Description

本発明は、天板の横揺れに善処したテーブルに関するものである。 The present invention relates to a table that is well-treated against rolling of a top board.

テーブルは、天板の四隅下面を脚柱に支持させて構成されるものが一般的であり、強度を高めるために、様々な工夫を凝らしたものが提案されている。 Tables are generally constructed by supporting the bottom surfaces of the four corners of the top plate with pedestals, and various devices have been proposed to increase the strength.

例えば、特許文献１には、横桟及び天板用の支持ブラケットの脚への取付強度を高めることにより、天板を安定して強固に支持し、加工・組立て工数およびコストを低減したテーブルを提供すべく、断面Ｌ字形の支持ブラケットの上板部を脚の上端面に固定するとともに、上板部から垂下する側板部を、前脚の側面と、横桟の両面との間に挟んで、それらをねじにより固定して、支持ブラケットを脚に固定し、上板部上に天板を取付けるようにした構造が開示されている。横桟間は前後一対の連結杆によって連結されている。 For example, Patent Document 1 discloses a table that stably and firmly supports the top plate by increasing the mounting strength to the legs of the support brackets for the horizontal rail and the top plate, and reduces the processing and assembly man-hours and costs. In order to provide, while fixing the upper plate portion of the L-shaped support bracket to the upper end surface of the leg, the side plate portion hanging from the upper plate portion is sandwiched between the side surface of the front leg and both sides of the horizontal rail, A structure is disclosed in which they are fixed with screws, the support bracket is fixed to the legs, and the top plate is mounted on the upper plate portion. The cross rails are connected by a pair of front and rear connecting rods.

ところが、かかる特許文献１のものは、横桟に対する脚の取付強度を高めることはできても、天板や連結杆それ自体の剛性を高めるものではない。このため、天板や連結杆の剛性に起因して生じる横揺れを防止する手立てにはなり難い。 However, although the thing of this patent document 1 can raise the attachment intensity | strength of the leg with respect to a crosspiece, it does not raise the rigidity of a top plate or a connecting rod itself. For this reason, it is difficult to provide a means for preventing rolls caused by the rigidity of the top plate and the connecting rod.

すなわち、所定方向に離間する一対の端部脚の間が天板を介して直接又は間接に連結されるこの種のテーブルにおいては、脚周辺の強度を高めて天板を安定して強固に支持したつもりでも、使用中に天板中央部が横揺れする現象が現れることがある。近時のフリーアドレスタイプのテーブル等では一対の端部脚の間が広く、天板に幅広な大型天板が用いられる傾向にあり、脚周辺部での歪みのほかに、天板や横架材の撓み等に起因した振動も無視できない。例えば、天板上で消しゴムを使用すると、その周期が天板や横架材の持つ固有振動数に共振した場合等に、普段では現れない横揺れ現象が健在化することがある。このため、脚周辺の取付強度を高めるだけでは、横揺れ対策としては不十分である。 In other words, in this type of table where a pair of end legs spaced apart in a predetermined direction are connected directly or indirectly via a top plate, the strength of the periphery of the legs is increased to support the top plate stably and firmly. Even if you intend to do so, you may experience a phenomenon that the center of the top plate rolls during use. In recent free address type tables, etc., there is a tendency to use a wide, large top plate between the pair of end legs and the top plate. Vibrations caused by bending of the material cannot be ignored. For example, when an eraser is used on the top plate, a roll phenomenon that does not normally appear may become alive when the period resonates with the natural frequency of the top plate or the horizontal member. For this reason, simply increasing the mounting strength around the legs is not sufficient as a measure against rolling.

本発明は、このようにテーブルに内在する課題を新たに知見することによりなされたものであって、天板や横架材、端部脚等の構造躯体を重厚で過剰品質とすることなく、天板の横揺れに適切に善処した新たなテーブルを提供することを目的としている。 The present invention was made by newly finding out the problems inherent in the table in this way, and without making the structural housing such as the top plate, the horizontal member, and the end legs heavy and excessive quality, The purpose is to provide a new table that is properly treated against the rolling of the top board.

本発明は、かかる目的を達成するために、次のような手段を講じたものである。 In order to achieve this object, the present invention takes the following measures.

