特開２００７−３０８８８８号公報JP 2007-308888 A

上記特許文献１に記載の開き戸の緩衝装置は、強風や室内外の気圧差などにより開き戸が勢い良く閉まるのを防止するものであるが、開き戸が閉まり際において少し開いた状態で閉められた場合に対処する機能は具備されていないものである。   The shock absorber for the hinged door described in Patent Document 1 prevents the hinged door from closing with a strong wind or a pressure difference between the inside and outside of the room, but when the hinged door is closed in a slightly opened state when it is closed. The function which copes with is not equipped.

本発明の目的は、このような課題を解決するものであり、開き戸が閉まり際において少し開いた状態で閉められた場合、開き戸を閉まり際からブレーキを掛けながら引き寄せ、開き戸を完全に閉じた状態に保持するようにした開き戸装置を提供することにある。   The object of the present invention is to solve such a problem, and when the hinged door is closed in a slightly opened state, the hinged door is pulled while applying a brake when the hinged door is closed, and the hinged door is completely closed. An object of the present invention is to provide a hinged door device that is held in the door.

本発明の請求項１に記載の開き戸装置は、建物の出入り口の縦枠に一側部が蝶番により鉛直軸芯の周りで回転可能に支持された開き戸を備え、この開き戸の一側部側には前記縦枠の内面側に設けられている磁性板に先端面が対向するマグネットを設けるとともに、縦枠の内面側に対向する緩衝用のダンパーを設け、このダンパーの作動ピンの先端が前記縦枠の内面側に当接することにより、前記マグネットによる磁性板の吸着作用による開き戸の閉まり際からの閉動時に開き戸にブレーキを掛けるようにしたことを特徴とする。   The hinged door device according to claim 1 of the present invention includes a hinged door whose one side is rotatably supported around a vertical axis by a hinge on a vertical frame of a doorway of the building, on one side of the hinged door. The magnetic plate provided on the inner surface side of the vertical frame is provided with a magnet facing the front end surface, and a damper for buffering is provided facing the inner surface side of the vertical frame. By contacting the inner surface of the frame, a brake is applied to the hinged door when the hinged door is closed due to the magnetic plate attracting action of the magnet.

以上のように、本発明の開き戸装置は、開き戸が閉まり際において少し開くような弱い力で閉じられた場合でも、閉まり際においてマグネットの先端面で磁性板を吸着する作用が働き、その力により開き戸は閉まり際から完全に閉じられることになる。そのとき、マグネットが磁性板を吸着する働きにより、開き戸１は急激に閉まる惧れがあるが、前記ダンパーの作動ピンの先端が縦枠の内面側を押し付けるように働くことになり、開き戸にブレーキが掛けられ、開き戸が急激に閉まるのを防止することができる。   As described above, even when the hinged door device of the present invention is closed with a weak force that slightly opens when the hinged door is closed, the action of adsorbing the magnetic plate at the tip end surface of the magnet works when the hinged door is closed. The hinged door will be completely closed when it closes. At that time, the hinge 1 may close suddenly due to the magnet adsorbing the magnetic plate, but the tip of the operating pin of the damper acts to press the inner surface side of the vertical frame, and the brake is applied to the hinged door. It is possible to prevent the hinged door from closing suddenly.

以下、本発明の実施の形態を、図面を用いて具体的に説明する。
先ず、図１〜図５に示す第１の実施の形態について説明すると、１は建物に形成された出入り口２を開閉自在とするために出入り口２を形成する縦枠３に一側部が上下２箇所で蝶番４により支持され鉛直軸芯の周りで回転可能な開き戸であって、蝶番４の軸部５を中心に回動する２枚の羽根６，７の内、一方の羽根６は縦枠３の内面側にビス８止めされ、他方の羽根７は開き戸１の一側部端面にビス８止めされている。９は開き戸１の一側部端面の上端近傍に形成された凹部１０に先端面が開き戸１の一側部端面に揃うように埋設されたマグネットで、このマグネット９は凹部１０に嵌入された状態で中心より螺入されるねじ１１により固定されている。そして、このマグネット９の先端面に対向するように縦枠３の内面側に磁性板１２がビス１３止めにて取り付けられている。 Embodiments of the present invention will be specifically described below with reference to the drawings.
First, the first embodiment shown in FIGS. 1 to 5 will be described. In order to make the doorway 2 formed in a building openable and closable, 1 has a vertical frame 3 that forms the doorway 2 and one side portion is vertically 2. A hinged door that is supported by a hinge 4 at a location and is rotatable about a vertical axis. Of the two blades 6 and 7 that rotate about the shaft portion 5 of the hinge 4, one blade 6 is a vertical frame. A screw 8 is fixed to the inner surface side of the door 3, and the other blade 7 is fixed to the end surface of one side of the hinged door 1 with a screw 8. Reference numeral 9 denotes a magnet embedded in a recess 10 formed near the upper end of one side end face of the hinged door 1 so that the front end face is aligned with the end face of one side of the hinged door 1. The magnet 9 is fitted in the recess 10. And fixed by a screw 11 screwed from the center. A magnetic plate 12 is attached to the inner surface side of the vertical frame 3 with screws 13 so as to face the front end surface of the magnet 9.

