Description

Screening arrangement and roller shutter

Technical Field

The present invention relates to a shielding device and a roller shutter capable of opening or closing a shielding member.

Background

Conventionally, as a shielding device capable of opening and closing a shielding member, there are a roll blind, a horizontal blind, a roll-up type curtain, a pleated curtain, and the like.

For example, the roller blind is constituted by: the winding shaft is supported by the frame, the upper end part of the curtain cloth is installed on the winding shaft and hangs down, and the counterweight part is arranged on the lower end part of the shielding part (curtain cloth), so that the curtain cloth is wound or unwound by the winding shaft, and the indoor lighting amount can be adjusted.

Therefore, there is disclosed a method of providing a gap preventing member for preventing a gap between a winding shaft for winding a fabric and a lower surface of a frame for supporting the winding shaft, in which a base end edge of the gap preventing member is rotatably supported on the lower surface of the frame and the gap preventing member hangs down on a circumferential surface of a winding pipe (see, for example, patent document 1).

Detailed Description

Hereinafter, a rolling screen 1 as a shielding device according to an embodiment of the present invention will be described with reference to the drawings. In the description of the present application, in the front view of the roll screen 1 shown in fig. 1, the upper side and the lower side in the drawing are defined as the upper side (or upper side) and the lower side (or lower side), respectively, with respect to the hanging direction of the screen 4, and the left side in the drawing is defined as the left side of the screen 1 and the right side in the drawing is defined as the right side of the screen 1. In the following description, the side visible in the front view of the roll screen 1 shown in fig. 1 is referred to as the front side (or indoor side) and the opposite side is referred to as the rear side (or outdoor side), and when the roll screen 1 is referred to as the front-rear direction, the direction is the direction perpendicular to the plane of the front view of fig. 1.

(integral constitution)

First, a configuration of a rolling screen 1 as a shielding device according to an embodiment of the present invention will be described with reference to fig. 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 a mounting frame 2, a shaft member 11 is fixed to the

support members

2a and 2b, and a cylindrical winding tube 3 is rotatably supported between the

support members

2a and 2b by a fixed shaft (not shown) extending from the shaft member 11. The mounting frame 2 is fixed to a mounting surface by a bracket 6. The

support members

2a and 2b are housed in the side cover 10, and the appearance and performance of the light-shielding sheet 9 with respect to the rotational operation thereof are improved, as will be described later.

An operation pulley 8 is provided at the right end of the winding pipe 3, and an annular operation rope 7 is hung down while being wound around the operation pulley 8. In this example, the operation cord 7 is formed of a ball chain, and the surface of the operation pulley 8 around which the ball chain is wound is formed to have an uneven shape corresponding to the ball portion of the ball chain. The windup tube 3 can be rotated by operating the operation cord 7. The operation cord 7 formed of a bead chain is formed in a ring shape by connecting the cord ends by a cord connecting member 7 a. Further, 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 be formed in a high-friction surface shape.

One end of the curtain cloth 4 is mounted on the winding pipe 3, and the curtain cloth 4 is suspended and supported on the winding pipe 3 in a manner of being capable of being wound or unwound. The other end of the curtain cloth 4 is attached to a weight lever 5 functioning as a weight member. Therefore, the curtain 4 is tensioned by the weight of the weight lever 5. In the example of the present embodiment, the curtain cloth 4 hangs down from the outdoor side of the winding pipe 3 (see fig. 2).

Then, when the winding tube 3 is rotated in the fabric winding direction by operating the operation cord 7, the weight lever 5 is raised, and when the winding tube 3 is rotated in the fabric unwinding direction, the weight lever 5 is lowered. In addition, the following configuration may be adopted: the movement restricting member 12 may be attached to the operation cord 7 formed of a ball chain, and the movement restricting member 12 may be brought into contact with the operation pulley 8 or the like to stop the rotation thereof, thereby determining the upper limit position of the weight lever 5.

Further, a barrel for reducing an operation force at the time of winding the fabric 4 is housed in a left end side of the winding pipe 3, and a brake device or the like (not shown) for preventing the fabric 4 from lowering by its own weight is housed in a right end side.

Here, in the roll screen 1 according to the present invention, the light shielding sheet 9 having a structure in which the predetermined cloth 13 can be easily attached is attached to the front side (front surface side) of the mounting frame 2, thereby effectively preventing light from leaking from the gap between the winding tube 3 and the mounting frame 2. As shown in fig. 2, the shaft portion 91 of the shade 9 is engaged with a bearing portion 20 provided on the front surface side of the mount frame 2, and thereby the shade 9 is supported on the front side (front surface side) of the mount frame 2 so as to be rotatable within a predetermined range, which will be described in detail later. The light-shielding sheet 9 of one embodiment will be described in detail below.

