Description

本発明は所定開き角度まで閉じたドアを自動的に閉じるドア引き込み装置に関する。   The present invention relates to a door retracting device that automatically closes a door that is closed to a predetermined opening angle.

従来のドア引き込み装置としては例えば特許文献1に示すものが知られている。このものは、ドア枠の上横枠に引き込み機構部が設けられ、該引き込み機構部は縦軸回りに回動自在に設けられたアームを備えている。そして、ドアを閉じた際には、ドアに設けられたピンが手先側斜め前方に突出したアームの長溝に導入されて係止され、この後、ばねの弾性力によりアームを後方に回動させることで、ドアが自動的に閉じられるようになっている。   As a conventional door retracting device, for example, the one disclosed in Patent Document 1 is known. In this device, a retracting mechanism is provided on the upper horizontal frame of the door frame, and the retracting mechanism is provided with an arm provided so as to be rotatable about a vertical axis. When the door is closed, the pin provided on the door is introduced and locked into the long groove of the arm that projects obliquely forward on the hand side, and thereafter the arm is rotated backward by the elastic force of the spring. As a result, the door is automatically closed.

しかし、前記特許文献1のドア引き込み装置は、前記アームが前後に回動するものであるので、引き込み機構部を上横枠の前後幅内にコンパクトに収めることが難しくなる。このため、ドアが開状態にあるときにアームが上横枠よりも前方に突出して見栄えを悪くしたり、前後幅の小さい上横枠に引き込み機構部を設けることができない場合がある。
特開2006−283460号公報
However, in the door retracting device of Patent Document 1, since the arm pivots back and forth, it is difficult to fit the retracting mechanism portion compactly within the longitudinal width of the upper horizontal frame. For this reason, when the door is in the open state, the arm may protrude forward from the upper horizontal frame to deteriorate the appearance, or the retracting mechanism portion may not be provided in the upper horizontal frame having a small front-rear width.
JP 2006-283460 A

本発明は上記従来の問題点に鑑みてなされたものであって、引き込み機構部を上横枠の前後幅内にコンパクトに収めることができ、しかも、確実にドアを引き込むことができ、また、ドア幅やドアの重量、使用方法等に応じてドアの引き込み開始位置を調節することができるドア引き込み装置を提供することを課題とする。   The present invention has been made in view of the above-described conventional problems, and the retracting mechanism can be compactly accommodated within the front and rear width of the upper horizontal frame, and the door can be reliably retracted, It is an object of the present invention to provide a door pull-in device capable of adjusting the door pull-in start position according to the door width, door weight, usage method, and the like.

上記課題を解決するために、本発明のドア引き込み装置は、ドア枠2の上横枠7に設けられる引き込み機構部10と、ドア1の上端部に設けられてドア1から背方に突出する被キャッチ部9を備え、前記引き込み機構部10は、ドア1を所定開き角度まで閉じたときに前記被キャッチ部9に着脱自在に係合するキャッチャー14と、前記被キャッチ部9に係合したキャッチャー14を上横枠7の長手方向の吊元側に駆動させてドア1を閉状態とする駆動部16を備え、前記被キャッチ部9がドア1の幅方向の位置を調節可能とされることを特徴とする。なお、ここでは、ドア1の厚み方向を前後方向と定義すると共に閉止状態にあるドア1を開く際にドア1を動作させる方向を前側と定義している。   In order to solve the above-described problem, the door retracting device of the present invention is provided at the upper horizontal portion 7 of the door frame 2 and at the upper end portion of the door 1 and protrudes backward from the door 1. A catching portion 9 is provided, and the retracting mechanism portion 10 engages with the catched portion 9 and a catcher 14 that detachably engages with the caught portion 9 when the door 1 is closed to a predetermined opening angle. A drive unit 16 that drives the catcher 14 to the suspending side in the longitudinal direction of the upper horizontal frame 7 to close the door 1 is provided, and the catched portion 9 can adjust the position of the door 1 in the width direction. It is characterized by that. Here, the thickness direction of the door 1 is defined as the front-rear direction, and the direction in which the door 1 is operated when the door 1 in the closed state is opened is defined as the front side.

本発明にあっては、被キャッチ部が係合したキャッチャーを上横枠の長手方向に駆動してドアを自動的に閉状態とすることができ、これにより、引き込み機構部の前後幅を小さくして、平面視において上横枠の前後幅内に引き込み機構部をコンパクトに収めることができる。   In the present invention, the door can be automatically closed by driving the catcher engaged with the catched portion in the longitudinal direction of the upper horizontal frame, thereby reducing the front-rear width of the retracting mechanism portion. Thus, the retracting mechanism can be compactly accommodated within the front-rear width of the upper horizontal frame in plan view.

