The first chamber 211 and the second chamber 213 are provided inside the housing 210 and can be defined as one space in which the above-described components can be arranged. The lower sides of the first chamber 211 and the second chamber 213 may be opened so that the lever 240 and the elastic member 250 may be assembled into the housing 210, and a portion of the upper side of the second chamber 213 may be The cam member 230 and the shaft 220 may be assembled into the housing 210 through the upper side thereof so that the cam member 230 and the shaft 220 may be opened.
제 1실(211)의 일측에는 탄성부재(250)의 일단을 지지하는 지지면(212)이 마련될 수 있다. 지지면(212)에는 탄성부재(250)의 일단이 지지되고 이에 따라 레버(240)가 캠부재(230)의 회전에 연동되어 선형 운동할 시 탄성부재(250)가 압축될 수 있다.One side of the first chamber 211 may be provided with a support surface 212 for supporting one end of the elastic member 250. One end of the elastic member 250 is supported on the support surface 212, and thus the elastic member 250 may be compressed when the lever 240 linearly moves in conjunction with the rotation of the cam member 230.
샤프트(220)는 도어(100)의 회전축을 형성하고 캠부재(230)와 결합되는 축부(221)와 축부(221)에서 연장되어 절곡되고 도어(100) 내측으로 삽입되는 삽입부(222)를 포함할 수 있다.The shaft 220 forms an axis of rotation of the door 100 and has a shaft portion 221 coupled to the cam member 230 and an insertion portion 222 extending from the shaft portion 221 and bent and inserted into the door 100. It may include.
축부(221)는 도어(100)의 회전에 연동되어 도어(100)가 회전되는 방향으로 회전되고 이에 따라 도어(100)의 회전력을 캠부재(230)에 전달될 수 있다. 다르게 표현하자면 축부(221) 상에는 도어(100)의 회전축인 동시에 캠부재(230)의 회전축이 마련되어 축부(221)를 중심으로 하여 도어(100)와 캠부재(230)가 회전될 수 있다.The shaft portion 221 may be linked to the rotation of the door 100 to rotate in the direction in which the door 100 is rotated, thereby transmitting the rotational force of the door 100 to the cam member 230. In other words, the rotation axis of the cam member 230 is provided at the same time as the rotation axis of the door 100 on the shaft part 221 so that the door 100 and the cam member 230 may be rotated around the shaft part 221.
삽입부(222)는 축부(221)와 대략 직교되는 각도로 절곡되어 도어(100)의 내측에 삽입될 수 있다. 삽입부(222)는 축부(221)를 중심으로 도어(100)와 함께 회전될 수 있다. The inserting portion 222 may be bent at an angle orthogonal to the shaft portion 221 and inserted into the door 100. The insertion part 222 may be rotated together with the door 100 about the shaft part 221.
이에 따라 도어(100)가 폐쇄 상태일 시 축부(221)에 대한 삽입부(222)의 각도가 0도라고 할 때, 삽입부(222)의 각도는 도어(100)가 개구에 대해 상하 방향으로 배치되는 각도와 동일할 수 있다.Accordingly, when the angle of the insertion portion 222 with respect to the shaft portion 221 is 0 degrees when the door 100 is in a closed state, the angle of the insertion portion 222 is disposed in the vertical direction with respect to the opening 100. It may be equal to the angle.
캠부재(230)는 축부(221)가 삽입되는 삽입구(231)를 포함할 수 있다. 축부(221)는 삽입구(231)에 삽입되어 캡부재(230)와 결합될 수 있다. 이에 따라 축부(221)의 회전에 따라 캠부재(230)는 시계 방향 또는 반시계 방향으로 도어(100)와 연동되어 회전될 수 있다.The cam member 230 may include an insertion hole 231 into which the shaft portion 221 is inserted. The shaft portion 221 may be inserted into the insertion hole 231 and coupled with the cap member 230. Accordingly, in accordance with the rotation of the shaft portion 221, the cam member 230 may be rotated in conjunction with the door 100 in a clockwise or counterclockwise direction.
캠부재(230)는 외곽측에 형성되는 곡면(232)을 포함할 수 있다. 곡면(232)의 일측에는 레버(240)가 접하여 캠부재(230)에 레버(240)의 힘이 전달되는 접촉구간(233)이 마련될 수 있다. 접촉구간(233)에 대하여는 자세하게 후술한다.The cam member 230 may include a curved surface 232 formed on the outer side. One side of the curved surface 232 may be provided with a contact section 233 in which the lever 240 is in contact with the cam member 230 to transmit the force of the lever 240. The contact section 233 will be described later in detail.
곡면(232)의 캠부재(230)의 외주면 상에 배치될 수 있으며 다만 이에 한정되지 않고 캠부재(230)의 외곽측에 배치되어 레버(240)와 접할 수 있는 위치에 형성될 수 있다.It may be disposed on the outer circumferential surface of the cam member 230 of the curved surface 232, but is not limited thereto and may be disposed on the outer side of the cam member 230 to be in contact with the lever 240.
레버(240)는 상술한 바와 같이 탄성부재(250)에 탄성 지지되는 일측과 탄성부재(250)의 탄성력에 의해 캠부재(230)를 가압하는 타측을 가질 수 있다. 레버(240)의 일측에는 탄성부재(250) 내측으로 삽입되어 탄성부재(250)의 병진 압축 신장을 가이드하는 가이드부(241)와 탄성부재(250)의 타단을 지지하여 레버(240)에 탄성부재(250)의 탄성력을 전달하는 지지부(242)가 마련될 수 있다.As described above, the lever 240 may have one side that is elastically supported by the elastic member 250 and the other side that presses the cam member 230 by the elastic force of the elastic member 250. One side of the lever 240 is inserted into the elastic member 250 to support the other end of the guide portion 241 and the elastic member 250 to guide the translational compression extension of the elastic member 250 is elastic to the lever 240 Support portion 242 for transmitting the elastic force of the member 250 may be provided.
레버(240)의 타측에는 지지부(242)에서 연장되는 본체(243)가 마련될 수 있다. 본체(243)는 캠부재(230)의 외주면(232)과 접촉하여 캠부재(230)를 가압하는 가압부(244)를 포함할 수 있다.The other side of the lever 240 may be provided with a body 243 extending from the support 242. The main body 243 may include a pressing unit 244 that contacts the outer circumferential surface 232 of the cam member 230 to press the cam member 230.
도 6을 참고할 때 도어(100)가 반시계 방향으로 회전(도어(100)가 폐쇄되는 방향)될수록 탄성부재(250)가 압축되어 지지부(242)에 전달되는 압축력이 증가될 수 있다.Referring to FIG. 6, as the door 100 rotates in the counterclockwise direction (the direction in which the door 100 is closed), the compressive force transmitted to the support part 242 may be increased by compressing the elastic member 250.
이에 따라 가압부(244)는 도어(100)가 폐쇄되는 방향으로 회전할수록 가압구간(233)에 더 큰 힘을 가할 수 있다. 이에 대해서는 상술한 접촉구간(233)과 함께 자세히 하술한다.Accordingly, the pressing unit 244 may apply a greater force to the pressing section 233 as the door 100 rotates in the direction in which the door 100 is closed. This will be described in detail later together with the above-described contact section 233.
하우징(210)의 제 2실(213) 상측에는 캠부재(230)와 샤프트(220)의 조립성을 위해 상술한 바와 같이 개구가 형성될 수 있는데 캠부재(230)와 샤프트(220)가 하우징(210)에 조립된 후 개구를 폐쇄시키는 캡부재(260)가 마련될 수 있다.An opening may be formed above the second chamber 213 of the housing 210 as described above for assembling the cam member 230 and the shaft 220. The cam member 230 and the shaft 220 may be formed in the housing. The cap member 260 may be provided to close the opening after being assembled to the 210.
이하에서는 캠부재(230)에 가해지는 토크에 대하여 설명한다. 설명의 편의를 위하여 도 6를 기준으로 도어(100)가 개방되는 방향을 회전축의 시계방향, 도어가 폐쇄되는 방향을 회전축의 반시계방향으로 정의하여 설명한다.Hereinafter, the torque applied to the cam member 230 will be described. For convenience of description, the direction in which the door 100 is opened will be described as a clockwise direction of the rotating shaft and the direction in which the door is closed as the counterclockwise direction of the rotating shaft, based on FIG. 6.
도 6에 도시된 바와 같이 캠부재(230)에는 레버(240)의 가압으로 형성되는 제 1토크(T1)와 도어(100)의 자중에 의해 형성되는 제 2토크(T2)가 가해질 수 있다. As shown in FIG. 6, the cam member 230 may be applied with the first torque T1 formed by the pressing of the lever 240 and the second torque T2 formed by the weight of the door 100.
제 1토크(T1)는 상하 방향으로 경사지게 배치되는 탄성부재(250)의 압축력에 의하여 회전축의 시계방향으로 회전하는 힘을 캠부재(230)에 전달할 수 있다. 탄성부재(250)의 압축력에 의해 레버(240)에 전달되는 힘을 F1라 하고 F1와 회전축까지의 수직거리를 r1이라 할 때 제 1토크(T1)의 크기는 F1*r1로 구해질 수 있다. The first torque T1 may transmit the force rotating in the clockwise direction of the rotating shaft to the cam member 230 by the compressive force of the elastic member 250 inclined in the vertical direction. When the force transmitted to the lever 240 by the compressive force of the elastic member 250 is F1 and the vertical distance between F1 and the rotating shaft is r1, the size of the first torque T1 may be calculated as F1 * r1. .
