  The drawings show an example of an embodiment of a screen device for a building opening according to the present invention. This building opening screen device is suitable for being installed inside the window sash 2 when the shoji 3 in the building opening 1 is an open window or a sliding window that opens outward. In the illustrated embodiment, an outer opening window is shown in which the shoji 3 opens to the outdoor side by rotating the handle 4. However, the present invention is not limited to this configuration.

  In this screen device, the screen 5 is attached to the indoor side of the window sash 2 of the building opening 1 so that the shoji 3 opens to the outdoor side. In this case, when the screen 5 is soiled by long-term ventilation, It is necessary to perform maintenance such as cleaning the screen or to easily replace the screen when it is damaged. Note that if the screen is separately stretched on the screen frame and attached to the window sash 2, the presence of the handle 4 or the like does not necessarily facilitate the attachment / detachment operation, and the field of view through the building opening 1 is limited. This is not desirable.

In order to presuppose the attachment of the screen 5 as described above, first, as shown in FIG. 2, the pair of left and right vertical frames 6 positioned on the indoor side of the window sash 2 are arranged at positions facing each other. A slit 6a is provided along the longitudinal direction, and an engagement bulge piece 5a provided along the left and right ends of the screen 5 is engaged inside the slit 6a so as to be slidable up and down along the slit 6a. I am letting. As the bulging part piece 5a, it is desirable to use a half of a fastener used for joining ends of a cloth or the like.
And the said screen 5 attaches the 1st and 2nd holding members 10 and 20 to the upper and lower ends so that it can be removed so that it may be described in detail below, and the screen 5 is attached by those operations so that it may mention later. It can be easily pulled out or removed along the slit 6a of the vertical frame 6.

  The first and second holding members 10 and 20 that are detachably attached to the upper and lower ends of the screen 5 will be described in detail. First, the first holding member 10 provided on the upper end of the screen 5 in the illustrated embodiment. 1, 4, and 7, an opening cover 11 that forms a part of the horizontal frame 7 on the upper portion of the window sash 2 in the building opening 1 is formed on the inner surface of the opening cover 11. The upper end of the screen 5 is held. The opening cover 11 covers the accommodating portion of the guide bar 13 for turning the screen 5 disposed in the upper horizontal frame 7. The opening cover 11 is removed and the opening cover 11 is removed. As shown in FIG. 5, the screen 5 held on the inner surface can be led out, and the guide bar 13 can also be removed from the opening of the horizontal frame 7 formed thereby if necessary.

The detachable attachment of the upper end of the screen 5 to the opening cover 11 is provided with a bulging part piece 5b similar to the bulging part piece 5a for engaging the side end of the screen 5 also on the upper end of the screen 5. It is attached to the inner surface of the opening cover 11 on the inner side of the slit 11b at the mouth of the mounting groove 11a provided in the width direction of the screen 5 by insertion from the end of the slit 11b. However, the present invention is not limited to this. For example, by using hook-and-loop fasteners, the hook-and-loop fastener pieces to be bonded to each other are attached to the inner surface of the opening cover 11 and the upper end of the screen 5 and bonded to each other by simple means such as insertion and sticking. Means that can be connected in a predetermined positional relationship over the entire length are suitable.
In the illustrated embodiment, the mounting groove 11a is integrally provided in the opening cover 11, but the mounting groove can be provided by attaching another member.

  The guide bar 13 is disposed on an extension of the screen 5 stretched between the slits 6a of the pair of vertical frames 6 so that a cylindrical guide surface of the peripheral surface thereof is positioned. When the screen 5 inserted between the six slits 6a is pulled out, the screen 5 is smoothly turned inside the horizontal frame 7. As can be seen from FIGS. 3 and 5, the guide bars 13 are supported at both ends with support shafts 13 a provided at both ends of the guide bars 13 being positioned at the upper ends of the vertical frames 6 of the window sash 2. The bearing 7a of the frame 7 is supported rotatably by being dropped into the receiving groove 14 with the upper end opened.

  On the other hand, the second holding member 20 disposed at the lower end of the screen 5 is arranged in a horizontal position below the window sash 2 between the pair of left and right vertical frames 6 as clearly shown in FIGS. The frame 8 is configured to be detachably held, and is configured by a cross beam 21 whose both ends are slidably guided along a sliding groove 6b provided in the longitudinal direction of the pair of left and right vertical frames 6. The sliding groove 6b of the vertical frame 6 is provided with the slit 6a for engaging the bulged piece 5a at the left and right side ends of the screen 5 at the groove bottom.

