Abstract:
1. A screen device comprising: a screen to be opened and closed sideward; a roller pipe to which one of left and right ends of the screen is attached, the roller pipe configured to be rotated by a resilient force of an integrated coil spring and wind the screen on an outer periphery thereof; a screen mounting frame being slidable in a direction of opening and closing of the screen with respect to the roller pipe fixed to a predetermined position, to which one end of the screen positioned on an opposite side from the end attached to the roller pipe is attached; and an upper slide guide frame portion disposed in the vicinity of an upper end of the screen and a lower slide guide frame portion disposed in the vicinity of a lower end of the screen, the upper slide guide frame portion being made up of a plurality of first rigid units each having a pair of side wall portions arranged so as to face each other and a bridging portion connecting both side wall portions with respect to each other by being coupled so as to be rotatable between adjacent ones of the first rigid units, the lower slide guide frame portion being made up of a plurality of second rigid units each having a pair of side wall portions arranged so as to face each other and a bridging portion connecting both side wall portions with respect to each other by being coupled so as to be rotatable between adjacent ones of the second rigid units, the upper slide guide frame portion and the lower slide guide frame portion both having flexibility and each having a free end at one end thereof, the free end being able to be retracted into and withdrawn from the interior of the screen mounting frame and, in contrast, when having been withdrawn from the screen mounting frame in association with the sliding movement of the screen mounting frame, the portion withdrawn from the screen mounting frame keeping their linearity, wherein the roller pipe includes a revolving shaft on which the coil spring is wound integrated therein, connected to a rotator rotatably disposed with respect to a stator connected to a lower end of the revolving shaft, and is rotatably refracted in a housing frame, wherein the stator includes a disc-shaped main body at a lower end thereof, and arcuate-shaped claws which project outward from an outer peripheral surface of the main body of the stator, wherein a hexagon socket is formed at a center portion of the main body of the stator upward from a lower surface of the main body of the stator, the hexagon socket allowing insertion of a hexagonal wrench and having a shape corresponding to an outside of the hexagonal wrench, wherein a cap member is detachably disposed at a lower end of the housing frame, an opening penetrating a main body of the cap member in a vertical direction of the main body of the cap member is formed at a center portion of the main body of the cap member, and the cap member is capable of having the revolving shaft, the coil spring and a connecting portion of the stator with the revolving shaft inserted through the opening, but is incapable of having the rotator and a main body of the roller pipe inserted through the opening, wherein holding portions are disposed on a lower surface of the main body of the cap member in a periphery of the opening so as to be arranged radially, the holding portions each having a holding space for receiving one of the claws in the interior thereof, the holding space being opened outward at one end on a side for receiving the claw and closed at the other end, wherein arcuate-shaped grooves having a shape corresponding to an outside shape of one of the claws are formed at the lower surface of the main body of the cap member adjacent to the holding portions, and a circular groove having a shape corresponding to an outside shape of the main body of the stator is formed at an inside of the arcuate-shaped grooves, and wherein an upper end of the revolving shaft is disposed at a midpoint of the roller pipe in a height direction of the roller pipe.
