がない充分な隙間を明けている。The door frame 1 has a structure in which a frame body 3 formed by bending a metal plate and a space portion of the frame body 3 are filled with a filler 4 such as mortar. A groove 5 is formed along the inner circumference of the frame body 3, and a sealing material 6 made of a highly elastic material such as rubber or plastic is fitted into the groove 5. Further, the inner surface of the upper side of the frame body 6 is inclined toward the opening direction of the door 2 (generally outside the door in the case where the door is provided at the entrance) so that the frontage becomes large, and the free end and the end surface of the door 7 are inclined. And the frame body 3 leave a sufficient gap so that they do not squeeze even when the frame body 3 is deformed.

トライク11の開閉方向の動きを規制している。The strike 11 includes a flat portion 13 having an engaging hole 12 into and from which the lock piece 8 and a latch piece (not shown) that keeps the door 2 closed can be inserted, withdrawn, the latch piece, and the lock piece. V on the door 1 side so that the engagement margin between 8 and strike 11 can be sufficiently secured.
And an engaging projection (14) bent and bent to form a letter. The engaging projection 14 has two surfaces forming an engaging projection so as to engage with the lock piece and the latch piece in the opening direction. The contact surface is a slope. Also, from the engaging projection 14 the cavity
A tongue piece 15 to be inserted into 10 is provided in a row, and a hook portion 16 that engages with the edge of the frame body 3 is formed on the outer edge of the strike 11 so that the tongue piece 15, the hook portion 16 and the frame are formed. The engagement with the body 3 restricts the movement of the strike 11 in the opening / closing direction.
該ストライク11の枠体３への取付けは、前記平坦部13に
穿設した取付孔17を利用し、螺子によってなされる。The strike 11 is attached to the frame body 3 by using a mounting hole 17 formed in the flat portion 13 with a screw.
以下作動を説明する。The operation will be described below.

なくなる様なことはない。Next, when strong deformation external force is applied due to an earthquake or the like and the door frame 1 is deformed as shown in FIG. 9, the end surface of the door 2 and the strike 11
And the engaging projection 14 of. However, since the hook portion 16 continuing from the engaging protrusion 14 is not fixed to the frame body 3,
When a strong force acts on the tip of the engaging projection 14, the hook portion 16 escapes to the left in FIG. 5 and the engaging projection 14 is deformed so as to be flat. Therefore, between the door 2 and the strike 11, even if the door frame 1 is deformed, a large restraining force that prevents the door 2 from opening and closing does not occur. Further, the free end face of the door 2 and the door frame 1 are the door frame 1
Since a sufficient gap is provided so that the doors 2 do not squeeze even when deformed, the door 2 does not squeeze with the door frame 1 and cannot be opened or closed.
更に、前記した様に枠体３の上辺内面は傾斜しているの
で、扉２が扉枠１の上下方向で圧迫されたとしても、扉
２は開方向には動き得る。Further, since the inner surface of the upper side of the frame body 3 is inclined as described above, even if the door 2 is pressed in the vertical direction of the door frame 1, the door 2 can move in the opening direction.

るので、閉時の扉２のガタツキが抑止される。Next, FIGS. 6 to 8 show another shape of the strike. In the strike 11, the V-shaped engaging projection 18 is formed symmetrically so as to face the engaging projection 14. The lock piece 8 and the latch piece (not shown) are provided with the two engaging protrusions 1.
When the door 2 is fitted into and disengaged between the lock pieces 4 and 18, and the lock piece is not locked in particular, the engagement allowance between the latch piece and both the engagement projections 14 and 18 is large. Since the opening / closing is restricted in both directions, rattling of the door 2 when closed is suppressed.
該ストライク11に於いても取付けは、平坦部13を螺子に
より固着するのみであるので、両係合突起14,18は突端
に大きな力が作用すると潰れて平偏化し、扉枠１の変形
があっても扉２の開閉を可能とする。Even in the case of the strike 11, since the flat portion 13 is fixed only by the screw, the engaging projections 14 and 18 are flattened and flattened when a large force acts on the projecting end, and the door frame 1 is not deformed. Allows opening and closing of the door 2 even if there is.
尚、上記ストライク11に於ける係合突起の形状はＶ字状
をＵ字状とする等、種々考えられることは言うまでもな
い。要は係合突起を突端に力が作用した場合に、変形が
可能である様にしておけばよい。Needless to say, the engagement projections in the strike 11 may have various shapes such as a V-shape in a U-shape. In short, it suffices that the engaging projection be deformable when a force is applied to the tip.

第２次災害を誘発することを防止する。[Effect of the Invention] As described above, according to the present invention, even if a strong external force acts on the door frame due to an earthquake or the like and the door frame is deformed, the door can be opened and closed, and a person can be opened in a disaster. It is prevented from being trapped inside the building and inducing the second disaster.
