Description

本発明は重力式自動扉に関し、具体的には重力により上部傾斜レール上に駆動装置を滑動させその力により扉を自動開閉する重力式自動扉に関する。  The present invention relates to a gravity type automatic door, and more particularly to a gravity type automatic door that slides a driving device on an upper inclined rail by gravity and automatically opens and closes the door by the force.

従来から、電動モーター等の付加動力源を用いることなく、踏み込んだ人間の体荷重による荷重変位を動力源として、出入り口の引き戸を開閉させる機構については、多数の特許文献が存在している。Conventionally, there are many patent documents regarding a mechanism for opening and closing a sliding door at an entrance using a load displacement caused by a human body stepped on as a power source without using an additional power source such as an electric motor.

特許文献1には、踏み込みによる変位量を用いて、リンク機構により引戸の上部又は下部に配置したガイドレールを必要な移動方向へ適宜傾斜させて、この傾斜に沿って引き戸を摺動移動させる方式のものが示されている。  Patent Document 1 discloses a method in which a guide rail disposed at an upper portion or a lower portion of a sliding door is appropriately tilted in a necessary moving direction by a link mechanism using a displacement amount due to depression, and the sliding door is slid along the tilt. Things are shown.

特許第5799358号公報Japanese Patent No. 5799358

特許文献1に示された傾斜方式では、移動が引き戸の自重に起因した斜面上の自然移動のみに頼っているため、応答性の良い素早い移動が難しく、頻繁な出入りには煩わしさがあった。  In the tilt method shown in Patent Document 1, since the movement relies only on the natural movement on the slope due to the weight of the sliding door, it is difficult to move quickly with good responsiveness, and the frequent entry and exit is troublesome. .

また、機構が複雑、使用部品数の多さによる故障時は全体を分解し詳細にわたって原因究明に時間を要し又長年の使用によりガイドレールにゴミなどが蓄積した場合は、その影響を大きく受ける欠点もあった。
さらに加えて、上記構成の作動伝達機構に何らかの障害が発生した場合には、手動によって開閉させることが不可能、又は非常に困難であると言う欠点もある。
Also, if the mechanism is complicated and there is a failure due to the large number of parts used, it will take a long time to disassemble the whole and investigate the cause in detail, and if dust accumulates on the guide rail after many years of use, it will be greatly affected There were also drawbacks.
In addition, if any failure occurs in the operation transmission mechanism configured as described above, there is a disadvantage that it is impossible or very difficult to manually open and close.

そこで、本願発明はかかる課題、すなわち踏み込み作動に対する敏速な応答性の不備、及び設置環境や、踏み込み加重の変化に起因した作動信頼性の不足を解消し、さらには万一の伝達機構の故障時においても、これに影響されず通常の手動扉と同様に無理なく手動開閉する事が出来る重力式自動扉を提供するものである。
また、安価でかつ設置工事費が安く、保守点検が容易で実現性の高い重力式自動開扉を提供することを目的とする。
Therefore, the present invention solves such a problem, that is, lack of quick responsiveness to the stepping operation, and lack of operation reliability due to the installation environment and the change of the stepping weight, and in the event of a failure of the transmission mechanism However, the present invention provides a gravity type automatic door that can be manually opened and closed without being affected by this, as well as a normal manual door.
It is another object of the present invention to provide a gravitational automatic door that is inexpensive, has low installation work cost, is easy to perform maintenance inspection, and is highly feasible.

本発明の重力式自動扉は引戸タイプとし、扉と前記扉上部に設けた吊車と、前記吊車が滑動する下部レールと、前記扉の開閉移動範囲の中央に設けたヒンジを支点として端部が上下動可能な上部傾斜レールと、前記上部傾斜レールを上下動させる駆動機構と、前記上部傾斜レール上を滑動して扉を開閉させる駆動装置と、人を検知する人感センサーとを備え、人を検知した時に扉が開く方向に前記傾斜レールの端部を下げることを特徴とする。  The gravity type automatic door of the present invention is a sliding door type, and has an end portion with a door, a suspension car provided at the upper part of the door, a lower rail on which the suspension car slides, and a hinge provided at the center of the opening / closing movement range of the door as a fulcrum. An upper inclined rail that can move up and down, a drive mechanism that moves the upper inclined rail up and down, a drive device that slides on the upper inclined rail to open and close the door, and a human sensor that detects a person, When detecting this, the end of the inclined rail is lowered in the direction in which the door opens.

