Description

[Technical Field]

[0001] The present invention relates to a blind vibration rest device and a blind vibration rest mechanism. [Background technology]

[0002] A conventional blind vibration prevention device is disclosed in Japanese Patent Application Laid-Open No. 2014-43707 (Patent Document 1). This document discloses that, of first and second vertical cords that hang down from a head box and constitute a ladder cord, a ring member is provided at each joint between the vertical cord that hangs down on the window side and multiple horizontal cords that are stretched between the first and second vertical cords, and a guide wire whose upper end is connected to a fixed surface such as the head box or ceiling by an upper fixing member and whose lower end is connected to a fixed surface such as the floor by a lower fixing member is inserted into each ring member.

[0003] This prevents the slats from shaking or swaying even when the wind blows, and also prevents the slats from bulging in the vertical center, allowing wind to be smoothly introduced into the room. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-43707 Summary of the Invention [Problem to be solved by the invention]

[0005] However, conventional blind sway prevention devices such as those disclosed in Patent Document 1 required ring members to be attached to the ladder cord in advance, and guide wires had to be passed through multiple rings, posing installation challenges.

[0006] The present invention was made in consideration of such problems, and its purpose is to provide a blind vibration prevention device and blind vibration prevention mechanism that are easy to install and allow the shielding material to be raised and lowered. [Means for solving the problem]

[0007] In order to solve the above problems, according to a first aspect of the present invention, there is provided a blind sway prevention device that attaches a head box to an upper fixed surface and regulates the swinging of a bottom rail provided at the lower end of a shielding material suspended from the head box, the blind sway prevention device comprising a pair of vertical frames arranged in front of and behind the shielding material, and at least one horizontal frame connecting the pair of vertical frames, the horizontal frame being arranged in a position that does not regulate the raising and lowering of the bottom rail, at least when the bottom rail is raised from its lowermost position to a predetermined height, and the upper ends of the pair of vertical frames are abutted against the upper fixed surface or the lower surface of the head box, and the lower ends of the pair of vertical frames are abutted against a lower fixed surface, thereby causing the pair of vertical frames to stand upright.

[0008] With this configuration, installation is easy as it only requires placing a pair of vertical frames in front and behind the shielding material, and regardless of whether the bottom rail swings forward or backward, at least one of the pair of vertical frames in the front and rear can regulate the swinging of the bottom rail.

[0009] Furthermore, with the blind sway rest device installed, the bottom rail can be raised and lowered to at least a predetermined height. Furthermore, since the vertical frames can be installed with the shielding material and bottom rail raised, the shielding material does not get in the way when installing a vertical frame that is located closer to the window than the shielding material. Furthermore, by connecting a pair of vertical frames with a horizontal frame, the front and rear vertical frames can be installed with a constant spacing, which improves the efficiency of the installation work and ensures stable swing regulation (the distance between the vertical frames and the shielding material is stable).

[0010] The present invention has various applications. The following application examples can be combined as appropriate. For example, the horizontal frame may pass between the top surface of the head box and the upper fixing surface, or between the bottom rail and the lower fixing surface. This configuration prevents the horizontal frame connecting a pair of vertical frames from restricting the lifting and lowering of the shielding material.

[0011] The shielding material may be a plurality of slats supported by ladder cords suspended from the head box, and the horizontal frame may pass between the head box and the uppermost slat. With this configuration, the horizontal frame passes between the underside of the head box and the uppermost slat, so that even if the gap between the head box and the upper fixing surface is narrow, the pair of vertical frames can be installed in a connected state.