すなわち、本発明のテーブルは、所定方向に離間する一対の端部脚の間が天板を介して直接又は間接に連結されるものにおいて、前記端部脚よりも内側へ離れた位置に、天板を直接又は間接に支持すべく少なくとも２つの中間脚要素を前記所定方向に沿って配置し、これら２つの中間脚要素の上端部間およびそれよりも下部間を上補強連結部と下補強連結部で連結してなることを特徴とする。 That is, the table of the present invention is such that a pair of end legs spaced apart in a predetermined direction are connected directly or indirectly via a top plate, and the table is located at a position farther inward than the end legs. In order to directly or indirectly support the plate, at least two intermediate leg elements are arranged along the predetermined direction, and the upper reinforcing connection part and the lower reinforcing connection are provided between the upper ends of these two intermediate leg elements and the lower part thereof. It connects with a part, It is characterized by the above-mentioned.

中間脚要素は天板側への接続点に近い付け根が相互に連結されるだけでなく、付け根から遠い位置が下補強連結部によっても相互に連結されるため、中間脚要素の付け根に過大な倒れモーメント荷重が集中することを回避することができる。中間脚要素を取り付けた場合、天板の横揺れには中間脚要素の倒れが伴うが、このように中間脚要素の倒れを抑える結果、天板の横揺れに対する強度を有効に高めることができる。そして、単に２つの中間脚要素を追加して相互に上下の補強連結部で連結するだけであるから、構造躯体となる中間脚を抜本的に重厚とすることなく、天板の横揺れに簡易に対応することが可能となる。 In the intermediate leg element, not only the bases close to the connection point to the top plate side are connected to each other, but also the position far from the base is also connected to each other by the lower reinforcing connection part. Concentration of the falling moment load can be avoided. When the intermediate leg element is attached, the roll of the top plate is accompanied by the fall of the intermediate leg element. As a result of suppressing the fall of the intermediate leg element in this way, the strength against the roll of the top plate can be effectively increased. . And, simply by adding two intermediate leg elements and connecting them with the upper and lower reinforcement connecting portions, it is easy to roll the top plate without drastically thickening the intermediate legs as the structural frame. It becomes possible to cope with.

ここで、中間脚要素とは、脚支柱のように独立した脚の形態をなしているものに限らず、上からの圧縮強度を増すような構造を備えているもの全般を言う。例えば、板材の曲げ加工部分、しぼり加工部分、補強材の取付部分などによって圧縮強度を高める構造を備えた部分は、本発明の中間脚要素たり得る。したがって、中間脚要素に対して上補強連結部や下補強連結部は一体として構成されても別体として構成されて接続されても構わない。 Here, the intermediate leg element is not limited to an independent leg form such as a leg column, and refers to an element having a structure that increases the compressive strength from above. For example, a portion provided with a structure that increases the compressive strength by a bent portion, a squeezed portion, a reinforcing member attachment portion, or the like of the plate material may be the intermediate leg element of the present invention. Therefore, the upper reinforcing connecting portion and the lower reinforcing connecting portion may be configured as a single body or may be configured separately and connected to the intermediate leg element.

一致の中間脚要素の倒れに対して高い強度を実現するためには、下補強連結部は、一方の中間脚要素の上端部側と他方の中間脚要素の下端部側との間を連結するものが好ましい。 In order to achieve high strength against the falling of the matching intermediate leg element, the lower reinforcing connecting portion connects between the upper end side of one intermediate leg element and the lower end side of the other intermediate leg element. Those are preferred.

一層の強度向上とともに、中間脚要素の間の隙間を埋める化粧材としても利用するためには、下補強連結部は、一対の中間脚要素の間を連結する面板部を具備することが望ましい。 In order to further improve the strength and use it as a decorative material that fills the gap between the intermediate leg elements, it is desirable that the lower reinforcing connecting portion includes a face plate portion that connects the pair of intermediate leg elements.

横架材の剛性を高めることで横揺れを抑えるためには、一対の端部脚の間を横架材で連結して脚体を構成し、この脚体に天板を支持させてなるものであって、中間脚要素の間を連結する上補強連結部が前記横架材を含んで構成されることが適当である。 In order to suppress the roll by increasing the rigidity of the horizontal member, a leg is constructed by connecting a pair of end legs with a horizontal member, and the top plate is supported by this leg In this case, it is appropriate that the upper reinforcing connecting portion for connecting the intermediate leg elements includes the horizontal member.

