2. Description of the Related Art Conventionally, in the United States, a large number of home AV (audio / visual) rooms, so-called home theaters, have been installed in the home during the construction of a house. On the other hand, in Japan, full-fledged AV rooms are not widely used except for some lovers due to differences in housing conditions, but with the spread of DVDs (digital versatile discs) and the like in recent years, AV rooms have become popular. Interest in is growing.

However, if an AV room is to be created, A
V equipment (for example, speakers, projectors, etc.)
Since it has to be attached to the ceiling and / or the wall surface of the room by using a dedicated metal fitting, there is a problem that the room must be modified and the construction time is very long. Furthermore, the wiring of various AV devices is exposed, which makes the appearance unsightly. In addition, it is difficult to use one room as an AV exclusive room under the circumstances that the number of rooms in a house is not so large as in Japan.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described below with reference to the drawings, but the present invention is not limited to these embodiments.

FIG. 1 is a schematic perspective view for explaining a wiring rail according to a preferred embodiment of the present invention. Figure 2
FIG. 2 is a schematic cross-sectional view of the wiring rail of FIG. 1. The wiring rail 1 of the present invention includes a mounting portion 2, a first flange 3 and a second flange 4 provided on both sides of the mounting portion 2, and an outer lid 5.
With.

The mounting portion 2 has opposing walls 21 and 22 on both sides in the width direction orthogonal to the rail longitudinal direction, which extend in a direction orthogonal to both the longitudinal direction and the width direction. Therefore, the mounting portion 2 has a substantially H-shaped cross section when the width direction of the rail is aligned with the horizontal direction. At this time, the opposing walls 21 and 22 extend in the vertical direction. Hereinafter, a case where the width direction of the rail is aligned with the horizontal direction will be described. The mounting portion 2 includes a first locking portion 23 extending from the lower end of the facing wall 21 toward the facing wall 22, and a second locking portion 23 extending from the lower end of the facing wall 22 toward the facing wall 21.
And a locking portion 24. First and second locking portion 23
And 24 lock the attached electric device or its adapter (described later). First and second locking portion 2
Projections 25 and 26 are formed above 3 and 24 so as to face each other. Conductors 27 and 28 are embedded in the ridges 25 and 26, respectively, and the conductor 2
7 and 28 are exposed facing each other. As a result, with the electric device or its adapter locked, the conductor 2
7 and 28 are electrically connected to the terminals of the electric device or the adapter thereof. It should be noted that conductors 27 and 28 are connected to any suitable power source in any suitable manner. For example, when mounting the rail on the ceiling, the conductors 27 and 28 can be connected to the ceiling illumination power supply by using a suitable adapter.

The first and second flanges 3 and 4 are
It has a U-shaped cross section. The first and second flanges 3 and 4 are provided on both sides of the mounting portion 2 such that the U-shaped opening portions 31 and 41 are opposite to the mounting portion 2.

The outer lid 5 is detachably attached to the opening portions 31 and 41. The attached outer lid 5 is the first
Together with the flange 3 to define the first cavity 6
Together with the second flange 4, it defines a second cavity 7. The wiring of a predetermined electric device is accommodated in the first hollow portion 6 and the second hollow portion 7.

Next, with reference to FIGS. 3 and 4, a procedure for mounting the electric device on the wiring rail will be described. The electric device itself has locking portions 23 and 24 of the mounting portion 2.
It may have an attached portion that conforms to, and may be attached via the adapter 8. Here, only the procedure for mounting using the adapter 8 will be described.

FIG. 3 is a schematic view of an adapter used in the present invention, (a) is a front view, (b) is a side view,
(C) is a plan view. FIG. 4 is a schematic diagram showing a procedure for attaching the adapter to the wiring rail. Fig.3 (a)-
As shown in (c), the adapter 8 includes a main body 81, an electric device mounting portion 82, a locking portion 83, a terminal 84, and a pressing portion 85. The locking portion 83 has a central piece 86 extending from the main body 81, and a first overhanging piece 87 and a second overhanging piece 88 that project from the central piece 86 on both sides. The first overhanging piece 87 and the second overhanging piece 88 are respectively the first
The locking portion 23 and the second locking portion 24 are locked. The terminal 84 is vertically spaced apart from the first and second overhanging pieces 87 and 88, and is provided in parallel with the first and second overhanging pieces 87 and 88.

First, as shown in FIG. 4 (a), the protruding portions 87 and 88 of the adapter 8 and the terminal 84 are arranged in the opening 29 of the mounting portion 2 so that the extending directions thereof coincide with the longitudinal direction of the rail. Insert the adapter locking portion 83. In this state, the adapter 8 can freely slide on the wiring rail 1, so that the adapter 8 (as a result, an electric device) can be adjusted to be mounted at any appropriate position according to the purpose.

Next, as shown in FIG. 4B, the adapter 8 is rotated while the main body of the adapter 8 is pressed against the locking portions 23 and 24 of the rail. Since the pressing portion 85 can be elastically moved up and down, when the adapter is rotated 90 degrees, the pressing portion 85 is fitted into the opening 29 of the mounting portion 2 and is elastically biased. At the same time, the overhanging pieces 87 and 88 engage with the first engaging portion 23 and the second engaging portion 24, respectively. At this time, the terminal 84 is electrically connected to the conductor wires 27 and 28 exposed from the ridge.

The electric equipment to be attached is not particularly limited, and any suitable electric equipment is used according to the purpose.
Typically, speakers, projectors, lighting equipment,
Examples include screens, televisions, telephones, and fans.
For example, when configuring an AV system, a speaker, a projector, a lighting fixture, a screen, etc. are attached.

Next, an example of the AV system of the present invention will be described with reference to FIG. FIG. 5 is a schematic diagram illustrating an AV system according to a preferred embodiment of the present invention. This AV system is configured to include the wiring rail. More specifically, a projector, a screen, a speaker, and a lighting unit are attached to a wiring rail attached to a ceiling or a wall surface (typically, a ceiling) of a room. The wiring of the projector, the screen, the speaker, and the lighting means are housed in the cavity of the wiring rail.

Preferably, the AV system of the present invention further includes a control device (eg, power amplifier, DVD player). These control devices are usually arranged on the floor surface (substantially, an audio rack arranged on the floor surface) and are not attached to the rails, but the wiring is housed in the cavity of the rails. Wiring from the control device to the rail is
The wiring cover may be used to attach the wall surface, or the wall may be embedded in the wall of the room. Considering the object of the present invention to construct an inexpensive AV system, it is preferable to use the wiring cover.

Although the rails are attached to the ceiling in an H-shape in the illustrated example, any suitable configuration (for example, T-shape, square-shape, U-shape) can be adopted according to the purpose. Needless to say. Further, although the rail is attached only to the ceiling in the illustrated example, the rail may be attached to the wall surface.

[0025]

As described above, according to the present invention, by using the rails that can be attached to the ceiling or the wall surface and can accommodate the wiring, the construction is easy and the living environment is not damaged, and It is possible to provide an audio-visual system with excellent appearance.
