Description

Shielding device

The present invention relates to a shielding device capable of opening and closing a shielding material.

Conventionally, there are roll screens, horizontal blinds, scooping curtains, pleated screens, etc. as shielding devices that can open and close the shielding material.

For example, a roll screen supports a winding shaft by a frame, attaches the upper edge of the screen to the winding shaft and hangs down, and provides a weight member at the lower edge of the screen, thereby winding the roll screen. The screen can be wound or rewound by a shaft so that the amount of light collected in the room can be adjusted.

Therefore, in order to prevent a gap between the winding shaft for winding the screen and the lower surface of the frame body that supports the winding shaft, the base end edge is rotatably supported on the lower surface of the frame body. A technique of providing a gap preventing member that hangs down on the peripheral surface of the shaft is disclosed (for example, see Patent Document 1).

By the way, in a horizontal blind using a large number of slats as a shielding material, a technique for detachably installing a decorative board using the slats by providing a groove in the head box (see, for example, Patent Document 2) or a curtain material is used. A technique is known in which a curtain is used as a shielding material, and a groove is provided in the head box and one end of the curtain material is detachably attached with a hook-and-loop fastener (for example, see Patent Document 3).

Japanese Utility Model Publication No. 4-48316 Japanese Utility Model Publication No. 3-1994 Japanese Patent No. 3098924

In the technique disclosed in Patent Document 1 described above, since the gap prevention member can close the gap between the winding shaft and the lower surface of the frame (or mounting frame), the screen is lowered to be in a shielding state. This is effective in that it can improve the light-shielding property.

However, since it is necessary to attach the base edge of the gap prevention member to the lower surface of the frame, the gap prevention member cannot be easily attached, and there is room for improvement in terms of assembly.

By the way, in the technique disclosed in Patent Document 2, a groove for holding a slat that is rigid and does not buckle is provided in the head box, and a decorative board using the slat is configured to be detachably installed.

Further, when the shape of the slat changes, the head box must be changed, and there is no adaptability to various types of horizontal blinds. Further, it is difficult to apply the shielding material to a soft material such as a cloth, and there is no applicability to various kinds of shielding devices.

The technique disclosed in Patent Document 3 does not require the function as the gap prevention member by detachably attaching one end of the curtain material with a hook-and-loop fastener. It is not intended to function as a prevention member, and is intended to be applicable only to tucked curtains. Even if the head box is provided with a groove so that one end of the curtain material is detachably attached with a hook-and-loop fastener, it is not easy to attach a long, soft material curtain material.

FIG. 5 is a perspective view illustrating a schematic configuration of the light leakage preventing member 6 of Example 2 in the roll screen 1 according to the embodiment of the first aspect of the present invention. 6 (a) and 6 (b) are side views for explaining the light leakage preventing member 6 of Example 2 in the roll screen 1 according to the embodiment of the first aspect of the present invention and a modification thereof. FIGS. 7A, 7B, 7C and 7D respectively show a fixing member 7 for fixing the light leakage preventing member 6 of Example 2 in the roll screen 1 according to the embodiment of the first aspect of the present invention. It is a perspective view which shows the other example.

A roll screen 1 shown in FIG. 1 has

support members

2a and 2b fixed to both ends of a mounting frame 2, and a cylindrical winding pipe between the

support members

2a and 2b by a fixed shaft 11 extending from the support members 2a and 2b. 9 is rotatably supported. The mounting frame 2 is fixed to the attachment surface by a bracket 5.

An operation pulley 10 is provided at the right end of the winding pipe 9, and an endless operation cord 3 hung around the operation pulley 10 is suspended. And it is comprised so that the winding pipe 9 can be rotated by operation of the operation cord 3, and the surface of the operation pulley 10 on which the operation cord 3 is wound has a highly frictional surface shape. The operation cord 3 may be constituted by a ball chain, and the surface of the operation pulley 10 around which the ball chain is hung may be configured so as to have irregularities having a shape suitable for the ball portion of the ball chain.

The take-up pipe 9 is attached to one end of the screen 4 and supported in a suspended manner so that it can be taken up. The other end of the screen 4 is attached to a weight bar 8 that functions as a weight member. Accordingly, the screen 4 is stretched based on the weight of the weight bar 8.

When the operation cord 3 is operated to rotate the winding pipe 9 in the screen winding direction, the weight bar 8 is raised, and when the winding pipe 9 is rotated in the screen unwinding direction, the weight bar 8 is lowered.

Further, in the take-up pipe 9, 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 dropping is housed on the right end side ( Not shown).

Therefore, in the roll screen 1 according to the present invention, the external light from the gap generated between the winding pipe 9 and the mounting frame 2 is effectively shielded, and the light shielding property at the time of shielding is improved while improving the assembling property. The light leakage prevention member 6 is provided so that the light leakage prevention member 6 of each embodiment will be described below.

(Light Leakage Prevention Member of Example 1)
First, with reference to FIG. 2, the light leakage prevention member 6 of Example 1 and the fixing member 7 which fixes the light leakage prevention member 6 to the to-be-fixed part 21 of the front surface of the attachment frame 2 are demonstrated.

As shown in FIG. 2, a fixed portion 21 having a substantially C-shaped cross section extending in the longitudinal direction is formed on the front surface of the mounting frame 2. The light leakage prevention member 6 of Example 1 is made of a light-shielding soft cloth. The fixing member 7 has a substantially circular cross-section engaging portion 7a that can be engaged with the fixed portion 21 with the light leakage preventing member 6 sandwiched therebetween, and protrudes from the engaging portion 7a into a substantially U-shape. 6 has a guide bar 7b for guiding the hanging position. Here, the “soft fabric” refers to a fabric having a hardness enough to bend and hang down by its own weight from the fixing point of the fabric.

