Description

本発明は、前後方向を向くベース脚と、該ベース脚に取り付けられた支柱とによって構成される家具の脚体に関する。 The present invention relates to a leg body of furniture constituted by a base leg that faces in the front-rear direction and a post attached to the base leg.

従来、会議等に利用されるテーブルには、天板を支持する左右一対の脚が設けられている。脚は、天板を直接支持する天板支持部と、この天板支持部を支持する２つの筒状部材を有する縦脚部から成る脚本体部と、これを支持する着脱可能な足部とから構成されている（例えば、特許文献１参照）。 Conventionally, a table used for a meeting or the like is provided with a pair of left and right legs that support a top board. The leg includes a top plate support portion that directly supports the top plate, a leg main body portion that includes a vertical leg portion having two cylindrical members that support the top plate support portion, and a detachable foot portion that supports the leg body portion. (For example, refer to Patent Document 1).

足部は前後に、長い足要素と短い足要素を前後一対で有し、両足要素の対向する互いの端部にはそれぞれ凸部と孔が併設されている。そして、一方の足要素の凸部と孔が、他方の足要素の孔と凸部に互いに嵌合して位置決めされ、さらに、足要素の両端部が連結部材を用いて締結され足部を構成した後、各足要素をそれぞれ筒状部材に螺着することで脚を構成している。 The foot part has a pair of front and rear long foot elements and a pair of front and back foot parts, and a projecting part and a hole are provided at the opposite ends of both foot elements. And the convex part and the hole of one foot element are mutually fitted and positioned in the hole and the convex part of the other foot element, and further, both ends of the foot element are fastened using connecting members to constitute the foot part. After that, each leg element is screwed to the cylindrical member to constitute a leg.

特開２００２−１７７０５４号公報（段落００１０〜１６、図１，図４，図５）Japanese Patent Laid-Open No. 2002-177054 (paragraphs 0010 to 16, FIGS. 1, 4 and 5)

しかしながら、特許文献１にあっては、天板に上方から大きな荷重が加えられた場合に、両足要素の接続部に大きな負荷が加わって両足要素間に撓みが生じ、脚上部の天板に掛かる荷重を安定して支持することが困難であり、これを避けるため足要素の上下寸法を大きめに設定すれば撓みを防げるが、脚全体が重厚になり、美観を損なう虞があった。 However, in Patent Document 1, when a large load is applied to the top plate from above, a large load is applied to the connecting portion of the both foot elements to cause bending between the both foot elements, and the top plate on the upper leg portion is applied. In order to avoid this, it is difficult to stably support the load, and if the vertical dimension of the foot element is set to be large, bending can be prevented, but the entire leg becomes heavy and there is a possibility that the aesthetic appearance is impaired.

本発明は、このような問題点に着目してなされたもので、脚全体の上下寸法を大きくすることなく、上方からの大きな荷重に対して撓みを極力抑え、脚上部からの荷重を安定して支持することができる家具の脚体を提供することを目的とする。 The present invention has been made paying attention to such problems, and without increasing the vertical dimension of the entire leg, the deflection from a large load from above is suppressed as much as possible to stabilize the load from the upper part of the leg. It is an object of the present invention to provide a furniture leg that can be supported.

