　ドア１は、ドアハンガー２と、一対のドアパネル３と、敷居４と、を備える。ドアハンガー２は、ドア１の上部に設けられる。ドアハンガー２は、ドア１の開閉方向に延びる。一対のドアパネル３の各々は、板状の機器である。一対のドアパネル３の各々の厚さ方向は、ｘ軸の方向に向けられる。一対のドア１の各々は、ドアシュー５を備える。ドアシュー５は、ドアパネル３の下端部に設けられる。一対のドアパネル３の各々の上端部は、ドアハンガー２に掛けられる。一対のドアパネル３の荷重は、ドアハンガー２に支持されている。一対のドアパネル３の各々は、ドア１が開閉するときに、ドアハンガー２に沿って移動する。このとき、一対のドアパネル３は、互いに反対方向に移動する。敷居４は、ドア１の下部に設けられる。敷居４は、ドア１の開閉方向に延びる。敷居４は、敷居溝６を有する。敷居溝６は、ドア１の開閉方向に長い溝である。敷居溝６は、上方から挿し込まれているドアシュー５をドア１が開閉するときに案内する溝である。 The door 1 includes a door hanger 2, a pair of door panels 3, and a threshold 4. The door hanger 2 is provided on the upper part of the door 1. The door hanger 2 extends in the opening / closing direction of the door 1. Each of the pair of door panels 3 is a plate-shaped device. The thickness direction of each of the pair of door panels 3 is oriented in the x-axis direction. Each of the pair of doors 1 includes a door shoe 5. The door shoe 5 is provided at the lower end of the door panel 3. The upper ends of each of the pair of door panels 3 are hung on the door hanger 2. The load of the pair of door panels 3 is supported by the door hanger 2. Each of the pair of door panels 3 moves along the door hanger 2 when the door 1 opens and closes. At this time, the pair of door panels 3 move in opposite directions. The threshold 4 is provided below the door 1. The threshold 4 extends in the opening / closing direction of the door 1. The sill 4 has a sill groove 6. The threshold groove 6 is a groove long in the opening / closing direction of the door 1. The sill groove 6 is a groove that guides the door shoe 5 inserted from above when the door 1 opens and closes.
　図２は、実施の形態１に係るドアシューの図１におけるＡ－Ａ断面図である。 FIG. 2 is a sectional view taken along the line AA in FIG. 1 of the door shoe according to the first embodiment.
　敷居４は、側壁７を敷居溝６に有する。側壁７は、ドア１の開閉方向に長い壁面である。敷居４は、敷居溝６の底面に図示されない穴が設けられていてもよい。敷居溝６に入り込んだ異物は、例えば底面の穴から排出される。 The sill 4 has a side wall 7 in the sill groove 6. The side wall 7 is a wall surface that is long in the opening / closing direction of the door 1. The sill 4 may be provided with a hole (not shown) on the bottom surface of the sill groove 6. Foreign matter that has entered the threshold groove 6 is discharged from, for example, a hole on the bottom surface.
　ドアシュー５は、取付部８と、摺動部９と、を備える。 The door shoe 5 includes a mounting portion 8 and a sliding portion 9.
　取付部８は、ドアパネル３の下端部に設けられる部分である。取付部８は、例えばネジなどによってドアパネル３に取り付けられる板状の金具などである。 The mounting portion 8 is a portion provided at the lower end portion of the door panel 3. The mounting portion 8 is, for example, a plate-shaped metal fitting that is mounted on the door panel 3 with a screw or the like.
　摺動部９は、敷居溝６に上方から挿し込まれるように配置される部分である。摺動部９は、取付部８の下端部に取り付けられる。摺動部９は、例えば樹脂によって形成される。摺動部９の下面９ａは、敷居溝６の上端より下方に配置される。摺動部９の側面９ｂは、敷居溝６の側壁７に対向する。摺動部９の上面９ｃは、敷居溝６の上端より上方または下方のいずれに配置されてもよい。 The sliding portion 9 is a portion arranged so as to be inserted into the threshold groove 6 from above. The sliding portion 9 is attached to the lower end portion of the attachment portion 8. The sliding portion 9 is formed of, for example, a resin. The lower surface 9a of the sliding portion 9 is arranged below the upper end of the threshold groove 6. The side surface 9b of the sliding portion 9 faces the side wall 7 of the threshold groove 6. The upper surface 9c of the sliding portion 9 may be arranged either above or below the upper end of the threshold groove 6.
