Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the conventional roll screen as disclosed in Patent Document 1, the tip of the screen is attached to the connecting support member via double-sided tape. Therefore, when the temperature of the window surface to which the roll screen is attached becomes high due to solar radiation heat, the connecting support member expands and contracts due to the heat, and the screen wrinkles due to the expansion and contraction. In addition, the 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 member that contracts due to heat is used as the connecting support member, the fixed parts by the staples will be pulled together, and if a member that expands due to heat is used as the connecting support member, the fixed parts by the staples will be pushed together, and there is a problem that wrinkles will be more noticeable due to the strong load being applied to some parts.

[0005] The present invention has been made in consideration of such problems, and its object is to provide a roll screen and a method for manufacturing a roll screen in which, 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 wrinkles in the screen can be prevented. [Means for solving the problem]

[0006] In order to solve the above problems, according to a first aspect of the present invention, there is provided a roll screen comprising a screen for shielding 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, characterized in that the connecting support members are arranged in multiple rows in the width direction of the screen.

[0007] According to such a configuration, since the connecting support members are attached in a separated state in the width direction of the screen, it becomes easier to release the distortion of the screen due to the expansion and contraction of the connecting support members and the distortion of the screen due to the attachment dependence 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 do not affect the screen, and the generation of wrinkles on the screen can be prevented.

[0008] The present invention can be applied in various ways. For example, the plurality of the connecting support members may be fixed to the end portions of the screen via one fixing means each. According to such a configuration, since the connecting support members are separated between the fixing means, it becomes easier to release the attachment dependence of the fixing means, that is, the distortion of the screen due to a load being applied to the attachment portion, and the effect of preventing the generation of wrinkles can be enhanced.

[0009] Also, a predetermined gap may be provided between adjacent ones of the plurality of the connecting support members. According to such a configuration, since the distortion of the screen can be released evenly, the effect of preventing the generation of wrinkles can be enhanced. Further, even if the connecting support members are made of a material that expands with heat, it is possible to prevent adjacent connecting support members from interfering with each other.

[0010] Also, the gap may be in a slit shape formed by cutting the connecting support member in the vertical direction of the screen. According to such a configuration, it is advantageous in that the processing of the connecting support member is easy.

[0011] Also, the screen may be separated between adjacent ones of the connecting support members. According to such a configuration, the influence on the screen due to the expansion and contraction of the connecting support members is further reduced.

[0012] Further, at least one of the thickness direction of the adjacent side portions and the lower end of the plurality of connecting support members may be formed in a curved surface shape. According to such a configuration, when connecting the connecting support member to the member to be connected, the corners of the connecting support member are not caught by the member to be connected, so the workability is improved.

[0013] Further, 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 member to be connected connected to at least one end portion of an upper end portion or a lower end portion of the screen, and a connecting support member for connecting the screen to the member to be connected. In the method for manufacturing a roll screen, one of the connecting support members is attached to the end portion via a plurality of fixing means, and the connecting support member is cut together with the screen between the plurality of fixing means.

[0014] According to such a configuration, since the connecting support member can be processed together with the screen after being attached to the screen, the productivity in manufacturing the roll screen according to the first aspect of the present invention can be improved.

Effects of the Invention

[0015] 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 occurrence of wrinkles on the screen because even if the connecting support member attached to the screen expands and contracts due to heat, the expansion and contraction of the connecting support member do not affect the screen. Other effects of the present invention will also be described in the embodiments for carrying out the invention described later.

Mode for Carrying Out the Invention

[0017] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and the drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant explanations are omitted.

