本発明は、テーブルの天板などの対象物を支持する支持脚に関する。 The present invention relates to a support leg that supports an object such as a table top.
例えば、テーブルの天板を支持する支持脚には、ダイカストなどの鋳造法により形成されたものがある（例えば、特許文献１参照）。ダイカストは、金属管などを加工して支持脚を製造する場合に比べ、デザインの自由度が高く、肉厚を部分的に変えることもできるなどの利点を有する。 For example, there is a support leg that supports the top plate of the table formed by a casting method such as die casting (see, for example, Patent Document 1). Die casting has advantages such as a higher degree of design freedom and a partial change in wall thickness compared to the case of manufacturing a support leg by processing a metal tube or the like.
しかし、支持脚全体をダイカストなどの鋳造法により製造すると、金型が大きくなり、コスト高となる。更に、金属管などの加工により製造された支持脚に比べて重量が大きくなる傾向がある。一方、支持脚全体を金属管とすると、軽量化、コストの低減を図ることができるものの、金属管の形状により、強度やデザインの上の制約を受ける場合がある。 However, if the entire support leg is manufactured by a casting method such as die casting, the mold becomes large and the cost increases. Furthermore, the weight tends to be larger than that of a support leg manufactured by processing a metal tube or the like. On the other hand, if the entire support leg is made of a metal tube, weight reduction and cost reduction can be achieved, but the shape of the metal tube may restrict the strength and design.
本発明は、上記問題点を解決するためになされたものであり、その目的は、強度やデザインの自由度を維持しつつ軽量化及びコストの低減を図ることのできる支持脚を提供することにある。 The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a support leg capable of reducing the weight and reducing the cost while maintaining the strength and the freedom of design. is there.

According to the above configuration, since a part of the support leg is composed of a support column having a through hole or a groove, for example, the weight of the support leg can be reduced and the cost can be reduced as compared with a case where the entire support leg is a cast product. Can do. Further, since the support is provided only on a part of the support leg, the strength and the degree of freedom of design can be maintained in the part other than the support.
上記支持脚について、前記支柱は、前記脚取付部を介して前記貫通孔又は前記溝部に挿通された締結部材により前記下側脚部に固定されることが好ましい。上記構成によれば、支柱は、下側脚部に設けられた連結部への接続に加え、脚取付部を介して挿通された締結部材により下側脚部に固定される。このため、支柱を、下側脚部と脚取付部とに強固に固定することができる。 About the said support leg, it is preferable that the said support | pillar is fixed to the said lower leg part by the fastening member inserted by the said through-hole or the said groove part via the said leg attachment part. According to the said structure, in addition to the connection to the connection part provided in the lower leg part, the support | pillar is fixed to a lower leg part by the fastening member inserted through the leg attaching part. For this reason, a support | pillar can be firmly fixed to a lower leg part and a leg attachment part.
上記支持脚について、前記上側脚部は、複数の前記支柱の端部が取り付けられる支柱取付部を上端部に備え、前記脚取付部は、前記支柱取付部を異なる角度で取付可能な取付孔を有することが好ましい。上記構成によれば、上側脚部を固定する支柱取付部は、脚取付部に対して異なる角度で取り付けられるので、支持脚を備える家具などの用途に応じて、支持脚を所望の向きで取り付けることができる。 With respect to the support leg, the upper leg portion includes a column mounting portion to which end portions of the plurality of columns are mounted at an upper end portion, and the leg mounting portion has mounting holes that can mount the column mounting portion at different angles. It is preferable to have. According to the above configuration, since the column attachment portion that fixes the upper leg portion is attached to the leg attachment portion at a different angle, the support leg is attached in a desired direction according to the application such as furniture provided with the support leg. be able to.

