Description

DETAILED DESCRIPTION OF THE INVENTION The present invention mainly relates to a hinge device for connecting panels of a folding door in an openable and closable manner.

Conventionally, as shown in FIG. 9, for example, as shown in FIG. 9, this hinge device has two parallel bearings 43 placed approximately at the center of a plane portion 42 corresponding to the diameter of a hinge body 41 having a semicircular cross section.
In some cases, a cylindrical shaft 45 formed in a corner of an end edge of a panel 44 over the entire length in the longitudinal direction is rotatably fitted into the bearing 43.

However, in the above-mentioned conventional device, in order to prevent the shaft 45 of the panel 44 from coming out from inside the bearing 43, it is necessary to make the width of the side opening of the bearing 43 smaller than the outer diameter of the shaft 45. However, in order to rotate the panel 44 approximately 90 degrees from the position shown by the solid line in Figure 9 to the folded position shown by the two-dot chain line in Figure 9, the width must be made slightly smaller than the outer diameter. Therefore, not only dimensional accuracy is required, but also the shaft 45 is easily removed from the bearing 43, which is a drawback.

In order to prevent this, a locking pin 47 fixed to the lower surface of the connecting plate 46 as shown in FIG. There was a defect in that the hinge body 41 had to be tightened and fixed to the upper end surface.

Furthermore, if the thickness of the connecting piece 49 between the panel 44 and the shaft 45 is increased, the opening/closing angle of the panel 44 becomes smaller, so the thickness of the connecting piece 49, which requires strength, can be increased.
There were also problems with strength.

The object of the present invention is to form a bearing recess with a substantially semicircular cross section near the center of a flat part corresponding to the diameter of an elongated hinge body with a roughly semicircular cross section, and to a hook portion is formed to cover the bearing recess from approximately the center of the
On the other hand, a substantially semi-cylindrical shaft cylinder part is formed at the end edge of the panel to be rotatably fitted into the bearing recess, and a hook part which is locked to the hook part is formed at the inner end of the coaxial cylinder part. By providing a hinge device, the hinge body and the panel can be reliably connected without increasing processing accuracy or using a separate connecting member, and the structure can be made durable. It's about doing.
