Description

The present invention relates to blinds.

A conventional blind is shown in Japanese Utility Model Publication No. 63-24785 (Patent Document 1). In the blind disclosed in this document, 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 connecting support member attached to the tip of the screen is inserted between the partition plate and the protruding piece, preventing the screen from slipping out of the opening at the top of the weight bar. In this way, the screen can be connected to the weight bar.

Japanese Utility Model Publication No. 63-24785

However, in conventional blinds such as those disclosed in Patent Document 1, the plate-shaped connecting support member is attached to the tip of the screen with double-sided adhesive tape or staples, so when the connecting support member expands and contracts due to heat, the expansion and contraction can cause wrinkles in the screen, which is an issue.

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

To solve the above problems, the present invention provides a blind that includes a screen, a connecting member that is connected to at least one of the upper end and lower end of the screen, and a connecting support member that connects the screen to the connecting member, the connecting support member being attached to the screen by being inserted into a plurality of insertion portions that are provided in the width direction of the screen.

According to this configuration, the connecting support member is attached to the screen by inserting it through an insertion portion provided on the screen. In this way, the connecting support member is attached to the screen without using a fastening means such as double-sided adhesive tape or staples, so even if the connecting support member expands or contracts due to heat, the expansion or contraction of the connecting support member does not affect the screen. This makes it possible to prevent wrinkles from occurring on the screen.

The present invention can be applied in various ways. For example, the insertion portion may be a slit formed extending in the vertical direction of the screen, and the connecting support member may be inserted through the slit so as to alternately sew the front and rear surfaces of the screen. With this configuration, the connecting support member can be attached by being inserted through a slit formed in the screen, without using a fastening means such as double-sided adhesive tape or staples. In this way, since the screen is not fastened to the connecting support member, even if the connecting support member expands or contracts due to heat, the expansion or contraction of the connecting support member does not affect the screen. This makes it possible to prevent the screen from becoming wrinkled.

The slits may be formed at a predetermined height excluding the ends of the screen. Because the slits are formed at a predetermined height excluding the ends of the screen, the connecting support members can be attached simply by passing them through the slits, improving assembly.

The insertion portion may be a slit extending vertically from the end of the screen, and the connecting support member inserted through the slit may be supported by the end of the screen that is folded back. Since the slit is formed up to the end of the screen, it is easy to insert the connecting support member.

The insertion portion may also be a circular or polygonal hole. Since the insertion portion is large, it is easy to insert the connection support member.

The insertion portion may be provided separately from the screen on one surface of the screen. Because the insertion portion is separate from the screen, even if the connecting support member is inserted into the insertion portion, unevenness (wrinkles) due to the placement of the connecting support member is unlikely to occur on the screen. Also, the connecting support member can be attached to the screen simply by inserting it into the insertion portion along one surface of the screen, making it easy to install the screen.

The screen may be housed within the connected member for a predetermined length from the end of the insertion portion. Even if unevenness (wrinkles) of the screen are formed near the slit, the unevenness of the screen surface within a predetermined length range from the end of the insertion portion is housed within the connected member. This prevents the unevenness of the screen from being exposed to the outside.

The connection support member may be in the form of a thin plate or rod. The connection support member can be in any shape to match the shape of the insertion portion and the non-connected member.

According to the present invention, 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 does not affect the screen, and it is possible to provide a blind that can prevent the occurrence of wrinkles in 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 a roll screen (blind) 100 according to this embodiment will be described with reference to Fig. 1. Fig. 1 is a perspective view showing the overall configuration of the roll screen 100 according to this embodiment. As shown in Fig. 1, the roll screen 100 is configured to include a set frame 110, a winding pipe 120 rotatably supported by the set frame 110, a screen 130 suspended from the winding pipe 120 so as to be capable of being wound up and unwound, and a weight bar (connected member) 140 to which the lower end of the screen 130 is connected. Each component of the blind 100 will be described below.

(Set frame 110)
The set frame 110 is a member that supports the screen 130. As shown in Fig. 1, the set frame 110 is an elongated member that is fixed to a window frame (not shown) or the like via brackets 112. Side plates 114 are provided on both ends of the set frame 110.

