図１～図８に、本発明の床下収納庫又は点検口用の蓋体の一実施例を示す。
この床下収納庫又は点検口用の蓋体１は、床Ｆに設けた床下収納庫又は点検口の開口部分を塞ぐために用いられるもので、表側部材２と裏側部材３とを、蓋枠４を介して、一体化してなり、蓋枠４の下端部に第１の係合部４１を設けるとともに、裏側部材３の外周部に、第１の係合部４１と係合する第２の係合部３１を設けてなるものである。 1 to 8 show an embodiment of the lid for an underfloor storage or inspection port of the present invention.
This under-floor storage or inspection door lid 1 is used to close the opening of the under-floor storage or inspection port provided on the floor F. A first engaging part 41 is provided at the lower end of the lid frame 4, and a second engaging part 41 is provided on the outer periphery of the back side member 3. A section 31 is provided.

ここで、裏側部材３には、ポリプロピレン樹脂等のポリオレフィン樹脂、ＡＢＳ樹脂、塩化ビニル樹脂等の合成樹脂材料で形成されてなる、上面部３Ａと、下方を膨出させた下面部３Ｂと、上面部３Ａと下面部３Ｂとを合わせることで形成される空間内に配置されてなる格子構造（又はハニカム構造）の補強用リブ部（図示省略）とを備え、上面部３Ａ、下面部３Ｂ及び補強用リブ部が、一体化されてなるものを好適に用いることができる。
そして、補強用リブ部のリブ間に、発泡樹脂、グラスウール、ロックウール等の断熱材を充填するようにすることもできる。 Here, the back side member 3 includes an upper surface part 3A formed of a synthetic resin material such as polyolefin resin such as polypropylene resin, ABS resin, vinyl chloride resin, etc., a lower surface part 3B having a bulged lower part, and an upper surface. It includes a reinforcing rib part (not shown) of a lattice structure (or honeycomb structure) arranged in a space formed by combining the upper part 3A and the lower part 3B, and the upper part 3A, the lower part 3B and the reinforcing rib part A structure in which the rib portion is integrated can be suitably used.
Further, a heat insulating material such as foamed resin, glass wool, rock wool, etc. may be filled between the ribs of the reinforcing rib portion.

裏側部材３は、従来の床下収納庫又は点検口用の蓋体と同様、例えば、床Ｆの材料と同じ材料からなる表側部材２と組み合わせ、蓋枠４に加え、裏側部材３の裏面側からねじ等の締結手段（図示省略）を用いて組み立てることで、床面（床材Ｆ）に形成した開口部の枠部材５内に嵌め込んで使用する蓋体１とすることができる。 The back side member 3 is similar to a conventional cover for an underfloor storage or an inspection port, for example, in combination with a front side member 2 made of the same material as the floor F, and in addition to the cover frame 4, from the back side of the back side member 3. By assembling using fastening means (not shown) such as screws, the lid 1 can be used by being fitted into the frame member 5 of the opening formed in the floor surface (floor material F).

この場合において、本実施例においては、第１の係合部４１が、爪状の突起からなり、第２の係合部３１が、第１の係合部４１の爪状の突起が係合する窪みからなるように、より具体的には、内向きの爪状の突起からなる第１の係合部４１が、裏側部材３の上面部３Ａの外周部の下方に形成された窪み（裏側部材３の下面部３Ｂの後退部）からなる第２の係合部３１に係合するようにしている。 In this case, in this embodiment, the first engaging portion 41 is formed of a claw-like projection, and the second engaging portion 31 is formed of a claw-like projection of the first engaging portion 41. More specifically, the first engaging portion 41 consisting of an inward claw-like protrusion is formed in a recess formed below the outer periphery of the upper surface portion 3A of the back side member 3. He is trying to engage with a second engaging portion 31 consisting of a retracted portion of the lower surface portion 3B of the member 3.

裏側部材３の下面部３Ｂは、外周部に、第２の係合部３１を構成する窪み（裏側部材３の下面部３Ｂの後退部）及び第１の係合部４１を外周側から覆う、下から上に向けて立ち上がる起立片３２を形成するようにしている。 The lower surface part 3B of the back side member 3 covers the recess (recessed part of the lower surface part 3B of the back side member 3) constituting the second engaging part 31 and the first engaging part 41 from the outer peripheral side. An upright piece 32 is formed that rises from the bottom to the top.

ここで、第１の係合部４１及び第２の係合部３１の形状や形成位置や方向は、本実施例のものに限定されず、任意の係合構造を採用することができ、例えば、外向きの爪状の突起からなる第１の係合部４１が、裏側部材３の起立片３２の内周面に形成された窪みからなる第２の係合部３１に係合するようにしたり、第２の係合部３１を爪状の突起で、第１の係合部４１をこの爪状の突起が係合する窪みで、それぞれ構成するようにしたりすることができる。 Here, the shape, formation position, and direction of the first engaging part 41 and the second engaging part 31 are not limited to those of this embodiment, and any engaging structure can be adopted, for example. , the first engaging portion 41 consisting of an outward claw-shaped protrusion engages with the second engaging portion 31 consisting of a recess formed in the inner circumferential surface of the upright piece 32 of the back side member 3. Alternatively, the second engaging portion 31 may be configured as a claw-like protrusion, and the first engaging portion 41 may be configured as a recess into which the claw-like protrusion engages.

