Description

Technical Field

[0001] The present invention relates to a support device for a blind and a blind.

Background Art

[0002] As a conventional support device for a blind, there is one disclosed in Japanese Patent Application Laid-Open No. 8-319782 (Patent Document 1). The support device for a blind disclosed in this Patent Document 1 is used for a roll screen, and includes a mounting bar fixed to a fixed surface such as a ceiling via a bracket, a roll pipe having a fixed shaft rotatably supported by side brackets at both ends of the mounting bar, and a fall prevention mechanism for the roll pipe. The fall prevention mechanism includes a holding plate fitted non-rotatably to the fixed shaft on one end side of the roll pipe, a wire having one end connected to the holding plate, and a spring having one end connected to the other end of the wire and the other end locked to the mounting bar. When the fixed shaft comes off from the side bracket, the holding plate is configured to be pressed against the end face of the roll pipe by the elastic force of the spring.

[0003] According to such a configuration, even if the fixed shaft of the roll pipe comes off from the side bracket, the roll pipe can be supported so as not to fall, and the rotation of the roll pipe can be restricted.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, while the above blind support device can prevent the roll pipe from falling off when it detaches from the side bracket, it cannot address the problem of the mounting bar, i.e., the poor attachment of the support member of the blind to the bracket, or the fall of the support member itself during the operation of attaching the support member to the bracket. Therefore, there has been a problem that a blind support device with improved safety is required.

[0006] Therefore, the present invention has been made in view of such problems, and its object is to provide a blind support device and a blind with improved safety.

Means for Solving the Problems

[0007] In order to solve the above problems, according to the present invention, there is provided a blind support device for supporting a blind fixed to a fixing surface by a bracket, comprising a fixture for a support member attached to a support member supported by the bracket, and a connecting member for connecting the fixture for the support member to the fixing surface, and characterized in that the connection between the support member and the fixing surface can be maintained in a non-fixed state in which the support member is not fixed to the fixing surface by the bracket.

[0008] According to such a configuration, even in a non-fixed state where the support member is not fixed to the fixing surface by the bracket, the connection between the support member and the fixing surface can be maintained, so that safety can be further improved.

[0009] The present invention can be applied in various ways. For example, the connecting member may be connected to the fixing surface via a fixture for the fixing surface attached to the fixing surface. According to such a configuration, the connecting member can be connected at an arbitrary position, so that the workability is improved.

[0010] Further, the connecting member may be a linear member having a slack allowance in a fixed state where the support member is fixed to the fixing surface by the bracket. According to such a configuration, for example, a connecting member such as a wire or a cord can be used to connect the support member fixture and the fixing surface, so it is inexpensive and excellent in workability during assembly. It is also advantageous in that there is no need to increase the size of the device.

[0011] Further, the support member fixture may be attached so as to surround the periphery of the support member. According to such a configuration, the blind can be more reliably supported by the support member fixture.

[0012] Further, the support member fixture includes a first plate member that surrounds from one surface on the front and rear sides of the support member to the lower surface, and a second plate member that surrounds from the other surface on the front and rear sides of the support member to the upper surface, and is configured by overlapping the first plate member and the second plate member. The first plate member and the second plate member may be members having the same shape. According to such a configuration, since the support member fixture can be retrofitted to the support member, the blind support device can be made an optional component that can be attached as needed. In addition, since the first plate member and the second plate member that constitute the support member fixture can be made of the same component, it is also advantageous in terms of parts management.

[0013] Further, the support member fixture may be attached to the upper end portion of the support member. According to such a configuration, the support member fixture can be attached with good design. It is also particularly advantageous in a blind in which a shielding material moves along the longitudinal direction of the support member, such as a vertical blind.

[0014] Further, the fixture for the support member may have a connecting portion to which one end of the connecting member can be connected on at least one of one side and the other side in the front-rear direction of the support member. According to such a configuration, since the connecting member is connected to the fixture for the support member at a position where it does not interfere with the shielding material of the blind, it is possible to prevent the shielding material from being damaged due to interference with the connecting member or generating frictional noise due to interference during lifting and lowering.

[0015] Further, it may be a blind including the support device for the blind. According to such a configuration, the blind can be supported even if the support member is not fixed to the fixing surface by the bracket.

