Description
本発明は、エレベータにおいてかごが着床していない状態で乗場の扉が開くのを防ぐためのエレベータの乗場側ロック機構に関する。 The present invention relates to an elevator landing-side locking mechanism for preventing a landing door from being opened when a car is not landing on the elevator.
従来から、エレベータにおいてかごが着床していない状態で乗場の扉が開くのを防ぐための乗場側ロック機構が知られている（特許文献１参照）。この乗場側ロック機構は、図６に示すような、エレベータの乗場の上部に配置され且つ当該乗場の扉（乗場側扉）１０１の開閉に伴って水平方向に移動する掛止部１０２と、前記乗場の上部に固定され且つ掛止部１０２が掛止される被掛止部１０６とを前記エレベータの各階の乗場においてそれぞれ備える。 2. Description of the Related Art A landing-side lock mechanism for preventing a landing door from being opened in a state where a car is not landing in an elevator is known (see Patent Document 1). As shown in FIG. 6, the landing-side locking mechanism is arranged at the upper part of the elevator landing and is moved in the horizontal direction in accordance with the opening and closing of the landing door (landing-side door) 101. A hooked portion 106 fixed to the upper part of the hall and to which the hooking portion 102 is hooked is provided at the hall of each floor of the elevator.
掛止部１０２は、乗場側扉１０１の戸当たり側の先端にフック１０３が形成され且つ乗場側扉１０１に対して回動可能に固定された掛止部本体１０４と、掛止部本体１０４に取り付けられる一対の被挟持部１０５と、を有する。掛止部本体１０４のフック１０３は、乗場側扉１０１が閉じた状態のときに、被掛止部１０６と係合する。一対の被挟持部１０５のうちの一方の被挟持部１０５Ａは、掛止部本体１０４の回動軸１０４Ａと同軸に配置され、他方の被挟持部１０５Ｂは、一方の被挟持部１０５Ａに対して垂直方向よりも戸当たり側にややずれた位置に配置されている。 The hooking portion 102 includes a hooking portion main body 104 that has a hook 103 formed at the front end of the landing-side door 101 and is pivotably fixed to the landing-side door 101, and the hooking portion main body 104. And a pair of sandwiched portions 105 to be attached. The hook 103 of the latching section main body 104 engages with the latched section 106 when the landing-side door 101 is closed. One sandwiched portion 105A of the pair of sandwiched portions 105 is disposed coaxially with the rotation shaft 104A of the latching portion main body 104, and the other sandwiched portion 105B is in relation to the one sandwiched portion 105A. It is arranged at a position slightly shifted from the vertical direction to the door stop side.
このように構成される乗場側ロック機構１００は、前記エレベータのかご１１０がある階に着床していないときは、乗場側扉１０１の開閉と連動する掛止部１０２が、乗場の上部に固定されている被掛止部１０６に掛止されているため、乗場側扉１０１が開くのを防ぐ。 In the landing-side lock mechanism 100 configured as described above, when the elevator car 110 is not landing on the floor, the latching portion 102 that interlocks with the opening and closing of the landing-side door 101 is fixed to the upper part of the landing. Since it is latched by the to-be-latched part 106, the landing side door 101 is prevented from opening.
一方、前記エレベータのかご１１０が所定の階に着床し、該かご１１０の扉（かご側扉）１１１が戸開するときには、該かご１１０に設けられた挟持機構１１２によって一対の被挟持部１０５Ａ、１０５Ｂが開閉方向に挟み込まれることで、他方の被挟持部１０５Ｂが一方の被挟持部１０５Ａ（回動軸１０４Ａ）を回転中心にして回動する。そして、他方の被挟持部１０５Ｂが一方の被挟持部１０５Ａに対して鉛直方向の位置に至るまで回動するのに伴い、掛止部本体１０４は、回動軸１０４Ａを回転中心にしてフック１０３が上方に移動するように回動し、これにより、掛止姿勢（図６参照）から開放姿勢（図７参照）に姿勢が変更される。続いて、挟持機構１１２によって一対の被挟持部１０５が挟持された状態でかご側扉１１１が開くことで、乗場側扉１０１がかご側扉１１１と連動して開く。 On the other hand, when the elevator car 110 is landed on a predetermined floor and the door (car side door) 111 of the car 110 is opened, a pair of sandwiched portions 105A is sandwiched by a sandwiching mechanism 112 provided in the car 110. , 105B is sandwiched in the opening / closing direction, so that the other sandwiched portion 105B rotates about the one sandwiched portion 105A (rotating shaft 104A) as a rotation center. Then, as the other clamped portion 105B rotates to reach the position in the vertical direction with respect to the one clamped portion 105A, the hook portion main body 104 has the hook 103 with the rotation shaft 104A as the rotation center. Is rotated so as to move upward, whereby the posture is changed from the latching posture (see FIG. 6) to the open posture (see FIG. 7). Subsequently, when the car-side door 111 is opened in a state where the pair of sandwiched portions 105 are held by the holding mechanism 112, the landing-side door 101 is opened in conjunction with the car-side door 111.
