The door stopper 10 may be provided at a corner of the door P on one side surface P1 side of the upper surface P4. Hereinafter, a door stopper 10 provided at a corner on one side surface P1 side of the lower surface P3 of the door P will be described as an example.

図２に示されるように、扉ストッパ１０は、例えば、扉Ｐの下面Ｐ３側に設けられた固定部材１４と、固定部材１４に対して移動する本体部１１と、本体部１１に連動して床面Ｅ方向に突出する突出部１５と、床面Ｅ側に設けられた受部２０とを備える。 As shown in FIG. 2, the door stopper 10 is interlocked with, for example, a fixing member 14 provided on the lower surface P3 side of the door P, a main body portion 11 moving with respect to the fixing member 14, and the main body portion 11. A projecting portion 15 projecting in the floor surface E direction and a receiving portion 20 provided on the floor surface E side are provided.

固定部材１４は、例えば、扉Ｐの下面Ｐ３側から内部方向に向かって形成された空間Ｓ内に固定されている。固定部材１４は、本体部１１を収容する収容部１４Ａを備える。収容部１４Ａは、例えば、矩形断面の筒状体に形成されている。収容部１４Ａには、空間Ｓの壁面に固定するための板状部１４Ｂが形成されている。 The fixing member 14 is fixed in, for example, the space S formed inward from the lower surface P3 side of the door P. The fixing member 14 includes an accommodating portion 14A for accommodating the main body portion 11. The accommodating portion 14A is formed, for example, in a cylindrical body having a rectangular cross section. The accommodating portion 14A is formed with a plate-shaped portion 14B for fixing to the wall surface of the space S.

板状部１４Ｂは、収容部１４Ａの長手方向に沿って矩形の板状に形成されている。板状部１４Ｂは、収容部１４Ａの一面と同一面であるように収容部１４Ａの短手方向に突出して形成されている。板状部１４Ｂには、空間Ｓの壁面にビス等によって固定するためのビス穴１４Ｃが形成されている。収容部１４Ａには、本体部１１を収容する円形断面の貫通孔１４Ｈが形成されている。収容部１４Ａには、本体部１１が挿入される。 The plate-shaped portion 14B is formed in a rectangular plate shape along the longitudinal direction of the accommodating portion 14A. The plate-shaped portion 14B is formed so as to project on the lateral side of the accommodating portion 14A so as to be flush with one surface of the accommodating portion 14A. The plate-shaped portion 14B is formed with a screw hole 14C for fixing to the wall surface of the space S by a screw or the like. The accommodating portion 14A is formed with a through hole 14H having a circular cross section for accommodating the main body portion 11. The main body 11 is inserted into the accommodating portion 14A.

本体部１１は、例えば、円筒状に形成されている。本体部１１は、貫通孔１４Ｈの径に比して若干細い径に形成されている。本体部１１には、軸線Ｑ方向に沿って貫通したネジ穴１２が形成されている。ネジ穴１２は、貫通していなくてもよく、本体部１１の両端において所定の深さに形成されていてもよい。本体部１１は、例えば、ステンレス鋼等の非磁性体によって形成されている。本体部１１には、連動して移動する突出部１５が設けられている。 The main body 11 is formed in a cylindrical shape, for example. The main body 11 is formed to have a diameter slightly smaller than the diameter of the through hole 14H. The main body 11 is formed with a screw hole 12 penetrating along the axis Q direction. The screw holes 12 do not have to penetrate, and may be formed at both ends of the main body 11 to a predetermined depth. The main body 11 is formed of, for example, a non-magnetic material such as stainless steel. The main body 11 is provided with a protrusion 15 that moves in conjunction with the main body 11.

