[Problems to be solved by the invention]
However, in such a door, as shown in FIG. 11, the pivot point (rotation center of the hinge) c between the main arm a and the door frame b, the pivot point e between the main arm a and the door body d, In the relationship of the sliding pivot point f of the door body d supported by the sliding groove formed in the door frame b, when the door body d is opened, the sliding pivot point f is closer to the pivot point c side than the pivot point e. When positioned, if the main arm a is always turned clockwise in FIG. 11, the sliding pivot point f moves further toward the pivot point c and does not close itself.
Therefore, in order to always keep the door body d closed automatically, the relationship between the door body d and the angle at which the main arm a intersects, the length of the main arm a, etc. at the time of opening always corresponds to various opening widths. It was cumbersome to consider.
In addition, the rotation range (angle) of the main arm from the closed position to the open position is limited due to the relationship between the angle at which the door body and the main arm intersect when opened, and the relationship between the angle between the sliding groove and the door body. Since the rotation angle is limited, the initial self-closing speed is increased, especially when a wheelchair user passes, which is not sufficient in terms of safety.
For this reason, it is necessary to provide a hinge with a control mechanism for controlling the initial self-closing (self-opening) speed, which is not only expensive, but also has a large hinge, which is not preferable from an aesthetic point of view.
[0004]
The present invention has been made in view of such problems, and has a simple structure, is not affected by the angle of intersection of the door body and the arm when opened, and closes (opens) suddenly. It is an object to provide a door device that can easily adjust the closing speed.

【The invention's effect】
According to the first aspect of the present invention, the guide member is guided through the force accumulation mechanism so that the guide member is guided so as not to rotate with respect to the guide groove, and the turning force is always applied to the door body in the closing direction. Since the door is pivotally connected, the opening position of the door body is not affected by the rotation position of the door support frame, and the opening position of the door body can be selected over a wide range.
Furthermore, since the rotation angle from the closed position to the open position of the door body can be set large, the self-closing speed can be adjusted in a large range, and a smooth movement can be obtained when the door body is closed.
In addition, since the turning power adjusting member can be rotated from the outside of the center shaft, the turning power adjusting member is mounted in a state in which the door body is incorporated in the door support frame and the guide member is slidable in the guide groove. The initial closing speed can be easily adjusted.