以下、図１〜図７を参照して、支持脚をテーブルに適用した一実施形態について説明する。
図１に示すように、テーブル１０は、長方形状の天板１１と、天板１１の下面に取り付けられた４つの支持脚１５とを備えている。支持脚１５は、脚部２０を備え、脚部２０は、下側脚部２１と、下側脚部２１の鉛直方向上方に連結された上側脚部２２とを有している。上側脚部２２は、鉛直方向に沿って延在し、下側脚部２１は、上端部から下端部にかけてテーブル１０の外側に向かって斜めに延びている。なお、「鉛直方向」とは、天板１１の上面及び下面に対して直交する方向であり、「水平方向」は、天板１１の上面及び下面と平行な方向である。
Hereinafter, an embodiment in which support legs are applied to a table will be described with reference to FIGS.
As shown in FIG. 1, the table 10 includes a rectangular top plate 11 and four support legs 15 attached to the lower surface of the top plate 11. The support leg 15 includes a leg portion 20, and the leg portion 20 includes a lower leg portion 21 and an upper leg portion 22 that is coupled to the lower leg portion 21 in the vertical direction. The upper leg portion 22 extends along the vertical direction, and the lower leg portion 21 extends obliquely toward the outside of the table 10 from the upper end portion to the lower end portion. The “vertical direction” is a direction orthogonal to the upper surface and the lower surface of the top plate 11, and the “horizontal direction” is a direction parallel to the upper surface and the lower surface of the top plate 11.
図２に示すように、天板１１の下面には、天板１１の長手方向に沿って延びる１対の突条１２が設けられている。それらの突条１２の間であって、突条１２の一方の端部側と他方の端部側には、細長状のブラケット１３がそれぞれ設けられている。ブラケット１３は、脚取付部１４を２つ備えている。脚取付部１４は、支持脚１５の一部を構成する。一つの脚取付部１４には、１本の脚部２０が取り付けられる。脚部２０は、天板１１の角部１６から中心に向かってオフセットされた位置に固定されている。 As shown in FIG. 2, a pair of ridges 12 extending along the longitudinal direction of the top plate 11 are provided on the lower surface of the top plate 11. Elongated brackets 13 are respectively provided between the ridges 12 on one end side and the other end side of the ridges 12. The bracket 13 includes two leg attachment portions 14. The leg attachment portion 14 constitutes a part of the support leg 15. One leg portion 20 is attached to one leg attachment portion 14. The leg portion 20 is fixed at a position offset from the corner portion 16 of the top plate 11 toward the center.
脚部２０は、脚取付部１４に対する取付角度を変更することにより、下側脚部２１の向きを変更することができる。例えば図２では、一つのブラケット１３に設けられた１対の脚部２０は、それらの下側脚部２１の延在方向がなす角度θ１が、例えば１２０度など、１８０度以下の所定角度となるように取り付けられている。 The leg portion 20 can change the orientation of the lower leg portion 21 by changing the attachment angle with respect to the leg attachment portion 14. For example, in FIG. 2, the pair of legs 20 provided on one bracket 13 has a predetermined angle of 180 degrees or less, such as 120 degrees, where the angle θ1 formed by the extending direction of the lower legs 21 is 120 degrees. It is attached to become.
また、図３に示すように、１つのブラケット１３に設けられる１対の脚部２０は、それらの下側脚部２１の延在方向が同一面内となるように取り付けることも可能である。このとき、１対の脚部２０の下側脚部２１は、ブラケット１３の長手方向と平行に延びる。１対の脚部２０を、下側脚部２１の延在方向が１８０度未満の角度をなすように設ける場合（図２参照）は、１対の脚部２０の下側脚部２１が平行である場合（図３参照）に比べ、天板１１の長辺側のスペースが拡大される。このため、長辺側にのみユーザが着座する場合に適している。また、１対の脚部２０の下側脚部２１を平行とすると、天板１１の短辺側にもユーザが着座しやすくなる。 Moreover, as shown in FIG. 3, it is also possible to attach the pair of legs 20 provided on one bracket 13 so that the extending directions of the lower legs 21 are in the same plane. At this time, the lower leg portion 21 of the pair of leg portions 20 extends in parallel with the longitudinal direction of the bracket 13. When the pair of legs 20 is provided so that the extending direction of the lower legs 21 forms an angle of less than 180 degrees (see FIG. 2), the lower legs 21 of the pair of legs 20 are parallel to each other. Compared to the case (see FIG. 3), the space on the long side of the top plate 11 is enlarged. For this reason, it is suitable when the user is seated only on the long side. Further, when the lower legs 21 of the pair of legs 20 are parallel, the user can easily sit on the short side of the top plate 11.