That is, the vicinity of one edge portion of the light leakage preventing member 6 is sandwiched by the engaging portion 7 a of the fixing member 7 and engaged with the fixed portion 21, and the other edge portion of the light leakage preventing member 6 causes the fixing member 7 to be engaged. Covered and drooped.

As shown in FIG. 3A, the light leakage preventing member 6 according to the first embodiment configured as described above hangs down from the fixed portion 21 on the front surface of the mounting frame 2 along the guide bar 7b of the fixing member 7. The external light incident from between the mounting frame 2 and the winding pipe 9 can be shielded. Moreover, since the light leakage prevention member 6 can be attached and fixed from the front (inside of the room) of the roll screen 1, it is excellent in assemblability.

Further, since the fixing member 7 can be attached to the mounting frame 2 after the bracket 5 is fixed to the mounting surface and the mounting frame 2 is mounted to the bracket 5, the mounting frame can be viewed in a state where the bracket 5 is visually recognized at the time of construction. 2 can be attached, and there is an advantage that workability when fixing the attachment frame 5 to the bracket 6 is not impaired.

Further, since the light leakage preventing member 6 of the first embodiment is made of a light-shielding soft cloth and the fixing member 7 has a guide bar 7b, the screen 4 is taken up by a winding pipe 9 as shown in FIG. Even when it is wound up and thickened like the winding diameter R, the light leakage prevention member 6 bends and follows this thickening, so that it is attached regardless of the winding state of the screen 4 by the winding pipe 9. External light incident between the frame 2 and the winding pipe 9 can be shielded with high shielding properties.

In the light leakage prevention member 6 of the first embodiment described above, an example in which the vicinity of one edge portion of the light leakage prevention member 6 is sandwiched by the engagement portion 7a of the fixing member 7 and engaged with the fixed portion 21 has been described. However, as a modification, for example, as shown in FIG. 4A, the vicinity of one edge of the light leakage prevention member 6 is fixed to the guide bar 7b of the fixing member 7 by the engaging means 7c by staple or sewing. In addition, the engaging portion 7a of the fixing member 7 may be directly engaged with the fixed portion 21 (see FIG. 4B). Also in this case, all the functions and effects of the light leakage prevention member 6 of the first embodiment are provided.
For example, the light leakage prevention member 6 bends and becomes thicker when it is made up of a light-shielding soft fabric, as shown in FIG. Therefore, the external light incident between the mounting frame 2 and the winding pipe 9 can be shielded with high shielding properties regardless of the winding state of the screen 4 by the winding pipe 9. And workability at the time of fixing the attachment frame 5 to the bracket 6 is not impaired.

In the above-described example, the example in which the light leakage preventing member 6 of the first embodiment or the modification thereof is attached to the front surface of the mounting frame 2 has been described. However, the light leakage preventing member of the first embodiment is mounted on the rear surface of the mounting frame 2. 6 can be obtained, the same effect can be obtained. In this case, the light leakage prevention member 6 can be attached and fixed from the back surface (outside of the roll screen 1). Are better.

(Light Leakage Prevention Member of Example 2)
Next, with reference to FIG. 5, the light leakage prevention member 6 of Example 2 and the fixing member 7 which fixes the light leakage prevention member 6 to the to-be-fixed part 21 of the front surface of the attachment frame 2 are demonstrated.

As shown in FIG. 5, a fixed portion 21 having a substantially C-shaped cross section extending in the longitudinal direction is formed on the front surface of the mounting frame 2. The light leakage prevention member 6 of Example 2 is made of a light-shielding hard cloth. The fixing member 7 has a substantially reverse C-shaped cross section that can be engaged with the fixed portion 21 with the light leakage prevention member 6 interposed therebetween, and a substantially horizontal T-shape projecting from the engaging portion 7a. A guide bar 7b for guiding the hanging position of the prevention member 6 is provided. Here, the “hard fabric” refers to a fabric having a hardness that can be bent by its own weight from the fixing point of the fabric and kept in a state without drooping.

Further, the light leakage prevention member 6 according to the second embodiment can shield external light incident between the mounting frame 2 and the winding pipe 9 and between the mounting surface of the mounting frame 2 and the mounting frame 2. The light leakage prevention member 6 is fixed by a fixing member 7 so that both upper and lower ends are free ends.

That is, the vicinity of the central portion of the light leakage preventing member 6 is sandwiched by the engaging portion 7 a of the fixing member 7 and engaged with the fixed portion 21, and the light leakage preventing member 6 hangs downward from the fixing member 7. The external light incident between the mounting frame 2 and the take-up pipe 9 is shielded and extended upward from the fixing member 7 to shield the external light incident between the mounting frame 2 and its mounting surface. It is like that.

As shown in FIG. 6A, the lower edge portion of the light leakage preventing member 6 according to the second embodiment configured as described above extends from the fixed portion 21 on the front surface of the mounting frame 2 to the guide bar 7b of the fixing member 7. Since it hangs down like this, it is possible to shield external light incident from between the mounting frame 2 and the winding pipe 9. Moreover, since the upper edge part of the light leak prevention member 6 of Example 2 is extended upwards from the fixing member 7, it can shield the external light which injects from between the attachment frame 2 and its attachment surface. it can. And since the light leakage prevention member 6 can be attached and fixed from the front (indoor side) of the roll screen 1, it is excellent in assemblability.

