Abstract

PROBLEM TO BE SOLVED: To provide a safe and inexpensive auto-closing door apparatus which allows a passenger to operate a door and to smoothly pass the same with simple operation and with little change of direction of the passenger body, and is not under the influence of a power failure. SOLUTION: A door main body 3 is installed so as to be guided by a main arm 8 to horizontally move in a door frame 2 while rotating in the same. The main arm 8 has a projecting butt hinge 10 attached thereto, which hinge includes various mechanisms like a power storage mechanism for imparting power in a door closing direction and a cushioning mechanism for controlling the door closing speed. When the door main body 3 is manually moved toward a door opening side, the door main body 3 rotatively moves to be opened. On the other hand, when the door main body 3 assuming the opened position is released (the hand of the passenger is moved off), auto-closing power of the projective butt hinge 10 allows the main arm 8 to perform closing action. As a result, the door main body 3 automatically moves while performing automatic closing rotation, to be closed.

<Effects of the Invention According to Claim 3> In addition to the effects of the inventions described in claims 1 and 2, the following effects are obtained. That is, since the door closing force is obtained by the take-out hinge, there is an advantage that the take-out hinge can be concealed upward. In addition, since there is a buffer mechanism for controlling the speed, the closing speed can be set to a gentle and constant speed without danger, and a safety door device that gives a sense of security is realized.

<Effects of the Invention According to Claim 4> The following effects are obtained in addition to the effects of the invention described in claim 1.
That is, since the hinge-type self-closing hinge doubles as a door closer, a simple and beautiful scenery without a sense of incongruity is realized without protruding portions. Also, since the hinge type self-closing hinge is provided on the side of the rotating body and the side of the doorway frame, any number of hinge type self-closing hinges can be provided,
Alternatively, it can be used in conjunction with an ordinary hinge or another self-closing hinge device, and easily realizes a self-closing automatic door device having various characteristics. In addition, since there is a buffer mechanism for controlling the speed, the closing speed can be set to a gentle and constant speed without danger, and a safety door device that gives a sense of security is realized.

<Effects of the Invention According to Claim 5> In addition to the effects of the invention described in claim 1 or 3, it is possible to hide hardware, shafts, hinges, etc., thereby realizing a door device with a good view. it can.

<Effect of the invention according to claim 6> When the door body in the opened state is released, the door body is automatically closed and moved by the door pulling means so that the door body moves and closes. Therefore, even with such a configuration, the same effect as that of the first aspect can be obtained.
