- the concave step portion 26 that is recessed toward the inner side in the width direction is formed on the entire length of the cross beam portion 25 on the outer surface in the width direction of the cross beam portion 25 of the leg 20. Since the optional member mounting seat 12 is provided at the bottom of the concave step portion 26 and the concave step portion 26 is detachably closed by the cover member 27, the outer side of the leg 20 in the width direction is formed.
- the concave step portion 26 of the cross beam portion 25 is closed by the cover member 27, so that the mounting seat 12 and the like in the concave step portion 26 are exposed to the outside, and the quality of the appearance of the desk device 1.
- the desk device 1 can attach the optional member to the mounting seat 12 in the concave step portion 26 by removing the cover member 27 from the concave step portion 26 of the transverse beam portion 25. Therefore, in this desk device 1, an optional member can be added to the outer surface of the leg 20 as needed without causing deterioration in the quality of the appearance.

Description
本願は、2012年9月28日に、日本に出願された特願2012-218665号および特願2012-218667号に基づき優先権を主張し、その内容をここに援用する。
この種のデスク装置の脚体としては、床面上に沿わせて横向きに載置される下部パイプと、下部パイプの一端部若しくは中央部から上方に向かって延びる縦パイプと、縦パイプの上端部から下部パイプと平行に延びる上部パイプとにより、側面視がU字状をなすように形成されたタイプ(いわゆるL型脚)や、側面視がH字状をなすように形成されたタイプ(いわゆるT型脚)が多く見られる。また、パイプ材以外からなる脚体としては、パネル状のタイプも多く見られる。
ただし、このデスク装置の構造は、棒状の脚体のみによって天板ユニットを支持していることから、デスク装置の側方からの外力に対する強度的な面で不安がある。
これにより、脚部の横梁部の外側面にオプション部材を取り付けない場合には、凹状段部をカバー部材で閉塞しておき、オプション部材を取り付ける場合には、カバー部材を取り外し、凹状段部内の取付座を通してオプション部材を横梁部の外側面に取り付けることが可能になる。
これにより、凹状段部に取り付けられたカバー部材が横梁部の下端から下方に露出しなくなり、カバー部材が脱落したり、損傷したりしにくくなる。
これにより、凹状段部内の溶接部は、凹状段部にカバー部材が取り付けられることにより、外部から隠されることになり、デスク装置としての体裁を良好にすることができる。
この発明の場合、天板の幅方向の外側端面にオプション部材を追加するときには、ブラケットを、脚固定壁部分で横梁部の幅方向の外側面に取り付け、オプション部材を天板の幅方向の外側端面に突き合わせた状態において、ブラケットのオプション固定壁にオプション部材を支持固定する。
これにより、横梁部上のブラケットの取付部が天板の下方の幅方向の内側に位置され、外観の低下が回避される。
これにより、横梁部にオプション部材を取り付けない場合にも、ブラケットの取付座を覆うカバー部材が天板の下方で幅方向の外側に突出しなくなり、外観の低下が回避される。また、天板の幅方向の端面を別のデスク装置の天板や壁等に近接させて配置する場合に、天板と他のデスク装置や壁等との間に隙間が生じることがなくなる。
これにより、ブラケットにオプション部材の大きな重量が加わった場合におけるオプション部材の幅方向外側が下方に傾斜するのを未然に防止することができる。
なお、以下の説明においては、床面Fと直角な方向を上下方向と呼び、天板ユニット100の長尺な方向(長手方向)を幅方向、天板ユニット100の短尺な方向を奥行方向と呼び、図中LH,RHを結ぶ矢印は幅方向を指し、図中FR,RRを結ぶ矢印は奥行方向を指す。奥行方向は、後述する脚体20の横梁部25が延びる方向と一致する方向である。幅方向は、上下方向と奥行方向に対して直交する方向である。また、以下で説明する各実施形態においては、同一部分に同一符号を付して重複する説明を省略する。