しかも、被キャッチ部の左右方向の位置を調節することができるため、被キャッチ部をキャッチャーに確実に係合させ、確実にドアを引き込むことができる。さらに、ドア幅やドアの重量、使用方法等に応じて、引き込み機構部によるドアの引き込み開始位置を調節することができる。   In addition, since the position of the catched portion in the left-right direction can be adjusted, the catched portion can be reliably engaged with the catcher and the door can be reliably pulled in. Furthermore, the retracting start position of the door by the retracting mechanism can be adjusted according to the door width, door weight, usage method, and the like.

以下、本発明の実施形態の一例を添付図面に基づいて説明する。なお、以下では、上横枠7の長手方向及びドア1の幅方向を左右方向、平面視で上横枠7の長手方向と直交する方向及びドア1の厚み方向を前後方向と定義する。また、閉止状態にあるドア1を開く際にドア1を動作させる方向を前側とする。   Hereinafter, an example of an embodiment of the present invention will be described with reference to the accompanying drawings. In the following, the longitudinal direction of the upper horizontal frame 7 and the width direction of the door 1 are defined as the left-right direction, the direction orthogonal to the longitudinal direction of the upper horizontal frame 7 in plan view, and the thickness direction of the door 1 are defined as the front-rear direction. Moreover, let the direction which operates the door 1 when opening the door 1 in a closed state be a front side.

本例のドア引き込み装置は後述のドア緩衝装置と併せてドア開閉駆動装置を構成するものであり、所定開き角度まで閉じた閉じ際のドア1をドア開閉駆動装置の働きによりゆっくりと自動的に閉じられるようになっている。このうち、ドア引き込み装置は所定開き角度まで閉じた閉じ際のドア1を自動的に閉じる機能を担い、ドア緩衝装置はドア1が閉じられる際に生じる衝撃を緩和する機能を担う。   The door retracting device of this example constitutes a door opening / closing drive device together with a door shock absorber described later, and the door 1 when closed to a predetermined opening angle is automatically and slowly closed by the action of the door opening / closing drive device. It is designed to be closed. Among these, the door retracting device has a function of automatically closing the door 1 when closed to a predetermined opening angle, and the door shock absorber has a function of alleviating an impact generated when the door 1 is closed.

図7等に示すようにドア1の側端部はドア枠2の一方の縦枠3に蝶番4を介して回動自在に連結されている。ドア枠2の後部の内周面には戸当たり5が突設され、ドア1はその背面縁部を戸当たり5に当接した閉状態において、その全部がドア枠2内に収められる。   As shown in FIG. 7 and the like, the side end of the door 1 is rotatably connected to one vertical frame 3 of the door frame 2 via a hinge 4.

図3や図5に示すように、ベース13は左右に長尺で下方に開口する略溝型に形成され、上横枠7の後部下面に形成された左右に長い嵌込溝20に嵌め込まれ、ベース13の後面部の下縁から後方に突出した後縁片18を上横枠7の下面に沿わせた状態で上横枠7に取り付けられる。ベース13は平面視で上横枠7の前後幅内に収まり、且つ、前記上横枠7に設けられた戸当たり5の前端よりも後方に配置される。   As shown in FIGS. 3 and 5, the base 13 is formed in a substantially groove shape that is long on the left and right and opens downward, and is fitted in a long fitting groove 20 on the left and right formed on the rear lower surface of the upper horizontal frame 7. The rear edge piece 18 protruding rearward from the lower edge of the rear surface portion of the base 13 is attached to the upper horizontal frame 7 along the lower surface of the upper horizontal frame 7. The base 13 is accommodated within the front-rear width of the upper horizontal frame 7 in plan view, and is disposed rearward of the front end of the door stop 5 provided on the upper horizontal frame 7.

ガイド部材17はベース13の吊元側の内部に収納され、ベース13に対して固定される。図10に示すようにガイド部材17の内部には左右に長く下方及び手先側(左右方向における吊元側と反対側)に開口するスライド溝21が形成されている。   The guide member 17 is housed inside the base 13 and is fixed to the base 13. As shown in FIG. 10, a slide groove 21 is formed in the guide member 17 that is long in the left and right and opens downward and on the hand side (on the opposite side to the suspension side in the left-right direction).

スライド溝21の開口22はガイド部材17の手先側の端面から下面に亘って形成されている。この開口22が形成されたガイド部材17の鉛直な端面によってロック部25が構成され、同じく開口22が形成されたガイド部材17の水平な下面によってレール部24が構成されている。また、レール部24とロック部25は正面視弧状の面からなるガイド部26によって滑らかに接続されている。   The opening 22 of the slide groove 21 is formed from the end surface on the hand side of the guide member 17 to the lower surface. A lock portion 25 is constituted by a vertical end surface of the guide member 17 in which the opening 22 is formed, and a rail portion 24 is constituted by a horizontal lower surface of the guide member 17 in which the opening 22 is also formed. Moreover, the rail part 24 and the lock | rock part 25 are smoothly connected by the guide part 26 which consists of a front view arc-shaped surface.

