Description

本発明は、オーバーヘッドドアを含むシャッター装置、ドア、雨戸を含む引戸、窓、ロールスクリーン、ブラインド、オーニング装置、門扉、ゲート等の開閉装置における施錠構造に関し、特にシャッター装置に適用するのに好適な開閉装置の施錠構造に関するものである。   The present invention relates to a shutter device including an overhead door, a door, a sliding door including a shutter, a window, a roll screen, a blind, an awning device, a gate, a gate, and the like, and is particularly suitable for application to a shutter device. The present invention relates to a locking structure of an opening / closing device.

従来、この種の発明には、躯体開口部を開閉する開閉体と、該開閉体の幅方向の端部を開閉方向へ案内するように立設されたガイドレールと、該開閉体を閉鎖方向へ引っ張るための引き手部材とを備え、開放状態にある前記開閉体を前記引き手部材により引っ張ることで閉鎖方向へ移動させて閉鎖状態にし、その閉鎖状態にある前記開閉体の幅方向の端部から鍵バー(ラッチバー等と呼称される場合もある)を突出させ、該鍵バーを前記ガイドレール内に係合させることで、前記開閉体を外部から開放できないようにしたものがある(例えば、特許文献1参照。)。   Conventionally, this kind of invention includes an opening / closing body that opens and closes a housing opening, a guide rail that is erected so as to guide an end of the opening / closing body in the opening / closing direction, and the opening / closing body in a closing direction. A pulling member for pulling the opening and closing the opening / closing body in the open state by pulling the opening / closing body in the closing direction by pulling the opening / closing body in the closed state. A key bar (sometimes called a latch bar or the like) is protruded from a portion, and the key bar is engaged with the guide rail so that the opening / closing body cannot be opened from the outside (for example, , See Patent Document 1).

しかしながら、上記従来技術によれば、上記引き手部材は、上記開閉体を閉鎖方向へ引っ張るためにしか用いられていない上、上記開閉体と別体の棒状に形成された態様である場合もあり、この別体の態様である場合には、上記開閉体から外された状態の時に、紛失してしまうおそれがあった。
また、近年では、防犯性を高めるために、施錠機構を二重に具備することが求められているが、上記従来技術に用いられる施錠機構は、上記鍵バーを出没させるためにリンク機構やスプリング等を用いているため、構造が複雑で、製造時間も比較的多く費やしていた。そのため、上記構造の施錠機構を二重に具備することは、開閉装置をより複雑化する上、コストアップの要因となるため、敬遠されがちであった。
特開2000−27507号公報
However, according to the prior art, the pulling member is used only for pulling the opening / closing body in the closing direction, and may be in a form formed as a separate rod from the opening / closing body. In the case of this separate aspect, there is a risk of losing when it is removed from the opening / closing body.
Further, in recent years, in order to improve crime prevention, it is required to have a double locking mechanism. However, the locking mechanism used in the above-described prior art is a link mechanism or a spring to allow the key bar to appear and disappear. Etc., the structure was complicated and the manufacturing time was relatively large. For this reason, the double provision of the locking mechanism having the structure described above tends to make the switchgear more complicated and increase costs, and thus tends to be avoided.

被係合部材41は、上記被係合部材11aの上面部11aと略平行に配置される略板状の係合片部41aを有する。
そして、この係合片部41aには、上記被係合部材11aの挿通孔11a11と略同様に、引き手部材20の引張り用係合部21を開閉体開閉方向(図示例によれば上下方向)へ貫通して挿入するように、開閉体幅方向の長孔状に形成された挿通孔41a1を有する。
The engaged member 41 includes a substantially plate-like engaging piece portion 41a disposed substantially parallel to the upper surface portion 11a of the engaged member 11a.
The engaging piece portion 41a has a pulling engagement portion 21 of the pulling member 20 in an opening / closing body opening / closing direction (in the vertical direction according to the illustrated example), similar to the insertion hole 11a11 of the engaged member 11a. The insertion hole 41a1 is formed in the shape of a long hole in the opening / closing body width direction so as to penetrate through and into the opening / closing body.

上記構成の施錠構造A1によれば、引き手部材20により開閉体10を閉鎖方向へ引っ張る際には、引き手部材20の引張り用係合部21が、開閉体10の閉鎖方向の端部側において開閉体幅方向へ突出する部位(図示例によれば符号aまたは符号bに示す部位等)に掛けられ、該引き手部材20が手等によって下方へ引かれることで、開閉体10が閉鎖される。   According to the locking structure A1 having the above-described configuration, when the opening / closing body 10 is pulled in the closing direction by the pulling member 20, the pulling engagement portion 21 of the pulling member 20 is connected to the end of the opening / closing body 10 in the closing direction. , The opening / closing body 10 is closed when the pulling member 20 is pulled downward by a hand or the like. Is done.

