【考案の詳細な説明】
この考案は面付錠に取付けられた扉が、地震などの振動
によって扉枠の方に移動されたときにも、扉の開放を支
障なく行うことができる耐震用扉枠に関する。[Detailed explanation of the invention] This invention is an earthquake-resistant door that can open the door without any trouble even when the door attached to the surface lock is moved toward the door frame due to vibrations such as an earthquake. Regarding the frame.
一般に、面付錠を取付けられた扉と扉枠との関係は、第
１図に示すように、面付錠と扉枠の端面との隙間ａ。Generally, the relationship between a door to which a surface lock is attached and the door frame is as shown in FIG. 1, where there is a gap a between the surface lock and the end surface of the door frame.
が、開放端側の扉の縦方向端面とこれに対向する扉枠の
端面との隙間Ｃよりわずかに大きくなるように取付けら
れており、小さい方の隙間Ｃは３〜４ｍｍと小さいため
、地震などの振動によって扉と扉枠とが相対的に少い移
動しても両者は容易に接触し、扉の開放を支障なく行う
ことができなくなる欠点があった。However, it is installed so that it is slightly larger than the gap C between the vertical end face of the open end door and the opposite end face of the door frame, and the smaller gap C is 3 to 4 mm, so it is difficult to prevent earthquakes. Even if the door and door frame move by a relatively small amount due to vibrations such as these, they easily come into contact with each other, making it impossible to open the door without any trouble.
この考案は、面付錠を取付けられた扉において、上記欠
点を解消することができる耐震用扉枠を提供することを
目的とする。The object of this invention is to provide an earthquake-resistant door frame that can eliminate the above-mentioned drawbacks in a door to which a surface lock is attached.
第２図以下に示す実施例について説明すれば、１は内側

位置する縦方向の扉枠（縦枠）である。To explain the embodiment shown in Fig. 2 and below, 1 is a door with a surface lock 2 attached on the inside, and 3 is a vertical door frame (vertical frame) located on the open end side of the door 1. .
扉１の開放端側縦方向の端面１ａとこれに対向する扉枠
３の縦方向の端面３ａとの隙間ｌは、面付錠２と扉枠３
の別の上下方向の端面３ｂとの間の隙間ａより大きくな
るように形成する。The gap l between the vertical end surface 1a of the open end side of the door 1 and the vertical end surface 3a of the door frame 3 opposing this is the gap between the surface lock 2 and the door frame 3.
It is formed so that it is larger than the gap a between it and another end surface 3b in the vertical direction.
この場合、面付錠２と扉枠３の端面３ｂとの隙間ａは、
面付錠２から突出するラッチ４の長さｌ′の関係から従
来の場合の隙間ａ。In this case, the gap a between the surface lock 2 and the end surface 3b of the door frame 3 is
The gap a in the conventional case is determined by the length l' of the latch 4 protruding from the surface lock 2.
より殆んど拡げることはできないから、扉１の端面１ａ
と扉枠３の端面３ａとの隙間の増加分（ｌ−Ｃ）は、扉
枠３の折曲げ部３Ｃによって作り出される。Since it cannot be expanded much further, the end surface 1a of the door 1
The increase in the gap (l-C) between the door frame 3 and the end surface 3a of the door frame 3 is created by the bent portion 3C of the door frame 3.

る。A movable cover plate 10, which is provided with an opening 10a for the latches 4, 4, has its bent flange portions 10b, 10b in the opening 1 minute between the bent pieces 7a, 7a of the fixed ferrules 7, 7. It is inserted so as to be in contact with the bent pieces 7a, 7a, and the flanges 11a, 11a of the member 11 are in contact with the inner surface of the movable cover plate 10, in which the latch housing portion 12 is formed. .
１３．１３は受は部材１１の底板部分１１ ｂに設けら

5, etc., to the thin plate 16, and the inclined portion 14
b, 14 flange portion 14 formed at one end of b
C and 14C are in contact with a holding member 17 fixed to the door frame 3 so as to be slidable in the vertical direction.
この考案は上記のように構成されているので、地震など
の振動によって扉１が扉枠３の方に移動しても、扉１の
端面１ａと扉枠３の端面３ａとの間の隙間ｌが、面付錠
２の扉枠３の端面３ｂとの隙間ａより大きくなるように
形成しであるので、従来のように扉１の端面１ａが扉枠
３の端面３ａに直接接触しＣ損傷されるのを防止するこ
とができる。Since this device is configured as described above, even if the door 1 moves toward the door frame 3 due to vibrations such as an earthquake, the gap l between the end surface 1a of the door 1 and the end surface 3a of the door frame 3 However, since the surface lock 2 is formed to be larger than the gap a between the end surface 3b of the door frame 3, the end surface 1a of the door 1 comes into direct contact with the end surface 3a of the door frame 3, resulting in damage. It is possible to prevent this from happening.
扉１と扉枠３との最初の接触は、扉１が扉枠３の方向に
ほぼ隙間ａに相当する距離だけ移動したときに、面付錠
２が第４図に示す可動蓋板１０に接触する形で起り、引
続き扉１が扉枠３の方向へ移動するときには、面付錠２

