Slide guide frame portion of screen device

摘要

In a side wall portion of a rigid unit which forms a slide guide frame portion, a depressed portion is formed in one approximately half portion, a through hole is formed in the other approximately half portion, and a protrusion is provided adjacent to the through hole inside the substantially center portion. In the depressed portion, a shaft protruding toward the outside is provided in the substantially center portion, and a notch portion cut in a height direction of the rigid unit is formed from the substantially center portion of the depressed portion to one end portion of the side wall portion. Adjacent two rigid units are connected by a shaft which is inserted into the through hole from the inside, and one unit is freely rotated with respect to the other unit within a range in which the protrusion abuts on one end and the other end of the notch portion.

主权项

1. A sliding screen device comprising:
a pair of hollow screen mounting frame portions configured to be disposed to face each other in which at least one of the pair of screen mounting frame portions is capable of sliding; a screen configured to be attached between the pair of hollow screen mounting frame portions to be freely developed; and a slide guide frame portion configured to be disposed in a vicinity of either end portion of the screen other than opposite ends where the screen is attached to the pair of hollow screen mounting frame portions, wherein the slide guide frame portion has flexibility, at least one end of the slide guide frame portion serving as a free end and is capable of being stored in and drawn out of the slidable one of the pair of screen mounting frame portions, and when the slide guide frame portion is drawn out of the slidable one of the pair of screen mounting frame portions as the slidable one of the pair of screen mounting frame portion slides, a drawn-out portion of the slide guide frame portion has linearity, wherein the slide guide frame portion comprises a plurality of rigid units, each of the plurality of rigid units including a pair of side wall portions disposed to face each other and a bridge portion linking both of the pair of side wall portions from a substantially center portion of the pair of side wall portions to one end portion of the pair of side wall portions, in which adjacent ones of the plurality of rigid units are rotatably connected to each other, wherein the side wall portion comprises a depressed portion which is depressed in a width direction of the respective one of the plurality of rigid units is formed in an approximately half portion from the substantially center portion to the one end portion, a through hole which is made in the width direction of the respective one of the plurality of rigid units formed in the approximately half portion from the substantially center portion to the other end portion, and a protrusion provided adjacent to the through hole inside the substantially center portion, wherein the depressed portion comprises a shaft protruding toward an outside direction provided in the substantially center portion, and a notch portion in a height direction of the respective one of the plurality of rigid units formed from the substantially center portion of the depressed portion to the one end portion of the side wall portion, and wherein the plurality of rigid units are connected such that the shaft of one of the plurality of rigid units is inserted into the through hole of an adjacent one of the plurality of rigid units from an inside position, and the adjacent one of the plurality of rigid units is freely rotated with respect to the one of the plurality of rigid units within a restricted range of rotational motion in which the protrusion abuts against on one end and the other end of the notch portion.
