However, in the technique described in Patent Document 1, the end portion of the second suspension plate is attached to at least one end of the first suspension plate, and the first suspension plate and the second suspension plate are attached. Since the connecting shaft with the hanging plate is deviated from the rotation axis of the slat, when the slat is rotated, the rotation locus deviates from the center line of the head rail to the front and rear, and the slat is located on the indoor side or on the indoor side. There is a problem that the amount of protrusion to the outdoor side becomes large.

In view of the above circumstances, an object of the present invention is to suspend a plurality of louvers with one carrier and to make the amount of protrusion of the louvers in the front-rear direction uniform between the indoor side and the outdoor side. To provide type blinds.

In order to achieve the above object, the vertical blind according to one embodiment of the present invention has a plurality of carriers which have a shaft portion and can move in the longitudinal direction in the head rail, and the said shaft portion from each of the plurality of carriers. It has a plurality of louvers suspended via. Each of the carriers has a plurality of support portions capable of suspending the plurality of louvers, and has a suspension member rotatably connected to the shaft portion. The plurality of support portions support the plurality of louvers at different angles on both sides of the shaft portion as a boundary.

According to this configuration, the hanging member supports the plurality of louvers at different angles on both sides of the carrier shaft portion, so that the plurality of louvers are arranged on both sides of the shaft portion. , The amount of protrusion of the head rail in the front-rear direction when the louver rotates can be made uniform on the indoor side and the outdoor side.

The plurality of louvers may have a first louver and a second louver. In this case, the plurality of support portions may support the axis of the center of gravity in each of the width directions of the first louver and the second louver.

According to this configuration, the support portion of the hanging member supports the axis of the center of gravity in each of the width directions of the first louver and the second louver, so that the first louver and the second louver are not cantilevered and are stable. Suspended in the state.

The plurality of support portions may be provided so that one edge portion of the first louver and the other edge portion of the second louver can be suspended in close proximity to each other.

According to this configuration, the gap between the two louvers is minimized without connecting the first louver and the second louver to each other, thereby reducing light leakage between the two louvers and when the louvers are suspended. Workability can be improved.

The plurality of support portions may be provided so that the first louver and the second louver can be suspended so that the angle between the first louver and the second louver is approximately 90 degrees.

According to this configuration, by setting the sandwiching angle between the first louver and the second louver to be approximately 90 degrees, it is only necessary to rotate the shaft portion of the carrier by 90 degrees in the axial direction of the rail, and the first louver is first. It is possible to switch between a state in which the louvers are substantially parallel and a state in which the second louver is substantially parallel to the rail. Further, when the fabrics of the first louver and the second louver are different, it is possible to prevent the louvers in the back from being exposed from between the louvers in the foreground and the design from being deteriorated at the time of the above switching.

The plurality of support portions may have a first hook portion that supports the first louver and a second hook portion that supports the second louver.

According to this configuration, since the support portion of the hanging member is made up of two hook portions, the suspension is completed simply by hooking the louvers on each hook portion, so that the work at the time of suspending the first and second louvers is completed. Can improve sex.

The first hook portion and the second hook portion may be formed in a state of facing directions substantially 90 degrees different from each other.

According to this configuration, the sandwiching angle between the first louver and the second louver can be set to approximately 90 ° simply by suspending the first and second louvers on each hook portion of the hanging member.

As described above, according to the present invention, a plurality of louvers can be suspended by one carrier, and the amount of protrusion of the louvers in the front-rear direction can be made uniform between the indoor side and the outdoor side.

As shown in these figures, the vertical blind 100 according to the present embodiment includes a head rail 10 fixed to an opening such as a window frame by a bracket 9, and a plurality of head rails 10 capable of sliding in the longitudinal direction. The carrier 12 and the first louver 14 and the second louver 15 suspended from each carrier 12 via a hanging member 13.

That is, each carrier 12 suspends two louvers, and details will be described later. As shown in FIGS. 4, 7, and 8, the first louver 14 and the second louver 15 are edges thereof. It is attached to the hanging member 13 so that the (long sides) are close to each other and the sandwiching angle formed by the main surfaces thereof is approximately 90 degrees (for example, 95 degrees in the case of the present embodiment).

The first louver 14 is provided in front of the vertical blind 100 (indoor side), and is formed of an opaque fabric such as a drape fabric.

