Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a lighting equipment device used in a ceiling system or the like.

(Prior Art) As is well known, this type of lighting device is installed using a ceiling frame (T-bar) attached to the ceiling, and usually has a pair of parallel side channels. is attached to the ceiling frame using support metal fittings, and the lighting equipment consisting of a socket, reflector, ballast, etc. is supported on this side channel.

By the way, in this type of device, when a space is required to attach a louver, panel, etc. (hereinafter simply referred to as a louver) to the lower part of the open surface at the lower end of the reflector, the side channel is placed above and below the ceiling frame. Selective installation is required.
Conventionally, two types of support metal fittings are prepared and used selectively, but it is necessary to replace and install them each time they are used, which is extremely troublesome work.

(Problem that the invention attempts to solve) This invention is a lighting fixture that is installed using a side channel on a ceiling frame, and the side channel is installed at the bottom of the open surface of the reflector to secure space for installing a louver. The purpose is to make it possible to install the reflector at a higher position by using the same support bracket that was previously used to align the open surface of the reflector with the bottom surface of the ceiling frame. shall be.

(Means for Solving the Problems) This invention provides a lighting device in which a side channel is attached to a ceiling frame fixed to the ceiling, and a lighting device is supported on the side channel.
A plurality of windows are formed vertically along the vertical wall of the support fitting attached to the side channel, and the window is movable up and down along the vertical wall, and the lower part is placed on the head of the ceiling frame. a mounting leg supported by the mounting leg, a window formed in the mounting leg, passing through the window of the mounting leg and selectively inserted into any window of the vertical wall; and the vertical wall inserted through the window. A spring piece having a base portion that engages with the upper edge of the window is fixed to the mounting leg, and a lower end of the spring that extends downward has an engagement member that engages with the ceiling frame from below to prevent lifting. It is characterized by having a section.

(Example) An example of this invention will be described with reference to the drawings. Reference numeral 1 denotes a ceiling frame, which is fixed as a member constituting the ceiling. Reference numeral 2 denotes a lighting fixture, which is constructed by supporting a socket base 4, a socket 5, a stabilizer 6, a reflector plate 7, etc. in a pair of parallel side channels 3.

The above configuration is not particularly different from ordinary devices of this type. According to this invention, a support fitting 9 is fixed to the side channel 3. This support fitting 9 is equipped with a vertical wall 10, and this vertical wall 10 has a plurality of windows 1 arranged in a vertical direction.
1 and 12 are formed.

Reference numeral 13 denotes a mounting leg, which is installed to be movable up and down relative to the vertical wall 10. Specifically, both side edges of the mounting legs 13 are bent, and the bent portions 14 are attached to the vertical wall 10.
It is slidable so as to hold both side edges of the holder. The lower part 15 rests on the head of the ceiling frame 1. A window 16 is formed in the mounting leg 13.

A spring piece 17 is fixed to the mounting leg 13 with a rivet or the like. The spring piece 17 is provided with a base portion 18 that is inserted through the window 16. This base portion 18 is selectively inserted into one of the windows 11 and 12 of the vertical wall 10. The lower part of the spring piece 17 passes through the mounting leg 13, and is provided with an engaging part 19 that bends outward from its tip.

This engaging portion 19 is adapted to engage with the ceiling frame 1 from below, thereby preventing the mounting leg 13 and, by extension, the entire appliance from lifting off from the ceiling frame 1. This engagement can be released by pushing up the claw piece 20.

In the above configuration, normally, as shown in FIG. 1, the base portion 18 of the spring piece 17 is inserted through the window 11 located above the vertical wall 10. In this position, the lower open surface of the reflector 7 and the lower part of the ceiling frame 1 are installed so as to be substantially flush with each other.

Next, when it is necessary to install the louver 21 at the lower part of the open surface of the reflecting plate 7, the base part 18 of the spring piece 17 is pushed out from the inside against the elasticity of the spring piece 17 to be pulled out from the window 11. When the entire device is then raised, the vertical wall 10 also rises, and the platform 18 is automatically inserted into the lower window 12 by its restoring elasticity. By supporting the upper edge of the window 12 with the base portion 18, the entire fixture is supported by the ceiling frame.

At this time, if the lower part of the base part 18 is made into a tapered part 18A as shown in the figure, by simply pushing the entire appliance upward, the lower edge of the window 11 will push up the tapered part 18A, and the base part 18 will automatically close the window. 11 and inserted through the window 12, which is convenient.

By inserting the base portion 18 into the window 12 in this manner, the entire fixture can be supported by the ceiling frame 1. FIG. 2 shows this state. As will be understood, the luminaire 2 is located above the position shown in FIG. As a result, the louver 21 is installed at the lower part of the open surface of the reflecting plate 7.

In addition, as shown in Figure 2, the equipment in the upper position,
When attempting to lower the device to the position shown in FIG.
Just plug it in.

(Effects of the invention) As detailed above, according to this invention, the lighting equipment can be installed in any position vertically and can be prevented from rising from the ceiling frame in any position. Moreover, since the spring piece is shared in both the installation and the floating configuration, the configuration is simplified accordingly.
