Description

本発明は、レールに懸吊されて走行するランナに取付られた戸を開閉する際に、開閉速度を減少させて静かに閉まるようにした戸の制動装置に関する。   TECHNICAL FIELD The present invention relates to a door braking device in which when a door attached to a runner suspended from a rail is opened and closed, the opening and closing speed is reduced and the door is quietly closed.

レールに車輪を備えたランナを介して引戸が走行自在に懸吊される上吊式の引戸が提案されている。しかし、このような上吊式の引戸においては、引戸を円滑にかつ軽快に動かすことができる反面、勢いよく閉めると、引戸が縦枠に衝突し、その反動で跳ね返ることがあった。   An upper suspension type sliding door is proposed in which a sliding door is suspended so as to be able to travel through a runner having wheels on a rail. However, in such a hanging type sliding door, the sliding door can be moved smoothly and lightly, but when it is closed with force, the sliding door collides with the vertical frame and rebounds due to the reaction.

そこで、図7に示すように、レール101の下端部における突条104を転動する車輪108,109を備えたランナ本体100、該ランナ本体100に接触しないようにレール101内に突出して設けられた制動付与部材123、該制動付与部材123に当接すると制動力を発生する制動体120を備えて、引戸Dが縦枠Sに当接する直前に制動力を発生させて引戸Dの跳ね返りを防止する構成が提案されている(特許文献1参照)。   Therefore, as shown in FIG. 7, a runner main body 100 including wheels 108 and 109 that roll the protrusions 104 at the lower end of the rail 101, and is provided so as to protrude into the rail 101 so as not to contact the runner main body 100. The brake applying member 123 and the brake body 120 that generates a braking force when coming into contact with the brake applying member 123 are provided, and the braking force is generated immediately before the sliding door D comes into contact with the vertical frame S to prevent the sliding door D from being rebounded. The structure which performs is proposed (refer patent document 1).

この制動体120は、ランナ本体100の一端に連結して固着されて、回動自在に支持された中空ブロック121、該中空ブロック121内に設けられた図示しないバネにより飛び出すように付勢された当接部143、中空ブロック121に設けられて突条104に当接するブレーキゴム142を備えている。なお、中空ブロック121が自由に回転しないように、制動体回転規制部124が設けられている。   The braking body 120 is connected and fixed to one end of the runner main body 100, and is urged so as to pop out by a hollow block 121 rotatably supported and a spring (not shown) provided in the hollow block 121. A brake rubber 142 is provided on the contact portion 143 and the hollow block 121 and contacts the protrusion 104. A braking body rotation restricting portion 124 is provided so that the hollow block 121 does not rotate freely.

そして、図7(a)に示すように、f1の方向に戸Dが閉動作すると、閉止寸前の位置で当接部143が制動付与部材123に当接する。当接部143は制動付与部材123の方向に付勢しているため、当該当接部143は制動付与部材123に当接するとバネの力に抗して中空ブロック121内に押し込まれる。その後、当接部143は図7(b)に示すような状態で、制動付与部材123に摺擦しながら動き、このときの摩擦力が制動力として作用する。
特開平11−148269号公報
Then, as shown in FIG. 7A, when the door D is closed in the direction of f1, the contact portion 143 contacts the brake applying member 123 at a position just before the closing. Since the contact portion 143 is biased in the direction of the brake applying member 123, when the contact portion 143 contacts the brake applying member 123, the contact portion 143 is pushed into the hollow block 121 against the force of the spring. Thereafter, the contact portion 143 moves while sliding on the braking applying member 123 in the state shown in FIG. 7B, and the frictional force at this time acts as a braking force.
JP-A-11-148269

しかしながら、上記制動装置においては、f2の方向に引戸Dが開動作する際に、当接部143と制動付与部材123との当接が解除されるが、このとき制動体120が踊り、異音を発生する問題があった。   However, in the braking device, when the sliding door D opens in the direction of f2, the contact between the contact portion 143 and the brake applying member 123 is released. There was a problem that occurred.