다만, 실질적으로 F1는 가압부(244)가 캠부재(230)를 가압할 시 접촉구간(233)의 접선 방향에 따라 힘이 형성되는 방향이 변하고, 이에 따라 실질적인 r1의 길이가 변화될 수 있으나 설명의 편의 상 도 6에서는 제 1토크(T1)는 F1는 탄성부재(250)의 압축방향으로 향한다고 가정하고 이에 따라 r1이 일정하게 유지된다고 가정하고 도시하였다.However, in F1, the direction in which the force is formed is changed according to the tangential direction of the contact section 233 when the pressing unit 244 presses the cam member 230, and thus the length of the actual r1 may be changed. For convenience of description, in FIG. 6, the first torque T1 assumes that F1 is directed in the compression direction of the elastic member 250, and accordingly assumes that r1 is kept constant.
제 2토크(T2)는 도어(100)의 무게중심(G)에서 발생하는 중력 가속도의 힘(F2)에 의해 회전축의 반시계방향으로 회전하는 힘을 캠부재(230)에 전달할 수 있다. 즉, F2에 의해 회전축의 반시계방향으로 회전하는 힘을 캠부재(230)에 전달할 수 있다. 따라서 제 2토크(T2)는 도어(100)의 자중에서 도어(100)의 무게중심(G)에서 회전축까지의 수직거리(r2)를 곱한 값으로 구해질 수 있다.The second torque T2 may transmit the force rotating in the counterclockwise direction of the rotation shaft to the cam member 230 by the force of gravity acceleration F2 generated at the center of gravity G of the door 100. That is, the force rotating in the counterclockwise direction of the rotation shaft by F2 can be transmitted to the cam member 230. Therefore, the second torque T2 may be obtained by multiplying the vertical distance r2 from the center of gravity G of the door 100 to the rotation axis by the weight of the door 100.
제 1토크(T1)와 제 2토크(T2)는 각각 반대 방향으로 캠부재(230)에 힘을 전달하는 바 제 1토크(T1)와 제 2토크(T2) 중 더 큰 힘이 가해지는 방향으로 캠부재(230)가 회전될 수 있다.The first torque T1 and the second torque T2 transmit the force to the cam member 230 in opposite directions, respectively, and a direction in which the larger force is applied among the first torque T1 and the second torque T2. Cam member 230 can be rotated.
이하에서는 캠부재(230)의 접촉구간(233)과 접촉구간(233)과 접촉하여 캠부재(230)를 가압하는 레버(240)의 가압부(244) 및 가압부(244)에 의해 접촉구간(233) 상에 형성되는 접촉부(234)에 대하여 자세히 설명한다.Hereinafter, the contact section by the pressing section 244 and the pressing section 244 of the lever 240 for pressing the cam member 230 in contact with the contact section 233 and the contact section 233 of the cam member 230. The contact portion 234 formed on the 233 will be described in detail.
본 발명의 실 실시예와 같은 펄세이터 형식의 세탁기의 경우 도어(100)가 캐비닛(10)의 상측에 배치되어 도어(100)를 상측으로 회전시켜 개구(24)를 개방하고, 다시 도어(100)를 하측으로 회전시켜 개구(24)를 폐쇄시킬 수 있다.In the case of the washing machine of the pulsator type as in the exemplary embodiment of the present invention, the door 100 is disposed above the cabinet 10 to rotate the door 100 upward to open the opening 24, and then again the door 100. ) Can be rotated downward to close the opening 24.
도어(100)를 폐쇄시키는 동작에서 도어(100)가 회전축을 중심으로 하측으로 회전되기 때문에 도어(100)가 무거운 경우 중력에 의해 빠르게 도어(100)가 닫히게 되는데 이 때 사용자의 손가락이 도어(100)와 캐비닛(10) 사이에 끼어 안전사고가 발생할 수 있으며 도어(100)가 빠르게 닫힐 경우 캐비닛(10)과 강하게 충돌하여 큰 소음이 발생하는 문제가 있었다.In the operation of closing the door 100, since the door 100 is rotated downwardly about the rotation axis, when the door 100 is heavy, the door 100 is quickly closed by gravity, and the user's finger is moved to the door 100 There is a problem that a safety accident may occur between the cabinet and the cabinet 10, and when the door 100 is quickly closed, a strong noise is generated due to a strong collision with the cabinet 10.
이를 해결하기 위하여 종래의 세탁기는 링크 구조를 통한 도어에 체결 된 핀의 회전동작을 병진운동으로 전환시키고 이 과정에서 발생하는 충격을 스프링의 강성으로 도어의 개폐 동작을 제어하거나 추가적으로 유압 실린더를 설치하여 세탁기 도어의 폐쇄 속도를 제어하도록 하였다.In order to solve this problem, the conventional washing machine converts a rotational motion of a pin fastened to a door through a link structure into a translational motion and controls the opening / closing motion of the door with the rigidity of the spring or installs an additional hydraulic cylinder. The closing speed of the washing machine door was controlled.
안정적으로 제공하는 기술이 있으나 링크구조에 따른 부품 증가와 조립구조가 복잡해 재료비가 증가하는 결과를 가져온다. There is a technology that provides a stable, but the increase in parts and assembly structure according to the link structure results in an increase in material costs.
이와 같은 종래의 세탁기의 경우 도어의 폐쇄속도를 느리게 제어하는 추가 부재가 힌지 유닛에 마련됨에 따라 힌지 유닛의 부피가 커지고 이에 따라 캐비닛의 크기가 커지거나 캐비닛 내측에 마련되는 고정조의 크기가 줄어드는 문제, 링크구조와 같은 추가적인 구성이 늘어남에 따라 조립구조가 복잡해지는 문제, 제조원가가 증가하는 문제가 발생하게 되었다.In the case of such a conventional washing machine, as the additional member for controlling the closing speed of the door is provided in the hinge unit, the volume of the hinge unit increases, thereby increasing the size of the cabinet or reducing the size of the fixing tub provided inside the cabinet. As the additional structure such as link structure is increased, the assembly structure becomes complicated and the manufacturing cost increases.
본 발명의 일 실시예는 이와 같은 문제를 해결하기 위하여 캠부재(230)와 캠부재(230)를 지지하는 탄성부재(250)와 레버(240)의 구성으로 힌지 유닛(200)을 형성하여 힌지 유닛(200)의 동력전달 방식을 단순화하여 신뢰성을 확보하며, 구성의 감소에 따른 부품수 감소로 제조 원가를 절감시킬 수 있는 효과를 발생시킬 뿐만 아니라 사용자의 안전 문제를 해결하며 소음 발생을 방지할 수 있다.One embodiment of the present invention is hinged by forming a hinge unit 200 in the configuration of the cam member 230 and the elastic member 250 and the lever 240 for supporting the cam member 230 to solve such problems Simplify the power transmission method of the unit 200 to ensure reliability, and to reduce the number of parts due to the reduction of the configuration not only to produce the effect of reducing the manufacturing cost, but also to solve the user's safety problems and to prevent noise Can be.
즉, 캠부재(230)에 탄성부재(250)의 힘을 전달하는 레버(240)가 직접 접하게 함에 따라 기존의 캠부재와 레버와 대응되는 슬라이더와 같은 구성 사이에 배치되는 링크 구조 등의 구성이 힌지 유닛(200)의 구성에 제외될 수 있게 하였다.That is, as the lever 240 directly transmitting the force of the elastic member 250 to the cam member 230 is in direct contact, the link structure is disposed between the existing cam member and a configuration such as a slider corresponding to the lever. It can be excluded from the configuration of the hinge unit 200.
따라서 본 발명의 일 실시예에 의할 때 링크 구조 또는 유압 실린더를 배제시킴과 동시에 기존 구성들에 의해 형성되는 효과를 발생시키기 위하여 접촉 구간(233)의 형상을 프로파일하여 레버(240)에 의해 전달되는 힘의 크기를 제어하고 이를 통해 도어(100)의 개폐 속도를 제어할 수 있도록 하였다.Therefore, according to an embodiment of the present invention to profile the shape of the contact section 233 and to transmit by the lever 240 in order to exclude the link structure or the hydraulic cylinder at the same time to produce the effect formed by the existing configuration By controlling the magnitude of the force to be able to control the opening and closing speed of the door 100 through this.
자세하게는 도 7에 도시된 바와 같이 접촉구간(233)에 각각 곡률을 달리하는 제 1구간(A)과 제 2구간(C)과 제 3구간(B)을 설정하여 캠부재(230)가 일방향(반시계방향)으로 회전 시 가압부(244)가 접촉구간(233)을 따라 제 1구간(A)과 3구간(B) 및 2구간(C)을 순차적으로 접하게 되고(캠부재(230)가 타방향으로 회전 시 2-3-1구간(C-B-A) 순으로) 각각의 구간에서 세팅된 곡률을 통해 가압부(244)로부터 전달되는 힘의 값을 제어할 수 있다.In detail, as shown in FIG. 7, the cam member 230 is one-way by setting the first section A, the second section C, and the third section B having different curvatures in the contact section 233, respectively. When rotating in the counterclockwise direction, the pressing unit 244 sequentially contacts the first section A, the third section B, and the second section C along the contact section 233 (cam member 230). When rotating in the other direction, the value of the force transmitted from the pressurizing unit 244 may be controlled through the curvature set in each section in the order of 2-3-1 sections (CBA).
가압부(244)에 의해 가압되는 접촉구간(233) 상의 어느 일 점 또는 어는 범위를 접촉부(234)라고 할 때, 접촉부(234)는 캠부재(230)의 회전으로 AA와 CC사이에 배치될 수 있으며, 접촉부(234)는 캠부재(230)의 회전에 따라 제 1구간(A)과 제 2구간(C) 또는 제 3구간(B) 중 어느 한 구간에 선택적으로 배치될 수 있다.When any one point or freezing range on the contact section 233 pressed by the pressing section 244 is called the contact section 234, the contact section 234 is disposed between AA and CC by the rotation of the cam member 230. The contact part 234 may be selectively disposed in any one of the first section A, the second section C, or the third section B according to the rotation of the cam member 230.