駆動部16は、ベース13に対して左右方向にスライド自在に設けられた左右に長い移動部材28と、移動部材28に対して左右方向における吊元側へ駆動する方向に弾性力を付勢する弾性部材29とで構成されている。   The drive unit 16 urges an elastic force in the direction of driving to the suspension side in the left-right direction with respect to the moving member 28 that is provided to be slidable in the left-right direction with respect to the base 13. And an elastic member 29.

移動部材28の手先側には左右に長く上方に開口したばね収納溝30(図11参照)が形成されている。ばね収納溝30には引張ばねが収納され、該引張ばねにより弾性部材29が構成されている。   A spring housing groove 30 (see FIG. 11) is formed on the hand side of the moving member 28. A tension spring is accommodated in the spring accommodating groove 30, and an elastic member 29 is constituted by the tension spring.

弾性部材29の吊元側の端部はベース13に係止され、反対側の端部は移動部材28に係止される。これによって移動部材28は弾性部材29により常に吊元側に付勢される。移動部材28の吊元側の端部には下方に開口する配置溝31(図10参照)が形成されている。   The end of the elastic member 29 on the suspending side is locked to the base 13, and the end on the opposite side is locked to the moving member 28. Accordingly, the moving member 28 is always urged toward the suspension side by the elastic member 29. A disposition groove 31 (see FIG. 10) that opens downward is formed at the end of the moving member 28 on the suspending side.

移動部材28の吊元側の端部には被キャッチ部9に着脱自在に係合可能となるキャッチャー14がその上部を配置溝31内に収めた状態で左右に回動自在に設けられている。キャッチャー14の回動軸方向は前後方向と平行である。   A catcher 14 that can be detachably engaged with the catched portion 9 is provided at the end of the suspending side of the moving member 28 so that the upper portion of the catcher 14 is accommodated in the arrangement groove 31 and can be rotated to the left and right. . The rotation axis direction of the catcher 14 is parallel to the front-rear direction.

キャッチャー14は前記駆動部16の弾性部材29によって移動部材28を吊元側に駆動することで、左右方向における吊元側に移動する。   The catcher 14 moves to the suspension side in the left-right direction by driving the moving member 28 to the suspension side by the elastic member 29 of the drive unit 16.

キャッチャー14は前後方向の厚みが薄く且つ正面視略逆U字状の部材からなり、吊元側から下方に突出する第1爪部33と、手先側から下方に突出する第2爪部34と、両突部33、34の突出基端同士を接続する接続部35を備えている。キャッチャー14の両突部33、34の間には前後及び下方に開口する開口部36が形成されている。   The catcher 14 is made of a member that is thin in the front-rear direction and has a substantially inverted U-shape when viewed from the front, and includes a first claw portion 33 that protrudes downward from the suspension side, and a second claw portion 34 that protrudes downward from the hand side. Further, a connecting portion 35 that connects the protruding proximal ends of the protruding portions 33 and 34 is provided. An opening 36 is formed between the protrusions 33 and 34 of the catcher 14 so as to open forward and backward and downward.

キャッチャー14の上部に位置する接続部35には前後方向に突出する被枢支部37が形成され、この被枢支部37が移動部材28の吊元側端部に枢支されることで、キャッチャー14が移動部材28に対して回動自在となっている。
キャッチャー14は図11に示す手先側の斜め下方に向けて開口する待機姿勢から図9に示す略鉛直下向きに開口する係合姿勢までの範囲で回動可能としてある。キャッチャー14の上部は前記待機姿勢及び係合姿勢となったときに移動部材28に当接され、これによってキャッチャー14の回動範囲は前記待機姿勢から係合姿勢までの範囲に制限されている。キャッチャー14の手先側の部分の前後両側には被ガイド部38が突出形成されている。
The connecting portion 35 located at the upper portion of the catcher 14 is formed with a pivoted support portion 37 that protrudes in the front-rear direction. The pivoted support portion 37 is pivotally supported by the suspension-side end portion of the moving member 28. Is rotatable with respect to the moving member 28.
The catcher 14 is rotatable in a range from a standby posture that opens obliquely downward on the hand side shown in FIG. 11 to an engagement posture that opens substantially vertically downward as shown in FIG. 9. The upper portion of the catcher 14 is brought into contact with the moving member 28 when the standby posture and the engagement posture are reached, and thereby the rotation range of the catcher 14 is limited to the range from the standby posture to the engagement posture. Guided portions 38 are formed to project from both the front and rear sides of the hand side portion of the catcher 14.

