Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a lighting fixture mounting device for mounting a lighting fixture to a fixture mounting piece extending to the side of a ceiling rosette.

(Prior art) Conventional mounting devices of this type include:
For example, the one shown in Japanese Utility Model Application Publication No. 48-14888 is known. In this case, the top of the lighting fixture is brought into contact with the fixture mounting piece and then screwed into place.

(Problem to be solved by the invention) However, when installing this device, the screws must be tightened while holding the device from below, so the work is troublesome, and it is unstable and dangerous when installed at a high place. It is. Furthermore, since the upper surface of the lighting fixture is supported by a pair of fixture mounting pieces that are spaced relatively apart, large lighting fixtures are prone to sagging or distortion.

On the other hand, as shown in Japanese Utility Model Application Publication No. 52-22687, a device has been proposed in which the mounting portion at the top of the device is pressed into contact with the mounting surface by operating an operating tool provided within the device. In this case, the annular part of the support member having an annular part at the tip is engaged with one claw fixed to the ceiling, and the top of the lighting fixture is inserted through the threaded part on the other end of the support member. A wing nut screwed into a screw presses the lighting fixture against the ceiling and fixes it.

However, this device has a serious problem in that it cannot be attached to a ceiling by using an existing hanging ceiling rosette on a mounting surface such as a ceiling. Furthermore, since it is only fixed in one place with a screw, it has the disadvantage that it cannot be fixed firmly enough. In addition, when installing this type of equipment, the mounting part of the lighting equipment cannot be held in a temporarily fixed state, and the lighting equipment must be supported from below and then suddenly fixed to the mounting surface using the operating tool, making the installation work difficult. is troublesome.

The present invention has been made to solve these conventional drawbacks, and it is possible to attach a lighting fixture to a fixture mounting piece that extends to the side of a ceiling rosette, and also prevents the lighting fixture from sagging or distorting. To provide a lighting equipment mounting device which can prevent this as much as possible, and which is safe, reliable and easy to install after temporarily fixing the lighting equipment.

[Structure of the Invention] (Means for Solving the Problems) The present invention has upward locking portions at each side tip of a sealing rosette disposed on a mounting surface, and the sealing rosettes are provided at approximately 180° intervals from each other. a pair of attachment parts each having a pitch located on the outside of each of the above-mentioned locking parts, and an engaging part provided inside these attachment parts and engaged with the above-mentioned instrument attachment piece; Through a support comprising:
Temporarily fix the lighting fixture body to the fixture mounting piece at a distance from the mounting surface, and temporarily fix it by using an operating tool that is attached to the mounting part of the support and has an operating part exposed inside the lighting fixture body. The structure is characterized in that it is moved to the mounting surface side of the lighting fixture main body and fixed therein.

(Function) When installing a lighting fixture, the present invention engages the support with the fixture mounting piece on the side of the ceiling rosette, thereby attaching the lighting fixture body to the fixture mounting piece through this support. Temporarily secure it away from the mounting surface. Then, it is attached to the mounting part located outside the locking part of the fixture mounting piece, and the lighting fixture body is moved to the mounting surface side using the operating tool whose operating part is exposed inside the lighting fixture body and fixed. do.
To remove lighting equipment, reverse the above procedure.

In the present invention, since the points that support the attached lighting fixture body, that is, the pair of mounting parts or the vicinity thereof, are outside the locking part of the fixture mounting piece, the distance between these mounting parts is increased, and the lighting fixture body Support at both ends. Therefore,
To satisfactorily prevent deformation of the fixture, such as sagging or distortion, even in the case of large-sized lighting fixtures, and to maintain a well-balanced installation state. On the other hand, if the attachment parts are located inside the locking part, the distance between these attachment parts becomes small and the instrument body is supported at the center of the instrument body, which makes the instrument body easily deformed and causes poor balance. It is. In addition, since the lighting fixture body is temporarily fastened and then fixed, there is no need to hold it down while tightening screws as in the conventional case, making the installation work safe, reliable, and simple. Furthermore, since the lighting fixture main body is temporarily fixed at a distance from the mounting surface, it is possible to prevent the lighting fixture main body from inadvertently hitting the mounting surface and damaging the mounting surface when the lighting fixture main body is installed.

