Description

本出願は、扉開閉検出装置及びエレベータに関する。 The present application relates to a door open/close detector and an elevator.

従来、例えば、扉開閉検出装置は、乗場扉の開閉状態を検出する（例えば、特許文献１）。そして、扉開閉検出装置は、第１接点部と、第１接点部に接続される弾性変形可能な弾性部と、乗場扉が開状態のときに第１接点部から離れ、乗場扉が閉状態のときに弾性部が弾性変形するように第１接点部に加圧接触する第２接点部とを備えている。 Conventionally, for example, a door opening/closing detection device detects the opening/closing state of a hall door (eg, Patent Document 1). The door opening/closing detection device includes a first contact portion, an elastically deformable elastic portion connected to the first contact portion, and an elastic portion that is separated from the first contact portion when the landing door is open and closed. and a second contact portion that presses into contact with the first contact portion so that the elastic portion is elastically deformed at the time of .

ところで、例えば、乗場扉等に振動が加えられることによって、第１接点部及び第２接点部にも振動が伝えられる。そして、第１接点部と第２接点部とが接触する状態で移動して、弾性部の弾性変形量が変化することによって、第１接点部と第２接点部とが、一時的に離れる場合がある。これにより、例えば、乗場扉が閉まっているにも関わらず、扉開閉検出装置は、乗場扉が開いたと誤検出する場合がある。 By the way, for example, when vibration is applied to the landing door or the like, the vibration is also transmitted to the first contact portion and the second contact portion. Then, when the first contact portion and the second contact portion move while in contact with each other and the elastic deformation amount of the elastic portion changes, the first contact portion and the second contact portion temporarily separate. There is As a result, for example, the door opening/closing detection device may erroneously detect that the landing door is open even though the landing door is closed.

In addition, although not particularly limited, the elastic portion 4c may be formed in the shape of a plate spring as in the present embodiment.

検出接点部４ａは、弾性部４ｃの第１端部に固定されている。特に限定されないが、検出接点部４ａは、例えば、本実施形態のように、弾性部４ｃの第１端部に直接的に固定（即ち、連結）されていてもよく、また、例えば、弾性部４ｃの第１端部に介在部を介在させて間接的に固定されていてもよい。 The detection contact portion 4a is fixed to the first end of the elastic portion 4c. Although not particularly limited, the detection contact portion 4a may be directly fixed (that is, connected) to the first end portion of the elastic portion 4c, for example, as in the present embodiment. It may be indirectly fixed to the first end of 4c by interposing an intervening portion.

また、弾性部４ｃの第２端部は、本体部４ｂに固定されている。特に限定されないが、弾性部４ｃの第２端部は、例えば、本実施形態のように、本体部４ｂに直接的に固定（即ち、連結）されていてもよく、また、例えば、本体部４ｂに介在部材を介在させて間接的に固定されていてもよい。 A second end of the elastic portion 4c is fixed to the body portion 4b.

Moreover, the restriction portion 4d is arranged below the detection contact portion 4a. The detection contact portion 4a includes a contact 4g that contacts the moving contact portion 3f and a supported portion 4h that is supported by the restricting portion 4d. When the elastic portion 4c is restored (not elastically deformed), the detection contact portion 4a is separated from the restricting portion 4d and is not supported. On the other hand, when the elastic portion 4c is elastically deformed, the detection contact portion 4a is supported by the restricting portion 4d.

これにより、弾性部４ｃがさらに弾性変形することを規制することができる。なお、検出接点部４ａは、例えば、本実施形態のように、被支持部４ｈが規制部４ｄに直接的に接触することによって支持されていてもよく、また、例えば、介在部材を介在させて間接的に接触することによって支持されていてもよい。 As a result, further elastic deformation of the elastic portion 4c can be restricted.

It may be supported by indirect contact.

本実施形態に係るエレベータ１の構成については以上の通りであり、次に、本実施形態に係る扉開閉検出装置２の動作について、図７及び図８を参照しながら説明する。 The configuration of the elevator 1 according to this embodiment is as described above. Next, the operation of the door opening/closing detection device 2 according to this embodiment will be described with reference to FIGS. 7 and 8. FIG.

