Description

この発明は、エレベータの乗り場シルとかごシル（敷居）の間の間隙を狭めるために補助シルを取り付けたエレベータのシル構造に関する。   The present invention relates to an elevator sill structure in which an auxiliary sill is attached to narrow a gap between an elevator sill and a car sill (sill).

エレベータの昇降路内で乗りかごが円滑に昇降するために、乗りかごの敷居と乗り場の敷居の間には間隙がある。しかし、この間隙が大きいと、乗りかごに出入する乗客がつまづいたり、車椅子や乳母車の車輪が溝に落ちてスムーズに乗降できない、あるいは乗客が乗降する際に間隙に物を落とす、などの問題がある。この問題を解決するために、乗りかごの敷居と乗り場の敷居の一方または両方に補助シルを取り付ける技術が知られている（特許文献１）。これは、乗りかごの敷居または乗り場の敷居の先端に、敷居の延びる方向に平行に延びて、対向する敷居に向かって突出する補助シルをネジ止めするものである。   In order for the car to move up and down smoothly in the elevator hoistway, there is a gap between the car threshold and the landing threshold. However, if this gap is large, passengers getting in and out of the car get stuck, wheelchairs and baby carriage wheels fall into the groove and can not get on and off smoothly, or passengers drop things into the gap when getting on and off There is. In order to solve this problem, a technique is known in which an auxiliary sill is attached to one or both of a car threshold and a landing threshold (Patent Document 1). In this case, an auxiliary sill that extends parallel to the direction in which the sill extends and protrudes toward the opposing sill is screwed to the tip of the sill of the car or the landing sill.

以下に、図面を参照して本発明の実施形態について説明する。ここで、互いに同一または類似の部分には共通の符号を付して重複説明は省略する。   Embodiments of the present invention will be described below with reference to the drawings. Here, the same or similar parts are denoted by common reference numerals, and redundant description is omitted.

［第１の実施形態］
図１は本発明に係るエレベータのシル構造の第１の実施形態における補助シル付近を示す部分側断面図である。 [First Embodiment]
FIG. 1 is a partial side sectional view showing the vicinity of an auxiliary sill in a first embodiment of an elevator sill structure according to the present invention.

符号１０はたとえば乗りかごのシルであって、かごドア（図示せず）の下方に沿って、間口方向に水平に、シル１０が延びている。このシル１０の乗り場側（図１の左側）先端に補助シル１１が取り付けられている。この補助シル１１は、乗り場側との間隙を調整するために取り付けられるものであって、シル１０の先端に沿って、図１の紙面に垂直な方向に細長く延びている。   Reference numeral 10 is a sill of a car, for example, and the sill 10 extends horizontally in the frontage direction along the lower side of the car door (not shown). An auxiliary sill 11 is attached to the front end of the sill 10 on the landing side (left side in FIG. 1). The auxiliary sill 11 is attached to adjust the gap with the landing side, and extends along the tip of the sill 10 in a direction perpendicular to the paper surface of FIG.

シル１０が補助シル１１に対向する面には補助シル１１を取り付けるための取り付け溝１２が、補助シル１１の延びる方向に延びるように形成されている。この取り付け溝１２の開口部近くは幅狭部１３となっており、この幅狭部１３の奥（図の右側）に幅広部１４が形成され、さらにその奥に奥細溝１５が形成されている。   An attachment groove 12 for attaching the auxiliary sill 11 is formed on the surface of the sill 10 facing the auxiliary sill 11 so as to extend in the direction in which the auxiliary sill 11 extends. Near the opening of the mounting groove 12 is a narrow portion 13, a wide portion 14 is formed at the back (right side of the figure) of the narrow portion 13, and a deep narrow groove 15 is formed at the back. Yes.

補助シル１１には、乗り場側から補助シル１１に向かって水平に延びる貫通孔１６が形成されている。貫通孔１６はたとえば丸穴であって、複数個が、補助シル１１の長手方向に互いに間隔をあけて配置されている。   The auxiliary sill 11 has a through hole 16 extending horizontally from the landing side toward the auxiliary sill 11. The through holes 16 are, for example, round holes, and a plurality of the through holes 16 are arranged in the longitudinal direction of the auxiliary sill 11 with a space therebetween.

