Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments described herein but may be embodied in other forms. Rather, the embodiments introduced herein are provided to ensure that the disclosed subject matter is thorough and complete, and that the spirit of the invention will be fully conveyed to those skilled in the art.

3 is a longitudinal sectional view showing a door system according to an embodiment of the present invention.

Referring to FIG. 3, the door system according to the present invention may include a door frame 100, a door 110, a door closer 120, a link assembly 130, and a heat insulating member 200.

The door frame 100 is fixedly mounted to an entrance (not shown) formed on a wall in the building, and the door 110 is coupled to the door frame 100 to open and close the entrance. Here, the door 110 may be coupled to the door frame 100 by a predetermined hinge (not shown) to open and close the door.

The door closer 120 is for controlling the closing speed of the door 110, and is fixedly installed at a predetermined position of the door 110 by the fastening member 112. Description of the detailed configuration and operation state of the door closer 120 will be omitted, since it will be apparent to those skilled in the art.

The link assembly 130 has one side connected to the door frame 100 and the other side connected to the door closer 120. Accordingly, the link assembly 130 may transmit a predetermined force generated when the door 110 is opened or closed to the door closer 120, and the door closer 120 may be removed from the link assembly 130. The transmitted force is transmitted to the hydraulic cylinder (not shown) provided therein to control the closing speed of the door 110.

The heat insulating member 200 is interposed between the door 110 and the door closer 120. That is, the heat insulating member 200 is fastened to the fastening member 112 together with the door closer 120 and the door 110 in a state interposed therebetween when the door closer 120 is fixed to the door 110. By fixed installation. That is, the door closer 120 according to the present invention is not fixedly installed in a state of directly contacting the door 110, but is fixedly installed to the door 110 through the heat insulating member 200.

On the other hand, the heat insulating member 200 is coupled to the bottom surface of the door closer 120 in contact with the door 110 may be made integral with the door closer 120. That is, the door closer 200 may include a heat insulating member 200 coupled to the door 110 contact surface, that is, the bottom surface. In this case, the door closer 120 and the heat insulating member 200 may be coupled by an adhesive or the like, or may be coupled by a fastening member. That is, the present invention is not limited thereto.

As such, when the heat insulating member 200 is combined with the bottom surface of the door closer 120 to be integrated, the heat insulating member 200 may be the same as the work of fixing only the door closer 120 to the door 110. It can be interposed between the door closer 120 and the door 110, it is convenient. That is, the fixed installation of the door closer 120 integrated with the heat insulating member 200 at the bottom is fixed to the door 110, the door closer 120 and the heat insulating member 200 is made of a separate door closer 120 When fixed to the door 110 can be made easier than the operation of fixing the door closer 120 to the door 110 in a state in which the heat insulating member 200 is interposed therebetween, it is convenient.

As described above, according to the door closer and the door system according to the present invention, the heat transmitted through the door 110 in the case of fire can be blocked from being transferred to the door closer 120 by the heat insulating member 200, Accordingly, damage to the door closer 120 generated by the heat generated in the fire is transferred to the door closer 120 through the door 110.

In addition, according to the door closer and the door system according to the present invention, the door closer 120 is fixed to the door 110 so that the heat insulating member 200 is interposed between the door 110 and the door closer 120. In addition, it is possible to prevent damage to the door closer 120 due to heat generated in a fire at a simple yet low cost. This can save much more cost than manufacturing the door closer 120 itself so as not to be damaged at a predetermined temperature or more, and furthermore, according to the present invention, even if the door closer 120 is not manufactured to be damaged at a predetermined temperature or more. It can be installed on fire doors.

Meanwhile, in a fire, heat through the door 110 may be transferred to the door closer 120 through the fastening member 112. However, heat transmitted through the fastening member 112 is insufficient to cause damage to the door closer 120. The damage of the door closer 120 due to heat in the event of fire occurs as the oil provided in the door closer 120 is boiled and exploded, and the heat transferred through the fastening member 112 causes the oil to boil and explode. Because it is not enough to cause. Indeed, the currently used door closer 120 is manufactured to be smoothly operated at about 1000 ° C. or less, and the door closer 120 is heated to 1000 ° C. or higher due to heat transmitted through the fastening member 112. Because it is impossible.

Preferably, the heat insulating member 200 may be made of an aerogel. These aerogels have recently been used for thermal insulation of pipelines, replacing asbestos or glass fibers.

The aerogel is a heat insulating material having excellent heat insulating properties, even if provided as thin enough to be interposed between the door 110 and the door closer 120 as in the door system according to the present invention can expect a sufficient heat insulating effect.

In addition, the airgel is very excellent in workability, the water repellency is also a very excellent heat insulating material, can be easily processed to a size that is interposed between the door 110 and the door closer 120, the water in the door closer 120 Soaking can also be prevented.

In addition, the airgel may be provided from a manufacturer in the form of a sheet. Therefore, it can be cut and used as needed. In addition, the airgel may be in close contact with the door 110 and the door closer 120 by the fastening member 112 because the airgel is made of a soft material like general fibers. Of course, the adhesive may be further interposed.

According to the experiment of the inventor of the present application, it was found through the experiment that the airgel can obtain a very effective fire protection performance. In other words, an experiment was performed to apply heat through an oxygen cutter so that a panel formed of an iron plate melted to form a hole. Through this experiment, a heat hole was formed in the panel, but the airgel was not damaged. Therefore, it was found that the effect as a heat insulating material for preventing the heat generated in the fire is transmitted to the door closer 120 is very excellent.

On the other hand, when the heat insulating member 200 is used by cutting the heat insulating material in the form of a sheet, such as aerogel to the required size, only one layer is interposed between the door 110 and the door closer 120 or the door closer 120 Although it may be coupled to the bottom of, in some cases, the heat insulating material coupled in two or more layers may be interposed between the door 110 and the door closer 120 or coupled to the bottom of the door closer 120.

Preferably, the door system according to the present invention is provided in the door 110, the heat insulating member 210 interposed between the handle portion 150 and the door 110 to allow the user to open and close the door 110. It may further include.

The handle portion 150 is a portion that is held when the user opens or closes the door 110, and the user holds the handle portion 150 to open or close the door 110 even in a fire. In this case, the door 110 If heat transmitted through) is transferred to the handle part 150 and the handle part 150 is heated, the user may be burned. Therefore, the heat through the door 110 by the heat insulating member 210 can be prevented from being transmitted to the handle portion 150, it is possible to prevent the user's burn.

On the other hand, the heat insulating member 210 may be made of the same material or the same shape as the heat insulating member 200 interposed between the door 110 and the door closer 120.
