-Insulation structure of frame-
In the open door as shown in the present embodiment, for example, it is considered that the expected width dimension of the resin frame is increased to enhance the heat insulation of the entire door body 2. For example, the metal left vertical frame 231 and the resin left frame are considered. As can be seen in the vertical frame 232, the expected width dimension of the resin left vertical frame 232 is increased to approximately half of the expected width dimension of the entire frame, and at the approximate center of the glass frontage in the expected direction, at least at the middle position in the expected direction. It has been considered that a metal frame and a resin frame are joined to enhance heat insulation performance.
However, the joining of the metal left vertical frame 231 and the resin left vertical frame 232 is such that engaging pieces 231b and 231c provided on the indoor side surface of the metal left vertical frame 231 are formed on the outdoor side surface of the resin left vertical frame 232.

The hollow portion is arranged on the indoor side and at least on either the inner peripheral side or the outer peripheral side of the engagement piece for frame joining, so that the heat insulation performance of the frame is improved.
Hereinafter, the heat insulating structure of the composite frame of the door of the present embodiment will be described in detail with reference to FIG.

  The hollow main body 131a of the metal left vertical frame 131 of the left vertical frame 13 has a step 131d in which the inner peripheral surface changes in the outer peripheral direction at a substantially central position in the expected direction of the left vertical frame 13. The main resin left vertical frame 132 is attached to the resin frame mounting portion 131b of the metal left vertical frame 131, so that the stepped portion 131d and the inner peripheral surface of the main resin left vertical frame 132 allow the inside of the left vertical frame 13 to be inside the room. A concave portion a that is concave in the outer peripheral direction is formed on the peripheral surface.

An airtight material holding portion is formed on the indoor side surface of the step portion 131d of the main body portion 131a. The airtight material holding portion holds an airtight material s2 that extends the fin pieces in the inner circumferential direction, and the tip thereof will be described later. The space A is formed on the indoor side of the resin left vertical frame 232 of the door body 2 by contacting the outer peripheral surface of the resin left vertical frame 232 existing on the indoor side of the left vertical frame 23.
The space A is formed between the space where the hinge 71 is arranged and the indoor space by the airtight material s1 held by the main resin left vertical frame 132 abutting on the indoor side surface of the resin left vertical frame 232 of the door body 2. It becomes an independent closed space arranged in the space, and the heat insulation performance can be improved.

  Further, the space A is a heat insulating space which is wider in the direction of finding than the space between the frame 1 in which the hinge 71 is disposed and the door main body 2 by the concave portion a formed by the stepped portion 131d, so that it is airtight. The momentum of the air entering through the gap between the materials is weakened by the space A, and further penetration into the room can be prevented, so that the direct transfer of heat by the air can be prevented.

In the resin left vertical frame 232 in which the airtight material s1 held by the main resin left vertical frame 132 and the airtight material s2 held by the airtight material holding portion of the step 131d abut, a plurality of hollow portions are found on the indoor side. A hollow main body portion 232a is formed side by side in the direction, a small hollow portion 232b is formed on the outer periphery, and an inner peripheral small hollow portion 232c is arranged on the inner peripheral outdoor surface.
The outdoor wall of the inner peripheral small hollow portion 232c extends in the outer peripheral direction to form an engaging portion 232d that opens toward the outer periphery, and has an inverted L-shape from the outer outdoor surface of the hollow main body portion 232a. An engaging portion 232e that protrudes and opens in the inner circumferential direction is formed.
A partition wall 232f is formed between the inner peripheral side engaging portion 232d and the outer peripheral side engaging portion 232e.

The metal left vertical frame 231 of the left vertical frame 23 has an outer peripheral portion that is enlarged in the expected direction to form a hinge attachment portion, and the indoor side surface on the inner peripheral side of the hinge attachment portion has an inner peripheral side and an outer peripheral side. Engagement pieces 231b and 231c for joining the resin left vertical frame 232 are formed to protrude from the sides. The inner peripheral side engaging piece 231b is formed so as to be displaced from the glass frontage in the outer peripheral direction by the finding width dimension of the inner peripheral side small hollow portion 232c, and the inner peripheral surface of the inner peripheral side engaging piece 231b is formed. It is possible to dispose a hollow portion made of resin in the space.
Then, by engaging the engaging pieces 231b and 231c of the metal left vertical frame 231 with the engaging portions 232d and 232e of the resin left vertical frame 232, the resin left vertical frame 232 is joined to the indoor side of the metal left vertical frame 231. The space between the small inner hollow portion 232c and the engaging portion 232e between the metal left vertical frame 231 and the resin left vertical frame 232 is formed by a plurality of hollow portions divided by a partition 232f. A layer is formed.

As described above, when the resin vertical frame is joined to the indoor side of the metal vertical frame, the hollow main body portion 232a is arranged on the indoor side of the engaging piece 231b for engaging the resin vertical frame, and Since the inner peripheral side small hollow portion 232c is disposed on the side (glass front side), the hollow portion surrounds the indoor side and the inner peripheral side of the engagement piece 231b, and the heat to the indoor side and the glass front side is dissipated. Transmission can be suppressed by the hollow heat insulating structure, and the heat insulating performance can be improved.
Further, since the small hollow portion 232b is arranged on the outer peripheral side of the hollow main body portion 232a, the heat transmitted in the room direction from the space between the vertical frame of the frame and the vertical frame of the shoji is small. It can be suppressed by the hollow heat insulating structure in the hollow part.
Furthermore, the interior side surface of the metal frame is entirely covered with the hollow portion of the resin frame over the entire circumference, and a hollow portion is formed by the metal frame and the resin frame to form an air space between the metal frame and the resin frame. By interposing, the contact area between the metal frame and the resin frame can be reduced as much as possible, thereby suppressing heat transfer.

In the present embodiment, the heat insulating structure of the frame is described using the engagement piece 231b on the inner peripheral side of the metal left vertical frame of the left vertical frame. However, heat insulation by surrounding the engagement piece with a hollow portion is described. Can also be adopted for the engagement piece on the outer peripheral side.
In addition, the heat insulation structure of the frame of the present embodiment can improve the heat insulation performance of the fitting by adopting the vertical frame having a large dimension, but also adopts the heat insulation structure of another frame or frame. It is also possible.
