[0008] The first embodiment will be described below with reference to FIGS.

[0009] 1 to 4 show an appliance mounting device 11, and FIG. 5 shows a lighting appliance 12.

[0010] The fixture mounting device 11 is attached to a pair of suspension bolts 13 protruding downward from a ceiling structure (e.g., ceiling surface c) on the ceiling side, and a power line wired to the ceiling side is connected to the fixture mounting device 11. A lighting fixture 12 is detachably attached to the fixture mounting device 11, and power is supplied to the lighting fixture 12 from the fixture mounting device 11. Thus, the fixture mounting device 11 functions as an adapter for attaching the lighting fixture 12 to the pair of suspension bolts 13 in a detachable manner and capable of supplying power. The power line supplies AC power from, for example, a commercial AC power source.

[0011] The fixture mounting device 11 comprises a mounting member 15 attached to a pair of suspension bolts 13, a fixture mounting section 16 which houses the pair of suspension bolts 13 to which the mounting member 15 is attached and is attached to the mounting member 15, and which removably mounts the lighting fixture 12, and a power supply section 17 which is disposed between the mounting member 15 and the fixture mounting section 16 and supplies power to the lighting fixture 12 attached to the fixture mounting section 16.

[0012] The mounting member 15 is formed of a metal plate. The mounting member 15 includes a disk-shaped mounting plate portion 20, a pair of mounting pieces 21 for mounting the appliance mounting portion 16 provided at symmetrical positions on the outer periphery of the mounting plate portion 20, and a pair of hook portions 22 provided at positions perpendicular to the pair of mounting pieces 21 on the outer periphery of the mounting plate portion 20.

[0013] The mounting plate 20 is provided with a pair of mounting holes 23 at symmetrical positions on the same circumference for mounting to a pair of suspension bolts 13. One mounting hole 23 is a circular hole, and the other mounting hole is an oblong hole that is long in the circumferential direction. Nuts 25 are screwed via washers 24 to the pair of suspension bolts 13 inserted through the pair of mounting holes 23, and the mounting member 15 is attached to the ceiling side (e.g., the ceiling surface c of the ceiling structure) by tightening the nuts 25. A circular opening 26 is provided in the center of the mounting plate 20, through which wiring such as a power line connected to the power supply unit 17 is inserted.

[0014] The pair of mounting pieces 21 are provided at positions on the circumference of the outer periphery of the mounting plate portion 20 that are perpendicular to the pair of mounting holes 23. The pair of mounting pieces 21 are cut and raised in a substantially L-shape so as to protrude downward from the mounting plate portion 20, allowing the appliance mounting portion 16 to be screwed.

[0015] The pair of hooks 22 are provided at positions on the circumference of the outer periphery of the mounting plate 20 that are aligned radially with the pair of mounting holes 23. The pair of hooks 22 are cut and raised in a substantially L-shape so as to protrude downward from the mounting plate 20, and are provided with hook pieces that are bent upward at their tips. The hooks 22 are used to hook a wire connected to the lighting fixture 12 to prevent the lighting fixture 12 from falling off the fixture mounting device 11, or to mount the lighting fixture 12 depending on the type of lighting fixture 12.

[0016] The appliance mounting portion 16 is made of, for example, resin and includes a disk-shaped mounting surface portion 29 and a peripheral surface portion 30 rising upward from the periphery of the mounting surface portion 29. The upper surface side of the appliance mounting portion 16 is open, and an accommodation portion 31 is formed in the internal space to accommodate the tip sides of the pair of hanging bolts 13 to which the mounting member 15 is attached, the washers 24 and nuts 25, and the power supply portion 17.

[0017] The mounting surface portion 29 is provided with a pair of recesses 32 at symmetrical positions on the same circumference, and a pair of mounting holes 33 are provided within the pair of recesses 32. A pair of screws 34 are inserted into the recesses 32 and screwed into the mounting piece portion 21 of the mounting member 15 through the mounting holes 33, thereby mounting the instrument mounting portion 16 to the mounting member 15.

[0018] The mounting surface portion 29 is provided with a pair of mounting holes 35 at positions on the same circumference perpendicular to the pair of recesses 32 and the pair of mounting holes 33. A pair of screws 36 are screwed into the power supply portion 17 through the pair of mounting holes 35, thereby fixing and integrating the appliance mounting portion 16 and the power supply portion 17.

