Description

[Technical Field]

[0001] The present invention relates to vertical blinds. [Background technology]

[0002] As a conventional typical vertical blind, Patent Document 1 below discloses a vertical blind in which a carrier from which louvers can be hung has a hanging member formed with multiple support parts each and rotatably connected to an axis, and the multiple support parts support multiple louvers at different angles on both sides of the axis.

[0003] With this, the support part of the hanging member supports multiple louvers at different angles on both sides of the carrier's axis, resulting in multiple louvers being arranged on both sides of the axis, and the amount of protrusion of the head rail in the forward and backward directions when the louvers rotate can be made uniform on both the inside and outside of the room. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2021-92103 Summary of the Invention [Problem to be solved by the invention]

[0005] However, even in the technology described in Patent Document 1, there is still room for improvement in terms of the amount of protrusion of the louvers from inside to outside the room.

[0006] In view of the above circumstances, an object of the present invention is to provide a vertical blind that can reduce the amount of protrusion of the louvers at least on the indoor or outdoor side. [Means for solving the problem]

[0007] To achieve the above object, a vertical blind according to one aspect of the present invention includes a plurality of carriers and first and second louvers. Each carrier has a shaft and is movable longitudinally within a head rail. The first and second louvers are suspended from the plurality of carriers via the shafts. Each carrier has a suspension member rotatably connected to the shaft, the suspension member including a first suspension portion capable of suspending the first louver and a second suspension portion capable of suspending the second louver. The first suspension portion and the second suspension portion support the first and second louvers at different angles on both sides of the shaft, and suspend the second louvers so that their ends are closer to the inside than the ends of the first louvers.

[0008] According to this configuration, the second louvers are suspended relative to the first louvers so that their ends are closer to the inner side than the ends of the first louvers. This brings the outer ends of the second louvers closer to the rotation axis, thereby reducing the amount of protrusion of the louvers during rotation. This allows vertical blinds to be installed in installation areas with small depth dimensions. Note that the number of louvers on each carrier is not limited to two, and in addition to the first and second louvers, third and fourth louvers may be installed. The angle between the first and second louvers with respect to the axis in a plan view is, for example, approximately 90 to 130 degrees, but is not limited to this. Furthermore, the inward position may be, for example, near the center of the first louver in the short direction, but is not limited to this.

[0009] The first suspending portion may be rotatable integrally with the shaft portion, and the second suspending portion may be rotatable integrally with the first suspending portion by at least a first predetermined amount.

[0010] According to this configuration, by allowing the first hanging portion and the second hanging portion to rotate integrally by a predetermined amount, the first louver and the second louver can be rotated integrally until the louvers rotate to a predetermined angle.

[0011] The shaft portion may have a biasing member that biases the second hanging portion in a rotational direction that follows the rotation of the first hanging portion.

[0012] With this configuration, the rotation of the second louver can be made to follow the rotation of the first louver.

[0013] The shaft portion may have a restricting portion that restricts rotation of the second hanging portion by more than the first predetermined amount.

[0014] With this configuration, once the first louver has rotated to a predetermined angle, the rotation of the second louver is restricted, preventing the second louver from rotating more than necessary. For example, it is not necessary to rotate the second louver to an angle perpendicular to the rail. The first predetermined amount is, for example, around 30 degrees, but is not limited to this.

[0015] The shaft portion may allow the first hanging portion to rotate a second predetermined amount when the rotation of the second hanging portion is restricted by the restricting portion.

[0016] With this configuration, even if the rotation of the second louver is restricted, the first louver is allowed to rotate up to a predetermined angle (for example, fully closed). By setting the allowable range of rotation in this way, even if the first louver reverses after rotating up to the allowable range (fully closed), it can rotate integrally with the second louver from the set predetermined angle. The second predetermined amount is, for example, around 60 degrees, but is not limited to this.

[0017] The length of the second louver in the short side direction may be smaller than the length of the first louver in the short side direction.

