The upper frame 6, the lower frame 7, and the left and right vertical frames 8, 9 have housing side frame portions 60, 70, 80, 90 located on the exterior material 5 side, and the housing side frame portions 60, 70, 80, 90, The intermediate frame portions 61, 71, 81, and 91 are taken out from the casings 1 </ b> A, 2 </ b> A, 3 </ b> A, and 4 </ b> A (opening portion O) via the 90. The inner portions of the sash frame portions 61A, 71A, 81A, 91A of the window device constitute the sash frame portions 61A, 71A, 81A, 91A. That is, the upper frame 6, the lower frame 7, and the left and right vertical frames 8 and 9 are frame frames 60, 70, 80, 90, and sash frames for attaching window devices from the exterior material 5 of the building body toward the outdoor side. Intermediate frame portions 61, 71, 81, 91 having portions 61A, 71A, 81A, 91A are formed, and a shutter device is attached to the protruding end portions of the upper frame 6, the lower frame 7, and the left and right vertical frames 8, 9. . By providing the frame side frame portions 60, 70, 80, 90 on the frame body, the frame side frame portions 60, 70 are provided between the indoor side of the window device and the frame bodies 1A, 2A, 3A, 4A (opening O). , 80 and 90 are formed as spaces.

The structure of the vertical frames 8 and 9 will be described in more detail. The left and right vertical frames 8 and 9 are frame side frame portions 80 and 90, and intermediate frames formed by being taken out of the building frame by the frame side frame portions 80 and 90. It consists of portions 81 and 91 (inner portions form sash vertical frames 81A and 91A) and tip frame portions 82 and 92 formed at the tips of the intermediate frame portions 81 and 91, respectively. The front end frame portions 82 and 92 are guide rail frames in which the guide rail 14 is integrally formed. Projecting vertical frames 80A and 90A are formed in an opposing manner on the inner side of the frame side frame portions 80 and 90, located on the frame side (inner side) of the sash vertical frames 81A and 91A of the intermediate frame portions 81 and 91. ing. In other words, the protruding vertical frames 80A and 90A constitute the inner portions (opening side portions) of the frame side frame portions 80 and 90. As shown in FIG. 3, the outer prospective surfaces 8A and 9A of the left and right vertical frames 8 and 9 are shifted and protruded toward the side away from the opening O with respect to the frames 3 and 4, while Inner expected surfaces 800 and 900 of the casing-side frame portion 80 (projection frames 80A and 90A) constituting the casing-side portion of the inner expected surface of the vertical frames 8 and 9 are the expected surfaces of the opening O (the surface portions of the frames 3 and 4). It is almost the same. Therefore, the opening width W is not narrowed by the frame side frame portions 80 and 90 of the left and right vertical frames 8 and 9. The frame side frame portion 80 (including the protruding vertical frames 80A and 90A) of the vertical frames 8 and 9 is a hollow frame.

In the illustrated embodiment, each of the upper frame 6, the lower frame 7, and the left and right vertical frames 8, 9 constituting the frame body is configured by assembling a plurality of frame members with screws, but the upper frame 6, the lower frame 7. The left and right vertical frames 8 and 9 may be integrally formed from one member. For example, in the configuration of the vertical frame 8, the sash vertical frame 81A that is a part of the intermediate frame portion 81 of the vertical frame 8 is formed from a separate member, but the intermediate frame portion 81 including the sash vertical frame 81A is formed from one member. You may form integrally. Further, the protruding vertical frame 80A, which is a part of the frame side frame portion 80 of the vertical frame 8, is formed from a separate member, and the hollow portion of the frame side frame portion 80 is partitioned into the internal spaces S1 and S2 by the wall 801. However, the frame side frame portion 80 including the protruding vertical frame 80A may be integrally formed from one member.

The window device includes a window shoji 10 that opens and closes like a louver. The shutter device includes a shutter case 11 that is positioned above the upper frame 6 and protrudes from the exterior member 5, a winding shaft 12 that extends in the width direction of the opening in the shutter case 11, and an upper end that is The shutter curtain 13 is connected to the winding shaft 12, and is wound around the winding shaft 12 by the rotation of the winding shaft 12. The guide rail 14 guides the widthwise end of the shutter curtain 13. And. The guide rail 14 is configured as a part of the front end frame portions 82 and 92 of the vertical frames 8 and 9. The shutter curtain 13 is configured by connecting a plurality of slats 13a vertically.

