The left direction in the figure is defined as the left side of the roll screen 1, and the right direction in the figure is defined as the right side of the roll screen 1. Further, in the example described below, with respect to the front view of the roll screen 1 shown in FIG. 1, the viewing side is the front side (or the indoor side), and the opposite side is the rear side (or the outdoor side). Is a direction perpendicular to the illustrated surface in the front view of FIG.

[First Embodiment]
(overall structure)
First, with reference to FIG. 1, the structure of the roll screen 1 of 1st Embodiment by this invention is demonstrated. FIG. 1 is a front view showing a schematic configuration of a roll screen 1 according to a first embodiment of the present invention.

  A roll screen 1 shown in FIG. 1 has support members 2a and 2b fixed to both ends of a mounting frame 2, and a cylindrical shape between the support members 2a and 2b by a fixed shaft (not shown) extending from the support members 2a and 2b. The winding pipe 3 is rotatably supported. The mounting frame 2 is fixed to the attachment surface by a bracket 6. Each of the support members 2a and 2b is accommodated by the side cover 10 and, as will be described later, improves its design and functionality related to the rotation operation of the light shielding fins 9.

  An operation pulley 8 is provided at the right end of the winding pipe 3, and an endless operation cord 7 hung around the operation pulley 8 is suspended. And it is comprised so that the winding pipe 3 can be rotated by operation of the operation cord 7, and the surface of the operation pulley 8 on which the operation cord 7 is wound has a highly frictional surface shape. The operation cord 7 may be formed of a ball chain, and the surface of the operation pulley 8 around which the ball chain is hung may be configured to have irregularities having a shape suitable for the ball portion of the ball chain.

  The take-up pipe 3 is attached to one end of the screen 4 and is supported so as to be able to take up. The other end of the screen 4 is attached to a weight bar 5 that functions as a weight member. Accordingly, the screen 4 is stretched based on the weight of the weight bar 5.

  When the operation cord 7 is operated to rotate the winding pipe 3 in the screen winding direction, the weight bar 5 is raised, and when the winding pipe 3 is rotated in the screen unwinding direction, the weight bar 5 is lowered.

  Further, in the take-up pipe 3, a spring motor for reducing the operating force when the screen 4 is wound is housed on the left end side, and a stopper or the like for preventing the weight of the screen 4 from dropping is housed on the right end side ( Not shown).

  Therefore, in the roll screen 1 according to the present invention, the light shielding fin 9 is attached to the back side of the mounting frame 2 with a structure that is not likely to be damaged by the collision of the weight bar 5, and between the winding pipe 3 and the mounting frame 2. The light leakage from the gap caused by the above is effectively shielded, and the light shielding fin 9 of one embodiment will be described in detail below.

(Shading fin)
FIG. 2 is an exploded perspective view showing a schematic configuration around the light shielding fins 9 in the roll screen 1 according to the first embodiment of the present invention. Referring to FIG. 2, the light shielding fin 9 has a substantially L-shaped cross-sectional shape as a whole and is pivotally supported on the back side of the mounting frame 2. The left-right direction width Ls of the light shielding fin 9 is slightly shorter than the left-right direction width Lf of the mounting frame 2. The light shielding fins 9 have high light shielding properties. For example, when the light shielding fins 9 are made of synthetic resin, the lateral width Ls is slightly shorter than the lateral width Lf of the mounting frame 2. Even if the width in the left-right direction changes, the rotation is smoothly supported.

  A bearing portion 20 having a substantially C-shaped cross section extending in the longitudinal direction is formed below the rear surface of the mounting frame 2. The shaft portion 91 of the light shielding fin 9 is engaged with the bearing portion 20, whereby the light shielding fin 9 is rotatably supported on the back side of the mounting frame 2. Support members 2 a and 2 b are attached to both ends of the mounting frame 2 in the longitudinal direction.

  The support members 2 a and 2 b are provided with a notch 23 having a size that substantially matches the substantially C-shaped cross-sectional shape of the bearing portion 20 of the mounting frame 2. This notch 23 is provided so that the shaft portion 91 of the light shielding fin 9 can be slid from the left and right direction and inserted into the bearing portion 20 to be supported after the mounting frame 2 is fixed by the support members 2a and 2b. ing. Then, the light shielding fins 9 are slid to be removable, and other than this slide are not removable, so that the light shielding fins 9 are not detached from the mounting frame 2 due to the collision of the weight bar 5. Regarding the removal of the light shielding fins 9, with respect to the position of the notch 23 in the support member 2a having the notch 23 on the outdoor side (however, the notch 23 may be provided on the outdoor side of the support member 2b), The light shielding fins 9 can be flipped up and removed by sliding the light shielding fins 9 in the left-right width direction when a certain position is reached.

  Further, a screw hole 21 for fixing the mounting frame 2 using mounting screws and a fixed shaft (not shown) for rotatably supporting the winding pipe 3 are fixed to the support members 2a and 2b. Screw holes 22 are provided at a plurality of locations. Although the side cover 10 is attached from the viewpoint of the design property, the side cover 10 also has an effect of improving the functionality related to the rotation operation of the light shielding fins 9.

  That is, as will be described in detail later, the side cover 10 has a height so as to restrict both end positions of the light shielding fin 9 in the left-right direction within the rotation range of the light shielding fin 9 so that the light shielding fin 9 can be smoothly rotated. A wall portion 10a having a thickness is formed. The height of the wall 10a is sufficiently high to accommodate the thickness of the support members 2a and 2b. The side cover 10 is made of synthetic resin and can be attached with a narrow pressure following the outer shape of the support members 2a and 2b formed of a metal material. An inwardly projecting claw portion 10b is formed. That is, with respect to the rotation operation of the light shielding fin 9, the wall portion 10a has a height so that the claw portion 10b and the notch 23 do not hinder the rotation operation. Although details will be described later with reference to FIG. 7, the wall portion 10 a of the side cover 10 abuts against the support members 2 a and 2 b before the light shielding fin 9 abuts and restricts the light shielding fin 9 to be rotatable. In other words, by restricting both end portions of the light shielding fin 9 in the left-right direction, the design property is secured, and the adverse effect of rotation can be prevented while enhancing the light leakage effect. In this example, the left-right direction width Ls of the light-shielding fin 9 is configured to be slightly shorter than the left-right direction width Lf of the mounting frame 2, and the light-shielding fin 9 is regulated to be rotatable by the wall portion 10a of the side cover 10. Although an example of the configuration is shown, the support members 2 a and 2 b and the side cover 10 may be avoided depending on the shape of the light shielding fin 9.