また、上述の乗場側ロック機構１００では、かご１１０が所定の階に着床したときに、かご１１０の垂直方向の位置が予定されている位置（着床位置）から予め設定されている値（設定値）以上ずれていると、掛止部１０２の一対の被挟持部１０５の位置が、垂直方向において挟持機構１１２が挟み込める範囲（挟持範囲）から外れるため、掛止部本体１０４の姿勢が掛止姿勢のままで維持されてフック１０３と被掛止部１０６との係合状態が保たれる。即ち、乗場側ロック機構１００は、かご１１０が乗場において着床位置から所定量以上ずれているときには、乗場側扉１０１が開くのを防ぐ。これにより、乗場の床とかご１１０の床との間に大きな段差が生じた状態で乗場側扉１０１が開くのを防ぐことができる。 Further, in the above-described landing-side lock mechanism 100, when the car 110 has landed on a predetermined floor, a value set in advance from a position (landing position) where the vertical position of the car 110 is planned (landing position) ( Since the position of the pair of sandwiched portions 105 of the latching portion 102 deviates from the range (nipping range) in which the clamping mechanism 112 can be sandwiched in the vertical direction, the posture of the latching portion main body 104 is The engagement state between the hook 103 and the hooked portion 106 is maintained while maintaining the hooking posture. That is, the landing-side lock mechanism 100 prevents the landing-side door 101 from opening when the car 110 is displaced from the landing position by a predetermined amount or more at the landing. Thereby, it is possible to prevent the landing-side door 101 from being opened in a state in which a large step is generated between the floor of the landing and the floor of the car 110.
ところで、エレベータの設置された建物によっては、複数の階のうちの一部の階（例えば、一階）の乗場側扉１０１の垂直方向の寸法（ドア高さ）が他の階の乗場側扉１０１の垂直方向の寸法よりも大きい場合や、複数の階のうちの一部の階（例えば、一階）の乗場の上部に、かご１１０のいる階等を表示する表示部が配置されている場合がある。これらの場合には、乗場側扉１０１の上端位置の違いや、メンテナンス時に表示部の裏側（昇降路内側）から該表示部へアクセスするためのスペースを確保する等のために、前記一部の階の乗場における掛止部本体１０４の高さ位置（配置位置）が残りの階の乗場における掛止部本体１０４の高さ位置（配置位置）より高い位置に配置されることがある。 By the way, depending on the building where the elevator is installed, the vertical dimension (door height) of the landing-side door 101 of a part of the floors (for example, the first floor) may be a landing-side door of another floor. When the size is larger than the vertical dimension of 101, a display unit that displays the floor where the car 110 is located is arranged at the upper part of the landing on some of the floors (for example, the first floor). There is a case. In these cases, in order to secure the space for accessing the display unit from the back side (inside the hoistway) of the display unit during maintenance, for example, the difference in the upper end position of the landing side door 101, The height position (arrangement position) of the latching part main body 104 at the landing on the floor may be arranged at a position higher than the height position (arrangement position) of the latching part main body 104 at the landing on the remaining floors.
このように、複数の階のうちの一部の階の乗場における掛止部本体１０４の高さ位置が、残りの階の乗場における掛止部本体１０４の高さ位置と異なる場合、挟持機構１１２の挟持範囲を大きくすることにより、この挟持機構１１２によって全ての階の乗場において掛止部１０２の一対の被挟持部１０５を挟み込めるようにすることがある。 Thus, when the height position of the latching part main body 104 at the landing on one of the floors is different from the height position of the latching part main body 104 at the landing on the remaining floors, the holding mechanism 112 By enlarging the pinching range, the pinching mechanism 112 may pinch the pair of pinched portions 105 of the latching portion 102 at the landings of all floors.
