[0013]

[Problems to be Solved by the Invention] In public facilities such as the above-mentioned urban public toilets, it is almost impossible to remove equipment and remove it, kick it off with your feet, hit it with a blunt instrument, or set it on fire. Suffer mischief. The ceiling inspection lid is no exception, and is often opened or removed unnecessarily.

It is an object of the present invention to provide a ceiling inspection port structure that is less susceptible to such mischief.

[0015]

SUMMARY OF THE INVENTION A ceiling inspection port structure according to the present invention relates to an inspection opening provided on a ceiling surface, a lid attached to the opening, and the lid attached to an edge of the opening. In the ceiling inspection port structure including a locking member for stopping, the ceiling surface includes a high ceiling surface and a low ceiling surface having different heights, and a vertical surface between the two, and the opening includes Is provided from the vertical surface to the low ceiling surface, the lid is horizontally removable from a portion of the opening at the vertical surface , and the lighting device is mounted on the ceiling surface so as to cover the vertical surface. Removably attached to
The lower end portion of the lighting fixture is inserted when the lid is inserted.
It is characterized by being located in a passage area .

[0016]

[Action] In the ceiling inspection port structure of the present invention,
After removing the lighting fixture, remove the lid by sliding it horizontally. That is, the lid cannot be removed unless the lighting fixture is removed. For this reason, even if the user attempts to open the lid by mischief, the lid is not opened immediately, so that damage and theft of the inspection port and the lid due to mischief can be prevented.

[0017]

Embodiments will be described below with reference to the drawings. First (sectional view taken along line I-I of FIG. 2) shows a longitudinal sectional view showing <br/> ceiling access door structure according to the embodiment of the present invention, the second
The figure is a horizontal sectional view along the line II-II in FIG. 1, and FIG.
FIG. 4 is a perspective view of a portion III in FIG. 4, and FIG. 4 is an enlarged view of a portion IV in FIG.

This embodiment relates to an embodiment applied to the inspection port of the ceiling surface 26 of the above-mentioned urban public toilet. In this embodiment, the above-mentioned ceiling surface 26 is a low ceiling surface.
In addition, the ceiling surface other than the luggage space 14 has a high ceiling surface 30 higher than the low ceiling surface 26. 31
Is a side wall surrounding the luggage space 14, and 32 is an outer wall, and the outer wall 32 is provided with an exhaust port 33. 34 is a roof of an urban public toilet.

The ceiling surface (low ceiling surface) 26 is provided with an opening 35 for inspecting facilities behind the ceiling such as the exhaust fan 25 and the like, and a lid 36 is attached to the opening 35.

As shown in FIGS. 2 and 4, a latch 37 is fixed to the edge of the lid 36.
Is hooked on the upper end of the side wall 31 to lock the lid 36 at the opening 35 portion.

An upper surface 38 is provided between the high ceiling surface 30 and the low ceiling surface 26, and the opening 35 is
8 to the lower part.

A lighting device 40 is provided on the vertical surface 38. In this embodiment, the lighting fixture 40 is a case 41
When provided with a root bars 42 mounted on the casing 41, and a light tube 43 such as a fluorescent lamp. Lou bar 42 has a spring 44, the louvers over 42 cases 4 by inserting the spring 44 in the ceiling through a slit 45
It is fixed to 1.

[0023] As shown in FIG. 1, this rule bar 42 extends to below the case 41, Lou bar 42
Is substantially flush with the bottom surface of the lid 36.

[0024] The thus constituted ceiling access door structure in <br/> Oite can not be removed the lid 36 unless remove the root bar 42. That is, even if the cover 36 is lifted upward, the cover 36 hits the exhaust fan 25, so that the cover 36 cannot be tilted greatly, and therefore, the cover 36 cannot be pulled out from the opening 35.

[0025] Removing the route bar 42, the hook fittings 37 to lift the lid 36 on the slightly is disengaged from the upper end of the side wall 31 can be pulled by sliding the lid 36 to the right in Figure 1. Therefore, maintenance workers familiar with the inspection opening structure, opening the lid 36 and remove the root bar 42, but the inspection of ceiling facilities such as an exhaust fan 25 can be easily performed, such a structure A general user who does not know cannot open the lid 36. Therefore, the lid 36 is inadvertently opened and the facilities behind the ceiling are damaged,
Alternatively, mischief such as removing the lid 36 is prevented.

In the above embodiment, the latch 37 has a downward U-shaped cross section, and is fixed to the lid 36 by screws, bolts, welding, or the like. However, the present invention is not limited to this. For example, as shown in FIG. 5, a locking metal member 50 having a laterally U-shaped cross section is fixed to the upper end of the side wall 31 and a horizontal projection 51 provided on the outer periphery of the lid 36 is provided. May be swallowed by the locking hardware 50. The fifth
With the structure shown in the figure, the lid 36 cannot be lifted,
Mischief of removing the lid 36 can be reliably prevented.

In the above embodiment, the opening 35 has a semicircular shape, but the present invention is not limited to this, and may have a trapezoidal shape as shown in FIG. 6, for example. In the case of a semicircular or trapezoidal opening, the lid 36 attached to the semicircular or trapezoidal shape naturally has a semicircular or trapezoidal shape.

[0028]

As described above, according to the ceiling inspection port structure of the present invention, the lid of the inspection opening cannot be removed unless the lighting fixture is removed. Therefore, obstacles such as removing the lid and taking it away, or mischievous facilities behind the ceiling can be reliably prevented.