The second louver 15 is provided behind (outdoor) the vertical blind 100 and is formed of a see-through fabric such as a lace fabric.

A carrier moving mechanism for moving the carrier 12 and a louver rotating mechanism for integrally rotating the first louver 14 and the second louver 15 are provided in the head rail 10.

The carrier moving mechanism has an opening / closing cord 18 as shown in FIGS. 1, 7 and 8. As shown in FIG. 1, 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 to control unit 10a. After being hung from the head rail 10, it is turned and introduced into the head rail 10 again, and after being guided to the end cover 10b at the other end of the head rail 10, it is turned by the end cover 10b and turned to the head rail 10. Guided inside, it is connected to the master carrier 12a.

The portion of the opening / closing cord 18 that hangs down from the control unit 10a and is exposed functions as an opening / closing operation unit 25 that rotates the first louver 14 and the second louver 15. A weight 27 is attached to the lower end (turning end) of the opening / closing operation unit 25.

As shown in FIGS. 1 and 8, the leading carrier among the plurality of carriers 12 is the master carrier 12a. Adjacent carriers 12 are connected by spacer links 16 with the master carrier 12a at the head so that they can be separated or approached with a predetermined interval determined by the length of the spacer links 16 as the maximum interval.

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 in the head rail 10 to either one. 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 in the head rail 10 to either one.

As shown in FIG. 7, when the subsequent carrier 12 is towed one after another via the spacer link 16 in response to the movement of the master carrier 12a due to the movement of the master carrier 12a, the first louver 14 and the second louver 15 are pulled. Can be put into a stretched state as shown in FIG.

On the other hand, when the master carrier 12a pushes out the carrier 12 by moving the master carrier 12a, the first louver 14 and the second louver 15 can be brought into a folded state as shown in FIG.

The louver rotation mechanism is attached to the drive shaft 24 via a drive shaft (tilt shaft) 24 that extends in the longitudinal direction and is rotatably supported in the head rail 10 and a gear (not shown) arranged in the control unit 10a. It is composed of a rotation operation unit (operation rod) 26 to be connected. The rotation operation unit 26 hangs down from the control unit 10a.

Each carrier 12 is provided with a rotation transmission mechanism that meshes with the drive shaft 24, and the rotation transmission mechanism transmits the rotation of the drive shaft 24 by the rotation operation unit 26 to the carrier 12, and the first louver 14 and the first louver 14 2 The louver 15 can be rotated.

The states shown in FIGS. 1, 5, 7 and 8 indicate a neutral state in which the first louver 14 and the second louver 15 both have a sandwich angle of approximately 45 degrees with respect to the longitudinal direction of the head rail 10. ..

On the other hand, in FIG. 3, the first louver 14 and the second louver 15 are rotated approximately 45 degrees counterclockwise in FIG. 7 from the neutral state, and the first louver 14 is parallel to the head rail 10 (the second louver 15 is the head). It is perpendicular to the rail 10) and the opening is closed. As described above, since the first louver 14 is made of an opaque material, it is possible to prevent outside light from entering through the opening in this state.

Further, in FIGS. 4 and 6, the first louver 14 and the second louver 15 are rotated by approximately 45 degrees clockwise from the neutral state of FIG. 7, and the second louver 15 is parallel to the head rail 10 (the first louver 14 is parallel to the head rail 10). It is perpendicular to the head rail 10) and the opening is closed. As described above, since the second louver 15 is formed of the see-through fabric, in this state, outside light can be taken in from the opening while maintaining privacy to some extent.

[Carrier composition]
Next, the details of the carrier 12 will be described. FIG. 9 is a perspective view of the carrier 12, and FIG. 10 is a cross-sectional view of the inside of the head rail 10 and the carrier 12 in the X direction. Of these, FIGS. 9A and 10A show the neutral state of the first louver 14 and the second louver 15 (FIGS. 1, 5, 7, and 8), and FIGS. 9B and 10B show the second louver 15. A state in which the opening is closed is shown (FIGS. 4 and 6). 11 is a cross-sectional view taken along the line AA of FIG. 9, and FIG. 12 is a cross-sectional view taken along the line BB of FIG.

