Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting device for a recessed lighting fixture,
When inserting and fixing the cylindrical device body into a hole in the ceiling surface, the mounting bracket can be inserted into the hole while attached to the device body, and it is easy to do so without using bolts or nuts. It is an object of the present invention to provide a device that can securely attach an instrument main body to a ceiling surface.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view of an embodiment of the present invention, and FIG. 2 is an assembled sectional view of the device attached to a ceiling surface. In these figures, reference numeral 1 denotes a bottomed cylindrical instrument body with one end open, a flange 2 bent outward is provided on the outer peripheral edge of the open end, and a socket 3 is fixed to the inner bottom. A lamp 4 is attached to this. Two narrow guide grooves 5 are provided on the side surface of the instrument body 1 in the embedding direction, that is, in the vertical direction, and a wide mounting bracket insertion hole 6 is provided at the upper end of the guide groove 5 in communication with the guide grooves 5. A plurality of locking holes 7 are provided on both sides or one side of the guide groove 5 and are arranged in parallel with the guide groove 5. This locking hole 7 may be a notch 7' provided in communication with the guide groove 5 as in the embodiment shown in FIG. Reference numeral 8 denotes a pair of mounting brackets, each of which is formed by bending an elastic metal plate such as a spring material into an approximately inverted U shape, and the device body 1 is attached near the top of the bent portion.
A narrow constricted part 9 is formed on both sides to slidably fit into the guide groove 5 of the holding part 10. The other leg piece 11 is an operating part, and has a handle 12 bent in a V-shape in the center and protruding outward, and locking claws 13 bent inward on both sides of the tip.

Next, the installation operation when attaching the appliance body 1 to the ceiling surface will be explained. To install the device on the ceiling surface 14 of the device body 1, first insert the operating parts 11 of the pair of mounting brackets 8 into the device body 1 through the mounting bracket insertion holes 6 of the device body 1, and then The holding part 10 of the mounting bracket 8 is brought into close contact with the instrument body 1 and the mounting bracket 8.
is inserted into the embedded hole 15 from below the ceiling surface 14 and presses the flange 2 against the lower surface of the ceiling surface 14. After that, hold the handle 12 and insert it into the constriction 9 of the mounting bracket 8.
into the guide groove 5 of the instrument body 1 and pull down the mounting bracket 8. Then, the lower end of the holding part 10 of the mounting bracket 8 will hit the upper surface of the ceiling surface 14, so
If you apply further force to pull the handle 12 downward at that position, the holding part 10 will expand outward and elastically deform. By engaging with the hole closest to the plurality of locking holes 7 provided on both sides of one guide groove 5 and locking the pair of mounting brackets 8 to the appliance body 1, the appliance body 1 is attached to the ceiling surface 14. Fixed. As shown in FIG. 4, if a curved elastic part 16 is provided on the operating part 11 of the mounting bracket 8, when the locking pawl 13 is engaged with the locking hole 7, the elasticity of the holding part 10 will be applied. The addition of the deflection of the portion 16 allows this engagement operation to be performed even more smoothly.

As described above, the present invention enables a pair of mounting brackets formed by bending a single elastic plate into an inverted U shape to be slidably attached to the guide groove of the instrument body, and to operate the mounting brackets inside the instrument body. Push the ceiling surface from above to below with one leg of the mounting bracket, engage the locking claw provided on the other leg with the locking hole provided in the device body, and then attach the device body to the ceiling. It is fixed to a surface, and can be inserted into the hole from below the ceiling surface with the mounting bracket attached to the main body of the device in advance. is constricted to form a narrow constricted part 9, and this constricted part 9 is slidably fitted into the guide groove 5 of the device main body 1, so that both legs of the mounting bracket 8 are always almost perpendicular to the ceiling surface. By simply pushing up the fixture body 1, placing its flange 2 against the lower surface of the ceiling, and then pushing down the mounting bracket 8, the holding part 10 of the fixture 8 can be held in the correct position between the ceiling surface and the fixture body. It is easy to install and can be installed accurately. Furthermore, in order to lower the mounting bracket 8, it is sufficient to press the handle 12 provided on the mounting bracket with a fingertip, so there is no risk of damaging the fingertip on the edge of the guide groove 5, and furthermore, the width of the guide groove 5 may be narrow. Therefore, dust is less likely to enter the instrument body from the outside through the guide groove, and light leaking from the guide groove to the outside can also be reduced. Furthermore, since the locking pawl 13 of the mounting bracket is given inward elasticity by the V-shaped bent portion of the handle 12, the locking pawl 13
3 can be easily hooked into the locking hole 7, and there is no fear that the locking claw will come off from the locking hole. Effects such as this can be obtained.