(constitution of light-shielding sheet)

Fig. 3 shows a structure of the shade sheet 9 in an example of the roll screen 1 of the present embodiment. Fig. 4 is an exploded perspective view showing a schematic configuration around the shade sheet 9 in one example of the roll screen 1 of the present embodiment.

Referring to fig. 3 and 4 together, the light-shielding sheet 9 has a substantially L-shaped cross section as a whole, and is rotatably locked to the front side (front side) of the mounting frame 2. The light-shielding sheet 9 is preferably formed of a synthetic resin having high light-shielding properties, aluminum, or the like, but a transparent or translucent synthetic resin may be used when the cloth 13 is attached as in this example.

Further, the width of the light-shielding sheet 9 in the left-right direction is slightly smaller than the width of the mounting frame 2 in the left-right direction, and even if the width in the left-right direction changes due to thermal expansion or the like when the light-shielding sheet 9 is formed of synthetic resin, for example, the light-shielding sheet can be locked so as to be smoothly rotatable.

A bearing portion 20 having a substantially C-shaped cross section is formed on the front lower side of the mount 2 so as to extend in the longitudinal direction thereof. The shaft 91 of the shade 9 is engaged with the bearing 20, thereby rotatably supporting the shade 9 on the front side of the mount frame 2.

Support members

2a and 2b are attached to both longitudinal ends of the mount 2.

The

support members

2a and 2b have the same configuration, and as shown in fig. 4, the

support members

2a and 2b are provided with notches 23 having a size approximately corresponding to the approximately C-shaped cross-sectional shape of the bearing portion 20 of the mount 2. The cutout 23 is provided to allow the shaft 91 of the shade 9 to be slidably inserted from the left-right direction into the bearing 20 and supported after the

support members

2a and 2b are fixed to the mount 2. The shade sheet 9 can be removed by sliding, and is not removed except for the sliding, so that the shade sheet 9 does not fall off the mount 2 even if an external force is applied to the shade sheet 9.

In addition, screw holes 21 and screw holes 22 are provided at a plurality of positions of the

support members

2a and 2b, wherein the screw holes 21 are used for fixing the mounting frame 2 with mounting screws, and the screw holes 22 are used for fixing the shaft member 11 (refer to fig. 1) having a fixed shaft (not shown) rotatably supporting the winding tube 3. That is, even after the

support members

2a and 2b are fixed to the mount frame 2 in a state where the windup tube 3 is supported by the

support members

2a and 2b, the shaft portion 91 of the shade sheet 9 can be inserted and supported in the bearing portion 20 by sliding in the left-right direction. Therefore, the mounting of the light-shielding sheet 9 becomes easy.

The side cover 10 is attached from the viewpoint of making the mounting screws in the screw holes 21 and 22 of the

support members

2a and 2b invisible from the outside and improving the appearance thereof, but the side cover 10 also has the function of improving the performance relating to the turning operation of the shade sheet 9.

That is, the side cover 10 is formed with the wall portion 10a, and the wall portion 10a has a height for regulating both end positions of the shade 9 in the left-right direction within the rotation range of the shade 9, so that the shade 9 can be smoothly rotated. The wall 10a has a height sufficient to accommodate the thickness of the

support members

2a, 2 b. The side cover 10 is made of synthetic resin and can be attached by sandwiching the

support members

2a and 2b made of metal material, and the wall portion 10a is formed with a claw portion 10b projecting inward so as to sandwich the

support members

2a and 2 b. Thus, the wall portion 10a has a height such that the claw portion 10b and the notch 23 do not interfere with the rotational operation of the shade 9 with respect to the rotational operation of the shade 9.

That is, the left and right end portions of the light-shielding sheet 9 abut against the wall portions 10a of the side covers 10 before abutting against the

support members

2a and 2b, and the locking position of the light-shielding sheet 9 is restricted so that the light-shielding sheet 9 can rotate, that is, both end portions in the left-right direction of the light-shielding sheet 9 are restricted, whereby the appearance can be ensured, the light leakage prevention effect can be improved, and the rotation can be prevented from being hindered. In this example, although the lateral width of the light-shielding sheet 9 is slightly smaller than the lateral width of the mounting frame 2 and the light-shielding sheet 9 is restricted in a rotatable state by the wall portion 10a of the side cover 10, the

support members

2a and 2b and the side cover 10 may be avoided by the shape of the light-shielding sheet 9.