[0012] In order to solve the above problem, according to a second aspect of the present invention, there is provided a blind vibration prevention mechanism that prevents blinds from vibrating by using a plurality of blind vibration prevention devices that regulate the swinging of a bottom rail attached to the lower end of a shielding material suspended from a head box, wherein the blind vibration prevention device comprises a pair of vertical frames arranged in front of and behind the shielding material, and at least one horizontal frame that connects the pair of vertical frames, and the horizontal frame is arranged in a position that does not regulate the raising and lowering of the bottom rail, at least when the bottom rail is raised from its lowermost position to a predetermined height, and the pair of vertical frames are arranged to stand upright by abutting the upper ends of the pair of vertical frames against an upper fixed surface and abutting the lower ends of the pair of vertical frames against a lower fixed surface, and a blind vibration prevention mechanism is provided in which the head box capable of suspending the shielding material is attached across the plurality of horizontal frames, thereby allowing the pair of vertical frames to be arranged in front of and behind the shielding material.

[0013] With this configuration, simply by attaching the blind head box across the horizontal frames of multiple blind vibration restraint devices, it is possible to simultaneously install the blinds and the blind vibration restraint devices on the blinds. Because the blinds can be attached to the blind vibration restraint devices in this way, regardless of whether the bottom rail swings forward or backward, at least one of the pair of front and rear vertical frames can restrict the swinging of the bottom rail. Furthermore, the blinds can be installed without fixing brackets to the fixed surface. This simplifies the blind installation process. Furthermore, no screw holes for fixing the brackets to the fixed surface are required.

[0014] The second aspect of the present invention can also be applied in various ways. For example, the head box may be placed on each of the horizontal frames so that it can be attached across multiple horizontal frames. This configuration allows the blind to be installed without using brackets. [Effects of the Invention]

[0015] According to the present invention, it is possible to provide a blind vibration prevention device and a blind vibration prevention mechanism that are easy to install and that allow the shielding material to be raised and lowered. Other effects of the present invention will be described in the detailed description of the invention below. [Brief explanation of the drawings]

[0017] 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.

[0018] (First embodiment) A first embodiment of the present invention will be described with reference to Figs. 1 to 5. First, the overall configuration of a blind 10 employing a vibration prevention device 100 (blind vibration prevention device) of this embodiment will be described with reference to Fig. 1. Fig. 1 is a perspective view of the blind 10 and vibration prevention device 100 according to the first embodiment. Fig. 2 is a side view of the blind 10 with the vibration prevention device 100 installed.

[0019] As shown in Figures 1 and 2, the anti-vibration device 100 is installed on the blind 10, and attaches the head box 12 to the upper fixed surface US, regulating the swinging of the bottom rail 16 installed at the lower end of the slat 14 (shielding material) suspended from the head box 12.

[0020] First, the blind 10 of this embodiment will be described. However, since the blind 10 of this embodiment is a general horizontal blind, detailed description will be omitted and only a general description will be given with reference to FIG.

[0021] 1 and 2, the head box 12 is fixed to an upper fixing surface US via a bracket 18. The head box 12 can be fixed to a window frame, ceiling, or other location where the blinds 10 can close the opening. A tilting drive mechanism (not shown) is provided within the head box 12, which is driven by operation of an operating rod 20 to tilt a ladder cord 22.

[0022] The multiple slats 14 arranged below the head box 12 are supported in an aligned state by ladder cords 22. The lower ends of the ladder cords 22 are connected to the bottom rail 16. The slats 14 and bottom rail 16 are tilted by tilting the ladder cords 22 using a tilt drive mechanism driven by the operation of an operating rod 20. The multiple slats 14 and bottom rail 16 are connected at one end to the bottom rail 16, and at the other end, they are raised by passing through the row of slats 14, passing through the head box 12, and being led out from one end of the head box 12 via a stopper (not shown), and are raised and lowered by a lifting cord 24 that is inserted through the operating rod 20 and led downward.

[0023] The overall configuration of the blinds 10 has been described above. The vibration suppression device 100, which is a characteristic feature of this embodiment, will now be described with reference to Fig. 3 in addition to Figs. 1 and 2. Fig. 3 is a schematic side cross-sectional view of the blinds 10 on which the vibration suppression device 100 is installed.

