Description

本発明は、パネル外周辺からこのパネル外周辺の直交方向内向きに形成したコンセントボックス用開口を、このコンセントボックス用開口の開口周縁に形成した低段面へ着脱自在に載置される開口用蓋で閉蓋する床パネルに関する。 The present invention relates to an opening for detachably mounting an outlet box outlet formed from the outer periphery of the panel inward in the orthogonal direction of the outer periphery of the panel on a lower step surface formed at the opening periphery of the outlet box opening. The present invention relates to a floor panel closed with a lid.

フリーアクセス床は、基礎床面に対し、複数の床パネルを並設して構築する。基礎床面と床パネルとの間の床下空間には、電源ケーブルや通信ケーブルを配設している。このため、使用する床パネルの一部又は全部に、パネル外周辺からこのパネル外周辺の直交方向内向きに形成したコンセントボックス用開口を形成した床パネルが用いられる。コンセントボックス用開口は、コンセントボックスを嵌め込む大きさ又は形状であり、通常、コンセントボックス用開口の開口周縁に形成した低段面へ着脱自在に載置される開口用蓋で閉蓋している。このように、開口用蓋は前記コンセントボックス用開口を閉蓋することが第一であるが、コンセントボックス用開口への装着安定性を確保したり、電源ケーブル又は通信ケーブルのみを引き出せる通線口を設ける等の構造的工夫がなされることが多い。 A free access floor is constructed by arranging a plurality of floor panels side by side on the foundation floor. A power cable and a communication cable are disposed in the underfloor space between the foundation floor and the floor panel. For this reason, the floor panel which formed the opening for outlet boxes formed in the orthogonal direction inward of this panel outer periphery from the outer periphery of this panel to a part or all of the floor panel to be used is used. The outlet box opening has a size or shape into which the outlet box is fitted, and is normally closed with an opening lid that is detachably mounted on the lower step surface formed at the periphery of the opening of the outlet box opening. . As described above, the opening lid is the first to close the outlet box opening, but it is possible to ensure the mounting stability to the outlet box opening or to draw out only the power cable or the communication cable. In many cases, structural measures such as providing the

特許文献１の開口用蓋は、開口用蓋の蓋外周辺に通じた通線口を形成すると共に、この通線口と蓋内周辺の中間に、床パネルのパネル外周辺に沿う補強用凹溝部を設けている。この開口用蓋は、補強用凹溝部と通線開口が設けられない側の蓋外周辺の間で、コンセントボックス用開口の低段面に対応する部位に、係止用爪片を下向きに切り起こして形成しており、係止用爪片を低段面の面周縁に係合して、装着安定性を確保している。 The lid for opening of Patent Document 1 forms a through hole that communicates with the outer periphery of the lid for the opening, and a reinforcing recess along the outer periphery of the floor panel between the through hole and the inner periphery of the lid. A groove is provided. In this opening lid, the locking claw piece is cut downward at a portion corresponding to the lower step surface of the outlet box opening between the reinforcing groove and the outer periphery of the lid where the through-wire opening is not provided. The locking claw pieces are engaged with the peripheral edge of the low step surface to ensure mounting stability.

特許文献２の開口用蓋は、床パネルのパネル外周辺に形成されるコンセントボックス用開口をパネル外周辺の直交方向外向きにのみ抜き出して取り外し可能にしている。具体的には、開口用蓋を構成する平板部と、この平板部から切り起こした舌片が係合することで、コンセントボックス用開口に対する開口用蓋の装着安定性を高めている。通線口は、蓋内周辺に設けた切取片を適宜切り取って形成する。 In the opening lid of Patent Document 2, the outlet box opening formed on the periphery of the floor panel outside the panel is extracted only in the orthogonal direction outward of the panel outer periphery so as to be removable. Specifically, the mounting stability of the opening lid with respect to the outlet box opening is enhanced by the engagement between the flat plate portion constituting the opening lid and the tongue piece cut and raised from the flat plate portion. The through hole is formed by appropriately cutting a cut piece provided around the inside of the lid.

特許文献３の開口用蓋は、蓋外周辺に通線口用の溝状切欠を形成すると共に、この溝状切欠の手前側端に拡幅された幅広部を形成する一方、前記溝状切欠に囲まれていて後から切離されることにより通線口を形成するキャップ状小片を形成している。開口用蓋は、下方に向けて突出し、折り返した板バネ構造の突起片を、コンセントボックス用開口の開口周縁に形成した低段面に設けた係止切欠に係合させて、装着安定性を確保している。突起片は、開口用蓋に開口した操作穴から指で挟んで閉じることにより、係止切欠に対する係合を解除することができる。 The opening lid of Patent Document 3 forms a groove-shaped notch for the through hole at the outer periphery of the lid, and forms a widened portion at the front end of the groove-shaped notch, while the groove-shaped notch A cap-shaped piece that forms a through hole is formed by being surrounded and separated later. The opening lid protrudes downward, and the folded leaf spring structure projecting piece is engaged with a locking notch provided on the lower edge of the opening edge of the outlet box outlet for improved mounting stability. Secured. The projecting piece can be released from the engagement with the locking notch by closing it with a finger from the operation hole opened in the opening lid.

特許文献４の開口用蓋は、直交関係で一体となった塞ぎ板及び通線用板からなり、前記通線用板に通先口を貫設している。この開口用蓋は、コンセントボックス用開口を塞ぎ板で塞ぎ、通線用口が必要になったときは、通線用板でコンセントボックス用開口を塞ぐようにする。コンセントボックス用開口に対する開口用蓋の装着安定性は、塞ぎ板に設けた爪を低段面に係合することにより確保している。特許文献５の開口用蓋は、前記特許文献４と似ており、直交関係で一体となった長辺板部及び短辺板部からなり、長辺板部でコンセントボックス用開口を完全に塞ぎ、短辺板部で通線口を残してコンセントボックス用開口を塞ぐようにしている。 The lid for opening in Patent Document 4 is composed of a closing plate and a wiring board integrated in an orthogonal relationship, and a through hole is provided through the wiring board. This opening lid closes the outlet box opening with a closing plate, and when a wiring opening is required, the outlet box opening is closed with the wiring plate. The mounting stability of the opening lid with respect to the outlet box opening is ensured by engaging a claw provided on the closing plate with the lower step surface. The opening lid of Patent Document 5 is similar to Patent Document 4 and is composed of a long side plate portion and a short side plate portion integrated in an orthogonal relationship, and the outlet side box opening is completely blocked by the long side plate portion. The outlet for the outlet box is blocked by leaving the opening at the short side plate.

