As shown in FIGS. 1 and 2, the screen device of this embodiment has an awning window, a window, an opening window, a protruding window, etc. in a bay window or a washroom of a detached house or a condominium. The window 2 that can be opened and closed by the opening / closing operation member A by the installed rotary handle is installed inside the window frame of the window in a state close to fitting for the purpose of insect protection, blindfolding, decoration, etc. The bracket 3 that is attached to the opposite side of the opening part where the screen 8 is to be partially opened, that is, the upper part of the building opening frame 1 to fix one end of the screen 8, and is attached to the opening part side end of the screen 8 An operation bar 4 for partially opening the screen 8 and a pair of opposing building opening frames 1 on both sides of the operation bar 4 are provided so that both sides of the screen 8 and the operation bar 4 can slide. And a right and left guide frames 6 and 6 Id.

  As shown in FIG. 2, the screen 8 slidably guided by the guide frames 6 and 6 is configured to be opened upward from the lower part of the building opening frame 1 by opening and closing the operation bar 4. Thus, the fastener halves 8a are attached to both side ends, respectively, and the locking frame 8b of the fastener halves 8a loosely inserted into the guide frame 6 is prevented from escaping from the guide frame 6. A slit 6a is provided. As the fastener half 8a, a known fastener in which the pair of locking heads 8b and 8b are engaged with each other is used because the sliding property of the engaging head 8b is good. Since the pair of locking heads 8b are not engaged with each other, the engagement does not need to be performed reliably.

  As shown clearly in FIGS. 1 and 3 to 5, the pair of guide frames 6, 6 has the maximum opening position of the screen 8 in the guide frame 6 at the end portion on the opening direction side of the screen 8. The screen 8 pressed in the longitudinal direction of the guide frames 6 and 6 with the operation bar 4 is partially cut away by partially cutting away the guide frame 6 at the maximum open position of the screen 8. Is formed out of the guide frames 6, 6, and is led out of the guide frames 6, 6.

More specifically, the screen lead-out portion 10 is formed by partially cutting the indoor side wall 6b of the slit 6a in the guide frame 6 having the slit 6a, and is formed below the cut portion in the indoor side wall 6b. Is formed with an inner opening slope 6c for smoothly leading the screen 8 from the slit 6a. The screen lead-out portion 10 is provided with a cover 10a that covers the outer surface of the screen 8 when the screen 8 is not led out.
The lower portion of the cut portion of the slit 6a on the indoor side wall 6b is not limited to the above-described inner opening slope 6c, and the screen 8 is smoothly led out from the slit 6a when the screen 8 is led out. In this case, an appropriate shape such as a flat shape or a semi-cylindrical shape can be adopted.

  The cover 10a in the screen lead-out part 10 is connected to the bracket 3 so as to be freely opened and closed. Specifically, the cover 10a can be opened and closed to the bracket 3 by a hinge or a flexible flat plate or tape-like member. Alternatively, the cover 10a itself can be integrally formed with the bracket 3 through a thin portion with a flexible synthetic resin. Then, when the operation bar 4 is pushed up, the screen 8 presses and releases the cover 10a at the screen lead-out portion 10 so that the screen 8 does not interfere with the lead-out from the screen lead-out portion 10 to the outside of the guide frame 6.

Therefore, although the self-weight of the cover 10a is configured as an action factor for closing the screen lead-out portion 10, the spring can be biased in the closing direction as necessary. The cover 10a can be supported on the bracket 3 or the like using an appropriate connecting means that can be opened and closed.

  That is, when the lower portion of the screen 8 is opened when the operation bar 4 of the screen 8 is pushed up, the portion of the screen 8 facing the screen lead-out portion 10 pushes up the cover 10a against the weight of the cover 10a. The screen 8 is led out of the guide frame 6 from the screen lead-out unit 10 and the minimum required screen 8 can be opened in accordance with the pressing amount of the operation bar 4, while the push-up of the operation bar 4 on the screen 8 is released. At the time of non-derivation, the screen lead-out part 10 is automatically covered by the cover 10a due to the weight of the cover 10a acting as a factor.

  The screen device for a building opening having the above-described configuration is obtained by cutting a part of the indoor side wall 6b of the slit 6a in the guide frame 6 at the maximum opening position of the screen 8 of the pair of guide frames 6 and 6. Since the portion 10 is formed, when the operation bar 4 is pressed in the opening direction along the guide frame 6, the portion of the screen 8 facing the screen lead-out portion 10 comes off from the guide frame 6 and the guide frame 6. The necessary minimum screen 8 can be opened according to the amount of pressing of the operation bar 4. In addition, since the lower portion of the cut portion on one side wall of the slit 6a is formed on the inclined surface 6c that is open on the inside, the screen 8 can be led out very smoothly from the slit 6a.

  According to the building opening screen device of the present invention described in detail above, the structure for opening the screen 8 is simpler than that of a conventional retractable screen device, and the screen device itself is inserted and killed. Since the screen device can be configured simply and inexpensively, the screen device can be provided at a lower cost and the necessary minimum screen can be easily opened according to the purpose.

It is configured as a thing.

  More specifically, the screen lead-out portion 30 is formed by partially cutting the indoor side wall 26b of the slit 26a in the guide frame 26 having the slit 26a, and the upper and lower portions of the cut portion in the indoor side wall 26b. Are formed with slopes 26c and 26c having an inner opening for smoothly leading the screen 8 from the slit 26a.

  The cover 30a in the screen lead-out portion 30 is connected to the guide frame 26 so as to be opened and closed. However, the cover 30a is connected to the guide frame 26 so as to be opened and closed by a hinge or a flexible plate-like or tape-like member. An appropriate connecting means capable of opening and closing the cover 30a is used, such as connecting to the supporting member 27 separately attached to the frame 26 by a synthetic resin having flexibility through a thin portion so as to be opened and closed. Needless to say, it can be installed.

The building opening screen device having the above-described configuration can be positioned at any intermediate portion of the pair of guide frames 26 and 26 to set the maximum opening position of the screen. For this reason, the position of the screen lead-out portion 30 can be freely set when the position where the screen lead-out portion 30 is formed needs to be considered.
