2. Description of the Related Art Conventionally, in an exhibition device such as an open showcase, as shown in, for example, Japanese Utility Model Publication No. 61-35102 (A47F11 / 00), a plurality of shelves are installed in the exhibition room and A fluorescent lamp for illumination and a glow starter socket for connecting the glow starter of this fluorescent lamp are attached to the lower surface.

The conventional display device and glow starter socket shown in FIGS. 5 to 8 will be described below.
An open showcase S partially shown in FIG. 8 is a low temperature showcase for cooling products such as foods for display and sale in a low temperature state, and a partition arranged with a space 2 in the heat insulating box 1. An exhibition room D opened to the front is formed in the plate 3. Cold air from a refrigerating device (not shown) is blown into the exhibition room D through the interval 2 and the interior of the exhibition room D is cooled to a predetermined refrigerating temperature.

In the exhibition room D, a plurality of shelves 4 are installed. The shelf 4 has its rear end supported by a column (not shown) of the partition plate 3, and further, as shown in FIG.
The mounting angle with respect to is variable. That is, in FIG. 8, the lower shelf 4 is horizontally installed, but the upper shelf 4 is installed.
The front side is erected so that it is rotated around the rear side as the center of rotation so that the food and the like displayed on the upper surface can be easily seen by the customer.

A shelf reinforcing plate 6 having a substantially V-shaped cross section is attached to the front part of the lower surface of each shelf 4 and a fluorescent lamp 7 is attached to the front of the shelf reinforcing plate 6 across the left and right. ing. On the other hand, a conventional glow starter socket 100 for connecting and attaching the glow starter 8 of the fluorescent lamp 7 is attached to the rear surface of the shelf reinforcing plate 6. As shown in FIG. 5, a conventional glow starter socket 100 is composed of a rectangular flat plate-shaped main body 101 made of hard synthetic resin and a socket cover 102 that is erected on the upper surface of the main body 101 by integral molding. An insertion opening 103 of the glow starter 8 is opened at the upper end of the above, and a receiving metal fitting (not shown) for receiving the glow starter 8 is attached to the bottom surface thereof. Lead wires 106, 106 to fluorescent lamp sockets 104, 104 to which both ends of the fluorescent lamp 7 are connected are drawn from one side surface of the main body 101, and lead wires to a power plug 107 are drawn from the other side surface. The line 108 is drawn out.

As shown in FIG. 7, the glow starter socket 100 is attached to the shelf reinforcing plate 6 by screws with the bottom surface of the main body 101 abutting against the rear surface of the shelf reinforcing plate 6. Therefore, the glow starter socket 100
Since the shelf 4 is in a horizontal state and the insertion port 103 is inclined downward, moisture such as dew condensation water does not flow into the glow starter socket 100 from the insertion port 103.
As a result, it is possible to prevent the occurrence of electric leakage and short-circuit failure.

[0007]

However, according to such a conventional structure, since the glow starter socket 100 projects and projects below the shelf 4 when the shelf 4 is horizontally installed as shown in the lower part of FIG. However, there is a problem that the hand of the customer or the product is apt to collide with the glow starter 8 when the product is taken in and out, and thereby the glow starter 8 comes off from the glow starter socket 100 and falls.

Further, when the shelf 4 is installed so as to be inclined as shown in the upper part of FIG. 8, the opening direction of the insertion opening 103 of the glow starter socket 100 is directed upward as the inclination angle becomes steeper, and the shelf 4 There is also a problem that water such as dew condensation water that flows down along the lower surface flows into the glow starter socket 100 from the insertion port 103 to cause electric leakage or a short-circuit failure.

Further, since the lead wires 106, 106, 108 of the glow starter socket 100 are molded integrally with the main body 101 when the glow starter socket 100 is molded, the lead wires 106, 106, 108 are heated by the heat at that time.
The portions of 106 and 108 pulled out from the main body 101 have lower strength and flexibility than the other portions. Further, in the conventional glow starter socket 100, as shown in FIG. 6, the lead wires 106 and 106 are attached to the front end side of the shelf 4, and the lead wire 108 is attached to the rear end side thereof.
6 is bent immediately after being pulled out from the main body 101 as shown in FIG. 6, and has a shape straddling the apex of the shelf reinforcing plate 6 as shown in FIG. Therefore, since the weakest portions of the lead wires 106 and 106 are bent, cracks are likely to occur due to contact with a product or the like, and there is also a problem that leakage current also occurs from the lead wires 106.

The present invention has been made to solve the above-mentioned conventional technical problems, and an object of the present invention is to prevent the glow starter from coming off from a glow starter socket attached to an exhibition apparatus.

Another object of the present invention is to provide a display device capable of preventing moisture from entering the glow starter socket even if the mounting angle of the shelf is changed.

The one-touch clip 22 is positioned on the insertion opening 12 side of the rib 21 with a predetermined interval, and the line connecting the rib 21 and the one-touch clip 22 shown by a two-dot chain line in FIG.
They are arranged side by side with a slight allowance to the opening direction so as to intersect with the opening direction of 2 (shown by a chain line) at an acute angle.
That is, with the insertion opening 12 facing right as shown in FIG.
1 is configured to be slightly smaller than the one-touch clip 22.