[0024] 1 to 3, the vibration prevention device 100 is composed of a pair of vertical frames 110 arranged in front of and behind the slats 14, and two upper and lower horizontal frames 120, 122 that connect the pair of vertical frames 110. The horizontal frames 120, 122 are arranged in positions that do not restrict the elevation of the bottom rail 16, at least in the range in which the bottom rail 16 rises from its lowest position to a predetermined height, and are configured so that the pair of vertical frames 110 are erected by abutting the upper ends of the pair of vertical frames 110 against an upper fixed surface US and abutting the lower ends of the pair of vertical frames 110 against a lower fixed surface BS.

[0025] (Vertical frame 110) As shown in Figures 1 to 3, a pair of vertical frames 110 are arranged in front of and behind the slat 14. The pair of vertical frames 110 are configured identically. The vertical frames 110 are configured by connecting two long, rod-shaped members in an extendable manner, and a length adjustment unit 112 is provided at the connecting portion to switch between connection and release of the connection. In addition, disk-shaped abutment units 114 with a larger diameter than the rod-shaped members are provided at the upper and lower ends of the vertical frames 110. The abutment units 114 at the upper ends of the pair of vertical frames 110 are abutted against the upper fixing surface US, and the abutment units 114 at the lower ends of the pair of vertical frames 110 are abutted against the lower fixing surface BS, so that the pair of vertical frames 110 are configured to stand upright.

[0026] (Horizontal frame 120, 122) The horizontal frames 120, 122 connect a pair of vertical frames 110 to each other. As shown in Figures 1 to 3, the two upper and lower horizontal frames 120, 122 are longer than the front-to-back width of the blind 10, and both ends are connected to each of the pair of vertical frames 110. The horizontal frames 120, 122 may be fixedly connected to the vertical frames or may be detachably connected. The horizontal frames 120, 122 allow the pair of vertical frames 110 to maintain equal spacing along their entire length. The upper horizontal frame 120 is positioned between the head box 12 and the uppermost slat 14 so as not to affect the rotation of the slat 14. The lower horizontal frame 122 is positioned between the bottom rail 16 at its lowest height and the lower fixed surface BS. Therefore, the horizontal frames 120, 122 do not interfere with the raising and lowering of the slats 14 and bottom rail 16, as shown in Figure 2.

[0027] The above has described the configuration of the anti-vibration device 100. Below, the procedure for installing the anti-vibration device 100 will be described with reference to Figures 4 and 5. Figures 4 and 5 are diagrams showing the procedure for installing the anti-vibration device 100.

[0028] Step 1: As shown in FIG. 4(a), the slats 14 and bottom rail 16 of the blind 10 attached to the upper fixing surface US are raised to a position where the second-highest slats 14 cannot be folded up.

[0029] Step 2: As shown in Figure 4(b), from one end of the blinds 10, pass the upper horizontal frame 120 of the anti-vibration device 100 between the head box 12 and the topmost slat 14. At this time, pass the anti-vibration device 100 to the desired position while keeping it tilted at an angle.

[0030] Step 3: As shown in Figure 4(c), the anti-vibration device 100 is set up on the lower fixed surface BS, and the length of the vertical frame 110 is adjusted using the length adjustment part 112, and the abutment part 114 is brought into abutment with the upper fixed surface US and the lower fixed surface BS. This completes the installation of the anti-vibration device 100 on one end of the blind 10.

[0031] Step 4: As shown in Figure 5(a), while shifting the operating rod 20 to the side of the slats 14, pass the upper horizontal frame 120 of the anti-vibration device 100 from the other end of the blind 10 between the head box 12 and the topmost slat 14. At this time, pass the anti-vibration device 100 to the desired position while keeping it tilted at an angle.

[0032] Step 5: As shown in Figure 5(b), the anti-vibration device 100 is set up on the lower fixed surface BS, and the length of the vertical frame 110 is adjusted using the length adjustment part 112, and the abutment part 114 is brought into abutment with the upper fixed surface US and the lower fixed surface BS. This completes the installation of the anti-vibration device 100 on the other end of the blind 10.

