Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] The present invention is used for a system ceiling in which a ceiling surface is constituted by a ceiling board and equipment such as lighting equipment. Sis,.

The present invention relates to ceiling lighting equipment.

[Conventional technology]

For example, a beam with an inverted T-shaped cross section, so-called T-bar, is stretched over the ceiling surface of an architectural space, and devices such as lighting fixtures are mounted on the T-bar together with the ceiling board to form a system ceiling. use. The system ceiling lighting fixture is as shown in Figure 8.

A socket 3 is placed at each end of a shallow box-shaped main body 20 installed across two parallel ceiling beams, that is, a T-par 1, and a lighting device 4 such as a ballast is installed on the back of the main body 2. A structure in which the above-mentioned sockets 3 are opposed to each other is provided with a partition plate (separator) 6 on the opposite front surface thereof, each having an insertion hole for a fluorescent lamp, so that both inner ends of the system ceiling lighting equipment including the sockets 3 are installed. covering the area. As mentioned above, if the spacing between the KT bars 1 is approximately constant, the width of the system ceiling lighting fixture is determined. Therefore, as shown in A or B in the same figure, T
This creates a difference in distance from par 1012 or 10b. On the other hand, the separator 6 cannot be fixed to the main body 2 of the system ceiling lighting fixture in order to avoid creating an unsightly gap because the T-par 1 that is stretched over the separator 6 is unavoidably slightly twisted or tilted. , One of the bent pieces formed by bending the cross-sectional shape to show a Z shape is mounted and held on the end of the reflector, and the other bent piece is made wider to maintain balance. is constructed so as to cover the top of the socket 7.

[Problem that the invention seeks to solve]

As mentioned above, the separator is for holding one of the bent pieces by placing it on the end of the reflector.

As shown in Fig. 11 above, the separator 6 and the T-bar lob
If the distance between the fluorescent lamp and When installing a louver or transparent cover below.

There have been problems in that the frames of the louvers and translucent covers push up the separators, and that the separators vibrate and generate noise when the system ceiling lighting fixtures are used in combination with air conditioning.

[Means for solving problems]

In the present invention, an elastic body 1 made of a flexible string material is provided in the gap between the bent piece of the separator and the top of the socket to absorb vibrations of the separator and prevent misalignment and noise. It is.

[Effect]

One of the bent pieces of the separator, which is formed by bending its cross-sectional shape into two shapes, is mounted on the end of the reflecting plate.

The other folded piece covers the top of the socket. between the top of the socket and the separator folded piece.

For example, by interposing a flexible elastic body such as sponge rubber, the horizontal displacement of the separator can be prevented by the friction of the elastic body, and the displacement of the separator when it is lifted by attaching a louver or a transparent cover can be prevented. The vibration of the separator in the case of an air-conditioning lighting fixture is absorbed by the compression of the elastic body, and therefore no noise is generated.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

Fig. 1 is a partial sectional view of the back side of the socket in an embodiment of the system ceiling lighting fixture according to the present invention, Fig. 2 is a sectional view of the vicinity of the socket in the direction of the fluorescent lamp of the above embodiment, and Fig. 3 is a separator of the above embodiment. Perspective view, showing the back side! FIG. 4 is a perspective view showing an example of the elastic body in the above embodiment, FIG. 5 is a perspective view showing another example of the elastic body, FIG. 6 is a partial sectional view of a system ceiling lighting fixture with a louver, and FIG. The figure is a sectional view of a ceiling lighting fixture for an air conditioning system. In FIG. 1 and #g2, the main body 2 of the system ceiling lighting fixture is mounted on a T-par 1 and fixed with a set screw 11. On the front of the socket 7 attached to the main body 2,
The separator 6 places one of the bent pieces on the end of the reflector 5, and the other bent piece covers the top of the socket 7, and each end of the separator 6 has two T-parts as shown in FIG. It is placed on the bottom of 1. However, there may be a case where there is a gap between the above-mentioned both ends and the lower side of the T-par 1, and the T-par 1 is held in place by one of the bent pieces. A flexible elastic body 12 is adhered to a position on the lower bent piece of the separator 6 facing the socket 7 to fill the gap between the separator 6 and the top of the socket 7. FIG. 3 is a perspective view of the separator 6 seen from the back side of the socket 7.

The elastic body 12 is a highly flexible elastic body mainly made of a porous material such as sponge rubber, and has a cubic shape as shown in FIG.

The shape is not particularly limited, as long as it has a thickness that can sufficiently fill the gap between the top of the socket 7 and the separator 6. Further, by providing a recess corresponding to the top of the socket 7 as shown in FIG. 5, it is possible to reliably prevent the separator 6 from shifting in the horizontal direction. FIG. 6 is a sectional view showing an example in which the louver frame 13 provided with the louvers 14 is attached to a system ceiling lighting fixture. As shown in FIG. However, there may be a gap C between the lower edge of the

Even in such a case, the gap C can be eliminated by the restoring force of the elastic body 12 against compression. In addition,
The case of attaching the light-transmitting cover is similar to the case of the louver described above. Furthermore, gaps caused by twisting or inclination of the T-par 1 can be similarly prevented.

FIG. 7 is a cross-sectional view of a system ceiling lighting fixture that is used with air conditioning. When the separator 6 is not pressed against the socket 7 by the elastic body 12, the air flow volume and wind speed shown by the arrows are However, according to this embodiment, the elastic body 12 absorbs the vibration, so no noise is generated.

〔Effect of the invention〕

As described above, the system ceiling lighting fixture according to the present invention includes a main body having six lighting devices mounted across two architectural ceiling beams and a predetermined number of sockets, and a main body that covers the front and top portions of the sockets. In the system ceiling lighting fixture having a separator and six reflectors, a flexible elastic body is provided between the top of the socket and the separator.

To prevent displacement of the separator caused by a difference in cross-sectional shape of the ceiling beam, and to eliminate a gap between the ceiling beam and the separator that occurs when a louver or a transparent cover is installed. It is possible to prevent noise caused by the vibration of the separator in system ceiling lighting fixtures used in combination with air conditioning, and by applying separators of the same size to the separators in the various different cases described above, it is possible to improve the mass productivity and low cost of system ceiling lighting fixtures. It is possible to achieve cost reduction.