On the other hand, although not shown, two engaging holes, which are not shown, are provided on the rear surface of the shelf reinforcing plate 6 of the shelf 4, and
Moreover, they are arranged side by side so as to have the same height in the longitudinal direction (lateral direction) of the reinforcing plate 6. With such a configuration, the insertion opening 12 of the glow starter socket 10 is located on the right side when viewed from the rear of the shelf 4, and the rib 21 and the one-touch clip 22 are inserted into the engagement holes and engaged. As a result, the glow starter socket 10 can be easily attached to the rear surface of the shelf reinforcing plate 6 of the shelf 4 with the insertion opening 12 oriented in the lateral direction, and the positional relationship between the rib 21 and the one-touch clip 22 allows the glow starter socket 10 shown in FIGS. As described above, the side of the insertion opening 12 is slightly inclined and attached. In this state, the glow starter socket 10 is positioned on the rear side in the vertical dimension of the shelf reinforcing plate 6 as shown in the figure, and does not project below the shelf 4. The risk of colliding with the glow starter 8 and dropping off the glow starter 8 is extremely low.

The power plug 17 is connected to a power source (not shown).

These lead wires 13, 13 and 14 are the main body 1
Since it extends laterally from the bottom surface 15 of the rack 1 along the rear surface of the shelf reinforcing plate 6, it does not get caught between the glow starter socket 10 and the shelf reinforcing plate 6 when the glow starter socket 10 is mounted, and does not interfere with the mounting work. Further, since it extends laterally to some extent after coming out of the main body 11, the clip 25 holds the portion weakened by the mold immediately after coming out of the main body 11 on the rear surface of the shelf reinforcing plate 6 without bending. You can Therefore, in particular, the lead wires 13 and 13 can get over the shelf reinforcing plate 6 in a flexible portion, so that the lead wires 13 and 13 are less likely to be cracked even when a product collides.

Even if the mounting angle of the shelf 4 to which the glow starter socket 10 is mounted is tilted in the same manner as the shelf 4 shown in the upper part of FIG. Since it is substantially aligned with the axis of motion, that is, the lateral direction of the rear side of the shelf 4 which extends, the glow starter socket 10
The orientation of the with respect to the vertical direction changes little. Therefore, even if the mounting angle of the shelf 4 is changed, the glow starter socket 10
Since the opening direction of the insertion port 12 can always be directed obliquely downward, it is possible to prevent condensed water flowing down the lower surface of the shelf 4 from entering the inside of the glow starter socket 10.

Incidentally, the glow starter socket 10 of the present invention.
The shape of is not limited to that of the embodiment. For example, a mounting plate portion is integrally provided on the side surface of the main body 11 of the present embodiment, and two holes as mounting portions are formed in the mounting plate portion from the main body 11 to the side, and the holes are used. The glow starter socket may be fixed to the shelf reinforcing plate 6 with a screw.
In that case, the positions of the holes are arranged side by side with respect to the opening direction of the glow starter insertion port.

As described above in detail, according to the invention of claim 1, since the glow starter insertion port of the glow starter socket attached to the lower surface of the shelf is oriented in the lateral direction, the glow starter is projected below the shelf. It is possible to install without. This makes it difficult for the customer's hands and products to collide with the glow starter even when the displayed product is taken in and out, and it is possible to prevent the glow starter from falling out of the glow starter socket.

Further, according to the invention of claim 2, in addition to the above, since the glow starter socket is mounted so that the glow starter insertion port is inclined downward, moisture enters the glow starter socket through the insertion port. It's hard to do. In particular, since the insertion port of the glow starter socket is oriented in the lateral direction, the orientation of the glow starter socket hardly changes even if the shelf mounting angle changes. Therefore, water can be prevented from entering the glow starter socket regardless of the mounting angle of the shelf, and the occurrence of electric leakage or short circuit failure can be prevented.

Next, according to the third aspect of the present invention, since the plurality of mounting portions are formed on the main body of the glow starter socket in the direction orthogonal to the opening direction of the insertion opening, the lower surface of the shelf of the display device is shown. The work for mounting in the lateral direction can be performed extremely easily. In particular, since the line connecting the mounting parts intersects with the opening direction of the insertion opening, the mounting parts corresponding to each are formed at the same height on the lower surface of the shelf, so that By simply attaching the attaching portion so as to correspond to the attached portion, the insertion opening of the glow starter socket can be attached so as to be inclined downward.

Further, according to the invention of claim 4, when attaching the insertion port of the glow starter on the lower surface of the shelf in the lateral direction, the lead wire does not get in the way and the attaching work can be carried out smoothly. Become. Also, by mounting the insertion port in the horizontal direction, the lead wire is also pulled out in the horizontal direction on the opposite side, so it is possible to prevent the weakest part immediately after being pulled out from the main body from being bent. It is also possible to prevent the occurrence of electric leakage due to damage to the lead wires.
