FIG. 5 is a configuration diagram showing another shape of the upper frame and the edge plate according to the embodiment of the present invention.

まず、図１、図２を用いて三方枠の構成について説明する。   First, the configuration of the three-way frame will be described with reference to FIGS.

図１に示すように、建物の各階に設けられる乗場１には左右に対向するように配置される横枠２と、この横枠２の上部をつなぐように設けられる上枠３とから構成される三方枠４が設置されている。この三方枠４を構成する横枠２の上端部と上枠３の左右両端部のそれぞれとは図示しないボルト等で連結され固定されており、三方枠４は略門型となっている。   As shown in FIG. 1, a landing 1 provided on each floor of a building is composed of a horizontal frame 2 disposed so as to be opposed to the left and right, and an upper frame 3 provided so as to connect the upper part of the horizontal frame 2. The three-way frame 4 is installed. The upper end portion of the horizontal frame 2 and the left and right end portions of the upper frame 3 constituting the three-way frame 4 are connected and fixed by bolts or the like (not shown), and the three-way frame 4 has a substantially gate shape.

また、乗場１側から見て三方枠４によって形成される昇降路開口部を塞ぐようにして乗場ドア１００が設置されている。図１における乗場ドア１００は左側に戸開する２Ｓドアである。   Further, a landing door 100 is installed so as to block the hoistway opening formed by the three-sided frame 4 when viewed from the landing 1 side. The landing door 100 in FIG. 1 is a 2S door that opens to the left.

図２に示すように、本実施形態における三方枠の上枠３は乗場側に突出する部分が断面コの字型に折り曲げられるようにして各階乗場に設けられている。具体的には、上枠３の下面３ａの乗場１側部分が垂直上方向に折り曲げられて形成される突出面３ｂと、突出面３ｂに対して垂直にかご側方向に折り曲げられて形成される上面３ｃとから断面コの字型の折り曲げ部Ａが形成されている。上面３ｃには後述する縁板を取り付けるための取付穴５が設けられている。取付穴５が設けられる箇所についての詳細は図３を用いて説明する。   As shown in FIG. 2, the upper frame 3 of the three-way frame in the present embodiment is provided at each floor landing such that a portion protruding to the landing side is bent into a U-shaped cross section. Specifically, the landing surface 1 side portion of the lower surface 3a of the upper frame 3 is formed by being bent vertically upward, and is formed by being bent in the car side direction perpendicular to the protruding surface 3b. A U-shaped bent portion A is formed from the upper surface 3c. The upper surface 3c is provided with an attachment hole 5 for attaching an edge plate described later. The details of the location where the mounting hole 5 is provided will be described with reference to FIG.

この折り曲げ部Ａは、図３に示すように、上面３ｃが突出面３ｂと建物壁との距離ｄ１よりも大きい距離Ｄだけ折り曲げて形成される。なお、図３において、実線部分が乗場１側に突出している部分（距離ｄ１）であり、点線部分が建物壁内に埋め込まれる部分（距離ｄ２）である。 The bent portion A, as shown in FIG. 3, the upper surface 3c is formed by bending distance greater D than the distance d 1 between the protruding surface 3b and the building wall. In FIG. 3, the solid line portion is a portion protruding to the landing 1 side (distance d 1 ), and the dotted line portion is a portion embedded in the building wall (distance d 2 ).

また既述の通り、図２、３に示すように、上面３ｃの長手方向、つまり戸開閉方向両端部付近には縁板を取り付けるための取付穴５が設けられている。取付穴５が設けられる場所について、本実施形態においては上面３ｃの戸開閉方向端部から所定距離だけ離れた箇所であって、かつ、建物壁内に設置される範囲に設けられるものとする。ここでいう、建物壁内の範囲とは、前述の距離Ｄと距離ｄ１との差分の部分（距離ｄ２）を指す。すなわち、このような箇所に取付穴５を設けることにより、取付穴５が乗場側に露出することがなくなり、乗場の利用者から見えることがなく意匠的に好ましいものとなる。 As described above, as shown in FIGS. 2 and 3, mounting holes 5 for mounting the edge plates are provided in the longitudinal direction of the upper surface 3 c, that is, in the vicinity of both ends in the door opening / closing direction. In the present embodiment, the mounting hole 5 is provided at a location that is a predetermined distance away from the door opening / closing direction end of the upper surface 3c and that is provided in a range where it is installed in the building wall. Here, the range in the building wall, refers to the portion (distance d 2) of the difference between the distance D and the distance d 1 above. That is, by providing the attachment holes 5 in such places, the attachment holes 5 are not exposed to the landing side, and are not visible to the user of the landing, which is preferable in terms of design.

次に、図４を用いて縁板６の構成について説明する。   Next, the configuration of the edge plate 6 will be described with reference to FIG.