Further, in detail regarding the support 6 of this embodiment, both ends of the disc-shaped base body 10 are bent downward, and the tip is further extended in the horizontal direction to form a stepped shape, so that the mounting portion 11 , 11. Further, in the center of the base body 10, there is formed a circular hole 7 having a diameter that allows the sealing rosette 1 to be inserted therethrough, and a pair of notches 8 communicating with the hole 7. Further, a screw hole 16 is formed in the mounting portions 11, 11.

The lighting fixture 12 is comprised of a lighting fixture body 13, for example, which is shaped like an elongated box and has an opening at the top to form a storage section 15 in which the ceiling rosette 1 and the fixture mounting pieces 3, 3 can be accommodated. Note that 14 is a straight tube type fluorescent lamp disposed in the lighting fixture main body 13. Reference numeral 17 denotes a mounting hole formed in the lighting fixture main body 13, and this mounting hole 17 is formed to correspond to the screw hole 16 formed in the support 6.

Reference numeral 18 denotes an operating tool, which in this embodiment is a spring. This operating tool 18 has an operating part exposed inside the lighting equipment main body 13 where the lamp 14 is located.
The tip end is pivotally attached to the mounting hole 17 of the support 6, and the screw hole 16 of the mounting part 11 of the support 6 is
The support 6 is integrally provided with the lighting fixture main body 13 by means of this operation tool 18. The operating tool 18 moves the lighting fixture main body 13, which is temporarily fixed to the fixture mounting pieces 3, 3 apart from the mounting surface 4 via the support 6, toward the mounting surface 4 and fixes it. This operating tool 18 is
A tip having a diameter larger than the inner diameter of the mounting hole 17 of the lighting device main body 13 is acceptable. That is, the screw hole 16 of the support 6 is inserted into the mounting hole 1.
After the lamp 7 is inserted, the tip is formed to have a large diameter by caulking or the like, and the tip is irremovably pivotally attached to the lighting device main body 13. 19 is a switch attached to the lighting fixture main body 13.

Next, the operation of this embodiment will be explained. To attach the lighting fixture main body 13, the support 6 is attached in advance from the bottom side of the lighting fixture main body 13 using the operating tool 18, and the engaging parts 9, 9 of the support 6 are connected to the fixture mounting pieces 3, 3. In this state, the lighting fixture main body 13 is temporarily fixed to the fixture mounting pieces 3, 3 via the support 6 while being spaced apart from the mounting surface 4. In this state, the lighting fixture main body 13 can be rotated in a horizontal plane along the engaging portions 9, 9 and adjusted in a desired direction.

In this temporarily fixed state, the lighting fixture main body 13
Since it is spaced apart from the mounting surface 4, next, the operating tool 18 is operated to move the lighting fixture main body 13 toward the mounting surface 4 side. Then, the lighting fixture body 13 approaches the mounting surface 4, so the lighting fixture body 13 approaches the mounting surface 4.
If the operation of the operating tool 18 is stopped when the lamp contacts the mounting surface 4, the lighting fixture main body 13 can be mounted securely while in contact with the mounting surface 4. Finally, cap 20
Once the luminaire 12 is attached to the ceiling rosette 1, the installation of the luminaire 12 is completed, and the luminaire 12 is ready for use.

In this state, since the operating tool 18 is attached to the mounting part provided with pitches located outside the locking parts 5, 5 of the fixture mounting pieces 3, 3, the point that supports the lighting fixture main body 13 is That is, in this embodiment, the mounting holes 17 are spaced widely from each other and are closer to both ends of the lighting fixture body 13, thereby preventing deformation of the lighting fixture body 13 and stably mounting the lighting fixture body 13 in a well-balanced manner. Further, in this embodiment, the ceiling rosette 1 and the fixture mounting pieces 3 are stored in the housing section 15 of the lighting fixture main body 13, resulting in a streamlined appearance.

Next, it is easily understood from the above explanation that in order to remove the lighting fixture 12 from the mounting surface 4, the procedure described above can be reversed.

FIG. 5 is a longitudinal sectional view showing the main parts of a second embodiment of the present invention. Note that the same parts in the drawings as in FIGS. 1 to 4 are designated by the same reference numerals, and their explanations will be omitted.
This embodiment mainly changes the manufacturing of the operating tool, and includes a stud bolt 23 whose tip is fixed to the mounting portion 11 and extends downward, and an intermediate portion of this stud bolt 23 is provided in the lighting equipment body. Hole 22
It is constructed by a wing nut 24 serving as an operating section, which is screwed into the stud bolt 23 so as to be inserted loosely into the lamp body and come into contact with the lower surface of the lighting fixture body. In this embodiment, by rotating the wing nut 24, the lighting fixture main body 13 can be moved toward the mounting surface and fixed in contact with the mounting surface, so that it is essentially different from the first embodiment. It is easy to understand that similar operations are performed.