乗場扉１ｆ（図２参照）が開状態であるときには、図７に示すように、移動体３が移動位置に位置しており、接点部３ｆ，４ａ同士は、互いに離れている。そして、移動接点部３ｆと検出接点部４ａとが離れていることによって、扉開閉検出装置２は、乗場扉１ｆが開状態であると検出する。 When the landing door 1f (see FIG. 2) is open, as shown in FIG. 7, the moving body 3 is positioned at the moving position, and the contact portions 3f and 4a are separated from each other. The door opening/closing detection device 2 detects that the landing door 1f is in the open state because the moving contact portion 3f and the detection contact portion 4a are separated from each other.

一方、乗場扉１ｆが閉状態であるときには、図８に示すように、移動体３が待機位置に位置しており、接点部３ｆ，４ａ同士は、互いに接触している。そして、移動接点部３ｆが一対の検出接点部４ａ，４ａに跨って接触することによって、一対の検出接点部４ａ，４ａが、移動接点部３ｆを介して電気的に接続されるため、扉開閉検出装置２は、乗場扉１ｆが閉状態であると検出する。 On the other hand, when the landing door 1f is closed, as shown in FIG. 8, the moving body 3 is positioned at the standby position, and the contact portions 3f and 4a are in contact with each other. Since the pair of detection contact portions 4a, 4a are electrically connected via the moving contact portion 3f by contacting the moving contact portion 3f across the pair of detection contact portions 4a, 4a, the door is opened and closed. The detection device 2 detects that the landing door 1f is closed.

このとき、加力部３ｅの弾性部材が、弾性変形している状態であり、移動体３の加力部３ｅが、回動部３ｂに力を加えているため、検出体４の弾性部４ｃは、弾性変形している。これにより、移動接点部３ｆには、加力部３ｅの力により下向きの力が加えられ、検出接点部４ａには、弾性部４ｃの弾性復元力により上向きの力が加えられている。 At this time, the elastic member of the force applying portion 3e is elastically deformed, and the force applying portion 3e of the moving body 3 applies force to the rotating portion 3b. is elastically deformed. As a result, downward force is applied to the moving contact portion 3f by the force of the force applying portion 3e, and upward force is applied to the detection contact portion 4a by the elastic restoring force of the elastic portion 4c.

したがって、移動接点部３ｆと検出接点部４ａ，４ａとが、互いに加圧接触しているため、例えば、扉開閉検出装置２に振動が加わった場合でも、移動接点部３ｆと検出接点部４ａ，４ａとが離れることを抑制することができる。なお、加力部３ｅの力が弾性部４ｃの弾性復元力よりも大きいため、検出接点部４ａは、規制部４ｄに止められて支持されている。 Therefore, since the moving contact portion 3f and the detecting contact portions 4a, 4a are in pressure contact with each other, even if the door opening/closing detection device 2 is subjected to vibration, for example, the moving contact portion 3f and the detecting contact portions 4a, 4a, 4a can be suppressed from being separated. Since the force of the force applying portion 3e is larger than the elastic restoring force of the elastic portion 4c, the detection contact portion 4a is stopped and supported by the restricting portion 4d.

しかしながら、移動接点部３ｆと検出接点部４ａ，４ａとが互いに加圧接触していても、扉開閉検出装置２に大きな振動が加わった場合に、移動接点部３ｆと検出接点部４ａ，４ａとが一時的に離れる虞がある。なお、移動接点部３ｆ又は検出接点部４ａ，４ａの何れか一方のみが移動することを規制された場合においては、他方が振動した場合に、移動接点部３ｆと検出接点部４ａ，４ａとが一時的に離れる虞がある。 However, even if the moving contact portion 3f and the detecting contact portions 4a, 4a are in pressure contact with each other, when a large vibration is applied to the door open/close detecting device 2, the moving contact portion 3f and the detecting contact portions 4a, 4a may is likely to leave temporarily. In the case where only one of the moving contact portion 3f and the detecting contact portions 4a, 4a is restricted from moving, the moving contact portion 3f and the detecting contact portions 4a, 4a may move when the other vibrates. There is a risk of leaving temporarily.