　図３は、実施の形態１に係るドアシュー５の斜視図である。 FIG. 3 is a perspective view of the door shoe 5 according to the first embodiment.
　摺動部９は、第１流路１０を側面９ｂに有する。第１流路１０は、摺動部９の側面９ｂにおいて摺動部９の上面９ｃから下方に延びる。この例において、第１流路１０は、摺動部９の上面９ｃから摺動部９の下面９ａまでに至っている。第１流路１０は、例えば上下に長い凹部である。この例において、第１流路１０は、上下に長い溝である。この例において、摺動部９の水平断面における第１流路１０の形状は、矩形状である。ここで、矩形の各辺は、第１流路１０の底面１０ａまたは側面１０ｂに対応する。 The sliding portion 9 has a first flow path 10 on the side surface 9b. The first flow path 10 extends downward from the upper surface 9c of the sliding portion 9 on the side surface 9b of the sliding portion 9. In this example, the first flow path 10 extends from the upper surface 9c of the sliding portion 9 to the lower surface 9a of the sliding portion 9. The first flow path 10 is, for example, a recess that is long in the vertical direction. In this example, the first flow path 10 is a vertically long groove. In this example, the shape of the first flow path 10 in the horizontal cross section of the sliding portion 9 is rectangular. Here, each side of the rectangle corresponds to the bottom surface 10a or the side surface 10b of the first flow path 10.
　摺動部９は、防汚コーティング層１１を上面９ｃに有する。摺動部９は、防汚コーティング層１１を第１流路１０に有する。防汚コーティング層１１は、防汚コーティングによって形成される層である。防汚コーティングは、表面の疎水性を高めるコーティングである。ここで、表面の疎水性は、例えば水の接触角を指標としてもよい。防汚コーティングは、例えばフッ素樹脂によるコーティングであってもよい。 The sliding portion 9 has an antifouling coating layer 11 on the upper surface 9c. The sliding portion 9 has an antifouling coating layer 11 in the first flow path 10. The antifouling coating layer 11 is a layer formed by the antifouling coating. The antifouling coating is a coating that enhances the hydrophobicity of the surface. Here, the hydrophobicity of the surface may be indexed by, for example, the contact angle of water. The antifouling coating may be, for example, a coating made of a fluororesin.
　続いて、実施の形態１に係るドアシュー５の動作を説明する。 Subsequently, the operation of the door shoe 5 according to the first embodiment will be described.
　ドア１が開閉するときに、ドアシュー５は、敷居溝６に案内される。これにより、ドア１が開閉するときのドアパネル３の傾きが抑えられる。このとき、ドアシュー５の摺動部９の側面９ｂは、敷居溝６の側壁７に接触しながら開閉方向に移動する。第１流路１０によって、摺動部９の側面９ｂにおいて敷居溝６の側壁７に接触する部分の面積は、摺動部９を敷居溝６の側壁７に投影した面積より小さくなる。このため、第１流路１０によって、摺動部９の側面９ｂと敷居溝６の側壁７との間の摩擦抵抗が小さくなる。これにより、ドア１の開閉においてドアシュー５にかかる抵抗が抑えられる。 When the door 1 opens and closes, the door shoe 5 is guided to the threshold groove 6. As a result, the inclination of the door panel 3 when the door 1 is opened and closed is suppressed. At this time, the side surface 9b of the sliding portion 9 of the door shoe 5 moves in the opening / closing direction while contacting the side wall 7 of the threshold groove 6. The area of the portion of the side surface 9b of the sliding portion 9 that contacts the side wall 7 of the sill groove 6 by the first flow path 10 is smaller than the area of the sliding portion 9 projected onto the side wall 7 of the sill groove 6. Therefore, the first flow path 10 reduces the frictional resistance between the side surface 9b of the sliding portion 9 and the side wall 7 of the threshold groove 6. As a result, the resistance applied to the door shoe 5 when opening and closing the door 1 is suppressed.
