Description

本発明は、家屋等に配設された扉体の開閉に際して、当該扉体を自動的に、且つ、静粛に閉止させるための扉体閉止装置に関するものである。   The present invention relates to a door body closing device for automatically and quietly closing a door body disposed in a house or the like when the door body is opened or closed.

家屋等の開口口を区画する枠体に対して回転可能に配設された扉体を、当該扉体の閉止直前に減速して静かに閉止させるようにした扉体閉止装置は、従来から存在する（特許文献１）。
このような扉体閉止装置１００は、図８に示すように、扉体Ａに取り付けられる装置本体１０１と、家屋等の開口口を区画する枠体のうちの上枠体Ｂに取り付けられるブラケット１０２とで構成され、装置本体１０１は、扉体Ａの裏面上方で、ヒンジ１０３が取着された側端に近いところに取り付けられ、また、ブラケット１０２は、装置本体１０１が取り付けられた位置に対応して、上枠体Ｂの、ヒンジ１０３が取着された縦枠体Ｃの方に近いところに取り付けられている。
そして、本扉体閉止装置１００においては、装置本体１０１のアーム１０４のアーム本体１０５に設けられたガイド溝１０５ａにブラケット１０２のピン１０２ａが係合する前においては、図９（Ａ）に示すように、アーム１０４の支持部１０６に設けられた突条部１０６ａには、スプリング１０７により付勢されたスライダ１０８の突起１０８ａが当接しており、このためアーム１０４は、同図中の矢印で示す反時計回り方向のモーメントを受ける一方、その支持部１０６の円弧状縦板１０６ｂの側縁端が、緩衝機構１１０が取り付けられるケース体１０９のボス（図示せず）あるいは緩衝機構１１０のフランジ１１０ａに当接し、当該ストッパ壁から時計回り方向のモーメントを受ける。したがって、アーム１０４は、同図に示すようなブラケット１０２のピン１０２ａとの係合が可能な所定閉成角に適応した角度位置に保持されることになる。更に、扉体Ａを同図中の矢印方向に閉成して行くと、アーム１０４のガイド溝１０５ａにブラケット１０２のピン１０２ａが係合するべく同図に示すようなガイド溝１０５ａの開口口がピン１０２ａの位置に達する状態となる。 Conventionally, there is a door body closing device in which a door body that is rotatably arranged with respect to a frame body that defines an opening of a house, etc., is decelerated immediately before closing the door body to quietly close the door body. (Patent Document 1).
As shown in FIG. 8, such a door body closing device 100 includes an apparatus main body 101 attached to the door body A, and a bracket 102 attached to an upper frame body B among the frame bodies that define an opening of a house or the like. The apparatus main body 101 is attached near the side end where the hinge 103 is attached above the back surface of the door body A, and the bracket 102 corresponds to the position where the apparatus main body 101 is attached. The upper frame B is attached to a position closer to the vertical frame C to which the hinge 103 is attached.
In the door closing device 100, before the pin 102a of the bracket 102 is engaged with the guide groove 105a provided in the arm body 105 of the arm 104 of the device body 101, as shown in FIG. Further, the protrusion 108a of the slider 108 urged by the spring 107 is in contact with the protrusion 106a provided on the support portion 106 of the arm 104. Therefore, the arm 104 is indicated by an arrow in FIG. While receiving the moment in the counterclockwise direction, the side edge of the arcuate vertical plate 106b of the support portion 106 is attached to the boss (not shown) of the case body 109 to which the buffer mechanism 110 is attached or the flange 110a of the buffer mechanism 110. It abuts and receives a clockwise moment from the stopper wall. Therefore, the arm 104 is held at an angular position adapted to a predetermined closing angle capable of engaging with the pin 102a of the bracket 102 as shown in FIG. Further, when the door body A is closed in the direction of the arrow in the figure, the opening of the guide groove 105a as shown in the figure is provided so that the pin 102a of the bracket 102 is engaged with the guide groove 105a of the arm 104. The state reaches the position of the pin 102a.

