Description

플로어 힌지의 피스톤 변형방지 구조{STRUCTURE FOR PROTECTING PISTON DEFORMATION OF FLOOR HINGE}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a piston hinge,

본 발명은 여닫이문용 플로어 힌지에 관한 것으로서, 더욱 상세하게는 선출원의 구조개선에 의해 여닫이문의 잦은 개폐동작에 따른 피스톤의 변형을 방지하여 수평의 진퇴운동으로 인한 실린더실의 편중마모 최소화로 사용수명을 최대한 보장할 수 있어 제품의 신뢰성이 보장되는 플로어 힌지의 피스톤 변형방지 구조에 관한 것이다.The present invention relates to a floor hinge for a hinged door, and more particularly, to a hinged floor hinge for a hinged door, which prevents the piston from being deformed by frequent opening and closing operations of the hinged door, To a structure for preventing deformation of a piston of a floor hinge in which the reliability of the product can be ensured as much as possible.

일반적으로 밀거나 당김에 의한 회전 개폐되는 여닫이문은 회전에 따른 축기능을 하는 플로어 힌지가 여닫이문의 일측의 하측에 구비되고, 대응한 상측에는 회전축으로 구비되어 회전이 지지된다.Background of the Invention [0002] Generally, a hinged door that is opened or closed by being pushed or pulled is provided on a lower side of one side of a hinged door, and a rotary shaft is provided on a corresponding upper side thereof.

이러한 플로어 힌지는 여닫이문의 개폐 안전을 위해 급격하게 열거나 닫히는 속도의 감속 완충을 위해 완충기능이 구비되어 있다.These floor hinges are equipped with buffering function to reduce the opening speed of the hinged doors or to reduce the speed of closing the door hinges.

종래에도 다양한 기술의 플로어 힌지가 개시되어 있으나, 일 예로 특허문헌 1에서는 케이싱 내부에 수직방향으로 힌지축이 축조립으로 입설되어 있으며, 여닫이문과 결합한 힌지축의 회전에 의한 일체구조의 캠의 회전으로 피스톤이 종속적으로 후진하면서 상기 캠의 90도 방향으로 형성된 일측 캠홈이 피스톤의 일측 롤러에 맞결합되면서 여닫이문의 개방상태를 고정하고, 상기 여닫이문을 닫을 경우에는 피스톤의 일측에 설치된 압축스프링이 탄성력에 의해 원상태로 밀어 타측 캠홈에 롤러를 맞결합에 의해 고정하도록 되어 있다.For example, in the conventional art, a hinge shaft is vertically arranged inside a casing by shaft assembly, and the rotation of the hinge shaft combined with the hinged door causes rotation of the cam of the integral structure, And the one side cam groove formed in the direction of 90 degrees of the cam is engaged with one roller of the piston to fix the opening state of the hinged door. When the hinged door is closed, the compression spring provided on one side of the piston is biased by the elastic force So that the roller is fixed to the other cam groove by the engagement.

물론, 이러한 동작시에 케이싱의 내부인 작동공간(실린더실)에 충전된 유체에 의해 피스톤의 진퇴운동이 감속 완충되면서 개폐동작이 제공되고 상기 케이싱의 작동공간(실린더실)의 축소에 의해 완충정도를 조절할 수 있다.Of course, during this operation, the piston moves forward and backward while the piston moves back and forth by the fluid filled in the working space (cylinder chamber), which is the interior of the casing, and the operating space Can be adjusted.

이러한 특허문헌 1에는 종래의 문제점인 플로어 힌지는 구조를 단순화하여 부품수의 최소화 및 조립성을 개선의 장점을 제공하고 있다.In this patent document 1, the floor hinge, which is a conventional problem, has the advantage of simplifying the structure and minimizing the number of components and improving the assemblability.

그러나 상기한 특허문헌 1은 도 1에 도시된 것과 같이, 케이싱(10)과 피스톤(30), 상기 피스톤(30)에 조립되는 힌지축(20)의 조립구조의 특성상 케이싱(10)의 작동공간에 수용되는 피스톤(30)에는 수직방향으로 조립되는 상기 힌지축(20)에 일체화된 캠(21)의 작동을 위해 캠수용공간(31)은 반드시 상부개방부(A)를 형성하여 조립된 구조를 취하고 있다.1, the structure of the casing 10, the piston 30, and the hinge shaft 20 assembled to the piston 30, The cam accommodating space 31 must be formed with an upper opening A for the operation of the cam 21 integrated with the hinge shaft 20 assembled in the vertical direction in the piston 30 accommodated in the hinge shaft 20, .

