Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a recessed lighting fixture.

[Conventional technology]

Conventional recessed lighting fixtures are shown in FIGS. 6-11. That is, a vertical mounting slit 2 is formed in the side wall of the device body 1, a locking spring 3 is engaged from the outside of the vertical slit 2, a lever 4 is engaged from the inside, and the lever 4 is fitted into the locking spring 3. together,
The lever 4 is operated as shown by the arrow in FIG. 7, and the locking spring 3 is bitten into the side wall of the instrument body 1 and fixed.
At this time, the lower end of the locking spring 3 is locked to the upper surface of the ceiling 5, and the appliance main body 1 is attached to the ceiling 5.

[Problem to be solved by the invention]

However, this embedded lighting fixture has the following drawbacks. That is, since two parts, the locking spring 3 and the lever 4, are required, the cost is high.
When fixing with the lever 4, it is necessary to operate the lever 4 while pressing the locking spring 3 against the upper surface of the ceiling 5, so the installation work is troublesome. Even when the lever 4 is loosened, the locking spring 3 protrudes from the outside of the device body 1, so when the device body 1 is inserted into the embedded hole 6 in the ceiling 5, it will lock as shown in Figs. 10 and 11. It is necessary to bend the spring 3, and the embedding hole 6
The edges are easily damaged. Furthermore, since it is necessary to bend the locking spring 3 as described above, the strength cannot be increased, and if the appliance main body 1 is heavy, the strength after fixing to the ceiling is weak.

The purpose of the present invention is to make the fixing device consist of one part, ensure strength, simplify the installation work compared to the conventional ones, and prevent damage to the mounting hole when inserting the instrument body into the mounting hole. The idea is to provide recessed lighting fixtures that are easy to remove and can be easily removed.

[Means to solve the problem]

According to the present invention, a fixture having a substantially inverted U-shape in vertical cross section is inserted into a vertical slit in a side wall of an instrument body from the inside, and has the following parts formed therein. That is, an insertion portion inserted into the vertical slit, a guide piece that comes into contact with the inner surface of the side wall of the device body, and a guide piece that is loosely fitted through the insertion hole at the upper end of the vertical slit and pressed against the outside of the side wall of the device body and pushed upward. The apparatus is provided with a locking spring that prevents movement and rotation, and a release lever for lifting operation that is provided on the locking spring and projects from the vertical slit into the instrument body.

[Effect]

According to this invention, the following effects can be obtained. In other words, the fixture can be constructed from a single component, and when inserting the main body of the device into the hole in the ceiling, the conventional mounting spring does not overhang, making the work easier, without damaging the hole, and reducing the strength of the spring. There is no restriction on the upper limit of the weight, and the strength against the weight of the device can be ensured. Further, the work is simple because the fixing device is securely fixed by simply pushing down the fixing tool along the vertical slit, instead of operating the lever while pressing the conventional mounting spring against the ceiling. Further, since a release lever is provided on the locking spring, by lifting the lever, the pressing of the locking spring against the instrument body is released.

〔Example〕

An embodiment of the invention is shown in FIGS. 1 to 5. In FIG. 2, numeral 10 is a cylindrical instrument body, and numeral 11 is a fixture. The device main body 10 has an outer collar 12 on the opening edge of the lower end that is fixed to the lower surface of the ceiling, a pair of vertical slits 14 (one not shown) is formed in the side wall 13, and a fixture is fitted into the upper end of the vertical slits 14. The insertion hole 15 is continuous. A lamp socket (not shown) is installed vertically on the inner ceiling of the appliance body 10.

As shown in FIGS. 1 to 4, the fixture 11 is made by bending a spring material into a U-shaped vertical section, with one end serving as an insertion portion 16 and the opposite end serving as a non-insertion end 17. The width of the insertion portion 16 is equal to the width of the vertical slit 14.
The width of the non-inserted end portion 17 is larger than the width of the vertical slit 14. Insertion part 1
The lower edge of 6 serves as a ceiling locking surface 18. Note that locking teeth may be formed on this ceiling locking surface 18. Further, the upper edge of the insertion portion 16 is sloped such that the insertion portion 16 side is lower and the non-insertion end portion 17 side is higher, and a locking spring 21 is extended from the sloped upper piece. The locking spring 21 has a bifurcated tip and a release lever 20 extending therefrom. The non-inserted end 17 is bent outward to form a guide piece 22.