このことを図8を参照して説明する。図8は制動体120部分を拡大して示した図で、引戸Dがf1の方向に動いているときには、ブレーキゴム142が突条104に当接するまで、制動体120は回転軸Pを中心としてω1の方向に回転する。このとき、当接部143は、図8(a)に示すように、バネに抗して中空ブロック121内に押込まれて、中空ブロック121の作用面Mと接している。   This will be described with reference to FIG. FIG. 8 is an enlarged view of the brake body 120. When the sliding door D moves in the direction of f1, the brake body 120 is centered on the rotation axis P until the brake rubber 142 abuts against the protrusion 104. It rotates in the direction of ω1. At this time, as shown in FIG. 8A, the contact portion 143 is pushed into the hollow block 121 against the spring and is in contact with the working surface M of the hollow block 121.

ところが、引戸Dをf2の方向に動かすと、当接部143はf1の方向に力を受けているため、制動体120は回転軸Pを中心にω2の方向に回転するようになる。   However, when the sliding door D is moved in the direction f2, the abutting portion 143 receives a force in the direction f1, so that the braking body 120 rotates about the rotation axis P in the direction ω2.

水平面に対する制動体120の角度が小さくなると、当接部143が制動付与部材123の表面を滑り始めるようになり、このとき残っているバネの力で制動体120は勢いよく回転してしまい、制動体回転規制部124に当接して、図8(b)に示す状態となって上記異音が発生する。   When the angle of the braking body 120 with respect to the horizontal plane decreases, the contact portion 143 starts to slide on the surface of the braking applying member 123, and the braking body 120 rotates vigorously by the remaining spring force at this time. The abnormal noise is generated by coming into contact with the body rotation restricting portion 124 and in the state shown in FIG.

無論、このような異音は、機構上何ら問題となる音ではないが、利用者に不安を与えたり、商品品質を低下させてしまう不都合がある。   Of course, such an abnormal noise is not a sound that causes any problem in terms of mechanism, but has a disadvantage that it gives the user anxiety and deteriorates the product quality.

そこで、本発明は、戸を開く際等においても異音を発生しないようにした高品質な制動装置を提供することを目的とする。   Accordingly, an object of the present invention is to provide a high-quality braking device that does not generate abnormal noise even when the door is opened.

上記課題を解決すべく、請求項1に係る発明は、下方に開口した断面概略C字状をなすレールの下端縁部内側を転動して走行するランナと、該ランナに連結されると共に戸に埋込み固定される取付部と、該戸の動きに応じて制動力を発生する制動部とを備える戸の制動装置において、前記制動部は制動力付与部材と制動部本体とからなり、前記制動力付与部材は、端部が薄くて中央部が所定厚みを有し、戸が閉まる直前のレールの内側天面の所定位置に固着され、前記制動部本体は、前記制動力付与部材に向かって当接して摺動する当接部と、該当接部を収納する制動部ケースと、該制動部ケースに収納され前記当接部を制動部ケースから押出すように付勢するバネと、前記制動部ケースの左右の側面に突出して設けられたガイドリブと、前記ランナの後端に形成されて前記制動部ケースが上下動すると同時に前後動できるようにして収容する制動部収納穴と、該制動部収納穴の側壁に形成されて前記ガイドリブが遊嵌する長穴であって、戸が閉まる方向に下るように傾斜したガイド傾斜穴とを備え、
閉動作に際しては、戸が閉まる直前に制動力付与部材の端部に制動部本体の当接部が当接し、閉動作に応じて制動部ケースがガイドリブを介してガイド傾斜穴に沿って上動して上端に達し、制動力付与部材の中央部の厚みに応じて制動部本体の当接部の受けるバネからの力を増大させながら前記制動力付与部材に摺動して制動力が増大され、
開動作に際しては、ガイド傾斜穴に沿って制動部ケースがガイドリブを介して下動してガイド傾斜穴の下端に達し、制動力付与部材の中央部の厚みに対して制動部本体の当接部の受けるバネの力が減少されたまま摺動し、制動力付与部材の端部で制動部本体の当接部との当接が解除されることを特徴とする。
In order to solve the above-mentioned problems, the invention according to claim 1 is directed to a runner that rolls and runs inside the lower end edge of a rail having a substantially C-shaped cross section that opens downward, and is connected to the runner and doors. In a door braking device comprising a mounting part embedded and fixed in a door and a braking part that generates a braking force in accordance with the movement of the door, the braking part comprises a braking force applying member and a braking part main body, The power applying member has a thin end portion and a central portion having a predetermined thickness, and is fixed to a predetermined position on the inner top surface of the rail immediately before the door is closed, and the braking portion main body is directed toward the braking force applying member. A contact portion that contacts and slides, a brake portion case that houses the contact portion, a spring that is housed in the brake portion case and urges the contact portion to be pushed out of the brake portion case, and the brake Guide ribs protruding from the left and right sides of the front case, and the front A brake part storage hole formed at the rear end of the runner to receive the brake part case so that the brake case moves up and down at the same time, and a long hole formed in a side wall of the brake part storage hole and into which the guide rib is loosely fitted. And a guide inclined hole inclined so as to descend in the direction in which the door is closed,
In the closing operation, the abutting portion of the braking portion main body abuts on the end portion of the braking force applying member immediately before the door is closed, and the braking portion case moves upward along the guide inclined hole via the guide rib according to the closing operation. The braking force is increased by sliding on the braking force applying member while increasing the force from the spring received by the contact portion of the braking unit main body according to the thickness of the central portion of the braking force applying member. ,
In the opening operation, the brake part case moves down along the guide inclined hole via the guide rib to reach the lower end of the guide inclined hole, and the contact part of the brake part main body with respect to the thickness of the central part of the braking force applying member The sliding force is reduced while the force of the spring received is reduced, and the contact with the contact portion of the braking portion main body is released at the end of the braking force applying member .

