BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a showcase shelving device comprising shelves mounted on upright columns.

[0002]

2. Description of the Related Art Conventionally, in a showcase of this type, for example, Japanese Utility Model Publication No. 3-47185 (F25D17 / 0)
As shown in 8), vertical columns are erected at the four corners and the front and rear central portions of the interior of the refrigerator, and a plurality of engagement holes are formed in the columns at predetermined intervals in the vertical direction. Then, a structure in which a plurality of shelves are erected in the refrigerator by detachably inserting and engaging the ends of the shelves made of wires into the engagement holes.

However, when a cold air guide or the like is provided between the front and rear struts at the center as in the above-mentioned publication, the mounting surface of the shelf located on the side of the cold air guide needs to escape the cold air guide. The distance between the mounting surface and the column in the center will be separated. Hereinafter, details of such a conventional structure will be described with reference to FIG.

[0006] In FIG. 6, an engaging hole 1 is provided on a side surface of a front center support column 100 provided in a cabinet of a show case (not shown).
01 are drilled vertically at predetermined intervals.
1, a clip 102 serving as a shelf support member is detachably engaged and held, and a plurality of round hole-shaped engaging holes 104 are vertically formed at predetermined intervals on the front surface of the rear left and right columns 103.
The left and right side surfaces 105A, 105A and the front surface 105B are formed on the rear center column 105.
A plurality of elongate engagement holes 106 are vertically formed at predetermined intervals between the front surface 105A and the front surface 105B. Opposing wind direction plates 107 and 108 are provided at predetermined intervals between the front center support column 100 and the rear center support column 105, and a cooling unit (not shown) provided below through the space between these wind direction plates 107 and 108. The structure is such that cool air is discharged from the device into the refrigerator.

On the other hand, the shelf 109 is formed in a rectangular shape by spot welding a plurality of wires, and a support portion 110 spot-welded with a short wire projecting forward is provided on the left end of the front side 109A of the shelf 109. Is formed, and this support portion 1 is formed.
10 is a clip 10 attached to the front center column 100
2 and supported. A support portion 111 is formed at the right end of the front side portion 109A, and is placed and supported on a clip 102 of a front left and right support (not shown). Rear part 109 of shelf 109
B extends to the left as it is to form an engaging portion 113, which is inserted into and engaged with the engaging hole 106 of the rear center column 105, and the horizontal rail 109C on the front side of the rear side portion 109B projects to the right. After that, it is bent backward to form the engaging portion 114, and is inserted and engaged in the engaging hole 104 of the rear left and right support columns 103.

[0006]

Here, when the inside size of the showcase is expanded upward, a large amount of cool air must be discharged in order to circulate cool air uniformly in the store. The distance between the wind direction plates 107 and 108 is also enlarged. However, when the shelf 109 is located on the side of the wind direction plate 108, it is necessary to release the mounting surface 109D of the shelf 109 from the wind direction plate 108. It must be moved to the right, which is the direction away from 100, 105.
Therefore, the dimension of the front side portion 109A between the vertical side portion 109E and the support portion 110 becomes longer, and in this state, the product is placed on the shelf 10A.
9 on the front edge 109 of the shelf 109 by its weight.
A is greatly bent downward, and there has been a problem that it is extremely difficult to put products in and out.

Further, in order to make the shelf 109 slide back and forth, instead of the clip 102, a rail serving as a shelf support member for slidably supporting the vertical side portion 109E is provided between the front and rear central pillars 100 and 105. Also in the case of attachment, in the conventional structure shown in FIG. 6, the wind direction plate 108 hinders the rail from being brought close to the front and rear center supports 100 and 105. Therefore, the rail is elongated from the rail toward the supports 100 and 105. The legs must be extended, and when a load similar to that described above is applied to the shelf, the rails themselves will bend this time, which again causes a problem that it is difficult to put products in and out.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional technical problem, and it is possible to reduce the amount of bending of a shelf or a shelf supporting member even when a column and a mounting surface of the shelf are separated from each other. It is an object of the present invention to provide a showcase shelving device that can be used.

[0009]

On the front surface of the rear left and right columns 12, a plurality of round engaging holes 41 are vertically formed at predetermined intervals. Furthermore,
The rear central column 13 is formed by bending a vertically long steel plate at four locations to form left and right side surfaces 13A, 13A and a front surface 13B. A long hole is formed between the left and right side surfaces 13A, 13A and the front surface 13B. , A plurality of engaging holes 42 are vertically formed at predetermined intervals.

