Hereinafter, the roll screen 1 as a shielding device according to an embodiment of the present invention will be described with reference to the drawings. In the specification of the present application, with respect to the front view of the roll screen 1 shown in FIG. 1, the upper side and the lower side in the drawing are upward (or upper) and lower (or lower), respectively, according to the hanging direction of the screen 4. ), The left direction in the drawing is defined as the left side of the roll screen 1, and the right direction in the drawing 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 side to be visually recognized is the front side (or the indoor side), and the opposite side is the rear side (or the outdoor side). When referred to as the front-rear direction, the direction perpendicular to the illustrated surface in the front view of FIG. 1 is referred to.

(overall structure)
First, the configuration of the roll screen 1 as the shielding device of the embodiment according to the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a front view showing a schematic configuration of a roll screen 1 according to the present invention, and FIG. 2 is a side perspective view of the roll screen 1 according to the present invention.

In the roll screen 1 shown in FIG. 1, support members 2a and 2b are fixed to both ends of the mounting frame 2, and a shaft member 11 is fixed to the support members 2a and 2b. (Not shown) rotatably supports the cylindrical take-up pipe 3 between the support members 2a and 2b. The mounting frame 2 is fixed to the mounting surface by the bracket 6. Each of the support members 2a and 2b is accommodated by the side cover 10, and as will be described later, the design and the functionality related to the rotational operation of the light-shielding fin 9 are improved.

An operation pulley 8 is provided at the right end of the take-up pipe 3, and an endless operation cord 7 hung around the operation pulley 8 is hung. In this example, the operation code 7 is composed of a ball chain, and the surface of the operation pulley 8 on which the ball chain is hung is configured to have irregularities having a shape suitable for the ball portion of the ball chain. .. Then, the take-up pipe 3 can be rotated by operating the operation code 7. Further, the operation cord 7 composed of a ball chain has an endless shape in which the end portions of the cords are connected by the cord connecting member 7a. The operation code 7 may be in the shape of a string, and the surface of the operation pulley 8 on which the operation code 7 is hung may have a surface shape with high friction.

The take-up pipe 3 attaches one end of the screen 4 to take up the screen 4 or suspends and supports the screen 4 so that it can be rewound. The other end of the screen 4 is attached to a weight bar 5 that functions as a weight member. Therefore, the screen 4 is stretched based on the weight of the weight bar 5. In the example of the present embodiment, the screen 4 is hung from the outdoor side of the take-up pipe 3 (see FIG. 2).

Then, when the operation code 7 is operated to rotate the winding pipe 3 in the screen winding direction, the weight bar 5 rises, and when the winding pipe 3 is rotated in the screen rewinding direction, the weight bar 5 lowers. A movement limiting member 12 can be attached on the operation code 7 composed of a ball chain, and the movement limiting member 12 can bring the movement limiting member 12 into contact with the operation pulley 8 or the like to stop the rotation of the weight. The form may be such that the upper limit position of the bar 5 is determined.

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

Here, in the roll screen 1 according to the present invention, the light-shielding fin 9 having a structure that allows the predetermined fabric 13 to be easily attached is attached to the front side (front side) of the attachment frame 2 and is attached to the take-up pipe 3. It is designed to effectively block light leakage from the gap between the mounting frame 2 and the mounting frame 2. As shown in FIG. 2, the details will be described later, but the shaft portion 91 of the light-shielding fin 9 is engaged with the bearing portion 20 provided on the front side of the mounting frame 2, whereby the light-shielding fin 9 is mounted. It is rotatably supported within a predetermined range on the front side (front side) of the frame 2. Hereinafter, the light-shielding fin 9 of one embodiment will be described in detail.

(Composition of shading fins)
FIG. 3 shows the configuration of the light-shielding fin 9 of one embodiment in the roll screen 1 of the present embodiment. Further, FIG. 4 is an exploded perspective view showing a schematic configuration around a light-shielding fin 9 of an embodiment of the roll screen 1 of the present embodiment.

With reference to both FIGS. 3 and 4, the light-shielding fin 9 has a substantially L-shaped cross-sectional shape as a whole, and is rotatably locked on the front side (front side) of the mounting frame 2. The light-shielding fins 9 are preferably formed of a synthetic resin having a high light-shielding property, aluminum, or the like, but when the fabric 13 is attached as in this example, the light-shielding fins 9 may be made of a transparent or translucent synthetic resin.

The left-right width of the light-shielding fins 9 is slightly shorter than the left-right width of the mounting frame 2. For example, when the light-shielding fins 9 are made of synthetic resin, the left-right width is due to thermal expansion or the like. Is changed so that it can be locked smoothly and rotatably.

