Foam body plate for showcase {BACK PLATE OF FOAMING BODY FOR SHOWCASE}

The present invention relates to a foam body thick plate for a showcase, and in particular, to prevent the leakage of the foam liquid of the foam body for the showcase, to cushion the foam pressure and to remove the step with the trauma plate after foaming It relates to a foam body thick plate.

In general, the showcase is a facility for displaying and storing foodstuffs such as vegetables, fruits, and beverages that require refrigeration, and is widely used in large supermarkets and supermarkets due to its convenience.

These showcases may be classified into open and closed types according to the products to be displayed, or may be classified into multistage, flat, flat, and large types according to the type of showcase. In the case of the multistage, the foam body is installed in the lower case.

Specifically, the foam main body is a heat insulating material in which a foamed resin is injected therein, and serves to keep the temperature of the showcase constant by blocking heat exchange between cold and outdoor air as much as possible by blocking the lower case from which cold air flows to the outside.

On the other hand, the showcase is conventionally installed only in large marts, department stores and the like, but in recent years has been widely distributed in small marts, supermarkets, etc., the necessity to produce the above-described foam body is also small.

However, as shown in FIG. 1, the conventional foam body 10 is formed of a front part 10a, a bottom part 10b, and a rear part 10c in a pre-calculated size to suit the size of an existing large store. Jig (not shown) equipment for pressurizing each part upon foaming was also custom-made in size and shape suitable for this.

Therefore, in order to produce a small showcase according to the recent trend, there was a problem of redesigning the jig facility. That is, in the case of a small showcase, since the depth, that is, the length from the outside to the inside is short, the bottom part 10b of the foam body should also be short. Because there is only one, existing jig equipment customized for the large showcase cannot be used as it is.

As a result, investment costs for new jig facilities are generated, and even if the cost problem is solved, there are bounded limitations in implementing the showcase in various sizes.

On the other hand, in order to solve the above problems may be considered a method of foaming by installing a foamed wood in the rear end of the bottom portion (10b), when the foamed wood joints with the foam body is not maintained airtight foaming liquid It is not preferable because there is a problem of leakage or expansion of the foam body when foaming.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a foam body thick plate for a showcase that can prevent the leakage of the foam liquid generated during the foaming of the foam body for the showcase.

In addition, another object of the present invention is to provide a foam body thick plate for the showcase that can buffer the large pressure generated during foaming.

Another object of the present invention is to provide a foam body thick plate for the showcase that can minimize the assembly tolerance of the foam body.

As a means for solving the above technical problem,

The present invention is a thick plate coupled to the rear end opening of the foam body for showcase comprising an inner plate and an outer plate, the upper surface portion coupled to the inner plate, the support portion extending downward from the upper portion and the support portion Consists of a lower surface portion extending forward and coupled to the trauma plate, the upper surface portion is provided with a foam body back plate for the showcase, characterized in that a soft portion for elastically supporting the inner plate.

In this case, the support portion is preferably formed with a buffer portion curved inwardly.

In addition, the lower surface portion is preferably formed higher by the thickness of the trauma plate than the lower end of the support portion.

According to the present invention, by forming a double-extruded structure in which a soft soft portion protrudes on the upper surface of the rigid, the gap with the inner plate forming the foam body is hermetically blocked to prevent leakage of the foaming liquid during foaming.

In addition, by forming a buffer portion curved inwardly in the support portion to buffer the high-pressure foaming pressure to prevent expansion of the foam body, as well as to buffer the product weight after foaming can be expected.

In addition, it is possible to match the surface after foaming without irregularities by giving a step by the thickness of the trauma plate to the formation position of the lower surface portion.