図1~図3に示すように、天板ユニット100は、平面視が矩形状の4枚の天板部材2a,2b,2c,2dを有している。天板部材2a,2b,2c,2dは、各2枚の天板部材2a,2b、及び、2c,2dが長手方向の端面を突き合せて一定の奥行幅の連続した机上面を形成している。これらの連続した机上面を形成する2組の天板部材の対2A,2B(以下、「天板2A,2B」と呼ぶ。)が奥行方向の中央に離間スペース3を挟んで対向して配置されている。天板2A,2Bは、長尺な辺が相互に平行に対向配置され、奥行方向の中央の離間スペース3は幅方向に沿って連続している。
なお、この実施形態においては、各天板2A,2Bが2枚の天板部材2a,2b、及び、2c,2dによって構成されているが、それぞれ連続した一枚板によって構成することも可能である。
横梁部25は、プレス成形された2枚の金属プレートが組み合わされ、その主要部が筒状に形成されている。横梁部25の長手方向の両端部は、脚本体部24,24の各上部側面に溶接固定されている。こうして、2本の脚本体部24,24の上部に横梁部25が連結された脚体20は、幅方向から見た側面視が門型状(開口側が下方を向くU字形状)となっている。
脚体20の横梁部25の主要部は、図5に示すように、奥行方向に長尺な金属製の第1プレート25Aと第2プレート25Bとによって形成されている。第1プレート25Aと第2プレート25Bはプレス成形によって屈曲して造形され、両者が相互に溶接されて閉(中空)断面とされている。横梁部25の幅方向の外側面には、奥行方向に沿って延びる凹状段部26が形成されている。凹状段部26は、横梁部25の外側面の高さ方向のほぼ中央に配置され、同断面形状が横梁部25の全長に亘って連続している。
したがって、凹状段部26は、横梁部25の下端から上方に離間した位置に形成されている。
また、横梁部25の端部は、上述のように脚本体部24の上部側面に突き合わせられて溶接固定されるが、脚本体部24に対する横梁部25の幅方向外側での溶接個所は、図4中の符号w1,w2,w3で示すように凹状段部26の内側領域に設定されている。
各支持アーム28,29は、図6~図11に示すように、上向きに開口する略U字状の連結杆保持部28a,29aと、横梁部25の頂部面25aと同一高さ位置で略水平に延び天板2A,2Bの下面を支持する天板支持壁28b,29bと、を備えている。
内側連結杆31を保持する支持アーム29は、端面が横梁部25の段差部32の縦壁32bに突き当てられるとともに、連結杆保持部29aの下面(幅方向に沿う面)が段差部32の底面32aに突き当てられ、これらの突き当てられた部分が相互に溶接固定されている。
また、外側連結杆30を保持する支持アーム28は、奥行方向外側の端部が略直角に下方に折り曲げられた折り曲げ部28cを備え、全体の端面が横梁部25の段差部32の縦壁32bに突き当てられるとともに、図7,図9に示すように、折り曲げ部28cの奥行方向外側の側面(幅方向に沿う面)が段差部32の側端部に臨む脚本体部24の内側側面に突き当てられ、これらの突き当てられた部分が相互に溶接固定されている。
各スペーサ部材41は、横梁部25のうちの支持アーム28,28,29,29が取り付けられる部位、つまり、外側連結杆30の連結部の延長上位置と、内側連結杆31の連結部の延長上位置とに配置されている。なお、図11においては、図示の都合上、支持アーム29を取り去った状態で横梁部25を示している。
なお、図1,図2中の符号39は、奥行方向前後の配線カバー38,38の間の隙間を埋める目隠し部材である。
図1,図12,図13に示すキャビネット47は、天板2A,2Bの幅方向の外側端面に突き当てられる底板47aを有し、その底板47aの上面の奥行方向の両端と中央とに、一対の側板47b,47bと仕切板47cとが立設されるとともに、底板47aの上面の幅方向の外側端部に背板47dが立設され、これらの側板47b,47bと仕切板47cと背板47dの上部が上板47eによって閉じられている。キャビネット47の底板47aは、天板2A,2Bと同厚みに形成されている。底板47aは、天板2A,2Bの幅方向の外側端面と突き合わせて設置されることにより、その上面が天板2A,2Bの上面と連続する物品載置面とされる。底板47a上には、ファイルfや書類等を収納できる。
ブラケット45は、横梁部25の凹状段部26内の取付座12に取り付けられた状態において、オプション固定フランジ52の上面が幅方向の外側に向かって微小角度α分だけ上方に傾斜して形成されている。
なお、横梁部25にキャビネット47等のオプション部材を取り付けないときには、横梁部25からブラケット45が取り外されて凹状段部26がカバー部材27によって閉じられるが、カバー部材27は、前述のように凹状段部26に取り付けられた状態において、外側面(外側露出面)が横梁部25の幅方向の外側面と面一になるように設定されているため、凹状段部26に取り付けられたカバー部材27は天板2A,2Bの幅方向の外側端面よりも内側に配置されることになる。
一方、デスク装置1は、オプション部材を取り付ける場合には、横梁部25の凹状段部26からカバー部材27を取り外すことにより、オプション部材を凹状段部26内の取付座12に取り付けることができる。
したがって、このデスク装置1においては、外観の品質の低下を招くことなく、必要に応じて脚体20の外側面にオプション部材を追加することができる。
したがって、このデスク装置1においては、追加するオプション部材が重量物であっても、オプション部材を脚体20に安定的にかつ強固に取り付けることができる。
