Further, two or more contact portions between the first fixed contact 8a and the first movable contact 10a and two contact portions between the second fixed contact 8b and the second movable contact 10b are provided.

次に、図５、６を参照しながら、乗場ドアの施錠装置における戸閉時の状態について説明する。図５は、この発明の実施の形態１に係る乗場ドアの施錠装置における戸閉時の状態を示す一部断面図である。図５では、接点用保護カバー９を切断して示している。図６は、この発明の実施の形態１に係る乗場ドアの施錠装置における戸閉時の状態を示す平面図である。   Next, a state when the door is closed in the landing door locking device will be described with reference to FIGS. FIG. 5 is a partial cross-sectional view showing a state when the door is closed in the landing door locking device according to Embodiment 1 of the present invention. In FIG. 5, the protective cover for contacts 9 is shown cut. FIG. 6 is a plan view showing a state of the landing door locking device according to Embodiment 1 of the present invention when the door is closed.

図５、６において、戸閉時には、可動ラッチ２と掛け金６とが係合して施錠を行うとともに、短絡部材４が第１固定接点８ａと第２固定接点８ｂとを短絡する。このとき、図２〜４に示した短絡部材４および接点用保護カバー９の構成により、第１可動接点１０ａおよび第２可動接点１０ｂが、２つの開口部１１ａ、１１ｂのそれぞれに挿入され、第１固定接点８ａおよび第２固定接点８ｂと接触する。   5 and 6, when the door is closed, the movable latch 2 and the latch 6 are engaged and locked, and the short-circuit member 4 short-circuits the first fixed contact 8a and the second fixed contact 8b. At this time, the first movable contact 10a and the second movable contact 10b are inserted into each of the two openings 11a and 11b by the configuration of the short-circuit member 4 and the contact protective cover 9 shown in FIGS. The first fixed contact 8a and the second fixed contact 8b are contacted.

また、第１可動接点１０ａの第１固定接点８ａとの接触部、および第２可動接点１０ｂの第２固定接点８ｂとの接触部が、それぞれ第１固定接点８ａの第１可動接点１０ａとの接触部、および第２固定接点８ｂの第２可動接点１０ｂとの接触部よりも広い平面部分を有している。   Further, the contact portion of the first movable contact 10a with the first fixed contact 8a and the contact portion of the second movable contact 10b with the second fixed contact 8b are respectively in contact with the first movable contact 10a of the first fixed contact 8a. The contact portion and the flat portion wider than the contact portion between the second fixed contact 8b and the second movable contact 10b are provided.

また、戸閉時において、接点用保護カバー９とコンタクトブレード３との間隔は、１２ｍｍ未満にされている。また、接点用保護カバー９の２つの開口部１１ａ、１１ｂのそれぞれの下端の位置は、第１固定接点８ａおよび第２固定接点８ｂの位置よりも上方に配置されている。   When the door is closed, the distance between the contact protection cover 9 and the contact blade 3 is less than 12 mm. The positions of the lower ends of the two openings 11a and 11b of the contact protective cover 9 are arranged above the positions of the first fixed contact 8a and the second fixed contact 8b.

以上のように、実施の形態１によれば、接点用保護カバーは、第１固定接点および第２固定接点に対応した２つの開口部を有し、短絡部材は、第１可動接点および第２可動接点に分岐した二股の形状を有し、戸閉時に、第１可動接点および第２可動接点が、２つの開口部のそれぞれに挿入されるようになっている。
そのため、第１固定接点および前記第２固定接点への接触を防止して、保守員の感電を予防することができる。As described above, according to the first embodiment, the contact protective cover has two openings corresponding to the first fixed contact and the second fixed contact, and the short-circuit member includes the first movable contact and the second fixed contact. It has a bifurcated shape branched to a movable contact, and the first movable contact and the second movable contact are inserted into each of the two openings when the door is closed.
Therefore, contact with the first fixed contact and the second fixed contact can be prevented, and electric shock of maintenance personnel can be prevented.

また、第１固定接点と第１可動接点との接触部、および第２固定接点と第２可動接点との接触部が、乗場ドアの進行方向に対して垂直な方向に並んでいる。
そのため、第１固定接点と第１可動接点とが接触するタイミングと第２固定接点と第２可動接点とが接触するタイミングとが一致し、一方の接触部の接点が摩耗することを防止し、信頼性を向上させることができる。The contact portion between the first fixed contact and the first movable contact and the contact portion between the second fixed contact and the second movable contact are arranged in a direction perpendicular to the traveling direction of the landing door.
Therefore, the timing at which the first fixed contact and the first movable contact are in contact with the timing at which the second fixed contact and the second movable contact are in contact with each other, and the contact of one contact portion is prevented from being worn, Reliability can be improved.