それに対して、移動接点部３ｆと検出接点部４ａ，４ａとが接触する状態において、規制部４ｄは、検出接点部４ａ，４ａを止めることによって、移動接点部３ｆ及び検出接点部４ａ，４ａの両方を支持している。これにより、移動接点部３ｆ及び検出接点部４ａ，４ａの両方が移動することを規制することができるため、弾性部４ｃの弾性変形量が変化することを規制することができる。 On the other hand, in a state where the moving contact portion 3f and the detecting contact portions 4a, 4a are in contact with each other, the restricting portion 4d stops the detecting contact portions 4a, 4a so that the moving contact portion 3f and the detecting contact portions 4a, 4a I support both. As a result, movement of both the moving contact portion 3f and the detection contact portions 4a, 4a can be restricted, so that changes in the amount of elastic deformation of the elastic portion 4c can be restricted.

ところで、特に、弾性部４ｃの弾性変形量が大きくなるように、弾性部４ｃがさらに弾性変形した場合に、移動接点部３ｆと検出接点部４ａ，４ａとが一時的に離れ易くなることを発見することができた。これは、例えば、弾性部４ｃの弾性復元力が一時的に大きくなることが起因していると考えられる。 By the way, it was found that the moving contact portion 3f and the detecting contact portions 4a, 4a are easily separated temporarily when the elastic portion 4c is further elastically deformed so as to increase the elastic deformation amount of the elastic portion 4c. We were able to. It is considered that this is caused, for example, by a temporary increase in the elastic restoring force of the elastic portion 4c.

それに対して、規制部４ｄは、移動接点部３ｆ及び検出接点部４ａ，４ａの両方を下方から支持している。具体的には、移動接点部３ｆと規制部４ｄとは、検出接点部４ａを上下方向Ｄ３で挟んでいる。これにより、移動接点部３ｆと検出接点部４ａとが下方へ移動することを確実に規制することができる。したがって、弾性部４ｃの弾性変形量が大きくなることを規制することができる。 On the other hand, the restricting portion 4d supports both the moving contact portion 3f and the detection contact portions 4a, 4a from below. Specifically, the moving contact portion 3f and the restricting portion 4d sandwich the detection contact portion 4a in the vertical direction D3. As a result, downward movement of the moving contact portion 3f and the detection contact portion 4a can be reliably restricted. Therefore, it is possible to restrict the amount of elastic deformation of the elastic portion 4c from increasing.

このように、弾性部４ｃの弾性変形量が変化することを規制することができるため、乗場扉１ｆが閉状態であるにも関わらず、移動接点部３ｆと検出接点部４ａ，４ａとが一時的に離れることを抑制できる。したがって、扉開閉検出装置２が誤検出することを抑制することができる。 In this way, it is possible to regulate the change in the amount of elastic deformation of the elastic portion 4c. You can restrain yourself from leaving the target. Therefore, erroneous detection by the door opening/closing detection device 2 can be suppressed.

なお、移動体３の回動部３ｂは、鉤部３ｇを備えており、検出体４の本体部４ｂは、鉤部３ｇに引っ掛けられる引掛部４ｉを備えている。そして、図８に示すように、移動体３が待機位置に位置しているときに、鉤部３ｇは、引掛部４ｉに引っ掛けられる。これにより、乗場扉１ｆが開くことを防止できるため、乗場扉１ｆを閉状態で維持することができる。したがって、扉開閉検出装置２は、扉施錠装置としても機能する。 The rotating portion 3b of the moving body 3 has a hook portion 3g, and the body portion 4b of the detection body 4 has a hook portion 4i that is hooked on the hook portion 3g. Then, as shown in FIG. 8, when the moving body 3 is positioned at the standby position, the hook portion 3g is hooked on the hook portion 4i. As a result, the landing door 1f can be prevented from being opened, so that the landing door 1f can be maintained in a closed state. Therefore, the door opening/closing detection device 2 also functions as a door locking device.