しかし、挟持機構１１２の挟持範囲を大きくすると、かご１１０が乗場に着床したときに、かご１１０の着床位置からのずれが前記設定値以上であっても、掛止部１０２の一対の被挟持部１０５が挟持機構１１２に挟み込まれて乗場側扉１０１が開いてしまうときがある。このように、挟持機構１１２の挟持範囲を大きくすると、乗場側ロック機構１００が、乗場の床とかご１１０の床との間に大きな段差が生じたときに乗場側扉１０１が開くことを防げない場合がある。 However, if the clamping range of the clamping mechanism 112 is increased, even when the car 110 is landed on the landing, even if the deviation of the car 110 from the landing position is equal to or more than the set value, There is a case where the pinching portion 105 is pinched by the pinching mechanism 112 and the landing side door 101 is opened. Thus, when the clamping range of the clamping mechanism 112 is increased, the landing-side lock mechanism 100 cannot prevent the landing-side door 101 from opening when a large step is generated between the floor of the landing floor and the floor of the car 110. There is a case.
そこで、本発明は、複数の階のうちの一部の階の乗場における掛止部本体の高さ位置が、残りの階の乗場における掛止部本体の高さ位置と異なっているエレベータにおいて、かごが乗場の着床位置から大きくずれているときに、当該乗場の扉が開くのを防ぐことができるエレベータの乗場側ロック機構を提供することを課題とする。 Therefore, the present invention is an elevator in which the height position of the latching section main body at the landing on some of the floors is different from the height position of the latching section main body at the landing on the remaining floors. It is an object of the present invention to provide an elevator landing-side locking mechanism that can prevent the landing door from being opened when the car is greatly deviated from the landing position of the landing.
本発明に係るエレベータの乗場側ロック機構は、エレベータの乗場の上部に配置されて該乗場の扉の開閉に伴って開閉方向に移動する掛止部であって、開閉方向に間隔をあけて配置され且つ前記エレベータのかごに設けられた挟持機構によって挟み込まれることで開閉方向において互いに接近する方向に相対移動可能な一対の被挟持部、及び、該一対の被挟持部の前記相対移動によって掛止姿勢から開放姿勢に姿勢を変更する掛止部本体、を有する掛止部と、前記乗場の上部に固定され且つ該乗場の扉が閉じた状態のときに前記掛止姿勢の前記掛止部本体と係合する被掛止部と、をエレベータの複数の階の前記乗場のそれぞれにおいて備えるエレベータの乗場側ロック機構である。そして、前記複数の階のうちの一部の階の乗場における前記掛止部本体は、前記複数の階のうちの残りの階の乗場における前記掛止部本体の該乗場の床からの高さ位置である基準位置より高い位置又は低い位置に配置される。また、前記一部の階の乗場における前記掛止部の前記一対の被挟持部は、当該掛止部の掛止部本体に対し、当該掛止部本体と前記基準位置との高さの差に応じて、前記残りの階の乗場の前記掛止部での前記掛止部本体に対する前記一対の被挟持部の高さ位置より下方又は上方に配置される。 The elevator landing-side lock mechanism according to the present invention is a latching portion that is arranged at the upper part of the elevator landing and moves in the opening / closing direction along with the opening / closing of the door of the landing, and is arranged at intervals in the opening / closing direction. And a pair of sandwiched portions that can be moved relative to each other in the opening / closing direction by being sandwiched by a sandwiching mechanism provided in the elevator car, and latched by the relative movement of the pair of sandwiched portions A latching portion body having a latching portion main body that changes the posture from a posture to an open posture; and the latching portion main body that is fixed to the upper part of the landing and is in the latching posture when the landing door is closed The elevator landing-side locking mechanism includes a hooked portion that engages with each of the landings on a plurality of floors of the elevator. And the said latching part main body in the landing of the one part floor of the said several floors is the height from the floor of the said landing of the said latching part main body in the landing of the remaining floors of the said several floors. It is arrange | positioned in the position higher or lower than the reference position which is a position. Further, the pair of sandwiched portions of the latching portion at the landing on the partial floor is different from the latching portion main body of the latching portion in the height difference between the latching portion main body and the reference position. In accordance with the above, it is disposed below or above the height position of the pair of sandwiched portions with respect to the latching portion main body at the latching portion of the remaining floor landing.