これにより、開き戸１が閉まり際において少し開くような弱い力で閉じられた場合でも、閉まり際において前記マグネット９の先端面で磁性板１２を吸着する作用が働き、その力により開き戸１は閉まり際から完全に閉じられることになる。そのとき、マグネット９が磁性板１２を吸着する働きにより、開き戸１は急激に閉まる惧れがある。そこで、本実施の形態では開き戸１の内面の上端近傍にオイルが充填された緩衝用のミニダンパー１４が装着されている。詳しくは、ミニダンパー１４は開き戸１の内面の上端近傍にビス１５止めされたダンパー保持部材１６に差し込まれて作動ピン１４ａが開き戸１の一側部端面から突出するように設けられており、マグネット９の吸着力により開き戸１が閉まり際から閉じられるとき、ミニダンパー１４の作動ピン１４ａの先端が前記縦枠３の内面側の幅方向中央の膨らみ部３ａを押し付けるように働くことになり、開き戸１にブレーキが掛けられ、開き戸１が急激に閉まるのを防止できる。   As a result, even when the hinged door 1 is closed with a weak force that opens slightly when the hinged door 1 is closed, the magnetic plate 12 is attracted by the tip surface of the magnet 9 when the hinged door is closed, and the force is applied when the hinged door 1 is closed. Will be completely closed. At that time, there is a possibility that the hinged door 1 is suddenly closed by the action of the magnet 9 attracting the magnetic plate 12. Therefore, in the present embodiment, a buffer mini-damper 14 filled with oil is mounted near the upper end of the inner surface of the hinged door 1. Specifically, the mini damper 14 is provided in such a manner that the operation pin 14a protrudes from one side end surface of the hinged door 1 by being inserted into a damper holding member 16 secured to the screw 15 near the upper end of the inner surface of the hinged door 1. 9, when the hinged door 1 is closed from the time of closing, the tip of the operating pin 14 a of the mini-damper 14 works so as to press the bulging portion 3 a at the center in the width direction on the inner surface side of the vertical frame 3. 1 is braked, and the hinged door 1 can be prevented from closing suddenly.

次に、図６〜図８に示す第２の実施の形態について説明すると、前記第１の実施の形態ではマグネット９とミニダンパー１４が別々に取り付けられているが、第２の実施の形態ではマグネット９とミニダンパー１４は開き戸１の一側部端面にビス８止めされる上下の蝶番４の内、上側の蝶番４の他方の羽根７の背面側に一体に形成されたケーシング１７内に設けられている点で異なり、マグネット９の先端面およびミニダンパー１４の作動ピン１４ａは他方の羽根７に形成された開口孔７ａおよび７ｂより露出している。具体的には、ケーシング１７は他方の羽根７の背面側に縦向きに形成され、マグネット９は他方の羽根７の上下方向中央に形成された開口孔７ａよりケーシング１７内に横方向から挿入されて、中心より螺入されるねじ１８によりケーシング１７に固定されており、またミニダンパー１４は開口孔７ａの上下両側で他方の羽根７に形成された開口孔７ｂより横方向から２本ケーシング１７内に挿入され、そのときミニダンパー１４の作動ピン１４ａは開口孔７ｂより突出するようにケーシング１７内に挿入されるものである。そして、蝶番４の他方の羽根７と一体のケーシング１７は開き戸１の一側部端面に形成された凹部１９内に埋め込まれるのであり、ケーシング１７が凹部１９内に埋め込まれた状態で他方の羽根７は開き戸１の一側部端面にビス８止めされる。なお、この第２の実施の形態の場合、第１の実施の形態のようなマグネット９の先端面に対向する磁性板１２を別に設ける必要がなく、縦枠３の内面側にビス８止めされる蝶番４の一方の羽根６が磁性板を兼ねるようになる。そのためには蝶番４は鉄などの磁性材料で作られていることは言うまでもない。   Next, the second embodiment shown in FIGS. 6 to 8 will be described. In the first embodiment, the magnet 9 and the mini-damper 14 are separately attached. In the second embodiment, The magnet 9 and the mini-damper 14 are provided in a casing 17 integrally formed on the back side of the other blade 7 of the upper hinge 4 among the upper and lower hinges 4 fixed to the one side end face of the hinged door 1 by screws 8. However, the tip surface of the magnet 9 and the operating pin 14a of the mini-damper 14 are exposed through opening holes 7a and 7b formed in the other blade 7. Specifically, the casing 17 is formed vertically on the back side of the other blade 7, and the magnet 9 is inserted into the casing 17 from the lateral direction through an opening hole 7 a formed at the center in the vertical direction of the other blade 7. The mini-damper 14 is fixed to the casing 17 by a screw 18 screwed from the center, and the mini-damper 14 has two casings 17 from the lateral direction from the opening hole 7b formed on the other blade 7 on both the upper and lower sides of the opening hole 7a. The operating pin 14a of the mini damper 14 is inserted into the casing 17 so as to protrude from the opening hole 7b. The casing 17 integral with the other blade 7 of the hinge 4 is embedded in a recess 19 formed on one end face of the hinged door 1, and the other blade is in a state where the casing 17 is embedded in the recess 19. 7 is fixed to one side end face of the hinged door 1 by screws 8. In the case of the second embodiment, there is no need to separately provide a magnetic plate 12 facing the tip surface of the magnet 9 as in the first embodiment, and the screw 8 is fixed to the inner surface side of the vertical frame 3. One blade 6 of the hinge 4 is also used as a magnetic plate. Needless to say, the hinge 4 is made of a magnetic material such as iron.

