Description

방화벽용 스크린 롤업셔터의 방화벽원단 끼임 방지장치{Screen roll-up shutter for preventing firewall fabric from chain trapping}{Screen roll-up shutter for preventing firewall fabric from chain trapping}

본 발명은 방화벽용 스크린 롤업셔터 원단끼임 방지장치에 관한 것이다.The present invention relates to a screen roll-up shutter fabric jamming prevention device for a firewall.

롤업셔터는 방화벽용 원단이나 셔터를 감아 올리거나 풀어서 공간을 막는 용도로 사용된다.Roll-up shutters are used to block a space by rolling up or unwinding firewall fabric or shutters.

이러한 기능을 하는 종래의 장치로, 도 1은 종래의 롤업셔터의 분해사시도 이고, 도 2는 종래의 롤업셔터에 사용되는 동력전당 연결구의 사시도이다.As a conventional device that performs this function, Figure 1 is an exploded perspective view of a conventional roll-up shutter, and Figure 2 is a perspective view of a power hall connector used in a conventional roll-up shutter.

도1에서 보는 바와 같이 종래의 롤업셔터(100)는 건축물의 내부 일측에 설치되는 고정판(110)과, 고정판(110)에 회전가능하게 결합되는 내경공간(121)을 가지는 고나체형 회전관(120)과, 일단부가 회전관(120)의 외면에 결합되고 승하강 하는 방화천(130)와, 회전관(120)의 단부에 결합되는 연결구(140) 및 고정판(110) 내에 설치되고 연결구(140)에 회전력을 인가하는 모터(150)로 구성된다.As shown in Figure 1, the conventional roll-up shutter 100 has a fixed plate 110 installed on one side of the interior of the building, and a high-naked rotary tube 120 having an inner diameter space 121 rotatably coupled to the fixed plate 110. ), one end of which is coupled to the outer surface of the rotary tube 120 and a fire protection cloth 130 that goes up and down, a connector 140 coupled to the end of the rotary tube 120, and a fixed plate 110 installed in the connector 140. ) consists of a motor 150 that applies rotational force to the motor.

여기서 회전관(120)은 일단부 내면으로부터 내측방향으로 돌출된 돌출키(122)가 형성되고, 연결구(140)는 도2에서 보는 바와 같이 외면 일측에 회전관(120)의 돌출키(122)가 삽입되는 키홈(141)이 형성된다.Here, the rotary tube 120 is formed with a protruding key 122 that protrudes inward from the inner surface of one end, and the connector 140 has a protruding key 122 of the rotary tube 120 on one side of the outer surface as shown in Figure 2. A key groove 141 into which is inserted is formed.

이러한 종래의 롤업셔터(100)는 모터(150)로부터 연결구(140)로 회전력이 인가되면 연결구(140)가 회전하고, 연결구(140)의 키홈(141)에 삽입된 회전관(120)의 돌출키(122)가 연결구(140)의 일측에 지지되면서 연결구(140)가 회전함에 따라 동반회전하게 된다. 실제 사용시 돌출키(122)는 링판(123)의 내경 방향으로 돌출되고, 링판(123)은 회전관(120)의 내경공간(121)테두리 부분을 막도록 용접되며, 도 3 에서는 설명의 편리상 돌출키(122)를 가지는 링판(123) 만 위치시킨 상태로 도시한 사진임을 날 수 있을 것이다.In this conventional roll-up shutter 100, when a rotational force is applied from the motor 150 to the connector 140, the connector 140 rotates, and the rotary tube 120 inserted into the key groove 141 of the connector 140 protrudes. The key 122 is supported on one side of the connector 140 and rotates together with the rotation of the connector 140. In actual use, the protruding key 122 protrudes in the inner diameter direction of the ring plate 123, and the ring plate 123 is welded to block the border portion of the inner diameter space 121 of the rotary tube 120. In Figure 3, for convenience of explanation, You can see that the photo is shown with only the ring plate 123 having the protruding key 122 positioned.

사용시 회전관(120)에 결합된 방화천(130)이 회전관(120)에 권취되거나 풀리면서 승하강하여 건물 내의 통로를 개폐하여 방화벽 기능을 하게 된다.When in use, the firestop cloth 130 coupled to the rotary tube 120 is wound or unwound around the rotary tube 120 and goes up and down to open and close passages in the building to function as a firewall.

