Description

【０００１】
【発明の属する技術分野】
両開き扉で、子扉の戸締まりを親扉の錠と連動させて行う子扉の錠である。
【０００２】
【従来の技術】
両開きの扉の子扉を戸締まりする金物にフランス落としと、フラッシュボルトと、子扉用グレモン締まりがある。各々の特徴と問題点を説明する。
フランス落としは子扉の戸先の上端と下端に取り付ける。親扉が閉じている時は操作できず、親扉を開いて上端と下端のフランス落としを操作する。長所は親扉が施錠中は操作できない為に施錠を助ける。短所は、非常時で子扉を解放する時にパニック状況下では操作しにくい事と、掛け忘れて親扉の錠を施錠すると扉は押しただけで開いてしまう。フラッシュボルトはフランス落としの自動型のようなものであり、親扉が閉じると子扉のフラッシュボルトが突き出して子扉の戸締まりをする。長所はフランス落としと同様に親扉の錠の施錠を助ける事で、短所はフラッシュボルトの遊びによって閉じた扉が開閉方向にガタガタする事と、コジ開けや破壊に対して強度が弱い事と、親扉が開くと自動的にフラッシュボルトが解除され、子扉は押しただけで開いてしまい、子扉の係止が出来ない事である。
子扉用グレモン締まりはハンドルの操作で子扉の上下にロッド棒を突き出し、引っ込める事で外観と動作は本発明に似ているが、短所は親扉と連動しない為に、子扉用グレモン締まりで子扉を締め、親扉を閉じて施錠した状態で子扉用グレモン締まりを解放すると施錠したままで扉を押すと開いてしまい、施錠の助けにはならない。親扉にグレモン錠を使用しなければ子扉用グレモン締まりは使えない。長所は本発明に似て操作し易い位置にあるハンドルを回して扉の上下を強力に戸締まりできる事できる。フラッシュボルト以外の子扉締まりは、締め忘れて親扉を閉じて親扉の錠を施錠すると、扉を押しただけで施錠したまま扉が開いてしまう問題がある。
【０００３】
【発明が解決しようとする課題】
両開き扉の子扉を、回す又は押す又は引くの一動作だけで戸締まりし、また解除する事。小さい力で強力に作動し、扉を強固に締めつけて固定する事。コジ開けや破壊に対して大きい強度を持つ事。子扉を閉めていない時は親扉の錠を施錠できない事。親扉の錠が施錠中は子扉の締まりを解除できない事。以上の全てを同時に解決する事。
【０００４】
【課題を解決するための手段】
大型のハンドルを回す、押す、引く事で強力な上ボルトと下ボルトを子扉の上下に突き出し、枠の受けに入れる事で強力に子扉の戸締まりをし、一つの動作で戸締まりや解除を行うようにした。
上下ボルトを動かすハンドルに連動して受け塞ぎスライダーを動かす事で、上下ボルトが引っ込んでいる時は錠受け穴を塞いで親扉の錠が施錠出来なくした。上下ボルトが突き出して子扉を戸締まりしている時は錠受け穴を開いて親扉の錠が施錠できるようにした。
親扉の錠が施錠中は錠のデットボルトにより受け穴塞ぎスライダーの動きを止められて子扉の締まりを解除できなくした。
【０００５】
【発明の実施の形態】
図面に基づいて説明する。図１は請求項１記載の錠受け連動子扉ボルトで子扉を戸締まりして親扉の錠を施錠し、錠のデットボルト(13)が錠受け穴(4)から受け穴塞ぎスライダー(3)のスライダー受け穴(5)に入っている事を示す。ハンドルを操作して上ボルト(10)と下ボルト(12)が子扉の上下に突き出し、子扉の戸締まりをすると同時にスライダーカム(7)が受け穴塞ぎスライダーを上に持ち上げて親扉の錠の施錠が可能になる。この状態ではデットボルト(13)が受け穴塞ぎスライダーの動きを妨害している為に錠受け連動子扉ボルトを動かす事はできない。すなわち子扉を開ける事はできない。親扉の錠を解錠する事で、デットボルトが引っ込み、操作が可能となり、子扉を開ける事ができる。
図２は錠受け連動子扉ボルトの状態毎の部品の動きを説明する縦断面図である。Ａは上下ボルトを引っ込め、受け穴塞ぎスライダーが錠受け穴(4)を塞いだ図である。この状態では親扉の施錠はできない。Ｂは上下ボルトを突き出し、錠受け穴の塞ぎを解いた図である。この状態で施錠が可能となる。Cは施錠状態である。この状態では受け塞ぎスライダーは動かす事ができず、錠受け連動子扉ボルトは操作できず、子扉を開く事ができない。
