Abstract The present invention relates to a door fastener, comprising: a plate (10) whose front surface is flat; a pair of fixing units (20) which are respectively combined with a pair of hinge shafts (11), which protrude from the front surface of the plate (10) forward with a certain interval from each other, and which horizontally rotate; and a pressurizing button (30) which is placed between the pair of fixing units (20) and which horizontally rotate the pair of fixing units (20). The pair of fixing units (20) have a sawtooth (21) on the top surface and a hook (40) on the bottom surface. On both side surfaces of the pressurizing button (30) formed is a rack gear (31) which comes in contact with the sawtooth. The pair of fixing units (20) are symmetrically rotated clockwise or counterclockwise by the vertical motion of the rack gear (31). The present invention aims to install the door fastener on the bottom end of a door of a piece of furniture or an entrance door of a building and to fasten the door. When the pressurizing button on the fastener is pressed, the fixing units come in contact with the ground surface to fasten the door. On the other hand, if the bottom pressurizing button is pressed, the fixing units, which are in contact with the ground surface, are detached from the ground surface to allow the door to be moved. Accordingly, the operation is convenient, and the door fastener can be installed without limitation to the type of door. 본 발명은 문고정구에 관한 것으로, 전면이 평평한 플레이트(10)와, 상기 플레이트(10)의 전면에 서로 일정간격을 두고 전면으로 돌출형성된 한 쌍의 힌지축(11)에 각각 결힙되어 좌우방향으로 회동하는 한 쌍의 고정부(20)와, 상기 한 쌍의 고정부(20) 사이에 위치하여 상기 한 쌍의 고정부(20)를 좌우방향으로 회동시키는 가압버튼(30)으로 구성되되, 상기 한 쌍의 고정부(20)의 상면에는 톱니(21)가 형성되고, 하면에는 걸고리(40)가 형성되며, 상기 가압버튼(30)의 양측면에는 상기 톱니에 접촉하는 랙기어(31)가 형성되어 있어 상기 랙기어(31)의 상하이동에 의해 상기 한 쌍의 고정부(20)는 시계방향 또는 반시계방향으로 서로 대칭되어 회동하는 것을 포함하는 것으로, 본 발명은 가구, 건물의 현관문 등의 문 하단에 고정구를 설치하여 문을 고정시키는 것으로, 고정구에 구비된 가압버튼을 누르면 고정부가 지면에 접촉하여 문이 고정되고, 반대로 하부가압버튼을 누르면 지면에 접촉된 고정부가 지면과 떨어지게 되어 문을 움직일 수 있어 조작이 간편하며 문 종류에 제약을 받지 않고 설치하여 사용할 수 있는 현저한 효과가 있다.
AbstractList The present invention relates to a door fastener, comprising: a plate (10) whose front surface is flat; a pair of fixing units (20) which are respectively combined with a pair of hinge shafts (11), which protrude from the front surface of the plate (10) forward with a certain interval from each other, and which horizontally rotate; and a pressurizing button (30) which is placed between the pair of fixing units (20) and which horizontally rotate the pair of fixing units (20). The pair of fixing units (20) have a sawtooth (21) on the top surface and a hook (40) on the bottom surface. On both side surfaces of the pressurizing button (30) formed is a rack gear (31) which comes in contact with the sawtooth. The pair of fixing units (20) are symmetrically rotated clockwise or counterclockwise by the vertical motion of the rack gear (31). The present invention aims to install the door fastener on the bottom end of a door of a piece of furniture or an entrance door of a building and to fasten the door. When the pressurizing button on the fastener is pressed, the fixing units come in contact with the ground surface to fasten the door. On the other hand, if the bottom pressurizing button is pressed, the fixing units, which are in contact with the ground surface, are detached from the ground surface to allow the door to be moved. Accordingly, the operation is convenient, and the door fastener can be installed without limitation to the type of door. 본 발명은 문고정구에 관한 것으로, 전면이 평평한 플레이트(10)와, 상기 플레이트(10)의 전면에 서로 일정간격을 두고 전면으로 돌출형성된 한 쌍의 힌지축(11)에 각각 결힙되어 좌우방향으로 회동하는 한 쌍의 고정부(20)와, 상기 한 쌍의 고정부(20) 사이에 위치하여 상기 한 쌍의 고정부(20)를 좌우방향으로 회동시키는 가압버튼(30)으로 구성되되, 상기 한 쌍의 고정부(20)의 상면에는 톱니(21)가 형성되고, 하면에는 걸고리(40)가 형성되며, 상기 가압버튼(30)의 양측면에는 상기 톱니에 접촉하는 랙기어(31)가 형성되어 있어 상기 랙기어(31)의 상하이동에 의해 상기 한 쌍의 고정부(20)는 시계방향 또는 반시계방향으로 서로 대칭되어 회동하는 것을 포함하는 것으로, 본 발명은 가구, 건물의 현관문 등의 문 하단에 고정구를 설치하여 문을 고정시키는 것으로, 고정구에 구비된 가압버튼을 누르면 고정부가 지면에 접촉하여 문이 고정되고, 반대로 하부가압버튼을 누르면 지면에 접촉된 고정부가 지면과 떨어지게 되어 문을 움직일 수 있어 조작이 간편하며 문 종류에 제약을 받지 않고 설치하여 사용할 수 있는 현저한 효과가 있다.
