Description

この発明は、エレベータ装置に関し、特に敷居の溝内に異物が挟まれないエレベータ装置に関するものである。   The present invention relates to an elevator apparatus, and more particularly to an elevator apparatus in which foreign matter is not caught in a groove of a sill.

敷居溝内への異物の混入を未然に防止して、異物により戸の開閉ができなくなるのを防止するために、一方の戸の下端部にゴムベルト等からなる閉塞帯の一端部を固定するとともに、この閉塞帯を他方の戸の下端部の滑車に巻き掛けて、戸開時に敷居溝内に閉塞帯を敷設して敷設溝を閉塞するようにし、また、滑車に巻き掛けられた閉塞帯の他端部には、重りを吊り下げて、閉塞帯に張力を与えるとともに、戸閉時に重りの重量により閉塞帯を戸側へ収納するようにすることが提案されている（例えば、特許文献１参照）。   In order to prevent foreign matter from entering the sill groove and prevent the foreign matter from opening and closing the door, one end of a closing belt made of a rubber belt or the like is fixed to the lower end of one door. Wrap this closure band around the pulley at the lower end of the other door so that when the door is open, the closure band is laid in the sill groove to close the laying groove. It has been proposed that a weight is suspended from the other end to apply tension to the closing band, and that the closing band is housed on the door side by the weight of the weight when the door is closed (for example, Patent Document 1). reference).

また、案内溝内の全域に亘って、足部の摺動に応じて圧縮変形と塑性変形を行う弾性を有するスポンジと、スポンジの表面に接着された耐摩耗性を有する補強部材とにより構成された溝塞ぎ手段が設けられていて、足部の位置しない部分で補強部材の上面と敷居部の上面とが同一平面になるように構成されている（例えば、特許文献２参照）。   In addition, it is composed of an elastic sponge that performs compression deformation and plastic deformation according to the sliding of the foot over the entire area in the guide groove, and a wear-resistant reinforcing member that is bonded to the surface of the sponge. The groove closing means is provided, and the upper surface of the reinforcing member and the upper surface of the sill portion are configured to be flush with each other at the portion where the foot portion is not located (see, for example, Patent Document 2).

特開平６−５６３７７号公報JP-A-6-56377 特開平７−６１７５１号公報Japanese Patent Laid-Open No. 7-61751

しかし、特許文献１のように戸の内部に滑車や重りを設けるとともに両方の戸の間に閉塞帯を敷設しなければならず、構造が複雑であるとともに高価であるという問題がある。
また、特許文献２のように案内溝内が耐摩耗性を有する補強部材で表面が覆われたスポンジにより埋められるが、戸の繰り返し開閉による変形によりクリープすることを防止できるスポンジは高価であるとともに、案内溝内がスポンジのような固体で埋められているので戸の移動がスムーズでないという問題がある。 However, as in Patent Document 1, a pulley and a weight must be provided inside the door, and a closing band must be laid between both doors, which causes a problem that the structure is complicated and expensive.
Further, as in Patent Document 2, the inside of the guide groove is filled with a sponge whose surface is covered with a wear-resistant reinforcing member, but a sponge that can be prevented from creeping due to repeated opening and closing of the door is expensive. There is a problem in that the movement of the door is not smooth because the guide groove is filled with a solid such as a sponge.

この発明の目的は、戸の移動を案内する敷居の溝の中に異物が入り込まないよう安価に対処されたエレベータ装置を提供することである。   An object of the present invention is to provide an elevator apparatus that is inexpensively dealt with so that foreign matter does not enter a groove of a sill that guides the movement of a door.

そして、この発明の実施の形態１に係るエレベータ装置は、図１に示すように、エレベータの乗りカゴの戸１が全開位置に位置しているとき敷居２の溝３を塞ぐ溝塞ぎ部材４および開閉する戸１により溝塞ぎ部材４を移動するレバー機構５を備える。 Embodiment 1 FIG.
1 to 3 are front views of a door of a passenger car of the elevator apparatus according to Embodiment 1 of the present invention. 1 is located at the fully open position, the door of FIG. 2 is located at the fully closed position, and the door of FIG. 3 is located when contacting the door stop.
The elevator apparatus according to the first embodiment of the present invention includes an elevator car door 1 and a landing door that are guided to move horizontally to each sill 2 provided with grooves 3. In addition, in the following description, although the content regarding the door 1 of the elevator car is demonstrated, since the content regarding the door of each landing is the same, description is abbreviate | omitted. Moreover, although it demonstrates regarding the door 1 which is a double door, even if it is the door 1 which is a single door, it is applicable similarly.
As shown in FIG. 1, the elevator apparatus according to Embodiment 1 of the present invention includes a groove closing member 4 that closes the groove 3 of the sill 2 when the elevator car door 1 is located at the fully open position, and A lever mechanism 5 for moving the groove closing member 4 by the door 1 that opens and closes is provided.

