Description

[Detailed description of the invention] Conventional technology Conventionally, an extendable shelf device in a refrigerator that allows the shelf area to be changed as necessary is disclosed in, for example, Utility Model Publication No. 9822 of 1930 or Utility Model Publication No. 5546 of 1939. Are listed.

Problems to be solved by the invention In the above conventional products, the former has a shelf support that supports the front shelf on the underside of the rear shelf, making the front shelf slidable, while the latter has two shelf supports. Since the front shelf is configured to fit into the bottom of the rear shelf, both
When only the front shelf is pulled out from the stacked state of the front and rear shelves, a step is created between the front and rear shelves, resulting in a lack of stability when storing articles. For this reason, in the latter case, in order to make a flat plate with a full width that is flush with the entire width, it is necessary to remove the front shelf from the shelf holder and place it again, making it impossible to insert the front shelf under the rear shelf in this state. There are problems with stability and storage stability.

Means for Solving the Problem The front horizontal bars 6a of the rear shelf are positioned within the frame of the front shelf 5, and the vertical bars 5b of the front shelf 5 and the vertical bars 6c of the rear shelf 6 are alternately positioned, and the inner box The front and rear shelves are slidably and telescopically mounted flush on the shelf support portion 7 formed in the rear shelf 6.
A predetermined space is provided between the upper surface of the front horizontal crosspiece 6a and the lower surface of the vertical crosspiece 6c, and when the front shelf 5 and the rear shelf 6 are extended flush, the rear frame of the front shelf 5 and the front crosspiece of the rear shelf 6 6a are vertically overlapped with each other, and a locking groove 8 for locking the front horizontal crosspiece 6a of the rear shelf 6 to the shelf support portion 7, and projections projecting upward on the left and right sides of the front shelf frame 5a. 5c, and the height between the lower surface of the front horizontal beam 6a of the rear shelf 6 and the upper surface of the protrusion 5c of the front shelf 5 is configured to be larger than the height of the shelf support.

Embodiments Hereinafter, a detailed description will be given based on the illustrated embodiments. 1 is the refrigerator main body, 2 is an inner box forming the main body, 3 is an ordinary single shelf, and 4 is a retractable shelf according to this invention. 5 and a rear shelf 6. This extendable shelf has a shelf frame 5a formed in a rectangular shape and provided with upwardly projecting protrusions 5c on the left and right sides, and a front shelf 5 formed by a plurality of vertical bars 5b connected to the front and rear of this shelf frame. are doing. In addition, the rear shelf 6 has front and rear horizontal bars 6a, 6.
b are connected by a plurality of vertical bars 6c, and the horizontal bars 6a on the front side of the rear shelf are connected to the horizontal bars 6b via the rear side of the front shelf, and each vertical bar of the rear shelf 6 6
c are arranged alternately between the vertical bars 5b of the front shelf 5. Furthermore, the vertical bar 6 of the rear shelf 6
The front part of c is bent downward and fixed to the front horizontal bar 6a, and the upper surface of the front horizontal bar 6a of the rear shelf and the lower surface of the vertical bar 6c form a predetermined space, and the front shelf 5 is fixed to the front horizontal bar 6a in this predetermined space.
The rear side of the shelf frame 5a is located. That is, the front shelf 5
The rear side of the shelf frame and the front horizontal bar 6a of the rear shelf 6 overlap,
The upper surfaces of the front shelf 5 and the rear shelf 6 become flush. 7 is a shelf support portion formed opposite to the left and right side walls of the inner box 2;
The left and right sides of the shelf frame of the front shelf 5 and the left and right ends of the horizontal bars 6b of the rear shelf 6 of the telescopic shelf are placed on the lower surface of this shelf receiver. Reference numeral 8 denotes a rear shelf locking groove formed by recessing one step from the lower surface of the shelf receiving groove, and the front horizontal bar 6a of the rear shelf is locked in this locking groove. The height of the shelf support portion 7 is as follows when the telescopic shelf 4 is extended flush, that is, when the rear side of the shelf frame 5a of the front shelf and the front horizontal crosspiece 6a of the rear shelf overlap vertically. The lower surface of the front horizontal crosspiece 6a of the rear shelf and the front shelf 5
It is formed so that it is lower than the height formed by the upper surface of the protrusion part 5c provided on the left and right sides of the shelf frame 5a.

Function Next, to describe the function of this device, by sliding the front shelf 5 of the telescopic shelf 4 in its normal state backward along the shelf support 7, the state shown in Fig. 4 is achieved. . That is, the front shelf 5 and the rear shelf 6 are overlapped to form a half-width shelf. Furthermore, even if the rear side of the shelf frame 5a of the front shelf and the vertical crosspiece 6c of the rear shelf come into contact and slide when the front shelf 5 is slid forward and returned to the normal state, the front horizontal crosspiece 6a of the rear shelf is The left and right ends are locked in locking grooves 8 provided in the shelf support, and the rear shelf 6 does not slide forward together with the front shelf 5. Also, when sliding the front shelf 5 forward and returning it to the normal state, even if you pull it carelessly toward you, the upper surface of the projections 5c on the left and right sides of the shelf frame 5a of the front shelf 5 and the front horizontal crosspiece of the rear shelf 6 will be damaged. The height between the bottom surfaces of 6a is
Since the height is greater than the height of the shelf support part 7, when the extendable shelf 4 is in a normal state, it will not protrude ahead of a normal shelf. In addition, the front part of the vertical bar of the rear shelf is bent and formed, and the rear side of the shelf frame of the front shelf is located in the space between the front horizontal bar and this vertical bar, so when food is placed on the rear shelf. Since the load is also applied to the rear side of the shelf frame of the front shelf, the load applied to the front horizontal crosspiece of the rear shelf is reduced.
The front horizontal crosspiece of the rear shelf has the advantage that the wire diameter can be made thinner.

Effects of the invention Since the locking groove 8 for the rear shelf 6 is provided in the shelf holder 7, when the front shelf 5 is slid, the rear shelf 6 does not slide together, and the front shelf 5 can be kept in place. Even if you carefully pull it back to the normal state, when it becomes flush, the height of the shelf sliding part is higher than the height of the shelf holder, so it will be locked in the same predetermined position as a normal shelf, and it will slide smoothly. This has practical effects such as being able to perform sliding operations.
