Description

  The present invention relates to a vertical blind.

  In conventional vertical blinds, the louver is suspended from each of a plurality of carriers that can move in the head rail. By moving the carriers to one side and concentrating all the carriers, the louver is folded on one side, The opening with the blinds can be fully opened, and the carriers with the vertical blinds can be fully extended by moving the carriers to the opposite side and dispersing all the carriers in the head rail and extending the louvers. Further, the amount of light taken from the opening can be adjusted by rotating each louver around the vertical axis. However, in such a conventional vertical blind, since the louver only rotates around the vertical axis, there is a problem that the change is scarce and dimming cannot be performed in the vertical direction.

  In order to solve such a problem, there is one described in Patent Document 1. According to this embodiment, the louver hung from each of a plurality of carriers has a semitransparent portion at the top and an opaque portion at the bottom. It consists of parts. A screen that can be opened and closed along the head rail and that can cover the translucent portion of the louver when closed is provided.

  However, in the configuration as in Patent Document 1, each louver is configured by integrally combining two fabrics, a fabric forming a translucent portion and a fabric forming an opaque portion. The combination of the two fabrics is determined by the user's first choice, and if the fabric color, pattern, function, or combination is to be changed later, the entire louver must be replaced.

  On the other hand, there is one described in Patent Document 2 in which the louvers are connected vertically and the upper and lower louvers are completely divided. According to this, a plurality of slats can be divided into a plurality of groups in the vertical direction, and the divided slats can be opened and closed independently for each group, and the lighting part and the light shielding part can be arbitrarily selected in the vertical direction. It can be done.

  However, also in Patent Document 2, the divided slats constituting the upper group and the divided slats constituting the lower group are integrally connected by a joint for connecting the two divided slats so as to be relatively rotatable with each other. It is difficult to freely change the combination of color, pattern and function. In addition, a gap is required between the divided slats that are connected to each other so that they can rotate relative to each other. Therefore, even if it is desired to completely shield with blinds, light leaks from this gap. There is a problem that.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front 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 22 is led to the control unit 10c at a portion of the control unit 10c and partly led out from the control unit 10c. When the opening / closing cord 22 derived from the control unit 10c is pulled to one side, the master carrier 12A is pulled by the opening / closing cord 22 to move to one of the head rails 10, and when the opening / closing cord 22 is pulled to the other, The carrier 12A is pulled by the opening / closing cord 22 so as to move 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 24 (see FIG. 2) that is rotatably supported in the head rail 10 and a gear such as a bevel gear disposed in the control unit 10c. And an operating rod 26 that is suspended from one end of the head rail 10. Each carrier 12 is provided with a rotation transmission mechanism that meshes with the tilt rod 24. The rotation transmission mechanism transmits the rotation of the tilt rod 24 to the hook 13 of the carrier 12. When the operation rod 26 is operated and rotated, the rotation is transmitted to the tilt rod 24, whereby the hook 13 of each carrier 12 is rotated via the rotation transmission mechanism of the carrier 12 and the louver 14 is rotated. Can be done.

  As shown in FIGS. 2 and 3, each louver 14 is composed of a plurality of louver units 14A and 14B arranged vertically via a connecting member 18, and the louvers 14 are arranged vertically above and below adjacent louver units 14A and 14B. The ends adjacent to each other are detachably connected to the connecting member 18.

  The connecting member 18 is made of a hard plastic resin or the like and is a thin plate and has a rectangular shape when viewed from the front. The upper locking portion 18a corresponding to the upper side of the rectangular shape and the lower engagement corresponding to the lower side of the rectangular shape. A stopper 18b and a central opening 18d formed between the upper locking portion 18a and the lower locking portion 18b are provided. A notch 18c that obliquely crosses the lower locking portion 18b and communicates the outside and the central opening 18d is formed at a portion closer to one side than the middle point of the lower locking portion 18b corresponding to the lower side. The width dimension of the central opening 18d is substantially equal to the width dimension of each louver unit 14A, 14B, the height dimension of the central opening 18d is small, and is about several times the wall thickness of the louver units 14A, 14B.

  As shown in FIG. 3, bag-like portions 14a and 14a (connected portions) having the same structure with both side portions opened by folded stitching are formed at the upper and lower ends of the louver units 14A and 14B, respectively. . Then, the upper locking portion 18a of the connecting member 18 is inserted into the lower bag-like portion 14a of the louver unit 14A through the notch 18c of the connecting member 18, and the upper end of the lower louver unit 14B has a bag-like shape. The lower locking portion 18b of the connecting member 18 is inserted into the portion 14a through the notch 18c of the connecting member 18, whereby the louver units 14A and 14B are connected up and down via the connecting member 18. Since the notch 18c is shifted from the middle point in the width direction and is inclined toward one side and is inclined, the insertion operation is easily performed.

  The upper locking portion 18a and the lower locking portion 18b are inserted over the entire width of each louver unit 14A, 14B and restrict the entire width of the louver units 14A, 14B, so that the louver units 14A, 14B are not rotatable relative to each other. It will be connected to. Further, since the height dimension of the central opening 18d is about several times the wall thickness of the louver units 14A, 14B, there is almost no vertical gap between the louver units 14A, 14B after connection.

  A louver hook 15 having a hook hole 15a hooked on the hook 13 is connected to the upper end of the uppermost louver unit 14A.

  Similarly to the connecting member 18, the louver hook 15 is made of hard plastic or the like, is a thin plate and has a rectangular shape when viewed from the front, has a hook hole 15a formed in a portion corresponding to the upper side, and further corresponds to the lower side. A locking portion 15b and a central opening 15d are provided. A notch 15c that obliquely crosses the locking portion 15b is formed in a portion closer to one side than the middle point of the locking portion 15b corresponding to the lower side. The width dimension of the central opening 15d is substantially equal to the width dimension of each louver unit 14A, 14B, the height dimension of the central opening 15d is small, and is approximately equal to or several times the wall thickness of the louver units 14A, 14B. .