図４に示すように、本実施形態における縁板６（塞ぎ部材）は上枠３の戸開閉方向両端部を外側から塞ぐように取り付けられるものである。縁板６は、上枠３の折り曲げ部Ａによって形成される断面コの字型の空間部分を塞ぐ、塞ぎ面６ａと、塞ぎ面６ａの端部から塞ぎ面６ａに対して略垂直方向に伸びる面である取付面６ｂとからなる。すなわち、縁板６の水平方向からみた投影面は略Ｌ字型となる。   As shown in FIG. 4, the edge plate 6 (blocking member) in the present embodiment is attached so as to close both ends of the upper frame 3 in the door opening / closing direction. The edge plate 6 closes the U-shaped space portion formed by the bent portion A of the upper frame 3, and extends in a direction substantially perpendicular to the closing surface 6 a from the closing surface 6 a and the end of the closing surface 6 a. The mounting surface 6b is a surface. That is, the projection plane viewed from the horizontal direction of the edge plate 6 is substantially L-shaped.

また、この取付面６ｂには、前述の上面３ｃに設けられる取付穴５と対応する位置に取付穴７が設けられている。すなわち、上面３ｃと取付面６ｂとが取付穴５、７に挿入されるボルトやリベット等の締結部材８によって締結されることにより、上枠３と縁板６とが固定され、塞ぎ面６ａが折り曲げ部Ａによって形成される断面コの字型の空間部分Ｂを塞ぐことになる。   The mounting surface 6b is provided with a mounting hole 7 at a position corresponding to the mounting hole 5 provided in the upper surface 3c. That is, the upper surface 3c and the mounting surface 6b are fastened by the fastening members 8 such as bolts and rivets inserted into the mounting holes 5 and 7, whereby the upper frame 3 and the edge plate 6 are fixed, and the closing surface 6a is fixed. The space portion B having a U-shaped cross section formed by the bent portion A is closed.

さらに、本実施形態においては、縁板６の形状として上枠３に取り付けた際の意匠面も考慮した構成となっている。縁板６は塞ぎ面６ａと取付面６ｂとの関係がＣ−Ｃ断面でみるとＬ字形状（Ｘ−Ｚ軸方向）となるように形成されるものであるが、本実施形態においては、取付面６ｂは、塞ぎ面６ａの端部の一部から略垂直方向（Ｘ軸方向）に伸びるものとする。詳細には、取付面６ｂは塞ぎ面６ａの上端部のうちかご側の一部から伸びるものであり、このかご側の一部とは、三方枠４が乗場１に設置されたときに、建物壁内に埋め込まれる部分を指す。すなわち、塞ぎ面６ａと取付面６ｂとの接続部分は、図３に示す距離ｄ２の範囲内に収まる形状となる。 Furthermore, in this embodiment, it is the structure which also considered the design surface at the time of attaching to the upper frame 3 as a shape of the edge board 6. FIG. The edge plate 6 is formed so that the relationship between the closing surface 6a and the mounting surface 6b is L-shaped (XZ axial direction) when viewed in the CC cross section, but in this embodiment, The attachment surface 6b extends in a substantially vertical direction (X-axis direction) from a part of the end of the closing surface 6a. Specifically, the mounting surface 6b extends from a part of the car side of the upper end portion of the closing surface 6a, and this part of the car side means that when the three-sided frame 4 is installed on the landing 1, the building The part embedded in the wall. That is, the connection portion between the closing surface 6a and the mounting surface 6b has a shape that fits within a distance d 2 shown in FIG.

このように、本実施形態における取付面６ｂは建物壁に埋め込まれる範囲で塞ぎ面６ａの上端部から伸びている。これにより、本来板状部材の折り曲げにより発生する折り曲げ角の丸み（いわゆる、Ｒ）が生じる縁板６の部分が建物壁内に埋め込まれる範囲に抑えられる。すなわち、乗場１側から突出している上枠３の露出部分の戸開閉方向両端部における空間部分の塞ぎ面が縁板６と面一に形成され、いわゆるＲが露出部分に見られない三方枠４となる。   Thus, the attachment surface 6b in the present embodiment extends from the upper end portion of the closing surface 6a within a range embedded in the building wall. Thereby, the part of the edge board 6 in which the roundness of the bending angle (so-called R), which is originally generated by bending the plate-like member, is suppressed to a range embedded in the building wall. That is, the three-sided frame 4 in which the closed surface of the space part at both ends of the door opening / closing direction of the exposed part of the upper frame 3 protruding from the landing 1 side is flush with the edge plate 6 and so-called R is not seen in the exposed part. It becomes.

