A roll blind 16 attached to a position slightly above the horizontal axis reversal window 14 is provided.

  First, the horizontal axis inversion window 14 will be described. The horizontal axis reversal window 14 includes a sash frame 18 and a window screen 20. The sash frame 18 is a rectangular frame attached to the edge of the opening formed in the outer wall 12 of the building, and is made of metal or wood and holds the window screen 20. The window shoji 20 is opened and closed to switch between a state where the outside of the building communicates with the room and a state where it is blocked. The window shoji 20 is provided with a rectangular glass plate 22 in the center, and a collar 24 is attached so as to surround the upper, lower, left and right sides of the glass plate 22.

  The inversion window 14 outside the horizontal axis opens and closes when the window screen 20 rotates around the rotation axis along the horizontal direction, and the rotation axis also moves with the rotation. When opening the horizontal axis outside inversion window 14, the lower end 20 a of the window shoji 20 is separated from the outer wall 12 of the building and protrudes toward the outdoor side. The horizontal axis inversion window 14 is held by the sash frame 18 via a movable mechanism (not shown) for enabling such an operation. In addition, the shoji 20 for windows is provided with a handle that is held when opening and closing, a locking device for locking, and the like.

  At the lower end portion 20a of the window shoji 20, a fixture 26 for locking a screen bar 42 described later of the roll blind 16 is provided. As shown in FIG. 4, the fixture 26 is made of a metal plate that is long in one direction, is bent at about 90 ° in the middle while avoiding the center in the longitudinal direction, and the portion having a short length to the end is a bent portion. 27, a smooth projection 28 is provided at the tip of the bending portion 27 so as to protrude slightly thick on the bent inner surface. A portion having a long length to the end portion is an attachment portion 30, and the attachment portion 30 is attached so as to overlap the lower end surface 21 of the lower end portion 20 a of the window shoji 20, and two through holes 32 for screws are formed. Has been. As shown in FIG. 5, the attachment 26 is attached so that its longitudinal direction is parallel to the thickness direction of the window shoji 20, and a screw (not shown) is inserted into the through-hole 32 of the attachment portion 30 and fixed to the lower end surface 21. Is done. At this time, the portion of the mounting portion 30 close to the bent portion 27 protrudes to the outside of the window screen 20, and the bent portion 27 is bent in a direction away from the window screen 20 in parallel with the window screen 20 and extends. It will be in the state.

  Next, the roll blind 16 will be described. The roll blind 16 is provided with a screen 34 and a storage box 36. The screen 34 is made of a light-shielding sheet or the like, and is formed in a rectangular shape that can cover the entire glass plate 22. When the screen 34 does not need to cover the reversing window 14 outside the horizontal axis, as shown in FIG. 3, the screen 34 is wound into the storage box 36 while being wound around the winding shaft 40 provided in the storage box 36. Be contained.

  At the lower end of the screen 34, a bar-like screen bar 42 is attached horizontally, which is formed to have a length substantially the same as the width of the screen 34, that is, the length along the left-right direction. The screen bar 42 is a long member having a constant cross-sectional shape, the cross-sectional shape of the screen bar 42 is a hollow circle, and an intermediate plate portion 44 provided in the diametrical direction is integrally provided inside. Slits 46 and 48 that are continuous in the longitudinal direction are provided at positions of the screen bar 42 that are rotated by 90 ° in the circumferential direction with respect to a pair of positions where the middle plate portion 44 is continuous. The slits 46 and 48 are formed along the longitudinal direction of the screen bar 42, and are separated from each other in the diametrical direction. The lower end of the screen 34 is attached to one slit 48. The other slit 46 is a locked portion into which the attachment 26 of the window shoji 20 is inserted and locked, and is formed to have a width in which the protrusion 28 of the attachment 26 can be inserted. A circular cap 50 having a diameter slightly larger than the diameter of the screen bar 42 is attached to both ends of the screen bar 42 in the longitudinal direction.

  The storage box 36 is attached in the vicinity of the upper end of the horizontal axis outside inversion window 14 and holds the winding shaft 40 in a rotatable state. The storage box 36 is a rectangular box formed by a top plate 36a, a front plate 36b, a right plate 36c, and a left plate 36d, and the bottom is opened. In this case, the top plate 36a and the front plate 36b are integrally formed, and the right plate 36c and the left plate 36d are fixed to the top plate 36a with bolts or the like.

  The winding shaft 40 is held inside the storage box 36 in a state of being horizontal and parallel to the outer wall 12. One end of the winding shaft 40 is held by the right plate 36c via a bearing, and the other end is held by the left plate 36d. When the user grasps the screen bar 42 and pulls it downward, the winding shaft 40 rotates and the screen 34 is pulled downward. The winding shaft 40 is provided with a biasing means such as a spring and is always biased in the direction of winding the screen 34. Therefore, when the user releases his / her hand from the screen bar 42 with the screen 34 being pulled out, the take-up shaft 40 is rotated by the spring, and the screen 34 is taken up and stored in the storage box 36. A semicircular cutout 38 is formed in the right plate 36c and the left plate 36d of the storage box 36, and this is a shape in which the caps 50 attached to both ends of the screen bar 42 are half-fitted.

