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

(overall structure)
First, with reference to FIG.1 and FIG.2, the structure of the roll screen 1 as a shielding apparatus of one Embodiment by this invention is demonstrated. FIG. 1 is a front view showing a schematic configuration of a roll screen 1 according to the present invention, and FIG. 2 is a side perspective view of the roll screen 1 according to the present invention.

  In the roll screen 1 shown in FIG. 1, support members 2 a and 2 b are fixed to both ends of the mounting frame 2, and a shaft member 11 is fixed to the support members 2 a and 2 b, and a fixed shaft ( The cylindrical winding pipe 3 is rotatably supported between the support members 2a and 2b. The mounting frame 2 is fixed to the attachment surface by a bracket 6. Each of the support members 2a and 2b is accommodated by the side cover 10 and, as will be described later, improves its design and functionality related to the rotation operation of the light shielding fins 9.

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

  The winding pipe 3 is attached to one end of the screen 4 and supports the screen 4 so that the screen 4 can be wound or unwound. The other end of the screen 4 is attached to a weight bar 5 that functions as a weight member. Accordingly, the screen 4 is stretched based on the weight of the weight bar 5. In the example of the present embodiment, the screen 4 is suspended from the outdoor side of the winding pipe 3 (see FIG. 2).

  When the operation cord 7 is operated to rotate the winding pipe 3 in the screen winding direction, the weight bar 5 is raised, and when the winding pipe 3 is rotated in the screen unwinding direction, the weight bar 5 is lowered. The movement restricting member 12 can be mounted on the operation cord 7 formed of a ball chain, and the movement restricting member 12 can be brought into contact with the operation pulley 8 or the like to stop its rotation. The upper limit position of the bar 5 may be determined.

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

  Here, in the roll screen 1 according to the present invention, the light shielding fin 9 having a structure that allows the predetermined fabric 13 to be easily attached is attached to the front side (front side) of the mounting frame 2, and the winding pipe 3 Light leakage from the gap generated between the mounting frame 2 and the mounting frame 2 is effectively shielded. As shown in FIG. 2, although details will be described later, the shaft portion 91 of the light shielding fin 9 is engaged with the bearing portion 20 provided on the front side of the mounting frame 2. It is supported on the front side (front side) of the frame 2 so as to be rotatable within a predetermined range. Hereinafter, the light shielding fin 9 of one embodiment will be described in detail.

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

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

  The width in the left-right direction of the light-shielding fin 9 is slightly shorter than the width in the left-right direction of the mounting frame 2. For example, when the light-shielding fin 9 is made of synthetic resin, the width in the left-right direction due to thermal expansion or the like. Even if it changes, it is locked so that it can rotate smoothly.

  A bearing portion 20 having a substantially C-shaped cross section extending in the longitudinal direction is formed below the front surface of the mounting frame 2. The shaft portion 91 of the light shielding fin 9 is engaged with the bearing portion 20, whereby the light shielding fin 9 is rotatably supported on the back side of the mounting frame 2. Support members 2 a and 2 b are attached to both ends of the mounting frame 2 in the longitudinal direction.

  The support members 2a and 2b have the same shape, and as shown in FIG. 4, a notch 23 having a size that substantially matches the substantially C-shaped cross-sectional shape of the bearing portion 20 of the mounting frame 2 is provided. . The notches 23 are provided so that the shaft portions 91 of the light shielding fins 9 can be slid from the left and right directions and inserted into the bearing portions 20 to be supported after the support members 2a and 2b are fixed to the mounting frame 2. ing. Then, the light shielding fins 9 are slidable to be removable, and other than this slide is not removable, and even if an external force is applied to the light shielding fins 9, the light shielding fins 9 are not detached from the mounting frame 2.

  Further, the support members 2a and 2b have screw holes 21 for fixing the mounting frame 2 using mounting screws, and shaft members 11 having a fixed shaft (not shown) for rotatably supporting the winding pipe 3. Screw holes 22 for fixing (see FIG. 1) are provided at a plurality of locations. That is, even after the support members 2a and 2b are fixed to the mounting frame 2 in a state in which the winding pipe 3 is supported by the support members 2a and 2b, the shaft portion 91 of the light shielding fin 9 is slid from the left and right directions to thereby obtain the bearing portion 20. It can be inserted and supported. For this reason, it is easy to attach the light shielding fins 9.

