Abstract:
1. A horizontal-pulling roll screen door, comprising: a screen door frame having a side frame mountable on one of a pair of opening side frames forming a building opening frame and extending in a vertical direction, an upper rail mounted on an opening upper frame forming the building opening frame and extending in a lateral direction, and a movable stile having an upper end slidably supported by the upper rail such that horizontal pulling is performed on the movable stile so the stile moves between the pair of the opening side frames; a winding shaft accommodating a coil-state winding spring therein and rotatably supported around a vertical axis of the winding shaft in the movable stile; a net extended between the side frame and the movable stile and wound up by an urging force of the winding spring around the winding shaft such that the net can be opened/closed by a horizontal pulling of the movable stile, wherein the movable stile includes a case accommodating the winding shaft, and first and second caps supporting the winding shaft rotatably around the vertical axis of the winding shaft, the first and second caps being detachably mounted at both upper and lower ends of the case in the vertical direction such that the first and second caps are interchangeable, the first cap being slidably supported by the upper rail, the movable stile accommodates an intermediate support member mountable on the first or second cap detachably and unrotatably around the vertical axis of the winding shaft, and a connecting cylindrical shaft mounted on a first end of the winding shaft in a direction of the vertical axis of the winding shaft relatively unrotatably around the vertical axis of the winding shaft and arranged on an outer circumference of the intermediate support member, a lock mechanism is provided between the connecting cylindrical shaft and the intermediate support member such that the connecting cylindrical shaft is rotatable around a vertical axis of the intermediate support member in an unlocked state and the connecting cylindrical shaft is unrotatable around the vertical axis of the intermediate support member in a locked state, a first end of the winding spring in a direction of the vertical axis of the winding shaft is mounted on the intermediate support member unrotatably around the vertical axis of the winding shaft and a second end of the winding spring in the direction of the vertical axis of the winding shaft is mounted to the winding shaft relatively unrotatably around the vertical axis of the winding shaft, the lock mechanism has a plurality of recess portions provided on the outer circumference of the intermediate support member in a circumferential direction, and a lock lever rotatably supported by a support pin in an opening provided at the connecting cylindrical shaft between a locked position and an unlocked position, and an engagement portion is provided in the lock lever to be engaged with any of the plurality of recess portions by rotational movement of the lever to the locked position and unengaged from the plurality of recess portions by rotational movement of the lever to the unlocked position.
