Description

本発明は、テーブルの脚装置に係わり、更に詳しくは天板の下面に脚ブラケットを介して脚柱を取付けた構造のテーブルにおける脚装置に関するものである。   The present invention relates to a table leg device, and more particularly to a leg device in a table having a structure in which a pedestal is attached to a lower surface of a top plate via a leg bracket.

従来から、天板の下面を複数の脚柱で脚ブラケットを介して支持したテーブルは各種提供されている。例えば、平面視四角形の天板では、下面の四隅に脚柱を固定する脚ブラケットを取付けるとともに、隣接する両側の脚ブラケットの間にビームを連結し、該ビームを天板下面に固定して脚柱の取付強度の向上と天板の補強を行っている。   Conventionally, various tables have been provided in which the lower surface of the top plate is supported by a plurality of pedestals via leg brackets. For example, in the case of a top plate having a rectangular shape in plan view, leg brackets are fixed to the four corners of the lower surface, a beam is connected between the adjacent leg brackets on both sides, and the beam is fixed to the lower surface of the top plate. The column mounting strength is improved and the top plate is reinforced.

特許文献１には、連結体には、脚支柱の支持部と反対側にて互いに９０度の向きを変えて開口するような上向き開放溝状の一対の横梁支持部が形成され、各横梁支持部には底から上向きにボス部を突出形成し、断面中空矩形状の各横梁の端部の端部には、ボス部と同じ断面形状の丸孔が下面側に穿設されており、各横梁を横梁支持部の溝内に上方から嵌合するとともに、ボス部を丸孔に受け入れ、その上面側からボス部にネジ止め固定し、それから天板を横梁及び連結体の上に載せ、横梁の下面側及び連結体の下面側から天板にそれぞれネジ止めする構造が記載されている。   In Patent Document 1, a pair of cross beam support portions in the form of upward open grooves are formed in the connecting body so as to open at opposite sides of the support portions of the leg struts by 90 degrees. A boss part is formed so as to protrude upward from the bottom, and a round hole having the same cross-sectional shape as the boss part is formed on the lower surface side at the end part of each cross beam with a rectangular cross section. The transverse beam is fitted into the groove of the transverse beam support part from above, the boss part is received in the round hole, screwed and fixed to the boss part from the upper surface side, and then the top plate is placed on the transverse beam and the coupling body. The structure which screws to a top plate from the lower surface side of this and the lower surface side of a coupling body, respectively is described.

特許文献２には、左右に離間して配置した複数の支持脚を連結杆で連結することにより形成したベース部の上方に天板を設けてなるデスクにおいて、支持脚の上端部にジョイント材を取付け、管材によって形成した連結杆に前記ジョイント材を内嵌させ、ジョイント材及び連結杆に形成した上下方向の挿通孔に上方から固定ねじを挿通し、連結杆の下面側に当接させた連結支持具のねじ孔に螺合して、連結杆を支持脚に対して固定し、そして支持脚と連結杆に天板を載せて、下方から前記連結杆とジョイント材を貫通した固定ねじを天板の下面のねじ孔に螺合して連結する構造が記載されている。ここで、前記連結杆の上面に突出した固定ねじの頭部を受け入れる挿入孔を、前記天板の下面に予め形成されている点も記載されている。   In Patent Document 2, in a desk in which a top plate is provided above a base portion formed by connecting a plurality of support legs spaced apart from each other with a connecting rod, a joint material is provided on the upper end portion of the support legs. The connection is made by fitting the joint material into a connecting rod formed by mounting and pipe material, inserting a fixing screw from above into the vertical insertion hole formed in the joint material and the connecting rod, and contacting the lower surface side of the connecting rod The connection rod is fixed to the support leg by screwing into the screw hole of the support tool, and the top plate is placed on the support leg and the connection rod, and the fixing screw penetrating the connection rod and the joint material from below is fixed to the ceiling. A structure is described in which the screw hole is connected to the screw hole on the lower surface of the plate. Here, it is also described that an insertion hole for receiving the head of the fixing screw protruding from the upper surface of the connecting rod is formed in advance on the lower surface of the top plate.

しかし、前述の特許文献に記載のものは、脚ブラケット（連結体、ジョイント材）にビーム（横梁、連結杆）を連結する場合、両部材を嵌合した上で上方から第１のネジで固定した後、天板を載置して、一方の部材又は両部材を貫通するように下方から第２のネジを天板下面に螺合する構造であり、ネジ止め作業に手間がかかるとともに、構造上、第１のネジと第２のネジは異なる長さのものを使用することになり、部品の種類が増えてコスト高となる傾向がある。尚、脚ブラケットと天板にそれぞれ螺孔を形成し、１本の固定ネジで脚ブラケットとビームと天板を共締めする場合、各部材の加工精度、螺孔の凹凸ピッチの不一致等の要因で、天板がビームや脚ブラケットから浮き上がる場合があり、品質が不安定、連結強度不足の問題が生じる。また、天板のみに螺孔を形成し、他の部材には貫通孔を形成し、１本の固定ネジで三部材を共締めする場合、ビームと脚ブラケットとの連結強度が不足し、貫通孔と固定ネジの間のクリアランスのためガタツキが生じる。   However, in the above-mentioned patent document, when a beam (horizontal beam, connecting rod) is connected to a leg bracket (connecting body, joint material), both members are fitted and fixed with the first screw from above. After that, the top plate is placed, and the second screw is screwed to the lower surface of the top plate from below so as to penetrate one member or both members. In addition, the first screw and the second screw have different lengths, and there is a tendency that the types of parts increase and the cost increases. In addition, when screw holes are formed in the leg bracket and the top plate, respectively, and the leg bracket, beam, and top plate are fastened together with a single fixing screw, factors such as inconsistency in machining accuracy of each member and uneven pitch of the screw holes In some cases, the top plate may be lifted from the beam or the leg bracket, resulting in unstable quality and insufficient connection strength. In addition, when only the top plate is formed with a screw hole, the other member is formed with a through hole, and the three members are fastened together with a single fixing screw, the connection strength between the beam and the leg bracket is insufficient. A backlash occurs due to the clearance between the hole and the fixing screw.
