Abstract

PURPOSE: To perform secure water-proofing operation and mounts lamps with high density by making the lamps at the outermost peripheral positions of respective display units water-proof with finned packing fixed on a panel side and the remaining lamps at inside positions water-proof with press packing fixed on a lamp side. CONSTITUTION: A louver panel 10 which has a louver 11 is provided in front of shelf plates 8a and 8b while matching many holes of a front panel 9 that the respective lamps 3 penetrate. The lamps 3 at the outermost peripheral positions B of the respective display units are made water-proof by sandwiching the finned packing 13 made of an elastic material such as rubber between the louver panel 10 and front panel 9. This finned packing 13 projects into the hole for lamp penetration and is pressed against the flank of the lamp 3 to prevent raindrop from entering the panel. For the remaining lamps 3 at the inside positions A, the press type packing 14 surrounding the lamp circumference is fixed to the lamp side. Consequently, a water-proofing function is obtained and the whole display unit can easily be attached and detached.

Description

[Detailed Description of the Invention] [Field of the Invention] The present invention relates to a large outdoor display device that displays characters, figures, images, etc. by selectively lighting up a large number of lamps that are display elements, and particularly relates to a large outdoor display device that displays characters, figures, images, etc. Regarding the waterproof structure of the lamp.

[Background of the Invention] An outdoor display device is constructed by mounting a plurality of display units on a plurality of shelf boards, and a predetermined number of display elements (lamps) are arranged in a grid pattern vertically and horizontally in front of each display unit. It is installed protrudingly on the The front surface of the shelf board is provided with a front panel having a number of holes through which each lamp of the display unit passes. A waterproof means is provided between this front panel response and the lamp.

Conventional waterproofing means fixing waterproof gaskets to all the lamps of the display unit, and when the display unit is mounted on a shelf board, the waterproof gaskets are pressed against the inner surface of the front panel to waterproof the holes. Ta.

However, when using a press-type waterproof gasket fixed to the lamp side, the gasket curves when pressed against it, requiring a large space around the lamp, and the lamp pitch must be increased. It won't happen.

If such a press-type waterproof gasket is attached to an area where the lamp spacing is narrow, such as a lamp adjacent to the outermost shelf of the display unit, the desired waterproof effect may not be obtained due to insufficient space. be.

As another conventional waterproof means, a waterproof structure has been proposed in which a fin-like gasket is fixed to the front panel side and protrudes into each hole, and the fin-like gasket is brought into pressure contact with the lamp. (Japanese Unexamined Patent Publication No. 103683/1983).

However, such a packing structure fixed on the front panel side has a strong frictional force against the lamp (approximately 1 kg per lamp), and therefore, for example, in a display unit with 48 lamps arranged in 8 rows and 6 tiers, when the unit is attached or removed, It required considerable force and was extremely difficult to attach and detach.

[Object of the Invention] The present invention has been made in view of the drawbacks of the prior art described above. An object of the present invention is to provide an outdoor display device with a waterproof structure that allows easy attachment and detachment.

[Example 1] FIG. 1 is a front view of a display unit constituting a display device according to the present invention. The display unit 1 is constructed by installing lamps 3 (for example, CHD tubes) in a grid pattern of 8 rows and 6 stages on the front of a unit body 2 that houses a power source, a control device, etc. Of these 48 lamps 3, 24 lamps 3 at the outermost position B are waterproofed using fin-like gaskets fixed to the front panel, and 24 lamps 3 at the inner position A (shaded area) are waterproofed. - Waterproofing is applied to lamp 3 using a push-type gasket fixed to the lamp side.

A side view of such a waterproof structure is shown in FIG.

A display unit is mounted between upper and lower shelf boards 8a and gb made of stainless steel plates or the like. Unit body 2 of display unit
A handle 4 for attaching and detaching the unit is provided on the rear surface of the unit. A front panel 9 having a large number of holes through which each lamp 3 passes, and a louver panel 10 having a louver 11 for shielding sunlight aligned with the holes in the front panel 9 are provided on the front surfaces of the shelf boards 8a and 8b. . Each lamp 3 is attached to the unit body 2 via a socket 12. 15 is a waterproof gasket for the cap, and 16 is a waterproof gasket for the socket. A fin-like packing 13 made of an elastic material such as rubber is attached to the louver panel 1 for the lamp 3 at the outermost position B of each display unit.
0 and the front panel 9 to perform waterproofing. However, the peripheral edge of the lamp penetration hole except for the outermost position is just a holed elastic material such as rubber sandwiched between the gasket 13 and the louver panel 10. The fin-like gasket 13 protrudes into the lamp penetration hole and presses against the side surface of the lamp 3 to prevent rainwater from entering the inside of the panel.

For the remaining lamps 3 in the inner position A, a pressing type gasket 14 surrounding the lamp is fixed to the lamp side. This pressing type gasket 14 is pressed against the inner surface of the front panel 9 to prevent rainwater from entering the inside of the panel. shelf board 8a,
3b is provided in a plurality of stages corresponding to the size of the display device, and a plurality of display units are mounted in parallel on each shelf board. In this case, the distance between the outermost adjacent lamps is equal to the distance between the other lamps between vertically and horizontally adjacent display units. Therefore, the space around the lamp at the outermost circumferential position B is narrower than the spaces around other lamps due to the arrangement of shelf boards and the like. The lamp at the outermost position B is provided with a panel-fixed fin-like gasket 13 that can be installed in a narrow space, and the remaining lamps are provided with a pressing-type gasket 14 that does not generate frictional force against the lamp when the lamp is attached or removed. It is set up.

[Effects of the Invention] As explained above, in the present invention, in an outdoor display device consisting of a plurality of display units in which a large number of lamps are arranged at a constant pitch in the vertical and horizontal directions, the outermost lamp of each display unit is For this, a waterproof structure is provided by a fin-like packing fixed to the panel side, and for the remaining inner lamps, a waterproof structure is provided by a press-type packing fixed to the lamp side. Therefore, even if the space around the outermost lamps becomes narrow, a reliable waterproofing effect is achieved, enabling high-density mounting of the lamps and obtaining high-resolution images.Furthermore, there is no frictional resistance against the inner lamps when the unit is attached or detached. Since no pressure is applied, the force required to insert and remove the unit is small, making it easier to attach and detach the unit.
