Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a rail device for door panels, in which a movable rail is provided on a fixed rail so as to be able to move toward and away from the fixed rail, and the fixed rail and the movable rail are connected in a foldable manner. This product relates to openings such as entrances and exits to which rails are attached by moving door plates such as storm shutters.

[Technical background of the invention and its problems]

Conventionally, as a shutter opening/closing device, for example, a fixed rail is attached to the top of an entrance or the like, and a movable rail that can be rotated horizontally is attached to one or both ends of the fixed rail in the length direction. There is a structure in which a plurality of door panels are foldably connected to a movable rail, each door panel is collected in a folded state, and the movable rail that suspends each door panel is horizontally rotated to separate from the fixed rail.

The above-mentioned fixed rails and movable rails are usually installed according to the conditions at the site, but in this case, installation errors often occur due to manufacturing errors in the movable rails, the condition of the building at the site, etc. In some cases, the joint between the fixed rail and the movable rail becomes poor, and there is a problem in that the transfer of the door plate wheels between the rails becomes unsmooth or impossible. In other words, the movable rail is usually a cantilever type that supports one end side in order to rotate horizontally, so when each door plate is suspended from this movable rail, the free end side will tilt downward due to the weight of each door plate. In addition, when each door plate is transferred to a fixed rail, the reaction will cause it to warp, resulting in a position shift on the free end side of the movable rail depending on the presence or absence of each door plate, and rolling wheels at the joints between the rails. This has the disadvantage that the movement of the caught rolling wheels may become unsmooth or impossible.

[Purpose of invention]

The present invention was developed in view of the above points, and when a movable rail that is rotatably supported is rotated and the tip of the movable rail is communicated with a fixed rail, the movable rail is supported from above, To maintain the continuity of the connection between the rails without being affected by the presence or absence of the door plate on the movable rail, to ensure that the transfer of the rolling wheels of each door plate is always performed smoothly, and to enable smooth opening and closing of each door plate.

[Effect of idea]

According to the present invention, a rail holder is fixed to the outer part of the fixed rail in the length direction, and a movable rail whose tip end is connected to one end of the fixed rail in a communicating state is horizontally rotated to the rail holder. Since a stopper body is provided to freely attach the movable rail and regulate the position of the movable rail from above while the movable rail is in communication with the fixed rail, the movable rail that has been set in position relative to the fixed rail can be rotated and the movable rail can be moved. At the same time, the movable rail is reliably supported by the stopper body, and the continuity of the mutual connection between the rails is maintained.
Therefore, the rolling wheels of each door plate suspended on the movable rail can be smoothly transferred to the joints between the rails and moved to the fixed rail. Furthermore, even if each door plate moves to the fixed rail and the load of each door plate on the movable rail is reduced, the movable rail is supported by the stopper body, so there is no possibility that the movable rail will warp upward due to the reaction. Since there is no contact between the rails and the continuity of the connecting parts between the rails is maintained, the transfer of the rolling wheels from the fixed rail to the movable rail is also smooth. Therefore, in a cantilever type movable rail, the continuity of the mutual connection between the rails can be maintained reliably with a simple structure without being affected by the presence or absence of a door plate for this movable rail, and the transfer of the rolling wheels of each door plate is possible. This enables smooth opening and closing of each door panel equipped with these rollers.