特許文献１の開口用蓋は、電源ケーブル又は通信ケーブルを引き出さないときでも常に通線口が開口している。このため、ハイヒールの踵が落ち込む危険性を回避するには、平均的なハイヒールの踵の直径＝８mmを超える通線口を設けることができず、通線口から引き出せる電源ケーブル又は通信ケーブルが限定されてしまう。ところが、一般のオフィスで使用されるパソコン、コピー機、テーブルタップ等の電源ケーブルは直径９mm以上のものが多い。よって、ハイヒールの踵が落ち込む危険性のない小さな通線口では、実用上ほとんど使用できず、前記電源ケーブルを引き出すためには、別途大きな通線口を設けた開口用蓋に交換する必要がある。 The opening lid of Patent Document 1 always has a through opening even when the power cable or the communication cable is not pulled out. For this reason, in order to avoid the danger that the heel of the high heel falls, it is not possible to provide a wiring hole exceeding the average diameter of the heel of the high heel = 8 mm, and the power cable or communication cable that can be drawn out from the wiring hole is limited. It will be. However, power cables for personal computers, photocopiers, table taps, etc. used in general offices often have a diameter of 9 mm or more. Therefore, it is practically impossible to use a small wire opening with no risk of the heels of the high heels falling, and in order to pull out the power cable, it is necessary to replace it with an opening lid provided with a separate large wire opening. .

特許文献２の開口用蓋は、必要に応じて切取片を切り取って通線口を開口できるので、通線口を大きくすることができる。しかし、一度切取片を折り取ってしまうと、再び通線口を塞ぐことができず、電源ケーブル等の引き出しの必要がなくなると、ハイヒールの踵が嵌まり込む大きさの通線口が残ってしまう問題がある。これに対し、切取片は折り取らずに折り曲げて通線口を開口し、通線口が不要になれば再び切取片を曲げ戻して通線口を塞ぐことが考えられる。しかし、曲げ戻された切取片は強度低下を来しており、人や台車が頻繁に通過すると、繰り返し荷重によって切取片が疲労破壊を起こしてしまう虞れが否めない。更に、切取片は、何度も折り曲げると、最期には切り取れてしまう問題もある。 Since the lid for opening of patent document 2 can cut a cut piece as needed and open a through-hole, it can enlarge a through-hole. However, once the cut piece is broken, it cannot be closed again, and when there is no need to pull out the power cable or the like, there remains a passageway that fits into the heel of the high heel. There is a problem. On the other hand, it is conceivable that the cut piece is bent without opening, and the through hole is opened, and if the through hole is no longer necessary, the cut piece is bent back again to close the through hole. However, the cut-back piece that has been bent back has been reduced in strength, and if a person or a trolley passes frequently, there is a possibility that the cut-out piece will cause fatigue failure due to repeated loads. Furthermore, if the cut piece is bent many times, there is a problem that the cut piece is cut at the end.

特許文献３の開口用蓋は、通線口を開口するために切り取ったキャップ状小片を、通線口の奥側の辺部とコンセントボックス用開口の低段面とに載置することにより、再び通線口を塞ぐことができる。しかし、これは切り取ったキャップ状小片を保管及び管理することを前提としており、手間がかかるほか、小さな部材であるキャップ状小片を紛失してしまう虞れがある。また、開口用蓋から独立したキャップ状小片は、上記特許文献２同様、繰り返し荷重によってキャップ状小片自体、場合によってはキャップ状小片を載置する周辺部分が疲労破壊を起こしてしまう問題がある。このほか、キャップ状小片は、低コストで破壊強度や耐燃性に優れる鋼板製とすることが困難で、破壊強度や耐燃性に問題がある樹脂成形品や、高コストの鋳造品にならざるを得ない問題もある。 The lid for opening of Patent Document 3 is configured by placing a cap-shaped piece cut out to open the through hole on the side portion on the back side of the through hole and the lower step surface of the outlet box opening. You can close the entrance again. However, this is based on the premise that the cut cap-shaped piece is stored and managed, which is troublesome and may cause loss of the cap-shaped piece, which is a small member. In addition, the cap-shaped piece independent of the opening lid has a problem that fatigue failure occurs in the cap-shaped piece itself or, in some cases, the peripheral portion on which the cap-shaped piece is placed due to repeated loads, as in Patent Document 2. In addition, it is difficult to make cap-shaped pieces from steel plates that are low in cost and excellent in fracture strength and flame resistance, and must be resin molded products that have problems in fracture strength and flame resistance, or high-cost cast products. There are also problems that cannot be obtained.

特許文献４又は特許文献５の開口用蓋は、上記特許文献１〜特許文献３に見られた問題が解決されている。しかし、開口用蓋を回転させて通線用板を低段面に載置させた通線取付状態では、塞ぎ板が床パネルの底面から基礎床面に向けて突出状態で垂下されるため、通線口へ電源ケーブル又は通信ケーブルを導く配線空間を阻害し、ケーブルが損傷する虞れがある。これは、特に低床型床パネルの場合に問題となり、床高さが50mm以下の超低床型床パネルの場合には垂下した塞ぎ板が基礎床面に干渉することとなる。そこで、大きな通線口が容易に形成できると共に、通線口が不要になれば容易かつ確実に通線口を塞ぐことができ、しかも基礎床面に向けて床パネルの底面から突出する部分のない開口用蓋によりコンセントボックス用開口を塞ぐことのできる床パネルを開発するため、検討した。 In the opening lid of Patent Literature 4 or Patent Literature 5, the problems found in Patent Literature 1 to Patent Literature 3 are solved. However, in the through-line mounting state where the opening lid is rotated and the through-line plate is placed on the low step surface, the closing plate is suspended in a protruding state from the bottom surface of the floor panel toward the base floor surface, There is a possibility that the wiring space for leading the power cable or communication cable to the through hole is obstructed and the cable is damaged. This is a problem particularly in the case of a low floor type floor panel, and in the case of an ultra low floor type floor panel having a floor height of 50 mm or less, a suspended cover board interferes with the foundation floor surface. Therefore, a large through hole can be easily formed, and if no through hole is required, the through hole can be easily and reliably closed, and the portion protruding from the bottom surface of the floor panel toward the foundation floor surface In order to develop a floor panel that can close the opening for the outlet box with no opening lid, it was studied.

