Description

[Detailed Description of the Invention] (a) Field of the Invention The present invention relates to a shelf device used for placing articles in a storage such as a refrigerator.

(b) Background and problems with the background art Conventionally, shelves used in this type of storage, for example, refrigerators, are supported on both sides by rails formed on both side walls of the storage and are disposed in a removable manner. Shelves are usually movable back and forth using rails, but for example, when taking out items placed at the back, it is difficult to reach, so the shelves themselves have to be pulled forward a little to take out the items. Although it is desirable to do this, it has the disadvantage that a large frictional force is generated between the shelves on which the articles are placed and the rails, making it difficult to move them. Further, when the shelf is pulled forward, there is a risk that it will accidentally come off the rail and fall, so it was necessary to form a special stopper structure.

(c) Purpose of the invention The purpose of the invention is to provide a shelf device that has a simple structure, is easy to pull out, and is free from the danger of falling.

(d) Outline of the idea Rails are formed on both sides of the storage room, rollers are installed on both sides, and a frame consisting of a front edge, an upper edge, and a rear edge is formed on both sides, and legs protrude to both sides from the rear edge. A shelf is prepared in which the legs are slidably engaged with the rails, the frame is hung on rollers, and the shelf is constructed so as to be movable back and forth.

(e) Embodiment of the invention FIG. 1 shows a schematic side sectional view of a refrigerator 1 as an embodiment. The refrigerator 1 is formed by filling a heat insulating material 4 between an outer box 2 and an inner box 3 usually made of thermoplastic resin or the like. A machine room 7 is formed in the lower part of the refrigerator 1 in which a compressor 5 and a condenser 6 constituting a refrigeration cycle are installed. The refrigerator 1 has an opening at the front, and the opening is closed by a door body 8. Inside the refrigerator 9, a cold air passage 11 formed between a partition plate 10 and a back wall is provided with air contained in the above-mentioned refrigeration cycle. A cooler 12 is installed, and cold air from the cooler 12 is circulated into the refrigerator interior 9 by a blower 13. On both side walls of the inner box 3, there are rails 14 having grooves 14a extending substantially horizontally forward from the partition plate 10 portion as shown in FIG.
is integrally molded with the inner box 3. As shown in FIG. 3, front rollers 15 are rotatably fixed to the front side walls of the rail 14 by screws 16. 1
Reference numeral 7 denotes a reinforcing material provided on the heat insulating material 4 side of the inner box 3 into which the screw 16 is screwed.

18 is the shelf of the present application. Shelf 18 has horizontal main frame 19
An intermediate horizontal bar 21 located approximately in the middle of the front horizontal bar 20 and the shelf 18, respectively, and a plurality of wire-shaped vertical bars 22 are fixed to the front and rear sides by, for example, welding. At this time, the intermediate horizontal bar 21 is located approximately in the middle of the vertical bar 22, and the rear part of the vertical bar 22 is bent upward to fix the rear horizontal bar 23 to the end. The rear horizontal bar 23 protrudes to both sides, and a rear roller 24 serving as a leg is attached to an end of the rear horizontal bar 23 so as to be rotatable about the rear horizontal bar 23 as an axis. The main frame 18 has both sides bent upward on the outside from the outermost vertical bar 22a, and has a front side 25 and an upper side 2.
6 and a rear side 27 are formed.

The shelf 18 formed in this manner is installed in the refrigerator interior 9 by hanging the side frame portion 28 on the front roller 15 and slidably engaging the rear roller 24 on the rail 14. Here, a stop portion 29 is formed at the front end of the upper side 26 of the side frame portion 28 and is slightly bulged upward.
is located within this stop portion 29, and the shelf 18 is horizontally supported in a predetermined position. When taking out the article placed on the back of the shelf 18 from this state, the shelf 18
toward you, remove the front roller 15 from the stop portion 29, and pull it out forward. At this time, the shelf 18 is smoothly moved by the rotation of the front and rear rollers 15 and 24, and soon the front roller 15 moves to the rear side 27 of the side frame portion 28.
It will come into contact with and will no longer be pulled forward.
Here, the length of the rail 14 is set in advance so that the rear roller 24 is still supported by the rail 14 in this state. Thereby, there is no danger of the shelf 18 accidentally falling when it is pulled out.

Next, when installing or removing the shelf 18, the elasticity of the side frame portion 28 is used. At this time, the side frame portion 28 becomes a carrying handle, and the article can be easily carried even when it is placed thereon.

(f) Example of application of the invention Figures 5 and 6 show other embodiments.
Components in the figure with the same reference numerals as in FIG. 1 have the same functions. 1' is a so-called two-temperature refrigerator, and the interior is divided into a freezing compartment 31 and a refrigerating compartment 32 by a partition wall 30.
The cooler 12 is provided in a cooling chamber 33 in a partition wall 30. A partition member 34 is provided in the middle of the opening of the refrigerator compartment 32.
A wild field container 35 forming a so-called wild field room is housed in the lower part along with a field field door 36 so as to be freely delivered. Here, 37 and 38 are a freezer compartment door and a refrigerator compartment door, respectively. The refrigerator compartment 32 is provided with two upper and lower shelf shelves to which the present invention can be applied. The upper shelf 18 in Fig. 5 is suitable for storing wine, etc., so that the inner part of the rail 14' is slightly lower than the front roller 15, and the inner part of the rail 14' is slightly lower than the front roller 15, and from there it slopes upward and moves forward. It is formed to extend. With this configuration, when the shelf 18 is pulled out, the shelf 18 becomes horizontal.

Next, the lower shelf device is shown enlarged in FIG. In this case, since the shelf 18' is located behind the partition member 34 in the stored state, it cannot be pulled out forward. There, shelf 1
A sloped surface 39 that slopes upward is formed at the front part of the upper side 26' of the side frame portion 28' of the rail 14'', and a sloped portion 40 having the same angle as the sloped surface 39 is formed on the rail 14''. As a result, when the shelf 18' is pulled out forward, it is translated upward along the inclined surface 39 and the inclined part 40, so that the articles can be finally pulled out above the partition member 34 without falling.

FIG. 7 shows an example in which the present invention is applied to a display device such as a show case, in which the front roller 15 is positioned below the rail 14,
is inclined in the direction of the front roller 15. rail 14
A recessed part 41 is formed at the back so that the shelf 1 can be stored in the stored state.
The rear roller 24 of 8 falls into the concave portion 41 and is prevented from sliding downward. Furthermore, a locking protrusion 42 is formed at the front end of the shelf 18'' to prevent the placed articles from falling.

(g) Effects According to the present invention, the shelf can be moved smoothly, and articles placed at the back of the shelf can be easily taken out. or,
Since the drawer is restricted by the rear edge of the side frame, there is no risk of the shelf accidentally falling. Further, when the shelf is removed from the storage chamber, the side frame portion can be used as a handle, and articles placed thereon can be easily transported. Furthermore, the structure is simple and has great practical effects.