次に、図４〜図６を参照して、支持脚１５について詳述する。
図４に示すように、下側脚部２１の下端部には、アジャスタ２４が設けられている。下側脚部２１は、アルミニウムなどの金属単体、又はアルミニウム合金、亜鉛合金、銅合金、マグネシウム合金などの合金からなり、金型に溶融した金属を圧入するダイカストにより製造されている。下側脚部２１は、その上端部と下端部との間で湾曲し、湾曲した部分から下端部にかけて斜めに延びている。また、下側脚部２１は、延在方向に対して直交する方向の長さである幅Ｈが、下端部に向かうにつれて次第に狭くなっている。また、下側脚部２１の上端部には、上側脚部２２を支持する台座となる１対の突出部２６が設けられ、突出部２６の間には間隙が設けられている。突出部２６の上側からは、連結部２７が突出している。連結部２７は、上面に湾曲面を有する四角柱状に形成され、この湾曲面の底部には１つの連結孔２８が形成されている。連結孔２８の内側面には、雌螺子が形成されている。
Next, the support leg 15 will be described in detail with reference to FIGS.
As shown in FIG. 4, an adjuster 24 is provided at the lower end portion of the lower leg portion 21. The lower leg portion 21 is made of a single metal such as aluminum, or an alloy such as an aluminum alloy, a zinc alloy, a copper alloy, or a magnesium alloy, and is manufactured by die casting that presses molten metal into a mold. The lower leg portion 21 is curved between the upper end portion and the lower end portion thereof, and extends obliquely from the curved portion to the lower end portion. Moreover, the width H which is the length of the lower leg 21 in the direction orthogonal to the extending direction is gradually narrowed toward the lower end. In addition, a pair of projecting portions 26 serving as a pedestal for supporting the upper leg portion 22 is provided at the upper end portion of the lower leg portion 21, and a gap is provided between the projecting portions 26. A connecting portion 27 protrudes from the upper side of the protruding portion 26. The connecting portion 27 is formed in a quadrangular prism shape having a curved surface on the upper surface, and one connecting hole 28 is formed at the bottom of the curved surface. A female screw is formed on the inner surface of the connecting hole 28.
上側脚部２２は、２つの支柱３０を備えている。支柱３０は、金属管であって、アルミニウム、銅などの金属単体、又はアルミニウム合金、ステンレス、銅合金などの合金からなる。支柱３０は、略四角筒状に形成され、その内側に両端で開口する貫通孔３２を有している。支柱３０の一方の端部には、下側脚部２１の連結部２７が内嵌され、支柱３０の他方の端部は、１枚の支柱取付部３１を介してブラケット１３側に取り付けられる。 The upper leg 22 includes two struts 30. The support column 30 is a metal tube, and is made of a single metal such as aluminum or copper, or an alloy such as aluminum alloy, stainless steel, or copper alloy. The support column 30 is formed in a substantially rectangular tube shape, and has through-holes 32 opened at both ends on the inside thereof. A connecting portion 27 of the lower leg portion 21 is fitted into one end portion of the support column 30, and the other end portion of the support column 30 is attached to the bracket 13 side via a single support attachment portion 31.
