Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a lighting device for an assembly type display shelf in which products and the like are placed and displayed on the shelf.

[Prior Art] For example, in stores such as supermarkets, display shelves are often used that have multiple shelves arranged above and below for displaying products. In this type of display shelf, lighting equipment is often installed above the products in order to illuminate the products on the shelf and clearly indicate the contents.

Conventionally, when a lighting fixture is attached to a display shelf, the lighting fixture is usually prepared as a separate unit and is mounted on the upper frame of the display shelf body.

[Problems that the invention aims to solve] However, with such existing mounting structures, not only is it time-consuming to install lighting equipment and power distribution work, but also
This can lead to problems where the power supply wiring for lighting equipment and the ballasts required for discharge lamps are exposed around the display shelves and on the floor. That is, if wiring or ballasts are exposed,
Wires may be accidentally caught, the ballast may become an obstruction in the arrangement of display shelves, or otherwise it may become unsightly.

The present invention can solve the above-mentioned inconveniences without complicating the on-site assembly of display shelves, and also makes it easier to inspect and replace the ballast. The purpose is to provide lighting devices for display shelves.

[Means for Solving the Problems] The present invention takes the following measures to achieve the above objectives. That is, the lighting device for a display shelf according to the present invention is applied to an assembly-type display shelf in which a lighting fixture is mounted on an upper frame that is removably installed between columns, The frame is made into a channel-shaped frame that opens downward, and the main body of the lighting fixture is attached to this upper frame via a support leg pipe, and power supply wiring is built into the upper frame and the support leg pipe, and the upper frame is connected to the upper frame. It is characterized by a stabilizer installed inside the frame.

[Function] With such a configuration, it is possible to prevent the power supply wiring and the ballast from being exposed to the outside. In addition, the upper frame, the lighting fixture body, the support leg pipe, the power supply wiring, and the ballast are assembled together at the factory, and this integrated structure is transported to the site and used as a component of the display shelf. Can be assembled between pillars. Therefore, the problem of complicating the assembly work of display shelves due to the presence of lighting equipment is eliminated. Moreover, since the upper frame has a channel shape that opens downward, the ballast can be easily removed from the bottom even when the upper frame is assembled between the supports. be. Ballasts are devices that tend to need to be replaced due to failure or lifespan, although not as frequently as discharge lamps, so it is important to be able to replace ballasts without disassembling display shelves. Useful.

[Example] The present invention will be described in detail below with reference to an example shown in the drawings.

First, the overall structure of the display shelf will be described with reference to FIGS. 2 to 4.

A display shelf, exemplified by a bread shelf, is made up of assembled units A and B connected together, and each unit has a common configuration. The display shelf body 1 is constructed by connecting columns 2, 2 erected on both sides thereof and upper and lower frames 3, 4 which are horizontally suspended between the columns. These pillars 2, 2 and the upper and lower frames 3, 4 are both formed from hollow channel material. That is, as shown in FIG. 4, the upper frame 3 has a downwardly opened channel shape, which is formed by opening the central portion of the bottom wall 3c in the longitudinal direction. The central pillar 2 is shared by units A and B on both sides.

FIG. 4 illustrates the connection structure of the upper frame 3 to the support column 2. Hook-shaped claw pieces 3a, 3a are protruded from both ends of the upper frame 3, while the support column 2
Slit-like hooking holes 2a, 2a are opened in the inner surface of the holder, and the claw pieces 3a of the upper frame 3 are fitted into the hooking holes 2a of the support column 2 as shown by the arrows in the figure, so that the two are engaged. ing. A notch hole 5 is cut in the upper end side surface of the support column 2 to which the upper frame 3 is connected, through which power supply wiring, which will be described later, is passed. In addition, pillar 2
There are a pair of slit-shaped hook holes 2 on the front of the
b and 2b are arranged in a row.

On the front surface of the display shelf body 1, a stock case 6 is fixed at the lower part, and three upper and lower glass shelf plates 7a, 7b, and 7c are protruded from the upper part.

The stock case 6 consists of a hollow box body having a storage space inside, and the inner surface of the support column 2 is fixed in close contact with the rear side of the side plate 6b.
Further, each side end of the front plates 6a, 6a of the stock case 6 is hinged to the case side plate 6b to form an opening/closing door that can be opened from both sides. In addition, stock case 6
There are a pair of casters 8, 8 on the bottom of both sides for movement.
is installed.

On the other hand, as shown in FIG. 3, the shelf boards 7a, 7b, and 7c are supported by brackets 9 that are respectively engaged with the front hooking holes 2b of the support columns 2, and are normally held in a horizontal position. A front fall stopper 10a and a side fall stopper 1 are formed with wire rods around the top surface of each shelf board and the top surface of the stock case 6.
0b and a rear fall prevention device 10c are attached, and target products (bread, etc.) are displayed on top of these.

Next, the lighting equipment installed on the display shelf body 1 will be explained. The lighting equipment includes a main body 11 in which a discharge lamp (fluorescent lamp) 11a is supported by terminals 11b on both sides, and an L-shaped side surface for supporting and fixing the main body 11 by horizontally suspending it directly above a display shelf. It consists of a pair of supporting leg pipes 12, 12. Each supporting leg pipe 12 has its lower end 12a inserted into a through hole 13 opened at the mounting position of the upper surface 3b of the upper frame 3, and is screwed into a fixing nut 14 from the inner side, so that it can be attached to and detached from the upper frame 3. Installed.