  FIG. 3 is a side view showing the configuration of the light shielding fins 9 in the roll screen according to the first embodiment of the present invention. In FIG. 3, the side cross-sectional shape of the mounting frame 2 is also shown by broken lines in order to enhance the understanding of the invention. A bearing portion 20 having a substantially C-shaped cross section extending in the longitudinal direction is formed below the rear surface of the mounting frame 2. More specifically, the bearing portion 20 forms a bent shaft 20f at the tip of a rotation restricting piece 20a extending upward from the bottom portion of the mounting frame 2 so that the shaft portion 91 of the light shielding fin 9 can be supported. The rotation restricting piece 20 a has a function of restricting the downward rotation of the light shielding fin 9. In addition, a rotation restricting piece 20 b that restricts the upward rotation of the light shielding fin 9 is formed above the bearing portion 20 on the back surface of the mounting frame 2. In the example shown in the figure, the rotation restricting piece 20a is formed in a substantially C shape protruding rearward from the back of the main body of the mounting frame 2, and the rotation restricting piece 20b is formed in a substantially plate shape protruding rearward. In the state where the shaft portion 91 of the light shielding fin 9 is pivotally supported by the bearing portion 20, the rotation of the light shielding fin 9 in the vertical direction is restricted, and no matter how the light shielding fin 9 is rotated, the rearward direction. The outer bearing portion 20 is prevented from being detached.

  The light shielding fin 9 has a substantially L-shaped cross-sectional shape as a whole, and is formed of a single member having a double curved surface shape so as to alleviate a collision force caused by interference with the weight bar 5. The light shielding fin 9 mainly includes a shaft portion 91, a shielding portion 93, a fabric contact portion 94, and an interference mitigation portion 95.

  The shaft portion 91 is a portion that is pivotally supported by the bearing portion 20. The shielding part 93 is a part that prevents light leakage caused by a gap between the mounting frame 2 and the winding pipe 3. The fabric contact portion 94 is a portion that is brought into contact with or close to the screen 4 that is wound or unwound by the winding pipe 3. The interference mitigating portion 95 is a portion that mitigates interference when the weight bar 5 rises and collides with the winding of the screen 4.

  The light shielding fins 9 are balanced in weight so as to increase the amount of proximity between the fabric contact portion 94 and the screen 4 in order to prevent light leakage when the screen 4 is fully closed.

  The shaft portion 91 of the light shielding fin 9 is pivotally supported by the bearing portion 20 and has a substantially C-shaped cross section as a whole. The front end of the shaft portion 91 is formed in a substantially T-shaped cross section, and is engaged with the bearing portion 20 with a spatial margin so that the light shielding fins 9 are not easily detached from the bearing portion 20 and the light shielding is performed. The degree of freedom of rotation of the fin 9 is increased. On the other hand, when the shaft portion 91 of the light shielding fin 9 is pivotally supported by the bearing portion 20 in such a manner that the degree of freedom of rotation is increased in this manner, an unpleasant interference sound due to the rotational interference between the light shielding fin 9 and the rotation regulating piece 20b ( Therefore, it is preferable that the shaft portion 91 is formed with a curved portion 92 having a thickness in the rotation range by changing the thickness of the shaft portion 91 as shown in FIG. is there. As described above, the shaft portion 91 of the light shielding fin 9 can reduce a sound caused by rattling during rotation while maintaining a sufficient space for reducing the rotation load.

  The fabric contact portion 94 is a part that is brought into contact with or close to the screen 4 to be wound or rewinded by the winding pipe 3. When the screen 4 is wound around the winding pipe 3 as shown in FIG. The light shielding fins 9 can be rotated following the thickness of 4. The cloth contact portion 94 has a rounded cross-sectional shape, which makes the light shielding fins 9 rotate smoothly. However, as shown in FIG. 4B, when the weight bar 5 is lifted, the weight bar 5 is not in contact with the screen 4 in a state where the weight bar 5 is in contact with the light shielding fin 9.

  The shielding portion 93 is a portion between the shaft portion 91 and the fabric contact portion 94 and is formed with a length that prevents light leakage generated from a gap between the mounting frame 2 and the winding pipe 3. Further, the shielding part 93 is formed in a curved cross-sectional shape so as to be generally convex upward. By forming the shielding portion 93 in this way, the height associated with the rotation of the light shielding fin 9 required when the weight bar 5 is positioned at the uppermost position is further reduced (as shown in FIG. 4B). The distance d2) can prevent damage due to the jumping up of the light shielding fin 9, and can further reduce the required distance on the back side of the mounting frame 2 required for the jumping up of the light shielding fin 9 (shown in FIG. 4B). Distance d1). The uppermost position of the weight bar 5 shown in this example is a position where the weight bar 5 comes into contact with the mounting frame 2.

  For example, like the light shielding fin 109 of Comparative Example 1 shown in FIG. 5A, the weight bar 5 is positioned at the uppermost position when the shielding portion 93 is formed in a curved cross-sectional shape so as to be convex downward. The height required to rotate the light shielding fin 109 is increased (distance d2 ′ shown in FIG. 5A), and the tip of the light shielding fin 109 is caused to rise due to the splashing of the light shielding fin 109. There is a risk of crashing and damage. Further, when the shielding portion 93 is formed in a substantially linear cross-sectional shape as in the light shielding fin 209 of the comparative example 2 shown in FIG. 5B, it is necessary on the back side of the mounting frame 2 required for the light shielding fin 209 to jump up. The distance is longer than that of the light shielding fin 9 according to the present invention, and the installation efficiency is deteriorated (distance d1 ′ shown in FIG. 5B).

  Further, as shown in FIGS. 3 and 4, the shielding portion 93 is preferably provided with an upper protrusion 97 that restricts the upward rotation of the light shielding fin 9 in the vicinity of the shaft portion 91. The upper protrusion 97 is formed so as to be able to come into contact with the rotation restricting piece 20 b of the mounting frame 2, thereby restricting the upward rotation of the light shielding fin 9. In addition, it is preferable that the shielding portion 93 is provided with a lower protrusion 98 that restricts the downward rotation of the shielding fin 9 in the vicinity of the shaft portion 91. Although it is not necessary to provide the lower protrusion 98, it is effective when the contact pressure with the screen 4 is relaxed (or is not in contact) and damage to the screen 4 due to friction when the screen 4 is raised and lowered is suppressed. . In the state where the shaft portion 91 of the light shielding fin 9 is supported by the bearing portion 20, the upper projection 97 and the lower projection 98 restrict the rotation of the light shielding fin 9 in the vertical direction. No matter how the fins 9 are rotated, they are not detached from the bearing portion 20 in the rear direction.

  The interference mitigation part 95 is formed in a wavy curved surface shape (curved cross-sectional shape) so as to mitigate interference when the weight bar 5 rises and collides with the winding of the screen 4. In particular, it is preferable that the distal end portion 96 of the interference mitigating portion 95 has a curved shape that escapes upward in order to prevent insertion of the weight bar 5 into the opening 51 as shown in FIG.

