In the direction (or upper side) and the lower direction (or lower side), the left direction is defined as the left side of the roller blind, and the right direction is defined as the right side of the roller blind. Further, in the example described below, with respect to the front view of the roller blind shown in Fig. 1, the visible side is referred to as the front side (or the indoor side), and the opposite side is referred to as the rear side (or the outdoor side), and is referred to as a roll. The front-rear direction of the curtain refers to a direction perpendicular to the illustrated surface of the front view shown in Fig. 1. [First Embodiment] (Device Structure)

First, the structure of a roller blind as a shielding device according to a first embodiment of the present invention will be described with reference to Figs. 1 and 2 . Fig. 1 is a front elevational view showing a schematic configuration of a roller blind as a shielding device according to a first embodiment of the present invention. Fig. 2 is a partial side perspective view showing a schematic configuration of a roller blind as a shielding device according to a first embodiment of the present invention.

In the roller blind shown in Fig. 1, support members 1a and 1b are fixed to both ends of the mount 1, and a cylindrical winding tube is used by a fixed shaft (not shown) extending from the support members 1a and 1b. 2 is rotatably supported between the support members 1a, 1b. The mounting bracket 1 is fixed to the top surface S by the bracket 6.

The winding tube 2 mounts one end of the curtain 3 and suspends it to be capable of winding. The other end of the curtain 3 is attached to a weight bar 4 that functions as a weight member. Therefore, the curtain 3 is tensioned by the weight of the weight bar 4.

Further, in the winding tube 2, a winding mechanism (for example, a spring motor) for automatically rolling up the curtain 3 and a restriction device (not shown) for preventing the curtain 3 from falling due to its own weight are housed. Therefore, when the restriction device does not operate, the winding tube 2 is operated to rotate in the curtain winding direction by the winding mechanism.

Further, a handle 5 that can be pulled downward is attached to a lower end portion of a substantially central portion of the weight bar 4. As shown in FIG. 2, the handle 5 is suspended from a part of the handle support 4a that houses the weight bar 4 via the wire 5a.

In other words, when the handle 5 is pulled downward, the winding tube 2 is rotated in the unwinding direction of the curtain to lower the weight bar 4, and when the handle 5 is released at an arbitrary position, the curtain 3 is stopped by the restriction device. When the handle 5 is pulled slightly downward from this state and the hand is released, the lock of the restriction device is released, and the winding tube 2 is rotated in the curtain winding direction to raise the weight bar 4. In this way, by winding or unwinding the curtain by the winding tube 2, the amount of light collected into the room can be adjusted.

Further, instead of or in addition to the handle 5, an operation pulley may be provided at one end portion of the winding tube 2, and an annular operation wire wound around the operation pulley may be suspended to enable winding of the curtain. Or open the volume. For example, the operation wire may be constituted by a ball chain, and the surface of the operation pulley around which the ball chain is wound may be configured to have irregularities suitable for the shape of the ball portion of the ball chain.

Further, in the roller blind of the present invention, as shown in FIGS. 1 and 2, a light leakage preventing member 7 is provided which prevents the upper portion from the top surface S and the roller blind (in this example, the mounting bracket 1) The gap between the upper portions) leaks light and effectively blocks light leakage from the gap generated between the winding tube 2 and the mounting frame 1. The light leakage preventing member 7 is composed of a clamp member 71 and a suspension shutter 72. In particular, although the clamp member 71 will be specifically described later, as shown in FIG. 2, the clamp member 71 can be divided into a main body portion 71a, a distal end portion 71b, and a proximal end portion 71c, and the main body portion 71a and the proximal end thereof based on the side cross-sectional shape thereof. The width of the portion 71c in the left-right direction extends to be substantially the same length as the width of the roller blind in the left-right direction, and the distal end portion 71b extending rearward from the main body portion 71a extends in the left-right direction at a position other than the region in which the bracket 6 is provided. Further, the width of the suspension shutter 72 in the left-right direction also extends to a length substantially the same as the width of the roller blind in the left-right direction. As the "substantially the same length", the width of the suspension shutter 72, the main body portion 71a of the clamp member 71, and the proximal end portion 71c in the left-right direction may be determined according to the use, and may be slightly longer than the width of the roller blind in the left-right direction. It can also be a little shorter on the contrary.