[0033] Step 6: As shown in Fig. 5(c), lower the slats 14 and the bottom rail 16. In this way, the slats 14 and the bottom rail 16 can be raised and lowered even with the anti-vibration device 100 installed.

[0034] (Effects of the first embodiment) As described above, according to this embodiment, installation is easy because it only requires placing a pair of vertical frames 110 in front of and behind the slat 14, and regardless of whether the bottom rail 16 swings forward or backward, at least one of the pair of front and rear vertical frames 110 can regulate the swinging of the bottom rail 16.

[0035] Furthermore, with the anti-vibration device 100 installed, the bottom rail 16 can be raised and lowered to at least a predetermined height.

[0036] Furthermore, when installing the vertical frame 110, the work can be performed with the slats 14 and bottom rail 16 raised, so the slats 14 do not get in the way when installing the vertical frame 110 that is located closer to the window than the slats 14.

[0037] Furthermore, by connecting a pair of vertical frames 110 with upper and lower horizontal frames 120, 122, the front and rear vertical frames 110 can be installed with a constant distance between them, which improves the efficiency of the installation work and stabilizes the distance between the pair of vertical frames 110 and the slats 14, allowing for stable rocking regulation.

[0038] Furthermore, since the lower horizontal frame 122 passes between the bottom rail 16 and the lower fixed surface BS, the lower horizontal frame 122 connecting the pair of vertical frames 110 can be prevented from restricting the raising and lowering of the slats 14.

[0039] Furthermore, since the upper horizontal frame 120 passes between the underside of the head box 12 and the topmost slat 14, even if the gap between the head box 12 and the upper fixing surface US is narrow, the pair of vertical frames 110 can be installed in a connected state.

[0040] (Second embodiment) A vibration prevention device 200 according to a second embodiment will be described with reference to Fig. 6. Fig. 6 is a schematic side cross-sectional view of the vibration prevention device 200 and blinds 10 according to the second embodiment. This embodiment differs from the first embodiment in the configuration of the upper horizontal frame 220, and the following description will focus on the differences from the first embodiment. Components having substantially the same functional configuration will be assigned the same reference numerals, and redundant description will be omitted.

[0041] The anti-vibration device 200 has a modified configuration of the upper horizontal frame 120 in the anti-vibration device 100 of the first embodiment. That is, as shown in Fig. 6, the upper horizontal frame 220 is configured to pass between the top surface of the head box 12 and the upper fixed surface US. The upper horizontal frame 220 is attached so as to fit into the upper end of the vertical frame 110. The lower horizontal frame 122, like the lower horizontal frame 122 of the first embodiment, is configured to pass between the bottom rail 16 and the lower fixed surface BS.

[0042] (Effects of the second embodiment) As described above, according to this embodiment, the upper horizontal frame 220 passes between the upper surface of the head box 12 and the upper fixed surface US, thereby preventing the horizontal frame 220 connecting a pair of vertical frames 110 from restricting the raising and lowering of the slats 14.

[0043] (Third embodiment) A vibration prevention device 300 according to a third embodiment will be described with reference to Fig. 7. Fig. 7 is a schematic side cross-sectional view of the vibration prevention device 300 and blinds 10 according to the third embodiment. This embodiment omits the lower horizontal frame 122 of the second embodiment, and other configurations are the same as those of the second embodiment. This embodiment will be described mainly focusing on the differences from the second embodiment. Components having substantially the same functional configuration will be assigned the same reference numerals, and redundant explanations will be omitted.

[0044] The anti-vibration device 300 has a configuration in which the lower horizontal frame 122 in the anti-vibration device 200 of the second embodiment is omitted. In other words, as shown in Fig. 7, the anti-vibration device 300 has an upper horizontal frame 220 similar to that of the second embodiment provided above the pair of vertical frames 110, but does not have a lower horizontal frame provided below the pair of vertical frames 110.