上記課題を解決するために、本発明の請求項１に記載の家具の脚体は、前後方向を向くベース脚と、該ベース脚に取り付けられた支柱とによって構成される家具の脚体であって、前記ベース脚には、前後方向の略全範囲にわたり、両先端の足先部から支柱が取り付けられている部分に向ってベース脚下面より下方への突出する突出寸法が漸次大となるリブが垂設され、前記ベース脚は、前記支柱にそれぞれ取り付けられ、端部同士が当接連結される一対の脚部材で構成され、両脚部材が連結した際に、前記脚部材の各リブが互いに当接しあうことを特徴としている。
この特徴によれば、ベース脚の前後方向の略全範囲にわたり両先端足先部から支柱が取り付けられている部分に向って下方への突出寸法が漸次大となるリブが垂設されているので、上方からの大きな荷重が支柱を介してベース脚に加えられた場合であっても、支柱直下の最も荷重の掛かる部分を突出寸法の大きいリブで安定確実に支持させることが可能であり脚全体の上下寸法を大きくする必要がなく、しかもリブが前後方向に延在しているのでベース脚の撓みも極力抑えられ、ベース脚上部の家具の荷重を安定して支持できる。またベース脚を一対の脚部材で構成したので、支柱上部の家具の大きさや重量に応じて、脚部材の長さを任意に選択することができる。また、両脚部材が連結した際に両脚部材の各リブが互いに当接しあうので、支柱を介して大きな荷重が両脚部材に作用した際、リブ同士が衝合して両脚部材の撓みを低減させることができる。 In order to solve the above-mentioned problem, a furniture leg according to claim 1 of the present invention is a furniture leg constituted by a base leg facing in the front-rear direction and a column attached to the base leg. In the base leg, a rib whose projecting dimension gradually protrudes downward from the lower surface of the base leg toward the part where the support is attached from the tip part of both ends over substantially the entire range in the front-rear direction. The base legs are each composed of a pair of leg members that are respectively attached to the support columns and whose ends are in contact with each other, and when the both leg members are connected, the ribs of the leg members are mutually connected. It is characterized by contacting each other .
According to this feature, since the ribs that gradually protrude downward from the tip ends of both ends toward the portion where the support column is attached are suspended over substantially the entire range of the base leg in the front-rear direction. Even when a large load from above is applied to the base leg through the support column, it is possible to stably and reliably support the most loaded part directly below the support column with a rib with a large protruding dimension. Since the ribs extend in the front-rear direction, it is possible to suppress the bending of the base leg as much as possible and to stably support the load of furniture on the upper part of the base leg. Further, since the base leg is composed of a pair of leg members, the length of the leg member can be arbitrarily selected according to the size and weight of the furniture above the support column. Also, since the ribs of both leg members come into contact with each other when both leg members are connected, when a large load acts on both leg members through the support pillars, the ribs collide with each other to reduce the deflection of both leg members. Can do.

本発明の請求項２に記載の家具の脚体は、請求項１に記載の家具の脚体であって、前記リブを、前記ベース脚の左右幅方向の略中央位置から下向きに垂設したことを特徴としている。
この特徴によれば、リブが、ベース脚の幅方向における略中央位置から下向きに垂設さているので、ベース脚を床面に設置した際に、リブの外側からの視認性を低くできる。 A furniture leg according to a second aspect of the present invention is the furniture leg according to the first aspect, wherein the rib is hanged downward from a substantially central position in a lateral width direction of the base leg. It is characterized by that.
According to this feature, since the rib is laid downward from the substantially center position in the width direction of the base leg, visibility from the outside of the rib can be reduced when the base leg is installed on the floor surface.

本発明の請求項３に記載の家具の脚体は、請求項１または２に記載の家具の脚体であって、前記ベース脚を、左右幅方向における両側端緑から側壁が垂下する逆凹字状とし、該両側壁内面から、左右幅方向の中央に向かって挟持片を延設して前記リブに固着したことを特徴としている。
この特徴によれば、ベース脚を逆凹字状とすることで軽量化を図ると共に、ベース脚の左右の両側壁から延設された挟持片をリブに固着したことで、リブがベース脚内で強度的に補強された状態で保持され、支柱からの大きな荷重が加わった場合にも、挟持片に力を分散させることができる。 A furniture leg according to a third aspect of the present invention is the furniture leg according to the first or second aspect, wherein the base leg is a reverse concave in which the side wall hangs down from the green at both ends in the left-right width direction. A sandwiching piece is extended from the inner surfaces of both side walls toward the center in the left-right width direction and fixed to the rib.
According to this feature, the base leg has an inverted concave shape to reduce the weight, and the clamping pieces extending from the left and right side walls of the base leg are fixed to the rib, so that the rib is within the base leg. Even when a large load is applied from the support column, the force can be distributed to the sandwiching pieces.

本発明の請求項４に記載の家具の脚体は、請求項３に記載の家具の脚体であって、前記挟持片を前後方向に複数設けたことを特徴としている。
この特徴によれば、ベース脚の軽量化と支持強化をより一層向上させることができる。 A furniture leg according to a fourth aspect of the present invention is the furniture leg according to the third aspect, wherein a plurality of the clamping pieces are provided in the front-rear direction.
According to this feature, it is possible to further improve the weight reduction and the support reinforcement of the base leg.

