　上記のような支持脚を有する天板付什器において、例えば、天板や支持脚に外力が加わった場合、支持脚は、脚接続部に接続された上端部側を中心として、支持脚の延伸方向に交差する方向に変形することがある。すると、支持脚の上端部と脚接続部との接続部分に、力（モーメント）が集中して作用する。
　これに対し、支持脚の上端部と脚接続部とを、さらに強固に接続しようとすると、支持脚と脚接続部との接続部分の大型化、構造の複雑化に繋がる可能性がある。
　本発明は、支持脚の上端部の接続強度を効率的に高めることができる天板付什器を提供することを目的とする。 In the furniture with the top plate having the support legs as described above, for example, when an external force is applied to the top plate or the support legs, the support legs are centered on the upper end side connected to the leg connection portion and the extending direction of the support legs. It may be deformed in the direction intersecting with. Then, the force (moment) concentrates and acts on the connecting portion between the upper end portion of the supporting leg and the leg connecting portion.
On the other hand, if the upper end portion of the support leg and the leg connecting portion are to be connected more firmly, the connecting portion between the support leg and the leg connecting portion may be increased in size and the structure may be complicated.
An object of the present invention is to provide a furniture with a ceiling plate that can efficiently increase the connection strength of the upper ends of the support legs.

　接続凸部４１は、支持脚４０の上端部４０ａに設けられている。接続凸部４１は、支持脚本体４２から上方に向けて直線状に突出している。接続凸部４１は、ブラケット３０の支持脚挿入凹部３３に挿入される。 The connection convex portion 41 is provided on the upper end portion 40 a of the support leg 40. The connection convex portion 41 linearly projects upward from the support leg main body 42. The connection protrusion 41 is inserted into the support leg insertion recess 33 of the bracket 30.
　接続凸部４１は、支持脚挿入凹部３３に補形する断面形状を有している。接続凸部４１は、上下方向に同一断面形状を有して延びている。接続凸部４１は、一対の凸部側面４１ａと、凸部内側面（直交側面）４１ｂと、凸部外側面４１ｃと、上端面４１ｔと、を有する。 The connecting convex portion 41 has a sectional shape that complements the supporting leg insertion concave portion 33.

The connecting convex portion 41 has a pair of convex side surfaces 41a, a convex inner surface (orthogonal side surface) 41b, a convex outer surface 41c, and an upper end surface 41t.
　一対の凸部側面４１ａは、内外方向Ｄ３に沿って互いに平行に設けられている。
　凸部内側面４１ｂは、一対の凸部側面４１ａの一方の端部（内外方向Ｄ３における内側端部）同士を連結するよう形成されている。凸部外側面４１ｃは、一対の凸部側面４１ａの他方の端部（内外方向Ｄ３における外側端部）同士を連結するよう形成されている。凸部外側面４１ｃは、上方から見て、内外方向Ｄ３における外側Ｄｏに凸の円弧状に湾曲している。
　上端面４１ｔは、上下方向に直交して形成されている。 The pair of convex side surfaces 41a are provided in parallel with each other along the inner-outer direction D3.
The convex inner surface 41b is formed so as to connect one end (inner end in the inward / outward direction D3) of the pair of convex side surfaces 41a. The convex outer surface 41c is formed so as to connect the other ends of the pair of convex side surfaces 41a (outer ends in the inward / outward direction D3). When viewed from above, the convex outer surface 41c is curved in an arc shape that is convex toward the outer side Do in the inner-outer direction D3.
The upper end surface 41t is formed orthogonal to the vertical direction.
　接続凸部４１の上端面４１ｔには、複数個所に、第一雌ネジ孔４５が開口している。また、接続凸部４１の凸部内側面４１ｂには、第二雌ネジ孔４６が開口している。 The first female screw holes 45 are opened at a plurality of locations on the upper end surface 41t of the connecting convex portion 41. Further, a second female screw hole 46 is opened on the inner surface 41 b of the protrusion of the connection protrusion 41.
　このような接続凸部４１は、ブラケット３０の支持脚挿入凹部３３に挿入される。接続凸部４１は、支持脚挿入凹部３３内で突出部３２に接続される。すなわち、接続凸部４１は、下端面３４よりも上方位置で突出部３２に接続される。 Such a connection convex portion 41 is inserted into the support leg insertion concave portion 33 of the bracket 30. The connection protrusion 41 is connected to the protrusion 32 in the support leg insertion recess 33. That is, the connection protrusion 41 is connected to the protrusion 32 at a position above the lower end surface 34.
