Description

[Technical Field]

[0001] The present invention relates to a covering device for blinds. [Background technology]

[0002] A conventional blind cover device is disclosed in Japanese Patent Application Laid-Open No. 2013-136900 (Patent Document 1). The blind cover device disclosed in this document includes an attachment main body that is detachably attached to a set frame, and a cover material that is swingably supported by the attachment main body and has a width length that corresponds to the length of the winding pipe. The cover material is characterized in that a portion of the cover material contacts the winding pipe or the screen wound around the winding pipe, and covers at least a portion of the winding pipe in the vertical direction when viewed from the front.

[0003] According to this, the cover material can be attached and detached to the set frame via the mounting body, so it can be attached to the set frame of an existing product, and by attaching the cover material, the cover material covers the gap between the set frame and the winding pipe, preventing light leakage from this gap.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-136900 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the blind cover device disclosed in Patent Document 1, although the cover material can swing relative to the mounting body, the two are integrated into one structure. Therefore, after the mounting body is attached to the set frame, even if the position of the cover material is shifted in the longitudinal direction relative to the winding pipe, the longitudinal position of the cover material cannot be adjusted relative to the winding pipe unless the mounting body is removed from the set frame, which poses a problem.

[0006] The present invention has been made in consideration of these problems, and its object is to provide a blind cover device that makes it easy to align the cover material with respect to the longitudinal direction of the support member. [Means for solving the problem]

[0007] In order to solve the above problems, according to the present invention, there is provided a blind cover device that can be attached to a blind having a support member attached to a fixed surface via a bracket and a shielding material suspended from the support member in an openable and closable manner, and that can cover at least a portion of the support member and the shielding material from the front, the blind cover device comprising: a cover material arranged on the front side of the support member; and a cover material bracket fixed to the support member, the cover material having a cover portion that covers at least a portion of the support member, and an attachment portion that protrudes from the back surface of the cover portion toward the support member and is formed along the longitudinal direction of the cover material, the cover material bracket having a locking portion that locks the attachment portion, and the attachment portion and the locking portion are temporarily fixed to prevent the cover material from falling off the cover material bracket while allowing it to move in the longitudinal direction.

[0008] According to this configuration, the cover material can be supported by the cover material bracket in a temporarily fixed state, which makes it easier to adjust the position of the cover material in the longitudinal direction. Therefore, it is easy to align the cover material with respect to the longitudinal direction of the support member.

[0009] The present invention has various applications. The following application examples can be combined as appropriate. For example, the mounting portion may include a cover-side temporary fastening portion formed in a concave or convex shape along the longitudinal direction, and the locking portion may include a bracket-side temporary fastening portion formed in a convex or concave shape. With this configuration, the temporary fastening is performed by engaging the concave and convex portions, allowing the cover material to be stably positioned in the longitudinal direction while restricting movement in the front-to-rear direction.

[0010] The locking portion may be bifurcated at the end of the cover material bracket, and the mounting portion may be inserted between the bifurcated locking portions to temporarily secure the mounting portion. With this configuration, the mounting portion can be temporarily secured by simply inserting it into the bifurcated locking portion, so that the cover material can be easily supported by multiple cover material brackets.

[0011] Furthermore, the locking portion and the mounting portion may be fixed by a fixing means capable of restricting longitudinal movement of the cover material in a temporarily fixed state. According to this configuration, by fixing the cover material and the cover material bracket by the fixing means after longitudinal alignment, the cover material and the cover material bracket can be integrated, and the longitudinal position of the cover material can be determined.

[0012] Furthermore, the front-rear position of the attachment portion relative to the locking portion may be adjustable in stages. With this configuration, the front-rear position of the cover material can be adjusted in accordance with changes in the size and winding diameter of the support member. [Effects of the Invention]

[0013] The blind cover device of the present invention facilitates alignment of the cover material with respect to the longitudinal direction of the support member. Other advantages of the present invention will be described in the detailed description of the invention below. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and drawings, components having substantially the same functional configurations are designated by the same reference numerals, and redundant explanations will be omitted.

[0016] (First embodiment) A blind covering device 100 according to a first embodiment will be described with reference to Figures 1 and 2. Figure 1 shows the overall configuration of a roller blind 10 using the blind covering device 100 of the first embodiment, where (a) is a front view and (b) is a front view with the cover material 110 removed. Figure 2 shows the roller blind 10 using the blind covering device 100, where (a) is a side view and (b) is a plan view.