かかる構成によれば、複数の階のうちの一部の階の乗場において掛止部本体が基準位置と異なる高さ位置（乗場の床からの高さ位置）に配置されていても、前記複数の階の全ての乗場における一対の被挟持部が同じ高さ位置（乗場の床からの高さ位置）となるため、かごに設けられた挟持機構の挟持範囲を抑えることができ、これにより、乗場においてかごが着床位置から大きくずれた状態で該乗場の扉が開くのを確実に防ぐことができる。 According to such a configuration, even when the latching section main body is arranged at a height position (a height position from the floor of the landing) different from the reference position in the landing on some of the floors, Since the pair of sandwiched parts at all the landings on the floor of the floor are at the same height position (height position from the floor of the landing), the clamping range of the clamping mechanism provided in the car can be suppressed, It is possible to reliably prevent the door of the landing from being opened when the car is largely deviated from the landing position at the landing.
また、前記エレベータの乗場側ロック機構では、前記残りの階の乗場の前記掛止部において、前記一対の被挟持部は、前記掛止部本体に取り付けられ、前記一部の階の乗場の前記掛止部は、前記掛止部本体と当該掛止部本体より下方又は上方に配置された前記一対の被挟持部とを接続し、且つ前記一対の被挟持部の前記相対移動を前記掛止部本体に伝達するリンク機構を有してもよい。 Further, in the elevator landing-side lock mechanism, the pair of sandwiched portions are attached to the hook portion main body in the hooking portion of the remaining floor landing, and the elevator of the partial floor landing The latching portion connects the latching portion main body and the pair of sandwiched portions disposed below or above the latching portion main body, and latches the relative movement of the pair of sandwiched portions. You may have a link mechanism which transmits to a section main part.
かかる構成によれば、モータ等の動力を用いることなくリンク機構といった簡素な構成によって、掛止部本体よりも下方又は上方に配置された一対の被挟持部の相対移動を掛止部本体に伝達することができる。 According to such a configuration, the relative movement of the pair of sandwiched portions disposed below or above the latching portion main body is transmitted to the latching portion main body by a simple configuration such as a link mechanism without using power from a motor or the like. can do.
また、前記エレベータの乗場側ロック機構では、前記掛止部本体は、回動することによって掛止姿勢から開放姿勢に姿勢を変更し、前記一対の被挟持部のうちの一方の被挟持部は、該一方の被挟持部と共に開閉方向に移動する扉に対して所定位置に配置され、他方の被挟持部は、前記一方の被挟持部と開閉方向及び垂直方向に異なる位置に配置され且つ前記一方の被挟持部を回転中心に回動可能であってもよい。 Further, in the elevator landing-side lock mechanism, the latching portion main body changes its posture from a latching posture to an open posture by rotating, and one sandwiched portion of the pair of sandwiched portions is , Disposed at a predetermined position with respect to the door moving in the opening / closing direction together with the one sandwiched portion, and the other sandwiched portion is disposed at a position different from the one sandwiched portion in the opening / closing direction and the vertical direction, and One clamped portion may be rotatable about the center of rotation.
かかる構成によれば、掛止部本体、一対の被挟持部、及びリンク機構といった簡素な構成によって、一対の被挟持部を扉の開閉方向に挟み込むことで掛止部本体を回動させる（即ち、掛止姿勢から開放姿勢に姿勢を変更させる）ことができる。 According to such a configuration, with a simple configuration such as the latching portion main body, the pair of sandwiched portions, and the link mechanism, the latching portion main body is rotated by sandwiching the pair of sandwiched portions in the door opening / closing direction (that is, The posture can be changed from the hanging posture to the open posture).
以上より、本発明によれば、複数の階のうちの一部の階の乗場における掛止部本体の高さ位置が、残りの階の乗場における掛止部本体の高さ位置と異なっているエレベータにおいて、かごが乗場の着床位置から大きくずれているときに、当該乗場の扉が開くのを防ぐことができるエレベータの乗場側掛止装置を提供することができる。 As mentioned above, according to this invention, the height position of the latching | locking part main body in the landing of the one part floor of several floors differs from the height position of the latching | holding part main body in the landing of the remaining floors. In the elevator, when the car is largely deviated from the landing position of the landing, it is possible to provide an elevator landing-side hooking device that can prevent the landing door from opening.
