Description

【０００１】
【発明の属する技術分野】
本発明は、左右両側枠間に架設して棚を構成するのに使用される棚板、特に複数枚の帯状単体を並列させると共に隣接する帯状単体どうしを連結具で連結して成る棚板に関するものである。
【０００２】
【従来の技術】
この種の棚板は、例えば特開平１１−６２９１６号公報に記載されたもの（以下、従来構造という）が知られている。この従来構造の棚板では、併用される連結具は、隣接する２つの帯状単体が互いに離間するのを防止することは出来るが、隣接する２つの帯状単体の下方への撓み量が負荷（荷重）の違いで異なるために、両帯状単体間に段差が生じるのを防止することができない。しかもその連結具は、２部品からなるものでコスト高になるばかりでなく、その装着も、棚板構成用の帯状単体をその両端部で互いに連結一体化する前、即ち、帯状単体を並列させるときに同時に連結具を組み付けなければならず、手間がかかる欠点があった。
【０００３】
【課題を解決するための手段】
本発明は上記のような従来の問題点を解消し得る棚板を提供することを目的とするものであって、その手段を後述する実施形態の参照符号を付して示すと、複数枚の帯状単体３を並列させると共に隣接する帯状単体３どうしを連結具１０で連結して成る棚板２であって、各帯状単体３は、天板部４とその左右両側辺から垂下する左右両側板部５、及び天板部４と側板部５との間の角部に沿って形成されたスリット状連結用孔９を備え、連結具１０は、帯状単体３，３間で互いに隣接する２つの前記スリット状連結用孔９に下向きに挿入可能で帯状単体３間で互いに隣接する２枚の前記側板部５を挟む一対の挟持板部１１ａ，１１ｂを備えた倒立Ｕ形板から成るもので、当該一対の挟持板部１１ａ，１１ｂには、互いに隣接する両帯状単体３の天板部４，４の下側に突出する抜け止め部１２ａ，１２ｂが設けられている棚板２において、前記連結具１０の一対の挟持板部１１ａ，１１ｂには、全体が外側へ斜め上向きに直線状に延出する抜け止め用弾性舌片１４が設けられ、各抜け止め用弾性舌片１４の上向き先端が、互いに隣接する両帯状単体３の天板部４下に隣接して、前記抜け止め部１２ａ，１２ｂを構成している。
【０００４】
上記構成の本発明を実施するについて、前記抜け止め用弾性舌片１４は、前記一対の挟持板部１１ａ，１１ｂに形成された門形切込み１３で囲まれた部分を外側へ斜め上向きに折曲させて構成することが出来る。
【０００５】
又、前記スリット状連結用孔９は、帯状単体３の側板部５の外側面位置に達するように形成し、前記連結具１０の上端Ｕターン部１７を、帯状単体３間で互いに隣接する２つのスリット状連結用孔９間に嵌まり込ませて、帯状単体３の天板部４の表面から上方に突出しないように構成するのが望ましい。この構成を採用する場合、前記連結具１０の一対の挟持板部１１ａ，１１ｂは、その中間高さ位置に、帯状単体３間で互いに隣接する２枚の側板部５の全体の板厚Ｔと略同一かそれより狭いくびれ部１５を形成すると共に、当該くびれ部１５から挟持板部１１ａ，１１ｂの先端までの間に先端側ほど広がった導入部１６を形成するように、屈曲させることが出来るし、又、前記一対の挟持板部１１ａ，１１ｂの先端間の間隔は、帯状単体３間で互いに隣接する２枚の側板部５の全体の板厚Ｔより大きいが、帯状単体３間で互いに隣接する２つの前記スリット状連結用孔９の内側辺間の間隔Ｄより小さくすることが出来る。
【０００６】
【発明の実施の形態】
以下に本発明の好適実施形態を添付図に基づいて説明すると、図１は、本発明の棚板で構成される棚の一例を示しており、１Ａ，１Ｂは棚両端の側枠であり、この両側枠１Ａ，１Ｂ間に上下複数断に本発明の棚板２が架設されている。各棚板２の両端の支持方法は、従来周知の手段が採用される。而して、各棚板２は、図２に示すように、並列する複数枚の帯状単体３（図示例では３枚の帯状単体３）から構成される。
【０００７】
各帯状単体３は、図３及び図４に示すように、天板部４とその左右両側辺から垂下する左右両側板部５、当該左右両側板部５の下辺から内向きに延出するリップ部６、両リップ部６の内側辺から天板部４の裏面側に向かって直角に立ち上がる立ち上がり板部７とを備えると共に、前記天板部４には、その長さ方向に連続し且つ天板部４の裏面側に突出するリブ８ａ〜８ｄが形成されたもので、帯状鉄板のロール加工によって一体成形することが出来るものである。前記リブ８ａ〜８ｄとしては、図示のように天板部４の表面から凹入する断面略Ｖ字形のリブを形成することが出来るが、このリブのＶ字形両側壁部を互いに重ね合わせたような、天板部４の表面側から見て凹入する溝状空間を実質的に持たない断面Ｉ型のリブであっても良いし、両側壁部が平行で底部が円弧状の断面Ｕ字形のリブであっても良い。
【０００８】
上記の帯状単体３の天板部４と両側板部５との間の角部には、長さ方向適当間隔おきにスリット状連結用孔９が設けられている。この連結用孔９は、図４Ｂに示すように、帯状単体３の側板部５の外側面位置に達するように形成することにより、当該連結用孔９内に側板部５の切欠き端面５ａを露出させている。図示例では、連結用孔９内に露出する側板部５の切欠き端面５ａが天板部４の裏面より若干下になるように構成しているが、この側板部５の切欠き端面５ａと天板部４の表面との間の段差は、後述する連結具の構成板材の板厚より薄くならないように構成すれば良く、例えば、側板部５の切欠き端面５ａが天板部４の裏面と同一レベルとなるように構成することが出来る。
