The adapter has an engaging step on the side surface and a lower surface connecting portion on the lower surface, and is electrically and mechanically connected to the hooking sealing body. The luminaire has a holder that is held by the adapter having a locking piece that is locked to the locking step. Plugs have a hooking edge for hooking connected to the lower surface connecting unit, when engagement of the said adapter holder of incomplete, the plug is in contact with the lower surface of the holder, engagement for holding said holder Part.

  The said structure WHEREIN: The cyclic | annular protrusion with a circular arc shape is provided in the contact surface with the said plug of the said holder.

  In the above configuration, the adapter exposes a lock release button on a lower surface, and the plug is configured to hide the lock release button in a connected state.

  In the above configuration, the locking piece has a release operation portion exposed from the lower surface of the holder, and the plug covers the operation surface of the release operation portion so as to obstruct the operation of the release operation portion by the connection.

  In the above-described configuration, the locking piece has a release operation portion exposed from the lower surface of the holder, and the plug prevents the release operation of the release operation portion by the connection.

  According to the lighting fixture mounting apparatus of the present invention, since the locking between the hooking ceiling body or adapter and the holder is incomplete due to insufficient mounting of the lighting fixture or the like, the lighting fixture should be removed from the hooking ceiling body or adapter. Even if it comes off, the holder of the lighting fixture can be held by the engaging portion, so there is no fear of the fixture falling.

  Since the annular projecting ridge having an arcuate cross section is provided on the contact surface of the holder with the plug, the contact between the holder and the plug is a linear contact, so that the frictional force is small and the plug can be easily attached.

  Because the adapter exposes the unlock button on the bottom surface and the plug is hidden when the plug is connected, the unlock button of the adapter is hidden when the plug is attached. There is no sudden drop during removal and it is safe.

  The locking piece has a release operation part, the holder exposes the release operation part on the lower surface, and the plug covers the operation surface of the release operation part so as to obstruct the operation of the release operation part by the connection. When the plug is attached, the release operation part of the holder is hidden, so the instrument cannot be removed without removing the plug first, so there is no mistake in the removal operation sequence, and there is no sudden drop of the instrument during removal. .

Since the movement of the operation unit is regulated, the locking piece does not move even when an external force such as an earthquake is applied, so there is no risk of the locking being released and falling.

  A first embodiment of the present invention will be described with reference to FIGS. That is, this lighting fixture mounting apparatus locks the lighting fixture 8 by locking the locking piece 5 of the holder 4 provided on the lighting fixture 8 to the locking step 3 of the hook ceiling body 2 installed on the ceiling surface 1. The hook sealing body 2 and the lighting fixture 8 are electrically connected by a plug 6 that is mechanically held by the hook sealing body 2 and connected to the lower surface connecting portion 2a of the hook sealing body 2. In such a lighting fixture mounting apparatus, in particular, when the plug 6 is connected to the lower surface connecting portion 2a, the engaging piece 5 is engaged with the holder 4 and the engaging piece 5 is engaged with the engaging step 3. The plug 6 is provided with an engagement portion 7 for preventing a failure of the engagement between the engagement piece 3 and the engagement piece 5.

  The hook sealing body 2 has a substantially cylindrical shape directly attached to the ceiling surface 1 and has a collar-like locking step 3 at the lower end portion. The lower surface connection portion 2a has a pair of arc-shaped connection holes and an inside thereof. And a hooking tool (not shown) for electrically and mechanically connecting the plug 6.

  In the lighting fixture 8, as shown in FIG. 2, 9 is a fixture body, 10 is a body cover, 11 is a ring lamp, and 12 is a globe.

  As shown in FIGS. 3 and 4, the holder 4 is formed with a fitting hole 14 of a size that allows the holder main body 13 to be fitted to the hooking sealing body 2 at the center. A recess 15 that is opened in a notch shape is formed on both of the holes 14, and the recess 15 is covered with a cover 16 to form a locking piece protrusion opening 17 that faces the fitting hole 14. A lower surface opening 18 is formed in the cover 16. In the recess 15, a locking piece 5 and a spring 20 using a coil spring are housed, and a locking claw 21 at the tip of the locking piece 5 is passed through the locking piece protrusion opening 17 so as to be able to advance and retract. Protrusively biased inward. The locking claw 21 forms a taper surface on the upper surface side to facilitate locking of the hooking sealing body 2 to the locking step 3. Further, the release operation portion 22 is suspended from the locking piece 5 and protrudes downward through the lower surface opening 18 of the cover 16.

  This holder 4 is attached to the central opening of the instrument body 9. When the fitting hole 14 of the holder 4 attached to the instrument body 9 is pushed up so as to be fitted to the hooking sealing body 2, the taper surface of the locking claw 21 comes into contact with the lower side of the locking step 3 and resists the spring 20. Then, when the locking claw 21 slides and the locking claw 21 moves backward, and the locking claw 21 gets over the locking level 3, the spring 20 is restored and the locking claw 21 is moved to the locking level as shown in FIG. 3 on the upper side. As a result, the lighting fixture 8 is mechanically attached to the hooking sealing body 2.

  On the other hand, when the lighting fixture 8 is removed from the hooking ceiling body 2, when the release operation portion 22 of the locking piece 5 is slid against the spring 20 in a direction away from the fitting hole 14, the locking claw 21 is locked. 3 can be detached and the lighting fixture 8 can be detached from the hooking sealing body 2.

Connected mechanically and mechanically. The engaging portion 7 extends outward from the bottom (upper surface) side of the trapezoid from both ends in the longitudinal direction so that the plug 6 is longer than the outer diameter of the hooking sealing body 2, and connects the plug 6. At this time, the holder 4 is pushed up. That is, as shown in FIG. 6, the length L of the plug 6 is greater than the outer diameter of the hooking sealing body 2. Conventionally, the reverse is true, and the relationship of the length of the plug 6 <the outside diameter of the hooking sealing body is established. 6 b is a lead wire of the plug 6.

  FIG. 5 shows a state in which one of the locking claws 21 of the holder 4 is locked to the locking step 3, and the other one of the locking claws 21 is not yet locked to the locking step 3 and the holder 4 is inclined. . In such a state, when the lighting fixture 8 is tilted, the one locking piece 21 is locked first, and if the mounting operation is stopped halfway, the lighting fixture 8 may be held in a single state. There is. When the plug 6 is hooked on the lower surface connecting portion 2a of the hooking sealing body 2 in this state, the engaging portion 7 at the end of the plug 6 comes into contact with the lower side of the holder 4, and the hooking blade 6a of the plug 6 keeps the hooking tool in this state. Can not be locked to. When the holder 4 is pushed up by the engaging portion 7 of the plug 6 in the state of FIG. 1 or the instrument body 8 is pushed up to the correct posture, the hooking blade 6a of the plug 6 can be connected to the hooking tool. At the mounting position of the plug 6 (the position where the plug end surface 6c and the sealing end surface 2c are in contact), the locking step 3 of the hooking sealing body 2 and the locking piece 5 of the holder 4 are equal in height, and the locking claw 21 is locked. Fully locked to 3.