ガイド溝１０５ａにピン１０２ａが係合した後は、扉体Ａの、図９（Ｂ）中の矢印方向の閉成に従ってピン１０２ａがガイド溝１０５ａに沿う態様で相対移動し始めると、アーム１０４が同図中の矢印で示す時計回り方向に回転し始めると同時に、アーム１０４の突条部１０６ａに対するスライダ１０８の当接部位が、その突起１０８ａ位置からその閉塞端面位置に変わるため、アーム１０４は、同図中の矢印で示す時計回り方向のモーメントを受ける。かかるモーメントを受けてアーム１０４が回転し始めるとともに扉体Ａが同図の矢印方向に自動的に回転して行き、図９（Ｃ）のように閉止される。しかるに、上述したアーム１０４の回転に際しては、この回転速度がアーム１０４の回転軸に作用する緩衝機構１１０により減速されるので、扉体Ａの閉成に際し当該扉体Ａの回転も減速されて緩やかになる。このため、扉体Ａが戸当り（図示せず）に勢いよく衝突して衝撃音などが発せられる不具合を生ずることもなく静粛に閉止される。
尚、扉体Ａの閉成後に、当該扉体Ａを図９（Ｃ）中の矢印方向に開成して行くと、ブラケット１０２のピン１０２ａがアーム１０４のガイド溝１０５ａに沿って相対移動する一方、アーム１０４は、スプリング１０７の付勢力に抗しつつ同図中の矢印で示す反時計回り方向に回転して行き、図９（Ａ）に示す状態になったところで当該アーム１０４のガイド溝１０５ａとブラケット１０２のピン１０２ａとの係合が外れるが、この外れた位置で上述のようにして所定閉成角に適応した角度位置に保持される。 After the pin 102a is engaged with the guide groove 105a, when the pin 102a starts to move relative to the door body A in the direction of the arrow in FIG. At the same time as starting to rotate in the clockwise direction indicated by the arrow in the figure, the contact portion of the slider 108 with respect to the ridge 106a of the arm 104 changes from the position of the protrusion 108a to the position of the closed end surface, so the arm 104 It receives a moment in the clockwise direction indicated by the arrow in the figure. In response to this moment, the arm 104 starts to rotate and the door body A automatically rotates in the direction of the arrow in the figure, and is closed as shown in FIG. However, when the arm 104 is rotated, the rotation speed is decelerated by the buffer mechanism 110 acting on the rotation shaft of the arm 104. Therefore, when the door body A is closed, the rotation of the door body A is also decelerated and moderated. become. For this reason, the door body A is silently closed without causing a problem that the door body A collides with the door stop (not shown) vigorously and an impact sound is generated.
When the door body A is opened in the direction of the arrow in FIG. 9C after the door body A is closed, the pin 102a of the bracket 102 relatively moves along the guide groove 105a of the arm 104. The arm 104 rotates counterclockwise as indicated by an arrow in FIG. 9 while resisting the urging force of the spring 107, and when the arm 104 is in the state shown in FIG. 9A, the guide groove 105a of the arm 104 is rotated. And the pin 102a of the bracket 102 are disengaged, but at this disengaged position, the angle position adapted to the predetermined closing angle is held as described above.

