Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a structure for attaching a lid to an inspection port of an equipment unit installed in a bathroom or the like.

[Background technology]

The equipment unit X installed in a bathroom or the like and having a washbasin bowl 6 etc. attached to the top is provided with an inspection port 2 for inspecting internal piping, etc. The lid 3 was attached by screwing screws 7 passed through both ends of the lid 3 into the equipment unit X, as shown in FIG.

At this time, bending pieces 9 are provided at both ends of the lid 3 for reinforcement in order to prevent the ends of the M3 from meandering in the front and back directions when the screws 7 are tightened. Therefore, the screw 7 is passed through this bent piece 9.

However, in this case, there is no problem if the lid 3 is flat as shown in Figure 1a, but if the surface of the equipment unit If the lid 3 has a curved shape that conforms to the above, when the screw 7 is tightened, the upper and lower ends of the central part of the lid 3 may be separated from the equipment unit X, and the adhesion may deteriorate.

That is, the screws 7.7 are passed through each M3 bent piece 9 so as to face diagonally inward, and as shown in FIG. Since this acts to flatten the bent piece 9, a force that tends to bend the lid 3 outward acts in the center of the lid 3 in the direction B as a reaction force that prevents this flattening. Therefore, there is a risk that the upper and lower ends of the central portion of the lid 3 may be separated from the equipment unit X, resulting in poor adhesion.

The stronger the screw 7 is tightened, the more this occurs.

[Purpose of invention]

The present invention was developed in view of the above points, and the object thereof is to provide a structure for attaching a lid to an inspection port, which allows the lid to be attached closely to a base having a convexly curved surface shape. It is.

[Disclosure of invention]

Therefore, in the structure for attaching a lid to an inspection port according to the present invention, the inspection port 2 is opened in the base 1 which has a convexly curved surface, and the lid 3, which is curved in a convex shape along the convexly curved surface of the base 1, is attached to the inspection port. At both ends of the lid 3, inclined pieces 8 and 8 extend in directions that are inclined to opposite sides toward the outside of the base body 1, and from the tips of the inclined pieces 8 and 8, respectively. The bent pieces 9, 9 extend in directions opposite to each other, and screws 4, 4 are attached to each inclined piece 8, 8 from the front side inwardly of the base body 1 in directions slanted in opposite directions. Through the screws 4, 4, the screws 4, 4 are attached to the receivers 5, with the inclined pieces 8, 8 of the lid 3 facing the outside of the receivers 5, 5, one end of which is attached to the inside of the base 1 at the peripheral edge on both sides of the inspection port 2. ，
5, and the tips of protruding pieces 13 and 13 provided at the tip of each bent piece 9 of the lid 3 to protrude inward of the base body 1 are attached to the peripheral edges on both sides of the inspection port 2. The lid 3 is brought into contact with the front side of the base 1, and the upper and lower portions of the central part of the lid 3 are brought into contact with the outer surface of the base 1 at the upper and lower edges of the inspection port 2. By doing so, the above purpose was made to be a distant relative.

The present invention will be explained in detail below using examples.

The base body 1 has a curved surface with a protruding side surface, and a washing bowl 6 is attached to the upper part of the base body 1 to form an equipment unit X, which is installed near a bathtub 12, for example, as shown in FIG.

In addition, an inspection port 2 is opened on the side surface of the base body 1, which is a convexly curved surface, and wooden frame receivers 5, 5 are attached to both sides of the back surface of the peripheral edge of the inspection port 2.

The lid 3 is formed into a curved shape that matches the convex shape of the side surface of the base body 1, and has an inclined piece 8, a bent piece 9 continuous with the inclined piece 8, and a protruding piece 13 extending from both ends thereof.

To attach this lid 3 to the inspection port 2, as shown in FIG.
4 are passed through each other so as to face obliquely outward, and the screws 4, 4 are screwed to the receivers 5, 5, so that the tip of the bent piece 9 is connected to the base 1.
This is done by bringing it into contact with the outer surface of the

At this time, when tightening the screw 4, the force acts in the C direction, so
A force acts on the lid 3 to deform the central portion in the direction D, and the upper and lower portions of the central portion of the lid 3 come into close contact with the outer surface of the peripheral edge of the inspection port 2.

Incidentally, attach the gasket 10 to the bent piece 9 of the lid 3 as shown in FIGS.
The waterproof property can be improved by allowing the base member 1 to come into contact with the outer surface of the base body 1.

In addition to the receiver 5 shown in Fig. 3, the receiver 5 and the lid 3 can be connected by using an angle-shaped metal fitting as shown in Fig. 5a and tightening the receiver 5 of the angle-shaped metal fitting with a nut 11. The base body 1 may be sandwiched between the bent piece 9, and the fifth
As shown in the figure, the receiver 5 may be fixed to the base 1 by using scissors as the receiver 5.

[Effect of idea]

As mentioned above, according to the present invention, when attaching the lid, which is curved in a convex shape along the convex curved surface of the base, to the outside of the inspection opening of the base body, which has a convex curved surface, with screws, the screws are attached to both ends of the lid. The slanted pieces extend outward from the base body in a direction that is slanted to opposite sides, and the bent pieces are respectively extended from the tip of each slanted piece in a direction that faces opposite to each other, and each slanted piece has a front side. Pass the screws inward toward the base in directions that are slanted to opposite sides of the base, and place the slanted pieces of the lid on the outside of the holder, which has one end attached to the inside of the base at the periphery on both sides of the inspection port. Then screw the screw into the holder, and insert the tips of the protruding pieces provided at the ends of each bent piece of the lid so as to protrude inward of the base from the front side of the base at the periphery on both sides of the inspection opening. At the same time, the upper and lower parts of the central part of the lid are brought into contact with the outer surface of the base at the upper and lower edges of the inspection port. Using the bent pieces at both ends of the lid that are in contact with the base as fulcrums, a force acts on the center of the lid to pull it inward toward the base, and this force causes the center of the lid to move toward the outside of the base. Even if the base body has a convex curved shape and the lid is curved to follow the convex curved shape, the lid can be brought into close contact with the front surface of the base body at the periphery of the inspection port. There is no risk of the gap being exposed to the outside or the waterproofness being reduced.
