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.

(overall structure)
First, with reference to FIG.1 and FIG.2, the structure of the roll screen 1 as a shielding apparatus of one Embodiment by this invention is demonstrated. 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

2 a and 2 b are fixed to both ends of the mounting frame 2, and a shaft member 11 is fixed to the

support members

2 a and 2 b, and a fixed shaft ( The cylindrical winding pipe 3 is rotatably supported between the

support members

2a and 2b. 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 take-up pipe 3, and an endless operation cord 7 hung around the operation pulley 8 is suspended. In this example, the operation cord 7 is constituted by a ball chain, and the surface of the operation pulley 8 around which the ball chain is hung is configured so as to have irregularities having a shape suitable for the ball portion of the ball chain. . The winding pipe 3 can be rotated by operating the operation cord 7. The operation cord 7 formed of a ball chain has an endless shape with the cord ends connected by a cord connecting member 7a. The operation cord 7 may be formed in a string shape, and the surface of the operation pulley 8 around which the operation cord 7 is wound may have a highly frictional surface shape.

The winding pipe 3 is attached to one end of the screen 4 so as to wind the screen 4 or to support the suspension 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. Accordingly, 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 suspended from the outdoor side of the winding pipe 3 (see FIG. 2).

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. The movement restricting member 12 can be mounted on the operation cord 7 formed of a ball chain, and the movement restricting member 12 can be brought into contact with the operation pulley 8 or the like to stop its rotation. The upper limit position of the bar 5 may be determined.

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 device for preventing the weight of the screen 4 from falling down is housed on the right end side. 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 mounting frame 2, and the winding pipe 3 Light leakage from the gap generated between the mounting frame 2 and the mounting frame 2 is effectively shielded. As shown in FIG. 2, although details will be described later, 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. It is supported on the front side (front side) of the frame 2 so as to be rotatable within a predetermined range. Hereinafter, the light shielding fin 9 of one embodiment will be described in detail.

(Shading fin structure)
In FIG. 3, the structure of the light shielding fin 9 of one Example in the roll screen 1 of this embodiment is shown. FIG. 4 is an exploded perspective view showing a schematic configuration around the light shielding fin 9 of one example in the roll screen 1 of the present embodiment.

3 and 4 together, 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 high light shielding properties, aluminum, or the like, but may be a transparent or translucent synthetic resin when the fabric 13 is attached as in this example.

The width in the left-right direction of the light-shielding fin 9 is slightly shorter than the width in the left-right direction of the mounting frame 2. Even if it changes, it is locked so that it can rotate smoothly.

A bearing portion 20 having a substantially C-shaped cross section extending in the longitudinal direction 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 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

2a and 2b have the same shape, and as shown in FIG. 4, 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 is provided. . The notches 23 are provided so that the shaft portions 91 of the light shielding fins 9 can be slid from the left and right directions and inserted into the bearing portions 20 to be supported after the

support members

2a and 2b are fixed to the mounting frame 2. ing. Then, the light shielding fins 9 are slidable to be removable, and other than this slide is not removable, and even if an external force is applied to the light shielding fins 9, the light shielding fins 9 are not detached from the mounting frame 2.

Further, the

support members

2a and 2b have screw holes 21 for fixing the mounting frame 2 using mounting screws, and shaft members 11 having a fixed shaft (not shown) for rotatably supporting the winding pipe 3. Screw holes 22 for fixing (see FIG. 1) are provided at a plurality of locations. That is, even after the

support members

2a and 2b are fixed to the mounting frame 2 in a state in which the winding 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 and right directions to thereby obtain the bearing portion 20. It can be inserted and supported. For this reason, it is easy to attach the light shielding fins 9.

The side cover 10 is attached from the viewpoint of improving the design so that the mounting screws of the screw holes 21 and 22 of the

support members

2a and 2b cannot be visually recognized from the outside. There is also an effect of improving the functionality related to the rotation operation of the light shielding fins 9.

That is, the side cover 10 is provided with a wall having a height so as to regulate the positions of both ends 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. Part 10a 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. Thereby, regarding 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.