A bearing portion 20 having a substantially C-shaped cross section extending in the longitudinal direction thereof is formed below the front 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 surface side of the mounting frame 2. Support members 2a and 2b are attached to both ends of the attachment frame 2 in the longitudinal direction.

The support members 2a and 2b are configured to have the same shape, and as shown in FIG. 4, a notch 23 having a size substantially matching the substantially C-shaped cross-sectional shape of the bearing portion 20 of the mounting frame 2 is provided. .. The notch 23 is provided to allow the support members 2a and 2b to be supported by being inserted into the bearing portion 20 by sliding the shaft portion 91 of the light-shielding fin 9 from the left-right direction after fixing the support members 2a and 2b to the mounting frame 2. ing. Then, the light-shielding fins 9 are slid to be removable, and other than this slide is non-removable so that the light-shielding fins 9 cannot be removed from the mounting frame 2 even if an external force is applied to the light-shielding fins 9.

Further, the support members 2a and 2b have a screw hole 21 for fixing the mounting frame 2 using mounting screws, and a shaft member 11 having a fixing shaft (not shown) that rotatably supports the take-up pipe 3. Screw holes 22 for fixing (see FIG. 1) are provided at a plurality of places. That is, even after the support members 2a and 2b are fixed to the mounting frame 2 in a state where the take-up pipe 3 is supported by the support members 2a and 2b, the shaft portion 91 of the light-shielding fin 9 is slid from the left-right direction to the bearing portion 20. It can be supported by inserting it into. Therefore, the light-shielding fin 9 can be easily attached.

Further, the side cover 10 is attached from the viewpoint of improving the design by making the mounting screws of the screw holes 21 and 22 of the support members 2a and 2b invisible from the outside. It also has an effect of improving the functionality related to the rotational operation of the light-shielding fin 9.

That is, the side cover 10 has a wall having a height so as to regulate the positions of both ends of the light-shielding fins 9 in the left-right direction within the rotation range of the light-shielding fins 9 so that the light-shielding fins 9 can rotate smoothly. Part 10a is formed. The height of the wall portion 10a is sufficiently high to accommodate the thicknesses of the support members 2a and 2b. The side cover 10 is made of synthetic resin so that it can be attached to the wall portion 10a with a narrow pressure according to the outer shape of the support members 2a and 2b formed of a metal material, and the support members 2a and 2b are attached to the wall portion 10a. A claw portion 10b is formed so as to project inward so that the metal can be gripped. As a result, the wall portion 10a is provided with a height so that the claw portion 10b and the notch 23 do not hinder the rotational operation of the light-shielding fin 9.

That is, the left and right ends of the light-shielding fins 9 come into contact with the wall portion 10a of the side cover 10 before they come into contact with the support members 2a and 2b, so that the light-shielding fins 9 are rotatably regulated at their locking positions. By restricting both ends of the light-shielding fin 9 in the left-right direction, the design of the light-shielding fin 9 is ensured, and the harmful effect of rotation can be prevented while enhancing the light leakage effect. In this example, the width of the light-shielding fin 9 in the left-right direction is slightly shorter than the width of the mounting frame 2 in the left-right direction, and the wall portion 10a of the side cover 10 regulates the light-shielding fin 9 so as to be rotatable. Although an example is shown, the support members 2a and 2b and the side cover 10 may be avoided depending on the shape of the light-shielding fin 9.

As shown in FIG. 3, a bearing portion 20 having a substantially C-shaped cross section extending in the longitudinal direction thereof is formed below the front surface of the mounting frame 2. More specifically, the bearing portion 20 forms a bent shaft 20f at the tip of the 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 20a has a function of restricting the downward rotation of the light shielding fin 9. Further, above the bearing portion 20 on the back surface of the mounting frame 2, a rotation restricting piece 20b that restricts the upward rotation of the light-shielding fin 9 is formed. In the illustrated example, the rotation restricting piece 20a is formed in a substantially C shape protruding forward from the front surface of the main body of the mounting frame 2, and the rotation restricting piece 20b is formed in a substantially plate shape protruding rearward. When the shaft portion 91 of the light-shielding fin 9 is locked to the bearing portion 20, the vertical rotation of the light-shielding fin 9 is restricted, and no matter how the light-shielding fin 9 is rotated, the light-shielding fin 9 is rotated in the back direction. It is designed so that it does not come off from the bearing portion 20.