図３は図２の受け塞ぎスライダーと錠受け穴の動きを説明する割形斜視図である。錠受けを割って示している。Aは図２Aの状態であり、Bは図２Ｂの状態である。
図４は錠受け穴(20)を、ハンドル軸に組み付けた受け穴塞ぎ(17)を設けたハンドル軸カム(16)で開閉する請求項３を説明するものである。Aは錠受け穴(20)を受け穴塞ぎで塞いだ図であり、Bは開いたものである。
図５は受け穴塞ぎスライダーを錠受け(22)に代え、錠受けベース(21)と組み合わせた請求項２の説明図である。Aは錠受け(22)と錠受けベース(21)を組み合わせたものを前方から斜視したもので、錠受け穴(23)は下がった位置にあり、この位置では親扉の錠は施錠できない。BはAの後方から斜視したものである。上下ボルトに連動し、錠受けを上下に動かして錠受け穴位置を上下に動かす事で、錠受け穴が下にある時は親扉の錠が施錠できず、上に上がった時に施錠できる。錠受け穴が塞さがれない事で指を挟む危険が解消される。請求項１記載の錠受け(2)の錠受け穴(4)を上下に大きく開けたものでも同じ効果となる。
図６は押して上下ロッドを解除し、受け穴塞ぎスライダーを動かす請求項１記載の錠受け連動子扉ボルトの変形例である。
図１ではロッドカム(8)、上下ロッド(9)(11)、上下ボルト(10)(12)を扉の表面に図示しているが扉の内部に納めても良く、ハンドル(6)は左右回転構造となっているが、上下に上げ下げする構造でも同様に動かす事ができる。錠受け連動子扉ボルトの最大の特徴は、子扉の上下ボルトを突き出していない解除状態では親扉の錠を施錠できず、上下ボルトを突き出して子扉を戸締まりしている時だけ施錠でき、親扉の錠を施錠している間は錠受け連動子扉ボルトの操作ができずに子扉を開けられない事である。その１式が請求項１であり、親扉と子扉の操作を連動させる変形機構が請求項２と３である。
ハンドルの向きはハンドル軸の断面形状を四角や六角にする事により、ハンドル軸受けに差し込む角度を変えて向きを変える。ハンドルの回転角度に40°前後の遊び角度を設けることでハンドルの向きを常に水平に向ける事もできる。
【０００６】
【発明の効果】
錠受け連動子扉ボルトを、外部回り出入り口の両開き扉の子扉に取り付ける。建物の外回りでは常に風圧があり、よほどしっかりした戸締まりのできる金物でないと風の為に扉がガタガタと動く。フラッシュボルトではガタつきが多く、フランス落としでもガタつきが見られる。両方共に扉を締め付けて固定する機能は無い。錠受け連動子扉ボルトを取り付けた扉ではしっかりと強力に扉を締め付けて戸締まりできる。
火災時の避難に於いては、親扉の錠を解除した後はハンドルを回しただけで子扉を開けることができる。フラッシュボルトでは子扉を解除する操作が不要のためより避難しやすいが、平時の親扉の開閉に合わせて子扉も開いてしまい、不便である。フランス落としでは戸先の上と下の操作が必要で、避難には向かない。それ以外の金物で子扉を戸締まりした場合は、親扉の錠を施錠していても子扉の締まりを解除して、扉を開く方向に押せば親子扉共に開いてしまう。また子扉の締まりを忘れて親扉を閉じ、施錠した場合も同様に扉を押すと施錠したまま扉が開いてしまう。親子の両扉にグレモン締まりを取り付けた場合は、子扉のグレモン締まりを解除しても親扉が開く事は無いが子扉の締め付けは無くなる。子扉のグレモン締まりにもシリンダー錠を取り付けてキーで操作すれば解決するが、親子扉の両方をキーで操作する必要が生ずる。グレモン締まり並の締め付け強度を持つ錠受け連動子扉ボルトを子扉に取り付ける事で全てが解決する。

BACKGROUND OF THE INVENTION
It is a lock of a child door that is a double door and locks the door of the child door in conjunction with the lock of the parent door.
