The other structure is similar to that of the first embodiment.

The operation of this embodiment will be described with reference to FIGS. 12, 17 and 18. That is, FIG.
The frame 16 attached to the device 3 is attached to the device body 3. From this state, the rear end 5 of the push button 18
When 3 is pushed in, the push button 18 moves to the instrument body 3 side in the cradle 30 as shown in FIG.
The tip portion 7 of the slider 4 that is in contact with is pressed, the spring 5 is compressed, and the slider 4 begins to retract in the guide body 8.
At this time, since the button spring 44 has a short dimension, it is not compressed yet and is free. Further, the push button 18 is pushed in, the push portion 55 approaches the edge of the mounting member 40, and the tip portion 7 of the slider 4 is moved to the slider pressing portion 46 of the mounting member 40.
The tip of the button spring 44 starts to be compressed by the stopper piece 52 at a position immediately before being disengaged. At this time, since the finger pressing the push button 18 receives the resistance force of the button spring 44, it can be seen from the feel of the finger that the slider 4 is about to come off. Figure 18 shows push button 1
8, the push portion 55 is projected from the slider pressing portion 46, the tip of the slider 4 is disengaged from the slider pressing portion 46, and the inner end surface of the recess 54 of the push button 18 is pushed to the final pushing position where the stopper piece 52 is locked. Is. In this state, the glove 33 can be lowered from the instrument body 3 and removed. When the hand is released from the push button 18, the push portion 55 retracts from the slider pressing portion 46 by the button spring 44, and the tip portion 7 of the slider 4 projects outward from the through hole 14.

On the other hand, when the globe 33 is attached, when the globe 33 is lifted, the slider pressing portion 46 of the mounting member 40 hits the inclined surface 6 of the tip portion 7 of the slider 4 and pushes the inclined surface 6, so that the slider 4 resists the spring 5. When the slider pressing portion 46 comes out of the inclined surface 6, the distal end portion 7 of the slider 4 enters the mounting bracket 40 of the fitting receiving portion 17 to lock the frame 16, and the push button 18 is pushed. The portion 55 is pressed to project the rear end portion 53, which serves as a finger rest of the push button 18, from the frame 16, and the retaining piece 56 is locked to the side plate 47.

According to this embodiment, the button spring 4 urges the push button 18 in the urging direction of the spring 5 at a position immediately before the tip portion 7 of the slider 4 is disengaged from the fitting receiving portion 17.
The push button 18
Since the tip of the button cannot project inside the frame 16 due to the button spring 44, the push button 18 does not get in the way when the frame 16 is attached to the instrument body 3,
Installation is easy and safe. In this respect, in the first embodiment, since the push button 18 is free, the tip end portion, which is the push portion of the push button 18, may protrude inward until the frame 16 is fitted into the instrument body 3. Then, it interferes with the fitting to the instrument body 3 and causes a hit, which is dangerous and deteriorates the mounting workability.

Secondly, when removing the frame 16 from the instrument body 3,
When the slider 4 is pushed by the push button 18, the button spring 44 is urged immediately before the slider 4 is disengaged from the fitting receiving portion 17 and acts as a resistance on the push button 18, so that the push button 18 suddenly becomes heavy. Frame 1
It can be seen that 6 is disengaged from the instrument body 3. Thirdly, since the button spring 44 acts on a part of the operation range of the push button 18, the push button 18 can be easily operated when the frame 16 is removed. In this respect, as a modification of the first embodiment, it is conceivable to urge the spring of the slider 4 in the direction in which the rear end portion 53 of the push button 18 on which the finger rests protrudes, but there is a margin for the slider 4 to press the slider pressing portion 46. Since the coil spring is large, the coil spring becomes long, the frame 16 needs to be thick, and a force against the spring force of the spring 5 and the spring for the push button 18 is required over the entire stroke of the push button 18. It is necessary to increase the pressing force, and therefore a large force is required to remove the globe 33 attached to the ceiling during lamp replacement or cleaning, which makes it difficult to remove the globe 33. Especially for a woman who cannot exert a great force on her fingertip, the problem that the glove 33 cannot be removed may occur. Also, in the conventional example shown in FIGS. 36 to 39, a large force is required because springs are provided on the push button 76 and the receiving metal fitting 71, respectively, and the frame 16 is thick due to the large margin.