  The side cover 10 is attached from the viewpoint of improving the design so that the mounting screws of the screw holes 21 and 22 of the support members 2a and 2b cannot be visually recognized from the outside. There is also an effect of improving the functionality related to the rotation operation of the light shielding fins 9.

  That is, the side cover 10 is provided with a wall having a height so as to regulate the positions of both ends of the light shielding fin 9 in the left-right direction within the rotation range of the light shielding fin 9 so that the light shielding fin 9 can be smoothly rotated. Part 10a is formed. The height of the wall 10a is sufficiently high to accommodate the thickness of the support members 2a and 2b. The side cover 10 is made of synthetic resin and can be attached with a narrow pressure following the outer shape of the support members 2a and 2b formed of a metal material. An inwardly projecting claw portion 10b is formed. Thereby, regarding the rotation operation of the light shielding fin 9, the wall portion 10a has a height so that the claw portion 10b and the notch 23 do not hinder the rotation operation.

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

  As shown in FIG. 3, a bearing portion 20 having a substantially C-shaped cross section extending in the longitudinal direction is formed below the front surface of the mounting frame 2. More specifically, the bearing portion 20 forms a bent shaft 20f at the tip of a rotation restricting piece 20a extending upward from the bottom portion of the mounting frame 2 so that the shaft portion 91 of the light shielding fin 9 can be supported. The rotation restricting piece 20 a has a function of restricting the downward rotation of the light shielding fin 9. In addition, a rotation restricting piece 20 b that restricts the upward rotation of the light shielding fin 9 is formed above the bearing portion 20 on the back surface of the mounting frame 2. In the illustrated example, the rotation restricting piece 20a is formed in a substantially C shape protruding forward from the front surface of the main body of the mounting frame 2, and the rotation restricting piece 20b is formed in a substantially plate shape protruding backward. In the state where the shaft portion 91 of the light shielding fin 9 is locked to the bearing portion 20, the rotation of the light shielding fin 9 in the vertical direction is restricted, and no matter how the light shielding fin 9 is rotated, the rearward direction. The outer bearing portion 20 is prevented from being detached.

  The light shielding fin 9 has, as a schematic configuration, a support plate portion 93 having a substantially C-shaped shaft portion 91 at the tip and protruding forward from the front side surface of the mounting frame 2 with a length a, and the support plate. The shielding plate portion 94 extending downward from the portion 93 with a length b has a substantially L-shaped cross-sectional shape as a whole, and has a double curved surface shape so as to avoid or mitigate collision force and contact sound due to interference with the screen 4. These members (which may be a single member or a decoding member) are formed.

  More specifically, the support plate portion 93 has a shape that is bent substantially in an L shape, and a substantially C-shaped shaft portion 91 is formed at the tip thereof. The shaft portion 91 is a portion that is rotatably locked by the bending shaft 20f in the bearing portion 20. The tip of the shaft portion 91 is formed in a substantially bowl shape that is refracted at an acute angle, and is engaged with the bearing portion 20 in a state having a spatial margin so that the light shielding fins 9 are not easily detached from the bearing portion 20. The degree of freedom of rotation of the light shielding fin 9 is increased.

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

  A contact portion 97 is formed in the vicinity of the base of the shaft portion 91 provided at the tip of the support plate portion 93. Although the details will be described later, the abutting portion 97 is a portion that regulates the upward rotation of the light shielding fin 9 by abutting against the rotation restricting piece 20b.

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

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

  A curved interference mitigation portion 95 is formed at the lower end of the shielding plate portion 94 extending downward from the support plate portion 93. Even when there is contact with the screen 4, the interference relaxation unit 95 has a shape that warps in a direction away from the screen 4 so as to relieve the contact sound and collision force.