以下、本発明の一実施形態について、図１〜図５を参照しつつ説明する。 Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
本実施形態に係るエレベータの乗場側ロック機構（以下、単に「ロック機構」とも称する。）は、エレベータのかご側扉の開閉に用いられるモータ等の動力を伝達させることでかご側扉の開閉に乗場側扉を連動させる扉連動機構に含まれる。具体的には、以下の通りである。 The elevator landing-side lock mechanism (hereinafter also simply referred to as “lock mechanism”) according to the present embodiment opens and closes the car-side door by transmitting power from a motor or the like used to open and close the car-side door of the elevator. It is included in the door interlocking mechanism that interlocks the landing side door. Specifically, it is as follows.
扉連動機構は、図１〜図３に示すように、エレベータの乗場１０に設けられる乗場側係合装置１と、エレベータのかご２０に設けられるかご側係合装置２と、を含む。これら乗場側係合装置１と、かご側係合装置２と、が係合することによって、かご側扉２１を開閉する動力が乗場側扉１１、１１Ａ（図４参照）に伝達され、これにより、かご側扉２１の開閉に追従して乗場側扉１１、１１Ａが開閉する。 As shown in FIGS. 1 to 3, the door interlocking mechanism includes a landing-side engaging device 1 provided in the elevator landing 10 and a car-side engaging device 2 provided in the elevator car 20. When the landing-side engagement device 1 and the car-side engagement device 2 are engaged, the power for opening and closing the car-side door 21 is transmitted to the landing-side doors 11 and 11A (see FIG. 4). Following the opening and closing of the car side door 21, the landing side doors 11 and 11A open and close.
かご側係合装置２は、かご側扉２１の上部に設けられて戸開のときに乗場側係合装置１の一部を挟み込む挟持機構２２を含む。この挟持機構２２は、かご２０の移動方向（本実施形態の例では垂直方向）に延び且つかご側扉２１の開閉方向（以下、単に「開閉方向」と称する。）に間隔をあけて配置される一対の挟持部２３を有する。本実施形態のエレベータは、両開き式の扉であり、挟持機構２２は、一方のかご側扉（図１における右側の扉）２１に設けられる。 The car-side engagement device 2 includes a pinching mechanism 22 that is provided at an upper portion of the car-side door 21 and sandwiches a part of the landing-side engagement device 1 when the door is opened. This clamping mechanism 22 extends in the moving direction of the car 20 (vertical direction in the example of the present embodiment) and is arranged with an interval in the opening / closing direction of the car-side door 21 (hereinafter simply referred to as “opening / closing direction”). A pair of clamping parts 23. The elevator of the present embodiment is a double-open door, and the clamping mechanism 22 is provided on one of the car side doors (the right door in FIG. 1) 21.
尚、本実施形態のエレベータでは、挟持機構２２（一対の挟持部２３）によって乗場側係合装置１の一部（本実施形態の例では、後述する一対の被挟持部５１）を挟み込まなければ、乗場側扉１１、１１Ａが戸開できない。このため、一対の挟持部２３の垂直方向の長さ寸法、即ち、一対の挟持部２３が挟持できる範囲（挟持範囲）によって、かご２０が着床位置からずれたときに乗場側扉１１、１１Ａが戸開しなくなる着床位置からのずれの範囲が規定される。 In the elevator according to the present embodiment, a part of the landing-side engagement device 1 (a pair of sandwiched portions 51 described later in the example of the present embodiment) is not sandwiched by the sandwiching mechanism 22 (the pair of sandwiching portions 23). The landing side doors 11 and 11A cannot be opened. Therefore, the landing-side doors 11 and 11A when the car 20 deviates from the landing position due to the vertical dimension of the pair of sandwiching portions 23, that is, the range in which the pair of sandwiching portions 23 can be sandwiched (the sandwiching range). The range of deviation from the landing position where the door does not open is defined.