一対の端部脚の間を複数の横架材で連結して脚体を構成し、この脚体に天板を支持させてなるテーブルにおいて、中間脚要素の倒れ剛性を有効に高め、脚受け部材にも制振作用を営ませるためには、前記複数の横架材の間を脚受け部材で接続し、中間脚要素の間を連結する上補強連結部が前記脚受け部材を含んで構成されることが好ましい。 A leg is constructed by connecting a pair of end legs with a plurality of horizontal members, and in a table in which the top plate is supported by the leg, the falling rigidity of the intermediate leg element is effectively increased, and the leg rest In order to make the member also have a damping action, the plurality of horizontal members are connected by leg support members, and an upper reinforcing connecting portion for connecting intermediate leg elements includes the leg support members. It is preferred that

一対の端部脚の間を天板で直接連結してなるテーブルにおいて、天板の剛性を高めることで横揺れを抑えるためには、中間脚要素の間を連結する上補強連結部が前記天板を含んで構成されることが望ましい。 In a table in which a pair of end legs are directly connected by a top plate, in order to suppress rolling by increasing the rigidity of the top plate, an upper reinforcing connecting portion that connects between intermediate leg elements is the top plate. It is desirable to include a plate.

テーブルに対面で着座した場合に中間脚要素が下肢空間の利用の妨げなることを適切に防止するためには、前記所定方向と直交する方向に、対面で使用可能な一対の天板が所定の隙間を介して配置され、中間脚要素はそれら天板間の隙間の下方に配置されていることが好ましい。 In order to appropriately prevent the intermediate leg element from interfering with the use of the lower limb space when sitting on the table facing each other, a pair of top plates that can be used facing each other in a direction orthogonal to the predetermined direction It is preferable that the intermediate leg elements are arranged below the gap between the top plates.

勿論、前記所定方向と直交する方向に、対面で使用可能な一対の天板領域が設定されている場合に、中間脚要素をそれら天板領域間の境界部の下方に配置しても同様の効果が奏される。 Of course, when a pair of top plate areas that can be used facing each other are set in a direction perpendicular to the predetermined direction, the same thing can be done even if the intermediate leg element is arranged below the boundary between the top plate areas. An effect is produced.

本発明は、以上説明したように、少なくとも一対の中間脚要素を端部脚の離間方向に沿って天板を支持するように配置し、上下の補強連結部で中間脚要素相互の倒れを拘束するようにしたので、中間脚要素の付け根に過大な倒れモーメント荷重が集中することを回避して中間脚要素を倒れ難い構造にし、ひいてはこの中間脚要素に支持された天板が中間脚要素の倒れとともに横揺れする現象を防止して、簡易な構成でテーブルの使用感を飛躍的に向上させることが可能となる。 In the present invention, as described above, at least a pair of intermediate leg elements are arranged so as to support the top plate along the separation direction of the end legs, and the upper and lower reinforcing connection parts restrain the fall of the intermediate leg elements from each other. Therefore, the intermediate leg element is prevented from concentrating at the base of the intermediate leg element, and the intermediate leg element is structured to be difficult to fall down. It is possible to prevent the phenomenon of rolling with falling, and to dramatically improve the feeling of use of the table with a simple configuration.

The joint material 15 is in the form of a block, and a fitting portion 15a protrudes toward the end portion 14a of the horizontal member 14, and this fitting portion 15a is fitted to the end portion 14a of the horizontal member 14, The joint material 15 is attached to the end portion 14a of the horizontal member 14 by a pin 161 that penetrates the horizontal member 14 and the fitting portion 15a simultaneously. In the figure, reference numeral 162 denotes a C-ring for preventing the pin 161 from coming off. An eave-like protrusion 15b that rides on the upward surface 13b of the horizontal rail 13 is provided at a portion of the joint material 15 opposite to the fitting portion 15a, and the top plate set on the upper surface 15c of the joint material 15 The support surface 151 is disposed at a position higher than the upward surface 13b of the horizontal rail 13 by the thickness 15bX of the protrusion 15b. Then, the joint material 15 is connected to the horizontal beam 13 via the horizontal bolt 163 in a state where the vertical surface 15c of the joint material 15 is abutted against the vertical surface 13a of the horizontal beam 13, and the joint material 15 of the joint material 15 is connected in this state. With respect to the top plate 2 placed on the top plate support surface 151, the lower surface 2 b of the top plate 2 is drawn to the joint material 15 via a bolt 164 in the vertical direction and connected. An adjuster 17 is provided at the lower end 12 a of the front and rear columns 12 that constitute the end leg 11.

