[0001]

[Industrial applications]

 The present invention relates to a panel shutter configured so that a panel plate can be transformed into a vertically closed position and a horizontally stored position.

[0002]

[Problems to be Solved by Prior Art and Invention]

 Generally, in this type of panel shutter, the lowermost guide roller among the upper and lower guide rollers pivotally supported on the upper and lower edges of the panel plate is installed on the vertical guide rails provided on the left and right side edges of the opening. The remaining upper guide rollers are guided by the running guide rails having vertical rails and horizontal ceiling rails so that they can be transformed into a vertical closed posture and a horizontal storage posture. There is something. However, this requires a vertical guide rail on which the lowermost guide roller travels and a traveling guide rail on which the remaining guide rollers travel, so the number of parts is inevitably increased and both guide rails are integrated. However, the assembly process is troublesome and complicated, and the double-rail structure makes the external appearance poor.

[Means for Solving the Problems]

 The present invention was devised in view of the above circumstances to provide a panel shutter capable of eliminating these drawbacks. In the panel shutter, the upper and lower guide rollers are guided by guide rails provided on the left and right side edges of the opening so that they can be transformed into a vertical closed posture and a horizontal storage posture. , The diameter of the lowermost guide roller is set to be smaller than the diameter of the other upper guide rollers, while the guide rails are oriented vertically and the roller guide width allows the upper guide rollers to roll. And a wide horizontal guide that is laterally branched from a branch formed on the upper part of the wide vertical guide so that the roller guide width is maintained in the wide state. The narrow width of the roller guide is branched vertically upward from the branching portion, and the width of the roller guide is set narrower than the diameter of the upper guide roller and narrow enough to allow the rolling of the lowermost guide roller. It is characterized by being configured with a vertical guide portion.

The present invention is configured such that it can be opened and closed by using a common guide rail.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a panel curtain shutter curtain, which comprises a plurality of panel plates 1a that are swingably hinged through hinges (not shown) and are bound in series. However, guide rollers 2 and 3 are rotatably supported on the upper and lower portions of the left and right edges of each panel plate 1a. Of these guide rollers, the lowermost guide roller 3 is set to have a smaller diameter than the remaining upper guide rollers 2. Reference numeral 4 denotes an actuating body made of an appropriately long object such as a wire, a chain, and a string, the tip of which is connected to the lower end of the lowermost panel plate 1a. The actuating body 4 is provided on the ceiling side. The winding means 5 is set so as to be wound up, but if the panel shutter is of an electric type, the winding means 5 is connected to a switch using an electric motor, and If it is a manual type, it has a built-in balance ammunition that stores energy as the actuating body 4 is unwound, but the electric and manual concrete means should be the same as before. You can

Reference numeral 6 is a guide rail embodying the present invention. The guide rail 6 includes a wide vertical guide portion 6a vertically provided on both left and right edges of the opening, and the wide vertical guide portion 6a. A wide lateral guide portion 6c that is laid laterally along the ceiling from a branch portion 6b formed at the upper end of the, and a narrow vertical guide portion 6d that is laid further vertically upward from the branch portion 6b. It is configured. That is, the wide guide portions 6a and 6c are set such that the roller guide width is a groove width that allows the upper guide roller 2 to travel and guide, but the narrow guide portion 6d is narrower than the upper guide roller 2 in diameter. Therefore, only the travel guide of the lowermost guide roller 3 is allowed. Then, when the shutter curtain 1 in the fully closed posture facing the vertical direction is opened by the winding operation of the operating body 4, the upper guide roller 2 moving upward in the wide vertical guide portion 6a is separated. When reaching the branch portion 6b, the movement to the narrow vertical guide portion 6d is restricted, and the narrow horizontal guide portion 6c is moved to the wide horizontal guide portion 6c side. On the other hand, when the lowermost guide roller 3 reaches the branching portion 6b, the lowermost guide roller 3 is moved to the narrow vertical guide rail 6d side by winding the actuating body 4 as described above. By being forcibly guided, the shutter curtain 1 is stored in a substantially horizontal storage posture along the ceiling surface with the lowermost end positioned at the opening magsa position.

In the embodiment of the present invention configured as described above, as described above, the shutter curtain 1 is placed in the vertical closing position and the horizontal storage position based on the rewinding and winding of the operating member 4. In that case, the guide rollers 2 and 3 move up and down on the left and right sides of the opening part, guided by the same wide vertical guide part 6a, and above the branch part 6b. The upper guide roller 2 travels in the wide lateral guide portion 6c, and the lowermost guide roller 3 travels in the narrow vertical guide portion 6d to open and close.

As described above, in the embodiment of the present invention, the lowermost guide roller 3 moves along the remaining upper guide roller 2 in one wide vertical guide portion 6a, which is branched. In the portion 6b, the upper guide roller 2 does not move to the wide lateral guide portion 6c side and does not move to the narrow vertical guide portion 6d, while the lowermost guide roller 3 moves to the narrow vertical guide portion 6d. And does not move to the wide lateral guide portion 6c. As a result, the guide rails 6 can be commonly used as the wide vertical guide portions 6a on both left and right sides of the opening, and a dedicated guide roller for the upper guide roller and a dedicated guide roller for the lowermost guide roller can be used as in the conventional case. Since it is not necessary to provide them separately, the number of parts can be reduced, and the work of assembling both rails is not required, which greatly improves the workability of the assembly work. Since the part exposed to the outside has a monorail structure, the appearance is not impaired. Incidentally, as shown in FIG. 5, a lower end guide 10 is provided on the lower end side of the wide vertical guide portion 6a so as to correspond to the diameter of the lowermost end guide roller 3, so that the lowermost end side panel plate 1a is fully closed. You may make it control the back-and-forth shake.

It should be noted that the present invention is not limited to the above embodiment, but in the above embodiment, the shutter curtain 1 is formed by continuously binding a plurality of panel plates 1a. The shutter curtain may be formed with only one panel plate, and the protruding positions of the guide rollers 2 and 3 from the panel plate 1a are set to be substantially the same. As in the second embodiment shown in Fig. 2, the protrusion amount of the lowermost guide roller 3 is made larger than the protrusion amount of the remaining upper guide rollers 2, while the guide rails 6 are It may be configured such that the groove width on the back side is narrow and the groove width on the front side is wide so as to be fitted individually, and in such a configuration, as in the first embodiment, the lowest end Induction of the side guide roller 3 to the narrow vertical guide portion 6d It is not always necessary to carry out the guidance by means of the actuating body 4.

[Operation effect]

 In short, since the present invention is configured as described above, the upper guide roller and the lowermost guide roller set to have a smaller diameter than the upper roller have the same wide vertical guides on the left and right sides of the opening. The upper guide roller travels in the wide lateral guide section, and the lowermost guide roller travels in the narrow vertical guide section to open / close the upper part of the branch part. become. As a result, the guide rails can be made common as wide vertical guides on both left and right sides of the opening, and as in the past, a dedicated guide for the upper guide roller and a dedicated guide roller for the lowermost guide roller are provided. Since it is not necessary to provide it separately, the number of parts can be reduced, and the work of assembling both rails is not required, which greatly improves the workability of the assembly work. The externally exposed portion has a monorail structure, so the appearance is not impaired.
