Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a lighting fixture in which a simple mounting bracket is mounted on the ceiling surface and is directly mounted on the ceiling surface through the mounting bracket. Particularly, the ceiling surface is projected by a crosspiece or the like, and mounting on a ceiling surface such as Japan where the surface is not flat is stable. Directly attached to a ceiling-mounted luminaire.

[0002]

[Prior Art]

 Recently, as the lifestyle has changed, houses with low ceilings have been built, and the number of lighting fixtures directly attached to the ceiling has increased.

[0003] The mounting situation of the ceiling-mounted lighting fixture 1 on the ceiling surface will be described with reference to FIG. 4. In FIG. 4, reference numeral 2 denotes a ceiling surface between Japans in which crosspieces 3 project at predetermined intervals. A hooking sealing body 4 for the power outlet of the lighting fixture 1 is arranged on the middle crosspiece 3. Numeral 5 is a ring-shaped simple mounting metal fitting mounted on the crosspiece 3 around the hooking sealing ring body 14, and is mounted at two places below the peripheral surface thereof for hooking and locking the lighting fixture 1. The screws 6 are provided so as to face each other.

Although not shown, the luminaire 1 comprises a reverse plate-shaped iron plate-shaped fixture body 7 that houses lighting circuit components, and a reflector 8 that closes the lower opening of the fixture body 7 to form a housing. It has a general fixture structure in which a plurality of fluorescent lamps 9 are hung below the reflecting plate 8 and the periphery thereof is covered with a shade 10.

Since the lighting fixture 1 is directly attached to the ceiling, the central portion of the lighting fixture 1 is formed so that its position facing the simple mounting bracket 5 is slightly lowered, and at the position facing the mounting screw 6, a hook locking darma hole. 11 is provided, and when the head of the mounting screw 6 is inserted into the dharma hole 11 and rotated, the lighting fixture 1 is attached. Further, a power source mounting hole 12 is provided in the central portion of the instrument body 7, and a hooking sealing cap 13 connected to a lighting circuit is hooked and connected to a hooking sealing body 14 of the power source. ing.

[Problems to be solved by the device]

 As described above, the lighting fixture 1 directly attached to the ceiling can be easily installed by hooking the lighting fixture 1 by mounting the simple mounting bracket 5 on the crosspiece 3 of the ceiling surface 2. However, if there is a crosspiece 3 on the ceiling surface as in Japan, a gap 14 is formed between the upper surface of the lighting fixture 1 and the ceiling surface 2, which is unstable. Although not shown in particular, in the case of a lighting device having a drawstring switch arranged on the periphery, there is a risk that the lighting device will shake and the device will drop every time the drawstring operation is performed.

Therefore, the present invention has been made in view of the above, and can be stably mounted even on a ceiling surface between Japan, which is not flatly formed by a crosspiece, etc., and there is no risk of dropping equipment. It is intended to provide a direct-mounted luminaire.

[0008]

[Means for Solving the Problems]

 For this reason, the present invention is a ceiling-mounted type lighting fixture that is directly attached to the ceiling surface via a simple mounting bracket, in which a swinging prevention means that abuts against the ceiling surface is provided at the peripheral portion of the upper surface of the main body of the lighting fixture. Is. A compression spring, a bolt and a nut are used as the rocking preventing means, and are arranged between the ceiling surface and the upper surface of the lighting apparatus main body.

[0009]

[Action]

 According to such a configuration of the present invention, the compression spring or the bolt of the rocking prevention means is provided in the gap formed between the upper surface of the peripheral edge of the lighting fixture and the ceiling surface, and the shock of the pulling string operation of the switch is absorbed to cause rattling or the like. The lighting fixture can be stably mounted on the ceiling surface without causing any noise.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side sectional view of a ceiling-mounted type lighting fixture 15 according to the present invention, which shows a state in which, like the lighting fixture 1, a crosspiece 3 is directly attached to a ceiling surface 2 provided so as to project. ing. In this figure, the difference from the luminaire 1 of FIG. 1 is that rocking prevention means 16 that come into contact with the ceiling surface 2 are provided at four peripheral portions of the top surface of the luminaire body 7, and the other points are the same. The same reference numerals are given to the same functional components and the description thereof will be omitted.

FIG. 2 is an enlarged cross-sectional view of an essential part of the above-mentioned rocking prevention means 16 mounting portion, which is arranged on the instrument body 7 at four corners of the peripheral portion. In this rocking prevention means 16, a rod 18 having a seat portion 17 for preventing slipping out is inserted into a mounting hole 19 of the instrument body 7 from below, and an elastic cup 20 is attached to the contact surface with the ceiling surface 2 at the upper end. In addition, the compression spring 21 is interposed between the lower surface of the cup 20 and the upper surface of the instrument body 7.

The compression spring 21 pushes the cup 20 upward due to its elasticity when the lighting fixture 15 is not mounted on the ceiling surface 2, and when the lighting fixture 15 is mounted on the ceiling surface 2, the upper surface of the cup 20 is fixed. Is pushed down by the ceiling surface, and the elasticity of the compression spring 21 and the length of the rod 18 are set to the extent that appropriate elasticity is imparted.

The directly-mounted ceiling-mounted luminaire 15 having the above-mentioned structure resists the elastic force of the compression spring 1 of the rocking preventive means 16 and presses the luminaire 15 against the ceiling surface 2 to provide the conventional luminaire. It can be installed in the same way as 1.

FIG. 3 is another embodiment of the present invention, and is an enlarged cross-sectional view of an essential part in which the rocking prevention means 16 is constituted by bolt means. The rocking preventive means 22 is constructed such that a screwed bolt 23 is planted in a mounting screw hole 24 of the instrument body 7 from below and the head 25 is rotated to adjust the height of the top. . An elastic cup 26 that comes into contact with the ceiling surface 2 is attached to the top of the bolt 23 of the rocking prevention means 22 as in the above.

In the swing preventing means 22 having such a configuration, the height of the top portion of the cup 26 is set to a height position such that it does not come in contact with the ceiling surface, and after mounting the lighting fixture 15 as in the conventional case, The head 25 of the bolt 23 is rotated and attached such that the top of the bolt 26 abuts on the ceiling surface 2.

[0016]

[Effect of the device]

 As described above, the present invention is a ceiling-mounted light fixture that is directly attached to the ceiling surface via a simple mounting bracket, and a rocking prevention means is provided on the peripheral portion of the upper surface of the main body of the fixture to project the swing prevention means. Since the compression spring of the rocking prevention means and the bolt are interposed in the gap between the upper surface of the peripheral edge and the ceiling surface 2, the impact of the drawstring operation of the switch is absorbed and rattling occurs. Without a problem, the lighting fixture can be stably attached to the ceiling surface.
