A circular fitting rib 41 to be fitted is provided. 42 is a fitting hole which is provided at the center of the movable table 40 and engages with the fitting protrusion 26 of the driving roller portion 23 of the fixed table 20, as shown in FIG. Yes. Reference numeral 44 denotes a set screw having a screw portion 45 that is screwed into a screw hole 27 provided in the fitting protrusion 26 of the driving roller portion 23 through the fitting hole 42 of the movable base 40, and has a diameter larger than that of the fitting hole 42. With a head.

  Next, an example of an assembly procedure of the movable shelf 10 configured as described above will be described. The fixing base 20 is provided with a driving roller portion 23 and first and second auxiliary roller portions 30a and 30b. A flat belt 35 is hung between them, and a belt fixing body 36 is attached to the flat belt 35. It shall be installed.

  First, the peripheral wall 13 of the base 11 is fitted to the outside of the peripheral wall 22 of the fixed base 20 from above, and the protrusions 33 of the auxiliary roller portions 30 a and 30 b are inserted into the fitting holes 16 provided in the top plate 12 of the base 11. The fitting hole 16 is supported so as to be rotatable, and the fitting hole 16 is closed with a lid plate (not shown). A bearing may be provided on the lower surface of the top plate 12, and the protrusions 33 of the auxiliary roller portions 30a and 30b may be supported by this bearing. Next, the fixed shaft 39 of the slide knob 38 is inserted into the slide hole 15 provided in the front peripheral wall 13 of the base 11 from the front side, and screwed to the belt fixed body 36 located on the back side of the slide hole 15 by screwing or the like. Fix it. At this time, the drive roller portion 23 is located at the center of the opening 14 of the base 11.

  Next, the movable base 40 is positioned on the base 11, the fitting hole 42 is aligned with the fitting protrusion 26 of the driving roller portion 23, and the key groove 43 is engaged with the key 28 to move the movable base 40. Lower. As a result, the fitting hole 42 is fitted and coupled to the fitting protrusion 26, the fitting rib 41 of the movable table 40 is fitted into the opening 14, and the movable table 40 is connected to the drive roller unit 23. It can move in the axial direction but is held non-rotatable.

Then, the screw portion 45 of the set screw 44 is inserted from the fitting hole 42 of the movable base 40 and screwed into the screw hole 27 provided in the fitting protrusion 26 of the driving roller portion 23, and the head thereof is moved to the movable base. 40 is brought into contact with the upper surface. A recess may be provided around the fitting hole 42, and the head of the set screw 44 may be placed in the recess to flatten the upper surface.
The movable shelf 10 assembled in this way is accommodated in the refrigerator 1 and its base 11 is fixed to the inner wall of the refrigerator 1 or placed on a support stand provided on the inner wall so that it can be taken in and out.

Next, the effect | action of the movable shelf 10 of the refrigerator which concerns on this Embodiment is demonstrated.
In FIG. 2, when the slide knob 38 is slid along the slide hole 15 in the direction of the arrow, for example, the flat belt 35 integrated with the slide knob 38 via the belt fixing body 36 is moved in the direction of the arrow as shown in FIG. The driving roller 25 of the driving roller unit 23 and the auxiliary roller 32 of the first and second auxiliary roller units 30a and 30b on which the roller is hung are rotated.
When the driving roller 25 of the driving roller unit 23 rotates, the movable table 40 integrated by the key 28 and the key groove 43 also rotates in the direction of the arrow in FIG. If the slide knob 38 is moved in the opposite direction, the movable table 40 rotates in the opposite direction.

In the above description, the case where the movable shelf 10 is configured by the fixed base 20 having the bottom plate 21 and the plate-like movable base 40 is shown, but a number of ventilation holes are provided in the bottom plate 21 and the movable base 40 of the fixed base 20. A cool air may be circulated.
Moreover, although the case where the flat belt 35 was hung between the drive roller part 23 and the auxiliary roller parts 30a and 30b was shown, a timing belt or a chain may be used.

Moreover, although the case where the drive roller part 23 and the movable stand 40 are connected by the key 28 and the key groove 43 has been shown, other means such as spline connection may be used.
Furthermore, although the case where the movable shelf 10 which concerns on this invention was applied to the refrigerator shown in FIG. 1 was shown, it is not limited to this, This invention can be implemented also to the refrigerator of another structure.

  According to the present embodiment, the movable table 40 is rotated by moving the slide knob 38 along the slide hole 15, and the food or the like at the back of the movable table 40 can be drawn to the front, which is very convenient. is there. Moreover, since the slide knob 38 is provided in the front part of the movable shelf 10, the movable stand 40 can be rotated by operating the slide knob 38 without affecting the food stored in the cabinet. . Furthermore, since the movable base 40 is fixed to the drive roller portion 23 provided at the center of the fixed base 20, it can be stably rotated even when a heavy load is applied by foods or the like.

  Further, since the slide knob 38 is provided on the front surface of the movable shelf 10, the slide 40 can be operated quickly without depending on the storage position of the food and the like, so that the movable base 40 can be rotated. Furthermore, since the outer diameter of the movable base 40 is formed to be slightly larger than the inner diameter of the opening 14 of the base 11, it can be easily removed by removing the set screw 44 and pulling it up with the part removed from the opening 14. This is convenient for cleaning and the like. By these, a user-friendly refrigerator can be obtained.
