[Industrial applications]

 The present invention relates to a panel shutter that opens and closes a building opening by a shutter formed by vertically connecting and suspending a plurality of panels.

[0002]

[Prior Art]

 In general, a panel shutter device forms a shutter by connecting and suspending a supporting shaft, which is rotatably supported on both ends of a plurality of panels, by a roller chain in series to form a shutter and raises and lowers the shutter along a guide rail. In order to transfer from the movement to the lateral movement along the storage rail in the front-rear direction, a guide sprocket that meshes with the roller chain is pivotally installed above the upper end of the guide rail, and the shutter is hoisted and suspended by forward and reverse rotation of the guide sprocket. When the shutter is suspended, the running rollers pivotally supported by the tip of the support shaft of each panel are guided by the guide rails standing upright in the opening, so that each panel is placed in a vertical plane. When closing the shutter, the panels are sequentially fed into the storage rails provided in the front-back direction above the opening. To open the opening, and each panel on storage rail by the rotation of the driving roller is accommodated in hanging parallel form.

However, in the above structure, when the panels are sequentially fed into the storage rails provided in the front-rear direction above the opening when the opening is opened, the panels are hung only on both sides of the upper end. Each of the panels is transformed into a parallel state and moved to the rear of the storage rail, so that the panels that are in a parallel position can be swung in the anteroposterior direction while the panels collide with each other. Not only becomes a source of noise, but also an unnecessary impact force due to collision is applied to the panel, which induces unnatural feeding etc. and hinders conversion movement in the horizontal or vertical direction. Not only is it impossible to perform parallel movement of the panel, but the traveling roller attached to the roller chain is also used as a guide roller for the panel when moving up and down. Separately, it is necessary to form a guide groove for guiding the traveling roller in the guide rail, which has a drawback that the structure of the guide rail becomes complicated.

[0004]

[Problems to be solved by the present invention]

 The present invention has been made in view of the above circumstances in order to solve the conventional drawbacks, and the purpose thereof is to prevent each panel from moving horizontally without causing collision between the panels. The parallel movement can be performed quickly, the panel shutter can be smoothly opened and closed, and the guide rail structure can be simplified, thereby improving the reliability of the panel shutter up and down operation. The purpose is to provide a panel shutter device that can be used.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the technical means adopted by the present invention is to suspend a plurality of panels in the vertical direction via a roller chain and to move the panels in the front-back direction from the ascending / descending movement along the guide rail. In a panel shutter device in which a guide sprocket that meshes with a roller chain is pivotally installed above the upper end of the guide rail in order to transfer it laterally along the storage rail, the panel plates are attached to both ends of each panel. It is characterized in that a plurality of roller rings whose outer peripheral surfaces project in the thickness direction are attached.

[0006]

[Action]

 Therefore, according to the present invention, each panel can be quickly moved in parallel during horizontal movement without collision between the panels, and smooth opening and closing operation of the panel shutter can be performed. The structure of the guide rail can be simplified, and thus the reliability of the lifting operation of the panel shutter can be improved.