　また、エレベーターにおいて、敷居４の敷居溝６に液体が入り込むことがある。液体は、例えば乗場またはかごの内部においてこぼれた飲料などである。あるいは、液体は、利用者の傘および履物などに付着していた雨水または泥水などである。このとき、液体は、上方から敷居溝６に入り込む。ここで、敷居溝６に入り込む液体は、ドアシュー５にかかることがある。 Also, in the elevator, liquid may enter the threshold groove 6 of the threshold 4. The liquid is, for example, a beverage spilled inside a landing or a car. Alternatively, the liquid is rainwater or muddy water adhering to the user's umbrella, footwear, or the like. At this time, the liquid enters the threshold groove 6 from above. Here, the liquid that enters the threshold groove 6 may be applied to the door shoe 5.
　ドアシュー５にかかった液体は、ドアシュー５の上面９ｃにかかる。ドアシュー５の上面９ｃの防汚コーティング層１１によって、液体は、滞留することなく流れる。このため、液体は、ドア１の開閉方向におけるドアシュー５の端部から流れ落ちる。また、液体は、上面９ｃから第１流路１０にも流れ込む。第１流路１０の防汚コーティング層１１によって、液体は、滞留することなく第１流路１０を下方に流れ落ちる。 The liquid applied to the door shoe 5 is applied to the upper surface 9c of the door shoe 5. The antifouling coating layer 11 on the upper surface 9c of the door shoe 5 allows the liquid to flow without stagnation. Therefore, the liquid flows down from the end of the door shoe 5 in the opening / closing direction of the door 1. The liquid also flows from the upper surface 9c into the first flow path 10. The antifouling coating layer 11 of the first flow path 10 allows the liquid to flow downward through the first flow path 10 without staying.
　このように、ドアシュー５にかかった液体の滞留が抑えられる。また、第１流路１０によってドアシュー５にかかった液体の滞留が抑えられるので、摺動部９の側面９ｂと敷居溝６の側壁７との間への液体の浸入が抑えられる。このため、ドアシュー５に滞留する液体の粘性抵抗によってドア１の開閉が抵抗を受けることが防がれる。また、ドアシュー５に滞留した液体が時間の経過によって粘着性を持った粘着物になることが防がれる。このため、ドアシュー５に付着した粘着物によってドア１の開閉が抵抗を受けることが防がれる。ここで、ドアシュー５に液体が滞留している場合に、摺動部９の側面９ｂと敷居溝６の側壁７との間に浸入する液体によってドア１の開閉に対する抵抗力が生じる場合がある。この抵抗力は、例えば２枚の平板の間の流体による抵抗力である。２枚の平板の間の抵抗力は、流体に接している平板の面積に比例し、平板の間隔に反比例することが実験的に知られている。ドアシュー５において、第１流路１０によって側壁７に接触する摺動部９の面積が小さくなるので、液体が浸入したとしてもドア１の開閉に対する抵抗力が小さくなる。また、浸入した液体が時間の経過によって粘着性を持った粘着物になった場合にも、粘着物によるドア１の開閉に対する抵抗力が小さくなる。 In this way, the retention of the liquid on the door shoe 5 is suppressed. Further, since the first flow path 10 suppresses the retention of the liquid on the door shoe 5, the infiltration of the liquid between the side surface 9b of the sliding portion 9 and the side wall 7 of the threshold groove 6 is suppressed. Therefore, it is possible to prevent the opening and closing of the door 1 from being resisted by the viscous resistance of the liquid staying in the door shoe 5. Further, it is possible to prevent the liquid staying in the door shoe 5 from becoming a sticky substance with the passage of time. Therefore, it is possible to prevent the opening and closing of the door 1 from being resisted by the adhesive material adhering to the door shoe 5. Here, when the liquid is retained in the door shoe 5, the liquid that infiltrates between the side surface 9b of the sliding portion 9 and the side wall 7 of the threshold groove 6 may cause a resistance force against opening and closing of the door 1. This resistance is, for example, the resistance due to the fluid between the two flat plates. It is experimentally known that the resistance force between two flat plates is proportional to the area of the flat plates in contact with the fluid and inversely proportional to the distance between the flat plates. In the door shoe 5, the area of the sliding portion 9 in contact with the side wall 7 is reduced by the first flow path 10, so that the resistance to opening and closing of the door 1 is reduced even if a liquid infiltrates. Further, even when the infiltrated liquid becomes a sticky substance with the passage of time, the resistance to opening and closing of the door 1 by the sticky substance becomes small.