Also in the light leakage prevention member 6 of the second embodiment, the fixing member 7 can be attached to the mounting frame 2 after the bracket 5 is fixed to the mounting surface and the mounting frame 2 is mounted to the bracket 5. The mounting frame 2 can be attached in a state where the bracket 5 is visually recognized at the time of construction, and there is an advantage that the workability when fixing the mounting frame 5 to the bracket 6 is not impaired.

In addition, the light leakage prevention member 6 of the second embodiment is made of a light-shielding hard cloth. However, since the fixing member 7 has the guide bar 7b, the screen 4 is taken up by the take-up pipe 9 and thickened. However, the light leakage prevention member 6 can be bent to follow this thickening. For this reason, regardless of the winding state of the screen 4 by the winding pipe 9, it is possible to shield external light incident between the mounting frame 2 and the winding pipe 9 with high shielding properties.

Alternatively, the light leakage prevention member 6 of the second embodiment is also made of a soft cloth, and separately from the fixing by the fixing member 7, the upper end of the light leakage prevention member 6 is attached to the rear surface of the bracket 5 or attached by attaching means such as a hook-and-loop fastener. It may be fixed to the upper rear surface of the frame 2. In this case, the followability of the drooping of the light leakage preventing member 6 with respect to the thickening by the winding pipe 9 can be further improved.

In the above example, the example in which the light leakage preventing member 6 of Example 2 is attached to the front surface of the mounting frame 2 has been described. However, as shown in FIG. The same action and effect can be obtained also when attaching the light leakage prevention member 6 of No. 2. In this case, it is possible to attach and fix the light leakage prevention member 6 from the back surface (outdoor) of the roll screen 1. Because it can, it is excellent in assemblability.

In addition, the shape of the fixing member 7 for fixing the light leakage prevention member 6 of the second embodiment can be other shapes as shown in FIG. 7 in addition to the examples shown in FIGS. For example, the engaging portion 7a of the fixing member 7 has a substantially C-shaped cross section that can be engaged with the fixed portion 21, as shown in FIG. 7A, or as shown in FIG. 7B. The engaging portion 7a having a substantially cross-sectional shape that can be engaged with the fixed portion 21 can be obtained. Alternatively, in the case where the guide bar 7b is not required to obtain the above-described operation effect depending on the material type of the light leakage prevention member 6, the fixing member 7 is attached to the fixed portion 21 as shown in FIG. Only the engaging portion 7a having a substantially C-shaped cross section that can be engaged is formed, or only the substantially cylindrical engaging portion 7a that can be engaged with the fixed portion 21 as shown in FIG. Can be configured.

As described above, according to the first aspect of the present invention, external light from the gap generated between the winding pipe 9 and the mounting frame 2 is effectively shielded, and preferably the mounting frame 2 and its mounting Since the outside light from the gap generated between the surfaces can be effectively shielded, it is possible to improve the light shielding property during shielding while improving the assembling property.

[Roll screen of the second aspect]
(overall structure)
Next, with reference to FIG. 8 thru | or FIG. 11, the roll screen 1 of the 2nd aspect by this invention is demonstrated. FIG. 8 is a front view showing a schematic configuration of the roll screen 1 according to an embodiment of the second aspect of the present invention. FIG. 9 is a side view illustrating a schematic configuration of the light leakage prevention member 31 of Example 1 in the roll screen 1 according to the embodiment of the second aspect of the present invention. FIGS. 10A and 10B are a side view for explaining the light leakage preventing member 31 of Example 2 and a modification thereof in the roll screen according to the embodiment of the second aspect of the present invention. FIGS. 11A and 11B are side views for explaining the light leakage prevention member 31 in the roll screen 1 of another embodiment of the second aspect according to the present invention and a comparative example thereof. In addition, the same reference number is attached | subjected to the component similar to the roll screen 1 of a 1st aspect.

The roll screen 1 of the second mode shown in FIG. 8 fixes the light leakage prevention member 31 to the winding pipe 9 instead of fixing the light leakage prevention member 6 to the mounting frame 2 like the roll screen 1 of the first mode. In other respects, other configurations and operations can be similar, and thus further details of similar components labeled with the same reference numerals are omitted.

(Light Leakage Prevention Member of Example 1)
First, with reference to FIG. 9, the light leakage prevention member 31 of Example 1 is demonstrated. As shown in FIG. 9, the light leakage prevention member 31 of the first embodiment includes a base end portion 31b extending along the longitudinal direction of the winding pipe 9, and a fin 31a extending from the base end portion 31b so as to be elastically deformable. The base end portion 31 b is fixed to the attachment portion 9 a on the circumferential surface of the winding pipe 9. The fin 31 a is configured to bend along the outer periphery of the winding pipe 9 by winding the screen 4 by the winding pipe 9.

The base end portion 31b is configured as a fabric presser that fixes the end portion of the screen 4 to the winding pipe 9, and the end portion of the screen 4 is engaged with the base end portion 31b by a stapler or the like. And the base end part 31b engages with the attachment part 9a on the surrounding surface of the winding pipe 9, and is fixed.

Further, the fin 31a is long enough to have its tip portion elastically deformed and abutted against the lower surface of the mounting frame 2, and bends to such an extent that the winding of the screen 4 by the winding pipe 9 is not hindered. The length (for example, the length less than the outer periphery of the winding pipe 9) extends from the base end portion 31b.