　図６、図７に示すように、支持脚４０の接続凸部４１には、支持脚挿入凹部３３に挿入された状態で、上下方向に延びる第一支持脚締結ボルト６２が締結される。第一支持脚締結ボルト６２は、ブラケット３０の第一面３１ｓから下方に向かって延びる。第一支持脚締結ボルト６２は、第一ボルト挿通孔３５を通して、第一雌ネジ孔４５に締結される。このように、第一支持脚締結ボルト６２が締結された状態で、支持脚４０の上端部４０ａの上端面４１ｔと、支持脚挿入凹部３３において上端面４１ｔに対向する頂面３３ｅとは、互いに突き当たっている。なお、支持脚４０の上端面４１ｔと、支持脚挿入凹部３３において上端面４１ｔに対向する頂面３３ｅとは、上下方向で離間していてもよい。 As shown in FIGS. 6 and 7, a first support leg fastening bolt 62 extending in the up-down direction is fastened to the connection convex portion 41 of the support leg 40 while being inserted into the support leg insertion concave portion 33. The first support leg fastening bolt 62 extends downward from the first surface 31s of the bracket 30. The first support leg fastening bolt 62 is fastened to the first female screw hole 45 through the first bolt insertion hole 35. Thus, in the state where the first support leg fastening bolt 62 is fastened, the upper end surface 41t of the upper end portion 40a of the support leg 40 and the top surface 33e of the support leg insertion recess 33 that faces the upper end surface 41t are opposite to each other. I'm hitting. The upper end surface 41t of the support leg 40 and the top surface 33e of the support leg insertion recess 33 that faces the upper end surface 41t may be separated in the vertical direction.
　また、接続凸部４１には、支持脚挿入凹部３３に挿入された状態で、第二支持脚締結ボルト６３が締結される。第二支持脚締結ボルト６３は、突出部３２においてフレーム２０の内外方向Ｄ３の内側を向く側に設けられている。第二支持脚締結ボルト６３は、突出部３２の内側凹湾曲面３２ｂから、第一支持脚締結ボルト６２が延びる方向と交差する内外方向Ｄ３に延びる。第二支持脚締結ボルト６３は、第二ボルト挿通孔３６を通して、第二雌ネジ孔４６に締結される。このように、第二支持脚締結ボルト６３が締結された状態で、接続凸部４１の凸部内側面４１ｂと、支持脚挿入凹部３３の内側壁面３３ｂは、第二支持脚締結ボルト６３が延びる方向（内外方向Ｄ３）に直交して互いに突き当たっている。
なお、接続凸部４１の凸部内側面４１ｂと、支持脚挿入凹部３３の内側壁面３３ｂは、内外方向Ｄ３で離間していてもよい。 Also, the second support leg fastening bolt 63 is fastened to the connection convex portion 41 while being inserted into the support leg insertion concave portion 33. The second support leg fastening bolt 63 is provided on the side of the protrusion 32 that faces the inside in the inward / outward direction D3 of the frame 20. The second support leg fastening bolt 63 extends from the inner concave curved surface 32b of the protruding portion 32 in an inward / outward direction D3 that intersects the direction in which the first support leg fastening bolt 62 extends. The second support leg fastening bolt 63 is fastened to the second female screw hole 46 through the second bolt insertion hole 36. As described above, in the state where the second support leg fastening bolt 63 is fastened, the convex inner surface 41b of the connection convex portion 41 and the inner wall surface 33b of the support leg insertion concave portion 33 are arranged in a direction in which the second support leg fastening bolt 63 extends. They are in contact with each other at right angles to the (inward / outward direction D3).
The convex inner surface 41b of the connecting convex portion 41 and the inner wall surface 33b of the support leg insertion concave portion 33 may be separated from each other in the inward / outward direction D3.
　このように、支持脚４０の上端部４０ａは、上記ブラケット３０を介してフレーム２０の角部２０ｃに接続されている。支持脚４０の接続凸部４１は、支持脚挿入凹部３３の頂面３３ｅと、内側壁面３３ｂとの二面に突き当たって固定されている。 In this way, the upper end portion 40a of the support leg 40 is connected to the corner portion 20c of the frame 20 via the bracket 30. The connection convex portion 41 of the support leg 40 is fixed by abutting on two surfaces of the top surface 33e of the support leg insertion concave portion 33 and the inner wall surface 33b.
