Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a folding door that can be folded into a small zigzag shape when not in use.

[Background technology]

In conventional folding doors, a handle separate from the spacer is attached within the hinge frame between the upper and lower spacers. Therefore, the spacer must be separated into upper and lower parts, which increases the number of parts and takes time to assemble.Also, if you try to increase the mounting strength of the handle, it becomes complicated to assemble the handle, and if you simplify the assembly structure, it will come off. I was afraid.

[Purpose of the invention] The present invention was made in view of the drawbacks of the conventional example described above, and its purpose is to reduce the number of parts and improve ease of assembly by integrating the handle and the spacer. To provide a folding door which can increase the mounting strength of a handle part with a simple structure.

[Disclosure of invention]

The present invention has openings 1 on both side edges of a hinge frame 2 having a substantially C-shaped cross section and having an opening 1 along its entire length.
A shaft portion 3 is provided between the two, and a hinge arm 5 having a substantially C-shaped cross section is provided protruding from the side edge of the door panel body 4.
Each hinge arm 5 of the adjacent door panel body 4
is inserted into the hinge frame 2 through the opening 1 and rotatably locked on the outer periphery of the shaft portion 3, and the hinge frame 2
The spacer 6 is inserted over almost the entire length into the hinge frame 2, and the spacer 6 is brought into contact with the inner surface of the hinge frame 2 and slidably contacted with the outer peripheral surface of the hinge arm 5, and the handle portion 7 formed integrally with the spacer 6 is attached to the hinge. The present invention relates to a folding door that projects from between the arms 5 to the outside of the hinge frame 2, thereby achieving the above object.

The present invention will be explained in detail below with reference to the accompanying drawings. 2 is a hollow hinge frame made of aluminum or the like;
It is formed into a substantially C-shaped cross section, and is provided with an opening 1 over the entire length of the top and bottom of one side, and approximately cylindrical holes are provided on both side edges of the hinge frame 2, sandwiching the opening 1, over the entire length of the top and bottom, respectively. A shaft portion 3 is provided. The inner diameter of the shaft portion 3 is a tapping hole. Reference numeral 4 denotes a plurality of door panel bodies to be connected to form the folding door A, and from the end cover 8 attached to the side end surface of the door panel body 4, the cross section is approximately C-shaped over the entire vertical length. The hinge arm 5 of is made to protrude. However, the adjacent door panel element 4
The respective hinge arms 5 are inserted into the hinge frame 2 through the opening 1, and the hinge arms 5 are rotatably locked to the outer periphery of the shaft portion 3, and the adjacent door panel bodies 4 are
The members are hinged together so that they can rotate freely, and the door panel element 4 is connected to the hinge frame 2 as shown in Figure 2.
It is designed to be folded in a zigzag pattern. In addition, in order to insert the hinge frame 5 into the hinge frame 2, it may be inserted through the opening 1 due to the size, or the hinge arm 5 may be slid from the upper end of the hinge frame 2. 6
is a hollow spacer (it does not matter if it is solid), and is inserted over the entire length of the upper and lower parts of the hinge frame 2, and is brought into contact with the inner surface of the hinge frame 2 and the hinge arm 5. This prevents the hinge arm 5 from coming off or rattling, allowing the folding door A to be opened and closed smoothly. Further, the openings at the upper and lower ends of the hinge frame 2 are closed by caps (not shown).

As shown in FIG. 1, the folding door A constructed in this way is suspended between the upper and lower rails 11 and 12 by runners 9 and slide shafts 10 provided on every other hinge frame 2. It's lowered. A handle part 7 is integrally formed with the spacer 6 at the end over the entire length, and the handle part 7 is connected to the hinge frame 2 from between the hinge arms 5.
It is made to protrude outside. Therefore, this handle portion 7 serves as a handle to be pulled when closing the folding door A, and can be operated with a single touch. And the elastic material 13 at the end of the folding door A
is designed to fit into the groove 14 of the door stop and be closed without any gaps.

[Effect of idea]

Since the present invention is constructed as described above, the spacer can prevent the hinge arm from wobbling, and the spacer and handle can be assembled into the hinge frame at the same time, making assembly easy. , there is an advantage that the number of parts is also reduced. Furthermore, since the handle part is integrated with the spacer inserted over its entire length into the hinge frame, no separate means for fixing the handle part is required.
Moreover, there is an advantage that the attachment strength of the handle portion can be increased with a simple structure. Moreover, since the spacer is brought into contact with the inner surface of the hinge frame and is also brought into sliding contact with the outer peripheral surface of the hinge arm, the spacer is in contact with the inner surface of the hinge frame and the outer peripheral surface of the hinge arm. This prevents the spacer from moving inward of the hinge frame when the hinge arm rotates when the panel is folded, and the spacer follows the inward movement of the hinge frame. There is no fear that the handle part will be drawn in between the hinge arms and the fingers gripping the handle part will get caught between the hinge arms, and the panel can be folded by grasping the handle part without the problem of jamming the fingers. It is something.