(Winding pipe 120)
The winding pipe 120 supports the screen 130 so that it can be wound and unwound. As shown in FIG. 1 , one end of the winding pipe 120 is supported by one of the side plates 114 via a pulley 122, and the other end is rotatably supported by the other side plate 114. The winding pipe 120 and the pulley 122 rotate together. A loop-shaped ball chain 124 is wound around the pulley 122. The rotation of the pulley 122 is controlled by pulling down the front or rear side of the ball chain 124. Thus, the rotation of the winding pipe 120 is controlled.

(Screen 130)
1, the screen 130 has an upper end connected to the winding pipe 120 so as to be capable of being wound and unwound. The screen 130 rises when wound around the winding pipe 120, and falls when unwound from the winding pipe 120.

The configuration of the end of the screen 130 will be described with reference to Figures 2 and 3. Figure 2 is a perspective view showing the state in which the screen stopper plate (connecting support member) 132 is inserted into the slit 130a of the screen 130. Figure 3 is a view showing the state in which the screen stopper plate 132 is inserted into the slit 130a of the screen 130.

As shown in Figs. 2 and 3, a plurality of slits (insertion portions) 130a are provided in at least one of the vicinity of the upper end or the lower end of the screen 130 in the width direction. The slits 130a are formed to extend in the vertical direction at a predetermined height position excluding the ends of the screen 130. As shown by the arrow a in Fig. 2, a long screen stopper plate 132 is inserted into the slits 130a so as to alternately weave between the front and rear surfaces of the screen 130 and connect them. The screen stopper plate 132 is thin plate-shaped and is provided over the entire width of the screen 130. Note that although the screen stopper plate 132 is thin plate-shaped in this embodiment, it may be rod-shaped.

(Weight bar 140)
The weight bar 140 maintains the screen 130 in a tensed state by its weight. The weight bar 140 is attached to the lower end of the screen 130 as shown in FIG. 1. The configuration of the weight bar 140 will be described with reference to FIG. 4. FIG. 4 is a cross-sectional view showing the screen 130 connected to the weight bar 140. As shown in FIG. 4, the weight bar 140 is internally divided into two in the upper and lower direction, and the upper space is configured as a storage section 140a that stores the lower end of the screen 130. An opening 140b through which the screen 130 passes is formed in the upper part of the storage section 140a.

A screen stopper plate 132 connected to the screen 130 is placed in the storage section 140a through the opening 140b of the weight bar 140. The end of the screen 130 is folded back at one end of the slit 130a and placed on the upper surface side of the screen stopper plate 132.

The screen 130 on the other end side of the slit 130a is folded back to the upper surface side of the screen stopper plate 132 at the other end of the slit 130a and is led out through the opening 140b. In this way, a portion of a predetermined length from the other end side of the slit 130a is accommodated in the screen stopper plate 132. This portion is called the absorbing portion 130b. Depending on the thickness and material of the screen stopper plate 132, unevenness (wrinkles) may occur in the screen 130 near the end of the slit 130a, but even if unevenness (wrinkles) are formed in the screen 130, the absorbing portion 130b accommodates the unevenness of the screen 130 within the weight bar 140. This prevents the unevenness of the screen 130 from being exposed to the outside.

The screen 130 can be connected to the winding pipe (connected member) 120 in the same manner as when it is connected to the weight bar 140. The structure for connecting the screen 130 to the winding pipe 120 will be described with reference to FIG. 5. FIG. 5 is a cross-sectional view showing the state in which the screen 130 is connected to the winding pipe 120. The winding pipe 120 has a storage section 120a that stores the screen stopper plate 132, and an opening 120b formed on the outer periphery of the storage section 120a.

When connecting the screen 130 to the winding pipe 120, the screen stopper plate 132 connected to the screen 130 is placed in the storage section 120a through the opening 120b of the winding pipe 120. The end of the screen 130 is folded back at one end of the slit 130a and placed on the upper surface side of the screen stopper plate 132.

The screen 130 on the other end side of the slit 130a is folded back onto the upper surface side of the screen stopper plate 132 at the other end of the slit 130a and led out through the opening 120b. In this way, the part of the screen 130 housed in the housing section 120a from the other end side of the slit 130a to the opening 120b forms an absorbing section 130b to prevent the unevenness of the surface of the screen 130 formed near the slit 130a from being exposed to the outside.