突出部１５は、本体部１１の一端１１Ａ側に軸線Ｑ方向に沿って設けられている。突出部１５は、例えば、円柱状に形成された移動部１７と、移動部１７を覆う摩擦部材１７Ｍとを備える。移動部１７は、ネジ１７Ｂを介して本体部１１の一端１１Ａ側に固定されている。ネジ１７Ｂは、ネジ穴１２に螺入される。上記構成により、突出部１５は、扉Ｐに対して突出自在に設けられている。 The protruding portion 15 is provided on one end 11A side of the main body portion 11 along the axis Q direction. The protruding portion 15 includes, for example, a moving portion 17 formed in a columnar shape and a friction member 17M covering the moving portion 17. The moving portion 17 is fixed to one end 11A side of the main body portion 11 via a screw 17B. The screw 17B is screwed into the screw hole 12. According to the above configuration, the protruding portion 15 is provided so as to be able to project with respect to the door P.

本体部１１の他端側には、軸線Ｑ方向に沿ってシャフト１６が設けられている。シャフト１６は、円柱状に形成されている。シャフト１６の一端１６Ａ側にはネジ溝１６Ｃが形成されている。シャフト１６の一端１６Ａ側は、本体部１１のネジ穴１２に螺入され、固定されている。 A shaft 16 is provided on the other end side of the main body 11 along the axis Q direction. The shaft 16 is formed in a columnar shape. A screw groove 16C is formed on one end 16A side of the shaft 16. One end 16A side of the shaft 16 is screwed into the screw hole 12 of the main body 11 and fixed.

シャフト１６の他端１６Ｂ側には、シャフト１６の外形に比して太い円柱状に形成された脱落防止部材１８が設けられている。シャフト１６の他端１６Ｂ側には、ネジ溝１６Ｄが形成されている。脱落防止部材１８には、ネジ穴が形成されている。施工性、部品製造の観点から、シャフト１６の他端１６Ｂ側は、脱落防止部材１８のネジ穴に螺入され、固定される。シャフト１６と脱落防止部材１８は、嵌入により固定されてもよい。シャフト１６と脱落防止部材１８は、スポット溶接、嵌入、焼き嵌め、冷やし嵌め、接着剤、ピン止め等によって固定されてもよい。シャフト１６は、コイル状のバネによって形成された弾性部材１９に挿入されている。弾性部材１９は、シャフト１６の周囲において脱落防止部材１８と本体部１１との間に配置されている。 On the other end 16B side of the shaft 16, a dropout prevention member 18 formed in a columnar shape that is thicker than the outer shape of the shaft 16 is provided. A screw groove 16D is formed on the other end 16B side of the shaft 16. A screw hole is formed in the fall prevention member 18. From the viewpoint of workability and parts manufacturing, the other end 16B side of the shaft 16 is screwed into the screw hole of the fall prevention member 18 and fixed. The shaft 16 and the fall prevention member 18 may be fixed by fitting. The shaft 16 and the fall prevention member 18 may be fixed by spot welding, fitting, shrink fitting, cold fitting, adhesive, pinning, or the like. The shaft 16 is inserted into an elastic member 19 formed by a coiled spring. The elastic member 19 is arranged around the shaft 16 between the fall prevention member 18 and the main body 11.

弾性部材１９と本体部１１との間には、ドーナッツ板状に形成されたワッシャ１３が挿入されている。ワッシャ１３は、本体部１１の外形に比して大きい外形に形成されている。弾性部材１９は、全長を短縮した状態において脱落防止部材１８と本体部１１との間に挿入されている。弾性部材１９は、ワッシャ１３と脱落防止部材１８とを押圧している。弾性部材１９は、ワッシャ１３と後述の移動部１７におけるフランジ部１７Ｆとが収容部１４Ａを挟持するように付勢している。弾性部材１９は、突出部１５（移動部１７）を扉Ｐ側に収納する方向に付勢し、本体部１１を所定位置に保持している。弾性部材１９の形状及び材質は一例であり、突出部１５を扉Ｐ側に収納する方向に付勢できるのであれば、他の形状に形成され、他の材質によって形成されていてもよい。 A washer 13 formed in a donut plate shape is inserted between the elastic member 19 and the main body 11. The washer 13 is formed to have a larger outer shape than the outer shape of the main body 11. The elastic member 19 is inserted between the fall prevention member 18 and the main body 11 in a state where the total length is shortened. The elastic member 19 presses the washer 13 and the fall prevention member 18. The elastic member 19 is urged so that the washer 13 and the flange portion 17F in the moving portion 17 described later sandwich the accommodating portion 14A. The elastic member 19 urges the protruding portion 15 (moving portion 17) to be housed in the door P side, and holds the main body portion 11 at a predetermined position. The shape and material of the elastic member 19 is an example, and if the protruding portion 15 can be urged in the direction of accommodating the door P side, the elastic member 19 may be formed in another shape and may be formed of another material.