In addition, in Fig. 1, 15 is the supporting leg pipe 1.
2 and 12, a display plate is shown suspended from a horizontal pipe 16 installed at 2 and 12.

Thus, the power supply circuit necessary for the lighting fixture (discharge lamp 11a) set on the upper frame 3 is constructed as follows. Inside the upper frame 3, as shown in FIG. 1, an electronic ballast 17, which is indispensable for the operation of the discharge lamp 11a, is installed in advance at an appropriate position on the bottom plate 3c, and a power supply wiring 18a is installed in the upper frame 3. ,1
It is built in together with 8b. This built-in ballast 17 is used to configure a power supply circuit for the discharge lamp 11a.

Specifically, it is as follows. First, in the case of unit A, a power supply cord 18 is already installed inside the support column 2 on one side thereof. This power supply cord 18 is extended to the outside from an opening at the lower end of the column, and a terminal plug 19 is inserted into an external outlet (not shown). Further, a power supply cord 18 extending upward within the support column 2 is introduced into the upper frame 3 through the cutout hole 5. Then, the power supply wiring 18a of the power supply cord 18 conducted inside the upper frame 3,
18b connects one side of the supporting leg pipe 12 to the terminal 11b of the discharge lamp 11a through the inside;
The other end is also connected to the terminal 11b from the supporting leg pipe 12 on the opposite side via the built-in ballast 17, thereby configuring a necessary power supply circuit. Further, the power supply wirings 18a, 18b branch out another power supply circuit 18c, 18d in parallel at the upper frame 3, and a terminal female plug 20a is arranged near the end on the opposite side to the introduction side.

In addition, for unit B, the necessary ballast is built into the upper frame 3 along with the power supply wiring 18a and 18b, as in unit A, and the power supply circuit for the lighting equipment above it can be constructed in the same way. . However, in this case, the terminal male plug 20b is stored and ready near the column, and it is pulled out to the unit A side through the notched holes 5, 5 on both sides of the column 2, and connected to the power supply easily by inserting it into the female plug 20a. We have devised a way to make it possible. When three or more units are placed adjacent to each other, the same connection work is sequentially performed.

If the display shelf is equipped with the above-mentioned lighting device, when installing the lighting equipment on the upper frame 3, it is necessary to connect the power supply wirings 18a and 18b connected to the ballast 17 built into the upper frame 3. Pull it out and pass it through the supporting leg pipes 12, 12 to attach the discharge lamp 11a.
By simply connecting the terminals 11b and 11b on both sides, a power supply circuit can be easily constructed. and,
In this power supply circuit connection state, one side support 2
Except for the power supply cord 18 extending from the lower end, the bulky ballast 17 and power supply wiring 18a, 18b are completely housed inside the upper frame 3, etc., eliminating the problem of them being exposed to the outside. In other words, there is no chance of wires getting caught, ballasts etc. getting in the way, or spoiling the appearance. In addition, if it has such a configuration, the upper frame 3, the lighting fixture main body 11, the supporting leg pipe 12, the power supply wiring 18a,
18b, 18c, 18d and the stabilizer 17 are assembled integrally at the factory, and this integrated structure is transported to the site and used as a component of the display shelf for the supports 2, 2.
It is also possible to assemble it between the two. Therefore, the problem of complicating the assembly work of display shelves due to the presence of lighting equipment is eliminated. Moreover, since the upper frame 3 has a channel shape that opens downward, the stabilizer 17 can be removed from the bottom even when the upper frame 3 is assembled between the supports 2, 2. It is easy to do. That is, the stabilizer 17 is set to a size that allows it to pass through the opening formed in the bottom plate 3c of the upper frame, and the stabilizer 17 is
If the stabilizer 7 is moved forward or backward and screwed to the bottom wall 3c, the stabilizer 17 can be easily removed.

In particular, with the unit connection type of the embodiment, the second and subsequent units do not require a dedicated power supply, and can be connected to the power supply by connecting the plugs 20a and 20b, which doubles the convenience. become what is done.

Note that the format of the lighting fixture body set on the upper frame of the display shelf, the configuration of the power supply circuit, etc. are not limited to the illustrated embodiments.

[Effects of the invention] Since the present invention has the above-described configuration, it is possible to not only effectively prevent the power supply wiring and the ballast from being exposed to the outside, but also to prevent the wiring and the ballast from being exposed to the upper frame and The lighting equipment can be assembled as an integrated structure in a factory or the like, and the integrated structure can be handled on-site as a component of a display shelf. Therefore, there is no problem that the assembly of the display shelf becomes complicated due to the presence of the lighting equipment, and the assembly work can be simplified. In particular, the power supply wiring and ballast can be preassembled and integrated in a factory, etc., so on-site wiring work can be omitted, and there is no need for special technicians for electrical wiring. It becomes possible to assemble display shelves. Moreover, since the upper frame is made into a channel-like structure that opens downward and the stabilizer is housed within the upper frame, the stabilizer can be easily removed without disassembling the display shelf. become. Therefore, although the ballast is not exposed to the outside, maintenance, inspection, and replacement work can be performed easily.