[0017] First, the configuration of a roller blind 10 in which the blind cover device 100 is used will be described with reference to FIGS. 1 and 2. In this embodiment, a roller blind 10 will be described as an example, but the present invention is not limited to this and can be applied to any type of blind, such as a horizontal blind, a vertical blind, a pleated blind, or a Roman shade. As shown in FIGS. 1 and 2, the roller blind 10 has a set frame 12 (support member) attached to a fixed surface FS via a blind mounting bracket 11 (bracket). Side plates 13 (support members) are provided on both ends of the set frame 12, and both ends of a winding pipe 14 are rotatably supported on the side plates 13. The upper end of a screen 15 (shielding material) is hung from the winding pipe 14 so as to be able to open and close, and a weight bar 16 is provided at the lower end of the screen 15.

[0018] The configuration of the roller blind 10 has been described above. Below, the configuration of the blind covering device 100, which is a characteristic configuration of the present invention, will be described with reference to Figures 1 and 2. As shown in Figures 1 and 2, the blind covering device 100 is capable of covering at least a portion of the set frame 12, side plate 13, and screen 15 from the front, and is composed of a covering material 110 arranged on the front side of the set frame 12, and a covering material bracket 120 fixed to the set frame 12. Below, each part of the blind covering device 100 will be described in detail.

[0019] (Cover material 110) 1 and 2, the cover material 110 is configured to include a cover portion 112 that covers at least a portion of the screen 15 wound around the set frame 12, the side plate 13, and the winding pipe 14, and an attachment piece 114 that protrudes from the back surface of the cover portion 112 toward the set frame 12 and is formed along the longitudinal direction of the cover material 110. The cover portion 112 is configured in the shape of a long plate, and is arranged to extend between the two side plates 13 in the left-right direction and to extend from a position close to the fixing surface FS to below the side plate 13 in the up-down direction.

[0020] The mounting piece 114 (mounting portion) is used to mount the cover material 110 to the covering material bracket 120. As shown in FIG. 2, the mounting piece 114 has a retaining portion 116 formed in an inverted concave shape at its tip. The retaining portion 116 prevents the mounting piece 114 from coming off the engaging portion 122, which will be described later. A screw 130 (fixing means) is inserted into the retaining portion 116, and the tip of the screw 130 abuts against the upper inside surface of the retaining portion 116, thereby fixing the mounting piece 114 to the covering material bracket 120. A cover-side temporary fastening portion 118, which is formed in a concave shape and fits into a bracket-side temporary fastening portion 124, which will be described later, is formed between the back surface of the cover portion 112 and the retaining portion 116. When the cover-side temporary fastening portion 118 is fitted into the bracket-side temporary fastening portion 124, forward movement is restricted by the retaining portion 116 abutting against the bracket-side temporary fastening portion 124, and rearward movement is restricted by the back surface of the cover portion 112 abutting against the tip of the locking portion 122. Therefore, by fitting the cover-side temporary fastening portion 118 into the bracket-side temporary fastening portion 124, movement of the cover material 110 in the longitudinal direction is permitted while movement in the longitudinal direction is restricted.

[0021] (Cover material bracket 120) The cover material brackets 120 are used to attach the cover material 110 to the set frame 12. As shown in FIG. 1, the cover material brackets 120 are provided at at least two locations in the longitudinal direction of the set frame 12, and are arranged adjacent to the inside of the blind mounting brackets 11.

[0022] The configuration of the covering material bracket 120 will be described with reference to Figure 3. Figure 3 is a partial cross-sectional side view of the covering material bracket 120. As shown in Figure 3, the covering material bracket 120 has a locking portion 122 that locks the mounting piece 114. The mounting piece 114 and the locking portion 122 are configured to be temporarily fastened in a state in which the covering material bracket 120 locks the covering material 110 and restricts movement in the front-to-rear direction, that is, in a state in which the covering material bracket 120 prevents the covering material 110 from falling off the covering material bracket 120, but allows movement of the covering material 110 in the longitudinal direction.

[0023] The covering bracket 120 also has a fixing portion 126 for fixing to the set frame 12. Front and rear locking projections 126a, 126b for locking to the set frame 12 are formed on the front and rear ends of the fixing portion 126. The covering bracket 120 is made of resin, metal, or the like, and the locking portion 122 and the fixing portion 126 are configured to be elastically deformable.