[0018] With this configuration, the width (length in the short direction) of the second louvers is shorter than the width of the first louvers, making it less likely for the second louvers to interfere with the first louvers during rotation, ensuring their rotation performance and further reducing the amount of protrusion of the second louvers during rotation. The width of the first louvers is, for example, approximately 100 mm, and the width of the second louvers is, for example, approximately 90 mm, but is not limited to these. [Effects of the Invention]

[0019] As described above, the present invention provides a vertical blind that can reduce the amount of protrusion of the louvers at least on the indoor or outdoor side. However, this effect does not limit the present invention. [Brief explanation of the drawings]

[0021] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0022] [Vertical blinds configuration] Fig. 1 is a front view of a vertical blind according to one embodiment of the present invention, with the opening closed by a first louver (described below), and Fig. 2 is a front view of the vertical blind with the opening closed by a second louver (described below). Fig. 3 is a front view of the vertical blind with the louvers folded. Fig. 4 is a right side view of the vertical blind with the opening closed by the first louver, and Fig. 5 is a right side view of the vertical blind with the opening closed by the second louver. Fig. 6 is a plan view of the vertical blind with the opening closed by the first louver, and Fig. 7 is a plan view of the vertical blind with the opening closed by the second louver.

[0023] As shown in these figures, the vertical blind 100 of this embodiment has a head rail 10 fixed to an opening such as a window frame by a bracket 9, a plurality of carriers 12 that can slide longitudinally on the head rail 10, and a first louver 15 and a second louver 16 suspended from each carrier 12 via a carrier shaft portion 121 (see Figures 6 and 7) and a suspension member 5.

[0024] The suspending member 5 is rotatably connected to the carrier shaft portion 121, and is composed of a first suspending portion 13 capable of suspending the first louver 15 and a second suspending portion 14 capable of suspending the second louver 16.

[0025] That is, each carrier 12 suspends two louvers, and as shown in Figure 7, the first suspending portion 13 and the second suspending portion 14 support the first louver 15 and the second louver 16 at different angles on either side of the carrier axis portion 121.

[0026] As shown in Figures 5 and 7, each carrier 12 suspends the second louver 16 so that its end 16a is closer to the inside than the end 15a of the first louver 15 (near the center of the first louver 15 in the short direction).

[0027] The first louver 15 is provided on the front side (indoor side) of the vertical blind 100, and is made of an opaque fabric such as a drape fabric.

[0028] The second louvers 16 are provided on the rear side (outside the room) of the vertical blinds 100, and are made of a see-through fabric such as lace fabric.

[0029] Additionally, the width (length in the short direction) of second louvers 16 is formed to be smaller than the width of first louvers 15. For example, the width of first louvers 15 is approximately 100 mm, and the width of second louvers 16 is approximately 90 mm, but is not limited to this. This makes it less likely that second louvers 16 will interfere with first louvers 15 during rotation, ensuring their rotation performance.

[0030] Inside the head rail 10, there are provided a carrier movement mechanism that moves the carrier 12, and a louver rotation mechanism that rotates the first louver 15 and the second louver 16 integrally.

[0031] 7, the carrier at the front of the multiple carriers 12 is designated as a master carrier 12a. Adjacent carriers 12 are connected to each other by spacer links 17 (see FIGS. 6 and 7) with the master carrier 12a at the front so that they can be spaced apart or moved closer together with a predetermined maximum distance determined by the length of the spacer links 17.

[0032] As shown in Figures 6 and 7, the carrier movement mechanism has an opening / closing cord 18. As shown in Figure 7, one end of the opening / closing cord 18 is connected to the master carrier 12a, and the other end is guided through the head rail 10 to the control unit 10a at one end of the head rail 10, hangs down from the control unit 10a, then turns around and is introduced back into the head rail 10, and is further guided to the end cover 10b (see Figures 1 to 3) at the other end of the head rail 10, then turns around at the end cover 10b, is guided through the head rail 10, and is connected to the master carrier 12a.

[0033] The exposed portion of the opening / closing cord 18 hanging down from the control unit 10a functions as an opening / closing operation unit 25 that opens and closes the first louver 15 and the second louver 16. A weight 27 is attached to the lower end (turning end) of the opening / closing operation unit 25.

[0034] When the user pulls one of the double portions of the opening / closing operation unit 25, the master carrier 12a is pulled by the opening / closing cord 18 and moves to one side or the other within the head rail 10. On the other hand, when the user pulls the other of the double portions of the opening / closing operation unit 25, the master carrier 12a is pulled by the opening / closing cord 18 and moves to the other side within the head rail 10.

[0035] From the folded state shown in Figure 3, as the master carrier 12a moves, the subsequent carriers 12 are pulled one after another via the spacer links 17 in accordance with the movement of the master carrier 12a, and the first louvers 15 and second louvers 16 can be expanded as shown in Figure 1.

