Description

本発明は扉開閉構造に関し、より詳しくは、建造物や家具、置物などに取り付けられた回動自在に開閉する扉の開閉構造に関する。   The present invention relates to a door opening / closing structure, and more particularly, to a door opening / closing structure attached to a building, furniture, a figurine or the like, which opens and closes freely.

回動自在に開閉する扉は建造物や家具、置物などに広く用いられており、そのような扉の開閉構造の多くは、軸部材（凸部）と軸受け（凹部）とを回動自在に凹凸係合固定したものである。特許文献１の扉開閉構造も、扉の回動中心の扉側と扉の取付け対象である本体側とに軸受けを設け、両方の軸受けに軸部材を回動自在に凹凸係合したものである。しかし、これら従来の扉開閉構造は扉の着脱を想定していないため、扉を本体から外そうとすれば、軸部材と軸受けの凹凸が障害となって着脱が容易でない。   Doors that can be freely opened and closed are widely used in buildings, furniture, figurines, and the like. Many of such door opening and closing structures can freely rotate a shaft member (convex part) and a bearing (concave part). Concave and convex engagement fixed. The door opening / closing structure of Patent Document 1 also has bearings provided on the door side at the center of rotation of the door and the main body side to which the door is attached, and the shaft member is pivotally engaged with both bearings so as to be rotatable. . However, since these conventional door opening / closing structures do not assume the attachment / detachment of the door, if the door is to be removed from the main body, the unevenness of the shaft member and the bearing becomes an obstacle, and the attachment / detachment is not easy.

また、特許文献２には、ヒンジ軸（凸部）と係合孔（凹部）による凹凸係合固定を基本構成としながら、ヒンジ軸を上下に移動できるように構成し、ヒンジ軸が係合孔に近づくと、ヒンジ軸と係合孔の両方に設けた磁石の吸引力でヒンジ軸が飛び出し、ヒンジ軸と係合孔による凹凸係合固定がなされるヒンジが提案されている。しかし、このヒンジも、凹凸係合によって扉をその取付け対象体に固定する技術であり、扉を本体から外そうとすれば、凹凸係合固定を解除する別の手段を必要とし、扉の着脱は容易でない。   Patent Document 2 is configured so that the hinge shaft can be moved up and down while the concave and convex engagement fixing by the hinge shaft (convex portion) and the engagement hole (concave portion) is a basic configuration, and the hinge shaft is the engagement hole. As the hinge approaches, the hinge shaft pops out by the attractive force of the magnets provided on both the hinge shaft and the engagement hole, and a hinge is proposed in which the concave and convex engagement is fixed by the hinge shaft and the engagement hole. However, this hinge is also a technology for fixing the door to the mounting object by uneven engagement, and if it is intended to remove the door from the main body, another means for releasing the uneven engagement fixation is required, and the door can be attached and detached. Is not easy.

実用新案登録第３１６００３５号公報Utility Model Registration No. 3160035 特開２００２−２１４１１号公報JP 2002-21411 A

本発明は、上記従来の問題に鑑みてなされたものであり、磁石の吸引力によって扉の取付け対象体に固定された回動式開閉扉において、扉の着脱が容易な扉開閉構造を提供することを目的とする。   The present invention has been made in view of the above-described conventional problems, and provides a door opening / closing structure in which a door can be easily attached and detached in a rotary opening / closing door fixed to a door attachment target body by a magnetic attraction force. For the purpose.

