BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shutter frame for protecting a lower frame of a suspended hanging shutter from rainwater and dust.

[0002]

[Problems to be Solved by the Invention] In the case of a top-hanging rain door in which a door plate is supported by an upper frame of a shutter frame and opens and closes along the rail, the rail supporting the door plate is usually covered by the upper frame, so that rainwater It is hard to be affected by dust and dust, and its penetration is small, but since the lower frame only has to play the role of restricting the movement of the door plate in the out-of-plane direction, both sides of the lower end of the door plate are sandwiched from below, and the upper side is open. Due to the shape, rainwater and dust easily enter and accumulate inside, which may hinder the running of the door plate.

Since the lower frame does not bear the load of the door plate and has no bending strength in function, there is a possibility that the lower frame may be broken by being stepped on an opening or the like where a person enters or exits, such as a terrace. The use of the shutter is limited.

The present invention has been made in view of the actual situation of a hanging shutter, and aims to propose a shutter frame having a low strength and a low possibility of infiltration of rainwater.

[0005]

In the present invention, a lower movable rail is provided below the opening to move together with the door plate, and the lower movable rail regulates the lower end of the door plate to guide the opening and closing of the door plate. Is stored in a lower guide frame fixed to the lower side of the opening to protect the lower movable rail and the rail and door wheel that guides its movement from rainwater and dust, avoiding obstacles to the running of the door plate, Further, by forming the lower guide frame into a cross-sectional shape surrounding the lower movable rail, the lower guide frame is given a bending strength, so that the shutter frame can be applied to an opening where people enter and exit.

An upper guide frame for supporting the door plate is fixed above the opening, and an upper movable rail for suspending and supporting the door plate is supported by the upper guide frame so as to be relatively movable in its length direction. The door plate opens and closes together with this upper movable rail and the lower movable rail supported in the lower guide frame fixed to the lower side of the opening so as to be relatively movable in the longitudinal direction, and the lower end of the lower plate is moved out of plane by the lower movable rail. Be bound.

The lower guide frame has a cross-sectional shape surrounding the lower movable rail, and the lower movable rail, and a door wheel and a rail for movably supporting the lower movable rail on the lower guide frame are surrounded by the lower guide frame. When the shutter is closed, it is protected against intrusion of rainwater or dust when the shutter is closed. In particular, since the lower movable rail is stored on the lower surface side of the lower guide frame, the waterproof and dustproof effect is enhanced.

The lower guide frame has a cross-sectional shape surrounding the lower movable rail, so that its cross-sectional performance, that is, resistance to load, is high. It can also be applied to departments.