  Next, the operation of the roll blind opening / closing device 10 will be described. When the roll blind opening / closing device 10 does not need to cover the reversing window 14 outside the horizontal axis with the screen 34, the screen 34 is wound around the winding shaft 40 provided in the storage box 36 as shown in FIG. In the storage box 36. The caps 50 attached to both ends of the screen bar 42 are fitted into the cutout portions 38 of the storage box 36 and have a clean appearance. In this state, the window shoji 20 can be opened at an arbitrary angle for aspiration.

  When the screen 34 covers the reversing window 14 outside the horizontal axis, the window screen 20 is opened and the lower end 20a is slid outward, and the window screen 20 passes horizontally and is turned upside down so that the lower end 20a is up. Located in. Then, the screen bar 42 of the roll blind 16 is grasped and pulled down a little to take out the screen 34 from the storage box 36, and the bent portion 27 of the fixture 26 attached to the lower end surface 21 of the lower end portion 20 a of the window shoji 20 is Insert into the slit 46 of the screen bar 42. The slit 46 is positioned on the opposite side of the slit 48 to which the screen 34 is connected, and the fixture 26 is positioned so that the bent portion 27 intersects with the direction in which the screen 34 is pulled back. I can't get out of it. Further, since the projection 28 is formed at the tip of the bent portion 27, the projection 28 comes into contact with the slit 46 and is more difficult to come off.

  With the screen 34 connected to the window screen 20, the window screen 20 is set to a desired angle. The window shoji 20 has a structure that stops at an arbitrary angle. FIG. 1 shows a state in which the window screen 20 is opened most widely, and the window screen 20 is horizontal. The screen 34 follows the movement of the lower end portion 20a of the window shoji 20 and is pulled out and locked to a predetermined length. The lower end portion 20a can be connected to shield sunlight that is inserted into the room from the sash frame 18 of the horizontal axis inversion window 14. And since the window shoji 20 is greatly opened from the sash frame 18, it can fully ventilate.

  FIG. 2 shows a state in which the window screen 20 is closed to the sash frame 18 and the screen 34 is also closed to cover the window screen 20. The window screen 20 is closed by the sash frame 18 and is parallel to the outer wall 12. The screen 34 is also parallel to the window screen 20 and can reliably shield sunlight.

  The window shoji 20 of the inversion window 14 outside the horizontal axis is locked even if it is opened at any other angle, and the angle is changed according to the climate. The screen 34 is pulled out following the movement of the lower end portion 20a of the window shoji 20, is pulled out from the outer wall 12 above the horizontal axis inversion window 14, and is positioned so as to intersect the incident angle of sunlight. .

  According to the roll blind opening / closing device 10 of this embodiment, the screen 34 and the window shoji 20 can be opened and closed simultaneously with a simple operation with a simple structure. Since the screen 34 is provided on the outdoor side of the window screen 20, the screen 34 can reliably block sunlight from entering the room on the outdoor side and suppress an increase in room temperature. Further, in the state where the screen 34 blocks the sunlight, the window shoji 20 can be opened to provide sufficient ventilation. When the window screen 20 is opened, an angle is generated between the screen 34 and the window screen 20, and an effect of taking wind into the room can be expected. It is convenient because the user can extend the hand from the room and attach / detach the screen 34 to / from the window shoji 20. Even if the horizontal axis inversion window 14 is provided on the second floor, the attaching / detaching operation can be performed. When the angle of the window shoji 20 is changed, the screen 34 follows and is pulled out, so that a shielding effect can be surely obtained. Even if wind blows, the screen 34 does not sway, and the vibration caused by the wind does not hit the outer wall 12 to cause damage or noise. In the state where the screen 34 is housed in the housing box 36, maintenance such as wiping the glass plate 22 of the window shoji 20 can be performed without hindrance. Separate parts for holding the screen 34 in the pulled-out state are unnecessary, the number of parts is small, the construction process is small, and the cost can be reduced. Since the number of parts is small, there are few failures and maintenance is easy. Since the roll blind 16 is provided on the outdoor side of the inversion window 14 outside the horizontal axis, it is energy saving that suppresses an increase in room temperature. It can be used for cost-saving homes for energy saving, and the effect of energy saving can be improved.

  The roll blind opening and closing device of the present invention is not limited to the above embodiment, and the structure of each member can be freely changed. The structure, shape, size, and the like of the horizontal axis reversal window can be appropriately changed, and the size of the screen is also changed in accordance with the horizontal axis reversal window. The structure for locking the screen and the shoji for windows may be other than the above embodiment, and the shape of the fixture may be other than the above embodiment, as long as it is securely attached to the screen and can be attached and detached with a simple operation. Further, the screen may be locked to the window shoji at a portion other than the slit of the screen bar, or may be locked to the window shodder by providing a locked portion other than the screen bar. Arbitrary handles and locking devices can be used for the shoji for windows of the horizontal reversal window. The structure of the roll blind storage box can be freely changed. The top plate, the front plate, the right plate, and the left plate may be separated and assembled with screws or the like.