貫通孔１６にはボルト１７の軸部１８が貫通している。軸部１８は、取り付け溝１２の幅狭部１３、幅広部１４を貫通し、軸部１８の先端は奥細溝１５の途中まで延びている。軸部１８の先端近くはネジ部１９になっていてネジ部１９にナット２０が螺合している。ナット２０は取り付け溝１２の幅広部１４に配置されている。ボルト１７の頭部２１は、補助シル１１の乗り場に対向する面側に位置し、補助シル１１の乗り場に対向する面と頭部２１との間にバネ座金２２が挟み込まれている。   The shaft portion 18 of the bolt 17 passes through the through hole 16. The shaft portion 18 passes through the narrow portion 13 and the wide portion 14 of the attachment groove 12, and the tip of the shaft portion 18 extends partway through the deep narrow groove 15. Near the tip of the shaft portion 18 is a screw portion 19, and a nut 20 is screwed into the screw portion 19. The nut 20 is disposed in the wide portion 14 of the mounting groove 12. The head portion 21 of the bolt 17 is located on the side of the auxiliary sill 11 facing the landing, and a spring washer 22 is sandwiched between the surface of the auxiliary sill 11 facing the landing and the head 21.

ナット２０は幅狭部１３を通り抜けられない形状・寸法であって、ボルト１７のネジ部１９とナット２０とを締め付けることにより、補助シル１１とシル１０の幅狭部１３を囲む部分とが互いに押し付けられて、補助シル１１とシル１０とが結合される。また、バネ座金２２を挟み込むことによってネジの緩みを防止することができる。   The nut 20 has a shape and size that cannot pass through the narrow portion 13, and by tightening the screw portion 19 of the bolt 17 and the nut 20, the portion surrounding the auxiliary sill 11 and the narrow portion 13 of the sill 10 is mutually connected. The auxiliary sill 11 and the sill 10 are joined by pressing. Further, the screw can be prevented from loosening by sandwiching the spring washer 22.

補助シル１１の乗り場に対向する面の上部には、乗り場に向かって水平に突出する上部突出部２３が形成され、ボルト１７の頭部２１の先端は上部突出部２３よりも乗り場側に突出しない寸法になっている。   An upper protrusion 23 that protrudes horizontally toward the landing is formed on the upper surface of the auxiliary sill 11 facing the landing, and the tip of the head 21 of the bolt 17 does not protrude further toward the landing than the upper protrusion 23. It is a dimension.

補助シル１１をシル１０に取り付け、またはこれを取り外すときに、ボルト１７とナット２０とを締め付けていない状態では、ナット２０は取り付け溝１２の幅広部１４内で、その溝方向に平行移動可能である。しかも、ナット２０は、幅広部１４内でボルト２０のネジ部１９の周りで１回転以上の回転ができない寸法形状である。たとえば、ナット２０の軸に垂直な断面が正六角形の場合、取り付け溝１２の幅広部１４の溝幅がナット２０の反対側２面の間隔よりもわずかに大きい程度にしておけば、ナット２０が幅広部１４内で軸回りに回転できる角度は６０未満になる。   When the auxiliary sill 11 is attached to or removed from the sill 10, the nut 20 can be translated in the direction of the groove within the wide portion 14 of the attachment groove 12 when the bolt 17 and the nut 20 are not tightened. is there. Moreover, the nut 20 has a dimensional shape that cannot be rotated more than one turn around the threaded portion 19 of the bolt 20 in the wide portion 14. For example, when the cross section perpendicular to the axis of the nut 20 is a regular hexagon, if the groove width of the wide portion 14 of the mounting groove 12 is slightly larger than the interval between the two opposite surfaces of the nut 20, the nut 20 The angle that can rotate around the axis in the wide portion 14 is less than 60.

このような構成とすることにより、ナット２０を取り付け溝１２に沿って平行に移動し、ボルト１７の位置に適宜合わせることができ、しかも、ボルト１７の頭部２１をスパナなどによって回転させたときにナット２０の回転を防ぐことができる。これにより、補助シル１１をシル１０に取り付けるさいの作業性がよくなる。   By adopting such a configuration, the nut 20 can be moved in parallel along the mounting groove 12 and can be appropriately adjusted to the position of the bolt 17, and the head 21 of the bolt 17 is rotated by a spanner or the like. In addition, the rotation of the nut 20 can be prevented. Thereby, workability when attaching the auxiliary sill 11 to the sill 10 is improved.