As shown in these figures, the carrier 12 has a rotation transmission mechanism including a worm 122, a worm wheel 123, and a friction spring 124 built in the case, and has a carrier shaft portion 121 in the vertical direction below the rotation transmission mechanism. The hanging member 13 is integrally rotatably connected to the carrier shaft portion 121 protruding from the lower end of the case. The hanging member 13 has an elongated shape, and is connected to the carrier shaft portion 12 so as to allow the hanging member 13 to tilt in the longitudinal direction, but to restrict tilt in the lateral direction. To. A spacer 125 is interposed on the upper surface of the hanging member 13 so as to fill a clearance between the carrier 12 and the lower surface of the case, and the spacer 125 restricts the upward movement of the hanging member 13.

At both ends of the hanging member 13, a first hook portion 131 as a first support portion and a second hook portion 132 as a second support portion capable of suspending the first louver 14 and the second louver 15, respectively, are provided. Have.

That is, the first hook portion 131 and the second hook portion 132 support the first louver 14 and the second louver 15 on both sides in the longitudinal direction of the hanging member 13 with the carrier shaft portion 121 as a boundary.

The first hook portion 131 and the second hook portion 132 are formed in a state of facing directions substantially 90 degrees different from each other. As a result, as described above, the sandwiching angle between the first louver 14 and the second louver 15 becomes approximately 90 degrees.

As a result, the hanging operation is completed only by hooking the first louver 14 and the second louver 15 on the first hook portion 131 and the second hook portion 132, and the sandwiching angle between the first louver 14 and the second louver 15 is completed. Can be set to approximately 90 °.

Further, in the axial direction of the head rail 10, the first louver 14 is substantially parallel to the head rail 10 and the second louver 15 is substantially parallel to the head rail 10 simply by rotating the carrier shaft portion 121 by 90 degrees. Can be switched between a state in which is approximately parallel and a state in which

At the same time, as shown in FIGS. 3 and 4, when the parallel state is switched, only one louver is exposed in front of the vertical blind 100, so that the louvers in the back are exposed from between the louvers in the foreground and the design. It is possible to prevent the sex from getting worse.

As shown in FIGS. 1, 7 and 8, the first hook portion 131 and the second hook portion 132 support the axis of the center of gravity of the first louver 14 and the second louver 15 in the respective width directions. There is. As a result, the first louver 14 and the second louver 15 are not cantilevered and are hung in a stable state.

Further, as described above, the first hook portion 131 and the second hook portion 132 suspend one edge of the first louver 14 and the other edge of the second louver 15 in close proximity to each other (FIG. FIG. 7, Fig. 8). As a result, the gap between the two louvers is minimized, light leakage from the gap is reduced, and workability when the louvers are suspended is improved.

Further, as shown in FIGS. 9 and 10, the hanging member 13 is between the hanging member 13 and the head rail 10 by contacting the bottom surface of the head rail 10 with the head rail 10 on the upper surface thereof. It has two tilt suppressing portions 133 capable of suppressing the relative tilt of the above.

As shown in FIG. 9, in the present embodiment, the tilt suppressing portion 133 is formed as a mountain-shaped convex portion (protrusion) having an apex on the center line in the width direction of the hanging member 13. The tilt suppressing portion 133 is integrally formed with the hanging member 13. Instead of this, the tilt suppressing portion 133 may be formed separately from the hanging member 13 by fitting, bonding, or the like using a material having a low friction coefficient.

As described above, in the present embodiment, the first louver 14 is formed of the drape cloth and the second louver 15 is made of the lighter lace cloth. Therefore, when the hanging member 13 (louver) is rotated or moved, the louver 14 is formed of the drape cloth. The suspension member 13 is likely to tilt due to the balance difference. Further, the suspension member 13 may be tilted depending on the operation speed of the user or other factors.

Here, the tilt angle of the hanging member 13 during rotation or movement becomes smaller as the clearance between the hanging member 13 and the head rail 10 becomes smaller. In that case, the hanging member 13 and the head rail become smaller. It becomes easy for the 10 to come into contact with each other, and the resistance between the two becomes large, which may hinder smooth rotation and movement.

Therefore, in the present embodiment, the suspension member 13 is tilted during rotation or movement by positively forming a clearance between the suspension member 13 and the head rail 10 and providing a tilt suppressing portion 133 between the two. In this case, the tilt suppressing portion 133 makes point contact with the bottom surface of the head rail 10, so that the hanging member 13 (louver) can be smoothly rotated or moved while suppressing tilt.