As shown in fig. 3, a bearing portion 20 having a substantially C-shaped cross section is formed on the front lower side of the mount 2 so as to extend in the longitudinal direction thereof. More specifically, the bearing portion 20 is formed with a bent shaft 20f at the front end of a rotation restricting piece 20a extending upward from the bottom of the mount 2, and is capable of supporting the shaft portion 91 of the shade 9. The rotation restricting piece 20a has a function of restricting the downward rotation of the light shielding piece 9. Further, a rotation restricting piece 20b for restricting the upward rotation of the shade 9 is formed on the front surface of the mount 2 above the bearing portion 20. In the illustrated example, the rotation restricting piece 20a is formed in a substantially C-shape protruding forward from the main body front surface of the mount 2, and the rotation restricting piece 20b is formed in a substantially plate shape protruding forward.

In a state where the shaft portion 91 of the shade 9 is locked in the bearing portion 20, the rotation of the shade 9 in the vertical direction is restricted, and the shade 9 does not fall off from the bearing portion 20 in the front direction regardless of the rotation of the shade 9.

The light-shielding sheet 9 is roughly configured as follows: the shade sheet 9 is formed of a member (either a single member or a composite member) having a multi-curved surface shape so as to prevent or mitigate the generation of collision force or contact sound due to interference with the curtain fabric 4 (or a weight lever 5 described later) by having a support plate portion 93 and a shield plate portion 94, and having an overall L-shaped cross-sectional shape, wherein the support plate portion 93 has a substantially C-shaped shaft portion 91 at the front end thereof, and is bent forward by a protruding length a from the front side surface of the mount 2, and the shield plate portion 94 extends downward by a length b from the support plate portion 93.

More specifically, the support plate 93 is bent into a substantially L-shape, and a substantially C-shaped shaft 91 is formed at the tip thereof. Shaft 91 is rotatably locked by bending shaft 20f in bearing 20. By forming the tip of the shaft 91 in a substantially hook shape bent at an acute angle and engaging the bearing 20 with a space, the shade 9 is less likely to fall off from the bearing 20, and the degree of freedom of rotation of the shade 9 is increased.

On the other hand, when the shaft portion 91 of the shade 9 is locked in the bearing portion 20 in such a manner that the degree of freedom of rotation is increased, an unpleasant noise (contact noise) is generated due to the interference of the rotation of the shade 9 and the rotation restricting piece 20b, and therefore, the shaft portion 91 is formed with a bent portion 92, and the bent portion 92 is formed by changing the thickness of the shaft portion 91, and the thickness thereof is within the range of rotation.

Further, an abutting portion 97 is formed near the root portion of the shaft portion 91 provided at the tip of the support plate portion 93. The abutting portion 97 abuts against the rotation restricting piece 20b to restrict the upward rotation of the light shielding piece 9, which will be described in detail later.

By forming the shaft portion 91 in the above shape, the light-shielding sheet 9 is less likely to fall off from the bearing portion 20, rattling is suppressed, noise is reduced, and the light-shielding sheet 9 is allowed to rotate. This makes it possible to reduce, to a negligible extent, an unpleasant disturbing sound (contact sound) caused by the interference of the abutting portion 97 with the rotation of the rotation restricting piece 20 b.

Further, a projection 98 is formed below the shaft portion 91 provided at the front end of the support plate portion 93, and the projection 98 projects from the support plate portion 93 in parallel with the shaft portion 91. The protrusion 98 is a portion that restricts downward rotation of the shade 9 at a position where it abuts against the rotation restricting piece 20a of the bearing portion 20 in the mount 2, which will be described later in detail. In particular, the tip of the projection 98 is formed in an uneven shape as shown in the drawing, and functions to alleviate contact noise and collision force when the rotation restricting piece 20a comes into contact therewith. In addition, although the projecting portion 98 in this example is formed so as to project over the entire lateral range of the support plate portion 93, it may be formed so as to project only at a partial position in the lateral direction of the support plate portion 93.

Further, a disturbance alleviating portion 95 having a curved surface shape is formed at the lower end of the shielding plate portion 94 extending downward from the support plate portion 93. The disturbance alleviating portion 95 has a shape that warps in a direction away from the fabric 4 (or the weight lever 5), and can alleviate the contact sound and the collision force even when the disturbance alleviating portion comes into contact with the fabric 4 (or the weight lever 5 in the embodiment described later).

