したものである。(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a structure in which a child door is provided above and below, or at least on one side of, a child door of a double-opening door in a direction perpendicular to the floor surface. When the door is closed, a lock case fitted with a lock rod is installed so that it comes into contact with the frame or a catch provided on the frame and retreats, and when the lock moves back, it is pushed by the lock rod or Due to the biasing force applied to itself, it protrudes from the rotating side end of the child door in the direction where it comes into contact with the rotating side end of the main door, and when the child door is closed after the main door is closed, it comes into contact with the main door. Providing a trigger that touches and retreats, and interlocking each other so that when the lock or trigger moves back, the lock directly or indirectly pushes the trigger or the trigger pushes the lock and causes the other party to protrude, The lock is such that when a side pressure is applied to the child door in the opening direction, a force is applied to the lock in the backward direction, and the force in the backward direction of the lock is in a direction that causes the trigger to protrude. There is a conversion device that converts the force into force, so when both doors of a double-opening door are closed, the trigger on the child door comes into contact with the main door and moves back, and the lock lever is pushed as the trigger moves back. Since the lock lever cannot be moved back until the main door is moved and engaged with the protruding receiving hole, the locked state is ensured. Next, when the parent door is opened, the trigger is in a state where it can be ejected, allowing the lock lever to retract, allowing the child door to be opened, and with both doors closed. When lateral pressure is applied in the opening direction, the force acts in the direction of retracting the lock lever, and further acts in the direction of protruding the trigger by the conversion device, so as soon as the main door opens, the trigger will be released. The protruding lock lever is also reliably retracted, and the child door can also be automatically and reliably opened.

方向への力を受ける。 The operation of the third embodiment having the above configuration will be explained. Figure 5 shows the solid lines a, b, and c when both doors are closed, and the trigger 4 is pushed by the main door D, rotates and retreats into the trigger case 2', and the trigger 4 is pushed back into the trigger case 2'. The end retracts the pushing rod 4'. As the pushing rod 4' retreats, the cam 9 is rotated counterclockwise in FIG. Due to the movement, the locking member 8 and the locking rod 3 are pushed up together, and the locking rod 3 protrudes and fits into the receiving metal fitting 5 provided on the frame, thereby fixing the child door D' to the frame. In other words, it becomes locked. In this state, when lateral pressure is applied to the child door D' in the opening direction, the back surface 3b of the lock 3 comes into contact with the receiving metal fitting, and the lock 3 moves counterclockwise in FIG. 5b with the shaft 3e as a fulcrum. try to reverse it. At this time, the locking member 8 is pushed by the rear end of the locking rod 3 and receives a force in the backward direction, but cannot move back because its locking portion 8a is engaged with the locking portion 10a of the locking member 10. . In addition, the locking member 10 is caused by the retraction force of the locking member.
The slope 10c of the contact portion between the locking member 10 and the sliding rod 11 receives rotational force in the counterclockwise direction about the shaft 3e as a fulcrum.
and 11c, the sliding rod 11 receives a force in its backward direction.

しかしながら、該摺動杆１１は前記トリガー４
が突出しない限り後退できないので、錠杆３は後
退できず突出状態を保持し、子扉D′は枠に固定
された状態を保持する。 However, the sliding rod 11 is
Since the lock rod 3 cannot retreat unless it protrudes, the lock rod 3 cannot retreat and maintains the protruding state, and the child door D' maintains the state fixed to the frame.

次に、親扉Ｄを開放するとトリガー４は突出可

で、子扉D′も開けることができる。 Next, when the main door D is opened, the trigger 4 becomes able to protrude, so the sliding rod 11 retreats as shown in FIG. 6, and the locking member 10 rotates to release the engagement with the locking member 8. Therefore, the locking member 8 moves back and the locking rod 3 is reversed. When the locking rod 3 is reversed, the back surface 3b becomes a slope and slides back due to the lateral pressure, so that the child door D' can also be opened.

び摺動杆１１の作用以外同じである。(Fourth Embodiment) FIGS. 8a and 8b show a fourth embodiment, in which the locking member 10 and the sliding rod 11 are simplified in structure in the third embodiment. That is, the lock member 8 is brought into contact with the rear end of the lock rod 3, and the rear end of the lock member 8 is brought into contact with the cam 9. 8, and the retraction of the locking member 8 is converted into a protruding force of the trigger 4 via a cam 9. Its function is the same as that of the third embodiment except for the function of the locking member 10 and the sliding rod 11.

