SOLUTION: In this hinged door installing structure, one end base part of the hinged door body 3 is rotatably supported by a hinge 2, and one end base part side vertical end surface 4 of the hinged door body 3 is opposed to a hinged door side vertical end surface 5 of the vertical frame 1 of the opening part when closing the opening part by fitting the hinged door body 3 in the opening part. A damper 6 is installed between the vertical end surface 4 of the hinged door body 3 and the hinged door side vertical end surface 5 of the vertical frame 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention absorbs an impact generated when a hinged door is strongly closed, and is provided between an end face of the hinged door main body on the rotating shaft side and a vertical end face of the vertical frame of the opening on the hinged door side. The present invention relates to a structure for mounting a hinged door that eliminates finger jamming.

[0002]

2. Description of the Related Art A conventional door damper disclosed in Japanese Patent Application Laid-Open No. 2-279886 absorbs a collision impact by colliding the door damper with an oil damper mounted on a chamber wall when the door is opened. However, in this method, since the oil damper is projected from the chamber wall, the appearance is bad and there is a risk that the resident may accidentally get caught in the oil damper and get injured. Furthermore, this method has not solved the problem of finger stuffing between the end surface of the door on the rotating shaft side and the end surface of the opening on the door side. On the other hand, Japanese Patent Application Laid-Open No. 9-184354 discloses a hinge with a damper, but the damper portion of the hinge is not interposed between the end surface of the door on the rotating shaft side and the end surface of the opening, and There is a problem in that the damper portion of the hinge shaft portion has a large volume as compared with the hinge, and thus the appearance is not good. Further, conventionally, a door crower with a damper function has been provided between the upper part of the hinged door and the upper part of the opening, but this door crower has a problem that it is expensive and unattractive.

[0003]

SUMMARY OF THE INVENTION According to the present invention, a collision impact when a hinged door is closed can be well absorbed, and it is provided between an end face of the hinged door main body on the rotating shaft side and a vertical end face of the vertical frame of the opening on the hinged door side. It is an object of the present invention to provide a hinged door mounting structure that can be inexpensively mounted without damaging fingers, and since the state in which a damper is mounted is not conspicuous, the overall appearance is not spoiled.

[0004]

In order to solve the above problems, the inventions described in claims 1 to 5 take the following technical means. That is, according to the swing door mounting structure of the present invention, one end base portion of the swing door body is rotatably supported by a hinge in the vertical frame of the opening portion, and the swing door body is fitted into the opening portion so that the swing opening portion is opened. In a structure for mounting a hinged door such that a vertical end surface on one end base side of the hinged door main body faces a hinged door side vertical end surface of the vertical frame of the opening when closed, a vertical end surface of the hinged door main body and a hinged door side vertical direction of the vertical frame are provided. It is characterized in that a damper is attached between the end face and the end face.

The swing door mounting structure according to claim 2 is
By using the air damper as the damper, it is possible to reduce the cost, the maintenance and inspection are easy, and the opening and closing operation force of the hinged door is small compared with the case where the oil damper is used.

Further, in the hinged door mounting structure according to the third aspect of the present invention, the damper is mounted at substantially the same height as the position of the center of gravity of the hinged door main body, so that the damper can efficiently efficiently rotate the energy of the hinged door main body. It absorbs and the swing door body is less likely to be tilted or twisted by the reaction force of the damper.

Further, in the mounting structure for a hinged door according to a fourth aspect of the present invention, the damper is mounted on the vertical end surface of the hinged door body, and
The sliding protrusion of the damper is brought into contact with a contact portion provided on a vertical end surface of the vertical frame on the side of the hinged door so that the sliding protrusion is freely contactable with and separated from the vertical end surface of the vertical frame on the side of the hinged door. And the sliding projection of the damper is brought into contact with and separated from the contact portion provided on the vertical end surface of the hinged door body,
In particular, the damper and the abutting portion are less likely to be damaged and have a long life.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the hinged door mounting structure of the present invention according to claims 1 to 5 will be described below in more detail with reference to FIGS. 1 to 4. In the figure, reference numeral 1 is a vertical frame that constitutes a rectangular opening that can be opened and closed by a hinged door body 3. FIG. 2 shows a partially cutaway plan sectional view when the hinged door main body 3 is open. One of the vertical frames 1 facing each other of the opening is provided with a hinge 2 on one vertical frame 1. One end of the hinged door body 3 is rotatably supported. 9 is a door stop provided on the vertical frame 1 and 10 is a knob. A sliding projection 7 of a damper 6 projects inwardly and downwardly on a vertical end surface 4 of the hinged door body 3 on the one end base side (FIGS. 1 to 3), and when the hinged door body 3 is closed, the hinged door body 3 is opened. Fit in the department,
At this time, the sliding protrusion 7 of the damper 6 abuts on an abutting portion 8 made of a metal plate or the like mounted on the vertical frame 1 of the opening, and the sliding protrusion 7 is abutted by the abutting portion 8 so that the sliding door body 3
It is pushed so as to be substantially flush with the vertical end face 4 of the (FIG. 4).
At this time, the sliding protrusion 7 is stored in the storage recess 11 provided in the vertical end surface 4 of the hinged door body 3. The mounting height of the damper 6 is substantially the same as the position of the center of gravity G of the hinged door body 3 (FIG. 1).

The damper 6 is an air damper in the embodiment, and the sliding projection 7 of the damper 6 is connected to the piston 14 in the cylinder 13 via a shaft that slidably penetrates the lid 12. Piston 14 and cylinder 13
The return spring 15 is interposed between the return spring 15 and the bottom of the slide protrusion 7, and the sliding protrusion 7 is pushed against the return spring 15. Reference numeral 16 denotes an air hole penetrating the piston 14, and the left and right chambers partitioned by the piston 14 communicate with each other through the air hole 16. Reference numeral 17 is an air hole provided in the cylinder 13 so as to communicate with each of the left and right chambers, and 18 is an air hole communicating with the air holes 17, 17 and with the storage recess 12. When the sliding protrusion 7 is pushed in, the air in the left and right chambers partitioned by the piston 14 is compressed and expanded, and the air flows through the air holes 16, 17, and 18, respectively. In some cases, the air in the storage recess is also in the cylinder 13. Go in and out. The size of the air holes is appropriately determined according to the type of damper. The air holes 17 and 18 are not always necessary. The structure of the damper 6 is not limited, and a known damper is used.

In the illustrated example, the damper 6 is provided on the hinged door main body 3 and the abutting portion 8 with which the sliding projection 7 of the damper 6 abuts is provided on the vertical frame 1 of the opening, but their mounting positions are reversed. It may be (not shown). In short, the damper 6 includes the vertical end surface 4 of the hinged door body 3 and the vertical end surface 5 of the vertical frame 1 on the hinged door side.
It should be installed between and.
