Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention The present invention relates to a showcase provided with a lighting device for interior lighting.

2. Description of the Related Art In a conventional showcase, in order to make it easier to clearly and externally confirm the items stored in the storage room, it is common to illuminate the storage room with a lighting device. One example is disclosed in Japanese Patent Publication No. 19669. In this publication, fluorescent lamps are installed in the vertical direction on the inside surfaces of the left and right side walls formed of heat insulating walls. Further, Japanese Utility Model Publication No. 60-9671 discloses a showcase in which a space is formed at the front end of a heat insulating wall and an illumination lamp is arranged in this space.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the former publication of the above-mentioned technique, since the fluorescent lamp itself is mounted on the inner surface of the left and right side walls, it is used for taking in and out the product by protruding from the left and right side walls to the inside It is undeniable that the opening will be narrowed. In addition, the electrical components for supplying power to this fluorescent lamp are usually arranged in the machine room, which is usually partitioned by a heat insulating wall below the storage room, to illuminate the inside of the storage (upper or front of the storage). In order to guide the wiring of the lighting device to the machine room, it is necessary to pass through the space on the back wall side or columns and form holes or notches in the edges of the bottom wall of the heat insulating wall. However, there is a problem that the wiring work is very troublesome and the wiring distance becomes long. On the other hand, in the latter publication, since the side plate is formed of a heat insulating wall, there is no problem because the thickness can be made thicker than the thickness of the illumination lamp, but in a low temperature showcase where a transparent plate is arranged on the side surface of the storage. On the other hand, since the transparent plate is thinner than the thickness of the lighting, it cannot be applied as it is.Since the transparent plate is usually installed at the installation site, the lighting device will also be installed together. It has been desired that the mounting operation of the lighting device can be simplified as much as possible.

Therefore, the present invention provides a showcase on the premise that transparent plates are provided on both the left and right side surfaces, so that the work of attaching and detaching the lighting device can be easily performed.

[Structure of Invention]

Means for Solving the Problems The present invention provides a showcase including a heat insulating wall in which transparent plates through which the inside of a storage chamber can be seen can be seen. The groove part receives a front end of the transparent plate. Formed on either one of the groove portion or the folded portion, and a front frame provided with a storage portion that is continuous with the outer wall of the groove portion, extends forward, has a folded portion at the front portion, and forms a space between the folded portion and the groove portion. A cover made of a light-transmissive material, one end of which is locked to the locking piece and the other end of which is fixed to the other by a fixing tool and which forms a cavity for housing the lighting device together with the housing. is there.

The space that is formed in front of the groove is formed by the storage section that is connected to the groove that inserts the front end of the transparent plate.Therefore, use this space as the wiring space for the lighting device and fix the cover to the front frame to form a cover. A cavity is formed with the storage portion, and this cavity is used as an installation space for the lighting device. Therefore, in addition to covering and fixing the front end of the transparent plate with the front frame, the lighting device and the cover are fixed. Further, since the front frame and the cover form a cavity in front of the transparent plate, when the impact from the front is applied to the showcase, the cavity acts so as to mitigate the impact. Also, the transparent plate can be protected.