しかしながら、上述した扉体閉止装置のように、緩衝機構１１０が取り付けられた装置本体１０１を、扉体Ａの裏面上方で、ヒンジ１０３が取着された側端に近いところに取り付け、また、ブラケット１０２を、これに対応して、上枠体Ｂの、ヒンジ１０３が取着された縦枠体Ｃの方に近いところに取り付ける構成を採ると、閉成に際して扉体Ａが静粛に閉止されるという目的は達成することができるが、扉体Ａの開成に際しては、装置本体１０１を、扉体Ａの裏面上方で、ヒンジ１０３が取着された側端とは反対側の側端に近いところに取り付け、ブラケット１０２を、これに対応して、上枠体Ｂの、縦枠体Ｄの方に近いところに取り付ける場合に比べて、当該扉体Ａの取手に加える力を大きくしなければならず、しかも、大きな力を作用させなければならないことによってヒンジに掛かる負荷が大きくなってしてしまう問題がある。
加えて、上述した扉体閉止装置において用いられている緩衝機構１１０は、ロータリー式のもので、アーム１０４の回転軸には、常に当該回転軸の回転に抗する力が作用する構造をなし、このため上述のような問題が生じてしまう一因ともなり、加えて、アーム１０４の回転時の所望時期、例えば扉体Ａの開成時にアームの回転を助長するように設定することが困難な構造となってしまう問題がある。
また、緩衝機構１１０をロータリー式のものにすると、一般に形状が大きくなり、したがって、これが取り付けられる装置本体１０１は大型化し、そのため上枠体Ｂのような幅狭い部位に装置本体１０１を取り付けることが困難となり、上述のように装置本体１０１を扉体Ａ側に、また、ブラケット１０２を上枠体Ｂに取り付けるタイプのものにならざるを得ず、見栄えの良好なタイプのものにするのを困難ならしめている。
特開２００７−１２０１４０（第４〜８頁、第１，４〜６図） However, as in the door body closing device described above, the apparatus main body 101 to which the buffer mechanism 110 is attached is attached to the upper part of the back surface of the door body A near the side end to which the hinge 103 is attached, and the bracket. Correspondingly, the door body A is silently closed when the upper frame body B is attached to a position close to the vertical frame body C to which the hinge 103 is attached. However, when opening the door body A, the apparatus main body 101 is located above the back surface of the door body A and close to the side edge opposite to the side edge to which the hinge 103 is attached. Accordingly, the force applied to the handle of the door body A must be increased compared to the case where the bracket 102 is attached to the upper frame body B at a position closer to the vertical frame body D. In addition, a great force is applied There is a problem that the load applied to the hinge resulting in increased by must.
In addition, the shock-absorbing mechanism 110 used in the door body closing device described above is of a rotary type, and has a structure in which a force against the rotation of the rotating shaft always acts on the rotating shaft of the arm 104. For this reason, the above-described problem may be caused, and in addition, a structure that is difficult to set so as to promote the rotation of the arm when the arm 104 is rotated, for example, when the door body A is opened. There is a problem that becomes.
In addition, when the buffer mechanism 110 is a rotary type, the shape is generally large. Therefore, the apparatus main body 101 to which the shock absorbing mechanism 110 is attached increases in size, so that the apparatus main body 101 can be attached to a narrow portion such as the upper frame B. As described above, the apparatus body 101 must be attached to the door body A and the bracket 102 is attached to the upper frame body B, and it is difficult to make it a good-looking type. It is being conditioned.

次に、本扉体閉止装置１の動作のしかたを図４〜６を参照して説明する。
説明の都合上、最初に本装置１の動作の概略を図６を参照して説明する。
図１のような装置本体６と被ガイド部材７との係合がなされていない状態で扉体Ａが開成されているときは、装置本体６のアーム２０は、被ガイド部材７の摺動子３１との係合が可能な所定の閉成角に適応した角度位置に保持されている。この状態から扉体Ａの取手を把持して閉成していくと、扉体Ａが本装置１の閉止動作の直前、即ち、図６（Ａ）に示す位置（本実施の形態では同図中の１５゜ぐらいの角度位置）に達したときに、摺動子３１がアーム２０のガイド溝２７ｃに係合し始め、これ以降は、摺動子３１の、アーム２０のガイド溝２７ｃに沿う相対移動に同期して、扉体Ａは、後述するように、自動的に、且つ、たとえ大きな閉成速度が与えられていても減速され静かに閉止されて図６（Ｂ）の状態になる。逆に、図６（Ｂ）の状態から図６（Ａ）の状態を経て扉体Ａを開成するときは、扉体Ａの取手を把持しラッチを外してから当該取手に力を加えればよい。このとき、上述したように、装置本体６及び被ガイド部材７の取付位置により扉体Ａの取手に加える力を大きくすることなく扉体Ａの開成が可能となり、更に、後述するようにダンパー１９の、アーム２０の回転を助長する作用により扉体Ａの取手に加える力を軽減できる。 Next, the operation of the door closing device 1 will be described with reference to FIGS.
For convenience of explanation, first, an outline of the operation of the apparatus 1 will be described with reference to FIG.