[0045] (Effects of the third embodiment) As described above, according to this embodiment, there is no lower horizontal frame below the pair of vertical frames 110, and therefore the present invention can be applied to blinds with improved shading properties, for example, by lowering the bottom rail 16 to a position where it contacts the lower fixed surface BS, or by placing a shading member between the bottom rail 16 and the lower fixed surface BS.

[0046] (Fourth embodiment) A vibration prevention device 400 according to the fourth embodiment will be described with reference to Fig. 8. Fig. 8 is a schematic side cross-sectional view of the vibration prevention device 400 and blinds 10 according to the fourth embodiment. This embodiment omits the upper horizontal frame 120 of the first embodiment, and other configurations are the same as those of the first embodiment. 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 to avoid redundant description.

[0047] The anti-vibration device 400 has a configuration in which the upper horizontal frame 120 in the anti-vibration device 100 of the first embodiment is omitted. In other words, as shown in Fig. 8, the anti-vibration device 400 has a lower horizontal frame 122 provided only below the pair of vertical frames 110, but no upper horizontal frame provided above the pair of vertical frames 110.

[0048] (Effects of the fourth embodiment) As described above, according to this embodiment, there is no upper horizontal frame above the pair of vertical frames 110, so that the present invention can be applied to blinds that do not have a gap above or below the head box 12 for passing a horizontal frame through.

[0049] (Fifth embodiment) A vibration suppression device 500 according to a fifth embodiment will be described with reference to Fig. 9. Fig. 9 is a schematic side cross-sectional view of the vibration suppression device 500 and blinds 50 according to the fifth embodiment. This embodiment differs from the first embodiment in that a pair of vertical frames 110 are abutted against the underside of the head box 52, but other configurations are the same as those of the first embodiment. 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.

[0050] As shown in Figure 9, the anti-vibration device 500 has a configuration similar to that of the anti-vibration device 100 of the first embodiment, but the upper ends of the pair of vertical frames 110 abut against the lower surface of the head box 52 rather than the upper fixed surface US.

[0051] In this embodiment, the head box 52 of the blind 50 is configured to be larger in front-to-rear width than the slats 14, compared to the head box 12 of the first embodiment. In addition, the bracket 58 is configured to cover and support the outer periphery of the head box 52.

[0052] (Effects of the fifth embodiment) As described above, according to this embodiment, the upper ends of the pair of vertical frames 110 only need to be brought into contact with the lower surface of the head box 52, making installation easy.

[0053] (Sixth embodiment) A vibration suppression device 600 according to a sixth embodiment will be described with reference to Figs. 10 and 11. Figs. 10 and 11 are schematic side cross-sectional views of the vibration suppression device 600 and blinds 60 according to the sixth embodiment. This embodiment differs from the first embodiment in that a head box 52 is attached to the upper horizontal frame 620, but other configurations are similar to those of the first embodiment. 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.

[0054] 10 and 11, the anti-vibration device 600 has a head box 62 attached across two upper horizontal frames 620, allowing a pair of vertical frames 110 to be positioned in front of and behind the slats 14, and supporting the blinds 60. Similar to the anti-vibration device 100 of the first embodiment, the anti-vibration device 600 is erected by abutting the abutment portions 114 of the pair of vertical frames 110 against the upper fixing surface US and the lower fixing surface BS.

[0055] As shown in Fig. 10, the anti-vibration device 600 has an upper horizontal frame 620 whose upper surface is formed to conform to the shape of the bottom surface of the head box 62. That is, grooves 620a are formed in two locations in the front-to-rear direction of the upper horizontal frame 620, into which protrusions 62a protruding downward from the front and rear ends of the head box 62 fit. In addition, the upper horizontal frame 620 has trapezoidal raised protrusions 620b formed between the front and rear grooves 620a, and the bottom surface 62b of the head box 62 rests on the raised protrusions 620b. This allows the blinds 60 to be installed without using brackets.

