Description

本発明は、主に家具・什器類を構成する部材同士を結合するための構造に関する。 The present invention mainly relates to a structure for connecting members constituting furniture and furniture.

複数の部材からなる家具・什器類の組立において、一方の部材に設けられた挿入部を他方の部材に形成された被挿入部（開口や間隙）に挿入、嵌合した上、両者をボルト等で締結することがしばしば行われる（例えば、下記特許文献を参照）。
特許３３１６１８７号公報特開２００４−０６８４９４号公報 In the assembly of furniture and fixtures consisting of multiple members, the insertion part provided in one member is inserted and fitted into the insertion part (opening or gap) formed in the other member, and both are bolted etc. It is often done with (see, for example, the following patent document).
Japanese Patent No. 3316187 JP 2004-068494 A

部材同士の相対位置を精確に位置決めするためには、挿入部と被挿入部との嵌め合いが緊密であるほうがよい。しかし、嵌め合いが緊密であればあるほど、組立作業には大きな労力を必要とする。このことは、特に双方の部材が大形または大重量のものである場合に問題となる。 In order to accurately position the relative positions of the members, it is preferable that the fitting between the insertion portion and the inserted portion is close. However, the closer the fit, the more labor is required for the assembly work. This is a problem especially when both members are large or heavy.

以上に鑑みてなされた本発明は、部材同士を結合する組立作業の施工性を向上させることを所期の目的としている。 The present invention made in view of the above is intended to improve the workability of assembling work for joining members together.

上述した課題を解決するべく、本発明では、一方の部材に対し他方の部材を所定の結合方向（挿入部を被挿入部に対し挿抜する方向である）から結合する構造であって、前記一方の部材側に設けられた挿入部と、前記挿入部の基端方にあって前記結合方向とは交差する方向に突き出している緊密係合部と、前記他方の部材側に設けられ前記結合方向に沿って前記挿入部が挿入される被挿入部と、前記一方の部材及び前記他方の部材に緊締力を及ぼし前記結合方向に沿って両部材を接近させながら前記緊密係合部を被挿入部に緊密に係合させる緊締手段とを具備し、前記結合方向に沿って延伸する複数個の横架部材を連結用ブロックを介して連結するものであり、連結用ブロックの一端側に横架部材を結合してなる構造体を前記一方の部材、その連結用ブロックの他端側に連結するべき横架部材を前記他方の部材としており、前記一対の横架部材における前記結合方向を向く端面同士を密接させるととともに、何れかの横架部材の端面から突き出した突出子を相手方の横架部材の端面に設けられた収容口に収容するようにしている部材の結合構造を構成した。このような結合構造を採用するならば、緊締手段による緊締力を利用して、一方の部材の緊密係合部と他方の部材の被挿入部とを緊密に嵌合させる（または、嵌合を深める）ことができるので、部材同士を結合する組立作業の施工性が向上する。 In order to solve the above-described problems, the present invention has a structure in which the other member is coupled to one member from a predetermined coupling direction (a direction in which the insertion portion is inserted into and removed from the insertion portion). An insertion portion provided on the member side, a tight engagement portion located in a proximal end of the insertion portion and projecting in a direction intersecting the coupling direction, and the coupling direction provided on the other member side The insertion portion into which the insertion portion is inserted, and the tight engagement portion is inserted into the insertion portion while applying a tightening force to the one member and the other member and bringing the two members closer along the coupling direction. And a plurality of horizontal members extending along the coupling direction are connected via a connecting block, and the horizontal member is connected to one end side of the connecting block. The structure formed by combining the one member and the The horizontal member to be connected to the other end of the connection block is the other member, and the end surfaces of the pair of horizontal members facing the coupling direction are brought into close contact with each other, and the end surface of any of the horizontal members The connecting structure of the member which was made to accommodate the protrusion protruded from the other in the accommodation port provided in the end surface of the other horizontal member was comprised. If such a coupling structure is employed, the tightly engaging portion of one member and the inserted portion of the other member are closely fitted (or fitted) using the fastening force of the fastening means. Therefore, the workability of the assembling work for joining the members is improved.

加えて、前記挿入部と前記緊密係合部との境界部が、前記結合方向に対して傾斜したテーパとなっていれば、緊締手段の緊締に伴い両部材が接近するにつれて徐々に嵌め合いが緊密になる。よって、緊締の過程が円滑化する。 In addition, if the boundary between the insertion portion and the tight engagement portion is a taper that is inclined with respect to the coupling direction, the fitting is gradually performed as both members approach as the fastening means is tightened. Get closer. Therefore, the tightening process is facilitated.

緊密係合部が、挿入部ではなく被挿入部の方に存在していてもよい。即ち、一方の部材に対し他方の部材を所定の結合方向から結合する構造であって、前記一方の部材側に設けられた被挿入部と、前記被挿入部の奥方にあって前記結合方向とは交差する方向に突き出している緊密係合部と、前記他方の部材側に設けられ前記結合方向に沿って前記被挿入部に挿入される挿入部と、前記一方の部材及び前記他方の部材に緊締力を及ぼし前記結合方向に沿って両部材を接近させながら前記緊密係合部を挿入部に緊密に係合させる緊締手段とを具備し、前記結合方向に沿って延伸する複数個の横架部材を連結用ブロックを介して連結するものであり、連結用ブロックの一端側に横架部材を結合してなる構造体を前記一方の部材、その連結用ブロックの他端側に連結するべき横架部材を前記他方の部材としており、前記一対の横架部材における前記結合方向を向く端面同士を密接させるととともに、何れかの横架部材の端面から突き出した突出子を相手方の横架部材の端面に設けられた収容口に収容するようにしている部材の結合構造を構成したとしても、同様の作用効果を奏し得る。 The tight engagement portion may exist not on the insertion portion but on the insertion portion. That is, a structure in which the other member is coupled to one member from a predetermined coupling direction, the inserted portion provided on the one member side, and the coupling direction at the back of the inserted portion, A tight engagement portion protruding in an intersecting direction, an insertion portion provided on the other member side and inserted into the insertion portion along the coupling direction, and the one member and the other member. Tightening means for exerting a tightening force and tightly engaging the tightly engaging portion with the insertion portion while bringing both members closer along the connecting direction, and a plurality of horizontal bridges extending along the connecting direction A member is connected via a connecting block, and a structure formed by connecting a horizontal member to one end side of the connecting block is to be connected to the one member and the other end side of the connecting block. The frame member is the other member, The end surfaces of the pair of horizontal members facing the coupling direction are brought into close contact with each other, and the protrusion protruding from the end surface of one of the horizontal members is accommodated in the accommodation port provided on the end surface of the other horizontal member. Even if the connecting structure of the members is configured, the same effect can be obtained.

