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 the attachment surface by a bracket 6. Each support member 2a, 2b is accommodated by the side cover 10 and improves the design and functionality related to the rotational movement of the fin 9, as will be described later.

An operation pulley (not shown) is provided at the right end of the take-up pipe 3, and an endless operation cord 7 hung around 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 take-up pipe 3 attaches one end of the screen 4 and winds the screen 4 or supports it so as to be rewound. 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.

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 device for preventing the weight of the screen 4 from falling down 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 are formed in 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.

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 member having a double curved surface (a single member or a decoding member) so as to relax.

More specifically, the support plate portion 93 has a shape substantially bent 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.

Further, 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.

Also, a protrusion 98 is formed below the shaft portion 91 provided at the tip of the support plate portion 93, and the protrusion 98 protrudes from the support plate portion 93 along with the shaft portion 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.

In addition, protrusions 96a and 96b projecting in a substantially cross-sectional shape are provided on 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. 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.

FIGS. 4A, 4B, and 4C 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 with a length that prevents light leakage caused by a 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.

5A is an example in which the screen 4 is suspended from the winding pipe 3 on the fin 9 side of the present embodiment, and the weight bar 5 is positioned between the fin 9 and the winding pipe 3. In the example shown in FIG. 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 mounting frame 2 of various roll screens 1 and does not adversely affect its operability, quality, or design.

Also, such fins 9 can be used for purposes other than roll screens to enhance light shielding and wind shielding properties below the frame. 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 present invention, as shown in FIG. 1, a side cover 10 a is provided at the right end portion of the fin 9, and a side cover 10 b is provided at the left end portion of the fin 9. 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 to improve rather than impair the function of the fin 9 described above, and to improve the design when viewed from the side.

Hereinafter, the side covers 10 of Examples 1 and 2 will be described in order with reference to the drawings.

(Side cover of Example 1)
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 has the shape where the site | part 110 which covers the side edge part of the fin 9, and the site | part 120 which generally covers the side surface of the supporting member 2a continue. ing. As will be described later in detail, as shown in FIG. 6B, only the portion 110 covering the side end portion of the fin 9 engages with the side end portion of the fin 9, and the portion 120 is the fin 9 or the support member 2a. Is not engaged.

In particular, the side cover 10 according to the first embodiment includes a portion 110 that covers the side end portion of the fin 9 and a substantially flat plate-like portion 120 that is continuous with the portion 110, and the portion 120 corresponds to the fin 9 in the portion 110. It has an area larger than the area covering the side end. For this reason, as shown in FIG. 6B, the appearance shown in FIG. 6A is more designable than the appearance when the side cover 10 (10a) is not provided. Remarkably improved.

Next, the detailed structure of the side cover 10 according to the first embodiment will be described with reference to FIGS. FIG. 7 is a perspective view showing a detailed structure of the side cover 10 according to the first embodiment of the present invention that can be attached to the fin. FIGS. 8A and 8B are a side view and a plan view, respectively, showing the configuration of the side cover according to the first embodiment of the present invention.

As described above, the side cover 10 according to the first embodiment has a shape in which the portion 110 that covers the side end portion of the fin 9 and the portion 120 that substantially covers the side surface of the support member 2a are continuous. And only the site | part 110 which covers the side edge part of the fin 9 engages with the side edge part of the fin 9, and the site | part 120 does not engage with the fin 9 or the supporting member 2a.

The portion 120 has a flat plate shape as shown in the figure, and has a shape that is continuous with the portion 110 to relieve interference when the side cover 10 is engaged and attached to the rib 120b for reinforcement or the fin 9. For this reason, the shaft portion 91, the curved portion 92, and the built-up portion 120 a that substantially matches the shape of the curved portion 92 in the fin 9 are provided at appropriate positions. In addition, as shown in FIG. 8A (and FIGS. 9A, 9B, and 11B described later), a round-reinforced round is formed at the corner of the rib 120b on the inner surface of the portion 120. A movement restricting portion 121 is formed. As described with reference to FIG. 3A, the fin 9 is provided with a protrusion 98 that restricts the downward rotation of the fin 9 in order to maintain the basic posture. In order to assist the rotation restriction by the restriction part 121, the rotation restriction part 121 is formed. In other words, even when the fin 9 is not provided with the rotation restricting portion 121, the rotation restricting portion 121 in the fin 9 can maintain the basic posture of the fin 9.

