Description

The present invention relates to a roller screen and a method for manufacturing a roller screen.

A conventional roller screen is shown in Japanese Utility Model Publication No. 63-24785 (Patent Document 1). The roller screen disclosed in this document has a partition plate that divides the inside of a cylindrical weight bar into two chambers in the vertical direction, and a protruding piece is provided in the upper chamber. A plate-shaped connecting support member (locking plate) is attached to the tip of the screen to connect the screen to the weight bar. The screen can be connected to the weight bar by inserting the tip of the screen with the connecting support member attached between the partition plate and the protruding piece.

Japanese Utility Model Publication No. 63-24785

However, in conventional roll screens such as those disclosed in Patent Document 1, the leading edge of the screen is attached to the connecting support member via double-sided tape. Therefore, when the temperature in the vicinity of the window surface to which the roll screen is attached becomes high due to solar heat, the connecting support member expands and contracts due to the heat, which causes wrinkles in the screen. In addition, the degree of tension applied to the screen when attaching the connecting support member is also one of the factors that cause wrinkles. Furthermore, when the connecting support member is fixed to the screen using staples or the like to reliably prevent the connecting support member from coming off, if a material that contracts due to heat is used as the connecting support member, the fixed parts fixed by the staples will be pulled together, and if a material that expands due to heat is used as the connecting support member, the fixed parts fixed by the staples will be pushed together, which causes a problem of wrinkles being more noticeable due to the strong load being applied to some parts.

The present invention was made in consideration of these problems, and its purpose is to provide a roll screen and a method for manufacturing a roll screen that can prevent wrinkles from occurring in the screen even if the connecting support members attached to the screen expand and contract due to heat, without affecting the screen.

In order to solve the above problem, according to a first aspect of the present invention, a roll screen is provided, comprising a screen that shields an opening, a connecting support member attached to an end of the screen, and a connected member to which at least one of the upper end and the lower end of the screen is connected via the connecting support member, and the connecting support member is arranged in multiple rows in the width direction of the screen.

With this configuration, the connecting support members are attached in a separated state in the width direction of the screen, making it easier to release screen distortion caused by expansion and contraction of the connecting support members and screen distortion caused by dependency on the attachment of the connecting support members. Therefore, even if the connecting support members attached to the screen expand and contract due to heat, the expansion and contraction of the connecting support members does not affect the screen, and it is possible to prevent wrinkles from occurring in the screen.

The present invention can be applied in various ways. For example, each of the multiple connecting support members may be fixed to the edge of the screen via a single fixing means. With this configuration, the connecting support members are separated between the fixing means, so that it becomes easier to release distortion of the screen caused by the attachment of the fixing means, i.e., by the application of load to the attachment portion, and the effect of preventing the occurrence of wrinkles can be improved.

The multiple connecting support members may also be arranged so that a predetermined gap is provided between adjacent connecting support members. With this configuration, the distortion of the screen can be evenly released, improving the effect of preventing wrinkles from occurring. Even if the connecting support members are made of a material that expands when heated, it is possible to prevent adjacent connecting support members from interfering with each other.

The gap may also be a slit shape formed by cutting the connecting support member in the vertical direction of the screen. This configuration is advantageous in that the connecting support member can be easily processed.

The screen may also be separated between adjacent connecting support members. With this configuration, the impact of the expansion and contraction of the connecting support members on the screen is further reduced.

The connecting support members may have adjacent sides, either in the thickness direction or at least one of the lower ends, curved. With this configuration, when connecting the connecting support members to the connected members, the corners of the connecting support members do not get caught on the connected members, improving workability.

According to a second aspect of the present invention, there is provided a method for manufacturing a roll screen comprising a screen for shielding an opening, a connected member connected to at least one of the upper and lower ends of the screen, and a connecting support member for connecting the screen to the connected member, characterized in that one of the connecting support members is attached to the end via a plurality of fixing means, and the connecting support member is cut and processed together with the screen between the plurality of fixing means.

With this configuration, the connecting support members can be attached to the screen and then processed together with the screen, thereby improving productivity during the manufacture of the roller blind according to the first aspect of the present invention.