移動部材28の吊元側の端部はガイド部材17のスライド溝21に左右方向にスライド自在に収納されている。   The end of the moving member 28 on the suspending side is housed in the slide groove 21 of the guide member 17 so as to be slidable in the left-right direction.

キャッチャー14の両被ガイド部38はガイド部材17のレール部24、ロック部25、又はガイド部26に沿って配置される。   Both guided portions 38 of the catcher 14 are arranged along the rail portion 24, the lock portion 25, or the guide portion 26 of the guide member 17.

キャッチャー14は、両被ガイド部38が図13に示すようにガイド部材17によりガイドされ、これに伴いキャッチャー14は、両被ガイド部38がロック部25に沿う待機姿勢から、両被ガイド部38がレール部24に沿う係合姿勢までの範囲内で回動する。   In the catcher 14, the both guided portions 38 are guided by the guide member 17 as shown in FIG. 13, and accordingly, the catcher 14 has the both guided portions 38 in a standby posture along which the both guided portions 38 are along the lock portion 25. Rotates within a range up to the engagement posture along the rail portion 24.

図12(a)及び図13(a)に示すキャッチャー14は弾性部材29により移動部材28が吊元側に付勢され、且つ、両被ガイド部38がロック部25に当接し、且つ前記待機姿勢となったロック状態にある。このロック状態では、キャッチャー14の第1爪部33は、ベース13、ガイド部材17、及び第2爪部34よりも下方に突出している。   In the catcher 14 shown in FIGS. 12A and 13A, the moving member 28 is urged toward the suspension side by the elastic member 29, the both guided portions 38 abut against the lock portion 25, and the standby It is in a locked state in a posture. In this locked state, the first claw portion 33 of the catcher 14 protrudes below the base 13, the guide member 17, and the second claw portion 34.

今、キャッチャー14が前記ロック状態にあるときに、ドア1を開いた状態から人の手により閉方向に回動させる。すると、ドア1から背方に突出した被キャッチ部9は、図12の(a)〜(c)や図13の(a)〜(d)に示すように正面視で左右方向における吊元側に移動し、ドア1が所定開き角度まで閉じられたときにキャッチャー14に係合される。   Now, when the catcher 14 is in the locked state, the door 1 is rotated in the closing direction by a human hand from the opened state. Then, the catched portion 9 protruding rearward from the door 1 is a suspension base side in the left-right direction in front view as shown in FIGS. 12 (a) to 12 (c) and FIG. 13 (a) to (d). When the door 1 is closed to a predetermined opening angle, it is engaged with the catcher 14.

具体的には、開いたドア1を所定開き角度まで閉じたときには、まず図13(a)に示すように被キャッチ部9がロック状態にあるキャッチャー14の第2爪部34の下側を通過して、図13(b)に示すようにキャッチャー14の第1爪部33に当接する。   Specifically, when the opened door 1 is closed to a predetermined opening angle, first, as shown in FIG. 13A, the catched portion 9 passes under the second claw portion 34 of the catcher 14 in the locked state. Then, as shown in FIG. 13 (b), it comes into contact with the first claw portion 33 of the catcher 14.

被キャッチ部9がさらに吊元側に移動すると、被キャッチ部9にてキャッチャー14の第1爪部33が吊元側に押圧され、これによりキャッチャー14の両被ガイド部38はロック部25からガイド部26に沿って下方に移動してレール部24に沿う状態となる。そして、このように両被ガイド部38がガイド部26に沿ってガイドされることで、キャッチャー14は図13(a)に示す待機姿勢から係合姿勢まで回動して図12(b)に示すように開口部36に被キャッチ部9が係合される。この係合姿勢にあるキャッチャー14の両突部33、34はベース13及びガイド部材17よりも下方に突出する。   When the catched portion 9 further moves to the suspension base side, the first claw portion 33 of the catcher 14 is pressed to the suspension base side by the catched portion 9, whereby both guided portions 38 of the catcher 14 are moved from the lock portion 25. It moves downward along the guide part 26 and is in a state along the rail part 24. Then, as both guided portions 38 are guided along the guide portion 26 in this manner, the catcher 14 rotates from the standby posture shown in FIG. As shown, the catched portion 9 is engaged with the opening 36. Both protrusions 33 and 34 of the catcher 14 in this engagement posture protrude below the base 13 and the guide member 17.

また、前述のように両被ガイド部38がロック部25からガイド部26を介してレール部24に至ると、両被ガイド部38のロック部25に対する係止が解除され、該移動部材28が弾性部材29の弾性力により吊元側に駆動される。   Further, as described above, when both guided portions 38 reach the rail portion 24 from the lock portion 25 via the guide portion 26, the locking of the both guided portions 38 to the lock portion 25 is released, and the moving member 28 is The elastic member 29 is driven to the suspension side by the elastic force.