The distal end portion 71b of the clamp member 71 has a shape capable of being inserted into the gap between the top surface S and the upper portion of the roller blind (in this example, the upper portion of the mounting bracket 1). Further, the proximal end portion 71c of the clamp member 71 has a shape in which the upper edge portion 72a of the suspension shutter 72 is suspended and supported in a state where the length of the suspension can be adjusted. Further, in the lower edge portion 72b of the suspension shutter 72, as illustrated in Fig. 2, in order to maintain the quality thereof, it is preferable to bend and perform the end treatment, and the length of the hanging can be adjusted and welded by welding or the like. Bonding, but it is also possible to adjust the length by using a fastening tape or the like.

The light leakage preventing member 7 can be detachably attached to the front side (indoor side) of the roller blind, and is configured to be easily attached and detached as will be described later, and is configured such that the light leakage preventing member 7 after mounting can be stably shielded from light. Therefore, regarding the installation of the light leakage preventing member 7, the workability and the detachability of the roller blind can be improved, and the light blocking property at the time of curtain occlusion can be improved. Hereinafter, the light leakage preventing member 7 according to an embodiment of the roller blind of the present embodiment will be described in more detail with reference to Figs. 3 to 6 . (light leakage prevention member)

Fig. 3 is a side view showing a schematic configuration of a light leakage preventing member 7 according to an embodiment of the roller blind of the embodiment. The light leakage preventing member 7 is composed of a clamping member 71 and a suspension shutter 72. In particular, the clamp member 71 can be divided into a main body portion 71a, a distal end portion 71b, and a proximal end portion 71c based on the side cross-sectional shape thereof. The width of the main body portion 71a and the base end portion 71c in the left-right direction extends to be substantially the same length as the width of the roller blind in the left-right direction, and the distal end portion 71b extending rearward from the main body portion 71a extends in the left-right direction at a position other than the bracket 6. For example, as shown in FIG. 4, the width of the main body portion 71a and the base end portion 71c of the clamp member 71 in the left-right direction is formed to extend slightly longer than the width in the left-right direction of the roller blind as the "substantially the same length", and the distal end portion is formed. The width in the left-right direction of 71b can be formed to extend in a region (illustration A) other than the installation region (illustration B) of the bracket 6. In FIG. 4, the distal end portion 71b is not formed in the region where the support members 1a and 1b are present. However, the distal end portion 71b may be formed in the region where the support members 1a and 1b are present.

As shown in Fig. 3, as described above, the distal end portion 71b of the clamp member 71 has a shape capable of being inserted into the gap between the top surface S and the upper portion of the roller blind (in this example, the upper portion of the mounting bracket 1). Further, the proximal end portion 71c of the clamp member 71 has a shape in which the upper edge portion 72a of the suspension shutter 72 is suspended and supported in a state where the length of the suspension can be adjusted.

In the distal end portion 71b of the clamp member 71, rib-shaped fins 11, 12, 13, and 14 that protrude upward and downward, respectively, are formed. The pleated fins 11, 12, 13, and 14 are formed of a highly elastic soft material (illustrated by diagonal lines), and on the other hand, the other regions of the distal end portion 71b, the main body portion 71a, and the proximal end portion 71c are made of a low-elastic hard material. Material formation (illustrated by a blank line) is formed by so-called two-color molding. Further, the material of the pleated fins 11, 12, 13, and 14 may be a plurality of different materials, that is, the clamp member 71 may be formed by multicolor molding. Alternatively, the fins 11, 12, 13, and 14 may be formed by two-color or multi-color molding instead of being formed by bonding or the like. Further, although the fins 11, 12, 13, and 14 are extended to have substantially the same length as the width of the roller blind in the left-right direction except for the position of the bracket 6, the left and right directions of the roller blind may be formed. Multiple locations stand out.

