  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. Moreover, in the example demonstrated below, the side to visually recognize is made into the front side (or indoor side) with respect to the front view of the roll screen 1 shown in FIG. 1, and the other side is made into the back side (or outdoor side).

(overall structure)
First, with reference to FIG. 1, 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.

  In the roll screen 1 shown in FIG. 1, support members 2a and 2b are fixed to both ends of the mounting frame 2, and shaft members (not shown) are fixed to the support members 2a and 2b, and extend from the shaft members. A cylindrical winding pipe 3 is rotatably supported between the support members 2a and 2b by a fixed shaft (not shown). The mounting frame 2 is fixed to a ceiling surface or a wall mounting surface by a bracket 6. The support members 2a and 2b are respectively covered with side covers 10a and 10b (collectively referred to as “side covers 10”), and in particular, improve the design when viewed from the side as described later.

  An operation pulley (not shown) is provided at the right end portion of the winding pipe 3, and an endless operation cord 7 hung on the operation pulley is suspended. In this example, the operation cord 7 is formed of a ball chain, and the surface of the operation pulley around which the ball chain is hung is configured 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 may be formed in a string shape, and the surface of the operation pulley 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 this embodiment, the screen 4 is suspended from the outdoor side of the winding pipe 3.

  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.

  In this example, in the winding pipe 3, a spring motor that reduces the operating force when the screen 4 is wound is housed on the left end side, and a stopper device that prevents the screen 4 from dropping its own weight is housed on the right end side. (Not shown).

  Here, in the roll screen 1 according to the present invention, the fin 9 having a structure capable of easily attaching the predetermined fabric 13 is attached to the front side (front side) of the mounting frame 2, and the winding pipe 3 and Light leakage from a gap generated between the mounting frame 2 and the like is effectively shielded.

(Fin configuration)
In FIG. 2, the structure of the fin 9 of one Example in the roll screen 1 of this embodiment is shown. As shown in FIG. 2, the shaft portion 91 of the fin 9 is engaged with the bearing portion 20 provided on the front side of the mounting frame 2, whereby the fin 9 is connected to the front side (front side) of the mounting frame 2. And is supported rotatably within a predetermined range.

  The 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 fins 9 are preferably formed of a synthetic resin with 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 lateral width of the fin 9 has substantially the same length as the lateral width of the mounting frame 2, and more precisely is slightly shorter than the lateral width of the mounting frame 2. Even if the lateral width changes due to thermal expansion or the like when the fins 9 are made of synthetic resin, the fins 9 are locked so as to be smoothly rotatable.

  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 fin 9 is engaged with the bearing portion 20, whereby the 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 are provided with notches (not shown) having a size that substantially matches the substantially C-shaped cross-sectional shape of the bearing portion 20 of the mounting frame 2. The notches are provided so that the shaft portions 91 of the 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. Then, the fin 9 is slid to be removable, and other than this slide is not removable, and even if an external force is applied to the fin 9, the fin 9 is not detached from the mounting frame 2.

  However, in the roll screen 1 of the present embodiment, the support members 2a and 2b are covered with the side covers 10a and 10b, respectively. For this reason, the side covers 10 a and 10 b have a function of restricting the position of the fin 9 by suppressing the sliding of the fin 9 in the left-right direction even when the fin 9 is rotated.

  As shown in FIG. 2, 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 bending 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 fin 9 can be supported. The rotation restricting piece 20 a has a function of restricting the downward rotation of the fin 9. Further, a rotation restricting piece 20 b for restricting the upward rotation of the 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 fin 9 is locked to the bearing portion 20, the rotation of the fin 9 in the vertical direction is restricted, and no matter how the fin 9 is rotated, the bearing portion is moved back. It is designed not to deviate from 20.

  The 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 predetermined length, and the support plate portion. A shielding plate portion 94 extending downward from 93 with a predetermined length has a substantially L-shaped cross-sectional shape as a whole, and avoids collision force and contact sound caused by interference with the screen 4 (or a weight bar 5 described later). Alternatively, it is formed of a double-curved member (in this example, a single member, but may be a composite member) so as to relax.

  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 by engaging with the bearing portion 20 with a spatial margin, the fin 9 is less likely to come off from the bearing portion 20, The degree of freedom of rotation of the fin 9 is increased.