これにより、例えば戸を開く際には開動作に応じて、制動部ケースが戸が閉まる方向に下がるように傾斜したガイド傾斜穴にガイドされて下動するため、当接部が制動力付与部材に当接する当接力が徐々に減少して、当接解除するようになり、制動部本体が踊り、異音を発生するような事態を防止することが可能になる。 Thus, for example, when opening the door , the abutting portion is guided by the guide inclined hole inclined so as to be lowered in the direction in which the door is closed in accordance with the opening operation. The abutting force that abuts on the heel gradually decreases and the abutment is released, so that it is possible to prevent a situation in which the brake unit body dances and abnormal noise is generated.

また、請求項2に係る発明は、制動部ケースはランナの制動部収納穴内を上下動すると同時に前後動できる大きさに形成され、上下動と前後動はガイド傾斜穴に遊嵌するガイドリブにより規制されることを特徴とする。 In the invention according to claim 2, the brake part case is formed to have a size capable of moving back and forth at the same time as moving up and down in the brake part receiving hole of the runner, and the vertical and forward and backward movements are regulated by guide ribs that are loosely fitted into the guide inclined holes. It is characterized by being.

これにより、制動部ケースがガイドリブを介してガイド傾斜穴に規制されて移動する。Accordingly, the brake part case moves while being regulated by the guide inclined hole via the guide rib.

本発明によれば、制動部をレールの内側天面の所定位置に固着される制動力付与部材と、ランナに設けられて、閉じられる戸が所定位置に達すると制動力付与部材に当接し、その後の閉動に応じて当該当接力を増大させ、該当接力が所定値に達すると制動力付与部材との摺擦を開始して一定の制動力を発揮し、戸を開く場合には制動力が減少するように当接力を減少させ、戸が所定位置に達すると該制動力付与部材との当接が解除するように動作する制動部本体とにより構成したので、例えば戸を開く際には開動作に応じて、制動部本体と制動力付与部材との当接力が徐々に減少して当接解除するようになり、制動部本体が踊り、異音を発生するような事態を防止することが可能になる。   According to the present invention, the braking force applying member fixed to the predetermined position on the inner top surface of the rail and the runner provided on the runner abuts the braking force applying member when the door to be closed reaches the predetermined position, The contact force is increased in accordance with the subsequent closing movement, and when the contact force reaches a predetermined value, the friction with the braking force application member starts to exert a certain braking force, and when the door is opened, the braking force When the door is opened, for example, when the door is opened, the braking force is reduced so that the contact force is reduced so that the contact with the braking force applying member is released when the door reaches a predetermined position. In accordance with the opening operation, the contact force between the braking unit body and the braking force applying member gradually decreases to release the contact, preventing the braking unit body from dancing and generating abnormal noise. Is possible.

本発明の実施の形態を図を参照して説明する。図1は、本発明に係る引戸に適用した制動装置の斜視図を示し、図2は制動部の外観斜視図、図3は制動装置の断面図を示している。なお、本実施例においては、上吊式引戸を例に説明するが、本発明はこれに限定されるものではなく、上吊式の扉体であれば適用可能であり折戸であっても良い。   Embodiments of the present invention will be described with reference to the drawings. 1 is a perspective view of a braking device applied to a sliding door according to the present invention, FIG. 2 is an external perspective view of a braking portion, and FIG. 3 is a cross-sectional view of the braking device. In the present embodiment, the upper suspension type sliding door will be described as an example. However, the present invention is not limited to this, and may be applied to any upper suspension type door body and may be a folding door.