前記被挿入部と前記緊密係合部との境界部が、前記結合方向に対して傾斜したテーパとなっていればより好ましい。 It is more preferable that the boundary portion between the inserted portion and the close engagement portion is a taper inclined with respect to the coupling direction.

前記緊締手段がボルトと、ボルトが螺合するナットとの組であり、前記ボルトが前記結合方向に対して傾斜した姿勢で配置されていれば、ボルトの軸方向に沿った緊張力が発生し、結合方向及び結合方向に直交する方向の双方に力を作用させることができる。これにより、相異なる方向を向く複数の面を介して部材同士を密接させ、複数方向の位置決めを同時に行うことが可能になる。 If the tightening means is a set of a bolt and a nut to which the bolt is screwed, and the bolt is arranged in an inclined posture with respect to the coupling direction, a tension force along the axial direction of the bolt is generated. The force can be applied to both the coupling direction and the direction orthogonal to the coupling direction. As a result, the members can be brought into close contact with each other via a plurality of surfaces facing different directions, and positioning in a plurality of directions can be performed simultaneously.

本発明の結合構造は、前記結合方向に沿って延伸する複数個の横架部材を連結用ブロックを介して連結する用途に供することができる。このとき、連結用ブロックの一端側に横架部材を結合してなる構造体を前記一方の部材、その連結用ブロックの他端側に連結するべき横架部材を前記他方の部材とする。たとえ連結用ブロックが比較的軽量であっても、横架部材が大重量であるならば、横架部材同士を連結する作業は多大な負担を伴う。本発明の結合構造を採用することにより、作業の負担を軽減可能である。その上、横架部材同士を精確に位置合わせできる利点もある。 The coupling structure of the present invention can be used for applications in which a plurality of horizontal members extending along the coupling direction are coupled via a coupling block. At this time, a structure formed by coupling a horizontal member to one end of the connecting block is referred to as the one member, and a horizontal member to be connected to the other end of the connecting block is referred to as the other member. Even if the connecting block is relatively light, if the horizontal member is heavy, the operation of connecting the horizontal members is very burdensome. By employing the coupling structure of the present invention, the work burden can be reduced. In addition, there is an advantage that the horizontal members can be accurately aligned.

前記一対の横架部材における前記結合方向を向く端面同士を密接させるととともに、何れかの横架部材の端面から突き出した突出子を相手方の横架部材の端面に設けられた収容口に収容するようにしていれば、両横架部材の密な結合に加えて、これら横架部材同士のねじれ（結合方向に沿った軸心回りの相対回転）を抑制することもできる。 The end surfaces of the pair of horizontal members facing the coupling direction are brought into close contact with each other, and the protrusion protruding from the end surface of one of the horizontal members is accommodated in the accommodation port provided on the end surface of the other horizontal member. If it does in this way, in addition to the close coupling | bonding of both horizontal members, the twist of these horizontal members (relative rotation around the shaft center along a coupling direction) can also be suppressed.

前記連結用ブロックが脚支柱に固定され、この脚支柱によって前記一対の横架部材が支持される構造は、デスク等の家具・什器類への適用に好適である。 The structure in which the connecting block is fixed to a leg column and the pair of horizontal members are supported by the leg column is suitable for application to furniture and furniture such as a desk.

本発明によれば、挿入部と被挿入部との嵌め合いが緊密となり、部材同士を強固に結合しかつ精確に位置決めできるとともに、部材同士を結合する組立作業の施工性も向上する。 According to the present invention, the fitting between the insertion portion and the insertion portion becomes tight, the members can be firmly coupled and accurately positioned, and the workability of the assembly work for coupling the members is improved.

天板案内用レール２２及びオプション案内用レール２３に包囲された中央部位は、側方に開口した筒状部２４となっている。筒状部２４の内周は、側断面視上方の対向壁２４１間が幅広、下方の対向壁２４２間が幅狭の多角形状をなす。筒状部２４の内周には、側断面視Ｃ字型の細チャネル２４３を複数設けている。図３に示すように、筒状部２４の底壁２４４は、横架部材２１の側端から内側方に向けて一部を切り欠いてある。加えて、その切欠縁２４５からやや内側方に遷移した箇所に、左右方向に拡張した長孔２４６を穿設している。図示例では、互いに平行な二個の長孔２４６が前後方向に離間して存在している。さらに、長孔２４６から内側方に遷移した箇所に、丸孔状の係合孔２４７を穿設している。 A central portion surrounded by the top plate guide rail 22 and the optional guide rail 23 is a cylindrical portion 24 opened to the side. The inner periphery of the cylindrical portion 24 has a polygonal shape in which the space between the opposing walls 241 at the upper side in the side sectional view is wide and the space between the lower opposing walls 242 is narrow. A plurality of narrow channels 243 having a C-shaped side sectional view are provided on the inner periphery of the cylindrical portion 24. As shown in FIG. 3, the bottom wall 244 of the cylindrical portion 24 is partially cut away from the side end of the horizontal member 21 inward. In addition, a long hole 246 that is expanded in the left-right direction is formed at a location slightly inward from the notch edge 245. In the illustrated example, there are two long holes 246 that are parallel to each other and spaced apart in the front-rear direction. Further, a round hole-like engagement hole 247 is formed at a location where the slot transitions inward from the long hole 246.

筒状部２４の底壁２４４は、横架部材２１の下面よりも高位置にある。そして、この底壁２４４の直下を、下方に開口した扁平なチャネル２５としている。チャネル２５によって前後に隔てられた横架部材２１の下面は互いに相寄る方向に延出し、チャネル２５の開口幅をその内幅よりも若干狭めている。チャネル２５の内周にも、側断面視Ｃ字型の細チャネル２５１を複数設けている。 The bottom wall 244 of the cylindrical portion 24 is at a higher position than the lower surface of the horizontal member 21. A flat channel 25 opened downward is formed directly below the bottom wall 244. The lower surface of the horizontal member 21 separated by the channel 25 in the front-rear direction extends in a direction close to each other, and the opening width of the channel 25 is slightly narrower than the inner width thereof. A plurality of narrow C-shaped channels 251 in a side sectional view are also provided on the inner periphery of the channel 25.

