【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. 1 to 4 show an embodiment of the present invention. As shown in FIG. 2, a hook ceiling 2 is attached to the ceiling 1, an intermediate adapter 3 is connected to the hook ceiling 2, and a lighting fixture main body 4 is detachably connected and fixed to the intermediate adapter 3. It has become so. A shade 32 is detachably attached to the luminaire main body 4 to which the lamp 31 is attached so as to cover the luminaire main body 4.

The hook ceiling 2 is adapted to be attached to the ceiling 1 by a fastener 40 such as a wood screw, and a pair of locking hole portions 11 are provided on the lower surface portion. On the upper surface of the intermediate adapter 3 connected to the hook ceiling 2, a pair of substantially inverted L-shaped locking claw fittings 12 are provided to project, and the locking claw fittings 12 are inserted from below the locking hole 11. By pivoting and locking, the intermediate claw 3 is mechanically and electrically connected to the hook ceiling 2 by the locking claw fitting 12.

A lower surface cover 13 is attached to the lower surface of the intermediate adapter 3. The intermediate adapter 3 is provided with a pair of power receiving plug blade receiving groove 14 from the lower surface cover 13 to the center of the intermediate adapter 3 in the vertical direction. A metal fitting (not shown) is arranged so that the blade receiving metal fitting is electrically connected to the locking claw metal fitting 12. The power receiving plug blade receiving groove 14 having the blade receiving member inside thereof constitutes the electrically connected means 8. Further, on both sides of the intermediate adapter 3, two upper and lower engaging grooves 9 are formed.

A holder 7 is provided at the center of the lighting fixture body 4, and a fitting hole 15 is formed at the center of the holder 7 so as to vertically penetrate therethrough. Then, the blade that constitutes the electrical connection means 5 provided in the holder 7 projects into the fitting hole portion 15. A cam 16 is provided in the holder 7 so as to be retractable in the fitting hole portion 15, and the cam 16 is normally projected into the fitting hole portion 15 by the elastic force of the spring 17. The top surface of the cam 16 has a guide surface with an inclined upper surface. When the fitting hole portion 15 is fitted into the intermediate adapter 3, the cam 16 is guided by the inclined guide surface and the cam 16 is guided by the spring 17. The cam 16 is retracted and the cam 16 hits the side surface of the intermediate adapter 3 so that the fitting hole portion 15 can be fitted into the intermediate adapter 3. As shown in FIG. The cam 16 is locked in the locking groove 9 in the state where it is positioned. Therefore, in this embodiment, the mechanical locking means 6 is constituted by the cam 16, the spring 17 and the like. A luminaire main body 4 is provided with a lamp holder 30, and a lamp 31 is attached to the lamp holder 30. The cam 16 as the mechanical locking means 6 is designed to be released by a release button 23 provided so as to project from the lower surface of the holder 7, that is, as shown in FIG. By pushing the button 23, the cam 16 retreats outward against the spring force of the spring 17, and this movement causes the cam 16 to be disengaged from the locking groove 9, so that the holder 7 and the intermediate adapter 3 are separated. The lock is released and the luminaire body 4 can be removed by dropping it downwards.

By the way, the reason why the engaging grooves 9 are provided in the upper and lower two stages in the intermediate adapter 3 is as follows. That is, there are two types of hook ceilings 2 having different heights, and the corresponding engaging grooves 9 are formed in the upper and lower two steps in the intermediate adapter 3 corresponding to the two kinds of hook ceilings 2 having different heights. In the case of the hook ceiling 2 having a high height, the mechanical locking means 6 of the holder 7 is locked in the locking groove 9 on the upper side, so that no gap is generated between the ceiling 1 and the main body 4 of the lighting fixture. In the case of the hook ceiling 2 having a low height, the mechanical locking means 6 of the holder 7 is locked in the lower locking groove 9 so that the space between the ceiling 1 and the luminaire main body 4 is reduced. This is to prevent a gap from being generated, and the lighting fixture main body 4 can be installed so as not to create a gap between the ceiling 1 and the lighting fixture body 4 corresponding to such two kinds of hook ceilings 2. The positional relationship between the two locking grooves 9 is set.

In FIG. 1 to FIG. 4, an opening 10a that opens to the side is provided at the bottom of the lighting equipment main body 4 so as to be positioned to the side of the release button 23. In this embodiment, the opening 10a is provided. A finger hook 10 is provided for hooking a finger other than the finger operating the release button 23 when the release button 23 for releasing the mechanical locking means 6 is operated by the portion 10a. This finger-hooking part 10 is formed by indenting a part of the casing of the lighting fixture body 4 inwardly, and a convex part 10a on which a finger inserted in the finger-hooking part 10 can be hooked is formed in the lower part. ing. Then, as shown in FIG. 1, when the release button 23 is lifted and operated by the thumb, the other finger can be inserted into the finger hook portion 10. The release button 23 can be operated by pushing the release button 23 upward with a thumb in a state where a finger is placed in the finger rest portion 10, and the luminaire main body 4 can be operated by the finger inserted in the finger rest portion 10. The luminaire body 4 can be reliably supported, and the luminaire body 4 can be supported without slipping even if the luminaire body 4 suddenly drops when the cam 16 is disengaged from the locking groove 9. The luminaire main body 4 can be removed without dropping it. Further, since the finger-holding portion 10 is provided in a state where it is opened to the side, it is possible to pull down the lighting fixture body 4 by a finger inserted into the finger-holding portion 10, and to push up the release button 23. Accordingly, the luminaire main body 4 can be pulled down, and the luminaire main body 4 can be easily removed while the release button 23 is being operated.

FIG. 5 shows another embodiment of the present invention, in which a release button 23 as an operating portion for operating the cam 16 is provided in the finger rest portion 10. It is shown. The release button 23 is composed of an operation lever 51 supported by a rotary shaft 50, and an operation protrusion 52 protruding from the operation lever 51 and a cam 16 are connected by a wire 53. . Here, the operation lever 51 is urged in a predetermined direction by a spring 54 so as to urge the operation protrusion 52 toward the intermediate adapter 3.

The operation of the mechanical locking means 6 is performed by rotating the operation lever 51 downward with a finger placed in the finger rest 10 so that the cam 16 is retracted by the wire 53 and the illumination is performed. The connection between the fixture body 4 and the intermediate adapter 3 is released, and the lighting fixture body 4 is detached. Here, if the operation lever 51 can be pivotally moved downward for removal, the removal direction of the luminaire main body 4 and the operation direction of the operation lever 51 coincide with each other. It has good operability when removing the instrument body 4.
