<Installation work of lamp 3>
Next, the work in which the worker attaches the lamp 3 to the fixture 2 previously attached to the building portion 9 such as the ceiling and the wall will be described. The fixture 2 can be attached to the building part 9 by fixing it to a hanging bolt suspended from the ceiling, or directly fixing it to the building part such as a ceiling with a fixing tool such as a screw.
(1) First, the operator attaches the tip portion 233 (K) of the lamp 3 to the spring engaging tool 36 in a state where the spring 22 is elastically deformed so that the curvature of the arc portion 232 (E) of the spring 22 becomes large. Connect to. Specifically, the operator is in a state where the spring 22 is elastically deformed so that the arc portion 232 (E) is substantially perpendicular to the instrument bottom surface portion 201 with the second flat portion 226 (L2) as the center of rotation. Passes the spring 22 through the through hole 361 from the side of the first surface 3600 through the tip portion 233 (K) of the spring 22 for both spring engaging tools 36. Then, the operator hooks the tip portion 233 (K) of the spring 22 on the upper edge portion 3610 of the through hole 361 of the spring engaging tool 36, and suspends the lamp 3 from the fixture 2. This state is a state in which the lamp 3 is temporarily attached. The two springs 22 are arranged at both ends of the fixture 2, and the lamp 3 is suspended by the two springs 22 while maintaining a posture substantially parallel to the fixture 2.
(2) Next, when the operator grabs the cover side portion 333 and lifts the lamp 3 to the mounting side (upward Z1), the back surface 232a (Ea) of the arc portion 232 (E) of the spring 22 has a through hole 361. It slides with respect to the upper edge portion 3610 by the restoring force of the spring. The sliding action of the arc portion 232 (E) of the spring 22 is due to the fact that when the operator lifts the lamp 3 to the mounting side (upward Z1), the spring 22 tries to return to its original shape by itself, but the operator The spring 22 returns to its original shape while sliding with respect to the spring engaging tool 36 without worrying about the spring 22.
(3) Further, when the operator pushes up the lamp 3 to the lamp accommodating portion 200 of the fixture 2, the upper end portion 380 of the spring engaging tool 36 comes into contact with the fixture bottom portion 201 of the lamp accommodating portion 200. At this time, the spring 22 suppresses the sliding of the arc portion 232 (E) immediately before the mounting of the lamp 3 on the fixture 2 is completed. Then, when the mounting of the lamp 3 on the fixture 2 is completed, the arc portion 232 (E) of the spring 22 is pressed against the upper edge portion 3610 of the through hole 361 of the spring engaging tool 36, and is above the through hole 361. Positioned with respect to the edge 3610.
At this time, the spring constant when the spring 22 supports the upper edge portion 3610 at the inner portion is much larger than the spring constant when the lamp portion 3 is supported by the tip portion 233 (K). This can be roughly estimated as a cantilever having the first flat portion 221 (L1) as a fixed end because the first flat portion 221 (L1) is fixed to the instrument 2 in the spring 22. In the spring 22, the linear distance (span) between the first bent portion 225 (M1) and the fourth bent portion 231 (M4), which is hardly elastically deformed, is the distance between the first bent portion 225 (M1) and the tip portion 233 ( Span), for example, about 1/5 to 1/6. For cantilever beams, the span affects the spring constant as a cube. That is, the spring constant at the fourth bent portion 231 (M4) is 125 times the spring constant at the tip portion 233 if it is 1/5, and 216 times the spring constant at the tip portion 233 if it is 1/6. .. Therefore, when the operator completes pushing (pushing) the lamp 3 into the lamp accommodating portion 200 of the fixture 2, the inner portion of the fourth bent portion 231 (M4) of the spring 22 is formed on the spring engaging tool 36.
