Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a vertical blind according to an embodiment of the present invention. The vertical blind has a head rail 10 fixed to a window frame or the like, and a plurality of carriers 12 are arranged to be slidable in the head rail 10 in the longitudinal direction. A louver 14 is suspended from each carrier 12 via a hook 13. The leading carrier among the plurality of carriers 12 is the master carrier 12A. Adjacent carriers 12 are connected with the master carrier 12A at the head so that they can be separated or approached with a predetermined interval determined by the spacer as a maximum interval.

  A carrier moving mechanism that moves the carrier 12 and a louver rotating mechanism that rotates the louver 14 are disposed in the head rail 10. Although any known mechanism can be adopted as these mechanisms, in this embodiment, the carrier moving mechanism is connected to the master carrier 12A and arranged in the head rail 10, and one end portion of the head rail 10 is provided. The open / close cord 30 is led to the control unit 10c located at the center and partly led out from the control unit 10c. When the opening / closing cord 30 derived from the control unit 10c is pulled to one side, the master carrier 12A is pulled by the opening / closing cord 30 to move to one of the head rails 10, and when the opening / closing cord 30 is pulled to the other side, The carrier 12 </ b> A is pulled by the opening / closing cord 30 and moves in the head rail 10 to one of the other. Further, the subsequent carrier 12 is also pulled one after another through the spacer or pushed out by the master carrier 12A according to the movement of the master carrier 12A, and moves in the same direction as the master carrier 12A. It has become.

  In this embodiment, the louver rotation mechanism includes a tilt rod 32 pivotally supported in the head rail 10 and a tilt rod 32 disposed in the control unit 10c and connected to the tilt rod 32 via a gear such as a bevel gear. The operation rod 34 is suspended from one end of the head rail 10, and each carrier 12 is provided with a rotation transmission mechanism that meshes with the tilt rod 32. The rotation transmission mechanism transmits the rotation of the tilt rod 32 to the hook 13 of the carrier 12. When the operation rod 34 is operated and rotated, the rotation is transmitted to the tilt rod 32, whereby the hook 13 of each carrier 12 is rotated via the rotation transmission mechanism in the carrier 12 and the louver 14 is rotated. Be able to.

  A holding tool 16 is provided on the end louver 14B suspended from the end carrier 12B located on the opposite side of the master carrier 12A in the carrier 12. The end carrier 12 </ b> B can be configured not to move with respect to the head rail 10.

  As shown in FIG. 2, the holder 16 includes a holder body 18 that can be directly attached to the end louver 14B, an arm 20 that is rotatably provided to the holder body 18, and a holder body. And a locking tool 22 for holding 18 in the end louver 14B.

  The holder main body 18 has a shape surrounding the insertion passage 18a through which the end louver 14B is inserted.

  The arm 20 has a U-shape having a pair of parallel parts, and the first parallel part 20a, which is one of the parallel parts, is rotatable around an axis parallel to the width direction of the louver 14. A portion having an L-shape comprising a central portion 20b corresponding to the central side and a second parallel portion 20c corresponding to the other parallel portion is formed around the axis. It can swing. The space formed between the L-shaped portions (20b, 20c) of the arm 20 and the holder main body 18 constitutes the accommodating portion 24 that accommodates the remaining louvers 14. The length of the central portion 20b that determines the length of the accommodating portion 24 in the head rail width direction is larger than the total thickness of all the louvers 14 except for the end louvers 14, and the thickness of all the carriers 12 in the head rail width direction. The length is set to be smaller than the total. Further, the arm 20 can hold its position with an appropriate fitting force with respect to the holder main body 18 when the L-shaped portion of the arm 20 is horizontally rotated by fitting means (not shown). It can be done.

  The locking device 22 has a wedge portion 22a having a wedge shape, and the wedge portion 22a is formed in the gap between the holding device body 18 and the louver 14B formed in the insertion path 18a of the holding device body 18. By inserting the holder main body 18 and the louver 14B, the holder main body 18 can be fixed to the louver 14B. In this way, the holder 16 can be attached to an arbitrary height position of the louver 14B.

  In the vertical blind constructed as described above, when the carrier moving mechanism is operated to completely move the master carrier 12A to the left side of FIG. In order to push out and bring all the carriers 12 to one side, the louver 14 is folded and the blinds are opened (FIG. 5 (a)). At this time, by using the holder 16 attached to the end louver 14B, the arm 20 is swung so that the L-shaped portion is horizontal. In this way, when the remaining louver 14 is wound around from the portion without the arm 20 and accommodated in the formed accommodating portion 24, the tatami allowance of the louver 14 corresponds to the central portion 20b of the arm in the head rail width direction. Since this length is about the length, which is shorter than the total thickness of all the carriers 12, the opening when the blind is opened can be enlarged, and a large amount of external light can be taken in. (FIGS. 4 and 5B). Further, the louvers do not move apart due to the wind, and the influence of the wind can be reduced.

  Since the holder 16 is attached to the end louver 14B, it does not depend on the surrounding environment to which the blind is attached, unlike being attached to a fixed surface such as a window frame.

  When the holder 16 is not used, the arm 20 may be rotated and folded so that the L-shaped portion is vertical. This prevents the arm 20 from obstructing the opening and closing of the blind. it can. Furthermore, when it is unnecessary, the holder 16 itself can be detached from the louver 14B. At this time, the locking tool 22 can be easily removed by pulling it out from the insertion passage 18a. In addition, after removing the locking tool 22, the holding tool body 18 is moved relative to the louver 14 </ b> B along the insertion path 18 a of the holding tool body 18, and then the locking tool 22 is attached again. 16 can be moved up and down with respect to the louver, and its height position can be easily adjusted.

  The holder 16 of the present invention is preferably provided in the end louver 14B at the end on the side where the louver is folded, but is not necessarily limited to this, and the louver next to the end louver 14B is not necessarily limited thereto. Alternatively, it is possible to provide a louver 14 at any other position to reduce the tatami allowance of some of the plurality of louvers 14.