The light leakage prevention member 31 shown in this example will be described as an example having a substantially V-shaped cross section with the fin 31 a and the base end portion 31 b, but the base end that can be fixed on the peripheral surface of the winding pipe 9. Other cross-sectional shapes (if the fin 31a extends from the base end portion 31b so as to be elastically deformable while shielding the external light incident from the portion 31b and between the mounting frame 2 and the winding means) For example, a substantially inverted T-shape may be used.

In the light leakage prevention member 31 of the first embodiment configured as described above, the fin 31a is wound with the mounting frame 2 at the initial position of the winding of the screen 4 by the winding pipe 9 (that is, the weight bar 8 is the lower limit position). The tips of the fins 31a are elastically deformed and contact the lower surface of the mounting frame 2 so that light leakage between the pipes 9 can be shielded.

When the winding of the screen 4 by the winding pipe 9 is performed, the fins 31a are elastically deformed by the winding pressure of the screen 4 and bend along the outer periphery of the winding pipe 9. The winding of the screen 4 is not hindered.

Further, when the screen 4 is rewound by the winding pipe 9 and the winding pipe 9 reaches the initial position (that is, the weight bar 8 is the lower limit position), the fin 31 a is located between the mounting frame 2 and the winding pipe 9. So that the tip of the fin 31a comes into contact with the lower surface of the mounting frame 2 so that the light leakage can be shielded.

Therefore, the light leakage prevention member 31 according to the first embodiment is configured such that the light between the mounting frame 2 and the winding pipe 9 at the initial position of winding the screen 4 by the winding pipe 9 (that is, the weight bar 8 is the lower limit position). Leakage can be shielded.

Further, since the base end portion 31b of the light leakage preventing member 31 can be fixed on the peripheral surface of the winding pipe 9, the assemblability is excellent.

(Light Leakage Prevention Member of Example 2)
Next, the light leakage prevention member 31 of Example 2 will be described with reference to FIG. As shown in FIG. 10A, the light leakage prevention member 31 of the second embodiment extends from the base end portion 31b so as to be elastically deformable and a base end portion 31b extending along the longitudinal direction of the winding pipe 9. The base end portion 31b is located on a circumferential surface of the winding pipe 9 (or the winding pipe 9) at a position different from the mounting portion of the winding pipe 9 to which one end of the screen 4 is attached. Are attached and fixed by attachment means such as welding, adhesion, or sewing to the screen 4 wound by a predetermined amount. The fin 31 a is configured to bend along the outer periphery of the winding pipe 9 by winding the screen 4 by the winding pipe 9.

Further, the fin 31a is long enough for the end surface of the tip portion to elastically deform and abut against the front surface of the mounting frame 2, and to the extent that the winding of the screen 4 by the winding pipe 9 is not hindered. It extends from the base end portion 31b with a bending length (for example, a length less than the outer periphery of the winding pipe 9).

In the light leakage prevention member 31 shown in this example, an example in which the fin 31a and the base end portion 31b have a substantially V-shaped cross section will be described. However, the base that can be fixed on the peripheral surface of the winding pipe 9 is described. Any other cross-sectional shape can be used as long as it is a fin 31a that shields external light incident from the end 31b and between the mounting frame 2 and the winding means and extends elastically deformable from the base end 31b with the above length. (For example, a substantially inverted T shape) may be used.

In the light leakage prevention member 31 of Example 2 configured as described above, the fin 31a winds up with the mounting frame 2 at the initial position of winding the screen 4 by the winding pipe 9 (that is, the weight bar 8 is the lower limit position). The end surface of the tip portion of the fin 31a is elastically deformed and comes into contact with the front surface of the mounting frame 2 so that light leakage with the pipe 9 can be shielded.

Further, when the screen 4 is rewound by the winding pipe 9 and the winding pipe 9 reaches the initial position (that is, the weight bar 8 is the lower limit position), the fin 31 a is located between the mounting frame 2 and the winding pipe 9. So that the end face of the tip of the fin 31a comes into contact with the lower surface of the mounting frame 2 so that the light leakage can be shielded.

Accordingly, the light leakage prevention member 31 of the second embodiment is configured so that the light between the mounting frame 2 and the winding pipe 9 is at the initial position of winding the screen 4 by the winding pipe 9 (that is, the weight bar 8 is the lower limit position). Leakage can be shielded.

Further, as shown in FIG. 10B, the length of the fin 31a is shorter than the end face of the front end portion of the fin 31a being elastically deformed and brought into contact with the front surface of the mounting frame 2, and the screen by the winding pipe 9 is used. 4 is configured to extend from the base end portion 31b with a length that does not hinder winding of the wire 4, and a shielding fabric 32 made of a shielding hard fabric is attached to the fin 31a by a staple or the like. The end surface of the front end portion of the shielding fabric 32 engaged with 31a can be configured to have a length sufficient to contact the front surface of the mounting frame 2.

In this case, the end surface of the front end portion of the shielding fabric 32 engaged with the fin 31a may be configured to have a length sufficient to contact the front surface of the bracket 5 (or the front end portion of the shielding fabric 32 to the mounting surface). In this way, it is possible to shield not only between the attachment frame 2 and the take-up pipe 9 but also external light incident from between the attachment surface of the attachment frame 2 and the attachment frame 2.