中間脚３は、上下方向に延伸する脚支柱３１の上面に横架部材２１連結用のブロック３２を固設した部材である。脚支柱３１は、板金材を折曲加工して作製した脚体を主体とする。図４、図５に示すように、脚体は、前後寸法が左右寸法よりも大きく、側面が平断面視前後方向の中間で凹んでいる。脚体の側面には、この脚体を左右方向に貫通する貫通窓３１２を形成している。図示例では、凹部３１１の横向面に貫通窓３１２が存在する。凹部３１１、貫通窓３１２は、給電コードや通信ケーブル等のコード類を配線するために利用できる。これら凹部３１１及び貫通窓３１２は、カバー３１４により隠蔽することが可能である。カバー３１４は、凹部３１１の平断面形状に対応した略チャネル状をなしている。カバー３１４を脚体に装着するには、カバー３１４の端縁から突き出しているフック爪３１５を、脚体の凹部３１１に予め穿ってあるフック孔３１３に掛け止める。カバー３１４を脚体に装着すると、カバー３１４の側面と脚支柱３１の側面とが略面一となり、カバー３１４及び凹部３１１によって配線通路が囲繞される。カバー３１４の上縁は凹部３１１の上縁よりも下方に位置し、配線通路の内外を連通する空隙を形成する。この空隙に、コード類を挿通することができる。同様に、カバー３１４の下縁は凹部３１１の下縁よりも上方に位置しており、やはり配線通路の内外を連通する空隙を形成する。カバー３１４の側面にも、配線通路の内外を連通する透窓３１６を穿設している。この透孔３１６は、カバー３１４を脱着操作するときに取手にもなる。 The intermediate leg 3 is a member in which a block 32 for connecting the horizontal member 21 is fixed on the upper surface of a leg column 31 extending in the vertical direction. The leg support 31 is mainly composed of a leg body produced by bending a sheet metal material. As shown in FIGS. 4 and 5, the leg body has a front-rear dimension that is larger than a left-right dimension, and the side surface is recessed in the middle of the front-rear direction in a plan view. A penetrating window 312 that penetrates the leg in the left-right direction is formed on the side of the leg. In the illustrated example, the through window 312 exists on the lateral surface of the recess 311. The recess 311 and the through window 312 can be used for wiring cords such as a power feeding cord and a communication cable. The recess 311 and the through window 312 can be concealed by the cover 314. The cover 314 has a substantially channel shape corresponding to the flat cross-sectional shape of the recess 311. In order to attach the cover 314 to the leg, the hook claw 315 protruding from the end edge of the cover 314 is hooked in the hook hole 313 previously drilled in the recess 311 of the leg. When the cover 314 is attached to the leg body, the side surface of the cover 314 and the side surface of the leg column 31 are substantially flush, and the wiring path is surrounded by the cover 314 and the recess 311. The upper edge of the cover 314 is located below the upper edge of the recess 311 and forms a gap that communicates the inside and the outside of the wiring path. Cords can be inserted into the gap. Similarly, the lower edge of the cover 314 is located above the lower edge of the recess 311 and also forms a gap that communicates the inside and outside of the wiring path. A transparent window 316 that communicates the inside and outside of the wiring passage is also formed in the side surface of the cover 314. The through hole 316 also serves as a handle when the cover 314 is attached and detached.

連結用ブロック３２は、脚支柱３１の上面に立脚した支基３２１と、支基３２１の上端に支持させた嵌合体３２２とを備える。本実施形態では、嵌合体３２２の右半部に第一の横架部材２１の側端部を嵌合し、左半部に第二の横架部材２１の側端部を嵌合して、両横架部材２１の側端面同士を接合、両横架部材２１を連結する。支基３２１は、平面視脚支柱３１の中央から立ち上がっており、その左右寸法が脚支柱３１の左右寸法よりも小さく、その前後寸法が脚支柱３１の前後寸法よりも小さい。対して、嵌合体３２２は、その左右寸法が脚支柱３１の左右寸法よりも大きく伸長している。嵌合体３２２は、上方に開放した略方形箱状をなす。嵌合体３２２の左右方向の中間には、略水平な係合板３２３を上方から接合している。係合板３２３を含む嵌合体３２２の外形は、前後対称かつ左右対称である。 The connection block 32 includes a support base 321 standing on the upper surface of the leg support 31 and a fitting body 322 supported on the upper end of the support base 321.

On the other hand, the fitting body 322 extends in the left-right dimension larger than the left-right dimension of the leg support 31. The fitting body 322 has a substantially square box shape opened upward. A substantially horizontal engagement plate 323 is joined from above in the middle of the fitting body 322 in the left-right direction. The outer shape of the fitting body 322 including the engagement plate 323 is symmetric in the front-rear direction and in the left-right direction.

係合板３２３には、前後方向に突き出した緊密係合部３４を設けてある。図６に示すように、緊密係合部３４は、正面視または背面視正面視嵌合体３２２の左右方向の中心線Ｌ上にある。図８に示すように、前側の緊密係合部３４の前縁は係合板３２３の前縁よりも前方に突き出し、後側の緊密係合部３４の後縁は係合板３２３の後縁よりも後方に突き出している。係合板３２３における緊密係合部３４とその周辺との境界部は、左右方向を向いたテーパ３４１状をなす。 The engagement plate 323 is provided with a tight engagement portion 34 protruding in the front-rear direction. As shown in FIG. 6, the tight engagement portion 34 is on the center line L in the left-right direction of the front-view or rear-view front-view fitting body 322. As shown in FIG. 8, the front edge of the front tight engagement portion 34 projects forward from the front edge of the engagement plate 323, and the rear edge of the rear tight engagement portion 34 is more than the rear edge of the engagement plate 323. Protruding backwards. A boundary portion between the close engagement portion 34 and its periphery in the engagement plate 323 has a taper 341 shape facing in the left-right direction.

嵌合体３２２の前板３２４及び後板３２５の（係合板３２３の存在しない）左右部位は、上縁が互いに離反する方向に屈曲して延出している。それら延出片３２６の高さ位置は、係合板３２３及び緊密係合部３４の高さ位置に略等しい。延出片３２６の外側端部は他の部分よりも前後方に突き出しているが、その前後縁の位置は係合板３２３における緊密係合部３４以外の部分の前後縁の位置に略等しく、緊密係合部３４ほどには突出していない。延出片３２６の前後縁と外側縁との隅角部は、面取りしてある。 The front plate 324 and the rear plate 325 of the fitting body 322 (left and right portions where the engagement plate 323 is not present) are bent and extended in a direction in which the upper edges are separated from each other. The height positions of the extending pieces 326 are substantially equal to the height positions of the engagement plate 323 and the tight engagement portion 34. The outer end of the extension piece 326 protrudes forward and rearward than the other part, but the position of the front and rear edges thereof is substantially equal to the position of the front and rear edges of the part other than the tight engagement part 34 in the engagement plate 323. It does not protrude as much as the engaging portion 34. The corners between the front and rear edges and the outer edge of the extension piece 326 are chamfered.

図９に示すように、嵌合体３２２の前板３２４及び後板３２５の中央部位にも、前後方向に突き出した緊密係合部３５を設けてある。図３に示すように、前後の緊密係合部３５は嵌合体３２２の下方部位、略同じ高さに位置している。図６に示すように、緊密係合部３５もまた、嵌合体３２２の左右方向の中心線Ｌ上にある。前板３２４及び後板３２５における緊密係合部３５とその周辺との境界部はテーパ３５１状をなす。 As shown in FIG. 9, a close engagement portion 35 protruding in the front-rear direction is also provided at the central portion of the front plate 324 and the rear plate 325 of the fitting body 322. As shown in FIG. 3, the front and rear tight engagement portions 35 are located at a lower part of the fitting body 322 at substantially the same height. As shown in FIG. 6, the tight engagement portion 35 is also on the center line L in the left-right direction of the fitting body 322. A boundary portion between the close engagement portion 35 and the periphery thereof in the front plate 324 and the rear plate 325 forms a taper 351 shape.