検討の結果開発したものが、パネル外周辺からこのパネル外周辺の直交方向内向きに形成したコンセントボックス用開口を、このコンセントボックス用開口の開口周縁に形成した低段面へ着脱自在に載置される開口用蓋で閉蓋する床パネルにおいて、開口用蓋は、パネル外周辺に同方向に延びる蓋外周辺と、コンセントボックス用開口の周縁形状に倣った蓋内周辺とに囲まれた平面視形状で、この開口用蓋におけるパネル外周辺の直交方向の幅がコンセントボックス用開口におけるパネル外周辺の直交方向の幅に低段面におけるパネル外周辺の直交方向の幅を合わせた幅よりパネル外周辺の直交方向の低段面の幅以下で狭くし、開口用蓋及びコンセントボックス用開口それぞれに互いに係合する蓋側係合手段及び開口側係合手段を設けてなり、開口側係合手段は、蓋側係合手段を係合した開口用蓋が蓋外周辺をパネル外周辺に連続させる標準取付状態となる標準位置と、蓋側係合手段を係合した開口用蓋が蓋外周辺をパネル外周辺の直交方向内向きにずらした通線取付状態となる通線位置とに設けてなり、前記標準位置と通線位置とのパネル外周辺の直交方向の間隔がパネル外周辺の直交方向の低段面の幅以下である床パネルである。 As a result of the study, the developed outlet box for the outlet box formed from the outer periphery of the panel inward in the orthogonal direction around the outer periphery of the panel is detachably mounted on the lower step surface formed at the periphery of the opening for the outlet box. In the floor panel closed by the opening lid, the opening lid is a plane surrounded by the outer periphery of the lid extending in the same direction around the outer periphery of the panel and the inner periphery of the lid following the peripheral shape of the outlet box opening. in visual form, the panel than the width of the width in the orthogonal direction is the sum of orthogonal width of the panel outer periphery of the low-stage surface in the orthogonal direction of the width of the peripheral panel outside the outlet box opening of the panel outside the periphery of the opening lid narrowed by less than the width of the low level portion of the orthogonal direction around the outer, it is provided a cover-side engagement means and the opening-side engagement means engage one another in each opening lid and the opening-outlet box Opening side engagement means, and the standard positions opening lid engaged the lid-side engagement means is a standard attachment state to be continuous around the outside panel peripheral outer lid, opening engaged the lid-side engagement means The lid is provided at a wiring position where the outer periphery of the lid is shifted inwardly in the orthogonal direction around the outer periphery of the panel, and the interval between the standard position and the peripheral position in the orthogonal direction between the outer periphery of the panel is provided. It is a floor panel that is equal to or less than the width of the low step surface in the orthogonal direction around the outside of the panel.

本発明の床パネルは、コンセントボックス用開口に対し、パネル外周辺の直交方向にずれた複数の位置で開口用蓋を選択的に載置することで、前記パネル外周辺の直交方向にずれた範囲の通線口を、蓋外周辺と隣接する床パネルのパネル外周辺との間に形成する。形成される通線口は、開口用蓋におけるパネル外周辺の直交方向の幅がコンセントボックス用開口におけるパネル外周辺の直交方向の幅に低段面におけるパネル外周辺の直交方向の幅を合わせた幅よりパネル外周辺の直交方向の低段面の幅以下で狭くした幅（以下、ずらし幅）を短辺、開口用蓋の蓋外周辺の長さを長辺とする略長方形状になる。これから、ずらし幅の最大はパネル外周辺の直交方向の低段面の幅に等しくなる。 The floor panel of the present invention is shifted in the orthogonal direction of the outer periphery of the panel by selectively placing the opening lid at a plurality of positions shifted in the orthogonal direction of the outer periphery of the panel with respect to the opening for the outlet box. A through hole of the range is formed between the outer periphery of the lid and the outer periphery of the panel of the adjacent floor panel. The width of the opening in the orthogonal direction around the outer periphery of the panel in the lid for opening is equal to the width in the orthogonal direction around the outer periphery of the panel in the opening for the outlet box. The width becomes narrower than the width of the lower step surface in the orthogonal direction around the outside of the panel (hereinafter referred to as the shift width) as a short side, and the length around the outside of the lid of the opening lid becomes a substantially rectangular shape. Now, the maximum displacement width ing equal to the width of the low-stage surface orthogonal directions around the outer panel.

これにより、開口用蓋をパネル外周辺の直交方向にずらしても、ずらし幅の範囲を低段面が塞いでいることになり、隙間を残さない。この場合、ずらし幅の最大は低段面のパネル外周辺の直交方向の幅になるから、最大の通線口は、低段面のパネル外周辺の直交方向の幅を短辺、開口用蓋の蓋外周辺を長辺とする略長方形状になる。 This ensures that even by shifting the opening lid in the direction perpendicular to the peripheral outer panel, becomes the range of shifting widths that are at low level portion is closed, leaving no gap. In this case, since the maximum shift width is the width in the orthogonal direction around the outside of the low-level surface, the maximum through-hole is the short side with the width in the orthogonal direction around the outside of the low-level panel, and the lid for the opening. It becomes the substantially rectangular shape which makes the outer periphery of a lid | cover long side.

実際には、床パネルの表面にはカーペット等を貼着するので、隙間が残っても外見上隠すことができるため、ハイヒールの踵が落ち込まない大きさの隙間、すなわち８mm未満であれば、常時開口していても実害はないと言える。そこで、パネル外周辺の直交方向の低段面の幅と、ハイヒールの踵が落ち込まない大きさの隙間＝８mm未満の隙間との和を最大としてもよい。この場合、ずらし幅の最大は低段面のパネル外周辺の直交方向の幅と、ハイヒールの踵が落ち込まない大きさの隙間との和になるから、最大の通線口は、低段面のパネル外周辺の直交方向の幅とハイヒールの踵が落ち込まない大きさの隙間との和を短辺、開口用蓋の蓋外周辺を長辺とする略長方形状になる。 Actually, carpet or the like is stuck on the surface of the floor panel, so even if there is a gap, it can be concealed in appearance, so if the gap is high enough that the heels of the high heel do not fall, that is, less than 8 mm, always It can be said that there is no real harm even if it is open. Therefore, the width of the low level portion of the orthogonal directions around the outside panel, the sum may be up to the clearance of less than gap = 8 mm in size heeled heel does not depress. In this case, the maximum shift width is the sum of the width in the orthogonal direction around the outside of the panel on the low step surface and the gap that does not allow the heel of the high heel to fall. It becomes a substantially rectangular shape with the short side as the sum of the width in the orthogonal direction around the outer periphery of the panel and the gap of a size that does not allow the heel of the high heel to fall, and the longer side as the outer periphery of the lid for the opening.

本発明の床パネルでは、上述のパネル外周辺の直交方向の低段面の幅内であれば、複数の位置で開口用蓋を選択的にコンセントボックス用開口の低段面へ着脱自在に載置できる。しかし、実用的には、コンセントボックス用開口を塞ぐ標準取付状態と、通線口を形成する通線取付状態とを実現できればよい。そこで、開口側係合手段は、開口用蓋に設けた蓋側係合手段に対し、蓋側係合手段を係合した開口用蓋が蓋外周辺をパネル外周辺に連続させる標準取付状態となる標準位置と、蓋側係合手段を係合した開口用蓋が蓋外周辺をパネル外周辺の直交方向内向きにずらした通線取付状態となる通線位置とに設けてなり、前記標準位置と通線位置とのパネル外周辺の直交方向の間隔がパネル外周辺の直交方向の低段面の幅以下であればよい。 In the floor panel of the present invention, the opening lid is selectively detachably mounted on the lower stage surface of the outlet box opening at a plurality of positions within the width of the lower stage surface in the orthogonal direction around the outside of the panel. Can be placed. However, practically, it is only necessary to realize a standard mounting state in which the outlet box opening is closed and a wiring mounting state in which a wiring port is formed. Therefore, the opening-side engagement means has a standard mounting state in which the opening lid engaged with the lid-side engaging means is connected to the lid-side engaging means provided on the opening lid so that the outer periphery of the lid continues to the outer periphery of the panel. The standard position and the opening lid engaged with the lid-side engaging means is provided at the line position where the outer periphery of the lid is shifted inwardly in the orthogonal direction of the outer periphery of the panel. The distance between the position and the line position in the orthogonal direction around the outside of the panel may be equal to or less than the width of the low step surface in the orthogonal direction around the outside of the panel .