[0002]
[Prior art]
There are two types of hardware that close the child doors of double doors: a French drop, a flash bolt, and a gremon lock for the child doors. Each feature and problem will be explained.
The French drop is attached to the top and bottom edges of the child door. Cannot be operated when the main door is closed. Open the main door and operate the French drop at the top and bottom. The advantage is that it can be locked because the main door cannot be operated while it is locked. Disadvantages are that it is difficult to operate in a panic situation when releasing the child door in an emergency, and if you forget to lock and lock the parent door, the door will open just by pressing. The flash bolt is like a French drop automatic type. When the main door closes, the flash bolt of the child door protrudes and the child door is locked. The advantage is to help lock the lock on the parent door as well as the French drop, the disadvantage is that the door closed by the play of the flash bolt rattles in the opening and closing direction, and the strength against weakness opening and destruction is weak, When the main door is opened, the flash bolt is automatically released, and the child door is opened only by pushing, and the child door cannot be locked.
The glemon tightening for the child door is similar to the present invention in that the appearance and operation is similar to the present invention by pushing the rod rod up and down the child door by operating the handle, but the disadvantage is not interlocked with the parent door, so the glemon tightening for the child door When the child door is closed and the main door is closed and locked, the child door gremon tightener is released, and the door is opened when the door is locked while it is locked. If you don't use a gremon lock on the main door, you can't use the cremon lock for the child door. The advantage is that the upper and lower sides of the door can be strongly locked by turning the handle at a position that is easy to operate, similar to the present invention. If the child doors other than the flash bolts are forgotten to be tightened and the parent door is closed and the parent door is locked, there is a problem that the door opens while being locked only by pushing the door.
[0003]
[Problems to be solved by the invention]
The door of the double door should be locked and released with a single action of turning, pushing or pulling. It works powerfully with a small force, and tightens and fixes the door firmly. Has high strength against cracking and breaking. When the child door is not closed, the parent door cannot be locked. The child door cannot be released while the main door is locked. Solve all the above simultaneously.
[0004]
[Means for Solving the Problems]
By turning, pushing, and pulling a large handle, the upper and lower bolts are pushed up and down the child door, and put into the frame holder to lock the child door tightly. I did it.
By moving the receiving slider in conjunction with the handle that moves the upper and lower bolts, when the upper and lower bolts are retracted, the locking holes are closed and the lock on the parent door cannot be locked. When the upper and lower bolts protrude and the child door is locked, a lock receiving hole is opened to lock the parent door.
While the lock on the main door is locked, the dead hole of the lock is closed by the lock bolt of the lock, and the child door can no longer be released.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
This will be described with reference to the drawings. FIG. 1 shows a lock door interlocking child door bolt according to claim 1 to lock the child door by locking the child door, and the lock dead bolt (13) is inserted into the receiving hole closing slider (3) from the lock receiving hole (4). ) Is in the slider receiving hole (5). By operating the handle, the upper bolt (10) and lower bolt (12) protrude above and below the child door to lock the child door, and at the same time, the slider cam (7) closes the receiving hole and lifts the slider upward to lock the main door. Can be locked. In this state, since the dead bolt (13) closes the receiving hole and obstructs the movement of the slider, the lock interlock door bolt cannot be moved. That is, the child door cannot be opened. By unlocking the lock on the main door, the dead bolt is retracted and can be operated, and the child door can be opened.
