Abstract

PURPOSE:To check a rise in the temperature of a storage chamber without impairing operability of opening or closing a transparent door by a method wherein the transparent door is made up of a surrounding door frame and a transparent glass fitted into the door frame and a light shielding plate is placed on the transparent glass between the glass and the top surface of the door frame free to load or unload. CONSTITUTION:In a low temperature display case, when it is exposed to direct shining of the sun, a light shielding plate 25 is placed on a transparent glass 26 of transparent doors 21 and 21 to shield the incidence of the sun shine from the transparent doors 21 and 21, which allows the checking of a rise in the temperature within a storage chamber 9 by the incidence of the direct sun shining. Here, the light shielding plate 25 is placed between the transparent glass and a door frame 23 of the transparent door 21 and hence, the transparent doors 21 are so arranged to slide mutually or may be arranged, to be housed on the undersurface of a top board 17 of a heat insulating box or the like. If so, the light shielding plate 25 is kept from blocking the sliding of the transparent doors 21. This eliminates the need for the removal of the light shielding plate 25 when the transparent doors 21 are opened or closed thereby improving operability. In addition, a gap for inserting fingers is formed between the light shielding plate 25 and the door frame 23 thereby facilitating the removal of the light shielding plate 25.

The rear wall 4 of the heat insulating box 7 extends higher than the front wall 2 and an opening 8 is formed from the upper end of the rear wall 4 to the upper end of the front wall 2. A storage chamber 9 opened upward through the opening 8 is formed inside the heat insulating box 7, and a cooling device (not shown) is provided on the outer surface of the inner box 11 that forms the peripheral surface of the storage chamber 9. The cooling pipe is provided, and the inside of the storage chamber 9 is cooled to a predetermined freezing temperature via the inner box 11 by the cooling action from the cooling pipe.

The upper ends of the left and right side walls 6, 6 are slanted forward and gently from both sides of the rear wall 4 to the front wall 2.
Guide rails 12, 12 are formed on the upper surface of the guide rail 12 on both sides of the opening 8 and are inclined downward toward the front. Also,
A handrail 13 is attached to the upper end of the front wall 2 in front of the guide rail 12 so as to extend across the left and right, and an upper end of the rear wall 4 is located above the guide rail 12 and the rear sash 1 is provided.
4 is attached across the left and right. Further, a middle sash 16 that is located above the guide rail 12 and extends laterally is attached to the front upper side of the upper end of the rear wall 4. Then, after that, a translucent top plate 17 in which advertising characters and the like are printed on a colored glass plate is fitted between the sash 14 and the middle sash 16.

As a result, the opening 8 is actually opened in front of the sash 16. A middle rail 18 is provided between the guide rails 12 and 12 so as to divide the opening 8 into the left and right sides.
A transparent door 21 as shown in FIG. 3 is placed on the guide rails 12 and 12 and the middle rail 18 so as to be slidable right and left.

The transparent door 21 is composed of a door frame 23 having a handle 22 on the upper surface of the front side, and a transparent glass 26 fitted into the door frame 23 via a flexible packing 24 around the door. A heat ray reflective film is attached to the upper surface or the lower surface of the transparent glass 26. The door frame 23 has a predetermined thickness dimension thicker than the transparent glass 26,
Therefore, a predetermined space is formed between the upper surface of the transparent glass 26 and the upper surface of the door frame 23. In addition, the packing 24
A fin 27 is formed on the rear side of the door frame 23 so as to extend downward to the left and right, and a stopper 28 protruding downward is screwed to the rear surface of the rear side of the door frame 23.

On the other hand, a space is formed between the top plate 17 and the guide rails 12, 12 and the middle rail 18 so that the transparent doors 21 and 21 can pass therethrough, and the left and right sides are located above and above the front end of the rear wall 4. A fluorescent lamp 31 as an illuminating lamp is attached over the area. The fluorescent lamp 31 is located below the top plate 17 and below the guide rails 12, 12. Further, a translucent shade 32 is provided on the storage room 9 side of the fluorescent lamp 31, and the storage room 9 is partitioned from the space below the top plate 17 where the fluorescent lamp 31 is present.

The shade 32 is fixed to the mounting plates 33, 33 protruding inward from the left and right side walls 6, 6 with a screw 34 which can be detached from the storage chamber 9 side with a finger. The upper end is located below the middle sash 16. The front surface of the rear wall 4, which is below the shade 32, is inclined so that its upper portion projects forward, and a mirror 36 is attached to this inclined surface. The mirror 36 stands up while tilting forward toward the opening 8 at an angle such that the inside of the storage chamber 9 below is reflected when viewed from the front upper side.

The transparent doors 21 and 21 close the opening 8 with their front ends abutting against the handrail 13. At this time, the fins 27 of the packings 24 of the transparent doors 21, 21 come into close contact with the rear surface of the upper end of the shade 32, so that the storage chamber 9 is isolated from the space on the fluorescent lamp 31 side. The stopper 28 is a fin 27 of the packing 24.
Since it comes into contact with the shade 32 through the transparent doors 21, 2
1 is prevented from moving further forward and downward, and since the rear side of the door frame 23 is located between the middle sash 16 and the guide rails 12, 12, vertical movement is also prevented. Therefore, even when the transparent doors 21 and 21 are vigorously closed, the transparent doors 21 and 21 do not fall off the guide rails 12 and 12 and fall to the feet of the customer.