　以上に説明したように、実施の形態１に係るドアシュー５は、取付部８と、摺動部９と、を備える。取付部８は、エレベーターのドアパネル３の下端部に設けられる。摺動部９は、取付部８に取り付けられる。摺動部９は、敷居溝６に配置される。敷居溝６は、ドア１の開閉方向に長い溝である。摺動部９の側面９ｂは、敷居溝６の側壁７に対向する。摺動部９の側面９ｂにおいて、第１流路１０が設けられる。第１流路１０は、摺動部９の上面９ｃから下方に延びる。 As described above, the door shoe 5 according to the first embodiment includes a mounting portion 8 and a sliding portion 9. The mounting portion 8 is provided at the lower end portion of the door panel 3 of the elevator. The sliding portion 9 is attached to the attachment portion 8. The sliding portion 9 is arranged in the threshold groove 6. The threshold groove 6 is a groove long in the opening / closing direction of the door 1. The side surface 9b of the sliding portion 9 faces the side wall 7 of the threshold groove 6. A first flow path 10 is provided on the side surface 9b of the sliding portion 9. The first flow path 10 extends downward from the upper surface 9c of the sliding portion 9.
　これにより、ドアシュー５に液体が滞留しにくくなる。このため、ドアシュー５は、液体の粘性抵抗などによって抵抗を受けにくくなる。 This makes it difficult for the liquid to stay in the door shoe 5. Therefore, the door shoe 5 is less likely to receive resistance due to the viscous resistance of the liquid or the like.
　また、摺動部９の側面９ｂにおいて、第１流路１０は、摺動部９の上面９ｃから摺動部９の下面９ａまでに至っている。このため、第１流路１０を流れる液体は、摺動部９の下方に排出される。摺動部９の下方に排出された液体は、摺動部９に再びかかりにくい。このため、ドアシュー５は、液体の粘性抵抗などによる抵抗をより受けにくくなる。 Further, on the side surface 9b of the sliding portion 9, the first flow path 10 extends from the upper surface 9c of the sliding portion 9 to the lower surface 9a of the sliding portion 9. Therefore, the liquid flowing through the first flow path 10 is discharged below the sliding portion 9. The liquid discharged below the sliding portion 9 is unlikely to be applied to the sliding portion 9 again. Therefore, the door shoe 5 is less likely to receive resistance due to the viscous resistance of the liquid or the like.
　なお、第１流路１０は、摺動部９の上面９ｃから、開閉方向における摺動部９の端部の下部などに至るように延びていてもよい。摺動部９が移動する方向の後側から第１流路１０を流れる液体が排出されるときに、排出された液体は、ドア１が開閉するときに移動している摺動部９に再びかかりにくくなる。 The first flow path 10 may extend from the upper surface 9c of the sliding portion 9 to the lower portion of the end portion of the sliding portion 9 in the opening / closing direction. When the liquid flowing through the first flow path 10 is discharged from the rear side in the direction in which the sliding portion 9 moves, the discharged liquid is returned to the sliding portion 9 which is moving when the door 1 opens and closes. It becomes difficult to take.
　また、摺動部９は、防汚コーティング層１１を上面９ｃに有する。これにより、摺動部９の上面９ｃに液体がより滞留しにくくなる。 Further, the sliding portion 9 has an antifouling coating layer 11 on the upper surface 9c. As a result, the liquid is less likely to stay on the upper surface 9c of the sliding portion 9.