That is, the left and right end portions of the light shielding fin 9 abut against the wall portion 10a of the side cover 10 before abutting against the

support members

2a and 2b, so that the light shielding fin 9 is pivotably regulated. In other words, by restricting both end portions of the light shielding fin 9 in the left-right direction, the design property is ensured, and the adverse effect of rotation can be prevented while enhancing the light leakage effect. In this example, the width of the light-shielding fin 9 is configured to be slightly shorter than the width of the mounting frame 2 in the left-right direction, and the light-shielding fin 9 is configured to be turnable by the wall portion 10 a of the side cover 10. Although an example 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.

As shown in FIG. 3, a bearing portion 20 having a substantially C-shaped cross section extending in the longitudinal direction 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 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 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 backward. And the light shielding fin 9
In the state where the shaft portion 91 is locked to 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 shaft portion 91 is moved backward from the bearing portion 20. It is designed not to come off.

The light shielding fin 9 has, as a schematic configuration, a support plate portion 93 having a substantially C-shaped shaft portion 91 at the tip and protruding forward from the front side surface of the mounting frame 2 with 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 generates a collision force or contact sound due to interference with the screen 4 (or a weight bar 5 described later). It is formed of a double-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 bent shape in an approximately L shape, and a substantially C-shaped shaft portion 91 is formed at the tip thereof. The shaft portion 91 is a portion that is rotatably locked by the bending shaft 20f in the bearing portion 20. The tip of the shaft portion 91 is formed in a substantially bowl shape that is refracted at an acute angle, and is engaged with the bearing portion 20 in a state having a spatial margin so that the light shielding fins 9 are not easily detached 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 in this manner, an unpleasant interference sound due to the rotational interference between the light shielding fin 9 and the rotation restricting piece 20b ( In order to generate a contact sound), the shaft portion 91 is formed with a curved portion 92 that is changed in thickness and has a thickness in a rotation range.

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. Although the details will be described later, the abutting portion 97 is a portion that regulates the upward rotation of the light shielding fin 9 by abutting against the rotation restricting piece 20b.

Such a shape of the shaft portion 91 makes it difficult for the light shielding fin 9 to be detached from the bearing portion 20, and allows the light shielding fin 9 to be rotated while suppressing rattling and reducing the interference sound. ing. Thereby, the unpleasant interference sound (contact sound) resulting from the rotation interference of the contact part 97 and the rotation control piece 20b can be reduced so that it can be disregarded.

Further, a protrusion 98 is formed below the shaft 91 provided at the tip of the support plate 93, and the protrusion 98 protrudes from the support plate 93 along with the shaft 91. Although the details will be described later, the protrusion 98 is a portion that restricts the downward rotation of the light shielding fin 9 at a position in contact with the rotation restricting piece 20 a of the bearing portion 20 in the mounting frame 2. In particular, the tip of the protrusion 98 is formed in a shape having an uneven step as shown in the figure, and has a function of relaxing the contact sound and the collision force when coming into contact with the rotation restricting piece 20a. In addition, although the protrusion part 98 of this example is formed so that it may extend and protrude in the left-right direction of the support plate part 93, the form which protrudes partially in the left-right direction of the support plate part 93 may be sufficient.

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 weight bar 5 in the embodiment described later), the interference mitigation unit 95 warps away from the screen 4 (or weight bar 5) so as to relieve the contact sound and collision force. Has a shape.

Further, at the upper and lower ends of the front surface of the shielding plate portion 94,

projection pieces

96a and 96b projecting in a substantially cross-sectional shape are provided, respectively, and a recess for engaging the upper and lower ends of the fabric 13 is formed. In particular, a claw portion 99 is formed inside the projection piece 96a at the upper front end of the shielding plate portion 94, and the projection piece 96a and the claw portion 99 are configured as gripping means that function as a fabric presser. On the other hand, the projecting piece 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 that suppresses the fluttering and does not press-contact is formed. The description regarding attachment of the fabric 13 will be described later in detail.

(Lower and upper rotation restricting structure of light shielding fin)
FIGS. 5A and 5B are side views for explaining the operation of the light shielding fin 9 of one example in the roll screen 1 of the present embodiment. In particular, FIG. Regarding the side rotation restriction, FIG. 5B illustrates the upper side rotation restriction of the light shielding fin 9.