このとき、キャッチャー14はその両被ガイド部38がレール部24に沿って走行し、このため前記係合姿勢を維持した状態で図12(c)や図13(d)に示すように係合した被キャッチ部9と共に左右方向の吊元側に移動する。また、この際、被キャッチ部9はドア1の閉方向の回動に伴い徐々に後方に移動してキャッチャー14の開口部36への挿入深さを深くしていく。   At this time, the catcher 14 is engaged as shown in FIGS. 12 (c) and 13 (d) in a state in which both guided portions 38 travel along the rail portion 24 and the engagement posture is maintained. It moves to the suspension side in the left-right direction together with the catched portion 9 that has been caught. At this time, the catched portion 9 gradually moves backward as the door 1 rotates in the closing direction, and the insertion depth of the catcher 14 into the opening 36 is increased.

そして、このように被キャッチ部9が吊元側に移動することで、所定開き角度まで閉じられたドア1が自動的に回動して閉状態となる。   And the to-be-caught part 9 moves to the suspension origin side in this way, and the door 1 closed to the predetermined opening angle will rotate automatically, and will be in a closed state.

逆に、前記閉じたドア1を人の手により開方向に回動させる。すると、被キャッチ部9は正面視で左右方向における手先側に移動し、ドア1が所定開き角度まで開かれたときにキャッチャー14との係合が外れる。   Conversely, the closed door 1 is rotated in the opening direction by a human hand. Then, the catched portion 9 moves to the hand side in the left-right direction when viewed from the front, and disengages from the catcher 14 when the door 1 is opened to a predetermined opening angle.

具体的には、閉じたドア1を所定開き角度まで開いたときには、手先側に移動する被キャッチ部9によりキャッチャー14の第2爪部34が手先側に押圧され、移動部材28がキャッチャー14と共に弾性部材29の弾性力に抗して手先側に移動する。このとき、キャッチャー14の両被ガイド部38はレール部24に沿って手先側に移動し、これによりキャッチャー14はドア1が係合姿勢を維持したまま手先側に移動する。   Specifically, when the closed door 1 is opened to a predetermined opening angle, the second claw portion 34 of the catcher 14 is pressed toward the hand side by the catched portion 9 that moves toward the hand side, and the moving member 28 moves together with the catcher 14. It moves to the hand side against the elastic force of the elastic member 29. At this time, both guided portions 38 of the catcher 14 move toward the hand side along the rail portion 24, whereby the catcher 14 moves toward the hand side while the door 1 maintains the engagement posture.

被キャッチ部9がさらに吊元側に移動してドア1が所定開き角度を越えたときには、キャッチャー14の両被ガイド部38はレール部24からガイド部26に至る。このように両被ガイド部38がレール部24から外れると、キャッチャー14は係合姿勢から待機姿勢までの範囲で回動自在となる。このため、さらに被キャッチ部9が吊元側に移動すると、両被ガイド部38はガイド部26に沿って上方に移動してロック部25に沿う状態となる。そして、このように両被ガイド部38がガイド部26にガイドされることで、キャッチャー14は係合姿勢から待機姿勢まで回動して図12(a)や図13(a)に示すロック状態となり、このとき、被キャッチ部9のキャッチャー14の開口部36に対する係合が外れる。この待機姿勢にあるキャッチャー14は第2爪部34の下端が第1爪部33の下端よりも上方に位置するため、ドア1をさらに開いた場合には、被キャッチ部9をキャッチャー14の第2爪部34の下側を通過させて支障なくドア1を開状態とすることができる。   When the catched portion 9 further moves to the suspension side and the door 1 exceeds a predetermined opening angle, both guided portions 38 of the catcher 14 reach the guide portion 26 from the rail portion 24. In this way, when the both guided portions 38 are disengaged from the rail portion 24, the catcher 14 is rotatable in the range from the engagement posture to the standby posture. For this reason, when the catched portion 9 further moves toward the suspension base, both guided portions 38 move upward along the guide portion 26 and become in a state along the lock portion 25. Then, the guided portions 38 are guided by the guide portions 26 in this way, so that the catcher 14 rotates from the engagement posture to the standby posture, and is in the locked state shown in FIGS. 12 (a) and 13 (a). At this time, the engagement of the catched portion 9 with the opening 36 of the catcher 14 is released. Since the lower end of the second claw portion 34 is positioned above the lower end of the first claw portion 33 of the catcher 14 in this standby posture, when the door 1 is further opened, the catched portion 9 of the catcher 14 is The door 1 can be opened without any trouble by passing the lower side of the two claw portions 34.

