Sliding screen door

Abstract

The invention provides a sliding screen door having a net guide that moves in association with the opening and closing movement of a net, wherein the opening and closing operation of the screen door can be performed smoothly while providing a buffering effect with an adequate resistance, without hindering the opening and closing operability of a movable edge member, by enabling a reaction force, which is required for its bending, to be used as a buffering force against the operating force of the movable edge member, the net guide being formed by connecting guide pieces. In order to do so, a net guide 12 fed out from and drawn into the lower end of the vertical frame member 6 in association with the opening and closing operation of the net 4, is provided for guiding the lower end of the net 4. The net guide 12 is formed by connecting with a tape member 16 a number of guide pieces 14 formed substantially into a U-shape with a bottom portion 14a and a stabilizing portion 14b. The tape member 16 is inserted into the insertion devices 14c on the guide pieces 14 and the guide pieces 14 at both ends are fixed to the tape member 16.

Description

technical field [0001] The invention relates to a screen door which can be freely opened and closed by laterally pulling a gauze which is alternately folded in opposite directions and which can be unfolded freely. The lower end of the net leads out to the horizontal pull screen door of the gauze guide. Background technique [0002] For example, as disclosed in Japanese Patent No. 3007628, etc., the conventionally known screen door is to be alternately folded in opposite directions and the left and right ends of the gauze that can be expanded freely are installed on the vertical frame member of the screen door frame and used On the movable frame for switch operation, the above-mentioned gauze can be opened and closed by pulling the movable frame laterally, and there is a gauze guide in the screen door of the above-mentioned structure, and the gauze is closed while the above-mentioned gauze is closed. The net guide is pulled out from the lower end of any one of the vertical f...

AI Technical Summary

Problems solved by technology

As the resin constituting the above-mentioned gauze guide, it is necessary to use a resin that has sufficient strength against repeated bending and moderate resistance to bending, so there is a problem of material limitations.

[0004] Especially when the horizontally drawn screen door is used as an insect-proof screen door, since a part of the above-mentioned gauze guide, that is, on the anti-swing portion erected along the outer surface of the gauze, there are a plurality of bendable bottom parts. Notches, so this part forms a gap, and if the gap is enlarged, it may result in poor insect repellent effect

[0005] On the other hand, Japanese Patent Application Laid-Open No. 2000-145314 discloses a structure with a screen door that is sequentially connected to the above-mentioned gauze guides through the mutual cooperation of protrusions and holes. The unit is not only cumbersome, but also cannot generate a cushioning force against the operating force of the movable frame like the above-mentioned thermoplastic synthetic resin extruded material guide.
