Abstract

PROBLEM TO BE SOLVED: To provide a new folding door having a function, in which the same opening section as a conventional folding door composed of left-right door panels having the same width can be secured, through the width of one door panel is formed shorter than that of the other door panel. SOLUTION: In the folding door A, in which two door panels 1, 2 having different width are connected foldably through a hinge member B and the other end section of at least the door panel 1 having short width is pivoted movably to a travelling body 9 travelling along a rail 8, the hinge member B is constituted of fitting pieces 3, 3 fixed at adjacent edge sections of each door panel 1, 2, connecting arms 5, 6 in specified length rotatably extended through vertical pivot shafts 4 from the mounting pieces and a shaft section 7 rotatably coupling the front ends of these connecting arms.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door type or sliding door type folding door.

[0002]

2. Description of the Related Art In general, a folding door is formed by two door plates of the same width which are symmetrically connected to each other at a central portion by a hinge. However, in recent years, with the diversification of consumer preferences, there has been a desire for a folding door design composed of door plates of different widths. However, if one door plate is shorter than the other door plate, there is a problem in that when folded, the shape becomes a shape in plan view and the opening is largely obstructed.

[0003]

SUMMARY OF THE INVENTION Therefore, the present invention is to secure the same opening as a conventional folding door having left and right door plates of the same width, while one door plate is formed shorter in width than the other door plate. The main purpose of the present invention is to provide a new folding door having a function capable of performing the following.

[0004]

In order to achieve the above object, the present invention takes the following technical measures. That is, in the folding door according to the present invention, two door plates 1 having different widths,
2 is hingedly connected via a hinge member B, and at least the other end of the door plate 1 having a short width is rotatably supported by a traveling body 9 traveling along a rail 8.
The hinge members B are fixed to the adjacent edges of the respective door plates 1 and 2 with mounting pieces 3 and 3 and a vertical pivot 4
And connecting arms 5 and 6 of a predetermined length that are rotatably extended through the shaft, and a rotating shaft 7 that rotatably connects the tips of these connecting arms.

When the connecting arms 5 and 6 are extended in a straight line, they are formed so that the sum of the widths of the connecting arms 5 and 6 and the short width door plate 1 is the same as the width dimension of the long width door plate 2. Have been. As a result, it can be folded in the same manner as a conventional folding door having left and right door plates having the same width, and a large opening can be secured.

The two connecting arms 5 of the hinge member B,
It is preferable that one of the six is formed shorter than the other. Thereby, when the folding door A is closed linearly, the two connecting arms 5, 6 are folded toward the shorter connecting arm 5 so as to be close to the door plate surface and can be prevented from protruding forward.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A folding door according to the present invention will be described below with reference to the embodiment shown in FIGS. In the figure, reference numeral A denotes a folding door according to the present invention, in which two door plates 1 and 2 having different widths are foldably connected via a hinge member B. The other end of each of the door plates 1 and 2 is rotatably supported by traveling bodies 9 and 9 traveling along a rail 8.
In the present embodiment, the traveling body 9 is formed of a roller and is hung on the rail 8 so as to be able to travel freely. However, the traveling body 9 may be formed to simply travel along the rail like a sliding door.

[0008] The hinge member B is rotatably extended from the mounting pieces 3, 3 via a vertical pivot 4, and mounting pieces 3, 3 fixed to adjacent edges of the door plates 1, 2. It is provided with connecting arms 5 and 6 having a predetermined length and a rotating shaft portion 7 for rotatably connecting the tips of these connecting arms.

As shown in the imaginary line of FIG. 1 and in FIG. 2, the connecting arms 5 and 6 are folded when the connecting arms are extended in a straight line. Are formed so that the sum of the widths thereof is the same as the width of the long door plate 2. Accordingly, the left and right door plates 1 and 2 can be folded at the same inclination angle in the folding posture of FIG. 2 in the same manner as the conventional folding door having the same width on the left and right, and a wide opening can be secured.

In this embodiment, one of the two connecting arms 5, 6 of the hinge member B is formed shorter than the other. Thus, when the folding door A is closed linearly as shown in FIGS. 1 and 3, the two connecting arms 5 and 6 are folded toward the shorter connecting arm 5 so as to approach the door plate surface, Protruding forward can be avoided.

Usually, two hinge members B are provided above and below the door plates 1 and 2, but may be more than two.

Although one embodiment of the present invention has been described above, the present invention is not necessarily limited to the structure of the embodiment. For example, in the above-described embodiment, one end of the long width door plate 2 is supported by the traveling body 9, but may be directly rotatably held on the rail 8. Also, the traveling body 9 may be formed in a slippery form such as a sled instead of a roller. In addition, the present invention can be carried out by appropriately modifying it within the scope having the constituent features, achieving the object of the present invention, and achieving the following effects.

[0013]

Since the folding door of the present invention is constructed as described above, the width of one door plate is shorter than that of the other door plate. Like Orito made of doorboards,
There is an effect that the left and right door plates can be folded at the same inclination angle in a good appearance, and thereby a wide opening can be secured.
