一方、開口部３を開口させる場合、開閉機７が作動して巻取体６が回転すると、開閉体５が巻取体６に巻き取られて上昇する。開閉体５は係合体15が係合受け体41に当接するまで上昇し、この上昇して巻き取られて略円筒状になった開閉体本体部11が収容ケース体30内に収容される（図１参照）。   On the other hand, when opening the opening 3, when the opening / closing machine 7 operates and the winding body 6 rotates, the opening / closing body 5 is wound around the winding body 6 and rises. The opening / closing body 5 is raised until the engaging body 15 comes into contact with the engagement receiving body 41, and the opening / closing body main body 11 which is wound up and is formed into a substantially cylindrical shape is accommodated in the accommodating case body 30 ( (See FIG. 1).

そして、開閉装置１のメンテナンスを行う場合には、開口部３を開口させた状態で、ねじ34を外し、下ケース部材35を上ケース部材31および側板部材32から取り外す。   When maintenance of the opening / closing device 1 is performed, the screw 34 is removed while the opening 3 is opened, and the lower case member 35 is removed from the upper case member 31 and the side plate member 32.

次いで、取付ねじ48を外した後、係合受け体41を取付部材42から取り外す。すなわち、係合受け体41を案内体21の上端部から取り外す。   Next, after the attachment screw 48 is removed, the engagement receiver 41 is removed from the attachment member 42. That is, the engagement receiver 41 is removed from the upper end portion of the guide body 21.

その後、開閉体５の幅木部12を所望量だけ一旦上方に持ち上げて移動させることにより、開閉体５の左右の挿入端部5a全体を左右の案内体21内から案内体21外に出す（図３および図４参照）、そして開閉体５等のメンテナンスを行う。なお、係合受け体41が損傷等した場合には、係合受け体41のみ新たなものに交換することも可能である。   Thereafter, the baseboard portion 12 of the opening / closing body 5 is once lifted upward and moved by a desired amount, whereby the entire left and right insertion end portions 5a of the opening / closing body 5 are brought out of the guide body 21 from the left and right guide bodies 21 ( 3 and FIG. 4), and maintenance of the opening / closing body 5 or the like is performed. When the engagement receiver 41 is damaged, it is possible to replace only the engagement receiver 41 with a new one.

メンテナンス終了後には、開閉体５の挿入端部5aを案内体21内に挿入した後、取付ねじ48を用いて係合受け体41を取付部材42に取り付け、その後、ねじ34を用いて下ケース部材35を取り付ける。   After the maintenance is completed, the insertion end 5a of the opening / closing body 5 is inserted into the guide body 21, and then the engagement receiving body 41 is attached to the mounting member 42 using the mounting screw 48, and then the lower case using the screw 34 The member 35 is attached.

そして、開閉装置１によれば、開口部３の開口時に係合体15と係合して開閉体５の開移動方向への移動を規制する係合受け体41が、案内体21に対して脱着可能となっているため、従来のようにガイドレールを外枠から取り外さなければならない場合に比べて、容易にメンテナンスができる。また、係合受け体41を室内空間から脱着でき、これにより係合受け体41が破損や経年劣化によって交換が必要となった場合でも安全に交換作業ができる。   According to the opening / closing device 1, the engagement receiving body 41 that engages with the engagement body 15 when the opening 3 is opened and restricts the movement of the opening / closing body 5 in the opening movement direction is detached from the guide body 21. Therefore, the maintenance can be easily performed as compared with the case where the guide rail has to be removed from the outer frame as in the prior art. In addition, the engagement receiver 41 can be detached from the indoor space, so that even when the engagement receiver 41 needs to be replaced due to breakage or deterioration over time, the replacement operation can be performed safely.

また、外枠22とガイドレール23とが一体化されているため、案内体21の構成がきわめて簡単で、施工時間の短縮化およびコスト低減等を図ることができる。   Further, since the outer frame 22 and the guide rail 23 are integrated, the structure of the guide body 21 is very simple, and the construction time can be shortened and the cost can be reduced.

さらに、係合受け体41が傾斜面60にて構成されたねじ頭逃し部59を有するため、開閉体５の下降時に係合体15の係合側面17が取付ねじ48の頭部48aに接触するのを避けることができ、開閉体５をスムーズに下降させることができる。   Further, since the engagement receiving body 41 has the screw head relief portion 59 constituted by the inclined surface 60, the engagement side surface 17 of the engagement body 15 contacts the head portion 48a of the mounting screw 48 when the opening / closing body 5 is lowered. Can be avoided, and the opening / closing body 5 can be lowered smoothly.

なお、上記実施の形態では、係合受け体41を取付部材42を介して案内体21に脱着可能に取り付けた構成について説明したが、例えば係合受け体41を取付部材42を介さずに案内体21に脱着可能に直接取り付けた構成でもよく、また例えば係合受け体41を収容ケース体30の下面部に脱着可能に取り付けた構成等でもよい。   In the above embodiment, the configuration in which the engagement receiver 41 is detachably attached to the guide body 21 via the attachment member 42 has been described. However, for example, the engagement receiver 41 is guided without the attachment member 42. For example, a configuration in which the engagement receiving body 41 is detachably attached to the lower surface portion of the housing case body 30 may be used.

また、例えば開口部３の幅寸法が大きい場合に用いられる脱着可能な案内体である中柱の上端部に、係合受け体41を脱着可能に取り付けた構成等でもよい。   Further, for example, a configuration in which the engagement receiver 41 is detachably attached to the upper end portion of the middle pillar, which is a detachable guide used when the width of the opening 3 is large, may be used.

さらに、案内体21は外枠22とガイドレール23とサッシ枠とを一体化したもの等でもよい。   Further, the guide body 21 may be one in which the outer frame 22, the guide rail 23, and the sash frame are integrated.

また、係合受け体41が案内体21に対して高さ位置を調整できるようにしてもよい。   Further, the height position of the engagement receiver 41 relative to the guide body 21 may be adjusted.

さらに、開閉装置１は、窓用シャッタ以外に、ガレージ用シャッタ装置、店舗用シャッタ装置、ブラインド装置、スクリーン装置等、或いはこれら装置のうちの同種または異種を複数並設したものでもよい。   Further, in addition to the window shutter, the opening / closing device 1 may be a garage shutter device, a store shutter device, a blind device, a screen device, or the like, or a plurality of the same or different types of these devices arranged in parallel.

また、開閉装置１は、開口部３の閉鎖時に開閉体５の幅木部12が下枠10に当接する構成には限定されず、例えば下枠を設けず、幅木部12を床面等の建物の躯体側に直接当接させる構成等でもよい。   Further, the opening / closing device 1 is not limited to a configuration in which the baseboard portion 12 of the opening / closing body 5 abuts on the lower frame 10 when the opening 3 is closed. The structure etc. which contact | abut directly on the building side of the building may be sufficient.

さらに、開閉体５の移動方向は上下方向には限定されず、上下方向に対して傾斜した傾斜方向や、水平方向等でもよい。   Further, the moving direction of the opening / closing body 5 is not limited to the vertical direction, and may be an inclined direction inclined with respect to the vertical direction, a horizontal direction, or the like.