Any one of the upper fins 11, 12, 13 is formed to change the height to press the top surface S. In the illustrated example, the fins 11 in the upper fins 11, 12, 13 are higher in height than the fins 12, 13. By changing the heights of the upper fins 11 , 12 , and 13 in this manner, even when the top surface S has irregularities, for example, the unevenness can be absorbed and the top surface S can be pressed. In this way, the fins provided above the distal end portion 71b are transmitted through a plurality of or changed heights, and the distal end portion 71b can be inserted between the top surface S and the upper portion of the roller blind (in this example, the upper portion of the mounting bracket 1). The state of the gap is stabilized.

The lower fin 14 functions as a retaining function to hold the tip end portion 71b inserted into the gap between the top surface S and the upper portion of the mounting frame 1. In other words, as long as the external force required to remove the clamp member 71 does not occur, the distal end of the lower fin 14 can abut against the inner side of one side wall of the upper opening of the mount 1, and the insertion of the distal end portion 71b can be stably maintained (refer to figure 2).

Further, since the pleated fins 11, 12, 13, and 14 are formed of a highly elastic soft material as compared with other regions, the insertion of the distal end portion 71b is facilitated, and the detachment of the clamp member 71 is facilitated (i.e., The tip portion 71b is ejected). Further, as shown in the drawing F, the pleated fins 11, 12, 13, and 14 have a concave shape (a shape having a retracting function at the time of deformation) in consideration of retraction at the time of deformation. Thereby, even when the top surface S has irregularities, the unevenness can be effectively absorbed to press the top surface S, and the stable holding can be improved. Further, the upper fins 11, 12, and 13 and the lower fins 14 may be soft materials of different materials.

The length of the main body portion 71a of the clamp member 71 in the front-rear direction (the length in the left-right direction shown) can be changed according to the applied shutter device, and can be determined to be applicable to the length of the plurality of shutter devices.

Further, protrusions 15 and 16 projecting downward are provided on the distal end portion 71b and the main body portion 71a of the clamp member 71, respectively. The protruding portion 15 of the distal end portion 71b is provided at a position that can be supported by an upper portion of the side wall of the upper opening of the mounting frame 1, and the protruding portion 16 of the main body portion 71a is provided at a side wall outer portion that can be opened to the upper portion of the mounting frame 1. Position (refer to Figure 2). It is also possible to form the clamping member 71 without providing the protruding portion 15, but as will be described later, the top end portion 71b of the clamping member 71 is inserted into the top surface S and the upper portion of the roller blind (in this example, the upper portion of the mounting bracket 1) When the gap between the protrusions 15 acts as a fulcrum and is advantageous in stabilizing the horizontal level, it is preferable to provide the protrusions 15. Further, as will be described later, the protruding portion 16 has an abutting surface that is substantially perpendicular to the horizontal direction for preventing excessive insertion, and is also advantageous in that the level is kept stable. In other words, by providing the projections 15 and 16 that protrude downward in the distal end portion 71b and the main body portion 71a of the clamp member 71, the horizontal retention of the clamp member 71 can be further stabilized.

The base end portion 71c of the clamp member 71 can support the upper edge portion 72a of the suspension shutter 72 in a folded state, so that the hanging length of the suspension shutter 72 can be adjusted. . In the example shown in FIG. 3, the base end portion 71c is formed with a substantially C-shaped holding space formed by the shielding piece 17 and the cloth holding portion 18, and the upper edge portion 72a of the suspension shutter 72 is locked to enable the suspension. The shutter 72 is suspended downward from the cloth discharge portion 19.