本発明の扉開閉構造は、回動自在に固定された扉の少なくとも１箇所において、扉側に取り付けられた第１軸部材と扉の取付け対象体側に取り付けられた第２軸部材とが対向するように配置され、前記第１軸部材および前記第２軸部材の一方が磁石からなり、他方が磁性体または該磁石と吸引しあう磁石からなり、前記第１軸部材および前記第２軸部材の対向面がともに平滑面であり、前記第１軸部材および前記第２軸部材のうち少なくとも一方が、軸方向に沿って移動するように前記扉または前記取付け対象体に取り付けられ、前記扉が、磁石の吸引力によって、前記第１軸部材および前記第２軸部材の対向面が、前記第１軸部材および前記第２軸部材の取付け面から突出した状態で、前記取付け対象体に回動自在に固定され、前記扉と前記取付け対象体とが固定された状態で、磁石の吸引力に抗して前記取付け対象体から着脱可能に構成されてなることを特徴としている。 In the door opening / closing structure of the present invention, the first shaft member attached to the door side and the second shaft member attached to the attachment target body side of the door face each other in at least one position of the door fixed rotatably. One of the first shaft member and the second shaft member is made of a magnet, and the other is made of a magnetic body or a magnet that attracts the magnet, and the first shaft member and the second shaft member Both opposing surfaces are smooth surfaces, and at least one of the first shaft member and the second shaft member is attached to the door or the attachment target body so as to move along the axial direction , The mounting surface of the first shaft member and the second shaft member can be rotated to the mounting target body in a state where the opposing surfaces of the first shaft member and the second shaft member protrude from the mounting surfaces of the first shaft member and the second shaft member by the magnet's attractive force. Fixed to the door and front In a state where a mounting object which is fixed, is characterized in that against the suction force of the magnet formed by detachably attached from the mounting target member.

本発明の扉開閉構造は、両端で回動自在に固定された扉の少なくとも一端において、扉側に取り付けられた第１軸部材と扉の取付け対象体側に取り付けられた第２軸部材とが対向するように配置され、前記第１軸部材および前記第２軸部材の一方が磁石からなり、他方が磁性体または該磁石と吸引しあう磁石からなり、前記第１軸部材および前記第２軸部材の対向面がともに平滑面であり、前記第１軸部材および前記第２軸部材のうち少なくとも一方が、軸方向に沿って移動するように前記扉または前記取付け対象体に取り付けられ、前記扉が、磁石の吸引力によって、前記第１軸部材および前記第２軸部材の対向面が、前記第１軸部材および前記第２軸部材の取付け面から突出した状態で、前記取付け対象体に回動自在に固定され、前記扉と前記取付け対象体とが固定された状態で、磁石の吸引力に抗して前記取付け対象体から着脱可能に構成されてなることを特徴としている。 In the door opening / closing structure of the present invention, at least one end of the door fixed to be rotatable at both ends, the first shaft member attached to the door side and the second shaft member attached to the door mounting object side face each other. One of the first shaft member and the second shaft member is made of a magnet, and the other is made of a magnetic body or a magnet that attracts the magnet, and the first shaft member and the second shaft member The opposing surfaces are both smooth surfaces, and at least one of the first shaft member and the second shaft member is attached to the door or the attachment target body so as to move along the axial direction. The opposing surface of the first shaft member and the second shaft member is rotated by the attachment target body in a state where the opposing surfaces of the first shaft member and the second shaft member protrude from the mounting surfaces of the first shaft member and the second shaft member. The door is fixed freely Wherein in a state where the mounting object is fixed, it is characterized in that against the suction force of the magnet formed by detachably attached from the mounting target member.

また、前記扉または前記取付け対象体に、前記移動するように取り付けられた軸部材を磁石の吸引方向と逆の方向に付勢する弾性体を備えることが好ましい。   Moreover, it is preferable to provide the elastic member which urges | biases the shaft member attached to the said door or the said attachment object body in the direction opposite to the magnet's attraction | suction direction.

また、前記２つの軸部材の対向面の少なくとも一方に、滑材が設けられてなることが好ましい。   Moreover, it is preferable that a lubricant is provided on at least one of the opposing surfaces of the two shaft members.