따라서 특허문헌 1은 힌지축(20)에 조립되는 여닫이문의 반복적인 개폐동작에 따른 반복적인 하중회전에 미치게 되어 상기 피스톤(30)은 진퇴운동에 따른 실린더실(작동공간)의 상대적인 전, 후방 측의 반발 유압에 의해 캠수용공간(31)의 상부 개방부가 오그라드려는 변형력에 의해 피스톤의 전방 상단부와 후방의 상단부 측이 실린더실(작동공간)을 깍아먹는 편중마모가 발생되어 시간이 갈수록 피스톤의 진퇴운동에 따른 완충감속 작동의 작동저하로 사용수명을 보장하지 못하는 단점이 있었다. Therefore, the patent document 1 is subjected to repetitive load rotation due to repetitive opening and closing operations of the hinge shaft assembled to the hinge shaft 20, so that the piston 30 moves forward and backward relative to the cylinder chamber (working space) The operating force of the piston 31 is transmitted to the piston 31 via the piston 31. The piston 31 is reciprocated in the axial direction of the piston 31, There is a disadvantage in that the service life can not be guaranteed due to the operation deterioration of the buffering deceleration operation due to the back and forth movement.

그리고 특허문헌 2는 특허문헌 1의 구조를 크게 변형하지 않고 케이싱(10)에 여닫이문을 조립하고, 힌지축(20)을 바닥과 축 조립하는 설치방향을 반대로 취하고 있으나, 특허문헌 1과 같은 피스톤의 변형력에 따른 케이싱의 작동공간(실린더실)의 편중마모가 발생하는 동일한 문제점이 있었다.In addition, Patent Document 2 adopts a reversing direction in which the hinged shaft 20 is assembled to the floor with the hinged shaft 20 in the opposite direction, while the hinged door is assembled to the casing 10 without significantly changing the structure of Patent Document 1. However, (Cylinder chamber) according to the deformation force of the casing.

본 발명은 상기와 같은 선원기술이 갖는 문제점을 해소하고자 안출된 것으로서, 여닫이문의 하중 회전을 지지하는 힌지축 캠의 회전으로 진퇴작동하는 피스톤의 캠수용공간의 상부개방부가 상대적으로 작용하는 반발유압에 의해 오그라드는 변형을 방지하여 케이싱의 작동공간 편중마모를 방지하여 원활한 감속완충의 작동 수명을 극대화하는 플로어 힌지의 피스톤 변형방지 구조를 제공하는 것을 목적으로 하고 있다.SUMMARY OF THE INVENTION It is an object of the present invention to provide a hermetically sealed hermetically sealed container having a hermetically sealed container, And it is an object of the present invention to provide a structure for preventing deformation of a piston of a floor hinge, which prevents deformation of the casing by preventing deformation of the casing, thereby maximizing the working life of the smooth deceleration buffer.

상기 목적을 달성하기 위한 본 발명에 의한 플로어 힌지의 피스톤 변형방지 구조는,According to an aspect of the present invention, there is provided a structure for preventing deformation of a piston of a floor hinge,

피스톤의 상부 개방부에 변형방지구를 조립하여 피스톤의 전진운동에 따른 상대적 작용의 반발유압에 의해 상부 개방부 측이 오그라드는 변형을 방지하여 피스톤의 전,후방측의 상단부분이 케이싱의 실린더실의 편중마모를 차단함으로 해서 피스톤에 의해 구획된 양측의 실린더실(작동공간)의 반발유압작동의 균형으로 피스톤의 완충감속운동의 정확한 작동을 제공하도록 구성한 것을 특징으로 한다.The deformation preventing portion is assembled to the upper opening portion of the piston to prevent the upper opening portion from being deformed due to the repulsive hydraulic pressure of the relative action due to the forward movement of the piston so that the upper end portions of the front and rear sides of the piston are connected to the cylinder chamber (Operation space) of the cylinder chambers (working chambers) on both sides partitioned by the pistons, thereby providing an accurate operation of the cushioning reduction and deceleration motion of the piston.

여기서, 상기 변형방지구는 상기 피스톤의 상부 개방부의 길이에 맞는 길이로서 일측이 개방된 U자형 개방끼움홈으로 힌지축의 외주면에 끼움조립되는 것을 특징으로 한다.In this case, the deformation preventing hole is a U-shaped open groove having a length corresponding to the length of the upper opening of the piston and is fitted on the outer circumferential surface of the hinge shaft with one side opened.

