도어클로저 암 조절장치{Door closer arm adjuster}Door closer arm adjuster

본 발명은 도어클로저 암 조절장치에 관한 것으로서, 더욱상세하게는 도어측 암을 사각 슬리브 형태로 절곡하고 문틀측 암은 판재로 형성하여 상기 도어측 암 내부에서 슬라이드되도록 하고 또한 조절나사를 통하여 다단계로 길이조절되며 조절위치가 식별되도록 함으로써, 도어측 암을 단일체로 구성할 수 있으므로 암의 생산성이 향상되고 조절위치가 식별되므로 조절나사의 체결이 정확해지는 도어클로저 암 조절장치에 관한 것이다.The present invention relates to a door closer arm adjusting device, and more particularly, bending the door arm into a square sleeve shape, and forming the door frame arm with a plate material so that it slides inside the door arm, and can be performed in multiple steps through an adjusting screw. By allowing the length to be adjusted and the adjustment position to be identified, the door side arm can be configured as a single body, so the productivity of the arm is improved and the adjustment position is identified, so that the fastening of the adjustment screw is accurate.

일반적으로 도어클로저(door closer)는 열린 문을 자동적으로 닫는 장치로써, 금속 스프링과 오일 댐퍼의 조합으로 구성되며 문 위쪽에 설치된다. 도어클로저 본체는 도어에 장착되고 도어클로저에서 돌출되는 레버는 도어암을 통하여 문틀에 연결된 문틀암과 연결된다. 따라서 도어를 여닫는 과정에서 이들 암이 절첩되면서 레버가 회동되므로 도어클로저 내부의 오일 댐퍼 작동으로 열린 도어가 부드럽게 닫힌다.In general, a door closer is a device that automatically closes an open door, is composed of a combination of a metal spring and an oil damper, and is installed above the door. The door closer body is mounted on the door, and the lever protruding from the door closer is connected to the door frame arm connected to the door frame through the door arm. Therefore, as these arms are folded in the process of opening and closing the door, the lever rotates, so the opened door is smoothly closed by the operation of the oil damper inside the door closer.

도어클로저의 암은 길이조절이 되도록 도어암과 문틀암으로 분리 구성되는데, 문틀암이 도어암의 내부에서 슬라이드되거나 또는 나사체결 방식으로 길이조절된다.The arm of the door closer is separated into a door arm and a door frame arm so that the length can be adjusted.

종래 공개실용신안 제1998-042873호는 슬라이드 방식으로 길이조절되는 암 구조를 나타낸 것으로서, 도어암에 해당되는 암슬리브가 상하측으로 분리 구성되고, 문틀암에 해당되는 연동암에는 다수의 고정홈이 연속으로 형성되며, 상기 하부 암슬리브에는 상기 고정홈으로 끼워지는 고정돌기가 돌출형성된 것이다.Conventional Public Utility Model No. 1998-042873 shows an arm structure that can be adjusted in length by a slide method, in which an arm sleeve corresponding to a door arm is separated up and down, and a plurality of fixing grooves are continuous in an interlocking arm corresponding to a door frame arm. is formed, and a fixing protrusion to be fitted into the fixing groove is protruded from the lower arm sleeve.

길이조절을 위하여 상기 상하측으로 분리된 암슬리브를 체결하는 고정볼트를 풀어서 상하측 암슬리브가 느슨해지도록 간격을 벌린 뒤 상기 고정돌기가 원하는 특정 고정홈으로 끼워지도록 연동암을 좌우측으로 움직인 뒤 재차 고정볼트를 조여서 이들 상하측으로 벌어진 암슬리브를 체결하는 방식이다.To adjust the length, loosen the fixing bolts for fastening the upper and lower arm sleeves to loosen the upper and lower arm sleeves, and then move the interlocking arm to the left and right so that the fixing protrusion fits into the desired specific fixing groove and then fix it again. This is a method of fastening the upper and lower arm sleeves by tightening the bolts.