즉, 가압부(244)는 레버(240) 상에 마련되고 캠부재(230)와 접촉되어 탄성부재(250)의 힘을 캠부재(230)에 전달하는 구성으로 가압부(244)가 캠부재(230)와 접하는 지점이 캠부재(230)의 접촉부(234)가 될 수 있다.That is, the pressing unit 244 is provided on the lever 240 and in contact with the cam member 230 to transmit the force of the elastic member 250 to the cam member 230, the pressing unit 244 is a cam member The contact point 230 may be the contact portion 234 of the cam member 230.
제 1구간(A)과 제 2구간(C) 및 제 3구간(B)은 각각 다른 곡률을 포함하도록 마련될 수 있다. 도 7에 도시된 바와 같이 제 1구간(A)의 곡률 중심을 PA, 제 2구간(C)의 곡률 중심을 PC, 제 3구간(B)의 곡률 중심을 PB라고 할 때, 각각의 구간의 곡률 중심이 모두 다른 위치에 배치됨을 알 수 있다.The first section A, the second section C, and the third section B may be provided to include different curvatures, respectively. As shown in FIG. 7, when the center of curvature of the first section A is PA, the center of curvature of the second section C is PC, and the center of curvature of the third section B is PB, It can be seen that the centers of curvature are all located at different positions.
각각의 구간(A,B,C)가 다른 곡률을 가지고 형성됨에 따라 접촉부(234)가 각각의 구간(A,B,C)에 배치되면서 가압부(244)에 의해 전해지는 F1의 힘의 방향이 다양하게 바뀔 수 있다. 자세하게는 제 3구간(B)이 가지는 곡률은 제 1구간(A) 또는 제 2구간(C)이 가지는 곡률보다 크게 마련될 수 있고, 제 1구간(A)이 가지는 곡률은 제 2구간(C) 또는 제 3구간(B)이 가지는 곡률보다 작게 형성될 수 있다. 이는 후술할 제 1토크(T1)의 크기를 결정하는 중요한 요소인데 이에 대하여는 후술한다.As the sections A, B, and C are formed with different curvatures, the contact portion 234 is disposed in each of the sections A, B, and C, and the direction of the force of F1 transmitted by the pressing section 244. This can vary. In detail, the curvature of the third section B may be greater than the curvature of the first section A or the second section C, and the curvature of the first section A is the second section C. ) Or smaller than the curvature of the third section (B). This is an important factor for determining the size of the first torque T1 to be described later, which will be described later.
이하에서는 도어(100)가 완전 개방된 상태에서 폐쇄 방향으로 회전될 때, 캠부재(230)의 회전으로 가압부(244)가 캠부재(230)와 접하는 위치 및 이에 따라 형성되는 접촉부(234)의 위치에 대하여 설명한다.Hereinafter, when the door 100 is rotated in the closed direction in a fully open state, the position where the pressing portion 244 is in contact with the cam member 230 by the rotation of the cam member 230 and the contact portion 234 formed accordingly The position of will be described.
도 8a 내지 도 8d은 도어(100)의 회전에 따라 배치되는 캠부재(230)와 레버(240)를 도시하였는데 도시상의 편의를 위하여 도어(100)를 제외하였고 도어(100)와 대응되게 회전되는 샤프트(220)의 삽입부(222)만을 도시하였다.8A to 8D illustrate the cam member 230 and the lever 240 disposed according to the rotation of the door 100. For convenience of illustration, the door 100 is excluded and rotated to correspond to the door 100. Only the insert 222 of the shaft 220 is shown.
삽입부(222)가 배치되는 각도와 도어(100)가 배치되는 각도와 동일한 바 도 8a 내지 도 8d에서 도어(100)가 도시되지는 않았으나 삽입부(222)가 배치되는 각도를 도어(100)가 배치되는 각도로 설명한다.The angle at which the inserting portion 222 is disposed is the same as the angle at which the door 100 is disposed. Although the door 100 is not shown in FIGS. 8A to 8D, the angle at which the inserting portion 222 is disposed is defined as the door 100. It describes by the angle at which it is arranged.
도 8a에 도시된 바와 같이 접촉부(234)가 접촉구간(233) 상에 위치하는 AA점에 위치할 때 도어(100)가 완전 개방 위치에 배치될 수 있다. 또한 AA점은 제 1구간(A)이 시작되는 점으로 도어(100)가 폐쇄 방향으로 회전됨에 따라 캠부재(230)가 회전하고 도 8b에 도시된 바와 같이 가압부(244)와 접하는 접촉부(234)는 제 1구간(A)을 따라 접촉구간(233) 상에서 연속적으로 위치하게 된다.As shown in FIG. 8A, the door 100 may be disposed at the fully open position when the contact portion 234 is positioned at the AA point located on the contact section 233. In addition, the AA point is a point where the first section A starts, and as the door 100 is rotated in the closing direction, the cam member 230 rotates and the contact portion which contacts the pressing portion 244 as shown in FIG. 8B ( 234 is continuously positioned on the contact section 233 along the first section (A).
이 후 캠부재(230)의 회전으로 가압부(244)가 AB점과 접하여 접촉부(234)가AB점에 위치할 때 접촉부(234)는 제 1구간(A)을 지나 제 3구간(B)상에 배치되기 시작한다. 제 3구간(B)은 제 1구간(A)과 다른 곡률을 가지는 구간으로 사용자의 가압에 의해 도어(100)가 폐쇄 위치로 움직이게 되는데 이에 대하여는 후술한다.After that, when the contact portion 234 is positioned at the point AB because the pressing portion 244 contacts the AB point due to the rotation of the cam member 230, the contact portion 234 passes through the first section A and the third section B. To be placed on the bed. The third section B is a section having a curvature different from that of the first section A, and the door 100 moves to the closed position by the user's pressing, which will be described later.
계속되는 캠부재(230)의 회전으로 가압부(244)는 도 8c에 도시된 바와 같이 제 3구간(B)에 접하여 가압하다가 제 3구간(B)이 종료되고 제 2구간(C)이 시작되는 BC점에 접할 수 있다. 가압부(244)가 연속적으로 제 3구간(B)을 따라 제 2구간(C)을 접함에 따라 접촉부(234)도 연속적으로 제 3구간(B)을 따라 제 2구간(C) 상에 배치될 수 있다.As the cam member 230 continues to rotate, the pressing unit 244 is pressed against the third section B as shown in FIG. 8C, and the third section B ends and the second section C starts. You can touch BC. As the pressing part 244 continuously contacts the second section C along the third section B, the contact part 234 is continuously disposed on the second section C along the third section B. Can be.
도 8d에 도시된 바와 같이 캠부재(230)의 회전으로 가압부(244)는 BC점을 거쳐 제 2구간(C)과 연속적으로 접한 후 CC점에 접할 수 있게 되는데 가압부(244)가 CC점에 접하는 경우 도어(100)는 완전 폐쇄 위치에 배치되게 되어 도어(100)가 폐쇄되게 된다.As shown in FIG. 8D, the pressing unit 244 may be in contact with the CC point after the BC point is continuously contacted with the second section C through the rotation of the cam member 230. In the case of contact with the point, the door 100 is placed in a fully closed position, such that the door 100 is closed.
도어(100)의 폐쇄 상테에서 개방 상태로 회전하는 경우 가압부(244)는 상술한 순서와 반대로 접촉구간(233)가 연속적으로 접하면서 완전 개방 위치까지 배치될 수 있다.When rotating in the open state in the closed state of the door 100, the pressing unit 244 may be disposed to the fully open position while the contact section 233 is continuously in contact with the above-described order.
도어(100)는 개구(24)를 폐쇄하도록 개구(24)에 대한 각도가 0이되는 완전폐쇄 위치에서부터 개구(24)가 개방되도록 0도에서부터 개구(24)에 대한 각도가 증가하도록 시계 방향으로 회전되고 개구(24)에 대한 각도가 100도가 되었을 때 완전 개방될 수 있다. 다만 완전 개방 각도는 본 발명의 일 실시예에 한정되지 않고 100도 보다 낮은 각도로 형성되거나 높은 각도로 형성될 수 있다.The door 100 is clockwise to increase the angle to the opening 24 from 0 degrees such that the opening 24 opens from a fully closed position where the angle to the opening 24 becomes zero to close the opening 24. It may be rotated and fully open when the angle to the opening 24 is 100 degrees. However, the full opening angle is not limited to one embodiment of the present invention and may be formed at an angle lower than 100 degrees or at a high angle.
도 8a 및 도 8b와 같이 도어(100)가 시계방향으로 회전되어 완전 개방 위치에 인접하게 배치되는 경우 도어(100)는 제 1위치(a)에 도달될 수 있다. 도어(100)가 제 1위치(a)에 배치될 때, 접촉부(234)는 제 1구간(A) 상에 배치될 수 있다.8A and 8B, when the door 100 is rotated in a clockwise direction and disposed adjacent to the fully open position, the door 100 may reach the first position a. When the door 100 is disposed in the first position (a), the contact portion 234 may be disposed on the first section (A).
도어(100)가 제 1위치(a)에 배치되는 경우 사용자가 도어(100)를 시계 방향으로 가압하지 않아도 캠부재(230)에 가해지는 토크의 합력이 제 1토크(T1) 방향으로 형성되어 도어(100)의 개방 방향인 시계방향으로 회전될 수 있다.When the door 100 is disposed in the first position (a), even if the user does not press the door 100 in the clockwise direction, the torque of the torque applied to the cam member 230 is formed in the first torque T1 direction. It may be rotated in a clockwise direction in which the door 100 is opened.