On the other hand, the part 110 includes, as main constituent elements, an accommodating portion 111 that engages with a side end portion of the shielding plate portion 94 in the fin 9, an upper detachment preventing piece 113 that protrudes from the accommodating portion 111, and a lower detachment preventing piece 114. And a pair of front and rear shaft pressing pieces 116 continuous above the housing portion 111 and a return portion 118 projecting rearward from the housing portion 111 in parallel with the portion 120, thereby accommodating the side end portion of the fin 9. It is possible. As shown in FIG. 8A (and FIGS. 9A, 9B, and 12 described later), the front shaft pressing piece 116 has a function of restricting the upward rotation of the fin 9. Have. As described with reference to FIG. 3B, the fin 9 is provided with a contact portion 97 for restricting the upward rotation of the fin 9. Dynamic regulation can be assisted. In other words, even when the abutting portion 97 is not provided on the fin 9, the upward rotation of the fin 9 can be restricted by the front shaft pressing piece 116 in the fin 9. .

A dough presser 119 is provided at an appropriate position in the accommodating portion 111, and a plurality of first engaging protrusions 112 are provided (see FIGS. 7 and 8A). The plurality of first engaging protrusions 112 engage with each other so as to press the upper side of the shielding plate part 94 in the fin 9 and the protruding piece 96a from both sides thereof. Thus, when the fabric 13 is attached to the fin 9, the side cover 10 according to the first embodiment is gripped when the upper end of the fabric 13 is gripped by the claw portion 99 located inside the projection piece 96 a of the fin 9. For example, even if the cloth 13 is thin, the cloth 13 can be securely held by the fins 9. The fabric presser 119 has a function of reinforcing the storage portion 111 and a function of pressing the fabric 13 attached to the fins 9, and can suppress the bending of the fabric 13. As described above, when the fabric 13 is attached to the front surface of the fin 9, the side cover 10 according to the first embodiment has the fabric presser 119 and the first engagement with the accommodating portion 111 that accommodates the side end portion of the fin 9. A fabric stopper for the fabric 13 is provided by the projection 112, the side surface shape of the accommodating portion 111, and the like. For this reason, the side cover 10 of Example 1 can improve the function of the fin 9 more.

Further, the upper detachment prevention piece 113 and the lower detachment prevention piece 114 respectively project the support plate portions 93 of the fins 9 on the upper and lower sides thereof and protrude from the accommodation portion 111. The upper detachment prevention piece 113 and the lower detachment prevention piece 114 are provided on the side even if an external force acting in the left-right direction is generated on the portion 120 when the side cover 10 of the first embodiment is engaged with the side end of the fin 9. The cover 10 has a function of making it difficult to easily come off the fin 9 (details will be described later).

In this example, a plurality of second engagement protrusions 115 are provided on the lower surface of the upper detachment prevention piece 113. The plurality of second engagement protrusions 115 assists the function of holding the support plate portion 93 of the fin 9 sandwiched between the upper-side detachment prevention piece 113 and the lower-side detachment prevention piece 114 from both the upper and lower sides. This makes it difficult for the side cover 10 having the portion 110 connected to the relatively large size portion 120 to be easily detached from the fin 9.

The pair of front and rear shaft pressing pieces 116 are connected to the upper side of the accommodating portion 111 and sandwich the portion between the contact portion 97 near the base of the shaft portion 91 and the support plate portion 93 of the fin 9 from both sides thereof. In addition to suppressing backlash when 10 is engaged with the fin 9, the design as an appearance is improved.

The return portion 118 is formed so as to protrude rearward from the accommodating portion 111 in parallel with the portion 120, and as shown in FIGS. 7 and 8B, a holding portion 118a substantially parallel to the portion 120, and a holding portion 118a. And an inclined portion 118b that is inclined with respect to the portion 120.

The function of this return unit 118 will be described with reference to FIG. FIGS. 9A and 9B are side views showing an operation and a method for attaching and detaching the side cover 10 according to the first embodiment of the present invention, respectively. In order to enhance the understanding of the present invention, FIGS. 9A and 9B show the relationship between the support member 2b and the side cover 10b.