  As shown in FIG. 4, the light shielding fin 9 configured in this way has a structure that is not likely to be damaged by the collision of the weight bar 5, and is formed from a gap generated between the winding pipe 3 and the mounting frame 2. Light leakage can be effectively shielded. In addition, as described above, since it has a structure that reduces the contact sound related to the collision between the light shielding fin 9 and the weight bar 5, it is possible to reduce operational discomfort.

  Further, the design of the side cover 10 and the functionality related to the rotation operation of the light shielding fins 9 are improved. As shown in FIG. 6A, the support member 2b (2a) has a screw hole 21 for fixing the mounting frame 2 using mounting screws and a fixing for rotatably supporting the winding pipe 3. Screw holes 22 for fixing a shaft (not shown) are provided at a plurality of locations. In the state where the light shielding fin 9 is pivotally supported by the bearing portion 20 of the mounting frame 2, the notch 23 is also visible as shown in FIG. For this reason, as shown in FIG.6 (c), the design property can be improved by attaching the side cover 10 to the supporting member 2b (2a).

  Further, the side cover 10 includes a light shielding fin 9 within a rotation range of the light shielding fin 9 as shown in a partial rear view and a side view of the side cover 10 according to the present invention shown in FIGS. A wall portion 10a having a height (a hatched portion shown in the figure) is formed so as to restrict both the left and right end positions. And the nail | claw part 10b which protrudes inward which can hold | maintain the supporting members 2a and 2b is formed in the wall part 10a.

  On the other hand, when the wall 10a is not formed in this way and the cover side wall is short, as shown in the partial rear view and side view of the side cover 100 of the comparative example of FIGS. 7 (c) and 7 (d), As the light-shielding fin 9 rotates, the light-shielding fin 9 rides on the claw portion 10b or the notch 23, and the light-shielding fin 9 cannot be completely closed, which may cause light-shielding failure. Therefore, in the present invention, the left-right width Ls of the light shielding fin 9 is configured to be slightly shorter than the left-right width Lf of the mounting frame 2 (see FIG. 2), and the claw portion 10b and the notch 23 rotate. The wall 10a has a height so as not to impede the light, and both the left and right ends of the light shielding fins 9 are slid by the wall 10a of the side cover 10, thereby improving the light leakage effect and rotating trouble. Can be prevented.

[Second Embodiment]
Next, with reference to FIG.8 and FIG.9, the structure of the roll screen 1a of 2nd Embodiment by this invention is demonstrated. FIG. 8 is a front view showing a schematic configuration of a roll screen 1a according to the second embodiment of the present invention. FIG. 9 is a partial side perspective view showing a schematic configuration of the roll screen 1a of the second embodiment according to the present invention. In addition, the same reference number is attached | subjected to the component similar to 1st Embodiment.

  The roll screen 1a shown in FIG. 8 is configured to open and close the screen 4 by the pull grip 12 provided on the weight bar 5a, instead of providing the operation cord 7 and the operation pulley 8, as compared with the first embodiment. It is an example and the further description of the component similar to 1st Embodiment is abbreviate | omitted.

  The take-up pipe 3 is attached to one end of the screen 4 and is supported so as to be able to take up. The other end of the screen 4 is attached to a weight bar 5a with a pull support that functions as a weight member. Accordingly, the screen 4 is stretched based on the weight of the weight bar 5a.

  Further, a winding mechanism (for example, a spring motor) that automatically winds up the screen 4 and a stopper device that prevents the weight of the screen 4 from falling down are accommodated in the winding pipe 3 (not shown). Therefore, when the stopper device is not operating, the winding pipe 3 is operated to rotate in the screen winding direction by the winding mechanism.

  A pull grip 12 that can be pulled downward is attached to the lower end of the substantially central portion of the weight bar 5a. As shown in FIG. 9, the pull grip 12 is suspended from a part of the weight bar 5a via the pull cord 12a.

  That is, when the pull grip 12 is pulled downward, the winding pipe 3 is rotated in the screen rewinding direction, the weight bar 5a is lowered, and when the pull grip 12 is released at an arbitrary position, the screen 4 is pulled out by the stopper device. Stop in state. When the pull grip 12 is pulled slightly downward from this state, the lock by the stopper device is released, the winding pipe 3 rotates in the screen winding direction, and the weight bar 5a rises. In this way, the amount of light collected into the room can be adjusted by winding or rewinding the screen with the winding pipe 3.

  As described above, the light shielding fins 9 described in the first embodiment can be used in common for the roll screen 1a using the pull grip 12, and the same operation and effect as in the first embodiment can be obtained. it can. The roll screen 1a according to the second embodiment is configured to open and close the screen 4 with the roll screen 1 according to the first embodiment provided with the operation cord 7 and the operation pulley 8 and the pull grip 12 provided on the weight bar 5a. Since the light shielding fins 9 can be shared, the component cost can be reduced.

[Third Embodiment]
Next, with reference to FIG. 10, the structure of the roll screen 1b of 3rd Embodiment by this invention is demonstrated. FIG. 10 is a partial side perspective view showing a schematic configuration of a roll screen 1b according to a third embodiment of the present invention. In addition, the same reference number is attached | subjected to the component similar to 1st and 2nd embodiment.

  As a modification of the second embodiment, a roll screen 1b shown in FIG. 10 includes a shape of a bearing portion 20 provided below the back surface of the mounting frame 2, and a shaft portion 91 in a light shielding fin 9a that engages with the bearing portion 20. This is an example in which the shape is inverted up and down as compared with that shown in FIG. 9, and further description of the same components as those in the first and second embodiments is omitted. The bearing portion 20 of this example has a bent shaft 20f formed at the tip of a rotation restricting piece 20b that is bent downward from one side portion of the mounting frame 2, and the shaft portion of the light shielding fin 9a is formed by the bent shaft 20f. 91 can be pivotally supported. Further, the rotation restricting piece 20a shown in FIG. 10 is formed so as to extend upward from the bottom of the frame 2, and functions to restrict the downward rotation of the light shielding fins 9a and to receive contact with the weight bar 5. Have. Even when formed in this way, the light-shielding fin 9 is attached to the back side of the mounting frame 2 with a structure that is not damaged by the collision of the weight bar 5a, and a gap generated between the winding pipe 3 and the mounting frame 2 It is possible to effectively shield light leakage from the light.

  Therefore, as a modification of the first embodiment in which the operation cord 7 and the operation pulley 8 are provided, the shape of the bearing portion 20 provided below the back surface of the mounting frame 2 and the light shielding fins 9a that engage with the bearing portion 20 are provided. The shape of the shaft portion 91 can be configured to be inverted up and down as compared with that shown in FIG.