【０００９】
図２及び図５に示すように、棚板２は、上記の帯状単体３を複数枚（図示例では３枚）並列させて構成するものであるが、このとき、隣り合う２枚の帯状単体３，３が前記連結用孔９を利用して装着される連結具１０によって互いに連結される。この連結具１０は、図６に示すように、一対の挟持板部１１ａ，１１ｂを備えたバネ鋼板製の倒立Ｕ形板から成るもので、当該一対の挟持板部１１ａ，１１ｂには抜け止め部１２ａ，１２ｂが設けられている。
【００１０】
前記連結具１０の抜け止め部１２ａ，１２ｂは、一対の挟持板部１１ａ，１１ｂに形成された門形切込み１３で囲まれた部分を外側へ斜め上向きに折曲させて成る弾性舌片１４から構成されている。而して、一対の挟持板部１１ａ，１１ｂは、図７Ｂに示すように帯状単体３，３間で互いに隣接する２枚の側板部５，５の全体の板厚Ｔと略同一かそれより狭いくびれ部１５を中間高さ位置に形成すると共に、当該くびれ部１５から挟持板部先端までの間に先端側ほど広がった導入部１６を形成するように、左右対称形に屈曲させている。又、一対の挟持板部１１ａ，１１ｂの先端間の間隔は、図７Ｂに示すように帯状単体３，３間で互いに隣接する２枚の側板部５，５の全体の板厚Ｔより大きいが、帯状単体３，３間で互いに隣接する２つの連結用孔９，９の内側辺間の間隔Ｄより小さい。従って、一対の挟持板部１１ａ，１１ｂの先端間の間隔を弾性に抗して狭めたり広げたりすることなく、当該一対の挟持板部１１ａ，１１ｂを、帯状単体３，３間で互いに隣接する２つの連結用孔９，９内に上から振り分け状に容易に挿入することが出来る。又、一対の抜け止め部１２ａ，１２ｂ（弾性舌片１４）の先端間の間隔Ｌは、抜け止めである以上当然であるが、図７Ｂに示すように帯状単体３，３間で互いに隣接する２つの連結用孔９，９の内側辺間の間隔Ｄより大きい。
【００１１】
上記構成の連結具１０は、図８及び図９Ａに示すように、棚板２を構成する各帯状単体３間に於いて互いに隣接する連結用孔９，９に両挟持板部１１ａ，１１ｂを上から挿入するが、その挿入途中で左右一対の弾性舌片１４の外側面が前記連結用孔９，９の側縁（帯状単体３の側板部５に対し内側の側縁）に接することになるので、この段階から連結具１０を下向きに強く押圧して、左右一対の弾性舌片１４を互いに接近する内側へ弾性変形させながら連結具１０を両連結用孔９，９に挿入する。而して、左右一対の弾性舌片１４が完全に両連結用孔９，９から下に入り込んだとき、両弾性舌片１４が外側へ弾性復帰し、連結具１０の装着が完了する。このとき、両弾性舌片１４の先端、即ち、抜け止め部１２ａ，１２ｂが連結用孔９，９の側縁を弾くことになるので、パチンと音がして作業者はその状態、即ち、左右一対の抜け止め部１２ａ，１２ｂが連結用孔９，９の下側に達した連結具装着完了状態を確実に感じ取ることが出来る。
【００１２】
上記のようにして、図８及び図９Ａに示すように、隣り合う両帯状単体３，３間に連結具１０を装着することにより、両帯状単体３，３の互いに隣接する側板部５，５が、連結具１０の一対の挟持板部１１ａ，１１ｂのくびれ部１５で挟まれ、互いに連結される。又、この連結具１０の使用状態に於いて、連結用孔９，９に対して連結具１０が上方に移動することは、両弾性舌片１４の先端、即ち、抜け止め部１２ａ，１２ｂが各帯状単体３，３の天板部４の裏面に当接することにより阻止されるので、連結具１０が上方に抜けて外れる恐れはない。更に、隣り合う両帯状単体３，３の内、一方の帯状単体３が他方の帯状単体３に対して下がるように撓もうとしたとき、図９Ｂに示すように、両抜け止め部１２ａ，１２ｂ（弾性舌片１４）の内、下がろうとする帯状単体３側の抜け止め部１２ａが当該下がろうとする帯状単体３の天板部４の裏面に当接し、この連結具１０自体は、両挟持板部１１ａ，１１ｂを繋ぐ上端Ｕターン部１７が他方の帯状単体３の側板部５の切欠き端面５ａで受止められているので、結局、下がろうとする帯状単体３は連結具１０を介して他方の帯状単体３で受止められ、その下方への撓み変形が阻止され、両帯状単体３，３間に許容限度を超える大きな段差が生じることはない。
【００１３】
棚板２の分解等のために、連結具１０を外す必要が生じたときは、帯状単体３，３の裏側から連結具１０の一対の弾性舌片１４を指先等で弾性に抗して挟み付けて、一対の抜け止め部１２ａ，１２ｂ間の間隔を隣接する連結用孔９，９の内側辺間の間隔Ｄ（図７Ｂ参照）より狭めることにより、両連結用孔９，９から上方へ抜き取ることが出来る。
【００１４】
【発明の効果】
本発明の棚板は以上のように実施し且つ使用することができるものであって、係る本発明の棚板は、並列して当該棚板を構成する帯状単体を互いに隣接するものどうし連結具で連結したものであるが、当該連結具は、帯状単体間で互いに隣接する２つのスリット状連結用孔に一対の挟持板部を上から挿入して隣接する帯状単体間に跨がらせると共に、その抜け止め部を両帯状単体の天板部下側に入り込ませるものであるから、この連結具の装着状態では、隣接する両帯状単体の許容限度を超える上下方向の相対移動を防止出来る。従って、並列する複数枚の帯状単体の内、特定の帯状単体のみに荷重が集中するような状況に於いても、当該帯状単体が隣接する帯状単体よりも大きく下に撓んで段差が生じるというようなことがなくなり、常に平坦な棚板表面を確保することが出来る。