　図７、図８に示すように、支持脚４０は、支持脚本体４２の上端面４３は、接続凸部４１の下端から水平方向（側方）に張り出している。支持脚本体４２の上端面４３は、上下方向に直交して上方を向く平面状である。支持脚本体４２の上端面４３は、接続凸部４１の周囲を全周に亘って取り囲むように形成されている。したがって、接続凸部４１の外周面及び支持脚本体４２の上端面４３で囲まれた部分は、上方及び水平方向に開放された段部を構成している。上端面４３は、支持脚側内側端面４３ａと、支持脚側外側端面４３ｂと、支持脚側部端面４３ｃと、を有する。 As shown in FIGS. 7 and 8, in the support leg 40, the upper end surface 43 of the support leg main body 42 projects horizontally (sideways) from the lower end of the connection convex portion 41. The upper end surface 43 of the support leg main body 42 has a planar shape that is orthogonal to the vertical direction and faces upward. The upper end surface 43 of the support leg main body 42 is formed so as to surround the entire circumference of the connection convex portion 41. Therefore, the portion surrounded by the outer peripheral surface of the connection convex portion 41 and the upper end surface 43 of the support leg main body 42 constitutes a step portion that is open in the upper and horizontal directions. The upper end surface 43 has a support leg side inner end surface 43a, a support leg side outer end surface 43b, and a support leg side portion end surface 43c.
　支持脚側内側端面４３ａは、接続凸部４１に対し、内外方向Ｄ３の内側に位置している。支持脚側内側端面４３ａは、内側端面３４ａの下方に位置している。 The support leg-side inner end surface 43a is located inside the connection convex portion 41 in the inward / outward direction D3. The support leg side inner end surface 43a is located below the inner end surface 34a.

　支持脚側外側端面４３ｂは、接続凸部４１に対し、内外方向Ｄ３の外側Ｄｏに位置している。支持脚側外側端面４３ｂは、外側端面３４ｂの下方に位置している。
The support leg side outer end surface 43b is located on the outer side Do in the inner-outer direction D3 with respect to the connection convex portion 41. The support leg side outer end surface 43b is located below the outer end surface 34b.
　支持脚側部端面４３ｃは、水平面内で内外方向Ｄ３に直交する方向において接続凸部４１の両側に形成されている。支持脚側部端面４３ｃは、側部端面３４ｃの下方に位置している。 The support leg side end face 43c is formed on both sides of the connecting protrusion 41 in the direction orthogonal to the inward / outward direction D3 in the horizontal plane. The support leg side end surface 43c is located below the side end surface 34c.
　本実施形態において、支持脚側内側端面４３ａは、支持脚側外側端面４３ｂよりも、面積が大きく形成されている。但し、支持脚側内側端面４３ａ、支持脚側外側端面４３ｂ、及び支持脚側部端面４３ｃの面積は、適宜変更が可能である。なお、本実施形態において、支持脚本体４２の上端面４３の面積は、突出部３２の下端面３４の面積よりも大きくなっている。 In the present embodiment, the support leg side inner end surface 43a is formed to have a larger area than the support leg side outer end surface 43b. However, the areas of the support leg side inner end surface 43a, the support leg side outer end surface 43b, and the support leg side portion end surface 43c can be appropriately changed. In this embodiment, the area of the upper end surface 43 of the support leg body 42 is larger than the area of the lower end surface 34 of the protrusion 32.
　このように、支持脚本体４２の上端面４３は、突出部３２の下端面３４の上下方向で対向（近接または当接）している。本実施形態では、支持脚本体４２の上端面４３は、接続凸部４１の全周に亘って突出部３２の下端面３４に下方から当接している。但し、支持脚本体４２の上端面４３は、接続凸部４１の全周に亘って突出部３２の下端面３４に近接する構成であってもよい。この場合、支持脚本体４２の上端面４３と、突出部３２の下端面３４と、の上下方向の間隔は、天板付什器１に作用する外力によって支持脚４０が弾性変形した場合に、上端面４３と下端面３４とが突き当たるように設定されていることが好ましい。このような間隔としては、例えば数ｍｍ以下とするのが好ましい。 In this way, the upper end surface 43 of the support leg body 42 opposes (approaches or abuts) the lower end surface 34 of the protrusion 32 in the up-down direction. In the present embodiment, the upper end surface 43 of the support leg main body 42 is in contact with the lower end surface 34 of the projecting portion 32 from below over the entire circumference of the connecting convex portion 41. However, the upper end surface 43 of the support leg body 42 may be configured to be close to the lower end surface 34 of the projecting portion 32 over the entire circumference of the connecting convex portion 41. In this case, the vertical interval between the upper end surface 43 of the support leg main body 42 and the lower end surface 34 of the protrusion 32 is determined by the upper end surface when the support leg 40 is elastically deformed by an external force acting on the top plate fixture 1. It is preferable to set so that 43 and the lower end surface 34 abut. It is preferable that such an interval is, for example, several mm or less.
