Description

本発明は、係合手段によりかごドア及び乗場ドアを係合して開閉するエレベータのドア装置に関する。   The present invention relates to an elevator door device that engages and opens and closes a car door and a landing door.

一般に、エレベータは、かご側に、かごの開口を覆うように配設されるかごドアと、駆動力を付与する駆動手段と、かごドアのレール枠に配置されるかごドア駆動用レール及び係合手段駆動用レールと、係合手段駆動用レールに沿って移動する係合手段と、おもりやばね等によりかごドアに自閉力を付与する自閉力付与手段とを備えるとともに、乗場側に、乗場の開口を覆うように配設されるとともにかごドアと対向可能な乗場ドアと、係合手段と係合可能な係合部と、おもりやばね等により乗場ドアに自閉力を付与する自閉力付与手段とを備え、係合手段によりかごドア及び乗場ドアを係合して開閉する。   In general, an elevator is provided on a car side so as to cover a car opening, a driving means for applying a driving force, a car door driving rail and an engagement arranged on a rail frame of the car door. Means driving rail, engaging means moving along the engaging means driving rail, and a self-closing force applying means for applying a self-closing force to the car door by a weight, a spring or the like, and on the landing side, A landing door that is disposed so as to cover the opening of the landing and that can face the car door, an engagement portion that can be engaged with the engagement means, and a self-closing force applied to the landing door by a weight or a spring. A closing force applying means for engaging and closing the car door and the landing door by the engaging means.

また、一般に、かご側にはドアロック手段は設けておらず、乗場側のみに係合手段により解錠及び施錠される乗場ドアロック手段が設けられている。ドア開き動作は、自閉力付与手段によりドアに自閉力が加わっている状態で、かごドアに駆動手段により開き方向に駆動力が加えられ、係合手段を介して乗場ドアロック手段に駆動力が伝わり、乗場ドアロック手段が解錠されることで行なわれる。ドア閉じ動作も同様に、自閉力付与手段によりドアに自閉力が加わっている状態で、かごドアに駆動手段により閉じ方向に駆動力が加えられ、係合手段を介して乗場ドアロック手段に駆動力が伝わることで行なわれる。この際、乗場ドアには自閉力が加わっているため、乗場ドアはかごドアに良好に追従し、乗場ドアロック手段は戸閉完了後の係合手段の係合が外れた状態で確実に施錠される。このようなエレベータにあっては、前述したようにかごドアにはドアロック手段は設けておらず、かご走行中にかご内から故意にかごドアがこじ開けられると、かごが急停止し、乗客がかご内に閉じ込められたり、こじ開けたかごドアから昇降路内に転落したりする危険があった。   In general, door locking means is not provided on the car side, and landing door locking means that is unlocked and locked by the engaging means is provided only on the landing side. In the door opening operation, the self-closing force is applied to the door by the self-closing force applying means, and the driving force is applied to the car door in the opening direction by the driving means, and the landing door lock means is driven through the engaging means. Power is transmitted and the landing door lock means is unlocked. Similarly, in the door closing operation, the self-closing force is applied to the door by the self-closing force applying means, and the driving force is applied to the car door in the closing direction by the driving means. This is done when the driving force is transmitted to. At this time, since the landing door is subjected to a self-closing force, the landing door follows the car door well, and the landing door lock means is securely engaged with the engagement means disengaged after the door is closed. Locked. In such an elevator, as described above, the car door is not provided with a door locking means, and if the car door is intentionally opened from inside the car while the car is running, the car suddenly stops, There was a danger of being trapped in the car or falling into the hoistway from the car door that was opened.

このため、従来、かご走行中にかごドアを施錠するかごドアロック手段として、フック側がスプリングにより上方へ引き上げられてドアロックを解錠するとともに、ソレノイドが励磁されることで反フック側が吸引されドアロックを施錠するものや（例えば、特許文献１参照）、係合手段に設けられたフック付レバーが捻りばねにより引き上げられることで施錠するとともに、かごが正常着床範囲では駆動手段によりかごドアを開く際に乗場ドア自閉力の反力が加わり、機械的にロックを解錠するものが提案されている（例えば、特許文献２参照）。
特開平２−８９７９３号公報（第３頁、第３図） 特開平９−７７４３８号公報（段落番号００１１〜００２０、図２） For this reason, conventionally, as a car door lock means for locking the car door while the car is running, the hook side is pulled upward by a spring to unlock the door lock, and the solenoid is energized so that the anti-hook side is sucked and the door For locking the lock (see, for example, Patent Document 1), the lever with a hook provided in the engagement means is pulled up by a torsion spring, and the car door is locked by the drive means in the normal landing range. There has been proposed a mechanism in which a reaction force of a landing door self-closing force is applied when the door is opened and the lock is mechanically unlocked (for example, see Patent Document 2).

しかしながら、前述した特許文献１に記載のものでは、停電や断線が発生した場合、ソレノイドへの通電が遮断されドアロックは開錠状態となる。このため、万一、停電や断線が発生し、かつかごが正常着床範囲外に停止したとき、乗客がかごドアを開け昇降路内へ転落する恐れがある。   However, in the thing of the patent document 1 mentioned above, when a power failure or a disconnection generate | occur | produces, electricity supply to a solenoid will be interrupted | blocked and a door lock will be in an unlocking state. For this reason, if a power outage or disconnection occurs and the car stops outside the normal landing range, the passenger may open the car door and fall into the hoistway.

