Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rain door in which all door plates are opened and closed by operating the door plates on the closed side, and the door pocket is absent.

[0002]

2. Description of the Related Art A shutter has a door closed when all doors are in use and retracted when not in use, and is normally in one of the two states, and a door alone stops at an intermediate position of opening and closing. Since it is rarely used in a state, the doorboard is only switched between the fully open state and the fully closed state, but in the conventional rain door, the doorboards are separated from each other, and the plurality of doorboards are separated from each other. Since opening and closing are performed independently for each door plate, opening and closing operations are troublesome, and especially during the storage operation after opening and the closing operation from the stored state, the door plate moves in the out-of-plane direction. It takes labor and time.

Further, when the shutter is used to store door plates, the door plates are stored on one side or both sides of the opening when they are opened, so that a door bag for storing the door plate is installed beside the opening frame. In addition to reducing the appearance and design of the shutter when it is closed, it complicates the construction work. Therefore, focusing on this point, a rain door without a door pocket is proposed in Japanese Patent Publication No. 60-35518.

This is to fix the door plate on the outdoor side, and to support the movable frame in which the door plate on the indoor side is movably accommodated on the opening frame so as to be movable in the in-plane direction, and move the door plate on the indoor side to move both door plates. The door pocket was made absent by moving it to one side of the opening frame together with the movable frame, but by fixing the door plate on the outdoor side to the movable frame, multiple door plates were stored in the movable frame in a pulling state, and Has a sliding window that can be moved to the outside of the opening frame, so the expected width of the shutter when closed is the same as that when opened.
The frame extends over the outside of the conventional shutter and expands the expected width of the shutter frame unnecessarily, sacrificing the design when opening and closing, and increasing the load applied to the movable frame. The result is an increase in the cross-sectional dimension of the material.

The present invention has been made in view of the conventional operating method of the rain door and the actual condition of the above-described structure in which the door bag is absent. The opening and closing operation of the door plate is simplified, and at the same time, the door is closed and stowed from the outer wall. This is to propose a shutter with a structure that suppresses the amount of protrusion.

[0006]

SUMMARY OF THE INVENTION In the present invention, an inclination for pushing a preceding door plate located on the opening side toward the inside of a door when moving a closing door side of a succeeding door plate to the facing abutting surface of adjacent door plates. At the same time, the adjacent door plates are pivotally supported by one of them, and the other door plates are simply moved by connecting them to each other by a connecting link that is slidably supported by the other in the length direction. The door is closed from the closed state and closed from the closed state to simplify the operation of opening and closing the door plate, and reduce the labor and labor.

An upper movable rail that suspends and supports the door plate is supported by an upper guide frame that is fixed to the upper side of the opening and guides the opening and closing of the door plate while supporting the door plate so as to be relatively movable in the length direction. When closed in the movable rail, multiple door boards are stored on the same track to reduce the expected width of the rain door when the door is closed, and when opened, the upper movable rail is extended with all door boards supported by the upper guide frame. The doorboard is located closer to the room than the extension of the upper movable rail by closing the door to the room side and stacking it up to store it, making effective use of the space beside the opening. The projected width from the outer wall in the retracted state is also reduced, improving the exterior design of the shutter when it is closed and when it is opened.

Since the front door plate is inclined toward the interior side when the subsequent door plate is moved to the open side, the facing door plates of the adjacent door plates are closed so that the open door plate moves to the fully open state. It is pushed and stored in the interior side by the door panel adjacent to the side. When all the door plates are closed, the subsequent door plates are pushed toward the open side, so that the door plates adjacent to the closed side are pushed toward the inside of the door from the preceding door plate side to the inside side, and the trailing door plates move out of the plane. After all the door plates located on the open side are stored, they move on the same orbit as when they were closed and are stored as they are.

A connecting link for connecting adjacent door plates is installed between the bottom surfaces or the upper surfaces of both door plates, one end of which is pivotally supported by one of the door plates, and the other end of which is pivotally supported by the other door plate. It is supported so that it can move in any direction. The connecting link has a movable side end that moves along the door plate on that side when the door plate is released from the closed state. It is possible to stack and store door plates adjacent to each other.

The connection link pulls the succeeding door plate from the retracted state of all the door plates to the closing side, thereby returning the door plate adjacent to the opening side from the retracted position to the track of the upper movable rail. Close it.

The leading door plate located on the open side is connected so as to be relatively movable in the prospective direction of the upper movable rail, and moves to the fully open position along with the upper movable rail along the upper guide frame by a distance corresponding to the entire width, and then the upper movable rail. While being supported by the rail, the rail is moved to the indoor side and stored. The upper movable rail moves to a position where the preceding door plate is stored, stops, and is supported by the upper guide frame in a state of protruding.

The trailing door plate located on the closing side is suspended and supported along the upper movable rail so as to be movable in the length direction thereof, and after the preceding door plate is stored, it moves along the upper movable rail on the same track as when closed. , Is stored as it is on the outside of the preceding door plate. When all doors are closed, they line up on the same track of the upper movable rail.

Since all the door plates are lined up on the same track when the rain door is closed, the closed state of the door plate is the same as that of the conventional rain door having a door bag, and the amount of protrusion from the outer wall surface at the time of closing is small, so that the upper movable rail does not move. Prospect width and burden load are suppressed.

When the rain door is opened, the preceding door plate moves from the closed track to the inside of the room and is stored, so that no space is wasted between the preceding door plate and the outer wall, and the space beside the opening is effective. In addition, the trailing door plate moves on the orbit at the time of closing to the position where the preceding door plate has moved to the opening side and is stored as it is, so that the protruding amount from the outer wall surface of the rain door at the time of opening is the same as that at the closing time. Equally, the width of the outer wall protruding from the outer wall is reduced at the time of opening, and the appearance design is enhanced both at the time of closing and at the time of opening.
