以下、本発明を実施するための好適な実施形態について、図面に基づいて説明する。 DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments for carrying out the invention will be described with reference to the drawings.

図１は本発明に係る戸当りを備えたドア１０であり、ドア１０は丁番１３，１３等で壁１１に設けられたドア枠１２に取り付けられている。ドア１０の下端には一部破断して内部を示すように戸当りのドア側部材３０がドア１０に収納されて取り付けられている。２０は床面であり、２１は戸当りの台座である。台座２１は床面２０からわずかに突出しているが上面はフラットであり、磁石が吸引するように磁性体で構成されている。 FIG. 1 shows a door 10 having a door stop according to the present invention. The door 10 is attached to a door frame 12 provided on a wall 11 by hinges 13, 13 and the like. A door-side member 30 per door is housed and attached to the lower end of the door 10 so as to be partially broken and show the inside. 20 is a floor and 21 is a pedestal for a door. The pedestal 21 slightly protrudes from the floor surface 20, but the upper surface is flat and is made of a magnetic material so that the magnet attracts it.

図２は図１のＹ矢視図であり、台座２１はドア１０がほぼ全開した位置で床面２０に固定されている。矢印Ｘはドアの開扉方向を表している。 2 is a view taken in the direction of the arrow Y in FIG. 1, and the pedestal 21 is fixed to the floor 20 at a position where the door 10 is almost fully opened. Arrow X represents the door opening direction.

図３はドア１０の下端部の側面の断面図であり、本発明に係る戸当りのドア側部材３０が収納されている。ドア側部材３０は、主にケース３６に収納されたストッパー３１で構成され、ドア１０の下端に内蔵されて固定されている。ストッパー３１は、ケース３６に突設された回転軸３２に回動自在に取り付けられ、弾性体で構成され、磁石３５を内蔵している。磁石３５はストッパー３１がドア側部材３０に組み込まれた状態において床面２０に最も近い部分に埋め込まれている。３３はねじりコイルバネ等のバネ部材であり、ストッパー３１を矢印Ｐ方向へ付勢し、通常ではストッパー３１が床面２０に接触しないように保持している。３４は突部であり、ストッパー３１がそれ以上矢印Ｐ方向へ回動しないよう規制している。突部３４はネジ等で構成され、突部３４の長さを変えられるようにしてストッパー３１と床面２０との間隔を調整することができる。３７はスプリングであり、ストッパー３１を矢印Ｐ方向へ付勢している。ストッパー３１の形状は略三角形であり、回転軸３２を通す孔は三角形の一つの頂点の近くに設けられ、その頂点に対向する三角形の一辺に相当する下部側面Ｓ以外の２辺は長さが異なり、突部３４に当接する側面の長さは他の側面の長さより長くなるよう構成されている。 FIG. 3 is a cross-sectional view of the side surface of the lower end portion of the door 10, in which the door-side member 30 per door according to the present invention is housed. The door-side member 30 is mainly composed of a stopper 31 housed in the case 36 and is built in and fixed to the lower end of the door 10. The stopper 31 is rotatably attached to a rotary shaft 32 projecting from the case 36, is configured of an elastic body, and has a magnet 35 built therein. The magnet 35 is embedded in a portion closest to the floor surface 20 in a state where the stopper 31 is incorporated in the door side member 30. Reference numeral 33 denotes a spring member such as a torsion coil spring, which urges the stopper 31 in the direction of the arrow P and normally holds the stopper 31 so as not to contact the floor surface 20. Reference numeral 34 denotes a protrusion that restricts the stopper 31 from rotating further in the arrow P direction. The protrusion 34 is formed of a screw or the like, and the distance between the stopper 31 and the floor surface 20 can be adjusted so that the length of the protrusion 34 can be changed. Reference numeral 37 denotes a spring which urges the stopper 31 in the direction of arrow P. The shape of the stopper 31 is substantially triangular, and the hole through which the rotation shaft 32 passes is provided near one vertex of the triangle, and the length of the two sides other than the lower side surface S corresponding to one side of the triangle facing the vertex is long. Unlikely, the length of the side surface contacting the protrusion 34 is configured to be longer than the length of the other side surface.