本発明は、扉とその取付け対象体との固定を、凹凸係合固定ではなく、磁石の吸引力によって行うことができ、好ましくは磁石の吸引力のみによって行うことができる。そのため、扉とその取付け対象体とが磁石の吸引力によって固定された状態で、磁石の吸引力に抗して扉を容易に取り外すことができ、扉の着脱が容易である。これによって、購入者自身が、室内デザインや好みに応じて異なる意匠を有する扉に容易に交換することができる。また、扉を異なる意匠のものに交換することができるため、意匠ごとに扉を製造する必要がなく、製造販売業者は在庫点数を減らすことができ、在庫管理が容易となり、コストも低減できる。さらに、扉を交換するだけで多様な意匠を取り入れることができるので、意匠の選択肢を大幅に増やすことができる。さらに、扉が破損してもその交換が容易であるため、修復の際のコスト負担を軽減できる。   In the present invention, the door and its attachment object can be fixed not by the concave and convex engagement fixing but by the magnet attractive force, and preferably only by the magnet attractive force. Therefore, the door can be easily detached against the magnet's attractive force in a state where the door and the attachment target body are fixed by the magnet's attractive force, and the door can be easily attached and detached. Thus, the purchaser can easily replace the door with a door having a different design according to the room design or preference. Moreover, since the door can be exchanged for a different design, it is not necessary to manufacture the door for each design, and the manufacturer / seller can reduce the number of stocks, facilitate inventory management, and reduce costs. Furthermore, since various designs can be taken in just by replacing the doors, design options can be greatly increased. Furthermore, even if the door is broken, it is easy to replace it, so that the cost burden during repair can be reduced.

また、軸部材を、軸方向に沿って移動するように扉または取付け対象体に取り付けたものは、扉とその取付け対象体との間に空隙が形成され、対向する軸部材同士の間に空隙が形成される場合でも、その空隙に応じて、移動可能な軸部材が磁石の吸引力によって対向する軸部材に接近し、好ましくは移動可能な軸部材が取付け面から突出する。そのため、寸法精度の異なる構造体に対しても、磁石の吸引力による扉と取付け対象体との回動固定を確実に行うことができる。これによって、扉とその取付け対象体との間に、ある程度の空隙を有する家具などに対して、高い寸法精度を要求することなく磁石の吸引力による回動固定構造を容易に適用することができる。なお、この可動軸部材は、凹凸係合固定の係合と解除のために軸方向に沿って移動するものではなく、磁石の吸引力による回動固定を行うためのものである点で、従来の軸部材と明確に異なる。さらにいえば、扉とその取付け対象体とが固定された状態（軸部材が磁石の吸引力により引き出され、軸部材の取付け面から突出した状態）で、磁石の吸引力に抗して、扉をその取付け対象体から取り外すことができる点で、従来の凹凸係合固定を前提として移動自在に構成された軸部材とは作用が本質的に異なる。   In addition, when the shaft member is attached to the door or the mounting target body so as to move along the axial direction, a gap is formed between the door and the mounting target body, and a gap is formed between the opposing shaft members. Even in the case where is formed, the movable shaft member approaches the opposite shaft member by the attractive force of the magnet according to the gap, and preferably the movable shaft member protrudes from the mounting surface. Therefore, even for structures having different dimensional accuracy, it is possible to reliably rotate and fix the door and the object to be attached by the attractive force of the magnet. Thereby, it is possible to easily apply the rotation fixing structure by the attractive force of the magnet to the furniture having a certain gap between the door and the mounting target body without requiring high dimensional accuracy. . In addition, this movable shaft member does not move along the axial direction for engaging and releasing the concave and convex engagement fixing, but is used for rotationally fixing by the attractive force of the magnet. It is clearly different from the shaft member. Furthermore, in a state where the door and its mounting target are fixed (the shaft member is pulled out by the magnet's attractive force and protrudes from the mounting surface of the shaft member), the door resists the magnet's attractive force. Is essentially different from the conventional shaft member configured to be movable on the premise of concavo-convex engagement and fixation.

さらに、磁石の吸引方向と逆の方向に付勢する弾性体を可動軸部材に取り付けたものは、扉とその取付け対象体とを固定していない状態では、可動軸部材は弾性体によってその取付け面側に付勢され、好ましくは軸部材の取付け面から突出しない方向に付勢されているため、扉の取付け時に軸部材は邪魔にならない。一方、扉を取付け対象体に固定するときには、軸部材は、弾性体の付勢力に抗する磁石の吸引力によって、対向する軸部材側に移動し、好ましくは軸部材の取付け面から突出するので、磁石の吸引力による扉と取付け対象体との回動固定を容易かつ確実に行うことができる。   Further, in the case where an elastic body that is biased in the direction opposite to the magnet attracting direction is attached to the movable shaft member, the movable shaft member is attached to the movable shaft member by the elastic body in a state where the door and the attachment target body are not fixed. The shaft member is biased to the surface side, and preferably biased in a direction that does not protrude from the mounting surface of the shaft member, so that the shaft member does not get in the way when the door is mounted. On the other hand, when the door is fixed to the attachment target body, the shaft member moves to the opposite shaft member side and preferably protrudes from the mounting surface of the shaft member by the attractive force of the magnet against the urging force of the elastic body. In addition, it is possible to easily and reliably perform the rotation and fixing between the door and the attachment target body by the attractive force of the magnet.