また、図５に戻り、一対の検出接点部４ａ，４ａが、横方向Ｄ２に離れていることに対して、規制部４ｄは、上部に、それぞれの検出接点部４ａを支持するために、横方向Ｄ２に離れる一対の支持面４ｊ，４ｊと、一対の支持面４ｊ，４ｊの間に配置される凹部４ｋとを備えている。これにより、規制部４ｄの上部の面積を小さくすることができる。 Returning to FIG. 5, the pair of detection contact portions 4a, 4a are separated in the horizontal direction D2. It has a pair of support surfaces 4j, 4j that are separated in the direction D2, and a recess 4k that is arranged between the pair of support surfaces 4j, 4j. Thereby, the area of the upper portion of the restricting portion 4d can be reduced.

したがって、例えば、規制部４ｄの上部に異物が載ることを抑制することができるため、当該異物に起因して移動接点部３ｆが検出接点部４ａ，４ａと接触不良を起こすことを抑制することができる。なお、支持面４ｊは、例えば、本実施形態のように、水平面に沿う平面状に形成されていてもよく、また、例えば、異物が載ることを抑制するために、湾曲面状、又は、水平面に傾斜する平面状に形成されていてもよい。 Therefore, for example, it is possible to suppress foreign matter from being placed on the upper portion of the restricting portion 4d, thereby suppressing contact failure between the moving contact portion 3f and the detection contact portions 4a, 4a due to the foreign matter. can. For example, the support surface 4j may be formed in a planar shape along a horizontal surface as in the present embodiment, or may be formed in a curved surface shape or a horizontal surface shape in order to prevent foreign substances from being placed on the support surface 4j. It may be formed in a planar shape inclined to

以上より、エレベータ１は、乗場Ｘ１に配置されて開閉する乗場扉１ｆと、前記乗場扉１ｆの開閉状態を検出する扉開閉検出装置２と、を備える。 As described above, the elevator 1 includes the hall door 1f that is arranged in the hall X1 to open and close, and the door open/close detection device 2 that detects the open/closed state of the hall door 1f.

そして、本実施形態に係る扉開閉検出装置２は、乗場扉１ｆの開閉状態を検出する扉開閉検出装置２であって、第１接点部（本実施形態においては、検出接点部）４ａと、前記第１接点部４ａに接続される弾性変形可能な弾性部４ｃと、前記乗場扉１ｆが開状態のときに前記第１接点部４ａから離れ、前記乗場扉１ｆが閉状態のときに前記弾性部４ｃが弾性変形するように前記第１接点部４ａに加圧接触する第２接点部（本実施形態においては、移動接点部）３ｆと、前記第１接点部４ａと前記第２接点部３ｆとが接触する状態で移動することを規制する規制部４ｄと、を備える。 The door opening/closing detection device 2 according to the present embodiment is a door opening/closing detection device 2 that detects the opening/closing state of the landing door 1f, and includes a first contact portion (detection contact portion in the present embodiment) 4a, an elastically deformable elastic portion 4c connected to the first contact portion 4a; A second contact portion (in this embodiment, a moving contact portion) 3f that presses and contacts the first contact portion 4a so that the portion 4c is elastically deformed, and the first contact portion 4a and the second contact portion 3f. and a regulating portion 4d that regulates movement in a state in which the .

斯かる構成によれば、第１接点部４ａと第２接点部３ｆとが接触する状態において、第１接点部４ａと第２接点部３ｆとが移動することを規制される。これにより、第１接点部４ａと第２接点部３ｆとが接触する状態において、弾性部４ｃの弾性変形量が変化することを抑制することができる。 According to such a configuration, movement of the first contact portion 4a and the second contact portion 3f is restricted when the first contact portion 4a and the second contact portion 3f are in contact with each other. Thereby, it is possible to suppress a change in the amount of elastic deformation of the elastic portion 4c when the first contact portion 4a and the second contact portion 3f are in contact with each other.