第１の係合部４１と第２の係合部３１を係合することにより、表側部材２を蓋枠４の鍔部４２で押さえ、裏側部材３との間で挟み込むようにした状態で、蓋枠４を裏側部材３に固定することができるが、さらに、必要に応じて、裏側部材３と蓋枠４をねじ６を用いて固定することができる。 By engaging the first engaging part 41 and the second engaging part 31, the front side member 2 is held down by the flange part 42 of the lid frame 4, and in a state where it is sandwiched between the back side member 3, The lid frame 4 can be fixed to the back side member 3, and if necessary, the back side member 3 and the lid frame 4 can be fixed using screws 6.

裏側部材３と蓋枠４をねじ６を用いて固定する場合、裏側部材３側からねじ込んだねじ６のねじ面が、蓋枠４の下端部に半掛けされてなるようにすることができる。
裏側部材３には、上面部３Ａ及び下面部３Ｂに、ねじ６の締め込み過ぎによるねじの空転を防止するためのねじ穴３３Ａ、３３Ｂを形成するようにする。
これにより、蓋枠４にねじ穴を形成しない分だけ蓋枠４の厚みを薄くすることが可能となるため、軽量化やデザイン性を向上することができ、軽量な床下収納庫又は点検口用の蓋体１を提供することができる。 When fixing the back side member 3 and the lid frame 4 using screws 6, the threaded surface of the screw 6 screwed in from the back side member 3 side can be half-hung on the lower end of the lid frame 4.
In the back side member 3, screw holes 33A and 33B are formed in the upper surface part 3A and the lower surface part 3B to prevent the screws 6 from idling due to over-tightening.
This makes it possible to reduce the thickness of the lid frame 4 by not forming a screw hole in the lid frame 4, making it possible to reduce weight and improve design. The lid body 1 can be provided.

また、裏側部材３の下面部３Ｂの裏面に、パッキン装着部３４を周溝状に形成する。
このパッキン装着部３４は、直線部と裏側部材３の角部に位置するコーナ部とからなり、パッキン装着部３４のパッキン３５を装着する装着面を、内周側と外周側との高さを違えた傾斜面に形成するようにしている。
ここで、傾斜面に形成する箇所は、少なくともコーナ部（本実施例においては、直線部とコーナ部とからなるパッキン装着部３４の全部。直線部の傾斜面をそのままコーナ部まで延長し、アール形状にしたり、角を落とした形状にしたりするようにしている。なお、直線部は、水平面に形成することもできる。）とする。
また、傾斜面は、本実施例のように、下方内向きの傾斜面に形成するほか、下方外向きの傾斜面に形成することもできる。
そして、パッキン装着部３４には、断面形状が略矩形をしたパッキン３５を、直線部からコーナ部にかけて連続して貼着するようにする。
このように、パッキン装着部３４の装着面を傾斜面に形成することにより、周溝状に形成したパッキン装着部のコーナ部における、パッキン装着部に装着したパッキン３５の内周側と外周側の伸縮差を少なくすることができ、コーナ部におけるパッキン３５の撚れや皺の発生を防止し、パッキン３５の装着性及び気密性を向上することができる。 Further, a packing mounting portion 34 is formed in the shape of a circumferential groove on the back surface of the lower surface portion 3B of the back side member 3.
This packing mounting part 34 consists of a straight part and a corner part located at a corner of the back side member 3, and the mounting surface of the packing mounting part 34 on which the packing 35 is mounted has a height between the inner circumferential side and the outer circumferential side. They are formed on different slopes.
Here, the part formed on the slope is at least the corner part (in this embodiment, the entire packing mounting part 34 consisting of a straight part and a corner part.The slope of the straight part is extended as it is to the corner part, and (Note that the straight portion can also be formed on a horizontal surface.)
Further, the inclined surface may be formed as a downwardly inwardly inclined surface as in this embodiment, or may be formed as a downwardly outwardly inclined surface.
A packing 35 having a substantially rectangular cross section is continuously attached to the packing mounting portion 34 from the straight line portion to the corner portion.
In this way, by forming the mounting surface of the packing mounting portion 34 into an inclined surface, the inner and outer circumferential sides of the packing 35 mounted on the packing mounting portion at the corner portions of the packing mounting portion formed in the shape of a circumferential groove are formed. It is possible to reduce the difference in expansion and contraction, prevent the packing 35 from twisting or wrinkling at the corner portions, and improve the fitability and airtightness of the packing 35.