(Effects of the First Embodiment)
As described above, according to this embodiment, the screen stopper plate 132 is attached to the screen 130 by being inserted through the slit 130a provided in the screen 130. In this way, the screen stopper plate 132 is attached to the screen 130 without using any fixing means such as double-sided adhesive tape or staples, so that even if the screen stopper plate 132 expands or contracts due to heat, the expansion or contraction of the screen stopper plate 132 does not affect the screen 130. This makes it possible to prevent wrinkles from occurring in the screen 130.

In addition, since the slits 130a are formed at a predetermined height position excluding the ends of the screen 130, the screen stopper plate 132 can be attached simply by passing it through the slits 130a. This improves assembly.

In addition, the absorbing portion 130b can prevent the unevenness of the surface of the screen 130 formed near the slit 130a from being exposed to the outside by containing it within the weight bar 140.

Second Embodiment
Next, the configuration of the roller blind 200 according to this embodiment will be described with reference to Fig. 6 and Fig. 7. Fig. 6 is a perspective view showing a state in which a screen stopper plate 232 is inserted into a slit 230a of a screen 230 of the roller blind 200 according to this embodiment. Fig. 7 is a view showing a state in which the screen stopper plate 232 is inserted into a slit 230a of the screen 230.

The roller blind 200 of this embodiment differs from the roller blind 100 of the first embodiment in the configuration of the screen 230. The rest of the configuration of the roller blind 200 is the same as in the first embodiment, and includes a set frame 110, a winding pipe 120, and a weight bar 140. In this embodiment, the configuration of the screen 230, which is the difference from the first embodiment, will be mainly described.

As shown in FIG. 6, the screen 230 has slits (insertion portions) 230a extending vertically from the ends of the screen 230. As shown by the arrow b in FIG. 6, the screen stopper plate (connecting support member) 232 passes through the slits 230a so as to alternately weave between the front and rear surfaces of the screen 230, as in the first embodiment.

As shown in FIG. 7, the screen stopper plate 232 is provided over the entire width of the screen 230. The ends of the screen 230 are folded back to cover the lower end of the screen stopper plate 232, as shown by arrows c and d in FIG. 7(b), to support the screen stopper plate 232.

(Effects of the Second Embodiment)
As described above, according to this embodiment, the slits 230a are formed up to the ends of the screen 230, so that the screen stopper plate 232 can be easily inserted therethrough.

Third Embodiment
Next, the configuration of the roller screen (blind) 300 according to this embodiment will be described with reference to Fig. 8. Fig. 8 is a perspective view showing a screen 330 and a screen stopper plate 332 of the roller screen 300 according to this embodiment.

The roller blind 300 of this embodiment differs from the roller blind 100 of the first embodiment in the configuration of the screen 330. The rest of the configuration of the roller blind 300 is the same as in the first embodiment, and includes a set frame 110, a winding pipe 120, and a weight bar 140. In this embodiment, the configuration of the screen 330, which is the difference from the first embodiment, will be mainly described.

As shown in FIG. 8, the screen 330 has a rectangular hole (insertion portion) 330a formed in place of the slit 130a of the first embodiment. As shown by the arrow e in the figure, a screen stopper plate (connection support member) 332 is inserted through the hole 330a in a manner similar to the first embodiment and connected to the front and back of the screen 330.

(Effects of the Third Embodiment)
As described above, according to this embodiment, by forming the hole 330a in a rectangular shape, the insertion portion through which the screen stopper plate 332 is inserted becomes large. Therefore, it is easier to insert the screen stopper plate 332.

Fourth Embodiment
Next, the configuration of the roller blind 400 according to this embodiment will be described with reference to Fig. 9. Fig. 9 is a perspective view showing a screen 430 and a screen stopper plate 432 of the roller blind 400 according to this embodiment.

The roller blind 400 of this embodiment differs from the roller blind 100 of the first embodiment in the configuration of the screen 430. The rest of the configuration of the roller blind 400 is the same as in the first embodiment, and includes a set frame 110, a winding pipe 120, and a weight bar 140. In this embodiment, the configuration of the screen 430, which is the difference from the first embodiment, will be mainly described.

As shown in FIG. 9, the screen 430 is provided with a string-like portion (insertion portion) 430a that is connected to the screen 430 like a belt loop, instead of the slit 130a in the first embodiment. The string-like portion 430a is provided on only one side of the screen 430. The screen stopper plate (connection support member) 432 is connected to the screen 430 by inserting the string-like portion 430a like a belt, as shown by the arrow f in the figure.