[0016] Further, it further includes a winding pipe rotatably supported by the support member, a screen having one end connected to the winding pipe so as to be wound and unwound, and a weight bar connected to the other end of the screen, and the fixture for the support member may have a connecting portion to which one end of the connecting member can be connected at the upper part on the rear side of the support member. According to such a configuration, since the connecting portion is provided at a position where it does not restrict the upward movement of the weight bar when the screen is wound, it is possible to prevent the screen from being unable to be raised to the upper limit position due to the provision of the support device for the blind.

[0017] Further, it further includes a winding pipe rotatably supported by the support member, a screen having one end connected to the winding pipe so as to be wound and unwound, and a weight bar connected to the other end of the screen, and the support member may be composed of a set frame fixed to the fixing surface by the bracket and side brackets provided at both ends of the set frame for rotatably supporting the winding pipe. According to such a configuration, when the fixture for the support member is slidably attached to the support member in the longitudinal direction, it is possible to prevent the fixture for the support member from coming off from the end of the support member.

Effects of the Invention

[0018] According to the support device for blinds and the blinds of the present invention, safety can be further improved. Other effects of the present invention will also be described in the mode for carrying out the invention described later.

Mode for Carrying Out the Invention

[0020] With reference to the attached drawings below, preferred embodiments of the present invention will be described in detail. In this specification and the drawings, for components having substantially the same functional configuration, the same reference numerals are given to omit redundant description.

[0021] (First Embodiment) The configuration of the roll screen 10 (blind) according to the first 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 10 of the first embodiment. FIG. 2 is a perspective view of the roll screen 10 as seen from above.

[0022] As shown in FIGS. 1 and 2, the roll screen 10 of the present embodiment includes a bracket 12 for fixing the roll screen 10 to the ceiling CE (fixed surface), and a support device 100 (support device for blind) for supporting the roll screen 10. Note that the fixed surface for fixing the roll screen 10 may be a window frame, a wall surface, or the like. Hereinafter, each component of the roll screen 10 will be described in detail.

[0023] The roll screen 10 is supported by the bracket 12, and a set frame 14 (support member) extending over the entire longitudinal length of the roll screen 10 is supported by the bracket 12 and fixed to the ceiling CE. A winding pipe 16 is rotatably supported by side brackets 15 provided at both ends of the set frame 14. One end of the screen 18 is connected to the winding pipe 16 so as to be windable and unwindable. A weight bar 20 is connected to the other end of the screen 18. The roll screen 10 can have the same configuration as a general roll screen.

[0024] (Support Device 100) The overall configuration of the roll screen 10 has been described above. Next, the configuration of the support device 100, which is a characteristic configuration of the present embodiment, will be described with reference to FIGS. 3 to 5 in addition to FIGS. 1 and 2. FIG. 3 is a schematic cross-sectional view taken along line A-A of FIG. 1. FIG. 4 is a perspective view of the support device 100. FIG. 5 is an exploded perspective view of the support device 100.

[0025] The support device 100 is configured to maintain the connection between the set frame 14 and the ceiling CE in a non-fixed state where the set frame 14 is not fixed to the ceiling CE by the bracket 12. As shown in FIGS. 1 and 2, the support device 100 includes a set frame fixture 110 (support member fixture) attached to the set frame 14 supported by the bracket 12, a wire 120 (connecting member) that connects the set frame fixture 110 to the ceiling CE, and a ceiling fixture 130 (fixed surface fixture) for connecting the wire 120 to the ceiling CE.

[0026] (Set frame fixture 110) As shown in FIG. 3, the set frame fixture 110 is attached so as to surround the periphery of the set frame 14. The set frame fixture 110 includes a first plate member 111 that surrounds from one side surface in the front and rear of the set frame 14 to the lower surface, and a second plate member 112 that surrounds from the other side surface in the front and rear of the set frame 14 to the upper surface, and is configured by overlapping the first plate member 111 and the second plate member 112. The first plate member 111 and the second plate member 112 are members having the same shape.

[0027] As shown in FIGS. 4 and 5, the first plate member 111 and the second plate member 112 are composed of strip-shaped surrounding portions 111a and 112a that are bent in a substantially L shape along the shape of the set frame 14, short-side connecting pieces 111b and 112b that project in the front-rear direction from the tips of the short sides of the surrounding portions 111a and 112a, and long-side connecting pieces 111c and 112c that project in the front-rear direction from the tips of the long sides of the surrounding portions 111a and 112a. Each of the connecting pieces 111b, 111c, 112b, and 112c is inclined in the vertical direction at the same angle. The short-side connecting pieces 111b and 112b are inclined so as to form an acute angle with the short side, and the long-side connecting pieces 111c and 112c are inclined so as to form an obtuse angle with the long side.