The light-shielding fin 9 has, as a general configuration, a support plate portion 93 having a substantially C-shaped shaft portion 91 at the tip thereof and projecting forward from the front side surface of the mounting frame 2 by a length a, and the support plate. The shielding plate portion 94 extending downward from the portion 93 with a length b has a substantially L-shaped cross-sectional shape as a whole, and causes collision force and contact noise due to interference with the screen 4 (or a weight bar 5 described later). It is formed of a compound curved member (either a single member or a decoding member) so as to avoid or relax.

More specifically, the support plate portion 93 has a substantially L-shaped bent shape, and a substantially C-shaped shaft portion 91 is formed at the tip thereof. The shaft portion 91 is a portion of the bearing portion 20 that is rotatably locked by the bent shaft 20f. The tip of the shaft portion 91 is formed in a substantially hook shape bent at an acute angle, and by engaging the bearing portion 20 with a space margin, the light-shielding fins 9 are prevented from coming off from the bearing portion 20. , The degree of freedom of rotation of the light-shielding fin 9 is increased.

On the other hand, when the shaft portion 91 of the light-shielding fin 9 is locked to the bearing portion 20 in such a manner that the degree of freedom of rotation is increased, an unpleasant interference sound (unpleasant interference sound) due to rotation interference between the light-shielding fin 9 and the rotation control piece 20b In order to generate a contact sound), the shaft portion 91 is formed with a curved portion 92 having a wall thickness in the rotation range by changing the thickness.

Further, a contact portion 97 is formed in the vicinity of the base of the shaft portion 91 provided at the tip of the support plate portion 93. The contact portion 97 is a portion that restricts the upward rotation of the light-shielding fin 9 by abutting with the rotation restricting piece 20b, which will be described in detail later.

The shape of the shaft portion 91 makes it difficult for the light-shielding fin 9 to come off from the bearing portion 20, and allows the light-shielding fin 9 to rotate while suppressing rattling and reducing the interference noise. ing. As a result, the unpleasant interference sound (contact sound) caused by the rotation interference between the contact portion 97 and the rotation restricting piece 20b can be reduced to a negligible level.

Further, a protrusion 98 is formed below the shaft portion 91 provided at the tip of the support plate portion 93, and the protrusion 98 projects from the support plate portion 93 along with the shaft portion 91. The protrusion 98 is a portion that restricts the downward rotation of the light-shielding fin 9 at a position where the bearing portion 20 of the mounting frame 2 abuts on the rotation restricting piece 20a, which will be described in detail later. In particular, the tip of the protrusion 98 is configured to have an uneven step as shown in the figure, and has a function of acting to alleviate the contact noise and the collision force at the time of contact with the rotation restricting piece 20a. Although the protrusion 98 of this example is formed so as to extend and project in the left-right direction of the support plate portion 93, it may be in a form of partially projecting in the left-right direction of the support plate portion 93.

A curved interference mitigation portion 95 is formed at the lower end of the shielding plate portion 94 extending downward from the support plate portion 93. Even when there is contact with the screen 4 (or the weight bar 5 in the embodiment described later), the interference mitigation unit 95 warps in a direction away from the screen 4 (or the weight bar 5) so as to alleviate the contact sound and the collision force. Has a shape.

Further, protrusions 96a and 96b protruding in a substantially hook cross-sectional shape are provided at the upper end and the lower end of the front surface of the shielding plate portion 94, respectively, to form recesses for engaging the upper end and the lower end of the cloth 13. In particular, a claw portion 99 is formed inside the protrusion 96a at the upper end of the front surface of the shielding plate portion 94, and the protrusion 96a and the claw portion 99 are configured as a gripping means that functions as a cloth retainer. On the other hand, the protrusion 96b at the lower end of the front surface of the shielding plate portion 94 is a portion for suppressing the fluttering of the fabric 13, and a concave portion for suppressing the fluttering and not pressing is formed. The description regarding the attachment of the fabric 13 will be described in detail later.

(Lower and upper rotation regulation structure of light-shielding fins)
5 (a) and 5 (b) are side views for explaining the operation of the light-shielding fin 9 of one embodiment in the roll screen 1 of the present embodiment, and in particular, FIG. 5 (a) shows the bottom of the light-shielding fin 9. Regarding the side rotation regulation, FIG. 5B is illustrated with respect to the upper rotation regulation of the light-shielding fin 9.