天板２は、図１、図３、図４等に示すように、天板幅方向Ｘと直交する奥行き方向Ｙに所定の隙間Ａを隔てて対をなして配置され、各天板２は、各々対応する２本の横架材１４の各ジョイント材１５に固定されている。図２及び図５等に示すように、横架材１４の上面１４ｂはジョイント材１５の上面１５ｃと同一高さ位置にあり、ジョイント材１５の上面１５ｃとともに天板支持面１４１、１５１を構成している。 As shown in FIGS. 1, 3, 4, etc., the top plates 2 are arranged in pairs in a depth direction Y orthogonal to the top plate width direction X with a predetermined gap A therebetween. These are fixed to the joint members 15 of the two corresponding horizontal members 14. As shown in FIGS. 2 and 5, the upper surface 14 b of the horizontal member 14 is at the same height as the upper surface 15 c of the joint material 15, and constitutes the top plate support surfaces 141 and 151 together with the upper surface 15 c of the joint material 15. ing.

この状態で、図４及び図５等に示すように、横架材１４は端部脚１１を構成する横桟１３の上下寸法１３Ｙ内にほぼ位置し、特に横架材１４の下面１４ｃは横桟１３の下面１３ｃよりも下方に突出していない。また、横架材１４は、図４等に示すように天板２の使用縁２ａの近くには位置していない。したがって、図１における天板幅方向Ｘに沿って対向する一対の使用縁２ａの何れの位置にも、下肢空間Ｚが最大に確保され、着席者の移動やワゴンの挿脱を天板幅方向Ｘに自由に行えるフリーアドレスタイプのテーブルＴを構成している。天板幅寸法２Ｘは、通常単独で使用される天板幅寸法２Ｘの２倍以上に設定されており、天板２は天板幅方向Ｘに沿って端部脚１１と端部脚１１の間が一枚もので構成されていて、この実施形態では幅方向中間位置Ｘ１に天板受け部材などは存していない。 In this state, as shown in FIG. 4 and FIG. 5 and the like, the horizontal member 14 is substantially located within the vertical dimension 13Y of the horizontal beam 13 constituting the end leg 11, and in particular, the lower surface 14c of the horizontal member 14 is It does not protrude below the lower surface 13 c of the crosspiece 13. Moreover, the horizontal member 14 is not located near the use edge 2a of the top plate 2 as shown in FIG. Therefore, the lower limb space Z is secured at the maximum in any position of the pair of use edges 2a facing along the top plate width direction X in FIG. 1, and the movement of the seated person and the insertion / removal of the wagon can be performed in the top plate width direction. A free address type table T that can be freely set in X is configured. The top board width dimension 2X is set to be twice or more of the top board width dimension 2X that is normally used alone, and the top board 2 extends along the top board width direction X between the end legs 11 and the end legs 11. In this embodiment, there is no top plate receiving member at the intermediate position X1 in the width direction.

そして本実施形態は、図１、図２等に示すように、前記端部脚１１よりも内側すなわち天板中央部２１側へ離れた位置において、それら天板２、２間の隙間Ａの下方に、天板２を支持すべく少なくとも２つの中間脚要素３１、３１を天板幅方向Ｘに沿って配置し、これら２つの中間脚要素３１、３１の上端部間３１Ｚおよびそれよりも下部間３ｂを上補強連結部３２と下補強連結部３３で連結している。すなわち、中間脚要素３１と端部脚１１とは相互に直接接続されることはなく、独立している。 In this embodiment, as shown in FIGS. 1 and 2, etc., below the gap A between the top plates 2 and 2 at a position inside the end legs 11, that is, away from the end plate 11 toward the center portion 21 side.

