Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a folding door, and particularly to a bifold type folding door composed of a pair of door panels.

[Background technology]

In the above-mentioned folding door, each door panel is connected by placing a connecting frame between the door panel whose one end is pivotally supported and can freely rotate, and the door panel whose one end can freely run along the rail. There is one in which the other end is rotatably connected to the connecting frame, but in the past, the connection between the connecting frame and each door panel could only be rotated, and the door panel could not be moved up or down with respect to the connecting frame. I had learned not to slide around. Therefore, due to this, when the upper and lower frames of the opening of a house where a folding door is installed are tilted, the folding door must also be installed tilted in order to be folded.

[Purpose of the invention]

The present invention has been made in view of the above points, and it is an object of the present invention to provide a folding door that can be folded smoothly while keeping each door panel vertical even if the upper and lower frames of the opening are tilted. It is something.

[Disclosure of the invention]

The present invention provides that, in addition to rotatably connecting both door panels to a connecting panel, both door panels are individually connected to a connecting frame in a vertically movable manner, and that the range of vertical movement is regulated. This is the summary. With this configuration, when the upper and lower frames of the opening are tilted, both door panels are placed at different levels across the connecting frame, and the amount of this level difference changes as the door is folded. When both door panels are extended, the height difference is large, but when folded, the height difference decreases with this movement.Also, by regulating the vertical movement range, it is easier to handle during construction. It is an improved version of

Next, the present invention will be briefly explained based on the illustrated embodiment. In the figure, reference numerals 1 and 2 are door panels, and a runner 6 is located at the upper end of one side of one door panel 1, and a shaft 7 is located at the lower end of the door panel 1. protrudes, and the other end of the door panel 1 is rotatably connected to the connecting frame 3. The other door 2 also has a runner 6 at the upper end of one side end, a shaft 7 at the lower end, and is rotatably connected to the connecting frame 3 at the other end. The shaft 7 of the door 1 is supported by a bearing block 8 fixed in the lower rail 5 installed in the lower frame of the opening, so that the door panel 1 is supported rotatably at one end. This is what has been done. 4 is the upper rail on which the runner 6 is placed, and both door panels 1 and 2
is suspended from the upper rail 4 via runners 6, 6. The other door panel 2 has a runner 6 running on the upper rail 4 and a shaft 7 running on the lower rail 5, so that one end can run freely along the upper and lower rails 4 and 5. With these configurations, both door panels 1 and 2 can be folded. 9 is a latch, and 10 is a lock bar operated by a handle 11 provided on the connecting frame 3.

The connection of each door panel 1, 2 to the connection frame 3 is performed by the second
As is clear from the figures and FIG. 3, a connecting member 13 extending over the entire length of the upper and lower sides is attached to the side end surface of each door panel 1, 2, and a connecting piece 14 provided except for the upper end of this connecting member 13 is connected. A pair of cylinder shaft portions 1 in the frame 3
5, each door panel 1, 2 can be freely rotated with respect to the connecting frame 3.
Incidentally, since the latch holder 16 is attached to the upper end of the connecting frame 3, the total length of the connecting piece 14 is shorter than the entire length of the connecting member 13 by the vertical dimension of the latch holder 16. 17 is a spacer, 18 is an end plate fixed to the lower end of the connection frame 3, the latch holder 16 and the end plate 18
is a tapping screw 19 on the cylindrical shaft portion 15 of the connecting frame 3.
It is fixed by screwing it in.

In order to make each door panel 1, 2 vertically movable with respect to the connecting frame 3, in this embodiment, the vertical dimension of the connecting frame 3 is set to the vertical dimension of both door panels 1, 2, that is, the connecting member 13. It is longer than the top and bottom dimensions. Due to the fitting connection structure between the door panels 1, 2 and the connecting frame 3 as described above, both the door panels 1, 2 can each freely move up and down with respect to the connecting frame 3 by the difference l between the two dimensions. It is something that exists.

However, even if the upper and lower rails 4 and 5, which are the upper and lower frames of the opening, are tilted by an angle θ as shown in FIG. When the upper end comes into contact with the lower surface of the latch holder 16, the other door panel 2 moves downward relative to the connecting frame 3 which is at the same height as this door panel 1, and both door panels 1 and 2 are brought into the opening. It can be stored while maintaining its vertical state, and when folded, the door panel 2 moves upward relative to the connecting frame 3 according to the inclination of the upper and lower rails 4 and 5, and as shown in Fig. 4b, both doors Panels 1 and 2 are kept vertical.

In addition, when installing the door panels 1, 2 and the connecting frame 3 in the opening, the vertical movement range of each door panel 1, 2 with respect to the connecting frame 3 is limited to the latch holder 16 and the end plate 18 as described above. This prevents the door panels 1 and 2 and the connecting frame 3 from coming off each other.
This makes construction easier. Furthermore, this folding door can be selected between right-hand and left-hand depending on whether the bearing block 8 is installed on the left or right, but the inclination of the upper and lower rails 4 and 5 has nothing to do with this hand. be. In other words, the fourth
As shown in the figure, if the right side in the figure is higher, there is no problem even if you use door 2 as the hanging source and fold it as door panel 1 moves, and always both door panels 1 and 2. becomes vertical.

〔Effect of the invention〕

As described above, in the present invention, even when the upper and lower frames of the opening are tilted, both door panels can be opened and closed smoothly by maintaining the vertical state, and at this time, both doors can be opened and closed smoothly with respect to the connecting frame. Since each panel can move up and down individually, no matter which direction the upper and lower frames of the opening are tilted, the vertical deviation due to this tilt is within the vertical movement range of each door panel with respect to the connecting frame. Since the vertical movement range of both door panels relative to the connecting frame is regulated, even if both door panels are installed in the opening, both door panels and the connecting frame can be opened and closed smoothly. There is no possibility of them coming off each other, and therefore construction is easy.