一対の挟持部２３のうちの一方の挟持部（固定側挟持部）２３１は、かご側扉２１に固定され、他方の挟持部（可動側挟持部）２３２は、リンク機構等によって固定側挟持部２３１との平行を維持しつつ該固定側挟持部２３１との間隔が狭まるように移動可能である。本実施形態の挟持機構２２では、固定側挟持部２３１が戸当たり側に配置され、可動側挟持部２３２が戸袋側に配置される。そして、かご側扉２１が戸開するときに、固定側挟持部２３１がかご側扉２１と共に戸開方向に移動すると共に、可動側挟持部２３２が固定側挟持部２３１に接近する。これにより、乗場側係合装置１の一部（詳しくは、一対の被挟持部５１）が一対の挟持部２３（固定側挟持部２３１及び可動側挟持部２３２）に挟み込まれる。 One clamping part (fixed side clamping part) 231 of the pair of clamping parts 23 is fixed to the car side door 21, and the other clamping part (movable side clamping part) 232 is a fixed side clamping part by a link mechanism or the like. It is possible to move so that the distance from the fixed-side holding portion 231 is narrowed while maintaining parallel to the H.231. In the clamping mechanism 22 of this embodiment, the fixed side clamping part 231 is arrange | positioned at the door stop side, and the movable side clamping part 232 is arrange | positioned at the door pocket side. When the car-side door 21 is opened, the fixed-side holding part 231 moves in the door-opening direction together with the car-side door 21, and the movable-side holding part 232 approaches the fixed-side holding part 231. Thereby, a part of the landing-side engagement device 1 (specifically, the pair of sandwiched portions 51) is sandwiched between the pair of sandwiching portions 23 (the fixed-side sandwiching portion 231 and the movable-side sandwiching portion 232).
乗場側係合装置１は、かご２０が乗場１０に着床していない状態、詳しくは、かご２０が着床位置から所定量（一対の挟持部２３の垂直方向の長さ（挟持範囲）によって決められる値）以上ずれた状態では、かご側扉２１が戸開しようとしても乗場側扉１１、１１Ａが戸開できないように該乗場側扉１１、１１Ａをロックするロック機構３を有する。即ち、ロック機構３は、かごが乗場１０に着床した状態でかご側扉２１が戸開するときに、乗場側扉１１のロックを解除する。 The landing-side engagement device 1 is in a state where the car 20 is not landing on the landing 10, more specifically, the car 20 is determined from the landing position by a predetermined amount (the vertical length (clamping range) of the pair of clamping portions 23). When the car side door 21 is about to be opened, the landing side doors 11 and 11A are locked so that the landing side doors 11 and 11A cannot be opened. That is, the lock mechanism 3 unlocks the landing-side door 11 when the car-side door 21 opens with the car landing on the landing 10.
このロック機構３は、乗場１０の上部に固定される被掛止部４と、被掛止部４と係合可能な掛止部５とを、エレベータの複数の階（本実施形態の例では全ての階）の乗場１０のそれぞれに備える。 The lock mechanism 3 includes a hooked portion 4 fixed to an upper portion of the hall 10 and a hooked portion 5 that can be engaged with the hooked portion 4, in a plurality of floors of the elevator (in the example of the present embodiment). Prepare for each of the halls 10 on all floors.
被掛止部４は、乗場側扉１１、１１Ａの上端近傍から上方に向かって延びる掛止片４１を有し、乗場１０の開口部上端の壁等に固定されるヘッダーフレーム４２に固定されている。 The hooked portion 4 has a hooking piece 41 extending upward from the vicinity of the upper end of the landing side door 11, 11 </ b> A, and is fixed to a header frame 42 fixed to a wall or the like at the upper end of the opening of the landing 10. Yes.
ヘッダーフレーム４２は、開閉方向に延び且つ乗場側扉１１、１１Ａの上端に取り付けられたドアハンガー１２を開閉方向に案内するレール４３を有する。即ち、乗場側扉１１、１１Ａは、ドアハンガー１２に吊り下げられた状態でレール４３に沿って移動（開閉）する。 The header frame 42 has a rail 43 that extends in the opening and closing direction and guides the door hanger 12 attached to the upper ends of the landing side doors 11 and 11A in the opening and closing direction.