[0028] When the first plate member 111 and the second plate member 112 are assembled to the set frame 14, as shown in FIG. 4, the short-side connecting piece 111b and the long-side connecting piece 112c, and also the short-side connecting piece 112b and the long-side connecting piece 111c, are configured to overlap each other. The short-side connecting piece 111b and the long-side connecting piece 112c are inclined obliquely downward, and the short-side connecting piece 112b and the long-side connecting piece 111c are inclined obliquely upward.

[0029] As shown in FIG. 5, screw holes 111d and 112d are formed in the short-side connecting pieces 111b and 112b. Also, insertion holes 111e and 112e are formed in the long-side connecting pieces 111c and 112c. When the short-side connecting pieces 111b and 112b and the long-side connecting pieces 112c and 111c overlap each other, the screw holes 111d and 112d and the insertion holes 112e and 111e overlap. The short-side connecting pieces 111b and 112b and the long-side connecting pieces 112c and 111c are screwed together with wire connecting screws 114 with washers and front screws 113 by overlapping the screw holes 111d and 112d and the insertion holes 112e and 111e.

[0030] When the fixture 110 for the set frame is attached to the set frame 14, as shown in FIG. 3, since the short-side connecting piece 111b and the long-side connecting piece 112c are inclined obliquely downward, a gap that widens toward the rear end is formed between the short-side connecting piece 111b and the long-side connecting piece 112c and the ceiling CE. Therefore, the wire connecting screw 114 can be easily attached. One end of the wire 120 is connected to the wire connecting screw 114 of the fixture 110 for the set frame.

[0031] (Wire 120) The wire 120 is a connecting member for connecting the fixture 110 for the set frame to the ceiling CE. As shown in FIG. 5, one end of the wire 120 is connected to the wire connecting screw 114 of the fixture 110 for the set frame, and the other end is connected to a wire connecting screw 131 (to be described later) of the ceiling fixture 130. When the ceiling fixture 130 is attached to the ceiling CE, as shown in FIG. 4, the wire 120 has a slack allowance. In this embodiment, the connecting member is the wire 120, but other linear members such as a cord may be used.

[0032] (Ceiling fixture 130) The ceiling fixture 130 is for connecting the wire 120 to the ceiling CE. As shown in FIG. 5, the ceiling fixture 130 includes a mounting portion 130a for attaching the ceiling fixture 130 to the ceiling CE and a wire connecting piece 130b for attaching the wire 120 to the ceiling fixture 130.

[0033] The mounting portion 130a is formed in a flat plate shape so as to be in surface contact with the ceiling CE, and insertion holes 130c and 130d are formed in the front-rear direction. As shown in FIGS. 3 and 4, fixing screws 132 for screwing the mounting portion 130a to the ceiling CE are inserted through the insertion holes 130c and 130d.

[0034] Also, as shown in FIG. 5, the wire connecting piece 130b is formed to project downward in a substantially L shape from the front end of the mounting portion 130a, and a screw hole 130e is formed therein. As shown in FIGS. 3 and 4, a wire connecting screw 131 with a washer, to which the other end of the aforementioned wire 120 is connected, is screwed into the screw hole 130e from below.

[0035] The configuration of the support device 100 has been described above. Hereinafter, the mounting procedure of the roller screen 10 to the ceiling CE will be described with reference to FIG. 6. FIG. 6 is a diagram for explaining the mounting procedure of the roller screen 10 to the ceiling CE, and shows procedures 1 to 4 in the order of (a) to (d).

[0036] Procedure 1: As shown in FIG. 6(a), the ceiling mounting tool 130 is mounted at a position near the end of the set frame 14 at a predetermined distance from the bracket 12 mounted on the ceiling CE. Procedure 2: As shown in FIG. 6(b), the set frame mounting tool 110 is mounted on the set frame 14, and one end of the wire 120 is fastened to the set frame mounting tool 110 by a wire connecting screw 114. Procedure 3: As shown in FIG. 6(c), the set frame 14 is mounted on the bracket 12. Procedure 4: As shown in FIG. 6(d), the other end of the wire 120 is fastened to the ceiling mounting tool 130 with a wire connecting screw 131. In this way, with the set frame 14 supported by the bracket 12 mounted on the ceiling CE, the roller screen 10 and the ceiling CE are connected by the support device 100 including the set frame mounting tool 110, the wire 120, and the ceiling mounting tool 130.