First, as described above, the side cover 10 according to the first embodiment has a shape in which the portion 110 that covers the side end portion of the fin 9 and the portion 120 that substantially covers the side surface of the support member 2a are continuous. Only the side end portion of the fin 9 is engaged, and the portion 120 is not engaged with the fin 9 or the support member 2a.

As shown in FIG. 3A, the fin 9 has a basic posture 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 (hanging in the vertical direction). It is regulated to become. On the other hand, as shown in FIG. 3B, the fin 9 can be rotated from the basic posture to a predetermined rotation angle (shown in FIG. 9B as the maximum rotation angle θ). Yes. In particular, as described above, the side cover 10 of the first embodiment includes the rotation restricting portion 121 reinforced by the column at the corner of the rib 120b on the inner surface of the portion 120 and the front shaft presser at the upper portion of the portion 110. Since the piece 116 is formed, the rotation angle of the fin 9 is reliably regulated between the basic posture and the maximum rotation angle θ.

Accordingly, when the fin 9 is rotated from the basic posture shown in FIG. 9A to the maximum rotation angle θ shown in FIG. 9B, the side cover 10 of the first embodiment is integrated with the rotation. And turn. The rotation of the fins 9 is mainly due to the winding or unwinding operation of the screen 4, and the state shown in FIG. 9 (a) under many usage conditions at rest (when the winding operation is stopped). It is in. For this reason, even when the fin 9 is rotated at a predetermined rotation angle from the basic posture, light leakage from between the lower surface of the mounting frame 2 and the winding pipe 3 can be prevented.

As shown in FIG. 9 (a), when the fin 9 is in the basic posture, it is pressed against the support member 2b by the holding portion 118a (see FIGS. 7 and 8 (b)) in the return portion 118. The side cover 10 (10b) of Example 1 is not easily detached from the fins 9 even when an external force is generated.

On the other hand, as shown in FIG. 9B, in this example, when the fin 9 is in the rotating state at the maximum rotation angle θ, the shaft pressing piece 116 supports the side cover 10 (10b) of the first embodiment. Even if an external force is generated in contact with the member 2b, it is not easily detached from the fin 9. However, when the fin 9 is in a state of a predetermined rotation angle near the maximum rotation angle θ (a rotation angle slightly smaller than the maximum rotation angle θ), the support member 2b is pressed down by the holding portion 118a in the return portion 118. Is released, and the side cover 10 (10b) of the first embodiment can be intentionally removed from the fin 9 by the inclined portion 118b (see FIGS. 7 and 8B) in the return portion 118. Therefore, the side cover 10 (10a, 10b) according to the first embodiment is engaged with the support members 2a, 2b connected to the mounting frame 2 so as to prevent the fin 9 from coming off depending on the rotation state of the fin 9. And a disengagement-preventing return portion 118 that can be switched between an engaging mode for releasing and a non-engaging mode for releasing the engagement.

Further, even when the fin 9 is rotated in operation to reach the maximum rotation angle θ, the fins 9 are not easily detached because of the above-described upper detachment prevention piece 113 and lower detachment prevention piece 114. Even if the fin 9 is returned to the basic posture by stopping the operation even when the maximum rotation angle θ is off, the inclined portion 118b of the return portion 118 is connected to the holding portion 118a. It returns to the stable engagement state.

In addition, the side cover 10 (10b) of Example 1 should just cover the side edge part of the fin 9, and when the fin 9 exists in a basic attitude, as shown to Fig.10 (a), it is the support member 2b. As shown in FIG. 10B, even when a part of the lower portion of the support member 2b is exposed as shown in FIG. 10B, the improvement of the design and the function of the fin 9 are maintained. Be drunk.

FIG. 11A shows a schematic perspective view of the side cover 10 (10a) viewed from the inside of the fin 9 when the fin 9 is in the basic posture, and FIG. A schematic perspective view of the side cover 10 (10a) viewed from the inside of the fin 9 when it is in a state of a predetermined rotation angle (a rotation angle slightly smaller than the maximum rotation angle θ) in the vicinity of the maximum rotation angle θ. The figure is shown. If the fins 9 are in the basic posture as shown in FIG. 11A, the side cover 10 is unlikely to come off from the fins 9, and the fins 9 are close to the maximum rotation angle θ as shown in FIG. It is well understood that the side cover 10 can be intentionally removed from the fin 9 if it is in a state of a rotational angle (a rotational angle slightly smaller than the maximum rotational angle θ).