  In order to detachably attach the screen 5 to the horizontal beam 21, a bulging part piece 5 b similar to the upper end of the screen 5 described above is provided at the lower end of the screen 5, and this is placed on the upper surface of the horizontal beam 21 in the longitudinal direction It is made to attach to the inner side of the slit 21b in the mounting groove 21a provided along the edge by insertion from the end of the slit 21b.

However, in order to make the screen 5 detachable from the horizontal rail 21 more easily, for example, the bulging part piece 5b is folded in two so as to be sandwiched from below, and is engaged and held inside. The screen end holding member having a tendency to expand is used, and known means (for example, Japanese Patent Application Laid-Open No. 2005-48437) is used to push the screen end holding member into the mounting groove 21a of the horizontal rail 21 and elastically lock it. The screen end holding member 22 of the publication can also be employed. The same applies to the case where the upper end of the screen 5 is attached to the first holding member 10.
Further, a hook-and-loop fastener can also be used for fixing the end of the screen 5 to the horizontal rail 21 as in the case of the first holding member 10.

  In order to hold the horizontal beam 21 that can be guided vertically along the sliding groove 6 b of the vertical frame 6 to the lower horizontal frame 8 when the screen 5 is stretched, the horizontal frame 21 is pushed into the horizontal frame 8. 6 is provided on the side surface of the horizontal rail 21 as shown in FIGS. 6A to 6C. By selectively elastically engaging the formed positioning convex portion 21c with any of a plurality of engaging protrusions 8b formed on the inner surface of the concave groove 8a, a plurality of tension levels of the screen 5 can be obtained. It is provided with a function that can be changed stepwise to hold the crosspiece 21. Further, the convex portion 21c for positioning the horizontal rail 21 is elastically engaged with the engaging protrusion 8b in the concave groove 8a of the lower horizontal frame 8, so that the convex portion 21c of the horizontal rail 21 is provided. When a plurality of elastic pieces 21d that elastically protrude are provided on the side opposite to the side provided with the side rail 21 and the cross rail 21 is press-fitted into the groove 8a, the protrusion 21c is engaged with the groove in the groove 8a. It is elastically pressed toward the mating protrusion 8b.

  As shown in FIG. 8, the screen 5 attached to the opening cover 11 can be pulled out from the upper part of the window sash 2, and is removed from the concave groove 8 a in the lower horizontal frame 8 by this drawing. When the horizontal beam 21 is pulled by the screen 5 and reaches the upper end of the window sash 2, the horizontal beam 21 is placed there in order to make it possible to perform maintenance such as easy cleaning in the state shown in FIG. It is formed so that it can be locked once. The horizontal rail 21 is locked by bringing the horizontal rail 21 into contact with a locking portion 7 b formed on a part of the horizontal frame 7 of the window sash 2. The horizontal rail 21 in contact with the locking portion 7b is taken out from the sliding groove 6b when the guide rail 13 is taken out from the opening formed by opening the opening cover 11 and the upper portion of the horizontal rail 21 is removed. By tilting toward the room side, both ends of the horizontal beam 21 are separated from the sliding groove 6b, and the horizontal beam 21 is formed so as to bypass the locking portion 7b and to be released to the outside.

  In the screen device having the above-described configuration, the opening cover 11 and the horizontal rail 21 constituting the first and second holding members 10 and 20 may be attached to either side of the upper and lower ends of the screen 5 in the building opening 1. For example, the opening cover 11 is provided in the horizontal frame 8 at the lower part of the building opening 1, the guide bar 13 is provided in the horizontal frame 7, and the horizontal bar 21 is installed at the side of the upper part of the building opening 1. It is also possible to adopt a configuration in which the frame is held by the frame and guided by the sliding grooves 6b of the pair of left and right vertical frames 6 so as to be slidable in the vertical direction.

  In such a screen device, the screen 5 can be slid up and down along the longitudinal slit 6a provided in the pair of left and right vertical frames 6, so that it can be used together with the one holding member 10 or 20 or the holding member. The screen 5 can be removed from the screen, and the screen can be pulled out in any direction for cleaning, or the damaged screen can be extracted and replaced with a new one. The screen 5 is cleaned by pulling the screen 5 in either the upper or lower direction as described above, and when the horizontal beam 21 reaches the opposite vertical end of the building opening, the horizontal beam is temporarily engaged there. In a stopped state, the screen side of the screen can be cleaned, and therefore maintenance such as cleaning can be performed very easily without substantially removing the screen 5.
