On the other hand, the upper and lower openings 22 of the storage room 20 partitioned by the middle partition 23 are closed by two sets of double doors (insulated doors) 2 and 28 so as to be openable and closable. In addition, guide members 27 and 27 are respectively attached to the top surface of the storage room 20 and the lower surface of the partition 23 located at the center of the upper and lower openings 22.

As shown in FIG. 2, the doors 2 and 28 are composed of an outer surface member 3 and an inner surface member 5 to form a main body 7. Is attached. As shown in FIG. 3, the outer surface material 3 includes a front surface 3A, a side surface 3B formed by bending the edge of the front surface 3A backward at a right angle at a predetermined curvature, and a rear end of the side surface 3B inside. And a rear flange 3C formed by bending at an inner right angle.

A door sash 4 is attached to the outer surface material 3. The door sash 4 is formed by extrusion molding of a hard rigid resin.

A projection 4B is formed at the center of the surface of the main body 4A of the door sash 4, and the main body 4A corresponding to the projection 4B is formed.
An arm 4C that extends downward is formed on the back surface of A, and an outwardly opened engaging groove 4D is formed between the arm 4C and the main body 4A. The front end of the rear flange 3C of the outer surface material 3 is inserted and engaged in the engagement groove 4D, and the door sash 4 is attached to the outer surface material 3. Then, an inner surface material 5 made of a hard resin or a steel plate is brought into contact with the inner surface of the projection 4B of the main body 4A of the door sash 4 and loaded in a foaming jig (not shown) in this state, and the outer surface material 3, the door sash 4
The door body 7 is completed by filling the foam insulation 6 between the inner surface members 5.

The rotary partition member 13 provided on the non-pivot side inner surfaces of the doors 2 and 28 includes a mounting plate 8, a holder 29 and a partition body 12. To assemble this, the gasket mounting sash 31 is fixed to the rear flange 3C with the screw 9 while being sandwiched between the L-shaped mounting plate 8 and the door sash 4 on the non-pivot side of the door 2.

The mounting plate 8 has a holder 29 on the inner surface material 5 side.
Are fixed by screws 11, and hinge members 3 attached to upper and lower ends of the holder 29 are attached to the holder 29.
5, the partition 12 is attached. The gasket mounting sash 31 has a mounting portion 31B in which a mounting groove 31A for inserting the arrowhead-shaped portion of the gasket 30 is formed. The end of the mounting plate 8 extends to the outer surface of the mounting portion 31B of the gasket mounting sash 31, and the end is bent along the outer shape of the gasket mounting sash 31, and there is a regulating portion 8A. Are formed.

The restricting portion 8A functions to press the mounting portion 31B of the gasket mounting sash 31 against the door body 7 from above.

The partition member 12 extends in the longitudinal direction of the door body 7 and is attached to a resin body 14 having a U-shaped cross section as shown in FIG. A front plate 15 made of a steel plate, a heat insulator 16 inserted into the main body 14 and a heater 17 attached to the back of the front plate 15.
The cap 32 having a guide groove 32A for engaging and guiding the guide member 27 (FIG. 1) is fitted to the upper end and the lower end of the partition body 12, respectively.

The cap 32 is rotatably supported by a hinge member 35 about an axis extending in the longitudinal direction.
It is attached to the holder 29. Here, when the door 2 is closed, the magnet gasket 30 (FIG. 3) for sealing between the doors 2 and 28 and the heat insulating box 18 has its arrowhead-shaped portion inserted into the mounting groove 31A of the gasket mounting sash 31. It is attached by engaging.

With the above construction, as shown in FIG. 3, when the door 2 is opened, the partition member 12 is guided by the engagement between the guide member 27 (FIG. 1) and the guide groove 32A, and the front plate 15 is moved to the other door. 2
It is rotated clockwise in FIG. 3 so as to face eight directions (indicated by broken lines in FIG. 3). As a result, the partition body 12 can move forward avoiding the other door 28, and the two doors 2, 28 can be opened and closed independently. Also, when you close the door 2,
The guide groove 32A penetrates into the guide member 27 (FIG. 1) and is guided in the opposite direction to the previous one, and is rotated counterclockwise in FIG.
The front plate 15 is directed forward at the opening 22. Thereby, the contact surfaces of the gaskets 30 of the doors 2 and 28 are formed.

Is held parallel to the front plate 15. That is, the gasket mounting sash 31 is
And a restricting portion 8 of the mounting plate 8.
Since A is pressing the gasket mounting sash 31 against the door body 7, the mounting portion 3 having the mounting groove 31A is formed.
It is possible to prevent the deformation of the gasket 30 due to the deformation of the gasket 1B or the falling off of the gasket 30. This prevents interference between the partition body 12 and the gasket 30 and allows the partition body 12 to rotate to a proper position. Since the gasket 30 can also be brought into close contact with the partition body 12, it is possible to prevent a decrease in the sealing performance of the doors 2 and 28 due to a change in the direction of the gasket 30. The gasket mounting sash 31 is attached to the mounting plate 8.
In addition, the sash for attaching the gasket can be firmly attached to the door body because the sash is fixed to the door 2 with the screw 9.

In this embodiment, as shown by a broken line in FIG. 3, when the door 2 is opened, the guide member 27 (FIG. 1) and the guide groove 32A are opened.
The partitioning body 12 is guided by the engagement with, and is rotated clockwise in FIG. 3 so that the front plate 15 faces the direction of the other door 28. In this case, when the partition 12 collides strongly with the holder 29, the partition 12 may rotate in the direction shown by the solid line due to the reaction, and the door 2 may not be closed.

In order to reduce the impact at the time of the collision, in this embodiment, a shock absorbing band 50 made of a damping rubber or a damping resin having a smaller coefficient of restitution than a metal or a resin is attached to the holder 29. Can be This impact relaxation band 50 is
For example, it is adhered by a double-sided tape or the like, and is provided so as to extend substantially in the longitudinal direction of the door body 7. However, the present invention is not limited to this. For example, with reference to FIG. It can be mounted only in the vicinity.

The shock absorbing strip 50 is, for example, alpha gel, which is a vibration-absorbing material of silicon gel, which is a viscoelastic body, and is excellent in shock absorption.

As described above, in the present embodiment,
Since the band-shaped shock absorbing band member 50 having a relatively large area is adhered so as to extend substantially completely in the longitudinal direction of the holder 29, the shock when the partition body 12 collides with the holder 29 is sufficiently mitigated. Is done. Therefore, the trouble that the partition body 12 rotates in the opposite direction due to the recoil when the partition body 12 collides with the holder 29 as in the related art and the door does not close cannot be solved.

Although the present invention has been described based on one embodiment, it is apparent that the present invention is not limited to this. For example, the impact buffer strip 50 may be bonded to the partition 12 side, or may be fixed by a method other than bonding.

[0029]

According to these inventions, since the strip-shaped impact absorbing strip having a relatively large area is provided, the impact when the partition body collides with the holder can be sufficiently reduced. Therefore, the problem that the partition body turns in the opposite direction due to the recoil when the partition body collides with the holder and the door does not close as in the related art is solved.