According to the present invention, it is possible to provide a roll screen and a method for manufacturing a roll screen that can prevent the screen from becoming wrinkled even if the connecting support members attached to the screen expand and contract due to heat, without the expansion and contraction of the connecting support members affecting the screen. Other effects of the present invention will be described in the description of the embodiment of the invention below.

A preferred embodiment of the present invention will be described in detail below with reference to the attached drawings. Note that in this specification and drawings, components having substantially the same functional configuration are designated by the same reference numerals to avoid redundant description.

(First embodiment)
The overall configuration of the roll screen 100 according to this embodiment will be described with reference to Figs. 1 and 2. Fig. 1 is a front view showing the overall configuration of the roll screen 100 according to this embodiment. Fig. 2 is a front view showing the mounting state of the screen stopper plate 120. As shown in Fig. 1, the roll screen 100 includes a screen 110 that shields the opening, a screen stopper plate (connecting support member) 120 attached to the end of the screen 110, a winding pipe (connected member) 130 connected to the upper end of the screen 110 via a fixed plate (not shown), and a bottom rail (connected member) 140 connected to the lower end of the screen 110 via the screen stopper plate 120. The screen stopper plate 120 is configured by arranging a plurality of screen stopper plates 120 in parallel in the width direction of the screen 110. In addition, when connecting the upper end of the screen 110 to the winding pipe 130, the screen stopper plate 120 may be used instead of the fixed plate (not shown) described above. Specifically, a screen stopper plate 120 attached to the upper end of the screen 110 may be engaged with a groove (not shown) of the winding pipe 130, thereby connecting the upper end of the screen 110 to the winding pipe 130. Each component of the roller blind 100 will be described below.

(Screen 110)
The screen 110 shields the opening. As shown in Fig. 1, the upper end of the screen 110 is connected to the winding pipe 130 so as to be able to be wound and unwound. The screen 110 rises when wound around the winding pipe 130, and falls when unwound from the winding pipe 130. Both ends of the screen 110 are inserted into guide rails 150 provided on the left and right fixing surfaces FS of the window frame WF, respectively, and the screen 110 is guided as it rises and falls by the guide rails 150.

(Screen stopper plate 120)
The screen stopper plate 120 connects the screen 110 to the winding pipe 130 or the bottom rail 140. Hereinafter, the screen stopper plate 120, which is a characteristic feature of this embodiment, will be described with reference to FIG.

As shown in FIG. 2, the screen stop plate 120 is attached to the end of the back surface 110b of the screen 110, and is configured by arranging a plurality of screen stop plates 120 side by side in the width direction of the screen 110. The screen stop plate 120 is a thin rectangular flat plate. The screen stop plate 120 may be formed with a curved surface in the thickness direction of the side and the lower end. With this configuration, when the screen stop plate 120 is connected to the winding pipe 130 or the bottom rail 140, the corners of the screen stop plate 120 do not get caught on the bottom rail 140, making the work easier.

(Winding pipe 130)
The winding pipe 130 supports the screen 110 so that it can be wound up and unwound. As shown in Fig. 1, the upper end of the screen 110 is connected to the winding pipe 130. The winding pipe 130 is rotatably supported by side plates 164 provided at both ends of an elongated set frame 160 which is fixed to the window frame WF via a bracket 162.

One end of the winding pipe 130 is supported by one side plate 164 via a pulley 132, and the other end is rotatably supported by the other side plate 164. The winding pipe 130 and pulley 132 rotate together. An operating chain 134 formed into a loop by a connector 136 is wound around the pulley 132. By pulling down the front or rear side of the operating chain 134, the rotation of the pulley 132 is controlled, and the rotation of the winding pipe 130 is controlled.

(Bottom rail 140)
The bottom rail 140 holds the screen 110 in a tensed state by its weight. The bottom rail 140 is attached to the lower end of the screen 110 as shown in Fig. 1. Bottom rail caps 142 are provided on both ends of the bottom rail 140. The bottom rail caps 142 are inserted into the guide rails 150.

At the lower end of the bottom rail 140, a bottom rail cushioning material 144 that fills the gap between the bottom rail 140 and the bottom of the window frame WF is provided over the entire length of the bottom rail 140. The bottom rail cushioning material 144 is made of an elastically deformable material, and deforms to fit closely to the bottom of the window frame WF when the bottom rail 140 is in the lowest position.