中間脚要素３１、３１は、スチール板を用いて構成されるもので、図７等に示すように、面板部３ｐの両側縁３ｐａを角パイプ状に折り曲げることによって両側に中間脚要素３１、３１を形成するとともに、これら中間脚要素３１、３１の間３１Ｘの凹み部分３１１を、面板部３ｑの周囲を折り曲げた扁平箱状の蓋材３２で閉止して扁平な直方体状をなす中間脚３を構成している。蓋材３２と中間脚要素３１、３１との間は溶接等により連結されている。すなわち、これらの面板部３ｐ、３ｑは、一対の中間脚要素３１、３１の間３１Ｘを連結する下補強連結部３３としての役割を担っている。この実施形態における中間脚要素３１、３１は、脚支柱のように独立した脚の形態をなしているものではないが、上からの圧縮強度を増す脚としての機能を発揮する点で、脚の概念に含まれるものである。この意味で、中間脚要素３１、３１は、本実施形態のような板材の曲げ加工部分以外に、例えばしぼり加工部分、補強材の取付部分などのように、圧縮強度を高める対策を施した種々の態様が含まれる。 The intermediate leg elements 31 and 31 are configured using steel plates. As shown in FIG. 7 and the like, the intermediate leg elements 31 and 31 are formed on both sides by bending both side edges 3pa of the face plate portion 3p into a square pipe shape. The intermediate leg 3 having a flat rectangular parallelepiped shape is formed by closing the recessed portion 311 of 31X between the intermediate leg elements 31 and 31 with a flat box-shaped lid member 32 bent around the face plate portion 3q. It is composed. The lid member 32 and the intermediate leg elements 31, 31 are connected by welding or the like. That is, these face plate portions 3p, 3q serve as a lower reinforcing connecting portion 33 that connects 31X between the pair of intermediate leg elements 31, 31. The intermediate leg elements 31 and 31 in this embodiment are not in the form of independent legs like the leg struts, but the leg functions in that the leg functions to increase the compression strength from above. It is included in the concept. In this sense, the intermediate leg elements 31 and 31 have various measures to increase the compressive strength, such as a squeezed portion and a reinforcing material mounting portion, in addition to the bent portion of the plate material as in the present embodiment. Embodiments are included.

The bracket 34 is inserted into the hollow portion 41 of the channel-shaped leg receiving member 4 that opens downward, and a joint member 43 such as a weld joint as shown in FIG. 6 is formed on the lower surface 42a of the upper wall 42 that becomes the groove bottom 421. It is joined via. The leg receiving member 4 is formed by bending an iron plate, and has a flange portion 44 having a hat-like cross section as shown in FIG. 7 in a part thereof, and a direction orthogonal to the bending direction on the upper surface 42b of the upper wall 42. A gap closing member 5 having a hat-shaped cross section having protrusions 51 is superposed. The outer dimension 4Y of the standing wall 45 of the leg receiving member 4 substantially corresponds to the inner dimension 14Y of the horizontal members 14 and 14 located on both sides of the central portion of the top plate 2 in the depth direction. And in the state where the ridge 51 of the gap closing member 5 is inserted into the gap A between the pair of top plates 2, 2, the standing wall 45 of the leg receiving member 4 is inserted between the nearest horizontal members 14, 14, In this state, the flange portion 44 is brought into contact with the lower surface 14 c of the horizontal member 14, and the leg receiving member 4 is fastened and fixed to the horizontal member 14 by a bolt 46 penetrating the flange portion 44. As described above, the leg receiving member 4 connects between the horizontal members 14 and 14, and the upper end portion 31 a of the intermediate leg 3 including both the intermediate leg elements 31 and 31 is attached to the leg receiving member 4. Accordingly, the leg receiving member 4 constitutes an upper reinforcing connecting portion 32 that connects the upper end portions 31Z of the pair of intermediate leg elements 31, 31.

この中間脚要素３１、３１の下端部３１ｂにも、それぞれ図２等に示すようにアジャスタ３７が設けてあり、所定取付位置でアジャスタ３７が適切に接地する状態に調節して、テーブルＴへの中間脚の後付け作業が完了する。 The lower end 31b of each of the intermediate leg elements 31 and 31 is also provided with an adjuster 37 as shown in FIG. 2 and the like, and the adjuster 37 is adjusted to be properly grounded at a predetermined mounting position. The retrofit of the intermediate leg is completed.

前記天板２，２間の隙間Ａは、床からの配線を立ち上げる配線取出口としての利用が可能であり、前記脚受け部材４の一部に形成した取付片４ｐ（図７参照）は、前記隙間Ａの下方に図示しない配線ダクトを配置する際の取付先として適宜利用することが可能なものである。 The gap A between the top plates 2 and 2 can be used as a wiring outlet for raising the wiring from the floor, and an attachment piece 4p (see FIG. 7) formed on a part of the leg receiving member 4 The wiring duct (not shown) can be appropriately used as an attachment point when the wiring duct (not shown) is disposed below the gap A.