また、本実施形態に係る扉開閉検出装置２においては、前記規制部４ｄは、前記弾性部４ｃの弾性変形量が大きくなるように前記第１接点部４ａと前記第２接点部３ｆとが接触する状態で移動することを規制する、という構成である。 In addition, in the door opening/closing detection device 2 according to the present embodiment, the regulation portion 4d is configured such that the first contact portion 4a and the second contact portion 3f are brought into contact with each other so that the amount of elastic deformation of the elastic portion 4c is increased. It is a configuration that restricts movement in a state where

斯かる構成によれば、第１接点部４ａと第２接点部３ｆとが接触する状態において、弾性部４ｃの弾性変形量が大きくなった場合に、第１接点部４ａと第２接点部３ｆとが離れ易くなることに対して、弾性部４ｃの弾性変形量が大きくなることを規制することができる。 According to such a configuration, when the amount of elastic deformation of the elastic portion 4c increases while the first contact portion 4a and the second contact portion 3f are in contact with each other, the first contact portion 4a and the second contact portion 3f It is possible to restrict the amount of elastic deformation of the elastic portion 4c from increasing, in contrast to the fact that the elastic portion 4c is likely to separate.

また、本実施形態に係る扉開閉検出装置２においては、前記第１接点部４ａは、前記弾性部４ｃの端部に固定され、前記第２接点部３ｆと前記規制部４ｄとは、前記第１接点部４ａを挟む、という構成である。 Further, in the door opening/closing detection device 2 according to the present embodiment, the first contact portion 4a is fixed to the end portion of the elastic portion 4c, and the second contact portion 3f and the restricting portion 4d are connected to the first contact portion 4a. It is the structure which pinches|interposes 1 contact part 4a.

斯かる構成によれば、第１接点部４ａは、弾性部４ｃの端部に固定されており、第２接点部３ｆと規制部４ｄとは、第１接点部４ａを挟んでいる。これにより、弾性部４ｃの弾性変形量が大きくなることを確実に規制することができる。 According to such a configuration, the first contact portion 4a is fixed to the end portion of the elastic portion 4c, and the first contact portion 4a is sandwiched between the second contact portion 3f and the restricting portion 4d. As a result, it is possible to reliably prevent the amount of elastic deformation of the elastic portion 4c from increasing.

なお、エレベータ１及び扉開閉検出装置２は、上記した実施形態の構成に限定されるものではなく、また、上記した作用効果に限定されるものではない。また、エレベータ１及び扉開閉検出装置２は、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。例えば、下記する各種の変更例に係る構成や方法等を任意に一つ又は複数選択して、上記した実施形態に係る構成や方法等に採用してもよいことは勿論である。 Note that the elevator 1 and the door opening/closing detection device 2 are not limited to the configurations of the above-described embodiments, and are not limited to the above-described effects. Further, the elevator 1 and the door opening/closing detection device 2 can of course be modified in various ways without departing from the scope of the present invention. For example, it is of course possible to arbitrarily select one or a plurality of configurations, methods, etc., according to various modified examples described below and employ them in the configurations, methods, etc., according to the above-described embodiment.

（１）上記実施形態に係る扉開閉検出装置２においては、第１接点部（検出接点部）４ａと第２接点部（移動接点部）３ｆとが接触する状態において、規制部４ｄは、弾性部４ｃの弾性変形量が大きくなることのみを規制する、という構成である。しかしながら、扉開閉検出装置２は、斯かる構成に限られない。 (1) In the door opening/closing detection device 2 according to the above-described embodiment, when the first contact portion (detection contact portion) 4a and the second contact portion (moving contact portion) 3f are in contact with each other, the restricting portion 4d is elastic. It is configured to restrict only an increase in the amount of elastic deformation of the portion 4c. However, the door opening/closing detection device 2 is not limited to such a configuration.