台座２１は図５（ａ）に示すように、上面がフラットに形成された磁性体でできた板であり、ボルト２２，２２で床に固定されている。図５の（ｂ）は台座２１の別の実施例であり、上面に溝２３を施している。図５の（ｃ），（ｄ）は台座２１のさらに別の実施例であり、図５の（ｃ）は平面図、図５の（ｄ）は側面図であるが、台座２１の上面に山形２４を施したものである。溝２３および山形２４はいずれもストッパー３１と台座２１の摩擦力を増大させるのに有効である。 As shown in FIG. 5A, the pedestal 21 is a plate made of a magnetic material having a flat upper surface, and is fixed to the floor with bolts 22 and 22. FIG. 5B shows another embodiment of the pedestal 21 with a groove 23 on the upper surface. 5 (c) and 5 (d) show still another embodiment of the pedestal 21, FIG. 5 (c) is a plan view, and FIG. 5 (d) is a side view. Yamagata 24 is applied. Both the groove 23 and the chevron 24 are effective in increasing the frictional force between the stopper 31 and the pedestal 21.

以上のように構成された戸当りの動作を主に図３、図４を使って以下に説明する。図１、図２のように閉じられた状態のドア１０におけるドア側部材３０と床面２０の状態は図３で示すように、ストッパー３１はバネ部材３３の付勢力により突部３４に当接し、床面２０には接触していない。ドア１０を矢印Ｘで示す開扉方向に開扉していくと、ドア側部材３０は台座２１の上方に達することになる。この時の状態を図４（ａ）に示すが、台座２１は磁性体でできているので、磁石３５が磁力によって吸引され、ストッパー３１が回転軸３２の周りでバネ部材３３のバネ力に抗して矢印Ｑ方向へ回動し、わずかにストッパー３１の下部側面Ｓが台座２１の上面と接触する。ドア１０がさらに開扉方向へ移動すると、ストッパー３１は台座２１の上面の摩擦によりさらに回動され、スプリング３７のバネ力にも抗しながらストッパー３１がドア１０の下端と台座２１の間でくさびのようにはまり込み、それ以上回動できなくなり、図４（ｂ）に示した状態で止まる。すなわち、開扉方向への移動が規制されるのである。これは、台座２１の上面に接触する下部側面Ｓにおける回転軸３２から下部側面Ｓの長さがストッパー３１の回動とともに長くなるよう構成されているので、ドア１０の下端と台座２１の間の長さより長くなった時点で、ドア１０の下端と台座２１の間でくさびのような効果を発揮するからである。ドア１０を閉じるときはドア１０から手を離せばよく、ドア１０には図示しないドアクローザが通常設置されているので、その力によりドア側部材３０と台座２１の状態は図４（ｂ）から図４（ａ）へ移り、ドア１０は閉扉する。スプリング３７はこの時のドアクローザの働きを補助するためのものである。 The door-to-door operation configured as described above will be described below mainly with reference to FIGS. As shown in FIG. 3, the door side member 30 and the floor surface 20 in the closed door 10 as shown in FIGS. 1 and 2 are in contact with the protrusion 34 by the urging force of the spring member 33 as shown in FIG. The floor surface 20 is not in contact. When the door 10 is opened in the door opening direction indicated by the arrow X, the door-side member 30 reaches above the pedestal 21. FIG. 4A shows the state at this time. Since the pedestal 21 is made of a magnetic material, the magnet 35 is attracted by a magnetic force, and the stopper 31 resists the spring force of the spring member 33 around the rotation shaft 32. Then, it rotates in the direction of arrow Q, and the lower side surface S of the stopper 31 slightly contacts the upper surface of the base 21. When the door 10 further moves in the opening direction, the stopper 31 is further rotated by friction on the upper surface of the base 21, and the stopper 31 wedges between the lower end of the door 10 and the base 21 while resisting the spring force of the spring 37. It stops in the state shown in FIG. 4 (b). That is, movement in the door opening direction is restricted. This is because the length of the lower side surface S from the rotation shaft 32 on the lower side surface S that contacts the upper surface of the base 21 is increased with the rotation of the stopper 31, so that the distance between the lower end of the door 10 and the base 21 is increased. This is because a wedge-like effect is exhibited between the lower end of the door 10 and the pedestal 21 when it becomes longer than the length. When closing the door 10, it is sufficient to release the hand from the door 10, and since a door closer (not shown) is normally installed on the door 10, the state of the door side member 30 and the base 21 is shown in FIG. Moving to 4 (a), the door 10 is closed. The spring 37 is for assisting the function of the door closer at this time.