자세하게는 접촉부(234)가 1구간(A)에 배치되어 형성되는 제 1토크(T1)가 제 2토크(T2)보다 강하게 캠부재(230)에 가해져서 캠부재(230)는 시계 방향으로 회전되고 이에 연동되어 도어(100)는 도 8b위치에서 도 8a의 위치로 사용자의 가압 없이 자동으로 회전될 수 있다.In detail, the first torque T1 formed by the contact portion 234 disposed in the first section A is applied to the cam member 230 more strongly than the second torque T2 so that the cam member 230 rotates clockwise. In conjunction with this, the door 100 may be automatically rotated from the position of FIG. 8B to the position of FIG. 8A without pressure of the user.
또한 도 8d와 같이 도어(100)가 반시계방향으로 회전되어 완전 폐쇄 위치에 인접하게 배치되는 경우 도어(100)는 제 2위치(c)에 도달될 수 있다. 도어(100)가 제 2위치(c)에 배치되는 경우 사용자가 도어(100)를 반시계 방향으로 가압하지 않아도 캠부재(230)에 가해지는 토크의 합력이 제 2토크(T2) 방향으로 형성되어 도어(100)의 폐쇄 방향인 반시계방향으로 회전될 수 있다.In addition, as shown in FIG. 8D, when the door 100 is rotated counterclockwise and disposed adjacent to the fully closed position, the door 100 may reach the second position c. When the door 100 is disposed in the second position (c), the torque of the torque applied to the cam member 230 is formed in the second torque T2 even when the user does not press the door 100 counterclockwise. It can be rotated in the counterclockwise direction which is the closing direction of the door 100.
자세하게는 접촉부(234)가 제 2구간(C)에 배치되어 형성되는 제 1토크(T1)가 제 2토크(T2)보다 약하게 캠부재(230)에 가해져서 캠부재(230)는 반시계 방향으로 회전되고 이에 연동되어 도어(100)가 제 2위치(c) 상에 배치될 경우 도 8d의 위치로 사용자의 가압 없이 자동으로 회전될 수 있다.In detail, the first torque T1 formed by the contact portion 234 disposed in the second section C is applied to the cam member 230 weaker than the second torque T2 so that the cam member 230 is counterclockwise. When the door 100 is disposed on the second position (c) in conjunction with this, it can be automatically rotated to the position of FIG. 8D without the user pressing.
또한 도 8c와 같이 도어(100)는 시계 방향 또는 반시계 방향으로 회전하다가 제 1위치(a)와 제 2위치(c) 사이에 마련되는 제 3위치(b)에 배치될 수 있다. 이 때 접촉부(234)는 제 3구간(B) 상에 위치하며, 도어(100)가 제 3위치(b)에 배치되는 경우 캠부재(230)에 가해지는 외부 합력이 0이 되는 위치를 포함하여 사용자가 도어(100)를 가압하지 않을 경우 도어(100)는 제 3위치(b) 상에 멈춤 상태로 배치될 수 있다.In addition, as illustrated in FIG. 8C, the door 100 may be disposed at a third position b provided between the first position a and the second position c while rotating clockwise or counterclockwise. At this time, the contact portion 234 is located on the third section (B), when the door 100 is disposed in the third position (b) includes a position where the external force applied to the cam member 230 is zero Therefore, when the user does not press the door 100, the door 100 may be disposed in a stopped state on the third position (b).
접촉구간(233)은 도어(100)가 상술한 바와 같이 제 1위치(a)와 제 2위치(c) 및 제 3위치(b)에 각각 배치될 수 있도록 제 1구간(A)과 제 2구간(C) 및 제 3구간(B)을 설정하고 가압부(244)가 각각의 구간(A,C,B)에 접할 때 도어(100)가 각각의 위치(a,c,b)에 배치될 수 있도록 접촉구간(233)을 구간에 따라 다르게 프로파일할 수 있다.The contact section 233 includes the first section A and the second section so that the door 100 may be disposed at the first position a, the second position c, and the third position b as described above. The section C and the third section B are set, and the door 100 is disposed at each position a, c, b when the pressing unit 244 is in contact with each section A, C, B. The contact section 233 may be profiled differently according to the section so as to be possible.
즉, 제 2토크(T2)의 경우 도어(100)의 자중은 정해진 재질에 의해 형성되는 도어(100)에 의해 회전 중에 변화가 없기 때문에 도어(100)의 무게중심(G)에서 중력가속도에 의해 형성되는 힘(F2) 값은 언제나 일정하다. 따라서 제 2토크(T2)는 도어(100)의 회전으로 회전축에서부터 무게중심(G)의 수직거리(r2)의 변화값에 따라 변화된다. 즉, 도어(100)는 회전되는 동안 무게중심(G)이 변화되지 않고, 도어(100)의 회전에 따라 무게중심(G)이 도어(100)의 회전 방향으로 일정하게 이동됨에 따라 무게중심(G)의 수직거리(r2)만 일정하게 변화되기 때문에 제 2토크(T2)는 대략 일정한 변화량을 가질 수 있다.That is, in the case of the second torque T2, the self-weight of the door 100 is not changed during rotation by the door 100 formed by a predetermined material, and therefore, due to gravity acceleration at the center of gravity G of the door 100. The force (F2) value formed is always constant. Therefore, the second torque T2 is changed according to the change value of the vertical distance r2 of the center of gravity G from the rotation axis by the rotation of the door 100. That is, the center of gravity G is not changed while the door 100 is rotated, and the center of gravity G is constantly moved in the rotation direction of the door 100 according to the rotation of the door 100. Since only the vertical distance r2 of G) is constantly changed, the second torque T2 may have a substantially constant change amount.
다만, 제 1토크(T1)의 경우 가압부(244)가 탄성부재(250)에 의해 형성되는 힘(F1)으로 접촉구간(233) 중 어느 일부에 접하게 되고 이 때 형성되는 F1의 크기와 F1이 향하는 방향에 대해 수직 방향으로의 거리(r1)에 따라 제 1토크(T1)의 크기가 변화된다.However, in the case of the first torque T1, the pressing part 244 is in contact with any part of the contact section 233 by the force F1 formed by the elastic member 250, and the size of F1 and F1 formed at this time. The magnitude of the first torque T1 changes according to the distance r1 in the vertical direction with respect to this facing direction.
자세하게는, 제 1토크(T1)를 발생시키는 F1 값은 탄성부재(250)의 압축력에 의해 형성되는 바 캠부재(230)의 회전에 따라 탄성부재(250)가 압축되는 정도가 달라지고 이에 따라 캠부재(230)가 회전되는 정도에 따라서 F1값이 변하게 된다.In detail, the F1 value for generating the first torque T1 may vary according to the rotation of the bar cam member 230 formed by the compressive force of the elastic member 250 and accordingly, The F1 value changes according to the degree of rotation of the cam member 230.
또한 가압부(244)를 통해 캠부재(230)로 전달되는 F1의 방향은 캠부재(230)의 곡면의 곡률에 따라 그 방향이 바뀌는 바 가압부(244)가 접촉구간(233) 중 어느 일부에 접하느냐에 따라 F1이 향하는 방향이 바뀌게 되고, 이에 따라 F1이 향하는 방향에 대한 수직 방향으로의 거리(r1)값도 변하게 된다.In addition, the direction of F1 transmitted to the cam member 230 through the pressing unit 244 is changed in accordance with the curvature of the curved surface of the cam member 230, the pressing unit 244 is any portion of the contact section 233 The direction in which F1 faces is changed depending on whether it is in contact with, and thus the value of the distance r1 in the vertical direction with respect to the direction in which F1 faces is also changed.
다르게 설명하자면, 접촉부(234)가 배치되는 곡면(232)의 곡률에 따라 F1의 방향이 변화되기 때문에 곡률에 따라서 r1값이 변하게 된다.In other words, since the direction of F1 changes according to the curvature of the curved surface 232 on which the contact portion 234 is disposed, the r1 value changes according to the curvature.
즉, 접촉구간(233)의 곡률을 변화시킴에 따라 제 1토크(T1)의 힘의 크기를 제어할 수 있고, 이에 따라 캠부재(230)의 곡면(232) 형상의 프로파일을 통해 제 1토크(T1)의 크기를 제어할 수 있다. 결론적으로 캠부재(230)의 프로파일을 통해 제 1토크(T1)와 제 2토크(T2)에 의해 캠부재(230)에 가해지는 토크 합력을 제어할 수 있다.That is, the magnitude of the force of the first torque T1 can be controlled by changing the curvature of the contact section 233, and accordingly the first torque through the profile of the curved surface 232 of the cam member 230. The size of T1 can be controlled. In conclusion, the torque force applied to the cam member 230 by the first torque T1 and the second torque T2 may be controlled through the profile of the cam member 230.
따라서 도어(100)가 제 1위치(a)에 배치될 시 가압부(244)는 제 1구간(A)에 접하게되고 이 때 제 2토크(T2)보다 제 1토크(T1)가 크도록 제 1구간(A)의 곡률을 프로파일하여, 도어(100)가 제 1위치(a)에 배치될 경우 자동으로 도어(100)가 개방방향으로 회전되게 할 수 있다.Therefore, when the door 100 is disposed in the first position (a), the pressing part 244 is in contact with the first section A, and the first torque T1 is larger than the second torque T2. By profiling the curvature of the first section A, the door 100 can be automatically rotated in the open direction when the door 100 is disposed in the first position (a).
또한 도어(100)가 제 2위치(c)에 배치될 시 가압부(244)는 제 2구간(C)에 접하게되고 이 때 제 2토크(T2)보다 제 1토크(T1)가 작도록 제 2구간(C)의 곡률을 프로파일하여, 도어(100)가 제 2위치(c)에 배치될 경우 자동으로 도어(100)가 폐쇄 방향으로 회전되게 할 수 있다.In addition, when the door 100 is disposed in the second position (c), the pressing unit 244 is in contact with the second section (C), and at this time, the first torque (T1) is smaller than the second torque (T2) The curvature of the two sections C may be profiled so that the door 100 may automatically rotate in the closing direction when the door 100 is disposed at the second position c.