ここで、蓋側係合手段及び開口側係合手段は、コンセントボックス用開口に対する開口用蓋の装着安定性を、選択的な複数の位置で等しく発揮できる構成の組み合わせが好ましい。こうした蓋側係合手段及び開口側係合手段としては、開口用蓋から下方に向けて突設させた突起である蓋側係合手段に対して、(a)低段面に開口した前記突起を嵌め込む嵌合孔である開口側係合手段、又は(b)開口側係合手段は低段面の面周縁に形成した前記突起を係合させる係合凹部である開口側係合手段の組み合わせが考えられる。これら蓋側係合手段である突起及び開口側係合手段である嵌合孔又は係合凹部は、例えば上述の標準位置又は通線位置に対して２カ所ずつ設け、各嵌合孔又は係合凹部に対して異なる方向から対応する突起をそれぞれ当接状態で嵌合又は係合させると、各突起と各嵌合孔又は各係合凹部との嵌合又は係合が緊密になり、コンセントボックス用開口に対する開口用蓋の装着安定性を高めることができる。 Here, the lid-side engagement means and the opening-side engagement means are preferably a combination of configurations that can equally exhibit the mounting stability of the opening lid with respect to the outlet box opening at a plurality of selective positions. Such lid-side engagement means and opening-side engagement means include: (a) the protrusions that are open on the lower surface with respect to the lid-side engagement means that is a protrusion protruding downward from the opening lid. An opening side engagement means that is a fitting hole into which the screw is fitted, or (b) an opening side engagement means that is an engagement concave portion that engages the projection formed on the peripheral edge of the low step surface. Combinations are possible. The projections that are the lid-side engaging means and the fitting holes or the engaging recesses that are the opening-side engaging means are provided, for example, at two positions with respect to the standard position or the through-line position described above. When the corresponding protrusions are fitted or engaged with each other in a contact state from different directions with respect to the recess, the fitting or engagement between each protrusion and each fitting hole or each engagement recess becomes tight, and the outlet box The mounting stability of the opening lid with respect to the opening for use can be improved.

本発明によれば、パネル外周辺から該パネル外周辺の直交方向内向きに形成したコンセントボックス用開口を、このコンセントボックス用開口の開口周縁に形成した低段面へ着脱自在に載置される開口用蓋で閉蓋する床パネルにおいて、パネル外周辺の直交方向にずれた複数の位置、例えば蓋側係合手段を係合した開口用蓋が蓋外周辺をパネル外周辺に連続させる標準取付状態となる標準位置と、蓋側係合手段を係合した開口用蓋が蓋外周辺をパネル外周辺の直交方向内向きにずらした通線取付状態となる通線位置とに、開口用蓋を置き換えるだけで、ハイヒールの踵が落ち込む大きさの隙間を残すことなく、通線口を容易に形成し、再び塞ぐことができる。 According to the present invention, the outlet box opening formed from the outer periphery of the panel inwardly in the orthogonal direction of the outer periphery of the panel is detachably mounted on the low step surface formed at the periphery of the opening of the outlet box opening. For floor panels that are closed with an opening lid, a plurality of positions shifted in the orthogonal direction around the outer periphery of the panel, for example, an opening lid that engages the lid side engaging means makes the outer periphery of the lid continuous with the outer periphery of the panel. The opening lid is located at the standard position where the lid is engaged and the opening position where the opening lid engaged with the lid side engaging means is shifted to the perpendicular direction inward of the outer periphery of the panel in the orthogonal direction. By simply replacing, the through hole can be easily formed and closed again without leaving a gap large enough for the heel of the high heel to fall.

上記標準位置及び通線位置の選択は、コンセントボックス用開口に対する開口用蓋の装着安定性を確保する蓋側係合手段及び開口側係合手段によって実現する。ここで、前記蓋側係合手段は開口用蓋から下方に向けて突設させた突起として、また開口側係合手段は低段面に開口した前記突起を嵌め込む嵌合孔又は低段面の面周縁に形成した係合凹部として形成でき、標準位置及び通線位置の設定は容易にできる。これにより、開口用蓋を載置する位置を増やすこともでき、必要な通線口の大きさを自由に設定できるようになる。しかも、本発明の開口用蓋は基礎床面に向けて床パネルの底面から飛び出す部分を有していないので、形成した通線口へ導く電源ケーブル又は通信ケーブルが傷つく虞れがない利点がある。 The selection of the standard position and the line position is realized by a lid-side engagement means and an opening-side engagement means that ensure mounting stability of the opening lid with respect to the outlet box opening. Here, the lid-side engaging means is a protrusion projecting downward from the opening lid, and the opening-side engaging means is a fitting hole or a low step surface into which the protrusion opened on the low step surface is fitted. It can be formed as an engagement recess formed on the peripheral edge of the surface, and the standard position and the line position can be easily set. Thereby, the position which mounts the lid | cover for opening can also be increased, and the magnitude | size of a required wire opening can be freely set now. Moreover, since the opening lid of the present invention does not have a portion that protrudes from the bottom surface of the floor panel toward the base floor surface, there is an advantage that the power cable or communication cable that leads to the formed wiring opening is not damaged. .

以下、本発明の実施形態について図を参照しながら説明する。図１は本発明の開口用蓋と床パネルとの関係を表した斜視図、図２は開口用蓋を標準取付状態で装着した床パネルの平面図、図３は図２中Ａ−Ａ拡大断面図、図４は図２中Ｂ−Ｂ拡大断面図、図５は開口用蓋を通線取付状態で装着した床パネルの平面図、図６は図５中Ｃ−Ｃ拡大断面図、図７は床パネルの敷設状態を表す平面図であり、図８〜図14はそれぞれ大きさの異なる通線口４を形成した状態の床パネルを表す平面図である。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the relationship between the opening lid and the floor panel of the present invention, FIG. 2 is a plan view of the floor panel with the opening lid mounted in a standard mounting state, and FIG. 3 is an enlarged view of AA in FIG. 4 is an enlarged sectional view taken along the line BB in FIG. 2, FIG. 5 is a plan view of the floor panel mounted with the opening lid attached through the line, and FIG. 6 is an enlarged sectional view taken along the line CC in FIG. 7 is a plan view showing the laying state of the floor panel, and FIGS. 8 to 14 are plan views showing the floor panel in a state in which the through holes 4 having different sizes are formed.