  On the other hand, when the shaft portion 91 of the fin 9 is locked to the bearing portion 20 in such a manner that the degree of freedom of rotation is increased, an unpleasant interference sound (contact sound) due to the rotation interference between the fin 9 and the rotation restricting piece 20b. ) Is formed, the shaft portion 91 is formed with a curved portion 92 whose thickness is changed and thickened in the 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 fin 9 by abutting against the rotation restricting piece 20b.

  By adopting such a shape of the shaft portion 91, the fin 9 is less likely to be detached from the bearing portion 20, and rotation of the fin 9 is allowed while suppressing rattling and reducing the interference sound. . 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 part that restricts the downward rotation of the fin 9 at a position in contact with the rotation restricting piece 20 a of the bearing portion 20 in the mounting frame 2. In particular, the tip of the protrusion 98 is formed in a shape having an uneven step as shown in the figure, and has a function of relaxing the contact sound and the collision force when coming into contact with the rotation restricting piece 20a. In addition, although the protrusion part 98 of this example is formed so that it may extend and protrude in the left-right direction of the support plate part 93, the form which protrudes partially in the left-right direction of the support plate part 93 may be sufficient.

  A curved interference mitigation portion 95 is formed at the lower end of the shielding plate portion 94 extending downward from the support plate portion 93. Even when there is contact with the screen 4 (or weight bar 5 in the embodiment described later), the interference mitigation unit 95 warps away from the screen 4 (or weight bar 5) so as to relieve the contact sound and collision force. Has a shape.

  Further, 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 located inside the projection piece 96a is formed at the upper front end of the shielding plate portion 94, and the projection piece 96a and the claw portion 99 are configured as a gripping means that functions as a cloth 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.

  FIGS. 3A and 3B are side views for explaining the operation of the fin 9 of one example in the roll screen 1 of the present embodiment. In particular, FIG. Regarding the movement restriction, FIG. 3B illustrates the upper rotation restriction of the fin 9.

  As shown in FIG. 3A, 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 fin 9 is locked by the shaft portion 91 so as to be rotatable by the bending shaft 20f of the bearing portion 20. The protrusion 98 provided on the fin 9 has a function of restricting the downward rotation of the 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 fin 9, the longitudinal direction of the shielding plate portion 94 of the 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 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 fin 9 is substantially perpendicular to the longitudinal direction of the attachment frame 2 (hanging in the vertical direction). Therefore, the design is improved.

  Further, as shown in FIG. 3B, a contact portion 97 is formed in the vicinity of the root of the shaft portion 91 provided on the fin 9. The contact part 97 is a part that restricts the upward rotation of the fin 9 by contacting the rotation restricting piece 20b when the fin 9 is rotated from the basic posture. As a result, the fin 9 is not in contact with the bracket 6 and its mounting surface. Thus, the quality can be maintained without impairing the operability when the fins 9 are attached to the attachment frame 2 of the roll screen 1.

  The fins 9 are provided with protrusions 96a and 96b projecting in a substantially cross-sectional shape at the upper and lower ends of the front surface of the shielding plate portion 94, respectively, and a recess for engaging the upper and lower ends of the fabric 13 is formed. Yes. 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.

  Thus, the fin 9 can be easily attached without causing the fabric 13 to bend by adopting a structure in which only the upper end of the fabric 13 is engaged.

  4 (a), 4 (b), and 4 (c) are side views for individually explaining an operation example of the fin 9 of one example in the roll screen 1 of the present embodiment.

  As shown in FIG. 4A, the fin 9 of the present embodiment has a support plate portion 93 that is bent and protrudes forward from the front side surface of the mounting frame 2 by a length a, and extends downward from the support plate portion 93. Due to the shielding plate portion 94 extending at a length b, it has a substantially L-shaped cross-sectional shape as a whole.

  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 when the operation cord 7 is operated so as to come into contact with the fin 9 according to the present embodiment, the fin 9 rotates so that an operation load is not generated.

  As shown in FIG. 4B, when the 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 fin 9 come into contact with each other. As a basic posture, the light shielding function is maintained while maintaining the state in which the longitudinal direction of the shielding plate portion 94 of the fin 9 is substantially perpendicular to the front-rear direction of the mounting frame 2 (the state in which it is suspended in the vertical direction). it can.

  On the other hand, as shown in FIG. 4C, when the 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 fin 9 come into contact with each other. Even in this case, the fins 9 can be rotated following the thickening of the screen 4, and the light shielding function can be maintained.

  5A, 5B, and 5C show a configuration when the fin 9 is applied to the roll screen 1 of another embodiment.

