However, sufficient sealing performance can be secured.

Next, the moving frame 11 will be described.
As shown in FIGS. 5 to 8, two sets of rails 32 extending in the front-rear direction are provided on the ceiling 8 of the interior 2. Two moving frames 11 respectively corresponding to the two divided panels 10A and 10B are provided to be movable in the front-rear direction on the two sets of rails 32, respectively. Since the two moving frames 11 have the same structure, the left moving frame 11 will be described below. The moving frame 11 has a beam 40 extending in the left-right direction and two sliders 41 provided on both the left and right sides of the beam 40.

  As shown in FIG. 8, the slider 41 has a U-shaped cross section that opens upward, and the slider 41 is slidably fitted to the beam 40. The beam 40 is engaged with a bolt 42 provided on the inner surface of the slider 41 so that the slider 41 does not fall off the beam 40. Further, as shown in FIG. 5, a bolt 43 for fixing the slider 41 to the beam 40 is also provided. That is, after the two sliders 41 are slid to a predetermined position, the slider 41 is fixed to the beam 40 by the bolt 43, and the length of the moving frame 11 can be adjusted according to the width of the divided panel 10A. It has become. Accordingly, by appropriately adjusting the length of the moving frame 11, it is possible to attach the divided panels 10 </ b> A of various sizes to the moving frame 11.

  As shown in FIGS. 6 and 7, the end portion of the slider 41 on the rail 32 side is received by the horizontal wall portion 44 a of the L-shaped receiving member 44, and the end portion of the slider 41 is further secured by a bolt 45. It is fixed to the horizontal wall 44a. Two vertical roller bearings 46 in contact with the rail 32 are pivotally supported on the vertical wall 44b of the receiving member 44, respectively. Therefore, the moving frame 11 is configured to be movable in the front-rear direction on the rail 32 via the roller bearings 46 positioned at both ends thereof. The receiving member 44 is fixed with bolts and nuts at two front and rear stoppers 47 for preventing the roller bearing 46 from coming off the rail 32.

  As shown in FIGS. 3, 5, and 7, both side portions of the upper end portion of the divided panel 10 </ b> A are partially cut so as not to interfere with the rail 32 and the receiving member 44. Therefore, heat insulating materials 48 made of foamed urethane or the like are provided on the upper sides of both ends of the moving frame 11 so that the sealing performance does not deteriorate at the cut portions. Furthermore, between this heat insulating material 48 and the ceiling 8, the sealing performance is further improved, and the friction between the moving frame 11 and the ceiling 8 when the moving frame 11 moves back and forth can be reduced. A brush 49 is interposed.

  As shown in FIG. 5, in the refrigerator 1 according to this embodiment, a duct 15 is disposed at the right end of the ceiling 8. Therefore, the right and left sliders 41 are fixed to the lower side of the receiving member 44 in the right moving frame 11 so that the right moving frame 11 can move back and forth while avoiding the duct 15. The right moving frame 11 is provided at a slightly lower position than the left moving frame 11.

Next, the mounting bracket 12 will be described. Here, since the two sets of mounting brackets 12 have the same structure, one set of mounting brackets 12 for mounting the left divided panel 10A to the movable frame 11 will be described below.
As shown in FIGS. 5 and 8, the pair of mounting brackets 12 includes a body bracket 50 fixed to the divided panel 10 </ b> A and a U-shaped engagement bracket 51 that can be engaged with the lock body. The main metal fitting 50 is disposed between the two plate members 52 and the two plate members 52, and is engaged with and disengaged from the engagement position (a solid line position in FIG. 8). A claw member 53 provided so as to be rotatable with respect to the plate member 52 over the position (the position of the chain line in FIG. 8), and an operation member 54 for moving the claw member 53 to the disengagement position; Have In FIG. 8, only the plate member 52 on the front side of the paper surface is shown, but actually, another plate member 52 facing the plate member 52 is provided on the back side of the paper surface.

  As shown in FIG. 8, the body fitting 50 is fixed to the end portion (upper end portion in the upright state) of the divided panel 10 </ b> A in a state where the two plate members 52 are parallel to the vertical plane. A recess 52a is formed in the rear side (right side in FIG. 8) of the plate member 52, and the end of the claw member 53 rotates in the direction of arrow a in FIG. 8 in the recess 52a. ing. On the other hand, the U-shaped engagement fitting 51 is fixed to the lower surface of the slider 41 of the moving frame 11 in a state parallel to the upright divided panel 10A, and the horizontal portion 51a is positioned at the same height as the recess 52a. ing. Then, after holding the divided panel 10A in the upright state, the movable frame 11 is moved forward (in the direction of the arrow b) and brought into contact with the upper end of the divided panel 10A. The horizontal portion 51a is inserted into the recess 52a. At this time, the claw member 53 is operated by the inserted horizontal portion 51a, and the claw member 53 rotates from the disengagement position (the position of the chain line in FIG. 8) to the engagement position (the position of the solid line in FIG. 8). The horizontal portion 51a is engaged with the horizontal portion 51a, and the horizontal portion 51a of the engagement fitting 51 is restricted so as not to move in the front-rear direction within the recess 52a. Thus, when the claw member 53 and the engagement fitting 51 in the engagement position are engaged, the divided panel 10 </ b> A is suspended from the movable frame 11. Further, the divided panel 10A is rotatable with respect to the moving frame 11 around the horizontal portion 51a of the engagement fitting 51, and the divided panel 10A is turned to the ceiling 8 as shown in FIG. It is possible to jump up.