(Effects of the Fourth Embodiment)
As described above, according to this embodiment, since the string-like portion 430a is separate from the screen 430, even if the screen stopper plate 432 is inserted through the string-like portion 430a, wrinkles are unlikely to occur in the screen.

The screen fixing plate 432 can be attached to the screen 430 simply by inserting the string-shaped portion 430a along one side of the screen 430, making it easy to install the screen 430.

Fifth Embodiment
In the above first to fourth embodiments, a roll screen has been described as an example, but the present invention can also be applied to a pleated screen. An example in which the present invention is applied to a pleated screen will be described with reference to Fig. 10. Fig. 10 is a cross-sectional view showing a state in which the screen 530 of the pleated screen 500 of this embodiment is connected to a bottom rail 540.

The configuration of the pleated screen (blind) 500 of this embodiment will be described below. Mainly, the configuration that connects the screen 530 and the bottom rail (connected member) 540, which is a characteristic configuration of this embodiment, will be described. The rest of the configuration of the pleated screen 500 can be the same as that of a general pleated screen, so the description will be omitted.

As shown in FIG. 10, the screen 530 is bent in an accordion-like shape to form pleats. The bottom pleat of the screen 530 has a slit (insertion portion) 530a formed therein, similar to the slit 130a in the first embodiment. A screen stopper plate (connecting support member) 532 is connected to the slit 530a, similar to the first embodiment.

The bottom rail 540 has a storage section 540a that stores the screen stopper plate 532, and an opening 540b formed on the outer periphery of the storage section 540a. The screen stopper plate 532 connected to the screen 530 is placed in the storage section 540a through the opening 540b of the bottom rail (connected member) 540. An end of the screen 530 is folded back at one end of the slit 530a and placed on the upper surface side of the screen stopper plate 532.

The screen 530 on the other end side of the slit 530a is folded back onto the upper surface side of the screen stopper plate 532 at the other end of the slit 530a and led out through the opening 540b. In this way, a portion of a predetermined length from the other end side of the slit 530a (the absorbing portion 530b) is housed within the screen stopper plate 532. This absorbing portion 530b prevents the unevenness of the surface of the screen 530 formed near the slit 530a from being exposed to the outside.

The lower end of a lifting cord 550 for raising and lowering the screen 530 is connected to the bottom of the bottom rail 540 by a cord bolt 542. The upper end of the lifting cord 550 passes through the screen stopper plate 532 and the screen 530 and is introduced into a head rail (not shown).

(Effects of the Fifth Embodiment)
As described above, according to this embodiment, the pleated screen 500 has the screen stopper plate 532 attached to the screen 530 without using any fastening means such as double-sided adhesive tape or staples, so that even if the screen stopper plate 532 expands or contracts due to heat, the expansion or contraction of the screen stopper plate 532 does not affect the screen 530. This makes it possible to prevent wrinkles from forming on the screen 530. In addition, the present embodiment has other effects similar to those of the first embodiment.

Furthermore, the pleated screen 500 of this embodiment can have an insertion portion configured in the same way as in the second to fourth embodiments. In that case, it has the same effects as the second to fourth embodiments.

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 above embodiment, the blinds are roller blinds and pleated screens, but the present invention is not limited to this example, and any design can be used as long as the blinds have a configuration in which the screen is connected to the connecting member via a screen stopper plate.

In the above embodiment, the weight bar, winding pipe, and bottom rail are given as examples of connected members to which the screen is connected, but the present invention is not limited to these examples. Any connected member can be used as long as the screen is connected via a screen stopper plate. For example, it may be the head rail of a pleated screen, or the middle rail of a blind that has two screens, one above the other.

In addition, in the third embodiment, the shape of the hole 330a is rectangular, but the present invention is not limited to this example, and any shape can be used as long as it is easy to insert the screen stopper plate. For example, the hole may be circular or any polygonal shape.

In addition, in the first embodiment, the screen 130 is configured such that a predetermined length from the other end of the slit 130a is housed within the screen stopper plate 132, but the present invention is not limited to this example. Any design can be used as long as the unevenness of the screen surface formed near the slit is prevented from being exposed to the outside. The same applies to the second to fifth embodiments.

In addition, in the first embodiment, the connecting support member is a thin screen stopper plate 132, but the present invention is not limited to this example. Any design can be used as long as it can be inserted into the insertion portion. For example, it may be rod-shaped. The same applies to the second to fifth embodiments.
