Description

この発明は、フロアパネルの塞ぎ板に関するもので、更に詳細には、例えば、コンピュータシステムの端末機器や通信機器等の設備を載置するフリーアクセスフロアパネルに形成された配線取出開口を塞ぐフロアパネルの塞ぎ板に関するものである。   The present invention relates to a floor panel closing plate, and more particularly, for example, a floor panel that closes a wiring extraction opening formed in a free access floor panel on which equipment such as a terminal device or a communication device of a computer system is placed. It is related to the closing plate.

一般に、基礎となる床と増設した床の間で自由に配線できるようにした二重床を構成するフリーアクセスフロアパネルにおいては、配線取出開口を塞ぐ塞ぎ板に配線取出用の切欠きを設けて、配線の一部を取り出せるようにしている。   In general, in a free access floor panel that constitutes a double floor that allows free wiring between the base floor and the additional floor, a notch for wiring extraction is provided on the closing plate that closes the wiring extraction opening. I can take out a part of.

この種の塞ぎ板においては、配線取出用の切欠きを形成した後に、レイアウトの変更に伴う配線の変更等によって切欠きを塞ぐ必要がある。   In this type of closing plate, it is necessary to close the notch by changing the wiring accompanying a layout change after forming the notch for wiring extraction.

そのため、従来では、配線取出用の切欠きを切り離し可能に形成し、切り離した部材を配線取出用の切欠きの塞ぎ部材に供せるようにしたものが知られている（例えば、特許文献１，２参照）。   For this reason, conventionally, it is known that a notch for wiring extraction is formed so as to be separable, and the separated member can be used as a closing member for the notch for wiring extraction (for example, Patent Document 1, Patent Document 1). 2).

特許文献１，２に記載のものは、いずれも配線取出開口を塞ぐ塞ぎ板に設けられた切欠きと、この切欠きを閉塞可能な蓋片とを連結した状態で一体成形した構造であり、蓋片を塞ぎ板から切り離した後に、蓋片に設けた軸や突出部等を切欠きに設けた孔や凹部等に嵌合あるいは係合させて、切欠きを開放して配線を取り出すか、あるいは、不要の切欠きを塞いでいる。   The ones described in Patent Documents 1 and 2 are structures that are integrally molded in a state in which a notch provided in a closing plate that closes the wiring extraction opening and a lid piece that can close the notch are connected. After separating the lid piece from the closing plate, the shaft or protrusion provided on the lid piece is fitted or engaged with the hole or recess provided in the notch, the notch is opened, or the wiring is taken out, Or the unnecessary notch is closed.

このように構成されるこの種の塞ぎ板は、フロアパネルに設けられた配線取出開口を塞ぐため、機械的強度や耐衝撃性を有する必要があり、また、成形加工が容易であることを考慮して、合成樹脂の射出成形によって一体成形されている。   This type of closing plate configured in this way needs to have mechanical strength and impact resistance in order to close the wiring extraction opening provided in the floor panel, and considers that the forming process is easy. And it is integrally molded by injection molding of synthetic resin.

しかしながら、特許文献１，２に記載のものは、いずれも使用に際して、蓋片を塞ぎ板から切り離して、再度、蓋片に設けた軸や突出部等を切欠きに設けた孔や凹部等に嵌合あるいは係合させて使用するため、配線の取り出しや不要な切欠きを閉じる配線作業に手間を要する。また、同時に複数箇所の配線作業を行う場合には、塞ぎ板から切り離された蓋片は、直ちに切欠きに取り付けないと紛失する懸念がある。   However, the ones described in Patent Documents 1 and 2 are, in use, separated from the cover plate from the cover plate, and again into the hole or recess provided in the notch with the shaft or protrusion provided on the cover piece. Since it is used after being fitted or engaged, it takes time and labor to take out the wiring and close the unnecessary notches. Further, when performing wiring work at a plurality of locations at the same time, there is a concern that the lid piece cut off from the closing plate may be lost unless it is immediately attached to the notch.

また、蓋片と塞ぎ板に設けられる、互いに嵌合又は係合可能な突出部と凹部等は、蓋片と塞ぎ板を一体成形する場合は、突出部と凹部等とを別の位置に設ける必要があるため、射出成形に用いられる金型に上記突出部と凹部等の形成部を別の箇所に設ける必要がある。したがって、金型が複雑になる上、生産コストが嵩む懸念がある。   In addition, the protrusions and recesses provided on the lid piece and the closing plate that can be fitted or engaged with each other are provided at different positions when the lid piece and the closing plate are integrally formed. Since it is necessary, it is necessary to provide the above-mentioned projecting part and the forming part such as the concave part in another place on the mold used for injection molding.

