Abstract

PROBLEM TO BE SOLVED: To simplify the structure, reduce the manufacturing cost and precisely hold a rotating body in close and open positions by forming a link mechanism for mutually connecting wing plates an fixed frame side and rotating body side of a plurality of arms, and fitting a guide pin into the parallel end part of a guide groove in closing and opening of the rotating body. SOLUTION: This hinge is formed of a fixed frame side wing plate 1 fixed to a fixed frame 8, a rotating body side wing plate 2 fixed to a rotating body 9 such as door, projecting arms 3, 4 and support arm 5 for connecting them in such a manner as to be bendable. The end of the protruding arm 4 is fixed to the middle part of the wing plate 2, and the base end part is connected to the wing plate 1 by a guide pin 7 inserted to the guide groove 6 of the wing plate 1. The guide groove 6 has a main body part 6a inclined to the longitudinal direction of the fixed frame side wing plate 1 and a base end part 6b and top end part 6c parallel to the longitudinal direction, and the guide pin 7 is engaged with the base end part 6b when the rotating body 9 is in closed state, and engaged with the top end part 6c when the rotating body 9 is in opened position.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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 taking a large opening angle by taking out a product to make it easier to take in and out of articles, 2. Description of the Related Art A fixed frame and a rotating body are connected by various link mechanisms.

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

However, a conventional so-called internal hinge has a large number of link mechanisms as disclosed in Japanese Patent Application Laid-Open No. Sho 59-10464, has a complicated shape, and requires a high manufacturing cost. Also, even if you try to leave the door open, it will close naturally due to wind pressure unless you hold it down with a stay bracket or the like. Furthermore, simply closing the door may open over time. This is because the hinge itself does not include a function for fixing and holding the rotating body.

[0005]

SUMMARY OF 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, effecting the sealing of the rotating body, and accurately fixing the hinge 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 according to 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 longitudinal intermediate portions, and the base end of the take-out main arm 3 is pivotally connected to the fixed frame side blade 1.
The distal end of the take-out arm 3 is pivotally attached to the base end of the support arm 5. The tip of the take-out sub-arm 4 is pivotally attached to an intermediate portion of the rotary body-side vane plate 2, and the base end of the take-out sub-arm 4 is fixed to the fixed frame body by a guide pin 7 inserted into the guide groove 6 of the fixed frame-side vane 1. It is connected to the side blade 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 body portion 6a inclined with respect to the longitudinal direction of the fixed frame body blade 1, a base end portion 6b and a distal end portion 6c parallel to the longitudinal direction, and the rotating body 9 is in a closed state. , The guide pin 7 engages with the proximal end portion 6b, while the guide pin 7 engages with the distal end portion 6c when the rotating body 9 is in the open position.

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 auxiliary arm 4 is
And slides into the main part 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, and 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 take-out main 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]

According to the hinge of the present invention, the fixed frame side blade 1
Since the link mechanism that connects the rotary body-side vane plate 2 and the rotary body side blade plate 2 has three configurations of the take-out arm 3, the take-out arm 4, and the support arm 5, the overall configuration of the butterfly plate is simplified, and the manufacturing cost 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 at the closed position, and a desired sealing effect is obtained.

When the rotating body 9 is opened, the guide pin 7 enters the tip 6c 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.