図７ないし図９に示すように、嵌合体３２２の底板３２７の左右両側部には、底ナット部３２８を設けている。底ナット部３２８は、底板３２７に貫通孔を穿ち、その貫通孔と同心軸上にナット部材を溶接等して配置してなる。図示例では、左右両側部のそれぞれにおいて、二個の底ナット部３２８が前後方向に離間して存在している。両底ナット部３２８の離間距離は、横架部材２１の二個の長孔２４６の離間距離に略等しい。また、嵌合体３２２の左右方向の中心線Ｌから底ナット部３２８までの距離は、横架部材２１の側端面から長孔２４６までの距離に概略対応している。嵌合体３２２の底板３２７と左右の側板との交差部位は、両者にまたがるように一部を切り欠いてある。嵌合体３２２の左右方向の中心線Ｌからその切欠縁３２９までの距離は、横架部材２１の側端面から係合孔２４７までの距離に概略対応している。 As shown in FIGS. 7 to 9, bottom nut portions 328 are provided on the left and right sides of the bottom plate 327 of the fitting body 322. The bottom nut portion 328 is formed by forming a through hole in the bottom plate 327 and welding a nut member on the concentric shaft with the through hole. In the illustrated example, two bottom nut portions 328 are present apart from each other in both the left and right side portions in the front-rear direction. The distance between the bottom nut portions 328 is substantially equal to the distance between the two long holes 246 of the horizontal member 21. The distance from the center line L in the left-right direction of the fitting body 322 to the bottom nut portion 328 roughly corresponds to the distance from the side end surface of the horizontal member 21 to the long hole 246. The intersection part of the bottom plate 327 of the fitting body 322 and the left and right side plates is partly cut out so as to straddle both. The distance from the center line L in the left-right direction of the fitting body 322 to the notch edge 329 roughly corresponds to the distance from the side end surface of the horizontal member 21 to the engagement hole 247.

嵌合体３２２の内部には、傾斜ナット部３７を設けている。傾斜ナット部３７は、左右方向に対して傾斜した傾斜板に貫通孔を穿ち、その貫通孔と同心軸上にナット部材を溶接等して配置してなる。傾斜ナット部３７は、嵌合体３２２の左右方向の中心線Ｌ付近から図中やや右寄りに遷移して所在している。後述するように、傾斜ナット部３７には斜め下方即ち左下方から緊締用ボルト８が螺着される。故に、嵌合体３２２の底板３２７及び支基３２１の左側方に、この緊締用ボルト８を通過させるための通過口３２０を形成している。 An inclined nut portion 37 is provided inside the fitting body 322. The inclined nut portion 37 is formed by forming a through hole in an inclined plate inclined with respect to the left-right direction, and welding a nut member or the like on a concentric shaft with the through hole. The inclined nut portion 37 is located slightly to the right in the figure from the vicinity of the center line L in the left-right direction of the fitting body 322. As will be described later, the tightening bolt 8 is screwed to the inclined nut portion 37 from obliquely downward, that is, from the lower left. Therefore, a passage port 320 for passing the fastening bolt 8 is formed on the left side of the bottom plate 327 and the support base 321 of the fitting body 322.

なお、脚支柱３１の上面にも、上下方向に突き出した緊密係合部３６を設けてある。緊密係合部３６もまた、嵌合体３２２の左右方向の中心線Ｌ上にある。前後対称に存在している緊密係合部３６の上面は、略同じ高さ位置にある。緊密係合部３６とその周辺との境界部はテーパ３６１状をなしており、緊密係合部３６の上面とともに切頭円錐形状を形作っている。 A close engagement portion 36 protruding in the vertical direction is also provided on the upper surface of the leg support 31. The tight engagement portion 36 is also on the center line L in the left-right direction of the fitting body 322. The upper surfaces of the tight engagement portions 36 that exist symmetrically in the front-rear direction are substantially at the same height. A boundary portion between the tight engagement portion 36 and its periphery forms a taper 361, and forms a truncated conical shape together with the upper surface of the close engagement portion 36.

横架部材２１同士を連結するに際して、まず、第一の横架部材２１を中間脚３に結合する。連結用ブロック３２の右端を第一の横架部材２１の左側端に臨ませ、その嵌合体３２２を横架部材２１の筒状部２４に挿入する。このとき、前板３２４及び後板３２５の下方部位が下方の対向壁２４２に近接し、上端にある延出片３２６及び係合板３２３が上方の対向壁２４１の上縁近傍に近接する。嵌合体３２２を支持する支基３２１（の右半部）は、横架部材２１の底壁２４４に形成している切欠２４５の内に収まる。同時に、横架部材２１の下面から筒状部２４の底壁２４４の上面までを含む下端領域２６が、脚支柱３１の上面と嵌合体３２２の底板３２７の下面との間隙３３に挿入された状態となる。 When connecting the horizontal members 21, first, the first horizontal member 21 is coupled to the intermediate leg 3. The right end of the connecting block 32 faces the left end of the first horizontal member 21, and the fitting body 322 is inserted into the cylindrical portion 24 of the horizontal member 21. At this time, the lower portions of the front plate 324 and the rear plate 325 are close to the lower facing wall 242, and the extending piece 326 and the engaging plate 323 at the upper end are close to the vicinity of the upper edge of the upper facing wall 241. The support base 321 (the right half thereof) that supports the fitting body 322 is accommodated in a notch 245 formed in the bottom wall 244 of the horizontal member 21. At the same time, the lower end region 26 including the lower surface of the horizontal member 21 to the upper surface of the bottom wall 244 of the cylindrical portion 24 is inserted into the gap 33 between the upper surface of the leg column 31 and the lower surface of the bottom plate 327 of the fitting body 322. It becomes.

そして、図６に示すように、第一の横架部材２１の左端面が嵌合体３２２の左右方向の中心線Ｌ近傍に達するまで、嵌合体３２２を奥深く進入させる。結果、嵌合体３２２の下方部位の緊密係合部３５が下方の対向壁２４２に緊密に係合し、上端の緊密係合部３４が上方の対向壁２４１に緊密に係合する。並びに、脚支柱３１の上面の緊密係合部３６が横架部材２１の下面に緊密に係合し、嵌合体３２２の底板３２７が筒状体の底壁２４４に緊密に係合する。両者を緊密に嵌合せしめるには労力を要するが、この時点では比較的軽量な中間脚３を操作して作業を行うことができるので困難ではない。 Then, as shown in FIG. 6, the fitting body 322 is caused to enter deeply until the left end surface of the first horizontal member 21 reaches the vicinity of the center line L in the left-right direction of the fitting body 322. As a result, the tight engagement portion 35 in the lower part of the fitting body 322 is closely engaged with the lower opposing wall 242, and the upper tight engagement portion 34 is closely engaged with the upper opposing wall 241. In addition, the tight engagement portion 36 on the upper surface of the leg column 31 is closely engaged with the lower surface of the horizontal member 21, and the bottom plate 327 of the fitting body 322 is closely engaged with the bottom wall 244 of the cylindrical body. Although it takes labor to fit the two closely, it is not difficult at this point because the relatively lightweight intermediate leg 3 can be operated.