[0056] When assembling the blinds 60 to the anti-vibration devices 600, as shown in Fig. 11, two anti-vibration devices 600 are erected between the upper and lower fixed surfaces at an interval shorter than the length of both left and right ends of the head box 62 of the blinds 60, and the head boxes 62 are attached to the upper horizontal frames 620 of each. Thus, the blinds 60 are supported by the two anti-vibration devices 600, and a pair of vertical frames 110 are positioned in front of and behind the slats 14. In this embodiment, the two anti-vibration devices 600 constitute a blind anti-vibration mechanism.

[0057] (Effects of the sixth embodiment) As described above, according to this embodiment, simply by attaching the head box 62 of the blind 60 across the upper horizontal frames 620 of multiple anti-vibration devices 600, the blind 60 can be installed and the anti-vibration devices 600 can be installed on the blind 60 simultaneously.

[0058] Furthermore, since the blinds 60 can be attached to the anti-vibration device 600, regardless of whether the bottom rail 16 swings forward or backward, at least one of the pair of front and rear vertical frames 110 can regulate the swinging of the bottom rail 16.

[0059] Furthermore, the blinds 60 can be installed without fixing brackets to the upper fixing surface US, which simplifies the installation work of the blinds 60. Furthermore, no screw holes for fixing brackets to the upper fixing surface US are formed.

[0060] (Seventh embodiment) A vibration suppression device 700 according to the seventh embodiment will be described with reference to Fig. 12. Fig. 12 is a schematic side cross-sectional view of the vibration suppression device 700 and blinds 70 according to the seventh embodiment. This embodiment differs from the third embodiment in the configuration in which the brackets 78 are attached to the upper horizontal frame 220, but other configurations are the same as those of the third embodiment. This embodiment will be described mainly focusing on the differences from the third embodiment. Components having substantially the same functional configuration will be assigned the same reference numerals, and redundant explanations will be omitted.

[0061] As shown in Figure 12, the anti-vibration device 700 has a configuration similar to that of the anti-vibration device 300 of the third embodiment, and is erected by the upper horizontal frame 220 abutting against the upper fixed surface US and the abutment portions 114 of a pair of vertical frames 110 abutting against the lower fixed surface BS.

[0062] The blinds 70 are typical pleated screens that are configured with a head box 72, a screen 74 (shielding material), a bottom rail 76, and brackets 78, and therefore detailed description thereof will be omitted.

[0063] Brackets 78 of the blinds 70 are attached to the horizontal frames 220 at the top of the multiple anti-vibration devices 700, respectively, and the blinds 70 are supported by the multiple anti-vibration devices 700. Furthermore, a pair of vertical frames 110 of the multiple anti-vibration devices 700 are arranged in front of and behind the screen 74 to regulate the swinging of the screen 74. The positions and number of anti-vibration devices 700 can be designed as desired, but, as with the sixth embodiment, it is preferable to arrange them near both ends of the blinds 70.

[0064] (Effects of the Seventh Embodiment) As described above, according to this embodiment, the blinds 70 are installed by attaching brackets 78 to the upper horizontal frames 220 of multiple anti-vibration devices 700, respectively, so that the installation of the blinds 70 and the anti-vibration devices 700 on the blinds 70 are performed simultaneously.

[0065] Furthermore, no screw holes for fixing the brackets are formed in the upper fixing surface US.

[0066] 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.

[0067] For example, in the first embodiment, two anti-vibration devices 100 are used, but the present invention is not limited to this example. The number of anti-vibration devices and their installation positions can be designed as desired. The same applies to the other embodiments.

[0068] In addition, in the sixth embodiment, the blind vibration prevention mechanism is configured using two vibration prevention devices 600, but the present invention is not limited to this example. The number of vibration prevention devices and their installation positions can be designed as desired. The same applies to the other embodiments. [Explanation of symbols]