[0037] The above described an example of the procedure for attaching the roller screen 10 to the ceiling CE. Note that the procedure for attaching the roller screen 10 to the ceiling CE is not limited to the above-described procedure. For example, before attaching the set frame 14 to the bracket 12, the wire 120 can be fastened to both the ceiling fixture 130 and the set frame fixture 110, and then the set frame 14 can be attached to the bracket 12.

[0038] Hereinafter, the state in which the roller screen 10 is supported by the support device 100 will be described with reference to FIG. 7. FIG. 7 is a view showing a state in which the support device 100 maintains the connection between the set frame 14 and the ceiling CE in a non-fixed state where the set frame 14 is not fixed to the ceiling CE by the bracket 12. As shown in FIG. 7, since the set frame 14 can be supported so as to be suspended by the support device 100, even if a poor attachment of the set frame 14 to the bracket 12 or the like occurs, it is possible to prevent the roller screen 10 from falling.

[0039] (Effect of the First Embodiment) As described above, according to the present embodiment, even in a non-fixed state where the set frame 14 is not fixed to the ceiling CE by the bracket 12, the support device 100 can maintain the connection between the roller screen 10 and the ceiling CE. Therefore, the safety can be further improved.

[0040] In addition, since the wire 120 is connected to the ceiling CE via the ceiling fixture 130 attached to the ceiling CE, it can be connected at an arbitrary position. Therefore, the workability is improved.

[0041] In addition, since the set frame fixture 110 and the ceiling CE can be connected using the wire 120, it is inexpensive and excellent in workability during assembly. It is also advantageous in that there is no need to increase the size of the device.

[0042] In addition, since the attachment fixture 110 for the set frame is attached so as to surround the periphery of the set frame 14, the roll screen 10 can be more reliably supported by the attachment fixture 110 for the set frame.

[0043] Moreover, since the attachment fixture 110 for the set frame can be retrofitted to the set frame 14, the support device 100 can be made an optional component that can be attached as needed.

[0044] Also, since the first plate member 111 and the second plate member 112 that constitute the attachment fixture 110 for the set frame can be made of the same component, it is also advantageous in terms of parts management.

[0045] In addition, one end of the wire 120 is connected to the short-side connection piece 111b and the long-side connection piece 112c that protrude from the rear side in the front-rear direction of the attachment fixture 110 for the set frame, and the wire 120 is connected to the attachment fixture 110 for the set frame at a position where it does not interfere with the screen 18. Therefore, it is possible to prevent the screen 18 from being damaged due to interference between the wire 120 and the screen 18, or to prevent friction noise from occurring due to interference between the wire 120 and the attachment fixture 110 for the set frame during lifting and lowering.

[0046] Also, since the connection between the attachment fixture 110 for the set frame and the wire 120 is at the upper rear side of the attachment fixture 110 for the set frame, contact with the raised weight bar 20 is prevented.

[0047] In addition, since the short-side connection piece 111b and the long-side connection piece 112c of the attachment fixture 110 for the set frame are inclined obliquely downward, a gap that widens toward the rear end is formed between them and the ceiling CE. Therefore, the work of attaching the wire connection screw 114 becomes easier.

[0048] In addition, since the attachment fixture 110 for the set frame and the attachment fixture 130 for the ceiling can be connected in advance by the wire 120, and the set frame 14 can be attached to the bracket 12, it also prevents the roll screen 10 from falling when attaching it to the bracket 12.

[0049] In addition, since side brackets 15 that rotatably support the winding pipe 16 are provided at both ends of the set frame 14, even if the set frame 14 may laterally shift with respect to the attachment fixture 110 for the set frame, further lateral shift is restricted by the side brackets 15. Therefore, it is possible to prevent the attachment fixture 110 for the set frame from coming off from the end of the set frame 15.

[0050] (Second Embodiment) Next, the configuration of the support device 200 according to the second embodiment will be described with reference to FIG. 8. FIG. 8 is a diagram showing the support device 200 of the second embodiment, where (a) is a perspective view and (b) is a side view. In this embodiment, the configuration of the support device 200 is different from that of the support device 100 of the first embodiment. In this embodiment, the description will focus on the differences from the first embodiment described above. For components having substantially the same functional configuration, the same reference numerals will be given and redundant description will be omitted.