FIG. 2 is a longitudinal sectional view for explaining the movement of components for each state of the lock receiver interlocking door bolt. A is a view in which the upper and lower bolts are retracted, and the receiving hole closing slider closes the lock receiving hole (4). In this state, the main door cannot be locked. B is a view in which the upper and lower bolts are projected to close the lock receiving hole. Locking is possible in this state. C is locked. In this state, the receiving slider cannot be moved, the lock interlocking child door bolt cannot be operated, and the child door cannot be opened.
FIG. 3 is a split perspective view for explaining the movement of the receiving slider and the lock receiving hole of FIG. The lock holder is broken. A is the state of FIG. 2A, and B is the state of FIG. 2B.
FIG. 4 explains claim 3 in which the lock receiving hole (20) is opened and closed by a handle shaft cam (16) provided with a receiving hole closing (17) assembled to the handle shaft. A is a view in which the lock receiving hole (20) is received and closed, and B is open.
FIG. 5 is an explanatory view of claim 2 in which the receiving hole closing slider is combined with a lock receiving base (21) instead of the lock receiving (22). A is a perspective view of the combination of the lock receiver (22) and the lock receiver base (21) from the front. The lock receiving hole (23) is in the lowered position, and the lock of the main door cannot be locked in this position. B is a perspective view of A from the rear. By interlocking with the upper and lower bolts, moving the lock holder up and down to move the lock hole position up and down, the lock on the main door can not be locked when the lock reception hole is down, and it can be locked when it is raised up. The danger of pinching your fingers is eliminated because the lock holes are not blocked. The same effect can be obtained even when the lock receiving hole (4) of the lock receiver (2) according to claim 1 is greatly opened up and down.
FIG. 6 shows a modified example of the lock interlocking door bolt according to claim 1, wherein the lock is moved by releasing the upper and lower rods and moving the receiving hole closing slider.
In Fig. 1, the rod cam (8), the upper and lower rods (9) and (11), and the upper and lower bolts (10) and (12) are shown on the surface of the door. Although it has a rotating structure, it can be moved in the same way even when it is raised and lowered up and down. The biggest feature of the lock interlocking child door bolt is that the lock on the main door cannot be locked in the released state where the upper and lower bolts of the child door are not protruding, and it can be locked only when the child door is locked by protruding the upper and lower bolts. While the lock on the main door is locked, it is impossible to operate the lock interlocking child door bolt and the child door cannot be opened. The first set is Claim 1 and the deformation mechanisms for interlocking the operations of the main door and the child door are Claims 2 and 3.
The direction of the handle is changed by changing the angle to be inserted into the handle bearing by changing the cross-sectional shape of the handle shaft to square or hexagon. By providing a play angle of around 40 ° to the rotation angle of the handle, the handle can always be oriented horizontally.
[0006]
【The invention's effect】
Attach the lock interlocking child door bolt to the child door of the double door at the external doorway. There is always wind pressure around the outside of the building, and the door moves rattlingly due to the wind unless it is a hardware that can lock the door firmly. There is a lot of rattling with flash bolts, and there is also rattling even when dropped in France. Both do not have the function of tightening and fixing the door. Doors with lock interlock door bolts can be tightened firmly and strongly.
In case of fire evacuation, after unlocking the main door, the child door can be opened simply by turning the handle. With flash bolts, it is easier to evacuate because there is no need to release the child door, but it is inconvenient because the child door opens as the main door opens and closes during normal times. The French drop requires operation above and below the door and is not suitable for evacuation. When the child door is locked with other hardware, even if the parent door is locked, if the child door is unlocked and pushed in the opening direction, both the parent and child doors are opened. In addition, when the child door is forgotten to be tightened and the main door is closed and locked, when the door is pushed in the same manner, the door opens while being locked. When the gremon tightening is attached to both doors of the parent and child, the parent door will not open even if the gremon tightening of the child door is released, but the child door will not be tightened. It can be solved by attaching a cylinder lock and operating it with the key to tighten the glemon of the child door, but it becomes necessary to operate both the parent and child doors with the key. All can be solved by attaching a lock interlocking door bolt with a tightening strength comparable to that of a gremon.