A pulley 15 is provided at one end of a winding shaft 12 rotatably supported between left and right brackets (only one is indicated by 11A), and the pulley 15 has a circumferential surface around which a tape 16 as an operation member is wound. The winding shaft 12 is rotated via the pulley 15 by pulling the tape 16, and the shutter curtain 13 is wound up to open the opening. A spring spring (not shown) is incorporated in the other end of the winding shaft 12, and the winding of the shutter curtain 13 is facilitated by urging the winding shaft 12 in the direction of winding the shutter curtain 13. I have to. Here, when the shutter curtain is lowered, the weight of the shutter curtain 13 is lowered by overcoming the spring force of the mainspring spring. However, when the shutter curtain 13 is lowered, no force can be transmitted from the tape 16. Therefore, by winding the mainspring spring further than in the natural state, the opening is fully opened, so that the shutter curtain 13 is lowered from the fully opened state as a so-called “lowering” in the fully opened state.

A plurality of protrusions 15a are continuously formed in the circumferential direction on the outer peripheral surface of the pulley 15, and a plurality of locking grooves 15b are formed continuously in the circumferential direction between the protrusions 15a. In the illustrated example, a circumferential surface around which the tape 16 is wound is formed between a pair of opposed flanges 150, and a plurality of locking grooves 15 b are continuously formed in the circumferential direction on the pair of flanges 150. Yes.

A lock member 17 is provided in the shutter case 11 in the vicinity of the pulley 15. The lock member 17 includes a base 18 and a rotation locking body 19 rotatably connected to the base 18. In one embodiment, the base 18 is connected to a bracket 11 </ b> A that forms the side of the shutter case. ing. The rotation shaft 20a between the base end of the rotation locking body 19 and the base 18 is provided with a spring member 20b, and the rotation locking body 19 is urged by the spring member 20b in a direction to rotate toward the pulley. In a natural state where no external force is applied to the rotation locking body 19, the rotation locking body 19 is in a state of jumping up to the pulley side. A locking portion 19a is formed on the distal end side of the rotation locking body 19, and when the rotation locking body 19 rotates to the pulley 15 side, the locking portion 19a is engaged with the locking groove 15b. The pulley 15 is stopped to stop the rotation of the pulley 15. A guide pin 19 b around which the tape 16 drawn from the pulley 15 is wound is formed at the tip of the rotation locking body 19. In the illustrated example, the rotation locking body 19 has two opposing plate pieces 190, a rotation shaft 20 a is provided between the base end portions of the plate pieces 190, and the tip of the plate piece 190. A guide pin 19b is provided between the portions, and a locking portion 19a is provided between the protrusions 190a in the vicinity of the distal end side.

In the shutter case 11, the tape 16 is positioned below the lock member 17 and above the housing-side frame portion 60 of the upper frame 6 (on the exterior material 15 side) and guided obliquely downward from the guide pin 19 b. A guide roller 21 is provided that guides and guides by changing the direction by winding the. The guide roller 21 is supported in a cylindrical portion 11B standing at an opening (not shown) formed in the upper wall 600 of the housing side portion 60 of the upper frame 6, and the tape 16 is supported by the cylindrical portion 11B. It is guided and guided to the guide roller 21 within. Note that the intermediate wall 601 and the lower wall 602 of the housing side portion 60 of the upper frame 6 do not extend up to the upper position of the vertical frames 8 and 9, and the tape 16 guided downward from the opening of the upper wall 600 is vertical. The frame 8 is guided to the opening above the housing side portion 80.

The rotation locking body 19 is attached to the base 18 with the base end on the upper side and the tip side on the lower side. As shown in FIG. 5, in the state in which the rotation locking body 19 is rotated toward the pulley 15, the rotation locking member 17 takes a “<” shape from the base 18 and the rotation locking portion 19. Yes, the locking portion 19a is locked in one of the locking grooves 15b, and the rotation of the pulley 15 is restricted. When the rotation locking body 19 is rotated to the pulley 15 side by the urging force of the spring member 20b, the tape 16 is moved to the pulley 15 side via the guide pin 19b. The tape 16 is led toward the guide roller 21 at an angle by the guide pin 19b in combination with being separated from the outdoor side.

By pulling the tape 16 downward from the state of FIG. 5, as shown in FIG. 6, in the process in which the tape 16 is linearly led out from the pulley 15, via the guide pin 19 b around which the tape 16 is wound. The rotation locking body 19 is rotated in a direction away from the pulley 15, and the locking state of the locking portion 19a and the locking groove 15b is released. By releasing the locking state of the locking portion 19a and the locking groove 15b, the pulley 15 can be rotated and the shutter curtain 13 can be moved up and down.