6 to 8 show a third embodiment of the present invention. FIG. 6 is a partially cutaway perspective view, FIG. 7 is a partially cutaway longitudinal sectional view, and FIG. 8 is an enlarged perspective view of the main part. In the figure, the same parts as in FIGS. 1 to 4 are given the same reference numerals, and their explanations will be omitted. In this embodiment, the lighting equipment main body 1
Attachment frames 25, 25 are provided on the lower surface of 3 at a distance from the attachment frames 25, 25, the stud bolt 18 is fixed to the support 6 as in the second embodiment, and the middle part of the stud bolt 18 is loosely attached to the attachment frames 25, 25. A wing nut 24 is inserted therethrough and is screwed into the stud bolt 18, 18 on the lower surface side of the mounting frames 25, 25 as an operating part. Therefore, its operation is similar to that of the second embodiment. This embodiment differs from the second embodiment in that the mounting portion 11 of the support 6 can be disposed within the lighting fixture body 13.

9 to 12 show a fourth embodiment of the present invention. 9 and 10 are partially cut away longitudinal sectional views showing the mounting procedure, and FIGS. 11 and 12 are partially cut away perspective views showing the same mounting procedure. Components in the drawings that are the same as those in FIGS. 1 to 4 are designated by the same reference numerals, and their explanations will be omitted. In this embodiment, the operating tool is changed from a screw type to a lever type, that is, the operating tool has a hook part 26 that engages with the mounting part 11 of the support 6, and an intermediate part that is pivoted to the lighting fixture 12. an operating lever 28 as an operating section having one end connected to the hook 26 and gripped at the other end and having elasticity for displacing the hook 26;
It is comprised of a fixing portion 27 that fixes the operating lever 28 against its elasticity. In this embodiment, after the support 6 is engaged with the fixture attachment piece 3 to temporarily fix the fixture body of the lighting fixture 12, when the other end of the operating lever 28 is grasped and rotated,
The lighting fixture body moves toward the mounting surface 4 with respect to the support 6 via the hook portion 26 and stops at the position where it contacts the mounting surface 4, so if you try to rotate the operating lever 28, The operating lever deforms against its elasticity, and eventually engages with the fixing portion 27 and is fixed. As described above, the lighting fixture 12 can be mounted in contact with the mounting surface 4. This embodiment has the advantage that the operating tool can be operated very easily and quickly.

FIG. 13 is a longitudinal sectional view of a main part showing a fifth embodiment of the present invention. This embodiment corresponds to the third embodiment in which a coil spring 30 is interposed between the mounting frame 25 and the mounting portion 11 of the support 6.
By applying a spring force that constantly separates the lighting fixture 12 from the fixture body, the distance from the mounting surface can be maintained well when the lighting fixture body is temporarily fixed.

Although the present invention has been described in detail based on the illustrated embodiments, the present invention is not limited thereto.
For example, if the engaging portion of the support is formed into an arcuate long hole as shown in the figure, the direction within the mounting surface of the lighting device can be easily adjusted, but it is not necessarily a long hole.

[Effects of the Invention] As described in detail above, the present invention includes a pair of pitches located on the outside of the locking portions at the tips of the instrument attachment pieces provided at 180° intervals on the sides of the ceiling rosette. The lighting fixture main body is temporarily fixed to the fixture mounting piece at a distance from the mounting surface via a support having a pair of mounting parts, and the lighting fixture is fixed using an operating tool attached to the mounting part. The main body is moved to the mounting surface and fixed.

Therefore, in the present invention, since the point that supports the attached lighting fixture body, that is, the pair of mounting parts or the vicinity thereof is outside the locking part of the fixture mounting piece, the distance between these mounting parts becomes large. Since the lighting equipment is supported at both ends of the lighting equipment body, even if it is a large lighting equipment, it will not sag.
It is possible to effectively prevent deformation such as distortion and maintain a well-balanced installation state. Furthermore, since the operating tool can be operated with the lighting fixture body temporarily secured, there is no need to support the lighting fixture body while fixing it, and installation is safe and easy. Furthermore, it is possible to effectively prevent the lighting fixture body from inadvertently hitting the mounting surface and damaging the mounting surface.