本発明の請求項５に記載の家具の脚体は、請求項１乃至４のいずれかに記載の家具の脚体であって、前記支柱は、前記ベース脚に設けた下向き開口部から挿入したボルトで螺着されるものとし、該ボルトの頭部を、前記開口部内に収納したことを特徴としている。
この特徴によれば、ボルトでベース脚を支柱に締結した際に、ボルトの頭部が開口部内に収納されるので、脚部材を床面に接地した際にボルトの頭部が床面側に向けて突出されることが防止されるので、床面に傷を生じさせることがない。 The furniture leg according to claim 5 of the present invention is the furniture leg according to any one of claims 1 to 4, wherein the column is inserted through a downward opening provided in the base leg. It is assumed that the bolt is screwed and the head of the bolt is housed in the opening.
According to this feature, when the base leg is fastened to the column with the bolt, the head of the bolt is housed in the opening, so that when the leg member is grounded to the floor, the head of the bolt is brought to the floor surface side. Since it is prevented from protruding toward the floor, the floor surface is not damaged.

Tapered surfaces 26a and 26a 'are formed in parallel with each other.

そこで、第１脚部材２１の嵌合片２４を第２脚部材２１’の嵌合溝２５’に向けて、第２脚部材２１’の嵌合片２４’を第１脚部材２１の嵌合溝２５に向けて嵌合していくと、一方の嵌合片２４のテーパ面２４ａが嵌合溝２５’のテーパ面２５ａ’に当接され、他方の嵌合片２４’のテーパ面２４ａ’が嵌合溝２５のテーパ面２５ａに沿って当接され、嵌合片２４，２４’のボルト用貫通孔２４ｂ，２４ｂ’と嵌合溝２５’，２５とが連通状態となるようにする。そして、接続端面２３ａと接続端面２３ａ’およびリブ端面３１とリブ端面３１’とが互いに当接される。 Therefore, the fitting piece 24 of the first leg member 21 faces the fitting groove 25 ′ of the second leg member 21 ′, and the fitting piece 24 ′ of the second leg member 21 ′ is fitted to the first leg member 21. When fitting toward the groove 25, the taper surface 24a of one fitting piece 24 comes into contact with the taper surface 25a 'of the fitting groove 25', and the taper surface 24a 'of the other fitting piece 24'. Are brought into contact with each other along the taper surface 25a of the fitting groove 25 so that the bolt through holes 24b and 24b 'of the fitting pieces 24 and 24' and the fitting grooves 25 'and 25 are in communication with each other. The connection end surface 23a and the connection end surface 23a ', and the rib end surface 31 and the rib end surface 31' are brought into contact with each other.

図５に示されるように、リブ端面３１とリブ端面３１’が前後に整合して当接されるとともに、接続端面２３ａと接続端面２３ａ’が相互に当接されると同時に、嵌合溝２５’に嵌合片２４が嵌合され、嵌合溝２５に嵌合片２４’が嵌合されることで、嵌合片２４と嵌合片２４’とが側面視で嵌合溝２５’と嵌合溝２５に相互にクロスした状態で嵌合されるので、第１脚部材２１および第２脚部材２１’が上下左右方向に移動不能に規制され仮固定される。 As shown in FIG. 5, the rib end surface 31 and the rib end surface 31 ′ are in contact with each other in the front-rear direction, and the connection end surface 23 a and the connection end surface 23 a ′ are in contact with each other, and at the same time, the fitting groove 25. When the fitting piece 24 is fitted into the fitting groove 24 and the fitting piece 24 ′ is fitted into the fitting groove 25, the fitting piece 24 and the fitting piece 24 ′ are seen from the fitting groove 25 ′ in a side view. Since the first and second leg members 21 and 21 ′ are fitted to the fitting groove 25 in a state of crossing each other, the first leg member 21 and the second leg member 21 ′ are restricted from being movable in the vertical and horizontal directions and temporarily fixed.