In the state where the side cover 10 is engaged with the fin 9, the shaft pressing piece 116 is positioned away from the portion 120 (at the support member 2a (2b)) as shown in FIGS. Avoiding interference with the support member 2a (2b) at all times in any state where the fin 9 is rotated from the basic posture to the maximum rotation angle θ. A portion 117 is provided (see FIG. 12). In particular, as shown in FIG. 12, in the side cover 10 of the first embodiment, as described above, the front shaft pressing piece 116 is formed in the upper part of the portion 110, and therefore, the front shaft pressing piece 116 is Since it can come into contact with the rotation restricting piece 20b in the mounting frame 2, the maximum rotation angle θ of the fin 9 is reliably restricted.

That is, the side cover 10 is configured to always avoid the rotation interference with the support member 2a (2b) in any state where the fin 9 rotates from the basic posture to the maximum rotation angle θ. As described above, the side cover 10 is not easily detached from the fins 9 except for intentional removal as described above.

And since the side cover 10 of Example 1 is provided with the upper side prevention piece 113 and the lower side prevention piece 114, as shown in FIG. 13, operation without interference with the site | part 120 in the side cover 10 is shown. Not only in the case of the operation of the cord 7 (direction A in the figure), but also in the case of the operation of the operation cord 7 having an interference with the part 120 in the side cover 10 (direction B in the figure), the side cover 10 is operated in the fin 9 It is hard to come off. That is, the disengagement prevention means (the upper disengagement prevention piece 113 and the lower disengagement prevention piece 114) in the side cover 10 provide a contact portion (lower end portion 120d) with the operation cord 7 when the operation cord 7 is operated in the upward and pulling directions. Have.

That is, the side cover 10 according to the first embodiment is shown in the portion 120 (particularly, shown in FIGS. 12 and 13) in the side cover 10 when the operation cord 7 such as a ball chain is operated obliquely (direction B in FIG. 13). May interfere with the lower end 120d) of the part 120. Even in such a case, the side cover 10 according to the first embodiment is provided with the upper-side detachment prevention piece 113 and the lower-side detachment prevention piece 114, so that the side cover 10 is not easily detached from the fins 9. . In other words, when the operation cord 7 is constituted by a ball chain, the operation cord 7 comes into contact with the lower end portion 120d of the portion 120 and makes a sound when the operation is performed obliquely (in the B direction in FIG. 12). When this sound is generated, a warning sound indicating that the operation is performed obliquely is generated, and an effect of preventing damage to the side cover 10 and the ball chain is produced. That is, the part 120 has a contact part (lower end part 120d) with the operation cord 7 when the operation code 7 is obliquely operated outward.

Accordingly, the side cover 10 according to the first embodiment includes the disengagement prevention means (upper disengagement prevention piece 113 and lower disengagement prevention piece 114) that presses and engages a part of the side end portion of the fin 9, and thus is particularly a part. It becomes tolerant to an external force acting on 120 (particularly an external force in an oblique direction).

Furthermore, as shown in FIG. 9A, the side cover 10 according to the first embodiment has a configuration in which a fabric presser 119 and a plurality of first engaging protrusions 112 are provided at appropriate positions in the housing portion 111. When attaching the fabric 13 to the fin 9, even if the fabric 13 is thin, the fabric 13 can be securely held by the fin 9 and the bending of the fabric 13 can be suppressed. Can be improved.

Further, as shown in FIG. 14A, the side cover 10 according to the first embodiment is provided with a concave portion 110a between the upper holding portion 110b and the lower holding portion 110c as the shape of the portion 110 when viewed from the front. ing. The upper holding portion 110b increases the gripping force of the protruding piece 96a of the fin 9 that engages with the upper end of the fabric 13, and the lower holding portion 110c suppresses fluttering by the protruding piece 96b of the fin 9 that engages with the lower end of the fabric 13. It has the necessary width to increase power. On the other hand, even when the side cover 10 is provided, the recess 110a is formed so as to expose the fabric 13 as much as possible (the broken line in the figure is the region of the fabric 13) and improve the design.

