BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

A first embodiment will be described with reference to FIGS. 1 to 3, the same parts as those shown in FIGS. 12 and 13 are designated by the same reference numerals.

A shutter box 3 is provided along an upper lintel portion (not shown) of the opening 1, and a shutter curtain 6 is housed in the shutter box 3. Guide rails 2 are provided on both sides of the opening 1 from the shutter box 3 to the floor surface 16, and the shutter curtain 6 moves up and down along the guide rails 2.

Inside each of the guide rails 2, auxiliary columns 17, 17 are provided as an auxiliary member facing the surface having the guide rail groove 18 and in parallel with the guide rail 2. Further, the auxiliary support column 17 is provided over the floor surface 16 and the lintel (not shown) and is provided over the entire length of the opening. A required gap is provided between the auxiliary column 17 and the guide rail 2, and is provided on the outdoor side and the indoor side with the shutter curtain 6 interposed therebetween. The distance between the auxiliary columns 17 on the outdoor side and the indoor side is preferably the same as or substantially the same as the width of the guide rail groove 18 of the guide rail 2, and the gap g between the auxiliary column 17 and the guide rail 2
Is smaller than a value at which the tip of the burl 14 is not inserted into the guide rail groove 18 or only a very limited portion of the tip can be inserted, as will be described later. Of course, the gap may be zero.

It should be noted that the auxiliary column 17 prevents the shutter curtain 6 from coming off further even when the shutter curtain 6 comes off from the guide rail 2, and flips off the detached part of the shutter curtain 6 to move in and out from the side. Therefore, the distance between the auxiliary columns 17, 17 may be equal to or larger than the width of the seat plate of the shutter curtain 6. In this case, it is not necessary to process the seat plate so as not to interfere with the auxiliary column 17.

The operation will be described below with reference to FIG.

First, the guide rail 2 and the auxiliary column 17
The case where the burl 14 is inserted into the gap g between them will be described.

If the gap g is small, as shown in FIG. 3, the angle of the tip of the burl 14 with respect to the guide rail groove 18 is difficult to be made, and the tip of the burl 14 is also guided by the guide rail groove 18.
Only a small part can be inserted. In this state, even if the burl 14 is rotated clockwise and the guide rail 2 is twisted, the force acting in the direction of expanding the guide rail groove 18 is small, and most of the guide rail 2
Acts as a horizontal force on. The guide rail 2 is attached to a strength member of a building such as a side pillar adjacent to the opening 1, and the drag force against the external force in the horizontal direction is far greater than the drag force against the force for expanding the guide rail groove 18. large.

Therefore, the shutter curtain 6 cannot be easily removed from the guide rail 2. Further, the force acting on the tip of the burl 14 is generated by using the auxiliary column 17 as a fulcrum of the lever. The rigidity of the auxiliary column 17 is such that it is neither easily deformed nor destroyed by the burl 14.

Alternatively, the rigidity of the auxiliary support column 17 may not be so large and the auxiliary support column 17 may have such a strength that it is not destroyed. On the contrary, the rigidity is small and the burl 14
It may be bent within a range of elastic deformation against a large external force due to the above.

As described above, the auxiliary column 17 serves as a fulcrum of the lever of the burl 14, but the bending of the auxiliary column 17 does not generate a force at the tip of the burl 14 due to the lever action. If the burl 14 is pulled out, the auxiliary column 17
Since it is restored to its original state, the burl 14 cannot be inserted deep into the guide rail groove 18.

Therefore, it is impossible to break the guide rail 2 by providing the auxiliary column 17.
Or it becomes difficult to destroy.

Next, when the burl 14 is inserted between the auxiliary column 17 and the shutter curtain 6 (2 in FIG. 3).
Will be described).

The auxiliary column 17 becomes an obstacle when the burl 14 is inserted into the guide rail groove 18, and the tip of the burl 14 does not reach the guide rail groove 18. Therefore, even when an external force is applied by the burl 14, the guide rail 2 is not deformed, and the guide rail 2 is not broken by the burl 14.

Further, the auxiliary column 17 is attached to the burl 14
It should have sufficient rigidity and strength against vandalism due to, for example, or be appropriately in the elastic displacement within the auxiliary column 17
So that it bends. In the elastic range, when it is adapted to flexibly respond to the displacement applied by the burl 14,
The auxiliary column 17 cannot be broken by the burl 14.

By eliminating the gap g, the guide rail 2
If the auxiliary strut 17 and the auxiliary strut 17 are provided in contact with each other, the burl 14 cannot be inserted between the guide rail 2 and the auxiliary strut 17, and the crime prevention effect is further increased.

Although the auxiliary column 17 does not have an absolute resistance to destruction, the time until destruction is greatly extended. Generally, it is sufficiently effective if a security alarm or the like is activated and an intrusion delay of about several minutes is reached until a guard or a police officer arrives at the scene.

Since the shutter curtain 6 is removed from the guide rail 2 from the lower end, and the shutter curtain 6 is often rolled up and intruded, the auxiliary column 1
7 is effective even if it is not provided in the entire vertical length of the opening 1 as long as it is provided up to the required height below the shutter curtain 6. Particularly, the locking device 8 in which the shutter curtain 6 is mechanically connected to the guide rail 2 is provided. Near the position (see FIG. 12), for example, a height of 1 to 2 m, and more preferably above the position of the locking device 8. In addition, the auxiliary column 17 on the indoor side
Can be omitted.

By pulling a pin or the like through the lower end of the exposed portion of the, the pulled-out state is maintained.

The post 26 has a strength greater than that of the auxiliary column 23, and is designed so as not to be damaged even when an external force larger than human power, for example, an automobile collides.

In the present embodiment, since the auxiliary column 23 has sufficient strength and is in contact with the guide rail 2, even if the guide rail 2 is deformed by the burls 14, Deformation of the guide rail 2 is suppressed by the auxiliary column 23, and it becomes difficult to break the shutter device.

Further, since the post 26 is erected at the center on the indoor side, even if the shutter curtain 6 collides with the shutter curtain 6 in an automobile or the like, the shutter curtain 6 is largely deformed and cannot be disengaged from the guide rail 2. In addition, it is difficult to break the shutter device and enter it.

The number of the posts 26 may be increased or decreased according to the width of the opening, and the position where the post 26 is provided is arbitrary with respect to the width of the opening, but it is preferably a position where the opening width is equally divided. Is good.
