まず、本発明の第１の実施例におけるエレベーター出入口装置について、図１〜図７を用いて説明する。図１及び図２は、いずれも、間口方向の所定の場所における敷居６と係合体３の位置関係を示す断面図である。そのうち、図１は、出入口が閉じ状態のときなど、所定の場所における敷居６の上方にドア１が存在している場合を示している。一方、図２は、出入口が開き状態のときなど、所定の場所における敷居６の上方にドア１が存在していない場合を示している。   First, the elevator doorway apparatus in the 1st Example of this invention is demonstrated using FIGS. 1 and 2 are cross-sectional views showing the positional relationship between the threshold 6 and the engagement body 3 at a predetermined place in the frontage direction. Among them, FIG. 1 shows a case where the door 1 exists above the sill 6 at a predetermined location, such as when the doorway is closed. On the other hand, FIG. 2 shows a case where the door 1 does not exist above the sill 6 at a predetermined location, such as when the doorway is open.

図１に示す通り、本実施例の出入口装置は、乗降床やかご床などの床面８の端部に設けられた敷居６と、この敷居６に形成された上方へ開口する凹部である敷居溝７と、この敷居溝７内に設けられた閉塞手段としての係合体３と、この係合体３の一部を支えながら間口方向へ移動するドア１を具備している。   As shown in FIG. 1, the entrance / exit device of this embodiment includes a sill 6 provided at an end of a floor surface 8 such as a passenger floor or a car floor, and a sill groove that is a recess formed in the sill 6 and opens upward. 7, an engagement body 3 as a closing means provided in the sill groove 7, and a door 1 that moves in the frontage direction while supporting a part of the engagement body 3.

ここで、ドア１の底面には、ドア溝が設けられており、このドア溝の内側面には、互いに対向する係合用凸部２が形成されている。一方で、係合体３の側部には、ドア１の係合用凸部２に引っ掛かりながら案内される係合用凹部４が形成されている。また、係合体３の底部には塵埃逃がし溝５が設けられ、係合体３の上面部には平坦化手段が取り付けられている。   Here, a door groove is provided on the bottom surface of the door 1, and engaging protrusions 2 that face each other are formed on the inner surface of the door groove. On the other hand, on the side of the engagement body 3, an engagement recess 4 is formed that is guided while being caught by the engagement protrusion 2 of the door 1. Further, a dust escape groove 5 is provided at the bottom of the engagement body 3, and a flattening means is attached to the upper surface of the engagement body 3.

尚、ドア溝の係合用凸部２は、ドア１の間口方向の一端から他端まで連続して設けずに、図３の如く、ドア１の一部の箇所に設けても良い。また、この係合用凸部２の両端の上側を曲面状にする等して、係合体３をスムーズに乗り上げさせ、係合体３の係合用凹部４との接触による振動や騒音の低減を図ることもできる。   The door groove engaging convex portion 2 may be provided at a part of the door 1 as shown in FIG. Further, the engaging body 3 can be smoothly run by making the upper side of both ends of the engaging convex portion 2 curved, and vibration and noise due to contact of the engaging body 3 with the engaging concave portion 4 are reduced. You can also.

更に、本実施例の係合体３は、図４に示すように多数の係合部材１１を連結して構成され、蛇状の構造となっている。そして、この連続的な係合体３の全体としての寸法は、図６に示す通り、敷居溝７のすべてを覆うまでの長さは必要ないが、少なくとも出入口幅の長さ以上としている。また、図６のような２枚ドア両開きの出入口装置の場合、ドア１に引きずられて係合体３が間口方向へずれないように、ドア１の閉じ端の位置Ａにおいて、敷居６と係合体３とを固定するのが良い。尚、本実施例では、図５に示す通り、ピン９を用いて多数の係合部材１１を連結して係合体３を構成しているが、係合体３の材料として、例えば、テフロン（登録商標）等、軽くて自己潤滑性があり、かつ、摩擦係数が小さい高分子材料を使用すれば、一体物として構成することも可能である。   Furthermore, the engaging body 3 of the present embodiment is configured by connecting a large number of engaging members 11 as shown in FIG. 4 and has a snake-like structure. And as the whole dimension of this continuous engagement body 3, as shown in FIG. 6, the length until it covers all the sill grooves 7 is not necessary, but it is more than the length of the entrance / exit width. Further, in the case of the two-door double door opening / closing device as shown in FIG. 3 should be fixed. In this embodiment, as shown in FIG. 5, the engagement body 3 is configured by connecting a large number of engagement members 11 using pins 9, but the material of the engagement body 3 is, for example, Teflon (registered) If a polymer material such as a trademark, which is light and self-lubricating, and has a low friction coefficient, it can be configured as a single body.

次に、本実施例の出入口装置の動作について説明する。まず、出入口が開き状態のときは、出入口幅内の所定位置における敷居６の上方には、ドア１が存在しないため、その所定位置における係合体３は、敷居溝７内に完全に収納されている。このとき、平坦化手段を含む係合体３の上面が、出入口の床面８の高さに位置しているため、ドア１が開いているときに露出する敷居溝７を塞ぐことが可能となる。その結果、異物の入り込みに起因するドア１の動作障害や、傘又はハイヒールなどの引っ掛かりに起因する乗客の転倒を抑制できる。   Next, operation | movement of the entrance / exit apparatus of a present Example is demonstrated. First, when the doorway is in an open state, the door 1 does not exist above the sill 6 at a predetermined position within the doorway width, so that the engaging body 3 at the predetermined position is completely stored in the sill groove 7. Yes. At this time, since the upper surface of the engagement body 3 including the flattening means is located at the height of the floor surface 8 of the entrance / exit, it becomes possible to close the sill groove 7 exposed when the door 1 is opened. . As a result, it is possible to suppress the operation failure of the door 1 due to the entry of foreign objects and the fall of the passenger due to the catch of an umbrella or high heel.