さらに、扉側の軸部材と対象体側の軸部材の対向面に滑材を設けたものは、扉側の軸部材と対象体側の軸部材との摩擦抵抗が低減され、扉の回動および着脱がしやすい。   In addition, when a sliding member is provided on the opposing surface of the door-side shaft member and the object-side shaft member, the frictional resistance between the door-side shaft member and the object-side shaft member is reduced, and the door can be rotated and attached. Easy to remove.

本発明の実施の形態による扉開閉構造について、添付図面に沿って詳細に説明する。   A door opening and closing structure according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

図１は、本発明の扉開閉構造に係る家具の概略斜視図であり、図２は、図１の家具に備えられた本発明の第１の実施の形態による扉開閉構造の概略断面図であり、図３は、図２に対応する図であって、扉の取付け前の状態における扉の取付け対象体を示した概略断面図である。   FIG. 1 is a schematic perspective view of the furniture according to the door opening / closing structure of the present invention, and FIG. 2 is a schematic cross-sectional view of the door opening / closing structure according to the first embodiment of the present invention provided in the furniture of FIG. FIG. 3 is a diagram corresponding to FIG. 2, and is a schematic cross-sectional view showing a door attachment target body in a state before the door is attached.

図１に示されるように、第１の実施の形態による扉開閉構造を備える家具Ａは、天板５と地板６を有し、三方の側面が覆われ、前面のほぼ全面が開口した箱形状を有する木製の構造体である。家具Ａの前面の両側には、開口を観音開き式に開閉する左右１対の扉１ａ，１ｂが取り付けられている。２枚の扉１ａ，１ｂは木製の長方形板状体である。扉１ａ，１ｂの一端は、家具Ａの前面の開口端より前方で、その上下が天板５および地板６に回動自在に固定されている。   As shown in FIG. 1, the furniture A having the door opening / closing structure according to the first embodiment has a top plate 5 and a base plate 6, is covered in three sides, and has a box shape in which almost the entire front surface is opened. A wooden structure having On both sides of the front surface of the furniture A, a pair of left and right doors 1a and 1b for opening and closing the opening in a double door manner is attached. The two doors 1a and 1b are wooden rectangular plates. One end of the doors 1a and 1b is forward of the opening end of the front surface of the furniture A, and the upper and lower sides thereof are fixed to the top plate 5 and the base plate 6 so as to be rotatable.

図２に示されるように、扉１ａの取付け対象体側の部材である天板５の下面には、円柱形状の軸部材（以下、第１軸部材という）１０ａが、天板５の下面に形成された凹部１２に埋設されており、その下端が天板５の下面から下方に突出している。一方、扉１ａの上端には、第１軸部材１０ａと対向する位置に円柱形状の軸部材（以下、第２軸部材という）１０ｂが扉１ａの上面とほぼ面一でわずかに突出するように埋込み固定されている。   As shown in FIG. 2, a columnar shaft member (hereinafter referred to as a first shaft member) 10 a is formed on the lower surface of the top plate 5 on the lower surface of the top plate 5, which is a member on the attachment target body side of the door 1 a. The lower end of the recessed portion 12 protrudes downward from the lower surface of the top plate 5. On the other hand, at the upper end of the door 1a, a cylindrical shaft member (hereinafter referred to as a second shaft member) 10b protrudes slightly flush with the upper surface of the door 1a at a position facing the first shaft member 10a. Embedded and fixed.