그리고 상기 변형방지구는 피스톤의 상부개방부의 양측에서 힌지축의 캠과 접동하는 롤러의 축에 조립되는 스냅링으로 받침 지지되어 힌지축의 캠과 롤러의 회전간섭이 없도록 설치되는 것을 특징으로 한다.The deformation preventing member is mounted on both sides of the upper opening of the piston so as to be supported by a snap ring assembled to the shaft of the roller sliding on the cam of the hinge shaft so that rotation interference of the cam and the roller of the hinge shaft is prevented.

본 발명에 의하면, 여닫이문의 반복적인 개폐동작에도 피스톤의 수평 진퇴운동으로 피스톤 및 실린더의 실리더실(작동공간)의 편중마모를 최대한 방지하여 플로어힌지의 정확한 작동수명을 최대한 연장하는 효과를 지속할 수 있으며, 단순구조의 개선으로 제조원가를 크게 증가하지 않고 소비자에게 공급할 수 있어 제품의 신뢰성이 보장되는 이점이 있다.According to the present invention, even when the opening / closing operation of the hinged door is repeatedly performed, the horizontal movement of the piston makes it possible to prevent the double threaded wear of the cylinder thread (working space) of the piston and the cylinder as much as possible, And it is advantageous in that the reliability of the product can be assured because the improvement of the simple structure enables the supply to the consumer without increasing the manufacturing cost greatly.

이하, 첨부되는 도면과 참조하여 본 발명에 대하여 상세히 설명한다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

즉, 본 발명은 도 2 내지 도 3에 도시된 것과 같이, 특허문헌 1에서 개시된 실린더실의 작동공간(110)을 갖는 케이싱(100), 힌지축(200) 및 힌지축 캠(210), 캠 수용공간(310)을 갖도록 상부 개방부(A)를 갖는 피스톤(300), 상기 피스톤(300)의 일측에서 탄력지지하는 압축스프링(400)의 구성요소를 포함한다.2 to 3, the present invention includes a casing 100, a hinge shaft 200 and a hinge shaft cam 210 having a working space 110 of a cylinder chamber disclosed in Patent Document 1, A piston 300 having an upper opening A to have a receiving space 310 and a component of a compression spring 400 which elastically supports at one side of the piston 300.

상기 케이싱(100)은 상기 작동공간(110)에 연통하는 힌지공(120)이 가공되고, 상기 작동공간(110)은 양측에서 나사조립되는 밀폐캡(130,130)에 의해 기밀된다.The casing 100 is formed with a hinge hole 120 communicating with the operation space 110 and the operation space 110 is airtight by the sealing caps 130 and 130 screwed on both sides.

그리고 힌지공(120) 역시, 상기 힌지축(200)의 외주면을 축기밀한 상태로 나사조립되는 밀폐캡(230)에 의해 기밀된다.The hinge hole 120 is also hermetically sealed by a sealing cap 230, which is screwed into the outer peripheral surface of the hinge shaft 200 in an axially airtight manner.

따라서 상기 작동공간에는 완충을 위해 충전되는 유체의 외부누설이 없는 상태에서 힌지축(200)의 회전에 따른 캠(210)의 진퇴운동하는 피스톤(300)의 운동에도 유체의 누설이 없게 된다.Therefore, in the operation space, there is no leakage of the fluid to the movement of the piston 300 moving back and forth with the rotation of the hinge shaft 200 in the state where there is no external leakage of the fluid to be filled for buffering.

즉, 힌지축(200)은 밀폐캡(230)에 의해 힌지공(120)에서 축설치되고 상단부는 외부로 돌출되어 여닫이문과 고정되고, 케이싱(100)은 바닥면에 고정되어 설치된다.That is, the hinge shaft 200 is installed on the hinge hole 120 by the hermetic cap 230 and the upper end thereof is protruded to the outside to be fixed to the hinged door, and the casing 100 is fixed to the bottom surface.

이렇게 구성된 플로어 힌지는 피스톤(300)은 케이싱(100)의 작동공간(110)에 끼워져 힌지축(200)의 캠(210)의 회전에 의해 전진방향에 대응한 유체의 반발유압에 의한 감속 완충된다.The piston 300 is fitted in the working space 110 of the casing 100 and is decelerated and damped by the repulsive oil pressure of the fluid corresponding to the advancing direction by the rotation of the cam 210 of the hinge shaft 200 .

