  FIG. 1 is a front view of a blind according to an embodiment of the present invention. The blind 10 is set to an opening such as a window frame, and includes four blind units 12 (12A, 12B, 12C, and 12D) that are connected to each other vertically and horizontally. The blind units 12A and 12B are arranged at the upper part, and the blind units 12C and 12D are arranged at the lower part.

  Each blind unit 12 according to this embodiment is a horizontal blind unit, each of which includes a head box 14 as an upper support member, a ladder cord 16 suspended from the head box 14, and a plurality of pieces supported in alignment by the ladder cord 16. The slat 18 is provided. Preferably, as shown in the enlarged partial sectional view of FIG. 2, a notch 18a for inserting the ladder cord is formed at an edge portion of the slat 18 adjacent to the ladder cord 16, and this notch portion is formed on the ladder. By passing the cord 16, the lateral displacement of the slat 18 is prevented.

  The head box 14 of the blind unit 12A and the blind unit 12B located on the upper side is connected to the upper support rail 20 along with each other by the bracket 13, and the head box 14 of the blind unit 12C and the blind unit 12D located on the lower side is connected to the bracket 13 Are connected to the lower support rail 22 side by side. Further, the lower ends of the blind units 12 </ b> A and 12 </ b> B located at the upper part are connected to the lower support rail 22.

  More specifically, the lower ends of the ladder cords 16 of the upper blind units 12A and 12B are introduced into the lower support rail 22, where they are fixed to the lower support rail 22 as shown in FIG. It circulates around a rotating shaft 22a extending inside. Therefore, the lower support rail 22 is held at the upper and lower intermediate positions of the blind 10 by the ladder cord 16 of the blind units 12A and 12B located at the upper portion, and the movement of the ladder cord 16 is not transmitted to the lower support rail 22. ing. However, a spacer cord is provided between the upper support rail 20 or the head box 14 of the blind unit 12A, 12B located at the upper portion and the lower support rail 22, and the lower support rail 22 is placed in the middle of the blind 10 by the spacer cord. It is also possible to hold it in position.

  As described above, the four blind units 12A, 12B, 12C, and 12D are connected to each other vertically and horizontally. The lower ends of the ladder cords 16 of the blind units 12C and 12D located at the lower part are connected to the lowermost rail 26.

  The upper end of the ladder cord 16 of each blind unit 12 is introduced into the head box 14 and connected to tilt drums 30 and 30 disposed in the head box 14 as shown in FIG. The tilt drum 30 is connected to a shaft 32 that is supported in the head box 14. An output gear of the gear mechanism 36 is engaged with one end portion of the shaft 32, and the input gear of the gear mechanism 36 is connected to a dial 34 as an operation unit disposed on the front surface of the head box 14. When the dial 34 is rotated, the rotation is transmitted to the shaft 32 via the gear mechanism 36, and the shaft 32 rotates, so that a relative movement of the front and rear vertical cords of the ladder cord 16 occurs. Rotates.

  In the blind 10 configured as described above, one of the left / right / upper / lower blind units 12 (12A, 12B, 12C, 12D) is selected, and its dial 34 is operated, When the slat 18 of the blind unit 12 is leveled, light can be taken in locally from the portion of the blind unit 12 or a view can be obtained. For example, as shown in FIG. 1, only the slats 18 of the blind unit 12A and the blind unit 12D are horizontal, and thus any local portion of the opening in which the blind 10 is set can be opened and closed. .

  In the above embodiment, the head boxes 14 of the lower blind units 12C and 12D are attached to the common lower support rail 22. However, separate head support rails 22 or lower support rails 22 may be used. It is possible to omit and connect the head boxes 14 and 14 of the lower blind units 12C and 12D directly to the upper blind units 12A and 12B as lower support rails. An example is shown in FIG. In this example, the lower ends of the ladder cords 16 of the upper blind units 12A and 12B are rotated around the axes of the shafts 32 and the like in the head boxes 14 and 14 of the lower blind units 12C and 12D as shown in FIG. doing. The configuration of FIG. 5 can be similarly operated.

  Further, in the above embodiment, a total of four blind units of the same shape and the same type are used, two each on the left and right and top and bottom. However, the present invention is not limited to this, and various sizes or types are available as shown in FIG. It is also possible to combine different blinds. As the different types, the color and material of the shielding material are different, and furthermore, not only the horizontal blind unit but also one selected from a roll screen unit, a vertical blind unit, a pleated screen unit, etc. Combinations are also possible. It is also possible to prepare a plurality of types of blind units and replace them appropriately with blind units in use. Since the blind unit 12 is detachably attached to the upper support rail 20 or the lower support rail 22 by the bracket 13, the blind unit can be easily replaced. If each blind unit has a different color, the positions of the left, right, top and bottom blind units can be switched so that the color scheme can be changed according to preference.

  Further, in the examples of FIGS. 1 to 4, the open / close operation of the slats that can be operated is only the rotation operation of the slats. However, the present invention is not limited to this. it can. An example is shown in FIGS. In this example, a lifting / lowering cord 40 is suspended from the head box 14 of each blind unit 12, and the lifting / lowering cord 40 is inserted through a lifting / lowering cord insertion hole provided in each slat 18, and one end of It is connected to the bottom rail 42 arranged at the lowermost position.

  Further, the head box 14 of the lower blind unit 12C, 12D includes the head box 14 of the upper support rail 20 or the upper blind unit 12A, 12B and the lower support rail 22 or the lower blind unit 12C, 12D. A spacer cord 44 is provided between the head box 14 and the head box 14 of the blind units 12 </ b> C and 12 </ b> D located below the lower support rail 22 or the lower portion of the blind 10 by the spacer cord 44.

  The other end of the lifting / lowering cord 40 is connected to a lifting / lowering drum provided on the shaft 32 of the head box 14 so as to be wound and unwound. By rotating the dial 34 and rotating the shaft 32, the elevating drum rotates to wind or unwind the elevating cord 40, the bottom rail 42 moves up and down, and the slat 18 also moves up and down.

  Therefore, by selectively raising the slat of a certain blind unit, the part can be completely opened. In this way, any local portion can be opened and closed.

  In addition, one end of the lifting / lowering cord is not connected to the bottom rail of each blind unit, but is connected to the lower support rail and the lowermost rail 26, so that not only the blind unit slat but also the entire blind or multiple blind unit slats. It is also possible to move up and down all together.

  Furthermore, although the dial was used as an operation part for opening and closing the slats of each blind unit, rotation can be transmitted to the gear mechanism, and for example, a crank type handle provided detachably can be used, In this case, it is possible to open and close the slats of each blind unit by operating the handle as the operation portion even if the upper support member of the blind unit is at a level that is out of reach.

  Thus, various variations can be given to one blind, and the user can enjoy the change by appropriately selecting one of the variations according to the preference or the atmosphere.
