Embodiment FIGS. 1 to 4 show a first embodiment of the present invention. This fixture 1 consists of a plate-like locking piece 1a formed in a rectangular shape and a cylindrical suspension body 1b, and an instrument attachment portion 1c is provided at the lower end of the suspension body 1b. It is something.

The locking piece 1a has a rectangular shape as shown in FIG. 2, and the dimension d1 of one side thereof is at most two T-bars 2a.
The dimension w1 of the slit 2b of the WT bar 2 formed by
, and the dimension d2 of the other side is larger than at least the dimension w1 of the slit 2b, and the T-bar 2a
This is set smaller than the dimension w2 between the upright pieces 2c.

The suspension body 1b is fixed approximately at the center of the locking piece 1a perpendicularly to the locking piece 1a by caulking, welding, etc., and is suspended from the locking piece 1a. An instrument attachment portion 1c is provided which is formed by thread cutting or the like.

[0010] The fixture 1 configured as described above has a fixture 3 such as a guide light, an indicator light, or a human body detection sensor attached to the fixture mounting portion 1c of the hanging body 1b, and a locking piece 1a as shown in FIG. The locking piece 1a is inserted by aligning the longitudinal direction with the slit 2b of the WT bar 2 and rotating approximately 90 degrees.
is locked to the horizontal piece 2d of the WT bar 2, and the instrument 3
Attached to bar 2. Therefore, even after the ceiling material 4 has been installed, the fixture 3 can be easily installed at any position in the slit 2b of the WT bar 2 from below the ceiling without using screws or the like, resulting in good workability.

Furthermore, as shown in FIG. 4, in the portion of the WT bar 2 where the slits are perpendicular to each other, the locking pieces 1a can be inserted together and slid to lock.

FIG. 4 shows a second embodiment of the present invention, which differs from the first embodiment in the locking piece 1a, and the other features are the same as in the first embodiment. has been done.

[0013] The locking piece 1a is constructed by providing hanging pieces 1d at both ends in the longitudinal direction substantially parallel to the hanging member 1b in the first embodiment.

[0014] The fixture 1 constructed in this manner is similar to the first embodiment described above, in that the slit 2a of the WT bar 2 on the ceiling is
, and with the locking piece 1a inserted above the upright piece 2c of the T-bar 2a, rotate the fixture 1 approximately 90 degrees so that the hanging piece 1d is aligned with the outside of the upright piece 1c of the T-bar 2a. The device 3 is attached to the WT bar 2 by placing the locking piece 1a on the upper end of the upright piece 1c.

[0015] With such a configuration as well, the same effects as those of the first embodiment can be achieved, and the instrument 3 is
There is less risk of the item falling. Moreover, since the T-bar 2a disposed on the ceiling is always provided orthogonal to the emergency exit/exit, it is easy to determine the direction of the fixture 3 when the fixture 3 is a guide light or an indicator light.

FIG. 6 shows a third embodiment of the present invention, which differs from the first and second embodiments in that the locking piece 1
a, and the other structures are the same as those in the first and second embodiments.

In the first and second embodiments, the locking piece 1a is provided with a power supply connection terminal 1e on its upper surface.

[0018] With this configuration as well, the same effects as those of the first embodiment can be achieved, and the work of connecting the power supply lines can be facilitated.

FIG. 7 shows a fourth embodiment of the present invention, in which a horizontal rotation function is added to the instrument mounting portion 1c of the fixture 1 in the first embodiment.
The angle of the instrument 3 with respect to the fixture 1 can be set freely. Even with this configuration, the first
The same effect as in the embodiment is achieved.

FIG. 8 shows a fifth embodiment of the present invention. In the first embodiment, the locking piece 1 of the fixture 1
A through-hole 1f is provided in the hanging body 1b, and the instrument attachment part 1c is
is inserted into the power supply hole 3a of the instrument 3 and attached, and this through hole 1f is used as an insertion hole for the power supply line 5. Even with this configuration, the same effects as those of the first embodiment can be obtained, and since the device 3 does not require processing such as drilling, the device 3 can be attached more easily.

[0021] In each of the above-mentioned embodiments, screws were provided in the instrument attachment portion 1c of the hanging body 1b of the fixture 1, but the present invention is not limited to this. Some devices have a through hole in the device and are locked by inserting a pin etc. into the hole after insertion into the device, while others have a protrusion at the end and are locked by rotating the locking tool after insertion into the device. It can be anything.

[0022]

Effects of the Invention As described above, the fixture of the present invention has a plate-shaped locking piece and a hanging member fixed to the locking piece so as to hang down thereon. A device mounting portion is provided at the lower end of the hanging holder, and the locking piece is formed in a slit formed by two T bars of the WT bar installed on the ceiling so that it can be freely engaged and detached from below. Simply attach the fixture to the fixture mounting part of the fixture, insert this fixture into the slit from below the ceiling, rotate it, and lock it to the WT bar, and the fixture will be suspended from the WT bar, completing the installation. Therefore, even after the ceiling material has been installed, the fixture can be easily installed at any position in the WT bar slit from below the ceiling without using screws, making it easy to install, and the fixture can be removed in the same way. This can be done extremely easily from below the ceiling.