Further, protruding

pieces

96a and 96b protruding in a substantially hook-shaped cross section are provided on the front upper end and the front lower end 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, claw portions 99 are formed on the upper front end of the shielding plate portion 94 on the inner side of the protruding pieces 96a, and the protruding pieces 96a and the claw portions 99 constitute a clamping mechanism that functions as a cloth presser. On the other hand, the protruding piece 96b at the front lower end of the shielding plate 94 is a portion for suppressing the wobbling of the cloth 13, and forms a concave portion which suppresses the wobbling of the cloth 13 but does not press the cloth 13. The attachment of the cloth 13 will be described in detail later.

(lower and upper rotation restricting structure of shading sheet)

Fig. 5 (a) and (b) are side views explaining the operation of the shade 9 in one example of the roll screen 1 of the present embodiment, and particularly fig. 5 (a) shows the lower rotation restriction of the shade 9, and fig. 5 (b) shows the upper rotation restriction of the shade 9.

As shown in fig. 5 (a), a projection 98 is formed below the shaft portion 91 provided at the front end of the support plate portion 93, and the projection 98 projects from the support plate portion 93 in parallel with the shaft portion 91. The shaft 91 of the shade 9 is rotatably locked to the bent shaft 20f of the bearing 20. The protrusion 98 provided on the shade 9 has a function of restricting the downward rotation of the shade 9 at a position abutting against the rotation restricting piece 20a of the bearing portion 20 of the mount 2. At this time, the basic posture of the light-shielding sheet 9 is limited to: the longitudinal direction of the shield plate portion 94 of the light shield sheet 9 is substantially perpendicular to the front-rear direction of the mount 2 (vertically hanging). Thus, the longitudinal direction of the shield plate portion 94 of the shade 9 is substantially perpendicular to the front-rear direction of the mounting frame 2 (hangs down in the vertical direction) as a basic posture when the shade 9 is mounted on the mounting frame 2 of the roll screen 1, and thus the appearance thereof is improved.

As shown in fig. 5 (b), an abutting portion 97 is formed near the root of the shaft portion 91 provided in the light-shielding sheet 9. The abutting portion 97 abuts against the rotation restricting piece 20b when the shade 9 starts to rotate from the basic posture, and restricts the upward rotation of the shade 9. Thus, the light-shielding sheet 9 does not abut against the bracket 6 or the mounting surface thereof. This prevents the workability of attaching the shade sheet 9 to the mounting frame 2 of the roller blind 1 from being impaired, and enables the quality thereof to be maintained.

(method of mounting Fabric on shade)

Fig. 6 (a) is a side view showing a structure relating to attachment of the cloth 13 to the shade 9 in one example of the roll screen 1 of the present embodiment, and fig. 6 (b) shows a comparative example thereof. Fig. 7 (a), (b), and (c) show an example of a method of attaching the cloth 13 to the shade sheet 9 in one example of the roll screen 1 according to the present embodiment.

First, as shown in fig. 6 (a), the light-shielding sheet 9 according to the present embodiment is provided with protruding

pieces

96a and 96b protruding in a substantially hook-shaped cross section at the front upper end and the front lower end of the shielding plate portion 94, respectively, and forms recesses for engaging the upper end and the lower end of the cloth 13. In particular, claw portions 99 are formed on the upper front end of the shielding plate portion 94 on the inner side of the protruding pieces 96a, and the protruding pieces 96a and the claw portions 99 constitute a clamping mechanism that functions as a cloth presser. On the other hand, the protruding piece 96b at the front lower end of the shielding plate 94 is a portion for suppressing the wobbling of the cloth 13, and forms a concave portion which suppresses the wobbling of the cloth 13 but does not press the cloth 13.

For example, when the cloth 13 is attached to the shade sheet 9 according to the present embodiment, the cloth can be inserted from the left and right end portions of the shade sheet 9, but the attachment from the front side of the shade sheet 9 is simpler. For example, as shown in fig. 7, the upper end of the cloth 13 is first fixed by the projection piece 96a and the claw 99 (see fig. 7 a), and then the lower end of the cloth 13 is inserted into the recess formed by the projection piece 96b (see fig. 7 b). This makes it possible to easily attach the cloth 13 to the shade 9. In addition, since the shade sheet 9 according to the present embodiment is configured to fix only the upper end of the cloth 13, the cloth 13 is not bent, and the appearance thereof can be improved. Further, even if the cloth 13 is displaced in the vertical direction by the rotating operation of the shade 9 due to the protruding

pieces

96a and 96b at the front upper and lower ends of the shade plate 94, the function and the appearance thereof are not impaired.

