以上述べたように本発明による構造用枠材の連結具によれば、外側面に長手方向に延びる係合溝部が形成された２本の構造用枠材を使用し、上記２本の構造用枠材の何れか一方の構造用枠材の一端面を何れか他方の構造用枠材の外側面に直交する方向から当接させ、その際上記何れか一方の構造用枠材の係合溝部と何れか他方の構造用枠材の係合溝部が連通するような位置関係となり、その状態で上記２本の構造用枠材を連結固定する構造用枠材の連結具において、上記構造用枠材の連結具は、上記直交配置された２本の構造用枠材における夫々の係合溝部内に同時に挿入され、該係合溝部の内側に張り出した係合突部に係止される２つの係止爪を直交する２辺に備えた左右一対のサイドハウジングと、上記左右一対のサイドハウジングの間に形成された可動空間内に収容され、上記左右一対のサイドハウジングにおける対向する２組の係止爪間に進退する押圧片を直交する２辺に備えた可動体と、上記左右一対のサイドハウジングにおける係止爪が設けられていない基端部にあてがわれて取り付けられるエッジカバーと、上記エッジカバーに設けられるナット部に螺合されることによって上記可動体の押圧片を上記左右一対のサイドハウジングにおける対向する係止爪間に進入させて構造用枠材の係合溝部の底面に当接させる連結固定位置と、上記エッジカバーに設けられるナット部に対する螺合を解除されることにより押圧片を上記左右一対のサイドハウジングにおける対向する係止爪間から退出させて可動空間内に位置させる連結解除位置との間で上記可動体を移動させる押しボルトと、を具備しているので、上記押圧片を連結固定位置に位置させることによって対向する係止爪を幅方向の左右に押し広げることによって係止爪を構造用枠材の係合溝部に対して形成されている係合突部に確実に係止させることができる。
又、押圧片を上記係合溝部の底面に当接させる押圧片の反作用によって左右のサイドハウジングが斜め上方に引き上げられることによってサイドハウジングに対して形成されている係止爪が上記係合突部を上方に引き上げるように作用し、係止爪の係合突部に対する係止状態が強固になる。したがって、構造用枠材が受ける種々の方向の衝撃荷重や偏心荷重あるいは部品の摩耗等の経時的要因が生じたとしても係合溝部から係止片が脱落することはない。又、左右のサイドハウジング内に可動体を介在させる比較的簡単な構造によって構成されているから構造用枠材の連結具のコスト削減にも寄与し得る。
又、上記可動体に対して押圧面が設けられていない他の一辺に押しボルトの下面が当接する傾斜した押圧面を設け、該押圧面にガイドロックを立ち上げ、上記エッジカバーに設けたガイド穴に摺動自在に嵌合するように構成した場合には、押しボルトが傾斜した押圧面を押すことによって可動体は斜め下方に向けて移動するようになり、直交配置されている２本の構造用枠材の対応する２本の係合溝部に対して同時に係止爪による連結固定が実行されるようになる。又、ガイドロックとガイド穴の摺接案内作用によって、可動体の移動が案内され、正確且つ円滑な可動体の移動が実行される。
又、ガイドロックの先端面に連結ブラケットを取り付けて、押しボルトを緩めて行く時に、押しボルトの上端面を連結ブラケットの下面に当接させることによって、上記可動体を斜め上方に引き上げて連結解除位置に至らせるようにした場合には、押しボルトと一体になって可動体が移動するようになり、押しボルトの位置によって押圧片の係止爪に対する進入及び退出位置を把握することができる。又、可動体を連結解除位置に移動させるための別途の移動手段が不要になる。
又、エッジカバーに対して左右側面外方に突出する引上げ凸部を形成し、左右一対のサイドハウジングに上記引上げ凸部と係合する係合穴部を形成した場合には、可動体を連結固定位置に移動させた時、押圧片が係合溝部の底面を押圧する反作用によって生ずる係止爪の係合突部に対する引上げ力が増強されて、確実に左右一対のサイドハウジングを斜め上方に引き上げることが可能になる。
又、上記構成の構造用枠材の連結具を同規格の構造用枠材の連結固定に使用するのではなく、構造用枠材と他部材との連結固定に使用する場合には、上記係止爪と押圧片は少なくとも１組設けられていればよく、その場合にも上記と同様の係合溝部に対する係止爪の強固な連結固定が実行されるから構造用枠材が受ける種々の方向の衝撃荷重や偏心荷重あるいは部品の摩耗等の経時的要因に起因する係合溝部からの係止片の脱落が防止される。 As described above, according to the structural frame member connector of the present invention, the two structural frame members having the engaging grooves extending in the longitudinal direction on the outer surface are used, and the two structural frame members are used. One end surface of one of the structural frame members of the frame member is brought into contact with the outer surface of one of the other structural frame members from the direction orthogonal thereto, and at this time, the engaging groove portion of one of the above structural frame members In the structural frame member coupling device for connecting and fixing the two structural frame members in such a state that the engaging groove portions of the other structural frame member communicate with each other. The material connecting tool is inserted into each of the engaging groove portions of the two structural frame members arranged orthogonally at the same time, and is engaged with two engaging protrusions projecting inside the engaging groove portions. Between a pair of left and right side housings having locking claws on two orthogonal sides, and the pair of left and right side housings A movable body that is accommodated in the formed movable space and includes two pressing pieces that are perpendicular to each other, and a pair of left and right side housings; An edge cover that is attached by being attached to a base end portion that is not provided with a locking claw, and a pressing piece of the movable body that is screwed into a nut portion that is provided on the edge cover, thereby the pair of left and right side housings The connecting and fixing position to be brought into contact with the bottom surface of the engaging groove portion of the structural frame member by entering between the engaging claws opposed to each other, and the press piece by releasing the screw engagement with the nut portion provided in the edge cover. A push that moves the movable body between a pair of left and right side housings and a connection release position that retracts from between the opposing locking claws and is located in the movable space. The locking claw is moved to the engagement groove portion of the structural frame member by expanding the opposing locking claw to the left and right in the width direction by positioning the pressing piece at the coupling fixing position. It can be made to latch reliably to the engaging protrusion currently formed with respect.