또한 도어(100)가 제 3위치(b)에 배치될 시 가압부(244)는 제 3구간(B)에 접하게되고 이 때 캠부재(230)가 받는 외부 합력이 0이 되는 구간을 포함하도록 제 3구간(B)의 곡률을 프로파일하여, 도어(100)가 제 3위치(b)에 배치될 경우 사용자가 개방 방향 또는 폐쇄 방향으로 가압하지 않을 경우 멈춤 상태를 유지할 수 있다.In addition, when the door 100 is disposed in the third position (b), the pressing part 244 is in contact with the third section (B), and at this time includes an interval in which the external force received by the cam member 230 becomes zero. By profiling the curvature of the third section (B), when the door 100 is disposed in the third position (b), the user may maintain a stopped state when the user does not press in the opening direction or the closing direction.
특히, 도어(100)가 제 2위치(c)에 배치되는 경우 도어(100)가 자동으로 폐쇄 방향으로 회전되게 되는데 이 때 사용자의 손이 도어(100)와 캐비닛(10) 사이에 끼는 안전사고가 발생할 수 있다.In particular, when the door 100 is disposed in the second position (c), the door 100 is automatically rotated in the closing direction, at which time a user's hand is caught between the door 100 and the cabinet 10. May occur.
이를 방지하기 위하여 제 2구간(C)에서의 제 1토크(T1)와 제 2토크(T2)의 크기 차이가 급격하게 벌어지지 않도록 제 2구간(C)의 곡률을 프로파일할 수 있다.In order to prevent this, the curvature of the second section C may be profiled so that the magnitude difference between the first torque T1 and the second torque T2 in the second section C does not suddenly open.
즉, 가압부(244)가 제 3구간(B)을 따라 제 2구간(C) 상에 BC점과 인접할 때는 제 1토크(T1)와 제 2토크(T2)의 크기 차이를 작게하여 도어(100)가 천천히 폐쇄되도록 도어(100)의 폐쇄속도를 제어할 수 있다.That is, when the pressurizing portion 244 is adjacent to the BC point on the second section C along the third section B, the size difference between the first torque T1 and the second torque T2 is reduced. The closing speed of the door 100 may be controlled so that the 100 is closed slowly.
본 발명의 일 실시예에 의할 때, 도어(100)의 제1위치(a)와 제 3위치(b)는 도어(100)가 대략 75도에서 85도 사이에 배치될 때를 기준으로 나눠질 수 있다. 따라서 도어(100)가 개방되면서 대략 75도에서 85도 사이에 배치되는 경우 도어(100)는 도어(100)의 개방되는 방향으로 회전되어 자동으로 도어(100)가 100도를 이루는 위치까지 회전될 수 있다.According to an embodiment of the present invention, the first position (a) and the third position (b) of the door 100 are divided based on when the door 100 is disposed between approximately 75 and 85 degrees. Can lose. Therefore, when the door 100 is opened and disposed between approximately 75 degrees and 85 degrees, the door 100 is rotated in the opening direction of the door 100 to automatically rotate to the position where the door 100 forms 100 degrees. Can be.
또한 도어(100)의 제 2위치(c)와 제 3위치(b)는 도어(100)가 대략 25도에서 35도 사이에 배치될 때를 기준으로 나눠질 수 있다. 따라서 도어(100)가 폐쇄되면서 대략 25도에서 35도 사이에 배치되는 경우 도어(100)는 도어(100)의 폐쇄되는 방향으로 회전되어 자동으로 도어(100)가 0도를 이루는 위치까지 회전될 수 있다.In addition, the second position c and the third position b of the door 100 may be divided based on when the door 100 is disposed between approximately 25 degrees and 35 degrees. Therefore, when the door 100 is closed and disposed between approximately 25 degrees and 35 degrees, the door 100 is rotated in the direction in which the door 100 is closed to automatically rotate to the position where the door 100 is 0 degrees. Can be.
또한 도어(100)가 제 3위치(b)인 대략 25도에서 85도 사이에 배치될 때 도어(100)는 도어(100)의 사용자에 의한 가압이 없을 시 멈춤 상태를 유지할 수 있다.In addition, when the door 100 is disposed between approximately 25 degrees to 85 degrees in the third position (b), the door 100 may maintain a stopped state when there is no pressurization by the user of the door 100.
상술한 바와 같이 도어(100)가 배치되는 제 1,2,3위치(a,b,c)는 가압부(244)가 캠부재(230)의 접촉 구간(233) 중 어느 구간을 가압하느냐, 다르게 말하면 접촉부(234)가 제 1구간(A)과 제 2구간(C) 및 제 3구간(B) 중 어느 구간에 배치되느냐에 따라 달라질 수 있다.As described above, the first, second, third positions (a, b, c) of the door 100 is disposed in which section of the contact section 233 of the cam member 230 presses the pressing unit 244, In other words, the contact portion 234 may vary depending on which section of the first section A, the second section C, and the third section B is disposed.
또한 도어(100)의 제 1위치(a)와 제 3위치(b)는 대략 80도 전후로 구분되고 제 3위치(b)와 제 2위치(c)는 대략 30도 전후로 구분될 수 있는데 도어(100)의 제 1,2,3 위치(a,b,c)가 구분되는 각도는 캠부재(230)의 프로파일에 의해 달라질 수 있다. 이에 대해서는 도 9의 그래프를 통해 자세히 설명한다.In addition, the first position (a) and the third position (b) of the door 100 may be divided into approximately 80 degrees and the third position (b) and the second position (c) may be divided into approximately 30 degrees. The angles at which the first, second, third, and third positions (a, b, and c) of 100 are distinguished may vary according to the profile of the cam member 230. This will be described in detail with reference to the graph of FIG. 9.
도 9의 그래프 x축은 도어(100)가 완전 개방된 상태에서의 도어(100)의 각도가 100도일 때를 0, 완전 폐쇄 상태에서의 도어(100)의 각도가 0도일 때를 100으로 설정하였다. 즉, x축의 0에서 100으로 향하는 방향은 도어(100)가 완전 개방 상태에서 폐쇄 상태로 회전하는 방향이다.The graph x-axis of FIG. 9 is set to 0 when the angle of the door 100 is 100 degrees when the door 100 is fully open and 100 when the angle of the door 100 is 0 degrees in the fully closed state. . That is, the direction from 0 to 100 on the x axis is the direction in which the door 100 rotates from the fully open state to the closed state.
도어(100)가 폐쇄되는 방향으로 회전될 때 제 1토크(T1)와 제 2토크(T2)의 크기의 변화는 그래프와 같이 제 2토크(T2)는 도어(100)의 폐쇄 위치로 갈수록 지속적으로 증가하고, 제 1토크(T1)는 회전과 함께 그 크기가 증가하다가 제 2구간(C)에 배치되는 변환점(X1)을 지나면서 감소하게 된다. When the door 100 is rotated in the closing direction, the change in the magnitude of the first torque T1 and the second torque T2 continues as the second torque T2 continues toward the closed position of the door 100 as shown in the graph. The first torque T1 increases in size with rotation, and then decreases as it passes through the change point X1 disposed in the second section C.
반대로 도어(100)에 개방되는 방향으로 회전될 때 제 1토크(T1)와 제 2토크(T2)의 크기의 변화는 그래프와 같이 제 2토크(T2)는 개방 위치로 갈수록 지속적으로 감소하고 제 1토크(T1)는 폐쇄 시 회전과 함께 그 크기가 증가하다가 제 2구간(C)에 배치되는 변환점(X1)을 지나면서 감소하게 된다.On the contrary, when it is rotated in the direction of opening to the door 100, the change in the magnitude of the first torque T1 and the second torque T2 is continuously reduced to the open position as shown in the graph. One torque T1 increases in size with rotation upon closing and then decreases as it passes through the change point X1 disposed in the second section C.
이에 따라 그래프 상에서는 제 1토크(T1)가 제 2토크(T2)보다 큰 구간(XA), 제1,2토크(T1,T2)가 대응되는 구간(XB), 제 1토크(T1)가 제 2토크(T2)보다 작은 구간(XC)이 나눠지게 된다.Accordingly, in the graph, the section XA in which the first torque T1 is larger than the second torque T2, the section XB to which the first and second torques T1 and T2 correspond, and the first torque T1 are the first The section XC smaller than 2 torques T2 is divided.
상술한 바와 같이 그래프 상으로 제 1토크(T1)가 제 2토크보다(T2)보다 더 큰 구간(XA)은 접촉부(244)가 제 1구간(A) 상에 배치되는 구간이고, 제 1토크(T1)와 제 2토크(T2)가 대응되는 구간(XB)은 접촉부(244)가 제 3구간(B) 상에 배치되는 구간이고, 제 1토크(T1)가 제 2토크(T2)보다 더 작은 구간(XC)은 접촉부(244)가 제 2구간(C) 상에 배치되는 구간이다.As described above, the section XA in which the first torque T1 is larger than the second torque T2 on the graph is a section in which the contact portion 244 is disposed on the first section A, and the first torque. The section XB to which the T1 and the second torque T2 correspond is a section in which the contact portion 244 is disposed on the third section B, and the first torque T1 is greater than the second torque T2. The smaller section XC is a section in which the contact portion 244 is disposed on the second section C. FIG.
또한 그래프 상으로 제 1토크(T1)가 제 2토크보다(T2)보다 더 큰 구간(XA)에서는 도어(100)가 제 1위치(a) 상에 배치될 수 있고, 제 1토크(T1)와 제 2토크(T2)가 대응되는 구간(XB)에서는 도어(100)가 제 3위치(b) 상에 배치될 수 있고,제 1토크(T1)가 제 2토크(T2)보다 더 작은 구간(XC)에서는 도어(100)가 제 2위치(c)에 배치될 수 있다.In addition, in a section XA in which the first torque T1 is larger than the second torque T2 on the graph, the door 100 may be disposed at the first position a, and the first torque T1 may be used. In the section XB to which the second torque T2 corresponds, the door 100 may be disposed at the third position b, and the first torque T1 is smaller than the second torque T2. In XC, the door 100 may be disposed at the second position c.
