Description

Hinge device for door-to-door use and door return {A Hinge Device for Door}

The present invention relates to a hinge device that can be used in a toilet door and when the door is not in use while returning the door to its original position. The male and female hinge members, which are inclined to each other and inclinedly contact with each other to provide a return force, are detachably mounted to the supports of the hinge means, so that the hinge device can be easily assembled in the field on both sides, and the door is not used. And a hinge device that enables a more practical left-right combined use of the door to return to the original position to maintain the appearance beauty of the toilet.

Doors installed in rest areas on highways and restrooms in large buildings, especially public restrooms with multiple spaces, are installed to return to their original positions when the restroom is not in use.

For example, if the door is completely open when the toilet is not in use, the interior of the toilet is exposed to the outside, so the interior environment of the toilet is not beautiful, so the door is a toilet without the toilet. It will return to make it possible to cover the inside of the to some extent.

On the other hand, the degree of opening of the toilet of the door is also important in the toilet in which the door is returned. For example, if the door is opened too much even after the door is returned, the interior of the toilet is exposed to a high degree, which is not preferable. If the toilet is covered, it is difficult to recognize the use of the toilet from the outside while affecting the breathability, it is preferable to maintain the appropriate degree of toilet opening after the return of the door.

In addition, since a toilet such as a rest area or a building (building) has a large number of doors installed, if the doors are opened in an unused state, this is also not good in appearance.

Thus, when the doors of the toilet are not in use, the doors are returned to their original positions so that the interior of the toilet can be almost covered (hereafter, the original position means the position when no force is applied to the door) and is maintained. It is necessary to make sure.

On the other hand, a hinge (door structure) for returning a door of a public restroom installed in such a rest area or building (large building) to a specific position is known.

For example, in the registered application 20-0255850, one of the applicants of the present application filed in Korea, a hinge for returning the door is disclosed, which is illustrated in FIG.

That is, as shown in Figure 1, the lower portion of the door 100 is welded integrally with the bracket 112, the hinge shaft 114 is integrally closed the water closing adjustment shaft 110 is disposed, the door 100 The lower portion of the wall (support) 120 which is disposed adjacent to one side of the () is inserted into the support pipe 134 vertically connected as a bracket 132 is fixed as a stop screw 136, the hinge shaft 114 is fitted The hinge arm 138 is formed, the arm closing adjustment shaft 130 is disposed.

Since it is integrally welded, it is virtually impossible to adjust the angle of the inclined cam surface 110a of the male closing adjustment shaft 110, and thus, it is difficult to adjust the contact angle of the inclined cam surface, thereby making it difficult to adjust the return (angle) through the door. Therefore, it is impossible to fix the bracket of the water closing control shaft side to the wall side when the hinge is installed, which limits the construction conditions when the hinge is installed.

In addition, since the water closing adjustment shaft 110 is integrated with the hinge shaft 114 and welded integrally to the bracket 112, when the hinge 150 is installed between the door and the wall of the actual toilet, the water closing is possible. Assembly of the control shaft 110 and the arm closing control shaft 130 was also cumbersome.