また、閉鎖状態の開閉体10を施錠する際には、引き手部材20の引張り用係合部21側が、開閉体10に一体的な上記係合片部11a1の挿通孔11a11と、下枠40に一体的な上記係合片部41aの挿通孔41a1との双方に挿入される(図1及び図2参照)。そして、引き手部材20は、施錠用係合部22を開閉体10側の係合片部11a1に当接させる。
なお、前記挿入の際、略フック状の引張り用係合部21の向きが、長孔状の被係合部材11a及び係合片部41aの長手方向の向きに合わせられる。
Further, when locking the closed opening / closing body 10, the pulling engagement member 21 side of the pulling member 20 is inserted into the insertion hole 11 a 11 of the engagement piece 11 a 1 integral with the opening / closing body 10, and the lower frame 40. Are inserted into both of the insertion holes 41a1 of the engaging piece portion 41a integrated with each other (see FIGS. 1 and 2). The pulling member 20 brings the locking engagement portion 22 into contact with the engagement piece portion 11a1 on the opening / closing body 10 side.
At the time of the insertion, the orientation of the substantially hook-shaped pulling engagement portion 21 is matched with the longitudinal direction of the elongated hole-like engaged member 11a and the engagement piece portion 41a.

そして、前記挿入の後、引き手部材20は、軸心を中心にして回動(図示例によれば角度略90度回動)されることで、下枠40側の被係合部材41の挿通孔41a1から抜けないように、引張り用係合部21を係合片部41aに係合させる。   After the insertion, the pulling member 20 is rotated about the axis (rotating approximately 90 degrees according to the illustrated example), so that the engaged member 41 on the lower frame 40 side is engaged. The pulling engagement portion 21 is engaged with the engagement piece portion 41a so as not to come out of the insertion hole 41a1.

したがって、引き手部材20は、引張り用係合部21と係合片部41aとの係合により、開閉体開放方向へ移動不能にされる。
また、開閉体10は、被係合部材11aを、移動不能な状態の前記引き手部材20の施錠用係合部22に当接させることで、開閉体開放方向へ移動不能にされ、開閉体開閉方向へ移動することのない施錠状態となる。
また、開錠の際には、引き手部材20を、軸心を中心にして回動(図示例によれば角度略90度回動)することで、引張り用係合部21を挿通孔41a1及び挿通孔11a11へ挿通可能にし、その後に、この引き手部材20を、被係合部材11a及び被係合部材41から引き抜けばよい。
Therefore, the pulling member 20 is made immovable in the opening / closing body opening direction by the engagement between the pulling engagement portion 21 and the engagement piece portion 41a.
Further, the opening / closing body 10 is made immovable in the opening / closing body opening direction by bringing the engaged member 11a into contact with the locking engagement portion 22 of the pulling member 20 in a non-movable state. The locked state does not move in the opening / closing direction.
Further, at the time of unlocking, the pulling engagement member 21 is rotated about the axis (rotating approximately 90 degrees according to the illustrated example), whereby the pulling engagement portion 21 is inserted into the insertion hole 41a1. Then, the handle member 20 may be inserted into the insertion hole 11a11, and then the pulling member 20 may be pulled out of the engaged member 11a and the engaged member 41.

なお、上記施錠構造A1によれば、開閉体10の閉鎖方向の端部側における開閉体幅方向の中央側に配設されて、引き手部材20を開閉体10の閉鎖方向の端部と下枠40とにわたって係合させるようにしたが、図3に示す施錠構造A2のように、同引き手部材20を開閉体10の幅方向の端部とガイドレール30とにわたって係合させるようにすることも可能である。   Note that, according to the locking structure A1, the pulling member 20 is disposed on the center side in the opening / closing body width direction on the end side in the closing direction of the opening / closing body 10 so that the pulling member 20 is located below the end in the closing direction of the opening / closing body 10. Although engaged with the frame 40, the pulling member 20 is engaged with the end of the opening / closing body 10 in the width direction and the guide rail 30 as in the locking structure A2 shown in FIG. It is also possible.