本例のドア引き込み装置は、キャッチャー14が上横枠7の長手方向に駆動してドア1を閉状態とする。このため、上横枠7に設けられる引き込み機構部10の前後幅を小さくして、平面視において上横枠7の前後幅内に引き込み機構部10をコンパクトに収めることができる。   In the door retracting apparatus of this example, the catcher 14 is driven in the longitudinal direction of the upper horizontal frame 7 to close the door 1. For this reason, the front-rear width of the retracting mechanism portion 10 provided in the upper horizontal frame 7 can be reduced, and the retracting mechanism portion 10 can be compactly accommodated within the front-rear width of the upper horizontal frame 7 in plan view.

また、前記ドア引き込み装置の被キャッチ部9はドア1の幅方向の位置を調節可能とされている。   Further, the catched portion 9 of the door retracting device can adjust the position of the door 1 in the width direction.

具体的には、図1や図2に示すように、被キャッチ部材6は、ドア1の背面に取り付けられるケース59と、ケース59に設けられた被キャッチ体56とで構成されており、被キャッチ体56の上端部から背方に向けて被キャッチ部9が突設されている。   Specifically, as shown in FIGS. 1 and 2, the member 6 to be caught is composed of a case 59 attached to the back surface of the door 1 and a body 56 to be caught provided on the case 59. A catched portion 9 projects from the upper end portion of the catch body 56 toward the back.

ケース59の左右両側にはドア1の幅方向に長い長孔54が形成されている。ケース59は各長孔54に左右方向にスライド自在に後方から挿通されたねじからなる固着具55をドア1に固着することにより、ドア1に取付けられる。なお、固着具55は釘で構成しても良いものとする。   Long holes 54 that are long in the width direction of the door 1 are formed on the left and right sides of the case 59. The case 59 is attached to the door 1 by fixing to the door 1 a fixing tool 55 made of a screw inserted through the long holes 54 from the rear so as to be slidable in the left-right direction. Note that the fixing tool 55 may be formed of a nail.

被キャッチ部材6をドア1に取り付ける場合、各固着具55の長孔54への左右方向における挿通位置を変更することにより、被キャッチ部材6のドア1の幅方向における取付位置を調節し、ひいては被キャッチ部9の左右方向の位置を調節できるようになっている。   When the member 6 to be caught is attached to the door 1, the attachment position of the catch member 6 in the width direction of the door 1 is adjusted by changing the insertion position in the left and right direction of the long hole 54 of each fixing tool 55. The position of the catched portion 9 in the left-right direction can be adjusted.

次に緩衝機構部11について説明する。図14及び図15に示す緩衝機構部11は、左右に長い緩衝機構部ベース40(以下、単にベース40と記載する)と、ベース40に設けられた動作変換機構及びショックアブソーバー43で構成されている。また、図2に示すようにドア1の背面における受部47に対応する位置にはドア回動の閉じ際に緩衝機構部の受部47に対しドア閉止方向への押圧力を伝える押圧作用部51が設けられており、該押圧作用部51と緩衝機構部11とでドア緩衝装置が構成されている。   Next, the buffer mechanism 11 will be described. 14 and 15 includes a buffer mechanism base 40 that is long to the left and right (hereinafter simply referred to as a base 40), and an operation conversion mechanism and a shock absorber 43 provided on the base 40. Yes. Further, as shown in FIG. 2, a pressing action portion that transmits a pressing force in the door closing direction to the receiving portion 47 of the buffer mechanism portion at the position corresponding to the receiving portion 47 on the back surface of the door 1 when the door rotation is closed. 51 is provided, and the pressing action part 51 and the shock-absorbing mechanism part 11 constitute a door shock-absorbing device.

図8(b)に示すように、ベース40は前方に開口する略溝型に形成され、その上面にベース13を載置し、ベース13の後縁片18をベース40の上面部にビス止めすることにより、ベース13に取り付けられる。ベース40は上横枠7の前後幅内に収められ、また、上横枠7に設けられた戸当たり5の前端よりも後方に配置される。   As shown in FIG. 8B, the base 40 is formed in a substantially groove shape that opens forward, the base 13 is placed on the upper surface thereof, and the rear edge piece 18 of the base 13 is screwed to the upper surface portion of the base 40. By doing so, it is attached to the base 13. The base 40 is housed within the front-rear width of the upper horizontal frame 7, and is disposed behind the front end of the door stop 5 provided on the upper horizontal frame 7.

動作変換機構は受部47の前後動作を受部47の前後ストロークよりも長いストロークとなる左右方向の動作に変換するものであり、作動体41と動作変換部42で構成されている。   The motion conversion mechanism converts the front-rear motion of the receiving portion 47 into a left-right motion that has a longer stroke than the front-rear stroke of the receiving portion 47, and includes an actuating body 41 and a motion converting portion 42.

作動体41は前方に開口するベース40に左右方向にスライド自在に収納されている。   The operating body 41 is accommodated in a base 40 that opens forward so as to be slidable in the left-right direction.