When mounting on the ceiling, proceed as shown in FIGS. 5A to 5D. First, the locking spring 21 of the fixture 11 is brought out from the inside of the insertion hole 15 of the instrument body 10 (FIG. 5A), and the non-inserted end 17 is slid into the vertical slit 14 by narrowing the width thereof. The locking spring 21 is attached to the instrument body 1
0 (FIG. 5B). At this time, the fixing tool 11 is inserted into the vertical slit 14 due to the spring action caused by narrowing the width of the non-inserted end 17.
will be temporarily held. In this state, insert the device main body 10 into the embedded hole 24 of the ceiling 23 as shown in FIG. 5B, and after inserting the fixture 11 as shown in FIG.
While the tip of the guide piece 22 is in contact with the outer surface of the side wall 13, the guide piece 22 is rotated around the contact point.
Press it against the inner surface of the At this time, the dimensional relationship is set such that the locking spring 21 is pushed up to the extent that it curves toward the outer surface of the side wall 13 in a posture that projects obliquely upward. Then, as shown in FIG. 5D, when the fixture 11 is pushed down along the vertical slit 14 while pressing the guide piece 22 of the fixture 11 against the inner surface of the side wall 13, the ceiling locking surface 18 hits the top surface of the ceiling 23. . Since the locking spring 21 is inclined upward, the upward movement of the fixture 11 is resisted by biting action, and the device main body 10 is fixed to the ceiling 23. The operations shown in FIGS. 5C to D can be performed with one hand by grasping the lower surface of the instrument body 10 and the guide piece 22.

To remove it, hook your finger 25 on the release lever 20 of the fixture 11 and lift it up, as shown in FIG. 5E. As a result, the device main body 1 due to the locking spring 21
0 is released, and the fixture 11 is easily lifted up. Thereafter, by rotating the fixture 11 inward, the instrument main body 10 can be removed from the embedding hole 24 in the ceiling 23. In this way, the pressure exerted by the locking spring 21 can be easily released and the instrument main body 10 can be removed.

In the recessed lighting fixture with this configuration, the fixture 11 is one
In addition to being able to be constructed from parts, the conventional mounting spring does not overhang when inserting the instrument body 10 into the embedding hole 24, making the work easier, without damaging the embedding hole, and without any upper limit on the strength of the spring. . In addition, instead of operating the lever while pressing the conventional mounting spring against the ceiling, simply attach the fixture 11 to the vertical slit 14.
The work is easy as it is securely fixed just by pushing down along the In this case, since the push-down work (Fig. 5 C, D) can be performed with one hand as described above, the remaining hand can be used to support the body during work at a high position, making the work safe and easy. . In addition, since the insertion portion 16 is configured to engage with the ceiling and come into pressure contact with the inner and outer surfaces of the instrument body 10 by the guide piece 22 and the locking spring 21, the vertical height of the fixture 11 should be made smaller than that of the instrument body 10. It can be made low enough. Therefore, the vertical movement range of the fixture 11 with respect to the vertical slit 14 of the instrument body 10 is wide, and
Even if there is a large difference in the thickness of the ceiling 23, the difference can be absorbed. Furthermore, when removing the instrument main body 10, it can be easily removed by pushing up the release lever 20.

〔Effect of the invention〕

The recessed lighting fixture of the present invention includes a fixture that is inserted from the inside into a vertical slit in the side wall of the fixture body,
This fixture consists of a guide piece that contacts the inner surface of the instrument body, and a locking spring that is loosely fitted through the fitting hole at the upper end of the vertical slit and presses against the outer surface of the instrument body to prevent upward movement and prevent rotation. The fixing device can be constructed from a single component, and when the device body is inserted into the hole in the ceiling, the conventional mounting spring does not overhang, making the work easier and preventing damage to the hole. Moreover, there is no restriction on the upper limit of the strength of the spring, and the strength against the weight of the device can be ensured. Further, the work is simple because the fixing device is securely fixed by simply pushing down the fixing tool along the vertical slit, instead of operating a lever while pressing the conventional mounting spring against the ceiling. Therefore, the installation work can be carried out with one hand, and when working on a high ceiling, the remaining hand can be used to support the worker's body, etc., and the work can be carried out safely. Furthermore, the vertical movement range of the fixture can be increased with respect to the vertical slit of the fixture body, and even if there is a large difference in the thickness of the ceiling, the difference can be absorbed.

Further, since a release lever is provided on the locking spring, by lifting the lever, the pressing of the locking spring against the instrument body is released. Thereafter, by holding the guide piece and narrowing the width of the fixture having an inverted U-shaped cross section, the fixture can be easily removed. This has the effect that the instrument body can be easily removed.