その後、治具６及び固定用ボルト９を使用して、第一の横架部材２１を中間脚３に締結し固定する。図３、図７に示すように、治具６は、基板６１の外側端部に上方に突き出す突起６２を設けたものである。突起６２の外周は、横架部材２１の係合孔２４７の内周に略合致する。基板６１には、この基板６１を上下に貫通するボルト孔６３を穿設している。図示例では、二つのボルト孔６３が前後方向に離間して存在する。両ボルト孔６３の離間距離は、横架部材２１の二個の長孔２４６の離間距離に略等しい。また、ボルト孔６３から突起６２までの左右方向に沿った距離は、横架部材２１の長孔２４６から係合孔２４７までの距離に概略対応している。 Thereafter, the first horizontal member 21 is fastened and fixed to the intermediate leg 3 using the jig 6 and the fixing bolt 9. As shown in FIGS. 3 and 7, the jig 6 is provided with a protrusion 62 protruding upward at an outer end portion of the substrate 61. The outer periphery of the protrusion 62 substantially matches the inner periphery of the engagement hole 247 of the horizontal member 21. Bolt holes 63 are formed in the substrate 61 so as to penetrate the substrate 61 up and down. In the illustrated example, there are two bolt holes 63 spaced apart in the front-rear direction. The distance between the bolt holes 63 is substantially equal to the distance between the two long holes 246 of the horizontal member 21. Further, the distance along the left-right direction from the bolt hole 63 to the protrusion 62 roughly corresponds to the distance from the long hole 246 to the engagement hole 247 of the horizontal member 21.

横架部材２１の側端面が嵌合体３２２の左右方向の中心線Ｌの近くにあるとき、平面視横架部材２１の長孔２４６と嵌合体３２２の底ナット部３２８とが重なり合う。また、横架部材２１の係合孔２４７が嵌合体３２２の側端部の切欠３２９の下方に位置する。この状態で、治具６の基板６１を下方から横架部材２１の筒状部２４の底壁２４４に当接させるようにして、ボルト孔６３を長孔２４６に重ね合わせるとともに突起６２を係合孔２４７に挿入し、その先方を嵌合体３２２の切欠縁３２９近傍に配置する。治具６は、横架部材２１のチャネル２５内に収まる。それから、固定用ボルト９をボルト孔６３及び長孔２４６に挿通して底ナット部３２８に螺合し緊締すれば、第一の横架部材２１と中間脚３との結合作業が終了する。治具６の突起６２は、嵌合体３２２の切欠縁３２９に係合することを通じて、嵌合体３２２が横架部材２１の筒状部２４の深奥に入り込みすぎてしまうことを防ぐ、換言すれば横架部材２１の側端面を嵌合体３２２の左右方向の中心線Ｌ近傍に適切に位置づける役割を果たす。 When the side end surface of the horizontal member 21 is near the center line L in the left-right direction of the fitting body 322, the elongated hole 246 of the horizontal member 21 in plan view and the bottom nut portion 328 of the fitting body 322 overlap each other. Further, the engagement hole 247 of the horizontal member 21 is positioned below the notch 329 at the side end of the fitting body 322. In this state, the base plate 61 of the jig 6 is brought into contact with the bottom wall 244 of the cylindrical portion 24 of the horizontal member 21 from below so that the bolt hole 63 is overlapped with the long hole 246 and the protrusion 62 is engaged. The tip is inserted into the hole 247 and the tip of the hole 247 is disposed in the vicinity of the notch edge 329 of the fitting body 322. The jig 6 is accommodated in the channel 25 of the horizontal member 21. Then, when the fixing bolt 9 is inserted into the bolt hole 63 and the long hole 246 and screwed into the bottom nut portion 328 and tightened, the connecting operation of the first horizontal member 21 and the intermediate leg 3 is completed. The protrusion 62 of the jig 6 is engaged with the notch edge 329 of the fitting body 322 to prevent the fitting body 322 from entering too deep into the cylindrical portion 24 of the horizontal member 21, in other words, the lateral direction. It plays the role of appropriately positioning the side end surface of the frame member 21 in the vicinity of the center line L in the left-right direction of the fitting body 322.

次いで、第二の横架部材２１を中間脚３に結合する。第一の横架部材２１の場合と同様、連結用ブロック３２の左端を第二の横架部材２１の右側端に臨ませ、その嵌合体３２２を横架部材２１の筒状部２４に挿入する。そして、第二の横架部材２１の右端面が嵌合体３２２の左右方向の中心線Ｌ近傍に達するまで嵌合体３２２を奥深く進入させる。しかしながら、上記の作業は、長尺で重量のある横架部材２１を中間脚３に結合して構築した構造体に、やはり長尺で重量のある横架部材２１を緊密に嵌合せしめるものであるだけに、必ずしも容易ではない。 Next, the second horizontal member 21 is coupled to the intermediate leg 3. As in the case of the first horizontal member 21, the left end of the connecting block 32 faces the right end of the second horizontal member 21, and the fitting body 322 is inserted into the tubular portion 24 of the horizontal member 21. . Then, the fitting body 322 is caused to enter deeply until the right end surface of the second horizontal member 21 reaches the vicinity of the center line L in the left-right direction of the fitting body 322. However, the above-described work is to closely fit the long and heavy horizontal member 21 to the structure constructed by connecting the long and heavy horizontal member 21 to the intermediate leg 3. It is not always easy.

