DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention displays a product inside and illuminates the inside of a case having an open front from a diagonally forward direction.
The present invention relates to an illumination light cover support structure for a showcase that supports a cover for covering the front and upper surfaces of the illumination lamp supported on the front upper edge of the front opening from the front side and the upper side of the illumination lamp.

[0002]

2. Description of the Related Art A showcase with a case in which products are displayed and the front surface is opened inside is premised on that customers select products displayed in the case while looking at them and take out and purchase the products themselves. It is a self-service device.
Therefore, the front of the case has a large opening so that customers can easily see and take out the products displayed in the case. The front opening of the case does not contaminate the displayed products with dust or outside air invading from the outside, or the temperature of the products displayed and displayed in the case in a state of being kept cool or warm does not rise or fall. Thus, it is generally covered with a transparent door or an air curtain that blocks the inside and outside of the case. In order to make it easier for customers to view the products displayed in the case, there are many showcases in which an illumination lamp for illuminating the inside of the case from the upper front is provided in front of the opening of the case. The illumination lamp of such a showcase has a rear end supported at an upper part of a front end of the case, and is supported by a support body extending left and right along the upper part of the front end and a front end protruding forward. On the upper surface of the support, lighting circuit components for lighting lamps and the like are generally supported. Through the support that supports the lighting circuit components and the like for lighting lamps on the upper surface, the lighting lamp is moved to the front and upper surfaces thereof. Is usually covered with a cover screwed and supported by a case from the front side and the top side of the lamp. When performing maintenance work such as inspection, repair, and cleaning of lighting circuit components for lightings, it is necessary to remove the screwed cover, and such a cover requires time and effort. One conventional showcase illuminating lamp cover support structure is shown in FIGS. FIG. 4 is a left vertical sectional view showing a configuration of a front open type showcase to which the present invention is applied, and FIG. In each case, the right side of the figure is the front side.

In FIGS. 4 and 5, reference numeral 1 denotes a case. The case 1 has a case main body 2 formed of a heat-insulating wall and having a C-shaped side vertical cross section that is open at both left and right side surfaces and a front surface.
A partition 3 is provided along the inner peripheral surface of the case body 2 and supported at intervals, and side plates 4 are provided to cover the left and right sides of the case body 2 and the partition 3, and are open to the front. An opening 5 is formed. On the front surface of the upper end of the front end of the case body 2 forming the upper edge of the opening 5, an inverted U-shaped support member 6 extending right and left along the front surface and having a flat side longitudinal section is cantilevered at the rear end. Have been. On the lower surface of the support 6, an illuminating lamp 7, which is a fluorescent lamp for illuminating the inside of the case 1 from above, is suspended and supported. Components such as lighting circuit components for the lamp 7 such as tubes are supported. The illuminating lamp 7 has a front surface and an upper surface which are covered by a cover 9 having a vertical vertical cross section in the shape of a letter F from the front side and the upper surface. Put this cover 9 in case 1
The support structure for the lighting cover of the showcase,
Screw the rear end of the cover 9 to the front end of the upper surface of the case body 2
It is structured to support with screws.

A space in the case 1 surrounded by the case body 2, the partition wall 3 and the side plate 4 forms a ventilation passage 11, and upper and lower edges of an opening 5 at both upper and lower ends of the ventilation passage 11. The openings 12 and the openings facing each other vertically form the outlet 12 and the inlet 13, respectively. The upward opening face of the suction port 13 is a suction port cover 14 in which a large number of ventilation holes (not shown) are formed on the left and right, and the downward opening face of the air outlet 12 is a honeycomb-shaped rectifying body 15 having open upper and lower ends. Each is covered with. In addition, a plurality of display shelves 16 for displaying and displaying products are vertically arranged in the case 1 and the rear end is cantilevered on the vertical wall surface of the partition wall 3.
An evaporator 17, a blower 18, and the like, which are components of the refrigerator, are provided. The air sucked into the air passage 11 from the air inlet 13 through the vent hole (not shown) by the blower 18 is cooled by the evaporator 17 to become cool air, is rectified through the rectifier 15 and becomes laminar flow, and the air outlet. Speech from 12,
An air curtain 19 that covers the opening 5 is formed to keep the inside of the case 1 cool, and to cool the products displayed on the display shelf 16 in the case 1, to be sucked in again from the suction port 13, and to cool the inside of the case 1. A circulating circulation stream 20 is formed.

[0005]

In such a conventional illumination light cover support structure for a showcase, the rear end of the cover 9 is screwed to the front end of the upper surface of the case body 2 with screws 10. Therefore, when performing maintenance work such as checking, repairing, cleaning, and the like, parts such as a ballast 8 and a lighting circuit part for the lighting lamp 7 such as a lighting tube (not shown) supported on the upper surface of the support 6, After removing the cover 9 and performing inspection, repair, cleaning, etc., it is necessary to screw it to the case main body 2 with screws 10 and attach the cover 9 to the case 1 again. There is a problem that becomes. In addition, cover 9 is attached to case 1
However, if the cover 9 can be easily detached or opened and closed simply by being detachably or freely opened and closed, there is a problem that the cover 9 is easily removed or opened by mischief.

According to the present invention, it is possible to quickly and easily perform maintenance work such as inspection, repair, and cleaning of components such as lighting circuit components for an illumination lamp, which are covered by a cover and supported on an upper surface of a support, and An object of the present invention is to provide a support structure for a lighting cover of a showcase in which a cover is not removed or opened without permission.

[0007]
