本発明は、天板１を脚体２で支持したテーブルやデスクにおける脚体と天板ブラケットの連結構造であって、前記脚体２は、前記天板１の下面に沿う脚横桟４の両端部に脚縦支柱５，５の上端部を嵌合して構成し、前記天板１の下面に取付ける天板ブラケット３を前記脚横桟４と脚縦支柱５の接合部９を跨いで両部材にネジ止めして連結状態としたことを特徴とする。本実施形態では、本発明をテーブルに適用した例で説明するが、デスクであても良く、またその他の天板を脚体で支持する家具や什器であっても構わない。 The present invention relates to a connecting structure of a leg and a top plate bracket in a table or desk in which the top 1 is supported by the legs 2, wherein the leg 2 is a leg crosspiece 4 along the lower surface of the top 1. The top plate bracket 3 attached to the lower surface of the top plate 1 is formed by fitting the upper end portions of the leg vertical supports 5 and 5 at both ends, and straddling the joint portion 9 of the leg horizontal cross 4 and the leg vertical support 5 It is characterized by screwing to both members and making it a connected state. In the present embodiment, although the present invention is applied to a table, the present invention may be applied to a desk, or may be furniture or furniture that supports other top plates with legs.

先ず、図１〜図４に基づいて第１実施形態のテーブルＡを説明する。前記脚体２の脚横桟４は少なくとも両端部の筒状の嵌合凹部１０を有し、前記脚縦支柱５は上端部に水平方向を向いた嵌合凸部１１を有し、前記脚横桟４の嵌合凹部１０に前記脚縦支柱５の嵌合凸部１１を嵌入した状態で、前記天板ブラケット３は、前記脚横桟４の端部に前記嵌合凸部１１に形成した螺孔を用いてネジ止めするとともに、前記脚縦支柱５の上端部に形成した螺孔を用いてネジ止めしてなる連結構造とした。本実施形態では、前記天板ブラケット３として支持ブラケット６を用いて天板１と脚体２を連結する。 First, the table A of the first embodiment will be described based on FIGS. 1 to 4. The leg crosspiece 4 of the leg 2 has a cylindrical fitting recess 10 at least at both ends, and the leg vertical support 5 has a fitting protrusion 11 directed horizontally at the upper end, the leg The top plate bracket 3 is formed in the fitting convex portion 11 at the end portion of the leg lateral bar 4 in a state where the fitting convex portion 11 of the leg vertical support 5 is fitted into the fitting concave portion 10 of the horizontal bar 4. While being screwed using the screw hole which was carried out, it was set as the connection structure formed by screwing using the screw hole formed in the upper end part of the said leg vertical post 5. In the present embodiment, the top plate 1 and the leg 2 are connected using the support bracket 6 as the top plate bracket 3.

具体的には、前記脚縦支柱５の嵌合凸部１１の両側面に螺孔１２を形成するとともに、嵌合凸部１１の上面の先端部に螺孔１３，１３を並設し、更に前記脚縦支柱５の上端部の上面に螺孔１４，１４を並設している。ここで、前記脚横桟４は四角筒状の部材であり、端部が嵌合凹部１０，１０となっており、前記脚縦支柱５は、アルミダイカスト製で上端部にエルボー部１５を設け、該エルボー部１５に前記嵌合凸部１１を設けている。つまり、前記螺孔１４，１４は、前記エルボー部１５の上面に形成している。前記脚横桟４には、前記螺孔１２に対応する側面位置に通孔１６、前記螺孔１３，１３に対応する上面位置に通孔１７，１７をそれぞれ形成している。 Specifically, screw holes 12 are formed on both sides of the fitting convex portion 11 of the leg vertical support 5, and screw holes 13 and 13 are provided in parallel at the tip of the upper surface of the fitting convex portion 11, Screw holes 14 are arranged in parallel on the upper surface of the upper end portion of the leg vertical support 5. Here, the leg crosspiece 4 is a square cylindrical member, and the end portions thereof are fitting recesses 10 and 10, and the leg vertical support 5 is made of an aluminum die-cast and provided with an elbow portion 15 at the upper end. The fitting convex portion 11 is provided on the elbow portion 15. That is, the screw holes 14 and 14 are formed on the upper surface of the elbow portion 15. Through holes 16 are formed at side positions corresponding to the screw holes 12 and through holes 17, 17 are formed at upper surface positions corresponding to the screw holes 13, 13 in the leg cross rail 4, respectively.