As shown in FIG. 5A, a protrusion 98 is formed below the shaft 91 provided at the tip of the support plate 93, and the protrusion 98 is aligned with the shaft 91 to support the plate. Projecting from the portion 93. The light shielding fins 9 are locked by the shaft portion 91 so as to be rotatable by the bending shaft 20 f of the bearing portion 20. The projecting portion 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 in contact with the rotation restricting piece 20 a of the bearing portion 20 in the mounting frame 2. At this time, as a basic posture of the light shielding fin 9, the longitudinal direction of the shielding plate portion 94 of the light shielding fin 9 is regulated so as to be substantially perpendicular to the front-rear direction of the mounting frame 2 (hanging in the vertical direction). . Thus, as a basic posture when the light shielding fin 9 is attached to the attachment frame 2 of the roll screen 1, 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 attachment frame 2 (in the vertical direction). The design is improved.

Further, as shown in FIG. 5B, a contact portion 97 is formed in the vicinity of the root of the shaft portion 91 provided in 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 or its mounting surface. Thus, the quality 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.

protrusions

96a and 96b projecting in a substantially cross-sectional shape at the front upper end and lower end of the shielding plate portion 94, respectively. A recess for engaging the upper and lower ends of the fabric 13 is formed. In particular, a claw portion 99 is formed inside the projection piece 96a at the upper front end of the shielding plate portion 94, and the projection piece 96a and the claw portion 99 are configured as gripping means that function as a fabric presser. On the other hand, the projecting piece 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 that suppresses the fluttering and does not press-contact is formed.

For example, when attaching the fabric 13 to the light shielding fin 9 according to the present embodiment, it is possible to insert the cloth 13 from the left and right ends of the light shielding fin 9 and attach it from the front side of the light shielding fin 9. It can be attached more easily. For example, as shown in FIG. 7, first, the upper end of the fabric 13 is engaged by the projection piece 96a and the claw portion 99 (see FIG. 7A), and then the lower end of the fabric 13 is formed into a recess formed by the projection piece 96b. Insert (see FIG. 7B). Thus, the fabric 13 can be easily attached to the light shielding fins 9. Moreover, since the light shielding fin 9 according to the present embodiment has a structure in which only the upper end of the cloth 13 is engaged, the cloth 13 does not bend and the design can be improved. And even if the fabric 13 is displaced in the vertical direction by the rotation operation of the light shielding fins 9 by the projecting

pieces

96a and 96b at the upper and lower ends of the front surface of the shielding plate portion 94, the function and the design are not impaired. .

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

(Operation of light shielding fins and versatility)
FIGS. 8A, 8 </ b> B, and 8 </ b> C are side views for individually explaining an operation example of the light shielding fin 9 of one example in the roll screen 1 of the present embodiment.

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

The length b of the shielding plate portion 94 is formed with a length that prevents light leakage caused by a gap between the mounting frame 2 and the winding pipe 3. The length a of the support plate portion 93 is set in a range that does not adversely affect the operation of the operation cord 7. Even if the operation cord 7 is operated so as to come into contact with the light shielding fins 9 of the present embodiment, the light shielding fins 9 are rotated so as not to cause an operation burden.

In addition, as shown in FIG. 8B, when the light shielding fin 9 of this embodiment is applied to a roll screen 1 having a relatively small maximum winding diameter S of the screen 4, the screen 4 and the light shielding fin 9 are provided. As a basic posture, there is no contact, and the light shielding fins 9 are shielded from light while maintaining the longitudinal direction of the shielding plate portion 94 substantially perpendicular to the front-rear direction of the mounting frame 2 (a state in which they are suspended in the vertical direction). The function can be retained.

On the other hand, as shown in FIG. 8C, when the light shielding fin 9 of this embodiment is applied to a roll screen 1 having a relatively large maximum winding diameter S of the screen 4, the screen 4 and the light shielding fin 9 are Even in the case of contact, the light shielding fin 9 can be rotated following the winding thickness of the screen 4, and the light shielding function can be maintained.

