Screen installations and doors and windows

Abstract

The present invention relates to a screen device and a door-window set, and specifically relates to a winding screen window by which the increase in construction space and the reduction in effective open area of a frame, which is inside equipped with an outer slide window, are inhibited. The winding screen window (5) comprises a winding shaft (50); a screen (51) which is pullably winded on the winding shaft (50); a screen frame (70) which is provided with an approximately cylinder shaped accommodating shell (71) for accommodating the winding shaft (50), and an upper rail (823) and a lower rail (843) which are configured to extend from two ends of the accommodating shell (71) in a direction substantially orthogonal to the winding shaft (50) and guide two end edges of the screen in a smooth sliding manner; and fittings (90) which are configured to be attached to the frame and used for fixing the accommodating shell (71), the upper rail (823) and the lower rail (843) to the outer surface of the frame separately.

Description

Technical field [0001] The invention relates to a net screen device and doors and windows. Background technique [0002] Conventionally, among doors and windows such as various windows, there is known a screen device that can be opened and closed freely left and right or up and down and can wind a screen such as an insect screen (for example, refer to Patent Document 1). [0003] The horizontal drawing screen as a screen device described in Patent Document 1 includes: a winding box attached to a side frame of a window frame; an insect-proof net wound by a winding shaft in the winding box; The movable lattice at the end of the net; and a pair of upper and lower guide rails that slidably guide the insect-proof net and the upper and lower ends of the movable lattice. [0004] The horizontal drawing screen is arranged to be clamped by the upper frame and the lower frame of the window frame. [0005] Prior art literature [0006] Patent Document 1: Japanese Patent Laid-Open No. 2001-20639....

AI Technical Summary

Problems solved by technology

[0007] However, in the structure described in Patent Document 1, since the horizontal-drawing screen is arranged to be sandwiched by the upper frame and the lower frame of the window frame, when the horizontal-drawing screen is installed in an embedded manner, for example, it is necessary to Secure construction space for recessed installation

In addition, since the winding box is installed on the inner side of the opening of the window frame, the effective opening area of ​​the window frame becomes smaller.