そこで、図６中に二点差線で示すように第二の横架部材２１を緊密嵌合部３４、３５、３６に係合する手前まで嵌挿した後、緊締手段を操作して、第二の横架部材２１を第一の横架部材２１に接近する方向に変位させ、嵌合体３２２に緊密に嵌合させる。本実施形態において、緊締手段とは、嵌合体３２２の内部に設けている傾斜ナット部３７と、この傾斜ナット部３７に螺合する緊締用ボルト８との組である。図７に示すように、緊締用ボルト８は左右方向に対して傾斜した姿勢、より具体的には傾斜ナット部３７に略直交する姿勢に配置する。緊締用ボルト８の緊締により、当該ボルト８の軸方向に沿った緊張力が発生するため、第二の横架部材２１と嵌合体３２２とが左右方向にも上下方向にも互いに引き付けられることとなる。 Therefore, as shown by a two-dot chain line in FIG. 6, the second horizontal member 21 is inserted and inserted to a position before engaging the tight fitting portions 34, 35, 36, and then the fastening means is operated to The horizontal member 21 is displaced in a direction approaching the first horizontal member 21 and closely fitted to the fitting body 322. In this embodiment, the tightening means is a set of an inclined nut portion 37 provided inside the fitting body 322 and an tightening bolt 8 screwed into the inclined nut portion 37. As shown in FIG. 7, the tightening bolt 8 is disposed in a posture inclined with respect to the left-right direction, more specifically in a posture substantially orthogonal to the inclined nut portion 37. When the tightening bolt 8 is tightened, a tension force along the axial direction of the bolt 8 is generated, so that the second horizontal member 21 and the fitting body 322 are attracted to each other both in the left-right direction and in the up-down direction. Become.

緊締用ボルト８を傾斜ナット部３７に螺着するにあたり、緊締用ボルト８の座となる治具７を使用する。図３、図７に示すように、治具７は、基板７１と、基板７１の前後縁からそれぞれ垂下した前板７４及び後板７５と、前板７４及び後板７５に溶接等して固設したボルト座部７６とを備える。ボルト座部７６は、傾斜ナット部３７（の傾斜板）と略平行な方向を向いており、傾斜ナット部３７（のナット部材）と同心軸上に挿通孔を穿設している。基板７１の外側端部には、上方に突き出す突起７２を設けてある。突起７２の外周は、横架部材２１の係合孔２４７の内周に略合致する。加えて、基板７１には、この基板７１を上下に貫通し左右方向に拡張したボルト孔７３を穿設している。図示例では、二つのボルト孔７３が前後方向に離間して存在する。両ボルト孔７３の離間距離は、横架部材２１の二個の長孔２４６の離間距離に略等しい。また、ボルト孔７３から突起７２までの左右方向に沿った距離は、横架部材２１の長孔２４６から係合孔２４７までの距離に概略対応している。基板７１の内側端部は一部を切り欠いてあるが、この切欠７７は緊締用ボルト８の軸との干渉を避けるためのものである。 When the tightening bolt 8 is screwed to the inclined nut portion 37, the jig 7 serving as a seat for the tightening bolt 8 is used. As shown in FIGS. 3 and 7, the jig 7 is fixed by welding or the like to the substrate 71, the front plate 74 and the rear plate 75 suspended from the front and rear edges of the substrate 71, and the front plate 74 and the rear plate 75, respectively. And a bolt seat portion 76 provided. The bolt seat portion 76 faces a direction substantially parallel to the inclined nut portion 37 (inclined plate thereof), and has an insertion hole on a concentric shaft with the inclined nut portion 37 (nut member thereof). A protrusion 72 protruding upward is provided at the outer end of the substrate 71. The outer periphery of the protrusion 72 substantially matches the inner periphery of the engagement hole 247 of the horizontal member 21. In addition, the board 71 is provided with a bolt hole 73 that penetrates the board 71 vertically and extends in the left-right direction. In the illustrated example, there are two bolt holes 73 spaced apart in the front-rear direction. The distance between the bolt holes 73 is substantially equal to the distance between the two long holes 246 of the horizontal member 21. The distance along the left-right direction from the bolt hole 73 to the protrusion 72 roughly corresponds to the distance from the long hole 246 to the engagement hole 247 of the horizontal member 21. A part of the inner end portion of the substrate 71 is notched, but the notch 77 is for avoiding interference with the shaft of the tightening bolt 8.

前述の治具６と同じく、この治具７の基板７１を下方から横架部材２１の筒状部２４の底壁２４４に当接させるようにして、ボルト孔７３を長孔２４６に重ね合わせつつ突起７２を係合孔２４７に挿入する。治具７は、横架部材２１のチャネル２５内に収まる。突起７２の先方は嵌合体３２２の切欠縁３２９付近に位置するものの、切欠縁３２９との間には隙間がある。しかる後、緊締用ボルト８を左下方から右上方に向けてボルト座部７６に挿通し、通過口３２０を経て嵌合体３２２の内部に突入させ、傾斜ナット部３７に螺合し緊締する。すると、緊締用ボルト８の頭が治具７のボルト座部７６に着座し、当該ボルト８の軸方向に沿った緊張力が治具７を介して第二の横架部材２１に作用する。特に、左右方向に沿った緊張力成分が、突起７２と係合孔２４７との係合を介して横架部材２１に伝達される。この緊張力により、第二の横架部材２１が相対的に嵌合体３２２及び第一の横架部材２１に接近する右方向に引き寄せられる。結果、嵌合体３２２の下方部位の緊密係合部３５が下方の対向壁２４２に緊密に係合し、上端の緊密係合部３４が上方の対向壁２４１に緊密に係合する。並びに、脚支柱３１の上面の緊密係合部３６が横架部材２１の下面に緊密に係合し、嵌合体３２２の底板３２７が筒状体の底壁２４４に緊密に係合する。 Similar to the jig 6 described above, the substrate 71 of the jig 7 is brought into contact with the bottom wall 244 of the cylindrical portion 24 of the horizontal member 21 from below, and the bolt hole 73 is overlaid on the long hole 246. The protrusion 72 is inserted into the engagement hole 247. The jig 7 is accommodated in the channel 25 of the horizontal member 21. Although the tip of the protrusion 72 is located in the vicinity of the notch edge 329 of the fitting body 322, there is a gap between the notch edge 329. Thereafter, the tightening bolt 8 is inserted into the bolt seat portion 76 from the lower left to the upper right, and is inserted into the fitting body 322 through the passage port 320, and is screwed into the inclined nut portion 37 and tightened. Then, the head of the tightening bolt 8 is seated on the bolt seat 76 of the jig 7, and the tension force along the axial direction of the bolt 8 acts on the second horizontal member 21 via the jig 7. In particular, the tension component along the left-right direction is transmitted to the horizontal member 21 through the engagement between the protrusion 72 and the engagement hole 247. By this tension force, the second horizontal member 21 is pulled in the right direction relatively approaching the fitting body 322 and the first horizontal member 21. As a result, the tight engagement portion 35 in the lower part of the fitting body 322 is closely engaged with the lower opposing wall 242, and the upper tight engagement portion 34 is closely engaged with the upper opposing wall 241. In addition, the tight engagement portion 36 on the upper surface of the leg column 31 is closely engaged with the lower surface of the horizontal member 21, and the bottom plate 327 of the fitting body 322 is closely engaged with the bottom wall 244 of the cylindrical body.

