Abstract

PURPOSE:To obtain a stretchable shelf device for a deep freezing refrigerator which is rotatably displaceable by a simple operation even if an upper space is narrow. CONSTITUTION:A front shelf 7 is supported to a front side guide groove 2 of supporting means 1, a rear shelf 8 is supported to a rear side support 3 of the means 1, and rotation of the shelf 8 is prevented by engaging with a container 9 of the shelf 8 of the shelf 7 engaged with the groove 2. The shelf 8 is rotated from a horizontal position of the support 3 to be retracted by eliminating engagement of a retracting mechanism 21 with the groove 2 of the shelf 7 when the shelf 7 is moved to the container 9. Thus, state altering of the shelf device is facilitated. An upper space for rotating the device is narrowed thereby to reduce an installation restriction of other shelf to be disposed above.

In the figure, (1) is a support means composed of supports provided on both sides in the width direction of the refrigerator and refrigerator, respectively, a front guide groove (2) horizontally arranged in the front of the refrigerator, Rear support (3), rear support near the rear
(3) A rotation support portion (4) provided on the rear side of the rear support portion (3) and a descending guide portion (5) extending downward from the rotation support portion (4). ) And a blocking portion (6) provided at the lower end of the descending guide portion (5).

Reference numeral (7) is a front shelf which has a size corresponding to the front guide groove (2) and is movably engaged with the front guide groove (2). (8) is a rear shelf that is formed to have a size corresponding to the rear support portion (3) and is supported by the rear support portion (3), and accommodates the front shelf (7) that has moved to the front and moved. A part (9) and a support shaft (10) projecting downward and pivotally supported by the rotation support part (4) are provided. Reference numeral (11) is a telescopic shelving device having the front shelf (7) and the rear shelf (8) as main constituent members.

The conventional telescopic shelf device of the refrigerator / freezer is constructed as described above, and when the telescopic shelf device (11) is extended and used, the front shelf (7) is arranged at the forward position and the front guide groove ( 2) The rear shelf (8) is supported by the edge portion, the support shaft (10) is pivotally supported by the rotation support portion (4), and is supported by the rear side support portion (3) to the state shown in FIG. Will be placed. Further, when the telescopic shelf device (11) is used by reducing it, the front shelf (7) is retracted through the front guide groove (2) and stored in the storage portion (9) of the rear shelf (8). , A shelf which is almost half the size of only the rear shelf (8) is constructed as shown in FIG.

Further, when the telescopic shelving device (11) is not used, the front shelf (7) is retracted through the front guide groove (2) to move the rear shelf.
The rear shelf (8) is accommodated in the accommodation section (9) of (8), and in this state the support shaft
It rotates as shown in FIG. 33 through (10) and the rotation support part (4). Then, as shown in FIG. 34, the support shaft (10) is attached to the blocking portion.
(6) The rear shelf (8) accommodating the front shelf (7) is moved down to the corresponding position, and the rear shelf (8) is arranged in the vertical position, that is, the retracted position.