　また、摺動部９は、防汚コーティング層１１を第１流路１０に有する。これにより、第１流路１０に液体がより滞留しにくくなる。また、ドア１の開閉方向における第１流路１０の幅が狭い場合においても、液体は、第１流路１０を速やかに流れ落ちるようになる。このため、液体の粘着物への変化がより効果的に防がれる。 Further, the sliding portion 9 has an antifouling coating layer 11 in the first flow path 10. As a result, the liquid is less likely to stay in the first flow path 10. Further, even when the width of the first flow path 10 in the opening / closing direction of the door 1 is narrow, the liquid quickly flows down the first flow path 10. Therefore, the change of the liquid into a sticky substance can be prevented more effectively.
　なお、摺動部９は、防汚コーティング層１１を有していなくてもよい。このとき、液体の滞留は、例えば摺動部９を形成する樹脂などの材質そのものの疎水性によって防がれてもよい。また、防汚コーティング層１１は、摺動部９の上面９ｃまたは第１流路１０のいずれか一方に設けられてもよい。あるいは、防汚コーティング層１１は、摺動部９の全面に設けられてもよい。 The sliding portion 9 does not have to have the antifouling coating layer 11. At this time, the retention of the liquid may be prevented by the hydrophobicity of the material itself such as the resin forming the sliding portion 9. Further, the antifouling coating layer 11 may be provided on either the upper surface 9c of the sliding portion 9 or the first flow path 10. Alternatively, the antifouling coating layer 11 may be provided on the entire surface of the sliding portion 9.
　この例において、摺動部９は、ｙｚ平面に平行な鉛直面に関して対称に構成される。摺動部９は、敷居溝６の側壁７に対向する両側の側面９ｂにおいて、互いに対称に第１流路１０を有する。ここで、摺動部９は、両側の側面９ｂにおいて、互いに非対称に第１流路１０を有していてもよい。また、摺動部９は、一方の側面９ｂにのみ第１流路１０を有していてもよい。例えば、ドア１がかごドアである場合に、摺動部９は、かごの内側を向く側面９ｂにのみ第１流路１０を有していてもよい。あるいは、ドア１が乗場ドアである場合に、摺動部９は、乗場の側を向く側面９ｂにのみ第１流路１０を有していてもよい。 In this example, the sliding portion 9 is symmetrically configured with respect to the vertical plane parallel to the yz plane. The sliding portion 9 has a first flow path 10 symmetrically with respect to each other on the side surface 9b on both sides facing the side wall 7 of the threshold groove 6. Here, the sliding portion 9 may have the first flow path 10 asymmetrically with each other on the side surfaces 9b on both sides. Further, the sliding portion 9 may have a first flow path 10 only on one side surface 9b. For example, when the door 1 is a car door, the sliding portion 9 may have the first flow path 10 only on the side surface 9b facing the inside of the car. Alternatively, when the door 1 is a landing door, the sliding portion 9 may have the first flow path 10 only on the side surface 9b facing the landing side.
　また、エレベーターのドア１は、片開きのドアであってもよい。エレベーターのドア１は、ドア１が開閉するときに同じ方向に移動する複数のドアパネル３を備える２枚戸または３枚戸などのドアであってもよい。 Further, the elevator door 1 may be a single door. The door 1 of the elevator may be a door such as a two-door or a three-door having a plurality of door panels 3 that move in the same direction when the door 1 opens and closes.
　続いて、図４を用いて、実施の形態１の変形例を説明する。
　図４は、実施の形態１の変形例に係るドアシューの斜視図である。 Subsequently, a modified example of the first embodiment will be described with reference to FIG.
FIG. 4 is a perspective view of the door shoe according to the modified example of the first embodiment.
　この例において、摺動部９の水平断面における第１流路１０の形状は、台形状である。ここで、台形の上底または下底は、第１流路１０の底面１０ａに対応する。台形の斜辺は、第１流路１０の側面１０ｂに対応する。 In this example, the shape of the first flow path 10 in the horizontal cross section of the sliding portion 9 is trapezoidal. Here, the upper or lower base of the trapezoid corresponds to the bottom surface 10a of the first flow path 10. The trapezoidal hypotenuse corresponds to the side surface 10b of the first flow path 10.