As shown in FIG. 5A, a protrusion 98 is formed below the shaft portion 91 provided at the tip of the support plate portion 93, and the protrusion 98 is aligned with the shaft portion 91 and is a support plate. It protrudes from the portion 93. The light-shielding fin 9 is rotatably locked by the bent shaft 20f in the bearing portion 20 by the shaft portion 91. The protrusion 98 provided on the light-shielding fin 9 has a function of restricting the downward rotation of the light-shielding fin 9 at a position where the bearing portion 20 of the mounting frame 2 comes into contact with the rotation restricting piece 20a. At this time, the light-shielding fin 9 is regulated so that the longitudinal direction of the shield plate portion 94 of the light-shielding fin 9 is substantially perpendicular to the front-rear direction of the mounting frame 2 (hanging in the vertical direction) as its basic posture. .. As described above, as a basic posture when the light-shielding fins 9 are attached to the mounting frame 2 of the roll screen 1, the longitudinal direction of the shielding plate portion 94 of the light-shielding fins 9 is substantially perpendicular to the front-rear direction of the mounting frame 2 (in the vertical direction). Since it becomes a hanging), its design is improved.

Further, as shown in FIG. 5B, a contact portion 97 is formed in the vicinity of the base of the shaft portion 91 provided on the light-shielding fin 9. The contact portion 97 is a portion that restricts the upward rotation of the light-shielding fin 9 by contacting the rotation restricting piece 20b when the light-shielding fin 9 rotates from the basic posture. As a result, the light-shielding fins 9 are not in contact with the bracket 6 and its mounting surface. In this way, the quality of the light-shielding fins 9 can be maintained without impairing the operability when the light-shielding fins 9 are attached to the attachment frame 2 of the roll screen 1.

(How to attach the fabric to the light-shielding fins)
FIG. 6A is a side view showing a structure related to attachment of the fabric 13 of the light-shielding fin 9 of one embodiment in the roll screen 1 of the present embodiment, and FIG. 6B shows a comparative example thereof. There is. Further, FIGS. 7A, 7B, and 7C show an example of a method of attaching the fabric 13 of the light-shielding fin 9 of one embodiment in the roll screen 1 of the present embodiment.

First, as shown in FIG. 6A, the light-shielding fins 9 according to the present embodiment are provided with protrusions 96a and 96b protruding in a substantially hook cross-sectional shape at the upper and lower ends of the front surface of the shield plate portion 94, respectively. , A recess is formed to engage the upper and lower ends of the fabric 13. In particular, a claw portion 99 is formed inside the protrusion 96a at the upper end of the front surface of the shielding plate portion 94, and the protrusion 96a and the claw portion 99 are configured as a gripping means that functions as a cloth retainer. On the other hand, the protrusion 96b at the lower end of the front surface of the shielding plate portion 94 is a portion for suppressing the fluttering of the fabric 13, and a concave portion for suppressing the fluttering and not pressing is formed.

For example, when attaching the fabric 13 to the light-shielding fins 9 according to the present embodiment, it is possible to insert and attach the fabric 13 from the left and right end sides of the light-shielding fins 9, but it is better to attach the fabric 13 from the front side of the light-shielding fins 9. It is easier to install. For example, as shown in FIG. 7, the upper end of the fabric 13 is first engaged by the protrusion 96a and the claw portion 99 (see FIG. 7A), and then the lower end of the fabric 13 is formed into the recess formed by the protrusion 96b. Insert (see FIG. 7 (b)). In this way, the fabric 13 can be easily attached to the light-shielding fin 9. Further, since the light-shielding fin 9 according to the present embodiment has a structure in which only the upper end of the fabric 13 is engaged, the fabric 13 does not bend and its design can be improved. Further, even if the fabric 13 is displaced in the vertical direction due to the rotational operation of the light-shielding fins 9 due to the protrusions 96a and 96b at the upper and lower ends of the front surface of the shielding plate portion 94, its function and design are not impaired. ..

Then, the fabric 13 is temporarily attached to the light-shielding fin 9 by sticking or the like, and the claw portion 99 is also provided at the lower end of the front surface of the shielding plate portion 94 as shown in FIG. When the holding means is configured, the fabric 13 is bent, and a large work load is generated when mounting so as to eliminate the bending. Therefore, it is preferable to have a structure in which only the upper end of the fabric 13 is engaged, as in the light-shielding fin 9 according to the present embodiment, and the fabric 13 can be easily attached without causing bending.

(Operation of light-shielding fins and versatility)
8 (a), (b), and (c) are side views for individually explaining an operation example of the light-shielding fin 9 of one embodiment in the roll screen 1 of the present embodiment, respectively.

As shown in FIG. 8A, the light-shielding fins 9 of this embodiment have a support plate portion 93 that bends forward from the front side surface of the mounting frame 2 by a length a and protrudes, and a support plate portion 93 that protrudes downward from the support plate portion 93. Due to the shielding plate portion 94 extending by the length b, it has a substantially L-shaped cross-sectional shape as a whole.