그러나 종래 길이조절과정에서 고정볼트를 풀면 상하측으로 분리된 암슬리브가 벌어지는 과정에서 암슬리브 선단의 힌지부에 해당되는 부시의 조립위치가 틀어지므로 고정볼트를 다시 체결할때 부시의 체결위치를 조절해야되는 번거로움이 있으며, 또한 연동암의 길이를 수시로 빈번하게 조정할 경우 고정볼트를 풀고 이들 상하측으로 분리된 암슬리브 간격을 벌려주는 과정이 반복되므로 작업성이 매우 까다로운 단점이 있었다. 또한 암슬리브가 상하측으로 분리되므로 이들 분리된 암슬리브를 프레스 펀칭으로 제작하기 위한 금형 개수가 증가되는 등의 문제점이 있었다.However, in the process of loosening the fixing bolt in the conventional length adjustment process, the assembly position of the bush corresponding to the hinge part of the tip of the arm sleeve is changed in the process of opening the upper and lower arm sleeves. In addition, when the length of the interlocking arm is frequently adjusted, the process of loosening the fixing bolt and widening the upper and lower arm sleeves is repeated, so workability is very difficult. In addition, since the arm sleeve is separated up and down, there is a problem in that the number of molds for manufacturing the separated arm sleeve by press punching is increased.

본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 도어측 암을 사각 슬리브 형태로 절곡하고 문틀측 암은 판재로 형성하여 상기 도어측 암 내부에서 슬라이드되도록 하고 또한 조절나사를 통하여 다단계로 길이조절되며 조절위치가 식별되도록 함으로써, 도어측 암을 단일체로 구성할 수 있으므로 암의 생산성이 향상되고 조절위치가 식별되므로 조절나사의 체결이 정확해지는 도어클로저 암 조절장치를 제공함에 있다.The present invention was developed in consideration of the problems of the prior art, and an object of the present invention is to bend the door arm into a square sleeve shape, and form the door frame arm with a plate material so that it slides inside the door arm, and also through an adjusting screw. An object of the present invention is to provide a door closer arm adjusting device in which the adjustment screw is accurately fastened because the length of the arm is adjusted in multiple stages and the adjustment position is identified, so that the door side arm can be configured as a single body, thereby improving the productivity of the arm and identifying the adjustment position.

이를 위하여 본 발명은 도어 상단에 고정되는 클로저본체에 레버가 돌출 구비되고, 상기 레버에 힌지부를 통하여 연결되는 도어암이 구비되며, 상기 도어암이 슬라이드되게 문틀에 힌지부를 통하여 결합되는 문틀암이 구비되고, 상기 문틀암에는 상기 도어암에 걸리는 조절나사가 구비되어서 도어암과 문틀암의 체결위치가 조절되도록 한 도어클로저 암 조절장치에 있어서, 상기 도어암 내부 바닥면에 다수의 홈이 등간격으로 구비되어서 상기 조절나사 끝단의 첨단부가 선택적으로 끼워져 걸리며; 상기 도어암 윗면에는 상기 조절나사가 돌출되게 개방부가 길이방향으로 천공되어서 슬라이드 과정에서 상기 조절나사가 걸리지 않도록 한 특징이 있다.To this end, the present invention is provided with a lever protruding from the closer body fixed to the top of the door, a door arm connected to the lever through a hinge portion, and a door frame arm coupled to the door frame through the hinge portion so that the door arm slides. In the door closer arm adjusting device, the door frame arm is provided with an adjusting screw that is caught on the door arm so that the fastening position of the door arm and the door frame arm is adjusted, wherein a plurality of grooves are provided on the inner bottom surface of the door arm at equal intervals. provided so that the tip of the end of the adjusting screw is selectively fitted and caught; The opening part is perforated in the longitudinal direction so that the adjusting screw protrudes from the upper surface of the door arm, so that the adjusting screw is not caught in the slide process.

