A cooler 14 and a blower 16 that constitute a refrigeration cycle of the cooling device are installed in the duct 11, and the machine room 17 formed below the bottom wall 6 </ b> B of the heat insulating wall 6 is refrigerated together with the cooler 14. A compressor 18, a condenser 19, a condenser blower 21, and the like constituting the cycle are installed.
[0014]
And the shelf apparatus 2 is constructed over the upper and lower stages in the storage chamber 9 on the front side of the partition plate 8. Each shelf device 2 is composed of a pair of brackets 22, 22, a shelf plate 3, a reinforcing plate 23, a slide rail 24, a stopper 4, and the like. In this case, shelf posts 26, 26 are vertically attached to the left and right sides of the partition plate 8, and a plurality of locking holes 27,.
[0015]
And the nail | claws 28 and 28 of the rear edge of both brackets 22 and 22 are detachably latched by the latching hole 27 of predetermined height. The slide rail 24 is attached to the bracket 22 in the front-rear direction, and the shelf board 3 is attached to and held by the left and right slide rails 24, 24. The shelf board 3 is supported by the slide rails 24 and 24 so as to be movable back and forth with respect to the brackets 22 and 22. The shelf 3 is made of a heat conductive plate such as a normal steel plate, stainless steel, or aluminum plate.
[0016]
The reinforcing plate 23 is screwed between the brackets 22 and 22. Here, the reinforcing plate 23 reinforces the shelf device 2 so that the entire shelf device 2 does not bend when the shelf plate 3 is pulled out forward of the storage chamber 9. The reinforcing plate 23 faces the shelf plate 3 below the shelf plate 3 with a predetermined gap, and a cool air passage 31 is formed between them. Further, the front end of the reinforcing plate 23 ends before the front end of the shelf plate 3, and an air outlet 32 is formed between the front and rear sides of the reinforcing plate 23 and communicates with the front end of the cool air passage 31.
[0017]
Further, the partition plate 8 at a position corresponding to the rear end of the cold air passage 31 has a plurality of through holes 33... Formed by punching on the left and right sides. It communicates with the duct 11 on the downstream side of the blower 16.
[0018]
Furthermore, the front end of the reinforcing plate 23 is formed with a bent portion 23 </ b> A that is bent upward in a U shape. Further, shafts 36 and 36 are attached to both sides of the front portion of the lower surface of the shelf plate 3, and the stopper 4 is pivotally supported on the shafts 36 and 36.
[0019]
Each stopper 4 is formed with a hook-like portion 4A on the inner side of the inner portion, and further, the inner side of the hook-like portion 4A is formed as an inclined surface 4B that narrows outward, and the shelf board 3 is accommodated in the storage chamber 9. In this state, the hook-shaped portion 4A is in a positional relationship to be detachably engaged with the bent portion 23A of the reinforcing plate 23. Further, the front end of the stopper 4 protrudes slightly forward from the shelf 3.
[0020]
Further, a leaf spring 41 is attached to the outer surface of each stopper 4, and the leaf spring 41 is in contact with the slide rail 24. The leaf spring 41 constantly biases the stopper 4 inward.
[0021]
In the state in which the shelf 3 is stored in the storage chamber 9, the stopper 4 is urged by the leaf spring 41, and the hook-like portion 4 </ b> A engages with the bent portion 23 </ b> A of the reinforcing plate 23. As a result, the shelf board 3 is not moved inadvertently.
[0022]
When the product is replenished on the shelf board 3 and the front end portions of the stoppers 4 and 4 are turned against the urging force of the leaf spring 41, the hook-like portion 4A is released from the bent portion 23A. Come off. In this state, if the shelf 3 is moved forward by the slide rail 24 and pulled out to the front, the product can be easily replenished.
