Screen device

Abstract

A screen device, comprising a screen guide simple in structure, stable in operation, and formable in a linear rail shape in a drawn-out state. The screen guide (12) further comprises a large number of guide blocks (14) formed in a generally U-shape by a bottom part (14a) along the end part of a screen (4) and a vertical wall part (14b) along the outer surface of the screen. A through hole (14c) is formed along the tip part of the vertical wall part, a series of wire member (16) is passed through the through hole, and when the screen guide is drawn out along the end part of the screen, the continuously connecting surfaces of the adjacent guide blocks (14) are brought into contact with each other.

Description

technical field [0001] The present invention relates to a curtain device, the curtain device has a curtain guide device for guiding the end of the curtain along the opening and closing direction, and more specifically, the curtain device has the following The curtain guide device is used in curtains such as building doors and windows, partitions, and curtains such as screen windows. With the opening and closing of the curtain, the curtain guide device is installed from at least one of the frame members installed at both ends of the curtain in the direction of opening and closing. It is bent in and out of the interior, and the curtain guide is led out along the end of the above-mentioned curtain in the tensioned state, thereby guiding the end of the curtain. Background technique [0002] There is a curtain device, which has a curtain guide device for guiding the end of the curtain. With the opening and closing of the curtain, the curtain guide device is installed in the openi...

Problems solved by technology

[0006] However, in the above-mentioned curtain guide device, when an unexpected strong wind or other external force acts on the screen, the screen guide device will be blocked by the screen guide at the part of the screen guide device linearly derived from the frame member. The lower end of the net pushes and may bend laterally in the horizontal direction

[0007] In addition, in the above-mentioned mesh guide device, the reverse bending of the mesh guide device (upward warping relative to the ground) is suppressed by means of the belt-shaped member connecting the guides, but the mesh guide device is stretched over a relatively wide range. In the case of netting, that is, in the state where the net guide device is drawn out for a long time, if the housing operation of the net is carried out through the movable frame with a large force, the net will be opposed in the direction of introduction of the frame member. The guiding device produces a large force, so that the screen guiding device bends laterally, and the screen guiding device may, contrary to the usual situation, be bent upwards into a convex shape and partially upturned
