Description

本発明は、自動ドア駆動装置に関し、特に、停電時等、手動で引戸を開閉する必要が生じたときに小さい力で引戸を開閉することのできる自動ドア駆動装置に関するものである。   The present invention relates to an automatic door drive device, and more particularly to an automatic door drive device that can open and close a sliding door with a small force when it is necessary to manually open and close the sliding door during a power failure or the like.

現在、日本では核家族化や高齢化が進み、老人の一人暮しや、身障者の一人暮しも増えてきている。
身障者はドアを押して開けるのは容易でも振り向いて閉めるのは大変であることから、ドアを引戸にリフォームし、この引戸に自動ドア駆動装置を取り付けて自動ドアにする施工も増えつつある。 At present, nuclear families and aging in Japan are increasing, and the number of elderly people living alone and those living with disabilities are also increasing.
Although it is difficult for people with disabilities to push and open the door, it is difficult to turn and close the door. Therefore, the door is reformed into a sliding door, and an automatic door driving device is attached to the sliding door to make an automatic door.

従来の自動ドア駆動装置としては、例えば、下記の特許文献１に記載されるものが知られている。
この自動ドア駆動装置は、所定の間隔で配設したプーリに伝動ベルトを架設するとともに、該伝動ベルトに固定した結合金具を引戸に固定し、プーリをモータで回転させることにより、引戸の駆動力を得るようにしている。 As a conventional automatic door drive device, for example, one described in Patent Document 1 below is known.
This automatic door driving device is constructed by installing a transmission belt on pulleys arranged at predetermined intervals, fixing a coupling fitting fixed to the transmission belt to the sliding door, and rotating the pulley with a motor, thereby driving the sliding door. Like to get.

ところで、このような自動ドア駆動装置においては、駆動側のプーリがモータに直結されているため、停電時等、引戸を手動で開閉しようとしたとき、停止しているモータを回すことのできる力で引戸を移動させなければならず、老人や身障者では引戸の開閉が困難であるという問題があった。
特開２００１−３５５３７６号公報 特開２００６−２３５２号公報 By the way, in such an automatic door drive device, since the pulley on the drive side is directly connected to the motor, when the sliding door is manually opened and closed at the time of a power failure or the like, the force that can turn the stopped motor is turned. There is a problem that the sliding doors must be moved, and it is difficult for the elderly and disabled people to open and close the sliding doors.
JP 2001-355376 A JP 2006-2352 A

本発明は、上記従来の自動ドア駆動装置が有する問題点に鑑み、老人や身障者のように力の弱い人であっても、手動での引戸の開閉が容易に行うことのできる自動ドア駆動装置を提供することを目的とする。   In view of the problems of the conventional automatic door drive device, the present invention is an automatic door drive device that can easily open and close the sliding door manually even for a weak person such as an elderly person or a disabled person. The purpose is to provide.

上記目的を達成するため、本発明の自動ドア駆動装置は、引戸を開閉する駆動機構を備え、駆動プーリと従動プーリにワイヤを架設するとともに、該ワイヤに固定した結合金具を引戸に固定し、駆動プーリをモータで回転させることによって引戸の駆動力を得るようにした自動ドア駆動装置において、モータのモータ軸と駆動プーリの回転軸とを、鴨居に取り付けた選択伝達機構のフレームに引戸の駆動方向と平行となるように軸支し、該フレーム内に、モータ軸に配設した平歯車からなる駆動歯車と、駆動プーリの回転軸に配設した平歯車からなるプーリ歯車と、前記モータ軸に揺動自在に配設した揺動板に駆動歯車に対して対称となるよう駆動歯車に噛合して配設した２個の平歯車からなる切替歯車とを配設し、モータからの回転力は切替歯車がモータの回転に伴って揺動板が揺動して選択的にプーリ歯車に噛合して駆動プーリに伝達し、駆動プーリからの回転力は切替歯車がプーリ歯車から離間することによって駆動歯車及びモータには伝達しないようにし、駆動プーリから導出したワイヤをそれぞれ補助プーリを使用して方向を９０度曲げて水平に配設した従動プーリに架け渡すようにしたことを特徴とする。 In order to achieve the above object, the automatic door driving device of the present invention includes a driving mechanism that opens and closes a sliding door, constructs a wire between a driving pulley and a driven pulley, and fixes a coupling fitting fixed to the wire to the sliding door, In an automatic door driving device that obtains the driving force of the sliding door by rotating the driving pulley with a motor, the sliding shaft is driven by the frame of the selective transmission mechanism that is attached to the Kamoi with the motor shaft of the motor and the rotating shaft of the driving pulley. axially supported to be parallel to the direction, in the frame, a drive gear formed of spur gear is disposed on the motor shaft, a pulley gear consisting of spur gears disposed on the rotary shaft of the drive pulley, said motor shaft And a switching gear made up of two spur gears arranged in mesh with the drive gear so as to be symmetric with respect to the drive gear. Cut off As the gear rotates, the swing plate swings and selectively engages with the pulley gear and is transmitted to the drive pulley. The rotational force from the drive pulley is driven by the switching gear separating from the pulley gear. Further, it is characterized in that it is not transmitted to the motor, and the wires led out from the driving pulley are respectively bridged on a driven pulley arranged horizontally by bending the direction by 90 degrees using auxiliary pulleys .