(Roll screen with cover)
As shown in FIG. 11 (a), as one embodiment of the roll screen 1, the rear cover 51 attached to the wall surface and the rear cover 51 are fitted to accommodate the mounting frame 2 and the winding pipe 9. The front cover 52 may be further provided. In this case, the light leakage prevention member 31 has a length that allows the fin 31 to elastically deform and come into contact with any one of the upper surface side inner wall 52a, the front surface side inner wall 52b, and the bottom surface side inner wall 52c of the front cover 52. It can be configured to extend from the base end portion 31b with a length that does not hinder the winding of the screen 4 by the take-up pipe 9 (for example, a length less than the outer periphery of the take-up pipe 9).

In this case, the base end portion 31b is on the peripheral surface of the winding pipe 9 (or alternatively, at a position different from the mounting portion of the winding pipe 9 to which one end of the screen 4 is attached, as in the above-described embodiments. It can be fixed by being attached to the screen 4 wound by a predetermined amount by the take-up pipe 9) by attaching means such as welding, bonding or sewing.

By configuring in this way, it is possible to configure to be able to shield the leaked light that wraps around between the front cover 52 and the winding pipe 9.

That is, as in the comparative example shown in FIG. 11B, in the roll screen 1 having the front cover 52, the outside light reflected by the screen 4 is reflected inside the front cover 52 and leaked into the indoor side. May be. Even in the roll screen 1 having such a front cover 52, the light leakage prevention member 31 as shown in FIG. 11A is provided on the winding pipe 9, so that the winding pipe 9, the mounting frame 2, and the like. It is possible to effectively shield the external light from the gap generated between the two, and improve the assembling property while improving the light shielding property at the time of shielding.

[Roll screen of the third aspect]
(overall structure)
FIG. 12 is a front view partially showing a schematic configuration of the roll screen 1 according to an embodiment of the third aspect of the present invention. FIG. 13 is a side view showing the operation of the light leakage prevention member 6 in the roll screen 1. FIG. FIG. 14 shows a detailed configuration of the light leakage prevention member 6 shown in FIG. In addition, the same reference number is attached | subjected to the component similar to the roll screen 1 of the 1st aspect mentioned above.

In the example of the roll screen 1 of the first aspect shown in FIG. 1, the light leakage prevention member 6 is fixed to the mounting frame 2 using the fixing member 7, but the roll screen 1 of the third aspect shown in FIG. Then, the light leakage prevention member 6 is different in that it is composed of a synthetic resin substrate 61 having a predetermined strength and an auxiliary sheet 62 attached to the substrate 61.

In particular, in the roll screen 1 of the third aspect shown in FIG. 12, the light leakage prevention member 6 is pivotally supported with respect to the support groove 20 of the mounting frame 2 and covers at least a part of the operation pulley 10. It is also different in that the design is improved by this. Since other configurations and operations can be similar, further details of similar components labeled with the same reference numerals are omitted.

That is, in the roll screen 1 shown in FIG. 12, the light leakage prevention member 6 has a substantially L-shaped cross section as a whole as shown in FIGS. 13 and 14, and its shaft portion 61 a is the mounting frame 2. It is pivotally supported so as to be rotatable with respect to a support groove 20 provided on the front side (inside the room). Then, as shown in FIG. 13, the screen 4 is suspended from the back side (outdoor side) of the winding pipe 9.

Further, when the light leakage prevention member 6 is provided so as to cover at least a part of the operation pulley 10, for example, from the non-operation state shown in FIG. 13 (a), the operation cord 3 is moved to the front as shown in FIG. 13 (b). By pulling the side (indoor side) at an angle, when the screen 4 is wound up by the winding pipe 9, the operation cord 3 comes into contact with the curved raised portion 61b of the light leakage prevention member 6 to prevent light leakage. The member 6 rotates so that the pulling operation is not hindered.

Further, since the curved raised portion 61b of the light leakage preventing member 6 has a shape raised to the curved shape, the frictional resistance can be reduced even if the operation cord 3 comes into contact with the curved portion. The load required for operation is not greatly increased. In addition to the braid, the operation cord 3 includes a ball chain in which a large number of balls are fixed to the string and a metal chain in which a plurality of balls are connected.

When the screen 4 taken up by the take-up pipe 9 reaches a predetermined winding diameter by the pulling operation, the operation cord 3 does not come into contact with the light leakage prevention member 6, and the light leakage prevention member 6 takes up the winding of the screen 4. Therefore, the function of the light leakage prevention member 6 and its operability are not hindered.

As described above, in the roll screen 1 shown in FIGS. 12 and 13, the light leakage prevention member 6 can improve the design, and the light shielding function can be applied without greatly increasing the load required for the pulling operation.

Then, the light leakage prevention member 6 shown in FIG. 13 is rotatably supported by sliding the shaft portion 61a from the left and right direction and inserting it into the support groove 20 of the mounting frame 2. For this reason, the support groove 20 of the mounting frame 2 is formed in a substantially C-shaped cross section extending in the longitudinal direction of the mounting frame 2, and when the shaft portion 61 a is inserted, the shaft portion 61 a of the light leakage prevention member 6 is The pivoting operation grips the mounting frame 2 so that it does not come off from the support groove 20.

support members

2a and 2b, so that the side cover is inserted after the shaft portion 61a of the light leakage preventing member 6 is inserted into the mounting frame 2. Thus, the notches of the

support members

2a and 2b can be concealed and a function of preventing the movement of the shaft portion 61a in the light leakage preventing member 6 in the left-right direction can be provided.