そして、ドア１が移動して出入口が閉じ状態へ移行する際には、図５のように、ドア１の係合用凸部２が接近するにつれて、この係合用凸部２に近い側の係合部材１１が次第に持ち上げられる。その後、係合部材１１の係合用凹部４がドア１の係合用凸部２にまで達すると、図１のような状態となる。このとき、上方にドア１が存在する場所における係合体３は、その上面の少なくとも一部が、出入口の床面８よりも高く位置することになる。したがって、乗客がドア１にもたれかかったり、ドアを押したりしても、ドア１が外れるのを防止できる。   Then, when the door 1 moves and the entrance / exit shifts to the closed state, as shown in FIG. 5, as the engaging convex portion 2 of the door 1 approaches, the engagement closer to the engaging convex portion 2 is engaged. The member 11 is gradually lifted. Thereafter, when the engagement concave portion 4 of the engagement member 11 reaches the engagement convex portion 2 of the door 1, the state shown in FIG. 1 is obtained. At this time, at least a part of the upper surface of the engaging body 3 in the place where the door 1 is present is positioned higher than the floor surface 8 of the doorway. Therefore, even if the passenger leans against the door 1 or pushes the door, the door 1 can be prevented from coming off.

このように、本実施例における係合体３は、ドア１が開いているときの敷居溝７を塞ぐ機能と、ドア１の外れを防止する機能を兼ねた役割を果たすことになる。しかも、この係合体３を設けるに際して、敷居６の側方に出張ることがないので、乗場側敷居とかご側敷居との間の隙間を広げなくて済む。尚、ドア１の通過に伴って上下する上述の係合体３は、乗場側の敷居溝７と、かご側の敷居溝７のどちらか一方に設けても有効であるが、図７のように、両方の敷居に設けても勿論良い。   Thus, the engagement body 3 in the present embodiment plays a role of both a function of closing the sill groove 7 when the door 1 is open and a function of preventing the door 1 from coming off. Moreover, when this engaging body 3 is provided, there is no business trip to the side of the sill 6, so that it is not necessary to widen the gap between the landing side sill and the car side sill. The above-described engaging body 3 that moves up and down with the passage of the door 1 is effective even if it is provided in either the landing-side sill groove 7 or the car-side sill groove 7, as shown in FIG. Of course, it may be provided on both thresholds.

図８及び図９は、本発明の第２の実施例におけるエレベーター出入口装置の構成を示した図である。これら図８及び図９の通り、本実施例では、ドア溝の内側面に、第１の実施例と違い、係合ローラ１２が設けられている。つまり、第１の実施例における係合用凸部２が、ガイドシュー方式であるのに対して、本実施例における係合ローラ１２は、ガイドローラ方式となっている。   8 and 9 are diagrams showing the configuration of the elevator doorway apparatus in the second embodiment of the present invention. As shown in FIGS. 8 and 9, in this embodiment, the engagement roller 12 is provided on the inner surface of the door groove, unlike the first embodiment. That is, the engaging convex portion 2 in the first embodiment is a guide shoe system, whereas the engaging roller 12 in the present embodiment is a guide roller system.

また、本実施例の係合体３も、第１の実施例と同様に、敷居溝７を塞いで異物が入り難くすると共に、ドア１の移動に追従してその上部がドア１と係合するように案内されている。更に、第１の実施例と同様に、乗場床８ａからかご床８ｂに至るまで平坦な状態が多くなり、乗客がエレベーターに乗降する際の安全性を高めることが可能となる。   Further, the engaging body 3 of this embodiment also closes the sill groove 7 to make it difficult for foreign matter to enter, and the upper portion of the engaging body 3 engages with the door 1 following the movement of the door 1 as in the first embodiment. Have been guided. Further, as in the first embodiment, the flat state increases from the landing floor 8a to the car floor 8b, and it is possible to improve safety when passengers get on and off the elevator.

尚、第１の実施例では、図６のように２枚ドア両開きの出入口装置の例を説明したが、図１０のように２枚ドア片開きの出入口装置としても構わない。その場合、ドア１の閉じ端Ｂにおいて、敷居６と係合体３を固定することにより、係合体３の間口方向へのずれを防止するのが良い。   In the first embodiment, an example of a two-door double door opening / closing apparatus as shown in FIG. 6 has been described, but a two-door single door opening / closing apparatus as shown in FIG. 10 may be used. In that case, it is preferable to prevent the engagement body 3 from shifting toward the front edge by fixing the threshold 6 and the engagement body 3 at the closed end B of the door 1.

また、上述の第１及び第２の実施例では、係合体３に係合用凹部４を設けると共に、ドア溝に係合用凸部２を設けているが、係合体３に係合用凸部を設けると共に、ドア溝に係合用凹部を設ける構成も考えられる。   Further, in the first and second embodiments described above, the engaging recess 3 is provided in the engaging body 3 and the engaging convex portion 2 is provided in the door groove. However, the engaging convex portion is provided in the engaging body 3. A configuration in which an engagement recess is provided in the door groove is also conceivable.
