本発明は、引戸の閉扉速度を減速させる制動装置を備えた引戸装置に関するものである。   The present invention relates to a sliding door device including a braking device that reduces the closing speed of the sliding door.

引戸装置において、引戸の閉扉動作が自動的に行われる自閉式のものは既に知られている。この種の引戸装置としては、引戸と所定位置に固定された部材（引戸枠）との間に、閉じ力発生手段が設けられ、開放された引戸が前記閉じ力発生手段の付勢力により自動的に閉扉させるように構成したものである。なお、閉じ力発生手段としては、閉扉方向に付勢するぜんまいばねやコイルばね、ウェイトの重量により引戸を閉扉方向に引っ張るものや、引戸に設けた車輪を、閉扉方向側を少し下方に傾斜させたレール上に転動自在に載置して、引戸の自重により自動的に閉扉させたものが公知である。   As the sliding door device, a self-closing type in which the sliding door is automatically closed is already known. In this type of sliding door device, a closing force generating means is provided between the sliding door and a member (sliding door frame) fixed at a predetermined position, and the opened sliding door is automatically operated by the urging force of the closing force generating means. The door is configured to be closed. As the closing force generating means, the mainspring spring, coil spring, and the weight of the weight that pulls the sliding door in the closing direction, and the wheel provided on the sliding door are tilted slightly downward on the closing direction side. It is known that it is mounted on a rail so as to be able to roll and is automatically closed by its own weight.

このような引戸装置においては、引戸が閉じる際に引戸枠の竪枠などの部材に強く当接した衝撃により、引戸や閉扉箇所の部材などを損傷したり騒音を生じないようにするために、制動装置が設けられている。かかる制動装置は、引戸側に固定される制動手段の入力軸に外嵌されたピニオンギアと、該ピニオンギアに噛合してピニオンギアに所定のトルクを付与すべく、引戸枠側に固定されたラックとを備えている。   In such a sliding door device, when the sliding door is closed, in order not to damage the sliding door or the member of the closed portion or to make noise due to the impact strongly contacted with the member such as the frame of the sliding door frame, A braking device is provided. Such a braking device is fixed to the sliding door frame side so as to mesh with the pinion gear externally fitted to the input shaft of the braking means fixed to the sliding door side and apply a predetermined torque to the pinion gear. With a rack.

この引戸装置によれば、引戸が完全に閉扉される前にラックにピニオンギアが噛合して入力軸が制動されながら回転されることにより引戸の閉扉動作が制動されるため、引戸が閉扉する際に閉扉箇所の部材に強く当接することはなくなって、引戸や閉扉箇所の部材などを損傷したり騒音を生じたりすることを防止できる。（下記特許文献１参照）
特開２００２−５４３４８号公報 According to this sliding door device, since the pinion gear meshes with the rack before the sliding door is completely closed and the input shaft is rotated while being braked, the sliding door closing operation is braked. Therefore, it is possible to prevent the sliding door or the member at the door closing portion from being damaged or causing noise. (See Patent Document 1 below)
JP 2002-54348 A

しかし、前記特許文献１に記載の技術は、病院、オフィス、図書館、高齢者用住宅、倉庫等に取付けた重量のある引戸（重量引戸）に用いた場合、一旦引戸が閉じ始めると、閉じ力発生手段による閉じ力に加え、扉の重量によるイナーシャ（慣性）により閉じ速度が増大し、全閉扉時に戸枠の竪枠などの部材に強く当接した衝撃により、引戸や閉扉箇所の部材などを損傷したり、騒音を生じることとなり、重量引戸への制動には不十分であるという問題がある。   However, when the technique described in Patent Document 1 is used for a heavy sliding door (heavy sliding door) attached to a hospital, office, library, elderly house, warehouse, etc., once the sliding door starts to close, the closing force In addition to the closing force generated by the generating means, the closing speed increases due to inertia (inertia) due to the weight of the door, and when the door is fully closed, the impact of the door frame, such as the frame of the door frame, causes the door to close. There is a problem that damage or noise is generated, which is insufficient for braking the weight sliding door.

