Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting part of a door closer in which a door member is connected to a building above the door by a link member, and a force of the door crower is transmitted to the door side. It is about structure.

[0002]

2. Description of the Related Art Conventionally, in order to transmit the force of a door cloaker to a door side, as shown in FIG.
It is known that the door closer 2 attached to the upper end and the building 3 above the door 1 are connected by link members 4 and 5 so that the force of the door crazer 2 is transmitted to the door 1 side. In FIG. 5, the door crower 2 is attached to a surface facing the opening direction of the door 1, and the other end and one end of a link member 4, one end of which is connected to a rotation drive shaft of the door ark 2, are pivotally supported on the building 3 side. The other end of the link member 5 is pivotally connected. More specifically, when the door clouser 2 is attached to a surface facing the opening direction of the door 1, as shown in the drawing, a link member 5 whose one end is pivotally supported on the building 3 side is connected to the building 3 with the door 1 closed. The link member 4 projects substantially at a right angle, and the link member 4 is pivotally connected to the link member 5.

[0003]

However, in the above-described conventional configuration, when the door clouser 2 is mounted on the surface of the door 1 facing the opening direction, the link members 4 and 5 are in a state where the door 1 is closed. At building 3
When performing repair work on the door surface or the inner wall surface of the building after the door protrudes from the side and attaches the door crazer, there is a problem that the link members 4 and 5 that protrude greatly obstruct the work and it is difficult to perform the work. When the door clouser 2 is attached to the surface of the door 1 facing in the opening direction, the link member 4 and the link member 5 protrude greatly from the building 3 when the door 1 is closed. When the curtain 6 is provided in parallel as shown by a two-dot chain line in FIG. 5, for example, the door 1 is so arranged that the curtain 6 does not contact the link member 4 and the link member 5 when the door 1 is closed.
However, there is a problem that the curtain 6 must be provided in a state where the curtain 6 is separated therefrom.

SUMMARY OF THE INVENTION The present invention solves such a problem. When a door closer is mounted on a surface facing the opening direction of a door, the protrusion of a link member connecting the door crazer and a building above the door is reduced. It is an object of the present invention to facilitate repair work on a door surface or a building inner wall surface, and to enable a curtain to be provided close to a door.

[0005]

In order to solve this problem, the present invention provides a door-closer which is attached to the upper end of a surface facing the opening direction of a door, and has one horizontal end connected to a rotation drive shaft of the door-closer. At the other end of the link member, one end of the other horizontal link member pivotally supported on the building side is connected to the other end of the door locker. A is a connection position between the rotary drive shaft and one end of one link member, B is a connection position between one end of the other link member and the building,
When the connecting position between the other end of one link member and the other end of the other link member is C, the distance from the rotation axis of the door is configured to be longer in the order of A, B, and C. The link member is configured to be close to a surface facing the opening direction of the door and a wall surface of the building when the door is closed.

[0006] With this configuration, when the door locker is mounted on the surface facing the opening direction of the door, the protrusion of the link member connecting the door locker and the building above the door is smaller than that of the conventional example. Repair work on door surfaces and building inner walls becomes easier. Further, since the projection of the link member is small as described above, the curtain can be provided close to the door.