즉, 상기 피스톤(300)은 그 길이방향에 관통된 오리피스의 전방측에 볼과 스프링으로 구성된 체크밸브(C/V)가 설치되어 상기 피스톤(300)의 급격한 전진시에는 체크밸브(C/V)의 작용에 의해 유체의 흐름을 차단하여 완충하여 급격한 닫힘동작이 차단된다.That is, the piston 300 is provided with a check valve (C / V) composed of a ball and a spring on the front side of the orifice penetrating in the longitudinal direction thereof. When the piston 300 is advanced rapidly, The flow of the fluid is shut off and the shock is shut off by buffering.

물론, 이러한 플로어 힌지는 피스톤(300)을 구성하는 몸체 중앙부에 형성된 횡방향의 캠 수용공간(310)에는 양측에 롤러(320)이 축설치되고, 상부개방부(A)을 통해 캠(210)이 수용된 상태로 힌지축(200)이 축설치되며 밀폐캡(230)에 의해 축회전이 고정된 상태로 상단부가 노출된다.Of course, the floor hinge is provided with rollers 320 on both sides in the transverse cam accommodating space 310 formed in the center of the body constituting the piston 300, and the cam 210 is provided through the upper opening A, The hinge shaft 200 is mounted on the shaft and the upper end of the hinge shaft 200 is exposed in a state where the shaft rotation is fixed by the sealing cap 230.

이러한 본 고안은 힌지축(200)의 캠(210)은 반복적으로 정/역회전에 의해 90도 방향에 형성된 걸림홈에 롤러(320)가 걸림되어 개폐상태가 고정된다.In the present invention, the roller 320 is engaged with the engaging groove formed in the direction of 90 degrees by repeatedly rotating the cam 210 of the hinge shaft 200 by the forward / reverse rotation so that the open / closed state is fixed.

물론, 이러한 힌지축(200)의 고정은 일측에서 피스톤(300)을 탄력 지지하는 압축스프링(400)의 탄성력에 의해 캠(210)의 걸림홈에 피스톤(300)의 일측 롤러(320)이 맞결합하여 회전상태가 고정된다.Of course, the hinge shaft 200 is fixed by the elastic force of the compression spring 400 that elastically supports the piston 300 at one side, and the roller 320 at one side of the piston 300 is engaged with the engagement groove of the cam 210 And the rotation state is fixed.

이때, 상기 힌지축(200)에 여닫이문이 축 고정된 상태에서 도 6과 같은 열음동작에는 케이싱(100)의 작동공간(110)에 충전된 유체의 반발유압의 작용이 배제되나, 도 7에 도시된 것과 같은 여닫이문의 닫음동작에는 피스톤(300)의 전진에 대응하여 체크밸브(C/V)가 유체관로인 오리피스를 차단함으로 반발유압이 발생하면서 완충/감속된다.6, the action of the repulsive oil pressure of the fluid filled in the working space 110 of the casing 100 is eliminated. However, as shown in FIG. 7, when the hinge shaft 200 is rotated, In the closing operation of the hinged door as shown, the check valve (C / V) blocks the orifice to the fluid pipe in response to advancement of the piston 300, thereby buffering / decelerating while generating the repulsive oil pressure.

이러한 여닫이문의 개폐동작에 있어 여닫이문의 닫힘동작은 반복적인 하중회전으로 피스톤(300)은 케이싱(100)의 작동공간(110)에서 전진운동과 동시에 충전된 유체의 반발유압, 즉 체크밸브(C/V)의 차단으로 작용함으로 인해서 상기 피스톤(300)의 캠 수용공간(310)의 상부개방부(A)는 내측으로 오그라드는 변형이 발생하려 하나, 도 5에 도시된 것과 같이, 본 발명의 변형방지구(500)에 의해 상부개방부(A)의 내측 수축(오그라듬) 변형이 방지되어 수평의 진퇴동작으로 케이싱(100)의 작동공간(110)과 피스톤(300)의 편마모가 방지되어 상기 피스톤(300)의 원할한 진퇴작동으로 피스톤(300)과 케이싱(100)의 작동공간(110)의 편중마모의 변형이 없이 원활한 작동수명이 보장된다.The closing operation of the hinged door in the opening / closing operation of the hinged door is repeatedly performed by the load rotation, so that the piston 300 moves forward in the operating space 110 of the casing 100, simultaneously with the repulsive oil pressure of the filled fluid, V, the upper opening A of the cam accommodating space 310 of the piston 300 is deformed to the inside. However, as shown in FIG. 5, The inner joint 500 prevents the inner opening of the upper opening A from being deformed so that the operation space 110 and the piston 300 of the casing 100 are prevented from being unevenly worn by the horizontal movement, Smooth operation life of the piston 300 and the casing 100 without any deformation of the working space 110 due to unexpected movement of the piston 300 is ensured.