この発明の実施の形態１に係る溝塞ぎ部材４は、戸１が全開位置に位置するとき開いた乗降口に現れた敷居２の溝３の上面を塞ぎ、且つ戸１が全閉位置に位置するとき敷居２の溝３の底３ａに退避する溝塞ぎ板１１、および、溝塞ぎ板１１の下面から下方に延びるとともに敷居２の溝３の底３ａに設けられた孔３ｂを貫通するガイド棒１２から構成されている。   The groove closing member 4 according to the first embodiment of the present invention closes the upper surface of the groove 3 of the sill 2 that appears at the doorway opened when the door 1 is located at the fully open position, and the door 1 is located at the fully closed position. A groove closing plate 11 that retreats to the bottom 3a of the groove 3 of the sill 2 and a guide bar that extends downward from the lower surface of the groove closing plate 11 and penetrates the hole 3b provided in the bottom 3a of the groove 3 of the sill 2 12 is comprised.

この発明の実施の形態１に係るレバー機構５は、全開位置に位置する戸１の下側に略水平に置かれるレバー１４、レバー１４の一端部に固定される戸当たり具１５、レバー１４と戸当たり具１５とが固定された箇所を回転自在に支持する支持軸１６、レバー１４の他端部に固定されるとともに溝塞ぎ板１１を下側から支持するせり上げ具１７、および、レバー１４が略水平位置から傾くとき戸当たり具１５が当接してレバー１４の傾きを制限するストッパー１８から構成されている。   The lever mechanism 5 according to the first embodiment of the present invention includes a lever 14 that is placed substantially horizontally on the lower side of the door 1 that is located at the fully open position, a door stopper 15 that is fixed to one end of the lever 14, a lever 14, A support shaft 16 that rotatably supports a place where the door stopper 15 is fixed, a lifting tool 17 that is fixed to the other end of the lever 14 and supports the groove closing plate 11 from below, and a lever 14 The door stopper 15 is in contact with the stopper 14 to limit the inclination of the lever 14 when tilted from a substantially horizontal position.

支持軸１６は、全開位置に位置する戸１に対して戸開方向の先方に設けられ、戸当たり具１５は、支持軸１６を中心として戸閉方向に傾いている。
レバー１４は、戸当たり具１５がストッパー１８に当接しているときには支持軸１６を中心としてせり上げ具１７が固定されている他端部が下降する。他方、レバー１４は、全開位置に位置する戸１により戸当たり具１５が戸開方向に立たされたときには支持軸１６を中心としてせり上げ具１７が固定されている他端部が上昇する。
せり上げ具１７は、敷居２の溝３の深さを３０ｍｍとすると約３０ｍｍ上下するので、せり上げ具１７が固定されているレバー１４の他端部を３０ｍｍ上下させなければならない。そこで、レバー１４の長さを１１００ｍｍとすると、レバー１４を支持軸１６を中心として角度１．５６度回転しなければならない。そのため、ストッパー１８に当接している戸当たり具１５は全開位置に移動する手前の戸１により戸開方向に角度１．５６度起こされる。 The support shaft 16 is provided at the front of the door 1 in the door opening direction with respect to the door 1 located at the fully open position, and the door stopper 15 is inclined in the door closing direction about the support shaft 16.
When the door stopper 15 is in contact with the stopper 18, the lever 14 is lowered at the other end where the lifting tool 17 is fixed around the support shaft 16. On the other hand, when the door stopper 15 is stood in the door opening direction by the door 1 located at the fully open position, the lever 14 is lifted at the other end where the lifting tool 17 is fixed around the support shaft 16.
The lifting tool 17 moves up and down by about 30 mm when the depth of the groove 3 of the sill 2 is 30 mm. Therefore, the other end of the lever 14 to which the lifting tool 17 is fixed must be moved up and down by 30 mm. Therefore, if the length of the lever 14 is 1100 mm, the lever 14 must be rotated about the support shaft 16 at an angle of 1.56 degrees. Therefore, the door stop 15 in contact with the stopper 18 is raised 1.56 degrees in the door opening direction by the door 1 on the near side that moves to the fully open position.

