DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-stage open showcase used for displaying frozen or refrigerated foods, fresh foods, etc. in, for example, supermarkets, department stores, convenience stores, etc. The present invention relates to a multi-stage open showcase capable of lighting a display shelf in a well-balanced manner.

[0002]

2. Description of the Related Art An example of this kind of open showcase is disclosed in Japanese Patent No. 2721956,
No. 125993 and Utility Model Registration No. 259015
There is one disclosed in Japanese Unexamined Patent Application Publication No. 2 and the like.

[0003]

In a general multi-stage open showcase, the upper surface of the uppermost display shelf is provided by a fluorescent lamp mounted on the ceiling surface of the inner case, and the upper surface of each intermediate display shelf is provided by a fluorescent lamp. Each of them is illuminated by a fluorescent lamp attached to the tip of the lower surface of the upper display shelf.

However, in the uppermost display shelf, a mirror or a POP rail or the like for attaching a price tag or a name tag of a product is often attached to the back, so that the distance from the ceiling surface of the inner case becomes large. In some cases, the mounting position of the fluorescent lamp must be shifted forward.

[0005] Therefore, if the illumination lamp is fixedly attached to the inner case as in the above-mentioned two conventional examples, the entire uppermost display shelf cannot be illuminated in a well-balanced manner. Display effect is reduced.

The latter conventional showcase has the advantage that the entire interior of the refrigerator can be illuminated in a well-balanced manner because the illuminance of the fluorescent lamp is changed by an inverter ballast. The cost is high.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the lighting fixture can be moved in the front-rear direction so that the entire uppermost display shelf can be illuminated in a well-balanced manner. It aims to provide a multi-stage open showcase.

[0008]

In order to achieve the above object, a multi-stage open showcase of the present invention accommodates a cooler and a blower between an outer case having an open front and an inner case. And a plurality of upper and lower display shelves are provided in a cool box surrounded by the inner case, and cool air blown out from an upper discharge port of the cool air circulation path is drawn into a lower suction port. In a multi-stage open showcase in which an air curtain is formed in the front opening part by keeping the inside of the cool box cool by sucking, a lighting device which turns right and left to illuminate the upper surface of the uppermost display shelf. At least both ends are supported by guide means for guiding the lighting fixture in the front-rear direction along the ceiling surface of the inner case. According to the present invention having the above configuration, the upper surface of the display shelf can be illuminated with good balance by moving the lighting fixture in the front-rear direction according to the front-rear length of the uppermost display shelf or the distance to the ceiling surface.

In the above multi-stage open showcase, it is preferable that a fixing means for preventing the lighting fixture from moving back and forth is provided on the lighting fixture and the inner case ceiling surface or the guide means. With this configuration, the lighting fixture can be fixed at a desired position, so that even if the lighting fixture is inadvertently touched by a hand or the like, the lighting fixture does not shift back and forth.

[0010] In the multi-stage open showcase, the guide means includes a pair of left and right guide rails provided on the inner case ceiling in the front-rear direction, and a lighting fixture holding member slidably supported by the guide rails. It is preferable to be composed of In this case, the lighting fixture can be stably moved in the front-rear direction by simple means.

In the multistage open showcase, it is preferable that the guide rail is buried in the ceiling of the inner case such that the lower surface thereof is substantially flush with the ceiling surface of the inner case. In this case, the appearance is improved because the guide rail is not exposed.

In the above-mentioned multi-stage open showcase, the fixing means is made of a magnet mounted on the upper part of the lighting fixture so as to be separated from the ceiling surface of the inner case or the lower surface of the guide rail, and the lighting fixture is lifted upward. At this time, it is preferable that the magnet be attracted to the ceiling surface of the inner case or the lower surface of the guide rail formed of a magnetic material to prevent the lighting fixture from moving back and forth. With this configuration, the lighting fixture can be easily fixed and released.

In the above-mentioned multi-stage type open showcase, the luminaire is provided inside a reflector having a lower end opening supported by the guide means so as to be slidable back and forth, and a magnet is mounted on the upper surface of the reflector. preferable. By doing so, the illuminance of the lighting fixture is increased, so that the upper surface of the uppermost display shelf can be more effectively illuminated.

In the above-mentioned multi-stage open showcase, it is preferable that the reflector is attached to the guide means so as to be rotatable in the front-rear direction. In this way, by changing the irradiation direction of the lighting fixture, it is possible to illuminate the upper surface of the display shelf in a balanced manner while minimizing the movement in the front-back direction.