支柱取付部３１は、略円盤状に形成され、支柱３０を取り付ける取付面には、支柱３０の他方の端部を内嵌する嵌合部３７が２箇所に設けられている。嵌合部３７の内側には、支柱３０に貫挿される貫挿ボルト３５を通すための挿通孔３３が設けられている。挿通孔３３は、支柱取付部３１の円形状の面の中心に対して対称となる位置にそれぞれ設けられている。貫挿ボルト３５の長さは、支柱よりも長く、その外周面には雄螺子が形成されている。また、支柱取付部３１には、支柱取付部３１をブラケット１３に固定するためのボルト４９を締結するための第１締結孔３４が形成されている。第１締結孔３４も、支柱取付部３１の円形状の面の中心に対して対称となる位置にそれぞれ設けられている。 The column attachment part 31 is formed in a substantially disk shape, and two fitting parts 37 for fitting the other end of the column 30 are provided on the attachment surface to which the column 30 is attached. Inside the fitting portion 37, an insertion hole 33 for passing the insertion bolt 35 inserted through the support column 30 is provided. The insertion holes 33 are respectively provided at positions that are symmetric with respect to the center of the circular surface of the column attachment portion 31. The length of the penetration bolt 35 is longer than that of the support column, and a male screw is formed on the outer peripheral surface thereof. Further, the column attachment portion 31 is formed with a first fastening hole 34 for fastening a bolt 49 for fixing the column attachment portion 31 to the bracket 13. The first fastening holes 34 are also provided at positions that are symmetrical with respect to the center of the circular surface of the column attachment portion 31.
ブラケット１３の脚取付部１４には、支柱取付部３１を取り付けるための３対の第２締結孔４０と、貫挿ボルト３５を通すための３対の取付孔４１とが設けられている。３対の取付孔４１のうち、いずれか１対を選択することによって、支柱取付部３１を回動させて、脚部２０の向きを変更させて固定する。 The leg attachment portion 14 of the bracket 13 is provided with three pairs of second fastening holes 40 for attaching the column attachment portions 31 and three pairs of attachment holes 41 for allowing the penetration bolts 35 to pass therethrough. By selecting any one of the three pairs of mounting holes 41, the column mounting portion 31 is rotated, and the direction of the leg portion 20 is changed and fixed.
図５に示すように、下側脚部２１は、その内側に凹部４７が形成されることで軽量化されている。凹部４７の中央には、下側脚部２１を補強するためのリブ４８が形成されている。また、下側脚部２１の下端に設けられた孔４６には、アジャスタ２４に支持されたボルト２９が螺合されている。支柱３０は、一方の端部を下側脚部２１の連結部２７に外嵌し、他方の端部を支柱取付部３１の嵌合部３７に外嵌することにより支柱取付部３１に固定される。このように支柱３０と下側脚部２１とを連結する連結部２７は露出されないので、見栄えをよくすることができる。 As shown in FIG. 5, the lower leg portion 21 is reduced in weight by forming a recess 47 inside thereof. A rib 48 for reinforcing the lower leg 21 is formed at the center of the recess 47. A bolt 29 supported by the adjuster 24 is screwed into a hole 46 provided at the lower end of the lower leg portion 21. The support column 30 is fixed to the support column attachment portion 31 by fitting one end portion of the support portion 27 to the lower leg portion 21 and fitting the other end portion to the engagement portion 37 of the support column attachment portion 31. The Thus, since the connection part 27 which connects the support | pillar 30 and the lower leg part 21 is not exposed, it can improve appearance.
また、脚部２０を、ブラケット１３の脚取付部１４に対して所望の向きで当接させ、ブラケット１３の裏面側から、１対の貫挿ボルト３５を脚取付部１４の取付孔４１に通す。さらに、貫挿ボルト３５を、支柱取付部３１の挿通孔３３、支柱３０の貫通孔３２、下側脚部２１の連結孔２８に順に通し、貫挿ボルト３５の雄螺子を連結孔２８の雌螺子に螺合する。このとき、貫挿ボルト３５の先端を、下側脚部２１の連結部２７に設けられた湾曲面に当接させることによって、この湾曲面の底部に設けられた連結孔２８に貫挿ボルト３５の先端を容易に導くことができる。また、支柱取付部３１の第１締結孔３４と、脚取付部１４の第２締結孔４０とにボルト４９が締結される。これにより、脚部２０がブラケット１３に対して取り付けられる。下側脚部２１及び上側脚部２２を連結したとき、支柱３０及び下側脚部２１の突出部２６は、ブラケット１３側から下方に延びる細長状の支持部３８を構成する。１対の支持部３８の間には間隙３９が設けられる。 Further, the leg portion 20 is brought into contact with the leg attachment portion 14 of the bracket 13 in a desired direction, and a pair of penetration bolts 35 are passed through the attachment holes 41 of the leg attachment portion 14 from the back surface side of the bracket 13. . Further, the penetration bolt 35 is passed through the insertion hole 33 of the support column mounting portion 31, the through hole 32 of the support column 30, and the connection hole 28 of the lower leg portion 21 in order. Screw into the screw. At this time, the tip of the penetrating bolt 35 is brought into contact with the curved surface provided on the connecting portion 27 of the lower leg 21, whereby the through-bolt 35 is inserted into the connecting hole 28 provided at the bottom of the curved surface. The tip of can be easily guided. In addition, a bolt 49 is fastened to the first fastening hole 34 of the column attachment part 31 and the second fastening hole 40 of the leg attachment part 14. Thereby, the leg portion 20 is attached to the bracket 13. When the lower leg portion 21 and the upper leg portion 22 are connected, the support 30 and the protruding portion 26 of the lower leg portion 21 constitute an elongated support portion 38 that extends downward from the bracket 13 side. A gap 39 is provided between the pair of support portions 38.