[0024] As shown in Fig. 3, the end of the locking portion 122 is bifurcated in the vertical direction. The locking portion 122 is configured so that its front-to-rear width is approximately half the width of the tip portion and the end portion on the side of the fixing portion 126. The locking portion 122 forms a bracket-side temporary fastening portion 124 whose top edge on the tip side is formed in a concave shape and whose top-to-bottom width is narrow. A tapered easy-removal portion 124a is formed at the corner of the upper rear end of the bracket-side temporary fastening portion 124, making it easy to pull out the mounting piece 114 from the locking portion 122 when removing the cover material 110 from the cover material bracket 120.

[0025] At the tip of the locking portion 122, a tapered easy-insertion portion 122a is formed such that the spacing between the two branches becomes wider as it approaches the tip, making it easier to insert the attachment piece 114 into the locking portion 122. As shown in Figure 2(a), the cover material 110 is temporarily fastened when the attachment piece 114 is inserted into the locking portion 122.

[0026] As shown in Fig. 3, a screw mounting portion 128 with a female threaded hole is formed at the bottom of the locking portion 122. A screw 130 is screwed into the screw mounting portion 128 in advance to a position that does not restrict the insertion of the mounting piece 114, and by further screwing the screw 130 all the way in, the locking portion 122 and the mounting piece 114 are fixed together, thereby restricting longitudinal movement of the cover material 110 in a temporarily fixed state. Note that in this embodiment, the locking portion 122 and the mounting piece 114 are fixed together by the screw 130, but any configuration can be used as long as it can fix the locking portion 122 and the mounting piece 114. For example, the locking portion may clamp the mounting piece to fix it.

[0027] The overall configuration of the blind cover device 100 of this embodiment has been described above. The procedure for attaching the cover material 110 will now be described with reference to Figures 4 to 9. Figures 4 to 9 are diagrams showing the procedure for attaching the cover material 110.

[0028] (1) As shown in Figure 4(a), tilt the cover material bracket 120 so that the fixing portion 126 of the cover material bracket 120 is inserted between the set frame 12 of the roller blind 10 attached to the fixing surface FS and the fixing surface FS.

[0029] (2) As shown in Fig. 4(b), the cover material bracket 120 is inserted from the front between the fixing surface FS and the set frame 12. Then, as shown by the imaginary line in Fig. 4(b) and Fig. 7(a), the fixing part 126 is inserted up to the top of the set frame 12.

[0030] (3) As shown in Figure 5(a), first, the rear locking projection 126a of the fixing part 126 is hooked onto the rear flange 12a of the set frame 12. Next, the front side of the fixing part 126 is pulled down to elastically deform the fixing part 126, and the front locking projection 126b is locked onto the front flange 12b of the set frame 12. Then, as shown by the imaginary lines in Figure 5(a) and Figure 7(b), the front and rear locking projections 126a, 126b of the fixing part 126 are locked onto the front and rear flanges 12a, 12b of the set frame 12, and the fixing part 126 is fixed.

[0031] (4) As shown in Figures 5(b), 8(a), and 9(a), the mounting piece 114 of the cover material 110 is inserted into the locking portion 122 from the front of the cover material bracket 120. At this time, the mounting piece 114 presses the easy-insertion portion 122a, causing the locking portion 122 to elastically deform and open in the vertical direction, allowing the mounting piece 114 to be inserted. At this time, the tip of the screw 130 does not restrict the insertion of the mounting piece 114. When the retaining portion 116 passes over the bracket-side temporary fastening portion 124 and is positioned in the locking portion 122, the cover-side temporary fastening portion 118 engages with the bracket-side temporary fastening portion 124, and the cover-side temporary fastening portion 118 is allowed to move left and right but is restricted from moving forward and backward by the bracket-side temporary fastening portion 124. Thus, the cover material 110 is temporarily fastened to the cover material bracket 120 so that movement in the left and right direction is permitted but movement in the front and rear direction is restricted.

[0032] (5) As shown in Figures 6(a), 8(b), and 9(b), slide the cover material 110 left and right on the cover material bracket 120 to align the cover portion 112 so that it covers the left and right side plates 13.

[0033] (6) As shown in Figure 6(b), a screw 130 is screwed into the upper inner side of the retaining portion 116 from the screw mounting portion 128 of the cover material bracket 120, and the mounting piece 114 is fixed to the locking portion 122. Thus, the cover material 110 is fixed to the cover material bracket 120.