[0018] (First Embodiment) The overall configuration of the roller 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 roller screen 100 of this embodiment. FIG. 2 is a front view showing the mounting state of the screen stop plate 120. As shown in FIG. 1, the roller screen 100 includes a screen 110 that shields an opening, a screen stop plate (connecting support member) 120 attached to the ends of the screen 110, a winding pipe (member to be connected) 130 connected to the upper end of the screen 110 via a fixing plate (not shown), and a bottom rail (member to be connected) 140 connected to the lower end of the screen 110 via the screen stop plate 120. And a plurality of screen stop plates 120 are arranged side by side 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 stop plate 120 may be used instead of the above-described fixing plate (not shown). Specifically, the upper end of the screen 110 may be connected to the winding pipe 130 by locking the screen stop plate 120 attached to the upper end of the screen 110 into a groove (not shown) of the winding pipe 130. Hereinafter, each component of the roller screen 100 will be described.

[0019] (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 wound and unwound. The screen 110 rises by being wound around the winding pipe 130 and descends by being 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 up and down movement is guided by the guide rails 150.

[0020] (Screen stop plate 120) The screen fixing plate 120 connects the screen 110 to the winding pipe 130 or the bottom rail 140. Hereinafter, the screen fixing plate 120, which is a characteristic configuration of the present embodiment, will be described with reference to FIG. 2.

[0021] As shown in FIG. 2, the screen fixing plate 120 is attached to the end of the back surface 110b of the screen 110, and a plurality of the screen fixing plates 120 are arranged side by side in the width direction of the screen 110. The screen fixing plate 120 is a thin rectangular flat plate. The side portion and the lower end of the screen fixing plate 120 may be formed in a curved surface shape. According to such a configuration, when the screen fixing plate 120 is connected to the winding pipe 130 or the bottom rail 140, the corners of the screen fixing plate 120 are not caught by the bottom rail 140, so that the work is easy to perform.

[0022] (Winding pipe 130) The winding pipe 130 supports the screen 110 so that it can be wound 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 a long set frame 160 fixed to the window frame WF via brackets 162.

[0023] 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 the pulley 132 rotate integrally. An operation chain 134 formed in a loop shape by a connector 136 is wound around the pulley 132. By pulling down the front side or the rear side of the operation chain 134, the rotation of the pulley 132 is operated, and the rotation of the winding pipe 130 is operated.

[0024] (Bottom rail 140) The bottom rail 140 holds the screen 110 in a tensioned state by its weight. As shown in FIG. 1, the bottom rail 140 is attached to the lower end of the screen 110. Bottom rail caps 142 are provided at both ends of the bottom rail 140. The bottom rail caps 142 are inserted into the guide rail 150.

[0025] 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 in the longitudinal direction of the bottom rail 140. The bottom rail cushioning material 144 is made of an elastically deformable material and deforms to be in close contact with the bottom of the window frame WF at the lowest descending position of the bottom rail 140.

[0026] The configuration of each part of the roll screen 100 has been described above. Hereinafter, the attachment state of the screen stop plate 120 to the screen 110 will be described with reference to FIG. 3. FIG. 3 is a cross-sectional view showing the attachment state of the screen stop 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.

[0027] As shown in FIG. 3, the screen stop plate 120 is attached to the screen 110 by a double-sided tape 170 and is fixed to the back surface 110b of the screen 110 via one staple (fixing means) 122 each. The staple 122 is driven approximately at the center in the height direction of the screen stop plate 120. The driving direction of the staple 122 is from the front surface 110a to the back surface 110b of the screen 110 as indicated by the arrow a in FIG. 3(a).

[0028] The attachment state of the screen stop plate 120 to the screen 110 has been described above. Next, the attachment and processing procedures of the screen stop plate 120 to the screen 110 will be described with reference to FIG. 4. FIG. 4 is a front view showing the attachment and processing procedures of the screen stop plate 120, where (a) is a view showing step 1, (b) is a view showing step 2, (c) is a view showing step 3, and (d) is a view showing step 4.