本例の床パネル１は、平面視正方形で、パネル外周辺11の一つにコンセントボックス等を取り付けるコンセントボックス用開口２を設けている。コンセントボックス用開口２は、装着するコンセントボックス等に合わせて、大きさ又は形状を自由に設定できる。本例のコンセントボックス用開口２は、図１に見られるように、パネル外周辺11の延在方向の長さに対し、パネル外周辺11の直交方向の幅が約半分の大きさからなる平面視略長方形である。本例では、隣接する床パネル１,１を互いのコンセントボックス用開口２が突き合わせる位置関係で並べると、両コンセントボックス用開口により平面視略正方形の開口が形成されるようにしている。これは、設置できるコンセントボックスの大きさを選択できる使用上の利点をもたらしている。低段面21は、コンセントボックス用開口２の開口周縁に沿って開口用蓋３の厚さで下がった平面で、前記開口周縁から一定幅で形成している。このコンセントボックス用開口２は、コンセントボックス等を取り付けない場合、開口用蓋３を低段面21に載置することにより塞いでいる。 The floor panel 1 of this example has a square shape in plan view, and is provided with an outlet box opening 2 for attaching an outlet box or the like to one of the outer periphery 11 outside the panel. The size or shape of the outlet box opening 2 can be freely set according to the outlet box to be mounted. As shown in FIG. 1, the outlet box opening 2 of this example is a plane in which the width in the orthogonal direction of the panel outer periphery 11 is about half the length of the panel outer periphery 11 in the extending direction. It is a substantially rectangular shape. In this example, when adjacent floor panels 1 and 1 are arranged in such a positional relationship that the outlet box openings 2 abut each other, a substantially square opening in plan view is formed by both outlet box openings. This has the advantage of being able to select the size of the outlet box that can be installed. The low step surface 21 is a plane that is lowered by the thickness of the opening lid 3 along the opening periphery of the outlet box opening 2 and is formed with a constant width from the opening periphery. The outlet box opening 2 is closed by placing the opening lid 3 on the lower step surface 21 when an outlet box or the like is not attached.

本例の開口用蓋３は、図２に見られるように、パネル外周辺11に同方向に延びる蓋外周辺38と、コンセントボックス用開口の周縁形状に倣った蓋内周辺39とに囲まれた平面視形状の平板部31と、前記平板部31の蓋外周辺38から下向きに折り曲げて延設された補強片部32とからなる。平板部31は、コンセントボックス用開口２の開口周縁に設けた低段面21に、蓋内周辺39に続く周縁部分が接面状態で載置され、開口用蓋３本来の働きとしてコンセントボックス用開口２を塞ぐ役割を有している。これに対し、補強片部32は、低段面21上に載置されない平板部31の蓋外周辺38を補強する補強リブとしての役割を有し、開口用蓋３に荷重が加わった際、平板部31の撓みを抑制する。これから、補強片部32は、必要強度や板厚によって異なるものの、配線空間を阻害しないように床パネル１の底面から突出させない長さである必要があり、好ましくは床パネル１の厚みより幾分小さい長さにすると開口用蓋３を載置した状態での床パネル１の取り扱い性もよい。 As shown in FIG. 2, the opening lid 3 of this example is surrounded by an outer periphery 38 extending in the same direction as the outer periphery 11 of the panel and an inner periphery 39 following the peripheral shape of the outlet box opening. A flat plate portion 31 having a planar view shape, and a reinforcing piece portion 32 that is bent downward from the outer periphery 38 of the lid of the flat plate portion 31 and extends downward. The flat plate portion 31 is placed on the lower step surface 21 provided on the peripheral edge of the opening 2 for the outlet box with the peripheral edge portion continuing from the inner periphery 39 in the lid surface, and the opening lid 3 originally functions for the outlet box. It has a role of closing the opening 2. On the other hand, the reinforcing piece portion 32 has a role as a reinforcing rib that reinforces the outer periphery 38 of the flat plate portion 31 that is not placed on the low step surface 21, and when a load is applied to the opening lid 3, The bending of the flat plate portion 31 is suppressed. From this, the reinforcing piece 32 needs to have a length that does not protrude from the bottom surface of the floor panel 1 so as not to disturb the wiring space, although it varies depending on the required strength and plate thickness, and is preferably somewhat larger than the thickness of the floor panel 1. When the length is small, the handleability of the floor panel 1 with the opening lid 3 placed thereon is good.

開口用蓋３は、蓋側係合手段として、平板部31から切り起こした一対の突起33を下方に向けて突出させている。また、コンセントボックス用開口２は、開口側係合手段として、低段面21の面周縁を切り欠いて、一対の標準位置用係合凹部22,22と、同じく一対の通線位置用係合凹部23,23とを形成している。開口用蓋３は、突起33と選択した標準位置用係合凹部22又は通線位置用係合凹部23のいずれかとを係合させて、コンセントボックス用開口２に対して標準取付状態又は通線取付状態のいずれかで載置する。このとき、突起33は標準位置用係合凹部22又は通線位置用係合凹部23のいずれかと係合することで、特に開口用蓋３のパネル外周辺11の直交内外方向への位置規制を図り、装着安定性を高めている。 The opening lid 3 has a pair of protrusions 33 cut and raised from the flat plate portion 31 projecting downward as lid-side engaging means. In addition, the outlet box opening 2 serves as an opening-side engaging means by cutting out the peripheral edge of the low step surface 21 to form a pair of standard position engaging recesses 22 and 22 and a pair of wire position engaging portions. Recesses 23 and 23 are formed. The opening lid 3 is engaged with the projection 33 and either the selected standard position engaging recess 22 or the wiring position engaging recess 23 so as to be in a standard mounting state or wiring with respect to the outlet box opening 2. Place in any of the attached states. At this time, the protrusion 33 is engaged with either the standard position engaging recess 22 or the passage position engaging recess 23 to restrict the position of the opening lid 3 in the orthogonal inner / outer direction of the panel outer periphery 11 in particular. Increases the mounting stability.