In addition, the latching claws formed on the side housings are formed on the side housings by raising the left and right side housings obliquely upward by the reaction of the pressing pieces that abut the pressing pieces on the bottom surface of the engaging groove. And the locking state of the locking claw with respect to the engaging protrusion is strengthened. Therefore, even if a temporal factor such as impact load or eccentric load in various directions received by the structural frame material or wear of parts occurs, the locking piece does not fall off from the engaging groove. Moreover, since it is comprised by the comparatively simple structure which interposes a movable body in the left and right side housing, it can also contribute to the cost reduction of the connection tool of a structural frame material.
In addition, an inclined pressing surface with which the lower surface of the pressing bolt abuts is provided on the other side where the pressing surface is not provided with respect to the movable body, a guide lock is raised on the pressing surface, and a guide provided on the edge cover When it is configured to be slidably fitted into the hole, the movable body moves obliquely downward by pushing the inclined pressing surface of the push bolt, and the two orthogonally arranged Coupling and fixing by the locking claws are simultaneously performed on the two corresponding engaging groove portions of the structural frame material. Moreover, the movement of the movable body is guided by the sliding contact guide action of the guide lock and the guide hole, and the movable body is accurately and smoothly moved.
Also, when the connecting bracket is attached to the front end surface of the guide lock and the push bolt is loosened, the upper end surface of the push bolt is brought into contact with the lower surface of the connecting bracket, and the movable body is lifted obliquely upward to release the connection. In the case of reaching the position, the movable body moves integrally with the push bolt, and the entry and withdrawal positions of the pressing piece with respect to the locking claw can be grasped by the position of the push bolt. Further, no separate moving means for moving the movable body to the connection release position is required.
In addition, when a raised convex part that protrudes outward from the left and right side surfaces is formed with respect to the edge cover, and an engagement hole that engages with the raised convex part is formed in the pair of left and right side housings, the movable body is connected. When moved to the fixed position, the pulling force against the engaging protrusion of the locking claw generated by the reaction of the pressing piece pressing the bottom surface of the engaging groove is increased, and the pair of left and right side housings are surely pulled upward. It becomes possible.
In addition, when the structural frame connecting member having the above structure is not used for connecting and fixing the structural frame member of the same standard but used for connecting and fixing the structural frame member to other members, the above-mentioned It is sufficient that at least one set of the pawl and the pressing piece is provided, and even in that case, since the locking pawl is firmly connected and fixed to the engaging groove portion as described above, various directions received by the structural frame member The locking piece is prevented from falling off from the engaging groove due to factors such as impact load, eccentric load or wear of parts.