例えば、第１接点部（検出接点部）４ａと第２接点部（移動接点部）３ｆとが接触する状態において、規制部４ｄは、弾性部４ｃの弾性変形量が小さくなることのみを規制する、という構成でもよい。また、例えば、第１接点部（検出接点部）４ａと第２接点部（移動接点部）３ｆとが接触する状態において、規制部４ｄは、弾性部４ｃの弾性変形量が大きくなることも小さくなることも規制する、という構成でもよい。 For example, when the first contact portion (detection contact portion) 4a and the second contact portion (moving contact portion) 3f are in contact with each other, the restricting portion 4d only restricts the amount of elastic deformation of the elastic portion 4c to decrease. , may be used. Further, for example, in a state where the first contact portion (detection contact portion) 4a and the second contact portion (moving contact portion) 3f are in contact with each other, the restricting portion 4d prevents the elastic deformation amount of the elastic portion 4c from increasing. It may also be configured to regulate what happens.

例えば、上記実施形態に係る扉開閉検出装置２に対して、規制部４ｄは、上方から第２接点部（移動接点部）３ｆを止めて支持することによって、弾性部４ｃの弾性変形量が小さくなることを規制する、という構成でもよい。斯かる構成においては、例えば、規制部４ｄは、移動体３が待機位置に位置したときに回動部３ｂを上方から支持する支持位置と、移動体３が移動位置に位置するときに回動部３ｂから離れる待機位置との間を、移動可能である、という構成してもよい。 For example, in the door opening/closing detection device 2 according to the above-described embodiment, the restricting portion 4d stops and supports the second contact portion (moving contact portion) 3f from above, thereby reducing the amount of elastic deformation of the elastic portion 4c. It may also be configured to regulate what happens. In such a configuration, for example, the restricting portion 4d is positioned at a support position where the rotating portion 3b is supported from above when the moving body 3 is positioned at the standby position, and at a rotating portion when the moving body 3 is located at the moving position. It may be configured to be movable between a standby position away from the portion 3b.

（２）また、上記実施形態に係る扉開閉検出装置２においては、規制部４ｄは、第１接点部（検出接点部）４ａを下方から支持する、という構成である。しかしながら、扉開閉検出装置２は、斯かる構成に限られない。例えば、規制部４ｄは、第１接点部４ａを側方から支持する、という構成でもよい。また、例えば、図９及び図１０に示すように、規制部２ａは、第１接点部４ａを上方から支持する、という構成でもよい。 (2) Further, in the door opening/closing detection device 2 according to the above-described embodiment, the restricting portion 4d is configured to support the first contact portion (detection contact portion) 4a from below. However, the door opening/closing detection device 2 is not limited to such a configuration. For example, the restricting portion 4d may be configured to support the first contact portion 4a from the side. Further, for example, as shown in FIGS. 9 and 10, the restricting portion 2a may be configured to support the first contact portion 4a from above.

図９及び図１０に係る戸開閉検出装置２おいては、図９に示すように、移動体３が移動位置に位置しているときに、接点部３ｆ，４ａ同士は、互いに離れている。そして、図１０に示すように、移動体３が待機位置に位置しているときには、接点部３ｆ，４ａ同士は、接触している。 9 and 10, the contact portions 3f and 4a are separated from each other when the moving body 3 is positioned at the moving position, as shown in FIG. Then, as shown in FIG. 10, when the moving body 3 is positioned at the standby position, the contact portions 3f and 4a are in contact with each other.

このとき、移動体３の加力部３ｅが、回動部３ｂに力を加えているため、検出体４の弾性部４ｃは、弾性変形している。これにより、移動接点部３ｆには、加力部３ｅの力により上向きの力が加えられ、検出接点部４ａには、弾性部４ｃの弾性復元力により下向きの力が加えられている。そして、規制部２ａは、第１接点部４ａを上方から支持している。 At this time, since the force applying portion 3e of the moving body 3 applies force to the rotating portion 3b, the elastic portion 4c of the detecting body 4 is elastically deformed. As a result, an upward force is applied to the moving contact portion 3f by the force of the force applying portion 3e, and a downward force is applied to the detection contact portion 4a by the elastic restoring force of the elastic portion 4c. The restricting portion 2a supports the first contact portion 4a from above.

