Description

[Detailed explanation of the invention] (a) Industrial application field This invention provides a storage chamber on the front part of the upper wall of the case body with a front opening to store a plurality of fluorescent lamp ballasts for illuminating the inside of the case body. Regarding the case.

(b) Prior Art A structure in which a storage chamber is created using a canopy cover that covers the front end of the upper wall of a front-opening show case body and a stabilizer is attached to the inner surface of the cover is disclosed in Utility Model Publication No. 59-13889. According to this idea, work on the storage chamber is done by opening the closing plate that closes off the bottom surface of the storage chamber, and it is also quite difficult to install the ballast and perform wiring.

Further, a configuration in which a plurality of stabilizers are attached to a mounting plate is disclosed in Utility Model Publication No. 55-29416. In this case, the ballast is screwed to a mounting plate, and the mounting plate is screwed to a recessed portion at the lower front of the case body, making the installation and wiring work difficult.

(c) Problems to be solved by the invention The conventional technology described above has difficulty in workability, does not have a configuration that allows easy installation of the ballast, and is not suitable for inspection or repair.

The present invention provides a storage chamber for the ballast at the front end of the upper surface of the case body, and when the ballasts are installed side by side in this storage chamber, it is easy to attach and remove the ballasts individually, and it is possible to easily install and remove the ballasts individually. To provide a structure in which the electrical wiring can be easily installed and removed all at once, the electrical wiring can be short, and the wiring work can be easily performed.

(d) Measures to solve the problem The storage case provided on the front part of the upper wall of the case body includes a locking tool that forms a locking groove that opens forward between the upper surface of the upper wall and the storage case. , a stabilizer mounting plate is provided, the rear end of which is inserted and locked in the locking groove, and the front end is fixed to the front part of the upper wall with a fixing device; a locking piece that locks when inserted from the ballast, and a front end of the stabilizer mounting plate has an extension extending forward from the front end surface of the upper wall;
This extension part is provided with a fitting hole for a fixture for fixing the front part of the stabilizer, and the front part of the stabilizer mounting plate is fixed to the front part of the upper wall.

(E) Function Multiple ballasts can be placed on the ballast mounting plate at predetermined intervals, and the ballast mounting plate with the ballasts installed in the storage chamber is inserted into the locking groove at the rear end and the front end is placed at the top. Fix it to the front of the wall. In addition, even if the fixing tool at the front of the ballast passes through the ballast mounting plate, the extension part will not hit the front end surface of the upper wall, so the top surface of the ballast mounting plate can remain flat, and multiple Ballasts can be installed and removed all at once, and ballasts can also be removed individually.

(F) Example 1 is a case with an opening at the front, and a partition plate 3 is provided inside the case body 2 which is made up of a heat insulating wall, and a cooler and a blower are housed between the case body 2 and the partition plate 3. A cold air passage 4 is formed, and a plurality of food storage shelves 5 are arranged in front of the partition plate 3 as a food storage room. The cold air in the cold air passage 4 is supplied by a blower from the air outlet 6 at the upper end of the front opening to the suction port 7 at the lower end.
The inside of the storage room is kept within a predetermined temperature range. Side plates are attached to the left and right side surfaces of the show case 1, but when two or more show cases 1 are connected laterally, the side plates are omitted from the connected sides, and the show cases 1 are directly connected to each other. Reference numeral 8 denotes a storage chamber extending to the left and right ends of the case body 2 on the front part of the upper wall 9 of the case body 2. The cover 10 forming the upper surface can be opened and closed upward at the front and rear parts by hinges 11 and 12. . 13 is the upper wall 9
This is a support member that is attached to the cover 10 and serves as a contact plate when the cover 10 is closed. Reference numeral 14 supports a reflecting plate 15 with two left and right supporting members fixed to the supporting member and the upper wall 9, and a fluorescent lamp 16 for illuminating the storage room is arranged on the lower surface of the reflecting plate 15. Inside the storage room there are fluorescent lights 17 and each shelf 5.
It is illuminated by a fluorescent light installed on the lower surface of the front end. 1
Reference numeral 9 denotes a ballast for each of the above-mentioned fluorescent lamps, which is laterally supported by a ballast mounting plate 20 at a predetermined interval. 21
A locking portion at the rear end of the stabilizer mounting plate 20 is inserted and supported by a locking piece that forms a locking groove in a triangular shape or the like that opens forward with the upper surface of the upper wall 9 in the storage chamber 8. perform an action. The ballast mounting plate 20 extends horizontally into the storage chamber 8, and has a substantially hook-shaped ballast locking portion 22 at the rear of the top surface that opens forward so that a plurality of ballasts 19 can be mounted side by side in the storage chamber 8. A locking piece 23 is provided for each ballast 19 by cutting and raising the mounting plate 20, or is provided horizontally long in common to each ballast, and the mounting plate 20 further has a front end of the upper surface attached to the upper wall 9. An extension part 24 extending forward from the front end surface is formed, and a fixing hole 25 for each stabilizer 19 is provided corresponding to the extension part 24. At the bottom, it is fixed to the front end surface of the upper wall 9 with a fixing device such as a screw. To attach the stabilizer 19, the rear end is inserted into the lower surface of the locking piece 23, and the front end is fixed with a fixing device 26 such as a screw. After installing each ballast 19, move the ballast mounting plate 20 to the storage chamber 8.
The rear end of the mounting plate 20 is inserted into the lower surface of the locking piece 21 to be supported, and the front end is fixed to the front end of the upper wall 9 with a fixture 27. In this case, the fixture 26 is attached to the mounting plate 2.
Even if the fixing tool 26 passes through the mounting plate 20, it does not touch the upper wall 9 because it is inside the extension part 24.
can be held in close contact with the upper surface of the upper wall 9. Reference numeral 28 denotes a decorative plate that covers the front of the storage chamber 8 and the front of the fluorescent lamp 16, and its upper end can be attached to and detached from the support member 13 with screws.

When inspecting or repairing, opening the cover 10 opens the top surface of the storage chamber 8, making the work easy. Furthermore, since the storage chamber 8 is located at the top, the work is easier than when it is located at the bottom.

FIG. 5 shows another embodiment in which the locking member 21 forms a substantially U-shaped groove and the extending portion 24
is bent into a substantially inverted U-shape, and the stabilizer mounting plate 20 is fixed to the upper wall 9 by fixing its front end to the upper surface of the upper wall 9 using a fixture 27.

(g) Effects of the invention In this invention, multiple ballasts are arranged on the mounting plate, so there is no need to unnecessarily lengthen the wiring, and the wiring work is easier. The mounting on the upper wall of the mounting plate is easy as the rear end is locked to the locking piece and the front end is fixed with the fixing tool. Because of the presence of the extending part, the mounting plate does not hit the top wall, so there is no need to make a missing part for the fixing device on the top wall, and the mounting plate, which has an increased load when each ballast is attached, can be slid onto the top of the top wall. It can be stably placed in a predetermined position. Furthermore, when making repairs or inspections, by pulling the mounting plate forward, each ballast can be pulled forward at once, improving work efficiency.