次にこのようにして構成される本発明の構造用枠材の連結具１の作動態様を（１）連結解除状態と、（２）連結途中の状態と、（３）連結固定状態とに分けて具体的に説明する。
（１）連結解除状態｛図２、４、５、６、１４（ａ）参照｝
六角レンチ５９を連結ブランケット３７の穴部６１から押しボルト１０の六角穴７１内に挿嵌して、押しボルト５７を緩める方向に回転させて行くと、押しボルト１０は、斜め上方に向けて回転しながら移動し、上端面１０ｂが連結ブランケット３７の下面３７ａに当接し、可動体８を斜め上方に引き上げるように作用する。 Next, the operation mode of the structural frame connector 1 of the present invention configured as described above is divided into (1) a connection release state, (2) a connection middle state, and (3) a connection fixed state. Will be described in detail.
(1) Connection release state {See FIGS. 2, 4, 5, 6, 14 (a)}
When the hexagon wrench 59 is inserted into the hexagon hole 71 of the push bolt 10 from the hole 61 of the connecting blanket 37 and is rotated in the loosening direction, the push bolt 10 rotates obliquely upward. The upper end surface 10b comes into contact with the lower surface 37a of the connecting blanket 37 and acts to lift the movable body 8 obliquely upward.

可動体８の直交する２片４１、４３に対して設けられている押圧片２３、２３が対向する係止爪１３、１３間から退出し、本体部８ａと共に可動空間１１内に至ると、対向する係止爪１３、１３は平坦な内側の面が当接状態になり、対向する係止爪１３、１３の幅方向の突出量が最小になって、図示のように構造用枠材３における係合溝部５の係合突部５ａ間の隙間を通って係合溝部５内に係止爪１３、１３が進入することができるようになる。 When the pressing pieces 23, 23 provided for the two orthogonal pieces 41, 43 of the movable body 8 retreat from between the opposing locking claws 13, 13 and reach the movable space 11 together with the main body portion 8 a, they face each other. The engaging claws 13 and 13 are brought into contact with the flat inner surface, and the protruding amount in the width direction of the opposing engaging claws 13 and 13 is minimized. The locking claws 13 and 13 can enter the engagement groove portion 5 through the gap between the engagement protrusions 5a of the engagement groove portion 5.

（２）連結途中の状態｛図７、８、９、１４（ｂ）参照｝
六角レンチ５９を連結ブラケット３７の穴部穴部６１から押しボルト１０の六角穴７１内に挿嵌して、押しボルト５７を締め付ける方向に回転させて行くと、押しボルト５７は斜め下方に向けて回転しながら移動し、下端面１０ａが可動体８の押圧面４７に当接し、可動体８を斜め下方に押し下げるように作用する。 (2) State in the middle of connection {Refer to Drawing 7, 8, 9, 14 (b)}
When the hexagon wrench 59 is inserted into the hexagon hole 71 of the push bolt 10 from the hole portion 61 of the connecting bracket 37 and rotated in the direction in which the push bolt 57 is tightened, the push bolt 57 is directed obliquely downward. The lower end surface 10a abuts against the pressing surface 47 of the movable body 8, and acts so as to push the movable body 8 downward obliquely.