Further, when the cloth 13 is attached to the shade 9 by bonding or the like, or when the clamping mechanism functioning as a cloth presser is configured by providing the claw portion 99 also at the front lower end of the shield plate portion 94 as shown in fig. 6 (b), the cloth 13 is bent, and the work load at the time of attachment is increased in order to eliminate the bending. Therefore, it is preferable that only the upper end of the cloth 13 is fixed as in the light-shielding sheet 9 according to the present embodiment, and the cloth 13 is not bent, thereby facilitating the attachment.

(operation and multipurpose adaptability of shading sheet)

Fig. 8 (a), (b), and (c) are side views for explaining an example of the operation of the shade sheet 9 in one example of the roll screen 1 of the present embodiment.

As shown in fig. 8 (a), the light shielding sheet 9 of the present embodiment has a support plate portion 93 and a shielding plate portion 94, and has a substantially L-shaped cross section as a whole, in which the support plate portion 93 is bent from the front side surface of the mounting bracket 2 by a protruding length a toward the front, and the shielding plate portion 94 extends downward by a length b from the support plate portion 93.

The length b of the shielding plate portion 94 is formed to a length that can prevent light leakage from the gap between the mounting bracket 2 and the winding tube 3. The length a of the support plate 93 is set within a range that does not adversely affect the operation of the operation cord 7. Even when the operation is performed in a state where the operation cord 7 is in contact with the shade 9 of the present embodiment, the shade 9 is rotated, and thus no operation load is generated.

In addition, as shown in fig. 8 (b), when the shade 9 of the present embodiment is applied to the roller blind 1 in which the maximum winding diameter S of the shade 4 is small, the shade 4 and the shade 9 do not contact each other, and the shade function can be maintained while maintaining a state in which the longitudinal direction of the shield plate portion 94 of the shade 9 is substantially perpendicular to the front-rear direction of the mount frame 2 (a state in which the shade is vertically suspended), as the basic posture thereof.

On the other hand, as shown in fig. 8 (c), when the shade sheet 9 of the present embodiment is applied to the roller blind 1 having the large maximum winding diameter S of the shade 4, even when the shade 4 comes into contact with the shade sheet 9, the shade sheet 9 can be rotated in accordance with the winding amount of the shade 4, and the light-shielding function thereof can be maintained.

However, in the case where the roll screen 1 is wall-mounted on a wall surface according to the related art, there is a problem that the shade sheet 9 cannot be mounted on the roll screen 1.

Fig. 9 (a) shows an example of the wall-mounting of the roll screen 1 of the present embodiment to a wall surface (e.g., a vertical wall surface) W, and (b) shows a comparative example thereof.

As shown in fig. 9 (a), the roll screen 1 of the present embodiment having the shade sheet 9 can be wall-mounted on a wall surface W using a fixing member 61 (an L-shaped member in this example). The fixing member 61 fixes the bracket 6 by a mounting screw through the first mounting hole 61a of the fixing member 61, and is wall-mounted on the wall surface W through the second mounting hole 61b of the fixing member 61. The mounting frame 2 of the roll screen 1 of the present embodiment can be mounted to the bracket 6 thus fixed to the wall surface W with the fixing member 61.

In particular, the fixing member 61 is constituted by: the roller blind 1 of the present embodiment is mounted on the wall surface W with a certain gap between the roller blind 1 and the wall surface W. Thus, when the curtain fabric 4 is wound and the weight lever 5 reaches the upper limit position, the weight lever 5 can be prevented from colliding with the wall surface W.

That is, as shown in fig. 9 (b), in the case of the wall-mounted rolling blind 1 according to the related art, although the shade sheet 9 of the present embodiment cannot be mounted on the rolling blind 1, the rolling blind 1 of the present embodiment having the shade sheet 9 can be wall-mounted on the wall surface W by using the fixing member 61 (L-shaped fitting in the present embodiment).

In addition, in the structure in which the roll screen 1 of the present embodiment having the shade 9 is mounted on the wall surface W, since the shade 9 prevents dust from accumulating on the wound cord fabric 4, there is an effect that dust does not scatter during use.

In addition, although the color of the cord 4 is discolored or uneven in color due to the direct incidence of external light when the cord 4 is left standing for a long period of time after being wound, in the configuration in which the roll screen 1 of the present embodiment having the shade 9 is attached to the wall surface W, the shade 9 can reliably prevent the light from being directly incident on the cord 4 in the vicinity of the mount frame 2, and the color resistance of the cord 4 can be improved.

In the roller blind shown in fig. 9, since the shade sheet 9 is supported by the bearing portion 20 provided in the mount bracket 2, the appearance in front view can be improved as in the case of fixing the mount bracket 2 to the ceiling.