そこで、本発明は、重量引戸であっても、閉扉時に戸枠の竪枠などの部材に強く当接した衝撃により、引戸や閉扉箇所の部材などを損傷したり、騒音を生じることのない制動装置を備えた引戸装置を提供することを目的とする。   Therefore, the present invention provides a braking system that does not damage a sliding door or a member at a closed portion or cause noise due to an impact that strongly contacts a member such as a frame of the door frame when the door is closed even when the door is closed. An object of the present invention is to provide a sliding door device including the device.

The present invention provides a sliding door that is movably provided to open and close the sliding door frame, a closing force generating means for moving the sliding door in the closing direction, and brakes the sliding door before the sliding door is fully closed. in the sliding door device provided with a braking device for, the braking device is provided above the the cited door Rutotomoni a rack whose length is configured longer than the lateral width of the cited door, of the cited door with respectively provided door leading side and the door trailing end side and a braking means having a meshing pinion gears to the rack, pinion gear braking means door end side in the fully open door state of the cited door is and the rack and meshed, perform braking means braking該戸destination side in the case of the cited door is closed from the fully open door state, pin Niongia is the rack door trailing side of the brake means when the cited door is near full closing state 該戸destination side of the braking means and the I and meshing Both braking means trailing is mainly characterized in that the braking.

前記のごとく、本発明の引戸の制動装置は、該引戸の上方に設けられるとともに、その長さが該引戸の左右方向の幅よりも長く構成されたラックと、該引戸の戸先側と戸尻側にそれぞれ設けられるとともに、該ラックに噛合うピニオンギアを備えた制動手段とからなり、該引戸の全開扉状態において戸先側の制動手段のピニオンギアが該ラックと噛合っており、該引戸が全開扉状態から閉じられる場合には該戸先側の制動手段が制動を行い、該引戸が全閉扉状態近くになると戸尻側の制動手段のピニオンギアが該ラックと噛合って該戸先側の制動手段と該戸尻側の制動手段の両方が制動を行うので、引戸の閉じ始めの速度を遅くすることができ、人が通り抜ける余裕が確保できる。また、重量引戸であっても十分な制動を掛けることが可能となり、引戸や閉扉箇所の部材などを損傷したり、騒音を生じることがない。
Wherein as the braking device of the sliding door of the present invention, Rutotomoni provided above the the cited door, a rack whose length is configured longer than the lateral width of the cited door, and door end side of the cited door with respectively provided door trailing end side and a braking means having a meshing pinion gears to the rack, pinion gear braking means door end side is Tsu said rack meshing in the fully open door state of the cited door performs braking means braking該戸destination side in the case of the cited door is closed from the fully open door state, peak Niongia the door trailing side of the brake means when the cited door is near full closing state I the rack meshing since both of the braking means and該戸buttocks side of the braking means of該戸destination side performs the braking, it is possible to slow down the closing beginning of the speed of the sliding door can be secured afford to pass through a person. In addition, even a heavy sliding door can be sufficiently braked, and the sliding door and the member at the closed portion are not damaged and noise is not generated.

本発明の引戸装置では、引戸が重量引戸であっても十分な制動を掛けることが可能となり、引戸や閉扉箇所の部材などを損傷したり、騒音を生じることがなくなるという利点がある。   In the sliding door device of the present invention, even if the sliding door is a heavy sliding door, it is possible to perform sufficient braking, and there is an advantage that the sliding door, the member at the closing position, and the like are not damaged and noise is not generated.

以下、本発明の第一実施の形態を図面に基づき詳細に説明する。図１〜図５において、１は引戸枠２に左右方向に移動自在に吊り下げられた上吊り方式の引戸を示す。なお、本実施の形態では、右開き用の引戸を例示するが、反対に左開き用の引戸であっても良いことは無論である。前記引戸枠２は、前記引戸１の閉じ側竪枠３と開き側竪枠４の上端間を上横枠５で、それぞれ連結して形成されたものである。図中開き側竪枠４の引戸１の戸尻側に位置する側面には、引戸１の全開時、戸尻が竪枠４に衝突した時の衝撃を緩和するための２つの緩衝材４ａが設けられている。   Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 1 to FIG. 5, reference numeral 1 denotes a sliding door that is suspended from a sliding door frame 2 so as to be movable in the left-right direction. In the present embodiment, a sliding door for right opening is illustrated, but it goes without saying that it may be a sliding door for left opening. The sliding door frame 2 is formed by connecting the upper end of the closing side frame 3 and the opening side frame 4 of the sliding door 1 with an upper horizontal frame 5. In the side of the sliding side door 4 of the opening side frame 4 in the figure, two cushioning materials 4a for reducing the impact when the sliding edge 1 collides with the side frame 4 when the sliding door 1 is fully opened. Is provided.