　なお、支持脚本体４２の上端面４３は、突出部３２の下端面３４に少なくとも一部で当接するような構成であってもよい。例えば、支持脚本体４２の上端面４３及び突出部３２の下端面３４のうち、面積の大きい支持脚側内側端面４３ａ及び内側端面３４ａのみが当接するようにしてもよい。 The upper end surface 43 of the support leg body 42 may be in contact with the lower end surface 34 of the protrusion 32 at least partially. For example, among the upper end surface 43 of the support leg main body 42 and the lower end surface 34 of the protrusion 32, only the support leg side inner end surface 43a and the inner end surface 34a having a large area may be in contact.
　次に、支持脚４０の傾斜角度が変化するような外力が、天板付什器１に加わった場合の作用について説明する。ここで、支持脚４０において、上端部４０ａに対して下端部４０ｂが内外方向Ｄ３における外側Ｄｏに傾斜した支持脚本体４２の中心軸Ｃ２（支持脚本体４２における平面視での中心を通り、支持脚本体４２の延在方向に延びる軸）の、上下方向Ｄｖに対する角度を、支持脚４０の傾斜角度θとする。 Next, the operation when an external force that changes the inclination angle of the support leg 40 is applied to the furniture 1 with the top plate will be described. Here, in the support leg 40, the lower end portion 40b is inclined with respect to the upper end portion 40a toward the outer side Do in the inward and outward direction D3, and the central axis C2 of the support leg body 42 (passes through the center of the support leg body 42 in plan view and is The angle of the axis extending in the extending direction of the leg body 42) with respect to the up-down direction Dv is the inclination angle θ of the support leg 40.
　図９は、上記天板支持体に、支持脚４０の傾斜角度θが小さくなる方向の外力Ｆ１が加わった場合の作用を示す図である。
　図９に示すように、天板付什器１に対し、内外方向（第１方向）Ｄ３における外側（他方側）Ｄｏに向かう外力Ｆ１が加わった場合について検討する。この場合、外力Ｆ１により、支持脚４０は、上端部４０ａに対し、下端部４０ｂが、支持脚本体４２の延在方向（中心軸Ｃ２方向）と交差する方向（内外方向Ｄ３）において、外力Ｆ１と反対方向Ｘ１に相対的に変位しようとする。これにより、支持脚４０の上端部４０ａには、支持脚４０の傾斜角度θが小さくなる方向のモーメントＭ１が作用する。 FIG. 9 is a diagram showing an operation when an external force F1 in a direction in which the inclination angle θ of the support leg 40 is reduced is applied to the top plate support.
As shown in FIG. 9, a case where an external force F1 toward the outside (the other side) Do in the inside / outside direction (first direction) D3 is applied to the furniture 1 with the top plate will be examined. In this case, due to the external force F1, the support leg 40 has an external force F1 with respect to the upper end portion 40a in a direction (inward / outward direction D3) in which the lower end portion 40b intersects the extending direction (the central axis C2 direction) of the support leg body 42. And relatively displaces in the opposite direction X1. As a result, the moment M1 in the direction in which the inclination angle θ of the support leg 40 becomes smaller acts on the upper end portion 40a of the support leg 40.
　この場合、本実施形態では、突出部３２の下端面３４及び支持脚本体４２の上端面４３のうち、内外方向Ｄ３の内側に位置する部分（内側端面３４ａと支持脚側内側端面４３ａ）同士が突き当たっているため、モーメントＭ１による支持脚４０の変形荷重が内側端面３４ａによって受け止められる。 In this case, in the present embodiment, of the lower end surface 34 of the protrusion 32 and the upper end surface 43 of the support leg main body 42, the portions located inside the inner / outer direction D3 (the inner end surface 34a and the support leg side inner end surface 43a) are adjacent to each other. Since they abut, the deformation load of the support leg 40 due to the moment M1 is received by the inner end surface 34a.
　図１０は、上記天板支持体に、支持脚４０の傾斜が大きくなる方向の外力Ｆ２が加わった場合の作用を示す図である。
　図１０に示すように、天板付什器１に対し、内外方向Ｄ３における内側（一方側）に向かう外力Ｆ２が加わった場合、外力Ｆ２により、支持脚４０は、上端部４０ａに対し、下端部４０ｂが、支持脚本体４２の延在方向と交差する方向において、外力Ｆ２と反対方向Ｘ２に相対的に変位しようとする。これにより、支持脚４０の上端部４０ａには、支持脚４０の傾斜角度θが大きくなる方向のモーメントＭ２が作用する。 FIG. 10 is a diagram showing an operation when an external force F2 in a direction in which the inclination of the support leg 40 is increased is applied to the top plate support.