制動装置10は、上枠であって戸Dが閉まる端部近傍に取付られるレール11にガイドされて移動するようになっており、このレール11の下端縁部が互いに対向するように折り曲げられてランナ走行枠12をなす断面視概略C字状に形成されている。   The braking device 10 is moved by being guided by a rail 11 which is an upper frame and is attached in the vicinity of an end portion where the door D is closed, and the lower end edges of the rail 11 are bent so as to face each other. The runner travel frame 12 is formed in a substantially C shape in a sectional view.

この制動装置10は、ランナ13、制動部14、取付部15を主要構成としている。なお、ランナ13、制動部14及び取付部15は一体化されて、該取付部15を戸Dの上端に埋め込み固定することで、これらを戸Dに取付ることができるようになっている。一方、制動部14における制動付与部材16はレール11の内側天面にビス止めして固着されて、制動部14と当接することにより制動力を発生するようになっている。   The braking device 10 has a runner 13, a braking portion 14, and an attachment portion 15 as main components. The runner 13, the braking portion 14, and the attachment portion 15 are integrated, and the attachment portion 15 is embedded and fixed to the upper end of the door D so that they can be attached to the door D. On the other hand, the braking applying member 16 in the braking portion 14 is fixed to the inner top surface of the rail 11 with screws, and a braking force is generated by contacting the braking portion 14.

以下各部を詳細に説明する。ランナ13は、ローラ対からなる走行ローラ21を2対備え、これら2対の走行ローラ21のローラ軸24がランナ基台23に挿通されて回動自在に回転できるようになっている。2対の走行ローラ21の中間位置には、吊軸22がランナ基台23を鉛直方向に挿通して設けられ、その先端部分に取付部15が挿嵌している。
また、吊軸22の頂部には座金31が装着され、先端部は取付部15における昇降ピン32により昇降板33に連結されている。
Each part will be described in detail below. The runner 13 includes two pairs of traveling rollers 21 including a pair of rollers. The roller shafts 24 of the two pairs of traveling rollers 21 are inserted into the runner base 23 so as to be rotatable. At a middle position between the two pairs of traveling rollers 21, a suspension shaft 22 is provided through the runner base 23 in the vertical direction, and a mounting portion 15 is inserted into a tip portion thereof.
A washer 31 is mounted on the top of the suspension shaft 22, and the tip is connected to the lifting plate 33 by the lifting pins 32 in the mounting portion 15.

ランナ基台23の後端(戸Dの開方向側の端部)には、上下に開口した制動部収納穴29が形成され、その対向する左右の側面にはガイド傾斜穴34が形成されている。このガイド傾斜穴34は、戸Dが閉まる方向に下るように傾斜した穴である。   At the rear end of the runner base 23 (the end portion on the opening direction side of the door D), a braking portion receiving hole 29 opened up and down is formed, and a guide inclined hole 34 is formed on the left and right side surfaces facing each other. Yes. The guide inclined hole 34 is a hole inclined so as to descend in the direction in which the door D is closed.

制動部14は、当接部35、該当接部35を収納して制動部14の外観をなす制動部ケース36、制動部ケース36内に配設されて当接部35を制動部ケース36から押し出すように付勢するバネ37、制動部ケース36に立設されたガイドリブ38等からなる制動部本体と、制動付与部材16とにより形成されている。   The brake unit 14 accommodates the contact part 35, the corresponding contact part 35, and the brake part case 36 that forms the appearance of the brake part 14. The brake part 14 is disposed in the brake part case 36 and removes the contact part 35 from the brake part case 36. It is formed of a spring 37 that urges it to be pushed out, a brake part main body including a guide rib 38 erected on the brake part case 36, and the brake applying member 16.

なお、当接部35の頂部39は、図1〜図3に示すように、戸Dの開閉方向の端縁部が丸く面取りされ、当該当接部35が制動部ケース36から抜出ないように、抜止ピン41が当接部35を挿通して設けられ、その端部が制動部ケース36に係合している。   As shown in FIGS. 1 to 3, the top 39 of the contact portion 35 is rounded at the edge in the opening / closing direction of the door D so that the contact portion 35 is not pulled out from the brake portion case 36. Further, a retaining pin 41 is provided through the abutting portion 35, and an end portion thereof is engaged with the braking portion case 36.