That is, when only considering the viewpoint of strengthening the holding force of the fabric 13 by the fins 9, the side cover 10 has an upper holding portion 110b as shown in FIG. It is also possible to adopt a configuration in which the lower holding portion 110c and the lower holding portion 110c are linearly connected, and the concave portion 110a is not provided. However, by providing the concave portion 110a as the shape of the portion 110 in a front view, the fabric 13 by the fins 9 can be seen as compared with FIG. 14 (a) and FIG. 14 (b) or as understood with reference to FIG. Not only can the holding power be strengthened, but the design can be further improved.

Further, as a modification of the side cover 10 of the first embodiment, for example, when the rotation of the fin 9 is locked to cover the side end portion, or the side end of a fin (not shown) configured to be unrotatable. When it is desired to cover the portion, as shown in FIG. 15, a holding wall 120 c for holding at least a part of the side end portion of the support member 2 a (2 b) may be further provided in the portion 120.

Therefore, the side cover 10 according to the first embodiment can improve the design of the fins 9 and suppress the cloth displacement when the predetermined cloth 13 is attached to the fins 9. In particular, the side cover 10 according to the first embodiment has a configuration in which the fin 9 and the support member 2a (2b) are continuously connected to each other, so that there is no gap and the design is high.

Further, the side cover 10 of the first embodiment is detachable from the fins 9 and is not easily detached from the fins 9 and maintains operability while not hindering operability. That is, the side cover 10 according to the first embodiment is not removable from the fin 9 in the basic posture, and is a predetermined rotation angle near the maximum rotation angle θ (a rotation slightly smaller than the maximum rotation angle θ). Since the fins 9 at an angle) are removable, compatibility between quality reliability and maintainability after the roll screen 1 is installed is realized.

(Further modifications)
From the viewpoint of mainly improving the design by covering the side end portion of the fin 9 in the basic posture with the portion 110 and covering one side surface of the support member 2a (2b) with the portion 120. 16 and FIG. 17 can be adopted.

16A and 16B are a perspective view partially showing a peripheral configuration of a side cover 10 of a further modification according to the present invention, and a perspective view showing an assembly position of the side cover 10 of the modification, respectively. is there. Further, as a further modification, FIGS. 17A and 17B are a perspective view partially showing a peripheral configuration of a side cover 10 of a further modification according to the present invention, and a side cover 10 of the modification. It is a perspective view which shows the assembly position of. Similar components are denoted by the same reference numerals.

First, the modified side cover 10 shown in FIG. 16 will be described. The side cover 10 of the modification shown in FIG. 16 has a substantially flat portion 110 covering the side end of the fin 9 in the basic posture, and the entire side surface of the support member 2a (however, a part of the support member 2a is exposed). It may have a shape that is continuous with a portion 120 that covers the same. And as shown in FIG.16 (b), only the site | part 120 engages with the side edge part of the supporting member 2a, and the site | part 110 does not engage with the fin 9 or the supporting member 2a.

For this reason, the external appearance shown in FIG. 16 (a) is more in design as compared with the external appearance when the side cover 10 (10a) is not provided, as understood in FIG. 16 (b). Remarkably improved.

Further, the side cover 10 of the modification shown in FIG. 16 can be further modified to configure the side cover 10 as shown in FIG. Also in the side cover 10 of the modified example shown in FIG. 17, the substantially flat portion 110 covering the side end portion of the fin 9 in the basic posture and the entire side surface of the support member 2a (however, a part of the support member 2a is exposed). It may have a shape that is continuous with the portion 120 that covers the same. And as shown in FIG.17 (b), only the site | part 120 engages with the side edge part of the supporting member 2a, and the site | part 110 does not engage with the fin 9 or the supporting member 2a.

For this reason, the external appearance shown in FIG. 17 (a) is more in design as compared with the external appearance when the side cover 10 (10a) is not provided, as understood in FIG. 17 (b). Remarkably improved.

However, in the example shown in FIG. 17, even when the fin 9 is rotated from the basic posture by a predetermined rotation angle θa, the portion 110 can cover the side end portion of the fin 9. The rotation angle θa may be the same as the maximum rotation angle θ, but may be a practical rotation angle of the fin 9 (0 <θa ≦ θ).

That is, in the example shown in FIG. 17, even when the fin 9 is rotated from the basic posture at a predetermined rotation angle θa, light leakage from the lower surface of the mounting frame 2 and the winding pipe 3 is prevented. Can do.

