Description

[Detailed description of the invention]

[0001]

TECHNICAL FIELD The present invention relates to a biaxial hinge used for a closed door such as a hatch cover of a ship.

[0002]

2. Description of the Related Art In a conventional biaxial hinge, a stationary blade and a connecting plate are connected via a first shaft, and a rotating blade and a connecting plate are connected via a second shaft.

However, in such a hinge, when the door is closed, the door is pressed outward due to the compressive stress of the waterproof packing attached to the fixed frame body such as the box body, and the first shaft and the second shaft are respectively pushed. The hinge partially rotates around the center like a knife, causing the door to rise.

Further, when the hinge is attached, the connecting plate projects, so that the door cannot be attached flush with the front of the door and the front of the fixed frame such as a box.

[0005]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to install and store the front surface of the door and the front surface of the box flush with each other, to allow flat mounting without protrusions, and to provide a stopper mechanism for stopping the hinge from bending. It is an object of the present invention to provide a biaxial hinge that can prevent the lift of the door and enhance the sealing property of the closed door.

[0006]

Means for Solving the Problems Hereinafter, the description will be given with reference numerals in the attached drawings. In the biaxial hinge of the present invention, a fixed side vane 3 is fixed to a fixed frame body 1 and a rotating door 2 is provided. The rotating-side blade 4 is fixedly attached to the fixed-side blade 3, the E-type retaining rings 6a and 6b are attached between the stopper hinges 5a and 5b, and the stopper hinge 5 is provided between the bearing tube portions 9a and 9b at the base end of the fixed-side blade 3. One end portion of the stopper hinge 5 is inserted between the bearing cylinder portions 10a and 10b at the base end portion of the rotating-side blade 3, and the other end portion of the stopper hinges 5a and 5b is inserted into the bearing cylinder portion. The first shaft pin 13 is fitted and inserted into the bearing tubular portions 11a and 11b and the bearing tubular portions 9a and 9b, and the second axial pin 14 is attached to the bearing tubular portions 12a and 12b and the bearing tubular portions 10a and 10b at the other ends of the stopper hinges 5a and 5b. And insert it into contact with the stopper surface 15 of the stopper hinge 5 when the door is closed. The stopper projections 7 and 8 are provided at the base ends of the blades 3 and 4.

When the door is closed, the stopper projection 7 of the fixed-side blade 3 contacts the stopper surface 15 of the stopper hinge 5 to suppress the rotation of the stopper hinge 5 in the door-closing direction, and the stopper projection 8 of the rotating-side blade 4 stops. The contact with the surface 15 suppresses the rotation of the rotating-side blade 4, and the rotating-side blade 4 and the stopper hinge 5 are fixed in a straight line.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION In the illustrated embodiment, a fixed side blade 3 having three fixing bolt holes 16a provided in a triangular shape is fixed to a fixed frame body 1 such as a box body with a hexagon bolt 17 to fix the fixed bolt. The rotating side vanes 4 having three triangular holes 16b are fixed to the revolving door 2 of a refrigerator or the like with hexagon bolts 17, and the fixed side vanes 2 and the stopper hinges 15 are fixed by the first shaft pin 13 so as to freely rotate. The rotation side vane 4 and the stopper hinge 15 are connected by the second shaft pin 14 so that they can be freely rotated in the door opening direction.

As shown in FIG. 4, when the door is closed, the stopper projection 7 of the fixed-side blade 3 contacts the stopper surface 15 of the stopper hinge 5 to suppress the rotation of the stopper hinge 5 in the door-closing direction and to rotate the blade on the rotating side. The stopper projection 8 of 4 abuts against the stopper surface 15 to suppress the rotation of the rotating side blade 4 and fix the rotating side blade 4 and the stopper hinge 5 in a straight line, and the waterproof attached to the fixed frame 1 Eliminates the lifting of the revolving door 2 due to the compressive stress of the packing 18 for use.

As shown in FIG. 5, when the door is opened 90 degrees, the rotary vane 4 rotates 90 degrees about the second axis, and the back surface of the stopper projection 8 of the rotary vane 4 is a stopper hinge. It contacts the stopper surface 15 of the rotary blade 5 and suppresses further rotation of the rotary vane 4.

As shown in FIG. 6, when the door is opened 180 degrees, the stopper hinge 15 rotates 90 degrees around the first axis, and the stopper surface 15 of the stopper hinge 5 causes the stopper projection 7 of the fixed-side blade 3 to rotate. The stopper hinge 5 is prevented from further rotating, and the revolving door 2 is opened 180 degrees with respect to the fixed frame body 1.

[0012]

As described above, in the biaxial hinge of the present invention, the fixed-side blade 3, the rotating-side blade 4 and the stopper hinge 5 are arranged in a straight line, and the fixed frame 1 front surface of the box body or the like is arranged. It is mounted and stored flush with the front surface of the revolving door 2 and can be mounted on a flat surface without the shaft portion protruding.

Further, according to the present invention, each vane 3,4 that abuts the stopper surface 15 of the stopper hinge 5 when the door is closed has stopper projections 7,8, and the stoppers of each vane 3,4 are closed in the door closing direction. The protrusions 7 and 8 are brought into contact with the stopper surface 15 of the stopper hinge 5 to suppress the rotation of the hinge about the first axis and the second axis respectively, and the hinge is linearly moved to a predetermined closed position. It is possible to improve the airtightness of the door by fixing the door to the revolving door 2 to prevent it from floating.