制動付与部材16は、端部の厚みが薄く、中央部が所定の厚みを有したステック状部材で、両端部にビス40等を用いて当該制動付与部材16をレール11又は上枠に取付るためのビス穴が形成されている。   The brake applying member 16 is a stick-shaped member having a thin end portion and a central portion having a predetermined thickness, and the brake applying member 16 is attached to the rail 11 or the upper frame using screws 40 or the like at both ends. Screw holes are formed.

また、当接部35又は制動付与部材16の少なくとも1は、摩擦材により形成されて、当接部35と制動付与部材16とが摺動する際に効果的に所望の制動力が発現するようになっている。   Further, at least one of the contact portion 35 or the brake applying member 16 is formed of a friction material so that a desired braking force is effectively expressed when the contact portion 35 and the brake applying member 16 slide. It has become.

制動付与部材16の取付位置は、戸Dが閉まる直前に制動部14における当接部35が制動付与部材16に当接する位置とし、かかる位置は、要求される制動量に応じて、バネ37の力、当接部35と制動付与部材16の摩擦係数及びその当接面積、当接部35と制動付与部材16の当接摺動距離等を戸Dの重量や利用者が戸Dを閉める際に加える力を勘案して設定する。   The mounting position of the brake applying member 16 is a position where the contact portion 35 of the braking portion 14 contacts the brake applying member 16 immediately before the door D is closed, and this position is determined by the spring 37 according to the required braking amount. Force, the friction coefficient of the contact portion 35 and the brake applying member 16 and the contact area thereof, the contact sliding distance between the contact portion 35 and the brake applying member 16, etc. Set in consideration of the force applied to.

そして、制動部ケース36は制動部収納穴29により適宜小さい大きさに形成されて、当該制動部収納穴29内を上下動すると共に前後動できるようになっており、該運動はガイド傾斜穴34に遊嵌するガイドリブ38により規制されるようになっている。   The brake part case 36 is formed in a suitably small size by the brake part storage hole 29 so that it can move up and down in the brake part storage hole 29 and move back and forth. It is regulated by a guide rib 38 that fits freely.

従って、ガイドリブ38が制動部ケース36に固着されガイド傾斜穴34に遊嵌するようになっているため、制動部14が戸Dを開く方向に動くと、その頂部39は上昇し、閉る方向に動くと頂部39は下降するように動くようになる。   Therefore, since the guide rib 38 is fixed to the brake part case 36 and is loosely fitted in the guide inclined hole 34, when the brake part 14 moves in the direction to open the door D, the top part 39 rises and closes. When moved to the top, the top 39 moves downward.

取付部15は吊軸22が挿通する吊軸挿通穴43、昇降板33が収納される昇降板収納穴44、該昇降板33を水平方向に進退させる高さ調整ネジ45、取付部15と吊軸22との垂線方向の傾きを調整するために吊軸22が挿通する水平面断面が菱形形状に形成された2の水平固定具47、該水平固定具47を水平方向に進退させる左右調整ネジ46等を有して、そのケースをビス48で戸Dに取付けられるようになっている。そして、昇降ピン32は昇降板33に形成された昇降用長穴49に遊嵌している。   The mounting portion 15 includes a suspension shaft insertion hole 43 through which the suspension shaft 22 is inserted, a lifting plate storage hole 44 in which the lifting plate 33 is stored, a height adjusting screw 45 for moving the lifting plate 33 back and forth in the horizontal direction, and the mounting portion 15 and the suspension. In order to adjust the inclination in the direction perpendicular to the shaft 22, two horizontal fixtures 47 in which the horizontal plane section through which the suspension shaft 22 is inserted is formed in a rhombus shape, and a left and right adjustment screw 46 for moving the horizontal fixture 47 back and forth in the horizontal direction Etc., and the case can be attached to the door D with a screw 48. The elevating pins 32 are loosely fitted in elevating elongate holes 49 formed in the elevating plate 33.