方向に移動させるが、この移動は台形状に形成された折
曲げ板１４のフランジ部１４ Ｃ，１４Ｃが、それぞれ
扉枠３に固設された保持部材１７に対する上下方向への
摺動により吸収させることができる。The first contact between the door 1 and the door frame 3 occurs when the door 1 moves in the direction of the door frame 3 by a distance approximately corresponding to the gap a, when the surface-mounted lock 2 contacts the movable cover plate 10 shown in FIG. When the door 1 continues to move in the direction of the door frame 3, the surface lock 2
The movable cover plate 10 is moved together with the support member 11 in the direction of the holding member 17, but this movement is caused by the fact that the flange portions 14C, 14C of the trapezoidal bent plate 14 are fixed to the door frame 3, respectively. It can be absorbed by sliding the holding member 17 in the vertical direction.
したがって、折曲げ板１４による扉１の変位吸収長さが
、前記隙間ｌと隙間ａとの隙間差（１−ａ）にほぼ等し
くなるように設定しておけば、面付錠２と扉枠３との隙
間ａが、ラッチ４の長さｌ′や面付錠２の取付中心まで
の距離ｌ。Therefore, if the length of the displacement absorption of the door 1 by the bending plate 14 is set to be approximately equal to the gap difference (1-a) between the gap l and the gap a, the surface-mounted lock 2 and the door frame 3 is the length l' of the latch 4 and the distance l to the installation center of the surface-mounted lock 2.
などの関係から余り大きくすることができない場合にも
、扉１と扉枠３との間に十分な耐震性能を付与すること
ができるため、地震などの振動によって扉１が扉枠３の
方向に移動した場合にも、扉１を支障なく開放すること
ができる。Even if the size cannot be increased too much due to the above reasons, it is possible to provide sufficient seismic resistance between the door 1 and the door frame 3, so that the door 1 may move toward the door frame 3 due to vibrations such as an earthquake. Even when moved, the door 1 can be opened without any problem.
なお、面付錠２が第４図に示すような円形の場合には、
可動蓋板１０の長さは、面付錠２の弦の長さｍより太く
なるように定めるだけでよいが、長方形の面付錠２を使
用する場合には、可動蓋板１０の大きさは、面付錠２の
高さ方向の寸法（第４図におけるｈの寸法に相当する）
と見込み方向の寸法（第２図におけるｔの寸法に相当す

を折曲げ板１４の弾性作用に抗して仕切り部材５内に移
動させることはできなくなる。In addition, when the surface lock 2 is circular as shown in Fig. 4,
The length of the movable cover plate 10 only needs to be determined so that it is thicker than the chord length m of the surface-mounted lock 2, but when using a rectangular surface-mounted lock 2, the size of the movable cover plate 10 is the dimension in the height direction of the surface-mounted lock 2 (corresponds to the dimension h in Fig. 4)
The movable cover plate 10 must be set to be larger than the dimension in the projected direction (corresponding to the dimension t in FIG. 2).
cannot be moved into the partition member 5 against the elastic action of the bending plate 14.
第５図はこの考案の他の実施例を示すもので、′可動蓋
板１０にパツキン挿着溝１８を形成した場合を示す。FIG. 5 shows another embodiment of this invention, in which a gasket insertion groove 18 is formed in the movable cover plate 10.
このように可動蓋板１０にパツキン挿着溝１８を形成し
た場合には、該パツキン挿着溝１８内にパツキン１９を
取付けることにより、前記効果に加えて扉１の内面と可
動蓋板１０との間のエアタイトをも良くすることができ
る。When the gasket insertion groove 18 is formed in the movable lid plate 10 in this way, by installing the gasket 19 in the gasket insertion groove 18, in addition to the above-mentioned effect, the inner surface of the door 1 and the movable lid plate 10 can be connected. It is also possible to improve the air tightness between the two.
この考案は以上説明したように、面付錠を取付けられた
扉の面付錠と対向する扉枠の部分に、扉枠と分離した可
動蓋板を設けて、この可動蓋板を受は部材を介して台形
状に形成された折曲げ板によって保持すること・により
、きわめて簡単な構造で且つ安価に、扉枠に対して耐震
性を付与することができる効果を奏するものである。As explained above, this idea involves providing a movable cover plate separate from the door frame on the part of the door frame that faces the surface lock of the door to which the surface lock is attached, and using this movable cover plate as a member. By holding the door frame with a bent plate formed in a trapezoidal shape through the door frame, earthquake resistance can be imparted to the door frame with an extremely simple structure and at low cost.