Further, in this embodiment, since the retaining pieces 56 are provided on both sides of the push portion 55 of the push button 18,
Since the retaining piece 56 is located inside the frame 16, it is difficult to see it from the outside, and it serves as a guide when engaging with the side plate 49, so that it is easy to engage and the assembly unit is facilitated. The third embodiment of the present invention is shown in FIGS. That is,
The frame mounting device for this lighting fixture is the same as that of the first embodiment.
The slider 4 has a pair of ridges 63 on its side surface, and the locking tool 1 has a guide body 8 in which a recessed ridge 62 slidably engaged with the ridge 63 is formed on the inner surface and the slider 4 is housed. .. 6
6 (FIG. 23) is an iron plate for reinforcement. In this case, ridge 6
3 and the concave ridge 62 are substantially triangular in cross section, the other specific configurations of the slider 4 and the guide body 8 are the same as those of the second embodiment, and the receiver 2 does not have the button spring 44. Except for this, the second embodiment is the same as the second embodiment.

According to this embodiment, the instrument body 3 of the frame 16
Since the slider 4 to which a load such as the frame 16 and the glove 33 is applied when being attached to the guide body 8 is supported by the guide body 8 in line contact, the slider 4 slides well, and therefore the push button 18
The pushing force can be reduced to facilitate the removal of the frame 16, and the operability when pushing the frame 16 to retract the slider 4 against the spring 5 is improved, so that the frame 16 can be easily attached. Moreover, the structure is simple and can be realized at low cost. In this respect, in the first embodiment, since the slider 4 is supported in surface contact with the guide body 8, the friction resistance is large and the slip is bad. That is, the glove 33 is attached to the instrument body 3
Although the push button 18 is pushed for further removal, since the slider 4 receives the weight of the globe 33 and the frictional resistance with the guide body 8 is large, a large force is required to push the push button 18.

Further, in this embodiment, since the slider 4 slides well, the frame 1 is attached when the globe 33 is attached to the instrument body 3.
While sliding the inclined surface 6 of the slider 4 by the slider pressing portion 46 of the mounting bracket 40 of No. 6, the slider 4 is pushed inward to engage with the mounting bracket 40, since the pushing force of the frame 16 may be small, Can be installed easily.

Further, since the ridges 63 and the ridges 62 are plural, it is possible to prevent the slider 4 from being slid obliquely to hit the inside of the guide body 8 and to make it possible to make a linear movement without lateral shake. .. By smoothing the movement of the slider 4 in this way, the pushing force of the push button 18 at the time of detaching the globe 33 can be reduced, and the detaching operation of the globe 33 is facilitated.

The projection 63 is provided on the guide body 8 and the recess 6 is formed.
2 may be provided on the slider 4. A fourth embodiment of the present invention is shown in FIGS. That is, in the frame mounting device for the lighting fixture, the stopper portions 69 are provided on both sides of the tip portion 7 of the slider 4 in the first and second embodiments.
The locking tool 1 has a guide body 8 for accommodating the slider 4 and the spring 5.

The locking margin of is set long enough in consideration of safety. However, the direction in which the slider 4 of the device body 3 is provided is usually long, and when the material is a wooden product, the frame 16 is molded due to the cutting dimension tolerance (clearance) during processing and the abrasion (slip) of the wooden product during long-term use. Including the case of the product, the frame 16 extends due to the heat of the lamp 42 or the like, and the margin of the slider 4 is reduced. As a result, when the frame 16 is laterally displaced by an external force, the slider pressing portion 46 of the frame 16 is disengaged from the slider 4. There is a risk that the gloves 33 will fall from the device body 3.

When the globe 33 is attached to the instrument body 3, the locking piece 93 needs to be locked in the locking hole 94.
If the size of the frame 16 is too large, the locking piece 93 cannot be locked in the locking hole 94, so that the globe 33 cannot be attached, so that the risk of falling can be prevented. Also the locking tool 1
Also, since there is a pair of receivers 2, if the push button 18 on one side is pressed during cleaning of the glove 33, the end face of the locking piece 93 of the guide fitting 96 hits the locking hole 94 of the instrument body 3 to prevent falling. can do.

Although the groove 97 for escaping the locking piece 93 is formed in the slider 4, the locking piece 93 may be provided so as to be disengaged from the slider 4.