[0023]
When the work is finished, if the shelf plate 3 is pushed in the direction of the storage chamber 9, the inclined surface 4B of the stopper 4 will eventually come into contact with the front surface of the bent portion 23A of the reinforcing plate 23, so that the stopper 4 is rotated along the inclination. The When the shelf plate 3 is stored in a predetermined position in the storage chamber 9, the hook-like portion 4 </ b> A of the stopper 4 moves to the rear side of the bent portion 23 </ b> A. The hook-shaped portion 4A is engaged with the bent portion 23A of the reinforcing plate 23 again.
[0024]
When the compressor 18 and the blower 16 of the cooling device are operated, the cooler 14 exhibits a cooling action. The cold air in the duct 11 cooled by the cooler 14 is sucked up by the blower 16 and blown upward, and is eventually discharged into the storage chamber 9 from the uppermost cool air discharge port 12.
[0025]
Further, a part of the cool air rising in the duct 11 flows into the cool air passage 31 of the shelf device 2 from each through hole 33... And moves forward through the cool air passage 31 to blow the front end. The air is blown downward from the outlet 32. At this time, the bent portion 23A is formed at the front end of the reinforcing plate 23, and the cold air passage 31 is narrowed at this portion, so that the cold air blown out from the outlet 32 is rectified and the flow velocity is increased.
[0026]
The cold air discharged or blown into the storage chamber 9 is finally circulated back to the duct 11 from the cold air inlet 13 (indicated by an arrow in FIG. 2).
On the other hand, the presser 5 is attached to the shelf column 26 on the upper side of the bracket 22. The presser 5 is configured by bending a metal plate or integrally molding a hard synthetic resin. As shown in FIG. 6, a main body 42 and a handle piece 43 protruding forward from the upper edge of the main body 42, An insertion piece 44 that protrudes rearward from the upper side edge of the main body 42 and a pressing piece 46 that protrudes laterally from the side edge of the main body 42 below the insertion piece 44 are integrally provided.
[0027]
Here, it is assumed that the pressing tool 5 of FIG. 6 is attached to the left shelf column 26 and the one attached to the right shelf column 26 has a symmetrical shape with that of FIG. Further, a drop prevention portion 45 extending upward is formed at the rear portion of the insertion piece 44, and has a shape that can be inserted into and removed from the locking hole 27 of the shelf column 26.
[0028]
With such a configuration, the holding piece 43 of the presser 5 is held, and as shown in FIG. 7, obliquely upward into the locking hole 27 directly above the locking hole 27 where the uppermost claw 28 of the bracket 22 is locked. The fall prevention part 45 is inserted into the locking hole 27 in an inclined state, and the handle piece 43 can be inserted horizontally by turning around the front end of the fall prevention part 45 and at the time of insertion / removal. Can be easily performed by performing an operation opposite to that at the time of insertion.
[0029]
At this time, by setting the position of the pressing piece 46 as described above, the pressing piece 46 comes into contact with or substantially contacts (very close to) the upper surface of the bracket 22. Thereby, when the shelf board 3 is pulled forward, even if the center of gravity moves forward, the claw 28 of the bracket 22 is lifted and the rear portion of the bracket 22 does not float.
[0030]
Further, since the insertion piece 44 of the presser 5 can be freely inserted into and removed from the locking hole 27 of the shelf column 26, it can be easily attached and detached when the attachment position of the shelf device 2 is changed. Since the shelf column 26 is inclined so that the upper part is rearward as shown in FIG. 3, the main body 42 of the presser 5 is held in close contact with the front surface of the shelf column 26. Therefore, the presser 5 does not come off due to vibration or the like.
[0031]
In the embodiment, the present invention is applied to an open showcase having a so-called movable shelf. However, the present invention is not limited to this, and the present invention is also effective for a normal shelf apparatus.
[0032]
【The invention's effect】
As described above, the presser can be easily inserted, and the presser piece can be brought close to or in contact with the upper surface of the bracket of the shelf device. Since the support member that can prevent the insertion piece from falling off the locking hole and falling can be easily reinforced to a predetermined strength, it is possible to appropriately cope with a product placed on the deck pan.