본 발명에 따르면 도어측에 연결된 도어암을 슬리브 형태가 되게 직사각형으로 절곡하고, 문틀암은 상기 도어암에 끼워지는 판재 형태로 제작하기 때문에 생산이 편리한 이점이 있다. 또한 도어암 내측면에 다수의 홈이 일정간격으로 형성되고, 상기 문틀암에 체결되는 조절나사의 끝단은 상기 어느 한 홈에 걸려서 문틀암과 도어암의 길이가 조절된다.According to the present invention, since the door arm connected to the door is bent into a rectangle to form a sleeve, and the door frame arm is manufactured in the form of a plate to be fitted into the door arm, there is an advantage in convenient production. In addition, a plurality of grooves are formed on the inner surface of the door arm at regular intervals, and the end of the adjusting screw fastened to the door frame arm is caught in one of the grooves to adjust the length of the door frame arm and the door arm.

상기 도어암의 윗면은 조절나사가 돌출되게 길이방향으로 일부 개방되기 때문에 조절나사를 문틀암에서 완전 분리시킬 필요가 없으므로 길이조절이 편리한 이점이 있다. 또한 문틀암에는 상기 도어암의 홈에 선택적으로 끼워져 걸리는 볼이 탄성적으로 구비되기 때문에 문틀암을 슬라이드시키는 과정에서 볼이 각 홈에 탄성적으로 걸리면 조절나사와 홈이 일직선상에 놓이므로 조절나사와 홈의 체결위치가 정확해진다.Since the upper surface of the door arm is partially opened in the longitudinal direction so that the adjusting screw is protruded, there is no need to completely separate the adjusting screw from the door frame arm, so it is convenient to adjust the length. In addition, since the door frame arm is elastically provided with a ball that is selectively fitted into the groove of the door arm, when the ball is elastically caught in each groove in the process of sliding the door frame arm, the adjusting screw and the groove are placed in a straight line. and the joint position of the groove becomes accurate.

따라서 작업자가 느낌으로 조절나사와 홈의 위치를 가늠할 필요가 없으며 또한 부정확한 체결로 인하여 홈이 파손되는 일이 방지되므로 제품의 신뢰성이 향상되는 등의 이점이 있다.Therefore, there is no need for the operator to determine the position of the adjusting screw and the groove by feeling, and also, since the groove is prevented from being damaged due to inaccurate fastening, the reliability of the product is improved.

It is composed of a door arm 20 connected to the hinge 23 through the door frame 41 and a door frame arm 30 connected to the door frame 41 through a bracket 42 and a hinge unit 37 .

상기 도어암(20)은 단면이 직사각형인 슬리브 형태로써, 내부가 중공상으로 구성되게 판재를 절곡한 것으로 단일체로 구성되므로 부품이 간소화되는 이점이 있다. 또한 상기 도어암(20)의 윗면은 길이방향으로 천공되어 내부가 노출되는 개방부(22)가 형성되고, 내측 바닥면은 길이방향으로 다수의 홈(21)이 구비된다. 이들 홈(21)은 등간격으로 형성되며, 상기 홈(21)에 끼워지는 첨단부(31a)가 하단에 형성되는 조절나사(31)가 구비된다.The door arm 20 is in the form of a sleeve having a rectangular cross-section, and since it is composed of a single body by bending a plate material so that the inside is configured in a hollow shape, parts are simplified. In addition, the upper surface of the door arm 20 is perforated in the longitudinal direction to form the opening 22 exposing the inside, and the inner bottom surface is provided with a plurality of grooves 21 in the longitudinal direction. These grooves 21 are formed at equal intervals, and an adjustment screw 31 having a tip portion 31a fitted into the groove 21 is provided at the lower end thereof.

