Description

  The present invention relates to a horizontally-drawing screen device for mounting on an opening of a building for the purpose of dust prevention, light shielding, heat insulation, insect prevention and the like.

In a horizontal pull type screen device attached to a building opening formed by being surrounded by upper and lower horizontal frames and left and right vertical frames, a fixed rod fixed to the vertical frame, a movable rod that is slidable along the horizontal frame, A large number of ridges having substantially the same width are formed by alternately folding back in the opposite direction, and a pleated screen having both ends held between the fixed ridge and the movable ridge, and the movable ridge is slid As described in Patent Document 1 and Patent Document 2, the screen is configured to be able to open and close the building opening by expanding and contracting the screen into an accordion shape. .
In this type of screen device, in order to ensure a stable expansion / contraction operation of the screen and to prevent entry of small insects, dust, etc. from the gap, at least above the upper and lower horizontal frames of the building opening. A guide frame provided with a guide groove having a substantially U-shaped cross section is disposed on the horizontal frame, and the upper end of the movable rod is inserted into the guide groove and is slidably supported. In general, the upper end of the guide is also disposed in the guide groove.

By the way, in the pleated screen, the angle of the crease formed by the adjacent ridges changes according to the expansion / contraction state, so that the thickness in the front-rear direction, that is, each crease arranged on the one surface side is simultaneously changed. The distance between the surface including the surface and the surface including each fold line arranged on the other surface side also changes. The thickness of the screen is maximized when the screen is most contracted, and is approximately equal to the width of each ridge. Therefore, in the conventional screen device, considering the change in the thickness of the screen, the opening width of the guide groove of the guide frame is equal to or larger than the width of the ridge, which is the maximum thickness of the screen. Is also formed large.
Therefore, in such a conventional screen device, the difference between the opening width of the guide groove and the thickness of the screen becomes large in the state where the screen having the smallest screen thickness is expanded to the maximum. There was a problem that small insects, dust and the like easily entered from the gaps between them. Also, from the viewpoint of material cost and design, it is desirable that the width of the guide frame is smaller. However, if the width of the guide frame is substantially determined by the opening width of the guide groove, the guide frame described above is used. It is desirable that the groove opening width is smaller.