第二の横架部材２１が嵌合体３２２に緊密に嵌合し、第二の横架部材２１の側端面と第一の横架部材２１の側端面とが密接したら、固定用ボルト９をボルト孔７３及び長孔２４６に挿通して底ナット部３２８に螺合し緊締する。これにより、第二の横架部材２１と中間脚３との結合作業が終了する。ひいては、第一の横架部材２１と第二の横架部材２１との連結が完成する。 When the second horizontal member 21 is tightly fitted to the fitting body 322 and the side end surface of the second horizontal member 21 and the side end surface of the first horizontal member 21 are in close contact with each other, the fixing bolt 9 is attached to the bolt. The hole 73 and the long hole 246 are inserted into the bottom nut portion 328 and tightened. Thereby, the joining operation | work of the 2nd horizontal member 21 and the intermediate leg 3 is complete | finished. As a result, the connection of the first horizontal member 21 and the second horizontal member 21 is completed.

因みに、本実施形態では、両横架部材２１のねじれ、即ち左右方向に沿った軸心回りの相対回転を抑制するべく、横架部材２１の端面に開口している細チャネル２４３、２５１に予めピン２７を取着しておき、そのピン２７を相手方の横架部材２１の細チャネル２４３、２５１に収容するようにしている。ピン２７は、基端側が細チャネルに螺着可能な雄ねじ（タッピングねじ）、先端側が先細りのテーパであり、テーパの根本部分が細チャネルの内周に緊密に嵌合し得る外周面を有している。ピン２７の先端面には、ドライバー等の工具を使用して螺挿するために適したマイナス形状、プラス形状等の溝を形成しておく。図２、図９に示すように、本実施形態では、双方の横架部材２１にそれぞれ複数本のピン２７を螺着している。図示例では、第一の横架部材２１における前側の細チャネル２４３、２５１に二本のピン２７を螺着し、かつ第二の横架部材２１における後側の細チャネル２４３、２５１に二本のピン２７を螺着している（ともに、最上の細チャネル２４３及び最下の細チャネル２５１を使用）。第二の横架部材２１を水平に１８０度回転させると、第一の横架部材２１と同じになる。 Incidentally, in this embodiment, in order to suppress the twisting of both the horizontal members 21, that is, the relative rotation around the axial center along the left-right direction, the narrow channels 243 and 251 opened in the end surface of the horizontal member 21 are previously provided. The pin 27 is attached, and the pin 27 is accommodated in the narrow channels 243 and 251 of the counterpart horizontal member 21. The pin 27 has a male screw (tapping screw) that can be screwed to the narrow channel on the base end side, a tapered taper on the tip end side, and an outer peripheral surface in which the root portion of the taper can be tightly fitted to the inner periphery of the thin channel. ing. A groove having a minus shape or a plus shape suitable for screwing using a tool such as a screwdriver is formed on the tip surface of the pin 27. As shown in FIGS. 2 and 9, in the present embodiment, a plurality of pins 27 are screwed to both the horizontal members 21. In the illustrated example, two pins 27 are screwed into the front narrow channels 243 and 251 in the first horizontal member 21, and two pins are disposed in the rear thin channels 243 and 251 in the second horizontal member 21. The pin 27 is screwed (both use the uppermost thin channel 243 and the lowermost thin channel 251). When the second horizontal member 21 is rotated 180 degrees horizontally, the same as the first horizontal member 21 is obtained.

既に嵌合体３２２の右半部に第一の横架部材２１の側端部を嵌合している状態で、嵌合体３２２の左半部を第二の横架部材２１の筒状部２４に挿入すると、第一の横架部材２１の側端面から突き出したピン２７のテーパが第二の横架部材２１における（ピン２７を螺着していない）細チャネル２４３、２５１内に進入し、第二の横架部材２１の側端面から突き出したピン２７のテーパが第一の横架部材２１における細チャネル２４３、２５１内に進入する。しかる後、緊締用ボルト８による緊締を行うと、両横架部材２１が接近して端面同士が密接するとともに、ピン２７の根本部分が細チャネル２４３、２５１に緊密に嵌合することとなる。 With the side end of the first horizontal member 21 already fitted to the right half of the fitting body 322, the left half of the fitting body 322 is replaced with the cylindrical portion 24 of the second horizontal member 21. When inserted, the taper of the pin 27 protruding from the side end face of the first horizontal member 21 enters into the narrow channels 243 and 251 in the second horizontal member 21 (the pin 27 is not screwed). The taper of the pin 27 protruding from the side end surface of the second horizontal member 21 enters the narrow channels 243 and 251 in the first horizontal member 21. After that, when tightening with the tightening bolts 8 is performed, both lateral members 21 approach and the end surfaces come into close contact with each other, and the base portion of the pin 27 is tightly fitted to the narrow channels 243 and 251.

本実施形態によれば、第一の横架部材２１及び脚支柱３１に対し第二の横架部材２１を所定の結合方向即ち左右方向から結合する構造であって、第一の部材及び脚支柱３１の側に設けられた挿入部たる嵌合体３２２と、嵌合体３２２の基端方にあって嵌合体３２２を挿抜する方向とは直交する方向に突き出している緊密係合部３４、３５と、第二の横架部材２１の側に設けられ左右方向に沿って嵌合体３２２が挿入される被挿入部たる筒状部２４と、嵌合体３２２が筒状部２４に挿入された後に操作され、連結用ブロック３２及び第二の横架部材２１に緊締力を及ぼし挿抜方向に沿って両部材を接近させながら緊密嵌合部３４、３５を筒状部２４に緊密に係合させる緊締手段とを具備する部材の結合構造を構成したため、緊締手段による緊締力を利用でき、部材同士を結合する組立作業の施工性が向上する。 According to the present embodiment, the second horizontal member 21 is coupled to the first horizontal member 21 and the leg column 31 from a predetermined coupling direction, that is, the left-right direction. A fitting body 322 that is an insertion portion provided on the side of 31, a tight engagement portion 34, 35 that is in the proximal end of the fitting body 322 and protrudes in a direction orthogonal to the direction in which the fitting body 322 is inserted and removed, The cylindrical portion 24 which is an insertion portion provided on the second horizontal member 21 side and into which the fitting body 322 is inserted along the left-right direction, and is operated after the fitting body 322 is inserted into the cylindrical portion 24, Tightening means for tightly engaging the tight fitting portions 34 and 35 with the cylindrical portion 24 while exerting a tightening force on the connecting block 32 and the second horizontal member 21 and bringing both members close along the insertion / extraction direction. Tightening means by means of fastening means The available, thereby improving workability of the assembling work for coupling the members together.

