Description

[Detailed Description of the Invention] The present invention relates to an improvement of a cabinet door hinge device that can open the door 180 degrees.

A hinge that allows the door to open 180 degrees has been known for some time, but when this hinge is used, the shaft of the hinge protrudes forward from the door surface when the door is closed.
Not only did it obstruct people passing in front of the cabinet, but it also had the disadvantage of being unsightly.

However, in order to eliminate and solve the above-mentioned drawbacks, the present invention uses a two-axis rotation system for the door so that the shaft does not protrude from the door surface. explain.

That is, a receiving piece 2 having a rounded notch 21 and having the same thickness and width as the door ₃ is fixed to one of the upper and lower ends of the opening of the cabinet body 1, and a receiving piece 2 having the same thickness and width as the door 3 is fixed to one end of the receiving piece. One end of the rotating piece 5, which is pivotally attached to the upper and lower ends of the door via a pin 4, is pivotally attached 6, and a pin 7 guided to the edge of the cutout recess ₂₁ of the receiving piece 2 is attached to the upper and lower ends of the door. It is characterized by a fixed structure.

In addition, in the figure, ₅₁ indicates that the rotating piece 5 uses the shaft 6 as a fulcrum.
When the door 3 rotates 90 degrees, it abuts a part of the receiving piece 2 and is integrated with the rotating piece 5, which prevents it from rotating any further. 8 is a folding piece that is integral with the rotating piece 5, which allows the door 3 to rotate 90 degrees using the pin 4 as a fulcrum. This is a stopper that comes into contact with a part of the bending piece ₅₁ to prevent it from rotating any further when it moves.

Next, the usage, operation, and effects of the device of the present invention will be explained with respect to the illustrated embodiment according to the above-described configuration of the present invention.

That is, when attempting to open the door 3 in the closed state of the door shown in FIG.
Since the door 3 cannot move while touching the edge of the door ₁ , the door 3 ends up rotating 90 degrees using the pivot 6 of the rotating piece 5 as a fulcrum as shown in FIG. When the door is rotated 90 degrees, the bending piece ₅₁ of the rotating piece 5 comes into contact with a part of the receiving piece 2, and further rotation is prevented, so when the door is further pushed in the opening direction, the door 3 is moved to the pin 4. Rotate using the fulcrum as a fulcrum and open it 180 degrees as shown in Figure 4.

When a force is applied to the door in the closing direction from this state, the door 3 rotates about the pin 4 and at the same time,
It rotates around the shaft 6 as a fulcrum to return to the original closed state, but depending on how the force is applied, the door's rotating piece 5
The rotating piece may rotate about the shaft 6 before it rotates relative to the shaft 6. In that case, the pin 7 of the door 3 comes into contact with the edge of the recess ₂₁ of the receiving piece 2 and prevents the rotating piece 5 from rotating about the shaft 6, so the door 3 rotates first using the pin as a fulcrum. and return to its original closed state without any problems. Thereafter, the above operation is repeated for each opening/closing operation.

As described above, according to the cabinet door hinge device according to the present invention, the door is of a two-axis rotation type and the width of the receiving piece that receives the bearing is the same as the thickness of the door, so that the door cannot be closed. In some cases, unlike conventional hinges, only the receiving piece or shaft portion does not protrude from the door surface and obstruct passage, and it also has a good appearance.