[0036] On the other hand, when the master carrier 12a moves from the unfolded state shown in FIG. 1 and pushes out the carrier 12, the first louver 15 and the second louver 16 can be folded as shown in FIG. 3.

[0037] The louver rotation mechanism is composed of a drive shaft (tilt shaft) 24 (see Figures 6 and 7) that extends longitudinally within the head rail 10 and is rotatably supported, and a rotation operation unit (operation rod) 26 (see Figure 2) that is connected to the drive shaft 24 via a gear (not shown) that is disposed within the control unit 10a. The rotation operation unit 26 hangs down from the control unit 10a.

[0038] Each carrier 12 has a built-in rotation transmission mechanism that engages with the drive shaft 24, and the rotation transmission mechanism transmits the rotation of the drive shaft 24 by the rotation operating unit 26 to the carrier shaft portion 121 of the carrier 12, thereby rotating the first louver 15 and the second louver 16.

[0039] The vertical blind 100 of this embodiment uses the rotation transmission mechanism to rotate each louver between a state in which the first louver 15 closes an opening in a window frame or the like, and a state in which the second louver 16 closes the opening. However, although the first louver 15 and the second louver 16 rotate in conjunction with each other a predetermined amount from a state in which the second louver 16 closes the opening, thereafter only the first louver 15 rotates independently, and the opening is closed by the first louver 15, as will be described in detail later.

[0040] 1, 4, and 6 show a state in which the first louvers 15 are approximately parallel to the head rail 10 and close the opening with the first louvers 15. As mentioned above, the first louvers 15 are made of opaque fabric, so in this state, it is possible to prevent external light from entering through the opening.

[0041] 2, 5, and 7 show a state in which the angle of the second louvers 16 relative to the head rail 10 is at its smallest (the first louvers 15 are nearly perpendicular to the head rail 10), and the opening is closed by the second louvers 16. As mentioned above, the second louvers 16 are made of a see-through fabric, so in this state, it is possible to let in outside light through the opening while maintaining a certain degree of privacy.

[0042] [Detailed carrier configuration] Next, the carrier 12 will be described in detail. Fig. 8 is a side view of the carrier of the vertical blind 100. Fig. 9 is a cross-sectional view of the side of the inside of the head rail 10 when the opening is closed by the first louver 15 of the vertical blind 100. Fig. 10 is a cross-sectional view of the side of the inside of the head rail 10 when the opening is closed by the second louver 16 of the vertical blind 100. Fig. 11 is a cross-sectional view taken along line AA (Fig. 9(A)) and a cross-sectional view taken along line BB (Fig. 9(B)) of Fig. 9. Fig. 12 is a cross-sectional view taken along line CC (Fig. 9(A)) and a cross-sectional view taken along line DD (Fig. 9(B)) of Fig. 10.

[0043] As shown in these figures, carrier 12 incorporates a rotation transmission mechanism made up of worm 122, worm wheel 123, and friction spring 124 inside the case, and has vertical carrier shaft 121 at its bottom. Carrier shaft 121 protruding from the bottom end of the case is connected to suspension member 5 so as to be rotatable integrally therewith.

[0044] As described above, the hanging member 5 has a first hanging portion 13 and a second hanging portion 14, and a first hook portion 131 is formed at the end of the first hanging portion 13 so that the first louver 15 can be hung from it, and a second hook portion 141 is formed at the end of the second hanging portion 14 so that the second louver 16 can be hung from it.

[0045] First hook portion 131 and second hook portion 141 are formed to be non-parallel, whereby first louver 15 and second louver 16 are suspended at different angles as described above.

[0046] Additionally, first hook portion 131 and second hook portion 141 hang both louvers so that end portion 16a of second louver 16 is close to the center of first louver 15 in the width direction (FIG. 7). This minimizes the gap between the two louvers, reducing light leakage from the gap.

[0047] 9 and 10, first suspending portion 13 is provided integrally with carrier shaft portion 121, and the two are rotatable integrally, while second suspending portion 14 is not connected to carrier shaft portion 121 but is connected only to first suspending portion 13, and is rotatable integrally with first suspending portion 13 by a first predetermined amount (a predetermined angle). The first predetermined amount is, for example, around 30 degrees, but is not limited to this.