また、下側脚部２１の延在方向と、上側脚部２２の支柱３０の延在方向である鉛直方向とがなす角度θ２は、９０度超１８０度未満である。また、２つの支柱３０を含む面を、鉛直方向Ｚと水平方向Ｘとに平行なＺ−Ｘ面とするとき、下側脚部２１は、Ｚ−Ｘ面に含まれる。すなわち、下側脚部２１の延在方向は、２本の支柱３０が並ぶ面と平行である。 Further, the angle θ2 formed by the extending direction of the lower leg portion 21 and the vertical direction that is the extending direction of the support column 30 of the upper leg portion 22 is more than 90 degrees and less than 180 degrees. Further, when the plane including the two support columns 30 is a ZX plane parallel to the vertical direction Z and the horizontal direction X, the lower leg portion 21 is included in the ZX plane. That is, the extending direction of the lower leg portion 21 is parallel to the surface on which the two support columns 30 are arranged.
次に、支持脚１５の作用について説明する。
図５に示すように、上側脚部２２を構成する支柱３０は、金属管からなるため、支持脚全体をダイカストにより製造する場合よりも支持脚１５が軽量となる。一方、支持脚１５の一部である下側脚部２１はダイカストにより製造されるため、デザインの自由度を高めるとともに、支持脚１５全体をダイカストにより製造する場合に比べて金型を小さくすることができる。さらに、支柱３０を下側脚部２１によって下方から支持する構造とすることにより、例えば支持脚１５を支柱３０のみから構成する場合に比べ、強度を高めることができる。また、金属管からなる上側脚部２２とダイカスト品である下側脚部２１とを上下に連結するため、金属管とダイカスト品とを略Ｔ字状に組み合わせたりする場合に比べ、支持脚１５をスリムな形状とすることができる。このため、優れた外観とするとともに、ユーザの着座や退座などといった動作を極力妨げないようにすることができる。
Next, the operation of the support leg 15 will be described.
As shown in FIG. 5, since the support | pillar 30 which comprises the upper side leg part 22 consists of metal tubes, the support leg 15 becomes lightweight rather than the case where the whole support leg is manufactured by die-casting. On the other hand, since the lower leg portion 21 which is a part of the support leg 15 is manufactured by die casting, the degree of freedom in design is increased and the mold is made smaller than when the entire support leg 15 is manufactured by die casting. Can do. Furthermore, by adopting a structure in which the support column 30 is supported from below by the lower leg portion 21, for example, the strength can be increased as compared with the case where the support leg 15 is configured by only the support column 30. Further, since the upper leg portion 22 made of a metal tube and the lower leg portion 21 which is a die-cast product are connected vertically, the support leg 15 is compared with a case where the metal tube and the die-cast product are combined in a substantially T shape. Can be made slim. For this reason, while making it the outstanding external appearance, it can prevent the operation | movement, such as a user's seating and leaving, as much as possible.