The two tilt suppressing portions 133 are formed on both sides of the suspension member 13 in the longitudinal direction with the carrier shaft portion 121 as a boundary. More specifically, each tilt suppressing portion 133 is formed slightly inside (on the carrier shaft portion 121 side) from the intermediate position between both end portions of the suspension member 13 of FIG. 10A and the carrier shaft portion 121. The formation position of the tilt suppressing portion 133 is not limited to this position, but by providing the hanging member 13 on both sides of the carrier shaft portion 121 on the inner side, the hanging member 13 is rotated or moved. Regardless of which direction 13 tilts in the front-rear direction of the head rail 10, the resistance between the head rail 10 and the head rail 10 can be further reduced while suppressing the tilt.

[Operation of vertical blinds]
Next, the operation of the vertical blind 100 configured as described above will be described. FIG. 13 is a schematic plan view showing an opening / closing operation of the first louver 14 and the second louver 15 of the vertical blind 100.

As shown in FIG. A, when the user pulls one of the cords of the opening / closing operation unit 25 from the state where the first louver 14 and the second louver 15 are folded, the master carrier 12a is pulled by the opening / closing cord 18. As the vehicle moves in the head rail 10, the subsequent carriers 12 are towed one after another via the spacer link 16 to pull the first louver 14 and the second louver 15 as shown in FIG. B. Can be deployed.

Further, when the user rotates the rotation operation unit 26 in one direction from the unfolded state (and the neutral state) shown in FIG. B, the first louver 14 and the second louver 15 are flat as shown in FIG. C. When it rotates counterclockwise in the visual sense and rotates approximately 45 degrees, the first louver 14 on the indoor side becomes substantially parallel to the head rail 10, and the second louver 15 on the outdoor side becomes approximately vertical to the head rail 10. The opaque first louver 14 can shield an opening such as a window. At this time, a design is realized in which the second louver 15 is not exposed between the adjacent first louvers 14.

On the other hand, when the user rotates the rotation operation unit 26 in the other direction from the deployed state (and the neutral state) shown in FIG. B, the first louver 14 and the second louver 15 are viewed in a plan view as shown in FIG. D. When the first louver 14 on the indoor side is substantially perpendicular to the head rail 10 and the second louver 15 on the outdoor side is substantially parallel to the head rail 10, the first louver 14 on the indoor side is substantially parallel to the head rail 10 when the first louver 14 on the indoor side is rotated clockwise. The transparent second louver 15 allows outside light to be taken in through an opening such as a window.

[Summary]
As described above, according to the present embodiment, the first hook portion 131 and the second hook portion 132 at both ends of the hanging member 13 have the first louver 14 and the second hook portion 132 on both sides of the carrier shaft portion 121 as a boundary. By instructing the louvers 15 so that their sandwiching angles are approximately 90 degrees, the louvers are arranged on both sides of the carrier shaft portion 121, and the amount of protrusion of the head rail 10 in the front-rear direction when the louvers rotate. Can be made uniform on the indoor side and the outdoor side.

Further, by providing the tilt suppressing portion 133 that suppresses the relative tilt between the hanging member 13 and the head rail 10, the first louver 14 and the second louver 15 with respect to the hanging member 13 are provided. Even if the hanging member 13 tries to tilt due to balance or the like, the tilt suppressing portion 133 suppresses the tilting, and smooth rotation and movement of the first louver 14 and the second louver 15 can be realized.

<Second Embodiment>
Next, the second embodiment of the present invention will be described. In this embodiment and subsequent embodiments, the same reference numerals are given to the parts having the same functions as those in the first embodiment.

FIG. 14 is a bottom perspective view of the carrier of the vertical blind according to the present embodiment. Further, FIG. 15 is a side sectional view of the vertical blind according to the present embodiment in the head rail.

In the first embodiment, the tilt suppressing portion 133 is formed on the upper surface of the hanging member 13. On the other hand, in the present embodiment, as shown in both figures, the tilt suppressing portion 133 is provided on both sides of the bottom surface of the head rail 10 in the lateral direction (Z direction) in the longitudinal direction (X direction) of the head rail 10. It is formed as a ridge parallel to.

As shown in FIG. 15, the position of the tilt suppressing portion 133 in the width direction (Z direction) of the head rail 10 corresponds to the position of the tilt suppressing portion 133 provided on the upper surface of the hanging member 13 in the first embodiment. doing. Further, in the present embodiment, the tilt suppressing portion 133 is integrally formed with the head rail 10. Instead, the tilt suppressing portion 133 may be formed separately from the head rail 10 by welding, adhesion, or the like, but in any case, it is formed of the same material as the head rail 10 (for example, a metal having a low coefficient of friction such as aluminum). Will be done.