When the handle of the door body A is gripped and closed from this state, the door body A immediately before the closing operation of the apparatus 1, that is, the position shown in FIG. When the angle reaches about 15 °, the slider 31 starts to engage with the guide groove 27c of the arm 20, and thereafter, the slider 31 extends along the guide groove 27c of the arm 20. In synchronism with the relative movement, the door body A is automatically and decelerated and silently closed even when a large closing speed is given, as will be described later, and the state shown in FIG. . Conversely, when the door body A is opened from the state shown in FIG. 6B through the state shown in FIG. 6A, a force may be applied to the handle after grasping the handle of the door body A and releasing the latch. . At this time, as described above, the door body A can be opened without increasing the force applied to the handle of the door body A by the mounting positions of the apparatus main body 6 and the guided member 7, and the damper 19 is further described as will be described later. The force applied to the handle of the door body A can be reduced by the action of promoting the rotation of the arm 20.

4A shows a state immediately before the closing operation of the apparatus 1 as in FIG. 6A. The arm 20 of the apparatus main body 6 is engaged with the slider 31 of the guided member 7. It shows a state in which it is held at an angular position adapted to a predetermined closing angle that can be combined. At this time, the turning piece 14, the small rotor 23 of the times Dohen 14 the slider 15 abuts the inclined surface 15a 2 side of the slider 15, the spring 16 via the slider 15, FIG. 4 (A while receiving a clockwise moment in), the second arm portion 14b of the times Dohen 14 abuts the end surface 12b 1 of the left fixed block 12, receives moment in the counterclockwise direction from the left fixed block 12 Therefore, the arm 20 is held at an angular position adapted to the predetermined closing angle. On the other hand, in the present embodiment, the damper 19 is set so as not to exert a force on the second arm portion 14b via the slider 18.