本例では、一対設けた突起33,33は、図３及び図４に見られるように、下方に向けて徐変に広がる「ハ」の字状の関係となるように、それぞれパネル外周辺11の延在方向に傾斜させている。これにより、開口用蓋３は、前記一対の突起33,33を低段面21の標準位置用係合凹部22又は通線位置用係合凹部23間に圧入することができ、低段面21に対する開口用蓋３の浮き上がりを防止し、コンセントボックス用開口２に対する開口用蓋３の装着安定性を高めている。標準位置用係合凹部22,22は、突起33を係合したときに開口用蓋３の蓋外周辺38がパネル外周辺11に連続させる標準取付状態となる標準位置に設けている。また、通線位置用係合凹部23,23は、突起33を係合したときに開口用蓋３の蓋外周辺38をパネル外周辺11の直交方向内向きにずらし、隣接する床パネル１との間に大きな通線口４を形成する通線取付状態となる通線位置に設けている。 In this example, as shown in FIGS. 3 and 4, the pair of protrusions 33, 33 are respectively arranged on the outer periphery 11 of the panel so as to have a “C” -shaped relationship that gradually spreads downward. It is inclined in the extending direction. As a result, the opening lid 3 can press-fit the pair of protrusions 33, 33 between the standard position engaging recess 22 or the passage position engaging recess 23 of the low step surface 21. The opening lid 3 is prevented from being lifted with respect to the outlet, and the mounting stability of the opening lid 3 with respect to the outlet box opening 2 is improved. The standard position engaging recesses 22 and 22 are provided at standard positions where the outer periphery 38 of the lid 3 for the opening 3 is continuously attached to the outer periphery 11 of the panel when the protrusion 33 is engaged. Further, the engagement recesses 23, 23 for the line position shift the outer periphery 38 of the lid 3 for the opening 3 inwardly in the direction orthogonal to the outer periphery 11 of the panel when the projection 33 is engaged with the adjacent floor panel 1. Are provided at the line positions where the large line opening 4 is formed and the line is attached.

標準取付状態では、図２に見られるように、開口用蓋３の補強片部32の外面と床パネル１のパネル外周辺11とが同一線上に揃うようにしている。このとき、上下方向にわたる通線用凹部34を補強片部32に形成しておくと、隣接する床パネル１との間に小さな通線口４を形成できる。この小さな通線口４は、主として直径８mm以下の小径コードを引き出すために用いるもので、隣接する床パネル１に装着した開口用蓋３の小さな通線口４と合わせられるようにするため、補強片部32の左右方向の中間位置に形成するとよい。通常、小さな通線口４は、床パネル１の表面に貼着されるカーペット等 (表面仕上げ材、図示省略)に覆われて塞がれる。本例の小さな通線口４は、こうしてカーペット等に塞がれた状態でも、ハイヒールの踵がカーペット等を破って落ち込む危険性がないように、８mm以下の幅に設定する。ここで、通線用凹部34を設けない場合、標準位置用係合凹部22を設ける標準位置を８mm以下の寸法で床パネル１の中央側にずらし、標準取付状態において補強片部32と隣接する床パネル１との間に蓋外周辺38の長さを長辺とする小さな通線口４が形成されるようにするとよい。通常、隣接する床パネル１,１間には１mm程度の隙間を確保した状態で敷設するから、小さな通線口４はこの隙間を含めて８mm以下の幅になるよう設定する。 In the standard mounting state, as shown in FIG. 2, the outer surface of the reinforcing piece 32 of the opening lid 3 and the panel outer periphery 11 of the floor panel 1 are aligned on the same line. At this time, if a through-hole recess 34 extending in the vertical direction is formed in the reinforcing piece 32, a small through-hole 4 can be formed between the adjacent floor panels 1. This small wire opening 4 is mainly used for drawing out a small-diameter cord having a diameter of 8 mm or less, and is reinforced to be matched with the small wire opening 4 of the opening lid 3 attached to the adjacent floor panel 1. It is good to form in the intermediate position of the left-right direction of the piece part 32. FIG. Usually, the small wire opening 4 is covered and closed by a carpet or the like (surface finishing material, not shown) attached to the surface of the floor panel 1. The small through-hole 4 in this example is set to a width of 8 mm or less so that there is no risk that the high-heeled heel breaks through the carpet or the like even if it is blocked by the carpet or the like. Here, when the through-hole recess 34 is not provided, the standard position where the standard-position engagement recess 22 is provided is shifted to the center side of the floor panel 1 with a dimension of 8 mm or less, and adjacent to the reinforcing piece 32 in the standard mounting state. It is preferable that a small wire opening 4 having a long side of the length of the outer periphery 38 outside the lid is formed between the floor panel 1 and the floor panel 1. Usually, since it lays in a state where a gap of about 1 mm is secured between the adjacent floor panels 1, 1, the small passage 4 is set to have a width of 8 mm or less including this gap.

通線取付状態では、図５に見られるように、開口用蓋３の補強片部32の外面と床パネル１のパネル外周辺11とがずれて、補強片部32と隣接する床パネル１との間に大きな通線口４が形成される。本例の通線位置用係合凹部23は、低段面21のパネル外周辺11の直交方向の幅の範囲内でずらし幅、すなわちパネル外周辺11の直交方向内向きに約７mmのずらし幅で、標準位置用係合凹部22から離れて設けている。これにより、通線取付状態では、開口用蓋３の補強片部32は床パネル１のパネル外周辺11に対して内方へ約７mm入り込んだ位置にずれる。よって、開口用蓋３の補強片部32の外側には、隣接する床パネル１,１相互間の隙間が加わって、隣接する床パネル１との間に約８mm幅を有し、更に通線用凹部34の部分では隣接する床パネル１との間に約15mm幅を有する大きな通線口４が形成される。 In the line-attached state, as shown in FIG. 5, the outer surface of the reinforcing piece portion 32 of the opening lid 3 and the outer panel periphery 11 of the floor panel 1 are displaced, and the floor panel 1 adjacent to the reinforcing piece portion 32 A large through hole 4 is formed between the two. In this example, the engagement recess 23 for the line position is shifted within the range of the width of the low step surface 21 in the orthogonal direction of the outer periphery 11 of the panel, that is, the shift width of about 7 mm inward in the orthogonal direction of the outer periphery 11 of the panel. Thus, it is provided apart from the standard position engaging recess 22. As a result, the reinforcing piece 32 of the opening lid 3 shifts to a position where it enters about 7 mm inward with respect to the panel outer periphery 11 of the floor panel 1 in the state where the line is attached. Therefore, a gap between the adjacent floor panels 1 and 1 is added to the outside of the reinforcing piece portion 32 of the opening lid 3 so as to have a width of about 8 mm between the adjacent floor panels 1 and further through the wire. A large through hole 4 having a width of about 15 mm is formed between the adjacent concave panel 34 and the adjacent floor panel 1.