The configuration of each part of the roller blind 100 has been described above. The state in which the screen stopper plate 120 is attached to the screen 110 will now be described with reference to FIG. 3. FIG. 3 is a cross-sectional view showing the attached state of the screen stopper plate 120, where (a) is a cross-sectional view taken along line A-A in FIG. 2, and (b) is a cross-sectional view taken along line B-B in FIG. 2.

As shown in FIG. 3, the screen stopper plates 120 are attached to the screen 110 with double-sided tape 170, and are fixed to the back surface 110b of the screen 110 via one staple (fixing means) 122. The staple 122 is driven into the screen stopper plate 120 at approximately the center in the height direction. The staple 122 is driven in from the front surface 110a to the back surface 110b of the screen 110, as shown by arrow a in FIG. 3(a).

The above describes the mounting state of the screen stopper plate 120 on the screen 110. Next, the mounting and processing procedure of the screen stopper plate 120 on the screen 110 will be described with reference to FIG. 4. FIG. 4 is a front view showing the mounting and processing procedure of the screen stopper plate 120, where (a) is a diagram showing step 1, (b) is a diagram showing step 2, (c) is a diagram showing step 3, and (d) is a diagram showing step 4.

Step 1: As shown in FIG. 4A, the rear surface 110b of the screen 110 is placed facing up.
4B, a long screen fixing plate 120 extending across the entire width of the screen 110 is placed on the lower end of the back surface 110b of the screen 110. At this time, the back surface 110b of the screen 110 and the screen fixing plate 120 are temporarily fixed with double-sided tape 170.
Step 3: As shown in FIG. 4( c ), the screen fixing plate 120 is fixed to the screen 110 at multiple points with staples 122 .
Step 4: As shown in FIG. 4( d ), the screen fixing plate 120 is divided together with the screen 110 in the vertical direction of the screen 110 at a position between adjacent staples 122 to form slits 112 , 124 .

In this way, multiple screen stop plates 120 can be arranged side by side in the width direction at the end of the screen 110.

The above describes the attachment and processing procedures for the screen stopper plate 120 to the screen 110. Next, the state in which the screen 110 is attached to the bottom rail 140 will be described with reference to Figures 5 and 6. Figure 5 is a cross-sectional view of a portion corresponding to the B-B cross section in Figure 2, and shows the state in which the screen stopper plate 120 is attached to the bottom rail 140. Figure 6 is a diagram showing the state of the screen 110 near the bottom rail 140.

As shown in FIG. 5, the screen 110 is accommodated in the bottom rail 140 from the side with the screen stop plates 120 folded 180 degrees toward the back surface 110b. By folding the screen stop plates 120 180 degrees toward the back surface 110b, the screen 110 hides the screen stop plates 120 and they cannot be seen from the front surface 110a. As shown in FIG. 6, the screen 110 is attached so that all the screen stop plates 120 are accommodated in the bottom rail 140.

As shown in FIG. 5, the upper part of the screen stop plate 120 protrudes upward from the front side of the bottom rail 140, but is hidden by the surface 110a of the screen 110. Also, as shown in FIG. 6, the screen stop plate 120 is attached in a state where it is separated for each staple 122 in the width direction of the screen 110. This makes it easier to release distortion of the screen 110 caused by the expansion and contraction of the screen stop plate 120 and distortion of the screen 110 caused by dependency on the installation of the staple 122, and prevents wrinkles from occurring in the screen 110.

Here, a conventional roll screen 500 will be described with reference to Figs. 7 and 8. Fig. 7 is a diagram showing the state in which a conventional screen stopper plate 520 is attached. Fig. 8 is a diagram showing the state of the screen 510 near the bottom rail 540 when a conventional screen stopper plate 520 is used.

As shown in FIG. 7, a long screen stopper plate 520 that extends across the entire width of the screen 510 is attached to the lower end of the back surface 510b of the screen 510 by a staple 522. As shown in FIG. 8, the screen 510 is attached to the bottom rail 540 by the screen stopper plate 520. Since the screen stopper plate 520 is connected to the screen 510 at multiple points, when the vicinity of the window to which the roller blind 500 is attached becomes hot due to solar radiation heat, the screen stopper plate 520 expands and contracts due to the heat, and wrinkles 510c occur in the screen 510 due to the expansion and contraction.

