Description

[Detailed Description of the Invention] The present invention relates to an opening/closing device such as a shutter for a house, a hinged door for a warehouse or a factory, or a door for furniture.

For example, when the shutters of a house do not have a door pocket, one end of the shutter is pivoted and the shutters are rotated to open, but when there are three or more shutters, all of the shutters must be opened. As shown in Figs. 1 and 2, an intermediate shutter 1 is connected via a hinge 4 to the shutters 3 on both sides, whose one end is pivotally supported by a support shaft 2 on the upper and lower shutter frames. In order to open and close the shutter 1 together with the shutters 3 on both sides, and to support the weight of the intermediate shutter 1, rollers 5 and the like are protruded from the upper and lower parts of the other end of the intermediate shutter 1 relative to the hinge 4 side. This roller 5 is engaged with a groove-shaped rail 6 provided in the upper and lower shutter frames.

In this case, in order to completely open the shutter 1°3 by rotating the shutter 3 approximately 180 degrees, as shown in Fig.
The width of the shutter must be wider than the width of the shutters 3 on both sides, and the fact that the dimensions of the shutters 1 and 3 are different in the two products even though they have the same shape will hinder standardization in processing and manufacturing. This also makes managing the parts complicated.

Also, without changing the width of shutters 1 and 3, the width of shutters 1 and 3 can be changed to approximately 180 mm.
In order to rotate, as shown in Figure 2, a turntable 7 is provided protruding from both ends of the upper and lower shutter frames, and this turntable 7 has an arc-shaped rail that is an extension of the rail 6 of the shutter frame. 8, the number of parts increases, processing becomes complicated, and the turntable 7 has to be installed.
This is not desirable from the appearance point of view as it protrudes.

The present invention was developed in view of these points, and it is possible to reduce the width by approximately 18 cm as described above without changing the width of the opening/closing body such as a storm door.
This realizes an opening angle of 0 degrees.

Next, one embodiment of the present invention will be described based on the drawings.

In FIG. 3, reference numeral 11 denotes a shutter on both sides as a first opening/closing body, and one outer end of the shutter 11 is rotatably supported on an upper and lower shutter frame (not shown) by a support shaft 12. At the same time, one outer end of an intermediate shutter 13 serving as a second opening/closing body is connected to the other inner end via a hinge 14.

The intermediate shutter 13 has guides 15 made of rollers or pins protruding from the top and bottom of the other inner end, and these guides 15 are shaped like grooves provided linearly in the upper and lower shutter frames. The support shaft 1 is engaged with the guide rails 16 of
2, the intermediate shutter 13 moves along the guide rail 16 toward the support shafts 12 of the shutters 11 on both sides, and then bends at the hinge 14, and these shutters 1
1. Bend approximately 180 degrees from 13 degrees until they become parallel.

In this case, in order to completely open the shutter 11.13 by rotating the shutter 11 approximately 180 degrees as shown in the opening in FIG. 3, the conventional method shown in FIGS. It is necessary to change the width of the shutter 13 or install a turntable, but in the present invention, without doing these things, the mounting structure of the hinge 14 allows the shutters 11 and 13 to rotate approximately 180 degrees. There is.

That is, as shown in FIGS. 4 to 6, the hinge 14 has a pair of long and short mounting pieces 22 connected to the rotation center axis 21.
．． 23 are rotatably connected to each other, the tip of the longer mounting piece 22 is bent into a crank shape, and a rotation center shaft 21 is attached to the tip of the long mounting piece 22 as shown in FIGS. 4 and 6. When each mounting piece 22, 23 is bent and made parallel to the center, a mounting part 24 is formed which is located on the same plane as the shorter mounting piece 23, and this mounting part 24 and the above-mentioned shorter mounting part 24 are Piece 2
3 has a mounting hole 25 bored therein as shown in FIG.

As shown in FIG. 4, the hinge 14 has its shorter mounting pieces 23 attached to the other ends of the storm shutters 11 on both sides through mounting holes 25 with screws 26.
With the mounting pieces 22 and 23 in parallel, the mounting part 24 of the longer mounting piece 22 is attached to one end of the intermediate shutter 13 through the mounting hole 25 with a screw 26, and its rotation center The shaft 21 extends from the other end of the shutter 11 on both sides to the shutter 11.
It is attached to each of the shutters 11 and 13 with an offset toward the support shaft 12 at one end of the shutter.

Therefore, when the shutters 11 on both sides are rotated from the state shown in FIG.
As a result, as shown in FIG. 3 and FIG. 5, a situation similar to that of changing the width of the shutters 11 and 13 occurs.

Therefore, without changing the width of shutters 11 and 13,
Moreover, without providing a turntable, the shutter 11.
13 can be fully opened with an opening angle of approximately 180 degrees.

As described above, according to the present invention, the first opening/closing body is connected to the second opening/closing body.
Since the support shaft of the hinge that connects the first opening and closing body to the first opening and closing body is deviated in the direction of the pivot of the first opening and closing body, the same effect as changing the width of each opening and closing body can be obtained without changing the width of each opening and closing body. As a result, the opening/closing bodies can be completely opened at an opening angle of approximately 180 degrees without changing the width of each opening/closing body or without providing a turntable, etc., and therefore, without increasing the number of parts. This makes it possible to standardize the processing and manufacturing of the opening/closing body, and also improves the appearance.