以上のように構成される本実施形態のテーブルＴは、天板幅方向Ｘに離間する一対の端部脚１１の間が天板２を介して間接的に連結されるものであり、前記端部脚１１よりも内側へ離れた位置に、天板２を間接的に支持すべく少なくとも２つの中間脚要素３１、３１を所定方向である天板幅方向Ｘに沿って配置し、これら２つの中間脚要素３１、３１の上端部間３１Ｚおよびそれよりも下部間３ｂを上補強連結部３２と下補強連結部３３で連結したものである。 The table T of the present embodiment configured as described above is configured such that the pair of end legs 11 that are separated in the top plate width direction X are indirectly connected via the top plate 2. At least two intermediate leg elements 31, 31 are arranged along a top plate width direction X, which is a predetermined direction, to indirectly support the top plate 2 at positions farther inward than the base legs 11. The upper leg connecting portion 32 and the lower reinforcing connecting portion 33 are connected between the upper end portions 31Z of the intermediate leg elements 31 and 31 and the lower portion 3b.

このように、中間脚要素３１、３１は天板２側への接続点となる付け根に近い位置で上補強連結部３２によって相互に連結される以外に、脚３の付け根から遠い位置において下補強連結部３３によっても相互に連結されるため、中間脚要素３１、３１の付け根に過大な倒れモーメント荷重が集中することを回避することができる。中間脚要素３１、３１を取り付けた場合、天板幅方向Ｘに沿った天板２の横揺れには中間脚要素３１、３１の倒れが伴うが、このように中間脚要素３１、３１の倒れを抑える結果、天板２の横揺れに対する強度を有効に高めることができる。そして、単に２つの中間脚要素３１、３１を追加して相互に上下の補強連結部３２、３３で連結するだけであるから、構造躯体である天板２や横架材１４、端部脚１１等を抜本的に重厚とすることなく、天板２の横揺れに簡易に対応することが可能となる。 As described above, the intermediate leg elements 31 and 31 are connected to each other by the upper reinforcing connecting portion 32 at a position close to the base serving as a connection point to the top plate 2 side, and the lower reinforcement is provided at a position far from the base of the leg 3. Since it is mutually connected also by the connection part 33, it can avoid that an excessive fall moment load concentrates on the root of the intermediate leg elements 31 and 31. FIG. When the intermediate leg elements 31 and 31 are attached, the roll of the top board 2 along the top board width direction X is accompanied by the fall of the intermediate leg elements 31 and 31. Thus, the fall of the intermediate leg elements 31 and 31 is caused. As a result, the strength against rolling of the top plate 2 can be effectively increased. And since the two intermediate leg elements 31 and 31 are simply added and connected to each other by the upper and lower reinforcing connecting portions 32 and 33, the top plate 2, the horizontal member 14, and the end legs 11 which are structural housings. Thus, it is possible to easily cope with the roll of the top plate 2 without drastically increasing the thickness.

また、下補強連結部３３は、一対の中間脚要素３１、３１の間を連結する面板部３ｐ、３ｑを供えており、面板部３ｐ、３ｑは、図２に一点鎖線で示すように一方の中間脚要素３１の上端部３１ａ側と他方の中間脚要素３１の下端部３１ｂ側との間をたすき掛け状に連結する連結機能を含んでいるため、一対の中間脚要素の倒れに対して高い強度を実現することができる。 Further, the lower reinforcing connecting portion 33 is provided with face plate portions 3p and 3q for connecting the pair of intermediate leg elements 31 and 31, and the face plate portions 3p and 3q are provided on one side as shown by a one-dot chain line in FIG. Since it includes a connecting function for connecting the upper end portion 31a side of the intermediate leg element 31 and the lower end portion 31b side of the other intermediate leg element 31 in a hanging manner, it is high against a fall of the pair of intermediate leg elements Strength can be realized.

勿論、このような面板部３ｐ、３ｑによって、一対の中間脚要素３１、３１の間がたすき掛け状となるだけでなく、面板部３ｐ、３ｑを介してまんべんなく連結されるので、一層の強度確保とともに、図７に示す中間脚要素３１、３１間の隙間（凹み部分）３１１を埋める化粧材としても機能し、外観の向上に資するものとなる。 Of course, such face plate portions 3p and 3q not only form a staking shape between the pair of intermediate leg elements 31 and 31, but are connected evenly through the face plate portions 3p and 3q. At the same time, it also functions as a cosmetic material that fills the gap (recessed portion) 311 between the intermediate leg elements 31 and 31 shown in FIG. 7, and contributes to the improvement of the appearance.