また、前述した特許文献２に記載のものでは、フックを引き上げる捻りばねのばね力は、乗場ドア自閉力の反力よりも小さくしなければならないため、フック付レバーの剛性を上げることができないという問題があった。   Moreover, in the thing of patent document 2 mentioned above, since the spring force of the torsion spring which pulls up a hook must be made smaller than the reaction force of landing door self-closing force, the rigidity of a lever with a hook cannot be raised. There was a problem.

本発明は、前述した従来技術における実状からなされたもので、その目的は、かごドアロック手段として、ソレノイドを要することなく、かつ十分な強度を施錠部に持たせることのできるエレベータのドア装置を提供することにある。   The present invention has been made from the above-described actual state of the prior art, and an object of the present invention is to provide an elevator door device that can provide a locking portion with sufficient strength without requiring a solenoid as a car door lock means.

To do.

一方、図２に示すかごドア１Ｌ、１Ｒの完全開扉状態から、駆動手段２のモータ２１により駆動ベルト２４を介して係合手段６が閉方向に駆動されると、係合手段６の閉じ側係合ローラ１５ｄへの押圧が解除され、フックばね１５ｆのばね力によりドアロックフック１５ｃは施錠方向に回動される。このときフックストッパ１５ｈがドアロックフック１５ｃの反フック側に当接してドアロックフック１５ｃを位置決めする。この状態からさらに駆動ベルト２４を介して閉方向に駆動力が付与され、かごドア１Ｌ、１Ｒはかごドア駆動用レール４及びドア敷居８に案内されつつ閉動作し、完全開扉状態となるときにドアロックフック１５ｃがドアロック受け１５ｇに当接して、ドアロックフック１５ｃの端部に形成されたテーパにより一旦開錠方向に回動するとともに、さらに閉方向に移動してかごドア１Ｌ、１Ｒが完全閉となった時点で再びフックばね１５ｆのばね力によりドアロックフック１５ｃがドアロック受け１５ｇに係合し、施錠される。なお、乗場ドア２０はかごドア１Ｌ、１Ｒと同期して閉扉するとともに、同等の構造を有する乗場ドアロック手段２３も同様の手順で施錠される。また、かご内から乗客がかごドア１Ｌ、１Ｒをこじ開けようしても、閉じ側係合ローラ１５ｄに戸開力は伝わらない構造となっており、解錠することはできない。さらに、正常着床範囲内で停電し駆動手段２による戸開力が与えられない場合でも、ドアロックフック１５ｃに設けられた解錠レバー１５ｉを専用キー３０により引き上げることで解錠することができる。   On the other hand, when the engaging means 6 is driven in the closing direction by the motor 21 of the driving means 2 via the driving belt 24 from the fully opened state of the car doors 1L and 1R shown in FIG. The pressure on the side engagement roller 15d is released, and the door lock hook 15c is rotated in the locking direction by the spring force of the hook spring 15f. At this time, the hook stopper 15h comes into contact with the opposite side of the door lock hook 15c to position the door lock hook 15c. When the driving force is further applied in the closing direction from this state via the driving belt 24, the car doors 1L and 1R are closed while being guided by the car door driving rail 4 and the door sill 8, and the door is completely opened. The door lock hook 15c comes into contact with the door lock receiver 15g and is temporarily rotated in the unlocking direction by a taper formed at the end of the door lock hook 15c, and further moved in the closing direction to move the car door 1L, 1R. When the door is completely closed, the door lock hook 15c is engaged with the door lock receiver 15g by the spring force of the hook spring 15f again and locked. The landing door 20 is closed in synchronization with the car doors 1L and 1R, and the landing door locking means 23 having an equivalent structure is also locked in the same procedure. Further, even if a passenger tries to open the car doors 1L and 1R from the inside of the car, the door opening force is not transmitted to the closing side engaging roller 15d, and the car door cannot be unlocked. Furthermore, even when a power failure occurs within the normal landing range and the door opening force by the driving means 2 is not given, the unlocking lever 15i provided on the door lock hook 15c can be unlocked by pulling up with the dedicated key 30. .

本実施形態によれば、エレベータ走行中にかごドア１Ｌ、１Ｒを施錠するかごドアロック手段１５は係合手段６により駆動されることから、かごドアロック手段１５としてソレノイドを要することなく、機械的に解錠及び施錠動作を行うことが可能となる。また、かごドアロック手段１５は大きな駆動力を伝達する係合手段６により駆動されることから、施錠力を大きな値に設定することが可能となり、十分な強度を施錠部に持たせることができる。これによって、エレベータの安全性の向上を図ることができる。さらに、乗場側の構造は従来と同様のままでよく、比較的容易に本発明を適用することができる。   According to the present embodiment, the car door lock means 15 that locks the car doors 1L and 1R during the elevator travel is driven by the engaging means 6, so that the car door lock means 15 does not require a solenoid and can be mechanically operated. It is possible to perform unlocking and locking operations. Further, since the car door lock means 15 is driven by the engaging means 6 that transmits a large driving force, the locking force can be set to a large value, and the locking portion can have sufficient strength. . As a result, the safety of the elevator can be improved. Furthermore, the structure on the landing side may remain the same as the conventional one, and the present invention can be applied relatively easily.
