BACKGROUND OF THE INVENTION Generally,
Inside this kind of large opening, a cargo handling ceiling rail for transporting luggage inside and outside the building is laid, and a cargo handling crane and hoist are movably installed here to enable indoor and outdoor cargo handling work. The architectural shutter is also installed in such an opening. By the way, in this case, the shutter curtain needs to be opened and closed at an inner position avoiding the cargo handling ceiling rail so as not to interfere with the cargo handling ceiling rail that extends indoors and outdoors. Then, the guide rails for the shutter curtains also need to be provided inside the ceiling rails for cargo handling. However, if it is left as it is, the guide rail interferes with the cargo handling work. Therefore, it is necessary to move the guide rail outside the ceiling rail for cargo handling so as not to interfere with the cargo handling work. However, if such an attempt is made, the portion of the guide rail corresponding to the cargo handling ceiling rail hits the cargo handling ceiling rail and cannot be moved outward so that the guide rail cannot be stored.
Inevitably, the parts corresponding to the ceiling rail for loading and unloading should be cut out.If this happens, the guide rail will be missing this notched part, and the shutter curtains will not be opened or closed in this incomplete guide state. The problem of having to do this arises, and it is required to solve this.

The cargo handling ceiling rail 8 is laid both indoors and outdoors at the left and right ceiling positions of the opening, and moves indoors and outdoors. It has a structure that allows cargo handling work.

The guide rail main body 3 has a substantially U-shaped cross section, but the opening edge portion thereof is narrowly opened by a pair of inner and outer guide sides 3a to guide the opening and closing of the shutter curtain 1. The rail body 3 is hinged to the body side by a hinge 3b so as to be rotatable, and a guide position for guiding the shutter curtain 1 as described later and a ceiling rail 8 for cargo handling so as not to interfere with cargo handling work.
It can be rotated to a retracted position retracted to the outside. Incidentally, the rotation of the guide rail main body 3 is
It goes without saying that either automatic operation using an appropriate driving means such as a motor or manual operation by an operator may be used. Moreover, the upper end portion of the guide rail main body 3 has the cargo handling ceiling rail 8 when it is in the guide position.
A notch 3c is formed in a substantially L shape so as not to interfere with the above. When the shutter curtain 1 described later is closed, the cargo handling ceiling rail 8 penetrates through the notch 3c to the inside and the outside. Is set. Needless to say, the guide rail main body 3 may be a moving system that slides in the left-right direction instead of the rotating system.

On the other hand, the ceiling guide rail 2 is provided at an inner portion corresponding to the cargo handling ceiling rail 8, and its base end (upper end) is the shutter case 7.
Is pivotally supported by a mounting bracket 9 provided on the side through a support shaft 9a and vertically extends from the shutter case 7 side to guide the shutter curtain 1 at an inner portion corresponding to the cargo handling ceiling rail 8. Guide posture and Magsa 6
It is possible to swing and transform into a storage posture in which it is stored horizontally. Here, the ceiling guide rail 2 includes front and rear side 2a pivotally supported by the support shaft 9a and the guide side 3a.
Is integrally formed with a guide side 2b corresponding to the above and a connecting side 2c for connecting the upper end portions of the front and rear side 2a at the groove bottom position, and the tip side portion of the connecting side 2c penetrates in the left-right direction. It becomes a part 2d, and in this penetrating part 2d,
A substantially inverted T-shaped seat plate 1a at the lowermost end of the shutter curtain 1 is loosely fitted. Front and rear sides 2
Although a pair of first and second rollers 10 and 11 is provided in a, the lower first roller 10 is located inward below the support shaft 9a in the guide posture of the ceiling guide rail 2. The upper second roller 11 is set so as to be positioned substantially below the support shaft 9a.

In the process of opening the shutter curtain 1, the lower plate portion 1b of the seat plate 1a tries to lift the ceiling guide rail 2 by hitting the lower first roller 10 from the lower side. Is located inward of the support shaft 9a, the ceiling guide rail 2 is lifted so that its tip faces inward, and the left and right ends of the seat plate 1a are penetrated by the penetrating portion 2
It will rotate while penetrating d. Then, after this lifting rotation progresses and the second roller 11 is at the same height as the first roller 10, the seat plate lower plate portion 1b hits the second roller 11 from the lower side and is similarly lifted and rotated. When the shutter curtain 1 is fully opened, the ceiling guide rail 2 is housed in the shutter case 7 in a substantially horizontal posture parallel to the magsa 6. On the other hand, when the shutter curtain 1 is closed, the ceiling guide rail 2 moves in the opposite direction to the above-described opening motion.
Although details thereof will be omitted, the front and rear sides 2a extend below the guide sides 2b, and when they are in a guide posture, they are loosely fitted to the front and rear sides 3d of the guide rail main body 3 in a laminated manner, and The left and right outer edges of the extended portion of the front and rear side 2a come into contact with a stopper 12 integrally provided on the outer surface of the front and rear side 3d of the guide rail main body 3 and swing further outward in the left and right direction. Are being regulated.

A positioning pin 13 is provided on the guide rail main body 3 so as to be capable of projecting and retracting in the vertical direction, and an operating tool (not shown) installed inside the operation box 14 with the guide rail main body 3 set in the guide position. When the positioning pin 13 is caused to project by the operation (1), the projecting positioning pin 13 is fitted into the positioning holes 8a and 15 formed on the lower surface and floor surface of the cargo handling ceiling rail 8 to be positioned and held. It is set. Further, a detection switch 16 for detecting that the guide rail main body 3 is set at the guide position is provided on the upper surface of the cargo handling ceiling rail 8, and the cargo handling crane is provided only when there is no detection of the detection switch 16. The cargo handling work (not shown) can be performed, and the shutter curtain 1 can be opened and closed only when a detection is made.

The ceiling guide rail 2 is received and supported by the stopper 12 while being loosely fitted to the ceiling guide rail 2. Therefore, the ceiling guide rail 2 is guided in both front and rear directions and left and right outer directions. The rail main body 3 is supported (the left and right sides are supported by the shutter curtain) for accurate positioning and setting, and the set state is maintained and does not shake carelessly. The guide function of the shutter curtain 1 can be further improved.

[0013]

In summary, since the present invention is constructed as described above, a guide rail for a shutter curtain that opens and closes an opening in which a ceiling rail for cargo handling is provided indoors and outdoors is used as a guide rail for cargo handling. The shutter curtain is composed of the guide rail main body provided below the ceiling rail and the ceiling guide rail provided inside the cargo handling ceiling rail, so that the shutter curtain has no omission in the portion corresponding to the cargo handling ceiling rail. In this state, the opening / closing guide is smoothly performed on all opening / closing paths from the magsa position to the floor surface.

On the other hand, in the cargo handling work, by moving the guide rail main body to the retracted position and moving the ceiling guide rail to the storage posture, the guide rail main body and the ceiling guide rail move along the cargo handling ceiling rail. However, in this case, the ceiling guide rail at a high place can automatically change the storage posture-guide posture by effectively using the opening and closing of the shutter curtain. Therefore, it is not necessary to work at high places to transform the ceiling guide rail.