本発明の自動ドア駆動装置によれば、モータのモータ軸と駆動プーリの回転軸とを選択伝達機構によって連結し、モータの回転力は駆動プーリに伝達し、駆動プーリの回転力はモータに伝達しないようにしたから、手動で引戸を開閉する必要が生じたときでも、停止している駆動機構のモータを回転させるための力を必要とせず、老人や身障者のように力の弱い人であっても、手動での引戸の開閉が容易に行うことのできる自動ドア駆動装置を提供することができる。   According to the automatic door driving device of the present invention, the motor shaft of the motor and the rotating shaft of the driving pulley are connected by the selective transmission mechanism, the rotating force of the motor is transmitted to the driving pulley, and the rotating force of the driving pulley is transmitted to the motor. Even if it is necessary to manually open and close the sliding door, it does not require the force to rotate the motor of the stopped drive mechanism, and it is a weak person such as the elderly or the disabled. However, it is possible to provide an automatic door driving device that can easily open and close the sliding door manually.

また、選択伝達機構を、モータ軸に配設した駆動歯車と、駆動プーリの回転軸に配設したプーリ歯車と、前記モータ軸に揺動自在に配設した揺動板に駆動歯車に対して対称となるよう駆動歯車に噛合して配設した２個の切替歯車とから構成し、モータの回転力は切替歯車がプーリ歯車に噛合して駆動プーリに伝達し、駆動プーリからの回転力は切替歯車がプーリ歯車から離間することによって駆動歯車には伝達しないようにするときは、モータの回転に伴って揺動板が揺動して何れかの切替歯車がプーリ歯車と噛合し、モータの回転力を駆動プーリに確実に伝達するも、プーリ歯車に噛合している切替歯車は、モータ軸に揺動板を介して取り付けられており、モータ軸が停止しているときは不安定な状態であり、手動で引戸を動かしたときにワイヤを介して伝達される駆動プーリの回転によって、プーリ歯車と切替歯車間に滑りが生じ、切替歯車がプーリ歯車から離れることにより駆動プーリからの回転力はモータに伝達されることがないようになっている。   The selection transmission mechanism is connected to the drive gear on the drive gear disposed on the motor shaft, the pulley gear disposed on the rotation shaft of the drive pulley, and the swing plate disposed swingably on the motor shaft. It consists of two switching gears meshed with the drive gear so as to be symmetrical, and the rotational force of the motor is transmitted to the drive pulley by the switching gear meshing with the pulley gear, and the rotational force from the drive pulley is When the switching gear is separated from the pulley gear so as not to be transmitted to the driving gear, the swinging plate swings with the rotation of the motor, and any of the switching gears meshes with the pulley gear. Although the rotational force is reliably transmitted to the drive pulley, the switching gear meshing with the pulley gear is attached to the motor shaft via a swing plate and is unstable when the motor shaft is stopped. And when you manually move the sliding door The rotation of the driving pulley transmitted through the ear causes slippage between the pulley gear and the switching gear, and the switching gear is separated from the pulley gear so that the rotational force from the driving pulley is not transmitted to the motor. It has become.