なお、切欠き１１側に位置する補助補強部２５の端部は、切欠き１１の開放側に向かって円弧状に形成されている（図５参照）。このように、補助補強部２５の端部を、切欠き１１の開放側に向かって円弧状に形成することにより、配線取出開口４に塞ぎ板１０を取り付ける際や、取外しする際に、配線取出開口４に補強部２０が干渉するのを防止することができるので、塞ぎ板１０の取り付け、取り外しを容易にすることができる。   In addition, the edge part of the auxiliary reinforcement part 25 located in the notch 11 side is formed in circular arc shape toward the open | release side of the notch 11 (refer FIG. 5). In this way, the end of the auxiliary reinforcing portion 25 is formed in an arc shape toward the opening side of the notch 11, so that when the closing plate 10 is attached to or removed from the wiring extraction opening 4, the wiring extraction is performed. Since it can prevent that the reinforcement part 20 interferes with the opening 4, attachment and removal of the closing board 10 can be made easy.

上記のように構成される補強部２０によれば、塞ぎ板１０に最も応力が集中する部位に強度をもたせることができる。すなわち、塞ぎ板１０における切欠き１１を設けた箇所の周囲に補強部２０を設けることによって塞ぎ板１０に強度をもたせることができる。また、補強部２０を構成する各リブ、すなわち、第１ないし第３の直状リブ２１，２２，２３、直状リブ２６及び補助直状リブ２７の肉厚を同一にすることで、塞ぎ板１０を射出成形によって作製した場合、平板部１３の表面に凹み（シンクマーク）が生じるのを防止することができる。   According to the reinforcing portion 20 configured as described above, it is possible to give strength to a portion where stress is most concentrated on the closing plate 10. That is, by providing the reinforcing portion 20 around the portion where the notch 11 is provided in the closing plate 10, the closing plate 10 can be provided with strength. Further, by making the thicknesses of the ribs constituting the reinforcing portion 20, that is, the first to third straight ribs 21, 22, 23, the straight rib 26 and the auxiliary straight rib 27 equal, When 10 is produced by injection molding, it is possible to prevent a dent (sink mark) from being generated on the surface of the flat plate portion 13.

なお、平板部１３の裏面における補強部２０の両側の近傍位置には、一対の弾性変形可能なパネル係合爪３０が突設されている。このパネル係合爪３０は、図４（ｂ）に示すように、外側面に複数の凹凸部３１が設けられており、この凹凸部３１の一部がフロアパネル３の配線取出開口４の内側面に弾発係合し得るようになっている。   Note that a pair of elastically deformable panel engagement claws 30 project from the positions near both sides of the reinforcing portion 20 on the back surface of the flat plate portion 13. As shown in FIG. 4B, the panel engaging claw 30 is provided with a plurality of uneven portions 31 on the outer surface, and a part of the uneven portions 31 is inside the wiring extraction opening 4 of the floor panel 3.

Positioning protrusions 50 are respectively provided on the outer sides of the pair of panel engaging claws 30 that are provided in the vicinity of both sides of the reinforcing portion 20 on the back surface of the flat plate portion 13. The positioning protrusion 50 can be fitted into a through hole 49 provided in the mounting edge 4a.

第２実施形態において、その他の部分は第１実施形態と同じであるので、同一部分には同一符号を付して説明は省略する。   In the second embodiment, the other parts are the same as those in the first embodiment, so the same parts are denoted by the same reference numerals and description thereof is omitted.

＜その他の実施形態＞
上記実施形態では、塞ぎ板１０，１０Ａに一つの切欠き１１と、該切欠き１１を開閉する蓋片１２とを設ける場合について説明したが、塞ぎ板１０，１０Ａに複数例えば二つの切欠き１１を設けると共に、各切欠き１１を開閉する蓋片１２を設けるようにしてもよい。 <Other embodiments>
In the above embodiment, the case where one notch 11 and the lid piece 12 for opening and closing the notch 11 are provided in the closing plates 10 and 10A has been described, but a plurality of, for example, two notches 11 are provided in the closing plates 10 and 10A. And a cover piece 12 for opening and closing each notch 11 may be provided.

上記のように構成される実施形態の塞ぎ板１０，１０Ａは、フロアパネル３，３Ａに形成された配線取出開口４の開口縁に段差状に突設された載置用縁部４ａ，４ｂに載置された状態では、平板部１３の上面がフロアパネル３，３Ａの上面と同一の状態で配線取出開口４を塞ぐことができる。
The closing plates 10 and 10A of the embodiment configured as described above are placed on the mounting edges 4a and 4b that project from the opening edge of the wiring extraction opening 4 formed on the floor panels 3 and 3A. In the mounted state, the wiring extraction opening 4 can be closed with the upper surface of the flat plate portion 13 being the same as the upper surfaces of the floor panels 3 and 3A.