[0034] 4 to 9 show the screen 15 wound around the winding pipe 14, it goes without saying that the cover material 110 may also be attached to the cover material bracket 120 with the screen 15 unwound from the winding pipe 14. If the rolled diameter of the roller blind 10 is large and it is difficult to screw the screws 130 into the screw mounting portions 128, the cover material 110 may be attached to the cover material bracket 120 in the above-described procedure with the screen 15 unwound from the winding pipe 14.

[0035] (Effects of the first embodiment) As described above, according to this embodiment, the cover material 110 can be supported in a temporarily fixed state on the cover material bracket 120, making it easy to adjust the position of the cover material 110 in the longitudinal direction. Therefore, it is easy to align the cover material 110 with respect to the longitudinal direction of the set frame 12.

[0036] Furthermore, by temporarily fastening the cover material 110 and the cover material bracket 120 by engaging the cover side temporary fastening portion 118 and the bracket side temporary fastening portion 124 with their concave and convex portions, the position of the cover material 110 can be adjusted in the longitudinal direction in a stable manner while restricting movement of the cover material 110 in the forward and backward directions.

[0037] Furthermore, since the attachment piece 114 can be temporarily fastened simply by inserting it into the forked locking portion 122, the cover material 110 can be easily supported by a plurality of cover material brackets 120.

[0038] Furthermore, by fixing the cover material 110 with screws 130 after aligning the cover material 110 in the longitudinal direction, the cover material 110 and the cover material bracket 120 can be integrated, and the cover material 110 can be positioned in the longitudinal direction.

[0039] (Second embodiment) Next, a blind covering device 200 according to a second embodiment will be described with reference to Figure 10. Figure 10 is a side view showing the blind covering device 200 of the second embodiment. This embodiment differs from the blind covering device 100 of the first embodiment in that the attachment position of the covering material 210 to the covering material bracket 220 can be adjusted forward and backward. This embodiment will be described mainly focusing on the differences from the first embodiment. Components having substantially the same functional configuration will be assigned the same reference numerals, and redundant explanations will be omitted.

[0040] The covering material 210 has an attachment piece 214 that is longer in the front-to-rear direction than the attachment piece 114 of the first embodiment, and is provided with two retaining portions 216-1, 216-2 in the front-to-rear direction. A front cover-side temporary fastening portion 218-1 that fits into the bracket-side temporary fastening portion 124 of the covering material bracket 220 is formed between the back surface of the cover portion 112 and the front retaining portion 216-1. In addition, a rear cover-side temporary fastening portion 218-2 that fits into the bracket-side temporary fastening portion 124 of the covering material bracket 220 is formed between the front retaining portion 216-1 and the rear retaining portion 216-2. The other configurations are the same as those of the covering material 110 of the first embodiment.

[0041] The covering material bracket 220 has a width in the front-rear direction of the locking portion 222 from the tip to the end on the fixing portion 126 side. The other configurations are the same as those of the covering material bracket 120 of the first embodiment.

[0042] The configuration of the blind cover device 200 has been described above. Next, the operation of the blind cover device 200 will be described with reference again to FIG. 10 . When used with a roller blind 10 having a small roll diameter, the mounting piece 214 is inserted up to the rear end of the locking portion 222, as shown in FIG. 10( a). In this state, the front and rear retaining portions 216-1 and 216-2 pass the bracket-side temporary fastening portion 124 and are positioned at the locking portion 222, so that the front retaining portion 216-1 and the screw mounting portion 128 are aligned. Furthermore, the front cover-side temporary fastening portion 218-1 fits into the bracket-side temporary fastening portion 124. When the front cover-side temporary fastening portion 218-1 fits into the bracket-side temporary fastening portion 124, forward movement is restricted by the front retaining portion 216-1 abutting against the bracket-side temporary fastening portion 124, and rearward movement is restricted by the rear surface of the cover portion 112 abutting against the tip of the locking portion 222. Therefore, the front cover-side temporary fastening portion 218-1 is fitted into the bracket-side temporary fastening portion 124, and is temporarily fastened to the cover material bracket 220 so that movement in the left-right direction is permitted but movement in the front-rear direction is restricted. After aligning the cover material 210, the front stopper portion 216-1 and the locking portion 222 are fixed with the screw 130 via the screw mounting portion 128, and the cover material 210 is fixed to the cover material bracket 220, as in the first embodiment.