By the way, when the roll screen 1 is mounted on 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 faced to a wall surface (for example, a horizontal 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 attached to the wall surface W by using a fixing metal 61 (L-shaped metal in this example). The fixing bracket 61 fixes the bracket 6 through the first mounting hole 61a of the fixing bracket 61 using the mounting screw, and faces the wall surface W through the second mounting hole 61b of the fixing bracket 61. Thus, the mounting frame 2 of the roll screen 1 of this embodiment can be attached to the bracket 6 fixed to the wall surface W using the fixing bracket 61.

In particular, the fixing bracket 61 is configured so that the roll screen 1 of this embodiment is faced to the wall surface W with a certain gap between the roll screen 1 and the wall surface W. Thereby, it is possible to prevent the weight bar 5 and the wall surface W from colliding with each other when the screen 4 is wound up and the weight bar 5 reaches the upper limit position.

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 fins 9 of the present embodiment could not be attached to the roll screen 1. 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 faced 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 faced to the wall surface W, dust does not accumulate on the screen 4 being wound up by the light shielding fins 9, so that dust does not scatter during use. There is an effect.

Further, when the wound screen 4 is left unattended for a long period of time, uneven color deterioration of the screen 4 may occur due to direct external light. However, the roll screen 1 of the present embodiment having the light shielding fins 9 is provided on the wall surface. In the configuration faced to W, the light shielding fins 9 can surely prevent direct light on the screen 4 in the vicinity of the mounting frame 2 and improve the color resistance of the screen 4.

Further, in the roll screen shown in FIG. 9, since the light shielding fins 9 are pivotally supported with respect to the bearing portion 20 provided on the mounting frame 2, when the mounting frame 2 is fixed to the ceiling surface, when viewed from the front. The design property of can be improved.

Moreover, in the roll screen shown in FIG. 9, since the bearing portion 20 is formed continuously in the left-right direction of the mounting frame 2 as described with reference to FIG. However, it will not come off easily.

As a modification of the embodiment shown in FIG. 9, when the roll screen 1 is faced to the wall surface W using the fixing bracket 61 (in this example, an L-shaped bracket) via the bracket 6, the light shielding fin 9 is attached to the mounting frame. Instead of the configuration of supporting by the two bearing portions 20, the shape of the light shielding fin 9 can be modified and the light shielding fin 9 can be configured to be supported by the bracket 6 or the fixing bracket 61 (in this example, an L-shaped bracket). .

For example, FIGS. 10A and 10B show an example in which a roll screen 1 serving as a shielding device according to a modification of the present invention is faced to a wall surface. In FIGS. 10A and 10B, the same reference numerals are assigned to the same components as those in the above-described embodiment.

First, in the modification shown in FIG. 10A, instead of providing the substantially C-shaped shaft portion 91 at the tip of the support plate portion 93 in the shape of the light shielding fin 9 shown in FIG. It is assumed that the tip is bent in an L shape so as to have a portion 93a that goes upward and a portion 93b that goes backward through this portion 93a. Although it does not limit, the site | part 93a can be made into the plate-shaped body shielded over substantially the whole area of the left-right direction of the roll screen 1 from a design viewpoint. The part 93b is a part for fixing together with the bracket 6 using the fixing metal 61 (in this example, L-shaped metal), and is a plate-like piece that can be fixed by the fixing metal 61 or fixed by the fixing metal 61. It is possible to provide a plate-like body that is provided with notches that can be made and is substantially shielded over substantially the entire region of the roll screen 1 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. 3 is the same as the function of the light shielding fin 9 shown in FIG. 3 in that it is bent forward from the main body of the roll screen 1 and is connected to the shielding plate portion 9. The collision force and the contact sound due to the interference with the screen 4 (or a weight bar 5 described later) can be avoided or alleviated.

On the other hand, in the modification shown in FIG. 10 (b), a substantially C-shaped shaft portion 91 provided at the tip of the support plate portion 93 of the shape of the light shielding fin 9 shown in FIG. The suspension support member 62 for supporting the shaft portion 91 in a suspended manner is used.

The suspension support member 62 is bent in an L shape so as to have a portion 62a having a bearing portion 62c at its lower end and going upward, and a portion 62b going backward via 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 fins 9 shown in FIG. Also in this example, although it does not limit, the site | part 62a can be made into the plate-shaped body shielded over substantially the whole area of the left-right direction of the roll screen 1 from a design viewpoint. The part 62b is a part for fixing together with the bracket 6 using a fixing metal 61 (in this example, an L-shaped metal), and is a plate-like piece that can be fixed by the fixing metal 61 or fixed by the fixing metal 61. It is possible to provide a plate-like body that is provided with notches that can be made and is substantially shielded over substantially the entire region of the roll screen 1 in the left-right direction.