The transparent door 2 is provided by the stopper 28.
1, 21 cannot be removed as they are, but in the case of cleaning the rear surface of the transparent glass 26 of the transparent doors 21, 21, the screw 34 is removed and the shade 32 is attached to the mounting plate 33.
Remove from 33. Then, if the front ends of the transparent doors 21, 21 are lifted upwards, they can be easily removed.

Next, when the transparent door 21 is pushed up along the guide rail 12 and the middle rail 18 in order to deliver a product such as ice cream, the transparent door 21 moves to the lower side of the top plate 17 and is stored. , The opening 8 is opened. As a result, the opening 8 in front of the top plate 17 can be opened and closed by the doors 21, 21. At this time, since the products already stored in the storage room 9 are reflected in the mirror 36, the vacant portion can be easily found, the display work can be smoothly performed, and the customer can take out the products. Can also be easily selected. Further, when the inside of the storage room 9 is viewed from the upper front side, the products in the storage room 9 below the mirror 36 are reflected in a wide range on the mirror 36. As a result, the products are displayed as if they are displayed in the back of the rear wall 4, which makes it possible to display the products with a depth. Become so.

On the other hand, reference numeral 25 is a light shielding plate which is appropriately provided on the transparent doors 21 and 21. The light shielding plate 25 is a plate body having a structure in which a synthetic resin plate is sandwiched between aluminum plates, and cannot transmit light. The thickness of the light shielding plate 25 is equal to or smaller than the distance between the upper surface of the transparent glass 26 of the transparent door 21 and the upper surface of the door frame 23, and
The outer size of the packing 24 is smaller than the inner size of the packing 24. Further, the four corners of the light shielding plate 25 are notched so as to be curved with a predetermined radius to form curved portions 25R.

By the way, the low temperature showcase 1 is installed in a store, and therefore, in the daytime on a sunny day, direct sunlight enters the storage room 9 through the transparent glass 26 of the transparent door 21. Of course, the heat ray reflective film is attached to the transparent glass 26 as described above, but this is not sufficient when exposed to strong direct sunlight, and the temperature in the storage chamber 9 rises.

In this case, the light shielding plate 25 is attached to the transparent door 2
It is detachably mounted on the transparent glass 26 of 1 and 21. At this time, since the light shielding plate 25 has the above-described size, it is housed inside the packing 24 of the transparent door 21 and its upper surface is flush with or lower than the upper surface of the door frame 23. By placing the light shielding plate 25, the transparent door 2
Direct sunlight cannot enter from the transparent glass 26 of No. 1, and the temperature rise in the storage chamber 9 is suppressed. Further, since the light blocking plate 25 does not protrude above the door frame 23, even if the transparent door 21 is pushed up as shown in FIG. 5 in the mounted state, the light blocking plate 25 will not be caught by the middle sash 16 or the rear sash 14. . Therefore, the transparent door 2 with the light shielding plate 25 placed thereon
Since the doors 1 and 21 can be opened and closed, it is not necessary to remove the light shielding plate 25 each time the product is delivered, and the opening and closing operation of the transparent door 21 becomes significantly smoother than in the conventional case.

Here, the curved portions 25 are provided at the four corners of the light shielding plate 25.
Since the R is formed, the light shielding plate 25 is slightly separated from the door frame 23 and the packing 24 at the four corners of the transparent door 21, and a space for inserting fingers is formed between the light shielding plate 25 and the packing 24. Therefore, the light shielding plate 25 is not necessary, and the transparent door 21
When it is desired to remove the light shielding plate 25, the finger can be easily inserted into the back surface of the light shielding plate 25 by inserting the finger from the above interval, and the light shielding plate 25 can be easily attached and detached.

In the embodiment, the curved portions 25R are formed at the four corners of the light shield plate 25 so that the gaps are formed between the light shield plate 25 and the packing 24. However, the present invention is not limited to this.
It does not matter if you cut the appropriate places in 5 inward. Further, in the embodiment, the guide rails 12 and 12 are provided on both sides of the opening 8 and the transparent doors 21 and 21 are slid in the front-rear direction, and the top plate 17 is slid.
However, the present invention is effective even if a guide rail in the left-right direction is provided in the opening 8 and two transparent doors are slidably slid on each other. .
Further, the material of the light shielding plate 25 is not limited to the material of the embodiment, and any material that blocks light transmission may be used.

[0024]

As described in detail above, according to the first aspect of the invention, by placing the light shielding plate on the transparent glass of the transparent door when exposed to direct sunlight, the sunlight from the transparent door can be protected. The incidence can be blocked, and the temperature rise in the storage chamber due to direct sunlight or the like can be suppressed. At this time, since the light-shielding plate is placed between the transparent door and the upper surface of the door frame, the light-shielding plate will not be removed even if the transparent door is made to be a sliding type or is housed on the lower surface of the top plate of the heat insulating box. It does not interfere with the sliding of the transparent door. Therefore, it is not necessary to remove the light shielding plate each time the transparent door is opened and closed, and the opening and closing operability is remarkably improved.

Further, according to the invention of claim 2, in addition to the above, a space for inserting fingers is formed between the light shield plate and the door frame. Therefore, even when the light shield plate is removed, a finger is placed on the back surface of the light shield plate from this space. Can be easily inserted and removed.