In particular, the design can be improved by configuring the screen 4 and the auxiliary sheet 62 with the same decorative surface material.

The shaft portion 61 a is a portion that is pivotally supported by the support groove 20. The curved raised portion 61 b is a portion that is brought into contact with or close to the screen 4 that is wound or unwound by the winding pipe 9. The shielding part 61 c is a part that prevents light leakage caused by a gap between the mounting frame 2 and the winding pipe 9. The portion 61f extending in a curved shape from the curved raised portion 61b is formed when the screen 4 is suspended from the indoor side (or when the curved raised portion 61b is installed on the outdoor side with respect to the screen 4 suspended from the indoor side. ) Is a part that alleviates interference when the weight bar 8 provided at the lower end of the screen 4 rises and collides, and it is not always necessary to install the light leakage prevention member 6 on the front side as in this example. There is no need to provide 61f.

The light leakage prevention member 6 is weight balanced so as to increase the amount of proximity between the curved raised portion 61b and the screen 4 in order to prevent light leakage when the screen 4 is fully closed.

The shaft portion 61a of the light leakage prevention member 6 is pivotally supported by the support groove 20, and is formed in a substantially C-shaped cross section as a whole. The support groove 20 forms a bent shaft 20 f at the tip of the rotation restricting piece 20 a extending upward from the bottom of the mounting frame 2, and can support the shaft portion 61 a of the light leakage prevention member 6. The tip of the shaft portion 61a is formed in a substantially T-shaped cross-section, and is engaged with the support groove 20 with a spatial margin so that the light leakage prevention member 6 is not easily detached from the support groove 20. The degree of freedom of rotation of the light leakage prevention member 6 is increased. The shape related to the shaft support by the shaft portion 61a and the support groove 20 is not limited to this, and one of them may be a round shaft and the other may be a shape that holds the round shaft. it can. In addition to directly suspending the shaft portion 61a from the mounting frame 2, the shaft portion 61a is pivotally supported with respect to the

The leakage prevention member 6 can be rotated. As described above with reference to FIG. 13B, the curved raised portion 61 b can also contact the operation cord 3.

The shielding portion 61c is a portion between the shaft portion 61a and the curved raised portion 61b, and is formed with a length that prevents light leakage generated from a gap between the mounting frame 2 and the winding pipe 9. On the indoor side surface of the shielding portion 61 c of the substrate 61, an auxiliary sheet 62 such as a fabric decorated to enhance the design of the substrate 61 is attached. Further, as shown in FIG. 14, it is preferable to provide an upper protrusion 61 d on the indoor side surface at the upper end of the shielding part 61 c, thereby facilitating positioning related to attachment of the auxiliary sheet 62 to the substrate 61. become. Such an auxiliary sheet 62 can be polymerized to the substrate 61 by adhesion, welding, or the like. As a result, the auxiliary sheet 62 is maintained in the shape of the surface along the surface of the substrate 61, and can also reinforce or protect the substrate 61.

As shown in FIG. 14, the light leakage prevention member 6 is configured by adhering the auxiliary sheet 62 to the substrate 61 made of a synthetic resin having a predetermined strength so as to be attached. Rather than being configured to suspend with shielding fabric such as the light leakage prevention member 6 of the first aspect described above, the surface shape can be maintained without being affected by warpage, undulation, etc. of the auxiliary sheet 62 itself, Wind fluctuations can also be reduced.

Further, the upper protrusion 61d can have a function of restricting the upward rotation of the light leakage prevention member 6, and can be brought into contact with the rotation restriction piece 20b of the mounting frame 2 so as to prevent the light leakage prevention member. The rotation range of 6 can be restricted. Further, as shown in FIG. 14, a lower protrusion 61e for restricting the downward rotation of the light leakage prevention member 6 is provided on the outdoor side surface at the upper end of the shielding part 61c, and the rotation restricting piece 20a of the support groove 20 is provided. You may comprise so that it can contact | abut. Although it is not necessary to provide the lower protrusion 61e, it is desired to reduce the contact pressure with the screen 4 (or non-contact) and suppress damage to the screen 4 due to friction when the screen 4 moves up and down, and the contact sound. Sometimes it becomes effective.

The light leakage prevention member 6 configured as described above can easily assemble, and can effectively shield light leakage from a gap generated between the winding pipe 9 and the mounting frame 2. And, the rotation function of the light leakage prevention member 6 keeps the smoothness of the rotation operation and rotates following the increase / decrease of the winding diameter of the winding pipe 9, so that it corresponds to various winding diameters. In addition, light leakage can be reduced while downsizing.

On the other hand, a support groove 20 is provided in the intermediate portion in the vertical direction so that the shaft portion 61a provided at one end of the substrate 61 can be inserted and supported, and the substrate 61 is disposed below the support groove 20 in the mounting frame 2 in front or rear view. It is possible to prevent light leakage while improving its design properties.

(Modification of light leakage prevention member)
FIGS. 15A and 15B are side views schematically showing the configuration of a modification of the light leakage prevention member 6 in the roll screen 1 according to the embodiment of the third aspect of the present invention. The light leakage prevention member 6 shown in FIG. 15 (a) is also composed of a synthetic resin substrate 61 having a predetermined strength and an auxiliary sheet 62 such as a fabric decorated so as to enhance its design. The substrate 61 is different from the example shown in FIG. 14 in that the substrate 61 has a groove 61g, and the auxiliary sheet 62 is attached by engaging with the groove 61g.