さらに、本実施形態のテーブルＴは、上記のように一対の端部脚１１の間を複数の横架材１４で連結して脚体１を構成し、この脚体１に天板２を支持させてなるものであり、隣接する横架材１４の間を脚受け部材４で接続し、中間脚要素３１、３１の間を連結する上補強連結部３２が前記脚受け部材４を含んで構成されている。すなわち、中間脚要素３１、３１の上端部間３１Ｚが脚受け部材４によって連結され、この脚受け部材４が横架材１４に接続されるので、中間脚要素３１、３１の倒れ剛性が脚受け部材４を介して有効に高められることになる。しかも、脚受け部材４は複数の横架材１４の間を連結するため、脚受け部材４に横架材１４の振動の腹の部分を抑えて制振作用を営ませることができる。 Furthermore, the table T of this embodiment comprises the leg 1 by connecting the pair of end legs 11 with the plurality of horizontal members 14 as described above, and supports the top plate 2 on the leg 1. An upper reinforcing connecting portion 32 that connects the adjacent horizontal members 14 with the leg support members 4 and connects between the intermediate leg elements 31, 31 includes the leg support members 4. Has been. That is, 31Z between the upper end portions of the intermediate leg elements 31 and 31 are connected by the leg support member 4, and this leg support member 4 is connected to the horizontal member 14, so that the falling rigidity of the intermediate leg elements 31 and 31 is the leg support. It is effectively increased through the member 4. In addition, since the leg receiving member 4 connects the plurality of horizontal members 14, the leg receiving member 4 can suppress a portion of the vibration of the horizontal member 14 so as to exert a damping action.

そして、この実施形態のテーブルＴは、天板幅方向Ｘと直交する奥行き方向Ｙに、対面で使用可能な一対の天板２が所定の隙間Ａを介して配置され、中間脚要素３１、３１はそれら天板２間の隙間Ａの下方に配置されているので、テーブルＴに対面で着座した場合に中間脚要素３１、３１がテーブルＴの内奥に位置し、下肢空間Ｚの利用の妨げなることを適切に防止して、フリーアドレスタイプのテーブルＴとしての機能を有効に担保することができる。 In the table T of this embodiment, a pair of top plates 2 that can be used facing each other are arranged in a depth direction Y orthogonal to the top plate width direction X with a predetermined gap A therebetween, and intermediate leg elements 31, 31. Is disposed below the gap A between the top plates 2, so that when sitting on the table T facing each other, the intermediate leg elements 31, 31 are located in the inner side of the table T, preventing the use of the lower limb space Z. Thus, the function as the free address type table T can be effectively secured.

なお、各部の具体的な構成は、上述した実施形態のみに限定されるものではない。 The specific configuration of each unit is not limited to the above-described embodiment.

例えば、図８に示すように、一対の端部脚１１、１１の間１１Ｘを横架材１４で連結して脚体１を構成し、この脚体１に天板２を支持させてなるものにおいて、中間脚要素３１、３１の上端部間３１Ｚを横架材１４で連結するなど、中間脚要素３１、３１の間３１Ｘを連結する上補強連結部３２が前記横架材１４を含んで構成されてもよい。 For example, as shown in FIG. 8, a leg 1 is formed by connecting a pair of end legs 11, 11 </ b> X with a horizontal member 14, and the top 1 is supported by the leg 1. The upper reinforcement connecting portion 32 that connects the intermediate leg elements 31 and 31X between the upper end portions 31Z of the intermediate leg elements 31 and 31 by the horizontal member 14 includes the horizontal member 14. May be.

このように、中間脚要素３１、３１の上端部間３１Ｚが横架材１４によって連結されると、逆に横架材１４は少なくとも２つの中間脚要素３１、３１に支持されて剛性が高められるため、特に横架材１４の固有振動数に起因して横揺れが増幅する場合には、横架材１４の剛性が高められることによって固有振動数が上がり、共振現象が抑えられる利点がある。 As described above, when the upper end portion 31Z of the intermediate leg elements 31 and 31 is connected by the horizontal member 14, the horizontal member 14 is supported by at least two intermediate leg elements 31 and 31 to increase the rigidity. Therefore, in particular, when the rolling is amplified due to the natural frequency of the horizontal member 14, the rigidity of the horizontal member 14 is increased, so that the natural frequency is increased and the resonance phenomenon can be suppressed.