Further, the upper surface portion 10 of the main body portion 71a of the clamp member 71 and the upper surface of the shielding piece 17 of the base end portion 71c are formed to have a step (height difference) when the clamp member 71 is in the horizontal state shown in FIG. Preferably, the upper surface (top portion) of the shielding sheet 17 is formed as the top of the highest fin (the fin 11 in the illustrated example) and the main body portion 71a of the upper fins 11, 12, 13 Between the surface portions 10. Thereby, the level of the clamp member 71 can be stabilized. Further, although the shielding piece 17 of the proximal end portion 71c is formed as a flat upper surface as an example, it may be formed in a curved shape that is convex upward or convex downward.

The light leakage preventing member 7 configured as described above can be attached and detached from the front side (indoor side) of the roller blind, and is configured to be easily attached and detached, and the light leakage preventing member 7 is stably held during mounting. Here, the method of mounting the light leakage preventing member 7 and the effect of its stable holding will be described in detail. As shown in Fig. 5 (a), the distal end portion 71b of the clamp member 71 in the light leakage preventing member 7 is inserted into the top surface S and the upper portion of the roller blind from the front side (indoor side) of the roller blind (i.e., the mount 1) In the gap between the upper portions, stable holding can be performed as shown in Fig. 5(b). More specifically, any one of the upper fins 11, 12, 13 (the fin 11 in the illustrated example) presses the top surface S, and the lower fin 14 has a function of preventing the detachment, and the projection 15 is mounted on the mount One side wall of the upper opening of the upper opening 1 is supported, and the protruding portion 16 is provided to be able to abut against a side wall outer portion of the upper opening of the mounting frame 1.

Further, as shown in FIG. 6, even if the rotation force in the direction of the arrow is generated with the protrusion 15 as the fulcrum due to the other, the fin 11 presses the top surface S, and the upper surface (top) and the top surface S of the visor 17 Abutting, the clamping member 71 is thus kept almost horizontal and can prevent a gap from being formed between the top surface S and the upper portion of the roller blind (i.e., the upper portion of the mounting bracket 1).

According to the roller blind of the first embodiment configured as described above, it is possible to prevent light leakage from the gap between the top surface S and the upper portion of the mounting frame 1, and to be able to pass between the winding tube 2 and the lower portion of the mounting frame 1. The light leakage of the generated gap is effectively shielded from light, so that the blocking performance can be improved. Moreover, the workability and detachability of the light leakage preventing member 7 can be facilitated. Here, the term "shielding performance" includes, in addition to preventing light leakage, an effect of preventing ventilation (sealing effect) due to the gap. [Second Embodiment] (Device Structure)

Next, a structure of a roller blind as a shielding device according to a second embodiment of the present invention will be described with reference to Fig. 7 . Fig. 7 is a front elevational view showing the schematic configuration of a roller blind as a shielding device according to a second embodiment of the present invention.

The roller blind of the present embodiment is an example in which the tension rod 8 is used in order to provide the bracket 6 at a position where the bracket 6 cannot be directly fixed. The tension bar 8 is a member for securing the mounting surface of the roller blind at a position where the side wall portion for mounting on the top of the inner frame is attached to the top of the inner frame, and the top surface S is close to the top surface S, and is substantially rectangular. Both ends of the main body can be fixed between the side wall portions by tensioning and applying without using screws.

In the case where the main body of the roller blind is provided by the tension bar 8, the main body of the roller blind is fixed to the tension bar 8 via the bracket 6. Therefore, generally, a gap is generated between the top surface S and the tension rod 8, between the tension rod 8 and the mounting frame 1, and between the mounting frame 1 and the winding tube 2, but in the present embodiment, The top end portion 71b of the clamp member 71 of the light leakage preventing member 7 shown in Fig. 3 is inserted between the top surface S and the tension rod 8, and the suspension shutter 72 is suspended from the base end portion 71c of the clamp member 71 to prevent the top. The gap between the face S and the tensioning rod 8, between the tensioning rod 8 and the mounting frame 1, and between the mounting frame 1 and the winding tube 2.