[0051] As shown in FIG. 8, the support device 200 has an attachment fixture 210 for the set frame formed of a binding band. The attachment fixture 210 for the set frame is attached so as to surround the set frame 14. Note that the attachment fixture 210 for the set frame is preferably formed of a metal binding band, but may be formed of a binding band such as resin as long as sufficient strength can be ensured. The wire 220 has a tip that is folded back to form a loop 220a, and at the upper part of the set frame 14, the attachment fixture 210 for the set frame is inserted through the loop 220a and connected. Since the upper part of the set frame 14 is open, it is easy to insert the attachment fixture 210 for the set frame through the loop 220a.

[0052] (Effects of the Second Embodiment) As described above, according to the present embodiment, since the attachment fixture 210 for the set frame is composed of a binding band, it is easy to attach and is inexpensive.

[0053] (Third Embodiment) Next, the configuration of the support device 300 according to the third embodiment will be described with reference to FIG. 9. FIG. 9 is a diagram showing the support device 300 of the third embodiment, (a) is a perspective view, and (b) is a side view. In the present embodiment, the configuration of the support device 300 is different from that of the support device 100 of the first embodiment. In the present embodiment, the description will be centered on the points different from the first embodiment above. For components having substantially the same functional configuration, the same reference numerals will be given to omit redundant description.

[0054] As shown in FIG. 9, the support device 300 is such that the attachment fixture 310 for the set frame is attached only to the upper end portion of the set frame 14. The attachment fixture 310 for the set frame has its front and rear sides bent inward to form locking pieces 310a. Further, on the rear side of the attachment fixture 310 for the set frame, a connecting piece 310b for connecting one end of a wire 120 (not shown) by a wire connecting screw 314 protrudes obliquely upward toward the rear. Therefore, similar to the attachment fixture 110 for the set frame of the first embodiment, the raised weight bar 20 does not interfere with the connecting piece 310b. The attachment fixture 310 for the set frame is attached with the locking piece 310a locked to the flange portion 14a formed at the upper end of the set frame 14.

[0055] (Effect of the Third Embodiment) As described above, according to the present embodiment, since the attachment fixture 310 for the set frame is attached only to the upper end portion of the set frame 14, the attachment fixture 310 for the set frame can be attached with good design.

[0056] (Fourth Embodiment) Next, the configuration of the support device 400 according to the fourth embodiment will be described with reference to FIG. 10. FIG. 10 is a diagram showing the support device 400 of the fourth embodiment, where (a) is a perspective view and (b) is a side view. In this embodiment, the configuration of the support device 400 is different from that of the support device 300 of the third embodiment. In this embodiment, the description will focus on the differences from the first embodiment. For components having substantially the same functional configuration, the same reference numerals will be given to omit redundant description.

[0057] As shown in FIG. 10, the support device 400 is configured such that the set frame fixture 410 is attached only to the upper end portion of the set frame 14, similar to the set frame fixture 310 of the third embodiment. The set frame fixture 410 is divided into a front plate member 411 and a rear plate member 412, and is configured to be retrofitted to the set frame 14 without removing the side bracket 15. The front plate member 411 and the rear plate member 412 are connected by two screws 413. Locking pieces 411a and 412a for locking to the flange portion 14a of the set frame 14 are formed on the front plate member 411 and the rear plate member 412. Further, a connecting piece 410b is formed on the rear plate member 412. A wire 120 (not shown) is connected to the connecting piece 410b by a wire connecting screw 414.

[0058] The attachment of the set frame fixture 410 to the set frame 14 is the same as that of the set frame fixture 310 of the third embodiment. Note that the set frame fixture 410 can also be configured to be able to change the size in the front-rear direction by increasing the number of screw holes for attaching the screws 413 and allowing the attachment position of the screws 413 to be selected. Also, in order to be able to change the size in the front-rear direction, the shape of the screw holes can be made into long holes without increasing the number of screw holes. In this case, in order to suppress the relative movement of the front plate member 411 and the rear plate member 412 after attachment, it is preferable to form irregularities or the like on the contact surfaces of both.

[0059] (Effect of the Fourth Embodiment) As described above, according to this embodiment, since the fixture 410 for the set frame is configured to be divided into two parts in the front-rear direction, the fixture 410 for the set frame can be retrofitted to the set frame 14 without removing the side bracket 15. In addition, since the size of the fixture 410 for the set frame in the front-rear direction can also be configured to be changeable, it can be made to correspond regardless of the width of the set frame 14 in the front-rear direction.