As shown in FIG. 3, the pulley 15 around which the tape 16 is wound is disposed above the vertical frame 8. More specifically, in plan view, the pulley 15 is located on the outer side (the side away from the opening O, that is, the side close to the outer expected surface 8A) above the vertical frame 8. The tape 16 is guided downward through the guide roller 21 while its direction of orientation is changed by about 90 degrees in plan view (changed from the direction X perpendicular to the opening width to the opening width direction Y as shown in FIG. 3). The frame 8 is introduced into the internal space S1 from the opening above the housing side portion 80, and then introduced into the internal space S2 of the projecting vertical frame 80A through an opening (not shown) formed in the wall 801. From the upper part of the prospective surface 800, it is led out of the protruding vertical frame 80A. That is, the tape 16 is pulled out from the expected surface of the protruding vertical frame 80A to the indoor space (the space inside the window device) outside the opening O.

In FIG. 2, the tape (black coating) 16 </ b> A indicates a tape portion exposed to the outside of the expected surface 800 of the protruding vertical frame 80 </ b> A. The derived tape 16A extends downward along the expectation surface 800, and is introduced into the internal space S2 of the projection vertical frame 80A from the lower portion of the projection surface 800 of the projection vertical frame 80A. Openings 22A and 23A through which the tape 16 is inserted are formed in the upper and lower parts of the prospecting surface 800, and guide rollers 22 and 23 for guiding the tape 16 are provided in the openings 22A and 23A.

As shown in FIG. 8, the tape 16 introduced into the internal space S2 of the protruding vertical frame 80A extends obliquely upward (tape 16B), and is moved to the movable pulley 24 supported in the internal space S2 so as to be movable up and down. It is wound and extended obliquely downward (tape 16C), and its end is fixed to the lower part of the inner wall of the protruding vertical frame 80A. FIG. 8A shows the state of the tape when the shutter is opened. When the shutter is opened, the tape 16 (tape 16A) is pulled downward, but when the movable pulley 24 moves upward, the extra length portion ( The tapes 16B and 16C) are accommodated in the internal space S2 of the protruding vertical frame 80A. FIG. 8B shows the state of the tape when the shutter is closed. When the shutter is closed, the tape is pulled upward, but the moving pulley 24 moves downward to allow the tape 16 to be pulled out. In one embodiment, the movable pulley 24 is supported by the distal end of the rope 25b drawn downward from the case 25a fixed to the upper portion of the wall 801 of the protruding vertical frame 80A, and the proximal end side of the rope 25b is It is biased in the direction of being pulled into the case 25a. Case 25a and rope 25b can be constituted by a commercially available key back chain.

In the window shutter device configured as described above, when the tape 16 is not pulled, the rotation locking body 19 of the lock member 17 is rotated toward the pulley 15 by the biasing force of the spring member 21b, and the rotation locking is performed. The locking portion of the body 19 is locked in the locking groove 15b of the pulley 15, and the rotation of the pulley 15 is restricted. When the tape 16 (tape 16A) is pulled from this state, the portion of the tape 16 wound around the pulley 15, the pin 19b, and the guide roller 21 is tensioned, and is rotated via the pin 19b of the rotation locking body 19. The moving locking body 19 is rotated in a direction away from the pulley 15, the locking state of the locking portion of the rotating locking body 19 and the locking groove 15 b of the pulley 15 is released, and the pulley 15 is freely rotatable. It becomes. Then, by pulling the tape 16 as it is, the winding shaft 12 rotates in the direction of winding the shutter curtain 13 through the pulley 15 to open the opening. When the tape 16 is tensioned to stop the pulling of the tape 16 to such an extent that the rotation locking body 19 is separated from the pulley 15 and maintains the unlocked state, the shutter curtain 13 descends by its own weight and closes the opening. At this time, in order to continue the weight drop of the shutter curtain 13, it is necessary that the tension applied to the tape 16 by its own weight overcomes the force of the spring 20 b.

The locking portion of the rotation locking body 19 is engaged with any one of a plurality of locking grooves 15b formed continuously in the circumferential direction of the pulley 15, whereby the locking portion 19a and the locking groove 15b are engaged. Since the locked state is stopped, the shutter curtain 13 can be stopped at an arbitrary position as well as when the opening is fully closed. Further, since the tape 16 functions only when the locked state is released and does not function to maintain the locked state, the locked state is maintained even if the tape 16 is cut in the locked state. Therefore, even if the tape 16 is cut when the opening is fully opened, the shutter curtain 13 does not fall. Further, in the locked state when the opening is fully closed, the shutter curtain 13 has sufficient strength to lift the shutter curtain 13 from the outdoor side.

The present invention can be used as an operating device for a window shutter.