以下、本発明の自動ドア駆動装置の実施の形態を、図面に基づいて説明する。   Embodiments of the automatic door driving device of the present invention will be described below with reference to the drawings.

図１〜図６に、本発明の自動ドア駆動装置の一実施例を示す。   1 to 6 show an embodiment of an automatic door driving device of the present invention.

この自動ドア駆動装置１は、図１〜図２に示すように、鴨居Ｋに取り付け、引戸Ｄを自動ドアとして使用するものであり、引戸Ｄを開閉する駆動機構２を備え、引戸Ｄを自動で開閉するようにしている。   As shown in FIGS. 1 to 2, the automatic door driving device 1 is attached to the Kamoi K and uses the sliding door D as an automatic door. The automatic door driving device 1 includes a driving mechanism 2 that opens and closes the sliding door D. It opens and closes with.

駆動機構２は、図１〜図２に示すように、所定の間隔で配設した駆動プーリ６と従動プーリ７にワイヤ８を架設するとともに、該ワイヤ８に固定した結合金具９を引戸Ｄに固定し、駆動プーリ６を選択伝達機構３を介してモータ４で回転させることにより、引戸Ｄの駆動力を得るようにしている。   As shown in FIGS. 1 to 2, the drive mechanism 2 lays a wire 8 between a drive pulley 6 and a driven pulley 7 disposed at a predetermined interval, and a coupling fitting 9 fixed to the wire 8 is attached to the sliding door D. A driving force of the sliding door D is obtained by fixing and rotating the driving pulley 6 by the motor 4 via the selective transmission mechanism 3.

駆動プーリ６は、従動プーリ７と同一平面上に配設（参考例）しても構わないが、本実施例においては、補助プーリＰ１、Ｐ２を使用してワイヤ８の進行を略９０度曲げ、従動プーリ７の配設面に対して垂直な面に配設するようにしている。
これによって、モータ４と駆動プーリ６間に配備した選択伝達機構３によって生じる長手寸法の延長分を引戸Ｄの進行方向と平行方向に逃がすことができる。 The drive pulley 6 may be arranged on the same plane as the driven pulley 7 (reference example), but in this embodiment, the auxiliary pulleys P1 and P2 are used to bend the progress of the wire 8 by approximately 90 degrees. In this case, the driven pulley 7 is disposed on a surface perpendicular to the disposed surface.
Thereby, the extension of the longitudinal dimension generated by the selective transmission mechanism 3 disposed between the motor 4 and the drive pulley 6 can be released in a direction parallel to the moving direction of the sliding door D.

駆動プーリ６は、回転軸６ａに対して軸方向に対して平行に摺動可能に配設することが好ましく、これによって、駆動プーリ６に複数回巻かれるワイヤ８を絡ませることなく巻き取ることができる。   The drive pulley 6 is preferably disposed so as to be slidable in parallel to the axial direction with respect to the rotating shaft 6a, whereby the wire 8 wound around the drive pulley 6 is wound without being entangled. Can do.

そして、この自動ドア駆動装置１は、図３に示すように、駆動機構２の駆動源であるモータ４のモータ軸４ａと駆動プーリ６の回転軸６ａとを選択伝達機構３によって連結し、モータ４からの回転力は駆動プーリ６に伝達し、駆動プーリ６からの回転力はモータ４に伝達しないようにしている。   As shown in FIG. 3, the automatic door driving apparatus 1 connects a motor shaft 4a of a motor 4 which is a driving source of the driving mechanism 2 and a rotating shaft 6a of a driving pulley 6 by a selective transmission mechanism 3, and the motor The rotational force from 4 is transmitted to the drive pulley 6, and the rotational force from the drive pulley 6 is not transmitted to the motor 4.

