Description

  The present invention relates to a horizontal screen device for installation in an opening of a building. More specifically, the present invention relates to a method for changing the left and right sides of the screen, and a screen between a fixed frame and a movable rod. The present invention relates to a screen device in which the mounting direction of the attached screen unit can be freely selected.

  As disclosed in Patent Document 1, one end of a screen that can be expanded and contracted in a horizontal direction is connected to a fixed frame in a screen frame installed in a building opening, and the other end of the screen is opened and closed. When assembling the screen unit connected to the movable rod and freely opened and closed together with the receiving frame with which the movable rod comes into contact when the screen is stretched, the fixed frame and the receiving frame are attached to the screen frame with a hook-and-loop fastener. A device designed for the convenience of repair and replacement is already known.

  In a screen device such as a screen door attached to a sash window or the like as shown in Patent Document 1, a pair of side frames in the screen frame are formed by a frame member having a U-shaped cross section, and their openings In general, the fixed frame and the receiving frame are attached to the frame member of the screen frame by means of a hook-and-loop fastener. It is necessary to attach the frame to the inner bottom surface of the frame member having a U-shaped cross section, and as shown in Patent Document 1, the inner bottom surface of the frame member and the mounting surfaces of the fixed frame and the receiving frame The fastener pieces are fixed by bonding or the like, and are joined to each other.

  In general, the above-mentioned surface fastener has a relatively large joining force when it is joined, however, when the joined surface fastener is sequentially peeled from one end thereof, the joining surface is removed relatively easily. However, a very large force is required to peel off in a direction perpendicular to the fastener surface.

  However, when the fixing frame and the receiving frame are joined to the inner bottom surface of the frame member having a U-shaped cross section, both are joined on a relatively wide fastener surface, and both the joined frames are rigid such as metal. It is necessary to pull both in the direction orthogonal to the fastener surface when trying to separate them, so that a very large force is required for that purpose. In addition, there is a high possibility that a part will be damaged because a large force is applied between the two, and in particular, the fastening of the fastener part to the inner bottom surface of the fixed frame and the receiving frame and the frame member, etc. Otherwise, there is a high possibility that the adhesive portion of the hook-and-loop fastener will be peeled off, and there is a problem in letting the user attach and detach the screen unit etc. to the screen frame. That.

  On the other hand, the hook-and-loop fastener has a thickness of about 2 to 3 mm when a pair of fastener pieces are joined, and the hook-and-loop fastener is provided at a plurality of locations between the fixed frame and the receiving frame and the inner bottom surface of the frame member. When connected, there is a gap of about 2 to 3 mm between them, and a lot of space is formed between the loops of thin fibers and the entanglement of the hook-shaped member between the joint surfaces of the hook-and-loop fastener itself. When installing a screen for the purpose of avoiding the entry of insect screen doors and pollen, it is not only difficult to avoid the passage of insects and pollen, but also the characteristics of the hook-and-loop fastener itself. As described above, since the fastener pieces are joined not in a rigid manner but in a state having some flexibility, it is difficult to reliably seal the flow paths of the insects and pollen.

  Further, various dusts enter the gap due to the airflow flowing through the flow paths such as insects and pollen described above, and in particular, since the joint surface of the hook-and-loop fastener is formed in a filter shape, the dust is trapped in the inside. In many cases, particularly when rainwater or dew condensation water intervenes, the trapping is also remarkable. For this reason, once the hook-and-loop fastener is removed from the joined state, there is a problem that the joining force thereafter is remarkably reduced due to the dust or the like.