これにより、開き戸１が閉まり際において少し開くような弱い力で閉じられた場合でも、閉まり際において前記マグネット９の先端面で蝶番４の一方の羽根６を吸着する作用が働き、その力により開き戸１は閉まり際から完全に閉じられることになる。そのとき、マグネット９が磁性板を兼ねた一方の羽根６を吸着する働きにより、開き戸１は急激に閉まる惧れがある。そのときミニダンパー１４の作動ピン１４ａの先端が前記蝶番４の一方の羽根６を押し付けるように働くことになり、開き戸１にブレーキが掛けられ、開き戸１が急激に閉まるのを防止できる。   Thereby, even when the hinged door 1 is closed with a weak force that slightly opens when the hinged door is closed, the action of adsorbing one blade 6 of the hinge 4 on the front end surface of the magnet 9 acts when the hinged door is closed, and the force is used to open the hinged door. 1 is completely closed when it is closed. At that time, the swing door 1 may be abruptly closed by the action of the magnet 9 attracting the one blade 6 also serving as a magnetic plate. At that time, the tip of the operating pin 14a of the mini-damper 14 works to press the one blade 6 of the hinge 4, so that the hinged door 1 is braked and the hinged door 1 can be prevented from closing suddenly.

次に、図９〜図１０に示す第３の実施の形態について説明すると、この実施の形態ではケーシング２０内にマグネット９とミニダンパー１４を挿入しているのであって、具体的には縦向きのケーシング２０内には上下両端近傍に横方向からマグネット９を挿入し、この両マグネット９間にミニダンパー１４を横方向から挿入している。そのとき、マグネット９の先端面およびミニダンパー１４の作動ピン１４ａはケーシング２０の先端面の開口孔２０ａおよび２０ｂより露出している。さらに詳しくは、マグネット９はケーシング２０の開口孔２０ａよりケーシング２０内に挿入されて、中心より螺入されるねじ２１によりケーシング２０に固定されており、またミニダンパー１４は開口孔２０ｂよりケーシング２０内に挿入され、そのときミニダンパー１４の作動ピン１４ａは開口孔２０ｂより突出するようにケーシング２０内に挿入されるものである。ところで、前記マグネット９およびミニダンパー１４が挿入されたケーシング２０は開き戸１の一側部端面の上端近傍に形成された凹部２２内に埋め込まれるのであり、凹部２２内に埋め込まれたケーシング２０は上下に突出するフランジ２３を凹部２２の上下の段差部２２ａに当ててビス２４止めされるものである。この状態においてマグネット９の先端面が開き戸１の一側部端面に揃うようになる。そして、前記マグネット９の先端面に対向するように縦枠３の内面側に磁性板２５がビス２６止めにて取り付けられている。   Next, a third embodiment shown in FIGS. 9 to 10 will be described. In this embodiment, the magnet 9 and the mini-damper 14 are inserted into the casing 20, and specifically, vertically oriented. In the casing 20, magnets 9 are inserted in the vicinity of both upper and lower ends from the lateral direction, and a mini damper 14 is inserted between the magnets 9 from the lateral direction. At that time, the front end surface of the magnet 9 and the operating pin 14 a of the mini damper 14 are exposed from the opening holes 20 a and 20 b on the front end surface of the casing 20. More specifically, the magnet 9 is inserted into the casing 20 through the opening hole 20a of the casing 20, and is fixed to the casing 20 by a screw 21 screwed from the center, and the mini damper 14 is fixed to the casing 20 through the opening hole 20b. The operating pin 14a of the mini damper 14 is inserted into the casing 20 so as to protrude from the opening hole 20b. By the way, the casing 20 in which the magnet 9 and the mini-damper 14 are inserted is embedded in a recess 22 formed near the upper end of one side end face of the hinged door 1, and the casing 20 embedded in the recess 22 is vertically The flange 23 protruding to the upper and lower portions 22a of the concave portion 22 is applied to the upper and lower step portions 22a to be fastened with screws 24. In this state, the tip surface of the magnet 9 is aligned with the end surface of one side of the hinged door 1. A magnetic plate 25 is attached to the inner surface side of the vertical frame 3 with screws 26 so as to face the front end surface of the magnet 9.