次いで、図５および図６（ａ）に示されるように、嵌合片２４の背面側の近傍に形成された開口部２６からボルト用貫通孔２４ｂに向けて、締結手段に相当するボルト５１が挿通され、さらに、ボルト孔２５ｂ’に向けて螺合されていく。尚、ボルト５１の取り付け作業を容易かつ確実に行うため本実施例では六角レンチ５９を用いて作業が行われる。このように、開口部２６を形成したことで、嵌合片２４から嵌合溝２５’に向けてボルト５１を締結する際に、この開口部２６を利用してボルト５１の回動操作が行い易い構成になっている。 Next, as shown in FIG. 5 and FIG. 6A, a bolt 51 corresponding to a fastening means is provided from the opening 26 formed in the vicinity of the back surface side of the fitting piece 24 toward the bolt through hole 24b. It is inserted and further screwed toward the bolt hole 25b ′. In this embodiment, a hexagon wrench 59 is used to easily and reliably attach the bolt 51. Thus, by forming the opening 26, when the bolt 51 is fastened from the fitting piece 24 to the fitting groove 25 ′, the opening of the bolt 51 is performed using the opening 26. It is easy to configure.

そして、ボルト５１が六角レンチ５９の回動操作により、ボルト用貫通孔２４ｂを介してボルト孔２５ｂ’に向けて螺合し締め込まれていくことで、嵌合片２４が嵌合溝２５’内に引き込まれ締結されるとともに、図５および図６（ｂ）に示されるように、ボルト５１が開口部２６’からボルト用貫通孔２４ｂ’を介してボルト孔２５ｂに向けて螺合し締め込まれていくことで、嵌合片２４’が嵌合溝２５内に引き込まれて締結される。嵌合溝２５’に嵌合片２４が嵌合され、嵌合溝２５に嵌合片２４’が嵌合されることで、一方の当接面（テーパ面２４ａとテーパ面２５ａ’）が他方の当接面（テーパ面２４ａ’とテーパ面２５ａ）とが側面視で相互にクロスした方向に引き込まれるので、嵌合片２４，２４’と嵌合溝２５’，２５との圧着が非常に強固なものとなる。 The bolt 51 is screwed and tightened to the bolt hole 25b ′ through the bolt through hole 24b by the turning operation of the hexagon wrench 59, whereby the fitting piece 24 is fitted into the fitting groove 25 ′. As shown in FIGS. 5 and 6 (b), the bolt 51 is screwed and tightened from the opening 26 'to the bolt hole 25b through the bolt through hole 24b'. By being inserted, the fitting piece 24 ′ is drawn into the fitting groove 25 and fastened. By fitting the fitting piece 24 into the fitting groove 25 ′ and fitting the fitting piece 24 ′ into the fitting groove 25, one abutment surface (tapered surface 24 a and tapered surface 25 a ′) becomes the other. Since the contact surfaces (tapered surface 24a 'and tapered surface 25a) are pulled in a direction crossing each other in a side view, the crimping between the fitting pieces 24, 24' and the fitting grooves 25 ', 25 is extremely high. It will be solid.

同様にして、この一対のボルト５１，５１の締め込みにより、対向する前後のリブ端面３１とリブ端面３１’および、同じく対向する接続端面２３ａと接続端面２３ａ’の圧着も強固となる。このようにして、第１脚部材２１と第２脚部材２１’が左右の２箇所で連結されて、前後方向を向く堅固なベース脚５が構成される。尚、ベース脚５の前後端部を構成する足先部２１ａ，２１ａ’の設けられたアジャスタ３３，３３によって、左右の側壁２１ｃ，２１ｃ’および、その中央位置のリブ３０，３０’の下面が床面６０から若干離間されている。 Similarly, by tightening the pair of bolts 51, 51, the front and rear rib end surfaces 31 and the rib end surfaces 31 'and the connecting end surface 23a and the connecting end surface 23a' facing each other are firmly pressed. In this way, the first leg member 21 and the second leg member 21 ′ are connected at the two left and right positions to form a rigid base leg 5 that faces in the front-rear direction. The left and right side walls 21c and 21c ′ and the lower surfaces of the ribs 30 and 30 ′ at the center position thereof are adjusted by the adjusters 33 and 33 provided with the foot portions 21a and 21a ′ constituting the front and rear ends of the base leg 5. It is slightly spaced from the floor surface 60.

