Patent Law Article 30 Paragraph 2 Applicable Exhibition Date: February 14-16, 2018, Exhibition Name: Supermarket Trade Show, Publisher: E-Seams Co., Ltd., Endo Lighting Co., Ltd.

The present invention relates to a display such as an LED vision, an organic EL display, and a liquid crystal display that can be attached to and detached from a wiring duct (also referred to as a duct rail, a writing rail (registered trademark), a writing duct, a slide outlet, etc.).

The wiring duct developed for lighting equipment is attached to the ceiling or the like, and it is possible to suspend and fix the lighting equipment and supply power. Furthermore, since the wiring duct is linear, it has the convenience of being able to move the position of the installation device along the line direction.

The function of the wiring duct may be utilized in electric appliances other than lighting fixtures. Patent Document 1 shows an example of connecting a thin image display device main body to a wiring duct for lighting. In the thin image display device, a plug once provided on the support member is mechanically fixed to the wiring duct for lighting and electrically connected via the support member (support rod).

<Embodiment 1>
<Display>
The front view, the side view, and the top view of the display 50 according to the present embodiment are shown in FIGS. 1A, 1B, and 1C, respectively. The display 50 is an LED vision, and the main body 55, the power supply case 60, and the mounting base 70 are integrally configured as one housing 90, and the first mounting portion 71 and the second mounting are mounted on the upper surface of the mounting base. A portion 72 and a third mounting portion 73 are provided. By attaching the display 50 to the wiring duct 20 with a plurality of mounting portions on the upper surface of the integrated housing 90 and suspending and fixing the display 50, the display 50 can be installed safely in a harsh environment such as vibration due to an earthquake or wind pressure due to strong wind. You can keep your sex.

<Power case>
The power supply case 60 houses a power supply or the like that converts AC power supplied from the wiring duct into DC power used for the main body 55. The power supply case 60 is made of metal, various resins, or the like. The power supply case 60 can also contain a drive circuit for converting a video signal into a display signal of a display. The power supply and the drive circuit may be installed in another place such as the back side of the display unit in addition to the power supply case 60. In that case, the power supply case 60 may be omitted.

<Mounting part>
FIG. 2 is an enlarged top view of the display 50. On the upper surface of the mounting base 70, there is a stepped portion 75 that is one step higher, and a first mounting portion 71, a second mounting portion 72, and a third mounting portion 73 are provided on the step portion 75. However, the levers 71L, 72L, and 73L of each mounting portion are provided below the upper surface of the step portion 75. By operating the levers 71L, 72L, and 73L, the locking plates 71H, 72H, and 73H having substantially rectangular corners with rounded corners are rotated. The length of the short side of the locking plates 71H, 72H, 73H is shorter than the width of the rail opening 21 of the wiring duct described later, and the length of the long side of the locking plates 71H, 72H, 73H is shorter than the width of the rail opening 21. long. The state shown in FIG. 2 is the mounted state, and by turning each lever 90 ° clockwise from this state, the non-mounted state is set. The height of the step portion 75 (for example, 3 mm) is set to be slightly thicker than the thickness of the levers 71L, 72L, and 73L (for example, 2 mm) so that the mounting state and the non-mounting state can be easily understood by the mounting operator. The movable range of 72L and 73L is defined by the left edge portion 75L and the right edge portion 75R of the step portion 75. The state in which the levers 71L, 72L, and 73L hit the left edge portion 75L can be clearly distinguished from the non-mounted state (shown as the lever 73L (O)), and the state in which the levers 71L, 72L, and 73L hit the right edge portion 75R can be clearly distinguished from the mounted state. Since the tips of the levers 71L, 72L, and 73L are inside the boundary line on the upper surface of the power supply case 60 in the mounted state, the levers 71L, 72L, and 73L cannot be seen by the viewer looking up at the display 50, and the design is such. It has the advantage of being clean.

The first mounting portion 71 has a rotating electrode 71E which is a feeding mechanism from the wiring duct 20 to the power supply case 60. The second mounting portion 72 and the third mounting portion 73 do not have a feeding mechanism, and have only a fixing function by the locking plates 71H, 72H, 73H.

<Wiring duct>
The wiring duct 20 has a substantially rectangular shape, and as shown in FIG. 3 which is a cross-sectional view, a rail opening 21 which is open in the depth direction of the figure, a locking receiver 22, a feeding portion 23, and a top surface 24. It is equipped with. The top surface 24 is a portion in contact with the ceiling surface when the wiring duct 20 is installed.

The first mounting portion 71 is locked by fitting the locking plate 71H of the first mounting portion 71 to the upper surface of the locking receiver 22. At that time, the rotating electrode 71E of the first mounting portion 71 comes into contact with the feeding portion 23, so that power is supplied to the display 50.

The wiring duct 20 is generally fixed to the ceiling, but may be fixed to a raceway or the like which is an elongated member suspended from the ceiling.

<Embodiment 2>
In this embodiment, as shown in FIG. 4, vibration limiting materials 81, 82, 83, and 84 are added to four places on the upper surface of the power supply case 60 of the first embodiment. The tip of the vibration limiting material touches the ceiling 30 in a state where the display is suspended and fixed to the wiring duct, or has a slight gap (for example, about 1 mm) and touches the ceiling when the display vibrates. The material of the contact portion of the vibration limiting material with the ceiling is preferably an elastic material such as rubber, but the material is not limited to this.

When vibration is applied to the display 50 and the display 50 is tilted diagonally, at least one tip of the vibration limiting material 81, 82, 83, 84 hits the ceiling 30, and the display 50 can be prevented from being tilted further diagonally. Therefore, even if the display 50 is a heavy object such as an LED display, it can be safely locked to the wiring duct 20.

The vibration limiting material is installed at the four corners of the upper surface of the power supply case 60, but is not limited to this. For example, the vibration limiting material 81 and 84 on both sides of the wiring duct 20 have the effect of suppressing vibration. Further, the vibration limiting material may project outside the region where the upper surface of the power supply case 60 is projected onto the ceiling, which enhances the effect of vibration limiting.

In the structure provided with the vibration limiting material described in the present embodiment, the display unit is independent of the housing on the mounting base side, and the display unit is a housing on the mounting base side by a rod-shaped support member having one or two rods. It can also be applied to a structure that is supported by the body and the housing on the mounting base side is mounted on the wiring duct.

<Embodiment 3>