これにより、開き戸１が閉まり際において少し開くような弱い力で閉じられた場合でも、閉まり際において前記マグネット９の先端面で磁性板２４を吸着する作用が働き、その力により開き戸１は閉まり際から完全に閉じられることになる。そのとき、マグネット９が磁性板２５を吸着する働きにより、開き戸１は急激に閉まる惧れがある。そのときミニダンパー１４の作動ピン１４ａの先端が前記磁性板２５を押し付けるように働くことになり、開き戸１にブレーキが掛けられ、開き戸１が急激に閉まるのを防止できる。   As a result, even when the hinged door 1 is closed with a weak force that slightly opens when the hinged door 1 is closed, the magnetic plate 24 is attracted by the tip surface of the magnet 9 when the hinged door is closed. Will be completely closed. At that time, the swing door 1 may be abruptly closed due to the magnet 9 attracting the magnetic plate 25. At that time, the tip of the operating pin 14a of the mini-damper 14 works so as to press the magnetic plate 25, the brake is applied to the hinged door 1, and the hinged door 1 can be prevented from closing suddenly.

次に、図１１〜図１２に示す第４の実施の形態について説明すると、この実施の形態は前記第３の実施の形態と同様に、ケーシング２０内にマグネット９とミニダンパー１４を挿入したものを用い、このユニットを開き戸１の内面の上端近傍で、マグネット９の先端面が開き戸１の一側部端面より僅かに後退するように開き戸１の内面の上端近傍に予め取り付けてある保持ケース２７に差し込み、ケーシング２０のフランジ２３を保持ケース２７に対してビス２８止めし、ケーシング２０が先端面を残してカバー２９で覆われるものである。この第４の実施の形態ではマグネット９を備えたユニットの先端面に対向するように縦枠３の内面側の幅方向中央の膨らみ部３ａに磁性板３０がビス３１止めにて取り付けられている。   Next, a fourth embodiment shown in FIGS. 11 to 12 will be described. In this embodiment, a magnet 9 and a mini-damper 14 are inserted into a casing 20 as in the third embodiment. The holding case 27 is attached in advance to the vicinity of the upper end of the inner surface of the hinged door 1 so that the front end surface of the magnet 9 slightly recedes from the end surface of one side of the hinged door 1 near the upper end of the inner surface of the hinged door 1. The flange 20 of the casing 20 is fixed to the holding case 27 with a screw 28, and the casing 20 is covered with a cover 29 leaving a tip end surface. In the fourth embodiment, the magnetic plate 30 is attached to the bulging portion 3a at the center in the width direction on the inner surface side of the vertical frame 3 with screws 31 so as to face the front end surface of the unit including the magnet 9. .

これにより、開き戸１が閉まり際において少し開くような弱い力で閉じられた場合でも、閉まり際において前記マグネット９の先端面で磁性板３０を吸着する作用が働き、その力により開き戸１は閉まり際から完全に閉じられることになる。そのとき、マグネット９が磁性板３０を吸着する働きにより、開き戸１は急激に閉まる惧れがある。そのときミニダンパー１４の作動ピン１４ａの先端が前記磁性板３０を押し付けるように働くことになり、開き戸１にブレーキが掛けられ、開き戸１が急激に閉まるのを防止できる。   As a result, even when the hinged door 1 is closed with a weak force that opens slightly when the hinged door 1 is closed, the magnetic plate 30 is attracted by the tip surface of the magnet 9 when the hinged door is closed, and the force is applied when the hinged door 1 is closed. Will be completely closed. At that time, the hinged door 1 may be abruptly closed due to the magnet 9 attracting the magnetic plate 30. At that time, the tip of the operating pin 14a of the mini-damper 14 works so as to press the magnetic plate 30, so that the hinged door 1 is braked and the hinged door 1 can be prevented from closing suddenly.