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

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

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

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

(Operation of shading fin)
FIGS. 6A, 6 </ b> B, and 6 </ b> C are side views for individually explaining an operation example of the light shielding fin 9 of one example in the roll screen 1 of the present embodiment.

  As shown in FIG. 6A, the light-shielding fin 9 of this embodiment includes a support plate portion 93 that is bent and protrudes forward from the front side surface of the mounting frame 2 with a length a, and downward from the support plate portion 93. Due to the shielding plate portion 94 extending in the length b, the whole has a substantially L-shaped cross-sectional shape.

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

  As shown in FIG. 6B, when the light shielding fin 9 of this embodiment is applied to a roll screen 1 having a relatively small maximum winding diameter S of the screen 4, the screen 4 and the light shielding fin 9 are provided. As a basic posture, there is no contact, and the light shielding fins 9 are shielded from light while maintaining the longitudinal direction of the shielding plate portion 94 substantially perpendicular to the front-rear direction of the mounting frame 2 (a state in which they are suspended in the vertical direction). The function can be retained.

  On the other hand, as shown in FIG. 6C, when the light shielding fin 9 of this embodiment is applied to a roll screen 1 having a relatively large maximum winding diameter S of the screen 4, the screen 4 and the light shielding fin 9 are Even in the case of contact, the light shielding fin 9 can be rotated following the winding thickness of the screen 4, and the light shielding function can be maintained.

  Further, as shown in FIG. 7, when the mounting frame 2 is applied to the mounting surface with a predetermined inclination angle α through the bracket 6, the light shielding fin 9 that is locked to the locking portion 20 is the predetermined predetermined angle. And a predetermined distance d or more as a distance at the time of maximum proximity to the mounting surface. The predetermined inclination angle is assumed to be not less than 0 degrees and not more than 30 degrees from the vertical direction. Thereby, also in the roll screen 1 using the light shielding fin 9, it can construct without impairing the quality.

  In the example shown in FIG. 7, the light shielding fin 9 is in contact with the screen 4 wound up with the maximum diameter, but this is the maximum outer diameter that can be taken with various roll screens 1. In this case, the light shielding fin 9 is inclined corresponding to the predetermined inclination angle α, and the distance at the time of maximum proximity to the mounting surface is maintained at a predetermined distance d or more. Yes.

  For example, when the light shielding fin 9 does not come into contact with the screen 4 wound with the maximum diameter, the margin for the effectiveness becomes larger, and the inclination of the light shielding fin 9 will be described with reference to FIG. As described above, since the downward movement of the light shielding fin 9 is restricted at the position where the projection 98 provided on the light shielding fin 9 contacts the rotation restricting piece 20a of the bearing portion 20 in the mounting frame 2, the light shielding fin 9 Can maintain its quality without colliding with the screen 4 or the like.

  Further, when the mounting frame 2 is applied to the mounting surface at a predetermined inclination angle α via the bracket 6 on the roll screen 1 of the screen 4 in which the light shielding fin 9 is wound with the maximum diameter, FIG. As shown in the drawing, the distance at the maximum proximity to the mounting surface is maintained at a predetermined distance d ′ or more so that the light shielding fin 9 does not collide with the mounting surface even if the light shielding fin 9 flutters at the rotation angle β regulated from the state. It is supposed to be. That is, as described with reference to FIG. 5B, the light shielding fin 9 is formed with the contact portion 97, and the light shielding fin 9 comes into contact with the rotation restricting piece 20 b in the mounting frame 2. 9 is restricted from turning upward. And the contact part 97 of this light-shielding fin 9 is comprised so that the movable range of the light-shielding fin 9 may be regulated taking into consideration the time of construction requiring the predetermined inclination angle α.

  The present invention has been described above with reference to specific embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the technical concept thereof. In particular, the shape and structure of the shaft portion 91 of the light shielding fin 9 and the method of locking are only described as examples. For example, the shaft portion 91 of the light shielding fin 9 may be formed by a round shaft or the like. Instead of the mounting frame 2, the support members 2 a and 2 b can be used as the frame body that supports the shaft portion 91 of the fin 9.