図６（ａ）（ｂ）に示されるように、側面視でクロスしたボルト５１，５１のボルト頭部５１ａ，５１ａの受ける面であるテーパ面２６ａ，２６ａ’は、嵌合片２４，２４’および嵌合溝２５’２５のそれぞれに対面するテーパ面２４ａ，２５ａ’とテーパ面２４ａ’，２５ａ’に平行な面で形成されているため、ボルト５１，５１の螺合時に、各ボルト頭部５１ａ，５１ａを受けるテーパ面２６ａ，２６ａ’に無理な負荷を加えることなく、各ボルト５１，５１の回動操作をより円滑に行えると共に、嵌合片と嵌合溝とに強い圧着作用を与えることができる。 As shown in FIGS. 6 (a) and 6 (b), the tapered surfaces 26a and 26a ′, which are the surfaces received by the bolt heads 51a and 51a of the bolts 51 and 51 crossed in a side view, are the fitting pieces 24 and 24 ′. Since the taper surfaces 24a and 25a 'facing each of the fitting grooves 25'25 and the surfaces parallel to the taper surfaces 24a' and 25a 'are formed, when the bolts 51 and 51 are screwed, each bolt head The bolts 51 and 51 can be rotated more smoothly without applying an excessive load on the tapered surfaces 26a and 26a 'that receive the 51a and 51a, and a strong crimping action is applied to the fitting piece and the fitting groove. be able to.

しかも、各ボルト５１，５１の締結後にボルト頭部５１ａ，５１ａは、それぞれの開口部２６，２６’内に収納されるので、両脚部材２１，２１’を床面６０に接地した際にボルト頭部５１ａ，５１ａが床面６０側に向けて突出されることはなく、床面６０に対して傷を生じさせることが未然に防止されている。 In addition, since the bolt heads 51a and 51a are accommodated in the respective openings 26 and 26 'after the bolts 51 and 51 are fastened, the bolt heads when the both leg members 21 and 21' are grounded to the floor surface 60. The portions 51a and 51a are not protruded toward the floor surface 60, and the floor surface 60 is prevented from being damaged.

そして、第１脚部材２１と第２脚部材２１’の開口部２６，２７’，２７，２６’に形成されたボルト用貫通孔２８ａ，２８ｂ’，２８ｂ，２８ａ’に下方から上方に向けて４本のボルト５３を上方に向けて挿通させ、両脚部材２１，２１’の上部の支持面２８，２８’に支柱３の下端３ｃを当接載置して、この支柱３の下端部に上下方向に向けて形成されたボルト穴３ａ，３ｂ，３ａ，３ｂをボルト用貫通孔２８ａ，２８ｂ’，２８ｂ，２８ａ’と重なるように位置合わせをした後、六角レンチ５９の回動操作により、各ボルト５３をボルト穴３ａ，３ｂ，３ａ，３ｂに螺合することで、支柱３が両脚部材２１，２１’の各左右２箇所で直に締結され、支柱と両脚部材との連結強度を高めることができる。 The bolt through holes 28a, 28b ', 28b, 28a' formed in the openings 26, 27 ', 27, 26' of the first leg member 21 and the second leg member 21 'are directed from below to above. The four bolts 53 are inserted upward, and the lower end 3c of the support column 3 is placed in contact with the upper support surfaces 28 and 28 'of the both leg members 21 and 21'. The bolt holes 3a, 3b, 3a, 3b formed in the direction are aligned so as to overlap the bolt through holes 28a, 28b ′, 28b, 28a ′. By screwing the bolt 53 into the bolt holes 3a, 3b, 3a, 3b, the support column 3 is directly fastened at the left and right positions of the both leg members 21, 21 ′, thereby increasing the connection strength between the support column and the both leg members. Can do.