次に本発明の別の実施例について説明する。図６において、図３と同じものには同じ番号を付すが、戸当りのドア側部材５０はストッパー５１を有している。ストッパー５１は、ケース３６に突設された回転軸３２に回動自在に取り付けられ、磁石３５を内蔵しているが、材質は弾性体に限らず剛体でもよい。磁石３５はストッパー５１がドア側部材５０に組み込まれた状態において床面２０に最も近い部分に埋め込まれている。ストッパー５１の形状は、略二等辺三角形であり、二等辺三角形の底辺に相当する下部側面Ｔに垂直な方向に長孔５２が二等辺三角形の頂点に近い部分に設けられ、回転軸３２は長孔５２に通され、長孔５２に装着されたスプリング５３により回転軸３２とストッパー５１の下部側面Ｔ側は反発する方向に付勢されている。このように構成することにより、ストッパー５１が剛体であっても下部側面Ｔに垂直な方向に弾性を有する。回転軸３２から下部側面Ｔまでの距離は同じではなく、回転軸３２を通り下部側面Ｔの略中心の平面に垂直な線上の距離が一番長くなるよう（厳密には、前記平面の両端部分において一番長くなる）、下部側面Ｔの両端は丸みを持った曲面Ｒとして形成されている。５４はスプリング等のバネ部材であり、ストッパー５１を矢印Ｐ方向へ付勢し、通常ではストッパー５１が床面２０に接触しないように保持している。 Next, another embodiment of the present invention will be described. In FIG. 6, the same components as those in FIG. 3 are given the same numbers, but the door-side member 50 per door has a stopper 51. The stopper 51 is rotatably attached to a rotating shaft 32 projecting from the case 36 and incorporates a magnet 35, but the material is not limited to an elastic body but may be a rigid body. The magnet 35 is embedded in a portion closest to the floor surface 20 in a state where the stopper 51 is incorporated in the door side member 50. The shape of the stopper 51 is a substantially isosceles triangle, and a long hole 52 is provided in a portion near the apex of the isosceles triangle in a direction perpendicular to the lower side surface T corresponding to the base of the isosceles triangle. The rotary shaft 32 and the lower side surface T side of the stopper 51 are urged in a repulsive direction by a spring 53 that is passed through the hole 52 and attached to the long hole 52. With this configuration, even if the stopper 51 is a rigid body, it has elasticity in a direction perpendicular to the lower side surface T. The distance from the rotating shaft 32 to the lower side surface T is not the same, and the distance on the line passing through the rotating shaft 32 and perpendicular to the substantially central plane of the lower side surface T is the longest (strictly speaking, both end portions of the plane) The both ends of the lower side surface T are formed as rounded curved surfaces R. Reference numeral 54 denotes a spring member such as a spring which urges the stopper 51 in the direction of arrow P and normally holds the stopper 51 so as not to contact the floor surface 20.

