It consists of 'and. In this configuration, the first corner member 6 and the end face member 8 are exactly the same as the left door 1L. However, as a matter of course, the second corner member 7 ′ and the gasket 10 ′ are different in shape from the left door 1L.
[0011]
The right end surface (the side attached to the frame 2 with a hinge) and the upper and lower end surface structures of the right door 1R are the same as the structures of the respective end surfaces of the left door 1L.
[0012]
Hereinafter, the details of each member will be described with reference to FIG.
The first corner member 6 is an aluminum mold having a substantially L-shaped cross section, and one side of the L shape is in contact with the heat insulating panel 5 and is fixed by a rivet 11. On the other side, an engagement recess 12 that engages with an L-shaped engagement projection 13 provided on the end face member 8 is provided.
[0013]
The end surface member 8 has an engagement convex portion 13 having an L shape on one side, an engagement convex portion 13 having an L shape on the opposite side, and an engagement concave portion 12 incorporated by slide coupling. The end surface member 8 is an aluminum molded product. Then, as shown in FIG. 1 (b), width w, for example 25 mm, the length L is equal to the longitudinal dimension of the door, the end faces 8 that has become elongated member. Therefore, in FIG. 1, the thickness of 50 mm is covered with two end members.
[0014]
In the example of FIG. 1, two end surface members 8 are used. In the second end face member 8, an end member 9 with a gasket is incorporated with a concave-convex engagement structure similar to the engagement between the end face members 8. The main body portion of the end member 9 with gasket is formed of a hard resin, but the gasket portion 9 ′ is formed of a soft resin and is formed integrally with the main body portion. The presence of the gasketed end member 9 prevents heat conduction between the end face member 8 and the second corner member 7.
[0015]
The second corner member 7 is incorporated in the end member 9 with gasket by the same uneven engagement as the engagement of the end surface members 8. The second end member 7 is an aluminum molded product thicker than the first corner member 6 in order to provide a portion for attaching another gasket 10 to one end thereof.
[0016]
The gasket 10 is incorporated into the engaging recess 14 provided at the tip of the protruding portion of the second corner member 7 by uneven engagement. A horizontal projecting portion 15 is integrally formed on the front side (front side of the drawing) of the second corner member 7, and an inward U-shaped recess 16 is provided at the tip, and a long tongue piece of the gasket 10 is provided here. The branch piece 17 provided in 10a bites in and holds the base of the long tongue piece 10a firmly.

[0018]
Next, regarding the opposite end of the right door 1R, the first corner member 6 and the two end surface members 8 have the same configuration and the same assembly as the left door 1L.
[0019]
A difference is that a resin joint 18 is interposed between the second corner member 7 'and the end face member 8, and the second corner member 7' is joined thereto. The joint material 18 is a resin molded product, and is provided with an engaging convex portion 13 on one side and an engaging concave portion 12 on the opposite side. By interposing the joint material 18, heat conduction to the aluminum second corner member 7 ′ can be prevented in the same manner as the end face member 8 that is an aluminum mold. In the case of the left door 1L, the end member 9 with a gasket is made of resin, so that heat conduction is prevented.
[0020]
The second corner member 7 ′ is directly connected to the joint material 18 by uneven engagement. The second corner member 7 'has a recess 19 that is recessed from the left end surface of the door to which the end surface member 8 is joined, corresponding to the second corner member 7 of the left door 1L.