本願発明は駆動装置が扉上部に設置しており床面には何もなく出入りがスムーズな動線で、人間以外でも荷物等の出し入れも簡単となる効果がある。The present invention has an effect that the drive device is installed at the upper part of the door, and there is no flow on the floor surface and the flow line is smooth, so that it is easy for people other than humans to take in and out the luggage.

床面の踏み板等が無く、利用者の体重制限が無く、人感センサーにより正確な感知と確 実な動きができる効果がある。  There is no floor tread on the floor, the user's weight is not limited, and there is an effect that the human sensor can accurately detect and move reliably.

床面踏み込み機構が無い為、風雨に対する防御、定期的な雨水の排出、機構内部の防錆 対策も必要がない効果がある。  Since there is no floor depressing mechanism, there is an effect that it is not necessary to protect against wind and rain, regularly discharge rainwater, and prevent rust prevention inside the mechanism.

更に停電時・災害時にも自動扉として使用でき、又万が一故障時は連結シャフトの切り替えにより手動扉として使用が可能である。  Furthermore, it can be used as an automatic door in the event of a power failure or disaster, and in the unlikely event of a failure, it can be used as a manual door by switching the connecting shaft.

また、簡易な構造で構成部品が少なくできているため、より故障が少なく、信頼性のあるものとして利用できる効果がある。  In addition, since the number of components is reduced with a simple structure, there is an effect that it can be used as a reliable one with fewer failures.

本発明の扉の開閉装置は自然重力式となっているため動力エネルギーが省略され省エネ効果は大である。  Since the door opening and closing device of the present invention is a natural gravity type, the power energy is omitted and the energy saving effect is great.

以下、本発明の実施形態を図1〜図8に基づいて説明する。  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

図1は扉10の全閉状態を示しaは正面図、bは平面図である、前記扉10上部に設けた吊車9を下部レール4に載せ扉10の開閉移動範囲中央に設けたヒンジ3を支点として端部を上下動可能な上部傾斜レール5と前記傾斜レール5の端部を上下動させる駆動機構1,2と前記傾斜レール5上を1列2輪の車輪からなる駆動装置6が滑動して前記駆動装置6と連結シャフト7を介して扉を開閉させる。
前記駆動機構1には人を検知する人感センサー8と、を備え、人を検知した時に引戸10が開く方向、すなわち正面から見てヒンジ3を中心に傾斜レール5は右側が上がり、左側が下がり前記傾斜レール上を前記駆動装置が滑動し開く動作となる。
FIG. 1 shows a fully closed state of the door 10, a is a front view, and b is a plan view. A hinge 3 provided on the lower rail 4 is placed on the lower rail 4 and provided at the center of the opening / closing movement range of the door 10. An upper inclined rail 5 whose end is movable up and down with a fulcrum as a fulcrum, driving mechanisms 1 and 2 for moving the end of the inclined rail 5 up and down, and a driving device 6 comprising two rows of wheels on the inclined rail 5. The door is opened and closed via the drive device 6 and the connecting shaft 7 by sliding.
The drive mechanism 1 is provided with a human sensor 8 for detecting a person. When the person is detected, the sliding door 10 opens, that is, when viewed from the front, the tilted rail 5 is centered on the hinge 3 and the left side is raised. The driving device slides and opens on the inclined rail.