That is, in the light leakage prevention member 6 shown in FIG. 15A, the substrate 61 is mainly composed of the shaft portion 61a and the shielding portion 61c, and the shielding portion 61c is wound by the winding pipe 9 on the outdoor side surface. Alternatively, it forms a portion that is brought into contact with or close to the screen 4 to be rewound, and has a length that prevents light leakage caused by a gap between the mounting frame 2 and the winding pipe 9.

And the groove part 61g is formed in the upper end and lower end of the shielding part 61c by the

protrusion parts

61h and 61j which protrude in the substantially side cross-sectional shape on the indoor side surface, respectively. The light leakage prevention member 6 is configured by engaging an auxiliary sheet 62 such as a hard cloth with the groove 61g. Even with the light leakage prevention member 6 configured as described above, the same actions and effects as those of the light leakage prevention member 6 shown in FIG. 14 can be obtained.

In FIG. 15A, instead of providing the protrusion 61h, the upper end of the auxiliary sheet 62 is attached to the indoor side surface of the upper end of the shielding part 61c by bonding or the like, and only the lower end of the auxiliary sheet 62 is engaged by the protrusion 61j. The lower end of the auxiliary sheet 62 is attached to the indoor side surface of the lower end of the shielding part 61c by bonding or the like instead of providing the protruding part 61j, and only the upper end of the auxiliary sheet 62 is engaged by the protruding part 61h.

[Roll screen of the fourth aspect]
(overall structure)
The schematic configuration of the roll screen 1 according to an embodiment of the fourth aspect of the present invention is substantially the same as the schematic configuration in the third aspect described above (a front view partially shown in FIG. 12). The shape of 6 is different. FIGS. 16A and 16B are side views showing the configuration and operation of the light leakage prevention member 6 in the roll screen 1 according to the embodiment of the fourth aspect of the present invention. In addition, the same reference number is attached | subjected to the component similar to the roll screen 1 of the 3rd aspect mentioned above.

That is, in the roll screen 1 of the fourth aspect shown in FIG. 16, the light leakage prevention member 6 is attached to the synthetic resin substrate 61 having a predetermined strength and the substrate 61 as a decorative surface material. The point constituted by the sheet 62 and the light leakage prevention member 6 are pivotally supported with respect to the support groove 20 of the mounting frame 2 and are provided so as to cover at least a part of the operation pulley 10. However, as described in detail later, the substrate 61 is different in that it has a shape that improves its functionality. Since other configurations and operations can be similar, further details of similar components labeled with the same reference numerals are omitted.

In particular, in the roll screen 1 of the fourth aspect, as shown in FIG. 16, the light leakage prevention member 6 has a substantially inverted L-shaped cross section as a whole, and is excellent in space saving and design required for installation. The shape is excellent in adaptability to the winding pipe 9 having an arbitrary diameter. The shaft portion 61 a of the light leakage prevention member 6 is pivotally supported with respect to the support groove 20 provided on the front side (inside the room) of the mounting frame 2, and the screen 4 is on the back side of the winding pipe 9.

The light leakage prevention member 6 comes into contact with the curved raised portion 61b of the leakage prevention member 6 and does not hinder the pulling operation.

Further, when the screen 4 taken up by the take-up pipe 9 by the pulling operation reaches a predetermined take-up diameter, the screen 4 comes into contact with the shielding portion 61c in the light leakage preventing member 6, so that the operation cord 3 is provided with the light leakage preventing member 6. Since the light leakage prevention member 6 rotates according to the winding of the screen 4, the function of the light leakage prevention member 6 and its operability are not hindered.

Thus, also in the roll screen 1 of the fourth aspect shown in FIG. 16, the load required for the pulling operation is not greatly increased while improving the design by the light leakage prevention member 6 as in the third aspect. A light blocking function can be applied.

And the light leakage prevention member 6 shown in FIG. 16 is rotatably supported by sliding the shaft portion 61a from the left and right direction and inserting it into the support groove 20 of the mounting frame 2. For this reason, the support groove 20 of the mounting frame 2 is formed in a substantially C-shaped cross section extending in the longitudinal direction of the mounting frame 2, and when the shaft portion 61 a is inserted, the shaft portion 61 a of the light leakage prevention member 6 is The pivoting operation grips the mounting frame 2 so that it does not come off from the support groove 20.

Further, the

support members

(Light leakage prevention member)
Here, a detailed configuration of the light leakage prevention member 6 shown in FIG. 16 will be described with reference to FIGS. 17 and 18. FIG. 17 is a perspective view for explaining a method of attaching a cloth (auxiliary sheet) of a light leakage prevention member in a roll screen according to an embodiment of the fourth aspect of the present invention. 18 (a) and 18 (b) are enlarged views for explaining a method for attaching the fabric (auxiliary sheet) of the light leakage preventing member in the roll screen according to the embodiment of the fourth aspect of the present invention. is there.

In the roll screen 1 of the fourth aspect, as shown in FIG. 16, the light leakage prevention member 6 has a substantially inverted L-shaped cross-sectional shape as a whole, and further, a synthetic resin substrate 61 having a predetermined strength. And an auxiliary sheet 62 such as a cloth attached to the substrate 61 and decorated to enhance its design. The substrate 61 mainly includes a shaft portion 61a, a curved raised portion 61b, and a shielding portion 61c, and is suspended directly (or indirectly as described later) from the mounting frame. The light leakage prevention member 6 can be configured by providing the light leakage prevention function to one or both of the substrate 61 and the auxiliary sheet 62. Further, the auxiliary sheet 62 can have a function of reinforcing or protecting the substrate 61.