  The shading fin 9 (or 9a) can be attached to the back side of the mounting frame 2 and pivotally supported in various forms. For example, the bearing portion 20 of the mounting frame 2 is configured such that the side cross-sectional shape is indicated by a broken line in FIG. 11A, and the shaft portion 91 of the light shielding fin 9 having the same structure as that shown in FIG. Can be made. More specifically, the bearing portion 20 has a round shaft 20e formed at the tip of a rotation restricting piece 20a extending upward from the bottom of the mounting frame 2, and the shaft portion 91 of the light shielding fin 9 is formed by the round shaft 20e. Can be pivoted.

  Alternatively, the bearing portion 20 of the mounting frame 2 is configured so as to illustrate the side sectional shape with a broken line in FIG. 11B, and the shaft portion 91 of the light shielding fin 9a having the same structure as that shown in FIG. Can be supported. More specifically, the bearing portion 20 forms a bending shaft 20f at the tip of a rotation restricting piece 20b that is bent and extended downward from one side portion of the mounting frame 2, and the light shielding fin 9 is formed by the bending shaft 20f. The shaft portion 91 can be pivotally supported. In the example shown in FIG. 11B, the rotation restricting piece 20a is not formed as compared with the example shown in FIG. In this case, contact with the weight bar 5 is received by the light shielding fin 9a. However, since the contact with the weight bar 5 is received in the vicinity of the shaft portion 91 of the light shielding fin 9a, the light shielding fin 9a due to collision of the weight bar 5 is performed. No damage will occur. In addition, since the rotation restricting piece 20a is not formed, the required distance on the back side of the light shielding fin 9a on the back surface of the main body of the mounting frame 2 can be made shorter than in the example shown in FIG.

  Alternatively, the bearing portion 20 of the mounting frame 2 is configured so as to illustrate the side sectional shape with a broken line in FIG. 12A, and the shaft portion 91 of the light shielding fin 9 having the same structure as that shown in FIG. Can be supported. More specifically, the bearing portion 20 forms a bending shaft 20f at the tip of a rotation restricting piece 20a extending upward from the bottom of the mounting frame 2, and the shaft portion 91 of the light shielding fin 9 is formed by the bending shaft 20f. Can be pivoted. In addition, it can also be set as the round shaft 20e shown to Fig.11 (a) instead of this bending shaft 20f. Further, above the bearing portion 20 on the back surface of the mounting frame 2, a rotation restricting piece 20 b that restricts the upward rotation of the light shielding fins 9 and suppresses rattling due to the rotation of the light shielding fins 9 is substantially C. It is formed in a cross-sectional shape. Therefore, as shown in the drawing, the bearing frame 20 can be formed by opening the back side of the mounting frame 2, and the shaft portion 91 of the light shielding fin 9 having the same structure as that shown in FIG. 3 can be pivotally supported.

  Alternatively, the bearing portion 20 of the mounting frame 2 is configured so as to illustrate the side sectional shape with a broken line in FIG. 12B, and the shaft portion 91 of the light shielding fin 9 having the same structure as that shown in FIG. Can be supported. More specifically, the bearing portion 20 opens the bottom of the mounting frame 2 and forms a bending shaft 20f at the tip of a protruding piece extending upward from the indoor bottom of the mounting frame 2. The bending shaft 20f The shaft portion 91 of the light shielding fin 9 can be pivotally supported. In addition, it can also be set as the round shaft 20e shown to Fig.11 (a) instead of this bending shaft 20f. Further, above the bearing portion 20, a rotation restricting piece 20 b that extends upward from the outdoor bottom of the mounting frame 2, restricts the rotation range of the light shielding fin 9, and suppresses rattling caused by this rotation, is approximately C. It is formed in a cross-sectional shape. Therefore, as shown in the drawing, the bottom surface side of the mounting frame 2 is opened to form the bearing portion 20, and the shaft portion 91 of the light shielding fin 9 having the same structure as that shown in FIG. 3 can be pivotally supported. In this example, particularly, when the light shielding fin 9 is rotated from the state indicated by the broken line to the state indicated by the solid line, the light shielding fin 9 receives contact with the weight bar 5, but the shielding portion 93 of the light shielding fin 9 is provided. Is in contact with a relatively wide range of the bottom surface of the mounting frame 2 and is in contact with the weight bar 5, so that the light shielding fins 9a are not damaged by the collision of the weight bar 5. Further, compared to the case where the light shielding fins 9 (or 9a) are pivotally supported on the rear surface of the mounting frame 2 as shown in FIG. The required distance can be made shorter.

[Fourth Embodiment]
Next, with reference to FIG. 13, the structure of the roll screen 1c of 4th Embodiment by this invention is demonstrated. FIG. 13 is a partial side perspective view showing a schematic configuration of a roll screen 1c according to a fourth embodiment of the present invention. In addition, the same reference number is attached | subjected to the component similar to each embodiment mentioned above.

  The roll screen 1c shown in FIG. 13 is configured to form a bearing portion 20 on the front side portion of the mounting frame 2 and to support the shaft portion 91 of the light shielding fin 9b on the indoor bottom side of the mounting frame 2. The light shielding fin 9b is mainly composed of a shaft portion 91, a shielding portion 93, a fabric contact portion 94, and an interference mitigation portion 95, similar to the above-described light shielding fin 9 (or 9a), and has substantially the same structure and function. The light shielding fins 9b as a whole are formed in a curved surface shape. As shown in FIG. 13, the distal end portion 96 of the interference mitigating portion 95 has a curved shape that escapes upward in order to prevent insertion of the weight bar 5 into the opening 51. However, the light shielding fin 9b is in contact with the screen 4 that is wound or rewinded by the winding pipe 3 in the shielding portion 93 as compared with the light shielding fin 9 shown in FIG. 4 or the light shielding fin 9a shown in FIG. This is particularly different in that the shielding portion 93 is formed in a flat shape so as to allow the above.

  The bearing portion 20 of this example has a bent shaft 20f formed at the tip that is bent downward from the front side portion of the mounting frame 2 and the shaft portion 91 of the light shielding fin 9b is pivotally supported by the bent shaft 20f. Can do. In this example, in particular, when the light shielding fin 9b is rotated from the state indicated by the broken line to the state indicated by the solid line, the light shielding fin 9b receives contact with the weight bar 5. Since the fabric contact portion 94 abuts against the bottom end of the mounting frame 2 and receives contact with the weight bar 5 in the vicinity of the fabric contact portion 94 of the light shielding fin 9b, the light shielding fin 9b is damaged by the collision of the weight bar 5. Does not occur. Further, in this example, as is clear from FIG. 13, compared to the example of the light shielding fin 9 (or 9a) shown in FIG. 4 and FIG. The distance can be shortened.

[Fifth Embodiment]
Next, with reference to FIG. 14, the structure of the roll screen 1d of 5th Embodiment by this invention is demonstrated. FIG. 14 is a partial side perspective view showing a schematic configuration of the roll screen 1d according to the fifth embodiment of the present invention. In addition, the same reference number is attached | subjected to the component similar to each embodiment mentioned above.

