Abstract: A screen device includes a screen retaining member defined by needle-shaped parts attached, in intervals, to a longitudinal base part which is bendable in a pivotally movable direction of each of plural guide units. In an attached condition of the screen retaining member, the longitudinal base part is supported between a rail part and a supporting piece of each of the guide units and all of the needle-shaped parts protrude inwardly between opposing side walls of each of the guide units.

Abstract: This electric screen device is provided with an electric motor that causes slidable screen mounting frame part(s) to automatically slide. Torque generated by rotation of a rotation shaft of the electric motor is transmitted to a tension member that is provided inside the screen mounting frame parts, that connects screen guiding frame parts to each other at free ends thereof, and that forms a loop. The tension member moves in a state of being hung around the folded portions which apply tension to the tension member. The slidable screen mounting frame part(s) automatically slide in association with movement of the tension member. Thus, the screen automatically opens and closes.

Wall portions (18) of the first rigid units are fitted in between the side wall portions of the second rigid units, and the upper slide guide frame portion intersects the lower slide guide frame portion in the interior of the screen mounting frame. Connection of the first rigid units can be released at an arbitrary position in the interior of the screen mounting frame when adjusting the length of the screen device (1), and the upper slide guide frame portion can be taken out from the screen mounting frame, so that an adjustment of the length in the field of installation is facilitated.

Abstract: In a screen device, a pair of vertical rails 24 arranged on the front and back sides of a screen 8 so as to oppose to each other are connected by connecting members 30 and are fixed between a pair of sliding guide frames 10a and 10b with the intermediary of the screen. The connected vertical rails are integrally slidable in the direction parallel to the direction of sliding movement of a screen mounting frame, so that the screen is restrained from being deflected even when it receives a wind pressure in the closed state when the width in the opening and closing direction is large.

Abstract: To provide a screen device which allows an easy length adjustment work configured in such a manner that when the size of first rigid units 24 which constitute an upper slide guide frame portion 15 is smaller than the size of second rigid units 17 which constitute a lower slide guide frame portion 16 and the upper slide guide frame portion and the lower slide guide frame portion are retracted in the interior of a screen mounting frame 10, side wall portions 18 of the first rigid units are fitted in between the side wall portions of the second rigid units, the upper slide guide frame portion intersects the lower slide guide frame portion in the interior of the screen mounting frame, connection of the first rigid units can be released at an arbitrary position in the interior of the screen mounting frame when adjusting the length of the screen device 1, and the upper slide guide frame portion can be taken out from the screen mounting frame, so that an adjustment of the length in the field of installation is facil

Abstract: A weight moving in a height direction interlocking with development and reception of a slide guide frame is provided, and the weight brakes reception of the slide guide frame owing to an increase in potential energy and promotes development of the slide guide frame owing to a decrease in potential energy, whereby an operating force is decreased, a feeling of operating a slide bar is made light, and the slide bar is decreased in sliding speed at the time of closing to achieve an improvement in safety.

Abstract: A shrinkable and extensible screen is mounted between a pair of screen-mounting frame portions arranged bilaterally to confront each other and at least one being slidably movable. A tension member extending through the screen for supporting it in shrinking and extending directions is routed in the screen-mounting frame portions. The tension member is extracted at the portion close to the central portion from the upper end portion of the slidably movable screen-mounting frame portions, to the outside on the side opposite to the screen mounting side.