[0029] Step 1: As shown in FIG. 4(a), turn the back surface 110b of the screen 110 upward. Step 2: As shown in FIG. 4(b), place a long screen stop plate 120 extending over the entire length in the width direction of the screen 110 on the lower end of the back surface 110b of the screen 110. At this time, temporarily fix the back surface 110b of the screen 110 and the screen stop plate 120 with a double-sided tape 170. Step 3: As shown in FIG. 4(c), fix multiple locations of the screen stop plate 120 to the screen 110 with staples 122. Step 4: As shown in FIG. 4(d), at the positions between adjacent staples 122, divide the screen stop plate 120 together with the screen 110 in the vertical direction of the screen 110 to form slits 112 and 124.

[0030] In this way, a plurality of screen stop plates 120 can be arranged side by side in the width direction at the end of the screen 110.

[0031] The attachment and processing procedures of the screen stop plate 120 to the screen 110 have been described above. Next, the state of the screen 110 attached to the bottom rail 140 will be described with reference to FIGS. 5 and 6. FIG. 5 is a cross-sectional view of a portion corresponding to the B-B cross-section of FIG. 2, showing the state where the screen stop plate 120 is attached to the bottom rail 140. FIG. 6 is a view showing the state of the screen 110 in the vicinity of the bottom rail 140.

[0032] As shown in FIG. 5, the screen 110 is received in the bottom rail 140 from the side in a state where the screen stopper plate 120 is folded back 180 degrees toward the back surface 110b side. By folding the screen stopper plate 120 back 180 degrees in the direction of the back surface 110b, the screen stopper plate 120 is hidden by the screen 110 and cannot be seen from the front surface 110a. As shown in FIG. 6, the screen 110 is attached so that all the screen stopper plates 120 are received in the bottom rail 140.

[0033] As shown in FIG. 5, the upper part of the screen stopper plate 120 protrudes upward from the front side of the bottom rail 140 but is hidden by the front surface 110a of the screen 110. Also, as shown in FIG. 6, the screen stopper plate 120 is attached in a state of being separated at every one staple 122 in the width direction of the screen 110. For this reason, it becomes easy to release the distortion of the screen 110 due to the expansion and contraction of the screen stopper plate 120 and the distortion of the screen 110 due to the dependence on the attachment of the staple 122, and the generation of wrinkles in the screen 110 is prevented.

[0034] Here, the conventional roll screen 500 will be described with reference to FIGS. 7 and 8. FIG. 7 is a view showing a state in which the conventional screen stopper plate 520 is attached. FIG. 8 is a view showing the state of the screen 510 near the bottom rail 540 when the conventional screen stopper plate 520 is used.

[0035] At the lower end of the back surface 510b of the screen 510, as shown in FIG. 7, a long screen retaining plate 520 extending over the entire length in the width direction of the screen 510 is attached by staples 522. As shown in FIG. 8, the screen 510 is attached to the bottom rail 540 by the screen retaining plate 520. Since the screen retaining plate 520 is connected to the screen 510 at a plurality of locations, when the vicinity of the window to which the roll screen 500 is attached becomes hot due to solar heat, the screen retaining plate 520 expands and contracts due to heat, and wrinkles 510c are generated on the screen 510 due to the influence of the expansion and contraction.

[0036] (Effect of the First Embodiment) As described above, according to the present embodiment, since the screen retaining plate 120 is attached in a state of being separated in the width direction of the screen 110, it becomes easier to release the distortion of the screen 110 due to the expansion and contraction of the screen retaining plate 120 and the distortion of the screen 110 due to dependence on the attachment of the staples 122. Therefore, even if the screen retaining plate 120 attached to the screen 110 expands and contracts due to heat, the expansion and contraction of the screen retaining plate 120 does not affect the screen 110, and the generation of wrinkles on the screen 110 can be prevented.

[0037] In addition, since the screen retaining plates 120 are separated between the respective staples 122, it becomes easier to release the distortion of the screen 110 caused by the staples 122, and the effect of preventing the generation of wrinkles can be enhanced.

[0038] In addition, even if the screen retaining plate 120 is made of a material that expands when heated, it is possible to prevent adjacent screen retaining plates 120 from interfering with each other.