  The roll screen 1d shown in FIG. 14 forms a cylindrical bearing portion 20 at the bottom of the mounting frame 2, covers the round shaft portion 91 of the light shielding fin 9c at the indoor bottom of the mounting frame 2, and A round shaft 91 is protruded from both left and right ends of 9c and is supported by a shaft support 24 provided on the support members 2a and 2b. The light shielding fin 9c is mainly composed of a shaft portion 91, a shielding portion 93, a fabric contact portion 94, and an interference mitigation portion 95, similar to the above-described light shielding fin 9 (or 9a), and has substantially the same structure and function. The light shielding fins 9b as a whole are formed in a curved surface shape. As shown in FIG. 13, the distal end portion 96 of the interference mitigating portion 95 has a curved shape that escapes upward in order to prevent insertion of the weight bar 5 into the opening 51. However, the light shielding fin 9c has a round shaft portion 91 as compared with the light shielding fin 9 shown in FIG. 4 and the light shielding fin 9a shown in FIG. Thus, the shielding portion 93 is particularly different in that it is configured to have a flat shape so as to allow contact with the screen 4 to be wound or rewound.

  The bearing portion 20 of this example is formed in a cylindrical shape so as to cover the round shaft portion 91 of the light shielding fin 9c, and the left and right ends of the round shaft portion 91 of the light shielding fin 9c are round shaft shapes. The shaft portion 91 protrudes so as to be supported by the shaft support portion 24 provided on the support members 2a and 2b (not shown). Thereby, the light shielding fin 9c can be supported by the support members 2a and 2b so as to be rotatable. In this example, in particular, when the light shielding fin 9c is rotated from the state indicated by the broken line to the state indicated by the solid line, the light shielding fin 9c receives contact with the weight bar 5. Since the shielding portion 93 abuts on a relatively wide range of the bottom surface of the mounting frame 2 and is abutted against the weight bar 5, the light shielding fin 9 c is not damaged by the collision of the weight bar 5. Further, in this example, as is clear from FIG. 14, compared to the example of the light shielding fin 9 (or 9 a) shown in FIGS. 4 and 10, the rear surface side of the light shielding fin 9 c on the rear surface of the main body of the mounting frame 2 is necessary. The distance can be shortened.

  As described above, in the roll screens of the first to fifth embodiments, the light shielding fins 9 (or 9a to 9c) are on the rear side of the mounting frame 2 with a structure that is not likely to be damaged by the collision of the weight bar 5 (or 5a). Alternatively, it is attached to the bottom surface side, and light leakage from the gap generated between the winding pipe 3 and the mounting frame 2 can be effectively shielded.

[Sixth Embodiment]
Next, with reference to FIG. 15, the structure of the roll screen 1e of 6th Embodiment by this invention is demonstrated. FIG. 15 is a partial side perspective view showing a schematic configuration of a roll screen 1e according to a sixth embodiment of the present invention. Note that the same reference numerals are assigned to the same components as those in the first to fifth embodiments.

  The roll screen 1e of the sixth embodiment differs from that described in the first to fifth embodiments in the shape of the bearing portion 20 provided below the back surface of the mounting frame 2 and the light shielding that engages with the bearing portion 20. Although the structure of the fin 9d is different, other components are the same, and further description thereof is omitted.

  In the roll screen 1e of the sixth embodiment, the shape of the bearing portion 20 provided below the back surface of the mounting frame 2 is such that the rotation restricting piece 20a that restricts the downward rotation of the light shielding fin 9d and the light shielding fin 9d. It is comprised so that it may have the rotation control piece 20b which controls rotation to upper direction, and the recessed part 20c which gave the dent in the substantially semicircle shape.

  The light shielding fins 9d have a connecting multi-member configuration that can be bent so as to reduce the collision force caused by the interference with the weight bar 5, and mainly include the shaft portion 91a, the shielding portion 93a, the fabric contact portion 94a, and the interference. It consists of a relaxation part 95a. The light shielding fins 9b are connected to each other at the position of the fabric contact portion 94a so that the members constituting the shaft portion 91a and the shielding portion 93a and the members constituting the interference mitigation portion 95a can be bent.

  The shaft portion 91 a is a portion that is pivotally supported by the bearing portion 20. The shielding part 93 a is a part that prevents light leakage caused by a gap between the mounting frame 2 and the winding pipe 3. The cloth contact portion 94 a is a connecting portion that can be bent, and a portion that is brought into contact with or close to the screen 4 that is wound or rewinded by the winding pipe 3. The interference mitigating portion 95a is a portion that mitigates interference when the weight bar 5 rises and collides with the winding of the screen 4.

  The light shielding fins 9d are balanced in weight so as to increase the proximity amount between the fabric contact portion 94a and the screen 4 in order to prevent light leakage when the screen 4 is fully closed.

  The shaft portion 91a of the light shielding fin 9d is pivotally supported by the bearing portion 20, and has a substantially circular cross-sectional shape as a whole. The shaft portion 91a is engaged with the bearing portion 20 in such a manner that the shaft portion 91a does not rattle, thereby making it difficult for the light shielding fin 9d to be detached from the bearing portion 20 and increasing the degree of freedom of rotation of the light shielding fin 9d. By engaging in such a manner that no rattling occurs, unpleasant interference sound (contact sound) due to rotational interference between the shielding portion 93a of the light shielding fin 9d and the rotation restricting piece 20b is prevented.

  The fabric contact portion 94a is connected to the screen 4 that flexibly connects the member that constitutes the shaft portion 91a and the shielding portion 93a and the member that constitutes the interference mitigation portion 95a, and winds or rewinds by the take-up pipe 3. The light shielding fin 9d can be rotated in accordance with the winding thickness of the screen 4, which is a part to be brought into contact with or close to. The fabric contact portion 94a is capable of relative rotation between the end portion of the substantially C-shaped cross section of the member constituting the shaft portion 91a and the shielding portion 93a and the end portion of the substantially circular cross section of the member constituting the interference mitigating portion 95a. It is linked to. Thereby, the rotation of the light shielding fin 9d is made smooth. In addition, the connection form by this fabric contact part 94a is arbitrary as long as the member which comprises the axial part 91a and the shielding part 93a and the member which comprises the interference mitigation part 95a can be rotated relatively. You may connect with a tape etc. In the example of the present embodiment, it is possible to bend with a two-member configuration as described above, but three or more members may be used.

  The shielding part 93a is a part between the shaft part 91a and the fabric contact part 94a, and is formed with a length that prevents light leakage caused by a gap between the attachment frame 2 and the winding pipe 3. Further, the shielding part 93a is formed in a curved cross-sectional shape so as to be convex upward substantially bent by the curved part 92a. By forming the shielding portion 93a in this way, the height associated with the rotation of the light shielding fin 9d, which is required when the weight bar 5 is positioned at the uppermost position, is further reduced, and the light shielding fin 9d is bounced up. This is the same as in the first embodiment in that the necessary distance on the back side of the mounting frame 2 required for jumping up the light-shielding fins 9d can be shortened while preventing the resulting damage.