When the car 20 reaches the landing 10, the pair of sandwiched portions 51 of the landing 10 is positioned between the pair of sandwiching portions 23 that move up and down together with the car 20. Subsequently, when the car-side door 21 is opened by the power of a motor or the like provided in the car 20, the fixed-side holding part 231 fixed to the car-side door 21 pushes the second held part 512 toward the door pocket. At the same time, the movable side clamping part 232 moves to the fixed side clamping part 231 side so as to sandwich the pair of clamped parts 51. As a result, the pair of sandwiched portions 51 are sandwiched by the sandwiching mechanism 22 (specifically, the pair of sandwiching portions 23), and the latch portion main body 52 is released from the latching posture (see FIGS. 1 and 4) (see FIG. 2). And the posture is changed to FIG. As a result, the hook 525 at the tip of the arm portion 522 is detached from the hooked portion 4 (the hooking piece 41), and the landing-side doors 11 and 11A are unlocked. And if the fixed side clamping part 231 moves to the door pocket side with the door opening of the car side door 21, a pair of to-be-clamped part 51 will be pushed, and, thereby, the landing side doors 11 and 11A will open.
尚、第一の掛止部５Ａでは、一対の被挟持部５１と掛止部本体５２との垂直方向の位置（乗場１０の床からの高さ位置）が異なっているが、リンク機構５５によって一対の被挟持部５１の挙動が掛止部本体５２に伝達される。このため、図１、図２、図４、及び図５に示されるように、第一の掛止部５Ａと第二の掛止部５Ｂとにおいて、一対の被挟持部５１がかご２０の挟持機構２２によって挟み込まれたときの掛止部本体５２の挙動は、同じである。 In the first hooking portion 5A, the vertical positions (the height position from the floor of the landing 10) of the pair of sandwiched portions 51 and the hooking portion main body 52 are different. The behavior of the pair of sandwiched portions 51 is transmitted to the latch portion main body 52. Therefore, as shown in FIGS. 1, 2, 4, and 5, the pair of sandwiched portions 51 sandwich the car 20 in the first latching portion 5 </ b> A and the second latching portion 5 </ b> B. The behavior of the hook body 52 when sandwiched by the mechanism 22 is the same.
また、かご２０が乗場１０に着床せずに当該乗場１０を通過する場合は、一対の挟持部２３が、一対の被挟持部５１の両側（開閉方向における外側）を通過する。 In addition, when the car 20 passes through the landing 10 without landing on the landing 10, the pair of sandwiching portions 23 pass through both sides (outside in the opening and closing direction) of the pair of sandwiched portions 51.
以上のエレベータのロック機構３によれば、複数の階のうちの一部の階（本実施形態の例では一階）の乗場１０において掛止部本体５２が基準位置と異なる高さ位置（乗場１０の床からの高さ位置）に配置されていても、複数の階の全ての乗場１０における一対の被挟持部５１が同じ高さ位置（乗場１０の床からの高さ位置）となる。このため、かご２０に設けられた挟持機構２２の挟持範囲を抑え、これにより、乗場１０においてかご２０が着床位置から大きくずれた状態で乗場側扉１１、１１Ａが開くのを確実に防ぐことができる。 According to the elevator lock mechanism 3 described above, the height of the latching section main body 52 is different from the reference position in the hall 10 on a part of the floors (the first floor in the example of the present embodiment). Even if it is arrange | positioned in the height position from 10 floors), a pair of to-be-clamped part 51 in all the halls 10 of a some floor becomes the same height position (height position from the floor of hall 10). For this reason, the clamping range of the clamping mechanism 22 provided in the car 20 is suppressed, thereby reliably preventing the landing-side doors 11 and 11A from opening in the state where the car 20 is largely deviated from the landing position. Can do.
また、本実施形態のロック機構３の第一の掛止部５Ａでは、モータ等の動力を用いることなくリンク機構５５といった簡素な構成によって、掛止部本体５２より下方に配置された一対の被挟持部５１の相対移動を当該掛止部本体５２に伝達することができる。 Further, the first latching portion 5A of the lock mechanism 3 of the present embodiment has a simple configuration such as a link mechanism 55 without using power of a motor or the like, and a pair of hooks disposed below the latching portion main body 52. The relative movement of the holding part 51 can be transmitted to the latching part main body 52.