本例では、蓋外周辺38がパネル外周辺11に揃う標準取付状態と、ずらし幅だけ蓋外周辺38がパネル外周辺11より内向きに離隔する通線取付状態とを選択して、開口用蓋３をコンセントボックス用開口２の低段面21に載置することができる。ここで、通線取付状態では、低段面21の段差部24と、開口用蓋３の折り返し縁部36とが密着する位置にすることが望ましいため、開口用蓋３の移動幅は前記ずらし幅に略等しく、このずらし幅が通線口４の拡大幅となる。また、本例では、低段面21の付近に位置する両端部を、開口用蓋３の補強片部32が干渉しないように、パネル外周辺11からパネル外周辺11の直交方向内向きに引っ込めた位置に形成している。低段面21のパネル外周辺11付近に位置する両端部をどの程度引っ込めるかについてであるが、例えば標準取付状態の開口用蓋３ができるだけパネル外周辺11の直交方向外方寄りで支持されるように考慮して、開口用蓋３の補強片部32が干渉しない必要最低限の幅、すなわち開口用蓋３のずらし幅に相当する大きさだけ引っ込めるとよい。 In this example, select the standard mounting state where the outer periphery 38 of the lid is aligned with the outer periphery 11 of the panel, and the through-wire mounting state where the outer periphery 38 of the lid is spaced inward from the outer periphery 11 of the panel for the opening. The lid 3 can be placed on the lower step surface 21 of the outlet box opening 2. Here, since it is desirable that the stepped portion 24 of the low stepped surface 21 and the folded-back edge portion 36 of the opening lid 3 are in close contact with each other when the line is attached, the movement width of the opening lid 3 is shifted as described above. It is substantially equal to the width, and this shift width becomes the enlarged width of the through hole 4. Further, in this example, both end portions located in the vicinity of the lower step surface 21 are retracted inward in the orthogonal direction from the panel outer periphery 11 to the panel outer periphery 11 so that the reinforcing piece portion 32 of the opening lid 3 does not interfere. It is formed at the position. The extent to which both ends of the low step surface 21 located near the outer periphery 11 of the panel are retracted is, for example, the lid 3 for opening in the standard mounting state is supported as close to the outer periphery in the orthogonal direction as possible. In view of the above, it is preferable to retract by a necessary minimum width at which the reinforcing piece portion 32 of the opening lid 3 does not interfere, that is, a size corresponding to the shifting width of the opening lid 3.

低段面21に載置してコンセントボックス用開口２を閉蓋した標準取付状態又は通線取付状態のいずれでも、開口用蓋３の表面と床パネル１の表面とが面一に揃えることが望ましい。ところが、床パネル１の表面に対する低段面21の深さは、取り付けるコンセントボックス等の要求から比較的深く、実際上3.5mm程度が必要とされる。これに対し、開口用蓋３は薄くても必要強度を満足でき、実際上は1.6mm程度の板厚であればよいとされる。これから、床パネル１の表面と開口用蓋３の表面とを面一に揃えるには、開口用蓋３に何らかの嵩上げ手段が必要となる。 The surface of the opening lid 3 and the surface of the floor panel 1 may be flush with each other in either the standard mounting state where the outlet box opening 2 is closed by being placed on the low-level surface 21 or the wiring line mounting state. desirable. However, the depth of the low step surface 21 with respect to the surface of the floor panel 1 is relatively deep due to the requirement of an outlet box to be attached, and is actually required to be about 3.5 mm. On the other hand, even if the opening lid 3 is thin, the required strength can be satisfied, and in practice, a thickness of about 1.6 mm is sufficient. From now on, in order to make the surface of the floor panel 1 and the surface of the opening lid 3 flush with each other, some kind of raising means is required for the opening lid 3.

本例は、前記嵩上げ手段として、図３及び図４に見られるように、まず平板部31の蓋内周辺39のうち、パネル外周辺11の直交方向である短辺側に段押し部35,35を設けている。本例の段押し部35は、低段面21の深さと開口用蓋３の平板部31の板厚との差分だけ前記平板部31から下方へ突出させており、開口用蓋３の表面と床パネル１の表面とを面一に揃えている。この段押し部35は、開口用蓋３の表面に貼着するカーペット等により隠れるため、形状又は大きさをある程度自由に設定することができる。しかし、あまり広幅の段差部24は、経時的に劣化した前記カーペット等が落ち込んでしまう虞れがあるため、こうしたカーペット等の落ち込みを招かない程度の幅に抑えることが望ましい。 In this example, as shown in FIGS. 3 and 4, as the raising means, first, among the inner periphery 39 of the flat plate portion 31, the stepped portions 35, 35 is provided. The stepped portion 35 of this example protrudes downward from the flat plate portion 31 by the difference between the depth of the low step surface 21 and the plate thickness of the flat plate portion 31 of the opening lid 3, and the surface of the opening lid 3 The surface of the floor panel 1 is flush with the surface. Since the stepped portion 35 is hidden by a carpet or the like attached to the surface of the opening lid 3, the shape or size can be set freely to some extent. However, since the stepped portion 24 that is too wide may drop the carpet or the like that has deteriorated over time, it is desirable to suppress the stepped portion 24 to a width that does not cause the carpet or the like to drop.

また、平板部31の蓋内周辺39のうちパネル外周辺11の延在方向である長辺側には、上記嵩上げ手段として、図３や図６に見られるように、折り返し縁部36を設けている。本例の折り返し縁部36は、前記蓋内周辺39のパネル外周辺11の延在方向である長辺側を、断面円弧状に連続して折り返した縁部であり、低段面21に対する接地安定性を図るほか、上記段押し部35と異なり、蓋内周辺39ぎりぎりまで段差を形成しない構造である。蓋外周辺38をパネル外周辺11に揃えた標準取付状態の開口用蓋３は、低段面21が床パネル１の表面との間に形成する段差部24から、ずらし幅の大きさを隔てて蓋内周辺39のパネル外周辺11の延在方向である長辺側を対向させる。このとき、長辺側に段押し部35同様の構造を採用すると、前記構造が形成する段差がずらし幅以上に離れた位置にできてしまう。確かに、低段面21が存在するため、ハイヒールの踵が落ち込む隙間は形成されないが、低段面21が形成する段差と開口用蓋３が形成する段差とが広がると、経時的に劣化したカーペット等が落ち込んでしまう窪みが形成されることになる。こうした大きな窪みの形成を避けるため、蓋内周辺39のパネル外周辺11の延在方向である長辺側には、できるだけ低段面21が形成する段差に接近する折り返し縁部36にすることが望ましい。 Further, as shown in FIG. 3 and FIG. 6, a folding edge 36 is provided on the long side, which is the extending direction of the outer periphery 11 of the panel, in the inner periphery 39 of the flat plate portion 31 as shown in FIGS. ing. The folded edge 36 of this example is an edge obtained by continuously folding the long side, which is the extending direction of the panel outer periphery 11 of the inner periphery 39 of the lid, in a circular arc shape in cross section, and is grounded to the low step surface 21. In addition to ensuring stability, unlike the step pressing portion 35, the step has a structure in which no step is formed up to the margin of the inner periphery 39 of the lid. The lid 3 for opening in the standard mounting state in which the outer periphery 38 of the lid is aligned with the outer periphery 11 of the panel is separated from the stepped portion 24 formed between the low step surface 21 and the surface of the floor panel 1 by the size of the shift width. Then, the long side which is the extending direction of the panel outer periphery 11 is opposed to the inner periphery 39 of the lid. At this time, if a structure similar to the stepped portion 35 is employed on the long side, the step formed by the structure can be shifted to a position separated by more than the width. Certainly, since there is a low step surface 21, there is no gap in which the heel of the high heel falls, but when the step formed by the low step surface 21 and the step formed by the opening lid 3 spread, it deteriorates over time. A depression into which the carpet or the like falls is formed. In order to avoid the formation of such a large depression, a folded edge 36 that is as close as possible to the step formed by the low step surface 21 should be provided on the long side that is the extending direction of the panel outer periphery 11 of the inner periphery 39 of the lid. desirable.