【００１５】
しかも、前記連結具は、帯状単体間で互いに隣接する２つのスリット状連結用孔に一対の挟持板部を上から挿入するものであるから、予め帯状単体を並列させると共にその長さ方向端部を棚受け等を介して支持枠に支持させた状態、即ち、棚板として所定位置に組み込んだ後からでも必要に応じて連結具を組み付け、当該連結具による作用効果を得ることが出来る。
【００１６】
更に本発明の構成によれば、連結具の一対の挟持板部を帯状単体側のスリット状連結用孔に挿入した際、両挟持板部に設けられた抜け止め部、即ち、弾性舌片を前記連結用孔の側辺で容易に弾性変位させて当該連結用孔を容易に通過させることが出来るので、連結具の装着が容易に行える。しかも、連結用孔を通過した抜け止め部、即ち、弾性舌片は、帯状単体の天板部の下側に上向き先端が隣接する斜め上向きの姿勢に弾性復帰し、この姿勢では、連結具の上方への抜け出し移動を強力に阻止出来るので、先に説明した帯状単体間の段差発生を強力且つ確実に防止出来る。更に実施形態に於いて説明したように、弾性舌片が連結用孔を通過したときの弾性復帰時の弾け音で作業者に連結具が所定位置に確実に装着されたことを感覚的に知らしめることが出来、連結具の確実な装着が容易に行える。
【００１７】
尚、請求項２に記載の構成によれば、上記の抜け止め部、即ち、弾性舌片を別部材の取り付けで構成するのではなく、一対の挟持板部に一体に形成することが出来、連結具の大幅なコストダウンを図ることが出来る。
【００１８】
更に、請求項３に記載の構成によれば、連結用孔が天板部の側辺でその側板部より内側に形成されるときのように、連結具装着時に当該連結具の上端Ｕターン部が帯状単体の天板部表面レベルより上に突出させないで済み、棚板表面に突出する連結具の上端Ｕターン部で荷が引っ掛かる不都合を回避出来る。この場合、請求項４に記載の構成によれば、連結具の一対の挟持板部を帯状単体間で隣接する２つのスリット状連結用孔へ挿入することが容易になるにもかかわらず、当該一対の挟持板部のくびれ部で帯状単体間で重なる２枚の側板部を確実に挟ませることが出来、取り付けられた連結具のがたつきを防止出来る。更に、請求項５に記載の構成によれば、連結具の一対の挟持板部を帯状単体間で隣接する２つのスリット状連結用孔へ挿入することが一層容易になる。

In addition, the distance between the tips of the pair of sandwiching plate portions 11a and 11b is larger than the total thickness T of the two side plate portions 5 adjacent to each other between the strip-shaped single bodies 3, but It can be made smaller than the distance D between the inner sides of the two adjacent slit-like connecting holes 9.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a preferred embodiment of the invention will be described with reference to the accompanying drawings. FIG. 1 shows an example of a shelf composed of shelf boards of the invention, 1A and 1B are side frames at both ends of the shelf, The shelf board 2 of the present invention is installed between the both side frames 1A and 1B in a plurality of vertical sections. A conventionally well-known means is employ | adopted for the support method of the both ends of each shelf board 2. FIG. Thus, as shown in FIG. 2, each shelf board 2 is composed of a plurality of strip-shaped single bodies 3 (three strip-shaped single bodies 3 in the illustrated example) arranged in parallel.
[0007]