[0039] In addition, since the gap is in the shape of a slit formed by cutting the screen retaining plate 120 in the vertical direction of the screen 110, it is advantageous in that the screen retaining plate 120 can be easily processed.

[0040] In addition, since the screen 110 is separated between adjacent screen stoppers 120, the influence on the screen 110 due to the expansion and contraction of the screen stopper 120 is further reduced.

[0041] Moreover, since the screen 110 can be processed as a whole after the screen stopper 120 is attached to the screen 110, the productivity during manufacturing can be increased.

[0042] (Second Embodiment) The configuration of the roll screen 200 according to the second embodiment will be described with reference to FIG. 9. FIG. 9 is a diagram showing the state of the screen stopper 220 of the second embodiment. The roll screen 200 of this embodiment is different from the roll screen 100 of the first embodiment in the configuration of the screen 210 and the screen stopper 220. Other configurations of the roll screen 200 can be the same as those of the first embodiment. In this embodiment, the description will focus on the configurations different from those of the first embodiment.

[0043] As shown in FIG. 9, the screen 210 and the screen stopper 220 are cut into a triangular shape with a wide interval at the lower end, and triangular gaps 212 and 224 are formed. Since the interval between adjacent screen stoppers 220 is wide, even if the screen stopper 220 expands due to heat, adjacent screen stoppers 220 do not come into contact with each other and no influence is caused. Therefore, the generation of wrinkles on the screen 210 can be suppressed.

[0044] The roll screen 200 of this embodiment can be manufactured in the same manner as in the first embodiment. That is, after the screen fixing plate 220 is preliminarily attached to the back surface 210b of the screen 210 with staples 222, the screen 210 and the screen fixing plate 220 can be cut together between adjacent staples 222. Further, a plurality of locations at the ends of the screen 210 may be cut into a triangular shape in advance, and a plurality of substantially trapezoidal screen fixing plates 220 corresponding to the ends of the screen 210 may be attached to the screen 210.

[0045] (Effect of the second embodiment) As described above, according to this embodiment, since the triangular gaps 212 and 224 are formed between the lower end of the screen 210 and the adjacent screen fixing plate 220, even if the screen fixing plate 220 expands due to heat, the possibility of affecting the adjacent screen fixing plate 220 can be reduced. Therefore, the occurrence of wrinkles in the screen 210 can be suppressed.

[0046] (Third embodiment) The configuration of the roll screen 300 according to the third embodiment will be described with reference to FIG. 10. FIG. 10 is a view showing the state of the screen fixing plate 320 of the third embodiment. The roll screen 300 of this embodiment is different from the roll screen 100 of the first embodiment in the configuration of the screen 310 and the screen fixing plate 320. Other configurations of the roll screen 300 can be the same as those of the first embodiment. In this embodiment, the description will focus on the configuration different from the first embodiment.

[0047] As shown in FIG. 10, the screen 310 and the screen stopper plate 320 are cut so that square gaps 312 and 324 are formed at equal intervals from the lower end to the upper end. Since the interval between adjacent screen stopper plates 320 is wide, even if the screen stopper plate 320 expands due to heat, adjacent screen stopper plates 320 do not come into contact with each other and no influence is caused. Therefore, the generation of wrinkles in the screen 310 can be suppressed.

[0048] The roll screen 300 of the present embodiment can be manufactured in the same manner as in the first embodiment. That is, after the screen stopper plate 320 is attached to the back surface 310b of the screen 310 in advance, the screen 310 and the screen stopper plate 320 can be cut together to form the roll screen 300. Alternatively, a plurality of locations at the ends of the screen 310 may be cut into a square shape in advance, and a plurality of square screen stopper plates 320 corresponding to the ends of the screen 310 may be attached to the screen 310.

[0049] (Effect of the Third Embodiment) As described above, according to the present embodiment, since the square gaps 312 and 324 are formed in the lower end of the screen 310 and the adjacent screen stopper plate 320, even if the screen stopper plate 320 expands due to heat, the possibility of affecting the adjacent screen stopper plate 320 can be reduced. Therefore, the generation of wrinkles in the screen 310 can be suppressed.

