The heat insulating bar 130 is for blocking heat exchange between the inner frame 110 and the outer frame 120 and may be made of a material having a very low thermal conductivity.

At this time, the heat insulating bar 130 must be connected to the inner frame 110 and the outer frame 120 to maintain the structural coupling between the inner frame 110 and the outer frame 120 and the door D.

Accordingly, it is preferable that the heat insulating bar 130 is formed of a material having a low thermal conductivity and a sufficient strength and a low stress (stretchability).

Therefore, even when a temperature difference occurs between the indoor and the outdoor, the heat insulating effect between the inner frame 110 and the outer frame 120 is blocked by the heat insulating bar 130, and the heat insulating effect can be greatly improved.

2 is a view for explaining a process of manufacturing the main frame of FIG.

First, a primary processed main frame 100a in which an inner frame 110 and an outer frame 120 are connected to each other by a connecting portion 110a as shown in the upper part of FIG. 2 can be manufactured. For example, when the main frame 100 is made of aluminum, the primary machining main frame 100a as shown in the upper part of FIG. 2 can be manufactured by extruding aluminum.

At this time, one side of the connection part 110a may be formed with a heat insulating part 111a to be formed with the heat insulating bar 130. The inside frame 110 and the outside frame 120 are formed inside the heat insulating part 111a. The separation preventing portions 111 and 121 may be formed so as to be connected to the separation preventing portions 111 and 121, respectively.

The inner subframe 210 and the outer subframe 220 are physically separated from each other to block the heat exchange between the indoor side and the outdoor side in the case of the subframe 200, And the outer frame 120, respectively.

The inner sub-frame 210 and the outer sub-frame 220 may be connected by a sub-insulating bar 230.

On the other hand, when the door D is closed, the subframe 200 is close to the door frame, so that a configuration for preventing the fingers or the like of the passengers from being caught between the door D and the door frame may be required.

Accordingly, the subframe 200 of the present invention can further comprise the cushion bar 240 and the elastic bar 250 as shown in Fig.

The cushion bar 240 may be coupled to at least one of the inner sub-frame 210 and the outer sub-frame 220 so as to be exposed and inserted into the door frame side. And it is preferable that they are respectively provided in the frame 220 to form a double-trough.

In other words, by configuring the cushion bar 240 in a double-wall configuration, it is possible to shut off air movement between the room and the outside even if additional devices such as a lock are formed at the center of the heat insulating frame A for the door.

The elastic bar 250 is formed inside the inner sub-frame 210 and the outer sub-frame 220 so as to press the cushion bar 240 toward the door frame, and various configurations can be applied. However, In order to improve the field assemblability of the heat insulating frame A for the door, it can be formed in the shape of a leaf spring and will be described in more detail below.

And curved portions 212 and 222 are formed in the outer sub-frame 120, respectively. In addition, by forming the shape of the door frame side of the heat insulating frame A in a curved surface, it is possible to improve visual aesthetics.

In other words, when the primary processed sub-frame 200a made of aluminum is extruded as shown in the upper part of Fig. 5, a curved surface portion of a shape protruding outside (the upper side in Fig. 5 toward the door frame side) (212, 222) are formed.

In filling the heat insulating portion 211a including the release preventing portions 211 and 221 with a heat insulating material such as azon, the outer surface of the curved surface portions 212 and 222 protruding as shown in the center of FIG. So as to be cured.