The length b of the shielding plate portion 94 is formed to prevent light leakage caused by a gap between the mounting frame 2 and the take-up pipe 3. The length a of the support plate portion 93 is set within a range that does not adversely affect the operation of the operation code 7. Even if the operation code 7 is operated so as to come into contact with the light-shielding fin 9 of the present embodiment, the light-shielding fin 9 rotates so as not to cause an operation load.

Further, as shown in FIG. 8B, when the light-shielding fin 9 of this embodiment is applied to the roll screen 1 in which the maximum winding diameter S of the screen 4 is relatively small, the screen 4 and the light-shielding fin 9 are formed. There is no contact, and as its basic posture, light is shielded while maintaining a state in which the longitudinal direction of the shield plate portion 94 of the light-shielding fin 9 is substantially perpendicular to the front-rear direction of the mounting frame 2 (a state in which it hangs down in the vertical direction). Can retain functionality.

On the other hand, as shown in FIG. 8C, when the light-shielding fin 9 of this embodiment is applied to the roll screen 1 in which the maximum winding diameter S of the screen 4 is relatively large, the screen 4 and the light-shielding fin 9 are formed. Even when they come into contact with each other, the light-shielding fins 9 can be rotated according to the thickness of the screen 4, and the light-shielding function can be maintained.

By the way, when the roll screen 1 is directly attached to the wall surface based on the conventional technique, there is a problem that the light-shielding fins 9 cannot be attached to the roll screen 1.

FIG. 9A shows an example when the roll screen 1 of the present embodiment is frontally attached to a wall surface (for example, a side wall surface) W, and FIG. 9B is a comparative example thereof.

As shown in FIG. 9A, the roll screen 1 of the present embodiment having the light-shielding fins 9 can be directly attached to the wall surface W by using the fixing metal fitting 61 (L-shaped metal fitting in this example). The fixing bracket 61 fixes the bracket 6 through the first mounting hole 61a of the fixing bracket 61 using a mounting screw, and is frontally attached to the wall surface W via the second mounting hole 61b of the fixing bracket 61. The mounting frame 2 of the roll screen 1 of the present embodiment can be attached to the bracket 6 fixed to the wall surface W by using the fixing bracket 61 in this way.

In particular, the fixing bracket 61 is configured to have a certain gap between the roll screen 1 and the wall surface W so that the roll screen 1 of the present embodiment is directly attached to the wall surface W. As a result, when the screen 4 is wound up and the weight bar 5 reaches the upper limit position, it is possible to prevent the weight bar 5 from colliding with the wall surface W.

That is, as shown in FIG. 9B, when the roll screen 1 is mounted on the front based on the conventional technique, the light-shielding fin 9 of the present embodiment cannot be attached to the roll screen 1, but it is fixed. By using the metal fitting 61 (L-shaped metal fitting in this example), the roll screen 1 of the present embodiment having the light-shielding fins 9 can be directly attached to the wall surface W.

Further, in the configuration in which the roll screen 1 of the present embodiment having the light-shielding fins 9 is directly attached to the wall surface W, the light-shielding fins 9 do not accumulate dust on the screen 4 that is wound up, so that the dust does not scatter during use. There is an effect.

Further, if the wound screen 4 is left for a long period of time, color deterioration unevenness of the screen 4 may occur due to direct external light, but the roll screen 1 of the present embodiment having the light-shielding fins 9 is mounted on the wall surface. In the configuration mounted on the front of the W, the light-shielding fins 9 can surely prevent direct light from the screen 4 in the vicinity of the mounting frame 2, and can improve the color resistance to the screen 4.

Further, in the roll screen shown in FIG. 9, since the light-shielding fins 9 are pivotally supported by the bearing portion 20 provided on the mounting frame 2, when the mounting frame 2 is viewed from the front as in the case of fixing the mounting frame 2 to the ceiling surface. It is possible to improve the design of the.

Further, in the roll screen shown in FIG. 9, since the bearing portions 20 are continuously formed in the left-right direction of the mounting frame 2 as described with reference to FIG. 4, there is external interference or the like. Is not easily removed.

As a modification of the embodiment shown in FIG. 9, when the roll screen 1 is frontally attached to the wall surface W using the fixing bracket 61 (L-shaped bracket in this example) via the bracket 6, the light-shielding fin 9 is attached to the mounting frame. Instead of being supported by the bearing portion 20 of 2, the shape of the light-shielding fin 9 can be modified so that the light-shielding fin 9 is supported by the bracket 6 or the fixing metal fitting 61 (L-shaped metal fitting in this example). ..

For example, FIGS. 10 (a) and 10 (b) show an example in which the roll screen 1 as a shielding device of the modified example according to the present invention is mounted on the wall surface in front. In FIGS. 10 (a) and 10 (b), the same reference numbers are assigned to the same components as those in the above-described embodiment.

