Description
【０００１】[0001]
本考案は、扉の構造に関し、特に防火扉、玄関扉、安全扉及び防音扉等に適し 、良好な防火、防煙、防音等の効果を得る扉に関するものである。 The present invention relates to a door structure, and more particularly to a door which is suitable for fire doors, entrance doors, safety doors, soundproof doors, etc., and has good fireproof, smokeproof, and soundproof effects.
【０００２】[0002]
従来の扉の扉板の両側辺と扉枠との嵌合は、扉板の側辺、扉枠共すべて直角に なっていて、互いに平行面で配設されている。また、通常の防火扉、玄関扉、安 全扉及び防音扉等の鍵の鍵栓は、扉枠の一個所の締付けだけになっている。 In the conventional doors, both sides of the door plate and the door frame are fitted at right angles to both sides of the door plate and the door frame, and are arranged in parallel with each other. In addition, locks for keys such as ordinary fire doors, entrance doors, safety doors, soundproof doors, etc. are only tightened at one location on the door frame.
【０００３】[0003]
前記従来の扉では、扉板と扉枠との間は平行になっていて、その上多少の隙間 がある。従ってバールなどをその隙間に差し込んで強引に拡開した場合、扉は容 易に壊されてしまう。また、扉が外力の衝撃を受けた場合、扉板と扉枠は彎曲変 形し、更に扉の蝶番が腐蝕して脱落した場合、破壊されて扉枠から扉が離脱した 場合等は、扉は倒れ易くなり非常に危険な状態になる。 更に、一般の金属製扉は火災時には、熱を受けて扉と扉枠は膨張して変形し、 扉と扉枠とは一般に平行面であるため、扉は噛み付いて開かなくなってしまう。 また、従来の扉は開閉を容易にするために、扉と扉枠との接触個所には隙間を 残しているため、煙が発生すると煙は隙間から入り込み、また流出し防煙効果は 充分なものではない。 扉が閉められいる場合、鍵によって扉と扉枠を締付け固定して容易に開かない ようにし、また鍵は壊されにくい構成になっている必要がある。しかし、従来の 扉では、鍵は扉枠の凡そ同じ一個所に取付けられているだけであるので、鍵の位 置を予測して工具等でこじることで破壊することができてしまう。 In the above-mentioned conventional door, the space between the door plate and the door frame is parallel to each other, and there is some gap above the door. Therefore, if a crowbar or the like is inserted into the gap and forcibly expanded, the door is easily broken. If the door is subjected to an external force, the door plate and the door frame are bent and deformed, and if the hinge of the door is corroded and falls off, or if the door is broken and the door is detached from the door frame, etc. Can easily fall over and become very dangerous. Furthermore, in the event of a fire, a general metal door receives heat and the door and the door frame expand and deform. Since the door and the door frame are generally parallel planes, the door bites and cannot be opened. In addition, conventional doors have a gap at the contact point between the door and the door frame to facilitate opening and closing, so if smoke is generated, the smoke enters through the gap and flows out, and the smoke prevention effect is sufficient. Not something. When the door is closed, it is necessary to secure the door and the door frame with the key so that it cannot be easily opened, and the key must be hard to break. However, in the conventional door, the key is mounted only at approximately the same location on the door frame, so that the key can be destroyed by predicting the key position and prying with a tool or the like.

【００１３】 上述の構成による扉板１及び扉枠２の動作を説明する。 図１及び図１４に示すように、扉が開き状態にある場合は、制動装置５の押し 棒５４は扉枠２を押えないので、図１５（ａ）のように押し棒５４に設けられて いるコイルバネ５４２の張力によって押し棒５４は扉板１の外側に引き出され、 それに伴って制動板５３の前端にある嵌制塊５３１が滑動板５２の凹溝５２１に 契合する。そのため鍵栓装置４の上栓軸４３のコイルバネ４３２は上栓軸４３を 引き上げることができなくなり、よって滑動板５２の先端の栓軸５２２及び横栓 軸４２、下栓軸４４は扉板１の内部に保持され扉は開いた状態にある。The operation of the door plate 1 and the door frame 2 having the above configuration will be described. As shown in FIGS. 1 and 14, when the door is in the open state, the push rod 54 of the braking device 5 cannot press the door frame 2, so that the push rod 54 is provided on the push rod 54 as shown in FIG. The push rod 54 is pulled out of the door plate 1 by the tension of the coil spring 542, and the fitted mass 531 at the front end of the braking plate 53 engages with the concave groove 521 of the sliding plate 52. As a result, the coil spring 432 of the upper plug shaft 43 of the lock device 4 cannot lift the upper plug shaft 43, so that the plug shaft 522, the horizontal plug shaft 42, and the lower plug shaft 44 at the tip of the sliding plate 52 The door is held open inside.
【００１４】 続いて扉を閉めた場合、扉板１の回動固定側側辺と扉枠２とが密着して、図１ ５（ｂ）のように押し棒５４は扉板１内部に押し戻され、制動板５３の嵌制塊５ ３１が滑動板５２の凹溝５２１から離れることになる。これによって上栓軸４３ のコイルバネ４３２はその張力で上栓軸４３を引き上げ、滑動板５２を上向きに 摺動して栓軸５２２を扉板１の上部孔１７から突出させ扉枠２の栓孔２５内に挿 入する。Subsequently, when the door is closed, the rotation fixed side of the door plate 1 and the door frame 2 come into close contact with each other, and the push rod 54 is pushed back into the door plate 1 as shown in FIG. As a result, the fitted block 331 of the braking plate 53 is separated from the groove 521 of the sliding plate 52. As a result, the coil spring 432 of the upper plug shaft 43 pulls up the upper plug shaft 43 by the tension, slides the sliding plate 52 upward to cause the plug shaft 522 to protrude from the upper hole 17 of the door plate 1, and the plug hole of the door frame 2 is opened. Insert into 25.

Then, the lower stopper shaft 44 is made to protrude from the lower hole 16 and inserted into the stopper hole 25 of the door frame 2 so that the door plate 1 and the door frame 2 are automatically attached at many places, in this case, three places. Will be locked. When a person pushes down on the handle 14 to open the door, the handle 14 rotates the disk 41 until the rotation limiting pin 142 hits the full position limiting hole 411 in the direction of the arrow as shown in FIG. The horizontal stopper shaft 42, the lower stopper shaft 43, and the stopper shaft 522 of the braking device 5 are retracted into the door plate 1, and the door plate 1 is unlocked from the door frame 2 to open the door, and at the same time, the push rod of the braking device 5 The member 54 is separated from the door frame 2 and is pushed out of the door plate 1 again by the tension of the coil spring 542 as shown in FIG. The fitted mass 531 of the brake plate 53 is engaged again in the groove 521, and the plug shafts 42, 44, 522 are held in the door plate 1.