　摺動部９において、第１流路１０は、ドア１の開閉方向における幅が外側に向けて広がるように設けられる。この例において、第１流路１０の側面１０ｂは、第１流路１０の底面１０ａに対して鈍角をなすように形成される。これにより、表面張力などによって液体が第１流路１０に滞留することが防がれる。 In the sliding portion 9, the first flow path 10 is provided so that the width of the door 1 in the opening / closing direction widens toward the outside. In this example, the side surface 10b of the first flow path 10 is formed so as to form an obtuse angle with respect to the bottom surface 10a of the first flow path 10. This prevents the liquid from staying in the first flow path 10 due to surface tension or the like.
　なお、第１流路１０は、摺動部９の水平断面における形状が台形状である溝に限定されない。第１流路１０は、例えば摺動部９の水平断面における形状が円弧状などの滑らかな形状の溝であってもよい。第１流路１０の形状は、ｘｙ平面に平行な鉛直面に関して非対称な形状であってもよい。 The first flow path 10 is not limited to a groove having a trapezoidal shape in the horizontal cross section of the sliding portion 9. The first flow path 10 may be a groove having a smooth shape such as an arc shape in the horizontal cross section of the sliding portion 9, for example. The shape of the first flow path 10 may be asymmetric with respect to the vertical plane parallel to the xy plane.
　続いて、図５を用いて、実施の形態１の他の変形例を説明する。
　図５は、実施の形態１の変形例に係るドアシューの斜視図である。 Subsequently, another modification of the first embodiment will be described with reference to FIG.
FIG. 5 is a perspective view of the door shoe according to the modified example of the first embodiment.
　摺動部９は、微細構造を上面９ｃに有する。摺動部９は、微細構造を第１流路１０に有する。微細構造は、例えば表面構造に基づくロータス効果などによって表面の疎水性を高める構造である。微細構造は、例えば表面に並ぶ微小突起１２である。微小突起１２の大きさは、例えばマイクロメートルのオーダーである。なお、図５において、微小突起１２は図示のため拡大されている。 The sliding portion 9 has a fine structure on the upper surface 9c. The sliding portion 9 has a fine structure in the first flow path 10. The microstructure is a structure that enhances the hydrophobicity of the surface by, for example, the Lotus effect based on the surface structure. The microstructure is, for example, microprojections 12 lined up on the surface. The size of the microprojections 12 is, for example, on the order of micrometers. In FIG. 5, the microprojection 12 is enlarged for illustration purposes.
　このように、摺動部９は、疎水性を高める微細構造を上面９ｃに有する。これにより、摺動部９の上面９ｃに液体がより滞留しにくくなる。 As described above, the sliding portion 9 has a fine structure on the upper surface 9c that enhances hydrophobicity. As a result, the liquid is less likely to stay on the upper surface 9c of the sliding portion 9.
　また、摺動部９は、疎水性を高める微細構造を第１流路１０に有する。これにより、第１流路１０に液体がより滞留しにくくなる。また、ドア１の開閉方向における第１流路１０の幅が狭い場合においても、液体は第１流路１０を速やかに流れ落ちるようになる。このため、液体の粘着物への変化がより効果的に防がれる。 Further, the sliding portion 9 has a fine structure in the first flow path 10 that enhances hydrophobicity. As a result, the liquid is less likely to stay in the first flow path 10. Further, even when the width of the first flow path 10 in the opening / closing direction of the door 1 is narrow, the liquid quickly flows down the first flow path 10. Therefore, the change of the liquid into a sticky substance can be prevented more effectively.
　なお、微細構造は、摺動部９の上面９ｃまたは第１流路１０のいずれか一方に設けられてもよい。あるいは、微細構造は、摺動部９の全面に設けられてもよい。摺動部９が防汚コーティング層１１を有する場合に、微細構造は、防汚コーティング層１１に設けられていてもよい。 The microstructure may be provided on either the upper surface 9c of the sliding portion 9 or the first flow path 10. Alternatively, the microstructure may be provided on the entire surface of the sliding portion 9. When the sliding portion 9 has the antifouling coating layer 11, the microstructure may be provided on the antifouling coating layer 11.