상술한 바와 같이 캠부재(230)의 프로파일을 통하여 제 1토크(T1)와 제 2토크(T2)의 크기를 제어할 수 있기 때문에, 캠부재(230)는 도 9와 같은 형상의 그래프 값이 나오도록 프로파일될 수 있다. 즉, 캠부재(230)가 회전되는 동안 캠부재(230)는 XA구간, XB구간 및 XC구간을 포함하는 그래프가 형성되도록 프로파일될 수 있다.As described above, since the magnitudes of the first torque T1 and the second torque T2 can be controlled through the profile of the cam member 230, the cam member 230 has a graph value having a shape as shown in FIG. Can be profiled to come out. That is, while the cam member 230 is rotated, the cam member 230 may be profiled to form a graph including an XA section, an XB section, and an XC section.
캠부재(230)가 도 9에 도시된 그래프가 형성되도록 프로파일될 때, XA구간과 XB구간 및 XC구간을 구획하는 도어(100)의 각도는 임의적인 각도로 캠부재(230)의 프로파일에 따라 변화될 수 있다. When the cam member 230 is profiled to form the graph shown in FIG. 9, the angle of the door 100 partitioning the XA section, the XB section and the XC section is an arbitrary angle depending on the profile of the cam member 230. Can be changed.
즉, 접촉구간(233)의 곡률을 프로파일하여 각 위치(a,b,c)를 나눌 수 있는 도어(100)의 각도를 임의적으로 세팅할 수 있다. 따라서 제 1위치(a)와 제 3위치(b)를 구획하는 각도는 80도 외의 각도로 세팅될 수 있으며, 제 2위치(c)와 제 3위치(b)를 구획하는 각도는 30도 외의 각도로 세팅될 수 있다.That is, the curvature of the contact section 233 may be profiled to arbitrarily set the angle of the door 100 capable of dividing each position (a, b, c). Therefore, the angle dividing the first position (a) and the third position (b) may be set to an angle other than 80 degrees, and the angle dividing the second position (c) and the third position (b) is other than 30 degrees. Can be set at an angle.
캠부재(230) 접촉구간(233)의 각 구간(A,B,C)은 도어(100)의 제1위치(a), 2위치(c) 및 제 3위치(b)를 구획하는 요소인 도어(100)의 자중과 탄성부재(250)의 탄성력 및 각 구성과의 마찰력을 고려하여 각각의 곡률이 프로파일될 수 있다.Each section (A, B, C) of the cam member 230 contact section 233 is an element that partitions the first position (a), the second position (c) and the third position (b) of the door 100 Each curvature may be profiled in consideration of the self-weight of the door 100 and the elastic force of the elastic member 250 and the frictional force between the respective components.
캠부재(230)의 프로파일링에 의해 도어(100)의 제 1위치(a), 제 2위치(c) 및 제 3위치(b)를 나누는 각도가 달라짐에 따라 도 9에 도시된 제 1토크(T1)와 제 2토크(T2)의 그래프가 서로 접하는 점의 위치가 바뀔 수는 있으나, 제 1구간(A)과 제 2구간(C) 및 제 3구간(B) 상에서의 제 1토크(T1)와 제 2토크(T2) 의 상대적 크기는 도 9에 도시된 그래프와 유사하게 유지되도록 캠부재(230)가 프로파일될 수 있다.The first torque shown in FIG. 9 as the angle dividing the first position (a), the second position (c) and the third position (b) of the door 100 by profiling of the cam member 230 is changed. Although the position of the point where the graphs of T1 and the second torque T2 are in contact with each other may be changed, the first torque on the first section A, the second section C, and the third section B may be changed. The cam member 230 may be profiled so that the relative magnitude of T1) and the second torque T2 are maintained similar to the graph shown in FIG.
이하에서는 본 발명의 다른 일 실시예에 따른 캠부재(230)의 접촉구간(233')에 대하여 설명한다. 이하에서 설명하는 접촉구간(230') 이 외의 구성은 상술한 본 발명의 일 실시예에 따른 세탁기(1)의 구성과 동일한 바 중복되는 설명을 생략한다.Hereinafter, the contact section 233 'of the cam member 230 according to another embodiment of the present invention will be described. The configuration other than the contact section 230 ′ described below is the same as the configuration of the washing machine 1 according to the exemplary embodiment of the present invention, and thus a redundant description thereof will be omitted.
도 10에 도시된 바와 같이 본 발명의 다른 일 실시예에 따른 접촉구간(233')의 제 2구간(C')은 제 4구간(D')을 포함할 수 있다. 제 4구간(D')은 곡면(232)에 대해 오목하게 형성될 수 있다.As illustrated in FIG. 10, the second section C ′ of the contact section 233 ′ according to another embodiment of the present invention may include a fourth section D ′. The fourth section D 'may be concave with respect to the curved surface 232.
제 2구간(C)에 접촉부(234)가 배치될 시 도어(100)는 폐쇄되는 방향으로 회전되는데 도 9에 도시된 바와 같이 도어(100)가 폐쇄 방향으로 회전될수록 제 1토크(T1)와 제 2토크(T2)의 크기의 차이가 점점 커져 폐쇄 방향으로의 회전 속도가 커지게 된다.When the contact portion 234 is disposed in the second section C, the door 100 rotates in the closing direction. As shown in FIG. 9, the first torque T1 and the door 100 rotate in the closing direction. The difference between the magnitudes of the second torques T2 is gradually increased to increase the rotation speed in the closing direction.
즉, 제 2구간(C)이 시작되는 도어(100)의 각도는 대략 30도 전후로 도어(100)가 30도보다 낮은 각도로 배치될수록 더욱 빠르게 회전되어 폐쇄되는데 이는 도어(100)가 폐쇄될 시 사용자의 손가락이 도어(100)에 끼는 사고를 방지하기 위함이다.That is, the angle of the door 100 at which the second section C is started is rotated and closed faster as the door 100 is disposed at an angle lower than 30 degrees around 30 degrees. This is when the door 100 is closed. This is to prevent an accident that the user's finger is caught in the door 100.
다만, 실질적으로 사용자의 손가락이 도어(100)에 끼어 사고가 발생할 수 있는 도어(100)의 각도는 도어(100)의 폐쇄 위치와 매우 인접한 10도 내외라고 할 수 있다.However, the angle of the door 100, which may cause an accident due to a user's finger being caught in the door 100, may be said to be about 10 degrees very close to the closed position of the door 100.
도어(100)의 각도가 30도 이하로 형성되는 구간 중 실질적으로 사용자의 손가락이 끼어 부상이 발생하지 않는 구간인 10도 내지 30도 구간에서는 도어(100)가 천천히(여기서 천천히는 상술한 일 실시예에서 도어가 회전되는 속도) 회전될 필요가 없을 수 있다.In the section in which the angle of the door 100 is formed to be 30 degrees or less, the door 100 is slowly (here, slowly described above) in the section of 10 to 30 degrees, in which the user's fingers are substantially caught and no injury occurs. Speed at which the door is rotated) may not need to be rotated.
따라서 본 발명의 다른 일 실시예에 의한 캠부재(230)에는 접촉부(234)가 제 2구간(C')의 일부 구간에 배치되었을 때 도어(100)가 빠르게(여기서 빠르게는 일 실시예에서 도어가 회전하는 속도) 회전될 수 있도록 프로파일되는 제 4구간(D')이 마련될 수 있다.Therefore, when the contact portion 234 is disposed in a portion of the second section C 'in the cam member 230 according to another embodiment of the present invention, the door 100 is fast (where the door is fast in one embodiment). The fourth section D 'is profiled to be rotated.
자세하게는 제 2구간(C') 상에 제 4구간(D')이 포함될 수 있다. 도11b에 도시된 바와 같이 접촉부(234)가 제 2구간(C')상에서 오목하게 형성되는 제 4구간(D')에 도달될 경우 캠부재(230)가 레버(240)를 미는 힘이 급격하게 변하게 되는데 특히, 제 2구간(C')이나(도 11c) 제 3구간(B')에(도 11a) 비해 레버(240)를 미는 힘이 줄어들어 탄성부재(250)를 압축하는 힘이 줄어들고 이에 따라 가압부(244)가 캠부재(230)를 탄성 지지하는 힘이 줄어들어 제 1토크(T1)의 크기가 줄어들게 된다.In detail, the fourth section D 'may be included on the second section C'. As shown in FIG. 11B, when the contact portion 234 reaches the fourth section D 'that is formed concave on the second section C', the force for the cam member 230 to push the lever 240 is suddenly increased. In particular, the force pushing the lever 240 is reduced compared to the second section (C ') (Fig. 11c) or the third section (B') (Fig. 11a) to reduce the force to compress the elastic member 250 Accordingly, the force of the pressing unit 244 to elastically support the cam member 230 is reduced, thereby reducing the size of the first torque T1.
따라서 제 4구간(D') 상에 접촉부(234)가 배치되는 경우 도어(100)가 폐쇄 방향으로 회전 시 제 2토크(T2)와 제 1토크(T1)의 크기 차이가 급격하게(여기서 급격하게는 상술한 일 실시예에서 접촉부(234)가 제 2구간(C) 상에 배치될 때의 도어(100)가 폐쇄 방향으로 회전하면서 생기는 제 1토크(T1)와 제 2토크(T2)의 크기 차이) 발생할 수 있다.Therefore, when the contact portion 234 is disposed on the fourth section D ', when the door 100 rotates in the closing direction, a difference in magnitude between the second torque T2 and the first torque T1 is abrupt (here, abruptly). For example, in the above-described embodiment, the first torque T1 and the second torque T2 generated when the door 100 is rotated in the closing direction when the contact portion 234 is disposed on the second section C are provided. Size differences) may occur.