As shown in FIG. 10, when an external force F2 directed inward (one side) in the inward / outward direction D3 is applied to the furniture 1 with the top plate, the supporting leg 40 causes the upper end 40a to move toward the lower end 40b by the external force F2. However, in the direction crossing the extending direction of the support leg main body 42, it tends to relatively displace in the opposite direction X2 to the external force F2. As a result, the moment M2 in the direction in which the inclination angle θ of the support leg 40 increases is applied to the upper end portion 40a of the support leg 40.
　この場合、本実施形態では、突出部３２の下端面３４及び支持脚本体４２の上端面４３のうち、内外方向Ｄ３の外側Ｄｏに位置する部分（外側端面３４ｂと支持脚側外側端面４３ｂ）同士が突き当たっているため、モーメントＭ２による支持脚４０の変形荷重が内側端面３４ａによって受け止められる。 In this case, in the present embodiment, of the lower end surface 34 of the protrusion 32 and the upper end surface 43 of the support leg main body 42, the portions located on the outer side Do in the inner-outer direction D3 (the outer end surface 34b and the support leg-side outer end surface 43b). Are abutted against each other, the deformation load of the support leg 40 due to the moment M2 is received by the inner end surface 34a.
　なお、支持脚４０が内外方向Ｄ３で対向して配置される場合には、内外方向Ｄ３で対向する支持脚４０のうち、一方の支持脚４０については傾斜角度θが小さくなる方向に変形しようとし、他方の支持脚４０については傾斜角度θが大きくなる方向に変形しようとする。この場合において、一方の支持脚４０では、内外方向Ｄ３の外側で下端面３４及び上端面４３が突き当たり、他方の支持脚４０では、内外方向Ｄ３の内側で下端面３４及び上端面４３が突き当たる。これにより、何れの方向に外力が作用した場合であっても、支持脚４０の過度な変形を抑制できる。 When the support legs 40 are arranged so as to face each other in the inward / outward direction D3, one of the support legs 40 facing in the inward / outward direction D3 is about to be deformed in a direction in which the inclination angle θ decreases. The other supporting leg 40 tends to be deformed in the direction in which the inclination angle θ increases. In this case, in one support leg 40, the lower end surface 34 and the upper end surface 43 abut outside the inner / outer direction D3, and in the other support leg 40, the lower end surface 34 and the upper end surface 43 abut inside the inner / outer direction D3. As a result, it is possible to suppress the excessive deformation of the support leg 40 regardless of which direction the external force acts.
　本実施形態では、支持脚４０の接続凸部４１は、天板２の下面２ｂに設けられたブラケット３０の突出部３２に対して下端面３４よりも上方でブラケット３０に接続される。支持脚本体４２の上端面４３は、突出部３２の下端面３４に上下方向で対向している。
　このような構成によれば、例えば外力Ｆ１，Ｆ２によって支持脚４０が弾性変形し、上端面４３が下端面３４に突き当たると、支持脚４０の変形荷重が下端面３４によって受け止められる。これにより、支持脚４０の傾斜角度θが変化する方向における過度な変形を抑えることができる。また、接続凸部４１とブラケット３０との接続部分に過大な力が作用するのを抑えることができる。これにより、支持脚４０の上端部４０ａの接続強度を高めることができる。
　また、ブラケット３０の下端面３４と、支持脚４０の上端面４３とを上下方向で対向させるのみで上記のような効果を奏するので、構造も簡易で、支持脚４０の上端部４０ａとブラケット３０との接続部分の大型化、構造の複雑化を抑えることができる。その結果、支持脚４０の上端部４０ａの接続強度を効率的に高めることが可能となる。 In the present embodiment, the connection convex portion 41 of the support leg 40 is connected to the bracket 30 above the lower end surface 34 with respect to the protrusion 32 of the bracket 30 provided on the lower surface 2b of the top plate 2. The upper end surface 43 of the support leg main body 42 faces the lower end surface 34 of the protrusion 32 in the up-down direction.
With such a configuration, when the support leg 40 is elastically deformed by the external forces F1 and F2 and the upper end surface 43 hits the lower end surface 34, the deformation load of the support leg 40 is received by the lower end surface 34. As a result, excessive deformation in the direction in which the inclination angle θ of the support leg 40 changes can be suppressed. In addition, it is possible to prevent an excessive force from acting on the connecting portion between the connecting convex portion 41 and the bracket 30. Thereby, the connection strength of the upper end portion 40a of the support leg 40 can be increased.
Further, since the above-described effect is obtained only by making the lower end surface 34 of the bracket 30 and the upper end surface 43 of the support leg 40 face each other in the vertical direction, the structure is simple, and the upper end portion 40a of the support leg 40 and the bracket 30. It is possible to suppress an increase in the size of the connecting portion with and the complexity of the structure. As a result, the connection strength of the upper end portion 40a of the support leg 40 can be efficiently increased.