[0043] In this way, the mounting piece 214 is inserted into the locking portion 222 up to the position where the front retaining portion 216-1 and the locking portion 222 are fixed together, so the cover portion 112 approaches the position of the roller blind 10. As a result, even with a roller blind 10 having a small roll diameter, the gap between the cover portion 112 and the screen 15 becomes smaller, improving the light blocking performance.

[0044] Next, when used with a roller blind 10 having a large roll diameter, as shown in FIG. 10(b), the rear retaining portion 216-2 is inserted past the bracket-side temporary fastening portion 124 to a position where it is positioned at the locking portion 222. At this time, the positions of the rear retaining portion 216-2 and the screw mounting portion 128 are aligned. In addition, the rear cover-side temporary fastening portion 218-2 fits into the bracket-side temporary fastening portion 124. When the rear cover-side temporary fastening portion 218-2 fits into the bracket-side temporary fastening portion 124, forward movement is restricted by the rear retaining portion 216-2 abutting against the bracket-side temporary fastening portion 124, and rearward movement is restricted by the front retaining portion 216-1 abutting against the bracket-side temporary fastening portion 124. Therefore, the rear cover-side temporary fastening portion 218-2 is fitted into the bracket-side temporary fastening portion 124, and is temporarily fastened to the cover material bracket 220 so that movement in the left-right direction is permitted but movement in the front-rear direction is restricted. After aligning the cover material 210, the rear retaining portion 216-2 and the locking portion 222 are fixed with the screw 130 via the screw mounting portion 128, and the cover material 210 is fixed to the cover material bracket 220, as in the first embodiment.

[0045] In this way, the mounting piece 214 is inserted into the locking portion 222 up to the position where the rear retaining portion 216-2 and the locking portion 222 are fixed together, so the cover portion 112 is separated from the position of the roller blind 10. As a result, even with a roller blind 10 having a large roll diameter, the cover portion 112 does not come into contact with the screen 15 and the distance between the cover portion 112 and the screen 15 can be reduced, improving the light blocking performance.

[0046] In this embodiment, the front-rear direction position of the attachment piece 214 relative to the locking portion 222 is adjusted in two stages, but it may be adjusted in three or more stages. For example, this may be achieved by increasing the number of cover-side temporary fastening portions.

[0047] (Effects of the second embodiment) As described above, according to this embodiment, the position of the cover material 110 in the front-rear direction can be adjusted in accordance with changes in the size of the side plate 13 and the roll diameter of the roller blind 10.

[0048] While the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such examples. It is clear that those skilled in the art can conceive of various modifications and alterations within the scope of the claims, and it is understood that these modifications and alterations also fall within the technical scope of the present invention.

[0049] For example, in the first embodiment described above, the mounting piece 114 includes a cover-side temporary fastening portion 118 formed in a concave or convex shape along the longitudinal direction, and the locking portion 122 includes a bracket-side temporary fastening portion 124 formed in a convex or concave shape. However, the present invention is not limited to this example. The mounting portion and the locking portion may have any configuration as long as they can temporarily fasten the cover material so as to restrict its movement in the front-to-rear direction while allowing it to move in the longitudinal direction. For example, the tips of the mounting portion and the locking portion may be formed in a roughly U-shape, and the tips may be temporarily fastened by hooking together in the front-to-rear direction. Alternatively, the mounting portion and the locking portion may be temporarily fastened in the vertical direction. For example, the mounting portion may be formed in a roughly L-shape that bends downward, and the locking portion may be formed in a concave shape, and the downwardly bent piece of the mounting portion may be inserted from above the locking portion to temporarily fasten the mounting portion.

[0050] Furthermore, in the first embodiment, the locking portion 122 is formed in a bifurcated shape at the end of the covering material bracket 120, and the mounting piece 114 is inserted into the locking portion 122 to be temporarily fastened, but the present invention is not limited to this example. The mounting piece 114 may be formed in a bifurcated shape, and the locking portion 122 of the covering material bracket 120 may be inserted into the mounting piece 114. Furthermore, the mounting portion and the locking portion may have any configuration as long as they can be temporarily fastened to prevent the covering material from falling off the covering material bracket while allowing movement in the longitudinal direction.

[0051] Furthermore, in the first embodiment, when fixing the cover material bracket 120 to the set frame 12, the rear locking projection 126a of the fixing portion 126 is hooked onto the rear flange 12a of the set frame 12, and then the front side of the fixing portion 126 is pulled down to elastically deform the fixing portion 126, and the front locking projection 126b is locked onto the front flange 12b of the set frame 12, but the present invention is not limited to this example.