On the other hand, the shelves 2 and 27 are formed in a rectangular shape by welding a plurality of wires. Since the shelves 2 and 27 have a symmetrical shape, only the shelf 2 will be described. Shelf 2
Support portions 43 and 44 projecting forward from the front side 2A of the shelf 2 are formed at the front left and right ends of the shelf 2, and the rear side 2
B extends to the left as it is to form the engaging portion 46. The horizontal rail 2C on the front side of the rear side 2B protrudes rightward and is bent rearward to form the engaging portion 47. These front and rear sides 2A, 2B, and vertical sides 2D, 2
The area surrounded by E is the mounting surface 2F of the shelf 2.

When the shelf 2 (similarly for 27) is installed,
First, the engaging claw 32 is inserted into and engaged with the engaging hole 31 at a predetermined height, and the shelf receiver 3 is attached to the front center support 4. Next, the clip 40 is engaged with the engaging hole 36 of the shelf receiver 3. (The clip 40 is also attached to the front left and right supports.) Then, the engaging portion 46 of the shelf 2 is engaged with the engaging hole 42 of the rear center post 13.

Is located. Therefore, since the vertical side portion 2D of the shelf 2 and the clip 40 come close to each other, the vertical side portion 2D
Even if the distance to 3 is shortened, the vertical side portion 2D is located on the right side without being obstructed by the wind direction plate 24, and the mounting surface 2F can sufficiently escape the wind direction plate 24. Therefore, even if a large number of products are placed on the mounting surface 2F of the shelf 2, the amount of downward bending of the front side 2A of the shelf 2 is reduced, and the products can be delivered smoothly.

FIG. 5 shows another embodiment of the present invention. In FIG. 5, the same reference numerals as those in FIGS. 1 to 4 denote the same components. In this case, the shelf 2 has a mounting surface 2F in which a plurality of steel wires are fixed to a rectangular peripheral side 2G, and a central portion is bent upward at the upper surface on both left and right sides of the peripheral side 2G. The product fall prevention portion 2H is spot-welded. Further, a stopper portion 2S that descends downward in a substantially Z shape and protrudes outward is similarly attached to the lower surface on both sides of the rear side of the peripheral side 2G. Also, the clip as a shelf support member has been deleted, and instead a pair of rail members 51, 5
1 is prepared.

The rail members 51, 51 are made of a synthetic resin and are bilaterally symmetrical, and have a sliding surface 52 extending forward and backward on the upper surface and a groove 5 opened laterally along the lower side.
3 are formed. Further, an engagement claw portion 54 is formed outside the front end of the rail member 51, and an engagement protrusion 56 projecting rearward is formed at the rear end of the rail member 51. On the other hand, an auxiliary plate 58 having a plurality of round hole-shaped engaging holes 57 formed at predetermined intervals is provided on the front surface of the rear center column 13.

With the above arrangement, the rail members 51, 51
The engaging projections 56 are inserted into the engaging holes 57 of the auxiliary plate 58 and the engaging holes 41 of the rear left and right columns 12 from the front, respectively. Then, the engaging claw 54 at the front end is engaged with the shelf support 3. In the hole 36,
In addition, the rail members 51 and 51 are mounted in the refrigerator compartment 22 by engaging with engagement holes of the front left and right columns (not shown).
Next, the stopper portion 2S of the shelf 2 is inserted into and engaged with the groove 53, and the left and right ends of the peripheral side 2G are slidably mounted on the sliding surface 52, whereby the shelf 2 is moved to the rail members 51, 51. It is slidably mounted in the front and rear direction. The stopper portion 2S contacts the front end of the groove 52 when the shelf 2 is pulled out to prevent the shelf 2 from falling off.

At this time, the engagement hole 36 of the shelf receiver 3 is open in the opening direction of the engagement hole 31 of the front center column 4 so that the left rail member 51 is connected to the front center column 4. They will be separated sideways. Therefore, the engagement claw 54
Is formed on the outer surface of the rail member 51,
Is located on the left side without being disturbed by the wind direction plate 24,
It is possible to sufficiently escape the wind direction plate 24. Therefore,
There is no need to extend the legs to the left from the rail member 51 to form the engaging claw portions, and thereby the rail member 51 is not required.
Since a decrease in the strength of itself is prevented, even when a large number of products are placed on the mounting surface 2F of the shelf 2, the amount of downward bending of the rail member 51 is reduced, and the shelf 2 is pulled out and delivered. Can be performed smoothly.

[0025]

As described above in detail, according to the present invention, a shelf receiving side engaging hole having the same height as the column side engaging hole is formed on the front surface of the shelf receiving member attached to the column side engaging hole. Since the shelf receiving side engaging hole is separated in the opening direction of the column side engaging hole, the shelf supporting member supporting the shelf end is separated from the column,
The shelves can be brought close to the mounting surface. Therefore, even when the mounting surface of the shelf is separated from the support, there is no need to extend the shelf end or the shelf support member to the support. This makes it easy to get out.