移動部１７は、本体部１１と略同じシャフト１６に比して大きい外形の円柱状に形成されている。移動部１７において、本体部１１側には、本体部１１に比して外形が大きいフランジ部１７Ｆが形成されている。移動部１７は、例えば、内部に磁石を備える。移動部１７は、磁石によって形成されていてもよい。移動部１７は、例えば、ネオジム磁石等の強力な磁力を発生する磁石を有することが望ましい。移動部１７の表面は、ゴム等によって形成された摩擦部材１７Ｍによって覆われている。摩擦部材１７Ｍは、床面Ｅの材質によっては省略されてもよい。 The moving portion 17 is formed in a columnar shape having a larger outer shape than the shaft 16 which is substantially the same as the main body portion 11. In the moving portion 17, a flange portion 17F having a larger outer shape than the main body portion 11 is formed on the main body portion 11 side. The moving unit 17 is provided with, for example, a magnet inside. The moving portion 17 may be formed by a magnet. It is desirable that the moving portion 17 has a magnet that generates a strong magnetic force, such as a neodymium magnet. The surface of the moving portion 17 is covered with a friction member 17M formed of rubber or the like. The friction member 17M may be omitted depending on the material of the floor surface E.

図３に示されるように、扉Ｐが相対的に移動する面側（床面Ｅ側）の所定位置には、受部２０が設けられている。所定位置は、床面Ｅにおいて扉Ｐが開口Ｒを閉じた状態における突出部１５に対応する位置である。受部２０は、床面Ｅ側に埋め込まれている。受部２０は、床面Ｅと同一面であるように形成されている。受部２０は、例えば、鉄等の磁性体によって形成されている。受部２０は、移動部１７が所定位置に移動した際に、移動部１７との間に発生する磁気吸引力によって移動部１７を突出させ移動部１７と磁気吸着する。受部２０と移動部１７とが磁気吸着すると、扉Ｐが開口Ｒを覆った状態において固定される。 As shown in FIG. 3, a receiving portion 20 is provided at a predetermined position on the surface side (floor surface E side) where the door P relatively moves. The predetermined position is a position corresponding to the protrusion 15 when the door P closes the opening R on the floor surface E. The receiving portion 20 is embedded in the floor surface E side. The receiving portion 20 is formed so as to be flush with the floor surface E. The receiving portion 20 is formed of, for example, a magnetic material such as iron. When the moving unit 17 moves to a predetermined position, the receiving unit 20 projects the moving unit 17 by the magnetic attraction generated between the moving unit 17 and magnetically attracts the moving unit 17. When the receiving portion 20 and the moving portion 17 are magnetically attracted, the door P is fixed in a state of covering the opening R.

弾性部材１９は、突出部１５を扉Ｐ側に収納する方向に付勢すると共に、所定位置における移動部１７と受部２０との間に生じる磁気吸引力に比して弱くなるように付勢力が調整されている。弾性部材１９は、所定位置において突出部１５を扉Ｐ側に収納する方向に付勢して伸長した状態から、移動部１７と受部２０との間に生じる磁気吸引力によって短縮する。 The elastic member 19 urges the protruding portion 15 in the direction of accommodating it on the door P side, and also urges the elastic member 19 so as to be weaker than the magnetic attraction generated between the moving portion 17 and the receiving portion 20 at a predetermined position. Has been adjusted. The elastic member 19 is shortened by the magnetic attraction generated between the moving portion 17 and the receiving portion 20 from the state in which the protruding portion 15 is urged and extended in the direction of accommodating the protruding portion 15 on the door P side at a predetermined position.