As shown in FIGS. 3 and 4, each strip-shaped single body 3 includes a top plate portion 4, left and right side plate portions 5 that hang from the left and right sides, and a lip that extends inward from the bottom sides of the left and right side plates 5. And a rising plate portion 7 that rises at right angles from the inner sides of the lip portions 6 toward the back surface side of the top plate portion 4, and the top plate portion 4 is continuous in the length direction and the top plate portion 4. Ribs 8a to 8d projecting on the back side of the plate portion 4 are formed, and can be integrally formed by roll processing of a strip-shaped iron plate. As the ribs 8a to 8d, ribs having a substantially V-shaped cross section that are recessed from the surface of the top plate portion 4 can be formed as shown in the figure, but the V-shaped side walls of the ribs are overlapped with each other. Further, it may be an I-shaped rib having substantially no groove-like space that is recessed when viewed from the surface side of the top plate portion 4, or a U-shaped cross-section in which both side walls are parallel and the bottom is an arc. It may be a rib.
[0008]
In the corner between the top plate portion 4 and the side plate portions 5 of the strip-shaped single body 3, slit-shaped connection holes 9 are provided at appropriate intervals in the length direction. As shown in FIG. 4B, the connection hole 9 is formed so as to reach the outer surface position of the side plate portion 5 of the band-shaped single body 3, whereby the notch end surface 5 a of the side plate portion 5 is formed in the connection hole 9. Exposed. In the illustrated example, the notch end surface 5a of the side plate portion 5 exposed in the coupling hole 9 is configured to be slightly below the back surface of the top plate portion 4, but the notch end surface 5a of the side plate portion 5 and What is necessary is just to comprise so that the level | step difference between the surfaces of the top-plate part 4 may not become thinner than the plate | board thickness of the component board | plate material of the coupling tool mentioned later, for example, the notch end surface 5a of the side-plate part 5 is the back surface of the top-plate part 4. It can be configured to be at the same level.