도 11c에 도시된 바와 같이 도어(100)가 계속 폐쇄 방향으로 회전되면서 접촉부(234)가 제 4구간(D')을 지나 제 2구간(B')에 배치될 경우 다시 제 1토크(T1)의 크기가 커져 도어(100)의 회전 속도가 느려질 수 있다.As shown in FIG. 11C, when the door 100 continues to rotate in the closing direction, when the contact portion 234 is disposed in the second section B 'through the fourth section D', the first torque T1 is again. The size of the larger the rotation speed of the door 100 may be slower.
이는 도 12에 도시된 그래프를 통해 확인할 수 있다. 접촉부(234)가 제 1구간(A)과 제 3구간(B)에 배치될 경우의 그래프는 XA', XB'구간을 형성할 수 있다. 도어(100)가 XA', XB' 구간과 대응되는 각도로 배치될 때에는 상술한 일 실시예에 의한 도 9의 그래프와 유사하게 도어(100)가 회전될 수 있다.This can be confirmed through the graph shown in FIG. 12. When the contact portion 234 is disposed in the first section A and the third section B, the graph may form sections XA 'and XB'. When the door 100 is disposed at an angle corresponding to the XA 'and XB' sections, the door 100 may be rotated similarly to the graph of FIG. 9 according to the above-described embodiment.
다만, 접촉부(234)가 제 2구간(C') 상에 배치될 경우 본 발명의 다른 일 실시예에 의한 그래프는 도어(100)가 폐쇄 방향으로 회전되면서 XC'구간 내에 XD'구간을 가지게 되는데 도 12에 도시된 바와 같이 XD' 구간은 제 1토크(T1)와 제 2토크(T2)의 크기가 크게 벌어지는 구간이고, 이에 따라 도어(100)가 XD'구간에 해당되는10도 내지 30도 각도에 배치될 때 폐쇄방향으로 빠르게 회전될 수 있다.However, when the contact portion 234 is disposed on the second section C ', the graph according to another embodiment of the present invention has the section XD' within the section XC 'as the door 100 rotates in the closing direction. As shown in FIG. 12, the XD 'section is a section in which the sizes of the first torque T1 and the second torque T2 are greatly enlarged, and thus the door 100 is in a range of 10 degrees to 30 degrees corresponding to the section XD'. When placed at an angle it can be quickly rotated in the closing direction.
도어(100)의 계속되는 폐쇄 방향으로의 회전 시 접촉부(234)는 제 2구간(B')에 배치되게 되고 이 때 제 1토크(T1)가 일시적으로 증가됨에 따라 접촉부(234)가 제 4구간(D')에 배치될 때보다 도어(100)의 회전 속도가 느려질 수 있다.When the door 100 is rotated in the continuous closing direction, the contact portion 234 is disposed in the second section B '. At this time, as the first torque T1 is temporarily increased, the contact portion 234 is in the fourth section. The rotation speed of the door 100 may be slower than when disposed at (D ′).
즉, 그래프 상으로 XD'구간이 아닌XC'구간은 도어(100)가 0도 내지 10도 사이의 각도를 가지고 있을 때인데, XD'구간에서 XC'구간으로 바뀌면서 제 1토크(T1)의 크기가 상승함에 따라 도어(100)가 대략 10도의 각도로 배치될 때는 도어(100)가 10도 내지 30도의 각도로 배치될 때보다 더 느리게 회전될 수 있어 사용자의 손가락이 도어(100)에 끼는 사고를 방지할 수 있다.That is, the XC 'section, not the XD' section, is when the door 100 has an angle between 0 degrees and 10 degrees, and the size of the first torque T1 is changed from the XD 'section to the XC' section. When the door 100 is disposed at an angle of approximately 10 degrees as the door rises, the door 100 may be rotated more slowly than when the door 100 is disposed at an angle of 10 to 30 degrees, so that a user's finger is caught in the door 100. Can be prevented.
이 후 도어(100)가 폐쇄 방향으로 더 회전되면서 제 1토크(T1)의 크기가 줄어들고 이에 따라 도어(100)가 빠르게 회전되어 도어(100)가 완전 폐쇄될 수 있다.Thereafter, as the door 100 is further rotated in the closing direction, the size of the first torque T1 is reduced, and thus the door 100 is rapidly rotated to completely close the door 100.
본 발명의 다른 일 실시예와 달리 제 4구간(D')은 곡면(322)에 대해 볼록하게 돌출되는 형상으로도 마련될 수 있다. 제 4구간(D')이 볼록하게 마련될 경우 제 1토크(T1)가 오히려 더 커지면서 도어(100)의 회전 속도가 더 느려질 수 있다.Unlike another embodiment of the present invention, the fourth section D 'may be provided in a shape that protrudes convexly with respect to the curved surface 322. When the fourth section D 'is convex, the first torque T1 may become larger and the rotation speed of the door 100 may be slower.
필요에 따라 캠부재(230)의 제 4구간(D')을 프로파일하여 도어(100)가 더 빨라지게 또는 도어(100)가 더 느려지게 회전되도록 할 수 있다. 또한 접촉구간(233) 상에 제 4구간(D') 이 외 추가적으로 제 1토크(T1)와 제 2토크(T2)의 힘의 크기를 제어하는 제 5구간이 배치될 수 있어 도어(100)의 회전 속도 및 방향을 제어할 수 있다.If necessary, the fourth section D 'of the cam member 230 may be profiled so that the door 100 may be rotated faster or the door 100 may be slower. In addition, a fourth section for controlling the magnitude of the force of the first torque T1 and the second torque T2 in addition to the fourth section D 'may be disposed on the contact section 233. It is possible to control the rotation speed and direction of the.
즉, 캠부재(230)의 접촉구간(233)의 형상을 다양하게 프로파일하여 도어(100)의 회전 속도와 방향을 자유롭게 제어할 수 있다. 이에 따라 캠부재(230)와 캠부재(230)에 직접 접하는 레버(240) 및 레버(240)를 탄성지지하는 탄성부재(250)의 구성만으로도 도어(100)를 용이하게 제어할 수 있다.That is, by varying the shape of the contact section 233 of the cam member 230, the rotational speed and direction of the door 100 can be freely controlled. Accordingly, the door 100 may be easily controlled only by the configuration of the cam member 230, the lever 240 directly contacting the cam member 230, and the elastic member 250 elastically supporting the lever 240.
이하에서는 본 발명의 다른 일 실시예에 따른 힌지유닛(200')에 대하여 설명한다. 이하에서 설명하는 레버(240') 또는 댐퍼(260) 이 외의 구성은 상술한 본 발명의 일 실시예에 따른 세탁기(1)의 구성과 동일한 바 중복되는 설명을 생략한다.Hereinafter, a hinge unit 200 'according to another embodiment of the present invention will be described. The configuration other than the lever 240 ′ or the damper 260 described below is the same as the configuration of the washing machine 1 according to the exemplary embodiment of the present invention, and thus a redundant description thereof will be omitted.
도 13 및 도 14에 도시된 바와 같이 힌지유닛(200')은 본 발명의 일 실시예에 의한 힌지유닛(200)과 달리 추가적으로 댐퍼(260)를 포함할 수 있다.As shown in FIGS. 13 and 14, the hinge unit 200 ′ may additionally include a damper 260 unlike the hinge unit 200 according to the exemplary embodiment of the present invention.
댐퍼(260)는 레버(240')의 일측에 배치될 수 있다. 자세하게는 댐퍼(260)는 힌지유닛(200')의 일측에 마련되는 삽입 홈(245)에 삽입되어 레버(240')의 일측에 배치되면서, 탄성부재(250)의 내측에 삽입되도록 배치될 수 있다.The damper 260 may be disposed on one side of the lever 240 '. In detail, the damper 260 is inserted into the insertion groove 245 provided at one side of the hinge unit 200 'and disposed at one side of the lever 240', and may be disposed to be inserted into the elastic member 250. have.
본 발명의 일 실시예에 따른 레버(240)의 경우 가이드부(241)이 마련되나 본 발명의 다른 일 실시예에 따른 레버(240')는 가이드부(241)가 배치되는 위치에 댐퍼(260)가 마련될 수 있다.In the case of the lever 240 according to an embodiment of the present invention, the guide part 241 is provided, but the lever 240 'according to another embodiment of the present invention has a damper 260 at a position where the guide part 241 is disposed. ) May be provided.
삽입 홈(245)의 테두리 측에는 지지부(242')가 마련되어 탄성부재(250)가 지지부(242')에 지지되어 레버(240')로 탄성력이 전달될 수 있다. 탄성부재(250)가 지지부(242')에 지지되면서 탄성부재(250) 내측으로 댐퍼(260)가 삽입되는 바 댐퍼(260)는 탄성부재(250)가 레버(240')에서 이탈되지 않고 압축 신장될 수 있도록 탄성부재(250)를 가이드 할 수 있다.A support part 242 ′ is provided at the edge of the insertion groove 245 so that the elastic member 250 is supported by the support part 242 ′ so that an elastic force may be transmitted to the lever 240 ′. The elastic member 250 is supported by the support part 242 'so that the damper 260 is inserted into the elastic member 250. The damper 260 compresses the elastic member 250 without being separated from the lever 240'. The elastic member 250 may be guided to extend.
