본 고안은 문설주골조와 문지방골조 그리고 문짝골조를 플로아힌지와 간단한 구조로 조립시켜 현관문을 자동으로 개폐할 수 있는 자동개폐를 할수 있는 현관문과 그 문틀의 골조에 관한 것이다.The present invention relates to a door frame and door frame that can be opened and closed automatically by opening and closing the door frame, door frame frame and door frame with a floor hinge and a simple structure.

지금까지는 현관문을 자동을 개폐하기 위하여 현관문틀에 현관문을 경첩으로 연결하고 문과 문틀상부에 도어체크를 부착시켜 사용하거나 또는 플로아힌지를 현관의 콘크리트바닥을 파고 매몰되게 설치하였으나 본 고안에서는 문설주골조와 문지방골조 그리고 문짝골조에 플로아힌지를 동시에 견고하고 간단한 작업으로 조립할 수 있도록 문지방골조를 플로아힌지가 상하두께와 좌우폭으로 꽉 끼우게 삽입될 수 있는 내부공간부에 전, 후부판의 내부중간에 돌출된 나사못체결구가 플로아힌지의 전후돌출부를 고정되게 받쳐주고 상판 일측중간부를 요입부로 절개시켜 플로아힌지가 삽입시 개폐돌기가 상부로 돌출되게 형성시킨 문지방골조 일측에 내측판을 후부측 절반이 종함입단으로 형성되고 내측판의 하단부를 문지방골조의 상부외곽체에 맞게 요입부로 절개시킨 문설주골조를 나사못으로 직각이 되게 부착시켜 문틀로 조립시키고 문설주골조 내측판의 종함입단에는 외측판에 전부측선단의 굴곡편과 후부판선단의 함입단이 형성되고 후부판과 연결되어 문지방골조의 상부돌출단 폭으로 돌출된 내측판이 전부쪽으로 외측판 중간부까지 만곡판으로 형성시킨 보조골조를 나사못으로서 체결시켜 문설주에 개폐되는 문짝의 사이간격을 막아주고 플로아힌지의 개폐돌기상부에는 반원형외측판에 내측의 전,후로 문장식판이 협지될 협지간격이 형성된 문짝일측골조를 중앙부에 개폐돌기의 삽입통공이 형성되고 외형체는 문짝일측골조의 반원형외측판과 일치되어 삽입될 수 있는 캡으로 문짝을 자동으로 개폐되게 조립시킬 수 있는 것으로 도면에 의거 상세히 설명하면 다음과 같다.Until now, in order to automatically open and close the front door, the front door is connected to the door frame with a hinge and a door check is attached to the door and the upper part of the door frame, or the floor hinge is dug into the concrete floor of the front door and buried. In order to assemble the floor hinge into the frame, door frame, and door frame at the same time, the door hinge is inserted into the inner space where the floor hinge can be inserted tightly in the top, bottom, left and right widths. A screw fastener protruding from the middle supports the front and rear projections of the floor hinge fixedly, and cuts the middle part of the upper plate into the indentation so that the opening and closing projection protrudes upward when the floor hinge is inserted. The side half is formed by the indentation and the lower end of the inner plate is fitted to the upper outline of the door frame. The dorsal frame, which is cut into the indentation, is attached at right angles with a screw to assemble into a door frame.The bent end of the posterior side is formed at the end of the inner plate of the inner plate of the dorsal frame and the recessed end of the posterior plate is connected to the rear plate. The inner frame protruding from the width of the upper protruding end of the door frame is fastened to the middle of the outer plate by a curved plate to prevent the gap between the doors opening and closing on the doorposts. The opening of the opening and closing projections is formed in the center of the door frame with a gap between the inner and outer sides of the semicircular outer plate, and the cap can be inserted in line with the semicircular outer plate of the one side frame. The door can be assembled to be automatically opened and closed as described in detail based on the drawings as follows.