また、前記エレベータのロック機構３では、掛止部本体５２、一対の被挟持部５１、及びリンク機構５５といった簡素な構成によって、一対の被挟持部５１を開閉方向に挟み込むことで掛止部本体５２を回動させる（即ち、掛止姿勢から開放姿勢に姿勢を変更させる）ことができる。 Further, the elevator lock mechanism 3 has a simple configuration such as the latching portion main body 52, the pair of sandwiched portions 51, and the link mechanism 55, so that the pair of sandwiched portions 51 is sandwiched in the opening and closing direction. 52 can be rotated (that is, the posture can be changed from the latching posture to the open posture).
尚、本発明のエレベータのロック機構は、上記実施形態に限定されるものではなく、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、ある実施形態の構成に他の実施形態の構成を追加することができ、また、ある実施形態の構成の一部を他の実施形態の構成に置き換えることができる。さらに、ある実施形態の構成の一部を削除することができる。 It should be noted that the elevator locking mechanism of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention. For example, the configuration of another embodiment can be added to the configuration of a certain embodiment, and a part of the configuration of a certain embodiment can be replaced with the configuration of another embodiment. Furthermore, a part of the configuration of an embodiment can be deleted.
上記実施形態のエレベータでは、該エレベータの設けられた建物の全ての階に乗場１０が設けられているが、この構成に限定されず、複数の階に乗場が設けられていればよい。 In the elevator of the above embodiment, the halls 10 are provided on all the floors of the building where the elevators are provided. However, the elevators are not limited to this configuration, and the halls may be provided on a plurality of floors.
掛止部５における一対の被挟持部５１の動き（相対移動）を掛止部本体５２に伝達する具体的構成は、限定されない。例えば、上記実施形態のロック機構３では、一対の被挟持部５１の動きをリンク機構５５によって掛止部本体５２に伝達しているが、一対の被挟持部５１の動きを掛止部本体５２に伝達できれば、他の構成であってもよい。 A specific configuration for transmitting the movement (relative movement) of the pair of sandwiched portions 51 in the latching portion 5 to the latching portion main body 52 is not limited. For example, in the lock mechanism 3 of the above embodiment, the movement of the pair of sandwiched portions 51 is transmitted to the latching portion main body 52 by the link mechanism 55, but the movement of the pair of sandwiched portions 51 is transmitted. Other configurations may be used as long as they can be transmitted.
上記実施形態のエレベータでは、掛止部本体５２の高さ位置が基準位置と異なる乗場（一部の階の乗場）１０が一つであるが、複数であってもよい。また、一部の階の乗場（掛止部本体５２の高さ位置が基準位置と異なる乗場）１０が複数の場合、前記複数の乗場に配置された掛止部本体のそれぞれの高さ位置は、同じであってもよく、異なっていてもよい。 In the elevator according to the above-described embodiment, the number of landings 10 (the landings of some floors) in which the height position of the latching section main body 52 is different from the reference position is one, but there may be a plurality. In addition, when there are a plurality of landings 10 on some floors (the landings where the heights of the latching body 52 are different from the reference positions), the respective height positions of the latching bodies disposed on the plurality of landings are , May be the same or different.
また、上記実施形態のロック機構３では、第一の掛止部（一部の階の乗場１０における掛止部）５Ａの一対の被挟持部５１は、掛止部本体５２より下方に配置されているが、この構成に限定されない。乗場側扉の垂直方向の寸法が小さい場合等、乗場１０において掛止部本体５２が基準位置より低い位置に配置されている場合には、一対の被挟持部５１は、掛止部本体５２より上方に配置されていてもよい。かかる構成によれば、掛止部本体５２が配置された全ての階の乗場において、一対の被挟持部５１の床からの高さ位置を同じにすることができる。 In the lock mechanism 3 of the above-described embodiment, the pair of sandwiched portions 51 of the first latching portion (the latching portion in the landing 10 on some floors) 5 </ b> A is disposed below the latching portion main body 52. However, it is not limited to this configuration. When the latching part main body 52 is arranged at a position lower than the reference position at the landing 10 such as when the vertical dimension of the landing-side door is small, the pair of sandwiched parts 51 is more than the latching part main body 52. You may arrange | position upwards. According to this structure, the height position from the floor of a pair of to-be-clamped part 51 can be made the same in the landing of all the floors in which the latching part main body 52 is arrange | positioned.