댐퍼(260)는 댐퍼 하우징(261)과 댐퍼 하우징(261) 내부에 마련되는 실린더실(262)과 실린더실(262) 내부를 왕복 운동하는 로드(263)를 포함할 수 있다. 실린더실(262) 내부에는 로드(263)의 왕복 운동을 제한하도록 마련되는 오일, 오일이 이동되는 오리피스, 공기실 등이 구성을 추가적으로 포함하나 설명의 편의상 이와 같은 도면의 표기는 생략한다.The damper 260 may include a damper housing 261, a cylinder chamber 262 provided inside the damper housing 261, and a rod 263 reciprocating inside the cylinder chamber 262. The cylinder chamber 262 further includes a configuration in which an oil provided to limit the reciprocating motion of the rod 263, an orifice through which the oil is moved, an air chamber, and the like, is omitted for the convenience of description.
댐퍼(260)는 도어(100)가 폐쇄될 시 도어(100)와 연동되어 회전되는 캠부재(230)에 의해 레버(240')가 하우징(210)의 지지면(212) 측으로 선형 운동될 시 레버(240')의 지지면(212) 측을 향하는 선형 운동의 속도를 감쇄시키는 댐핑을 할 수 있다.The damper 260 is linearly moved toward the support surface 212 of the housing 210 by the cam member 230 which is rotated in conjunction with the door 100 when the door 100 is closed. Damping may be performed to attenuate the speed of the linear movement toward the support surface 212 side of the lever 240 '.
즉, 상술한 바와 같이 캠부재(230)의 곡면(232)을 프로파일링하여 토크값(T1,T2)를 설정하여 도어(100)의 폐쇄 시 사용자가 도어(100)와 캐비닛(10) 사이에 손가락이 끼는 것을 방지하면서, 추가적으로 댐퍼(260)를 추가하여 도어(100)의 폐쇄되는 속도를 추가적으로 저감시켜 안전 사고를 더욱 예방할 수 있다. 또한 도어(100)가 최종적으로 캐비닛(10)의 개구(24)를 폐쇄할 시 도어(100)의 폐쇄속도가 댐퍼(260)에 의해 자연스럽게 저감되어 사용자가 도어(100)를 닫힘이 부드럽고 안정적으로 수행될 수 있다.That is, as described above, the curved surface 232 of the cam member 230 is profiled to set torque values T1 and T2 so that the user may close the door 100 and the cabinet 10 when the door 100 is closed. While preventing fingers from being caught, an additional damper 260 may be added to further reduce the closing speed of the door 100 to further prevent a safety accident. In addition, when the door 100 finally closes the opening 24 of the cabinet 10, the closing speed of the door 100 is naturally reduced by the damper 260 so that the user can close the door 100 smoothly and stably. Can be performed.
자세하게는 댐퍼(260)는 도 15a에 도시된 바와 같이 레버(240')의 가압부(244)가 제1구간(A)과 접해있을 시에는 하우징(210)의 지지면과 접촉하지 않아 댐핑이 되지 않는다. 즉, 가압부(244)가 제 1구간(A)과 접해있을 시 도어(100)는 개방되는 구간에 배치되어 도어(100)의 회전이 댐퍼(260)에 의해 제한되지 않는다.In detail, the damper 260 does not come into contact with the support surface of the housing 210 when the pressing part 244 of the lever 240 ′ is in contact with the first section A, as shown in FIG. 15A. It doesn't work. That is, when the pressing unit 244 is in contact with the first section A, the door 100 is disposed in an open section, and the rotation of the door 100 is not limited by the damper 260.
도어(100)가 개방 상태에서 폐쇄되는 방향으로 회전될 경우 캠부재(230)가 도어(100)에 연동되어 회전됨에 따라 가압부(244)가 접하는 지점은 순차적으로 제 1구간(A)에서 제 3구간(B), 제 3구간(B)에서 제 2구간(C)으로 변화될 수 있다.When the door 100 is rotated in the closed direction in the open state, as the cam member 230 is rotated in conjunction with the door 100, the point where the pressing part 244 comes into contact with each other is sequentially formed in the first section A. FIG. The third section B and the third section B may be changed into the second section C. FIG.
가압부(244)가 제 3구간(B) 중 어느 일 지점과 접하고 있는 중(대략 도어(100)의 개방 각도가 45도에서 100도 내외 일 시) 도어(100)가 폐쇄되는 방향으로 더 회전되어 도어(100)의 개방 각도가 줄어들게 될 시, 회전되는 캠부재(230)에 의해 곡면(232)은 레버(240')를 가압하고 이에 따라 레버(240')가 지지면(212)측으로 더 이동될 수 있다.While the pressing unit 244 is in contact with one point of the third section B (approximately when the opening angle of the door 100 is about 45 to 100 degrees), the door 100 is further rotated. When the opening angle of the door 100 is reduced, the curved surface 232 presses the lever 240 'by the cam member 230 which is rotated, and thus the lever 240' is further toward the support surface 212. Can be moved.
이에 따라 댐퍼(260)의 로드(263)가 하우징(210)의 일측과 접하게 되고, 로드(263)의 접촉면(263a)이 하우징(210)의 지지면(212)과 접하면서 댐핑이 발생하여 레버(240')가 지지면(212)측으로 이동되는 것을 제한할 수 있다.Accordingly, the rod 263 of the damper 260 comes into contact with one side of the housing 210, and the damping occurs while the contact surface 263a of the rod 263 comes into contact with the support surface 212 of the housing 210. It is possible to limit the movement of 240 ′ toward the support surface 212.
로드(263)의 접촉면(263a)과 지지면(212)이 접할 시의 도어(100)의 개방각도는 바람직하게는 45도 내외일 수 있다. 다만, 이에 한정되지 않고 도어(100)의 크기 또는 탄성부재(250)의 탄성력 등에 따라 접촉면(263a)과 지지면(212)이 접할 시의 도어(100)의 개방 각도는 달라질 수 있다.When the contact surface 263a of the rod 263 and the support surface 212 are in contact with each other, the opening angle of the door 100 may be about 45 degrees. However, the present invention is not limited thereto, and the opening angle of the door 100 when the contact surface 263a and the support surface 212 are in contact with each other may vary depending on the size of the door 100 or the elastic force of the elastic member 250.
접촉면(263a)과 지지면(212)이 접한 후 도어(100)가 폐쇄되는 방향으로 회전될 시 댐퍼(260)에 의해 레버(240')의 병진운동이 제한되어 도어(100)가 상대적으로 천천히 회전될 수 있다. When the contact surface 263a and the support surface 212 are in contact with each other and the door 100 is rotated in a direction in which the door 100 is closed, the translational movement of the lever 240 'is limited by the damper 260, so that the door 100 is relatively slow. Can be rotated.
즉, 도 15c에 도시되는 바와 같이 도어(100)가 로드(263)의 접촉면(263a)과 지지면(212)이 접한 상태에서 폐쇄되는 방향으로 회전되는 경우, 로드(263)가 실린더실(262) 내측에서 선형 운동을 하면서 레버(240')에 대한 댐핑이 발생할 수 있다.That is, as shown in FIG. 15C, when the door 100 is rotated in a direction in which the contact surface 263a and the support surface 212 of the rod 263 are in contact with each other, the rod 263 is the cylinder chamber 262. Damping to the lever 240 'may occur while linearly moving inside.
따라서, 도어(100)의 개방 각도가 45도 이하인 상태에서 도어(100)가 폐쇄 방향으로 회전될 시 댐퍼(260)의 댐핑이 발생되어 도어(100)가 폐쇄되는 속도가 저감될 수 있다.Therefore, when the door 100 is rotated in the closing direction in a state in which the opening angle of the door 100 is 45 degrees or less, damping of the damper 260 occurs, and thus the speed at which the door 100 is closed may be reduced.
본 발명의 일 실시예에 의할 시 레버(240)가 곡률을 달리하는 제 1구간(A)과 제 2구간(C) 및 제 3구간(B)을 각각 접하면서 제 1토크(T1)값을 조정할 수 있는데, 본 발명의 다른 일 실시예와 같이 조정된 제 1토크(T1) 값에 추가적으로 댐퍼(260)가 배치되어 레버(240')에 의해 도어(100)에 형성되는 토크(T1) 값이 본 발명의 일 실시예에 따라 조정된 제 1토크(T1)과 다르게 형성될 수 있다.According to an embodiment of the present invention, the lever 240 has a first torque value T1 while contacting the first section A, the second section C, and the third section B, each of which has a different curvature. In addition, the damper 260 is disposed in addition to the adjusted first torque T1 value as in another embodiment of the present invention, and the torque T1 formed in the door 100 by the lever 240 '. The value may be formed differently from the first torque T1 adjusted according to the embodiment of the present invention.
즉, 본 발명의 일 실시예에 의할 시 제 3구간(B)에서 제 1토크(T1)와 제 2토크(T2)가 동일한 값을 가지게 되는 지점이 형성되어 도어(100)가 멈춤 상태를 유지할 수 있으나, 본 발명의 다른 일 실시예에 의할 시 댐퍼(260)의 댐핑에 의해 제 1토크(T1)와 제 2토크(T2)가 동일한 값을 가지게 되는 지점이 제 3구간(B)이 아니라 제 2구간(B)에 형성될 수 있다. That is, according to an embodiment of the present invention, a point where the first torque T1 and the second torque T2 have the same value in the third section B is formed so that the door 100 stops. According to another embodiment of the present invention, the third section B may have a point at which the first torque T1 and the second torque T2 have the same value due to damping of the damper 260. It may not be formed in the second section (B).
또한 본 발명의 일 실시예에 의할 시 제 1토크(T1)와 제 2토크(T2)가 동일한 값을 가지게 되는 지점이 일정 구간 지속될 수 있으나, 본 발명의 다른 일 실시예에 의할 시 제 1토크(T1)와 제 2토크(T2)가 동일한 값을 가지게 지점이 일정 구간 지속되지 않고 일 지점으로 형성될 수 있다.In addition, the point where the first torque T1 and the second torque T2 have the same value may be sustained for a certain period when according to an embodiment of the present invention, but according to another embodiment of the present invention The point may be formed as one point without lasting a predetermined period such that the first torque T1 and the second torque T2 have the same value.
