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.

As shown in FIG. An operating rod 16a is attached to the square shaft 16 so as to penetrate the long hole 11c on the side wall of the shaft hole 11b from the side surface thereof and project to the outer surface of the cylindrical member 11 on the side where the screen 5 does not contact. And the operation element 16b which slides the outer surface of the cylindrical member 11 is attached to the front-end | tip. The long hole 11c is movable along the shaft hole 11b in a range between a position where the square shaft 16 can be sufficiently inserted into the square hole 14b of the support portion 14 and a position where the square hole 14b is completely escaped. Is. Accordingly, by operating the operating element 16b, the square shaft 16 is immersed in the shaft hole 11b against the urging force of the built-in spring 15 in the shaft hole 11b, or protrudes by the urging force of the built-in spring 15, thereby supporting the bearing. It can be inserted into and removed from the square hole 14b of the portion 14.
The angular shaft 16 may be provided only at one end of the cylindrical member 11, and the other end may be a rotatable bearing.

On the other hand, as shown in FIGS. 5 and 8, the support portion 14 that supports the cylindrical member 11 is a rotation that is rotatably supported by the bearing portion 7 a of the upper frame 7 of the window sash 2 of the building opening 1. The rotor 14a is provided with a square hole 14b into which the angular shaft 16 elastically retractable is fitted at the end of the cylindrical member 11, and the angular shaft 16 is fitted into the square hole 14b. A spring 14c is provided for applying an elastic rotational force in the direction of the arrow that tensions the screen 5 to the cylindrical member 11 inserted and held by the rotor 14a.
An openable / closable cover 17 that covers the tubular member 11 is attached to an installation portion of the tubular member 11 in the upper frame 7 of the window sash 2 of the building opening 1.

  The second holding member 20 disposed at the lower end of the screen 5 is detachably attached to the lower frame 8 of the building opening 1 between the pair of left and right vertical frames 6 as clearly shown in FIGS. The horizontal rail 21 is configured to be freely held and to be guided to slide up and down 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 bulging part piece 5a at the left and right side ends of the screen 5 at the groove bottom.

The detachable attachment of the screen 5 to the horizontal rail 21 is provided with a bulging part piece 5b similar to the bulging part piece 5a for engaging the side edge of the screen 5 described above at the lower end of the screen 5, Is attached to the inside of the slit 21b in the mounting groove 21a provided in the longitudinal direction on the upper surface of the horizontal rail 21 by insertion from the end of the slit 21b. In order to make it detachable from the crosspiece 21, for example, the bulging part piece 5b is folded and folded so as to be sandwiched from the lower side, but the screen end holding which has a tendency to expand elastically A known means (for example, see the screen end holding member 22 of Japanese Patent Laid-Open No. 2005-48437) that uses a member and pushes and locks the member into the mounting groove 21a of the horizontal rail 21 may be employed.
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 cylindrical member 11.

  In addition, the detachable holding of the horizontal rail 21 with respect to the lower frame 8 is performed by providing a plurality of protrusions 21 c that elastically protrude on the lower side surface of the horizontal rail 21 and in a groove 8 a formed in the lower frame 8. As shown in FIG. 9, when the horizontal rail 21 is press-fitted, the protrusion 21c is formed so as to be pressed against the inner surface of the groove 8a. However, the configuration is not limited thereto.

As shown in FIG. 10, the screen 5 held by the cylindrical member 11 can be pulled out from the upper part of the building opening 1, and is removed from the concave groove 8a of the lower frame 8 by this pulling out. When the horizontal beam 21 is pulled by the screen 5 and reaches the upper end of the opening 1 of the building, the horizontal beam 21 is arranged in order to enable easy maintenance such as 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 upper frame 7 of the building opening 1.
However, the horizontal rail 21 in contact with the locking portion 7b is taken out by tilting the upper portion of the horizontal rail 21 indoors with the cover 17 opened and the cylindrical member 11 removed from the support portion 14. Thus, it is formed so as to be able to detour from the sliding groove 6b while bypassing the locking portion 7b.

  In the screen device having the above-described configuration, the cylindrical member 11 and the cross rail 21 constituting the first and second holding members 10 and 20 are attached to either side of the upper and lower ends of the screen 5 in the building opening 1. For example, the cylindrical member 11 is disposed at the lower part of the building opening 1 and an openable / closable cover is provided to cover the tubular member 11. It is also possible to adopt a configuration in which the sliding guide 6b of the vertical frame 6 is 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.