第１軸部材１０ａは鉄製であり、第２軸部材１０ｂは磁石からなる。これによって、第１軸部材１０ａは第２軸部材１０ｂに吸引され、その磁石の吸引力で、扉１ａは天板５に回動自在に固定される。なお、第１軸部材は鉄製に限定されず、磁性体やマルテンサイト系ステンレス鋼などの強磁性体にすることができる。磁石の種類も特に限定されるものではないが、取扱いが容易なフェライト磁石やネオジム磁石などの永久磁石を用いることが好ましい。   The first shaft member 10a is made of iron, and the second shaft member 10b is made of a magnet. Thus, the first shaft member 10a is attracted to the second shaft member 10b, and the door 1a is rotatably fixed to the top plate 5 by the attraction force of the magnet. The first shaft member is not limited to iron, and can be a ferromagnetic material such as a magnetic material or martensitic stainless steel. The type of magnet is not particularly limited, but it is preferable to use a permanent magnet such as a ferrite magnet or a neodymium magnet that is easy to handle.

また、第１軸部材１０ａは、弾性体であるバネ１５を介して天板５に取り付けられている。そのため、第１軸部材１０ａは、バネ１５の伸縮範囲内で、軸方向に沿って移動自在となり、凹部１２内を摺動する。バネ１５は、第１軸部材１０ａを、磁石の吸引方向と逆の方向、すなわち第１軸部材１０ａが天板５の下面から突出しない方向である天板５側に付勢するものである。これによって、第１軸部材１０ａは、図３に示されるように、扉１ａの固定前には、その下端が天板５の下面から突出せず、天板５の下面とほぼ面一であるため邪魔にならない一方で、扉１ａを家具Ａに固定するときには、図２に示されるように、バネ１５の付勢力に抗する磁石の吸引力によって、対向する第２軸部材１０ｂの方に移動し、第２軸部材１０ｂに当接する。その結果、扉１ａと家具Ａとの間に空隙が形成されている場合でも、第１軸部材１０ａと第２軸部材１０ｂの間隔の分だけ第１軸部材１０ａが移動し、回動固定を確実に行うことができる。弾性体はバネに限定されるものではなく、ゴムやスポンジ等とすることができる。なお、第２軸部材の固定は嵌合やピン、ネジ、接着剤等によって行う。   The first shaft member 10a is attached to the top plate 5 via a spring 15 that is an elastic body. Therefore, the first shaft member 10 a is movable along the axial direction within the expansion / contraction range of the spring 15 and slides in the recess 12. The spring 15 biases the first shaft member 10 a toward the top plate 5, which is the direction opposite to the magnet attracting direction, that is, the direction in which the first shaft member 10 a does not protrude from the lower surface of the top plate 5. Accordingly, as shown in FIG. 3, the lower end of the first shaft member 10 a does not protrude from the lower surface of the top plate 5 and is substantially flush with the lower surface of the top plate 5 before the door 1 a is fixed. Therefore, when the door 1a is fixed to the furniture A on the other hand, it moves toward the opposing second shaft member 10b by the attractive force of the magnet against the urging force of the spring 15, as shown in FIG. And abuts against the second shaft member 10b. As a result, even when a gap is formed between the door 1a and the furniture A, the first shaft member 10a moves by the distance between the first shaft member 10a and the second shaft member 10b, and the rotation is fixed. It can be done reliably. The elastic body is not limited to a spring, and may be rubber, sponge, or the like. The second shaft member is fixed by fitting, pins, screws, adhesives, or the like.

第１軸部材１０ａの下端面と第２軸部材１０ｂの上端面、すなわち軸部材の対向面は、ともに平面であり、凹部が形成されていない。天板５の下面と扉１ａの上面も平面であり、扉１ａを凹凸係合固定するための凹凸は形成されていない。また、上述した対向面は平滑面であり、これによって、軸部材同士の対向面の接触による摩擦抵抗が低減され、扉１ａの回動および扉１ａの家具Ａからの着脱がしやすい。   Both the lower end surface of the first shaft member 10a and the upper end surface of the second shaft member 10b, that is, the opposing surface of the shaft member are flat surfaces, and no recess is formed. The lower surface of the top plate 5 and the upper surface of the door 1a are also flat, and no unevenness for fixing the unevenness of the door 1a is formed. Further, the above-described facing surface is a smooth surface, whereby frictional resistance due to contact between the facing surfaces of the shaft members is reduced, and the door 1a can be easily rotated and detached from the furniture A.