[0009]
As shown in FIGS. 2 and 5, the shelf board 2 is configured by arranging a plurality of the strip-shaped single bodies 3 (three in the illustrated example) in parallel, but at this time, two adjacent strip-shaped single bodies are formed. 3 and 3 are connected to each other by a connecting tool 10 mounted using the connecting hole 9. As shown in FIG. 6, the connector 10 is composed of an inverted U-shaped plate made of a spring steel plate having a pair of sandwiching plate portions 11 a and 11 b, and the pair of sandwiching plate portions 11 a and 11 b are prevented from coming off. Portions 12a and 12b are provided.
[0010]
The retaining portions 12a and 12b of the connector 10 are formed from an elastic tongue piece 14 formed by bending a portion surrounded by the portal notch 13 formed in the pair of sandwiching plate portions 11a and 11b diagonally upward. It is configured. Thus, as shown in FIG. 7B, the pair of sandwiching plate portions 11a and 11b is substantially the same as or equal to the entire thickness T of the two side plate portions 5 and 5 adjacent to each other between the strip-shaped single bodies 3 and 3. A narrow constricted portion 15 is formed at an intermediate height position, and is bent symmetrically so as to form an introducing portion 16 that extends from the constricted portion 15 to the front end of the holding plate portion. Further, the distance between the tips of the pair of sandwiching plate portions 11a and 11b is larger than the total thickness T of the two side plate portions 5 and 5 adjacent to each other between the strip-shaped single bodies 3 and 3, as shown in FIG. 7B. The distance D is smaller than the distance D between the inner sides of the two connecting holes 9, 9 adjacent to each other between the strip-shaped single bodies 3, 3. Therefore, the pair of sandwiching plate portions 11a and 11b are adjacent to each other between the strip-shaped single bodies 3 and 3 without narrowing or widening the distance between the tips of the pair of sandwiching plate portions 11a and 11b against elasticity. It can be easily inserted into the two connecting holes 9, 9 in a distributed manner from above. Further, the distance L between the tips of the pair of retaining portions 12a and 12b (elastic tongue piece 14) is natural as long as it is retaining, but as shown in FIG. It is larger than the distance D between the inner sides of the two connecting holes 9 and 9.
[0011]
As shown in FIG. 8 and FIG. 9A, the connector 10 having the above-described configuration has both clamping plate portions 11a and 11b in the connecting holes 9 and 9 adjacent to each other between the strip-shaped single bodies 3 constituting the shelf plate 2. Although inserted from above, the outer surfaces of the pair of left and right elastic tongues 14 are in contact with the side edges of the connecting holes 9 and 9 (the side edges on the inner side with respect to the side plate portion 5 of the strip-shaped single body 3) during the insertion. Therefore, from this stage, the connecting tool 10 is strongly pressed downward, and the connecting tool 10 is inserted into the connecting holes 9 and 9 while elastically deforming the pair of left and right elastic tongue pieces 14 toward each other. Thus, when the pair of left and right elastic tongue pieces 14 completely enter the bottom of the connecting holes 9 and 9, both elastic tongue pieces 14 elastically return to the outside, and the attachment of the connector 10 is completed. At this time, since the tips of both elastic tongues 14, that is, the retaining portions 12 a and 12 b repel the side edges of the connection holes 9 and 9, the operator makes a clicking sound, It is possible to reliably sense the state where the pair of left and right retaining portions 12a and 12b reach the lower side of the coupling holes 9 and 9 and the connector is completely attached.
[0012]
As described above, as shown in FIG. 8 and FIG. 9A, the side plate portions 5, 5 adjacent to each other of the belt-like single bodies 3, 3 are mounted by attaching the connecting tool 10 between the belt-like single bodies 3, 3 adjacent to each other. Are sandwiched between the constricted portions 15 of the pair of sandwiching plate portions 11a and 11b of the connector 10, and are connected to each other. In addition, when the connecting tool 10 is in use, the connecting tool 10 moves upward with respect to the connecting holes 9 and 9 because the tips of the elastic tongue pieces 14, that is, the retaining portions 12a and 12b. Since it is blocked by coming into contact with the back surface of the top plate portion 4 of each of the strip-shaped single bodies 3, 3, there is no possibility that the connector 10 comes off upward and comes off. Further, when one of the adjacent belt-like single bodies 3 and 3 is bent so as to be lowered with respect to the other belt-like single body 3, as shown in FIG. 9B, both retaining portions 12a and 12b. Of the elastic tongue piece 14, the retaining portion 12 a on the side of the band-shaped single body 3 to be lowered comes into contact with the back surface of the top plate portion 4 of the band-shaped single body 3 to be lowered, and Since the upper end U-turn portion 17 that connects the holding plate portions 11a and 11b is received by the cut-out end surface 5a of the side plate portion 5 of the other strip-shaped single piece 3, the strip-shaped single piece 3 that is going to be lowered eventually attaches the connector 10. Thus, the other strip-shaped single body 3 is received and the downward bending deformation thereof is prevented, so that a large step exceeding the allowable limit does not occur between the two strip-shaped single bodies 3 and 3.