そして、図４（Ａ）の状態から本装置１に閉止動作を開始させるために扉体Ａを閉成すべく取手に力を加えてやると、回動片１４は、当該回動片１４の小回転子２３がスライダ１５の頂点１５ａ１を乗り越えて傾斜面１５ａ３側で当該スライダ１５と当接する状態、即ち、図４（Ｂ）の状態となる。この状態になると、回動片１４は、スライダ１５を介して付与されるスプリング１６の付勢力（かかる付勢力は、調整手段１７により適宜調整できる。）により、図４（Ｂ）において反時計回り方向のモーメント（同図中の矢印方向Ａ１）を受けるようになるため、アーム２０もまた反時計回り方向のモーメント（同図中の矢印方向Ａ２）を受け、これにより扉体Ａが更に自動的に閉成されて行く。このとき、ダンパー１９は、第２スライダ１８の側面１８ａを回動片１４の第２腕部１４ｂに当接させ、第２スライダ１８を介して回動片１４に時計回り方向のモーメントを付与するので、回動片１４の反時計回り方向の回転速度は抑制されて減速される。しかるに、回動片１４が回転して図５（Ａ）の状態に達すると、図５（Ｂ）の状態に至るまで、回動片１４は、上述同様にスプリング１６の付勢力により反時計回り方向のモーメントを受け続け、これによりアーム２０もまた反時計回り方向のモーメントを受け続けるが、この回動片１４の第２腕部１４ｂのスライダ１８との当接対象部位が当該スライダ１８の傾斜面１８ａ１側に移るので、この回動片１４には当該スライダ１８を介してダンパー１９からの抗力が作用しなくなり、回動片１４が反時計回りのモーメントを受けるようになる。これにより、反時計回り方向のモーメントのみが回動片１４に作用することになるため、扉体Ａの、ラッチ孔へのラッチの没入が保証されて確実な閉止状態を得ることができる。 Then, when a force is applied to the handle to close the door body A in order to cause the device 1 to start the closing operation from the state of FIG. 4A, the rotating piece 14 becomes smaller than the rotating piece 14. state rotor 23 is in contact with the slider 15 by overcoming the apex 15a 1 inclined surface 15a 3 side of the slider 15 equivalents, i.e., a state of FIG. 4 (B). In this state, the rotating piece 14 rotates counterclockwise in FIG. 4B by the biasing force of the spring 16 applied via the slider 15 (the biasing force can be adjusted as appropriate by the adjusting means 17). The arm 20 also receives a moment in the counterclockwise direction (arrow direction A 2 in the figure) because the moment in the direction (arrow direction A 1 in the figure) is received. Goes automatically closed. At this time, the damper 19 brings the side surface 18 a of the second slider 18 into contact with the second arm portion 14 b of the rotating piece 14 and applies a clockwise moment to the rotating piece 14 via the second slider 18. Therefore, the rotational speed of the rotating piece 14 in the counterclockwise direction is suppressed and decelerated. However, when the rotating piece 14 rotates and reaches the state shown in FIG. 5A, the rotating piece 14 is rotated counterclockwise by the biasing force of the spring 16 until reaching the state shown in FIG. 5B. This causes the arm 20 to continue to receive a counterclockwise moment, but the contact portion of the second arm portion 14b of the rotating piece 14 with the slider 18 is inclined to the slider 18. since moves to the surface 18a 1 side, this is the turning piece 14 Ri no longer acts drag from the damper 19 via the slider 18, the turning piece 14 comes to receive a counter-clockwise moment. Accordingly, since the counter-clockwise direction of the moment Tonomi acts on the turning piece 14, it is possible to obtain the door A, the immersion is guaranteed reliable closed state of the latch to the latch hole.

図５（Ｂ）の状態にあるときは、回動片１４は、上述したように図５（Ｂ）において反時計回り方向のモーメントを受ける一方、当該回動片１４の第１腕部１４ａが左固定ブロック１２の傾斜面１２ａ１に当接し、当該左固定ブロック１２から時計回り方向のモーメントを受けて釣合うので、扉体の閉止状態が保持される。 5B, the rotating piece 14 receives a counterclockwise moment in FIG. 5B as described above, while the first arm portion 14a of the rotating piece 14 is in the state shown in FIG. contacts the inclined surface 12a 1 of the left fixed block 12, the balance of the left fixed block 12 receives a clockwise moment, the closed state of the door body is held.

図５（Ｂ）の状態から図４（Ａ）の状態にして扉体Ａを開成するときは、扉体Ａの取手を把持してラッチを外し当該取手に、回動片１４にスライダ１５を介して付与されるスプリング１６の付勢力（かかる付勢力は、調整手段１７により適宜調整できる。）に抗する力を加えればよい。このときの加える力は、上述したように装置本体６及び被ガイド部材７の取付位置が採用された装置１においては従来と比べて軽減することができ、しかも、ダンパー１９がスライダ１８を介して回動片１４の第２腕部１４ｂに当接し、当該回動片１４に図５（Ａ）において時計回り方向のモーメント（同図中の矢印方向Ｂ１）を付与するようになるため、アーム２０もまた時計回り方向のモーメント（同図中の矢印方向Ｂ２）を付与される。これにより、アーム２０の時計回り方向の回転が助長されるように作用するので、扉体Ａに加える力を更に軽減できる。
尚、扉体Ａの開成が進行して、装置本体６のアーム２０と被ガイド部材７の摺動子３１との係合が外れると、アーム２０が、摺動子３１との係合が可能な所定の閉成角に適応した角度位置に保持されることはもちろんである。 When the door body A is opened from the state shown in FIG. 5B to the state shown in FIG. 4A, the handle of the door body A is grasped, the latch is released, and the slider 15 is attached to the rotary piece 14 in the handle. What is necessary is just to apply the force resisting the urging force of the spring 16 applied through (the urging force can be adjusted as appropriate by the adjusting means 17). The force applied at this time can be reduced as compared with the conventional apparatus 1 in which the mounting positions of the apparatus main body 6 and the guided member 7 are adopted as described above, and the damper 19 is interposed via the slider 18. The arm 14 comes into contact with the second arm portion 14b of the rotating piece 14 and applies a moment in the clockwise direction (arrow direction B 1 in FIG. 5A) to the rotating piece 14 in FIG. 20 is also given a clockwise moment (arrow direction B 2 in the figure). Thereby, since it acts so that rotation of the arm 20 in the clockwise direction is promoted, the force applied to the door body A can be further reduced.
When the opening of the door body A proceeds and the engagement between the arm 20 of the apparatus main body 6 and the slider 31 of the guided member 7 is released, the arm 20 can be engaged with the slider 31. Needless to say, the angular position is adapted to a predetermined closing angle.