次に、このような構成の制動装置10を取付る際の手順を説明する。制動装置10を取付る際には、予め戸Dの上端部に取付部15を収納する溝51を形成しておく。そして、レール11にランナ13を装着し、当該レール11を上枠に固定する。その後、制動を開始する位置を決定し、この位置に制動付与部材16の端部を位置合わせして当該制動付与部材16をビス30により固定する。   Next, a procedure for attaching the braking device 10 having such a configuration will be described. When attaching the braking device 10, a groove 51 for accommodating the attaching portion 15 is formed in the upper end portion of the door D in advance. Then, the runner 13 is mounted on the rail 11, and the rail 11 is fixed to the upper frame. Then, the position where braking is started is determined, the end of the braking application member 16 is aligned with this position, and the braking application member 16 is fixed with screws 30.

そして、ランナ13から懸吊されている取付部15を戸Dに形成されている溝51に挿入し、ビス止めして固定する。このとき、ランナ13と取付部15とは吊軸22により回動自在に連結されているため、例えば取付部15を戸Dに固定する際に戸板面に対して左右方向にずれている場合があるが、このような場合は左右調整ネジ46を回して調整する。   And the attaching part 15 suspended from the runner 13 is inserted in the groove | channel 51 currently formed in the door D, and is screwed and fixed. At this time, since the runner 13 and the attachment portion 15 are rotatably connected by the suspension shaft 22, for example, when the attachment portion 15 is fixed to the door D, the runner 13 and the attachment portion 15 may be displaced in the left-right direction with respect to the door plate surface. In such a case, the left / right adjustment screw 46 is turned to adjust.

戸Dを取付けた後は、取付部15に設けられている高さ調整ネジ45を回転させることにより戸Dの高さ調整を行う。高さ調整ネジ45を回転させると、当該高さ調整ネジ45に螺合している昇降板33が進退する。例えば図3において、昇降板33が右側に動くと、昇降ピン32は昇降用長穴49にガイドされて上動し、該昇降ピン32の動きに従動して吊軸22が上動する。戸Dはレール11に懸吊された状態であるので、吊軸22が上動することは、戸Dが下降することを意味している。   After the door D is attached, the height of the door D is adjusted by rotating the height adjusting screw 45 provided in the attachment portion 15. When the height adjustment screw 45 is rotated, the elevating plate 33 screwed into the height adjustment screw 45 advances and retreats. For example, in FIG. 3, when the elevating plate 33 moves to the right side, the elevating pin 32 is guided by the elevating elongate hole 49 and moves upward, and the suspension shaft 22 moves up following the movement of the elevating pin 32. Since the door D is suspended from the rail 11, the upward movement of the suspension shaft 22 means that the door D is lowered.

次に、このような構成の制動装置10の動作を図4〜図6を参照して説明する。図4及び図5は、戸Dを閉める際の様子を示し、図4は当接部35が制動付与部材16に接触するまで、図5は当接部35が制動付与部材16に当接摺動して戸Dが完全に閉まった状態までを示している。また、図6は、戸Dを開く際の様子を示している。   Next, the operation of the braking apparatus 10 having such a configuration will be described with reference to FIGS. 4 and 5 show a state when the door D is closed. FIG. 4 shows that the contact portion 35 contacts the brake applying member 16 until the contact portion 35 contacts the brake applying member 16. It shows a state where the door D is moved and completely closed. FIG. 6 shows a state when the door D is opened.

戸Dを閉め始めると、そのときの力によりランナ13がランナ走行枠12の上を走行する(図4(a))。そして、戸Dが完全に閉まる直前まで達すると、当接部35が制動付与部材16に当接するようになる(図4(b))。このとき制動部14の位置は、後述するように、戸Dを開けるときの動作によりガイドリブ38がガイド傾斜穴34の左端に当接した状態となっている。   When the door D starts to be closed, the runner 13 travels on the runner travel frame 12 by the force at that time (FIG. 4A). Then, when reaching just before the door D is completely closed, the contact portion 35 comes into contact with the braking application member 16 (FIG. 4B). At this time, the position of the braking portion 14 is in a state where the guide rib 38 is in contact with the left end of the guide inclined hole 34 by the operation when opening the door D, as will be described later.

その後、戸Dが閉まる方向に動くと、制動付与部材16の作用面Sより当接部35の頂部39の方が適宜高い位置に設定されているので、当接部35は制動付与部材16から逃げるように、戸Dを開ける方向に動き、この動きに伴いガイドリブ38はガイド傾斜穴34を昇るようになる(図4(c))。   Thereafter, when the door D moves in the closing direction, the top portion 39 of the contact portion 35 is set to a position that is appropriately higher than the action surface S of the brake applying member 16. In order to escape, it moves to the direction which opens the door D, and the guide rib 38 comes to rise up the guide inclined hole 34 with this movement (FIG.4 (c)).