(Effects of the First Embodiment)
As described above, according to this embodiment, the screen stop plates 120 are attached in a state separated in the width direction of the screen 110, which makes it easier to release distortion of the screen 110 caused by expansion and contraction of the screen stop plates 120 and distortion of the screen 110 caused by dependency on the attachment of the staples 122. Therefore, even if the screen stop plate 120 attached to the screen 110 expands and contracts due to heat, the expansion and contraction of the screen stop plate 120 does not affect the screen 110, and it is possible to prevent wrinkles from occurring in the screen 110.

In addition, because the screen stopper plate 120 is separated between each staple 122, it is easier to release the distortion of the screen 110 caused by the staples 122, improving the effect of preventing wrinkles from occurring.

In addition, even if the screen stop plates 120 are made of a material that expands when heated, it is possible to prevent adjacent screen stop plates 120 from interfering with each other.

In addition, the gap is a slit shape formed by cutting the screen stopper plate 120 in the vertical direction of the screen 110, which is advantageous in that the screen stopper plate 120 can be easily processed.

In addition, because the screen 110 is separated between adjacent screen stop plates 120, the impact on the screen 110 caused by the expansion and contraction of the screen stop plates 120 is further reduced.

In addition, since the screen 110 can be processed after the screen stopper plate 120 is attached to the screen 110, productivity during manufacturing can be improved.

Second Embodiment
The configuration of a roller screen 200 according to the second embodiment will be described with reference to Fig. 9. Fig. 9 is a diagram showing the state of a screen stopper plate 220 of the second embodiment. The roller screen 200 of this embodiment differs from the roller screen 100 of the first embodiment in the configurations of the screen 210 and the screen stopper plate 220. The other configurations of the roller screen 200 can be the same as those of the first embodiment. In this embodiment, the configurations different from those of the first embodiment will be mainly described.

As shown in FIG. 9, the screen 210 and the screen stopper plate 220 are cut into a triangular shape with a wide gap between the bottom ends, forming triangular gaps 212, 224. Because the gap between adjacent screen stopper plates 220 is wide, even if the screen stopper plates 220 expand due to heat, the adjacent screen stopper plates 220 do not come into contact with each other, and no effect is caused. This makes it possible to prevent wrinkles in the screen 210.

The roller blind 200 of this embodiment can be manufactured in the same manner as the first embodiment. That is, the screen stopper plate 220 can be attached to the back surface 210b of the screen 210 in advance with staples 222, and then the screen 210 and the screen stopper plate 220 can be cut together between adjacent staples 222. Alternatively, multiple locations on the edge of the screen 210 can be cut into triangles in advance, and multiple screen stopper plates 220 of approximately trapezoidal shape corresponding to the edges of the screen 210 can be attached to the screen 210.

(Effects of the Second Embodiment)
As described above, according to this embodiment, the triangular gaps 212, 224 are formed in the screen stopper plate 220 adjacent to the lower end of the screen 210, so that even if the screen stopper plate 220 expands due to heat, the possibility of the expansion affecting the adjacent screen stopper plate 220 can be reduced. Therefore, the occurrence of wrinkles in the screen 210 can be suppressed.

Third Embodiment
The configuration of a roller screen 300 according to the third embodiment will be described with reference to Fig. 10. Fig. 10 is a diagram showing the state of a screen stopper plate 320 of the third embodiment. The roller screen 300 of this embodiment differs from the roller screen 100 of the first embodiment in the configurations of the screen 310 and the screen stopper plate 320. The other configurations of the roller screen 300 can be the same as those of the first embodiment. In this embodiment, the configurations different from those of the first embodiment will be mainly described.

As shown in FIG. 10, the screen 310 and the screen stopper plate 320 are cut so that equally spaced rectangular gaps 312, 324 are formed from the bottom end to the top end. Because the gap between adjacent screen stopper plates 320 is wide, even if the screen stopper plates 320 expand due to heat, the adjacent screen stopper plates 320 do not come into contact with each other, and no effect is caused. This makes it possible to suppress the occurrence of wrinkles in the screen 310.