この施錠構造A2は、開閉体10の内面に、断面略L字アングル状の被係合部材50を、開閉体開閉方向に沿う向き(図示例によれば略垂直となる向き)に固定している。
被係合部材50は、開閉体10の内方(室内方向)へ略垂直状に突出する略板状の係合片部51に、引き手部材20の引張り用係合部21を開閉体幅方向(図示例によれば略水平方向)へ貫通し挿入できるように、開閉体厚さ方向の長孔状に形成された挿通孔51aを有する。
また、ガイドレール30における開閉体10側の部位には、前記挿通孔51aと略同様に、引き手部材20の引張り用係合部21を開閉体幅方向へ貫通し挿入可能なように、開閉体厚さ方向に長孔状に形成された挿通孔31を有する。
In this locking structure A2, the engaged member 50 having a substantially L-shaped cross section is fixed to the inner surface of the opening / closing body 10 in a direction along the opening / closing direction of the opening / closing body (in the illustrated example, a substantially vertical direction). Yes.
The engaged member 50 includes a substantially plate-like engagement piece portion 51 that protrudes in a substantially vertical direction inwardly (in the room direction) of the opening / closing body 10, and the pulling engagement portion 21 of the pulling member 20. There is an insertion hole 51a formed in the shape of a long hole in the opening / closing body thickness direction so that it can penetrate and be inserted in the direction (substantially horizontal direction in the illustrated example).
Further, in the portion of the guide rail 30 on the opening / closing body 10 side, substantially the same as the insertion hole 51a, the pulling engagement portion 21 of the pulling member 20 is penetrated in the opening / closing body width direction so as to be opened / closed. It has the insertion hole 31 formed in the shape of a long hole in the body thickness direction.

この施錠構造A2によれば、開閉体10が施錠される際、引き手部材20の引張り用係合部21側が、開閉体10に一体的な上記係合片部51の挿通孔51aと、ガイドレール30の挿通孔31との双方に挿入される(図3参照)。
引き手部材20は、軸心を中心にして回動(図示例によれば角度略90度回動)されることで、引張り用係合部21をガイドレール30内面に係合させる。そして、この係合により、引き手部材20は、ガイドレール30の挿通孔31から容易に抜けてしまうことがない状態となる。
According to this locking structure A <b> 2, when the opening / closing body 10 is locked, the pulling engagement member 21 side of the pulling member 20 is connected to the insertion hole 51 a of the engagement piece portion 51 integral with the opening / closing body 10 and the guide. It is inserted into both the insertion hole 31 of the rail 30 (see FIG. 3).
The pulling member 20 is rotated about the axis (in the illustrated example, the angle is approximately 90 degrees) to engage the pulling engagement portion 21 with the inner surface of the guide rail 30. And by this engagement, the pulling member 20 will be in the state which is not easily removed from the insertion hole 31 of the guide rail 30.

よって、前記状態の開閉体10は、外部等から開放方向の力が加えられた際、上記のように串刺し状に係合された引き手部材20の剪断応力により、開閉体開閉方向へ移動されてしまうのを阻む。   Therefore, the opening / closing body 10 in the above state is moved in the opening / closing body opening / closing direction by the shear stress of the pulling member 20 engaged in a skewered manner as described above when a force in the opening direction is applied from the outside or the like. To prevent it.

なお、この施錠構造A2の場合、前述したように、引き手部材20の剪断応力により開閉体10の移動を阻むようにしているため、挿通孔31及び挿通孔51aは、引張り用係合部21を挿通可能な孔であれば長孔でなくてもよい。
しかしながら、引き手部材20が容易に抜けてしまうことがないようにするためには、上記態様のように、挿通孔31及び挿通孔51aを長孔にして、引き手部材20を回動させ係合させるようにする方が好ましい。
また、上記施錠構造A2は、開閉体10の幅方向の一端側のみを、引き手部材20によりガイドレール30に係合させるものであるため、防犯性の観点からは、上記施錠構造A1のように、開閉体10の幅方向の中央側を引き手部材20により下枠40に係合させるようにした態様の方が好ましい。
In the case of this locking structure A2, as described above, since the opening / closing body 10 is prevented from moving by the shear stress of the pulling member 20, the insertion hole 31 and the insertion hole 51a are inserted through the pulling engagement portion 21. If it is a possible hole, it may not be a long hole.
However, in order to prevent the puller member 20 from being easily pulled out, the puller member 20 is rotated by rotating the puller member 20 with the insertion hole 31 and the insertion hole 51a as long as in the above embodiment. It is preferable to combine them.
Moreover, since the said locking structure A2 engages only the one end side of the width direction of the opening-and-closing body 10 with the guide rail 30 by the pulling member 20, from the viewpoint of crime prevention, it looks like the said locking structure A1. In addition, a mode in which the center side in the width direction of the opening / closing body 10 is engaged with the lower frame 40 by the pulling member 20 is preferable.

次に、図4乃至6に示す施錠構造A3について説明する。なお、この施錠構造A3において、上記施錠構造A1と略同様の部位については、上記施錠構造A1と同一の符号を用いることで重複する詳細説明を省略する。   Next, the locking structure A3 shown in FIGS. 4 to 6 will be described.
