Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hinge, and more particularly to a tightening hinge having a function of securely tightening a door or the like.

[0002]

[Prior art]

 Generally, in a building, the door is attached by rotatably supporting one side of the door 11 by a plurality of hinges 13 as shown in FIG.

Further, the handle 15 is used in a door that is conventionally required to be airtight such as an AT (Air Tiet) door used in an acoustic room, an air-conditioning machine room, etc., or a shield door used in a magnetic shield room, etc. In addition, the handlet airtightness has been improved by using a Gremont handle.

[0004]

[Problems to be solved by the device]

 However, in the conventional door mounting method, since one side of the door 11 is simply rotatably supported by the plurality of hinges 13, it is possible to sufficiently secure the airtightness of the door 11 on the hinge 13 side. There was a problem that it was difficult.

The present invention has been made to solve such a conventional problem, and is intended to provide a tightening hinge capable of significantly improving the airtightness of the hinge side of the door as compared with the conventional case. is there.

[0006]

[Means for Solving the Problems]

 In the tightening hinge according to the present invention, the door side mounting member is swingably arranged on one side of the hinge body via the door side hinge, and the frame side hinge is arranged on the other side of the hinge body. The frame-side mounting member is swingably disposed through the door-side hinge, and the door-side hinge is provided with a swing-limiting mechanism that limits the swing angle of the door-side mounting member with respect to the hinge main body. The hinge is provided with an urging mechanism for urging the hinge main body to rotate toward the frame-side mounting member.

[0007]

[Action]

 In the tightening hinge of the present invention, the frame-side hinge is provided with the urging mechanism for urging the hinge main body to rotate toward the frame-side mounting member, so that when the door is closed, the door-side hinge and the door-side mounting member are attached. The tightening hinge side of the door is constantly pressed via.

Further, since the swing restriction mechanism for limiting the swing angle of the door mounting member with respect to the hinge main body is provided on the door hinge, the door can be largely rotated around the door hinge when the door is opened. It will not move.

[0009]

【Example】

 The present invention will now be described in detail with reference to an embodiment shown in the drawings. FIG. 1 shows an embodiment of the fastening hinge of the present invention, and the reference numeral 21 denotes the hinge main body.

A door side attachment member 25 is swingably arranged on one side of the hinge main body 21 via a door side hinge 23. The door-side mounting member 25 has a T shape, and a mounting hole 25b is formed in the bottom surface portion 25a.

On the other side of the hinge main body 21, a frame side attachment member 29 is swingably arranged via a frame side hinge 27. The frame-side mounting member 29 has a T shape, and a mounting hole 29b is formed in the bottom surface portion 29a.

As shown in FIG. 2, the door-side hinge 23 has a piece portion 21 a formed on one side of the hinge main body 21 and a piece portion 25 c formed on the door-side mounting member 25 fitted therein, It is formed by inserting a hinge screw 31 into a through hole formed in the portions 21a and 25c and screwing a root portion of the hinge screw 31 into the piece portion 21a.

In this embodiment, the door-side hinge 23 is provided with a swing limiting mechanism that limits the swing angle of the door-side mounting member 25 with respect to the hinge main body 21. As shown in FIG. 3, this swing limiting mechanism includes a notch concave portion 21c formed on the lower side of the piece portion 21a of the hinge main body 21 and a notch convex portion formed on the piece portion 25c of the door side mounting member 25. It is formed by fitting 25d.

As shown in FIG. 4, the frame-side hinge 27 has a piece portion 21d formed on the other side of the hinge main body 21 and a piece portion 29c formed on the frame-side attachment member 29 fitted therein to form a piece. It is formed by inserting the hinge screw 33 into the through hole formed in the portions 21d and 29c and screwing the root portion of the hinge screw 33 into the piece portion 21d.

In this embodiment, the frame-side hinge 27 is provided with an urging mechanism that urges the hinge main body 21 to rotate toward the frame-side mounting member 29. This urging mechanism is formed by inserting the coil spring 35 into the through holes of the hinge body 21 and the frame portions 21d and 29c of the frame-side mounting member 29.

The tip of the coil spring 35 is locked to the lower part of the through hole of the piece 29 c, and the upper end of the coil spring 35 is locked to the lower side of the screw part 33 a of the hinge screw 33. .

The attachment of the door using the above-mentioned tightening hinge is performed by fixing the bottom portion 25a of the door side attachment member 25 of the tightening hinge 37 to the door 39 with a screw as shown in FIG. This is performed by fixing the bottom portion 29a of the side attachment member 29 to the frame body 41 with screws.

Thus, in the tightening hinge configured as described above, the door side attachment member 25 is swingably arranged on one side of the hinge main body 21 via the door side hinge 23, and A frame side mounting member 29 is swingably arranged on the other side of the number body 21 via a frame side hinge 27, and a swing angle of the door side mounting member 25 with respect to the hinge main body 21 is set on the door side hinge 23. Since the swing limiting mechanism for restricting is provided, and further, the frame side hinge 27 is provided with a biasing mechanism for rotationally biasing the hinge main body 21 toward the frame side attachment member 29 side, the hinge side of the door 39 is provided. The airtightness of can be greatly improved compared to the conventional one.

That is, in this tightening hinge, the frame-side hinge 27 is provided with the urging mechanism that urges the hinge main body 21 to rotate toward the frame-side mounting member 29, so that when the door 39 is closed, Since the fastening hinge side of the door 39 is constantly pressed via the door-side hinge 23 and the door-side mounting member 25, for example, the door 39 may always be in close contact with the seal member 43 formed on the frame body 41. Therefore, the airtightness of the hinge side of the door 39 can be significantly improved as compared with the conventional case.

Further, the door side hinge 23 is provided with the swing limiting mechanism for limiting the swing angle of the door side mounting member 25 with respect to the hinge main body 21, so that when the door 39 is opened, as shown in FIG. The door 39 is prevented from pivoting about the door side hinge 23 largely.

In this case, the swing angle θ of the door 39 is preferably set so that the tip of the door 39 rotates about 50 mm when the width of the door 39 is about 1000 mm, for example. In addition, in the embodiment described above, an example in which the door of the building is supported by the fastening hinge of the present invention has been described, but the present invention is not limited to such an embodiment and, for example, doors of various devices and the like. Of course, it can be widely used to support

[0022]

[Effect of device]

 As described above, according to the fastening hinge of the present invention, when the door is closed, the fastening hinge side of the door is always pressed by the hinge on the door side and the door side mounting member. This has the advantage that the airtightness of the can be significantly improved compared to the conventional one.
