SYSTEM FOR PREVENTING DOOR FROM CLOSING AJAR (HALF DOOR OPENING) AND COMPLETING CLOSURE CALMLY
To provide a system for preventing a door from closing ajar (half door opening) upon completion of door closure and for reducing shock noise upon completion of sharp door closure.SOLUTION: A system prevents a door from closing ajar (half door opening) upon slowly closing the door by controlling supply current to both of magnets M1, M2 attached on a casing of the door and the door to face to each other right before the door close completely to make those magnetic poles different to each other with force attracting the door to complete closure. Further, it prevents the door from closing sharply at a moment with repulsive force of the magnetic poles facing to each other which are controlled to be the same magnetic poles right before the door complete closure when the door is sharply closed, and then are sequentially controlled to become different magnetic poles to generate attraction force to close the door completely. In any occasion when closing the door completely, the system mitigates shock sound through abutment of an air spring arranged with an air discharging hole and the door with a coil spring in order to reduce supply power to the magnets M1, M2 attached on the casing of the door and the door to face to each other.SELECTED DRAWING: Figure 20
【課題】扉の閉鎖完了時の半締り（半ドア）を防止し、また急激な扉閉鎖完了時のショック音を軽減するシステムを提案する。【解決手段】扉がゆっくりと閉じられた時、扉閉鎖完了直前に扉枠側と扉に向き合うように取り付けた両電磁石Ｍ１，Ｍ２への供給電流を操作して、向き合う互いの電磁極を異磁極化し、その吸引力で扉を引き寄せ閉鎖を完了して半締り（半ドア）を防止する。また扉が急激に閉鎖された場合には、扉閉鎖完了直前に向き合う互いの電磁極を同磁極化してその反発力で一旦急激な扉の閉鎖を抑制し、引き続いて互いの電磁極を異磁極化して、その吸引力で扉を引き寄せ閉鎖を完了する。いずれの場合も扉の閉鎖完了時には扉枠側と扉に向き合うように取り付けた電磁石Ｍ１，Ｍ２への供給電力を少なくするために、空気吸排出孔を設けた空気バネと、コイルバネ付の戸当りによりショック音を緩和して扉の閉鎖を静穏に完了することができる。【選択図】図２０
