In addition, the yoke 14 has curved pivot pieces 20 at both ends that are curved upward in a semicircular shape to serve as pivot guides when attaching the shade 15.
and a shade locking claw 21a formed of a cut and raised piece on the lower surface of the bottom plate 16.

Two pieces 21b are provided on the left and right sides.

These shade locking claws 21a and 21b are formed in a hook shape, and each faces toward the end of the yoke 14.

The shade 15 has each small shade hook 21a, 2 of the yoke 14.
Locking holes 22a and 22b into which 1b engages are provided on the top surface.

This locking hole 22a. Reference numeral 22b denotes both shade engaging claws 21a arranged in pairs.

21b is formed in a size that allows insertion.

On the upper surface of the shade 15 are both side plates 12a of the instrument body 12.

A V-shaped projection 30 is provided which engages the inner surface of 12b.

A pair of engagement holes 22a in the width direction of the shade 15. 22b, one of the locking holes 22b is provided with a movable stopper piece 23 for engagement with the shade locking claw 21b.

The movable stopper piece 23 is supported by a presser metal fitting 24 attached to the inner surface of the shade 15 so as to be slidable in the width direction of the shade 15.

Further, the movable stopper piece 23 is biased in a direction to close the locking hole 22b by a spring member 25 interposed between the presser metal fitting 24 and the movable stopper piece 23.

The spring member 25 is made of a tension coil spring.

The movable stopper piece 23 has a bent piece part 23a for an unlatching operation that projects upward from a slide hole 26 provided in the shade 15.

A portal-shaped engagement protrusion 27 that engages the curved pivot piece 2o of the yoke 14 is provided on the side of the shade 15 where the movable stopper piece 23 is provided and on the reflection side.

Note that the shade 15 has a reflector plate 6 and a lamp socket 5 shown in FIG.

In FIG. 8, 28 is a connection cord provided on the instrument body, and 29 is a connection cord provided on the shade.

With this configuration, when installing, after attaching the yoke 14 to the instrument body 12 on the floor as shown in FIG.
This appliance main body 12 is attached to the ceiling.

Next, after connecting the power supply wire to the appliance main body 12, the shade 15 is attached as follows.

That is, first, as shown in FIG. 8, hook the gate-shaped engagement protrusion 27 of the shade 15 onto the curved pivot piece 20 at one end of the yoke 14, and connect the connecting cord between the instrument body 12 side and the shade 15 side. 28.
Connect 29.

Next, the shade 15 is pushed up so as to rotate about the curved pivot piece 20 as a fulcrum, as shown by the arrow P.

As a result, the right side of the left shade engaging claw 21a of the yoke 14 in the figure is guided by the engaging hole 22a of the shade 15, and the shade 15 is moved slightly to the right (Fig. 9).
.

When the shade 15 is further pushed up, the hook portion on the right side of the small shade engagement claw 21b on the right side of the yoke 14 pushes open the movable stopper piece 23 as shown in FIG. 10 and is fitted into the locking hole 22b.

When completely fitted, the movable stopper piece 23 closes the locking hole 22b by the biasing force of the spring member 25 and engages with the shade locking claw 21b.

In this way, attachment of the shade 15 is completed.

When removing the shade 15, the movable stopper piece 23 is opened by pulling the bent piece 23a of the movable stopper piece 23, thereby releasing the locking of the shade locking claw 21b.

In this way, by simply hooking the gate-shaped engaging protrusion 27 on one side of the shade 15 to one end of the yoke 14 and pushing up the hook using the portion as a pivot point, the shade locking claws 21a, 21b and the locking hole 22a are connected. , 22b and the installation of the shade 15 is completed, so that the installation of the shade 15 can be easily and safely carried out even at high places.

It is safe and will not come off.

That is, even if the shade 15 is moved to the right in the figure by an external force, the movable stopper piece 23 remains engaged with the small shade engagement pawl 21b due to the biasing force of the spring member 25.

Furthermore, even if the left shade locking pawl 21a is temporarily removed, the shade 15 remains horizontal because the gate-shaped engaging protrusion 27 of the shade 15 is engaged with the curved pivot piece 20 of the yoke 14. Since the posture is maintained, the locking claw 21b1 on the movable stopper piece 28 side will not come off.

Therefore, when the external force is removed, the shade 15 is returned to its original position by the urging force of the spring member 25 of the movable stopper piece 23, and the shade locking claw 21a, which has been disengaged, is again engaged.

Therefore, there is no problem of the shade 15 falling off.

In addition, during the installation work of the shade 15, the shade 15 can be engaged with one end of the yoke 14 as described above, so the connection cords 28 and 29 can be connected in this state, so that the shade 15 can be temporarily suspended. Temporary hanging is not necessary, and in this respect as well, the work of attaching the shade 15 is simplified.

Further, since the yoke 14 is attached by engaging the main body engaging claw 19 with the engaging hole 18 of the instrument main body 12, the yoke 14 can be easily attached.

Moreover, on the upper surface of the shade 15, the side plates 1 of the instrument main body 12 are placed.
Since the V-shaped protrusions 30 that engage with the inner surfaces of the V-shaped protrusions 2a and 12b are provided, even if an external force is applied to the instrument body 12 that causes the side plates 12a and 12b to bend inward, the V-shaped protrusions 3
0 prevents deflection of the side plates 12a and 12b.

Therefore, the main body locking claw 19 of the yoke 14 is attached to the instrument main body 12.
Therefore, the shade 15 is prevented from falling off from the instrument body 12 together with the yoke 14.

The shade 15 has a built-in reflector, but since the shade 15 with the reflector can be easily attached and detached from the main body 12, the shades 15 with reflectors with different light distributions can be freely exchanged. can be provided.