図2は図1と機構は同じであるが、扉10は開の状態である。扉10の閉から開までの動作は、人感センサー8の検知により駆動機構1(本案は電磁石)に電源が入り前記駆動機構1により上部傾斜レール5をヒンジ3中心に傾斜レール5を正面から見て右側を上げて、左側を下げて駆動装置6が前記傾斜レール5上を左へ滑動し連結シャフト7を介して前記扉10を開ける、前記扉10が全開になると戸当たりに設置のスイッチにより前記駆動機構1の電源がOFとなり同時に前記駆動機構2の電源がONとなり、前記上部傾斜レール5の右が下がり左が上がり前記駆動装置6は右の方向へ滑動し全閉となる又、全閉なった時点で戸当たりに設置のスイッチが働き前記駆動機構2の電源がOFFとなるが、閉めの開始後前記人感センサー8が検知すれば即前記駆動機構1がONとなり前記駆動機構2の電源がOFFとなる機構となっている。  FIG. 2 has the same mechanism as FIG. 1, but the door 10 is open. The operation from the closing to the opening of the door 10 is performed by detecting the human sensor 8 to turn on the power to the driving mechanism 1 (the electromagnet in this case), and the driving mechanism 1 causes the inclined rail 5 to be centered on the upper inclined rail 5 from the front. When the right side is viewed and the left side is lowered, the drive device 6 slides to the left on the inclined rail 5 and opens the door 10 via the connecting shaft 7. When the door 10 is fully opened, the switch is installed at the door. As a result, the power source of the drive mechanism 1 becomes OF and the power source of the drive mechanism 2 is turned on at the same time, the right of the upper inclined rail 5 falls and the left rises, and the drive device 6 slides in the right direction and is fully closed. When the door is fully closed, a switch installed in the door is operated and the power of the drive mechanism 2 is turned off. However, if the human sensor 8 detects after the start of closing, the drive mechanism 1 is immediately turned on and the drive mechanism is turned on. 2 Source has become a mechanism that turned OFF.

図5は床面にガイドレール12を設置し、前記ガイドレール12内に扉10下部のガイドローラー13を入れ前記扉10に対する風圧対策及び前記ガイドローラー13の回転により扉の開閉滑動を安定させる事が出来、又扉上部の吊車9は下部レール4上を水平に滑動するが、その動力源はヒンジ3の上に設けた上部傾斜レール5上を駆動装置6を滑動させ前記駆動装置6から扉10へ連結シャフト7を介して扉を開閉させる。
前記連結シャフト7は前記上部傾斜レール5上を前記駆動装置6の勾配のある走行により扉10の前記連結シャフト7受けは前記連結シャフト7のサイズより大きいシャフト受けを設け上部からの差込式とし又前記連結シャフト7は垂直とはならない為前記扉10の前記連結シャフト7受けはピン接合14とし傾斜にも対応できる工法とした。
In FIG. 5, a guide rail 12 is installed on the floor, and a guide roller 13 below the door 10 is placed in the guide rail 12 to stabilize the opening and closing sliding of the door by measures against wind pressure on the door 10 and rotation of the guide roller 13. The suspension wheel 9 at the upper part of the door slides horizontally on the lower rail 4, and its power source slides the driving device 6 on the upper inclined rail 5 provided on the hinge 3 and opens the door from the driving device 6. 10 to open and close the door via the connecting shaft 7.
The connecting shaft 7 is a plug-in type from above by providing a shaft receiver larger than the size of the connecting shaft 7 for receiving the connecting shaft 7 of the door 10 by running the drive device 6 on the upper inclined rail 5 with a gradient. In addition, since the connecting shaft 7 is not vertical, the receiving shaft 7 of the door 10 is connected to the pin joint 14 so that it can cope with inclination.

図6は電気配線図を示し内容は、通常扉(引戸)10は全閉状態であるがセンサー8の内外いずれかを検知するとR1リレーの作動により駆動機構1の電磁石が稼働し扉10は全開の状態になりLS(リミットスイッチ)が働き前記駆動機構1の電磁石電源がOFFとなると同時に駆動機構2の電磁石電源がONとなるが前記駆動機構2がONの状態でもセンサー8が検知すれば即前記駆動機構2の電磁石電源はOFFとなると同時に前記駆動機構1に電源が入り扉10は開方向となる、尚全閉状態でLSが働き前記駆動機構2の電源がOFFとなりセンサー8が検知するまでは前記駆動機構1、2の電磁石電源はOFFの状態である。  FIG. 6 shows an electrical wiring diagram. The content is that the normal door (sliding door) 10 is in a fully closed state, but when either the inside or outside of the sensor 8 is detected, the electromagnet of the drive mechanism 1 is activated by the operation of the R1 relay, and the door 10 is fully opened. LS (limit switch) is activated and the electromagnet power supply of the drive mechanism 1 is turned off and the electromagnet power supply of the drive mechanism 2 is turned on at the same time, but as soon as the sensor 8 detects even when the drive mechanism 2 is on. At the same time that the electromagnet power of the drive mechanism 2 is turned off, the power is turned on to the drive mechanism 1 and the door 10 is opened. In addition, LS is activated in the fully closed state, and the power of the drive mechanism 2 is turned off and the sensor 8 detects. Until then, the electromagnet power supply of the drive mechanisms 1 and 2 is in an OFF state.