前記引戸１の上縁部にあってほぼ両端部には、戸先側ブラケット６ａと閉尻側ブラケット６ｂが上方に延設され、この２つのブラケット６ａ，６ｂに各々２つの戸車７が回転自在に軸支されている。   A door end side bracket 6a and a closed butt side bracket 6b are extended upward at almost both ends at the upper edge of the sliding door 1, and two door wheels 7 are rotatable on the two brackets 6a and 6b, respectively. Is pivotally supported.

前記上横枠５には、その左右方向の幅のほぼ全域にわたって断面略Ｌ字状のフレーム１５が水平に固定され、このフレーム１５に形成されたレール部１６上に、前記戸車７が転動自在に載置され、レール部１６上を戸車７が転動することにより、引戸１の開閉動作が行われる。   A frame 15 having a substantially L-shaped cross section is fixed horizontally to the upper horizontal frame 5 over almost the entire width in the left-right direction, and the door wheel 7 rolls on a rail portion 16 formed on the frame 15. The sliding door 1 is opened and closed as the door 7 rolls on the rail portion 16 and is freely mounted.

前記レール部１６の戸先側端部には、図１、図４に示すように、本発明の閉じ力発生手段に相当する閉扉駆動装置２１が固定されている。この閉扉駆動装置２１はその本体１８内部にぜんまいバネ（図示せず）を備え、このぜんまいバネにより回転するドラム２０の外周に巻きつけられた駆動ワイヤ１９とを備えている。そして、この駆動ワイヤ１９の先端が前記戸先側ブラケット６ａに連結され、ぜんまいバネのバネ力により引戸１を閉扉方向に常時付勢している。従って、引戸１が人の力で開扉された後、手を放されると、引戸１はぜんまいバネのバネ力により駆動ワイヤ１９に引っ張られ、自動的に閉扉することとなる。なお、図４に示すように、図１では図示を省略しているが、閉扉駆動装置２１等を備えた上横枠５の前面は、点検カバー２２で覆われている。   As shown in FIGS. 1 and 4, a door driving device 21 corresponding to the closing force generating means of the present invention is fixed to the door end side end of the rail portion 16. The door closing drive device 21 includes a mainspring spring (not shown) in the main body 18 and a drive wire 19 wound around the outer periphery of a drum 20 rotated by the mainspring spring. And the front-end | tip of this drive wire 19 is connected with the said door-end side bracket 6a, and the sliding door 1 is always urged | biased by the spring force of a mainspring spring in the closing direction. Accordingly, when the sliding door 1 is opened by human power and then released, the sliding door 1 is pulled by the drive wire 19 by the spring force of the mainspring spring, and is automatically closed. As shown in FIG. 4, although not shown in FIG. 1, the front surface of the upper horizontal frame 5 including the door closing drive device 21 and the like is covered with an inspection cover 22.

前記フレーム１５上には、図１、図５に示すように、引戸１の全閉状態において、この引戸１の上縁部に対向する位置にラック１７が、引戸１の開閉方向に沿ってレール部１６に並行して設けられている。このラック１７は、所定の長さの３本のラック１７ａ，１７ｂ，１７ｃを連結し、一つの連続したものに構成されている。その長さは、引戸１の左右方向の幅の略半分よりも長く構成されている。なお、このラック１７は、継ぎ目のない一本ものであってもよいし、所定の長さのものを複数本連結し、一つの連続したものに構成してもよい。   On the frame 15, as shown in FIGS. 1 and 5, in a fully closed state of the sliding door 1, a rack 17 is provided at a position facing the upper edge of the sliding door 1 along the opening / closing direction of the sliding door 1. It is provided in parallel with the section 16. The rack 17 is configured by connecting three racks 17a, 17b, and 17c having a predetermined length to form a single continuous rack. The length is configured to be longer than substantially half of the width in the left-right direction of the sliding door 1. The rack 17 may be a single piece that is seamless, or a plurality of racks having a predetermined length may be connected to form a single continuous piece.