The shaft portion 61 a is a portion that is pivotally supported by the support groove 20. The curved raised portion 61b is a raised portion for efficiently shielding light by limiting the incident angle of light leakage from the outside. The shielding part 61 c is a part that prevents light leakage caused by a gap between the mounting frame 2 and the winding pipe 9.

The light leakage prevention member 6 is provided with a lower protrusion 61e below the shaft portion 61a to regulate the rotation of the light leakage prevention member 6 to the outdoor side to achieve a weight balance.

The shaft portion 61a of the light leakage prevention member 6 is pivotally supported by the support groove 20, and is formed in a substantially C-shaped cross section as a whole. The tip of the shaft portion 61a is formed in a substantially T-shaped cross-section, and is engaged with the support groove 20 with a spatial margin so that the light leakage prevention member 6 is not easily detached from the support groove 20. The degree of freedom of rotation of the light leakage prevention member 6 is increased. The shape related to the shaft support by the shaft portion 61a and the support groove 20 is not limited to this, and one of them may be a round shaft and the other may be a shape that holds the round shaft. it can. In addition to directly suspending the shaft portion 61a from the mounting frame 2, the shaft portion 61a is pivotally supported with respect to the

support members

The curved raised portion 61b is a raised portion for efficiently shielding light by limiting the incident angle of light leakage from the outside. As described above with reference to FIG. 16B, the curved raised portion 61b is operated. The cord 3 can also be contacted.

The shielding portion 61c is a portion between the shaft portion 61a and the curved raised portion 61b, and is formed with a length that prevents light leakage generated from a gap between the mounting frame 2 and the winding pipe 9. On the indoor side surface of the shielding portion 61 c of the substrate 61, an auxiliary sheet 62 such as a fabric decorated to enhance the design of the substrate 61 is attached.

As shown in FIG. 17, the light leakage prevention member 6 is configured by inserting and engaging an auxiliary sheet 62 such as a hard cloth in the groove 61 g from the left and right directions. In particular, regarding the view A shown in FIG. 17, as shown in FIG. 18A, the protrusion 61 h (similar to the protrusion 61 j) is formed with a gap narrower than the cloth thickness of the auxiliary sheet 62 such as cloth. When the auxiliary sheet 62 is inserted and engaged with the groove 61g from the left and right directions, the auxiliary sheet 62 is sandwiched and held, that is, can be held and fixed. Therefore, the auxiliary sheet 62 can be easily replaced, and the substrate 61 can be applied to various types of roll screens 1. As a result, it is excellent in terms of convenience and cost reduction. In addition, since the

protrusions

61h and 61j also function as positioning portions related to the attachment of the auxiliary sheet 62, the light leakage prevention member 6 is easy to attach, except when it is intentionally removed. Even if it rotates, the auxiliary sheet 62 has a structure that does not easily fall off.

That is, instead of providing the

protrusions

61h and 61j, it is easier to replace the auxiliary sheet 62 than to attach or attach the auxiliary sheet 62 to the indoor side surface of the shielding part 61c by hook-and-loop fastener or adhesion. It is also advantageous to apply 61 to various types of roll screens 1.

Further, as shown in FIG. 16, the light leakage prevention member 6 is configured by attaching the auxiliary sheet 62 to the substrate 61 made of a synthetic resin having a predetermined strength so as to adhere to the substrate 61, and the like.

Designability is improved.

And the light leakage prevention member 6 comprised in this way can be installed with respect to both an indoor side and an outdoor side, and as shown in FIG. On the other hand, a support groove 20 is provided in the intermediate portion in the vertical direction so that the shaft portion 61a provided at one end of the substrate 61 can be inserted and supported. It is possible to prevent light leakage while improving its design properties.

In the fourth aspect, as described with reference to FIG. 15, it is also possible to adopt a form in which the auxiliary sheet 62 such as a cloth is sandwiched and held only on the upper and lower ends of the substrate 61 and fixed. . Therefore, the light leakage prevention member 6 in the fourth aspect can be configured to be slid and inserted from the up and down direction, in addition to the auxiliary sheet 62 such as the fabric being slid from the left and right direction.

Since the light leakage prevention member 6 in the fourth aspect has a structure that can be easily applied to a shielding device having a frame such as a head box such as a horizontal blind or a lifting curtain in addition to the roll screen 1. It is also excellent in terms of convenience and cost reduction. For example, the light leakage prevention member 6 according to the fourth aspect can be applied to an application for shielding between the uppermost slat of the horizontal blind and the head box.

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. For example, in each embodiment, the roll screen 1 that mainly supports the screen 4 in a suspended manner has been described. However, the light leakage prevention according to the present invention can be applied to a shielding device that supports a double shielding material in a suspended manner. A member can be applied. As an example of this, for example, in order to suspend and support the double screen for the roll screen 1 of each aspect described above, the screen 4 is suspended from the winding pipe 9 and folded on the mounting frame 2. An attachment means for attaching and supporting the other end by hanging is provided, and the screen 4 can be suspended and supported by the attachment means and the winding pipe 9 as a double screen.

According to the present invention, it is possible to effectively shield external light from the gap generated between the winding means and the mounting frame, and to improve the light-shielding property at the time of shielding while improving its assembling property. It is useful for the application of the shielding apparatus of the form.