Then, the light shielding fin 9 of the modification shown in FIG. 10B is configured to be rotatable like 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.

As a further modification, when the light shielding fin 9 is supported by the bracket 6 or the fixing metal 61, the shape of the bracket 6 or the fixing metal 61 is changed to support the light shielding fin 9 so that it can rotate or cannot rotate. It can also be set as the structure to do. Therefore, the light shielding fin 9 is configured to directly support the mounting frame 2, the bracket 6, or the fixture 61, or by using a suspension support member 62 whose shape is appropriately adapted according to the application. It can be configured to be held indirectly.

Further, the light shielding fin 9 may be configured for the purpose of shielding air permeability in addition to being provided for the purpose of shielding external light, and in this case, it may be composed of a translucent material. In the present specification, when simply referred to as “fin”, it includes various support forms such as the shapes illustrated in FIG. 9A and FIGS. 10A and 10B, and is multipurpose such as light shielding purposes and wind shielding purposes. This means a shielding member.

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

11A, 11B, and 11C show a configuration when the light shielding fin 9 of the present embodiment is applied to the roll screen 1 of another embodiment.

In the example shown in FIG. 11A, the screen 4 is suspended from the winding pipe 3 on the light shielding fin 9 side of this embodiment, and the weight bar 5 is positioned between the light shielding fin 9 and the winding 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 it interferes with the weight bar 5. Does not cause a catch.

Further, as shown in FIG. 11B, even when the upper limit position of the weight bar 5 is set to a position where the weight bar 5 is in contact with the mounting frame 2, the weight bar extends from the interference mitigation portion 95 to the shielding plate portion 94 in the light shielding fin 9. Since 5 moves smoothly and the light-shielding fin 9 rotates, its operability is not impaired. Further, as described with reference to FIG. 5B, a contact portion 97 is formed near the base of the shaft portion 91 provided in the light shielding fin 9, and the contact portion 97 has the basic posture. When the light shielding fins 9 are rotated, they are in contact with the rotation restricting pieces 20b, thereby restricting the upward rotation of the light shielding fins 9. As a result, the light shielding fins 9 are not in contact with the bracket 6 or its mounting surface, and there is no possibility that the light shielding fins 9 are damaged by the collision of the weight bar 5. Therefore, the quality 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 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 in which it is suspended in the vertical direction). If the movement restriction member 12 attached on the operation cord 7 is adjusted, the movement restriction member 12 is brought into contact with 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 are not in contact with the bracket 6 or its mounting surface, and there is no possibility that the light shielding fins 9 are damaged by the collision of the weight bar 5. And the basic posture where the longitudinal direction of the shielding plate portion 94 of the light shielding fin 9 is almost perpendicular to the front-rear direction of the mounting frame 2 (a state in which the longitudinal direction hangs down) can be maintained. Designability 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 design properties are also provided. There is no negative impact on the product.

(Variation regarding attachment of light shielding fin fabric)
In the light-shielding fin 9 of the above-described embodiment, as described with reference to FIG. 6 and FIG. The example which comprises the

protrusion piece

96a, 96b which performs and makes the protrusion piece 96a and the nail | claw part 99 function as a fabric | pressor was demonstrated. Further, even when the dough 13 is displaced in the vertical direction by the rotation operation of the light shielding fins 9 by the projecting

pieces

96a and 96b, the function and design are not impaired.

However, when the cloth 13 is displaced in the left-right direction by the rotation operation of the light shielding fins 9, such as when the cloth 13 is thin, there is a possibility that the design property is impaired. Therefore, as shown in FIG. 12, it is preferable to provide a narrow 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, after the fabric 13 is attached to the light shielding fins 9, the narrow pressure portion 100 is formed by permanent deformation by caulking using a jig such as pliers. . By providing the narrow pressure part 100 with permanent deformation in this way, the lateral displacement of the fabric 13 can be suppressed.