First, in the modified example shown in FIG. 10A, in the shape of the light-shielding fin 9 shown in FIG. 3, instead of providing the substantially C-shaped shaft portion 91 at the tip of the support plate portion 93, the support plate portion 93 is concerned. It is assumed that the tip is L-shaped bent so as to have a portion 93a that faces upward and a portion 93b that faces backward through this portion 93a. The portion 93a can be a plate-like body that is shielded over almost the entire area in the left-right direction of the roll screen 1 from the viewpoint of design, but is not limited to the portion 93a. The portion 93b is a portion for fixing together with the bracket 6 by using the fixing bracket 61 (L-shaped bracket in this example), and is a plate-shaped piece that can be fixed by the fixing bracket 61, or is fixed by the fixing bracket 61. A plate-like body can be formed in which a notch is provided to enable the roll screen 1 and the roll screen 1 is substantially shielded over almost the entire area in the left-right direction.

The light-shielding fin 9 of the modified example shown in FIG. 10A is configured to be non-rotatable unlike the light-shielding fin 9 shown in FIG. 3, but the support plate portion 93 shown in FIG. 10A is The function of the light-shielding fins 9 shown in FIG. 3 is the same as that of the roll screen 1 in that it is configured to bend forward from the main body of the roll screen 1 so as to protrude and connect to the shield plate portion 9, and a certain amount of thickness of the screen 4 can be increased. It is permissible, and the collision force and contact noise due to interference with the screen 4 (or the weight bar 5 described later) can be avoided or alleviated.

On the other hand, in the modification shown in FIG. 10B, among the shapes of the light-shielding fins 9 shown in FIG. 3, the substantially C-shaped shaft portion 91 provided at the tip of the support plate portion 93 is deformed as shown in the drawing, and is also deformed. The suspension support member 62 for suspending and supporting the shaft portion 91 is used.

The suspension support member 62 is bent in an L shape so as to have a bearing portion 62c at the lower end thereof and to have a portion 62a that goes upward and a portion 62b that goes backward through this portion 62a. The function of the bearing portion 62c is the same as that of the bearing portion 20 provided on the front side of the mounting frame 2 for supporting the light-shielding fin 9 shown in FIG. Also in this example, the portion 62a can be a plate-like body that is shielded over almost the entire area in the left-right direction of the roll screen 1 from the viewpoint of design, although it is not limited. The portion 62b is a portion for fixing together with the bracket 6 by using the fixing bracket 61 (L-shaped bracket in this example), and is a plate-shaped piece that can be fixed by the fixing bracket 61, or is fixed by the fixing bracket 61. A plate-like body can be formed in which a notch is provided to enable the roll screen 1 and the roll screen 1 is substantially shielded over almost the entire area in the left-right direction.

The light-shielding fin 9 of the modified example shown in FIG. 10B is configured to be rotatable in the same manner as the light-shielding fin 9 shown in FIG. 3, and includes all the functions of the light-shielding fin 9 shown in FIG. To do.

Further, as a further deformation example, when the light-shielding fin 9 is supported by the bracket 6 or the fixing bracket 61, the shape of the bracket 6 or the fixing metal fitting 61 is deformed to support the light-shielding fin 9 rotatably or non-rotatably. It can also be configured to be. Therefore, the light-shielding fin 9 is configured to directly support the mounting frame 2, the bracket 6, or the fixing bracket 61, or a hanging support member 62 whose shape is appropriately adapted according to the application is used. It can be configured to be indirectly held.

Further, the light-shielding fins 9 may be provided for the purpose of shielding air permeability in addition to being provided for the purpose of blocking external light, and in this case, the light-shielding fins 9 may be made of a translucent material. In the specification of the present application, when the term "fin" is simply referred to, it includes various support forms such as the shapes illustrated in FIGS. 9 (a) and 10 (a) and 10 (b), and is used for various purposes such as light shielding and wind shielding. It shall refer to the shielding member of.

Therefore, by using the fixing metal fitting 61 (L-shaped metal fitting in this example), the roll screen 1 of the present embodiment having the fins can be directly attached to the wall surface W, and the fins prevent dust from scattering and the screen 4 It is possible to improve the color resistance against.

Further, FIGS. 11 (a), 11 (b), and 11 (c) show the configuration when the light-shielding fin 9 of this embodiment is applied to the roll screen 1 of another embodiment.