[0060] (Fifth Embodiment) Next, the configuration of the support device 500 according to the fifth embodiment will be described with reference to FIG. 11. FIG. 11 is a diagram showing the support device 500 of the fifth embodiment, where (a) is a perspective view and (b) is a side view. In this embodiment, the configuration of the support device 500 is different from that of the support device 300 of the third embodiment. In this embodiment, the description will be centered on the points different from the first embodiment above. For components having substantially the same functional configuration, the same reference numerals will be given and duplicate description will be omitted.

[0061] As shown in FIG. 11, the support device 500 is such that a fixture 510 for the set frame is attached to, for example, the upper end of the head rail 30 of a vertical blind. The basic configuration of the fixture 510 for the set frame is the same as that of the fixture 310 for the set frame of the third embodiment, and a locking piece 510a locked to the flange portion 30a of the head rail 30 and a connecting piece 510b are formed.

[0062] (Effect of the Fifth Embodiment) As described above, according to this embodiment, the fixture 510 for the set frame can be attached to the head rail 30 with good design. Also, in a blind in which a shielding material moves along the longitudinal direction of the head rail 30, such as a vertical blind, it is particularly advantageous because the fixture 510 for the set frame does not interfere with the movement of the shielding material.

[0063] (Sixth Embodiment) Next, the configuration of the support device 600 according to the sixth embodiment will be described with reference to FIG. 12. FIG. 12 is a diagram showing the support device 600 of the sixth embodiment, where (a) is a side sectional view and (b) is a front view. In this embodiment, the configuration of the support device 600 is different from that of the support device 100 of the first embodiment. In this embodiment, the description will focus on the differences from the above first embodiment. For components having substantially the same functional configuration, the same reference numerals will be given to omit duplicate explanations.

[0064] As shown in FIG. 12, the support device 600 is not provided with the wire 120 and the ceiling fixture 130 as in the first embodiment, and is composed of only the set frame fixture 610 and the fixing screw 620 (connecting member). The set frame fixture 610 is configured in a substantially concave shape and can accommodate the bracket 12 and the set frame 14 supported by the bracket 12 inside. The rear corner of the set frame fixture 610 has a tapered surface 610a to prevent the weight bar from interfering with the set frame fixture 610 when the screen is wound up. The set frame fixture 610 has attachment pieces 610b protruding in the front-rear direction from the upper edge. The attachment pieces 610b are fixed to the ceiling CE with the fixing screws 620.

[0065] The set frame fixture 610 accommodates the bracket 12 and the set frame 14 supported by the bracket 12 inside, and is attached by connecting the attachment pieces 610b to the ceiling CE with the fixing screws 620. In this way, since the set frame fixture 610 is provided so as to surround the bracket 12 and the set frame 14 from the front, rear, and below, the bracket 12 can be hidden.

[0066] (Effect of the Sixth Embodiment) As described above, according to this embodiment, since the set frame fixture 610 can cover and conceal the parts of the bracket 12 and the set frame 14 locked to the bracket 12, the designability can be improved.

[0067] In addition, since the support device 600 is composed of only the set frame fixture 610 and the fixing screw 620, its structure is simple and it can be configured with a small number of components.

[0068] Also, since the set frame fixture 610 is only connected to the ceiling CE with the fixing screw 620, the workability is also good.

[0069] 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.

[0070] For example, in the above first embodiment, the wire 120 is connected to the rear side in the front-rear direction of the set frame fixture 110, but the present invention is not limited to this example. The wire 120 may be connected to either one of the front and rear directions of the set frame fixture 110. The same applies to other embodiments.

[0071] Also, in the above first embodiment, the wire 120 is connected to the ceiling CE by the ceiling fixture 130, but the present invention is not limited to this example. It can be arbitrarily designed as long as the wire 120 can be connected to the ceiling CE. For example, the wire 120 may be directly connected to the ceiling CE.

[0072] Also, in the above first embodiment, the fixing surface for attaching the ceiling fixture 130 is the ceiling CE, but the present invention is not limited to this example. It may be attached to a window frame or a wall surface as long as it is a fixing surface. The same applies to other embodiments.

[0073] In the first embodiment, the support devices 100 are provided at both ends of the set frame 14. However, the present invention is not limited to this example. The number of support devices can be arbitrarily designed. For example, the number of support devices can be determined according to the length of the set frame. When the set frame is short, one support device may be sufficient. Also, when the set frame is long, three or more support devices can be provided.
