Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinged door device used at a gate of a school or a factory, and more particularly to a hinged door device which can be stored compactly.

[0002]

2. Description of the Related Art Conventionally, a hinged door is used by opening and closing the hinged door in a fan shape having a radius equal to the length of the hinged door. For this reason, when the hinged door is opened, a space corresponding to the length of the hinged door is required to keep the hinged door open, which causes a problem that the installation of the hinged door requires a large installation area.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a hinged door which requires a small area for opening and closing the hinged door, can store the hinged door compactly, and can reduce the installation area.

[0004]

According to the present invention, there is provided a hinged door apparatus having a hinged door, and a support fixed to a support surface and rotatably supporting the hinged door. A hinged door body connected to the support, and a folded body connected to the hinged door body via hinge connecting means, wherein the bent body overlaps a side surface of the hinged door body around the hinge connecting means. The above object has been achieved by providing a hinged door device characterized by being foldable.

FIG. 1 is a perspective view of a hinged door device according to the present invention.
It is a front view showing an embodiment. FIG. 2 is a partially enlarged view showing a connecting portion between a hinged door main body and a bent body in the hinged door device shown in FIG. 1. FIG. 3 is a perspective view showing a state in which the folded body in the hinged door device shown in FIG. 1 is being folded. FIG. 4 is an enlarged top view showing a state in which the folded body in the hinged door device shown in FIG. 1 is completely folded and fixed with a stopper. FIG. 5 is a plan view illustrating a turning process of the hinged door body in the hinged door device illustrated in FIG. 1.

As shown in FIGS. 1 to 3, a swing door device A of this embodiment is used as a gate, and is fixed to a swing door B and a support surface D so that the swing door A can be freely rotated. And a support C supported by the support member.

In the swing door apparatus A of the present embodiment, the swing door B is, as shown in FIGS. 1 to 3, a swing door body 1 connected to the support C, and hinge connecting means E connected to the swing door body 1. And a bent body 1a connected through the hinge connecting means E.
And can be folded so as to overlap with the side surface of the door body 1.

More specifically, the hinge connecting means E
Is a hinge 4 in the present embodiment, as shown in FIG. As the hinge 4, a conventionally known hinge can be used without any particular limitation.

As shown in FIG. 2, the bent body 1a is connected to the leading end of the hinged door main body 1. The hinged door main body 1 and the bent body 1a are connected to frame bodies 11 and 11a, respectively. It is provided. Further, the hinged door body 1 and the bent body 1a are respectively connected to the frame 1
1 and 11a, and vertical lattices 12 and 12a arranged at predetermined intervals inside the frame bodies 11 and 11a.

In the connecting portions of the hinged door main body 1 and the bent body 1a, both frame bodies 11, 11a are respectively provided with through holes 2, 2a formed so that the holes are continuous and linear. Then, a fixing tool 5 having a pin 51 having a length that loosely engages with the through holes 2 and 2a and penetrates between adjacent frames can be mounted. That is, the fixing tool 5 has a U-shape and includes the two pins 51 and a connecting piece 52 connecting the pins 51. Further, two fixtures 5 are provided at the upper part and the lower part of the hinged door B.

As shown in FIG. 4, in the case of the hinged door device A of this embodiment, when the folded body 1a is folded, a stopper 6 for holding the hinged door body 1 and the folded body 1a together is provided. Have. The stopper 6 has a shape having two concave portions in an E-shape so that the hinged door main body 1 and the bent body 1a can be collectively clamped above the hinged door B.

The hinged door device A of the present embodiment is used as follows.

That is, as shown in FIG. 2, when the gate is closed, the hinged door body 1 and the folded body 1a are connected by the hinge 4 and are unstable. 1a is fixed. Fixture 5
Is used so that the pin 51 is inserted into both the through holes 2 and 2a.

When the gate is released, the fixture 5 is pulled out from at least the through hole 2a as shown in FIG. Next, the bent body 1a is rotated about the hinge 4 in the direction indicated by the arrow X in FIG.
Layer on. That is, the frame 11 a is overlaid on the frame 11.
Further, the gate can be opened by rotating the hinged door body 1 about the support C in a state where the folded body 1a is folded in the direction indicated by the arrow Y in FIG. Here, since the bent body 1a is rotatable about the hinge 4 and is in an unstable state, it is fixed by the stopper 6.

The hinged door device A of the present embodiment is configured as described above and can be used in this manner, so that the hinged door can be opened and closed in a compactly housed state, and the installation area is small. It is a thing. In the case where the fixing device 5 is provided, the hinged door main body 1 and the folded body 1
a and firmly fixed in a linearly connected state,
When the gate can be closed smoothly and the stopper 6 is provided, the gate can be opened and closed smoothly by firmly fixing the gate in the folded state. Since opening can be performed, when the fixing tool 5 and the stopper 6 are provided, operability and safety are excellent.

Incidentally, the hinged door device of the present invention is not limited to the above embodiment, and can be variously modified without departing from the gist of the present invention.

For example, although the fixing devices 5 are provided at two locations above and below, one or three or more fixing devices may be provided depending on the size and weight of the hinged door.

The shape of the stopper 6 may be a U-shape or the like.

Further, when the length of the hinged door B is long,
One or more support rollers may be attached to the lower part of the frame body 1 or 1a at one or both ends of the hinged door B to support the weight of the hinged door B.

Further, the configuration of the hinged door device is not particularly limited.
In addition to the case of being configured with one hinged door, it may be combined with another door device such as a sliding door device.

Further, in the above-described embodiment, one folded body has been described as an example. However, another folded body is provided with a similar structure on the tip side of the folded body in the above-described embodiment. And two or more folded bodies may be connected.

[0022]

As described above, the hinged door device of the present invention requires a small area for opening and closing the hinged door, can store the hinged door compactly, and requires a small installation area.