　本実施形態では、支持脚本体４２が上方から下方に向かうに従い内外方向Ｄ３の外側Ｄｏに向けて傾斜し、下端面３４における内側端面３４ａ及び上端面４３における支持脚側内側端面４３ａが、支持脚本体４２が傾斜している側と反対側に位置する部分で対向している構成とした。
　このような構成によれば、例えば支持脚４０の傾斜角度θが小さくなる方向の外力Ｆ１が作用した場合に、内側端面３４ａと支持脚側内側端面４３ａとが突き当たることで、支持脚４０の過度な変形、及び接続凸部４１とブラケット３０との接続部分への過大な力の作用を抑えることができる。
　特に、本実施形態では、内側端面３４ａ及び支持脚側内側端面４３ａは、外側端面３４ｂ及び支持脚側外側端面４３ｂよりも、面積が大きいので、支持脚４０の傾斜角度θが小さくなる方向の外力Ｆ１に対する強度が、特に高められる。 In the present embodiment, the support leg main body 42 inclines toward the outside Do in the inward / outward direction D3 from the upper side to the lower side, and the inner end surface 34a of the lower end surface 34 and the support leg side inner end surface 43a of the upper end surface 43 are The main body 42 is configured to face each other at a portion located on the opposite side to the inclined side.
With such a configuration, for example, when the external force F1 in the direction in which the inclination angle θ of the support leg 40 decreases, the inner end surface 34a and the support leg side inner end surface 43a abut against each other, so that the support leg 40 is excessively moved. It is possible to suppress such deformation and the action of excessive force on the connecting portion between the connecting convex portion 41 and the bracket 30.
In particular, in the present embodiment, the inner end surface 34a and the support leg side inner end surface 43a have a larger area than the outer end surface 34b and the support leg side outer end surface 43b, so that the external force in the direction in which the inclination angle θ of the support leg 40 decreases. The strength against F1 is particularly increased.
　本実施形態では、支持脚本体４２が上方から下方に向かうに従い内外方向Ｄ３の外側Ｄｏに向けて傾斜し、下端面３４における外側端面３４ｂ及び上端面４３における支持脚側外側端面４３ｂが、支持脚本体４２が傾斜している側で対向している構成とした。
　このような構成によれば、支持脚４０の傾斜角度θが大きくなる方向の外力Ｆ２が作用した場合に、の外側端面３４ｂと支持脚側外側端面４３ｂとが突き当たる。これにより、支持脚４０の過度な変形、及び接続凸部４１とブラケット３０との接続部分への過大な力の作用を抑えることができる。 In the present embodiment, the support leg main body 42 inclines toward the outside Do in the inward / outward direction D3 from the upper side to the lower side, and the outer end surface 34b of the lower end surface 34 and the support leg side outer end surface 43b of the upper end surface 43 correspond to the support leg. The main body 42 is configured to face each other on the inclined side.
With such a configuration, when the external force F2 in the direction in which the inclination angle θ of the support leg 40 increases, the outer end surface 34b of the support leg 40 and the outer end surface 43b of the support leg abut against each other. As a result, it is possible to suppress excessive deformation of the support leg 40 and the action of excessive force on the connecting portion between the connecting convex portion 41 and the bracket 30.
　本実施形態では、接続凸部４１は、支持脚挿入凹部３３内で突出部３２に接続される構成とした。
　このような構成によれば、接続凸部４１と突出部３２との接続部分が外部に露呈せず、外観を向上させることができる。 In the present embodiment, the connection protrusion 41 is configured to be connected to the protrusion 32 in the support leg insertion recess 33.
With such a configuration, the connecting portion between the connecting convex portion 41 and the protruding portion 32 is not exposed to the outside, and the appearance can be improved.
　本実施形態では、第一支持脚締結ボルト６２によって接続された接続凸部４１の上端面４１ｔと支持脚挿入凹部３３の頂面３３ｅとが互いに突き当たる構成とした。
　このような構成によれば、支持脚４０の上端部４０ａが、より強固かつ安定的に固定される。 In the present embodiment, the upper end surface 41t of the connecting convex portion 41 and the top surface 33e of the supporting leg inserting concave portion 33, which are connected by the first supporting leg fastening bolt 62, abut against each other.
With such a configuration, the upper end portion 40a of the support leg 40 is more firmly and stably fixed.
