[Industrial applications]

 The present invention relates to a mounting device for an embedded lighting fixture arranged on the back surface of a ceiling.

[0002]

[Prior Art]

 2. Description of the Related Art Conventionally, as a mounting device for this type of embedded lighting fixture, for example, one disclosed in Japanese Utility Model Laid-Open No. 52222/1991 is known. As shown in FIGS. 6 (a) to 6 (c), the mounting hardware applied to this mounting device is diagonally forward from both ends in the width direction of the vertical connecting base portion 1 formed at the rear end. The standing plate portions 2 and 2 extending upward, and a pair of them that are bent outward in the width direction at the upper ends of the center portions of the standing plate portions 2 and 2 and extend forward in parallel with the upper ends of the standing plate portions 2 and 2. Wing pieces 3 and 3, and a head 4 which can be expanded and contracted in the width direction is formed to bulge at the tip of the standing plate portions 2 and 2, and the width direction outside at the rear lower end of the standing plate portions 2 and 2. It has a configuration in which bent flat portions 5 and 5 are formed. Therefore, as shown in FIG. 7, after the fixture body 7 such as a reflection plate is inserted into the opening 6A formed in the ceiling 6 from below, the fixture fitting is attached to the fixture body-side mounting portion 8 and is temporarily fixed. That is, by inserting the head portion 4 into the slit 9 formed in the attachment portion 8 on the instrument body side, the attachment metal fitting temporarily fixed to the attachment portion 8 is pulled down, and the flat surface portions 5, 5 ( Specifically, the downward protrusions formed on the end portions of the flat portions 5 and 5 bite into the back surface of the ceiling 6 or the upper surface of a reinforcing member (not shown) arranged on the back surface of the ceiling 6 to lock the head. The instrument body 7 is fixed to the ceiling 6 by sandwiching both sides of the slit 9 between the rear surface of the portion 4 and the tips of the wing pieces 3 and 3.

However, in the above-mentioned conventional mounting member, the standing plate portions 2 and 2 extend diagonally forward and opposite from each other from both ends in the width direction of the vertical connecting base portion 1 formed at the rear end, and extend in a pair. Since the wing pieces 3 and 3 of the device extend forward in parallel with the upper ends of the standing plate parts 2 and 2, if the mounting part 8 on the instrument body side is straight, no problem will occur, but mounting on the instrument body side When the part 8 is arcuate, the force of holding the attachment part 8 on the instrument body side by the cooperation of the tips of the wing pieces 3 and 3 and the rear surface of the head 4, that is, the tips of the wing pieces 3 and 3 and the head. The holding force on both sides of the slit 9 due to the rear surface of the portion 4 is apt to be significantly reduced, and there is a drawback that the instrument body 7 is unintentionally rattled or moved due to such a large reduction in the holding force. That is, the magnitude of the pressure contact force of the tips of the wing pieces 3, 3 with respect to the arc surface of the attachment part 8 on the equipment body side is as shown by the solid line in FIG. It is the maximum in the state where the attachment part 8 on the instrument main body side is sandwiched by cooperation, and when the facing distance between the standing plate parts 2 and 2 is narrowed due to external factors such as vibration or some other reason, the wing piece 3 , 3 is moved along an arcuate locus that reduces the pressure contact force by separating from the arcuate surface of the mounting portion 8 on the projection plane as shown by the phantom line, and The collapsing force of the mounting portion 8 due to the above-mentioned cooperation significantly decreases, and the device main body 7 causes unintentional rattling and movement.

On the other hand, in FIG. 7, if the outer diameter of the frame 7A at the lower end of the instrument body 7 is the same, the smaller the inner diameter of the opening 6A, the larger the peripheral portion of the opening 6A corresponding to the upper surface of the frame 7A becomes. The instrument body 7 can be stably fixed to the ceiling 6. Therefore, it is required to form the inner diameter of the opening 6A to a size close to the minimum inner diameter of the mounting portion 8 which can be inserted. However, since the mounting bracket is inserted into the opening 6A from below together with the device body 7 in a state where it is temporarily fixed to the mounting portion 8 on the device body side and protrudes outward, the inner diameter of the opening 6A is set to the opening 6A. It will be expanded by the amount corresponding to the outward protrusion of the mounting bracket when inserting. That is, in order to bring the inner diameter of the opening 6A close to the minimum inner diameter, it is necessary to limit the amount of outward protrusion of the fitting when inserted into the opening 6A as small as possible. This outward protrusion amount is obtained by pushing the standing plate portions 2 and 2 of the mounting bracket into the slits 9 until the lower surfaces of the blades 3 and 3 come in contact with both sides of the slit 9 of the mounting portion 8. It can be reduced to a value corresponding to the plate thicknesses of 3 and 3. However, in the conventional mounting bracket, as shown in FIG. 9, the flat surface portions 5 and 5 formed at the lower rear ends of the standing plate portions 2 and 2 interfere with the vertical plate portions 2 and 2 into the slit 9. There is a drawback in that the pushing-in is limited and the amount L of protrusion of the fitting when inserted into the opening 6A becomes large, so that the inner diameter of the opening 6A must be formed considerably larger than the minimum inner diameter.

[0005]

[Problems to be solved by the device]

 The problem to be solved is that if the attachment part on the instrument body side has an arcuate shape, the clamping force on both sides of the slit by the tip end of the winglet and the rear surface of the head tends to decrease, and as the clamping force decreases Due to unintentional rattling or movement of the main body and the large amount of protrusion of the mounting bracket when inserting into the ceiling opening, make the inner diameter of the opening considerably larger than the smallest inner diameter that can be inserted in the mounting section. It is a point that must be done.