このほか、本例の開口用蓋３は、平板部31の略中央付近に、パネル外周辺11の延在方向に延びる補強ビード37を段押し形成しており、平板部31に作用する荷重に対する撓みを抑制している。この補強ビード37は、あくまで開口用蓋３自身の補強用であり、大きさ又は形状は自由である。しかし、本例の補強ビード37は、段押し部35や折り返し縁部36と同じ高さにすることにより、補強ビード37の両端を低段面21にまで延長して接地させるようにし、平板部31にかかる荷重を効率的に床パネル１へも伝えられるようにしている。 In addition, the opening lid 3 of this example is formed by pressing a reinforcing bead 37 extending in the extending direction of the outer periphery 11 near the center of the flat plate portion 31, so that the load acting on the flat plate portion 31 can be prevented. Suppression is suppressed. This reinforcing bead 37 is only for reinforcing the opening lid 3 itself, and its size or shape is free. However, the reinforcing bead 37 of the present example has the same height as the step pressing portion 35 and the folded edge portion 36 so that both ends of the reinforcing bead 37 extend to the low step surface 21 and are grounded. The load applied to 31 can be efficiently transmitted to the floor panel 1 as well.

本例の開口用蓋３は、標準位置又は通線位置を選択してコンセントボックス用開口２へ載置でき、しかも補強片部32に通線用凹部34を設けていることで、開口用蓋３を取り除く場合を含めて３通りの通線態様を実現している。更に、同様なコンセントボックス用開口２及び開口用蓋３を設けた床パネル１を組み合わせることで、更に多くの通線態様を実現することができる。 The opening lid 3 of this example can be placed in the outlet box opening 2 by selecting a standard position or a wiring position, and further, by providing the wiring recess 34 in the reinforcing piece 32, the opening lid Three ways of communication are realized including the case of removing three. Furthermore, by combining the floor panel 1 provided with the same outlet box opening 2 and opening lid 3, it is possible to realize many more wiring modes.

通常のフリーアクセス床では、図７に見られるように、床パネル１相互は、コンセントボックス用開口２同士を突き合わせないように、同じ向きに揃えて敷設する。この場合、図８に見られるように、開口用蓋３が標準位置にあれば、通線用凹部34と隣接する床パネル１のパネル外周辺11によって囲まれた小さな通線口４のみが開口する。この小さな通線口４には、例えば直径６mmの同軸ケーブルＣ１が３本通線できるのみである。これに対し、開口用蓋３を通線位置へずらせば、図９に見られるように、開口用蓋３の蓋外周辺38が隣接する床パネル１のパネル外周辺11から離隔し、前記小さな通線口４を含む大きな通線口４が形成される。この大きな通線口４には、直径13mmのテーブルタップ用ケーブルＣ２が２本通せるほか、直径６mmの同軸ケーブルＣ1が前記テーブルタップ用ケーブルＣ2の左右に７本づつ、計14本通線できる。 In a normal free access floor, as shown in FIG. 7, the floor panels 1 are laid in the same direction so that the outlet box openings 2 do not face each other. In this case, as shown in FIG. 8, if the opening lid 3 is in the standard position, only the small passage opening 4 surrounded by the outer periphery 11 of the floor panel 1 adjacent to the passage depression 34 is opened. To do. Only three coaxial cables C1 having a diameter of, for example, 6 mm can be passed through the small passage opening 4. On the other hand, if the opening lid 3 is shifted to the line position, the outer periphery 38 of the opening lid 3 is separated from the outer periphery 11 of the adjacent floor panel 1 as shown in FIG. A large line 4 including the line 4 is formed. In addition to two 13mm diameter table tap cables C2 can be passed through this large wire opening 4, 14mm of coaxial cable C1 with a diameter of 6mm can be routed on the left and right of the table tap cable C2, totaling 14 cables. .

コンセントボックス用開口２同士を突き合わせて床パネル１相互を敷設した場合、次のような通線態様も実現できる。例えば、図10に見られるように、各床パネル１,１それぞれの開口用蓋３,３に設けた通線用凹部34,34が突き合わさり、上記小さな通線口４単独では挿通不可能だったテーブルタップ用ケーブルＣ２を２本挿通できるようになる。また、図11に見られるように、突き合わせた開口用蓋３の一方を通線取付状態にすると、挿通できる同軸ケーブルＣ1は18本まで増やすことができる。更に、図12に見られるように、残る他方の開口用蓋３もずらして通線取付状態にすると、各通線用凹部34,34を除いてもテーブルタップ用ケーブルＣ2の挿通が可能となる上、同軸ケーブルＣ1であれば２列分も挿通できる。この場合、通線用凹部34,34同士を合わせた部分では、テーブルタップ用ケーブルＣ2が２列で挿通できる。 When the floor panel 1 is laid together with the outlet box openings 2 facing each other, the following manner of wiring can also be realized. For example, as shown in FIG. 10, the recesses 34 and 34 provided in the opening lids 3 and 3 of the respective floor panels 1 and 1 face each other, so that the small passage 4 alone cannot be inserted. Two table tap cables C2 can be inserted. Further, as shown in FIG. 11, when one of the butted opening lids 3 is set in a line-attached state, the number of coaxial cables C1 that can be inserted can be increased to 18. Further, as shown in FIG. 12, if the other opening lid 3 is also shifted to be in the through-wire mounting state, the table tap cable C2 can be inserted even if the through-hole recesses 34, 34 are removed. In addition, if the coaxial cable C1, two rows can be inserted. In this case, the table tap cable C2 can be inserted in two rows at the portion where the through-wire recesses 34, 34 are combined.

通線用凹部34は、例えば、図７に見られるように、別段床パネル１のパネル外周辺11に通線用凹部12として形成してもよい。この場合、図13に見られるように、開口用蓋３の通線用凹部34と隣接する床パネル１のパネル外周辺11に形成した通線用凹部12とを突き合わせることで、上述したような通線態様を実現することができる。この場合、床パネル１のパネル外周辺11に形成した通線用凹部12は動かすことができないが、図14に見られるように、開口用蓋３を通線取付状態にすることで、通線口４を拡大することができる。 For example, as shown in FIG. 7, the wire recess 34 may be formed as a wire recess 12 in the outer panel periphery 11 of the separate floor panel 1. In this case, as shown in FIG. 13, as described above, the connection recess 34 of the opening lid 3 and the connection recess 12 formed in the outer panel periphery 11 of the adjacent floor panel 1 are abutted. Can be realized. In this case, although the wiring recess 12 formed in the outer panel periphery 11 of the floor panel 1 cannot be moved, as shown in FIG. The mouth 4 can be enlarged.