(Side cover of Example 2)
Next, the side cover 10 of Example 2 will be described with reference to FIGS. In addition, the same reference number is attached | subjected to the component which functions similarly to Example 1. FIG.

FIG. 18 is a perspective view partially showing the peripheral configuration of the side cover 10 according to the second embodiment of the present invention and showing the assembly position of the side cover 10. Moreover, Fig.19 (a) is a perspective view which shows the detailed structure of the side cover 10 of Example 2 by this invention. Note that FIG. 19B is a perspective view showing a modification thereof, and details will be described later.

In the above-described side cover 10 of the first embodiment, the example in which the portion 110 that covers the side end portion of the fin 9 and the portion 120 that substantially covers the side surface of the support member 2a are continuous has been described. The second side cover 10 has a portion 110 that covers the side end portion of the fin 9, although the shape is different, and a portion 130 that is continuous with the portion 110. The side cover 10 of the second embodiment is particularly different in that a portion 130 is provided instead of the portion 120 of the first embodiment. The part 130 has a shape that is close to or in close contact with the cover 100 that covers the side surface of the support member 2a in the basic posture (see FIG. 21A).

Further, as can be understood from FIG. 18, the appearance shown in FIG. 21A is remarkably improved in design as compared with the appearance when the side cover 10 (10a) is not provided.

Also in the side cover 10 of the second embodiment, only the portion 110 covering the side end portion of the fin 9 is engaged with the side end portion of the fin 9, and the portion 130 is engaged with the fin 9, the support member 2 a, or the cover 100. It is not to be.

First, the detailed structure of the side cover 10 according to the second embodiment will be described with reference to FIGS. 18 and 19A.

The part 130 in the side cover 10 of the second embodiment has a flat shape as shown in FIG. 19A and is continuous with the part 110, and ribs 130b are provided at the edges for reinforcement. ing.

On the other hand, the part 110 includes, as main constituent elements, an accommodating portion 111 that engages with a side end portion of the shielding plate portion 94 in the fin 9, an upper detachment prevention wall 113 a formed continuously with the accommodating portion 111, and a lower detachment. A prevention wall 114a, a shaft pressing piece 116 formed only in front of the housing portion 111, and a return portion 118 projecting rearward from the housing portion 111 in parallel with the portion 130. 9 side end portions can be accommodated.

In the side cover 10 according to the second embodiment, the shaft pressing piece 116 and the return portion 118 are connected to each other with a vertical wall. Therefore, as shown in FIG. 18, the interference with the support member 2a (2b) or the cover 100 is achieved. The interference avoiding portion 117 to be avoided is formed.

Also in the side cover 10 of the second embodiment, as in the first embodiment, as shown in FIG. 19A, a cloth presser 119 is provided at an appropriate position in the housing portion 111, and a plurality of first engaging protrusions are provided. A portion 112 is provided. The plurality of first engaging protrusions 112 engage with each other so as to press the upper side of the shielding plate part 94 in the fin 9 and the protruding piece 96a from both sides thereof. Thus, when the fabric 13 is attached to the fin 9, the side cover 10 according to the second embodiment is gripped when the upper end of the fabric 13 is gripped by the claw portion 99 located inside the protruding piece 96 a of the fin 9. For example, even if the cloth 13 is thin, the cloth 13 can be securely held by the fins 9. The fabric presser 119 has a function of reinforcing the storage portion 111 and a function of pressing the fabric 13 attached to the fins 9, and can suppress the bending of the fabric 13. As described above, also in the side cover 10 according to the second embodiment, when the fabric 13 is attached to the front surface of the fin 9, the fabric retainer 119 and the first engagement member are accommodated in the accommodating portion 111 that accommodates the side end portion of the fin 9. A dough stop for the dough 13 is provided by the side shape of the mating protrusion 112 and the accommodating portion 111 or the like. For this reason, the side cover 10 of Example 1 can improve the function of the fin 9 more.

Further, although the upper side prevention wall 113a and the lower side prevention wall 114a are not configured to provide the portion 120 as in the first embodiment, the shape of the side cover 10 of the second embodiment is different from that of the fin 9 although the shape is different. The side cover 10 has a function of preventing the side cover 10 from being easily detached from the fins 9 when engaged.