溝塞ぎ板１１は、せり上げ具１７が下降位置に位置しているときには自重により敷居２の溝３の底３ａまで下降し、せり上げ具１７が上昇位置に位置しているときにはせり上げ具１７により押し上げられる力が加えられ、敷居２の溝３の上面を塞ぐ位置に保持されている。
ガイド棒１２は、溝塞ぎ板１１がせり上げ具１７により押し上げられるときと溝塞ぎ板１１が自重で降下するとき、孔３ｂに案内されて溝塞ぎ板１１を上下方向だけにガイドする。 The groove closing plate 11 is lowered by its own weight to the bottom 3a of the groove 3 of the sill 2 when the lifting tool 17 is located at the lowered position, and when the lifting tool 17 is located at the raised position. The force pushed up by is applied, and is held at a position for closing the upper surface of the groove 3 of the sill 2.
The guide rod 12 is guided by the hole 3b to guide the groove closing plate 11 only in the vertical direction when the groove closing plate 11 is pushed up by the lifting tool 17 and when the groove closing plate 11 is lowered by its own weight.

次に、戸１が開閉する際の溝塞ぎ部材４およびレバー機構５の動作について説明する。
戸１が全閉位置に位置しているとき、図２に示すように、戸当たり具１５がストッパー１８に当接することにより、レバー１４はせり上げ具１７が固定された他端部が下降してせり上げ具１７が下降位置に停止している。また、溝塞ぎ板１１は自重により敷居２の溝３の底３ａに置かれる。
次に、戸１が戸開移動を開始しても、図３に示すように、戸１が戸当たり具１５に当たるまでは溝塞ぎ板１１は敷居２の溝３の底３ａに置かれている。
戸１が戸当たり具１５に当たり戸当たり具１５を戸開方向に傾きを起こすとレバー１４の他端部が上昇し、他端部に固定されたせり上げ具１７も上昇するので、溝塞ぎ板１１が上昇する。
戸１が全開位置に達すると、図１に示すように、溝塞ぎ板１１が敷居２の溝３の縁まで上昇する。このように、敷居２の溝３の縁と同じ上面で溝３が塞がれているので、乗客が乗り降りしたときに敷居２上に動いた異物は溝３の中に入り込むことが防げる。 Next, the operation of the groove closing member 4 and the lever mechanism 5 when the door 1 is opened and closed will be described.
When the door 1 is located at the fully closed position, as shown in FIG. 2, the door stopper 15 abuts against the stopper 18, whereby the lever 14 is lowered at the other end to which the lifting tool 17 is fixed. The lifting tool 17 is stopped at the lowered position. Further, the groove closing plate 11 is placed on the bottom 3a of the groove 3 of the sill 2 by its own weight.
Next, even if the door 1 starts the door opening movement, as shown in FIG. 3, the groove closing plate 11 is placed on the bottom 3 a of the groove 3 of the sill 2 until the door 1 hits the door stop 15. .
When the door 1 hits the door stop 15 and tilts the door stop 15 in the door opening direction, the other end of the lever 14 rises, and the lifting tool 17 fixed to the other end also rises. 11 rises.
When the door 1 reaches the fully open position, the groove closing plate 11 rises to the edge of the groove 3 of the sill 2 as shown in FIG. As described above, since the groove 3 is closed on the same upper surface as the edge of the groove 3 of the sill 2, it is possible to prevent foreign matters that have moved on the sill 2 from entering the groove 3 when a passenger gets on and off.