次に、図７を参照して、上記所定の閉成角に適応した角度位置に保持されていた装置本体６のアーム２０ついて、何らかの原因で上記角度位置が変わってしまう場合もあり、このような場合においてのアーム２０を上記角度位置に復帰させるやり方を説明する。
本装置１においては、上記角度位置が変わってしまっても、図７（Ａ）に示すように扉体Ａを矢印方向に移動させて（実際には扉体Ａを閉成させて）、換言すれば、被ガイド部材７を装置本体６に近づけて被ガイド部材７の摺動子３１をアーム２０の傾斜面２７ｄに当接させ、更に、当接させたまま扉体Ａを矢印方向に移動させると、図７（Ｂ）に示すように、ブロック部材３０の上面３０ａから突出していた摺動子３１は、アーム２０からの力を受け、被ガイド部材７に介装されたスプリングの付勢力に抗して押し下げられ、押し下げられた相当量だけ当該摺動子３１の下端部分がブロック部材３０の下面３０ｂから突出する。そして、このような当接状態を維持しつつ扉体Ａを更に矢印方向に移動させ続けると、図７（Ｃ）に示すように、摺動子３１がアーム２０のガイド溝２７ｃに緩挿される。このとき、下面３０ｂからの摺動子３１の突出部分はスプリングの付勢力により挿通孔に没入され、これに伴いストップリング３２が下面３０ｂに係止される。
このように一旦摺動子３１をアーム２０のガイド溝２７ｃに緩挿させた状態にしてから扉体Ａを開成させると、上述した図７（Ｃ）の状態を経て開成が進行するので、装置本体６のアーム２０と被ガイド部材７の摺動子３１との係合が解除された後は、アーム２０が、摺動子３１との係合が可能な所定の閉成角に適応した角度位置に保持され、アーム２０が上記角度位置に復帰される。 Next, referring to FIG. 7, the angular position of the arm 20 of the apparatus main body 6 held at the angular position adapted to the predetermined closing angle may change for some reason. A method for returning the arm 20 to the angular position in this case will be described.
In the present apparatus 1, even if the angular position is changed, as shown in FIG. 7A, the door body A is moved in the direction of the arrow (actually, the door body A is closed). Then, the guided member 7 is brought close to the apparatus main body 6, the slider 31 of the guided member 7 is brought into contact with the inclined surface 27d of the arm 20, and the door body A is moved in the direction of the arrow while keeping the contact. Then, as shown in FIG. 7B, the slider 31 protruding from the upper surface 30a of the block member 30 receives the force from the arm 20 and the urging force of the spring interposed in the guided member 7 The lower end portion of the slider 31 protrudes from the lower surface 30b of the block member 30 by a considerable amount pushed down. When the door body A is further moved in the arrow direction while maintaining such a contact state, the slider 31 is loosely inserted into the guide groove 27c of the arm 20 as shown in FIG. . At this time, the protruding portion of the slider 31 from the lower surface 30b is immersed in the insertion hole by the urging force of the spring, and the stop ring 32 is locked to the lower surface 30b.
When the door body A is opened after the slider 31 is loosely inserted into the guide groove 27c of the arm 20 as described above, the opening proceeds through the state shown in FIG. After the engagement between the arm 20 of the main body 6 and the slider 31 of the guided member 7 is released, the angle at which the arm 20 is adapted to a predetermined closing angle at which the engagement with the slider 31 is possible. The arm 20 is returned to the angular position.