　続いて、図６を用いて、実施の形態１の他の変形例を説明する。
　図６は、実施の形態１の変形例に係るドアシューの斜視図である。 Subsequently, another modification of the first embodiment will be described with reference to FIG.
FIG. 6 is a perspective view of the door shoe according to the modified example of the first embodiment.
　摺動部９の第１流路１０が設けられる側面において、さらに第２流路１３が設けられる。第２流路１３は、摺動部９の上面９ｃから下方に延びる。第２流路１３は、例えば上下に長い凹部である。この例において、第２流路１３は、上下に長い溝である。これにより、ドアシュー５にかかる液体は、第１流路１０および第２流路１３のいずれからも流れ落ちるようになる。このため、ドアシュー５において液体がより滞留しにくくなる。 A second flow path 13 is further provided on the side surface of the sliding portion 9 where the first flow path 10 is provided. The second flow path 13 extends downward from the upper surface 9c of the sliding portion 9. The second flow path 13 is, for example, a vertically long recess. In this example, the second flow path 13 is a vertically long groove. As a result, the liquid applied to the door shoe 5 flows down from both the first flow path 10 and the second flow path 13. Therefore, the liquid is less likely to stay in the door shoe 5.
　この例において、第２流路１３は、摺動部９の上面９ｃから摺動部９の下面９ａまでに至っている。第２流路１３は、例えば第１流路１０と同様に形成される。 In this example, the second flow path 13 extends from the upper surface 9c of the sliding portion 9 to the lower surface 9a of the sliding portion 9. The second flow path 13 is formed in the same manner as the first flow path 10, for example.
　なお、摺動部９の側面９ｂにおいて、上面９ｃから下方に延びる流路が３つ以上設けられていてもよい。 Note that, on the side surface 9b of the sliding portion 9, three or more flow paths extending downward from the upper surface 9c may be provided.
　続いて、図７を用いて、実施の形態１の他の変形例を説明する。
　図７は、実施の形態１の変形例に係るドアシューの斜視図である。 Subsequently, another modification of the first embodiment will be described with reference to FIG. 7.
FIG. 7 is a perspective view of the door shoe according to the modified example of the first embodiment.
　第１流路１０のｘ方向の深さは、摺動部９の側面９ｂから取付部８にまで至る深さであってもよい。この例において、摺動部９は、第１部分１４ａおよび第２部分１４ｂを有する。第１部分１４ａおよび第２部分１４ｂは、ドア１の開閉方向において分割された摺動部９の２つの部分である。第１流路１０は、第１部分１４ａおよび第２部分１４ｂの間の隙間であってもよい。 The depth of the first flow path 10 in the x direction may be a depth extending from the side surface 9b of the sliding portion 9 to the mounting portion 8. In this example, the sliding portion 9 has a first portion 14a and a second portion 14b. The first portion 14a and the second portion 14b are two portions of the sliding portion 9 divided in the opening / closing direction of the door 1. The first flow path 10 may be a gap between the first portion 14a and the second portion 14b.
　実施の形態２．
　実施の形態２において、実施の形態１で開示される例と相違する点について特に詳しく説明する。実施の形態２で説明しない特徴については、実施の形態１で開示される例のいずれの特徴が採用されてもよい。 Embodiment 2.
The differences between the second embodiment and the examples disclosed in the first embodiment will be described in particular detail. As for the features not described in the second embodiment, any of the features disclosed in the first embodiment may be adopted.
　図８は、実施の形態２に係るドアシューの斜視図である。 FIG. 8 is a perspective view of the door shoe according to the second embodiment.
