Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a door, particularly a door provided on a partition panel.

[Prior art]

As shown in FIGS. 3 and 4, generally, the door provided in the partition panel 3 has a door frame 2 arranged in an opening provided in the partition panel 3 and a hinge 4 provided in the door frame 2 serves as a door panel. 1 is pivotally supported, but at this time, as shown in the figure, a type called a pivot hinge in which the rotation center O is located closer to the door tip side than the end surface of the door panel 1 on the hanging side is used. It is often done.

[Problems to be solved by the device]

In this case, if the door stop 5 provided on the inner surface of the door frame 2 is provided not only on the door tip side of the door panel 1 but also on the hanging base side in order to improve the sound insulation of the door, as is apparent from FIG. In addition, the door stop 5 and the door panel 1 interfere with each other. Since a gap has to be provided between the door panel 1 and the door frame 2, it has a problem of poor sound insulation. The present invention has been made in view of such a point, and an object thereof is to provide a door that can obtain good sound insulation even in the case of a pivot hinge.

[Means for Solving the Problems]

Therefore, the present invention is directed to an abutting portion between a door-panel-side surface of a door-stop member that is provided on the inner surface of a door frame and is capable of contacting one surface of the door-panel-hanging side and a door-stop on the door-panel-hanging side. And is an inclined surface having an inclination in a horizontal section, and the door stop has inclined surfaces on both sides in the horizontal section. [Operation] According to the present invention, since the door panel and the door stop abut on each other where the horizontal cross section is an inclined surface, it is possible to eliminate the interference between the door panel and the door stop and at the same time to obtain the sound insulation effect. [Embodiment] The present invention will be described in detail below with reference to the illustrated embodiment.
As shown in the figure, the illustrated door is arranged in the opening of the partition panel 3, and is arranged in the door frame 2 and the door frame 2 fixed to the inner surface of the opening. The door panel 1 is pivotally supported by a hinge 4 provided on the door frame 2 and the door panel 1. In the figure, O indicates the center of rotation of the door panel 1. The door panel 1 is composed of a panel body 10 and an edge member 11 fixed to a side end of the panel body 10. The edge member 11 formed as an extruded product of metal or synthetic resin has a corner in a horizontal section. The inclined surfaces 12 and 12 are inclined. On the other hand, the door frame 2 is also formed as an extruded product of metal or synthetic resin, and a door stop 5 is attached to a rib 20 protruding on the inner surface thereof over the entire length in the longitudinal direction. The door stopper 5 is formed as a packing made of hard rubber or synthetic resin, and its horizontal section has a pentagonal shape. The door panel 1 side has inclined surfaces 5 on both sides.
One of the inclined surfaces 50 of 0 and 50 is directed. The inclination angle of the inclined surface 50 is substantially the same as the inclination angle of the inclined surface 12 of the edge member 11 of the door panel 1. Moreover, even if the door stop 5 of the door frame 2 is attached upside down, the other inclined surface 50 of the door stop 5 faces the door panel 1 side. Therefore, in the illustrated door, when the door panel 1 is closed, not only on the door tip side of the door panel 1, but also on the hanging side, the door panel 1 comes into contact with the door stop 5, and this contact is Inclined surface 50 with 5 per door,
It is made by the inclined surface 12 of the edge member 11 of the door panel 1. Since the inclined surfaces 50 and 12 that are inclined in the horizontal section are brought into contact with each other, as shown in the figure, the rotation center O of the door panel 1 is the end surface of the door panel 1 on the hanging side. The door panel 1 can be opened and closed without interfering with the door stop 5 even when the door panel 1 is located on the door end side. As the door stopper 5, one having a permanent magnet held therein or one made of hard rubber or synthetic resin containing permanent magnet powder may be used, and a magnetic material may be used as the edge material 11 of the door panel 1. In this case, the magnetic attraction force is 5 per door and the door panel 1
The air-tightness and the sound insulation can be further enhanced due to the effect of the air-tightness.

[Effect of device]

As described above, in the present invention, the suspension side of the door panel can be brought into contact with the door stop without causing any trouble in opening and closing the door panel, and therefore high airtightness and sound insulation can be obtained. It is what is done. Further, when the door stop is attached to the door frame, even if the door stop is installed upside down, the door stop is such that one of the inclined surfaces on both sides is brought into contact with the inclined surface on the door panel side, Since the door stop has no vertical direction, it is easy to attach the door stop to the door frame.