ところで、本実施の形態のように右開き用の扉体Ａに対しては、装置本体６の外ケース本体８の下板体８ｂ側にその取付台２８ａを介してアーム２０が取り付けられるようにしたものであったが、本装置１においては、左開き用の扉体に対しても、このアーム２０を装置本体６の外ケース本体８の上板体８ａ側に当該アーム２０の取付台２８ａを介して取り付けることで対応できる。具体的には、アーム２０において、取付台２８ａの径大嵌合軸２８ａ１をケース本体８の挿通穴８ａ１に、また、取付台２８ａの径小嵌合軸２８ａ２を内ケース上板体１１の軸受リング２１ｂに、また、取付台２８ａの連結軸２８ａ３を回動片１４の軸部１４ｃの角穴及び小軸部１４ｃ１の角穴にそれぞれ緩嵌させ、しかる後に、取付ボルト２９を、アーム２０の上底面２７側から取付台２８ａの嵌合軸２８ａ１，２８ａ２及び連結軸２８ａ３のねじ孔に螺着させることで対応できる。したがって、本装置１は、右開き扉用としても左開き扉用としても兼用できるので、設置作業に際しての使い勝手の向上が図れる。 By the way, the arm 20 is attached to the lower plate body 8b side of the outer case main body 8 of the apparatus main body 6 via the mounting base 28a with respect to the door body A for right opening as in the present embodiment. However, in the present apparatus 1, the arm 20 is attached to the upper plate body 8a side of the outer case body 8 of the apparatus main body 6 even with respect to the door body for the left opening. It can respond by attaching it via. Specifically, in the arm 20, a large diameter fitting shaft 28a 1 of the mount 28a into the insertion hole 8a 1 of the case body 8, also the small-diameter fitting shaft 28a 2 of the mount 28a inner housing upper plate body the bearing ring 21b of 11, also is each connecting shaft 28a 3 of the mount 28a into the square hole and square hole of the small shaft portion 14c 1 of the shaft portion 14c of the turning piece 14 loosely fitted, and thereafter, mounting bolt 29 Can be accommodated by screwing them into the screw holes of the fitting shafts 28a 1 and 28a 2 and the connecting shaft 28a 3 of the mounting base 28a from the upper bottom surface 27 side of the arm 20. Therefore, since this apparatus 1 can be used for both the right-opening door and the left-opening door, it is possible to improve the ease of use during installation work.

本発明の扉体閉止装置は、装置本体に取り付ける緩衝装置を直動式タイプのものとすることにより装置本体のコンパクト化が図られており、そのためスペースの狭い枠体に取付けることができる装置構造としている点で、また、緩衝装置を、扉体の閉成に際しては当該扉体の閉成速度を減速して静かに閉止するように作用させる一方、扉体の開成に際しては当該扉体の取手に大きな力を加えずに済むように作用させる装置構造としている点で、この種の装置として広く一般的に利用されるものと言える。   The door body closing device according to the present invention is a device structure that can be attached to a frame having a small space because the shock absorber attached to the device body is of a direct acting type so that the device body is made compact. In addition, when the door body is closed, the shock absorber is operated so as to quietly close the door body by reducing the closing speed of the door body, while the door body handle is opened when the door body is opened. Therefore, it can be said that this type of device is widely used in general because it has a device structure that does not require a large force to be applied.