前記戸先側ブラケット１２ａの戸尻側と戸尻側ブラケット１２ｂの戸先側には、同じ構造をした制動手段８がそれぞれ一個づつ設けられている。この２つの制動手段８は、正逆回転自在に支持された入力軸１０に制動力（回転抵抗）を付与するもので、このような制動機能を発揮し得る限りその構造は任意である。例えば、本実施の形態では、トロコイドポンプを備えた油圧式ダンパを採用している。また、本実施の形態の制動手段８には、制動力を調整するための絞り弁８ａが設けられており、この絞り弁８ａを調整することにより任意の値に制動力を調整可能としている。従って、戸先側と戸尻側の制動手段８の制動力をそれぞれ異なる値に設定することも可能である。   One braking means 8 having the same structure is provided on each of the door end side of the door end side bracket 12a and the door end side of the door end side bracket 12b. These two braking means 8 give a braking force (rotational resistance) to the input shaft 10 supported so as to be freely rotatable forward and backward, and the structure thereof is arbitrary as long as such a braking function can be exhibited. For example, in this embodiment, a hydraulic damper provided with a trochoid pump is employed. Further, the braking means 8 of the present embodiment is provided with a throttle valve 8a for adjusting the braking force, and the braking force can be adjusted to an arbitrary value by adjusting the throttle valve 8a. Therefore, it is also possible to set the braking force of the braking means 8 on the door end side and the door bottom side to different values.

前記各制動手段８に支持された各入力軸１０には、それぞれピニオンギヤ９が取り付けられている。この２つのピニオンギヤ９は、ともにフレーム１５に設けられた同一のラック１７に噛み合っている。入力軸１０とピニオンギヤ９との間には、それぞれ一方向クラッチ（図示省略）が装着されている。一方向クラッチは、引戸１の閉扉方向にピニオンギヤ９が正回転する際には、ピニオンギヤ９は入力軸１０を回転させてトルク伝達を行い、反対に開扉方向にピニオンギヤ９が逆回転する際には、ピニオンギヤ９を空転させて入力軸１０のトルク伝達を遮断する向きに取り付けられている。すなわち、本実施の形態の制動装置１１は、各々ピニオンギヤ９を備えた２つの制動手段８と、引戸１が略中間域まで閉じられると前記２つのピニオンギヤ９が両方とも噛み合うラック１７とにより構成されている。   A pinion gear 9 is attached to each input shaft 10 supported by each braking means 8. Both of these two pinion gears 9 mesh with the same rack 17 provided on the frame 15. A one-way clutch (not shown) is mounted between the input shaft 10 and the pinion gear 9. In the one-way clutch, when the pinion gear 9 rotates forward in the closing direction of the sliding door 1, the pinion gear 9 rotates the input shaft 10 to transmit torque, and conversely, when the pinion gear 9 rotates in the reverse direction in the door opening direction. Is attached in such a direction that the pinion gear 9 is idled and the torque transmission of the input shaft 10 is cut off. That is, the braking device 11 of the present embodiment includes two braking means 8 each having a pinion gear 9 and a rack 17 in which both the two pinion gears 9 are engaged when the sliding door 1 is closed to a substantially intermediate region. ing.

そして、図２、図３に示すように、本実施の形態のラック１７の長さは、引戸１が開口の略中間域まで閉じられると２つの制動手段８の各ピニオンギア９と噛合い、逆に引戸１が全開扉状態になると、２つの制動手段８の内の戸先側の制動手段８だけと噛み合う長さに設定されている。   As shown in FIGS. 2 and 3, the length of the rack 17 according to the present embodiment is such that when the sliding door 1 is closed to a substantially middle region of the opening, it meshes with the pinion gears 9 of the two braking means 8. On the contrary, when the sliding door 1 is in the fully opened state, the length is set so as to mesh with only the braking means 8 on the door end side of the two braking means 8.

