Description

[Detailed explanation of the idea] 〔Technical field〕 This invention relates to lighting equipment.

[Background technology]

As shown in FIG. 1, a pair of hooks 2,
2' to be hung on the ceiling hangers 3, 3', and a ceiling cap 4 to be hooked on the ceiling body 5 (electrical connection), thereby bringing the appliance almost in close contact with the ceiling surface. There is something to install.

However, since the height of the hooks 2 and 2' cannot be made very large (to bring them as close to the ceiling as possible), it is difficult to put one's hand into the gap H as shown in Figure 2. Because of this, it had a weak back, and as shown in Figure 2, it had the disadvantage that it was difficult to hook onto a hanger because it bent at the fingertips when grasped.

In addition, for purposes such as replacing lamps or cleaning appliances, the shade 6 is hooked on one side of the appliance body 1 and rotated, as shown in Figure 3. It would be convenient to rotate the shade horizontally and hook its tip onto the end of the instrument body 1, but if the shade 6 is only hooked on one side, the weight will be on one side, so the hanging ceiling hanger 3° 3' The device body 1 is attached using the claw as a fulcrum.
There is a risk that the other side of the appliance body 1 may rotate and hit the ceiling.

Therefore, there is a risk of damaging the ceiling surface, and at the same time,
When locking the shade 6 to the appliance main body 1, it was difficult to lock the shade 6 because the shade locking portion came into close contact with the ceiling surface.

Note that 7 is a lamp. [Purpose of the invention] The object of this invention is to provide a ceiling-hanging type lighting fixture in which a light distribution control member such as a shade can be easily attached and detached from the fixture body.

[Disclosure of invention]

The lighting equipment of this invention includes a main body having a ceiling cap that is hung on a ceiling ceiling body, a pair of ceiling hangers provided on both sides of the ceiling body, and a pair of ceiling hangers facing each other and having a ceiling cap attached to the top of each of the ceiling hangers. A pair of hooks A hook for the ceiling hanger has a pair of hooks having both legs attached to the upper surface of the instrument body, and an end portion of the instrument body in the alignment direction of the pair of hooks. The light distribution control member is rotatably attached around orthogonal horizontal axes.

An embodiment of this invention is shown in FIGS. 4 to 6.

That is, 9 is a shade, and the instrument body 8 has a central hole 10.
A cord 11 is pulled out and a sealing cap 12 is provided at the tip of the cord.

In addition, a mounting bracket 13 is provided on the upper surface of the instrument main body 8, and both legs 16 of the Ω-shaped hooks 15, 15' formed of steel wire are pivotally supported.
A torsion coil spring 17 (
Figure 6) is provided.

A locking fitting 18 is attached to the end of the pair of hooking bodies 15 and 15' on the side of the hooking body 15 where the spring 17 is not provided in the arrangement direction of the pair of hooking bodies 15 and 15' of the instrument main body 8, and a hooking fitting 20 is attached to the upper opening edge of the shade 9 correspondingly.
A rotation locking tool 21 is rotatably provided on the opposite side of the shade 9 from the hooking tool 20 side with a screw 22.

22 is a positioning screw in a locked state, and 23 is an engagement recess.

When installing this lighting fixture on the ceiling, hook 15.15
Support part of ' with your fingertips and hang it on hangers 3 and 3'.

At this time, since the hooks 15, 15' are relatively rigid, they can be easily hooked onto the hangers 3, 3' by simply holding the bases of the hooks 15, 15'.

Then, the hook ceiling cap 12 is hooked on the hook ceiling body 5.

Also, when replacing the lamp, etc., move the rotation locking tool 21 toward the arrow a side.
Rotate 80 degrees to remove it from the instrument body 8, rotate the shade 9 to a vertical position, and remove the hook 20 from the locking tool 21.

When installing, perform this operation in reverse.

At this time, since the hook 20 is located in the direction in which the hooks 15 and 15' are lined up, the instrument main body 8 does not rotate, and the shade attaching operation is facilitated.

In addition, since the torsion coil spring 17 biases the hook 15' in the direction of pressing the hanger 3', an unexpected external force is applied to the instrument when attaching or removing the shade, causing the instrument body 8 to tilt and the hook 15' to move upward. Even if it floats, the hook 15' will not come off the hanger 3' and there is no risk of it falling, and the equipment can be easily attached.

Note that the hook body only needs to have at least enough rigidity to have stiffness, and if it has spring properties, it may also function as a torsion coil spring. may be done.

On the other hand, if torsion coil springs are provided on both of the hooks 15 and 15', unexpected external forces can be coped with.

Furthermore, the shade is not limited to this, and may be a light distribution control member such as a glove or a transparent cover.

[Effect of idea]

According to this invention, the following effects are achieved.

(a) Each of the pair of hooks has a hook part at the top for the pair of hook ceiling hangers, and the cost is low because it is extremely simple, with both legs of each hook attached to the top surface of the device body. can be implemented.

(b) On the other hand, there is a risk that the main body of the instrument may rotate around the engagement portion between the top of the hook and the ceiling hanger.

That is, when the light distribution control member is hanging from the appliance body in a single-hung manner, there is a risk that the appliance body may tilt due to an unbalanced center of gravity (conventional example).

However, according to this invention, a light distribution control member is configured to be rotatable about an axis in a lateral direction perpendicular to the arrangement direction at the end of the pair of hooks in the arrangement direction in the main body of the device. This prevents the instrument body from tilting despite the unbalanced center of gravity.

Therefore, it is possible to easily attach and detach the light distribution control member to and from the instrument body.