　本実施形態では、第二支持脚締結ボルト６３が締結された状態で接続凸部４１の凸部内側面４１ｂと支持脚挿入凹部３３の内側壁面３３ｂとが互いに突き当たる構成とした。
　このような構成によれば、支持脚４０の上端部４０ａが、強固かつ安定的に固定される。 In the present embodiment, the convex inner surface 41b of the connecting convex portion 41 and the inner wall surface 33b of the support leg insertion concave portion 33 abut against each other while the second support leg fastening bolt 63 is fastened.
With such a configuration, the upper end portion 40a of the support leg 40 is firmly and stably fixed.
　本実施形態では、ブラケット３０は、フレーム２０に接続されている構成とした。
　このような構成によれば、互いに隣り合って配置される支持脚４０の上端部４０ａ同士は、フレーム２０を介して連結される。これにより、複数本の支持脚４０の接続強度が、さらに有効に高まる。 In this embodiment, the bracket 30 is connected to the frame 20.
According to such a configuration, the upper ends 40a of the support legs 40 arranged adjacent to each other are connected to each other via the frame 20. This further effectively increases the connection strength of the plurality of support legs 40.

With this configuration, the second support leg fastening bolt 63 is not exposed to the outside of the frame 20. As a result, it is possible to prevent the second support leg fastening bolts 63 from being exposed when the top plate 2 is viewed from the outside, and improve the appearance of the top plate fixture 1.
　本実施形態では、天板付什器１において、ブラケット３０がブラケット締結ボルト６１によって天板２に下方から締結される構成とした。
　このような構成によれば、支持脚４０の上端部４０ａが接続されるブラケット３０を、天板２に固定することで、支持脚４０の上端部４０ａを強固に固定することができる。また、ブラケット締結ボルト６１が天板２の上面２ａ側に露呈しないので、これによっても天板付什器１の外観を向上させることができる。 In this embodiment, in the furniture 1 with the top plate, the bracket 30 is configured to be fastened to the top plate 2 from below by the bracket fastening bolts 61.

（実施形態の変形例）
　上記実施形態では、突出部３２の下端面３４と支持脚本体４２の上端面４３とを、内外方向Ｄ３の両側、及び水平面内で内外方向Ｄ３に直交する方向の両側で対向させるようにしたが、これに限らない。突出部３２の下端面３４と支持脚本体４２の上端面４３とは、接続凸部４１の周方向の一部のみに設けてもよい。
　図１１は、本発明の実施形態に係る天板付什器１Ｂの変形例において、下端面３４Ｂと上端面４３Ｂとを、内外方向Ｄ３の内側にのみ設けた場合の構成を示す側断面図である。
　図１１に示すように、突出部３２Ｂの下端面３４Ｂは、支持脚挿入凹部３３に対し、内外方向Ｄ３の内側に形成されている。下端面３４Ｂは、内側凹湾曲面３２ｂと内側壁面３３ｂとの間に形成されている。 (Modification of the embodiment)
In the above-described embodiment, the lower end surface 34 of the protruding portion 32 and the upper end surface 43 of the support leg body 42 are made to face each other on both sides in the inward / outward direction D3 and on both sides in the direction orthogonal to the inward / outward direction D3 in the horizontal plane. , But not limited to this. The lower end surface 34 of the protruding portion 32 and the upper end surface 43 of the support leg body 42 may be provided only on a part of the connecting convex portion 41 in the circumferential direction.
FIG. 11 is a side cross-sectional view showing a configuration in the case where the lower end surface 34B and the upper end surface 43B are provided only on the inner side in the inward / outward direction D3 in the modified example of the top plate fixture 1B according to the embodiment of the present invention.
As shown in FIG. 11, the lower end surface 34B of the protrusion 32B is formed inside the support leg insertion recess 33 in the inward / outward direction D3. The lower end surface 34B is formed between the inner concave curved surface 32b and the inner wall surface 33b.
　支持脚４０Ｂにおいて、支持脚本体４２の上端面４３Ｂは、接続凸部４１に対し、内外方向Ｄ３の内側に形成されている。 In the support leg 40B, the upper end surface 43B of the support leg main body 42 is formed inside the connection convex portion 41 in the inward / outward direction D3.
　上端面４３Ｂは、接続凸部４１を支持脚挿入凹部３３に挿入した状態で、下端面３４Ｂと上下方向で対向（近接または当接）している。 The upper end surface 43B is opposed (close to or abutted) to the lower end surface 34B in the vertical direction in a state where the connection convex portion 41 is inserted into the support leg insertion concave portion 33.