選択伝達機構３は、図３〜図４に示すように、モータ４のモータ軸４ａに配設した駆動歯車３０と、駆動プーリ６の回転軸６ａに配設したプーリ歯車３１と、前記モータ軸４ａに揺動自在に配設した揺動板３３、３３に駆動歯車３０に対して対称となるよう駆動歯車３０に噛合して配設した２個の切替歯車３２ａ、３２ｂとから構成し、モータ４の回転力は、切替歯車３２ａ、３２ｂの何れかがプーリ歯車３１に噛合して駆動プーリ６に伝達し、駆動プーリ６からの回転力は切替歯車３２ａ、３２ｂがプーリ歯車３１から離間することによって駆動歯車３０には伝達しないようにしている。   As shown in FIGS. 3 to 4, the selective transmission mechanism 3 includes a driving gear 30 disposed on the motor shaft 4 a of the motor 4, a pulley gear 31 disposed on the rotating shaft 6 a of the driving pulley 6, and the motor shaft. 4a. The two switching gears 32a and 32b, which are arranged in mesh with the drive gear 30 so as to be symmetric with respect to the drive gear 30, are arranged on the swing plates 33 and 33 that are swingably arranged on the motor 4a. 4 is transmitted to the drive pulley 6 by either of the switching gears 32 a and 32 b meshing with the pulley gear 31, and the switching gears 32 a and 32 b are separated from the pulley gear 31. Thus, transmission to the drive gear 30 is prevented.

具体的には、モータ４のモータ軸４ａに駆動歯車３０を挟む位置に揺動自在に取り付けた揺動板３３、３３に駆動歯車３０と噛合するように配設した切替歯車３２ａ、３２ｂがプーリ歯車３１と噛合していない状態（図３（ａ）参照）から、モータ軸４ａが、図３（ｂ）に示すように、時計回りに回転をすることによって、揺動板３３、３３が回転するモータ軸４ａに伴って揺動し、切替歯車３２ａがプーリ歯車３１と噛合する。
切替歯車３２ａと噛合したプーリ歯車３１は、モータ軸４ａと同じ時計周りに回転することとなり、駆動プーリ６にモータ４の回転力が伝達され、引戸Ｄの開放又は閉鎖が行われる。
そして、図３（ｃ）に示すように、モータ４を半時計回りに回転をさせることによって、揺動板３３が回転するモータ軸４ａに伴って揺動し、切替歯車３２ｂがプーリ歯車３１と噛合して、プーリ歯車３１が、モータ軸４ａと同じ半時計周りに回転することとなり、駆動プーリ６にモータ４の回転力が伝達され、引戸Ｄの閉鎖又は開放が行われる。 Specifically, the switching gears 32a and 32b disposed so as to mesh with the driving gear 30 are swing pulleys 33 and 33 that are swingably attached to the motor shaft 4a of the motor 4 at positions where the driving gear 30 is sandwiched. When the motor shaft 4a rotates clockwise as shown in FIG. 3 (b) from the state where it is not meshed with the gear 31 (see FIG. 3 (a)), the swing plates 33 and 33 are rotated. As the motor shaft 4 a swings, the switching gear 32 a meshes with the pulley gear 31.
The pulley gear 31 meshed with the switching gear 32a rotates in the same clockwise direction as the motor shaft 4a, and the rotational force of the motor 4 is transmitted to the drive pulley 6 so that the sliding door D is opened or closed.
Then, as shown in FIG. 3C, by rotating the motor 4 counterclockwise, the swing plate 33 swings along with the rotating motor shaft 4a, and the switching gear 32b is connected to the pulley gear 31. As a result, the pulley gear 31 rotates in the same counterclockwise direction as the motor shaft 4a, and the rotational force of the motor 4 is transmitted to the drive pulley 6 so that the sliding door D is closed or opened.

次に、歯車の位置関係が、図４（ａ）に示す位置にあり、引戸Ｄが閉鎖状態であるときに停電等によって、モータ４が駆動しなくなったときの引戸Ｄの手動での開閉方法を説明する。   Next, when the positional relationship of the gears is at the position shown in FIG. 4A and the sliding door D is in the closed state, the sliding door D is manually opened and closed when the motor 4 is not driven due to a power failure or the like. Will be explained.