一方、扉１ａの下端の回動固定は公知の軸受けによりなされているが、上述した扉１ａの上端におけるものと同じ構成にすることができる。なお、扉１ｂにおける扉開閉構造の構成も扉１ａにおけるものと基本的に同じなので、説明は繰り返さない。   On the other hand, although the rotation of the lower end of the door 1a is fixed by a known bearing, the same configuration as that at the upper end of the door 1a described above can be used. Since the door opening / closing structure of door 1b is basically the same as that of door 1a, description thereof will not be repeated.

図４は、本発明の第２の実施の形態による扉開閉構造の概略断面図であり、図５は、図４に対応する図であって、扉の取付け前の状態における扉の取付け対象体を示した概略断面図である。本実施の形態による扉開閉構造の構成は先に説明した第１の実施の形態によるものと基本的に同じなので、相違点を中心に説明する。   FIG. 4 is a schematic cross-sectional view of a door opening / closing structure according to a second embodiment of the present invention, and FIG. 5 is a view corresponding to FIG. 4 and is a door attachment target in a state before the door is attached. It is the schematic sectional drawing which showed. Since the configuration of the door opening and closing structure according to the present embodiment is basically the same as that according to the first embodiment described above, the differences will be mainly described.

図４および５に示されるように、第２の実施の形態による扉１ａは、第１軸部材１０ａの上側に外周全体にわたって鍔２０が形成されており、第１軸部材１０ａが縦断面でＴ字形状を有する点、および天板５の下面に形成された凹部に、ケーシング１６が埋込み固定され、このケーシング１６の中に圧縮バネ１５と第１軸部材１０ａとが収容されている点が第１の実施の形態によるものと異なる。   As shown in FIGS. 4 and 5, the door 1a according to the second embodiment has a flange 20 formed over the entire outer periphery on the upper side of the first shaft member 10a, and the first shaft member 10a has a longitudinal section T. A casing 16 is embedded and fixed in a concave portion formed on the lower surface of the top plate 5 and a point having a letter shape, and the compression spring 15 and the first shaft member 10 a are accommodated in the casing 16. Different from that of the first embodiment.

ケーシング１６は、円筒形状を有する部材であり、中空部に第１軸部材１０ａとバネ１５を収容する。ケーシング１６の下面には、周全体にわたって中心に向かって延びる縁２１が形成されており、縁２１の内側に、軸部材１０ａの本体外周よりも広く、軸部材１０ａの鍔２０の外周よりも狭い径を有する開口が形成されている。このケーシング１６内は、図４に示されるように、縁２１上にバネ１５を載置し、さらに第１軸部材１０ａの下端を、バネ１５を介してケーシング１６下面の開口に挿通し、バネ１５が、第１軸部材１０ａの鍔２０とケーシング１６の縁２１とに挟まれるよう構成されている。そして、このように構成されたケーシング１６は、その前記開口側が天板５の下面に位置するように天板５の凹部に埋込み固定される。このように構成することによっても、第１軸部材１０ａは、バネ１５によって、磁石の吸引方向と逆の方向、すなわち第１軸部材１０ａが天板５の下面から突出しない方向に付勢される。これによって、第１軸部材１０ａは、図５に示されるように、扉１ａの固定前には、第１軸部材１０ａの下端が天板５の下面から突出せず、天板５の下面とほぼ面一であるため邪魔にならない一方で、扉１ａを家具Ａに固定するときには、図４に示されるように、バネ１５の付勢力に抗する磁石の吸引力によって、対向する第２軸部材１０ｂの方に移動し、第２軸部材１０ｂに当接する。その結果、扉１ａと家具Ａとの間に空隙が形成されている場合でも、第１軸部材１０ａと第２軸部材１０ｂの間隔の分だけ第１軸部材１０ａが移動し、回動固定を確実に行うことができる。なお、ケーシング１６の材質は特に限定されるものではなく、非磁性の金属や合成樹脂、木材を用いることができる。   The casing 16 is a member having a cylindrical shape, and houses the first shaft member 10a and the spring 15 in the hollow portion. An edge 21 extending toward the center over the entire circumference is formed on the lower surface of the casing 16, and the inner side of the edge 21 is wider than the outer periphery of the main body of the shaft member 10 a and narrower than the outer periphery of the flange 20 of the shaft member 10 a. An opening having a diameter is formed. In this casing 16, as shown in FIG. 4, a spring 15 is placed on the edge 21, and the lower end of the first shaft member 10 a is inserted through the opening on the lower surface of the casing 16 via the spring 15. 15 is configured to be sandwiched between the flange 20 of the first shaft member 10 a and the edge 21 of the casing 16. The casing 16 configured as described above is embedded and fixed in the recess of the top plate 5 so that the opening side is located on the lower surface of the top plate 5. Also with this configuration, the first shaft member 10 a is urged by the spring 15 in the direction opposite to the magnet attracting direction, that is, the direction in which the first shaft member 10 a does not protrude from the lower surface of the top plate 5. . Accordingly, as shown in FIG. 5, the first shaft member 10 a has a lower end of the first shaft member 10 a that does not protrude from the lower surface of the top plate 5 before the door 1 a is fixed. While it is substantially flat and does not interfere, when the door 1 a is fixed to the furniture A, as shown in FIG. 4, the opposing second shaft member is attracted by the attractive force of the magnet against the urging force of the spring 15. It moves toward 10b and contacts the second shaft member 10b. As a result, even when a gap is formed between the door 1a and the furniture A, the first shaft member 10a moves by the distance between the first shaft member 10a and the second shaft member 10b, and the rotation is fixed. It can be done reliably. The material of the casing 16 is not particularly limited, and nonmagnetic metal, synthetic resin, or wood can be used.

