Description

Functional door opening/closing conversion device {Automatic device of opening/closing of the door}

The present invention relates to a functional door opening/closing changing device, and more particularly, to a functional door opening/closing converting device for realizing an opening/closing type door that can be opened and closed quickly by minimizing the protruding door by minimizing the turning radius of the door.

In the case of doors that need to reliably block the movement of smoke or flames from one side of the door to the other, such as the front door of a house or the outside door of an office, when the door is closed, the outer edge of the door is exactly on the inner edge of the door frame. must be installed to match. A middle door is often installed in the entrance hall of an apartment, but in the case of a middle door inside an apartment, if it consists of two opening and closing doors, even if one door is opened as much as possible, the space in the open part is narrowly composed. have. Therefore, the door is composed of three, and when the door leaf is configured to be opened by folding between the door leaf and the door leaf instead of the conventional configuration, there is an advantage in that the open part is widened when the middle door is opened.

However, in the case of a door leaf that opens while being folded, when the door leaf opens and closes, the hinge of the door is configured to only rotate, so that there is a problem in that each leaf is not properly folded or unfolded.

In addition, the damping device for a door that can be opened and closed while rotating in both directions refers to a device that is installed on the floor of an entrance door of a building, an upper door frame, or inside a door to buffer the door so that the door closes automatically and slowly when the door is opened and closed. A conventional damping device for a door has a mechanism in which a buffer force is controlled while hydraulic oil inside the damping device moves by a link operation of a cam, a piston, and a spring that rotate when the door is opened and closed.

In the case of a door damping device using a cam as described above, there is a high possibility that the cam under the action of a strong force is worn and the operation accuracy is deteriorated, but also has a problem in that the durability of the door damping device is deteriorated. On the other hand, when a door that can actually be opened and closed is installed, there is a lot of demand or demand for a function that can keep the degree of opening and closing of the door fixed and especially the degree of opening and closing in stages. In some cases, these requirements are not met.

As described above, the opening and closing is formed using various methods when opening and closing in both directions, but there is a problem in that the structure is complicated and the cost is increased in the method for automatic implementation.

The problem to be solved by the present invention is