In the roller blind of the second embodiment configured as described above, it is possible to prevent the gap between the top surface S and the tension rod 8 and the gap between the tension rod 8 and the mounting frame 1 from leaking light, and it is also possible to The light leakage of the gap generated between the mounting frame 1 and the winding tube 2 is effectively shielded from light, and the shielding performance can be improved. Further, similarly to the first embodiment, the workability and detachability of the light leakage preventing member 7 are also facilitated.

Further, the shape of the clamp member 71 of the light leakage preventing member 7 can be realized by various modifications. For example, as shown in FIG. 8(a), the heights of the upper fins 11, 12, and 13 may be substantially the same. Moreover, as shown in FIG. 8(b), the shape in which the protrusion part 16 and the cloth holding part 18 are integrated may be formed. Further, as shown in FIG. 8(c), the shielding piece 17 and the cloth holding portion 18 may be formed in a substantially plate shape, and the hanging shutter 72 may be adhered to the surface of the cloth holding portion 18 by a fastening tape, welding or the like. And/or the face of the shielding sheet 17.

Further, as shown in FIG. 9(a), the upper fins 11 may be one, or may be two or four. Further, as shown in FIG. 9(b), the shape of the upper and lower fins 11 and 14 may be pleated (see FIG. 9(b)) and cylindrical (see FIG. 9). (c)). Further, the elements shown in FIGS. 8 and 9 may be combined as appropriate to form the clamp member 71.

Further, the suspension shutter 72 may be formed of a resin-formed member that is not a cloth. Further, the fins illustrated in FIGS. 3, 8, and 9 further include a shape other than the above, and when formed of a highly elastic soft material, it is preferably formed as described above with reference to FIG. It has the shape of the backoff function. (Example of light leakage preventing member that constitutes a clamping member from a plurality of members)

Further, the clamp member 71 of the light leakage preventing member 7 can be composed of a plurality of members. For example, the clamping member 71 of the embodiment shown in the partial perspective view of FIG. 10(a) and the partial cross-sectional view of FIG. 10(b) is composed of the clamping element member 71A and the clamping element member 71B, wherein the clamping element member 71A The clamp element member 71B is attached to the mounting bracket 1 at a plurality of positions in the left-right direction of the clamp element member 71A in a length that is substantially the same as the width in the left-right direction of the roller blind. The clamp element member 71A is formed of a low-elasticity hard material, and the clamp element member 71B is formed of a highly elastic soft material. The example shown in FIG. 10 is an example in which the clamp element member 71A and the clamp element member 71B are integrated to form the light leakage preventing member 7, and then attached to the roller blind. In addition, in FIG. 10, structural elements which have the same function as the clamp member 71 shown in FIG. 3 are denoted by the same reference numerals.

The clamp element member 71A of the clamp member 71 of the present embodiment can also be divided into a main body portion 71a, a distal end portion 71b, and a proximal end portion 71c. Further, in the present embodiment, the width of the main body portion 71a and the base end portion 71c in the left-right direction extends to be substantially the same length as the width of the roller blind in the left-right direction, and the distal end portion 71b extending rearward from the main body portion 71a is in addition to the bracket 6. The other positions extend in the left-right direction (not shown).

As shown in Fig. 10, a protruding piece 11a that protrudes upward is formed in the distal end portion 71b of the clamp element member 71A of the present embodiment. The protruding piece 11a is preferably formed of a highly elastic soft material, but is formed of a low-elastic hard material similarly to the other regions of the distal end portion 71b, the main body portion 71a, and the proximal end portion 71c. Further, by using the projecting piece 11a formed of a highly elastic soft material, the level of the clamp member 71 can be effectively stabilized in the present embodiment as will be described later.