In this example, a plurality of second engagement protrusions 115 are provided on the lower surface of the upper detachment prevention wall 113a. The plurality of second engaging protrusions 115 assists the function of holding the support plate portion 93 of the fin 9 sandwiched between the upper detachment prevention wall 113a and the lower detachment prevention wall 114a from both the upper and lower sides.

As shown in FIG. 19A, the side cover 10 according to the second embodiment includes a plurality of first engagement protrusions 112 and a plurality of second engagement protrusions 115 that function in the same manner as in the first embodiment. In this example, a suitable example that works satisfactorily as a function of preventing detachment from the fin 9 is shown. However, the first and second protrusions 112 and 115 can be appropriately changed according to the shape of the fin 9. For example, as in the modification shown in FIG. 19B, a plurality of first engagement protrusions 112 are arranged at appropriate positions at positions different from those of the second embodiment shown in FIG. The portion 115 may be configured not to be provided, and at least the side cover 10 only needs to be engaged and held with the fin 9. This also applies to the side cover 10 of the first embodiment.

Moreover, in the side cover 10 of Example 2, since it is set as the detailed site | part 130 compared with the site | part 120 of Example 1, it is comprised as one shaft pressing piece 116 ahead, but is the same as that of Example 1. Alternatively, a pair of front and rear shaft pressing pieces 116 may be configured. The shaft pressing piece 116 suppresses rattling when the side cover 10 is engaged with the fins 9 and improves the design as an appearance.

The return portion 118 in the side cover 10 of the second embodiment functions in the same manner as that of the first embodiment although the shape is different from that of the return portion 118 of the first embodiment.

The function of the return unit 118 in the second embodiment will be described with reference to FIG. FIGS. 20A and 20B are side views showing an operation and a method of attaching / detaching the side cover 10 according to the second embodiment of the present invention, respectively. In order to enhance the understanding of the present invention, FIGS. 20A and 20B show the relationship between the support member 2b and the side cover 10b.

First, as described above, the side cover 10 according to the second embodiment includes the portion 110 that covers the side end portion of the fin 9 and the portion 130 that is close to or in close contact with the cover 100 that covers the side surface of the support member 2a in the basic posture. , Only the portion 110 is engaged with the side end portion of the fin 9, and the portion 130 is not engaged with the fin 9, the support member 2 a, or the cover 100.

As shown in FIG. 3A, the fin 9 has a basic posture 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 (hanging in the vertical direction). It is regulated to become. On the other hand, as shown in FIG. 3B, the fin 9 can be rotated from the basic posture to a predetermined rotation angle (shown in FIG. 20B as the maximum rotation angle θ). Yes.

Therefore, when the fin 9 is rotated from the basic posture shown in FIG. 20A to the maximum rotation angle θ shown in FIG. 20B, the side cover 10 of the second embodiment is integrated with the rotation. And turn. The rotation of the fins 9 is mainly due to the winding or unwinding operation of the screen 4, and the state shown in FIG. 20 (a) under many usage conditions when stationary (when the winding operation is stopped). It is in.

As shown in FIG. 20A, when the fin 9 is in the basic posture, the side cover 10 (10b) of the first embodiment does not generate any external force because it is pressed against the support member 2b by the return portion 118. The fin 9 is not easily detached.

On the other hand, as shown in FIG. 20B, also in this example, when the fin 9 is in the rotating state at the maximum rotation angle θ, the side cover 10 (10b) of Example 2 is used as in Example 1. The shaft pressing piece 116 comes into contact with the support member 2b and does not easily come off the fin 9 even if an external force is generated. Similarly to the first embodiment, when the fin 9 is in a state of a predetermined rotation angle near the maximum rotation angle θ (a rotation angle slightly smaller than the maximum rotation angle θ), the support member by the return portion 118 is supported. The side cover 10 (10b) of the second embodiment can be configured to be intentionally removed from the fin 9 by releasing the pressing of 2b. Therefore, also in the side cover 10 (10a, 10b) of the second embodiment, the support members 2a, 2b connected to the mounting frame 2 are prevented from coming off from the fin 9 depending on the rotation state of the fin 9. It is possible to provide a return preventing portion 118 for preventing disengagement that can be switched between an engaging mode to be engaged and a non-engaging mode to release the engagement.

