て扉がずれてしまう危険があつた。 In this kind of conventional door opening/closing device, the door is supported so as to be biased to open or close at a certain rotation angle. However, no consideration is given to the vertical displacement of the door, and therefore, if such a device is used in a refrigerator, etc., there is a risk that the door may shift due to vibrations during transportation. It was hot.

Among the hinges 4, 5, and 6, the lower hinge 6 employs the device of the present invention. That is, 7 is a hinge base fixed to the front corner of the main body 1, and 8 is a cylindrical hinge pin installed on the hinge base 7, which fits into the hole 9 on the lower end surface of the refrigerator compartment door 3. A square seat 10 rotatably supports the door 3 and has a corner 10a and a surface 10b in the middle. Reference numeral 11 denotes a plastic member fixed to the corner of the lower end surface of the refrigerator compartment door 3 with a screw 12, and the seat 10 is elastically clamped so as to be freely rotatable by an elastically deformable bifurcated clamping part 11a formed at the tip. are doing. The fitting surface P of the clamping part 11a of the member 11, the corner part 10a of the seat 10, and the surface part 10b is arranged so that the fitting between the clamping part 11a and the seat 10 does not shift vertically or horizontally. Lower ends 10c, 11b, small, upper ends 10d, 11
It is formed into a taper with a large value c.

are pushed out by the corner portions 10a of the seat 10 against the elastic force. If the door opening force is removed below the dead point of approximately 45 degrees, the refrigerating compartment door 3 will automatically close as shown in FIG. 4 due to the elastic force of the clamping portion 11a. Conversely, if the opening angle is greater than the dead center, even if the opening force is removed, the gripping portion 11a
The refrigerating compartment door 3 automatically opens due to the elastic force and stops at an angle of 90° as shown in FIG. Furthermore, even when such a door is opened and closed, the fitting surface P between the seat 10 and the clamping part 11a is
The lower ends 10c, 11b of 1a are small, the upper end 10d,
11c, so that the refrigerating compartment door 3 does not shake vertically or horizontally due to vibration or the like, and the seat 10 and the holding portion 11a do not come off.

When the door is placed in the closed or open position, the door is rotated relative to the hinge pin and the face of the seat is held, and the door is held at the corner of the seat below the dead center angle. a member having an elastically deformable clamping part that biases the door in the opening direction when the door is closed or above the dead center angle; Since the lower end is tapered small and the upper end is large, it is possible to automatically open and close the door from the dead center angle using the elastic force of the gripping part, making it easy to transport the product. Since the fitting between the clamping part and the seat does not come off even when there is vibration inside the door, it has practical effects such as ensuring reliable opening and closing without causing the door to shift.
