Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a showcase having a reinforcing plate that connects a bottom heat insulating box, a rear heat insulating plate, and a leg portion and connects and reinforces the rear surface of each member.
[0002]
[Prior art]
In general, as shown in FIG. 6, a bottom heat insulating box 101 having a U-shaped cross section, a back heat insulating plate 103 disposed on an upper surface 101b of a back side rising portion 101a of the bottom heat insulating box, and the bottom heat insulating box There is known a showcase 109 having a structure in which a leg portion 105 arranged at a lower portion 101c of the 101 is connected and connected and reinforced through a reinforcing plate 107 on the back side of each member. In this type, the reinforcing plate 107 is attached to the bottom cross-section box body 101, the back heat insulating plate 103, and the leg portion 105 so as to protrude from the back surface.
[0003]
[Problems to be solved by the invention]
However, in the conventional configuration, the reinforcing plate 107 protrudes from the bottom cross-section box 101, the rear heat insulating plate 103, and the leg portion 105, so that the protruding reinforcing plate 107 is used for transportation and installation. For example, when transported by a transportation means such as a truck, there is a problem that the packing width becomes large, a loss occurs in the loading of the truck, and the distribution cost is increased.
[0004]
Therefore, an object of the present invention is to provide a showcase that can solve the problems of the above-described prior art and prevent the reinforcing plate from protruding.
[0005]
[Means for Solving the Problems]
The invention according to claim 1 comprises a bottom heat insulating box, a back heat insulating plate disposed on the upper surface of the back side rising portion of the bottom heat insulating box, and a leg disposed at the bottom of the bottom heat insulating box. In a showcase having a reinforcing plate that connects and reinforces these members on the back side of each member, the bottom heat insulating box or the back heat insulating plate includes an outer plate, an inner plate, and a foam heat insulating material filled therebetween. A reinforcing plate housing groove is provided in the bottom heat insulating box and the back heat insulating plate, and the reinforcing plate housing groove is formed by providing a recess in the outer plate, and a nut is formed on the inner surface of the outer plate. characterized in that fixed to and along the plate, the reinforcing plate is housed in the reinforcing housing groove, the lower fixed to Rutotomoni the reinforcing plate to the nut plate through a bolt fixed to the back of the legs And
[0006]
In the first aspect of the present invention, the bottom heat insulating box or the rear heat insulating plate is formed by an outer plate, an inner plate, and a foam heat insulating material filled between the outer plate, the bottom heat insulating box, and the rear heat insulating plate. A reinforcing plate housing groove is provided, the reinforcing plate housing groove is formed by providing a recess in the outer plate, and a nut plate is fixed along the inner surface of the outer plate, and the reinforcing plate is placed in the reinforcing housing groove. accommodated, because the rewritable fixed to the nut plate through a bolt at the bottom of the reinforcing plate is fixed to the back of the legs, since the depth of the reinforcing plate overlap in the depth of the reinforcing plate receiving groove, the reinforcement plate Can be prevented from protruding from the back. Further, since the nut plate is fixed along the inner surface of the outer plate, the reinforcing plate is sandwiched between the bolt and the nut plate and can be firmly fixed.

An upper bumper 29 is provided around the upper edge of the front panel 27, and a lower bumper 31 is provided around the lower edge.
[0016]
By the way, in this low-temperature round showcase 1, in order to keep the temperature of the interior 5 constant, a bottom heat insulation box 33 having a U-shaped cross section that shields heat from the outside at the bottom of the interior 5 As shown in FIG. 3, a rear heat insulating plate 35 disposed on the upper surface 33b of the rear side rising portion 33a of the bottom heat insulating box 33 is provided. A leg portion 37 is disposed on the lower portion 33 c of the bottom heat insulating box 33, and the bottom heat insulating box 33, the back heat insulating plate 35, and the leg portion 37 are connected to each other. Reference numeral 38 denotes a top heat insulating plate.
[0017]
As shown in FIG. 4, the bottom heat insulating box 33 and the rear heat insulating plate 35 are formed by an outer plate 39, an inner plate 41, and a foam heat insulating material 43 filled therebetween. 3, in order to reinforce the connection of the bottom heat insulating box 33, the back heat insulating plate 35, and the legs 37, the back surface 33 d of the back rising portion 33 a of the bottom heat insulating box 33, that is, the outside of the bottom heat insulating box 33. A reinforcing plate housing groove 45 is provided on the plate 39 and the back surface 35 a of the back heat insulating plate 35, that is, the outer plate 39 of the back heat insulating plate 35, and a reinforcing plate 47 that can be stored in the reinforcing plate housing groove 45 is provided.
[0018]
As shown in FIG. 4, the reinforcing plate accommodation groove 45 is formed in a quadrangular prism shape by providing a recess in the outer plate 39 and has a width W1 and a depth L1.
[0019]
The reinforcing plate 47 has a thickness T1, a width W2, and a depth L2, and is formed of a U-shaped member.
[0020]
In this embodiment, the width W1 of the reinforcing plate receiving groove 45 and the width W2 of the reinforcing plate 47 are formed substantially the same, and the depths L1 and L2 are also formed approximately the same.
[0021]
Via the reinforcing plate 47, the back surface 33d of the back rising portion 33a of the bottom heat insulating box 33 and the back surface 35a of the back heat insulating plate 35 are connected and reinforced. As shown in FIG. Since the back surface 33d of the body 33 is provided so as to be located inward by the depth L1 of the reinforcing plate housing groove 45 from the back surface 33d of the back surface rising portion 33a, as shown in FIG. It can be fixed to the back surface 37a of.
[0022]
4, the nut plate 49 is fixed along the inner surface of the reinforcing plate housing groove 45 of the outer plate 39 of the bottom heat insulating box 33 and the rear heat insulating plate 35, and the reinforcing plate 47 is the reinforcing plate. It is accommodated in the accommodation groove 45 and is fixed to the nut plate 49 via the bolt 51.
[0023]
The nut plate 49 has a thickness T2, a width W3, and a depth L3, is configured by a U-shaped member, and is formed between the outer plate 39 and the inner plate 41 of the bottom heat insulating box 33 and the rear heat insulating plate 35. When the foam heat insulating material 43 is filled, the outer surface 39 of the reinforcing plate housing groove 45 is temporarily fixed to the inner surface of the outer plate 39 of the reinforcing plate housing groove 45 in advance, and the volume of the foam heat insulating material 43 expands. It is provided so that it may adhere to the inner surface.
[0024]
This embodiment has the following effects.
[0025]
A reinforcing plate housing groove 45 is provided in the bottom heat insulating box 33 and the back heat insulating plate 35. A reinforcing plate 47 is housed and fixed in the reinforcing housing groove 45, and a lower portion 47 a of the reinforcing plate 47 is a leg portion 37. Since the depth L2 of the reinforcing plate 47 overlaps the depth L1 of the reinforcing plate receiving groove 45, it is possible to prevent the reinforcing plate 47 from protruding from the back surface.
[0026]
Since the reinforcing plate 47 is composed of a U-shaped member, the second moment of section is larger than that of the flat plate, and is difficult to bend.
[0027]
Since the nut plate 49 is fixed along the inner surface of the outer plate 39, the reinforcing plate 47 is sandwiched between the bolt 51 and the nut plate 49 and can be firmly fixed.
[0028]
As mentioned above, although this invention was demonstrated based on one Embodiment, it is clear that this invention is not limited to this.
[0029]