フロアパネル３，３Ａに配線する場合は、塞ぎ板１０，１０Ａの平板部１３に形成された配線取出用の切欠き１１の両側辺の薄肉連結部１４をカッター等の工具で切り離し、ヒンジ部１５を介して蓋片１２を下方へ回動して、切欠き１１を開放し、切欠き１１の空間部に例えばタップコード５等を配線する。この際、蓋片１２の裏面に突設された一対の爪部１６を補強部２０における切欠き１１を挟んだ対向部位に突設された受け部１７に係合させることによって切欠き１１の開放状態が維持できるので、配線の取付作業を容易にすると共に、配線の取付状態を安定させることができる。   When wiring to the floor panels 3 and 3A, the thin connecting portions 14 on both sides of the cutout 11 for wiring extraction formed on the flat plate portion 13 of the closing plates 10 and 10A are separated with a tool such as a cutter, and the hinge portion 15 The cover piece 12 is pivoted downward via the notch, the notch 11 is opened, and, for example, the tap cord 5 is wired in the space of the notch 11. At this time, the notch 11 is opened by engaging a pair of claw portions 16 projecting on the back surface of the lid piece 12 with a receiving portion 17 projecting at an opposite portion of the reinforcing portion 20 across the notch 11. Since the state can be maintained, the wiring mounting operation can be facilitated and the wiring mounting state can be stabilized.

レイアウトの変更に伴う配線の変更等によって切欠き１１を塞ぐ場合は、切欠き１１の空間部に配線されたタップコード５等を取り外した後、爪部１６と受け部１７との係合を解いて、蓋片１２を上方へ回動し、蓋片１２の裏面に突設された脚部１８を配線取出開口４の開口縁に突設された載置用縁部４ａ，４ｂ上に載置して切欠き１１を塞ぐ。この状態では、蓋片１２の裏面に突設された脚部１８が配線取出開口４の開口縁に突設された載置用縁部４ａ，４ｂ上に載置されているので、蓋片１２の上面は平板部１３の上面及びフロアパネル３，３Ａの上面と同一になり、段部が生じることがない。また、蓋片１２の裏面に突設された脚部１８に連なって蓋片１２のヒンジ部１５側に向かう補強リブ１９が延設されているので、蓋片１２に強度をもたせることができる。   When the notch 11 is closed by changing the wiring accompanying the layout change, the tap cord 5 wired in the space of the notch 11 is removed, and the engagement between the claw part 16 and the receiving part 17 is released. Then, the lid piece 12 is rotated upward, and the leg portion 18 projecting from the back surface of the lid piece 12 is placed on the placement edge portions 4 a and 4 b projecting from the opening edge of the wiring extraction opening 4. Then, the notch 11 is closed. In this state, the leg 18 projecting from the back surface of the lid piece 12 is placed on the placement edges 4 a and 4 b projecting from the opening edge of the wiring extraction opening 4. Is the same as the upper surface of the flat plate portion 13 and the upper surfaces of the floor panels 3 and 3A, and no stepped portion is formed. Further, since the reinforcing rib 19 extending toward the hinge portion 15 side of the lid piece 12 is extended to the leg portion 18 protruding from the back surface of the lid piece 12, the lid piece 12 can be provided with strength.

また、実施形態の塞ぎ板１０，１０Ａは、ポリプロピレンの射出成形によって塞ぎ板１０，１０Ａと蓋片１２とを切り離さずに一体成形できるので、蓋片１２を切り離して使用するものに比べて金型の形状を簡単にすることができると共に、成形を容易にすることができ、かつ、生産コストの削減が図れる。   Moreover, since the closing plates 10 and 10A of the embodiment can be integrally formed without separating the closing plates 10 and 10A and the lid piece 12 by polypropylene injection molding, the mold is compared with that used by separating the lid piece 12 The shape can be simplified, the molding can be facilitated, and the production cost can be reduced.

また、ポリプロピレンは、引張り強さ，曲げ強さ，剛性等が大きい上、粘性を有するので、ヒンジ部１５を繰返し折り曲げても蓋片１２は塞ぎ板１０，１０Ａから切り離されることはない。   In addition, since polypropylene has high tensile strength, bending strength, rigidity, and the like, and has viscosity, the lid piece 12 is not separated from the closing plates 10 and 10A even when the hinge portion 15 is bent repeatedly.
