the door, so that the door lock has a neat appearance and can be used. To get.

본 발명은 도어록뭉치(1) 외측면에 결합되어 통상의 방법으로 도어랫치를 개 폐하는 도어핸들(2)에 완충장치를 부착하여 도어록을 보호하고 벽면이나 벽지가 손상되지 않게 한 것으로 보다 구체적인 것은 도어핸들의 결합봉(20) 중심부에 중심선을 따라 입구에 직경이 적은 원형 안내공(3a)을 형성하여 그 내면에 단턱(3b)이 형성되게 완충실(3)을 형성하고 내부에 스프링(4)을 장치하여 스프링에 탄발되며 완충실 안내공(3a)으로 돌출부(5b)가 노출하고 돌출부보다 직경이 큰 본체부(5a)가 완충실내에 수장되며 본체부와 돌출부사이에 단턱(5c)이 구비된 완충자(5)을 완충자 돌출부(5b)에 중심선을 따라 결합공(5d)을 형성하되 그 입구에 돌기투입구(5e)와 돌기걸림부(5f)을 형성시켜서 결합공(5d)에 탄성체로 되어 결합공(6a)에 걸림돌기(6b)가 형성되어 있는 완충돌기(6)를 강제 결합하여서 되는 구성이다.The present invention is attached to the outer surface of the door lock bundle (1) by attaching a shock absorber to the door handle (2) for opening and closing the door latch in a conventional manner to protect the door lock and to prevent damage to the wall or wallpaper. A circular guide hole 3a having a small diameter is formed along the center line at the center of the engaging rod 20 of the door handle, and a buffer chamber 3 is formed to form a step 3b on the inner surface thereof and a spring 4 therein. Is installed in the buffer chamber, and the protrusion 5b is exposed to the buffer chamber guide hole 3a, and the main body 5a having a larger diameter than the protrusion is stored in the buffer chamber, and a step 5c is provided between the main body and the protrusion. Form the coupling hole 5d along the center line of the buffer 5 provided in the buffer protrusion 5b, and forming a projection inlet 5e and a projection catching portion 5f at the entrance thereof to the coupling hole 5d. Shock absorbing protrusion (1) is formed of an elastic body and has a locking projection (6b) formed in the coupling hole (6a) It is a configuration by forcibly combining 6).