[0019] The mounting surface portion 29 is provided with a pair of insertion holes 37 at positions on the same circumference that are aligned radially with the pair of recesses 32 and the pair of mounting holes 33. The pair of insertion holes 37 are elongated holes that are long in the circumferential direction, and are provided with an enlarged portion 38 at one end in the circumferential direction, whose hole width widens toward the inner diameter side.

[0020] Power supply unit 17 has a cylindrical case 41 made of, for example, resin, is housed in housing portion 31 of fixture mounting portion 16, and is fixed to the upper surface of mounting surface portion 29 by a pair of screws 36 to be integrated. Power supply unit 17 is disposed between the pair of suspension bolts 13 so as not to interfere with the pair of suspension bolts 13, washers 24, and nuts 25 housed in fixture mounting portion 16.

[0021] A pair of wire insertion openings for inserting a pair of power lines are provided on the upper surface of the case 41. A pair of mounting holes for attaching a pair of screws 36 for inserting through the appliance mounting part 16 are provided on the lower surface of the case 41, and a pair of connection holes are provided at positions opposite the pair of insertion holes 37 of the appliance mounting part 16.

[0022] A pair of connection terminals to which the power lines inserted into the pair of wire insertion openings are connected, and a pair of power supply terminals arranged along the edges of the pair of connection holes are arranged inside the case 41. The pair of connection terminals and the pair of power supply terminals are electrically connected to each other at the same pole.

[0023] In this way, the fixture attachment section 16 and the power supply section 17 have the same configuration as a ceiling hook body. Note that the power supply section 17 may be provided integrally with the fixture attachment section 16.

[0024] 5, an example of a high ceiling lighting fixture that is installed in a place with a high ceiling is shown as lighting fixture 12. Note that lighting fixture 12 is not limited to the example of a high ceiling lighting fixture, and may be other lighting fixtures including, for example, base lights that can be installed on the ceiling side.

[0025] The lighting fixture 12 includes a light source unit 44 having a light source, a power supply unit 45 that converts AC power supplied from the fixture mounting device 11 into a predetermined lighting power and supplies it to the light source, and an arm 46 that supports the light source unit 44 and the power supply unit 45.

[0026] The arm 46 is provided with a mounting unit 47 for mounting to the fixture mounting device 11. The mounting unit 47 has a cylindrical case 48 made of, for example, resin, which is rotatably mounted in a circular unit mounting hole 49 provided in the center of the upper surface of the arm 46. The mounting unit 47 is rotatably mounted to the arm 46 around an axis perpendicular to the upper surface of the arm 46, and can support the entire lighting fixture 12 via the arm 46.

[0027] A pair of connecting blades 50, which are a pair of connecting parts bent into a substantially L shape, protrude upward on the same circumference from the upper surface of the case 48. The pair of connecting blades 50 can be inserted vertically through the enlarged parts 38 of the pair of insertion holes 37 of the appliance attachment part 16, and when inserted, move into the pair of insertion holes 37 to be positioned on the pair of power supply terminals of the power supply part 17, electrically connected to the pair of power supply terminals, and mechanically supported.

[0028] The pair of connecting blades 50 of the mounting unit 47 are electrically connected to the power supply unit 45 by, for example, a cable, and AC power supplied from the tool mounting device 11 is supplied to the power supply unit 45.

[0029] To install the appliance mounting device 11, the tip ends of a pair of hanging bolts 13 are passed through a pair of mounting holes 23 in the mounting member 15, and nuts 25 are screwed onto the tip ends of the pair of hanging bolts 13 via washers 24 and tightened, thereby fixing the mounting member 15 to the ceiling side (e.g., ceiling surface c of the ceiling structure).

[0030] A pair of power lines wired on the ceiling side are pulled downward through the opening 26 of the mounting member 15 and connected to the power supply unit 17 fixed to the fixture mounting portion 16.