In the same manner as in the above-described embodiment, the base end portion 71c is formed in a substantially C-shaped shape by the shielding piece 17 and the cloth holding portion 18 in order to suspend and support the upper edge portion 72a of the suspension shutter 72. In the space, the upper edge portion 72a of the suspension shutter 72 is locked, so that the suspension shutter 72 can be suspended downward from the cloth discharge portion 19.

Further, in the clamp element member 71A of the present embodiment, the distal end portion 71b is inserted into the gap between the top surface S and the upper portion of the roller blind (in this example, the upper portion of the mounting bracket 1), thereby The lower surface of the distal end portion 71b of the clamp element member 71A is supported by the upper portion of the mounting frame 1 to prevent the light leakage. However, the insertion state cannot be stabilized only by the clamp element member 71A.

Therefore, in the clamp element member 71A of the present embodiment, the main body portion 71a and the distal end portion 71b which are extended to have the same length as the width of the roller blind in the left-right direction are formed at a plurality of positions in the left-right direction. A pair of long hole-shaped locking holes 31 and a square cutout 32. By the locking hole 31 and the slit 32, the clamp element member 71B made of a highly elastic soft material is locked to the clamp element member 71A and integrated, thereby assisting the clamp element member 71A with respect to the mount 1. installation.

However, the insertion state cannot be stabilized only by the clamp element member 71A.

Therefore, the substantially C-shaped clamp element member 71B formed of the low-elasticity hard material of the present embodiment is locked to the one side portion (indoor side portion) of the mounting frame 1 and integrated, and the clamp element member 71B is used. The upper end portion 55 supports the projection portion 54 of the clamp element member 71A, thereby assisting the attachment of the clamp element member 71A with respect to the mounting bracket 1.

More specifically, as shown in FIG. 12(b), the clamp element member 71B of the present embodiment has a main body 51 having a substantially C-shaped cross-sectional shape, and a fitting claw portion is formed at a substantially central portion and a lower end portion of the main body 51, respectively. 52, 53, the fitting claw portions 52, 53 protrude in the direction in which the mounting bracket 1 is mounted. Further, fitting receiving portions 1c and 1d projecting upward and downward are formed at the upper end and the lower end of the one side portion (indoor side portion) of the mounting frame 1, respectively.

The top end portion 71b is inserted into the gap between the top surface S and the upper portion of the mounting frame 1. For example, in a state where the clamp element member 71B is integrated with one side portion (indoor side portion) of the mounting frame 1, the distal end portion 71b of the clamp element member 71A is inserted between the top surface S and the upper portion of the mounting frame 1. In the gap, the projection 54 of the clamp element member 71A presses the upper end portion 55 of the clamp element member 71B and elastically deforms and straddles.

Further, the upper protruding portion 11c may be provided to extend in the left-right direction of the roller blind at a position other than the bracket 6, but may be dispersed in a plurality of positions.

When the clamp element member 71B is locked to the mount 1 and integrated with the clamp element member 71A, the distal end portion 71b of the clamp member 71A can be inserted into the top surface S (in this example, The gap between the upper portion of the mounting frame 1 and the upper portion of the roller blind stabilizes the level.

The present invention has been described with reference to the specific embodiments. The present invention is not limited to the examples of the embodiments described above, and various modifications can be made without departing from the spirit and scope of the invention. For example, in each of the above-described embodiments, the shutter is mainly described as a shutter, and the light leakage preventing member 7 can be applied to the curtain track as long as it is a device that creates a gap between the top surface and the main body of the shutter. Other shielding devices such as horizontal blinds, vertical blinds, pleated blinds, and roll-up curtains (Roman blinds).