In the roll screen shown in fig. 9, since the bearing portion 20 is continuously formed along the entire left-right direction of the mount frame 2 as described with reference to fig. 4, it is not easily detached even if external disturbance or the like is applied.

As a modification of the embodiment shown in fig. 9, the following configuration may be adopted: when the roll screen 1 is wall-mounted on the wall W via the bracket 6 using the fixing member 61 (L-shaped member in this example), the shape of the shade 9 is changed so that the shade 9 is supported by the bracket 6 or the fixing member 61 (L-shaped member in this example) instead of supporting the shade 9 by the bearing portion 20 of the mount 2.

For example, fig. 10 (a) and (b) show an example in which a rolling blind 1 as a shielding device according to a modification of the present invention is wall-mounted on a wall surface. In fig. 10, (a) and (b) have the same reference numerals as those of the above-described embodiment.

First, in the modification shown in fig. 10 (a), instead of providing the substantially C-shaped shaft portion 91 at the front end of the support plate portion 93 in the shape of the shade sheet 9 shown in fig. 3, the front end of the support plate portion 93 is formed into an L-shaped curved shape having a portion 93a extending upward and a member 93b extending rearward after passing through the portion 93 a. The portion 93a may be formed into a plate-like body that is shielded substantially over the entire region of the roll screen 1 in the left-right direction from the viewpoint of appearance, but is not limited thereto. The member 93b is a portion fixed together with the bracket 6 by the fixing member 61 (L-shaped fitting in this example), and may be a plate-shaped piece that can be fixed by the fixing member 61, or a plate-shaped body that can be fixed by the fixing member 61, has a cutout, and is shielded over substantially the entire region in the left-right direction of the roll screen 1.

The shade 9 of the modification shown in fig. 10 (a) differs from the shade 9 shown in fig. 3 in that it is configured to be non-rotatable, but the support plate portion 93 shown in fig. 10 (a) has the same function as the shade 9 shown in fig. 3 in that it is curved and protruded forward from the main body of the roll blind 1 and is continuous with the shield plate portion 94, thereby allowing the curtain 4 to be wound by a certain amount and avoiding or mitigating collision force and contact noise caused by interference with the curtain 4 (or the weight lever 5 described later).

On the other hand, the modification shown in fig. 10 (b) is formed as follows: the shape of the substantially C-shaped shaft portion 91 provided at the front end of the support plate portion 93 in the shape of the light-shielding sheet 9 shown in fig. 3 is changed to the shape shown in the drawing, and the suspension support member 62 for suspending and supporting the shaft portion 91 is used.

The suspension support member 62 has a portion 62a extending upward and having a bearing portion 62c at a lower end thereof, and a portion 62b extending rearward after passing through the portion 62a, and is bent in an L shape. The bearing portion 62c has the same function as the bearing portion 20 provided on the front side of the mount 2 for supporting the shade 9 shown in fig. 3. In this example, the portion 62a may be formed as a plate-like body that is shielded substantially over the entire region in the left-right direction of the roll screen 1 from the viewpoint of appearance, but is not limited thereto. The member 62b is a portion fixed together with the bracket 6 by the fixing member 61 (L-shaped fitting in this example), and may be a plate-shaped piece that can be fixed by the fixing member 61 or a plate-shaped body that can be fixed by the fixing member 61 and has a cutout, and is shielded over substantially the entire region in the left-right direction of the roll screen 1.

The light-shielding sheet 9 of the modification shown in fig. 10 (b) is configured to be rotatable in the same manner as the light-shielding sheet 9 shown in fig. 3, and includes all the functions of the light-shielding sheet 9 shown in fig. 3.

As a further modification, the following may be adopted: when the shade 9 is supported by the bracket 6 or the mount 61, the shape of the bracket 6 or the mount 61 is changed to rotatably or non-rotatably support the shade 9. Therefore, the light-shielding sheet 9 may be configured to: directly supported on the mounting frame 2, the bracket 6 or the fixing member 61, or indirectly supported by using the suspension support member 62 with a shape appropriately changed according to the purpose.

In addition, since the light-shielding sheet 9 may be formed for the purpose of shielding air permeability, in addition to the light-shielding sheet 9 provided for the purpose of shielding external light, in this case, a light-transmitting material may be used, and therefore, in the present specification, when only the "fin" is referred to, various support forms such as shapes illustrated in fig. 9 (a) and fig. 10 (a) and (b) are included, and the shield member is referred to as a multiple-purpose shield member for the purpose of shielding light, shielding wind, and the like.