まず、引戸Ｄを手動で開放する方向に力を加える。このとき、引戸Ｄへの開放力は、結合金具９を介してワイヤ８に伝達され、プーリ歯車３１を図例においては、反時計回りに回転させることとなる。
この場合、モータ軸４ａに揺動自在に配設されている揺動板３３は負荷のかかっていないフリー状態で、プーリ歯車３１と噛合していた切替歯車３２ａは、プーリ歯車３１の回転によって、図４（ｂ）に示すように、両歯車間で滑りが生じ、プーリ歯車３１から離間することとなる。
これによって、プーリ歯車３１に回転力となって伝わる引戸Ｄへの手動による開放力は、駆動歯車３０には伝達されることなく、引戸Ｄの開放力としてモータ４を手動で回すだけの力を必要とすることはない。 First, a force is applied in the direction of manually opening the sliding door D. At this time, the opening force to the sliding door D is transmitted to the wire 8 through the coupling fitting 9, and the pulley gear 31 is rotated counterclockwise in the illustrated example.
In this case, the swinging plate 33 slidably disposed on the motor shaft 4 a is in a free state where no load is applied, and the switching gear 32 a meshed with the pulley gear 31 is rotated by the rotation of the pulley gear 31. As shown in FIG. 4B, slip occurs between the two gears, and the gears are separated from the pulley gear 31.
Thus, the manual opening force to the sliding door D transmitted as a rotational force to the pulley gear 31 is not transmitted to the drive gear 30, but a force sufficient to manually rotate the motor 4 as the sliding door D opening force. I don't need it.

この場合、図５に示すように、揺動板３３の切替歯車３２ａ、３２ｂの下側に、常時は切替歯車３２ａ、３２ｂを駆動歯車３０から離間させる方向に付勢する付勢手段５を配設することができる。
これによって、引戸Ｄを手動で動かすとき、プーリ歯車３１には一切の負荷が生じることがなく、手動での開放時に若干生じることのある抵抗も一切発生させることがない。
付勢手段５は、その構成を特に限定されるものではなく、モータ４が停止したときに切替歯車３２ａ、３２ｂを駆動歯車３０から離間させることができる程度の小さな付勢力を発生するものであればよく、例えば、巻バネやスプリング等の弾性部材５０を図５に示すように、一端を揺動板３３の取り付けるとともに、他端を駆動機構２を取り付けるケーシング内適所に取り付けるようにしている。 In this case, as shown in FIG. 5, the biasing means 5 that normally biases the switching gears 32 a and 32 b away from the drive gear 30 is arranged below the switching gears 32 a and 32 b of the swing plate 33. Can be set.
As a result, when the sliding door D is moved manually, no load is generated on the pulley gear 31 and no resistance that may occur slightly when manually opened is generated.
The biasing means 5 is not particularly limited in its configuration, and may generate a biasing force that is small enough to separate the switching gears 32a and 32b from the drive gear 30 when the motor 4 is stopped. For example, as shown in FIG. 5, the elastic member 50 such as a winding spring or a spring is attached at one end to the swing plate 33 and attached at the other end to an appropriate position in the casing to which the drive mechanism 2 is attached.

以上、本発明の自動ドア駆動装置について、その実施例に基づいて説明したが、本発明は上記実施例に記載した構成に限定されるものではなく、その趣旨を逸脱しない範囲において適宜その構成を変更することができる。   As mentioned above, although the automatic door drive device of the present invention was explained based on the example, the present invention is not limited to the composition indicated in the above-mentioned example, and the composition is suitably changed in the range which does not deviate from the meaning. Can be changed.

本発明の自動ドア駆動装置は、手動での引戸の開閉が容易に行うことができるという特性を有していることから、例えば、老人や身障者のように力の弱い人が利用する一般住宅や公共施設の引戸の自動ドア駆動装置の用途に好適に用いることができるほか、広く一般の人が利用する引戸の自動ドア駆動装置としても用いることができる。   Since the automatic door driving device of the present invention has a characteristic that it can be easily opened and closed manually, for example, a general house used by a weak person such as an elderly person or a disabled person, In addition to being suitable for use as an automatic door driving device for sliding doors in public facilities, it can also be used as an automatic door driving device for sliding doors widely used by ordinary people.