상기 문틀암(30)은 상기 도어암(20)이 슬라이드 되게 단면이 직사각형의 판재로 구성되며, 상기 조절나사(31)가 체결되는 나사구멍(32)이 선단에 천공된다. 그리고 후단에는 상기 문틀(41)의 브래킷(42)에 회동가능하게 결합되는 힌지부(37)가 구비되고, 또한 상기 도어암(20)의 선단에도 상기 레버(11)와 회동가능하게 결합되는 힌지부(23)가 구비된다.The door frame arm 30 is made of a plate material having a rectangular cross section so that the door arm 20 slides, and a screw hole 32 to which the adjusting screw 31 is fastened is drilled at the tip end. A hinge portion 37 rotatably coupled to the bracket 42 of the door frame 41 is provided at the rear end, and a hinge rotatably coupled to the lever 11 at the front end of the door arm 20 as well. A branch 23 is provided.

그리고 상기 문틀암(30)에 천공된 나사구멍(32)은 상기 도어암(20)의 각 홈(21)과 일치되게 일직선상에 천공되며, 상기 나사구멍(32)과 떨어지게 관통구멍(36)이 문틀암(30)에 천공된다. 상기 관통구멍(36)과 나사구멍(32)은 상기 각 홈(21)의 떨어진 간격과 동일하게 유지되며, 상기 관통구멍(36)에는 스프링(34)과 볼(35)이 내장된 볼캡(33)이 체결된다. 상기 볼캡(33)은 밑면이 개방되어서 상기 내장된 볼(35)이 도어암(20)의 내측 바닥면에 밀착된다. 따라서 문틀암(30)이 슬라이드되는 과정에서 볼(35)이 각 홈(21)을 탄성적으로 타고 넘는다.And the screw hole 32 drilled in the door frame arm 30 is drilled in a straight line to coincide with each groove 21 of the door arm 20, and the through hole 36 is separated from the screw hole 32. It is perforated in this door frame arm (30). The through hole 36 and the screw hole 32 are maintained at the same distance between the respective grooves 21, and the through hole 36 has a ball cap 33 having a built-in spring 34 and a ball 35. ) is signed. The bottom of the ball cap 33 is opened so that the embedded ball 35 is in close contact with the inner bottom surface of the door arm 20 . Therefore, the ball 35 elastically rides over each groove 21 while the door frame arm 30 slides.

이처럼 구성된 본 발명 한 실시예의 암 조절장치는 도어암(20) 내부 바닥에 다수의 홈(21)이 등간격으로 형성되고, 문틀암(30)에는 상기 각 홈(21)에 끼워져 걸리는 조절나사(31) 및 볼캡(33)이 체결된다. 상기 조절나사(31)의 끝단은 상기 각 홈(21)에 끼워지는 첨단부(31a)가 형성되어서 조절나사(31)를 체결하는 과정에서 첨단부(31a)가 홈(21)에 완전히 끼워지면 문틀암(30)이 도어암(20)에 고정된다.In the arm adjusting device of one embodiment of the present invention configured as described above, a plurality of grooves 21 are formed at equal intervals on the inner bottom of the door arm 20, and an adjustment screw ( 31) and the ball cap 33 are fastened. The end of the adjusting screw 31 is formed with a tip portion 31a fitted into each groove 21 so that, in the process of fastening the adjustment screw 31 , the tip portion 31a is completely fitted into the groove 21 . The door frame arm 30 is fixed to the door arm 20 .