[0050] (Fourth Embodiment) The configuration of the roll screen 400 according to the fourth embodiment will be described with reference to FIG. 11. FIG. 11 is a view showing the state of the screen stopper plate 420 of the fourth embodiment. The roll screen 400 of the present embodiment is different 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 the present embodiment, the description will focus on the configuration different from the first embodiment.

[0051] As shown in FIG. 11, a plurality of screen fixing plates 420 having a rectangular shape in advance are prepared. At the end of the back surface 410b of the screen 410, a plurality of screen fixing plates 420 are attached by staples 422 with a space 424 in the width direction. Although the screen 410 is not cut, since there is a space 424 between adjacent screen fixing plates 420, the screen 410 is less likely to be affected by the expansion and contraction due to the heat of the screen fixing plate 420.

[0052] (Effect of the Fourth Embodiment) As described above, according to the present embodiment, since the space 424 between adjacent screen fixing plates 420 is wide, even if the screen fixing plate 420 expands due to heat, the screen 410 is less likely to be affected by the expansion and contraction due to the heat of the screen fixing plate 420. Therefore, the generation of wrinkles in the screen 410 can be suppressed.

[0053] As described above, the preferred embodiments of the present invention have been described with reference to the accompanying drawings. Needless to say, the present invention is not limited to such examples. It is obvious that those skilled in the art can conceive of various modification examples or correction examples within the scope described in the claims, and it is naturally understood that they also belong to the technical scope of the present invention.

[0054] For example, in the above-described first embodiment, the configuration in which the lower end of the screen 110 is attached to the bottom rail 140 has been described. However, when the upper end of the screen is attached to the winding pipe, the same configuration can be adopted. The same applies to the second to fourth embodiments.

[0055] In addition, in the above-described first embodiment, the connecting support member is the screen fixing plate 120 which is a thin rectangular flat plate. However, the present invention is not limited to this example. Any design can be adopted as long as it can easily release the distortion of the screen due to the expansion and contraction of the connecting support member and the distortion of the screen due to the dependence on the mounting of the fixing means, and can prevent the generation of wrinkles.

[0056] In addition, in the above-described first embodiment, staples 122 were used as the fixing means for fixing the screen 110 and the screen stopper plate 120. However, the present invention is not limited to this example. As the fixing means, any design can be adopted, such as using pin badges or providing the screen stopper plate itself with a clip function. The same applies to the second to fourth embodiments.

[0057] In addition, in the above-described first embodiment, the plurality of screen stopper plates 120 are configured such that a predetermined gap is provided between adjacent screen stopper plates 120. However, the present invention is not limited to this example. Any design can be adopted as long as it can easily release the distortion of the screen due to the expansion and contraction of the connection support member and the distortion of the screen due to the attachment dependence of the fixing means, and can prevent the generation of wrinkles. For example, adjacent screen stopper plates may be in contact with each other.

[0058] In addition, in the above-described first embodiment, the screen stopper plate 120 is configured such that the thickness direction of the side portion and the lower end are formed in a curved surface shape. However, the present invention is not limited to this example. Any design can be adopted as long as the corners of the connection support member are not caught by the connected member when the connection support member is connected to the connected member, and the workability is improved. For example, at least one of the thickness direction of the adjacent side portions and the lower end of the connection support member may be formed in a curved surface shape. Also, instead of a curved surface shape, a shape with rounded corners may be used.

[0059] In addition, in the above-described first embodiment, in the processing procedure 4, the screen stopper plate 120 is divided in the vertical direction of the screen 110 together with the screen 110 at a position between adjacent staples 122 to form the slits 112 and 124. However, the present invention is not limited to this example. When the screen stopper plate 120 is divided in the vertical direction of the screen 110, the screen 110 does not have to be divided.
