The support members 8 and 9 are provided with an insertion hole 12 at the bottom at an inner position of the mounting portion 10, and are inserted through a slit 13 cut into the side wall corresponding to the opening side of the groove 7. communicates with the outside. Reference numeral 14 denotes a guide roller disposed between both side walls of the supporting members 8 and 9.

Reference numeral 15 denotes a pair of bifurcated bearings projecting upward from both ends of the support members 8 and 9; 16 denotes a through hole provided at both ends below the bearings 15; It communicates with the outside through a slit 17 cut in the .

A pair of support parts 18 protrudes from the right end (in FIG. 1) of one of the support members 8, and a guide roller 19 is rotatably supported between the two support parts 18.

Reference numerals 20 and 21 indicate support shafts for adjusting the tilting of the ladder cord L, which are rotatably supported between the bearing portions 15 of the support members 8 and 9, and both are fixed through the drive shaft 22 at both ends thereof. ing. Metal sleeves 20a, 21a are wrapped around the support shaft 20.21, and a large number of slats (
The upper end of the ladder cord L supporting the ladder cord (not shown) is engaged.

Note that this ladder cord L is inserted into the slit 1 of the side wall of the support members 8 and 9 when supporting the support shaft 20.21 on the bearing part 15.
3 into the insertion hole 12.

23 is a drum integrally formed in the center of one of the support shafts 20, and as shown in FIG.
The center portion of the head box 4 is fixed by being wrapped around it, and both ends thereof are suspended below the head box 3 through the insertion hole 12 of the support member 8.

By pulling either end of the adjustment string 24, the drum 23 is rotated clockwise or counterclockwise, and the inclination angle of the slat (not shown) can be adjusted via the ladder cord L.

The support members 8 and 9, the support shafts 20 and 21, and the drive shaft 22 constitute a slat angle adjustment device M.

Reference numeral 25 denotes a pair of elevating strings for elevating the slats S (not shown), one end of which is suspended below the head box 3 via a elevating string locking device (not shown) provided at one end of the head box 3. The other end of one lifting member 25 is located below the guide roller 19 of the support member 8, and the through hole 16. The guide roller 14 is suspended downward from the head box 3 through the insertion hole 12, passes through each slat (not shown), and is connected to one end of a bollard/mole rail (not shown). The other end of the other lifting cord 25 is suspended downward from the head box 3 through the guide roller 14 of the support member 9 and the insertion hole 12, passes through each slat (not shown), and connects to the bottom rail (not shown). ) is connected to the other end.

The assembly of the head box 3 and the slat angle adjustment device M configured as described above will be explained.

Each slab 1 to (not shown) is assembled to a lifting cord 25 and a ladder cord L, one end of which is attached to a bottom rail (not shown) in advance, and a support shaft 20 in which the upper ends of the ladder cord L are arranged at both ends of the drive shaft 22. .21 sleeve 20
a, 21a.

The upper part of the ladder cord L attached to this support shaft 20.21 and the lifting cord 25 at the corresponding position are inserted into the slit 13.
It is inserted into the insertion hole 12 of the support members 8 and 9 through.

Then, the lifting cord 25 on the support member 9 side is inserted into the respective through holes 16 through the sleeve l-17 on the right end side of the support member 9 (see FIG. 1) and the slits 17 on both ends of the support member 8, and 8 below the guide roller 19.

Further, the lifting cord 25 on the supporting member 8 side is inserted through the through hole 16 through the slit 17 (see FIG. 1) on the right end side of the supporting member 8, and is caused to slide below the guide roller 19 of the supporting member 8.

As mentioned above, the lifting cord 25 is connected to the through hole 1 of each support member 8, 9.
6, the support shafts 20, 21 at both ends of the drive shaft 22 are engaged with the bearings 15 at both ends of the support members 8, 9 from above, respectively (see FIGS. 3 and 6).

Thereafter, the adjustment string 24 wound around the drum 23 is inserted through the insertion hole 12 and hangs down below the support section 1 (see FIG. 3). Thereafter, the engagement grooves 11 of the respective support members 8 and 9 are pushed into the mounting groove 7 of the support section 1 from the opening side thereof in the width direction of the support section 1 to engage with the bottom wall 1a. At this time, each support member 8,
9 shall be installed. Then, a lift string 25 extending from the right end (in FIG. 1) of the support member 8 is suspended below the support frame 1 via a lift string locking device (not shown).

Then, fit the fitting groove 2a and the fitting groove 5a of the lid member 2 into the fitting protrusion 6 and the fitting protrusion 4 of the support member 1 from one end side, respectively (see Figs. 8 and 6). ).

In the head box 3 as described above, the mounting groove 7 is cut in the bottom wall 1a of the support member 1 from the open side, so that the support member 8 of the slat angle adjustment device M,
9 can be easily attached with one touch by simply inserting the support member 9 in the width direction of the support member 1 through the opening. After the lid member 2 is fitted to the support member 1 from the end side, the support members 8 and 9 do not come out of the attachment groove 7 and are securely attached.

Next, another example will be explained with reference to FIGS. 8 to 11.

In this other example, as shown in FIG.
The difference from the previous embodiment is that a pair of locking protrusions 30 are bent inward in an L-shape so as to face each other, and support grooves 31 are provided on the upper surface of both sides of the top plate 1b. There is.

Since this head box 3 is provided with the support groove 31 as described above, it can be attached to the window upper part 33 using a mounting bracket 32 as shown in FIGS. 10 and 11, for example.

This mounting bracket 32 has a base end screwed into the upper part 33 of the window.
4, and a locking piece 35 is formed at the bottom of both sides of the base end of the head box 3 and protrudes outward in a cross-sectional shape, and is engaged in the support groove 31 of the head box 3. At this time, it can be engaged with and detached from the lower surface of the locking protrusion 30 by rotating 90 degrees clockwise or counterclockwise. A lever 36 extending obliquely is formed at the tip of the floor plan fitting 32.

To attach this head box 3 to the window upper part 33,
As shown by the chain line in the figure, attach the mounting bracket 32 to the window upper part 3 in advance.
3, the screws 34 are attached so that the locking pieces 35 face in the longitudinal direction of the intended mounting position.

Then, the head box 3 to which the support section 1 and the lid section 2 are assembled is aligned with the intended mounting position, and the base end of the mounting bracket 32 is inserted into the support groove 31.

Thereafter, the mounting bracket 32 is rotated 90 degrees clockwise (in FIG. 8) by the lever 36 to the solid line position in FIG.
Bring it into contact with the bottom surface. In this way, the head box 3 is attached to the window upper part 33 (see FIG. 9).

The effects of this embodiment are similar to those of the previous embodiment.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but the fitting protrusions 4 and 6 of both shapes 1 and 2 are changed to fitting grooves, and the corresponding fitting grooves 5a and 2a are changed to fitting protrusions. It is also possible to make arbitrary changes without departing from the spirit of the invention.

Effects As detailed above, in this invention, a mounting groove is cut into the bottom wall of a support member having a cross-sectional opening shape with one side open, and a mounting groove is formed from the open side. The slats are housed in the head box by fitting flat plate-like lid members to each other in correspondence with the open sides of the support members so as to accommodate supporting members such as slat angle adjustment devices that are attached to the head box. Assembling the angle adjustment device is an excellent invention that can be easily carried out and has excellent industrial applications.
