【考案の詳細な説明】 この考案は面付錠を取付けられた扉が、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 allows the door to be opened without any trouble even when a door with a 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、面付錠の縦方向端面とこれに対向す
る扉枠の端面との最小隙間ａ。Generally, the relationship between a door to which a surface-mounted lock is attached and a door frame is as shown in FIG. 1, as shown in FIG.

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し移
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 slightly relative to each other due to vibrations such as these, they easily come into contact with each other, making it impossible to open the door without any problems.

この考案は、上記欠点を解消した面付錠を備えた扉に対
す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 for a door equipped with a surface lock that eliminates the above-mentioned drawbacks.

第２図以下に示す実施例について説明すれば１は内側に

３ｂとの間の最小隙間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 facing this is the gap l between the vertical end surface 2a of the surface-mounted lock 2 and the vertical end surface 3a of the door frame 3 facing this. It is formed to be larger than the minimum gap a between it and another end face 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.

きくなるように形威しであるので、従来のように扉１の
端面１ａが扉枠３の端面３ａに直接接触して損傷される
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 is designed to be larger than the minimum gap a between the end surface 2a of the surface-mounted lock 2 and the end surface 3b of the door frame 3, so that the end surface 1a of the door 1 does not meet the end surface 3a of the door frame 3 as in the conventional case. It can prevent damage caused by direct contact.

扉１と扉枠３との最初の接触は、扉１が扉枠３の方向に

方向に移動させて、地震などの振動による扉１の変位を
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, and the end surface 2a of the surface lock 2 is brought into contact with the door frame 3 as shown in FIG. When the door 1 contacts the movable cover plate 11 shown in FIG. 1 and continues to move toward the door frame 3,
The surface-mounted lock 2 moves the movable cover plate 11 together with the movable catch 12 and the cylindrical case 15 in the direction of the guide rod 17 against the biasing force of the spring 16 to prevent displacement of the door 1 due to vibrations such as earthquakes. It can be absorbed.

の取付中心までの距離ｌ。Therefore, the length of the displacement absorption of the door 1 by the spring pressing member 14 consisting of the cylindrical case 15, the spring 16, and the guide rod 17 is set to be approximately equal to the gap difference la between the gap l and the gap a. If the surface-mounted lock 2 and the end surface 3b of the door frame 3 are
Distance l to the installation center.

、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、第３図に示すような円形の面付錠２の場合には、

なくなる。In addition, in the case of a circular surface lock 2 as shown in Fig. 3,
The length of the movable cover plate 11 may be determined to be longer than the chord length m of the surface-mounted lock 2, but when using a rectangular surface-mounted lock, the size of the movable cover plate 11 should be set to be longer than the length m of the chord of the surface-mounted lock 2. If the lock is not set to be larger than the dimension in the height direction (corresponding to the dimension h in FIG. 3) and the dimension in the forward direction (corresponding to the dimension t in FIG. 2), the movable cover plate 11 cannot be moved into the partition member 5 against the spring pressing member 14.

第８図はこの考案の他の実施例を示すもので、可動蓋板
１１が扉枠３の折曲げフランジ部３ｅ、３ｆ内に摺動可
能に取付けられた場合を示す。FIG. 8 shows another embodiment of this invention, in which the movable cover plate 11 is slidably attached within the folded flange portions 3e, 3f of the door frame 3.

効果をも良くすることができる。When the movable cover plate 11 is held in this way, the seismic performance by sliding the movable cover plate 11 into the door frame 3 can be more smoothly exhibited, and the bending flange portion 3e
This action prevents the movable cover plate 11 from being moved into the door frame 3 from the gap l between the end surface 1a of the door 1 and the end surface 3a of the door frame 3 using an appropriate tool, and prevents the movable cover plate 11 from being moved into the door frame 3 using an appropriate tool. 2 can also improve the locking effect.

１実施例の場合と同じ構成である。FIG. 9 shows still another embodiment of this invention, in which the bent flange 11 of the gasket insertion groove 8 of the movable lid plate 11 is shown.
The structure is the same as that of the first embodiment except that the fixed lid 7 is provided so as to be in contact with the door 1 side of b.

このように可動蓋板１１の扉１側に固定蓋金７を設けた
場合には、扉枠３に耐震性能を付与することができると
ともに、面付錠２による施錠効果を良くして防犯性を高
めることか゛できる。When the fixed cover plate 7 is provided on the door 1 side of the movable cover plate 11 in this way, it is possible to impart earthquake resistance to the door frame 3, and improve the locking effect of the surface lock 2, thereby improving security. It is possible to increase the

第１０図はこの考案のさらに他の実施例を示すもので、
可動蓋板１１にパツキン挿着溝８を形成しない場合を示
す。FIG. 10 shows yet another embodiment of this invention.
A case in which the gasket insertion groove 8 is not formed in the movable lid plate 11 is shown.

このように可動蓋板１１にパツキン挿着溝８を形成しな
い場合には、扉１の内面と可動蓋板１１とのエアタイト
は悪くなるが、可動蓋板１１の構造はきわめて簡単にな

ができる。If the gasket insertion groove 8 is not formed in the movable cover plate 11 as described above, the air tightness between the inner surface of the door 1 and the movable cover plate 11 will be poor, but the structure of the movable cover plate 11 will be extremely simple. Earthquake resistance can be imparted to the door frame 3 at low cost.