  Moreover, since the shielding part 93a has the shape bent by the curved part 92a, as shown in FIG. 15, in the area | region between the curved part 92a and the axial part 91a, the rotation control piece of the attachment frame 2 is provided. 20b can be contacted, and thereby, the upward rotation of the light shielding fin 9b can be restricted. In a state where the shaft portion 91a of the light shielding fin 9d is supported by the bearing portion 20, no matter how the light shielding fin 9d is rotated, the shaft portion 91a is not detached from the bearing portion 20. In addition, the attachment method of the axial part 91a of the light shielding fin 9d with respect to the bearing part 20 of the attachment frame 2 is the same as that of 1st Embodiment.

  The interference mitigating portion 95a is bent at the position of the fabric contact portion 94a, and mitigates interference when the weight bar 5 rises and collides with the winding of the screen 4. In particular, as shown in FIG. 15, it is preferable that the distal end portion 96a of the interference mitigating portion 95a has a rounded curved surface shape to prevent insertion of the weight bar 5 into the opening 51.

  The light shielding fin 9d configured in this way has a structure that is not likely to be damaged by the collision of the weight bar 5, and effectively shields light leakage from the gap between the winding pipe 3 and the mounting frame 2. can do. In addition, as described above, since it has a structure that reduces the contact sound related to the collision between the light shielding fin 9d and the weight bar 5, it is possible to reduce operational discomfort.

  And it is needless to say that the light shielding fin 9d shown in FIG. 15 can be applied to a roll screen using the pull grip 12 as described in the second embodiment.

  The present invention has been described above with reference to specific embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the technical concept thereof. For example, in each embodiment, the example in which the light shielding fin according to the present invention is applied to a roll screen that hangs the screen 4 from the outdoor side of the winding pipe 3 has been described. The screen 4 can also be configured to be used as a common member for a roll screen that hangs down from the indoor side of the winding pipe 3.

  Moreover, in the roll screen of each embodiment, there is an example in which the shape of the shaft portion of the light shielding fin is different from each other, but one of the shapes of the shaft portion of the light shielding fin in each embodiment is used. do it.

  In any of the second to sixth embodiments, it is preferable to provide a side cover as in the first embodiment. For this reason, the lateral width of the light shielding fin is larger than the lateral width of the mounting frame. However, it is preferable that the side cover has a height so that the claw portion of the side cover and the cutout of the support member do not impede the rotating operation.

  Thus, in the roll screen of each embodiment, in order to pivotally support the shaft portion 91 of the light shielding fin, the bearing portion 20 can be provided on the lower rear side or the bottom surface side of the mounting frame 2.

  Further, as a modification of the roll screen of each embodiment, as shown in FIG. 16A, a winding pipe 3 that can wind up the screen 4 is supported by support members 2a and 2b, and an attachment frame is used. It can be set as the roll screen 1f comprised so that support member 2a, 2b may be fixed to a ceiling surface, without. In this case, the light shielding fins in the respective embodiments such as the light shielding fin 9 described above can be provided by being pivotally supported by the support members 2a and 2b. For example, FIG. 16B shows a configuration example when the light shielding fin 9 of the first embodiment is pivotally supported by the support members 2a and 2b as a representative. The support members 2a and 2b are constituted by plate-like members bent in a substantially U shape so as to be fixed to the ceiling surface, and each has a round hole-shaped shaft support portion 24 formed. The cylindrical shaft 25 is supported by the round hole-shaped shaft support portions 24 of the support members 2a and 2b. By supporting the shaft portion 91 of the light shielding fin 9 on the cylindrical shaft 25, the functions and effects of the light shielding fin 9 of the first embodiment described above can be exhibited.

  In the roll screen 1f, various modifications are possible for the form in which the light shielding fins 9 are pivotally supported. For example, a cylindrical shaft protruding at a predetermined length may be fixed to each of the support members 2a and 2b, and the light shielding fins 9 may be pivotally supported on these cylindrical shafts, or the light shielding fins 9c configured by the shaft portions 91 having a round shaft shape. Alternatively, the shaft portion 91 having a round shaft shape may be protruded from both left and right ends, and supported by the shaft support portion 24 provided on the support members 2a and 2b. FIG. 16A shows an example in which the screen 4 can be lifted and lowered by the operation cord 7 as in the first embodiment. However, the pull grip 12 is lifted and lowered as in the second embodiment. It can be configured to allow operation. Also in the embodiment shown in FIG. 16, it is preferable to provide a side cover as in the first embodiment.

  Preferably, the light-shielding fin in each of the embodiments is arranged so that the screen 4 is suspended from the winding pipe 3 to the lower limit position (for example, between the mounting frame 2 and the winding pipe 3). The light shielding property can be enhanced by covering all the gaps between the ceiling and the take-up pipe 3).

  Preferably, the light-shielding fin in each embodiment is configured to be in non-contact with the winding pipe 3 and / or the screen 4 in a state where the screen 4 is suspended from the winding pipe 3 to the lower limit position. In a state where the light shielding property is enhanced, damage that may occur due to contact with the winding pipe 3 or the screen 4 can be prevented.

  Further, preferably, the light shielding fin in each embodiment is configured to be in non-contact with the winding pipe 3 and / or the screen 4 in a state where the screen 4 is at the upper limit position, thereby improving the light shielding property. Thus, damage that may occur due to contact with the winding pipe 3 or the screen 4 can be prevented.

  Preferably, as described as an example of the above-described embodiment, the shaft portion 91 (or 91a) of the light shielding fin is configured to be pivotally supported in the vicinity of the front end edge or the rear end edge of the mounting frame 2. Thus, while preventing the damage caused by the contact with the winding pipe 3 and the screen 4 in the state where the light shielding property is enhanced, the necessary distance associated with the rotation of the light shielding fin is minimized, that is, the necessary installation area. Can be reduced.

  Furthermore, preferably, as described as an example of the above-described embodiment, a piece (in the example of the above-described embodiment) that pivotally supports the mounting frame 2 while restricting the rotation of the shaft portion 91 (or 91a) of the light shielding fin. , Which are rotation restricting pieces 20a and 20b extending from below or above the attachment frame 2 and having a round shaft 20e or a bending shaft 20f formed at the tip). The backlash and sound can be reduced. As shown in FIG. 16, even when the light shielding fin is pivotally supported by the support members 2a and 2b without using the mounting frame 2, the shaft portion 91 (or 91a) of the light shielding fin is supported by the support members 2a and 2b. The protruding piece for guiding the rotation can be formed by protruding with a predetermined length.