　摺動部９の第１流路１０が設けられる側面９ｂにおいて、さらに２箇所の横流路１５が設けられる。横流路１５は、ドア１の開閉方向に延びる。横流路１５は、例えば水平方向に長い溝である。２箇所の横流路１５の各々は、第１流路１０に接続する。一方の横流路１５は、摺動部９のｚ軸の正の側の端部に接続する。他方の横流路１５は、摺動部９のｚ軸の負の側の端部に接続する。 On the side surface 9b where the first flow path 10 of the sliding portion 9 is provided, two further lateral flow paths 15 are provided. The transverse flow path 15 extends in the opening / closing direction of the door 1. The transverse flow path 15 is, for example, a groove long in the horizontal direction. Each of the two lateral flow paths 15 is connected to the first flow path 10. One lateral flow path 15 is connected to the end of the sliding portion 9 on the positive side of the z-axis. The other transverse flow path 15 is connected to the end of the sliding portion 9 on the negative side of the z-axis.
　横流路１５によって、摺動部９の側面９ｂにおいて敷居溝６の側壁７に接触する部分の面積はさらに小さくなる。このため、横流路１５によって、摺動部９の側面９ｂと敷居溝６の側壁７との間の摩擦抵抗がさらに小さくなる。これにより、ドア１の開閉においてドアシュー５にかかる抵抗がさらに抑えられる。また、液体粘着物が敷居溝６の側壁７と摺動部９の側面９ｂ間に滞留した場合にも、滞留した液体粘着物によるドア１の開閉に対する抵抗力が小さくなる。 The area of the portion of the side surface 9b of the sliding portion 9 in contact with the side wall 7 of the threshold groove 6 is further reduced by the lateral flow path 15. Therefore, the lateral flow path 15 further reduces the frictional resistance between the side surface 9b of the sliding portion 9 and the side wall 7 of the threshold groove 6. As a result, the resistance applied to the door shoe 5 when opening and closing the door 1 is further suppressed. Further, even when the liquid adhesive material stays between the side wall 7 of the threshold groove 6 and the side surface 9b of the sliding portion 9, the resistance to opening and closing of the door 1 by the accumulated liquid adhesive material becomes small.
　続いて、図９を用いて、実施の形態２の変形例を説明する。
　図９は、実施の形態２の変形例に係るドアシューの斜視図である。 Subsequently, a modified example of the second embodiment will be described with reference to FIG.
FIG. 9 is a perspective view of the door shoe according to the modified example of the second embodiment.
　摺動部９において、２箇所の横流路１５は、第１流路１０に接続している。２箇所の横流路１５は、第１流路１０に向けて下がるように傾斜している。これにより、液体が横流路１５に浸入した場合においても、液体は第１流路１０から速やかに排出される。 In the sliding portion 9, the two lateral flow paths 15 are connected to the first flow path 10. The two lateral flow paths 15 are inclined so as to descend toward the first flow path 10. As a result, even when the liquid has entered the lateral flow path 15, the liquid is quickly discharged from the first flow path 10.
　続いて、図１０を用いて、実施の形態２の他の変形例を説明する。
　図１０は、実施の形態２の変形例に係るドアシューの斜視図である。 Subsequently, another modification of the second embodiment will be described with reference to FIG.
FIG. 10 is a perspective view of the door shoe according to the modified example of the second embodiment.
　摺動部９において、一方の横流路１５は、摺動部９のｚ軸の正の側の端部に接続する。他方の横流路１５は、摺動部９のｚ軸の負の側の端部に接続する。ｚ軸の正の側の端部に接続する横流路１５は、当該端部に向けて下がるように傾斜している。ｚ軸の負の側の端部に接続する横流路１５は、当該端部に向けて下がるように傾斜している。これにより、液体が横流路１５に浸入した場合においても、液体はドア１の開閉方向における摺動部９の端部から速やかに排出される。 In the sliding portion 9, one lateral flow path 15 is connected to the end of the sliding portion 9 on the positive side of the z-axis. The other transverse flow path 15 is connected to the end of the sliding portion 9 on the negative side of the z-axis. The transverse flow path 15 connected to the positive end of the z-axis is inclined so as to be lowered toward the end. The transverse flow path 15 connected to the end on the negative side of the z-axis is inclined so as to be lowered toward the end. As a result, even when the liquid enters the lateral flow path 15, the liquid is quickly discharged from the end of the sliding portion 9 in the opening / closing direction of the door 1.