플로아힌지(1)가 상하두께와 좌우폭으로 꽉 끼우게 삽입될 수 있는 내부공간부에 전, 후부판(11),(12)의 내부중간에 돌출된 나사못체결구(16)가 플로아힌지(1)의 전후돌출부를 고정되게 받쳐주고 상판(13) 일측중간부를 요입부(14)로 절개시켜 플로아힌지가 삽입시 개폐돌기(2)가 상부로 돌출되게 형성시킨 문지방골조(10)에 플로아힌지가 삽입된 쪽의 일측에 내측판(11)을 후부측 절반이 종함입단(22)으로 형성되고 내측판(21)의 하단부를 문지방골조의 상부외곽체에 맞게 요입부(23)로 절개시킨 문설주골조(20)를 나사못으로 부착시키고 문설주골조(20) 내측판의 종함입단(22)에는 외측판(32)에 전부측선단의 굴곡편(33)과 후부판(34) 선단의 함입단(35)이 형성되어 탄력으로 꽉 끼우도록 조립시킬 수 있고 후부판(34)과 연결되어 문지방골조(10)의 상부돌출단(15) 폭으로 돌출된 내측판(31)이 전부쪽으로 외측판 중간부까지 만곡판(36)으로 형성시킨 보조골조(30)를 나사못으로서 문설주골조와 나사못홈(37)을 통해 체결시키고 플로아힌지의 개폐돌기(2) 상부에는 반원형외측판(4)에 내측의 전,후로 문장식판이 협지될 협지간격(42)이 형성된 문짝일측골조(40)를 중앙부에 개폐돌기의 삽입통공(51)이 형성되고 외형체는 문짝일측골조의 반원형 외측판과 일치되어 삽입될 수 있는 캡(50)으로 문짝을 자동으로 개폐되게 조립시켜 된 것으로 미설명부호(3)는 사이간격틈을 막아주는 패킹의 삽입홈이다.The screw fastener 16 protruding between the inside and the rear plate 11 and 12 in the inner space where the floor hinge 1 can be inserted into the upper and lower thickness and the left and right width tightly is the floor hinge. (1) to the front and rear projections fixed to the upper plate 13, one side middle portion is cut into the indentation portion (14) to the door hinge frame (10) formed so that the opening and closing projections (2) protrude upward when the floor hinge is inserted The inner side plate 11 is formed on one side of the side where the floor hinge is inserted, and the rear half of the rear side is formed by the end of the bell box 22, and the lower end portion of the inner plate 21 is fitted into the indentation part 23 in accordance with the upper outer body of the door frame. Attaching the dissected door brace frame 20 with a screw, and the end of the door 22 of the inner plate of the door brace frame 20 includes the bent pieces 33 and the rear plate 34 of the front end on the outer plate 32. The mouth 35 is formed so that it can be assembled to fit tightly and connected to the rear plate 34 to the width of the upper protrusion 15 of the door frame 10. The auxiliary frame 30 formed by the curved plate 36 protruding from the inner side plate 31 to the middle of the outer side plate is fastened through the door post frame and the screw groove 37 with screws, and the opening and closing protrusion of the floor hinge ( 2) In the upper part of the semi-circular outer plate (4) is formed in the opening side of the opening frame (51) of the opening and closing protrusions (40) formed in the center of the gap between the gripping plate 42, which is to be sandwiched between the inner and the outer plate 4 is formed It is to be assembled to open and close the door automatically with a cap 50 that can be inserted in accordance with the semi-circular outer plate of the door frame one side (3) is the insertion groove of the packing to prevent the gap between.