Further, even when the fin 9 is rotated in operation to reach the maximum rotation angle θ, the fins 9 cannot be easily detached because of the upper detachment prevention wall 113a and the lower detachment prevention wall 114a. Even if the fin 9 is returned to the basic posture by stopping the operation even if the maximum rotation angle θ is disengaged, the return portion 118 automatically returns to a stable engagement state. . Accordingly, the side cover 10 according to the second embodiment includes the disengagement prevention means (upper disengagement prevention wall 113a and lower disengagement prevention wall 114a) that presses and engages a part of the side end portion of the fin 9, and therefore, particularly the site. It becomes tolerant to external force acting on 130 (particularly, external force in an oblique direction).

However, in the case of the side cover 10 of the second embodiment, since the possibility that the operation cord 7 interferes with the part 130 during operation is small, the side cover 10 is less likely to come off the fin 9 than the configuration of the first embodiment.

In the state where the side cover 10 of the second embodiment is engaged with the fin 9, the shaft pressing piece 116 is an arbitrary rotation of the fin 9 from the basic posture to the maximum rotation angle θ as shown in FIG. In this state, there is always provided an interference avoiding portion 117 that avoids rotational interference with the support member 2a (2b) and the cover 100 (see FIG. 21B).

That is, also in the side cover 10 of the second embodiment, the rotation interference with the support member 2a (2b) and the cover 100 is always avoided in any state where the fin 9 rotates from the basic posture to the maximum rotation angle θ. Therefore, the side cover 10 is not easily detached from the fins 9 in operation other than intentionally removing as described above.

Further, the side cover 10 of the second embodiment is provided with the upper side prevention wall 113a and the lower side prevention wall 114a, so that the side cover 10 is further unlikely to be detached from the fins 9 in operation.

Further, as shown in FIG. 19A, the side cover 10 according to the second embodiment has a configuration in which a fabric presser 119 and a plurality of first engagement protrusions 112 are provided at appropriate positions in the housing portion 111. When attaching the fabric 13 to the fin 9, even if the fabric 13 is thin, the fabric 13 can be securely held by the fin 9 and the bending of the fabric 13 can be suppressed. Can be improved.

Therefore, also in the side cover 10 according to the second embodiment, the design of the fins 9 can be improved, and the cloth displacement can be suppressed when the predetermined cloth 13 is attached to the fins 9. In particular, since the side cover 10 of Example 2 is separated from the cover 100 for the support member 2a (2b), the design can be made substantially the same regardless of the size of the support member 2a (2b). it can.

Also, the side cover 10 of the second embodiment is also detachable from the fins 9 and is not easily detached from the fins 9, so that maintainability is maintained and operability is not hindered. That is, also in the side cover 10 of the second embodiment, the fin 9 in the basic posture is not removable, and a predetermined rotation angle near the maximum rotation angle θ (a rotation slightly smaller than the maximum rotation angle θ). Since the fin 9 at the moving angle) can be removed, both the reliability in quality and the maintainability after the roll screen 1 is installed are realized.

Also, the side cover 10 of the second embodiment can be configured such that the concave portion 110a is provided in the side cover 10 of the first embodiment as shown in FIG. Thereby, also in the side cover 10 of Example 2, not only the holding | maintenance force of the fabric | fabric 13 by the fin 9 can be strengthened but the designability can be improved further.

As described above, the present invention has been described by giving examples of 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 idea thereof. In particular, the shape / structure of the shaft portion 91 of the fin 9 and the method of locking are only described as an example. For example, the shaft portion 91 of the fin 9 may be formed by a round shaft or the like. If the shaft portion 91 is, for example, a roll screen, the shaft portion 91 may be supported by the support members 2a and 2b instead of being supported by the mounting frame 2 as a frame.

In addition, the fin 9 may be fixed so as not to be rotated in addition to the configuration in which the fin 9 is rotatable with respect to the frame. Further, the fin 9 is not limited to a form that rotates with respect to the frame body, but may be an arbitrary movable form such as a form that slides with respect to the frame body.

Moreover, it can comprise so that the side cover 10 which concerns on this invention may be attached to the side edge part of the fin 9 provided in shielding apparatuses, such as not only a roll screen but a horizontal blind, a raising curtain, a pleat screen. .