また、同図に示すように、下補強連結部３３は、一方の中間脚要素３１の上端部３１ａ側と他方の中間脚要素３１の下端部３１ｂ側との間３１Ｘをたすき掛け状に連結する補強部材３５等であってもよく、このような補強部材３５を上記実施形態と同様の面板部３ｒと併用して用いることもできる。 Further, as shown in the figure, the lower reinforcing connecting portion 33 connects 31X between the upper end portion 31a side of one intermediate leg element 31 and the lower end portion 31b side of the other intermediate leg element 31 in a staking manner. The reinforcing member 35 or the like may be used, and such a reinforcing member 35 may be used in combination with the face plate portion 3r similar to the above embodiment.

さらに、横架材１４と端部脚１１との接続構造は、上記実施形態のようなジョイント材１５に限らず、例えば図９に示すように、単に横架材１４の端面１４ａに板状のブラケット１８を固定し、この板状のブラケット１８を端部脚１１を構成する横桟１３の立面１３ａに取り付けるようにしてもよい。このような場合にも、上記のような中間脚要素を設けることで天板に対する横揺れ防止効果が得られる点は上記と同様である。 Furthermore, the connection structure between the horizontal member 14 and the end leg 11 is not limited to the joint material 15 as in the above-described embodiment. For example, as illustrated in FIG. 9, a plate-like structure is simply formed on the end surface 14 a of the horizontal member 14. The bracket 18 may be fixed, and the plate-like bracket 18 may be attached to the upright surface 13a of the cross rail 13 constituting the end leg 11. Even in such a case, the provision of the intermediate leg element as described above provides the same effect as described above in that a roll prevention effect with respect to the top plate can be obtained.

また、本発明の適用対象は端部脚１１の間を横架材１４で連結するものに限らず、図１０に示すように、一対の端部脚１１、１１の間を天板２で直接連結して構成されるテーブルにおいては、中間脚要素３１、３１を天板２に直付けすることで、中間脚要素３１、３１の間を連結する上補強連結部３２を前記天板２を含んで構成してもよい。 Further, the application object of the present invention is not limited to the connection between the end legs 11 by the horizontal member 14, and the top plate 2 directly connects between the pair of end legs 11, 11 as shown in FIG. 10. In the table constituted by connecting, the upper leg connecting portion 32 including the upper plate 2 is connected to the intermediate plate elements 31, 31 by directly attaching the intermediate leg elements 31, 31 to the top plate 2. You may comprise.

このようにしても、天板２を介して中間脚要素３１、３１の倒れ剛性を有効に高めることができる。その上、中間脚要素３１、３１の上端部間が天板２によって連結されると、逆に天板２は少なくとも２つの中間脚要素３１、３１に支持されて剛性が高められることとなるため、天板２の固有振動数に起因して横揺れが増幅する場合には、天板２の剛性が高められることによって固有振動数が上がり、共振現象が抑えられる利点がある。 Even if it does in this way, the fall rigidity of the intermediate leg elements 31 and 31 can be effectively improved through the top plate 2. FIG. In addition, if the upper end portions of the intermediate leg elements 31, 31 are connected by the top plate 2, the top plate 2 is supported by at least two intermediate leg elements 31, 31 and the rigidity is increased. When the rolling is amplified due to the natural frequency of the top plate 2, the rigidity of the top plate 2 is increased, so that the natural frequency is increased and the resonance phenomenon is suppressed.

さらにまた、本発明の適用対象は天板２が奥行き方向Ｙに分割しているものに限らず、例えば図１１に示すように、奥行き方向Ｙに一枚の大型天板６で構成されて、対面で使用可能な一対の天板領域Ｓが設定されているテーブルにおいても、中間脚要素３１、３１をそれら天板領域Ｓ、Ｓ間の境界部付近を支持する位置に配置すれば、上記実施形態と同様の効果が奏される。 Furthermore, the application target of the present invention is not limited to the one in which the top plate 2 is divided in the depth direction Y. For example, as shown in FIG. Even in a table in which a pair of top plate areas S that can be used in a face-to-face manner is set, if the intermediate leg elements 31 and 31 are arranged at positions that support the vicinity of the boundary between the top plate areas S and S, the above-described implementation The same effect as the form is produced.

その他、中間脚要素を３つ以上使用したり、端部脚にパネルタイプのものを採用するなど、本発明の趣旨を逸脱しない範囲で種々変形が可能である。 In addition, various modifications can be made without departing from the gist of the present invention, such as using three or more intermediate leg elements or adopting a panel type for the end legs.
