In addition, Japanese Laid-Open Patent Publication No. Hei 6-62166 discloses a biaxial hinge used in a sealed switch type sill for use in a cold storage vehicle or the like. The biaxial hinge fixes the rotating side hinge body to the sill, fixes the fixed side hinge body to the opening frame, and connects the connecting hinge body to the hinge bodies by two pins. The rotating side hinge system can rotate freely about 90 degrees with respect to the joint hinge body, and the joint hinge system can be set to be freely rotated about 180 degrees with respect to the fixed side hinge body.

The biaxial hinge of Japanese Laid-Open Patent Publication No. Hei 6-62166 is capable of rotating the hinge body at a wide angle, and has an advantage that the switch angle of the threshold can be set large. However, due to the difference in the use and the position of the sill hinged by the two-axis hinge, the hinge body can rotate freely at a wide angle during the operation of the sill switch, which is not ideal, and is used in a butterfly hinge such as a pivot type sill. There is also a case where a locking mechanism or a brake mechanism is provided between the hinge bodies in order to control the switching action. As described above, the locking mechanism or the brake mechanism increases the number of constituent parts of the hinge body by an increase in the number of constituent parts, and thus the cost of the butterfly hinge for the sill is increased.

In the biaxial hinge device of the present invention, the movable hinge body is provided with first and second abutting portions, and the connecting hinge body is provided with first and second abutting portions; when the two hinge bodies are facing the second shaft member When the front and rear directions are respectively rotated relative to each other, the first abutting portions or the second abutting portions are respectively in contact with each other, and the rotation in both the forward and reverse directions can be controlled to a desired angle. Thereby, between the movable hinge body and the joint hinge body, unnecessary relative rotation in the switching operation of the sill is not caused, and the sill and the fixed side main body portion are sealed so as not to form a gap. It is permitted to adjust the relative rotation of the movable hinge body to the extent of the relative angle of the hinge body.

In the biaxial hinge device of the present invention, it is preferable that an elastic member for biasing the two hinge bodies is disposed between the movable hinge body and the joint hinge body. Since the movable hinge body and the joint hinge body are often biased by the elastic member, the two hinge bodies can be prevented from excessively contacting each other, and the noisy metal collision sound can be suppressed.

Further, in the biaxial hinge device of the present invention, as a stopping means for stopping the sill at a predetermined angle when the sill is rotated in the opening direction, it is preferable that the stopping convex member is detachably provided on the side of the fixed hinge body, and The connection hinge body is formed with a stop abutting portion that abuts against the stop convex member. By stopping the convex member thereby, the switching angle of the threshold can be appropriately adjusted.

Further, Fig. 6(a) shows a state in which the hinge body 12, that is, the door sill 31 is rotated by 120°, is opened. This switching angle can be changed to a desired angle by appropriately adjusting the arrangement and angle of the stop abutting portion 12d.

On the other hand, Fig. 6(b) shows a state in which the stopper convex member 16 is not attached. At this time, the joint hinge body 12 is rotatable until the body portion 12a comes into contact with the body portion 11a of the fixed hinge body 11. In Fig. 6(b), although the connection hinge body 12 is rotatable to 195°, the switch angle can be changed by appropriately adjusting the shape of the main body portion 11a of the fixed hinge body 11. angle.

Next, the relative rotational action of the joint hinge body 12 and the movable hinge body 14 will be described.

When the connection hinge body 12 and the movable hinge body 14 are pivotally connected by the second shaft member 15, the respective step portions 12e and 14e are disposed to face each other, and between the step portions 12e and 14e, the first portion is secured. 4 The extent of the gap shown. Then, the joint hinge body 12 and the movable hinge body 14 are relatively rotated, and as shown in FIG. 7(a), when the first abutting portions 12g and 14g abut each other, the joint hinge body 12 and the movable hinge body become the joint hinge body 12 and the movable hinge body. The relative angle of 14 is the narrowest state. At this time, the interval H1 when the movable hinge body 14 is kept parallel with respect to the apparatus main body portion 32 is minimized.

On the other hand, when the connecting hinge body 12 and the movable hinge body 14 are relatively rotated in the opposite directions, as shown in FIG. 7(b), the second abutting portions 12h and 14h abut each other to form the joint hinge body 12 and The relative angle of the movable hinge body 14 is the most enlarged. At this time, the interval H2 when the movable hinge body 14 is kept parallel to the apparatus main body portion 32 is maximized. As described above, the first abutting portions 12g and 14g and the second abutting portions 12h and 14h function as a rotation restricting portion that restricts the mutual rotation of the hinge body 12 and the movable hinge body 14.

Therefore, when the sill 31 is opened and closed, the joint hinge body 12 and the movable hinge body 14 mutually restrict their rotation, and as shown in Figs. 6(a) and (b), the fixed hinge body 11 can be maintained substantially the same relative. Angle to make it back. Therefore, it is possible to prevent the hinge bodies from being excessively rotated relative to each other in the manner of the conventional biaxial hinge device to hinder the disadvantage of the switching operation.

Further, in order to make the door sill 31 adhere to the opening 33 of the apparatus main body portion 32, when the entry door 31 is pushed, the movable hinge body and the joint hinge body are relatively rotated in the range shown in Figs. 7(a) and 7(b). Since the position in the height direction is finely adjusted, the sill 31 can be placed at the optimum height for sealing while being horizontal with respect to the apparatus main body portion 32.