これに伴って、可動体８の直交する２辺４１、４３に対して設けられている押圧片２３、２３は、内側の面が当接状態になっている対向する係止爪１３、１３を左右外方に押し広げるようにして係止爪１３、１３間の隙間に進入する。
上記係止爪１３、１３の左右外方への移動によって、係止爪１３の外側の部分に形成されている鉤状の爪部１３ａが構造用枠材３の係合溝部５に形成されている係合突部５ａに係止されるようになり、係合突部５ａに対して左右外方に押し広げるような力を与えて連結が開始される。 Along with this, the pressing pieces 23, 23 provided for the two orthogonal sides 41, 43 of the movable body 8 have the opposing locking claws 13, 13 whose inner surfaces are in contact with each other. It enters into the gap between the locking claws 13 and 13 so as to spread outward in the left and right directions.
By the movement of the locking claws 13, 13 to the left and right outwards, a hook-shaped claw portion 13 a formed on the outer portion of the locking claw 13 is formed in the engagement groove portion 5 of the structural frame member 3. The engagement projection 5a is locked, and a force is applied to the engagement projection 5a so as to push it outward in the left and right directions, thereby starting the connection.

（３）連結固定状態｛図３、１０、１１、１２、１４（ｃ）参照｝
セットボルト１０の六角穴７１内に挿嵌されている六角レンチ５９を更に締め付ける方向に回転させて行くと、押しボルト１０の下端面１０ａは引き続き押圧面４７を押圧し、可動体８を斜め下方に押し下げるように作用する。
これに伴って、可動体８の直交する２辺４１、４３に対して設けられている押圧片２３、２３は、対向する係止爪１３、１３を左右外方に押し広げながら係止爪１３、１３の下端から突出した状態になる。 (3) Connection fixed state {Refer to Drawing 3, 10, 11, 12, 14 (c)}
When the hexagon wrench 59 inserted in the hexagon hole 71 of the set bolt 10 is further rotated in the tightening direction, the lower end surface 10a of the push bolt 10 continues to press the pressing surface 47, and the movable body 8 is moved obliquely downward. Acts to push down.
Along with this, the pressing pieces 23, 23 provided on the two orthogonal sides 41, 43 of the movable body 8 push the opposing locking claws 13, 13 outward and expand the locking claws 13. , 13 projecting from the lower end.

押圧片２３、２３の進行が進み押圧片２３、２３の端面２３ａ、２３ａが係合溝部５の底面５ｂに当接すると、押圧片２３、２３による押圧力は構造用枠材１に対して伝達されるようになる。
しかし、構造用枠材１は固定状態にあるため、上記押圧力に対する力の反作用として左右一対のサイドハウジング７Ｌ、７Ｒを斜め上方に移動させる力が作用するようになる。
そして、対向する係止爪１３、１３は係止爪１３、１３間に進入した押圧片２３の作用によって左右外方に押し広げられた状態を保って、更に係合溝部５の係合突部５ａを上方に引き上げるような力を与えて強固な連結・固定状態が形成される。 When the pressing pieces 23, 23 progress and the end faces 23 a, 23 a of the pressing pieces 23, 23 abut against the bottom surface 5 b of the engaging groove 5, the pressing force by the pressing pieces 23, 23 is transmitted to the structural frame material 1. Will come to be.
However, since the structural frame member 1 is in a fixed state, a force that moves the pair of left and right side housings 7L and 7R obliquely upward acts as a reaction of the force against the pressing force.
And the engaging claw 13 and 13 which opposes maintain the state expanded by right and left outward by the effect | action of the press piece 23 which approached between the claw 13 and 13, and also the engagement protrusion of the engagement groove part 5 A strong connection / fixed state is formed by applying a force to pull 5a upward.

このように本発明では対向する係止爪１３、１３を左右外方に押し広げる力に加えて係合突部５ａに係止されている係止爪１３、１３を上方に引き上げる力によって直交・配置された２本の構造用枠材３、３と本発明の連結具１との強固な連結・固定が図れ、構造用枠材３が受ける種々の方向の衝撃荷重や偏心荷重あるいは摩耗等の経時的要因に起因する係合溝部５からの係止片１３の脱落を効果的に防止することが可能になる。   In this way, in the present invention, in addition to the force that pushes the opposing locking claws 13 and 13 outward in the left and right directions, the force that pulls up the locking claws 13 and 13 that are locked to the engaging protrusion 5a is orthogonal. The two structural frame members 3 and 3 arranged and the connector 1 of the present invention can be firmly connected and fixed, so that the structural frame member 3 receives impact load, eccentric load, wear, etc. in various directions. It is possible to effectively prevent the locking piece 13 from dropping from the engaging groove portion 5 due to a factor over time.