  In the example shown in FIG. 5A, the screen 4 is suspended from the take-up pipe 3 on the fin 9 side of this embodiment, and the weight bar 5 is located between the fin 9 and the take-up pipe 3. In such a case, the fin 9 of the present embodiment has a curved interference mitigation portion 95 formed at the lower end of the shielding plate portion 94 extending downward from the support plate portion 93, so that interference with the weight bar 5 occurs. There will be no catch.

  Further, as shown in FIG. 5B, even when the upper limit position of the weight bar 5 is set to a position where the weight bar 5 comes into contact with the mounting frame 2, the weight bar 5 extends from the interference mitigation portion 95 to the shielding plate portion 94 in the fin 9. Since the fins 9 move smoothly and rotate, the operability is not impaired. Further, as described with reference to FIG. 3B, a contact portion 97 is formed in the vicinity of the base of the shaft portion 91 provided on the fin 9, and the contact portion 97 is from the basic posture. When the fin 9 is rotated, it is in contact with the rotation restricting piece 20b to restrict the upward rotation of the fin 9. Thereby, the fin 9 becomes non-contact | abutted with respect to the bracket 6 or its attachment surface, and there is no possibility that the fin 9 may be damaged by the collision of the weight bar 5. Therefore, the quality can be maintained without impairing the operability when the fin 9 is attached to the attachment frame 2 of the roll screen 1.

  Further, as shown in FIG. 5C, the basic posture is such that the longitudinal direction of the shielding plate portion 94 of the fin 9 is substantially perpendicular to the front-rear direction of the mounting frame 2 (a state in which the fin 9 is suspended in the vertical direction). If it is desired to always maintain, the position of the movement restricting member 12 attached on the operation cord 7 is adjusted so that the movement restricting member 12 is brought into contact with the operation pulley 8 or the like to stop its rotation, and the weight is stopped. The upper limit position of the bar 5 can be determined. Thereby, the fin 9 becomes non-contact | abutted with respect to the bracket 6 or its attachment surface, and there is no possibility that the fin 9 may be damaged by the collision of the weight bar 5. Further, the basic posture in which the longitudinal direction of the shielding plate portion 94 of the fin 9 is almost perpendicular to the front-rear direction of the mounting frame 2 (a state in which the fin 9 is suspended in the vertical direction) can be maintained. Quality and quality can be maintained.

  Therefore, the fin 9 can be attached to the attachment frame 2 of various roll screens 1 and does not adversely affect its operability, quality, or design.

  Moreover, such a fin 9 can be utilized for the use which improves the light-shielding property and wind shielding property of the downward direction of a frame other than a roll screen. Moreover, the designability of front view can be improved more by attaching the fabric | fabric 13 to the fin 9. FIG.

  However, even if the design of the front view of the roll screen 1 can be improved by the installation of the fins 9, when viewed from the side, the presence of the fins 9 may cause the design of the side view to be impaired. . In addition, when the fabric 13 is attached to the fins 9, the fabric shift may occur due to physical distribution, operation, or due to lapse of time, and the design properties may be impaired. It is necessary to suppress this fabric shift. .

  Therefore, in the roll screen 1 configured as a shielding device according to the present invention, as shown in FIG. 1, the support member 2 a located on the right side of the fin 9 is provided with a side cover 10 a and the support member located on the left side of the fin 9. 2b is provided with a side cover 10b. Although the side cover 10a and the side cover 10b are symmetrical with each other but have the same structure, the side cover 10a and the side cover 10b are collectively referred to as the side cover 10 when it is not necessary to distinguish them.

  Here, the side cover 10 is configured so as to improve rather than impair the function of the fin 9 described above, to suppress light leakage from the side, and to further improve the design when viewed from the side. ing.

  Hereinafter, the side cover 10 of each embodiment will be described in order with reference to the drawings.

(Side cover of Example 1)
FIGS. 6A and 6B are a perspective view partially showing a peripheral configuration of the side cover 10a according to the first embodiment of the present invention and a perspective view showing an assembly position of the side cover 10a.

  First, as shown to Fig.6 (a), the side cover 10 of Example 1 is the substantially flat site | part 110 which covers the side edge part of the fin 9 at the time of a basic posture, and the side surface of the supporting member 2a (or 2b). And a portion 120 that covers the whole (however, a part of the support member 2a (or 2b) may be exposed).

  As shown in FIG. 6B, the side cover 10 of the first embodiment is fixed by engaging only the portion 120 with the side surface of the support member 2a, and the portion 110 is engaged with the fins 9 and the support member 2a. It is not compatible.
