Description

[Detailed description of the invention] [Technical field of the invention] The invention proposes that the front shelf and the rear shelf be arranged one behind the other in the housing, or that they overlap vertically in the rear half, or that both the shelves be placed on the back. The present invention relates to a shelf that can be placed in an upright position and can be selected from three states depending on the shape of the articles to be stored inside the case.

[Technical background of the invention] In a case equipped with this type of shelf, such as a refrigerator,
When storing tall items on the front side, if you move the front shelf to the rear, it will overlap the bottom side of the rear shelf. The front shelf and the rear shelf, which are vertically overlapped in the section, are rotated upward to stand up along the back surface of the housing.

[Problems with background technology]

However, as mentioned above, when returning the front shelf and rear shelf that were in the upright state to the horizontal state, if the front shelf located on the near side is rotated toward the front, the rear shelf will remain in the upright state, and the front shelf will remain in the upright state. Following the rotation of the rear shelf, it is necessary to rotate the rear shelf forward again.
It was troublesome to handle.

[Purpose of invention]

The present invention was developed in view of the above circumstances, and its purpose is to ensure that both the front and rear shelves are moved to the front side in one operation when returning the front and rear shelves from an upright position to the horizontal position. The purpose is to provide a shelf that can be rotated and is easy to handle.

[Summary of the idea]

The present invention provides a rear shelf with a hook member protruding downward, a front shelf with a hook member that engages with the hook member when the front shelf and rear shelf are in an upright state, and It is characterized by being located in front of the center of rotation of the rear shelf.

[Example of idea]

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes an inner box of the refrigerator as a housing, and shelf-supporting convex portions 2 are formed on the left and right side surfaces (only the left side is shown) of the inner box in a substantially horizontal state. 3 is the rear shelf, which has two support shafts 3 oriented in the left and right direction.
a, 3b, a plurality of small-diameter receiving members 4 oriented in the front-rear direction perpendicular to these are fixed by welding or the like at predetermined pitches, and both ends of the support shafts 3a, 3b are formed into convex parts. When placed on the receiving portions 5 and 6 provided in the inner box 1, it assumes a substantially horizontal state within the inner box 1. 7 is a front shelf, which, like the rear shelf 3, has two supporting shafts 7a and 7b oriented left and right, and a plurality of small diameter support members 8 oriented in the front and back direction perpendicular to these shafts at a predetermined pitch. The front support shaft 7a is fixed by welding or the like.
A decorative frame 9 made of plastic and having a substantially U-shaped cross section is fitted onto the outer periphery of the frame. Now, 10 is a guide part formed in the convex part 2 and oriented in the front-rear direction, the front half of which is located approximately on the same horizontal line as the receiving parts 5 and 6, and the latter part is further than the receiving parts 5 and 6. It is in a substantially horizontal state downward, and has an inclined part 10 in the middle part.
It has a. Then, the support shaft 7 of the above-mentioned front shelf 7
Both ends of a and 7b are inserted into the guide portion 10 so as to be slidable in the front-back direction. Therefore, when the front shelf 7 is moved rearward, the front shelf 7 is guided by the guide portion 10 so as to overlap the lower surface side of the rear shelf 3. In this case, the rear end of the guide part 10 is located forward of the receiving part 6 that supported the support shaft 3b on the rear side of the rear shelf 3, and the support shaft 7b comes into contact with the rear end of the guide part 10. When the front shelf 7 is moved backward until
The support shaft 7b of the rear shelf 3 is positioned in front of the support shaft 3b of the rear shelf 3. Reference numeral 10b denotes a chevron-shaped convex portion formed near the front end of the guide portion, which is located behind the support shaft 7a when the front shelf 7 is moved forward, so that the front shelf 7 moves rearward during normal loading and unloading of food, etc. I'm trying to make sure it doesn't get moved. Further, reference numeral 10c is a groove portion facing the lower end of the inclined portion 10a and communicating with the guide portion 10 and opening upward. on the other hand,
Reference numeral 11 denotes a hook member welded to the receiving materials 4, 4 of the rear shelf 3, which is located approximately in the center of the receiving materials 4, 4 in the front-rear direction and protrudes downward from the rear shelf 3. 12
is a hooking member welded between the receiving members 8, 8 of the front shelf 7, and this is located a predetermined distance ahead of the central portion of the receiving member 8 in the front-rear direction.

Next, the operation of the above configuration will be explained. Front shelf 7
In the state shown in FIGS. 1 and 2 in which the front shelf 7 and the rear shelf 3 are moved forward, the receiving materials 8 of the front shelf 7 and the receiving materials 4 of the rear shelf 3 are positioned approximately on the same horizontal plane. It can be placed. Next, when storing large items in the front half of the inner box 1, when the front shelf 7 is pushed backward, the support shafts 7a and 7b are guided along the guide part 10, and the shafts 7a and 7b are guided under the rear shelf 3. They are stored so that they overlap on the sides (see Figure 3). In this state, the support shaft 7b is in contact with the rear end of the guide portion 10, and the support shaft 7a is in contact with the rear end of the inclined portion 10a and is located directly below the groove portion 10c.

