BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge used for rotatably attaching a rotating body such as a door to a fixed frame such as a door frame.

[0002]

2. Description of the Related Art In general, a take-out type hinge is used to open and close a rotating body having a large thickness. As a method of increasing an opening angle by taking out a product to make it easier to put in and take out articles. In addition, the fixed frame and the rotating body are connected by various link mechanisms.

In the case of an internal type in which the hinge is mounted over the inner surfaces of the fixed frame body and the rotating body frame, it is preferable that the link mechanism does not protrude out of the frame when the door is closed, which is simply the appearance of the hinge. Not only that, it also prevents damage to the stored items due to the overhang of the hinges, and contributes to reducing work disturbance when opening the door.

However, a conventional so-called internal hinge has a large number of link mechanisms, as disclosed in Japanese Patent Application Laid-Open No. Sho 59-10264, has a complicated shape, and requires a high manufacturing cost. Also, even if you try to keep the door open, it will close naturally due to wind pressure unless it is held down with stay brackets. Furthermore, simply closing the door may open over time. This is due to the fact that the hinge itself does not include the function of fixing and holding the rotating body.

[0005]

[Problems to be Solved by the Invention] Accordingly, an object of the present invention is to provide a hinge capable of reducing the manufacturing cost by simplifying the shape and structure of the hinge, sealing the rotating body, and accurately fixing the rotating body when opened. That is.

[0006]

Means for Solving the Problems Hereinafter, a description will be given using reference numerals in the accompanying drawings. The hinge of the present invention includes a fixed frame side wing plate 1 fixed to a fixed frame 8 such as a door, a door and the like. And a take-out main arm 3, a take-out sub-arm 4 and a support arm 5 for connecting the wing body side blades 2 fixed to the rotator 9 to bend and extend freely. The take-out main arm 3 and the take-out sub-arm 4 are pivotally connected at their intermediate portions in the longitudinal direction. The base end of the take-out main arm 3 is pivotally connected to the fixed frame-side blade 1, and the tip of the take-out arm 3 is It is pivotally attached to the base end of the support arm 5. The distal end of the take-out sub-arm 4 is pivotally attached to the intermediate portion of the rotating body-side vane plate 2, and the base end of the take-out sub-arm 4 is fixed by a guide pin 7 inserted into the guide groove 6 of the fixed frame-side vane plate 1. It is connected to the side wing plate 1. The tip of the support arm 5 is pivotally attached to the rotating body side blade 2. The guide groove 6 has a main part 6a inclined with respect to the longitudinal direction of the fixed frame body blade 1, a base end part 6b and a distal end part 6c parallel to the longitudinal direction, and the rotating body 9 is in a closed state. When the rotating body 9 is in the open position, the guide pin 7 engages with the distal end portion 6c while the guide pin 7 engages with the proximal end portion 6b.

When the rotating body 9 is pulled forward from the closed state in FIG. 1, the take-out main arm 3 rotates clockwise around the shaft pin 10 at the base end, and the rotating body 9 separates from the fixed frame 8. As shown in FIG. At this time, the guide pin 7 of the take-out sub-arm 4 comes out of the base end portion 6b of the guide groove 6 and slides to the main portion 6a. The take-out sub-arm 4 and the support arm 5 regulate the rotational movement of the take-out main arm 3 together with the guide pin 7. When the guide pin 7 slides into the distal end portion 6 c of the guide groove 6, the rotating body 9 becomes the fixed frame 9. It is opened in a form that has been taken out from the front by a certain distance.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The main take-out arm 3 is long in order to obtain a take-out amount of a rotating body, and a recess 15 for escape of a guide pin 7 is provided on a side surface. In order to fit the hinge compactly when closed, the center of the rotating body side blade 2 is raised so as not to hit the projection of the fixed frame side blade 1.

[0009]

[Effects of the Invention] In the hinge of the present invention, the link mechanism for connecting the fixed frame-side wing plate 1 and the rotating body-side wing plate 2 is composed of the take-out arm 3, the take-out arm 4, and the support arm 5. The overall configuration is simplified, and manufacturing costs can be reduced.

When the rotating body 9 is closed, the guide pin 7 enters the parallel base end portion 6b of the guide groove 6, so that the rotating body 9 is accurately held in the closed position, and a desired sealing effect can be obtained.

When the rotating body 9 is opened, the guide pin 7 enters the tip portion 6c on the guide groove 6 parallel to the guide groove 6, so that the rotating body 9 is accurately held at the open position and accidentally closed by wind pressure or the like. There is no rotation.