By providing the tilt suppressing portion 133 on the bottom surface of the head rail 10 in this way, the tilting of the hanging member 13 during rotation or movement of the first louver 14 and the second louver 15 is suppressed, and the first louver 14 and The smooth rotation and movement of the second louver 15 can be realized.

<Third Embodiment>
Next, a third embodiment of the present invention will be described.

FIG. 16 is a plan view of the vertical blind louver according to the present embodiment in a neutrally deployed state. Further, FIG. 17 is a plan view of the vertical blind louver according to the present embodiment in a state where the opening is closed by the second louver.

In the above-described first embodiment, the sandwiching angle between the first louver 14 and the second louver 15 is set to be approximately 90 degrees, but the sandwiching angle is not limited to 90 degrees and may be an angle exceeding 90 degrees. .. For example, in the vertical blind 200 according to the present embodiment, as shown in both figures, the sandwiching angle between the first louver 14 and the second louver 15 is approximately 110 degrees. This is realized by providing the first hook portion 131 and the second hook portion 132 so as to face in different directions by approximately 110 degrees.

From the neutral state shown in FIG. 16, as shown in FIG. 17, when the first louver 14 and the second louver 15 are rotated clockwise by approximately 70 degrees in a plan view, the second louver 15 is substantially parallel to the head rail 10. Therefore, the semi-transparent second louver 15 allows external light to be taken in from the opening.

At this time, since the first louver 14 is not perpendicular to the head rail but is inclined at an angle of about 20 degrees, the light taken in from the second louver 15 is biased to one side on the indoor side. That is, by making the sandwich angle between the first louver 14 and the second louver 15 larger than 90 degrees, the light taken into the room can be given directivity to some extent. As a result, for example, when there are a plurality of users in the room, it is possible to take in or block external light depending on the position of the users.

<Combination of different forms of louvers>
The vertical blind 100 according to the first embodiment and the vertical blind 200 according to the third embodiment can be appropriately selected and used according to the position of the opening of one building.

FIG. 18 is a diagram showing an example of a combination of such a vertical blind 100 and a vertical blind 200.

As shown in the figure, of the plurality of openings O of the building, the vertical blind 100 (interval angle of about 90 degrees) according to the first embodiment is installed in the opening Os located on the south side, and the east side and the opening Os. Vertical blinds 200 (narrowing angle of about 110 degrees) according to the third embodiment are installed in both openings Oe and Ow located on the west side.

As a result, when the vertical blinds 100 and 200 are rotated so that the second louver 15 is parallel to the opening O, the sunlight Ss emitted from the opening Os on the south side is emitted from directly above the daytime time zone. Is efficiently taken in, and sunlight Se and Sw shining diagonally in the morning and evening hours are efficiently taken in along the diagonal first louver 14 from the opening Oe on the east side and the opening Ow on the west side.

In this way, the amount of daylight taken in can be increased by properly using the vertical blinds having different sandwiching angles between the first louver 14 and the second louver 15 for each direction.

<Modification example>
The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present technology.

In the first and second embodiments described above, the first louver 14 is a drape fabric and the second louver 15 is a lace fabric, but fabrics of other materials may be adopted.

In the above-described embodiment, the opening / closing cord 18 provided in the head rail 10 in a loop shape is used as the carrier moving mechanism for moving the carrier 12 for opening / closing the first louver 14 and the second louver 15. Instead of this, an opening / closing shaft (screw shaft) penetrating each carrier 12 may be used. In this case, a pulley around which a cord as an opening / closing operation unit is wound is provided, the master carrier 12a and the opening / closing shaft are screwed, and the opening / closing shaft rotates in conjunction with the rotation of the pulley to be pulled by the master carrier 12a and the opening / closing shaft. The other carrier 12 moves.

In each of the above-described embodiments, the sandwiching angle between the first louver 14 and the second louver 15 is set by the angle at which the first hook portion 131 and the second hook portion 132 are provided. Instead of this, for example, hook portions capable of rotating and fixing 360 degrees around the vertical axis are provided at both ends of the hanging member 13, and the sandwiching angles of the first louver 14 and the second louver 15 are manually adjusted as appropriate. You may.