さらに、ボルト１７とナット２０が螺合していない状態で、ナット２０だけを取り付けて溝１２の幅広部１４に挿入したときに、ナット２０が幅広部１４内で倒れない形状寸法になっている。すなわち、図１で、ナット２０を幅広部１４内に残したままボルト１７を外したとき、ナット２０は、幅広部１４内の隙間により図１の面内で若干回転して傾斜しうるが、幅広部１４内の隙間が小さいため、ナット２０が横倒しになることはない。そのため、補助シル１１をシル１０に取り付けるさいに、あらかじめ取り付け溝１２の幅広部１４内にナット２０を入れて溝方向に移動させても、ナット２０の姿勢が維持され、貫通孔１６にボルト１７の軸部１８を通したときに、ボルト１７のネジ部１９をナット２０のネジ穴に容易に入れることができる。   Further, when the bolt 17 and the nut 20 are not screwed together, when the nut 20 is attached and inserted into the wide portion 14 of the groove 12, the nut 20 does not fall within the wide portion 14. . That is, in FIG. 1, when the bolt 17 is removed while leaving the nut 20 in the wide portion 14, the nut 20 may be slightly rotated and inclined in the plane of FIG. 1 due to the gap in the wide portion 14. Since the gap in the wide portion 14 is small, the nut 20 does not fall sideways. Therefore, even when the auxiliary sill 11 is attached to the sill 10, even if the nut 20 is inserted into the wide portion 14 of the mounting groove 12 and moved in the groove direction in advance, the posture of the nut 20 is maintained, and the bolt 17 When the shaft portion 18 is passed, the screw portion 19 of the bolt 17 can be easily put into the screw hole of the nut 20.

上記構成の補助シル１１をシル１０に取り付けるに当たっては、あらかじめ取り付け溝１２の幅広部１４内に複数のナット２０を、取り付け溝１２の長手方向端部（図１の紙面の奥側または手前側）から挿入して、ナット２０を溝方向に移動させて、補助シル１１の貫通孔１６に対向する位置に配置し、その後に、シル１０の先端部に補助シル１１を配置し、各貫通孔１６の入口にバネ座金２２を配置した上でボルト１７の軸部１８をバネ座金２２および貫通孔１６に通してナット２０と係合させ、締め付けることができる。   In attaching the auxiliary sill 11 having the above configuration to the sill 10, a plurality of nuts 20 are placed in advance in the wide portion 14 of the attachment groove 12, and the longitudinal end of the attachment groove 12 (the back side or the near side of the paper surface of FIG. 1). Then, the nut 20 is moved in the groove direction and disposed at a position facing the through hole 16 of the auxiliary sill 11, and thereafter, the auxiliary sill 11 is disposed at the tip of the sill 10. After the spring washer 22 is disposed at the inlet, the shaft portion 18 of the bolt 17 can be passed through the spring washer 22 and the through hole 16 to be engaged with the nut 20 and tightened.

また、他の手順として、はじめに、シル１０から離れた位置にある補助シル１１の各貫通孔１６にバネ座金２２を配置した上でボルト１７の軸部１８をバネ座金２２および貫通孔１６に通してナット２０と係合させ、その後に、ナット２０が取り付け溝１２の幅広部１４の端部から幅広部１４内に入るように、ボルト１７、ナット２０およびバネ座金２２が取り付けられた状態の補助シル１１をシル１０に対して相対的に長手方向に移動させていくこともできる。   As another procedure, first, the spring washer 22 is disposed in each through hole 16 of the auxiliary sill 11 located away from the sill 10, and then the shaft portion 18 of the bolt 17 is passed through the spring washer 22 and the through hole 16. The bolt 17, the nut 20, and the spring washer 22 are attached so that the nut 20 enters the wide portion 14 from the end of the wide portion 14 of the mounting groove 12. It is also possible to move the sill 11 in the longitudinal direction relative to the sill 10.

以上説明したように、第１の実施形態によれば、補助シル１１をシル１０取り付けるに当たり、長穴加工や、据付現場でのタップ加工が不要であり、作業性がよくなる。   As described above, according to the first embodiment, when attaching the auxiliary sill 11 to the sill 10, long hole processing and tapping at the installation site are not required, and workability is improved.

［第２の実施形態］
図２は本発明に係るエレベータのシル構造の第２の実施形態における補助シル付近を示す部分側断面図である。この実施形態では、シル１０に形成された取り付け溝１２内にボルト１７の頭部２１が配置され、ナット２０とバネ座金２２が補助シル１１の貫通孔１６の先端側に配置されている。ボルト１７の頭部２１は、取り付け溝１２の幅広部１４内で溝方向に移動可能に配置されている。ボルト１７の頭部２１は、取り付け溝１２の幅狭部１３は通り抜けることができず、しかも、幅広部１４内で軸周りに１回転以上の回転ができない寸法形状である。 [Second Embodiment]
FIG. 2 is a partial side sectional view showing the vicinity of an auxiliary sill in a second embodiment of the elevator sill structure according to the present invention. In this embodiment, the head 21 of the bolt 17 is disposed in the mounting groove 12 formed in the sill 10, and the nut 20 and the spring washer 22 are disposed on the distal end side of the through hole 16 of the auxiliary sill 11. The head portion 21 of the bolt 17 is disposed so as to be movable in the groove direction within the wide portion 14 of the mounting groove 12. The head portion 21 of the bolt 17 cannot be passed through the narrow portion 13 of the mounting groove 12 and has a dimension and shape that cannot rotate more than one rotation around the axis within the wide portion 14.