  Further, preferably, as described as an example of the above-described embodiment, the weight 4 is configured so that the winding of the screen 4 by the winding pipe 3 is stopped by the contact of the weight bar 5 with the mounting frame 2. It is possible to reduce jumping of the light shielding fin due to contact with the bar 5.

[Rotation deceleration part and rotation restriction part]
Next, a configuration of a roll screen for supporting the light shielding fin 9 on the mounting frame 2 so that the light shielding fin 9 is not in contact with the screen 4 even at the maximum winding diameter, and the light shielding fin 9 is the weight bar 5 of the screen 4. A configuration of a roll screen that pivotally supports the light shielding fin 9 on the mounting frame 2 so as to rotate gently due to interference with the mounting frame 2 will be described.

  For example, the screen 4 may be constituted by a sled formed by weaving a relatively hard and long cylindrical material such as a bamboo cylinder. Since such a sag is uneven, if the light shielding fin 9 is pivotally supported on the mounting frame 2 so as to be always in contact with the light shielding fin 9 to shield the light, the screen 4 with the light shielding fin 9 and the sled are removed when the screen 4 is wound. The contact sound due to the friction of the light and the contact sound with the mounting frame 2 due to the shakiness of the light shielding fins 9 are relatively large, which may cause discomfort to the operator.

  Therefore, in order to further reduce the contact sound, it is preferable to provide a rotation restricting portion 80 that can restrict the rotation of the light shielding fin 9, and instead of or in addition to this, the light shielding fin 9. It is preferable to provide a rotation speed reducing portion 81 that reduces the speed during rotation. Hereinafter, with reference to FIGS. 17 and 18, the rotation restricting unit 80 and the rotation speed reducing unit 81 will be described in order. FIG. 17A is a side view of the light shielding fin 9 in the roll screen according to the first embodiment of the present invention when the rotation restricting portion 80 and the rotation speed reducing portion 81 are not provided, while FIG. FIG. 7B is a side view when the rotation restricting portion 80 and the rotation speed reducing portion 81 are provided with respect to the light shielding fin 9. FIG. 18 is a diagram illustrating the positions of the rotation restricting portion 80 and the rotation speed reducing portion 81.

  In the following description, the rotation restricting portion 80 is mainly configured as a member that can be affixed to the mounting frame 2, and the rotation speed reducing portion 81 is a member that can be affixed to the shaft portion 91 of the light shielding fin 9. A configured example is given.

(Rotation restriction part)
First, referring again to the operation of the above-described embodiment, in the case of the screen 4 made of a soft cloth in the roll screen of the first embodiment shown as a representative in FIG. At the time of the arrow H) shown in FIG. 17 (a) or in the fully closed state, the cloth contact portion 94 of the light shielding fin 9 is brought into contact with the peripheral surface of the screen 4 (shown in FIG. When the shaft portion 91 is pivotally supported by the bearing portion 20 of the mounting frame 2, the light shielding property can be improved. As long as light leakage can be ignored, the fabric contact portion 94 of the light shielding fin 9 is not necessarily in contact with the peripheral surface of the screen 4, and the light shielding fin 9 may be configured in a close proximity.

  That is, in the case of the screen 4 made of a soft cloth, the lower projection 98 of the light shielding fin 9 abuts or approaches the rotation restricting piece 20a in the bearing portion 20 of the mounting frame 2 at the maximum winding diameter. As shown (shown in FIG. 17A), the light shielding fins 9 may be configured. Further, in the case of the screen 4 made of a soft cloth, as described above with reference to FIG. 3, the shaft portion 91 of the light shielding fin 9 has a spatial margin with respect to the bearing portion 20 of the mounting frame 2. (Fig. 17C in FIG. 17A) makes it difficult for the light shielding fin 9 to come off from the bearing portion 20, increases the degree of freedom of rotation of the light shielding fin 9, and changes the thickness of the shaft portion 91. A curved portion 92 having a thickness in the moving range is formed. For this reason, the unpleasant interference sound (contact sound) resulting from the rotation interference of the light shielding fin 9 and the rotation restricting piece 20b can be reduced to a negligible level.

  On the other hand, when the screen 4 is constituted by a sled formed by weaving a relatively hard and long tubular material such as a bamboo cylinder, the light shielding is performed regardless of the maximum winding diameter or the fully closed state. If the shaft portion 91 of the light shielding fin 9 is pivotally supported by the bearing portion 20 of the mounting frame 2 so that the fabric contact portion 94 of the fin 9 is brought into contact with the peripheral surface of the screen 4, particularly when the screen 4 is wound, the screen 4. As the wire is wound, the contact sound caused by rubbing between the light-shielding fin 9 and the screen 4 due to the unevenness of the unevenness is relatively large, and the operator feels uncomfortable.

  Therefore, as shown in FIG. 17 (b), when the screen 4 is configured by sliding, a member constituting the rotation restricting portion 80 is attached to the rotation restricting piece 20a in the bearing portion 20 of the mounting frame 2, Even at the maximum winding diameter of the screen 4 (arrow H shown in FIG. 17B), the fabric contact portion 94 of the light shielding fin 9 does not come into contact with the peripheral surface of the screen 4 (D shown in FIG. 17B). ) Adjust the angle of the light shielding fin 9. The member which comprises such a rotation control part 80 can be made into the seal | sticker form which formed in the sheet shape by arbitrary shapes with the synthetic resin, and apply | coated the adhesive to the one surface.

  And although the member which comprises this rotation control part 80 may be affixed over substantially the full length of the left-right direction width of the attachment frame 2, it seems to be scattered in several places by the left-right direction width of the attachment frame 2. Affix it. For example, as shown in an exaggerated manner in FIG. 18, members constituting the rotation restricting portion 80 may be pasted at a total of three locations in the vicinity of both ends in the left-right direction of the mounting frame 2 and the central portion. Further, it is preferable to prepare a plurality of types of thicknesses of the members constituting the rotation restricting portion 80 according to the thickness of the fabric of the sag, and it is desirable to form the seals so that they can be pasted together. Accordingly, considering that the light leakage at the maximum winding diameter of the screen 4 and the fully closed state is made small enough to be ignored, the fabric contact portion 94 in the light shielding fin 9 is formed by the members constituting the rotation restricting portion 80. And the peripheral surface of the screen 4 can be adjusted.

  The member constituting the rotation restricting portion 80 may be attached to the lower protrusion 98 of the light shielding fin 9 instead of being attached to the rotation restricting piece 20a in the bearing portion 20 of the mounting frame 2. The mounting frame 2 and / or the light shielding fins 9 to which the rotation restricting portion 80 is applied are not necessarily limited to the case where the screen 4 is configured by sliding, but can also be used in the case of the screen 4 configured by a soft cloth.