動作変換部42はドア1の閉じる際の回動動作に応じて作動体41を左右方向に動作させるものであり、ベース40に設けられた平面視く字状となるリンク機構部45と、リンク機構部45に設けられた受部47と、後述のねじりばね46で構成される。   The motion converting unit 42 moves the actuating body 41 in the left-right direction in accordance with the turning operation when the door 1 is closed, and includes a link mechanism unit 45 provided in the base 40 and having a square shape in plan view, and a link It comprises a receiving portion 47 provided in the mechanism portion 45 and a torsion spring 46 described later.

リンク機構部45は固定側リンク48と固定側リンク48よりも長い可動側リンク49とで構成され、固定側リンク48の一端はベース40に回動自在に連結され、可動側リンク49の一端は固定側リンク48の他端に回動自在に連結されている。可動側リンク49の他端は前記作動体41に連結されている。   The link mechanism unit 45 includes a fixed link 48 and a movable link 49 longer than the fixed link 48. One end of the fixed link 48 is rotatably connected to the base 40, and one end of the movable link 49 is The other end of the fixed side link 48 is rotatably connected. The other end of the movable side link 49 is connected to the operating body 41.

受部47は固定側リンク48と可動側リンク49の連結部分に回動自在に設けられている。   The receiving portion 47 is rotatably provided at a connecting portion between the fixed side link 48 and the movable side link 49.

リンク機構部45は、受部47が前後方向に動作することで、固定側リンク48がベース40に対して回動し、これにより図14のように固定側リンク48及び可動側リンク49が左右方向と略平行となって直線状に伸長した状態から、図16のように平面視く字状に折曲した状態までの範囲で変形可能となっている。このようにリンク機構部45を伸長状態や折曲状態に変更することで作動体41が左右方向に移動する。   In the link mechanism portion 45, the fixed portion link 48 rotates with respect to the base 40 by the receiving portion 47 operating in the front-rear direction, whereby the fixed side link 48 and the movable side link 49 are moved to the left and right as shown in FIG. It can be deformed in a range from a state of being substantially parallel to the direction and extending linearly to a state of being bent in a square shape in plan view as shown in FIG. Thus, the operating body 41 moves in the left-right direction by changing the link mechanism 45 to the extended state or the bent state.

固定側リンク48のベース40に枢支された端部とベース40の間には、伸長状態となったリンク機構部45の固定側リンク48を前方に回動する弾性力を付与するねじりばね46が配設されている。これによって、リンク機構部45は図16に示す折曲状態を維持するよう付勢される。   A torsion spring 46 for applying an elastic force to rotate the fixed side link 48 of the link mechanism 45 in the extended state between the end portion pivotally supported by the base 40 of the fixed side link 48 and the base 40. Is arranged. As a result, the link mechanism 45 is biased to maintain the bent state shown in FIG.

ショックアブソーバー43は左右方向に伸縮する伸縮式で且つ収縮時にのみ抵抗力を発生させるワンウェイ式のものであって、ベース13内に設けられ、該ショックアブソーバー43によって作動体41の左右方向の動作を緩衝する。   The shock absorber 43 is a telescopic type that expands and contracts in the left-right direction and is a one-way type that generates a resistance force only at the time of contraction. The shock absorber 43 is provided in the base 13, and the shock absorber 43 controls the operation body 41 in the left-right direction. Buffer.

今、リンク機構部45が図16に示す折曲状態にあり、且つ、キャッチャー14が前記ロック状態にあるときに、開いたドア1を人の手により閉方向に回動させる。すると、まず、ドア1が所定開き角度まで閉じられた時点で被キャッチ部9がキャッチャー14に係合され、前述の引き込み機構部10によるドア1の引き込みが開始される。   Now, when the link mechanism 45 is in the bent state shown in FIG. 16 and the catcher 14 is in the locked state, the opened door 1 is rotated in the closing direction by a human hand. Then, first, when the door 1 is closed to a predetermined opening angle, the catched portion 9 is engaged with the catcher 14, and the pull-in of the door 1 by the pull-in mechanism portion 10 described above is started.

そして、この後、前記引き込み機構部10によりドア1が少し閉方向に回動した時点で、ドア1の押圧作用部51が折曲状態にあるリンク機構部45に設けられた受部47に当たり、以後、ドア1が完全に閉じられるまで、引き込み機構部10の駆動力によって当該押圧作用部51が受部47を押圧して後方に移動させる。このとき、リンク機構部45は前記折曲状態から伸長状態へと変形していき、これにしたがって作動体41はショックアブソーバー43の抵抗に抗して手先側に移動するので、ドア1はゆるやかに閉状態となる。   After that, when the door 1 is slightly rotated in the closing direction by the retracting mechanism portion 10, the pressing action portion 51 of the door 1 hits the receiving portion 47 provided in the link mechanism portion 45 in the bent state, Thereafter, until the door 1 is completely closed, the pressing action portion 51 presses the receiving portion 47 by the driving force of the retracting mechanism portion 10 to move backward. At this time, the link mechanism 45 is deformed from the bent state to the extended state, and the operating body 41 moves to the hand side against the resistance of the shock absorber 43 accordingly, so that the door 1 is gently moved. Closed.