図4(c)の状態では、まだ制動力は発生していないが、さらに戸Dが閉まる方向に動くと、ガイドリブ38はガイド傾斜穴34の右端に達し(図5(a)、これ以降は当接部35は制動付与部材16から逃げることができないので、当接部35の頂部39が制動付与部材16の傾斜部Nと摺動しながら(図5(b))、バネ37に抗して制動部ケース36内に押し込まれる。   In the state of FIG. 4C, no braking force is generated yet, but when the door D further moves in the closing direction, the guide rib 38 reaches the right end of the guide inclined hole 34 (FIG. 5A), and thereafter Since the contact portion 35 cannot escape from the brake applying member 16, the top portion 39 of the contact portion 35 slides against the inclined portion N of the brake applying member 16 (FIG. 5B) and resists the spring 37. To be pushed into the brake part case 36.

そして、頂部39が制動付与部材16の下に潜り込んだ状態となり、この状態ではバネ37により付勢された当接部35の頂部39が制動付与部材16の作用面Mと摺動するので、そのときの摩擦が戸Dの動きを止める制動力として発現する。   Then, the top portion 39 is in a state of being submerged under the brake applying member 16, and in this state, the top portion 39 of the contact portion 35 urged by the spring 37 slides on the working surface M of the brake applying member 16, so that The friction at the time appears as a braking force that stops the movement of the door D.

戸Dはこの制動力により速度を落としながら閉まるようになるため、戸Dが完全に閉まって(図5(c))、木口が縦枠に当接して跳ね返ることが防止することが可能になる。   Since the door D is closed while reducing the speed by this braking force, the door D is completely closed (FIG. 5C), and it is possible to prevent the butt from bouncing against the vertical frame. .

次に、戸Dを開けるときは、図6に示すような動作手順を経る。先ず、図6(a)に示す状態からユーザが戸Dを開けると、制動部14のガイドリブ38はガイド傾斜穴34を下るように動く(図6(b))。これは、一般に静止摩擦係数の方が動摩擦係数より大きいこと、及びガイドリブ38がガイド傾斜穴34を下ることはバネ37からの力が小さくなる方向であることによる。   Next, when opening the door D, an operation procedure as shown in FIG. 6 is performed. First, when the user opens the door D from the state shown in FIG. 6A, the guide rib 38 of the braking portion 14 moves down the guide inclined hole 34 (FIG. 6B). This is because, in general, the static friction coefficient is larger than the dynamic friction coefficient, and the fact that the guide rib 38 goes down the guide inclined hole 34 is a direction in which the force from the spring 37 becomes smaller.

従って、ガイドリブ38がガイド傾斜穴34を下っている時は、制動付与部材16に対する制動部14の位置が変化しないでランナ13(即ち、戸D)の位置が変化していることになり、この動きに伴い当接部35の頂部と制動付与部材16との当接力が減少する。即ち、制動力が小さくなる。   Therefore, when the guide rib 38 is below the guide inclined hole 34, the position of the runner 13 (that is, the door D) is changed without changing the position of the braking portion 14 with respect to the braking applying member 16. With the movement, the contact force between the top of the contact portion 35 and the braking application member 16 decreases. That is, the braking force is reduced.

そして、ガイドリブ38がガイド傾斜穴34の左端に当接すると、その後は、制動部14はランナ13と共に動き、当接部35と制動付与部材16との当接が解除される状態となり制動力が解消して(図6(c))、自由走行が可能となる(図6(d))。   Then, when the guide rib 38 abuts against the left end of the guide inclined hole 34, the braking portion 14 moves together with the runner 13 so that the abutment between the abutment portion 35 and the brake applying member 16 is released, and the braking force is increased. This is eliminated (FIG. 6 (c)), and free running is possible (FIG. 6 (d)).

このように、制動部14が戸Dも開閉方向に応じて上下動し、開く際には制動力が徐々に減少し、閉じる際には徐々に増加するため、従来のように制動部14が踊り、異音を発生させる事態が防止できるようになる。   As described above, since the braking unit 14 moves up and down in accordance with the opening / closing direction of the door D, the braking force gradually decreases when the door D is opened and gradually increases when the door D is closed. It will be possible to prevent situations where dances and abnormal sounds occur.
