Description

[Detailed description of the invention] 〔Technical field〕 TECHNICAL FIELD This invention relates to recessed lighting fixtures.

[Background technology]

A conventional recessed lighting fixture is shown in FIGS. 10-15. 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. Then, operate the lever 4 as shown by the arrow in FIG. 11 to make the locking spring 3 bite into the side wall of the instrument body 1 and fix it.

At this time, the lower end of the locking spring 3 is locked to the upper surface of the ceiling 5, and the appliance body 1 is attached to the ceiling 5.

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.

Spring 3 that locks onto the top surface of ceiling 5 when fixed with lever 4
Since it is necessary to operate the lever 4 while pressing the lever 4, 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 ice body 1 is inserted into the embedded hole 6 in the ceiling 5, it will not lock as shown in FIGS. 14 and 15. It is necessary to bend the stop spring 3,
It is easy to damage the edge of the embedded hole 6, and since the locking spring 3 needs to be bent as described above, the strength cannot be increased. The strength is weak.

[Purpose of the invention]

Therefore, an object of the present invention is to be able to construct a fixture with one component, to ensure strength, to simplify the installation work compared to the conventional one, and to make it possible to make the fixing device into the embedding hole when inserting the device body into the embedding hole. To provide a built-in lighting fixture that does not cause damage and is easy to remove.

[Disclosure of the invention]

In the first invention, the following parts are formed on a fixture that is inserted from the inside into a vertical slit 7) on the side wall of the instrument body. 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 is 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.

In the second aspect of the invention, the fixture has a substantially U-shaped planar shape, and a guide piece and a locking spring are provided on both sides of the fixture, and the pair of locking springs are connected to the end portion on the pressure contact side to the device body. The width of the fixing member is tapered, and when the fixing member is bent inward, the pressure-contacting end portion is fitted into the vertical slit. The rest is the same as the first invention.

According to these first and second inventions, 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. In addition, the work is simple because the fixing device can be 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.

Further, according to the first aspect of the invention, since the locking spring is provided with a release lever, by lifting this lever, the pressing of the locking spring against the device ice body is released.

According to the second invention, by holding the guide pieces on both sides and bending the U-shaped fixture inward, the locking spring fits into the vertical slit. Therefore, the locking spring is inserted into the device body. Pressure contact is released.

In this way, both the first and second inventions can be removed with a simple operation.

Embodiment Embodiment 2 An embodiment of the first invention is shown in FIGS. 1 to 5.
In the figure, IO is a cylindrical instrument body with a ceiling, and 11 is a fixture. The appliance main body 10 has an outer collar 12 on the lower opening edge that engages with the lower surface of the ceiling, and the side MI! 13 is formed with a pair of vertical slits 14 (one not shown), and furthermore, a fixing tool insertion hole 15 is continuous to the upper end of the vertical slit 14. 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-shape in longitudinal section, and attaching one end to the insertion portion 16.
and the opposite side is a nasal insertion end 17. Insertion part 16
The width is smaller than the width of the vertical slit 14, and the width of the non-inserted end 17 is larger than the width of the vertical slit 14. The lower edge of the insertion portion 16 serves as a ceiling locking surface 18. In addition, locking teeth may be formed on this ceiling locking surface 18, and the upper edge side of the insertion portion 16 is sloped such that the insertion portion 16 side is low and the non-insertion end portion 17 side is high, and the sloped upper piece portion A locking spring 21 is extended from there. 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. 5(A) to 5(D). First, the locking spring 21 of the fixture 11 is brought out from the inside of the fitting hole 15 of the appliance body 10. (A))
, narrow the width of the non-inserted end 17 and slide it into the vertical slit 14 so that the locking spring 21 comes into contact with the outer surface of the side wall of the instrument main body IO (FIG. 5(B)). At this time, when the non-inserted end 17 Due to the spring action of narrowing the width of the end portion 17, the fixing device 11
is temporarily held in the vertical slit 14. In this state, Figure 5 (
Insert the device main body 10 into the embedded hole 24 of the ceiling 23 as shown in B), and after inserting the fixture 11, as shown in FIG. While in contact with each other, the guide piece 22 is rotated around the contact point to press the guide piece 22 against the inner surface of the side wall 13. At this time, the dimensional relationship is set such that the locking spring 21 is pushed up to the extent that it is curved toward the outer surface of the side wall 13 in a posture that projects obliquely upward. Then, as shown in FIG. 5(D), attach the guide piece 22 of the fixture 11 to the side wall 13.
When the fixture 11 is pushed down along the vertical slit 14 while pressing against the inner surface of the ceiling 23, the ceiling locking surface 18 comes into contact with the upper surface of the ceiling 23. Since the locking spring 21 is inclined upward, the fixture 11
The upward movement of the device is resisted by the biting action, and the device body 10 is fixed to the ceiling 23.

When removing, as shown in Figure 5(E), use the fixing tool 11.
Hook your finger 25 on the release lever 20 and lift it. As a result, the locking spring 21 is released from being pressed against the instrument main body 10, and the fixture 11 is easily lifted up. After that, by rotating the fixture 11 inward,
The appliance body 10 can be pulled out 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 can be constructed from one component, and when the fixture body 10 is inserted into the recessed hole 24, the conventional mounting spring does not overhang, which simplifies the work. There is no damage to the insertion hole and there is no restriction on the upper limit of the strength of the spring. Further, the work is simple because the fixture 11 is securely fixed by simply pushing down the fixture 11 along the vertical slit 14 instead of operating a lever while pressing the conventional mounting spring against the ceiling. Moreover, it can be easily removed by pushing up the release lever 20.

6 to 9 show an embodiment of the second invention. In this example, the fixture 11' is curved into a substantially U-shape in plan view,
A pair of locking springs 21' are provided at the upper edges of both side pieces 11a. Furthermore, guide pieces 22' are provided at the non-inserted ends 17 of both side pieces 11a.

The locking spring 21' has a distal end separated from the side piece 11a of the fixture 11, and a width thereof tapered. The arrangement width B (FIG. 7) of the tips of the locking springs 21' is formed so that it is narrower than the width A of the vertical slit 14 of the instrument body 10 when the fixture 11' is bent inward. be.

The other configurations are the same as the embodiment of the first invention.

According to this configuration, the installation work can be performed in the same manner as in the previous embodiment.

Removal is carried out as follows:
By pinching the guide piece 22 located inside with fingers 25 as shown in FIG. 6, the fixture 11' is bent inward. As a result, the tip of the locking spring 21' fits into the vertical slit 14 of the instrument body 10, and the pressing of the instrument body 10 by the locking spring 11' is released. Therefore, by lifting the fixture 11' upward and rotating it inward, the instrument body 10 can be pulled out from the insertion hole 24 in the ceiling 23.

In this way, just by pinching the guide piece 22, the locking spring 21'
The pressure can be released and removal work can be easily performed.

〔Effect of the invention〕
