2. Description of the Related Art In a conventional structure of a suspension door side of a revolving door, as shown in FIGS. 4 and 5, a sealing material 25 is fixed to the revolving door 26, and a biaxial shaft fixed to the revolving door 26. The connecting plate 23 is connected to the rotary side blade 21 of the hinge 35 via the first shaft pin 24, and the fixed side blade 22 of the biaxial hinge 35 is connected to the connecting plate 23 via the second shaft pin 34. .

However, since the rotating blades 21 and the connecting blades 23 can freely rotate and the connecting plate 23 and the fixed blades 22 can freely rotate, the connecting blades 23 and the rotating blades 21 can be fixed when the door is closed. This may not be possible, and the rotary side blade 21 and the first shaft pin 24 portion of the connecting portion 23 may float.

There is no sufficient space between the rotary door 26, the rotary vane 21 and the fixed frame 27, and a simple seal material 25 such as an L-shape is fixed to the rotary door and provided on the seal material 25. Further, since only one place of the fixed frame 27 is pressed by the lip piece 25a, there is a problem in sealing effect.

In the following, referring to the reference numerals in the accompanying drawings, in the structure of the suspension door of the present invention, the rotary door 6 is provided with the rotary vane 1 of the biaxial hinge 15. By fixing, the fixed-side blade 2 of the biaxial hinge 15 is fixed to the fixed frame body 7, and one end of the connecting plate 3 is inserted between the bearing cylinders 9 and 9 at the base end of the rotary-side blade 1. The other end of the connecting plate 3 is inserted between the bearing cylinders 10, 10 at the base end of the fixed-side blade 2, and the biaxial hinge is inserted in the bearing hole 11 and the bearing cylinders 9, 9 at one end of the connecting plate 3.
Fitted to the first shaft pin 4 of 15, the connecting plate 3 of the bearing hole 11 fitted insert the second shaft pin 14 of the biaxial hinge 15 into the bearing hole 12 and the bearing cylinder portion 10, 10 of the other end portion first A bearing hole 1 provided in a fixed-side blade 2 that surrounds the connecting plate 3 by inserting the shaft pin 4 therein.
No. 0 and the bearing hole 12 provided in the connecting plate 3, the second shaft pin 14 is inserted and fixed, and the fixed side vane 3 is fixed to the fixed frame 7.

Further , when the door is closed, the back surface portion 1a of the rotary side vane 1 is closed.
And a stopper protrusion 3a that comes into contact with the surface portion 7a of the fixed frame body 7 is provided on one end side of the connecting plate 3, and a step portion 1b is formed on the rotary side vane 1 to form a step on the rotary side vane 1. between the portion 1b and the rotary door 6 and the fixed frame 7, H-type sealing material 5 to form a space 8 for accommodating the, H-type sealing material accommodated in the space 8 and fixed to an end portion of the revolving door 6 Two lip pieces 5c, 5 of 5
d is pressed against the fixed frame body 7 at two points.

[0008]

As shown in FIG. 2, when the door is closed, the biaxial hinge 15
The protrusion 3a for the stopper abuts the back surface 1a of the rotating-side blade 1 to suppress the rotation of the rotating-side blade 1 and the connecting plate 3 in the door closing direction, and fixes the rotating-side blade 1 and the connecting plate 3 in a straight line. To do.

The lip pieces 5c and 5d of the sealing material 5 fixed to the end portion of the revolving door 6 are pressed against the fixed frame body 7 at two points to enhance the hermeticity. In the door opening direction, the rotating side vane and the connecting plate freely rotate about the first shaft pin 4, and the connecting plate 3 and the fixed side vane 2 also rotate about the second shaft pin 14 so that they rotate. The door 6 can be opened up to 270 degrees where it abuts the side surface of the fixed frame body 7.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated embodiment, a rotary vane 1 having fixed countersunk screw holes 13a provided at three points on the apex of a triangle is fixed to a rotary door 6 of a truck with a countersunk screw, and is used for a fixed countersunk screw. Hole 1
Fixed side vanes 2 provided with 3b at three points on the apex of a triangle
Is the side surface portion 7 of the fixed frame body 7 which is the container portion of the truck.
is secured by countersunk screws to c, rotation-side blade 1 and the connecting plate 3 is coupled with the first shaft pin 4 as freely rotate relative to each other in the opening direction
The connecting plate 3 and the fixed-side blades 2 are connected by the second shaft pin 14 so as to freely rotate with respect to each other .

Rotating side vanes 1 bent in the direction of the surface of the revolving door
The step portion 1b at the base end portion of the
Has a space 8b that surrounds the revolving door 6 in the space 8b.
The fixed H-type sealing material 5 has two lip pieces 5 on one side.
The edge portion of the revolving door 6 is sandwiched by a and 5b.
That is, the one lip piece 5a contacts the surface of the revolving door 6.
However, the other lip piece 5b is in contact with the back surface of the revolving door 6.
It In the space 8a between the revolving door 6 and the fixed frame 7 ,
H-type seal protruding to the opposite side from the lip pieces 5a and 5b
Two lip pieces 5c and 5d of the material 5 are two pieces on the fixed frame body 7.
Press in place and create a sealing effect.

The stopper projection 3a of the connecting plate 3 which is close to or in contact with the back surface 1a of the rotating side blade 1 is set so as to fix the rotating side blade 1 and the connecting plate 3 in a straight line when the door is closed.
It has a height. When the revolving door 6 is moved in the closing direction, the back surface 1a of the rotating-side blade 1 projects from the connecting plate 3 for the stopper.
Since the rotating side vane 1 and the connecting plate 3 are fixed in a straight line and rotate at the same angle by contacting the portion 3a, the rotating side vane 1 and the connecting plate 3 can be simultaneously fixed to a predetermined closed position. .

[0013]

[Effects of the Invention] As described above, the suspension side structure of the revolving door of the present invention
In the construction, the step portion 1b is formed on the rotating side blade 1 of the biaxial hinge 15.
And a space 8 sufficient to accommodate the H-shaped seal material 5 is provided between the step portion 1b, the revolving door 6 and the fixed frame body 7 .
Since the H-shaped sealing material 5 is fixed to the end of the revolving door 6 in the space 8, the two lip pieces 5c and 5d of the H-shaped sealing material 5 are attached to each other.
Therefore, it is possible to seal two places at the same time, and it is possible to enhance the sealing effect of the revolving door .

Further , the biaxial hinge used in the hanging side structure of the present invention.
The jig 15 has a connecting plate 3 provided with a stopper protrusion 3a that abuts the back surface 1a of the turning-side blade 1 when the door is closed, and the back surface 1a of the turning-side blade 1 is connected to the connecting plate 3 in the door closing direction. Three
Since the rotating protrusions 3a are brought into contact with each other and the rotating-side blade 1 and the connecting plate 3 rotate at the same angle, it is possible to fix the connecting plate 3 and the rotating-side blade 1 linearly at the same time in a predetermined closed position. it can