次に、図１５を参照して本発明の第２の実施の形態を説明する。例えば、押圧片２３を係止爪１３から退出させる方向の可動体８の動きを、図１５に示すようにリターンスプリング７３によって実行することも可能である。
即ち、図１５に示す構造用枠材の連結具１Ａは、左右のサイドハウジング７Ｌ、７Ｒと可動体８との間に一例として圧縮コイルスプリングによって構成されているリターンスプリング７３が縮設されていて、常時、可動体８を斜め上方に移動させる付勢力が作用するように構成されている。 Next, a second embodiment of the present invention will be described with reference to FIG. For example, the movement of the movable body 8 in the direction in which the pressing piece 23 is retracted from the locking claw 13 can be executed by the return spring 73 as shown in FIG.
That is, in the structural frame member 1A shown in FIG. 15, a return spring 73 formed by a compression coil spring is provided between the left and right side housings 7L and 7R and the movable body 8 as an example. The urging force that moves the movable body 8 obliquely upward is always applied.

したがって、押しボルト１０を締め付けることによって可動体８はリターンスプリング７３の付勢力に抗して斜め下方に移動し、押しボルト１０を緩めることによって可動体８は押しボルト１０からの押圧力が解除されて、リターンスプリング７３の付勢力によって斜め上方に移動するようになる。
そして、本実施の形態の場合には、連結ブラケット３７は不要であるから省略されている。
そして、このような構成でも前記第１の実施の形態の場合と略同様の作用、効果が奏せられる。 Accordingly, the movable body 8 moves obliquely downward against the urging force of the return spring 73 by tightening the push bolt 10, and the movable body 8 is released from the pressing force from the push bolt 10 by loosening the push bolt 10. Thus, it moves obliquely upward by the urging force of the return spring 73.
In the case of the present embodiment, the connection bracket 37 is omitted because it is unnecessary.
Even with such a configuration, substantially the same operations and effects as in the case of the first embodiment can be achieved.

次に、図１６を参照して本発明の第３の実施の形態を説明する。すなわち、本発明による構造用枠材の連結具１は、図１６に示すように構造用枠材３に他部材７５を連結固定する目的で使用することも可能である。
この場合には、図１６に示す構造用枠材の連結具１Ｂのように、係止爪１３、１３と押圧片２３は１組のみ設ければよく、押しボルト１０の作用方向を押圧片２３の移動方向と一致させることが可能である。
尚、本実施の形態の場合には、左右のサイドハウジング７Ｌ、７Ｒに対して他部材７５の一例である締付け具等を吊持するための吊持リング７７が一例として設けられている。
そして、このような構成でも前記第１の実施の形態の場合と略同様の作用、効果が奏せられる。 Next, a third embodiment of the present invention will be described with reference to FIG. That is, the structural frame member connector 1 according to the present invention can be used for the purpose of connecting and fixing the other member 75 to the structural frame member 3 as shown in FIG.
In this case, it is sufficient to provide only one set of the locking claws 13 and 13 and the pressing piece 23 as in the structural frame member 1B shown in FIG. It is possible to make it coincide with the moving direction.
In the case of the present embodiment, a suspension ring 77 for suspending a fastener or the like, which is an example of the other member 75, is provided as an example with respect to the left and right side housings 7L and 7R.
Even with such a configuration, substantially the same operations and effects as in the case of the first embodiment can be achieved.

尚、本発明は前記第１〜第３の実施の形態に限定されるものではない。
例えば、前記第１〜第３の実施の形態の場合には、横断面形状が概略正方形の構造用枠材を例に挙げて説明したが、それに限定されるものではなく、長方形等様々な形状のものが想定される。
又、構造用枠材の横断面形状も図示したものに限定されず様々な形状のものが考えられる。
その他、図示した構成はあくまで一例である。 The present invention is not limited to the first to third embodiments.