図４に示されるように、移動部１７が所定位置に位置した際に、移動部１７は、収容部１４Ａ側（扉Ｐ側）に対して突出し、本体部１１及びシャフト１６も連動して収容部１４Ａに対して摺動し、本体部１１の一部が収容部１４Ａから突出する。脱落防止部材１８は、ワッシャ１３側に近位して弾性部材１９を短縮させる。摩擦部材１７Ｍは、移動部１７と受部２０とが磁気吸着した際に、受部２０と接触して受部２０と移動部１７との間に摩擦力を生じさせる。摩擦部材１７Ｍは、ゴム等によって形成されているため、床面Ｅが傷付くことを防止することができる。 As shown in FIG. 4, when the moving portion 17 is positioned at a predetermined position, the moving portion 17 protrudes with respect to the accommodating portion 14A side (door P side), and the main body portion 11 and the shaft 16 are also accommodated in conjunction with each other. It slides with respect to the portion 14A, and a part of the main body portion 11 protrudes from the accommodating portion 14A. The fall prevention member 18 shortens the elastic member 19 proximal to the washer 13 side. When the moving portion 17 and the receiving portion 20 are magnetically attracted to each other, the friction member 17M comes into contact with the receiving portion 20 to generate a frictional force between the receiving portion 20 and the moving portion 17. Since the friction member 17M is made of rubber or the like, it is possible to prevent the floor surface E from being damaged.

上記構成によって、扉ストッパ１０は、開口Ｒに枠が設けられていなくても扉Ｐの閉状態を保持できる。扉ストッパ１０は、扉Ｐの開状態を保持するように、受部２０が扉Ｐの開状態における移動部１７の位置に対応した所定位置に設けられていてもよい。 With the above configuration, the door stopper 10 can hold the closed state of the door P even if the opening R is not provided with the frame. The door stopper 10 may be provided at a predetermined position corresponding to the position of the moving portion 17 in the open state of the door P so that the receiving portion 20 holds the open state of the door P.

摩擦部材１７Ｍと床面Ｅとの間に生じる摩擦力、及び受部２０と移動部１７との間に生じる磁気吸引力に比して強い力が加えられて扉Ｐが閉状態から移動された場合、移動部１７が所定位置から離れる。所定位置以外の場所においては、受部２０と移動部１７との間に生じる磁気吸引力が無くなり、弾性部材１９は、自体の付勢力によって伸長し、脱落防止部材１８を上方に移動させる。移動部１７は、本体部１１及びシャフト１６を介して脱落防止部材１８と連動して上方に移動し、扉Ｐ側に収納される（図２参照）。 The door P was moved from the closed state by applying a stronger force than the frictional force generated between the friction member 17M and the floor surface E and the magnetic attraction force generated between the receiving portion 20 and the moving portion 17. In the case, the moving portion 17 is separated from the predetermined position. At a place other than the predetermined position, the magnetic attraction generated between the receiving portion 20 and the moving portion 17 disappears, the elastic member 19 expands due to its own urging force, and the fall-out preventing member 18 is moved upward. The moving portion 17 moves upward in conjunction with the fall prevention member 18 via the main body portion 11 and the shaft 16, and is housed on the door P side (see FIG. 2).

上記実施形態においては、突出部１５側に磁石が設けられているものを例示したが、磁石は、受部２０側に設けられていてもよい。即ち、磁石は、突出部１５側或いは受部２０側に設けられていればよい。この場合、磁性体は、突出部１５側及び受部２０側のうち磁石が設けられていない、いずれかの側に設けられていればよい。この他、磁石は、突出部１５側に加えて受部２０側にも設けられていてもよい。即ち、突出部１５側に第１磁石が設けられている場合に、受部２０側に第１磁石と磁気吸着する第２磁石が設けられていてもよい。この場合、第１磁石と第２磁石とは、磁極同士が引き合うようにそれぞれ異なる磁極が対向するように配置される。 In the above embodiment, the magnet provided on the protruding portion 15 side is exemplified, but the magnet may be provided on the receiving portion 20 side. That is, the magnet may be provided on the protruding portion 15 side or the receiving portion 20 side. In this case, the magnetic material may be provided on either side of the projecting portion 15 side and the receiving portion 20 side, on which the magnet is not provided. In addition, the magnet may be provided on the receiving portion 20 side in addition to the protruding portion 15 side. That is, when the first magnet is provided on the protruding portion 15 side, the second magnet that magnetically attracts the first magnet may be provided on the receiving portion 20 side. In this case, the first magnet and the second magnet are arranged so that different magnetic poles face each other so that the magnetic poles attract each other.