Therefore, when storing items with a large height in the entire inner box 1, the front shelf 7 and the rear shelf 3 are stacked on top of each other as shown in FIG. 4, and then the decorative frame 9 of the front shelf 7 is Grasp your hand and rotate it upwards (in the direction of arrow A) to remove the rear shelf 3.
is made to lean against the back part of the inner box 1, and the front shelf 7 is made to lean against the rear shelf 3. At this time, the rear shelf 3 is rotated around the support shaft 3b placed on the receiving part 6, and the support shaft 3a escapes upward from the receiving part 5, and the front shelf 7 is moved from the rear end of the guide part 10. The support shaft 7a is rotated about the support shaft 7b located at the center, and the support shaft 7a escapes upward through the groove portion 10c. The support shaft 3b that is the center of rotation of the rear shelf 3 and the support shaft 7b that is the center of rotation of the front shelf 7 are vertically different, and the support shaft 7b is the center of rotation of the rear shelf 3.
is located on the front side of the support shaft 3b, so the rear shelf 3 and the front shelf 7 may be tilted further back than the upright position as shown in Fig. 4 and placed against the back of the inner box 1. You can prevent it from falling forward.
Moreover, as the rear shelf 3 and the front shelf 7 rotate, the hook member 12 moves relatively toward the hook member 11, so that the front shelf 7 and the rear shelf 3 move upward at a predetermined angle. When rotated, the hook member 12 engages with the hook member 11, and the hook member 12 engages with the hook member 11 even in the upright state shown in FIG. Therefore, when you put your hand on the decorative frame 9 of the front shelf 7 and rotate it forward (in the opposite direction of arrow A) from the standing state shown in FIG. 4, only the front shelf 7 does not rotate.
The rear shelves 3 rotate forward all at once, and eventually become horizontal as shown in FIG. At this time, while the rear shelf 3 and front shelf 7 are returning from the upright state to the horizontal state, the hook member 12 comes off from the hook member 11, so the front support shaft 3a of the rear shelf 3 is received by the receiving part 5 and is leveled. Even when the front shelf 7 returns to its normal position, there is no risk that the hook member 12 of the front shelf 7 will remain hooked to the hook member 11 and the rear shelf 3 will not return to the horizontal state. Both can be returned to the horizontal state. Incidentally, in order to obtain the state shown in FIG. 2, the front shelf 7 may be moved forward along the guide portion 10 from the state shown in FIG. 3, contrary to the above.

According to the above configuration, when the front shelf 7 and the rear shelf 3 in the upright state are brought back to the horizontal position, if only the front shelf 7 is rotated forward by hand, the rear shelf 3 will follow and rotate all at once. Since it moves, the front shelf 7 and the rear shelf 3 can be returned to the horizontal position with a single operation, making handling much simpler than the conventional structure. Moreover, when the front shelf 7 is moved rearward, the front shelf 7 is positioned on the lower side of the rear shelf 3, so the front shelf 7 is positioned on the upper side of the rear shelf 3. is different, inner box 1
When storing tall foods on the front side of the rear shelf 7
The front shelf 7 can be moved rearward with food still placed on it. Moreover, since the hook member 11 protrudes below the rear shelf 3, there is no fear that the hook member 11 will get in the way when food is placed on the rear shelf 3.

Furthermore, when the front shelf 7 is superimposed on the lower surface side of the rear shelf 3, the spindle 7b, which is the center of rotation of the front shelf, is positioned in front of the spindle 3b, which is the center of rotation of the rear shelf 3. Both shelves 3 and 7 can be tilted backwards to stand up against the rear surface of the inner box 1, and can be prevented from accidentally falling forward. Moreover, when the front shelf 3 and the rear shelf 7 are rotated downward from the upright position, the hook member 12 comes off from the hook member 11 during the rotation, so that the rear shelf 7 and the front shelf 7
When the hook member 12 is returned to the horizontal state, the hook member 12 is removed from the hook member 11, and therefore, the front shelf 7 can be moved forward by pulling the front shelf 7 as it is, providing excellent operability.

Note that the hooking member 12 does not necessarily have to be an independent structure; for example, a receiving member extending from side to side may be provided on the front shelf and a part of the receiving member may be used.
Furthermore, the hook member 11 and the hook member 12 may be replaced.

[Effect of idea]

As is clear from the above description, the present invention allows the front shelf to be moved rearward while food is still placed on the rear shelf, and the front shelf and rear shelf can be erected to a position where they are tilted backwards. The shelf will not fall forward accidentally. When the front shelf and the rear shelf, which have overlapped one another in an upright position, are returned to the horizontal position again, the hook member on the rear shelf and the hook member on the front shelf are engaged, so that the front shelf and the rear shelf are always fixed in one operation. Both shelves can be rotated toward the front, and when both shelves are returned from an upright state to a horizontal state, the hook member disengages from the hook member in the middle, making subsequent operations easier. Furthermore, since the hook member is provided so as to protrude downward, there is no fear that the hook member will interfere with putting in and taking out food, and other excellent effects are achieved.
