Shutter device

Abstract

(57)【要約】 【目的】 遮蔽体の側縁部を安定して支持でき、遮蔽体 の開閉動作の円滑化等が図れる遮蔽装置を提供する。 【構成】 一対ずつの側枠2a,2b及び端枠2c,2 dからなる方形の枠体2と、この枠体2の両側枠2a, 2b間に側枠2a,2bに沿って移動可能に掛け渡され た1本若しくは2本の可動枠3と、該可動枠3と一方の 端枠2cとの間若しくは両可動枠3間に掛け渡され、上 記枠体2の開口領域Hを開閉可能に遮蔽する折畳み可能 なプリーツ状の遮蔽体4と、該遮蔽体4の側縁部に適宜 間隔で配置されて遮蔽体4の折返し部4aを挟持する挟 持部16を有すると共に、上記側枠2a,2bに沿って 形成された軌条部7に移動可能に係止される係止部17 を有し、上記遮蔽体4の側縁部を側枠2a,2bに沿っ て移動可能に支持する支持体6とを備えている。これに より遮蔽体4の側縁部を安定して支持できる。
PURPOSE: To make smooth the shutter opening/closing motions by furnishing a framing body consisting of a pair of side frames and end frames, a shutter to set a movable frame between the two side frames and shuts the open region with a possibility of being opened and shut, a track and a pinch part to hold the folded-back part, and a support which supports the shutter. CONSTITUTION: When a mesh door is to be shut, a movable frame 3 is moved to the end frame 2d positioned opposingly while an open region H is reserved in between, and a pleat-form meshing 4 is stretched open so that the open region H is enclosed. When the mesh door is to be opened, the movable frame 3 is moved toward the end frame 2C on the opposite side, where the meshing 4 is shrunk and shut so that the open region H is spread open. A support 6 is positioned in the folded-back part of the meshing 14 and fixed in such a way as pinching. This permits the support 6 to make stable supporting of the side edge of the meshing 4 while a constant attitude is maintained without inclination or rotation associate with the opening/closing motions of the meshing 4. Thus the meshing 4 can be opened and closed smoothly. COPYRIGHT: (C)1996,JPO