本発明の第一実施の形態の引戸装置は、前記のように構成されているので、引戸１が、閉扉駆動装置２１により図３に示す全開扉状態から閉扉方向に閉じられようとする場合、戸先側の制動手段８のピニオンギア９は、全閉扉状態、全開扉状態のいずれにおいてもラック１７と噛み合っているので、引戸１には戸先側の制動手段８による制動がかかる。このため病院や高齢者用住宅において、引戸１の閉じ始めの速度を遅くすることができ、人が通り抜ける余裕が確保できる。さらに引戸１が閉じられほぼ中間域までくると、図２に示すように戸尻側の制動手段８のピニオンギア９が前記と同一のラック１７の戸尻側端部と噛み合いはじめる。この状態からは戸先側と戸尻側の両方の制動手段８による制動がかかり始める。以降、図１に示す全閉扉状態となるまで２つの制動手段８による制動がかかることとなる。このため、重量のある引戸１は、閉扉駆動装置２１による閉じ速度に加え、引戸１自体の重量によるイナーシャ（慣性）により、閉じ速度が増大しても十分に制動がかかり、引戸１や引戸枠２の部材などを損傷したり、騒音を生じることがなくなる。   Since the sliding door device of the first embodiment of the present invention is configured as described above, when the sliding door 1 is about to be closed in the closing direction from the fully open state shown in FIG. Since the pinion gear 9 of the braking means 8 on the door end side meshes with the rack 17 in both the fully closed state and the fully open state, the sliding door 1 is braked by the braking means 8 on the door end side. For this reason, in a hospital or a house for the elderly, the speed at which the sliding door 1 starts to be closed can be slowed, and a room for people to pass through can be secured. Further, when the sliding door 1 is closed and comes to a substantially middle region, the pinion gear 9 of the door-side braking means 8 starts to mesh with the door-side end of the same rack 17 as shown in FIG. From this state, braking by the braking means 8 on both the door end side and the door bottom side starts to be applied. Thereafter, braking by the two braking means 8 is applied until the fully closed state shown in FIG. 1 is reached. For this reason, the heavy sliding door 1 is sufficiently braked even if the closing speed increases due to the inertia (inertia) due to the weight of the sliding door 1 itself in addition to the closing speed by the closing door driving device 21. The member 2 is not damaged or no noise is generated.

次に、本発明の第二実施の形態を図６に基づき説明する。なお、同一部材には同一符号を付してその説明は省略する。   Next, a second embodiment of the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the same member and the description is abbreviate | omitted.

図６に示すように、所定の長さの３本のラック１７０ａ，１７０ｂ，１７０ｃを連結し、一つの連続したものに構成されたラック１７０の長さは、引戸１が全閉扉状態近くになると２つの制動手段８の各ピニオンギア９と噛合い、逆に引戸１が全開扉状態となると、２つの制動手段８のピニオンギア９の両方とも噛合わなくなる長さに設定されている。   As shown in FIG. 6, three racks 170a, 170b and 170c having a predetermined length are connected to each other, and the length of the rack 170 configured as one continuous is such that the sliding door 1 is close to a fully closed state. When the sliding door 1 is fully opened, the length is set so that both of the pinion gears 9 of the two braking means 8 are not engaged with each other.

本発明の第二実施の形態の引戸装置は、前記のように構成されているので、引戸１が、閉扉駆動装置２１により図６に示す全開扉状態から閉扉方向に閉じられようとする場合、２つの制動手段８のいずれの制動手段８のピニオンギア９とも噛み合っていないので、戸尻側の制動手段８のピニオンギア９がラック１７０と噛み合うまでは、制動がかかることがなく、閉扉駆動装置２１により素早く閉じられる。従って、オフィス、倉庫等のように早く引戸１を閉じたい場合に有効である。   Since the sliding door device of the second embodiment of the present invention is configured as described above, when the sliding door 1 is to be closed in the closing direction from the fully open state shown in FIG. Since neither of the two braking means 8 meshes with the pinion gear 9 of the braking means 8, no braking is applied until the pinion gear 9 of the braking means 8 on the door bottom side meshes with the rack 170, and the door closing drive device 21 closes quickly. Therefore, it is effective when it is desired to close the sliding door 1 quickly such as in an office or a warehouse.

