Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a hanging structure for a lighting fixture when the lighting fixture is hung using a pair of hanging fittings.

[Background technology]

As shown in FIG. 1, when hanging a lighting fixture 2 by locking a pair of hanging brackets 1, 1 attached to the upper surface of the lighting fixture 2 to both ends of a hooking bracket 3 attached to the ceiling surface, conventional methods As shown in FIG.
The lower portions of both ends of the hanging fitting 1, which are used as the locking portions 4 for A bent part 11 is formed to prevent the hanging metal fitting 1 from falling off from the mounting metal fitting 10 when the width between the lower ends of the hanging metal fitting 1 becomes small. Therefore, since the hanging fitting 1 can freely rotate on the upper surface of the lighting fixture 2, the hanging fitting 1 must be held while being locked to the hanging fitting 3 attached to the ceiling surface. Moreover, as shown in FIG. 3, when an external force is applied and the lighting fixture 2 is pushed up, the hanging bracket 1 falls onto the lighting fixture 2 and comes off from the hooking bracket 3. There is a risk of it being stored away. Since the hanging fitting 1 itself is provided with a bent part 11 to prevent it from coming off, it is not possible to attach it to the lighting fixture 2 using a member cut and raised from the lighting fixture 2, and the mounting bracket as shown in the figure cannot be used. 10 is required separately.
In FIG. 1, 12 is a hook ceiling, and 13 is a sealing body.

[Purpose of invention]

The present invention was devised in view of these points, and its purpose is to facilitate the work of locking the hanging fitting to the hooking fitting, and to easily remove the hanging fitting from the hooking fitting. To provide a hanging structure for a lighting fixture that does not come off, and also allows the hanging metal fitting to be installed in a state where it is prevented from coming off by simply cutting and raising it from the lighting fixture. Provides a suspended structure.

[Disclosure of invention]

This invention has an engaging piece that engages with a mounting part provided on the top surface of the lighting fixture and an engagement piece that contacts the top surface of the lighting fixture at the bottom of both ends of each hanging fixture, whose center upper part serves as an engaging part for the hanging fixture. The device is characterized by the provision of contact pieces that make the hanging fittings self-supporting. The lower parts of both ends of the hanging metal fitting 1, which has a substantially Ω-shape and whose central upper part serves as a locking part 4 for the hooking metal fitting 3, are bent into a substantially U-shape, and the tip of the hanging metal fitting 1 is bent into a substantially U-shape. The L-shaped portion is used as the contact piece 6 so that the overall side surface shape is L-shaped. On the other hand, from the top plate of the lighting fixture 2, there is a rotating support part 8 into which the engaging piece 5 is inserted by cutting and raising it, and a retaining protrusion 9 for preventing the engaging piece 5 from coming off, where the edge of the engaging piece 5 comes into contact with the top plate. Let's set this. The hanging metal fitting 1 with the engagement pieces 5 at both ends inserted into the rotation support portions 8 can be hung on the lighting equipment 2 by the contact pieces 6 coming into contact with the upper surface of the lighting equipment 2. While making it self-supporting, the rotation range of the hanging fitting 1 is restricted. Here, as shown in FIG. 5, the pair of hanging metal fittings 1, 1 are arranged such that the range in which they can rotate is on the side of the other hanging metal fitting 1, and the pair of hanging metal fittings 1, 1 in a free-standing state are Width β between the locking parts 4 of the hanging fitting 1
is the width α between the pair of hooks 7 in the hook 3
Let's make it smaller.

When installing the hanging fittings 1, 1 by locking them to the hooking fitting 3, both the hanging fittings 1, 1 should be made independent, and one of the hanging fittings 1 should be attached to the hooking fitting 3.
Then, while bending this hanging metal fitting 1, the other hanging metal fitting 1 is locked to the hooking metal fitting 3. Due to the presence of the contact piece 6, the hanging metal fitting 1 does not fall over even with slight vibrations, so there is no need to hold the hanging metal fitting 1. Incidentally, each hanging metal fitting 1 is laid down at the time of packaging.

In this way, when the lighting fixture 2 is suspended, the hanging bracket 1 is pulled downward by the load of the lighting fixture 2, and the width between the lower ends of the hanging bracket 1 tends to become smaller. Since it is inserted from the outside, the hanging fitting 1 will not fall off. Conversely, when the lighting fixture 2 is pushed up by some external force, a compressive force acts on the hanging fitting 1 and the width between the lower ends of the hanging fitting 1 tends to widen, but this is due to the contact with the retaining protrusion 9. Since the hanging metal fitting 1 is prevented from coming off from the rotation support part 8 due to the contact, the hanging fitting 1 will not come off from the rotation support part 8.
Also, when pushed up in this way, the locking part 4 of the hanging metal fitting 1 lifts up from the hooking part 7 of the hanging metal fitting 3, but the hanging metal fitting 1 is independent and will not fall outward, and will not fall inward. Since the lighting fixture 2 has a spring elasticity that moves toward the lighting fixture 2, when the external force acting on the lighting fixture 2 is removed and it returns to its original state, the locking part 4 of the hanging fixture 1 is sure to re-engage with the hooking part 7 of the hanging fixture 3. .

Although FIGS. 6 and 7 show other embodiments of the hanging metal fitting 1, the same effects as those of the above-mentioned embodiments can also be obtained with those shown. By providing the lighting fixture 2 with a member to prevent the hanging fitting 1 from falling off, the hanging fitting 1 can be attached to the lighting fixture 2 by simply providing a cut-up member on the lighting fixture 2 without using the mounting fitting 10 or the like. It can be done.

[Effect of the invention]

In the case of this invention, as mentioned above, the work of attaching and locking the hanging fitting to the hooking fitting can be done easily, and even if the lighting equipment is pushed up, the hanging fitting is difficult to come off from the hooking fitting. It is something that has become familiar.