이와 같은 구조로 된 본 고안은 문지방골조(10)의 구조를 플로아힌지(1)가 내부로 삽입되어 고정되도록 상하두께와 좌우폭에 맞는 내부공간부에 전,후부판(11),(12)의 내부중간에 돌출된 나사못체결구(16)가 플로아힌지의 전후돌출부를 고정되게 형성시키고 상판(13) 일측중간부를 요입부(14)로 절개시켜 플로아힌지가 삽입시 개폐돌기(2)가 상부로 돌출되게 형성시킨 문지방골조(10)에 플로아힌지가 삽입된 일측으로 내측판(21)의 하단부를 문지방골조의 상부외곽체에 맞게 요입부(23)로 절개시킨 문설주골조(20)를 나사못으로 부착시켜 문틀로 조립시키고 이 문설주골조(20) 내측판(21)에 형성된 종함입단(22)에는 외측판(32)에 전부측선단의 굴곡편(33)과 후부판(34) 선단의 함입단(35)이 형성시켜 탄력으로 꽉 끼워 조립시킬 수 있고 후부판(34)과 연결되어 문지방골조(10)의 상부돌출단(15) 폭으로 돌출된 내측판(31)이 전부쪽으로 외측판의 중간부까지 만곡판(36)으로 형성시킨 보조골조(30)를 나사못으로서 문설주골조와 체결시켰으므로 문짝이 문틀내부에서 회전되게 개폐될 수 있는 위치에 있더라도 문틀과 문짝의 사이간격을 이 보조골조가 후부측에서 막아주고 플로아힌지의 개폐돌기(2) 상부에는 반원형외측판(41)에 내측의 전,후로 문장식판이 협지될 협지간격(42)이 형성된 문짝일측골조(40)로서 플로아힌지의 개폐돌기(2)를 중앙부의 삽입통공(51)으로 삽입시킨 캡(50)을 반원형 외형체가 일치되는 일측골재의 반원형외측면으로 삽입시켜 문짝을 문틀에서 자동으로 개폐되게 조립시킬 수가 있는 것이다.The present invention having such a structure is the front and rear plates (11), (12) in the inner space to fit the vertical thickness and the left and right width so that the floor hinge (1) is inserted into the fixed structure of the door frame (10) Screw fasteners 16 protruding in the inner middle of the formed to form the front and rear projections of the floor hinge fixed and cut the middle portion of one side of the upper plate 13 with the recessed portion 14 when opening and closing the floor hinge (2) Frame 20 in which the lower end of the inner plate 21 is cut into the indentation portion 23 to fit the upper outer body of the silo frame at the side where the floor hinge is inserted into the silo frame 10 formed to protrude upwards To be assembled with a door frame and assembled into a door frame, and the longitudinal end 22 formed in the inner plate 21 of the dowel frame 20 has a front end 32 with a bent piece 33 and a rear plate 34 at the front end. The indentation end of the 35 is formed and can be assembled tightly and elastically and is connected with the back plate 34 and the threshold Since the inner side plate 31 protruding from the upper protrusion end 15 width of the upper portion 10 is joined to the scaffolding frame with the auxiliary frame 30 formed by the curved plate 36 all the way to the middle of the outer side plate with screws. Even though the door is in a position where the door can be rotated and opened inside the door frame, the auxiliary frame prevents the gap between the door frame and the door from the rear side and the semi-circular outer plate 41 on the opening / closing protrusion 2 of the floor hinge. The semicircular outer body has a cap 50 into which the opening and closing projections 2 of the floor hinge are inserted into the insertion hole 51 in the center, as the one side frame 40 in which the interstitial plate 42 is formed to sandwich the plate. By inserting the semicircular outer surface of the matching one side aggregate, the door can be assembled to open and close automatically in the door frame.

이상과 같이 본 고안은 문틀에 문짝을 자동으로 개폐되게 조립시킴에 있어서 경첩과 도어체크가 필요없이 또한 플로아힌지도 종래처럼 현관의 콘크리트바닥을 파고 매몰되게 설치시킬 필요가 없이 문틀과 문짝만으로 간단하게 조립시킬 수가 있는 것이다.As described above, the present invention is easy to assemble the door to open and close automatically, so that the hinge and the door check are not necessary and the floor hinge does not need to be dug and buried like the conventional concrete floor. Can be assembled.