以上のように構成された戸当りの動作を主に図６、図７を使って以下に説明する。図１、図２のように閉じられた状態のドア１０におけるドア側部材５０と床面２０の状態は図６で示すように、ストッパー５１がバネ部材５４の付勢力により突部３４に当接し、床面２０には接触していない。ドア１０を矢印Ｘで示す開扉方向に開扉していくと、ドア側部材５０は台座２１の上方に達することになる。この時の状態を図７（ａ）に示すが、台座２１は磁性体で構成されているので、磁石３５が磁力によって吸引され、ストッパー５１が回転軸３２の周りでバネ部材５４のバネ力に抗して矢印Ｑ方向へ回動し、わずかにストッパー５１の下部側面Ｔ（曲面Ｒ）が台座２１の上面と接触する。ドア１０がさらに開扉方向へ移動すると、ストッパー５１は台座２１の上面の摩擦によりさらに回動され、バネ部材５４のバネ力に抗しながらストッパー５１がドア１０の下端と台座２１の間でくさびのようにはまり込み、それ以上回動できなくなり、図７（ｂ）に示した状態で止まる。すなわち、開扉方向への移動が規制されるのである。これは、台座２１の上面に接触する下部側面Ｔにおける回転軸３２から下部側面Ｔの長さがストッパー５１の回動とともに長くなるよう構成されているので、ドア１０の下端と台座２１の間の長さより長くなった時点で、ドア１０の下端と台座２１の間でくさびのような効果を発揮するからである。ストッパー５１はスプリング５３によって弾性力が付与されており下部側面Ｔの中心部分は平面であるので、図示しない通常設置されているドアクローザの閉扉力とバネ部材５４のバネ力との間で力のバランスが取れ、図７（ｂ）の状態でドア１０を開放状態で安定に停止保持できる。ドア１０を閉じるときは、ドア１０を閉扉方向へ手で軽く押すと、上記バランスがくずれ、ドア側部材５０と台座２１の状態は図７（ｂ）から図７（ａ）へ移り、ドア１０は閉扉方向へ移動して閉まる。 The door-to-door operation configured as described above will be described below mainly with reference to FIGS. The state of the door side member 50 and the floor surface 20 in the door 10 in the closed state as shown in FIGS. 1 and 2 is such that the stopper 51 abuts against the protrusion 34 by the biasing force of the spring member 54 as shown in FIG. The floor surface 20 is not in contact. When the door 10 is opened in the door opening direction indicated by the arrow X, the door-side member 50 reaches above the pedestal 21. The state at this time is shown in FIG. 7A. Since the pedestal 21 is made of a magnetic material, the magnet 35 is attracted by the magnetic force, and the stopper 51 is moved to the spring force of the spring member 54 around the rotation shaft 32. Against the rotation in the direction of arrow Q, the lower side surface T (curved surface R) of the stopper 51 slightly contacts the upper surface of the base 21. When the door 10 further moves in the opening direction, the stopper 51 is further rotated by friction on the upper surface of the base 21, and the stopper 51 wedges between the lower end of the door 10 and the base 21 while resisting the spring force of the spring member 54. It stops in the state shown in FIG. 7 (b). That is, movement in the door opening direction is restricted. This is because the length of the lower side surface T from the rotating shaft 32 on the lower side surface T contacting the upper surface of the base 21 is increased with the rotation of the stopper 51, so that the distance between the lower end of the door 10 and the base 21 is increased. This is because a wedge-like effect is exhibited between the lower end of the door 10 and the pedestal 21 when it becomes longer than the length. Since the stopper 51 is given an elastic force by a spring 53 and the central portion of the lower side surface T is a flat surface, the force balance between the closing force of a normally installed door closer not shown and the spring force of the spring member 54 is not shown. The door 10 can be stably stopped and held in the opened state in the state of FIG. When the door 10 is closed, if the door 10 is lightly pushed in the closing direction by hand, the balance is lost, and the state of the door side member 50 and the pedestal 21 moves from FIG. 7B to FIG. Moves in the closing direction and closes.

本発明による戸当りは、上述した実施の形態に限定されず、特許請求の範囲に記載した範囲で種々の変形や改良が可能である。例えば、上記の説明では、ストッパー５１は下部側面Ｔの両端が曲面Ｒとして形成されているとしたが、本発明において効果を発揮するのは磁石３５に近い曲面Ｒであり、下部側面Ｔの両端の少なくとも一方に曲面Ｒが形成されていればよい。 The door stop according to the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made within the scope described in the claims. For example, in the above description, the stopper 51 is formed such that both ends of the lower side surface T are curved surfaces R. However, the curved surface R close to the magnet 35 is effective in the present invention, and both ends of the lower side surface T are effective. The curved surface R should just be formed in at least one of these.