また、第１可動接点の第１固定接点との接触部、および第２可動接点の第２固定接点との接触部が、それぞれ第１固定接点と第１可動接点との接触部、および第２固定接点と第２可動接点との接触部よりも広い平面部分を有している。
そのため、第１可動接点および第２可動接点の位置が多少ずれても、接触部の接触不良を防止することができる。Further, the contact portion of the first movable contact with the first fixed contact and the contact portion of the second movable contact with the second fixed contact are respectively a contact portion between the first fixed contact and the first movable contact, and a second contact. It has a plane portion wider than the contact portion between the fixed contact and the second movable contact.
Therefore, even if the positions of the first movable contact and the second movable contact are slightly shifted, it is possible to prevent contact failure of the contact portion.

また、第１固定接点と第１可動接点との接触部、および第２固定接点と第２可動接点との接触部は、それぞれ２箇所以上設けられている。
そのため、接触部の１箇所が埃等によって接触不良を起こした場合であっても、他の接触部で導通を確保することができ、信頼性を向上させることができる。Further, two or more contact portions between the first fixed contact and the first movable contact and two contact portions between the second fixed contact and the second movable contact are provided.
Therefore, even when a contact failure occurs in one place of the contact portion due to dust or the like, conduction can be ensured at the other contact portion, and reliability can be improved.

また、戸閉時において、接点用保護カバーと絶縁体との間隔は、１２ｍｍ未満にされている。
そのため、戸閉時に作業員が第１可動接点および第２可動接点に接触することを防止し、作業員が感電することを予防することができる。Further, when the door is closed, the distance between the contact protection cover and the insulator is less than 12 mm.
Therefore, it is possible to prevent the worker from coming into contact with the first movable contact and the second movable contact when the door is closed, and to prevent the worker from getting an electric shock.

また、接点用保護カバーの２つの開口部のそれぞれの下端の位置は、第１固定接点および第２固定接点の位置よりも上方に配置され、第１可動接点および第２可動接点は、少なくとも２回折り曲げられている。
そのため、第１可動接点および第２可動接点の位置を下げることができるので、保守員の感電をさらに防止することができる。
また、エレベータの下方から第１可動接点および第２可動接点を見ることができないので、エレベータの利用者が、下方からいたずらで第１可動接点および第２可動接点を触り、感電してしまうことを防止することができる。In addition, the positions of the lower ends of the two openings of the contact protection cover are arranged above the positions of the first fixed contact and the second fixed contact, and the first movable contact and the second movable contact are at least two. It is bent once.
Therefore, since the positions of the first movable contact and the second movable contact can be lowered, it is possible to further prevent the electric shock of the maintenance staff.
In addition, since the first movable contact and the second movable contact cannot be seen from the lower side of the elevator, the elevator user touches the first movable contact and the second movable contact with mischief from the lower side, and thus an electric shock is caused. Can be prevented.

なお、上記実施の形態１では、第１可動接点１０ａおよび第２可動接点１０ｂの形状を、少なくとも２回折り曲げられた形状とし、２つの開口部１１ａ、１１ｂのそれぞれの下端の位置を、第１固定接点８ａおよび第２固定接点８ｂの位置よりも上方に配置すると説明したが、これに限定されない。   In the first embodiment, the shapes of the first movable contact 10a and the second movable contact 10b are bent at least twice, and the positions of the lower ends of the two openings 11a and 11b are set to the first. Although it has been described that it is disposed above the positions of the fixed contact 8a and the second fixed contact 8b, the present invention is not limited to this.

すなわち、既存の乗場ドアの施錠装置にも適用するために、第１固定接点および第２固定接点は部品の取り替え等をせず、短絡接点を第１可動接点および第２可動接点に分岐した二股の形状のものと交換し、第１固定接点および第２固定接点を覆うように２つの開口部を有する端子用保護カバーを取り付けることにより、保守員の感電を予防することができる。   That is, in order to be applied to an existing landing door locking device, the first fixed contact and the second fixed contact are not replaced, and the short-circuited contact is branched into the first movable contact and the second movable contact. It is possible to prevent the maintenance staff from receiving an electric shock by replacing the terminal with a terminal cover and attaching a terminal protective cover having two openings so as to cover the first fixed contact and the second fixed contact.