그러나, 종래의 롤업셔터(100)는 연결구(140)가 하나의 뭉치로 형성되어 회전관(120)의 돌출키(122)가 지지되도록 조인트(140)와 접촉하여야 하고, 이러한 근접접촉은 방화벽 기능을 하기 위하여 감기는 방화천(130)의 신축성 및 유연성에 의하여 간혹 회전관(120)의 단부를 지나도록 경사지게 감기게 되고, 이러한 경사감김은 방화천이 모터(150)의 동력을 전달하는 체인이 체인기어에서 벗어나게 작용하여, 방화천이 감김상태에서 동력을 받지 못하여 회전관(120)에서 자유낙하하도록 한다. However, in the conventional roll-up shutter 100, the connector 140 is formed as a single bundle and must be in contact with the joint 140 so that the protruding key 122 of the rotary tube 120 is supported, and this close contact functions as a firewall. In order to do this, due to the elasticity and flexibility of the fire protection cloth 130, it is sometimes wound obliquely so as to pass the end of the rotary tube 120, and in this oblique winding, the chain that transmits the power of the fire protection cloth motor 150 is a chain. It acts to deviate from the gear, causing the fireproof cloth to fall freely from the rotating tube 120 because it does not receive power in the wound state.

이러한 자유낙하는 방화천이 10키로 에서 30 키로 정도 되고, 방화천(130) 하단에 수평을 잡기 위하여 결합한 티바의 중량도 10내지 30키로 되므로, 이러한 방화천의 급속하강은 그 밑을 지나는 인명 피해와 자동차 등의 재산 피해가 속출하는 문제점을 가진다.In this free fall, the weight of the fire prevention cloth is about 10 to 30 kg, and the weight of the T-bar combined to level the bottom of the fire protection cloth 130 is also 10 to 30 kg, so the rapid descent of the fire protection cloth causes damage to people passing under it and The problem is that damage to property such as cars continues to occur.

본 발명은 이를 해결하고자하는 것으로 본 발명의 목적은 모터의 동력을 롤업셔터의 회전관에 전달하는 연결구의 돌출링 높이를 높이고, 높인만큼 체인기어와 체인을 합한 직경보다 큰 직경의 차단판을 부가하여, 방화벽용 방화천의 감김쏠림으로 체인을 체인기어에서 이탈시키는 것을 막아주어, 방화천 원단이 체인기어와 체인 사이에 끼임을 방지하여 롤업셔터의 안정성을 확보토록 하는 방화벽용 스크린 롤업셔터 원단끼임 방지장치를 제공하려는 것이다.The present invention seeks to solve this problem. The purpose of the present invention is to increase the height of the protruding ring of the connector that transmits the power of the motor to the rotating tube of the roll-up shutter, and to add a blocking plate with a diameter larger than the combined diameter of the chain gear and chain as the height increases. This prevents the chain from being separated from the chain gear due to the winding of the firestop cloth for the firewall, preventing the firestop fabric from getting caught between the chain gear and the chain, thus securing the stability of the roll-up shutter. The goal is to provide a prevention device.

본 발명의 목적은 모터의 동력을 롤업셔터의 회전관에 전달하는 연결구의 돌출링 높이를 높이고, 졸출링을 지지하는 지지판의 두께도 체인의 수직면에 닿지 않도록 두껍게하여, 방화벽용 방화천의 감김쏠림으로 체인을 체인기어에서 이탈시키는 것을 막아주어, 방화천 원단이 체인기어에 초기 접근을 막아주어 롤업셔터의 안정성과 내구성을 확보토록 하는 방화벽용 스크린 롤업셔터 원단끼임 방지장치를 제공하려는 것이다. The purpose of the present invention is to increase the height of the protruding ring of the connector that transmits the power of the motor to the rotary tube of the roll-up shutter, and to increase the thickness of the support plate supporting the protruding ring so that it does not contact the vertical surface of the chain, thereby preventing the winding of the fireproof cloth for the firewall from leaning. The purpose is to provide a screen roll-up shutter material jamming prevention device for firewalls that prevents the chain from being separated from the chain gear and prevents the fireproof fabric from initial access to the chain gear, ensuring the stability and durability of the roll-up shutter.