[0048] Specifically, as shown in each drawing, carrier shaft portion 121 has spring 125 as a biasing member that biases second suspending portion 14 in a rotational direction (counterclockwise) that follows the rotation of first suspending portion 13. This makes it possible for second louver 16 to rotate in accordance with the rotation of first louver 15.

[0049] Furthermore, carrier shaft portion 121 has restricting portion 126 that restricts rotation of second suspending portion 14 beyond the first predetermined amount. Restricting portion 126 is, for example, a fan-shaped columnar member that protrudes from around carrier shaft portion 121, but is not limited to this, and may be, for example, a stopper that protrudes from the bottom surface of carrier 12 or the like and abuts against second suspending portion 14 when second suspending portion 14 rotates the first predetermined amount.

[0050] Furthermore, carrier shaft portion 121 is configured to allow first hanging portion 13 to rotate a second predetermined amount when the rotation of second hanging portion 14 is restricted by restricting portion 126. The second predetermined amount is, for example, around 60 degrees, but is not limited to this. As a result, second louver 16 rotates integrally with first louver 15 up to the first predetermined amount, but any further rotation is restricted, and first louver 15 rotates independently by the second predetermined amount.

[0051] As shown in Figures 11 and 12, the second hanging part 14 has, at its connection end with the first hanging part 13, a first wall part 142 and a second wall part 143 that can abut against two flat parts at the end of the first hanging part 13 extending from below the carrier shaft part 121 depending on its rotational position.

[0052] 9 and 11, when the opening is closed by the first louver 15, the second hanging portion 14 is biased by the spring 125 to rotate counterclockwise, but abuts against the restricting portion 126 and cannot rotate further counterclockwise. As a result, even if the first hanging portion 13 rotates further, the second louver 16 cannot rotate following the first louver 15. In the state shown in the figures, the first hanging portion 13 also abuts against the second wall portion 143 and is restricted from rotating further.

[0053] 10 and 12, when the opening is closed by the second louver 16, the second hanging portion 14 is biased to rotate counterclockwise by the spring 125, but the first wall portion 142 abuts against the flat portion of the first hanging portion 13, and the second hanging portion 14 cannot rotate counterclockwise any further (by itself). From this state, if the first hanging portion 13 (first louver 15) rotates, the second hanging portion 14 (second louver 16) can also rotate following it until it abuts against the restricting portion 126.

[0054] This configuration allows the first louver 15 and the second louver 16 to rotate together until both louvers rotate to a predetermined angle, while preventing the second louver 16 from rotating more than necessary. For example, since the second louver 16 does not need to be rotated to an angle perpendicular to the head rail 10 to perform its shielding function, restricting the rotation of the second louver 16 at a certain position can reduce the amount of protrusion of the louver in the front-to-rear direction of the vertical blind 100 when rotated.

[0055] Furthermore, even if the rotation of the second louver is restricted, the first louver 15 is allowed to rotate up to a predetermined angle (for example, fully closed), so that if the first louver 15 rotates up to the allowable range (fully closed) and then reverses, it will be able to rotate again integrally with the second louver 16 from the set predetermined angle.

[0056] [Vertical blinds operation] Next, we will explain the operation of the vertical blind 100 configured as above. Figures 13A to 13F are plan views (partial cross-sectional views) showing the opening and closing operation of the louvers of the vertical blind 100. Each figure also shows an enlarged partial view of the vicinity of the carrier shaft portion 121 in the cross-sectional views corresponding to the cross-sectional views shown in Figures 11 and 12.

[0057] As shown in Figure 13A, when the opening is closed by the second louver 16, as described above, the second hanging part 14 is biased to rotate counterclockwise by the spring 125, but the first wall part 142 abuts against the flat part of the first hanging part 13 and cannot rotate further counterclockwise (by itself).

[0058] From this state, when the first louver 15 is rotated in the closing direction (counterclockwise direction) using the rotation operating unit 26, as shown in Figure 13B, the second hanging portion 14 rotates together with the first hanging portion 13 with the first wall portion 142 abutting against the first hanging portion 13 due to the force of the spring 125, and the second louver 16 rotates following the first louver 15.

[0059] When the first louver 15 is further rotated in the closing direction, as shown in Figure 13C, the second hanging portion 14 abuts against the regulating portion 126, thereby restricting the rotation of the second louver 16 and allowing only the rotation of the first hanging portion 13 (first louver 15).