以上のように、本発明の上記実施の形態による扉開閉構造によれば、扉とその取付け対象体との固定を、磁石の吸引力によって行うことができるため、扉とその取付け対象体とが磁石の吸引力によって固定された状態で、磁石の吸引力に抗して扉を容易に取り外すことができ、扉の着脱が容易である。また、一方の軸部材は軸方向に沿って移動自在に構成されているので、扉とその取付け対象体との間に空隙が形成されている場合でも、その空隙の距離に応じて、一方の軸部材が、対向する他方の軸部材に磁石の吸引力により接近し当接することができる。その結果、家具などのように扉と本体との間にある程度の空隙が形成されているものでも、本発明の磁石の吸引力による回動固定の構造を適用することができ、寸法精度の異なる構造体に対しても扉と取付け対象体との回動固定を確実に行うことができる。さらに、磁石の吸引方向と逆の方向に付勢する弾性体を取り付けることにより、扉とその取付け対象体とを固定していない状態では、軸部材はその取付け面から突出しない方向に弾性体によって付勢されているため、邪魔にならない一方、扉とその取付け対象体とを固定するときには、軸部材は、弾性体の付勢力に抗する磁石の吸引力によって、対向する他方の軸部材側に移動し、当接する。その結果、扉と取付け対象体との回動固定を容易かつ確実に行うことができる。   As described above, according to the door opening / closing structure according to the above-described embodiment of the present invention, the door and the attachment target body can be fixed by the attractive force of the magnet. The door can be easily removed against the magnet's attractive force while being fixed by the magnet's attractive force, and the door can be easily attached and detached. In addition, since one shaft member is configured to be movable along the axial direction, even if a gap is formed between the door and the mounting target body, one of the shaft members is in accordance with the distance of the gap. The shaft member can approach and come into contact with the other opposite shaft member by the attractive force of the magnet. As a result, even if a certain amount of space is formed between the door and the main body, such as furniture, the structure of rotation fixing by the attractive force of the magnet of the present invention can be applied, and the dimensional accuracy is different. Also with respect to the structure, the door and the mounting target body can be securely fixed. Furthermore, by attaching an elastic body that urges the magnet in the direction opposite to the magnet attracting direction, the shaft member is moved by the elastic body in a direction that does not protrude from the mounting surface when the door and the mounting target body are not fixed. Because it is biased, it does not get in the way, but when fixing the door and its mounting object, the shaft member is moved toward the other shaft member facing by the attractive force of the magnet against the biasing force of the elastic body. Move and abut. As a result, the rotation of the door and the attachment target body can be easily and reliably fixed.