また、他例として、前記被キャッチ部9は図17及び図18に示すように被キャッチ体56の上端部から背方に突出する板状部60の一部で構成しても良い。   As another example, the catched portion 9 may be constituted by a part of a plate-like portion 60 that protrudes backward from the upper end portion of the catched body 56 as shown in FIGS. 17 and 18.

板状部60の左右方向の中央部には上下に貫通する挿入孔61が形成されており、板状部60の挿入孔61より吊元側の部分で被キャッチ部9が構成されている。   An insertion hole 61 penetrating in the vertical direction is formed in the central portion in the left-right direction of the plate-like portion 60, and the catched portion 9 is configured at a portion closer to the suspending side than the insertion hole 61 of the plate-like portion 60.

挿入孔61には、待機姿勢にあるキャッチャー14が係合姿勢に回動したときに、上方から第2爪部34が挿入されるようになっており、このように第2爪部34が挿入孔61に挿入された状態で前記引き込み機構により被キャッチ部9が吊元側に駆動されるようになっている。なお、本例においても、前記一例と同様に被キャッチ部9の左右方向の位置を調節できるようになっている。   When the catcher 14 in the standby posture rotates to the engagement posture, the second claw portion 34 is inserted into the insertion hole 61 from above, and thus the second claw portion 34 is inserted. In the state inserted in the hole 61, the to-be-caught part 9 is driven to the suspension side by the pull-in mechanism. Also in this example, the position of the catched portion 9 in the left-right direction can be adjusted in the same manner as in the above example.

このように、本発明のドア引き込み装置にあっては、被キャッチ部9の左右方向の位置を調節することができ、このため、被キャッチ部9をキャッチャー14に確実に係合させることができる。   Thus, in the door retracting device of the present invention, the position of the catched portion 9 in the left-right direction can be adjusted, and therefore the catched portion 9 can be reliably engaged with the catcher 14. .

また、前記ドア引き込み装置によるドア1の引き込み開始位置を調節することも可能となる。すなわち、図18(a)に示すように、被キャッチ部9を図18(b)に示す標準位置よりも吊元側に配置した場合には、被キャッチ部9がキャッチャー14に係合される位置、すなわち引き込み機構による引き込みが開始される位置のドア1の開き角度αを小さくすることができる。逆に図18(c)に示すように被キャッチ部9を手先側に配置した場合には、被キャッチ部9がキャッチャー14に係合される位置のドア1の開き角度αを大きくすることができる。したがって、ドア幅やドアの重量、使用方法等に応じてドア引き込み装置によるドア1の引き込み開始位置を調節することができる。   Moreover, it becomes possible to adjust the pull-in start position of the door 1 by the door pull-in device. That is, as shown in FIG. 18A, when the catched portion 9 is arranged on the suspending side from the standard position shown in FIG. 18B, the catched portion 9 is engaged with the catcher 14. The opening angle α of the door 1 at the position, that is, the position where the drawing by the drawing mechanism is started can be reduced. Conversely, when the catched portion 9 is arranged on the hand side as shown in FIG. 18C, the opening angle α of the door 1 at a position where the catched portion 9 is engaged with the catcher 14 may be increased. it can. Therefore, the pull-in start position of the door 1 by the door pull-in device can be adjusted according to the door width, door weight, usage method, and the like.

なお、前記各例ではドア1を閉じた状態ではドア1がドア枠2内に収められるものとしたが、閉じたドア1は後部のみがドア枠2内に収められるものであっても良いし、ドア枠2の前方に位置するものであって良い。   In each of the above examples, the door 1 is stored in the door frame 2 when the door 1 is closed. However, the closed door 1 may be configured such that only the rear portion is stored in the door frame 2. It may be located in front of the door frame 2.

また、前記各例では、上横枠7に前記緩衝機構部11を設けると共にドア1の上端部に前記押圧作用部51を設けたが、逆に、ドア1の上端部に前記緩衝機構部11を設けると共に上横枠7に前記押圧作用部51を設けても良い。また、ドア緩衝装置を設けずに、ドア引き込み装置のみを設けても良い。   In each of the above examples, the buffer mechanism portion 11 is provided on the upper horizontal frame 7 and the pressing action portion 51 is provided on the upper end portion of the door 1. Conversely, the buffer mechanism portion 11 is provided on the upper end portion of the door 1. And the pressing action portion 51 may be provided on the upper horizontal frame 7. Moreover, you may provide only a door drawing-in apparatus, without providing a door shock absorber.