また、第一の横架部材２１及び脚支柱３１の側に設けられた被挿入部たる間隙３３と、間隙３３の奥方にあって下端領域２６を挿抜する方向とは直交する突き出している（いわば、被挿入部の内縁よりも内方に突き出している）緊密係合部３６と、第二の横架部材２１の側に設けられ左右方向に沿って前記間隙３３に挿入される挿入部たる下端領域２６と、前記間隙３３に前記下端領域２６が挿入された後に操作され、連結用ブロック３２及び第二の横架部材２１に緊締力を及ぼし挿抜方向に沿って両部材を接近させながら緊密係合部３６を前記下端領域２６に緊密に係合させる緊締手段とを具備する部材の結合構造を構成したため、緊締手段による緊締力を利用でき、部材同士を結合する組立作業の施工性が向上する。 Further, the gap 33 which is an insertion portion provided on the side of the first horizontal member 21 and the leg column 31 protrudes in the back of the gap 33 and orthogonal to the direction in which the lower end region 26 is inserted and removed (so to speak). A tight engagement portion 36 projecting inward from the inner edge of the inserted portion, and a lower end serving as an insertion portion provided on the second lateral member 21 side and inserted into the gap 33 along the left-right direction. The region 26 is operated after the lower end region 26 is inserted into the gap 33, and exerts a tightening force on the connecting block 32 and the second horizontal member 21 so that both members are brought close together in the insertion / removal direction. Since the member coupling structure including the fastening means for tightly engaging the joining portion 36 with the lower end region 26 is configured, the fastening force by the fastening means can be used, and the workability of the assembly work for joining the members is improved. .

加えて、緊密係合部３４、３５、３６の境界部が、挿入部を挿抜する方向に対して傾斜したテーパ３４１、３５１、３６１となっているため、緊締手段の緊締に伴い両部材が接近するにつれて徐々に嵌め合いが緊密になる。よって、緊締の過程が円滑化する。 In addition, since the boundary portions of the tight engagement portions 34, 35, and 36 are tapered 341, 351, and 361 that are inclined with respect to the direction in which the insertion portion is inserted and removed, both members approach as the fastening means is tightened. The fit gradually becomes closer as you go. Therefore, the tightening process is facilitated.

前記緊締手段が緊締用ボルト８と、緊締用ボルト８が螺合するナットたる傾斜ナット部３７との組であり、緊締用ボルト８が挿抜方向に対して傾斜した姿勢で配置されているため、緊締用ボルト８の軸方向に沿った緊張力が発生し、左右方向及び上下方向の双方に力を作用させることができる。これにより、相異なる方向を向く複数の面を介して部材同士を密接させ、複数方向の位置決めを同時に行うことが可能になる。即ち、横架部材２１の端面同士を密接させることができ、かつ横架部材２１の下面と緊密係合部３６の上面とを密接させることができる。さらには、横架部材２１の筒状部２４の底壁２４４の上面と嵌合体３２２の底板３２７の下面とを密接させることもできる。 The tightening means is a set of a tightening bolt 8 and an inclined nut portion 37 which is a nut to which the tightening bolt 8 is screwed, and the tightening bolt 8 is arranged in an inclined posture with respect to the insertion / extraction direction. A tension force along the axial direction of the tightening bolt 8 is generated, and the force can be applied in both the left-right direction and the up-down direction. As a result, the members can be brought into close contact with each other via a plurality of surfaces facing different directions, and positioning in a plurality of directions can be performed simultaneously. That is, the end surfaces of the horizontal member 21 can be brought into close contact with each other, and the lower surface of the horizontal member 21 and the upper surface of the tight engagement portion 36 can be brought into close contact with each other. Furthermore, the upper surface of the bottom wall 244 of the cylindrical portion 24 of the horizontal member 21 and the lower surface of the bottom plate 327 of the fitting body 322 can be brought into close contact with each other.

本結合構造は、挿抜方向に沿って延伸する複数個の横架部材２１を連結用ブロック３２を介して連結する用途に供することができる。このとき、連結用ブロック３２の一端側即ち右端側に横架部材２１を結合してなる構造体と、その連結用ブロック３２の他端側即ち左端側に連結するべき横架部材２１とを結合することと相成る。たとえ連結用ブロック３２が比較的軽量であっても、横架部材２１が大重量であるならば、横架部材２１同士を連結する作業は多大な負担を伴う。本結合構造を採用することにより、緊締手段が発揮する緊締力を利用して構造体の嵌合体３２２に横架部材２１を緊密に嵌合せしめることができるため、作業の負担を軽減可能である。その上、横架部材２１同士を精確に位置合わせできる利点もある。 The present coupling structure can be used for the purpose of connecting a plurality of horizontal members 21 extending along the insertion / extraction direction via a connection block 32. At this time, the structure formed by connecting the horizontal member 21 to one end side, that is, the right end side of the connecting block 32 and the horizontal member 21 to be connected to the other end side, that is, the left end side of the connecting block 32 are connected. To do with. Even if the connecting block 32 is relatively light, if the horizontal member 21 is heavy, the work of connecting the horizontal members 21 with each other involves a great burden. By adopting this coupling structure, it is possible to tightly fit the horizontal member 21 to the fitting body 322 of the structure using the tightening force exerted by the tightening means, so that the work load can be reduced. . In addition, there is an advantage that the horizontal members 21 can be accurately aligned.

一対の横架部材２１における挿抜方向を向く端面同士を密接させるととともに、何れかの横架部材２１の端面から突き出した突出子たるピン２７を相手方の横架部材２１の端面に設けられた収容口たる細チャネル２４３、２５１に収容するようにしているため、両横架部材２１の密な結合に加えて、これら横架部材２１同士のねじれ防止が可能になる。 The end surfaces of the pair of horizontal members 21 facing the insertion / extraction direction are brought into close contact with each other, and the pins 27 that project from the end surfaces of any of the horizontal members 21 are provided on the end surface of the other horizontal member 21 Since it is accommodated in the narrow channels 243 and 251 which are mouths, in addition to the tight coupling of the two horizontal members 21, it is possible to prevent the horizontal members 21 from being twisted.

前記連結用ブロック３２が脚支柱３１に固定され、この脚支柱３１によって前記一対の横架部材２１が支持される構造は、デスク１等の家具・什器類への適用に好適である。 The structure in which the connecting block 32 is fixed to the leg column 31 and the pair of horizontal members 21 are supported by the leg column 31 is suitable for application to furniture and furniture such as the desk 1.

For example, the application target of the present invention is not limited to the use of connecting the components of the desk. It is allowed to mount the engaging device according to the present invention on various furniture and fixtures.

緊締用ボルトが、部材の結合方向（左右方向）に対して平行な姿勢で配置されることを妨げない。 It does not prevent the tightening bolts from being arranged in a posture parallel to the connecting direction (left-right direction) of the members.

また、緊締手段は、ボルトとナットとの組には限られない。結合対象となる一方の部材及び他方の部材の両方を挟圧する（これら部材とは別個の）クランプ装置等を緊締手段として使用することも考えられる。 Further, the tightening means is not limited to a set of bolts and nuts. It is also conceivable to use a clamp device or the like (separate from these members) that clamps both the one member and the other member to be combined as fastening means.