前記脚縦支柱５に形成する螺孔は、前記脚横桟４に隠れる嵌合凸部１１と目立たない上端部にのみ形成すれば良く、それにより脚縦支柱５の上端部の側面には螺孔を形成する必要がないので、脚縦支柱５を左右対称に作製しても外側面に螺孔が露出しない。つまり、同一の脚縦支柱５を前後左右共通で使用できる。また、前記脚横桟４は、両端部は対称形であるので、前記通孔１６を片面のみ形成したものと、両面に形成したものの２種類用意すれば、外側面に使用しない通孔１６が露出することはない。そして、前記脚横桟４を２種類用意しても、筒状部材であり、穴あけ加工だけであるので、大きなコスト高にならない。 The screw holes formed in the leg vertical support 5 may be formed only in the fitting convex portion 11 hidden in the leg crosspiece 4 and the inconspicuous upper end, whereby the side surface of the upper end of the leg vertical support 5 is screwed Since it is not necessary to form a hole, the screw hole is not exposed on the outer side surface even if the leg vertical support 5 is made symmetrical. That is, the same leg vertical support 5 can be used in common to the front and rear, right and left. Further, since the leg crosspiece 4 is symmetrical at both ends, if the through hole 16 is formed on only one side or in both sides, the through hole 16 not used on the outer surface is prepared. It will not be exposed. And even if two types of said leg cross bars 4 are prepared, since it is a cylindrical member and it is only a drilling process, it does not become big cost increase.

前記支持ブラケット６は、天板１の下面に取付ける受板１８の下面で一側端からやや中央寄り位置に垂直部１９を設け、該垂直部１９から外側の受板１８の一部を水平部２０とし、前記脚体２の脚横桟４の側面に前記垂直部１９がネジ止め可能であるとともに、前記脚縦支柱５の上端部の上面と前記脚横桟４の上面とに前記水平部２０がネジ止め可能である。 The support bracket 6 is provided on the lower surface of the support plate 18 attached to the lower surface of the top plate 1 with a vertical portion 19 at a position slightly closer to the center from one side end. 20, the vertical portion 19 can be screwed to the side surface of the leg cross rail 4 of the leg 2, and the horizontal portion on the upper surface of the upper end portion of the leg vertical support 5 and the upper surface of the leg cross rail 4 20 are screwable.

具体的には、前記支持ブラケット６は、図４に示すように、合成樹脂製好ましくは強度の点でアルミダイカスト製の成形品とし、前記天板１の下面に当接する平面視略四角形の受板１８の下面に正面視三角形状の突出部２１の切り立った側面を前記垂直部１９としている。そして、前記垂直部１９には連結孔２２を形成し、前記水平部２０の両側部にも連結孔２３，２３を形成するとともに、両連結孔２３，２３の中間に下方へ突出したダボ２４を形成し、そして前記受板１８で前記水平部２０とは異なる位置に複数の通孔２５，…を形成している。尚、前記水平部２０の横幅（左右方向の幅）は、前記脚体２の上部の厚み、つまり前記脚横桟４の上面の幅の１／２以下とする。 Specifically, as shown in FIG. 4, the support bracket 6 is made of a synthetic resin, preferably an aluminum die-cast molded product in terms of strength, and the support bracket 6 has a substantially rectangular shape in plan view abutting on the lower surface of the top plate 1. On the lower surface of the plate 18, a side surface of the protrusion 21 having a triangular shape in a front view is referred to as the vertical portion 19. Then, a connecting hole 22 is formed in the vertical portion 19, and connecting holes 23, 23 are also formed in both side portions of the horizontal portion 20, and a dowel 24 projecting downward to the middle between both connecting holes 23, 23 is formed.