扉ストッパ１０は、扉Ｐの上面側に設けられ、扉Ｐが相対的に移動する天井面Ｔ（図１参照）に対して固定されてもよい。扉ストッパ１０は、扉Ｐの上面側に設けられている場合、突出部１５が重力によって扉Ｐ側に収納されるので弾性部材１９を省略してもよい。 The door stopper 10 may be provided on the upper surface side of the door P and may be fixed to the ceiling surface T (see FIG. 1) in which the door P moves relatively. When the door stopper 10 is provided on the upper surface side of the door P, the elastic member 19 may be omitted because the protruding portion 15 is housed on the door P side by gravity.

上述したように、建具１、及び扉ストッパ１０によれば、開口Ｒに枠が設けられていなくても平坦な床面Ｅ或いは天井面Ｔに対して扉Ｐを閉状態或いは開状態に保持することができる。扉ストッパ１０によれば、突出部１５と受部２０との間に生じる磁気吸引力によって突出部１５と受部２０とが磁気吸着するため、受部２０側に凹み等の加工が必要無く、床面Ｅと同一面に形成でき、意匠性を向上させることができる。扉ストッパ１０によれば、突出部１５と受部２０との間に設けられた摩擦部材１７Ｍによって摩擦力を生じさせるため、扉Ｐの閉状態或いは開状態を確実に保持することができる。 As described above, according to the fitting 1 and the door stopper 10, the door P is held in the closed state or the open state with respect to the flat floor surface E or the ceiling surface T even if the opening R is not provided with the frame. be able to. According to the door stopper 10, since the protruding portion 15 and the receiving portion 20 are magnetically attracted by the magnetic attraction generated between the protruding portion 15 and the receiving portion 20, there is no need to process a dent or the like on the receiving portion 20 side. It can be formed on the same surface as the floor surface E, and the design can be improved. According to the door stopper 10, the friction member 17M provided between the projecting portion 15 and the receiving portion 20 generates a frictional force, so that the closed state or the open state of the door P can be reliably maintained.

以上、本開示の一実施形態について説明した。本開示は上記の一実施形態に限定されるものではなく、適宜変更、置換が可能である。扉Ｐは、一対でなくてもよく、１枚扉であってもよい。例えば、一対の扉Ｐは、面積が対称でなくてもよい。 The embodiment of the present disclosure has been described above. The present disclosure is not limited to the above embodiment, and can be appropriately modified or substituted. The doors P may not be a pair, but may be a single door. For example, the pair of doors P do not have to be symmetrical in area.

扉ストッパ１０は、本体部１１が磁性体によって形成されている場合、突出部１５が磁気吸引力によって本体部１１に吸着し扉Ｐ側に収納されるので弾性部材１９を省略してもよい。この場合、突出部１５と本体部１１との間に生じる第１磁気吸引力に比して突出部１５と受部２０との間に生じる第２磁気吸引力が強力であるように第１磁気吸引力が調整される。 When the main body 11 is formed of a magnetic material, the door stopper 10 may omit the elastic member 19 because the protruding portion 15 is attracted to the main body 11 by magnetic attraction and is housed in the door P side. In this case, the first magnetic force is stronger so that the second magnetic attraction force generated between the protrusion 15 and the receiving portion 20 is stronger than the first magnetic attraction force generated between the protrusion 15 and the main body 11. The suction power is adjusted.
