Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a show case of a type in which the upper end of an article loading/unloading hole provided in the upper wall of a container portion is opened and closed by a sliding door.

Such cases are used, for example, for cold storage of articles. Therefore, the part of the case body that receives the articles, that is, the container section, is constructed using a heat insulating material, and generally includes a cooling device for cooling the inside of the container section. However, in addition to opening and closing the upper end of the article loading/unloading hole with a sliding door, the hole wall may also have a window with low insulation made of a transparent glass plate, etc., so the container section generally has sufficient insulation. This results in a lot of wasted energy.

Therefore, an object of the present invention is to provide a sliding door opening/closing show case which is provided with a transparent cover at the bottom of the article entry hole in addition to the sliding door, thereby improving the heat insulation effect.

A further object of the present invention is that as the sliding door is opened and closed, the cover automatically moves in a plane parallel to the sliding door in a direction perpendicular to the opening and closing direction of the sliding door to open and close the lower part of the article loading/unloading hole in the container section. The goal is to provide a show case with a sliding door that opens and closes.

According to the present invention, in the case where the upper end of the article loading/unloading hole provided in the upper wall of the container part having a heat insulating structure is opened and closed by a sliding door movable in a first direction, the sliding door is provided at the lower part of the article loading/unloading hole. A transparent cover plate is provided that is movably guided in a second direction perpendicular to the first direction within a parallel plane, and a transparent cover plate is provided that extends obliquely to the first and second directions on the upper surface of the cover plate. A sliding door opening/closing type show case is obtained, which is characterized in that a rail is provided, and wheels that roll along the rail are provided on the lower surface of the sliding door.

Examples will be described below with reference to the drawings.

FIGS. 1 and 2 show an embodiment of a sliding door opening/closing type show case according to the present invention. In FIGS. 1 and 2, this show case includes a container portion 1 having a heat-insulating structure. This container part 1 is constructed by interposing a heat insulating material 4 between an outer box 2 and an inner box 3, and has an article loading/unloading hole 5 at the front part of the upper wall, and an upper end of this article loading/unloading hole 5. That is, a portion normally called an article entry/exit opening is opened and closed by a sliding door 6 that is movable back and forth. sliding door 6
A transparent glass plate is generally used. The front hole wall of the article loading/unloading hole 5 is a transparent window 7 made of a glass plate or the like. Note that the inside of the container section 1 is cooled by a suitable cooling device, and the articles are displayed in a refrigerated or frozen state.

For such a low-temperature show case with a sliding door opening/closing type, two transparent cover plates 8 like sliding doors, which can be opened and closed in the left and right directions, are installed at the lower part of the article loading/unloading hole 5.
8' is provided. For one cover plate 8, the third
As is clear from the figure, a long diagonally extending rail, ie, a convex portion 9, is provided on the upper surface. Further, an arm 12 having a wheel 11 at its tip is provided on the lower surface of the sliding door 6. This wheel 11 includes a sliding door 6, a cover plate 8,
8' are in the position where the article loading/unloading hole 5 is closed, they fit into the frontmost part of the convex part 9,
When the sliding door 6 is moved backward as shown by the arrow, the diagonal convex portion 9 is pressed, and one cover plate 8 is moved in the direction of the arrow 13 by the left-right component of the pressing force. Further, when the sliding door 6 moves forward, the cover plate 8 moves in the opposite direction due to the action of a force in the opposite direction to that described above. Thus, as the sliding door 6 is opened and closed, the cover plate 8 automatically opens and closes the article loading/unloading hole 5.

According to this case, when the sliding door 6 is closed, the cover plate 8 also closes the article loading/unloading hole 5, so there is almost no possibility that the insulation effect of the sliding door 6 and the transparent window 7 will be impaired. When the sliding door 6 is opened, the cover plate 8 also opens and the article loading/unloading hole 5 is opened.
Since the container section 1 is opened, articles can be easily taken in and out of the container section 1.

As explained above using the embodiments, according to the present invention, in addition to the sliding door, there is also a transparent structure at the bottom of the article loading/unloading hole of the container section that automatically opens and closes in a sliding door manner as the sliding door opens and closes. A sliding door opening/closing show case equipped with a cover plate is obtained. According to this show case, there is no inconvenience in putting in and taking out articles, and the display effect is not impaired, and the heat insulation effect can be significantly improved. In addition, since the cover plate is moved in a direction perpendicular to the opening and closing direction of the sliding door, there is no need to provide an area below the opening position of the sliding door to store the cover plate, and therefore the structure is not only simple but also Also, the heat insulating effect is excellent and the double lid can be provided without wasting space inside the refrigerator.

Note that although the above description has been made using a specific embodiment, it goes without saying that various design changes are possible.