(Rotation reduction part)
Next, the rotation speed reducing unit 81 will be described in detail. In a state in which the shaft portion 91 of the light shielding fin 9 is engaged with the bearing portion 20 of the mounting frame 2 with a spatial margin (shown in FIG. 17A), for example, a bamboo cylinder or the like When the screen 4 is constituted by a sled formed by weaving a hard and long cylindrical material, the shading unevenness of the sled causes the light shielding fin 9 to flutter. A large contact noise with the two bearing portions 20 may occur.

  Therefore, as shown in FIG. 17B, when the screen 4 is configured by sliding, a member constituting the rotation speed reducing portion 81 is attached to the curved portion 92 of the shaft portion 91 of the light shielding fin 9 to rotate. It is made to contact with the control piece 20b. A member constituting such a rotation speed reducing portion 81 can be a foamed rubber tape which is formed into a sheet shape with an arbitrary shape using foamed rubber, and a pressure-sensitive adhesive is applied to one surface thereof. The rotation speed reducing portion 81 comes into contact with the rotation restricting piece 20b of the mounting frame 2 and gradually rotates even when the light shielding fin 9 rotates due to the contact between the light shielding fin 9 and the weight bar 5. Furthermore, it is possible to suppress the fluttering of the light shielding fins 9 by exhibiting a damper action that reduces vibrations when the light shielding fins 9 are rotated. The members constituting the rotation speed reducing portion 81 may be applied over almost the entire length of the mounting frame 2 in the left-right direction, but are attached so as to be scattered at a plurality of positions in the width of the mounting frame 2 in the left-right direction. That's fine. For example, as shown in an exaggerated manner in FIG. 18, members constituting the rotation speed reducing portion 81 may be attached at a total of two locations in the vicinity of both end portions in the left-right direction of the mounting frame 2. Further, the shading fin 9 can be configured by integrally molding the shaft portion 91 (more specifically, the curved portion 92 in the shaft portion 91) and the rotation speed reducing portion 81 by two-color molding.

  By forming the member constituting the rotation speed reducing portion 81 from foamed rubber, the light shielding fin 9 does not easily come off from the bearing portion 20, and the rotation degree of the light shielding fin 9 is not impaired. It can be reduced to such an extent that an unpleasant interference sound (contact sound) can be ignored due to the rotational interference of the regulating piece 20b. Therefore, the light-shielding fin 9 to which the rotation speed reducing unit 81 is applied is not necessarily limited to the case where the screen 4 is configured by sliding, but can also be used in the case of the screen 4 configured by a soft cloth.

  Further, the rotation speed reducing portion 81 that produces the above-described action may be constituted by a grease damper or an oil damper, in addition to being constituted by a member such as foam rubber or foam rubber tape.

  As described above, by providing the rotation restricting portion 80 and / or the rotation speed reducing portion 81, the roll screen can be configured to reduce the contact sound related to the light shielding fins 9.

  As a separate member, the lower side of the light shielding fin 9 is provided so as to have the function of the rotation restricting portion 80 without providing the rotation restricting portion 80 on one or both of the light shielding fin 9 and the mounting frame 2. The protrusion 98 and / or the rotation restricting piece 20a of the mounting frame 2 may be formed. For example, FIG. 19 is a side view for explaining a light shielding fin 9 of a modification of the roll screen according to the first embodiment of the present invention. The example shown in FIG. 19 is an example in which the lower protrusion 98 of the light shielding fin 9 has the function of the rotation restricting portion 80 described above as compared with the configuration shown in FIG. In this example, not only when the lower protrusion 98 is in the fully closed state of the screen 4 (broken line state shown in FIG. 19), but also when the maximum winding diameter of the screen 4 (arrow H shown in FIG. 19) is used. The lower protrusion 98 protrudes below the light shielding fin 9 so that the fabric contact portion 94 of the light shielding fin 9 does not contact the peripheral surface of the screen 4, and the angle of the light shielding fin 9 is adjusted. The lower protrusion 98 functions as the rotation restricting portion 80.

  In particular, the light shielding fins 9 are arranged in the vertical direction so as to prevent direct incident light between the mounting frame 2 and the take-up pipe 3 from at least an elevation angle of 0 ° or more and not to contact the screen 4 from a lower limit to a predetermined height. By pivotally supporting it in a movable manner (including linear movement and rotation in the vertical direction), the light leakage can be effectively shielded, and the contact sound related to the light shielding fin 9 can also be reduced.

  Preferably, as described above, the contact sound related to the light shielding fin 9 can be reliably reduced by making the light shielding fin 9 non-contact with the screen 4 even at the maximum winding diameter.

  In the configuration shown in FIG. 17B and FIG. 19, the case of the light shielding fin 9 shown in FIG. 3 has been described as an example. However, the functions of the rotation restricting portion 80 and the rotation speed reducing portion 81 are provided. Such a roll screen can be applied to the above-described light shielding fins 9a, 9b, 9c, and 9d.

  In the configuration shown in FIGS. 17B and 19, the fabric contact portion 94 does not contact the peripheral surface of the screen 4, but is raised in a curved shape as shown in the figure, so that light leakage is suppressed. Note that the shape is suitable. Accordingly, the fabric contact portion 94 is configured as a “curved bulge portion” that does not necessarily require such contact with the peripheral surface of the screen 4.

[Seventh Embodiment]
Here, in each embodiment mentioned above and its modification, it can also be set as the structure which arrange | positions the light-shielding fin 9 (or 9a) in the front side (indoor side). For example, an example in which the light shielding fins 9 shown in FIG. 3 are arranged indoors with respect to the roll screen 1 of the first embodiment will be described below as a seventh embodiment.

  Further, when the light shielding fin 9 is provided so as to cover at least a part of the operation pulley 8, as shown in FIG. 21B, for example, the operation code 7 is changed from the non-operation state shown in FIG. When the screen 4 is wound up by the take-up pipe 3 by pulling the front side (interior side) at an angle, the operation cord 7 comes into contact with the cloth contact portion (curved ridge portion) 94 of the light shielding fin 9. However, since the light shielding fin 9 rotates, the pulling operation is not hindered.

  Further, since the cloth contact portion (curved bulge portion) 94 of the light shielding fin 9 has a shape raised to the curved surface, even if the operation cord 7 comes into contact with the light shielding fin 9, the frictional resistance is reduced. Thus, the load required for the pulling operation is not greatly increased. In addition to the braid, the operation cord 7 includes a ball chain in which a large number of balls are fixed to the string and a metal chain in which a rosary is connected.

  In the roll screen 1 of the seventh embodiment, when the screen 4 wound up by the winding pipe 3 by the pulling operation reaches a predetermined winding diameter, the operation cord 7 does not come into contact with the light shielding fins 9, and the light shielding fins 9 Since it rotates according to winding of the screen 4, the function of the light shielding fin 9 and its operability are not hindered. For example, the non-operating screen 4 when the weight bar 5 is at the upper limit position is in a state as shown in FIG.
