Description

[Detailed Description of the Invention] The present invention relates to a ceiling inspection device in a bus unit.

Generally, an inspection port provided in the ceiling of this type of bath unit is constructed such that a lid 14 is placed and suspended above the inspection port 13, as shown in FIG.

However, since the lid 14 is simply placed and suspended, the lid 14 moves greatly due to wind pressure, especially when the door of the bathroom is closed, causing unpleasant noises caused by collisions between the lids. At the same time, the lid body 1
4, which was thin and lightweight, had problems such as being blown off and coming off.

Therefore, one method that is generally considered is to fix the lid body 14 to the ceiling with screws, but with such a configuration, it must be removed using a tool such as a screwdriver every time inspection is performed, and this work is troublesome and This has problems such as the screw head being exposed and the appearance being impaired.

With the above points in mind, the present invention aims to prevent the lid from rattling due to wind pressure and to allow the lid to be easily removed without damaging the appearance.

In order to achieve the above object, the present invention provides an inspection hole having a substantially circular planar shape in a ceiling plate, and a cover body having a similar shape that is somewhat smaller than the inspection hole is fitted into this inspection hole.
The inspection port is provided with a pair of support pins that protrude inward from the periphery, and the lid body is provided with an upright portion on the periphery, and the upright portion has a substantially L-shaped notch on the side surface that engages with the support pin. This is a ceiling inspection device for a bath unit with holes.

According to this configuration, the lid is fixed by the engagement of the L-shaped groove and the pin, so the lid does not come off due to the wind pressure of the door. Since no screws are required, the fixing work is easy, and the heads of screws and the like are not exposed, giving it a good appearance.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In the figure, 1 is a bath unit main body, a washing area unit 2 having a bathtub part 2a and a washing area 2b,
It is composed of a wall material 3 and a ceiling board 4.
An inspection hole 7 having a substantially circular planar shape is bored in the ceiling plate 4 for inspecting the lighting unit 5 and the ventilation fan 6, and this inspection hole 7 has an upright piece 7a on the periphery.
Furthermore, a support pin 8 that projects inward of the inspection port 7 is fixed to the upright piece 7a. The inspection port 7 is provided with a lid 9 having a similar shape that is somewhat smaller than the inspection port 7.
is fitted, and the peripheral edge of the lid body 9 has a standing portion 9a.
The upright portion 9a is provided with a cutout hole 10 having a substantially L-shaped side surface that engages with the support pin 8.
11 is a sealing material such as a sponge, and 12 is a door.

In the above configuration, the lid 9 of the inspection port 7 is fixed by the engagement between the support pin 8 and the L-shaped cutout hole 10, so the lid 9 does not move due to wind pressure when the door is closed. Moreover, the removal of the lid body 9 is also
Since it is only necessary to engage the notch hole 10 with the support pin 8 protruding from the periphery of the inspection port 7 and horizontally rotate the cover body 9 clockwise, the operation is extremely simple and the appearance is also good. .

According to the present invention, the lid of the ceiling inspection port is fixed by the engagement of the support pin and the L-shaped notch, so it does not move or come off due to wind pressure when the door is opened and closed. Furthermore, since a sealing material is interposed between the ceiling inspection port and the lid, the sealing material can reliably prevent the lid from moving and maintain airtightness between the two. This has the effect of creating a structure that prevents moisture within the bath unit from leaking into the ceiling.