また、下側脚部２１の突出部２６は、支持部３８の一部として支柱３０を下方から支持する。また、下側脚部２１及び上側脚部２２の連結部分は、支持部３８の下端部よりも鉛直方向上方にある。すなわち、天板１１の揺れなどによって水平方向にも荷重が加わる支持部３８の下端と、比較的脆弱である下側脚部２１及び上側脚部２２の連結部分とを異なる位置に設けることができるので、支持脚１５の強度を高めることができる。また、下側脚部２１は、２つの支柱３０と同じ面に含まれるように設けられる。下側脚部２１に上方から加えられた荷重は、下側脚部２１に対し、２つの支柱３０を含む面内において下側脚部２１の延在方向とは逆の方向に傾動させるように作用する。支柱３０は、下側脚部２１と同一面内において、下側脚部２１と脚取付部１４との間で下側脚部２１が傾かないように支持することができる。 Further, the protruding portion 26 of the lower leg portion 21 supports the support column 30 from below as a part of the support portion 38. Further, the connecting portion of the lower leg portion 21 and the upper leg portion 22 is above the lower end portion of the support portion 38 in the vertical direction. That is, the lower end of the support portion 38 to which a load is also applied in the horizontal direction due to shaking of the top plate 11 and the connecting portion of the lower leg portion 21 and the upper leg portion 22 that are relatively fragile can be provided at different positions. Therefore, the strength of the support leg 15 can be increased. Further, the lower leg portion 21 is provided so as to be included in the same surface as the two support columns 30. The load applied to the lower leg 21 from above is tilted in the direction opposite to the extending direction of the lower leg 21 in the plane including the two support columns 30 with respect to the lower leg 21. Works. The support column 30 can be supported in the same plane as the lower leg portion 21 so that the lower leg portion 21 does not tilt between the lower leg portion 21 and the leg mounting portion 14.

The three pairs of mounting holes 41 include a pair of first mounting holes 51, a pair of second mounting holes 52 provided in positions counterclockwise with respect to the first mounting hole 51, and a first It is divided into a pair of third mounting holes 53 provided at positions separated from the mounting holes 51 in the clockwise direction. That is, the leg portion 20 can be attached to the leg attachment portion 14 at three attachment angles.
１対の支持脚１５を、その下側脚部２１の延在方向がブラケット１３の長手方向と平行となるように設けるとき（図３参照）、第１取付孔５１と、支柱取付部３１の挿通孔３３とを一致させる。そして、貫挿ボルト３５を、位置を一致させた挿通孔３３及び第１取付孔５１に通す。また、１対の支持脚１５を、その下側脚部２１の延在方向がブラケット１３の長手方向と交差するように設けるとき（図６参照）、第２取付孔５２と支柱取付部３１の挿通孔３３とを一致させるか、又は、第３取付孔５３と支柱取付部３１の挿通孔３３とを一致させる。第２取付孔５２及び第３取付孔５３のいずれを挿通孔３３と一致させるかは、天板１１に対する脚部２０の位置に応じて選択すればよい。このように脚取付部１４に対する脚部２０の角度を変更可能とすることにより、脚部２０をテーブルの用途に合わせた向きで取り付けることができる。 When the pair of support legs 15 is provided so that the extending direction of the lower leg portion 21 is parallel to the longitudinal direction of the bracket 13 (see FIG. 3), the first attachment hole 51 and the column attachment portion 31 The insertion hole 33 is matched. Then, the penetration bolt 35 is passed through the insertion hole 33 and the first attachment hole 51 whose positions are matched. Further, when the pair of support legs 15 is provided so that the extending direction of the lower leg portion 21 intersects the longitudinal direction of the bracket 13 (see FIG. 6), the second attachment hole 52 and the column attachment portion 31 are provided. The insertion hole 33 is made to coincide, or the third attachment hole 53 and the insertion hole 33 of the column attachment part 31 are made to coincide. Which of the second mounting hole 52 and the third mounting hole 53 coincides with the insertion hole 33 may be selected according to the position of the leg portion 20 with respect to the top plate 11. In this way, by making it possible to change the angle of the leg portion 20 with respect to the leg attachment portion 14, the leg portion 20 can be attached in an orientation that matches the application of the table.