しかも、各ボルト５３で両脚部材２１，２１’を支柱３に締結する際に、脚部材２１，２１’の下向きに開口された開口部２６，２７’，２７，２６’から支柱３に向けて、各ボルト５３をねじ込んで、これらボルト５３の締結後にボルト頭部５３ａを各開口部２６，２７’，２７，２６’内に収納することで、両脚部材２１，２１’を床面６０に接地した際にボルト頭部５３ａが床面６０側に向けて突出されることはなく、床面６０に傷を生じさせることが未然に防止される。このように、各々が下方から打ち込まれるボルト５３によって、支柱３に対して直に締結されるので、例えばＬ字の取付金具等を別途用いることなく、支柱３と両脚部材２１，２１’の連結強度を高めることができ、天板２上方からの大きな荷重が加わった場合であっても、支柱３を介して天板２を安定して支持可能な撓みにくいベース脚５の構造となる。 In addition, when the both leg members 21 and 21 ′ are fastened to the column 3 by the bolts 53, the openings 26, 27 ′, 27, and 26 ′ opened downward from the leg members 21, 21 ′ are directed toward the column 3. The bolts 53 are screwed and the bolt heads 53a are housed in the openings 26, 27 ', 27, 26' after the bolts 53 are fastened, so that both the leg members 21, 21 'are grounded to the floor surface 60. In this case, the bolt head 53a is not protruded toward the floor surface 60, and it is possible to prevent the floor surface 60 from being damaged. Thus, since each is directly fastened with respect to the support | pillar 3 with the volt | bolt 53 driven from the downward | lower direction, for example, without using an L-shaped attachment bracket etc. separately, the connection of the support | pillar 3 and both leg members 21 and 21 ' Even when a large load is applied from above the top plate 2, the strength of the base leg 5 can be increased and the base plate 5 can be stably supported via the support column 3.

以上の説明により実施例では、ベース脚５を前後一対の両脚部材２１，２１’で構成し、両脚部材２１，２１’が連結した際に、リブ端面３１，３１’を同士が互いに当接した状態で連結し、ベース脚５を一つの支柱３に固着したことで、支柱３を介して大きな荷重が両脚部材２１，２１’に作用した際に、リブ３０，３０’同士が互いに衝合しあうので、両脚部材２１，２１’の撓みが低減される。また、一対の両脚部材２１，２１’でベース脚５が構成されたことで、例えば、天板２の大きさや形状、テーブル１に載置される物品の荷重に合わせて、両脚部材２１，２１’の前後方向の長さを任意に変更、交換できるとともに、その施工が容易に行える。また、両脚部材２１，２１’の両接続部２３，２３’の構造が対称形であるので、位置決めがし易く、部品の共用化によるコストの低減も図れる。 According to the above description, in the embodiment, the base leg 5 is composed of a pair of front and rear leg members 21 and 21 ′, and when the leg members 21 and 21 ′ are connected, the rib end surfaces 31 and 31 ′ abut each other. Since the base legs 5 are fixed to one support column 3 when a large load is applied to both leg members 21 and 21 'through the support columns 3, the ribs 30 and 30' collide with each other. As a result, the bending of both leg members 21, 21 'is reduced. In addition, since the base leg 5 is configured by the pair of both leg members 21, 21 ′, for example, the both leg members 21, 21 according to the size and shape of the top plate 2 and the load of the article placed on the table 1. The length in the front-rear direction can be changed and replaced arbitrarily, and its construction can be performed easily. Further, since the structures of the connecting portions 23 and 23 'of the both leg members 21 and 21' are symmetrical, positioning is easy, and cost can be reduced by sharing parts.

このように、ベース脚５の前後方向の略全範囲にわたり両前後先端の足先部２１ａ，２１ａ’から支柱３が固着される接続部２３，２３’に向って下方への突出寸法が漸次大となるリブ３０，３０’が垂設されているので、上方からの大きな荷重が支柱３を介して、ベース脚５に加えられた場合であっても、支柱３直下の最も荷重の掛かる部分を突出寸法の大きいリブ３０，３０’で安定確実に支持することが可能となるので、両脚部材２１，２１’全体の上下寸法を大きくする必要がなく、しかもリブ３０，３０’が前後方向に延在しているので、ベース脚５の撓みも極力抑えられ、天板２の上部から加わる荷重に対しても強い支持強度を備えた脚体４となる。 In this way, the projecting dimension downwards gradually increases from the front end portions 21a, 21a ′ of the front and rear ends toward the connection portions 23, 23 ′ to which the support column 3 is fixed over substantially the entire range of the base leg 5 in the front / rear direction. Since the ribs 30 and 30 ′ are vertically suspended, even if a large load from above is applied to the base leg 5 through the support column 3, the most loaded portion directly below the support column 3 Since the ribs 30 and 30 ′ having large projecting dimensions can be stably and reliably supported, it is not necessary to increase the overall vertical dimension of both leg members 21 and 21 ′, and the ribs 30 and 30 ′ extend in the front-rear direction. Therefore, the bending of the base leg 5 is suppressed as much as possible, and the leg body 4 having a strong support strength against a load applied from the upper part of the top plate 2 is obtained.