この発明の実施の形態１に係るエレベータ装置では、上昇位置に位置するとき敷居２の溝３を塞ぐとともに下降位置に位置するとき戸１が敷居２の溝３内を移動することを妨げないよう溝３の底３ａに置かれる溝塞ぎ板１１と、戸１が全開位置に近づいたとき溝塞ぎ板１１を押し上げるレバー機構５を備えるので、敷居２の溝３に異物が入り込みことを溝塞ぎ板１１とレバー機構５という簡単な部材で安価に防止できる。   In the elevator apparatus according to the first embodiment of the present invention, the groove 1 of the sill 2 is closed when the elevator apparatus is located at the raised position, and the door 1 is not prevented from moving in the groove 3 of the sill 2 when located at the lowered position. Since the groove closing plate 11 placed on the bottom 3a of the groove 3 and the lever mechanism 5 that pushes up the groove closing plate 11 when the door 1 approaches the fully open position, the groove closing plate prevents foreign matter from entering the groove 3 of the sill 2. 11 and the lever mechanism 5 can be prevented at low cost.

The groove closing member 4B according to the second embodiment of the present invention is different in that a return spring 22 that elastically supports the groove closing member 4 according to the first embodiment of the present invention with respect to the sill 2 is added. Since the other parts are the same, the same parts are denoted by the same reference numerals and the description thereof is omitted.

そして、この発明の実施の形態２に係る溝塞ぎ部材４Ｂは、戸１が全開位置に位置するとき開いた乗降口に現れた敷居２の溝３の上面を塞ぎ、且つ戸１が全閉位置に位置するとき敷居２の溝３の底３ａまで下降する溝塞ぎ板１１、溝塞ぎ板１１の下面から下方に延びるとともに敷居２の溝３の底３ａに設けられた孔３ｂを貫通するガイド棒１２、ガイド棒１２の下端面に固定された受板２１、および、敷居２の溝３の底３ａの裏面と受板２１とに両端が当接される戻しばね２２から構成されている。   And the groove closing member 4B which concerns on Embodiment 2 of this invention blocks the upper surface of the groove | channel 3 of the sill 2 which appeared in the entrance which opened when the door 1 was located in a fully open position, and the door 1 was a fully closed position A groove closing plate 11 that descends to the bottom 3a of the groove 3 of the sill 2, and a guide bar that extends downward from the lower surface of the groove closing plate 11 and penetrates the hole 3b provided in the bottom 3a of the groove 3 of the sill 2 12, a receiving plate 21 fixed to the lower end surface of the guide rod 12, and a return spring 22 whose both ends are in contact with the back surface of the bottom 3 a of the groove 3 of the sill 2 and the receiving plate 21.

溝塞ぎ板１１は、せり上げ具１７が下降位置に位置しているときには戻しばね２２の付勢力により敷居２の溝３の底３ａまで下降され、せり上げ具１７が上昇位置に位置しているときにはせり上げ具１７により戻しばね２２の付勢力に抗する力が加えられ、敷居２の溝３の上面を塞ぐ位置に保持されている。   The groove closing plate 11 is lowered to the bottom 3a of the groove 3 of the sill 2 by the urging force of the return spring 22 when the lifting tool 17 is located at the lowered position, and the lifting tool 17 is located at the raised position. A force against the urging force of the return spring 22 is sometimes applied by the lifting tool 17 and is held at a position where the upper surface of the groove 3 of the sill 2 is closed.

次に、戸１が開閉する際の溝塞ぎ部材４Ｂおよびレバー機構５の動作について説明する。
戸１が全閉位置に位置しているとき、図４に示すように、戸当たり具１５がストッパー１８に当接することにより、レバー１４はせり上げ具１７が固定された他端部が下降してせり上げ具１７が下降位置に停止している。また、溝塞ぎ板１１は戻しばね２２により敷居２の溝３の底３ａに押し付けられている。
次に、戸１が戸開移動を開始しても、戸１が戸当たり具１５に当たるまでは溝塞ぎ板１１は戻りばね２２により敷居２の溝３の底３ａに押し付けられている。
戸１が戸当たり具１５に当たり戸当たり具１５を戸開方向に傾きを起こすとレバー１４の他端部が上昇し、他端部に固定されたせり上げ具１７も上昇するので、戻しばね２２の付勢力に抗して溝塞ぎ板１１が上昇する。
戸１が全開位置に達すると、図５に示すように、溝塞ぎ板１１が敷居２の溝３の縁まで上昇するとともに戻しばね２２の付勢力によりその上昇位置に保持される。このように、敷居２の溝３の縁と同じ上面で溝３が塞がれているので、乗客が乗り降りしたときに敷居２上に動いた異物は溝３の中に入り込むことが防げる。 Next, the operation of the groove closing member 4B and the lever mechanism 5 when the door 1 is opened and closed will be described.