In the example shown in FIG. 11A, the screen 4 is hung from the take-up pipe 3 on the light-shielding fin 9 side of this embodiment, and the weight bar 5 is located between the light-shielding fin 9 and the take-up pipe 3. is there. In such a case, the light-shielding fin 9 of the present embodiment has a curved interference mitigation portion 95 formed at the lower end of the shielding plate portion 94 extending downward from the support plate portion 93, so that the light-shielding fin 9 interferes with the weight bar 5. Does not cause catching.

Further, as shown in FIG. 11B, even when the upper limit position of the weight bar 5 is set to the position where it abuts on the mounting frame 2, the weight bar extends from the interference mitigating portion 95 to the shielding plate portion 94 in the light shielding fin 9. Since the light-shielding fin 9 rotates smoothly as the 5 moves smoothly, its operability is not impaired. Further, as described with reference to FIG. 5B, a contact portion 97 is formed in the vicinity of the base of the shaft portion 91 provided on the light-shielding fin 9, and the contact portion 97 has the basic posture. When the light-shielding fin 9 rotates, the light-shielding fin 9 is restricted from rotating upward by coming into contact with the rotation restricting piece 20b. As a result, the light-shielding fins 9 do not come into contact with the bracket 6 and its mounting surface, and there is no possibility that the light-shielding fins 9 will be damaged by the collision of the weight bar 5. Therefore, the quality of the light-shielding fins 9 can be maintained without impairing the operability when the light-shielding fins 9 are attached to the attachment frame 2 of the roll screen 1.

Further, as shown in FIG. 11C, the basic posture is such that the longitudinal direction of the shielding plate portion 94 of the light-shielding fin 9 is substantially perpendicular to the front-rear direction of the mounting frame 2 (a state of hanging in the vertical direction). Is always maintained, by adjusting the position of the movement limiting member 12 attached on the operation code 7, the movement limiting member 12 abuts on the operation pulley 8 or the like to stop its rotation. The upper limit position of the weight bar 5 can be determined. As a result, the light-shielding fins 9 do not come into contact with the bracket 6 and its mounting surface, and there is no possibility that the light-shielding fins 9 will be damaged by the collision of the weight bar 5. Then, it is possible to maintain the basic posture in which the longitudinal direction of the shielding plate portion 94 of the light-shielding fin 9 is substantially perpendicular to the front-rear direction of the mounting frame 2 (a state of hanging in the vertical direction) at all times. The design and quality can be maintained.

Therefore, as shown in FIGS. 8 to 11, the light-shielding fin 9 of this embodiment can be attached to the attachment frame 2 of various roll screens 1, and its operability, quality, or designability. It does not have an adverse effect on.

(Modification example of attachment of light-shielding fin fabric)
In the light-shielding fin 9 of the above-described embodiment, as described with reference to FIGS. 6 and 7, the fabric 13 is attached to the upper end and the lower end of the front surface of the shielding plate portion 94, respectively, with a substantially hook cross-sectional shape. An example has been described in which the protruding pieces 96a and 96b are provided to form a gripping means for the protruding pieces 96a and the claw portion 99 to function as a cloth retainer. Further, even if the fabric 13 is displaced in the vertical direction due to the rotational operation of the light-shielding fins 9 due to the protruding pieces 96a and 96b, its function and design are not impaired.

However, when the fabric 13 is thin, or when the fabric 13 is displaced in the left-right direction due to the rotational operation of the light-shielding fins 9, the design property may be impaired. Therefore, as shown in FIG. 12, it is preferable to provide a narrowing pressure portion 100 with permanent deformation on the upper portion of the claw portion 99 at both left and right end portions of the shielding plate portion 94 of the light shielding fin 9. That is, as described with reference to FIGS. 6 and 7, the fabric 13 is attached to the light-shielding fins 9 and then crimped with a jig such as pliers to be permanently deformed to form the narrow pressure portion 100. .. By providing the narrow pressure portion 100 accompanied by permanent deformation in this way, it is possible to suppress the displacement of the fabric 13 in the left-right direction.

Alternatively, instead of providing the narrow pressure portion 100 with such permanent deformation, after the fabric 13 is attached to the light-shielding fins 9, the left and right end portions of the light-shielding fins 9 in the shield plate portion 94 as shown in FIG. 13A. A narrow pressure member 101 having a predetermined shape (U-shaped in this example) made of a rubber material or a synthetic resin is attached to the upper part of the claw portion 99, and the fabric 13 is narrowed as shown in FIG. 13 (a). By providing the narrow pressure member 101 that is detachable and elastically deformable in this way, it is possible to suppress the displacement of the fabric 13 in the left-right direction.

