BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rain door in which a door plate is stored in a state of being projected from a lateral frame when opened.

[0002]

2. Description of the Related Art A rain door containing a door plate stores the door plates on one side or on both sides of the opening when the door is opened. Therefore, a door bag for storing the door plate is installed beside the opening frame. However, this door bag not only reduces the appearance and design of the doorboard when it is closed, but also complicates the construction.
Focusing on this point, Japanese Patent Publication No. 60-35518 proposes a rain door in which the door pocket is absent by supporting the door plate in a state of overhanging it when it is stored.

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 in 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. Although the door pocket is made absent by moving it to one side of the opening frame together with the movable frame, when the door plate is cantilevered by the upper and lower movable frames when fully opened, the horizontal frame of the lower movable frame and the upper movable frame is Since the vertical load of the door plate and the moment to invert the door plate act on the part protruding from the movable frame, the movable frame is liable to bend due to the vertical load, and the moment causes the lower movable frame to move toward the horizontal frame and Since it receives a force to move from the horizontal frame to the open side, it tends to hang down from the horizontal frame together with the door plate.

The present invention has been made by paying attention to the problem of storing a rain door in which a door plate is extended from a horizontal frame and supported, and is intended to newly propose a rain door having a high retainability of the door plate in the stored state. is there.

[0005]

According to the present invention, between the vertical frame of the opening frame and the vertical frame of the door plate, a connecting link connecting both vertical frames and an auxiliary link connecting the connecting link and the vertical frame of the opening frame are installed. Then, the end of the connecting link on the door plate side is pivotally supported on the vertical frame, and at the same time, the connecting link and the auxiliary link, which are connected to each other, are supported by the vertical frame of the opening frame at two points, thereby vertically loading the door plate. And load the moment on the vertical frame of the opening frame,
The load of the movable frame is eliminated, its bending and axial movement are prevented, and the hanging state of the door plate is maintained while preventing the movable frame from sagging when the door plate is stored.

On the horizontal frame of the opening frame, a movable frame that relatively moves in the longitudinal direction is supported so as to project from the end of the horizontal frame.
The door plate is connected to the movable frame, and moves in the length direction with respect to the horizontal frame together with the movable frame to open and close.

The door plate has a vertical frame on the open side. A connecting link is installed between the vertical frame and the open frame on the open side of the door plate, and both vertical frames are connected by the connecting link. An end of the connecting link on the vertical frame side of the door plate is pivotally supported by the vertical frame, and an end of the opening frame on the vertical frame side is supported by the vertical frame so as to be movable in the longitudinal direction. The end portion of the connecting link on the side of the opening frame is supported by the vertical frame of the opening frame by being locked by the vertical frame of the opening frame and stopped when the door plate is opened. The connecting link is axially supported by the vertical frame of the door plate, while being supported by the vertical frame of the opening frame, it receives its load at the axial support position of the door plate and transmits it to the vertical frame of the opening frame.

The auxiliary link is installed between the intermediate portion of the connecting link and the vertical frame of the opening frame to connect the connecting link and the vertical frame of the opening frame. The end portion of the auxiliary link on the side of the opening frame is axially supported by the vertical frame, and the auxiliary link is axially supported by the vertical frame of the opening frame while being connected to the connecting link, so that the load of the door plate received by the connecting link is the connecting link. Along with the transmission to the vertical frame.

The vertical load of the door plate received at the pivotal support position of the connecting link to the door plate is borne by the vertical frame at two positions of the connecting link, the supporting position of the opening frame to the vertical frame and the axial supporting position of the auxiliary link. It

Further, the moment due to the load of the door plate acts around the axial support position of the auxiliary link to the vertical frame of the opening frame,
Since the connecting link and the auxiliary link connected to each other are respectively supported by the vertical frames of the opening frame, resistance moments of couples are generated at the two supporting positions in opposite directions to the moments, and the resistance moments cause the opening frame. The vertical frame of resists the moment of external force.

The vertical load and the moment of the door plate are transmitted to the vertical frame by the connecting link and the auxiliary link, and the load is applied to the vertical frame so that the load of the movable frame is not burdened and its bending and axial movement are prevented, and the movable frame is moved. The hanging of the frame and door plate is prevented.
