DESCRIPTION OF THE PREFERRED EMBODIMENTS In a horizontal blind shown in FIG. 1, a steel head box 1 is attached to a window frame or the like via a mounting bracket 1a. Numerous slats 3 are supported by a plurality of ladder cords 2 suspended from the head box 1, and a bottom rail 4 is suspended from the lower end of the ladder cord 2.

As shown in FIG. 5, the head box 1
A support member 5 is disposed in the inside, and an upper end of the ladder cord 2 is attached to a code drum 6 rotatably supported by the support member 5.

A square rod-shaped angle adjusting shaft 7 is fitted into the code drum 6. When the operating rod 9 suspended and supported by one end of the head box 1 is rotated, the angle adjusting shaft 7 is rotated, and the cord drum 6 is rotated with the rotation of the angle adjusting shaft 7, and the ladder One warp of the cord 2 is pulled up, and each slat 3 is rotated.

A lifting cord 8 parallel to each ladder cord 2 is inserted into each slat 3, and one end of the lifting cord 8 is connected to the bottom rail 4. The other end of the lifting cord 8 is guided toward the one end of the head box 1 via the support member 5.

The elevating cord 8 guided to one end of the head box 1 is inserted into an operating rod 9 hung at one end of the head box 1 and attached to a code equalizer 10 below the operating rod 9. Have been.

When the cord equalizer 10 is pulled downward and the lifting cord 8 is pulled out of the head box 1, the bottom rail 4 is pulled up and the lower slat 3
, The bottom rail 4 and the slat 3 are lowered by pulling the lifting cord 8 into the head box 1 based on the weight of the bottom rail 4 and the slat 3.

Each time the elevating cord 8 is pulled downward, the head box 1 is prevented from moving the elevating cord 8 in the lowering direction of the bottom rail 4 and the bottom rail 4 is made freely movable. There is provided a stopper device capable of alternately selecting a state in which 4 can be lowered.

At the ends of the steel head box 1, end caps 11a and 11b are fitted. That is, the outer shape and outer dimensions of the head box 1 are formed substantially the same as those of the aluminum head box 12 shown in FIG. 4, and the wall thickness is formed thinner than the aluminum head box 12.

Then, the end cap 11a on the operation rod 9 side
Is fitted on the outer surface of the end of the head box 1 as shown in FIGS. As shown in FIGS. 7 and 8, the end cap 11b on the opposite side of the operation rod 9 is fitted to the head box 1 so as to sandwich the end of the head box 1 from outside and inside. I have.

As shown in FIG. 4, the end cap 11a can be fitted to the outer surface of the aluminum head box 12, and the end cap 11b can be similarly fitted to the aluminum head box 12. It can be fitted to.

On the bottom surface of the head box 1, two protrusions 13 are formed in the longitudinal direction. An aluminum head box 1 is provided on the upper edge of the head box 1.
Similarly to 2, a bent portion 14 that is bent in a direction approaching each other is formed.

On the lower surface of the support member 5, a fitting portion 15 that can be fitted into a mounting hole provided on the bottom surface of the head box 1, and on both sides of the fitting portion 15, An abutting surface 16 is formed to abut.

When the fitting portion 15 is fitted into the mounting hole of the head box 1, the contact surface 16 comes into contact with the ridge 13 as shown in FIG. Then, the support member 5 is supported between the ridge 13 and the bent portion 14 of the head box 1.

That is, in the aluminum head box 12, the contact surface 16 of the support member 5 contacts the bottom surface of the head box 12, whereas in the steel head box 1, the difference in the inner size from the aluminum head box 12 is reduced. The abutment surface 16 is supported on the protruding ridge 13 that protrudes to supplement.

With the horizontal blind constructed as described above, the following effects can be obtained. (1) Since the ridge 13 is formed on the bottom surface of the steel head box 1, the support member 5, which is common to the support member mounted in the aluminum head box 12, is bent.
4 and the ridge 13 can be supported.

(2) An end cap 11 common to an end cap fitted to the aluminum head box 12 can be fitted to the end of the steel head box 1. (3) Support member 5 and end cap 11 attached to steel head box 1 and aluminum head box 12
Since a and 11b can be shared, the number of parts can be reduced and the cost of parts can be reduced.

(4) Since the end cap 11b is fitted to the head box 1 so as to sandwich the head box, even if the head box 1 is deformed, it is securely fitted. It is possible. Therefore, the head box 1 can be prevented from falling off.

The above embodiment can be modified as follows. -The protrusion 13 may be three or more. -Instead of the ridge 13, it is good also as a protruding surface provided with the area which made the contact surface 16 stably supportable. -Instead of the ridge 13, a plurality of projections may be used. The present invention is not limited to the case where the support member 5 is supported between the ridge 13 and the bent portion 14, but may be configured to support the support member between ridges provided on the inner surface of the head box. The support bracket and the upper cover of the head box fitted on the outer surface of the head box 1 can be shared irrespective of the change in the thickness of the head box 1, similarly to the end caps 11a and 11b. . In the above embodiment, the thickness was reduced without changing the outer dimensions of the head box. However, the thickness was changed without changing the inner dimensions of the head box to compensate for changes in the outer dimensions of the head box. The projection may be provided on the outer surface of the head box. In this case as well, not only the support member provided in the head box, but also the end cap, the support bracket or the upper cover of the head box fitted to the outer surface of the head box can be shared. If the support member 5 supported by the head box 1 is configured to support a take-up shaft that winds up and down a cord for a lift-up curtain or a pleated curtain, the above-described configuration is also used for a lift-up curtain or a pleated curtain. can do.

[0033]

As described above in detail, the present invention can provide a head box of a solar shading device that can use an externally-fitting end cap and a supporting member irrespective of the wall thickness.