[0031] While accommodating the tip ends of the pair of suspension bolts 13 to which the mounting member 15 is attached in the accommodating portion 31 of the fixture mounting portion 16, the fixture mounting portion 16 is placed over the mounting member 15 from below, and the fixture mounting portion 16 is fixed to the mounting member 15 with a pair of screws 34, completing the installation of the fixture mounting portion 11. The power supply portion 17 inside the fixture mounting portion 16 is disposed between the pair of suspension bolts 13 accommodated in the fixture mounting portion 16.

[0032] To install the lighting fixture 12, a pair of connecting blades 50 of a mounting unit 47 attached to an arm 46 of the lighting fixture 12 are inserted into the power supply part 17 through the enlarged portions 38 on one end sides of a pair of insertion holes 37 of the fixture mounting part 16, and the mounting unit 47 is rotated in a predetermined mounting direction to move the mounting unit 47 from one end side to the other end side of the insertion hole 37 along the longitudinal direction of the insertion hole 37. Furthermore, in the state moved to the other end side of the insertion hole 37, the mounting unit 47 is placed on a pair of power supply terminals of the power supply part 17, thereby electrically connecting to the pair of power supply terminals and mechanically supporting it.

[0033] By mounting the lighting fixture 12 to the fixture mounting device 11, the lighting fixture 12 is mounted to a pair of suspension bolts 13 via the fixture mounting device 11, and AC power supplied from the fixture mounting device 11 is supplied to the power supply unit 45.

[0034] Therefore, if the fixture mounting device 11 is attached to a pair of suspension bolts 13 in advance, when installing the lighting fixture 12, it is easier to install the lighting fixture 12 by attaching it to the fixture mounting device 11 than by attaching the lighting fixture 12 to the pair of suspension bolts 13, and the wiring work for the power line is also reduced, so that the installation of the lighting fixture 12 can be easily performed.

[0035] Since the arm 46 of the lighting fixture 12 is rotatable with respect to the mounting unit 47 attached to the fixture mounting device 11, the horizontal orientation of the lighting fixture 12 can be adjusted as desired.

[0036] Furthermore, when the lighting fixture 12 is to be removed from the ceiling side for maintenance or replacement, the mounting unit 47 attached to the arm 46 of the lighting fixture 12 is rotated in the removal direction opposite to the mounting direction, and the pair of connecting blades 50 of the mounting unit 47 are moved from the other end side to one end side of the pair of insertion holes 37, and the lighting fixture 12 is removed downwardly through the enlarged portion 38 on the one end side of the pair of insertion holes 37, thereby removing the lighting fixture 12 from the fixture mounting device 11.

[0037] Furthermore, when installing the lighting fixture 12 after maintenance or when installing a new lighting fixture 12, as described above, the lighting fixture 12 can be easily installed by simply attaching the lighting fixture 12 to the fixture mounting device 11.

[0038] As described above, it is possible to provide the fixture mounting device 11 that can easily install the lighting fixture 12 on the pair of suspension bolts 13.

[0039] In addition, since the power supply unit 17 is arranged between a pair of suspension bolts 13 housed in the fixture mounting unit 16, interference with the pair of suspension bolts 13 is prevented and the power supply unit 17 can be arranged within the limited space within the fixture mounting unit 16.

[0040] Next, a second embodiment is shown in FIG.

[0041] A groove 53 is provided along the circumferential direction on the peripheral surface portion 30 of the instrument mounting portion 16. The groove 53 is provided in a pair at symmetrical positions on the circumference of the peripheral surface portion 30, or is provided over the entire circumference of the peripheral surface portion 30.

[0042] By providing the groove portion 53 on the peripheral portion 30 of the fixture mounting portion 16, the lighting fixture 12 can be indirectly or directly temporarily fixed when mounting the lighting fixture 12 to the fixture mounting device 11, thereby improving the ease of installation of the lighting fixture 12.

[0043] The instrument mounting section 16 of the instrument mounting device 11 may be provided with a wiring duct (wiring rail) structure having a pair of conductors through which current flows, while the mounting unit 47 may be provided with a wiring duct plug structure that is detachably attached to the wiring duct and electrically connected to the pair of conductors. The mounting structure between the instrument mounting section 16 and the mounting unit 47 may use a locking mechanism that locks the mounting unit 47 by pushing it up against the instrument mounting section 16 and releases the lock by pushing it up again.

[0044] Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and spirit of the invention, and are included in the scope of the invention and its equivalents described in the claims.