この実施形態では、第１の実施形態と違ってボルト１７の軸部１８先端が取り付け溝１２内にないので、奥細溝１５（図１）は不要である。   In this embodiment, unlike the first embodiment, the tip end of the shaft portion 18 of the bolt 17 is not in the mounting groove 12, so that the deep narrow groove 15 (FIG. 1) is unnecessary.

また、ボルト１７の軸部１８先端が補助シル１１の上部突出部２３よりも乗り場側に突出しない寸法になっている。   Further, the tip of the shaft portion 18 of the bolt 17 is dimensioned so as not to protrude to the landing side with respect to the upper protruding portion 23 of the auxiliary sill 11.

この実施形態によれば、第１の実施形態とほぼ同様の効果を得ることができる。なお、この実施形態では、幅広部１４内にボルト１７の頭部２１があり、頭部２１は軸部１８と一体であるから、第１の実施形態のようにナット２０が幅広部１４内で倒れてボルトの軸部１８先端と係合できなくなるのを防ぐために幅広部１４が大きすぎないように配慮する必要はない。   According to this embodiment, substantially the same effect as that of the first embodiment can be obtained. In this embodiment, there is a head portion 21 of the bolt 17 in the wide portion 14, and the head portion 21 is integral with the shaft portion 18, so that the nut 20 is in the wide portion 14 as in the first embodiment. There is no need to consider that the wide portion 14 is not too large in order to prevent it from falling and being unable to engage with the tip of the shaft portion 18 of the bolt.

［第３の実施形態］
図３は本発明に係るエレベータのシル構造の第３の実施形態における補助シル付近を示す部分側断面図である。この実施形態は第１の実施形態の変形であって、補助シル１１に、シル１０の取り付け溝１２内に向かって突出するシル側突起部３０が形成されている。シル側突起部３０は取り付け溝１２に沿って水平に延びていて、取り付け溝１２の幅狭部１３と嵌合している。その他の構成は第１の実施形態と同様である。 [Third Embodiment]
FIG. 3 is a partial sectional side view showing the vicinity of the auxiliary sill in the third embodiment of the elevator sill structure according to the present invention. This embodiment is a modification of the first embodiment, and the auxiliary sill 11 is formed with a sill-side protrusion 30 that protrudes into the mounting groove 12 of the sill 10. The sill-side protrusion 30 extends horizontally along the attachment groove 12 and is fitted to the narrow portion 13 of the attachment groove 12. Other configurations are the same as those of the first embodiment.

この実施形態によれば、第１の実施形態と同様の効果が得られるとともに、補助シル１１のシル側突起部３０がシル１０の取り付け溝１２の幅狭部１３と嵌合していることから、この嵌合部を通して、補助シル１１にかかる荷重の一部をシル１０に伝えることができる。第１の実施形態では、補助シル１１にかかる荷重は、ボルト１７の軸部１８にかかるせん断力と、補助シル１１とシル１０が鉛直接触面３１（図１）に生じる摩擦力を通じてシル１０に伝達される。それに対してこの実施形態では、補助シル１１のシル側突起部３０とシル１０の取り付け溝１２の幅狭部１３との間の嵌合部で、補助シル１１にかかる荷重の一部をシル１０に伝達させることができる。そのため、第１の実施形態よりも構造強度を高めることができる。また、同程度の構造強度を維持しながら、補助シル１１取り付け用のボルト１７とナット２０の組数を少なくすることもできる。   According to this embodiment, the same effects as those of the first embodiment can be obtained, and the sill-side protrusion 30 of the auxiliary sill 11 is fitted with the narrow portion 13 of the mounting groove 12 of the sill 10. A part of the load applied to the auxiliary sill 11 can be transmitted to the sill 10 through this fitting portion. In the first embodiment, the load applied to the auxiliary sill 11 is applied to the sill 10 through the shearing force applied to the shaft portion 18 of the bolt 17 and the frictional force generated between the auxiliary sill 11 and the sill 10 on the vertical contact surface 31 (FIG. 1).