Alternatively, instead of providing the narrow pressure portion 100 with such permanent deformation, after the fabric 13 is attached to the light shielding fin 9, both left and right end portions of the shielding plate portion 94 of the light shielding fin 9 as shown in FIG. Then, a narrow pressure member 101 having a predetermined shape (in this example, a U shape) made of a rubber material or a synthetic resin is mounted on the upper portion of the claw portion 99, and the fabric 13 is narrowed as shown in FIG. By providing the detachable and elastically deformable narrow pressure member 101 as described above, the lateral displacement of the fabric 13 can be suppressed.

Alternatively, instead of providing such a narrow pressure portion 100 and a narrow pressure member 101, narrow pressure portions 102 may be provided in the left and right ends of the shielding plate portion 94 of the light shielding fin 9 in advance. For example, as shown in FIG. 14A, a hole 102a having a narrow pressure portion 102 that can be elastically deformed is provided at both left and right ends of the shielding plate portion 94, and as shown in FIG. 14B, the hole 102a is provided. Then, the narrow pressure portion 102 is pressed and elastically deformed to narrow the fabric 13 as shown in FIG. Thus, by providing the narrow pressure portion 102 that can be elastically deformed by an external press, the lateral displacement of the fabric 13 can be suppressed.

(Example of configuration of light shielding fin)
15A, 15B, and 15C 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 embodiment described above with reference to FIG.

FIG. 15B shows an example in which the protruding piece 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. 15 (b), since the protruding piece 96b is not provided, a gripping means for causing the protruding piece 96a and the claw portion 99 to function as a fabric presser is configured, and the fabric 13 is engaged and suspended. Although there is a possibility that the fabric 13 flutters when the light shielding fins 9 are rotated, all other aspects of the light shielding fins 9 of the embodiment described above with reference to FIG. 3 in FIG. The operation and effect of the above can be obtained, and a modification thereof can be applied.

Further, FIG. 15C shows a typical example in the case where it is not necessary to rotate the light shielding fins 9 as compared with the configuration shown in FIG. 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 cloth 13 has a light shielding function. Therefore, the elements according to the above-described characteristic invention can be selectively adopted as appropriate and modified according to the application to be applied.

FIGS. 16A and 16B are perspective views of two structural examples related to attachment of the fabric 13 of the light shielding fin 9 of one example in the roll screen 1 of the present embodiment.

FIG. 16A shows a detailed view of the light shielding fin 9 shown in FIG. 3 when the relatively thick fabric 13 is gripped by the projecting piece 96a and the claw portion 99 configured as gripping means. Yes. When such a relatively thick fabric 13 is gripped by the projection piece 96a and the claw portion 99, the projection piece 96a is elastically deformed, and the projection Aa ′ indicating the longitudinal direction of the shielding plate portion 94 is protruded. 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 not parallel to the shielding plate portion 94 from the viewpoint of design, as shown in FIG. It can be a structure.

In the example shown in FIG. 16 (b), the claw part 99 is not provided as means for gripping the fabric 13 of the light shielding fin 9, and is constituted by the protruding piece 96a and the narrow pressure part 100 shown in FIG. . In this case, the protruding piece 96a is formed of a rigid body that cannot be elastically deformed. The narrow pressure portion 100 is formed by permanent deformation by attaching the cloth 13 to the light shielding fins 9 at both left and right ends of the shielding plate portion 94 of the light shielding fins 9 and then caulking them with a jig such as pliers. . As a result, even with a relatively thick fabric 13, BB ′ indicating the longitudinal direction of the protruding piece 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 fins 9.

As described above, the present invention has been described with reference to examples of specific embodiments, but 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 thereof. In particular, the shape and structure of the shaft portion 91 of the light shielding fin 9 and the method of locking are only 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. If the axial part 91 of the fin 9 is a roll screen, for example, it can also be set as the structure supported not on the attachment frame 2 as a frame but on the

support members

2a and 2b. Further, the position where the shading 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. In addition to the roll screen, the light-shielding fins 9 can be used in the form of horizontal blinds, raised curtains, pleated screens, and the like.

According to the present invention, it is possible to configure a shielding device having a light-shielding fin that improves design and operability and allows a predetermined fabric to be easily attached. Useful for.
