Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pivot hinge for rotatably supporting a door of a building.

[0002]

2. Description of the Related Art It is a well-known fact that pivot hinges have conventionally been used to rotatably support a building door.

A pivot hinge supports a door rotatably with respect to a building, and includes a door-side pivot member and a building-side pivot member. The pivot of the pivot member attached to the building is attached to the door. The pivot member is fitted into a hole of a bearing member, and the door is rotatably supported around a vertical axis.

[0004] Although it is clear that the door supported by such a pivot hinge is rotatable, it does not have a function for setting the maximum opening angle of the door.

[0005]

SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention to provide a pivot hinge having a function of setting a maximum opening angle of a door in the pivot hinge itself.

[0006]

According to the present invention, there is provided a pivot member attached to a building,
A pivot hinge comprising a pivot member attached to the door side, wherein a shaft of the building-side pivot member is fitted into a hole of a bearing member of the door-side pivot member.
The point is that the pivot member on the building side and the pivot member on the door side are provided with contact portions that come into contact with each other when the door is opened at a predetermined angle. Further, the present invention includes a pivot member attached to the building side and a pivot member attached to the door side, and the shaft of the door side pivot member is fitted into the hole of the bearing member of the building side pivot member. The gist of the pivot hinge is that the pivot member on the building side and the pivot member on the door side are provided with contact portions that come into contact with each other when the door is opened at a predetermined angle.

[0007] With this configuration, it is easy to set the maximum opening angle of the door with a simple configuration in which the pivot member on the building side and the pivot member on the door side are provided with contact portions that contact each other when the door is opened. Can be performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. 1 to 6,
Reference numeral 1 denotes a pivot hinge including a pivot member 3 attached to the upper frame 2 side of the building in the door installation portion, and a pivot member 5 attached to the upper end of the door 4. The pivot member 3 on the building side includes a substrate 7 attached to the back plate 2a on the upper frame 2 side with screws 6, an operation shaft 9 screwed into a screw hole 8 of the substrate 7 and having an upper end protruding above the substrate 7; One end is engaged with the upper end spherical body 10 of the operation shaft 9 and the other end is the hole 1 of the bearing member 11 of the pivot member 5 on the door 4 side.
2 is connected to a shaft 13 fitted in the connecting rod 2 and is supported by a shaft 14 which is horizontally positioned on the substrate 7 at a position close to the one end.
5 and a guide tube 16 erected on the substrate 7 so as to guide the shaft 13 up and down. The operation shaft 9 is turned from below at the screw hole 8 of the substrate 7 to The shaft 13 is moved up and down via the connecting rod 15 by being moved up and down, so that the pivot member 5 on the door 4 side can enter and exit the hole 12 of the bearing member 11. Further, in the pivot member 3, the guide cylinder 16
A contact portion 17 for setting the maximum opening angle of the door 4 is formed at the lower end of the substrate 7 so as to protrude from the lower surface of the substrate 7.

Next, the pivot member 5 on the door 4 side has a hole 12 in the vertical direction into which the shaft 13 of the pivot member 3 on the building side is fitted, and is provided so as to be horizontally slidable in the main body 18. The bearing member 11 whose position is adjusted by an adjustment screw 19 from one side of the main body 18, and the bearing member 1
1 is provided with a contact portion 20 provided integrally to set the maximum opening angle of the door 4, and the contact portion 20 and the contact portion 17 of the pivot member 3 on the building side form a set of stoppers. are doing. The pivot member 5 on the side of the door 4 includes a mounting plate 22 connected to the main body 18 by screws 21 so that the main body 18 can be placed thereon. The pivot member 5 on the side of the door 4 is provided so as to be built in the upper end of the door 4, and the mounting plate 22 is placed on a horizontal rail 23 inside the door 4 and is connected by screws 24. When the door 4 is attached to the building side, the pivot member 5 on the door 4 side is used to align the hole 12 of the bearing member 11 with the shaft 13 of the pivot member 3 on the building side. The operation shaft 9 is turned by turning the operation shaft 9 in a state where the position of the hole 12 of the bearing member 11 is aligned with the shaft 13 of the pivot member 3 on the building side. It is lowered and fitted into the hole 12 of the bearing member 11.

The contact portion 17 of the pivot member 3 on the building side and the contact portion 20 of the pivot member 5 on the door 4 side.
The pivot member 3 on the building side
The contact portion 17 is inclined such that both end surfaces 17a and 17b are tapered when viewed from below, and the contact portion 20 of the pivot member 5 on the other door 4 side is also viewed from above.
In the embodiment shown in the drawings, one end face 20a of the contact portion 20 of the pivot member 5 on the side of the door 4 and the pivot member on the building side in the embodiment shown in the drawings. One end face 17 of the contact portion 17
a and the contact portion 20 of the pivot member 5 on the door 4 side
And the other end face 17b of the contact portion 17 of the pivot member 3 on the building side is configured to open at an angle of 97 degrees. That is, when the door 4 is installed so as to open inward, the door 4 is 97
In the opened state, one end face 20a of the contact portion 20 of the pivot member 5 of the door 4 comes into contact with one end face 17a of the contact portion 17 of the pivot member 3 on the building side to stop further opening movement of the door 4. When the door 4 is installed so as to open outward, the other end face 20 of the contact portion 20 of the pivot member 5 of the door 4 when the door 4 is opened at 97 degrees.
b is configured to abut the other end face 17b of the contact portion 17 of the pivot member 3 on the building side to stop the door 4 from opening further. That is, either end face 17a, 20a or 17b, 20 of the contact portion 17 and the contact portion 20
b will be used.

Although not shown in the drawings, the lower end of the door 4 is supported in a closing direction by a floor hinge provided with a mechanism for adjusting the maximum opening angle of the door 4. In the embodiment shown in the drawings, the contact portion 17 and the contact portion 20 stop the door 4 from opening further when the door 4 is opened 97 degrees. The angle is not limited to 97 degrees.

When the door 4 is installed so that it can be opened both inside and outside, both end faces 17a, 17 of the contact portion 17 of the pivot member 3 on the building side are provided.
b and both end surfaces 2 of the contact portion 20 of the pivot member 5 on the door 4 side
0a and 20b will be used.

When the door 4 does not support the lower end by a floor hinge or the like, the lower end of the door 4 is also supported on the lower frame side of the building with the pivot members 3 and 5 turned upside down. May be.

Further, in the above embodiment, the door 13 is supported by fitting the shaft 13 of the pivot member 3 on the building side into the hole 12 of the bearing member 11 of the pivot member 5 on the door 4 side. For example, the shaft provided on the pivot member on the door 4 side may be fitted into the hole of the bearing member provided on the pivot member on the building side to support the door 4. That is,
The pivot member 3 on the building side of the above-described embodiment may be attached to the door 4 side, and the pivot member 5 on the door 4 side may be attached to the building side.

[0015]

As described above, according to the present invention, the pivot member on the building side and the pivot member on the door side are provided with contact portions that come into contact with each other when the door is opened. The setting of the opening angle can be easily performed.
