Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an open showcase installed in a convenience store and the like, and more particularly, to a mounting structure for the lighting plate.
[0002]
[Prior art]
The above-mentioned lighting plate is attached to the upper front part of the showcase body and is used for displaying and explaining displayed products. Conventionally, this lighting plate is fastened and fixed to the showcase body with screws.
[0003]
[Problems to be solved by the invention]
Therefore, if the lighting plate becomes dirty or cracked and needs to be replaced, a driver must be used, and the replacement work is very troublesome. An object of the present invention is to facilitate replacement of the lighting plate and to prevent it from falling off.
[0004]
[Means for Solving the Problems]
According to the present invention, a gap for inserting the upper end of the lighting plate is formed in the showcase body, and a pair of left and right hooks are provided on the back of the lighting plate, and the upper end is inserted into the gap. Both ends of the sight plate are supported and held by a hook metal fitting. According to such a means, the lighting plate can be attached and detached only by inserting and hooking without using a screw.
[0005]
The gap into which the upper end of the lighting plate is inserted is formed between the canopy front panel that covers the upper edge of the front of the showcase body and the light rail that supports the fluorescent lamp behind the lighting plate. It is preferable to fix the light rail to the light rail, so that the present invention can be easily applied without making a significant design change to the showcase body. Furthermore, if a molding having an S-shaped cross section is fitted and fixed to the lower end portion of the lighting plate, and the lighting plate is supported by the hanging metal fitting through this molding, the molding that protects the lower end surface of the lighting plate. Can be used also as a hook for engaging with the hook metal fitting.
[0006]
Furthermore, if the decorative screw is screwed in from the back of the hook to the upper side of the molding and the molding screw is pressed against the molding to prevent the lighting plate from being lifted, the lighting plate can be held more securely. In addition, the danger that the lighting plate is detached from the hook metal fitting due to vibration during transportation or some external force during use can be eliminated.

DETAILED DESCRIPTION OF THE INVENTION
The embodiment of the present invention will be described below with reference to FIGS. First, FIG. 3 is a schematic longitudinal sectional view showing the entire configuration of the open showcase. In FIG. 3, the open showcase has two layers of cool air circulation passages 2 and 3 inside and outside the main body 1 formed of a heat insulating wall, and the cool air circulating through a cooler (not shown) by a fan (not shown) is indicated by arrows. Are blown out from the outlets 4 and 5, and an air curtain is formed on the front surface to cool the interior. In the warehouse, shelves 6 are installed in multiple stages, and products 7 are refrigerated and displayed, and are illuminated by interior lighting (fluorescent lamps) 8. A square-band electric lighting plate 9 made of, for example, a translucent acrylic resin plate is attached to the front upper portion of the showcase main body 1, and a canopy illumination (fluorescent lamp) 10 is installed behind it. On the front surface of the lighting board 9, the type, features, price, etc. of the displayed product are displayed, for example, with a sticker. The canopy illumination 10 illuminates the electric lighting plate 9 from the back side, and illuminates the front and feet of the open showcase.
[0008]
FIG. 1 is an enlarged view of a portion A in FIG. 3, and FIG. 2 is an exploded perspective view of the lighting plate and the hook metal fitting in FIG. In Fig. 1, the front upper edge of the showcase body 1 is mounted by the canopy front panel 11 screw 12 covering this portion. The canopy front panel 11 is a long decorative frame that extends across the width of the showcase body 1, is bent from an iron plate into a J-shaped cross section in the figure, and is fixed so as to cover the upper surface of the showcase body 1 in the illustrated position. A light rail 13 that supports the canopy illumination 10 is provided inside the canopy front panel 11.
[0009]
The light rail 13 is also a horizontally long material formed by bending from an iron plate into a cross-section in the figure, and is fixed to the slopes of the two trapezoidal support brackets 14 by screws 15. It is fixed to the showcase body 1. A fluorescent lamp holder 17 made of a resin molded product is fixed to the front surface of the light rail 13 by fitting into two left and right portions, and the canopy illumination 10 is held and fixed by the fluorescent lamp holder 17. A lighting circuit and wiring for the canopy illumination 10 are housed behind the light rail 13. Here, vertical rising pieces 11a and 13a are provided at the opposing portions of the canopy front panel 11 and the light rail 13, respectively, and a gap G slightly larger than the thickness of the lighting plate 9 is formed between them. Has been.
[0010]
On the other hand, in FIG. 1 and FIG. 2, a pair of left and right hooking metal fittings 18 are attached to the front surface of the light rail 13 by tightening with screws 15. The hook 18 is made of an iron plate, and as shown in FIG. 2, a mounting portion 18a parallel to the light rail 13 is bent at the upper end, and a receiving portion 18b for supporting the lighting plate 9 is bent at the lower end. Further, a reinforcing side piece 18c is bent on one side surface. A screw hole is provided in the vicinity of the receiving portion 18b, and a decorative screw 19 is screwed into the screw hole. A molding 20 is fixed to the lower end portion of the lighting plate 9. The molding 20 is extruded from aluminum with an S-shaped cross section, and is fitted into the lighting plate 9 through an upward recess, and is joined with an adhesive or double-sided adhesive tape to protect the lower end surface of the lighting plate 9. doing. The other downward concave portion of the molding 20 serves as a hook that engages with the receiving portion 13 b of the hook metal fitting 18.
[0011]
In the configuration described above, in order to attach the lighting plate 9 to the state of FIG. 1, the decorative screw 19 is moved backward, the upper end of the lighting plate 9 is inserted into the gap G from below, and then the lower end via the molding 20. The part is supported by the hook metal fitting 18. Thereafter, when the decorative screw 19 is advanced, the screw shaft portion protrudes close to the upper surface of the molding 20 and presses the lighting plate 9 so as not to lift. In order to remove the lighting plate 9, the decorative screw 19 is retracted, the lighting plate 9 is lifted, the molding 20 is pulled out from the hook 18, and then the lighting plate 9 is pulled down.
[0012]
According to the illustrated embodiment, it is possible to attach and detach the lighting plate 9 only by inserting it into the gap G and hooking it on the hook metal fitting 18. Further, by pressing the molding 20 with the decorative screw 19, there is no fear that the lighting plate 9 will come off due to vibrations during transportation or contact with a hand when replenishing goods. Further, the gap G is formed by using the canopy front panel 11 and the light rail 13, and the hooking metal fitting 18 is fixed by using the light rail 13, so that the design of the open showcase is not significantly changed. Can be implemented. However, the present invention is not limited to the illustrated embodiment, and even if the front upper portion of the showcase body to which the lighting plate 9 is attached has a different structure, by adding an appropriate auxiliary member Arbitrarily applicable.
[0013]
【The invention's effect】
As described above, according to the present invention, the replacement of the lighting plate can be easily performed without using a tool such as a driver, but there is no fear of coming off due to vibration during transportation or unexpected external force. Serviceability is greatly improved.