Alternatively, instead of providing such a narrowing pressure portion 100 or a narrowing pressure member 101, narrowing pressure portions 102 may be provided in advance at both left and right end portions of the shielding plate portion 94 of the light shielding fin 9. For example, as shown in FIG. 14A, a hole 102a having a narrow pressure portion 102 elastically deformable is provided at both left and right ends of the shielding plate portion 94, and the hole 102a is provided as shown in FIG. 14B. The narrow pressure portion 102 is elastically deformed to narrow the pressure of the dough 13 as shown in FIG. 14 (c). By providing the narrow pressure portion 102 that can be elastically deformed by external pressing in this way, it is possible to suppress the displacement of the fabric 13 in the left-right direction.

(Configuration example of light-shielding fins)
15 (a), (b), and (c) show configuration examples of typical light-shielding fins 9 in various shielding devices (including objects other than the roll screen 1). FIG. 15A shows the configuration of the light-shielding fin 9 of the above-described embodiment with reference to FIG. 3 and the like.

FIG. 15B shows an example in which the protrusion 96b is not provided as compared with the configuration shown in FIG. 15A, and other elements are the same. That is, in the example shown in FIG. 15B, since the protrusion 96b is not provided, the gripping means for the protrusion 96a and the claw portion 99 to function as the cloth holder is configured, and the cloth 13 is engaged and hung down. Although there is a possibility that the fabric 13 may flutter when the light-shielding fins 9 are rotated or the like, from another viewpoint, all of the light-shielding fins 9 of the above-described embodiment with reference to FIG. 3 and the like in FIG. 15 (a). The action / effect of the above can be obtained, and a modified example thereof can be applied.

Further, FIG. 15 (c) shows a typical example in the case where it is not necessary to rotate the light-shielding fin 9 as compared with the configuration shown in FIG. 15 (a). That is, the shaft portion 91 has a shape that can be fixed to the mounting frame 2, the shielding plate portion 94 is shortened, and the fabric 13 has a light-shielding function. Therefore, the above-mentioned elements according to the characteristic invention can be selectively adopted and modified according to the application.

Further, FIGS. 16A and 16B show perspective views of two structural examples relating to the attachment of the fabric 13 of the light-shielding fin 9 of one embodiment in the roll screen 1 of the present embodiment, respectively.

FIG. 16A shows a detailed view of the light-shielding fin 9 shown in FIG. 3 when a relatively thick cloth 13 is gripped by a protrusion 96a and a claw portion 99 configured as gripping means. There is. When such a relatively thick cloth 13 is gripped by the protrusion 96a and the claw portion 99, the protrusion 96a is in a state of being elastically deformed, and the protrusions with respect to AA'indicating the longitudinal direction of the shielding plate portion 94. BB'indicating the longitudinal direction of the piece 96a is non-parallel. When it is desired to further improve the point that the protruding piece 96a is non-parallel to the shielding plate portion 94 from the viewpoint of design, as a means for gripping the fabric 13 of the light-shielding fin 9, as shown in FIG. 16B. It can be a structure.

In the example shown in FIG. 16B, the claw portion 99 is not provided as a means for gripping the fabric 13 of the light-shielding fin 9, and is composed of the protrusion piece 96a and the narrowing pressure portion 100 shown in FIG. .. The protrusion 96a in this case is made of a rigid body that cannot be elastically deformed. The narrowing pressure portion 100 is formed by permanently deforming the fabric 13 at both left and right ends of the shielding plate portion 94 of the light-shielding fin 9 by attaching the fabric 13 to the light-shielding fin 9 and then caulking it with a jig such as pliers. .. As a result, even in the relatively thick fabric 13, BB'indicating the longitudinal direction of the protrusion 96a is substantially parallel to AA'indicating the longitudinal direction of the shielding plate portion 94. , The fabric 13 can be attached to the light-shielding fin 9.

Although the present invention has been described above with reference to examples of specific embodiments, the present invention is not limited to the examples of the above-described embodiments, and various modifications can be made without departing from the technical idea. In particular, the shape and structure of the shaft portion 91 of the light-shielding fin 9 and the method of locking are merely described as examples. For example, the shaft portion 91 of the light-shielding fin 9 may be formed by a round shaft or the like, or light-shielding. In the case of a roll screen, for example, the shaft portion 91 of the fin 9 may be supported not by the mounting frame 2 as a frame but by the support members 2a and 2b. Further, the position where the light-shielding fin 9 is locked to the mounting frame 2 by the shaft portion 91 is not limited to the front surface of the mounting frame 2, but may be the rear surface or the bottom surface of the mounting frame 2. Further, as a form in which the light-shielding fin 9 can be used, there are a horizontal blind, a raised curtain, a pleated screen, and the like, in addition to the roll screen.
