Description

[Detailed description of the invention] The present invention provides a connecting cylindrical part 2 on one side of the hinge element 1, and connects the connecting cylindrical part 2 on the other side of the hinge element 1 so as to be at a different level from the connecting cylindrical part 2. A connecting cylindrical portion 3 is provided, and a connecting cylindrical portion 2 and a connected cylindrical portion 3 of the two hinge pieces thus formed are provided.
The hinge piece 1 is attached to the opposite end surfaces of the two door panels 4a and 4b so that the door panels 4a and 4b face each other, and the door panels 4a+
This relates to a bifold door in which a hinge pin 5 is removably inserted between a connecting cylindrical part 2 and a connected cylindrical part 3 located on either the front side A or the back side B of 4b. And,
The purpose is to provide a bi-folding door that can be installed left-handed or left-handed, even if the door is of the same type, by simply replacing the hinge pins.

The present invention will be explained in detail below with reference to Examples.

A connecting cylindrical part 2 is provided in the center of one side of the hinge element 1 having an appropriate number of mounting holes 6, and a connecting cylindrical part 2 is provided above and below the other end of the hinge element 1. The cylindrical parts 3 and 3 for connection are provided at different levels, and a hinge pin 5 is provided between the cylindrical part 2 for connection and the cylindrical part 3 for connection of the two hinge pieces 1. By inserting the , the two hinge pieces can be rotatably hinged.

Furthermore, a moving runner 7 is attached to the upper end of one door panel 4a, a guide pin 8 is attached to the lower part, and a fixed hanging bracket 9 is attached to the upper end of the other door panel 4b. A pivot 15 is attached to the lower part.

The end faces of these two door panels 4a, 4b without the movable runner 7 or the fixed hanging fittings 9 are made to face each other, and the connecting cylindrical part 2 and the connected cylindrical part 3 of the two hinge pieces 1 are made to face each other. Two hinge pieces 1 are attached to two door panels 4a so as to face each other,
A hinge pin 5 is attached to each end face of the door panel 4b, and a hinge pin 5 is installed between the connecting cylindrical part 2 and the connected cylindrical part 3 located on any one of the front side A to the back side B of the door panels 4a and 4b. It is inserted removably and assembled into a bi-fold door.

Here, 10 in the figure is a washer for smoothing the hinge.

Then, the moving runner 7 is rolled onto the upper rail 11, the guide pin 8 is slidably inserted into the lower rail 12, and the fixed hanging bracket 9 is rotatably attached to one end of the upper rail 11 to the lower-waist rail 12. The pivot 15 is rotatably mounted.

In the figure, 13 is a door stop of the upper rail 11, and 14 is a stopper.

The bifold door is installed in this manner, and the opening can be opened and closed by operating the door panel 4a.

If the bifold door is installed right-handed, the door panel 4a is placed on the left side and the door panel 4b is placed on the right side, and the connecting cylindrical shape is placed on the back side B of the door panels 4a and 4b as shown in Figures 5a and 5b. A hinge pin 5 is inserted between the portion 2 and the cylindrical portion 3 to be connected.

Then, the doors can be opened in the order shown in FIG. 6a, b, and c.

When installing a bifold door on the left, use door panel 4a.
on the right side and the door panel 4b on the left side, as shown in Fig. 7a.
, b, the hinge pin 5 is inserted between the connecting cylindrical part 2 and the connected cylindrical part 3 located on the front side A of the door panel 4at4b.

Then, the doors can be opened to the left in the order shown in Figure 8 a, b, and c.

As described above, the present invention provides a connecting cylindrical part on one side of the hinge element, and a connected cylindrical part on the other side of the hinge element so as to be at a different level from the connecting cylindrical part. The hinge pieces are respectively attached to the opposite end surfaces of the two door panels so that the connecting cylindrical part and the connected cylindrical part of the two hinge pieces formed as shown in FIG. Since the hinge pin is removably inserted between the connecting cylindrical part and the connected cylindrical part located on either the back side of the door panel, the hinge pin can be inserted from the front side of the door panel to the back side, or You can freely form the hinge part on the front or back side of the door panel by simply replacing it from the back side to the front side. By simply replacing the hinge, you can easily move only the hinge part of the hinge and change the folding direction of the door panels, which has the advantage of being able to be installed either left-handed or right-handed with the same product.
In addition, the position of the hinge can be changed simply by replacing the hinge pin, so even if the hinge is moved, there will be no screw holes left on the door panel, which will not damage the appearance of the door panel, and will not damage the appearance of the door panel. Even if the folding direction is changed, the positional relationship between the door panels does not change before and after the change, and there is no problem in opening and closing the door.

Furthermore, a hinge can be formed by combining hinge pieces of the same shape, and by simply attaching hinge pieces of the same shape to a door panel, it can be used for left and right hands. It only needs to be manufactured, and has the advantage of being easy to manufacture and low in cost.