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

Fig. 11 (a), (b), and (c) show structures in which the shade sheet 9 of the present embodiment is applied to the roller blind 1 of another embodiment.

The example shown in fig. 11 (a) is an example in which the shade 4 hangs down from the winding tube 3 on the shade 9 side of the present embodiment, and the weight lever 5 is positioned between the shade 9 and the winding tube 3. In this case, the light-shielding sheet 9 of the present embodiment has the interference alleviating portion 95 formed in a curved shape at the lower end of the shielding plate portion 94 extending downward from the support plate portion 93, and therefore does not interfere with the weight lever 5 and get caught.

Further, as shown in fig. 11 (b), even when the upper limit position of the weight lever 5 is set at the position abutting on the mount frame 2, the weight lever 5 smoothly moves from the interference alleviating portion 95 of the light-shielding sheet 9 to the shield plate portion 94 to rotate the light-shielding sheet 9, and therefore, the operability thereof is not impaired. As described with reference to fig. 5 (b), an abutting portion 97 is formed near the root of the shaft portion 91 provided in the light-shielding plate 9, and the abutting portion 97 abuts against the rotation restricting piece 20b when the light-shielding plate 9 is rotated from the basic posture, thereby restricting the upward rotation of the light-shielding plate 9. Thus, the light-shielding sheet 9 does not abut against the bracket 6 or the mounting surface thereof, and the light-shielding sheet 9 is not damaged by the collision of the weight lever 5. Therefore, the workability of attaching the shade sheet 9 to the mounting frame 2 of the roller blind 1 is not impaired, and the quality thereof can be maintained.

As shown in fig. 11 (c), when the basic posture in which the longitudinal direction of the shield plate portion 94 of the shade 9 is substantially perpendicular to the front-rear direction of the mount frame 2 (a state in which the shade is suspended in the vertical direction) is to be maintained at all times, the upper limit position of the weight lever 5 can be fixed by adjusting the position of the movement restricting member 12 attached to the operation cord 7, causing the movement restricting member 12 to abut against the operation pulley 8 or the like and stop the rotation thereof. Thus, the light-shielding sheet 9 does not come into contact with the bracket 6 or the mounting surface thereof, and the light-shielding sheet 9 is not damaged by the collision of the weight lever 5. Further, the basic posture of the longitudinal direction of the shield plate portion 94 of the shade sheet 9 in a state substantially perpendicular to the front-rear direction of the mount 2 (a state of being suspended in the vertical direction) can be always maintained, and the appearance and quality thereof can be maintained.

Therefore, as shown in fig. 8 to 11, the shade sheet 9 of the present embodiment can be mounted on the mounting frame 2 of various roller blinds 1 without adversely affecting the operability and quality, or the aesthetic appearance thereof.

(modification of attachment of cloth to shade sheet)

In the light-shielding sheet 9 of the above-described embodiment, as for the attachment of the cloth 13, as described with reference to fig. 6 and 7, an example has been described in which protruding

pieces

96a and 96b protruding in a substantially hook-shaped cross section are provided at the front upper end and the front lower end of the shielding plate portion 94, respectively, and a clamping mechanism functioning as a cloth presser is configured by the protruding pieces 96a and the claw portions 99. Further, even when the cloth 13 is displaced in the vertical direction by the turning operation of the shade 9 by the

projection pieces

96a and 96b, the function and the appearance thereof are not impaired.

However, if the cloth 13 is displaced in the left-right direction due to the turning operation of the shade 9, for example, if the cloth 13 is thin, the appearance may be impaired. Therefore, as shown in fig. 12, it is preferable to provide a clamping portion 100 associated 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 sheet 9. That is, as described with reference to fig. 6 and 7, after the cloth 13 is attached to the light-shielding sheet 9, the cloth is caulked and permanently deformed by using a jig such as pliers, and the compression portion 100 is formed. By providing the nip portion 100 with permanent deformation in this manner, the fabric 13 can be prevented from being displaced in the left-right direction.

Alternatively, instead of providing the above-described compression portion 100 involving permanent deformation, after the cloth 13 is attached to the shade sheet 9, as shown in fig. 13 (a), compression members 101 of a predetermined shape (in the present example, a shape of "コ") made of a rubber material or a synthetic resin are attached to the upper portions of the claw portions 99 at both left and right end portions of the shade plate portion 94 of the shade sheet 9, thereby compressing the cloth 13 as shown in fig. 13 (b). By providing the detachable and elastically deformable clamping member 101 in this manner, the fabric 13 can be prevented from being displaced in the left-right direction.