[0013]
When it is necessary to remove the connector 10 due to the disassembly of the shelf board 2 or the like, the pair of elastic tongues 14 of the connector 10 are sandwiched against the elasticity with fingertips or the like from the back side of the strip-shaped single bodies 3 and 3. In addition, by narrowing the distance between the pair of retaining portions 12a, 12b from the distance D (see FIG. 7B) between the inner sides of the adjacent connection holes 9, 9, upward from both connection holes 9, 9.

【The invention's effect】
The shelf board of the present invention can be implemented and used as described above, and the shelf board of the present invention is such that the strips constituting the shelf board in parallel are adjacent to each other. The connecting tool is inserted between a pair of sandwiching plate portions from above the two slit-shaped connecting holes adjacent to each other between the strip-shaped single pieces and straddles between the adjacent strip-shaped single pieces, Since the retaining portion enters the lower side of the top plate portion of both belt-like single bodies, in the mounted state of this connector, relative movement in the vertical direction exceeding the allowable limit of the adjacent belt-like single bodies can be prevented. Therefore, even in a situation where the load is concentrated only on a specific strip-shaped single piece among a plurality of strip-shaped single pieces arranged in parallel, the band-shaped single piece is bent downward greatly than the adjacent strip-shaped single piece, resulting in a step. It is possible to always ensure a flat shelf surface.
[0015]
And since the said connector inserts a pair of clamping board part from the top to the two slit-shaped connection holes mutually adjacent between strip | belt-shaped single units | sets, while arranging a strip | belt-shaped single unit beforehand and its length direction edge part As a result, the coupling tool can be assembled as needed even after the rack is supported on the support frame via a shelf holder or the like, that is, after being assembled at a predetermined position as a shelf board.
[0016]
Furthermore , according to the configuration of the present invention , when the pair of sandwiching plate portions of the coupling tool are inserted into the slit-shaped coupling holes on the belt-like single body side, the retaining portions provided on both sandwiching plate portions, that is, the elastic tongue pieces are Since it can be easily elastically displaced at the side of the connecting hole and can easily pass through the connecting hole, the connecting tool can be easily mounted. In addition, the retaining portion that has passed through the coupling hole, that is, the elastic tongue piece, elastically returns to an obliquely upward posture in which the upward tip is adjacent to the lower side of the top plate portion of the band-shaped unit. Since it is possible to strongly prevent upward movement, it is possible to strongly and reliably prevent the occurrence of a step between the belt-like single members described above. Further, as described in the embodiment, the operator knows sensuously that the coupling tool is securely mounted at a predetermined position by the elastic sound when the elastic tongue piece passes through the coupling hole. It can be tightened, and the fitting of the connecting tool can be easily performed.
[0017]
In addition, according to the structure of Claim 2 , it can form integrally in a pair of clamping board part instead of comprising said retaining part, ie, an elastic tongue piece by attachment of another member, The cost of the coupler can be greatly reduced.
[0018]
Furthermore, according to the configuration of claim 3 , the upper end U-turn portion of the connector is mounted when the connector is mounted, such as when the connection hole is formed on the side of the top plate portion and on the inner side of the side plate portion. However, it is not necessary to protrude above the surface level of the top plate portion of the single belt-like member, and the inconvenience that the load is caught at the upper end U-turn portion of the connector protruding on the shelf plate surface can be avoided. In this case, according to the configuration described in claim 4 , although it becomes easy to insert the pair of sandwiching plate portions of the coupler into the two slit-shaped coupling holes adjacent between the strip-shaped single pieces, The two side plate portions that overlap between the belt-like single pieces can be reliably sandwiched by the constricted portions of the pair of sandwich plate portions, and rattling of the attached connecting tool can be prevented. Furthermore, according to the structure of Claim 5 , it becomes easier to insert a pair of clamping board part of a connector into the two slit-shaped connection holes adjacent between strip | belt-shaped single_piece | units.