The roller blind 300 of this embodiment can be manufactured in the same manner as the first embodiment. That is, the screen stopper plate 320 can be attached to the back surface 310b of the screen 310 in advance, and then the screen 310 and the screen stopper plate 320 can be cut together. Alternatively, multiple locations on the edge of the screen 310 can be cut into square shapes in advance, and multiple square-shaped screen stopper plates 320 corresponding to the edges of the screen 310 can be attached to the screen 310.

(Effects of the Third Embodiment)
As described above, according to this embodiment, the rectangular gaps 312, 324 are formed between the lower end of the screen 310 and the adjacent screen stop plate 320, so that even if the screen stop plate 320 expands due to heat, the possibility of the expansion affecting the adjacent screen stop plate 320 can be reduced. Therefore, the occurrence of wrinkles in the screen 310 can be suppressed.

(Fourth embodiment)
The configuration of a roll screen 400 according to the fourth embodiment will be described with reference to Fig. 11. Fig. 11 is a diagram showing the state of a screen stopper plate 420 of the fourth embodiment. The roll screen 400 of this embodiment differs from the roll screen 100 of the first embodiment in the configurations of the screen 410 and the screen stopper plate 420. The other configurations of the roll screen 400 can be the same as those of the first embodiment. In this embodiment, the configurations different from those of the first embodiment will be mainly described.

As shown in FIG. 11, a number of rectangular screen stop plates 420 are prepared in advance. A number of screen stop plates 420 are attached to the ends of the rear surface 410b of the screen 410 with staples 422 spaced at intervals 424 in the width direction. The screen 410 is not cut, but since there is a gap 424 between adjacent screen stop plates 420, the screen 410 is less susceptible to the effects of expansion and contraction of the screen stop plates 420 due to heat.

(Effects of the Fourth Embodiment)
As described above, according to this embodiment, since the interval 424 between adjacent screen stop plates 420 is wide, even if the screen stop plates 420 expand due to heat, the screen 410 is less susceptible to the influence of the expansion and contraction due to heat of the screen stop plates 420. Therefore, the occurrence of wrinkles in the screen 410 can be suppressed.

Although the preferred embodiment of the present invention has been described above with reference to the attached drawings, it goes without saying that the present invention is not limited to such an example. It is clear that a person skilled in the art can come up with various modified or revised examples within the scope of the claims, and it is understood that these also naturally fall within the technical scope of the present invention.

For example, in the first embodiment, the lower end of the screen 110 is attached to the bottom rail 140, but the same configuration can be used when the upper end of the screen is attached to the winding pipe. The same applies to the second to fourth embodiments.

In addition, in the first embodiment, the connecting support member is a screen stopper plate 120 that is a thin, rectangular flat plate, but the present invention is not limited to this example. Any design can be used as long as it is easy to release distortion of the screen caused by the expansion and contraction of the connecting support member and distortion of the screen caused by the attachment dependency of the fixing means, and prevents wrinkles from occurring.

In addition, in the first embodiment, the staple 122 is used as the fixing means for fixing the screen 110 and the screen stopper plate 120, but the present invention is not limited to this example. The fixing means can be of any design, such as using a pin badge or giving the screen stopper plate itself a clip function. The same applies to the second to fourth embodiments.

In addition, in the first embodiment, the multiple screen stop plates 120 are configured with a predetermined gap between adjacent screen stop plates 120, but the present invention is not limited to this example. Any design can be used as long as it is easy to release screen distortion caused by the expansion and contraction of the connecting support members and distortion caused by the attachment dependency of the fixing means, and wrinkles can be prevented. For example, adjacent screen stop plates may be in contact with each other.

In the first embodiment, the screen stopper plate 120 is configured so that the thickness direction and the bottom end of the side are curved, but the present invention is not limited to this example. Any design can be used as long as the corners of the connecting support member do not get caught on the connected member when connecting the connecting support member to the connected member, improving workability. For example, the connecting support member may have at least one of the thickness direction and bottom ends of adjacent side portions curved. Alternatively, the connecting support member may have a shape with rounded corners rather than a curved shape.

In the first embodiment, in processing procedure 4, the screen stopper plate 120 is cut together with the screen 110 in the vertical direction of the screen 110 at a position between adjacent staples 122 to form the slits 112, 124, but the present invention is not limited to this example. When cutting the screen stopper plate 120 in the vertical direction of the screen 110, the screen 110 does not have to be cut.