For example, FIG. 13 is a perspective view showing a schematic configuration of a curtain rail 100 as a shielding device according to a third embodiment of the present invention. In the curtain track 100 of the illustrated example, a movable bracket 102 is supported on each of the two rails 101, and a curtain member (not shown) as a shutter is suspended from the bracket 102. Each track 101 is mounted on the top surface via a bracket 106. At this time, a gap may occur between the top surface and each of the rails 101, and between the rails 101 and the upper side of the curtain (the position of the bracket 102), and light leakage may occur. Therefore, the tip end portion 71b of the clamp member 71 is inserted between the top surface and each of the rails 101 by, for example, the light leakage preventing member 7 illustrated in Fig. 3, whereby the clamp member 71 itself and the hanging from the base end portion 71c thereof can be used. The shutter 72 is suspended to prevent light leakage from the gap between the top surface and each of the rails 101 and between the rails 101 and the upper side of the curtain member (the position of the bracket 102). Further, the light leakage preventing member of the present invention can also be applied to a curtain track using one or three or more tracks.

In addition, FIG. 14 is a perspective view showing a schematic configuration of a crease 200 as a shielding device according to a third embodiment of the present invention. In the crease 200 of the illustrated example, the curtain 203 as a shutter is suspended from the upper beam 201. The upper beam 201 is attached to the top surface via a bracket 206. At this time, a gap is generated between the top surface and the upper beam 201, and light leakage occurs. In addition, when the upper beam 201 can be seen, the appearance is impaired. Therefore, the light leakage preventing member 7 illustrated in Fig. 3 is inserted between the top surface and the upper beam 201 by the tip end portion 71b of the clamp member 71, thereby preventing light leakage from the gap between the top surface and the upper beam 201, thereby utilizing The suspension shutter 72 whose base end portion 71c of the clamp member 71 is suspended with a predetermined length d1 can avoid the visibility of the upper beam 201 having the height d2 (<d1), thereby improving the appearance.

As such a shielding device for hanging the shutter from the upper beam, the light leakage preventing member 7 can be prevented from being prevented from between the top surface and the upper beam by the light blocking preventing member 7 in the same manner as the shielding device such as the horizontal blind or the roll curtain (roman blind). The gap leaks light and avoids the visibility of the upper beam to improve its design.

Further, in the shielding device in which the shutter is suspended from the upper beam, when the operation wire and the operation bar are exposed from the upper beam to the indoor side and are suspended, it is preferable to be on the indoor side of the hanging position. The position causes the suspension shutter 72 to hang down from the light leakage preventing member 7. For example, as shown in FIG. 14, the suspension shutter 72 is suspended from the light leakage preventing member 7 at a position on the indoor side of the hanging position of the operation wire 204. Thereby, the appearance can be improved. Further, by setting the shape of the clamp member 71 (for example, the length of the main body portion 71a), the hanging position of the suspension shutter 72 can be set.

Further, in each of the above-described embodiments and examples, an example in which the light leakage preventing member 7 is attached from the front surface (front surface) of the shielding device has been mainly described. However, this is a preferred example and may be from the rear of the shielding device (back surface). The light leakage preventing member 7 is installed. Further, the light leakage preventing member 7 may be provided on the front and rear surfaces of the shielding device, or may be provided on the side surfaces of the left and right end faces of the shielding device (for example, covers provided at the left and right end portions of the shielding device). Further, when the purpose of preventing light leakage by the gap between the closed shielding device and the top surface is used, the use of the clamp member 71 to which the suspension shutter 72 is not attached can be applied to the shielding device.

Further, in the case where the light leakage preventing member 7 is applied to other shielding devices such as a curtain rail, a horizontal blind, a vertical blind, a pleated blind, and a roll up curtain (Roman blind) by using a tension bar, it is also possible to obtain The same actions and effects as those of the second embodiment described above. (industrial applicability)

According to the present invention, it is possible to prevent leakage of light from the gap between the top surface and the upper portion of the shielding device, and it is possible to improve the workability and detachability, and therefore it is useful for the use of the shielding device for suspending the shielding member.