以上のように、本実施形態における三方枠４の上枠３および縁板６を用いることにより、乗場１側から露出して見える上枠３の戸開閉方向両端部の塞ぎ面３ａにいわゆるＲが形成されず、隙間なく塞ぎ面６ａが折り曲げ部Ａによって形成される断面コの字型の空間部分Ｂを塞ぐことができる。   As described above, by using the upper frame 3 and the edge plate 6 of the three-way frame 4 according to the present embodiment, so-called R is formed on the closing surfaces 3a at both ends in the door opening / closing direction of the upper frame 3 that is exposed from the landing 1 side. The space portion B having a U-shaped cross section formed by the bent portion A can be closed without being formed, and the closing surface 6a is formed without any gap.

また、本実施形態における縁板６の形状として、上枠３に対する位置決め機能を有する構成でも良い。具体的には、図５に示すように縁板６の塞ぎ面６ａの下側端部の一部に凸部９を設け、上枠３の戸開閉方向端部にはこの凸部９と対応する位置に凹部１０を設ける。これにより、上枠３に縁板６を取り付ける際に、取付位置が固定され、取付穴５、７の位置決めを容易に行うことができる。   Moreover, the structure which has the positioning function with respect to the upper frame 3 may be sufficient as the shape of the edge board 6 in this embodiment. Specifically, as shown in FIG. 5, a convex portion 9 is provided at a part of the lower end portion of the closing surface 6 a of the edge plate 6, and the convex portion 9 corresponds to the door opening / closing direction end portion of the upper frame 3. The concave portion 10 is provided at a position where the operation is performed. Thereby, when attaching the edge plate 6 to the upper frame 3, an attachment position is fixed and the attachment holes 5 and 7 can be positioned easily.

また、本実施形態における縁板６の形状として、塞ぎ面６ａと取付面６ｂとからなる折り曲げ角の角度は９０度以下であることが望ましい。これは、折り曲げ角の角度が９０度以上である場合には、取付穴５、７を締結部材（８）で締結し上枠３の上面３ｃと縁板６の取付面６ｂとを固定した際に、上枠３の戸開閉方向両端部に対して塞ぎ面６ａが浮き上がってしまう。つまり折り曲げ角の角度が９０度以上である場合は、折り曲げ部Ａによって形成される断面コの字型の空間部分を十分に塞ぐことができず、かつ乗場１側から三方枠４を見た場合、上枠３の両端部から縁板６の塞ぎ面６ａが突出して見えてしまうことになり、意匠的に好ましくない結果となる。さらに、折り曲げ角の角度が９０度以上の場合、前述した縁板６の位置決め機能の有効性が低い結果となりうる。   In addition, as the shape of the edge plate 6 in the present embodiment, it is desirable that the bending angle formed by the closing surface 6a and the mounting surface 6b is 90 degrees or less. This is because when the bending angle is 90 degrees or more, the mounting holes 5 and 7 are fastened by the fastening member (8) and the upper surface 3c of the upper frame 3 and the mounting surface 6b of the edge plate 6 are fixed. In addition, the closing surface 6a is lifted from both ends of the upper frame 3 in the door opening / closing direction. In other words, when the angle of the bending angle is 90 degrees or more, the space portion having a U-shaped cross section formed by the bent portion A cannot be sufficiently blocked and the three-side frame 4 is viewed from the landing 1 side. Then, the closing surface 6a of the edge plate 6 protrudes from both end portions of the upper frame 3, which is not desirable in design. Further, when the angle of the bending angle is 90 degrees or more, the effectiveness of the positioning function of the edge plate 6 described above may be low.

これに対し、折り曲げ角の角度が９０度以下であって、前述した縁板６の位置決め機能を有している場合には、取付穴５、７を締結部材８で締結し上枠３の上面３ｃと縁板６の取付面６ｂとを固定した際、塞ぎ面６ａの凸部９が上枠３の凹部１０に対して荷重がかかるため、より、塞ぎ面６ａによる塞ぎが確実なものとなる。   On the other hand, when the bending angle is 90 degrees or less and the edge plate 6 has the positioning function described above, the mounting holes 5 and 7 are fastened by the fastening member 8 and the upper surface of the upper frame 3 is fastened. When the 3c and the mounting surface 6b of the edge plate 6 are fixed, the convex portion 9 of the blocking surface 6a applies a load to the concave portion 10 of the upper frame 3, so that the blocking by the blocking surface 6a becomes more reliable. .

以上のことを考慮し、縁板６の塞ぎ面６ａと取付面６ｂとからなる折り曲げ角の角度は８５度以上９０度以下となるものがより好ましい。   Considering the above, it is more preferable that the angle of the folding angle formed by the closing surface 6a and the mounting surface 6b of the edge plate 6 is 85 degrees or more and 90 degrees or less.