　このような構成では、支持脚４０Ｂの傾斜角度θが小さくなる方向の外力Ｆ１（図９参照）が作用した場合に、下端面３４Ｂと上端面４３Ｂとが突き当たることで、支持脚４０Ｂの過度な変形、及び接続凸部４１とブラケット３０との接続部分への過大な力の作用を抑えることができる。これにより、支持脚４０Ｂの上端部４０ａの接続強度を高めることができる。 In such a configuration, when the external force F1 (see FIG. 9) in the direction in which the inclination angle θ of the support leg 40B decreases, the lower end surface 34B and the upper end surface 43B abut against each other, so that the support leg 40B is excessively moved. It is possible to suppress the deformation and the action of excessive force on the connecting portion between the connecting convex portion 41 and the bracket 30. Thereby, the connection strength of the upper end portion 40a of the support leg 40B can be increased.
　以上、本発明の好ましい実施例を説明したが、本発明はこれら実施例に限定されることはない。本発明の趣旨を逸脱しない範囲で、構成の付加、省略、置換、及びその他の変更が可能である。本発明は上述した説明によって限定されることはなく、添付の特許請求の範囲によってのみ限定される。
　例えば、上記実施形態では、支持脚４０を、上端部４０ａから下端部４０ｂに向かって、天板付什器１の外側に傾斜するようにしたが、これに限らない。支持脚４０を、上端部４０ａから下端部４０ｂに向かって、天板付什器１の内側に傾斜するようにしてもよい。
さらには、支持脚４０を傾斜させず、上端部４０ａから下端部４０ｂに向かって上下方向に直線状に延びるように設けてもよい。
　上記実施形態では、突出部３２の下端面３４，３４Ｂ及び支持脚本体４２の上端面４３，４３Ｂが接続凸部４１周りの全周、または接続凸部４１に対して内外方向Ｄ３の内側のみにおいて上下方向で対向する構成について説明したが、この構成のみに限られない。突出部３２の下端面及び支持脚本体４２の上端面は、接続凸部４１の周囲の少なくとも一部で対向していればよい。 Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. Additions, omissions, substitutions, and other changes can be made to the configuration without departing from the spirit of the present invention. The present invention is not limited by the above description, but only by the appended claims.
For example, in the above-described embodiment, the support leg 40 is inclined from the upper end portion 40a toward the lower end portion 40b toward the outside of the top plate fixture 1, but the present invention is not limited to this. You may make it the support leg 40 incline inward of the furniture 1 with a top plate toward the lower end part 40b from the upper end part 40a.
Further, the support leg 40 may be provided so as not to be inclined but to extend linearly in the vertical direction from the upper end portion 40a toward the lower end portion 40b.
In the above-described embodiment, the lower end surfaces 34, 34B of the protrusions 32 and the upper end surfaces 43, 43B of the support leg bodies 42 are provided around the entire circumference of the connection convex portion 41, or only inside the connection convex portion 41 in the inward / outward direction D3. Although the structure which opposes in the up-and-down direction was explained, it is not limited only to this structure. The lower end surface of the protrusion 32 and the upper end surface of the support leg main body 42 may be opposed to each other at least at a part of the periphery of the connection convex portion 41.
　また、上記実施形態では、ブラケット３０の構成について説明したが、その構成は一例に過ぎない。例えば、支持脚４０の上端部４０ａが接続されるブラケット３０は、支持脚挿入凹部３３を有するようにしたが、支持脚４０の上端部４０ａを固定できるのであれば、必ずしも凹部状とする必要はなく、天板２の下面２ｂから下方に突出していればよい。
　さらに、支持脚４０の上端部４０ａが接続される突起部として、天板２の下面２ｂに固定されるブラケット３０を示したが、突起部は、天板２の下面２ｂに一体的に設けてもよい。
　その他、本発明の趣旨を逸脱しない範囲で、上述した実施形態における構成要素を周知の構成要素に置き換えることは適宜可能であり、また、上述した各変形例を適宜組み合わせてもよい。 Further, although the configuration of the bracket 30 has been described in the above embodiment, the configuration is merely an example. For example, the bracket 30 to which the upper end portion 40a of the support leg 40 is connected has the support leg insertion concave portion 33, but if the upper end portion 40a of the support leg 40 can be fixed, it is not necessarily required to have a concave shape. Instead, it suffices that it projects downward from the lower surface 2b of the top plate 2.
Further, the bracket 30 fixed to the lower surface 2b of the top plate 2 is shown as the protruding portion to which the upper end portion 40a of the support leg 40 is connected, but the protruding portion is integrally provided on the lower surface 2b of the top plate 2. Good.
In addition, it is possible to appropriately replace the constituent elements in the above-described embodiments with well-known constituent elements without departing from the gist of the present invention, and the above-described modified examples may be appropriately combined.
　本発明によれば、支持脚の上端部の接続強度を効率的に高めることが可能となる。 According to the present invention, it becomes possible to efficiently increase the connection strength at the upper end of the support leg.
