Hereinafter, embodiments of the lid for the underfloor storage or inspection port of the present invention will be described with reference to the drawings.

1 to 8 show an embodiment of a lid for an underfloor storage or inspection port of the present invention.
The lid 1 for the underfloor storage or the inspection port is used to close the opening portion of the underfloor storage or the inspection port provided on the floor F, and the front side member 2 and the back side member 3 are attached to the lid frame 4. A second engaging portion 41 is provided at the lower end portion of the lid frame 4 and is engaged with the first engaging portion 41 at the outer peripheral portion of the back side member 3. A unit 31 is provided.

Here, the back side member 3 has an upper surface portion 3A formed of a polyolefin resin such as polypropylene resin, an ABS resin, a synthetic resin material such as vinyl chloride resin, a lower surface portion 3B that bulges downward, and an upper surface portion. A rib portion (not shown) for reinforcing a lattice structure (or honeycomb structure) formed in a space formed by combining the portion 3A and the lower surface portion 3B is provided, and the upper surface portion 3A, the lower surface portion 3B, and the reinforcing portion are provided. Those in which the rib portions are integrated can be preferably used.
Then, a heat insulating material such as foamed resin, glass wool, or rock wool can be filled between the ribs of the reinforcing rib portion.

The back side member 3 is the same as the conventional lid for the underfloor storage or the inspection port, for example, in combination with the front side member 2 made of the same material as the floor F, and in addition to the lid frame 4, from the back side of the back side member 3. By assembling using a fastening means (not shown) such as a screw, the lid 1 can be used by being fitted into the frame member 5 of the opening formed on the floor surface (floor material F).

In this case, in this embodiment, the first engaging portion 41 is composed of a claw-shaped protrusion, and the second engaging portion 31 is engaged with the claw-shaped protrusion of the first engaging portion 41. More specifically, the first engaging portion 41 formed of an inwardly claw-shaped protrusion is formed below the outer peripheral portion of the upper surface portion 3A of the back side member 3 (back side). It is adapted to engage with a second engaging portion 31 composed of a retracted portion of the lower surface portion 3B of the member 3.

The lower surface portion 3B of the back side member 3 covers the recess (retracting portion of the lower surface portion 3B of the back side member 3) forming the second engaging portion 31 and the first engaging portion 41 from the outer peripheral side on the outer peripheral portion. The standing pieces 32 that stand up from the bottom to the top are formed.

Here, the shapes, forming positions, and directions of the first engaging portion 41 and the second engaging portion 31 are not limited to those of the present embodiment, and any engaging structure can be adopted, for example. The first engaging portion 41 formed of an outwardly claw-shaped protrusion engages with the second engaging portion 31 formed of a recess formed on the inner peripheral surface of the upright piece 32 of the back side member 3. Alternatively, the second engaging portion 31 may be formed by a claw-shaped protrusion, and the first engaging portion 41 may be formed by a recess in which the claw-shaped protrusion is engaged.

By engaging the first engaging portion 41 and the second engaging portion 31, the front side member 2 is pressed by the flange portion 42 of the lid frame 4 and sandwiched between the back side member 3 and the lid frame 4. The lid frame 4 can be fixed to the back side member 3, but further, the back side member 3 and the lid frame 4 can be fixed by using screws 6 if necessary.

When the back side member 3 and the lid frame 4 are fixed by using the screw 6, the screw surface of the screw 6 screwed from the back side member 3 side can be half-hung on the lower end portion of the lid frame 4.
On the back side member 3, screw holes 33A and 33B are formed in the upper surface portion 3A and the lower surface portion 3B to prevent the screws from slipping due to overtightening of the screws 6.
As a result, the thickness of the lid frame 4 can be reduced by the amount that the screw holes are not formed in the lid frame 4, so that the weight and design can be improved, and it is used for a lightweight underfloor storage or inspection port. Lid body 1 can be provided.

Further, a packing mounting portion 34 is formed in a circumferential groove shape on the back surface of the lower surface portion 3B of the back side member 3.
The packing mounting portion 34 includes a straight portion and a corner portion located at a corner of the back side member 3, and the mounting surface of the packing mounting portion 34 on which the packing 35 is mounted has heights of the inner peripheral side and the outer peripheral side. It is designed to be formed on a different inclined surface.
Here, the portion formed on the inclined surface is at least the corner portion (in this embodiment, the entire packing mounting portion 34 including the straight portion and the corner portion. The inclined surface of the straight portion is extended to the corner portion as it is, and is rounded. The shape is made to have a shape or the shape has rounded corners. The straight part can also be formed on a horizontal plane.)
Further, the inclined surface may be formed on an inclined surface facing downward and inward as in the present embodiment, or may be formed on an inclined surface facing downward and outward.
Then, the packing 35 having a substantially rectangular cross-sectional shape is continuously attached to the packing mounting portion 34 from the straight portion to the corner portion.
By forming the mounting surface of the packing mounting portion 34 on an inclined surface in this way, the inner peripheral side and the outer peripheral side of the packing 35 mounted on the packing mounting portion in the corner portion of the packing mounting portion formed in the shape of a peripheral groove. It is possible to reduce the difference in expansion and contraction, prevent twisting and wrinkling of the packing 35 at the corners, and improve the wearability and airtightness of the packing 35.

According to the lid 1 for the underfloor storage or the inspection port, the first engaging portion 41 is provided at the lower end portion of the lid frame 4, and the first engaging portion 41 is provided at the outer peripheral portion of the back side member 3. By providing a second engaging portion 31 to be engaged, the number of screws for fastening the lid frame 4 and the back side member 3 can be reduced (or the use of screws can be eliminated), and at the time of assembly. It is possible to provide an underfloor storage or a lid 1 for an inspection port which can improve workability and is easy to handle.