（３）また、上記実施形態に係る扉開閉検出装置２においては、弾性部４ｃに接続される第１接点部４ａは、検出体４に備えられており、第２接点部３ｆは、移動体３に備えられている、という構成である。しかしながら、扉開閉検出装置２は、斯かる構成に限られない。例えば、弾性部に接続される第１接点部は、移動体３に備えられており、第２接点部は、検出体４に備えられている、という構成でもよい。 (3) In addition, in the door opening/closing detection device 2 according to the above embodiment, the first contact portion 4a connected to the elastic portion 4c is provided on the detection body 4, and the second contact portion 3f is provided on the moving body. 3 is provided. However, the door opening/closing detection device 2 is not limited to such a configuration. For example, the moving body 3 may be provided with the first contact portion connected to the elastic portion, and the detection body 4 may be provided with the second contact portion.

（４）また、上記実施形態に係る扉開閉検出装置２においては、弾性部４ｃは、板バネ状に形成されている、という構成である。しかしながら、扉開閉検出装置２は、斯かる構成に限られない。例えば、弾性部４ｃは、弦巻バネ形状に形成されている、という構成でもよい。 (4) Further, in the door opening/closing detection device 2 according to the above-described embodiment, the elastic portion 4c is formed in the shape of a leaf spring. However, the door opening/closing detection device 2 is not limited to such a configuration. For example, the elastic portion 4c may be configured to have a coiled spring shape.

（５）また、上記実施形態に係る扉開閉検出装置２においては、第２接点部（移動接点部）３ｆと規制部４ｄとは、第１接点部（検出接点部）４ａを挟む、という構成である。しかしながら、扉開閉検出装置２は、斯かる構成に限られない。 (5) Further, in the door opening/closing detection device 2 according to the above embodiment, the second contact portion (moving contact portion) 3f and the restricting portion 4d sandwich the first contact portion (detection contact portion) 4a. is. However, the door opening/closing detection device 2 is not limited to such a configuration.

例えば、規制部４ｄは、弾性部４ｃを支持することによって、第１接点部（検出接点部）４ａと第２接点部（移動接点部）３ｆとが接触した状態で移動することを規制している、という構成でもよい。また、例えば、第１接点部（検出接点部）４ａと規制部４ｄとは、第２接点部（移動接点部）３ｆを挟む、という構成でもよい。 For example, by supporting the elastic portion 4c, the restricting portion 4d restricts the movement of the first contact portion (detection contact portion) 4a and the second contact portion (moving contact portion) 3f while they are in contact with each other. The configuration may be such that there is Further, for example, the first contact portion (detection contact portion) 4a and the restriction portion 4d may be configured to sandwich the second contact portion (moving contact portion) 3f.

（６）また、上記実施形態に係る扉開閉検出装置２においては、第１接点部（検出接点部）４ａ，４ａは、一対備えられ、第２接点部（移動接点部）３ｆは、一つ備えらえている、という構成である。しかしながら、扉開閉検出装置２は、斯かる構成に限られない。即ち、第１及び第２接点部４ａ，３ｆの個数は、特に限定されない。例えば、第１及び第２接点部４ａ，３ｆが、それぞれ一つ備えられ、第１接点部４ａと第２接点部３ｆとが接触することによって、扉開閉検出装置２は、乗場扉１ｆが閉状態であると検出する、という構成でもよい。 (6) In addition, in the door opening/closing detection device 2 according to the above embodiment, a pair of the first contact portions (detection contact portions) 4a, 4a are provided, and a single second contact portion (moving contact portion) 3f is provided. It is a configuration that is prepared. However, the door opening/closing detection device 2 is not limited to such a configuration. That is, the numbers of the first and second contact portions 4a and 3f are not particularly limited. For example, each of the first and second contact portions 4a and 3f is provided, and when the first contact portion 4a and the second contact portion 3f come into contact with each other, the door opening/closing detection device 2 detects that the landing door 1f is closed. It may be configured to detect that it is in the state.