또한 조절나사(31)의 첨단부(31a)가 어느 한 홈(21)에 끼워지면 볼(35)이 다른 홈(21)에 들어간 상태가 된다. 이런 상태에서 조절나사(31)를 풀면 첨단부(31a)가 홈(21)에서 빠지므로 도어암(20)이 문틀암(30)을 따라 슬라이드 가능 상태가 된다. 따라서 도어(40)를 닫은 상태에서 레버(11)를 좌우측으로 강제 회전시키면 도어암(20)이 문틀암(30)을 따라 슬라이드되면서 이들 사이 간격이 조절된다. 또한 조절나사(31)와 볼캡(33)은 개방부(22)를 통하여 도어암(20) 위쪽으로 돌출되므로 도어암(20)의 슬라이드에 지장을 주지 않는다.In addition, when the tip 31a of the adjusting screw 31 is inserted into one groove 21 , the ball 35 enters the other groove 21 . In this state, when the adjusting screw 31 is loosened, the tip part 31a is removed from the groove 21 , so that the door arm 20 can slide along the door frame arm 30 . Accordingly, when the lever 11 is forcibly rotated to the left and right in a state in which the door 40 is closed, the door arm 20 slides along the door frame arm 30 to adjust the gap between them. In addition, since the adjusting screw 31 and the ball cap 33 protrude upward through the opening part 22 , the sliding of the door arm 20 is not hindered.

상기 볼캡(33) 내부의 볼(35)은 도어암(20)의 내부 바닥면과 접촉된 상태에서 스프링(34)을 통하여 탄성적으로 힘을 받고 있으므로 볼(35)이 도어암(20)의 바닥면과 홈(21)에 번갈아 접촉된다. 따라서 볼(35)이 홈(21)에 들어가는 순간 도어암(20)이 순간 정지되는데, 작업자는 원하는 위치에서 볼(35)과 홈(21)이 일치되면 조절나사(31)를 조인다. 만약 원하는 지점이 아니면 레버(11)를 계속 움직여서 볼(35)이 다른 홈(21)에 들어가도록 하고 이때 조절나사(31)를 체결하면 첨단부(31a)가 볼(35)과 떨어진 다른 홈(21)으로 들어간다.Since the ball 35 inside the ball cap 33 is elastically receiving a force through the spring 34 while in contact with the inner bottom surface of the door arm 20 , the ball 35 moves the door arm 20 . The bottom surface and the groove 21 are alternately in contact. Accordingly, the door arm 20 is momentarily stopped as soon as the ball 35 enters the groove 21 , and the operator tightens the adjusting screw 31 when the ball 35 and the groove 21 match at a desired position. If it is not the desired point, keep moving the lever 11 so that the ball 35 enters the other groove 21, and at this time, when the adjusting screw 31 is tightened, the tip 31a is moved to another groove away from the ball 35 ( 21) is entered.

도어암(20)과 문틀암(30)은 도어(40)의 상측에 설치되기 때문에 작업자가 도어암(20) 내부의 홈(21)을 볼수 없으며, 또한 문틀암(30)이 도어암(20) 내부로 들어가기 때문에 홈(21)이 가려져서 볼수 없는 상태이다. 이런 상태에서 조절나사(31)를 풀고 도어암(20)을 움직이면 조절나사(31)가 다른 홈(21)과 일치되었는지 알수 없으므로 작업자가 조절나사(31)를 풀었다 조였다를 반복하면서 첨단부(31a)가 원하는 홈(21)에 들어가도록 조절해야되는 번거로움이 있다.Since the door arm 20 and the door frame arm 30 are installed on the upper side of the door 40 , the operator cannot see the groove 21 inside the door arm 20 , and the door frame arm 30 is installed on the door arm 20 . ) because it enters the inside, the groove 21 is covered and cannot be seen. In this state, if the adjusting screw 31 is loosened and the door arm 20 is moved, it is not known whether the adjusting screw 31 coincides with the other grooves 21. 31a) is inconvenient to be adjusted to enter the desired groove (21).

그러나 본 발명 한 실시예는 볼(35)이 홈(21)에 들어가면 탄성적으로 걸리면서 도어암(20)이 순간 정지되므로 이때 조절나사(31)를 체결하면 첨단부(31a)가 홈(21)에 정확하게 들어가므로 조절작업이 편리한 이점이 있다.However, in one embodiment of the present invention, when the ball 35 enters the groove 21, it is elastically caught and the door arm 20 is momentarily stopped. It has the advantage of convenient adjustment work because it is accurately entered into the