D′のガタ付きの原因となる。 In addition, to explain the operational difference between the fourth embodiment and the third embodiment, when in use, the trigger 4 protrudes by the gap between the main door D and the child door D', and the trigger 4 protrudes depending on the amount of protrusion. Since the lock rod 3 moves backward, a gap is created between the shaft 3e provided in the lock rod 3 and the guide hole 2b provided in the case 2. At this time, when lateral pressure is applied to the lock lever 3, in the case of the fourth embodiment shown in FIGS. , the lock lever 3 will be slightly reversed. This is a child door
This will cause D′ to become loose.

ないのである。 In the third embodiment shown in FIG. 5, the child door D' is prevented from rattling, that is, even if a gap occurs between the shaft 3e and the guide hole 2b, it is integrally held by the locking rod 3. Since the locking member 10 is engaged with the locking member 8, the locking member 8 receives a force in the backward direction due to the force in the reversal direction of the lock rod 3, and the locking member 10 also receives a force in the backward direction. Therefore, the shaft 3e, which also serves as a rotation shaft of the locking member 10, cannot move upward, and the locking rod 3 does not reverse. In other words, the child door D' does not rattle.

親扉が阻止する事になる。(Effects of the Invention) The present invention has the above-described configuration, and the lock rod provided on one child door of a double-opening door is retracted by lateral pressure in the opening direction to the child door, and The retraction force of the lock lever is converted into the protrusion force of the trigger by a conversion device, so that the trigger is interlocked and protruded facing the other main door, and when the trigger is retracted, the lock lever is interlocked and protruded. When the main door is closed after the child door is closed, the trigger is retracted by the main door, the locking rod projects and fits into the receiving metal fitting, and the child door is locked. When a large lateral pressure is applied to the child door in the opening direction, that lateral pressure causes a force in the backward direction to act on the lock, and the backward force of the lock is transferred to the main door by the conversion device. The side pressure that is converted into the protruding force of the protruding trigger is blocked by the other main door.

なる。しかも、子扉に作用する開放方向への側圧
が大きければ大きい程、錠杆の後退力は大きくな
るので、トリガーの突出を阻止している親扉が開
放されさえすれば、子扉はより確実にしかも素早
く開放することができる。 Therefore, when the main door that prevents the trigger from protruding is opened, the trigger can be protruded. That is, the lock lever can be moved back and the child door can be opened. Moreover, the greater the lateral pressure acting on the child door in the opening direction, the greater the retraction force of the lock lever, so as long as the main door that prevents the trigger from protruding is opened, the child door will be more secure. Moreover, it can be opened quickly.

しかも、その側圧は従来の如く錠杆が全て支え
るのではなく、錠杆およびトリガーを介して親扉
が支えることになるので非常に大きな側圧にも耐
え得る。 Furthermore, the lateral pressure is not entirely supported by the lock rod as in the conventional case, but is supported by the main door via the lock rod and the trigger, so that it can withstand extremely large lateral pressure.

従つて、本発明に係る両開用の錠をビル等の非

とができるという、大きな効果を奏する。 Therefore, if the double-opening lock according to the present invention is used for double-opening doors installed at emergency exits of buildings, etc., even when large lateral pressure is applied to the door due to a rush of people evacuating in the event of an emergency such as a fire. , it can withstand the side pressure, and if the main door is opened, the child door can also be opened reliably. In other words, it is possible to solve problems that could not be solved with conventional locks for double-opening doors, and it has the great effect of allowing a large number of people to evacuate quickly in an emergency, and preventing disasters from occurring.

して傷を付ける恐れもない。 In addition, by constantly biasing the lock lever in the backward direction with a spring or the like, the lock lever can be reliably moved back even when no lateral pressure is applied, and the slave door can be opened.
Furthermore, since the lock rod is always retracted into the case when the child door is open, there is no risk of the lock rod coming into contact with the upper frame or the floor and causing damage.

また、万一バネ等の破損によつて錠杆が突出し
たまま子扉が開いて、錠杆が上枠や床に当接した
場合でも、錠杆はその斜面からの作用あるいは反
転して後退するようにしてなるから、上枠や床を
傷付ける恐れがない。 Additionally, in the unlikely event that the child door opens with the lock protruding due to damage to the spring, etc., and the lock comes into contact with the upper frame or the floor, the lock will be pushed back by the action from the slope or reversed. There is no risk of damaging the upper frame or floor.

する。 Furthermore, as described in claim 5, the locking member that prevents the locking rod from being reversed is locked by a locking member that is integrally and rotatably held on the locking rod, and the locking member is If the sliding rod prevents the rotation of the locking member and controls the engagement and disengagement between the locking member and the locking member, there will be a gap between the two opening doors, and the trigger will move by that amount. Even when the lock is protruded and the lock is retracted, the lock does not turn over and the door does not rattle.
