Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a ceiling embedded frame that allows a detector, lighting equipment, wiring equipment, etc. to be attached to an indoor ceiling board with a single touch.

[Background technology]

Conventionally, when installing wiring devices on indoor ceiling boards, the mounting frame of the wiring devices is fixed to the ceiling board with screws, but it is difficult to use scaffolding in high places such as ceilings. It was difficult to perform screwdriver work in a free state, and the workability was poor.

[Purpose of invention]

The present invention has been made in view of the above points, and it is an object of the present invention to provide a ceiling embedded frame that can be easily attached to a ceiling board with a single touch.

[Disclosure of invention]

That is, in the present invention, vertical pieces 2, 2 are hung from the bottom surface of both ends of a horizontal piece 1, and mounting pieces 3 are each extended outwardly from the lower end of the vertical piece 2, opening downward and having a generally U-shaped cross section. A frame body 4 is formed, vertically long slide grooves 5 are bored in both vertical pieces 2, 2, and a fixture 6 is loosely fitted in the slide groove 5 so as to be able to slide vertically. forming a fixing piece 7 protruding outwardly, urging the fixing tool 6 downward;
The above object is achieved by a ceiling-embedded frame in which a spring member 8 for rotating and biasing the fixing piece 7 of the fixture 6 upward is attached between the fixture 6 and the frame 4.

The present invention will be explained in detail below with reference to Examples. As shown in Fig. 1, vertical pieces 2, 2 are hung downwardly on the lower surface of both ends of the horizontal piece 1, and mounting pieces 3, 3 are attached on the lower ends of the vertical pieces 2, 2, respectively. The frame body 4 has a substantially U-shaped cross section and is open downward. A vertically long slide groove 5 is bored in both the vertical pieces 2, 2, and a fixture 6 is loosely fitted into the slide groove 5 so as to be slidable vertically. As shown in FIG. 2, the fixture 6 is
A narrow upper slide piece 10 is extended from the upper end surface of the fixed piece 7, and a connecting piece 11 is provided at the upper end of the slide piece 10, and a narrow lower slide piece 12 is bent from the lower end surface of the fixed piece 7. An operating piece 13 is provided at the lower end of the lower slide piece 12, and the upper and lower slide pieces 1 of the fixture 6 extend inward.
0 and 12 are loosely fitted into the slide groove 5 to cause the fixture 6 to slide up and down. Fixture 6
A spring member 8 is installed between the connecting piece 11 of the frame 4 and the horizontal piece 1 of the frame 4, and urges the fixing member 6 downward and also pushes the fixing piece 7 of the fixing member 6 upward and outside of the vertical piece 2. It is biased to rotate.

Therefore, the ceiling-embedded frame formed in this way is built into the detector, lighting equipment, and wiring equipment, or these detectors, etc. are fixed to the ceiling-embedded frame. To attach the frame to the indoor ceiling board 9, insert the frame body 4 into the mounting hole 14 made in the ceiling board 9 as shown in FIG. bring it into contact with.
At this time, the fixing piece 7 of the fixture 6 is pushed by the opening side end surface of the ceiling plate 9, and the operating piece 13 protrudes into the inside of the frame 4. Next, as shown in FIG. 2b, push up the operation piece 13 of the fixture 6 with the screwdriver 15 to position the fixing piece 7 on the back side of the ceiling plate 9, and then release the driver 15 in this state, and the spring material 8
At the same time, the fixing member 6 is pressed downward by the elastic force of the fixing member 6, and the fixing piece 7 is rotated outwardly and upwardly, so that the fixing piece 7 is brought into contact with the back surface of the ceiling plate 9 and is pressed downward. In this way, the ceiling plate 9 is held between the fixing piece 7 and the mounting piece 3, and the frame 4 is attached to the ceiling plate 9.
can be fixed. According to this ceiling embedded frame, there is no need to screw screws into the ceiling plate 9 as in the conventional case, so it can be installed even on a thin ceiling plate 9, and the fixing device 6 can be attached from the top and bottom depth of the frame 4. It is possible to mount up to a ceiling board 9 having a thickness equal to the vertical height of . Note that, as shown in FIG. 4, screws 17 may then be inserted into the screw-fastening recesses 16 of the mounting piece 3 from the indoor side to securely fix the mounting piece 3 to the ceiling plate 9. .

[Effect of idea]

As mentioned above, the present invention has vertically long slide grooves drilled in both vertical pieces of the frame, and the fixture is loosely fitted into the slide grooves so as to be able to slide up and down, and the fixture protrudes outward from the vertical pieces. A spring material is installed between the fixture and the frame, which biases the fixture downward and rotates the fixture's fixture upward, so that the frame can be attached to the ceiling. After inserting the fixture into the installation opening of the board, push the fixture upwards with a screwdriver, etc., and then release the driver to force the fixing piece of the fixture to the back side of the ceiling board with the elastic force of the spring material, and attach the fixture to the ceiling board. The frame can be held between the fixing piece and the mounting piece, and the frame can be easily attached to the ceiling by pushing up with a screwdriver, etc., and there is no need to tighten screws or the like as in the past. It is easy to install even in high places such as.