Alternatively, instead of providing the above-described nip portion 100 or nip member 101, nip portions 102 may be provided in both left and right end portions of the shielding plate portion 94 of the light-shielding sheet 9. For example, as shown in fig. 14 (a), holes 102a having elastically deformable nipping portions 102 are provided in both left and right end portions of the shielding plate portion 94, and the nipping portions 102 are pressed from the holes 102a to be elastically deformed as shown in fig. 14 (b), whereby the fabric 13 is nipped as shown in fig. 14 (c). By providing the nip portion 102 which can be elastically deformed by external pressure in this manner, the fabric 13 can be prevented from being displaced in the left-right direction.

(constitution example of light-shielding sheet)

Fig. 15 (a), (b), and (c) show typical examples of the configuration of the shade sheet 9 in various shading devices (including devices other than the roller blind 1). Fig. 15 (a) shows the structure of the light-shielding sheet 9 according to the embodiment described above with reference to fig. 3 and the like.

In the example shown in fig. 15 (b), the projecting piece 96b is not provided as compared with the configuration shown in fig. 15 (a), and other elements are the same. That is, in the example shown in fig. 15 (b), since the projection piece 96b is not provided, the projection piece 96a and the claw portion 99 constitute a clamping mechanism functioning as a cloth holding plate, and the cloth 13 is fixed and hung down, and therefore there is a possibility that the cloth 13 is shaken when the shade sheet 9 is rotated or the like, but from other viewpoints, all the functions and effects of the shade sheet 9 of the one embodiment shown in fig. 15 (a) and described above with reference to fig. 3 and the like can be obtained, and the modified example thereof can be applied.

Further, fig. 15 (c) shows a typical example in which the light-shielding sheet 9 is not required to be rotated, as compared with the configuration shown in fig. 15 (a). That is, the shaft 91 is formed in a shape capable of being fixed to the mounting bracket 2, or the length of the shielding plate 94 is shortened, and the cloth 13 has a light shielding function. Therefore, the characteristic elements according to the above invention can be appropriately selected and used, and can be modified according to the application.

Fig. 16 (a) and (b) are perspective views showing two structural examples relating to attachment of the cloth 13 to the shade sheet 9 in one example of the roll screen 1 according to the present embodiment.

Fig. 16 (a) is a detailed view of the light-shielding sheet 9 shown in fig. 3 when the thick cloth 13 is held between the protruding piece 96a and the claw 99 which constitute the holding mechanism. When the thick cloth 13 is sandwiched by the protruding pieces 96a and the claw portions 99, the protruding pieces 96a are elastically deformed, and a-a 'indicating the longitudinal direction of the shielding plate portion 94 and B-B' indicating the longitudinal direction of the protruding pieces 96a are not parallel to each other. In a case where it is desired to further improve the point that the protruding piece 96a is not parallel to the shield plate portion 94 from the viewpoint of appearance, the clamping mechanism as the cloth 13 on the shade sheet 9 may be configured as shown in fig. 16 (b).

In the example shown in fig. 16 (b), the gripping means for the cloth 13 on the light-shielding sheet 9 is constituted by the projection piece 96a and the nip portion 100 shown in fig. 12 without providing the claw portion 99. The projecting piece 96a at this time is formed of a rigid body that is not elastically deformable. The nip portion 100 is formed by attaching the cloth 13 to the shade sheet 9 at both left and right end portions of the shade plate portion 94 of the shade sheet 9, and then performing permanent deformation by caulking using a jig such as a nipper. Thus, even with a thick cloth 13, the cloth 13 can be attached to the light-shielding sheet 9 in a state where a-a 'indicating the longitudinal direction of the shielding plate portion 94 and B-B' indicating the longitudinal direction of the projection piece 96a are almost parallel.

The present invention has been described above by way of examples of specific embodiments, but the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the technical spirit thereof. In particular, the shape and structure of the shaft portion 91 of the shade 9 and the locking method thereof have been described by way of example only, and the shaft portion 91 of the shade 9 may be formed by a circular shaft or the like, for example, and in the case of a roller blind, for example, the configuration may be such that: the shaft 91 of the shade 9 is supported by the

support members

2a, 2b, not by the mount frame 2 as a frame. The position of locking the shaft portion 91 of the light-shielding sheet 9 to the mount 2 is not limited to the front surface of the mount 2, and may be the back surface or the bottom surface of the mount 2. As a form in which the shade sheet 9 can be used, there are a horizontal blind, a roll-up curtain, a pleated curtain, and the like, in addition to a roll screen.