さらに、両脚部材２１，２１’を左右に側壁２１ｃ，２１ｃ’を備えた逆凹字状とすることで軽量化を図ると共に、この左右の両側壁２１ｃ，２１ｃ’から、挟持片２９，２９をリブ３０，３０’に固着したことで、リブ３０，３０’が各脚部材２１，２１’で強度的に補強された状態で保持されるので、支柱３からの大きな荷重が加わった場合にも、挟持片２９，２９に力を分散させることができる。また、リブ３０，３０’が、ベース脚５の幅方向における略中央位置から下向きに垂設さているので、ベース脚５を床面６０に設置した際に、リブ３０，３０’の外側からの視認性を低くでき、外部からの見栄えも損なうことがない。 Further, the leg members 21 and 21 'are formed in a reverse concave shape having side walls 21c and 21c' on the left and right sides, so that the weight is reduced, and the sandwiching pieces 29 and 29 are formed from the left and right side walls 21c and 21c '. Since the ribs 30 and 30 ′ are held in a state where they are reinforced in strength by the leg members 21 and 21 ′ by being fixed to the ribs 30 and 30 ′, even when a large load is applied from the column 3 The force can be distributed to the sandwiching pieces 29 and 29. Further, since the ribs 30 and 30 ′ are suspended downward from a substantially central position in the width direction of the base leg 5, when the base leg 5 is installed on the floor surface 60, the ribs 30 and 30 ′ Visibility can be lowered and appearance from the outside is not impaired.

以上、本発明の実施例を図面により説明してきたが、具体的な構成はこれら実施例に限られるものではなく、本発明の要旨を逸脱しない範囲における変更や追加があっても本発明に含まれ、例えば上記実施例では、脚体４が天板２を支持するテーブルとして説明したが、テーブルに限らず机や、その他脚体４に支持されるキャビネット等の家具にも適用できる。 Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. For example, in the above-described embodiment, the leg 4 is described as a table that supports the top plate 2, but the present invention is not limited to the table and can be applied to a desk or other furniture such as a cabinet supported by the leg 4.

また、上記実施例では、側壁２１ｃ，２１ｃ’からリブ３０，３０’に向けて、挟持片２９，２９’が延設されたことで、リブ３０，３０’が両脚部材２１，２１’内で強度的に補強される事から好ましいが、本発明はこれに限定されるものではなく、リブ３０，３０’を左右幅方向に幅広に成型することで、挟持片２９，２９’を用いずに強度を高めても良い。 Further, in the above embodiment, the sandwiching pieces 29 and 29 ′ are extended from the side walls 21c and 21c ′ toward the ribs 30 and 30 ′, so that the ribs 30 and 30 ′ are within the both leg members 21 and 21 ′. Although it is preferable because it is reinforced in strength, the present invention is not limited to this, and by forming the ribs 30 and 30 'wide in the left-right width direction, without using the sandwiching pieces 29 and 29'. The strength may be increased.

また、上記実施例では、リブ３０，３０’をベース脚５の左右幅方向の中央位置から前後の両足先部２１ａ，２１ａ’まで延設することで、撓みを極力抑えているが、本発明はこれに限定されるものではなく、例えば、リブ３０，３０’の長さを互いが当接される位置から両足先部２１ａ，２１ａ’まで延設することなく短かな寸法であっても良い。 Further, in the above embodiment, the ribs 30, 30 ′ are extended from the center position in the left-right width direction of the base leg 5 to the front and rear foot tips 21a, 21a ′, so that bending is suppressed as much as possible. Is not limited to this, and for example, the length of the ribs 30 and 30 ′ may be short without extending from the position where the ribs 30 and 30 ′ are in contact with each other to the both toe portions 21a and 21a ′. .

また、上記実施例では、ベース脚５を一対の脚部材２１，２１’接続して構成しているが、一本の脚部材で構成しても良い。この場合、リブは、支柱が取り付けられる近傍が一番突出しており両端足先部に向かって突出寸法が小さくなっていることは実施例の構成と同じである。 Moreover, in the said Example, although the base leg 5 was comprised by a pair of leg members 21 and 21 'connection, you may comprise by one leg member. In this case, the rib is the most prominent in the vicinity where the column is attached, and the projecting dimension is smaller toward the both-ends tip portion, as in the configuration of the embodiment.
