Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a folding door, and more particularly to a folding door device that can be easily installed without closing a finger that has entered a gap in a joint when the folding door is closed.
[0002]
[Prior art]
The folding door can be bent through the joint, and the frontage can be opened or closed. However, if the folding door closes as it is when the folding door is closed when the folding door is folded, the joint opening is also closed. A finger is pinched by this. In view of this, various structures have been used in the past in order to prevent finger folding at the folding door.
[0003]
6 (a) to 6 (c) show a joint part of a folding door using a conventional finger-proofing prevention structure. The folding door of (a) has two panels (A) and (B). It is connected with a hinge (c) and folded, but as shown in the same figure, the space (d) remains even when both panels (a) and (b) are extended and the frontage is closed. Fingers are never stuffed. In the case of the folding door (b), there is a space (d) between the panels (A) and (B) in the closed state.
[0004]
The folding door shown in (c) is attached to gears (e) and (e) meshing with the side edges of the panels (a) and (b) and hung on the centers of the gears (e) and (e). It is connected by a connecting plate (f). Accordingly, the panels (A) and (B) can be bent with the centers of both gears (E) and (E) as axes. Accordingly, there is no gap between the panels (A) and (B) for fitting a finger, and it is not necessary to prevent finger filling.
[0005]
As described above, various measures have been devised in the past to prevent finger folding at the folding door, but such a structure impairs the appearance of the folding door. In addition, in the case of FIGS. 6 (a) and 6 (b), there still remains a problem that light leaks from the gap between the panels (a) and (b) to which the joint hinge (c) is attached. In the case of (c), the gears (e) and (e) must be used, which complicates the structure as a folding door.
[0006]
Folding doors have the same size for both panels (a) and (b), and a shaft is provided above and below one side of the suspension side panel. A slider is provided, and when the folding door is opened and closed, the suspension wheel and the slider can move along the rail. Therefore, because the structure is supported at the panel side end, if the panel becomes large, a large load is applied to the suspension side shaft and the suspension car, and the entire folding door device is loose, which hinders the opening and closing operation of the folding door. .
[0007]
Conventionally, when the side end of the suspension side panel is pivotally supported, the lower end of the panel must be fitted to the shaft provided on the floor, and the shaft must be inserted from the upper surface of the upper rail and fitted into the shaft hole at the upper end of the panel. The installation work is very troublesome. One door-end side panel is suspended from a suspension bolt that extends downward from a suspension vehicle mounted on the upper rail, and is connected to the suspension-side panel by a hinge. Of course, the suspension side panel and the door end side panel may be connected to each other before being mounted on the rail, but this is inconvenient in the conventional support structure on the suspension side.
[0008]
[Problems to be solved by the present invention]
Thus, the conventional folding door apparatus has the above-mentioned problems. The problem to be solved by the present invention is this problem, and provides a structure that can prevent finger filling with a simple structure without impairing the appearance. At the same time, it is possible to provide a folding door device that prevents light leakage from the joint portion and that can be easily attached to the folding door.
[0009]
[Means for Solving the Problems]
In the folding door of the present invention, two panels are connected via hinges, each panel is bent around the hinge, and the frontage is opened and closed. The suspension side panel can be rotated (turned) supported by hinges provided at the upper and lower ends of the panel, and the other door side panel is suspended from the suspension wheel. The hinge may be provided on the upper rail and the floor surface. And this suspension vehicle can move on the upper rail provided in the upper part of the frontage, and the panel is rotatably suspended by suspension bolts extending downward from the suspension vehicle. The folding door device of the present invention does not have a lower rail.
[0010]
A hinge piece of a hinge is attached to the panel side end that becomes the joint part, and the vertical beam of the portion where the butterfly piece is not joined has a recessed side edge surface, and a cushion material is attached to the bottom of the panel recess on one side . The cushion material is sized and shaped so that when the folding door is closed, the side edge can come into contact with the bottom of the recess of another panel. And both the hinge pieces of the hinge are so that a certain amount of space is left when the folding door is closed, that is, it is not pinched by both butterfly pieces even when a finger is fitted between the two butterfly pieces. Yes.
[0011]
Then, the upper rail and a part of the upper rail side of the upper rail are cut out so that the upper hinge or the hinge receiver can be attached from the front side so that the suspension side panel can be easily supported. The upper hinge is fixed to the metal fitting, and the metal fitting is inserted from the notch portion of the upper rail and screwed. Of course, the lower hinge is provided on the floor as in the prior art. When the hinge is provided on the panel side, only the hinge receiver is screwed. Of course, the inspection panel is attached and covered so that the notched portion is not exposed to the outside, and the inspection panel is attached to the upper rail. Furthermore, when the folding door is closed, the door stop is not exposed to the outside, and is configured to fit within the upper rail.
[0012]