[0060] When first louver 15 is further rotated in the closing direction from this state, only first hanging portion 13 rotates, and first hanging portion 13 moves away from first wall portion 142 of second hanging portion 14, as shown in FIG. 13D.

[0061] 13E, when first louver 15 continues to rotate, first hanging portion 13 abuts against second wall portion 143 of second hanging portion 14, restricting the rotation of first louver 15. This state is the state in which the opening is closed by first louver 15.

[0062] From this state, when opening / closing operation unit 25 is operated in the folding direction, first louver 15 and second louver 16 can be folded as shown in FIG. 13F.

[0063] From this state, by operating the opening / closing operation unit 25 in the unfolding direction, the unfolded state shown in Figure 13E (the opening is closed by the first louver 14) can be achieved, and from this state, by operating the rotation operation unit 26 again in the opposite direction (opening direction) to the above, the first louver 15 and the second louver 16 can be rotated to each of the states shown in Figures 13D, 13C, 13B, and 13A.

[0064] FIG. 14 is a diagram for comparing the rotation locus of the louvers of the vertical blind 100 with that of the prior art.

[0065] As shown in the figure, the vertical blind 100 according to this embodiment has a smaller amount of projection in the front-to-rear direction at both the maximum projection position P1 on the indoor side and the maximum projection position P2 on the outdoor side compared to the prior art. The length from the center line of the head rail 10 in the longitudinal direction to P1 (maximum projection) is, for example, 57 mm, and the length from the center line to P2 (maximum projection) is, for example, 60 mm (compared to 82 mm on both the indoor and outdoor sides in the prior art).

[0066] This is because, in the prior art, the end C1a of the first louver C1 and the end C2a of the second louver C2 are arranged close to each other, whereas in this embodiment, the second louvers 16 are suspended from the first louvers 15 so that their ends 16a are closer to the inner side (near the center in the width direction) than the ends 15a of the first louvers 15, so that the outer ends of the second louvers 16 are closer to the rotation axis (carrier shaft portion 121). Also, although it depends on the angle between the louvers, as mentioned above, the width (length in the short direction) of the second louvers 16 being shorter than the width of the first louvers 15 can also be a factor in reducing the amount of protrusion.

[0067] In this manner, in this embodiment, the amount of protrusion of the louvers during rotation can be reduced, so that the vertical blind 100 can be attached to an attachment portion with a small depth dimension.

[0068] <Modification> The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit and scope of the present technology.

[0069] For example, the angles of the first louvers 15 and second louvers 16 provided in the first hanging portion 13 and the second hanging portion 14 (the installation angles of the first hook portion 131 and the second hook portion 141) are not limited to those shown in the above-mentioned embodiments.

[0070] Furthermore, in the above-described embodiment, the carrier shaft portion 121 is designed to be located at the top of the space where the first louver 15 and the second louver 16 form an obtuse angle in a plan view, but the carrier shaft portion 121 may also be designed to be located at the top of the space where the first louver 15 and the second louver 16 form an acute angle, as shown in Fig. 15. In this case, the angle formed between the first louver 15 and the second louver 16 with the carrier shaft portion 121 as the reference in a plan view is, for example, about 40 to 85 degrees.

[0071] In the first and second embodiments described above, the first louvers 14 are made of drape fabric and the second louvers 15 are made of lace fabric, but they may be made of fabrics of other materials, metals such as aluminum, wood, or resin. Also, the first louvers 14 and the second louvers 15 may be the same.

[0072] In the above-described embodiment, the opening / closing cord 18 looped inside the head rail 10 was used as the carrier movement mechanism for moving the carriers 12 to open and close the first louvers 14 and the second louvers 15. However, instead of this, an opening / closing shaft (screw shaft) passing through each carrier 12 may be used. In this case, a pulley is provided around which a cord is wound as an opening / closing operation unit, and the master carrier 12a and the opening / closing shaft are screwed together, and the opening / closing shaft rotates in conjunction with the rotation of the pulley, thereby moving the master carrier 12a and the other carriers 12 pulled by it.

[0073] In the above-described embodiment, two louvers are provided for one carrier 12 (hanging member 5). However, three or more louvers may be suspended from one carrier 12 (hanging member 5). For example, in addition to the first louver 15 and second louver 16 shown in the above-described embodiment, another louver (and a suspension part) may be provided symmetrically to the second louver 16 relative to the first louver 15.
