DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to FIGS. 1 (A) and 1 (B) are perspective views showing a lower middle column and a lower middle column fixing device, respectively, and FIG. 2 is a sectional view showing a mounting structure of the fixing device. FIG. 3A is a view of the lower fixing device for the middle pillar of this embodiment viewed from the indoor side.
FIG. 4B is a perspective view showing the receiving device, FIG. 4A is a diagram of the lower device for fixing the lower center column of the present embodiment as viewed from the indoor side with the center column fixed to the receiving device, and FIG. It is a disassembled perspective view which shows the falling prevention structure of a drop bar.

The apparatus shown in FIGS. 1 to 4 is provided for a shutter having the same basic structure as the shutter shown in FIG. 5, and a reference numeral 25 denotes a center pillar shown in FIG. 24 is removably interposed therebetween. It has a guide groove 25a on the left and right sides of the center pillar 25,
Both ends of the slat 21 are vertically movably fitted into the groove 25a and the groove of the guide rail 22 shown in FIG.

1 to 4, reference numeral 1 denotes a drop bar holder, 2 denotes a drop bar, 3 denotes a retaining bar, and 4 denotes a holder.
As shown in FIG. 1, the drop bar 2 is formed by bending a bar-shaped steel material into a substantially inverted U-shape, and has a grip portion 2b which is bent obliquely toward the indoor side above the right and left straight bar portions 2a. And has a retaining projection 2c at the lower end.

The drop bar holder 1 comprises a first plate member 5 and a second member 6. The second member 6 has a U-shaped drop bar holding portion 6 for holding the right and left straight bar portions 2a of the drop bar 2.
a straight rod portion 2a of the drop bar 2 in the drop bar holding portion 6a.
Is fixed to the first member 5 by the fixing tool 7 or the like.

The drop bar holding portion 6a of the second plate member 6
The supporting portion 6b of the braking member 8 is formed by removing a part in the middle, and as shown in FIG.
By fitting the braking member 8 made of an elastic material made of an annular synthetic resin having the shape described above, and press-fitting the straight rod portion 2a of the drop bar 2 from the cutout portion 8a, the drop of the drop bar 2 due to its own weight is prevented. That is, the opening width of the notched portion 8a is set to be slightly smaller than the inner diameter of the braking member 8, and the inner diameter of the braking member 8 is set slightly smaller than the outer diameter of the drop rod 2, so that the elastic member of the synthetic resin material drops. Since the rod 2 is tightened by the braking member 8 and the braking member 8 is fitted and held in the support portion 6b, the falling rod 2 is prevented from falling by its own weight due to friction with the braking member 8. The vertical movement range of the braking member 8 itself is limited by the support portion 6b of the drop bar holder 1.

Although the drop bar holder 1 may be constructed as an integral type, according to the present embodiment, the first and second drop bars are provided.
By processing the plate materials 5 and 6 into the above-described structure, and sandwiching the straight bar portion 2a of the drop bar 2 between them,
A structure having a retaining projection 2c at the lower end can be manufactured in advance, which facilitates assembly.

The retaining bar 3 is held between the holding plate 9 and the second plate 6 shown in FIG.
An engaging portion 3 bent substantially horizontally at the lower end of the retaining bar 3
a, and has an operating portion 3b bent at the upper end.

The holding plate 9 has a holding portion 9a having a U-shaped cross section for holding the retaining bar 3 in a vertically movable manner.
Of the brake member 8 is formed by removing a part in the middle of the support member 9, and the brake member 8 having the same shape as that described above is attached to the support portion 9 b.
b and the stopper bar 3.

The retaining bar 3 has a locking portion 3a which is bent substantially horizontally at the lower end, and which is substantially horizontal and has a different bending direction when viewed from above (preferably approximately 40).
(About 50 degrees) The operation unit 3b is formed so as to be different.

As shown in FIG. 3 (B), the straight rods 2a of the drop rods 2 are inserted into the receiving members 4 fixed to the floor, respectively, to prevent the front, rear, left and right movements of the center pillar 25. Lock hole 4a
Between the locking holes 4a, 4a.
And a locking portion 4b composed of a long hole for locking the locking portion 3a by inserting the locking portion 3a and turning the retaining bar 3. A receiving piece 9c is provided on the upper portion of the holding plate 9 for locking the operation portion 3b when the retaining bar 3 is raised.
And a receiving portion 9d formed in a notch shape in the receiving piece 9c and fitted with the operating portion 3b by rotating the operating portion 3b with the retaining bar 3 lowered.

The mounting of the lower fixing device for the lower part of the center column of this embodiment to the center column 25 is as shown in FIG.
In a factory, holes 18 and 19 provided on the left and right of an intermediate portion between the first and second plate members 5 and 6 and a hole 25 provided on a center pillar 25 are provided.
c, and the rivet 10 is inserted into the hole 15b of the back plate 15 housed in the middle pillar 25 and caulked, thereby being fixed to the lower part of the middle pillar 25. Further, insertion holes 13, 16, in which the screws 12 are provided at the corresponding positions of the holding plate 9 and the first and second plate members 5, 6,
17 and through the hole 25b of the center post 25
By screwing into the screw hole 15a of the back plate 15 provided in the inside 5, the holding plate 9 is detachably fixed to the center pillar 25 together with the drop bar holder 1. In this case, the rivet 10
Is housed in the recess 9 e of the holding plate 9.

In a usage mode in which the holding plate 9 and the retaining bar 3 are not attached, the screw 12 is inserted into the holes 16 and 17 provided at the corresponding positions of the first and second plate members 5 and 6, and the screw 12 is inserted in the middle. By being screwed into the screw hole 15a of the back plate 15 provided in the middle post 25 through the hole 25b of the post 25, the detachable rod holder 1 and the drop bar holder 1 are detachably fixed to the middle post 25. That is, the holding plate 9 and the retaining bar 3 can be optionally attached according to the user's request, and a structure without the retaining plate 9 and the retaining bar 3 can be used. It is configured so that it can be retrofitted.

When fixing the center column 25 using the fixing device for the center column, the lower portion of the center column 25 is placed on the holder 4 and the drop bar 2 is pushed down as shown in FIG. Thereby, the drop bar 2 is inserted into the locking hole 4a. At the time of strong wind, by operating the operation part 3b of the retaining rod 3, the direction of the locking part 3a is matched with the direction of the locked part 4b of the receiving member 4,
By pushing down the operation section 3b through the side of the receiving piece 9c and then turning the operation section 3b toward the receiving section 9d, FIG.
As shown in FIG. 3A, the locking portion 3a of the retaining rod 3 is locked by sliding the locking portion 3a under the top plate 4c of the receiving member 4.

As described above, by locking the locking portion 3a to the locked portion 4b, even if the middle pillar 25 is bent by the strong wind, the drop bar 2 can be locked in the locking hole of the receiving member 4. There is no escape from 4a.

In the present invention, the braking member 8 made of an elastic material is used.
As a material of the resin, not only synthetic resin and rubber but also stainless steel which is a metal can be used, and a thin plate formed in a ring shape like a drum can be used. In addition, the present invention is not limited to the above embodiment, and various changes and additions can be made to the drop bar holder 1, the drop bar 2, the retaining bar 3, the receiving member 4, and the like.

[0026]

[0027]

According to the present invention , the braking member of the drop bar is
Since the elastic member is attached to the drop bar, the structure is simple and easy to attach, and the braking member is inexpensive.