  The operation member 54 is provided so as to be rotatable with respect to the plate member 52, and a string 55 is attached to the operation member 54. Then, the operating member 54 moves to a slightly lower position (the position of the chain line in FIG. 8) when the string 55 is pulled downward, and the claw member 53 is engaged in conjunction with the downward movement of the operating member 54. The engagement position is switched to the engagement release position. In other words, by simply moving the operation member 54 downward through the string 55, the engagement state between the claw member 53 and the engagement fitting 51 can be released, and the divided panel 10A can be detached from the moving frame 11. It has become.

  In addition, in the partition wall 3 of the present embodiment, the above-mentioned is also applied to the case where the end portions (lower end portions in the upright state) of the divided panels 10A and 10B are held on the ceiling 8 with the divided panels 10A and 10B flipped up. A mounting bracket 12 is used. That is, as shown in FIG. 9, the main body metal fitting 50 is fixed to the ceiling 8, while the engagement metal fitting 51 is fixed to the lower ends of the divided panels 10A and 10B (see FIG. 3). Therefore, as shown in FIG. 8, after the divided panels 10A and 10B are rotated with respect to the moving frame 11 via the mounting bracket 12, the engaging bracket 51 fixed to the lower ends of the divided panels 10A and 10B is attached to the ceiling. 8, the divided panels 10 </ b> A and 10 </ b> B can be held in a state of being lifted up to the ceiling 8. Further, by pulling the string 55 attached to the operation member 54 from this holding state, the engagement state of the engagement fitting 51 and the body fitting 50 can be released, and the divided panels 10A and 10B can be easily lowered. it can.

Next, the operation of the partition wall 3 when the divided panels 10A and 10B are attached to and detached from the moving frame 11 will be described.
First, when the divided panels 10A and 10B are attached to the movable frame 11, as shown in FIGS. 5 and 8, the movable frame 11 is held while holding the divided panels 10A and 10B in the upright state with the handle 13. Moving forward (in the direction of arrow b in FIG. 8), the moving frame 11 is brought into contact with the upper ends of the divided panels 10A and 10B. At this time, the engagement fitting 51 fixed to the moving frame 11 is engaged with the body fitting 50 provided on the divided panels 10A and 10B, and the engagement fitting 51 is restricted so that it cannot move in the front-rear direction. The split panels 10 </ b> A and 10 </ b> B are attached to the moving frame 11 while being suspended by the tool 51. The left and right divided panels 10A and 10B can move forward and backward together with the left and right moving frames 11, respectively.

  In this state, the divided panels 10 </ b> A and 10 </ b> B are rotatably attached to the moving frame 11 via the attachment fitting 12. Therefore, when the panel 10 is moved in the front-rear direction, the divided panels 10A and 10B are lifted up and slightly separated from the bottom surface 9, so that the resistance between the divided panels 10A and 10B and the bottom surface 9 can be reduced. 10 moves easily.

  On the other hand, when removing the divided panels 10A and 10B from the moving frame 11, the string 55 attached to the operation member 54 is pulled, and the operation member 54 is moved slightly downward. Then, since the engagement state of the main body metal fitting 50 and the engagement metal fitting 51 is released in conjunction with the lowering operation of the operation member 54, the divided panels 10A and 10B are detached from the moving frame 11, and the divided panels 10A and 10B are removed. Can be carried out of the freezer.

According to the partition wall 3 described above, the following effects can be obtained.
After the divided panels 10A and 10B are held upright, the movable frame 11 is brought into contact with the panel 10 to position the panel 10 and the movable frame 11, and then the panel 10 can be mounted on the movable frame 11. . Furthermore, since the panel 10 is mounted on the moving frame 11 by the mounting bracket 12 simply by bringing the moving frame 11 into contact with the panel 10, it is very easy to mount the panel 10. Further, the panel 10 can be detached from the moving frame 11 simply by operating the operation member 54 by pulling the string 55, and the panel 10 can be easily detached.

  Since the divided panels 10A and 10B are rotatably attached to the moving frame 11 by the mounting bracket 12, when the panel 10 is moved in the cabinet 2, the divided panels 10A and 10B are separated slightly from the inner wall. Since the resistance between the panels 10A and 10B and the bottom surface 9 can be reduced, the panel 10 can be easily moved. Further, when it is not necessary to partition the interior 2 with the panel 10, the divided panels 10 </ b> A and 10 </ b> B can be lifted up to the ceiling 8.

Since the panel 10 is divided into the left and right divided panels 10A and 10B, the operation of moving the panel 10 back and forth in the interior 2 or removing the panel 10 from the interior 2 is facilitated.
Furthermore, since the length of the moving frame 11 can be adjusted, it becomes possible to attach panels 10 of various sizes to the moving frame 11.

Next, modified embodiments in which various modifications are made to the embodiment will be described. However, components having the same configuration as in the above embodiment are given the same reference numerals and description thereof is omitted as appropriate.
