2. Description of the Related Art In general, a venetian blind head box has a ladder tape which supports a plurality of horizontally placed slats so that each slat keeps a predetermined interval vertically and downwards from a plurality of positions of the head box. In order to make this group of slats spread (rolled down) from the window surface to the folded up (rolled up) state, the lifting cord is hung from two positions on the headbox and the lower end of the slat group is dropped. In addition to this, the upper end of the ladder tape is connected to a rotating shaft in a head box so that the light-shielding state can be adjusted by rotating the slats. The upper end of the lifting cord extends from the end through the head box to the outside of the box, and the bottom rail is pulled by pulling the extended cord end. It has a structure to be later.

As described above, the head box of the Venetian blind has a structural feature in which an operation mechanism for supporting and folding the slat group and an operation mechanism for adjusting the light blocking state are housed inside.

On the other hand, as shown in FIG. 3, a pleated screen known as a kind of blind is provided with an upper end piece 101a of a sheet 101 made of cloth or paper folded in a bellows shape at the bottom of a head box 102. The lower end piece is fixed to a bottom rail (both not shown), and is further stopped by a lifting cord (not shown) suspended from the head box 101. The lower end is connected to the bottom rail, and the screen 101 is unfolded and folded up on the window surface by winding and unwinding. A shaft is provided, and the rotating shaft is configured to be rotated by an operation cord attached to an end of the head box. There are features.

[Problems to be Solved by the Invention] By the way, for blind manufacturers, distributors, etc., if parts can be shared between blinds with different specifications, rationalization of parts inventory, reduction of storage facilities, unification of design specifications There is an advantage in that wasteful costs can be reduced by the use of a screen, and there is an advantage that a low-priced product can be quickly provided. The pleated screen of the above-described two types of blinds is capable of winding up and down the lifting cord. Although the specific structure of the mechanism is not the same as that of the Venetian blind, it has a common arrangement in that the operating mechanism is housed in the head box.

Therefore, the inventor of the present invention has concluded that, as described above, the Venetian blind using a large number of slats and the pleated screen using a single sheet differ in the overall appearance and the configuration of the components used. Focusing on the fact that it has a common property in terms of the function of the operation mechanism that folds and unfolds the slat group and screen on the window surface by winding up and down the lifting cord hanging from the head box, In the head box of the pleated screen, the storage part of the rotating shaft mechanism for winding and unwinding the elevating cord and the holding part for stopping the upper end of the pleated screen are functionally separated. We focused on the fact that it can be configured separately. In other words, they noted that although their operating mechanisms were not the same, the frame body accommodating them could be commonly used.

The inventor of the present invention sorts out these points and limits the sharing of parts between the Venetian blind and the pleated screen to the storage of the lifting / lowering cord hoisting / unwinding mechanism. Significant reduction of resources,
The present inventors have found that the cost can be significantly reduced, and propose the present invention.

Another object of the present invention is to achieve the rationalization of parts inventory management and the reduction of product cost by realizing the sharing of some parts of the above-mentioned venetian blind and pleated screen head box. is there.

The feature of the combination headbox of the present invention that achieves the above object is that the cross section is substantially concave, and the elongated headbox provided so as to be able to form the frame of the venetian blind headbox alone. A first frame member, and a long second frame formed as a flat channel-shaped frame having a cross section opened downward, and provided in the downward opening so as to house and enclose the upper end of the pleated screen. The bottom of the first frame member and the ceiling of the second frame member are detachably provided , and the first frame member alone is
Can be used as a head box of netian blinds
And a bottom of the first frame member and the second frame.
Pleated screen with a configuration in which the ceiling of the frame member is attached
In such a manner that it can be used as a head box for a vehicle.

The attachment and detachment of the first frame member and the second frame member are not particularly limited.
For example, a snap type is used only at the time of fitting, and a slide type is used at the time of removal.

The first frame member can independently constitute a head box for a Venetian blind, and a rotating shaft of a hoisting and lowering mechanism for lifting and lowering cords housed inside the first frame member. The upper end of the lifting cord is connected to the bottom frame, and the lower end connected to the bottom rail is provided so as to pass through an insertion hole provided in the second frame member attached to the bottom of the first frame member. Boxes can be configured.