[0006]

[Means for Solving the Problems]

 According to the present invention, the mounting brackets are formed by standing up from both ends in the width direction of the lateral connecting base and facing upright plates, and are bent outward in the width direction from the upper ends of these upright plates to extend back and forth. It has a pair of blades, and the tip of each blade is pressed against both sides of the slit, and the rear end is locked to the back surface of the ceiling or the upper surface of the reinforcing member. Even if the attachment part on the instrument body side is arcuate, the clamping force on both sides of the slit by the tip of the wing piece and the rear surface of the head is maintained at a substantially constant level, and when it is inserted into the ceiling opening. The outside projection of the mounting bracket was reduced to a value equivalent to the plate thickness of the winglet, and the purpose of forming the inner diameter of the opening to a size close to the minimum inner diameter that can be inserted in the mounting part was realized.

[0007]

[Action]

 According to the present invention, even if the facing interval of the standing plates is narrowed due to external factors such as vibration or some other reason, the tip of the winglet moves linearly in the projection plane. Therefore, when the facing space of the standing plate portions is narrowed, the tips of the wing pieces approach the arc surface of the mounting portion, and the clamping force of the mounting portion due to the cooperation with the rear surface of the head portion can be increased. . Also, since the rear end of each wing piece is configured to be locked to the back surface of the ceiling or the upper surface of the reinforcing member, the entire standing plate portion is kept until the lower surface of the wing piece contacts both sides of the slit of the mounting portion. Since it can be pushed into the slit, it is possible to reduce the amount of outward protrusion of the mounting bracket when it is inserted into the ceiling opening to a value approximately equivalent to the plate thickness of the blade.

【Example】

 1 (a) to 1 (c) are a front view, a side view and a rear view showing an embodiment of a mounting bracket according to the present invention. In these figures, the mounting brackets include standing plate portions 2 and 2 which are formed to rise from both ends in the width direction of the horizontal connecting base portion 1 and facing each other, and the width direction outside from the upper ends of these standing plate portions 2 and 2. It has a pair of blades 3 and 3 which are bent and extend forward and backward, and a head 4 which can be expanded and contracted in the width direction is bulged at the tip of the standing plates 2 and 2. ing. Therefore, as shown in FIG. 2 and FIG. 3, after inserting the device body 7 such as a reflection plate into the opening 6A formed in the ceiling 6 from below, the mounting metal fitting temporarily fixed to the mounting portion 8 is pulled down. , The front end of each of the wing pieces 3 and 3 is pressed against both sides of the slit 9 and the rear end is locked to the back surface of the ceiling 6 or the upper surface of the reinforcing member (not shown), and the rear surface of the head 4 and the wing. The instrument body 7 is fixed to the ceiling 6 by sandwiching both sides of the slit 9 with the tips of the pieces 3 and 3.

With such a configuration, even if the facing interval between the standing plate portions 2 and 2 is narrowed due to an external factor such as vibration or some other reason, as shown by the solid line and the phantom line in FIG. The tips of 3 and 3 move linearly on the projection plane. Therefore, when the facing space between the standing plate portions 2 and 2 is narrowed, even if the mounting portion 8 is a circular arc surface, the tips of the wing pieces 3 and 3 approach the circular arc surface of the mounting portion 8 and The clamping force of the mounting portion 8 due to the cooperation with the rear surface of the portion 4 is increased. In other words, the clamping force on both sides of the slit 9 between the front ends of the wing pieces 3 and 3 and the rear surface of the head 4 is increased to surely prevent the inconvenient rattling and movement of the instrument body 7 from occurring. You can

Further, since the rear ends of the wing pieces 3 and 3 are configured to be locked to the back surface of the ceiling 6 or the upper surface of the reinforcing member, as shown in FIG. By pushing all of the standing plate portions 2 and 2 into the slit 9 until they come in contact with both sides of the slit of the mounting portion, the outer protrusion amount L1 of the mounting bracket when the ceiling plate 6 is inserted into the opening 6A is set to the wing piece 3, The thickness can be reduced to a value substantially corresponding to the plate thickness t of 3. Therefore, the inner diameter of the opening 6A can be formed to have a size close to the minimum inner diameter through which the mounting portion 8 can be inserted. Therefore, if the outer diameter of the frame 7A at the lower end of the instrument body 7 is the same, the frame 7A By enlarging the peripheral portion of the opening 6A corresponding to the upper surface of the, the instrument body 7 can be stably fixed to the ceiling 6.

[0011]

[Effect of the device]

 As described above, according to the present invention, in the case where the attachment portion on the instrument body side has an arc shape, even if the facing interval of the standing plate portions is narrowed due to external factors such as vibration or some other reason, Since the clamping force on both sides of the slit by the rear surface of the head can be increased, it is possible to reliably prevent the inconvenience of rattling or movement of the instrument body. Also, the amount of protrusion of the mounting bracket when it is inserted into the ceiling opening can be reduced to a value that is approximately equivalent to the plate thickness of the winglet. If the outer diameter of the frame at the lower end of the fixture body is the same, the periphery of the opening corresponding to the upper surface of the frame can be enlarged to stabilize the fixture body on the ceiling. It has the advantage that it can be fixed.