また、本発明で、複数の制動手段８の各ピニオンギア９が同一のラック１７，１７０と噛合うところの、引戸１の”全閉扉状態近く”とは、引戸１が図２に示す略中間域から閉じ側竪枠３の手前３０センチ程度までの間に閉じられた状態をいう。
例えば、第二実施の形態において、引戸１が閉じ側竪枠３の手前３０センチ程度に閉じられた状態で、複数の制動手段８の各ピニオンギア９が同一のラック１７０と噛合う状態とするためには、戸尻側の制動手段８を戸先側の制動手段８により近づけるとともに、ラック１７０をより短くすることとなる。 Further, in the present invention, the “near fully closed state” of the sliding door 1 where the pinion gears 9 of the plurality of braking means 8 mesh with the same racks 17 and 170 means that the sliding door 1 is substantially in the middle as shown in FIG. It is in a state of being closed from the area to about 30 cm before the closed side frame 3.
For example, in the second embodiment, the pinion gears 9 of the plurality of braking means 8 are engaged with the same rack 170 in a state in which the sliding door 1 is closed about 30 cm before the closed side frame 3. For this purpose, the door bottom brake means 8 is brought closer to the door tip brake means 8 and the rack 170 is made shorter.

なお、引戸１の全閉状態近くにおいて大きな制動力を働かせる制動装置の構成として、上横枠５にラックを図中上下方向、または出入り方向（図面に垂直な方向）へ２列に設け、それぞれのラックに制動手段８のピニオンギヤ９を噛み合せることも可能であるが、この構成では上横枠５の上下方向の幅が大きくなったり、制動装置自体が上下方向、または出入り方向に大きくなるという問題がある。
しかし、本発明では、引戸１の全閉扉状態近くにおいて同一のラック１７，１７０に２つの制動装置８のそれぞれのピニオンギヤ９を噛み合せ、大きな制動力を働かせる構成としたので、上横枠５の上下方向の幅を大きくする必要がなく、また制動装置１１が上下方向、または出入り方向のコンパクトになるという利点がある。よって、引戸装置全体が上下方向、または出入り方向においてコンパクトになる。 In addition, as a structure of the braking device that exerts a large braking force near the fully closed state of the sliding door 1, the upper horizontal frame 5 is provided with racks in two rows in the vertical direction in the figure or in the entrance / exit direction (direction perpendicular to the drawing). It is also possible to engage the pinion gear 9 of the braking means 8 with this rack, but with this configuration, the vertical width of the upper horizontal frame 5 is increased, or the braking device itself is increased in the vertical direction or in / out direction. There's a problem.
However, in the present invention, since the pinion gears 9 of the two braking devices 8 are meshed with the same racks 17 and 170 near the fully closed state of the sliding door 1 and a large braking force is applied, the upper and lower sides of the upper horizontal frame 5 are There is no need to increase the width in the direction, and there is an advantage that the braking device 11 is compact in the vertical direction or in / out direction. Therefore, the whole sliding door device becomes compact in the up-down direction or in / out direction.

また、本発明は前記実施の形態に限定されるものではなく、引戸の使用目的に応じて、引戸が全開扉状態近くになると制動装置が作動する開扉用制動装置を併設しても良いし、閉じ初めの所定の距離だけ低速で閉じさせるディレードアクション機能を具備することも可能である。   In addition, the present invention is not limited to the above-described embodiment, and depending on the purpose of use of the sliding door, a door-opening braking device that activates the braking device when the sliding door becomes nearly fully open may be provided. It is also possible to provide a delayed action function that closes at a low speed for a predetermined distance at the beginning of closing.

さらに、閉じ力発生手段は、前記のものに限定されることはなく、ウェイトの重量により引戸を閉扉方向に引っ張るものや、引戸に設けた車輪を、閉扉方向側を少し下方に傾斜させたレール上に転動自在に載置して、引戸の自重により自動的に閉扉させたもの等が採用可能である。   Further, the closing force generating means is not limited to the above-described one, and a rail that pulls the sliding door in the closing direction due to the weight of the weight, or a rail in which the door provided on the sliding door is inclined slightly downward in the closing direction side. It is possible to adopt one that is mounted so as to be able to roll on and is automatically closed by its own weight.