  Thus, since the latching | locking part 15b of the louver hook 15 becomes the same structure as the lower latching | locking part 18b of the connection member 18, when connecting the louver hook 15 to the upper end of the uppermost louver unit 14A, The connecting method is the same as the connecting method of the connecting member 18, and the locking portion 15b of the louver hook 15 is inserted into the bag-like portion 14a at the upper end of the louver unit 14A through the notch 15c of the louver hook 15. Since the locking portion 15b is inserted over the entire width of the louver unit 14A and restricts the entire width of the louver unit 14A, the louver hook 15 and the louver unit 14A are connected to each other so as not to be relatively rotatable. Further, since the height dimension of the central opening 15d is approximately the same as the wall thickness of the louver units 14A and 14B or several times as large, there is no vertical gap between the louver hook 15 and the louver unit 14A after connection. Little formed.

  A weight 16 for holding the louver 14 in a tensioned state is connected to the lower end of the lowermost louver unit 14B.

  The weight 16 is made of hard plastic or the like, and a pair of inverted L-shaped pieces are symmetrically formed on both sides of the weight 16 from both sides in the width direction. The pair of inverted L-shaped pieces forms a locking portion 16a. Composed. The width dimension of the opening 16d surrounded by the inverted L-shaped piece is substantially equal to the width dimension of each of the louver units 14A and 14B, and the height dimension of the opening 16d is small and is substantially equal to or several times the thickness of the louver units 14A and 14B. It is about double.

  The locking portion 16a is inserted into the bag-like portion 14a at the lower end of the lowermost louver unit 14B through the space between the inverted L-shaped pieces that are the locking portions 16a. Since the locking portions 16a are formed on both sides in the width direction and restrict the entire width of the louver unit 14B, the louver unit 14B and the weight 16 are connected to each other so as not to rotate relative to each other. Further, since the height of the opening 16d is substantially the same as the wall thickness of the louver units 14A and 14B or several times as large, a vertical gap is almost formed between the louver unit 14B and the weight 16 after connection. Not.

  When the connection between the louver units, the louver unit and the louver hook, and the connection between the louver unit and the weight is released, the louver unit can be easily removed by the operation opposite to that described above. As described above, since the louver units 14A and 14B are easy to attach and detach, when the soiled part is generated, only the soiled louver unit can be washed or replaced for each louver unit.

  In this example, only the locking portion 16a in the weight 16 has a different connection structure with the louver unit, unlike the locking portion of the connecting member 18 and the louver hook 15, but the same in all the locking portions. It is also possible to simplify by adopting a connection structure. Further, as shown in the drawing, the connected portions at the upper and lower ends of each louver unit have the same structure, and each can be detachably connected to the engaging portions of the connecting member 18, the louver hook 15, and the weight 16. If so, compatibility is enhanced and effective. However, the connecting member 18 is not completely separate from the louver unit as in the illustrated example, but the connecting member is provided integrally with one louver unit, and the other louver unit is interposed via the connecting member. It is also possible to removably connect to one louver unit.

  Since the connecting member 18, the louver hook 15 and the weight 16 can be connected to each other so that the members cannot be rotated relative to each other and almost no vertical gap is formed, the rotation from the louver rotating mechanism is prevented. 15 to the weight 16 can be accurately transmitted, and the same rotational movement as that of a conventional louver made of one fabric can be performed, and light leakage from the louver can be prevented.

  In the present invention, the louver unit can be freely changed. For example, as in the example shown in FIG. 1, the upper louver unit 14A of the two louver units 14A and 14B is made of a translucent fabric, and the lower louver unit 14B is made of an opaque fabric so that it can be illuminated from above. As shown in FIG. 4, the upper and lower louver units 14A and 14B can be changed upside down so that the upper part can be shielded and the upper part can be shielded from below. It can also be changed to allow daylighting and viewing. Alternatively, the difference between the louver unit 14A and the louver unit 14B can be a difference in pattern, color, material, etc., instead of a difference in light shielding rate.

  Alternatively, since it is not necessary to configure the louver units in the same way for all louvers, as shown in FIG. 5, the order of the louver units arranged by the louvers is changed, or the louver units 14C and 14D shown in FIG. It is also possible to make a more complex combination like this. Alternatively, as in the louver unit 14E shown in FIG. 7, by changing the number of louver units arranged by the louvers, the lengths of the louvers are intentionally made uneven, and the design of the vertical blind can be changed. .

  Further, by unifying the length of each louver unit as a standard, the number of louver units to be used can be determined according to the product size of the vertical blind, and the louver length can be determined. This makes it possible to easily cope with various product dimensions.

  FIG. 8 is an enlarged view of one louver representing a modified example using different connecting members. The connecting member 18-1 in this example has a decorative surface 18e that divides a central opening 18d between the upper locking portion 18a and the lower locking portion 18b, and the decorative surface 18e has a certain length in the vertical direction. Thus, a louver surface is formed, and the decorative surface 18e is appropriately decorated.

  The connecting member 18-1 having the decorative surface 18e functions not only as a member for connecting the louver units but also as a member constituting the louver surface at the center of the louver. Thereby, an accent is given to the center part of the louver 14 by the decorative surface 18e of the connecting member 18-1, and the design can be improved.

It is a front view showing the vertical blind concerning the embodiment of the present invention. It is a figure showing one louver. It is a disassembled perspective view of one louver.
